Definitions
- the present invention relates to a device for waterproof fixing of a crystal to a watch case, comprising a generally cylindrical annular seal in compressible material having an annular projection internal to the upper end of this annular seal, a annular groove formed on the edge of the ice in which this annular projection is engaged, a surface lateral lateral, formed on the upper part of the middle to receive the lower part of the face internal of said annular seal, the base of which abuts against a scope and a bezel adjusted around said joint by compressing it radially.
- waterproof fastening devices hard glass such as toughened glass or sapphire, in which the hard glass is fixed in a ring made of a soft material relative to the glass of watch as well as with respect to the metal of the box which it should be fixed.
- This ring is usually in organic glass such as Plexiglas.
- a fastening device of this kind is described in CH 519 193 in which the glass is housed in a ring in organic glass, the whole then being introduced by hunting in a housing of a middle-bezel, the deformations after hunting being absorbed by the ring in organic glass which also seals fixation.
- a false bezel can be attached to the middle part to hide the glass fixing ring.
- the fixing ring is housed in a annular groove formed in the edge of the glass in order to not to go beyond its perimeter and thus not to be visible.
- Such a fixing device requires placing under stress of the annular seal surrounding the glass beforehand to the fixing of this assembly in an opening of the build.
- the removal of this set poses big problems since the prestressed joint is completely embedded in the the middle and the sapphire or tempered glass cannot be distorted.
- the same surface of the bezel is used to tighten the joint around the ice and around the lateral surface of the build.
- the force required to remove the telescope can vary in a ratio of 1 to 4.
- the position of the telescope after hunting can change slightly from room to room, thereby repercussions on the compression of the annular seal.
- injection points can only be located in a visible area or in a contact area and are therefore bothersome in both cases.
- the object of the present invention is to remedy, by part, to the aforementioned drawbacks.
- the subject of this invention is a device waterproof fixing of a crystal on a watch case according to claim 1.
- seal annular is no longer compressed radially uniformly over full height, but only two separate compression zones are formed, one at the level of the ice, the other at the adjustment surface, adjacent to the edge upper part of the middle. So when chasing the bezel, its base does not compress the upper part of the joint, avoiding the risk of forming a bead which is placed between the bezel and the middle.
- the part of the annular seal located between the face lower part of the glass and the upper edge of the middle part is not or very little compressed radially, thus avoiding the risk of being deformed in the free space separating the middle part.
- the radial compressions induced in the two tightening zones are not necessarily the same, but can be adapted independently in each zone.
- the injection points of the seal can take place, especially in the case of seals opaque, in the portion of its external face located between the bulge of the base of the joint and the part of the face inner of the bezel with the smallest diameter. After mounting, this portion is indeed hidden by the bezel and also constitutes a non-functional area of the joint, since it is not in contact with any surface of the glasses.
- the present invention provides substantial improvements which are appreciable in particular during assembly operations as well as level of maintenance, since disassembly is found facilitated by less dispersion of the values of lens removal forces, without compromising efficiency tightness, on the contrary.
- FIG. 1 to 4 we recognize a watch glass 1, a seal annular 2 of generally cylindrical shape, the upper part a middle 3, as well as a bezel 4 driven around of the external face of the annular seal 2.
- This ice which is preferably made of a hard material such than tempered glass and more advantageously a sapphire crystal, is machined in a plate.
- the watch glass slice 1 is delimited by two portions of different diameters, one of large diameter 1a, the other of smaller diameter 1b, adjacent to the underside of the glass 1.
- a groove annular 1c separates these two portions 1a and 1b.
- the annular seal 2 has a projection internal annular 2a adjacent to its upper edge. This projection 2a penetrates into annular groove 1c of ice 1, while the small diameter portion 1b penetrates slightly in the inner face of the annular seal 2. To facilitate understanding, on all the figures, the portions deformed of the annular seal 2 have been shown in mixed lines in their undistorted state.
- this annular seal 2 is engaged around a lateral interlocking surface 3a formed at the upper end of the middle part 3 and situated substantially at the same level as the flange 3b.
- the basis of this surface lateral socket 3a has an annular groove 3c.
- a bulged heel 2b protrudes symmetrically from the side and the other of the internal, respectively external, lateral faces, at the base of the annular seal 2.
- the part of this heel bulging 2b protruding inside the annular seal 2 engages in the annular groove 3c on the lateral face socket 3a.
- the internal lateral face of the bezel 4 has two cylindrical portions, one lower portion 4b more large diameter and a smaller upper portion 4a diameters.
- the diameter of the lower portion 4b more large diameter of the inner side face of the telescope is greater than the diameter of the external lateral face of the seal annular 2, but less than the outer diameter of its heel bulging 2b, while the diameter of the upper portion 4a is less than the diameter of the external lateral face of the ring seal 2.
- the joint is made of polyamide 6.6 with a modulus of elasticity is between 2100 and 3000 MPa
- it can be made of polyamide, PBT or POM in particular, whose elastic modulus is between 1000 and 3000 MPa.
- the variant illustrated in FIG. 5 does not differ from the embodiment described above only by the form of the annular seal 2 'and more precisely by the shape of the heel bulging 2'b. Unlike the bulged heel 2b, it does not protrudes only on the outer lateral face of the annular seal 2 ', leaving the internal lateral face of this joint annular 2 'cylindrical, from the base of the annular projection internal 2 'has engaged in the annular groove 1c of the window 1, all the way down.
- This variant has the advantage of facilitating demolding of the annular seal 2 'during its injection, while retaining the system for anchoring this joint to the middle. This variant also makes it easier to assemble and disassembly of the annular seal 2 '.
- the injection points of the seal 2 or 2 ' will be located opposite part 4b of the telescope 4 having the largest internal diameter and on the face outer of the annular seal 2 or 2 'located between the heel 2b or 2'b and the top of part 4b of the telescope 4. So these injection points are not visible and are not located in a contact area of the annular seal 2 or 2 '.
