| The invention relates to a foldable chair having a back support which is pivotally connected to a seat support and arm rests which are pivotally connected to the back support and adapted to be rotated into a position in which they form a ground support for the back support when the latter is in a swung down extended position for forming a bed. | ||||||

| A convertible backpack and cot apparatus includes an extensible unitary frame which in its contracted condition is of a convenient size to carry on the back of a user and in its extended condition forms the peripheral framework of a cot and includes legs for retaining the peripheral framework elevated from the ground. The frame is composed of telescoping side and end portions so that the frame can be extended both in a lateral and longitudinal direction. Each end portion carries a supporting leg that is rotatable between fixed positions so that the leg can also serve as a support for a bedroll or the like or as an attachment bar for shoulder straps when the apparatus is used as a backpack. A center leg interconnects the side portions of the frame and is extensible laterally of the apparatus to provide an intermediate support when the apparatus is used as a cot. The frame is adapted to carry a conventional knapsack, and a cot sheet is connected along its periphery to the frame so as to be stretched taught when the frame is extended.

| 83 | Modular cradle-like structure | US34047773 | 1973-03-12 | US3837019A | 1974-09-24 | HOFF J |
| A modular cradle-like structure in which a frame, detachably built up from tubular members and socketed couplings, and having bowed triangular ends joined in spaced parallel alignment by spacers connecting aligned sides of said triangles at approximately their mid-points, provides suspending means for a unitary body support, said body support being formed of flexible sheet material having generally traingular end pockets for engagement with upwardly oriented apexes of said triangular ends, and means along opposed edges intermediate said pockets for detachably securing the same to the two upwardly oriented spacers. Whether produced as a small, infant cradle device, or a large adult camping or emergency sleeping unit the modular construction of the frame and flexible body support permits stowing of the disassembled parts in a minimum of space.

| 84 | Portable foldable cot | US3757360D | 1971-08-16 | US3757360A | 1973-09-11 | WESCOTT J |
| A portable, folding cot in which a pair of rectangular-shaped support members, which support the ends of the cot, may be pivotably coupled together at one end and secured at the other end to provide a transportation enclosure for the structural members comprising the cot. A plurality of elongated rigid support members, T-shaped coupling members, and X-shaped legs are joined together to support the cot, in conjunction with the end members, during use. A tent supporting structure may be provided, if desired.
