Abstract
A lock mechanism has a locked condition and an unlocked condition and includes a housing. The lock mechanism also includes a latch that extends from the housing and has an extended position and a retracted position. The lock further includes a biasing member for biasing the latch to the extended position. The lock mechanism further yet includes a means for transferring an operator input motion to move the latch to the retracted position in the unlocked condition. The means for transferring an operator input motion includes uncoupling the operator input motion from the latch in the locked condition. The means for transferring also includes a locking driver and a locker. The locking driver includes a first surface and a second surface and the locker includes a biasing member for biasing the locker toward at least one of the first and second surfaces.
