Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie mécanique. Elle concerne, plus particulièrement, un mécanisme de sonnerie comportant un barillet muni d'un arbre pour son remontage par un remontoir conventionnel et des râteaux destinés à être entraînés par le barillet pour sonner l'heure courante. Ce mécanisme comprend un système de déclenchement automatique et un système de déclenchement manuel doté d'un organe de commande actionnable par le porteur. Un tel mécanisme comporte sa propre source d'énergie et possédant un système de remontage indépendant de l'enclenchement de la sonnerie.The present invention relates to the field of mechanical watchmaking. It relates, more particularly, a striking mechanism comprising a barrel provided with a shaft for its winding by a conventional winding and rakes to be driven by the barrel to ring the current time. This mechanism comprises an automatic triggering system and a manual triggering system with a control member operable by the wearer. Such a mechanism has its own power source and has a winding system independent of the engagement of the ring.

Etat de la techniqueState of the art

On connaît ce genre de dispositif, notamment dans les montres appelées grandes sonneries. Celles-ci donnent la possibilité de sonner les heures au passage, c'est-à-dire automatiquement tous les quarts et/ou toutes les heures. Il est donc évident que, pour ce faire, le porteur n'a pas besoin d'armer un barillet à chaque sonnerie, comme c'est le cas dans les répétitions à minutes les plus courantes, qui ne sonnent l'heure que sur demande et dans lesquelles un barillet de sonnerie est armé par l'intermédiaire d'une crémaillère lorsque l'utilisateur actionne la targette de commande. On pourra trouver une description complète d'un mécanisme de grande sonnerie conventionnel dans l'ouvrage " Les montres compliquées" de F. Lecoultre, aux Editions Horlogères, pages 182-205 . Le document CH 689 337 donne également un exemple d'un tel mécanisme.We know this kind of device, especially in watches called big ringtones. These give the possibility to ring the hours in passing, that is to say automatically every quarter and / or every hour. It is therefore obvious that, to do this, the wearer does not need to arm a barrel at each ring, as is the case in the most common minute repeaters, which only sound the time on request and in which a ringer barrel is armed via a rack when the user actuates the control bolt. A full description of a conventional grand-ring mechanism can be found in the book " Complicated watches "by F. Lecoultre, at Horloger's Editions, pages 182-205 . The document CH 689 337 also gives an example of such a mechanism.

Le barillet peut être armé par le porteur, par le biais d'un système de remontage manuel conventionnel comportant principalement une tige de remontoir coopérant avec l'arbre de barillet. Dans certaines pièces, le barillet de sonnerie peut également être armé automatiquement, par le biais d'un système de remontage automatique conventionnel comportant principalement une masse oscillante coopérant avec l'arbre de barillet. On connaît également du document US 4,33,225 , un mécanisme dans lequel le barillet de sonnerie est armé par le levier de déclenchement de la sonnerie. Le levier comporte un cliquet coopérant avec le rochet du barillet afin de régler la tension du ressort de sonnerie.The barrel can be armed by the carrier, by means of a conventional manual winding system mainly comprising a winding stem cooperating with the barrel shaft. In some rooms, the striking barrel can also be automatically armed, by means of a conventional automatic winding system mainly comprising an oscillating mass cooperating with the barrel shaft. Document is also known US 4.33,225 , a mechanism in which the ringer barrel is armed by the trigger lever of the ringer. The lever comprises a pawl cooperating with the ratchet of the barrel to adjust the tension of the ringing spring.

Ce barillet fournit l'énergie nécessaire aux sonneries, qu'elles soient déclenchées sur demande ou au passage, le barillet étant respectivement libéré soit manuellement, soit automatiquement.This barrel provides the energy required for the ringtones, whether triggered on demand or in transit, the barrel being released respectively manually or automatically.

Lorsque le porteur d'une grande sonnerie déclenche manuellement une sonnerie, il prélève de l'énergie qui manquera, à un moment ou à un autre, pour les prochaines sonneries au passage. Il n'est pas très heureux d'obliger l'utilisateur à réarmer le barillet de sonnerie par la tige de remontoir à chaque fois qu'il fait sonner sa montre, de manière à ce qu'il soit sûr que les prochaines sonneries au passage pourront s'effectuer.When the bearer of a large ring raises manually a ring, it takes energy that will, at one time or another, be missing for the next ringing tones. He is not very happy to oblige the user to reset the barrel of the ring by the winding stem every time he makes his watch ring, so that he is sure that the next ringtones in passing can be done.

Pour permettre au moins à l'utilisateur de pouvoir contrôler la réserve de marche du barillet de sonnerie, certaines pièces comportent un indicateur spécialement dédié à afficher cette information. Bien qu'apportant un certain confort au porteur, cet affichage ne résout pas le problème de consommation supplémentaire de l'énergie du barillet de sonnerie qu'engendre une sonnerie déclenchée manuellement.To allow at least the user to be able to control the power reserve of the barrel of ringing, some parts include an indicator especially dedicated to display this information. Although providing a certain comfort to the wearer, this display does not solve the problem of additional energy consumption of the barrel of ringing engendered a manually triggered ring.

La présente invention a pour but de résoudre ce problème en proposant un mécanisme de grande sonnerie dans lequel les déclenchements manuels ne sont pas préjudiciables à la réserve de marche du barillet de sonnerie.The present invention aims to solve this problem by proposing a large bell mechanism in which the manual triggers are not detrimental to the power reserve of the barrel ring.

Divulgation de l'inventionDisclosure of the invention

De façon plus précise, l'organe de commande d'un mécanisme de sonnerie selon l'invention est relié cinématiquement à l'arbre de barillet par l'intermédiaire d'un système d'embrayage agencé de manière à ce que :

  • l'organe de commande et l'arbre soient liés cinématiquement lors du déplacement dudit organe dans un premier sens pour charger le barillet, et
  • que l'organe de commande et l'arbre soient indépendants cinématiquement l'un de l'autre lors du déplacement de l'organe dans un deuxième sens, ou lors du pivotement de l'arbre dans le deuxième sens.
More specifically, the control member of a striking mechanism according to the invention is kinematically connected to the barrel shaft by means of a clutch system arranged so that:
  • the control member and the shaft are kinematically connected during the displacement of said member in a first direction to load the barrel, and
  • that the control member and the shaft are kinematically independent of each other during movement of the member in a second direction, or during pivoting of the shaft in the second direction.

L'invention est définie par les revendications annexées.The invention is defined by the appended claims.

Avantageusement, un rouage relié cinématiquement à l'arbre de barillet, est entraîné par l'organe de commande.Advantageously, a train connected kinematically to the barrel shaft is driven by the control member.

Selon un mode de réalisation préféré, le système d'embrayage est un système d'encliquetage intercalé entre le rouage et l'arbre de barillet.According to a preferred embodiment, the clutch system is a locking system interposed between the gear train and the barrel shaft.

En outre, l'organe de commande comporte un système de rappel indépendant du barillet.In addition, the control member comprises an independent return system of the barrel.

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

Le mécanisme représenté au dessin est décrit en détail dans les demandes EP 1909149 et EP 1925995 . L'homme du métier pourra s'y référer pour une meilleure compréhension de l'ensemble du mécanisme dans lequel le dispositif selon l'invention prend place. L'invention n'est pas limitée au mécanisme de sonnerie proposé mais peut s'adapter à tout type de grande sonnerie.The mechanism shown in the drawing is described in detail in the applications EP 1909149 and EP 1925995 . The skilled person can refer to it for a better understanding of the entire mechanism in which the device according to the invention takes place. The invention is not limited to the proposed striking mechanism but can adapt to any type of big ring.

Un mécanisme de grande sonnerie comporte généralement

  • une série de limaçons 10 entraînés par un mouvement de base d'une pièce d'horlogerie dans laquelle le mécanisme est monté, et fournissant des informations sur le temps courant,
  • des râteaux 12 agencés pour coopérer avec ces limaçons 10 pour actionner des marteaux frappant sur des timbres afin de produire une sonnerie identifiant le temps courant, et
  • un barillet 14 pour fournir, par l'intermédiaire d'un rouage 16 terminé par un organe régulateur 18, de l'énergie destinée à entraîner les râteaux 12 pour produire la sonnerie.
A grand bell mechanism usually features
  • a series of snails 10 driven by a basic movement of a timepiece in which the mechanism is mounted, and providing information on the current time,
  • rakes 12 arranged to cooperate with these snails 10 to operate hammers striking stamps to produce a ring identifying the current time, and
  • a barrel 14 for providing, via a gear train 16 terminated by a regulating member 18, energy for driving the rakes 12 to produce the buzzer.

Le barillet 14 est généralement de type conventionnel et comporte:

  • un tambour de barillet 14a, qui est une sorte de boîte cylindrique munie d'une denture extérieure pour entraîner le rouage,
  • un arbre de barillet 14b pivotant entre pont et platine et muni d'un crochet disposé sur sa bonde,
  • un ressort lame, non visible et fixé, par une première extrémité à un dégagement opéré sur le diamètre intérieur du tambour 14a et, par une deuxième extrémité au crochet de l'arbre de barillet, et
  • un couvercle 14c fermant le tambour.
The barrel 14 is generally of conventional type and comprises:
  • a barrel drum 14a, which is a kind of cylindrical box provided with external toothing to drive the gear,
  • a barrel shaft 14b pivoting between bridge and plate and provided with a hook disposed on its bung,
  • a leaf spring, not visible and fixed, by a first end to a clearance operated on the inside diameter of the drum 14a and, by a second end to the hook of the barrel shaft, and
  • a lid 14c closing the drum.

Pour armer le ressort de barillet afin que celui-ci emmagasine de l'énergie, il faut faire pivoter l'arbre de barillet 14b de manière à enrouler autour de lui le ressort.To arm the barrel spring so that it stores energy, it is necessary to rotate the barrel shaft 14b so as to wrap the spring around it.

Le barillet 14 peut être remonté par un système de remontage conventionnel représenté sur la figure 2 et actionné par une tige de remontoir 20 destinée à être logée dans la carrure de la boîte dans laquelle prend place le mouvement. La boîte de montre n'a pas été représentée au dessin. Au moyen d'un ensemble bien connu de l'homme du métier comprenant une tirette 22 et un pignon coulant 24, la tige de remontoir 20 peut occuper une première position poussée, permettant généralement la mise à l'heure et dans laquelle elle n'interagit pas avec le barillet et une deuxième position tirée dans laquelle elle est reliée cinématiquement avec l'arbre de barillet 14b. Cette liaison cinématique entre la tige de remontoir 20 et l'arbre de barillet 14b se fait par l'intermédiaire d'un train de rouage 26 se terminant par un rochet monté à carré sur l'arbre de barillet, à une première de ses extrémités. Un cliquet 28 empêche le ressort de se dévider par l'arbre 14b, forçant ainsi l'énergie emmagasinée à sortir par le tambour 14a du barillet. Bien entendu, un système de remontage automatique peut tout à fait être utilisé pour remonter le barillet.The barrel 14 can be reassembled by a conventional winding system represented on the figure 2 and actuated by a winding stem 20 intended to be housed in the middle of the box in which the movement takes place. The watch case was not shown in the drawing. By means of an assembly well known to those skilled in the art comprising a pull tab 22 and a sliding pinion 24, the winding stem 20 can occupy a first pushed position, generally allowing time setting and in which it does not interact with the barrel and a second drawn position in which it is kinematically connected with the barrel shaft 14b. This kinematic connection between the winding stem 20 and the barrel shaft 14b is via a gear train 26 ending in a square ratchet on the barrel shaft, at a first end thereof. . A pawl 28 prevents the spring to unwind by the shaft 14b, thereby forcing the stored energy out through the drum 14a of the barrel. Of course, an automatic winding system can be used to wind the barrel.

Lorsque le mécanisme de sonnerie est au repos, le tambour 14a du barillet est verrouillé, par exemple au niveau du régulateur 18, et le ressort ne libère pas d'énergie. Lors du déclenchement d'une sonnerie, qu'il soit manuel ou au passage, l'une des étapes principales du déroulement de la sonnerie est le déverrouillage du tambour 14a du barillet. On pourra se référer aux demandes de brevet ou aux ouvrages précités pour la description de la manière dont le barillet est déverrouillé au cours de la sonnerie. Cet aspect n'étant pas l'essentiel de l'invention, il ne sera pas décrit en détail dans la présente.When the striking mechanism is at rest, the drum 14a of the barrel is locked, for example at the regulator 18, and the spring does not release energy. When triggering a ring, whether manual or in passing, one of the main steps of the course of the ring is the unlocking drum 14a of the barrel. Reference may be made to the patent applications or to the aforementioned works for the description of the manner in which the barrel is unlocked during the ringing. This aspect not being the essence of the invention, it will not be described in detail herein.

Naturellement, lorsque l'utilisateur utilise beaucoup le déclenchement manuel de la sonnerie, il peut arriver que le barillet 14 ne conserve pas suffisamment d'énergie pour les sonneries au passage suivantes.Naturally, when the user uses a lot of manual triggering of the ring, it can happen that the barrel 14 does not conserve enough energy for the following ringtones.

Pour pallier cet inconvénient, il est proposé, pour le déclenchement manuel, que l'utilisateur actionne un organe de commande, typiquement une targette 30 se déplaçant solidairement avec une crémaillère 32, à l'instar d'une répétition à minutes conventionnelle. Dans l'exemple représenté, la targette 30 et la crémaillère 32 forment une unique pièce, mais elles pourraient aussi bien être séparées, la targette 30 poussant la crémaillère 32 lorsqu'elle est déplacée.To overcome this drawback, it is proposed, for manual triggering, that the user actuates a control member, typically a bolt 30 moving together with a rack 32, like a conventional minute repeater. In the example shown, the bolt 30 and the rack 32 form a single piece, but they could as well be separated, the bolt 30 pushing the rack 32 when moved.

La crémaillère 32 engrène avec l'arbre de barillet 14b par l'intermédiaire d'un système d'embrayage, de manière à ce que la crémaillère 32 et l'arbre 14b soient liés cinématiquement lors du déplacement de la crémaillère 32 dans un premier sens, mais que ces éléments soient indépendants cinématiquement lors du déplacement de la crémaillère 32 dans le deuxième sens, ou lors du pivotement de l'arbre 14b dans ce deuxième sens.The rack 32 meshes with the barrel shaft 14b by means of a clutch system, so that the rack 32 and the shaft 14b are kinematically connected during the movement of the rack 32 in a first direction , but these elements are kinematically independent when moving the rack 32 in the second direction, or when pivoting the shaft 14b in this second direction.

Ce système d'encliquetage peut être formé d'un anneau 34 coaxial avec le barillet 14, muni d'une denture extérieure 34a et d'une denture intérieure 34b de type dents de loup. Cet anneau 34 est relié à l'arbre de barillet 14b par un ressort radial 36 possédant un moyeu 36a monté à carré sur l'arbre 14b, à sa deuxième extrémité et typiquement deux lames élastiques 36b, exerçant une pression radiale vers l'extérieure de l'anneau et se terminant par une portion dentée coopérant avec la denture intérieure 34b. On notera qu'une seule lame élastique de longueur suffisante peut également convenir. Toutefois, l'utilisation de plusieurs lames permet de partager le couple entre les différentes dents. L'anneau peut être guidé en rotation au moyen d'une plaque, non représentée, chassée dans une creusure que comporte la partie supérieure ou la partie inférieure de l'anneau. La plaque est pivotée sur l'axe du barillet pour assurer la fonction de guidage.This latching system may be formed of a ring 34 coaxial with the barrel 14, provided with an external toothing 34a and an inner toothing 34b of wolf teeth type. This ring 34 is connected to the barrel shaft 14b by a radial spring 36 having a hub 36a mounted squarely on the shaft 14b, at its second end and typically two elastic blades 36b, exerting a radial pressure towards the outside of the ring and ending with a toothed portion cooperating with the internal toothing 34b. Note that a single elastic blade of sufficient length may also be suitable. However, the use of multiple blades can share the torque between the different teeth. The ring can be guided in rotation by means of a plate, not shown, driven into a recess that includes the upper part or the lower part of the ring. The plate is pivoted on the axis of the barrel to provide the guiding function.

Les portions dentées des lames élastiques 36b sont agencées pour coopérer avec les dents de loup de la denture intérieure 34b de manière à ce que le pivotement de l'anneau engendré par le déclenchement de la sonnerie au moyen de la targette 30 entraîne l'arbre de barillet 14b en rotation. En revanche, ni le pivotement de l'arbre de barillet 14b dans l'autre sens, par exemple lors du démontage du mouvement, ni l'entraînement de l'arbre 14b lors du remontage normal, manuel ou automatique, du barillet 14 ne provoque de déplacement de la targette 36.The toothed portions of the resilient blades 36b are arranged to cooperate with the wolf teeth of the internal toothing 34b so that the pivoting of the ring generated by the triggering of the ring by means of the bolt 30 drives the barrel shaft 14b in rotation. On the other hand, neither the pivoting of the barrel shaft 14b in the other direction, for example during the disassembly of the movement, nor the driving of the shaft 14b during the normal manual or automatic winding of the barrel 14 causes moving the bolt 36.

Il va de soi que l'homme du métier pourra utiliser d'autres types d'embrayage ou d'inverseurs, connus de l'état de la technique pour transmettre un mouvement lorsqu'ils sont entraînés dans un sens et pour débrayer une liaison cinématique lorsqu'ils sont entraînés dans l'autre sens. On peut citer, sans qu'il soit besoin de les décrire davantage, des embrayages à galets ou avec ressort débrayeur. Un dispositif de type pignon baladeur peut également être envisagé. Toutefois, le système proposé est particulièrement bien adapté à l'application envisagée, car il est capable de fonctionner avec un couple important, ce qui est le cas ici, tout en ayant un jeu angulaire faible avant le blocage. En outre, le décliquetage est particulièrement léger.It goes without saying that a person skilled in the art will be able to use other types of clutch or inverters known from the state of the art to transmit a movement when they are driven in one direction and to disengage a kinematic linkage. when they are trained in the other direction. We can cite, without it being necessary to describe them further, clutches with rollers or with disengagement spring. A sliding gear type device can also be considered. However, the proposed system is particularly well suited to the intended application, because it is able to operate with a large torque, which is the case here, while having a low angular clearance before blocking. In addition, the declicking is particularly light.

La denture extérieure 34b de l'anneau 34 transmet le mouvement de la targette 30 à une roue 38 avec laquelle elle engrène. Cette roue 38 est munie d'un système de rappel, par exemple un ressort spiral 40, permettant le retour de la targette 30 à sa position de repos puisqu'il ne peut être assuré par l'arbre de barillet, comme c'est le cas dans les répétitions à minutes classiques. Lors du retour de la targette 30 à sa position initiale, l'arbre 14b et la crémaillère 32 sont également indépendants cinématiquement l'un de l'autre.The external toothing 34b of the ring 34 transmits the movement of the bolt 30 to a wheel 38 with which it meshes. This wheel 38 is provided with a return system, for example a spiral spring 40, allowing the return of the bolt 30 to its rest position since it can not be provided by the barrel shaft, as it is the case in classical minute repetitions. When returning the bolt 30 to its initial position, the shaft 14b and the rack 32 are also kinematically independent of one another.

La roue 38 porte également un bras 42 monté sur son axe et se terminant par une zone d'appui destinée à coopérer avec un organe de commande pour déclencher la sonnerie. Cet organe de commande peut être un mobile d'entraînement d'un arbre à came, comme dans la demande EP 1925995 déjà citée. Cet organe de commande peut également être une bascule libérant un cliquet dans un mécanisme conventionnel.The wheel 38 also carries an arm 42 mounted on its axis and ending with a bearing zone intended to cooperate with a control member to trigger the bell. This control member may be a driving wheel of a camshaft, as in the application EP 1925995 already mentioned. This control member can also be a rocker releasing a pawl in a conventional mechanism.

Avantageusement, la position du bras 42 par rapport à la roue peut être réglée simplement, lors de son assemblage de manière à ce que la sonnerie ne soit déclenchée que si la targette a été suffisamment déplacée pour charger le barillet d'une quantité d'énergie au moins sensiblement égale à celle consommée par le déroulement de la sonnerie. Il est donc possible de réarmer le barillet sans déclencher la sonnerie, ce qui offre une alternative pour le remontage du barillet de sonnerie. L'homme du métier pourrait, naturellement, disposer ce bras 42 sur une autre roue que celle proposée, la roue choisie devant simplement être reliée cinématiquement à l'organe de commande lorsqu'il est actionné pour l'enclenchement de la sonnerie.Advantageously, the position of the arm 42 relative to the wheel can be adjusted simply during its assembly so that the ringing is triggered only if the bolt has been moved enough to to charge the barrel with a quantity of energy at least substantially equal to that consumed by the course of the ringing. It is therefore possible to reset the barrel without triggering the ring, which offers an alternative for the winding of the barrel. The person skilled in the art could, of course, arrange this arm 42 on a wheel other than that proposed, the chosen wheel simply having to be kinematically connected to the control member when it is actuated to engage the buzzer.

Ainsi est proposé un mécanisme de sonnerie combinant certains intérêts d'une grande sonnerie, à savoir de pouvoir sonner les heures au passage, et d'une répétition à minutes à armage par crémaillère, à savoir de ne pas être tributaire de l'état de charge d'un barillet de sonnerie pour déclencher la sonnerie. La présence du dispositif d'embrayage permet que l'organe de commande pour le déclenchement manuel de la sonnerie ne soit pas influencé par le déroulement des sonneries au passage ou par le remontage du barillet de sonnerie, problème qui ne se pose évidemment pas dans le cas d'une répétition à minutes conventionnelle.Thus, a ringing mechanism is proposed which combines certain interests of a great bell, namely to be able to ring the hours in passing, and a rack-and-pinion minute repeater, namely not to be dependent on the state of the art. charging a ringer barrel to sound the ring. The presence of the clutch device makes it possible for the control device for manually triggering the ringer not to be influenced by the running of the ringtones when passing or by the winding of the ringer barrel, a problem which obviously does not arise in the case of a conventional minute repetition.

La description ci-dessus a été donnée à titre d'illustration non limitative de l'invention. Ainsi, même si, pour des raisons évidentes d'encombrement, il est plus facile que l'arbre de barillet soit entraîné, à une première extrémité, par le système de remontage normal et, à son autre extrémité, par l'organe de commande du déclenchement manuel de la sonnerie, cela n'est absolument pas obligatoire.The above description has been given by way of non-limiting illustration of the invention. Thus, even if, for obvious reasons of space, it is easier for the barrel shaft to be driven, at a first end, by the normal winding system and, at its other end, by the control member. the manual triggering of the bell, this is not mandatory.

Claims (8)

  1. A striking-work mechanism including a barrel (14) provided with an arbor (14b), and racks (12) intended to be driven by the barrel (14) to strike the current hour, said mechanism comprising an automatic release system and a manual release system provided with a control organ (30),
    characterized in that, to wind the barrel, the arbor (14b) of the barrel can be actuated
    - by a first winding system (20, 22, 24, 26) independent of the engagement of the striking-work, and
    - by the control organ (30), kinematically connected to the barrel arbor (14b) by a coupling system arranged such that the control organ (30) and the arbor (14b) are kinematically connected during the movement of said organ in a first direction to load the barrel, and such that said organ and said arbor are kinematically independent of one another during the movement of said organ in a second direction, or during the pivoting of the arbor in the second direction.
  2. The mechanism according to claim 1, wherein the winding system is kinematically connected to a first end of the arbor (14b), characterized in that a train (34) kinematically connected to a second end of the barrel arbor (14b) is driven by the control organ (30).
  3. The mechanism according to claim 2, characterized in that said coupling system is a click system inserted between said train (34) and the barrel arbor (14b).
  4. The mechanism according to claim 3, characterized in that the train is a ring (34) coaxial with the barrel arbor (14b), provided with an outer toothing (34a), the click system being formed by a toothing (34b) included by the inside of the ring and by a spring (36) having a hub (36a) secured to the arbor (14b) and an elastic blade (36b), exerting radial pressure toward the outside of the ring (34) during the driving.
  5. The mechanism according to claim 4, characterized in that said elastic blades (36b) end with a toothed portion cooperating with the toothing (34b) included by the inside of the ring (34).
  6. The mechanism according to one of the preceding claims, characterized in that the control organ (30) includes a return system independent of the barrel.
  7. The mechanism according to claim 6, characterized in that the return system is a spring (40) cooperating with a wheel (38) meshing with said train (34).
  8. The mechanism according to one of claims 1 to 7, characterized in that a wheel (38) kinematically connected to the control organ (30) bears an arm (42) to release the striking-work, said arm being positioned so as only to release the striking-work when said control organ (30) has traveled enough to load the barrel (14) with a quantity of energy at least substantially equal to that consumed by the unwinding of the striking-work.
