Description

L'invention concerne une poignée de véhicule automobile.The invention relates to a vehicle handle automobile.

L'invention concerne plus particulièrement une poignée de commande d'un ouvrant de véhicule automobile, du type dans lequel la poignée comporte une palette de commande qui est destinée à être déplacée par un utilisateur depuis une position de repos jusqu'à une position d'ouverture, le déplacement de la palette étant transmis à une serrure par l'intermédiaire d'une tringlerie comportant un renvoi articulé qui se déplace avec la palette depuis une position de repos jusqu'à une position d'ouverture, et du type dans lequel il est prévu un dispositif de détection du déplacement de la palette comportant un interrupteur qui est commandé par la palette par l'intermédiaire d'un mécanisme de transmission.The invention relates more particularly to a handle for controlling a motor vehicle opening, of the type in which the handle has a control palette which is intended to be moved by a user from a rest position to an open position, the movement of the pallet being transmitted to a lock by through a linkage with an articulated return which moves with the pallet from a rest position to an open position, and the type in which it is provided with a device for detecting the movement of the pallet having a switch which is controlled by the paddle through a transmission mechanism.

Il existe de nombreuses applications dans lesquelles on utilise un interrupteur pour détecter le fait qu'un utilisateur est en train de manipuler la palette en vue de tenter d'ouvrir l'ouvrant sur lequel est agencée la poignée.There are many applications in which uses a switch to detect the fact that a user is manipulating the pallet in an attempt to open the opening on which the handle is arranged.

Une de ces applications concerne le cas où le verrouillage et le déverrouillage d'un système de sécurité qui assure la condamnation de l'ouvrant sont subordonnés à une interrogation à distance, par une centrale antivol du véhicule, d'un badge de type radiofréquence porté par l'utilisateur. Dans un tel système, avant de déclencher le déverrouillage, la centrale antivol émet un signal d'interrogation et attend en retour un signal de réponse codé émis par le badge. La centrale antivol compare le signal de réponse reçu à un signal prédéterminé et, en cas de correspondance, déclenche à ce moment-là le déverrouillage de la serrure si bien que, en amenant la palette de la poignée vers sa position d'ouverture, l'utilisateur, dûment autorisé, peut alors ouvrir l'ouvrant. One of these applications relates to the case where the locking and unlocking a security system which ensures the condemnation of the opening are subject to a remote interrogation by an anti-theft control unit of the vehicle, a radio frequency badge worn by the user. In such a system, before triggering the unlocking, the anti-theft control unit emits an interrogation signal and waits for return a coded response signal sent by the badge. The anti-theft control unit compares the response signal received with a signal predetermined and, if matched, triggers at this then unlocking the lock so that in bringing the handle pallet to its open position, the user, duly authorized, can then open the door.

Un tel système de sécurité, qui permet de s'affranchir de l'utilisation d'une clé bu d'une télécommande, est souvent dénommé "système à accès main libre".Such a security system, which overcomes of using a key drunk from a remote control, is often called "hands-free access system".

Dans une telle application, la procédure d'échange de données entre la centrale antivol et le badge d'identification, l'étape de reconnaissance du signal de réponse, puis l'opération effective de déverrouillage de la serrure nécessitent un certain temps. Or, pour un grand confort d'utilisation d'un tel système de sécurité, il est important que l'utilisateur autorisé puisse ouvrir l'ouvrant dés qu'il a amené la palette de la poignée vers sa position d'ouverture. Aussi, dans ce but, il est nécessaire que la procédure d'identification puisse être déclenchée le plus tôt possible à partir du moment où, en déplaçant la palette, l'utilisateur manifeste sa volonté d'ouvrir l'ouvrant.In such an application, the procedure for exchanging data between the anti-theft control unit and the identification badge, the response signal recognition step, then the actual operation of unlocking the lock requires some time. However, for a great comfort of use of a such security system it is important that the user authorized can open the door as soon as he brought the pallet of the handle to its open position. Also, for this purpose, it it is necessary that the identification procedure can be triggered as soon as possible from the moment when, in moving the pallet, the user manifests his desire to open opening it.

L'invention a donc pour objet de proposer une nouvelle conception d'une poignée qui permette de provoquer un actionnement de l'interrupteur de déclenchement de la procédure d'identification le plus rapidement possible à partir du moment où la palette commence à être déplacée, ce dispositif ne devant en aucun cas limiter la course de la palette vers sa position d'ouverture, afin que celle-ci puisse commander une serrure de type mécanique, et le dispositif devant par ailleurs être fiable et simple à fabriquer.The object of the invention is therefore to propose a new design of a handle that allows to provoke a actuation of the tripping switch of the identification procedure as quickly as possible from the moment the pallet starts to move, this device must in no case limit the stroke of the pallet towards its open position, so that it can order a mechanical type lock, and the device which should also be reliable and simple to manufacture.

Dans ce but, l'invention propose une poignée de commande d'un ouvrant de véhicule automobile, du type dans lequel la poignée comporte une palette de commande qui est destinée à être déplacée par un utilisateur depuis une position de repos jusqu'à une position d'ouverture, le déplacement de la palette étant transmis à une serrure par l'intermédiaire d'une tringlerie comportant un renvoi articulé qui se déplace avec la palette depuis une position de repos jusqu'à une position d'ouverture, et du type dans lequel il est prévu un dispositif de détection du déplacement de la palette comportant un interrupteur qui est commandé par la palette par l'intermédiaire d'un mécanisme de transmission, caractérisé en ce que le mécanisme de transmission comporte un levier qui est mobile entre deux positions inactive et active qui correspondent à deux états différents de ['interrupteur, en ce que le levier est sollicité par des premiers moyens élastiques en direction de sa position active, en ce que le renvoi articulé, lorsqu'il est en position de repos, forme une butée qui maintien le levier en position inactive, et en ce que, lorsque le renvoi est amené avec la palette vers sa position d'ouverture, le levier se déplace vers sa position active sous l'action des moyens élastiques qui le maintiennent en appui contre le renvoi jusqu'à une position intermédiaire de ce dernier pour laquelle le levier atteint sa position active.To this end, the invention provides a handful of control of a motor vehicle opening, of the type in which the handle has a control palette which is intended to be moved by a user from a position rest to an open position, the movement of the pallet being transmitted to a lock via a linkage comprising an articulated return which moves with the pallet from a rest position to a position opening, and of the type in which a device is provided detection of the movement of the pallet comprising a switch which is controlled by the pallet via a transmission mechanism, characterized in that the transmission mechanism has a lever which is movable between two inactive and active positions which correspond to two different states of the switch, in that the lever is stressed by first elastic means towards its active position, in that the articulated return, when in rest position, forms a stop which keeps the lever in inactive position, and in that, when the diversion is brought with the pallet in its open position, the lever moves to its active position under the action of the means elastic bands that keep it pressed against the return up to an intermediate position of the latter for which the lever reaches its active position.

Pour faciliter la compréhension du texte, on définira par convention les notions d"'horizontale" et de "verticale" telles qu'elles apparaissent sur les figures 1 et 2, la direction longitudinale de la palette de commande 14 correspondant donc à la direction horizontale et la direction verticale étant représentée par l'axe A1 de pivotement de la palette de commande 14 par rapport au support 12, cet axe A1 étant généralement parallèle au panneau de carrosserie de l'ouvrant.To facilitate the understanding of the text, we will define by convention the notions of "horizontal" and "vertical" as that they appear in Figures 1 and 2, the direction longitudinal of the corresponding control paddle 14 so with the horizontal direction and the vertical direction being represented by the pivot axis A1 of the pallet control 14 relative to the support 12, this axis A1 being generally parallel to the body panel of opening it.

Ainsi, comme on peut le voir notamment sur la figure 2, lorsque la palette de commande 14 est amenée vers sa position d'ouverture, son extrémité longitudinale arrière 18 se décale transversalement vers l'extérieur par rapport au support 12 qui reste fixe. L'extrémité arrière 18 de la palette de commande 14 entraíne, par l'intermédiaire d'un pion 20, un renvoi articulé 22 qui fait partie d'une tringlerie par laquelle la palette de commande 14 peut agir sur une serrure qui assure le maintien de l'ouvrant en position fermée. Le renvoi articulé 22 est articulé sur le support 12 autour d'un axe A2 longitudinal. Ainsi, lorsque la palette de commande 14 est amenée de sa position de repos à sa position d'ouverture, le renvoi articulé 22 pivote lui aussi, autour de l'axe A2, d'une position de repos illustrée à la figure 1 jusqu'à une position d'ouverture illustrée à la figure 2. Le reste de la tringlerie qui permet la commande de la serrure de l'ouvrant n'est pas illustré sur les figures.Thus, as can be seen in particular in FIG. 2, when the control paddle 14 is brought to its open position, its rear longitudinal end 18 is shifts transversely outward relative to the support 12 which remains fixed. The rear end 18 of the pallet command 14 drives, via a pin 20, a articulated return 22 which is part of a linkage by which the control paddle 14 can act on a lock which ensures maintaining the opening in the closed position. The articulated reference 22 is articulated on the support 12 around an axis A2 longitudinal. So when the control paddle 14 is brought from its rest position to its open position, the articulated return 22 also pivots, around the axis A2, by a rest position illustrated in Figure 1 to a position shown in Figure 2. The rest of the linkage that allows control of the door lock is not illustrated in the figures.

Ainsi que cela sera décrit plus en détail ci-après, le renvoi articulé 22 est rappelé élastiquement par un ressort hélicoïdal à action angulaire 24 vers sa position de repos. Avantageusement, ce ressort 24 est dimensionné de manière à ce que, en revenant vers sa position de repos, le renvoi articulé 22 ramène automatiquement la palette de commande 14 vers sa position de repos, par l'intermédiaire du pion 20, dès que l'utilisateur relâche la palette de commande 14.As will be described in more detail below, the articulated return 22 is resiliently recalled by a spring helical with angular action 24 towards its rest position. Advantageously, this spring 24 is dimensioned so as to what, returning to its rest position, the return articulated 22 automatically brings back the control paddle 14 towards its rest position, via the pin 20, as soon as the user releases the control paddle 14.

Selon l'invention, la poignée 10 comporte par ailleurs un interrupteur 50 (illustré aux figures 4 à 6) qui est par exemple agencé à l'intérieur d'un boítier 26 faisant partie du support 12 de la poignée et qui est destiné à être actionné entre un état ouvert et un état fermé par un levier 28.According to the invention, the handle 10 also comprises a switch 50 (illustrated in FIGS. 4 to 6) which is for example arranged inside a housing 26 forming part of the support 12 of the handle and which is intended to be actuated between a state open and closed by a lever 28.

Dans l'exemple de réalisation illustré sur les figures, le levier 28 est un levier qui est monté pivotant sur le support 12 autour de l'axe A2 de rotation du renvoi articulé 22, dans le prolongement longitudinal et en avant de celui-ci.In the embodiment illustrated in the figures, the lever 28 is a lever which is pivotally mounted on the support 12 around the axis A2 of rotation of the articulated return 22, in the longitudinal extension and in front of it.

Le levier 28 est ainsi susceptible de pivoter d'une position inactive, illustrée à la figure 1, à une position active, illustrée à la figure 2, et il est sollicité vers cette dernière position par un ressort hélicoïdal à action angulaire 30.The lever 28 is thus capable of pivoting by a inactive position, illustrated in FIG. 1, in an active position, illustrated in figure 2, and it is biased towards the latter position by a helical spring with angular action 30.

Comme on peut le voir plus particulièrement sur la figure 3, le renvoi articulé 22 comporte pour l'essentiel une tige 32 qui s'étend longitudinalement selon l'axe d'articulation du renvoi. La tige 32 comporte, à une extrémité longitudinale arrière, un bras de commande 34 qui s'étend perpendiculairement à l'axe A2 et qui comporte notamment des moyens 36 d'accrochage de la tringlerie et des moyens 38 pour coopérer avec le pion 20 de la palette de commande 14. A son extrémité avant, la tige 32 est munie d'un bras d'actionnement 40 comportant notamment un ergot de retenue 42 qui s'étend axialement vers l'avant et qui est destiné à coopérer avec le levier 28 d'actionnement de l'interrupteur 50.As we can see more particularly on the Figure 3, the articulated reference 22 essentially comprises a rod 32 which extends longitudinally along the axis of articulation of the reference. The rod 32 has, at a longitudinal end rear, a control arm 34 which extends perpendicularly to axis A2 and which in particular comprises means 36 for attaching the linkage and means 38 for cooperating with the pin 20 of the control paddle 14. At its end front, the rod 32 is provided with an actuating arm 40 comprising in particular a retaining lug 42 which extends axially forward and which is intended to cooperate with the lever 28 for actuating the switch 50.

En effet, le levier 28 comporte pour l'essentiel un tambour tubulaire 44 d'axe A2 qui est pourvu à son extrémité arrière d'un doigt de commande 46, destiné à coopérer avec l'ergot axial 42 du bras d'actionnement 40 du renvoi 22, et d'un doigt d'actionnement 48 destiné à coopérer avec l'interrupteur 50. Le doigt de commande 46 et le doigt d'actionnement 48 sont agencés dans le même plan transversal mais ils s'étendent diamétralement à l'opposé l'un de l'autre par rapport à l'axe A2.Indeed, the lever 28 essentially comprises a tubular drum 44 of axis A2 which is provided at its end rear of a control finger 46, intended to cooperate with the axial lug 42 of the actuating arm 40 of the reference 22, and of a actuating finger 48 intended to cooperate with the switch 50. The control finger 46 and the actuation finger 48 are arranged in the same transverse plane but they extend diametrically opposite each other by relative to axis A2.

Le fonctionnement du dispositif d'actionnement de l'interrupteur est plus particulièrement illustré sur les figures 4 à 6 qui sont des vues schématiques selon l'axe A2, en regardant d'avant vers l'arrière.The operation of the actuation device the switch is more particularly illustrated in FIGS. 4 to 6 which are schematic views along the axis A2, in looking from front to back.

A la figure 4, le dispositif est illustré lorsque la poignée est au repos, c'est-à-dire lorsque personne n'agit sur celle-ci. Le renvoi articulé 22 occupe alors sa position de repos, de même que la palette de commande 14 dont on peut voir l'extrémité arrière 18. Dans ce cas, on voit que le levier 28 est dans sa position inactive dans laquelle il n'exerce aucune action sur l'interrupteur 50 qui est par exemple alors dans un état ouvert. Toutefois, le levier 28 est sollicité par le ressort 30 de manière à avoir tendance à pivoter autour de l'axe A2 vers sa position active, c'est-à-dire dans le sens anti-horaire en considérant la figure 4. Cependant, selon l'invention, le doigt de commande 46 du levier 28 est alors en appui contre l'ergot de retenue 42 du renvoi 22 de sorte que le levier 28 est ainsi maintenu par le renvoi 22 dans sa position inactive, en dépit de l'action du ressort 30.In Figure 4, the device is illustrated when the handle is at rest, that is to say when no one acts on it. The articulated return 22 then occupies its rest position, same as the control palette 14 which can be seen the rear end 18. In this case, it can be seen that the lever 28 is in its inactive position in which it exerts no action on switch 50 which is for example then in a open state. However, the lever 28 is biased by the spring 30 so as to have a tendency to pivot around the axis A2 towards its active position, that is to say counterclockwise in considering FIG. 4. However, according to the invention, the finger 46 of the lever 28 is then pressed against the lug retaining 42 of the reference 22 so that the lever 28 is thus maintained by reference 22 in its inactive position, despite spring action 30.

A la figure 5, on a illustré le dispositif d'actionnement dans une position intermédiaire, lorsqu'un utilisateur est en train d'amener la palette de commande 14 de la poignée vers sa position d'ouverture. Dans cette position intermédiaire, on peut voir que l'extrémité arrière 18 de la palette de commande 14 est déplacée transversalement vers l'extérieur, c'est-à-dire vers la droite en considérant la figure 5, d'une certaine distance, faible. La palette 14 emmène avec elle, par l'intermédiaire du pion de commande 20, le renvoi 22 qui pivote autour de l'axe A2, dans le sens anti-horaire en considérant la figure 5, jusqu'à une position intermédiaire. Lors du déplacement du renvoi 22, l'ergot de retenue 42 de celui-ci pivote autour de l'axe A2 de sorte que le levier 28 peut, sous l'effet du ressort 30, se déplacer lui aussi du même angle, son doigt de commande 46 restant au contact de l'ergot de retenue 42. En pivotant autour de l'axe A2, le levier 28 peut donc solliciter l'interrupteur 50 vers un autre état, c'est-à-dire par exemple un état fermé.In Figure 5, the actuating device is illustrated in an intermediate position, when a user is in bringing the control paddle 14 from the handle to its open position. In this intermediate position, we can see that the rear end 18 of the control paddle 14 is moved transversely outward, that is to say to the right considering figure 5, of a certain distance, small. Pallet 14 takes with it, by via the control pin 20, the reference 22 which rotates around axis A2, counterclockwise while considering Figure 5, to an intermediate position. When displacement of the reference 22, the retaining lug 42 thereof pivots around the axis A2 so that the lever 28 can, under the effect of spring 30, also move the same angle, its control finger 46 remaining in contact with the retaining lug 42. By pivoting around the axis A2, the lever 28 can therefore press switch 50 to another state, i.e. by example a closed state.

On voit que, du fait de la géométrie des pièces et des démultiplications de mouvements ainsi obtenus, un mouvement très faible de la palette de commande 14 permet de commander l'interrupteur 50 entre ses deux états. Ainsi, dés que l'utilisateur commence de manipuler la palette de commande 14, l'interrupteur 50 est en mesure de commander le déclenchement par exemple d'une procédure d'identification d'un badge porté par l'utilisateur. We see that, due to the geometry of the parts and reduction of movements thus obtained, a movement very low control pallet 14 allows control the switch 50 between its two states. So, dice that the user begins to manipulate the palette of command 14, switch 50 is able to command the initiation, for example, of an identification procedure a badge worn by the user.

Selon l'invention, on voit à la figure 6 que, une fois l'interrupteur 50 déclenché, l'utilisateur peut poursuivre le mouvement d'ouverture de la palette de commande 14 qui entraíne avec elle la poursuite du pivotement du renvoi articulé 22 autour de l'axe A2. Au contraire, on voit que le levier 28 reste alors dans sa position active qu'il a atteint dès la figure 5, l'ergot de retenue 42 et le doigt de commande 46 du levier 28 n'étant plus alors en contact l'un avec l'autre. De la sorte, le dispositif permet de commander un interrupteur 50 possédant une très faible course d'actionnement, sans limiter en aucune façon la course, angulaire du renvoi 22 et donc de la palette de commande 14 entre leur position de repos et leur position d'ouverture.According to the invention, it can be seen in FIG. 6 that, once the switch 50 tripped, the user can continue the opening movement of the control paddle 14 which with it continues the pivoting of the articulated gear 22 around the axis A2. On the contrary, we see that the lever 28 then remains in its active position which it has reached from the figure 5, the retaining lug 42 and the control finger 46 of the lever 28 no longer being in contact with each other. In this way, the device makes it possible to control a switch 50 having a very short actuation stroke, without limiting in no way the stroke, angular of the reference 22 and therefore of the control paddle 14 between their rest position and their open position.

En sens inverse, lorsque l'utilisateur lâche la palette de commande 14, le renvoi articulé 22 est ramené vers sa position de repos par le ressort 24 et le renvoi 22 ramène de cette manière la palette de commande 14 par l'intermédiaire du pion de commande 20. Lorsque le renvoi 22 arrive à sa position intermédiaire, son ergot de retenue 42 arrive en contact avec le doigt de commande 46 du levier 28 et, lorsque le renvoi 22 poursuit son retour vers sa position de repos, l'ergot de retenue 42 provoque le pivotement du levier 28 de nouveau vers sa position inactive, à l'encontre de l'action du ressort 30, ce qui provoque un nouveau changement d'état de l'interrupteur 50.Conversely, when the user releases the pallet of control 14, the articulated reference 22 is brought back to its rest position by the spring 24 and the return 22 brings back this way the control paddle 14 via the control pin 20. When the reference 22 arrives at its intermediate position, its retaining lug 42 comes in contact with the control finger 46 of the lever 28 and, when the reference 22 continues its return to its rest position, the retaining lug 42 causes the lever 28 to pivot back to its inactive position, contrary to the action of the spring 30, which causes a new change of state of switch 50.

Dans le cas où l'intégralité de l'effort de rappel du renvoi 22 est assurée par le ressort 24, il est nécessaire de veiller à ce que ce dernier exerce sur le renvoi 22 un couple de rappel supérieur au couple exercé sur le renvoi 22 par le levier 28 qui est sollicité en sens inverse par le ressort 30.In the event that the entire recall effort return 22 is provided by the spring 24, it is necessary to ensure that the latter exerts a torque on the reference 22 of recall greater than the torque exerted on the reference 22 by the lever 28 which is biased in the opposite direction by the spring 30.

Selon un autre aspect de l'invention, la poignée 10 comporte des moyens qui permettent de simplifier son assemblage, et qui permettent notamment d'éviter que l'action du ressort de rappel 24 du renvoi 22 ne gêne les opérations d'assemblage.According to another aspect of the invention, the handle 10 includes means which make it possible to simplify its assembly, and which in particular prevent the action return spring 24 of reference 22 does not interfere with operations assembly.

A cet effet, et comme on peut le voir notamment sur la figure 7, le renvoi articulé 22 comporte deux parties avant 52 et arrière 54.To this end, and as can be seen in particular on the Figure 7, the articulated reference 22 has two front parts 52 and rear 54.

La partie avant 52 comporte un fourreau tubulaire 56 cylindrique de révolution d'axe A2 à l'extrémité avant duquel est agencé le bras d'actionnement 40 qui porte l'ergot de retenue 42. La partie arrière 54 comporte un arbre cylindrique 58 d'axe A2 qui est destiné à être reçu à l'intérieur du fourreau tubulaire 56 de la partie avant, et qui porte à son extrémité arrière le bras de commande 34 du renvoi 22.The front part 52 comprises a tubular sheath 56 cylindrical of revolution of axis A2 at the front end of which is arranged the actuating arm 40 which carries the lug of retainer 42. The rear part 54 comprises a cylindrical shaft 58 of axis A2 which is intended to be received inside the sheath tubular 56 of the front part, and which carries at its end rear the control arm 34 of the reference 22.

Lorsque les deux parties 52, 54 sont assemblées, l'arbre 58 est reçu dans le fourreau 56 qui forme alors la tige 32 de liaison des deux bras 34, 40 du renvoi 22. Comme cela est plus particulièrement visible sur la figure 12, les deux parties 52, 54 sont pourvues d'un système 68 à tenon et à mortaise qui est agencé à l'extrémité avant de l'arbre 58 et du fourreau 56, et qui permet, lorsque les deux parties sont assemblées axialement l'une dans l'autre, d'assurer l'accouplement en rotation autour de l'axe A2 des deux parties 52, 54.When the two parts 52, 54 are assembled, the shaft 58 is received in the sheath 56 which then forms the rod 32 connecting the two arms 34, 40 of the reference 22. Like this is more particularly visible in FIG. 12, the two parts 52, 54 are provided with a tenon system 68 and mortise which is arranged at the front end of the shaft 58 and the sleeve 56, and which allows, when the two parts are axially assembled one inside the other, ensuring the coupling in rotation around the axis A2 of the two parts 52, 54.

Toutefois, tant que l'arbre 58 n'est pas engagé axialement complètement au fond du fourreau 56, les deux parties 52, 54 sont libres de pivoter en rotation l'une par rapport à l'autre autour de l'axe A2.However, as long as the shaft 58 is not axially engaged completely at the bottom of the sleeve 56, the two parts 52, 54 are free to rotate in rotation with respect to the other around the axis A2.

Le ressort 24 de rappel du renvoi 22 est constitué par un ressort hélicoïdal à action angulaire qui est enroulé autour du fourreau 56, et donc autour de la tige 32, et qui comporte un brin avant 60 et un brin arrière 62 qui s'étendent chacun radialement vers l'extérieur à l'extrémité axiale correspondante de l'enroulement hélicoïdal. Le brin arrière 62 est destiné à venir en appui contre une surface d'appui 64 solidaire du bras de commande 34 du renvoi 22, c'est-à-dire solidaire de la partie arrière 54 de celui-ci. Au contraire, le brin avant 60 est destiné, lorsque la poignée est entièrement assemblée et en état de fonctionner, à venir en appui contre le support 12 de la poignée 10. Ainsi, lorsque le renvoi 22 pivote autour de l'axe A2, les deux brins 60, 62 sont déplacés angulairement l'un par rapport à l'autre, ce qui contraint le ressort 24.The return spring 24 of the reference 22 is constituted by a coil spring with angular action which is wound around sheath 56, and therefore around the rod 32, and which comprises a front strand 60 and a rear strand 62 which each extend radially outward at the corresponding axial end of the helical winding. The rear strand 62 is intended for come to bear against a bearing surface 64 secured to the arm 34 of the reference 22, that is to say integral with the rear portion 54 thereof. On the contrary, the strand before 60 is intended, when the handle is fully assembled and in working condition, coming to bear against the support 12 of the handle 10. Thus, when the reference 22 pivots about the axis A2, the two strands 60, 62 are angularly displaced one by relation to the other, which constrains the spring 24.

Toutefois, pour augmenter la force de rappel du ressort 24, sans en augmenter inconsidérément les dimensions, il est préférable que celui-ci soit précontraint au moment du montage, c'est-à-dire que même lorsque l'ensemble de la poignée est en position de repos, il exerce sur le renvoi 22 une force déjà importante. Pour réaliser cette précontrainte du ressort 24, sans rendre le montage du renvoi 22 trop complexe, on a prévu que, lors de l'assemblage de la poignée 10, le brin avant 60 du ressort 24 soit plaqué en appui contre une surface 66 solidaire du bras d'actionnement 40 de la partie avant 52 du renvoi 22.However, to increase the return force of the spring 24, without unduly increasing its dimensions, it is preferable that this is prestressed at the time of mounting, that is to say that even when the whole of the handle is in the rest position, it exerts on the reference 22 a already significant force. To achieve this prestressing of the spring 24, without making the assembly of the return 22 too complex, we planned that when assembling the handle 10, the front strand 60 of the spring 24 is pressed against a surface 66 secured to the actuating arm 40 of the part before 52 of reference 22.

Avantageusement, ainsi que cela est représenté à la figure 8, les deux brins 60, 62 peuvent être amenés en appui contre leurs surfaces d'appui respectives 66, 64 sans que les deux parties 52, 54 soient complètement emboítées axialement l'une dans l'autre, c'est-à-dire sans qu'elles ne soient encore liées en rotation par les moyens d'accouplement. De la sorte, ainsi qu'on l'a représenté à la figure 8, il est possible de précontraindre le ressort 24 en faisant tourner les deux parties 52, 54 l'une par rapport à l'autre autour de l'axe A2. Lorsque l'on a atteint le degré de précontrainte voulu, on termine l'assemblage du renvoi 22 en rapprochant axialement les deux parties 52, 54 de celui-ci, jusqu'à les emboíter complètement l'une dans l'autre, ainsi que cela est représenté sur la figure 9.Advantageously, as shown in the Figure 8, the two strands 60, 62 can be brought into abutment against their respective bearing surfaces 66, 64 without the two parts 52, 54 are completely nested axially one inside the other, that is to say without them being yet linked in rotation by the coupling means. In this way, as shown in Figure 8, it is possible to preload spring 24 by rotating the two parts 52, 54 relative to each other around the axis A2. When we have reached the desired degree of prestressing, we finish assembling the return 22 by bringing the two axially closer together parts 52, 54 of it, until they fit completely one inside the other, as shown in FIG. 9.

Toutefois, comme on peut le voir sur les figures 8 à 11, les deux parties 52, 54 du renvoi 22 comportent des moyens complémentaires qui permettent d'éviter que, avant qu'elles ne soient complètement rendues solidaires en rotation par le système 68 à tenon et mortaise, le ressort 24 ne puisse se relâcher. A cet effet, l'arbre 58 de la partie arrière du renvoi 22 comporte un ergot radial externe 70 destiné à être engagé dans une fente longitudinale 72 qui est aménagée dans le fourreau 56 et qui débouche longitudinalement dans l'extrémité arrière de celui-ci.However, as can be seen in Figures 8-11, the two parts 52, 54 of the reference 22 include means which prevent, before they are completely secured in rotation by the system 68 with tenon and mortise, the spring 24 cannot be to release. To this end, the shaft 58 of the rear part of the reference 22 has an external radial lug 70 intended to be engaged in a longitudinal slot 72 which is arranged in the sleeve 56 and which opens longitudinally into the end back of it.

Comme on peut le voir plus particulièrement sur la figure 10, la fente 72 possède au moins un bord longitudinal 74 qui comporte un décrochement 76, en l'occurrence formé par un pan incliné tourné vers l'avant. Le décrochement 76 est formé dans le bord 74 contre lequel l'ergot 70 vient en appui sous l'action du ressort de rappel 24. De la sorte, une fois que l'ergot 70 est engagé dans la fente axialement au-delà du décrochement 76, ce dernier empêche tout retrait vers l'arrière de l'arbre 58 par rapport au fourreau 56, ce qui empêche les deux parties 52, 54 de se désolidariser.As we can see more particularly on the Figure 10, the slot 72 has at least one longitudinal edge 74 which includes a recess 76, in this case formed by an inclined side facing forward. The step 76 is formed in the edge 74 against which the lug 70 comes to bear under the action of the return spring 24. In this way, once the lug 70 is engaged in the slot axially beyond the recess 76, the latter prevents any withdrawal to the rear of the shaft 58 relative to the sheath 56, which prevents two parts 52, 54 to separate.

Toutefois, l'ergot 70 et la fente 72 ne sont pas prévus pour encaisser la totalité du couple transmis par le renvoi 22, ce couple étant de préférence transmis par le système 68 à tenon et à mortaise décrit précédemment.However, the lug 70 and the slot 72 are not provided to collect the entire torque transmitted by the reference 22, this torque is preferably transmitted by the system 68 to tenon and mortise described above.

Comme on le voit, cette conception du renvoi 22 permet donc d'une part d'effectuer de manière particulièrement simple la précontrainte du ressort 24 et il permet ensuite le montage du renvoi 22 sur le support 12 sans que ce ressort 24 puisse perturber les opérations de montage. As can be seen, this design of the reference 22 allows on the one hand to perform in a particularly simple way the preload of spring 24 and then allows mounting of the reference 22 on the support 12 without this spring 24 can disrupt assembly operations.

Une fois le renvoi 22 monté sur la poignée, il est alors passible de dégager le brin avant 60 du ressort 24 de sa surface d'appui 66, celui-ci venant alors naturellement en appui contre le support de la poignée 10 ainsi que cela est plus particulièrement représenté sur la figure 13.Once the reference 22 is mounted on the handle, it is then liable to release the front strand 60 of the spring 24 from its bearing surface 66, the latter then coming naturally in support against the support of the handle 10 as is more particularly shown in FIG. 13.

Comme on peut le voir sur les figures 1 et 2, la poignée selon l'invention est donc particulièrement intéressante en ce que le dispositif d'actionnement de l'interrupteur est très peu encombrant, notamment selon la direction transversale qui correspond par exemple à l'épaisseur de l'ouvrant, en ce qu'il nécessite un nombre réduit de pièces, et en ce qu'il est d'un montage particulièrement aisé.As can be seen in Figures 1 and 2, the handle according to the invention is therefore particularly advantageous in that that the switch actuator is very little bulky, especially in the transverse direction which corresponds for example to the thickness of the opening, in that it requires a reduced number of parts, and in that it is of a particularly easy mounting.
