Definitions

  • the present invention relates to a part timepiece including a time-setting mechanism direct action of the pull tab on a timer return, said mechanism making it possible to save a rocking thanks to the particular conformation of said zipper.
  • the invention relates more particularly to a watch with analog display equipped with such a setting device on time.
  • Swiss Patent No. 583,933 describes a mechanism in which the decoupling of a reference intermediate, held in gear position by a elastic tongue, is obtained by the action of a staff tapered from the end of the winding stem on the end of the return shaft.
  • the movement printed on the winding stem activates a puller which acts on an intermediate movable member, generally constituted by a rocker including an arm causes decoupling or meshing of a reference intermediate with the timer wheel.
  • an intermediate movable member generally constituted by a rocker including an arm causes decoupling or meshing of a reference intermediate with the timer wheel.
  • This principle has resulted in many variations.
  • Swiss Patent No 613 588 in which the decoupled position, also called neutral position, or geared for setting the time, is obtained by the vertical displacement, i.e. perpendicular to the plane general of the watch, of a sliding pinion by means of a angled blade acting like a rocker in a plane perpendicular to the general plane of the watch, said blade being itself solicited by an arm of the pull which is controlled by the time-setting rod.
  • the mechanism according to the present invention belongs to the previous category, but differs in that the kinematic chain is shorter thanks to a simplified construction in which the movable member intermediate, interposed between the pull tab and a pinion player to allow engagement or decoupling of the timer wheel is deleted.
  • the invention relates to a part timepieces having at least one analog display including a time-setting mechanism by means of a intermediate return delimited by a head and a base movable along an axis perpendicular to the general plane of the platinum of said timepiece enters at least one neutral position in which said reference 10 is decoupled a timer wheel and a time setting position in which it meshes with said timer wheel, said intermediate reference being moved from one to the other position by translation of a setting rod the hour provided with a circular groove cooperating with a pull tab, characterized in that the intermediate return is biased at its base by elastic means towards the time setting position and that the zipper has an arm that can act directly on the head of the intermediate return to oppose by elastic means and bring said intermediate return to neutral position.
  • the elastic means is for example formed by a clutch spring.
  • the time setting mechanism includes a leaf spring, one end of which is fixed to the platinum.
  • the arm attack of the pull tab on the head of the intermediate return is facilitated by giving the end of the arm a shape tilted outward from the general plane of the room and making a chamfer on the said end of the intermediate return.
  • the zipper arm can have a simple chamfer and the end of the intermediate return have a shape conical or frustoconical.
  • the mechanism basically comprises, on a P stage defining the general plan of the timepiece, a rod 1 for actuating a pull tab 4 which acts directly on an intermediate reference 10, mobile on a shaft 13 - visible in the sectional figures - perpendicular to the general plane of the timepiece, by applying pressure in the direction of the shaft 13 against the elastic force of a clutch spring 15, now thus the intermediate reference 10 disengaged from the timer wheel 20.
  • the timer that causes the display by hands is therefore completely disconnected from the kinematic chain of setting the time.
  • the pull tab 4 consists of a body 5 of generally elongated shape with one end pivoted on the plate on a pad 3 and includes a control arm 6 oriented substantially perpendicular to the body 5 and cooperating with a circular groove 2 of the rod 1, and the other end of which has a second arm 7, having an end 8 inclined towards the outside of the platinum P.
  • the arm 7 presses on the head 11 of the reference intermediate 10 by opposing the opposite force exerted by the leaf spring 15 whose free end 16 requests the base 12 of the return and the other end of which 17 is integral with the plate, so that the wheel timer 20 is decoupled from the intermediate return.
  • Figures 3 and 5 are top views corresponding to the positions shown in Figures 1 and 2 and allowing a better understanding of the functioning of the mechanism according to the invention.
  • the section along the broken line IV-IV of Figure 3 shows successively, from left to right, the plate, then the middle part of the control arm 6 to the stud 3, the body 5 of the pull tab 4 to the arm 7 and finally the intermediate return 10 whose base 12 is requested by the clutch spring 15 secured to the plate P by its end 17.
  • this leaf spring can be an elastic piece ensuring only the function clutch, or on the contrary an element of a part performing other functions, such as a branch of a long necklace.
  • the pull tab 4 may include elements for other functions as shown schematically by the pin 9, visible on the views in perspective and on top views.
  • Figures 3 and 4 also show a first reference 21 engaged with a second reference 22, itself engaged permanent with intermediate reference 10, whatever its positioning along its axis 13.
  • Figures 6 and 7 which are the views respectively according to section VI-VI of Figure 5 and according to section VII-VII of figure 3 show even more clearly the position of the different mobiles, respectively in time setting position and neutral position.
  • the arrows shown in these figures show respectively the direction in which the force of the spring 15 in the time setting position and the direction in which exerts the pressure of the arm 7 of the pull tab 4 in neutral position.
  • the first reference 21 includes a crown teeth which mesh with a pinion (not shown) mounted on a square 24 of the control rod 1, said pinion generally being a sliding pinion.
  • the time-setting mechanism according to the invention therefore offers an economic advantage by eliminating a flip-flop, a construction advantage by providing a gain of space related to said deletion and an advantage in terms of the longevity of the timepiece, given that the kinematic chain is at rest in neutral position. This last point also helps reduce torque driving the hands by the timer wheel, and thereby the energy consumption, which contributes a definite advantage, especially in the case of a room electronic clock powered by a battery.
