Description

Fermoir pour bracelet de montre. II existe actuellement des bracelets de montre qui comportent un fermoir constituä par trois 616ments artivul#s les un#s sur les autres ei dont les,deux 616ments extrömes sont destin6s ä Atre reli6s aux extr6mit6s des liens du bracelet. Watch strap clasp. There are currently watch straps that have a clasp made up of three hinged elements one on top of the other, the two end elements of which are intended ä to be connected to the ends of the strap links. .

Ces trois öMments peuvent Atre amenös en position repli#e, les uns sur les autres, ou en position d6ploy6e. Pour oette dernike posi- fion des 616ments du fermoir, le bracelet, muni de sa, mDnire, pr6sente un p#rim6tre suffisant pour donner passage ä la mak de Vusager. Par contre, en position repli6 & des trois #k- ments du fermoir, le bracelet muni de la mon- tre s'aclopte au poignet de Pusager. L'616ment suphieur du fermoir ferm6 prbsente des pa- rois laMrales, de sorte que cet 616ment recou- vre les deux autres qui sont alors pratique- ment invisibles. These three elements can be brought into the folded position, on top of each other, or into the deployed position. For this last posifion of the elements of the clasp, the bracelet, provided with its, mDnire, presents a sufficient perimeter to allow passage ä of the mak of the user. On the other hand, in the folded position of the three #kments of the clasp, the bracelet fitted with the watch is attached to the wrist of the user. The upper element of the closed clasp has side walls, so that this element covers the other two which are then practically invisible.

Etant dünn' cette construetion, il est clair que l'adapia.tion du p6rim#tre du bracelet au pourtour du poiomet de Pusager ne peut s'ei- feetner que, par #d#plaeement du point d'atia- ehe dun seul des liens reliant le fermoir ä la montre. En effet, seul l'616ment du fermoir pr#sentant des parois lat6rales peut Atre pourvu d'une skie, de meyens daecrochage destin6s ä recevoir l'extr#mit6 de l'un des liens. Vautre lien est obligatoirement attac.h6 de maniAre, inamovible ä l'extr6mi-th de l'616ment infhieur du fermoir ferm6. Given this construction, it is clear that the adaptation of the perimeter of the bracelet to the circumference of the user's wrist can only be effected by moving the point of attachment of a single links linking the ä clasp to the watch. Indeed, only the element of the clasp having side walls can be provided with a ski, with hooking means intended ä to receive the end of one of the links. The other link must be attached in a non-removable way ä to the end of the lower element of the closed clasp.

11 s'ensuit que, lorsque 1.e lien doit gtre fix' au moyen daecroe,hage de la skie, le plus #loignö de l'extr#mit# Iibre de l'616ment sup6- rieur du fermoir, celui-ci se trouve Atre dans une position tautä fait dissym6trique par rapport ä la montre. Cette assymätrie du bra- celet est peu esth6tique, d'une, paxt, ei, -d'autre part, rend le bracelet peu agr6able au porter, car la montre, ou le fermoir qui ne sont pas souples, se trouvent Atre sur le c6tä # du poignet. 11 it follows that, when the link must be fixed by means of aecroe, the height of the skie, the farthest from the free end of the upper element of the clasp, it is in a very asymmetrical position with respect to ä the watch. This asymmetry of the bracelet is not very aesthetic, on the one hand, paxt, ei, - on the other hand, makes the bracelet not very pleasant to wear, because the watch, or the clasp which are not flexible, are on the c6tä # of the wrist.

La pr6sente invention a pour objet un èr- moir pour bracelet de montre comportant plu- sieurs 616ments artieu16s les un.#s sur les autres ei dont, les 616ments extrAmee sant destin6s ä C4re reli6s aux extr6mi-lks des liene du 'brace- let. Ce fermoir sedistingue des fermoirs con- r-us par le fait qu'il comporte RTI ID="0001.0275" WI="7" HE="4" LX="1532" LY="1367"> einq 616m-ents, les deux extAmes, munis de paroi-s latärales, kant reli6s ä un 616ment central pardeux 616- ments interm6cliaires ei par le fait que, la lon- gueur de l'616ment central est; plus du double de celle d'un. #kment interm6diaire, de ma- ni#re que ces -derniers puissent Atrer enti & e- ment repli6s sur l'616ment central, Jeux or- ganes de verrouillage kant pr6vu,9 pour main- tenir lesdits 616ments interm6diaires en posi- tion replik sur l'61#ment central. The subject of the present invention is a case for a watch bracelet comprising several 616 elements hinged on top of each other, the extrAme 616 elements being intended ä C4re connected to the extremities of the links of the bracelet. This clasp is distinguished from clasps designed by the fact that it includes RTI ID="0001.0275" WI="7" HE="4" LX="1532" LY="1367"> einq 616m-ents, the two extremities, provided with lateral walls, being connected ä a central element by two intermediate 616-ments and by the fact that, the length of the central element is; more than double that of one. Intermediate element, so that the latter can be completely folded up on the central element, Games of locking members are provided, 9 to maintain the said intermediate elements in the folded position on the central element.

Daus toutes les figures du dessin annex6, les mAmes chiffres de r6f6rence d6signeut des organes ou 616ments ayant möme fonction. In all the figures of the appended drawing, the same reference numerals designate organs or elements having the same function.

Le fermoir comporte einq 616ments 1, 2,3, 4,5 artieule's les uns sur les autres au moyen d'axes d'articulation '6, 7, 8, 9 engagäs dans des gonds form6s par roulage des extr6mit,6s des 616ments. Les 616ments extrAines 1 et5 pr6sentent chaeun une s6rie de moyens d'ae- erochage-#destin6s ä, la fixation en cles' points diff6rents desdits 616ments Je l'une des extr#- miUs de ehaeun des deux liens 10 reliant le Termoir ä la müntre. Ces moyene d'aeprochao"e sont coneti-tu6s chaeun par une paire de per- gages 13 correspondants, pratiqu6s dans des parois latärales 14 que pr6sente chacun des #kments extrAmes 1 et5. Ces paires Je per- gages sent destinks ä recevoir les extr6mi:t#s d'une cheville 11 6mergeant cl'un crochet 12 form6 ä 1'.extr6mit6 d'un lien 10. Ainsi, on peut r6gler la position du point d'attache. de ce lien 10 en plagant. la cheville 11 daus Fune ou Pautre des paires de pergages 13. The clasp comprises five 616 elements 1, 2,3, 4,5 articulated on each other by means of articulation axes '6, 7, 8, 9 engaged in hinges formed by rolling the ends of the elements. The outer elements 1 and 5 each present a series of aero-blasting means-#intended ä, for attachment at different key points of said 616 elements I one of the ends of each of the two links 10 connecting the Termoir ä to the müntre. These approach means are each connected by a pair of corresponding drill holes 13, formed in the side walls 14 which each of the end elements 1 presents. and5. These pairs I drill are intended ä to receive the ends of a peg 11 emerging from a hook 12 formed ä at the end of a link 10. Thus, we can adjust the position of the attachment point of this link 10 by placing the peg 11 in one or the other of the pairs of pergages 13.

L'61#ment central 3 pr6sente une longueui a plus grande que le double -de la longueur d'un 616ment intermädiaire 2, 4, de maniöre que ces deux #kments 2 et 4 puissent Ure repli6s enti#rement sur l'616ment central 3 (fig. 1 et 2). Dans la position fe-rmäe du fer- moir, les 616m#entsaxtr#mes 1 et5 sont ögale- ment -reph6s sur l616ment central 3, les pa- rois latkales 14 venant se placer de part et d'aut-re,des 616ments 2,3 et 4 replks les uns sur les autres. Les 616ments interm6diaires sont maintenus chaeun, en position repli6e sur l'616ment central par un organe de verrouil- lage. Ces deux organes sont cc>ns-Utu6s a'haeun par un bee 15 solidaire de l616inent- central 3 et- coop6rant avee une partie d'un 616ment in- term6dia.ire 2, 4. Dans la fürme d'exkution repr6sent6e ä la fig. 1, les deux bees 15 sont constituös vhacun par une patte emboutie, ve- nue d'une pi6ce,de fabricatien avee l'616ment central 3. Cm bees 15 venant s'appliquer #las- tiquement sur les parties des #kinents 2 et 4 enroukes autour des axes d'articulation 6 et9, retiennent ces deux 616ments en position re- pIke sur l'616m#ent central 3. Les liens 10 exercent chacun, lorsque le bracelet est en po- sition sur le poignet,de Vusager, une traction dirigk suivant les fkühes A et B (fig. 1) sur les 616ments extrAmes 1 et5. On voit sans autre que les aetions de ces liens sont ineapa- bles de provoquer une ouverture intempestive du fermoir, kant donn6 que les bras de leviers sur lesquels elles agissent sont tr6s petits. The central element 3 has a length that is greater than twice the length of an intermediate element 2, 4, so that these two elements 2 and 4 can be folded up entirely. #rly on the central element 3 (fig. 1 and 2). In the closed position of the clasp, the 616 axtreme elements 1 and 5 are also reflected on the central element 3, the side walls 14 coming to be placed on either side, of the 616 elements 2, 3 and 4 folded on top of each other. The intermediate elements are each held in the folded position on the central element by a locking member. These two organs are connected to haeun by a bee 15 attached to the central element 3 and cooperating with part of an intermediate element. 1, 2, 4. In the execution form represented ä in fig. 1, the two arms 15 are each made up of a stamped bracket, made in one piece, manufactured with the central element 3. Cm bees 15 coming to be applied #lasti- cally on the parts of #kinents 2 and 4 wrapped around the axes of articulation 6 and 9, retain these two 616 elements in the repIke position on the central 616 m#ent 3. The links 10 each exert, when the bracelet is in position on the user's wrist, traction directed along arrows A and B (fig. 1) on the extreme elements 1 and 5. It is clear that the actions of these links are unable to cause untimely opening of the clasp, given that the lever arms on which they act are very small.

Dans la variante d'exkution repr6senUe ä, la fig. 2, les bees 15 sont rendus solidaires de l'616ment 3 au moyen de rivets 16 dont un seul est re-pr6sent6. Dans une autre variante, ces bees pourraient Atre rapport6s sur l616ment 3 par soudure. Ces bees coop6rent avec une arke 19 pr6vue dans l'616ment interm6dia.ire pour retenir ces derniers en position repIke sur l'616ment central 3. Ce dernier, pr6sentant une relativement grande longueur, est,de prä- f6rence pourvu de nervures faisant saillies sur sa face interne' c#est-ä-dire-situ6e ä l'int6rieur du fermoir en position fermk. In the alternative embodiment shown ä, in FIG. 2, the beams 15 are secured to the element 3 by means of rivets 16 of which only one is shown. In another variant, these bees could be attached to element 3 by soldering. These bees cooperate with an ark 19 provided in the intermediate element to retain the latter in a repIked position on the central element 3. The latter, presenting a relatively large length, is preferably provided with ribs protruding from its internal face' that is to say, located ä inside the clasp in the closed position .

Le fonctionnement du fermoir d6erit en r66rence au dessin soh6matique annex6 est extr6mement sim-ple. The operation of the clasp described with reference to the attached schematic drawing is extremely simple.

En position ouverte, (fig. 4), il conf6re au bracelet, muni de sa montre, un p6rim#tre suf - fIsant pour donner passage au poignet de Pusager. AprM avoir pass' sa main dan-s le bracelet, il suffit, pour fixer celui-ei sur le poignet, de ramener les 616ments interm6- diaires 2, 4 et les 616ments extrAmes 1, 5 sur l'616ment central 3 et -dexereer une 16g#re pression pour provoquer leur engagement avee les deux bees 15. In the open position (fig. 4), it gives the bracelet, fitted with its watch, a sufficient perimeter to allow passage for the user's wrist. After passing your hand through the bracelet, all you have to do to fix it on your wrist is to bring the intermediate elements 2, 4 and the extreme elements 1, 5 to the wrist. '616 central element 3 and -exert slight pressure to cause them to engage with the two bees 15.

La longueur -du bracelet est r6gl#e en pla- gant chaeune des chevüles 11 dans Pune ou Pautre des paires de pergages correspondants 1.3. On remarque que le point d'aüaclie Je chaque lien 10 kant r6gla.ble, il est possfble de, maintenir le fermoir et la montre -dans des positions sym6triques, c'est-h-dire quune mAme longneur de lien s#pare, de la montre-. chae,une des exträmit6s du fermoir.- Il s'ensuit que l'esth6tique du bracelet reste toujours conservÖe, que le bracelet soit Hgk pour un poignet de grand ou de petit- pourteur. En outre, le fermoir et la montre kant toujours diamkralement oppos6s Fun ä l'autre, le bracelet s'adapte toujours bien au poignet de Fusager tt est agräable au porter. The length -of the bracelet is adjusted by placing each of the pins 11 in one or the other of the pairs of corresponding pergages 1.3. note that the attachment point on each 10 link is adjustable, it is possible to maintain the clasp and the watch -in symmetrical positions, i.e. the same length of separate link, from the watch-. chae, one of the ends of the clasp.- It follows that the aesthetics of the bracelet always remains preserved, whether the bracelet is Hgk for a large or small wrist. Fun ä in addition, the clasp and the watch are always diametrically opposed to each other, the bracelet always adapts well to the user's wrist and is pleasant to wear.

Pour ouvrir le fermoir, il suffit de pineer, entre le pouce et Pindex, Pun des 616ments extrAmes et d'exereer une traction sur celui-ei, ten,dant ä dägager le bee 15 de l'artioulation de l'616ment intermädiaire. To open the clasp, just pinch, between the thumb and the index finger, one of the 616 extreme elements and exert a pull on it, holding ä to disengage the bee 15 of the joint of the intermediate element.
