DETAILED DESCRIPTION

(29) It is to be understood by a person having ordinary skill in the art that the present discussion is a description of exemplary embodiments only and is not intended as limiting the broader aspects of the present invention, The following example is provided to further illustrate the invention and is not to be construed to unduly limit the scope of the invention.

(30) Referring now specifically to the drawings, FIGS. 1, 2, 3 and 4 show a truck 50 having a tailgate 52 connected to a trailer 40. Trailer 40 has a crank jack 42 attached near a tongue portion of the trailer. As shown in FIGS. 2 and 4, the tailgate 52 of the truck 50 is prone to impacting the crank jack 42 of the trailer 40.

(31) Referring to FIGS. 5, 6, 7, and 8, the cushioned protection device 10 of the present invention has been installed on the crank jack 42. As shown in FIG. 5, the cushioned protection device 10 may use a multipart design 30 that is made from different layers of foam. As shown in FIG. 7, the cushioned protection device 10 may also be constructed from a single piece of foam 20, As shown in FIGS. 6 and 8, when the cushioned protection device 10 is installed, it will protect the tailgate 52 of the truck 50 from the impact of the crank jack 42 of the trailer 40.

(32) Referring to FIGS. 9, 10, 11, 12, 13, 14, 15, and 16, the cushioned protection device 10 slips over the crank jack 42. This is so with both the multipart design 30 of FIGS. 9, 10, 13, and 14 and the single foam design 20 of FIGS. 11, 12, 15, and 16. As shown in FIGS. 9-16, internal cavity 60 slides over the crank jack 42 and fits securely around the crank jack 42. The internal cavity 60 is sized to fit snugly over and around the crank jack 42. The spring properties of the foam of the cushioned protection device 10 hold the cushioned protection device 10 around the crank jack 22,

(33) As shown in FIGS. 17, 18, 19, 20, 21, 22, 23, and 27, the internal cavity 60 may include side opening 62, bottom opening 64, and upper portion 66. The internal cavity 60 has a plurality of internal surfaces which contact the crank jack 42 and generally correspond to the shape of the crank jack 42, The bottom opening 64 may have a shape which corresponds to the shaft of the crank jack 42. This shape may have at least a partial circular cross-section. The bottom opening 64 is shaped to accept and to be installed over the crank jack 42. The side opening 62 works in conjunction with the bottom opening 64 in order to surround the crank jack 42. In some embodiments (not shown) the side opening may be optional as the entirety of the crank jack may fit within the cavity without need for the side opening 62. In some embodiments, the side opening 62 is designed to accommodate a handle portion of the crank jack 42 whereas the bottom opening is primarily designed to accommodate the shaft portion of the crank jack 42. Similarly, the upper portion is designed to house that portion of the crank jack 42 which is located above the shaft portion of the crank jack 42. The upper portion 66 may have a rectangular cross-section.

(34) The multi-part design 30 of the cushioned protection device 10 is shown in FIGS. 19, 20, 22, and 24 and may be contrasted with the solid design 20 of the cushioned protection device 10 shown in FIGS. 21, 23, and 25. The multi-part design 30 may include several different layers. Each of these layers may be made from different types of foam. Each of the foams may have different densities, As shown, in FIG. 19, the multi-part design 30 may include three different portions namely an upper protection portion 32 protecting the tailgate 52, a central protection portion 34 for providing rigidity and for providing a secondary cushioning, and a lower protection 36 portion for securing the cushioned protection device to the crank jack. Lower protection portion 36 may be a single piece of foam or may be made from two parts, 35, 37, as shown.

(35) The lower portion 36 may be made from a polyethylene foam having a density of about 1.65 pounds per cubic foot. Where the lower portion 36 is made from two different pieces,the different pieces 35, 37 are preferably made from the same type of foam. The pieces 35, 37 may be adhered to one another using heat melt, weld, or glue. The foam may be made from a recycled foam. The lower portion houses the cavity 60.

(36) The central portion 34 may be made from a polyethylene foam having a density of about 6 pounds per cubic foot. It may be adhered to the lower portion 36 via heat melt, weld, or glue. The central portion 34 may be made from a solid block of foam, having no portion of the cavity 60 therein, and may be less than 10% of the thickness of the upper portion 32. The upper portion 32 may be made from a polyethylene foam having a density of about 1.7 pounds per cubic foot. It may be adhered to the central portion 34 via heat melt, weld, or glue. Preferably, the upper portion 32 is a solid block wherein no portion of the cavity 60 enters the upper portion 32.

(37) Alternatively, the, cushioned protection device 10 may be made from a single block of foam 20. The single block of foam 20 is made from a polyethylene foam having a density of greater than about 1.7 pounds per cubic foot but less than about 6 pounds per cubic foot.
