Definitions

  • the present invention relates to a character display mechanism for a timepiece comprising an indicator member arranged under a mask and arranged to rotate stepwise about an axis perpendicular to the mask, the indicator member carrying a series of entangled figures. distributed on a circular track, the mask having a display area having a plurality of openings.
  • the figures being intended to appear successively through the openings of the mask during the rotation of the indicator member, and the openings being arranged so as to show only one figure at a time in the display area.
  • Most of the known character display mechanisms for timepieces comprise the combination of a window, that is to say an opening of dimensions corresponding to those of the indications to be displayed, practiced in the dial of the room. watchmaking, and a rotating disk which carries a series of indications to display, these indications being written next to each other on a circular track passing under the window when the indicator member rotates.
  • This display system is used very generally, for example in calendar watches. It is also used for example in mechanical watches at hours jumping, in which a disc replaces the hour hand so that a number is displayed in a window and then disappears as soon as we move on to the next hour.
  • the digital display at jumping hours requires the rotation of a disk containing the series of 12 or 24 numbers to display. It makes it possible to obtain static figures unlike the digital continuous display.
  • a defect shared by most display mechanisms that meet the description given above is the small size of the displayed indications. Indeed, to avoid overlap between neighboring indications, the different indications must be contained each in a separate sector of the indicator disc. Under these conditions, it will be understood that the opening of a sector is limited to the angle obtained by dividing 360 ° by the number of indications distributed around the disk. In the case, for example, where the indications are the sequence of the numbers from 1 to 31, it can be calculated that the opening of the sectors is a little less than 12 °.
  • the patent document CH 589 881 in particular describes a digital display mechanism which is in accordance with the definition given in the preamble.
  • This mechanism conventionally comprises a disc arranged to turn step by step under a fixed dial.
  • the disk has at its periphery numbers or pairs of numbers intended to be displayed successively in a window arranged in the dial.
  • a peculiarity of this known display mechanism is that the numbers plotted on the disk encroach on each other because of their large size.
  • the window of this known display mechanism is constituted by a mask having a series of openings distributed over a plot that corresponds to the superposition of the numbers to be displayed successively.
  • An object of the present invention is to further increase the size of the indications that can be displayed using a character display mechanism for a timepiece.
  • the present invention accomplishes this purpose by providing a character display mechanism according to the appended claim 1.
  • the mechanism of the invention is arranged to display each character or group of characters using one of the figures carried by the first indicator member.
  • some of the figures carried by the first indicator member are associated with second openings through the first indicator member.
  • the mechanism of the invention can complete a figure carried by the first indicator member by adding to this figure one or more segments carried by the second indicator member.
  • this same figure can be used to display several different characters.
  • it is therefore possible to display all the characters or groups of characters to be displayed with a smaller number of figures.
  • An advantage of having fewer figures to be distributed on the circular track of the first indicator member is that it is possible to further increase the size of each figure.
  • the three indicator members are represented in angular positions corresponding to the indication of the number "24".
  • the figure 1 is a top plan view of the dial of a timepiece equipped with a jumping hour display mechanism according to a first embodiment of the invention.
  • timepieces of this type include a digital display instead of the usual hour hand.
  • openings referenced 7A to 7G and 9B and 9C
  • the openings in the display area consist of rectilinear segments which are nine in number and which together form a representation of the number "18".
  • the number "18" corresponds to the superposition of the plots of all the numbers from "1" to "12” as represented in the present example.
  • the seven segments referenced 7A to 7G together form an "8", and that the last two segments, referenced 9B and 9C, form a "1".
  • the display mechanism described can each represent digits from “0” to “9” using segments 7A to 7G, and that the mechanism uses the two segments 9B and 9C to represent the number "1".
  • the display principle that has just been described is known per se. It falls into the category of so-called 7-segment displays.
  • the 7-segment displays form all digits from “0” to "9” using a subset drawn from seven straight segments (four vertical segments and three horizontal segments).
  • the jumping hour display mechanism of the present example comprises a first and a second indicator member arranged under the dial and arranged to rotate stepwise about an axis perpendicular to the dial.
  • These two indicator organs are respectively the subject of the views in plan from above.
  • Figures 2A and 2B The reporting bodies Figures 2A and 2B are provided to be arranged in a superimposed position in the jumping hour display mechanism, the first indicator member extending between the dial 3 and the second indicator member.
  • the first indicator member has an irregularly rendered contour by the presence of cutouts (referenced 13a and 13b). It will be admitted however that, apart from these cuts, the general shape of the indicator has a rotation symmetry of order 8. It can be seen further that the indicator organ carries a series of eight figures which are distributed, concentrically to the axis of rotation, on a wide circular path. It will be noted that the figures overlap each other, and that two overlapping figures are inclined relative to one another. Finally, it should be noted that, in the illustrated example, the figures carried by the first indicator are drawn of a dark color on a white background, and that the mask is also white.
  • the apertures in the aperture are oriented in such a way that two figures can overlap without appearing simultaneously through the mask.
  • the figures are arranged to intersect at the ends of the segments, or in other words, so as to intersect outside of the parts of the segments that are intended to appear in disguise. the openings of the mask.
  • two overlapping figures are inclined exactly 45 ° to each other.
  • the four vertical segments 7B, 7C, 7E and 7F and the three horizontal segments 7A, 7D and 7G of the 7-segment display are not inclined, but precisely make an angle between them. 90 °.
  • the first indicator member is pierced with a number of openings (hereinafter referred to as second openings).
  • second openings are of two kinds.
  • first holes referenced 11a, 11b and 11c
  • the holes 11a, 11b and 11c all have a shape identical to that of the first openings 7A to 7G and 9B, 9C pierced in the mask.
  • the holes can be considerably larger than those of the mask, since they are always at least partially hidden by it.
  • the cutouts 13a and 13b are larger than the openings of the mask.
  • the shape of the second indicator member has the same order of rotation symmetry 8 as that of the first indicator member. It can also be observed that the second indicator member bears a pattern made with the same dark color as the figures carried by the first indicator member. In addition, the pattern is also drawn on a white background. It can also be seen that the pattern comprises segments that are oriented in the same four directions (horizontal, vertical, oblique to the left, oblique to the right) as the segments that form the eight figures that carries the first indicator member.
  • the jumping hour display mechanism of the present example is adapted to display the sequence of numbers from “1" to "12" by means of an indicator member bearing a series of exactly eight figures and which is arranged to rotate by taking steps of 45 °.
  • the operation of this mechanism will now be described.
  • the angular positions in which the two indicator organs are represented in the Figures 2A and 2B are associated with the display of the number "1".
  • the figure carried by the first indicator member which is visible through the mask is formed of a single dark colored segment referenced 15. It will be understood that the color of this segment contrasts with that of the mask. The segment is clearly visible through the opening 7B of the mask.
  • the figures carried by the first indicator are drawn on a white background.
  • the mask and the background are of the same color, when a portion of white background is directly under an opening of the mask, its effect is to hide this opening. In the configuration shown, the first openings 9B and 9C of the mask are thus obscured.
  • the first indicator member also has second openings arranged to stop directly under one of said first openings during the stepwise rotation of the first indicator member.
  • three second openings are stopped directly under a first opening.
  • six of the first seven openings of the portion of the mask for displaying the units are directly superimposed on second openings.
  • the character display mechanism makes it possible to complete a figure carried by the first indicator member by adding to this figure one or more segments carried by the second indicator member.
  • the display mechanism makes it possible to indicate the number "1" by associating the segment 17 which is carried by the second display member in Figure 15 (ie the segment 15) which is carried by the first display member. It will be further understood that the segment 17 and the segment 15 together form a representation of the number "1".
  • the twelve Figures 3A to 3L illustrate how each number of the sequence of "1" to "12" appears successively in the display area of the dial 3, then disappears as soon as we move on to the next hour.
  • the figure 3A includes a first view reproducing the second indicator member as shown in FIG. Figure 2B , a second view reproducing the first indicator organ as represented in the Figure 2A and a third view reproducing the mask as represented in the Figure 2C .
  • the figure 3B is similar to the figure 3A . However, it represents the two indicator organs in a different configuration, which corresponds to the indication of the number "2".
  • the first indicator member being in the same angular position in the figure 3B that in the figure 3A the figure of the first indicator member which is visible through the opening 7B of the mask always corresponds to the dark colored segment referenced 15.
  • the parts of the first indicator which are visible through the first openings 9B and 9C of the white mask are background portions, also white. Under these conditions, the openings 9B and 9C are virtually invisible.
  • the first remaining openings (7A, 7C, 7D, 7E, 7F and 7G are each directly superimposed on one of the second openings 11a, 11b or 13a.
  • first openings 7C and 7F of the mask are obscured by the white background of the second indicator member.
  • the cutout 13a also extends below the surface occupied by the first openings 7C and 7F. These first two openings are thus obscured by the white background of the second indicator member.
  • the figure 3C is similar to Figures 3A and 3B . However, it represents the two indicator organs in a different configuration, which corresponds to the indication of the number "3". If we carefully observe the indicator organs represented in the Figures 3B and 3C it can be seen that the angular position of the first indicator organ does not change between the figure 3B and the figure 3C . On the other hand, we note that in the figure 3C , the second indicator member has undergone a new rotation of 45 ° in the clockwise direction relative to its angular position in the figure 3B . It will be understood that this rotation has the effect of substituting the indication of the number "3" to that of the number "2".
  • the first indicator member being in the same angular position in the figure 3C that in the figure 3B the figure of the first indicator member which is visible through the opening 7B of the mask always corresponds to the dark colored segment referenced 15.
  • the parts of the first indicator which are visible through the first openings 9B and 9C of the white mask are background portions, also white. Under these conditions, the openings 9B and 9C are virtually invisible.
  • the first remaining openings (7A, 7C, 7D, 7E, 7F and 7G are each directly superimposed on one of the second openings 11a, 11b or 13a.
  • first openings 7E and 7F of the mask are obscured by the white background of the second indicator member.
  • the cutout 13a also extends below the surface occupied by the first opening 7F and the second opening 11a extends below the first opening 7E. These first two openings are thus obscured by the white background of the second indicator member.
  • the new figure visible through the mask is formed by the four segments 35, 37, 39 and 41 which are respectively visible through the first openings 7B, 7C, 7F and 7G and together form the number 4. It will therefore be understood that the rotation of the first indicating organ has the effect of substituting the indication of the number '4' for that of the number '3'.
  • the portions of the first indicator which are visible through the first openings 7A, 7D, 7E and 9B of the white mask are white background portions. Under these conditions, these first openings are virtually invisible. Finally, the last first opening (referenced 9C) is superimposed on the second opening 13a. It will therefore be understood that the first opening 9C of the mask is obscured by the white background of the second indicator member.
  • the second indicator organ thus accomplishes only one half-turn per cycle of 12 hours. This is the reason why the pattern carried by the second indicator member has a rotation symmetry of order 2. However, it will be understood that alternatively, it could be used for example a second indicator member advancing step by step by jumps 90 °.
  • the figure 4 appended represents a jumping hour display mechanism according to a second embodiment of the invention.
  • a first difference between this embodiment and that which was the subject of the first example is that it is a 24-hour display instead of a 12-hour display.
