Abstract

The invention relates to an arm for a door-check device. The large faces of the arm are covered with a covering (2, 2') made of polymer material, the thickness of which is variable in such a way that said bosses (3, 3') are formed by the variations in thickness of the covering. The arm passes through a housing, on the inside of which two metal sectors (19, 20) are pressed against the arm by two masses of elastomeric material (16, 17) connected by means of ties (18). The invention is used particularly for vehicle doors. <IMAGE>

Description

L'invention concerne un dispositif d'arrêt frottant de porte notamment pour une porte de véhicule.The invention relates to a door rubbing stop device in particular for a vehicle door.

On connaît des dispositifs d'arrêt de porte de type frottant essentiellement constitués d'un tirant dont une extrémité est apte à être articulée à la porte et dont l'autre extrémité est libre, et d'un boîtier, fixé au bâti de la porte, qui contient des corps de friction disposés dans le boîtier de part et d'autre d'un passage qui traverse le boîtier et dans lequel peut glisser le tirant, ces corps de friction étant pressés contre le tirant par des moyens élastiques, et le tirant présentant des bossages latéraux qui, en coopérant avec les corps de friction, déterminent des positions d'arrêt du tirant et, par conséquent, des positions d'arrêt de la porte. Un tel dispositif est décrit par exemple dans le brevet FR-A 1 143 995.Friction type door stop devices are known which essentially consist of a tie rod, one end of which is capable of being hinged to the door and the other end of which is free, and of a housing fixed to the frame of the door. , which contains friction bodies arranged in the housing on either side of a passage which passes through the housing and into which the tie rod can slide, these friction bodies being pressed against the tie rod by elastic means, and the tie rod having lateral bosses which, in cooperation with the friction bodies, determine stop positions of the tie rod and, consequently, stop positions of the door. Such a device is described for example in patent FR-A 1 143 995.

On connaît par le document GB-A-2 229 668 un dispositif d'arrêt frottant de porte, notamment pour une porte de véhicule, qui comporte un tirant longitudinal avec des faces planes et un boîtier qui constitue une chambre contenant des corps de friction disposés de part et d'autre d'un passage qui traverse le boîtier et dans lequel peut glisser le tirant, ces corps de friction étant pressés contre le tirant par des moyens élastiques situés dans la chambre. Dans ce document, le tirant est constitué par un insert métallique longitudinal et plat dont les grandes faces sont recouvertes d'un revêtement en matière polymère dont l'epaisseur est variable pour former des bossages sur les faces planes du tirant, ces bossages étant aptes à déterminer des positions d'arrêt du tirant, les corps de pression sont constitués par des roulements et les moyens élastiques sont constitués par des ressorts. Un tel dispositif est de construction complexe et de fonctionnement bruyant.Document GB-A-2 229 668 discloses a door rubbing stop device, in particular for a vehicle door, which comprises a longitudinal tie rod with flat faces and a housing which constitutes a chamber containing friction bodies arranged on either side of a passage which passes through the housing and into which the tie rod can slide, these friction bodies being pressed against the tie rod by elastic means located in the chamber. In this document, the tie rod is constituted by a flat longitudinal metal insert, the large faces of which are covered with a coating of polymer material, the thickness of which is variable to form bosses on the flat faces of the tie rod, these bosses being suitable for determine stop positions of the tie rod, the bodies of pressure are constituted by bearings and the elastic means are constituted by springs. Such a device is of complex construction and noisy operation.

La présente invention a pour objet d'améliorer un tel dispositif, notamment pour le rendre moins bruyant, moins sensible à l'usure et tel que l'usure ne constitue pas un risque de corrosion.The object of the present invention is to improve such a device, in particular to make it less noisy, less sensitive to wear and such that wear does not constitute a risk of corrosion.

La présente invention y parvient grâce aux caractéristiques énoncées dans la revendication 1.The present invention achieves this by virtue of the features set out in claim 1.

On décrira ci-après un exemple d'un dispositif d'arrêt de porte conforme à l'invention, en référence aux figures du dessin joint, et la description et les figures feront apparaître d'autres particularités de l'invention.An example of a door stop device according to the invention will be described below, with reference to the figures of the attached drawing, and the description and the figures will reveal other particularities of the invention.

Sur les figures :

  • la figure 1 est une coupe longitudinale du dispositif selon le plan I-I de la figure 2 ;
  • la figure 2 est une coupe suivant le plan II-II de la figure 1 ;
  • la figure 3 est une perspective éclatée du dispositif ;
  • la figure 4 est un schéma d'un exemple d'implantation du dispositif, et
  • la figure 5 est un schéma montrant différentes positions du tirant au cours du fonctionnement du dispositif.
In the figures:
  • Figure 1 is a longitudinal section of the device according to the plane II of Figure 2;
  • Figure 2 is a section along the plane II-II of Figure 1;
  • Figure 3 is an exploded perspective of the device;
  • FIG. 4 is a diagram of an example of installation of the device, and
  • Figure 5 is a diagram showing different positions of the tie rod during operation of the device.

Le dispositif d'arrêt de porte représenté sur les figures 1 à 3 est constitué d'un tirant T et d'un boîtier B.The door stop device shown in Figures 1 to 3 consists of a tie rod T and a housing B.

Le tirant T est constitué d'un plat longitudinal en acier 1 d'épaisseur constante dont les deux grandes faces 2,2' opposées sont recouvertes d'un revêtement en matière polymère, de préférence en une matière polyamide. L'épaisseur du revêtement est variable ; cette variation d'épaisseur détermine des bossages 3,3' répartis sur la longueur du tirant T, de façon connue en soi. Les petits côtés du tirant T sont de préférence également enrobés de la matière polymère.The tie rod T consists of a longitudinal steel plate 1 of constant thickness, the two opposite large faces 2,2 ′ are covered with a coating of polymer material, preferably of a polyamide material. The thickness of the coating is variable; this thickness variation determines bosses 3.3 ′ distributed over the length of the tie rod T, in a manner known per se. The short sides of the tie rod T are preferably also coated with the polymeric material.

A une extrémité, le tirant T comporte un orifice 4 pour son montage sur le bâti d'une porte (ou sur la porte) et, à son autre extrémité, le tirant T comporte un ensemble de butée constitué par exemple d'un amortisseur élastique 5 et renfort métallique 6 qui sont enfilés sur le tirant T et maintenus par une clavette 7 passant dans un orifice 8 du tirant.At one end, the tie-rod T comprises an orifice 4 for its mounting on the frame of a door (or on the door) and, at its other end, the tie-rod T comprises a stop assembly consisting for example of an elastic damper 5 and metal reinforcement 6 which are threaded on the tie rod T and held by a key 7 passing through an orifice 8 of the tie rod.

Le boîtier B est constitué d'un fond 9 et d'un couvercle 10 qui comporte des orifices 11 coopérant pour le passage de vis 12 servant à fixer le boîtier à la porte (ou au bâti de la porte). Le fond 9 et le couvercle 10 coopèrent pour déterminer une chambre interne et sont munis de deux lumières en vis-a-vis 13,14 aptes à laisser passer le tirant T qui peut ainsi traverser la chambre.The housing B consists of a bottom 9 and a cover 10 which has orifices 11 cooperating for the passage of screws 12 serving to fix the housing to the door (or to the frame of the door). The bottom 9 and the cover 10 cooperate to determine an internal chamber and are provided with two facing lights 13,14 capable of letting the tie rod T which can thus pass through the chamber.

Dans la chambre, est contenu un corps 15 en matière élastomère constitué de deux masses 16,17 de forme générale parallélépipédique en vis-à-vis réunies par des ligaments 18 qui déterminent entre eux et entre les deux masses 16,17 un espace suffisant pour loger deux secteurs métalliques 19,20 et pour laisser passer entre les secteurs le tirant T introduit dans les lumières 13,14.In the chamber, there is contained a body 15 of elastomeric material consisting of two masses 16, 17 of generally parallelepipedal shape vis-à-vis joined by ligaments 18 which determine between them and between the two masses 16, 17 sufficient space for accommodate two metal sectors 19,20 and to let pass between the sectors the tie T introduced in the lights 13,14.

Le volume et la conformation de la chambre sont étudiés en rapport avec la conformation des masses 16,17 et des secteurs 19,20 pour que les secteurs soient en permanence appliqués avec pression contre les grandes faces du tirant et que le corps 15 puisse se déformer élastiquement au passage des bossages du tirant sans être jamais comprimé contre les surfaces du boîtier B qui sont perpendiculaires aux grandes faces 2,2' du tirant T.The volume and the conformation of the chamber are studied in relation to the conformation of the masses 16,17 and the sectors 19,20 so that the sectors are permanently applied with pressure against the large faces of the tie rod and that the body 15 can deform elastically in the passage of the tie rod bosses without ever being compressed against the surfaces of the housing B which are perpendicular to the large faces 2,2 ′ of the tie rod T.

Dans une solution préférée, les masses 16,17 ont une base rectangulaire ou carrée et un sommet tronc-pyramidal et les faces des secteurs 19,20 qui sont au contact du tirant T ont des formes convexes adaptées au profil du tirant T.In a preferred solution, the masses 16,17 have a rectangular or square base and a trunk-pyramidal apex and the faces of the sectors 19,20 which are in contact with the tie rod T have convex shapes adapted to the profile of the tie rod T.

Les faces des masses 16,17 qui sont parallèles au sens de glissement du tirant T comportent de préférence des parties en creux et des parties en relief (par exemple des stries).The faces of the masses 16, 17 which are parallel to the direction of sliding of the tie-rod T preferably comprise recessed parts and raised parts (for example ridges).

Les bossages 3,3' du tirant T ont des pentes dont les inclinaisons sont choisies différentes selon les efforts de frottement souhaités.The bosses 3.3 ′ of the tie rod T have slopes whose inclinations are chosen to be different depending on the friction forces desired.

Durant l'ouverture ou la fermeture de la porte, le tirant T se déplace dans le boîtier B entre les deux secteurs 19,20. Les deux secteurs 19,20, en contact permanent avec le tirant T, subissent les variations d'épaisseurs du tirant T (bossages) comprimant les masses 16,17 élastomères contre le boîtier B. Les efforts les plus importants ont lieu lors du passage des bossages 3,3' contre les secteurs 19,20.During the opening or closing of the door, the tie rod T moves in the housing B between the two sectors 19,20. The two sectors 19,20, in permanent contact with the tie rod T, undergo the variations in thicknesses of the tie rod T (bosses) compressing the masses 16,17 elastomers against the housing B. The greatest efforts take place during the passage of the 3.3 'bosses against sectors 19.20.

L'usure entre les secteurs 19,20 et le tirant T est subie essentiellement par le tirant T. Les pièces métalliques du boitier B (boîtier-couvercle et secteurs) ne subissent pas de corrosion car le boîtier B et le couvercle 10 ne subissent aucun frottement, donc conservent leur revêtement de protection, et les secteurs 19,20 ne sont pas usés par le tirant T. Du fait de l'absence de contact métal-métal, le dispositif ne génère aucun bruit de fonctionnement.The wear between the sectors 19,20 and the tie rod T is essentially undergone by the tie rod T. The metal parts of the housing B (housing-cover and sectors) do not undergo corrosion because the housing B and the cover 10 do not undergo any friction, therefore retain their protective coating, and the sectors 19, 20 are not worn by the tie rod T. Due to the absence of metal-metal contact, the device does not generate any operating noise.

La figure 5 illustre le fonctionnement (en soi connu) du dispositif qui permet de maintenir la porte en position fermée (I), en position d'ouverture moyenne (II) et en position d'ouverture maximale (III).FIG. 5 illustrates the operation (in itself known) of the device which makes it possible to maintain the door in the closed position (I), in the medium open position (II) and in the maximum open position (III).
