Abstract

The invention relates to a reversible watch case (1), against which a removable element (2, 2') having the horns (3) of said case (1) is arranged on both sides. Each element (2, 2’) is rigidly connected to the watch case (1) by an indexing system arranged such that said removable element (2, 2') is lockable onto the watch case (1) in a first and second indexed position, respectively. The removable element (2, 2’) is also actuatable to pivot 180° around a journal (10, 10’) so as to pass from one indexed position to the other. Each indexed position of the removable element (2, 2’) in relation to the watch case (1) is obtained by the coupling of two male elements (9, 9’) with two female elements (8, 8’) arranged at 180° from each other relative to the rotational axis of the removable element (2, 2’) and sufficiently close to the journal (10, 10’) such that the movement of the female elements (8, 8') relative to the male elements (9, 9') describes the arc of a circle, the diameter of which does not exceed the thickness of the watch case, such that said male elements (9, 9') are preferably capable of making permanent contact with a circular flat section (13) located on the watch case (1) around the journal (10, 10’) during the 180° rotation needed by said removable element (2, 2’) in relation to the watch case (1) to pass from one indexed position to the other.

Description

MONTRE-BRACELET REVERSIBLE REVERSIBLE BRACELET WATCH
La présente invention est relative au domaine de l'horlogerie, plus particulièrement à un mécanisme de réversibilité d'une boîte de montre par rapport à un bracelet.The present invention relates to the field of watchmaking, more particularly to a reversibility mechanism of a watch case with respect to a bracelet.
D'innombrables dispositifs permettant la réversibilité d'une boîte de montre par rapport à un bracelet font déjà partie de l'état de la technique. La majorité de ces dispositifs sont complexes et dénaturent l'esthétisme de la montre.Countless devices allowing the reversibility of a watch case with respect to a bracelet are already part of the state of the art. The majority of these devices are complex and distort the aesthetics of the watch.
Néanmoins, il existe certaines montres comportant un dispositif de réversibilité dont les éléments constitutifs du mécanisme n'altèrent pas la sobriété de la montre.Nevertheless, there are certain watches including a reversibility device whose constituent elements of the mechanism do not alter the sobriety of the watch.
La publication EP1902641 divulgue une montre-bracelet à boîtier réversible contre lequel est agencé de part et d'autre un élément amovible possédant les cornes de la boîte de montre. Ces éléments amovibles sont montés pivotant et coulissant sur ladite boîte par l'intermédiaire d'un tourillon. Celui-ci comprend une première et une seconde encoches transversales décalées longitudinalement qui coopèrent par emboîtement avec une première et une seconde lames déformables élastiquement de manière à indexer l'élément amovible respectivement en position de repos et en position de pivotement. Ces deux lames sont obtenues par une fente longitudinale effectuée sur une lame rectangulaire principale à sa mi-hauteur. Les extrémités de cette lame principale sont fixées sur la carrure à l'intérieur de la boîte de montre.The publication EP1902641 discloses a reversible case wristwatch against which is arranged on either side a removable element having the horns of the watch case. These removable elements are pivotally mounted and sliding on said box by means of a trunnion. This comprises first and second longitudinally offset transverse notches which cooperate by interlocking with a first and a second elastically deformable blades so as to index the removable element respectively in the rest position and in the pivoting position. These two blades are obtained by a longitudinal slit performed on a main rectangular blade at its mid-height. The ends of this main blade are attached to the middle part of the watch case.
Néanmoins, ce système d'indexation est adapté pour un dispositif de réversibilité qui joue sur la déformation élastique des deux lames puisque les extrémités de la lame principale sont vissées sur la carrure de la boîte de montre. Par conséquent, l'élément amovible doit non seulement être tiré pour que celui-ci se retrouve dans une position indexée de pivotement, mais aussi repoussé par le porteur de la montre pour que l'élément amovible soit à nouveau dans une position indexée de repos. Il en résulte des contraintes importantes exercées sur les lames déformables élastiquement ce qui peut entrainer à la longue la détérioration des propriétés mécaniques de ces lames. Afin de résoudre cette problématique, PCT/IB2007/053552, non encore publié, propose une boîte de montre réversible contre laquelle est agencée de part et d'autre l'élément amovible possédant les cornes de la dite boîte. Chaque élément amovible est solidaire de la boîte de montre par l'intermédiaire d'une lame flexible dont les extrémités sont, contrairement à EP1902641 , libres pour pouvoir se déplacer le long de la carrure lorsqu'une traction est exercée par le porteur sur l'élément amovible. Le système d'indexation de ce système de réversibilité comporte une ouverture de forme oblongue qui est agencée de part et d'autre de la boîte de montre. Un méplat circulaire est réalisé autour de cette ouverture. Chacune de ces ouvertures oblongues est destinée à recevoir un ergot de forme oblongue solidaire de chaque élément amovible, ledit ergot étant centré par rapport à l'axe de rotation de l'élément amovible. Les extrémités de la lame exercent une certaine contrainte sur la circonférence interne de la boîte de montre en leurs points d'appui lorsque l'ergot est agencé à l'intérieur de l'ouverture oblongue.Nevertheless, this indexing system is adapted for a reversibility device that plays on the elastic deformation of the two blades since the ends of the main blade are screwed to the middle part of the watch case. Therefore, the removable element must not only be pulled so that it is found in an indexed position of pivoting, but also pushed by the wearer of the watch so that the removable element is again in an indexed position of rest . This results in significant stresses exerted on the elastically deformable blades which can cause in the long term the deterioration of the mechanical properties of these blades. In order to solve this problem, PCT / IB2007 / 053552, not yet published, proposes a reversible watch case against which is arranged on either side the removable element having the horns of said box. Each removable element is secured to the watch case by means of a flexible blade whose ends are, unlike EP1902641, free to move along the middle when traction is exerted by the wearer on the removable element. The indexing system of this reversibility system comprises an oblong opening which is arranged on either side of the watch case. A circular flat is made around this opening. Each of these oblong openings is intended to receive an elongate pin integral with each removable element, said lug being centered relative to the axis of rotation of the removable element. The ends of the blade exert a certain stress on the inner circumference of the watch case at their fulcrums when the pin is arranged inside the oblong opening.
La réversibilité de la boîte de montre est obtenue par le pivotement de l'élément amovible de 180° selon l'axe perpendiculaire à l'axe central de ladite boîte. Cela est rendu possible lorsque le porteur de la montre tire sur l'extrémité du bracelet connecté à l'élément amovible afin de fléchir la lame ressort pour désengager l'ergot de l'ouverture. Une rotation de l'élément amovible peut alors être réalisée selon un axe perpendiculaire à l'axe central de la boîte de montre. Au cours de cette rotation, la surface de l'ergot de l'élément amovible est en contact permanent avec un méplat de forme circulaire situé autour de l'ouverture. Après une rotation de 180°, l'ergot se retrouve en correspondance avec l'ouverture oblongue et, sous l'action de la lame ressort, vient se loger à nouveau dans l'ouverture. L'élément amovible se retrouve ainsi verrouillé à la boîte de montre.The reversibility of the watch case is obtained by pivoting the removable element by 180 ° along the axis perpendicular to the central axis of said box. This is made possible when the wearer of the watch pulls on the end of the bracelet connected to the removable element to bend the spring blade to disengage the lug from the opening. A rotation of the removable element can then be performed along an axis perpendicular to the central axis of the watch case. During this rotation, the surface of the lug of the removable element is in constant contact with a flattened flat located around the opening. After a rotation of 180 °, the lug is found in correspondence with the oblong opening and, under the action of the spring blade, is housed again in the opening. The removable element is thus locked to the watch case.
La forme oblongue de l'ouverture et de l'ergot n'est toutefois pas la plus adaptée lorsque l'on désire incorporer un système d'étanchéité.The oblong shape of the opening and the lug is however not the most suitable when it is desired to incorporate a sealing system.
Ainsi, le but de la présente invention est de proposer une montre-bracelet réversible comportant un système d'indexation amélioré afin de résoudre les inconvénients susmentionnés. Conformément à l'invention, ce but est atteint grâce à une boîte de montre réversible selon la revendication 1 contre laquelle est agencé de part et d'autre un élément amovible possédant les cornes de ladite boîte. La boîte de montre de l'invention est du type dans lequel chaque élément amovible est rendu solidaire à la boîte de montre par un système d'indexation agencé de manière à ce que ledit élément amovible puisse être verrouillé à la boîte de montre dans respectivement une première et une seconde position indexées. L'élément amovible est en outre susceptible d'être actionné pour pivoter en son centre de 180° selon un axe perpendiculaire à l'axe central de la boîte de montre afin de passer de l'une des positions indexées à l'autre. Chaque élément amovible comporte un côté d'appui qui est susceptible d'être maintenu contre une partie située sur le contour de la boîte de montre par l'intermédiaire d'un organe élastique ou déformable. Celui-ci est agencé à l'intérieur de la carrure de la boîte de montre réversible et connecté à l'élément amovible par l'intermédiaire d'un tourillon monté au travers d'une ouverture agencée en correspondance avec l'axe de rotation de l'élément amovible. Ce dernier est susceptible d'être dégagé de l'une ou l'autre de ses positions stables afin de permettre sa rotation de 180° selon l'axe perpendiculaire à l'axe central de la boîte de montre. Chaque position indexée de l'élément amovible par rapport à la boîte de montre est obtenue par l'accouplement d'un élément mâle dans un élément femelle du système d'indexation, l'un des éléments étant situé sur la boîte de montre, l'autre des éléments étant situé sur le côté d'appui de l'élément amovible.Thus, the object of the present invention is to provide a reversible wristwatch with an improved indexing system to solve the aforementioned drawbacks. According to the invention, this object is achieved through a reversible watch case according to claim 1 against which is arranged on either side a removable element having the horns of said box. The watch case of the invention is of the type in which each removable element is secured to the watch case by an indexing system arranged so that said removable element can be locked to the watch case in respectively a first and second indexed positions. The removable element is furthermore capable of being actuated to pivot at its center 180 ° along an axis perpendicular to the central axis of the watch case in order to move from one of the indexed positions to the other. Each removable element comprises a support side which is capable of being held against a portion located on the contour of the watch case by means of an elastic or deformable member. This is arranged inside the middle of the reversible watch case and connected to the removable element via a pin mounted through an opening arranged in correspondence with the axis of rotation of the the removable element. The latter is likely to be released from one or other of its stable positions to allow its rotation of 180 ° along the axis perpendicular to the central axis of the watch case. Each indexed position of the removable element relative to the watch case is obtained by coupling a male element in a female element of the indexing system, one of the elements being located on the watch case, the other elements being located on the support side of the removable element.
Le système d'indexation comporte en outre un élément femelle additionnel agencé en correspondance avec l'élément mâle lorsque l'élément amovible se trouve dans l'une des positions indexées et, cas échéant, un élément mâle additionnel agencé en correspondance avec l'élément femelle additionnel lorsque l'élément amovible se trouve dans l'autre des positions indexées. L'élément femelle et l'élément femelle additionnel ainsi que le ou les éléments mâles correspondants sont agencés non pas sur le tourillon mais de part et d'autre de celui-ci de manière à ce que ce dernier puisse revêtir une forme cylindrique autour de laquelle et le cas échéant autour du ou des éléments mâles peut être ajusté un O-ring pour assurer l'étanchéité de la montre de manière simple et fiable. Les éléments mâles sont néanmoins agencés suffisamment proche du tourillon de manière à ce qu'ils puissent être toujours en contact avec la boîte de montre durant la rotation de l'élément amovible. Ainsi, il en résulte une boîte de montre dont la réversibilité est fiable et n'implique pas de contraintes excessives. Par ailleurs, le système de réversibilité facilite l'étanchéité de la montre.The indexing system further comprises an additional female element arranged in correspondence with the male element when the removable element is in one of the indexed positions and, if appropriate, an additional male element arranged in correspondence with the element. additional female when the removable element is in the other indexed positions. The female element and the additional female element as well as the corresponding male element or elements are arranged not on the trunnion but on both sides of the trunnion so that the latter can take a cylindrical shape around which and where appropriate around the male element or elements can be adjusted an O-ring to ensure the sealing of the watch simply and reliably. The male elements are nevertheless arranged sufficiently close to the trunnion so that they can always be in contact with the watch case during the rotation of the removable element. Thus, the result is a watch case whose reversibility is reliable and does not involve excessive constraints. In addition, the reversibility system facilitates the sealing of the watch.

Selon le mode préférentiel d'exécution de la présente invention, la montre-bracelet comporte une boîte de montre (1 ) et deux éléments amovibles (2, 2') sur lesquels sont agencés les cornes (3) de la montre.According to the preferred embodiment of the present invention, the wristwatch comprises a watch case (1) and two removable elements (2, 2 ') on which are arranged the horns (3) of the watch.
Chaque élément amovible (2, 2') est solidaire de la boîte de montre (1 ) par des moyens de fixation, dont les caractéristiques techniques seront décrites ultérieurement, agencés de manière à ce que ledit élément (2, 2') puisse être verrouillé à la boîte de montre (1 ) dans respectivement une première et une seconde position indexée. L'élément amovible (2, 2') est par ailleurs susceptible d'être actionné pour pivoter en son centre de 180° selon un axe perpendiculaire à l'axe central de la boîte de montre (1 ) autour d'un tourillon (10, 10') afin de passer de l'une des positions indexées à l'autre.Each removable element (2, 2 ') is secured to the watch case (1) by fixing means, whose technical characteristics will be described later, arranged so that said element (2, 2') can be locked at the watch case (1) in respectively a first and a second indexed position. The removable element (2, 2 ') is moreover susceptible to be actuated to pivot in its center of 180 ° along an axis perpendicular to the central axis of the watch case (1) around a pin (10, 10 ') in order to pass from one of the indexed positions to the other.
La boîte de montre (1 ) possède sur sa circonférence externe deux parties (5) diamétralement opposées et rectifiées afin que le rayon de courbure de chaque partie (5) soit légèrement inférieur au rayon de courbure de la circonférence externe de la boîte de montre (1 ). Chaque élément amovible (2, 2') possède un côté concave (4) identique au rayon de courbure de chaque partie rectifiée (5) afin de pouvoir être agencé pour épouser parfaitement le contour de ladite partie (5). L'épaisseur de l'élément amovible (2, 2') est déterminée de manière à ce que ce dernier puisse se confondre avec la circonférence externe de la boîte de montre (1 ) lorsque ces éléments amovibles (2, 2') sont indexés.The watch case (1) has on its outer circumference two portions (5) diametrically opposed and rectified so that the radius of curvature of each portion (5) is slightly less than the radius of curvature of the outer circumference of the watch case ( 1). Each removable element (2, 2 ') has a concave side (4) identical to the radius of curvature of each ground part (5) in order to be able to fit perfectly the contour of said part (5). The thickness of the removable element (2, 2 ') is determined in such a way that the latter can merge with the outer circumference of the watch case (1) when these removable elements (2, 2') are indexed .
Le verrouillage de l'élément amovible (2, 2') contre la partie rectifiée (5) de la boîte de montre (1 ) est assuré d'une part, par l'intermédiaire d'une lame flexible (6) agencée à l'intérieur de la carrure de ladite boîte (1 ) et dont les extrémités sont en appui contre la circonférence interne de la boîte de montre (1 ) (Figure 2a et 2b) et d'autre part, par un système d'indexation.Locking of the removable element (2, 2 ') against the ground part (5) of the watch case (1) is provided on the one hand by means of a flexible blade (6) arranged on the inside the middle of said box (1) and whose ends bear against the inner circumference of the watch case (1) (Figure 2a and 2b) and secondly by an indexing system.
Le tourillon (10, 10') est constitué d'une part, d'une partie cylindrique (10) comportant un taraudage, ladite partie cylindrique (10) étant agencée au centre de la partie concave (4) de l'élément amovible (2, 2') et d'autre part, d'un plot de pivotement cylindrique (10') vissé à l'intérieur de la partie cylindrique (10). La lame flexible (6) comporte un alésage (1 1 ) en son milieu à l'intérieur duquel est agencé puis fixé par l'intermédiaire d'une clavette (12) le plot de pivotement (10) afin de rendre solidaire ladite lame (6) à l'élément amovible (2, 2').The trunnion (10, 10 ') is constituted on the one hand by a cylindrical part (10) having a tapping, said cylindrical part (10) being arranged at the center of the concave part (4) of the removable element ( 2, 2 ') and on the other hand, a cylindrical pivoting stud (10') screwed inside the cylindrical part (10). The flexible blade (6) has a bore (1 1) in its middle inside which is arranged and then fixed by means of a key (12) the pivot pin (10) to make said blade ( 6) to the removable element (2, 2 ').
Le système d'indexation comporte deux orifices circulaires (8, 8') agencés à 180° l'un de l'autre par rapport à l'axe de rotation de l'élément amovible (2, 2') et deux ergots circulaires (9, 9') agencés en correspondance de part et d'autre de la partie inférieure du tourillon (10, 10') sur le côté concave (4) de l'élément amovible (2, 2'). Les deux ergots (9, 9') sont agencés suffisamment proche du tourillon (10, 10') afin que le déplacement relatif des deux orifices circulaires (8, 8') par rapport aux ergots (9, 9') décrive un arc de cercle dont le diamètre n'excède pas la hauteur de la partie rectifiée (5) de la boîte de montre (1 ).The indexing system comprises two circular orifices (8, 8 ') arranged at 180 ° to each other with respect to the axis of rotation of the removable element (2, 2') and two circular lugs ( 9, 9 ') arranged in correspondence on either side of the lower part of the journal (10, 10') on the concave side (4) of the removable element (2, 2 '). The two lugs (9, 9 ') are arranged sufficiently close to the journal (10, 10') so that the relative displacement of the two circular orifices (8, 8 ') with respect to the lugs (9, 9 ') describes an arc whose diameter does not exceed the height of the ground portion (5) of the watch case (1).
Un méplat de forme circulaire (13) dont le diamètre équivaut approximativement à la hauteur de ladite partie rectifiée (5) est agencé autour de chaque tourillon (10, 10') de part et d'autre de la boîte de montre réversible (1 ).A circularly shaped flat (13) whose diameter is approximately equal to the height of said ground portion (5) is arranged around each pin (10, 10 ') on either side of the reversible watch case (1) .
Les extrémités de la lame (6) exercent une certaine contrainte sur la circonférence interne de la boîte de montre (1 ) en leurs points d'appui lorsque les deux ergots (9, 9') sont agencés dans les orifices (8, 8') afin que l'élément amovible (2, 2') soit maintenu fermement contre la partie (5) de la boîte de montre (1 ).The ends of the blade (6) exert a certain stress on the inner circumference of the watch case (1) at their bearing points when the two lugs (9, 9 ') are arranged in the orifices (8, 8'). ) so that the removable element (2, 2 ') is firmly held against the part (5) of the watch case (1).
La réversibilité de la boîte de montre (1 ) est obtenue par le pivotement de l'élément amovible (2, 2') de 180° selon l'axe perpendiculaire à l'axe central de ladite boîte (1 ). Cela est rendu possible lorsque le porteur de la montre tire sur l'extrémité du bracelet connecté à l'élément amovible (2, 2') afin de fléchir la lame ressort (6) pour désengager les ergots (9, 9') des orifices (8, 8'). Une rotation de l'élément amovible (2, 2') peut alors être réalisée selon un axe perpendiculaire à l'axe central de la boîte de montre (1 ). Au cours de cette rotation, la surface des ergots (9, 9') de l'élément amovible (2, 2') est en contact permanent avec le méplat circulaire (13) assurant ainsi une indexation longitudinale selon l'axe du tourillon (10, 10').The reversibility of the watch case (1) is obtained by pivoting the removable element (2, 2 ') by 180 ° along the axis perpendicular to the central axis of said box (1). This is made possible when the wearer of the watch pulls on the end of the bracelet connected to the removable element (2, 2 ') in order to bend the spring blade (6) to disengage the lugs (9, 9') from the orifices. (8, 8 '). A rotation of the removable element (2, 2 ') can then be performed along an axis perpendicular to the central axis of the watch case (1). During this rotation, the surface of the lugs (9, 9 ') of the removable element (2, 2') is in permanent contact with the circular flattening surface (13) thus ensuring longitudinal indexing along the axis of the trunnion ( 10, 10 ').
Après une rotation de 180°, les deux ergots (9, 9') se retrouvent en correspondance avec les orifices (8, 8') et, sous l'action de la lame ressort (6), viennent se loger à nouveau dans ces orifices (8, 8'). L'élément amovible (2, 2') se retrouve ainsi verrouillé à la boîte de montre (1 ).After a rotation of 180 °, the two lugs (9, 9 ') are found in correspondence with the orifices (8, 8') and, under the action of the leaf spring (6), are housed again in these orifices (8, 8 '). The removable element (2, 2 ') is thus locked to the watch case (1).
Afin d'assurer l'étanchéité de la montre, un O-ring (14) est agencé autour des deux ergots (9, 9') et de la partie cylindrique (10) du tourillon (10, 10').In order to seal the watch, an O-ring (14) is arranged around the two lugs (9, 9 ') and the cylindrical portion (10) of the pin (10, 10').
II va de soit que l'invention n'est pas limitée aux modes d'exécution décrits ci- dessus à titre d'exemples mais qu'elle embrasse, au contraire toutes les variantes d'exécution. Par exemple, la forme de la boîte de montre réversible (1 ) peut être ovale ou encore rectangulaire. It goes without saying that the invention is not limited to the embodiments described above as examples but embraces, on the contrary, all variants of execution. For example, the shape of the reversible watch case (1) may be oval or rectangular.
