Description

  The present invention relates to a binding band and a safety device.

A binding band is widely used as a means for preventing articles including packaging from being separated or opened or opened.
There are various types of such binding bands. In addition to the so-called temporary fixing type that temporarily binds the power cord and the like, there is a non-removable type in which the state once bound is fixed.
In the latter, a band-shaped band (strap) is integrally formed on a synthetic resin head having a through hole, and a serrated protrusion called serration that is locked by a claw in the head is arranged on the band. Since the serrations are combined with the claws by winding the band around the article and pulling it through the through hole of the head from the tip, it is not possible to return the band to the loose side from this state. There are advantages to being

  However, even in this state, if the band is cut using an instrument such as a knife, scissors, or nipper, the effect of tightening and fixing will be lost, and the goods that have been fixed with the binding band will be stolen. There was a problem that could not be prevented. In order to prevent this situation, visual observation must be frequently performed, and there has been a problem that even if it is performed, the effectiveness is poor.

  The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to automatically detect the cutting of the band and to steal, open, and open the article that has been fastened and fixed. To provide a binding band that can be prevented and a safety device using the same.

  In order to achieve the above object, the present invention provides a binding band made of a synthetic resin having a band-shaped band portion and a lock portion that allows the band portion to be inserted and locked so that the band portion cannot be loosened and returned to the loose side. It is characterized in that an electrical wiring for detecting disconnection is internally installed.

  In addition, the present invention provides a synthetic resin binding having a band-shaped band portion provided with an electrical wiring for detecting cutting in the longitudinal direction and a lock portion that is inserted and locked to prevent the band portion from being loosened. A normal circuit part that outputs a detection electric signal through the band and the electric wiring of the binding band, and an illegal signal output that outputs an alarm signal when the electric wiring of the binding band is cut and the detection electric signal is cut off It is characterized by comprising a disconnection detector having a circuit part and a microcomputer for controlling them.

  According to the present invention, since the binding band has electrical wiring for detecting disconnection, it is automatically known that the band has been disconnected by detecting the interruption of the electrical signal by passing the electrical signal through the electrical wiring. In addition, it is possible to monitor and prevent theft, opening, opening, etc. of an article that has been fastened and fixed at a remote location.

Preferably, the tip of the band portion is inserted into the lock portion to form an annular shape, and the electric wiring from the tip of the band portion is connected to the connector.
According to this, it is possible to perform tightening simply by inserting the article into the annular space and pulling the band portion, and since the connector is provided in advance, there is an effect that electrical connection can be easily made to the safety device.

  The configuration of the electrical wiring is arbitrary. In addition to embedding the conductive strips in the band, the band itself may be molded so that the conductive resin is positioned in parallel on both sides of the non-conductive resin, or non-conductive Wiring may be applied to the surface of the conductive resin by a printing method or a painting method.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a binding band according to the present invention in use, wherein 1 is a binding band and 2 is an article to be fastened and fixed by the binding band 1. In this example, an electronic device represented by a control ROM of a gaming machine such as a pachinko machine or a throttle machine is loaded and sealed. Such articles are strictly required to be opened and stolen to prevent fraud.

  Reference numeral 3 denotes an electric wire for cutting detection provided along the longitudinal direction of the binding band 1, and an end portion thereof is led out from the binding band 1 and connected to the connector 4. Reference numeral 5 denotes a cutting detector, which is connected to the connector 4 on the binding band 1 side by a connector 6. Reference numeral 7 denotes an appropriate alarm device such as a lamp or a buzzer electrically connected to the disconnection detector 5.

As shown in FIG. 1, the binding band 1 has a band portion 1a having a flat strip shape made of synthetic resin and a lock portion 1b at one end thereof.
A fine serration 10 having a sawtooth shape is formed in the band portion 1a, and an insertion hole 11 through which the band portion 1a is inserted from the tip is formed in the lock portion 1b. A claw 12 that engages the serration 10 is provided. The claw 12 allows the band portion 1a to move in the insertion direction. However, when a force in the reverse direction is applied, the claw 12 is engaged with the vertical surface of the saw blade so that the locked state is not released.

Although this structure is not different from the conventional binding band, in the present invention, the conductive strips are arranged as the electric wiring 3 in parallel with the longitudinal direction of the band portion 1a.
In this example, the conductive strip is made of a wire or foil, the two strips extend in parallel, make a U-turn around the lock portion 1b, extend to the front end side of the band portion, and the end portions 30 and 30 protrude outside. It is embedded in the resin layer.

  The embedding may be performed by insert molding with a conductive strip placed in the mold during resin molding as shown in FIG. 3 (a), or the band portion 1a may be thickened as shown in FIG. 3 (b). It may be divided into two in the vertical direction and joined by sandwiching a conductive strip between the first part 100 and the second part 101. Alternatively, a planar long U-shaped hole as a whole may be formed in the middle of the resin in the thickness direction, and the molten conductive resin may be poured into the hole to be solidified.

The present invention is not limited to the embedded format. For example, as shown in FIG. 4, conductive resin layers 3 ′ and 3 ′ may be integrally formed on both sides with the non-conductive resin layer 1 ′ interposed therebetween.
Alternatively, as shown in FIG. 5, a conductive strip having a film shape on the surface of the band portion 1a may be applied by a printing method or a coating method. The conductive strip may be made of a material used for printed wiring or a conductive resin. The format of FIG. 5 is sufficient in post-processing, and there is an advantage that the cost can be reduced because it is not necessary to make a special mold. In FIG. 5, although the shallow groove | channel according to the width | variety of a conductive strip is formed in the resin main body, it is not limited to this.
In the case of FIG. 4 and FIG. 5, the external wiring layer for protecting the electric wiring portion or the surface including the electric wiring portion so that the electric wiring 3 does not contact and cause a short circuit even when the article is made of metal. 102 may be covered.

The binding band of the present invention is not limited to the case where the binding band 1 and the connector 4 are separated as shown in FIG. 2, and the band portion 1a is wrapped around the article 2 and connected to the lock portion 1b. .
That is, it is good also as a form which has the connector 4 beforehand like FIG. This may be achieved by connecting the connector 4 to the electrical wiring 3 in a state where the end of the band portion 1a is inserted into the lock portion 1b to form a ring.

In some cases, the electrical wiring 3 may make a U-turn in front of the lock portion 1b without going through the lock portion 1b. Further, the tip of the band portion 1 a may be divided into two forks while including the conductive strip 3.
The target article 2 to be fixed in the present invention is not limited, and includes expensive devices such as a mobile phone and a personal computer, and can also be used as a means for holding this and connecting it to an exhibition place.

FIG. 7 shows a circuit example of a safety device using the binding band 1 according to the present invention. The cutting detector 5 outputs a detection electric signal to the substrate 50 with the microcomputer 8 and the detection electric signal is inputted through the binding band. A normal circuit unit 9a, an illegal signal output circuit unit 9b for outputting an alarm signal when the binding band 1 is cut and the detection electric signal is cut off, and a power supply (not shown).
The normal circuit unit 9a includes a photocoupler 90, and the illegal signal output circuit unit 9b includes a photoMOS 91 as an element.

The operation of the present invention will be described. In the embodiment of FIG. 1, the band portion 1a is wound around the article 2, the tip portion is passed through the insertion hole 11 of the lock portion 1b, and the band portion 1a is pulled in this state. As a result, the serration 10 is engaged with the claw 12, and a tight binding state that does not allow return is achieved. Since the tip 30 of the electric wiring 3 protrudes from the band portion 1a, the connector 4 is connected thereto.
In the embodiment of FIG. 6, since the band portion 1a is passed through the insertion hole 11 of the lock portion 1b and is in an annular shape in advance, the article 2 may be disposed in the annular space and the distal end side of the band portion 1a may be pulled. Since the connector 4 is already connected, the connector connection work as in the first aspect is not required.

  In any case, the connector 4 is connected to the connector 6 of the disconnection detector 5. In this state, an electric signal is output from the microcomputer 8 as a detection pulse. The electrical signals reach the connectors 4-2 and 6-2 from the connectors 6-1 and 4-1 via the electrical wiring 3 of the band portion 1a of the binding band 1. This electric signal is converted by the photocoupler 90 and input to the detection signal input unit of the microcomputer 8, and the microcomputer 8 determines that the flow of the electric signal is normal.

From this state, when the connector 4 is removed or even a part of the band portion 1a is disconnected from the connector 4, an electrical signal serving as a detection signal of the microcomputer 8 is cut off. The microcomputer 8 determines that this is abnormal, the illegal signal output circuit unit 9b is activated, an electric signal is output from the illegal output unit, and is converted into a signal by the photo MOS 91 and then output to the alarm device 7.
Thereby, it is possible to know the occurrence of the theft, opening, opening, etc. of the article fixed by the binding band 1 even from a remote place without monitoring by one person, and the crime prevention effect can be improved.
