Description

La présente invention concerne un ensemble verrou-serrure notamment pour un ouvrant de véhicule automobile, telle qu'une portière, un hayon, une lunette de hayon ou le coffre d'un véhicule automobile.The present invention relates to a lock-lock assembly especially for a motor vehicle door, such as a door, a tailgate, a tailgate bezel or trunk of a motor vehicle.

Un véhicule est généralement équipé d'une serrure et d'un verrou montés dans la porte du véhicule. Le verrou permet le verrouillage et le déverrouillage de la porte au moyen d'une clé et la serrure permet la condamnation/décondamnation de la porte. Plus précisément, le verrou comporte un rotor, déplaçable en rotation par la clé et solidaire d'une biellette appelée batteuse. Le document GB 2 164 697 décrit un exemple de verrou relié à un élément de transmission. La « batteuse menée » entraîne un élément de transmission, tel qu'une tringle ou un câble, pour actionner un mécanisme de la serrure. La serrure peut également comporter en entrée une deuxième batteuse, appelée « batteuse menant », entraînée par l'élément de transmission, et qui actionne un élément à l'entrée de la serrure pour la condamnation/décondamnation de la porte.A vehicle is usually equipped with a lock and a lock mounted in the door of the vehicle. The lock allows the locking and unlocking of the door by means of a key and the lock allows the locking / unlocking of the door. More specifically, the lock comprises a rotor, movable in rotation by the key and secured to a rod called thresher. The document GB 2,164,697 describes an example of a latch connected to a transmission element. The "driven thresher" drives a transmission element, such as a rod or a cable, to actuate a mechanism of the lock. The lock may also include as input a second threshing machine, called "leading thresher", driven by the transmission element, and which actuates an element at the entrance of the lock for the condemnation / unlocking of the door.

Le débattement angulaire de la clé et le couple qui lui est appliqué pour l'actionner se retrouvent ensuite au niveau des éléments participant à la transmission de mouvement jusqu'à l'entrée de la serrure.The angular movement of the key and the torque applied to it to operate are then found at the elements involved in the transmission of movement to the entrance of the lock.

Par « débattement angulaire », on entend ici l'angle de rotation formé entre la position initiale d'une pièce mobile en rotation et la position finale après que ladite pièce a effectué la rotation.By "angular displacement" is meant here the angle of rotation formed between the initial position of a rotating moving part and the final position after said part has made the rotation.

Pour certains modèles de véhicule, des débattements angulaires importants sont demandés notamment pour la clé (de l'ordre de +/-80°) et/ou pour l'élément de serrure en entrée de serrure (+/-70°). Toutefois l'environnement intérieur de la porte est limité. Il peut s'avérer difficile, voire impossible de réaliser complètement la course angulaire des batteuses, sans éviter que celles-ci n'entrent en collision avec des éléments présents dans cet environnement intérieur.For certain vehicle models, large angular deflections are required, in particular for the key (of the order of +/- 80 °) and / or for the lock element at the entry of the lock (+/- 70 °). However, the interior environment of the door is limited. It may be difficult, if not impossible, to complete the angular stroke of the threshing machines, without preventing them from colliding with elements present in this indoor environment.

A cet effet, l'invention a pour objet un ensemble verrou-serrure de véhicule selon la revendication 1.For this purpose, the subject of the invention is a vehicle lock-and-lock assembly according to claim 1.

Selon une ou plusieurs caractéristiques de l'ensemble verrou-serrure,

  • il comporte un support de guide interposé entre l'axe et la couronne, ledit support de guide comportant un orifice central pour le passage de l'axe et un ergot excentré pour le pignon satellite, le pignon satellite étant en liaison pivot avec l'ergot de sorte que le pivotement du pignon satellite soit guidé par l'ergot,
  • l'axe est menant, la batteuse est menée et le mécanisme adaptateur de course est configuré pour être entraîné en pivotement par ledit axe menant et pour entraîner ladite batteuse menée en diminuant le débattement angulaire de la batteuse menée par rapport au débattement angulaire de l'axe menant,
  • l'axe est mené, la batteuse est menante et le mécanisme adaptateur de course est configuré pour être entraîné en pivotement par ladite batteuse menant et pour entraîner ledit axe mené en augmentant le débattement angulaire de la batteuse menant par rapport au débattement angulaire de l'axe mené,
  • le rayon de la denture R1 du pignon satellite, le rayon de la denture R2 de la roue dentée et le rayon R3 de la couronne satisfont la relation : R3 > R2 et R3 > R1,
  • le rayon R3 de la couronne est sensiblement égal à 2*R1+R2, avec R1, le rayon de la denture du pignon satellite et R2, le rayon de la denture de la roue dentée.
According to one or more features of the lock-lock assembly,
  • it comprises a guide support interposed between the axis and the crown, said guide support having a central orifice for the passage of the axis and an eccentric pin for the planet pinion, the planet pinion being in pivot connection with the pin so that the pivoting of the satellite pinion is guided by the pin,
  • the axis is driving, the threshing machine is driven and the stroke adapter mechanism is configured to be pivotally driven by said drive shaft and to drive said driven thresher by decreasing the angular movement of the driven thresher relative to the angular movement of the leading axis,
  • the axle is driven, the thresher is driving and the stroke adapter mechanism is configured to be pivoted by said leading thresher and to drive said driven shaft by increasing the angular movement of the leading thresher relative to the angular travel of the led axis,
  • the radius of the toothing R1 of the planet gear, the radius of the teeth R2 of the toothed wheel and the radius R3 of the crown satisfy the relation: R3> R2 and R3> R1,
  • the radius R3 of the ring is substantially equal to 2 * R1 + R2, with R1, the radius of the toothing of the planet pinion and R2, the radius of the toothing of the toothed wheel.

En disposant un organe de liaison en sortie de verrou, on peut diminuer le débattement angulaire de la batteuse menée par rapport à la course angulaire de l'axe menant grâce à un mécanisme adaptateur de course intégré, c'est-à-dire présentant un encombrement limité, sensiblement équivalent à l'encombrement d'une batteuse seule classique qui serait directement solidaire de l'axe menant.By arranging a link member at the bolt output, it is possible to reduce the angular displacement of the driven thresher with respect to the angular travel of the driving axis by virtue of an integrated stroke adapter mechanism, that is to say having a limited space, substantially equivalent to the size of a conventional single thresher that would be directly attached to the driving axis.

Par exemple, avec un mécanisme adaptateur de course de coefficient deux, on peut réduire un débattement de l'ordre de +/-70° au niveau de la clé à un débattement de l'ordre de +/-35° sur la batteuse menée en sortie de verrou.For example, with a two-stage travel adapter mechanism, a clearance of +/- 70 ° at the key can be reduced to a clearance of +/- 35 ° on the driven threshing machine. at the exit of the lock.

Ainsi, l'utilisation d'un mécanisme adaptateur de course en sortie de verrou permet de conserver un débattement angulaire important au niveau de la clé en évitant d'entrer en collision avec des éléments présent dans l'environnement proche de la batteuse menée.Thus, the use of a travel adapter mechanism at the exit of the lock makes it possible to maintain a large angular clearance at the key by avoiding colliding with elements present in the environment close to the driven threshing machine.

Par ailleurs, le couple transmis est augmenté dans les mêmes proportions.Moreover, the transmitted torque is increased in the same proportions.

Egalement, en disposant un organe de liaison en entrée de serrure, on peut augmenter le débattement angulaire de l'axe mené par rapport à la course angulaire de la batteuse menant. Par ailleurs, le couple transmis est réduit dans les mêmes proportions entre la batteuse menant et l'axe mené.Also, by arranging a connection member lock entry, it can increase the angular displacement of the driven axis relative to the angular travel of the leading thresher. Furthermore, the transmitted torque is reduced in the same proportions between the leading thresher and the driven axis.

L'utilisation d'un mécanisme adaptateur de course en entrée de serrure permet de conserver le débattement angulaire de l'élément de la serrure avec un débattement angulaire plus petit au niveau de la batteuse menant, évitant à cette dernière d'entrer en collision avec des éléments présent dans son environnement proche. Par ailleurs, le couple transmis est réduit dans les mêmes proportions entre la batteuse menant et l'axe mené.The use of a stroke input adapter mechanism locks the angular movement of the lock member with a smaller angular movement at the leading thresher, preventing it from colliding with elements present in its immediate environment. Furthermore, the transmitted torque is reduced in the same proportions between the leading thresher and the driven axis.

Enfin en disposant deux organes de liaison, un premier en sortie du verrou et un deuxième en entrée de serrure, et en choisissant judicieusement les rapports des mécanismes adaptateurs de course, il est possible de modifier les débattements angulaires et les couples exercés d'une part en entrée de serrure et d'autre part en sortie de verrou.Finally, by arranging two connecting members, one at the output of the latch and a second at the lock input, and judiciously choosing the ratios of the stroke adapter mechanisms, it is possible to modify the angular displacements and the torques exerted on the one hand. at the entrance of the lock and secondly at the exit of the lock.

Par exemple, en choisissant des mécanismes adaptateurs de course de même coefficient, on réduit le débattement angulaire de la batteuse menée au niveau de la sortie du verrou et on raugmente le débattement angulaire au niveau de l'axe mené. Les débattements au niveau du verrou et de la serrure sont conservés tandis que des débattements angulaires intermédiaires plus petits permettent d'être transmis du verrou à la serrure sans risquer d'entrer en collision avec les éléments présents dans l'environnement intérieur de la porte. De plus, un même mécanisme adaptateur de course peut ainsi être utilisé.For example, by choosing race adapter mechanisms of the same coefficient, it reduces the angular movement of the thresher conducted at the output of the lock and increases the angular displacement at the driven axis. Lock and lock deflections are maintained while smaller intermediate angular deflections can be transmitted from the lock to the lock without the risk of colliding with the elements in the interior environment of the door. In addition, the same stroke adapter mechanism can thus be used.

For a better understanding of the invention, only the elements involved in the invention have been represented.

La figure 1 représente un ensemble verrou-serrure monté dans une porte de véhicule, tel qu'un véhicule automobile. L'ensemble verrou-serrure comporte un verrou 2 et une serrure 3 déportée, le verrou 2 et la serrure 3 étant reliés par un élément de transmission 9 tel qu'une tringle ou un câble.The figure 1 represents a lock-lock assembly mounted in a vehicle door, such as a motor vehicle. The lock-lock assembly comprises a lock 2 and a remote lock 3, the lock 2 and the lock 3 being connected by a transmission element 9 such as a rod or a cable.

On the side of the lock 3, the rotation of a driven shaft 7 makes it possible to actuate an element of the lock for locking / unlocking the door ( figures 5 and 6 ).

Selon un premier exemple de réalisation illustré sur les figures 2 à 4, l'ensemble verrou-serrure de véhicule comporte un organe de liaison 4 comprenant une batteuse menée 8 à la sortie du verrou 2 et un mécanisme adaptateur de course interposé entre l'axe menant 6 et la batteuse menée 8.According to a first embodiment illustrated on the Figures 2 to 4 , the vehicle lock-lock assembly comprises a connecting member 4 comprising a driven thresher 8 at the exit of the lock 2 and a race adapter mechanism interposed between the driving shaft 6 and the driven thresher 8.

La batteuse menée 8 est configurée pour pivoter autour de l'axe menant 6, solidaire du rotor de verrou 2 et est apte à être reliée à un élément de transmission 9. La batteuse menée 8 présente une forme sensiblement en disque avec une excroissance formant une extrémité 8a présentant par exemple un trou pour fixer une première extrémité de l'élément de transmission 9. Dans ce premier exemple, la deuxième extrémité de l'élément de transmission 9 est reliée à un élément de la serrure (tel qu'un cardan ou une batteuse).The driven thresher 8 is configured to pivot about the driving axis 6, integral with the lock rotor 2 and is adapted to be connected to a transmission element 9. The driven thresher 8 has a substantially disk-like shape with a protrusion forming a end 8a having for example a hole for fixing a first end of the transmission element 9. In this first example, the second end of the transmission element 9 is connected to an element of the lock (such as a cardan or a thresher).

Le mécanisme adaptateur de course est configuré pour augmenter ou réduire le débattement angulaire de l'axe menant 6 par rapport au débattement angulaire de la batteuse menée 8. Pour cela, le mécanisme adaptateur de course comporte par exemple un train d'engrenage apte à engrener d'une part avec ledit axe 6 et d'autre part avec ladite batteuse 8.The stroke adapter mechanism is configured to increase or reduce the angular displacement of the driving shaft 6 relative to the angular displacement of the driven thresher 8. For this, the race adapter mechanism comprises for example a gear train adapted to mesh on the one hand with said axis 6 and on the other hand with said thresher 8.

Dans ce premier exemple et mieux visible sur les figures 2 et 3 qui représentent une vue agrandie de l'organe de liaison 4, le mécanisme adaptateur de course 11 est configuré pour être entraîné en pivotement par l'axe menant 6 et pour entraîner la batteuse menée 8 de manière à diminuer le débattement angulaire de la batteuse menée 8 par rapport au débattement angulaire de l'axe menant 6.In this first example and better visible on Figures 2 and 3 which represent an enlarged view of the connecting member 4, the stroke adapter mechanism 11 is configured to be pivotally driven by the driving shaft 6 and to drive the driven thresher 8 so as to reduce the angular displacement of the driven thresher 8 with respect to the angular displacement of the driving shaft 6.

Le mécanisme adaptateur de course 11 comporte une roue dentée 15 coaxiale et solidaire de l'axe menant 6, un pignon satellite 14 engrenant la roue dentée 15 et une couronne 12 coaxiale à l'axe menant 6 et solidaire de la batteuse menée 8, ladite couronne 12 présentant une denture périphérique interne 13 engrenant le pignon satellite 14.The stroke adapter mechanism 11 comprises a gearwheel 15 coaxial and integral with the driving spindle 6, a sun gear 14 meshing with the toothed wheel 15 and a ring 12 coaxial with the driving shaft 6 and integral with the driven thresher 8, said crown 12 having an internal peripheral gearing 13 meshing with the planet gear 14.

La roue dentée 15 est solidaire de l'axe menant 6. Pour cela, la roue dentée 15 présente un orifice central 15a pour le passage de l'axe menant 6, l'axe menant 6 étant fixé dans l'orifice central 15a par tout moyen approprié, tel que par l'assemblage d'une clavette de l'élément de liaison 4.The toothed wheel 15 is integral with the driving shaft 6. For this, the toothed wheel 15 has a central orifice 15a for the passage of the driving shaft 6, the driving shaft 6 being fixed in the central orifice 15a by any appropriate means, such as by assembling a key of the connecting element 4.

La roue dentée 15 est coaxiale à l'axe menant 6 et la couronne 12 est solidaire de la batteuse menée 8, c'est-à-dire que les axes de rotation A-A de la roue dentée 15, de l'axe menant 6 et de la batteuse menée 8 sont confondus.The toothed wheel 15 is coaxial with the driving axis 6 and the crown 12 is integral with the driven thresher 8, that is to say that the axes of rotation AA of the toothed wheel 15, the driving shaft 6 and of the driven thresher 8 are merged.

On prévoit que la batteuse menée 8 soit en liaison pivot avec l'axe menant 6 de sorte que le pivotement de la batteuse menée 8 soit guidé par l'axe menant 6.It is expected that the driven thresher 8 is in pivot connection with the driving axis 6 so that the pivoting of the driven thresher 8 is guided by the driving shaft 6.

L'organe de liaison 4 comporte en outre un support de guide 17, fixé au stator de verrou, interposé entre l'axe menant 6 et la couronne 12. Le support de guide 17 en forme de disque, comporte un orifice central 17a pour le passage de l'axe menant 6 et un ergot 17b excentré saillant vers le pignon satellite 14. Le pignon satellite 14 est en liaison pivot avec l'ergot 17b de sorte que le pivotement du pignon satellite 14 soit guidé par l'ergot 17b.The connecting member 4 further comprises a guide support 17, fixed to the latch stator, interposed between the driving shaft 6 and the crown 12. The disc-shaped guide support 17 has a central orifice 17a for the passage of the driving shaft 6 and an eccentric pin 17b protruding towards the pinion satellite 14. The pinion 14 is pivotally connected to the pin 17b so that the pivoting of the pinion 14 is guided by the pin 17b.

Le rayon de la denture R1 du pignon satellite 14, le rayon de la denture R2 de la roue dentée 15 et le rayon R3 de la couronne 12 satisfont la relation : R3 > R2 et R3 > R1 (figure 4).The radius of the toothing R1 of the planet pinion 14, the radius of the toothing R2 of the toothed wheel 15 and the radius R3 of the crown 12 satisfy the relation: R3> R2 and R3> R1 ( figure 4 ).

Le facteur de réduction obtenu par le mécanisme adaptateur de course 11 est égal au diamètre de la roue dentée 15 divisé par le diamètre de la couronne 12.The reduction factor obtained by the travel adapter mechanism 11 is equal to the diameter of the toothed wheel 15 divided by the diameter of the crown 12.

Par exemple, pour diviser par deux le débattement angulaire de l'axe menant 6 par rapport au débattement angulaire de la batteuse menée 8, le rayon de la denture périphérique interne R3 de la couronne 12 est sensiblement égal à 2*R1+R2 avec R1, le rayon de la denture du pignon satellite 14 et R2, le rayon de la denture de la roue denté 15.For example, to divide by two the angular displacement of the driving axis 6 with respect to the angular displacement of the driven thresher 8, the radius of the internal peripheral gear R3 of the 12 is substantially equal to 2 * R1 + R2 with R1, the radius of the toothing of the planet pinion 14 and R2, the radius of the toothing of the toothed wheel 15.

En fonctionnement comme on peut le voir sur la figure 4, en pivotant dans le sens horaire, l'axe menant 6 solidaire de la roue dentée 15 fait pivoter cette dernière dans le sens horaire (flèche F1). Le pignon satellite 14 qui engrène la roue dentée 15 pivote alors dans le sens antihoraire (flèche F2) autour de l'ergot 17b. La couronne 12 qui engrène le pignon satellite 14 pivote alors dans le sens antihoraire (flèche F3) guidée en rotation par l'axe menant 6, entraînant dans le même sens la batteuse menée 8 solidaire de couronne 12.In operation as can be seen on the figure 4 , by pivoting in the clockwise direction, the drive shaft 6 secured to the toothed wheel 15 rotates the latter clockwise (arrow F1). The planet gear 14 which meshes with the toothed wheel 15 then pivots counterclockwise (arrow F2) around the lug 17b. The ring gear 12 which meshes the planet pinion 14 then pivots counterclockwise (arrow F3) guided in rotation by the driving shaft 6, driving in the same direction the driven thresher 8 secured to the ring 12.

Le débattement angulaire de la batteuse menée 8 est donc réduit (par un coefficient deux dans cet exemple) par rapport à la course angulaire de l'axe menant 6 tout en étant intégré, c'est-à-dire en présentant un encombrement limité, sensiblement équivalent à l'encombrement d'une batteuse seule classique.The angular displacement of the driven thresher 8 is therefore reduced (by a coefficient of two in this example) with respect to the angular travel of the driving axis 6 while being integrated, that is to say having a limited space requirement, substantially equivalent to the size of a conventional single thresher.

Par exemple, avec un mécanisme adaptateur de course de coefficient deux, on peut réduire un débattement de l'ordre de +/-70° au niveau de la clé et réaliser un débattement de l'ordre de +/-35° sur la batteuse menée 8 et donc sur l'axe mené 7 en entrée de serrure.For example, with a two-stage travel adapter mechanism, a clearance of +/- 70 ° can be reduced at the key and a clearance of +/- 35 ° can be achieved on the threshing machine. led 8 and thus on the driven axis 7 lock input.

Ainsi, l'utilisation d'un mécanisme adaptateur de course 11 en sortie de verrou permet de conserver un débattement angulaire important au niveau de la clé en évitant d'entrer en collision avec des éléments présents dans l'environnement proche de la batteuse menée 8.Thus, the use of a stroke adapter mechanism 11 at the exit of the lock makes it possible to maintain a large angular deflection at the key by avoiding colliding with elements present in the environment close to the driven thresher 8 .

Par ailleurs, le couple transmis est augmenté dans les mêmes proportions.Moreover, the transmitted torque is increased in the same proportions.

Selon un deuxième exemple de réalisation illustré sur les figures 5 et 6, l'ensemble verrou-serrure de véhicule comporte un organe de liaison 4' comprenant une batteuse menant 10 à l'entrée de la serrure 3 et un mécanisme adaptateur de course 21 interposé entre l'axe mené 7 et la batteuse menant 10.According to a second exemplary embodiment illustrated on the figures 5 and 6 , the vehicle lock-lock assembly comprises a connecting member 4 'comprising a thresher leading to the input of the lock 3 and a race adapter mechanism 21 interposed between the driven shaft 7 and the driving thresher 10.

Dans ce deuxième exemple, le mécanisme adaptateur de course 21 est configuré pour être entraîné en pivotement par la batteuse menant 10 et pour entraîner l'axe mené 7 en augmentant le débattement angulaire de l'axe mené 7 par rapport au débattement angulaire de la batteuse menant 10.In this second example, the stroke adapter mechanism 21 is configured to be pivotally driven by the driving combine 10 and to drive the driven shaft 7 by increasing the angular displacement of the driven shaft 7 relative to the angular displacement of the threshing machine. leading 10.

L'organe de liaison 4' est réalisé comme l'organe de liaison 4 de l'exemple précédent. Il comprend une batteuse 8 et un mécanisme adaptateur de course 21 comportant une roue dentée 15 coaxiale et solidaire de l'axe menant 6, un pignon satellite 14 engrenant la roue dentée 15 et une couronne 12 coaxiale à l'axe menant 6 et solidaire de la batteuse menée 8, ladite couronne 12 présentant une denture périphérique interne 13 engrenant le pignon satellite 14.The connecting member 4 'is made as the connecting member 4 of the previous example. It comprises a threshing machine 8 and a travel adapter mechanism 21 comprising a gear wheel 15 coaxial and secured to the driving shaft 6, a pinion gear 14 meshing with the toothed wheel 15 and a ring 12 coaxial with the driving shaft 6 and integral with the driven thresher 8, said ring 12 having an internal peripheral gearing 13 meshing with the pinion satellite 14.

Toutefois, l'organe de liaison 4' est interposé entre un axe mené 7 et une batteuse menant 10 de sorte qu'en fonctionnement, il tourne dans l'autre sens : la batteuse menant 10 entraîne le mécanisme adaptateur de course qui entraîne l'axe mené 7. Le mécanisme adaptateur de course 21 augmente alors le débattement angulaire.However, the connecting member 4 'is interposed between a driven shaft 7 and a leading thresher 10 so that in operation, it rotates in the other direction: the driving thresher 10 drives the race adapter mechanism which drives the 7. The stroke adapter mechanism 21 then increases the angular deflection.

Plus précisément et comme dans l'exemple précédent, la batteuse menant 10 présente une forme sensiblement en disque avec une excroissance formant une extrémité 10a présentant par exemple un trou pour fixer une deuxième extrémité de l'élément de transmission 9, la première extrémité de l'élément de transmission 9 étant reliée à un élément du verrou (axe menant ou batteuse classique). En outre, la batteuse menant 10 est configuré pour pivoter autour de l'axe mené 7.More specifically and as in the previous example, the driving thresher 10 has a substantially disk-like shape with a protrusion forming an end 10a having for example a hole for fixing a second end of the transmission element 9, the first end of the transmission element 9 being connected to an element of the lock (driving axis or conventional thresher). In addition, the leading thresher 10 is configured to pivot about the driven axis 7.

La roue dentée 15 est solidaire de l'axe mené 7. Pour cela, la roue dentée 15 présente un orifice central 15a pour le passage de l'axe mené 7, l'axe mené 7 étant fixé dans l'orifice central 15a par tout moyen approprié, tel que par l'assemblage d'une clavette de l'élément de liaison 4'.The toothed wheel 15 is integral with the driven shaft 7. For this, the toothed wheel 15 has a central orifice 15a for the passage of the driven shaft 7, the driven shaft 7 being fixed in the central orifice 15a by any appropriate means, such as by assembling a key of the connecting element 4 '.

La roue dentée 15 est coaxiale à l'axe mené 7 et la couronne 12 est solidaire de la batteuse menant 10, c'est-à-dire que les axes de rotation A-A de la roue dentée 15, de l'axe mené 7 et de la batteuse menant 10 sont confondus.The toothed wheel 15 is coaxial with the driven shaft 7 and the ring gear 12 is integral with the driving combine 10, that is to say that the axes of rotation AA of the toothed wheel 15, the driven shaft 7 and of the leading thresher 10 are merged.

On prévoit que la batteuse menant 10 soit en liaison pivot avec l'axe mené 7 de sorte que le pivotement de la batteuse menant 10 soit guidé par l'axe mené 7.It is expected that the leading thresher 10 is in pivot connection with the driven axis 7 so that the pivoting of the driving thresher 10 is guided by the driven axis 7.

L'organe de liaison 4' comporte en outre un support de guide 17, fixé à la serrure 3, interposé entre l'axe mené 7 et la couronne 12. Le support de guide 17 en forme de disque, comporte un orifice central 17a pour le passage de l'axe mené 7 et un ergot 17b excentré saillant vers le pignon satellite 14. Le pignon satellite 14 est en liaison pivot avec l'ergot 17b de sorte que le pivotement du pignon satellite 14 soit guidé par l'ergot 17b.The connecting member 4 'further comprises a guide support 17, fixed to the lock 3, interposed between the driven shaft 7 and the ring 12. The guide support 17 in the form of a disc, comprises a central orifice 17a for the passage of the driven shaft 7 and an eccentric pin 17b protruding towards the pinion satellite 14. The pinion 14 is pivotally connected to the pin 17b so that the pivoting of the pinion 14 is guided by the pin 17b.

Le rayon de la denture R1 du pignon satellite 14, le rayon de la denture R2 de la roue dentée 15 et le rayon R3 de la couronne 12 satisfont la relation : R3 > R2 et R3 > R1 (figure 6).The radius of the toothing R1 of the planet pinion 14, the radius of the toothing R2 of the toothed wheel 15 and the radius R3 of the crown 12 satisfy the relation: R3> R2 and R3> R1 ( figure 6 ).

Le facteur de multiplication obtenu par le mécanisme adaptateur de course 21 est égal au diamètre de la couronne 12 divisé par le diamètre de la roue dentée 15.The multiplication factor obtained by the stroke adapter mechanism 21 is equal to the diameter of the ring 12 divided by the diameter of the toothed wheel 15.

Par exemple, pour multiplier par deux le débattement angulaire de l'axe mené 7 par rapport au débattement angulaire de la batteuse menant 10, le rayon de la denture périphérique interne R3 de la couronne 12 est sensiblement égal à 2*R1+R2, avec R1, le rayon de la denture du pignon satellite 14 et R2, le rayon de la denture de la roue denté 15.For example, to multiply by two the angular displacement of the driven axis 7 with respect to the angular displacement of the driving thresher 10, the radius of the internal peripheral gear R3 of the ring 12 is substantially equal to 2 * R1 + R2, with R1, the radius of the toothing of the planet pinion 14 and R2, the radius of the toothing of the toothed wheel 15.

En fonctionnement, comme on peut le voir sur la figure 6, en pivotant dans le sens antihoraire, la batteuse menant 10 solidaire de l'organe de transmission 9 fait pivoter la couronne 12 dans le sens antihoraire (flèche F1). Le pignon satellite 14 qui engrène la couronne 12 est alors entraîné dans le sens antihoraire (flèche F2) autour de l'ergot 17b. La roue dentée 15 qui engrène le pignon satellite 14 est entraîné dans le sens horaire entraînant l'axe mené 7 solidaire de la roue dentée 15 (flèche F3).In operation, as can be seen on the figure 6 , by pivoting counterclockwise, the leading thresher 10 secured to the transmission member 9 rotates the ring 12 in the counterclockwise direction (arrow F1). The planet gear 14 which meshes with the crown 12 is then driven counterclockwise (arrow F2) around the lug 17b. The toothed wheel 15 which meshes with the planet pinion 14 is driven in the clockwise direction driving the driven pin 7 integral with the toothed wheel 15 (arrow F3).

Le débattement angulaire de l'axe mené 7 est donc augmenté (par un coefficient deux dans cet exemple) par rapport à la course angulaire de la batteuse menant 10 et ceci dans un encombrement limité. L'utilisation d'un mécanisme adaptateur de course 21 permet de conserver le débattement angulaire de l'élément de la serrure 3 avec un débattement angulaire plus petit au niveau de la batteuse menant 10, évitant à cette dernière d'entrer en collision avec des éléments présent dans son environnement proche. Par ailleurs, le couple transmis est réduit dans les mêmes proportions entre la batteuse menant 10 et l'axe mené 7.The angular displacement of the driven shaft 7 is therefore increased (by a coefficient of two in this example) with respect to the angular stroke of the leading thresher 10 and this in a limited space. The use of a travel adapter mechanism 21 makes it possible to maintain the angular displacement of the element of the lock 3 with a smaller angular displacement at the level of the threshing machine 10, preventing the latter from colliding with elements present in its close environment. Furthermore, the transmitted torque is reduced in the same proportions between the leading thresher 10 and the driven axis 7.

Selon un troisième exemple de réalisation représenté en figure 7a, 7b, 7c, l'ensemble verrou-serrure comporte deux organes de liaison 4 et 4', un premier organe de liaison 4 en sortie du verrou 2 et un deuxième organe de liaison 4' en entrée de serrure 3. Les organes de liaison 4, 4' sont reliés par un élément de transmission 9, tel qu'une tringle 9a (figure 7a), un câble à traction et compression (dit « Push-Pull » en anglais ; figure 7b) ou un câble à compression en forme de boucle (dit « Pull-Pull » en anglais ; figure 7c).According to a third exemplary embodiment represented in figure 7a , 7b, 7c , the lock-lock assembly comprises two connecting members 4 and 4 ', a first connecting member 4 at the output of the latch 2 and a second connecting member 4' at the lock input 3. The connecting members 4, 4 ' are connected by a transmission element 9, such as a rod 9a ( figure 7a ), a cable with traction and compression (called "Push-Pull" in English; figure 7b ) or a compression cable in the form of a loop (called "Pull-Pull" in English; Figure 7c ).

Ainsi en sortie de verrou 2, un mécanisme adaptateur de course 11 est configuré pour être entraîné en pivotement par l'axe menant 6 solidaire du rotor de verrou et pour entraîner la batteuse menée 8 de manière à réduire d'un premier facteur M1, le débattement angulaire de la batteuse menée 8 par rapport au débattement angulaire de l'axe menant 6 et à augmenter d'un facteur équivalent M1, le couple exercé sur la batteuse menée 8 par rapport au couple exercé sur l'axe menant 6.Thus at the latch output 2, a travel adapter mechanism 11 is configured to be pivotally driven by the driving shaft 6 integral with the lock rotor and to drive the driven thresher 8 so as to reduce by a first factor M1 the angular displacement of the driven thresher 8 relative to the angular displacement of the driving shaft 6 and to increase by an equivalent factor M1, the torque exerted on the driven thresher 8 relative to the torque exerted on the driving shaft 6.

Puis en entrée de serrure 3, un mécanisme adaptateur de course 21 est configuré pour être entraîné en pivotement par la batteuse menant 10 de la serrure 3 et pour entraîner l'axe mené 7. Le débattement angulaire de l'axe mené 7 est augmenté par rapport au débattement angulaire de la batteuse menant 10 d'un deuxième facteur M2 et le couple exercé sur l'axe mené 7 est réduit d'un facteur équivalent M2 par rapport au couple exercé sur la batteuse menant 10.Then at the lock inlet 3, a stroke adapter mechanism 21 is configured to be pivotally driven by the driving drummer 10 of the lock 3 and to drive the driven axle 7. The angular displacement of the driven axle 7 is increased by relative to the angular displacement of the leading thresher 10 of a second factor M2 and the torque exerted on the driven shaft 7 is reduced by an equivalent factor M2 relative to the torque exerted on the threshing machine 10.

En entrée de serrure 3, le débattement angulaire de l'axe mené 7 est égal au débattement angulaire de l'axe menant 6 multiplié par le rapport M1 /M2 et le couple exercé sur l'axe mené 7 est égal au couple exercé sur l'axe menant 6 divisé par le produit M1*M2.At the entry of lock 3, the angular displacement of the driven axis 7 is equal to the angular displacement of the driving shaft 6 multiplied by the ratio M1 / M2 and the torque exerted on the driven axis 7 is equal to the torque exerted on the leading axis 6 divided by the product M1 * M2.

En choisissant judicieusement les rapports d'engrenage, il est alors possible de modifier les débattements angulaires et les couples exercés d'une part en entrée de serrure et d'autre part en sortie de verrou.By judiciously choosing the gear ratios, it is then possible to modify the angular deflections and the torques exerted on the one hand at the lock input and on the other hand at the latch output.

Par exemple, en choisissant des mécanismes adaptateurs de course de même coefficient, on réduit le débattement angulaire de la batteuse menée au niveau de la sortie du verrou et on raugmente le débattement angulaire au niveau de l'axe mené. Les débattements au niveau du verrou et de la serrure sont conservés tandis que des débattements angulaires intermédiaires plus petits permettent d'être transmis du verrou à la serrure sans risquer d'entrer en collision avec les éléments présents dans l'environnement intérieur de la porte.For example, by choosing race adapter mechanisms of the same coefficient, it reduces the angular movement of the thresher conducted at the output of the lock and increases the angular displacement at the driven axis. Lock and lock deflections are maintained while smaller intermediate angular deflections can be transmitted from the lock to the lock without the risk of colliding with the elements in the interior environment of the door.
