Definitions

  • the present invention relates to a watch case comprising a middle part, a case back, a movement housed in the box, a dial surmounting the movement and an assembly which can be rotated with respect to the middle part and to the dial, said assembly comprising a bezel. having an inner annular shoulder, a crystal fixed to the bezel by means of a first lining and an annular member forming a flange, a second lining being interposed between the bezel and the middle part.
  • the bezel flange carries graduations rotating opposite other graduations carried by the fixed dial, these graduations being used as slide rule for example, it is advantageous to enlarge the dial beyond the diameter of the movement to increase reading accuracy and facilitate the application of graduations on the dial and the flange.
  • the box of the invention is characterized in that it comprises a casing circle disposed inside the middle, first means for fixing the movement in the casing circle and second means for securing the circle to the middle part, said circle having an annular flange disposed inside the middle part resting on said shoulder to hang said assembly on said middle part.
  • Figure 1 is a top view of the watch case according to the invention.
  • the needles 43 are mounted on the dial 6, for example.
  • Horns are attached to the middle to attach the strands 41 and 42 of a bracelet.
  • a rotating bezel 1 provided with a knurling 19.
  • graduations 45 and 46 are shown here only in part.
  • FIGS. 2 and 4 The sections of Figures 2 and 4, produced respectively along lines II-II and IV-IV of Figure 1, show that the case has a middle part 8, a bottom 13, a movement 7 housed in the box, a dial 6 surmounting the movement 7.
  • An assembly 3 comprising a bezel 1 having an inner annular shoulder 20, a lens 2 secured to the bezel by means of a first gasket 4 and an annular member forming a flange 5, can be driven in rotation relative to the middle and the dial. Between the bezel and the middle part is pinched a second lining 9 which seals the case.
  • the lining 9 is arranged between two coaxial cylindrical surfaces, one limiting 22 a portion of the bezel and the other 23 a portion of the middle part.
  • Figures 2 and 4 show above all what makes the peculiarity of the present invention, namely that the box has a casing circle 10 - 11 has inside the middle part 8, this circle having an annular flange 21 resting on the shoulder 20 of the bezel 1 for hooking or retaining the rotating assembly 3 on the middle part 8.
  • the ring of the cited document is transformed here into a casing circle which not only serves to retain the bezel but also to support for movement.
  • Figure 4 also shows that first means are provided for fixing the movement 7 in the circle 10 - 11 these means consisting of flanges 16 and screws 17 in the construction taken here as an example.
  • FIG. 2 also shows that second means 31 are used to secure the circle 10-11 to the middle part 8.
  • Figure 2 shows that the middle part 8 has in its lower part a flange 24 extending towards the center of the box. On this flange 24 rests the casing circle 10, 11.
  • the second means mentioned above are screws 31 placed vertically and passing through bores 25 made in the flange 24 and screwed into threads 26 made in the circle 11.
  • the construction provides a bottom 13 provided with projections 27 which, once the bottom in place under the middle part 8, prevent the screws 31 from being unscrewed, even if these screws have been released.
  • the bottom 13 is screwed at 14 to the middle part 8. It could also be fixed there.
  • Figures 2 and 4 like Figure 5 which will be discussed below, show a dial 6 whose diameter is larger than the overall diameter of the movement 7 which is favorable for the reasons mentioned in the preamble of this description.
  • the same figures show that the movement 7 is fitted by the top of the casing circle 11, this circle having a shoulder 50 against which is supported a thread 51 of the movement 7.
  • Figures 2 and 4 show that the casing circle is made in two parts, either a first inner part 11 comprising the shoulder 50 against which the movement 7 is pressed and a second outer part 10 comprising the annular flange 21.
  • the largest possible diameter of the dial 6 is limited by the inner diameter of the circle 10.
  • the flange 5 can also overlap the dial 6 in order to make the slot between the flange and the dial invisible and also in order to simplify construction.
  • the assembly of the box with the movement it traps is done in the following order. From the top of the bezel 1, taken alone, the outer part 10 of the casing circle is mounted until the annular collar 21 of the circle comes to bear on the shoulder 20 of the bezel. Mount the flange 5 in the bezel 1 and place the trim 4 on the flange. The glass 2 is forced into the trim 4. The assembly 3 is obtained intended to rotate on the middle part 8, this assembly additionally carrying the outer part 10 of the casing circle, this part remaining free to move in rotation on this together.
  • the movement 7 is introduced from above into the inner part 11 of the casing circle until the thread 51 of the movement 7 abuts on the shoulder 50 of the circle. The movement 7 is fixed to the circle 11 by means of the screws 17.
  • the internal part 11 of the circle is introduced, with its movement, inside the external part 10 of the circle and from below this external part. These two parts of the circle are fixed to each other by means which will be discussed below.
  • the assembly thus formed is introduced through the top of the middle part 8 until the hoop 11 presses against the flange 24 of the middle part.
  • the circle 11 is fixed to the middle by means of the screws 31.
  • the box is closed by means of the screwed bottom 13 by interposing a lining 15 between the bottom and the middle.
  • FIG. 5 Another method of fixing the two parts of the casing circle is shown in FIG. 5.
  • the external part 30 has elastic zones 53 each provided with a spout 54 which is hooked into a notch 55 formed in the internal part 11.
  • the outer part 30 will advantageously be made of plastic.
  • the present invention also allows, if necessary, to use a movement whose dial is smaller or equal in diameter to the diameter of the movement.
  • This embodiment is shown in Figure 6.
  • the movement 7 is fitted from below a casing circle 40 which can be made in one piece with its annular flange 21 and a shoulder 28 against which is supported a net 29 of the movement.
  • FIG. 3 shows an embodiment of the rotating bezel in which is mounted, between the rotary assembly 3, furthermore in accordance with the description above, and the middle part 37 a device for unidirectional rotation of said assembly.
  • This device comprises a ring 33 in which springs are lifted which act on notches 34 known as rack and affixed to the bezel 38.
  • This ring 33 is retained and oriented by at least one lug 35 trapped in the housing 36 formed in the middle part 37
  • a detailed example of this construction is described in the document CH-A-631 592.
  • the device is advantageously placed outside the perimeter of the lining 9. An interior position would require protection of the movement against the dust which is released during of the friction of the spring on the notches 34.
  • the device is covered by the roof 32 which presents the bezel. The device is used particularly for diver's watches.
