Definitions

  • the present invention relates to a watch case according to the preamble of claim 1. More specifically, this invention relates to a watch case comprising a middle part of precious metal produced by electroforming, in which casing means can be introduced to support the others watch components. In particular, this invention relates to the problem of fixing the middle part with the fitting means.
  • the case is constituted by the middle part, the bezel and the back, these elements being able to be separate or on the contrary integrated.
  • Such watches are well known.
  • the shoulders are produced by electroforming which, instead of being massive, are hollowed out. This simultaneously reduces the weight and the price of the housing.
  • Casing means for example a casing circle, are then fixed on this case and maintain the movement of the watch and the other internal components.
  • These fitting means can be made of a more economical material than the metal of the middle part.
  • the hollowed-out space between the middle part and the casing ring remains hollow, which makes it possible to reduce the weight of the watch.
  • none of these models offers a satisfactory solution to the problem of fixing the middle part with the fitting means.
  • Precious metal machining operations are generally very expensive. We therefore seek to obtain a middle which can be manufactured with a minimum of machining operations, if possible only by electroforming. On the other hand, we also aim to simplify as much as possible the manufacture of the casing circle, which is manufactured by conventional machining operations the number of which it is desired to reduce.
  • Patent CH79203 describes a thin housing screwed onto the casing ring directly by its internal peripheral surface. A large diameter thread must therefore be machined on the precious metal case as well as on the casing ring. This solution is therefore not suitable for watches to be manufactured at low cost.
  • Patent CH667966 teaches to screw the housing, or cap, onto the circle, or body by means of several screws passing through the bottom and the body of the box and engaged in threaded holes in the housing. This solution therefore requires tapping in the housing and drilling in the body of the box. This solution is therefore not suitable for watches that must be produced at a minimum price.
  • Patent CH343939 uses the same principle of screwing the case, but in order to save material on the case suggests screwing the casing ring on four studs pierced with a tapped hole.
  • these studs must also be made of gold.
  • separate means must be provided to fix the casing circle with the case and to assemble the back of the watch. This solution is therefore quite complicated.
  • Patents CH427658 and GB2157029 describe a housing in which screws pass through the thin metal housing and are engaged in threaded holes in the casing ring. This avoids performing tapping operations in the noble metal of the housing.
  • the screw heads appear on the lateral surfaces of the housing, which is generally considered to be unsightly.
  • threads must be machined in the casing ring.
  • Patent CH681414 constitutes a variant in which the case is screwed to the casing means from below the watch, which makes it possible to hide the screws.
  • the case must be extended under the underside of the watch, which leads to a waste of precious metal.
  • through holes for the screws must be drilled through the precious metal case, as well as threads in the casing means, which also increases the cost of the watch.
  • Patent EP379974 describes a housing hollowed out towards the inside of the box.
  • the housing is held by at least three pots shaped to position the components axially in the housing.
  • the fitting means are therefore held by their periphery by means of the studs. This solution therefore requires the use of studs to be specially manufactured, and does not allow very easy assembly or disassembly of the watch case.
  • Patent application EP626625 describes a housing constituted by a peripheral body, of noble metal, removably attached to a central body of inexpensive material.
  • the peripheral body, or case is held on the central body, or circle, thanks to synthetic inserts inside the middle. These inserts have bulges which correspond to grooves machined in the circle. This method of attachment is therefore not suitable for shoulders whose recess remains empty. In addition, grooves must be machined in the circle. Additional assembly means are also necessary for fixing the bottom to the circle.
  • the object of the present invention is therefore to propose a watch which does not have the drawbacks mentioned of the solutions of the prior art.
  • an object of the present invention is to provide a watch comprising a case with a thin-walled middle part, especially made of precious metal, requiring a minimum of machining operations, in particular drilling and tapping, for fixing the fitting means.
  • the object of the present invention is to reduce all the costs of manufacturing the middle and the casing circle, and simplify the assembly of these two elements.
  • Another object is to provide a light watch, requiring in particular a minimum of precious metal, but having sufficient rigidity.
  • Gold boxes deserve this designation only under certain conditions set by national laws.
  • the middle part or the case must have a fine gold content in accordance with the indication of the title mentioned.
  • the back if it is separate from the middle part, must partially cover it.
  • Another object of the invention is therefore to propose a construction of a watch case which, if it is made of gold, deserves the designation and the hallmark of the gold box.
  • a watch case comprising a hollowed-out middle and provided with thin walls, guaranteeing a minimum weight.
  • the middle part is manufactured by electroforming. Its internal face is mainly concave. It supports attachment means for a bracelet. A back is assembled to the middle.
  • the fitting means which serve to hold the internal components of the watch, can be introduced into the case, leaving a recess between the internal face and the fitting means.
  • the casing means are made of a less expensive material than the middle part and are held inside the case by compression between a lower bearing surface and an upper bearing surface, the lower bearing surface being defined by a portion of the inner face of the base and the upper bearing surface being defined by a portion of the inner face of the middle part.
  • the fitting means are introduced or extracted from the middle by disassembling the base.
  • the upper bearing surface is defined by a portion of the internal face of the telescope.
  • the casing means are introduced or extracted from the middle by disassembling the bezel, and / or by disassembling the base in the variants with removable bottom.
  • the fitting means are fixed to the middle without using assembly means passing through the fitting means. This avoids drilling or tapping through the fitting means.
  • FIG. 1 illustrates a profile section of a watch case. Only the elements essential for understanding the invention proper have been shown.
  • the watch case 1 comprises a middle part 2 made of metal, preferably of noble metal such as gold, silver or platinum.
  • the middle may have different shapes and structures depending on aesthetic considerations and in order to limit the weight of raw material.
  • the walls of the middle part are as thin as the strength of the material allows.
  • the thin walls of the middle part are curved in order to improve the resistance to mechanical impact.
  • the internal face 20 of the middle part 2 may include ribs 23. These ribs may for example have a honeycomb structure, or another motif adapted to the particular shape of the middle part.
  • the middle part is manufactured by electroforming operations to obtain a thinness of the walls compatible with the target price range.
  • the internal face 20 of the middle part is hollowed out and therefore has a mainly concave profile.
  • a bracelet 4 is fixed by any known means to the middle part, for example by means of horns 3. If necessary, the middle part includes reinforcements which are not shown near the horns.
  • the middle part has an opening in the base through which the various components of the watch, in particular the movement 11, can be introduced.
  • Casing means 5 are introduced through this opening, which make it possible to support the watch components.
  • these means, or similar means are also referred to as the container, the reinforcement structure, the body of the box, the circle, the frame or the casing ring, casing or movement holder.
  • these fitting means 5 consist essentially of a one-piece element having approximately the shape of the part 5 in the figures, this is generally called a fitting circle 5.
  • the box also has a bottom 6 which closes the opening in the lower part of the middle part.
  • the bottom is fixed to the casing circle 5 by screws 60.
  • a bottom gasket 10 prevents water infiltration between the casing circle 5 and the bottom 6.
  • the dial 14 is visible through the glass 7 supported by the flange 8.
  • a glass seal 9 is kept compressed between the glass 7, the casing ring 5 and the housing 2. To avoid compressing the glass seal in two directions, that -ci could also be disposed only between the casing circle 5 and the periphery of the glass 7.
  • the casing ring 5 When assembling the watch, the casing ring 5 is first introduced with the other components of the watch through the bottom of the case, and abuts against an upper bearing surface 21 formed by the part upper side of the inner face 20 of the middle part 2.
  • the bottom 6 is then put in place and fixed by means of screws 60 passing through the bottom and engaged in rings 24 provided with an internal thread and produced by electroforming in the middle.
  • the internal lateral walls of the rings 24 form a guide surface 26 facilitating the introduction of the casing circle 5 into the middle part 2.
  • the casing circle 5 is inserted between the rings 24.
  • Other configurations of the means of guidance can of course be imagined.
  • the casing circle 5 is thus firmly compressed between the upper bearing surface 21 and a lower bearing surface 22 defined by a portion of the internal face of the bottom 6. No drilling or tapping is necessary in the circle. casing 5.
  • the middle part 2 of precious metal can be entirely produced by electroforming.
  • FIG. 2 illustrates a second embodiment of a watch case 1 according to the invention.
  • the threaded ring 24 is replaced by a column 25 provided with an internal thread.
  • the guide surface 26 is thus larger, which makes the insertion of the casing circle extremely easy.
  • these columns give the middle an additional rigidity, at the cost, however, of an additional precious metal for the middle.
  • FIG. 3 illustrates a third embodiment of a watch case according to the invention.
  • the bottom 6 is provided with an integrated thread 61 corresponding to an equivalent thread on the middle part 2.
  • the bottom is therefore fixed by direct screwing after the introduction of the casing circle 5.
  • the circle d the casing 5 is firmly compressed between the upper bearing surface 21 and a lower bearing surface 22 defined by a portion of the internal face of the bottom 6.
  • the manufacture of the base may however be more costly, especially since not being of uniform thickness the base cannot be produced simply by stamping operations.
  • the bottom as well as the middle are entirely made by electroforming, which avoids having to use cutting tools to make the threads.
  • FIG. 4 illustrates a fourth embodiment of a watch case according to the invention.
  • the base 6 is mounted with a notch on the hollowed middle part 2. It will be noted that the bottom partially covers the middle part, and that the fixing notch also provides a guide surface 26 for the casing circle.
  • FIG. 5 illustrates a variant of the embodiment of FIG. 2, but in which instead of balusters 25 integrated into the housing, removable balusters 27 are used.
  • the balusters 27 can advantageously be made of a more economical material than the middle part 2, for example steel.
  • the posts are fixed by screws 28 passing through the upper face of the middle part, and engaged in a thread inside each post. Other methods of fixing the balusters 28 to the housing are naturally conceivable.
  • the posts are detachably fixed, and not welded or glued, for example, so that the watch case can deserve the name gold box, which is in most legislations only issued if all pieces attached to the box are made of gold.
  • FIG. 6 illustrates a variant of FIG. 5, in which each screw 28 - column 27 assembly is replaced by a single part 29, provided with a slot in its upper part and an internal thread in its lower part.
  • the part 29 is firstly threaded through the corresponding opening in the upper part of the middle part 2.
  • the casing circle is then introduced with the other components of the watch.
  • the bottom 6 is then placed, which is held by screws 60 also making it possible to hold the parts 29.
  • FIG. 7 illustrates a variant of the invention without threading.
  • the casing ring 5 is maintained between the upper bearing surface 21 and the base 6, itself fixed to the middle part 2 by screws passing through both the bottom and the middle part, and retained by corresponding keys 62.
  • This solution is particularly economical, since no thread is necessary.
  • the placement of the key during the assembly of the watch can represent a difficulty. It is possible to temporarily put the key in place before the insertion circle is introduced, and to maintain it during assembly by means of a point of glue for example.
  • FIG. 8 illustrates an alternative embodiment of FIG. 1, in which the watch case is further provided with a removable bezel 15.
  • This bezel can for example be made of a metal other than the middle part 2, for example in platinum while the middle is gold. It is also possible to make the bezel in the same metal as the middle part, but to give it a different aesthetic appearance by means of an appropriate surface treatment.
  • the bezel 15 is first introduced into the middle part 2, then the casing circle 5 which comes to rest against an upper bearing surface 21 constituted by a portion of the internal face of the bezel 15
  • the bottom 6 is then screwed onto the middle part 2 by means of the screws 60, and comes to compress and maintain the casing ring 5 by means of the bearing surface 22.
  • This variant comprising a removable bezel 15 could naturally be adapted to housings comprising a bottom 6 screwed directly, as in FIG. 3, or fixed to the notch as in FIG. 4.
  • the bezel 15 is held only by pressing against the middle part 2. It is naturally possible to fix the bezel to the middle part, for example by screwing or notch fixing.
  • FIG. 9 illustrates a watch case in which the base 6 is integrated into the middle part 2, and therefore produced by the same electroforming operation.
  • the casing ring 5 is introduced by the upper face of the watch and bears against the bearing surface 22 formed by a portion of the internal face of the back 6. The circle is then held in place by the mounting of the bezel 15, which offers another upper bearing surface 21.
  • the bezel is itself fixed to the housing 2, in this example by screws 16 engaged in rings 30 provided with an internal thread, and offering a surface of guide 26 facilitating the introduction of the casing circle 5.
  • Other means of fixing the bezel to the housing are naturally possible, for example any of the means described in connection with Figures 1 to 8 for fixing the bottom to the housing.
  • fitting means can, according to the variants, be made from several elements possibly composed of different materials, for example steel and / or synthetic material.
