Definitions

  • the invention relates to a timepiece, such as a wristwatch, the movement of which is held inside the case by a damping device serving to protect the movement in the event of impact.
  • the object of the present invention is to overcome all or part of the aforementioned drawbacks by proposing a timepiece comprising a shock-absorbing device for the movement and allowing simplified assembly of the timepiece.
  • the invention relates to a timepiece comprising a case comprising a middle part closed, in its upper part, by a bezel and, in its lower part, by a back, a watch movement mounted against the middle part at using a casing circle characterized in that that it further comprises a blocking device enabling the watch movement/casing ring assembly to be pressed against the middle part when the case of the timepiece is closed.
  • the assembly of the timepiece comprises a minimum number of parts and thus adapts more easily to the manufacturing dispersions of the various components while maintaining advanced technicality with, in particular, a chronograph, a date, a mechanical movement, a transparent back and a plastic caseband.
  • a timepiece according to the invention comprises a middle part 2 closed, in its upper part, by a bezel 3 and, in its lower part, by a back 4, a watch movement 5 and a dial 6 mounted against the middle part 2 using a casing ring 7.
  • middle part 2 defines a housing 6 in which is housed a shock-absorbing device for the watch movement, the damping device comprising an upper annular part 11 and a lower annular part 12 arranged to be assembled on the assembly formed by the movement, the dial and the casing circle.
  • the caseband 22 is made of metal or metal alloy, however, any other type of material is possible such as, for example, plastic or ceramic.
  • the bezel 3 and the back 4 are also made of metal or metal alloy, and at least the bezel includes a crystal 30.
  • the movement 25 is preferably of the mechanical type, but a quartz movement could also be envisaged.
  • the middle part 2 is intended to receive the watch movement 5 by means of at least one shoulder 10 made in its internal wall, the movement 5 being mounted on the shoulder 10 of the middle part 2 by means of the shock absorber device, the shock-absorbing device enveloping the movement, the dial and the casing ring 7.
  • the shock-absorbing device is intended to adapt the movement 5 against the internal wall of the middle part 2.
  • the casing ring 7 comprises a globally annular body formed by an upper part 70 and a lower part 71, the upper part being arranged to receive the dial and the lower part being arranged to receive the movement 5.
  • the upper part 70 has a larger diameter than that of the lower part 71 and thus forms a shoulder.
  • the upper part 70 has at least one notch 18 as well as a discontinuous peripheral rim 19' to orient and hold the dial 6 in place on the casing ring 7, the dial 6 also having lugs 60 resting against the edges of the notch 18.
  • the lower part has a groove 19 arranged to cooperate with a plate 50 of the movement 5 to orient and hold the latter in place.
  • the shock absorber device comprises an upper annular part 11 and a lower annular part 12 which each have a conical surface 15, 20 arranged to cooperate with a shoulder of the middle part 10 or a shoulder of the back 4.
  • the parts upper 11 and lower 12 rings are advantageously made of an elastomeric material such as natural or synthetic rubber in order to be able to absorb/dampen shocks.
  • the upper annular part 11 comprises on its outer side face orientation means with respect to the middle part 2.
  • the orientation means are in the form of tabs 13 forming a curved relief on the surface of the circumference of the annular part upper part 11, the tabs 13 being arranged to cooperate with recesses 13' of complementary shape formed on the inner wall of the middle part 2. It is therefore understood that the upper annular part 11 is mounted against the middle part 2 and the conical surface 15 is presses on the shoulder 10 of the caseband 2.
  • the upper annular part 11 also comprises orientation means with respect to the casing ring 7, and implicitly with respect to the movement 5, the orientation means being in the form of at least one projecting element 14, formed on the inner side face of the annular part 11, and arranged to cooperate with a cutout 17 of complementary shape at the level of the upper part of the casing circle 7.
  • the lower annular part 12 comprises at least one machining 22 on its outer side face which is arranged to cooperate by interlocking with the at least one projecting element 14 of the upper annular part 11.
  • the lower annular part 12 also comprises an upper edge 21 arranged to rest against the upper part of the casing ring 7. It is therefore understood that the fitting circle 7 and the dial 5 are clamped between the upper annular part 11 and the lower annular part 12 when the whole is assembled as in figures 4a and 4b .
  • the upper annular part 11 and the lower annular part 12 each comprise a passage for a winding stem 51 so as to be able to insert the latter during assembly.
  • other passages can be provided for the push rod passage for example.
  • the timepiece comprises a ring 8 arranged to be placed between the back 4 and the lower annular part 12 to hold the shock-absorbing device once the back of the watch is assembled on the middle part.
  • case 23 it is also possible for the case 23 to be partially closed, that is to say that it comprises a back or a bezel in one piece with the middle part.
  • the middle part could be replaced by a case kept closed by the bezel only.
  • the middle part could be replaced by a box kept closed by the back only.
