8. A cot in the form of an integral one-piece body molded of hard thermoplastic material and configured so as to provide sufficient strength to support several times the weight of an occupant and yet permit a substantially uniform wall thickness sufficiently thin that the cot is light in weight and flexible for comfort;
- said body comprising;
a. a top wall means of generally rectangular shape having two straight sides and two straight ends, said two straight sides being straight over substantially the entire distance between said two straight ends, said two straight ends being straight over substantially the entire distance between said two straight sides, with said top wall means forming a generally rectangular shaped ridge having upper wall portions which have a continuously curving transverse section except the upper wall portion at one end which has a generally flat portion with dimensions sufficient to form a head rest, and with the upper extremity of said ridge of said top wall means being tangent to a first plane; b. a straight supporting sidewall merging with and depending from each side and from each end of said top wall means tapering slightly outward in a downward direction, with each said support sidewall merging with adjacent support sidewalls in a continuously curving manner, with said support sidewalls having bottom edges spaced from said top wall means and which flange outward for engaging the floor of a house or building in a plane generally parallel to said first plane for supporting said top wall means above and spaced from the floor, and with the juncture of said bottom edges and the rest of said support sidewalls having a continuous curvature; c. a web portion providing an upward facing surface for supporting a person and disposed generally at a level between said ridge upper wall portions and the bottom edges of said supporting sidewalls; d. said ridge of said top wall means further comprising inner sidewall portions merging at their upper edges with and depending from said upper wall portions and merging at their lower edges with said web at the periphery thereof in a continuously curving manner. - View Dependent Claims (9, 10, 11)
