ABSTRACT:
The apparatus disclosed includes essentially a cot structure comprising, in combination, a folding frame having a flexible cover yieldable to body contour, and legs supporting said frame in displaced relation to a floor surface; said legs having a spring cantilever configuration and torsion residing in a single continuous bar member with opposite ends adapted to be received and held by said frame member; sockets so disposed in said frame member adapted to slidably receive the opposite ends of said leg bar members such that downward force on said legs secures the same in said sockets in rigid mode relative to said frame; hinges longitudinally disposed along the siderails of said cot structure as part of the same frame, said hinges each having a downwardly disposed pivot with upwardly disposed engaging interfaces, said interfaces engaging in occlusive buttress contact to distribute downwardly applied weight in a resolution of coherent force moments in optimum relation about said pivotal juncture for occupant support. Such structure achieves a buttress support platform integrated within the hinge as a joint knee to perfectly distribute the load to make the joint stronger with increasing weight.
