Abstract

The invention concerns a system for removably securing a bracelet (12) to a watch case (10), comprising a sliding assembly consisting of two parts provided one (14) with a slide (24, 26) and the other (16) with a slot (28), and a lock comprising a elastic interlocking member (38, 40) and a positioning member (24d, 24e, 26d). One of the parts (14) of the assembly and one of the members (24d, 24e, 26d) of the lock are integral with the case (10), the others (16; 38, 40) with the bracelet (12). The slide (24, 26) can be moved in the slot (28) along a so-called sliding direction. The invention is characterised in that the elastic interlocking member (38, 40) exerts a force, pressing a contact surface against the positioning member (24d, 24e, 26d), oriented along a direction forming a different angle from 0 to 90 DEG with the sliding direction.

Description

La présente invention se rapporte aux systèmes d'attache amovible d'un bracelet à une boíte de montre. Elle concerne plus particulièrement les systèmes comportant un ensemble coulissant, formé de deux parties munies l'une d'un coulisseau et l'autre d'une coulisse, et un verrou comportant un organe à enclenchement élastique et un organe de positionnement. Les deux parties sont rendues solidaires l'une de l'autre par engagement du coulisseau dans la coulisse et maintenues au moyen du verrou. L'une des parties et l'un des organes sont solidaires de la boíte, les autres du bracelet. De la sorte, la boíte et le bracelet peuvent être déplacé l'un en regard de l'autre, le coulisseau glissant dans la coulisse, dans une direction dite de coulissement, tant que le verrou n'est pas enclenché.The present invention relates to removable attachment systems of a bracelet to a watch case. It relates more particularly to systems comprising a sliding assembly, formed of two parts provided one of a slide and the other of a slide, and a lock comprising a elastic locking member and a positioning member. Both parts are made integral with each other by engagement of the slide in the slide and held by the lock. One of the parties and one of organs are integral with the box, the others with the bracelet. In this way, the box and the bracelet can be moved opposite each other, the sliding slide in the slide, in a direction called sliding, as long as the latch is not engaged.

Une montre, utilisant un tel système, est décrite dans le document CH-170503. La partie solidaire du bracelet est munie d'une coulisse alors que l'autre, solidaire de la boíte, forme un coulisseau agencé de manière à pouvoir être engagé dans la coulisse. Le verrou, dans lequel l'organe élastique est constitué d'une lame de ressort et l'organe de positionnement d'une gorge dont la paroi est perpendiculaire à la direction de coulissement, empêche le désenclenchement du système. Plus précisément, la lame est fixée à la boíte et la gorge est pratiquée dans le bracelet. Le tout est agencé de manière à ce que les parties de l'ensemble ne puissent être séparées l'une de l'autre qu'en soulevant le ressort au moyen d'un ongle ou de tout autre outil. En d'autres termes, l'utilisateur doit appliquer une première force, perpendiculaire à la direction de coulissement, pour soulever le ressort, avant d'appliquer une deuxième force dans la direction du coulissement, pour dégager le coulisseau de la coulisse. A watch, using such a system, is described in document CH-170503. The integral part of the bracelet is provided with a slide while the other, integral with the box, forms a slide arranged so that it can be backstage. The lock, in which the elastic member is made of a spring leaf and the positioning member of a groove whose wall is perpendicular to the sliding direction, prevents the system shutdown. More specifically, the blade is fixed to the box and the throat is made in the bracelet. Everything is arranged so that the parts of the whole can only be separated from each other by lifting the spring with a fingernail or other tool. In others terms, the user must apply a first force, perpendicular to the sliding direction, to lift the spring, before applying a second force in the direction of sliding, to release the slide backstage.

Une telle solution permet d'assurer un blocage du bracelet sur la boíte et d'éviter toute séparation malencontreuse des parties de l'ensemble. La manipulation qu'elle nécessite est, toutefois, délicate, avec risque de se casser un ongle.Such a solution ensures a blocking of the bracelet on the box and to avoid any accidental separation of the parts of the whole. The handling it requires is, however, delicate, with the risk of breaking a nail.

De plus, pour séparer le bracelet de la boíte, l'utilisateur doit obligatoirement enlever sa montre du poignet. Le système ne peut, en conséquence, être utilisé comme fermoir de bracelet.In addition, to separate the bracelet from the box, the user must take off your watch from your wrist. The system cannot therefore be used as a bracelet clasp.

Or, la pratique a montré qu'un blocage de l'ensemble était inutile et que, par des moyens très simples, il était possible de réaliser un système d'attache du bracelet à la boíte facile à enlever et qui, pourtant, ne pose pas de problème de désengagement intempestif du coulisseau. Ce but est atteint grâce au fait que l'organe à enclenchement élastique est agencé de manière à exercer une force, appliquant une surface de contact en appui contre l'organe de positionnement, orientée selon une direction faisant un angle non nul et non perpendiculaire avec la direction de coulissement.However, practice has shown that blocking the assembly was unnecessary and that, by very simple means, it was possible to achieve a system of attachment of the bracelet in the box easy to remove and which, however, does not pose a problem of inadvertent disengagement of the slide. This goal is achieved thanks to the fact that the elastic latching member is arranged so as to exert a force, applying a contact surface in abutment against the positioning member, oriented in a direction making a non-zero and non-perpendicular angle with the sliding direction.

Ainsi, bien que le verrou soit de type à engagement élastique, c'est-à-dire du type dans lequel les organes peuvent être déplacés l'un par rapport à l'autre en appliquant uniquement une force orientée dans la direction de coulissement, les deux organes restent solidaires l'un de l'autre pratiquement sans risque de désengagement.Thus, although the lock is of the elastic engagement type, that is to say of the type in which organs can be moved relative to each other by applying only a force directed in the sliding direction, the two organs remain integral with each other practically without risk of disengagement.

Dans un mode de réalisation particulièrement simple, l'organe à enclenchement élastique comporte un doigt, engagé et monté coulissant dans un trou, et un ressort coopérant avec le doigt. L'organe de positionnement est constitué d'une creusure. L'un des organes est associé à la boíte, l'autre au bracelet.In a particularly simple embodiment, the latching member elastic comprises a finger, engaged and slidably mounted in a hole, and a spring cooperating with the finger. The positioning device consists of a hollow. One of the organs is associated with the box, the other with the bracelet.

Par des moyens peu coûteux, il est possible d'améliorer la sécurité de la fixation. A cet effet, le verrou comporte, au moins, deux doigts alignés selon la direction de coulissement et solidaires de l'une des parties, et au moins deux creusures également alignées selon cette direction et pratiquées dans l'autre partie, la distance comprise entre les creusures étant égale à celle comprise entre les doigts, de manière à ce que, en position verrouillée, les deux doigts soient engagés chacun dans une creusure et en ce que, dans une position intermédiaire par laquelle doivent passer les deux parties pour les déverrouiller, l'un des deux doigts est engagé dans la creusure coopérant avec l'autre doigt en position verrouillée.By inexpensive means, it is possible to improve the security of the fixation. For this purpose, the lock comprises, at least, two fingers aligned according to the sliding direction and integral with one of the parts, and at least two recesses also aligned in this direction and made in the other part, the distance between the recesses being equal to that included between the fingers, so that, in the locked position, the two fingers are each engaged in a hollow and in that in a position intermediary through which the two parts must pass to unlock them, one of the two fingers is engaged in the recess cooperating with the other finger in locked position.

Dans une variante encore plus performante, en position verrouillée, trois doigts sont engagés dans trois creusures.In an even more efficient variant, in the locked position, three fingers are engaged in three excavations.

Une solution particulièrement avantageuse consiste à utiliser un enclenchement de type à baïonnette, c'est-à-dire avec une coulisse formée de deux parois parallèles définissant une gorge disposée axialement, et de saillies solidaires des parois et recouvrant partiellement la gorge, sur deux premières portions de sa longueur et laissant découvertes deux secondes portions et un coulisseau formé de deux têtes portées chacune par un tigeron, dont la dimension axiale de la tête est légèrement inférieure à la longueur des secondes portions, dont les tigerons présentent une longueur légèrement supérieure à l'épaisseur des saillies. En outre, les têtes ont une hauteur légèrement inférieure à la profondeur de la gorge et une largeur légèrement inférieure à la largeur de la gorge, mais supérieure à la distance comprise entre les saillies.A particularly advantageous solution consists in using an interlocking bayonet type, i.e. with a slide formed by two walls parallel defining an axially arranged groove, and integral projections walls and partially covering the throat, on the first two portions of its length and leaving uncovered two second portions and a slide formed of two heads each carried by a tigeron, whose axial dimension of the head is slightly less than the length of the second portions, the tigerons have a length slightly greater than the thickness of protrusions. In addition, the heads have a height slightly less than the throat depth and a width slightly less than the width of the groove, but greater than the distance between the projections.

La présente invention concerne également une montre bracelet. Dans de telles montres, le bracelet joue un rôle esthétique important. En donnant la possibilité au porteur de le remplacer par un autre, on lui offre la possibilité de changer sa montre d'aspect.The present invention also relates to a wristwatch. In such watches, the bracelet plays an important aesthetic role. By giving the possibility bearer to replace it with another, he is offered the opportunity to change his appearance watch.

A cet effet, la montre selon l'invention est munie d'une boíte et d'un bracelet, reliés l'un à l'autre au moyen de deux systèmes tels que définis plus haut. Dans cette montre, le bracelet est formé d'un seul brin ayant deux extrémités, chacune munie d'une partie de l'un des ensembles coulissants et d'un des organes du verrou et la boíte porte les parties et les organes complémentaire, les directions de coulissement étant disposées dans un même plan.To this end, the watch according to the invention is provided with a box and a bracelet, linked to each other by means of two systems as defined above. In this watch, the bracelet is formed of a single strand having two ends, each fitted with part of one of the sliding assemblies and one of organs of the lock and the box carries the parts and the complementary organs, the sliding directions being arranged in the same plane.

Afin d'augmenter la diversité des aspects que la montre est susceptible de présenter, il est avantageux que le bracelet puisse être utiliser sur ces deux faces. Pour ce faire, le système selon l'invention comporte des ensembles et des verrous qui présentent une symétrie par rapport au plan dans lequel s'inscrivent les directions de coulissement.In order to increase the diversity of aspects that the watch is likely to present, it is advantageous that the bracelet can be used on these two faces. To do this, the system according to the invention comprises assemblies and locks which are symmetrical with respect to the plane in which they are inscribed sliding directions.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel:

  • La figure 1 est une vue d'ensemble d'une montre équipée d'un système selon l'invention;
  • La figure 2 montre le système de la figure 1 coupé selon la ligne II-II, agrandi; et
    • Other advantages and characteristics of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  • Figure 1 is an overview of a watch equipped with a system according to the invention;
  • Figure 2 shows the system of Figure 1 cut along line II-II, enlarged; and

    • La figure 3 illustre différents assemblages réalisés au moyen du système selon l'invention.Figure 3 illustrates different assemblies made using the system according to the invention.

    La montre représentée sur la figure 1 comporte une boíte 10 et un bracelet 12 destinés à être assemblés l'un à l'autre. Ils sont munis, à cet effet, de deux ensembles coulissants formés chacun d'une première partie 14 et d'une seconde partie 16, respectivement solidaires, par paires de la boíte 10 et du bracelet 12.The watch shown in Figure 1 has a box 10 and a strap 12 intended to be assembled together. They are provided, for this purpose, with two sliding assemblies each formed by a first part 14 and a second part 16, respectively secured, in pairs of the box 10 and the bracelet 12.

    La boíte 10 est de forme générale rectangulaire. Elle est munie, sur un côté, d'une tige de mise à l'heure 18 et, sur l'une de ses faces, d'une glace 20 au travers de laquelle il est possible de voir des aiguilles 22, qui assurent l'affichage de l'heure. The box 10 is of generally rectangular shape. It has, on one side, a time setting rod 18 and, on one of its faces, a crystal 20 at through which it is possible to see needles 22, which provide time display.

    Les parties 14 sont disposées sur deux des côtés de la boíte, la partie 14a se trouvant du côté correspondant à midi sur le cadran et la partie 14b à 6 heures, alors que la tige 18 se trouve du côté correspondant à 3 heures.The parts 14 are arranged on two sides of the box, the part 14a is finding on the side corresponding to noon on the dial and part 14b at 6 o'clock, while the rod 18 is on the side corresponding to 3 hours.

    Chaque partie 14 comporte deux coulisseaux 24 et 26 de section en T, avec un corps portant la référence a et deux bras b et c (figure 2). Les corps 24a et 26a sont solidaires de la boíte 10 et les bras 24b, 24c, 26b et 26c s'étendent parallèlement aux côtés de la boíte dont ils sont adjacents. Les coulisseaux 24 et 26 comportent respectivement deux rainures portant les références d et e, et une rainure d, qui s'étendent sur la largeur des deux bras b et c.Each part 14 comprises two slides 24 and 26 of T-shaped section, with a body bearing the reference a and two arms b and c (Figure 2). The bodies 24a and 26a are integral with the box 10 and the arms 24b, 24c, 26b and 26c extend parallel to the sides of the box of which they are adjacent. The slides 24 and 26 respectively have two grooves bearing the references d and e , and a groove d , which extend over the width of the two arms b and c .

    Les parties 16 comportent chacune une coulisse 28 de forme complémentaire aux coulisseaux 24 et 26, munies de deux parois parallèles 30a et 30b définissant une gorge 32 orientée dans la direction de coulissement, et distantes l'une de l'autre d'une valeur L légèrement supérieure à l'écartement l des deux bras. Des saillies 34a et 34b, solidaires des parois 30a et 30b recouvrent partiellement la gorge 32, laissant découvertes deux portions qui définissent des ouvertures d'engagement 36. La distance E entre les saillies 34a et 34b est légèrement supérieure à la largeur e du corps des coulisseaux 24 et 26.The parts 16 each include a slide 28 of shape complementary to the slides 24 and 26, provided with two parallel walls 30a and 30b defining a groove 32 oriented in the sliding direction, and spaced from each other by a value L slightly greater than the spacing l of the two arms. Projections 34a and 34b, integral with the walls 30a and 30b partially cover the groove 32, leaving uncovered two portions which define engagement openings 36. The distance E between the projections 34a and 34b is slightly greater than the width e of the body of the slides 24 and 26.

    Le fond de la gorge 32 est percé de trois trous filetés, dont deux 37a et 37b sont visibles sur la figure 1 et le troisième 37c sur la figure 2, et dans chacun desquels est fixé, par vissage, un organe à enclenchement élastique comportant un corps 38 de forme générale cylindrique, à l'intérieur duquel est logé une bille 40 et un ressort à boudin non représenté au dessin. Le tout est agencé de manière à ce que la bille 40 soit maintenue dans le corps et dépasse du fond de la gorge 32.The bottom of the groove 32 is pierced with three threaded holes, two of which 37a and 37b are visible in Figure 1 and the third 37c in Figure 2, and in each which is fixed, by screwing, an elastic latching member comprising a body 38 of generally cylindrical shape, inside which is housed a ball 40 and a coil spring not shown in the drawing. The whole is arranged so that the ball 40 is held in the body and protrudes from the bottom of throat 32.

    Les trous 37 sont disposés de manière à ce que les billes 40 soient chacune engagée dans l'une des rainures 24d, 24e et 26d, et en appui contre leurs parois, exerçant des forces orientées selon des directions faisant, avec la direction de coulissement, un angle différent de 0 et 90°. Il est, de la sorte, possible de garantir un positionnement tout en permettant un désenclenchement sans devoir retirer une pièce du verrou.The holes 37 are arranged so that the balls 40 are each engaged in one of the grooves 24d, 24e and 26d, and pressing against their walls, exerting forces oriented in directions doing, with the direction of sliding, an angle different from 0 and 90 °. It is thus possible to guarantee positioning while enabling disengagement without having to remove a part from the lock.

    En d'autres termes, les billes 40 jouent un rôle de doigt élastique engagé dans l'une des rainures, qui assure une fonction d'organe de positionnement.In other words, the balls 40 play the role of an elastic finger engaged in one of the grooves, which provides a positioning member function.

    La gorge 32 est obturée à chacune de ses extrémités, de manière à former des butées, non représentée sur le dessin, pour éviter de le surcharger.The groove 32 is closed at each of its ends, so as to form stops, not shown in the drawing, to avoid overloading it.

    Il y a lieu de relever, comme on peut le voir sur la figure 2, que les parties 14 et 16 présentent un plan de symétrie P qui passe par le milieu des corps 24a et 26a, et par les axes des trous 37.It should be noted, as can be seen in Figure 2, that parts 14 and 16 have a plane of symmetry P which passes through the middle of the bodies 24a and 26a, and by the axes of the holes 37.

    Pour assembler deux parties 14 et 16, il suffit de placer la partie 16 de façon que les coulisseaux 26 et 28 se trouvent en regard des ouvertures de dégagement 36,comme indiqué sur la figure 1, puis qu'ils soient introduits dans la gorge 32. La partie 16 est ensuite déplacée selon la direction de coulissement, jusqu'à ce que les billes 40a et 40b s'engagent dans les rainures 24d et 24e, et la bille 40c dans la rainure 26d, le coulisseau 28 atteignant alors la butée. Les ressorts exercent sur les billes 40 une force les maintenant en appui contre les parois des rainures 24d, 24e et 26d, par des surfaces de contact. L'ensemble est agencé de manière que chaque bille exerce, sur ces parois, une force résultante orientée selon une direction qui fait un angle différent de 0 et de 90° par rapport à la direction de coulissement.To assemble two parts 14 and 16, simply place part 16 so that the slides 26 and 28 are located opposite the openings of clearance 36, as shown in figure 1, then they are introduced into the groove 32. The part 16 is then moved in the direction of sliding, until the balls 40a and 40b engage in the grooves 24d and 24e, and the ball 40c in the groove 26d, the slide 28 then reaching stop. The springs exert on the balls 40 a force keeping them in support against the walls of the grooves 24d, 24e and 26d, by contact surfaces. The assembly is arranged so that each ball exerts, on these walls, a resulting force oriented in a direction that makes an angle different from 0 and 90 ° to the sliding direction.

    De la sorte, il est nécessaire et suffisant d'appliquer une force adéquate, orientée selon une direction sensiblement parallèle à la direction de coulissement. Comme la surface de contact de l'organe élastique avec l'organe de positionnement n'est pas perpendiculaire à la direction de coulissement, il n'y a pas de blocage.In this way, it is necessary and sufficient to apply an adequate force, oriented in a direction substantially parallel to the direction of sliding. As the contact surface of the elastic organ with the organ position is not perpendicular to the sliding direction, it there is no blockage.

    Les essais effectués ont montré que, de manière surprenante, un tel système permet de maintenir solidement l'ensemble formé des parties 14 et 16, pratiquement sans risque de décrochement. De plus, si de manière malencontreuse, une force provoquait un léger déplacement des coulisseaux 24 et 26 dans la coulisse 28, il serait interrompu au moment ou la bille 40a, sortie de la première rainure 24d passe dans la rainure 24e. Le bracelet peut, ainsi, être facilement remis en place, avant que la montre ne se décroche.Tests have shown that, surprisingly, such a system allows the assembly formed by parts 14 and 16 to be held securely, practically without risk of dropout. In addition, if so unfortunate, a force caused a slight displacement of the slides 24 and 26 in the slide 28, it would be interrupted when the ball 40a, out of the first groove 24d passes into the groove 24e. The bracelet can, as well, be easily replaced before the watch comes off.

    Un tel système permet, non seulement, de réaliser un assemblage simple d'un bracelet à une boíte de montre, mais encore d'apporter des possibilités de modifier l'aspect de la montre, comme on peut le voir sur la figure 3.Such a system not only makes it possible to carry out a simple assembly of a bracelet to a watch case, but still to bring possibilities of change the appearance of the watch, as you can see in Figure 3.

    Plus précisément, la figure 3a représente une montre dans laquelle le bracelet 12 et la boíte 10 sont assemblés, de manière à ce que l'affichage de l'heure soit visible.More specifically, FIG. 3a represents a watch in which the bracelet 12 and the box 10 are assembled, so that the time display is visible.

    Comme le montre la figure 3b, il est aussi possible de masquer l'affichage, en laissant apparaítre le fond de la boíte 10, qui peut, par exemple, être gravé. Pour ce faire, il suffit de décrocher le système par désenclenchement des parties 14 et 16, et de tourner la boíte de 180° autour de l'axe de la tige de mise à l'heure 18. En procédant ainsi, on transforme la montre en bijou, avec, toutefois, le même aspect du bracelet. On relèvera qu'une telle solution n'est applicable que dans la mesure où les organes 14 et 16 présentent un plan de symétrie, passant par les deux axes de coulissement.As shown in Figure 3b, it is also possible to hide the display, by revealing the bottom of the box 10, which can, for example, be engraved. To do this, simply unhook the system by disengaging the parts 14 and 16, and turn the box 180 ° around the axis of the setting rod hour 18. By doing so, we transform the watch into a jewel, with, however, the same appearance of the bracelet. It will be noted that such a solution is not applicable only insofar as the members 14 and 16 present a plan of symmetry, passing through the two sliding axes.

    Il est également possible de ne désenclencher le système que d'un côté, puis de fléchir le bracelet et le crocher de manière à ce que la glace soit masquée et que l'autre face du bracelet soit apparente. En procédant ainsi, il est possible de modifier encore plus l'aspect de la montre, dans la mesure où les deux faces du bracelet sont différentes.It is also possible to switch off the system only on one side, then bend the bracelet and hook it so that the ice is hidden and that the other side of the bracelet is visible. By doing so, it is possible to further modify the appearance of the watch, insofar as the two faces of the bracelet are different.

    La figure 3c montre une troisième variante, dans laquelle la montre a été remplacée par un objet décoratif 42, qui n'a qu'une fonction esthétique. Cet objet comporte, à l'instar de la boíte, des organes 14 permettant la fixation au bracelet. Figure 3c shows a third variant, in which the watch was replaced by a decorative object 42, which has only an aesthetic function. This object includes, like the box, members 14 for attachment to bracelet.

    Ainsi, grâce aux caractéristiques du système tel que décrit, il est possible de réaliser une montre dans laquelle la fixation du bracelet à la boíte joue le rôle de fermoir. La montre peut, en outre être susceptible de présenter des aspects différents, par des moyens simples et économiques.Thus, thanks to the characteristics of the system as described, it is possible to make a watch in which the attachment of the bracelet to the box plays the role of clasp. The watch may also be liable to have aspects different, by simple and economical means.

    Il va de soi qu'un tel système peut faire l'objet de nombreuses variantes sans, pour autant, sortir du cadre de l'invention. Il serait ainsi possible de réaliser une boíte de forme ronde. Dans ce cas, la direction de coulissement serait définie par un arc plutôt qu'une droite.It goes without saying that such a system can be the subject of numerous variants without, however, depart from the scope of the invention. It would thus be possible to carry out a round shape box. In this case, the sliding direction would be defined by an arc rather than a straight line.

    Il est aussi possible de placer deux mouvements dans la boíte de montre, ces mouvements pouvant, par exemple, comporter des fonctions différentes ou afficher les heures de deux fuseaux horaires.It is also possible to place two movements in the watch case, these movements which may, for example, have different functions or display the hours of two time zones.
