ABSTRACT:
A lockable hinge includes a first and second hinge member, a lock, and an actuator. The lockable hinge is coupled to a pair of ladder-leg sections and is arranged to allow the ladder-leg sections to move among closed-ladder, trestle-ladder, and straight-ladder positions. The lock is used to lock the hinge members to cause the ladder-leg sections to lock in the closed-ladder, trestle-ladder and straight-ladder positions.
