ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a backpack that converts into a cot.
2. Description of the Prior Art
The present invention is a backpack which includes a suspension and a frame adjustably attached to each other by quick release pins. The backpack frame, which houses numerous storage bags and compartments, includes two support structures which are attached to each other by quick release pins. The support structures of the backpack frame can be realigned to form a frame for a cot. The suspension can be used without the frame and with one of the storage bags as a day pack.

However, none of these backpacks has an adjustable suspension or includes a frame that is oriented to give a mattress a great deal of stability.
U.S. Pat. No. 3,464,607, issued on Sep. 2, 1969 to Ernest Grace, teaches a backpack frame and suspension. However, it does not convert to a cot on its own (without the use of a second frame).
U.S. Pat. No. 3,885,722, issued on May 27, 1975 to Jerry Robertson teaches a backpack frame and suspension. However, it does not convert to a cot.
U.S. Pat. No. 3,912,138, issued on Oct. 14, 1975 to Norman Pava, teaches a backpack frame, suspension and plurality of storage bags or compartments, and it can be converted into a litter. However, it differs significantly from the present invention in its geometry and is designed for evacuating injured climbers and hikers, not for sleeping in comfort.
U.S. Pat. Nos. 3,733,017, issued on May 15, 1973 to Murray Pletz, 3,860,157, issued on Jan. 14, 1975 to Peter Richards, 4,169,550, issued on Oct. 2, 1979 to Paul Williams teach backpack frames, suspensions and plurality of storage bags or compartments. However, none of these designs can be converted to a cot.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.
SUMMARY OF THE INVENTION
The instant invention relates to a backpack which includes a suspension and a frame. The frame includes an inner support structure and an outer support structure releasably connected to each other by quick release pins. The backpack frame can house storage bags and compartments and is adjustably connected to the suspension system by quick release pins. By separating the two support structures, aligning them linearly to each other, and inserting elongated rods between them, a frame for a cot is formed. The orientation of the support structures is such that when a mattress is placed on the frame and weight is put on the mattress, the forces are directed inwardly, resulting in great stability. The suspension can be used as a day pack, i.e. the frame can be eliminated and one of the storage bags can be adjustably attached to the suspension.
Accordingly, it is a principal object of the invention to provide a backpack having a frame which can be converted into a cot.
It is another object of the invention to provide a backpack with a frame that can be adjusted with respect to a suspension system.
It is a further object of the invention to provide a backpack in which the suspension system can be used with and adjustably connected to a storage bag and without the weight of the frame.
Still another object of the invention is to provide a backpack that can easily be converted and adjusted by the use of quick release pins.
It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.
