PORTABLE FOLDABLE cor The present invention relates to portable cots, and in particular to a light-weight, foldable, portable cot which may be transported in a container formed by a pair of support members which support the ends of the cot during use and may be pivotably coupled together at one end, and secured together at the other end, to enclose the structural members of the cot.
Conventional portable cots consist of a plurality of detachable and foldable members. They are very cumbersome and awkward to carry, especially on camping trips or excursions through wooded areas or mountains where most of the travelling is done on foot. These cots are not able to be packed into a compact container so that they can be easily transported.
Accordingly, the present invention provides a portable, foldable cot in which a canvas sheet, having a plurality of elongated slots provided at the periphery thereof, is supported by a plurality of elongated, rigid lateral support members disposed through the slots provided in the sheet of material. The ends of the support members have cylindrically-shaped recesses, which slidably receive cylindrical rods affixed to the ends of a plurality of pivotable coupling members. The coupling members are substantially T-shaped, and are provided with a pair of pivotable arms affixed thereto and a rectangular-shaped, hollow projecting member affixed to the coupling member perpendicular to the pivotable arms. A pair of rectangular-shaped end support members are connected to the lateral support members to support these members and the sheet of material during use. A pair of foldable support legs, having their ends disposed in the rectangular recesses provided in the coupling members, support the cut at selected points along its length. The legs comprise a first integrally formed support member, and a pair of second support members, rigidly affixed to a rigid mounting member, which is pivotably coupled to the first support member. The ends of the second leg support members abut the top and the bottom surfaces of the first member and thereby lock the legs in an open, X-shaped position to support thecot. A pair of rigid, elongated separation members, having V-shaped notches provided in the ends thereof, are disposed adjacent the end support members between the lateral support members to insure the separation thereof during use. The end support members are provided with U-shaped hinges for detachably and pivotably coupling the ends of the frame members together, and'fastening clips disposed .on the other end of the end members to secure the end support members together during transportation of the cot. A tent-support structure may also be provided, if desired. The end frame members may also be provided with a pair of shoulder straps, for carrying the folded cot on the user's back, or a handle, provided on the side surface thereof, for. carrying the cot by hand. f
It is therefore an object of the present invention to provide a foldable, portable cot, whose structural mem bets are completely contained within a compact container formed by structural members of the cot.
It is also an object of the present invention to provide a foldable, portable cot, which may simply and easily 7 be provided with a tent.
It is a further object of the present invention to provide a foldable, portable cot, which is simple in design, easy to manufacture, and reliable in operation.

Referring to the drawings, FIGS. 1-6 illustrate a portable,-foldable cot havingrectangular-shaped end support members 10 provided with a'plurality of ovalshaped apertures 11. The end support'members support elongated lateral support members 12 which have an L-shaped mounting member 13 rigidly fixed to the endthereof. Three lateral support members are provided for each side of the cot, one at each end and one disposed between coupling members 17. The mounting members are connected to end members 10 by a bolt and wing nut fasteners 14,. and are disposed at an angle to increase the load-bearing capacity of the'cot. A rivet 15, or other suitable fastening means, is disposed through member 12 and affixed to member 13 in order to secure the mounting member thereto.
Canvas cot 16 is provided with slots at the periphery thereof for receiving the lateral support members of the 'cot. Coupling members 17 are substantially T-shaped and have a pair of pivotable arms 18 affixed thereto.
The arms are provided with cylindrical members 19 affixed to the ends thereof, which are received in recesses 20 provided in lateral support members 21 to support the sides of the canvas. A hollow, rectangular-shaped projecting member 21 provided on the coupling members receive the ends of the cot legs 22. Separation members 23 have V-shaped notches provided in the ends thereof and are disposed between the ends of members 12 so that the lateral support members of the cot are securely held apart during use.
As shown in detail in FIGS. 4 and 5, legs 22 of the cot consist of a pair of pivotably coupled support members which are pivotably secured at 24 by a rivet or other suitable fastening means. Leg 22a is integrally formed so as to comprise a single member, while the second leg comprises individual members 22b and 22c, and metallic mounting member 25, which rigidly connects the leg members to form a single support leg. Rivets 26 secure members 22b and 220 in member 25 so that when the legs are pivoted to their open position, the ends of the legs abut leg 22a and secure the legs in the illustrated X-shaped position to support the cot during use. The legs may be folded towards each other to assume a closed position adjacent one another as shown in FIG. 10.
The cot may also be provided with a tent supporting structure consisting of vertically disposed support members 27 which have the end portions thereof disposed horizontally, perpendicular to the vertical portions thereof so as to slide into an aperture provided in the ends of supporting members 12. The vertical support members are coupled by horizontal members 28, which are secured to members 27 by means of wing nuts 29 and 31. A plurality of pivotably coupled, elongated rectangular-shaped rods 30 are coupled to members 27 and 28 by wing nuts 31 and have support rivets 32 disposed perpendicular to rods 30 at the pivotable coupling points thereof, thereby providing a rigid tent structure for supporting the tent. Rods 30 are pivotably coupled together by means of rivets 33 as shown in FIGS. 7, 8 and 9, and are provided with offset rectangular-shaped slots 34 through which theends of cross members 32 are disposed. The ends of members 32 are T-shaped and are provided with a notch 35. When members 32 are disposed through slots 34, notch 35 receives members 32. When the members are aligned, slots 34 are offset; when they are nonaligned, the slots are aligned, thereby allowing removal of members 32.
. When the slots are offset, as shown in FIG. 8, members 32 are held securely in place and rigidly secure the tent structure. To remove the cross rib members, members 30 are moved until slots 34 are in exact alignment. Cross rib member 32is then turned until the flat surface of the cross rib member is parallel to the slots, whereupon members 32 may be slidably removed.
As shown in FIG. 10, when the portable cot is disassembled all of the structural members thereof fit within end support members and may be carried easily therein. The end members are provided with U-shaped hinges 36 attached to one end thereof. These hinges uncouple from one another when the end members are pivoted to the position shown in FIG. 10, i.e., when the members are in 180 alignment. Clips 37 affixed to the other ends of the end members secure the members in their closed position to prevent the opening of the case during transportation of the cot. A pair of shoulder belts 38, or a handle 39, may be provided on end members 10 to provide for easy carrying of the cot. If shoulder belts are used, a T-shaped member 40 is secured in an elongated slot provided in end member 10, as shown in FIG. 2. The cot can then be easily carried on the back of the user. Either the shoulder belts, or the handle, or both, may be provided on the end members, as desired.
A collapsible rack consisting of U-shaped member 41 having cross-bar 42 pivotably coupled to members 43 may also be provided. If the rack is desired to be used, members 43 are bent inwardly towards each other out of cylindrical retaining slots 44 and transferred to cylindrical retaining slots 45 provided on a lower portion of end member 10. The rack will then assume the position shown in FIG. 11 and be available for use for carrying, for example, extra camping supplies. When not being used, the rack is retained out of the way flat against the back of end member 10.
As shown in FIGS. 12 and 13, the portable cot shown in FIG. 1 may be covered with a canvas tent 46. Additional support members "are provided to support an additional shelter flap for the user. Two of the tents shown in FIG. 12 may be placed together to form the larger tent shown in FIG. 13.
All the structural members comprising the portable cot are preferably constructed of light-weight metallic materials, such as aluminum. Conventional wood members, however, may be used for the support members of the cot, if desired.
To use the cot, the user unclips clips 37 and pivots members 10 apart to the position shown in FIG. 10, whereupon hinges 36 will separate. After the support members, coupling'members and separation members are inserted in the slots provided in canvas 16, and coupling members 17 inserted into the recesses provided in the lateral support members, mounting members 13 are attached to end members 10 by means of wing nuts 14. Legs 24 are then unfolded and inserted into projecting members 21 to support the cot. The tent structure may then be added if desired, and the tent disposed thereon by the user.
While only several embodiments of the present invention have been shown and described, it will be un-.
derstood by those persons skilled in the art that'many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
