Abstract

A security zipper comprising two fastener tapes (11, 12) having interdigitated teeth (13) and a slider (20) slidable along the fastener tapes for opening and closing, the slider having a catch element (25), characterized in that an end piece (17) for holding the catch element in the closed position of the slider (20) is provided at one end of the zipper, and in that the end piece (17) has a concealed release member for releasing the catch element (25).

Description

The The invention relates to a security zipper with two fastener tapes, the interlocking teeth and a slider for opening and closing along the fastener tapes is displaceable, wherein the slider has a catch element.

In DE 609 05 708 T2 a zipper with two sliders is described, which are coupled relative to each other. Both slides engage relative to each other when they are pressed against each other. The slides can be separated again by pulling apart when a preload force is overcome.

In EP 0 280 071 B1 a zipper is described, the slider has a hook, which cooperates with an eyelet, which on an object, for. B. a bag attached. In this way, the slider of the zipper can be locked in the end position relative to the bag. The locking is released by actuating a release member, for example with a pointed pin.

Often Handbags are opened unnoticed by pickpockets and the handbag contents are stolen. This is because of that the zipper closing the bag no or only insufficient protection against unauthorized opening offers.

Of the Invention is based on the object, a security zipper to create, especially for handbags or others Carrying bags is suitable and unauthorized opening almost impossible power.

Of the Security zipper of the present invention is defined by the claim 1. He is characterized in that at one end of the zipper a tail for holding the catch of the slider in the closed position of the slider is provided and that the tail to the Release the Fangelements a concealed dissolving organ having.

Of the inventive safety zipper has at the closure end an end piece in which the catch element the slide automatically engages when the slider is brought into the closed position. So the user has to just completely pull the zipper, so that the lock becomes effective. By just pulling up can the zipper will not be opened anymore. Rather, to open the operation of the release member required. This is arranged face down. It is either from the housing of the tail covered or it is arranged so that it is not readily visible or can not be easily operated. A thief can The dissolving organ can not reach without this from the user is noticed. The invention enables a mechanical automatic blocking or blockage of the slide by Engaging in the end position. The advantage is that a Handbag or shoulder bag in large crowds by unauthorized persons should not be opened unnoticed.

Preferably the catch element is a projecting from the slider tongue, the insertable into a guide groove of the tail is. The catch element may have a hole in which a resilient pin of the tail engages. Alternatively, the catch element have a cam which is in a guide groove on the tail einfährt and in a depression on the groove bottom of the guide locks.

According to one preferred embodiment of the invention, it is provided that a Actuation of the release element only with a sharp point Tool is possible, for example with a ballpoint pen, the is pressed into a hole opening of the tail and in the depressed state, the release element in the Release position presses.

in the The following will be an embodiment with reference to the drawings the invention explained in more detail.

It demonstrate:

1 a perspective view of the end portion of a safety zipper according to the invention during tightening and

2 a top view of the zipper during winding.

The safety zipper 10 has two fastener tapes 11 . 12 on, those with interlocking teeth 13 are provided in a known manner. The fastener tapes 11 . 12 are each on a side strip 14 respectively. 15 fastened, which in turn is sewn to the body of a bag. At the end of the closure 16 the zipper is an end piece 17 Firm with the two fastener tapes 11 . 12 connected is. The closure piece 17 has a substantially closed housing 18 on, that at a introductory a guide groove 19 contains, which is open at the bottom.

Along the fastener tapes 11 . 12 is a slider 20 slidable, the teeth 13 locked relative to each other when displaced in the longitudinal direction of the zipper. Of the Slider has in a known manner an eyelet 21 on which an actuating part 22 is attached as a handle. By grasping the operating part 22 the slide can be moved.

At the tail 17 facing the end of the slide 20 there is a catch element 25 in the form of a protruding from the slider tongue, in the guide groove 19 of the tail 17 can penetrate. The tongue may be formed as a flexible leaf spring. She has a hole 26 or a recess in which a (not shown) pin of the tail 17 can engage. Alternatively, the catch element 25 also have a cam which is in the guide groove 19 enters and engages in a depression on the groove bottom of the guide groove. In any case, the tail contains a trap in which the catch element 25 locks. The loosening of the trap is done with a tool that is in a hole 28 on the housing 18 of the tail 17 is inserted and there presses against an elastic release member which releases the lock. The hole 28 has a small diameter of 2-3 mm. It is sized so that the tip of a ballpoint pen refill can be inserted, which can then be used as a tool for releasing the lock. Alternatively, of course, a special pen can be used for this purpose.

The opening of the zippered bag is only possible when the release member through the hole 28 is pressed through, associated with simultaneously pulling the slider 20 , In the described embodiment, the catch element 25 , which is designed as a resilient tongue, at the same time represent the release organ or wear this release organ.

The Invention offers the advantage that when closing the zipper up to the end position of the slide in at the same time a lock or Blocking of the slide takes place. This will be with handbags Thefts are largely prevented.
