  • Such a mechanism 1 is typically integrated into a watch movement, for example into a timepiece such as a pocket watch, a wristwatch, a clock or a clock.
  • the date disc 1051 typically an annular disc, comprises a scale 1061 comprising thirty-one indications, corresponding to the dates of the months, uniformly distributed over a circumference of its upper surface. These indications are arranged in increasing order in the opposite direction to the direction of rotation of the date disc 1051, that is to say in the counterclockwise direction and are intended to move opposite an aperture 107 typically made in a dial of a timepiece in which the display mechanism 1 is integrated.

  • the assembly comprising said actuating mechanism 108 and actuating means constitutes the "control means" of display mechanism 1.
  • the rocker 101 Independently of the actuating pinion 108a, the rocker 101 carries a driving wheel set 1031 comprising a first toothed wheel 1031a with sixty teeth and a second toothed wheel 1031b with six coaxial teeth, these wheels being integral in rotation with each other and free in rotation around the axis A1.
  • the first 1031a of the toothed wheels of this drive wheel set 1031 is kinematically connected to the going train of the watch movement in which the display mechanism 1 is integrated so that the two wheels 1031a, 1031b of this wheel set typically perform a sixth of a turn. every 24 hours.
  • the second 1031b of the toothed wheels of this driving wheel set 1031 meshes with the internal toothing of the date ring 1021. It takes one step every 24 hours and makes said ring 1021 pivot by one step every 24 hours, thus date display from one indication to the next each day.
  • the first 1031a of the wheels of said mobile 1031 meshes with the day wheel 1022 which is carried by the rocker 101.
  • This day wheel 1022 is rotatable about an axis of rotation A2 distinct from the axis A1 and typically parallel to this axis A1, the axis A2 being fixed with respect to the rocker 101 and mobile in rotation with respect to the plate 100.
  • the gear ratio between this day wheel 1022 and the second wheel 1031b of the mobile drive such that this day wheel 1022 is rotated at a rate of one-seventh of a revolution per day.
  • the actuating mechanism 108 When actuated, the actuating mechanism 108 makes it possible to pivot the rocker 101 between two extreme positions, alternately from a first to a second extreme position then from said second extreme position to said first extreme position.
  • the figures 2a to 2c illustrate the transition from the first of said extreme positions to the second of said extreme positions when the actuating mechanism 108 is actuated via the actuating means.
  • the figure 2b represents an intermediate position between said two extreme positions.
  • rocker 101 The two extreme positions taken by rocker 101 during operation of display mechanism 1 define its angular travel. In this example, it is approximately 30°. These extreme positions are reached at each alternation of the direction of rotation of the flip-flop 101.
  • the display mechanism 1 is designed so that the relative position of rocker 101 with respect to plate 100 impacts neither the rotation of the day disc 1052 nor that of the date disc 1051. Indeed, the position of the center of rotation A1 is fixed during the pivotings of the rocker 101 so that the first wheel 1031a of the mobile drive 1031 can be driven in rotation by continuously by the going train.
  • the second wheel 1031b of the driving wheel set 1031 being integral with it, it is permanently able to drive the date disc 1051 in rotation.
  • the day wheel 1022 and its axis of rotation A2 move with the rocker 101, this wheel 1022 therefore meshes with the first toothed wheel 1031a whatever the position of the rocker 101.

  • the display mechanism 1 operates in a dragging manner but it could easily be modified to operate instantaneously (by jumps), that is to say typically in milliseconds.
  • the drive wheel set 1031 could comprise an additional six-tooth star coaxial and integral in rotation with the first 1031a and second 1031b toothed wheels of the drive set 1031, this star wheel being driven in instantaneous rotation by one step every 24 hours. under the effect of a finger carried by a rocker bearing a feeler, said feeler being held against a snail connected kinematically to the going train of the watch movement in which said display mechanism 1 is integrated and dropping suddenly every 24 hours.
  • the actuating means is typically designed to allow the display of the day of the week at choice when it is held down or when it is held pulled.
  • the actuating means can be designed to return automatically to its initial position or can, on the contrary, remain blocked in the position that the user has just imposed on it until it does not activate it again.
  • actuating means could be other than a rack rod as described previously.
  • this rack rod could for example be replaced by a connecting rod system.
  • a connecting rod system would typically comprise a rod, one end of which would be accessible from outside the watch case and the other end of which would pivot freely around a pin fixed eccentrically to the actuating wheel 108b of the actuating mechanism 108 so as to drive the latter in rotation in one direction and then in the other during its back and forth movements.
  • the rack rod could be replaced by a rod, one end of which would be accessible from outside the watch case and the other end of which would be fixed to a first end of a spring cable wound around the axis of rotation of the actuating wheel 108b.
  • the second end of this spring cable would be fixed to said axis of rotation so that the to-and-fro movements of said rod would cause wheel 108b to rotate alternately in one direction then in the other.
  • Such a display mechanism 1 has the advantage of allowing the display of two different pieces of information alternately in the same window, the user being able, simply by acting on an actuating means, to control the flip-flop 101 to choose the information (date or day of the week) that he wishes to be able to read through the window 107. This allows, while offering the user the possibility of obtaining information on different information, not to overload the dial with multiple counters.
