US 12,467,280 B2 · Redundant actuation lock decoupling system and methods of use

Abstract

A redundant actuation lock apparatus includes an interface, an electronic mechanism, and a manual mechanism. The interface manipulates lock bar(s) into a locked/unlocked position. The electronic mechanism includes an actuator and power drive. The actuator is disengageably coupled to and drives the interface. The power drive is coupled to and drives the actuator in response to a control signal. The manual mechanism includes a key input and an output. The key input receives and rotates with a mechanical key. The output disengageably couples to the interface and rotates with the mechanical key. The actuator is engaged with and the output is disengaged from the interface in an electronic mode, while the actuator is disengaged from and the output is engaged with the interface in a manual mode.

Dependent claims

A method of operating a redundant actuation lock apparatus in a manual key lock actuation mode, the redundant actuation lock apparatus having a lock bar interface configured to manipulate one or more lock bars from a locked position to an unlocked position and from the unlocked position to the locked position, the method comprising:

receiving a rotation of a mechanical key at a key input in a manual key lock actuation mode, wherein the key input rotates with the mechanical key;
disengaging an actuator from the lock bar interface based on the rotation at the key input, the actuator configured to drive the lock bar interface in an electronic lock actuation mode;
rotating a lock cylinder output from a location between locked and unlocked positions with the rotation of the mechanical key at the key input to engage an interlock of the lock cylinder output with a lock bar gear head of the lock bar interface;
driving the lock bar interface based on the rotation of the lock cylinder output having the interlock that interfaces with and drives the lock bar gear head of the lock bar interface;
and
moving the one or more lock bars, by the lock bar interface, to one of the locked position and the unlocked position.
