Description

La présente invention concerne une butée anti-vibratoire pour ouvrant, notamment un ouvrant de véhicule.The present invention relates to an anti-vibration abutment for opening, in particular a vehicle opening.

Les ouvrants de véhicules (portes des passagers ou hayon) sont articulés sur des charnières et se bloquent en position fermée sur une ouverture du châssis par un dispositif de verrouillage. Une fois qu'ils sont fermés et que le véhicule roule, les petits jeux existants au niveau des charnières et/ou du dispositif de verrouillage entraîne des vibrations de l'ouvrant ; ces vibrations sont bruyantes et désagréables et elles peuvent entraîner à terme une détérioration de l'ouvrant. Aussi est-il connu, par exemple par le document US 5421124, d'empêcher ces vibrations en implantant un moyen de contrainte entre l'ouvrant et le châssis sur lequel il porte en position fermée.The opening of vehicles (passenger doors or tailgate) are articulated on hinges and lock in a closed position on an opening of the frame by a locking device. Once they are closed and the vehicle rolls, the existing small games at the hinges and / or the locking device causes vibration of the opening; these vibrations are noisy and unpleasant and can eventually lead to deterioration of the opening. It is known, for example from the document US 5421124, to prevent these vibrations by implanting a means of stress between the opening and the frame on which it carries in the closed position.

Il est notamment connu d'implanter des butées compressibles, soit réglables soit fixes ; les premières sont généralement trop encombrantes et les secondes ne donnent pas entièrement satisfaction en raison d'une trop forte montée en effort sous la compression de la butée.It is in particular known to implement compressible stops, either adjustable or fixed; the former are generally too cumbersome and the seconds are not entirely satisfactory because of an excessive increase in effort under the compression of the stop.

Le document DE 19 855 700 décrit un butée pour meubles composée d'une partie faiblement déformable en caoutchouc logée dans une douille indéformable. La partie déformable dépasse de la douille en formant un chapeau conique aplati et peut être partiellement évidée. Une telle butée à faible course n'est pas adaptée pour les ouvrants d'automobiles.Document DE 19 855 700 describes a furniture stop composed of a weakly deformable rubber part housed in a deformable sleeve. The deformable portion protrudes from the socket forming a flat tapered cap and may be partially recessed. Such a short stroke stop is not suitable for opening of automobiles.

Le document FR 2 703 395 décrit une butée pour ouvrant d'automobile dans laquelle l'effort résistant n'est pas créé par le caoutchouc de la butée mais par l'amortissement pneumatique créé par l'air enfermé dans la butée et s'échappant de manière contrôlée par un orifice.The document FR 2 703 395 describes an abutment for an automobile opening in which the resistant force is not created by the rubber of the abutment but by the pneumatic damping created by the air enclosed in the abutment and escaping in a controlled manner by an orifice.

Le but de l'invention est de proposer une butée compressible ne présentant pas cet inconvénient.The object of the invention is to provide a compressible stop that does not have this disadvantage.

L'invention atteint son but grâce à une butée compressible conforme à la revendication 1 annexée.The invention achieves its object by means of a compressible abutment according to the appended claim 1.

Avantageusement, les deux troncs de cônes comportent des reliefs intérieurs, par exemple des nervures, se correspondant, de manière à empêcher les surfaces intérieures des troncs de cône de se coller l'une sur l'autre au terme de la compression du dispositif.Advantageously, the two truncated cones comprise internal reliefs, for example ribs, corresponding to prevent the inner surfaces of the truncated cones from sticking to one another after the compression of the device.

Avantageusement, une courte zone de raccordement cylindrique sépare les deux troncs de cône au niveau de leur union, de façon à ménager la place suffisante pour leur compression.Advantageously, a short cylindrical connecting zone separates the two truncated cones at their union, so as to provide sufficient space for their compression.

Bien qu'on décrive la forme de la partie déformable de la butée comme étant constituée de deux troncs de cône accolés par leur grande la forme pourra s'en écarter, par exemple en s'arrondissant, de manière à former deux cuvettes opposées constituant éventuellement une sphère creuse, du moment que cette forme est compatible avec la condition que l'effort résistant soit sensiblement constant sur une plage de déformation importante.Although the shape of the deformable part of the abutment is described as consisting of two truncated cones joined by their large the shape may deviate from it, for example by turning round, so as to form two opposite cups possibly constituting a hollow sphere, as long as this shape is compatible with the condition that the resisting force is substantially constant over a range of significant deformation.

L'invention sera mieux comprise et d'autres avantages et caractéristiques seront mis en évidence à la lecture de la description suivante, se référant aux dessins annexés sur lesquels :

  • la figure 1 est une vue en perspective de dessus d'une butée conforme à l'invention,
  • la figure 2 est une vue en perspective de dessous de la même butée,
  • la figure 3 est une vue en coupe longitudinale et en perspective de la même butée,
  • la figure 4 représente la loi d'effort en fonction de la déformation de la butée conforme à l'invention.
The invention will be better understood and other advantages and characteristics will be highlighted on reading the following description, with reference to the appended drawings in which:
  • FIG. 1 is a perspective view from above of an abutment according to the invention,
  • FIG. 2 is a perspective view from below of the same abutment,
  • FIG. 3 is a view in longitudinal section and in perspective of the same abutment,
  • FIG. 4 represents the force law as a function of the deformation of the abutment according to the invention.

La butée 1, réalisée intégralement en caoutchouc ou en élastomère, est formée d'une base 2 de fixation et d'une partie déformable 3 biconique creuse. La base 2 comprend une zone cylindrique 4 surmontée par une zone tronconique 5 la reliant à la partie déformable 3. Sous la zone cylindrique 4 est prévu un téton annulaire central 6 à quatre fentes 7, comportant une entrée conique 8. A cheval sur les zones cylindrique 4 et tronconique 5 sont pratiquées des ouvertures transversales parallèles 9 d'allégement.The abutment 1, made entirely of rubber or elastomer, is formed of a fixing base 2 and a hollow biconic deformable part 3. The base 2 comprises a cylindrical zone 4 surmounted by a frustoconical zone 5 connecting it to the deformable part 3. Under the cylindrical zone 4 is provided a central annular stud 6 with four slots 7, having a conical inlet 8. Straddling the zones cylindrical 4 and frustoconical 5 are formed parallel transverse openings 9 lightening.

La partie déformable 3 biconique comprend deux troncs de cônes creux 10, 11- unis par leur grande base commune marquée par une courte zone cylindrique de raccordement 16. La petite base du tronc de cône supérieur 11 est percée d'une ouverture 12, permettant d'introduire un outil pour la fixation de la base 2 au moyen d'une vis ou analogue sur l'ouvrant ou sur le châssis ; l'intérieur de la partie déformable 3 est creux et la base 2 comporte elle-même un insert central 13 permettant de déverrouiller le téton de fixation 6.The biconical deformable portion 3 comprises two truncated hollow cones 10, 11- united by their large common base marked by a short cylindrical connecting zone 16. The small base of the upper conical truncum 11 is pierced with an opening 12, allowing introducing a tool for fixing the base 2 by means of a screw or the like on the opening or on the frame; the inside of the deformable portion 3 is hollow and the base 2 itself comprises a central insert 13 for unlocking the fixing pin 6.

La surface intérieure des troncs de cône 10, 11 comporte des nervures 14, 15 disposée par exemple selon deux plans diamétraux perpendiculaires. Les nervures inférieures 14 sont arrondies à leur extrémité supérieure et les nervures supérieures 15 sont arrondies à leur extrémité inférieure, de manière qu'elles permettent la compression des deux troncs de cône l'un vers l'autre lors de l'écrasement de la zone déformable, jusqu'à un point maximum où les nervures supérieures 15 touchent les nervures inférieures 14 et s'appuient contre elles. Si l'effort de compression cesse (quand l'ouvrant est ouvert), l'élasticité de la butée permet son retour en position non déformée, le risque de collage des surfaces intérieures des troncs de cône étant écarté grâce au nervures 14, 15.The inner surface of the truncated cones 10, 11 comprises ribs 14, 15 arranged for example in two perpendicular diametrical planes. The lower ribs 14 are rounded at their upper end and the upper ribs 15 are rounded at their lower end, so that they allow compression of the two trunks of cone towards each other during the crushing of the deformable zone, to a maximum point where the upper ribs 15 touch the lower ribs 14 and bear against them. If the compressive force ceases (when the opening is open), the elasticity of the abutment allows its return to the undeformed position, the risk of bonding the inner surfaces of the truncated cones being removed thanks to the ribs 14, 15.

La figure 4 montre la courbe caractéristique de l'effort de compression (en ordonnée) en fonction de la déformation (en abscisse). On y voit que la courbe présente après une première montée A, un plateau B correspondant à la déformation des deux troncs de cône l'un sur l'autre, suivi par une nouvelle montée C une fois que les cônes sont écrasés et portent l'un sur l'autre par l'intermédiaire des nervures.Figure 4 shows the characteristic curve of the compressive force (in ordinate) as a function of the deformation (in abscissa). It shows that the curve presents after a first climb A, a plateau B corresponding to the deformation of the two cone frustums one on the other, followed by a new rise C once the cones are crushed and carry the one on the other through the ribs.
