Definitions

  • the present invention relates to the field of watchmaking. It relates more specifically to a function control device or correction for a timepiece.
  • control devices are generally constituted by pushbuttons arranged on either side of the crown, on the sides of the box.
  • the control devices are generally constituted by pushbuttons arranged on either side of the crown, on the sides of the box.
  • pushbuttons For aesthetic reasons, or to create a surprising effect, it may be interesting to replace these push buttons by more discreet control devices, integrating, for example, to the upper face of the box.
  • Requirement EP 1,580,626 describes such a device equipping a watch comprising a box in which is housed a movement provided with an indicator mechanism.
  • This device comprises a control lever located outside the box and operable by the user, an operating lever located inside the box and cooperating with the indicator mechanism, and a rod interconnecting between them rigidly.
  • the pivoting of the outer lever under the action of the user rotates, via the rod, the actuating lever which cooperates with the indicator mechanism to perform a correction.
  • the control lever is advantageously located in a recess in a horn, to be easily accessible, while remaining inconspicuous.
  • the device thus described is an alternative to a traditional push button, or comes in addition, in case the pushbuttons are not enough.
  • the device according to the invention performs the same function, while integrating even better with the watch, since the control lever becomes invisible.
  • the timepiece further comprises a bezel mounted rotatably on the middle part, the bezel having a contact surface arranged to cooperate with the bearing surface when it rotates, so as to cause the transmission member in rotation.
  • control device makes it possible to control or correct a function from the telescope, without the intervention of pushbuttons.
  • the aesthetic appearance of the watch is significantly improved, without the functionality is changed.
  • the watch partially shown in FIGS. 1 and 2 conventionally comprises a box 10 formed of a middle part 12 and a bottom 14 defining together an interior volume 16 in which is mounted a movement 18 via a circle of The movement 18 extends in a plane P substantially parallel to the plane defined by the bottom 14.
  • This movement may be purely mechanical or electromechanical type powered by a source of electrical energy not shown.
  • a control lever, not shown, of a start / stop function of a stopwatch is mounted on the movement 18. This lever cooperates with an intermediate piece 24 slidably mounted in an opening 26 passing through the casing ring 20 and intended to allow access to the control lever, from the middle 12, through the casing ring 20.
  • the opening 26 will be better described later, with reference to Figure 3.
  • a mirror 27 is mounted in a sealed manner on the middle part 12.
  • the watch shown in FIGS. 1 and 2 further comprises a control device 28 intended to cooperate with the control lever and formed by a telescope 30 and a transmission member 31.
  • the middle part 12 comprises, in its upper portion, a substantially circular clearance 32 forming a bearing surface 34, parallel to the plane P, and a guide surface 35 perpendicular to the plane P, on which the bezel 30 is rotatably mounted according to a technique well known to those skilled in the art.
  • a return spring not visible in Figures 1 and 2, returns the bezel 30 to its initial position after rotation.
  • the bezel 30 is formed of two parts 30a and 30b, integral with each other, the first assuring the mounting on the middle part 12, and the second extending substantially radially around the ice 27.
  • the telescope 30 could be monobloc.
  • the transmission member 31 comprises a cylindrical rod 36, rotatably mounted inside a hole 38 of axis XX substantially perpendicular to the plane P, passing through the middle part 12, from the bearing surface 34 to a cavity 40, formed inside the middle part 12.
  • the cavity 40 opens itself on the internal volume 16, facing the opening 26.
  • the hole 38 extends beyond the cavity 40, in the 12, by a blind hole 42 which is coaxial with it.
  • the cylindrical rod 36 has a groove 44 in which is mounted a seal 46. It has a first end circular section engaged in the hole 42 so as to optimize its rotational guidance along the axis XX. Its portion located inside the cavity 40 further comprises a section with a square section on which is mounted a first cam 48, pierced with a square section hole 50. In a variant, said section and the cam 48 are triangular or hexagonal section, or any form adapted to the transmission of a couple.
  • the height of the cavity 40 is substantially equal to the height of the cam 48 so that the latter can be housed there, while being locked axially on the rod 36.
  • the cam 48 is locked axially in the direction the hole 42 by an elastic ring, and, in the direction of the hole 38, by the bearing between the section of the rod 36 of square section and the portion with cylindrical section.
  • the height of the cavity 40 is arbitrary.
  • the cam 48 is shown in section along a plane substantially parallel to the plane P in FIG. 3. With a substantially elongated shape, the cam 48 is mounted off center on the rod 36. It comprises a first end forming a flat portion 52, and a second forming a stop 54 intended to limit the rotational travel of the cam 48 inside the cavity 40.
  • the abutment 54 bears against the side wall of the cavity 40, the flat 52 comes into contact with the intermediate piece 24 housed in the opening 26.
  • the opening 26 forms a portion of a circle in which the cam 48 is free to move, over a certain angular sector, when it rotates about the axis XX.
  • the second end of the rod 36 is formed of a second cam 56 located outside the middle part 12 and extending partially on the bearing surface 34.
  • the cam 56 and the rod 36 form a single piece produced by cutting or machining.
  • the cam 56 could be glued or welded to the rod 36.
  • the cam 56 and the clearance 58 are shown in section along a plane substantially parallel to the plane P in FIG. 4.
  • the cam 56 forms substantially an eight of which one of the lobes is centered on the axis XX, and the other lobe forms a bearing surface 59 extending substantially radially.
  • the clearance 58 comprises a recess 61 forming a contact surface 62, extending perpendicular to the plane P, and intended to cooperate with the bearing surface 59 so as to drive the cam 56 in rotation when the telescope 30 rotates.
  • the mounting of the control device 28 operates as follows.
  • the cam 48 is positioned in the cavity 40, its square section hole 50 being disposed opposite the holes 38 and 42.
  • the rod 36, integral with the cam 56 is inserted into the through hole 38 to the blind hole 42 through the hole with square section 50.
  • the telescope 30 is mounted so that the cam 56 takes place inside the housing 60.
  • the relative orientation of the cams 48 and 56 is such that, when the stop 54 is supported on the wall of the cavity 40, the longitudinal axis of the cam 56 is substantially perpendicular to the displacement of the telescope 30.
  • the rod 36 is locked axially, in one direction by the cam 56, and in the other meaning by the telescope 30.
  • the control device is used to control the start and stop of a stopwatch. Alternatively, it could be used to correct an indication, such as a day of the week, or moon phases, or to control any other function, such as winding a countdown spring. Its operation is as follows. When the telescope 30 is in its initial position, the contact surface 62 is located in the vicinity of the cam 56 and the flat 52 comes into contact with the intermediate part 24. When the user actuates the telescope 30 in rotation, the surface of contact 62 comes to exert a thrust on the bearing surface 59, thereby rotating the cam 56 about the axis XX. This pivoting movement is transmitted to the cam 48 via the rod 36.
  • the cam 48 then presses on the intermediate piece 24, which actuates the function control lever, thus starting the stopwatch.
  • the shape and size of the opening 26 are such that the flat 52 abuts the wall of the opening 26 after having actuated the intermediate piece 24.
  • the telescope 30 returns to its position initial action by the action of the return spring.
  • the transmission member 31 returns to its initial position under the action of the control lever, provided with a return spring.
  • a second control device can be mounted symmetrically to the first.
  • the bezel 30 has a circular recess 58 forming a housing 60 in which are housed a first cam 56 and a second cam 64 respectively belonging to a first transmission member 31 and a second transmission member 66.
  • the housing comprises a first recess 61 and a second recess 68 forming a first contact surface 62 and a second contact surface 70 disposed opposite one another so as to actuate the transmission members 31 and 66 respectively in one direction of rotation and in the other.
  • the second transmission member 66 actuates, for example, resetting the stopwatch.
  • the cam 56 integral with the end of the rod 36 located outside the middle part 12 can be replaced by a toothed wheel.
  • the rotating bezel 30 is then provided with a toothed sector which is substituted for the contact surface 62, and intended to cooperate with the toothed wheel so as to drive the transmission member 31 in rotation.
  • any part comprising at least one bearing surface extending substantially radially so as to cooperate with at least one contact surface belonging to the telescope, may be mounted at the outer end of the rod 36 so as to rotate it.
  • control device comprises a rod 36 passing through the middle part 12 along an axis XX substantially perpendicular to the plane P defined by the bottom.
  • the rod 36 could extend parallel to the plane P while being engaged radially in the middle part 12.
  • the movement 18 is mounted in the box 10 by means of a casing ring 20. It goes without saying that all the possibilities for mounting the movement in the box is compatible with the control device according to the invention.
  • the cam 48 acts directly on the function control lever without an intermediate part 24.
