Abstract

An anti-sweeping hook includes a display hook, a helical coil, and a rotating handle. The display hook may be substantially straight and has a first end and a second end opposite the first end. The helical coil is disposed about the display hook and extends along a lengthwise portion of the display hook. The helical coil has a first coil end proximate the first end of the display hook. Rotation of the helical coil in a first direction loads the retail merchandise onto the display hook. Rotation of the helical coil in a second direction opposite the first direction removes the retail merchandise from the display hook. The rotating handle is configured to determine a change in an amount of stored inventory based on the amount and direction of rotation of the rotating handle.

Claims (43)

1. An anti-sweeping hook comprising:

a display hook for storing retail merchandise, the display hook being substantially straight and having a first end and a second end opposite the first end;

a helical coil disposed about the display hook and extending along a lengthwise portion of the display hook, the helical coil having a first coil end proximate the first end of the display hook, wherein rotation of the helical coil in a first direction of the helical coil loads the retail merchandise onto the display hook, and rotation of the helical coil in a second direction of the helical coil opposite the first direction of the helical coil removes the retail merchandise from the display hook;

a rotating handle attached to the first coil end and adjacent to the first end of the display hook, wherein the rotating handle is configured to determine a change in an amount of stored inventory based on the amount and direction of rotation of the rotating handle;

wherein the rotating handle includes a first circuit and a second circuit; and

a state change of the first circuit without a state change in the second circuit indicates rotation of the rotating handle in a first direction and a state change of both the first and second circuits indicates rotation of the rotating handle in a second direction, opposite the first direction.

2. The anti-sweeping hook of claim 1 , wherein:

the rotating handle includes a rotor and stator each disposed within a main housing of the rotating handle, the rotor rotates relative to the stator with the main housing when the main housing rotates in a first direction of the main housing and the rotor remains fixed relative to the stator when the main housing is rotated in a second direction of the main housing;

the first circuit includes a first contact carried by the stator and a pair of contacts carried by the main housing;

the second circuit includes a second contact carried by the rotor and a pair of contacts carried by the main housing;

rotating the main housing in the first direction of the main housing causes the first contact to selectively connect and disconnect the pair of contacts of the first circuit carried by the main housing but does not cause the second contact to selectively connect and disconnect the pair of contacts of the second circuit carried by the main housing; and

rotating the main housing in the second direction of the main housing causes the first contact to selectively connect and disconnect the pair of contacts of the first circuit carried by the main housing and does cause the second contact to selectively connect and disconnect the pair of contacts of the second circuit carried by the main housing.

3. The anti-sweeping hook of claim 2 , wherein the stator is configured to prevent rotation of the rotor and of the second contact in the second direction of the helical coil, and configured to allow rotation of the rotor and of the second contact in the first direction of the helical coil.

4. The anti-sweeping hook of claim 2 , wherein the rotating handle includes a circuit board with circuitry configured to count the electrical connections between the first contact and the pair of contacts carried by the rotating handle of the first circuit and to count the electrical connections between the second contact and the pair of contacts carried by the rotating handle of the second circuit.

5. The anti-sweeping hook of claim 4 , wherein the rotating handle includes a wireless communications module configured to transmit inventory data related to the amount of product stored on the display hook to a local or remotely-located receiving device.

6. The anti-sweeping hook of claim 4 , wherein the circuit board is configured to determine the amount of stored inventory based on a number of electrical connections made by the first and second circuits.

7. The anti-sweeping hook of claim 4 , wherein the circuit board is configured to determine the change in the amount of stored inventory based on a number of electrical connections made by the first and second circuits.

8. The anti-sweeping hook of claim 2 , wherein the stator is fixed relative to the display hook.

9. A method of determining a change in an amount of stored inventory on an anti-sweeping hook comprising:

rotating a rotating handle of the anti-sweeping hook, the anti-sweeping hook including:

a display hook configured for storing retail merchandise, the display hook having a first end and a second end opposite the first end;

a helical coil disposed about the display hook and extending along a lengthwise portion of the display hook, the helical coil having a first coil end proximate the first end of the display hook, wherein rotation of the helical coil in a first direction of the helical coil loads the retail merchandise onto the display hook, and rotation of the helical coil in a second direction of the helical coil opposite the first direction of the helical coil removes the retail merchandise from the display hook, the rotating handle being attached to the first coil end and adjacent to the first end of the display hook;

determining a change in the amount of stored inventory by determining the amount of rotation of the rotating handle and direction of rotation of the rotating handle;

wherein determining the direction of rotation of the rotating handle includes:

determining that the direction of rotation is in a first direction of a main housing when a state change of a first circuit of the rotating handle without sensing a state change of a second circuit is sensed; and

determining that the direction of rotation is in a second direction, opposite the first direction of the main housing, when a state change of both the first and second circuits is sensed.

10. The method of claim 9 , wherein:

the first circuit includes a first contact carried by a stator and a pair of contacts carried by the main housing;

the second circuit includes a second contact carried by a rotor and a pair of contacts carried by the main housing;

rotating the main housing of the rotating handle in a first direction of the main housing rotates the rotor of the rotating handle relative to the stator of the rotating handle, rotation of the main housing in the first direction of the main housing causes the first contact to selectively connect and disconnect the pair of contacts of the first circuit carried by the main housing but does not cause the second contact to selectively connect and disconnect the pair of contacts of the second circuit carried by the main housing;

when rotating the main housing of the rotating handle in a second direction of the main housing, the rotor remains fixed relative to the stator when the main housing is rotated in the second direction of the main housing, and rotation of the main housing in the second direction of the main housing causes the first contact to selectively connect and disconnect the pair of contacts of the first circuit carried by the main housing and does cause the second contact to selectively connect and disconnect the pair of contacts of the second circuit carried by the main housing.

11. The method of claim 10 , comprising:

preventing, with the stator, rotation of the rotor and of the second contact in the second direction of the main housing, and

allowing, with the stator, rotation of the rotor and of the second contact in the first direction of the main housing.

12. The method of claim 10 , further comprising:

counting the electrical connections between the first contact and the pair of contacts carried by the rotating handle of the first circuit, and

counting, via a circuit board, the electrical connections between the second contact and the pair of contacts carried by the rotating handle of the second circuit.

13. The method of claim 12 , wherein the circuit board is configured to determine a change in the amount of stored inventory based on a number of electrical connections made by the first and second circuits.

14. The method of claim 13 , wherein the circuit board is configured to determine an amount of stored inventory based on the change in the amount of stored inventory based on the number of electrical connections made by the first and second circuits.

15. The method of claim 10 , wherein the stator is fixed relative to the display hook.

16. The method of claim 12 , wherein:

counting the electrical connections between the first contact and the pair of contacts carried by the rotating handle of the first circuit is performed by the circuit board, and

counting the electrical connections between the second contact and the pair of contacts carried by the rotating handle of the second circuit is performed by the circuit board.
