Definitions

  • the present invention relates to a watch case formed by the assembly of an upper shell, at least part of which is transparent to reveal time display members, a lower shell and a middle disposed between the shells. and in the vicinity of their periphery, said shells and said middle defining an interior space in which takes place a movement.
  • Timepieces have already been described in which the movement is mounted in a box comprising two shells, at least one of which is made of transparent material, these shells being applied one against the other. This is particularly the case of the timepiece described in patent CH 110 141.
  • the shells are assembled by means of an expandable metal circle placed on the joint of the shells and enclosing the latter, such so that this join is no longer apparent once the circle is placed. This circle accentuates the outer contour of the watch and removes from it the lightness of appearance that it could have if said circle was absent or at least invisible.
  • the object of the present invention is to give the case the appearance of being thin, this impression being however even more accentuated than in the watch described in the patent.
  • the use of two shells, preferably made of sapphire, applied one against the other gives the watch case a new and unprecedented aesthetic appearance.
  • arrangements are made to retract the attachment points of the bracelet inside the box so that the bracelet emerges from the box without having to use horns or other visible hinges.
  • the middle part has upper and lower faces arranged to match the shape of the lower and upper faces respectively which the upper and lower shells to serve as their bearing surfaces and that said middle part is entirely confined inside said shells, the edges which they present being visible and substantially contiguous at least over part of their periphery.
  • FIG. 1 shows in perspective the essential parts of the watch case according to the invention.
  • This box has an upper shell 1 of which at least part is transparent to leave appear time display members, for example a dial 20 and hands 18, as shown in Figure 3.
  • the case also has a lower shell 2 and a middle part 3 disposed in the vicinity of the periphery of the shells .
  • the shells 1 and 2 and the middle part 3 define an interior space in which a movement takes place as referenced 17 in FIG. 3.
  • FIG. 4 which is a section at 9 o'clock in the assembled box
  • the middle part 3 has upper and lower faces arranged to match respectively the shape of the lower and upper faces which the upper shells 1 and lower respectively 2 to serve as their support surfaces.
  • Figure 4 also shows that the middle part 3 is entirely confined inside the shells 1 and 2 so that it in no way protrudes from the box.
  • Figure 2 which is an elevational view of the assembled box, we see that the middle part 3 does not appear at all and that the edges 11 and 12 of the shells 1 and 2 are visible and substantially contiguous to the less on part of their periphery, that is to say in places which have neither bracelet strands nor crown.
  • Figures 1 to 5 show a first embodiment of the invention in which, as also for the other modes described below, the middle part 3 comprises means for fixing the strands of a bracelet.
  • these fixing means comprise two housings 40 and 41 made in the middle part 3 and a bar arranged in each of the housings, only the bar 13 being shown in the figures.
  • the strand 4 of the bracelet As can be seen in Your figures 1 and 3.
  • the same figures show that the lower shell is provided with a cutout or notch 8. From the same way the strand 5, placed opposite the strand 4, emerges from the box by the cutout 9 shown in FIG. 1.
  • the box contains a movement 17 surmounted by a dial 20 and hands 18, the movement being fixed to the middle by conventional means not shown.
  • This movement includes at least one time-setting rod ending with a crown 10 ( Figures 2 and 5).
  • the crown is housed half in a notch 6 made in the upper shell 1 and half in a notch 7 made in the lower shell 2, as seen in Figures 1 and 2.
  • the control rod emerges from a hole 42 made in middle 3.
  • Figures 3 and 4 also show that in addition to the lower shell 2, the box has a bottom 14 secured to the middle part 3.
  • a seal 15 is interposed between the bottom and the middle part.
  • Figure 4 shows that the underside of the base 14 and the underside of the middle part 3 have a continuity solution so that the lower shell 2 can be fixed either on the bottom by means of a single central screw 19, or on the middle by means of a plurality of screws 26 shown in dotted lines in FIG. 4.
  • the lower shell 2 is first deposited, then the bottom 14. We can then take the movement out from underneath the box.
  • the upper shell 1 it is simply bonded to the upper face of the middle part, the bonding by itself ensuring the required seal.
  • FIG. 6 is a section at 6 o'clock in the box of the invention.
  • the bracelet fixing means consist of a boss 24 adjoining the middle part 3, or made in one piece with it, as shown in the figure.
  • This boss extends under the upper shell 1 and is provided with a hole 43 which receives a bar 44.
  • the ends of the bar emerge from the hole and each have a tapped blind hole 25 to receive a screw not shown.
  • the bracelet which is not shown in FIG. 6, surrounds the ends of the bar 44 around which it can pivot.
  • the lower shell 2 is provided with cutouts 45 in which the boss 24 and the bar 44 take place.
  • FIG. 6 shows that the upper shell 1 is glued on the middle part 3.
  • the lower shell 2 could, like what has been explained in connection with FIG. 4, be fixed by means of screws screwed on the middle part or on an additional base.
  • a variant of attachment has been shown here which uses a lug 22 which presses the lower shell 2 on the middle by means of a screw 23.
  • the figure shows that the case is devoid of the bottom proper and that the tightness is ensured thanks to a seal 21 interposed between the lower shell 2 and the middle part 3. This way of making the disassembly of the case even simpler, this simplicity having to be paid however by a construction which may be more cumbersome and with fasteners brighter bracelet.
  • FIG. 7 is a section at 6 o'clock in the box of the invention.
  • the strap fixing means consist of a projection 30 emerging under the lower shell 2 and extending outside its periphery. These projections are made in one piece with the middle part but could be attached to it.
  • the projection 30 is provided with a hole 46 intended to receive a bar (not shown) around which a strand of the bracelet can pivot.
  • the shell 2 is provided with cutouts 48 to allow passage to the projection 30.
  • This shell 2 is fixed to the middle by means of lugs 32 tightened by screws 33, like what has been described in FIG. 6.
  • This third embodiment shows a new way of 'secure the upper shell 1 on the middle 3.
  • FIG. 7 shows that this embodiment makes it possible to reduce the height of the watch as much as possible since the strap is attached thereto outside its periphery. This advantage will however come at the price of flashing beads located at 6 o'clock and at 12 o'clock.
  • the shells themselves.
  • the upper and lower shells are spherical caps.
  • the radii of curvature can be equal or unequal depending on the appearance that one wishes to give to the watch.
  • the invention is however not limited to spherical caps, certainly easier to produce than any shells, provided that these caps have contiguous edges at least over part of their periphery.
  • All the shells shown in the figures are preferably made of mineral material, for example sapphire.
  • the crystal is made of sapphire.
  • the bottom or lower shell can also be made of sapphire which increases the interest of the present invention. Therefore, since the crystal and the bottom will preferably be made of a hard material, practically the entire watch case is made of a scratch-resistant material.
  • the glass and the bottom allow better absorption of the shocks they may undergo, by transmission of the shocks to their seat located on the middle part on which they are fixed (implementation of the 'arch effect).
  • the box of the invention offers excellent protection against shocks and pressures to which a wristwatch is exposed. While extra-flat wristwatches were generally relatively fragile luxury watches, the proposed solution combines robustness with great elegance. Thus, such a watch, well resistant to external pressures and aggressions, can be worn without fear of deterioration in all the circumstances of modern life and even under conditions as severe as one can meet in diving under -marine, even if it is not specially designed for this purpose.
  • the lower shell could be made of a material other than sapphire, in steel for example.
  • the advantage of a transparent background however lies in the fact that it allows the mechanism of the watch to be seen and, if the latter is of the automatic winding type, the oscillating weight.
