Definitions

  • the present invention relates to the field of watchmaking. It relates more particularly to a timepiece in which the hourly information display is produced using an endless ribbon rotating around the movement inside the box, the indications carried by this ribbon appearing through the ice.
  • a watch of this type is described, for example, in the patent CH 338 150 .
  • a mechanical movement of the classic type is surmounted by a U-shaped stirrup whose base is traversed by the roadway. This drives two vertical wheels mounted pivoting in the branches of the caliper and rotating at speeds whose ratio is that of the angular speeds of the traditional clockwise. These two wheels are respectively engaged with the teeth that have two endless ribbons arranged next to each other, around the movement and bearing one the indications of minutes, the other indications of hours.
  • Such a construction however suffers from two main disadvantages. Firstly, the power and the energy of the spring contained in the barrel may be insufficient to drive the ribbon for an acceptable duration. Second, the watch is very thick since it consists of the stack of a movement, the ribbon drive mechanism and sufficient space to allow it to go around the assembly.
  • the object of the present invention is to provide a timepiece with a ribbon display that is free of these two disadvantages.
  • the timepiece is of the type comprising an endless flexible tape bearing hourly indications and stretched between two parallel rollers, and a mechanism for rotating at least one of these rollers, comprising a spring wound inside a cylinder, an exhaust and a regulator coupled to the exhaust.
  • This piece is characterized in that the spring is wound inside the roller which thus constitutes the barrel of the drive mechanism.
  • the two rollers are identical and constitute barrels which are coupled in identical ways, via a gear train, a single exhaust and a regulating member located halfway between the two.
  • FIG. 1 shows, at 10, an endless flexible tape stretched between two parallel identical rollers 11 and 12 driven simultaneously in rotation by a mechanism which will be described later in detail. When rotating, these rollers move the tape counter-clockwise, one or more full rotations per day.
  • the flexible tape 10 may be of silk, metal, plastic, paper or any other material. It presents side by side, arranged perpendicularly to the rollers and made by printing, a scale 13 bearing the indications of the hours from 0 to 11 and possibly a scale 14 carrying, in front of the space separating two indications of successive hours, indications of minutes. In this case, the ribbon rotates and 12 hours. Good Of course, the scale 13 can also carry the indications of the hours from 0 to 23 , in which case the ribbon rotates in 24 hours.
  • the rollers 11 and 12 which serve to drive the ribbon 10 are themselves the energy source of the movement, that is to say that they constitute the barrels and therefore each contain a spring whose relaxation, over time, ensures their rotation and, thus, the movement of the ribbon.
  • rollers at their ends may be advantageous to provide the rollers at their ends with teeth engaged with openings along the edges of the ribbon, like those of a photographic film.
  • the ribbon drive is thus made safer.
  • the teeth of the rollers must be mounted frictionally thereon.
  • the distance between the two rollers 11 and 12 is 21.99 mm, while their diameter is 7 mm.
  • the rollers 11 and 12 must therefore, under the action of their respective springs, respectively perform 3.35 or 6.7 rounds per day.
  • the length of the rollers allows them to form barrels with a spring having, because of its high height, a moment of maximum force exceptionally higher than that of the spring of a conventional barrel. If a single high-pitch spring is not available, it suffices, for example, to couple side by side, on the bung of the barrels, several elementary springs of conventional movements. which makes it easy to reach a moment of maximum force of 20 Nmm for each of them.
  • the ribbon drive even if it is relatively heavy, no longer poses any problem in terms of power and energy. A power reserve greater than 48 hours is thus offered.
  • each roller 11 and 12 which rotates in the counterclockwise direction, is pivotally mounted between two bridges 17 and 18. It ends with a barrel wheel 19 engaged with the pinion. a wheel of high average 20 whose wheel is engaged with the pinion of a wheel of small average 21 whose wheel is engaged with the pinion of a second wheel 22.
  • the two second wheels 22 mesh, halfway between the two rollers, with the pinion 23 of an escape wheel 24 also rotating in the anti-clockwise direction and conventionally coupled by an anchor 25, to a balance spring 26 forming a regulating member.
  • the axis of the escape pinion 23 is offset with respect to the line AA joining the axes of the two barrels on which are aligned the axes of the mobiles 20 , 21 and 22. All these mobiles are pivotally mounted between two bridges 27 and 28.
  • each roller 11 and 12 ends with a ratchet 29 meshing, halfway between the two rollers, through two referrals 30 and 31, with a central winding pinion 32 disposed on the line AA along which are aligned the axes of the mobiles 30 and 31.
  • the latter are pivotally mounted between a bridge 33 and the bridge 18 used by the rollers.
  • the bridges 17, 18, 27, 28 and 33 are advantageously assembled using a system of rods (not shown) constituting, in a way, the platen of the movement.
  • FIGS 5 and 6 show, by way of example, the manner in which the winding and setting functions of this movement are performed.
  • the winding pinion 32 belongs to a central winding rod 34, parallel to the axes of the rollers 11 and 12, operable in rotation and in translation by means of a ring 35 and mounted between the bridges 18 and 33. It carries a pinion 36 which, in the pushed position of the rod 34, shown in Figure 5, is inactive. In this case, the pinion 32 is, as in Figure 2, in engagement with the two ratchets 29. The rotation of the ring 35 then allows the winding of the springs of the two barrels 11 and 12.
  • Figure 7 shows, by way of example, the possibility of using a ribbon 10 displaying the time zones.
  • a fixed line 40 then serves as a reference for reading hours.
  • the timepiece according to the invention can use only one of the rollers as barrel.
