Description

La présente invention se rapporte à une boíte de montre comportant une lunette tournante montée à cran sur une bague solidaire d'une carrure de la boíte, et des moyens de positionnement pour maintenir la lunette dans des positions angulaires prédéterminées, la bague présentant en section transversale un fond qui s'étend sensiblement dans un plan radial, perpendiculaire à un axe central de la boíte, et un rebord extérieur ayant un profil externe sur lequel la lunette est montée à cran de façon à être centrée et retenue dans une direction parallèle audit axe, les moyens de positionnement comportant une denture disposée sur une face inférieure de la lunette et au moins un cliquet agencé pour s'engager dans la denture, ledit cliquet étant formé par une lame flexible dans la direction dudit axe.The present invention relates to a box of watch with a rotating bezel mounted on a notch on a ring secured to a middle part of the box, and positioning means for holding the telescope in predetermined angular positions, the ring having in cross section a bottom which extends substantially in a radial plane, perpendicular to an axis central of the box, and an outer rim having a external profile on which the telescope is mounted so as to be centered and held in one direction parallel to said axis, the positioning means having teeth arranged on a lower face of the telescope and at least one pawl arranged to engage in the teeth, said pawl being formed by a blade flexible in the direction of said axis.

Une boíte de montre munie d'une lunette tournante supportée par la carrure au moyen d'un système de bagues est connue. Par exemple selon le brevet CH 677 713, la lunette est maintenue sur la carrure par une bague métallique à section en L présentant une surface tronconique externe sur laquelle la lunette est montée à cran. Cette bague comporte un dégagement annulaire destiné à recevoir une bague-ressort. Des cliquets sont découpés dans la bague-ressort et agissent axialement sur la denture inférieure de la lunette. Cette denture est formée par des découpes traversant une partie inférieure de la lunette. Ce système, bien qu'assurant le centrage et le positionnement de la lunette, présente des désavantages principalement pour le montage, car il comporte différentes pièces, à savoir une bague métallique maintenant une autre bague pour le montage du verre et portant elle-même sur son fond ladite bague-ressort à cliquets.A watch case fitted with a rotating bezel supported by the middle by means of a ring system is known. For example according to patent CH 677 713, the bezel is held on the middle by a ring metallic L-shaped section with a surface external frustoconical on which the telescope is mounted at notch. This ring has an annular clearance intended to receive a spring ring. Ratchets are cut out in the spring ring and act axially on the lower teeth of the bezel. This toothing is formed by cutouts crossing a lower part of the glasses. This system, although ensuring centering and positioning of the telescope has disadvantages mainly for mounting, because it includes different parts, namely a metal ring now another ring for mounting the glass and itself bearing on its bottom said spring ring to pawls.

Il est connu du brevet CH 631 592 un système de fixation d'une lunette tournante comportant sur sa face inférieure un bourrelet qui est retenu par crantage sur une carrure comprenant un bourrelet annulaire analogue. Ledit système comprend aussi un ressort-lame fixé à la carrure. Le ressort-lame porte des cliquets qui exercent une pression axiale sur la denture de la lunette, de sorte que les deux bourrelets mentionnés ci-dessus s'appuient l'un contre l'autre selon un cône de tangence et assurent par friction le blocage de la lunette en position de repos. Ce système n'est néanmoins pas simple à réaliser car il nécessite un usinage précis des bourrelets sur la carrure et sur la lunette. De plus, le montage de la lunette est délicat, à cause de la grande rigidité du bourrelet de la carrure.It is known from patent CH 631 592 a system of fixing of a rotating bezel comprising on its face lower a bead which is retained by notching on a middle part comprising a similar annular bead. The system also includes a leaf spring attached to the middle. The leaf spring carries pawls which exert axial pressure on the teeth of the telescope, so that the two beads mentioned above are supported one against the other according to a tangency cone and ensure by friction blocking the telescope in position rest. However, this system is not easy to implement because it requires precise machining of the beads on the middle and on the bezel. In addition, the mounting of the bezel is delicate, due to the high rigidity of the bead of the middle.

Il est également connu du brevet CH 665 522 un système de retenue d'une lunette sur une carrure au moyen d'une seule pièce pourvue de cliquets agissant radialement sur une surface inférieure de ladite lunette. Cette action radiale ne permet pas, par opposition aux deux brevets précédents où l'action des cliquets est axiale, d'obtenir sur la lunette une pression participant au positionnement et au maintien par coincement de ladite lunette.It is also known from patent CH 665 522 a restraint system for a bezel on a middle by means in one piece with radially acting pawls on a lower surface of said telescope. This action radial does not allow, as opposed to the two patents precedents where the action of the pawls is axial, to obtain pressure on the telescope participating in positioning and holding said bezel by jamming.

La présente invention vise à réaliser un système muni de cliquets axiaux et permettant de monter à cran une lunette tournante sur une carrure. L'objectif recherché est d'obtenir une fabrication et un montage dudit système relativement simples et peu coûteux à mettre en oeuvre. Ledit système muni de cliquets doit notamment assurer toutes les fonctions de centrage, de retenue et de positionnement angulaire de ladite lunette.The present invention aims to achieve a system fitted with axial pawls and making it possible to mount a notch rotating bezel on a middle. The objective sought is to obtain a manufacture and an assembly of said system relatively simple and inexpensive to implement. Said system provided with pawls must in particular ensure all functions of centering, retaining and angular positioning of said telescope.

Dans ce but, l'invention concerne une boíte de montre du type défini plus haut, caractérisée en ce que la lame flexible est faite d'une seule pièce avec la bague, la lame étant découpée dans le fond de ladite bague.To this end, the invention relates to a watch case of the type defined above, characterized in that the blade flexible is made in one piece with the ring, the blade being cut from the bottom of said ring.

Ainsi la présence invention permet de réaliser ensemble des fonctions précédemment citées avec une seule et même bague, dans le fond de laquelle chaque lame flexible servant de cliquet peut être facilement découpée. La fabrication de cette bague est relativement simple, il est par exemple aisé de la fabriquer entièrement par étampage. Elle est d'autre part peu coûteuse à mettre en oeuvre et permet notamment d'importantes économies de matière et de temps parce que sa réalisation industrielle est facile. Le montage de la bague sur la carrure de la montre présente les mêmes avantages de simplicité de mise en oeuvre et de coût car la bague peut, par exemple, être directement chassée sur la carrure.Thus the presence of the invention makes it possible to realize set of previously mentioned functions with a single and same ring, in the bottom of which each blade flexible serving as a ratchet can be easily cut. The manufacture of this ring is relatively simple, it is for example easy to manufacture it entirely by stamping. It is also inexpensive to set up. works and allows in particular significant savings of matter and time because its industrial realization is easy. The mounting of the ring on the middle of the watch has the same advantages of simplicity of setting and cost because the ring can, for example, be directly driven onto the middle.

D'autres caractéristiques et avantages de cette invention apparaítront dans la description suivante d'une forme de réalisation préférée d'une boíte de montre à lunette tournante selon l'invention, en référence aux dessins annexés, dans lesquels :

  • la figure 5 est une vue en coupe selon la ligne V-V de la figure 3, et
  • la figure 6 est une vue en coupe selon la ligne VI-VI de la figure 3.
Other characteristics and advantages of this invention will appear in the following description of a preferred embodiment of a watch case with a rotating bezel according to the invention, with reference to the appended drawings, in which:
  • FIG. 1 represents a partial view in axial section of a watch with a rotating bezel according to the present invention;

La figure 1 illustre une boíte de montre 6 comprenant, sur sa face supérieure 1, une lunette tournante 2 montée sur une carrure 4 de la boíte 6 grâce à une bague 8 fixée sur ladite carrure 4. La carrure 4 présente dans sa partie supérieure un épaulement 10 sensiblement en forme de L, ayant une surface sensiblement cylindrique et verticale 10a et une surface sensiblement plane et horizontale 10b. La lunette 2 est rotative autour d'un axe central 11 perpendiculaire à la face supérieure 1 de la boíte 6. Elle est faite d'une unique pièce comprenant une partie haute, ayant une face supérieure 12 et une face inférieure 14, et une partie latérale 16 descendant vers la carrure 4.Figure 1 illustrates a watch case 6 comprising, on its upper face 1, a telescope rotating 2 mounted on a middle part 4 of the box 6 thanks to a ring 8 fixed to said middle part 4. The middle part 4 has a shoulder 10 in its upper part substantially L-shaped, having a substantially surface cylindrical and vertical 10a and a surface substantially flat and horizontal 10b. Bezel 2 is rotatable around a central axis 11 perpendicular to the upper face 1 box 6. It is made in one piece comprising an upper part, having an upper face 12 and a lower face 14, and a lateral part 16 descending towards the middle 4.

La bague 8 a, dans le mode de réalisation préféré, une section transversale en forme générale de U d'épaisseur approximativement uniforme, cette section comprenant une partie latérale verticale 17 (figures 4 et 5) située à l'intérieur et appliquée fortement contre la surface verticale 10a de la carrure, un fond 18 horizontal appliqué sur la surface horizontale 10b de la carrure, et une partie latérale extérieure en forme de rebord bombé dont le profil externe 20 est caractérisé par deux surfaces tronconiques d'inclinaisons opposées 20a et 20b (figure 5), formant ainsi une proéminence vers l'extérieur.The ring 8 has, in the preferred embodiment, a generally U-shaped cross section of approximately uniform thickness, this section comprising a vertical lateral part 17 (FIGS. 4 and 5) located inside and applied strongly against the vertical surface 10a of the middle part, a horizontal bottom 18 applied to the horizontal surface 10b of the middle part, and an outer side part in the shape of a curved edge whose external profile 20 is characterized by two frustoconical surfaces of opposite inclinations 20a and 20b (Figure 5), thus forming a prominence towards outside.

L'épaulement 10 de la carrure 4 est destiné à recevoir la bague 8, les surfaces verticales de la carrure et de la bague permettant de monter la bague 8 en chassant directement celle-ci sur la carrure. Ce mode de fixation est très rapide et permet d'éviter le recours à des ergots ou d'autres organes pour empêcher une rotation de la bague et des cliquets.The shoulder 10 of the middle part 4 is intended for receive the ring 8, the vertical surfaces of the middle part and the ring for mounting the ring 8 while driving directly on the middle. This method of attachment is very fast and avoids the use of pins or other means to prevent rotation of the ring and pawls.

La lunette 2 comporte sur sa face supérieure 12 des inscriptions propres à sa fonction et sur sa face inférieure une denture 22, comportant par exemple soixante dents réparties sur la circonférence de la lunette. La partie latérale 16 de la lunette présente sur sa face interne deux surfaces tronconiques 24a et 24b d'inclinaisons opposées, en face des surfaces tronconiques 20a et 20b de la bague.The bezel 2 has on its upper face 12 inscriptions specific to its function and on its face lower a toothing 22, for example comprising sixty teeth distributed around the circumference of the bezel. The lateral part 16 of the bezel present on its face internal two frustoconical surfaces 24a and 24b of opposite inclinations, opposite the frustoconical surfaces 20a and 20b of the ring.

Des lames flexibles 26, jouant le rôle de cliquets, sont découpées à travers le fond plat 18 de la bague 8 et sont relevées axialement, c'est-à-dire dans la direction de l'axe central 11, vers la denture 22 de la lunette, de sorte que leurs extrémités libres s'y engagent par élasticité pour assurer le positionnement angulaire de la lunette 2. La pression axiale que les lames flexibles 26 exercent sur la denture 22 lorsque la lunette est en position de repos a pour effet d'appuyer la surface tronconique inférieure 24b de sa face interne contre la surface tronconique inférieure 20b du profil externe 20 de la bague.Flexible blades 26, playing the role of pawls, are cut through the flat bottom 18 of the ring 8 and are raised axially, i.e. in the direction from the central axis 11, towards the teeth 22 of the telescope, so that their free ends engage with it by elasticity to ensure the angular positioning of the bezel 2. The axial pressure as the flexible blades 26 exert on the teeth 22 when the bezel is in rest position has the effect of pressing the surface frustoconical lower 24b of its internal face against the lower frustoconical surface 20b of the external profile 20 of the ring.

Dans cette position de repos, la lunette 2 est maintenue axialement et radialement en position centrée sur la carrure 4 de la boíte 6 de la montre, et en outre la faible conicité des surfaces 20b et 24b assure un léger coincement qui empêche une rotation intempestive de la lunette. Un jeu subsiste alors entre les surfaces tronconiques supérieures 20a et 24a. Le porteur de la montre peut positionner la lunette tournante 2 simplement en exerçant une pression axiale vers le bas avant de la faire tourner.In this rest position, the telescope 2 is held axially and radially in centered position on the middle part 4 of the case 6 of the watch, and in addition the low taper of the surfaces 20b and 24b ensures a slight jamming which prevents untimely rotation of the glasses. A play then remains between the surfaces upper frustoconical 20a and 24a. The bearer of the watch can position the rotating bezel 2 simply by exerting an axial downward pressure before the turn.

Les figures 2 à 6 représentent la bague 8 telle que décrite précédemment avec, dans ce mode de réalisation, quatre lames flexibles 26 utilisées comme cliquets, ces lames étant de préférence diamétralement opposées deux à deux afin d'agir simultanément sur la lunette. L'extrémité libre des lames flexibles 26 est droite et s'engage par élasticité dans la denture 22 de la lunette 2, qui peut alors n'être mise en rotation que dans une seule direction. La direction de rotation est déterminée par le sens dans lequel sont réalisées les lames flexibles 26 et la denture 22 de la lunette. Néanmoins une rotation bidirectionnelle peut être obtenue si l'extrémité libre des lames 26 est coudée vers le fond 18 de la bague 8, comme illustré dans le brevet CH 631 592.Figures 2 to 6 show the ring 8 as described above with, in this embodiment, four flexible blades 26 used as pawls, these blades preferably being diametrically opposite two to two to act simultaneously on the telescope. The end free flexible blades 26 is straight and engages by elasticity in the teeth 22 of the bezel 2, which can then only be rotated in one direction. The direction of rotation is determined by the direction in which the flexible blades 26 and the teeth 22 of the bezel. Nevertheless a rotation bidirectional can be obtained if the free end blades 26 is bent towards the bottom 18 of the ring 8, as illustrated in patent CH 631 592.

Les figures 4 et 5 représentent des coupes de la bague 8 où l'on distingue le profil externe 20 caractérisé par les deux surfaces tronconiques d'inclinaisons opposées 20a et 20b. Ainsi, la lunette tournante 2 peut être facilement montée à cran par-dessus cette bague grâce à l'élasticité de la bague et/ou de la lunette. La figure 4 fait aussi apparaítre une des lames flexibles 26 ainsi que l'ouverture 28 créée dans le fond 18 de la bague par le découpage de la lame.Figures 4 and 5 show sections of the ring 8 where we distinguish the external profile 20 characterized by the two frustoconical surfaces of opposite inclinations 20a and 20b. Thus, the rotating bezel 2 can be easily mounted notch over this ring thanks to the elasticity of the ring and / or of the bezel. Figure 4 also shows up one of the flexible blades 26 as well as the opening 28 created in the bottom 18 of the ring by the cutting the blade.

La figure 6 est une coupe tangentielle montrant plus en détail le profil longitudinal d'une des lames flexibles 26.Figure 6 is a tangential section showing more in detail the longitudinal profile of one of the flexible blades 26.

La bague 8 et la lunette tournante 2 peuvent être réalisées en métal, mais aussi en matière synthétique. En outre, la lunette et la carrure peuvent être réalisées en une ou plusieurs pièces. La lunette peut être amovible ou non.The ring 8 and the rotating bezel 2 can be made of metal, but also of synthetic material. In in addition, the bezel and the middle part can be produced in one or more pieces. The bezel can be removable or no.

La description du mode de réalisation préféré dans l'exemple ci-dessus montre que la présente invention permet d'obtenir une fabrication et un montage relativement simples et peu coûteux à mettre en oeuvre. La bague est une pièce relativement simple à réaliser industriellement, de même son montage sur la carrure peut facilement être réalisé par chassage. Toutefois la bague peut être fixée sur la carrure d'une autre manière, par exemple par collage ou par soudage. Le nombre de lames flexibles 26 peut être quelconque, mais de préférence au moins égal à deux pour des raisons de symétrie des forces exercées sur la lunette.The description of the preferred embodiment in the example above shows that the present invention allows for manufacturing and mounting relatively simple and inexpensive to implement. The ring is a relatively simple piece to make industrially, likewise its mounting on the middle part can easily be achieved by hunting. However the ring can be fixed to the middle in another way, by example by gluing or welding. The number of blades flexible 26 can be any, but preferably at less than two for reasons of symmetry of forces exerted on the telescope.
