Definitions

  • the invention relates to setting mechanisms for which the control rod is a time setting rod and the holding plate is a pull tab.
  • control is by a translational movement and rotation of the rod, by means of a ring which it is provided at its outer end.
  • a ring which it is provided at its outer end.
  • the pull is provided with a stud engaged in the throat of the rod.
  • the zipper is on the dial side of the watch.
  • a screw or a pin is accessible from the bottom side, to allow pushing the zipper so that the stud out of the groove during the operation of setting up and removal of the rod. This operation is delicate because it requires two simultaneous movements, the movement of the zipper and the withdrawal of the rod.
  • a pinion, mounted on the time setting rod, is kinematically connected, by means of a reference, to the time setting train or to the date correction wheel, according to the position of the rod.
  • the movement of the pinion against the first return is provided by a mechanism consisting of the zipper and a rocker.
  • the puller cooperates with the rocker by its end opposite to that bearing the stud.
  • the rocker then moves the pinion, pressing on one or the other side of a groove in the thickness of the pinion.
  • This mechanism is well known to those skilled in the art and is, for example, described in the book of watchmaking theory of Chs-A Reymondin et al, page 40 (Federation of Technical Schools of Switzerland, 1998, ISBN 2-940025 ).
  • the present invention proposes a solution facilitating the removal and setting up of the time setting rod without having to simultaneously push the zipper free of the aforementioned drawbacks.
  • the invention relates to a control mechanism as mentioned above, wherein the locking piece comprises two wings intended to cooperate with the rod by engagement in the groove, to limit the displacement in translation.
  • the locking piece is arranged so that it is capable of occupying a first, so-called locking position, in which the translational movement of the rod is limited by the engagement of the wings in the groove and a second position. , said unlocking, wherein the locking piece is no longer engaged in the groove, allowing the establishment of the rod on the frame or withdrawal.
  • control mechanism consisting of a time-setting rod which can end with a pinion which is integral with it in rotation and in translation and a holding plate consisting of a pull rod which can to be mobile in translation.
  • the locking piece has positioning means ensuring its retention in the locked and unlocked positions. They are formed by a frictional engagement of a portion of the locking piece on the holding plate and, in a particularly advantageous embodiment, by the wings, which extend on the sides of the groove beyond its bottom. , and whose free end wife, in the locked position, the contour of the inner diameter d , so as to define a notch engagement.
  • a movement part of a watch is shown, and more particularly a frame, for example a plate, provided with two parallel faces defining a reference plane, one of which is intended to carry a dial and the other is found next to the bottom.
  • a setting rod 12 provided with an annular groove 14 having a width I , an outside diameter D and an inside diameter d , is mounted to move in translation and in rotation in the frame 10, along a first axis ( AA ') included in the reference plan.
  • the end of the rod 12 inserted in the mechanism of the watch consists of a set of teeth 16, cooperating with a time-setting deflection, which is not shown in the drawing, and which pivots on a stud 18.
  • a pull tab 20 is movably mounted in translation in the reference plane. It carries the stud 18 and has a locking piece 22 cooperating with the rod 12 by engagement in its groove 14, thus making the rod 12 and the pull tab 20 integral in translation.
  • the pull tab 20 also positions the rod 12 in the thickness of the movement.
  • the pull tab 20 is provided with holes 24 in which plots attached to the frame engage, not shown in the drawing, in order to ensure its guidance during its movements in translation.
  • the locking piece 22 is arranged in such a way as to occupy two positions, ie one of said locking positions, in which the rod 12 and the pull tab 20 are integral in translation and the other, so-called unlocking, in which it is possible to remove the rod or put it in place.
  • the piece 22 comprises a first central portion 26, of generally cylindrical shape, a first portion 28 is frictionally engaged in the pull tab 20 to allow its rotation along a second axis BB ', which fictitiously passes vertically through the center of the throat 14 when the rod is in place and a second portion 30, of greater diameter, is engaged in a hole 32 formed in the thickness of the pull tab 20 and bears against its bottom, so as to axially position the piece 22.
  • a second portion 34 of the locking piece 22, upper, is provided with a slot 36 passing therethrough radially, so as to allow the engagement of a flat screwdriver to rotate the piece 22.
  • the piece 22 ends, on the side of the time setting rod 10, by a third portion 38 which comprises two wings 40, separated by an opening 42 passing therethrough horizontally, and arranged symmetrically with respect to a vertical plane which, in the unlocked position, includes the axis AA '.
  • the wings 40 are intended to cooperate with the groove 14 when the piece 22 is in the locked position.
  • they are dimensioned so that they are inscribed in a fictitious cylinder of axis coinciding with the second axis BB 'and of diameter slightly smaller than the width of the groove 14.
  • the locking piece 22 is rotatable along the axis BB '.
  • the wings 40 of the portion 38 of the piece 22 are arranged such that in the locked position, visible on the figure 1c they are inscribed in the outer diameter D of the groove 14 and follow the contour of the internal diameter d .
  • the wings 40 of the portion 38 thus occupy substantially all the space between the walls of the groove 14, so that the rod 12 and the pull tab 20 are integral in the movements in translation.
  • a rotation of a quarter turn of the locking piece 22 makes it possible to move to the second unlocked position, visible on the Figure 2c , in which the flanges 40 follow the contour of the outside diameter D of the groove 14.
  • the axis AA ' is then included in the plane of symmetry of the flanges 40. In this position, the groove 14 is released and the rod 10 can be moved in translation independently of the pull tab 20, to allow its introduction or removal.
  • the wings 40 in the locked position, extend on the sides of the groove 14, beyond its bottom, their free end conforming to the contour of the inner diameter d to maintain the locking by a notch.
  • the applied rotational force must overcome the elastic resistance forces exerted by the rod 12 and the pull tab 20.
  • the wings 40 press on the bottom of the groove 14 and slightly move the rod 12 and the pull tab 20, to allow their passage and the transition to the unlocked position.
  • the middle part 26 can be mounted free on the pull tab 20, the position of the locking piece 22 being provided by the notch.
  • the holding plate of the locking piece can be fixed. It may also be a rocker controlled by the pusher and part of, for example, a chronograph mechanism.
