  • Patent number: 4114410
    Abstract: The invention relates to an improved device for opening a lock and a means for actuating the device. The device is characterized by a moving plunger or rotating wheel which is provided with slots which mesh with at least two rocking tumblers which engage the slots when they are biased by a reference card and thus prevent movement of the plunger or wheel. The rocking components can be disengaged from the slots when they in turn are biased by the proper keycard, thereby freeing the plunger or wheel and allowing operation of the mechanism of the lock.
