Definitions

  • the invention relates to an article security element which has at least one soft magnetic metal strip.
  • Article security elements of the type mentioned at the outset are known, for example, from EP-PS 0 123 557.
  • the strength of the response field emitted by the security label depends on the direction of the security label in relation to the query field. Did he Strips of soft magnetic metal in the same direction as the interrogation field, so that the magnetic axis of the strip is in the direction of the interrogation field, the entire strip is remagnetized with the frequency of the interrogation field and can therefore emit an electromagnetic response field, which is designed as a receiver coil Magnetic field sensor is detectable. If the strip and thus also its magnetic preferred direction is at right angles to the interrogation field, this field is not able to re-magnetize the strip so that the strip does not emit a detectable response field and the stolen article is not detected by the receiver coil.
  • the soft magnetic metal strip is wound in the form of a helix on an elongated, columnar support body made of non-magnetic material with a pitch angle ⁇ , which has a value between 30 ° and 60 °. It is thereby achieved that a part of the metal strip assumes an angle with each position of the article securing element with respect to the query field which is less than or equal to 60 °. In experiments, this angle has emerged as the angle of a metal strip with respect to an interrogation field at which the metal strip is remagnetized and emits a response field that can be detected with a high probability by a magnetic field sensor. A response field that can be detected with certainty is emitted by the metal strip when the pitch angle ⁇ is between 40 ° and 50 ° and has a value of 45 °, for example.
  • a carrier body which is designed as a cylinder, as a cylindrical hollow body or as a tube, enables simple and efficient production of the article security element according to the invention using a type of lathe in which the cylindrical body can be clamped and wound.
  • a carrier body for the soft magnetic metal strip which is cuboid, can be produced in a simple and inexpensive manner by cutting it off from an elongated strip of non-magnetic material with sufficient thickness, for example by sawing it off.
  • the article security element according to the invention emits a strong and certainly easily detectable response field if the metal strip winding has one turn or if it consists of two half turns which are wound in opposite directions and helically on the carrier body.
  • the carrier body is designed as a hollow body and has in its interior a locking device for a needle for fastening the article security element to articles to be secured against theft.
  • the article security element is very easy to secure against theft To fasten textiles.
  • the article security element 1 shown in FIG. 1 consists of a cylindrical carrier body 2 made of a non-magnetic material, such as, for example, plastic, which can be designed as a solid body, as a hollow body or as a tube.
  • the exemplary embodiments of the carrier body shown in FIGS. 1 to 5 are designed as solid bodies.
  • the article securing element 1 is oriented such that a query field acts on the element 1 in the direction of the arrow 5, the angle between the beginning or the end of the metal strip winding 3 and the field 5 is almost 0 °. If a query field acts in the direction of arrow 6 on the article securing element 1, the middle part of the metal strip winding 3 shown in broken lines in FIG. 1 has an angle of almost 0 ° with respect to the field 6.
  • This angle is of particular importance, because tests have shown that a straight strip of soft magnetic metal, which is at an angle of more than 60 ° with the connecting line between a transmitter coil and a receiver coil of an article surveillance system, does not trigger a theft alarm if it is connected to a high-frequency electromagnetic interrogation field is irradiated, whereas an alarm is most likely to be triggered if this angle is less than 60 °. In addition, has show that such an alarm is triggered with absolute certainty when this angle has a value between 40 ° and 50 °, for example. 45 °.
  • the metal strip as shown in FIG. 2, is designed as a winding with two half turns 7 and 8, which are wound onto the carrier body 2 in opposite directions, but also helically, with a pitch angle of 45 °. If the half turns 7 and 8 touch or cross, they form an angle of 90 ° with one another.
  • both windings 7 and 8 assume an angle of 45 ° with respect to an electromagnetic interrogation field that is in the direction of the axis of symmetry 4 or perpendicular thereto, so that both windings 7, 8 react actively to such a field and trigger an alarm.
  • a field in the direction of arrow 5 only acts on the winding 8 and a field in the direction of arrow 6 only on the winding 7 such that the metal strips are remagnetized by the interrogation field and trigger theft alarm.
  • Fig. 3 shows an embodiment of an article security element 9 with a cuboid carrier body 10, which can be produced by cutting off corresponding pieces from an endless belt made of plastic with a sufficient thickness, i.e. sawing them off.
  • the embodiments 12 and 13 differ in that the turns 14 and 15 intersect in the embodiment 12 on one edge of the carrier body 10 and in the embodiment 13 on its front surface.
  • FIG. 6 shows an article securing element which consists of a tubular carrier body 16, in the interior of which a locking device for a needle 17 with a button-shaped needle head 27 is arranged.
  • a cylindrical body 18 with a conical cavity 19 is firmly inserted in the interior of the carrier body 16 and has a first round opening 20 for the needle 17 and a second round opening 21 on the side opposite the first opening 20 for a tubular holding body 22, which is fixedly connected to a magnet 23 mounted movably in the carrier body 16 and whose function consists in holding balls 24 and 25 and by means of the force exerted by the spring 26 on the magnet 23 into the conical taper of the conical Press cavity 19.
  • a needle inserted into the opening 20 presses the balls 24 and 25 and thus also the magnet 23 downward against the force of the spring 26 via the holding body 22.
  • the needle 17 penetrates into the interior of the holding body 22.
  • the magnet 23 movably mounted in the carrier body 16 and thus also the holding body 22 are pulled downward, so that the balls 24 and 25 no longer exert a clamping effect on the needle 17.
  • the needle 17 can now be removed from the locking device as long as the unlocking magnet acts on the movably mounted magnet 23.
