Abstract

The clutch bolt comprises a stator, an intermediate socket and a rotor (12) which rotates a lock control lever. The rotor carries parts for locking it relative to the socket and de-clutching parts which, through rotation of the socket with the aid of a key, rotate the rotor and de-clutch the coupling of the rotor and the control lever. The rotor comprises two independent parts (12a,12b) which are coupled to rotate. The rear part carries the locking parts (112,116) whereas the front part carries the de-clutching and coupling parts (87). The rear part of the rotor has an annular groove (134) which allows radially outwards separation of the branches of a pin which engages in the stator rear end.

Description

L'invention concerne un verrou à débrayage axial perfectionné pour un mécanisme de serrure de véhicule automobile.The invention relates to an axial release lock improved for a vehicle lock mechanism automobile.

L'invention concerne plus particulièrement un verrou débrayable, notamment pour un mécanisme de serrure de véhicule automobile, du type dans lequel le verrou comporte un stator fixe, une douille intermédiaire tubulaire qui est montée à rotation autour de son axe dans le stator et qui est fixe axialement par rapport au stator, un rotor qui est monté à rotation dans la douille, qui est fixe axialement dans la douille, et qui est susceptible d'entraíner en rotation un levier de commande de la serrure, et du type dans lequel le rotor porte des moyens de verrouillage du rotor par rapport à la douille, et des moyens de débrayage qui, sous l'effet d'une rotation de la douille par rapport au stator consécutive à l'entraínement en rotation du rotor à l'aide d'une clé non conforme, débraye l'accouplement du rotor avec le levier de commande.The invention relates more particularly to a lock disengageable, especially for a lock mechanism motor vehicle, of the type in which the lock comprises a fixed stator, a tubular intermediate sleeve which is rotatably mounted about its axis in the stator and which is axially fixed relative to the stator, a rotor which is mounted at rotation in the socket, which is fixed axially in the socket, and which is likely to cause a lever to rotate control of the lock, and of the type in which the rotor carries means for locking the rotor relative to the bush, and declutching means which, under the effect of a rotation of the socket in relation to the stator following the drive in rotation of the rotor using an incorrect key, disengages coupling the rotor with the control lever.

L'adjonction d'un mécanisme de débrayage sur un tel verrou permet d'éviter que celui-ci ne soit "forcé". En effet, si une fausse clé, ou tout autre outil plat de forme adéquate, est introduite dans le rotor, et si on tente alors d'entraíner en rotation le rotor, le mécanisme de débrayage permet au rotor et à la douille intermédiaire de pivoter librement à l'intérieur du stator sans que s'exercent sur les paillettes des efforts trop importants.The addition of a declutching mechanism to such a lock prevents it from being "forced". Indeed, if a false key, or any other flat tool of adequate shape, is introduced into the rotor, and if we then try to drive in rotation of the rotor, the release mechanism allows the rotor and the intermediate sleeve to pivot freely inside the stator without exerting too much effort on the glitter important.

En effet, en présence d'efforts trop importants, les paillettes sont susceptibles d'être détériorées ou d'être escamotées, en force, ce qui permet alors de déverrouiller le verrou sans la clé conforme.Indeed, in the presence of excessive efforts, the glitter is likely to be deteriorated or to be retracted, in force, which then unlocks the lock without the correct key.

Divers mécanismes ont déjà été proposés pour réaliser un tel débrayage. Un exemple d'un tel mécanisme est décrit et représenté dans le document FR-A-2.748.513. Various mechanisms have already been proposed for achieve such a clutch. An example of such a mechanism is described and represented in document FR-A-2,748,513.

Bien entendu, de manière connue, le codage du verrou est assuré par les paillettes qui permettent, par un jeu de combinaisons, d'individualisé le verrou destiné à un véhicule particulier. Ce verrou particulier est destinée à n'être ouvert que par la clé conforme dont le profil est adapté au jeu de paillettes installé dans le rotor. Ainsi, à chaque verrou, et donc à chaque véhicule, il est associé une clé particulière qui doit donc "accompagner" le véhicule au cours de son montage dès que le verrou est installé sur le véhicule.Of course, in known manner, the coding of the lock is ensured by the sequins which allow, by a play combinations, individualized the lock for a particular vehicle. This particular lock is intended to be open only with the compliant key whose profile is suitable for the game of glitter installed in the rotor. So with each lock, and so with each vehicle, there is associated a particular key which must therefore "accompany" the vehicle during its assembly as soon as the lock is installed on the vehicle.

Afin de simplifier la gestion de l'appariement de la clé avec le véhicule, il est donc apparu que cet appariement devait se faire le plus tard possible dans le cours du montage du véhicule. Cependant, le verrou interagissant notamment avec la serrure et divers leviers de commande portés par la portière du véhicule, le montage du verrou ne peut généralement se faire que très tard dans le cours du montage du véhicule. Cela est d'autant plus vrai dans le cas des verrous de type débrayable qui comportent de nombreuses pièces interposées entre le rotor du verrou et levier de commande de la serrure.In order to simplify the management of key pairing with the vehicle, it therefore appeared that this pairing should be done as late as possible during the assembly of the vehicle. However, the lock interacting in particular with the lock and various control levers carried by the door of the vehicle, mounting the lock cannot generally be do this very late in the vehicle assembly process. That is all the more true in the case of type locks disengageable with many interposed parts between the lock rotor and the lock control lever.

L'invention a donc pour but, dans le cadre d'un verrou débrayable, de proposer un verrou qui comporte des moyens pour pouvoir apparier le plus tard possible la clé et le véhicule.The object of the invention is therefore, in the context of a lock disengageable, to propose a lock which includes means to be able to pair the key and the vehicle as late as possible.

Dans ce but, l'invention propose un verrou débrayable, notamment pour un mécanisme de serrure de véhicule automobile, du type dans lequel le verrou comporte un stator fixe, une douille intermédiaire tubulaire qui est montée à rotation autour de son axe dans le stator et qui est fixe axialement par rapport au stator, un rotor qui est monté à rotation dans la douille, qui est fixe axialement dans la douille, et qui est susceptible d'entraíner en rotation un levier de commande de la serrure, et du type dans lequel le rotor porte des moyens de verrouillage du rotor par rapport à la douille, et des moyens de débrayage qui, sous l'effet d'une rotation de la douille par rapport au stator consécutive à l'entraínement en rotation du rotor à l'aide d'une clé non conforme, débraye l'accouplement du rotor avec le levier de commande, caractérisé en ce que le rotor comporte deux parties indépendantes qui sont accouplées en rotation et parmi lesquelles une partie arrière porte les moyens de verrouillage tandis qu'une partie avant porte les moyens de débrayage et d'accouplement avec le levier de commande, de telle sorte que le verrou est susceptible d'être monté sur le véhicule en étant entièrement assemblé à l'exception de la partie arrière du rotor qui porte les moyens de verrouillage, et en ce que la partie arrière du rotor qui porte les moyens de verrouillage est susceptible d'être assemblée ultérieurement en étant engagée axialement d'arrière en avant dans la douille du verrou précédemment monté sur le véhicule.To this end, the invention proposes a lock disengageable, especially for a lock mechanism motor vehicle, of the type in which the lock comprises a fixed stator, a tubular intermediate sleeve which is rotatably mounted about its axis in the stator and which is axially fixed relative to the stator, a rotor which is mounted at rotation in the socket, which is fixed axially in the socket, and which is likely to cause a lever to rotate control of the lock, and of the type in which the rotor carries means for locking the rotor relative to the bush, and declutching means which, under the effect of a rotation of the socket in relation to the stator following the drive in rotation of the rotor using an incorrect key, disengages coupling the rotor with the control lever, characterized in that the rotor has two parts independent which are coupled in rotation and among which a rear part carries the locking means while a front part carries the declutching means and coupling with the control lever, so that the lock is capable of being mounted on the vehicle while being fully assembled except for the rear part of the rotor which carries the locking means, and in that the part rear of the rotor which carries the locking means is likely to be assembled later by being engaged axially from back to front in the latch socket previously mounted on the vehicle.

On a représenté sur la figure 1 un verrou rotatif 10 d'axe longitudinal A1 comportant des moyens de débrayage.FIG. 1 shows a rotary lock 10 with a longitudinal axis A1 comprising declutching means.

Le verrou 10 comporte essentiellement un rotor 12 qui est monté tournant, autour de l'axe A1, à l'intérieur d'un stator 14, avec interposition entre les deux d'une douille intermédiaire 16.The lock 10 essentially comprises a rotor 12 which is mounted to rotate, around the axis A1, inside a stator 14, with interposition between the two of a socket intermediate 16.

Conformément aux enseignement de l'invention, le rotor 12 est divisée en deux parties indépendantes, arrière 12a et avant 12b qui comportent des moyens d'accouplement en rotation autour de l'axe A1. Lorsque le rotor 12 est entièrement monté dans le verrou 10, les deux parties 12a et 12b sont accouplées de manière à se comporter comme si le rotor 12 était d'une pièce.In accordance with the teaching of the invention, the rotor 12 is divided into two independent parts, rear 12a and before 12b which include coupling means in rotation around the axis A1. When the rotor 12 is fully mounted in latch 10, the two parts 12a and 12b are coupled so as to behave as if the rotor 12 was one piece.

Le rotor 12 est destiné à être entraíné en rotation à l'aide d'une clé (non représentée) introduite axialement d'arrière en avant à l'intérieur de la partie arrière 12a du rotor 12 au travers d'une entrée de clé 18 agencée dans une face transversale arrière 20 de la partie arrière 12a, laquelle face 20 est destinée par exemple à affleurer à l'extérieur d'un panneau de carrosserie (non représenté) du véhicule.The rotor 12 is intended to be rotated at using a key (not shown) inserted axially from back to front inside the rear part 12a of the rotor 12 through a key entry 18 arranged in one face rear transverse 20 of the rear part 12a, which face 20 is intended for example to be flush with the outside of a vehicle body panel (not shown).

L'extrémité axiale avant 22 de la partie avant 12b du rotor 12 est destinée à entraíner en rotation un levier de commande 24 d'un mécanisme de serrure (non représenté) pour autoriser la condamnation et la décondamnation d'un ouvrant du véhicule.The front axial end 22 of the front part 12b of the rotor 12 is intended to rotate a lever control 24 of a lock mechanism (not shown) to authorize the conviction and unlocking of a opening the vehicle.

Le rotor 12 est susceptible d'entraíner en rotation le levier de commande 24, uniquement en présence d'une clé conforme, par l'intermédiaire d'un entraíneur 26 qui est mobile axialement dans le verrou 10, sous l'action d'un indexeur 28, entre une position embrayée dans laquelle il lie en rotation le rotor 12 et le levier de commande 24, et une position débrayée dans laquelle le rotor 12 n'est plus susceptible d'entraíner le levier 24 en rotation et dans laquelle l'entraíneur 26 assure le blocage en rotation du levier 24 par rapport au stator 14 du verrou 10.The rotor 12 is capable of rotating the control lever 24, only in the presence of a key compliant, via a coach 26 which is movable axially in the latch 10, under the action of an indexer 28, between a engaged position in which it rotates the rotor 12 and the control lever 24, and a disengaged position in which the rotor 12 is no longer likely to cause the lever 24 in rotation and in which the coach 26 ensures the rotation lock of the lever 24 relative to the stator 14 of the lock 10.

Le rotor 12, le stator 14 et la douille intermédiaire 16 sont immobiles en translation selon l'axe A1 l'un par rapport à l'autre et un ressort hélicoïdal de compression 30 est interposé entre le rotor 12 et l'entraíneur 26 pour solliciter ce dernier axialement vers l'avant vers sa position embrayée.The rotor 12, the stator 14 and the intermediate sleeve 16 are stationary in translation along the axis A1, one with respect to the other and a helical compression spring 30 is interposed between the rotor 12 and the driver 26 to urge the latter axially forward towards its engaged position.

Comme on peut le voir sur les figures 1 et 2, le stator 14 est de forme générale tubulaire cylindrique et il comporte des moyens non représentés qui permettent le montage et la fixation du verrou 10 sur le véhicule.As can be seen in Figures 1 and 2, the stator 14 is of generally cylindrical tubular shape and it comprises means not shown which allow mounting and fixing the lock 10 on the vehicle.

De manière connue, la partie arrière 12a du rotor 12 est destiné à recevoir des paillettes 32 agencées dans des plans transversaux qui se succèdent à intervalles réguliers selon la direction de l'axe A1 du verrou 10 et qui sont reçues dans des logements correspondants 34 du rotor 12 qui débouchent sur un tronçon avant 86. Selon l'invention, la partie arrière 12a du rotor 12, qui porte les paillettes 32, forme la partie codante de rotor du verrou, c'est-à-dire celle qui permet d'identifier une clé conforme.In known manner, the rear part 12a of the rotor 12 is intended to receive glitter 32 arranged in successive transverse planes at regular intervals in the direction of the axis A1 of the latch 10 and which are received in corresponding housings 34 of the rotor 12 which lead to a front section 86. According to the invention, the rear part 12a of the rotor 12, which carries the flakes 32, forms the rotor coding part of the bolt, i.e. the part which identifies a compliant key.

Les paillettes 32 sont en effet mobiles radialement dans le rotor 12 et elles sont sollicitées élastiquement vers une position saillante dans laquelle elles dépassent partiellement à l'extérieur des logements 34 du rotor 12.The flakes 32 are indeed radially movable in the rotor 12 and they are elastically biased towards a protruding position in which they protrude partially outside the housings 34 of the rotor 12.

Au contraire, lorsqu'une clé conforme est introduite à l'intérieur du rotor 12, les paillettes 32 sont entièrement escamotées radialement vers l'intérieur dans la partie arrière 12a du rotor 12.On the contrary, when a conforming key is introduced to inside the rotor 12, the flakes 32 are entirely retracted radially inwards in the rear part 12a of rotor 12.

Ainsi, lorsque la clé conforme est introduite dans le rotor 12, celui-ci peut pivoter librement par rapport à la douille intermédiaire cylindrique 16 et par rapport au stator 14.Thus, when the conforming key is introduced into the rotor 12, it can pivot freely relative to the bush cylindrical intermediate 16 and relative to the stator 14.

Au contraire, si on introduit dans le rotor 12 une clé non conforme, ou tout autre outil, les paillettes 32 ne sont pas entièrement escamotées et sont reçues chacune à l'intérieur d'une fenêtre correspondante 36 agencée dans la douille intermédiaire 16. Ainsi, les paillettes 32 immobilisent en rotation le rotor 12 par rapport à la douille intermédiaire 16 qui, elle, reste libre en rotation par rapport au stator 14.On the contrary, if a key is introduced into the rotor 12 non-compliant, or any other tool, the flakes 32 are not fully retracted and are each received inside a corresponding window 36 arranged in the socket intermediate 16. Thus, the flakes 32 immobilize in rotation of the rotor 12 relative to the intermediate sleeve 16 which remains free to rotate relative to stator 14.

On a représenté de manière plus particulière sur la figure 5 l'indexeur 28.We have represented more particularly on the Figure 5 indexer 28.

L'indexeur comporte notamment un anneau principal 38 et des pattes de guidage 40 qui s'étendent axialement vers l'arrière depuis l'anneau 38 et qui sont destinées à être reçues dans des entailles axiales correspondantes 42 de la douille intermédiaire 16.The indexer notably includes a main ring 38 and guide tabs 40 which extend axially towards the rear from the ring 38 and which are intended to be received in corresponding axial cuts 42 of the sleeve intermediate 16.

Les entailles 42 débouchent axialement vers l'avant dans l'extrémité axiale avant 44 de la douille 16 de sorte que, avec les pattes de guidage 40, elles permettent d'assurer la liaison en rotation permanente de l'indexeur 28 avec la douille intermédiaire 16, tout en laissant subsister la possibilité pour l'indexeur 28 de se déplacer axialement dans le verrou 10.The notches 42 open axially forward in the front axial end 44 of the socket 16 so that, with the guide tabs 40, they ensure the permanent rotation connection of the indexer 28 with the sleeve intermediate 16, while leaving the possibility for the indexer 28 to move axially in the latch 10.

Comme on peut le voir sur la figure 5, les pattes de guidage 40 sont formées en excroissance radialement par rapport à l'anneau 38 de telle sorte que l'anneau 38 puisse être reçu à l'intérieur de l'extrémité axiale avant 44 de la douille 16.As can be seen in Figure 5, the legs of guide 40 are radially protruding by relative to ring 38 so that ring 38 can be received inside the front axial end 44 of the socket 16.

Les pattes de guidage 40 sont au nombre de deux et elles sont diamétralement opposées sur l'anneau 38. Chaque patte 40 comporte également deux ergots 46 qui s'étendent chacun axialement vers l'avant dans le prolongement de la patte 40. Les ergots 46 présentent, en section par un plan tangentiel à l'anneau 38, une forme sensiblement trapézoïdale, symétrique par rapport à la direction axiale, la petite base du trapèze formant un bord avant 48 transversal et la grande base du trapèze formant deux surfaces transversales 50 agencées de part et d'autres des faces longitudinales de la patte de guidage 40 correspondante. L'ergot 46 et la patte 40 correspondante présentent ainsi sensiblement une forme de flèche tournée vers l'avant selon la direction axiale.There are two guide tabs 40 and they are diametrically opposed on the ring 38. Each leg 40 also has two lugs 46 which extend each axially forward in the extension of the tab 40. The lugs 46 have, in section through a plane tangential to the ring 38, a substantially trapezoidal shape, symmetrical about the axial direction, the small base of the trapezoid forming a transverse front edge 48 and the large base trapezoid forming two transverse surfaces 50 arranged on both sides of the longitudinal faces of the tab corresponding guide 40. Lug 46 and lug 40 corresponding thus substantially have a form of arrow facing forward in the axial direction.

Les ergots 46 sont destinés à coopérer avec le stator 14.The pins 46 are intended to cooperate with the stator 14.

A cet effet, et comme on peut le voir plus particulièrement sur la figure 2, le stator 14 comporte, à son extrémité axiale avant 52, un collet radial interne 54 dont la face transversale arrière est étagée de manière à former deux faces annulaires concentriques 58, 60 dont la première, périphérique 58, est agencée axialement en arrière de la seconde, interne 60.To this end, and as can be seen more particularly in Figure 2, the stator 14 has, at its end front axial 52, an internal radial collar 54 whose face rear transverse is stepped so as to form two faces concentric annulars 58, 60 of which the first, peripheral 58, is arranged axially behind the second, internal 60.

Le collet radial 54 est muni d'orifices 62 de forme complémentaire des ergots 46 de l'indexeur 28 si bien que les deux faces 64 qui délimitent angulairement un orifice 62 dans le collet radial 54 forment deux rampes inclinées de telle sorte que le logement 62 soit ouvert vers l'arrière.The radial collar 54 is provided with orifices 62 of shape complementary to the lugs 46 of the indexer 28 so that the two faces 64 which angularly delimit an orifice 62 in the radial collar 54 form two ramps inclined so that that the housing 62 is open towards the rear.

Ainsi, l'indexeur 28 est susceptible d'occuper deux positions axiales dans le stator. Thus, the indexer 28 is likely to occupy two axial positions in the stator.

La première, dite position de repos, correspond à celle dans laquelle les ergots 46 sont en appui axialement vers l'avant dans les orifices correspondants 62 du stator 14.The first, called the rest position, corresponds to that in which the pins 46 are supported axially towards the front in the corresponding holes 62 of the stator 14.

En partant de cette première position, si on provoque le pivotement de l'indexeur 28 autour de son axe A1 dans le stator 14, les ergots 46 sont chassés hors de leur orifice du fait de l'inclinaison des rampes 64 qui délimitent les logements 62, et l'indexeur 28 se retrouve alors en position reculée axialement vers l'arrière dans le stator 14, par exemple en appui par la face avant 48 des ergots 46 contre la face annulaire périphérique 58 du collet radial 54.Starting from this first position, if we provoke the pivoting of the indexer 28 around its axis A1 in the stator 14, the lugs 46 are driven out of their orifice of the made of the inclination of the ramps 64 which delimit the housings 62, and the indexer 28 is then in the retracted position axially backwards in the stator 14, for example in support by the front face 48 of the lugs 46 against the face peripheral annular 58 of the radial collar 54.

Comme on l'a vu plus haut, l'indexeur 28 est lié en rotation au stator intermédiaire 16.As we saw above, the indexer 28 is linked in intermediate stator rotation 16.

De la sorte, si une clé non conforme est introduite dans le rotor 12 et si, à l'aide de celle-ci, on provoque le pivotement du rotor 12 autour de son axe de rotation A1, le rotor 12 entraíne en rotation la douille intermédiaire 16 qui, elle, entraíne l'indexeur 28. L'indexeur 28 est alors déplacé vers l'arrière vers sa position de débrayage par la coopération des ergots 46 avec les rampes inclinées 64 des orifices 62.In this way, if a non-conforming key is introduced in the rotor 12 and if, using this, the pivoting of the rotor 12 around its axis of rotation A1, the rotor 12 rotates the intermediate sleeve 16 which, it drives the indexer 28. The indexer 28 is then moved backward to its declutching position by cooperation lugs 46 with the inclined ramps 64 of the orifices 62.

L'indexeur 28 commande les déplacements en translation de l'entraíneur 26 de manière à faire passer celui-ci d'une position axiale avant embrayée à une position axiale arrière débrayée.The indexer 28 controls the movements in translation of the coach 26 so as to pass it from a forward axial position to an axial position rear disengaged.

L'entraíneur 26, qui est représenté plus particulièrement sur les figures 6 et 7, comporte essentiellement deux tronçons tubulaires coaxiaux successifs, arrière 66 et avant 68, le tronçon arrière 66 étant de plus grand diamètre que le tronçon avant 68.Coach 26, who is shown more particularly in Figures 6 and 7, has essentially two successive coaxial tubular sections, rear 66 and front 68, the rear section 66 being further larger diameter than the front section 68.

Le tronçon arrière 66 comporte, à son extrémité axiale arrière, un collet radial externe 70 dont le diamètre externe est sensiblement égal à celui de l'anneau 38 de l'indexeur 28.The rear section 66 comprises, at its end rear axial, an external radial collar 70 whose diameter external is substantially equal to that of ring 38 of indexer 28.

Le collet radial externe 70 est destiné à coopérer avec les ergots 46 de l'indexeur 28 pour assurer l'accouplement axial de l'indexeur 28 sur l'entraíneur 26.The external radial collar 70 is intended to cooperate with the pins 46 of the indexer 28 to ensure the axial coupling of the indexer 28 on the driver 26.

A cet effet, les ergots 46 comportent chacun, à l'avant, un rebord radial interne 72 de telle sorte que l'ergot 46 présente, en section par un plan radial de l'indexeur 28, une forme de L.To this end, the lugs 46 each have, at the front, an internal radial rim 72 so that the lug 46 has, in section through a radial plane of the indexer 28, a L shape.

L'indexeur 28 est destiné à être monté par engagement, selon la direction transversale, des deux ergots 46 sur le collet radial 70 de l'entraíneur 26, le rebord 72 de chacun des deux ergots 46 étant alors au contact d'une face annulaire avant 74 du collet radial externe 70.The indexer 28 is intended to be mounted by engagement, in the transverse direction, of the two pins 46 on the radial collar 70 of the coach 26, the flange 72 of each of the two pins 46 then being in contact with a face front annular 74 of the external radial collar 70.

L'anneau 38 de l'indexeur 28 est alors en appui axialement vers l'avant entre une face annulaire d'extrémité arrière 76 de l'entraíneur 26 de manière à rendre l'entraíneur 26 et l'indexeur 28 solidaires axialement l'un de l'autre.The ring 38 of the indexer 28 is then in support axially forward between an annular end face rear 76 of the coach 26 so as to make the coach 26 and the indexer 28 axially integral with one another.

Cette liaison permet toutefois à l'entraíneur 26 et à l'indexeur 28 d'être libres en rotation l'un par rapport à l'autre autour de leur axe commun A1.However, this connection allows the coach 26 and the indexer 28 to be free to rotate relative to each other around their common axis A1.

Le tronçon avant 68 de l'entraíneur 26 comporte, sur sa face cylindrique externe, des évidements 77 qui sont destinées à coopérer avec des bras axiaux 78 du levier de commande 24 qui, comme on peut le voir plus particulièrement sur la figure 4, sont formés en relief axialement vers l'arrière depuis une face arrière 82 du levier 24. L'entraíneur 26 et le levier de commande 24 sont destinés à être toujours accouplés en rotation par les évidements 77 et les bras 78, et ce quelle que soit la position axiale de l'entraíneur 26 qui est mobile dans le verrou 10 tandis que le levier 24 est fixe axialement par rapport au stator 14. The front section 68 of the coach 26 comprises, on its outer cylindrical face, recesses 77 which are intended to cooperate with axial arms 78 of the lever command 24 which, as we can see more particularly in Figure 4, are formed in relief axially rearward from a rear face 82 of the lever 24. The coach 26 and the control lever 24 are intended to be always coupled in rotation by the recesses 77 and the arms 78, and what that is the axial position of the coach 26 which is movable in the latch 10 while the lever 24 is axially fixed relative to stator 14.

Le tronçon cylindrique avant 68 de l'entraíneur 26 comporte, à son extrémité axiale avant, un collet radial interne 84.The front cylindrical section 68 of the coach 26 has an internal radial collar at its front axial end 84.

L'entraíneur 26 est destiné à être monté sur la partie avant 12b du rotor 12 qui comporte essentiellement un tronçon arrière 87 qui est prolongé axialement vers l'avant par un tronçon intermédiaire 88 et par un tronçon d'extrémité 90 qui sont de diamètres décroissants.The coach 26 is intended to be mounted on the part front 12b of the rotor 12 which essentially comprises a section rear 87 which is extended axially forwards by a intermediate section 88 and by an end section 90 which are of decreasing diameters.

Le tronçon d'extrémité avant 90 de la partie avant 12b du rotor 12 comporte deux crans d'entraínement 92 qui s'étendent radialement vers l'extérieur, en étant diamétralement opposés l'un par rapport à l'autre, et qui sont destinés à être reçus dans des cavités correspondantes 94 formées dans le collet radial 84 de l'entraíneur 26 lorsque celui-ci est en position embrayée.The front end section 90 of the front part 12b of the rotor 12 comprises two drive notches 92 which extend radially outward, being diametrically opposed to each other, and which are intended to be received in corresponding cavities 94 formed in the radial collar 84 of the coach 26 when it is in the engaged position.

Les cavités 94 de l'entraíneur 26 débouchent radialement vers l'intérieur et axialement vers l'avant et vers l'arrière. Le diamètre de l'ouverture délimitée par le collet radial interne 84 de l'entraíneur 26 est sensiblement équivalent au diamètre externe du tronçon d'extrémité 90 de la partie avant 12b du rotor 12. Par ailleurs, les crans 92 du rotor 12 sont agencés axialement à une distance suffisante de l'extrémité arrière du tronçon d'extrémité 90, délimitée par l'extrémité avant du tronçon intermédiaire 88, pour permettre à l'entraíneur 26 de reculer vers sa position débrayée dans laquelle les crans 92 du rotor 12 sont dégagés des cavités 94 de l'entraíneur 26.The cavities 94 of the coach 26 open radially inward and axially forward and backward. The diameter of the opening delimited by the internal radial collar 84 of the coach 26 is substantially equivalent to the diameter outside of the end section 90 of the front part 12b of the rotor 12. Furthermore, the notches 92 of the rotor 12 are arranged axially at a sufficient distance from the rear end of the end section 90, delimited by the front end of the intermediate section 88, to allow the coach 26 to back to its disengaged position in which the notches 92 of the rotor 12 are released from the cavities 94 of the coach 26.

Le diamètre interne du tronçon tubulaire avant 68 de l'entraíneur 26 est sensiblement égal au diamètre externe du tronçon intermédiaire 88 de la partie avant 12b du rotor 12 de telle sorte que le tronçon intermédiaire 88 puisse être reçu à l'intérieur du tronçon avant 68 de l'entraíneur 26 lorsque celui-ci est en position reculée débrayée. The internal diameter of the front tubular section 68 of the coach 26 is substantially equal to the external diameter of the intermediate section 88 of the front part 12b of the rotor 12 of so that the intermediate section 88 can be received at inside the front section 68 of the coach 26 when the latter is in the retracted position disengaged.

Par ailleurs, le diamètre interne du tronçon tubulaire arrière 66 de l'entraíneur 26 est supérieur à celui du tronçon avant 68 et donc supérieur au diamètre externe du tronçon intermédiaire 88 de la partie avant 12b du rotor 12 de manière à délimiter radialement entre le tronçon intermédiaire 88 et le tronçon arrière 66 de l'entraíneur 26 un espace annulaire dans lequel est logé le ressort de compression 30 qui sollicite l'entraíneur 26 et l'indexeur 28 axialement vers l'avant.In addition, the internal diameter of the tubular section rear 66 of the coach 26 is greater than that of the section before 68 and therefore greater than the external diameter of the section intermediate 88 of the front part 12b of the rotor 12 so to be delimited radially between the intermediate section 88 and the rear section 66 of the coach 26 an annular space in which is housed the compression spring 30 which biases the driver 26 and the indexer 28 axially forward.

Le ressort 30 est en appui axialement vers l'avant contre une face annulaire 96 de l'entraíneur 26 qui est tournée vers l'arrière et qui forme le décrochement entre les tronçons avant 66 et arrière 68 de l'entraíneur 26. Le ressort 30 est par ailleurs en appui axialement vers l'arrière contre une face annulaire transversale 98, tournée vers l'avant, délimitée entre les tronçons arrière 87 et intermédiaire 88 de la partie avant 12b du rotor 12.The spring 30 bears axially forwards against an annular face 96 of the coach 26 which is turned backwards and which forms the step between the sections front 66 and rear 68 of the coach 26. The spring 30 is by elsewhere resting axially rearward against a face transverse annular 98, facing forward, delimited between the rear 87 and intermediate 88 sections of the front part 12b of the rotor 12.

Cette face transversale 98 de la partie avant 12b du rotor 12 est par ailleurs entaillée sur sa périphérie radiale externe de manière à délimiter quatre doigts axiaux 100 qui sont agencés à 90° l'un de l'autre et qui sont destinés à être reçus dans des encoches correspondantes 102 qui sont formées dans une face transversale arrière 104 de l'anneau 38 de l'indexeur 28 lorsque l'indexeur 28 est en position reculée de débrayage.This transverse face 98 of the front part 12b of the rotor 12 is also notched on its radial periphery external so as to delimit four axial fingers 100 which are arranged at 90 ° from each other and which are intended to be received in corresponding notches 102 which are formed in a rear transverse face 104 of the ring 38 of indexer 28 when indexer 28 is in the retracted position clutch release.

Ainsi, lorsque, suite à l'introduction d'une clé non conforme dans le rotor 12, l'indexeur 28 est en position reculée de débrayage, il est immobilisé en rotation par rapport au rotor 12.Thus, when, following the introduction of a non-key compliant in rotor 12, indexer 28 is in position retracted clutch, it is immobilized in rotation relative to to rotor 12.

L'entraíneur 26 comporte par ailleurs des tétons 106 qui s'étendent radialement vers l'extérieur depuis une surface cylindrique externe du tronçon arrière 66 de l'entraíneur 26. Les tétons 106 sont destinés à être reçus, lorsque l'entraíneur 26 est en position reculée débrayée, à l'intérieur d'un logement correspondant 108 formé dans la face transversale avant 110 du collet radial 54 du stator 14.The trainer 26 also includes nipples 106 which extend radially outward from a surface external cylindrical of the rear section 66 of the coach 26. The nipples 106 are intended to be received, when the coach 26 is in the disengaged retracted position, inside a housing correspondent 108 formed in the front transverse face 110 of the radial collar 54 of the stator 14.

L'entraíneur 26 est alors bloqué en rotation par rapport au stator 14.The coach 26 is then locked in rotation by stator report 14.

Les logements 108 du stator 14 s'étendent angulairement selon un arc supérieur à l'arc angulaire correspondant à la dimension transversale des tétons 106. En effet, cela est rendu nécessaire du fait que, lorsque l'entraíneur 26 est reculé vers sa position débrayée par l'indexeur 28, il continue à être entraíné en rotation par le rotor 12, tant qu'il n'a pas atteint sa position débrayée. Ainsi, l'entraíneur 26 est animé d'un mouvement sensiblement hélicoïdal.The housings 108 of the stator 14 extend angularly according to an arc greater than the angular arc corresponding to the transverse dimension of the nipples 106. Indeed, this is made necessary by the fact that when the coach 26 is moved back towards its position disengaged by the indexer 28, it continues to be rotated by the rotor 12, as long as it has not reached its disengaged position. Thus, the coach 26 is animated by a substantially helical movement.

En prévoyant des logements 108 de grande dimension, on évite ainsi que les tétons 106 ne butent contre la face avant 110 du collet radial 64, empêchant ainsi le débrayage du verrou 10.By providing housing 108 large dimension, this prevents the nipples 106 from abutting against the front face 110 of the radial collar 64, thus preventing the disengaging the lock 10.

On veillera toutefois à ne pas choisir des logements 108 de trop grande taille pour limiter tout de même le plus possible les débattements possibles du levier 24 lorsque l'entraíneur 26 est en position débrayée.However, care should be taken not to choose accommodation 108 too large to limit the most possible the possible deflections of lever 24 when the coach 26 is in the disengaged position.

Le fonctionnement du dispositif de débrayage du verrou 10 va maintenant être décrit tout particulièrement en considérant les représentations schématiques en perspective des figures 8 et 9 qui illustrent le positionnement relatif des éléments formant le verrou, respectivement en position embrayée et en position débrayée.The operation of the clutch release device lock 10 will now be described in particular in considering the schematic representations in perspective Figures 8 and 9 which illustrate the relative positioning of the elements forming the lock, respectively in position engaged and in the disengaged position.

Sur la figure 8, on a représenté le verrou 10 lorsque l'indexeur 28 et l'entraíneur 26 sont en position avancée embrayée de manière à permettre, à l'aide d'une clé conforme, de commander la rotation du levier 24. In Figure 8, there is shown the latch 10 when the indexer 28 and the coach 26 are in the advanced position clutched so as to allow, using a conforming key, to control the rotation of the lever 24.

En effet, les ergots 46 de l'indexeur 28 sont alors reçus au fond des orifices 62 du stator 14 de sorte que le ressort 30 sollicite l'ensemble de l'indexeur 28 et de l'entraíneur 26 vers l'avant. Dans le cas de l'utilisation d'une clé conforme, les paillettes 32 sont escamotées à l'intérieur du rotor 12 et la douille intermédiaire 16 est libre en rotation par rapport au rotor 12 et elle est immobilisée par rapport au stator 14 du fait de l'engagement des ergots 46 dans les logements 62. L'entraíneur 26 est en position avancée d'embrayage si bien que, en plus d'être solidaire en rotation du levier 24 par les cannelures complémentaires 77, 78, il est également accouplé en rotation avec le rotor 12 du fait de l'engagement des crans 92 du rotor 12 dans les cavités 94 correspondantes de l'entraíneur 26.Indeed, the lugs 46 of the indexer 28 are then received at the bottom of the orifices 62 of the stator 14 so that the spring 30 stresses all of indexer 28 and the coach 26 forwards. In the case of the use of a compliant key, the flakes 32 are retracted inside the rotor 12 and the intermediate sleeve 16 is free to rotate by relative to rotor 12 and it is immobilized relative to the stator 14 due to the engagement of the lugs 46 in the housings 62. The coach 26 is in the advanced clutch position if although, in addition to being integral in rotation with the lever 24 by the complementary grooves 77, 78, it is also coupled in rotation with the rotor 12 due to the engagement notches 92 of the rotor 12 in the corresponding cavities 94 of the coach 26.

Ainsi, le rotor 12 est à même d'entraíner en rotation le levier 24 pour commander la condamnation ou la décondamnation du mécanisme de serrure.Thus, the rotor 12 is able to drive in rotation lever 24 for controlling the locking or the unlocking of the lock mechanism.

Si, au contraire, une fausse clé est introduite dans le rotor 12, les paillettes 32 maintiennent alors la douille intermédiaire 16 solidaire en rotation du rotor 12 de sorte qu'une tentative de rotation du rotor 12 provoque une rotation relative de la douille 16 par rapport au stator 14, rotation permise par le fait que l'indexeur 28 recule vers sa position de débrayage par la coopération des ergots 46 avec les rampes 64 délimitant les orifices 62 du stator 14.If, on the contrary, a false key is introduced into the rotor 12, the flakes 32 then hold the sleeve intermediate 16 integral in rotation with the rotor 12 so that an attempt to rotate the rotor 12 causes a rotation relative of the socket 16 with respect to the stator 14, rotation allowed by the fact that the indexer 28 moves back to its position of declutching by the cooperation of the lugs 46 with the ramps 64 delimiting the orifices 62 of the stator 14.

L'indexeur 28, en reculant vers sa position de débrayage, entraíne avec lui l'entraíneur 26 en position débrayée ainsi que cela est représenté sur la figure 9.The indexer 28, moving back to its position of declutching, coaches with him 26 in position disengaged as shown in Figure 9.

Dans cette position, les crans 92 du rotor 12 sont dégagés des cavités 94 de l'entraíneur 26 et les tétons 106 de l'entraíneur 26 sont engagés dans les logements 108 du stator 14. L'entraíneur 26 est ainsi immobilisé en rotation et il bloque en rotation le levier 24 grâce aux évidements 77 et aux bras 78 qui restent engagés malgré le déplacement axial relatif de l'entraíneur 26 par rapport au levier 24.In this position, the notches 92 of the rotor 12 are released from the cavities 94 of the coach 26 and the nipples 106 of the coach 26 are engaged in the housings 108 of the stator 14. The coach 26 is thus immobilized in rotation and it blocks in rotation the lever 24 thanks to the recesses 77 and to the arms 78 which remain engaged despite the relative axial displacement of the coach 26 relative to the lever 24.

Par ailleurs, le rotor 12 n'est plus lié en rotation avec l'entraíneur 26 et se retrouve ainsi totalement libre en rotation. Le rotor 12 est ainsi débrayé du reste du mécanisme de la serrure et ne peut plus avoir d'action sur celle-ci.Furthermore, the rotor 12 is no longer linked in rotation with the coach 26 and thus finds itself completely free in rotation. The rotor 12 is thus disengaged from the rest of the mechanism of the lock and can no longer have any action on it.

On a représenté sur la figure 10 une position intermédiaire de l'entraíneur 26 et de l'indexeur 28, entre leurs positions embrayée et débrayée. Cette position est susceptible de survenir après que le verrou a été débrayé et donc l'indexeur 28 et l'entraíneur 26 sont alors initialement en position reculée représentée sur la figure 9.FIG. 10 shows an intermediate position of the coach 26 and of the indexer 28, between their engaged and disengaged positions. This position is likely to occur after the lock has been released and therefore the indexer 28 and the coach 26 are then initially in remote position shown in Figure 9.

En partant de cette position, il est alors possible de faire pivoter le rotor 12 autour de son axe A1, ce qui provoque simultanément le pivotement de l'indexeur 28 par rapport au stator 14. En effet, en présence d'une clé conforme, l'indexeur 28 est entraíné en rotation par le rotor 12 du fait de l'engagement des doigts axiaux 100 du rotor 12 dans les encoches 102 de l'indexeur 28. De plus, si la clé n'est pas conforme, l'indexeur 28 est entraíné simultanément par la douille intermédiaire 16 qui est solidaire du rotor 12 grâce aux paillettes en position saillantes.Starting from this position, it is then possible to rotate the rotor 12 about its axis A1, which causes simultaneously the pivoting of the indexer 28 relative to the stator 14. Indeed, in the presence of a compliant key, the indexer 28 is rotated by the rotor 12 due to the engagement of the axial fingers 100 of the rotor 12 in the notches 102 of the indexer 28. In addition, if the key is not compliant, the indexer 28 is driven simultaneously by the intermediate sleeve 16 which is integral with the rotor 12 thanks to the sequins in projecting position.

Après un certain angle de rotation, les ergots 46 de l'indexeur 28 sont donc susceptibles de se retrouver en regard des orifices correspondants 62 du stator 14. Alors, sous l'action du ressort 30, l'indexeur 28 et l'entraíneur 26 sont déplacés vers l'avant en direction de leur position embrayée.After a certain angle of rotation, the lugs 46 of the indexer 28 are therefore likely to be found opposite corresponding orifices 62 of the stator 14. So, under the action of the spring 30, the indexer 28 and the driver 26 are moved forward toward their engaged position.

Toutefois, il est alors peu probable que les crans 92 du rotor 12 soient en exacte correspondance avec les cavités 94 correspondantes de l'entraíneur 26. De la sorte, le collet radial 84 se retrouve en butée axialement vers l'avant contre une face arrière des crans 92, empêchant ainsi l'entraíneur 26 d'atteindre sa position embrayée. On se retrouve alors dans la configuration qui est représentée sur la figure 10, en position intermédiaire de l'indexeur 28 et de l'entraíneur 26.However, it is unlikely that the 92 of the rotor 12 are in exact correspondence with the cavities 94 corresponding to the coach 26. In this way, the collar radial 84 finds itself in abutment axially forwards against a rear face of the notches 92, thus preventing the coach 26 to reach its engaged position. We then find ourselves in the configuration which is represented in FIG. 10, in position intermediary of indexer 28 and coach 26.

Un positionnement axial adéquat des différents éléments du verrou 10 permet d'obtenir alors d'une part l'empêchement du réembrayage complet du mécanisme si le rotor 12 est actionné à l'aide d'une clé non conforme, et d'autre part l'assurance d'un embrayage automatique du mécanisme nécessitant moins d'un demi de tour de rotation du rotor 12, en présence d'une clé conforme.Adequate axial positioning of the different elements of the lock 10 makes it possible then to obtain preventing the complete re-engagement of the mechanism if the rotor 12 is actuated using a non-conforming key, and on the other hand the assurance of an automatic clutch of the mechanism requiring less than half a turn of the rotor 12, in the presence of a conforming key.

Les valeurs de jeu et des courses qui vont être données ci-après ne le sont qu'à titre d'exemples et ne sont nullement limitatifs.The values of play and races that are going to be given below are only examples and are not in no way limiting.

On choisit par exemple un mécanisme dans lequel la course totale de l'indexeur 28 de l'entraíneur 26 entre leur position embrayée et leur position débrayée est légèrement supérieure à 3 mm. On prévoit alors que, en position embrayée, les crans 92 de la partie avant 12b du rotor 12 ne sont reçus dans les cavités 94 de l'entraíneur 26 que sur une distance axiale de l'ordre de 2 mm.We choose for example a mechanism in which the total travel of indexer 28 of coach 26 between their engaged position and their disengaged position is slightly greater than 3 mm. It is then expected that, in position engaged, the notches 92 of the front part 12b of the rotor 12 do not are received in the cavities 94 of the coach 26 only on a axial distance of the order of 2 mm.

Au contraire, lorsque l'indexeur 28 est en position de débrayage, on choisit que les doigts axiaux 100 du rotor 12 et les encoches 102 de l'indexeur 28 ne coopèrent que sur une longueur axiale de l'ordre de 1 mm.On the contrary, when the indexer 28 is in the position of declutching, we choose that the axial fingers 100 of the rotor 12 and the notches 102 of the indexer 28 cooperate only on one axial length of the order of 1 mm.

Enfin, on prévoit que les tétons 106 de l'entraíneur 26 coopèrent avec les logements 108 correspondants sur une longueur d'environ 3 mm, sensiblement égale à la course de l'entraíneur 26 mais légèrement inférieure à celle-ci.Finally, it is expected that the nipples 106 of the coach 26 cooperate with the corresponding housings 108 on a length of approximately 3 mm, substantially equal to the stroke of the coach 26 but slightly lower than this.

En adoptant de telles valeurs pour la position relative des différents éléments, on obtient que, lorsque l'indexeur 28 et l'entraíneur 26 sont en position intermédiaire, en butée contre les crans 92 du rotor 12, ceux-ci ont avancé d'une longueur légèrement supérieure à 1 mm selon la direction axiale.By adopting such values for relative position of the different elements, we get that when the indexer 28 and the coach 26 are in the intermediate position, in abutment against the notches 92 of the rotor 12, these have advanced length slightly greater than 1 mm depending on the direction axial.

Les doigts axiaux 100 du rotor 12 sont alors dégagés des encoches 102 de l'indexeur mais les tétons 106 de l'entraíneur restent bloqués à l'intérieur des logements 108.The axial fingers 100 of the rotor 12 are then released notches 102 of the indexer but the nipples 106 of the coach remain blocked inside the housing 108.

Deux cas sont alors possibles.Two cases are then possible.

Si la clé introduite dans le rotor 12 est une clé non conforme, la douille intermédiaire 16 reste solidaire du rotor 12 du fait de la présence des paillettes 32 et toute poursuite du mouvement de rotation du rotor 12 se traduit par un nouveau débrayage complet du mécanisme.If the key inserted into the rotor 12 is a key not compliant, the intermediate sleeve 16 remains integral with the rotor 12 due to the presence of the sequins 32 and any further rotational movement of rotor 12 results in a new complete disengagement of the mechanism.

Ainsi, l'indexeur 28 et l'entraíneur 26 ne reviennent pas en position complètement embrayée si la clé n'est pas conforme, ce qui permet d'éviter que le levier 24 ne soit libéré par rapport au stator 14.Thus, the indexer 28 and the coach 26 do not return not in fully engaged position if the key is not compliant, which prevents lever 24 from being released relative to stator 14.

Au contraire, si la clé introduite dans le rotor 12 est une clé conforme, le rotor 12 et la douille intermédiaire 16 se retrouvent libres l'un par rapport à l'autre en rotation mais l'entraíneur 26 reste bloqué en rotation par rapport au stator 14. Il s'ensuit qu'il est possible alors de poursuivre le mouvement de rotation du rotor 12 tout en gardant l'entraíneur 26 parfaitement immobile de sorte que les crans 92 du rotor 12 vont se déplacer par rapport au collet radial 84 de l'entraíneur 26 jusqu'à se retrouver en regard des cavités 94. En prévoyants deux crans 92 répartis à 90°, et autant de cavités 94, cette situation se produit tous les demi-tours.On the contrary, if the key inserted into the rotor 12 is a conforming key, the rotor 12 and the intermediate sleeve 16 are find themselves free relative to each other in rotation but the driver 26 remains locked in rotation relative to the stator 14. It follows that it is then possible to continue the rotational movement of rotor 12 while keeping the coach 26 perfectly stationary so that the notches 92 of the rotor 12 will move relative to the radial collar 84 of the coach 26 until it meets the cavities 94. In providing two notches 92 distributed at 90 °, and as many cavities 94, this situation occurs every U-turn.

Alors, sous l'action du ressort 30, l'entraíneur 26 peut avancer jusqu'à sa position embrayée et le rotor 12 peut alors commander la rotation du levier de commande 24.Then, under the action of the spring 30, the coach 26 can advance to its engaged position and the rotor 12 can then control the rotation of the control lever 24.

Pour leur accouplement en rotation, les parties arrière 12a et avant 12b du rotor 12 présentent des faces transversales d'extrémité, respectivement avant 112 et arrière 114, qui sont de forme complémentaire de sorte que, lorsqu'elles sont accolées axialement l'une contre l'autre, elles permettent l'entraínement en rotation de l'une des parties par l'autre.For their rotational coupling, the rear parts 12a and front 12b of the rotor 12 have faces transverse end, front 112 and rear respectively 114, which are of complementary shape so that, when they are placed axially against each other, they allow the rotation of one of the parts by the other.

Ainsi, dans l'exemple de réalisation illustré plus particulièrement sur les figures 3 et 11, la face avant 112 de la partie arrière 12a du rotor 12 présente un bossage 116 axialement en relief qui comporte une partie centrale sensiblement circulaire et deux parties radiales. Le bossage 116 est destiné à être emboíté dans un évidement complémentaire de la face arrière 114 de la partie avant 12b.Thus, in the embodiment illustrated more particularly in FIGS. 3 and 11, the front face 112 of the rear part 12a of the rotor 12 has a boss 116 axially in relief which has a central part substantially circular and two radial parts. The boss 116 is intended to be fitted into a complementary recess of the rear face 114 of the front part 12b.

Par ailleurs, on peut voir que la partie avant 12b du rotor comporte des moyens permettant d'assurer la fixation axiale de l'ensemble du mécanisme du verrou dans le stator 14. En effet, le tronçon arrière 87 est pourvu d'une gorge annulaire périphérique 118 qui débouche radialement vers l'extérieur. Comme on peut le voir sur la figure 12, la douille intermédiaire 16 comporte, sur une face cylindrique interne 120, deux nervures 122 diamétralement opposées. Les nervures 122 s'étendent chacune sur un arc de cercle d'environ 70° autour de l'axe A1, elles s'étendent radialement vers l'intérieur par rapport à la surface cylindrique 120 et elles présentent une épaisseur axiale sensiblement équivalente à la largeur axiale de la gorge annulaire 118.Furthermore, we can see that the front part 12b of the rotor includes means for securing axial of the entire lock mechanism in the stator 14. Indeed, the rear section 87 is provided with a groove peripheral ring 118 which opens radially towards outside. As can be seen in Figure 12, the socket intermediate 16 comprises, on an internal cylindrical face 120, two diametrically opposite ribs 122. The ribs 122 each extend over an arc about 70 ° around the axis A1, they extend radially inward relative to the cylindrical surface 120 and they have an axial thickness substantially equivalent to the axial width of the annular groove 118.

Pour permettre l'engagement des nervures 122 dans la gorge 118, le tronçon arrière 87 de la partie avant 12b du rotor 12 comporte deux dégagements diamétralement opposés 124, qui s'étendent angulairement sur 70° autour de l'axe A1, et qui débouchent axialement vers l'avant et vers l'arrière d'autre part dans la gorge 118. Ainsi, en mettant en correspondance angulaire les dégagements 124 de la partie avant 12b du rotor 12 avec les nervures 122 de la douille intermédiaire 16, on peut engager la partie avant 12b du rotor 12 axialement d'arrière en avant dans la douille intermédiaire 16 jusqu'à ce que les nervures 122 soient engagées dans la gorge 118. Ensuite, par une simple rotation de la partie avant 12b du rotor 12 autour de l'axe A1, on obtient une fixation axiale de celle-ci par rapport à la douille intermédiaire.To allow engagement of the ribs 122 in the groove 118, the rear section 87 of the front part 12b of the rotor 12 has two diametrically opposite clearances 124, which extend angularly over 70 ° around the axis A1, and which open axially forwards and backwards on the other hand in the throat 118. So, by putting in angular correspondence the clearances 124 of the part front 12b of the rotor 12 with the ribs 122 of the sleeve intermediate 16, the front part 12b of the rotor can be engaged 12 axially from back to front in the intermediate sleeve 16 until the ribs 122 are engaged in the throat 118. Then, by a simple rotation of the front part 12b of the rotor 12 around the axis A1, a fixing is obtained axial of the latter relative to the intermediate sleeve.

Par ailleurs, on peut voir que le tronçon d'extrémité avant 90 de la partie avant 12b du rotor 12 présente une gorge annulaire 126 qui est agencée axialement en avant des crans 92. Comme on peut le voir par exemple sur la figure 13, la gorge 126 est destinée à recevoir un anneau élastique fendu 128 qui permet d'immobiliser axialement vers l'arrière le levier de commande 24 par rapport à la partie avant 12b du rotor 12. Comme par ailleurs le levier de commande 24 est destiné à venir en appui par sa périphérie circulaire axialement vers l'arrière contre le stator 14, on voit que la partie avant 12b du rotor 12 ne peut être déplacée axialement vers l'arrière par rapport au stator 14.Furthermore, we can see that the end section front 90 of the front part 12b of the rotor 12 has a groove annular 126 which is arranged axially in front of the notches 92. As can be seen for example in Figure 13, the groove 126 is intended to receive a split elastic ring 128 which makes it possible to immobilize the lever axially towards the rear control 24 relative to the front part 12b of the rotor 12. As also the control lever 24 is intended to abut by its circular periphery axially towards the rear against the stator 14, we see that the front part 12b of the rotor 12 cannot be moved axially backwards by stator report 14.

Par ailleurs, comme on peut le voir par exemple sur la figure 13, la douille intermédiaire 16 est en appui axialement vers l'avant contre la face annulaire périphérique 58 du stator 14 de telle sorte que la partie avant 12b du rotor 12 se trouve donc immobilisée axialement vers l'avant par rapport au stator 14.Furthermore, as can be seen for example on the Figure 13, the intermediate sleeve 16 is axially supported forwardly against the peripheral annular face 58 of the stator 14 such that the front part 12b of the rotor 12 is located therefore immobilized axially towards the front relative to the stator 14.

La partie avant 12b du rotor 12, qui porte les moyens de débrayage du verrou 10, est donc immobilisée axialement dans les deux sens par rapport au stator 14.The front part 12b of the rotor 12, which carries the means for disengaging the lock 10, is therefore immobilized axially in both directions with respect to the stator 14.

Ainsi, on peut donc voir que l'ensemble de la douille intermédiaire, de la partie avant 12b du rotor 12 et du levier de commande est ainsi immobilisé axialement par rapport au stator 14, indépendamment de la présence de la partie arrière 12a du rotor 12. Seul l'entraíneur 26 et son indexeur 28 peuvent coulisser axialement, sur une course limitée, par rapport au stator 14.So, we can see that the entire socket intermediate, the front part 12b of the rotor 12 and the lever control is thus immobilized axially relative to the stator 14, regardless of the presence of the rear part 12a of the rotor 12. Only the driver 26 and its indexer 28 can slide axially, over a limited stroke, by stator report 14.

La partie arrière 12a du rotor 12 présente essentiellement un tronçon avant 86, de même diamètre que le tronçon arrière 87 de la partie avant 12b, et un tronçon arrière 132 de diamètre supérieur.The rear part 12a of the rotor 12 has essentially a front section 86, of the same diameter as the section rear 87 of the front part 12b, and a rear section 132 of upper diameter.

A l'extrémité avant de son tronçon 132, la partie arrière 12a du rotor 12 comporte une gorge annulaire 134 agencée juste en arrière d'une surface tronconique 136 d'axe A1 effilée vers l'avant qui permet d'écarter radialement vers l'extérieur les branches 138 d'une goupille 140 qui est destinée à être engagée transversalement dans l'extrémité arrière du stator 14 de telle sorte que les branches 138 s'étendent selon une corde en travers de l'alésage délimité par le stator 14. Ainsi, lorsque la partie arrière 12a du rotor 12 est engagée axialement d'arrière en avant dans le stator 14, son tronçon avant 86 étant guidé dans la douille intermédiaire 16, il est susceptible d'être amené axialement jusqu'à une position de contact des branches 138 de la goupille 140 avec la surface tronconique 136. En poursuivant le mouvement vers l'avant, cette dernière surface tronconique 136 écarte les branches 138, lesquelles retombent ensuite de manière élastique à l'intérieur de la gorge 134 pour immobiliser axialement la partie arrière 12a du rotor 12 par rapport au stator 14 par simple encliquetage.At the front end of its section 132, the part rear 12a of the rotor 12 has an annular groove 134 arranged just behind a frusto-conical surface 136 of axis A1 tapered forwards which allows to spread radially towards outside the branches 138 of a pin 140 which is intended to be engaged transversely in the end rear of stator 14 so that the legs 138 extend along a cord across the bore delimited by the stator 14. Thus, when the rear part 12a of the rotor 12 is axially engaged from back to front in stator 14, its front section 86 being guided in the intermediate sleeve 16, it is capable of being brought axially to a position of contact of the branches 138 of the pin 140 with the surface tapered 136. Continuing the forward movement, this last frustoconical surface 136 spreads the branches 138, which then fall back elastically at inside the groove 134 for axially immobilizing the rear part 12a of the rotor 12 relative to the stator 14 by simple snap-in.

Bien entendu, on veille, lors de l'introduction de la partie arrière 12b du rotor 12, à indexer celle-ci angulairement par rapport à la partie avant 12a de telle sorte que leurs faces transversales complémentaires 112, 114 se présentent l'une en regard de l'autre dans une position permettant leur accouplement. Of course, care is taken when introducing the rear part 12b of the rotor 12, to index it angularly relative to the front part 12a so that their faces complementary transverse 112, 114 are one facing each other in a position allowing their coupling.

Conformément aux enseignements de l'invention, le verrou 10 qui vient d'être décrit est particulièrement avantageux en ce qu'il peut être monté en deux temps. Dans un premier temps, l'ensemble des pièces comportant notamment la partie avant 12b du rotor 12, l'indexeur 28 et l'entraíneur 26, la douille intermédiaire 16, le ressort 30 et le levier de commande 24 peut être monté sur le stator 14. Lorsque celui-ci est fixé sur le véhicule, le verrou peut donc être relié à la serrure de l'ouvrant. On peut, à ce stade des opérations, vérifier le bon fonctionnement de l'assemblage ainsi réalisé par exemple en manipulant la partie avant 12b du rotor à l'aide d'un outil présentant une face transversale avant complémentaire de la face transversale arrière 114 de la partie avant 12a du rotor 12.In accordance with the teachings of the invention, the lock 10 which has just been described is particularly advantageous in that it can be mounted in two stages. In firstly, all the parts comprising in particular the front part 12b of the rotor 12, the indexer 28 and the driver 26, the intermediate sleeve 16, the spring 30 and the control lever 24 can be mounted on the stator 14. When this is attached to the vehicle, the lock can therefore be connected to the door lock. At this stage we can operations, check the proper functioning of the assembly thus produced for example by manipulating the front part 12b of the rotor using a tool with a transverse front face complementary to the rear transverse face 114 of the part front 12a of rotor 12.

Ensuite, à un stade ultérieur de l'assemblage du véhicule, voire même au moment des ultimes étapes de préparation de celui-ci, il est possible de terminer l'assemblage du verrou après que la partie pré-assemblée de celui-ci ait été montée sur le véhicule, en engageant la partie arrière 12a du rotor 12 dans le stator 14 au travers d'une ouverture de la carrosserie de l'ouvrant du véhicule dont le diamètre n'excède pas celui du tronçon arrière 132, qui sera par exemple sensiblement égal à celui de la douille 16.Then at a later stage of assembling the vehicle, or even at the final stages of preparation of it it is possible to finish assembling the lock after the pre-assembled part of this has been mounted on the vehicle, engaging the part rear 12a of the rotor 12 in the stator 14 through a opening of the body of the door of the vehicle, the diameter does not exceed that of the rear section 132, which will be for example substantially equal to that of the socket 16.

Ainsi, en séparant le rotor 12 en deux parties 12a, 12b dont une porte les éléments mécaniques permettant de réaliser notamment le débrayage, et d'autre part une partie qui porte les éléments de codage, à savoir les paillettes 32, qui permettent d'individualiser le verrou 10, on peut se contenter d'attribuer une clef à un véhicule à un moment très tardif de la production de celui-ci.Thus, by separating the rotor 12 into two parts 12a, 12b, one of which carries the mechanical elements allowing release in particular, and on the other hand a part which carries the coding elements, namely the sequins 32, which allow to individualize the lock 10, we can be satisfied to assign a key to a vehicle at a very late time in the production of it.
