Definitions
- Chronographs and chronograph watches have so far been produced in many forms which differ from each other mainly by the mode of presentation of the control and display members, the materials used, the appearance, etc.
- These timepieces generally comprise a so-called second hand driven with a period of one revolution per minute, and which can be stopped at will to read the timed time.
- the dial has divisions marking sub-periods corresponding to seconds. The sub-period fractions can be read approximately to the fifth of a second if the balance-spring system oscillates at 18,000 vibrations. For optical reasons, higher reading accuracy is hardly possible, even with timepieces having a frequency higher than the usual frequency.
- the chronograph comprises, in addition to the second hand indicating the number of seconds passed, counters, for example a minute or hour counter, totaling the minutes or the hours passed.
- a disc-shaped hour mobile surmounting the dial also has five concentric circular areas on each of which are distributed twelve equidistant slots, so as to obtain 60 equal circular sectors, each of the slots on a defined range being offset from the nearest slot. located on the adjacent beach (s) at an angle of 6 °.
- the arrangement of the device makes it possible to read, clockwise, coincidences separated by 65.45 seconds from each other. To obtain separate coincidences of 60 seconds, the hour mobile should be trained with a period of one revolution in eleven hours, which would distort the reading of the hours.
- the object of the present invention is to eliminate the drawbacks which the known devices present, more particularly in an adaptation of the vernier principle to allow a precise and easy reading of the fractions of sub-periods clockwise or counterclockwise, independently of the direction of rotation of the mobile indicator and requiring, at the user, no knowledge of said principle of vernier.
- fig. 4, 5, 6 are similar views of the organs of a reading pair according to the second variant of the first embodiment
- fig. 7a is a schematic sectional view of a chronograph using one or the other of the variants of the first embodiment
- FIGS. 14, 15, 16 are views similar to FIGS. 8, 9, 10, showing a third variant of the second embodiment and
- the indicating device is incorporated into an analog chronograph with mechanical movement which is shown diagrammatically in FIG. 7a.
- the visible upper face of this chronograph comprises a circular dial on which is mounted a flange 16 which can be seen in FIG. 1, the marking consisting of a crown 1 centered on the axis of the needles, of constant width over its entire periphery.
- the dark crown 1 has an alternation of light and dark ranges which divide the arc of the circle from 11 a.m. to 1 a.m. into 10 pairs of alternately dark and light elements ( 2).
- the ratio between the widths of the ranges of each pair gradually varies from one end to the other of the arc of a circle. The details of this arrangement will be described later in connection with FIG. 7b.
- Figs. 8 to 19 are partial views which illustrate a second and a third embodiment of the device. This is applied to a chronograph equipped with one or more counters, this or one of these counters being provided for counting tenths of seconds while the second hand normally moves above the dial.
- the tenths counter can be placed in any of the four usual positions: 3 a.m., 6 a.m., 9 a.m. or 12 p.m.
- Figs. 8, 11 and 14 show the marking of the reading member, FIGS. 9, 12 and 15 that of the display member and FIGS. 10, 13 and 16 the superposition of the two bodies, this in the first, second and third variants of the second embodiment.
- the transparent spaces drawn radially on the mobile disc must extend over a defined angular distance: the latter must in fact be at most equal, from on the one hand, at the angular distance covered by the movable disc in 1 / N th of a sub-period and, on the other hand, at the step of progression (1 / N) of the light or dark areas on the disc of the fixed member presenting a division of N sub-periods.
- N 10
- FIGS. 8 to 16 allow a succession of coincidences clockwise regardless of the direction of rotation of the mobile.
- This characteristic is interesting when the tenth of a second is read on a separate counter. Indeed, depending on the construction, the system for returning from the central seconds hand to the mobile for reading fractions of sub-periods, the direction of rotation of the latter can be counterclockwise, in which case it will then be necessary to add a mobile .
- the aforementioned characteristic of the invention precisely makes it possible to avoid such addition and, consequently, all the drawbacks that it would entail for the device (increases in cost, size and energy consumption).
- an indicator device as described above can be integrated into a standard watch with or without a second hand for the sole purpose of creating an evolving decorative effect.
