JP3239858U - Mooring anti-theft device with improved curl cord entanglement - Google Patents

Abstract

[Problem] It is possible to prevent deterioration of the elasticity of the curled cord due to twisting and tangling of the curled cord, to enable display that does not affect the aesthetic appearance of the product display, and to accurately count the number of times a customer touches the displayed product. To provide a secure mooring type anti-theft device. [Solution] The mooring type anti-theft device prevents twisting and entanglement of the curled cord by using a winding type non-stretchable wire with a reel that uses a spiral spring separately from the curled cord, and prevents the curled cord from being twisted or entangled. The product is guided by the force of winding the wire by the reel so as to return the product to its original position. Also, by detecting the wire stopper, it is possible to reliably count the number of times the customer picked up the displayed product. [Selection drawing] Fig. 12

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tethered anti-theft device that connects an anti-theft device main body and a sensor with a curled cord.

In a tethered anti-theft device, the sensor is attached to the target product with a cord from the main unit. I had a lot to do. For example, in the form of Non-Patent Document 1, a curled cord with a thicker cord itself was sometimes used as in Non-Patent Document 2 in order to make it more difficult to get tangled. In addition, curled cords are often used for connecting telephone receivers, etc., and Patent Documents 1 and 2 are disclosed for preventing them from getting entangled. Also, in the function that counts how many times a customer picks up an item, miscounting may occur if the item is not returned to its original position.

When attaching a sensor of a mooring type anti-theft device to an exhibited product, the sensor is often attached with an extendable curled cord so as not to interfere with the customer's movement to pick up the exhibited product. In this case, elongation (defective return), twisting, or entanglement occurs due to excessive pulling of the curled cord. A method of passing a flexible or stretchable core material through the curl diameter of a cable is already known, but because of its flexibility and stretchability, it adapts to the movement of the curled cord and twists and bends to form a curled cord. There was a concern that twisting or the like would occur together. In addition, if the strength of the pull is made weaker so that the customer does not feel uncomfortable, there is also the inconvenience that the product that has been picked up does not return to its original position, making the display cluttered and affecting the aesthetic appearance. In this case, the function that counts the number of times a customer picks up the product cannot be counted correctly, causing an error. If the pulling force is increased to improve the return of the product, the customer will feel uncomfortable when picking up the product, and it is dangerous if the core material is cut. By using a non-stretchable material for the reel winding type wire, the curled cord stretches more reliably, eliminating twisting and tangling, and guiding the product to return to its original position for a beautiful display. It is intended to solve the drawback of worsening the

In this invention, the curled cord connected to the sensor has a separate wire that does not expand and contract through the curl diameter to prevent tangling, etc., and a stopper provided on the wire prevents the wire from being wound too much, and counts the number of pullouts. to implement. The problem is solved by assisting the return of the curled cord with the force of winding the wire with the spiral spring type reel, and guiding the product to be returned to its original place.

As described above, according to the present invention, a wire made of a non-stretchable material is used separately from the curl cord to improve the entanglement of the curl cord. , The expansion and contraction of the curl cord can be adjusted by adjusting the length of the cable, the diameter of the reel, and the design of the spiral spring structure. Operation of the preventive device becomes possible. In addition, since the wire stopper is detected to count the number of times the product is picked up by the customer, it is possible to accurately count even if the position of the product itself is slightly misaligned.

The main body of the tethered anti-theft device has a substrate functioning as a security device and a mechanism for winding wires, and the power source may be a built-in small battery or may be supplied from the outside. Circuits such as "sensor detection", "alarm sound generation", "LED display", and "control" are mounted on the board, and the wire winding mechanism includes "spring", "reel", "reel shaft", "wire", and "stopper". ”, etc., and housed in the housing. The wire used is a twisted wire of thin stainless steel wire that does not expand and contract but is flexible. By fixing the tip of the wire to the sensor side end of the curled cord, the winding force of the wire is transmitted to the curled cord. By assisting the return of the wire and avoiding entanglement, etc., and detecting the stopper attached to the wire, it is possible to obtain information on the exact number of times the customer has picked up the product.

An embodiment will be described below with reference to the accompanying drawings. In the existing mooring type anti-theft device, a main body 1 and a sensor 4 attached to an exhibition product 3 are connected by a curled cord 2. - 特許庁When the sensor 4 operates, the tethered anti-theft device body 1 generates an alarm. The curled cord 2 expands and contracts according to the movement of the customer holding the exhibited product 3. Curl cord 2 usually looks like curl cord (normal) 5, but as you use it, it becomes like sensor cord (twisted example) 6 or sensor cord (entangled example) 7. The expansion and contraction of the curled cord deteriorates, and the appearance of the exhibition is also affected.

There is a corresponding example in which the cord itself is thickened like the curled cord (thickened example) 8 so that the curled cord is less likely to get tangled.

In Utility Model No. 3057632, there is an example in which a flexible shaft 9 is passed through the diameter of the curl cord 2, but since the flexible shaft 9 does not expand and contract, when the curl cord is stretched, only a part of the curl cord is covered. This results in a state in which there is no shaft 9 having flexibility.

In Japanese Patent Application No. 2011-60548, there is an example in which a stretchable flexible rope 11 made of silicone rubber or the like is passed through the diameter of the curl cord 2 and both ends are fixed. There is concern that entanglement may occur.

In the tethered anti-theft device of the present invention, the housing 15 accommodates the wire winding mechanism and the substrate 19 of the security device. The power source for the substrate 19 can be a method of mounting a battery or a method of supplying it from the outside. In the mechanism, a spiral spring 17 is attached to a reel 16 and a reel shaft 18, and a wire 3 is wound around the reel 16. - 特許庁When the wire 3 is pulled out, the cord reel to which the spiral spring 17 is fixed on the other side rotates around the reel shaft 18 to which one side of the spiral spring 17 is fixed, and the wire is pulled out while the spiral spring 17 is wound. A rotating force is generated in the reel 16 in the direction of winding the wire by the force of the coiled spiral spring 17 trying to return. The wire 3 pulled out by this force is wound around the reel 16, and the stretched curled cord 2 is returned to its original position. A stopper 14 is attached to the wire 3 so that it is not wound more than necessary (the curled cord is not pulled too much). count the number of times the For counting, a magnet 21 is built in the stopper 14 and detected by a magnet detection element 22, or a reflected light from the stopper 14 is detected by a reflective light detection element 23, or the like.
