Abstract
A ladder may include a first pair of spaced apart members, a second pair of spaced apart members and a first pair of hinges coupling the first pair of spaced apart members with the second pair of spaced apart members. In some embodiments, each hinge may include a first hinge component including at least a first hinge plate, the first hinge plate having a notch formed therein, the notch including a first abutment wall and a second abutment wall, a second hinge component including at least a second hinge plate, and a lock mechanism having a pivot pin and a lock pin. The lock mechanism is configured for selective engagement with the notch such that the pivot pin engages the first abutment wall and the lock pin engages the second abutment wall to lock the first hinge component relative to the second hinge component in a first hinge position.
