Abstract

The theft-prevention equipment is in two parts, the first (1) forming a base-plate on which the housing is placed. It has transverse end faces(4,7), the first of which has a pointer(6) coupled to a mechanical device on the second part(2) which forms the cover immobilising the housing, while the opposite end of the base is U-shaped. The cover has a rectangular extension(13) on one of its larger side surfaces, whose length is greater than its width. The extension has a central oblong groove (16), and a circular hole near its free edge. The baseplate has on the outside a kite-tail-shaped mounting (17) in which the extension is inserted. A boss (18) on the baseplate fits in the groove, limiting cover movement. A hat-shaped protrusion (19) fitting in the hole (15) in the extension keeps the cover stable when fully extended.

Description

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

La présente invention, comme indiqué dans l'énoncé du présent mémoire descriptif, concerne un protecteur perfectionné pour cassettes, conçu pour empêcher le vol de ces articles par des délinquants, lorsqu'ils sont exposés au public dans des locaux de vente.The present invention, as indicated in the description of the present specification, relates to an improved cassette protector, designed to prevent the theft of these articles by delinquents, when they are exposed to the public in sales premises.

Le protecteur constitue ce qui peut être considéré comme une carcasse dans laquelle se loge la cassette, retenue à l'intérieur, rendant son extraction impossible si le couvercle de fermeture qui la retient dans la carcasse n'est pas libéré à l'aide d'un élément spécial. En outre, le protecteur est doté d'un circuit capable de déclencher une alarme lorsqu'il traverse un champ électromagnétique.The protector constitutes what can be considered as a carcass in which the cassette, retained inside, is housed, making its extraction impossible if the closing cover which retains it in the carcass is not released using a special item. In addition, the protector has a circuit capable of raising an alarm when it crosses an electromagnetic field.

ANTECEDENTS DE L'INVENTIONBACKGROUND OF THE INVENTION

Comme état de la technique, on peut citer le modèle d'utilité U-9000683 du même demandeur, modèle revendiquant un protecteur dont la structure, comme il sera possible de le constater dans la présente description, coïncide avec celle du modèle objet de la demande présentée, à l'exception que ce dernier offre une série de particularités et d'améliorations par rapport au précédent, en faisant un modèle présentant de grands avantages.As state of the art, mention may be made of utility model U-9000683 of the same applicant, a model claiming a protector whose structure, as will be seen in the present description, coincides with that of the model which is the subject of the application. presented, except that the latter offers a series of features and improvements over the previous one, making a model with great advantages.

Ainsi, le protecteur objet du modèle U-9000683 était conçu à partir d'une plaque de matériel plastique résistant, de préférence en polycarbonate transparent, plaque dont le contour rectangulaire coïncide avec celui que présentent les carcasses de cassettes conventionnelles, avec la particularité que cette plaque présente, sur un des plans latéraux correspondant à la plus petite longueur, un pan orthogonal, dont la largeur correspond également à l'épaisseur d'une carcasse de cassette. De la même manière, l'autre extrémité présente un pan parallèle à celui qui vient d'être mentionné, et qui se prolonge en un autre pan parallèle à la plaque de base, de façon qu'il forme à cette dernière extrémité un profil en "U", avec un de ses côtés fermé par une cloison.Thus, the object protector of model U-9000683 was designed from a plate of resistant plastic material, preferably transparent polycarbonate, a plate whose rectangular outline coincides with that presented by conventional cassette carcasses, with the particularity that this plate has, on one of the lateral planes corresponding to the shortest length, an orthogonal section, the width of which also corresponds to the thickness of a cassette carcass. In the same way, the other end has a section parallel to the one just mentioned, and which extends into another section parallel to the base plate, so that it forms at this last end a profile in "U", with one of its sides closed by a partition.

De cette manière, la carcasse de la cassette est introduite dans le protecteur. Elle se trouve alors logée dans le boîtier que constitue ce profile en "U", fermé à une de ses extrémités, tandis que le plan opposé est doté d'un pointeau qui sort à l'extérieur, et perpendiculairement insérable dans un dispositif mécanique constitué d'une pièce servant de couvercle. Cette dernière est un boîtier en forme de prisme rectangulaire, qui s'adapte à l'extrémité précisément pourvue du pointeau, permettant ainsi de retenir la carcasse de la cassette.In this way, the casing of the cassette is introduced into the protector. It is then housed in the housing that constitutes this "U" profile, closed at one of its ends, while the opposite plane is provided with a needle which projects outside, and perpendicularly insertable into a mechanical device constituted a piece serving as a cover. The latter is a rectangular prism-shaped housing, which adapts to the end precisely provided with the needle, thus making it possible to retain the casing of the cassette.

Ce pointeau insérable dans le dispositif mécanique empêche que le couvercle mentionné ne puisse se détacher, à moins que l'on fasse usage d'un outil approprié pour y parvenir. C'est évidemment cet outil que possédera le propriétaire ou employé du magasin de vente de l'Article.This insertable pin in the mechanical device prevents the mentioned cover from being able to come off, unless an appropriate tool is used to achieve this. It is obviously this tool that the owner or employee of the store selling the Item will have.

En outre, la plaque qui constitue le protecteur ou la carcasse de la bande elle-même, est dotée d'un circuit électronique qui réagit et déclenche une alarme lorsqu'il traverse un champ électromagnétique, trahissant logiquement le délinquant qui s'apprête à soustraire l'article ou la cassette. C'est-à-dire, le dégagement de la cassette de son protecteur exige l'intervention de l'employé ou du propriétaire de l'établissement, car dans le cas contraire, et avant qu'elle ne puisse être dégagée, l'alarme se déclencherait comme cela a été dit précédemment.In addition, the plate which constitutes the protector or the carcass of the tape itself, has an electronic circuit which reacts and sets off an alarm when it crosses an electromagnetic field, logically betraying the offender who is about to take the article or the cassette. That is to say, the release of the tape from its protector requires the intervention of the employee or the owner of the establishment, because otherwise, and before it can be released, the alarm would be triggered as previously stated.

Donc, ce protecteur revendiqué dans le modèle d'utilité U-9000683 remplit avec efficacité sa fonction, constituant un élément simple et économique.Therefore, this protector claimed in the utility model U-9000683 effectively fulfills its function, constituting a simple and economical element.

Or, le protecteur ici mentionné présente un léger inconvénient: lorsqu'on le manipule pour désolidariser le couvercle du reste du protecteur, c'est-à-dire la plaque sur laquelle se trouve la carcasse de la bande, les deux pièces sont alors totalement détachées l'une de l'autre, de façon que, d'une part, le pointeau se trouve à nu à l'extérieur, risquant de provoquer des lésions (égratignures, clouage, etc.) chez les manipulateurs, et si à cela nous ajoutons le fait que ce pointeau, du fait de son petit diamètre et de son orientation vers l'extérieur, peut se casser, rendant le protecteur inutilisable, il est évident que, malgré l'efficacité du protecteur en question, ce dernier présente cette carence ou inconvénient.However, the protector mentioned here has a slight drawback: when it is manipulated to separate the cover from the rest of the protector, that is to say the plate on which the carcass of the strip is located, the two parts are then completely detached from each other, so that, on the one hand, the needle is exposed outside, risking causing injuries (scratches, nailing, etc.) in the manipulators, and if this we add the fact that this needle, because of its small diameter and its orientation towards outside, can break, making the protector unusable, it is obvious that, in spite of the effectiveness of the protector in question, this latter presents this deficiency or inconvenience.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Le protecteur de l'invention est basé sur le modèle précédemment décrit, présentant la même configuration mais une amélioration permettant de résoudre le problème mentionné.The protector of the invention is based on the previously described model, having the same configuration but an improvement making it possible to solve the mentioned problem.

En effet, le protecteur de l'invention présente la particularité que l'une des deux plans verticaux de plus grande dimension de la pièce constitutive du couvercle du protecteur, se prolonge, sur une section seulement de sa longueur, en une extension plane dont les bords libres sont biselés de façon à pouvoir se loger et glisser sur une entaille en "queue de milan" prévue à cet effet sur le plan extérieur de la plaque constitutive du protecteur. La prolongation plane du couvercle a été conçue avec une rainure longitudinale centrale, ainsi qu'un orifice à proximité de l'extrémité de la rainure, dans laquelle se loge un téton prévu à cet effet sur le plan extérieur du protecteur. Le plan extérieur a été conçu avec un logement dans lequel s'introduit l'extension plane du couvercle mentionné. Quant à l'orifice circulaire, il est susceptible de servir de logement d'un petit pivot ou d'une petite saillie en forme de chapeau sphérique, également prévu sur la face extérieure mentionnée ci-dessus, de façon à assurer la stabilité du couvercle par rapport au protecteur lorsqu'il est en position de retrait maximum de ce dernier.Indeed, the protector of the invention has the particularity that one of the two vertical planes of larger dimension of the component part of the protector cover, extends, over a section only of its length, in a plane extension whose free edges are bevelled so as to be able to lodge and slide over a notch in "Milanese tail" provided for this purpose on the outside of the plate constituting the protector. The planar extension of the cover was designed with a central longitudinal groove, as well as an orifice near the end of the groove, in which is housed a stud provided for this purpose on the outside of the protector. The exterior plan has been designed with a housing into which the planar extension of the mentioned cover is introduced. As for the circular orifice, it is capable of serving as a housing for a small pivot or a small projection in the form of a spherical cap, also provided on the outside face mentioned above, so as to ensure the stability of the cover. relative to the protector when it is in the position of maximum withdrawal of the latter.

Ainsi, la plaque ou le couvercle peut glisser sur la plaque du protecteur pour procéder à sa fermeture et à son ouverture. C'est-à-dire, dans ce dernier cas, pour permettre le retrait ou l'introductlon de la carcasse de la cassette, mais le couvercle ne se désolidarisera jamais de la plaque du protecteur, étant donné que le téton de ce dernier est logé dans la rainure du couvercle, de façon que le pointeau est toujours protégé. En effet, en position d'ouverture, le retrait maximum du couvercle par rapport à la plaque du protecteur correspond à la profondeur du couvercle sur l'axe horizontal, égale à la longueur du pointeau mentionné.Thus, the plate or the cover can slide on the protector plate to close and open it. That is to say, in the latter case, to allow removal or introduction of the casing from the cassette, but the cover will never detach from the guard plate, being given that the nipple of the latter is housed in the groove of the cover, so that the needle is always protected. Indeed, in the open position, the maximum shrinkage of the cover relative to the protector plate corresponds to the depth of the cover on the horizontal axis, equal to the length of the needle punch mentioned.

Bien que le protecteur soit décrit pour un usage appliqué à des cassettes conventionnelles, il peut également s'appliquer à la protection de disques digitaux, c'est-à-dire de "compact disc". Dans ce cas, la seule variation qu'il présente par rapport au protecteur décrit, est une plus grande largeur permettant de loger le "compact disc", plus large que les cassettes conventionnelles.Although the protector is described for a use applied to conventional cassettes, it can also be applied to the protection of digital discs, that is to say of "compact disc". In this case, the only variation that it presents with respect to the protector described, is a greater width making it possible to accommodate the "compact disc", wider than conventional cassettes.

Afin de compléter la description qui suit et d'aider à mieux comprendre les caractéristiques de l'invention, un jeu de plans dont les figures permettront de comprendre plus aisément les innovations et les avantages qu'apporte l'invention, est joint au présent mémoire.In order to complete the description which follows and to help better understand the characteristics of the invention, a set of plans, the figures of which will make it easier to understand the innovations and the advantages which the invention brings, is attached to this memorandum .

DESCRIPTION DE LA FORME DE REALISATION PREFEREEDESCRIPTION OF THE PREFERRED EMBODIMENT

Comme le montre ces figures, le protecteur que l'invention propose est composé de deux pièces (1 et 2), de telle façon que la pièce 1 constitue ce qui peut être considéré comme une plaque de base de positionnement de la carcasse (3) de la cassette, tandis que la pièce (2) constitue un couvercle qui retient cette carcasse (3) à l'intérieur du protecteur formé par les pièces (1) et (2).As these figures show, the protector that the invention proposes is made up of two parts (1 and 2), so that part 1 constitutes what can be considered as a base plate for positioning the carcass (3) of the cassette, while the part (2) constitutes a cover which retains this carcass (3) inside the protector formed by the parts (1) and (2).

La plaque de base (1) est rectangulaire et les dimensions de son contour correspondent avec celles de la carcasse (3) de la cassette. Sur un de ses bords de moindre longueur, cette pièce, ou plaque (1), présente un pan orthogonal (4) qui renferme une espèce de rivet (5) duquel sort un pointeau extérieur (6). La largeur de ce pan (4) correspond à l'épaisseur de la carcasse (3).The base plate (1) is rectangular and the dimensions of its outline correspond to those of the casing (3) of the cassette. On one of its edges of lesser length, this piece, or plate (1), has an orthogonal section (4) which encloses a kind of rivet (5) from which an external needle (6) comes out. The width of this panel (4) corresponds to the thickness of the carcass (3).

Le bord opposé au pan (4), présente un premier pan orthogonal (7), analogue au pan (4) mentionné, qui se prolonge en un pan (8) perpendiculaire au précédent et parallèle à la plaque de base (1), formant un profil en "U" à cette extrémité, l'un des côtés étant fermé par une cloison (9), constituant la limite de pénétration maximum de la carcasse de la cassette (3) lors de son positionnement sur la plaque (1), adaptée à la forme de la cassette. Cette dernière se trouve retenue entre les pans extrêmes, (4) et (7), et la cloison (9), et pour empêcher l'extraction de la cassette le couvercle (2) a été prévu. Ce couvercle est disposé à l'extrémité correspondant au pan (4) et assure l'immobilisation totale de la carcasse de la cassette (3).The edge opposite the pan (4) has a first orthogonal pan (7), similar to the pan (4) mentioned, which extends into a pan (8) perpendicular to the previous one and parallel to the base plate (1), forming a "U" profile at this end, one of the sides being closed by a partition (9), constituting the maximum penetration limit of the carcass of the cassette (3) when it is positioned on the plate (1), adapted to the shape of the cassette. The latter is retained between the end panels, (4) and (7), and the partition (9), and to prevent the extraction of the cassette, the cover (2) has been provided. This cover is arranged at the end corresponding to the pan (4) and ensures total immobilization of the carcass of the cassette (3).

Ce couvercle (2) est de configuration prismatique rectangulaire, de faible profondeur, et dont les dimensions sont telles qu'elles lui permettent de s'adapter à l'extrémité du pan (4) auquel il se trouve contigu, ainsi qu'à la partie correspondante de la carcasse (3) de la cassette, avec la particularité que le plan supérieur de ce couvercle (2) est doté d'une espèce de cloche centrale (10) prévue pour le logement intérieur d'un dispositif mécanique ou préhenseur conventionnel dans lequel peut s'insérer, rester fixé et retenu le pointeau (1), de façon que le couvercle restera en permanence solidaire de la plaque (1), et par conséquent la cassette protégée par le protecteur formé par les deux pièces (1) et (2).This cover (2) is of rectangular prismatic configuration, of shallow depth, and whose dimensions are such that it allows it to adapt to the end of the pan (4) to which it is contiguous, as well as to the corresponding part of the casing (3) of the cassette, with the particularity that the upper plane of this cover (2) is provided with a kind of central bell (10) intended for the interior housing of a conventional mechanical or gripper device in which can be inserted, remain fixed and retained the needle (1), so that the cover will remain permanently secured to the plate (1), and therefore the cassette protected by the protector formed by the two parts (1) and (2).

D'autre part, il a déjà été dit que, soit le protecteur, soit la carcasse de la cassette (3), est doté d'un circuit électronique déterminant d'un moyen capable de faire varier un champ électromagnétique et de déclencher une alarme, indiquant que la personne qui traverse ce champ porte un objet, dans ce cas une carcasse de cassette (3), qui n'est pas passée par la caisse.On the other hand, it has already been said that either the protector or the casing of the cassette (3) is provided with an electronic circuit determining a means capable of varying an electromagnetic field and of triggering an alarm , indicating that the person crossing this field is carrying an object, in this case a cassette casing (3), which has not passed by the cash register.

Pour pouvoir extraire la cassette (3), il suffit de désaccoupler le dispositif mécanique formé par l'élément logé dans la cloche 10 et le pointeau (6) qui le retient, dont la désolidarisation se fait à l'aide d'un dispositif magnétique adéquat, manipulé par l'utilisateur ou employé du magasin de vente, et permettant de séparer les deux pièces, mais non totalement comme indiqué plus loin.To be able to extract the cassette (3), it suffices to decouple the mechanical device formed by the element housed in the bell 10 and the needle (6) which retains it, the detachment of which is effected by means of a magnetic device adequate, handled by the user or employee of the sales store, and allowing the two parts to be separated, but not completely as indicated below.

D'autre part, le protecteur a été conçu de façon à ce que le dispositif conventionnel logé dans la cloche (10) soit retenu par une plaque interne (11) logée et fixée par un adhésif ou tout autre moyen conventionnel, au fond du couvercle (2), comme l'illustrent les figures 2 et 3. Cette plaque (11) retient donc le dispositif préhenseur et possède un orifice (12) permettant le passage du pointeau (6), qui entrera dans le dispositif préhenseur et sera retenu par ce dernier.On the other hand, the protector has been designed so that the conventional device housed in the bell (10) is retained by an internal plate (11) housed and fixed by an adhesive or any other conventional means, at the bottom of the cover. (2), as illustrated in FIGS. 2 and 3. This plate (11) therefore retains the gripping device and has an orifice (12) allowing the needle (6) to pass, which will enter the gripping device and will be retained by this last.

La véritable innovation que présente le protecteur décrit réside dans le couvercle (1) et plus concrètement une de ses faces latérales de plus grande dimension, qui se prolonge en une extension rectangulaire (13) dont les bords libres sont biselés. Cette extension est dotée d'un orifice circulaire (15) à proximité de la bordure (14), et d'une rainure longitudinale (16) centrée sur cette extension (13).The real innovation presented by the protector described resides in the cover (1) and more specifically one of its larger side faces, which extends into a rectangular extension (13) whose free edges are bevelled. This extension has a circular orifice (15) near the edge (14), and a longitudinal groove (16) centered on this extension (13).

Cette extension rectangulaire (13) est prévue pour aller se loger dans un logement complémentaire (17) dans lequel elle glisse, aménagé sur la face extérieure de la plaque (1), logement en forme de "queue de milan" prévu pour recevoir cette extension (13).This rectangular extension (13) is intended to be housed in an additional housing (17) in which it slides, arranged on the outer face of the plate (1), housing in the form of a "milan tail" provided to receive this extension (13).

La surface extérieure ou plan du logement (17) de la plaque (1) du protecteur sont dotés d'un téton (18) et d'un appendice (19) en forme de boulon sphérique, le téton (18) allant se loger dans la rainure (16) de l'extension (13) appartenant au couvercle (2).The outer surface or plan of the housing (17) of the plate (1) of the protector are provided with a stud (18) and an appendage (19) in the form of a spherical bolt, the stud (18) going to be housed in the groove (16) of the extension (13) belonging to the cover (2).

De cette façon, l'extension (13) du couvercle (2) peut glisser dans le logement (17) de la plaque (1) entre certaines limites, déterminées par la longueur de la rainure (16), étant donné que le téton (18) se trouvera en butée contre les extrémités de la rainure (16), se stabilisant dans la position de retrait maximum grâce à l'introduction de l'appendice (19) dans l'orifice (15).In this way, the extension (13) of the cover (2) can slide in the housing (17) of the plate (1) between certain limits, determined by the length of the groove (16), since the stud ( 18) will be in abutment against the ends of the groove (16), stabilizing in the position of maximum withdrawal by the introduction of the appendage (19) into the orifice (15).

De la description précédente découle le fait que le couvercle (2) ne pourra jamais se désolidariser complètement de la plaque de base (1), mais pourra coulisser dans les deux sens et permettre, d'un côté l'introduction de la carcasse de la cassette (3), et de l'autre le déplacement vers l'intérieur pour retenir cette dernière. Ainsi, dans la position de retrait maximum, la bordure périmétrique de l'embouchure correspondant au couvercle (2) correspondra avec le plan du pan (4) pourvu du pointeau (6), de façon que ce dernier se trouvera parfaitement protégé, sans risque de produire des lésions ni qu'il ne se casse, outre le fait que le couvercle et la plaque (1) qui constituent l'ensemble du protecteur sont toujours reliés entre eux.From the preceding description follows the fact that the cover (2) can never be completely detached from the base plate (1), but can slide in both directions and allow, on one side the introduction of the carcass of the cassette (3), and on the other the movement inward to retain the latter. Thus, in the position of maximum withdrawal, the perimeter edge of the mouth corresponding to the cover (2) will correspond with the plane of the pan (4) provided with the needle (6), so that the latter will be perfectly protected, without risk to produce lesions or that it will break, in addition to the fact that the cover and the plate (1) which constitute the whole of the protector are always interconnected.

Enfin, comme cela a déjà été dit précédemment, il convient de signaler que la structure du protecteur mentionné ici peut avoir une autre application et être utilisée comme protecteur de disques digitaux ou "compact disc", le protecteur étant plus large dans ce cas.Finally, as already mentioned above, it should be noted that the structure of the protector mentioned here can have another application and be used as digital disc protector or "compact disc", the protector being wider in this case.
