Description

La présente invention concerne un dispositif mécanique de verrouillage de la porte d'une caisse pouvant contenir des valeurs.The present invention relates to a mechanical door locking device a case that can contain values.

Une caisse est un boítier de construction robuste dont une face comprend une porte verrouillable articulée autour d'une charnière. Le verrouillage de la porte s'effectue au moyen d'une clé tournant dans une serrure fixée sur la face extérieure de la porte. La clé actionne l'axe de la serrure qui est lié à un élément coulissant appelé plaque, situé sur la face interne de la porte. Cette plaque s'emboíte dans un logement en regard de la plaque disposé sur le bord du boítier entourant la porte.A box is a robust construction, one side of which includes a door lockable articulated around a hinge. The door is locked by means of a key turning in a lock fixed on the external face of the door. The key activates the axis of the lock which is linked to a sliding element called plate, located on the inside of the door. This plate fits into a housing opposite the plate disposed on the edge of the housing surrounding the door.

Une telle caisse est utilisée principalement dans le domaine de la téléphonie publique et des automates de vente où des pièces de monnaie sont traitées par un monnayeur et recueillies dans la caisse. Il est néanmoins préciser que la présente invention ne se limite pas à cette application mais concerne également tous types de caisses renforcées telles que coffres.Such a case is used mainly in the field of telephony public and vending machines where coins are processed by a coin and collected in the cash register. It should nevertheless be noted that this invention is not limited to this application but also relates to all types of reinforced boxes such as chests.

L'invention se concentre plus particulièrement sur le mécanisme qui relie la serrure à la ou les plaques. Lors de la fermeture de la porte, la serrure actionne par la rotation de la clé une ou plusieurs plaques qui se déplacent sur des supports fixés sur la porte pour se loger par exemple dans une rainure solidaire au boítier. Le mouvement rotatif de l'axe de la serrure est converti en mouvement de translation de ou des plaques au moyen d'un levier fixé à l'axe de la serrure. Le levier actionne le mouvement des plaques en direction de rainures correspondantes du bord du boítier. Une rotation de la clé dans le sens inverse permet l'ouverture de la porte, les plaques se retirant des rainures par une translation dans le sens opposé à celui de la fermeture.The invention focuses more particularly on the mechanism which connects the lock to the plate (s). When closing the door, the lock actuates by rotation of the key one or more plates which move on supports fixed on the door to be housed for example in a groove integral with the housing. Movement rotary axis of the lock is converted into translational movement of plates by means of a lever fixed to the axis of the lock. The lever operates the movement of the plates in the direction of corresponding grooves from the edge of the housing. Turning the key in the opposite direction will open the door, plates withdrawing from the grooves by translation in the opposite direction to that of closing.

Tous les appareils utilisant des pièces de monnaie comme moyen de paiement tels que les publiphones ou les distributeurs automatiques comportent une caisse où les pièces acceptées sont collectées. Ces appareils étant situés dans la majorité des cas à l'extérieur et sur la voie publique, ils sont exposés à divers actes de vandalisme. Plus particulièrement, la caisse est souvent fracturée et vidée de son contenu de pièces de monnaie. Afin de résister à ces ouvertures frauduleuses, le boítier de la caisse, la porte et son mécanisme de verrouillage sont renforcés et réalisés en matériaux résistants comme des alliages spéciaux à base d'acier.All devices that use coins as payment payphones or vending machines have a cash register where accepted coins are collected. These devices being located in the majority of cases outside and on the public highway, they are exposed to various acts of vandalism. More specifically, the body is often fractured and emptied of its content of coins. In order to resist these fraudulent openings, the body box, the door and its locking mechanism are reinforced and made of resistant materials such as special alloys based on steel.

Malgré cette construction solide, plusieurs cas d'effraction par perçage de la porte ou du boítier de la caisse ont été constatés:

  • Perçage dans le corps de la serrure à côté de l'orifice servant à la clé permet un accès au levier reliant les plaques à l'axe de la serrure afin de le manoeuvrer au moyen d'un tournevis par exemple pour forcer sa rotation.
  • Perçage effectué dans une des faces latérales du boítier à proximité du bord de la porte à la hauteur de la serrure. Le trou ainsi percé permet d'agir sur le levier actionnant les plaques en exerçant une force suffisante sur la goupille de manière à débloquer et faire tourner le levier.
Despite this solid construction, several cases of break-in by drilling the door or the box of the box were noted:
  • Drilling in the body of the lock next to the orifice used for the key allows access to the lever connecting the plates to the axis of the lock in order to operate it using a screwdriver for example to force its rotation.
  • Drilling in one of the side faces of the case near the edge of the door at the height of the lock. The hole thus drilled makes it possible to act on the lever actuating the plates by exerting sufficient force on the pin so as to unlock and rotate the lever.

L'art antérieur fait état d'une réalisation d'un verrouillage de porte de caisse qui comprend une serrure à clé, deux plaques coulissant sur des supports disposés de part et d'autre de la serrure dans un plan parallèle à celui de la porte, un levier appelé came, fixé sur l'axe de la serrure muni d'une goupille à chaque extrémité. Ces goupilles sont engagées dans une glissière formant un orifice allongé dans chacune des plaques. Le levier de forme allongée est comparable à un pont entre les plaques de chaque côté de la serrure dont le milieu est maintenu à l'axe de la serrure au moyen d'un écrou. Les goupilles fixées à chaque extrémité coulissent dans les orifices correspondant de chaque plaque. Ce dispositif de verrouillage connu est illustré ci-après dans les figures.The prior art reports an embodiment of a cash door lock which includes a key lock, two sliding plates on supports arranged on both sides of the lock in a plane parallel to that of the door, a lever called cam, fixed on the axis of the lock provided with a pin at each end. These pins are engaged in a slide forming an elongated hole in each plates. The elongated lever is comparable to a bridge between the plates on each side of the lock, the middle of which is maintained at the axis of the lock at by means of a nut. The pins attached to each end slide in the corresponding holes in each plate. This known locking device is illustrated below in the figures.

La rotation dans un sens de l'axe de la serrure au moyen de la clé entraíne une translation des plaques en direction du bord de la porte pour sa fermeture. Une rotation du même axe dans le sens contraire entraínant une translation des plaques en direction de la serrure pour l'ouverture.The rotation in one direction of the axis of the lock by means of the key causes a translation of the plates towards the edge of the door to close it. A rotation of the same axis in the opposite direction causing a translation of the plates towards the lock for opening.

Dans le cas de cette réalisation, un perçage dans le corps de la serrure ou dans son voisinage immédiat permet l'accès à la came reliant les deux plaques. Il est alors possible d'exercer une force suffisante au moyen d'une barre sur le bord de la came pour la faire tourner. In the case of this embodiment, a bore in the body of the lock or in its immediate vicinity allows access to the cam connecting the two plates. So he is possible to exert sufficient force by means of a bar on the edge of the cam to rotate it.

Un perçage sur un des côtés de la caisse donne accès à la partie de la goupille dépassant de la came avant son engagement dans la glissière correspondante de la plaque. Dans ce cas une force exercée sur la goupille permet aussi de forcer la rotation de la came comme dans le cas précédent, et par conséquent l'axe de la serrure.A hole on one side of the body gives access to the part of the pin protruding from the cam before its engagement in the corresponding slide of the plate. In this case a force exerted on the pin also makes it possible to force the rotation of the cam as in the previous case, and therefore the axis of the lock.

Le document CH401740 décrit un système de fermeture et de verrouillage de la porte d'un coffre-fort. L'ouverture et la fermeture de la porte sont effectués au moyen d'un disque rotatif muni de poignées situé sur la face extérieure de la porte actionnant une plaque de verrouillage par l'intermédiaire d'une came excentrique. Une serrure à clé placée au centre du disque rotatif actionne une plaque d'arrêt munie d'une goupille permettant de bloquer la came excentrique après la fermeture de la porte. Ce système de verrouillage relativement complexe nécessite la manoeuvre de deux éléments respectivement la clé et le disque pour déverrouiller et ouvrir ou fermer et verrouiller la porte.The document CH401740 describes a system for closing and locking the door to a safe. The door is opened and closed by means of a rotating disc with handles located on the outside of the door actuating a locking plate via an eccentric cam. A key lock placed in the center of the rotating disc activates a stop plate fitted with a pin to lock the eccentric cam after closing Door. This relatively complex locking system requires the operation of two elements respectively the key and the disc to unlock and open or close and lock the door.

Le but de la présente invention est de proposer un dispositif simple de verrouillage de la porte d'une caisse dont les éléments ont une structure et une disposition empêchant l'ouverture de la porte notamment après le perçage du boítier ou de la porte de la caisse.The object of the present invention is to provide a simple locking device of a cash register door, the elements of which have a structure and a layout preventing the door from opening, especially after drilling the housing or cash door.

Ce but est atteint par un dispositif mécanique de verrouillage de la porte d'une caisse situé sur la face interne de cette porte comportant une serrure à clé accessible depuis la face extérieure de la porte, une came actionnant au moins une plaque de verrouillage et solidaire à l'axe de la serrure, caractérisé en ce que cette came s'étend généralement parallèlement au plan de la porte à une distance minimale nécessaire au jeu mécanique, ladite came comporte au moins une partie d'entraínement en appui sur le bord de la plaque de verrouillage, cette dernière étant montée sur une pluralité de supports coulissants solidaires à la porte et s'étend soit sur le même plan que la came, soit sur un plan supérieur au plan de ladite came.This object is achieved by a mechanical device for locking the door of a box. located on the inside of this door with an accessible key lock from the outside of the door, a cam actuating at least one plate locking and integral with the axis of the lock, characterized in that this cam generally extends parallel to the plane of the door at a minimum distance necessary for mechanical play, said cam comprises at least one part drive bearing on the edge of the locking plate, the latter being mounted on a plurality of sliding supports integral with the door and extends either on the same plane as the cam, or on a plane greater than the plane of said cam.

Selon une première variante, la came est fixée à l'axe de la serrure parallèlement au plan de la porte. La plaque de verrouillage est montée sur des supports coulissants fixés à la porte, la hauteur de ces derniers permet de maintenir la plaque de verrouillage dans le plan de la came. De plus un ressort relie la plaque de verrouillage à une goupille fixée à la porte par exemple.According to a first variant, the cam is fixed to the axis of the lock parallel to the door plan. The locking plate is mounted on sliding supports fixed to the door, the height of these keeps the plate locking in the plane of the cam. In addition, a spring connects the plate locking with a pin fixed to the door for example.

La rotation de l'axe de la serrure effectuée à l'aide de la clé entraíne une rotation de la came dont la forme lui permet de s'appuyer sur la tranche de la plaque de verrouillage. Une force est ainsi exercée sur la plaque de verrouillage provoquant un mouvement de translation vers les bords du boítier de la caisse assurant le verrouillage de la porte. La plaque de verrouillage est bloquée par la came; dans cette position, le ressort est tendu.The rotation of the axis of the lock made using the key causes a rotation of the cam whose shape allows it to rest on the edge of the plate locking. A force is thus exerted on the locking plate causing a translational movement towards the edges of the body of the box ensuring the door lock. The locking plate is blocked by the cam; in this position, the spring is tensioned.

Une rotation de la came dans le sens inverse débloque la plaque de verrouillage. Elle se dégage des bords du boítier sous lesquels elle était emboítée par un mouvement de translation en direction de la serrure grâce à la traction exercée par le ressort. Ce retrait de la plaque de verrouillage permet l'ouverture de la porte de la caisse.A rotation of the cam in the opposite direction releases the locking plate. It emerges from the edges of the case under which it was fitted by a translational movement towards the lock due to the traction exerted by the spring. This removal of the locking plate allows the door to be opened. checkout.

Selon une seconde variante, la plaque de verrouillage est montée sur des supports coulissants fixés à la porte, la hauteur de ces derniers permet de maintenir la plaque de verrouillage au-dessus de la came en la recouvrant partiellement. Une goupille, fixée à la came et dépassant de la face opposée à celle en regard de la porte, est engagée dans une ouverture allongée dans la plaque de verrouillage. Cette ouverture sert de glissière à la goupille qui peut y coulisser librement.According to a second variant, the locking plate is mounted on supports sliding fixed to the door, the height of these keeps the plate locking above the cam by partially covering it. A pin, attached to the cam and projecting from the face opposite to that opposite the door, is engaged in an elongated opening in the locking plate. This opening serves as a slide for the pin which can slide there freely.

La rotation de l'axe de la serrure effectuée à l'aide de la clé entraíne une rotation de la came dont la goupille engagée dans la plaque de verrouillage entraíne celle-ci dans un mouvement de translation.The rotation of the axis of the lock made using the key causes a rotation of the cam whose pin engaged in the locking plate drives the latter in a translational movement.

Une variante préférée de l'invention s'applique sur une porte d'épaisseur plus faible que la longueur du corps de la serrure. Dans ce cas la came comporte, dans la zone centrale, un capot qui entoure entièrement le corps de la serrure pour le protéger. L'axe de la serrure est fixé par un écrou sur la face supérieure du capot qui est solidaire à la came.A preferred variant of the invention is applied to a door of smaller thickness than the length of the lock body. In this case the cam has, in the area central, a cover which completely surrounds the body of the lock to protect it. The axis of the lock is fixed by a nut on the upper face of the cover which is integral with the cam.

Les avantages de ce dispositif résident dans la protection contre les effractions par perçage de la porte ou du boítier de la caisse. The advantages of this device lie in the protection against break-ins by drilling the door or the box of the box.

Un perçage dans le corps de la serrure aboutit sur la face supérieure du capot dans le voisinage de l'écrou de fixation de la serrure. Un tel trou n'offre aucune prise ni point d'appui susceptible de forcer la rotation de la came dans le but d'ouvrir la porte.A hole in the body of the lock leads to the upper side of the cover in the vicinity of the lock fixing nut. Such a hole offers no grip or fulcrum capable of forcing the rotation of the cam in order to open the door.

Le perçage à travers la porte, à coté de la serrure, aboutit sur la came où une force qui permettrait sa rotation n'est pas applicable, faute de point d'appui, notamment à cause de la faible distance qui sépare la came de la porte.Drilling through the door, next to the lock, ends on the cam where a force which would allow its rotation is not applicable, for lack of a fulcrum, in particular to because of the short distance between the cam and the door.

La forme généralement elliptique ou circulaire de la came ne présente aucun point d'appui à une barre passant par un trou dans la porte comme le ferait les bords de la came de forme polygonale allongée connue de l'art antérieur.The generally elliptical or circular shape of the cam has no points to support a bar passing through a hole in the door as the edges of the cam of elongated polygonal shape known from the prior art.

Le perçage latéral ne donne pas d'accès à la goupille comme dans le cas cité plus haut car cette dernière est protégée par la glissière de la plaque de verrouillage dans laquelle elle est engagée. De plus, la goupille ne dépassant pas de la face supérieure de la plaque de verrouillage, elle reste inaccessible avec un outil tel qu'une barre ou un levier.The lateral drilling does not give access to the pin as in the case cited more high because the latter is protected by the slide of the locking plate in which it is engaged. In addition, the pin does not protrude from the face top of the locking plate, it remains inaccessible with a tool such than a bar or a lever.

Dans le cas où la came et les plaques de verrouillage sont situées dans le même plan, il n'est pas non plus possible d'accéder à la came par un des côtés de la caisse pour y exercer une force car la came est masquée par les plaques de verrouillage.In case the cam and the locking plates are located in the same plan, it is also not possible to access the cam from one of the sides of the body to exert a force there because the cam is masked by the locking plates.

La figure 1 et la figure 2 qui est une coupe selon A-A montrent le dispositif de verrouillage, selon l'art antérieur, monté sur la face interne d'une porte de caisse (1). Ce dispositif comporte deux plaques de verrouillage (4, 4') disposées de chaque côté de la serrure (8) sur des supports coulissants (5, 5') parallèlement au plan de la porte. Une came (2) de forme allongée solidaire à l'axe de la serrure (7) est située dans un plan parallèle au-dessus des plaques de verrouillage (4, 4'). Ces dernières sont (4, 4') munies chacune d'une glissière (9, 9') où est engagée une goupille (3, 3') qui est fixée à chaque extrémité de la came (2). Une rotation de la came (2) provoque un mouvement de translation des plaques de verrouillage (4, 4') engendré par la poussée des goupilles (3, 3') qui coulissent dans leur glissière (9, 9').Figure 1 and Figure 2 which is a section along A-A show the device locking, according to the prior art, mounted on the internal face of a cash door (1). This device comprises two locking plates (4, 4 ') arranged on each side of the lock (8) on sliding supports (5, 5 ') parallel to the plane of the door. An elongated cam (2) integral with the axis of the lock (7) is located in a parallel plane above the locking plates (4, 4 '). These last are (4, 4 ') each provided with a slide (9, 9') where a pin (3, 3 ') is engaged which is fixed to each end of the cam (2). A rotation of the cam (2) causes a translational movement of the locking plates (4, 4 ') generated by the push of the pins (3, 3 ') which slide in their slide (9, 9').

La figure 6 montre une caisse dont la porte (1) est munie du dispositif de verrouillage (10) selon l'invention. La porte (1) comporte une charnière (13) le long du côté inférieur. Lors du verrouillage, les plaques (4, 4') se trouvant à gauche et à droite de la serrure s'écartent de manière à dépasser des trois autres côtés de la porte (1) pour venir se loger dans des rainures correspondantes situées dans les bords (14) de l'ouverture du boítier (11).Figure 6 shows a box whose door (1) is fitted with the locking device (10) according to the invention. The door (1) has a hinge (13) along the side inferior. When locking, the plates (4, 4 ') located to the left and right of the lock deviates so as to project from the other three sides of the door (1) to be housed in corresponding grooves located in the edges (14) of the opening of the housing (11).

A l'intérieur du boítier (11) se trouve une caissette (12) amovible servant à recueillir des pièces de monnaie. Cette caissette une fois pleine est remplacée par une vide ce qui nécessite des ouvertures et fermetures régulières de la porte (1) de la caisse.Inside the housing (11) is a removable box (12) used to collect some coins. This box once full is replaced by a vacuum which requires regular opening and closing of the door (1) of the box.

La figure 3 et la figure 4 qui est une coupe selon A-A montrent une première variante du dispositif de verrouillage, selon l'invention, monté sur la face interne d'une porte de caisse (1). La came (2) et les plaques de verrouillage (4, 4') sont situés dans le même plan parallèle à la porte (1) et à une distance de celle-ci nécessaire au jeu mécanique.Figure 3 and Figure 4 which is a section along A-A show a first variant of the locking device, according to the invention, mounted on the internal face of a door body (1). The cam (2) and the locking plates (4, 4 ') are located in the same plane parallel to the door (1) and at a distance from it necessary for the game mechanical.

Dans une première réalisation, le corps de la serrure a une longueur supérieure à l'épaisseur de la porte. Afin de maintenir la came (2) à une distance minimale par rapport au plan de la porte (1), la fixation à l'axe de la serrure (7) est réalisée par l'intermédiaire d'un capot (6). Ce dernier, généralement cylindrique (6), entoure le corps de la serrure (8) et sa base est soudée à la came (2). La face supérieure du capot est traversée par l'axe de la serrure (7) qui y est fixé par un écrou.In a first embodiment, the body of the lock has a length greater than the thickness of the door. In order to keep the cam (2) at a minimum distance by relative to the plane of the door (1), the fixing to the axis of the lock (7) is carried out by through a cover (6). The latter, generally cylindrical (6), surrounds the body of the lock (8) and its base is welded to the cam (2). The upper side of the hood is crossed by the axis of the lock (7) which is fixed there by a nut.

Les plaques de verrouillage (4, 4') comportent des trous allongés formant des glissières. Les plaques (4, 4') sont posées sur des supports (5, 5') constitués chacun par une entretoise et une vis munie d'un écrou qui traverse l'entretoise et la glissière afin de maintenir leur position parallèle à la porte à une distance minimale permettant un jeu mécanique. Des ressorts (30, 30') relient les plaques de verrouillage afin de permettre leur retrait lors du déverrouillage de la porte.The locking plates (4, 4 ') have elongated holes forming slides. The plates (4, 4 ') are placed on supports (5, 5') each made up by a spacer and a screw provided with a nut which crosses the spacer and the slide in order to maintain their position parallel to the door at a minimum distance allowing mechanical play. Springs (30, 30 ') connect the plates locking to allow them to be removed when the door is unlocked.

Les figures 3 et 4 montrent la configuration du dispositif lorsque la porte (1) est verrouillée. En effet, les plaques de verrouillage (4, 4') dépassent des bords latéraux de la porte (1) dans le but de s'emboíter dans les rainures correspondantes du boítier de la caisse. Le bord inférieur de la porte (1) est muni d'une charnière.Figures 3 and 4 show the configuration of the device when the door (1) is locked. Indeed, the locking plates (4, 4 ') protrude from the side edges of the door (1) in order to fit into the corresponding grooves of the body of the case. The lower edge of the door (1) is provided with a hinge.

Une rotation de la clé dans la serrure (8) fait tourner la came (2) de façon à libérer les plaques de verrouillage (4, 4') qui ne s'appuient plus sur les bords de la came (en pointillé sur la figure). Les plaques (4, 4') quittent les rainures du boítier par un mouvement de translation en direction de la serrure (8) actionné par les ressorts (30, 30') tendus préalablement lors du verrouillage. (flèches P, P')A rotation of the key in the lock (8) turns the cam (2) so as to release the locking plates (4, 4 ') which no longer rest on the edges of the cam (in dotted on the figure). The plates (4, 4 ') leave the grooves of the housing by a translational movement towards the lock (8) actuated by the springs (30, 30 ') tensioned before locking. (arrows P, P ')

Une seconde réalisation illustrée par la figure 5 s'applique sur une porte (1) d'épaisseur égale à la longueur du corps de la serrure (8) de manière à le noyer entièrement dans l'épaisseur de la porte (1) en ne laissant dépasser que l'axe (7). La came (2) est ainsi directement fixée à cet axe parallèlement au plan de la porte (1) à une distance minimale de celui-ci (7) au moyen d'un écrou. Le capot (6) dans la zone centrale de la came (2) devient ainsi superflu. Les autres éléments tels que les plaques de verrouillage (4, 4') avec leurs supports coulissants (5, 5') et les ressorts (30, 30') sont semblables à ceux de la première variante.A second embodiment illustrated in FIG. 5 is applied to a door (1) of thickness equal to the length of the body of the lock (8) so as to drown it entirely in the thickness of the door (1) leaving only the axis (7) protruding. The cam (2) is thus directly fixed to this axis parallel to the plane of the door (1) to a minimum distance from it (7) by means of a nut. The cover (6) in the area central cam (2) becomes superfluous. Other items such as locking plates (4, 4 ') with their sliding supports (5, 5') and the springs (30, 30 ') are similar to those of the first variant.

La figure 7 et la figure 8 qui est une coupe selon A-A montrent une seconde variante du dispositif de verrouillage, selon l'invention, monté sur la face interne d'une porte (1) de caisse. La came (2) est située en dessous des plaques de verrouillage (4, 4') dans un plan parallèle à la porte (1) et à une distance de celle-ci nécessaire au jeu mécanique.Figure 7 and Figure 8 which is a section along A-A show a second variant of the locking device, according to the invention, mounted on the internal face of a door (1) cash. The cam (2) is located below the locking plates (4, 4 ') in a plane parallel to the door (1) and at a distance from the latter necessary for clearance mechanical.

La came (2) en général en forme de disque est fixée, en son centre, à l'axe de la serrure (7), parallèlement au plan de la porte (1). Deux plaques de verrouillages (4, 4') disposées symétriquement à gauche et à droite de la serrure (8) recouvrent partiellement la came (2).The generally disc-shaped cam (2) is fixed at its center to the axis of the lock (7), parallel to the plane of the door (1). Two locking plates (4, 4 ') arranged symmetrically to the left and right of the lock (8) overlap partially the cam (2).

Le corps de la serrure (8) est solidaire à la porte (1). Dans une première réalisation le corps de la serrure (8) a une longueur supérieure à l'épaisseur de la porte (1). Afin de maintenir la came (2) à une distance minimale permettant un jeu mécanique par rapport au plan de la porte (1), la fixation à l'axe de la serrure (7) est réalisée par l'intermédiaire d'un capot (6) comme dans la première variante.The body of the lock (8) is integral with the door (1). In a first realization the body of the lock (8) has a length greater than the thickness of the door (1). To to keep the cam (2) at a minimum distance allowing mechanical play by relative to the plane of the door (1), the fixing to the axis of the lock (7) is carried out by through a cover (6) as in the first variant.

La came (2) est munie de deux goupilles (3, 3') fixées symétriquement à gauche et à droite de l'axe de la serrure (7), dans une zone proche du bord et dirigées vers les plaques de verrouillage (4, 4') parallèles à la came (2). Ces goupilles sont engagées dans des glissières respectives (9, 9') dans chaque plaque de verrouillage (4, 4'). La longueur des goupilles (3, 3') dépassant de la came (2) est déterminée de façon à ce que leur extrémité soit située à fleur de la face supérieure des plaques de verrouillage (4, 4') lorsqu'elles se trouvent dans leur glissière (9, 9') correspondante. The cam (2) is provided with two pins (3, 3 ') fixed symmetrically to the left and to right of the axis of the lock (7), in an area close to the edge and directed towards the locking plates (4, 4 ') parallel to the cam (2). These pins are engaged in respective slides (9, 9 ') in each locking plate (4, 4'). The length of the pins (3, 3 ') protruding from the cam (2) is determined so that their end is located flush with the upper face of the plates locking (4, 4 ') when they are in their corresponding slide (9, 9').

Les plaques de verrouillage (4, 4') sont posées sur des supports (5, 5') similaires à ceux de la première variante qui maintiennent leur position parallèle au-dessus de la came (2) à une distance minimale permettant un jeu mécanique.The locking plates (4, 4 ') are placed on supports (5, 5') similar to those of the first variant which maintain their parallel position above the cam (2) at a minimum distance allowing mechanical play.

Les figures 7 et 8 montrent la configuration du dispositif lorsque la porte (1) est verrouillée. En effet, les plaques de verrouillage (4, 4') dépassent des bords supérieurs et latéraux de la porte (1) dans le but de s'emboíter dans les rainures correspondantes du boítier de la caisse.Figures 7 and 8 show the configuration of the device when the door (1) is locked. Indeed, the locking plates (4, 4 ') protrude from the edges upper and side of the door (1) in order to fit into the grooves corresponding to the case of the box.

Une rotation de la clé dans la serrure (8) fait tourner la came (2). Les goupilles (3, 3') parcourent leur glissière (9, 9') respectives dans les plaques de verrouillage (4, 4') (suivant les flèches G, G') tout en exerçant une force de poussée sur les plaques (4, 4') entraínant leur déplacement. Ces glissières (9, 9') sont disposées de façon à assurer un mouvement de translation des plaques de verrouillage (4, 4') en direction de la serrure (8), (suivant les flèches P, P'). Un tel mouvement s'effectue grâce aux trous allongés formant des glissières traversées par les vis des supports (5, 5'). Les plaques (4, 4') quittent les rainures du boítier permettant ainsi l'ouverture de la caisse.A rotation of the key in the lock (8) turns the cam (2). The pins (3, 3 ') run through their respective slide (9, 9 ') in the locking plates (4, 4') (following the arrows G, G ') while exerting a pushing force on the plates (4, 4 ') causing their displacement. These slides (9, 9 ') are arranged so as to ensuring a translational movement of the locking plates (4, 4 ') in the direction of the lock (8), (according to the arrows P, P '). Such a movement takes place thanks to elongated holes forming slides traversed by the support screws (5, 5 '). The plates (4, 4 ') leave the grooves of the housing thus allowing the opening of the checkout.

Les ressorts (30, 30') de la variante précédente ne sont plus nécessaires car les goupilles (3, 3') de la came (2) actionnent les plaques de verrouillage (4, 4') par des forces de poussée sur les bords de leur glissières (9, 9') aussi bien dans un sens (verrouillage) que dans l'autre (déverrouillage).The springs (30, 30 ') of the previous variant are no longer necessary because the pins (3, 3 ') of the cam (2) actuate the locking plates (4, 4') by thrust forces on the edges of their slides (9, 9 ') both in one direction (lock) than in the other (unlock).

Une seconde réalisation illustrée par la figure 9 s'applique sur une porte (1) d'épaisseur égale à la longueur du corps de la serrure (8). La came (2) est ainsi directement fixée à cet axe parallèlement au plan de la porte (1) à une distance minimale de celui-ci (7) au moyen d'un écrou. Les autres éléments du dispositif de verrouillage restent semblables à ceux de la variante avec une porte de plus faible épaisseur.A second embodiment illustrated in FIG. 9 is applied to a door (1) of thickness equal to the length of the body of the lock (8). The cam (2) is thus directly attached to this axis parallel to the plane of the door (1) at a distance minimum of this (7) by means of a nut. The other elements of the lock remain similar to those of the variant with a lower door thickness.

Une variante du dispositif de verrouillage selon l'invention illustrée par les figures 10 et 11 a pour but d'améliorer la sécurité du dispositif en cas d'infraction par perçage des goupilles 3 et 3' de la came. En effet dans la configuration représentée par les figures 7, 8 et 9, l'enlèvement des goupilles de la came (2) entraíne le déverrouillage de la porte par dégagement des plaques de verrouillage hors des rainures bordant le boítier de la caisse sous l'effet de la gravité. Pour pallier cet inconvénient, deux goupilles supplémentaires (31, 31') ont été ajoutées sur la came (2) de manière à dépasser de la surface de la came comme les premières goupilles (3, 3'). Elles sont situées dans la zone périphérique de la came et de part et d'autre du centre de celle-ci de façon à s'appuyer sur une portion de la tranche de chacune des plaques verrouillages (4, 4'). Le rôle de ces goupilles (31, 31') est de maintenir en position verrouillées les plaques de verrouillage (4, 4') en cas d'enlèvement des premières goupilles (3, 3').A variant of the locking device according to the invention illustrated by Figures 10 and 11 aims to improve the safety of the device in the event of a breach by drilling pins 3 and 3 'of the cam. Indeed in the configuration represented by the Figures 7, 8 and 9, the removal of the pins of the cam (2) causes the unlocking of the door by releasing the locking plates from the grooves bordering the body box under the effect of gravity. To overcome this drawback, two additional pins (31, 31 ') have been added to the cam (2) so that protrude from the surface of the cam like the first pins (3, 3 '). They are located in the peripheral zone of the cam and on either side of the center of the latter so as to rest on a portion of the edge of each of the plates locks (4, 4 '). The role of these pins (31, 31 ') is to keep in position locked the locking plates (4, 4 ') in case of removal of the first pins (3, 3 ').

Lors du déverrouillage de la porte par rotation de la came (2) exercée par la clé insérée dans la serrure, les goupilles (3, 3') s'engagent dans les glissières (9, 9') entraínant une translation des plaques de verrouillages (4, 4') en direction du centre de la porte comme illustré sur la figure 11. Les goupilles supplémentaires (31, 31') se dégagent de l'appui sur les plaques de verrouillage afin de les libérer pour l'ouverture de la porte (1).When unlocking the door by rotation of the cam (2) exerted by the key inserted in the lock, the pins (3, 3 ') engage in the slides (9, 9') causing a translation of the locking plates (4, 4 ') towards the center of the door as illustrated in figure 11. The additional pins (31, 31 ') are release support on the locking plates to free them for opening of the door (1).

Selon une autre variante du dispositif de verrouillage illustrée par les figures 12 et 13, les goupilles supplémentaires (31, 31') peuvent être remplacées par un ensemble constitué d'une goupille (40) solidaire de la porte (1) sur laquelle sont fixées deux lames de ressort (32, 32'). Cet ensemble est situé de préférence dans le voisinage de la came et à proximité des deux plaques de verrouillage. Chaque lame de ressort s'appuie sur une portion de la tranche de chacune des plaques de verrouillage en les maintenant dans la position verrouillée. Ces lames jouent le même rôle de maintien des plaques de verrouillage que les goupilles supplémentaires de la variante précédente.According to another variant of the locking device illustrated in FIGS. 12 and 13, the additional pins (31, 31 ') can be replaced by a assembly consisting of a pin (40) integral with the door (1) on which are fixed two leaf springs (32, 32 '). This set is preferably located in the near the cam and near the two locking plates. Each blade of spring rests on a portion of the edge of each of the plates locking by keeping them in the locked position. These blades play the same role of holding the locking plates as the pins additional from the previous variant.

Lors du déverrouillage de la porte (1), suite à la rotation de la came (2), les plaques de verrouillage (4, 4'), en se déplaçant en direction du centre de la porte, repoussent les lames de ressort (32, 32') l'une contre l'autre, les goupilles (3, 3') s'engageant dans leur glissières respectives (9, 9').When the door (1) is unlocked, following the rotation of the cam (2), the plates locking (4, 4 '), moving towards the center of the door, push back the spring leaves (32, 32 ') against each other, the pins (3, 3') engaging in their respective slides (9, 9 ').

Selon une autre variante un second ensemble de maintien à lame de ressort (41, 33, 33') peut être disposé en face du premier symétriquement par rapport au centre de la came (2). Les lames ressort (33, 33') de ce second ensemble contribuent à l'équilibre des forces exercées par les lames de ressort (32, 32') du premier ensemble sur les plaques de verrouillages (4, 4') en empêchant leur blocage éventuel dû au jeu mécanique entre les vis support (5, 5') et leurs glissières respectives.According to another variant, a second spring leaf holding assembly (41, 33, 33 ') can be arranged opposite the first symmetrically with respect to the center of the cam (2). The spring blades (33, 33 ') of this second set contribute to the balance of forces exerted by the spring leaves (32, 32 ') of the first together on the locking plates (4, 4 ') preventing their blocking possible due to mechanical play between the support screws (5, 5 ') and their slides respectively.
