Description

La présente invention concerne une poignée de porte affleurante et son dispositif de déverrouillage d'une serrure de porte, notamment bien que non exclusivement une serrure de porte de véhicule automobile.The present invention relates to a flush door handle and its device for unlocking a door lock, in particular although not exclusively a motor vehicle door lock.

On connaît une poignée de porte non affleurante montée pour pivoter telle que décrite dans les documents DE 298 04 105 U1 ou encore US 2014/230329 A1 . Une telle poignée pivotante permet de protéger la serrure de porte et ainsi évite l'encrassement de la serrure. Une serrure de véhicule est par exemple décrite par le document EP 1 262 626 A2 .A non-flush door handle mounted to pivot is known as described in the documents DE 298 04 105 U1 or US 2014/230329 A1 . Such a pivoting handle makes it possible to protect the door lock and thus prevents fouling of the lock. A vehicle lock is for example described by the document EP 1 262 626 A2 .

Ce type de poignée de porte pivotante qui peut être affleurante telle que celle décrite dans le document WO 2014/049026 A1 permet déjà un accès facilité à la serrure de porte en cas de panne. La facilité d'accès est permise puisqu'une extrémité de la poignée est laissée libre.This type of pivoting door handle which can be flush such as that described in the document WO 2014/049026 A1 already allows easy access to the door lock in the event of a breakdown. Ease of access is permitted since one end of the handle is left free.

On s'intéresse plus particulièrement au véhicule automobile est équipé d'une serrure de porte associée à une poignée de porte affleurante montée pour coulisser dans une ouverture de la porte entre une position de repos dans laquelle la poignée affleure la porte et une position de travail dans laquelle la poignée est en saillie par rapport à la porte, il est généralement prévu une motorisation assurant le passage de la position de repos à la position de travail après identification de la personne tentant d'ouvrir la porte.We are more particularly interested in the motor vehicle is equipped with a door lock associated with a flush door handle mounted to slide in an opening of the door between a rest position in which the handle is flush with the door and a working position in which the handle projects relative to the door, a motorization is generally provided ensuring passage from the rest position to the working position after identification of the person attempting to open the door.

Lorsque la motorisation est en panne, quelle qu'en soit la raison, il faut pouvoir ouvrir la porte manuellement. A cet effet, il est généralement prévu un mécanisme à clé qui débouche sur la paroi de la porte. Toutefois, ce mécanisme n'étant que rarement voire même jamais utilisé, il existe un risque d'encrassement empêchant l'ouverture manuelle de la porte. De façon connue, le mécanisme à clé est agencé à côté de la poignée affleurante coulissante. Pour prévenir ce risque, l'extrémité du cylindre est recouverte d'un volet coulissant ou d'un petit capot, mais ceci ne fait que déplacer le problème, le volet coulissant ou le petit capot étant soumis aux intempéries. Dans le cas du document WO 2016/188694 A1 , la poignée coullissante décrite intègre le mécanisme à clé en son sein, il n'y a donc pas lieu de chercher à le protéger.When the motorisation is faulty, whatever the reason, it is necessary to be able to open the door manually. For this purpose, a key mechanism is generally provided which opens onto the wall of the door. However, since this mechanism is only rarely or even never used, there is a risk of fouling preventing manual opening of the door. In known manner, the key mechanism is arranged next to the flush sliding handle. To prevent this risk, the end of the cylinder is covered with a sliding shutter or a small hood, but this only shifts the problem, the sliding shutter or the small hood being exposed to the weather. In the case of the document WO 2016/188694 A1 , the sliding handle described incorporates the key mechanism within it, so there is no need to seek to protect it.

Un but de l'invention est de proposer un mécanisme de déverrouillage d'une serrure de porte dont le fonctionnement soit garanti dans des conditions habituelles d'utilisation.An object of the invention is to provide a mechanism for unlocking a door lock whose operation is guaranteed under normal conditions of use.

En vue de la réalisation de ce but, on prévoit une poignée de porte selon la revendication 1.In order to achieve this object, a door handle according to claim 1 is provided.

Ainsi, lors d'une utilisation courante du véhicule, l'entrée du mécanisme de déverrouillage est protégée par la poignée, de sorte que le risque d'encrassement est considérablement minimisé.Thus, during normal use of the vehicle, the entrance to the unlocking mechanism is protected by the handle, so that the risk of fouling is considerably minimized.

Selon une version avantageuse de l'invention, l'inclinaison est suffisante pour permettre l'introduction du cylindre dans le boitier par l'extérieur de la porte lorsque la poignée est dans la position de travail.According to an advantageous version of the invention, the inclination is sufficient to allow the introduction of the cylinder into the box from the outside of the door when the handle is in the working position.

Selon une autre version avantageuse de l'invention, le mécanisme de déverrouillage comporte un organe d'accouplement entre le cylindre et l'organe de manœuvre de l'élément de déverrouillage de la serrure, l'organe d'accouplement ayant un axe d'entrée et un axe de sortie qui s'étendent selon deux directions différentes. Ainsi il est possible d'adapter la position du cylindre à la configuration générale de la serrure de porte.According to another advantageous version of the invention, the unlocking mechanism comprises a coupling member between the cylinder and the maneuvering member of the unlocking element of the lock, the coupling member having an axis of entry and an exit axis which extend in two different directions. Thus it is possible to adapt the position of the cylinder to the general configuration of the door lock.

Selon d'autres caractéristiques de l'invention pouvant être mises en œuvre seules ou en combinaison : l'organe d'accouplement comprend des engrenages coniques; l'organe d'accouplement comprend un montage de cardan; l'organe d'accouplement comprend un engrenage conique fixé au cylindre, et un engrenage conique fixé à une platine portant une partie du montage de cardan ; le cylindre est monté de façon amovible par l'extérieur de la porte . Ainsi il est possible d'effectuer des opérations de finition, notamment une mise en peinture de la porte, sans risquer d'affecter le fonctionnement du mécanisme de déverrouillage.According to other characteristics of the invention which can be implemented alone or in combination: the coupling member comprises bevel gears; the coupling member comprises a universal joint assembly; the coupling member comprises a bevel gear fixed to the cylinder, and a bevel gear fixed to a plate carrying part of the gimbal assembly; the cylinder is removably mounted from the outside of the door. Thus it is possible to carry out finishing operations, in particular painting the door, without risking affecting the operation of the unlocking mechanism.

Selon encore une autre caractéristique de l'invention,le mécanisme comporte un organe de déverrouillage du cylindre accessible par la feuillure de la porte.According to yet another characteristic of the invention, the mechanism comprises a cylinder unlocking member accessible through the rebate of the door.

En référence aux figures, l'invention concerne un mécanisme de commande de la poignée 1 d'une porte 2. La poignée 1 est mobile entre une position de repos dans laquelle la poignée affleure la porte, et une position de travail dans laquelle la poignée est en saillie par rapport à la porte comme illustré sur la figure 1. Le mécanisme de commande comprend un boîtier 3 équipé de bossages 4 de fixation du boitier à la porte. La poignée 1 est montée pour coulisser dans une ouverture 5 de la porte.With reference to the figures, the invention relates to a mechanism for controlling the handle 1 of a door 2. The handle 1 is movable between a rest position in which the handle is flush with the door, and a working position in which the handle protrudes from the door as shown in the figure 1 . The control mechanism comprises a box 3 equipped with bosses 4 for fixing the box to the door. The handle 1 is mounted to slide in an opening 5 of the door.

Dans le mode de réalisation illustré, la poignée 1 est creuse. Le mécanisme de manœuvre de la poignée comporte un premier levier 6 ayant une forme générale de Y comprenant une queue 7 cambrée vers l'intérieur de la poignée et montée de façon articulée sur un axe 8 porté par la poignée, et deux branches 9 symétriques par rapport à un plan médian s'étendant selon une direction longitudinale de la poignée, et ayant chacune une extrémité reliée selon une articulation 54 à une extrémité d'une biellette 10 dont l'extrémité opposée est reliée de façon articulée à un second levier 11 au moyen d'une articulation comprenant un axe 12 porté par le second levier 11 et engagé dans une lumière oblongue 13 réalisée dans la biellette et s'étendant selon la direction longitudinale de la biellette. L'axe 12 et la lumière 13 réalisent ainsi pour chaque biellette un jeu selon une direction longitudinale de la biellette.In the illustrated embodiment, the handle 1 is hollow. The handle operating mechanism comprises a first lever 6 having the general shape of a Y comprising a tail 7 arched towards the inside of the handle and mounted in an articulated manner on an axis 8 carried by the handle, and two branches 9 symmetrical by relative to a median plane extending in a longitudinal direction of the handle, and each having one end connected along an articulation 54 to one end of a connecting rod 10, the opposite end of which is connected in an articulated manner to a second lever 11 at the means of a joint comprising a pin 12 carried by the second lever 11 and engaged in an oblong slot 13 made in the connecting rod and extending in the longitudinal direction of the connecting rod. The pin 12 and the slot 13 thus produce for each link a clearance in a longitudinal direction of the link.

A l'extrémité opposée à l'articulation avec la biellette 10, le second levier 11 est monté de façon articulée sur un axe 14 porté par la poignée. L'axe 14 s'étend parallèlement à l'axe 8, à distance de celui-ci selon une direction longitudinale de la poignée.At the end opposite to the articulation with the connecting rod 10, the second lever 11 is mounted in an articulated manner on a shaft 14 carried by the handle. The axis 14 extends parallel to the axis 8, at a distance from the latter in a longitudinal direction of the handle.

Le premier levier 6, le second levier 11 et la biellette 10 réalisent ainsi avec la poignée 1 un quadrilatère déformable dont la déformation provoque un déplacement en translation de la poignée.The first lever 6, the second lever 11 and the connecting rod 10 thus produce with the handle 1 a deformable quadrilateral, the deformation of which causes the handle to move in translation.

Par ailleurs, le mécanisme comprend un organe de manœuvre de serrure de porte comprenant une plaque 15 montée pour pivoter autour d'un axe 16 porté par le boîtier 3 et rappelée par un ressort 17 vers une position pour laquelle un bord de la plaque 15 est mis en appui contre la face interne du boitier 3. La plaque 15 comporte en outre une fente dans laquelle est engagée une tête 18 d'un câble 19 dont l'extrémité opposée est reliée à la serrure de porte 20 (voir figure 6). À la position de repos de la poignée 1 correspond un état de fermeture de la serrure 20.Furthermore, the mechanism comprises a door lock operating member comprising a plate 15 mounted to pivot about an axis 16 carried by the case 3 and returned by a spring 17 to a position for which one edge of the plate 15 bears against the internal face of the case 3. The plate 15 further comprises a slot in which is engaged a head 18 of a cable 19, the opposite end of which is connected to the door lock 20 (see figure 6 ). The rest position of the handle 1 corresponds to a closed state of the lock 20.

Le premier levier 6 comporte également un bras de manœuvre 21 dont l'extrémité s'étend en regard d'un bord de la plaque 15. À l'extrémité inférieure de ce bord, la plaque 15 comporte un ergot de manœuvre 22 dont la fonction sera décrite ci-dessous.The first lever 6 also comprises an operating arm 21 whose end extends opposite an edge of the plate 15. At the lower end of this edge, the plate 15 comprises an operating lug 22 whose function will be described below.

En regard d'une extrémité du levier 11 opposées à l'axe de pivotement 14 du second levier 11 par rapport à la poignée 1, le mécanisme comporte un organe de déploiement, ici une came 23 montée de façon excentrique sur un axe 24 porté par un moteur 25 fixé dans le boîtier et relié à une unité de commande 26 apte à recevoir des signaux de commande de déploiement d'une télécommande 27.Opposite one end of the lever 11 opposite the pivot axis 14 of the second lever 11 relative to the handle 1, the mechanism comprises a deployment member, here a cam 23 mounted eccentrically on an axis 24 carried by a motor 25 fixed in the casing and connected to a control unit 26 capable of receiving deployment control signals from a remote control 27.

Par ailleurs, la serrure 20 comporte un élément de verrouillage de serrure rendu actif lorsque la poignée est dans la position de repos.Furthermore, the lock 20 comprises a lock locking element made active when the handle is in the rest position.

Le fonctionnement du mécanisme selon invention est le suivant : des ressorts 28 sont convenablement disposés entre les leviers et le boîtier pour qu'en association avec le ressort de rappel 17, l'appui du bras de manœuvre 21 sur le bord de la plaque 15 et l'appui de l'extrémité du levier 11 sur l'organe de déploiement 23, l'ensemble soit maintenu dans une position stable pour laquelle la poignée 1 affleure l'ouverture 5, comme illustré sur la figure 2.The operation of the mechanism according to the invention is as follows: springs 28 are suitably arranged between the levers and the housing so that, in association with the return spring 17, the support of the operating arm 21 on the edge of the plate 15 and the support of the end of the lever 11 on the deployment member 23, the assembly is maintained in a stable position for which the handle 1 is flush with the opening 5, as illustrated in the figure 2 .

Lorsqu'un signal de commande de déploiement est envoyé au moteur électrique 25 par unité de commande 26, l'organe de déploiement 23 est entraîné en rotation comme illustré par la flèche 29 sur la figure 3 de sorte que les leviers 6 et 11 sont basculés comme indiqué par les flèches 30 et 31 sur la figure 3. Dans ce mouvement la poignée 1 se déplace en translation comme indiqué par les flèches 32, jusqu'à ce que le bras de manœuvre 21 soit en appui contre l'ergot de manœuvre 22. Simultanément un signal de déverrouillage est envoyé à un organe de déverrouillage électrique 34 associé à la serrure 20. A partir de cette position, une traction effectuée sur la poignée comme indiqué par la flèche 33 sur la figure 4 fait basculer la plaque 15 comme indiqué par la flèche 34 sur la figure 4 de sorte qu'une traction est exercée sur le câble 19 qui ouvre la serrure 20 de la porte.When a deployment control signal is sent to the electric motor 25 by control unit 26, the deployment member 23 is driven in rotation as illustrated by the arrow 29 on the figure 3 so that the levers 6 and 11 are tilted as indicated by the arrows 30 and 31 on the figure 3 . In this movement the handle 1 moves in translation as indicated by the arrows 32, until the operating arm 21 bears against the operating pin 22. Simultaneously an unlocking signal is sent to an unlocking member electric 34 associated with the lock 20. From this position, a traction carried out on the handle as indicated by the arrow 33 on the figure 4 tilts the plate 15 as indicated by the arrow 34 on the figure 4 so that a traction is exerted on the cable 19 which opens the lock 20 of the door.

Dans le cas où le fonctionnement électrique est défaillant, un appui manuel sur la poignée à l'aplomb de l'axe 14 provoque un léger basculement du levier 6, suffisant pour engager la main dans la poignée et exercer une traction sur celle-ci.In the event that the electrical operation is faulty, pressing manually on the handle plumb with the shaft 14 causes a slight tilting of the lever 6, sufficient to engage the hand in the handle and exert traction thereon.

Simultanément il est nécessaire d'assurer un déverrouillage de la serrure.Simultaneously it is necessary to ensure unlocking of the lock.

A cet effet, le mécanisme selon l'invention comprend un dispositif de déverrouillage comportant un cylindre 37 porté par un support directement ou indirectement fixé à la porte, ici une bague 40 fixée dans le boîtier et dans laquelle le cylindre 37 est maintenu bloqué par une vis 41 vissée dans la bague 40 et dont l'extrémité prend appui dans une gorge 39 du cylindre 37. La vis 41 est de préférence disposée pour être accessible depuis la feuillure de la porte, en passant un tournevis dans un tube 51 qui débouche dans la feuillure de la porte. Le cylindre 37 comporte une ouverture 38 pour l'introduction d'une clé 55. Le cylindre 37 est relié à l'élément de déverrouillage 35 de la serrure par l'intermédiaire d'un organe de manœuvre, ici un levier de verrou 42 monté pour pivoter sur un axe 43 porté par le boîtier et relié à l'organe de déverrouillage 36 par un câble 44.To this end, the mechanism according to the invention comprises an unlocking device comprising a cylinder 37 carried by a support directly or indirectly fixed to the door, here a ring 40 fixed in the housing and in which the cylinder 37 is kept blocked by a screw 41 screwed into the ring 40 and the end of which rests in a groove 39 of the cylinder 37. The screw 41 is preferably arranged to be accessible from the rebate of the door, by passing a screwdriver through a tube 51 which opens into the door frame. The cylinder 37 has an opening 38 for the introduction of a key 55. The cylinder 37 is connected to the unlocking element 35 of the lock via an operating member, here a lock lever 42 mounted to pivot on a pin 43 carried by the housing and connected to the unlocking member 36 by a cable 44.

Dans le mode de réalisation de la figure 7 le levier de verrou 42 est relié au cylindre 37 par un organe d'accouplement comprenant un engrenage conique mâle 45 porté par le cylindre 37, et un engrenage conique femelle 46 porté par le levier de verrou 42.In the embodiment of the figure 7 the lock lever 42 is connected to the cylinder 37 by a coupling member comprising a male bevel gear 45 carried by the cylinder 37, and a female bevel gear 46 carried by the lock lever 42.

L'organe d'accouplement a ainsi un axe d'entrée 52 et un axe de sortie 53 qui s'étendent dans deux directions différentes. Par un choix approprié de la direction de l'axe de sortie on peut donc adapter l'accouplement à l'agencement des différents éléments contenus dans le boitier.The coupling member thus has an input axis 52 and an output axis 53 which extend in two different directions. By an appropriate choice of the direction of the output axis, the coupling can therefore be adapted to the arrangement of the various elements contained in the box.

Dans le mode de réalisation de la figure 8, l'engrenage femelle 46 est porté par une platine 47 reliée au levier de verrou 42 par un montage de cardan comprenant un levier 48 portant à chacune de ses extrémités une rotule 49 engagée dans un support de rotule 50.In the embodiment of the figure 8 , the female gear 46 is carried by a plate 47 connected to the lock lever 42 by a universal joint assembly comprising a lever 48 carrying at each of its ends a ball joint 49 engaged in a ball joint support 50.

Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et est susceptible de variantes de réalisation qui apparaîtront à l'homme de métier sans sortir du cadre de l'invention telle que définie par les revendications.Of course, the invention is not limited to the embodiment described and is susceptible to variant embodiments which will become apparent to those skilled in the art without departing from the scope of the invention as defined by the claims.

En particulier, bien que dans le mode de réalisation préféré de l'invention le cylindre 37 soit introduit par la face avant de la porte, ce qui permet d'effectuer des finitions avant de mettre le cylindre 37 en place, il est intéressant de faire déboucher le cylindre 37 derrière la poignée 1 afin de protéger le mécanisme associé à la clé 55 contre un encrassement.In particular, although in the preferred embodiment of the invention the cylinder 37 is introduced through the front face of the door, which makes it possible to carry out finishing touches before putting the cylinder 37 in place, it is interesting to make unclog cylinder 37 behind handle 1 in order to protect the mechanism associated with key 55 against fouling.
