Convertible backpack and cot apparatus including a breakdown, rectangularly shaped, tubular cot frame including first and second pairs of frame elbow members forming the corners thereof and first and second pairs of tee devices connectable with the ends of the side runs of such elbow members. Side members connect on their opposite ends with the tee devices and crossmembers connect on their opposite ends with the confronting end runs of the elbow members. First and second U-shaped leg means are provided for connection on their opposite ends with the respective first and second pairs of tee devices and include respective pairs of leg elbow members which have their horizontal runs connected together by horizontal members. Thus, the cot frame may be assembled with a cot canvas stretched thereon and when camp is broken the cot frame may be knocked down and one pair of elbow members connected together on their respective one ends to form one end of a pack frame and the first pair of the devices connected to the opposite end of such one pair of elbow members, the horizontal members connected on their respective one ends with such first tee devices and the second pair of tee devices connected with the opposite ends of the horizontal members. A second pair of elbows may then be connected together on their respective one ends and connected on their respective opposite ends with the second pair of tee devices to form a backpack frame that is narrower in width than the cot frame.
A convertible and collapsible backpack adapted for shoulder support for persons to carry various types of loads on their backs while walking, said backpack being comprised of a pair of elongated J-shaped members of hollow tubular construction, said J-shaped members being conjoined by two mutually parallel collapsible bars extending in a perpendicular fashion from the middle portion of said J-shaped bars; said J-shaped members having on their respective axial lengths a plurality of holes extending therethrough which are capable of receiving therethrough a series of pins which lock onto corresponding positions on the respective J-bars the fastening ends of various carrying members such as a baby pouch, or a knapsack support, or alternately, a tray member for eating meals when at rest.
A backpack frame of the type including an upper U-shaped frame extension is convertible to a chair through the use of a lightweight conversion assembly including a pair of seat tubes demountably attached to the pack frame to divide the same into chair back and rear leg portions. The seat tubes carry a simple sling-type seat of canvas or the like and the opposite ends of the seat tubes are adapted to receive the free ends of the U-shaped frame extension which is removed from the backpack frame to provide the front legs of the chair. The entire conversion assembly is very light and occupies little space and can, therefore, be readily carried in the usual backpack attached to and used with the frame.
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.
A backpack including a tubular frame whose ends are extensible to elongate the frame to form a cot. A canvas cover on the backpack frame is also extended to serve as a support for the body of the user on the frame and is attached to the extended frame portion.
A combination pack and cot is provided by using a pack frame comprising detachable U-shaped members which serve as the legs of the cot by supporting rods fitting into notches. The pack canvas can also serve as the cot webbing.
