Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-sounding anti-theft tag which is attached to an object such as clothing and footwear and emits an alarm by itself to prevent the object from being stolen, and a wire used for the tag.

[0002]

2. Description of the Related Art In order to prevent theft of a product displayed at a store, an antitheft tag which is activated when a predetermined antitheft signal is received is attached to the product, and the theft is provided near the exit of the store. There is an anti-theft system provided with a transmitter for transmitting an anti-theft signal. In such an anti-theft system, when a clerk tries to take out the product without the anti-theft tag through the exit through the exit, the anti-theft signal transmitted by the transmitter is received by the anti-theft tag, An alarm provided on the anti-theft tag gives an alarm.

As one of such anti-theft tags, Japanese Patent No. 2955449 discloses a wire type anti-theft tag. FIG. 6 is an explanatory diagram showing a use state of this kind of anti-theft tag. In FIG. 6, reference numeral 94 denotes a wire having a connection portion of a conductive pin-shaped member at both ends of a flexible conductor covered with an insulating material. An annular groove is provided in the vicinity of the distal end of the connection portion. On the one end surface of the box-shaped tag main body, two insertion holes for inserting the connection portion of the wire 94 are opened, and inside the both insertion holes, the two connection portions are locked by engaging with the above-described grooves. Locking mechanism is provided. The wire 94 is inserted through a mounting portion of the object T, such as a button hole of an outerwear and a shirt or a tag provided at a collar of a garment, and a connection portion of the wire 94 is engaged with the insertion hole of the tag body by the groove and the lock mechanism. The anti-theft tag 91 is attached to the target object T by inserting the tag until the tag T matches.

[0006] The tag body shown in FIG. 6 includes an antenna for receiving a signal transmitted from a transmitter, a buzzer, a battery, and the like. The transmitter transmits an anti-theft signal having a strength that can be received by the anti-theft tag 91 to a predetermined area. For example, a gate type transmitter is provided at the entrance to prevent the anti-theft signal. When the object T to which the tag 91 is attached approaches the transmitter and the tag body receives the anti-theft signal transmitted from the transmitter, the tag body operates a buzzer to emit an alarm sound, Prevent theft.

The wire 94 functions as a normally closed contact. When the wire 94 is pulled out of the tag body or the wire 94 is cut in order to remove the anti-theft tag 91 from the object T, the tag body is It detects this and activates the buzzer to emit an alarm sound.

[0006]

However, in the conventional anti-theft tag as described above, a stainless steel stranded wire or the like is used for the flexible conductor in order to secure the strength of the wire 94. Since it is easy to remove only the coating without cutting the flexible conductor, the coating near the two connecting portions of the wire 94 is peeled off using a knife or the like to expose the flexible conductor, and these are separated by another conductor. By connecting and cutting the flexible conductor while maintaining the conduction state, or by passing a cylindrical member between the wire 94 and the tag main body, and repeatedly rotating the cylindrical member or the tag main body, both connections of the wire 94 are made. The area around the connecting part is twisted, and the twisting removes the coating near the two connecting parts and exposes the flexible conductor. Cutting the flexible conductor while maintaining the alarm theft preliminary act of detached anti-theft tags from the object without being emitted there is a problem that there is a possibility that place.

The present invention has been made in view of the above circumstances, and has a structure in which a flexible conductor is wound around a linear member, thereby securing the strength of the wire itself with the linear member. Since the flexible conductor can be more easily cut than in the past, when the wire is stripped, the flexible conductor is cut, and the tag body of the anti-theft tag issues an alarm, as described above. An object of the present invention is to provide an anti-theft tag and a wire capable of preventing the object from being stolen due to such a theft preliminary action.

[0008]

According to a first aspect of the present invention, there is provided a theft prevention tag including a flexible conductive member, and a wire covered with an insulating member, and both ends of which are attached to and detached from the wire. And a tag body that detects the disconnection of the conductive member and issues an alarm, wherein the wire includes a flexible linear member, and the conductive member is It is characterized by being wound around the linear member.

According to a second aspect of the present invention, there is provided a wire provided with a conductive member having flexibility, and a wire covered with an insulating member, comprising a linear member having flexibility. It is characterized by being wound around a linear member.

In the case of the anti-theft tag and the wire according to the present invention, the wire has a structure in which a conductive member is wound around a linear member. The strength of the conductive member is lower than before, the conductive member can be more easily cut than before, and the wire is peeled off or the wire is twisted, etc. In this case, the conductive member is cut, and when the tag is detected by the tag main body, an alarm is issued to prevent the object from being stolen.

[0011]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is an external perspective view showing the configuration of an embodiment of the anti-theft tag according to the present invention.
In the figure, 1 is a box-shaped tag main body, and 2 is a wire.
FIG. 2 is a front view showing the anti-theft tag shown in FIG. 1 with the wire 2 removed from the tag body 1. The wire 2 has two connection portions 21 and 21 at both ends of a wire main body 22 to be described later in which a conductive pin-shaped member is coated with an insulating synthetic resin except for its tip.
Annular grooves 51, 51 are provided on the peripheral surface near the front end of 21, respectively.

Two insertion holes 1 into which both connecting portions 21 and 21 of the wire 2 can be inserted are provided at one end surface of the tag body 1.
A lock mechanism (not shown) for locking the grooves 51, 51 is provided inside the two insertion holes 11, 11, respectively. Then, the wire 2 is passed over the attachment portion of the object to be stolen, and the wire 2
Connecting portions 21 and 21 of the tag body 1
Then, the anti-theft tag can be attached to the object by inserting the grooves 51 and 51 until the lock mechanism is engaged.

The tag body 1 includes an antenna for receiving a signal transmitted from a transmitter, a buzzer, a battery, and the like. The transmitter is configured to transmit a signal of an intensity that can be received by the tag main body 1 into the monitoring area. By providing the transmitter at a gate installed at the entrance of the store,
An object with an anti-theft tag approaches the gate,
When the tag main body 1 receives the signal transmitted from the transmitter, the tag main body 1 activates a buzzer, emits an alarm sound, and prevents the object from being stolen.

Further, the wire 2 functions as a normally closed contact, so that the wire 2 is cut or removed without a regular operation in order to remove the anti-theft tag from the object.
Is extracted from the tag main body 1, the tag main body 1 detects this and activates a buzzer to emit an alarm sound.

FIG. 3 is a side sectional view showing the structure of the wire 2, and FIG. 4 is a front sectional view taken along line IV-IV of FIG. FIG. 5 is a side sectional view showing the structure of the connecting portion 21 of the wire 2. As shown in FIG. 3 and FIG. 4, the wire main body 22 is formed by spirally winding a single conductive wire 4 covered with an insulating coating 41 on a core material 3 made of a bundle of polyester fibers over the entire length. It is further formed to cover an insulating coating 31.

Although the core member 3 of the wire body 22 is made of a bundle of polyester fibers, any material having flexibility and necessary mechanical strength may be made of a material different from the polyester fiber. It goes without saying that 22 core materials 3 may be configured.

Further, as shown in FIG.
It has a pin-like member 5 having one end of a cylinder closed by a sharp head, and the above-described groove 51 is provided in the head.
At the end of the wire main body 22, the core material 3 and the conductive wire 4 extend, and the end of the conductive wire 4 is not covered with the coating 41.
This part is inserted into the inside from the other end opening of the pin-shaped member 5,
By crimping the vicinity of the other end of the pin-shaped member 5,
The conductor 4 and the pin-shaped member 5 are connected and fixed. A cylindrical body 6 made of insulating synthetic resin is externally fitted and fixed to a connection portion between the pin-shaped member 5 and the wire main body 22.

Although the core member 3 and the conductor 4 are connected to the pin member 5 by caulking, the invention is not limited to this. For example, the core member 3 and the conductor 4 are connected to the pin member 5 by soldering. Needless to say, this may be done.

With the above configuration, for example, when the coating 31 and the coating 41 are peeled off by a blade, the conductor 4 is also cut at the same time, so that it is difficult to make the conductor 4 exposed while maintaining the conduction state. The conductor 4 near the parts 21 and 21 is exposed, and this exposed part is connected with another conductor,
Preparing theft by cutting the middle part between both exposed portions of the conductive wire 4 while maintaining the conduction state between the connection portions 21 and 21 can be prevented.

When the wire 2 is repeatedly twisted,
Since the conductive wire 4 is cut before the coating 31 and the coating 41 are peeled off, it is possible to prevent a theft preparatory act by repeatedly twisting the vicinity of both the connection portions 21 and 21 of the wire 2.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the structure shown in the attached drawings.

[0022]

As described in detail above, in the case of the anti-theft tag and the wire according to the present invention, the wire is formed by winding a conductive member around a linear member so that the wire itself can be formed by the linear member. In order to ensure the strength of the conductive member, the strength of the conductive member is reduced as compared with the conventional one, and the conductive member can be more easily cut than before, and the wire coating is peeled off or the wire is twisted. If any such act is performed,
The present invention has an excellent effect such that an alarm can be issued by detecting the conductive member being cut and detected by the tag main body, thereby preventing the object from being stolen.
