2 Claims.

1 This invention relates to new and useful improvements in sleepin cots, and it is among the objects thereof to provide a cot that will be collapsible and in which the several parts may be separated and packed in categorical groups,

whereby a large number of such cots may be transported in a relatively small space.

A further object of th invention is to provide a canvas cot in which the legs are loosely joined to the horizontal supports without any connecting means.

Still another object of the invention is the provision of a canvas cot in which the structural elements are interlockingly held by the canvas body being stretched and secured in position.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which like reference characters designate like parts, and in which Fig. 1 is a top plan View of a collapsible cot embodying the principles of this invention;

Fig. 2 a side elevational view thereof;

Fig. 3 a view in perspective of a corner post and portions of the canvas supporting frame; and

Figs. 4, 5 and 6 are top plan views, respectively, of portions of the cot in various stages of assembly.

With reference to the several figures of the drawing, the numeral I designates a heavy textile fabric, such as canvas, having tubular scams 2 sewn at the sides and one end thereof for receiving iron pipes or tubes 3 and 4, one end of the canvas having its corners folded over and sewn to provide an edge trim for the side and end tubular seams through which the side tubes 3 and end tube A project. The cot frame consists of the iron pipes 3, 3a and 4a and legs 5 shown in Figs. 2 and 3, the legs consisting of a piece of pipe about a foot long having a pipe cap 5 screwed on the end and having an angle bar I welded or otherwise attached to the top of legs 5 at 8, the angle bar bein round rod of a size to fit in the opening 9 of the tubing constituting the side and end frames.

The structure is assembled and secured as follows. As shown in Fig. 4, the side rods 3 and 3a are inserted in the tubular scams 2. The end rod l is then inserted in the tubular seam 2a. Two of the feet or legs 5, with the angle bar 1, are inserted in the end tube 6 as shown in Fig. 5, and the tubes 3 and 3a are then moved forward to receive the ends of the angle bar 1 as shown in Fig. 6. The end tube Ga with its legs and angle bars assembled as shown in Fig. 6 is then brought into position by moving it in the direction shown by the arrow until the angle bars I are fitted into the ends of the side tubes 3 and 3a.

The free end of the fabric is then secured to the end tube ea by means of a rope, such as sash cord 16, which is laced through grommets ll, of which five are shown, and drawn up tightly and fastened to the frame. The length of the canvas is less than the length of the assembled pipe members, leaving a clearance space designated by the numeral i2, Fig. 1, so that by stretching the cot material or canvas, tension is applied to all of the corner joints, whereby they are securely held in their assembled position, there being no other fastening means or connectors used.

The structure may be dismembered by simply untying the sash cord iii and pulling out the end member is, after which the other metal parts are easily removed. It is apparent that the simplicity of the structure lends itself to speedy as-- sembly of the parts, and by the several parts being disjointed they may be packed in barrels and the fabric portion folded so that several hundred of such cots can be transported in a single truck for mass Boy Scout outings and the like.

Although one embodiment of the invention has been herein. illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of con struction without departing from the principles herein set forth.

1 claim:

1. A collapsible cot comprising a flexible sheet having tubular seams at both longitudinal and one transverse side, pipes disposed in said tubular seams, corner posts having angle pieces loosely engaging the ends of said pipes, a pipe disposed outside said sheet at the other transverse side engaging the angle pieces of a pair of said corner posts, and means tying said sheet to said last named pipe to thereby interlock all of said pipes and posts.

2. A collapsible cot comprising a flexible sheet having tubular seams at both longitudinal and one transverse edge thereof, pipes disposed in said seams, angle brackets disposed in the ends of said pipes, said brackets having legs for supporting the cot structure, and a pipe disposed outside of said sheet engaging a pair of angle brackets, said sheet having ties for fastening to said last named pipe whereby said pipes and brackets are interlocked as a unitary cot structure.
