Definitions

  • the present invention relates to a waterproof watch case intended to house an ultra-thin movement, closed on the side of the bezel by a mineral crystal.
  • the extra-flat box being subjected to the same stresses as a normal box, despite its small dimensions, it must resist these stresses and of course it must also be waterproof.
  • the sealing issue is also important because it is a quality to which the user has been accustomed in recent years and is not always willing to sacrifice this quality for the benefit of aesthetics.
  • the reduction in the dimensions of the box also requires the reduction in the dimensions of the seals since their housings must be reduced to prevent them from weakening the various parts of the container too much. It is of course desirable that these boxes can be made of a noble material such as gold, the resistance to deformation of which is lower than that of the metals usually used for the manufacture of watches.
  • One of the vulnerable elements of such a watch is the crystal which must be fixed to the middle part in a watertight manner.
  • the reduction in the thickness of the box naturally results in the reduction of the thickness of the ice, which is preferably mineral ice, which increases the flexibility of the ice.
  • the glass is fixed by gluing or welding on an inside or outside shoulder of the middle part or the ice is chased in such a shoulder.
  • French patent application No. 2,494,004 describes an ultra-thin waterproof watch case. The ice is stuck in a shoulder of the glasses.
  • the direct fixing of the glass to the middle of the bezel by gluing or welding has some drawbacks: Changing the glass is difficult and in this case it is necessary to undo the glue or weld joint of the old glass, remove the traces and glue or weld the new glass, thus subjecting the box to handling and efforts that could damage the middle of the bezel and possibly deform the box, especially if it is made of noble metal that is less resistant to stresses.
  • the glue or solder joint ensuring the fixing of the glass on the middle part can break when the case is subjected to stresses such as the pulling of the bracelet or a pressure on the glass or mounting constraints because the glass rests on a rigid surface which only deforms with the entire box. In the same way, a glass mounted on a notch on a middle part can be dismantled accidentally under the effect of such stresses.
  • the invention aims to remedy these drawbacks.
  • the watch case according to the invention is characterized in that the crystal is integral with a ring housed inside the middle, that a sealing gasket ensures the seal between the ring and the middle and that the glass is fixed by gluing or welding to the ring which is preferably metallic.
  • the advantages of this solution are as follows: As the glass is fixed by gluing or welding to a ring which does not come from one piece with the box, the glass can be changed easily by dismantling the box or not depending on the variant chosen as will be described later. Thus in the event of a change of the glass, neither the middle of the bezel nor the case in general is subject to stresses which can damage or deform it apart, of course, from the stresses of mounting. The glue or solder joint is not likely to break due to the stresses of the bracelet on the middle or a pressure exerted on the glass, given that the ring supporting the glass is a mobile support which can therefore deform or move.
  • the ring can slide relative to the middle part and not follow its deformation thus avoiding the risk of detachment of the glass.
  • the watch case is formed of three parts superimposed, one of which is the middle part of the bezel is arranged to contain the other two.
  • the fact that the middle part contains and surrounds the other two parts improves the reliability of the case.
  • the shape of the periphery of the movement holder which is housed in a shape complementary to the middle part ensures good fixing of the movement holder on the middle part. In the same way the back rests on the movement holder thus filling the fourth housing of the middle part.
  • the parts constituting the box are intimately assembled and are presented almost like a monocoque box.
  • the weakening of the middle due to the second and third shoulders is compensated by the complementary shapes of the periphery of the movement holder and the back which is assembled by screws screwed into the middle.
  • As the seal is ensured, as far as the bottom is concerned, with a lining housed in a groove for raising the bottom, there is no axial force on the bottom due to the lining, the force being mainly radial.
  • the fixing of the glass-ring assembly fitted into the middle of the bezel from above is ensured by the seal.
  • Different configurations of the sealing housing are provided, simultaneously ensuring the seal between the glass-ring assembly and the middle part of the bezel and the holding of the ice-ring unit in the middle part.
  • the watch case illustrated in FIGS. 1 to 3 comprises a middle part of the bezel 1, a movement holder 2 and a back 3 and a glass 4 bonded to a ring 5.
  • the middle 1 has three successive shoulders 6,7,8 arranged in the form of a staircase and delimiting four housings.
  • the first housing is provided for the glass 4 which is glued or welded around its periphery to a ring 5 of the same shape as the bezel.
  • the ring extends beyond the edge of the glass 4 by a part horizontal by which abuts against the first shoulder 6 of the middle part 1.
  • the movement holder 2 has on its periphery a skirt 9 extending downward and provided with a horizontal bearing 10 thus forming an L-shaped profile (view in radial section).
  • the movement holder 2 comes by its periphery to bear against the second 7 and third 8 shoulders of the middle part 1 and the recess wall 11.
  • the bottom 3 comes to bear, by a horizontal bearing 12, against the underside of the range 10 of the movement holder while the vertical wall of a raising 13 bears against the inner wall of the skirt 9.
  • a groove 14 at the base of the raising 13 forms with the wall of the skirt 9, the housing of a gasket. Screws 15 ensure the assembly of three parts of the box.
  • the ring 5 has on the external lateral surface an oblique part 16 forming with an oblique part of the second housing of the middle part and the movement carrier 2 an approximately triangular housing for a seal 17.
  • the base of the ring 5 bears against the dial 18 which is supported by the movement holder 2 and ensures its fixing.
  • the third shoulder 8 of the middle part 1 is deleted, the second shoulder 7 extending to the vertical wall of the third to make room for a radial projection of the movement holder provided with a cylindrical passage 20 through which the corrector rod 19 passes.
  • the box shape described is rectangular, but of course any other shape can be produced having the same technical characteristics.
  • the assembly of three parts of the box is ensured by four screws 15 placed at the four corners of the box at the places where the shoulder 8, and has the largest dimension (fig.3).
  • fig.3 the largest dimension
  • the housing of the seal 117 is formed between an oblique face 116 of the upper part of the lateral surface of the ring 105 and the vertical and horizontal wall of the middle part 101 to close to the telescope.
  • the ring 105 rests on the dial 118.
  • the lens 204 is fixed to a ring 205 comprising on its upper face a groove 223 forming, after the fitting of the lens-ring assembly, with the underside of the telescope a housing for the lining. sealing ring 217.
  • the ring 205 rests on its underside partially on a shoulder of the movement holder 202 and partially on the dial 218.
  • FIG. 6 shows another variant for which the lateral surface of the ice-ring assembly is conical and comes to fit inside the telescope, the wall of which has a corresponding inclination.
  • a groove 324 on the conical wall of the bezel forms with the ring 305 a housing for the seal 317.
  • the ring 305 rests as before on the dial 318 and a shoulder of the movement holder 302.
  • variants of Figures 4 to 6 are intended to represent mainly ... the structure of the glass-ring assembly and the housing of the seal, the rest of the structure of the box being able to conform to one or other of the solutions adopted by each manufacturer, for example using a bottom coming from '' a room with the movement holder etc.
  • FIG. 7 like those of FIGS. 8 to 10 are boxes of the monohull type the interlocking of the ice-ring assembly being done last and from the top of the box.
  • the box has a middle part 31 which seen from above has three successive shoulders to support the movement 32, the dial 33, and the ring 35 on which the crystal 34 is fixed.
  • the bottom is closed or can be provided with an opening for give access to the lower part of the movement without having to dismantle the watch entirely. such an opening can be closed on a bottom mounted to notch as shown in FIG. 8 or by screws or any other means.
  • the seal 37 is housed in a groove 36 of rectangular section of the vertical wall of the telescope.
  • the ice-ring assembly is introduced last, by pressing on the periphery of the glass.
  • the diameter of the lining is such that it squeezes the ring-glass assembly which is thus held and cannot accidentally come out of the middle part.
  • FIG. 8 presents as difference compared to that of FIG. 7, the shape of the section of the groove 46 which is here triangular and which makes it more difficult to accidentally disengage the ice assembly 44 ring 45 because when the lining is pulled on this assembly, because of the oblique face of the housing 46, tends to tighten this assembly more strongly.
  • Another difference compared to FIG. 7 is that the middle part is closed by a removable bottom 48 mounted on a notch.
  • the variant partially illustrated in FIG. 9 is, like that of FIG. 10, one of the preferred variants of watches of the monohull type since the crystal-ring assembly also includes a groove 56 of cross section similar to that of the middle part, thus ensuring better hold. of the ice-ring assembly by the trim.
  • the ring 65 of the variant of FIG. 10 has an L-shaped section.
  • the glass 64 being fixed on the inner surface of the ring 64 and the groove 66 is only made on the ring 65. It is obvious that the interior arrangement of the case can be different as regards, for example, the configuration of the shoulders of the middle part so the ring supporting the crystal can be directly in contact with the dial or an intermediate ring like that of FIG. 4.
  • the glass can come in one piece with the ring or it can be fixed by gluing or welding. It is possible, since the ring is preferably metallic, to deposit a metallic layer on the inner periphery of the glass and then weld it on the ring.
