DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burglar alarm device for a display, such as a store or a showroom, for preventing the display of a display placed on a display shelf.

[0002]

2. Description of the Related Art In a store or the like, a product sample is displayed on a display shelf so that a customer can directly contact the product. At this time, in order to prevent the exhibit from being stolen, the display shelf and the exhibit are connected by a theft-preventing code. In addition, the tip of the anti-theft cord is attached to the exhibit using an attachment piece equipped with a switch, and the alarm is activated by electrically detecting that the cord has been cut or the attachment piece has been removed. Things have also been done.

In such a burglar alarm using a theft prevention code, there is a problem that as the number of exhibits increases, the number of codes increases, and the appearance and appearance of the code become worse. In order to solve such a problem, a wound-up anti-theft cord is described in Japanese Utility Model Registration No. 3021776.

[0004]

In the burglar alarm system using the above-described anti-theft cord, one end of the cord is fixed to a display shelf, and a mounting piece having a predetermined area is attached to the other end of the cord. The mounting piece is adhered to the exhibit with an adhesive sheet. Generally, the adhesive surface of the mounting piece is flat, but in the case of an exhibit whose outer shape is formed from a curved surface, the adhesion between the adhesive surface of the mounting piece and the surface of the exhibit is low,
The mounting piece cannot be firmly adhered to the exhibit, and when the customer picks up the exhibit and looks at it, when the exhibit is taken out to the limit of the cord, force is applied directly to the mounting piece from the cord, The mounting piece may come off. When the mounting piece is detached, the switch provided on the mounting piece is turned on and the alarm is activated, so that there is a problem that the customer feels unpleasant and cannot reliably manage theft prevention.

Accordingly, an object of the present invention is to prevent a malfunction of the theft alarm device in a theft alarm device using an anti-theft code.

Being energized. The cord 2 is composed of a pair of mutually insulated lead wires for electrical connection, a synthetic resin coating, and the like, and has a length of, for example, 1.5 m. The core wires of the pair of lead wires are each formed of a stranded wire obtained by twisting a stainless wire and a copper wire, and the stainless wire secures the tensile strength. The two core wires on the proximal end side of the lead of the cord 2 are electrically connected to two sliding electrodes (not shown) provided on the side surface of the rotating reel. Inside the case of the winder 1, there are provided two concentric annular electrodes (not shown) slidably in contact with the two sliding electrodes. These two annular electrodes are electrically connected to the center terminal and the outer peripheral terminal of the jack 3 attached to the back of the winder 1. Note that the internal configuration of the winder 1 is not the gist of the present invention, and thus will not be described in detail.

[0010] A switch 4 is attached to the end of the cord 2 pulled out from the winder 1. FIG. 3 is a perspective view of the switch 4 as viewed from the bottom side. A flat mounting surface 5 is formed on the bottom surface of the switch 4, and an actuator 6 of the switch 4 is provided so as to protrude from the mounting surface 5. The switch 4 is set to be turned off when the actuator 6 is in the protruding state. In the initial state, as shown in FIG. 3A, a release paper 8 is attached to the surface of the adhesive sheet 7 attached to the mounting surface 5.
Is affixed.

A relay bracket 9 is mounted near the switch 4 so as to be slidable with respect to the cord 2. On the bottom surface of the relay bracket 9, as shown in FIG.
Similarly to the switch 4, an adhesive sheet (not shown) is attached, and a release paper 10 is attached thereon. The area of the relay bracket 9 is set so that a sufficient adhesive force is obtained.
It is desirable that the area be larger than the bottom area of the switch 4. Also,
The relay bracket 9 is formed of a flexible elastic member such as synthetic rubber so that the display bracket 14 can be in close contact even when the surface of the exhibit 14 is curved.

A stopper 11 made of synthetic resin is attached at a position slightly away from the tip of the cord 2, for example, at a position about 20 cm away. This stopper 11
A strap 12 made of a stainless steel wire coated with nylon is attached in a loop shape, and a Z-shaped notch 13 for locking the strap 12 is formed.

Next, the manner of use of the above-described exhibit burglar alarm device will be described. First, as shown in FIG. 3A, the release paper 8 is peeled off from the bottom surface of the switch 4, and FIG.
As shown in (b), the adhesive surface of the adhesive sheet 7 is exposed. Next, as shown in FIG. 5, the adhesive surface of the switch 4 is pressed against the surface of the exhibit 14 so that the switch 4 is
Paste in. Next, as shown in FIG. 4, the release paper 10 is peeled off from the adhesive sheet on the bottom surface of the relay bracket 9, and the relay bracket 9 is attached to the exhibit 14 in the same manner as the switch 4. At this time, since the relay bracket 9 is slidable with respect to the cord 2, the relay bracket 9 can be attached to an appropriate position according to the size and shape of the exhibit 14. Also, since the relay bracket 9 has flexibility, the display
Even if the surface of the adhesive sheet is curved, the entire surface of the adhesive sheet can be pressed, and the relay bracket 9 can be firmly attached to the exhibit 14.

As shown in FIG. 6, when there is a locking portion 14a through which the strap 12 can be passed through the exhibit 14, the tip of the strap 12 is passed through the locking portion 14a to cut out the stopper 11. 13, the cord 2 and the exhibit 14 can be connected by the strap 12.

FIGS. 7 and 8 are perspective views for explaining the operation of fixing the winder 1 to the display shelf. The case of the winder 1 is provided with a projection 16 having an insertion hole 15 formed therein and a concave groove 18 having an insertion hole 17 formed therein. As shown in FIG. 7A, when the winder 1 is fixed to the vertical portion of the display shelf 23, as shown in FIG.
After the mounting bracket 19 is inserted into the insertion hole 17 along the concave groove 18, the mounting bracket 19 is bent and fixed to a predetermined position on the display shelf 23 as shown in FIG. FIG.
When the take-up device 1 is fixed to the horizontal portion of the display shelf 23 as shown in FIG. 8A, the mounting bracket 19 is attached to the insertion hole 15 formed in the projection 16 as shown in FIG. After the insertion, as shown in FIG. 8C, the mounting bracket 19 is bent and fixed at a predetermined position on the display shelf 23. In addition, the winder 1 can also be fixed to a display shelf using a double-sided adhesive sheet or the like.

One plug 20 of a connection cord 22 having plugs 20 and 21 connected to both ends thereof is inserted into a jack 3 provided on the back surface of the winder 1, and the other plug 21 is connected to a central portion (not shown). It is inserted into the jack of the management device. The central control device is connected from the central control device to the connection code 2
An on / off state when the two sides are viewed is detected, and an alarm is issued when an off state, that is, an open state is detected.

In the state where the display article 14 is displayed on the display shelf, the cord 2 is wound around the winder 1, so that the cord 2 does not become entangled or unsightly. When the customer wants to hold the exhibit 14 in his hand, the cord 2 is pulled out from the inside of the winder 1 by holding the exhibit 14 and pulling it toward the user. The code 2 does not cause any trouble. At this time, tension is applied to the cord 2, but this tension is received by the relay bracket 9 attached to the display article 14 and is not directly applied to the switch 4. Therefore, in a normal use state, the switch 4 does not peel off from the exhibit 14, and no alarm is issued carelessly. Also, if the exhibit 14 is returned to the original position, the code 2
Is wound inside the winder 1.

If the user tries to steal the display 14 by forcibly removing the switch 4 from the display 14, the switch 4 is turned off and an alarm is issued. Also, when the cord 2 is cut and the exhibit 14 is to be stolen, an alarm is issued because the circuit is open.

[0019]

According to the present invention, a relay bracket for supporting a cord is provided near a switch attached to an exhibit and attached to the exhibit, so that tension applied to the cord is not directly applied to the switch, and the switch can be used. It will not be accidentally disconnected and an alarm will be issued by mistake.
