Description

Description Description

[0001] La presente invention porte sur un dispositif de fixation d'un bracelet amovible ä un boitier de montre, seien le preambule de la revendication 1. The present invention relates to a device for fixing a removable bracelet to a watch case, according to the preamble of claim 1.

[0002] Plus particulierement, II s'agit d'un dispositif dote d'attaches centrales possedant chacune deux bras qui presentent des ouvertures laterales traversantes, partiellement cylindriques, delimitees sur toute leur longueur par une fente longitudinale surmontee de deux ergots pointes vers le centre desdites ouvertures et agences de maniere ä enserrer un tube fendu. Une mollette, de forme exterieure quelconque, egalement munie d'une ouverture laterale interrompue par une fente permettant d'introduire une goupille transversale, attachee aux extremites d'un bracelet, pivote librement autour du tube fendu, sur un angle d'environ 45°, entre une premiere Position dite de verrouillage et une seconde de deverrouillage. Un mecanisme, compose d'une bille de positionnement poussee par un ressort de compression, guide dans un tube chasse dans un boitier de montre, permet de garantir un indexage precis des deux positions stables de verrouillage et de deverrouillage. La configuration des moyens de fixation du bracelet amovible, selon la presente invention, permet un montage reversible du bracelet interchangeable sur le boitier de montre. [0002] More particularly, it is a device with central attachments each having two arms which have through side openings, partially cylindrical, delimited over their entire length by a longitudinal slot surmounted by two lugs pointing towards the center of said openings and arrangements so as to enclose a split tube. A wheel, of any external shape, also provided with a side opening interrupted by a slot allowing the introduction of a transverse pin, attached to the ends of a bracelet, pivots freely around the split tube, over an angle of approximately 45° , between a first so-called locking position and a second unlocking position. A mechanism, consisting of a positioning ball pushed by a compression spring, guided in a tube driven into a watch case, guarantees precise indexing of the two stable locking and unlocking positions. The configuration of the means for fixing the removable bracelet, according to the present invention, allows reversible mounting of the interchangeable bracelet on the watch case.

[0003] On connait un grand nombre de dispositifs de fixation d'un bracelet ä un boitier de montre ä l'aide d'une attache centrale. Dans la plupart des cas, les moyens d'assemblage utilises sont Caches et ne participent pas ä l'elaboration de l'identite esthetique du garde-temps qu'ils equipent. [0003] A large number of devices are known for attaching a bracelet to a watch case using a central attachment. In most cases, the means of assembly used are hidden and do not participate in the development of the aesthetic identity of the timepiece they equip.

[0004] De plus, tres souvent, en fonction de la Position angulaire occupee par le bracelet, sa fixation au boitier de montre n'est pas securisee et les moyens de verrouillage generalement utilises pour resoudre ce Probleme rendent l'interchangeabilite du bracelet difficile voire impossible. [0004] In addition, very often, depending on the angular position occupied by the bracelet, its attachment to the watch case is not secure and the locking means generally used to solve this problem make the interchangeability of the bracelet difficult or even impossible.

[0005] C'est par exemple le cas pour le brevet CH 614 589 qui decrit une boite de montre ä gonds avec dispositif de fixation d'un bracelet aux gonds. [0005] This is for example the case for patent CH 614 589 which describes a hinged watch case with a device for fixing a bracelet to the hinges.

[0006] Les gonds presentent un pergage cylindrique fendu longitudinalement sur toute la longueur du gond, permettant l'introduction de la barre transversale d'une attache destinee ä etre fixee aux extremites du bracelet. Le fond rapporte, qui est mis en place apres les attaches, falt Office de Systeme de verrouillage. [0006] The hinges have a cylindrical pergage split longitudinally over the entire length of the hinge, allowing the introduction of the transverse bar of a fastener intended to be fixed to the ends of the bracelet. The reported bottom, which is put in place after the fasteners, falt Office of Locking System.

[0007] Dans ce dispositif les moyens mis en oeuvre pour fixer le bracelet sont Caches, le verrouillage des barres des attaches dans les gonds par le bord du fond, mis en place apres les attaches, ne permet pas une interchangeabilite simple et rapide du bracelet et, sans Systeme de verrouillage, II existe un secteur angulaire ä l'interieur duquel le bracelet peut se desolidariser de la boite de montre. [0007] In this device, the means used to fix the bracelet are hidden, the locking of the bars of the fasteners in the hinges by the edge of the bottom, put in place after the fasteners, does not allow simple and rapid interchangeability of the bracelet and, without a locking system, there is an angular sector inside which the strap can become detached from the watch case.

[0008] Aussi le but de la presente invention est de proposer un dispositif de fixation d'un bracelet amovible ä un boitier de montre palliant les inconvenients de verrouillage et d'interchangeabilite du bracelet, enumeres supra, tout en proposant un mecanisme spectaculaire dont tout ou partie des moyens de fixation du bracelet au boitier de montre participent ä l'elaboration de l'identite esthetique de la montre bracelet. [0008] Also the object of the present invention is to provide a device for fixing a removable bracelet to a watch case overcoming the disadvantages of locking and interchangeability of the bracelet, listed above, while proposing a spectacular mechanism whose whole or part of the means for attaching the bracelet to the watch case participate in the development of the aesthetic identity of the wristwatch.

[0009] Cet objectif est atteint gräce aux moyens definis dans la revendication 1, des moyens particuliers et preferentiels pour realiser l'invention ä bon compte sont definis dans les revendications dependantes, [0009] This object is achieved by the means defined in claim 1, particular and preferential means for carrying out the invention inexpensively are defined in the dependent claims,

[0010] Une forme de realisation du dispositif de fixation d'un bracelet amovible ä un boitier de montre va maintenant etre decrite en detail, ä titre d'exemple nom limitatif, ä l'appui des dessins annexes (ä echelles non uniforme, dans lesquels. [0010] An embodiment of the device for attaching a removable bracelet to a watch case will now be described in detail, by way of example, a limiting name, with the support of the appended drawings (non-uniform scales, in which.

La figure 1 est une vue en perspective d'un boitier de montre muni du dispositif de fixation du bracelet amovible avec une coupe locale au niveau d'une des vis d'indexage du bracelet, Figure 1 is a perspective view of a watch case provided with the device for fixing the removable bracelet with a local section at the level of one of the indexing screws of the bracelet,

La figure 2 est une vue en perspective, partiellement eclatee, d'un boitier de montre muni du dispositif de fixation du bracelet amovible, Figure 2 is a perspective view, partially exploded, of a watch case provided with the device for fixing the removable bracelet,

La figure 3 est une vue en coupe, selon un plan 6H - 12H, d'un boitier de montre muni du dispositif de fixation du bracelet amovible, en position verrouillee, Figure 3 is a sectional view, along a 6H - 12H plane, of a watch case fitted with the device for fixing the removable bracelet, in the locked position,

La figure 4 est une vue en coupe, selon un plan 6H - 12H, d'un boitier de montre muni du dispositif de fixation du bracelet amovible, en position deverrouillee, FIG. 4 is a cross-sectional view, along a 6 o'clock - 12 o'clock plane, of a watch case fitted with the device for fixing the removable bracelet, in the unlocked position,

[0011] Les figures 1 et 2 representent une vue en perspective d'un boitier de montre 1, equipe de deux attaches centrales 2, solidaires d'une carrure 3 dans laquelle sont chasses classiquement un fond 4 et une glace 5. Des vis 6, orientees selon des axes de pergage ZI -ZI 'et Z2-Z2,' maintiennent un bracelet 7 sur une goupille transversale 8 par l'intermediaires detaraudages 10 situes de part et d'autre de deux meplatsl 1, paralleles entre eux. Les axes de pergage Z^Z/et des taraudages 10 sont de preference perpendiculaires aux faces des meplats 11 et coupent un axe de pivotement X^X/ou X2-X2' qui coincide avec Taxe de la goupille transversale 8. On pourrait egalement Iler le bracelet 7 ä la goupille transversale8 en prolongeant les deux parties cylindriques 9, situees de part et d'autre des deux meplats 11, par deux fines languettes, paralleles aux axes Z1 -ZI 'et Z2-Z2', inserees ä l'interieur des extremites du bracelet 7. Ce second mode de fixation dubracelet 7 sur la goupille transversale 8 semble particulierement adapte pour la realisation de bracelets reversibles. [0011] Figures 1 and 2 represent a perspective view of a watch case 1, equipped with two central fasteners 2, integral with a middle part 3 in which are conventionally recessed a bottom 4 and a crystal 5. Screws 6 , oriented along pergage axes ZI -ZI 'and Z2-Z2,' maintain a bracelet 7 on a transverse pin 8 by the intermediaries of threads 10 located on either side of two flatsl 1, parallel to each other. The pergage axes Z^Z/ and of the tappings 10 are preferably perpendicular to the faces of the flats 11 and intersect a pivot axis X^X/or X2-X2' which coincides with the axis of the transverse pin 8. It could also be Iler the bracelet 7 to the transverse pin 8 by extending the two cylindrical parts 9, located on either side of the two flats 11, by two thin tongues, parallel to the axes Z1 -ZI 'and Z2-Z2', inserted inside ends of the bracelet 7. This second method of fixing dubracelet 7 on the transverse pin 8 seems particularly suitable for making reversible bracelets.

[0012] L'eclatement partiel de la figure 2 montre egalement que les attaches centrales 2 possedent chacune deux bras 17, paralleles entre eux et separes par une ouverture centrale delimitee par des faces internes 22. Une molette 12 vient se leger entre les deux faces internes 22 qui limitent son deplacement le long de Taxe de pivotement X^X/ou X2-X2'. La molette The partial breakdown of Figure 2 also shows that the central fasteners 2 each have two arms 17, parallel to each other and separated by a central opening delimited by internal faces 22. A wheel 12 comes lightly between the two faces internal 22 which limit its movement along pivot axis X^X/or X2-X2'. The wheel

12 tourne librement autour d'un tube fendu 13 porteur d'un diametre exterieur et interieur, respectivement references, 14 et 15 et de deux faces 16 formant entre elles un angle d'environ 110°. L'indexage de la molette 12, permettant de definir avec precision les deux positions stables de verrouillage et de deverrouillage du mecanisme, sera decrit plus loin. Des ouvertures laterales 18 sont amenagees dans les bras 17 des attaches centrales 2. Elles sont composees d'une partie cylindrique 19, coaxiale ä Taxe de pivotement X^X/ ou X2-X2', prolongee par des faces 21, formant entre elles un anglede 110°, surmontees par des ergots 20 pointes vers le centre desdites ouvertures laterales 18. Les faces 16 du tube fendu 12 rotates freely around a split tube 13 carrying an outer and inner diameter, respectively references, 14 and 15 and two faces 16 forming between them an angle of approximately 110°. The indexing of the wheel 12, making it possible to define with precision the two stable positions of locking and unlocking of the mechanism, will be described later. Lateral openings 18 are arranged in the arms 17 of the central attachments 2. They are composed of a cylindrical part 19, coaxial with the axis of pivoting X^X/ or X2-X2', extended by faces 21, forming between them a angle of 110°, surmounted by lugs 20 pointing towards the center of said lateral openings 18. The faces 16 of the split tube

13 cooperent parfaitement avec les faces 21 des ouvertures laterales 18. 13 cooperate perfectly with the faces 21 of the side openings 18.

[0013] A l'instar des bras 17 des attaches centrales 2, la molette 12 possede egalement une ouverture laterale 23, formee d'une partie cylindrique 24, coaxiale ä Taxe de pivotement X1-X1' ou X2-X2', dont une des extremites est prolongee parune face 26 surmontee par un ergot 25 pointe vers le centre de l'ouverture laterale 23. Le pourtour de la molette porte egalement un point de couleur 27, de preference rouge, qui est visible lorsque le dispositif de fixation du bracelet 7 est en Position deverrouillee et invisible lorsque le dispositif de fixation du bracelet 7 est en position verrouillee. [0013] Like the arms 17 of the central attachments 2, the wheel 12 also has a side opening 23, formed by a cylindrical part 24, coaxial with the axis of pivoting X1-X1' or X2-X2', one of which of the ends is extended by a face 26 surmounted by a lug 25 pointing towards the center of the side opening 23. The periphery of the wheel also bears a colored dot 27, preferably red, which is visible when the strap fastening device 7 is in the unlocked and invisible position when the wristband fixing device 7 is in the locked position.

[0014] Sur la figure 3 on voit un tube 28, chasse dans la carrure 3. Un ressort de compression 29 coulisse ä l'interieur du tube 28 et pousse une bille d'indexage 30 qui vient se loger dans une encoche 31, de preference spherique ou cylindrique, disposee sur une face interieure 34 d'une rainure cylindrique 33 amenagee sur une partie du pourtour de la molette In Figure 3 we see a tube 28, flush in the caseband 3. A compression spring 29 slides inside the tube 28 and pushes an indexing ball 30 which is housed in a notch 31, preferably spherical or cylindrical, disposed on an inner face 34 of a cylindrical groove 33 arranged on part of the circumference of the wheel

12 couvrant un angle a d'environ 45°. L'engagement de la bille 30 dans l'encoche 31 defini avec precision la position stable de verrouillage du mecanisme. Dans cette position l'ergot 25 de la molette 12 se situe environ ä egale distance des deux ergots 20 des bras 17 de l'attache centrale 2 et sa face 26 est separee d'une des face 16, du tube fendu 13, par un angle a d'environ 45°. 12 covering an angle a of approximately 45°. The engagement of the ball 30 in the notch 31 precisely defines the stable locking position of the mechanism. In this position, the lug 25 of the wheel 12 is approximately equidistant from the two lugs 20 of the arms 17 of the central attachment 2 and its face 26 is separated from one of the faces 16 of the split tube 13 by a angle a of approximately 45°.

[0015] Pour l'attache situee ä 6H les deux meplats 11 sont Orientes parallelement ä faxe du bracelet 7 qui forme un angle ß, d'environ 30°, avec faxe vertical Y^Y/. Dans cette configuration l'orientation de la fente de l'attache centrale 2 et celle de la molette 12 ne coincident pas. De plus un des deux ergots 20 ainsi qu'une partie du diametre interieur 15 du tube fendu 13 appuient sur la partie cylindrique 9 de la goupille transversale 8 et la maintiennent parfaitement sur son axe de pivotement XvX/. [0015] For the attachment located at 6 o'clock, the two flats 11 are oriented parallel to the axis of the strap 7 which forms an angle β, of approximately 30°, with the vertical axis Y^Y/. In this configuration, the orientation of the slot of the central attachment 2 and that of the knob 12 do not coincide. In addition, one of the two lugs 20 and part of the inner diameter 15 of the split tube 13 bear on the cylindrical part 9 of the transverse pin 8 and hold it perfectly on its pivot axis XvX/.

[0016] Pour l'attache situee ä 12H les deux meplats 11 sont Orientes parallelement ä Taxe du bracelet 7 qui forme un angle y, d'environ 40°, avec Taxe vertical Y2-Y2'. Dans cette configuration l'orientation de la fente de l'attache centrale 2 et cellede la molette 12 ne coincident pas. De plus l'ergot 25 ainsi qu'une partie du diametre interieur 15 du tube fendu 13 appuient sur la partie cylindrique 9 de la goupille transversale 8 et la maintiennent parfaitement sur son axe de pivotement X2-X2'. [0016] For the attachment located at 12 o'clock, the two flats 11 are oriented parallel to the axis of the bracelet 7 which forms an angle y, of approximately 40°, with the vertical axis Y2-Y2'. In this configuration, the orientation of the slot of the central attachment 2 and that of the knob 12 do not coincide. In addition, the lug 25 and part of the inner diameter 15 of the split tube 13 bear on the cylindrical part 9 of the transverse pin 8 and hold it perfectly on its pivot axis X2-X2'.

[0017] A ce stade de la description, il est utile de preciser que pour optimiser la qualite de maintien de la goupille transversale 8 sur son axe de pivotement X1-X1' ou X2-X2', il est preferable que la longueur des ergots 20 des attaches centrales2, ainsi que de l'ergot 25 de la molette 12, soit sensiblement egale ä l'epaisseur de la paroi du tube fendu 13. [0017] At this stage of the description, it is useful to specify that to optimize the quality of maintenance of the transverse pin 8 on its pivot axis X1-X1 'or X2-X2', it is preferable that the length of the lugs 20 of the central fasteners 2, as well as the lug 25 of the knob 12, is substantially equal to the thickness of the wall of the split tube 13.

[0018] Des lors, on peut affirmer que l'agencement des deux ergots 20 de l'attache centrale 2, combine avec celui de l'ergot 25 de la molette 12, assure, pour toutes les positions angulaires occupees par le bracelet, un maintien axial optimal de la goupille transversale 8, lorsque la molette est en position verrouillee. [0018] Therefore, it can be said that the arrangement of the two lugs 20 of the central attachment 2, combined with that of the lug 25 of the knob 12, ensures, for all the angular positions occupied by the bracelet, a optimal axial retention of the cross pin 8, when the wheel is in the locked position.

[0019] La figure 4 montre que de la bille 30 vient se loger dans l'encoche 32 et defini avec precision la position stable de deverrouillage du mecanisme. La position de l'ergot 25 de la molette 12 se confond avec celle de Tun des deux ergots 20 de l'attache centrale 2 et la face 26 de l'ergot 25 se superpose avec une des faces 16, du tube fendu 13. Figure 4 shows that the ball 30 is housed in the notch 32 and precisely defined the stable position of the mechanism unlocking. The position of the lug 25 of the knob 12 merges with that of Tun of the two lugs 20 of the central attachment 2 and the face 26 of the lug 25 overlaps with one of the faces 16 of the split tube 13.

[0020] Pour l'attache situee ä 6H les deux meplats 11 sont Orientes parallelement ä Taxe du bracelet 7 qui forme un angle ß, d'environ 30°, avec Taxe vertical Y1-Y1'. Dans cette configuration l'orientation de la fente de l'attache centrale 2 etcelle de la molette 12 coincident, mais un des deux ergots 20 ainsi qu'une partie du diametre interieur 15 du tube fendu [0020] For the attachment located at 6 o'clock, the two flats 11 are oriented parallel to the axis of the bracelet 7 which forms an angle β, of approximately 30°, with the vertical axis Y1-Y1'. In this configuration the orientation of the slot of the central attachment 2 and that of the wheel 12 coincide, but one of the two lugs 20 as well as a part of the internal diameter 15 of the split tube

13 appuient sur la partie cylindrique 9 de la goupille transversale 8 et la maintiennent sur son axe de pivotement X^X/. 13 press on the cylindrical part 9 of the transverse pin 8 and hold it on its pivot axis X^X/.

[0021] Pour l'attache situee ä 12H les deux meplats 11 sont Orientes parallelement ä Taxe du bracelet 7 qui forme un angle y, d'environ 40°, avec Taxe vertical Y2-Y2'. Dans cette configuration l'orientation de la fente de l'attache centrale 2 et cellede la molette 12 coincident et ni l'ergot 25 de la molette 12 ni Tun des deux ergots 20 de l'attache centrale 2 n'appuient sur la partie cylindrique 9 de la goupille transversale 8. Comme l'epaisseur delimitee par les deux meplats 11 de la goupille transversale 8 est legerement interieure ä la largeur des fentes des attaches centrales 2 ainsi qu'ä celle de la molette 12 on peut engager ou retirer librement le bracelet 7 en le faisant coulisser le long de son axe. [0021] For the attachment located at 12 o'clock, the two flats 11 are oriented parallel to the axis of the bracelet 7 which forms an angle y, of approximately 40°, with the vertical axis Y2-Y2'. In this configuration, the orientation of the slot of the central attachment 2 and that of the wheel 12 coincide and neither the lug 25 of the wheel 12 nor one of the two lugs 20 of the central attachment 2 press on the cylindrical part 9 of the transverse pin 8. As the thickness delimited by the two flats 11 of the transverse pin 8 is slightly inside the width of the slots of the central fasteners 2 as well as that of the wheel 12, it is possible to freely engage or withdraw the bracelet 7 by sliding it along its axis.

[0022] A La lecture de la description qui precede, on se rend compte que l'epaisseur du bracelet ainsi que la matiere utilisee pour sa realisation n'ont aucune influence sur le fonctionnement du dispositif de fixation selon la presente invention. Cette caracteristique offre une grande liberte de creation au niveau de l'esthetique du bracelet et du dispositif de fixation. On reading the above description, we realize that the thickness of the bracelet and the material used for its realization have no influence on the operation of the fastening device according to the present invention. This characteristic offers great creative freedom in terms of the aesthetics of the bracelet and the fastening device.
