Definitions

  • the present invention relates to an analog display device according to a path chosen beforehand.
  • the analog display device is usually in the form of an additional module cooperating with an existing caliber.
  • the device or module has the particularity of modifying the indication of the minutes on the dial. Indeed, the minute indication hand moves along a route or a railway defined beforehand and printed on the dial.
  • the device according to the invention comprising a member for indicating a value to be displayed mounted on an axis of rotation, is characterized in that it comprises means arranged to control the indication member so that its free end follows the path chosen according to the rotation around the axis.
  • control means of the indication member can comprise a longitudinal groove sliding on two pins mounted on a guide arm, itself secured to the axis of rotation.
  • the means for controlling the indication member may include a transverse groove guided by a pin mounted on an arm in kinematic connection with the guide arm.
  • control means of the indication member comprise a pinion comprising a partial toothing causing with a toothing placed inside a recess made in the indication member and extending the longitudinal groove.
  • the teeth may include two opposite parts placed on either side of the recess, the pinion causing one after the other the two opposite parts of the teeth and thus causing a back and forth movement of the organ d indication of the value to display.
  • the member for indicating the value to be displayed is a needle.
  • the analog display device according to a previously chosen path is usually mounted on a timepiece.
  • the device can be used for the indication of any value specific to all fields of technology, such as temperature indication, voltage or electric current indication, size, capacity indication, etc. ...
  • the drawing shows, by way of example, several embodiments of the analog display device according to the invention.
  • Figure 1 In Figure 1 is shown a conventional watch 1 where the minute hand 2 travels in a circular motion. The free end of the needle 2 thus traverses a circle 3, so as to follow the path or railway of the minutes appearing on the dial.
  • the free end or tip of the minute hand 4 travels along an oval 5 which represents the chosen path or railway printed on the dial 6. It is obvious for those skilled in the art that the minute hand 4 is shown by way of example, and that this hand 4 could be the hour hand, or the second hand, or even an element for indicating any other data, for example day, month, year, etc. ...
  • the needle 4 shown in bottom view in FIG. 3 has two grooves 7 and 8.
  • the groove 7 can have a configuration chosen according to the path that the end of the needle 4 is supposed to make and the groove 8 is a longitudinal groove along the axis of the needle.
  • the needle 4 is driven by an additional device or module mounted on a timepiece, not shown.
  • the additional device or module which will be described later with reference to FIG. 6, comprises two arms 9 and 10 (FIG. 4) assembled one on the other at the center of the movement of the timepiece.
  • the arm 9 performs one complete rotation per hour and is integral with the mechanism for indicating the time of the timepiece, and the arm 10 is also driven by the mechanism for indicating the time, so as to effect two full turns per hour.
  • Pins 11, 12 and 13 are driven out of arms 9 and 10, and needle 4 is placed on arms 9 and 10, so that groove 7 coincides with pin 13, groove 8 being positioned by pins 11 and 12.
  • the groove 8 makes it possible to guide the minute hand and make them perform one revolution in one hour.
  • the pin 13 driven out of the arm 10 makes it possible to guide the needle 4 by making it pass through an ovoid.
  • the path of the needle 4 on the dial is defined by the speed of rotation of the arm 10 relative to the arm 9, and by the shape of the groove 7.
  • the latter makes it possible to refine the curve of the path of the railway, according to the shape given to this groove. It can be straight or curved.
  • the arm 10 rotates twice as fast as the arm 9, because we want the needle to be larger at noon and at six o'clock, and that it is smaller at three o'clock and at nine o'clock.
  • the mechanism for controlling the needle 4 in FIGS. 3 to 5 is shown in section in FIG. 6.
  • the indicator hand 4 in our case minute hand, is positioned at the very top of the stack of the mechanism of FIG. 6.
  • a wheel 14 is integral with the roadway of the base caliber 15, and therefore rotates one revolution per hour .
  • the pinion 16 and the wheel 17 form a reference which makes it possible to multiply the speed of the wheel 18a. In our case, two turns per hour for an oval.
  • On the latter is driven the arm 9 which drives the needle 4.
  • the arm 10 which rotates twice an hour we installed a simple return 18 between the wheels 14 and 19. Therefore, the arm No. 3 makes two revolutions per hour.
  • the hour hand is driven onto the hour wheel 19.
  • the mechanism which has just been described is mounted on a plate 20 which comes to rest on the base caliber or the timepiece.
  • the needle 4 can have different shapes, for example the shape shown in FIG. 7.
  • the shape of the needle will be determined by the stress caused by the presence of the means necessary for controlling the needle, in particular the two grooves 7 and 8 ( Figure 5).
  • the route made by the free end of the needle can also be chosen according to artistic or practical criteria of adaptation to the shape of the timepiece.
  • the path of the free end of the needle shown in Figure 8 is an example.
  • the arm 10 (FIG. 5) rotates three times faster than the arm 9.
  • the arm 10 performs four complete rotations for one rotation performed by the arm 9.
  • the example in FIG. 10 can be applied to the production of a square watch, as can the example in FIG. 9 for which it suffices to provide a 45 ° rotation for the entire device in relation to the timepiece.
  • the second embodiment of the analog display device shown in FIGS. 11 to 14 comprises a dial 21 on which a previously chosen path or railway 22 is printed.
  • the railway 22 appears under shape of an oval.
  • the display member 23 can be an hour, minute, second hand, or any other indication.
  • the two pins 26 and 27 intended to guide the needle 23.
  • the latter has inside its toothing 24.
  • the pinion 28 placed in the center of the gauge has a partial toothing 29. It rotates in the direction schedule causing with the toothing 24 of the needle 23.
  • the path of the needle is defined by the rack 24 used.
  • the device described can also be rotated 360 ° relative to the basic rating.
