  • Automobile trunk guard
    Patent number: 4041741
    Abstract: Protective plates for protecting against two common methods of breaking and entering an automobile trunk are disclosed. One plate is mounted on the outside of the trunk lid and the other plate is mounted on the inside of the trunk lid. The plate mounted on the outside of the trunk lid protects the trunk lid in the immediate area of the trunk lock. The plate mounted on the inside of the trunk lid protects against forceable removal of the lock cylinder. The plate that is mounted on the outside of the trunk lid surrounds the trunk lock and has a central opening to permit access to the trunk lock. Two threaded studs secured to this outside plate pass through holes drilled in the trunk lid and through holes provided in the plate that is mounted on the inside of the trunk lid. The plate mounted on the inside of the trunk lid has a central opening and is slipped over the trunk lock cylinder and over the two studs of the outside mounted plate.
