ABSTRACT:
A manual lock for a vertically storing lock leveler. The leveler has a locking bar on the side thereof which rides on a cam surface of the lock. The lock has a spring biased latch member with the cam surface and a locking recess. When the leveler is in the vertical stored position, the latch overtravels to have the lockbar engaged in the recess so that positive locking occurs. The lock is released by a manual foot or hand release.
