Abstract

Anti-theft label device including a trap circuit (LC), as well as a piece of metal with very high magnetic permeability. This label is thus capable of being detected either by an anti-theft device using the radio frequency detection method or the method of detection by alteration of a magnetic field.

Description

La présente invention concerne un dispositif d'étiquette alliant les propriétés des étiquettes constituées d'un circuit bouchon (LC) et des étiquettes constituées par un métal de forte perméabilité tel que le Permaloy ou les amorphes. The present invention relates to a label device combining the properties of labels consisting of a plug circuit (LC) and labels consisting of a metal of high permeability such as Permaloy or amorphous.

On connaît déjà des dispositifs d'étiquettes antivol constitués d'un circuit bouchon et qui sont détectables par un dispositif antivol basé sur le principe de la radio-fréquence : Brevets

US 4021705, US 4567473, US 4728938, US 4835524, US 4689636,
Ces dispositifs d'étiquettes antivol sont cependant incapables d'être détectés par un procédé de repérage par modification d1un champ magnétique tel que décrit dans le brevet français n 763681. Anti-theft label devices are already known which consist of a plug circuit and which can be detected by an anti-theft device based on the radio frequency principle: Patents

US 4021705, US 4567473, US 4728938, US 4835524, US 4689636,
These anti-theft label devices are however incapable of being detected by a method of identification by modification of a magnetic field as described in French patent n 763681.

On connaît également des métaux à forte perméabilité tel le
Permalloy ou des alliages tels que les amorphes dont les propriétés magnétiques les rendent propices a être utilisés comme étiquette de marquage avec les dispositifs antivol utilisant un procédé de repérage des articles protégés par modification d'un champ magnétique : Brevets : France n 763681, US 3820103, US 3820104,

US 4309697, US 457152, US 4539558, US 4859991.Metals with high permeability are also known, such as
Permalloy or alloys such as amorphous whose magnetic properties make them suitable for use as a marking label with anti-theft devices using a method of locating articles protected by modification of a magnetic field: Patents: France n 763681, US 3820103 , US 3820104,
US 4298862, US 4300183, US 4118693, US 4123749, US 4074249,

Les dispositifs de marquage constitués de ces métaux sont incapables d'être détectés par les dispositifs utilisant le principe de la radio fréquence décrit pour exemple dans les
Brevets : US 3624631, US 4243980, US 421808.Marking devices made of these metals are incapable of being detected by devices using the radio frequency principle described for example in
Patents: US 3624631, US 4243980, US 421808.

Pour des raisons de discrétion, les étiquettes détectables par le procédé magnétique sont, dans la plupart des cas, constituées d'une fine bandelette de métal à forte perméabilité initiale d'une longueur comprise entre 3 et 10 cm . Cette disposition dans un seul
plan ne permet pas une très bonne détection, notamment quand la
bande de métal est dans un plan vertical.For reasons of discretion, the labels detectable by the magnetic process are, in most cases, made up of a thin strip of metal with high initial permeability of a length between 3 and 10 cm. This layout in a single
plan does not allow very good detection, especially when the
metal strip is in a vertical plane.

Par construction et par cause d'encombrement il est difficile d'envisager des dispositifs capables de détecter une bande de métal parfaitement dans tous les plans. By construction and because of space it is difficult to envisage devices capable of detecting a metal strip perfectly in all planes.

Le but essentiel de la présente invention est de réaliser une étiquette de marquage dite 'universelle capable d'être détectée à la fois par un dispositif utilisant le principe de la radio fréquence, ainsi que par une dispositif utilisant le procédé de repérage des articles par modification d'un champ magnétique.  The essential aim of the present invention is to produce a so-called 'universal marking label capable of being detected both by a device using the radio frequency principle, as well as by a device using the method of locating articles by modification. of a magnetic field.

L'intêret de cette invention réside dans le fait que l'étiquetage "a la source" devient beaucoup plus souple. En effet, une chaîne de magasins, conditionnant ses marchandises dans un entrepôt centralisé et possédant à la fois des dispositifs antivol radio fréquence dans certaines de ses succursales de vente et des dispositifs utilisant le principe magnétique dans d'autres succursales, utilise maintenant un seul type de marquage. Cela 'évite des confusions, des erreurs et un stockage trop important. The advantage of this invention lies in the fact that labeling "at the source" becomes much more flexible. Indeed, a chain of stores, packaging its goods in a centralized warehouse and having both anti-theft radio frequency devices in some of its sales branches and devices using the magnetic principle in other branches, now uses only one type marking. This' avoids confusion, errors and too much storage.

Les différentes succursales de vente peuvent également s'échanger sans restriction les marchandises déjà protégées par étiquetage antivol. The various sales branches can also exchange without restriction the goods already protected by anti-theft labeling.

Selon la caractéristique essentielle de l'invention, représentée par la figure 1, l'étiquette de marquage comporte à la fois un circuit bouchon (LC) formé par un bobinage inductif (1) ainsi qu'une capacité (2), et une pièce de métal (3) à perméabilité initiale très élevée. According to the essential characteristic of the invention, represented by FIG. 1, the marking label comprises both a plug circuit (LC) formed by an inductive winding (1) as well as a capacitor (2), and a part of metal (3) with very high initial permeability.

Selon une deuxième caractéristique de l'invention, la pièce de métal (3) est disposée en forme de cornière de façon à être détectée dans toutes les positions par les dispositifs antivol utilisant le procédé magnétique. According to a second characteristic of the invention, the metal part (3) is arranged in the form of an angle so as to be detected in all positions by the anti-theft devices using the magnetic method.

En effet, lorsque l'un des côtés de la cornière est confondu dans un plan vertical, l'autre côté est forcément confondu dans un plan horizontal. Une bonne détection est donc conservée dans tous les cas. Indeed, when one of the sides of the angle iron is merged in a vertical plane, the other side is necessarily merged in a horizontal plane. Good detection is therefore retained in all cases.

Pour des raisons pratiques, l'invention est utilisée dans la plupart des cas, sous forme détiquette autocollante ; mais ce n'est pas une obligation.  For practical reasons, the invention is used in most cases in the form of a self-adhesive label; But this is not an obligation.
