Definitions

  • the invention relates to a device for securing Anti-theft articles, consisting of a housing and a securing element arranged in the housing. Furthermore, the invention relates to a method to manufacture the device according to the invention and on a device for performing the invention Procedure.
  • a device is already from the prior art - a so-called Hard Tag - became known, which consists of two in there are essentially identical halves. On the A strip element is made on the inside of one half glued on soft magnetic material. Then be the two halves put together, and the hard tag will be by means of a releasable pin on one to be secured Article, for example attached to a piece of clothing.
  • the response signal to an external magnetic field is at a maximum if the preferred axis of the securing element is aligned parallel to the field.
  • the response signal disappears when the external magnetic field is perpendicular to the preferred axis of the securing element.
  • two strip elements are therefore oriented in a cross shape to one another in the prior art.
  • the soft magnetic strip or the soft magnetic wire must have a certain length. Since a hard tag has its largest diameter in the central area, the stripe elements run in the central area.
  • the fastening mechanism is usually designed to be magnetic, with relatively high magnetic fields being required to detach the fastening pin from the article.
  • An example of such a fastening mechanism has become known, for example, from EP 0 132 531 B1.
  • the invention has for its object an electronic propose detectable fuse element that is characterized by a high detection rate. Still lies the invention has for its object an inexpensive Manufacturing method and a device for carrying it out to present the procedure.
  • the securing element has approximately closed form.
  • the securing element is ring-shaped or elliptical educated.
  • the strip is due to the curved, in itself closed form so long that it is sufficiently strong Response signal to an external magnetic field. Furthermore, the securing element is so far from that Mounting mechanism removed that its magnetic Condition due to stray fields of the locking mechanism is adversely affected; and third is the detection rate especially with a circular configuration of the Securing element regardless of the orientation to outer field.
  • the device provides that the securing element is in one piece is formed or that it consists of at least two individual elements consists essentially in an annular or elliptical shape. It has it turned out that the arrangement of the individual elements there is essentially nothing in the gap Functionality of the device according to the invention changes.
  • the Fastening mechanism for hard tags usually on magnetic base.
  • To detach the hard tags from the Secured items are relatively high magnetic fields required. These fields usually magnetize the magnetic locking mechanism, which in turn a nearby securing element via a stray field negatively influenced.
  • the distance of the securing element from the Fastening mechanism is selected as possible.
  • the housing at least two parts exist that there is an attachment mechanism has and that the securing element one in substantially constant distance from the fastening mechanism having. Because of the great distance from that Attachment mechanism will change the magnetic state of the Security element not or hardly by stray fields of the Locking mechanism 'affected.
  • the securing element is preferably a wire or around a strip. It goes without saying it is also possible to get the shape you want from a punching out the soft magnetic layer - a method that however, is associated with relatively high material losses.
  • the following advantageous embodiment is in the housing suggested: there is one on the inside of the housing circular, elliptical or other type of guidance provided, and the securing element lies against this on.
  • the guide can be a groove or a Survey acts, the survey as a continuous or interrupted bead can be formed.
  • the securing element is at least on the corresponding part of the housing fixed at certain points.
  • the task is thereby regarding the procedure solved that the securing element in the form of tape material is provided and that the tape material in a closed form is fastened in the housing.
  • a dispensing device is provided, which the securing element in the form of tape material provides; furthermore is a rotation unit provided on which a part of the housing is mounted; the Dispensing device is above the rotating part of the Arranged housing and placed the fuse element ring-shaped during a rotation of the rotation unit or in another self-contained form on the Inside of the housing part.
  • the dispensing device a cutting device is assigned, the provides the tape material in a desired length. Furthermore, an adhesive device is provided which Securing element at least selectively on the part of the Housing attached.
  • Fig. 1 shows a plan view of a first embodiment of the device according to the invention in the unassembled state.
  • the device 1 consists of two essentially identical halves 2a, 2b which are firmly connected to one another in the assembled state.
  • the device 1 is fastened to an article to be secured via the fastening mechanism 4.
  • the securing element 3 is arranged according to the invention in a self-contained form. In the case shown, the shape is a ring.
  • the securing element 3 it is not necessary for the securing element 3 to consist of one part, rather it can consist of a plurality of sub-elements 3a arranged in a gap from one another.
  • This configuration considerably simplifies the assembly of the securing element 3 in the device according to the invention. As can be seen in FIG. 2, it is sufficient to fix the securing element 3 if the guide consists of individual projecting elements.
  • the securing element 3 is as Tape material 8 wound on a supply roll 13 and is successively provided by the dispensing device 9.
  • the beginning of the strip material 8 is in a clamping part 14 fixed on the housing part 2a and during the subsequent rotating process of the rotary unit 10 circular or in the desired shape on the Housing part 2a placed. Is it the Band material 8 around a strip material, so this lies with the edge on the housing part 2a and with the flat side at the guide 5.
  • a fixation of the securing element 3 on the guide 5 or the housing part 2a is carried out by means of an adhesive donated by the gluing device 12.
