U-shaped support legs are pivotally attached to the frame at each end and in the center.
Bottom Line Camping Tent Cots are a relatively new product in the market but which has revolutionized the camping adventures. The air acts as an insulation between yourself and the ground underneath you.
U-shaped support arms to support a flexible cover attached to the frame are pivotally connected to each end of the frame. The cot is foldable from an open, horizontal position where the legs and arms extend from the frame to a closed position where the support legs are positioned against the exterior of the frame and the support arms and cover are enclosed by the folded U-shaped frame members.
One important aspect of the cot structure is the provision of telescoping sides for each of the U-shaped frame members. In the retracted and folded position, the cot is quite compact and the cot structure is more readily transportable on a person''s back. In the open position, the U-shaped frames are fully extended so that the cot structure is of a length sufficient for a person to sleep therein.

Car campers who like to bring comfort and luxury to the wild should consider one of the sturdier cots with extra padding since they allow one to appreciate the extra comfort while sleeping. One point to note is that the thin cover has no built-in insulation.
Patent Office Classification Class , Subclass 5. Typical prior art units include U. These specifically enumerated prior art apparatus, while possessive of many advantages have many incon venient disadvantages. Typical disadvantages of a given prior art apparatus in general, are the lack of true portability because of weight and bulk by a single individual', non-unitary construction requiring the transportation of components separately which can be easily misplaced; lack of means to readily assemble and disassemble the unit; unstable support legs when the unit is utilized in soft terraimand difficulty in obtaining interior ventilation when occupied.
More specifically, the Barn apparatus U. The base legs are amenable to instability in soft terrain and the various elements which make up the cot and the support for the canopy are non-unitary and require field assembly. This field assembly is time consuming and there is always the risk of losing one of the detached elements which would render assembly impossible.
The Jensen apparatus U. Further, the Jensen appparatus has a rigid bed and a collapsible canopy arrangement utilizing a plurality of laterally oriented support arms. This apparatus is portable only in the sense that it can be transported with the canopy collapsed on a car top.
The Jensen apparatus is not portable in the sense that a single individual can readily carry the unit. Similarly, the Willis apparatus U. The recent patent to Moorhead et al. The McDougall patent is also primarily directed to a tent frame which is attachable to a conventional cot. The MacKenzie patent also shows a cot with a detachable tent or cover therefor. The tent portion of the MacKenzie device is quite complex and requires frame members, ropes and stakes for supporting the tent portion.
Accordingly, the art desires a true portable camping apparatus of unitary and compact construction which is readily amenable to assembly.
Such an apparatus is desired by those individuals who wish to carry a covered cot on their backs on camping trips, canoe trips, extended hikes and the like which have become increasingly popular today. It is another object of this invention to provide a portable camping apparatus which is stable in all types of terrain when occupied.
It is a further object of this invention to provide a stable, portable camping apparatus wherein the occupant can control ventilation from within. It is a specific object of this invention to provide a unitary covered camping cot employing a frame and canopy which is collapsible from an open position to a compact closed position suitable for transportation by a single individual.
