[0001] 1. Technical Field

[0002] The present invention relates generally to theft deterrent devices for retail establishments. More particularly, the invention relates to a security device which attaches to an item of merchandise. Specifically, the invention relates to such a security device which attaches to an item of merchandise which having two pieces each of which are protected by the security device.

[0003] 2. Background Information

[0004] Retail stores have had a difficult time in protecting items of merchandise which the potential customer wishes to visually inspect and handle prior to making the decision to purchase the item. Often, such items of merchandise have been kept in a glass case under lock and key, which does not allow the customer to handle the item without the assistance of store personnel. In addition, while such items may be secured to a foundation or base by a cable or the like, this does not necessarily prevent the theft of the item by the cutting of the cable. Thus, there is a need in the art for security devices which allow for the handling of the item and which will alarm should someone try to steal the item. Certain items of merchandise have two pieces which are removable connected to one another and each of which are sufficiently valuable for the retailer to desire protection against theft of either piece of the merchandise.

[0005] The present invention provides 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 there from 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 there from in its removed position; at least one lanyard for connecting the base to each of the first and second connectors; 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 the at least one connector moves from its respective attached position to its respective removed position.

[0006] The present invention further provides a security 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 there from 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 there from in its removed position; at least one lanyard which provides electrical communication between the alarm and each of the first and second connectors; wherein movement of one of the first and second connectors from its respective attached position to its respective removed position activates the alarm.

[0019] A first embodiment of the security device of the present invention is indicated generally at 10 in FIGS. 1 and 2; a second embodiment is indicated generally at 100 in FIG. 6; and the third embodiment is indicated generally at 200 in FIG. 9. Referring to FIG. 1, device 10 is shown mounted on an item of merchandise 1 in the form of a battery powered drill which has first and second pieces 2 and 3. First piece 2 is more particularly the drill body and second piece 3 is the rechargeable battery which provides power to body 2 in order to operate drill 1. First and second pieces 2 and 3 are removable connected to one another and are sufficiently valuable to make it desirable to protect each piece 2 and 3 from theft. Device 10 is configured to set off an alarm should the theft of either piece 2 and 3 be attempted.

[0020] Device 10 includes an alarming station or member 12 which is securely mounted on a wall or other support structure 4. Alarming member 12 is described in co-pending provisional patent application having Ser. No. 60/644,206, the contents of which are incorporated herein by reference. Item 1 of merchandise is seated on a display surface 5. A lanyard assembly 14 is connected to each of alarm member 12 and item 1 of merchandise.

[0021] With reference to FIGS. 1 and 2, lanyard assembly 14 includes first and second lanyards 16 and 18 and first and second connectors 20 and 22. First lanyard 16 is in the form of an alarming cable which is connected to alarm member 12 via a removable plug 24 and to first connector 20, which is shown attached in FIG. 1 to first piece 2 of item 1 of merchandise. Second lanyard 18 extends between and is connected to first and second connectors 20 and 22. Second connector 22 is shown in FIG. 1 attached to second piece 3 of item 1 of merchandise. In the exemplary embodiment, first and second connectors 20 and 22 are attached to first and second pieces 2 and 3 via an adhesive although other attachment mechanisms may be used. An adhesive connection provides a mechanism for preventing marring of the item of merchandise while allowing the item to be handled easily by the potential customer.

[0022] Referring to FIG. 2, first and second connectors 20 and 22 have respective removal sensors 26 and 28 in the form of plunger switches having respective first and second plungers 30 and 32 which are shown in an extended, non-depressed or removed position associated with being removed from item 1 of merchandise. When either one of plungers 30 and 32 are in the extended or removed position, alarm 12 will emit an audible alarm. However, alternate removal sensors may be utilized in place of plunger switches 26 and 28. Thus, device 10 is configured so that first and second connectors 20 and 22 attach to pieces 2 and 3 of item 1 of merchandise in a reasonably secure manner, but without being locked thereto. Thus, in the exemplary embodiment, there is no locking mechanism for locking device 10 to item 1 of merchandise and thus no key for the removal thereof. Thus, while connectors 20 and 22 may be pried off of item 1 of merchandise with some difficulty, the result is the sounding of the alarm of alarm member 12.

[0023] Referring to FIGS. 2 and 3, first connector 20 includes a housing 34 comprising first and second housing members 36 and 38. First housing member 36 defines an interior chamber 40 and first and second entrance openings 42 and 44 which communicate therewith. Second housing member 38 is in the form of a substantially flat oval-shaped bottom wall which is securely mounted to first housing member 36. Second housing member 38 defines an opening 46 for receiving plunger 30 of switch 26 there through. Interior chamber 40 of first housing member 36 is configured to receive a body 48 of switch 26 with portions of first and second lanyards 16 and 18 extending respectively through first and second entrance openings 42 and 44. Interior chamber 40 is also configured to receive other related structures such as structure 50 which may be for example, a magnet or an electronic article surveillance (EAS) tag. Use of an EAS tag may allow for the sounding of an alarm other than alarm member 12 should alarm member 12 somehow be nonfunctional. First connector 20 further includes a mounting mechanism in the form of an adhesive pad 52 which defines an opening 54 for receiving there through plunger 30 of switch 26. Second connector 22 likewise has a housing 64 and an adhesive pad 66 which defines an opening 68 for receiving there through plunger 32 of switch 28. Second connector 22 is thus adhered to second piece 3 of the item of merchandise via adhesive pads 66. As seen in FIGS. 3 and 4, entrance openings 42 and 44 are disposed adjacent one end of first housing member 36 so that first and second lanyards 16 and 18 extend generally from that end of housing member 36.

[0024] Alarming cable 16 includes four wires 56A, 58A, 60A and 62A. Second alarming cable 18 likewise includes four wires 56B, 58B, 60B and 62B which may or may not be continuous with wires 56A-62A of first cable 16. These wires provide respective electrical communication between plug 24 and each of switches 26 and 28 to form respective electrical circuits which are either open or closed when plungers 30 and 32 are respectively depressed.

[0025] Device 10 is thus configured to sound an alarm of alarm member 12 if a potential thief attempts to steal either piece 2 and 3 of item 1 of merchandise by removing either of first and second connectors 20 and 22 from said pieces 2 and 3. More particularly, when plunger 30 of switch 26 is in a depressed position associated with the attached position of member 20 on first piece 2 of the article of merchandise (FIGS. 1 and 5), alarm member 12 will not sound an alarm. Second switch 28 of second connector 22 is likewise configured. Removal of either of first and second connectors 20 and 22 will respectively allow plunger 30 and 32 to extend and thus either open or close the respective electrical circuit which will cause alarm member 12 to sound an alarm. These circuits may be sense loops which if compromised cause the alarm of alarm member 12 to sound. For example, if plug 24 is removed from alarm member 12 or if one of lanyards 16 and 18 is severed, alarm member 12 will sound the alarm. In addition, as previously noted, should alarm member 12 somehow be nonfunctional, an EAS tag 50 or the like may allow for the sounding of an alarm should a connector 20 or 22 carrying such a tag remain attached to the item as it moves near or through a security gate. These various alarming characteristics and in particular used with a security gate are described in greater detail in co-pending patent application entitled Electronic Security Device and System for Article of Merchandise, filed on or about Dec. 20, 2005, the contents of which are incorporated herein by reference. Said application claims priority from provisional patent application having Ser. No. 60/639,770, filed on Dec. 28, 2004, the contents of which are also incorporated herein by reference.

[0026] With reference to FIGS. 6-8, security device 100 is described. Security device 100 is similar to security device 10 and operates in the same manner except that it has a lanyard assembly 102 which varies from lanyard assembly 14 of device 10. More particularly, lanyard assembly 102 includes first and second lanyards 104 and 106 which are similar to lanyards 16 and 18. In addition, assembly 102 includes a first connector 108 and second connector 22. The primary distinction between lanyard assembly 102 and lanyard assembly 14 is that assembly 102 allows for first and second lanyards 104 and 106 to extend from opposite ends of first connector 108. To that effect, first connector 108 defines an interior chamber 110 and first and second entrance openings 112 and 114 which communicate therewith and are formed on opposite ends of connector 108. First and second entrance openings 112 and 114 respectively receive portions of first and second lanyards 104 and 106 which are in electrical communication with switch 26 mounted within interior chamber 110. One skilled in the art will appreciate that the wiring configuration of lanyards 104 and 106 may vary as required in order to provide the electrical communication which provides the alarming characteristics described with respect to device 10.

[0027] With reference to FIGS. 9-11, security device 200 is described. Device 200 is similar to devices 10 and 100 except that it utilizes a single connector for attaching to an item of merchandise. More particularly, device 200 includes a lanyard assembly 200 which utilizes a single lanyard 104 and a single connector 208. Connector 208 is similar to connectors 20 and 108 except for it defines an interior chamber 210 having a single entrance opening 212 for receiving therein a portion of lanyard 104 to provide electrical communication between switch 26 and plug 24. Security device 200 thus is configured to attach to an item of merchandise at one location instead of the two locations provided by the first and second connectors of devices 10 and 100. However, devices 200 similarly provides the removal sensor in the form of plunger switch 26 which provides for the sounding of alarm member 12 should connector 208 be removed from the item of merchandise.
