Abstract

Cette invention a pour but de protéger contre le vol tout véhicule grâce à une protection électronique de détection (57) et électromécanique (53), (54) et (1). Cette protection mécanique est assurée par des clapets anti-retour insérés ou non dans le circuit de freinage. Si la clé (13) est enlevée: position antivol; la moindre effraction déclenche l'alarme électronique de détection (57) qui alimente l'électrovanne à clapet (53) laissant ainsi l'accumulateur oléopneumatique (54) se décharger dans les tuyauteries (55) et (52) et le bloc (1) pour venir enfin bloquer les freins (33) par les tuyauteries (31). Il suffit de tourner la clé (13) de l'antivol pour rétablir le circuit normal et ainsi effacer les clapets anti-retour. Ce dispositif selon l'additif au brevet principal est particulièrement destiné à bloquer sur place tout véhicule à la moindre effraction.The object of this invention is to protect any vehicle against theft by means of electronic detection (57) and electromechanical (53), (54) and (1) protection. This mechanical protection is ensured by non-return valves inserted or not in the braking circuit. If the key (13) is removed: anti-theft position; the slightest break-in triggers the electronic detection alarm (57) which powers the solenoid valve (53) thus letting the oleopneumatic accumulator (54) discharge in the pipes (55) and (52) and the block (1) to finally block the brakes (33) by the pipes (31). Just turn the key (13) of the anti-theft device to restore the normal circuit and thus erase the non-return valves. This device according to the addendum to the main patent is particularly intended to block on the spot any vehicle at the slightest break-in.

Description

DISPOSITIF ANTIVOL POUR VÉHICULES : PAR NEUTRALISATION DU CIRCUIT ÉLECTRIQUE ET PAR BLOCAGE DES FREINS APRES SOLLICITATION. ANTITHEFT DEVICE FOR VEHICLES: BY NEUTRALIZATION OF THE ELECTRICAL CIRCUIT AND BY LOCKING THE BRAKES AFTER SOLICITATION.
Le dispositif selon l'invention a pour but de protéger contre le vol tout véhicule grâce à une protection électrique et mécanique.The purpose of the device according to the invention is to protect any vehicle against theft by means of electrical and mechanical protection.
Dans ce domaine, des dispositifs sont connus dans lesquels des contacteurs électriques et des systèmes électroniques avertissent de l'effraction at empêchent le démarrage éventuel du véhicule.In this field, devices are known in which electrical contactors and electronic systems warn of break-in and prevent the possible starting of the vehicle.
La protection mécanique complète alors la protection électrique du fait que cette der¬ nière peut être neutralisée éventuellement par une personne avertie. Cette protection est assurée par des clapets anti-retour montés en série dans le circuit de freinage. Lors de l'utilisation πon- autorisée du véhicule, même si le circuit électrique est rétabli, à la première sollicitation des freins le véhicule restera définitivement bloqué sur place; seule la rotation de la clé de commande pourra libérer le blocage des freins.The mechanical protection then supplements the electrical protection because this latter can possibly be neutralized by an informed person. This protection is ensured by non-return valves mounted in series in the braking circuit. During the πon- authorized use of the vehicle, even if the electrical circuit is restored, at the first request of the brakes the vehicle will remain permanently blocked on site; only the rotation of the control key can release the brake lock.
Les problèmes qui peuvent résulter de tels dispositifs sont :The problems that can result from such devices are:
- blocage intempestif des freins dû à une rotation insuffisante de la clé lors d'unfreinage :le chemin du liquide de frein étant tel qu'il passe toujours au travers du clapet et donc de la bille.- untimely blocking of the brakes due to insufficient rotation of the key during braking: the path of the brake fluid being such that it always passes through the valve and therefore the ball.
- du fait que les réalisations proposées utilisent des poussoirs qui viennent en appui sur les billes des clapets, lesdits poussoirs sont actionnés par un excentrique par l'intermédiaire d'un axe fileté sur le support des poussoirs. Cet empilage de pièces en mouvement oblige à resserer les tolérances de fonctionnement idéal qui sont difficiles à respecter.- The fact that the proposed embodiments use pushers which come to bear on the balls of the valves, said pushers are actuated by an eccentric by means of a threaded axis on the support of the pushers. This stacking of moving parts means tightening the ideal operating tolerances which are difficult to meet.
- étanchéité défaillante : à cause des nombreuses pièces rapportées susceptibles de fuir; à cause aussi des poussoirs qui ne sont guidés que par des joints et qui sont montés flottants de part e* d' autre d'une fourchette poussée axialement ce qui entrafne une détérioration rapide des joints.- faulty sealing: because of the numerous attachments likely to leak; also because of the pushers which are guided only by joints and which are mounted floating on either e * else an axially thrust fork which entrafne rapid deterioration of the seals.
- dureté de la clé:dûe à la force appliquée au poussoir pour vaincre la pression hydraulique de freinage s'appliquant sur la face opposée de la bille du clapet surtout dans le cas où le circuit de freinage a été mis en position de blocage par un appui préalable sur la pédale de frein après rotation de la clé pour mise en position antivol.- hardness of the key: due to the force applied to the plunger to overcome the hydraulic braking pressure applied on the opposite face of the valve ball, especially in the case where the braking circuit has been put in the blocking position by a press the brake pedal beforehand after turning the key to set the anti-theft position.
- commande indirecte des poussoirs d'où une usure des pièces de commande : excentrique, pêne, poussoirs ...- indirect control of the pushers, resulting in wear of the control parts: eccentric, bolt, pushers, etc.
- aucun arrêt des pièces en butée, les pièces de commande- sont liées par des filetages sans serrage effectif de celles-ci.- no stop of the parts in abutment, the control parts - are linked by threads without effective tightening thereof.
- enfin des pocnes d'air peuvent subsister à l'intérieur et sont difficilement éliminées.- finally air pockets can remain inside and are difficult to remove.
L'objet de l'invention est de fournir un dispositif permettant de résoudre ces problèmes et qui présente par ailleurs d'autres avantages :The object of the invention is to provide a device making it possible to solve these problems and which also has other advantages:
Ce dispositif comprend d'une manière connue en soi : une serrure à barillet assurant la commande du déplacement d'au moins un clapet d'un circuit hydraulique et/ou pneumatique de frei¬ nage du véhicules après mise en oeuvre du dispositif, associé ou non à un double contacteur électrique ••ouvert-fermé^ assurant une protection sur le circuit de commande du dérr.arreur et de l'allumage ainsi que la mise en veille d'une alarme.This device comprises, in a manner known per se: a cylinder lock ensuring the movement of at least one valve of a hydraulic and / or pneumatic circuit for frei¬ swimming the vehicles after implementation of the device, associated or no to a double electric contactor •• open-closed ^ ensuring protection on the derr.arreur and ignition control circuit as well as putting an alarm on standby.
Selon une première caractéristique de l'invention, le système de commande des clapets est constitué d'un tiroir où sont incorporés lesdits clapets et une rainure de circulation du fluide mettant en relation rentrée et la sorties de l'appareil permettant ainsi d'éviter les blocages intempestifs causés par la rotation insuffisante de la# clé du fait que la bille n'est plus en vis-à-vis de son siège. Les - , .According to a first characteristic of the invention, the valve control system consists of a drawer in which said valves are incorporated and a groove for circulation of the fluid bringing the inlet and outlet of the device into relation, thereby avoiding inadvertent blockages caused by insufficient rotation of the key # because the ball is no longer in front of its seat. The -,.
Selon une autre caractéristique, les clapets sont constitués d'une bille disposée dans un logement radial du tiroir poussée par un ressort contenu dans ledit logement pour venir en appui sur son siège rapporté ou non solidaire du conduit d'entrée du bloc contenant le tiroir; l'étanchéité est assuré par des joints disposés de chaque coté de l'ensemble clapet-gorge montés dans le bloc, ou montés sur le tiroir.According to another characteristic, the valves consist of a ball disposed in a radial housing of the drawer pushed by a spring contained in said housing to come to bear on its seat, attached or not integral with the inlet duct of the block containing the drawer; sealing is ensured by seals arranged on each side of the valve-groove assembly mounted in the block, or mounted on the drawer.
Selon une autre caractéristique, le tiroir est pourvu de moyens d'iπdexage dans une position de travail (fonction antivol), et dans une ou plusieurs position de repos (position route) évitant ainsi tout risque de blocage intempestif causé par des vibrations ou une rotation insuffisante de la clé.According to another characteristic, the drawer is provided with iπdexing means in a working position (anti-theft function), and in one or more rest position (road position) thus avoiding any risk of untimely blocking caused by vibrations or rotation insufficient key.
Selon une autre caractéristique, de l'invention des logements recevant les ensembles ressort-bille sont reliés à la gorge de circulation par des conduits de fuite.According to another characteristic, of the invention of the housings receiving the ball spring assemblies are connected to the circulation groove by leakage conduits.
Selon un mode préférentiel de réalisation, le tiroir est rotatif et est relié par des moyens d'accouplement en rotation au barillet de la serrure et la rainure de circulation est constituée par une gorge disposée dans le plan transversal du clapet.According to a preferred embodiment, the drawer is rotary and is connected by means of coupling in rotation to the barrel of the lock and the circulation groove is constituted by a groove arranged in the transverse plane of the valve.
Selon un autre mode de réalisation le tiroir est linéaire, son déplacement s'effectue à Paide de deux plans inclinés maintenus en contact par un ressort, ou à l'aide d'jn système vis-écrou à partir d'une serrure disposée axialement. Cette commande en translation s'effectue par came ou excen¬ trique avec la serrure disposée perpendiculairement à l'axe du tiroir. Les clapets sont montés radiaiement et débouchent dans une rainure de circulation qui met en communication l'entrée et la sortie de l'antivol en position route. En position vol, la bille vient sur son siège,, ce qui entraîne le blocage des freins à la première sollicitation sur la pédale. Un indexage de position estaussi prévu (bille et cuvette par exemple). Dans tous les cas, la partie électrique ne pourra fonctionner que si la bille n'est plus sur son siège grâce à deux poussoirs coulissants en appui dans leurs cuvettes respectives, ou autres systèmes analogues.According to another embodiment, the drawer is linear, its movement is effected by means of two inclined planes kept in contact by a spring, or by means of a screw-nut system from a lock arranged axially. This translational control is effected by cam or excen¬ stick with the lock arranged perpendicular to the axis of the drawer. The valves are radially mounted and open into a circulation groove which connects the entry and exit of the anti-theft device in the road position. In the flight position, the ball comes to its seat, which causes the brakes to lock when the first action is taken on the pedal. Position indexing is also provided (ball and bowl for example). In all cases, the electrical part can only operate if the ball is no longer in its seat thanks to two sliding pushers resting in their respective bowls, or other similar systems.
Un limiteur de course est aussi prévu afin d'éviter de tourner indéfiniment le barillet et de positionner la clé aux positions route et vol.A stroke limiter is also provided in order to avoid turning the barrel indefinitely and to position the key in the road and flight positions.
La serrure sera bloquée axialement et en rotation par une bague et une goupille noyée dans le bloc contenant le tiroir, ou par d'autres moyens de blocage. Une seule pièce est en mouvement avec le barillet de la serrure. Tous les raccorde¬ ments s'effectuent directement sur le bfoc du dispositif.The lock will be locked axially and in rotation by a ring and a pin embedded in the block containing the drawer, or by other locking means. One piece is in movement with the barrel of the lock. All the connections are made directly on the bfoc of the device.
Une liaison de sécurité évitant toute mise hors service des circuits d'entrée au martre-cylindre et les circuits desortie en direction des freins est effectuée à l'aide de raccords pourvus d'une tête de manoeuvre <<cassaπte>) de sécurité par rupture au-delà d'un effort défini rendant ainsi l'ensemble indémontable.A safety binding avoiding deactivation of the input circuits to the marten cylinder and the output mechanism circuits towards the brakes is carried out using connectors provided with an operating head cassaπte <<>) security by rupture beyond a defined effort thus making the whole unassemblable.
Dans un trou taraudé du bloc, est fixé un fil électrique mis à la masse qui alimente le contacteur électrique-commandant l'allumage et l'alarme auxiliaire.In a tapped hole in the block, a grounded electrical wire is fixed which supplies the electrical contactor-controlling the ignition and the auxiliary alarm.
Cet appareil est prévu pour la commande d'un certain nombre d'organes avec le nombre de clapets correspondants.This device is intended for the control of a certain number of organs with the corresponding number of valves.
Les trous d'entrée et de sortie, peuvent être assymétrîques pour une construction plus réduite de l'appareil. Pour certaines utilisations, le dispositif peut être muni de sorties et d'entrées parallèles à l'axe du tiroir, le contacteur électrique est alors perpendiculaire à l'axe du tiroir. Cette invention peut équiper tous les véhicules, elle fonctionne aussi bien sur les freins hydrauliques, sur l'embrayage ou les freins de parking des poids lourds. Les caractéristiques principales et avantages évidents de ce dispositif ressortiront de la description qui va suivre; les dessins annexés sont donnés à titre indicatif mais nullement limita¬ tif quant à la réalisation finale.The inlet and outlet holes can be asymmetrical for a more reduced construction of the device. For certain uses, the device can be provided with outputs and inputs parallel to the axis of the drawer, the electrical contactor is then perpendicular to the axis of the drawer. This invention can equip all vehicles, it works equally well on hydraulic brakes, on the clutch or parking brakes of heavy goods vehicles. The main characteristics and obvious advantages of this device will emerge from the description which follows; the accompanying drawings are given as an indication but in no way limita¬ tive as to the final embodiment.

D'aprs le schéma de principe, figure 1 lorsque la clé (13) est en position (I), le contac¬ teur électrique peut permettre le démarrage du véhicule (ainsi que la coupure de l'alarme), le circuit de freinage est normal, c'est-à-dire que le flux et le reflux du liquide de frein sont autorisés.According to the block diagram, FIG. 1 when the key (13) is in position (I), the electric contactor can allow the vehicle to start (as well as the alarm cut-off), the braking circuit is normal, i.e. the ebb and flow of brake fluid is allowed.
Lorsque la clé (13) est en position (I I), le contacteur électrique coupe l'alimentation électrique du démarreur et de l'allumage et met en veille l'alarme. Les circuits de freinage (31 ) sont bloqués, la bille (8) est venue sur son siège, le flux sera autorisé et le reflux interdit, de ce fait le blocage des freins : position vol. II est évident que ce dispositif peut être inséré dans le circuit hydraulique de l'em- brayage qui laissera ainsi l'embrayage débrayé.When the key (13) is in position (II), the electrical switch cuts off the electrical supply to the starter and the ignition and puts the alarm on standby. The braking circuits (31) are blocked, the ball (8) has come to its seat, the flow will be authorized and the reflux prohibited, thereby blocking the brakes: flight position. It is obvious that this device can be inserted in the hydraulic circuit of the em- clutch which will leave the clutch disengaged.
Il suffit de tourner la clé en position route pour rétablir le circuit de freinage (positîon(l)).Simply turn the key to the road position to restore the braking circuit (position (l)).
L'étanchéité des différents circuits est assurée par des joints toriques compatibles avec le liquide des freins.The various circuits are sealed by O-rings compatible with the brake fluid.
Selon la figure 2, un poussoir cylindriqueM) coullissant axialement com¬ mande l'ouverture ou la fermeture du contacteur électrique (25) lors de la rotation de la clé (13) en position I ou II grâce à des cuvettes (48).According to Figure 2, a cylindrical pusherM) sliding axially commanding the opening or closing of the electrical contactor (25) during the rotation of the key (13) in position I or II by means of cups (48).
Fixé sur le barillet (14) de la serrure (5), un tenon cylindrique (3) est pourvu d'une partie (18) destinée à s'accoupler avec la partie complémentaire (19) usinée dans le tiroir rotatif (2). Une goupille (15) sert de butée sur la partie (18) du tenon, c'est elfe qui peut "définir la position du barillet de la serrure pour retirer la clé. Insérée dans le bloc (î) une goupille (15) limite la rotation du barillet en butant sur le tenon (3).Fixed on the barrel (14) of the lock (5), a cylindrical pin (3) is provided with a part (18) intended to couple with the complementary part (19) machined in the rotary drawer (2). A pin (15) serves as a stop on the part (18) of the post, it is elf who can " define the position of the barrel of the lock to remove the key. Inserted in the block (î) a pin (15) limit the rotation of the barrel abutting on the tenon (3).
Pour les poids lours, le freinage se fait par air comprimé, qu'un distributeur commande par l'intermédiaire de la pédale de frein. A la mise en route normale du véhicule de l'air comprimé est envoyé au frein de parking qui se libère. Le camion peut rouler. Le dispositif doit empêcher l'air d'arriver aux bouteilles d'air des freins de parking. Il suffit donc d'inverser les entrées avec les sorties du dispositif. For heavy weights, braking is done by compressed air, which a distributor controls via the brake pedal. When the vehicle is started normally, compressed air is sent to the parking brake, which is released. The truck can roll. The device must prevent air from reaching the parking brake air bottles. So just reverse the inputs with the outputs of the device.
