Description

La présente invention concerne d'une manière générale un verrou qui est actionné par un bouton tournant et qui peut être condamné par une clef.The present invention relates generally to a lock which is actuated by a rotary button and which can be locked by a key.

On connaît déjà des verrous du type général ci- dessus et qui équipent par exemple le panneau de fermeture du coffre à bagages de certains véhicule automobiles ou encore une porte quelconque. A cet égard on pourra se reporter par exemple au brevet américain N° 1 776 881 ou au brevet américain N° 3 019 632 qui décrivent chacun une poignée de porte à laquelle est associé un mécanisme actionnable par une clef permettant le verrouillage ou le déverrouillage de la poignée. Toutefois la liaision entre le mécanisme à clef et l'organe assurant le verrouillage ou non de la poignée est constituée par plusieurs éléments coopérantsde structure compliquée.Locks of the above general type are already known and which equip, for example, the closure panel of the luggage compartment of certain motor vehicles or even any door. In this regard, reference may be made, for example, to American patent No. 1,776,881 or to American patent No. 3,019,632, which each describe a door handle with which is associated a mechanism actuable by a key allowing the locking or unlocking of the handle. However, the connection between the key mechanism and the member ensuring the locking or not of the handle is constituted by several cooperating elements of complicated structure.

La présente invention a-donc pour but de remédier notamment à ces inconvénients en proposant un verrou perfectionné d'une conception mécanique particulièrement simple, fonctionnant d'une manière fiable.The object of the present invention is therefore to remedy these drawbacks in particular by proposing an improved lock with a particularly simple mechanical design, operating in a reliable manner.

A cet effet, l'invention a essentiellement pour objet un verrou actionnable par bouton tournant et pouvant être condamné par une clef, ce verrou comprenant essentiellement un corps muni d'un bouton tournant et renfermant un barillet et un organe de verrouillage tournant dans le corps suivant le même axe que celui du bouton dont la manoeuvre permet ou non l'actionnement de l'organe selon que le verrou est décondamné ou condamné par la clef coopérant avec le barillet, caractérisé en ce que la condamnation ou non du verrou obtenue respectivement par la déconnexion ou la connexion mutuelle à rotation de l'organe et du bouton est commandée par une platine indépendante disposée entre ces deux éléments et transversalement mobile à l'axe précité, laquelle platine comporte une première face comportant des moyens de butée coopérant avec un téton excentré solidaire du barillet et une deuxième face comportant des moyens formant came coopérant avec un élément intermédiaire solidaire en rotation de l'organe de verrouillage. Suivant une autre caractéristique, la platine indépendante précitée peut aussi être actionnée par une tringlerie et/ou oar un dispositif électromécanique de commande.To this end, the subject of the invention is essentially a lock operable by a rotary button and capable of being locked by a key, this lock essentially comprising a body provided with a rotary button and containing a barrel and a locking member rotating in the body. along the same axis as that of the button, the operation of which allows or not the actuation of the member depending on whether the lock is unlocked or locked by the key cooperating with the barrel, characterized in that the locking or not of the lock obtained respectively by the disconnection or the mutual connection in rotation of the member and of the button is controlled by an independent plate arranged between these two elements and transversely movable to the aforementioned axis, which plate has a first face comprising stop means cooperating with a stud eccentric integral with the barrel and a second face comprising means forming a cam cooperating with an intermediate element integral in rotation with the locking member. According to another characteristic, the above-mentioned independent plate can also be actuated by a linkage and / or by an electromechanical control device.

Ainsi, on pourra commander le verrou depuis l'intérieur du coffre à bagages d'un véhicule, ou bien encore depuis l'intérieur d'un volume adjacent. qui peut être celui de l'habitacle du véhicule.Thus, the lock can be controlled from inside the luggage compartment of a vehicle, or even from inside an adjacent volume. which may be that of the passenger compartment of the vehicle.

Suivant un mode de réalisation préféré, les moyens de butée de la première face de la platine sont constitués par deux flans parallèles entre lesquels se débat le téton du barillet pour commander le déplacement transversale de ladite platine sous l'effet de la rotation du barillet commandé par un premier type de clef.According to a preferred embodiment, the abutment means of the first face of the plate consist of two parallel blanks between which the pin of the barrel struggles to control the transverse movement of said plate under the effect of the rotation of the controlled barrel by a first type of key.

On notera encore ici qu'entre les deux flans précites, la première face de la platine comprend en outre un ergot ou analogue susceptible d'interdire la rotation du barillet lorsqu'il est commandé par un deuxième type de clef qui présente un supplément de longueur par rapport au premier type de clef précite.It will also be noted here that between the two aforementioned blanks, the first face of the plate further comprises a lug or the like capable of preventing rotation of the barrel when it is controlled by a second type of key which has an additional length compared to the first type of aforementioned key.

Selon une autre caractéristique de l'invention, les moyens formant came de la deuxième face de la platine sont constitués de préférence par une creusure pratiquée dans cette face et coopérant avec l'élément intermédiaire précité pour le rendre solidaire en rotation ou non du bouton tournant.According to another characteristic of the invention, the cam means of the second face of the plate preferably consist of a recess made in this face and cooperating with the above-mentioned intermediate element to make it integral in rotation or not with the rotary button .

Suivant encore une autre caractéristique de l'invention, l'élément intermédiaire est constitué par une coupelle munie sur une face d'un téton conique sollicité en permanence contre la deuxième face de la platine, et sur son autre face d'une tige montée axialement mobile dans l'organe de verrouillage précité.According to yet another characteristic of the invention, the intermediate element consists of a cup provided on one face with a conical stud permanently urged against the second face of the plate, and on its other face with an axially mounted rod movable in the aforementioned locking member.

Le verrou selon l'invention est encore caractérisé en ce qu'un ressort est enroulé sur la tige précitée et est monté entre le corps du verrou et la coupelle pour solliciter constamment cette dernière en position déconnectée de rotation avec le bouton.The lock according to the invention is further characterized in that a spring is wound on the aforementioned rod and is mounted between the body of the lock and the cup to constantly urge the latter in position disconnected from rotation with the button.

Suivant encore une autre caractéristique de l'invention, la connexion en rotation du bouton avec l'organe de verrouillage est assurée par le rebord de la coupelle précitée venant en prise avec le rebord d'une embase ou analogue solidaire du bouton tournant.According to yet another characteristic of the invention, the rotary connection of the button with the locking member is ensured by the rim of the aforementioned cup coming into engagement with the rim of a base or the like secured to the rotary button.

L'invention vise également un véhicule automobile équipé d'au moins un verrou répondant à l'une ou l'autre des caractéristiques susmentionnées.The invention also relates to a motor vehicle equipped with at least one lock meeting one or the other of the above characteristics.

Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés à titre d'exemple uniquement, et dans lesquels:

  • La figure 1 est une vue de côté et en coupe longitudinale d'un verrou suivant l'invention en position décondamnée.
  • La figure 2 est une vue en coupe du verrou de la figure 1, faite suivant la ligne II-II de cette figure.
  • La figure 3 est une vue identique à la figure 2, sauf qu'elle montre le verrou en position condamnée.

  • La figure 5 est une vue en coupe faite suivant la ligne V-V de la figure 3 et montrant la position de la platine lorsque le verrou est condamné.
  • La figure 6 est une vue partielle en perspective montrant la platine coopérant avec une clef,-dite de service et interdisant la décondamnation du verrou; et
  • La figure 7 est une vue extérieure du bouton tournant suivant la flèche VII de la figure 1.
However, other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings, given by way of example only, and in which:
  • Figure 1 is a side view in longitudinal section of a lock according to the invention in the unlocked position.
  • Figure 2 is a sectional view of the lock of Figure 1, taken along line II-II of this figure.
  • Figure 3 is a view identical to Figure 2, except that it shows the latch in the locked position.
  • Figure 4 is a sectional view taken along the line IV-IV of Figure 2 and showing more particularly the position of the plate when the lock is unlocked.
  • Figure 5 is a sectional view taken along line VV of Figure 3 and showing the position of the plate when the lock is locked.
  • Figure 6 is a partial perspective view showing the plate cooperating with a key, said service and prohibiting unlocking of the lock; and
  • FIG. 7 is an external view of the rotary button according to arrow VII of FIG. 1.

Suivant un exemple de réalisation, et en se reportant aux dessins annexés, un verrou conforme à l'invention comprend essentiellement un corps 1 sur et dans lequel est monté un bouton tournant 2, et qui renferme essentiellement trois éléments et à savoir un barillet 3, un organe de verrouillage 4 et une pièce indépendante 5 qui est interposée entre le barillet 3 et l'organe de verrouillage 4, et qui présente la forme générale d'un coulisseau ou d'une platine susceptible de se déplacer transversalement à l'axe X-X' de rotation du barillet 3 et de l'organe de verrouillage 4.According to an exemplary embodiment, and with reference to the accompanying drawings, a lock according to the invention essentially comprises a body 1 on and in which a button is mounted rotating 2, and which essentially contains three elements and namely a barrel 3, a locking member 4 and an independent part 5 which is interposed between the barrel 3 and the locking member 4, and which has the general shape of a slide or a plate capable of moving transversely to the axis XX 'of rotation of the barrel 3 and of the locking member 4.

Le corps de verrou 1 peut être fixé sur le panneau 6 d'accès à un volume, qui peut être par exemple celui du coffre à bagages d'un véhicule, cette fixation étant assurée par l'intermédiaire d'un clips où analogue 7 et d'un joint d'étanchéité 8.The lock body 1 can be fixed on the panel 6 for access to a volume, which can for example be that of the luggage compartment of a vehicle, this fixing being ensured by means of a clip where the like 7 and a seal 8.

Le barillet 3 comporte sur sa face 9 en regard de la platine 5 un téton excentré 10 qui, sous l'effet de la rotation d'une clef 11 introduite dans ledit barillet, permet le déplacement transversal de la platine 5 en vue de condamner ou de décondamner le verrou, comme on l'expliquera plus loin.The barrel 3 has on its face 9 opposite the plate 5 an eccentric stud 10 which, under the effect of the rotation of a key 11 introduced into said barrel, allows the transverse movement of the plate 5 in order to lock or unlock the lock, as explained below.

Comme on l'a montré schématiquement en 12 sur les figures 2 à 5, le coulissement transversal de la platine 5 peut être commandé par une tringlerie et/ou encore par un dispositif électromécanique de commande.As shown schematically at 12 in Figures 2 to 5, the transverse sliding of the plate 5 can be controlled by a linkage and / or by an electromechanical control device.

Ainsi, dans le cas du coffre à bagages d'un véhicule automobile, on peut commander la platine 5 depuis l'intérieur du coffre préalablement rendu accessible ou encore depuis l'intérieur de l'habitacle du véhicule.Thus, in the case of the luggage compartment of a motor vehicle, the plate 5 can be controlled from the interior of the trunk previously made accessible or even from the interior of the passenger compartment of the vehicle.

Comme on le voit bien sur les figures 4 à 6, la platine ou coulisseau 5 possède une première face 5a, en regard de la face 9 du barillet 3, laquelle première face comporte deux butées ou flans parallèles 13,14, entre lesquels se débat le téton 10 du barillet 3 pour commander le déplacement transversal de la platine 5 sous l'effet de la rotation du barillet commandé par un premier type de clef 11 visible sur la figure 1. Entre les deux butées parallèles 13 et 14, la première face 5a de la platine 5 comprend en outre un ergot 15 susceptible d'interdire la rotation du barillet 3 lorsque celui-ci est commandé par un deuxième type de clef que l'on a montré partiellement en 16 sur la figure 6. On expliquera plus loin comment la rotation du barillet 3 est interdite lorsqu'on utilise la clef 16, et on dira simplement ici que la clef 16 présente un supplément de longueur 16a (figure 6) par rapport à la clef 11.As can be seen in Figures 4 to 6, the plate or slide 5 has a first face 5a, opposite the face 9 of the barrel 3, which first face has two stops or parallel blanks 13,14, between which is struggling the stud 10 of the barrel 3 for controlling the transverse movement of the plate 5 under the effect of the rotation of the barrel controlled by a first type of key 11 visible in FIG. 1. Between the two parallel stops 13 and 14, the first face 5a of the plate 5 further comprises a lug 15 capable of prohibiting the rotation of the barrel 3 when the latter is controlled by a second type of key which has been shown partially at 16 in FIG. 6. We will explain below how the rotation of the barrel 3 is prohibited when the key 16 is used, and it will simply be said here that the key 16 has an additional length 16a (FIG. 6) relative to the key 11.

L'autre face ou deuxième face 5b de la platine 5 comporte un moyen formant came, tel que par exemple une creusure 17 pratiquée dans ladite face, comme on le voit sur les figures 2 à 5. Cette creusure 17 coopère avec un élément intermédiaire 18 qui est solidaire en rotation de l'organe de verrouillage 4 et que l'on décrira maintenant en détail.The other face or second face 5b of the plate 5 comprises a means forming a cam, such as for example a recess 17 formed in said face, as can be seen in FIGS. 2 to 5. This recess 17 cooperates with an intermediate element 18 which is integral in rotation with the locking member 4 and which will now be described in detail.

Cet élément intermédiaire 18 est constitué par une coupelle 19 munie sur une face d'un téton conique ou analogue 20 susceptible de coopérer avec la creusure 17, par le fait que la coupelle 19 est sollicitée en permanence contre la deuxième face 5b de la platine 5 grâce à un ressort 21. On pourrait très bien, sans sortir du cadre de l'invention, prévoir la creusure 17 sur la coupelle 19 et le téton 20 sur la face 5b de la platine 5, ce qui ne changerait rien au fonctionnement.This intermediate element 18 is constituted by a cup 19 provided on one face with a conical stud or the like 20 capable of cooperating with the recess 17, by the fact that the cup 19 is permanently urged against the second face 5b of the plate 5 thanks to a spring 21. It could very well, without departing from the scope of the invention, provide the recess 17 on the cup 19 and the stud 20 on the face 5b of the plate 5, which would not change anything in operation.

Sur son autre face, la coupelle 19 est munie d'une tige 22 montée axialement mobile dans un alésage 23 de l'organe de verrouillage 4 étant entendu, comme on l'a dit précédemment, que la tige 22 est solidaire en rotation dudit organe de verrouillage 4. Comme on le voit bien sur les figures 1 à 3, le ressort 21 est enroulé sur la tige 22 et est monté par ses deux extrémités entre le corps de verrou (comme on le voit en 24 sur la figure 3) et la coupelle 19 (comme on le voit en 25 sur la figure 1).On its other face, the cup 19 is provided with a rod 22 mounted axially movable in a bore 23 of the locking member 4 being understood, as has been said previously, that the rod 22 is integral in rotation with said member locking 4. As can be seen in FIGS. 1 to 3, the spring 21 is wound on the rod 22 and is mounted at its two ends between the lock body (as seen at 24 in FIG. 3) and the cup 19 (as seen in 25 in Figure 1).

Ainsi, comme on le comprend le ressort 21 travaille non seulement en compression axiale mais a également une fonction de rappel en rotation de l'organe de verrouillage 4, et du bouton 2, comme on l'expliquera plus loin.Thus, as can be understood, the spring 21 works not only in axial compression but also has a function of return in rotation of the locking member 4, and of the button 2, as will be explained below.

La connexion en rotation du bouton 2 avec l'organe de verrouillage 4 est assurée par le rebord 19a de la coupelle 19 qui vient en prise avec le rebord 26a d'une embase ou analogue 26 solidaire en rotation du bouton tournant 2, comme on le voit en 27 sur la figure 1. Comme on le comprend, le bouton tournant 2 et l'organe de verrouillage 4 seront solidaires en rotation par l'intermédiaire de la coupelle 19 lorsque le téton conique 20 ne se trouve pas logé dans la creusure 17 de la platine 5 (voir figures 1 et 2). Par contre, lorsque le téton conique 20 sera logé dans la creusure 17 (figure 3), on se trouvera en position débrayée, puisque les rebords 19a et 26a de la coupelle 19 et de l'embase 26 ne sont plus en prise, et le bouton 2 ne pourra plus entraîner en rotation l'organe de verrouillage 4.The connection in rotation of the button 2 with the locking member 4 is ensured by the rim 19a of the cup 19 which comes into engagement with the rim 26a of a base or the like 26 integral in rotation with the rotary button 2, as is can be seen at 27 in FIG. 1. As can be understood, the rotary button 2 and the locking member 4 will be integral in rotation by means of the cup 19 when the conical stud 20 is not housed in the recess 17 of plate 5 (see Figures 1 and 2). On the other hand, when the conical stud 20 is housed in the recess 17 (FIG. 3), we will be in the disengaged position, since the edges 19a and 26a of the cup 19 and of the base 26 are no longer in engagement, and the button 2 can no longer rotate the locking member 4.

On a montré en 28 un ressort de rappel du barillet 3, lequel ressort entoure le barillet et est maintenu par un manchon fixe 29 formant entretoise de verrou.A return spring of the barrel 3 has been shown at 28, which spring surrounds the barrel and is held by a fixed sleeve 29 forming a lock spacer.

On décrira maintenant. le fonctionnement du verrou à bouton tournant selon l'invention en se reportant plus particulièrement aux figures 4, 5 et 7.We will describe now. the operation of the rotary button lock according to the invention with particular reference to FIGS. 4, 5 and 7.

On partira de la position décondamnée du verrou visible sur les figures 1 et 2. Dans cette position, la rotation du bouton 2 suivant la flèche F1 de la figure 7 provoquera, comme on l'a dit plus haut, la rotation de l'organe de verrouillage 4 qui pourra ainsi actionner une serrure non représentée. Autrement dit, on pourra ainsi et par exemple ouvrir et fermer le coffre d'un véhicule en agissant sur le bouton 2 étant bien entendu que celui-ci reprendra toujours sa position initiale grâce au ressort de rappel 21 fonctionnant en rappel de rotation comme on l'a expliqué precédemment.We will start from the unlocked position of the bolt visible in Figures 1 and 2. In this position, the rotation of the button 2 along the arrow F 1 of Figure 7 will cause, as we said above, the rotation of the locking member 4 which can thus actuate a lock not shown. In other words, it will thus be possible and for example to open and close the boot of a vehicle by acting on the button 2, it being understood that the latter will always return to its initial position thanks to the return spring 21 operating in rotation return as in the case of explained previously.

Pour condamner le verrou, il suffit de déplacer la platine 5, ce qui peut être fait à l'aide de la clef maîtresse 11 ou par action interne à partir du coffre en appuyant en 30, ou encore à partir du poste de conduite du véhicule, par une télécommande non représentée et actionnant la tringlerie 12. Si l'on utilise la clef 11, on comprend qu'une rotation de la clef suivant la flèche F1 de la figure 7 provoquera une rotation correspondante du barillet 3 et du téton excentré 10 qui, en prenant appui sur la butée 14, comme on le voit sur la figure 6, déplacera la platine 5 qui prendra la position visible sur la figure 5. Il est à noter ici qu'en relâchant la clef, celle-ci sera rappelée dans sa position initiale verticale grâce au ressort 28. Autrement dit, comme on le voit sur la figure 5, après que le coulisseau 5 ait été déplacé le téton 10 du barillet passera automatiquement de la position 10a à la position 10 grâce au ressort de rappel 28. Dans une telle position du coulisseau 5, le téton 20 de la coupelle 19 penêtrera dans la creusure 17 du coulisseau 5 sous l'effet du ressort 21, de sorte que la coupelle 19 sera dégagée de l'embase 26 solidaire du bouton tournant 2. Autrement dit, la rotation de ce bouton sera sans effet sur l'organe de verrouillage 4 qui est débrayé. C'est dire que le verrou est condamné, le rebord 19a étant dégagé du rebord 26a. Pour décondamner le verrou, il suffit de tourner la clef 11 dans le sens inverse F2 à celui de la flèche F, sur la figure 7. Ainsi, le téton 10 se trouvant dans la position en traits pleins représentés sur la figure 5, agira sur la butée 13, de sorte que le coulisseau prendra la position visible sur la figure 4 ou encore sur les figures 1 et 2. Dans cette position, le téton 20 de la coupelle 19 est sorti de la creusure 17 du coulisseau 5, ce qui réalise comme on le comprend l'embrayage de l'organe de verrouillage 4 avec le bouton de manoeuvre 2. Comme on le voit sur la figure 4, après relâchement de la clef 11, c'est-àdire après avoir décondamné le verrou, le téton passe automatiquement de la position 10b à la position 10 grâce au ressort de rappel 28. Ainsi, le téton 10 se trouve dans une position prête à effectuer une nouvelle condamnation du verrou par action sur la butée 14, comme on l'a expliqué précédemment.To lock the lock, simply move the plate 5, which can be done using the master key 11 or by internal action from the trunk by pressing 30, or from the vehicle operator station , by a remote control not shown and actuating the linkage 12. If the key 11 is used, it is understood that a rotation of the key according to the arrow F 1 in FIG. 7 will cause a corresponding rotation of the barrel 3 and of the eccentric stud 10 which, by bearing on the stop 14, as seen in Figure 6, will move the plate 5 which will take the position visible in Figure 5. It should be noted here that by releasing the key, it will be returned to its original vertical position by the spring 28. In other words, as can be seen in FIG. 5, after the slider 5 has been moved the stud 10 of the barrel will automatically pass from position 10a to position 10 thanks to the return spring 28. In such a position of the slider 5, the pin 20 of the cup 19 will enter the recess 17 of the slide 5 under the effect of the spring 21, so that the cup 19 will be released from the base 26 secured to the rotary button 2. In other words, the rotation of this button will have no effect on the locking member 4 which is d clipped. This means that the lock is locked, the rim 19a being released from the rim 26a. To unlock the lock, simply turn the key 11 in the opposite direction F 2 to that of the arrow F, in Figure 7. Thus, the stud 10 in the position in solid lines shown in Figure 5, will act on the stop 13, so that the slide will take the position visible in FIG. 4 or again in FIGS. 1 and 2. In this position, the stud 20 of the cup 19 has come out of the recess 17 of the slide 5, which realizes as is understood the clutch of the locking member 4 with the operating button 2. As seen in Figure 4, after releasing the key 11, that is to say after unlocking the lock, the nipple automatically moves from position 10b to position 10 thanks to the return spring 28. Thus, the nipple 10 is in a position ready to effect a new locking of the latch by action on the stop 14, as explained previously .

On ajoutera encore ici que lorsque l'organe de verouillage 4 est en position embrayée comme on le voit sur les figures 1 et 2, le ressort 21, après actionnement du bouton 2, rappellera toujours ce dernier par l'intermédiaire de la coupelle 19 et de l'embase 26. Ce ressort egaleinent, comme on l'a dit plus haut, exerce un effort axial pour déconnecter la coupelle 19 de l'embase 26 lorsque le coulisseau 5 le permet.It will also be added here that when the locking member 4 is in the engaged position as seen in FIGS. 1 and 2, the spring 21, after actuation of the button 2, will always recall the latter via the cup 19 and of the base 26. This equal spring, as said above, exerts an axial force to disconnect the cup 19 from the base 26 when the slider 5 allows it.

Le verrou selon l'invention fonctionne avec une clef 11, appelée clef maîtresse, mais il ne peut pas fonctionner avec la clef 16 visible sur la figure 6 et que l'on peut appeler clef de service. En effet, comme on le voit sur la figure 6, le supplément de longueur 16a de la clef 16 fait que, lorsqu'on veut tourner cette clef, elle ne peut exercer aucune action sur la butée 13 puisqu'en tournant, elle se coincera entre ladite butée et l'ergot 15. Ainsi, lorsque l'on veut confier son véhicule à un tiers, tel que par exemple un garagiste, on pourra lui remettre la clef de service 16 qui lui permettra d'avoir accès à toutes les parties du véhicule sauf au coffre à bagages.The lock according to the invention operates with a key 11, called the master key, but it cannot operate with the key 16 visible in FIG. 6 and which can be called the service key. In fact, as can be seen in FIG. 6, the additional length 16a of the key 16 means that, when we want to turn this key, it cannot exert any action on the stop 13 since, when it turns, it will get stuck between said stop and the lug 15. Thus, when one wishes to entrust his vehicle to a third party, such as for example a garage owner, one can give him the service key 16 which will allow him to have access to all the parts of the vehicle except in the luggage compartment.

On a donc réalisé suivant l'invention un verrou à bouton tournant d'une grande fiabilité en raison de la simplicité de sa conception mécanique qui réside essentiellement dans la prévision d'une petite platine indépendante coopérant avec une coupelle et dont le déplacement transversal autorise ou non la rotation de l'organe de verrouillage commandant la serrure.There was therefore produced according to the invention a rotary button lock of great reliability due to the simplicity of its mechanical design which essentially lies in the provision of a small independent plate cooperating with a cup and whose transverse movement allows or not the rotation of the locking member controlling the lock.
