Description

DISPOSITIF DE FERMETURE DU BORD ARRIERE D'UNE PORTE COULISSANTE DE VEHICULE DEVICE FOR CLOSING THE REAR EDGE OF A SLIDING VEHICLE DOOR
La présente invention est relative à un dispositif complémentaire de fermeture du bord arrière d'une porte coulissante latérale de véhicule dont la serrure commandant son ouverture et sa fermeture se situe généralement au milieu de son bord avant.The present invention relates to a complementary device for closing the rear edge of a side sliding vehicle door, the lock controlling its opening and closing is generally located in the middle of its front edge.
Lors de sa fermeture, une telle porte effectue d'abord une translation le long de la paroi latérale de ce véhicule, et ce vers l'avant telle que considérée par rapport au sens de déplacement du véhicule. En fin de course, cette porte effectue une translation latérale vers l'intérieur, en suivant un arc-de-cercle, pour rentrer dans son cadre et s'y verrouiller.When closed, such a door first performs a translation along the side wall of this vehicle, and this forward as considered with respect to the direction of movement of the vehicle. At the end of the race, this door performs a lateral translation inward, following an arc, to enter its frame and lock there.
Pour assurer cette mobilité en translation de la porte, celle-ci est usuellement accrochée en plusieurs points ou bras internes de support de porte à des chariots pendulaires mobiles dans des rails de support : rails supérieur ou inférieur du cadre se prolongeant à l'intérieur du véhicule et/ou rail médian extérieur.To ensure this mobility in translation of the door, the latter is usually hung at several points or internal arms of the door support on pendular carriages movable in support rails: upper or lower rails of the frame extending inside the vehicle and / or outside center rail.
Un ou plusieurs galets de guidage solidaires du bord frontal de la porte, ou de ses bras, sont eux mobiles dans des seconds rails intérieurs de guidage présentant, en fin de course, une partie oblique ou coudée conduisant ce bord contre le montant avant du cadre. Le bord arrière de la porte peut être conduit de manière similaire. En alternative, le chariot du rail extérieur est relié au bord arrière de la porte par un bras articulé qui, lorsque ce chariot arrive en butée de fin de course, effectue une rotation engageant alors ce bord arrière dans le montant en correspondance du cadre.One or more guide rollers integral with the front edge of the door, or its arms, are mobile in second inner guide rails having, at the end of the race, an oblique or bent part leading this edge against the front upright of the frame . The rear edge of the door can be driven similarly. As an alternative, the trolley of the outer rail is connected to the rear edge of the door by an articulated arm which, when this trolley arrives at the end-of-travel stop, performs a rotation then engaging this rear edge in the amount corresponding to the frame.
De nombreux dispositifs, tels que ceux décrits dans les documents DE-A-1 930 485, EP-A-0 478 536 ou WO 93/17211 , ont été développés pour automatiser l'ouverture et la fermeture de telles portes coulissantes. Ces dispositifs comprennent généralement au moins un actuateur linéaire monté parallèlement le long de l'un des rails, cet actuateur se présentant sous la forme d'un vérin hydraulique ou d'une vis sans fin tournée par un moteur électrique et engagé dans un taraudage traversant d'un chariot mobile. L'extrémité mobile de cet actuateur est reliée directement, ou au travers d'une biellette de débattement latéral, au bord frontal de la porte ou en son bras ou chariot de support en correspondance.Many devices, such as those described in documents DE-A-1 930 485, EP-A-0 478 536 or WO 93/17211, have been developed to automate the opening and closing of such sliding doors. These devices generally include at least one linear actuator mounted parallel along one of the rails, this actuator being in the form of a hydraulic cylinder or a worm screw turned by an electric motor and engaged in a through thread. of a mobile cart. The movable end of this actuator is connected directly, or through a lateral travel link, to the front edge of the door or in its corresponding arm or support carriage.
L'un des problèmes de ces dispositifs est que la résistance due à la compression des garnitures d'étanchéité de la porte doit être surmontée dans la phase finale dirigée vers l'intérieur du mouvement de translation de fermeture. Ceci implique, alors, une poussée de la porte dans son cadre avec une certaine vitesse minimum de façon à surmonter cette résistance grâce à l'inertie de cette porte.One of the problems with these devices is that the resistance due to the compression of the door seals must be overcome in the final phase directed towards the inside of the closing translation movement. This implies, then, a push of the door in its frame with a certain minimum speed so as to overcome this resistance thanks to the inertia of this door.
Toutefois, pour des considérations de sécurité, on ne peut envisager une vitesse de déplacement trop importante pour un dispositif automatique, celui-ci devant pouvoir être arrêté instantanément en cas d'obstacle. De plus, le renforcement du vérin de déplacement, ou autre dispositif de mise en mouvement, ne peut résoudre entièrement ce problème du fait que la direction de la force appliquée est essentiellement parallèle au plan de la porte, alors que le mouvement de fermeture en phase finale est surtout perpendiculaire à ce plan.However, for safety considerations, it is not possible to envisage a movement speed which is too high for an automatic device, the latter having to be able to be stopped instantly in the event of an obstacle. In addition, the reinforcement of the displacement cylinder, or other device for setting in motion, cannot entirely solve this problem because the direction of the applied force is essentially parallel to the plane of the door, while the closing movement in phase final is especially perpendicular to this plane.
Pour obvier ce problème, on connaît des dispositifs complémentaires rattrapant un tenon situé sur un bord de la porte lorsque celle-ci arrive en phase finale de fermeture, et forçant cette partie de porte fermement dans la partie correspondante du cadre.To obviate this problem, additional devices are known which take up a tenon situated on an edge of the door when the latter reaches the final closing phase, and force this part of the door firmly into the corresponding part of the frame.
Le document EP 0 157 391 décrit un tel dispositif basé sur une coupelle montée mobile en rotation sur la tranche de la porte au-dessus ou en dessous de la serrure en étant entraînée en rotation par un moteur également installé dans la porte, cette coupelle portant une came en spirale interagissant avec un tenon du cadre. Toutefois, cette coupelle étant directement actionnée par le moteur, il convient de prévoir un dispositif additionnel basé sur un crochet mobile verticalement pour fixer la position angulaire de repos de cette coupelle où elle n'interfère plus avec le tenon. Ce dispositif connu est donc relativement complexe.Document EP 0 157 391 describes such a device based on a cup mounted mobile in rotation on the edge of the door above or below the lock while being driven in rotation by a motor also installed in the door, this cup carrying a spiral cam interacting with a tenon of the frame. However, this cup being directly actuated by the motor, it is advisable to provide an additional device based on a vertically movable hook to fix the angular position of rest of this cup where it no longer interferes with the tenon. This known device is therefore relatively complex.
D'autres dispositifs connus pour véhicule automobile, par exemple ceux décrits dans le document EP 0 467 057 et WO 89/02964, sont basés sur un tenon de porte monté de manière excentrée sur un arbre de sortie d'un moteur, ce qui permet de les inclure directement dans la serrure de porte. Ainsi, dès que la fourche de la serrure a crocheté le tenon, celui-ci effectue un demi-tour, ce qui tire la porte dans son cadre. Ces dispositifs sont également complexes, adaptables que dans des serrures pré-existantes, et leur course de rattrapage est généralement plutôt faible.Other known devices for a motor vehicle, for example those described in document EP 0 467 057 and WO 89/02964, are based on a door lug mounted eccentrically on an output shaft of an engine, which allows to include them directly in the door lock. Thus, as soon as the fork of the lock has hooked the stud, the latter makes a U-turn, which pulls the door in its frame. These devices are also complex, adaptable only in pre-existing locks, and their catch-up stroke is generally rather small.
Le document GB 2 140 501 divulgue un dispositif de fermeture du bord arrière d'une porte coulissante latérale de véhicule qui comprend un tenon fixé à la porte et un doigt commandé en rotation par un axe relié à un moteur. Le tenon et le doigt sont disposés dans un même plan perpendiculaire à l'axe de rotation. Cet agencement permet d'insérer la porte dans son cadre, à condition que cette dernière se trouve très proche du cadre. La porte est battante et non pas coulissante, ce qui suppose qu'elle puisse toujours être approchée suffisamment près du cadre du véhicule.The document GB 2 140 501 discloses a device for closing the rear edge of a side sliding vehicle door which comprises a lug fixed to the door and a finger controlled in rotation by a pin connected to a motor. The tenon and the finger are arranged in the same plane perpendicular to the axis of rotation. This arrangement allows the door to be inserted into its frame, provided that the latter is very close to the frame. The door is hinged and not sliding, which means that it can always be approached close enough to the vehicle frame.
Les documents EP 0 312 958 et EP 0 262 052 se rapportent à des dispositifs de verrouillage d'une serrure montée sur la porte d'un véhicule, et non pas à des dispositifs de fermeture de la porte dans son cadre, avant le verrouillage de celle-ci.The documents EP 0 312 958 and EP 0 262 052 relate to locking devices for a lock mounted on the door of a vehicle, and not to devices for closing the door in its frame, before the locking of this one.
Le but de la présente invention est un dispositif complémentaire de fermeture du bord arrière d'une porte coulissante latérale de véhicule permettant d'obvier le problème mentionné précédemment. Un tel dispositif doit notamment être suffisamment puissant pour assurer de manière fiable l'insertion complète d'une porte latérale coulissante dans son cadre, et ceci pratiquement en toutes circonstances quand bien même cette porte n'est amenée qu'avec une faible vitesse. La puissance nécessaire d'entraînement doit toutefois être raisonnable pour ne pas impliquer de moteur trop encombrant. De préférence, ce dispositif doit également présenter une conception relativement simple pour augmenter sa fiabilité, pour faciliter et limiter son entretien, et en diminuer son coût.The object of the present invention is a complementary device for closing the rear edge of a sliding side door of a vehicle making it possible to obviate the problem mentioned above.

The necessary drive power must however be reasonable so as not to involve a motor that is too bulky. Preferably, this device must also have a relatively simple design to increase its reliability, to facilitate and limit its maintenance, and to reduce its cost.
Ces buts sont atteints, selon l'invention, grâce à un dispositif de fermeture du bord arrière d'une porte coulissante latérale de véhicule comprenant :These aims are achieved, according to the invention, thanks to a device for closing the rear edge of a side sliding door of a vehicle comprising:

- des moyens électromécaniques aptes à entraîner la pièce en une rotation alternative à partir d'une position de repos dans laquelle le doigt se situe hors du trajet de déplacement du tenon, de telle sorte que, dans le premier sens, le doigt vient accrocher le tenon pour tirer la porte dans son cadre, puis en sens inverse de telle sorte que le doigt revienne en position de repos, ou inversement, d'une part le tenon protubérant du cadre, d'autre part la pièce rotative muni du doigt et les moyens électromécaniques appartenant à la porte, - ainsi que des moyens de détection de l'arrivée de la porte proche du cadre, ces moyens de détection déclenchant un cycle des moyens d'entraînement électromécaniques, caractérisé en ce que l'axe de rotation est parallèle mais décalé par rapport à celui du tenon lorsque la porte est en position de fermeture.- electromechanical means capable of driving the part in an alternating rotation from a rest position in which the finger is located outside the path of movement of the tenon, so that, in the first direction, the finger hooks the post to pull the door in its frame, then in the opposite direction so that the finger returns to the rest position, or vice versa, on the one hand the protruding post of the frame, on the other hand the rotating part provided with the finger and the electromechanical means belonging to the door, - as well as means for detecting the arrival of the door close to the frame, these detection means triggering a cycle of the electromechanical drive means, characterized in that the axis of rotation is parallel but offset from that of the tenon when the door is in the closed position.
Ce dispositif, basé sur un mouvement naturellement simple d'un doigt venant pousser un tenon pour amener et forcer la porte dans son cadre, puis revenir en position de repos, permet une construction et une installation simplifiée, donc un coût raisonnable. Ce dispositif autonome peut notamment être rapporté sur un véhicule déjà utilisé. La position plus ou moins décalée de l'axe de rotation du doigt permet d'assurer un débattement suffisant de celui-ci pour qu'il rattrape de manière simple et fiable une porte s'arrêtant assez loin de son cadre. Le déplacement en sens inverse du doigt peut être immédiat, ou ne s'effectuer qu'ultérieurement, par exemple lors de la commande de réouverture de la porte, ce dispositif constituant alors un moyen de maintien complémentaire de la porte en position fermée.This device, based on a naturally simple movement of a finger pushing a tenon to bring and force the door into its frame, then return to the rest position, allows a simplified construction and installation, therefore a reasonable cost. This autonomous device can in particular be attached to an already used vehicle. The more or less offset position of the axis of rotation of the finger ensures sufficient clearance of the latter so that it catches in a simple and reliable manner a door stopping far enough from its frame. The movement in the opposite direction of the finger may be immediate, or may only be carried out subsequently, for example during the reopening of the door command, this device then constituting a means of complementary holding of the door in the closed position.
Selon un mode de réalisation préféré, la pièce rotative est un axe monté dans un ou plusieurs supports de type paliers contre la paroi latérale arrière du véhicule, respectivement paroi arrière de la porte, dont l'extrémité émergeant dans le cadre porte le doigt, et dont l'autre extrémité porte un bras oscillant perpendiculaire à cet axe, les moyens d'entraînement électromécaniques appliquant à l'extrémité de ce bras oscillant, au travers d'une articulation, un déplacement alternatif sensiblement en translation.According to a preferred embodiment, the rotary part is an axis mounted in one or more bearing type supports against the rear side wall of the vehicle, respectively rear wall of the door, the end of which emerges in the frame carries the finger, and the other end of which carries an oscillating arm perpendicular to this axis, the electromechanical drive means applying to the end of this oscillating arm, through an articulation, an alternative movement substantially in translation.
Par articulation, on entend une liaison assurant un certain degré de liberté, soit en rotation autour d'un point de pivot telle qu'une rotule, soit en translation limitée au sein d'une ouverture oblongue ou d'une glissière le long de ce bras. Avantageusement, ce bras oscillant présentent une pluralité de points d'accrochage de l'articulation de fixation de la bielle, permettant ainsi de régler le couple de forces transmis.By articulation is meant a connection ensuring a certain degree of freedom, either in rotation around a pivot point such as a ball joint, or in limited translation within an oblong opening or a slide along this arms. Advantageously, this oscillating arm has a plurality of attachment points for the connecting rod fixing articulation, thus making it possible to adjust the torque of forces transmitted.
Ce bras oscillant permet de convertir un déplacement sensiblement en translation verticale des moyens d'entraînement en une rotation alternative de l'axe dans une plage angulaire par exemple de 90 à 120°, de préférence 110°, cette rotation transmise au doigt lui permettant de pousser le tenon de porte. Un grand avantage de cet agencement est que l'on peut facilement démultiplier le couple mécanique transmis en augmentant plus ou moins la longueur de ce bras oscillant par rapport au rayon d'action du doigt. Ceci permet d'adapter ce dispositif à une plus grande gamme de véhicule. Un autre avantage de ce dispositif est que l'on peut utiliser une pluralité de moyens d'entraînement en translation disponibles sur le marché, tel que des vérins.This oscillating arm makes it possible to convert a displacement substantially in vertical translation of the drive means into an alternative rotation of the axis in an angular range for example from 90 to 120 °, preferably 110 °, this rotation transmitted to the finger allowing it to push the door post. A great advantage of this arrangement is that one can easily multiply the mechanical torque transmitted by more or less increasing the length of this oscillating arm relative to the radius of action of the finger. This allows this device to be adapted to a wider range of vehicles. Another advantage of this device is that one can use a plurality of translational drive means available on the market, such as jacks.
De préférence, les moyens d'entraînement sensiblement en translation de l'extrémité du bras oscillant comprennent une bielle reliée d'une part à cette extrémité de bras oscillant, de préférence par une rotule, et reliée d'autre part, également de préférence par une rotule, à l'une des extrémités d'un bras rotatif dont l'autre extrémité est solidaire de l'arbre de sortie d'un motoréducteur couplé au moyen de détection de l'arrivée de la porte.Preferably, the means for driving substantially in translation of the end of the swinging arm comprise a connecting rod connected on the one hand to this end of the swinging arm, preferably by a ball joint, and connected on the other hand, also preferably by a ball joint at one end of a rotary arm, the other end of which is integral with the output shaft of a gearmotor coupled to the means for detecting the arrival of the door.
Par motoréducteur, on entend un moteur électrique dont l'arbre de sortie est relié à un engrenage démultipliant le nombre de tours pour augmenter le couple et/ou la force de sortie.By geared motor is meant an electric motor whose output shaft is connected to a gear multiplying the number of revolutions to increase the torque and / or the output force.
Dans le domaine de la construction automobile, on dispose déjà d'un certain nombre de motoréducteurs connus et fiables, tel que des motoréducteurs d'entraînement de vitres électriques ou d'essuie-glace. Cet agencement par bielle permet ainsi de mettre en oeuvre de manière simple ce type de motoréducteur. Un autre avantage vient du fait qu'une imprécision de la position finale angulaire après un tour complet de l'arbre de sortie du motoréducteur en fin de cycle se traduit que par une erreur minime dans la position de repos du doigt d'actionnement, ce qui évite un dispositif d'ajustement ce cette valeur de repos. Avantageusement, le bras rotatif présente une pluralité de points d'accrochage de l'articulation de la bielle permettant de régler l'amplitude du mouvement rotatif alternatif et/ou le couple de forces transmis au doigt.In the field of automobile construction, a number of known and reliable geared motors are already available, such as geared motors for driving electric windows or wipers. This connecting rod arrangement thus makes it possible to implement this type of geared motor in a simple manner. Another advantage comes from the fact that an imprecision of the final angular position after a complete revolution of the output shaft of the gearmotor at the end of the cycle results in only a minimal error in the rest position of the actuating finger, this which avoids a device for adjusting this rest value. Advantageously, the rotary arm has a plurality of attachment points for the articulation of the connecting rod making it possible to adjust the amplitude of the alternating rotary movement and / or the torque of forces transmitted to the finger.
Avantageusement encore, la bielle est constituée d'un amortisseur télescopique à gaz et/ou à ressort. Cette bielle-amortisseur introduit dans la cinématique du dispositif un élément élastique rendant superflu tout réglage au sein de la cinématique absorbant d'éventuelles contraintes mécaniques, par exemple dues à un blocage imprévu de la porte de par la présence d'un objet dans le cadre. Cette bielle-amortisseur prolonge ainsi sensiblement la durée de vie et la fiabilité du dispositif.Advantageously also, the connecting rod consists of a telescopic gas and / or spring shock absorber. This shock absorber rod introduces an elastic element into the kinematics of the device, making any adjustment in the kinematics superfluous absorbing any mechanical stresses, for example due to an unexpected blocking of the door due to the presence of an object in the frame. . This shock absorber rod thus significantly extends the life and reliability of the device.
L'invention sera mieux comprise à l'étude d'un mode de réalisation pris à titre d'exemple nullement limitatif et illustré schématiquement en perspective dans la figure annexée.The invention will be better understood from the study of an embodiment taken by way of nonlimiting example and illustrated diagrammatically in perspective in the appended figure.
La figure annexée illustre une portion de paroi latérale externe 12 de châssis d'un véhicule, par exemple un minibus de transport de passagers, présentant un cadre 16 dans lequel vient se fermer une porte coulissante 10 d'accès à ce véhicule. Typiquement, une telle porte est agencée dans la paroi latérale droite du véhicule, plutôt en avant, faisant que la figure annexée illustre la partie arrière de cette porte 10 telle que vue en retrait du côté droit et en arrière du véhicule. La paroi externe 12 peut être complétée par une seconde portion de paroi interne 12b agencée en vis-à-vis.The appended figure illustrates a portion of the external lateral wall 12 of the chassis of a vehicle, for example a passenger transport minibus, having a frame 16 in which a sliding door 10 for access to this vehicle is closed. Typically, such a door is arranged in the right side wall of the vehicle, rather in front, so that the appended figure illustrates the rear part of this door 10 as viewed back from the right side and behind the vehicle. The outer wall 12 can be completed by a second portion of the inner wall 12b arranged opposite.
Notamment, lors de sa fermeture, cette porte 10 effectue d'abord une translation T dirigée vers l'avant du véhicule en suivant des rails de support et de guidage non illustrés puis, par un mouvement de translation Tr suivant une ligne oblique ou un arc-de-cercle, effectue un déplacement orientée vers l'intérieur du véhicule pour rentrer dans le cadre 16 et s'appuyer contre des joints d'étanchéité. Le déplacement de cette porte est, dans le cadre de cette invention, automatisé par un dispositif d'entraînement, par exemple tel que celui décrit dans le document WO 93/17211 de la demanderesse dont le contenu fait partie de la présente description en vertu de cette citation.In particular, when it is closed, this door 10 first performs a translation T directed towards the front of the vehicle by following support and guide rails not shown, then, by a translation movement Tr along an oblique line or an arc -de-circle, makes a movement oriented towards the interior of the vehicle to enter the frame 16 and lean against seals. The movement of this door is, in the context of this invention, automated by a drive device, for example such as that described in document WO 93/17211 of the applicant, the content of which forms part of the present description by virtue of this quotation.
Plus particulièrement selon l'invention, la tranche arrière de la porte 10 est munie d'un tenon 20 sensiblement horizontal et orienté vers l'arrière dans le plan de cette porte 10. Tel qu'illustré, ce tenon 20 peut appartenir à une plaque de support 22 elle-même boulonnée ou soudée contre la tranche de cette porte.More particularly according to the invention, the rear edge of the door 10 is provided with a substantially horizontal lug 20 and oriented rearwards in the plan of this door 10. As illustrated, this tenon 20 may belong to a support plate 22 itself bolted or welded against the edge of this door.
Comme illustré, un support tubulaire 34 est tenu rigidement par une fixation 36 contre la face interne de la paroi verticale latérale externe 12 ou contre la face externe de la paroi interne 12b du véhicule, et ceci sensiblement horizontalement peu en dessous du tenon 20. Ce support tubulaire 34 a une fonction de palier de support pour un axe rotatif interne 32 dont l'extrémité émergeant dans le cadre 16 de porte présente un doigt perpendiculaire 30.As illustrated, a tubular support 34 is rigidly held by a fixing 36 against the internal face of the external lateral vertical wall 12 or against the external face of the internal wall 12b of the vehicle, and this substantially horizontally slightly below the lug 20. This tubular support 34 has a support bearing function for an internal rotary axis 32 whose end emerging in the door frame 16 has a perpendicular finger 30.
Comme bien visible sur la figure, ce doigt 30 se retrouve, en position de repos, sensiblement à l'horizontale, sous le tenon 20, et perpendiculaire à l'axe rotatif 32 donc également perpendiculairement à l'axe du tenon 20. Ce doigt 30 peut être paralléllépipédique allongé ou, comme illustré, présenter une forme arquée en direction du tenon 20.As clearly visible in the figure, this finger 30 is found, in the rest position, substantially horizontally, under the tenon 20, and perpendicular to the rotary axis 32 therefore also perpendicular to the axis of the tenon. This finger 30 can be an elongated parallelepiped or, as illustrated, have an arcuate shape in the direction of the tenon 20.
L'extrémité de l'axe 32 opposée au doigt 30 porte un bras oscillant 40 perpendiculaire et sensiblement horizontal. Dans l'exemple illustré, ce bras 40 est orienté du même côté que le doigt 30, étant bien entendu qu'il pourrait, dans le cadre de l'invention, également être orienté toujours sensiblement à l'horizontale, du côté diamétralement opposé par rapport à l'axe 32.The end of the axis 32 opposite the finger 30 carries an oscillating arm 40 perpendicular and substantially horizontal. In the example illustrated, this arm 40 is oriented on the same side as the finger 30, it being understood that it could, in the context of the invention, also be oriented always substantially horizontally, on the side diametrically opposite by relative to axis 32.
L'extrémité du doigt 40 est reliée par une articulation 52 à l'extrémité supérieure d'une bielle télescopique 50 dont l'extrémité inférieure est reliée par une articulation 54 à l'une des extrémités d'un bras rotatif 60 dont l'autre extrémité est solidaire de l'arbre de sortie d'un motoréducteur 70.The end of the finger 40 is connected by a hinge 52 to the upper end of a telescopic rod 50, the lower end of which is connected by a hinge 54 to one of the ends of a rotary arm 60, the other of which end is integral with the output shaft of a geared motor 70.
Comme mieux visible sur la figure, le bras oscillant 40 présente une pluralité d'orifices 42 de positionnement de l'articulation 52 de fixation de la bielle 50. De manière analogue, le bras rotatif 60 présente, en son extrémité radiale, une pluralité de points d'accrochage 62 de l'autre extrémité de la bielle 50.As best seen in the figure, the oscillating arm 40 has a plurality of orifices 42 for positioning the articulation 52 for fixing the connecting rod 50. Similarly, the rotary arm 60 has, at its radial end, a plurality of attachment points 62 on the other end of the connecting rod 50.
De préférence, la bielle 50 est constituée par un amortisseur télescopique à gaz et/ou ressort constituant un élément élastique dans la cinématique de ce dispositif.Preferably, the connecting rod 50 is constituted by a telescopic gas shock absorber and / or spring constituting an elastic element in the kinematics of this device.
Le dispositif décrit précédemment fonctionne de la manière suivante. La figure annexée illustre le dispositif dans sa position de repos correspondant notamment à un moment où la porte 10 est ouverte. Dans cette situation, le bras rotatif 60 est en position verticale orienté vers le bas faisant que le bras oscillant 40 est tiré vers le bas ce qui oriente le doigt 30 solidaire de l'autre extrémité de l'axe 32 sensiblement à l'horizontale, c'est-à-dire en une position n'interférant pas avec le trajet du tenon 20 lors de l'ouverture et de la fermeture de la porte 10.The device described above operates in the following manner. The appended figure illustrates the device in its rest position corresponding in particular to a moment when the door 10 is open. In this situation, the rotary arm 60 is in a vertical position facing downwards so that the swinging arm 40 is pulled downwards which directs the finger 30 secured to the other end of the axis 32 substantially horizontally, that is to say in a position which does not interfere with the path of the tenon 20 when the door 10 is opened and closed.
Des moyens de détection non illustrés appliquent un signal électrique au motoréducteur 70 lorsque le dispositif d'entraînement automatique de la porte 10 lui a fait effectuer la translation en avant T et a enclenché la phase finale de déplacement Tr en translation vers l'intérieur du véhicule.Detection means not illustrated apply an electrical signal to the gearmotor 70 when the automatic drive device of the door 10 has made it perform the forward translation T and has engaged the final phase of movement Tr in translation towards the interior of the vehicle .
Cette impulsion de commande déclenche une première phase pendant laquelle l'arbre de sortie du motoréducteur 70 effectue un demi-tour ce qui amène le bras rotatif 60 en position verticale. Le sens de rotation du motoréducteur 70 est indifférent. Pendant le demi-tour du bras rotatif 60, la bielle 50 monte en entraînant avec elle le bras oscillant 40 qui effectue une rotation dans le sens inverse des aiguilles d'une montre tel que vu sur la figure, entraînant dans le même sens le doigt 30.This control pulse triggers a first phase during which the output shaft of the gearmotor 70 makes a U-turn which brings the rotary arm 60 to the vertical position. The direction of rotation of the gearmotor 70 is indifferent. During the half-turn of the rotary arm 60, the connecting rod 50 rises, driving with it the oscillating arm 40 which rotates counterclockwise as seen in the figure, driving the finger in the same direction. 30.
Lors de sa rotation également dans le sens inverse des aiguilles d'une montre, le doigt 30 vient en appui contre la face externe du tenon 20 puis pousse celui-ci vers l'intérieur forçant ainsi le bord arrière de la porte latérale 10 dans le cadre 16.During its rotation also in the anticlockwise direction, the finger 30 comes to bear against the external face of the tenon 20 then pushes the latter inward thus forcing the rear edge of the side door 10 into the frame 16.
Dans la phase suivante, l'arbre de sortie du motoréducteur 70 effectue à nouveau un demi-tour pour amener le bras rotatif 60 en sa position verticale orienté vers le bas tel qu'illustré sur la figure, ce qui tire la bielle 50 vers le bas donc tourne l'axe 32 maintenant dans le sens des aiguilles d'une montre. Le doigt 30 est alors ramené dans sa position horizontale n'interférant plus avec le tenon 20. Si désiré, cette seconde phase peut être retardée jusqu'à la réception d'une nouvelle impulsion représentative d'un ordre d'ouverture de la porte appliquée simultanément au dispositif d'entraînement automatique de cette porte. Dans ce cas, le dispositif complémentaire selon l'invention a assuré le verrouillage de la partie arrière de la porte 10 pendant toute la période où cette porte est également maintenue fermée par la serrure avant. De nombreuses améliorations peuvent être apportées à ce dispositif tel que décrit précédemment. Notamment, le support tubulaire 34 peut être remplacé par un ou plusieurs paliers de support d'axe 32 chacun monté directement contre le châssis du véhicule.In the following phase, the output shaft of the gearmotor 70 again performs a half-turn to bring the rotary arm 60 into its vertical position facing downwards as illustrated in the figure, which pulls the connecting rod 50 towards the down so rotate the axis 32 now clockwise. The finger 30 is then returned to its horizontal position no longer interfering with the lug 20. If desired, this second phase can be delayed until the reception of a new pulse representative of an order to open the door applied simultaneously with the automatic drive device of this door. In this case, the complementary device according to the invention ensured the locking of the rear part of the door 10 throughout the period when this door is also kept closed by the front lock. Many improvements can be made to this device as described above. In particular, the tubular support 34 can be replaced by one or more axle support bearings 32 each mounted directly against the chassis of the vehicle.
On prévoit une bielle-amortisseur dont la course en contraction est supérieure au diamètre parcouru par le bras rotatif 60, de telle sorte qu'un blocage dès son départ du doigt 30 peut entièrement être absorbé par la bielle 50 autorisant un tour complet au motoréducteur.A shock absorber rod is provided, the contraction stroke of which is greater than the diameter traversed by the rotary arm 60, so that a blockage as soon as it leaves the finger 30 can be entirely absorbed by the rod 50 allowing a complete revolution of the gearmotor.
A cet effet, la bielle-amortisseur présente une valeur de seuil de déclenchement de contraction établie en fonction du couple limite du motoréducteur et de la longueur du bras rotatif, par exemple compris entre 400 N et 700 N et plus particulièrement de 500 N.To this end, the shock absorber rod has a contraction trigger threshold value established as a function of the limit torque of the gearmotor and the length of the rotary arm, for example between 400 N and 700 N and more particularly 500 N.
Par ailleurs, le bras oscillant 40 peut présenter une pluralité de points d'accrochage 42 de l'articulation 52 de la bielle 50, permettant de moduler, selon le besoin, le couple de rotations transmis au doigt 30. De manière analogue, le bras rotatif 60 peut présenter une pluralité de points d'accrochage 62 permettant, en relation avec des bielles 50 de différentes longueurs, de moduler l'ampleur de la rotation appliquée à l'axe 32, donc au doigt 30. On peut de plus envisager une possibilité de réglage de la position longitudinale des rotules 52 ou 54 sur la bielle 50.Furthermore, the swinging arm 40 may have a plurality of attachment points 42 of the articulation 52 of the connecting rod 50, making it possible to modulate, as required, the torque of rotations transmitted to the finger 30. Similarly, the arm rotary 60 can have a plurality of attachment points 62 allowing, in relation to connecting rods 50 of different lengths, to modulate the magnitude of the rotation applied to the axis 32, therefore to the finger 30. It is also possible to envisage a possibility of adjusting the longitudinal position of the ball joints 52 or 54 on the connecting rod 50.
Par ailleurs, il n'est nullement nécessaire que le motoréducteur 70 soit agencé parallèlement à l'axe 32 comme illustré sur la figure annexée dès lors que, selon la configuration de ce motoréducteur, il peut être agencé d'une autre manière pour autant que son axe de sortie se situe dans un plan horizontal de telle sorte à tourner le bras rotatif dans un plan vertical.Furthermore, it is not at all necessary for the geared motor 70 to be arranged parallel to the axis 32 as illustrated in the appended figure since, depending on the configuration of this geared motor, it can be arranged in another way provided that its output axis is located in a horizontal plane so as to rotate the rotary arm in a vertical plane.
Selon la place disponible, on peut également envisager d'inverser l'installation de ce dispositif, le tenon 20 appartenant alors au châssis du véhicule, le motoréducteur, la bielle 50, l'axe 32 et le doigt 30 faisant alors partie de la porte 10.Depending on the space available, one can also consider reversing the installation of this device, the lug 20 then belonging to the chassis of the vehicle, the gear motor, the connecting rod 50, the axis 32 and the finger 30 then forming part of the door. 10.
L'illustration du dispositif dans la figure annexée donne un ordre de grandeur du rapport des dimensions des pièces entre elles, étant bien entendu que certaines d'entre elles peuvent être surdimensionnées ou sousdimensionnees selon le besoin.The illustration of the device in the appended figure gives an order of magnitude of the ratio of the dimensions of the parts to each other, it being understood that some of them can be oversized or undersized as needed.
D'autres améliorations peuvent être apportées à ce dispositif dans le cadre des revendications. Other improvements can be made to this device within the scope of the claims.
