Abstract
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. The two plates are then secured together by means of nuts that are threaded onto the studs of the outside plate. The plate mounted on the outside prevents one from manipulating the trunk latch by punching a hole in the trunk lid in the vicinity of the trunk lock and the inside mounted plate prevents one from gaining access to the trunk by the punching out of the lock cylinder.

Claim 1
Independent Claim
464 words
Apparatus for protecting a trunk lid and trunk lock of an automobile to prevent forceable entry into the trunk of the automobile comprising: a first protective plate made of a substantially heavy gauge metal, said first protective plate having a hole located substantially in the center thereof and having first and second threaded studs secured to one of its surfaces and projecting away from said surface, said first and second threaded studs being located on opposite sides of said hole and being spaced apart from said hole; a resilient washer having substantially the same size and shape as said first protective plate and having a substantially centrally located hole of substantially the same diameter as said hole in said first protective plate, said resilient washer further having first and second holes located on opposite sides of said substantially centrally located hole of said resilient washer and spaced apart therefrom, said first and second holes in said resilient washer being located relative to said substantially centrally located hole in said resilient washer such that said first and second studs of said first protective plate will pass through said first and second holes of said resilient washer with said substantially centrally located hole of said resilient washer being aligned with said substantially centrally located hole in said first protective plate; a second protective plate made of a substantially heavy gauge metal and having a substantially centrally located hole of sufficient diameter to permit said second protective plate to slip over the cylinder of said lock of said trunk lid and having first and second holes located on opposite sides of said substantially centrally located hole, said first and second holes in said second protective plate being so located relative to said substantially centrally located hole in said second protective plate that said first and second threaded studs will pass through said first and second holes of said second protective plate with the substantially centrally located hole in said second plate being substantially aligned with said substantially centrally located hole in said second plate when said first and second threaded studs are passed through said first and second holes in said second protective plate; and first and second nuts for securing said first protective plate to said second protective plate such that said first protective plate is located on the outside surface of said trunk lid and said second protective plate is located against the inside surface of said trunk lid with said cylinder of said lock of said trunk lid extending beyond said second protective plate into said trunk, said resilient washer being sandwiched between said outside surface of said trunk lid and said first protective plate, said first and second nuts being threaded onto said first and second threaded studs of said first protective plate.

Apparatus for protecting a trunk lid and trunk lock of an automobile to prevent forceable entry into the trunk of the automobile comprising: a first protective plate made of a substantially heavy gauge metal, said first protective plate having a hole located substantially in the center thereof and having first and second threaded studs secured to one of its surfaces and projecting away from said surface, said first and second threaded studs being located on opposite sides of said hole and being spaced apart from said hole; a resilient washer having substantially the same size and shape as said first protective plate and having a substantially centrally located hole of substantially the same diameter as said hole in said first protective plate, said resilient washer further having first and second holes located on opposite sides of said substantially centrally located hole of said resilient washer and spaced apart therefrom, said first and second holes in said resilient washer being located relative to said substantially centrally located hole in said resilient washer such that said first and second studs of said first protective plate will pass through said first and second holes of said resilient washer with said substantially centrally located hole of said resilient washer being aligned with said substantially centrally located hole in said first protective plate; a second protective plate made of a substantially heavy gauge metal and having a substantially centrally located hole of sufficient diameter to permit said second protective plate to slip over the cylinder of said lock of said trunk lid and having first and second holes located on opposite sides of said substantially centrally located hole, said first and second holes in said second protective plate being so located relative to said substantially centrally located hole in said second protective plate that said first and second threaded studs will pass through said first and second holes of said second protective plate with the substantially centrally located hole in said second plate being substantially aligned with said substantially centrally located hole in said second plate when said first and second threaded studs are passed through said first and second holes in said second protective plate; and first and second nuts for securing said first protective plate to said second protective plate such that said first protective plate is located on the outside surface of said trunk lid and said second protective plate is located against the inside surface of said trunk lid with said cylinder of said lock of said trunk lid extending beyond said second protective plate into said trunk, said resilient washer being sandwiched between said outside surface of said trunk lid and said first protective plate, said first and second nuts being threaded onto said first and second threaded studs of said first protective plate.
Claim 3
Dependent Claim
