发明名称 Latch guard
摘要 A latch guard is secured to the surface of a door to which a door's latching mechanism is secured and therefore cannot be removed when the door is in a closed position. The latch guard comprises a latch bolt tumbler, a face plate integrally formed with the latch bolt tumbler, and a protection bar formed integrally with the face plate. The face plate aligns with the surface of the door and therefore is acceptable for use with door and door frame combinations having little clearance there between. According to another aspect of the invention, a latch guard system comprises a latch guard and a strike plate. The strike plate has a recess area formed therein to accommodate the latch guard when the door is closed upon the door frame.
