Abstract
The present invention is a folding structure having an improved locking mechanism. In one embodiment, the folding structure comprises a plurality of legs and a hinge mechanism, the hinge mechanism comprising a plug hinge removably connected to a slider hinge between a first position at which the structure is substantially collapsed and a second position at which the structure is substantially open and the plug hinge is locked to the slider hinge. The hinge mechanism may further comprise a release cap engaged with the slider hinge and having a pair of buttons. Depression of the buttons unlocks or releases the plug hinge from the slider hinge, allowing the folding structure to be collapsed.
