Paddle handle locks for securing push-pull, paddle-style door latches. In a first preferred embodiment the paddle handle lock is characterized by a handle lock having a frame with parallel side plates separated by spacers and fitted with a clamp arm pivotally attached to one of the spacers. Registering frame pilot holes and clamp arm pilot holes facilitate locking the clamp within the frame, such that the respective spacers prevent movement of the paddle door handle upon which the handle lock device is mounted. The padlock can be removed to allow pivotal extension of the clamp arm and manipulation of the door handle or removal of the handle lock from the door handle, to render the door latch operable. In another preferred embodiment a lockset handle lock is provided which includes a cylinder lock mounted in a lock housing and fitted with a pivoting clamp arm, one end of which clamp arm extends into the lock housing and engages a conventional cylinder bolt on the lock cylinder. The clamp arm normally engages the door handle to maintain the door handle in inoperable condition. However, upon manipulation of a key and the cooperating cylinder, the clamp arm is disengaged from the cylinder bolt and may be pivoted upwardly to disengage the door handle and render the door handle operable.
A handle lock for a push-pull, paddle-type door latch having a base and a paddle handle pivotally attached to the base, said handle lock comprising a pair of frame plates and frame spacer means separating said frame plates, said frame spacer means spanning said base and said frame spacer means also engaging said paddle handle when said handle lock is in locked configuration and clamp arm means pivotally carried by said frame plates, whereby said clamp arm means is pivotally disposed between said frame plates and engages the paddle handle when said handle lock is in the locked configuration and said clamp arm means is pivotally extended from said frame plates and disengages the paddle handle when said handle lack is in the unlocked configuration.
A handle lock for locking the paddle handle of a push-pull, paddle-type door latch having a base and a paddle handle pivotally attached to the base, said handle lock comprising a frame characterized by a pair of spaced-apart frame plates, a pair of top frame spacers connecting said frame plates, with said top frame spacers for engaging said base and selectively engaging said paddle handle, respectively;
A lockset handle lack far a push-pull, paddle-type door latch having a base and a paddle handle pivotally attached to the base, said lockset handle lock comprising frame means configured to selectively engage the paddle handle and seat on the base;
