DESCRIPTION OF THE INVENTION

(16) The present invention is directed to a scissor jack cover (herein described as the “invention”) 100. The invention 100 may be a protective cover for an individual scissor jack 902. The individual scissor jack 902 may be coupled to the underside of a vehicle. The individual scissor jack 902 may be placed in a collapsed configuration and may be covered by the invention 100 while the vehicle is in motion. The individual scissor jack 902 may be protected from water, road salt, dirt, and other contaminants while residing inside of a cavity 242 within the invention 100. Contaminants may promote oxidation of the individual scissor jack 902 and may mix with lubricants used on the individual scissor jack 902, both of which may make the individual scissor jack 902 difficult to operate. The vehicle may employ a plurality of scissor jacks to level and stabilize the vehicle when the vehicle is stationary. As a non-limiting example, the vehicle may be a toy hauler trailer, a recreational vehicle, a travel trailer, a motor home, or other conveyance. Multiple instances of the invention 100 may be deployed to protect each of the plurality of scissor jacks dispersed beneath the vehicle.

(17) The individual scissor jack 902 may be placed in an expanded configuration by cranking a threaded rod 904 in a first rotational direction using a crank handle. In the expanded configuration, a plurality of lifting arms 910 may pivot towards a vertical orientation to increase the separation between a base 906 of the individual scissor jack 902 and one (1) or more top plates 908 that couple the individual scissor jack 902 to the vehicle, thus pressing the base 906 against the ground. The individual scissor jack 902 in the expanded configuration may lift the vehicle to level the vehicle, may stabilize the vehicle during stationary use of the vehicle, or both.

(18) The individual scissor jack 902 may be placed in the collapsed configuration by cranking the threaded rod 904 in a second rotational direction which is opposite the first rotational direction. In the collapsed configuration, the plurality of lifting arms 910 may pivot towards a horizontal orientation to decrease the separation between the base 906 and the one (1) or more top plates 908, thus raising the base 906 from the ground.

The rear top panel 226 may cover the top side of the plurality of lifting arms 910 at the rear of the individual scissor jack 902.

(25) The first door panel 230 and the second door panel 234 may comprise overlapping flaps at the top front of the invention 100. The first door panel 230 and the second door panel 234 may be coupled to the left side panel 200 and the right side panel 202, or vice versa. The first door panel 230 and the second door panel 234 may overlap to cover the plurality of lifting arms 910 at the front of the individual scissor jack 902 and to hold the invention 100 in place on the individual scissor jack 902. When overlapping, a first fastener 232 on the first door panel 230 may engage a second fastener 236 on the second door panel 234 to hold the door flaps 250 closed. As a non-limiting example, the first fastener 232 and the second fastener 236 may be halves of a hook-and-loop-type fastener. The first door panel 230 and the second door panel 234 may be decoupled from each other and opened to expose the cavity 242 within the invention 100 for inserting or removing the individual scissor jack 902.

(26) The left side panel 200 and the right side panel 202 may cover the left and right side of the individual scissor jack 902, respectively. The left side panel 200 may be coupled to the left side of the bottom panel 220, the rear underpanel 222, the front underpanel 224, and the rear top panel 226. The right side panel 202 may be coupled to the right side of the bottom panel 220, the rear underpanel 222, the front underpanel 224, and the rear top panel 226.

(27) Where edges of two (2) of the panels meet, the panels may be coupled. As non-limiting examples, the panels may be coupled using stitched seams such as plain seams or lapped seams, adhesives, rivets, other fasteners, or combinations thereof. The invention 100 may comprise a plurality of tabs 228 to aid in the coupling of the panels. An individual tab may be an extension of an individual panel. As non-limiting examples, the individual tabs may be coupled to an adjacent panel or to another individual tab. The plurality of tabs 228 may also be operable to reinforce the material comprising the panels. As a non-limiting example, the individual tab may be folded back one hundred eighty degrees (180°) onto the individual panel that the individual tab is an extension of and may be coupled to the individual panel, thus doubling the thickness of the material at the edge of the individual panel. As a non-limiting example, the jack aperture 240 may be reinforced by the plurality of tabs 228 on the panels surrounding the jack aperture 240.

(28) The base 906 may be larger than the jack aperture 240, therefore the sides of the invention 100 may slope inwards towards the top. In addition, the plurality of lifting arms 910 may be narrower than either the base 906 or the jack aperture 240, therefore the front wedge 280 and the rear wedge 282 may be narrower from side to side at the distal ends of the front wedge 280 and the rear wedge 282 than at the proximal ends of the front wedge 280 and the rear wedge 282. Because of this, an individual side panel selected from the left side panel 200 and the right side panel 202 may define a center trapezoid portion 212, a front triangle portion 214, and a rear triangle portion 216. The center trapezoid portion 212 may extend from the base 906 to the jack aperture 240 and may slope inwards towards the top of the invention 100. The front triangle portion 214 may cover one (1) side of the front lifting arms and may be non-coplanar with the center trapezoid portion 212. The rear triangle portion 216 may cover one (1) side of the rear lifting arms and may be non-coplanar with the center trapezoid portion 212 and non-coplanar with the front triangle portion 214.

(29) FIG. 5 is a left side view of a scissor jack cover 100, according to an embodiment of the present invention. FIG. 6 is a right side view of a scissor jack cover 100, according to an embodiment of the present invention. In some embodiments, the invention 100 may be formed from a single sheet of material 260 that may be cut or stamped according to a pattern. The pattern may define the left side panel 200, the right side panel 202, the bottom panel 220, the rear underpanel 222, the front underpanel 224, the first door panel 230, the second door panel 234, the rear top panel 226. The pattern may be optimized to reduce waste. As a non-limiting example, the pattern may be substantially symmetrical in both lateral and longitudinal directions.

(30) As non-limiting examples, the panels of the invention 100 may be made from waterproof canvas, vinyl, coated polyester, polyethylene, ripstop nylon, or combinations thereof.

(31) There may be many ways that the invention 100 can be cut from the single sheet of material 260 and FIG. 10 illustrates one such embodiment. Note that in FIG. 10, the left side panel 200 and the right side panel 202 are both separated into the center trapezoid portions 212, the front triangle portions 214, and the rear triangle portions 216. The center trapezoid portion 212, the front triangle portion 214, and the rear triangle portion 216 on the left side may be coupled to form the left side panel 200. The center trapezoid portion 212, the front triangle portion 214, and the rear triangle portion 216 on the right side may be coupled to form the right side panel 202. Also note in FIG. 10 that the rear top panel 226 may be split longitudinally into a first rear top panel half 252 and a second rear top panel half 254 which may be coupled to each other to form the rear top panel 226.
