Abstract

The steering wheel is attached to the steering shaft at (M). It turns the lower shaft through the threaded nut (A) which is locked to the coupling (2), whose studs (T) engage the slots (4) in the sliding sleeve (3) which has internal splines (5) engaging the toothed wheel (6) at the head of the lower steering shaft (1b).The sleeve (3) is held in engagement by the spring (7) which acts on the inner face of the sleeve and the face of the toothed wheel (6). The lower shaft (1b) carries a journal (B) held in place by the threaded coupling (2) which prevents disconnection of the upper and lower shafts (1a,1b). The coupling (2) is held into the sleeve (3) by the sleeve (10) brazed into the outer sleeve at (S). The steering is disabled by pulling the knob (14) upwards, thus moving the sleeve assembly until the bolt (D), controlled by the key drops into the slot (15), and the coupling is disengaged at the faces (5,6).

Description

La présente invention concerne un dispositif destiné à rendre impossible la conduite d'un véhicule automobile s'il est équipé d'un volant de direction, et plus particulièrement des dispositifs interdisant l'action sur les roues au moyen d'un volant. The present invention relates to a device intended to make it impossible to drive a motor vehicle if it is equipped with a steering wheel, and more particularly to devices preventing action on the wheels by means of a steering wheel.

Des dispositifs de ce type general existent selon de nombreuses réalisations différentes qui peuvent être utilisées pour eeeêcher l'action sur les roues. Une caracteristigue commune à la plupart des dispositifs oonnus est le blocage de la tige de direction. Cette disposition présente certains avantages, mais également un inconvénient, en ce sens qu'en for çant sur le volant, on peut, sinon parvenir à autoriser la conduite du véhicule, endommager la colonne de direction. Devices of this general type exist in many different embodiments which can be used to prevent action on the wheels. A characteristic common to most of the known devices is the blocking of the steering rod. This arrangement has certain advantages, but also a disadvantage, in that by forcing the steering wheel, it can, if not succeed in authorizing the driving of the vehicle, damage the steering column.

Dans le dispositif antivol selon l'invention, une action aussi brutale soit-elle pour forcer le volant ne servirait à rien et ne nuirait à aucune partie de la ligne de direction, puisque le volant tourne fou lorsqu'il est en position d'interdiction de conduite. Par ailleurs, aucune pièce n'est accessible de ltextérieur étant donné que tout I'ensegble est placé dans la colonne de direction. Une autre caractéristique commune à certains dispositifs antivol est également que le volant tourne fou et de ce fait n'oriente pas les roues, cette disposition pressente aussi certains avantages, mais également un inconvénient, en ce sens qu'il faut changer le volant et que de ce fait, le véhicule ne peut être équipé d'un air bag. In the anti-theft device according to the invention, an action as brutal as it is to force the steering wheel would be useless and would not harm any part of the line of direction, since the steering wheel turns mad when it is in the prohibited position driving. Furthermore, no room is accessible from the inside since the whole set is placed in the steering column. Another characteristic common to certain anti-theft devices is also that the steering wheel turns crazy and therefore does not orient the wheels, this arrangement also has certain advantages, but also a disadvantage, in that it is necessary to change the steering wheel and that therefore, the vehicle cannot be equipped with an air bag.

Dans le dispositif selon l'invention, rien n' eeech e la mise en plaoe d'un volant air bag. Ces avantages ainsi que d'autres sont obtenus en réalisant le dispositif selon l'invention, d'après les revendications annexées. In the device according to the invention, nothing speaks the setting up of an air bag steering wheel. These advantages as well as others are obtained by producing the device according to the invention, according to the appended claims.

Un exemple de réalisation du dispositif antivol selon l'invention est représenté sur les dessins annexés et sera décrit plus en détail ci-après. An exemplary embodiment of the anti-theft device according to the invention is shown in the accompanying drawings and will be described in more detail below.

La figure 1 planche 1/2 montre une coupe longitudinale du dispositif selon l'invention en position d'orientation possible des roues. Figure 1 plate 1/2 shows a longitudinal section of the device according to the invention in the possible orientation position of the wheels.

La figure t planche 2/2 montre le détail de la partie coulissante (douille coulissante, manchon coulissant) sur la coupelle d'entrainaBent taraudée. Figure t plate 2/2 shows the detail of the sliding part (sliding sleeve, sliding sleeve) on the threaded drive cup.

La figure 3 planche 2/2 montre le détail de montage de la gâchette de degagement de la partie coulissante. Figure 3 plate 2/2 shows the mounting detail of the trigger for release of the sliding part.

En référence à ces dessins, le dispositif antivol représenté comporte une colonne de direction 11 équipée pour la mise en place d'un dispositif de direction C dont il vient modifier l'action. Par ailleurs, la dite colonne de direction reçoit tout l'assemblage décrit ci-dessous et en assure ainsi la protection.  With reference to these drawings, the anti-theft device shown comprises a steering column 11 equipped for the installation of a steering device C, the action of which it changes. In addition, said steering column receives the entire assembly described below and thus provides protection.

En position d'oriention des roues, le volant fixé en N sur la tige de direction supérieure la entraîne celle-ci et, par son bossage fileté A, la coupelle d'entraînement taraudée 2 dans laquelle il est vissé, pour agir par les tétons T de cette dernière sur la douille coulissante 3, par I'in terédiaire des lumières 4 de cette douille coulissante, laquelle est munie de cannelures intérieures 5 gui agissent sur un engrenage 6 solidaire de la tige de direction inférieure lb gui est entraînée à son tour, permettant ainsi une action sur l'orientation des roues du véhicule, ce gui autorise sa conduite. In the wheel orientation position, the steering wheel fixed at N on the upper steering rod drives it and, by its threaded boss A, the threaded drive cup 2 into which it is screwed, to act by the pins T of the latter on the sliding bush 3, by means of the lights 4 of this sliding bush, which is provided with internal grooves 5 which act on a gear 6 secured to the lower steering rod lb which is in turn driven , thus allowing an action on the orientation of the vehicle wheels, this mistletoe authorizes its driving.

La douille coulissante 3 est maintenue dans cette position avant, par un ressort 7 gui prend appui d'une part, sur l'engrenage 6, et d'autre part sur un rebord de la douille coulissante. The sliding sleeve 3 is held in this front position, by a spring 7 which is supported on the one hand, on the gear 6, and on the other hand on a flange of the sliding sleeve.

la tige de direction inférieure Ib est munie d'un tourillon B maintenu par un rebord de la coupelle d'entLînement taraudée 2 gui empe^cbe la désolidarisation des tiges de direction la et lb tout en assurant le maintien de leur alignent sans jeu, par serrage du bossage fileté A de la tige de direction supérieure la dans la coupelle d'entraînement taraudée 2 soit directenent, soit par l'intennédiaire d'une rondelle Belleville 8 gui prend appui sur la face arrière du tourillon B Une vis de blocage 9 vient maintenir le bossage B en position de serrage suffisant pour assurer la rotation libre du volant en position antivol. the lower steering rod Ib is provided with a trunnion B held by a rim of the tapped entLîcement cup 2 which empe ^ cbe the separation of the steering rods la and lb while ensuring the maintenance of their align without play, by tightening of the threaded boss A of the upper steering rod la in the threaded drive cup 2 either directly or by means of a Belleville washer 8 which rests on the rear face of the journal B A locking screw 9 comes keep boss B in the tightening position sufficient to ensure free rotation of the steering wheel in the anti-theft position.

La coupelle d'entraînement taraudée 2 est maintenue prisonnière dans la douille coulissante 3 par un manchon coulissant 10 soudé sur la dite douille coulissante en S. The tapped drive cup 2 is held captive in the sliding sleeve 3 by a sliding sleeve 10 welded to said sliding S-shaped sleeve.

Lorsque le conducteur voudra en emçE^cher l'usage, il tirera en arrière la gâchette 14 qui entraînera dans son mouvement l'ensemble douille coulissante-manchon coulissant jusqu'à la butée arrière et il actionnera la clef du dispositif à blocage de direction C dont le doigt D ne bloquera pas la direction, mais retiendra l'ensemble douille coulissante-manchon coulissant en arrière en se logeant dans la gorge 15 du manchon coulissant 10.La volant entraidera alors la tige de direction supérieure la centrée par le roulement à billes 12 et son bossage fileté
A, la coupelle d'entrainement 2 qui tournera autour du tourillon B, la douille coulissante 3 et le manchon coulissant 10, sans entraîneur l'engre- nage 6 ni la tige de direction inférieure Ib centrée sur le roulement à billes 13 rendant ainsi toute conduite du véhicule impossible. When the driver wants to use it, he will pull back the trigger 14 which will cause the sliding bushing-sliding sleeve assembly to move as far as the rear stop and he will actuate the key to the direction blocking device C whose finger D will not block the direction, but will retain the sliding bushing-sliding sleeve assembly back while being housed in the groove 15 of the sliding sleeve 10.The flywheel will then help the upper steering rod centered by the ball bearing 12 and its threaded boss
A, the drive cup 2 which will rotate around the pin B, the sliding sleeve 3 and the sliding sleeve 10, without driving the gear 6 or the lower steering rod Ib centered on the ball bearing 13 thus making all vehicle driving impossible.

Selon une variante non illustrée, il est possible de prévoir un systèse de blocage en position avant de la douille coulissante que l'on dévérouillerait en agissant sur la gâchette. According to a variant not illustrated, it is possible to provide a locking system in the front position of the sliding sleeve which would be unlocked by acting on the trigger.

Le dispositif selon l'invention est particulièrement destiné à servir d'antivol sur les voitures légères et sur les poids lourds.  The device according to the invention is particularly intended to serve as an anti-theft device on light cars and on heavy goods vehicles.
