Definitions

  • the present invention relates to watches and in particular to mechanical wristwatches with a retrograde minute display.
  • a watch can display the time, it must have at least one device for displaying the hour and one device for displaying the individual minutes of the hour.

  • clocks with electronic clockwork which have a time display in the form of rotating hands.
  • the combination of digital liquid crystal displays and mechanical time display devices is also known.
  • mechanical clocks also use a mechanical display of the time.
  • three hands can be fastened in the middle of an arbitrarily shaped clock face so as to be rotatable about a single common axis of rotation.
  • a pointer serves to display the seconds, with both the minute hand and the hour hand moving gradually or step-by-step synchronously with the movement of the second hand when a minute or an hour has ended.
  • one revolution of the second hand by 360 ° corresponds generally to one minute
  • one revolution of the minute hand by 360 ° corresponds to one hour.
  • the mutual synchronization of the individual hands is brought about by the mechanical clockwork which drives the individual hands.
  • clocks are also known in which the axes of rotation of the individual hands are arranged decentrally on the dial. This leads on the one hand to an increased clarity of the dial and on the other hand to the possibility of individually positioning the three driven axes for the second, minute or hour hand in the dial compared to the previously described watch type.
  • the object of the present invention is to create a clock which combines increased clarity of the dial with technical freedom of design.
  • the invention is based on the knowledge that show the time by means of a mechanical clock is not necessary to use only rotating devices.
  • a retrograde minute display is used, which means that the minute hand only sweeps over a certain area of the clock face. As a result, the minute hand does not sweep the rest of the face of the dial, which leads to increased clarity of the dial.
  • a second hand or another functionality of the watch can be arranged, in which case it need not be taken into account that, for example, the heights of the second hand and the minute hand have to be coordinated so that they align do not interfere with each other when operating the watch.
  • This feature can also be used, for example, to reduce the overall height of the watch.
  • the watch developer thus obtains more technical degrees of freedom through the inventive concept of a retrograde minute display in order to adapt the desired goals and requirements of the mechanical watch to one another.
  • FIG. 1 shows a top view of a wristwatch according to the present invention.
  • Fig. 2 is a schematic plan view of the wristwatch, in which the hands have been omitted for clarity and the hour disc is visible.
  • 1 and 2 show a mechanical wristwatch with a retrograde minute display.
  • a minute hand 14 is fastened so as to be rotatable about a minute hand axis 16.
  • there is a minute scale 18 near the outer edge of the dial which ranges from 0 to 60.
  • a window 20 in the dial 12 Centered around the connecting line between the minute hand axis 16 and the number 30 of the minute scale 18 is a window 20 in the dial 12.
  • the window 20 is square, but it is obvious to those skilled in the art that it is also any other, such as can take a circular or elliptical shape.

  • the hour disc 22 has 12 segments on its edge, in each of which there is a number from 1 to 12 corresponding to the hour to be displayed.
  • the hour disc 22 is fastened rotatably about an hour axis 24, wherein according to the preferred embodiment of the present invention the hour axis 24 is positioned on the line between the minute hand axis 16 and the center of the window 20.
  • the second hand axis 26 is also located on this line, but on the other side of the minute hand axis 16.
  • a second hand 28 is fastened about the second hand axis 26 and points during its rotation through 360 ° to a second scale 30 corresponding to the second to be displayed.

  • the dial 12 is divided in its symmetry in such a way that the connecting line between the three axes 16, 24 and 26 halves the window 20 and the minute scale 18 and the second scale 30.
  • This line and the line connecting the two ends of the minute scale 18 and containing the minute hand axis 16 divide the circular dial 12 into four quadrants of equal size.
  • the minute scale 18 extends over 180 ° of the circumference of the dial 12 in the upper two quadrants. For the invention, however, it is immaterial how large is the area over which the minute scale 18 extends as long as it is arranged around the minute hand axis 16.

  • the placement of the window 20 on the clock face is not limited to the example described, since it is obvious that for a correct display of the time only the relationship of the window to the position of the hourglass 22 is essential, which is why the window 20 also elsewhere can be placed as long as the hour disc 22 is arranged accordingly.
  • a mechanical movement (not shown) drives the second hand 26 as well as the minute hand 14 and the hour disc 22 in such a way that the minute hand advances by one increment every 60 seconds, the hour disc again jumping by one segment after 60 minutes.
  • the minute hand 14 does not rotate 360 ° around the entire dial 12. Instead, the minute hand 14 moves from the left position, which corresponds to the minute 0, to the right position of the minute scale 18, the corresponds to the minute 60, after which the same jumps back to its original state to the minute 0 of the minute scale 18.
  • the hour disc 22 advances by one segment. This forward movement of the minute hand 14 and the jumping back of the minute hand 14 after 60 minutes (that is, after 180 ° of the circumference of the dial) causes the minute hand 14 not to sweep the lower area of the dial 12 since, as already explained, it does not pass 360 ° revolves, but only sweeps over a certain angular segment of the dial 12.
  • the area of the dial 12 over which the minute scale 18 extends can be smaller or larger than the 180 ° of the preferred exemplary embodiment.
  • the minute scale can also be arranged on another or several other squares of the dial, for example on the two lower ones.
  • the application of the present invention is not limited to wristwatches, since other clocks can also be equipped with a retrograde minute display.
  • the retrograde minute display and the jumping hour display are controlled by a mechanical watch drive.
  • the same can also from an electronic Clockwork can be controlled, in which case there must be a mechanical-electrical interface between the electronic control and the described display.

Abstract

L'invention concerne une montre (10), notamment une montre-bracelet mécanique comprenant un affichage rétrograde des minutes (14, 16, 18) et un affichage à chiffres sauteurs des heures (20, 22, 24). Cette montre comprend en outre un affichage des secondes (26, 28, 30) décentré, situé en dehors de la zone de l'affichage rétrograde des minutes (14, 16, 18). L'affichage rétrograde des minutes (14, 16, 18) s'étend sur 180° du cadran (12) de la montre.
