Abstract
Methods and apparatus for using a look on a door lever handle are disclosed. The lock includes a base configured to mount the lock to a door having a lever handle and a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position. The lever handle guard is securable in the non-locking position. The lever handle guard includes first and second guard portions arranged to prevent rotation of the lever handle when the lever handle guard is in the locking position. When the lever handle guard is secured in the non-locking position, the first and second guard portions are arranged to permit rotation of the lever handle without contacting the first and second guard portions.

A lock for a door lever handle, the lock comprising:
- a base configured to mount the lock to a door having a lever handle;
- a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position, wherein the lever handle guard is securable in the non-locking position, the lever handle guard comprising:
- a first guard portion arranged to prevent rotation of the lever handle beyond a first rotation angle in a first direction when the lever handle guard is in the locking position;
- a second guard portion arranged to prevent rotation of the lever handle beyond a second rotation angle in a second direction when the lever handle guard is in the locking position, the second direction being opposite to the first direction;
- wherein, when the lever handle guard is secured in the non-locking position, the first and second guard portions are arranged to permit rotation of the lever handle in the first and second rotation directions beyond the first and second rotation angles without contacting the first and second guard portions.

- a base configured to be mounted to a door;
- a lever handle guard attached to the base, the lever handle guard being movable between a locking position and a non-locking position, the lever handle guard including:
- a first guard portion arranged to prevent rotation of the lever handle beyond a first rotation angle in a first direction when the lever handle guard is in the locking position;
- a second guard portion arranged to prevent rotation of the lever handle beyond a second rotation angle in a second direction when the lever handle guard is in the locking position, the second direction being opposite to the first direction;
- wherein:
- the lever handle guard is securable in the locking position;
- the first guard portion is movable closer to the second guard portion to unsecure the lever handle guard from the locking position.
