Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of, and claims the benefit of, U.S. application Ser. No. 14/167,783, filed Jan. 29, 2014, which claims the benefit of U.S. Provisional Application No. 61/849,662, filed Jan. 30, 2013.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Examples of the subject matter disclosed herein generally relate to apparatus, methods and systems for an independent air register vent and grill assembly that can be easily installed and removed by a homeowner or general handyman, in many cases without the use of tools.

2. Discussion of Background

The present invention relates to the common comfort demands, convenience and expense of over-heated or overcooled rooms whether occupied or unoccupied.

Ventilation systems are common place in all modern structures such as offices or homes providing a comfortable indoor climate controlled condition for the occupants. The occupants are able to turn on their air conditioning during the summer and the heater during the winter as needed to provide for a comfortable living environment. The typical ventilation system generates a flow of cool or warm air to each room of the home or building through ventilation outlets mounted on ceilings, walls and floors of each room of the structure.

Typical ventilating configurations have common disadvantages in that they must generate sufficient cool or warm air flowing towards all the rooms whether occupied are not. Other disadvantages are related to the inability of the system's main blower to provide an adequate volume of conditioned air flowing to each single room throughout the home or structure. Given the fact that various rooms in a particular structure tend to be unequal in size and volume, this causes a system with a centrally located thermostat incapable of satisfying the predetermined desired temperature equally throughout the rooms in a particular home or structure. The described shortfalls are not only inconvenient in terms of comfort but waste energy, resources and money.

In response to these challenges the most common way to regulate desired airflow is to adjust, through a range of positions through the main body of the air vent frame, the ventilation louvers by manually moving the lever or gear attached to the louver system. However, most of the ventilation outlets are typically mounted on the ceiling of the room or a remote part of the floor of the room, not easily accessible to the occupant.

Ceiling mounted air vent registers in most cases present a great deal of inconvenience for the user as they must climb up to the ceiling in order to manually move the lever or gear to regulate the desired air flowing through the register outlet. There could be numerous occasions throughout the day when an occupant may want to adjust a particular room's temperature. The exercise of physically moving the louver control lever is simply too inconvenient, therefore leaving the room environment inefficiently controlled and the occupant dissatisfied.

The HVAC industries' answer to the common problem of unbalanced air circulation is to install a zoning system, also known as an automatic balancing system. A zone is an area of a house with independent heating and/or cooling control. Zoning segments the house into particular areas that can be individually controlled in an efficient manner. The normal zoning in the average home is a two (2) zone system. This type of zoning is fine for houses around 2000 or more sq. feet and can be controlled very efficiently using a two or more zones. Zoning systems require expert HVAC technicians to design and install. The cost may be prohibitive to many homeowners.

U.S. Pat. No. 6,435,962 to Herron et al discloses a vent register for controlling the flow of air from a heating and cooling duct system. The register includes a rack and pinion operating mechanism for controlling the movement of the damper louvers. Herron '962 fails to disclose or suggest non-manual, computer-controlled adjustment settings of louver positions into partially open or partially closed positions, and fails to disclose a length-adjustable vent housing and length-adjustable louvers. Herron '962 fails to disclose or suggest a removable power assembly motor with receiver and controller, enabling the same vent to be in-the-field configured to a desired length and configured for either manual or remote operation. Herron '962 fails to disclose or suggest a length-adjustable grill cover that may be swung open from the vent or removed, providing access to a replaceable filter.

U.S. Pat. No. 6,692,349 to Brinkerhoff et al discloses a computer-controlled air vent which includes: a top plate; a base connected to the top plate; a component housing connected to the top plate and to the base; a plurality of louvers rotatably positioned within the base; a force generating means connected to the louvers to rotate them between an open position and a closed position; a temperature sensor to sense a room temperature; a computer processor; a memory; a wireless transceiver; a bus to connect the processor and the memory; and a remote control device to control the opening and closing of the louvers. Brinkerhoff '349 fails to disclose or suggest setting the louvers into other than open and closed positions, use of one way transmission (a transmitter and receiver, reducing complexity and cost, rather than paired transceivers) to set louver positions into partially open or partially closed positions, and fails to disclose a length-adjustable vent housing and length-adjustable louvers. Brinkerhoff '349 fails to disclose or suggest a removable power assembly motor with receiver and controller, enabling the same vent to be in-the-field configured to a desired length and configured for either manual or remote operation. Brinkerhoff '349 fails to disclose or suggest a length-adjustable grill cover that may be swung open from the vent or removed, providing access to a replaceable filter.

U.S. Pat. No. 8,020,777 to Kates discloses a self-contained zoned system unit that includes a register vent, a power supply, a thermostat, and a motor to open and close the register vent. Kates '777 fails to disclose or suggest a length-adjustable vent housing and length-adjustable louvers. Kates '777 fails to disclose or suggest a removable power assembly motor with receiver and controller, enabling the same vent to be in-the-field configured to a desired length and configured for either manual or remote operation. Kates '777 fails to disclose or suggest a length-adjustable grill cover that may be swung open from the vent or removed, providing access to a replaceable filter. Further, Kate uses a thermostat.

In addition, there are numerous other prior art attempts that employ a user programmable thermostat to control the room temperature by repeatedly opening and closing a vent automatically. These devices have major drawbacks in that they are typically difficult for the user to program. Their internal programming and components are complex and come with expense. Each repeated opening or closing of a vent drains power at the vent, requiring significant power capacity at the vent location.

DETAILED DESCRIPTION

U.S. Provisional Application No. 61/849,662, filed Jan. 30, 2013 for ADJUSTABLE REGISTER VENT AND GRILL ASSEMBLY DESIGNED TO FIT ALL SIZE STANDARD AIR DISTRIBUTION BOOT OPENINGS by Richard D. Frank is herein incorporated by reference in its entirety. U.S. Provisional Ser. No. 14/167,783, filed Jan. 29, 2014 for ADJUSTABLE REGISTER VENT AND GRILL ASSEMBLY DESIGNED TO FIT ALL SIZE STANDARD AIR DISTRIBUTION BOOT OPENINGS by Richard D. Frank is herein incorporated by reference in its entirety.

An object of an example of the present invention is to provide an independent air register vent and grill assembly that improves on the shortcomings of prior art devices. In example, the assembly allows for the means to adjust the register frame and louver components, rotatable and non-rotatable, to match standard length and width openings in a manner that arranges the entire assembly to conform to all common standard size vent boot outlets. In one embodiment, within the main register frame assembly is a small programmable wireless receiver attached to the electric battery motorized self-regulating air register assembly, adjustable housing frame, adjustable louvers in the housing frame regulating the air flow volume, separate wireless remote controlled linear sliding potentiometer transmitter plate, digital thermometer fixed to the wireless transmitter device, accurately indicating changes in room temperatures as a result of adjusting the degree of said remote controlled louvers. Furthermore, the complete adjustable register and grill system can be easily installed and removed by a homeowner or general handyman without the use of tools. In addition, the adjustable register vent and grill assembly as described is designed in a manner that allows for a manual version of the main register and grill assembly to operate without the micro controlled components to provide the same fully adjustable features of the “one size fits all” installation that will require manual adjustments of the louvers housed in the main register frame.

The present invention relates to home or commercial Heat Ventilation and Air Conditioning systems, more particularly designed to address comfort levels, reduce utility costs, and simplify vent register sizing selections when replacing older registers, “one size fits all”, while providing a tool free installation and removal of the complete register or just the grill assembly only for cleaning purposes.

In examples, a main object of the present invention is to provide the industry with an inexpensive fully adjustable battery powered electric remote-controlled air vent register frame and grill assembly suitable for installation in the most common size standard residential and commercial air duct boot compartment boxes.

The advancement of the linear register frame and grill adjustment provides the industry service installer the ability to fit the new adjustable register into irregular ceiling, wall and floor air supply openings that currently fall between industry standard size openings without having the additional expense to modify the interior surface to conform with a standard register size.

In one example, a servicemen's ability to address customers' concerns with respect to particle contamination, foul smells/mold, duct bacterial distribution and general airborne contaminates can be addressed with an attached replaceable filter.

The advancement of the linear register frame and grill adjustment provides the interior paint industry the ability to limit their warehouse and mobile inventory of grills that are typically required to be replaced as the result of a newly painted wall or ceiling surface.

In examples, a motorized configuration allows for individual room zoning. More options are available to the serviceman when it comes to minor, inexpensive approaches to individual room comfort control without typically expensive full home zoning options. Each motorized system is designed to display individual ambient room temp by use of a thermometer integrated into a remote controller.

Register installation is now made easier because of the compression fit register sizing which allows the installer to complete the process by simple insertion. In one example, the compression fit holds the register in place while completing a more secure screw attachment process, if needed.

Benefits from a retail observation: Small “mom & pop” hardware stores don't have the ability to invest in the required minimum inventory necessary to accommodate even the most common standard consumer registers due to the number of sizes associated with typical residential homes. Hardware stores which specialize in “hard-to-find” hardware benefit by having a “universal” style air register that covers a range of register opening sizes.

The present invention benefits retail stores and commercial supply houses—whether “Big Box”, “mom & pop”, paint and decorator stores, or any other outlets—through overall inventory reduction in the number of standard size registers needed to be kept in stock. This reduces the chances that customers would have no other option than to shop a second supplier before returning to their jobsite.

Other benefits by offering a reduction in inventory as a result of the “one size” design include: less shipping, handling, packaging and shelf space that could be used for other product lines.

FIGS. 1 through 12 illustrate various examples of the invention and operation.

FIG. 1 illustrates a 3-D exploded perspective view of an example of the adjustable register system 1 with its sub-assemblies. Adjustable register system 1, in this example, includes three major sub-assemblies: a register assembly 100 which is fitted into a register opening of a heating or air conditioning system, a grill assembly 200 which is sized or fitted to conform to the size of grill assembly 200, and a motor-receiver & remote-transmitter system 300 which includes a detached remote-transmitter system 310 to communicate to a motor-receiver-controller assembly 340 attached to register assembly 100.

In one example, the members of the system are positioned and arranged to enable register assembly 100 to be configured without motor-receiver & remote-transmitter system 300. This enables the provider of the register vent solution to maintain a wider variety of solution options while maintaining a minimum inventory footprint. For example, register assembly 100 is usable for a solution that requires a sizeable register (vent) but does not require remote control or the expense of remote control. In this example, installation and use of register assembly 100 in this manual configuration still allows for an optional field upgrade, later, to the motorized remote-control system.

A further economic advantage is realized with this modular system approach in that the trouble or expense may not be desired of having every register (vent) in the home motorized with remote control. Typically, only a few rooms are in need of remote-controlled vent adjustment. Yet, a consistent set of registers (vents) throughout the home is desired. Having every vent configured for motorized and remote operation may be prohibitive and/or unnecessary—leading to lost sales and/or less than fully desired solutions (because the cost of having every register motorized may lose the entire sale). In this example, a range of choices are available and may be made using the presently presented system. Some rooms/vents may be fully configured with motor and remote control (a full system 1, as illustrated in FIG. 1), other vents/rooms may have the register configured with the motor assembly 340, but not use the remote-transmitter system 310 (for potential future upgrade without having the need and inconvenience of later installation of motor-receiver-controller assembly 340 to register assembly 100), and other vents/rooms may have only the register without motor-receiver-controller assembly 340 attached (the register being available for a standard manual operation).

In the example illustration of FIG. 1, register 100 is shown with a housing assembly 110. Housing assembly 110 forms a frame for holding the register assembly members and provides for placement of the register assembly members into a heating or air conditioning vent opening. For example, a heating or air conditioning system will have duct work that terminates in a boot that provides an opening into a room for placement of a vent or register-vent assembly. Housing assembly 110 includes a first sliding housing member 112 and a second sliding housing member 114. As shown in FIG. 1, for example, sliding housing member 112 is a 3-sided frame having an end and two sides, the opposite end being open. The boxed end of first sliding housing member 112 has a receiving cavity for housing the motor-receiver-controller assembly 340. Similarly, sliding housing member 114 is a 3-sided frame having an end and two sides, the opposite end being open. The boxed end of second sliding housing member 114 has a compartment to hold a gear assembly (to be detailed in FIG. 2 and FIG. 5). The two sides of sliding housing member 112 are sized and shaped to conformably fit and receive the two sides of sliding housing member 114, thus forming a 4-sided box frame. The conformable fit of the two sides of sliding housing member 112 with the two sides of sliding housing member 114 are slidable, allowing for the lengthwise portion comprising the sides to be adjustable to a range of lengths. In this example, the ends of sliding housing member 112 and sliding housing member 114 are of fixed width. Housing assembly 110 thus has the ability to be adjusted into a variety of sizes in the lengthwise direction. Thus, a means for sizing the regulating element is provided. In this example, the regulating element includes a housing and the housing includes two fixed-width sides and two lengthwise adjustable sides. The fixed width sides have a means for receiving one or more slats, for example, louvers.

In the example illustration of FIG. 1, register 100 is shown with an adjustable sliding louver assembly 150. Register assembly 100 provides means for obstructing airflow through the heating or air conditioning opening by receiving onto housing assembly 110, in one example, slats positioned across the opening. In one example, Louver assembly 150 includes one or more lengthwise adjustable slats. The slats are adjustable in length to conform to the adjusted length of housing assembly 110. In one example, the slats are positioned lengthwise across the opening. In one example, the slats are rotatably engaged to the fixed width sides of sliding housing members 112, 114 of adjustable housing assembly 110.

In another example, not illustrated, the slats or louvers are of fixed length, with the fixed length conforming to the adjusted length of the housing assembly. In this example, the fixed length slats or louvers are selected and attached to the housing assembly after the housing assembly is adjusted to the desired length.

In the example illustration of FIG. 1, motor-receiver-controller assembly 340 is configured to receive a removable power pack assembly 380. Power pack assembly 380 is sized and shaped to receive batteries 381.

In the example illustration of FIG. 1, a grill assembly 200 includes three removably connecting members: a first end grill member 210, a second end grill member 240, and a center grill member 260. Center grill member 260 disposes upon first end grill member 210 and upon second end grill member 240. The grill assembly 200 is adjustable in length, adjustable by setting the amount of overlap when center grill member 260 is attached to the end grill members 210, 240. In this way, grill assembly 200 conforms to the length necessary to cover the adjusted length of register assembly 100.

FIG. 2 illustrates a 3-D perspective assembled view of an example of the Register Assembly 100 configured for manual operation. As previously described, housing assembly 110 includes first sliding housing member 112 and a second sliding housing member 114. As illustrated, first sliding housing member 112 is sized and shaped as an outer member, being slidingly engageable to receive the sides of second sliding member 114, second sliding member 114 being an inner member in this example. In another example, one of sliding housing member 112 or 114 is the inner member and the other is the outer member. In other examples, other sliding engagement configurations are possible for the first and second housing members 112 and 114.

Along the sides of first housing member 112 are one or more lengthwise wall locking detents 113 for receiving corresponding lengthwise wall locking male tab 115 disposed on the sides of second housing member 114. In the illustrated example, detent 113 is a hole. In the illustrated example, male tab 115 is a protruding member of the side of second housing member 114, protruding inward towards detents 113. As the male tab 115 slides across a detent 113, male tab 115 acts as a locking member to secure the position of sliding housing member 114 into sliding housing member 112. In other examples, the placement of male tabs and corresponding detents can be reversed on the corresponding first and second housing members. In example, lengthwise wall locking detents 113 and tabs 115 are positioned and arranged to conform to selected register lengths, enabling register assembly 100 to “lock” into one or more register opening lengths. In further example, lengthwise wall locking detents 113 and tabs 115 are positioned and arranged to conform to selected register lengths, enabling register assembly 100 to “lock” into one or more “standard” opening lengths. In further example, “standard” opening lengths include spacing of the locking detents 113 having a spacing of one inch between each detent 113. In one example, end compression tabs 119 or springs disposed on the ends of outside of register housing assembly 110 (the ends of each of sliding housing members 112, 114) and will compensate for intervals that are less than one inch (or the selected spacing) between the detents. Thus, the end compression tabs or springs in combination with the detent spacing will enable use of the register assembly 100 across a full range of adjusted lengths. In one example, detents 113 are positioned and arranged to provide for one or more adjustable lengths for the register assembly of 8″, 10″, 12″, 14″, 16″. Compression tabs 119 or springs compensate to allow for fitting of lengths that fall in between the locking positions allowed for by the positioning of the detents, such as, by example, 9″, 11″, 13″, 15″, enabling fitting across the full range of lengths.

As illustrated in the example of FIG. 2, one or more compression spring tabs 119 are disposed on the outer surfaces of first and/or second housing members 112, 114. In a preferred example, four compression spring tabs 119 are disposed, two on the end corners of first housing member 112 and two on the end corners of second housing member 114. In one example, compression spring tabs 119 are metallic tabs tempered with an outward bend so as to hold pressure on the end walls of register assembly 100 when the register assembly is inserted into a boot or duct opening. In another example, the tabs are made of molded plastic as an integrated part of the housing member. In one example, a tab 121 with a screw hole disposed on the fixed width end of housing member 112 (and/or housing member 114, not illustrated) are provided to allow for sheet metal (or other fastening means) screws to be driven through the register assembly and into the boot or duct opening or wall/ceiling adjacent to the opening.

As illustrated in the example of FIG. 2, a tab 122 is disposed on one side of first housing member 112 for receiving an open hinge. A second tab 124 is dispose on the adjoining side of second housing member 114 for receiving a corresponding second open hinge. The open hinge is disposed, in one example, on grill assembly 200 (illustrated in FIG. 8).

As illustrated in the example of FIG. 2, a cavity 117 is disposed in first housing member 112 for fittingly receiving the motor-receiver-controller assembly 340. In one example, cavity 117 is formed from the end of first housing member 112. In this example, cavity 117 enables “snap in” and “snap out” assembly of the motor-receiver-controller assembly 340 to the register assembly 100. In one example, a slot (not illustrated) is disposed in first housing member 112 for receiving an urging locking tab (not illustrated) of motor-receiver-controller assembly 340, as part of the structural features that enable motor-receiver-controller assembly 340 to be easily “snapped in” or “snapped-out” by hand or with a small blade, such as the blade of a screwdriver.

As illustrated in the example of FIG. 2, the adjustable sliding louver assembly 150 includes an outer sliding louver 152 and an inner sliding louver 154. As illustrated, outer sliding louver member 152 is sized and shaped as an outer member, being slidingly engageable to fit onto the sides of inner sliding louver member 154, inner sliding louver member 154 being an inner member in this example. In another example, one of sliding louver member 152 or 154 is the inner member and the other is the outer member. In other examples, other sliding engagement configurations are possible for the sliding louver members 152 and 154.

In the illustrated example, one end of outer sliding louver 152 is rotatably connected to the inside end of first housing member 112 and one end of inner sliding louver 154 is rotatably connected to the inside end of second housing member 114. A pivot axis pin 153 (illustrated in FIG. 3) is disposed on that end of outer sliding louver 152, forming an axis along the longitudinal direction of the louver slat. Pin 153 is connected to the end of first housing member 112 to form a rotational engagement of the louver slat. In like manner, a pivot axis pin 155 (illustrated in FIG. 3) is disposed on that end of inner sliding louver 154, on the axis along the longitudinal direction of the louver slat. Pin 155 is connected to the end of second housing member 114 to form a rotational engagement of the louver slat. The opposite ends from the pins of outer sliding louver 152 and inner sliding louver 154 are slidingly engaged to each other, forming a louver or slat whose length is adjustable in the lengthwise direction.

As illustrated in FIG. 2, a gear assembly 160 is disposed in the end of second housing member 114. Gear assembly 160 gang to the slats or louvers which, in this illustrated example, is adjustable sliding louver assembly 150.

FIG. 3 illustrates a 3-D perspective exploded view of an example of Register Assembly 100 configured for manual operation, with component detail.

As previously described, housing assembly 110 includes first sliding housing member 112 and a second sliding housing member 114.

In the illustrated example, lengthwise wall locking detents 113 along the sides of first housing member 112 for receiving corresponding lengthwise wall locking male tab 115 disposed on the sides of second housing member 114. In one example, detents 113 and male tab 115 provide a means for removably affixing register housing assembly 110 into one or more pre-selected lengths. There are other equivalent means for removably affixing the length of the register housing. As previously indicated, the means for affixing the length of the register housing assembly include positioning and arranging the detents or equivalent to conform to selected register lengths, enabling the register assembly to “lock” into one or more “standard” opening lengths.

As illustrated in FIG. 3, a gear assembly 160 is disposed in the end of second housing member 114. In one example, the end of second housing member 114 includes an internal wall 116, forming a pivot axis box 118 for receiving pins 155. Pivot axis box 118 contains and holds gear assembly 160. Pins 155 are disposed into wall 116 for connection to gear assembly 160. A controlling gear 163 of gear assembly 160 protrudes from pivot axis box 118, acting as a lever to provide manual rotational control of the louvers.

As illustrated in the example of FIG. 3, a cavity 117 is disposed in first housing member 112 for fittingly receiving the motor-receiver-controller assembly 340. In this example, cavity 117 enables “snap in” and “snap out” assembly of the motor-receiver-controller assembly 340 to the register assembly 100. In one example, a slot (not illustrated) is disposed in first housing member 112 for receiving an urging locking tab (not illustrated) of motor-receiver-controller assembly 340, as part of the structural features that enable motor-receiver-controller assembly 340 to be easily “snapped in” or “snapped-out” by hand or with a small blade, such as the blade of a screwdriver.

Compression tabs 119 are shown disposed on the end corners of housing member 112. A screw hole tab 121 is disposed on the end of housing member 112.

As illustrated in the example of FIG. 3, a tab 122 is disposed on one side of first housing member 112 for receiving an open hinge. A second tab 124 is disposed on the adjoining side of second housing member 114 for receiving a corresponding second open hinge. Tabs 122, 124 provide a means for swinging grill assembly 200 into an open or closed position. This enables additional ease in replacing a grill assembly filter and/or replacing power pack assembly 380 and/or associated batteries 381. In one example, an opening 126 on the top surface of the end of housing 112 provides an access into cavity 117 for disposing or removing power pack assembly 380.

In one example, an opening 127 is disposed on the top surface of the end of housing 112 to enable visibility of an LED indicator 354 (illustrated in FIG. 4) from motor-controller-receiver assembly 340.

As illustrated in the example of FIG. 3, the adjustable sliding louver assembly 150 includes an outer sliding louver 152 and an inner sliding louver 154. As illustrated, outer sliding louver member 152 is sized and shaped as an outer member, being slidingly engageable to fit onto the sides of inner sliding louver member 154, inner sliding louver member 154 being an inner member in this example. In another example, one of sliding louver member 152 or 154 is the inner member and the other is the outer member. In other examples, other sliding engagement configurations are possible for the sliding louver members 152 and 154.

In the illustrated example, outer sliding louver 152 is rotatably connected to the inside end of first housing member 112 and inner sliding louver 154 is rotatably connected to the inside end of second housing member 114, in one example to inner wall 116. A pivot axis pin 153 is disposed on one end of outer sliding louver 152, forming an axis along the longitudinal direction of the louver slat. Pin 153 is connected to the end of first housing member 112 to form a rotational pivot engagement of the louver slat. In like manner, a pivot axis pin 155 is disposed on one end of inner sliding louver 154, on the axis along the longitudinal direction of the louver slat. Pin 155 is connected to the end of second housing member 114 (inner wall 116) to form a rotational pivot engagement of the louver slat. The opposite ends from the pins of outer sliding louver 152 and inner sliding louver 154 are slidingly engaged to each other, forming a louver or slat whose length is adjustable in the lengthwise direction. Thus, louver assembly 150 is rotatably connecting to housing member 112 and housing member 114.

In one example, a drive shaft member 159 protrudes from the pin 153 of one of outer sliding louver 152 for the purpose of receiving rotational torque from motor-receiver-controller assembly 340. In one example, drive shaft member 159 is conformably keyed for connecting or coupling the driving shaft from motor-receiver-controller assembly 340.

In one example, a reinforcing ridge 157 is disposed along an axis in the longitudinal direction of the sliding louvers 152, 154. In one example, pin 153 and/or pin 155 extends from reinforcing ridge 157 of respective sliding louver 152, 154.

FIG. 4 illustrates a 3-D perspective exploded view of an example of first housing member 112 with motor-controller-receiver assembly 340.

As illustrated in the example of FIG. 4, detents 113 are disposed on the sliding sides of first housing member 112. A cavity 117 is disposed in the boxed end of first housing member 112 for fittingly receiving the motor-receiver-controller assembly 340. Compression tabs 119 are shown disposed on the end corners of housing member 112. A screw hole tab 121 is disposed on the end of housing member 112.

As illustrated in the example of FIG. 4, a receiving tab 122 is disposed on one side of first housing member 112 for receiving an open hinge 213 (illustrated in FIG. 7). In one example, an opening 126 on the top surface of the end of housing 112 provides an access into cavity 117 for disposing or removing power pack assembly 380.

In one example, an opening 127 is disposed on the top surface of the end of housing 112 to enable visibility of an LED indicator 354 from motor-controller-receiver assembly 340.

In one example, an inner wall 128 traverses the width of housing member 112 and serves to receive pins 153 of the louvers 152 (illustrated in FIG. 3), forming a back wall to cavity 117. In the inner wall 128 of cavity 117 is a hole 129 for receiving the through pin 153 (illustrated in FIG. 3) and drive shaft member 159 (illustrated in FIG. 3).

Bushing 347 is keyed for receiving drive shaft member 159 (illustrated in FIG. 3) and the shaft 345 of geared stepper motor 346. Between the shaft 345 of geared stepper motor 346 and bushing 347 is an assembly housing 341 for motor-receiver-controller assembly 340. The shaft 345 of geared stepper motor 346 therefore passes through a hole in the back wall of assembly housing 341 to couple or connect to bushing 347. In a like manner, drive shaft member 159 (illustrated in FIG. 3) passes through hole 129 of inner wall 128 to couple or connect to the opposite side of bushing 347.

In the example of FIG. 4, assembly housing 341 includes two compartments, one compartment 356 to receive and contain power pack assembly 380 and one compartment 357 to contain the stepper motor 346 and microprocessor 350. In one example, the hole for passing drive shaft member 159 (illustrated in FIG. 3) is therefore on the back wall of compartment 357.

In one example, assembly housing 341 is made of two interlocking, clamshell pieces, forming the complete housing for the motor-receiver-controller assembly 340. An opening 355 corresponds to opening 126 of the sliding housing 112 and is disposed on the top side of assembly housing 341. Opening 355 opens into the compartment 356 for receiving power pack assembly 380. The matched openings 126 and 355 enable power pack assembly 380 to be inserted or removed from the top side of sliding housing member 112 when motor-receiver-controller assembly 340 is installed into cavity 117 of housing member 112 of register assembly 100.

Compartment 357, as previously discussed, contains stepper motor 346. In one example, microprocessor assembly 350 is disposed in compartment 357 and electrically connected to electrical contacts disposed in compartment 356. Microprocessor assembly 350 is a programmed controller to actuate stepper motor 346. Microprocessor assembly 350 includes a radio frequency receiver and antenna to receive commands from remote-transmitter-assembly 310. In one example, the receiver uses non-RF means, such as infrared. LED indicator 354 is in electrical communication with microprocessor assembly 350. An opening 358 on the top surface of assembly housing 341 enables the light from LED indicator 354 to pass through opening 127 of sliding housing 112.

Batteries 381 are insertable into power pack assembly 380. Electrical contact surface 383 in power pack assembly 380 electrically connects the batteries 381 to transfer the electrical connection to the outside surface of power pack assembly 380 for receiving inside compartment 356 and ultimate electrical connection to microprocessor assembly 350.

FIG. 5 illustrates a 3-D perspective exploded view of an example of second housing member 114, with component detail. Male tabs 115 are disposed on the sides of second housing member 114. As illustrated in this example, male tab 115 is a protruding member of the side of second sliding housing member 114, protruding inward towards the detents 113 on the outer wall of the side of first sliding housing member 112.

Compression spring tab 119 is shown disposed, two on the end corner of second housing member 114.

Receiving tab 124 is disposed on the adjoining side of second housing member 114 for receiving a corresponding second open hinge 243 (illustrated in FIG. 7).

In one example the end of second housing member 114 includes an internal wall 116, forming a pivot axis box 118 for receiving pins 155 (illustrated on FIG. 3). Pivot axis box 118 contains and holds gear assembly 160. Pins 155 (illustrated on FIG. 3) are disposed into wall 116 for connection to gear assembly 160. Within pivot axis box 118 are disposed louver gears 161 whose axes are aligned to receive pins 155 (illustrated on FIG. 3) through wall 116. A louver gear 161 is affixed to each pivot axis pin 155 from each of inner louvers 154 (illustrated on FIG. 3). A ganging gear 162 is axially disposed on the wall 116 in axis box 118 of second housing member 114 and rotatably pivots on its axis. Ganging gear 162 couples in geared arrangement with two louver gears 161. A controlling gear 163 is axially disposed on a ganging gear 162 and rotatably pivots on its axis to operate as a lever. Controlling gear 163 of gear assembly 160 protrudes from pivot axis box 118 to provide leverage for manual rotational control of the louvers.

Gear assembly 160 and associated members provide a means for manually, by hand, obstructing the airflow in varying degrees. This is accomplished, in this example, by moving the louvers or slats in unison, into various positions of open, partially open, or closed. There are other equivalent means for manually obstructing the airflow.

FIG. 6 illustrates a 3-D perspective outward side view of an example of Grill Assembly 200, exploded without overlap of assembly components. In the illustrated example, Grill Assembly 200 includes three removably connecting members: a first end grill member 210, a second end grill member 240, and a center grill member 260 that disposes upon first end grill member 210 and upon second end grill member 240.

First end grill member 210 has an outward side 212 that will be at least partially visible to users when Grill Assembly 200 is attached to Register Assembly 100. Air dispersion openings 218 are disposed through first end grill member 210 to allow air to flow from the inward side of first end grill member 210 to the outward side 212. In one example, deflection fins 219 are oriented to direct the airflow in a preferred direction, such as sideways from the boot or duct opening. At least a portion of the outward side 212 surface of first end grill member 210 includes an engagement surface 221 for engagingly receiving an engagement surface portion of an inward side of center grill member 260. In one example, an opening 223 is disposed on first end grill member 210 in conformal alignment to an underlying LED 354 that is contained in motor-receiver-controller assembly 340 (as illustrated in FIG. 4).

Second end grill member 240 has an outward side 242 that will be at least partially visible to users when Grill Assembly 200 is attached to Register Assembly 100. Air dispersion openings 248 are disposed through second end grill member 240 to allow air to flow from the inward side of second end grill member 240 to the outward side 242. In one example, deflection fins 249 are oriented to direct the airflow in a preferred direction, such as sideways from the boot or duct opening. At least a portion of the outward side 242 surface of second end grill member 240 includes an engagement surface 251 for engagingly receiving an engagement surface portion of an inward side of center grill member 260. In one example, an opening 245 is disposed on second end grill member 240 in conformal alignment to underlying controlling gear 163 (or manual lever) that is connected to or a part of gear assembly 160 (as illustrated in FIG. 5).

Center grill member 260 has an outward side 262 that will be visible to users when Grill Assembly 200 is attached to Register Assembly 100. Air dispersion openings 268 are disposed through center grill member 260 to allow air to flow from the inward side of center grill member 260 to the outward side 262. When center grill member 260 is disposed on portions of end grill members 210, 240 the air dispersion openings 218, 248, 268 will overlap sufficiently for air to flow from the register housing 100, if any, through the grill assembly 200 and outward into the subject room. In one example, deflection fins 269 are oriented to direct the airflow in a preferred direction(s), such as sideways from the boot or duct opening and in respective conformance to the directions provided by fins 219, 249. At least portions of the inward surface of center grill member 260 includes engagement surfaces for engagingly receiving engagement surface portions 221, 251 of outward sides of grill members 210, 240.

The outwards sides 212, 242, 262 of grill members 210, 240, 260 form the outwardly visible portion of grill assembly 200 and therefore contain the majority of the visible surface for discretionary ornamental design. In one example, alternate ornamentally embellished grills are provided to meet the preferences of the user.

FIG. 7 illustrates a 3-D perspective inward side view of an example of Grill Assembly 200, exploded without overlap of assembly components. In the illustrated example, Grill Assembly 200 includes three removably connecting members: a first end grill member 210, a second end grill member 240, and a center grill member 260 that disposes upon first end grill member 210 and upon second end grill member 240.

First end grill member 210 has an inward side 211 that will be visible to users when Grill Assembly 200 is opened from or otherwise detached from Register Assembly 100. Inward side 211 is not generally visible to users when the system is in use. Air dispersion openings 218 are disposed through first end grill member 210 to allow air to flow from the inward side 211 of first end grill member 210 to the outward side 212 (illustrated in FIG. 6). In one example, deflection fins 219 are oriented to direct the airflow in a preferred direction, such as sideways from the boot or duct opening. In one example, an opening 223 is disposed on first end grill member 210 in conformal alignment to an underlying LED 354 that is contained in motor-receiver-controller assembly 340 (as illustrated in FIG. 4).

An open hinge 213 is disposed on inward side 211 proximate to an edge to conform with a receiving tab 122 on first sliding housing member 112 (as illustrated on FIG. 4). In one example, a means for clasping is provided, to open and shut the grill assembly 200 from/to register assembly 100. In one example, a clasp is disposed on inward side 211 proximate to the opposite edge to conform to a corresponding clasping surface on sliding housing member 112. In one example, the edge along the length of the opposite side is shaped to “snap” onto the edge of sliding housing member 112. In one example of a means for clasping, a small magnet is used to hold the grill assembly 200 to the register assembly 100.

In one example, one or more channel ledges 216 are disposed on inward side 211 proximate to the edges, for receiving a filter. The channel ledges are an example of receiving members disposed on the inward side of the end grill member for urgedly receiving the filter element.

Second end grill member 240 has an inward side 241 that will be visible to users when Grill Assembly 200 is opened from or otherwise detached from Register Assembly 100. Inward side 241 is not generally visible to users when the system is in use. Air dispersion openings 248 are disposed through second end grill member 240 to allow air to flow from the inward side of second end grill member 240 to the outward side 242. In one example, deflection fins 249 are oriented to direct the airflow in a preferred direction, such as sideways from the boot or duct opening. At least a portion of the outward side 242 surface of second end grill member 240 includes an engagement surface 251 for engagingly receiving an engagement surface portion of an inward side of center grill member 260. In one example, an opening 245 is disposed on second end grill member 240 in conformal alignment to underlying controlling gear 163 (or manual lever) that is connected to or a part of gear assembly 160 (as illustrated in FIG. 5).

An open hinge 243 is disposed on inward side 241 proximate to an edge to conform with a receiving tab 124 on second sliding housing member 114 (as illustrated in FIG. 5 and FIG. 8). In one example, a means for clasping is provided, to open and shut the grill assembly 200 from/to register assembly 100. In one example, a clasp is disposed on inward side 241 proximate to the opposite edge to conform to a corresponding clasping surface on sliding housing member 114. In one example, the edge along the length of the opposite side is shaped to “snap” onto the edge of sliding housing member 114.

In one example, one or more channel ledges 246 are disposed on inward side 241 proximate to the edges, for receiving a filter. Receiving members disposed on the inward side of the end grill member for urgedly receiving the filter element.

Center grill member 260 has an inward side 261 that may be partially visible to users when Grill Assembly 200 is opened from or otherwise detached from Register Assembly 100. Inward side 261 is not generally visible to users when the system is in use. Air dispersion openings 268 are disposed through center end grill member 240 to allow air to flow from the inward side 261 of center grill member 260 to the outward side 262 (illustrated in FIG. 6). When center grill member 260 is disposed on portions of end grill members 210, 240 the air dispersion openings 218, 248, 268 will overlap sufficiently for air to flow from the register housing 100, if any, through the grill assembly 200 and outward into the subject room. In one example, deflection fins 269 are oriented to direct the airflow in a preferred direction(s), such as sideways from the boot or duct opening and in respective conformance to the directions provided by fins 219, 249. At least portions of the inward surface 261 of center grill member 260 includes engagement surfaces 271 for engagingly receiving engagement surface portions 221, 251 of outward sides 212, 242 of grill members 210, 240.

In one example, lengthwise adjustable grill assembly 200 has receiving members disposed on the inward side of the center grill member for urgingly receiving a filter element.

In one example, lengthwise adjustable grill assembly 200 has a material composition of the grill assembly such that in an adjusted length it has a compressive strength on the outward side of the end and center members equal to or exceeding three hundred pounds. This allows for use of the grill assembly to cover a vent or register on the floor and withstand the weight of furniture or people walking on the grill.

In examples, the lengthwise adjustable grill assembly 200 includes a lengthwise sizeable filter element, the filter element marked widthwise at a plurality of lengths for sizing to conform to the adjusted length of the adjustable grill assembly. In one example, a filter 290 is dimensioned to fit into an adjusted size of grill assembly 200. In one example, filter 290 is inserted beneath channels 216, 246. Since the grill assembly 200 may be set to various lengths, depending on the placement of center grill member 260 upon end grill members 210, 240, in one example, graduations 282 are marked on filter 290 at pre-selected lengths. In one example, graduations 282 are marked on filter 290. In one example, graduations 282 are perforated on filter 290 for ease in sizing the length of filter 290. In one example, graduations 282 are scored on filter 290. In examples, thus, the filter is further perforated, scored, or marked at one or more standard lengths for cutting or separating to desired length before affixing to grill assembly.

It can be appreciated from the foregoing description, that the length-adjustable grill member avoids exposing screws on the outward surface. In example, the means for attaching the grill to the register are disposed on the inward surface and not on the outward surface. This increases the ornamental appeal to the end user. In example, the grill assembly, being separable from the register and no tools are needed to remove, allows for manufacturing a variety of ornamental designs for the grill assembly. In example, the means for attaching enables opening of the grill without screws and without removing the register, allowing for ease in hand washing and/or filter replacement. In example, the open hinge means for attachment enables opening and removal of the grill assembly for separate washing in a sink or dishwasher. In one example, scented filters are disposed in the grill assembly.

In one example, the grill assembly is removably disposed onto the register housing. Since the grill assembly is the outwardly visible piece, it contains the majority of the discretionary ornamental design. In one example, alternate ornamentally embellished grills are available to meet the preferences of the user. In one example, four popular grill ornamentation designs are provided, in one example, a contemporary and a colonial design are provided.

In one example, the grill assembly housing provides a recess on the inward side of the grill, the recess configured for receiving a filter. The filter may be urged into the recess.

In one example, the grill assembly housing being removable can be replaced when no longer aesthetically pleasing, such as aging of the plastic or paint or change in desired style. In one example, the grill assembly housing is composed of a material that is paintable.

FIG. 8 illustrates a side view of an example of Grill Assembly 200, showing a partially open positioning of the assembly on the register assembly 100. FIG. 8 illustrates the end side of first sliding housing member 112 of the register assembly 100, which reveals either cavity 117 or, if motor-receiver-controller assembly 340 is installed, will show the front face of assembly housing 341. Receiving tab 122 for open hinge 213 is disposed, in this example, on the upper right side edge of sliding housing member 112. In this way, grill assembly 200 rotates open or closed relative to the top surface of register assembly 100. Arrow 800 indicates the direction of rotation of grill assembly 200 as it is opened from its closed position on top of register assembly 100.

FIG. 9 illustrates a 3-D perspective exploded view of an example of remote-transmitter assembly 310. Remote-transmitter assembly 310 is contained in an assembly housing 311 having a back side 313. Assembly housing 311 is structurally dimensioned for either hand held use or for attachment to a wall surface, in one preferred example, attached to a wall surface adjacent to a light switch. The front facing surface of assembly housing 311 provides access to the control members and display members. In one example, an open-close switch 312 provides an up and down button for sending an “open” or “close” signal ultimately to the motor-receiver-controller assembly 340. Each press of the “open” or “close” button will initiate a signal to request partially opening or closing the louver assembly 150 by an incremental amount. This is accomplished in this example by electrically connecting switch 312 to a microcontroller microprocessor 324 on controller board 320, the controller board 320 disposed inside the assembly housing 311. Microprocessor 324 is electrically connected to an array of status indicator LEDs 314 and to an RF transmitter assembly 326. In one example, the transmitter uses non-RF means, such as infrared. Status indicator LEDs 314 indicate the incremental position of the louver that the user desires. In example, if (more) “open” is pressed on open-close switch 312, then the next higher LED is lit by microprocessor 324. If (more) “close” is pressed on open-close switch 312, then the next lower LED is lit by the microprocessor 324. In one example, the lowest LED of status indicator LEDs 314 is red (indicating a desire that the register/vent be closed), and the other four LEDs are green (with the top one indicating a desire for the register/vent to be fully open). Power is provided by a battery contained in a battery compartment 330. In one example, a battery power regulator 332 maintains voltage regulation to microprocessor 324 and RF transmitter assembly 326. In one example, the electronic components are positioned and arranged together onto the controller board 320, as illustrated in this Figure. In one example, on the back side 313 of assembly housing 311 is a peel-and-stick adhesive surface 334 for attaching remote-transmitter assembly 310 to a wall or other surface.

In one example, an open-close switch is a linear sliding potentiometer (illustrated in FIG. 11), touch plate, or equivalent user-input device. Corresponding connection to the microcontroller microprocessor 324, along with microprocessor programming, enable the movement of the sliding potentiometer to be converted into signals to request partially opening or closing the louver assembly 150 by an incremental amount, replicating a manual movement.

An LCD readout 328 is disposed on the facing surface of assembly housing 311 to provide a user with a readout of the measured temperature. In one example, LCD readout 328 is configured to act as a passive reporting thermometer. In one example, LCD readout 328 is powered by a battery. In one example, LCD readout 328 includes a temperature sensor and processor so that the LCD readout will display the current measured temperature. In another example, a temperature sensor 322 is disposed in remote-transmitter assembly 310. The sensor is used by a microprocessor (in one example, microprocessor 324) to determine the temperature. The temperature information is then sent by the microprocessor to the electrically connected LCD readout 328. Thus, LCD readout 328 acts as a passive reporting thermometer. Thus, the actual room temperature is measured and displayed.

Special note is made of an unusual example of the present invention. Some remote controls in the art include a thermostat, especially in the case of split A/C systems, enabling the user to set the remote to a specific desired temperature to turn on or off the air conditioning. The present inventor has realized that some, if not all, users do not necessarily care about setting the temperature or even want to try to figure out what the numeric temperature has to be in order for a room to feel comfortable. Setting a temperature, and the corresponding required thermostatic controls and two-way communication, greatly complicate and add to the expense of the air conditioning system. In reality, the inventor has discovered, the user merely wishes to open or close the register/vent by some incremental amount—independent of a thermostat and independent of numeric analysis—and would be greatly satisfied by simply knowing a temperature reading along with a semi-quantitative estimate of the amount the register/vent is incrementally open or closed. This enables a solution that requires only a one-way transmission from the remote to the receiving register/vent, greatly reducing cost and complexity. Further, the power requirements of the register/vent are enormously reduced, being that the register/vent is not required to open or close or adjust with every cycle of the furnace or air conditioner. Networking, central processing, neural networks, and other cost and labor intensive options are avoided. Thus, discovery of the problem and solving with this seemingly simple improvement, of dispensing with a thermostat while providing a passive thermometer, revealed significant unexpected and unobvious results and benefits.

In one example, remote-transmitter assembly 310 provides a limited number of louver positions. In one example, an open position and a closed position and one or more intermediate positions are provided. In one example, three positions between open and closed are provided, for a total of five positions.

In one example, upon detecting a low battery condition, remote-transmitter assembly 310 sends a signal to fully open the louvers and starts blinking the full-open LED.

FIG. 10 illustrates a flowchart showing an example of operation of the register system 1.

Step 1001, Unpowered initial state: the louvers of the louver assembly 150 are in an open position. In one example, bushing 347 and drive shaft member 159 are keyed such that motor-receiver-controller assembly 340 is positioned in an initially open state for the louvers.

Step 1001A, Upon powering the motor-receiver-controller assembly 340: radio frequency receiver of microprocessor assembly 350 starts listening; microprocessor 350 drives stepper motor 346 enough to fully open louver assembly 150.

Step 1002, Upon powering the remote-transmitter assembly 310: microprocessor 324 sends a “fully open” signal via RF transmitter 326; in one example, microprocessor 324 reads temperature sensor 322 and displays temperature to LCD readout 328.

Step 1003, Upon pressing open-close switch 312: transmitter 326 sends either an “open” or a “close” signal; indicates the position of the louver on status indicator LED 314. In one example, if “open” is pressed, then the next higher LED is lit by microprocessor 324. If “close” is pressed, then the next lower LED is lit by the microprocessor 324. In one example, the lowest LED is red [indicating closed], the other four LED's are green [top one lit indicating fully open].

Step 1004, the motor-receiver-controller assembly 340 hears the “open” or a “close” signal: microprocessor 350 temporarily flashes LED indicator 354; microprocessor 350 drives stepper motor 346 by a predetermined amount in order to, by an increment, open or close louver assembly 150.

Step 1004A, the motor-receiver-controller assembly 340 hears the “fully open” signal: microprocessor 350 temporarily flashes LED indicator 354; microprocessor 350 drives stepper motor 346 enough to fully open louver assembly 150.

In one example, the louver positioning adjustment buttons on the remote controller send a signal to the adjustable register to position the louvers into open, closed, and intermediate positions. In one example, the adjustable register responds with one of five positions of the louvers, namely, in one example, “open”, “closed”, 25% open, 50% open, 75% open. In one example, 25% open is measured in terms of amount of rotation of the louver from the fully open to the fully closed positions. In one example, this would be 22.5 degrees per position.

Turning now to additional examples of alternate configurations, should the range of desired adjustable lengths be sufficiently large, then the register housing may have more than two sliding sections for each of the adjustable length sides. This situation arises in the case of the range of lengthwise openings being greater than (something a bit less than) twice the length of the smallest adjustable length. In one example, the multiple sliding sections telescope. In another example, the adjustable length slats also comprise two or more sliding sections.

FIG. 11 is a perspective view of an example of using the battery operated remote controlled micro transmitter with a linear sliding potentiometer and permanently mounted digital thermometer affixed to the plate assembly with the ability of a self-adhesive strip for tool less mounting included. As illustrated in FIG. 11, a micro controlled linear sliding potentiometer transmitter is designed to replicate the manual movement associated with prior art devices that required manually moving the typical lever attached to the louver system mounted in the commonly used grill system. The present example allows for remotely replicating the manual lever movement of said louvers in a full range of positions controlling the volume of air flow rather than as previously mentioned in other prior art, simply commanding louvers to adjust in a fully open or fully close positions with no provision for interim adjustments of air flow volume. The said linear sliding potentiometer transmitter as shown in FIG. 11 is designed to be conveniently adjusted at anytime conditions change within the room. In particular, FIG. 11 illustrates a typical light switch and plate 1 adjacent to a main remote control signal transmitting panel 2, disposed on a wall 9. A digital thermometer room temperature display 3 is disposed on the facing surface of panel 2. A battery access cover plate 4 is disposed on the side. A travel adjustment graphic indicator 5 is disposed on the main face. A sliding potentiometer dial 6 serves to remotely replicate the controlling lever action of the main register. The main control panel 2 houses a micro controller, transmitter and battery powered devices. The hand of a user 8 is shown for reference.

FIG. 12 provides a perspective view of an example using six (6) main interlocking units that, when together make up the fully adjustable grill assembly with separate sliding adjustable louver-fin assemblies. In one example, the louver-fins are fixed. In this example, grill assembly 20 is purposely constructed such in a manner to both adjust in length and width to accommodate said standard air duct boot compartment boxes. Adjustable grill 20 is a cover plate with louver-fins and forms a length and width adjustable frame housing for the grill assembly. In one example, the six frame adjustable grill assembly is formed using a plurality of receiving sliding adjustable grill cover plate louvers 21, a Center frame 21A for receiving sliding louvers, Lower recessed sliding louvers 21B, an Upper level receiver frame 21C for sliding recessed adjustable louvers, Lower level sliding recessed adjustable frame and louvers 22A, Lower recessed sliding louver 22B, Lower level sliding center recessed frame 23A for supporting adjustable frame and louvers, Lower center frame recessed sliding louver 23B, Lower level sliding recessed adjustable frame and louvers 24A, Upper level receiver frame 24B for sliding recessed adjustable lower level frame and louver. In one example, attachment points 25 are used to install the grill cover plate to main register. Continuing, Upper level receiver frame 26B is disposed for receiving sliding recessed adjustable lower level frame and louver, Upper level center receiver frame 27B is disposed for supporting sliding recessed adjustable lower level frame and louver, and Upper level receiver frame 28 for receiving sliding recessed adjustable lower level frame and louver. The assembly forms a frame area 29. Arrows 30 indicate the directional adjustability of main complete register grill cover plate louvers and adjustable frame housing.

FIG. 13 illustrates a bottom view perspective of an example of a complete main register assembly and featured components as seen from the perspective of a mounted unit installed in a ceiling boot box. Upper level receiver louver blades 31 for sliding recessed adjustable lower louver blade are disposed in the assembly along with Lower level sliding recessed adjustable louver blades 32. Main register compression corner spring frame housing 33 forms part of the frame for the assembly. A Longitudinal recessed support frame 34 with attached spring snap button for securing longitudinal frame adjustments attaches frame 33 to Main longitudinal receiver support frame 38. Main longitudinal receiver support frame 38 has pre-positioned receiver holes for securing longitudinal frame adjustments. A Latitudinal receiver support frame 36 with attached spring snap button opening hole for securing longitudinal frame adjustments attaches to Main longitudinal receiver support frame 38. Latitudinal recessed support frame 37 with attached spring snap button for securing latitudinal frame adjustments connects Latitudinal receiver support frame 36 to a second Main longitudinal receiver support frame 38. In one example, an Easy access battery compartment cover 35 for replacing batteries when needed is disposed on the assembly, on one Latitudinal recessed support frame 37. In one example, a Housing compartment 39 for micro receiver device, electrical, mechanical and louver forced generating means is disposed on the assembly, on the Main register compression corner spring frame housing 33. Pivoting points 40 are centrally positioned in the first ends of the louver and are rotatable within the circular recess.

In one example, a Removable cartridge housing louver compartment 41 including micro receiver device, electrical, mechanical and louver forced generating means is disposed in the assembly. Thus presented is a bottom perspective view 42 of the main register's components prior to boot installation.

FIG. 14 is an overall cutaway top viewpoint of an example of a main air register portraying the various major components as related to their adjustability and functionalities. As illustrated in the example of FIG. 14, a Top perspective view of the main register 43 and components are shown, prior to boot installation. Shown is an internal view 44 of longitudinal recessed support frame with attached spring snap and button for securing longitudinal frame adjustments. A spring loaded button 45 is for securing longitudinal and securing longitudinal main frame adjustments. Force generating means 46 for louver movement are disposed in Removable cartridge housing louver compartment 41. Microcontroller receiver components are housed within the component housing cavity 47. Shown is an internal view 48 of the main register compression corner spring within the frame. On the Main register compression corner spring frame housing is disposed a travel guide opening 49. On the Longitudinal recessed support frame is attached a fixed button 50 for securing longitudinal frame pressure travel movement. In one example, one or more additional length-adjustable louvers are added for extended width configurations.

FIG. 15 demonstrates, in order, a tool-free installation example of the main register assembly and a fully adjustable grill assembly being placed within a typical ceiling mounted air boot. Main adjustable grill assembly 51 is disposable on Main adjustable register assembly 52. Main adjustable register assembly 52 is insertable into a Typical air register receiver boot 53. The compression spring frame of width and length adjustable Main adjustable register assembly 52 conforms to the size of the air register receiver boot 53. The width and length adjustable grill assembly 51 conforms to the compression spring frame of width and length adjustable Main adjustable register assembly 52.

In one example as illustrated in FIG. 15, tool free installation and removal of the adjustable air vent register frame and grill assembly is possible, such that the frame and grill can be easily installed and removed by a homeowner or general handyman for scheduled cleaning without the use of tools.

In one example, provided is a battery powered remote controlled plurality of adjustable vent louver blades mounted to rotate within the adjustable air vent register frame and adjustable grill assembly. Each component within the main frame is capable of extending in a manner that accommodates different width size air duct boot compartment openings while fully extending the louvers in a linear fashion within the frame to accommodate the standard air boot lengths.

In yet another example, an object of the present invention is to incorporate a battery powered digital thermometer housed within the above mentioned potentiometer transmitter plate capable of displaying room temperature changes as a result of remotely signaling minor adjustments to the linear adjustable vent louver blades housed within the fully adjustable frame. This remote potentiometer action allows for the slightest movement control angle of the louvers to change the desired air flow which further provides the user to more precisely control the room's temperature, which results will be clearly indicated by the attached digital thermometer mounted on the independent transmitter.

In several examples of the present invention, the present invention can produce the same results claimed by the much more expensive conventional Multi-Zone HVAC Systems. A further advantage of the present invention is the ability to control the air in a particular room of a house or structure by changing that specific individual room's register, whereas typical conventional Multi-Zone HVAC Systems affect several rooms in a zone.

In present day, a home office that needs extra air conditioning during the day, and none at night or occupants that may only use the upstairs bedrooms when guests visit can be conveniently regulated by an inexpensive fully adjustable battery powered electric remote-controlled air vent register frame and grill assembly. The results of which could only be previously achieved by use of a conventional Multi-Zone HVAC System. Conventional Multi-Zone HVAC Systems generally control several areas of a home or structure. The present invention can be used to control the environment in a single room if necessary without the cost of a Multi-Zone HVAC System.

Other examples of the invention. In one example, the transmitter and receiver use special orientation signal(s) to orient the register louvers when re-powered. In another example, the motor shaft is keyed to be installable only when the louver position is fully open; to make sure that default position is fully open. In another example, the motor case has a slit or key to prevent the battery pack from being inserted if the louvers are not in fully open position. In yet another example, the motor case has a slit or key that moves the louvers to the fully open position upon insertion of the battery back, in one example camed or by a cam shape. In one example, when the microcontroller on the motor-receiver detects low battery it moves the louvers to the fully open position and starts blinking the LED indicator. It then ignores further commands from transmitter. In one example, when microcontroller on the remote-transmitter detects low battery it sends a signal to fully open louvers and starts blinking the full-open LED, ignoring further button presses, then continues blinking until the battery is exhausted. In one example, a snap compression fit is used for the motor box to be received by the register housing.

In another example, a syncing and operating process is programmed into the microcontrollers, comprising one or more of the following steps:

• • 1. transmitter in rest condition will not be transmitting and the LEDS will go dark and will remain dark;
  • 2. rest condition starts shortly after there is a pause in pressing the command buttons;
  • 3. upon pressing the up or the down button the transmitter remote cycles through the LED's;
  • 4. upon the micro controller detecting a pause in the pressing of the up or down button, the current position (represented by the LED) is sent as a signal that represents the amount of open or closed (the selected position) for the receiver to use to set the position of the louvers;
  • 5. the motor-receiver receives the current position signal and moves the louvers to the selected position that was communicated by the transmitter.
