Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, a display device type "digital. "
  • Examples are the documents US 4,496,945 and DE 2707241 , which disclose conventional displays of the "seven-segment" display type, in which sliding elements appear at the back of wickets to form segments.
  • documents EP1906266 , CH698760 and CH592907 illustrate miniaturized variants of such displays.
  • the document CH592907 in particular discloses a well-rationalized embodiment, which has only three flip-flops pivotable about two axes of rotation under the control of three cam paths. These scales have boards with color ranges that appear selectively through slots in the dial.
  • the object of the invention is, therefore, to provide a digital display device, in which the appearance of the figures displayed is much more pronounced, and thus the visual attraction of the display is improved.
  • a first embodiment of the invention relates to a display device for a timepiece a plurality of segments, and a plurality of needles surmounting the dial.
  • Each of the segments is associated with at least one of said needles, each of the needles being arranged to pivot between a masking position, in which the needle is superimposed with a segment to hide it, and a free position, in which the needle is not superimposed with a segment, to leave it visible.
  • a control device is also provided, which is adapted to control each of the pivoting needles to selectively hide and leave the segments visible to display a series of alphanumeric characters, in particular digits, composed by at least one of the segments .
  • the segments have a contrasting appearance with respect to their background (dial or movement, if any), with respect to the color and / or gloss and / or finish of these elements.
  • the needles have a similar appearance or similar to their background, so as to hide the segments well.
  • the needles are each pivotally mounted about an axis corresponding substantially perpendicular to the plane of the display device, or even the base movement, which allows the use of common techniques in the watch industry for the construction of the device. display.
  • the plurality of segments comprises seven segments distributed as a seven-segment display, which is a readable display capable of representing the numbers 0 to 9, as well as a few letters.
  • the needles are grouped on three axes, two of these axes being arranged at a corner of the seven-segment display and each carrying a needle, the last axis being arranged halfway on a side of the seven-segment display with three hands.
  • a well-rationalized layout with a minimum of components is thus proposed.
  • each needle is arranged to mask a segment directly adjacent to the axis of the corresponding needle, and therefore not a distant or opposite segment of said axis.
  • the invention relates to a display device for a timepiece comprising at least one cover and a plurality of needles.
  • Each of these needles is arranged to move between a hidden position, in which the needle is hidden by said cover and therefore between the dial and the cover, and a visible position, in which the needle is not hidden by said hidden.
  • the display device also comprises a control device adapted to control the selective pivoting of each of the needles between its hidden position and its visible position in order to display a series of alphanumeric characters, in particular numbers, composed by at least one one of the needles.
  • the needles have a contrasting appearance with respect to the dial or the visible elements of the movement with regard to the color and / or the brightness and / or the finish of these elements.
  • the cover has an appearance identical or similar to the dial or the visible elements of the movement, to make it hardly distinguishable for the user.
  • the needles are each pivotally mounted about an axis corresponding substantially perpendicular to the plane of the display device, which allows the use of common techniques in the watch industry for the construction of the display device.
  • the plurality of needles comprises seven hands distributed as a seven-segment display which is a very readable display capable of representing the numbers 0 to 9, as well as a few letters.
  • the needles are grouped on three axes, two of these axes being arranged at a corner of the seven-segment display and each carrying two needles, the last axis being arranged halfway on one side of the seven-way display. segments and carrying three needles.
  • a well-streamlined arrangement with a minimum of components is thus proposed for the second embodiment.
  • the figure 1 illustrates a seven segment display element 1 according to a first embodiment.
  • This display element 1 consists of seven segments 3a-g located at a number "8" on the visible surface of a dial 5, and thus forming a seven-segment display in a conventional manner.
  • These segments 3a-g may be formed by colored areas, metallized, printed, or the like on the surface of the dial 5. They may also be formed by elements protruding from the surface of the dial 5.
  • the segments 3a-g contrast with the rest of the dial 5, in color and / or gloss so that they are clearly distinguishable from the latter.
  • the dial 5 is not mandatory, and the segments 3a-g can be mounted "floating" above the frame of a skeleton watch, supported for example by rods connecting them to the frame.
  • Each segment 3a-g is associated with a needle 7a-e, which each serves as a cache for at least one of the segments 3a-g.
  • These needles 7a-e are arranged to pivot about the corresponding axes of rotation 9a-c, substantially perpendicular to the dial 5 (and thus also perpendicular to the plane of the display device 110 and to the plane of the base movement), under the control of a control device 200 located below the dial 5 (see schematically on the figure 2 ).
  • the needles 7a-e thus evolve each between a masking position in which the needle 7a-e is superimposed on a segment 3a-g to mask it, and a free position, in which the needle 7a-e is not in superposition of a segment 3a-g, to leave it visible.
  • the needles 7a and 7d are in masking position in superposition of the segments 3c and 3e respectively, the needles 7b, 7c, 7e being in free position, between the segments and superimposed with parts of the dial 5 with which they have no or little contrast. These needles thus leave the segments 3a, 3b, 3d, 3f and 3g appear in order to dial the number "5".
  • the concepts of "no or little contrast”, “identical or similar” on one side and “contrast”, “contrast” on the other side can also be interpreted relatively to each other, ie to say that the first concepts indicate less contrast than the second concepts.
  • the needles 7a-e are arranged to pivot at an angle of 45 ° or 135 ° between its free positions, either directed towards the inside of the display element 10, or outwards , and at least one masking position. Other angles of rotation are naturally possible.
  • the needles 7a-e have a similar appearance, even identical to the dial 5, so that they have little contrast with the dial 5 or elements of movement (wheels, frame etc.) visible below the needles 7a-e in the case of a skeleton watch, and are thus difficult to distinguish from this background.
  • the dial 5 (or the elements of the movement) and the needles 7a-e may have substantially the same color and / or substantially the same finish. Therefore, the needles 7a-e mask the segment (s) corresponding (s) when they are ordered in superposition, making them almost invisible to the user. It should be noted that in figures 1 and 2 this contrast has not been reproduced to make needles 7a-e clearer. Nevertheless, the contrast ratios have been well represented on the figures 3a and 3b .
  • five needles 7a-e are distributed over three rotation axes 9a-c, at several levels (two levels in this case), as is clearly visible in FIGS. figures 3a and 3b , so that they do not encroach on each other during their angular movements.
  • the axes of rotation 9a-c are positioned on two end corners of the same long side of the number "8" and on the midpoint of the other long side of the number "8".
  • the two axes of rotation 9a, 9b located on the corners each carry a needle 7a, 7e, serving as a cover for the segments 3a, 3c and 3f, 3g respectively. So for these needles 7a, 7e, each needle serves as a cache for two segments. That located on the mid-point on the other side of the number "8” carries three needles 7b, 7c, 7d, pivotable independently of one another, which serve as a cover for segments 3b, 3d and 3e respectively.
  • needle arrangements 7a-e are naturally possible.
  • an axis of rotation could be arranged at each corner of the number and at each midpoint on the long side of the number "8", each axis bearing one or two needles, if any.
  • Other possibilities could also be considered.
  • the figure 2 illustrates this principle applied to a 12-hour display 100, in the hour indication state 12:55.
  • This display 100 comprises three elements display 1 to seven segments, and a display element 1a arranged to display either nothing or the number "1" for tens of hours.
  • the display element 1a comprises only two segments and two needles, and simply takes up the characteristics of the long side to the right of the number "8" in the other display elements 1.
  • the 24-hour display one can simply provide a set of four display elements 1, each with seven segments.
  • the figure 2 also schematically illustrates a control device arranged to control the pivoting of the needles 7a-g.
  • This control device 200 may be entirely mechanical, comprising for example an arrangement of cams or cam tracks arranged to rotate the needles 7a-g.
  • the control device 200 may be electromechanical, comprising, for example microprocessor-controlled step motors.
  • the figures 3a and 3b illustrate the sequence of operation to display the series of numbers 0-1-2-3-4-5-6-7-8-9, the contrast between the segments 3a-g, the dial 5 and the needles 7a-e having been correctly represented.
  • the reference signs have been reproduced only in the drawing on the left at the top of the figure.
  • figure 3a in which the display element 1 displays the digit "0".
  • the various positions occupied by the needles 7a-e, as well as their angular positions to display the various figures are clearly visible on the figures 3a , 3b and should not be described in detail, particularly in view of the fact that they flow unambiguously from figures 3a and 3b , and that those skilled in the art can vary them without departing from the scope of the invention.
  • the figure 4 illustrates a seven segment display element 10 according to a second embodiment.
  • This second embodiment applies the same principle as the first, but in the opposite direction: the dial 5 is not provided with segments 3a-g, and the numbers are composed of seven needles 13a-g in their visible positions, the needles having a contrast with respect to the dial 5 with regard to the colors and / or the brilliancy of these components.
  • the dial 5 is not mandatory and the needles can simply be visible above the frame of a skeleton watch. In such a case, the needles thus have a contrast with the mechanism and the frame as visible by the user.
  • the display element 10 is provided with at least one cover 11, arranged to hide the needles 13a-g when they should not be visible and so are in their hidden positions.
  • This cover 11 has little contrast with the background of the hands, that is to say with respect to the dial 5 or with respect to the visible elements of the movement (wheels, frame, etc.), for example by presenting exactly the same color and / or the same finish of the dial 5, or a color and / or finish similar to the frame and / or the workings.
  • the finish of the dial 5 has not been illustrated, to make appear more clearly the cache 11.
  • the contrast ratios have been well represented on the Figures 6a and 6b .
  • the concepts of "no or little contrast”, “identical or similar” on one side and “contrast”, “contrast” on the other side can also be interpreted relatively to each other, that is to say that the first concepts indicate less contrast than the second concepts.
  • the axes of rotation of the needles 9a-c are positioned in the same manner as for the first embodiment shown in FIG. figure 1 , and the needles 13a-g are spread over several levels (two levels in this case). Nevertheless, the axes of rotation 9a, 9b located on the extreme corners of the number "8" on the long side to the right are each provided with two needles 13a, 13c and 13f, 13g respectively.
  • the cover 11 is diagonally between the axes of rotation 9a and 9c, and between the axes 9c and 9b.
  • covers 11 are also possible, for example covers extending from the axes of rotation 9a-c towards the outside of the number "8", or a cache 11 surrounding each digit "8" which has a width sufficient to hide the needles when rotated below the cache.
  • the figure 5 illustrates the principle of the second embodiment applied to a 12-hour display 110, in the state of time indication 12:58.
  • This display 110 comprises three seven-needle display elements 13a-c and a display element 10a arranged to display either nothing or the number "1" for the tens of hours.
  • the display element 10a comprises only two needles, and simply takes up the characteristics of the long side to the right of the number "8" in the other display elements 10.
  • a display element 10a can be provided with only the needles 13a, 13c, 13d, 13e and one of the 13f and 13g, or alternatively one could simply provide a set of four display elements 10, each to seven needles.
  • the figure 5 also schematically illustrates a control device arranged to control the pivoting of the needles 13a-g.
  • this control device 200 may be entirely mechanical, comprising for example an arrangement of cams or cam tracks arranged to rotate the needles 7a-g.
  • the control device 200 may be electromechanical, comprising, for example microprocessor-controlled step motors.
  • FIGs 6a and 6b illustrate the sequence of operation of the second embodiment to display the series of numbers 0-1-2-3-4-5-6-7-8-9, the contrast between the hands 13a-g, the dial 5 and the caches 11 having been correctly represented.
  • the cover 11 of the display element 10 for the minutes units has been removed in order to reveal the position of the hands 13a-g regardless of whether they are in their hidden position or their free position.
  • screws 11a which serve to secure the covers 11 with the dial 5.
  • the needle 13f and, if necessary the needle 13c is (are) hidden (s) below the needles 13g and 13a respectively to limit the number of levels on which the needles 13a-g are located: indeed, the needles 13b, 13d and 13e are already below the cover 11, and a greater number of levels should be provided for the needles if the needles 13c and 13f were to hide below the cover 11 at the same time as the needles 13b, 13d and 13e.
  • this explanation does not exclude the possibility that the skilled person would arrange the needles in this way.
  • needles 7a-g and 13a-g can be arranged in a number of different ways, on combinations of various levels.
  • the covers 11 may be formed according to the wishes of those skilled in the art, and may even be formed by an additional partially transparent dial in superposition of the needles 7a-g or 13a-g.
  • the same principle also applies to a display capable of displaying several letters, or even the complete alphabet, by arranging a greater number of axes, needles, caches, segments, etc., the case applicable.
