Cushioning bathtub liner
A one-piece foam plastic bathtub cushion is presented, intended for therapeutic and ordinary bathing uses. The cushion is self-drying and non-skid, in the shape of a human torso, and easy to roll up and store. The cushion can be made in two-layers, the top layer of cushioning material, the bottom layer made of tougher, non-skid plastic.
[0001] This invention relates to therapeutic bathtub devices and apparatuses, in particular to bathtub cushions and non-slip pads.
[0002] Existing bathtub liners and pads have as their primary purpose to provide cushioning or support for convalescent or elderly bathtub users, or to provide specialized seating position inside a bathtub. The prior art includes complicated, articulated pads or very complicated seating devices. There is no prior art involving a single-piece shaped pad with a non-skid surface intended to sit on the bottom of a bathtub.
[0003] The prior art discloses therapeutic pads as in U.S. Pat. No. 4,037,591, full-tub cushions as in U.S. Pat. Nos. 2,264,672 and 5,715,546, recliners such as U.S. Pat. Nos. 2,541,029 and 5,052,965, and 6,038,969, and ground pads such as U.S. Pat. No. 2,751,609.
[0004] None of these devices have the single or double-layer construction that the present invention possesses, nor do any of them have a combination of soft surface foam and non-skid surface.
[0005] This invention differs from the above-listed devices by virtue of its low-cost manufacture, its ease of use, storage, and self-drying capability.
BRIEF SUMMARY OF THE INVENTION[0006] It is an object of this invention to provide a low-cost bathtub cushion.
[0007] It is an object of this invention to provide such a cushion in a two-layer foam construction.
[0008] It is an object of this invention to provide such a cushion where the shape of the cushion conforms to the human body, minimizing weight.
[0009] It is a further object of this invention to provide such a cushion in a form that can be easily dried by standing on its end.
[0010] It is a further object of this invention to provide such a cushion in a form that can be easily rolled up for storage.
[0011] Further objects of this invention can be discerned by perusing the detailed description, drawings, specifications and claims of this application.
BRIEF DESCRIPTION OF THE DRAWINGS[0012] The construction and operation of the invention can be readily appreciated from inspection of the drawings that accompany this application, combined with the detailed specification to follow.
[0013] FIG. 1 is a perspective drawing of the preferred embodiment of the invention placed in a bathtub.
[0014] FIG. 2 is a top view diagram of the invention.
[0015] FIG. 3 is a side view of the single-layer embodiment of the invention.
[0016] FIG. 4 is side view of the double-layer embodiment of the invention.
DETAILED DESCRIPTION OF THE INVENTION[0017] The invention is best described by referring to the preferred embodiment illustrated in the drawings in FIG. 2 and FIG. 4.
[0018] Referring to FIG. 2, a cushioning bathtub liner101 is a foam plastic pad that is shaped roughly like the human head and torso in silhouette. The pad is composed of two layers, a top layer102 and a bottom layer103. An alternative embodiment is illustrated in FIG. 3, where the pad is the same human silhouette shape as illustrated in FIG. 2, but there is a single layer of plastic foam104 The two layers of foam are glued together when manufactured, and the top layer102 is made of absorbent, soft foam plastic, such as a double-cell foam. The bottom layer103 is made of a foam that is non-skid and dries quickly, such as reticulated polyester.
[0019] The single-layer version is less expensive to manufacture. The preferred, double-layer embodiment is more comfortable and has better non-skid properties.
[0020] While the foregoing describes a preferred and alternate embodiment, variation on this design and equivalent designs may be resorted to in the scope and spirit of the claimed invention.
Claims
1. a bathtub cushion, the cushion comprised of flexible plastic foam, the plastic foam in a flat piece,
- the thickness of the piece of plastic foam substantially smaller than the width of the piece such that the piece can be rolled up,
- the piece of plastic foam shaped in the silhouette of a typical human head and torso,
- the piece of plastic foam having cushioning properties when sat or laid down on,
- the piece of plastic foam also having non-skid properties when placed in a wet or dry bathtub.
2. A cushion as in claim 1, wherein the piece of plastic foam is in two layers, the layers in roughly equal thickness, the layers consisting of a top layer and a bottom layer, the top layer comprised of flexible, soft, cushioning foam plastic, the bottom layer comprised of flexible, non-skid plastic.
