Definitions

• the present invention relates to a date display device with a window for a watch, the window being arranged along the axis 12 h - 6 h or close to this axis, as well as a method of activating the device display.
• the object of the present invention is to propose a display device making it possible to display in a window located on the axis 12 pm - 6 am or in its immediate vicinity the dates 1 to 31 centered in the window and using relatively figures great.
• the device according to the invention is characterized in that it comprises a first and second superimposed discs of identical and concentric dimensions of which at least the upper disc is made of a transparent material, that the first disc is divided by thirteen virtual rays in as many identical sectors and it includes near its periphery the numbers 1 to 9 located on nine consecutive virtual rays, the numbers 1 and 2 to the left of two consecutive virtual rays and the numbers 30 and 31 whose numbers are located on either side of the last two virtual rays, that the second disc is divided by eleven virtual rays into as many identical sectors and it includes near its periphery the numbers 0 to 9 located to the right of the ten consecutive virtual rays, the region of the eleventh virtual ray carrying no inscription, and that the display device comprises means arranged to drive the two disq ues so as to successively display the dates from 1 to 31 centered in the window.
• the advantage of this device is that instead of dividing the peripheral part of a disc to 31 equal parts in which we should be able to arrange the numbers 1 to 31 so that they are centered on the space that will be displayed behind the window, two superimposed discs are used, one of which is transparent comprising thirteen sectors, while the other has eleven sectors, which makes it possible to use relatively large numbers.
• two superimposed discs are used, one of which is transparent comprising thirteen sectors, while the other has eleven sectors, which makes it possible to use relatively large numbers.
• the arrangement of the figures in relation to the virtual departments makes it possible to obtain centering of the display.
• the transparent disc is made of glass or sapphire or any other transparent material.
• the means which drive the discs are mechanical means.
• the means controlling the drive of the discs are electronic means. Indeed, it is easy in electronic watches to provide a microprocessor controlling the rotation of each of the discs according to the date to be displayed. Finally, the invention relates to a method for activating said device, characterized by the following steps:
• the first disc is arranged so as to display the number 1 located on the virtual shelf, while the second disc is opposite the counter with the region without inscription,
• the first disc rotates in 24-hour periods of 1 / 13th of a turn to successively display the numbers 2 to 9,
• the first disc rotates 1/13 of a turn to display the number 1 located to the left of the virtual department and simultaneously the second disc rotates 1/11 to display the number 0 of the first ten,
• the first disk rotates 1 / I3 th round to display the number 2 located left of the virtual ray and the second disk rotates 2 / ll th to return to 0 and then it rotates every 24 hours l / llth turn to display units 1 to 9, f. then the first disc rotates 1/13 of a turn to display the number 30, while the first disc rotates 1/3 of a turn to return to the position without writing and then the first disc rotates 1/3 to display the number 31,
• the first disc rotates 1/13 th of a turn to display the number 1 located on the virtual department, and the cycle begins again.
• Figure 1 shows schematically a wristwatch with a display with large numbers which is located on the axis 12h - 6h.
• Figure 2 is a schematic representation of the first disc.
• Figure 3 is a schematic representation of the second disc.
• a watch 1 having the usual elements and a window 2 for displaying the date located on the periphery of the bezel and on the axis 12h - 6h.
• the window can be slightly shifted to the left or right or be located at the bottom, so close to the number 6, also centered or shifted slightly to the left or right.
• the device is composed (see FIGS. 2 and 3) of a first disc 3 and of a second disc 5 whose diameters are identical and are mounted coaxially in the watch case.
• the disc located near the dial which can be either disc 3 or 5, must be made of a transparent material, for example glass or sapphire or any other transparent material.
• the other disc could also be made of a transparent material, but this is not essential.
• the first disc 3 is divided by virtual departments 4 into thirteen equal parts.
• the numbers 1 to 9 are printed on a peripheral zone of the disc 3 centered with respect to the virtual departments 4.
• the numbers 1 and 2 are printed in consecutive spaces, but slightly offset from the virtual shelves, these two numbers will constitute the tens for the dates starting with 1, respectively 2.
• the remaining part includes the numbers 30 and 31 whose numbers 3 0 and 3 1 are arranged with on either side of the virtual shelves. In this way, the numbers 1 to 9 will be exactly centered in the window 2, as well as the numbers 30 and 31. Concerning the dates between 10 and 29, the display will be explained later when we have also described the presentation from the second disc.
• the second disc 5 identical in dimensions to the first disc 3 is divided into eleven equal parts by eleven virtual departments 6.
• the numbers 0 to 9 are written to the right of the virtual departments in nine consecutive positions and these figures will constitute the units for the dates between 10 and 29.
• the eleventh region corresponding to the virtual ray referenced 7 does not carry any inscription. This part of the disc 5 will be located opposite the window 2 when the numbers 1 to 9 illustrating the dates 1 to 9 will also be located opposite the window, which will make it possible to have a presentation centered in said window.
• the means for driving these two discs according to the actuation method which will be described thereafter are either purely mechanical means, or means controlled by electronic means.
• the two discs are arranged so that 1 in the window displays the number 1 and the part of the second disc without writing.
• the first disc 3 is moved 1 / 13th of a turn eight consecutive times per 24-hour period to display in the window 2 the dates 1 to 9.
• the second disc 5 remains stationary.
• the first disc 3 is moved by 1/13 and turns around to display the number 1 representing the first ten, while the second disc 5 is moved by l / ll th of turn to display the unit number, in this case 0.
• the second disc 5 is moved l / llth turn to obtain the successive display of the dates 11 to 19 and during this time, the first disc 3 remains stationary.
• the first disc 3 is moved by l / l3 th turn to display in the window the number 2 representing the ten dates starting with two, while the second disc 5 is moved 2 / l3 th for displaying the number 0 appears in the window.
• the first disc 3 remains stationary, while the second disc moves one / llth turn to successively display the units of the dates starting with 2.
• the first disc moves d 'l / l3 th turn and the second disc of l / ll th to return to the neutral position.
• the first disc still moves 1/13 , so all the dates are displayed.
• the first disc moves by 1/13 th
• the second moves by l / llth so as to return to the date 1 which will be centered also in window 2.
• the cycle starts again in the same way.
• Means, of course, are provided for moving the disc when the month does not contain 31 days.
• the advantage therefore of this display device is the fact that one can display in a window located on the midday - 6 o'clock axis or near this axis the dates with relatively large numbers and centered in the window.
