Definitions

• the present invention relates to a time device with analog display, comprising a time dial and rotating hands driven by a clock system.
• a time device with analog display comprising a time dial and rotating hands driven by a clock system.
• the hands rotate counterclockwise (from left to right in the upper part of the dial and from right to left in the lower part of the dial).
• the hours, when they are written on the hourly dial, are written in numbers progressing in the direction of rotation of the hands, the number twelve being written at the top of the dial.
• the subject of the present invention is a time device of the analog display type which is better suited to people practicing writing. ture 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 device with a minimum of modifications to the clock system.
• the hours are written on the dial in numbers, characters or other symbols representative of numbers, going in a counterclockwise direction. , and the needles are rotated counterclockwise.
• the hours are written on the time dial in numbers, characters or other symbols corresponding to those commonly used by the people for whom the time device according to the invention is intended. .
• FIG. 1 represents a wristwatch in accordance with the invention with an hourly dial on which the hours are written in literary Arabic numerals
• FIG. 2 represents a wristwatch on which the hours are written in Chinese or Japanese numbers in handwriting
• FIG. 3 represents a wristwatch on which the hours are written in Hebrew letters in handwriting
• FIG. 4 represents an alarm clock with a dial devoid of any characters or other symbols indicating the hours
• FIG. 5 schematically represents a possibility for driving the needles in the counterclockwise direction
• FIG. 6 represents the electrical diagram of a quartz watch with rotation of the hands in a trigonometric direction.
• the wristwatch according to FIG. 1 comprises an hourly dial on which the hours (one to twelve) are written in literary Arabic numerals, so as to progress in the counterclockwise direction (opposite direction of the normal direction of rotation of the hands of a watch ), the number twelve being usually entered at the top of the dial.
• the hour, minute and second hands turn counterclockwise, i.e. counterclockwise as usual, as indicated by arrows.
• the time marked by the watch according to Figure 1 corresponds to two hours minus ten minutes.
• the wristwatch according to FIG. 2 includes a time dial on which the hours are written in Chinese or Japanese numbers in handwriting, so as to progress, just like on the watch in FIG. 1, in the counterclockwise direction, the number twelve being inscribed at the top of the dial.
• the wristwatch according to FIG. 3 includes a time dial on which the hours are written in Hebrew letters in block letters, these letters representative of the numbers one to twelve also progressing in the trigonometric direction, the letter representative of the number twelve being placed at the top of the dial.
• Figure 4 shows an alarm clock on which the hour, minute and second hands also rotate counterclockwise.
• the hourly dial of this alarm clock is devoid of any inscription representative of the hours.
• the use of a time device of this type will be conceivable when the dial time devices bearing inscriptions representative of the hours according to FIGS. 1, 2 and 3 have been used long enough for the users to have adopted and consider the meaning normal. trigonometric rotation of the hands and can therefore do without any hour representative inscription on the dial.
• the addition of such an additional pinion leads to an inversion of the direction of rotation of the toothed drive wheel 3 of the needles with respect to a usual time device.
• FIG. 6 provision is made, in the case of a time device with an electronic clock system, whose electronic circuit 4 powered by a battery 5 is adjusted by a quartz oscillator 6, to reverse, with respect to a usual time device, the polarity of the pulses applied from the motor 7 for driving the hands, by providing an inverter stage 8 upstream of the motor 7.
• the inscriptions representative of the hours can also be done in other printing, or in ideograms in the case of Chinese and Japanese inscriptions.
• time device can be of any type (wristwatch, alarm clock, clock, etc.).
