DESCRIPTION:

BRIEF SUMMARY
The invention relates to a method for securing goods against theft according to the preamble of the dependent claim and a device for carrying out the method with a securing element and release apparatus.
On the market magnetically releasable theft securements are known and widely employed. The goods to be protected, for example clothes are provided with a distinguishing mark, a so-called tag. This tag consists of a retaining part and a pin which is inserted through the goods and retained in the retaining part. The pin and retaining part are thus unreleasably attached to the article to be protected. The pin in the retaining part is secured against withdrawal in that it is pushed through two wedging elements in the form of flat or curved metal platelets which wedge against one another and thus with respect to the pins. The wedging is effected by way of a slight spring force and/or by small balls between the two metal platelets. With a strong release magnet as a release apparatus the metal platelets or the small balls may be pulled laterally from the outside without contact, upon which the pin is released and may be pulled rearwards from the article. The tags may additionally be provided with colour containers and/or with induction coils. In any case they are designed such that a forced separation of the tag from the article leads to a destruction or at least to considerable damage to the article.
All these theft securements do not however protect from the considerable thefts which are carried out by the sales personnel themselves or those with their support. These theft securements may be released with every release magnet or perhaps with any strong permanent magnet without the article getting damaged.
It is the object of the invention to provide a method for securing goods against theft which renders impossible an unauthorised release of such a type of theft securement by using permanent magnets of all types. Likewise a device for carrying out the method belongs to the object of the invention.
The object is achieved by the invention specified in the patent claims.
An additional advantage of the invention is that the release of the theft securement is made dependent on the payment or on a control function at the till.
A further advantage of the invention results in that the theft of goods by way of unauthorised releasing of the theft securements by sales personnel or with the support of personnel is made impossible or at least significantly reduced.
The invention is hereinafter described in more detail in the context of the drawings. There are shown:
FIG. 1 shows a theft securement according to the state of the art.
FIG. 2 shows a theft securement according to the invention in a first variant, in cross section;
FIG. 3 shows an associated release apparatus with an inserted theft securement during the release procedure, in cross section;
FIG. 4 shows a theft securement according to the invention in a preferred variant, in cross section; and
FIG. 5 shows a block diagram of the cooperation and arrangement of the release apparatus, the theft securement, the control and the release function at the till.
The method according to the invention for securing goods against theft is now described in more detail in combination with the FIGS. 1 to 5.
In FIG. 1 a theft securement according to the state of the art is shown. The goods 5 to be protected, for example clothing, with such a theft securement, are provided with a so-called tag as a securing element. This tag consists of a retaining part 10 and a pin 11 which comprises a broad head 12. The pin 11 is pushed through the article and is retained in the retaining part 10 and secured against withdrawal. For this it is pushed through two wedge elements 17, 18 in the form of flat or curved metal platelets which wedge against one another and thus with respect to the pins 11. The wedging is effected under the effect of a retaining force field, here by a slight spring pressure and/or by small balls 19 between the two metal platelets. A spring 19' ensures that the wedging eleme
