ABSTRACT:
A support mechanism wherein two rods or bars are pivotally connected to pit folding. A slot is provided in one bar at the pivot pin and a spring latch is provided in the other bar near the pivot pin. The bars are attached at the extreme ends to other items. When fully extended, this mechanism can support an item such as a heavy hood in a double-positive fashion by automatic simultaneous engagement of both locking devices. The mechanism can also be stored in minimum space by releasing the locks and folding.
