- La figure 11 est une vue en coupe selon la ligne XI-XI de la figure 10. - Les figures 1 à 3 montrent schématiquement un premier mode de réalisation d'un agencement antivol selon la présente invention. Cet agencement est destiné à être fixé sur la couronne ou jante 1 d'un volant de direction 2 d'un véhicule d'automobile de façon à limiter le mouvement de rotation du volant 2 et empêcher ainsi toute personne mal intentionnée de manoeuvrer celui-ci.- Figure 11 is a sectional view along line XI-XI of Figure 10. - Figures 1 to 3 schematically show a first embodiment of an anti-theft arrangement according to the present invention. This arrangement is intended to be fixed to the crown or rim 1 of a steering wheel 2 of a motor vehicle so as to limit the rotational movement of the steering wheel 2 and thus prevent any malicious person from maneuvering it. .
A cet effet, l'agencement antivol comprend essentiellement deux dispositifs en forme de capot ou coquille rigide métallique 4, 5 qui sont montés pivotants l'un par rapport à l'autre, autour d'un axe 6, de façon à pouvoir coiffer une grande partie du volant 2 en venant en appui sur une portion correspondante de la périphérie externe de la couronne 1 du volant, comme on le voit sur la figure 1. A cette fin, chaque capot 4, 5 est arqué en forme au moins approximativement d'un segment de disque cylindrique creux de forme conjuguée à la périphérie externe de la couronne 1 en présentant une section transversale en forme d'un U. Ainsi chaque capot comprend deux flasques 4a, 4b et 5a et 5b, séparés l'un de l'autre d'une distance permettant l'introduction entre ceux-ci de la couronne 1 du volant et raccordés l'un à l'autre par une paroi de fond arquée 4c ou 5c. C'est par la face interne de cette paroi 4c et 5c que les dispositifs en forme de capot ou de coquille viennent en appui contre la couronne 1.
Grâce à leur montage pivotant autour de l'axe 6, les deux capots 4 et 5 peuvent être rapprochés l'un de l'autre pour coiffer et enserrer la périphérie externe de la couronne ou éloignés l'un de l'autre pour pouvoir retirer l'agencement antivol du volant de direction 2. En donnant par exemple au capot 5 une hauteur plus faible qu'au capot 4, le capot 5 peut s'engager dans le capot 4 et rendre ainsi au dispositif antivol un encombrement relativement faible dans sa position de rangement représenté sur la figure 3.To this end, the anti-theft arrangement essentially comprises two devices in the form of a hood or rigid metal shell 4, 5 which are pivotally mounted relative to each other, about an axis 6, so as to be able to cover a large part of the flywheel 2 coming to bear on a corresponding portion of the external periphery of the crown 1 of the flywheel, as can be seen in FIG. 1. To this end, each cover 4, 5 is arched in shape at least approximately d a segment of hollow cylindrical disc of shape conjugated to the external periphery of the crown 1 by presenting a cross-section in the shape of a U. Thus each cover comprises two flanges 4a, 4b and 5a and 5b, separated one of the 'Another of a distance allowing the introduction between them of the crown 1 of the steering wheel and connected to each other by an arcuate bottom wall 4c or 5c. It is by the internal face of this wall 4c and 5c that the devices in the form of a cover or shell come to bear against the crown 1. Thanks to their pivoting mounting around the axis 6, the two covers 4 and 5 can be brought together to cover and enclose the outer periphery of the crown or spaced from each other to be able to remove the anti-theft arrangement of the steering wheel 2. By giving, for example, the cover 5 a lower height than the cover 4, the cover 5 can engage in the cover 4 and thus make the anti-theft device a relatively small size in its storage position shown in Figure 3.
L'agencement antivol 3 comprend des moyens permettant de verrouiller ou de déverrouiller les deux capots 4, 5 angulairement l'un par rapport à l'autre. Ces moyens comprennent une crémaillère 8 en forme d'un arc de cercle qui est monté sur un dispositif de capot, dans l'exemple représenté sur le dispositif capot 5, de façon à s ' étendre dans le plan de pivotement en direction de l'autre dispositif 4. Ce dernier comporte une serrure 9 à pêne 10 et à clé 11. Le pêne 10 est mobile, de façon rectiligne, entre une position de verrouillage des capots 4 et 5 dans leur position angulaire relative, par engrènement de sa face avant dentée dans la denture de la crémaillère 8, sous l'effet d'un ressort 12 et une position dégagée de la crémaillère. Le mouvement du pêne 10 pour se dégager de la crémaillère se fait à 1 ' encontre du ressort 12.The anti-theft arrangement 3 comprises means making it possible to lock or unlock the two covers 4, 5 angularly with respect to one another. These means comprise a rack 8 in the form of a circular arc which is mounted on a cover device, in the example shown on the cover device 5, so as to extend in the pivoting plane in the direction of the another device 4. The latter comprises a lock 9 with a bolt 10 and a key 11. The bolt 10 is movable, in a rectilinear fashion, between a position for locking the covers 4 and 5 in their relative angular position, by meshing its front face toothed in the teeth of the rack 8, under the effect of a spring 12 and a disengaged position of the rack. The movement of the bolt 10 to disengage from the rack is done against the spring 12.
Pour actionner le pêne, la serrure 9 comporte un barillet 13 susceptible d'être entraîné en rotation par la clé 11 et comportant à son extrémité interne un embout excentré 14 qui s'engage dans un évidemment 15 du pêne 10. Ainsi, la rotation du barillet 13 sous l'effet de la clé 11 provoque le déplacement rectiligne du pêne 10, perpendiculairement à l'axe du barillet.To actuate the bolt, the lock 9 comprises a barrel 13 capable of being driven in rotation by the key 11 and comprising at its internal end an eccentric tip 14 which engages in a recess 15 of the bolt 10. Thus, the rotation of the barrel 13 under the effect of the key 11 causes the rectilinear displacement of the bolt 10, perpendicular to the axis of the barrel.
Comme on le voit sur les figures, le dispositif de verrouillage formé par la crémaillère 8 et la serrure 9 est disposé, de préférence, à une certaine distance de l'axe de pivotement 6 mais pourrait être aussi prévu au
niveau de cet axe, comme on le verra plus loin lors de la description d'autres modes de réalisation de l'invention. Il est encore à noter que chaque dispositif de capot 4, 5 pourrait être pourvu d'une partie en saillie 16 formant également poignée permettant le maniement de l'agencement et configuré pour empêcher la rotation du volant 2 lorsque l'agencement est fixé sur celui-ci, conformément à la figure 1.As can be seen in the figures, the locking device formed by the rack 8 and the lock 9 is preferably arranged at a certain distance from the pivot axis 6 but could also be provided in the level of this axis, as will be seen later when describing other embodiments of the invention. It should also be noted that each cover device 4, 5 could be provided with a projecting part 16 also forming a handle allowing the handling of the arrangement and configured to prevent the rotation of the steering wheel 2 when the arrangement is fixed to that -ci, according to figure 1.
Concernant la crémaillère 8, elle a un profil en forme de dents de scie qui permettent un rapprochement des deux dispositifs, mais empêchent un mouvement en arrière sans retrait du pêne par la clé.Regarding the rack 8, it has a profile in the shape of a sawtooth which allows a bringing together of the two devices, but prevents a backward movement without withdrawal of the bolt by the key.
On décrira ci -après d'autres modes de réalisation du dispositif antivol selon l'invention, les éléments identiques ou similaires étant désignés par les mêmes références sur les figures 1 à 3.Other embodiments of the anti-theft device according to the invention will be described below, the identical or similar elements being designated by the same references in FIGS. 1 to 3.
La figure 4 montre un mode de réalisation de l'invention qui n'utilise qu'un seul capot indiqué par 4 et monté pivotant sur l'extrémité d'une tige creuse rigide métallique 17 dont l'autre extrémité est adaptée pour recevoir la serrure 9 dont le barillet est axialement prolongé par une tige 18 portant à son extrémité l'embout 14 d'entraînement du pêne 10. Celui- ci est donc deplaçable perpendiculairement à l'axe de la tige tubulaire 17 en pouvant faire saillie radialement hors du tube à travers une fenêtre 20 pratiquée dans ce tube.Figure 4 shows an embodiment of the invention which uses only one cover indicated by 4 and mounted pivotally on the end of a rigid metal hollow rod 17 whose other end is adapted to receive the lock 9, the barrel of which is axially extended by a rod 18 carrying at its end the end piece 14 for driving the bolt 10. The latter is therefore displaceable perpendicular to the axis of the tubular rod 17, being able to project radially out of the tube through a window 20 made in this tube.
Sur le tube 17 est emmanché un fourreau 21, de façon axialement coulissante qui porte sur sa surface inférieure la crémaillère 8 qui s'étend axialement. Le fourreau 21 porte sur sa surface extérieure un crochet de blocage 22 qui est susceptible de venir en prise sous un rayon 23 du volant de direction 2, par rotation du fourreau 21 autour de la tige tubulaire 17. Dans cette position de verrouillage dans laquelle le capot 14 vient en prise autour de la couronne 1 du volant 2 et le crochet 20 vient en prise sous le rayon 23 du volant, ce
qui entraîne la fixation de l'agencement antivol sur le volet 2, le pêne 10 engrène la denture de la crémaillère 8 en faisant saillie à travers la fenêtre 20 découpée dans la tige 17. La mise en place pour le verrouillage du crochet 22 se fait par un déplacement complexe du fourreau 21 sur la tige 17 combinant un déplacement axial et un déplacement rotatif. Pour permettre ce mouvement, la tige 17 porte sur sa face extérieure un téton 25 qui s'engage dans une rainure appropriée pratiquée dans la face interne du fourreau. Dans une première version de réalisation, la rainure comporte une portion axiale 26 qui s'étend à partir de l'extrémité interne du fourreau jusqu'à un endroit prédéterminé en fonction de l'effet de verrouillage à obtenir, et est angulairement décalée selon un angle prédéterminé de la crémaillère 22 et une rainure annulaire 27 dans laquelle débouche la rainure axiale 26.On the tube 17 is fitted a sheath 21, axially sliding which carries on its lower surface the rack 8 which extends axially. The sleeve 21 carries on its outer surface a locking hook 22 which is capable of engaging under a radius 23 of the steering wheel 2, by rotation of the sleeve 21 around the tubular rod 17. In this locking position in which the hood 14 engages around the crown 1 of the steering wheel 2 and the hook 20 engages under the radius 23 of the steering wheel, this which leads to the fixing of the anti-theft arrangement on the flap 2, the bolt 10 meshes with the teeth of the rack 8 by projecting through the window 20 cut in the rod 17. The positioning for locking the hook 22 is done by a complex displacement of the sheath 21 on the rod 17 combining an axial displacement and a rotary displacement. To allow this movement, the rod 17 carries on its outer face a stud 25 which engages in a suitable groove made in the internal face of the sheath. In a first embodiment, the groove has an axial portion 26 which extends from the internal end of the sleeve to a predetermined location depending on the locking effect to be obtained, and is angularly offset according to a predetermined angle of the rack 22 and an annular groove 27 into which the axial groove 26 opens.
Lors de la fixation de l'agencement antivol sur le volant 2, on engage tout d'abord le capot 4 sur la couronne 1 du volant 2, avec le crochet 22 écarté du rayon 23. Dans cette position angulaire du fourreau 21 par rapport à la tige 17, le téton 25 est engagé dans la rainure axiale 26. Puis on déplace le fourreau sur cette tige axialement jusqu'à ce que le téton 25 parvienne dans la rainure annulaire 27. Ensuite, on fait tourner le fourreau jusqu'à ce que le pêne 10 se trouve en face de la crémaillère 22. Pendant ce mouvement, le pêne est retiré dans la tige et est retenu dans cette position par la clé 10. Puis on permet au pêne de s'engager dans cette crémaillère sous l'effet du ressort 12 par rotation appropriée de la clé.When fixing the anti-theft arrangement on the steering wheel 2, the cover 4 is first of all engaged on the crown 1 of the steering wheel 2, with the hook 22 spaced from the radius 23. In this angular position of the sheath 21 relative to the rod 17, the stud 25 is engaged in the axial groove 26. Then the sheath is moved on this rod axially until the stud 25 reaches the annular groove 27. Then, the sheath is rotated until that the bolt 10 is located opposite the rack 22. During this movement, the bolt is withdrawn in the rod and is retained in this position by the key 10. Then the bolt is allowed to engage in this rack under the effect of spring 12 by appropriate rotation of the key.
Dans une autre version de réalisation, la combinaison de la rainure axiale 26 et de la rainure annulaire 27 peut être remplacée par une rainure hélicoïdale 28 à l'intérieur du fourreau. Le verrouillage se fait donc par un mouvement forcé par le
guidage du téton dans la rainure 28, simultanément axial et rotatif.In another embodiment, the combination of the axial groove 26 and the annular groove 27 can be replaced by a helical groove 28 inside the sheath. Locking is therefore done by a forced movement by the guiding the stud in the groove 28, simultaneously axial and rotary.
La figure 5 montre un mode de réalisation de l'agencement antivol selon l'invention, qui est similaire à l'agencement représenté sur les figures 1 à 3. Ce mode de réalisation se distingue du dernier par le fait que du capot 5 seulement la bande de base 5c destinée à venir en contact avec la face périphérique extérieure de la couronne 1 est conservée et que les flasques supérieure et inférieure sont remplacées par deux éléments 29, 30 en forme d'un U disposés respectivement à l'extrémité de la bande de base 5c et sensiblement à l'endroit où le capot 5 commençait à venir en prise autour de la couronne. L'élément en U extérieur 29 est monté pivotant en 31 sur la bande 5c et celle-ci comporte une articulation 32 juste derrière l'élément en U 30. Concernant l'autre capot portant la référence 4 comme sur la figure 1, il est réduit à la portion 4c qui vient en appui contre la couronne 1. Cette partie de bande 4c est reliée par une articulation 35 à la partie de l'agencement qui comporte la crémaillère 8, la serrure 9 et l'axe d'articulation 6. Pour que les forces de verrouillage soient maximales, la crémaillère 7 est disposée le plus près possible de la couronne, ce qui permet aussi de configurer la partie entre la serrure et l'axe de pivotement 6 en poignée, en créant ainsi des conditions de maniement très ergonométriques . Les articulations 30, 31 et 35 permettent d'obtenir un encombrement minimal à l'état de rangement, la partie 5c et les éléments en U pouvant être repliés dans le capot 4.Figure 5 shows an embodiment of the anti-theft arrangement according to the invention, which is similar to the arrangement shown in Figures 1 to 3. This embodiment is distinguished from the latter by the fact that of the cover 5 only the base band 5c intended to come into contact with the outer peripheral face of the crown 1 is preserved and the upper and lower flanges are replaced by two U-shaped elements 29, 30 arranged respectively at the end of the band base 5c and substantially at the point where the cover 5 began to engage around the crown. The external U-shaped element 29 is pivotally mounted at 31 on the strip 5c and the latter has a hinge 32 just behind the U-shaped element 30. With regard to the other cover bearing the reference 4 as in FIG. 1, it is reduced to the portion 4c which comes to bear against the crown 1. This part of the band 4c is connected by a hinge 35 to the part of the arrangement which comprises the rack 8, the lock 9 and the hinge pin 6. In order for the locking forces to be maximum, the rack 7 is arranged as close as possible to the crown, which also makes it possible to configure the part between the lock and the pivot axis 6 as a handle, thereby creating handling conditions. very ergonometric. The joints 30, 31 and 35 make it possible to obtain a minimum space requirement in the storage state, the part 5c and the U-shaped elements being able to be folded in the cover 4.
La figure 5 montre une version de réalisation de la partie d'actionnement de l'agencement antivol dont la particularité réside dans le fait que la crémaillère 8 et la serrure 9 sont disposés près de l'axe de pivotement 6. Pour assurer un bon guidage des deux dispositifs articulés, on prévoit près de la couronne 1
un dispositif de guidage 36 comportant essentiellement une tige 37 solidaire d'un dispositif et adaptée pour s'emmancher dans un élément tubulaire 38 solidaire de l'autre dispositif. Les figures 7 à 9 montrent un mode de réalisation de l'agencement antivol selon l'invention, dans lequel les deux dispositifs de blocage du volant 2, portant les références 40 et 41 sont montés pivotants autour d'un dispositif à axe de pivotement horizontal 42 de façon à venir en prise avec le volant 2 par au-dessus et par en- dessous. A cette fin, le dispositif 40 est réalisé sous forme d'un bras relativement large qui porte à son extrémité libre un disque sensiblement circulaire 43 qui vient lors du blocage du volant en appui sur la partie centrale du volant, tandis que le dispositif inférieur 41 est réalisé sous forme d'un bras pourvu à son extrémité d'une partie en fourche 45 adaptée pour venir en prise autour de la partie de base de forme conique 46 du volant, comme on le voit sur les figures 8 et 9. Le dispositif de blocage supérieur 40 comporte un certain nombre de tenon 47 qui sont disposés de façon à faire saillie vers le bas et à venir en appui latéralement contre les éléments du volant tels que des rayons et la partie centrale, pour assurer un effet de blocage du dispositif 40 sur le volant. Pour permettre l'adaptation de l'agencement selon l'invention à différents types de volants, on peut prévoir sur la partie centrale toute une série de trous 50 de réception des tenons 47 et l'adaptation au volant se fait par insertion des tenons d'immobilisation dans des trous 50 appropriés.FIG. 5 shows an embodiment of the actuating part of the anti-theft arrangement, the particularity of which lies in the fact that the rack 8 and the lock 9 are arranged near the pivot axis 6. To ensure good guidance of the two articulated devices, provision is made near the crown 1 a guide device 36 essentially comprising a rod 37 secured to a device and adapted to be fitted into a tubular element 38 secured to the other device. Figures 7 to 9 show an embodiment of the anti-theft arrangement according to the invention, in which the two steering wheel locking devices 2, bearing the references 40 and 41 are pivotally mounted around a device with a horizontal pivot axis 42 so as to engage with the flywheel 2 from above and from below. To this end, the device 40 is produced in the form of a relatively wide arm which carries at its free end a substantially circular disc 43 which comes when the steering wheel locks in abutment on the central part of the steering wheel, while the lower device 41 is made in the form of an arm provided at its end with a fork portion 45 adapted to engage around the base portion of conical shape 46 of the steering wheel, as seen in Figures 8 and 9. The device upper locking 40 has a number of tenons 47 which are arranged so as to project downwards and to come into abutment laterally against the elements of the steering wheel such as spokes and the central part, to ensure a locking effect of the device 40 on the steering wheel. To allow the adaptation of the arrangement according to the invention to different types of flywheels, there can be provided on the central part a whole series of holes 50 for receiving the lugs 47 and the adaptation to the steering wheel is made by inserting the lugs d immobilization in appropriate holes 50.
L'agencement selon les figures 7 à 9 est équipé d'un dispositif de verrouillage à serrure qui est intégré au dispositif de pivotement 42 des deux dispositifs de blocage 40 et 41. Ce type de dispositif de verrouillage pourrait aussi être monté sur les agencements représentés sur les figures 1 et 5. Comme on le voit sur les figures 7 et 9 , la base du dispositif de
blocage 40 présente la forme d'un étrier 52 entre les branches 53 duquel s'engage la base 54 du dispositif de blocage inférieur 42. Cette base est réalisée sous forme d'un pignon 55 accomplissant la fonction de la crémaillère 8 des autres modes de réalisation. Le pignon 55 et les branches d' étrier 53 sont traversées par un tourillon 56 qui est solidaire en rotation du pignon 55 et rotatif dans les branches 53. Dans une des branches est intégrée la serrure 9 de façon que le pêne 10 soit deplaçable perpendiculairement au pignon 55 entre une position d' engrènement de celui-ci et une position dégagée, comme cela a déjà été expliqué plus haut à l'occasion de la description des autres modes de réalisation. Les figures 10 et 11 montrent encore un autre mode de réalisation de l'agencement antivol selon l'invention. Cet agencement comporte un boîtier 60 dont les parois supérieure et inférieure sont formées par des plaques sensiblement circulaires 61 et 62, de façon à pouvoir être posées sur la partie centrale 63 du volant 2 comme le montre la figure 11. Dans le boîtier 60 est monté rotative autour d'un tourillon 64 une plaque triangulaire isocèle 65 qui s'étend parallèlement aux plaques 61 et 62 et qui portent, articulée à chaque angle, une bielle 66. A l'extrémité libre de chaque bielle est articulée un capuchon de blocage 68 ayant une section transversale en forme d'un C adapté pour s ' engager autour de la couronne 1 du volant de direction 2, comme on le voit sur la figure 11. Celle-ci illustre aussi que, lorsque le boîtier 60 repose sur la partie centrale 63 du volant, les trois capuchons 68 se trouvent dans le même plan que la couronne 1. Comme il ressort de la figure 10, lorsque, à l'état posé sur le volant 63, la rotation de la plaque 65 dans la direction de la flèche FI provoque l'engagement des capuchons 68 sur la couronne 1 à partir de la position dégagée des capuchons montrés en traits interrompus.
La partie centrale de la plaque 65 porte une couronne 70 dont la face interne comporte une denture 71 accomplissant la fonction de la crémaillère décrite précédemment. A l'intérieur de cette couronne 70 fait saillie une serrure 9 qui est montée sur la plaque supérieure 61 du boîtier 60 et qui comprend le pêne des autres modes de réalisation dont la face frontale est maintenant conformée pour engrener la denture 71 sous l'effet du ressort 12. Comme auparavant, le déplacement est commandé par une clé 11.The arrangement according to FIGS. 7 to 9 is equipped with a locking locking device which is integrated into the pivoting device 42 of the two locking devices 40 and 41. This type of locking device could also be mounted on the arrangements shown. in Figures 1 and 5. As seen in Figures 7 and 9, the base of the blocking 40 has the form of a stirrup 52 between the branches 53 from which engages the base 54 of the lower blocking device 42. This base is produced in the form of a pinion 55 fulfilling the function of the rack 8 of the other modes of production. The pinion 55 and the stirrup branches 53 are crossed by a pin 56 which is integral in rotation with the pinion 55 and rotatable in the branches 53. In one of the branches is integrated the lock 9 so that the bolt 10 is displaceable perpendicular to the pinion 55 between a position of engagement thereof and a disengaged position, as has already been explained above when describing the other embodiments. Figures 10 and 11 show yet another embodiment of the anti-theft arrangement according to the invention. This arrangement comprises a housing 60, the upper and lower walls of which are formed by substantially circular plates 61 and 62, so that they can be placed on the central part 63 of the steering wheel 2 as shown in FIG. 11. In the housing 60 is mounted rotatable around a journal 64 an isosceles triangular plate 65 which extends parallel to the plates 61 and 62 and which carry, articulated at each angle, a connecting rod 66. At the free end of each connecting rod is articulated a locking cap 68 having a cross section in the shape of a C adapted to engage around the crown 1 of the steering wheel 2, as can be seen in FIG. 11. This also illustrates that, when the housing 60 rests on the part central 63 of the steering wheel, the three caps 68 are in the same plane as the crown 1. As can be seen in FIG. 10, when, in the state placed on the steering wheel 63, the rotation of the plate 65 in the direction of the arrow he FI causes the engagement of the caps 68 on the crown 1 from the disengaged position of the caps shown in broken lines. The central part of the plate 65 carries a crown 70 whose internal face has a toothing 71 fulfilling the function of the rack described above. Inside this crown 70 projects a lock 9 which is mounted on the upper plate 61 of the housing 60 and which comprises the bolt of the other embodiments whose front face is now shaped to mesh the teeth 71 under the effect of the spring 12. As before, the movement is controlled by a key 11.
La plaque 65 est entraînée en rotation par une poignée 72 montée à l'extrémité d'une tige 73 solidaire de la plaque et faisant saillie de celle-ci. Il est possible de monter la serrure dans cette tige comme dans le cas de la figure 4, le boîtier devant alors comporter la crémaillère sous forme d'un pignon.The plate 65 is rotated by a handle 72 mounted at the end of a rod 73 integral with the plate and projecting from the latter. It is possible to mount the lock in this rod as in the case of Figure 4, the housing then having to include the rack in the form of a pinion.
Concernant le fonctionnement des agencements antivol selon l'invention, il ressort déjà des descriptions des structures qui ont été faites en se référant aux figures. Il suffit donc d'indiquer que, pour la pose des agencements selon les figures 1, 5, 9 et 10 on écarte les deux dispositifs de blocage l'un de l'autre, avec la clé 10 dans la position de retrait du pêne 10 de la crémaillère 8, du pignon 54 ou de la couronne 70. Après la mise en place des capots 4, 5, des éléments en forme de U 28, 29, ou des capuchons 68 sur la couronne 1 du volant 2 ou des dispositifs de blocage 40 et 41 sur et sous le volant 2, on fait tourner la clé dans sa position de verrouillage par le pêne 10 sous l'effet du ressort 12. Etant donné le profil en dents de scie, seulement un retrait du pêne 10 à l'aide de la clé 11 peut permettre le déverrouillage de l'agencement. Concernant le mode de réalisation de la figure 4, la mise en place nécessite la rotation du fourreau 21 d'une position dégagée des rayons du volant dans la position représentée dans laquelle le crochet vient en prise sous un des rayons .
Regarding the operation of the anti-theft arrangements according to the invention, it already emerges from the descriptions of the structures which have been made with reference to the figures. It suffices therefore to indicate that, for the fitting of the arrangements according to FIGS. 1, 5, 9 and 10, the two locking devices are moved apart from one another, with the key 10 in the position of withdrawal of the bolt 10 of the rack 8, of the pinion 54 or of the crown 70. After the installation of the covers 4, 5, of the U-shaped elements 28, 29, or of the caps 68 on the crown 1 of the flywheel 2 or of the blocking 40 and 41 on and under the steering wheel 2, the key is rotated in its locking position by the bolt 10 under the effect of the spring 12. Given the sawtooth profile, only one withdrawal of the bolt 10 to the using the key 11 can allow the arrangement to be unlocked. Regarding the embodiment of Figure 4, the establishment requires rotation of the sleeve 21 from a position disengaged from the spokes of the steering wheel in the position shown in which the hook engages under one of the spokes.
