Bathtub liner

Claim 1

In combination with a bathtub having a drain, an upper peripheral edge, a bottom surface and inner side surfaces, a portable resilient bathtub liner including (a) a first resilient pad covering and contacting said bottom surface of said bathtub, said pad including an inner core of resilient material enclosed by a layer of water resistent material which detachably adheres to said bottom surface of said bathtub, said pad tapering from one of said ends to the other of said ends such that water in the bathtub flows under the force of gravity from one of said ends down said pad toward said bathtub drain when water is being emptied from said bathtub through said drain; (b) an upright elongate second resilient pad of generally uniform symmetrical triangular cross section along the length thereof and positioned inside said upper peripheral edge of said bathtub and having (i) an elongate bottom portion positioned adjacent said first pad and parallel to said bottom surface of said bathtub, (ii) an elongate top portion generally parallel to said bottom portion, (iii) a height equal to the shortest distance between said bottom portion and said top portion, (iv) an outer generally continuous smooth planar surface spanning the distance between said top and bottom portions, facing one of said inner side surfaces of said bathtub, and formed of a material which detachably adheres to said one of said side surfaces, substantially the entire area of said outer surface contacting said one of said side surfaces of said bathtub, (v) an inner generally smooth planar surface opposed to and spaced apart from said outer surface, spanning the distance between said top and bottom portions, and sloping upwardly from said bottom portion toward said one of said side surfaces of said bathtub and said outer planar surface of said second pad, the center of gravity of said second pad being in said second pad at a distance from said bottom portion equal to less than one-half of said height of said second pad, the force of gravity's acting on said second pad stabilizing said second pad against said one of said side surfaces of said bathtub; and, (c) elastic strap means having (i) a first end attached to said first pad, and (ii) a second end attached to said bottom portion of said second pad, said elastic strap means pulling said bottom portion of said second pad downwardly toward said bottom surface of said bathtub.
