Description
<Desc/Clms Page number 1>
Remontoir étanche L'objet de la présente invention est un remontoir étanche comprenant un anneau d'étanchéité moulé et soumis à un serrage entre deux parties du remontoir.
Ce dernier est caractérisé par le fait que l'anneau susmentionné est conçu et disposé de façon que ses bavures de moulage se trouvent dans une zone de l'anneau où elles ne sont pas soumises au serrage susmentionné.
Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention. La fig. 1 en est une coupe axiale.
La fig. 2 est une coupe agrandie d'un détail.
Les fig. 3, 4 et 5 montrent des variantes de celui-ci.
Le remontoir représenté comprend un pendant 1 destiné à être fixé à la boîte et une couronne 2 dans laquelle doit se visser la tige du remontoir. Entre les surfaces la et 2a du pendant et de cette couronne est serré l'anneau d'étanchéité 3, fait en matière plastique élastique et obtenu par moulage. 4 est une rondelle fermant le logement de cet anneau.
Celui-ci est représenté en fig. 2, avant son emploi. Sa section est limitée par un demi-cercle et par deux parties droites ; il a été moulé dans un moule en deux parties, construit de façon que les bavures de moulage, exagérées en fig. 2, se trou- vent en 5. La fig. 1 le montre en place, ayant été déformé par serrage entre les surfaces la et 2a ; mais les bavures de moulage se trouvent en 5, hors de ces surfaces, dans une zone où elles ne sont pas soumises au serrage susmentionné ; elles ne peuvent donc pas produire sur ces surfaces de petits bourrelets nuisibles à l'étanchéité.
La fig. 4 montre une variante de l'anneau de la fig. 2, dans laquelle on a ménagé un petit angle a facilitant l'éloignement des deux parties du moule. La fig. 3 est une autre variante dans laquelle les bavures de moulage sont disposées en 5a, et la fig. 4 montre cette même variante dans laquelle on a aussi prévu un petit angle a de dégagement.

Waterproof winder The object of the present invention is a waterproof winder comprising a molded sealing ring subjected to clamping between two parts of the winder.
The latter is characterized by the fact that the aforementioned ring is designed and arranged so that its molding burrs are in an area of the ring where they are not subjected to the aforementioned clamping.
The accompanying drawing represents, by way of example, an embodiment of the object of the invention. Fig. 1 is an axial section.
Fig. 2 is an enlarged section of a detail.
Figs. 3, 4 and 5 show variations thereof.
The winder shown comprises a pendant 1 intended to be fixed to the case and a crown 2 in which the stem of the winder must be screwed. Between the surfaces 1a and 2a of the pendant and of this crown is clamped the sealing ring 3, made of elastic plastic material and obtained by molding. 4 is a washer closing the housing of this ring.
This is shown in fig. 2, before its employment. Its section is limited by a semi-circle and by two straight parts; it was cast in a two-part mold, constructed so that the molding burrs, exaggerated in fig. 2, are located at 5. FIG. 1 shows it in place, having been deformed by clamping between surfaces 1a and 2a; but the molding burrs are located at 5, outside these surfaces, in an area where they are not subjected to the aforementioned clamping; they cannot therefore produce on these surfaces small beads which are harmful to the seal.
Fig. 4 shows a variant of the ring of FIG. 2, in which a small angle has been made to facilitate the removal of the two parts of the mold. Fig. 3 is another variant in which the molding burrs are arranged at 5a, and FIG. 4 shows this same variant in which a small clearance angle a has also been provided.
