55400680, Jul 30, 1996

Filed:

May 2, 1994

Appl. No.:

8/237258

Inventors:

Klaus W. Gartner - Palos Verdes Estates CA
Larry I. Cutter - Torrance CA
Peter I. Phillips - Lake Arrowhead CA

Assignee:

La Gard, Inc. - Torrance CA

International Classification:

E05B 4700

US Classification:

70277

Abstract:

An electronic combination lock is disclosed which allows access to a closed or secure location wherein the lock includes a locking mechanism for operating between a locked condition and an unlocked condition. A rotatable cam wheel has a circumferential surface portion defining a slot such that rotation of the cam wheel moves the slot. A movable lever 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 movable into and out of engagement with the cam wheel. The movable lever engages the cam wheel such that rotation of the cam wheel changes the condition of the locking mechanism. A cantilever and detent on the lever releasably maintain the lever in a position disengaged from the cam wheel. A solenoid and projectable detent 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.
