Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un outil d'actionnement d'un correcteur équipant une montre.The present invention relates to a tool for operating a corrector fitted to a watch.

L'invention concerne plus particulièrement un outil permettant d'actionner un bouton-poussoir de petites dimensions encore appelé correcteur qui équipe couramment des montres telles que des montres-bracelets à grandes complications.The invention relates more particularly to a tool making it possible to actuate a small push button, also called a corrector, which is commonly fitted to watches such as large complication wristwatches.

Arrière-plan technologique de l'inventionTechnological background of the invention

Certaines montres, en particulier les montres dites à grandes complications, offrent à leurs utilisateurs un nombre si élevé de fonctions qu'il n'est pas possible de les corriger toutes à l'aide d'une unique couronne de remontage et de correction. C'est pour cette raison que de telles montres comprennent des moyens de commande supplémentaires tels que des boutons-poussoirs. Il existe des boutons-poussoirs de différents types parmi lesquels on trouve des boutons-poussoirs miniatures qui sont typiquement noyés dans la carrure de la montre et que l'on actionne habituellement au moyen d'un instrument pointu. Ces boutons-poussoirs miniatures comprennent classiquement une douille chassée, collée ou vissée dans une ouverture pratiquée dans la carrure de la montre, et une tige de commande cylindrique apte à coulisser librement dans la douille. La douille comprend, du côté extérieur de la boîte de la montre, un premier passage cylindrique adapté aux dimensions d'une première portion de la tige de commande, et du côté intérieur de la boîte de la montre, un second passage cylindrique agencé dans le prolongement du premier passage cylindrique et dont le diamètre intérieur, adapté aux dimensions d'une seconde portion de la tige de commande, est inférieur à celui du premier passage cylindrique. Une garniture d'étanchéité logée dans une saignée ménagée sur un périmètre de la première portion de la tige de commande permet de garantir l'étanchéité entre la tige de commande et la douille. Un tel bouton-poussoir comprend également un ressort hélicoïdal qui se comprime lorsque l'utilisateur appuie sur le bouton-poussoir miniature, et dont la force de rappel ramène la tige de commande en position de repos lorsque l'utilisateur relâche la pression sur le bouton-poussoir.Some watches, in particular so-called grand complication watches, offer their users such a high number of functions that it is not possible to correct them all using a single winding and correction crown. It is for this reason that such watches include additional control means such as push buttons. There are push buttons of different types including miniature push buttons which are typically embedded in the middle of the watch and which are usually activated by means of a pointed instrument. These miniature push buttons conventionally comprise a socket driven, glued or screwed into an opening made in the middle of the watch, and a cylindrical control rod capable of sliding freely in the socket. The socket comprises, on the exterior side of the watch case, a first cylindrical passage adapted to the dimensions of a first portion of the control rod, and on the interior side of the watch case, a second cylindrical passage arranged in the extension of the first cylindrical passage and whose internal diameter, adapted to the dimensions of a second portion of the control rod, is less than that of the first cylindrical passage. A seal housed in a groove formed on a perimeter of the first portion of the control rod makes it possible to guarantee the seal between the control rod and the socket. Such a push button also includes a helical spring which compresses when the user presses the miniature push button, and whose return force returns the control rod to the rest position when the user releases pressure on the button -push.

Des boutons-poussoirs du type décrit ci-dessus ont des dimensions très réduites. De tels boutons-poussoirs permettent donc de gagner de la place. En outre, ils ne font pas saillie de la carrure et ne risquent donc pas d'être actionnés involontairement. Les opérations de correction se font en enfonçant la tige de commande dans la douille à l'encontre de la force de rappel du ressort hélicoïdal au moyen d'un instrument pointu tel qu'un stylo par exemple. Ce dernier point pose problème. En effet, comme mentionné ci-avant, de tels boutons-poussoirs équipent le plus souvent des montres-bracelets à grandes complications. Il s'agit de montres extrêmement onéreuses dont les boîtes sont très souvent réalisées à l'aide de matériaux précieux. Or, les risques de blesser la boîte de la montre et d'altérer son aspect esthétique lorsqu'on manipule un instrument pointu sont importants, ce qui est devenu difficilement acceptable. Bien entendu, il existe toujours la possibilité de retourner la montre en atelier afin qu'elle y soit repolie, mais cela n'est pas très commode.Push buttons of the type described above have very small dimensions. Such push buttons therefore save space. In addition, they do not protrude from the middle and are therefore not likely to be activated unintentionally. Correction operations are carried out by pressing the control rod into the socket against the return force of the helical spring using a pointed instrument such as a pen for example. This last point poses a problem. Indeed, as mentioned above, such push-buttons are most often fitted to wristwatches with large complications. These are extremely expensive watches whose cases are very often made using precious materials. However, the risks of injuring the watch case and altering its aesthetic appearance when handling a sharp instrument are significant, which has become difficult to accept. Of course, there is always the possibility of returning the watch to the workshop so that it can be repolished, but this is not very convenient.

Des boutons-poussoirs du type décrit ci-dessus se retrouvent également sur d'autres objets portables de petites dimensions tels que des téléphones intelligents et leur actionnement sert souvent à remettre à zéro les circuits électroniques du téléphone.Push buttons of the type described above are also found on other small portable objects such as smartphones and their actuation is often used to reset the electronic circuits of the phone.

Résumé de l'inventionSummary of the invention

La présente invention a pour but de remédier aux problèmes susmentionnés ainsi qu'à d'autres encore en procurant un outil pouvant être utilisé par les horlogers, mais avant tout destiné aux porteurs de montres et permettant d'actionner de petits boutons-poussoirs encore appelés correcteurs sans risque de blesser la carrure de la boîte de montre.The present invention aims to remedy the aforementioned problems as well as others by providing a tool which can be used by watchmakers, but above all intended for watch wearers and which makes it possible to activate small push buttons also called correctors without the risk of damaging the middle of the watch case.

A cet effet, la présente invention concerne un outil d'actionnement selon la revendication 1 annexée.For this purpose, the present invention relates to an actuation tool according to appended claim 1.

Selon des formes particulières de réalisation de l'invention :

  • le corps comprend une coiffe agencée de manière fixe sur la tige d'actionnement, le manchon de guidage étant disposé entre la coiffe et la tige d'actionnement du côté de l'extrémité avant du corps ;
  • la coiffe délimite avec la tige d'actionnement un logement cylindrique à l'intérieur duquel le manchon de guidage, disposé de manière coaxiale autour de la tige d'actionnement, est apte à se déplacer d'avant en arrière et d'arrière en avant sous l'effet d'un ressort hélicoïdal enfilé sur la tige d'actionnement ;
  • le ressort hélicoïdal prend appui contre le manchon de guidage du côté de l'extrémité avant, et contre un épaulement formé sur la tige d'actionnement du côté de l'extrémité arrière ;
  • la portion d'actionnement de la tige d'actionnement fait saillie de la coiffe, le manchon de guidage étant mobile entre une position sortie de repos dans laquelle une portion terminale de celui-ci entoure complètement la portion d'actionnement de la tige d'actionnement, et une position rentrée de travail dans laquelle la portion terminale est rétractée à l'intérieur de la coiffe ;
  • la tige d'actionnement comprend une première portion cylindrique avec un premier diamètre et une deuxième portion cylindrique avec un deuxième diamètre inférieur au premier diamètre, la portion d'actionnement étant formée par une troisième portion cylindrique avec un troisième diamètre inférieur au deuxième diamètre, la coiffe étant agencée fixement sur la deuxième portion cylindrique de la tige d'actionnement et délimitant avec la troisième portion cylindrique de la tige d'actionnement le logement cylindrique à l'intérieur duquel le manchon de guidage est disposé de manière coaxiale autour de la troisième portion cylindrique de la tige d'actionnement, le ressort hélicoïdal étant enfilé sur la troisième portion cylindrique de la tige d'actionnement et prenant appui contre le manchon de guidage à une extrémité avant, et contre un épaulement formé par la deuxième portion cylindrique de la tige d'actionnement à une extrémité arrière, la troisième portion cylindrique faisant saillie de la coiffe à l'extrémité avant de l'outil d'actionnement et étant entourée par la portion terminale du manchon de guidage qui est également cylindrique.
According to particular embodiments of the invention:
  • the body comprises a cap fixedly arranged on the actuation rod, the guide sleeve being disposed between the cap and the actuation rod on the front end side of the body;
  • the cap defines with the actuating rod a cylindrical housing inside which the guide sleeve, arranged coaxially around the actuating rod, is able to move back and forth and back to front under the effect of a helical spring threaded onto the actuating rod;
  • the helical spring bears against the guide sleeve on the front end side, and against a shoulder formed on the actuating rod on the rear end side;
  • the actuation portion of the actuation rod projects from the cap, the guide sleeve being movable between a rest extended position in which a terminal portion thereof completely surrounds the actuation portion of the actuation rod actuation, and a retracted working position in which the terminal portion is retracted inside the cap;
  • the actuation rod comprises a first cylindrical portion with a first diameter and a second cylindrical portion with a second diameter less than the first diameter, the actuation portion being formed by a third cylindrical portion with a third diameter less than the second diameter, the cap being arranged fixedly on the second cylindrical portion of the actuating rod and delimiting with the third cylindrical portion of the actuating rod the cylindrical housing inside which the guide sleeve is arranged coaxially around the third portion cylindrical portion of the actuating rod, the helical spring being threaded onto the third cylindrical portion of the actuating rod and bearing against the guide sleeve at a front end, and against a shoulder formed by the second cylindrical portion of the rod actuation tool at a rear end, the third cylindrical portion projecting from the cap at the front end of the actuation tool and being surrounded by the end portion of the guide sleeve which is also cylindrical.

Grâce à ces caractéristiques, la présente invention procure un outil qui permet d'actionner des boutons-poussoirs du type correcteurs, c'est-à-dire noyés dans une carrure d'une montre, notamment une montre à grandes complications, sans risquer de blesser la carrure de l'objet portable. En effet, au repos, la tige d'actionnement se trouve dans une situation dans laquelle son extrémité avant qui définit une portion d'actionnement d'un correcteur se trouve tout au plus en affleurement par rapport à un manchon de guidage qui l'entoure. Par conséquent, lorsque l'on veut actionner un correcteur au moyen de l'outil d'actionnement selon l'invention, on approche cet outil du correcteur et on l'applique par son manchon correcteur contre la carrure de l'objet portable. Il n'y a donc, à ce stade, aucun risque de blesser la carrure de l'objet portable puisque la portion d'actionnement est en retrait ou tout au plus en affleurement par rapport au manchon de guidage. Puis, une fois l'outil d'actionnement appuyé contre la carrure de l'objet portable, on exerce sur cet outil une légère poussée, ce qui a pour effet de faire passer le manchon de guidage de sa première position dans laquelle il entoure la portion d'actionnement de la tige d'actionnement à sa seconde position, au moins partiellement rentrée à l'intérieur du corps, dans laquelle la portion d'actionnement est apte à actionner le bouton-poussoir correcteur. Une fois le correcteur actionné, on relâche la pression sur l'outil d'actionnement, ce qui a pour effet de permettre au manchon de guidage de retourner dans sa première position dans laquelle il entoure complètement la portion d'actionnement de la tige d'actionnement.Thanks to these characteristics, the present invention provides a tool which makes it possible to activate push buttons of the corrector type, that is to say embedded in the middle of a watch, in particular a watch with large complications, without risking damage. injure the frame of the portable object. Indeed, at rest, the actuating rod is in a situation in which its front end which defines an actuation portion of a corrector is at most flush with a guide sleeve which surrounds it. . Consequently, when we want to actuate a corrector by means of the actuation tool according to the invention, we approach this tool of the corrector and we apply it by its corrector sleeve against the middle of the portable object. There is therefore, at this stage, no risk of injuring the middle of the portable object since the actuation portion is recessed or at most flush with the guide sleeve. Then, once the actuation tool is pressed against the middle of the portable object, a slight push is exerted on this tool, which has the effect of moving the guide sleeve from its first position in which it surrounds the actuation portion of the actuation rod in its second position, at least partially retracted inside the body, in which the actuation portion is capable of actuating the corrective push button. Once the corrector is actuated, the pressure is released on the actuation tool, which has the effect of allowing the guide sleeve to return to its first position in which it completely surrounds the actuation portion of the rod. actuation.

Selon un autre avantage de l'invention, la fonction de guidage de l'outil, assurée par le manchon de guidage qui entoure la tige d'actionnement et qui vient en appui contre le pourtour extérieur du bouton-poussoir correcteur, est séparée de la fonction d'actionnement proprement dite de l'outil qui est réalisée par la tige d'actionnement, ce qui facilite grandement le positionnement et l'utilisation de l'outil d'actionnement.According to another advantage of the invention, the function of guiding the tool, provided by the guide sleeve which surrounds the actuating rod and which bears against the outer periphery of the corrective push button, is separated from the actual actuation function of the tool which is carried out by the actuation rod, which greatly facilitates the positioning and use of the actuation tool.

On a donc compris que la portion d'actionnement qui constitue l'élément actif de l'outil d'actionnement passe d'un état de repos dans lequel elle est entourée par le manchon de guidage, à un état de travail dans lequel elle permet d'actionner le correcteur. La tige d'actionnement, et donc la portion d'actionnement, sont fixes, et le manchon de guidage est mobile entre une position sortie de repos dans laquelle sa portion terminale entoure complètement la portion d'actionnement de la tige d'actionnement, et une position de travail au moins partiellement rangée dans laquelle la portion d'actionnement de la tige d'actionnement est dégagée.We have therefore understood that the actuation portion which constitutes the active element of the actuation tool passes from a rest state in which it is surrounded by the guide sleeve, to a working state in which it allows to activate the corrector. The actuation rod, and therefore the actuation portion, are fixed, and the guide sleeve is movable between a rest extended position in which its terminal portion completely surrounds the actuation portion of the actuation rod, and a working position at least partially stored in which the actuation portion of the actuation rod is disengaged.

La présente invention procède de l'idée générale inventive qui consiste à procurer un outil d'actionnement permettant d'actionner un bouton-poussoir du type correcteur noyé dans la carrure d'un objet portable tel qu'une montre-bracelet à complications sans risquer de blesser la carrure de l'objet portable qui, en particulier dans le cas des montres-bracelets, est très souvent réalisée en un matériau précieux. Pour atteindre cet objectif, la présente invention enseigne d'utiliser un outil d'actionnement dont la portion active est entourée d'un manchon de guidage en position de repos. On peut ainsi positionner l'outil d'actionnement face au bouton-poussoir correcteur sans risque de blesser la carrure de l'objet portable. Une fois l'outil convenablement positionné face au bouton-poussoir correcteur, on exerce une légère poussée sur l'outil correcteur, ce qui provoque un retrait au moins partiel du manchon de guidage à l'intérieur du corps de l'outil d'actionnement et permet à la portion active de l'outil d'actionnement de corriger le bouton-poussoir correcteur.The present invention proceeds from the general inventive idea which consists of providing an actuation tool making it possible to actuate a corrector type push button embedded in the middle of a portable object such as a wristwatch complications without risking injury to the case of the wearable object which, particularly in the case of wristwatches, is very often made of a precious material. To achieve this objective, the present invention teaches the use of an actuation tool whose active portion is surrounded by a guide sleeve in the rest position. It is thus possible to position the actuation tool facing the corrective push-button without risk of injuring the middle of the portable object. Once the tool is properly positioned in front of the correcting push button, a slight push is exerted on the correcting tool, which causes at least partial withdrawal of the guide sleeve inside the body of the actuating tool and allows the active portion of the actuation tool to correct the corrective push button.

La figure 1 est une vue en perspective d'un mode de réalisation d'un bouton-poussoir de type correcteur dont l'actionnement peut être effectué au moyen d'un outil d'actionnement selon l'invention. On comprendra cependant que la description d'un tel bouton-poussoir correcteur est donnée à titre purement illustratif et nullement limitatif seulement. Il s'agit d'un bouton-poussoir correcteur de type conventionnel dont la structure n'a nullement besoin d'être modifiée ou adaptée en fonction de la structure de l'outil d'actionnement selon l'invention. Inversement, les caractéristiques des boutons-poussoirs correcteurs n'influent pas l'agencement de l'outil d'actionnement selon l'invention.There figure 1 is a perspective view of an embodiment of a corrector type push button which can be actuated by means of an actuation tool according to the invention. It will be understood, however, that the description of such a correction push button is given for purely illustrative purposes and is in no way limiting. This is a conventional type corrective push button whose structure does not need to be modified or adapted depending on the structure of the actuation tool according to the invention. Conversely, the characteristics of the corrective push buttons do not influence the arrangement of the actuation tool according to the invention.

Désigné dans son ensemble par la référence numérique générale 1, un bouton-poussoir de type correcteur comprend classiquement une douille 2 par exemple chassée ou collée dans une ouverture 4 pratiquée dans une carrure 6 d'un objet portable, par exemple une montre-bracelet dont la carrure est réalisée dans un matériau précieux. Ce bouton-poussoir correcteur 1 peut être actionné par l'utilisateur au moyen d'un outil pointu 5.Designated as a whole by the general numerical reference 1, a corrector type push button conventionally comprises a socket 2 for example driven or stuck in an opening 4 made in a middle part 6 of a portable object, for example a wristwatch including the middle is made of a precious material. This corrective push button 1 can be actuated by the user using a pointed tool 5.

Une tige de commande 8 cylindrique est apte à coulisser dans la douille 2. La douille 2 comprend à cet effet un premier passage cylindrique 10a qui débouche du côté extérieur de la carrure 6 de l'objet portable et qui est adapté aux dimensions d'une première portion 12a de la tige de commande 8. Du côté intérieur de la carrure 6, la douille 2 comprend un second passage cylindrique 10b agencé dans le prolongement du premier passage cylindrique 10a et qui définit un épaulement 11 à l'intérieur de la douille 2. Le diamètre intérieur de ce second passage cylindrique 10b, adapté aux dimensions d'une seconde portion 12b de la tige de commande 8, est inférieur à celui du premier passage cylindrique 10a. Une garniture d'étanchéité 14 logée dans une saignée ménagée sur un périmètre de la première portion 12a de la tige de commande 8 permet de garantir l'étanchéité entre la tige de commande 8 et la douille 2. Un tel bouton-poussoir correcteur 1 comprend également un ressort hélicoïdal 16 qui se comprime lorsque l'utilisateur appuie sur le bouton-poussoir correcteur 1, et dont la force de rappel ramène la tige de commande 8 en position de repos lorsque l'utilisateur relâche la pression sur le bouton-poussoir correcteur 1. Le ressort hélicoïdal 16 est en appui contre une rondelle 18 montée fixe sur la première portion 12a de la tige de commande 8 à une extrémité, et contre l'épaulement 11 à l'autre extrémité.A cylindrical control rod 8 is able to slide in the socket 2. The socket 2 comprises for this purpose a first cylindrical passage 10a which opens out on the exterior side of the middle part 6 of the portable object and which is adapted to the dimensions of a first portion 12a of the control rod 8. On the inner side of the middle part 6, the socket 2 comprises a second cylindrical passage 10b arranged in the extension of the first cylindrical passage 10a and which defines a shoulder 11 inside the socket 2 The internal diameter of this second cylindrical passage 10b, adapted to the dimensions of a second portion 12b of the control rod 8, is less than that of the first cylindrical passage 10a. A sealing gasket 14 housed in a groove formed on a perimeter of the first portion 12a of the control rod 8 makes it possible to guarantee the seal between the control rod 8 and the socket 2. Such a corrective push button 1 comprises also a helical spring 16 which compresses when the user presses the corrector push-button 1, and whose return force returns the control rod 8 to the rest position when the user releases the pressure on the corrector push-button 1. The helical spring 16 bears against a washer 18 fixedly mounted on the first portion 12a of the control rod 8 at one end, and against the shoulder 11 at the other end.

Des boutons-poussoirs du type décrit ci-dessus ont des dimensions très réduites. Ils permettent donc de gagner de la place. En outre, ils ne font pas saillie de la carrure et ne risquent donc pas d'être actionnés involontairement. De tels boutons-poussoirs équipent fréquemment des montres haut de gamme dites à complications. Les opérations de correction se font au moyen d'un instrument pointu tel qu'un stylo par exemple. Ce dernier point pose cependant problème. En effet, les montres-bracelets à complications sont des montres extrêmement onéreuses dont les boîtes de montres sont très souvent réalisées à l'aide de matériaux précieux. Or, les risques de blesser la boîte de la montre et d'altérer son aspect esthétique lorsqu'on manipule un instrument pointu sont importants, ce qui est devenu difficilement acceptable.Push buttons of the type described above have very small dimensions. They therefore save space. In addition, they do not protrude from the middle and are therefore not likely to be activated unintentionally. Such push buttons are frequently fitted to high-end so-called complication watches. Correction operations are carried out using a pointed instrument such as a pen for example. This last point, however, poses a problem. Indeed, complicated wristwatches are extremely expensive watches whose watch cases are very often made using precious materials. However, the risks of damaging the watch case and altering its aesthetic appearance when handling a sharp instrument are important, which has become difficult to accept.

Pour pallier ce problème, la présente invention procure un outil d'actionnement pour un bouton-poussoir correcteur dont un mode de réalisation est illustré aux figures 2A et 2B. Désigné dans son ensemble par la référence numérique générale 20, l'outil d'actionnement comprend un corps 22 de forme générale non limitativement cylindrique qui s'étend entre une extrémité arrière 24 qui définit une zone de préhension de l'outil d'actionnement 20, et une extrémité avant 26 qui définit une zone d'actionnement de l'outil d'actionnement 20.To overcome this problem, the present invention provides an actuation tool for a corrective push button, one embodiment of which is illustrated in Figures 2A and 2B . Designated as a whole by the general numerical reference 20, the actuation tool comprises a body 22 of general non-limitatively cylindrical shape which extends between a rear end 24 which defines a gripping zone of the actuation tool 20 , and a front end 26 which defines an actuation zone of the actuation tool 20.

L'outil d'actionnement 20 comprend également une tige d'actionnement 27 qui s'étend à l'intérieur du corps 22 et sur laquelle une coiffe 28 est agencée de manière fixe. Cette coiffe 28 délimite avec la tige d'actionnement 27 un logement cylindrique 30 à l'intérieur duquel un manchon de guidage 32, disposé de manière coaxiale autour de la tige d'actionnement 27, est apte à se déplacer d'avant en arrière et d'arrière en avant sous l'effet d'un ressort hélicoïdal 34 enfilé sur la tige d'actionnement 27. Comme on peut le voir sur les figures 2A et 2B, le ressort hélicoïdal 34 prend appui contre le manchon de guidage 32 à une extrémité avant 26, et contre un épaulement 36 formé sur la tige d'actionnement 27 à une extrémité arrière 24.The actuation tool 20 also comprises an actuation rod 27 which extends inside the body 22 and on which a cap 28 is fixedly arranged. This cap 28 delimits with the actuating rod 27 a cylindrical housing 30 inside which a guide sleeve 32, arranged coaxially around the actuating rod 27, is capable of moving back and forth and from back to front under the effect of a helical spring 34 threaded on the actuating rod 27. As can be seen on the Figures 2A and 2B , the helical spring 34 bears against the guide sleeve 32 at a front end 26, and against a shoulder 36 formed on the actuating rod 27 at a rear end 24.

Enfin, la tige d'actionnement 27 comprend à son extrémité avant une portion d'actionnement 38 qui fait saillie de la coiffe 28 à l'extrémité avant 26 de l'outil d'actionnement 20. Cette portion d'actionnement 38 constitue l'élément actif de l'outil d'actionnement 20 via lequel on actionne le bouton-poussoir correcteur 1. Quant au manchon de guidage 32, il est mobile entre une position sortie de repos (figure 2A) dans laquelle le manchon de guidage 32 est forcé vers l'extérieur de la coiffe 28 par le ressort hélicoïdal 34, et une position rentrée de travail (figure 2B) dans laquelle le manchon de guidage 32 est au moins en partie repoussé à l'intérieur de la coiffe 28 à l'encontre de la force élastique du ressort hélicoïdal 34. Comme on peut le voir à l'examen des figures 2A et 2B, une portion terminale 40 du manchon de guidage 32 entoure complètement la portion d'actionnement 38 de la tige d'actionnement 27 en position de repos, tandis que cette portion d'actionnement 38 est dégagée de la portion terminale 40 du manchon de guidage 32 en position rentrée de travail.Finally, the actuation rod 27 comprises at its front end an actuation portion 38 which projects from the cap 28 at the front end 26 of the actuation tool 20. This actuation portion 38 constitutes the active element of the actuation tool 20 via which the corrective push-button 1 is actuated. As for the guide sleeve 32, it is movable between a rest extended position ( Figure 2A ) in which the guide sleeve 32 is forced towards the outside of the cap 28 by the helical spring 34, and a retracted working position ( Figure 2B ) in which the guide sleeve 32 is at least partly pushed back inside the cap 28 against the elastic force of the helical spring 34. As can be seen on examination of the Figures 2A and 2B , an end portion 40 of the guide sleeve 32 completely surrounds the actuation portion 38 of the actuation rod 27 in the rest position, while this actuation portion 38 is released from the end portion 40 of the guide sleeve 32 in the working return position.

Plus précisément, lorsque l'outil d'actionnement 20 est au repos et que l'on souhaite actionner le bouton-poussoir correcteur 1, on commence à approcher cet outil d'actionnement 20 du bouton-poussoir correcteur 1 et on applique la portion terminale 40 du manchon de guidage 32 contre la carrure 6 de l'objet portable (figure 2A). Puis, sous l'effet d'une poussée exercée sur l'outil d'actionnement 20, le manchon de guidage 32 se rétracte à l'intérieur de la coiffe 28, ce qui permet de dégager la portion d'actionnement 38 et d'actionner le bouton-poussoir correcteur 1. Lorsque la correction a été effectuée, on retire l'outil d'actionnement 20 et, sous l'effet de la force de rappel élastique du ressort hélicoïdal 34, le manchon de guidage 32 sort à nouveau de la coiffe 28 et vient entourer la portion d'actionnement 38 de la tige d'actionnement 27.More precisely, when the actuation tool 20 is at rest and we wish to actuate the corrective push-button 1, we begin to approach this actuation tool 20 of the corrective push-button 1 and we apply the terminal portion 40 of the guide sleeve 32 against the middle part 6 of the portable object ( Figure 2A ). Then, under the effect of a thrust exerted on the actuation tool 20, the guide sleeve 32 retracts inside the cap 28, which makes it possible to release the actuation portion 38 and to actuate the corrector push-button 1. When the correction has been made, the actuation tool 20 is removed and, under the effect of the elastic return force of the helical spring 34, the guide sleeve 32 comes out again from the cap 28 and surrounds the actuation portion 38 of the actuation rod 27.

Selon une forme particulière de réalisation de l'invention illustrée aux figures 2A et 2B, la tige d'actionnement 27 comprend une première portion cylindrique 27a avec un premier diamètre, et une deuxième portion cylindrique 27b avec un deuxième diamètre inférieur au premier diamètre. Quant à la portion d'actionnement 38, elle est formée par une troisième portion cylindrique 27c avec un troisième diamètre inférieur au deuxième diamètre.According to a particular embodiment of the invention illustrated in Figures 2A and 2B , the actuating rod 27 comprises a first cylindrical portion 27a with a first diameter, and a second cylindrical portion 27b with a second diameter less than the first diameter. As for the actuation portion 38, it is formed by a third cylindrical portion 27c with a third diameter less than the second diameter.

Comme on peut le voir sur les figures, la coiffe 28 est agencée fixement, par exemple grâce à un filetage 42, sur la deuxième portion cylindrique 27b de la tige d'actionnement 27 et délimite avec la troisième portion cylindrique 27c de la tige d'actionnement 27 le logement cylindrique 30 à l'intérieur duquel le manchon de guidage 32 est disposé de manière coaxiale autour de la troisième portion cylindrique 27c de la tige d'actionnement 27.As can be seen in the figures, the cap 28 is fixedly arranged, for example thanks to a thread 42, on the second cylindrical portion 27b of the actuating rod 27 and delimits with the third cylindrical portion 27c of the actuating rod actuation 27 the cylindrical housing 30 inside which the guide sleeve 32 is arranged coaxially around the third cylindrical portion 27c of the actuating rod 27.

Le ressort hélicoïdal 34 est enfilé sur la troisième portion cylindrique 27c de la tige d'actionnement 27 et prend appui contre le manchon de guidage 32 à une extrémité avant, et contre l'épaulement 36 formé par la jonction entre la deuxième portion cylindrique 27b et la troisième portion cylindrique 27c de la tige d'actionnement 27 à une extrémité arrière. La troisième portion cylindrique 27c fait saillie de la coiffe 28 à l'extrémité avant 26 de l'outil d'actionnement 20 et est entourée par la portion terminale 40 du manchon de guidage 32 qui est également cylindrique.The helical spring 34 is threaded onto the third cylindrical portion 27c of the actuating rod 27 and bears against the guide sleeve 32 at a front end, and against the shoulder 36 formed by the junction between the second cylindrical portion 27b and the third cylindrical portion 27c of the actuating rod 27 at a rear end. The third cylindrical portion 27c projects from the cap 28 at the front end 26 of the actuation tool 20 and is surrounded by the end portion 40 of the guide sleeve 32 which is also cylindrical.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées. On comprendra en particulier que, dans l'exemple décrit ci-dessus, le manchon de guidage 32 se rétracte suffisamment à l'intérieur de la coiffe 28 en position de travail pour que la portion d'actionnement 38 de la tige d'actionnement 27 soit dégagée du manchon de guidage 32. Cette condition n'est cependant pas obligatoire et on comprendra qu'il suffit que la course du manchon de guidage 32 entre sa position sortie de repos et sa position au moins partiellement rentrée de travail soit suffisante pour que la tige d'actionnement 27 puisse actionner la tige de commande 8 du bouton-poussoir correcteur 1. On notera aussi que, selon un mode particulier de réalisation de l'invention, au moins l'extrémité de la portion d'actionnement 38 de la tige d'actionnement 27 sera revêtue d'une couche d'un matériau moins dur que le matériau dans lequel est par exemple réalisée la carrure 6 de l'objet portable. On notera enfin que, bien souvent, la tête des boutons-poussoirs correcteurs est entourée d'une rainure circulaire 44 (voir figures 2A et 2B) usinée dans la carrure 6 de l'objet portable. Selon un mode avantageux de réalisation de l'invention, le diamètre du manchon de guidage 32 correspondra au diamètre de la rainure circulaire 44.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various simple modifications and variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined. by the appended claims. It will be understood in particular that, in the example described above, the guide sleeve 32 retracts sufficiently inside the cap 28 in the working position so that the actuating portion 38 of the actuating rod 27 is released from the guide sleeve 32. This condition is however not obligatory and it will be understood that it is sufficient for the travel of the guide sleeve 32 between its extended rest position and its at least partially retracted working position to be sufficient for the actuation rod 27 can actuate the control rod 8 of the corrector push-button 1. It will also be noted that, according to a particular embodiment of the invention, at least the end of the actuation portion 38 of the actuating rod 27 will be coated with a layer of a material that is less hard than the material in which, for example, the middle part 6 of the portable object is made. Finally, note that, very often, the head of the correction push-buttons is surrounded by a circular groove 44 (see Figures 2A and 2B ) machined in the middle part 6 of the portable object. According to an advantageous embodiment of the invention, the diameter of the guide sleeve 32 will correspond to the diameter of the circular groove 44.
