Abstract

The lock (6) has a locking rod (8) cooperating with bores (9, 10) of a casement (3) and a fixed wall (2a) respectively to interdict pivoting of the casement with respect to the wall. The rod is displaced by an operating unit e.g. handle, for permitting unlocking of the casement. A cam (16) controls deflating of an inflatable sealing ring (7), between the casement and the wall, through sliding of a slide (14) of the unit before displacement of the rod. The slide is connected to the rod by a spring (22).

Description

Le domaine technique de l'invention est celui des verrous permettant d'assurer le blocage d'un ouvrant pivotant par rapport à une paroi fixe, et plus particulièrement celui des verrous assurant le blocage d'un ouvrant d'un véhicule blindé.The technical field of the invention is that of the locks for ensuring the locking of a pivoting opening relative to a fixed wall, and more particularly that of the locks for locking an opening of a shielded vehicle.

Le plus souvent les ouvrants de véhicules blindés comportent au moins un joint d'étanchéité gonflable interposé entre l'ouvrant et la paroi. De tels joints d'étanchéité ont pour fonction d'assurer une protection du véhicule vis-à-vis des menaces bactériologiques ou chimiques et ils permettent également d'assurer une étanchéité à l'eau facilitant les passages de gués.Most often the opening of armored vehicles comprise at least one inflatable seal interposed between the opening and the wall. Such seals have the function of providing protection of the vehicle vis-à-vis bacteriological or chemical threats and they also provide a watertight seal facilitating fording fords.

Le joint est gonflé à l'aide d'un compresseur qui est commandé après fermeture de l'ouvrant. Inversement le joint est dégonflé avant l'ouverture de l'ouvrant.The seal is inflated using a compressor that is controlled after closing the door. Conversely the seal is deflated before the opening of the opening.

Les verrous connus comportent une tige coulissante qui coopère avec un premier alésage de l'ouvrant et avec un deuxième alésage de la paroi de façon à interdire tout pivotement relatif de l'ouvrant par rapport à la paroi.Known locks comprise a sliding rod which cooperates with a first bore of the opening and with a second bore of the wall so as to prohibit any relative pivoting of the opening relative to the wall.

La tige peut être déplacée à l'aide d'un organe de manoeuvre (par exemple une poignée) pour permettre le déverrouillage.The rod can be moved using an actuator (eg a handle) to allow unlocking.

Un des inconvénients des verrous connus est que la tige se trouve fréquemment mise en contrainte par le gonflage du joint. Il peut en résulter un coincement de la tige dans son alésage qui gêne et parfois même empêche le déverrouillage et l'ouverture de l'ouvrant.One of the disadvantages of known locks is that the rod is frequently stressed by the inflation of the seal. This can result in jamming of the rod in its bore which hinders and sometimes even prevents unlocking and opening of the opening.

Ce coincement intervient plus particulièrement lorsque l'ouvrant comporte au moins deux plans sécants qui sont en contacts avec deux plans correspondants de la paroi. De tels ouvrants sont classiques sur les véhicules blindés en raison des formes particulières des parois.This jamming occurs more particularly when the opening comprises at least two secant planes which are in contact with two corresponding planes of the wall. Such openings are conventional on armored vehicles because of the particular shapes of the walls.

En effet le gonflage d'un joint au niveau de tels plans sécants crée un effort qui coupe l'axe de la tige et crée un couple de coincement de cette dernière.In fact the inflation of a joint at such secant planes creates a force that cuts the axis of the rod and creates a wedge torque of the latter.

C'est le but de l'invention que de proposer un verrou permettant d'éviter tout coincement de la tige.It is the object of the invention to provide a lock to prevent jamming of the rod.

Par ailleurs le verrou selon l'invention comporte des moyens permettant son actionnement tout aussi aisément à partir de l'extérieur du véhicule pour permettre éventuellement de dégager des occupants en cas d'accident.Furthermore, the lock according to the invention comprises means for its actuation just as easily from the outside of the vehicle to possibly clear occupants in case of accident.

Ainsi l'invention a pour objet un verrou assurant le blocage d'un ouvrant pivotant par rapport à une paroi fixe, un joint d'étanchéité gonflable étant interposé entre l'ouvrant et la paroi, verrou comportant une tige coulissante coopérant avec un premier alésage de l'ouvrant et avec un deuxième alésage de la paroi de façon à interdire tout pivotement relatif de l'ouvrant par rapport à la paroi, la tige pouvant être déplacée à l'aide d'un organe de manoeuvre pour permettre le déverrouillage, verrou caractérisé en ce que l'organe de manoeuvre comporte un tiroir coulissant portant des moyens de commande du dégonflage du joint, le tiroir étant relié à la tige de verrouillage par l'intermédiaire d'un moyen ressort, la commande du dégonflage étant assurée par le coulissement du tiroir avant le déplacement de la tige de verrouillage elle-même.Thus, the subject of the invention is a lock for locking a pivoting leaf with respect to a fixed wall, an inflatable gasket being interposed between the leaf and the wall, a bolt comprising a sliding rod cooperating with a first bore. of the opening and with a second bore of the wall so as to prohibit any relative pivoting of the opening relative to the wall, the rod being movable by means of an actuating member to allow the unlocking, latch characterized in that the actuating member comprises a sliding drawer carrying deflation control means of the seal, the slide being connected to the locking rod via a spring means, the control of the deflation being ensured by the slide the drawer before moving the locking rod itself.

Selon une autre caractéristique de l'invention, le tiroir coulisse entre une position de verrouillage et une position de déverrouillage, et lorsque le tiroir se trouve en position de déverrouillage, le moyen ressort exerce un effort sur la tige, amène celle-ci en butée contre le tiroir et la dégage ainsi complètement de sa position de verrouillage.According to another characteristic of the invention, the drawer slides between a locking position and an unlocking position, and when the drawer is in the unlocking position, the spring means exerts a force on the rod, brings it into abutment against the drawer and thus releases it completely from its locking position.

Le tiroir pourra être relié à la tige de verrouillage par l'intermédiaire d'un axe de manoeuvre comportant une extrémité solidaire du tiroir et portant une tête coulissant dans un alésage de la tige, le moyen ressort est alors interposé entre la tête et un lamage de l'alésage interne de la tige.The slide can be connected to the locking rod via an operating shaft having an end secured to the slide and carrying a sliding head in a bore of the rod, the spring means is then interposed between the head and a counterbore the internal bore of the stem.

Les moyens de commande du dégonflage pourront comprendre une came solidaire du tiroir, came coopérant avec un doigt de commande d'un distributeur pneumatique.The deflation control means may comprise a cam integral with the slide, cam cooperating with a control finger of a pneumatic distributor.

Le tiroir coulissant et la tige seront avantageusement solidaires d'un support assurant leur fixation sur la paroi.The sliding drawer and the rod will advantageously secured to a support ensuring their attachment to the wall.

Le tiroir coulissant peut de préférence pivoter par rapport au support lorsqu'il se trouve en position de déverrouillage et il comporte des moyens assurant dans cette position pivotée l'immobilisation en translation du tiroir dans sa position de déverrouillage.The sliding drawer can preferably pivot relative to the support when it is in the unlocked position and it comprises means ensuring in this pivoted position immobilization in translation of the slide in its unlocked position.

Les moyens assurant le maintien du tiroir en position de déverrouillage sont par exemple constitués par la came coopérant avec une butée du support.The means ensuring the maintenance of the slide in the unlocked position are for example constituted by the cam cooperating with a stop of the support.

Le verrou pourra avantageusement comprendre un moyen ressort interposé entre le support et le tiroir et permettant d'amener le tiroir de sa position de déverrouillage à sa position de verrouillage.The lock may advantageously comprise a spring means interposed between the support and the drawer and for bringing the drawer from its unlocking position to its locking position.

Selon un mode particulier de réalisation, le verrou pourra comprendre un dispositif d'ouverture de secours solidaire de l'ouvrant, dispositif comportant un poussoir solidaire d'une poignée, poussoir destiné à coopérer avec la tête de l'axe de manoeuvre de façon à pousser le tiroir de sa position de verrouillage vers sa position de déverrouillage.According to a particular embodiment, the lock may comprise an emergency opening device secured to the opening, device comprising a push-button secured to a handle, a push-button intended to cooperate with the head of the operating shaft so as to push the drawer from its lock position to its unlock position.

Des moyens pourront être prévus pour permettre d'entraîner en rotation le tiroir à partir du poussoir, afin de permettre de positionner le tiroir dans sa position de déverrouillage.Means may be provided to allow to rotate the drawer from the pusher, to allow to position the drawer in its unlocked position.

L'invention sera mieux comprise à la lecture de la description qui va suivre d'un mode particulier de réalisation, description faite en référence aux dessins annexés et dans lesquels :

The invention will be better understood on reading the following description of a particular embodiment, a description given with reference to the appended drawings and in which:
  • FIG. 1 shows the exterior of a vehicle with an opening leaf and makes it possible to locate the lock according to the invention,
  • FIG. 2 is a view in longitudinal section of an exemplary embodiment of a lock according to the invention, the lock being represented in the locking position,
  • FIGS. 3a, 3b and 3c show in schematic figures, three successive stages of the opening of a lock according to the invention, FIG. 3a shows the device in the locked position, FIG. 3b shows the lock when the drawer is moved and before sliding of the rod, FIG. 3c shows the lock after sliding of the rod,
  • Figure 3d shows in partial top view the cooperation of the end of the pusher with the rod, and
  • Figure 4 is a detail view showing the means ensuring the maintenance of the drawer in the unlocked position.

La figure 1 montre (en vue partielle) la partie avant d'un véhicule blindé 1 qui présente une paroi comportant deux pans inclinés 2a et 2b. Un ouvrant 3 est disposé au niveau de cette partie avant et il est monté pivotant par rapport à un arbre 4 auquel il est lié par un bras 5.Figure 1 shows (in partial view) the front portion of an armored vehicle 1 having a wall having two inclined faces 2a and 2b. An opening 3 is disposed at this front portion and is pivotally mounted relative to a shaft 4 to which it is connected by an arm 5.

L'ouverture de l'ouvrant est interdite à l'aide d'un verrou 6 qui s'interpose entre l'ouvrant 3 et la paroi 2a.The opening of the opening is prohibited by means of a latch 6 which is interposed between the opening 3 and the wall 2a.

On voit sur la figure 1 une partie 6a du verrou 6 qui est disposée à l'extérieur de l'ouvrant 3 et une partie 6b qui se trouve à l'intérieur du véhicule et solidaire de la paroi 2a.We see in Figure 1 a portion 6a of the latch 6 which is disposed outside the opening 3 and a portion 6b which is inside the vehicle and secured to the wall 2a.

Cette partie interne au véhicule est rendue visible sur la figure 1 par une découpe partielle de la paroi 2a.This portion inside the vehicle is made visible in Figure 1 by a partial cut of the wall 2a.

La figure 2 montre d'une façon plus détaillée la structure du verrou 6 proposé par l'invention.Figure 2 shows in more detail the structure of the lock 6 proposed by the invention.

On voit sur cette figure qu'un joint d'étanchéité gonflable 7 est disposé dans une gorge de l'ouvrant 3 et qu'il s'interpose ainsi entre l'ouvrant 3 et la paroi 2a. Le joint pourrait également être logé dans une gorge de la paroi 2a.We see in this figure that an inflatable seal 7 is disposed in a groove of the opening 3 and thus interposes between the opening 3 and the wall 2a. The seal could also be housed in a groove of the wall 2a.

Le verrou 6 comprend une tige 8 coulissante qui coopère avec un premier alésage 9, solidaire de l'ouvrant 3, et avec un deuxième alésage 10 porté par la paroi 2a. La tige 8 constitue ainsi un obstacle qui, lorsqu'il est engagé simultanément dans les deux alésages 9 et 10, interdit tout pivotement relatif de l'ouvrant 3 par rapport à la paroi 2a.The lock 6 comprises a sliding rod 8 which cooperates with a first bore 9, secured to the opening 3, and with a second bore 10 carried by the wall 2a. The rod 8 thus constitutes an obstacle which, when it is engaged simultaneously in the two bores 9 and 10, prohibits any relative pivoting of the opening 3 with respect to the wall 2a.

D'un point de vue structurel, le premier alésage 9 est porté par une douille 11 qui est vissée dans un taraudage de l'ouvrant 3. On pourrait alternativement coller la douille dans un alésage de l'ouvrant.From a structural point of view, the first bore 9 is carried by a sleeve 11 which is screwed into a tapping of the opening 3. Alternatively, the sleeve could be glued into a bore of the opening.

Par ailleurs, le deuxième alésage 10 est aménagé dans un support 12 qui est fixé à la paroi 2a par des vis 13.Moreover, the second bore 10 is arranged in a support 12 which is fixed to the wall 2a by screws 13.

Selon une caractéristique importante de l'invention, la tige 8 peut être déplacée à l'aide d'un organe de manoeuvre qui comporte un tiroir 14 monté coulissant dans le support 12.According to an important characteristic of the invention, the rod 8 can be moved with the aid of an operating member which comprises a slide 14 slidably mounted in the support 12.

Une poignée 15 de manoeuvre est fixée à l'extrémité du tiroir 14 et permet à un opérateur disposé à l'intérieur du véhicule d'exercer une traction sur le tiroir 14 suivant une direction D.A handle 15 is attached to the end of the slide 14 and allows an operator disposed within the vehicle to exert traction on the slide 14 in a direction D.

Le tiroir 14 porte par ailleurs des moyens 16 permettant de commander le dégonflage du joint 7.The drawer 14 also carries means 16 for controlling the deflation of the gasket 7.

Ces moyens 16 comprennent un profil de came qui est solidaire du tiroir 14 et qui coopère avec un doigt de commande 17 d'un distributeur pneumatique 18.These means 16 comprise a cam profile which is integral with the slide 14 and which cooperates with a control finger 17 of a pneumatic distributor 18.

Ce distributeur est relié par des tubulures 19 au circuit pneumatique de gonflage / dégonflage du joint 7. Un tel circuit est classique et il n'est donc pas nécessaire de le décrire en détails.This distributor is connected by tubings 19 to the pneumatic circuit for inflating / deflating the seal 7. Such a circuit is conventional and it is therefore not necessary to describe it in detail.

La liaison entre la tige 8 et le tiroir 14 est assurée par l'intermédiaire d'un axe de manoeuvre 20 qui comporte une extrémité 20a solidaire du tiroir 14. Cette extrémité 20a est ici filetée et vissée dans le tiroir.The connection between the rod 8 and the slide 14 is provided by means of an operating shaft 20 which has an end 20a integral with the slide 14. This end 20a is here threaded and screwed into the drawer.

L'axe de manoeuvre 20 porte une tête 20b qui coulisse dans un alésage 21 de la tige 8.The operating shaft 20 carries a head 20b which slides in a bore 21 of the rod 8.

Un moyen ressort 22 est disposé dans l'alésage 21 et il est interposé entre la tête 20b et un lamage délimitant le fond de l'alésage 21.A spring means 22 is disposed in the bore 21 and is interposed between the head 20b and a countersink defining the bottom of the bore 21.

Selon une autre caractéristique de l'invention, les différentes pièces (et notamment la raideur du ressort 22) sont dimensionnées de telle sorte que, lorsqu'un opérateur exerce une traction sur la poignée 15, la commande du dégonflage est assurée par le coulissement du tiroir 14 avant que la tige de verrouillage 8 ne se soit elle-même déplacée.According to another characteristic of the invention, the various parts (and in particular the stiffness of the spring 22) are dimensioned such that, when an operator exerts a pull on the handle 15, the control of the deflation is ensured by the sliding of the drawer 14 before the locking rod 8 has moved itself.

Le fonctionnement du dispositif est explicité sur les figures 3a, 3b et 3c qui le montrent d'une façon schématique (les mêmes repères correspondant cependant aux même composants déjà repérés sur la figure 2).The operation of the device is explained in Figures 3a, 3b and 3c which show it schematically (the same references, however, corresponding to the same components already identified in Figure 2).

Sur ces schémas fonctionnels, le joint 7 est représenté positionné sur la paroi 2a.In these functional diagrams, the seal 7 is shown positioned on the wall 2a.

Le dispositif est représenté sur la figure 3a dans sa position de verrouillage (même position que pour la figure 2).The device is shown in Figure 3a in its locking position (same position as in Figure 2).

Un opérateur exerce une traction sur la poignée 15 et suivant la direction D. La figure 3b montre le tiroir 14 qui se trouve ainsi déplacé. Le profil de came 16 provoque le basculement du doigt de commande 17 et le distributeur pneumatique 18 provoque le dégonflage du joint 7.An operator pulls on the handle 15 and in the direction D. Figure 3b shows the drawer 14 which is thus moved. The cam profile 16 causes the control finger 17 to tilt and the pneumatic distributor 18 causes the gasket 7 to deflate.

Le déplacement du tiroir 14 entraîne l'axe de manoeuvre 20 qui comprime le ressort 22 par sa tête 20b (le dessin est très schématique et ne préjuge pas de l'encombrement réel du ressort une fois comprimé).The displacement of the slide 14 drives the operating shaft 20 which compresses the spring 22 by its head 20b (the drawing is very schematic and does not prejudge the actual size of the spring once compressed).

Le ressort 22 ainsi comprimé exerce une force F sur la tige 8, ce qui a pour effet de pousser la tige 8 vers le tiroir 14 et conduit au déverrouillage de l'ouvrant 3.The spring 22 thus compressed exerts a force F on the rod 8, which has the effect of pushing the rod 8 towards the slide 14 and leads to the unlocking of the opening 3.

La figure 3c montre le verrou 6 dans sa position de déverrouillage. La tige 8 a été poussée par le ressort 22 contre le tiroir 14. Dans cette position elle sort du premier alésage 9 de la douille 11 et se dégage ainsi complètement de sa position de verrouillage.Figure 3c shows the latch 6 in its unlocking position. The rod 8 has been pushed by the spring 22 against the slide 14. In this position it leaves the first bore 9 of the sleeve 11 and thus disengages completely from its locking position.

Ainsi, avec l'invention, il n'est pas nécessaire que la tige de verrouillage 8 soit complètement dégagée pour que le joint d'étanchéité 7 soit dégonflé.Thus, with the invention, it is not necessary that the locking rod 8 is completely disengaged so that the seal 7 is deflated.

Une fois le joint dégonflé, les contraintes mécaniques qui s'exercent transversalement sur la tige 8 disparaissent, cette dernière n'est plus coincée et le déverrouillage est assuré.Once the seal deflated, the mechanical stresses exerted transversely on the rod 8 disappear, the latter is no longer stuck and unlocking is ensured.

Une fois dans sa position de déverrouillage, il est nécessaire d'assurer le maintien du verrou indépendamment de la traction exercée par l'opérateur sur la poignée 15.Once in its unlocking position, it is necessary to maintain the lock independently of the traction exerted by the operator on the handle 15.

Pour assurer un tel maintien, on prévoit la possibilité de faire pivoter le tiroir 14 par rapport au support 12 (rotation R sur la figure 3c).To ensure such a maintenance, it is provided the possibility of pivoting the slide 14 relative to the support 12 (rotation R in Figure 3c).

Pour cela, le logement du support 12 dans lequel coulisse le tiroir 14 est un alésage cylindrique 23 qui comporte une rainure latérale 24 qui permet le passage de la came 16.For this, the housing of the support 12 in which slides the slide 14 is a cylindrical bore 23 which has a lateral groove 24 which allows the passage of the cam 16.

On voit sur la figure 4 que la rainure latérale 24 comporte une partie élargie 25 et présente ainsi une surface de butée 26 contre laquelle s'applique la came 16 après translation et pivotement du tiroir 14.It can be seen in FIG. 4 that the lateral groove 24 has an enlarged portion 25 and thus has an abutment surface 26 against which the cam 16 applies after translation and pivoting of the slide 14.

Un pivotement du tiroir 14 en sens inverse permettra d'autoriser à nouveau la translation du tiroir dans son support 12.A pivoting of the slide 14 in the opposite direction will again allow the translation of the slide in its support 12.

Après fermeture de l'ouvrant 3, si on souhaite verrouiller ce dernier, l'opérateur fait donc pivoter le tiroir 14, ce qui autorise à nouveau sa translation. Le tiroir 14 est déplacé ensuite dans le sens inverse du sens D pour repousser la tige 8 dans l'alésage 9 et verrouiller ainsi l'ouvrant 3.After closure of the opening 3, if it is desired to lock the latter, the operator thus rotates the slide 14, which again allows its translation. The slide 14 is then moved in the direction opposite to the direction D to push the rod 8 into the bore 9 and thus lock the opening 3.

Afin de faciliter le retour du tiroir 14 dans sa position de verrouillage, un moyen ressort 27 (voir figure 1) est interposé entre le support 12 et le tiroir 14.In order to facilitate the return of the slide 14 to its locking position, a spring means 27 (see FIG. 1) is interposed between the support 12 and the slide 14.

Ce ressort 27 appuie d'un côté sur un épaulement du tiroir 14 et de l'autre sur une rondelle d'arrêt 28 fixée dans une gorge du support 12.This spring 27 presses on one side on a shoulder of the slide 14 and on the other on a locking washer 28 fixed in a groove of the support 12.

Pour la simplification des figures, le ressort 27 n'est pas représenté sur les figures 3a,3b et 3c.For simplification of the figures, the spring 27 is not shown in Figures 3a, 3b and 3c.

On notera également que l'étanchéité entre l'extérieur et l'intérieur du véhicule est assurée grâce à la mise en place de différents joints. On placera ainsi un premier joint torique 35 entre la tige 8 et le support 12 et un deuxième joint torique 36 entre la tête 20b de l'axe 20 et la tige 8 (voir figure 2). Ces joints ne sont pas représentés aux figures 3a,3b et 3c.Note also that the seal between the outside and inside of the vehicle is ensured through the establishment of different joints. This will place a first O-ring 35 between the rod 8 and the support 12 and a second O-ring 36 between the head 20b of the axis 20 and the rod 8 (see Figure 2). These joints are not shown in Figures 3a, 3b and 3c.

Pour des raisons de sécurité, le verrou proposé par l'invention comporte également un dispositif d'ouverture de secours, solidaire de l'ouvrant 3.For security reasons, the lock proposed by the invention also comprises an emergency opening device, secured to the opening 3.

Le descriptif précédent montre que pour assurer une telle ouverture il est nécessaire que le dispositif de secours puisse:

  • → d'une part pousser le tiroir 14 à partir de l'extérieur du véhicule et,
  • → d'autre part faire pivoter ce tiroir pour assurer son maintien en position déverrouillée.
The foregoing description shows that to ensure such an opening it is necessary that the emergency device can:
  • → on the one hand push the drawer 14 from the outside of the vehicle and,
  • → on the other hand, rotate this drawer to keep it in the unlocked position.

Le dispositif de secours comporte un poussoir 29 solidaire d'une poignée 30. Ce poussoir 29 est monté coulissant dans la douille 11 qui est fixée à l'ouvrant 3.The emergency device comprises a pusher 29 integral with a handle 30. This pusher 29 is slidably mounted in the sleeve 11 which is fixed to the opening 3.

Le poussoir 29 comporte une extrémité 29a aplatie en forme de lame qui est destinée à venir en appui sur la tête 20b de l'axe de manoeuvre 20 (voir figure 3d).The pusher 29 has a flattened end 29a in the form of a blade which is intended to bear on the head 20b of the operating shaft 20 (see FIG. 3d).

L'extrémité 29a du poussoir est maintenue en appui sur la tête 20b par l'action d'un ressort 32.The end 29a of the pusher is held in abutment on the head 20b by the action of a spring 32.

L'alésage 21 de la tige 8 comporte par ailleurs deux rainures longitudinales 33 dans lesquelles pénètre la lame 29a.The bore 21 of the rod 8 further comprises two longitudinal grooves 33 into which the blade 29a.

La lame 29a se positionne dans les rainures 33 et peut donc ainsi pousser la tête 20b au travers de l'alésage 21 sans difficultés.The blade 29a is positioned in the grooves 33 and can thus push the head 20b through the bore 21 without difficulty.

Ainsi, lorsqu'un opérateur situé à l'extérieur du véhicule 1 enfonce le poussoir 29 suivant la direction E, il pousse l'axe de manoeuvre 20 qui entraîne le tiroir 14.Thus, when an operator located outside the vehicle 1 pushes the pusher 29 in the direction E, it pushes the operating shaft 20 which drives the slide 14.

La séquence d'ouverture est alors analogue à celle qui a été décrite précédemment: le tiroir 14 commande le dégonflage du joint 7, puis la tige 8 poussée par le ressort 22 passe en position déverrouillée en se dégageant de l'alésage 9.The opening sequence is then similar to that described above: the slide 14 controls the deflation of the seal 7, then the rod 8 pushed by the spring 22 goes into unlocked position by disengaging the bore 9.

Il est donc tout aussi aisé de commander le déverrouillage du verrou 6 depuis l'extérieur que depuis l'intérieur.It is therefore just as easy to control the unlocking of the lock 6 from the outside as from the inside.

Des moyens sont par ailleurs prévus pour permettre de faire pivoter le tiroir 14 à partir du poussoir 29.Means are also provided to allow the drawer 14 to be pivoted from the pusher 29.

La forme de lame 29a de l'extrémité du poussoir 29 est engagée dans les rainures 33. Le pivotement du poussoir 29 entraîne donc le pivotement de la tige 8.The blade shape 29a of the end of the pusher 29 is engaged in the grooves 33. The pivoting of the pusher 29 thus causes the rod 8 to pivot.

Par ailleurs, un moyen 34 est prévu pour assurer l'entraînement en rotation du tiroir 14 par la tige 8. Ce dernier moyen, représenté schématiquement aux figures 3a,3b,3c, comprend des dentures coopérant avec des encoches.Furthermore, a means 34 is provided to ensure the rotational drive of the slide 14 by the rod 8. The latter means, shown schematically in Figures 3a, 3b, 3c comprises teeth cooperating with notches.

On pourrait également prévoir une liaison par des tenons glissant dans des rainures ou bien plus simplement prévoir un moyen de liaison assurant un frottement entre tige 8 et tiroir 14, par exemple des rondelles ressort.One could also provide a connection by pins sliding in grooves or more simply provide a connecting means ensuring a friction between rod 8 and slide 14, for example spring washers.

Ainsi après avoir poussé le tiroir 14, un opérateur situé à l'extérieur du véhicule peut donc faire pivoter ce tiroir pour assurer le maintien du verrou dans sa position déverrouillée.Thus, after pushing the drawer 14, an operator located outside the vehicle can therefore rotate the drawer to maintain the lock in its unlocked position.

Alternativement, il serait possible de prévoir sur l'extrémité du poussoir 29 un profil coopérant avec un profil complémentaire aménagé sur la tête 20b de l'axe de manoeuvre 8. Par exemple un poussoir 29 portant une extrémité 29a hexagonale ou carrée coopérant avec un trou hexagonal porté par la tête 20b. Une telle variante permet éventuellement d'omettre le moyen d'entraînement 34.Alternatively, it would be possible to provide on the end of the pusher 29 a profile cooperating with a complementary profile arranged on the head 20b of the operating shaft 8. For example a pusher 29 carrying a hexagonal or square end 29a cooperating with a hole hexagonal worn by the head 20b. Such a variant possibly makes it possible to omit the drive means 34.
