Definitions

  • the present invention relates to a waterproof seal for a watch, type comprising a moving part in translation, like a crown of set time or a pusher, a piece secured to the box and a seal seal inserted between the movable part and the fixed part. More precise, the fixed and mobile parts have surfaces between which is interposed the seal.
  • the seal being generally ring-shaped with a section round. The quality of the seal thus obtained is a function of the structure of the parts and seal quality. In any case, if the seal pressure on the parts is insufficient, the risk is great to see the filling does not ensure the expected tightness.
  • joint comprises two lips interconnected by one of their ends, the other end being in contact with the surfaces of the fixed and moving parts, said lips being arranged so as to form between them a housing open to the outside of the box and in which is disposed an organ elastic applying the lips against the surfaces.
  • the seal although being a relatively low thickness, thus ensuring a quality seal thanks to the fact that the elastic member applies the lips against the surfaces of contact of the fixed and moving parts, thus generating a distinct pressure greater than that specific to the material constituting the seal.
  • the housing is open towards the outside of the box, when the box is subjected to an external pressure, the watch being for example diving in the water, the lips are applied with greater force against their contact surfaces.
  • the moving part is formed of a setting crown and the fixed part of a tube integral with the box.
  • the surfaces are cylindrical and coaxial with the ring.
  • the crown carries a ring defining a groove in which is disposed said seal whose housing is open on the ring. In this way, the seal is perfectly maintained in place, without affecting its working conditions.
  • the crown comprises a portion housed in the tube and provided with a radially extending cylindrical groove outward, and inside which is arranged the seal, his lips being respectively in support against the faces of the tube and the groove.
  • the moving part is a pusher and said piece fixes a tube integral with the box.
  • Contact surfaces, on which the lips support, are flat and parallel to each other, and perpendicular to the axis.
  • the surface of which the tube is provided is limited by flanges positioning it radially.
  • the seal shown in Figure 1 is intended to equip a box not shown in the drawing and which carries a rigidly fixed tube 10 and waterproof way to the wall of the box.
  • This tube passes through the box of part in part and opens at the same time towards the inside and the outside of box II has an outer cylindrical face 10a in its middle portion and has a conical portion 10b at its end opposite to that fixed at box. It is intended to allow the passage of a rod for controlling setting the time of the watch.
  • This function is provided by a crown 12 engaged on the tube 10 and capable of rotating about an axis A-A confused with the axis of the tube.
  • the ring 12 and the tube 10 define between them an open space at the same time towards the inside and the outside of the box which, if not closed, could allow impurities to enter.
  • the ring 12 is secured to a ring 13 fixed by gluing or welding, to through which the tube 10 is engaged. It is provided, in its portion central, a tapped hole 14 coaxial with the axis A-A and for receiving the rod setting time.
  • a groove 16, in which the tube 10 is engaged, surrounds the central portion of the crown 12.
  • the crown 12 comprises, in in addition, a cylindrical wall 18 whose inner face 18a extends concentrically to the tube 10 and to the central portion, forming between them a annular groove 20 partially closed box side by the ring 13. This the last houses a seal 22 advantageously rubber.
  • a circular clearance 21 made at the end of the inner face 18a of the 12 crown can receive the ring 13 from closing the opening annular 20 and maintain the seal 22 therein.
  • the seal 22 comprises two lips 22a and 22b connected to each other. the other by one of their ends and in contact respectively with the faces 10a and 18a, which are concentric.
  • the lips 22a and 22b define together a housing 24 in which is disposed an elastic member 26 in support against the walls of the housing and tending to apply the lips against the faces 10a and 18a.
  • the housing 24 is open towards the outside of the box, so that, if the watch is immersed in water, the pressure generated by it will tend to apply the lips 22a and 22b against the walls 10a and 18a, thus reinforcing the tightness.
  • the conical portion 10b of the tube 10 facilitates the setting in place of the ring 12 on the tube 10 and prevents the lip 22a from deformed.
  • the elastic member may be of the type of coil springs, as proposed by the seals marketed by the Bal Seal House (USA). he ensures that the seal is held in place, even though it only shows one thin.
  • FIG. tube 10 secured to the box and comprising an inner cylindrical face 10c, and a crown 12.
  • the latter is provided, in its engaged portion in the tube 10, a cylindrical groove 28 extending radially towards outside and provided with a cylindrical surface 28a concentric with the face 10c.
  • this groove is disposed the seal 22, whose lips 22a and 22b are respectively in abutment against the face 10c and the surface 28a.
  • the lips define a housing 24 in which is disposed a elastic member 26.
  • the housing 26 is open towards the outside of the box, so that if the watch is immersed in the water, the pressure of it tends to apply the lips against the surfaces contact of the tube and the crown.
  • the risk of deformation of the lip is avoided 22a during the introduction of the ring 12 on the tube 10, because the portion connecting the lips 22a and 22b is engaged in the tube 10 before the lips themselves. The latter can then slide without risk of wrap.
  • FIG. 3 represents a push-button for a watch provided with a pad according to the invention.
  • the box carries a tube 10 passing through from one side to the other and defining an axis A-A.
  • a pusher 30 is disposed on the tube 10. It comprises a cylindrical portion 30a engaged in the tube 10, an annular portion 30b surrounding the tube 10, these portions being interconnected by a portion 30c forming the support surface for pressure control.
  • the tube 10 is provided at its outer end with a delimited groove 10d radially by two flanges 10e and 10f and provided with a flat bottom.
  • a seal sealing 22 is disposed in the groove 10d, a lip 22a being in abutment against the inner surface of the portion 30c, the other 22b against the surface of the bottom of the groove 10d, these two surfaces being parallel to each other.
  • the lips form a housing 24 in which is disposed an elastic member 26.
  • the housing 24 is open towards the outside of the watch, so that if the latter is diving in water, the pressure it exerts tends to apply the lips against their contact surfaces.
  • the flanges 10e and / or 10f limit the space in which the gasket is arranged 22, but also provide a stop function, preventing a pressure too high on the pusher does not crush the elastic member 26.
  • the lips of the seal are in contact with either cylindrical surfaces (Figures 1 and 2) or with flat surfaces (Figure 3). It would also be possible to work the lips on surfaces however, the seal must be rotated in such a way that the housing 24 is open towards the outside of the watch.
  • seal 22 could be of a different material than the rubber. It must, however, have good flexibility, without as much risk of distortion.
  • the elastic member 26 could be made also in the form of a ring cut and folded, as described in the patent application WO2004046831 in the name of the applicant.
