초록 ▼

A protective cover is provided for a handle lock. The handle lock includes a handle housing, a closure handle, and a lock mechanism. The housing includes a tubular receptacle extending into a door or other closure, and a lateral flange on the receptacle supporting the housing on the outer surface of the closure. The closure handle has a stem received in the receptacle and a grip on the outer end of the stem, the handle being movable inwardly and outwardly with respect to the housing between an inner locked position wherein the grip is adjacent to the flange, and an outer operating position. The lock mechanism is carried by the handle and is cooperative in the locked position with structure on the housing, for locking the handle to the housing. The protective cover includes a mounting plate having an opening receiving the receptacle therethrough, while the flange secures the plate to the closure, and a casing mounted on the plate and continuously surrounding the flange and the grip in the locked position. The casing has a handle-movement opening permitting movement of the handle between the locked and operating positions, the grip being disposed outwardly of the casing in the operating position. The casing lies closely adjacent to the grip around the periphery of the handle-movement opening in the locked position. The cover prevents prying on the grip and thwarts any attempt to defeat the lock in this manner.
