Abstract

The motor vehicle antitheft mechanism activates a steering lock or a break in the vehicle's electric circuit when the key is withdrawn from the lock. To prevent hazard arising from unwanted activation of the safety lock, the key is trapped in place to prevent withdrawal without an additional action by the driver. A lever (6) is pivoted on one side of the lock barrel (11) and passes below the key (2), fitting into a notch in the key profile. A spring (9) holds the lever in place to trap the key, and the lever is drawn clear of the key by a pull cable (12) operated by the driver when the key is to be withdrawn. A two handed action is thus required to withdraw. A two handed action is thus required to withdrawn the key reducing the risk of accidental withdrawal.

Description

L'invention concerne un antivol pour véhicule automobile du type comprenant une serrure à barillet actionnée par une clé et commandant au cours de sa rotation un pêne de verrouillage d'un organe essentiel à la marche du véhicule ainsi qu'un interrupteur électrique d'alimentation du véhicule, l'extraction de la clé commandant la libération du pêne de verrouillage. The invention relates to an anti-theft device for a motor vehicle of the type comprising a cylinder lock actuated by a key and controlling, during its rotation, a bolt for locking an organ essential to the operation of the vehicle as well as an electrical power switch of the vehicle, the extraction of the key controlling the release of the locking bolt.

Pour éviter le blocage intempestif ou accidentel du véhicule, qui se produirait si le verrouillage du pêne se produisait automatiquement lors du retour de la serrure à la position d'arrêt, on prévoit que ce verrouillage ne peut se produire qu'après une action délibérée de l'utilisateur, en général l'extraction de la clé. To avoid inadvertent or accidental blocking of the vehicle, which would occur if the bolt was locked automatically when the lock returned to the stopped position, it is provided that this locking can only occur after a deliberate action of the user, usually extracting the key.

On a exigé, pour accroître encore la sécurité, que l'action qui produit le verrouillage ne puisse avoir lieu que moteur arrêté, que l'utilisateur ait effectué une action mécanique additionnelle ne constituant pas une phase nécessaire de l'arrêt du moteur et qui ne puisse être effectuée simultanément avec l'arrêt du moteur d'une seule main. It was required, in order to further increase safety, that the action which produces the locking can only take place with the engine stopped, that the user has performed an additional mechanical action which does not constitute a necessary phase of the stopping of the engine and which cannot be performed simultaneously with stopping the engine with one hand.

On connaît des dispositifs mécaniques et électromécaniques agissant sur l'antivol pour interdire le passage de la serrure jusqu'à la position d'arrêt tant qu'une action mécanique n'a pas été exercée par la main de l'utilisateur autre que celle actionnant la clé. Ces dispositifs connus, qui permettent une action simultanée mais pas avec une seule main, sont donc conformes aux exigences précédentes. Cependant, is sont d'un prix de revient élevé et d'un encombrement accru. There are known mechanical and electromechanical devices acting on the anti-theft device to prevent the passage of the lock to the stop position as long as a mechanical action has not been exerted by the hand of the user other than that actuating the key. These known devices, which allow simultaneous action but not with one hand, therefore comply with the preceding requirements. However, they are of a high cost price and of an increased bulk.

La présente invention vise à répondre aux exigences précédentes grâce à un nouveau dispositif simple et économique du type précédent qui n'augmente pas l'encombrement de l'antivol. The present invention aims to meet the above requirements thanks to a new simple and economical device of the previous type which does not increase the size of the lock.

A cet effet, l'antivol selon l'invention est caractérisé par le fait qu'il comprend un levier pivotant commandé manuellement et rappelé élastiquement vers une position dans laquelle il coopère avec un épaulement de la clé pour interdire son extraction.  To this end, the anti-theft device according to the invention is characterized in that it comprises a pivoting lever controlled manually and resiliently returned to a position in which it cooperates with a shoulder of the key to prevent its extraction.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel
- la figure 1 est une vue schématique en élévation d'un antivol selon un exemple de réalisation de l'invention, monté sur la colonne de direction du véhicule;
- la figure 2 est une vue à plus grande échelle de l'antivol de la figure 1;
- la figure 3 est une vue en coupe selon la ligne
III-III de la figure 2;
- la figure 4 est une vue de dessus de l'antivol des figures 1 à 3;
- la figure 5 est une vue en élévation latérale d'un antivol selon une variante de l'invention;
- la figure 6 est une vue en coupe selon la ligne VI
VI de la figure 5; et
- la figure 7 est une vue schématique analogue à celle de la figure 6, pour une variante.The invention will be clearly understood on reading the following description made with reference to the accompanying drawing in which
- Figure 1 is a schematic elevational view of an anti-theft device according to an exemplary embodiment of the invention, mounted on the steering column of the vehicle;
- Figure 2 is an enlarged view of the lock of Figure 1;
- Figure 3 is a sectional view along the line
III-III of Figure 2;
- Figure 4 is a top view of the lock of Figures 1 to 3;
- Figure 5 is a side elevational view of an anti-theft device according to a variant of the invention;
- Figure 6 is a sectional view along line VI
VI of Figure 5; and
- Figure 7 is a schematic view similar to that of Figure 6, for a variant.

On se réfère tout d'abord aux figures 1 à 4. L'antivol 1, commandé par une clé 2, est monté sur la colonne de direction 3. L'extraction de la clé 2 hors du barillet 4 de la serrure de l'antivol 1 produit la libération du pêne de verrouillage (non représenté) de l'arbre de direction 5. We first refer to Figures 1 to 4. The lock 1, controlled by a key 2, is mounted on the steering column 3. The extraction of the key 2 out of the barrel 4 of the lock of the anti-theft device 1 releases the locking bolt (not shown) from the steering shaft 5.

Conformément à l'invention, l'antivol comprend un levier 6 solidaire d'une tige 7 articulée en 8 sur l'antivol 1 et rappelée par un ressort 9 vers une position de repos (représentée au dessin) dans laquelle le levier 6 vient recouvrir partiellement le barillet 4 et le canal de clé en coopérant avec un épaulement 10 de la clé de manière à interdire-son extraction. Un cache 11 recouvre partiellement le levier 6 pour interdire son actionnement par l'utilisateur avec la main qui actionne la clé 2. Une rotation de la tige dans la direction F, contre l'action du ressort 9, produit une rotation du levier dans la direction F', ce qui libère la clé 2 et permet son extraction. La longueur de la tige 7 et sa position sont telles que son actionnement ne peut être fait que par la seconde main du conducteur, éventuellement par son genou.  According to the invention, the anti-theft device comprises a lever 6 secured to a rod 7 articulated at 8 on the anti-theft device 1 and returned by a spring 9 to a rest position (shown in the drawing) in which the lever 6 comes to cover partially the barrel 4 and the key channel by cooperating with a shoulder 10 of the key so as to prevent its extraction. A cover 11 partially covers the lever 6 to prevent its actuation by the user with the hand which actuates the key 2. A rotation of the rod in the direction F, against the action of the spring 9, produces a rotation of the lever in the direction F ', which frees the key 2 and allows its extraction. The length of the rod 7 and its position are such that its actuation can only be done by the driver's second hand, possibly by his knee.

Dans la variante des figures 5 et 6, la tige 7 est remplacée par un cordon 12, le ressort 9 agissant directement sur le levier 6. Dans la forme de la figure 7, le cordon 12 est remplacé par un câble 13 logé dans une gaine et terminé par une tirette 14 fixée au tableau de bord. In the variant of FIGS. 5 and 6, the rod 7 is replaced by a cord 12, the spring 9 acting directly on the lever 6. In the form of FIG. 7, the cord 12 is replaced by a cable 13 housed in a sheath and finished with a pull tab 14 fixed to the dashboard.

Dans tous les cas, le levier 6 peut être en acier doux et être commandé par un électro-aimant (non représenté).  In all cases, the lever 6 can be made of mild steel and be controlled by an electromagnet (not shown).
