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.
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
.
