Abstract

Watchstrap made up of hinged links and pins. The links are made up of inner (10) and outer (12) plates with gaps or interstices (11, 13, 15) between them. Interstices of a first type (11, 13) have a width of greater than 0.15 mm, while the width of the second type is less than 0.05 mm. The first interstices are transverse, while the second interstices are longitudinal.

Description

La présente invention se rapporte aux bracelets à maillons pour montres, comportant des goupilles et des plaquettes en matériau rigide disposées côte à côte.The present invention relates to watch strap bracelets, comprising pins and plates of rigid material arranged side by side side.

Dans ces bracelets, les maillons sont formés de plaquettes, et de goupilles reliant au moins deux plaquettes voisines de manière articulée, les axes des goupilles définissant des axes de pivotement.In these bracelets, the links are formed of plates, and pins connecting at least two adjacent plates in an articulated manner, the axes of the pins defining pivot axes.

De tels bracelets sont bien connus de l'homme du métier. Ils présentent l'avantage d'être extrêmement solides et d'offrir de nombreuses possibilités de formes, conférant à la montre une esthétique particulière. L'un d'entre eux est, par exemple, décrit dans le document EP 0749 709.Such bracelets are well known to those skilled in the art. They present the advantage of being extremely solid and offering many possibilities for shapes, giving the watch a particular aesthetic. One of them is, for example, described in document EP 0749 709.

Du fait que les bracelets sont formés de maillons articulés les uns aux autres, il existe obligatoirement un interstice entre les plaquettes voisines. En effet, si les plaquettes étaient en contact direct l'une avec l'autre, sans espace, elles ne pourraient avoir de mouvements relatifs.Because the bracelets are made up of hinged links, there must be a gap between the neighboring plates. Indeed, if the pads were in direct contact with each other, with no space, they did not could have relative movements.

Ce genre de bracelets pose toutefois un problème pour une part importante de la population, car la largeur des interstices dépend du rayon de courbure du bracelet. Ce rayon est fonction du diamètre du poignet du porteur. Il peut, en outre, varier lors du porter, sous l'effet de chocs violents par exemple. Lorsque la largeur de l'interstice est inférieure au diamètre du poil, ce dernier est pincé, et arraché si le bracelet est déplacé, ce qui est désagréable. Le but de la présente invention est de pallier cet inconvénient.However, this type of bracelet poses a problem for a large part of the population, because the width of the interstices depends on the radius of curvature of the bracelet. This radius is a function of the wearer's wrist diameter. He can, in in addition, vary when wearing, under the effect of violent shocks for example. When the width of the gap is less than the diameter of the hair, the latter is pinched, and torn off if the bracelet is moved, which is unpleasant. The purpose of this invention is to overcome this drawback.

A cet effet, le bracelet selon l'invention comporte des interstices de deux types, dont ceux du premier type présentent, en permanence, une largeur supérieure à 0,15 mm, et dont ceux du second type présentent, en permanence, une largeur inférieure à 0,05 mm dans les zones affleurant la surface apparente du bracelet, c'est-à-dire les ouvertures par lesquelles les poils sont susceptibles de se glisser dans l'interstice.To this end, the bracelet according to the invention comprises interstices of two types, of which those of the first type permanently have a width greater than 0.15 mm, and of which those of the second type have, permanently, a width less than 0.05 mm in the areas flush with the apparent surface of the bracelet, i.e. the openings through which the bristles are likely to slip in the gap.

Avec une telle configuration, il est pratiquement impossible que des poils se prennent dans l'un ou l'autre des interstices, car leur diamètre est de l'ordre de 0,10 mm. De la sorte, le poil est trop petit pour rester coincé dans un interstice de premier type et trop grand pouvoir s'introduire dans un interstice de second type.With such a configuration, it is practically impossible for hairs to get take in one or the other of the interstices, because their diameter is of the order of 0.10 mm. In this way, the hair is too small to get stuck in a gap of the first type and too great a power to enter a gap of the second type.

Comme expliqué plus haut, la largeur des interstices est fonction du rayon de courbure du bracelet. Une solution simple permettant d'éviter que le bracelet ne soit trop fermé et, en conséquence, que les interstices de premier type ne se resserrent trop, les plaquettes ont un mouvement limité. A cet effet, deux plaquettes voisines comportent l'une un organe mâle, l'autre un organe femelle, ces organes coopérant l'un avec l'autre pour former une butée.As explained above, the width of the interstices is a function of the radius of curvature of the bracelet. A simple solution to prevent the bracelet from is too closed and, consequently, that the interstices of the first type do not tighten too much, the pads have limited movement. For this purpose, two neighboring wafers include one a male organ, the other a female organ, these bodies cooperating with each other to form a stop.

De manière avantageuse, les interstices définis par des parois de plaquettes sensiblement parallèles aux axes de pivotement, appelés ci-après interstices parallèles, sont de premier type, et les interstices définis par des parois sensiblement perpendiculaires à ces axes, appelés ci-après interstices perpendiculaires, sont de deuxième type.Advantageously, the interstices defined by walls of platelets substantially parallel to the pivot axes, hereinafter called interstices are of the first type, and the interstices defined by walls substantially perpendicular to these axes, hereinafter called interstices perpendicular, are of the second type.

Il a, en effet, été constaté que la largeur des interstices parallèles varie en fonction du rayon de courbure du bracelet. Si cette largeur devait être comprise entre 0 et 0,05 mm, le mouvement relatif des plaquettes serait très limité, ce qui affecterait le confort au porter. C'est pourquoi il est préférable que la largeur de ces interstices soit toujours supérieure à 0,15 mm.It has in fact been observed that the width of the parallel interstices varies in function of the radius of curvature of the bracelet. If this width were to be understood between 0 and 0.05 mm, the relative movement of the pads would be very limited, which would affect wearing comfort. This is why it is preferable that the width of these gaps are always greater than 0.15 mm.

Par ailleurs, les interstices perpendiculaires ont une largeur qui peut varier à cause de l'ébat existant entre les maillons voisins. Cet ébat est déterminé par les mouvements relatifs de translation que peuvent avoir ces maillons entre deux positions extrêmes, dans lesquelles les plaquettes sont en contact l'une avec l'autre. En d'autres termes, dans ces deux positions, un interstice a une largeur égale à zéro, soit obligatoirement inférieure à 0,15 mm. C'est pourquoi, pour éviter le pincement de poils, il faut que cette largeur soit, en permanence inférieure à 0,05 mm, c'est-à-dire que l'interstice soit de deuxième type.Furthermore, the perpendicular interstices have a width which can vary because of the gap between the neighboring links. This frolic is determined by the relative translational movements that these links can have between two extreme positions, in which the pads are in contact with each other the other. In other words, in these two positions, a gap has a width equal to zero, which must be less than 0.15 mm. This is why, for avoid pinching hairs, this width must be permanently less than 0.05 mm, that is to say that the gap is of the second type.

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

  • 1. la figure 1 montre, vu de dessus, une portion d'un bracelet selon l'invention,
  • 2. la figure 2, représente dans une vue en perspective, en a une plaquette médiane et en b une plaquette latérale du bracelet de la figure 1, et
  • 3. la figure 3 est une vue en coupe, en a perpendiculaire et, en b parallèle à un axe d'articulation.
    • Other advantages and characteristics of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  • 1. FIG. 1 shows, seen from above, a portion of a bracelet according to the invention,
  • 2. Figure 2 shows in a perspective view, has a central plate and a side plate b of the bracelet of Figure 1, and
  • 3. Figure 3 is a sectional view, at a perpendicular and, at b parallel to an axis of articulation.

    • Le bracelet, partiellement représenté sur la figure 1, est formé de trois ensembles de pièces identiques, soit des plaquettes médianes 10, des plaquettes latérales 12 et de goupilles 14.The bracelet, partially shown in Figure 1, is formed of three sets of identical parts, namely middle plates 10, plates side 12 and pins 14.

    Les plaquettes 10 sont disposées dans la partie médiane du bracelet et définissent, entre elles, un interstice 11. Les plaquettes 12 sont disposées dans les bords latéraux du bracelet et définissent, entre elles, un interstice 13. Les plaquettes 10 et 12 voisines définissent également des interstices, qui portent la référence 15.The plates 10 are arranged in the middle part of the bracelet and define, between them, a gap 11. The plates 12 are arranged in the lateral edges of the bracelet and define between them a gap 13. The neighboring plates 10 and 12 also define interstices, which bear the reference 15.

    Une plaquette 10 est représentée sur la figure 2a. Elle est de forme générale parallélépipédique, avec une face supérieure 10a, une face inférieure 10b, deux faces longitudinales 10c et deux faces latérales 10d. Elle est percée de deux trous cylindriques 16 dont l'axe est orienté parallèlement aux faces longitudinales 10c et qui débouchent, tous les deux, dans les deux faces latérales 10d. Ces trous ont un diamètre légèrement supérieur au diamètre des goupilles 14.A plate 10 is shown in Figure 2a. It is of general shape parallelepiped, with an upper face 10a, a lower face 10b, two longitudinal faces 10c and two lateral faces 10d. It is pierced with two cylindrical holes 16 whose axis is oriented parallel to the faces longitudinal 10c and which both open on both sides side 10d. These holes have a diameter slightly larger than the diameter of the pins 14.

    Les faces longitudinales 10c sont munies de biseaux 10e dans leur partie voisine de la face supérieure 10a.The longitudinal faces 10c are provided with bevels 10e in their part adjacent to the upper face 10a.

    Les faces latérales 10d comportent, chacune, une gorge 18, de section rectangulaire, qui s'étend de l'une à l'autre des faces longitudinales 10c et forme un organe femelle. Chaque gorge 18 comprend un fond 18a et deux parois, l'une supérieure 18b, l'autre inférieure 18c, dont la fonction sera précisée plus loin. Elle présente une largeur L, mesurée entre les parois 18b et 18c,The lateral faces 10d each have a groove 18, of rectangular section, which extends from one to the other of the longitudinal faces 10c and forms a female member. Each groove 18 comprises a bottom 18a and two walls, one upper 18b, the other lower 18c, the function of which will be specified below. It has a width L , measured between the walls 18b and 18c,

    La plaquette 12, représentée sur la figure 2b, est également de forme générale parallélépipédique. Elle comporte une face supérieure 12a, une face inférieure 12b, deux faces longitudinales 12c et deux faces latérales 12d et 12e. La face latérale 12d et percée de deux trous borgnes cylindriques 20 dont les axes sont parallèles aux faces longitudinales 12c. Ces trous ont un diamètre légèrement inférieur à celui des goupilles 14.The plate 12, shown in Figure 2b, is also of general shape cuboid. It has an upper face 12a, a lower face 12b, two longitudinal faces 12c and two lateral faces 12d and 12e. The face lateral 12d and pierced with two cylindrical blind holes 20 whose axes are parallel to the longitudinal faces 12c. These holes have a slightly diameter lower than that of pins 14.

    Les faces longitudinales 12c sont munies de biseaux 12f dans leurs portions voisines de la face supérieure 12a.The longitudinal faces 12c are provided with bevels 12f in their portions adjacent to the upper face 12a.

    La face latérale 12d porte, en outre, deux doigts 22, formant des organes mâles et disposés dans l'alignement des faces longitudinales, chacun adjacent à l'un des trous 20. Chaque doigt 22 comporte une face supérieure 22a et une face inférieure 22b. Il présente une épaisseur E, égale à la distance comprise entre ses faces inférieures 22b et supérieures 22a.The side face 12d further carries two fingers 22, forming male members and arranged in alignment with the longitudinal faces, each adjacent to one of the holes 20. Each finger 22 has an upper face 22a and a lower face 22b . It has a thickness E , equal to the distance between its lower faces 22b and upper 22a.

    Les goupilles 14, dont l'une seulement est partiellement visible sur la figure 1, sont formées de tiges d'acier inoxydable de forme cylindrique, dont la section peut être circulaire ou non. Il est par exemple possible d'utiliser des goupilles du type défini dans le document EP 0749 709 mentionné plus haut. Leur section est choisie de manière à ce qu'elles puissent être chassées à forces dans les trous borgnes 20 alors qu'elles pivotent librement, avec un jeu minimum, dans les trous 16 des plaquettes 10.The pins 14, only one of which is partially visible in FIG. 1, are made of cylindrical stainless steel rods, the cross section of which can be circular or not. It is for example possible to use pins of the type defined in the document EP 0749 709 mentioned above. Their section is chosen so that they can be forced out in the blind holes 20 while they pivot freely, with minimum play, in the holes 16 of the plates 10.

    L'assemblage du bracelet se fait en chassant tout d'abord les goupilles 14 dans les trous borgnes 20 d'une première partie des plaquettes 12, formant ainsi des pièces en U. Les plaquettes 10 sont ensuite mises en place, une plaquette 10 pour chaque barre du U et chaque plaquette 10 enfilée sur deux goupilles 14. La deuxième partie des plaquettes 12 est alors chassée en regard des plaquettes de la première moitié, de manière à ce que les pièces en U deviennent des pièces en O. Cet assemblage forme ainsi une chaíne faite de deux sortes de maillons, respectivement constitués des plaquettes 10 et des pièces en O, chaque plaquette 10 formant deux charnière, avec les goupilles 14 qui la traverse, comme représenté sur la figure 1.The bracelet is assembled by first driving out the pins 14 in the blind holes 20 of a first part of the plates 12, thus forming U-shaped pieces. The plates 10 are then put in place, a plate 10 for each U bar and each plate 10 threaded on two pins 14. The second part of the plates 12 is then driven opposite the plates of the first half, so that the U-shaped pieces become pieces in O. This assembly thus forms a chain made of two kinds of links, respectively made up of plates 10 and O-shaped parts, each plate 10 forming two hinges, with the pins 14 which crosspiece, as shown in Figure 1.

    Dans cette disposition, les doigts 22, tenant lieu d'organes mâles, sont logés dans les gorges 18 formant des organes femelles. La largeur L de ces gorges est sensiblement plus grande que l'épaisseur E des doigts. De la sorte, le mouvement de rotation de la charnière est interrompu lorsque l'un des doigts vient en butée contre l'une des parois 18b, 18c de la gorge 18.In this arrangement, the fingers 22, taking the place of male organs, are housed in the grooves 18 forming female organs. The width L of these grooves is substantially greater than the thickness E of the fingers. In this way, the rotational movement of the hinge is interrupted when one of the fingers abuts against one of the walls 18b, 18c of the groove 18.

    Pour bien comprendre la manière dont se fait l'articulation, on peut se référer à la figure 3, qui représente, en a, une coupe passant par les doigts 22, et la gorge 18, le plan de coupe passant dans l'interstice 15 compris entre les plaquettes 10 et 12, correspondant à la ligne A-A de la figure 3b. Sur cette figure, les deux plaquettes 10 visibles se trouvent dans la position qu'elles occupent lorsque le bracelet présente son rayon de courbure le plus faible. On y constate que les faces supérieures 22a des doigts 22 sont en appui contre la face supérieure 18b des gorges 18. To understand the way in which the articulation is made, one can refer to FIG. 3, which represents, in a , a section passing through the fingers 22, and the groove 18, the section plane passing through the gap 15 between plates 10 and 12, corresponding to line AA in Figure 3b. In this figure, the two visible plates 10 are in the position they occupy when the bracelet has its smallest radius of curvature. It can be seen there that the upper faces 22a of the fingers 22 are in abutment against the upper face 18b of the grooves 18.

    Dans cette position, l'interstice 11, défini les faces longitudinales 10c et les biseaux 10e, a une largeur d'environ 0,20 mm au voisinage des faces inférieures 10b et s'élargit au voisinage des faces supérieures 10a, à cause des biseaux 10e.In this position, the gap 11, defined the longitudinal faces 10c and the bevels 10e, has a width of approximately 0.20 mm in the vicinity of the lower faces 10b and widens in the vicinity of the upper faces 10a, because of the bevels 10e.

    Lorsque le bracelet est ouvert, de manière à avoir un rayon de courbure maximum, l'interstice 11 se rétrécit dans la partie supérieure, les biseaux 10e étant alors sensiblement parallèles entre eux, et s'élargit dans sa partie inférieure, sa largeur passant d'environ 0,15 mm dans la partie supérieure à 0,25 mm dans la partie inférieure.When the bracelet is open, so as to have a radius of curvature maximum, gap 11 narrows at the top, bevels 10e then being substantially parallel to each other, and widens in its part lower, its width going from about 0.15 mm in the upper part to 0.25 mm at the bottom.

    Les faces longitudinales 12c des maillons 12 sont disposées de manière que les interstices 13 soient tout à fait comparable dans leurs largeurs aux interstices 11, de manière à ce que celle-ci soit toujours supérieure à 0,15 mm.The longitudinal faces 12c of the links 12 are arranged so that the interstices 13 are quite comparable in their widths to interstices 11, so that it is always greater than 0.15 mm.

    La figure 3b représente une portion du bracelet coupé par un plan passant par l'axe d'une goupille 14, chassée à chacune de ses extrémités dans l'un des trous 20 d'une plaquette 12 et engagée, libre en rotation, dans l'un des trous 16 d'une plaquette 10. Les plaquettes 10 et 12 sont séparées par un interstice 15, défini par les parois 10d et 12d contiguës et dont la largeur e est inférieure à 0,05 mm. Cette largeur ne varie pas en fonction du rayon de courbure du bracelet. Cela est dû au fait que les parois 10d et 12d sont perpendiculaires à l'axe de la charnière. Elle peut, par contre changer du fait que la plaquette 10 est monté libre sur la goupille 14 et qu'elle peut se déplacer jusqu'à être en contact avec la plaquette 12 de l'un ou l'autre côté. Dans tous les cas, la largeur e de l'interstice 15 reste inférieur à 0,05 mm.FIG. 3b represents a portion of the bracelet cut by a plane passing through the axis of a pin 14, driven at each of its ends into one of the holes 20 of a plate 12 and engaged, free to rotate, in the 'one of the holes 16 of a plate 10. The plates 10 and 12 are separated by a gap 15, defined by the adjoining walls 10d and 12d and whose width e is less than 0.05 mm. This width does not vary depending on the radius of curvature of the bracelet. This is due to the fact that the walls 10d and 12d are perpendicular to the axis of the hinge. On the other hand, it can change because the plate 10 is mounted freely on the pin 14 and that it can move until it is in contact with the plate 12 on either side. In all cases, the width e of the gap 15 remains less than 0.05 mm.

    L'invention, telle que décrite, peut, bien entendu, faire l'objet de nombreuses variantes. La fonction de butée, limitant le mouvement relatif des plaquettes, peut ainsi être obtenue de nombreuses autres façons. Il est possible de réaliser les doigts au moyen de pièces rapportées plutôt que par usinage de la plaquette. The invention, as described, can, of course, be the subject of numerous variants. The stop function, limiting the relative movement of the pads, can be obtained in many other ways as well. It is possible to realize fingers by means of inserts rather than by machining the insert.

    Il est également possible d'engager le doigt dans un trou rond plutôt que dans une gorge.It is also possible to engage the finger in a round hole rather than in a throat.

    Par ailleurs, la fixation des plaquettes 12 aux goupilles 14 peut être envisagée de nombreuses autres façons, par exemple par vissage, collage ou soudage.Furthermore, the attachment of the plates 12 to the pins 14 can be envisaged in many other ways, for example by screwing, gluing or welding.
