Definitions

the present invention relates to a method according to the preamble of claim 1.
the invention proposes to remedy this drawback by the means described in the characterizing part of claim 1.
the possible dimensional variations of the middle part are compensated by the elasticity of the elastomeric material.
the material elastomer is overmolded in the interval between the casing circle and the build.
This shape allows a reduction in the number of parts involved in the manufacture of the timepiece.
Overmolding consists in bringing under presses a material into a cavity, which it completely fills before hardening, for example by polymerization, while acquiring or retaining properties elastomers.
injection, transfer or compression which are techniques known per se.
the overmolding technique can of course, and without going out of the framework of the present invention, to apply in a complementary manner to this insertion or assembly of elastomeric elements.
the seal provided to the timepiece by the material simultaneously concerns several elements by which water may infiltrate. This is in particular the junction between the back and middle, from the one between the winding stem and the middle, and from the between the glass and the middle.
the overmolded material is a special plastic or rubber formulation that has self-adhesive properties. These properties allow it to adhere perfectly to the inner face of the middle part and to the casing circle, providing thus a very good seal.
the timepiece shown in the drawing is a watch 1 comprising a middle part 2, a casing circle 3 and a bottom 7.
a winding stem comes in a housing 10, comprising a circular sealing bead 12.
the overmolded elastomeric material 9 fills the whole interval between the circle 3, the middle part 2, and the stem coming into the housing 10.
the housing 10 opens into a recess of crown 11 excavated in the middle part 2.
Figure 2 shows a section angularly offset, relative to the section of Figure 1, the middle part 2. This is how the orifice 13 of the housing 10 is in outside the cutting plane.
Figure 2 shows the location 6 of movement 4, as well as the location 8 of the bottom 7.
the circle 3 includes a cavity 14 intended to receive a lug of movement 4, this lug is intended to make united movement 4 of circle 3.
the elastomeric material 9, in FIG. 1 also makes the seal well between the back 7 and the middle part 2 as at the housing 10, thanks to the bead 12.
Figures 1 and 2 show a shoulder 15 of the circle 3, embedded in the elastomeric material 9. This shoulder makes integral, after overmolding, the circle 3 and the elastomeric material 9.
the bottom 7 shown in Figure 3 snaps onto the bottom of the elastomeric material 9, thanks to a notch 16.
the glass is sealed, in the example described, by other means not shown.
the material elastomer 9 has a shape extending upwards, until it joins a flange coming above sector 5, to also seal the ice cream.
the self-adhesive properties of the elastomeric material 9 allow it to make the circle 3 and the middle part 2 perfectly united, by removing the internal shape constraints of this middle part 2. At the time of overmolding, it is possible to avoid sticking the rod coming in 10 by coating it with a suitable fluid.
the elastomeric material 9 by assembling various elements, each coming in a portion of the interval between the circle 3 the middle 2, the housing 10 and possibly the bottom 7.
