Abstract

The object of this invention is to protect any vehicle against theft by virtue of an electronic detection device and electromechanical and mechanical protection. The latter is ensured by non-return valves inserted in the braking or other circuit. If the key 13 is removed: anti-theft position, the slightest break-in triggers the electronic detection alarm 57 which then powers the solenoid valve 53 thus allowing the oleopneumatic accumulator 54 to discharge into the pipelines 55 and 52 and into the block 1 which comprises an additional seat (orifice 66) relating to one of the valves, in order finally to come to lock the brakes 32 by one of the pipelines 31. It is sufficient to turn the key 13 of the anti-theft device in order to reestablish the normal circuit and thus shut off the non-return valves. The device according to the addition to the main patent is particularly intended to block any vehicle in situ on the slightest break-in.

Description

La présente demande concerne un certificat d'addition à la demande de brevet
principal n0 84 05 345, déposé le 5 avril 1984, qui avait pour objet un : DISPOSITIF
ANTIVOL POUR VEHICULES PAR NEUTRALISATION DU CIRCUIT GLECTRIQUE
ET PAR BLOCAGE DES FREINS APRES SOLLICITATION qui comportait une serrure à barillet assurant la commande du déplacement d'au moins un clapet dans le circuit de freinage après mise en oeuvre du dispositif.The present application concerns a certificate of addition to the patent application
principal n0 84 05 345, filed on April 5, 1984, which had as its object:
ANTITHEFT FOR VEHICLES BY NEUTRALIZATION OF THE ELECTRICAL CIRCUIT
AND BY LOCKING THE BRAKES AFTER SOLICITATION which included a cylinder lock ensuring the control of the movement of at least one valve in the braking circuit after implementation of the device.

Ce dispositif antivol est constitué par un bloc comportant un tiroir déplaFable où sont incorporés des clapets; des rainures de circulation dans le tiroir mettent en communication l'entrée et la sortie de l'appareil sur le circuit hydraulique et /ou pneumatique du véhicule. Ce tiroir est rotatif ou linéaire et est commandépar une serrure par des moyens d'accouplement apprpriés et des moyens d'indéxage pour une position de travaii (vol) et une position de repos (route). This anti-theft device consists of a block comprising a movable drawer into which valves are incorporated; circulation grooves in the drawer connect the inlet and outlet of the device to the hydraulic and / or pneumatic circuit of the vehicle. This drawer is rotary or linear and is controlled by a lock by appropriate coupling means and indexing means for a working position (flight) and a rest position (road).

Un contacteur électrique solidaire du bloc, commandé par le tiroir permet à l'indexage de couper ou d'alimenter les différents circuits électriques du véhicule. An electrical contactor integral with the block, controlled by the drawer allows the indexing to cut or supply the various electrical circuits of the vehicle.

L'appareil est monobloc, la serrure est en liaison complète avec cetui-ci. Les entrées et les sorties sont parallèles à l'axe de la serrure pour un encombrement réduit. The device is monobloc, the lock is in complete connection with this one. The inputs and outputs are parallel to the axis of the lock for a small footprint.

Des raccords cassants s'opposent au démontage du dispositif pour sa mise hors service. Brittle connections oppose the dismantling of the device for its decommissioning.


L'objet de la présente addition est d'apporter des perfectionnements augmentant les possibilités d'utilisation de l'antivol.
The object of the present addition is to provide improvements increasing the possibilities of using the anti-theft device.

Ce perfectionnement prévoit un système de blocage des freins en cas d'ouverture des portières ou bris de glaces du véhicule. This improvement provides for a brake locking system in the event of the doors being opened or the vehicle glass broken.

Ce système de blocage comporte une partie électrique ou électronique de détection d'effraction, une partie de commande électrique et enfin une partie de puissance oléo-pneumatique. Selon un mode préférentiel de réalisation, un second siège est usiné dans le bloc afin d'alimenter un accumulateur oléo-pneumatique qui provoque le blocage des freins au moyen d'une électrovanne à clapet (qui sert aussi à charger l'accumulateur) en cas de mise en action du dispositif de détection. This blocking system includes an electrical or electronic intrusion detection part, an electrical control part and finally an oleo-pneumatic power part. According to a preferred embodiment, a second seat is machined in the block in order to supply an oleo-pneumatic accumulator which causes the brakes to be blocked by means of a solenoid valve (which also serves to charge the accumulator) in the event of activation of the detection device.

Selon une première caractéristique de cet additif, le blocage instantané à toute effraction, s'effectue sur un seul circuit de freinage. L'autre circuit non modifié assure de toute façon le blocage, comme selon le brevet principal à la première sollicitation sur les freins. According to a first characteristic of this additive, instantaneous blocking against any break-in takes place on a single braking circuit. The other unmodified circuit ensures blocking anyway, as according to the main patent on the first request on the brakes.

Selon une caractéristique essentieile de sécurité, le véhicule n'est mis en marche qu'en position 'route' de la clef de l'antivol; toute autre position coupe électriquement l'allumage le démarreur et déclenche l'alarme par l'avertisseur sonore: le contacteur électrique de l'antivol n'étant plus alimenté. According to an essential safety characteristic, the vehicle is only started in the 'road' position of the anti-theft key; any other position electrically cuts the ignition on the starter and triggers the alarm by the horn: the electric anti-theft switch is no longer supplied.

Selon un résultat apporté par l'invention, aucun blocage intempestif n'est prévisible au vu du dispositif; I'antivol en lui-même est passif et les clapets s'effacent à la rotation de la clé pour laisser circuler librement l'huile des freins dans les rainures du tiroir prévues à cet effet. According to a result provided by the invention, no untimely blocking is foreseeable in view of the device; The anti-theft device itself is passive and the valves disappear when the key is rotated to allow the brake oil to circulate freely in the grooves in the drawer provided for this purpose.

Selon une autre caractéristique, la commande de l'electrovanne s'effectue grâce à un dispositif électronique qui assure la protection de l'habitacle et qui agit à-toute tentative d'effraction.  According to another characteristic, the solenoid valve is controlled by an electronic device which protects the passenger compartment and which acts upon any attempted break-in.

A titre d'illustration, des dessins sont joints qui représentent :
Figure 1 le schéma de principe du dispositif de blocage instantané des freins

Figure 2 and 3: sectional views of the distributor block of the improved device.

Les caractéristiques et avantages évidents de ce dispositif ressortiront de la description qui va suivre. Les dessins annexes sont donnés à titre indicatif, mais nullement limitatif quant à la réalisation finale. The obvious characteristics and advantages of this device will emerge from the description which follows. The annexed drawings are given as an indication, but in no way limitative as to the final realization.

Selon la Figure 1, représentant le schéma de principe de l'ensemble relié au circuit de freinage: le bloc (1) est connecté d'une part avec le maitre-cylindre par les tuyauteries;(30) et aux freins par les tuyauteries (32). According to Figure 1, representing the block diagram of the assembly connected to the braking circuit: the block (1) is connected on the one hand with the master cylinder by the pipes; (30) and to the brakes by the pipes ( 32).

Une tuyauterie (52) relie I'electrovanne à clapet (53) au bloc (1) et une autre tuyauterie < 55) relie cette électrovanne à clapet (53) à l'accumutateur oléopneumatique (54).  A pipe (52) connects the solenoid valve (53) to the block (1) and another pipe <55) connects this solenoid valve (53) to the oleopneumatic accumulator (54).

La Figure 2 est une vue en coupe du bloc (1k selon AA de la Figure 1, qui représente le tiroir (2) en position route , la bille (8) venant fermer le passage (66) vers l'électrovanne à clapet (53). Figure 2 is a sectional view of the block (1k along AA of Figure 1, which shows the slide (2) in the road position, the ball (8) closing the passage (66) to the solenoid valve (53 ).

La Figure 3 est une vue en coupe de bloc (1) en position antivol : la bille (8) vient sur son siège empêchant le retour de l'huile des freins vers le mar- trecylindre par l'orifice (67) et l'une des canaiisations (30). Figure 3 is a sectional view of block (1) in anti-theft position: the ball (8) comes on its seat preventing the return of the brake oil to the cylinder by the orifice (67) and the one of the pipes (30).

D'après les figures 1 et 2, lorsque la clé (13) est en position (I), ie contacteur électrique peut permettre le démarrage du véhicule (la coupure électrique de l'alarme), le circuit de freinage est normal :le flux et le reflux du liquide de frein sont autorisés. According to FIGS. 1 and 2, when the key (13) is in position (I), ie the electrical switch can allow the vehicle to start (the electric cut-off of the alarm), the braking circuit is normal: the flow and reflux of brake fluid are allowed.

Lorsque la clé (13) est en position (II) (Figures 1 et 3), le contacteur électrique coupe l'alimentation électrique du démarreur, de l'allumage et met en veille l'alarme. When the key (13) is in position (II) (Figures 1 and 3), the electrical switch cuts off the electrical supply to the starter, the ignition and puts the alarm on standby.

Le circuit de freinage grace au clapet anti-retour (8) réalise le blocage
Instantané entre le maitrecylindre (28) et le bloc (1) au niveau du siège de l'orifice (67). L'automobiliste quittant son véhicule, appuiera sur la pédale de frein (29) afin de charger l'accumulateur (54) via l'orifice (67) du bloc (1): la bille (8) se dégageant dans l'évidement (65) en comprimant le ressort, pour parvenir dans l'orifice (66) puis arriver par la conduite (52) à l'électrovanne à clapet (53) qui laisse le fluide dans ce sens et grace à la tuyauterie (55) va charger ledit accumulateur (54).The braking circuit thanks to the non-return valve (8) realizes the blocking
Snapshot between the master cylinder (28) and the block (1) at the level of the orifice seat (67). The motorist leaving his vehicle, will press the brake pedal (29) in order to charge the accumulator (54) via the orifice (67) of the block (1): the ball (8) disengaging in the recess ( 65) by compressing the spring, to reach the orifice (66) then arrive via the line (52) at the solenoid valve (53) which leaves the fluid in this direction and thanks to the piping (55) will charge said accumulator (54).

Un système électronique (57) pour la détection d'effraction alimente par fils (56) I'électrovanne (53) en cas de tentative de vol. Alors, I'électrovanne à clapet (53) laisse l'accumulateur (54) se décharger dans le circuit de freinage (31,32) et, de ce fait bloque un circuit de freinage. Le circuit (31,33) est alimenté lui au travers d'un autre clapet, décalé dans le tiroir et non représenté, relié à l'orifice (68) et (69). An electronic system (57) for burglary detection supplies by wire (56) the solenoid valve (53) in the event of attempted theft. Then, the valve solenoid valve (53) allows the accumulator (54) to discharge in the braking circuit (31,32) and, therefore, blocks a braking circuit. The circuit (31,33) is supplied to it through another valve, offset in the drawer and not shown, connected to the orifice (68) and (69).

II est évident que cet additif du dispositif peut être inséré dans le circuit hydraulique de l'embrayage et laissera ainsi l'embrayage débrayé.  It is obvious that this additive of the device can be inserted into the hydraulic circuit of the clutch and will thus leave the clutch disengaged.

En cas de fuite du liquide de freinage au niveau du maître-cylindre, si l'accumulateur est resté chargé, il pourrait éventuellement assurer le freinage du véhicule. Mais normalement, en position route, I'accumulateur -st toujours déchargé. In the event of brake fluid leaking from the master cylinder, if the accumulator remains charged, it could possibly brake the vehicle. But normally, in the road position, the accumulator is always discharged.

Le second circuit permet de bloquer les freins du véhicule assurant ainsi la fonction de frein à main, lorsque l'on charge l'accumulateur avant de quitter le véhicule. II suffit de tourner la clé en position route5 > pour rétablir le circuit de freinage normal, position (II).  The second circuit makes it possible to block the vehicle brakes, thus ensuring the handbrake function, when the battery is charged before leaving the vehicle. Just turn the key to the route5> position to restore the normal braking circuit, position (II).

Un contact électrique empêchent la mise en marche du véhicule si la clé (13) est dans une position autre que la position (I). ou (II).  An electrical contact prevents the vehicle from starting if the key (13) is in a position other than position (I). or (II).
