Description

L'invention est relative à un verrou du genre de ceux qui comprennent un stator, un rotor monté libre en rotation dans le stator, un organe tel qu'une batteuse prévu vers une extrémité du rotor et un pêne propre à passer d'une position effacée à une position active pour assurer l'entraînement en rotation de la batteuse par le rotor, ce rotor comportant un logement s'ouvrant à l'extrémité opposée à la batteuse et propre à recevoir une clé, des organes de sélection étant disposés radialement à la paroi du rotor et débouchant dans le logement de manière à coopérer avec la clé de sorte que lorsqu'une clé conforme a été convenablement introduite dans le logement du rotor, les organes de sélection soient placés dans une position permettant le déplacement du pêne vers sa position active et l'entrainement de la batteuse.The invention relates to a lock of the type which includes a stator, a rotor mounted to rotate freely in the stator, a member such as a thresher provided towards one end of the rotor and a bolt suitable for passing from a position. cleared to an active position to ensure the rotation of the thresher by the rotor, this rotor comprising a housing opening at the end opposite the thresher and suitable for receiving a key, selection members being arranged radially the wall of the rotor and opening into the housing so as to cooperate with the key so that when a conforming key has been properly inserted into the housing of the rotor, the selection members are placed in a position allowing the bolt to move towards its active position and thresher drive.

En général, la batteuse sert à commander un mécanisme de serrure.In general, the thresher is used to control a lock mechanism.

Un tel verrou présente l'avantage d'être débrayable, c'est-à-dire que lors d'une tentative d'effraction par exemple à l'aide d'une clé non conforme ou d'une lame de tournevis introduite dans le logement du rotor, de manière à exercer un couple de rotation sur ce rotor, ce dernier va tourner librement dans le stator, sans entraîner la batteuse, et sans provoquer la détérioration des organes de sélection. La commande de la serrure ne sera donc pas assurée et le verrou ne sera pas détruit.Such a lock has the advantage of being disengageable, that is to say that during an attempted break-in, for example using a non-conforming key or a screwdriver blade inserted in the housing of the rotor, so as to exert a torque on this rotor, the latter will rotate freely in the stator, without driving the thresher, and without causing deterioration of the selection members. The control of the lock will therefore not be ensured and the lock will not be destroyed.

Des verrous de ce type sont connus, notamment par FR-A-2 579 655. Selon ce document, une pièce, formant pêne, est montée dans le rotor, et les organes de sélection sont disposés dans cette pièce et à l'intérieur du rotor ; le coulissement de la pièce pour établir la liaison en rotation entre le rotor et la batteuse est obtenu par l'action de la pression de la pointe de la clé, introduite dans le logement du rotor, et venant en appui contre une butée de la pièce.Locks of this type are known, in particular from FR-A-2 579 655. According to this document, a part, forming a bolt, is mounted in the rotor, and the selection members are arranged in this part and inside the rotor; the sliding of the part to establish the connection in rotation between the rotor and the threshing machine is obtained by the action of the pressure of the tip of the key, introduced into the housing of the rotor, and coming to bear against a stop of the part.

La réalisation du rotor pour un tel verrou est relativement délicate et les opérations d'assemblage des différents éléments disposés dans le rotor, coopérant avec la pièce formant pêne, sont relativement compliquées. En outre, la pièce formant pêne est accessible depuis le logement prévu pour la clé-dans le rotor ce qui facilite une effraction par poussée sur cette pièce suivant une direction parallèle à l'axe du rotor.The realization of the rotor for such a lock is relatively delicate and the operations of assembling the different elements arranged in the rotor, cooperating with the bolt-forming part, are relatively complicated. In addition, the bolt-forming part is accessible from the housing provided for the key in the rotor, which facilitates break-in by pushing on this part in a direction parallel to the axis of the rotor.

L'invention a pour but, surtout, de fournir un verrou du genre défini précédemment, qui ne présente plus, ou à un degré moindre, les inconvénients évoqués ci-dessus. On souhaite, en particulier, que la réalisation du rotor soit simplifiée et que le pêne soit le moins accessible possible depuis l'extérieur du verrou.The invention aims, above all, to provide a lock of the kind defined above, which no longer has, or to a lesser degree, the drawbacks mentioned above. In particular, it is desired that the production of the rotor be simplified and that the bolt be as less accessible as possible from outside the lock.

Selon l'invention, le verrou comprend un stator, un rotor monté libre en rotation dans le stator, un organe tel qu'une batteuse prévu vers une extrémité du rotor et un pêne propre à passer d'une position effacée à une position active pour assurer l'entraînement en rotation de la batteuse par le rotor, le rotor comportant un logement s'ouvrant à l'extrémité opposée à la batteuse et propre à recevoir une clé, des organes de sélection étant prévus pour traverser radialement la paroi du rotor et déboucher dans le logement de manière à coopérer avec la clé de sorte que lorsqu'une clé conforme a été convenablement introduite dans le logement du rotor, les organes de sélection soient placés dans une position permettant le déplacement du pêne vers sa position active et l'entraînement de la batteuse,

  • le pêne étant situé à l'extérieur du logement prévu dans le rotor pour la clé,
  • des moyens de déplacement du pêne étant prévus à l'extérieur du rotor, et propres à déplacer le pêne, lorsqu'une clé conforme a été introduite, vers une position active entre le rotor et la batteuse,
  • des moyens étant en outre prévus pour ramener le pêne dans sa position effacée lors du retrait de la clé,
  • ledit verrou étant caractérisé par le fait que le pêne est basculant et est constitué par une pièce s'étendant selon la longueur du rotor, cette pièce étant articulée sur un axe longitudinal parallèle à l'axe du rotor et porté extérieurement par ce rotor, le pêne comportant un moyen d'entraînement propre à coopérer avec un moyen complémentaire de la batteuse lorsqu'une clé conforme a été introduite, et que le pêne a basculé, pour l'entraînement en rotation de la batteuse.
According to the invention, the lock comprises a stator, a rotor mounted to rotate freely in the stator, a member such as a threshing machine provided towards one end of the rotor and a bolt suitable for passing from an erased position to an active position for ensure the rotation of the thresher by the rotor, the rotor comprising a housing opening at the end opposite the thresher and suitable for receiving a key, selection members being provided for radially passing through the wall of the rotor and open into the housing so as to cooperate with the key so that when a conforming key has been properly inserted into the housing of the rotor, the selection members are placed in a position allowing the bolt to move towards its active position and the thresher drive,
  • the bolt being located outside the housing provided in the rotor for the key,
  • means for moving the bolt being provided outside the rotor, and suitable for moving the bolt, when a conforming key has been inserted, towards an active position between the rotor and the thresher,
  • means being further provided for returning the bolt to its erased position when the key is removed,
  • said lock being characterized by the fact that the bolt is tilting and is constituted by a part extending along the length of the rotor, this part being articulated on a longitudinal axis parallel to the axis of the rotor and carried externally by this rotor, the bolt comprising a drive means suitable for cooperating with a means complementary to the threshing device when a conforming key has been introduced, and the bolt has tilted, for driving the threshing machine in rotation.

Le moyen d'entraînement peut comprendre un ergot situé en bout du pêne, orienté parallèlement à l'axe du rotor, et propre à entrer dans une encoche radiale intérieure lorsque le pêne bascule vers l'intérieur en réponse à une disposition appropriée des organes de sélection.The drive means may comprise a lug located at the end of the bolt, oriented parallel to the axis of the rotor, and suitable for entering an internal radial notch when the bolt swivels inward in response to an appropriate arrangement of the selection.

Avantageusement, le verrou comporte, pour la batteuse, un pion de condamnation mobile radialement, muni d'une rainure, le pion de condamnation étant poussé par un ressort.Advantageously, the lock comprises, for the thresher, a radially movable locking pin, provided with a groove, the locking pin being pushed by a spring.

De préférence, les organes de sélection sont constitués par des paillettes dont le plan moyen est orthogonal à l'axe du rotor, ces paillettes étant montées avec possibilité de coulissement radial dans le rotor, chaque paillette comportant au moins une encoche sur un bord longitudinal, ces encoches étant propres à s'aligner lorsqu'une clé conforme a été introduite dans le rotor, ce dernier comportant une fenêtre propre à permettre l'entrée d'un bec du pêne basculant, l'ensemble étant tel que lorsque les encoches ont été alignées par l'introduction d'une clé conforme, le bec du pêne peut entrer dans ces encoches, ce qui permet le basculement radial du pêne et l'entraînement de la batteuse par le rotor.Preferably, the selection members consist of flakes whose mean plane is orthogonal to the axis of the rotor, these flakes being mounted with the possibility of radial sliding in the rotor, each flake comprising at least one notch on a longitudinal edge, these notches being able to align when a conforming key has been introduced into the rotor, the latter comprising a window suitable for allowing the entry of a tilting latch beak, the assembly being such that when the notches have been aligned by the introduction of a conforming key, the latch beak can enter these notches, which allows the radial tilting of the bolt and the driving of the thresher by the rotor.

L'encoche radiale intérieure peut être prévue en bordure d'une gorge circulaire de la batteuse dans laquelle peut s'engager ledit ergot.The internal radial notch can be provided at the edge of a circular groove of the thresher in which said lug can engage.

La rainure du pion de condamnation est propre à recevoir l'extrémité de l'ergot.The groove of the locking pin is adapted to receive the end of the lug.

Selon une variante de réalisation de la présente invention, l'encoche radiale intérieure est prévue dans le fond d'un évidement de la paroi cylindrique du rotor, la profondeur de cet évidement étant au moins égale au diamètre de l'ergot du pêne.According to an alternative embodiment of the present invention, the internal radial notch is provided in the bottom of a recess in the cylindrical wall of the rotor, the depth of this recess being at least equal to the diameter of the lug of the bolt.

De préférence, l'encoche radiale a une forme concave semi-circulaire.Preferably, the radial notch has a semi-circular concave shape.

Le pion de condamnation de la batteuse prend appui contre l'ergot du pêne et est propre à entrer, par une extrémité, dans l'évidement du rotor pour contribuer à l'entraînement en rotation de la batteuse par le rotor, la rainure pouvant recevoir la paroi de bout du stator.The threshing latch pin bears against the lug of the bolt and is suitable for entering, at one end, into the recess of the rotor to contribute to the rotary drive of the thresher by the rotor, the groove being able to receive the end wall of the stator.

Le verrou est agencé pour que la rotation du rotor, alors que le pêne est en position effacée, provoque l'écartement du pion de condamnation qui sort de l'évidement et prend appui contre la surface extérieure du rotor.The lock is arranged so that the rotation of the rotor, while the bolt is in the erased position, causes the spacing of the locking pin which comes out of the recess and bears against the outer surface of the rotor.

Un verrou conforme à l'invention convient aussi bien pour des serrures destinées à l'industrie automobile, qu'à des serrures destinés au bâtiment.A lock according to the invention is suitable for locks intended for the automotive industry as well as for locks intended for the building industry.

En se reportant aux figures des dessins, on peut voir un verrou 301 comprenant un stator 302 et un rotor 303 monté libre en rotation dans le stator, mais immobilisé en translation.Referring to the figures of the drawings, one can see a lock 301 comprising a stator 302 and a rotor 303 mounted freely in rotation in the stator, but immobilized in translation.

Un organe formé par une batteuse 304 est prévu vers une extrémité du rotor 303. La batteuse 304 est montée libre en rotation sur un prolongement 305 du rotor. Une liaison en rotation peut être établie entre la batteuse 304 et le rotor 303 par un pêne 306 propre à passer d'une position effacée, représentée sur la figure 1, à une position active, représentée sur la figure 3 lorsqu'une clé conforme 307 a été introduite dans un logement 308 du rotor 303, ce logement s'ouvrant à l'extrémité du rotor opposée à la batteuse.A member formed by a thresher 304 is provided towards one end of the rotor 303. The thresher 304 is mounted to rotate freely on an extension 305 of the rotor. A rotational connection can be established between the thresher 304 and the rotor 303 by a bolt 306 suitable for passing from an erased position, represented in FIG. 1, to an active position, represented in FIG. 3 when a conforming key 307 has been introduced into a housing 308 of the rotor 303, this housing opening at the end of the rotor opposite the threshing machine.

Des organes de sélection 309 constitués par des paillettes sont disposés radialement à la paroi cylindrique du rotor 303. Lorsqu'une clé conforme 307 est introduite (fig. 3 et 4), les organes de sélection 309 sont placés dans une position permettant le déplacement du pêne 306 vers sa position active et l'entraînement de la batteuse par le rotor.Selection members 309 constituted by flakes are arranged radially to the cylindrical wall of the rotor 303. When a conforming key 307 is introduced (fig. 3 and 4), the selection members 309 are placed in a position allowing the movement of the bolt 306 to its active position and the thresher drive by the rotor.

Le pêne 306 est basculant et est constitué par une pièce (voir figure 7) d'allure cylindrique dont les génératrices sont orientées parallèlement à l'axe du rotor 303. La section transversale de ce pêne 306 a sensiblement la forme d'un arc de couronne circulaire dont le rayon du bord extérieur est sensiblement égal au rayon extérieur du rotor 303 ; à une extrémité de cette section transversale, située sur la droite des figures 1 et 3, le pêne 306 comporte une tête 59 de plus grande dimension suivant la direction radiale, faisant saillie vers l'intérieur par un bec 60, et, vers l'extérieur, par une partie arrondie 61. A son extrémité tournée vers la batteuse, le pêne 306 porte, dans cette partie 61, un doigt cylindrique 62 faisant saillie relativement à la face transversale du pêne, parallèlement aux génératrices.The bolt 306 is tiltable and is constituted by a part (see FIG. 7) of cylindrical appearance whose generatrices are oriented parallel to the axis of the rotor 303. The cross section of this bolt 306 has substantially the shape of an arc of circular crown whose radius of the outer edge is substantially equal to the outer radius of the rotor 303; at one end of this cross section, situated on the right of FIGS. 1 and 3, the bolt 306 comprises a head 59 of larger dimension in the radial direction, projecting inwards by a spout 60, and, towards the outside, by a rounded part 61. At its end facing the threshing machine, the bolt 306 carries, in this part 61, a cylindrical finger 62 projecting relative to the transverse face of the bolt, parallel to the generatrices.

Le bord longitudinal du pêne 306 opposé à la tête 59 comporte deux échancrures 63, voisines de chacune des extrémités longitudinales du pêne. Un alésage est prévu, dans ce bord, parallèlement aux génératrices du pêne, sur toute la longueur de manière à traverser les deux échancrures 63. Cet alésage est propre à recevoir un axe d'articulation 64 formé par une tige cylindrique.The longitudinal edge of the bolt 306 opposite the head 59 has two notches 63, adjacent to each of the longitudinal ends of the bolt. A bore is provided in this edge, parallel to the generatrices of the bolt, over the entire length so as to pass through the two notches 63. This bore is suitable for receiving a hinge pin 64 formed by a cylindrical rod.

Le rotor 303 comporte, sur sa paroi extérieure, un évidement 65 propre à recevoir la majeure partie du pêne 306. Deux paliers 66 sont prévus dans cet évidement 65 pour venir se loger dans les échancrures 63, ces paliers comportant des alésages pour le passage de la tige 64.The rotor 303 has, on its outer wall, a recess 65 suitable for receiving the major part of the bolt 306. Two bearings 66 are provided in this recess 65 to be accommodated in the notches 63, these bearings comprising bores for the passage of the rod 64.

Le doigt ou ergot 62 est propre à être engagé dans une gorge circulaire 67 prévue sur la batteuse 304 et centrée sur l'axe du rotor 303. Le rayon de cette gorge 67 est déterminé de manière telle que, lorsque le doigt 62 est engagé dans cette gorge, le pêne 306 est maintenu dans une position relevée vis-à-vis du rotor 303, comme représenté sur la figure 1, le bec 60 étant écarté des paillettes 309.The finger or lug 62 is suitable for being engaged in a circular groove 67 provided on the threshing machine 304 and centered on the axis of the rotor 303. The radius of this groove 67 is determined so that, when the finger 62 is engaged in this groove, the bolt 306 is held in a raised position with respect to the rotor 303, as shown in FIG. 1, the spout 60 being spaced apart from the flakes 309.

Une encoche radiale 68 est prévue sur la bordure intérieure de la gorge 67, pour recevoir le doigt 62 et permettre ainsi le basculement, radialement vers l'intérieur, dans le sens d'horloge selon la représentation des figures 1 et 3, du pêne 306.A radial notch 68 is provided on the inner edge of the groove 67, to receive the finger 62 and thus allow the tilting, radially inward, in the clockwise direction as shown in Figures 1 and 3, of the bolt 306 .

Le rotor 303 comporte une fenêtre longitudinale 69 communiquant avec les logements dans lesquels peuvent glisser les paillettes 309 constituant les organes de sélection.The rotor 303 has a longitudinal window 69 communicating with the housings in which the flakes 309 constituting the selection members can slide.

Chaque paillette 309 comporte, sur son bord longitudinal tourné vers le pêne 306, une encoche 70 propre à recevoir la zone longitudinale correspondante du bec 60.Each straw 309 has, on its longitudinal edge facing the latch 306, a notch 70 adapted to receive the corresponding longitudinal area of the spout 60.

Des moyens élastiques 74 (voir figure 5) sont prévus pour solliciter le pêne en rotation vers l'intérieur du rotor 303, c'est-à-dire dans le sens d'horloge autour de la tige 64 selon la représentation des figures 1 et 3. Les encoches 70 sont disposées de telle sorte que, lorsqu'une clé conforme a été introduite dans le logement du rotor 303, les encoches 70 sont alignées suivant une direction parallèle à l'axe du rotor et se trouvent au droit du bec 60 pour le recevoir.Elastic means 74 (see FIG. 5) are provided to urge the bolt in rotation towards the inside of the rotor 303, that is to say in the clockwise direction around the rod 64 according to the representation of FIGS. 1 and 3. The notches 70 are arranged in such a way so that, when a conforming key has been inserted into the housing of the rotor 303, the notches 70 are aligned in a direction parallel to the axis of the rotor and are located in line with the spout 60 to receive it.

L'indexation de la position de la batteuse 304 par rapport au stator 302 (voir figure 5) en position de repos ou position zéro est obtenue à l'aide d'un pion de condamnation 354 mobile radialement dans une rainure 71 prévue dans la batteuse et qui communique avec une zone de la gorge 67, du côté opposé au rotor 303.Indexing of the position of the thresher 304 relative to the stator 302 (see FIG. 5) in the rest position or zero position is obtained using a locking pin 354 movable radially in a groove 71 provided in the thresher and which communicates with a region of the groove 67, on the side opposite to the rotor 303.

Le pion 354 comporte une rainure sensiblement en arc de cercle 72 propre à être placée en face de la zone correspondante de la gorge 67 afin de recevoir l'extrémité du doigt 62. Les dimensions des pièces sont telles que lorsque le doigt 62 est engagé dans la gorge 67, l'extrémité radiale extérieure du pion 354 fait saillie au-delà du contour extérieur de la batteuse 304 et est engagée dans un logement 358 prévu sur le stator 302. Un poussoir 73 est disposé dans ce logement 358 et est poussé par un ressort de compression 74 qui sollicite donc le pêne 306 au basculement vers l'intérieur.The pin 354 has a groove substantially in an arc 72 suitable for being placed opposite the corresponding region of the groove 67 in order to receive the end of the finger 62. The dimensions of the parts are such that when the finger 62 is engaged in the groove 67, the outer radial end of the pin 354 protrudes beyond the outer contour of the threshing machine 304 and is engaged in a housing 358 provided on the stator 302. A pusher 73 is disposed in this housing 358 and is pushed by a compression spring 74 which therefore urges the bolt 306 to tilt inward.

Ceci étant, le fonctionnement du verrou des figures 1 à 7 est le suivant.That said, the operation of the lock of Figures 1 to 7 is as follows.

Lorsqu'une clé conforme 307 est introduite dans le rotor, les crans ou encoches 70 des paillettes 309 s'alignent et le pêne 306 peut basculer vers l'intérieur, son bec 60 venant se loger dans les encoches 70, tandis que le doigt 62 entre dans l'encoche 68. Ce mouvement du pêne est aidé par le ressort 74 qui fait coulisser, vers le centre, le pion 354 dans la rainure 71. Lorsque le pêne occupe la position de la figure 3, la face de séparation entre le pion 354 et le poussoir 73 se trouve sur la surface cylindrique de contact entre la batteuse 304 et le stator 302 de sorte que la batteuse peut tourner relativement au stator en entraînant le pion 354.When a conforming key 307 is introduced into the rotor, the notches or notches 70 of the flakes 309 align and the bolt 306 can tilt inwards, its beak 60 coming to be housed in the notches 70, while the finger 62 enters notch 68. This movement of the bolt is helped by the spring 74 which slides, towards the center, the pin 354 in the groove 71. When the bolt occupies the position of FIG. 3, the separation face between the pin 354 and the pusher 73 is on the cylindrical surface of contact between the thresher 304 and the stator 302 so that the thresher can rotate relative to the stator by driving the pin 354.

Ce mouvement de rotation de la batteuse est obtenu en exerçant un couple approprié sur la clé conforme introduite dans le rotor, ce qui permet de commander la serrure.This rotary movement of the thresher is obtained by exerting an appropriate torque on the conforming key introduced into the rotor, which makes it possible to control the lock.

Le retour à zéro est assuré par le ressort 329. Après retrait de la clé, le pêne 306 se soulève, sous l'action des paillettes 309 repoussées vers l'extérieur par les ressorts correspondants. On retrouve la position de la figure 1.The return to zero is ensured by the spring 329. After removal of the key, the bolt 306 is raised, under the action of the flakes 309 pushed outwards by the corresponding springs. We find the position of figure 1.

Si une clé non conforme, ou une lame d'outil, est introduite dans le rotor en vue d'une effraction, au moins l'une des paillettes 309 ne viendra pas en alignement, au niveau de son encoche, avec les autres paillettes, de sorte que le bec 60 du pêne reste en appui sur le côté de cette paillette dans la position relevée de la figure 1. Le pion 62 reste dans la gorge 67.If a non-conforming key, or a tool blade, is inserted into the rotor for burglary, at least one of the flakes 309 will not come into alignment, at its notch, with the other flakes, so that the spout 60 of the bolt remains in abutment on the side of this straw in the raised position of FIG. 1. The pin 62 remains in the groove 67.

Le rotor 303 est libre en rotation et peut tourner, sous l'effet d'un couple, le doigt 62 se déplaçant dans la gorge 67, sans entraîner la batteuse.The rotor 303 is free to rotate and can rotate, under the effect of a torque, the finger 62 moving in the groove 67, without driving the thresher.

Les moyens de retrait du pêne 306 dans sa position effacée (relevée) de la figure 1 sont formés par les surfaces inclinées conjuguées 70a, 60a des encoches 70 et du bec 60, combinées avec les ressorts e.The means for withdrawal of the bolt 306 in its retracted position (raised) of Figure 1 are formed by the sloping surfaces 70 has conjugated, 60 has notches 70 and spout 60, combined with an springs.

La clé utilisée pour le verrou des figures 1 à 7 est une clé plate.The key used for the lock of Figures 1 to 7 is a flat key.

En se reportant aux figures 8 à 12, on peut voir une variante de réalisation avantageuse d'un verrou selon l'invention.Referring to Figures 8 to 12, we can see an advantageous alternative embodiment of a lock according to the invention.

Les éléments de ce verrou identiques à des éléments déjà décrits à propos des figures précédentes sont désignés par les mêmes références numériques, leur description n'étant pas reprise ou n'étant effectuée que succinctement. Les éléments de ces figures 8 à 12 ayant subi quelques modifications relativement aux figures précédentes, mais dont les fonctions peuvent être comparées à celles d'éléments de ces figures précédentes sont désignés par des références numériques ayant les mêmes chiffres des dizaines et des unités mais dont le chiffre des centaines est quatre, au lieu de trois sur les figures précédentes.The elements of this lock identical to elements already described in connection with the preceding figures are designated by the same reference numerals, their description not being repeated or being carried out only succinctly. The elements of these figures 8 to 12 having undergone some modifications relative to the previous figures, but whose functions can be compared to those of elements of these previous figures are designated by numerical references having the same digits of tens and units but of which the hundreds figure is four, instead of three in the previous figures.

Le pêne 406 est toujours un pêne basculant dont l'articulation autour de l'axe longitudinal géométrique 64 est obtenue à l'aide de pions cylindriques tels que 75, coaxiaux à l'axe géométrique de rotation, et en saillie longitudinale sur chaque face transversale d'extrémité du pêne 406. Chaque pion 75 est reçu dans un logement 76 prévu dans le rotor 403 (voir figures 9 et 12). Ce logement 76 est délimité, vers l'intérieur, par des sortes de dents 77 qui s'engagent dans des ouvertures 78 prévues dans la paroi radiale du pêne 406. Le guidage en rotation du pêne est ainsi assuré, avec maintien suivant la direction longitudinale par coopération des dents 77 et des parois des ouvertures 78.The bolt 406 is always a tilting bolt whose articulation around the geometric longitudinal axis 64 is obtained using cylindrical pins such as 75, coaxial with the geometric axis of rotation, and projecting longitudinally on each transverse face end of the bolt 406. Each pin 75 is received in a housing 76 provided in the rotor 403 (see Figures 9 and 12). This housing 76 is delimited, inwards, by kinds of teeth 77 which engage in openings 78 provided in the radial wall of the bolt 406. The rotary guide of the bolt is thus ensured, with maintenance in the longitudinal direction by cooperation of the teeth 77 and the walls of the openings 78.

Le rotor 403 comporte, vers son extrémité voisine de la batteuse 404, un évidement 79, de section transversale sensiblement rectangulaire, s'ouvrant sur sa surface cylindrique. La profondeur, c'est-à-dire la dimension radiale, de cet évidement 79 est au moins égale au diamètre de l'ergot 62 du pêne 406. Lorsque le pêne est en position effacée, comme illustré sur la figure 9, l'ergot 62 est engagé dans l'évidement 79 et est situé radialement à l'intérieur du prolongement virtuel de la surface cylindrique du rotor 403 au niveau de l'évidement 79. La largeur périphérique de cet évidement 79 est supérieure au diamètre de l'ergot 62 de manière à pouvoir recevoir l'extrémité radiale intérieure 80 du poussoir 454 de la batteuse. Ce poussoir traverse une échancrure 81 prévue en bout du stator 402.The rotor 403 comprises, towards its end near the thresher 404, a recess 79, of substantially rectangular cross section, opening on its cylindrical surface. The depth, that is to say the radial dimension, of this recess 79 is at least equal to the diameter of the lug 62 of the bolt 406. When the bolt is in the retracted position, as illustrated in FIG. 9, the lug 62 is engaged in the recess 79 and is located radially inside the virtual extension of the cylindrical surface of the rotor 403 at the level of the recess 79. The peripheral width of this recess 79 is greater than the diameter of the lug 62 so as to be able to receive the inner radial end 80 of the plunger 454 of the thresher. This pusher passes through a notch 81 provided at the end of the stator 402.

Le fond de l'évidement 79 comporte une encoche radiale 468 qui a une forme concave semi-circulaire. Lorsqu'une clé conforme 407 (voir figure 12) a été introduite dans les ouvertures 308 des paillettes 309, les encoches 70 sont alignées et le pêne 406 peut basculer. L'ergot 62 peut alors entrer dans l'encoche 468 ce qui permet au poussoir 454 de se déplacer radialement vers l'intérieur sous l'action du ressort 74.The bottom of the recess 79 has a radial notch 468 which has a concave semi-circular shape. When a conforming key 407 (see FIG. 12) has been introduced into the openings 308 of the flakes 309, the notches 70 are aligned and the bolt 406 can tilt. The lug 62 can then enter the notch 468 which allows the pusher 454 to move radially inwards under the action of the spring 74.

Ce poussoir 454 comporte une rainure 472 qui, lorsque le pêne occupe sa position active de la figure 12, vient se placer au droit de la paroi du stator 402. Il est alors possible à la batteuse 404 d'être entraînée en rotation par le rotor 403 car le pion 454 ne la bloque plus en rotation relativement au stator puisque la paroi de ce stator 402, limitant l'échancrure 81, peut s'engager dans la rainure 472 suffisamment large pour cela.This pusher 454 has a groove 472 which, when the bolt occupies its active position in FIG. 12, is placed in line with the wall of the stator 402. It is then possible for the thresher 404 to be rotated by the rotor 403 because the pin 454 no longer blocks it in rotation relative to the stator since the wall of this stator 402, limiting the notch 81, can engage in the groove 472 wide enough for this.

Il est à noter que la paroi radiale intérieure de l'extrémité 80 a une forme concave épousant la surface de l'ergot 62.It should be noted that the inner radial wall of the end 80 has a concave shape matching the surface of the lug 62.

Lorsque le pêne 406 est dans la position effacée des figures 8 et 9, aucune liaison en rotation n'est établie entre le rotor 403 et la batteuse 404 qui est bloquée en rotation relativement au stator 402 par le poussoir 454.When the bolt 406 is in the retracted position of FIGS. 8 and 9, no rotational connection is established between the rotor 403 and the thresher 404 which is locked in rotation relative to the stator 402 by the pusher 454.

Si une rotation du rotor 403 est provoquée, à partir de la position de la figure 8, le poussoir 454 est légèrement repoussé radialement par l'ergot 62, lorsque le rotor amorce sa rotation autour de son axe. La surface extérieure cylindrique du rotor 403, en bordure de l'évidement 79, va s'engager sous le poussoir 454 et le maintenir repoussé tandis que le rotor 403 tournera fou.If a rotation of the rotor 403 is caused, from the position of FIG. 8, the pusher 454 is slightly repelled radially by the lug 62, when the rotor begins to rotate about its axis. The cylindrical outer surface of the rotor 403, at the edge of the recess 79, will engage under the pusher 454 and keep it pushed back while the rotor 403 will turn mad.

Comme illustré sur la figure 10, l'entrée du logement du rotor peut être fermée par un volet 82 soumis à un rappel élastique, ce volet 82 s'effaçant, de manière classique, lors de l'introduction d'une clé.As illustrated in FIG. 10, the entrance to the rotor housing can be closed by a flap 82 subjected to an elastic return, this flap 82 disappearing, in a conventional manner, during the introduction of a key.

La batteuse 404 enveloppe le bout du stator 402 (voir figure 10) et l'organe d'indexation 454 de la batteuse, relativement au stator, est réalisé en une seule pièce.The thresher 404 envelops the end of the stator 402 (see FIG. 10) and the indexing member 454 of the thresher, relative to the stator, is made in one piece.

Ceci étant, le fonctionnement du verrou des figures 8 à 12 résulte immédiatement des explications précédentes.That said, the operation of the lock of FIGS. 8 to 12 immediately results from the preceding explanations.

Lorsqu'une clé conforme 407 est introduite, comme illustré sur la figure 12, toutes les échancrures 70 s'alignent et permettent l'entrée du bec 60 du pêne et le basculement de ce pêne 406 dans le sens contraire des aiguilles d'une montre selon la représentation des figures 8, 9, 11 et 12, autour de l'axe géométrique d'articulation 64.When a conforming key 407 is inserted, as illustrated in FIG. 12, all the notches 70 align and allow the entry of the beak 60 of the bolt and the tilting of this bolt 406 in the counterclockwise direction according to the representation of FIGS. 8, 9, 11 and 12, around the geometric axis of articulation 64.

Dans ces conditions, l'ergot 62 entre dans l'encoche 468 comme illustré sur la figure 11 ce qui permet la descente du poussoir 454 et l'alignement de la rainure 472 avec la paroi du stator 402. L'entrée de l'extrémité inférieure 80 du poussoir dans l'évidement 79 contribue à établir une liaison en rotation entre le rotor 403 et la batteuse 404. La coopération de l'encoche 468 de l'ergot 62 et de l'extrémité concave de la partie 80 contribue également à cette liaison.Under these conditions, the lug 62 enters the notch 468 as illustrated in FIG. 11 which allows the descent of the pusher 454 and the alignment of the groove 472 with the wall of the stator 402. The entry of the end lower 80 of the pusher in the recess 79 contributes to establishing a rotational connection between the rotor 403 and the thresher 404. The cooperation of the notch 468 of the lug 62 and the concave end of the part 80 also contributes to this bond.

La rotation de la clé conforme 407 entraîne en rotation le rotor 403 et la batteuse 404, ce qui commande la serrure.The rotation of the conforming key 407 rotates the rotor 403 and the thresher 404, which controls the lock.

Si une clé non conforme est introduite dans le rotor 403, ou si un outil quelconque est introduit en vue de forcer la serrure, comme expliqué précédemment, le rotor 403 va tourner fou, le poussoir 454 étant écarté radialement vers l'extérieur et s'appuyant contre la surface cylindrique externe du rotor 403.If a non-conforming key is inserted into the rotor 403, or if any tool is inserted in order to force the lock, as explained above, the rotor 403 will turn mad, the pusher 454 being spread radially outwards and s' pressing against the external cylindrical surface of the rotor 403.
