Description

SERRURE RENFORCEE POUR OUVRANT DE VEHICULE REINFORCED LOCK FOR VEHICLE OPENING
AUTOMOBILEAUTOMOBILE
[001] La présente invention concerne une serrure renforcée pour ouvrant de véhicule automobile.The present invention relates to a reinforced lock for the opening of a motor vehicle.
[002] On connaît déjà dans l'état de la technique, notamment d'après FR-A-2791 386We already know in the prior art, in particular from FR-A-2791 386
(FR-9903569), une serrure pour ouvrant de véhicule automobile, du type comprenant un pêne et un cliquet de blocage de ce pêne montés articulés sur un support chacun autour d'un axe géométrique matérialisé par une broche, chaque broche d'articulation étant munie d'une première extrémité liée au support, au moins une broche d'articulation du pêne ou du cliquet, dite broche renforcée, étant munie d'une seconde extrémité liée à une platine de renfort.(FR-9903569), a lock for a motor vehicle opening, of the type comprising a bolt and a locking pawl for this bolt mounted articulated on a support each around a geometric axis materialized by a pin, each articulation pin being provided with a first end linked to the support, at least one pin for hinging the bolt or the pawl, called a reinforced pin, being provided with a second end linked to a reinforcing plate.
[003] Habituellement, les axes des broches d'articulation du pêne et du cliquet sont sensiblement parallèles et les premières extrémités de ces broches sont liées à une partie du support sensiblement perpendiculaires aux axes de ces broches.Usually, the axes of the pins of articulation of the bolt and the pawl are substantially parallel and the first ends of these pins are connected to a part of the support substantially perpendicular to the axes of these pins.
[004] Dans FR-A-2791 386, les broches d'articulation du pêne et du cliquet sont munies chacune d'une seconde extrémité liée à la platine de renfort.In FR-A-2791 386, the pins of articulation of the bolt and the pawl are each provided with a second end linked to the reinforcing plate.
[005] Le pêne est destiné à coopérer avec une gâche pour maintenir l'ouvrant dans une position fermée. En cas de choc tendant à déformer la serrure, la platine de renfort forme des moyens de retenue des broches d'articulation dans leur position perpendiculaire au support. En évitant des variations excessives de l'orientation des broches d'articulation du pêne et du cliquet lors d'un choc, la platine de renfort optimise la solidité de la liaison entre la gâche et le pêne de façon à éviter l'ouverture intempestive de l'ouvrant.The bolt is intended to cooperate with a keeper to maintain the opening in a closed position. In the event of a shock tending to deform the lock, the reinforcing plate forms means for retaining the articulation pins in their position perpendicular to the support. By avoiding excessive variations in the orientation of the pins of articulation of the bolt and the pawl during an impact, the reinforcing plate optimizes the solidity of the connection between the strike and the bolt so as to avoid inadvertent opening of opening.
[006] L'invention a notamment pour but d'optimiser davantage la liaison entre la gâche et le pêne lors d'un choc au cours duquel apparaissent en particulier des efforts de déformations de la serrure sensiblement perpendiculaires à l'axe d'une broche d'articulation du pêne ou du cliquet.The invention particularly aims to further optimize the connection between the strike and the bolt during an impact during which appear in particular stresses of the lock deformations substantially perpendicular to the axis of a spindle hinge bolt or ratchet.
[007] A cet effet, l'invention a pour objet une serrure pour ouvrant de véhicule automobile, selon la revendication 1.To this end, the invention relates to a lock for a motor vehicle door, according to claim 1.
[008] En cas de choc, la coopération de l'œillet de la platine avec le doigt de renfort solidaire du support limite la déformation de la serrure sous l'effet des efforts sensiblement perpendiculaires à l'axe de la broche renforcée.In the event of an impact, the cooperation of the eye of the plate with the reinforcing finger secured to the support limits the deformation of the lock under the effect of forces substantially perpendicular to the axis of the reinforced pin.
[009] De préférence, avant déformation de la serrure, le doigt de renfort s'étend avec un jeu radial dans l'œillet de la platine de renfort.Preferably, before deformation of the lock, the reinforcing finger extends with a radial clearance in the eyelet of the reinforcing plate.
[010] Ce jeu radial permet de tenir compte efficacement des dispersions de cotes entre les différents éléments de la serrure et des aléas de positionnement relatif de ces éléments. [011] Suivant d'autres caractéristiques optionnelles de cette serrure :[010] This radial clearance makes it possible to effectively take into account the dispersions of dimensions between the different elements of the lock and the relative positioning hazards of these elements. According to other optional features of this lock:
[012] - l'organe de fixation est une vis coopérant par vissage avec le support ;[012] - the fixing member is a screw cooperating by screwing with the support;
[013] - la première extrémité de chaque broche d'articulation est sertie sur le support ;[013] - the first end of each hinge pin is crimped onto the support;
[014] - les broches d'articulation du pêne et du cliquet sont munies chacune d'une seconde extrémité liée à la platine de renfort ; [015] - la seconde extrémité de chaque broche d'articulation est sertie sur la platine de renfort ; [016] - la platine de renfort est munie de deux œillets entourant chacun un doigt de renfort solidaire du support ; [017] - les axes des broches d'articulation du pêne et du cliquet sont sensiblement parallèles ; [018] - le support portant le pêne est solidaire d'un premier élément parmi l'ouvrant et un dormant, le pêne étant : destiné à coopérer avec une gâche, portée par le second élément parmi l'ouvrant et le do mant, et monté pivotant sur le support entre au moins deux positions dites de fermeture au premier cran et de fermeture au second cran dans lesquelles le pêne coopère avec la gâche ; [019] - le support est solidaire de l'ouvrant et la gâche est portée par le dormant.[014] - the hinge pins of the bolt and the pawl are each provided with a second end linked to the reinforcing plate; [015] - the second end of each hinge pin is crimped onto the reinforcing plate; [016] - the reinforcing plate is provided with two eyelets each surrounding a reinforcing finger secured to the support; [017] - the axes of the pins of articulation of the bolt and the pawl are substantially parallel; The support carrying the bolt is secured to a first element among the opening and a frame, the bolt being: intended to cooperate with a keeper, carried by the second element among the opening and the do mant, and pivotally mounted on the support between at least two positions called closing at the first notch and closing at the second notch in which the bolt cooperates with the keeper; [019] - the support is secured to the opening and the keeper is carried by the frame.
[020] L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins dans lesquels :The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the drawings in which:
- la figure 1 est une vue en perspective d'une serrure selon l'invention ;- Figure 1 is a perspective view of a lock according to the invention;
- la figure 2 est une vue similaire à la figure 2 partiellement éclatée ;- Figure 2 is a view similar to Figure 2 partially exploded;
- la figure 3 est une vue en coupe de la serrure selon l'invention, le plan de coupe passant par les axes des broches d'articulation des pêne et cliquet et l'axe d'un doigt de renfort.- Figure 3 is a sectional view of the lock according to the invention, the cutting plane passing through the axes of the pins of articulation of the bolt and pawl and the axis of a reinforcing finger.
[021 ] On a représenté sur les figures une serrure pour un ouvrant de véhicule automobile, selon l'invention, désignée par la référence générale 10. [022] L'ouvrant, désigné sur la figure 3 par la référence 12, est par exemple une porte du véhicule. L'ouvrant 12 est associé à un dormant, non représenté sur les figures, solidaire du corps du véhicule. T023] De façon classique, la serrure 10 comprend un pêne rotatif 14 destiné à coopérer avec une gâche 16, en forme générale d'étrier, représentée sur la figure 1. [024] Dans l'exemple illustré, le pêne 14 est porté par une partie 18 de l'ouvrant, appelée généralement caisson (voir figure 3), et la gâche 16 est portée par le dormant. [0251 La serrure 10 comprend également un support appelé contre-plaque 20 destinée à être fixée sur la plaque 18 de l'ouvrant. La contre-plaque 20 est donc solidaire de l'ouvrant.[021] There is shown in the figures a lock for an opening of a motor vehicle, according to the invention, designated by the general reference 10. [022] The opening, designated in Figure 3 by the reference 12, is for example a vehicle door. The opening 12 is associated with a frame, not shown in the figures, secured to the body of the vehicle. T023] Conventionally, the lock 10 comprises a rotary bolt 14 intended to cooperate with a keeper 16, in the general shape of a stirrup, shown in FIG. 1. [024] In the example illustrated, the bolt 14 is carried by a part 18 of the opening, generally called a box (see FIG. 3), and the keeper 16 is carried by the frame. The lock 10 also includes a support called against plate 20 intended to be fixed on the plate 18 of the opening. The counter plate 20 is therefore integral with opening.
[026] Le pêne 14 est monté pivotant sur la contre-plaque 20 de façon à pouvoir être déplacé dans au moins trois positions successives dites "ouverte", "fermée au premier cran" et "fermée au second cran". L'axe géométrique de pivotement du pêne 14 est matérialisé par une broche d'articulation 22.[026] The bolt 14 is pivotally mounted on the counter plate 20 so that it can be moved into at least three successive positions called "open", "closed at the first notch" and "closed at the second notch". The geometric pivot axis of the bolt 14 is materialized by a hinge pin 22.
[027] La serrure 10 comprend également des moyens de blocage du pêne 14 dans ses positions de fermeture aux premier et second crans. Ces moyens de blocage comprennent un cliquet 24 monté pivotant sur la contre-plaque 20 autour d'un axe géométrique matérialisé par une broche d'articulation 26.[027] The lock 10 also comprises means for blocking the bolt 14 in its closed positions at the first and second notches. These blocking means comprise a pawl 24 pivotally mounted on the counter-plate 20 around a geometric axis materialized by a hinge pin 26.
[028] Les axes des broches 22, 26 d'articulation du pêne 14 et du cliquet 24 sont sensiblement parallèles.[028] The axes of the pins 22, 26 of articulation of the bolt 14 and the pawl 24 are substantially parallel.
T029] Le cliquet 24 coopère avec le pêne 14 de façon connue en soi pour immobiliser ce dernier dans ses positions de fermeture.T029] The pawl 24 cooperates with the bolt 14 in a manner known per se to immobilize the latter in its closed positions.
[030] En se référant à la figure 3, on notera que chaque broche d'articulation 22, 26 est munie d'une première extrémité 22A, 26A liée à la contre-plaque 20. Dans l'exemple décrit, la première extrémité 22A, 26A de chaque broche d'articulation 22, 26 est sertie sur la contre-plaque 20.Referring to Figure 3, it will be noted that each articulation pin 22, 26 is provided with a first end 22A, 26A linked to the counterplate 20. In the example described, the first end 22A , 26A of each articulation pin 22, 26 is crimped on the counterplate 20.
[031] On notera que les broches 22, 26 d'articulation du pêne 14 et du cliquet 24 s'étendent sensiblement perpendiculairement à une partie généralement plane de la contre-plaque 20.[031] It will be noted that the pins 22, 26 of articulation of the bolt 14 and of the pawl 24 extend substantially perpendicular to a generally flat part of the counterplate 20.
[032] La contre-plaque 20 est fixée sur la plaque 18 de préférence à l'aide de vis 28 coopérant par vissage avec des collets 30 ménagés dans la contre-plaque 20. Ces vis 28 s'étendent sensiblement parallèlement aux axes des broches d'articulation 22, 26.Against the plate 20 is fixed to the plate 18 preferably using screws 28 cooperating by screwing with collars 30 formed in the counter plate 20. These screws 28 extend substantially parallel to the axes of the pins hinge 22, 26.
[033] Afin d'éviter, lors d'un choc, des variations excessives de l'orientation des brochesTo avoid, during an impact, excessive variations in the orientation of the pins
22, 26 d'articulation du pêne et du cliquet, par rapport à la contre-plaque 20, chaque broche d'articulation 22, 26 est munie d'une seconde extrémité 22B, 26B liée à une platine de renfort 40.22, 26 of articulation of the bolt and the pawl, relative to the counter-plate 20, each articulation pin 22, 26 is provided with a second end 22B, 26B linked to a reinforcing plate 40.
[034] En variante, une seule des broches d'articulation du pêne 14 ou du cliquet 24 pourrait être liée à la platine de renfort 40.[034] As a variant, only one of the hinge pins of the bolt 14 or of the pawl 24 could be linked to the reinforcing plate 40.
[035] La platine de renfort 40 est munie de deux œillets 42 entourant chacun un doigt de renfort 44 solidaire de la contre-plaque 20. Par œillet, on comprend une forme entourant tout ou partie d'un doigt de renfort 40. Les œillets 42 sont délimités, par exemple, par des collets ménagés dans la platine de renfort 40.The reinforcing plate 40 is provided with two eyelets 42 each surrounding a reinforcing finger 44 secured to the counter plate 20. By eyelet, we understand a shape surrounding all or part of a reinforcing finger 40. The eyelets 42 are delimited, for example, by collars formed in the reinforcing plate 40.
[036] Dans l'exemple illustré, chaque doigt de renfort 44 est formé par un prolongement, fileté ou non, d'une vis de fixation 28.[036] In the example illustrated, each reinforcing finger 44 is formed by an extension, threaded or not, of a fixing screw 28.
[037] En variante, la platine de renfort 40 pourrait n'être munie que d'un seul œillet 42 entourant un doigt de renfort correspondant 44.[037] Alternatively, the reinforcing plate 40 could be provided with only one eyelet 42 surrounding a corresponding reinforcing finger 44.
[038] Chaque doigt de renfort 44 est destiné, en cas de déformation de la serrure, à coopérer avec le bord de la platine 40 délimitant l'œillet correspondant 42 de façon à s'opposer aux efforts de déformation de la serrure sensiblement perpendiculaires aux axes des broches d'articulation 22, 26, ceci afin de maintenir l'orientation perpendiculaire de ces broches 22, 26 par rapport à la partie de la contre-plaque 20 auxquelles elles sont reliées.[038] Each reinforcing finger 44 is intended, in the event of deformation of the lock, to cooperate with the edge of the plate 40 delimiting the corresponding eyelet 42 so as to oppose the forces of deformation of the lock substantially perpendicular to the axes of the articulation pins 22, 26, this in order to maintain the perpendicular orientation of these pins 22, 26 relative to the part of the counterplate 20 to which they are connected.
[039] En se référant notamment à la figure 3, on voit que, avant toute déformation de la serrure, chaque doigt de renfort 44 s'étend avec un jeu radial dans l'œillet correspondant 42 de la platine 40.[039] With particular reference to FIG. 3, it can be seen that, before any deformation of the lock, each reinforcing finger 44 extends with a radial clearance in the corresponding eyelet 42 of the plate 40.
[040] L'invention ne se limite pas au mode de réalisation décrit précédemment.The invention is not limited to the embodiment described above.
[041] En particulier, les broches d'articulation 22, 26 peuvent être reliées à la contre- plaque 20 et à la platine de renfort 40 par des procédés ou moyens variés autres que le sertissage.[041] In particular, the articulation pins 22, 26 can be connected to the counter plate 20 and to the reinforcing plate 40 by various methods or means other than crimping.
[042] Par ailleurs, les doigts de renfort 44 peuvent être formés par d'autres moyens solidaires de la contre-plaque 20 que les vis 28. [042] Furthermore, the reinforcing fingers 44 can be formed by other means integral with the counterplate 20 than the screws 28.
