    摘要： A lock includes a housing, a keypad disposed on the housing, and a latch assembled with the housing. The keypad includes a plurality of button assemblies, each including an axially depressible button member including a camming surface, a lock wheel having a plurality of camming teeth, and a latch releasing feature secured to the lock wheel for rotation therewith. Pressing the button member causes the camming surface to engage one of the plurality of calming teeth, thereby incrementally rotating the lock wheel between a plurality of rotational positions. When the button members of a predetermined one or more of the plurality of button assemblies are depressed a predetermined number of times, the latch releasing features of each of the plurality of button assemblies align with a plurality of blocking features of the latch to permit lateral sliding movement of the latch from a locked condition to an unlocked condition.

    摘要： A combination lock for a key safe has an over-center spring for biasing a unitary bolt in an extended or retracted position. A switch for actuating the bolt has a break-away button to foil vandals. The bolt includes checkers for engaging notches in a plurality of programmable combination rings when the combination is properly dialed. The checkers have V-shaped ridges for engaging false notches formed in the combination rings, making the lock pick-resistant. The checkers also include flat shoulders to prevent the bolt from being forcibly wedged into the combination rings to open the lock. The combination must be properly dialed to permit the bolt to be retracted for closing the key safe.
