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.

Abstract: Methods and apparatus for using a gate latch to selectively prevent the opening of a gate barrier. The gate latch includes a retainer assembly to selectively prevent a latch member attached to a gate barrier from moving sufficiently to allow the gate barrier to swing open. A swing blocker may be provided on the same latch as the retaining assembly so that the gate may be opened only in a first direction.
