Abstract

The sealed watch crown has an inner part designed in such a way as to ensure sealing in the region of the tube of the frame, and the outer part of the crown. The two parts are obtained by a complete covering with rubber or silicone material. This guarantees a perfect sealing of the watch with respect to dust and water in the region of the crown and frame tube since the seal is no longer effective only over a small portion of the length of the tube, but over all of it. The surface of the outer part of the rubber crown makes it possible to obtain, by adding colorants during the vulcanisation, crowns with the entire range of colours. This technique guarantees the stability of the colours over time, in contrast to the methods currently known such as paint, coloured oxides, etc which deteriorate after the watch has been used for a certain period of time. An outer metal covering is provided, attached to the silicone moulding. <IMAGE>

- Le brevet Suisse CH-A-473'419- Swiss patent CH-A-473,419

La caractéristique de ce brevet réside dans le fait que pour permettre une étanchéité au niveau couronne - tube, il est prévu de faire un moulage soit un ou deux bourrelets sur l'intérieur de la couronne qui fonctionne sur un tube lisse, ou sur un tube prévu avec une ou deux rainures. La matière synthétique employée pour effectuer le montage est un matériau plastique qui n'a pas lespropriétées élastiques présentées par l'elastomére selon notre revendication qui permet de garantir une étanchéité en ayant la face intérieur de la couronne lisse ainsi que celle du tube.The characteristic of this patent resides in the fact that to allow a seal at the crown - tube level, it is planned to make a molding either one or two beads on the inside of the crown which works on a smooth tube, or on a tube provided with one or two grooves. The synthetic material used to carry out the assembly is a plastic material which does not have the elastic properties presented by the elastomer according to our claim which makes it possible to guarantee a seal by having the internal face of the smooth crown as well as that of the tube.

- Le brevet Suisse CH-A-321'578- Swiss patent CH-A-321,578

La caractéristique de ce brevet réside dans le fait que pour permettre une étanchéité au niveau couronne - tube, il est prévu de mouler une matière plastique à l'intérieur d'une "calotte" revêtement métallique. Les matériaux employés pour cette réalisation sont des matières plastique synthétique du type polyamide, nylon, résines vinyliques, plexiglas ou polystyrol, qui n'ont pas les propriétés élastiques présentées par l'elastomère selon notre revendication. La technique de réalisation est également différente puisque il n'existe pas d'âme métallique à l'intérieur du moulage de ce type de produit.The characteristic of this patent resides in the fact that in order to allow sealing at the crown - tube level, provision is made to mold a plastic material inside a "cap" of metallic coating. The materials used for this embodiment are synthetic plastic materials of the polyamide, nylon, vinyl resins, plexiglass or polystyrol type, which do not have the elastic properties presented by the elastomer according to our claim.

- Le brevet français FR-A-2312819- French patent FR-A-2312819

La caractéristique de ce brevet réside dans le fait que l'étanchéité de ce montage et prévu seulement contre les poussières et que ce type de système est compatible pour de l'appareillage et non pour des dimensions horlogères. A l'encontre de la revendication de cette demande de brevet qui assure l'étanchéité contre l'eau.The characteristic of this patent resides in the fact that the tightness of this assembly and provided only against dust and that this type of system is compatible for apparatus and not for horological dimensions. Contrary to the claim of this patent application which seals against water.

La Fig. no. 1 du dessin annexé est une vue de profil avec coupe à échelle agrandie représentant à titre d'exemple une forme d'exécution selon la technique actuelle, comme, de couronne' étanche.Fig. no. 1 of the accompanying drawing is a side view with a section on an enlarged scale showing, by way of example, an embodiment according to the current technique, like, of a 'sealed crown'.

La Fig. no. 2 est une vue de profil avec coupe à échelle agrandie représentant à titre d'exemple une forme d'exécution de l'objet de l'invention.Fig. no. 2 is a side view with section on an enlarged scale showing, by way of example, an embodiment of the object of the invention.

Des couronnes étanches (Fig. 1) du type susmentionné sont connues en soit. Elles présentent l'inconvénient que le joint 0-Ring (1) qui assure l'étanchéité ne travaille que sur une faible partie de la longeur du tube de la boîte (2), et que la bague de retenue du joint (3) laisse la possibilité à des agents extérieurs tels que sueur, eau salée... etc., de pénétrer jusqu'au niveau de celui-ci, ce qui provoque une détérioration prématurée du joint et permet de ce fait des infiltrations d'eau.Watertight crowns (Fig. 1) of the above-mentioned type are known per se. They have the disadvantage that the 0-Ring seal (1) which ensures the sealing works only on a small part of the length of the tube of the box (2), and that the retaining ring of the seal (3) leaves the possibility of external agents such as sweat, water salt ... etc., to penetrate to its level, which causes premature deterioration of the seal and therefore allows water infiltration.

La couronne selon l'invention (Fig. 2) est caractérisée par le fait que la partie qui assure l'étanchéité (1) avec le tube de la boîte (2) est une revêtement de matière souple et compressible qui adhère parfaitement sur toute la profondeur intérieur de l'âme de la couronne (3) tout en exerçant une tension continue sur toute la longeur fonctionnelle du tube de la boîte (2).The crown according to the invention (Fig. 2) is characterized in that the part which seals (1) with the tube of the box (2) is a coating of flexible and compressible material which adheres perfectly over the entire interior depth of the core of the crown (3) while exerting a continuous tension on all the functional length of the tube of the box (2).

Offrant ainsi la possibilité d'obtenir un revêtement extérieur de même matière (la) que revêtement intérieur (1) ou d'obtenir une coiffe métallique (4) sur le revêtement extérieur (la).Thus offering the possibility of obtaining an external covering of the same material (la) as internal covering (1) or of obtaining a metallic cap (4) on the external covering (la).

Le'but de l'invention est donc de remédier aux inconvénients susdits des couronnes counues en fournissant dans une disposition du type susmentionné (Fig. 2), toutes les garanties nécessaires afin d'assurer une étanchéité parfaite dans le temps, en éliminant les vides produits par le joint 0-Ring et sa bague de retenue et en garantissant l'étanchéité non plus sur une faible partie de la longueur de tube 2, mais sur la totalité de sa partie fonctionnelle.The aim of the invention is therefore to remedy the above-mentioned drawbacks of crowns by providing, in an arrangement of the aforementioned type (FIG. 2), all the guarantees necessary in order to ensure perfect sealing over time, by eliminating voids. produced by the 0-Ring seal and its retaining ring and guaranteeing sealing no longer on a small part of the length of tube 2, but on the whole of its functional part.

La technologie employée pour réaliser une couronne étanche selon l'invention du type Fig. 2 est donc une technologie de moulage par compression, et pour garantir une adhérance parfaite du caoutchouc (1-la) sur l'âme de la couronne (3) qui est réalisé en acier inoxidable, celle-ci doit au préalable subir un traitement de surface bien spécifique.The technology used to produce a waterproof crown according to the invention of the type shown in FIG. 2 is therefore a compression molding technology, and to guarantee perfect adhesion of the rubber (1-la) to the core of the crown (3) which is made of stainless steel, this must first undergo a treatment of very specific surface.

La vulcanisation de la gomme employée est réalisée en une seule fois ce qui permet de garantir une même structure moléculaire sur la totalité du recouvrement intérieur et extérieur de l'âme de la couronne.The vulcanization of the gum used is carried out at one time which guarantees the same molecular structure over the entire interior covering and outside of the soul of the crown.

La réalisation de ce type de couronne selon l'invention peut s'effectuer selon deux procédés de fabrication différents:

  • a) - soit par moulage par compression
  • b) - soit par moulage par injection
The production of this type of crown according to the invention can be carried out according to two different manufacturing methods:
  • a) - either by compression molding
  • b) - either by injection molding

Pour ces deux types de fabrication il est indispensable que les parties métalliques sur lesquelles viennent adhérer le caoutchouc subissent une suite de traitement bien spécifiques soit:

  • - un décapage dans un bain d'acide
  • - un dépôt par giclage de PRIMER 1
  • - un séchage à température ambiante
  • - un dépôt par giclage de PRIMER 2
For these two types of manufacturing, it is essential that the metal parts to which the rubber adhere undergo a very specific treatment sequence either:
  • - pickling in an acid bath
  • - a spray deposit of PRIMER 1
  • - drying at room temperature
  • - a spray deposit of PRIMER 2

a) Moulage par compressiona) Compression molding

Les âmes des couronnes (3) ayant subi les préparations mentionnées ci-dessus sont introduites dans un moule à l'intérieur duquel est déposé une certaine quantité de mélange de gomme naturel, la vulcanisation est effectuée a haute pression et à haute température.The cores of the crowns (3) having undergone the preparations mentioned above are introduced into a mold inside which is deposited a certain amount of natural gum mixture, the vulcanization is carried out at high pressure and at high temperature.

A ce moment le mélange se transforme en caoutchouc vulcanisé lui donnant toutes les caractéristiques élastomériques qui lui sont propres, tandis que les PRIMER 1 et 2 se mélange avec la gomme et l'âme métallique (3) en formant ainsi une union moléculaire permanente.At this time the mixture is transformed into vulcanized rubber giving it all the elastomeric characteristics which are specific to it, while the PRIMER 1 and 2 mix with the rubber and the metallic core (3) thus forming a permanent molecular union.

Une fois la couronne démoulée celle-ci subit un traitement d'ébavurage mécanique à basse température.Once the crown is demolded, it undergoes a mechanical deburring treatment at low temperature.

La surface de la partie extérieure de la couronne qui est en caoutchouc, permet d'obtenir par additif de colorants au moment de la vulcanisation des couronnes de toute la gamme couleurs.The surface of the outer part of the crown, which is made of rubber, makes it possible to obtain, by additive, dyes at the time of vulcanization of crowns of the entire color range.

Cette technique garantit la tenue des couleurs dans le temps, contrairement aux procédés actuellements connus tels que peinture, oxides de couleurs, etc. qui après un certain temps d'utilisation de la montre se détériorent.This technique guarantees the color fastness over time, unlike currently known processes such as painting, color oxides, etc. which deteriorate after a certain period of use.

b) Moulage par injectionb) Injection molding

Les âmes de couronnes ayant subi les préparations mentionnées ci-dessus, sont introduites et positionnées dans un moule à l'intérieur duquel on injecte à basse pression et à haute température du silicone liquide qui se catalyse et se transforme en élastomère élastique.The core cores having undergone the preparations mentioned above, are introduced and positioned in a mold inside which is injected at low pressure and at high temperature liquid silicone which catalyzes and transforms into elastic elastomer.

La conjonction chimique entre l'âme de la couronne (3) et le corps de la couronne en silicone catalisé (1-la) est obtenu pendant le moulage par le mélange des PRIMER 1 et 2 avec le silicone et l'âme métallique en formant ainsi une union moléculaire.The chemical conjunction between the core of the crown (3) and the body of the catalyzed silicone crown (1-la) is obtained during molding by mixing PRIMER 1 and 2 with the silicone and the metallic core, forming thus a molecular union.

Le revêtement métallique extérieur (4) de la couronne subit également le même traitement de préparation et vient introduit mécaniquement sur la couronne en silicone.The outer metal coating (4) of the crown also undergoes the same preparation treatment and is introduced mechanically onto the silicone crown.

La conjonction chimique entre le revêtement métallique (4) et le corp de la couronne en silicone cataysé (la) est obtenu à basse pression et à haute température par le mélange des PRIMER 1 et 2 avec le silicone et le revêtement métallique extérieur qui forme ainsi une union moléculaire.The chemical conjunction between the metallic coating (4) and the corpus of the catalyzed silicone crown (la) is obtained at low pressure and at high temperature by mixing PRIMER 1 and 2 with the silicone and the exterior metallic coating which thus forms a molecular union.
