DESCRIPTION OF THE INVENTION
Turning now to the drawings and more particularly to figure 1 we have a perspective view of a sport utility vehicle 22 having a Vehicle Wind Deflector 20 strapped 24 on the rear end portion thereof. In the embodiment of the invention shown in figure 1 the straps 24 are positioned between the top interior corners of the Vehicle Wind Deflector 20 and the rain gutter 26 which extends horizontally over the side windows of the vehicle 22, as well as on the bottom portion of the side members 28 of the wind deflector 20.
Figure 2 is an enlarged perspective view of the Vehicle Wind Deflector 20 shown in figure 1. The Wind Deflector 20 comprises a top member 30 having a front side portion seated on and extending across the rear portion of the vehicle 22, said top member 30 curving upwardly from its front side portion to its rear side portion; two side members 28 each having a top side portion releasably fastened to opposite end side portions of the top member 30, a front side portion extending downwardly along the side portion of the vehicle 22, said side members 28 curving outwardly from their front side portion to a rear side portion thereof; and, releasable fastening means 40, 24 for fastening the top and side members to the vehicle 22. The front side portion of the top member 30 is generally the width of the 216649~
-vehicle 22. The front side portion of the side members 28 is generally the height of the vehicle 22 as measured from the bottom of the frame 32 to the top of the roof 34. The rear side portion of the top member 30 is generally 18" higher than the roof 34 of the vehicle 22. The top side portion of the top member 30 curves upwardly from the front side portion thereof to the rear side portion thereof. Measured along the length of the vehicle 22 the top member 30 and two side members 28 have a depth of generally 2 feet. Like the top member 30 the two side members 28 each also curve outwardly generally 18". That is the rear side portions of the side members 28 are together generally 36"
wider than the front side portions of the side members 20 as measured laterally across the vehicle 22. It should be understood that the outward curvature and depth of the members 30, 28 may be varied to best deflect wind for a specific size of vehicle 22 pulling a particular size of trailer (not shown).
Figure 2 also shows an alternative and preferred means for anchoring the top member 30 to the vehicle 22. A hook bolt 40 has a bottom portion which hooks beneath the rain gutter 26, a central portion which extends upwardly through the opposite ends of the front lip 38 on the top member 30, and a top end portion having a wing nut 42 thereon. As shown in figure 1 straps 24 are used for anchoring the bottom portion of the side members 28 to the vehicle 22. A protective rubber grip strip 36 extends around the interior of the front lip 38 on the members 28, 30.
Figure 3 is a rear view of the vehicle taken along line 3-3 in figure 1. Braces 44 extend perpendicularly outward, and rearwardly from the front lip 38 of the members 28, 30. In the preferred embodiment of the invention there are two braces 44 spaced on each member 28 or 30. Each brace 44 also extends rearwardly and inwardly from the back central and interior portion of each respective member 28 or 30. A steel bar 46 welded to the lower portion of the frame 32 of the vehicle 22 extends laterally outwards so that the bottom portion of the side members 28 may rest thereon and be strapped 24 thereto. In the preferred embodiment there are two bars 46 each having an interior side portion rotatably mounted on the frame 32 so that they may be rotated inwardly when not in use. Buckles 48 positioned between the top member 30 and side members 28 releasably fasten the two together.
Figure 4 is an enlarged cross sectional view taken along line 4-4 on figure 2. One of the top member 30 and a side member 28 has a vertically extending projection 50 which is matably received by the other of the two. A buckle 42 releasably holds the top 30 and side members 28 together.
The members 28, 30 are molded from a durable semi rigid plastic. They are lightweight, and when disassembled they are compact and convenient to store or ship. Before they are used a bar 46, must be fastened to the frame 32 beneath the vehicle 22.
In the preferred embodiment, two bars 46 are used, each has an interior end portion which is bolted 52 to the frame 32 so that said bars 46 may be rotated inwardly when not in use. After the bars 46 are mounted on the vehicle 22 the next step which must be taken to use the wind deflector 20 is to buckle 42 the top 30 and side members 28 thereof together. The wind deflector 20 is then seated over and around the rear portion of the vehicle 22.
Straps 24 are tied to the bars 46 and the hook bolts 40 are tightened catching beneath the rain gutter 26 on the vehicle 22.
After use the Vehicle Wind Deflector 20 may be removed from the vehicle 22 without marring or otherwise marking it. The wind deflector 20 is easily disassembled for storage.
While the invention has been described with preferred specific embodiments thereof, it will be understood that this description is intended to illustrate and not to limit the scope of the invention, which is defined by the following claims.
