ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an air duct register system and more particularly pertains to controlling and directing the flow of heated and cooled air into a chamber.
2. Description of the Prior Art
The use of air registers of known designs and configurations is known in the prior art. More specifically, air registers of known designs and configurations previously devised and utilized for the purpose of controlling air flows through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 3,938,430 to Koppang discloses air vents. U.S. Pat. No. Des. 413,665 to Hudson discloses a heating, ventilating, and air conditioning register. Lastly, U.S. Pat. No. 5,312,298 to Myers discloses a floor vent.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe an air duct register system that allows controlling and directing the flow of heated and cooled air into a chamber.
In this respect, the an air duct register system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of controlling and directing the flow of heated and cooled air into a chamber.
Therefore, it can be appreciated that there exists a continuing need for a new and improved an air duct register system which can be used for controlling and directing the flow of heated and cooled air into a chamber. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of air registers of known designs and configurations now present in the prior art, the present invention provides an improved An air duct register system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved An air duct register system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises an air duct register system for controlling and directing the flow of heated and cooled air into a chamber, which comprises several components in combination. The register has a face plate which covers a duct or opening. It has a rectilinear configuration with long upper edges and lower edges and short side edges and is sized to cover the opening of an air duct into a chamber. The face plate is fabricated of rigid material, preferably a metal such as aluminum. It has an internal face and an external face. There are two fixation apertures adjacent to the side edges adapted to receive attachment screws. The face plate has a rectangular, central opening. The opening is such that the height and width is less than the lengths of the edges to form a solid periphery of between about 1.0 and 2.0 inches around the edges of the faceplate. The central opening has a series of air directing grates angled at between about 5 and 20 degrees toward the outside of the opening. This plurality of rectangular shaped slots through the face plate directs air outward at an angle, as opposed to directing the air straight out. On the internal side of the face plate is a rectilinear housing which comprises two parallel long side walls and two parallel short end walls. The walls are oriented perpendicular to the internal face and have external edges coupled to the interior face of the face plate adjacent to the opening. The end plates each contain two large bores and one small bore, the large bores are located near the external edge and equidistant from the midline of the width of the end plate. The smaller bore is located interiorly on the end plate, with its center in line with the center of one of the large bores. Within the housing is located a pair of similarly configured flappers. These have a generally rectangular configuration with two parallel long edges and two parallel short edges. The short edges are perpendicular to and connect to the ends of the long edges, forming a rectangular flapper. The flappers are slightly wider than 50 percent of the height of the opening and slightly shorter than the width of the opening. There is an arcuate ridge along the central portion of the flapper on the long axis midline. This ridge runs the entire length of the flapper and ends on each end of the flapper with a formed cylindrical extension. This extension is then rotatably received within the large bores of the housing, which allows the flapper to pivot about this axis. A control assembly which has an actuator subassembly, activates and controls the flappers. The actuator subassembly comprises a main plate in a generally semi-circular configuration. It has an exterior edge configured with ridges and indentations bent to provide a gripping surface. The main plate extends through a slot for control by a user. The plate also has an outwardly extending pin rotatably received in the small bore, allowing the main plate to pivot. The plate also has an outrigger arm with a fork which attaches to an edge of one of the flappers. The plate and arm are configured to allow the rotation about a course of travel of between 0 and 90 degrees for opening and closing the flappers. The control assembly also has a follower subassembly which comprises a link which has a proximal end and distal end. It is located adjacent to and parallel with the end plate remote from the actuator sub assembly. The proximal end is generally rounded with a hole. A flapper tab, which has a hole in it, is aligned with the hole at the proximal end and secured with a rivet through the two holes, forming a connection. The distal end of the follower subassembly has a hook-like extension on the link which extends through the hole on the other flapper tab. This allows for the rotation of the flapper coupled to the control assembly to rotate the other flapper as well.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved an air duct register system which has all of the advantages of the prior art air registers of known designs and configurations and none of the disadvantages.
It is another object of the present invention to provide a new and improved an air duct register system which may be easily and efficiently manufactured and m
