La présente invention concerne un système de verrouillage destiné à empêcher le vol à l'étalage d'articles ou à interdire le retrait d'un article d'un boîtier le contenant, pour des articles tels que des cassettes, vidéocassettes, compacts disques, CD-ROM, lunettes, bouteilles, flaconnages, etc. On connaît dans l'état de la technique plusieurs solutions, en particulier un système de verrouillage décrit dans le brevet français FR2678907. Le dispositif décrit dans ce brevet offre généralement satisfaction. Le but de l'invention est de simplifier encore la réalisation en réduisant le nombre de pièces, et en leur donnant un profil permettant de réduire le coût du moulage et de l'assemblage. Un autre but est de renforcer encore l'efficacité du système contre les tentatives de violation, en améliorant la résistance mécanique. A cet effet, l'invention concerne plus particulièrement un système de verrouillage du type comportant une partie fixe solidaire d'un boîtier présentant une fente d'introduction de l'article à protéger et une partie mobile munie d'une butée propre à obturer partiellement la fente d'introduction en position verrouillée. Le système comporte en outre des moyens propres à empêcher le déplacement de la partie mobile sans un outil spécifique. La partie fixe présente un guide arrière s'étendant selon une direction sensiblement longitudinale. En avant de ce guide, une protubérance présente une lumière comportant un segment arrière sensiblement longitudinal prolongé par un segment incliné s'étendant jusqu'au bord supérieur. La partie mobile est constituée par une pièce creuse comportant à proximité de son extrémité frontale arrière une paroi transversale percée par une fente. Cette fente présente une section complémentaire à la section du guide prévue sur la partie fixe. Dans sa partie médiane, la partie mobile comporte une tige saillante transversale propre à coopérer avec la lumière de la partie fixe de manière à assurer le guidage de la partie mobile suivant un mouvement d'abord longitudinal, puis oblique.The present invention relates to a locking system intended to prevent shoplifting of articles or to prohibit the removal of an article from a case containing it, for articles such as cassettes, videocassettes, compact discs, CDs -ROM, glasses, bottles, bottles, etc. Several solutions are known in the state of the art, in particular a locking system described in French patent FR2678907. The device described in this patent generally offers satisfaction. The object of the invention is to further simplify the production by reducing the number of parts, and by giving them a profile making it possible to reduce the cost of molding and assembly. Another aim is to further strengthen the effectiveness of the system against attempted breaches, by improving mechanical strength. To this end, the invention relates more particularly to a locking system of the type comprising a fixed part integral with a housing having a slot for introducing the article to be protected and a movable part provided with a stop capable of partially closing off. the insertion slot in the locked position. The system also comprises means suitable for preventing the displacement of the mobile part without a specific tool. The fixed part has a rear guide extending in a substantially longitudinal direction. In front of this guide, a protuberance has a lumen comprising a substantially longitudinal rear segment extended by an inclined segment extending to the upper edge. The movable part is constituted by a hollow part comprising, near its rear front end, a transverse wall pierced by a slot. This slot has a section complementary to the section of the guide provided on the fixed part. In its middle part, the mobile part comprises a transverse projecting rod capable of cooperating with the lumen of the fixed part so as to guide the mobile part in a movement that is first longitudinal, then oblique.
Avantageusement, le système de verrouillage selon 1 ' invention comporte une lame longeant la paroi supérieure de la partie mobile selon une direction sensiblement longitudinale dont l'une des extrémités est solidaire de la partie arrière de la partie mobile et dont la partie avant est libre, et s'étend, au repos en position de verrouillage, contre une butée prévue sur la protubérance de la partie fixe. selon un mode de réalisation préféré, l'extrémité libre de ladite lame est coupante. Cette caractéristique vise à éviter le déverrouillage inopiné lorsqu'un choc violent fait entrer en vibration la lame.Advantageously, the locking system according to the invention comprises a blade running along the upper wall of the mobile part in a substantially longitudinal direction, one of the ends of which is integral with the rear part of the mobile part and whose front part is free, and extends, at rest in the locked position, against a stop provided on the protuberance of the fixed part. according to a preferred embodiment, the free end of said blade is cutting. This characteristic is intended to avoid unexpected unlocking when a violent impact causes the blade to vibrate.
Selon une autre variante avantageuse, le système comporte un ressort prenant appui d'une part sur la partie fixe et d'autre part sur la partie mobile, de manière à faciliter le déplacement de l'organe mobile après déverrouillage.According to another advantageous variant, the system comprises a spring bearing on the one hand on the fixed part and on the other hand on the mobile part, so as to facilitate the movement of the mobile member after unlocking.
Selon un exemple de réalisation avantageux, le ressort est logé dans une lumière inclinée prévue à l'avant de la protubérance de la partie fixe.According to an advantageous embodiment, the spring is housed in an inclined opening provided at the front of the protuberance of the fixed part.
Selon une autre variante de réalisation, la protubérance de la partie fixe présente un prolongement formant saillie par rapport à la face avant et venant coopérer, en position de verrouillage, avec un logement prévu à cet effet dans la face avant de la partie mobile.According to another alternative embodiment, the protuberance of the fixed part has an extension projecting from the front face and coming to cooperate, in the locked position, with a housing provided for this purpose in the front face of the mobile part.
La présente invention sera mieux comprise à la lecture de la description qui suit, s'appuyant sur les dessins où : - la figure 1 représente une vue en coupe longitudinale du système de verrouillage en position fermée; la figure 2 représente une vue en perspective de la partie fixe ;The present invention will be better understood on reading the description which follows, based on the drawings in which: - Figure 1 shows a longitudinal sectional view of the locking system in the closed position; Figure 2 shows a perspective view of the fixed part;
- la figure 3 représente une vue en coupe longitudinale du système de verrouillage en position ouverte.- Figure 3 shows a longitudinal sectional view of the locking system in the open position.
La figure 1 représente une vue en coupe longitudinale du dispositif en position fermée.Figure 1 shows a longitudinal sectional view of the device in the closed position.
Il comporte une partie fixe (1) solidaire du boîtier et une partie mobile (2) . Cette partie constituant le prolongement du boîtier est obtenue par moulage du boîtier, non représenté sur la figure. Elle présente à sa partie arrière un guide (3) s'étendant selon un axe longitudinal par rapport à une protubérance arrière (4) perpendiculaire à la face du boîtier. Sa partie arrière présente une pente (24) inclinée de façon à ce que l'énergie d'un choc à cet endroit soit dispersée dans la partie mobile, et ne soit pas transmise longitudinalement à ses composantes, ce qui pourrait dans des cas extrêmes provoquer des fissures.It comprises a fixed part (1) integral with the housing and a mobile part (2). This part constituting the extension of the housing is obtained by molding the housing, not shown in the figure. It has at its rear part a guide (3) extending along a longitudinal axis with respect to a rear protuberance (4) perpendicular to the face of the housing. Its rear part has a slope (24) inclined so that the energy of an impact at this location is dispersed in the mobile part, and is not transmitted longitudinally to its components, which could in extreme cases cause cracks.
La partie fixe (2), représentée en figure 2, en vue en perspective, présente une autre protubérance (5) située en avant de ce guide (3) . Cette protubérance (5) présente une lumière (6) inclinée vers l'avant et s 'ouvrant sur le bord supérieur (7) de la protubérance (5) .The fixed part (2), shown in Figure 2, in perspective view, has another protuberance (5) located in front of this guide (3). This protuberance (5) has a lumen (6) inclined forward and opening on the upper edge (7) of the protuberance (5).
Cette lumière (6) est coudée et présente un segment arrière (8) sensiblement longitudinal prolongé par un segment (9) s'étendant dans une direction générale inclinée vers l'avant, jusqu'au bord supérieur (7) de la protubérance (5) . Un béquet (20) deformable élastiquement obture partiellement l'entrée de cette lumière (6). Elle permet le passage en force de la tige (20) lors de l'assemblage de la partie mobile, et interdit le retrait après assemblage.This light (6) is bent and has a rear segment (8) substantially longitudinal extended by a segment (9) extending in a general direction inclined forward, to the upper edge (7) of the protuberance (5 ). An elastically deformable spoiler (20) partially blocks the entrance to this light (6). It allows the passage of the rod (20) by force during assembly of the mobile part, and prohibits removal after assembly.
La protubérance (5) présente également à sa partie avant une lumière (10) inclinée vers l'avant, s 'ouvrant au niveau de la face frontale avant {12) . Un ressort (14) est logé dans cette lumière (10) .The protuberance (5) also has at its front part a lumen (10) inclined towards the front, opening at the front end face (12). A spring (14) is housed in this light (10).
La protubérance (5) présente encore sur sa face frontale avant un prolongement (13) s'étendant sensiblement longitudinalement. La partie mobile (2) est constituée par une pièce dont la section transversale forme un "U" inversé.The protuberance (5) also has on its front face an extension (13) extending substantially longitudinally. The movable part (2) consists of a part whose cross section forms an inverted "U".
Elle présente une face supérieure (15) , des faces latérales sensiblement rectangulaires et une face frontale avant (16) prolongée par une butée (17) . Elle comporte en outre une cloison transversale (18) placée à proximité de l'extrémité arrière, et une tige transversales (19) en position médiane. La cloison transversale (18) est percée par un trou (21) de section rectangulaire pour le passage du guide (3) . Une lame (22) est disposée à proximité de la face supérieure.It has an upper face (15), substantially rectangular side faces and a front end face (16) extended by a stop (17). It further comprises a transverse partition (18) placed near the rear end, and a transverse rod (19) in the middle position. The transverse partition (18) is pierced by a hole (21) of rectangular section for the passage of the guide (3). A blade (22) is arranged near the upper face.
En position verrouillée représentée en figureIn the locked position shown in the figure
1, cette lame s 'appuie par son extrémité arrière contre une butée prévue à la surface intérieure de la paroi supérieure (15) , par exemple contre la cloison transversale (18) , et à sa partie avant contre une butée (23) prolongeant la surface supérieure de la protubérance (5) . La lame (22) empêche le déplacement relatif des parties mobile (2) et fixe (1), alors que le segment longitudinal (8) de la lumière (6) et le guide (3) empêchent le déplacement vertical de la partie mobile (2) .1, this blade sits at its rear end against a stop provided on the inner surface of the upper wall (15), for example against the transverse partition (18), and at its front part against a stop (23) extending the upper surface of the protuberance (5). The blade (22) prevents the relative displacement of the movable (2) and fixed (1) parts, while the longitudinal segment (8) of the lumen (6) and the guide (3) prevent the vertical displacement of the movable part ( 2).
Il est donc impossible d'écarter la butée (17) de l'ouverture du boîtier. Le prolongement (13) vient par ailleurs se loger dans une cavité complémentaire de la face frontale avant de la pièce mobile (2) pour empêcher la formation d'un bras de levier en cas de tentative de violation du dispositif.It is therefore impossible to separate the stop (17) from the opening of the housing. The extension (13) is also housed in a cavity complementary to the front end face of the moving part (2) to prevent the formation of a lever arm in the event of an attempted violation of the device.
Lorsque 1 'on approche un aimant de la face supérieure (15) de la partie mobile (2), la lame est attirée vers celle-ci, et libère le passage au niveau de la butée (23) . Il devient alors possible de déplacer longitudinalement la partie mobile (2) jusqu'à la position de déverrouillage représentée en figure 3. Lorsque la tige transversale (20) vient au niveau du segment incliné (9) , il guide le mouvement de la partie mobile (2) en un mouvement de pivotement par rapport à l'orifice (21), ce qui assure le déplacement de la partie avant, et notamment de la butée (17) en direction perpendiculaire de l'axe longitudinal. La butée (17) libère alors la fente du boîtier.When one approaches a magnet to the upper face (15) of the movable part (2), the blade is attracted towards the latter, and frees the passage at the level of the stop (23). It then becomes possible to move the mobile part (2) longitudinally to the unlocking position shown in FIG. 3. When the transverse rod (20) comes to the level of the inclined segment (9), it guides the movement of the mobile part (2) in a pivoting movement relative to the orifice (21), which ensures the displacement of the front part, and in particular of the stop (17) in the perpendicular direction of the longitudinal axis. The stop (17) then releases the slot in the housing.
Afin d'éviter un déverrouillage intempestif, la lame présente une tranche avant affûtée ou pointue. En cas de choc violent, elle vient en force contre la butée (23) et le caractère affûté ou pointu de l'extrémité avant empêche le glissement contre la surface arrière de cette butée.To avoid accidental unlocking, the blade has a sharp or pointed front edge. In the event of a violent impact, it comes into force against the stop (23) and the sharp or pointed nature of the front end prevents sliding against the rear surface of this stop.
La partie mobile (2) peut être clipsée simplement sur la partie fixe (1) au moment de l'assemblage, ce qui réduit le coût de fabrication. Le béquet (20) interdit le démontage inopiné du système.The movable part (2) can be simply clipped onto the fixed part (1) at the time of assembly, which reduces the manufacturing cost. The spoiler (20) prohibits unexpected disassembly of the system.
Il est bien entendu que la présente invention peut être réalisée sous de nombreuses variantes équivalentes sans pour autant sortir du champ de la protection. It is understood that the present invention can be implemented in many equivalent variants without departing from the scope of protection.
