Abstract

A security system for confining movement of an object to a predetermined area. The security system has a cable, with a length, and a housing. The housing is guidable slidingly along the length of the cable and capable of being fixed at a plurality of different locations spaced along the length of the cable. The cable has a first portion that can be fixed relative to the housing. With the first portion fixed relative to the housing, the cable defines a loop with an effective diameter that is variable by sliding the housing along the length of the cable. The cable has a second portion that can be secured to a support relative to which an object is to be confined by the securing system.

Claims

1. In combination:

a) a security system for confining movement of an object to a predetermined area, the security system comprising;

a cable having a length; and

a housing,

the housing guidable slidingly along the length of the cable and capable of being fixed at a plurality of different locations spaced along the length of the cable,

the cable having a first portion that can be fixed relative to the housing,

whereby with the first portion fixed relative to the housing, the cable defines a loop with an effective diameter that is variable by sliding the housing along the length of the cable,

the cable having a second portion, spaced from the loop, that is secured to a support relative to which an object is to be confined by the security system,

the cable having a third portion that can be substantially fixed relative to the housing to substantially fix a selected effective diameter for the loop,

wherein the housing comprises a body with a through bore through which the cable extends and through which the cable is slidable and a second bore defining a receptacle that receives the first portion of the cable,

the through bore having a diameter,

the through and second bores each have a central axis, and the central axes are at a substantial angle with respect to each other with the first and third portions of the cable fixed relative to the housing,

wherein with the first portion of the cable in the receptacle, the housing is slidable along the cable between a first position wherein the loop has a minimum effective diameter and a second position wherein the loop has a maximum effective diameter,

the housing capable of being fixed at any location along the length of the cable between the first and second positions,

wherein the cable has a free end defining the first portion of the cable,

the free end of the cable capable of being directed into and through the through bore and from there into the second bore,

the cable having an outer surface with a substantially uniform diameter that is slightly less than the diameter of the through bore; and

b) an object to be secured and having a portion with a reduced circumference that is surrounded by the loop defined by the cable so that the loop is confined at the portion of the object.

2. The combination according to claim 1 wherein the housing has a single piece in which the through bore and receptacle are defined.

3. The combination according to claim 1 wherein the free end of the cable comprises a fitting defining a shoulder and a first locking element is directed into the housing with the cable free end in the receptacle, the first locking element abutting to the shoulder to block the fitting in the receptacle.

4. The combination according to claim 3 further comprising a second locking element that is directed into the housing and abuts the shoulder to block the fitting in the receptacle.

5. The combination according to claim 1 wherein the housing is capable of being fixed at the plurality of different locations along the length of the cable by a securing element.

6. The combination according to claim 5 wherein the securing element comprises a threaded element that is threadably engaged with the housing.

7. The combination according to claim 6 wherein the threaded element has a free end that is borne directly against the cable to fix the housing at the plurality of different locations along the length of the cable.

8. The combination according to claim 7 wherein the threaded element tapers towards a point at the free end.

9. The combination according to claim 8 wherein the cable comprises a non-metal material that defines an outer surface of the cable and the free end of the threaded element digs into the outer surface to thereby fix the housing at the plurality of different locations along the length of the cable.

10. The combination according to claim 9 wherein the cable has a metal core and the non-metal material surrounds the metal core.

11. The combination according to claim 10 wherein the metal core comprises braided metal filaments.

12. The combination according to claim 10 wherein the metal core comprises a hardened material.

13. The combination according to claim 3 wherein the cable comprises a metal core and the fitting is crimped to the metal core.

14. The combination according to claim 1 wherein the housing is made from a non-metal material.

15. The combination according to claim 3 wherein the first locking element comprises a pin that is press fit into the housing.

16. The combination according to claim 1 wherein the object comprises one of a television and a computer monitor.

17. The combination according to claim 1 further comprising a connecting assembly for securing the second portion of the cable to a support relative to which an object is to be confined.

18. The combination according to claim 1 wherein the central axes are substantially orthogonal to each other.

19. The combination according to claim 1 wherein the cable has a core with a non-metal material surrounding the core, the non-metal material having an exposed surface with a substantially uniform diameter defining the loop and the third portion of the cable.

20. The combination according to claim 19 wherein the core comprises a metal material.

21. The combination according to claim 20 wherein the non-metal material comprises at least one of rubber and plastic.

22. The combination according to claim 19 wherein the free end of the cable comprises a fitting defining a shoulder facing lengthwise of the cable and the fitting can be directed axially into and through the through bore.

23. The combination according to claim 22 wherein the second bore comprises a blind bore and a locking element abuts to the shoulder to block the fitting in the receptacle.

24. The combination according to claim 23 wherein the housing is capable of being fixed along the length of the cable by a securing element that is threadably engaged with the housing.

25. The combination according to claim 24 wherein the securing element has an exposed head with a receptacle for a non-conventional, complementary operating tool that is used to turn the securing element.

26. The combination according to claim 25 wherein the non-metal material comprises at least one of rubber and plastic and the securing element digs into the non-metal material with the housing fixed along the cable through the securing element.

27. The combination according to claim 26 wherein the securing element has an axis about which the securing element is turned that is substantially parallel to the central axis of the second bore.
