Definitions
- the present invention relates to control mechanisms of a timepiece of the type comprising: - a frame, provided with two parallel faces, one of which is intended to carry a dial and the other is located opposite the bottom ,
- control rod mounted movable in translation on the frame and comprising an annular groove
- the invention relates to time-setting mechanisms for which the control rod is a time-setting rod and the holding plate is a pull tab.
- control is effected by a translational and rotational movement of the rod, by means of a crown with which it is provided at its outer end.
- a translational and rotational movement of the rod by means of a crown with which it is provided at its outer end.
- the pull tab is provided with a stud engaged in the groove of the rod.
- the pull tab is on the dial side of the watch.
- a screw or a pin is accessible from the bottom side, to allow the pull tab to be pushed back so that the stud comes out of the groove during the operation of placing and removing the rod.
- This operation is delicate, because it requires two simultaneous movements, namely the displacement of the pull tab 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 the date correction train, depending on the position of the stem. The movement of the pinion against the first return is ensured by a mechanism composed of the pull tab and a rocker.
- the zipper cooperates with the lever by its end opposite to that carrying the stud.
- the rocker then moves the pinion, pressing on one or the other of the sides of a groove formed in the thickness of the pinion.
- This mechanism is well known to those skilled in the art and is, for example, described in the clock theory book of Chs-A Reymondin et al, page 40 (Federation of Swiss Technical Schools, 1998, ISBN 2- 940 025).
- Patent CH 8 819 describes a time-setting mechanism in which the zipper is on the bottom side and whose zipper stud is replaced by a pivot screw, which thus prevents any translational movement of the rod. It is therefore necessary to loosen the screw to release the rod.
- This device has at least two major drawbacks. First of all, the lever through which the screw passes must be thick enough to make a thread capable of holding the screw securely. This increases the thickness of the movement accordingly. Furthermore, it is never guaranteed that a tight screw will not loosen under the effect of vibrations.
- the present invention provides a solution that facilitates the removal and installation of the time-setting rod without having to simultaneously push the pull tab and avoiding the drawbacks of the solution proposed in the aforementioned patent.
- the invention relates to a control mechanism for a timepiece of the type comprising a frame provided with two parallel faces defining a reference plane, one of which is intended to carry a dial and the other is next to the bottom.
- the mechanism also includes, integral with this frame: - a control rod provided with an annular groove having a width I, an external diameter D and an internal diameter d, mounted movable in translation in the frame along a first axis AA 'included in said plane, and - a retaining plate mounted on the frame parallel to the plane and comprising a locking part cooperating with the rod by engagement in the groove, to limit its displacement in translation.
- the retaining plate is mounted on the bottom side and carries the locking piece, mounted movable in rotation about a second axis BB 'perpendicular to the reference plane. It is arranged so that it is capable of occupying a first position, called the locking position, in which the displacement in translation of the rod is limited by the engagement of the locking piece in the groove and a second position. , called unlocking, in which said part is no longer engaged in the groove, thus allowing the establishment of the rod on the frame or its removal.
- the locking piece comprises:
- a third part arranged on the side of the rod, intended to cooperate with it and comprising, for this purpose, two wings inscribed in a fictitious cylinder of axis coincident with the second axis BB 'and of diameter slightly less than the width I of the groove, said wings being arranged so that, in the locked position, they are inscribed in the outside diameter D of the groove and conform to the contour of the inside diameter d and, in the unlocked position, they follow the contour of the outside diameter D.
- 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 with a holding plate consisting of a pull tab which can be mobile in translation.
- the locking piece prefferably includes positioning means ensuring its maintenance in the locked and unlocked positions. They are formed by a friction engagement of part of the locking piece on the retaining 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 follows, in the locked position, the contour of the internal diameter d, so as to define a notched engagement.
- FIG. 1a, b, c and 2 a, b, c are representations of a mechanism according to the invention, in the locked and unlocked position, respectively in perspective turned over at b, in longitudinal section at a and transverse at ç along the axis of the rod.
- a part of the watch movement is shown, and more particularly at 10 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 next to the bottom.
- a time-setting rod 12 provided with an annular groove 14 having a width I, an outside diameter D and an inside diameter d, is mounted movable in translation and in rotation in the frame 10, along a first axis ( AA ') included in the reference plane.
- the end of the rod 12 inserted into the mechanism of the watch consists of a toothing 16, cooperating with a time setting reference, which is not shown in the drawing, and which pivots on a stud 18.
- a pull tab 20 is mounted movable in translation in the reference plane. It carries the stud 18 and has a part. locking 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 makes it possible to position the rod 12 in the thickness of the movement.
- the pull tab 20 is provided with holes 24 in which engage studs fixed on the frame, not shown in the drawing, in order to ensure its guidance during its translational movements.
- the locking piece 22 is arranged so as to be able to occupy two positions, one called locking, in which the rod 12 and the pull tab 20 are secured in translation and the other, called unlocking in which it is possible to remove the rod or put it in place.
- the part 22 comprises a first central part 26, of generally cylindrical shape, a first portion 28 of which is engaged in friction in the pull tab 20 to allow its rotation along a second axis BB ', which, fictitiously, passes vertically through the center of the groove 14 when the rod is in place and a second portion 30, of greater diameter, is engaged in a recess 32 formed in the thickness of the pull tab 20 and resting against its bottom, so as to axially position the part 22.
- a second part 34 of the upper locking piece 22 is provided with a slot 36 passing through it radially, so as to allow the engagement of a flat screwdriver to rotate the piece 22.
- the piece 22 is ends, on the side of the time-setting rod 10, with a third part 38 which has two wings 40, separated by an opening 42 passing through it horizontally, and arranged symmetrically with respect to a plane vertical which, in the unlocked position, includes the axis AA '.
- the wings 40 are intended to cooperate with the groove 14 when the part 22 is in the locked position. To this end, they are dimensioned so that they are inscribed in a fictitious cylinder with an axis coincident with the second axis BB ′ and with a diameter slightly less than the width I of the groove 14.
- the locking piece 22 is therefore movable in rotation along the axis BB '.
- the wings 40 of the part 38 of the part 22 are arranged so that in the locked position, visible in FIG. 1c, they are inscribed in the outside diameter D of the groove 14 and follow the outline of the inside diameter d.
- the wings 40 of the part 38 thus occupy practically the entire space between the walls of the groove 14, so that the rod 12 and the pull tab 20 are integral in the translational movements.
- a quarter-turn rotation of the locking piece 22 makes it possible to pass to the second unlocked position, visible in FIG. 2c, in which the wings 40 follow the outline of the outside diameter D of the groove 14.
- the axis AA ' is then included in the plane of symmetry of the wings 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 it to be put in place or removed.
- a locking piece has been produced which makes it possible to pass, without dismantling parts, from a locked position to an unlocked position, these two positions being stable.
- the time-setting rod and the zipper are perfectly secured in translation, while in the unlocked position, the rod can easily be removed or put in place.
- the wings 40 in the locked position, extend over the sides of the groove 14, beyond its bottom, their free end conforming to the contour of the internal diameter d to ensure that the locking is maintained by a notch.
- the applied rotational force must overcome the elastic resistance forces exerted by the rod 12 and by 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 freely mounted on the pull tab 20, the position of the locking piece 22 being ensured by the notch.
- the locking plate for the locking piece can be fixed. It can also be a rocker controlled by the pusher and forming part, for example, of a chronograph mechanism.
