Abstract

Abstract The lock housing has a slot in a top wall via which a coded card key can be inserted to bring into alignment coded magnetic areas on the card with magnetically responsive elements of the lock to unlock the locking mechanism and enable rotation of either a knob or lever arm to open the door. The card moves a spring actuator against a coupling spline to engage it with a spindle spline carried by a shaft interconnected with the knob or lever arm handle. The sliding coupling spline is integral with parts which interrelate with the door lock mechanism such that rotation of the knob or lever arm will now effect release of the door locking mechanism. When the card is fully inserted, the mechanism is maintained in the unlocked condition and the card may be released to turn the knob or handle with the same hand. Spring-loaded members separate the coupling and spindle splines as the magnetic card key is withdrawn from the housing slot. Once the internal lock mechanism is unlocked, it is maintained unlocked until the magnetic card has been withdrawn from the lock housing.
