Abstract
A lock assembly for use with a powered actuator includes a housing, a first barrel part, a torque transmitting member, a first cam, a drive device and a spring. The housing has at least a first axially extending recess therein. The first barrel part is within the first recess. The torque transmitting member is adapted for abutment and releasable rotational engagement with a key. The first cam is adapted to operate a lock or latch mechanism and for rotational movement with the torque transmitting member. The drive device is adapted for engagement with the powered actuator and releasable engagement with the torque transmitting member. The spring biases the torque transmitting member towards engagement with the drive device.
Claims32
A lock assembly adapted for use with a powered actuator, the lock assembly comprising:
- a housing with at least a first axially extending recess therein;
- a first barrel part within the first recess, the first barrel part having a first end and a second end, the first barrel part extending between the first end of the first barrel part and the second end of the first barrel part;
- a torque transmitting member adapted for abutment and releasable rotational engagement with a key;
- a first cam disposed around the first barrel part between the first end of the first barrel part and the second end of the first barrel part, the first cam adapted to operate a lock or latch mechanism and for rotational movement with the torque transmitting member;
- a drive device disposed around the barrel part and between the first end of the first barrel part and the second end of the first barrel part, the drive device adapted for engagement with the powered actuator and releasable engagement with the torque transmitting member;
- and
- a spring biasing the torque transmitting member towards engagement with the drive device, and
- wherein the torque transmitting member is positioned between the drive device and the first cam and is adapted to transmit torque from the drive device to the first cam, and
- wherein the absence of a key in the first barrel part allows the torque transmitting member to be moved by the spring into engagement with the drive device whereby pivoting movement of the drive device causes corresponding pivoting movement of the cam, and
- further wherein a key in the first barrel part engages and abuts the torque transmitting member and moves the torque transmitting member out of engagement with the drive device whereby pivoting movement of the key causes corresponding pivoting movement of the cam.
A lock assembly adapted for use with a powered actuator, the lock assembly comprising:
- a housing with at least a first recess axially extending therein;
- a first barrel part within the recess and having a key slot, the first barrel part having a first end and a second end, the first barrel part extending between the first end of the first barrel part and the second end of the first barrel part;
- a movable torque transmitting member substantially within the recess;
- a cam adapted for rotational movement with the torque transmitting member;
- a drive device positioned within the first end of the first barrel part and the second end of the first barrel part and adapted for engagement with the powered actuator;
- and
- a spring biasing the torque transmitting member towards the drive device;
- wherein the torque transmitting member is positioned between the drive device and the cam and is adapted to transmit torque from the drive device to the cam, and
- wherein the torque transmitting member is adapted for pivoting movement with the key and independent of the drive device when a key is inserted into the key slot, and for engagement and corresponding pivoting movement with the drive device when the key is removed from the key slot.
