Description

La présente invention a pour objet une charnière à arrêt de porte intégré destinée à être montée sur les portes de véhicules automobiles, mais pouvant s'appliquer à tout système comportant des ouvrants. Généralement, la liaison entre la porte et la caisse d'un véhicule est assurée, au moyen de deux charnières, comportant un dispositif appelé « arrêt de porte » dont le but est de limiter la course d'ouverture de la porte et d'assurer deux arrêts à des positions intermédiaires de ladite porte, dites positions de parking et de pleine ouverture.The present invention relates to a stop hinge of integrated door designed to be mounted on the doors of motor vehicles, but can be applied to any system comprising openings. Generally, the bond between the door and the body of a vehicle is ensured, by means of two hinges, comprising a device called "stop of door ”whose purpose is to limit the opening stroke of the door and provide two stops at intermediate positions of said door, say parking and full opening positions.

Lorsque l'on ouvre la porte, on doit produire un effort modéré pour vaincre un faible couple, mais la porte doit être fermement maintenue dans la position dite « ouverture de parking ». Pour ouvrir la porte en position d'ouverture maximum dite « de pleine ouverture » où elle se trouve stoppée par l'arrêt de porte, on doit vaincre un couple beaucoup plus important. Il en est de même pour refermer ladite porte. Entre ces positions, la porte doit en outre pouvoir pivoter librement tout en subissant une légère retenue. Le brevet EP-A-0255879 (LUNKE & SOHN GmbH) décrit une charnière dont l'axe d'articulation est muni dans sa partie centrale de trois bossages coopérant avec trois lames élastiques reposant sur toute leur longueur sur une couche d'élastomère recouvrant l'alésage cylindrique du charnon mobile. La configuration des lames élastiques qui appuient constamment sur les bossages de l'axe d'articulation entraíne leur usure rapide. Le brevet EP-A-0443919 (COMACI) décrit une charnière dont l'axe d'articulation comporte des bossages agissant sur une lame élastique, présentant une protubérance en son milieu. Cette réalisation entraíne une usure rapide du dispositif. La présente invention a pour objet des perfectionnements à de telles charnières à arrêt de porte intégré dont le but essentiel est d'assurer le meilleur maintien de la porte dans les trois positions précitées, au moyen de dispositifs simples, robustes, économiques et assurant une grande longévité auxdites charnières, limitant les réparations ou remplacement.When you open the door, you have to make an effort moderate to overcome a low torque, but the door should be firmly held in the position called "opening of car park ". To open the door to the maximum open position called "full opening" where it is stopped by the door stop, we have to defeat a couple much more important. It is the same to close said door. Between these positions, the door must also be able to pivot freely while undergoing a slight restraint. EP-A-0255879 (LUNKE & SOHN GmbH) describes a hinge whose axis articulation is provided in its central part with three bosses cooperating with three elastic blades resting on their entire length on a layer of elastomer covering the cylindrical bore of the movable knuckle. The configuration of elastic blades that constantly press on the bosses the axis of articulation causes their rapid wear. EP-A-0443919 (COMACI) describes a hinge whose axis of articulation comprises bosses acting on a blade elastic, having a protrusion in the middle. This realization leads to rapid wear of the device. The current invention relates to improvements to such hinges with integrated door stop, the main purpose of which is to ensure the best maintenance of the door in the three aforementioned positions, by means of simple, robust devices, economical and ensuring a great longevity to said hinges, limiting repairs or replacement.

Le document EP-A-0 255 879 décrit une charnière à arrêt de porte intégré présentant les caractéristiques du préambule de la revendication 1.Document EP-A-0 255 879 describes a hinge to integrated door stop with characteristics of the preamble of claim 1.

La charnière à arrêt de porte intégré, selon l'invention, est constituée d'un charnon fixe monté sur la caisse du véhicule et d'un charnon mobile fixé sur la porte, le charnon fixe recevant dans un alésage cylindrique un axe d'articulation muni dans sa partie centrale de bossages destinés à coopérer avec des lames élastiques, chaque lame élastique étant couplée avec une contre lame en métal plus rigide épousant sa forme et la recouvrant partiellement; chaque lame élastique étant conformée de manière telle que l'une de ses extrémités coopère avec les bossages de l'axe d'articulation et repose sur un profilé en élastomère, son autre extrémité étant fixée avec sa contre lame, à l'intérieur de l'alésage au moyen d'une fixation rigide.The hinge with integrated door stop, according to the invention, is consisting of a fixed knuckle mounted on the vehicle body and a movable knuckle fixed on the door, the fixed knuckle receiving in a cylindrical bore a hinge pin provided in its central part of bosses intended to cooperate with elastic blades, each elastic blade being coupled with a stiffer metal counter blade conforming to its shape and partially overlapping; each elastic blade being shaped so that one of its ends cooperates with the bosses of the hinge pin and rests on an elastomer profile, its other end being fixed with its counter blade, inside the bore by means of a rigid fixing.

Sur la figure 1, on a représenté une porte P de véhicule automobile avec ses charnières C1 et C2. La charnière C2 peut être une charnière de type connu, la charnière supérieure C1 étant une charnière selon la présente invention qui va être plus particulièrement décrite en se reportant aux figures 2 à 6.
La charnière à arrêt de porte C1 selon un mode de réalisation de l'invention est constituée d'un charnon fixe 1 monté sur la caisse V du véhicule au moyen d'une bride 1a et d'un charnon mobile 2 fixé sur la porte P du véhicule également au moyen d'une bride 2a de façon connue en soi.
Le charnon fixe 1 comporte un alésage cylindrique 3. Il reçoit un axe d'articulation 6 tournant entre deux paliers 7 et 8 munis de bagues autolubrifiantes 9 et 10. Ces paliers 7 et 8 sont vissés à chaque extrémité de l'alésage 3 du charnon fixe 1 pour permettre le montage de l'axe d'articulation 6.
Cet axe d'articulation 6 comporte une partie centrale de plus grand diamètre, 6a munie de bossages 11 répartis à sa périphérie par groupe de deux.
Entre l'alésage 3 du charnon fixe 1 et l'axe d'articulation 6a sont insérées trois lames élastiques ou ressorts 4 (figures 4 et 5) destinées à coopérer avec les bossages 11 de l'axe d'articulation 6a. Chaque lame élastique ou ressort 4 (figure 6) comporte à son extrémité une partie recourbée 4a destinée à appuyer sur la périphérie de l'axe 6, et à coopérer avec les bossages 11 dudit axe de manière à pouvoir s'insérer entre lesdits bossages. Derrière chaque lame élastique 4 est disposée une contre lame 5 en métal moins flexible. La contre lame 5 épouse la forme de la lame élastique 4, et la recouvre partiellement. Cette contre lame a pour objet de maintenir une certaine pression sur la lame élastique tout en laissant une élasticité à son extrémité 4a et d'obtenir un couple plus important lorsque l'extrémité recourbée 4a de la lame passe sur un bossage 11 de l'axe 6.The invention will be better understood on reading the following description of one of its preferred embodiments given by way of example and on examining the appended drawings in which:
  • Figure 1 is an elevational view of a vehicle door with its hinges according to an embodiment of the invention.
  • Figure 2 is an elevational view of a hinge with integrated door stop, the door closed.
  • Figure 3 is a plan view of Figure 2.

  • Figures 7, 8 and 9 show in section, the hinge axis of the hinge according to the invention in three different positions.
  • Figure 10 is a plan view of the hinge with integrated door stop according to an embodiment of the invention, the door being opened to the maximum.
  • Figure 11 shows, in section, the hinge axis of a hinge with integrated door stop.
  • FIG. 12 is a cross-sectional view of the hinge with integrated door stop according to FIG. 11.
  • Figures 13,14 and 15 show in section, the hinge axis of the hinge of Figure II in three different positions.
In Figure 1, there is shown a door P of a motor vehicle with its hinges C1 and C2. The hinge C2 can be a hinge of known type, the upper hinge C1 being a hinge according to the present invention which will be more particularly described with reference to FIGS. 2 to 6.
The door stop hinge C1 according to one embodiment of the invention consists of a fixed knuckle 1 mounted on the body V of the vehicle by means of a flange 1a and a movable knuckle 2 fixed on the door P of the vehicle also by means of a flange 2a in a manner known per se.
The fixed knuckle 1 has a cylindrical bore 3. It receives a hinge pin 6 rotating between two bearings 7 and 8 provided with self-lubricating rings 9 and 10. These bearings 7 and 8 are screwed at each end of the bore 3 of the knuckle fixed 1 to allow the mounting of the hinge pin 6.
This articulation axis 6 comprises a central part of larger diameter, 6a provided with bosses 11 distributed at its periphery in groups of two.
Between the bore 3 of the fixed knuckle 1 and the hinge pin 6a are inserted three elastic blades or springs 4 (Figures 4 and 5) intended to cooperate with the bosses 11 of the hinge pin 6a. Each elastic blade or spring 4 (FIG. 6) has at its end a curved part 4a intended to press on the periphery of the axis 6, and to cooperate with the bosses 11 of said axis so as to be able to be inserted between said bosses. Behind each elastic blade 4 is arranged a counter blade 5 made of less flexible metal. The counter blade 5 follows the shape of the elastic blade 4, and partially covers it. The purpose of this counter blade is to maintain a certain pressure on the elastic blade while leaving an elasticity at its end 4a and to obtain greater torque when the curved end 4a of the blade passes over a boss 11 of the axis. 6.

Chaque lame 4 et sa contre lame 5 sont fixées sur charnon 1 à l'intérieur de l'alésage cylindrique 3, dans l'exemple représenté, au moyen de rivets 12. Bien entendu, cette fixation peut être réalisée par tout autre moyen.Each blade 4 and its counter blade 5 are fixed on knuckle 1 inside the cylindrical bore 3, in the example shown, by means of rivets 12. Of course, this fixing can be carried out by any other means.

Le charnon mobile 2 fixé sur la porte P est monté à l'extrémité supérieure de l'axe d'articulation 6 (fig. 1 et 2) et est rendu solidaire dudit axe de façon que l'ouverture et la fermeture de la porte entraíne le pivotement dudit axe 6.The movable knuckle 2 fixed on the door P is mounted at the upper end of the hinge pin 6 (fig. 1 and 2) and is made integral with said axis so that the opening and the closing the door causes said axis 6 to pivot.

Le fonctionnement de la charnière est le suivant :The operation of the hinge is as follows:

Lorsque l'on ouvre la porte, le charnon mobile 2 entraíne l'axe d'articulation 6 en rotation. La rotation de l'axe 6 amène le bossage 11 de sa partie centrale contre la partie incurvée 4a de chacune des lames élastiques 4, cette partie 4a s'insérant entre deux bossages. Pour ce faire, les bossages 11 doivent soulever l'extrémité 4a de la lame élastique 4 et sa contre lame 5, ce qui génère un couple de manoeuvre au niveau de la porte P du véhicule. When we open the door, the mobile knuckle 2 drives the axis of articulation 6 in rotation. The rotation of axis 6 brings the boss 11 of its central part against the curved part 4a of each of the elastic blades 4, this part 4a fitting between two bosses. To do this, the bosses 11 must lift the end 4a of the elastic blade 4 and its counter blade 5, which generates a torque level of door P of the vehicle.

Sur les figures 7 à 9, on a représenté en coupe l'axe d'articulation 6a, avec les lames élastiques 4 montées dans l'alésage 3 du charnon fixe 1 dans trois positions différentes. Comme on peut le voir sur ces figures, les bossages 11 de l'axe 6a sont disposés par groupe de deux afin d'obtenir deux points 11a et 11b de maintien sur la course de rotation de la porte, la variation du nombre de bossages 11 par groupe permettant de faire varier le nombre de points de maintien de la porte. Sur les figures, on a représenté l'axe 6a dans la position porte ouverte (fig.7) porte ouverte en position parking (fig.8) et porte fermée (fig. 9).
Bien entendu, le nombre de bossages et de lames élastiques peut être moindre ou plus élevé pour obtenir des efforts de manoeuvre différents.In Figures 7 to 9, there is shown in section the hinge axis 6a, with the elastic blades 4 mounted in the bore 3 of the fixed knuckle 1 in three different positions. As can be seen in these figures, the bosses 11 of the axis 6a are arranged in groups of two in order to obtain two points 11a and 11b for holding on the door rotation stroke, the variation in the number of bosses 11 per group allowing the number of door holding points to be varied. In the figures, the axis 6a has been shown in the open door position (fig. 7) open door in parking position (fig. 8) and closed door (fig. 9).
Of course, the number of bosses and elastic blades can be lower or higher to obtain different operating forces.

De même, les angles sont donnés à titre d'exemples et ne sont pas limitatifs.
La butée pleine ouverture est assurée par une patte 22 du charnon mobile 2 qui vient au contact avec une portée 23 du charnon fixe 1 comme représenté sur la figure 10 qui montre, en plan, la charnière selon l'intervention, la porte du véhicule ouverte au maximum.Likewise, the angles are given by way of examples and are not limiting.
The full opening stop is provided by a tab 22 of the movable knuckle 2 which comes into contact with a bearing surface 23 of the fixed knuckle 1 as shown in FIG. 10 which shows, in plan, the hinge according to the intervention, the vehicle door open to the maximum.

Une variante de réalisation de la charnière à arrêt de porte intégré va maintenant être décrite. Cette réalisation a pour objet d'obtenir un couple encore plus important lors de la manoeuvre de la porte du véhicule, ce qui peut être recherché pour des portes plus lourdes.An alternative embodiment of the stop hinge integrated door will now be described. This achievement has the object of obtaining an even greater torque during maneuvering the vehicle door, which can be sought after for heavier doors.

Dans cette réalisation, l'extrémité 4a de chaque lame élastique repose sur un profilé en élastomère fixé longitudinalement à l'intérieur de l'alésage 3 du charnon 1. Ces profilés jouent un rôle d'amortisseur.
Lorsque l'axe 6 du charnon pivote, l'extrémité recoubée 4a de chaque lame 4 est maintenue fermement au contact de la partie 6a et du passage des bossages 11, ladite extrémité comprime le profilé en élastomère et se loge entre deux bossages et s'y maintient fermement. In this embodiment, the end 4a of each elastic blade rests on an elastomer profile fixed longitudinally inside the bore 3 of the knuckle 1. These profiles play a damping role.
When the axis 6 of the knuckle pivots, the bent end 4a of each blade 4 is held firmly in contact with the part 6a and the passage of the bosses 11, said end compresses the elastomer profile and is housed between two bosses and s' holds it firmly.

En se reportant à la figure 11, on retrouve en coupe le charnon fixe 1 comportant un alésage cylindrique 3, un axe d'articulation 6 comportant des bossages 11 dans sa partie centrale 6a. Entre l'alésage 3 du charnon fixe 1 et l'axe d'articulation 6a, sont insérées trois lames flexibles 4 qui coopèrent avec les bossages 11 de l'axe d'articulation par leurs extrémités recourbées 4a. Chaque extrémité 4a repose sur un profilé 13 en élastomère. Ce profilé 13 peut être collé à l'intérieur de l'alésage 3 du charnon 1, ou disposé dans une rainure, et s'étend sur la longueur de la lame élastique 4.
L'un des côtés du profilé 13 a une configuration adéquate lui permettant d'épouser l'extrémité 4a de la lame élastique.Referring to Figure 11, there is in section the fixed knuckle 1 having a cylindrical bore 3, a hinge pin 6 having bosses 11 in its central part 6a. Between the bore 3 of the fixed knuckle 1 and the hinge pin 6a, three flexible blades 4 are inserted which cooperate with the bosses 11 of the hinge pin by their curved ends 4a. Each end 4a rests on an elastomer profile 13. This profile 13 can be glued to the interior of the bore 3 of the knuckle 1, or disposed in a groove, and extends over the length of the elastic blade 4.
One of the sides of the profile 13 has an adequate configuration allowing it to match the end 4a of the elastic blade.

Sur les figures 13 à 15, on a représenté en coupe l'axe d'articulation 6a de la charnière selon l'invention avec les lames élastiques 4 montées dans l'alésage 3 du charnon fixe 1, avec leurs profilés en élastomères 13, dans trois positions différentes:

  • porte fermée (figure 13)
  • porte ouverte position parking (figure 14) et porte ouverte dite « ouverture maximum » (figure 15).
In Figures 13 to 15, there is shown in section the hinge axis 6a of the hinge according to the invention with the elastic blades 4 mounted in the bore 3 of the fixed knuckle 1, with their elastomer profiles 13, in three different positions:
  • door closed (figure 13)
  • door open in parking position (Figure 14) and door open called "maximum opening" (Figure 15).

Selon l'invention pour obtenir lors de l'ouverture de la porte des couples différents, plus faibles ou plus importants, on peut également disposer un profilé élastomère dans la première réalisation décrite, comportant une contre lame afin d'avoir une élasticité différente de l'extrémité 4a de la lame élastique 4.According to the invention to obtain when opening the carries different, weaker or more couples important, we can also have a profile elastomer in the first embodiment described, having a counter blade in order to have an elasticity different from the end 4a of the elastic blade 4.

Bien entendu, la présente invention peut s'appliquer à tout autre ouvrant dont on désire obtenir plusieurs points d'ouverture.Of course, the present invention can be applied to any other opening of which we wish to obtain several points opening hours.
