Description

Dispositif de verrouillage d'une serrure dans un boîtier.Device for locking a lock in a housing.

L'invention concerne un dispositif de verrouillage d'une ser-.The invention relates to a locking device for a service.

rure dans un boîtier, du type comprenant une barrette de verrouillage logée dans un évidement du stator de la serrure, ladite barrette comprenant une saillie traversant un trou dudit boîtier, le rotor de la serrure comprenant un évidement radial qui, dans une position angulaire du rotor différente de la position de verrouillage, est en regard d'un talon de la barrette opposée à ladite saillie.groove in a housing, of the type comprising a locking bar housed in a recess of the stator of the lock, said bar comprising a projection passing through a hole in said housing, the rotor of the lock comprising a radial recess which, in an angular position of the rotor different from the locking position, is opposite a heel of the bar opposite to said projection.

Ce dispositif de verrouillage connu, qui est par exemple utilisé pour le montage d'un antivol de direction d'un véhicule automobile dans un logement de la colonne de direction, permet un montage et un démontage de la serrure lorsque le rotor est dans la position angulaire indiquée précédemment, c'est-à-dire qu'il a été amené à cette position angulaire au moyen de la clé codée convenable, par exemple la position "garage". This known locking device, which is for example used for mounting a steering lock for a motor vehicle in a housing of the steering column, allows mounting and dismounting of the lock when the rotor is in the position angular indicated previously, that is to say that it was brought to this angular position by means of the suitable coded key, for example the position "garage".

Le verrou doit être complété par une vis traversant le boîtier et fixée dans le corps afin d'éviter un démontage accidentel lorsque le rotor passe par la position angulaire précitée et que la barrette peut s'effacer par gravité. En outre, dans le cas d'un véhicule automobile, la barrette est une source de bruit du fait des vibrations qu'elle reçoit lorsque le véhicule roule.The lock must be completed by a screw passing through the housing and fixed in the body in order to avoid accidental disassembly when the rotor passes through the aforementioned angular position and the bar can disappear by gravity. In addition, in the case of a motor vehicle, the bar is a source of noise due to the vibrations it receives when the vehicle is moving.

La présente invention vise à supprimer ces inconvénients des dispositifs de verrouillage connus
A cet effet, le dispositif selon ltinvention est caractérisé par le fait que ladite barrette est basculante et rappelée en position de verrouillage par un ressort et un ressortlame cambré est ancré dans le stator de serrure en formant l'axe de basculement de la barrette et son extrémité libre coopère avec ladite barrette en position de verrouillage de la serrure dans le boîtier.
The present invention aims to eliminate these drawbacks of known locking devices
To this end, the device according to the invention is characterized in that the said bar is tiltable and returned to the locked position by a spring and a cambered leaf spring is anchored in the lock stator by forming the axis of tilting of the bar and its free end cooperates with said bar in the locking position of the lock in the housing.

Le ressort de rappel interdit tout démontage accidentel par effacement de la barrette, tandis que le ressort-lame évite les oscillations de cette-barette et le bruit résultant. En outre, le montage automatique de la serrure dans le boîtier est possible, ce qui était pratiquement impossible auparavant.The return spring prevents any accidental disassembly by erasing the bar, while the leaf spring prevents the oscillations of this bar and the resulting noise. In addition, automatic mounting of the lock in the housing is possible, which was practically impossible before.

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 coupe axiale d'une partie d'une serrure antivol de direction équipée d'un dispositif de verrouillage selon un exemple de réalisation de l'invention, avant montage dans un boîtier; - la figure 2 est une vue en coupe selon la ligne A de la figure 1; - la figure 3 est une vue en coupe longitudinale de la serrure des figures 1 et 2 en cours de montage dans une colonne de direction; - la figure 4 est analogue aux figures 1 et 3, après montage; et - la figure 5 est une vue en coupe selon la ligne B de la figure 4.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 view in axial section of a part of a steering anti-theft lock equipped with a device locking according to an exemplary embodiment of the invention, before mounting in a housing; - Figure 2 is a sectional view along line A of Figure 1; - Figure 3 is a longitudinal sectional view of the lock of Figures 1 and 2 during assembly in a steering column; - Figure 4 is similar to Figures 1 and 3, after assembly; and - Figure 5 is a sectional view along line B of Figure 4.

La serrure comprend un rotor 1 tourillonnant dans un alésage d'un stator 2. Une barrette de verrouillage 3 est logee dans un évidement 4 du stator 2. La barrette 3 comporte à une extrémité une saillie 5 tournée vers l'extérieur et munie d'une face inclinée 6. La barrette 3 comporte en outre, en regard de la saillie 5, un talon 7 tourné vers le rotor 1 et qui, dans une position angulaire du rotor 1 (figures 1 et 3) est en regard d'un évidement radial 8 du rotor 1, cette position angulaire étant différente de la position de verrouillage de la serrure. The lock comprises a rotor 1 swiveling in a bore of a stator 2. A locking bar 3 is housed in a recess 4 of the stator 2. The bar 3 has at one end a projection 5 facing outwards and provided with an inclined face 6. The bar 3 further comprises, opposite the projection 5, a heel 7 turned towards the rotor 1 and which, in an angular position of the rotor 1 (FIGS. 1 and 3) faces a recess radial 8 of rotor 1, this angular position being different from the locking position of the lock.

La barrette 3 est soumise à l'action d'un ressort hélicoïdal de compression 9 en appui sur le fond de l'évidement 4, le ressort 9 tendant à repousser la barrette 3 vers l'extérieur.The bar 3 is subjected to the action of a helical compression spring 9 bearing on the bottom of the recess 4, the spring 9 tending to push the bar 3 outwards.

En outre, un ressort-lame cambré 10 est ancré à une extrémité 11 dans le stator 2 et son extrémité libre 12 coopère avec la barrette 3 au voisinage de la saillie 5. La barrette 3 est donc maintenue par l'action antogoniste du ressort 9 et de la lame 10-pendant le montage de la serrure.In addition, a cambered leaf spring 10 is anchored at one end 11 in the stator 2 and its free end 12 cooperates with the bar 3 in the vicinity of the projection 5. The bar 3 is therefore held by the antogonistic action of the spring 9 and the blade 10-during assembly of the lock.

Pour le montage, la serrure est placée dans la position.angulaire du rotor 1 dans laquelle l'évidement 8 du rotor 1 est en regard du talon 7 de la barrette 3. On fait coulisser la serrure dans un logement de la colonne de direction 13 munie d'une fenêtre 14 (figures 3 et 4), de la gauche vers la droite (sur le dessin).For mounting, the lock is placed in the angular position.of the rotor 1 in which the recess 8 of the rotor 1 is opposite the heel 7 of the bar 3. The lock is made to slide in a housing in the steering column 13 provided with a window 14 (Figures 3 and 4), from left to right (in the drawing).

La coopération du bord incliné 6 de la saillie 5 avec le bord de la colonne 14 fait basculer la barrette 3 dans le sens des aiguilles d'une montre (sur le dessin), autour du point d'ancrage de la lame 10, l'extrémité libre 12 de la lame 10 guittant le contact avec la barrette 3 et le ressort 9 se comprimant (figure 3). Le talon 7 s'enfonce dans l'évidement 8 du rotor 1 et la saillie 5 s'efface complètement à l'intérieur de la colonne 13. A la fin de l'enfoncement de la serrure, la saillie 5 est en regard de la fenêtre 14 et le ressort 9 ramène la barrette 3 vers l'extérieur, la saillie 5 logée dans la fenêtre 14 verrouillant la serrure par rapport à la colonne de direction 13. Ce montage peut se faire facilement, en automatique, par simple translation.The cooperation of the inclined edge 6 of the projection 5 with the edge of the column 14 causes the bar 3 to tilt clockwise (in the drawing), around the blade anchor point 10, the free end 12 of the blade 10 making contact with the bar 3 and the compressing spring 9 (FIG. 3). The heel 7 is inserted into the recess 8 of the rotor 1 and the projection 5 disappears completely inside the column 13. At the end of the pressing of the lock, the projection 5 is opposite the window 14 and the spring 9 brings the bar 3 outwards, the projection 5 housed in the window 14 locking the lock relative to the steering column 13. This assembly can be done easily, automatically, by simple translation.

Quand on fait pivoter le rotor 1 au moyen de sa clé, le talon 7 est en regard d'une portion pleine du rotor 1 (figure 4).When the rotor 1 is pivoted by means of its key, the heel 7 is opposite a solid portion of the rotor 1 (FIG. 4).

L'action antagoniste du ressort 9 et de la lame 10 empêche la barrette 3 de vibrer. The antagonistic action of the spring 9 and of the blade 10 prevents the bar 3 from vibrating.

Le démontage se fait, comme à l'accoutumée, en ramenant le rotor 1 à sa position angulaire des figures 1 et 3 et en enfonçant la saillie 5 au moyen d'un outil adéquat. Disassembly is carried out, as usual, by bringing the rotor 1 back to its angular position in FIGS. 1 and 3 and by driving in the projection 5 by means of a suitable tool.
