Abstract

The molded ring fills all space remaining between watch ring and casing. The watch comprises a casing (2) and a surrounding circle (3) with a base (7). This encloses the movement (4) with an adjusting shaft (10). A circular sealing ring (12) surrounds the adjusting shaft, which extends to a recess which is formed in the outside of the casing to receive the watch adjuster. Elastomer material (9) is molded in position within the casing, filling the entire space between the surrounding circuit and the casing.

Description

La présente invention concerne un procédé selon préambule de la revendication 1.The present invention relates to a method according to the preamble of claim 1.

Il est connu, dans le domaine des garde-temps et plus particulièrement des montres-bracelets, de disposer certains éléments de la montre tels que mouvement, cadran ou lunette dans un cercle d'encageage qui est inséré dans la carrure de la montre comme décrit par exemple dans CH 681'127.It is known, in the field of timepieces and more particularly of wristwatches, to arrange certain elements of the watch such as movement, dial or bezel in a casing circle which is inserted in the middle of the watch as described for example in CH 681'127.

Dans le cas d'une montre étanche, il est connu d'insérer une pluralité de joints d'étanchéité en matériau élastomère au niveau du fond, de la tige et de la glace de montre.In the case of a waterproof watch, it is known to insert a plurality of seals sealing in elastomeric material at the bottom, the rod and the glass of watch.

Bien que les opérations d'usinage intérieur de la carrure soient simplifiées par l'interposition du cercle d'encageage, il subsiste des difficultés qui n'ont jamais été résolues de façon satisfaisante; en particulier, pour empêcher tout déplacement angulaire entre le cercle d'encageage et la carrure, celle-ci doit être dans l'art antérieur, munie d'un ou plusieurs trous recevant autant d'ergots de la pièce-support, ou de vis dans le cas du document précité. Le problème des cotes intérieures de la carrure, qui doivent s'adapter au cercle d'encageage reste donc entier.Although the internal machining operations of the middle part are simplified by the interposition of the casing circle, there remain difficulties which have never have been satisfactorily resolved; in particular, to prevent any angular displacement between the casing circle and the middle part, this should be in the prior art, provided with one or more holes receiving as many lugs of the support piece, or screw in the case of the aforementioned document. The problem of inner dimensions of the middle part, which must adapt to the casing ring remains therefore whole.

L'invention se propose de remédier à cet inconvénient par les moyens décrits dans la partie caractérisante de la revendication 1.The invention proposes to remedy this drawback by the means described in the characterizing part of claim 1.

Le caractère élastomère du matériau venant dans l'intervalle entre le cercle d'encageage et la carrure permet de s'affranchir des contraintes, précédemment très strictes, en matière de cotes d'usinage intérieur de la carrure. Les cotes extérieures du cercle d'encageage posent moins de problèmes car cette pièce est en général moulée à part. Cependant, la précision qui était jusqu'alors requise dans le profil intérieur de la carrure était source de problèmes qui n'ont jamais été résolues de façon satisfaisante.The elastomeric character of the material coming in the interval between the circle casing and the middle allows to overcome constraints, previously very strict, in terms of interior machining dimensions of the middle. The odds of the casing circle pose fewer problems because this part is usually molded separately. However, the precision that was previously required in the interior profile of the middle was a source of problems which never have been satisfactorily resolved.

Dans l'invention, les éventuelles variations dimensionnelles de la carrure sont compensées par l'élasticité du matériau élastomère. In the invention, the possible dimensional variations of the middle part are compensated by the elasticity of the elastomeric material.

Dans une forme particulière de réalisation de l'invention, le matériau élastomère est surmoulé dans l'intervalle compris entre le cercle d'encageage et la carrure. Cette forme permet une réduction du nombre de pièces intervenant dans la fabrication du garde-temps. Le surmoulage consiste à amener sous pression un matériau dans une cavité, qu'il remplit entièrement avant de durcir, par exemple par polymérisation, tout en acquérant ou conservant des propriétés élastomères. On distingue, dans la technologie du surmoulage, l'injection, le transfert ou la compression, qui sont des techniques connues en soi.In a particular embodiment of the invention, the material elastomer is overmolded in the interval between the casing circle and the build. This shape allows a reduction in the number of parts involved in the manufacture of the timepiece. Overmolding consists in bringing under presses a material into a cavity, which it completely fills before hardening, for example by polymerization, while acquiring or retaining properties elastomers. We distinguish, in overmolding technology, injection, transfer or compression, which are techniques known per se.

Dans une forme particulière de réalisation de l'invention, il peut être avantageux d'insérer, à l'intérieur de l'intervalle, ces éléments élastomères dont chacun est de dimensions adaptées à la portion de l'intervalle qui le reçoit.In a particular embodiment of the invention, it can be advantageous to insert, within the interval, these elastomeric elements each of which is of dimensions adapted to the portion of the interval which receives it.

Ceci est particulièrement utile lorsque certaines portions de l'intervalle sont de forme complexe. La technique du surmoulage peut bien entendu, et sans sortir du cadre de la présente invention, s'appliquer de façon complémentaire à cette insertion ou assemblage d'éléments élastomères.This is particularly useful when certain portions of the interval are of complex shape. The overmolding technique can of course, and without going out of the framework of the present invention, to apply in a complementary manner to this insertion or assembly of elastomeric elements.

Dans une forme particulière de réalisation de l'invention, l'étanchéité procurée au garde-temps par le matériau concerne simultanément plusieurs éléments par lesquels l'eau risque de s'infiltrer. Il s'agit en particulier de la jonction entre le fond et la carrure, de celle entre la tige de remontoir et la carrure, et de celle entre la glace et la carrure.In a particular embodiment of the invention, the seal provided to the timepiece by the material simultaneously concerns several elements by which water may infiltrate. This is in particular the junction between the back and middle, from the one between the winding stem and the middle, and from the between the glass and the middle.

Dans une forme particulière de réalisation de l'invention, le matériau surmoulé est une matière plastique ou formulation de caoutchouc spéciale qui présente des propriétés d'auto-adhérisation. Ces propriétés lui permettent d'adhérer parfaitement à la face interne de la carrure et au cercle d'encageage, procurant ainsi une très bonne étanchéité.In a particular embodiment of the invention, the overmolded material is a special plastic or rubber formulation that has self-adhesive properties. These properties allow it to adhere perfectly to the inner face of the middle part and to the casing circle, providing thus a very good seal.

D'autres avantages de l'invention apparaítront dans la description détaillée qui suit, illustrée par le dessin dans lequel :

  • la figure 1 est une coupe partielle d'un garde-temps, objet de l'invention;
  • la figure 2 montre le même garde-temps mais avec le fond enlevé de la carrure;
  • la figure 3 représente une coupe partielle du fond.
Other advantages of the invention will appear in the detailed description which follows, illustrated by the drawing in which:
  • Figure 1 is a partial section of a timepiece, object of the invention;
  • Figure 2 shows the same timepiece but with the back removed from the middle part;
  • Figure 3 shows a partial section of the bottom.

Le garde-temps représenté au dessin est une montre 1 comprenant une carrure 2, un cercle d'encageage 3 et un fond 7. Dans le cercle d'encageage viennent, respectivement dans les secteurs 6 et 5, a mouvement 4 et un cadran. Sur la figure 1, une tige de remontoir vient dans a logement 10, comprenant un bourrelet d'étanchéité circulaire 12. Le matériau élastomère surmoulé 9 remplit tout l'intervalle compris entre le cercle 3, la carrure 2, et la tige venant dans le logement 10. Du côté extérieur, le logement 10 débouche dans une noyure de couronne 11 excavée dans la carrure 2.The timepiece shown in the drawing is a watch 1 comprising a middle part 2, a casing circle 3 and a bottom 7. In the casing circle come, respectively in sectors 6 and 5, with movement 4 and a dial. On the Figure 1, a winding stem comes in a housing 10, comprising a circular sealing bead 12. The overmolded elastomeric material 9 fills the whole interval between the circle 3, the middle part 2, and the stem coming into the housing 10. On the outside, the housing 10 opens into a recess of crown 11 excavated in the middle part 2.

La figure 2 montre une coupe angulairement décalée, par rapport à la coupe de la figure 1, de la carrure 2. C'est ainsi que l'orifice 13 du logement 10 est en dehors du plan de coupe. La figure 2 montre l'emplacement 6 du mouvement 4, ainsi que l'emplacement 8 du fond 7. Le cercle 3 comprend une cavité 14 destinée à recevoir un ergot du mouvement 4, cet ergot est destiné à rendre solidaire le mouvement 4 du cercle 3.Figure 2 shows a section angularly offset, relative to the section of Figure 1, the middle part 2. This is how the orifice 13 of the housing 10 is in outside the cutting plane. Figure 2 shows the location 6 of movement 4, as well as the location 8 of the bottom 7. The circle 3 includes a cavity 14 intended to receive a lug of movement 4, this lug is intended to make united movement 4 of circle 3.

On voit que la matériau élastomère 9, dans la figure 1, réalise l'étanchéité aussi bien entre le fond 7 et la carrure 2 qu'au niveau du logement 10, grâce au bourrelet 12.It can be seen that the elastomeric material 9, in FIG. 1, also makes the seal well between the back 7 and the middle part 2 as at the housing 10, thanks to the bead 12.

Les figures 1 et 2 montrent un épaulement 15 du cercle 3, noyé dans le matériau élastomère 9. Cet épaulement rend solidaires, après surmoulage, le cercle 3 et le matériau élastomère 9.Figures 1 and 2 show a shoulder 15 of the circle 3, embedded in the elastomeric material 9. This shoulder makes integral, after overmolding, the circle 3 and the elastomeric material 9.

Le fond 7 représenté à la figure 3 vient s'enclipser sur la partie inférieure du matériau élastomère 9, grâce à un cran 16.The bottom 7 shown in Figure 3 snaps onto the bottom of the elastomeric material 9, thanks to a notch 16.

L'étanchéité de la glace est réalisée, dans l'exemple décrit, par d'autres moyens non représentés. Cependant, on peut très bien concevoir que le matériau élastomère 9 ait une forme se prolongeant vers le haut, jusqu'à rejoindre un réhaut venant au-dessus du secteur 5, pour assurer également l'étanchéité de la glace.The glass is sealed, in the example described, by other means not shown. However, one can very well imagine that the material elastomer 9 has a shape extending upwards, until it joins a flange coming above sector 5, to also seal the ice cream.

Les propriétés d'auto-adhérisation du matériau élastomère 9 lui permettent de rendre parfaitement solidaires le cercle 3 et la carrure 2, en supprimant les contraintes de forme intérieure de cette carrure 2. Au moment du surmoulage, on peut éviter de coller la tige venant en 10 en l'enduisant d'un fluide approprié.The self-adhesive properties of the elastomeric material 9 allow it to make the circle 3 and the middle part 2 perfectly united, by removing the internal shape constraints of this middle part 2. At the time of overmolding, it is possible to avoid sticking the rod coming in 10 by coating it with a suitable fluid.

On conçoit que dans certains cas, il peut être préférable de constituer le matériau élastomère 9 par assemblage de divers éléments, chacun venant dans une portion de l'intervalle entre le cercle 3 la carrure 2, le logement 10 et éventuellement le fond 7.It is understood that in certain cases, it may be preferable to constitute the elastomeric material 9 by assembling various elements, each coming in a portion of the interval between the circle 3 the middle 2, the housing 10 and possibly the bottom 7.
