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 connected 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; and
a housing defining an interior for receiving the reel therein, 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 the at least one electrical coupling of the reel is located on an outer surface of the reel.

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

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

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

6. The merchandise security system of claim 5 , wherein the electrical terminal is electrically connected to a printed circuit board disposed within the interior of the housing.

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

8. The merchandise security system of claim 7 , 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 cable to the electronic item of merchandise.

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

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

11. The merchandise security system of claim 1 , wherein the housing further comprises means for retracting the cord onto the reel, and wherein the reel and the portion of the cord stored thereon are detachable from the means for retracting.

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

13. The merchandise security system of claim 1 , wherein the housing further comprises a hub configured to engage the reel when the reel is received within the housing.

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

15. 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.

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

17. The merchandise security system of claim 16 , wherein an end of the cord comprises a connector adapted to engage a power input port of the electronic item of merchandise.

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

19. 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.

20. A method for securing an electronic item of merchandise from theft, the method comprising:
connecting a cord to the electronic item of merchandise, wherein the cord is connected to a reel for storing at least a portion of the cord thereon; and
inserting a reel within a housing such that at least one electrical coupling of the housing engages with and electrically connects to at least one electrical coupling of the reel.

21. The merchandise security system of claim 1 , wherein the reel is configured to be removably inserted within the housing.

22. The merchandise security system of claim 19 , wherein the barrier comprises a door.

23. The method of claim 20 , wherein inserting comprises inserting the reel within an interior of the housing.

24. The method of claim 23 , further comprising covering the interior of the housing for retaining the reel therein.

25. The method of claim 24 , further comprising accessing the interior of the housing for removing the reel from the housing.
