ABSTRACT:
A lightweight assembly weighing less than 10 pounds is provided for enabling a person who is living out of doors to sleep off the ground, and to have suitable shelter against the elements. The assembly is made up of two principal parts, the first being a pack frame which is to be secured to a person's back, and the second being the lightweight tubular folding structure which form the cot and the remainder of the tent support. The pack frame portion of the assembly is of generally A-frame configuration with a recessed frame to avoid contact with a person's back, and having two adjustable padded horizontal straps to engage the wearer's back. Additional frame members extend along the side and encompass the rear of the pack frame behind the actual pack per se, which may be of conventional configuration. The lower suspension points for the shoulder straps is underneath or to the rear of the center of gravity of the pack frame and pack assembly, and the resultant configuration reduces the pressure on the lower back of the user, as compared with conventional pack frame arrangements.
