L'invention concerne le domaine des mécanismes d'affichage sonore d'horlogerie, et en particulier des pièces d'horlogerie à sonnerie et/ou boîte à musique, pour l'exécution de sonneries, carillons, mélodies au passage ou à la demande. Plus particulièrement l'invention concerne le domaine des montres musicales, à mouvement mécanique de sonnerie et/ou de jeu de mélodie.The invention relates to the field of sound display mechanisms for timepieces, and in particular to striking timepieces and / or music boxes, for the execution of bells, chimes, melodies in passing or on demand. More particularly, the invention relates to the field of musical watches, with a mechanical striking movement and / or playing a melody.

Arrière-plan de l'inventionBackground of the invention

Les mécanismes de sonnerie d'horlogerie sont de grandes complications, complexes autant par le nombre et la complexité des cinématiques de leurs composants, que selon les modes de fonctionnement dont ils sont capables. Pour les montres comportant des complications supplémentaires telle que répétition minutes, la gestion des sécurités est très complexe, et il est difficile de bloquer des sonneries au passage pour laisser jouer une répétition minutes, ou à l'inverse de bloquer le lancement d'une répétition minutes à l'approche d'une sonnerie au passage, d'empêcher le relancement d'une répétition minutes lorsqu'un cycle de répétition vient d'être lancé, d'empêcher un réglage de minuterie pendant l'exécution d'une sonnerie, ou autre, ces sécurités mettent généralement en œuvre un assez grand nombre d'isolateurs, ce qui complexifie encore le mécanisme et les risques d'interférence.Clockwork striking mechanisms are major complications, complex as much by the number and the complexity of the kinematics of their components, as by the operating modes of which they are capable. For watches with additional complications such as minute repeater, security management is very complex, and it is difficult to block chimes in passing to allow a minute repeater to play, or conversely to block the launch of a repeater. minutes at the approach of a bell in passing, to prevent the restart of a minute repeater when a repetition cycle has just been started, to prevent a timer setting during the execution of a bell, or other, these safeties generally use a fairly large number of insulators, which further complicates the mechanism and the risks of interference.

Le problème est encore plus délicat pour une pièce d'horlogerie capable de fonctionner selon différents modes de sonnerie, avec des mélodies différenciées, notamment un carillon, ou encore avec différents jeux de timbres, quand cette pièce d'horlogerie comporte des moyens de sélection de mode de sonnerie, de mélodie, de timbres. Et il s'agit d'assurer une sécurisation totale, non seulement des composants du mécanisme de sonnerie ou du mécanisme musical, mais aussi de ce mécanisme de sélection, également complexe. Il faut tout particulièrement prévenir les accumulations de contraintes dans le mécanisme, en particulier au niveau des levées, et notamment empêcher toute collision entre les pièces de quarts et les levées.The problem is even more delicate for a timepiece capable of operating according to different ringing modes, with differentiated melodies, in particular a chime, or even with different sets of gongs, when this timepiece comprises means for selecting mode of ringing, melody, stamps. And it is a matter of ensuring total security, not only of the components of the striking mechanism or of the musical mechanism, but also of this selection mechanism, which is also complex. It is especially necessary to prevent the accumulation of stresses in the mechanism, in particular at the level of the lifts, and in particular to prevent any collision between the quarter pieces and the lifts.

Les brevets EP2947523B1 , EP3096189B1 , EP3136188B1 , et les demandes CH01718/16 , CH00964/17 , CH00965/17 , CH00966/17 , du même déposant, abordent déjà différents aspects de cette problématique difficile, puisqu'il s'agit, d'une part d'empêcher l'utilisateur de lancer une action de sélection ou de déclenchement d'une sonnerie ou d'une mélodie à un instant inopportun, et d'autre part d'empêcher le mécanisme de la pièce d'horlogerie de démarrer un cycle de sonnerie ou de mélodie lorsque l'utilisateur est en train d'effectuer une action sur certains des moyens de commande manuelle de cette pièce d'horlogerie. En particulier, la demande CH01422/17 du même déposant présente un mécanisme de sécurité de mise à l'heure, pour un mécanisme de sonnerie à régulateur EP2498143A1 porte sur un mécanisme d'isolement entre mécanismes horlogers de déclenchement de signaux sonores.Licences EP2947523B1 , EP3096189B1 , EP3136188B1 , and requests CH01718 / 16 , CH00964 / 17 , CH00965 / 17 , CH00966 / 17 , from the same applicant, already tackle various aspects of this difficult problematic, since it is, on the one hand, to prevent the user from launching an action of selection or triggering of a ringtone or a melody to an inopportune moment, and on the other hand to prevent the mechanism of the timepiece from starting a ringing or melody cycle when the user is in the process of performing an action on some of the manual control means of this timepiece. In particular, the demand CH01422 / 17 from the same applicant presents a safety mechanism for setting the time, for a striking mechanism with regulator EP2498143A1 concerns an isolation mechanism between watch mechanisms for triggering sound signals.

Résumé de l'inventionSummary of the invention

L'invention se propose plus particulièrement d'empêcher tout déclenchement de sonnerie ou d'exécution de mélodie, lorsque l'utilisateur est en train de manœuvrer les moyens de sélection manuelle. A cet effet, l'invention concerne une pièce d'horlogerie selon la revendication 1.The invention more particularly proposes to prevent any triggering of ringing or melody execution, when the user is operating the manual selection means. To this end, the invention relates to a timepiece according to claim 1.

The work of François LECOULTRE “Complicated watches”, Horlogères Publishing, Bienne (Switzerland), 1985, ISBN 2-88175-000-1, describes in detail the basic mechanisms constituting striking mechanisms, on pages 97 to 205 , under different chapters:
  • ringtones,
  • ancient repetition,
  • modern quarter repeat,
  • simplified repetition,
  • half-quarter repetition,
  • Breguet half-quarter repeat,
  • five-minute repetition,
  • minute repeater,
  • big bell.

Sauf nécessité, ces mécanismes de base ne seront pas repris ici en détail, le spécialiste des sonneries saura en retrouver la constitution dans cet ouvrage de référence universel, en particulier dans les deux derniers chapitres cités ci-dessus.Unless necessary, these basic mechanisms will not be repeated here in detail; the specialist in ring tones will be able to find their constitution in this universal reference work, in particular in the last two chapters cited above.

Le mécanisme de sonnerie 100 comporte, de façon classique, au moins un mobile de référence, et de préférence une pluralité de mobiles de référence, comportant des limaçons et/ou étoiles de référence temporelle, et notamment un limaçon des minutes, un limaçon des quarts, un limaçon des heures.The striking mechanism 100 conventionally comprises at least one reference mobile, and preferably a plurality of reference mobile, including time reference snails and / or stars, and in particular a minute snail, a quarter snail. , a snail for hours.

Ce mécanisme de sonnerie 100 comporte encore au moins un mobile entraîneur de sonnerie 1, tel qu'exposé notamment au chapitre « grande sonnerie » de l'ouvrage « Les montres compliquées » et visible notamment en figure 40 de cet ouvrage. Ce mobile entraîneur de sonnerie 1 comporte classiquement un rochet de détente 2 et un pignon de crémaillère.This striking mechanism 100 also comprises at least one striking mobile device 1, as explained in particular in the chapter "Grande Singer" of the book "Complicated watches" and visible in particular in figure 40 of this book. This ringing drive mobile 1 conventionally comprises a detent ratchet 2 and a rack pinion.

Le mécanisme de sonnerie 100 coopère avec le mouvement 500, qui entraîne le ou les mobiles de référence, et dont une sortie particulière est illustrée à la figure 28, sous la forme non limitative d'une étoile de déclenchement de sonnerie par le mouvement, ajustée sur une chaussée, et comportant quatre dents, de façon à pouvoir soulever, à chaque quart d'heure, une bascule intermédiaire de déclenchement par le mouvement, dénommée ci-après levée.The striking mechanism 100 cooperates with the movement 500, which drives the reference mobile (s), and of which a particular output is illustrated on figure 28 , in the nonlimiting form of a star for triggering the ringing by movement, adjusted on a roadway, and comprising four teeth, so as to be able to lift, every quarter of an hour, an intermediate rocker triggering by movement, hereinafter referred to as lifting.

Le mobile entraîneur de sonnerie 1 est ainsi porteur d'un rochet de détente 2, lequel est agencé pour coopérer avec au moins un cliquet d'actionnement au passage 3 commandé par le mouvement 500, notamment par la coopération entre l'étoile de la figure 28 et la bascule d'enclenchement 73 de la figure 32, et tel qu'exposé dans la demande CH00964/17 du même déposant, ou un cliquet de répétition 4 par une bascule de déclenchement à la demande 5, visible sur la figure 29, manœuvrable par un utilisateur, par exemple pour une commande de répétition minutes ou similaire, et tel qu'exposé dans la même demande CH00964/17 du même déposant.The ringing drive mobile 1 is thus carrying a detent ratchet 2, which is arranged to cooperate with at least one actuating pawl at the passage 3 controlled by the movement 500, in particular by the cooperation between the star of the figure 28 and the latching lever 73 of the figure 32 , and as set out in the application CH00964 / 17 from the same depositor, or a repeating pawl 4 by a trigger-on-demand latch 5, visible on the figure 29 , operable by a user, for example for a minute repeater control or the like, and as set out in the same application CH00964 / 17 from the same depositor.

Le mécanisme de sonnerie 100 comporte un levier de débrayage de sonnerie 6 apte à empêcher l'accès d'un tel cliquet 3, 4, au rochet de détente 2, sous l'action d'une bascule d'inversion de sonnerie 7, telle que décrite dans les demandes CH00964/17 , CH00965/17 , CH00966/17 , du même déposant. Cette bascule d'inversion de sonnerie 7 est manœuvrable, ou bien par une tige de mise à l'heure 8 que comporte le mouvement 500, ou bien par une commande principale 10 de sélection de sonnerie ou de mélodie que comporte le mécanisme de sonnerie 100, ou bien encore par un mécanisme d'arrêtage en cas de ressource d'énergie insuffisante que comporte le mécanisme de sonnerie 100. Un tel mécanisme d'arrêtage, agencé pour prévenir le lancement de toute sonnerie lorsque la réserve de sonnerie, notamment au niveau d'un barillet de sonnerie ou similaire, est vide ou insuffisante, n'est pas illustré ni détaillé ici, et fait l'objet de la demande CH00964/17 du même déposant.The striking mechanism 100 comprises a striking disengagement lever 6 capable of preventing access of such a pawl 3, 4, to the detent ratchet 2, under the action of a ringing reversal lever 7, such as as described in the requests CH00964 / 17 , CH00965 / 17 , CH00966 / 17 , from the same depositor. This ringing reversal flip-flop 7 can be operated either by a time-setting rod 8 which the movement 500 comprises, or else by a main control 10 for selecting ringing or melody which the striking mechanism 100 comprises. , or even by a stopping mechanism in the event of insufficient energy resource included in the ringing mechanism 100. Such a stopping mechanism, designed to prevent the launch of any ringing when the ringing reserve, in particular at the level of a striking cylinder or similar, is empty or insufficient, is not illustrated or detailed here, and is the subject of the request CH00964 / 17 from the same depositor.

Selon l'invention, le mécanisme de sonnerie comporte un dispositif de sécurité de déclenchement durant une sélection de sonnerie ou de mélodie, qui est agencé pour empêcher le déclenchement de toute sonnerie, que ce soit par le mouvement 500 ou par un utilisateur. Ce dispositif de sécurité de déclenchement comporte une bascule de sécurité de déclenchement 20, dont le pivotement, sous l'action d'une sélection de sonnerie ou de mélodie effectuée sur la commande principale 10 par un utilisateur, éloigne tout cliquet 3, 4, du rochet de détente 2. Et le mécanisme de sonnerie 100 comporte des moyens de rappel élastique, qui sont agencés pour ramener la commande principale 10 dans une position unique de repos en l'absence d'action d'un utilisateur.According to the invention, the ringing mechanism comprises a triggering safety device during a ringing or melody selection, which is arranged to prevent the triggering of any ringing, whether by the movement 500 or by a user. This tripping safety device comprises a tripping safety latch 20, the pivoting of which, under the action of a ring or melody selection made on the main control 10 by a user, moves any pawl 3, 4 away from the trigger ratchet 2. And the striking mechanism 100 comprises elastic return means, which are arranged to return the main control 10 to a single rest position in the absence of action by a user.

Plus particulièrement, la commande principale 10 comporte une bascule principale de commande 11 pivotante, qui porte une goupille de commande 12. Cette goupille de commande 12 est agencée pour coopérer en appui, sous l'action d'un ressort principal de commande 9, avec une première surface 23 de la bascule de sécurité de déclenchement 20 dans une première course angulaire autorisant des manœuvres de déclenchement, et avec une deuxième surface 24 de la bascule de sécurité de déclenchement 20 dans une deuxième course angulaire de dégagement de la bascule de sécurité de déclenchement 20 interdisant toute manœuvre de déclenchement de sonnerie. La bascule de sécurité de déclenchement 20 est poussée vers la goupille de commande 12 par le rappel d'un ressort de bascule de sécurité de déclenchement 29. Le mouvement 500 comporte une goupille fixe 28, qui sert de position d'appui à la bascule de sécurité de déclenchement 20 lorsque cette dernière est en position de repos.More particularly, the main control 10 comprises a pivoting main control lever 11, which carries a control pin 12. This control pin 12 is arranged to cooperate in support, under the action of a main control spring 9, with a first surface 23 of the trigger safety latch 20 in a first angular travel allowing tripping maneuvers, and with a second surface 24 of the tripping safety latch 20 in a second angular travel of release of the tripping safety latch 20 preventing any ringing tripping maneuver. The release safety latch 20 is pushed towards the control pin 12 by the return of a release safety latch spring 29. The movement 500 has a fixed pin 28, which serves as a support position for the latch. release safety 20 when the latter is in the rest position.

Dans la position de repos de la commande principale 10, la goupille de commande 12 fait face à la première surface 23, dont elle est séparée d'une première distance de sécurité S1 non nulle, tel que visible sur la figure 3.In the rest position of the main control 10, the control pin 12 faces the first surface 23, from which it is separated by a first non-zero safety distance S1, as can be seen on the figure. figure 3 .

Pendant la première course angulaire, la goupille de commande 12 est en appui sur la première surface 23, tel que visible sur la figure 7, où la bascule de sécurité de déclenchement 20 est en appui sur une goupille fixe 28 du mouvement 500, au début d'une action sur le poussoir de la commande principale 10, tandis que, sur la figure 11, la goupille de commande 12 est encore en appui sur la première surface 23, mais la bascule de sécurité de déclenchement 20 n'est plus en appui sur la goupille fixe 28.During the first angular travel, the control pin 12 bears on the first surface 23, as visible on the figure. figure 7 , where the trigger safety latch 20 is supported on a fixed pin 28 of the movement 500, at the start of an action on the push-button of the main control 10, while, on the figure 11 , the control pin 12 is still resting on the first surface 23, but the release safety latch 20 is no longer resting on the fixed pin 28.

Pendant la deuxième course angulaire, la goupille de commande 12 est en appui sur la deuxième surface 24, tant qu'un effort est exercé sur la commande principale 10 par un utilisateur, tel que visible sur les figures 15 et 19, où la bascule de sécurité de déclenchement 20 est éloignée de la goupille fixe 28.During the second angular stroke, the control pin 12 bears on the second surface 24, as long as a force is exerted on the main control 10 by a user, as seen on the figures 15 and 19 , where the trigger safety latch 20 is moved away from the fixed pin 28.

Plus particulièrement, la deuxième surface 24 de la bascule de sécurité de déclenchement 20 est adjacente à la première surface 23, dont elle est séparée par une arête ou par un plat intermédiaire, dont le franchissement lors d'une action sur la commande principale 10 correspond à la fin de la première course angulaire, et à l'enclenchement de la sécurité empêchant le déclenchement de toute sonnerie.More particularly, the second surface 24 of the trigger safety latch 20 is adjacent to the first surface 23, from which it is separated by an edge or by an intermediate flat, the crossing of which during an action on the main control 10 corresponds at the end of the first angular travel, and when the safety device engages preventing the triggering of any bell.

Dans la variante non limitative illustrée par les figures, la première surface 23 est sensiblement plate, et est séparée de la deuxième surface 24, sensiblement cylindrique, par une arête. La deuxième surface 24 est coaxiale avec l'axe de pivotement de la bascule principale de commande 11 lorsque la sécurité est activée.In the non-limiting variant illustrated by the figures, the first surface 23 is substantially flat, and is separated from the second surface 24, which is substantially cylindrical, by an edge. The second surface 24 is coaxial with the pivot axis of the main control lever 11 when the safety is activated.

Dans une autre variante non illustrée, la première surface 23 et la deuxième surface 24 sont deux surfaces sensiblement cylindriques, et sensiblement axées sur l'axe de pivotement de la bascule principale de commande 11, dont l'une est plus éloignée que l'autre, et sont séparées par un plat intermédiaire. Et, de la même façon, la deuxième surface 24 est coaxiale avec l'axe de pivotement de la bascule principale de commande 11 lorsque la sécurité est activée.In another variant not shown, the first surface 23 and the second surface 24 are two substantially cylindrical surfaces, and substantially centered on the pivot axis of the main control lever 11, one of which is more distant than the other, and are separated by an intermediate plate. And, in the same way, the second surface 24 is coaxial with the pivot axis of the main control lever 11 when the safety is activated.

D'autres agencements sont naturellement possibles, et dépendent notamment de l'espace disponible au voisinage de la commande principale 10, laquelle comporte, dans la variante illustrée par les figures, une bascule principale de commande 11 sur laquelle agit un poussoir non représenté manœuvrable par l'utilisateur.Other arrangements are naturally possible, and depend in particular on the space available in the vicinity of the main control 10, which comprises, in the variant illustrated by the figures, a main control rocker 11 on which acts a pushbutton (not shown) which can be operated by the user.

De façon avantageuse, la bascule d'inversion de sonnerie 7 comporte un excentrique 71, qui est agencé pour venir en appui sur une surface d'appui 22 que comporte la bascule de sécurité de déclenchement 20, pour le réglage fin de la course de pivotement de la bascule d'inversion de sonnerie 7, et pour assurer le dégagement de chaque cliquet 3, 4, par rapport au rochet de détente 2.Advantageously, the ringing reversal lever 7 comprises an eccentric 71, which is arranged to come to bear on a bearing surface 22 which the release safety lever 20 comprises, for the fine adjustment of the pivoting stroke. of the ringing reversal lever 7, and to ensure the release of each pawl 3, 4, relative to the trigger 2.

Lorsque la goupille de commande 12 entre en contact avec la première surface 23 de la bascule de sécurité de déclenchement 20, cette dernière entre en contact avec l'excentrique 71 par sa surface d'appui 22.When the control pin 12 comes into contact with the first surface 23 of the trigger safety latch 20, the latter comes into contact with the eccentric 71 via its bearing surface 22.

Cette sécurité s'active pendant la course à vide de la bascule principale de commande 11 : pendant que la goupille de commande 12 se déplace sur la première surface 23, la distance de sécurité passe progressivement de la valeur de la deuxième distance de sécurité S2 à la valeur nulle, et la bascule d'inversion de sonnerie 7 entame sa course pour entraîner le levier de débrayage de sonnerie 6 qui déconnecte les deux cliquets 3, 4, en les maintenant à distance du rochet de détente 2.This safety is activated during the empty stroke of the main control lever 11: while the control pin 12 moves on the first surface 23, the safety distance gradually changes from the value of the second safety distance S2 to the value zero, and the ringing reversal flip-flop 7 begins to travel to drive the ringing release lever 6 which disconnects the two pawls 3, 4, keeping them away from the trigger 2.

Lorsque l'utilisateur fait une sélection de mélodie par une action sur la bascule principale de commande 11, la goupille de commande 12 passe de la première surface 23 à la deuxième surface 24 de la bascule de sécurité de déclenchement 20. De ce fait, la bascule principale de commande 11 entre en contact, avec sa surface d'appui 22, sur cet excentrique 71 de la bascule d'inversion de sonnerie 7, laquelle vient ensuite déconnecter les cliquets 3, 4, par la connexion avec le levier de débrayage de sonnerie 6.When the user makes a melody selection by an action on the main control latch 11, the control pin 12 moves from the first surface 23 to the second surface 24 of the trigger safety latch 20. As a result, the The main control lever 11 comes into contact, with its bearing surface 22, on this eccentric 71 of the ringing reversal lever 7, which then disconnects the pawls 3, 4, through the connection with the release lever of ringtone 6.

Dans une autre variante non illustrée, la bascule d'inversion de sonnerie 7 porte une simple goupille agencée pour coopérer avec la surface d'appui 22. Dans une autre variante encore, non illustrée, la bascule d'inversion de sonnerie 7 porte une ouverture agencée pour coopérer avec une goupille de la bascule de sécurité de déclenchement 20, ou avec une goupille fixée à la platine du mouvement 500.In another variant, not illustrated, the ringing reversal latch 7 carries a single pin arranged to cooperate with the bearing surface 22. In yet another variant, not illustrated, the ringing reversal latch 7 carries an opening arranged to cooperate with a pin of the safety release latch 20, or with a pin fixed to the movement plate 500.

Plus particulièrement, dans la position de repos de la commande principale 10, l'excentrique 71 fait face à la surface d'appui 22 dont elle est séparée d'une deuxième distance de sécurité S2 non nulle, tel que visible sur la figure 4.More particularly, in the rest position of the main control 10, the eccentric 71 faces the bearing surface 22 from which it is separated by a second non-zero safety distance S2, as visible on the figure. figure 4 .

Pendant une première partie de la première course angulaire, cet excentrique 71 fait face à la surface d'appui 22 dont elle est encore séparée d'une deuxième distance de sécurité S2 non nulle, tel que visible sur la figure 8, au même instant que la figure 7, au début d'une action sur le poussoir de la commande principale 10, alors que la goupille de commande 12 est en appui sur la première surface 23, et que la bascule de sécurité de déclenchement 20 est en appui sur la goupille fixe 28.During a first part of the first angular travel, this eccentric 71 faces the bearing surface 22 from which it is still separated by a second non-zero safety distance S2, as visible on the figure. figure 8 , at the same time as the figure 7 , at the start of an action on the main control pusher 10, while the control pin 12 is resting on the first surface 23, and the release safety latch 20 is resting on the fixed pin 28.

Pendant une deuxième partie, consécutive à la première partie, de la première course angulaire, tel que visible sur la figure 12, au même instant que la figure 11, l'excentrique 71 est en appui sur la surface d'appui 22.During a second part, following the first part, of the first angular travel, as visible on the figure 12 , at the same time as the figure 11 , the eccentric 71 rests on the bearing surface 22.

Pendant la deuxième course angulaire, l'excentrique 71 est en appui sur la surface d'appui 22, tant qu'un effort est exercé sur la commande principale 10 par un utilisateur, tel que visible sur la figure 16, au même instant que la figure 15, qui correspondent à la fin de la course à vide et à la fin de la phase d'enclenchement de la sécurité, ainsi que sur la figure 20, au même instant que la figure 19, et qui correspond à la fin de la course du poussoir, la sélection étant alors effectuée, par exemple sous la forme d'un changement de mélodie ou de mode de sonnerie, ou encore de choix de timbre, ou autre. Cette disposition permet d'empêcher toute casse de mécanisme.During the second angular travel, the eccentric 71 bears on the bearing surface 22, as long as a force is exerted on the main control 10 by a user, as visible on the figure 16 , at the same time as the figure 15 , which correspond to the end of the empty stroke and the end of the safety engagement phase, as well as to the figure 20 , at the same time as the figure 19 , and which corresponds to the end of the stroke of the pusher, the selection then being made, for example in the form of a change of melody or of ringing mode, or even of choice of timbre, or the like. This arrangement makes it possible to prevent any breakage of the mechanism.

Dans la version non limitative illustrée par les figures, la commande principale 10 de sélection de sonnerie ou de mélodie comporte une roue à colonnes 30. Et la bascule principale de commande 11 est alors une bascule principale de commande de roue à colonnes, qui comporte un crochet 13, qui est agencé pour entraîner par traction des dents 31 de la roue à colonnes 30, laquelle est maintenue en position par un sautoir de roue à colonnes 32. Et le ressort principal de commande 9 est alors un ressort principal de commande de roue à colonnes, qui comporte au moins un pion 93, 94, pour son positionnement. Les brevets EP3096189B1 et EP3136188B1 du même déposant exposent le fonctionnement d'une telle roue à colonnes, en liaison avec une telle bascule de commande.In the non-limiting version illustrated by the figures, the main control 10 for selecting ring or melody comprises a column wheel 30. And the main control latch 11 is then a main column wheel control latch, which comprises a column wheel. hook 13, which is arranged to drive teeth 31 of column wheel 30 by traction, which is held in position by a column wheel jumper 32. And the main control spring 9 is then a main wheel control spring with columns, which comprises at least one pin 93, 94, for its positioning. Licences EP3096189B1 and EP3136188B1 by the same applicant describe the operation of such a column wheel, in connection with such a control rocker.

La première course angulaire, lors de laquelle la goupille de commande 12 est en appui sur la première surface 23 de la bascule de sécurité de déclenchement 20, correspond à la course à vide de la bascule principale de commande de roue à colonnes 11, c'est-à-dire que cette bascule principale de commande de roue à colonnes 11 n'est pas encore entrée en contact avec la roue à colonnes 30.The first angular stroke, during which the control pin 12 bears on the first surface 23 of the trigger safety latch 20, corresponds to the empty travel of the main column wheel control latch 11, c ' that is to say that this main column wheel control latch 11 has not yet come into contact with the column wheel 30.

La première surface 23 permet à elle seule d'enclencher la sécurité de déclenchement selon l'invention. La deuxième surface 24 de la bascule de sécurité de déclenchement 20 permet de conserver cette sécurité de déclenchement active, lors de la suite de la course de la goupille de commande 12 de la bascule principale de commande de roue à colonnes 11.The first surface 23 alone enables the triggering safety device according to the invention to be engaged. The second surface 24 of the tripping safety latch 20 makes it possible to keep this active tripping safety, during the continuation of the travel of the control pin 12 of the main column wheel control latch 11.

D'autres variantes non illustrées peuvent comporter d'autres types de sélecteurs qu'une roue à colonnes, le crochet est alors remplacé par un organe de commande adapté à cet usage.
