STRUCTURE VENTILATION SYSTEM AND METHOD
A ventilation system having a cylindrical reducer, a pair of adjustable structural supports and a ceiling electrical box concentrically mounted to the structural supports. The electrical box is configured to support the weight of a ceiling fan assembly. The pair of adjustable structural supports include a first member and a second member that pass through the reducer. The members are hollow so that a first slidable strut extends from within a first end of the first member to a desired length and the second slidable strut extends from within an opposing second end of the first member to a desired length. Similarly, second member is hollow so that a third slidable strut extends from within a first end of second member to a desired length and fourth slidable strut extends from within an opposing second end of second member to a desired length.
1. Field of the Invention
The present invention relates generally to ventilation systems for structures, and more specifically to a novel vent apparatus for installation of a ceiling fan and/or light assembly that increases air circulation within a room.
2. Description of the Prior Art
It is common in the construction industry to install a number of vents in the ceiling for the distribution of air within a structure. A vent is placed in each room and a properly sized air duct supplies air of the desired temperature. The ventilation system functions to heat and cool a space as well as controlling air quality such as humidity. Accordingly, it is important function that the ventilation system be as efficient as possible. However, typically the location of air vents is not in the center of a room but rather in a corner or along the edge of the room. The ceiling space in the center of the room is typically reserved for a fan and/or light assembly. Therefore, the conditioned air is not distributed efficiently throughout the room but rather “hot” and “cold” spots are created.
There have been attempts to improve ventilation systems using a ceiling fan and air duct. By way of example, note U.S. Pat. No. 6,030,287 to Core that discloses a system for distributing air through the ceiling whereby the fan motor is installed within the air duct. A shortcoming of this prior art is that the motor is susceptible to condensation from cool air and electrical damage because it is located within the air duct. Another shortcoming is that a standard electrical ceiling box cannot be used with Core to mount a ceiling fan kit but instead an elaborate support structure is required.
Another example is U.S. Pat. No. 6,458,028 to Snyder that discloses a diffuser and ceiling fan as part of a ventilation system. Similar to the shortcomings of Core, the electrical ceiling box is mounted outside the ventilation duct so that a standard electrical ceiling box cannot be used to mount the ceiling fan assembly. Accordingly, what is needed in the art is a ventilation system that improves air circulation within a room using a standard electrical ceiling box well known in the industry for mounting ceiling fan kits and/or light assemblies.
Another need exists in the art for an improved ventilation system that can be easily retrofitted to an existing heating and air conditioning system.
Another need exists in the art for an improved ventilation system that can support a significant structural load from a fan and/or light assembly.
Another need exists in the art for an improved ventilation system that is aesthetically pleasing.
Another need exists in the art for an improved ventilation system that can be installed directly above any ceiling fixture in the room.
It is, therefore, to the effective resolution of the aforementioned problems and shortcomings of the prior art that the present invention is directed.
However, in view of the prior art at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled.
SUMMARY OF THE INVENTIONThis invention is a ventilation system comprising a cylindrical reducer, a pair of adjustable structural supports and an electrical box mounted to the structural supports. The pair of adjustable structural supports are comprised of a first member and a second member that pass through the reducer. The members are hollow so that a first slidable strut extends from within a first end of the first member to a desired length and the second slidable strut extends from within an opposing second end of the first member to a desired length. Similarly, second member is hollow so that a third slidable strut extends from within a first end of second member to a desired length and fourth sidable strut extends from within an opposing second end of second member to a desired length. The desired length of the structural supports is dependent on the distance between the ceiling trusses or other structural framing that will support the reducer and a fan and/or light assembly.
It is therefore a primary object of the invention to provide an improved ventilation that improves air circulation within a room using a standard electrical ceiling box well known in the industry for mounting ceiling fan kits.
Another object of the present invention to provide an improved ventilation system that can be easily retrofitted to an existing heating and air conditioning system.
Another object of the present invention to provide an improved ventilation system that can support a significant structural load from a fan and/or light assembly.
Another object of the present invention to provide an improved ventilation system that is aesthetically pleasing.
Another object of the present invention to provide an improved ventilation system that can be installed directly above any ceiling fixture in the room.
These and other important objects, advantages, and features of the invention will become clear as this description proceeds.
