Abstract
A lever-handle lock includes a stationary support base adapted to mount to a door around a lever handle carried on the door. The lever-handle lock also includes a lever-handle rotation blocker mounted on the stationary support base to block selectively rotation of the lever handle relative to the stationary support base at the option of a user.
Claims22
A lock for a lever handle mounted on a door, the lock comprising
- a blocker-support base adapted to mount on a door in a fixed position to surround a lever handle coupled to the door and the blocker-support base is formed to include an anchor receiver,
- a lever-handle rotation blocker mounted on the blocker-support base to rotate about a rotation axis between a door-locking position wherein the lever-handle rotation blocker is adapted to block rotation about the rotation axis of a lever handle carried on a door to keep the door in mating contact with a door frame and a door-unlocking position wherein the lever-handle rotation blocker is adapted to allow rotation about the rotation axis of a lever handle carried on a door to allow the door to move out of mating contact with a door frame, and
- a blocker-movement controller including a rotation lock including an anchor and an anchor return configured to apply a biasing force to the anchor, the anchor being coupled to the lever-handle rotation blocker and configured to move from a lever-rotation blocking position wherein the anchor is arranged to extend into the anchor receiver formed in the blocker-support base toward a lever-rotation unblocking position wherein the anchor is positioned to lie outside the anchor receiver, and actuator means for moving the anchor against the biasing force to cause the anchor to move out of the anchor receiver to free the lever-handle rotation blocker to rotate about the rotation axis in response to rotation of the lever handle about the rotation axis from the door-locking position toward the door-unlocking position.
A lock for a lever handle mounted on a door, the lock comprising
- a blocker-support base adapted to mount on a door in a fixed position to surround a lever handle coupled to the door and the blocker-support base is formed to include an anchor receiver,
- a lever-handle rotation blocker including a barrier mount coupled to the blocker-support base to rotate about a rotation axis between a door-locking position and a door-unlocking position and a lever-handle motion barrier coupled to the barrier mount to move therewith, and
- a blocker-movement controller including a rotation lock coupled to the barrier mount and configured to move from a lever-rotation blocking position wherein the rotation lock is arranged to interconnect the barrier mount and the blocker-support base and a lever-rotation unblocking position wherein the rotation lock is positioned to lie outside the blocker-support base to cause the barrier mount to rotate about the rotation axis in response to application of a user-supplied torque to the lever-handle motion barrier and a rotation-lock actuator coupled to the lever-handle motion barrier to move relative to the lever-handle motion barrier.
A lock for a lever handle mounted on a door, the lock comprising
- a blocker-support base,
- a lever-handle rotation blocker mounted on the blocker-support base to rotate about a rotation axis between a door-locking position and a door-unlocking position, and
- an anchor coupled to the lever-handle rotation blocker and configured to move in a direction parallel to the rotation axis from a lever-rotation blocking position wherein the anchor is arranged to interconnect the lever-handle rotation blocker to the blocker-support base to a lever-rotation unblocking position wherein the anchor is positioned to lie outside the blocker-support base to cause the lever-handle rotation blocker to rotate about the rotation axis in response to application of a user-supplied torque to the lever-handle motion barrier.
