Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The present invention relates to a ventilation register system. More specifically, the invention is a register system for HVAC applications having interchangeable decorative frame inserts. BACKGROUND OF THE INVENTION [0002] In the heating, ventilation and air-conditioning (HVAC) industry, registers are commonly covered by decorative faceplates. Depending upon the application, the faceplates are commonly made of brass, aluminum, wood, or steel. In order to change the appearance of the faceplate, a complete replacement must be purchased, which is expensive. [0003] Changing the appearance of the faceplate can be aesthetically pleasing, which allows a homeowner to change the look in a room and match the faceplate to the decor. Therefore, what is needed is a decorative faceplate that is easy and inexpensive to replace. SUMMARY [0004] The present invention relates to ventilation register system, the invention comprises a frame and a grate. The frame defines an opening and the grate is sized and shaped for complementary engagement within the opening. [0005] In one aspect of the invention, the invention further comprises a plurality of engagement members. The engagement members enable complimentary engagement of the circumferential edge of the grate with the interior sidewall of the opening of the frame. [0006] In one aspect of the invention, each engagement member comprises a body member, a piston member, and a bias element. In this aspect, the body member defines an interior cavity and has an opening in one end of the body member. In this aspect, the piston member is disposed within the interior cavity of the body member and forms the distal portion of the engagement member. The bias element is disposed within the interior cavity and is supported by the second, opposed end of the body member. In use, the bias element engages the piston member to move the piston member between a first position and a second position. BRIEF DESCRIPTION OF THE DRAWINGS [0007] These and other features of the preferred embodiments of the present invention will become more apparent in the detailed description in which reference is made to the appended drawings wherein: [0008] FIG. 1 is a perspective view of the ventilation register system of the present invention showing an assembled view of the frame and grate assembly. [0009] FIG. 2 is a partially exploded perspective view of the ventilation register system of FIG. 1, showing the frame, the grate, and a plurality of engagement members. [0010] FIG. 3 is front cut-away view of the ventilation register system of FIG. 1, cut along the line 3-3. [0011] FIG. 4 is a partial cut-away perspective view of an engagement member of one aspect of the ventilation register system of the present invention. DETAILED DESCRIPTION OF THE INVENTION [0012] The present invention is more particularly described in the following exemplary embodiments that are intended as illustrative only since numerous modifications and variations therein will be apparent to those skilled in the art. As used herein, "a," "an," or "the" can mean one or more, depending upon the context in which it is used. The preferred embodiments are now described with reference to the figures, in which like reference characters indicate like parts throughout the several views. [0013] Ranges may be expressed herein as from "about" one particular value, and/or to "about" another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment. [0014] In one aspect of the present invention for a ventilation register system 10, the invention comprises a frame 20 and a grate 40. The frame 20 defines an opening 22 and can comprise almost any substantially rigid material. The frame can comprise, for example, aluminum, steel, wood, plastic, and the like. The frame may comprise a variety of colors and shapes. In one aspect, the frame is rectangular. [0015] The grate 40 is configured for complementary engagement within the opening 22 of the frame and may be vented to enable air to pass therethrough. The grate 40 may also comprise any substantially rigid material, such as, but not limited to, aluminum, brass, steel, iron, copper and the like. [0016] In one aspect, where the interior sidewall of the frame is metallic, at least a portion of the circumferential edge 42 of the frame 20 comprises a magnetic material with which to releasably engage the interior sidewall 24. Similarly, where the circumferential edge of the frame comprises a metallic material, at least a portion of the interior sidewall may comprise a magnetic material with which to releasably engage the circumferential edge. [0017] In another aspect, the grate 40 is substantially weighted such that gravity alone is enough to releasably engage at least a portion of the interior sidewall 24 with the circumferential edge 42 of the grate. In yet another aspect, the circumferential edge of the grate comprises at least one tab (not shown). In this aspect, the interior sidewall comprises a complimentary receptacle (not shown) with which to engage the at least one tab of the grate. [0018] In still another aspect, the present invention also comprises and a plurality of engagement members 60. The engagement members 60 enable complimentary and selectively releasable engagement of the circumferential edge 42 of the grate 40 with the interior sidewall 24 of the opening 22 of the frame. In one aspect, the engagement members 60 are positioned within at least a portion of the interior sidewall. A distal portion 62 of each of the engagement members is moveable from a first position in which the distal portion of the engagement member protrudes outwardly therefrom the interior sidewall 24, to a second position in which the distal portion of the engagement member is substantially coplanar with the interior sidewall. When the distal portion 62 of the engagement member 60 is in the first position, it is engageable with a portion of one of a plurality of complimentarily positioned cavities 44 defined within the circumferential edge 42 of the grate 40. [0019] In another aspect, the engagement members 60 are disposed within at least a portion the circumferential edge 42 of the grate 40 instead of the interior sidewall 24 of the frame 20. In this aspect, the cavities are complimentarily positioned within the interior sidewall of the frame. As such, the distal portion of each of the engagement members is moveable from a first position in which the distal portion of the engagement member protrudes outwardly therefrom the circumferential edge of the grate, to a second position in which the distal portion is substantially coplanar with the circumferential edge.
