Les appareils décrits dans les deux premières demandes de brevet citées (FRA 2 278 535 et FRA 2 373 422) présentent l'inconvénient de ne pas se déclencher automatiquement en cas de retournement ou de renversèment à vitesse réduite, de ne concerner que les véhicules équipés d'une centrale de détresse spécialisée, commandée par un interrupteur à simple contact, qui est actuellement abandonnée par les constructeurs automobilesj De plus l'appareil décrit dans la première demande de brevet, ne se déclenche que pour un choc frontal. Les appareils décrits dans les deux autres demandes de brevet.The devices described in the first two patent applications cited (FRA 2,278,535 and FRA 2,373,422) have the drawback of not being triggered automatically in the event of overturning or overturning at reduced speed, of only affecting vehicles equipped a specialized distress center, controlled by a single-contact switch, which is currently abandoned by automobile manufacturers. Furthermore, the device described in the first patent application is only triggered for a frontal impact. The devices described in the other two patent applications.
(FRA 2 381 385 et FRA 2 434470) présentent l'inconvénient de ne pas, comme ceux décrits dans les autres demandes citées ci-dessus, se déclencher en cas de renversement ou de retournement à vitesse lente, de ne pas être muni de moyen de réglage du seuil de déclenchementet de ne pas avoir de tolérance en variation, dans le temps, de l'élément magnétique. De plus, la demande de brevet FRA 2 434 470 comprend un dispositif à diodes qui engendre une très forte chute de tension.(FRA 2 381 385 and FRA 2 434470) have the disadvantage of not, like those described in the other requests cited above, being triggered in the event of a reversal or reversal at low speed, of not being provided with means setting threshold and not to have tolerance over time variation of the magnetic element. In addition, patent application FRA 2,434,470 includes a device for diodes which generates a very strong voltage drop.
On connait déjà un détecteur à bille actionnant automatiquement les feux de détresse (demande de brevet FRA 2 416 816). Son corps comporte un organe de guidage tubulaire pour une bille métallique, dans lequel, au voisinage d'une extrémité, saillissent deux contacts reliés à des conducteurs souples, destinés à être insérés dans le circuit d'alimentation des feux de détresse, un organe élastique taré, inséré dans l'organe du guidage tubulaire apte, d'une part, à maintenir la bille éloignée des contacts lorsque le véhicule roule normalement, et, d'autre part, après effacement, à appliquer la bille contre les contacts en cas de choc brutal. Ce détecteur est unidirectionnel, ne fonctionne que pour un choc frontal, et ne déclenche pas les feux de détresse en cas de retournement total ou partiel, fugitif ou permanent, pouvant survenir à vitesse réduite et sans choc. La remise de la bille dans sa position initiale n'est pas aisée, car on doit lever le capot moteur pour accéder au poussoir de remise en position. Le détecteur à bille de valeur limite d'accélération ou de décélération, selon l'invention, vise à remédier à ces inconvénients. Ce détecteur à bille, tel qu'il est caractérisé dans les revendications, résoud le problème consistant à créer un détecteur qui déclenche automatiquement les feux de détresse notamment en cas de choc, mais aussi en cas de retournement ou de renversement total ou partiel, fugitif ou permanent, pouvant survenir à vitesse réduite et sans choc.We already know a ball detector automatically activating the hazard lights (patent application FRA 2 416 816). Its body includes a tubular guide member for a metal ball, in which, in the vicinity of one end, project two contacts connected to flexible conductors, intended to be inserted in the supply circuit of the hazard warning lights, an elastic member calibrated, inserted into the tubular guide member capable, on the one hand, of keeping the ball away from the contacts when the vehicle is moving normally, and, on the other hand, after erasing, of applying the ball against the contacts in the event of brutal shock. This detector is unidirectional, works only for a frontal impact, and does not trigger the hazard lights in the event of total or partial reversal, fugitive or permanent, which may occur at reduced speed and without impact. Returning the ball to its initial position is not easy, because the engine cover must be raised to access the reset button. The acceleration or deceleration limit value ball detector according to the invention aims to remedy these drawbacks. This ball detector, as characterized in the claims, solves the problem of creating a detector which automatically triggers the hazard lights in particular in the event of an impact, but also in the event of a total or partial, fugitive reversal or reversal. or permanent, which can occur at reduced speed and without shock.
Le détecteur à bille, est constitué essentiellement d'un corps, conducteur de l'électricité, comportant en son milieu un évidemment tronconique, prolongé vers le bas par un puits de profondeur réglable dans lequel est logée une bille métallique, d'un couvercle, séparé du corps par une rondelle isolante, et d'un circuit comportant un relai contacteur dont la mise sous tension est commandée par la mise en contact de la bille métallique avec le couvercle et dont la mise hors tension est obtenue par action sur un bouton poussoir normalement fermé.The ball detector, essentially consists of a body, conductor of electricity, comprising in its middle a frustoconical recess, extended downwards by a well of adjustable depth in which is housed a metal ball, a cover, separated from the body by an insulating washer, and from a circuit comprising a contactor relay, the power up of which is controlled by bringing the metal ball into contact with the cover and the power off of which is obtained by action on a push button normally closed.
Le réglage de la profondeur du puits est obtenue par l'intermédiaire d'une vis étanche sur laquelle repose la bille métallique. L'action sur la vis étanche de réglage de profondeur du puits détermine une cote a, qui, suivant l'angle d'assiette du véhicule, fixe la valeur limite d'accélération ou de décélération.The depth adjustment of the well is obtained by means of a tight screw on which the metal ball rests. The action on the tight screw for adjusting the depth of the well determines a dimension a, which, depending on the attitude angle of the vehicle, fixes the limit value of acceleration or deceleration.
Le corps peut-être incliné , selon un angle et dans un sens déterminé, afin de différencier la valeur limite d'accélération de la valeur limite de décélération. Selon un mode de réalisation,le couvercle est constitué d'une plaque isolante munie de deux pistes étamées circulaires conductrices concentriques, dont l'une est située au centre et reliée à un plot de contact, et dont l'autre, pincée entre la plaque isolante et le corps, est reliée à un autre plot de contact.The body can be tilted, at an angle and in a determined direction, in order to differentiate the acceleration limit value from the deceleration limit value. According to one embodiment, the cover consists of an insulating plate provided with two concentric conductive circular tinned tracks, one of which is located in the center and connected to a contact pad, and the other of which, clamped between the plate insulator and the body, is connected to another contact pad.
Les avantages obtenus grâce à cette invention consistent essentiellement en ce que les feux de détresse fonctionnent automatiquement en cas de retournement ou de renversement total ou partiel, fugitif ou permanent, pouvant survenir à vitesse réduite et sans choc, et, ceci,grâce au réglage du seuil de déclenchement qui est multidirectionnel. Ce détecteur est insensible à des chocs dont la direction est perpendiculaire au plan de déplacement: sauf si ceux ci sont accompagnés d'une décélération correspondant à celle déterminée par la pente de l'évidement tronconique, et est étanche aux agressions du milieu extérieur. De plus, les fonctions du dit véhicule telles que mise en marche de feux de détresse, indicateur de changement de direction ne sont pas altérées. D'autres caractéristiques et avantages apparaîtront dans la description qui va suivre de deux mσdes de réalisation du détecteur à bille, selon l'invention, donnés à titre d'exemples non limitatifs, au regard des dessins annexés sur lesquels :The advantages obtained thanks to this invention consist essentially in the fact that the hazard warning lights operate automatically in the event of total or partial reversal or reversal, fugitive or permanent, which may occur at reduced speed and without shock, and this, thanks to the adjustment of the trigger threshold which is multidirectional. This detector is insensitive to shocks the direction of which is perpendicular to the plane of movement: unless these are accompanied by a deceleration corresponding to that determined by the slope of the frustoconical recess, and is impervious to attack by the external environment. In addition, the functions of said vehicle such as switching on hazard lights, direction change indicator are not impaired. Other characteristics and advantages will appear in the following description of two embodiments of the ball detector according to the invention, given by way of nonlimiting examples, with regard to the appended drawings in which:

Vu sa conception, qui permet le déclenchement des feux de détresse pour n'importe quel choc multirectionnel supérieur à l'intensité du seuil de déclenchement, le détecteur à bille selon l'invention peut-être disposé dans n'importe quel sens axial du dit véhicule, sensiblement horizontal.Two contacts are arranged respectively on the body 1 and the cover 6. Given its design, which allows the triggering of the hazard warning lights for any multi-directional shock greater than the intensity of the triggering threshold, the ball detector according to the invention may be arranged in any axial direction of said vehicle, substantially horizontal.
L'ensemble détecteur à bille A et circuit à relier aux différents organes électriques du véhicule est délimité par le trait mixte 23. Le circuit existant sur le véhicule comporte l'interrupteur d'allumage à la clé 22, un interrupteur 9 pour la mise en fonction manuelle des feux de détresse, lequel peut-être aussi utilisé, selon un mode de montage préférentiel, comme interrupteur de mise hors circuit du fonctionnement des feux de détresse, constitués des feux d'indicateur de direction gauche 17 et de direction droit 18. Les feux d'indicateurs de direction gauche 17- et droit 18 sont reliés par l'intermédiaire de relais contacteur à une centrale de clignotant 21.The assembly of ball detector A and circuit to be connected to the various electrical components of the vehicle is delimited by the dashed line 23. The existing circuit on the vehicle comprises the ignition switch with the key 22, a switch 9 for setting manual function of the hazard warning lights, which can also be used, according to a preferred mounting mode, as a switch for switching off the operation of the hazard warning lights, made up of the left direction indicator 17 and right direction indicator lights 18. The left-hand 17 and right-hand direction indicator lights 18 are connected via a contactor relay to a turn signal unit 21.
Des voyants témoins 19 et 20 signalent respectivement au conducteur la mise en fonctionnement des feux de détresse et la mise en commun des feux d'indication de direction gauche 17 et de direction droit 18. Le schéma électrique de montage, représenté à la figure 4 , se trouve à l'état de repos. Lors d'un choc ou d'un retournement, ou d'un renversement total ou partiel, fugitif ou permanent, pouvant survenir à vitesse réduite et sans choc, la bille 4, dés que l'intensité de ce choc ou de ce renversèment est supérieure à celle du seuil de déclenchement, quitte le puits 2 et monte le long de la pente de l' évidement tronconique conducteur jusqu'à faire contact momentanément entre le corps 1 et le couvercle 6. Le contact crée instantanément un courant électrique et une force électromagnétique qui agit simultanément, d'une part sur un relai contacteur 8, dont le rôle est de fermer le circuit d'auto-alimentation, et, d'autrepart, sur des relais contacteurs permettant : la mise hors circuit du faisceau électrique par ouverture du contact 8 a, afin d'éviter tout risque d'incendie, l'alimentation de la centrale de clignotant 21 d'origine, l'alimentation des feux d'indication de direction gauche 17 et de direction droite 18, ainsi que l'alimentation des voyants témoins 19 et 20. Le fonctionnement des feux de détresse peut-être interrompu par action sur un interrupteur 9 situé près du tableur de bord. Le circuit d'auto-alimentation étant ouvert, il ne permet plus la fermeture des autres relais contacteurs,vu que la force électromagnétique est interrompue par la mise en hors circuit du circuit d'auto-alimentation. Selon un autre mode de réalisation simplifié, en vue de son industrialisation, le détecteur à bille selon l'invention, comprend,comme nous le montre les figures 2 et 3, un couvercle constitué d'une plaque isolante 10, munie de deux pistes étamées circulaires, conductrices concentriques 10 a et 10 b. Le corps 11 est en laiton embouti ou repoussé. La piste étamée 10 a est située au centre et est reliée à un plot de contact 14 et l'autre 10 b , pincée entre la. plaque isolante 10 et le corps 11, est reliée à un plot de contact 15. La profondeur du puits 16 est ajustable par une vis étanche 13.Warning lights 19 and 20 respectively signal the driver when the hazard warning lights are on and when the left direction indicator 17 and right direction indicator lights are shared 18. The electrical circuit diagram, shown in FIG. 4, is in the resting state. During a shock or a reversal, or a total or partial reversal, fugitive or permanent, which can occur at reduced speed and without shock, the ball 4, as soon as the intensity of this shock or this reversal is higher than that of the triggering threshold, leaves the well 2 and rises along the slope of the frustoconical conductive recess until making temporary contact between the body 1 and the cover 6. The contact instantly creates an electric current and a force electromagnetic which acts simultaneously, on the one hand on a contactor relay 8, whose role is to close the self-supply circuit, and, on the other hand, on contactor relays allowing: the switching off of the electric harness by opening of contact 8 a, in order to avoid any risk of fire, supply to the original indicator central 21, supply to the left direction indicator 17 and right direction indicator lights 18, as well as the power of the witness lights oins 19 and 20. The operation of the hazard warning lights may be interrupted by action on a switch 9 located near the dashboard. The self-supply circuit being open, it no longer allows the closing of the other contactor relays, since the electromagnetic force is interrupted by switching off the self-supply circuit. According to another simplified embodiment, with a view to its industrialization, the ball detector according to the invention comprises, as shown in FIGS. 2 and 3, a cover consisting of an insulating plate 10, provided with two tinned tracks circular, concentric conductors 10 a and 10 b. The body 11 is made of stamped or spun brass. The tinned track 10 a is located in the center and is connected to a contact pad 14 and the other 10 b, pinched between the. insulating plate 10 and the body 11, is connected to a contact pad 15. The depth of the well 16 is adjustable by a tight screw 13.
Lors d'un choc, d'un retournement total ou partiel, fugitif ou permanent, pouvant survenir à vitesse réduite et sans choc, la bille 4, en contact avec les pistes étamées, circulaires, conductrices 10 a et 10 b, permet instantanément l'enclenchement de la mise en fonctionnement des feux de détresse, suivant le même principe de fonctionnement que celui représenté à la figure 4. Le détecteur à bille de valeur limite d'accélération ou de décélération est plus particulièrement applicable dans le domaine de la construction automobile, mais peut-être utilisé comme un moyen de détection des accélérations ou décélérations anormales subiαspar un matériel délicat lors de son transport. During a shock, a total or partial reversal, fugitive or permanent, which may occur at reduced speed and without shock, the ball 4, in contact with the tinned, circular, conductive tracks 10 a and 10 b, instantly allows the activation of the hazard warning lights, following the same operating principle as that shown in FIG. 4. The ball detector for acceleration or deceleration limit value is more particularly applicable in the field of automobile construction , but can be used as a means of detecting abnormal accelerations or decelerations undergone by delicate material during transport.
