Abstract

A merchandise security system for an electronic item of merchandise is provided. In one example, the merchandise security system includes a continuous alarming power cord comprising at least one electrical conductor. The alarming power cord has a first end adapted to be electrically connected to the electronic item of merchandise and a second end. The merchandise security system also includes a reel for receiving the second end of the alarming power cord and adapted for storing at least a portion of the alarming power cord thereon. In addition, the merchandise security system includes monitoring circuitry in electrical communication with the alarming power cord and configured to detect an interruption in an electrical signal provided to the alarming power cord.

First claim

That which is claimed is:

1. A merchandise security system for an electronic item of merchandise comprising:
a cord configured to be coupled to the electronic item of merchandise;
a reel configured to store at least a portion of the cord thereon, the reel comprising at least one electrical coupling on an outer surface thereof; and
a housing defining an interior for receiving the reel therein, the reel configured to be removably inserted within the housing, the housing comprising at least one electrical coupling configured to engage with and electrically connect to the at least one electrical coupling of the reel when the reel is received within the housing.

2. The merchandise security system of claim 1 , wherein each of the reel and the housing comprises a plurality of electrical couplings.

3. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the reel comprises an electrical trace.

4. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the housing comprises an electrical terminal.

5. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the housing is electrically connected to a printed circuit board disposed within the interior of the housing.

6. The merchandise security system of claim 1 , wherein the cord comprises at least one electrical conductor configured to electrically couple to the at least one electrical coupling of the reel.

7. The merchandise security system of claim 6 , wherein the at least one electrical coupling of the reel and the housing are configured to electrically couple with one another for providing electrical power through the cord to the electronic item of merchandise.

8. The merchandise security system of claim 1 , wherein the cord is configured to be electrically connected to the electronic item of merchandise.

9. The merchandise security system of claim 1 , wherein the housing is a display stand configured to removably secure the electronic item of merchandise thereon.

10. The merchandise security system of claim 1 , wherein the housing further comprises means for retracting the cord onto the reel.

11. The merchandise security system of claim 10 , wherein the means for retracting comprises a torsion spring.

12. The merchandise security system of claim 1 , wherein the reel is rotatable for dispensing and collecting a predetermined portion of the cord.

13. The merchandise security system of claim 1 , further comprising a strain relief block configured to be attached to the electronic item of merchandise, wherein a portion of the cord is configured to be routed through the strain relief block.

14. The merchandise security system of claim 1 , wherein the cord comprises a continuous cord extending between the reel and the electronic item of merchandise.

15. The merchandise security system of claim 1 , further comprising a connector coupled to the cord and adapted to engage a power input port of the electronic item of merchandise.

16. The merchandise security system of claim 1 , further comprising monitoring electronics configured to detect an interruption in a signal provided to the cord.

17. The merchandise security system of claim 1 , wherein the housing comprises a barrier configured to cover an opening to the interior of the housing for containing the reel therein and to be removed from the opening for inserting and removing the reel though the opening.

18. The merchandise security system of claim 17 , wherein the barrier comprises a door.

19. A method for securing an electronic item of merchandise from theft, the method comprising:
coupling a cord to the electronic item of merchandise, wherein the cord is coupled to a reel for storing at least a portion of the cord thereon; and
inserting a reel within an interior of a housing such that at least one electrical coupling of the housing engages with and electrically connects to at least one electrical coupling on an outer surface of the reel; and
covering the interior of the housing for retaining the reel therein.

20. The method of claim 19 , further comprising accessing the interior of the housing for removing the reel from the housing.

21. The merchandise security system of claim 1 , wherein the housing defines a hollow interior having an interior surface, and wherein the at least one electrical coupling of the housing is disposed on the interior surface.

22. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the housing is disposed on an interior surface of the interior of the housing.

23. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the housing is coupled to an interior surface of the interior of the housing.

24. The merchandise security system of claim 5 , further comprising a power cable electrically coupled to the printed circuit board for providing electrical power to the item of merchandise.

25. The merchandise security system of claim 24 , wherein the power cable is configured to connect to a power source or power outlet.

26. The merchandise security system of claim 24 , wherein the cord is not in direct wire-to-wire electrical communication with the power cable.

27. The merchandise security system of claim 24 , further comprising monitoring electronics configured to detect electrically decoupling the power cable from the cord at the at least one electrical coupling of the reel and the at least one electrical coupling of the housing.

28. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the reel is circular in shape.

29. The merchandise security system of claim 1 , wherein the housing further comprises a spring for retracting the cord onto the reel.

30. The merchandise security system of claim 16 , wherein the monitoring electronics is configured to detect decoupling of the at least one electrical coupling of the reel from the at least one electrical coupling of the housing.

31. The merchandise security system of claim 16 , wherein the monitoring electronics is configured to activate an audible and/or a visible alarm in response to the interruption in the signal provided to the cord.

32. The merchandise security system of claim 30 , wherein the monitoring electronics is configured to activate an audible and/or a visible alarm in response to decoupling of the at least one electrical coupling of the reel from the at least one electrical coupling of the housing.

33. The merchandise security system of claim 1 , wherein the housing comprises a barrier configured to cover an opening to the interior of the housing for containing the reel therein.

34. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the housing comprises an electrical terminal coupled to an interior surface of the interior of the housing.

35. The merchandise security system of claim 1 , wherein the at least one electrical coupling of the housing comprises an electrical terminal extending between an interior surface of the interior of the housing and the at least one electrical coupling of the reel when the electrical terminal is engaged with and electrically connected to the at least
