Definitions

  • the invention relates to a waterproof watch case intended to receive a movement of small thickness and comprising a middle-bezel on which a glass is mounted in a sealed manner, a bottom mounted notch on the middle and a casing frame supporting the movement. .
  • the present invention proposes to overcome the drawbacks mentioned above by presenting a new construction provided with the means which appear in the claims.
  • Figure 1 shows how the timepiece object of the invention is assembled.
  • the crystal 2 and the dial 3 are separated by the flange 4 forming part of the middle part 1.
  • the movement 5 is held in place by a first flange 6 of a casing frame 7.
  • This frame also carries a second flange 8 engaged in a groove 9 made in the inner part of the middle part.
  • the rim 8 is centered in the groove 9 by the shoulder 21.
  • An elastic bandage 10 surrounds the frame 7 surmounted by its second rim 8 and is also engaged in the groove 9.
  • the bottom 11 is engaged in the middle part 1 by means of two hooks 12 and 13 and when the watch is assembled, the bandage 10 takes the form of a rectangle as shown in the figure.
  • the first long side of this rectangle surrounds the frame 7 and the second long side covers the joint 14 formed by the middle part 1 and the bottom 11. The tightness is ensured by the short sides of the rectangle which are pressed respectively against the groove 9 and the inner wall of the bottom 11.
  • the height of the bandage 10 when it is not yet mounted in the part, slightly exceeds (0.1 to 0.2 mm) the height of the void formed by the middle part and the bottom, to allow, at the time of assembly, the crushing of the bandage and the assurance of a good seal.
  • Figure 2 for its part uses the same components which have been discussed in connection with Figure 1 and also shows how the control rod of the watch is mounted.
  • This rod 15, capped with a crown 16 passes through the casing, the elastic bandage 10, the frame 7 and is then coupled to the mechanism of the movement 5.
  • An orifice 17 is drilled in the bandage 10 whose diameter is slightly smaller than the stem diameter.
  • Figure 3 which is a section along the line A-A of Figure 2, shows that the middle part 1 and the bottom 11 are each provided with an opening 18, 19 in the form of U whose open branches look at each other.
  • the orifice 17 of the bandage 10 is located in the extension of the U-shaped openings.
  • the casing frame 7 may be made of metal while it will advantageously be made of plastic if we are dealing with a shaped box.
  • the elastic bandage 10 will be removably secured to the frame in the manner of a tire mounted on a rim.
  • the elastic bandage as described makes it possible to considerably reduce the height of the watch since it consists of a simple and single surround of rectangular shape which takes up very little space and ensures both a watertight mounting of the base on the middle and a sealed passage of the control rod.
  • this construction makes it possible to provide an external draft 20 around the periphery of the bottom, which contributes to giving the assembled part an even thinner appearance.
