Definitions

  • the invention relates to a device for blocking a movement of a timepiece and, more particularly, such a device for immobilizing an automatic or quartz mechanical movement.
  • the object of the present invention is to overcome all or part of the aforementioned drawbacks by proposing a timepiece comprising a locking device without screws and/or fixing flange 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 ring characterized in that the casing ring comprises at least two clippable parts which hold the watch movement, the two parts being inseparable once mounted against the middle part when the case is closed the timepiece.
  • 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 100 mainly comprises a case 10, a watch movement 4 and a casing ring 5.
  • the case 10 comprises a middle part 1 closed, in its upper part, by a bezel 2 and, in its lower part, by a back 3, the middle part 1 being intended to receive the watch movement 4 fitted with the casing ring 5.
  • the caseband 22, the bezel and the back are made of metal or metal alloy, however, any other type of material is possible, such as, for example, a plastic material, a ceramic or even a composite material.
  • the watch movement 25 is preferably of the mechanical type, but a quartz movement can also be used without any problem.
  • the movement 4 is mounted on the shoulder 28 of the middle part 22 by means of a casing circle 45.
  • the casing circle 5 is intended to adapt and maintain the movement 4 against the internal wall of the caseband 22.
  • the casing ring 5 is in the form of a generally annular body, the outer wall of which comprises at least one shoulder 44.
  • the casing ring 5 comprises at least two parts 50, 51 which can be clipped together and which hold the watch movement 4.
  • the two parts 50, 51 are inseparable once they are assembled and mounted against the caseband 1 during the closing the box 10.
  • the two clippable parts 50, 51 are in the form of two semi-annular parts whose face facing the movement 4, or even the internal face, comprises a groove 56 cooperating with a plate 40 of the watch movement 4 in order to guarantee the positioning and maintenance of the latter when the two parts are clipped.
  • each part 50, 51 is placed on either side of the watch movement 4 so that the plate rests in the grooves 56.
  • the two parts 50, 51 each comprise at least one male element 54 and one female element arranged to be clipped one inside the other, the male part comprising a body and a head arranged to cooperate by interlocking with a recess in the part female.
  • one of the parts 50 comprises at each of its ends a male element and the other part 51 comprises at each of its ends a female element. It is also possible to have each part 50, 51 with a male element and a female element, the position of the male and female elements being opposite.
  • the male element 54 has a body 540 of rectangular section and a head 541 of trapezoidal shape, the head being in the extension of the body.
  • the female element comprises an orifice 53 arranged on the edge of the part 51, the orifice being of complementary shape to the head 541 of the male element so that the latter can be inserted into the orifice.
  • the female element also comprises an opening 55 arranged on the top of the part 51 and opening into the orifice 53, the opening 55 being arranged to cooperate with the head 541 of the male element 54 and thus allow assembly by clipping.
  • the present invention describes a casing circle 5 comprising two parts 50, 51 clippable together, but a person skilled in the art would have no difficulty in making a casing circle in three or four parts, for example.
  • a minimum number of parts is desirable, two parts in the present case of the invention, so as to ensure good rigidity of the assembly and better support.
  • the circle in two parts makes it possible to limit assembly clearances as well as the number of parts likely to break.
  • each shoulder 44 is intended to come into contact with the shoulder 28 of the middle part 22.
  • casing 45 is preferably indented in order to free up the space respectively around the mechanical controls 53, 55 of the chronograph and the control hole 54 of the time-setting device and, possibly, of the date device.
  • one of the parts 50 comprises a positioning lug 6 arranged to cooperate with a notch 7 of corresponding shape made in the watch movement 4 to ensure the orientation of the movement with respect to the casing circle, and implicitly with respect to the middle of the watch case.
  • the clippable parts 50, 51 comprise an upper portion 57, a middle portion 58 and a lower portion 59.
  • the upper portion 58 receives the groove 56 on the internal face and has an outer diameter greater than the diameter of the middle and lower portions so as to form a shoulder intended to be in contact with the middle part. This contact makes it possible to adjust the height of the casing ring 5, and therefore of the movement 4, with respect to the caseband.
  • one of the clippable parts 50, 51 has, at the middle portion 58, a through hole 9 for the passage of a winding stem 8.
  • the lower portion 59 of the casing ring 5 has an internal diameter slightly smaller than the internal diameter of the upper and middle portions so as to envelop the watch movement 5 and limit the movements of the latter in the event of shocks for example.
  • the movement 25 is prepared and the two parts 51, 51 are arranged on either side of the latter so as to match the plate 40 with the groove 56, and to match the positioning lug 6 with notch 7 of the movement.
  • the guiding of the parts 50, 51 is improved by the interaction of the positioning lug present on the casing ring 5.
  • a second step 7 parts 50 and 51 are pressed against watch movement 5 so that plate 40 rests in groove 56 and the male elements clip into the female elements. The operator knows that the assembly is complete when he hears the characteristic noise of clipping assemblies, which is here reproduced by the passage of the head 540 in the opening 55.
