Definitions

  • the present invention relates to a timepiece comprising a crystal, a bottom and a middle part having a cylindrical internal wall, the crystal, the bottom and the middle part together defining a box intended to receive a movement provided with display means.
  • the document CH-A-554 560 (GB-A-1.370.528) has already proposed a construction where the glass and the bottom constituting constituent parts of the box are assembled in one and the same middle in which they are driven with interposition, between the edge of each of them and said middle, of a lining ensuring, on the one hand, the sealing and, on the other hand, keeping them in place, the inner surface of the middle part in which the crystal and the bottom are engaged being cylindrical and therefore having no bearing shoulder.
  • the cited construction uses, apart from the mentioned fittings, two additional rings and a spacer forming a casing circle and separating said fittings, therefore to a plurality of parts produced independently of one another, which 'then stack one on top of the other when mounting the box.
  • Document DE-A-34 21 168 describes a tubular lining comprising a projection reducing its internal diameter.
  • the middle part does not have a continuous cylindrical internal wall since a shoulder is provided in the bottom of the middle part, shoulder on which the lining comes to bear. This arrangement complicates the rapid assembly or disassembly of the watch and especially the way of making the middle whose internal wall is not continuous.
  • the timepiece of the present invention is characterized in that a ring is disposed between, on the one hand, the internal wall of the middle part which it completely covers and, on the other hand, the crystal and the movement, said ring comprising an upper zone having a first housing in which at least the glass is engaged, said glass compressing against the middle part the material from which the ring is made to ensure both a tight closure between the glass and said ring and the fixing of said ring on the middle, a central zone having a second housing in which the movement is engaged, said ring serving as a casing circle for said movement, and a lower zone emerging from the middle part, said lower zone comprising means s fixing the bottom to said ring.
  • the timepiece comprises a crystal 1 (FIG. 7), a base 2 (FIG. 3) and a middle part 3 (FIG. 6) , the crystal, the bottom and the middle part together defining a box intended to receive a movement 5 (FIG. 4) provided with display means illustrated by a dial 13 and hands 25.
  • the middle part 3 has a cylindrical internal wall 4, which means that this wall has no recess or support shoulder. This feature is very interesting, because it makes it possible to manufacture the middle part in a single operation and without subsequent recovery.
  • a ring 6 ( Figure 1) is disposed between, on the one hand, the internal wall 4 of the middle part 3 and, on the other hand, the crystal 1 and the movement 5.
  • the wall internal 4 of the middle part is entirely covered by this ring.
  • the ring 6 has an upper area 7 having a first housing 8 in which at least the glass 1 is engaged.
  • the material from which the ring is made is compressed against the middle part 3. Thanks to this, a tight seal is ensured between the glass and the ring as well as the fixing of the ring to the middle.
  • the ring 6 also has a central zone 9 having a second housing 10 in which the movement 5 is engaged, the ring thus serving as a casing circle for the movement.
  • the ring 6 finally comprises a lower zone 11 which emerges from the middle part 9. In this lower zone 11 are made means for fixing the base 2 to the ring 6, as will be explained in more detail below.
  • the ring 6 has a quadruple function: that of first ensuring the tight closure of the top of the case, as well as that of ensuring the fixing of the middle part on the box, that then to serve as a casing circle for the movement and that finally to have means for securing the bottom to the box. It thus combines functions which, in the prior art, were fulfilled by several separate parts from each other, which simplifies considerably assembling the timepiece.
  • This ring, made in one piece, is easy to make even within tight tolerances; it is simple and inexpensive.
  • a plastic material which is sufficiently compressible to ensure a good seal between the crystal and the case will be chosen to make it, this material however remaining hard enough to ensure good hold of the middle as well as good movement guidance.
  • the first housing 8 receives, in addition to the glass 1, a flange 12 (FIG. 5) which provides a well-defined space between the glass and the dial 13 surmounting the movement 5.
  • the outside diameter of the flange is arranged so that said flange can be freely introduced into the housing 8.
  • the flange presses on a shoulder 34 whose thickness corresponds substantially to the thickness of the dial 13.
  • the rotation of the dial is prevented by practicing, in extension of the shoulder 34, two projections 33 ( Figures 1 and 9) which are introduced into two cutouts 32 made in the dial ( Figure 4).
  • the second housing 10 is adapted to the movement 5 which is introduced.
  • the movement 5 is provided with a flange 35 resting on a battue 36 made in the second housing 10.
  • the lower zone 11 of the ring 6 has a third housing 14 in which a lining 15 is housed (FIG. 2).
  • a lining 15 is housed (FIG. 2).
  • FIGS. 9 and 10 show that the ring 6 comprises the combination of a first circle 16 made of plastic material with a second circle 17 made of metal, these two circles being integral with one of the other and forming only a ring 6.
  • the first circle 16 of plastic material is arranged to form the housings 8 and 10 respectively receiving the glass 1 and the movement 5 as described above.
  • the figures thus show that in the first circle is formed the housing 14 receiving the lining 15.
  • the second circle 17, made of metal at least partially occupies the lower zone 11 of the ring 6 emerging from the middle part 3.
  • the means for fixing the bottom 2 to the ring 6 are made in the second circle 17.
  • the means for fixing the bottom comprise a notch 18 formed in the periphery of the second circle, notch in which a flange 19 lifted is raised in the bottom 2.
  • a notch 18 formed in the periphery of the second circle, notch in which a flange 19 lifted is raised in the bottom 2.
  • the underside 20 of the middle rests on the rim 19 of the bottom 2. This arrangement will make it possible to precisely position the middle 3 with respect to the ring 6 and thus avoid the use of a special fitting as was the case in the document cited above.
  • the means for fixing the bottom comprises tappings 21 (generally four) made in the second circle 17, tappings in which screws 22 are screwed through holes 23 made in the bottom 2.
  • tappings 21 generally four
  • the combination of the circles 16 and 17 can be obtained by molding the first plastic circle on the second metal circle to then obtain a ring 6 made in one piece.
  • the metal circle 17 has a shoulder 37 extending towards the movement, shoulder intended to ensure the anchoring of the circles on one another.
  • FIGS. 1 and 8 show that a passage 27 is made in the circle 16 of plastic material, passage having a tube 26 emerging from the ring 6.
  • this passage 27 is introduced a rod 28 time reset once the timepiece is assembled.
  • the middle part at this location (see also FIG. 6) has a housing 31 into which the crown 38 of the rod 28 can penetrate, when the rod is in the normal depressed position.
  • FIG. 1 Figures 1 to 7 have been numbered according to a preferred order of assembly of the parts relative to each other.
  • the ring 6 of FIG. 1 is grasped, a ring produced for example according to the section shown in FIG. 9.
  • the gasket 15 of FIG. 2 is introduced into the housing 14 of the ring 6.
  • On the dial 13 we put the flange 12 of Figure 5 which takes place at the bottom of the housing 8 of the ring 6.
  • the timepiece of the invention is very simple to assemble and does not require any special tools or fitting.
  • This system allows the manufacturer of parts making up the box to deliver to the assembler of the timepiece a pre-assembled assembly uniting the ring 6, the lining 15 and the base 2, which considerably reduces the number of parts present.
  • the assembly order indicated above could however be different, the lining 15 and the bottom 2 being able, for example, to be fitted last. In this case, however, at least one special fitting should be provided to position the middle part relative to the ring when the ice is expelled in said ring.
  • the timepiece produced according to FIG. 10 is assembled in the same way as that exposed above and no special fitting is to be expected whatever the assembly order chosen, since the ring has a projection 24 on which the middle 3 rests.
