Description

La présente invention a pour objet une serrure, destinée notamment aux portes de véhicules automobiles.The present invention relates to a lock, intended in particular for the doors of motor vehicles.

On connait par le brevet français FR-A 2 402 757 une serrure de porte de véhicule automobile du type comprenant, logés dans un boîtier, une fourchette oscillante adaptée pour recevoir une gâche, un cliquet intermédiaire également monté oscillant et comportant deux bras dont l'un peut coopérer avec une extrémité de la fourchette pour bloquer celle-ci en position de verrouillage et un cliquet principal pouvant basculer entre une position où il coopère avec le cliquet intermédiaire pour bloquer celui-ci dans sa position de verrouillage de la fourchette, et une position de libération de ce cliquet intermédiaire. La serrure étant ainsi verrouillée, il suffit de faire basculer le cliquet principal pour libérer le cliquet intermédiaire, qui à son tour peut basculer dans le sens permettant la libération de la fourchette et l'ouverture de la serrure.French patent FR-A 2 402 757 discloses a motor vehicle door lock of the type comprising, housed in a housing, an oscillating fork adapted to receive a strike, an intermediate pawl also mounted oscillating and comprising two arms, the one can cooperate with one end of the fork to lock the latter in the locking position and a main pawl which can switch between a position where it cooperates with the intermediate pawl to lock the latter in its fork locking position, and a release position of this intermediate pawl. The lock being thus locked, it suffices to tilt the main pawl to release the intermediate pawl, which in turn can tilt in the direction allowing the release of the fork and the opening of the lock.

Or, au cours de la durée de service d'un véhicule, on observe l'évolution de différents facteurs, en particulier les suivants : disparition de la graisse enrobant les organes constitutifs de la serrure, apparition de poussières, détérioration des surfaces glissantes, altération des joints et des efforts qui leur sont appliqués. La conjonction de l'évolution de ces différents facteurs peut entraîner, lors de l'ouverture de la serrure, un coincement du cliquet intermédiaire, qui peut empêcher l'ouverture de la porte ou du moins gêner celle-ci, avec pour l'utilisateur, une désagréable impression à la commande (bruit, sensations de frottements, efforts plus importants, nécessité de tirer la portière dans le sens d'ouverture).However, during the service life of a vehicle, we observe the evolution of various factors, in particular the following: disappearance of the fat coating the constituent parts of the lock, appearance of dust, deterioration of slippery surfaces, deterioration joints and forces applied to them. The conjunction of the evolution of these different factors can cause, when opening the lock, a jamming of the intermediate pawl, which can prevent the opening of the door or at least hinder it, with for the user , an unpleasant impression when ordering (noise, feeling of friction, greater efforts, need to pull the door in the opening direction).

L'invention a donc pour but de résoudre ce problème afin d'éliminer toute gêne ou obstacle à l'ouverture de la serrure dans des conditions satisfaisantes, et ce pendant toute la durée de vie du véhicule.The invention therefore aims to solve this problem in order to eliminate any discomfort or obstacle to the opening of the lock under satisfactory conditions, and this throughout the life of the vehicle.

La serrure visée par l'invention est du type mentionné cu-dessus comprenant, logés dans un boîtier, une fourchette oscillante, mobile entre une position de déverrouillage vers laquelle elle est rappelée élastiquement, et une position de verrouillage dans laquelle elle coopère avec une gâche, un cliquet intermédiaire à deux bras, monté oscillant entre une position dans laquelle le premier de ses bras verrouille la fourchette dans sa position de verrouillage et une position de libération dans laquelle la fourchette est en position déverrouillée, ce cliquet intermédiaire étant élastiquement rappelé vers sa position de verrouillage de la fourchette, cette serrure comportant également un cliquet principal oscillant, susceptible de coopérer avec la partie terminale du second bras du cliquet intermédiaire pour maintenir celui-ci en appui contre la fourchette. Suivant l'invention, le cliquet principal est pourvu d'un bras adapté pour pouvoir, si la serrure est en mauvais état par suite d'un graissage insuffisant ou de la présence de poussière, pousser le second bras du cliquet intermédiaire dans le sens opposé à celui dans lequel il est rappelé élastiquement, lorsqu'on fait basculer ledit cliquet principal pour qu'il libère le cliquet intermédiaire afin d'ouvrir la serrure, de sorte que ledit bras du cliquet principal fait tourner le cliquet intermédiaire dans le sens de déverrouillage de la fourchette par ce dernier.The lock targeted by the invention is of the type mentioned above comprising, housed in a housing, an oscillating fork, movable between an unlocking position towards which it is resiliently recalled, and a locking position in which it cooperates with a keeper , an intermediate pawl with two arms, mounted oscillating between a position in which the first of its arms locks the fork in its locked position and a release position in which the fork is in the unlocked position, this intermediate pawl being resiliently biased towards its fork locking position, this lock also comprising a main oscillating pawl, capable of cooperating with the end part of the second arm of the intermediate pawl to maintain the latter in abutment against the fork. According to the invention, the main pawl is provided with an arm adapted to be able, if the lock is in poor condition due to insufficient lubrication or the presence of dust, push the second arm of the intermediate pawl in the opposite direction to the one in which it is resiliently recalled, when said main pawl is tilted so that it releases the intermediate pawl in order to open the lock, so that said main pawl arm turns the intermediate pawl in the unlocking direction of the fork by the latter.

On comprend dans ces conditions que les facteurs mentionnés ci-dessus et qui s'opposent à l'ouverture normale de la serrure, deviennent inopérants et que l'ouverture satisfaisante de la serrure est ainsi garantie.It is understood under these conditions that the factors mentioned above and which oppose the normal opening of the lock, become ineffective and that the satisfactory opening of the lock is thus guaranteed.

D'autres particularités et avantages de l'invention apparaitront au cours de la description qui va suivre, faite en référence aux dessins annexés qui en illustrent à titre d'exemple non limitatif un mode de réalisation :

  • - la Figure 1 est une vue en élévation d'un mode de réalisation de la serrure selon l'invention en position verrouillée, le boîtier n'étant pas présenté pour simplifier le dessin;
  • - la Figure 2 est une vue en élévation analogue à la Figure 1 montrant la première phase du déverrouillage de la fourchette à partir de la position de la Figure 1, le cliquet principal étant relevé;
  • - la Figure 3 illustre la seconde phase de l'ouverture de la serrure, dans laquelle le bras du cliquet principal fait basculer le cliquet intermédiaire dans le sens qui autorise la libération de la fourchette;
  • - la Figure 4 illustre la phase suivante de l'ouverture, dans laquelle après libération par le cliquet intermédiaire, la fourchette a complètement basculé et la gâche est libérée;
  • - la Figure 5 montre la serrure en condition d'ouverture complète, après retour du cliquet principal en appui sur le cliquet intermédiaire.
Other features and advantages of the invention will appear during the description which follows, given with reference to the appended drawings which illustrate by way of nonlimiting example an embodiment:
  • - Figure 1 is an elevational view of an embodiment of the lock according to the invention in the locked position, the housing not being presented to simplify the drawing;
  • - Figure 2 is an elevational view similar to Figure 1 showing the first phase of unlocking the fork from the position of Figure 1, the main pawl being raised;
  • - Figure 3 illustrates the second phase of the opening of the lock, in which the arm of the main pawl swings the intermediate pawl in the direction which allows the release of the fork;
  • - Figure 4 illustrates the next phase of opening, in which after release by the intermediate pawl, the fork has completely tilted and the keeper is released;
  • - Figure 5 shows the lock in full opening condition, after return of the main pawl pressing on the intermediate pawl.

La serrure représentée aux dessins est destinée en particulier aux portes de véhicules automobiles, et comprend, logés dans un boîtier 10, les élé ments suivants :

  • - une fourchette 1 montée oscillante sur un axe 2, cette fourchette présentant un évidement 3 adapté pour recevoir une gâche 4, et étant rappelée élastiquement vers sa position de déverrouillage de la serrure (Figure 5) par un ressort 5 coaxial à l'axe 2;
  • - un cliquet intermédiaire 6 à deux bras 7, 8 montés oscillants autour d'un axe 9 et rappelés élastiquement par un ressort 11 enroulé autour de cet axe vers une position où le bec terminal 7a de son premier bras 7 s'engage dans une encoche périphérique 12 d'une branche 13 de la fourchette 1, en maintenant cette dernière en position verrouillée (Figure 1) dans laquelle elle emprisonne la gâche 4 dans son évidement 3;
  • - un cliquet principal 14 également monté oscillant autour d'un axe 15 et élastiquement sollicité par un ressort 16 enroulé autour de cet axe vers une position dans laquelle un bec terminal 17 de ce cliquet 14 vient en appui contre la partie terminale 8a du second bras 8, afin de maintenir le cliquet intermédiaire 6 dans sa position de verrouillage de la fourchette 1 (Figure 1).
The lock shown in the drawings is intended in particular for the doors of motor vehicles, and comprises, housed in a housing 10, the following elements:
  • - A fork 1 mounted oscillating on an axis 2, this fork having a recess 3 adapted to receive a keeper 4, and being resiliently returned to its unlocking position of the lock (Figure 5) by a spring 5 coaxial with the axis 2 ;
  • - An intermediate pawl 6 with two arms 7, 8 mounted oscillating around an axis 9 and elastically returned by a spring 11 wound around this axis to a position where the terminal spout 7a of its first arm 7 engages in a notch device 12 of a branch 13 of the fork 1, while maintaining the latter in the locked position (Figure 1) in which it traps the keeper 4 in its recess 3;
  • a main pawl 14 also mounted oscillating around an axis 15 and elastically urged by a spring 16 wound around this axis towards a position in which a terminal spout 17 of this pawl 14 comes to bear against the end part 8a of the second arm 8, in order to maintain the intermediate pawl 6 in its locking position of the fork 1 (Figure 1).

Les axes 2, 9 et 15 sont fixés au boîtier 10, et les ressorts de rappel correspondants 5, 11, 16 ont leurs extrémités fixées d'une part au boîtier et d'autre part aux éléments 1, 6, 14 qu'ils sollicitent en rotation.The axes 2, 9 and 15 are fixed to the housing 10, and the corresponding return springs 5, 11, 16 have their ends fixed on the one hand to the housing and on the other hand to the elements 1, 6, 14 that they stress in rotation.

Dans la position de verrouillage de la serrure représentée à la Figure 1, la gâche 4 est sollicitée contre le fond arrondi de l'évidement 3, c'est-à-dire vers la droite sur le dessin, par la réaction F des joints de portière, et elle est retenue par la fourchette 1, maintenue en position verrouillée par le cliquet intermédiaire 6. L'effort de contact F1 de la fourchette 1 sur le cliquet 6 tend à faire tourner ce dernier dans le sens horaire R contre la force de rappel de son ressort 11, c'est-à-dire dans le sens du déverrouillage. Le cliquet principal 14 a pour fonction d'empêcher le déverrouillage de la serrure en verrouillant le cliquet intermédiaire 6 par son bec terminal 17, qui exerce sur l'extrémité 8a du cliquet 6 un effort F2 passant par l'axe de rotation du cliquet principal 14.In the locking position of the lock shown in Figure 1, the keeper 4 is pressed against the rounded bottom of the recess 3, that is to say to the right in the drawing, by the reaction F of the seals door, and it is retained by the fork 1, held in the locked position by the intermediate pawl 6. The contact force F1 of the fork 1 on the pawl 6 tends to rotate the latter clockwise R against the force of reminder of its spring 11, that is to say in the unlocking direction. The main pawl 14 has the function of preventing the unlocking of the lock by locking the intermediate pawl 6 by its end spout 17, which exerts on the end 8a of the pawl 6 a force F2 passing through the axis of rotation of the main pawl 14.

Du fait du rapport des bras de levier du cliquet intermédiaire 6, déterminé par les deux bras 7 et 8, l'effort F2 ne représente qu'une faible proportion de l'effort F. De plus, l'effort F2 provoque sur le cliquet principal 14 l'apparition d'un couple qui tend à faire tourner celui-ci dans le sens horaire, c'est-à-dire que ce couple maintient le cliquet principal 14 en position verrouillée.Due to the ratio of the lever arms of the intermediate pawl 6, determined by the two arms 7 and 8, the force F2 represents only a small proportion of the force F. In addition, the force F2 causes on the pawl main 14 the appearance of a torque which tends to rotate it clockwise, that is to say that this couple maintains the main pawl 14 in the locked position.

Le cliquet principal 14 est constitué de deux bras 18, 19 le premier bras 18 présentant à son extrémité le bec 17 de verrouillage du cliquet 6. Le second bras 19 forme avec le bras 18 un coude, et est muni à son extrémité d'un bossage 19a susceptible de venir en appui contre le second bras 8 du cliquet intermédiaire 6 durant l'ouverture de la serrure.The main pawl 14 consists of two arms 18, 19 the first arm 18 having at its end the catch 17 for locking the pawl 6. The second arm 19 forms with the arm 18 an elbow, and is provided at its end with a boss 19a capable of coming to bear against the second arm 8 of the intermediate pawl 6 during the opening of the lock.

La séquence d'ouverture de la serrure est la suivante :The sequence for opening the lock is as follows:

La serrure étant dans la condition verrouillée représentée à la Figure 1, on soulève par un moyen extérieur connu en soi et non représenté le cliquet principal 14, en le faisant tourner dans le sens anti-horaire AR, jusqu'à ce qu'il libère complètement le cliquet intermédiaire 6, cette situation étant représentée à la Figure 2.The lock being in the locked condition represented in FIG. 1, the main pawl 14 is lifted by an external means known per se and not shown, by rotating it anti-clockwise AR, until it releases the intermediate pawl 6 completely, this situation being shown in Figure 2.

A ce moment, l'effort F2 a disparu, et seul subsiste l'effort F1 qui tend à faire tourner le cliquet intermédiaire 6 dans le sens de déverrouillage (sens horaire sur les dessins). En même temps, du fait du basculement du cliquet principal 14, le bossage 19a de son bras 19 vient en contact avec le bras 8 du cliquet 6 (Figure 2).At this time, the force F2 has disappeared, and only the force F1 remains, which tends to rotate the intermediate pawl 6 in the unlocking direction (clockwise in the drawings). At the same time, due to the tilting of the main pawl 14, the boss 19a of its arm 19 comes into contact with the arm 8 of the pawl 6 (Figure 2).

Si la serrure est en bon état d'entretien (graissage convenable, absence de poussière, etc...), dès que la position de la Figure 2 est atteinte, l'effort F1 est suffisant pour faire basculer le cliquet intermédiaire 6 dans le sens horaire et pour déverrouiller la serrure. Si la serrure est grippée par suite d'un mauvais état (graissage insuffisant, poussière,...), l'effort F1 n'est pas suffisant, et le basculement du cliquet principal 14 se poursuivant, le bossage 19a pousse le cliquet intermédiaire 6 en le faisant basculer dans le sens horaire (Figure 3) de sorte que son bec 7a se retire de l'encoche 12 et commence à libérer la fourchette 1 (Figure 3).If the lock is in a good state of maintenance (suitable lubrication, absence of dust, etc.), as soon as the position of Figure 2 is reached, the force F1 is sufficient to tilt the intermediate pawl 6 in the clockwise and to unlock the lock. If the lock is seized as a result of a poor condition (insufficient lubrication, dust, etc.), the force F1 is not sufficient, and the tilting of the main pawl 14 continues, the boss 19a pushes the intermediate pawl 6 by tilting it clockwise (Figure 3) so that its beak 7a withdraws from the notch 12 and begins to release the fork 1 (Figure 3).

Dans la phase suivante (Figure 4), la branche 13 de la fourchette 1 a complètement échappé au bras 7 du cliquet intermédiaire 6, de sorte que sous l'effet de son ressort de rappel 5, la fourchette 1 ainsi libérée bascule dans le sens anti-horaire et libère complètement la gâche 4. Dans cette condition, le bec terminal 7a reste appliqué contre la surface de la fourchette 1 sous l'effet du ressort de rappel 11 et plus précisément sur la branche de la fourchette 1 opposée à sa branche 13 par rapport à l'évidement 3. D'autre part, l'effort de manoeuvre exercé sur le cliquet principal 14 maintient son bossage 19a en appui sur la branche 8 du cliquet 6.In the next phase (Figure 4), the branch 13 of the fork 1 has completely escaped the arm 7 of the intermediate pawl 6, so that under the effect of its return spring 5, the fork 1 thus released tilts in the direction anti-clockwise and completely releases the keeper 4. In this condition, the terminal spout 7a remains applied against the surface of the fork 1 under the effect of the return spring 11 and more precisely on the branch of the fork 1 opposite its branch 13 with respect to the recess 3. On the other hand, the operating force exerted on the main pawl 14 maintains its boss 19a in abutment on the branch 8 of the pawl 6.

Lorsqu'on libère le cliquet principal 14 (Figure 5), celui-ci bascule dans le sens horaire sous l'action de son ressort de rappel 16, de sorte que son bosa- ge 19a s'écarte de la branche 8 et que son bras 18 revient en appui par son extrémité 17, sur la partie terminale 8a du cliquet 6.When the main pawl 14 (Figure 5) is released, it ratchets clockwise under the action of its return spring 16, so that its boss 19a moves away from branch 8 and its arm 18 comes to bear at its end 17, on the terminal part 8a of the pawl 6.

La serrure est alors complètement ouverte et peut être verrouillée par une séquence inverse de celle qui vient d'être décrite, si l'on rapproche la serrure de la gâche 4 de façon à faire pénétrer celle-ci dans l'évidement 3.The lock is then completely open and can be locked by a sequence opposite to that which has just been described, if the lock is brought closer to the keeper 4 so as to make it penetrate into the recess 3.
