Description

La présente invention concerne un système destiné à marquer la position relative d'un élément mobile par rapport à un élément fixe, l'élément mobile pouvant occuper deux positions extrêmes, proche ou éloignée, par rapport à l'élément fixe.The present invention relates to a system intended to mark the relative position of a movable element with respect to a fixed element, the movable element being able to occupy two extreme positions, close or distant, with respect to the fixed element.

Le terme élément mobile englobe par exemple les vantaux, portes, battants, grilles, etc. susceptibles d'être déplacés de façon autonome ou non, par un mouvement quelconque, par rapport à un élément fixe, tel qu'une structure, ossature, montant, charpente, etc.The term mobile element includes, for example, leaves, doors, leaves, grilles, etc. capable of being moved independently or not, by any movement, relative to a fixed element, such as a structure, framework, upright, frame, etc.

Par exemple, dans le cas des véhicules, l'élément mobile est défini par la porte, tandis que l'élément fixe est défini par le montant de la caisse du véhicule.For example, in the case of vehicles, the movable element is defined by the door, while the fixed element is defined by the amount of the vehicle body.

Les systèmes destinés à marquer la position relà- tive de la porte par rapport au montant d'un véhicule comportent généralement un levier, articulé par l'une de ses extrémités sur l'élément fixe ou montant de la caisse, et des moyens de guidage, disposés sur l'élément mobile ou porte lesquels coopèrent avec ledit levier, dont l'autre extrémité est située dans le volume interne de la porte. Au moins une charnière assure le mouvement en rotation, autour de l'axe vertical de la charnière,de la porte par rapport au montant. Ces moyens de guidage sont actusllement constitués d'un galet porté par une chape, et maintenu contre un profil ondulatoire, ménagé sur un des bords latéraux du levier, par un ressort. Sur l'autre bord latéral, sont appliqués des organes élastiques qui s'opposent à l'action du ressort de manière à guider et maintenir le levier contre le galet. L'élément mobile, tel que la porte, est ainsi maintenu dans une position souhaitée par rapport à l'élément fixe, tel que le montant du véhicule, au moyen du galet qui immobilise la porte lorsqu'il se trouve dans un des creux du profil ondulatoire.The systems intended to mark the relative position of the door relative to the upright of a vehicle generally comprise a lever, articulated by one of its ends on the fixed element or upright of the body, and guide means , arranged on the movable element or door which cooperate with said lever, the other end of which is located in the internal volume of the door. At least one hinge ensures the rotational movement, around the vertical axis of the hinge, of the door relative to the upright. These guide means are actusllement consisting of a roller carried by a yoke, and held against a wave profile, formed on one of the side edges of the lever, by a spring. On the other lateral edge, elastic members are applied which oppose the action of the spring so as to guide and hold the lever against the roller. The movable element, such as the door, is thus maintained in a desired position relative to the fixed element, such as the amount of the vehicle, by means of the roller which immobilizes the door when it is in one of the hollows of the wave profile.

Les systèmes comportant ces moyens de guidage donnent des résultats convenables. Cependant, leur fia- bilité est parfois mise en cause, de par les ouvertures et/ou fermetures répétées qui amplifient les divers jeux fonctionnels entre les pièces. Ainsi; certaines d'entre elles, et notamment les moyens de gui-' dage, risquent d'être détériorées entraînant des difficultés et même l'impossibilité, d'ouvrir et/ou de fermer la porte ou de maintenir celle-ci dans une position intermédiaire.The systems comprising these guiding means give suitable results. However, their reli- b i l ity is sometimes questioned, because of the heart are opened and / or repeated closures that amplify the various functional clearances between parts. So; some of them, including the means of guineas' d ge, easily damaged causing difficulty and even the impossibility, to open and / or close the door or keep it in a intermediate position.

De plus, ces systèmes nécessitent de fréquents graissages, lesquels ne sont pas'toujours effectués, entraînant des grippages de fonctionnement entre les pièces et l'apparition de bruits désagréables.In addition, these systems require frequent lubrication, which is not always done, resulting in operating seizures between the parts and the appearance of unpleasant noise.

La présente invention a pour but de pallier ces inconvénients et propose un système destiné à marquer la position relative d'un élément mobile par rapport à un élément fixe d'une fiabilité accrue, d'entretien réduit, de fonctionnement silencieux et insensible aux variations extérieures de température.The present invention aims to overcome these drawbacks and proposes a system intended to mark the relative position of a mobile element with respect to a fixed element of increased reliability, reduced maintenance, silent operation and insensitive to external variations. of temperature.

A cet effet,- selon l'invention, le système destiné à marquer la position relative d'un élément mobile par rapport à un élément fixe, ledit élément mobile pouvant occuper deux positions extrêmes, proche ou éloignée, du type comportant un levier articulé par l'une de ses extrémités sur ledit élément fixe et des moyens de guidage disposés sur ledit élément mobile et coopérant avec ledit levier, lesdits moyens de guidage étant au voisinage de l'articulation dudit levier dans la position extrême proche et étant en butée contre l'autre extrémité dudit levier. dans la position extrême éloignée, est remarquable en ce que lesdits moyens de guidage sont constitués par des galets montés rotatifs.et solidaires dudit élément mobile, lesdits galets étant disposés de part et d'autre dudit levier en le pressant entre eux, un profil ondulatoire ménagé sur ledit levier étant susceptible de coopérer avec au moins l'un desdits galets, de façon à immobiliser ledit élément mobile dans une position relative-souhaitée, lorsque ledit galet se trouve dans un des creux dudit profil. Avantageusement, deux profils ondulatoires sont ménagés respectivement de part et d'autre dudit levier et sont symétriques l'un de l'autre par rapport à un plan médian dudit levier, chaque galet coopérant avec un desdits profils. Ainsi, les efforts exercés par lesdits galets, déformables élastiquement, sur les profils sont de sens opposés., l'un vers l'autre, ce qui procure un maintien efficace du levier dans chaque position souhaitée définie par les creux des profils. Lesdits galets sont par exemple, en matière plastique synthétique ce qui réduit l'entretien du système et augmente le silence du fonctionnement. Préférentiellement, l'extrémité dudit levier, marquant la position extrême éloignée dudit élément mobile par rapport audit élément fixe, est terminée de façon coudée, au moins un desdits galets venant en butée contre cet te extrémité. Dans un mode préféré de réalisation, lesdits galets comportant, chacun, deux flancs entre lesquels est ménagée une gorge coopérant avec chaque profil ondulatoire, lesdites gorges formant ainsi un guide pour ledit levier. Chaque galet est monté sur une barre de flexion disposée dans un boîtier-solidaire dudit élément mobile.To this end, - according to the invention, the system intended to mark the relative position of a movable element with respect to a fixed element, said movable element being able to occupy two extreme positions, close or distant, of the type comprising a lever articulated by one of its ends on said fixed element and guide means arranged on said movable element and cooperating with said lever, said guide means being in the vicinity of the articulation of said lever in the extreme near position and being in abutment against the 'other end of said lever. in the extreme remote position, is remarkable in that said guide means are constituted by rollers mounted ro t a tifs.et integral with said movable element, said rollers being arranged on either side of said lever by pressing it between them, a wave profile formed on said lever being capable of cooperating with at least one of said rollers, so as to immobilize said movable element in a relative-desired position, when said roller is in one of the hollows of said profile. Advantageously, two wave profiles are formed respectively on either side of said lever and are symmetrical to each other with respect to a median plane of said lever, each roller cooperating with one of said profiles. Thus, the forces exerted by said elastically deformable rollers on the profiles are in opposite directions, towards each other, which provides effective maintenance of the lever in each desired position defined by the hollows of the profiles. Said rollers are for example made of synthetic plastic which reduces the maintenance of the system and increases the silence of the operation. Preferably, the end of said lever, marking the extreme position remote from said movable element with respect to said fixed element, is terminated at an angle, at least one of said rollers abutting against this end. In a preferred embodiment, said rollers each having two sides between which is formed a groove cooperating with each wave profile, said grooves thus forming a guide for said lever. Each roller is mounted on a bending bar arranged in a housing integral with said movable element.

Avantageusement, les extrémités des barres de flexion peuvent être entourées respectivement d'un support en élastomère agencé dans le boîtier, autorisant ainsi un jeu fonctionnel de chaque barre par rapport au boîtier. Une bague, en matériau synthétique, peut également être interposée entre chacun des galets et des barres de flexion augmentant alors le silence de fonctionnement du système.Advantageously, the ends of the bending bars can be respectively surrounded by an elastomer support arranged in the housing, thus allowing a functional clearance of each bar relative to the housing. A ring, made of synthetic material, can also be interposed between each of the rollers and bars flexion increasing the operating silence of the system.

Le système selon l'invention montré par ces figures, est destiné à marquer la position relative d'un élément mobile, tel qu'une porte de véhicule 1, par rapport à un élément fixe, tel qu'un montant de caisse 2 de cedit véhicule.The system according to the invention shown in these figures is intended to mark the relative position of a movable element, such as a vehicle door 1, with respect to a fixed element, such as a body pillar 2 of cedit vehicle.

La porte 1 et le montant 2 sont articulés autour d'un axe vertical 3 d'une charnière 4. La rotation de la porte 1 s'effectue autour de cet axe 3.The door 1 and the upright 2 are articulated around a vertical axis 3 of a hinge 4. The rotation of the door 1 takes place around this axis 3.

Il va de soi que, pour d'autres applications, le mouvement pourrait être différent de celui présenté dans cet exemrle.It goes without saying that, for other applications, the movement could be different from that presented in this example.

Le système comporte d'une part, un levier articulé par l'une de ses extrémités 6. autour d'un axe de rotation 7, monté sur des pattes 8 solidaires du montant 2 du véhicule et d'autre part, des moyens de guidage 12 disposés sur la porte 1 et coopérant avec le levierThe system comprises on the one hand, a lever articulated by one of its ends 6. around an axis of rotation 7, mounted on lugs 8 integral with the amount 2 of the vehicle and on the other hand, guide means 12 arranged on door 1 and cooperating with the lever

Plus précisément, le levier 5 comporte, avantageusement, deux profils ondulatoires 14 et 15 ménagés res- pectivement sur chacun des bords latéraux 16 et 17 du levier. Les profils 14 et 15 sont symétriques par rapport à un plan médian P du levier 5 et définissent res- pectivement des creux 14-1, 15-1 et des bosses 14-2, 15-2. L'extrémité 18 du levier 5, opposée à celle articulée autour de l'axe de rotation 7, est terminée de façon coudée, en définissant ainsi une butée 20.More specifically, the lever 5 advantageously comprises two wave profiles 14 and 15 formed res- pec tively on each of the lateral edges 16 and 17 of the lever. The profiles 14 and 15 are symmetrical with respect to a median plane P of the lever 5 and define res- p ec tively hollow 14-1, 15-1 and 14-2 bumps 15-2. The end 18 of the lever 5, opposite to that articulated around the axis of rotation 7, is terminated at an angle, thus defining a stop 20.

La majeure partie du levier 5, à l'exception de l'extrémité 6, est agencée dans le volume interne 21 de la porte 1, laquelle comporte une ouverture 22 permettant la mise en place et le mouvement dudit levier.Most of the lever 5, with the exception of the end 6, is arranged in the internal volume 21 of the door 1, which has an opening 22 allowing the positioning and movement of said lever.

Les moyens de guidage 12, selon l'invention sont constitués avantageusement par deux galets 23, 24, montés rotatifs, portés chacun par un arbre ou une barre de flexion 26, 27 agencé dans un boîtier 29. Ce dernier est solidaire de la porte 1 par l'intermédiaire de vis 30 représentées sur les figures 3-à 6, et comporte également une ouverture 32 disposée en regard de l'ouverture 22.The guide means 12 according to the invention advantageously consist of two rollers 23, 24, mounted to rotate, each carried by a shaft or a bending bar 26, 27 arranged in a housing 29. The latter is integral with the door 1 by means of screws 30 shown in FIGS. 3 to 6, and also comprises an opening 32 arranged opposite the opening 22.

Les extrémités 33, 34 de la barre de flexion 26 portant le galet 23 et les extrémités 35, 36 de la barre de flexion 27 portant le galet 24, sont emprisonnées par une cage 38 dans.des fentes 39 pratiquées dans les parois du boîtier 29 servant d'appui aux extrémités des barres 26 et 27. La cage 38 est solidaire du boîtier 29 au moyen, par exemple, de points de soudure 40 et est munie également d'une ouverture 41 disposée en regard des ouvertures 22 et 32, précédentes.'The ends 33, 34 of the bending bar 26 carrying the roller 23 and the ends 35, 36 of the bending bar 27 carrying the roller 24, are trapped by a cage 38 in. Slots 39 formed in the walls of the housing 29 serving as support for the ends of the bars 26 and 27. The cage 38 is secured to the housing 29 by means, for example, of welding points 40 and is also provided with an opening 41 disposed opposite the openings 22 and 32, previous . '

Les galets 23 et 24 comportent chacun, deux flancs latéraux 43 et 44 entre lesquels est ménagée une gorge 45 coopérant avec chaque profil ondulatoire 14 et 15. Chaque gorge 45, entourée de ses flancs 43 et 44, forme un guide pour le levier 5.et exerce une pression sur les bords latéraux 16 et 17 et par conséquent, les profils ondulatoires 14 et 15. Les efforts exercés par les galets, sont avantageusement en opposition l'un de l'autre, grâce à la disposition symétrique des profils 14 et 15. Le levier est ainsi maintenu dans un plan défini par l'articulation 6 et les galets 23 et 24.The rollers 23 and 24 each have two lateral flanks 43 and 44 between which is formed a groove 45 cooperating with each wave profile 14 and 15. Each groove 45, surrounded by its flanks 43 and 44, forms a guide for the lever 5. and exerts a pressure on the lateral edges 16 and 17 and consequently, the wave profiles 14 and 15. The forces exerted by the rollers, are advantageously in opposition to each other, thanks to the symmetrical arrangement of the profiles 14 and 15. The lever is thus maintained in a plane defined by the articulation 6 and the rollers 23 and 24.

Dans un mode préféré de réalisation, les galets sont en matière plastique résineuse synthétique ou analogue, présentant de bonnes caractéristiques d'élasticité en procurant un entretien rdduit et un silence de fonctionnement accru.In a preferred embodiment, the rollers are made of synthetic resinous plastic or the like, exhibiting good elasticity characteristics by providing reduced maintenance and increased operating silence.

Le fonctionnement du système sera décrit en regard des figures 1 et 2.The operation of the system will be described with reference to Figures 1 and 2.

Plus précisément, la figure 1 illustre la porte 1 d'un véhicule dans une position extrême fermée, les moyens de guidage 12 étant dans leur position la plus proche de l'axe d'articulation 7 du levier 5. Les gorges 45 des galets 23 et 24 sont en contact des bords latéraux 16 et 17 du levier 5, mais en dehors des profils ondulatoires 14 et 15.More specifically, Figure 1 illustrates the door 1 of a vehicle in an extreme closed position, the guide means 12 being in their position closest to the hinge axis 7 of the lever 5. The grooves 45 of the rollers 23 and 24 are in contact with the lateral edges 16 and 17 of the lever 5, but outside the wave profiles 14 and 15.

Lorsque l'on désire ouvrir la porte pour que celle-ci soit maintenue par exemple dans l'autre position extrême ouverte illustrée par la figure 2, on agit sur une poignée (non visible sur les figures) solidaire de la porte 1, laquelle pivote autour de l'axe d'articulation 3 de la charnière 4 par rapport au montant 7 de la caisse du véhicule. Les galets 23 et 24, solidaires de la porte par l'intermëdiaire des barres de flexion 26 et 27 montées sur le boîtier 29, roulent sur les profils ondulatoires 14 et 15 passant successivement sur les creux 14-1, 15-1 et bosses 14-2, 15-2 en se déformant élastiquement. Le levier 5, guidé par les gorges 45 et les flancs 43, 44 des galets, pivote autour de l'axe de l'axe 7 d'articulation par rapport au montant 2. La position extrême ouverte est atteinte lorsque l'un des galets, en l'occurrence le galet 23, est contre la butée 20 de l'extrémité coudée 18 du levier 5. Dans une autre réalisation, on pourrait également prévoir une butée à l'encontre du galet 24.When one wishes to open the door so that it is maintained for example in the other extreme open position illustrated in FIG. 2, one acts on a handle (not visible in the figures) integral with the door 1, which pivots around the hinge axis 3 of the hinge 4 relative to the amount 7 of the vehicle body. The rollers 23 and 24, integral with the door by means of the bending bars 26 and 27 mounted on the housing 29, roll on the wave profiles 14 and 15 passing successively on the recesses 14-1, 15-1 and bumps 14 -2, 15-2 by deforming elastically. The lever 5, guided by the grooves 45 and the flanks 43, 44 of the rollers, pivots about the axis of the axis 7 of articulation relative to the upright 2. The extreme open position is reached when one of the rollers , in this case the roller 23, is against the stop 20 of the bent end 18 of the lever 5. In a another embodiment, one could also provide a stop against the roller 24 .

Dans cette configuration, les galets 23 et 24 sont dans des creux 14-1 et 15-1 et immobilisent ainsi en position la porte 1 par rapport au montant 2.In this configuration, the rollers 23 and 24 are in recesses 14-1 and 15-1 and thus immobilize the door 1 in position relative to the upright 2.

Une pluralité de positions intermédiaires de la porte 1 par rapport au montant 2 peuvent également être obtenues. Le nombre de creux agencés sur les profils définit le nombre de positions que la porte peut occuper. L'arrêt et le maintien dans une quelconque position'de la porte s'effectuent sans difficulté, les gorges des galets sont toujours en contact avec les profils ondulatoires, grâce à la déformation élastique de celles-ci sur le passage des bosses, lesdites gorges revenant dans leur position initiale lorsqu'elles sont en contact avec les creux.A plurality of intermediate positions of the door 1 relative to the upright 2 can also be obtained. The number of recesses arranged on the profiles defines the number of positions that the door can occupy. Stopping and maintaining in any position'de the door is carried out without difficulty, the grooves of the rollers are always in contact with the wave profiles, thanks to the elastic deformation of these on the passage of the bumps, said grooves returning to their initial position when they are in contact with the recesses.

Lé fonctionnement du système selon l'invention, s'effectue de façon silencieuse grâce à la matière desdits galets sans pour cela nécessiter un quelconque entretien.The operation of the system according to the invention is carried out silently thanks to the material of said rollers without requiring any maintenance.

Les figures 5 et 6 représentent deux vues d'une variante de réalisation du système selon l'invention augmentant notamment le silence de fonctionnement.Figures 5 and 6 show two views of an alternative embodiment of the system according to the invention notably increasing the operating silence.

Pour cela, les extrémités 33 et 34 de la barre de flexion .26 et les extrémités 35 et 36 de la barre de flexion 27 sont entourëes d'une douille 50 adhérisée dans un support 51, de préférence en élastomère. Ces supports 51 sont maintenus et emprisonnés dans le boîtier 29 par la cage 38 de forme simplifiée, mais de fonction identique. La cage est solidaire du boîtier 29 par l'intermédiaire de languettes métalliques 53 prévues sur le boîtier, et rabattues contre la cage. Cette variante de réalisation assure notamment une liberté de mouvement des deux barres 26, 27, par rapport à leur axe respectif, lors du fonctionnement du système. Les barres sont ainsi montées flottantes dans les supports 51.For this, the ends 33 and 34 of the bending bar .26 and the ends 35 and 36 of the bending bar 27 are surrounded by a sleeve 50 adhered in a support 51, preferably made of elastomer. These supports 51 are held and trapped in the housing 29 by the cage 38 of simplified form, but of identical function. The cage is secured to the housing 29 by means of metal tabs 53 provided on the housing, and folded against the cage. This variant embodiment notably provides freedom of movement of the two bars 26, 27, relative to their respective axis, during the operation of the system. The bars are thus mounted floating in the supports 51.

Avantageusement, une bague 54, de préférence en matériau synthétique du type plastique, est interposée entre les galets 23, 24 et les barres 26, 27, ce qui améliore le silence de fonctionnement du système.Advantageously, a ring 54, preferably made of synthetic material of the plastic type, is interposed between the rollers 23, 24 and the bars 26, 27, which improves the operating silence of the system.

Le système décrit ci-dessus comporte donc des avantages déterminants par rapport aux systèmes de l'art antérieur, notamment grâce aux moyens de guidage et de maintien vis-à-vis du levier et des efforts symétriques exercés par les galets montés en opposition à l'encontre du levier. De plus, l'entretien du système est quasiment nul, la longévité et le silence de fonc- tionnement du système sont accrus. De même, les variations de températures extérieures pour lesquelles le système est soumis, n'influent pas sur le fonctionnement de-celui-ci.The system described above therefore has decisive advantages over the systems of the prior art, in particular thanks to the means for guiding and holding vis-à-vis the lever and the symmetrical forces exerted by the rollers mounted in opposition to the against the lever. In addition, system maintenance is almost zero, longevity and silence func- ti onment of the system are increased. Likewise, the variations in outside temperatures for which the system is subjected, do not influence the operation thereof.
