Definitions
- the present invention relates to the assembly of the constituent elements of a watch case and it relates more particularly to a method for manufacturing a watch case element comprising on the one hand a crystal, and on the other hand a rigidly secured fixing member to the latter, as well as the element obtained by this process and a watch case comprising this element.
- the present invention proposes a new method for producing a watch case element comprising a crystal and a fixing member subject to the latter, which allows an easy production of this fixing member, in various materials, which are themselves easy to machine if necessary, and this in any desired shape.
- the latter also proposes watch case elements manufactured according to the aforementioned method, as well as a watch case incorporating them.
- a watch case element consists of a lens 1, to which a fixing member 2 is attached.
- a metal covering 3 is provided, the purpose of which is to ensure masking of the fastening member 2, and to guarantee better resistance of the assembly.
- the glass 1 can have any desired shape
- the fixing member 2, constituting an annular heel for fixing the glass can have a corresponding shape.
- this heel cannot extend over the entire periphery of the glass, but only, for example, along two opposite sides of a glass of rectangular or square shape.
- FIG. 2 there is shown a glass 4, also provided with metal coating zones 5, at which are fixed fixing pads 6 extending perpendicular to the plane of the glass and forming fixing members.
- the fastening members 2 or 6 are not manufactured separately, then assembled with ice in an often imperfect manner, as in the prior art, but formed directly on the respective metallic coatings by a process for molding a molten material.
- the material of the fasteners is compatible with, and has a good affinity for the material of the metal coating, the choice of the material of the fasteners is wide, and most of the metal alloys commonly used in the watchmaking or precision mechanics can be used.
- the fixing members are made of a metal of the zinc, tin, copper, gold type, in the pure or alloyed state.
- the metal known under the name zamac which is an alloy of zinc, aluminum, copper and magnesium, or other types of alloys as well.
- Eutectic alloys are particularly interesting, since the eutectic composition of an alloy leads to a lower melting temperature.
- the coatings used at the junction between the fixing members and the glass panels can be deposited according to various known methods, such as for example by vacuum metallization or galvanic deposition.
- These coatings may have several layers, for example a chromium undercoat ensuring adhesion to the glass and masking of the fixing member, to which is superimposed a second layer of a material similar to that of the fixing members. to ensure the attachment of the metal during molding.
- a chromium undercoat ensuring adhesion to the glass and masking of the fixing member, to which is superimposed a second layer of a material similar to that of the fixing members. to ensure the attachment of the metal during molding.
- an outer layer of zinc will be used to secure a zamak fastener or gold to secure a gold fastener.
- a glass 20, 20 ′ is shown in view from below, provided with a peripheral heel 21, 21 ′ which has a variable width so as to be slightly deformable in a radial direction, for example for absorb the stresses during the cooling of the material forming the heel, or those due to differences in coefficients of thermal expansion between the ice and the heel.
- This variable width can be obtained by providing narrowing in the general shape of the heel, as well as openings 22 (fig. 3), or even by means of notches 22 '(fig. 4) left alternately on each lateral face of the heel. during molding. Of threads 23, 23 'allow to fix the member 21, 21, in a watch case middle.
- FIG. 5 illustrates yet another variant of the invention, in which inserts 27, constituted for example by threaded steel studs, are partially embedded in a fixing member 28 at the time of its production, for allow it to be anchored in another element of a watch case. Furthermore, it can be seen that the fixing member 28 can be produced on an inclined lower part 29 of the lens 30, with the interposition of a coating 31.
- the fixing member 33 comprises two adjacent zones, separated by the dotted line 34 and made of different materials.
- a first layer adjacent to the coating 35 of the glass 36 can be made of tin to ensure good adhesion with the coating 35, while the zone situated below this layer can be made of a bronze having better qualities. mechanical.
- the line 34 does not correspond to an abrupt separation between the two zones, but to a region of interpenetration of the two neighboring materials.
- the external part of the fixing member 33 is provided with a cap 37 which can be made of a hard material, or of a precious metal such as gold. This cap, which can therefore have a protective or decorative function can be, for example, attached to the member 33 after its formation, or even already inside the mold used for the manufacture of this member.
- FIG. 7 is shown schematically an installation allowing the production of the watch case elements of FIGS. 1 or 2.
- the crystal 1 is placed between two parts 8, 9 of an injection mold, the part 9 comprising a channel 10 the shape of which corresponds to that of the fixing member to be formed.
- An opening 11 allows this channel to communicate with the outside and to fill it with a molten metallic material.
- the ice 1 can be heated inside the mold, and all known methods of molding molten material can be used, for example injection under pressure by centrifugation, or molding in a maintained oven. at low pressure, in order to lower the melting point of the materials used.
- FIG 8 there is shown another aspect of the invention, according to which a fixing member 13 produced as indicated above, is used not only to secure a lens 14 to the upper part of a component 15 of a watch case, such as a middle or a bezel, but also to seal the assembly.
- the fixing member 13 the constituent material of which can be chosen so as to be able to closely match the external shape of a housing 16 formed in the part 15, is forcibly engaged in this housing, and its support on the lateral surface of the housing 16 is further improved by a tension ring 17 disposed radially inside the annular fixing member 13.
- the metallization 18 of the underside of the crystal extends well heard beyond the tension ring 17.
