Description

  

  Waterproof winder. The object of the present invention is a watertight winder for a timepiece comprising a package mounted on its stem in solidarity therewith and tightly fitted in the hole of the case, characterized in that said package is pressed. entrusts a support of:

   the rod by a ring freely adjusted on 7a, rod and in the -brou of the box and placed under the action of a spring supported against -la. crowned.



  The appended drawing represents, <B> by </B> by way of example, an embodiment of the watertight remon toir forming the subject of the invention.



  The trusted. 1 is an axial section thereof and FIG. 2 a section along the line II-II of the fié. 1.



  Referring to the drawing, 3 denotes the middle of a waterproof watch case pierced with a smooth winding hole 4, and of equal diameter everywhere. 5 designates a winding crown in a tarawd'ë hole of which the crown section 6 of a broken winding stem is screwed. On the rod 6 is mounted, integrally to the latter, a sealing package fitted in a leaktight manner in the hole 4.

   This package is composed of three washers 7 of compressible material separated from one another by intermediate washers 8 of non-compressible material, for example metal; the rons delles 8 have an outside diameter smaller than the diameter of the hole 4 so as to reduce the. rubbing of the package against the wall of the hole.

   The package is pressed against a shoulder 9 of the rod 6 by a metal ring 10, freely adjusted on the rod and in the hole and placed under the action of a blade spring 11, in the shape of a four-pointed star, resting on the bottom of a recess 12 made in the underside of the crown 5. The spring 11 is thus hidden from view from the outside.



  It goes without saying that the package could be fitted into the hole of a -Lobe forming part of the box instead of being fitted into a hole drilled directly in the caseband; it could consist of a different number of compressible and rigid washers, or be formed of a single compressible washer.
