Description




BACKGROUND OF THE INVENTION




1. Technical Field




The present invention generally relates to theft deterrent devices for retail establishments and, more particularly, to an EAS tag-carrying device that may be secured to an item of merchandise. Specifically, the present invention relates to a theft deterrent device having a cable that is used to connect the device to an item of merchandise; the cable having a small head that allows it to be threaded through small openings on an item of merchandise while also being selectively connected to a plug that includes one of the portions of the lock mechanism.




2. Background Information




Various retail establishments use theft deterrent systems to discourage shoplifting. A common theft deterrent system uses electronic article surveillance (EAS) tags attached to items of merchandise. The EAS tags are configured to activate an alarm that is positioned at the exit of the establishment.




Securing the EAS tags to merchandise is a problem faced by most retail establishments. The tags must be connected in a secure manner that prevents unauthorized removal while not damaging the items of merchandise. The tags must also be readily removable by authorized personnel so that the tags do not unduly delay checkout.




The prior art is replete with EAS tag carriers designed to secure EAS tags to merchandise. Various types are known in the art such as frames that extend around items, pins that pierce items, and cables that wrap around items. The present invention relates to the types of devices that use cables to wrap around a portion of the merchandise. A problem with these types of devices is that the leading end of the cable is often too large to fit through the openings on the merchandise where the retail establishment wishes to secure the device. Another problem is that the devices must be discarded if the cable portion of the device is broken by the shoplifter. A further problem is that the devices are not always easy to unlock. The invention described in this application addresses these issues.




BRIEF SUMMARY OF THE INVENTION




The invention provides a theft deterrent device that includes a base, a plug, and a cable that is selectively connected to the base and the plug. The plug may be locked to the base to form a closed loop that may be used to hold merchandise. In situations where the plug cannot be threaded through the merchandise, the cable assembly may be disconnected from the plug to provide a smaller cross-section so that it may be threaded through the merchandise. The cable assembly is then reconnected to the plug so that the loop may be locked. The cable assembly is also replaceable so that the user does not have to discard the entire device if the cable is cut.

DETAILED DESCRIPTION OF THE INVENTION




The theft deterrent device of the present invention is indicated generally by the numeral


10


in the accompanying drawings. Device


10


is configured to be securely attached to an item of merchandise


12


(such as the shoe shown in the exemplary embodiment of

FIG. 1

) to deter a shoplifter from steeling merchandise


12


. Device


10


may be used with an EAS tag


14


as shown in FIG.


10


. Device


10


may also be used without tag


14


simply to provide a visual deterrent to shoplifting.




Device


10


generally includes a base


20


, a cable assembly


22


, and a plug


24


. Cable assembly


22


is configured to be selectively attachable to both base


20


and plug


24


. In the context of this application, the word “selectively” is defined as meaning that something may be repeatedly made and unmade. The phrase “selectively attachable” or “selectively connectable” is understood to be a connection that can be repeatedly made and unmade. As such, cable


22


is selectively attachable to base


20


so that the user may disconnect cable assembly


22


from base


20


as needed and then may reconnect cable assembly


22


with base


20


when necessary. This distinguishes prior art references wherein cables are permanently attached with welds, press fits, and other similar connections that prevent repeated removal and reattachment.




In general, device


10


is connected to item


12


by threading cable assembly


22


through an opening


30


defined by item


12


. In some situations, opening


30


is rather small such as the eyelet on the shoe depicted in FIG.


1


. In these situations, plug


24


cannot fit through opening


30


and device


10


would not be able to be used with item


12


unless it could be connected to another portion of item


12


. In accordance with one of the objects of the present invention, plug


24


may be separated from cable assembly


22


so that cable assembly


22


may be threaded through opening


30


. Plug


24


is then locked to base


20


to securely connect device


10


to item


12


. Tag


14


is thus secured to item


12


.




Base


20


generally includes a body


32


and a first portion


24


of a lock mechanism


36


. Body


32


may define a recess or a closed chamber


38


configured to hold tag


14


. The type of tag


14


may define the size and shape of chamber


38


. Body


32


also defines a port


40


configured to selectively receive plug


24


and a portion of cable assembly


22


. First portion


34


of lock mechanism


36


is carried by body


32


such that it is exposed to port


40


. In the exemplary embodiment, first portion


34


is a resilient lock finger that moves between locking (

FIG. 14

) and unlocking (

FIG. 15

) positions. In the exemplary embodiment, the lock finger is fabricated from a magnetically attractable material (such as spring steel) such that the finger may be moved from the locking position to the unlocking position with a magnet


42


as shown in FIG.


15


. The finger automatically moves back to the locking position because of its resilient nature. The finger may project from a frame


44


that is held by body


32


in a secure manner such as being sandwiched between opposed walls (shown in FIG.


12


). Frame


44


may also be snap-fit into body


32


if desired.




The second portion


46


of lock mechanism


36


is formed on plug


24


and includes a ledge that cooperates with the lock finger to lock plug


24


to body


20


. In another embodiment of the invention, the positions of first and second lock members


34


and


46


may be switched so that the lock finger is carried by plug


34


and the ledge is defined by body


32


.




Body


32


includes a plug support wall


50


that supports the bottom of plug


24


when plug


24


is disposed in port


40


. Support wall


50


includes forward, intermediate, and rear portions. As shown in

FIG. 12

, the forward portion of wall


50


is split by a channel


52


that allows a portion of cable assembly


22


to be received between the two split portions of wall


50


. An intermediate portion of wall


50


defines a first recess


50


that is configured to selectively receive a first barrel


62


connected to a first end of cable


61


. Wall


50


may include bosses


64


that function as dual ramps to allow barrel


62


to be snapped into and out of recess


60


. Wall


50


may also define an access opening


66


that allows the user to push barrel


62


out of recess


60


when desired.




Barrel


62


may thus be inserted into port


40


and pressed down into recess


60


to selectively secure cable assembly


22


to base


20


. The user may disconnect cable assembly


22


from base


20


by inserting a suitable pusher into access opening


66


to push barrel


62


back through bosses


64


. Bosses


64


and the walls of body


32


are suitably flexible and resilient to allow for repeated installation and removal of barrel


62


.





FIG. 12

also depicts stopping wall


68


that prevents barrel


62


from being out of channel


52


. Wall


50


also includes an angled portion


70


that prevents plug


24


from catching on wall


50


when it is inserted into base


20


.




Body


32


also includes a top wall


72


that defines a portion of port


40


. Wall


72


is raised from the wall that holds portion


34


to form a step


74


. Step


74


may be used to properly position a key


76


as shown in

FIGS. 15 and 16

so that magnet


42


is properly aligned with lock portion


34


. Key


76


may define its own step


78


to help position device


10


.




Turning now to plug


24


that is selectively received in base


20


, we find that plug


24


has a body


80


having a forward portion and a rear portion. The rear portion of body


80


defines a recess


82


configured to selectively receive a second barrel


84


that is secured to the second end of cable


61


. Bosses


86


similar to those described above are provided on body


80


where they projected out into recess


82


to selectively hold barrel


84


. Body


80


also defines an access opening


88


that allows the user to push barrel


84


out of body


80


.




The rear wall


90


of body


80


defines a slot


92


that receives cable


61


when barrel


84


is snapped into recess


82


. Rear wall


90


prevents barrel


84


from being pulled out of plug


24


.




The forward portion of body


80


defines the second portion of lock mechanism


36


. Second portion


46


of lock mechanism


36


includes a ledge as described above and the ledge is defined by the forward portion of body


80


. Ledge


46


is engaged by lock finger


34


when lock mechanism


36


is in the locked position. Forward portion of body


80


also defines sidewalls


96


that are disposed on the sides of lock fingers


34


when lock mechanism


36


is in the locked position. Walls


96


thus provide lateral support to finger


34


when lock mechanism


36


is locked.




Device


10


may be used by snapping barrel


62


into base


20


so that cable assembly


22


is secure to base


20


. The user may then loop barrel


84


through opening


30


. Barrel


84


is then snapped into plug


24


. Plug


24


is then inserted into base


20


until lock mechanism


36


moves to the locked position. In this position, barrels


82


and


84


are trapped in place and cannot be removed without destroying a portion of device


10


. The device may also be used without disconnecting barrel


84


from plug


24


when opening


30


is large enough to accept plug


24


. Device


10


thus provides a adaptable theft deterrent device that may be used with different items of merchandise


12


.
