Abstract

Embodiments of the present invention are directed to recoilers, merchandise security systems, and methods for displaying and protecting an article of merchandise from theft. In one example, the merchandise security system includes a sensor configured to be secured to the article of merchandise and a base for removably supporting the sensor and the item of merchandise thereon. The system also includes a recoiler operably coupled to the sensor. The recoiler includes a rotatable member defining a helical recess. The system further includes a cable configured to connect to the sensor and to be unwound from and wound on the rotatable member as the cable is extended and retracted. The cable is configured to be extended from the recoiler in response to the sensor being lifted off of the base, and the cable is configured to be retracted into the recoiler in response to the sensor being moved to a seated position on the base. The helical recess is configured to at least partially receive the cable therein as the cable is wound on the rotatable member.

First claim

That which is claimed is:

1. A merchandise security system for displaying and protecting an article of merchandise from theft, comprising:
a sensor configured to be secured to the article of merchandise;
a base for removably supporting the sensor and the article of merchandise thereon, wherein each of the base and the sensor comprises one or more electrical contacts that are configured to contact one another when the sensor is seated on the base for transferring electrical power for charging the article of merchandise;
a lock mechanism configured to lock the sensor to the base in a locked position when the sensor is seated on the base to thereby prevent the sensor from being lifted off of the base and to be unlocked to allow removal of the sensor from the base in an unlocked position;
a recoiler operably coupled to the sensor, the recoiler comprising a rotatable member defining a helical recess; and
a cable configured to connect to the sensor and to be unwound from and wound on the rotatable member as the cable is extended and retracted,
wherein the cable is configured to be extended from the base in response to the sensor being lifted off of the base, and wherein the cable is configured to be retracted into the base in response to the sensor being moved to a seated position on the base, and
wherein the helical recess is configured to at least partially receive the cable therein as the cable is wound on the rotatable member.

2. The merchandise security system of claim 1 , wherein an outer surface of the rotatable member defines the helical recess.

3. The merchandise security system of claim 2 , wherein the helical recess has a pitch of less than about 5 mm.

4. The merchandise security system of claim 1 , further comprising a spring secured to one end of the rotatable member.

5. The merchandise security system of claim 4 , further comprising a slip ring secured at an opposite end of the rotatable member.

6. The merchandise security system of claim 1 , further comprising a slip ring coupled to the rotatable member and electrically connected to the cable.

7. The merchandise security system of claim 6 , wherein the cable comprises a plurality of electrical conductors that are electrically connected to the slip ring.

8. The merchandise security system of claim 1 , wherein the rotatable member is configured to rotate about an axis as the cable is wound on and unwound from the rotatable member.

9. The merchandise security system of claim 1 , wherein the cable is configured to be wound about the rotatable member such that the cable overlaps itself on the rotatable member.

10. The merchandise security system of claim 9 , wherein the cable is configured to be wound about the rotatable member and within the helical recess to define a first layer of cable, and wherein the cable is configured to be wound about the first layer of cable to define a second layer of cable.

11. The merchandise security system of claim 10 , wherein the cable is configured to be wound in a first helical direction to define the first layer of cable and to be wound in a second helical direction to define the second layer of cable.

12. The merchandise security system of claim 11 , wherein the first and second helical directions are opposite to one another.

13. The merchandise security system of claim 1 , wherein the rotatable member comprises a spool.

14. The merchandise security system of claim 1 , wherein the base is configured to house the recoiler therein.

15. The merchandise security system of claim 1 , further comprising an auxiliary port disposed within the base and configured to operably connect to an auxiliary device of the article of merchandise.

16. The merchandise security system of claim 15 , wherein a sense loop is defined in the cable and the auxiliary port for detecting removal of the auxiliary device from the base.

17. The merchandise security system of claim 16 , wherein the base is configured to transfer power to the article of merchandise and the auxiliary device.

18. The merchandise security system of claim 1 , wherein the lock mechanism is configured to be moved between the locked position and the unlocked position with a fastener.

19. The merchandise security system of claim 1 , wherein each of the base and the sensor comprises a plurality of electrical contacts for facilitating contact charging of the article of merchandise when the sensor is seated on the base.

20. The merchandise security system of claim 1 , wherein the lock mechanism is configured to lock the sensor to the base to prevent the cable from being unwound from and wound on the rotatable member.

21. The merchandise security system of claim 1 , wherein the lock mechanism is configured to rotate between the locked position and the unlocked position.

22. The merchandise security system of claim 1 , wherein the sensor and/or the base comprises an alarm for generating an audible and/or a visible alarm, and wherein the base is configured to be disarmed with a wireless key.

23. A method for displaying and protecting an article of merchandise from theft, comprising:
securing a sensor to the article of merchandise, a recoiler operably coupled to the sensor and comprising a rotatable member defining a helical recess;
attaching a base to a support surface for removably supporting the sensor and the article of merchandise thereon;
connecting a cable to the sensor;
positioning the sensor on the base, wherein each of the base and the sensor comprises one or more electrical contacts that are configured to contact one another when the sensor is positioned on the base for transferring electrical power for charging the article of merchandise; and
selectively locking a lock mechanism for locking the sensor to the base in a locked position when the sensor is seated on the base to thereby prevent the sensor from being lifted off of the base and unlocking the lock mechanism to allow removal of the sensor from the base in an unlocked position,
wherein the cable is configured to be extended from the base in response to the sensor being lifted off of the base when the lock mechanism is in the unlocked position, wherein the cable is configured to be retracted into the base in response to the sensor being moved to a seated position on the base, and wherein the helical recess is configured to at least partially receive the cable therein as the cable is wound on the rotatable member.

24. The method of claim 23 , further comprising lifting the sensor and the article of merchandise from the base when the lock mechanism is in the unlocked position.

25. The method of claim 24 , further comprising placing the sensor on the base such that the cable winds about the rotatable member and overlaps itself on the rotatable member.

26. The method of claim 25 , wherein placing comprises placing the sensor on the base such that the cable winds about the rotatable member and within the helical recess to define a first layer of cable and such that the cable winds about the first layer of cable to define a second layer of cable.

27. The method of claim 26 , wherein placing comprises placing the sensor on the base such that the cable winds in a first helical direction to define the first layer of cable and to wind in a second helical direction to define the second layer of cable.

28. The method of claim 27 , wherein the first and second helical direct
