Abstract

The compressible anti-vibration stop (1) is made from rubber or an elastomer material and consists of a fixing base (2) and a hollow axially deformable section (3) in the shape of two truncated cones (10, 11) joined by their larger ends and producing a constant resistance over a wide range of deformation. The two cones are joined by a short cylindrical section (16) and have inner ribs (14, 15) which coincide and prevent the inner surfaces of the cones from sticking together when compressed.

Description

La présente invention concerne une butée anti-vibratoire pour ouvrant, notamment un ouvrant de véhicule.The present invention relates to an anti-vibration stop 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 entraíne des vibrations de l'ouvrant ; ces vibrations sont bruyantes et désagréables et elles peuvent entraíner 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 openings of vehicles (passenger doors or tailgate) are articulated on hinges and lock in the closed position on a opening of the chassis by a locking device. Once they are closed and the vehicle is running, the small clearances existing in the hinges and / or the locking device causes vibrations of opening it; these vibrations are noisy and unpleasant and they can eventually cause deterioration of the opening. So he is known, by example by document US 5421124, to prevent these vibrations by implanting a means of constraint between the opening and the frame on which it door in 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 notably known to install compressible stops, ie adjustable or fixed; the former are generally too bulky and the seconds are not entirely satisfactory due to too much strong rise in force under the compression of the stop.

Le but de l'invention est de proposer une butée compressible ne présentant pas cet inconvénient.The object of the invention is to propose a compressible stop not not having this drawback.

L'invention atteint son but grâce à une butée compressible comprenant une base de fixation et une partie déformable axialement, caractérisée en ce que la partie déformable est creuse et constituée de deux troncs de cônes creux unis par leur grande base, moyennant quoi l'effort résistant est sensiblement constant sur une plage de déformation importante.The invention achieves its goal thanks to a compressible stop comprising a fixing base and an axially deformable part, characterized in that the deformable part is hollow and made up of two trunks of hollow cones united by their large base, whereby the effort resistance is substantially constant over a large deformation range.

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 have reliefs interiors, for example ribs, corresponding, so as to prevent the interior surfaces of the truncated cones from sticking to each other the other at the end of 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 connection zone separates the two trunks of cone at their union, so as to spare 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 base, 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 stopper is described as consisting of two truncated cones joined by their large base, the shape may deviate from it, for example by rounding off, so as to form two opposite basins possibly constituting a sphere hollow, as long as this form is compatible with the condition that the resistant force is substantially constant over a range of deformation important.

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, referring to the attached drawings in which:
  • FIG. 1 is a perspective view from above of a stop according to the invention,
  • FIG. 2 is a perspective view from below of the same stop,
  • FIG. 3 is a view in longitudinal section and in perspective of the same stop,
  • FIG. 4 represents the force law as a function of the deformation of the stop 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 stopper 1, made entirely of rubber or elastomer, is made up of a fixing base 2 and a biconical deformable part 3 dig. The base 2 includes a cylindrical zone 4 surmounted by a zone frustoconical 5 connecting it to the deformable part 3. Under the cylindrical zone 4 a central annular stud 6 with four slots 7 is provided, comprising a conical entry 8. Straddling the cylindrical 4 and frustoconical zones 5 are made of parallel transverse openings 9 for 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 part 3 comprises two truncated cones hollow 10, 11 united by their large common base marked by a short cylindrical connection zone 16. The small base of the truncated cone upper 11 is pierced with an opening 12, making it possible to introduce a tool for fixing the base 2 by means of a screw or the like on the sash or on the chassis; the interior of the deformable part 3 is hollow and the base 2 itself has a central insert 13 for unlocking the stud fixing 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 has ribs 14, 15 arranged for example along two diametrical planes perpendicular. The lower ribs 14 are rounded at their ends upper and the upper ribs 15 are rounded at their ends lower, so that they allow the compression of the two trunks of cone towards each other during the crushing of the deformable zone, up to a maximum point where the upper ribs 15 touch the ribs lower 14 and lean against them. If the compression effort stops (when the door is open), the elasticity of the stop allows it to return to not deformed position, the risk of sticking of the interior surfaces of the truncated cones being moved apart by the ribs 14, 15.

La figure 4 montre 1a 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 force of compression (on the ordinate) as a function of the deformation (on the abscissa). We sees that the curve presents after a first climb A, a plateau B corresponding to the deformation of the two truncated cones one on the other, followed by a new climb C once the cones are crushed and bear one on the other through the ribs.
