Abstract

The lock comprises a barrel lock which disables an essential element in the operation of the vehicle when the key is withdrawn. To prevent accidental withdrawal of the key, a plate is fitted over the face of the barrel to catch the key and lock it in place until deliberately released by a separate driver action. The plate (4) is pivoted (5) and drawn into the locking position by a spring (6) fixed to one end. To release the key (3), the plate is tilted clear of the key against the spring action. The tilting may be by a mechanical linkage or by a solenoid (13) actuated by a pushbutton (14). The plate is made of mild steel.

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 electric power switch of the vehicle, 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'auprès 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'd 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, ils 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 an increased size.

La présente invention vise à répondre aux exigences précédentes grâce a un nouveau dispositif simple et économique du type précédent qui n'augmente pas l'encombrement de l'antivol
A cet effet, l'antivol selon l'invention est caractérisé par le fait qu'il comprend un levier pivotant autour d'un axe fixe par rapport au corps de la serrure et rappelé élastiquement vers une position de repos, ledit levier présentant un profil coopérant sous l'action de moyens de rappel élastique avec un profil complémentaire du barillet ou d'un organe solidaire du barillet dans une position angulaire dudit barillet différente de la position d'extraction de la clé, ledit levier étant soumis à l'action d'un organe à commande manuelle assurant son pivotement contre l'action desdits moyens de rappel élastique. 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.
To this end, the anti-theft device according to the invention is characterized in that it comprises a lever pivoting about an axis fixed relative to the body of the lock and resiliently biased towards a rest position, said lever having a profile cooperating under the action of elastic return means with a complementary profile of the barrel or of a member integral with the barrel in an angular position of said barrel different from the extraction position of the key, said lever being subjected to the action of 'a manually controlled member ensuring its pivoting against the action of said elastic return means.

Les diverses variantes d'antivol comprennent un barillet 1 de serrure tourillonnant dans un corps 2 au moyen d'une clé 3, la rotation du barillet 1 commandant un pêne de verrouillage et un interrupteur électrique (non représentés)
Conformément à l'invention, un levier 4 est monté pivotant autour d'un axe 5 solidaire du corps de serrure 2 et rappelé par un ressort 6.The various anti-theft variants include a barrel 1 of a lock swiveling in a body 2 by means of a key 3, the rotation of the barrel 1 controlling a locking bolt and an electric switch (not shown)
According to the invention, a lever 4 is pivotally mounted about an axis 5 secured to the lock body 2 and returned by a spring 6.

Dans les òrmes de réalisation des figures 1 à 4, l'axe 5 est orthogonal à l'axe du barillet 1 et le levier 4 a la forme d'une palette entourant la tête 7 du barillet 1 au moyen d'une découpure circulaire 8 comportant une fenêtre radiale 9. La tête 7 comporte une saillie 10 dirigée vers
l'intérieur. Lorsque la saillie 10 n'est pas en regard de la fenêtre 9, le barillet 1 peut tourner librement au moyen de la clé 3, la saillie 10 glissant sur le levier 4 maintenu en appui par son ressort 6. Dès que la saillie 10 arrive en regard de la fenêtre 9, le levier 4 pivote sous l'action de son ressort 6 et la fenêtre 9 vient entourer la saillie 10, ce qui interdit la rotation du barillet. Cette position angulaire ne correspondant pas à l'extraction de la clé, le pêne commandé par la clé ne peut être libéré.In the embodiments of Figures 1 to 4, the axis 5 is orthogonal to the axis of the barrel 1 and the lever 4 has the shape of a pallet surrounding the head 7 of the barrel 1 by means of a circular cutout 8 having a radial window 9. The head 7 has a projection 10 directed towards
the interior. When the projection 10 is not facing the window 9, the barrel 1 can rotate freely by means of the key 3, the projection 10 sliding on the lever 4 held in abutment by its spring 6. As soon as the projection 10 arrives opposite the window 9, the lever 4 pivots under the action of its spring 6 and the window 9 surrounds the projection 10, which prevents rotation of the barrel. This angular position does not correspond to the extraction of the key, the bolt controlled by the key cannot be released.

Pour débloquer le barillet, un organe de commande est associé au levier 4. Dans le cas des figures 1 et 2, un câble 11 logé dans une gaine 11' et commandé par une tirette 12 permet de faire pivoter le levier 4 contre l'action de son ressort 6. Dans la variante des figures 3 et 4, le levier 4 est en acier doux et est soumis à l'action d'électro-aimants 13 reliés à une alimentation électrique par l'intermédiaire d'un interrupteur 14. L'actionnement de l'interrupteur 14 produit l'attraction du levier 4 et son pivotement contre l'action de son ressort 6. To unlock the barrel, a control member is associated with the lever 4. In the case of FIGS. 1 and 2, a cable 11 housed in a sheath 11 ′ and controlled by a pull tab 12 makes it possible to pivot the lever 4 against the action of its spring 6. In the variant of FIGS. 3 and 4, the lever 4 is made of mild steel and is subjected to the action of electromagnets 13 connected to an electrical supply by means of a switch 14. L actuation of the switch 14 produces the attraction of the lever 4 and its pivoting against the action of its spring 6.

Dans la variante des figures 5 et 6, l'axe 5 est parallèle à l'axe du barillet et comporte un bec 15 coopérant avec une encoche 16 ménagée dans une came 17 entraînée par le barillet 1. Pour éliminer l'action de blocage du barillet lors de la rotation dans le sens des aiguilles d'une montre (sur le dessin), le bec 15 comporte un bord arrondi 15'. In the variant of Figures 5 and 6, the axis 5 is parallel to the axis of the barrel and has a spout 15 cooperating with a notch 16 formed in a cam 17 driven by the barrel 1. To eliminate the blocking action of the barrel when rotated clockwise (in the drawing), the spout 15 has a rounded edge 15 '.

Dans la variante des figures 7 à 9, l'axe 5 est à nouveau orthogonal à l'axe de la serrure mais le levier est dans un plan radial au barillet 1. Le barillet 1 comporte une saillie radiale 18 qui vient buter contre le levier 4 et interdit la rotation du barillet. Une traction sur le câble 11 libère le barillet. In the variant of FIGS. 7 to 9, the axis 5 is again orthogonal to the axis of the lock but the lever is in a plane radial to the barrel 1. The barrel 1 has a radial projection 18 which abuts against the lever 4 and prohibits rotation of the barrel. A pull on the cable 11 releases the barrel.

Le cache 19 représenté à la figure 10 comporte les indications de position angulaire du barillet Arrêt (St),
Accessoires (Acc), Marche (M) et Démarreur (D). Le blocage angulaire du barillet 1 par le levier 4 peut être provoqué en position Acc dans laquelle l'alimentation du moteur du véhicule est coupée. The cover 19 shown in FIG. 10 includes the indications of the angular position of the Stop barrel (St),
Accessories (Acc), Step (M) and Starter (D). The angular blocking of the barrel 1 by the lever 4 can be caused in the Acc position in which the supply to the vehicle engine is cut off.
