Definitions

  • Boxes are also known, the bezel of which, in two pieces, is constituted by an element independent of the glass and the middle part and comprises a ring made of transparent material, on the reverse of which time signs are hollow molded and are filled with light phosphorescent material. , so as to appear by contrast with a dark protective varnish, applied to the reverse of said ring, which thus constitutes the annular dial of the watch (CH-A-323'978).
  • glass in this third known box, which has an opaque part at its periphery, but a part which is independent of it and which is mounted for itself on the box.
  • glass can only be made from relatively soft material.
  • the state of the art also contains watch cases in which the glass and the middle part, made of hard materials, having the same coefficient of thermal expansion, form a body for the operations of casing the movement (FR-A-2'397 ' 668).
  • the box of the type defined by the preamble of claim 1 as well as by the characteristic of claim 1 avoids the aforementioned drawbacks, while considerably widening the range of appearances which it is possible to give to the box.
  • a watch dial, time signs, counters, hands, calendar rings
  • it is, in fact, mainly the part of the box usually occupied by independent, conventional glasses, which determines the appearance of '' a wrist watch to wear.
  • To make it a piece of jewelry, as it should be for a quality watch it is therefore on this part of the box that we must operate, and this, by providing ornamental elements other than a dial.
  • the support for these ornamental elements is the opaque frame fixed to the transparent plate of the glass.
  • the middle, the bottom and the transparent plate of the glass can be produced in series, as large as the number of terminations. requested for the visible side of the box.
  • the opaque frame fixed to the transparent plate of the glass, which constitutes the visible face of the box and gives it its appearance.
  • the frame in question is easy to manufacture.
  • Claims 3 and 4 define two equally advantageous methods of fixing the opaque frame to the transparent plate of the glass.
  • the adhesives offered on the market produce long-lasting adhesions, more than sufficient in this case.
  • they are perfectly transparent and, under certain conditions, easy to make, they dry very quickly.
  • the protective effect such as that exerted by glass, in the special embodiments defined by claim 5, has already been used extensively in watch cases. In this case, it allows you to decorate the visible face of the box using ornamental elements, even very delicate, without the risk of deteriorating the latter, since they are under the protection of a particularly hard element. .
  • the ornamental elements of the glass may also consist of thin layers applied by vacuum spraying, but the frame fixed to the transparent plate of the glass makes it possible to make them massive, as defined in the claim. 6. They can even constitute the entire peripheral part of the glass (claim 4).
  • the ornamental elements will preferably also be made of sapphire, but colored and not transparent.
  • the glass defined by claim 8 has the advantage of being suitably protected against impact and the risk of catching on foreign bodies.
  • the box shown in Figs. 1, 2 and in the upper half of FIG. 3 has a generally rectangular shape. It includes a bottom shell 1, of the same shape, which has a circular cylindrical recess 2 for the movement 3 of the watch. Dial 4 also has a rectangular shape, but its corners are rounded.
  • the back 1, furnished with the movement 3 and the dial 4, is fitted into a middle part 5 to which it is fixed by screws 6, as seen in the drawdown in phantom in FIG. 1.
  • the seal between the two parts of the box is ensured by a gasket 7.
  • clearances 8 Fig.
  • the middle part 5 has a flat upper face 11 and, along the edge of its central opening 12, a projection 13.
  • the shape of the opening 12 corresponds to that of the case and the dial, as shown in FIG. 3.
  • the glass 14 of this box is composed of three pieces made of transparent synthetic corundum, commonly called sapphire and the faces of which are polished.
  • Fig. 2 shows a blank, which includes a rectangular upper plate 15, a central plate 16, smaller, whose shape corresponds exactly to that of the opening 12 of the middle part 5, and a frame 17, of the same thickness as the plate central 16, the external dimensions of which can be equal to or greater than those of the upper plate 15 and the opening of which is larger than the central plate 16.
  • This central plate 16 and the frame 17 are each glued to each other under the upper plate 15, using an adhesive which does not alter the transparency of the corundum.
  • a groove 18 appears on the back of the glass 14, between the central plate 16 and the frame 17, which forms a heel of the glass 14.
  • the upper edge of the glass 14 is then cut in bevels 19, 20, 21 (Fig. 3) extending over the entire height of the upper plate 15 and over part of the heel 17 (Fig. 1).
  • the underside of the plate 16 is then masked and a layer 22 of a few hundred angstroms is deposited on the walls and the bottom of the groove 18 as well as under the heel 17 by vaporization under vacuum, so as to make these parts opaque. of the glass 14. Since the faces of the glass 14 thus metallized are polished, the deposit 22 appears shiny through the glass.
  • this deposit 22 which will give the part of the face of the box, surrounding the transparent central zone of the glass 14, its final appearance.
  • the glass 14 is put in place by engaging its central part 16, furnished with a cuff 23, by force in the opening 12 of the middle part 5, until the bottom of the groove 18 and the heel 17 rest respectively on the projection 13 and the face 11 of the middle part 5.
  • the part of the upper plate 15 of the lens 14, extending between the central plate 16 and the heel 17 does not undergoes a stress after the establishment of the glass 14, and, on the other hand, a fault between the heel 17 of the glass and the middle part 5, the height of the projection 13 is exactly equal to the thickness of the central plate 16 and the heel 17.
  • the upper face of the latter is entirely masked by the deposit 22, as is the case in conventional boxes, comprising a fixed bezel on the middle.
  • a titanium plate 24, of a shape similar to the visible part of the dial can be glued to the center of the glass 14, in a recess on the outer face of the upper plate 15, for the aesthetic purpose of constituting a reminder of the appearance of the heel 17 while masking the axis of the needles and the crossing of these.
  • the central part of the obverse of the glass 25 is not flat. Facets 26 are cut in this part of the glass 25 according to a trunk of a tetragonal pyramid. If a plate 27 is housed in a recess in the center of the glass, as in the first embodiment, the facets 26 may extend to the edge of this plate or even over part of it, the pyramid n 'being then truncated only in the middle of the plate 27, as seen at 28 in FIG. 3.
  • Fig. 4 shows a third embodiment, which also only affects glass.
  • this embodiment it is no longer a transparent frame which constitutes the heel of the glass 29, but opaque elements 30.
  • Two first opaque elements 30 can thus be glued under the upper plate 31 of the glass 29, along the lateral sides of the latter, opposite "3 h" and “9 h ", and two other opaque elements, of the same material as the first or made of a different material, can then be glued between the ends of the first two opaque elements, along the short sides of the glass.
  • These elements 30 can be metallic or ceramic; they can also be made of colored synthetic corundum.
  • a transparent plate 32 is also glued under the central part of the plate 31 and an opaque layer 33 is vaporized under vacuum in the groove 18 of the glass 29. It can extend under the elements 30 where it does not however have any influence on the appearance of the box, unless the elements 30 still have a certain translucency.
  • the transparent part of the glass could extend only above the groove formed on the back of the glass. Opaque, metallic, ceramic or colored corundum elements would then no longer be glued under this transparent part, but against its edge.
  • the bevels, such as 19, 20, 21, cut along the edge of the glass, would then preferably start from the joint between the transparent and opaque parts of the glass. Thus, this joint would no longer appear in the middle of a facet of the glass, as in the first embodiment, but along an edge, where it would be less apparent, due to the contrast existing between the vaporization of the throat and opaque elements glued against the transparent part of the glass.
  • this has the advantage of ensuring a constant, well-defined bonding surface, between the opaque elements and the transparent part of the glass, whatever inclination the bevels at the edge of the glass can to have.
  • Fig. 5 shows an embodiment which differs from the previous ones only in the shape of the obverse of the glass.
  • the part of the external face of the glass 34 comprised between the bevels 19, 20, 21, has facets 35 parallel to the direction "6 o'clock" - "12 o'clock" of the box.
  • the two bevels 19 on the short sides of the box extend at 19a in a part of the central zone of the glass.
  • the ornamental elements, carried by the frame fixed to the transparent plate of the glass are fine or semi-precious stones, such as for example lapis lazuli, the eye- cat or tiger's eye, opal, coral, malachite, etc.
  • the transparent frame 17 of the first embodiment (Fig. 1) is made thinner than the central plate 16 of the glass 14 and a fine stone frame is glued under this heel, so as to arrive flush of the central part of the glass intended to engage in the opening 12 of the middle part 5 of the box.
  • the central part of the fine stone, cut to form the opening of the frame, is not lost; it can in particular garnish the dial of the watch.
  • the dial and the box then have the same veins and the same colors, since the decorations of the dial and the box both come from the same plate of fine stone.
  • the fine stone, glued under the heel of the glass is not only protected, but its visible side has more shine, is more shiny, than those of bare stones. For this reason, a fine stone plaque that we would like to see in the center of the glass, to hide the axis of the needles and their crossing, would be buried in a recess arranged not on the obverse, but on the back of the glass.
  • the pieces of the box and the glass have exactly the same shapes and dimensions in all the examples described.
  • the parts of the box and the glass blanks can be mass produced. Only the vaporization of the throat of the glass and the nature of the decorations of the heel of the glass change from one model to another in the same series. For sprays, simply expose the glasses for the required time.
  • the massive ornamental elements they can be prepared in parallel with the manufacture of the other parts of the box. Their final bonding to the transparent part of the glass, which is carried out last, is an easy operation, which does not risk extending the delivery times unexpectedly.
  • a glass of synthetic corundum has the advantage of constituting a shield making the visible face of the box practically unalterable, it is clear that the invention is not limited to such glasses. These could be made in whole or in part from other materials, for example tempered mineral glass or even synthetic resin or organic material.
