Patent number: 6916240Abstract: A register system for air flow regulation, directing, damping and filtering attachable to individual building air supply outlets said as typically found in building rooms wherein air flow from a central air supply enters a room of the building through a duct in a partition of the room. The system is particularly useful for persons said as asthmatics who require additional room air filtering and special needs relating to air damping and airflow. Many of these persons find direct airflow on their person to be irritating. The present invention allows for said persons to directly (or through the use of an extendable pole) re-direct one or more individual air deflectors to aim the air in almost any direction. Furthermore, said persons may directly (or through the use of an extendable pole) adjust individual dampers in each air deflector for adjusting the air volume.Type: GrantFiled: September 6, 2002Date of Patent: July 12, 2005Inventor: Steven J. Morton

Patent number: 6129627Abstract: An air outlet assembly is used to direct airflow of a climate control system of a motor vehicle. The air outlet assembly is used by the passengers sitting on a back seat in a passenger compartment. The air outlet assembly includes first and second doors which are used to open and close an outlet thereof. The doors also direct the air flowing therethrough. An actuator moves the doors between their respective open and closed positions. The actuator moves the second door from its open position, 90.degree. with respect to the air outlet opening, toward its closed position as it moves the first door from an intermediate position, 90.degree. with respect to the air outlet opening, toward its open position. This allows the doors to act in unison, after the first door passes the intermediate position, by moving in parallel form, to affect the direction of airflow. The actuator includes a single gear and rack for the first door and a pair of gears and a single rack for the second door.Type: GrantFiled: October 21, 1998Date of Patent: October 10, 2000Assignee: Collins & Aikman Plastics, Inc.Inventors: Ireneusz Jankowski, Derrick Wayban Chow, Robert Ronald Mitchell

Patent number: 6016976Abstract: A venting nozzle has a housing having an air inlet through which an air flow enters the housing. The housing has an outlet through which the air flow exits. The outlet has deflection elements for deflecting the air flow. Parallel flaps are pivotably connected in the housing for shutting off the air flow. Meshing gear segments are positioned in the housing and connect the flaps. The meshing gear segments are arranged outside the air flow. A rotary control is coordinated with one of the flaps for controlling positioning of the flaps.Type: GrantFiled: June 6, 1997Date of Patent: January 25, 2000Assignee: Aurora Konrad G. Schulz GmbH & Co.Inventors: Alfred Kern, Wolfgang Knuhl

Patent number: 5674124Abstract: This is an air register having a grille member pivotally attached to the register housing. A spring is disposed between the grille member and the register housing which biases the grille member in an upward, diagonal extended position from the central passageway formed inside the register housing. During use, the grille member is automatically disposed in an upward, diagonal extended position which deflects the exiting air at an angle into the room. When a downward force is applied to the top surface of the grille member, say by a person's foot, the grille member is able to pivot downward around one edge into a retracted position inside the central passageway. The air register also includes a pair of overlapping plates controlled by a control knob which control the amount of air exiting from the air register.Type: GrantFiled: February 8, 1995Date of Patent: October 7, 1997Inventor: Reed A. Davis

Patent number: 5447471Abstract: An air flow controller has an adjustable air flow passageway and comprises a surface-mounted distribution frame housing one or more elongate passages. Each passage has an inlet, a flow channel and an outlet. The inlet has two opposed guide flaps to control the flow of air passing into the flow channel. Two opposed wall members define the width of the channel, the wall members being adapted to be position-adjusted on control movement of the guide flaps with the outer ends of the wall members defining the outlet.Type: GrantFiled: June 20, 1994Date of Patent: September 5, 1995Assignee: Airrite Building Services LimitedInventor: Robert J. McDermott

Patent number: 5411438Abstract: At an outlet of a heating, ventilating or air conditioning system air passes from the ducting through a plenum chamber, a damper provided with a set of blades which are movable between open and closed positions and a diffuser which directs the air in a desired direction. The plenum chamber is provided with internal vanes which act to guide a flow of air through the chamber between its inlet and outlet. The damper defines a plurality of predetermined blade positions between the open and closed positions and a resilient finger and teeth for retaining the blades in a selected one of said predetermined positions. The damper has a frame comprising a plurality of discrete frame elements interconnected at each corner joint of the frame by a friction fit pin passing through interdigitated projections on the frame elements.Type: GrantFiled: March 22, 1993Date of Patent: May 2, 1995Assignee: Hunter Technical Developments LimitedInventors: David White, Colin Sawyer, Pater Bartingale

Patent number: 5180333Abstract: A ventilation device, which comprises a sensor unit, a fan and control units to control on/off operation and the strength, temperature, humidity and directions of the wind or discharged air. The device can be applied to air conditioners, and ventilators. The sensor unit, monitoring the location and existence of human bodies within the ventilating area, enables the fan and the control units to be on or off while sensing the first person who comes into the area or the last person who leaves the area; and to adjust the strength and directions of the wind based on the location of the human bodies. The sensor unit, furthermore, can follow a specific human body and actuate the control units to provide needed wind based on his/her requirement. When the fan stops operating, all the openings of the ventilation device will shut so that the dust cannot get into the ventilation device.Type: GrantFiled: October 28, 1991Date of Patent: January 19, 1993Assignee: Norm Pacific Automation Corp.Inventor: Jia-Ming Shyu
