Description

L'invention conceme un enrouleur pour fil spiralé, utilisé avec des dispositifs de protection anti-vol pourdes articles présentés en magasin, par exemple des appareils photographiques ou des téléphones.The invention relates to a winder for spiral wire, used with anti-theft protection devices for articles presented in the store, for example cameras or telephones.

Ces dispositifs de protection permettent la manipulation des articles par des acheteurs potentiels, tout en limitant les risques de vol.These protective devices allow the manipulation of items by potential buyers, while limiting the risk of theft.

A cet effet, les dispositifs anti-vol connus se présentent sous la forme d'un détecteur relié, par un circuit électrique, à une centrale d'alarme (voir US 5 124 685).For this purpose, known anti-theft devices are in the form of a detector connected by an electrical circuit to an alarm center (see US 5 124 685).

Le détecteur est destiné à être fixé sur l'article à protéger. Lorsqu'un client indélicat retire le détecteur de l'article, un signal d'alarme est déclenché par la centrale.The detector is intended to be fixed on the article to be protected. When an unscrupulous customer removes the detector from the item, an alarm signal is triggered by the panel.

Le circuit électrique qui relie le dispositif de protection à la centrale d'alarme comporte un fil électrique, dont la longueur est suffisante pour permettre la manipulation de l'article protégé. De plus, plusieurs articles sont généralement disposés sur un même support.The electrical circuit that connects the protection device to the alarm center comprises an electrical wire, whose length is sufficient to allow the manipulation of the protected article. In addition, several articles are generally arranged on the same support.

En cours d'utilisation, on constate que les fils électriques restent apparents sur le support, ce qui est peu esthétique. Par ailleurs, les fils électriques s'emmêlent fréquemment, ce qui rend difficile toute manipulation par les consommateurs.In use, it is found that the electrical son remain apparent on the support, which is unattractive. In addition, the electrical wires become entangled frequently, which makes it difficult for the consumer to handle them.

C'est pourquoi, Il est préférable d'utiliserun enrouleur pour fil électrique.Therefore, it is best to use a wire winder.

On connaît déjà un enrouleur qui comporte une roue sur laquelle le fil peut être bobiné.We already know a winder which has a wheel on which the wire can be wound.

L'enrouleur comprend également un joint tournant électrique qui tourne avec la roue. Ce joint est composé de pistes circulaires et d'un doigt prenant appui sur celles-ci.The reel also includes an electric rotary joint that rotates with the wheel. This seal is composed of circular tracks and a finger bearing on them.

En pratique, une extrémité du fil est reliée à l'objet à protéger.In practice, one end of the wire is connected to the object to be protected.

L'autre extrémité du fil est reliée aux pistes circulaires du joint tournant, le doigt de ce joint étant relié à un fil, lui-même connecté à la centrale d'alarme.The other end of the wire is connected to the circular tracks of the rotary joint, the finger of this joint being connected to a wire, itself connected to the alarm center.

Ainsi, la connexion entre l'article à protéger et la centrale d'alarme est assurée.Thus, the connection between the article to be protected and the alarm center is ensured.

Le fil peut être déroulé lorsqu'il est tiré par un utilisateur. Lorsque la force de traction cesse d'être exercée, le fil devrait être automatiquement enroulé sur la roue, sous l'action d'un ressort.The thread can be unrolled when pulled by a user. When the pulling force ceases to be exerted, the wire should be automatically wound on the wheel, under the action of a spring.

Ce type d'enrouleur, dit enrouleur électrique, n'apporte pas cependant satisfaction.This type of winder, said electric winder, does not bring satisfaction, however.

Tout d'abord, il est de fabrication relativement complexe, du fait de la présence d'un joint tournant électrique. Par ailleurs, l'encrassement des pistes circulaires du jointtoumant conduit à des défauts de connexion avec la centrale d'alarme et la protection de l'article n'est alors plus assurée. Enfin, l'enroulement du fil n'est pas satisfaisant. On constate que l'enrouleur se bloque et une partie du fil reste donc déroulé. Ceci nuit à la bonne présentation des articles présentés en vente.First of all, it is relatively complex to manufacture because of the presence of an electric rotary joint. Moreover, the fouling of the circular tracks of the sealant leads to connection faults with the alarm center and the protection of the article is then no longer ensured. Finally, the winding of the wire is not satisfactory. It is found that the winder hangs and a portion of the wire remains unrolled. This is detrimental to the good presentation of the articles presented for sale.

On connaît également par le modèle d'utilité DE-U-21 542 un dispositif enrouleur de fil spiralé comportant un boîtier dans lequel au moins un galet mobile en rotation autour d'un axe fixe est mis en oeuvre et autour duquel le fil s'enroule.Also known from the utility model DE-U-21 542 is a spiral wire winder device comprising a housing in which at least one roller movable in rotation about a fixed axis is used and around which the wire s' wraps.

Si ce dernier dispositif évite le contact électrique tournant et permet de masquer le fil non étiré, il reste cependant encore relativement complexe à réaliser du fait de la présence de pièces mobiles en rotation, les galets. En effet, Il est nécessaire d'ajuster précisément les éléments de l'enrouleur pour que les axes de rotation soient correctement alignés afin que le galet puisse tourner.If the latter device avoids the rotating electrical contact and allows to hide the unstretched wire, it remains however still relatively complex to achieve because of the presence of moving parts in rotation, the rollers. Indeed, it is necessary to precisely adjust the elements of the winder so that the axes of rotation are properly aligned so that the roller can rotate.

L'invention a pour but de simplifier la fabrication des enrouleurs à fils spirales destinés à des dispositifs de protection antivol, tout en permettant un enroulement satisfaisant du fil dans l'enrouleur.The object of the invention is to simplify the manufacture of spiral wire winders intended for anti-theft protection devices, while allowing a satisfactory winding of the wire in the winder.

L'invention concerne donc un tel enrouleur pour fil spiralé constitué par deux supports à distance l'un de l'autre et au moins un élément de guidage pour le fil, disposé entre les deux supports. Selon l'invention, le fil spiralé a un pourcentage d'allongement après étirement complet compris entre 0 et 50% et l'élément de guidage étant fixe.The invention thus relates to such a winder for spiral wire constituted by two supports at a distance from each other and at least one guide element for the wire, disposed between the two supports. According to the invention, the spiral wire has an elongation percentage after complete stretching between 0 and 50% and the guide element being fixed.

Les caractéristiques suivantes de l'enrouleur peuvent également être prises en considération, isolément ou selon toutes leurs combinaisons techniquement possibles :

  • les deux supports sont sensiblement plans,
  • l'écart entre les deux supports est sensiblement constant,
  • un des supports comporte des moyens de fixation pour une extrémité du fil spiralé, notamment constitués par un orifice pratiqué dans le support,
  • un des supports comporte une ouverture pour le passage de l'extrémité libre du fil.
The following characteristics of the winder may also be taken into consideration, in isolation or in any technically feasible combination:
  • the two supports are substantially planar,
  • the distance between the two supports is substantially constant,
  • one of the supports comprises fixing means for one end of the spiral wire, in particular constituted by an orifice made in the support,
  • one of the supports comprises an opening for the passage of the free end of the wire.

Le pourcentage d'allongement est, de préférence, compris entre 0 et 10 %.The percentage of elongation is preferably between 0 and 10%.

Cet ensemble a l'avantage de présenter une forme compacte.This set has the advantage of having a compact shape.

L'invention conceme donc un ensemble constitué par un dispositif de protection anti-vol pour un article de présentation, des moyens électriques reliant le dispositif à une centrale d'alarme, ces moyens électriques étant constitués au moins en partie par un fil spiralé dont le pourcentage d'allongement après étirement complet est compris entre 0 et 50%, et par un enrouleur conforme aux caractéristiques précédentes.The invention thus relates to an assembly consisting of an anti-theft protection device for a presentation article, electrical means connecting the device to an alarm center, these electrical means being constituted at least in part by a spiral wire whose percentage of elongation after complete stretching is between 0 and 50%, and by a retractor according to the preceding characteristics.

L'invention sera mieux comprise et d'autres buts, avantages et caractéristiques de celle-ci, apparaîtront plus clairement à la lecture de la description qui suit de modes non limitatifs de réalisation de l'invention, et qui est faite au regard des dessins annexés sur lesquels :

  • la figure 1 est une vue en plan de l'enrouleur selon l'invention,
    • la figure 2 est une vue de côté de l'enrouleur de la figure 1,
    • la figure 3 est une vue en plan de l'enrouleur de la figure 1 avec un arraché,
    • lafigure 4 est une vue identique à la figure 3, montrant un fil spiralé enroulé,
    • et la figure 5 est une vue en perspective d'un support pour article à protéger, associé à un enrouleur selon l'invention.
The invention will be better understood and other objects, advantages and characteristics thereof, will appear more clearly on reading the following description of non-limiting embodiments of the invention, and which is made with reference to the drawings. annexed in which:
  • FIG. 1 is a plan view of the winder according to the invention,
    • FIG. 2 is a side view of the winder of FIG. 1,
    • FIG. 3 is a plan view of the winder of FIG. 1 with a snatch,
    • FIG. 4 is a view identical to FIG. 3, showing a coiled spiral wire,
    • and FIG. 5 is a perspective view of a support for article to be protected, associated with a reel according to the invention.

Les éléments communs aux différentes figures seront désignés par les mêmes références.The elements common to the different figures will be designated by the same references.

Comme le montrent les figures 1 à 4, l'enrouleur comporte deux supports 1 et 2.As shown in Figures 1 to 4, the winder comprises two supports 1 and 2.

Ces deux supports sont écartés l'un de l'autre, un espace est donc ménagé entre les deux supports. C'est dans cet espace que le fil spiralé pourra être enroulé.These two supports are spaced from one another, a space is formed between the two supports. It is in this space that the spiral wire can be rolled up.

Entre les deux supports 1 et 2, sont disposés deux éléments de guidage 3 et 4, qui sontfixés aux supports par des moyens appropriés. Les supports permettent de maintenir le fil sur les éléments de guidage.Between the two supports 1 and 2 are arranged two guide elements 3 and 4, which are attached to the supports by appropriate means. The supports make it possible to hold the wire on the guiding elements.

Sur l'exemple illustré par les figures, les deux supports de l'enrouleur sont plans et présentent une forme sensiblement rectangulaire. L'enrouleur n'est cependant pas limité à cette forme de réalisation. Il suffit que les deux supports ménagent un espace, dans lequel au moins un élément de guidage du fil spiralé peut être placé, cet espace étant également suffisant pour permettre le stockage du fil spiralé.In the example illustrated by the figures, the two supports of the winder are planar and have a substantially rectangular shape. The reel is however not limited to this embodiment. It is sufficient that the two supports provide a space, in which at least one guiding element of the spiral wire can be placed, this space also being sufficient to allow the storage of the spiral wire.

Les éléments du guidage 3 et 4 qui sont illustrés peuvent prendre la forme de pistes circulaires fixes.The guide elements 3 and 4 which are illustrated may take the form of fixed circular tracks.

Comme l'illustrent les figures 3 et 4, les éléments de guidage sont de préférence espacés l'un de l'autre, ce qui permet de mieux utiliser l'espace ménagé entre les deux supports 1 et 2.As illustrated in Figures 3 and 4, the guide elements are preferably spaced apart from each other, which allows better use of the space between the two supports 1 and 2.

Le fonctionnement de l'enrouleur va être décrit en référence à la figure 4.The operation of the winder will be described with reference to FIG. 4.

Cette figure montre un enrouleur associé à un fil torsadé ou spiralé 10.This figure shows a winder associated with a twisted or spiral wire 10.

Ce fil présente une propriété particulière, Il a la capacité de reprendre, dans une certaine proportion, sa longueur initiale après un étirement complet, puis suppression de l'étirement ou relâchement. Cette capacité est déterminé par le pourcentage d'allongement du fil spiralé, par rapport à sa longueur initiale, après étirement complet ou pratiquement complet, puis suppression de l'étirement. On peut donc qualifier cet allongement de « résiduel ».This thread presents a particular property, It has the capacity to resume, in a certain proportion, its initial length after a complete stretching, then suppression of the stretching or loosening. This capacity is determined by the percentage of elongation of the spiral wire, relative to its initial length, after complete or nearly complete stretching, and then removal of the stretch. We can therefore qualify this elongation as "residual".

Le fil utilisé sur l'enrouleur présente un pourcentage d'allongement après étirement complet qui est compris entre 9 et 50% et, de préférence, entre 0 et 10%.The yarn used on the reel has an elongation percentage after complete stretch which is between 9 and 50% and preferably between 0 and 10%.

Ainsi, par rapport à des fils spiralées classiques tels que les flis utilisés sur les postes téléphoniques, ce fil a la propriété de mieux reprendre sa longueur initiale après un étirement quelconque, puis relâchement. Cette capacité est également communément appelée «effet mémoireThus, compared with conventional spiral threads such as the flis used on telephone sets, this wire has the property to better resume its original length after any stretch, then relaxation. This ability is also commonly referred to as "memory effect

A titre d'exemple de tels fils spiralés, on peut citer un fil commercialisé par la société MR INDUSTRIES, notamment sous la référence 18840. L'allongement résiduel d'un tel fil spiralé, après étirement complet, est de l'ordre de 5%.By way of example of such spiral wires, mention may be made of a wire marketed by MR INDUSTRIES, in particular under the reference 18840. The residual elongation of such a spiral wire, after complete stretching, is of the order of 5 %.

Sur l'exemple Illustré à la figure 4, une extrémité 11 du fil 10 est introdulte dans un orifice 6, pratiqué sur le support 2.In the example shown in FIG. 4, one end 11 of the wire 10 is introduced into an orifice 6 made on the support 2.

Du fait de la présence de spirales, l'extrémité 11 du fil se trouve ainsi bloquée sur le support 2.Due to the presence of spirals, the end 11 of the wire is thus blocked on the support 2.

D'autres moyens de fixation de l'extrémité II du fil pourraient également être prévus.Other means of fixing the end II of the wire could also be provided.

Lorsque l'enrouleur est utilisé avec un dispositif de protection anti-vol, l'extrémité 11 du fil est reliée à une centrale d'alarme, non représentée sur les figures:When the retractor is used with an anti-theft protection device, the end 11 of the wire is connected to an alarm center, not shown in the figures:

Entre ses deux extrémités 11 et 12, le fil spiralé 10 est enroulé sur les moyens de guidage 4 et 5, comme cela est par exemple illustré sur la figure 4.Between its two ends 11 and 12, the spiral wire 10 is wound on the guide means 4 and 5, as shown for example in FIG. 4.

L'extrémité libre 12 du fil passe, de préférence, dans une ouverture 7, ménagée sur le support 1.The free end 12 of the wire passes, preferably, in an opening 7, formed on the support 1.

Sur l'exemple illustré sur les figures, l'ouverture 7 est de forme circulaire et elle est disposée sensiblement au centre du support 1.In the example illustrated in the figures, the opening 7 is circular in shape and is disposed substantially in the center of the support 1.

L'invention n'est cependant pas limitée à cette forme de réalisation.The invention is however not limited to this embodiment.

L'extrémité 12 du fil est, quant à elle, reliée au dispositif de protection anti-vol. Ce dernier est fixé, par des moyens appropriés, sur l'objet à protégerThe end 12 of the wire is, in turn, connected to the anti-theft protection device. The latter is fixed, by appropriate means, on the object to be protected

Ainsi, lorsqu'un utilisateur souhaite prendre en main l'article protégé, il tire sur le fil 10. Ceci provoque l'allongement et le déroulement du fil torsadé 10.Thus, when a user wishes to take charge of the protected article, he pulls on the wire 10. This causes the elongation and unwinding of the twisted wire 10.

Lorsque le consommateur ne tire plus sur le fil, celui-ci reprend, au moins en partie, sa longueur initiale et vient s'enrouler sur les éléments de guidage 4 et 5.When the consumer no longer pulls on the wire, it resumes, at least in part, its initial length and is wound on the guide elements 4 and 5.

L'enroulement du fil sera d'autant plus efficace que l'allongement résiduel du fil torsadé est faible.The winding of the wire will be all the more effective as the residual elongation of the twisted wire is low.

Ainsi, l'enrouleur permet d'assurer, en permanence, une connexion électrique entre le dispositif de protection anti-vol fixé sur-l'article à protéger et la centrale d'alarme, sans que la présence de contacts électriques en rotation soit nécessaire.Thus, the retractor makes it possible to ensure, permanently, an electrical connection between the anti-theft protection device fixed on the article to be protected and the alarm center, without the presence of rotating electrical contacts being necessary. .

La fabrication de l'enrouleur est par ailleurs simple et peu coûteuse puisqu'elle nécessite l'assemblage de pièces mécaniques qui sont de conception simple.The manufacture of the reel is also simple and inexpensive since it requires assembly mechanical parts that are simple in design.

L'ensemble constitué par l'enrouleur selon l'invention et un fil torsadé présentant un allongement résiduel compris entre 0 et 50% et notamment entre 0 et 10%, permet d'assurer un enroulement satisfaisant du fil. Ainsi, sur les meubles servant de présentoir aux articles de démonstration, Il est possible de supprimer tout fil apparentThe assembly constituted by the winder according to the invention and a twisted wire having a residual elongation of between 0 and 50% and in particular between 0 and 10%, makes it possible to ensure a satisfactory winding of the wire. Thus, on the furniture serving as a display for the demonstration articles, It is possible to remove any apparent thread

On se réfère maintenant à la figure 5 qui Illustre un support pour un article de présentation.Referring now to Figure 5 which illustrates a support for a presentation article.

La figure 5 montre un support 20, notamment destiné à un téléphone portable. Ce support comporte un socle plan 21 qui est destiné à être placé sur un meuble servant de présentoir.Figure 5 shows a support 20, in particular for a mobile phone. This support comprises a flat base 21 which is intended to be placed on a piece of furniture serving as a display.

Le support 20 comporte également une paroi arrière 22 qui est, de préférence, légèrement Inclinée par rapport au socle 21.The support 20 also has a rear wall 22 which is preferably slightly inclined relative to the base 21.

Le support 21 comporte des éléments 23 concaves, destinés à recevoir l'objet à protéger, cet objet reposant également sur la paroi arrière 22 du support 20.The support 21 comprises concave elements 23 intended to receive the object to be protected, this object also resting on the rear wall 22 of the support 20.

Sur la face extérieure de la paroi 22, est fixé un enrouleur 24.On the outer face of the wall 22, is fixed a winder 24.

Laforme compacte de cet enrouleur permet de l'intégrer facilement au support 20. Il n'est alors plus nécessaire de fixer l'enrouleur sur le meuble servant de présentoir.The compact form of this reel makes it easy to integrate it into the support 20. It is no longer necessary to fix the reel on the display unit.

En utilisation, l'extrémité libre 12 du fil spiralé de l'enrouleur 24 est reliée à un dispositif de protection anti-vol qui, lui-même, est fixé sur l'article à protéger (non représentés sur la figure).In use, the free end 12 of the spiral wire of the winder 24 is connected to an anti-theft protection device which itself is fixed on the article to be protected (not shown in the figure).

L'autre extrémité 11 du fil spiralé est bloquée sur le support 2 de l'enrouleur 24. Elle est par ailleurs reliée à la centrale d'alarme (non illustrée sur la figure 5).The other end 11 of the spiral wire is blocked on the support 2 of the reel 24. It is also connected to the alarm center (not shown in Figure 5).

Lorsqu'un acheteur potentiel retire l'objet protégé du support 5, le fil spiralé se déroule et passe par l'ouverture 7, ménagée dans le support 1 de l'enrouleur.When a potential buyer removes the protected object from the support 5, the spiral wire unwinds and passes through the opening 7, formed in the support 1 of the winder.

Lorsque l'objet est replacé dans le support 20, le fil spiralé reprend sensiblement sa forme initiale et vient s'enrouler automatiquement dans l'enrouleur 24.When the object is replaced in the support 20, the spiral wire substantially returns to its original shape and is wound automatically in the reel 24.

Aucune longueur résiduelle du fil n'est donc visible sur le support lorsque l'article est en place sur celul-cl.No residual length of the wire is visible on the support when the article is in place on celul-cl.

D'autres formes de support pourraient bien sûr être envisagées, en fonction des dimensions de l'article à protégerOther forms of support could of course be envisaged, depending on the dimensions of the article to be protected

Par ailleurs, l'enrouleur peut trouver d'autres applications, notamment pour les dispositifs anti-vols constitués d'une boucle de fil électrique et qui sont particulièrement destinés aux vêtements placés sur des cintres et suspendus.Furthermore, the retractor can find other applications, including anti-theft devices consisting of a loop of electric wire and which are particularly intended for clothes placed on hangers and hanging.

Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications, ont pour seul but de faciliter la compréhension de ces dernières et ne sauraient en limiter la portée.The reference signs inserted after the technical features mentioned in the claims, are intended only to facilitate the understanding of the latter and can not limit its scope.
