Redundant actuation lock decoupling system and methods of use
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.
1. A redundant actuation lock apparatus comprising:
a lock bar interface comprising a ramp and a stop, the lock bar interface configured to manipulate one or more lock bars into one of a locked position and an unlocked position;
an electronic lock mechanism comprising:
an actuator disengageably coupled to the lock bar interface, the actuator configured to drive the lock bar interface to manipulate the one or more lock bars, the actuator engaged to the lock bar interface in an electronic lock actuation mode, and the actuator disengaged from the lock bar interface in a manual key lock actuation mode, wherein the actuator comprises gear teeth configured to mesh with gear teeth of the lock bar interface to drive the lock bar interface; and
a power drive coupled to the actuator and configured to drive the actuator to drive the lock bar interface in response to a control signal; and
a manual key lock mechanism comprising:
a key input configured to receive a mechanical key, the key input rotatable with rotation of the mechanical key; and
a lock cylinder having a first end and a second end, the key input provided at the first end of the lock cylinder, the second end configured to disengageably couple to the lock bar interface, the lock cylinder rotatable with the rotation of the mechanical key at the key input,
wherein, in the manual key lock actuation mode, the lock cylinder is configured to:
slide across the ramp of the lock bar interface as the lock cylinder rotates to disengage the lock bar interface from the actuator, and
engage and drive the stop of the lock bar interface to manipulate the one or more lock bars, and
wherein, in the electronic lock actuation mode, the lock cylinder is disengaged from the lock bar interface.
2. The apparatus according to claim 1 , wherein the control signal is generated in response to a wireless signal transmitted by a mobile device.
3. The apparatus according to claim 1 , wherein the power drive rotates in a first direction to drive the actuator to drive the lock bar interface to manipulate one or more lock bars into the locked position.
4. The apparatus according to claim 3 , wherein the power drive rotates in a second direction to drive the actuator to drive the lock bar interface to manipulate one or more lock bars into the unlocked position.
5. The apparatus according to claim 1 , wherein the power drive is an electric motor.
6. The apparatus according to claim 5 , wherein the electric motor is a DC motor.
7. The apparatus according to claim 1 , wherein in the electronic lock actuation mode, the lock cylinder is disengaged from the ramp and the stop of the lock bar interface.
