Anti-theft device

1. An anti-theft device for use in deterring theft of an audio/video device mounted to a bracket, which includes:

a female housing portion having a recessed channel surface extending from a first side inwardly defined by an upwardly extending side surface and a laterally connecting surface through which a bolt receiving opening extends entirely through to an outer side of said female housing portion, said laterally connecting surface further includes a first lock pin receiving surface extending at least partially into said female housing portion,

a male housing portion having a protruding surface of a complementary configuration to be slidably received against said recessed channel surface, and having an outwardly extending side surface and a laterally connecting surface which respectively mate to the upwardly extending side surface and laterally connecting surface of said female housing portion when mated to one another, and a second lock pin receiving surface extending at least through said male housing portion and which is coaxially aligned with said first lock pin receiving surface when said female housing portion and male housing portion are mated, and

a push button cam lock disposed in said male housing portion having a lock pin and an operably connected keyed portion which in a non-actuated position permits mating of said male housing portion to said female housing portion when so mated and upon actuation enables movement of said lock pin to an extended position through said first and second lock pin receiving surfaces thereby preventing movement between said female and male housing portions, wherein an outer surface of said female housing portion includes a plurality of inwardly extending holes to selectively removably receive a spring pin which is used to seat in a bracket slot and prevent rotation of the anti-theft device.

2. The anti-theft device of claim 1 , wherein when said male and female housing portions are mated, said male housing portion and said female housing portion provide an external polygonal configuration having two sides which intersect by a line and which collectively form an angled peak above the bracket when connected thereto and positionally fixed relative to the audio-video device to deter easy access to cut or break the same.

3. The anti-theft device of claim 1 , which includes a key operably keyed to said push button cam lock.

4. The anti-theft device of claim 1 , which includes a bolt having a head and a neck which is threaded in a manner to enable securing to a bracket of the audio/video device, said neck extending through said bolt receiving surface and said head retained between the laterally connecting surfaces when said female and male housing portions are mated.

5. The anti-theft device of claim 4 , which includes washers provided on each side of said bolt receiving surface of the female housing portion and to receive the bolt neck therethrough.

6. The anti-theft device of claim 1 , wherein said inclined surfaces of said female and male housing portions provide for a dovetail fit therebetween.

7. An anti-theft device for use in deterring theft of an audio/video device mounted to a bracket, which includes:

a female housing portion having a recessed channel surface extending from a first side inwardly defined by an upwardly extending side surface and a laterally connecting surface through which a bolt receiving opening extends entirely through to an outer surface of said female housing portion, said laterally connecting surface further includes a first lock pin receiving surface extending at least partially into said female housing portion,

a male housing portion having a protruding surface of a complementary configuration to be slidably received against said recessed channel surface, and having an outwardly extending side surface and a laterally connecting surface which respectively mate to said upwardly extending side surface and laterally connecting surface of said female housing portion when mated to one another, and a second lock pin receiving surface extending at least through said male housing portion and which is coaxially aligned with said first lock pin receiving surface when said female housing portion and male housing portion are mated, and

a push button cam lock disposed in said male housing portion having a lock pin and an operably connected keyed portion which in a retracted position permits said male housing portion to be slidably received adjacent said female housing portion and upon actuation enables movement of said lock pin to an extended position through said first and second lock pin receiving surfaces thereby preventing movement between said female housing portion and said male housing portion, wherein an outer surface of said female housing portion includes at least one inwardly extending hole to selectively removably receive a spring pin which is used to seat in a bracket slot and prevent rotation of the anti-theft device.

8. The anti-theft device of claim 7 , which includes a key operably keyed to said push button cam lock.

9. The anti-theft device of claim 7 , which includes a bolt having a head and a neck which is threaded in a manner to enable securing to a bracket of the audio/video device, said neck extending through said bolt receiving surface and said head retained between said laterally connecting surfaces when said female and male housing portions are mated.

10. The anti-theft device of claim 9 , which includes washers provided on each side of said bolt receiving surface of said female housing portion and to receive said bolt neck therethrough.

11. The anti-theft device of claim 7 , wherein said inclined surfaces of said female and male housing portions provide for a dovetail fit therebetween.
