Description

La présente invention concerne d'une façon générale les systèmes de sécurité pour chariots, tels que des chariots d'achats et des chariots à bagages qui sont mis à la disposition des usagers dans les magasins en libre service et dans les installations de transport telles que les gares et les aérogares.The present invention relates generally to safety systems for trolleys, such as shopping trolleys and baggage carts which are made available to users in self-service stores and in transport facilities such as stations and terminals.

Ces systèmes de sécurité, appelés consigneurs, ont pour objet d'éviter les vols de ces chariots et d'inciter les usagers à les ramener après usage à leur poste d'attente où ils sont emboîtés les uns dans les autres.These security systems, called loggers, are intended to prevent theft of these trolleys and to encourage users to return after use to their waiting station where they are nested in one another.

Ces consigneurs sont généralement constitués d'un boitier comportant d'un côté une fente d'introduction de clé et de l'autre une fente d'introduction de consigne. Ce boitier contient un mécanisme de verrou alternatif qui emprisonne la clé en libérant la consigne ou emprisonne la consigne en libérant la clé.These loggers generally consist of a housing having on one side a key introduction slot and the other a deposit introduction slot. This box contains an alternative lock mechanism that locks the key by releasing the instruction or imprisons the instruction by releasing the key.

Le brevet EP 286 460 décrit un mécanisme utilisant le mouvement de deux leviers, pivotant chacun autour d'un axe intermédiaire, les extrémités desdits leviers venant, d'un côté, en prise directe sur l'extrémité d'une clé et, de l'autre côté, venant en prise directe avec la tranche d'une pièce de consigne. Un ressort actionne une paillette qui verrouille le mouvement des leviers en position ouverte du coté clé, lorsque le mouvement d'introduction d'une consigne a fait pivoter lesdits leviers et dégager l'espace permettant l'engagement de ladite paillette entre les leviers. La réintroduction de la clé repousse la paillette à l'encontre du ressort et autorise le pivotement en sens inverse des leviers l'un vers l'autre et l'ouverture de leurs extrémités opposées pour libérer la consigne. Des ressorts auxiliaires agissant sur les leviers sollicitent ces derniers en position de fermeture du coté de la clé. En dépit de sa grande simplicité, un tel mécanisme est d'un assemblage compliqué en raison de la nécessité de mise en place dans le boitier de divers ressorts agissant dans des directions contraires sur les leviers et sur la paillette.The patent EP 286,460 describes a mechanism using the movement of two levers, each pivoting about an intermediate axis, the ends of said levers coming, on one side, in direct contact with the end of a key and, on the other side, in direct contact with the edge of a set piece. A spring actuates a straw which locks the movement of the levers in the open position of the key side, when the insertion movement of a setpoint has pivoted said levers and clear the space for the engagement of said straw between the levers. The reintroduction of the key pushes the straw against the spring and allows the pivoting in the opposite direction of the levers towards each other and the opening of their opposite ends to release the deposit. Auxiliary springs acting on the levers urge the latter in the closed position on the side of the key. Despite its great simplicity, such a mechanism is a complicated assembly in because of the need to install in the case of various springs acting in opposite directions on the levers and on the straw.

On connaît également un autre mode de réalisation d'un mécanisme de consigneur dans lequel les leviers agissent, d'un côté, directement sur la pièce de consigne et, de l'autre côté, sur un verrou basculant, actionné par un ressort. Le pêne de ce verrou basculant vient en service crocheter une lumière formant gâche pratiquée à l'extrémité distale de la clé. Comme dans le mécanisme précédent, la présence de plusieurs ressorts, l'un agissant sur le verrou basculant et les autres agissant sur les leviers, complique les opérations de montage du mécanisme dans le boitier du consigneur.There is also another embodiment of a locking mechanism in which the levers act, on one side, directly on the set piece and, on the other side, on a rocking latch actuated by a spring. The bolt of this tilting lock comes into use pick a strike-forming light made at the distal end of the key. As in the previous mechanism, the presence of several springs, one acting on the rocking latch and the other acting on the levers, complicates the mounting operations of the mechanism in the box of the consigner.

La présente invention a pour but de remédier à cet inconvénient et de proposer un mécanisme de verrou à consigne amélioré qui, tout en restant d'une grande compacité, ne présente plus les difficultés de montage des mécanismes antérieurs ci-dessus évoqués.The object of the present invention is to remedy this drawback and to propose an improved command lock mechanism which, while remaining very compact, no longer presents the difficulties of mounting the aforementioned prior mechanisms.

Selon l'invention, le mécanisme de verrouillage est du type à leviers pivotants agissant d'un coté en prise directe avec la consigne et de l'autre sur un verrou basculant dont une extrémité porte un pêne s'engageant dans une lumière de la clé. Ce mécanisme est caractérisé en ce que le verrou basculant a la forme générale d'une croix, les extrémités de la barre transversale de ladite croix portant chacune un plot d'appui et un ressort à lame plat étant disposé pardessus les leviers et le verrou basculant, ledit ressort comportant d'un coté deux pattes reposant sur les plots d'appui de la barre transversale du verrou basculant et de l'autre deux pattes coopérant chacune avec un des deux leviers pivotants pour solliciter en direction l'une de l'autre les extrémités desdits leviers dirigées vers le verrou basculant.According to the invention, the locking mechanism is of the type with pivoting levers acting on one side in direct contact with the instruction and on the other on a tilting latch, one end of which carries a bolt engaging in a key light. . This mechanism is characterized in that the rocking latch has the general shape of a cross, the ends of the transverse bar of said cross each carrying a support pad and a flat leaf spring being disposed above the levers and the rocking latch , said spring having on one side two tabs resting on the support pads of the transverse bar of the rocking lock and on the other two tabs each cooperating with one of the two pivoting levers to urge towards one of the other the ends of said levers directed towards the rocking lock.

Grâce à l'emploi d'un ressort plat monobloc agissant sur les leviers et sur le verrou basculant, on facilite grandement les opérations de montage du mécanisme du consigneur et l'on diminue l'encombrement du mécanisme qui peut-être logé dans une cassette très compacte.Thanks to the use of a one-piece flat spring acting on the levers and on the tilting bolt, the assembly operations of the mechanism of the consigner and it reduces the size of the mechanism that can be housed in a very compact cassette.

Cette construction présente l'avantage de constituer un boitier monobloc offrant une plus grande résistance aux efforts de traction et une plus grande facilité de montage, la face 3 d'entrée de clé étant intégrée au boitier 1. La face arrière 6, diamétralement opposée à la face avant 3, présente une fente d'entrée de clé qui n'est pas visible sur les figures. A l'intérieur du boitier 1, attenant à sa face arrière 6, on trouve un caisson 7 formant chambre de réception de la clé 8. Le caisson 7 présente un évidement 9 (ex : central) disposé selon l'axe longitudinal médian du boitier 1, ledit axe étant matérialisé par la ligne tiretée visible sur la Figure 2. L'évidement 9 du caisson 7 s'étend sur toute la hauteur de la paroi arrière du caisson et sur une partie de sa paroi supérieure, définissant une lumière pour le passage du pêne du verrou. L'espace interne du boitier 1 est divisé en deux zones par une cloison sensiblement médiane 10 : la zone se trouvant du côté de la face avant 3 est la zone de réception de la consigne 5, la zone se trouvant du côté de la face arrière 6 est la zone de réception de la clé 8. Dans cette dernière, entre la cloison 10 et le caisson 7, le plancher du boitier 1 porte un berceau 11 formant palier pour la barre transversale du verrou. Dans la zone de réception de la consigne 5 le plancher du boitier 1 porte un plateau 12 de réception de la consigne 5, disposé selon l'axe longitudinal médian dudit boitier, et deux plots 13 sur lesquels les leviers 14 sont chacun montés à pivotement autour d'un axe vertical. Les plots 13 sont situés à l'aplomb d'ouvertures 15 pratiquées dans le chant supérieur des cotés latéraux 1a, 1b du boitier 1.The Figure 2 presents in exploded view the various elements of the lock mechanism with reference which is housed in a cassette, itself mounted in the housing B1 shown in FIG. Figure 1 . The cassette housing this mechanism is constituted by a housing 1 closed by an upper cover 2. One of the vertical faces of the housing 1 referenced 3 incorporates a slot 4 for introducing coin or token deposit 5. By convention, this face 3 will be designated hereinafter as the front face of the cassette 1. It can be seen that the ends of the front face 3 protrude on either side of the opposite lateral sides 1a, 1b of the housing 1. The front face 3 extends height slightly above the upper edge of the side edges 1a, 1b and the opposite rear face 6. This construction has the advantage of providing a one-piece housing offering greater resistance to tensile stresses and greater ease of assembly , the key input face 3 being integrated in the housing 1. The rear face 6, diametrically opposite to the front face 3, has a key entry slot which is not visible in the figures. Inside the housing 1, adjacent to its rear face 6, there is a box 7 forming a receiving chamber of the key 8. The box 7 has a recess 9 (ex: central) disposed along the median longitudinal axis of the housing 1, said axis being indicated by the dashed line visible on the Figure 2 . The recess 9 of the box 7 extends over the entire height of the rear wall of the box and on a portion of its upper wall, defining a slot for the passage of the latch bolt. The internal space of the housing 1 is divided into two zones by a substantially median partition 10: the zone lying on the side of the front face 3 is the receiving zone of the setpoint 5, the zone lying on the side of the rear face 6 is the receiving zone of the key 8. In the latter, between the partition 10 and the box 7, the floor of the housing 1 carries a cradle 11 forming a bearing for the transverse bar of the lock. In the receiving zone of the instruction 5 the floor of the housing 1 carries a tray 12 for receiving the instruction 5, arranged along the median longitudinal axis of said housing, and two studs 13 on which the levers 14 are each pivotally mounted around a vertical axis. The studs 13 are located in line with openings 15 made in the upper edge of the lateral sides 1a, 1b of the casing 1.

Chaque levier 14 est essentiellement constitué d'une plaquette 16 dont le chant tourné vers l'axe longitudinal médian du boitier 1 présente une encoche semi-circulaire 19, ladite encoche étant destinée à venir en service en contact avec le chant d'une pièce de consigne 5 (par exemple de forme complémentaire). Le levier 14 comporte en outre un pivot intermédiaire 17 et une butée 18 de ressort.Each lever 14 essentially consists of a plate 16 whose edge turned towards the median longitudinal axis of the housing 1 has a semicircular notch 19, said notch being intended to come into use in contact with the edge of a piece of setpoint 5 (for example of complementary shape). The lever 14 further comprises an intermediate pivot 17 and a stop 18 of spring.

Le verrou est constitué par une pièce en forme générale de croix. La barre longitudinale 20 de la pièce porte vers son extrémité dirigée vers la face arrière 6 (lorsque le verrou est logé dans le boitier) deux protubérances 21 et 22 (s'étendant perpendiculairement à la barre, vers le haut) formant pêne d'engagement dans la fenêtre formant gâche 23 et qui est pratiquée dans l'empreinte de la clé 8. A l'opposé de ce pêne, la barre longitudinale 20 du verrou porte deux palettes 24 et 25 qui, en service, coopèrent avec les extrémités correspondantes des plaquettes 16 des leviers 14.The lock is constituted by a piece in the general shape of a cross. The longitudinal bar 20 of the part carries towards its end directed towards the rear face 6 (when the lock is housed in the housing) two protuberances 21 and 22 (extending perpendicular to the bar, upwards) forming engagement bolt in the striker window 23 and which is practiced in the imprint of the key 8. A the opposite of this bolt, the longitudinal bar 20 of the lock carries two vanes 24 and 25 which, in use, cooperate with the corresponding ends of the plates 16 of the levers 14.

La barre transversale 26 du verrou constitue l'axe horizontal de basculement de ce dernier et repose en service sur le berceau 11 du fond du boitier 1. Cette barre est perpendiculaire à l'axe longitudinal d'introduction de la clé ou de la consigne dans le boitier. Elle porte à chacune de ses deux extrémités opposées un plot 27, 28 d'appui pour les extrémités correspondantes des pattes formées dans le ressort plat R. De préférence chaque plot 27, 28 présente une pente inclinée vers l'avant du boitier 1.The transverse bar 26 of the latch constitutes the horizontal axis of tilting of the latter and rests in service on the cradle 11 of the bottom of the housing 1. This bar is perpendicular to the longitudinal axis of introduction of the key or the set in The box. It carries at each of its two opposite ends a stud 27, 28 for supporting the corresponding ends of the tabs formed in the flat spring R. Preferably each stud 27, 28 has a slope inclined towards the front of the housing 1.

Le ressort plat R comporte deux jeux de pattes destinées en service à venir en appui respectivement sur le verrou et sur les leviers 14. Les pattes arrière 29 et 30 du ressort se trouvent dans le même plan horizontal que ce dernier. En service, elles sont en appui respectivement sur les plots 27 et 28 portés par la barre transversale 26 du verrou. Les pattes avant 31 et 32 du ressort plat sont disposées dans un plan perpendiculaire à celui du ressort. En service, chaque patte avant 31, 32 du ressort passe entre le pivot 17 et la butée 18 d'un levier 14 correspondant et s'étend à travers une des ouvertures 15 pratiquées dans le chant supérieur des cotés latéraux 1a, 1b du boitier 1 sur laquelle elle prend appui. Entre les pattes avant 31 et 32, le ressort plat comporte une languette courbe 33. En service, cette languette courbe vient en appui contre la face supérieure de la pièce de consigne 5 et fait fonction de frein d'éjection pour ladite pièce. On notera que les pattes arrière 29,30, les pattes avant 31,32 et la languette 33 sont toutes raccordées à une partie centrale 35 sensiblement plane formant le corps du ressort.The flat spring R comprises two sets of tabs intended for future service bearing respectively on the latch and the levers 14. The rear legs 29 and 30 of the spring are in the same horizontal plane as the latter. In use, they are respectively bearing on the pads 27 and 28 carried by the transverse bar 26 of the lock. The front legs 31 and 32 of the flat spring are arranged in a plane perpendicular to that of the spring. In use, each front leg 31, 32 of the spring passes between the pivot 17 and the stop 18 of a corresponding lever 14 and extends through one of the openings 15 made in the upper edge of the lateral sides 1a, 1b of the housing 1 on which it leans. Between the front legs 31 and 32, the flat spring comprises a curved tongue 33. In use, this curved tongue bears against the upper face of the set piece 5 and acts as an ejection brake for said piece. Note that the rear legs 29,30, the front lugs 31,32 and the tongue 33 are all connected to a substantially planar central portion 35 forming the body of the spring.

Le couvercle 2 présente sur son coté orienté vers la face arrière du boitier de cassette 1 un évidement 34. En service, cet évidement est destiné au passage de l'extrémité de la protubérance 22 du verrou, de manière que ladite protubérance vienne en appui sur le boitier B1 du consigneur à travers le couvercle du boitier 1 de la cassette C1 (figure 1).The lid 2 has on its side facing the rear face of the cassette case 1 a recess 34. In use, this recess is intended for the passage of the end of the protuberance 22 of the lock, so that said protuberance comes to bear on the housing B1 of the consigner through the cover of the housing 1 of the cassette C1 ( figure 1 ).

En raison de ces dispositions, les crochets des leviers pivotants n'ont pas d'effet sur la clé, ils servent uniquement à libérer ou emprisonner la pièce de consigne. Les efforts de traction sur la clé sont repris par le boitier et non pas par la cassette. L'axe 26 du verrou sert uniquement au pivotement, il n'est pas utile pour reprendre les efforts de traction, ce qui permet d'avoir un axe de verrou relativement fin.Because of these provisions, the hooks of the pivoting levers have no effect on the key, they are only used to release or imprison the set piece. The traction forces on the key are taken up by the box and not by the cassette. The axis 26 of the latch is only for pivoting, it is not useful to resume the tensile forces, which allows to have a relatively thin latch axis.

La clé est libérée ou emprisonnée par le verrou basculant en forme de croix dont la partie orientée vers les leviers 14 comporte les deux palettes 24, 25 susceptibles de coopérer avec la partie d'extrémité correspondante des leviers pivotants pour bloquer ou libérer le mouvement de rotation du verrou.The key is released or trapped by the rocker-shaped latch whose portion directed towards the levers 14 comprises the two vanes 24, 25 capable of cooperating with the corresponding end portion of the pivoting levers to block or release the rotational movement lock.

La Figure 3A illustre schématiquement le verrouillage de la clé 8 : lors de l'introduction de la clé 8 dans la fente correspondante de la face arrière 6 du boitier 1, la poussée du nez de clé sur la protubérance 21 de la barre transversale 20 du verrou provoque le basculement de ce dernier dans le sens anti-horaire à l'encontre de la force d'appui des pattes arrière 29 et 30 du ressort plat et l'engagement de la protubérance 22 dans la fenêtre 23 de la clé 8. Simultanément, les palettes 24 et 25 du verrou s'écartent des extrémités correspondantes des leviers 14 qui, sous l'effet des pattes avant 31 et 32 du ressort plat peuvent pivoter l'une vers l'autre, provoquant ainsi l'ouverture de l'extrémité avant opposée des leviers 14 (écartement transversal des deux extrémités opposées) et la libération de la pièce de consigne 5. Dans cette position, le retour du verrou à sa position initiale est empêché par l'appui des extrémités arrières des leviers 14 sur le dessus des palettes 24 et 25.The Figure 3A schematically illustrates the locking of the key 8: during the introduction of the key 8 in the corresponding slot of the rear face 6 of the housing 1, the thrust of the key nose on the protrusion 21 of the cross bar 20 of the lock causes the tilting of the latter in the counterclockwise direction against the bearing force of the rear legs 29 and 30 of the flat spring and the engagement of the protuberance 22 in the window 23 of the key 8. Simultaneously, the pallets 24 and 25 of the lock deviate from the corresponding ends of the levers 14 which, under the effect of the front lugs 31 and 32 of the flat spring can pivot towards one another, thus causing the opening of the opposite front end levers 14 (transverse spacing of the two opposite ends) and the release of the set piece 5. In this position, the return of the lock to its initial position is prevented by the support of the rear ends of the levers 14 on the top of the letters 24 and 25.

Comme représenté en coupe sur la figure 3B, le verrou est monté en appui à l'intérieur du boitier B1 sur la pièce C5 de reprise d'effort qui fait office de socle d'appui. La face avant de la protubérance 22 vient s'adosser à une paroi avant 40 de la pièce C5 et la face inférieure de la partie centrale du verrou repose sur un élément de support solidaire de ladite pièce C5. Ainsi, en cas de traction exercée sur la clé en position verrouillée et donc sur le verrou, les efforts sont retransmis au boitier par l'intermédiaire de la pièce C5 montée solidement contre la structure du boitier.As shown in section on the figure 3B , the latch is mounted in support of the housing B1 on the C5 piece of effort recovery which serves as a support base. The front face of the protuberance 22 is leaned against a front wall 40 of the part C5 and the lower face of the central part of the latch rests on a support member integral with said part C5. Thus, in the case of traction exerted on the key in the locked position and thus on the latch, the forces are transmitted back to the housing via the part C5 mounted firmly against the structure of the housing.

La Figure 4 illustre schématiquement le déverrouillage de la clé 8 : l'introduction de la pièce de la pièce de consigne 5 provoque l'écartement des extrémités des leviers 14 à l'encontre de la force des pattes avant 31 et 32 du ressort, ce qui dégage l'espace nécessaire pour le montée des palettes 24 et 25 du verrou entre les extrémités arrières correspondantes des leviers 14. Ce mouvement ascendant provient de la rotation du verrou dans le sens horaire et qui est provoquée par l'appui des pattes arrière 29 et 30 du ressort sur les plots d'extrémité 27 et 28 de la barre transversale 26 du verrou. Simultanément, cette rotation du verrou provoque le dégagement de la protubérance 22 par rapport à la fenêtre 23 de la clé 8. La clé 8 peut alors être retirée du boitier 1 de la cassette par simple traction axiale. Dans cette position, le retour du verrou est empêché par le blocage des palettes 24 et 25 entre les extrémités arrières correspondantes des leviers 14.The Figure 4 schematically illustrates the unlocking of the key 8: the introduction of the part of the set piece 5 causes the spacing of the ends of the levers 14 against the force of the front legs 31 and 32 of the spring, which releases the space required for the rise of the pallets 24 and 25 of the lock between the corresponding rear ends of the levers 14. This upward movement comes from the rotation of the latch in the clockwise direction and which is caused by the support of the rear legs 29 and 30 of the spring on the end pads 27 and 28 of the transverse bar 26 of the lock. Simultaneously, this rotation of the lock causes the release of the protrusion 22 relative to the window 23 of the key 8. The key 8 can then be removed from the casing 1 of the cassette by simple axial tension. In this position, the return of the lock is prevented by the locking of the vanes 24 and 25 between the corresponding rear ends of the levers 14.
