Definitions

  • the present invention relates to a watch with a metallic rotating bezel in which the rotating bezel is provided with an inner ring of synthetic material sliding on the middle of the watch and comprising at least one second piece of synthetic material, fixed, one two plastic parts, ring or second part, being provided with a toothing and the other part with at least one pawl cooperating with the toothing for positioning the rotating bezel.
  • a watch having such a construction is described in patent CH 662 030.
  • the inner ring of synthetic material and provided with teeth has an L-shaped profile and it is glued in a cylindrical housing of the metal bezel.
  • the pawls are secured to a pawl ring fixed to a cylindrical bearing surface of the middle, around the fixed bezel, by means of a metal tension ring.
  • This ring is also used for the axial retention of the rotating bezel by its synthetic ring.
  • the pawl ring must be assembled with the rotating bezel before mounting this pawl ring on the watch case. Conversely, if one of the elements of the rotating bezel has to be removed, the assembly with the ratchet ring must be removed. If one of the parts of the assembly breaks, the assembly is replaced. In all cases, the replacement of the toothed ring cannot be done without also replacing the metal bezel.
  • the subject of the present invention is a different conception. Its purpose is to allow mounting suc discontinuous and without any special tool, the pawl ring on the middle, then the rotating bezel. In addition, the synthetic part of the rotating bezel must be able to be replaced easily.
  • the watch with rotating bezel according to the invention is characterized in that the inner ring of synthetic material is fixed to the notch to the rotating bezel and that the other piece of synthetic material is held in place on the one hand by at least one foot engaged in a hole provided in the middle and on the other hand by the rotating bezel.
  • the inner ring is therefore fixed without gluing to the rotating bezel, which makes it possible to remove it in the event of a defect and to replace it with a new part.
  • the assembly is very simple: first place the ratchet ring whose feet are introduced into the holes provided for this purpose in the middle part, then the rotating bezel is put in place with its synthetic ring .
  • the rotating bezel can be retained axially, either directly by its synthetic ring having for this purpose an appropriate profile, or by a split assembly ring. In both cases it is the rotating bezel which axially retains the pawl ring.
  • the watch according to the invention also has the advantages of the previous embodiment, namely the possibility of using any material for the rotating bezel and the case by having an easy rotation of this rotating bezel on the box, regularity of the friction, total absence of corrosion at the level of the click-in, precision of the click-up and physical resistance of this one.
  • the rotating bezel watch shown in FIG. 1 comprises a middle part 1 having a bezel 2 in which a crystal 3 is fixed by means of a trim 4.
  • the passage 5 is also shown for the time-setting rod.
  • the middle part 1 Around the fixed bezel 2, the middle part 1 has a flat surface 6 in which three equidistant grooves 7 are formed, in an arc of a circle. Near one end of these grooves 7, the bottom of the groove has a blind hole 8.
  • a pawl 9 in each of the grooves 7 is housed a pawl 9 as shown in Figures 3 and 4.
  • Each of these pawls 9 made of synthetic material has a base 10 of generally rectangular shape and provided with a cylindrical foot 11 which is freely housed in the blind hole 8 of the middle part.
  • the base 10 From the base 10 extends an elastic arm 12 terminated by a ratchet beak 13.
  • the elastic arm 12 is of course thinner than the base 10 so that by bending the arm 12, the ratchet beak 13 can retract completely into the groove 7.
  • the base 10 is provided with vertical beads 14, 15, 16 and 17 at its angles. These beads come to engage in vertical grooves such as 18 provided in the walls of the groove 7.
  • the watch is provided with a metal rotating bezel 19 having a scope 19a covering the fixed bezel 2.
  • the rotating bezel 19 has an annular radial groove 20 and below this groove 20 a flat surface 21 extending as far as a second annular radial groove 22.
  • the grooves 20 and 22 form two notches in which a plastic ring 23 is fixed to the notch having a profile corresponding to the internal profile of the rotating metal bezel 19.
  • the periphery of the synthetic ring 23 has two bevels 23a and 23b allowing the fixing of the ring 23 by simple pressure.
  • the ring 23 is also locked in rotation by at least one boss coming into engagement in a groove 25 of the rotating metal bezel 19.
  • the bosses of the ring 23 can have the shape of the boss appearing in FIG. 6.
  • the ring made of synthetic material 23 has internally an annular projection 26 by which it is retained axially on a notch 27 of the middle part.
  • the ring 23 has a toothed serration 28 cooperating axially with the pawls 9. In this case the rotating bezel 19 can therefore only rotate in one direction. It would however be possible to form a toothing such that the rotating bezel can rotate in both directions.
  • This ring 29 in synthetic material is also provided with a cylindrical foot 30 and a lateral boss 31.
  • the ring 29 is provided with one or more pawls 32 having a pawl beak 33 projecting above the ring.
  • the groove 7 provided in the middle part 1 extends over the entire periphery of this middle part to receive the ring 29.
  • the foot 30 of the ring 29 is housed in a hole identical to the hole 8.
  • the boss 31 it is housed in a groove similar to the groove 25 to fix the ring 29 in rotation.
  • FIG. 7 shows, by way of example, the same bezel 19 fitted with a ring 34 made of synthetic material in which at least one pawl 35 is formed intended to cooperate with a toothed ring housed in place of the pawl ring 29.
  • the ring 34 is identical to the ring 23.
  • FIG. 8 shows an example of execution.
  • the middle part 1 is the same as that of the first embodiment.
  • the metallic rotating bezel 36 is lower than the bezel 19 it is provided internally with a groove 37.
  • the assembly is carried out by means of a split metal ring 38 of rectangular profile provided with two diagonally opposite bevels.
  • the split ring is firstly fixed in a groove 39 of the middle part 1 with a certain radial clearance.
  • the bezel 36 is then engaged with pressure on the assembly ring 38. This first retracts into the groove 39, then relaxes in the groove 37 of the rotating bezel. This method of attachment is well known.
  • the rotating bezel 36 is provided with a toothed ring 40 substantially smaller than in the first embodiment, but also fixed to the notch in a groove 41. This ring 40 is also locked in rotation by at least one boss engaged in a groove 42 of the rotating bezel.
  • the toothed ring 40 works with a pawl ring 29 as shown in FIGS. 5 and 6.
  • the assembly could also be done by means of an unsplit ring.
