Abstract

A theft deterrent device allows a customer to handle an item of merchandise to which the device is connected. The device is configured to protect items of merchandise having first and second pieces each of which are sufficiently valuable to warrant such protection. The device includes a base mountable on a support structure, an audible alarm, first and second connectors which attach respectively to the first and second pieces of the item of merchandise, lanyards for connecting the base to the first and second connectors and a removal sensor for sensing removal of one or both of connectors from the first and second pieces of the item of merchandise so that the alarm is activated when the connector or connectors are removed from the item of merchandise. The lanyards provide electrical communication between the alarm and the connectors, which may include plunger switches which serve as removal sensors.

Claims

1. A theft deterrent device comprising:

a base adapted to mount on a support structure;

an audible alarm;

a first connector movable between attached and removed positions;

wherein the first connector is adapted to attach to a first piece of an item of merchandise in the attached position and be removed therefrom in the removed position;

a second connector movable between attached and removed positions;

wherein the second connector is adapted to attach to a second piece of the item of merchandise in its attached position and be removed therefrom in its removed position;

at least one lanyard for connecting the base to each of the first and second connectors;

wherein the at least one lanyard includes a first lanyard extending between and connected to the base and the first connector; and

a second lanyard extending between and connected to the first connector and the second connector;

at least one removal sensor for sensing movement of at least one of the first and second connectors from its respective attached position to its respective removed position;

wherein the alarm is activated when one of the connectors moves from its respective attached position to its respective removed position.

2. The device of claim 1 wherein the at least one removal sensor is connected to one of the first and second connectors.

3. The device of claim 2 wherein the at least one removal sensor includes a first removal sensor connected to the first connector for sensing movement of the first connector from its attached position to its removed position and a second removal sensor connected to the second connector for sensing movement of the second connector from its attached position to its removed position.

4. The device of claim 1 wherein the removal sensor includes at least one plunger switch which is connected to one of the first and second connectors and has a plunger which is movable between depressed and non-depressed positions associated respectively with the attached and removed positions of the one of the connectors.

5. The device of claim 4 wherein the at least one plunger switch includes first and second plunger switches which are respectively connected to the first and second connectors.

6. The device of claim 4 wherein the at least one plunger switch is in electrical communication with the alarm via the at least one lanyard.

7. The device of claim 1 wherein the alarm is connected to the base.

8. The device of claim 1 wherein each of the first and second connectors is in electrical communication with the alarm via the lanyards.

9. The device of claim 1 wherein the at least one removal sensor includes a first removal sensor connected to the first connector for sensing movement of the first connector from its attached position to its removed position and a second removal sensor connected to the second connector for sensing movement of the second connector from its attached position to its removed position.

10. The device of claim 9 wherein each of the removal sensors includes at least one plunger switch having a plunger which is movable between depressed and non-depressed positions associated respectively with the attached and removed positions of the respective connector.

11. The device of claim 1 wherein the at least one lanyard provides electrical communication between the alarm and the first connector.

12. The device of claim 11 wherein the at least one lanyard provides electrical communication between the alarm and each of the first and second connectors.

13. The device of claim 1 wherein the alarm is activated if the at least one lanyard is severed.

14. The device of claim 1 wherein the alarm is activated if the at least one lanyard is disconnected from the base or connectors.

15. The device of claim 1 wherein the first and second connectors each include an adhesive pad whereby the first and second connectors are adapted to attach respectively to the first and second pieces of the item of merchandise.

16. The device of claim 1 in combination with the item of merchandise;

wherein the first connector in its attached position is attached to the first piece of the item of merchandise; and

wherein the second connector in its attached position is attached to the second piece of the item of merchandise.

17. The combination of claim 16 wherein the first and second pieces of the item of merchandise are removably connected to one another.

18. The combination of claim 17 wherein the at least one lanyard includes a first lanyard extending between and connected to the base and the first connector;

and a second lanyard extending between and connected to the first connector and the second connector; and

wherein the second lanyard has length sufficient to allow the first and second pieces to be removed from one another while connected to the first and second connectors.
