Definitions

  • Chronographs of both analog and digital types are known in the art. This invention relates to a chronograph with an hour hand and a minute hand as well as a digital display according to the preamble of claim 1.
  • the date display is digital. It is also known to separate the loose digits of the days and the one-digits.
  • the CH 119 761 shows a clock in which the hour is displayed digitally in a window that moves with a movable disc that displays the minutes in an extension of the window via a display.
  • a clock having the features of the preamble of claim 1 is known from US-A-3,675,413 known.
  • Prior art chronographs have pointer displays.
  • a disadvantage of known chronographs with pointer displays is the poor readability of minutes and hours. This concerns in particular, the readability of an activity in which the wearer of the clock can not spend several seconds looking at his watch with focus on accurately reading graduations. This concerns, for example, motorists and airmen. Therefore, the preferred in particular of aviators watches are usually designed with a relatively large dial to increase the distance of graduations from each other and to increase the readability.
  • the invention has the object, a chronograph of the type mentioned in such a way that the stopped time is easy to read.
  • the advantage for the user is that he can read the minutes or hours directly digitally without using a partial line display. This allows a safe reading of a time recorded by the chronograph, even with vibration and the ability to throw only a moment on the dial.
  • the tens of minutes are separated from the entities.
  • the hour, Zehnerminuten- and minutes display back to the starting position, representation of the number zero.
  • the display is designed as a speed indicator, which counts down by an inverse gear ratio of a maximum adjustable speed.
  • a mechanism may be provided which does not act similar to a fly-back chronograph until the stuffing function is triggered, i. is stopped. At this time, a gear train is set in motion, which stops at the stopped time on the stop second. The display discs are thus not moved during the actual stop process, but tracked.
  • the energy for this tracking similar to the repetition, may come from an additional source of energy charged by a switching mechanism or the like, such as a pusher.
  • a predetermined amount of fluorescent material may be deposited on the framing of the display windows which provides sufficient light to illuminate the numerals of substantially highly reflective material disposed on the display slices indirectly against the background to let the panes shine.
  • the Fig. 1 shows in a schematic manner the dial of a chronograph according to the invention according to a first embodiment.
  • the hands of the hours and minutes of the clock are indicated by the reference numerals 2 and 3.
  • the second hand of the watch is laterally arranged as a retrograde second hand 4 and pivots over a range of 120 °. This range can correspond to a time lapse of 20 seconds, so that the resulting angular velocity is identical to the angular velocity of a rotating second hand.
  • the second hand 5 of the chronograph is arranged coaxially with the hour and minute hands 2, 3 of the watch. Also coaxial to these hands, discs 6, 7 and 8 are provided for minutes, ten minutes and hours of the chronograph.
  • the minute display on the disc may, for example, be arranged in two sequences from 0 to 9.
  • the ten-minute display can carry the numbers from 0 to 5 twice, or the numbers 0 to 6 or 0 to 9 for a tachymeter display.
  • the hour display goes from 0 to 9 and carries another symbol between 9 and 0.
  • a flag or other symbol indicates that the displayable time range has been exceeded and thus invalidates the display. It is displayed to the user in such a way that the chronograph has been running for more than 10 hours and does not provide any clear information for the elapsed time.
  • the hour display 8 can carry the numbers 0 to X instead of the numbers 0 to 9, and the said symbol is provided between X and 0, which then appears permanently as hours 8 after the expiration of X hours 59 minutes and 59 seconds in order to determine the expiry of the hour display the regular measuring range.
  • X may be greater than the single digit number be nine.
  • the display is done through the windows 9 in the immobile dial 1.
  • the windows 9 for hours and minutes can be contiguous or as separated in the figures by a bridge.
  • the numbers 6, 7, 8 can be the same size or the hour 8 can be chosen in particular slightly smaller than the number of minutes 6 or 7.
  • the chronograph is also designed as a tachymeter.
  • the display is controlled as a speed display, which counts down by an inverse gear ratio of a maximum adjustable speed.
  • a speedometer for example, in the first 4 seconds after the start of the chronograph, the number 900 (for 900 km / h) set to then be counted down accordingly in speed.
  • a changeover to a different pitch on a toothed disk can be provided on the stop second pipe.
  • a mechanism may be provided that does not act until the stuff function is triggered. At this time, a gear train is set in motion, which stops at the stopped time on the stop second. The display discs are thus not moved during the actual stop process, but tracked.
  • the Fig. 2 shows a second embodiment of the invention, in which it has been emphasized that the hour and minute hands 2 and 3 of the clock do not cover the display of the chronograph.
  • the same features are each provided with the same reference numerals.
  • the retrograde seconds display 4 of the clock is arranged outside the one-minute disk 6.
  • the second hand 5 of the chronograph is now arranged on a separate axle 11, which is located on the right inner edge within the hour hand (hour) 8 of the chronograph.
  • the axes 10 and 11 are disposed on opposite sides within the hourglass 8.
  • the axis 11 also forms the main axis of the movement.
  • the two hands 2 and 3 may consist only of a thin strand of material, such as e.g. Form carbon fiber that has been soaked to display in the dark with a matrix of epoxy resin and phosphor mixture. With such thin hands 2 and 3 for hours and minutes, only small portions of the numbers are covered, so that the number can still be easily recognized directly when reading.
  • a thin strand of material such as e.g. Form carbon fiber that has been soaked to display in the dark with a matrix of epoxy resin and phosphor mixture.
  • a device for displaying the digital digits in the dark may be provided.
  • a fluorescent substance For example, the digits stand out against this reason.
  • a garland of fluorescent material may be placed around the frame of the window 9 so that light from it will fall on the window surface. If then the numbers are essentially Made of a highly reflective material, they shine against the dark background of the discs.
  • a battery-based or accumulator-based light indicator can be provided.
