Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a safety clip for protecting textile products and other goods from theft. The safety clip has two spring biased clip legs, the first clip leg includes a switch responsive to pressure, and the suppressable actuator is connected to the second clip leg. The facing projections projecting from the clamping surfaces of the clip legs form a curved passage for the web to which the safety clip is secured in the closed position.

[Conventional technology]

Stores that sell textiles and furs are at risk of shoplifting. In order to eliminate this danger, it is known to protect items that are put up for sale with a special lip. This clip is connected to an electrical monitoring device via a wiring cable. The clip includes a switch, the actuator of which is pressed by a fabric or fur product fastened between the clip legs. The actuator enters a recess in the opposite clip leg once the safety clip is removed. When pressure is no longer applied to the surface of the switch key (actuator), an alarm is generated in the monitoring device. A skilled shoplifter will overcome such safety clips by inserting a relatively stiff plastic card added to the fabric of the textile product into the gap between the clip legs. The clip is then opened, but the plastic card takes over the role of pressing the switch, without affecting the pressure that was being exerted on the key surface of the switch.
The safety clip will be removed from the article to be protected along with the rigid cart or plate pressing the switch. In other words, the theft protection system is unaware that the safety clip has been removed from the item to be protected. Since this method allows conventional safety clips to be switched off by inserting a simple plate or sheet, experienced shoplifters have a method for removing clothing from the safety clip without interfering with the switch operation. Because of this knowledge, its effectiveness is significantly reduced.

DE 2912008 discloses a safety clip with a switch on each of the two clip legs. The actuators of the switch extend parallel to each other and spaced apart in overlapping relationship. The ends of these clip legs are provided with ridges offset from each other, which impart a sliding shape to the fabric web to be fastened by the safety clip. Even by this means, illegal acts cannot be eliminated. This is because the actuators of the switches are accessible from the side and they can be pressed by a flat object, allowing the textile fabric to be gently pulled out from between the actuators without one of the switches responding. Because you will get it.

Another known safety clip includes a second clip leg with a star-shaped pressure jaw for forcing the fastened fabric web toward the actuator of the switch. A flap attached to the end of this second clip leg biases the secured textile web. In this case as well, it is possible to slide a flat object between the clip legs while keeping the switch operational, and the fastened fabric (textile web) can be removed without being noticed by the safety clip.

[Problem that the invention seeks to solve]

This invention has been made to solve the above-mentioned problems of the prior art and makes it impossible to continue pressing the switch with an inserted object to pull out the fastened web without an individual response from the switch. The purpose of this product is to provide a safety clip.

SUMMARY OF THE INVENTION The present invention solves this problem by including a pivoted disc in which the second clip leg contacts the fastened web. The protrusions of the first and second clip legs surround the actuator, and when the clip is in an empty and closed state, the protrusions of at least one clip leg are connected to the other clip leg without actuating the switch. It comes into contact with the clamp surface of the part.

According to the invention, the two clip legs have a projection that projects towards the other clip leg. The protrusions are arranged on both clip legs such that they do not abut each other, but the protrusions on one clip leg engage the non-protruding areas of the other clip leg. A protrusion on both clip legs is arranged around the switch actuator to prevent flat objects from being inserted sideways into the safety clip unless the clip legs are separated and the switch is actuated. do. Irrespective of the thickness of the fastened fabric or fur web, the disc is such that it always lies parallel to the clamping surface of the first clip leg, thereby preventing illegal insertion into the closed safety clip. guarantees the same protection from all outer circumferential sides.

According to a preferred embodiment of the safety clip of the invention, the protrusion of the first clip leg protrudes at least as much as the actuator. Because of the protrusion, which may consist of a ring that is closed or intermittent (e.g. a circle of individual protrusions), the actuator is not continuously pushed by an inserted flat hard object. It becomes like this. For example, a protrusion or protrusion may cause an inserted flat plastic card to be spaced from the first clip leg such a distance that it cannot press the actuator for operating the switch. On the other hand, a soft fabric or fur material will press against the actuator as the protrusion is pressed into the fabric or fur. Therefore, the switch responds only to soft materials that can be compressed, rather than a rigid plate or soft paper that cannot be compressed sufficiently.

Typically, the materials that respond to the switch are too soft to be added to the fastened fabric and easily introduced by a shoplifter into the safety clip, and such an attempt would at least - is activated and an alarm sounds. The safety clip of the present invention thus protects the article attached thereto from unauthorized removal.

In accordance with the principles of the invention, each clip leg includes a protrusion surrounding an actuator. This protrusion need not be a continuous ring, but may consist of a plurality of protrusions distributed around the actuator to form an intermittent ring. These multiple protrusions arranged in a circle,
For simplicity of explanation, it will also be referred to as a "protrusion". These projections individually extend into the web a small distance, while the actuator surface facing the web is relatively wide and due to its flexibility is pressed by the web to actuate the switch.

Preferably, the protrusion of the disk of the second clip leg may consist of a protruding border which surrounds the tip of the protrusion of the first clip leg when the safety clip is closed, It is not possible to insert a flat card into this safety clip without opening the section. Alternatively or additionally, the protrusion of this disc is the protrusion of the first clip leg.
may consist of a ring with a smaller diameter than the circle formed by.

In a preferred embodiment of the invention, the actuator comprises a repressible pin capable of moving laterally on its longitudinal axis, which in a depressed state imparts a lateral movement across its longitudinal axis. and turn off the switch. Once the textile material is secured by this clip, the pin is pushed in the direction of its warp axis into the switch. When an attempt is made to insert a card between the clip legs parallel to the textile material, the edge of the card hits the pin of the switch and moves it transversely to the longitudinal axis. As a result, the switch state previously produced by the textile material is canceled while the actuator pin remains pressed. In this way, protection against illegal operations is expanded.

According to a preferred embodiment of the invention, the disc includes an appendage aligned with the actuator, the height of the appendage being such that the actuator is just not actuated when the safety clip is empty and closed. It has a great height. This attachment prevents the introduction of rigid cards between the closed clip legs.

This attachment may include a spike that hides in a recess in the switch element (actuator) when the safety clip is closed. Further, the spikes and the depressions may be provided in a reverse relationship.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The illustrated safety clip 10 has two U-shaped legs 11 , 12 hinged by a connecting shaft 16 . A spring 14 mounted on this shaft 16 separates and widens at the rear end of the clip leg 11.12.
Their front ends are pressed together.

At the front of the first clip leg 11 is an electric switch 15.
is fixed, its actuator 16 facing the other clip leg 12. The switch 15 is mounted inside the first clip leg 11 and is covered by a plate 18 with a hole 17 for the passage of the actuator 16. The plate 18 is provided with raised means (19) consisting of a plurality of protrusions 19 arranged in a circle around the actuator 16 and projecting towards the second clip leg 12.
A protrusion) is provided.

As is clear from FIGS. 4 and 5, the pin-shaped actuator 16 may not only be pushed into the switch 15, but also swivel laterally within the hole 17. It's okay. Actuator 1
When 6 is pushed in the axial direction, switch 15 is actuated.

When actuator 16 is moved sideways, switch 15 is disabled. In other words, an attempt to slide a flat object parallel to the web 26 between the clip legs will cause the edge of that object to strike the actuator 16 and cause the switch 15 to be disabled (opened). ), the actuator assumes an inclined position. The rest position or deactivation of the switch corresponds to the opening of the clip or the absence of a web between the clip legs.

The second clip leg 12 is provided with a holder 20 which has a disc 2 attached thereto by means of a pole joint 22.
1 is installed. The disk 21 is made of a plate that can be rotated swivelly by the rotation of a ball joint 22 located at the center in the vertical direction of the clip, and is adjusted so that it is always parallel to the plane in which the protrusion 19 is located. This allows the disc 21 to be adapted to any thickness of the web 26 sandwiched between the clip legs 11.12. The diameter of the disc 21 is the protrusion 19
This ensures that each protrusion 19 of the first clip leg 11 faces the surface of the disc 21 of the second clip leg 12.

Referring to Figure 5, the safety clip is empty and closed (
That is, if there is no web 26 to be clamped), the protrusion 19 is in contact with the clamping surface 26 of the disk 21. This clamping surface 26 is surrounded by a continuously surrounding high border 27. A tall ring 28 concentric with the border 27 extends inside the circular part in which a projection 19 of the first clip leg 11 is located, which projection 19 projects into the space between the border 27 and the ring 28. It looks like this.

The ring 28 surrounds a recess 29, the bottom of which is deeper than the clamping surface 26. An appendage 30 of lower height than the ring 28 protrudes from the recess 29 and is aligned with the actuator 16, with the actuator 16 at the top of the appendage 30 when the safety clip is empty.
are just touching, and the switch 15 does not operate. Attachments 30
A vertical spike 31 provided in the center of the actuator 16 extends into a recess 32 provided in the end face of the actuator 16 .

As shown in FIG. 4, under the action of the spring 14, each protrusion of the protrusion 19 enters into the web 23, and the lower surface of the web 23 is pressed against the clamping surface 26, while the boundary 27 and ring 28 It is transformed by undulations between the two. Due to the appendage 60, the web 23 is lifted into the area of the actuator 16. Although the end face of the actuator 16 in the rest state does not extend beyond the projection 19, this actuator is pushed into the switch 15 by the protruding web and activates the switch 15.

When an attempt is made to slide the IJ knob, the hard strip is supported on the projection 19 and the switch 15 is turned off. That is, there is no force being pushed by the actuator 16 or by a hard flat strip.

Via a cable 24, the switch 15 is connected to an electrical monitor 25. This cable is of the four-wire type and includes, in addition to the signal circuit through switch 15, a second circuit monitored for resting current. In other words, it is impossible to fool the monitor 25 by short-circuiting the two wires of the cable 24 outside the switch.

The safety clip switch 15 of the invention has a soft depressable material between the clip legs 11.12;
It is activated only when the protrusion 19 can fit into it. However, such soft material cannot be maliciously inserted into the safety clip when the web 26 is present within the clip.

Experiments have shown that the switch does not respond when sheet metal, plastic card, or paper enters between the clip legs, but responds to the presence of textile materials.

Such textile materials may be of relatively reduced thickness. In practice, for example, the switch already responds to canvas or silk fabrics.

〔Effect of the invention〕

As described above, according to the present invention, the protrusions provided on the two clip legs constituting the safety clinop surround the actuator of the switch, and the disk serving as the web receiver of one clip leg is the pivot point. Since it is movable, it is possible to prevent flat objects from being inserted between the clip legs from any direction. Therefore, products with web-like materials, such as textile products or fur products, can be effectively protected from theft by fastening them with this safety clip.
