Description

Serrure compacte pour capot ou coffre de véhicule automobile compact lock for hood or trunk of a motor vehicle
La présente invention se rapporte à une serrure du type à arment, notamment pour le capot ou le coffre d'un véhicule automobile The present invention relates to a lock of the type with arm, particularly for the hood or the trunk of a motor vehicle
On connaît déjà, par la demande de brevet français n 2 297 977 déposée par le présent demandeur, une serrure du type ci-dessus eomprenant un boîtier porté par un élément de la carrosserie, renfermant on pène en forme de crochet pivotant et un levier pivotant de verrouillage du pène en position de fermeture, le pène et son Levier de verrouillage étant respectivement armés par des ressorts qpprapriés. already known from the French Patent Application No. 2,297,977 filed by the present applicant, a lock of the above type eomprenant a housing carried by an element of the bodywork, containing shaped one bolt swivel hook and a pivotable lever locking the bolt in the closed position, the bolt and its locking lever being armed by respective springs qpprapriés. La gâche conique, portée par l'autre élément de la carrosserie est ajourée et engagée par le pène à la fermeture. The conical striker carried by the other element of the body is perforated and engaged by the bolt when closed.

La gâche assure donc à la fois le centrage et l'accrochage de la serrure, ce qui permet de réduire l'encombrement de la serrure par l'élimination d'un organe de centrage indépendant. The keeper therefore ensures both the centering and attachment of the lock, which allows to reduce the bulk of the lock by the elimination of a separate centering member.

Cependant, en traversant le boîtier par une simple lumière, la gâche est insuffisamment guidée et bloquée et les vibrationss causées par le véhicule en mouvement, entre la afiche, le péne et le bêtier, donnent lieu à une usure prématurée de ces pièces et à un jeu grandissant et bruyant. However, crossing the housing by a single lumen, the striker is not sufficiently guided and locked and vibrationss caused by the moving vehicle, between the playing, the bolt and the bêtier give rise to premature wear of these parts and a growing and noisy play.

Par ailleurs, dans la réalisation décrite dans le brevet antérieur précité, le levier de verrouillage du pène est monté à côté du pène dans le boîtier, sur la ligne des axes de fixation du boîtier sur la carrosserie, ce qui augmente l'encombrement de l'ensemble et affai- blit la tenue de la serrure à la rétention Furthermore, in the embodiment described in the aforementioned prior patent, the bolt of the locking lever is mounted adjacent the bolt in the housing, on the line of attachment of the housing to the body axis, which increases the size of the assembly and weakens the strength of the lock retention
La présente invention a pour but d'éviter les inconvéni-its qui précèdent en proposant une serrure à armement exempte de vibrations ou de jeux parasites et présentant une rétention améliorée. The present invention aims to avoid inconvéni-its above by proposing a weapons lock without vibration or noise and games with improved retention.

A cet effet l'invention a pour objet une serrure du type ci-dessus dans laquelle le boîtier loge en outre un bloc amortisscur en matière élastique pourvu d'un logement conique revêtu d'une garostute en matériau plus rigide, par exemple en plastique ou en métal tendre, afin de centrer, guider et maintenir en pression la gâche de même conicité, sur la majeure partie de sa hauteur. To this end the invention relates to a lock of the above type wherein the housing houses a further amortisscur block of elastic material provided with a conical housing garostute coated with a more rigid material, for example plastic or soft metal, for centering, guiding and holding the pressure strike of the same conicity, over the major part of its height.

Par ailleurs, le levier de verrouillage du pène est décalé au dessus du boîtier, dans le prolongement de la gâche, ce qui permet de réduire l'entraxes des points de fixation du boîtier dont l'un des axes se confond avec l'axe de pivotement du pène. Furthermore, the bolt of the locking lever is shifted to the top of the housing, in the extension of the keeper, which reduces the distances of the fixing points of the housing of which one of the axes coincides with the axis of pivoting of the bolt.

On obtient ainsi une serrure très compacte à rétention accrue. This gives a very compact lock increased retention.

La description qui suit fait référence au dessin annexé sur lequel - les figures 1 et 2 représentent, en coupe, la serrure en positions The following description refers to the accompanying drawings in which - Figures 1 and 2 show, in section, the lock in positions
respectivement fermée et ouverte - la figure 3 est une coupe selon la ligne III de la figure i - la figure 4 est une vue de dessus selon la flèche IV de la figure 1. respectively closed and open - Figure 3 is a section along the line III of Figure i - Figure 4 is a top view along the arrow IV of Figure 1.

La serrure comprend un boîtier 1 en tôle pliée, fixé sur l'un des éléments de la carrosserie 2 par l'intermédiaire de moyens d'assemblages classiques montés à l'emplacement des axes de fixation 3, 4 représentés. The lock comprises a housing 1 folded sheet, fixed to one of the body elements 2 by means of conventional assembly means mounted at the location of fixing pins 3, 4 represented.

Le boîtier supporte un pène 5 en forme de crochet monté pivotant autour d'un axe 4 qui sert simultanément de fixation sur la carrosserie et un levier 6 de verrouillage du pène, monté pivotant autour d'un pivot 7 maintenu entre les deux extremités supérieures 3, 9 recourbées et superposées du boîtier 1 (figure 3). The housing 5 supports a bolt-shaped hook mounted to pivot about a pin 4 which simultaneously serves for fixing on the body and a lever 6 of the locking bolt, pivotally mounted about a pivot 7 held between the two upper extremities 3 9 bent and superposed the housing 1 (Figure 3).

Le pène et le levier de verrouillage sont armés par leurs ressorts respectifs 10, 11 accrochés entre chacune de ces pièces et le boîtier fixe. The bolt and the lock lever are armed by their respective springs 10, 11 hung between each of these parts and the stationary housing.

La gâche 12 conique, montée sur l'autre élément 13 de la carrosserie au moyen de vis 14 et d'une contre-plaque 15, pénètre dans le boîtier par l'extrémité opposée à celle supportant le levier de verrouillage 6, de sorte que le pivot 7 de ce dernier se situe sensiblement dans le prolongement de l'axe de la gâche 12. The striker 12 conical, mounted on the other element 13 of the body by means of screws 14 and against a plate 15, enters the housing through the end opposite that supporting the lock lever 6, so that the pin 7 of the latter is located substantially in the extension of the axis of the striker 12.

La gâche moulée, dite auto-centreuse, comporte de façon connue une lumière transversale 16, pour permettre l'engagement du pêne à la fermeture de la serrure, comme représenté sur la figure 1. The striker molded, said self-Centering machine, comprises in known manner a transverse slot 16, to permit engagement of the bolt in the closing of the lock, as shown in Figure 1.

Lors de la fermeture, le noyau extrème 17 de la gâche pénètre donc dans le crochet du pène qui pivote autour de son axe 4 tandis que le levier 6, sollicité par son ressort 11, verrouille le pêne à la fermeture par l'engagement des deux décrochements correspondants 18. When closing, the extreme core 17 of the striker thus enters the hook bolt which pivots about its axis 4, while the lever 6, biased by its spring 11, locks the bolt in closing by engagement of the two corresponding recesses 18.

Pour le déverrouillage du pène et l'ouverture de la serrure, figure 2, il suffira de faire pivoter le levier 6 en sens inversepour iibérer le pène 5 qui se détend sous l'action de son ressort 10. For unlocking the latch and opening of the lock, Figure 2, it is sufficient to rotate the lever 6 in the direction inversepour iibérer the bolt 5 which expands under the action of its spring 10.

Conformément à l'invention, le centrage, le guidage et l'amortissement de la gâche 12 sont assurés par un bloc 19 de matière élastique, par exemple en caoutchouc, pourvu d'un logement conique de même conicité que celle de la gâche et revêtu d'une garniture 20 de même forme en matériau plus rigide, par exemple en matière synthétique moulée ou en métal tendre tel que du laiton. According to the invention, the centering, guiding and damping of the keeper 12 are covered by a block 19 of resilient material, for example rubber, provided with a conical housing of the same conicity as that of the striker plate and coated a gasket 20 of the same shape and more rigid material, for example of molded synthetic material or soft metal such as brass.

Le bloc amortisseur 19 rempli l'espace intérieur du boîtier sur la majeure partie de la hauteur de la gâche engagée, sans toutefois gêner le pivotement du pène. The damper block 19 filled the interior of the housing over the major part of the height of the keeper engaged, without hinder the pivoting of the bolt. Le bloc est maintenu entre les ailes du boîtier 1, comme visible sur la figure 3. The block is maintained between the flanges of the housing 1, as shown in Figure 3.

Le revêtement 20 en plastique joue le rôle de centreur tandis que l'amortisseur 19 en caoutchouc, comprimé à la fermeture, absorbe les écarts de centrage et maintient le crochet et la gâche en pression, ce qui élimine les bruits et l'usure prématurée due aux vibrations du véhicule en marche. The coating 20 of plastic acts as a centering device 19 while the rubber damper, compressed in the closure, absorbs centering spreads and holds the hook and the striker in the pressure, which eliminates the noises and premature wear due vibration of the vehicle.

Comme on l'a vu, le boîtier 1 est muni de deux points de fixation dont l'un des axes correspond au pivot 4 du pêne. As seen, the housing 1 is provided with two fixing points, one of whose axes is the pivot 4 of the bolt. La réduction de l'entraxes 3, 4 qui en résulte permet d'obtenir une serrure plus compacte, donc plus solide et améliore encore sa rétention à l'ouverture. Reducing the distances 3, 4 that results provides a more compact lock, so stronger and further enhances its retention in the opening.
