HIGH SECURITY ELECTRONIC DIAL COMBINATION LOCK
摘要:
An electronic combination lock (20) is disclosed which allows access to a closed or secure location wherein the lock includes a locking mechanism (36) for operating between a locked condition and an unlocked condition. A rotatable cam wheel (47) has a circumferential surface portion defining a slot such that rotation of the cam wheel moves the slot. A moveable lever (46) is coupled to the locking mechanism for changing the condition of the locking mechanism from the locked condition to the unlocked condition and is pivotably moveable into and out of engagement with the cam wheel. The moveable lever engages the cam wheel such that rotation of the cam wheel changes the condition of the locking mechanism. A cantilever (52) and detent (54) on the lever releasably maintain the lever in a position disengaged from the cam wheel. A solenoid (62, 98, 100, 106, 108, 110, 112) and projectable detent (96) moves the lever from its disengaged position for engaging the lever with the cam wheel so that rotation of the cam wheel changes the locking mechanism from the locked condition to the unlocked condition.
