Description

La présente invention a pour objet un dispositif de contrôle de la fermeture d'un volet de véhicule automobile, par exemple de la porte du coffre arrière, qui indique au conducteur si le volet est vraiment complètement fermé, et plus particulièrement un dispositif de ce type qui ne présente aucune saillie de façon à éviter tout risque d'accrochage avec un objet tel qu'un bagage.The subject of the present invention is a device for controlling the closing of a motor vehicle shutter, for example of the rear trunk door, which indicates to the driver if the shutter is really completely closed, and more particularly a device of this type. which has no projection so as to avoid any risk of catching on with an object such as luggage.

Le dispositif de contrôle selon l'invention comporte un interrupteur qui commande un voyant de contrôle, dont deux éléments peuvent être mis ou non en contact électrique l'un avec l'autre, et qui est actionné par la serrure du volet, cette serrure comprenant un pêne monté sur le volet ou la caisse du véhicule et un élément de gâche monté sur la caisse ou le volet et dont une partie pénètre dans une échancrure du pêne lorsque le volet est fermé. Il est caractérisé en ce que l'un au moins des éléments de l'interrupteur est incorporé au pêne.The control device according to the invention comprises a switch which controls a control light, two elements of which may or may not be brought into electrical contact with each other, and which is actuated by the shutter lock, this lock comprising a bolt mounted on the shutter or the body of the vehicle and a strike element mounted on the body or the shutter and part of which penetrates into a notch of the bolt when the shutter is closed. It is characterized in that at least one of the elements of the switch is incorporated in the bolt.

L'élément de gâche peut être métallique et constituer l'autre élément de l'interrupteur. Mais l'élément de gâche peut également ne pas être métallique, auquel cas les deux éléments de l'interrupteur sont incorporés au pêne.The strike element can be metallic and constitute the other element of the switch. However, the strike element may also not be metallic, in which case the two elements of the switch are incorporated into the bolt.

On a décrit ci-après, à titre d'exemples non limitatifs, trois modes de réalisation du dispositif de contrôle selon l'invention, avec référence aux dessins annexés dans lesquels:

  • Les Figures 1 et 2 montrent un premier mode de réalisation respectivement en position de repos et en position de travail;
  • La Figure 3 est un schéma électrique montrant le montage de l'interrupteur;
  • Les Figures 4 et 5 sont des vues semblables aux Figures 1 et 2 d'un second mode de réalisation;
  • Les Figures 6 et 7 sont des vues semblables aux Figures 1 et 2 d'un troisième mode de réalisation.
Three embodiments of the control device according to the invention have been described below, by way of non-limiting examples, with reference to the appended drawings in which:
  • Figures 1 and 2 show a first embodiment respectively in the rest position and in the working position;
  • Figure 3 is an electrical diagram showing the mounting of the switch;
  • Figures 4 and 5 are views similar to Figures 1 and 2 of a second embodiment;
  • Figures 6 and 7 are views similar to Figures 1 and 2 of a third embodiment.

Aux dessins, on voit une serrure propre à maintenir fermée la porte d'un coffre arrière d'un véhicule automobile. Cette serrure comprend un carter 1 dans lequel un pêne 2, en matière plastique, est monté pivotant autour d'un axe 3 en un matériau conducteur de l'électricité; ce pêne peut venir s'engager derrière un élément de gâche 4 ayant par exemple la forme d'un anneau et fixé à la caisse du véhicule, ce pêne comportant à cet effet une échancrure 2a.In the drawings, a lock suitable for keeping the door of a rear trunk of a motor vehicle is seen. This lock comprises a casing 1 in which a bolt 2, made of plastic, is pivotally mounted about an axis 3 of an electrically conductive material; this bolt can engage behind a strike element 4 having for example the shape of a ring and fixed to the body of the vehicle, this bolt comprising for this purpose a notch 2 a .

Le pêne 2 présente un logement 5 dans lequel est disposée une lame de ressort 6; cette lame est enroulée partiellement sur l'axe 3 et l'une de ses branches est en appui sur l'une des parois du logement 5; à l'état libre, quand la porte n'est pas verrouillée en position de fermeture (Figure 1), la seconde branche de la lame est en appui sur un contact 7 disposé sur une paroi du logement 5 au voisinage de l'échancrure 2a.The bolt 2 has a housing 5 in which is disposed a leaf spring 6; this blade is partially wound on the axis 3 and one of its branches is supported on one of the walls of the housing 5; in the free state, when the door is not locked in the closed position (Figure 1), the second branch of the blade is supported on a contact 7 arranged on a wall of the housing 5 in the vicinity of the notch 2 a .

Ce contact 7 est connecté à l'un des plots d'un voyant 8 disposé sur le tableau de bord et dont l'autre plot est connecté au pôle positif de la batterie 9 (Figure 3). Au repos, c'est-à-dire quand la porte est ouverte, le contact 7 se trouve connecté à la lame 6, donc à l'axe 3 et au carter 1; il est par suite à la masse et le voyant 8 est allumé.This contact 7 is connected to one of the studs of an indicator light 8 disposed on the dashboard and the other stud of which is connected to the positive pole of the battery 9 (Figure 3). At rest, that is to say when the door is open, the contact 7 is connected to the blade 6, therefore to the axis 3 and to the casing 1; it is therefore grounded and the indicator 8 is on.

Quand le pêne 2 pivote pour s'engager derrière l'anneau de gâche 4, cet anneau, en arrivant au fond de l'échancrure 2a, repousse ladite seconde branche de la lame 6 et l'écarte du contact 7 (Figure 2). Le voyant 8 s'éteint.When the bolt 2 pivots to engage behind the strike ring 4, this ring, arriving at the bottom of the notch 2 a , pushes said second branch of the blade 6 and moves it away from the contact 7 (Figure 2) . LED 8 goes out.

On peut souhaiter que le voyant 8 soit allumé non pas quand la porte est ouverte, mais quand elle est fermée.It may be desired that the indicator light 8 be lit not when the door is open, but when it is closed.

Dans le mode de réalisation des Figures 4 et 5, dans lequel la porte du coffre est en matière plastique et l'anneau 4 métallique, le contact 7 n'existe pas et le plot du voyant 8 non connecté à la batterie est connecté au carter 1. Dans ces conditions, lorsque la porte est fermée, le circuit d'alimentation du voyant est fermé par l'intermédiaire de l'anneau 4, de la lame 6 et de l'axe 3 (Figure 5). Quand la porte est ouverte, ou même fermée mais non verrouillée, la lame 6 n'est pas au contact de l'anneau 4 (Figure 4) et le voyant 8 est éteint.In the embodiment of Figures 4 and 5, in which the trunk door is made of plastic and the ring 4 is metallic, the contact 7 does not exist and the pad of the indicator light 8 not connected to the battery is connected to the casing 1. Under these conditions, when the door is closed, the indicator light supply circuit is closed by means of the ring 4, the blade 6 and the axis 3 (Figure 5). When the door is open, or even closed but not locked, the blade 6 is not in contact with the ring 4 (Figure 4) and the light 8 is off.

Dans le mode de réalisation des Figures 6 et 7 dans lequel la porte du coffre et l'anneau 4 sont métalliques, la lame 6 est remplacée par une lame 6a qui est fixée dans le logement 5 et à laquelle est connecté le plot du voyant 8 non connecté à la batterie. Lorsque la porte est fermée, la lame 6a se trouve au contact de l'anneau 4 et le second plot du voyant 8 est ainsi mis à la masse, ce qui assure l'allumage de ce voyant (Figure 7). Lorsque la porte n'est plus verrouillée en position de fermeture, la lame 6a est séparée de l'anneau 4 et le voyant 8 est éteint (Figure 6).In the embodiment of Figures 6 and 7 in which the trunk door and the ring 4 are metallic, the blade 6 is replaced by a blade 6 a which is fixed in the housing 5 and to which is connected the stud of the indicator 8 not connected to the battery. When the door is closed, the blade 6 a is in contact with the ring 4 and the second pad of the indicator light 8 is thus grounded, which ensures that this indicator light comes on (Figure 7). When the door is no longer locked in the closed position, the blade 6 a is separated from the ring 4 and the indicator light 8 is off (Figure 6).
