Definitions

  • the present invention relates to a date display device for a timepiece, comprising two indicator discs arranged side by side, one bearing the numbers of the units, the other those of the tens, the two numbers side by side. the two respective disks appearing in a window arranged through a dial indicating the time.
  • the object of the present invention is to provide a solution capable of remedying, at least partially, the aforementioned drawbacks.
  • this invention relates to a timepiece display device for a timepiece according to claim 1.
  • the skilled person does not need to know the drive mechanism of the display device, the latter being a date device of the type called "big date” quite conventional well known to those skilled in the art. Thanks to this mechanism, the disk of the units is driven one step every day and that of the tens a step every ten days.
  • the passage of the 28, 29, 30 or 31 to the 1 of the following month will be done automatically by a known mechanism which neutralizes the disk of the units if the month has 31 days and only trains the tens, or drives the two discs one step if the month has 30 days. If it is a perpetual mechanism, he will make the correction also for the month of February. Finally if it is a simple calendar, the correction is done by hand, each time the month is less than 31 days.
  • the display device therefore comprises two disks side by side, a disk of the units 1 carrying the numbers from 0 to 9 and a tens disk 2 carrying at least a series of four digits 0 to 3, the 0 can be replaced by a blank space or by a decorative element.
  • the tens disk has two sets of numbers from 0 to 3, which allows it to approach the number of digits of the disk units and thus make two disks having substantially the same diameter.
  • These two discs 1, 2 are transparent, the numbers they carry being of a color, for example black, as usual. Only the parts of these disks 1, 2 located inside the window which is represented by a rectangle 3 in the drawing are visible to the observer, so that the drive mechanism of these disks 1, 2 can be located Almost outside the field of view of the window 3. Under these parts of the disks 1, 2 and preferably a little beyond to take into account the parallax, the surface which appears through these parts of the transparent disks 1, 2 is a color contrasting with that of the numbers carried by these discs, for example, if the numbers are black, the surface that appears through the discs 1, 2 will be white or at least clear. Since the disks are transparent, their respective edges are almost invisible, so that it is no longer necessary to separate the wicket 3 in two by a median cross to hide the edges of the disks 1, 2.
  • the surface underlying the disks 1, 2 appearing in transparency in the aperture 3 can be formed on a wafer 4 fixed to the frame, generally to the turntable of the timepiece by screws 4a.
  • the wafer 4 can be omitted and the contrasting surface intended to appear under the portions of the disks 1, 2 located in the window 3 can be directly formed on the plate by total or partial coating thereof of the desired contrasting color. If the tests carried out showed that the white background and the black numbers give good results, one can also consider doing the opposite, white figures on a black background. However, this solution seems less favorable at first glance.
  • the transparent discs produce a reflection, it may be advantageous to choose a bright contrasting color to attenuate the difference between the portions of the background surface 4 that are covered by the discs 1, 2 and the areas 4a of the same surface. bottom located between the disks 1, 2 and which are not covered by them.
  • the transparent discs 1, 2 can be made of plastic or glass. In the case where they are made of plastic, they could be obtained by injection by positioning figures made for example by cutting, in the injection mold, so that they are at least partially embedded in the plastic injected . These figures could have a certain thickness, for example corresponding to the thickness of the transparent disk 1, 2, which would give them a particular relief, still unknown so far since we would then see the slice of these figures, since they are embedded in a transparent disk.
