' J. E. SMITH Dec. l, 1970 COT Filed April 25. 1968 United States' Patent O 3,543,310 COT John E. Smith, Gas City, Ind., assignor to Shelby Engineering Co., Inc., Indianapolis, Ind., a corporation of Indiana Filed Apr. 25, 1968, Ser. No. 724,032
Int. Cl. A47c 19/16 U.S. Cl. -111 6 Claims ABSTRACT 0F THE DISCLOSURE A cot or bed composed of five removable pieces which may be quickly and easily disassembled for storage in small areas, the device having no fitting or other movable parts which can wear out.
This invention relates to beds and more particularly to a completely collapsible cot.
It is therefore the main purpose of this invention to provide a cot which will have a pair of elongated tubular portions which will support a canvas portion between them.
Another object of this invention is to provide a cot which will have a pair of U-shaped members, each of which will be provided with swaged end for freely being received within the lower portions of the elongated members, thus providing a maximum rigidity for the structure of the cot and also allowing for easy disassembly of the cot for storage.
A further object of this invention is to provide a cot which will be of sufficient strength to support anyone while maintaining its rigidity and will have no fittings or other part which will wear out and will also be comfortable to the user.
Other objects of the present invention are to provide a cot which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and eflicient in operation.
These and other objects will become apparent upon a study of the following specification together with the accompanying drawing wherein:
FIG. 1 is a top plan view of the present invention;
FIG. 2 is a side View of FIG. 1 shown in elevation and partly broken away;
FIG. 3 is an end view of FIG. 2.
According to this invention a cot is provided with a pair of elongated tubular members 11 which are ice parallel with each other when a canvas web 12 is placed upon them. A tubular Ushaped member 13 forms the legs at each end of the cot 10 and members 13 are provided with swaged end 14 which easily slip into the lower extremities 15 of the elongated tubular members 11.
It will be noted that the U-shaped configurated tubular legs 13 in conjunction with the downward extending portions of the elements 11 form an extremely rigid construction thereby allowing cot 10 to support a person of substantial Weight without collapsing and cot 10 may be easily and quickly disassembled to form a neat and compact package for storage.
What I now claim is:
1. A cot comprising: a lirst pair of U-shaped continuous elongated tubular frame members, a flexible sheet carried by said frame members, providing support means for a person, a pair of floor engaging U-shaped tubular end members having ends receiving ends of said elongated frame members, providing rigidity and support means for said cot, said end members defining the opposite ends of said cot, the opposite ends of said sheet being spaced inwardly from the ends of said cot.
2. The combination according to claim 1 wherein: said frame members are disposed such that each forms an inverted U, the ends of said end members being swaged, and freely received and snugly retained in ends of said frame members.
3. The combination of claim 1 wherein: said frame members and end members are made of tubing of the same diameter.
4. The combination of claim 1 wherein: said frame members are free of fittings.
5. The combination of claim 2 wherein: the swaged ends of said end members are retained in the ends of said frame members by friction.
6. The combination of claim 4 wherein: said end members are free of fittings.
