发明名称 Door locking system
摘要 A lock guard system includes a shield which overlies the jamb face of a door in surrounding relation to the keeper recess in the jamb. The shield blocks insertion of a tool or device from movement toward the latch or lock bolt to be interposed between the lock latch and the keeper so such inserted device can be used to jimmy the latch out of the recess and thereby free the door from the jamb.
