Definitions
- the present invention generally relates to a display device digital information and more particularly such a display device for the indication of two-digit numerical information such as the date or last two digits of a year.
- a display device for the indication of two-digit numerical information such as the date or last two digits of a year.
- Such a device is more particularly intended for be integrated into a timepiece such as a wristwatch.
- Two-digit digital information displays used in wristwatches are mainly of two types.
- a first type comprises an annular disc bearing a series of numbers typically from 1 to 31, which correspond to the 31 calendar days of the month. The disc is driven one step a day by an appropriate mechanism and is visible through a window arranged in a dial.
- the downside to this type of this device is that the numbers, which are relatively small dimensions, are difficult to read.
- a second type of display device comprising two discs bearing the unit and tens figures respectively, these two discs being arranged either side by side or concentrically. These devices have a better readability, but are however bulky and their use in wristwatches limits the possibilities of equipping these wristwatches other types of displays.
- the main object of the present invention is to remedy the drawbacks of the aforementioned prior art by providing a display device for indication two-digit digital information that is simple and compact while retaining good aesthetics and good readability.
- the invention also aims to provide a display device for the indication of two-digit numerical information which can be easily integrated into small objects such as timepieces.
- the invention relates to a display device for indicating two-digit digital information, characterized in that it comprises a disc bearing a series of figures distributed regularly along its periphery, and in this that it further comprises first and second independent pointers, at least two of these three elements being movable in rotation, said pointers being arranged respectively outside and inside the periphery of the disc to indicate respectively the tens digit and the units digit of said information to pin up.
- the display device allows, thanks to the combination of two pointers and disk, display two-digit numeric information to using a single disc carrying a single series of numbers and this in a way original.
- the display device obtained is thus very compact.
- the series of figures includes the digits 0 to 9, the first pointer is fixed while the disc and the second pointer are rotatable around a common geometric axis.
- FIG. 1 we see a front view of a timepiece 1 with calendar, comprising, in addition to devices for displaying the day of the week, the date and month, a display device according to the invention indicating the two last figures of the year, designated by the general reference 2.
- the display device 2 comprises a disc 4 bearing a series of numbers from 0 to 9 distributed regularly along its periphery. According to the invention these figures will serve as will appear more clearly below to indicate both the units and the tens of the two-digit number to be heard pin up.
- the disc 4 moves in rotation above a dial 6 and is driven by any suitable conventional means.
- the disc 4 moves opposite a first pointer 8, fixed in the example illustrated.
- the pointer 8 is typically produced by a decal made on the dial or by an insert on it.
- the pointer 8 is arranged outside the periphery of the disc 4, according to a axis noon-six o'clock from disc 4 and noon.
- Pointer 8 indicates in this mode realization, and by convention, the digit of tens of digital information to two digits you want to display. According to a variant, it is understood that the fixed pointer 8 could be located anywhere along the periphery of the disc 4.
- the disc 4 includes a central recess 10 which defines a ring at its periphery 12. Numerals 0 to 9 are applied at regular intervals on the surface of the crown 12.
- the disc 4 further comprises a central opening 14 for the passage of a 16 of a second pointer 18.
- the second pointer 18 is also mobile in rotation and moves relative to the disc 4 opposite the figures carried by this latest.
- the movable pointer 18 is arranged inside the periphery of the disc 4.
- the moving pointer 18 comprises a disc 20 on which is affixed an index 22. More precisely, the disc 20 has a diameter substantially lower than that of the recess 10 and is arranged in the latter.
- the disc 20 is connected to the drive shaft 16 which passes through the central opening 14 of the disc 4.
- the upper surfaces of the crown 12 and of the disc 20 are coplanar ( Figure 2).
- the pointer 18 indicates by the index 22 the number of information units two-digit numeric you want to display.
- the disc 4 is associated with first drive means (not shown) which increment it by one every ten years while the moving pointer 18 is associated with second drive means (not shown) which increment it of one unit every year.
- these drive means can be formed of a gear train driven by mechanical means or by a stepper motor controlled by a microprocessor programmed so appropriate.
- FIG. 3 there is shown by way of illustration three configurations of the device display according to the invention indicating the last two digits of the years 2008, 2009 and 2010.
- the fixed pointer 8 points towards the number of tens, or 0 while the moving pointer 18 points via the index 22 in the direction of the unit figure, ie the number 8.
- the disc 4 remained stationary so that the fixed pointer 8 always points towards 0, the tens figure has not changed.
- the moving pointer 18 has advanced one step in clockwise to point towards the number 9 representing the number of units.
- the fixed pointer 8 now points towards the number 1, that is, disc 4 has advanced one step counterclockwise to bring the fixed pointer 8 opposite the number 1 representing the tens digit, while index 22 of moving pointer 18 points towards the number 0.
- the display device can indicate a date.
- disc 4 is associated with first drive means (not shown) which increment it to bring the numbers 1, 2, 3 and 0 next to the fixed pointer 8, respectively at the end of the 9, 19, 29, 30 and if necessary 31st days, while the second pointer is associated with second training means (not represented) which increases it by one unit per day.
- FIG. 4 display according to the invention in several display configurations of two last digit of a calendar.
- the reading principle is the same as that described previously in connection with FIG. 3.
- the invention is of course not limited to the embodiment described above and different variant embodiments can be envisaged.
- it can be provided, according to a first variant, that the disc 4 is fixed and that the pointer 8 is carried by a member movable in rotation along the periphery of the disc 4.
- the pointer 18 is fixed, and that the pointer 8 and the disc 4 are both movable in rotation.
- the mobile pointers mentioned above and formed by discs may be replaced by needles or any other means of indication appropriate.
