Abstract

TIME DEVICE WITH ANALOGUE DISPLAY, IN WHICH THE HOURS ARE REGISTERED ON THE TIME DIAL IN NUMBERS GOING IN THE TRIGONOMETRIC DIRECTION, AND THE HANDS TURN IN THE TRIGONOMETRIC DIRECTION. PREFERREDLY, THE HOURS ARE REGISTERED IN EASTERN ARAB NUMBERS. APPLICATION: TO PEOPLE PRACTICE RIGHT TO LEFT READING.

Description

Time Apparatus with Analog Display "The present invention relates to

  a timepiece with an analogue display, comprising a time dial and rotating needles driven by a clock system. On hourly devices (watches, clocks, etc.) known from the analog display type, the hands rotate in opposition to the trigonometric direction (from left to right in the upper part of the dial and from right to left on the lower part of the dial) . The hours, when they are written on the hour dial, are in figures going forward in the direction of rotation

  needles, the number twelve being written at the top of the dial.

  Although this arrangement is entirely satisfactory in reading and writing countries from left to right, this is not the case for countries that practice reading and writing from right to left. This is the case, for example, for Arabic writing and Hebrew writing, as well as for writing and reading Japanese numerals. People practicing this mode of reading and writing are thus hampered by the direction of rotation of the hands and by the direction of progression of the digits 25 representative of the hours on the dials of the apparatus

classic schedules.

  The subject of the present invention is a time device of the analog display type which is more suitable for people practicing writing and reading from right to left. The invention also relates to a time device of this type which can be produced on the basis of a usual time unit with a minimum of modification.

on the clock system.

  On the time apparatus according to the invention at 35 hour dial and with rotating needles driven by.

  a clock system, the hours are written on the dial in figures going forward in the direction

  trigonometric, and the needles are rotated in the counterclockwise direction.

  Preferably, on the apparatus according to the invention, the hours are written on the hour dial in figures.

  corresponding to those routinely used by the persons for whom the time apparatus according to the invention is intended, for example in Arabic Eastern numerals for nationals of the countries practicing the Arabic alphabet.

  With reference to the accompanying drawings, the object of the invention will be described in more detail below; on the

drawings-: - - -

  FIG. 1 represents a time device: according to the invention with a time dial on which the hours are written in Arabic numerals of the West; FIG. 2 represents a time device according to the invention on which the hours are written in figures.

Arabs of the East.

  The time apparatus according to Figure 1 comprises a time dial on which the hours (1 to 12) are written in Arabic numerals West progressing in the trigonometric direction (in the opposite direction of the normal direction of rotation of the clockwise) , the number 12 is registered in the usual way at the top of the dial. The hour and minute hands turn in the trigonometric sense, that is to say the opposite direction.

  usual watch, as indicated by an arrow. The time indicated by the watch according to FIG. 1 corresponds to two hours to ten minutes.

  The time apparatus according to FIG. 2 differs from the apparatus according to FIG. 1 only in that the hours are written in Arabic numerals of the Orient, the progression of the digits being the same as in FIG. 1 (trigonometrical direction) , as well as the direction of rotation of the needles, To drive the needles in the trigonometrical direction, it suffices, starting from a usual clock system designed for driving the needles in opposition to the trigonometrical direction, that is, that is to say in the usual clockwise direction to add an additional pinion between the output gear of this clock system and the toothed gear wheel of the needles. Indeed, as is well known, the addition of such a pinion

  This leads to a reversal of the direction of rotation of the drive gearwheel.

  In the case of a time machine with an electrical or electronic timekeeping system (for example a quartz oscillator clock system), it suffices to reverse the polarity on the driving member of the hands, for example by means of the prediction. an inverter stage upstream of the motor unit. It goes without saying that the embodiments described above and illustrated by the accompanying drawings have been given only as non-limiting examples and that many modifications and variants are possible in

the scope of the invention.

  Thus, according to the persons for whom the time apparatus according to the invention is intended, the hours can be entered in usual figures for the 25 persons in question, that is to say other figures.

  only Arabic numerals from the West or the East.

  It should also be noted that the time apparatus according to the invention can be of any

  type (wristwatch, alarm clock, clock, etc ...).
