Definitions

  • the present invention relates to timepieces having a control mechanism comprising elements pivotally mounted on a frame.
  • the invention relates, more particularly, to a timepiece of this type equipped with a mechanism bridge which is fixed on the plate and which serves as a pivot bearing for at least one of these pivoting elements.
  • This control mechanism usually comprises a rod mounted to rotate and axially sliding on a frame, a sliding pinion mounted on the rod and pivoting elements forming a connecting mechanism used to kinematically connect, in axial translation, the rod and the sliding pinion, as well than to determine several stable axial positions of the rod and the sliding pinion.
  • These pivoting elements usually include a puller cooperating with a jumper spring, and a rocker acting on the sliding pinion.
  • An object of the present invention is to produce a timepiece having a plate made up, at least in part, of plastic material, and in which the relative positions of the pivot axes of the various pivoting elements are ensured with precision, this piece d watchmaking should also be simple in design and easy to assemble.
  • each pivot element both pivots in the mechanism bridge and includes a member coaxial with its pivot axis, this member taking place in a respective recess in the plate and serving for the pre-positioning of said pivoting member.
  • each of the pivoting elements is first put in place on the plate where it is pre-positioned due to the engagement of said member in a corresponding recess in the plate. Then, the mechanism bridge is engaged on all of the pivoting elements which precisely fixes the pivot axes of these pivoting elements in their final position.
  • the mechanism bridge is made in one piece with the jumper spring which cooperates with the pull tab to determine the stable axial positions of the rod of the control mechanism.
  • the recesses receiving said members of the pivoting elements of the control mechanism are holes made in the plate.
  • said pre-positioning member. that each pivoting element comprises consists of one end of an axial piece driven into said pivoting element; the other end of this axial part forms a pivoting pin without lateral play in a hole in the mechanism bridge.
  • the watch shown in the drawings comprises a movement frame containing a plate 1.
  • a control rod 2 which can be actuated manually, is rotatably mounted and axially movable in the frame. This control rod is used for setting the time of the watch, for correcting a date indicator (not shown) as well as for other functions which will not be indicated here in detail, as well as The mechanisms actuated by the control device will not be described in detail, these mechanisms being foreign to the invention.
  • the control mechanism of the watch shown comprises, in addition to the rod 2, a sliding pinion 19 carried by the rod 2 and an associated connecting mechanism having the function both of ensuring an axial movement transmission between the rod 2 and the pinion 19, and allow these two elements 2 and 19 to occupy three stable axial positions.
  • This connecting mechanism comprises a pull rod 3, articulated on a pin 4, and which carries a pin 5 engaged in a groove 6 of the rod 2.
  • the pull rod 3 further carries a pin 7 cooperating with one or the other of several notches 8 presented by the head 9a, of a spring forming a jumper 9.
  • the spring 9 constitutes a part of a part 90 comprising a sole 9b fixed to a metal frame (or grid) 10, overmolded in plastic material 11 forming a substrate for an electronic module (not shown) of the watch (fig. 2).
  • the grid 10 molded in the plastic 11 constitutes the plate 1 of the watch movement.
  • the fixing of the sole 9b of the spring 9 is ensured by screws 12, taking in pillars 13, driven into the grid 10.
  • a metal spacer 100 is interposed between the plate 1 and the sole 9b. Like the grid 10, the spacer 100 is molded into the plastic 11.
  • the control mechanism further comprises a rocker 14, articulated on a pin 15.
  • a rocker 14 articulated on a pin 15.
  • one end 14a of the rocker 14 engages in an annular groove in the sliding pinion 19 carried by the rod 2, this groove being delimited ted by two shoulders 2a and 2b that has the sliding pinion 19.
  • One end, opposite the pin 5, of the pull tab 3 cooperates with an edge provided with notches 140 of the rocker 14.
  • the latter has beyond the pin 15 , a date correcting lever 16, the latter being articulated on a pin 17 and carrying a pinion 18 intended to control a mechanism (not shown) for correcting the date indicator.
  • the sliding pinion 19 is engaged with the pinion 18, which makes it possible to drive the latter in rotation.
  • All of the pivoting elements of the control mechanism namely the pull tab 3, the rocker 14 and the date correcting lever 16, are interposed between the plate 1 and the part 90, whether this is part 9b of the latter for which is the rocker 14 and the lever 16, or an extension part 9c of said part 90 with regard to the pull tab 3, which keeps these different pivoting elements in place.
  • Each of the pins 4,15 and 17 has a coaxial head of cylindrical shape 4a, 15a and 17a respectively, engaging with play in a hole 20 of cylindrical shape formed in the plate 1 from the face of this latter facing towards the pivoting elements 3,14 and 16.
  • the holes 20 provided in the plate 1 are used, during assembly of the watch, to pre-position the various pivoting elements 3, 14 and 16 of the control mechanism.
  • the part 90 serves as a pivot bearing for these pivoting elements, once the assembly of the watch has been completed.
  • the part forming the pull-rod jumper spring 90 not only keeps the pivoting elements 3, 14 and 16 of the watch control mechanism in place but, moreover, ensures their pivoting.
  • the heads 4a, 15a, 17a of the pins 4, 15, 17 are first placed, on which the pull tab 3, the lever 14 and the lever 16, respectively, have been driven into the holes 20 correspondents in plate 1 so that the pull tab, the rocker and the correcting lever are approximately in place on the plate.
  • the pull rod spring part 90 is then put in place, the pins 4, 15 and 17 engaging in the corresponding holes 20 of said part 90. This engagement is facilitated by the fact that the ends of the pins are chamfered, as indicated at 21 in fig. 3, in the case of the pin 17.
  • the pivoting elements of the control mechanism are thus brought into their exact position in which they will be held by tightening the screws 12.
  • the plate 1 partially made of plastic material may be other than a metal grid molded in plastic material.
