Description

La présente invention a pour objet un dispositif d'arrêt pour porte pivotante, notamment pour porte de véhicule automobile, comportant un bras destiné à être monté pivotant sur l'une des parties constituées par la porte et par le montant fixe sur lequel la porte est montée, ce bras ayant la forme d'une lame, au contact des deux bords opposés de laquelle sont appliqués deux galets dont l'un est fixe et l'autre, mobile, est soumis à une action élastique qui crée une pression de contact entre chacun des deux galets et le bras, ce dernier étant pourvu d'un cran d'arrêt pour la retenue du galet fixe dans la position d'ouverture de la porte.The present invention relates to a stop device for a pivoting door, in particular for a motor vehicle door, comprising an arm intended to be pivotally mounted on one of the parts constituted by the door and by the fixed upright on which the door is mounted, this arm having the shape of a blade, in contact with the two opposite edges of which are applied two rollers, one of which is fixed and the other, mobile, is subjected to an elastic action which creates a contact pressure between each of the two rollers and the arm, the latter being provided with a catch for retaining the fixed roller in the open position of the door.

Dans les dispositifs d'arrêt de porte connus de ce type (voir notamment FR-A-2478 177; FR-A-2 439 285 ; FR-A-1 601 092 ; et FR-A-1 133 128) les galets utilisés sont des galets pleins qui, étant soumis à une usure d'autant moins évitable qu'ils ne sont pas à l'abri de la poussière et des intempéries, exigent un graissage périodique, faute duquel le dispositif d'arrêt deviendrait inopérant au bout d'un temps relativement court.In the known door stop devices of this type (see in particular FR-A-2478 177; FR-A-2 439 285; FR-A-1 601 092; and FR-A-1 133 128) the rollers used are solid rollers which, being subject to wear which is all the less avoidable as they are not protected from dust and weather, require periodic lubrication, failing which the stop device would become inoperative after 'a relatively short time.

Le but de l'invention est en conséquence de proposer un dispositif d'arrêt de porte qui puisse avoir une longue durée de vie sans qu'un graissage soit nécessaire.The object of the invention is therefore to provide a door stop device which can have a long service life without lubrication being necessary.

Ce but est atteint, suivant l'invention, par une disposition suivant laquelle chaque galet se compose de deux bagues cylindriques emboîtées l'une dans l'autre, qui comportent chacune à l'une de leurs extrémités une collerette plane orientée radialement vers l'extérieur, la collerette de la bague interne ayant une dimension radiale telle qu'elle fait saillie sur la surface cylindrique de la bague externe et qu'ainsi un contact glissant peut s'établir, non seulement radialement entre les deux bagues, mais encore axialement entre les collerettes et les faces externes respectives du bras.This object is achieved, according to the invention, by an arrangement according to which each roller consists of two cylindrical rings nested one inside the other, which each have at one of their ends a flat collar oriented radially towards the outer, the flange of the inner ring having a radial dimension such that it protrudes from the cylindrical surface of the outer ring and that thus a sliding contact can be established, not only radially between the two rings, but also axially between the flanges and the respective external faces of the arm.

Du fait de la présence de deux bagues, si l'une d'elles est bloquée dans son mouvement de rotation, en raison par exemple d'un grippage, l'autre bague assure la rotation sans que soit perturbée la fonction du dispositif. De plus le guidage latéral du bras articulé, au contact de la face interne des collerettes des bagues respectives, empêche tout frottement de ce bras avec des éléments adjacents de la ferrure tels que des flancs ou branches entre lesquelles les galets sont éventuellement montés. Avec de tels éléments adjacents le contact s'établit exclusivement par la face externe des collerettes.Due to the presence of two rings, if one of them is blocked in its rotational movement, for example due to seizure, the other ring ensures the rotation without disturbing the function of the device. In addition, the lateral guidance of the articulated arm, in contact with the internal face of the flanges of the respective rings, prevents any friction of this arm with adjacent elements of the fitting such as flanks or branches between which the rollers are optionally mounted. With such adjacent elements the contact is established exclusively by the external face of the flanges.

Les deux bagues sont avantageusement munies d'un revêtement de surface en un vernis de glissement, fait d'une matière à faible coefficient de frottement, tel que le polytétrafluoroéthy- lène.The two rings are advantageously provided with a surface coating in a sliding varnish, made of a material with a low coefficient of friction, such as polytetrafluoroethylene.

Des essais d'endurance, conduits dans des conditions normales d'utilisation pratique sur un dispositif d'arrêt de porte comportant des galets composés de deux bagues munies d'un vernis de glissement, dépourvues de graissage ont permis d'obtenir après 50 000 alternances du bras articulé un fonctionnement satisfaisant du dispositif, ce qui constitue une performance remarquable si l'on observe que dans les mêmes conditions il n'a pas été possible d'aller au-delà de 5 000 alternances avec des galets pleins classiques.Endurance tests, carried out under normal conditions of practical use on a door stop device comprising rollers composed of two rings provided with a sliding varnish, devoid of greasing, made it possible to obtain after 50,000 vibrations of the articulated arm, satisfactory operation of the device, which constitutes a remarkable performance if it is observed that under the same conditions it was not possible to go beyond 5,000 vibrations with conventional solid rollers.

L'invention sera explicitée au cours de la description qui va suivre, en se référant au dessin annexé, dans lequel :

  • la figure 1 est une vue en coupe verticale d'un dispositif d'arrêt de porte comportant un bras articulé et deux galets appuyés sur les bords respectifs du bras ;
  • les figures 2, 3 et 4 sont des vues de profil, en plan et en élévation, d'une ferrure supportant les deux galets, qui est fixée sur le montant fixe par rapport auquel la porte est montée pivotante ;
  • la figure 5 est une vue en coupe, montrant le mode d'exécution des galets, qui se composent chacun de deux bagues glissantes.
The invention will be explained during the description which follows, with reference to the appended drawing, in which:
  • Figure 1 is a vertical sectional view of a door stop device comprising an articulated arm and two rollers supported on the respective edges of the arm;
  • Figures 2, 3 and 4 are side views, in plan and in elevation, of a fitting supporting the two rollers, which is fixed on the fixed amount relative to which the door is pivotally mounted;
  • Figure 5 is a sectional view showing the embodiment of the rollers, which each consist of two sliding rings.

Sur ces figures l'invention est représentée dans son application à une porte de véhicule, mais il est bien évident que le dispositif d'arrêt peut être utilisé pour d'autres organes de fermeture pivotants du véhicule, tels que le capot du moteur, le coffre, un hayon ou analogue, ou même dans d'autres types de dispositif, par exemple pour des couvercles d'appareils ménagers, de valises, de coffres et autres. Le terme « porte est employé ici dans un sens très large pour désigner ces divers organes de fermeture pivotants.In these figures the invention is shown in its application to a vehicle door, but it is obvious that the stop device can be used for other pivoting closing members of the vehicle, such as the engine hood, the trunk, tailgate or the like, or even in other types of device, for example for covers for household appliances, suitcases, chests and the like. The term "door is used here in a very broad sense to designate these various pivoting closing members.

La figure 1 représente un montant de carrosserie 1 sur lequel la porte avant gauche 3 est articulée au moyen de charnières dont l'axe 2 passe à travers deux charnons 5, fixés respectivement sur le montant 1 et sur la porte 3. Cette dernière est retenue en position d'ouverture par un dispositif d'arrêt qui comporte un bras 4 en forme de lame plate, dont l'une des extrémités est munie d'un trou 6 à travers lequel est engagé un axe d'articulation 7, parallèle à l'axe 2 et solidaire d'une chape 8 fixée à la porte 3. A proximité de cette extrémité le bras 4 comporte sur son bord avant 4a un cran d'arrêt 9 dans lequel peut être engagé, en position de fin d'ouverture, un galet 12 porté par une ferrure 14 solidarisée au moyen de boulons 16 avec l'une des parties en tôle 1a constituant le montant 1 que traverse le bras 4. Le bord avant 4a du bras 4 est pressé contre le galet 12, qui est fixe, par un galet antagoniste 13, également porté par la ferrure 14 et sollicité par un couple élastique au contract du bord arrière 4b du bras 4.FIG. 1 represents a bodywork upright 1 on which the left front door 3 is articulated by means of hinges whose axis 2 passes through two knuckles 5, fixed respectively on the upright 1 and on the door 3. The latter is retained in the open position by a stop device which comprises an arm 4 in the form of a flat blade, one of the ends of which is provided with a hole 6 through which is engaged a hinge pin 7, parallel to the axis 2 and integral with a yoke 8 fixed to the door 3. Near this end the arm 4 has on its front edge 4a a stop notch 9 in which can be engaged, in the end of opening position, a roller 12 carried by a fitting 14 secured by means of bolts 16 with one of the sheet metal parts 1a constituting the upright 1 through which the arm 4 passes. The front edge 4a of the arm 4 is pressed against the roller 12, which is fixed , by an opposing roller 13, also carried by the fitting 14 and biased by an elastic torque at contract of the rear edge 4b of the arm 4.

La ferrure 14 se présente sous la forme générale d'une platine définie par deux larges ailes planes 17, dont la forme est approximativement celle d'un quadrilatère, qui sont appliquées sur la tôle 1a et sont perforées en 17a pour permettre le passage des boulons de fixation 16. Les deux ailes 17 s'étendent symétriquement de part et d'autre d'une portion centrale 15 en forme de U, obtenue par pliage, dont les deux branches planes 18, perpendiculaires aux ailes et uniformément espacées du plan de symétrie XX, servent au montage de deux axes 19, 21, dont l'un supporte à rotation le galet fixe 12 et dont l'autre dépasse largement les branches de l'U 15 en formant deux prolongements 27 qui s'étendent au droit des ailes 17 respectives et autour de chacun desquels est engagé un enroulement hélicoïdal 28, dont l'extrémité libre est ancrée au contact d'un rebord en équerre 29 de l'aile 17 correspondante, et qui fait partie d'un ressort de torsion 31 dont la partie centrale forme un étrier 32 reliant, par l'élément transversal 30, les extrémités adjacentes des deux enroulements. Sur l'élément transversal 30 est monté rotatif le galet 13, qui est ainsi soumis directement au couple élastique produit par le ressort 31.The fitting 14 is in the general form of a plate defined by two large flat wings 17, the shape of which is approximately that of a quadrilateral, which are applied to the sheet 1a and are perforated at 17a to allow the passage of the bolts of attachment 16. The two wings 17 extend symmetrically on either side of a central portion 15 in the shape of a U, obtained by folding, the two flat branches 18, perpendicular to the wings and uniformly spaced from the plane of symmetry XX, are used for mounting two axes 19, 21, one of which rotatably supports the fixed roller 12 and the other of which protrudes largely the branches of the U 15 by forming two extensions 27 which extend in line with the respective wings 17 and around each of which is engaged a helical winding 28, the free end of which is anchored in contact with a square edge 29 of the corresponding wing 17, and which is part of a torsion spring 31, the central part of which forms a stirrup 32 connecting, by the transverse element 30, the adjacent ends of the two windings. On the transverse element 30 is rotatably mounted the roller 13, which is thus directly subjected to the elastic torque produced by the spring 31.

La traverse 26 de la portion centrale 15 en forme de U est à peu près perpendiculaire aux ailes 17 et est située en position marginale par rapport à elles, de sorte que le bras 4 peut se déplacer entre les branches 18 sans qu'il y ait interférence avec la traverse 26 dont il est constamment espacé.The crosspiece 26 of the central portion 15 in the shape of a U is approximately perpendicular to the wings 17 and is located in a marginal position relative to them, so that the arm 4 can move between the branches 18 without there being interference with the cross member 26 from which it is constantly spaced.

Suivant l'invention, et comme le montre à plus grande échelle la figure 5, chacun des galets 12, 13 se compose de deux bagues cylindriques 46, 47, en acier traité, qui comportent chacune à l'une de leurs extrémités une collerette plane 56, 57 orientée radialement vers l'extérieur, et qui sont emboîtées l'une dans l'autre. La dimension radiale de la collerette 56 de la bague interne 46 est telle qu'elle fait saillie sur la surface cylindrique de la bague externe 47. Les deux bagues ont donc un contact glissant, radialement, entre leurs surfaces cylindriques adjacentes et peuvent, le cas échéant, avoir aussi un contact glissant axialement, entre l'extrémité dépourvue de collerette de la bague externe 47 et la collerette 56 de la bague interne. Un revêtement 58 en polytétrafluo- roéthylène, ou en une autre matière à faible coefficient de frottement, est appliqué superficiellement sur les deux bagues 46, 47, pour améliorer les caractéristiques de glissement non seulement entre les deux bagues, mais encore entre la bague interne 46 et l'axe 19, ou l'élément 30, et entre les collerettes 56, 57 et, d'une part, les faces internes 18a, 18b des branches 18 de la ferrure 14, d'autre part, les faces latérales 4c, 4d du bras articulé 4.According to the invention, and as shown on a larger scale in Figure 5, each of the rollers 12, 13 consists of two cylindrical rings 46, 47, of treated steel, which each have at one of their ends a flat collar 56, 57 oriented radially outwards, and which are fitted one inside the other. The radial dimension of the flange 56 of the inner ring 46 is such that it protrudes from the cylindrical surface of the outer ring 47. The two rings therefore have sliding contact, radially, between their adjacent cylindrical surfaces and can, if necessary if necessary, also have an axially sliding contact, between the end without the flange of the outer ring 47 and the flange 56 of the inner ring. A coating 58 of polytetrafluoroethylene, or of another material with a low coefficient of friction, is applied surface to the two rings 46, 47, to improve the sliding characteristics not only between the two rings, but also between the internal ring 46 and the axis 19, or the element 30, and between the flanges 56, 57 and, on the one hand, the internal faces 18a, 18b of the branches 18 of the fitting 14, on the other hand, the lateral faces 4c, 4d of the articulated arm 4.

Sous l'action du couple exercé par la traverse 30 du ressort 31 les deux galets 12 et 13 sont appliqués sous pression au contact des bords 4a, 4b du bras 4. Dans la position de fermeture, non représentée, les deux galets sont appuyés sur une partie rectiligne des bords 4a, 4b, de sorte que le couple à exercer pour ouvrir la porte est très faible. Vers la fin de la course d'ouverture les galets 12, 13 doivent franchir respectivement le bossage à profil anguleux 10 formé sur le bord 4a et la zone 11 à courbure convexe du bord 4b, avant que le galet 12 tombe finalement dans le cran d'arrêt 9 qui le retient positivement, par son flanc terminal 9a, comme représenté à la figure 1. Pour fermer la porte à partir de cette position de pleine ouverture, il est nécessaire d'exercer un couple relativement important à l'encontre de la retenue exercée par la rampe adjacente 10a, du bossage 10.Under the action of the torque exerted by the cross-member 30 of the spring 31, the two rollers 12 and 13 are applied under pressure in contact with the edges 4a, 4b of the arm 4. In the closed position, not shown, the two rollers are supported on a straight part of the edges 4a, 4b, so that the torque to be exerted to open the door is very low. Towards the end of the opening stroke, the rollers 12, 13 must respectively cross the angular profile boss 10 formed on the edge 4a and the zone 11 with convex curvature of the edge 4b, before the roller 12 finally falls into the notch stop 9 which retains it positively, by its end flank 9a, as shown in FIG. 1. To close the door from this fully open position, it is necessary to exert a relatively large torque against the retention exerted by the adjacent ramp 10a, of the boss 10.

Les galets 12,13, à double bague 46, 47 ont été représentés et décrits comme parties de l'exemple particulier de dispositif d'arrêt de porte, qui fait l'objet du brevet FR-A-2 478 177. Il va de soi que ces galets à double bague peuvent être utilisés dans tout dispositif d'arrêt de porte comportant un bras articulé, sur les bords duquel sont appliqués deux galets antagonistes, auquel cas les faces internes des collerettes 56, 57 ont avec les faces latérales du bras un contact glissant avec un frottement réduit, du fait que les collerettes subissent un mouvement de rotation sous l'effet du déplacement du bras.The rollers 12, 13, with double ring 46, 47 have been shown and described as parts of the particular example of a door stop device, which is the subject of patent FR-A-2 478 177. It goes from these double ring rollers can be used in any door stop device comprising an articulated arm, on the edges of which two opposing rollers are applied, in which case the internal faces of the flanges 56, 57 have with the lateral faces of the arm sliding contact with reduced friction, because the flanges undergo a rotational movement under the effect of the movement of the arm.

La constitution proposée par l'invention est particulièrement avantageuse lorsque chaque galet est monté entre deux surfaces planes parallèles, contre lesquelles les faces externes des collerettes 56, 57 ont un contact glissant. C'est ainsi que les galets suivant l'invention peuvent être appliqués au dispositif d'arrêt de porte décrit dans le brevet FR-A-2 439 285.The constitution proposed by the invention is particularly advantageous when each roller is mounted between two parallel flat surfaces, against which the external faces of the flanges 56, 57 have a sliding contact. Thus the rollers according to the invention can be applied to the door stop device described in patent FR-A-2 439 285.
