    Description: [0001] The invention belongs to the field of watches and other timepieces. More particularly, the invention relates to a watch or timepiece with an analogue display of the hour by means of a lens, this display being linear, bidirectional with automatic change of scale as a function of the direction of rotation. movement of the lens.
    It is in the context of mechanical watches become luxury item and therefore subject to many forms of execution that is this new embodiment that uses a belt to transform the rotary movement of the caliber and a linear movement.
    The idea of using a chain or belt in the field of watchmaking is still not widespread. US5199006 discloses a solution using a continuously rotating tape on which the indicator is attached. DE 20 216 628 discloses a linear display solution with back and forth and double scales. WO 2004 006 026 discloses a solution using belts to transmit motion and / or torque between two pulleys. The brand Martynov & Cetinkoprulu offers a watch equipped with two rotating loupes.
    The object of the invention is to provide a mechanical watch with a marker following a bidirectional linear path and having an automatic scale change at each change of direction of the movement of the marker, the marker may be a needle, a lens or an indicator directing the gaze of the observer to the point of the scale corresponding to the time of the moment.
    [0005] Judiciously, a micro-belt will be used as the carrier of the marker, micro-belt being taken in the general sense which implies the flexible traction means such as simple belts, notched or drilled, chains, cables, ropes etc. produced in closed or open loop with connection. The axes of rotation of the drive pulleys are perpendicular to the plane of the display.
    The bidirectional trajectory of the belt is generated by a direction switching mechanism realized by means of a gear set controlled by a lever. An additional device with double cams ensures an almost instantaneous passage from one direction of movement to the other. This same device also makes it possible to change the scale indicating the time according to the direction of movement of the belt.
    [0007] A particular attachment of the lens to a single belt or to two parallel belts makes it possible to increase the linear path of the lens that can go from one edge to the other of the housing.
    A magnifying effect of the lens can be arranged by introducing a convex shape this to improve reading.
    In addition, a judicious arrangement of background colors, signs and the lens increases the apparent contrast of reading signs placed under the lens relative to other signs.
    The figures below represent, without limitation, an embodiment example:
    Fig. 1 shows the watch as a whole with the ladder on the left and the descending ladder on the right.
    Fig. 2 shows drive belts of the lens.
    Fig. 3 shows a solution with chain or belt holes.
    Fig. 4 has a mechanism for reversing the direction of rotation.
    Fig. 5 shows a belt drive.
    Fig. 6 shows a cam switching device.
    Fig. 7 shows a switching mechanism in its 2 working positions.
    Fig. 8 presents a set of the mechanism.
    Fig. 9 shows a section of the mechanism.
    Fig. 10 presents a watch with complementary displays
    Figs. 11 shows a variant with 2 visible belts and marking hours of high contrast Realization of the invention [0011] Below is described a mode or an embodiment of the invention.
    FIG. 1 shows the watch in a set with its case (1), the winder (2) the dial (3) with on the left, the ladder (4) which indicates digits from 0 to 12 with the lens (5) on position 8 while on the right, the scale is descending (6) with numbers ranging from 12 to 00 and the lens (5) is positioned on 21.
    FIG. 2 shows a device for driving the lens (5). It consists of two micro-belts (7, 8) and a tightening rectangle (9) of the lens. The production of micro-belts whose sectional dimensions are of the order of 0.2 to 0.5 mm is a major aspect for the realization of this watch. Judiciously, we will start from a plate of a particularly reliable and stable material such as block copolymer elastomers. The plate is then cut on the edge with the help of a high-precision femto-laser. All 2 belts and the rectangle tightening of the lens are thus produced from the same plate. The pulleys (10, 11) have the synchronization notches of the belts.
    Fig. 3 shows a solution made with a microchannel (51) and a marker having the shape of a needle point (52) or with a chain formed of a cable with crimped spheres (53), mesh having the form of spheres concentric (54) or belt or perforated strip (55) driven by a toothed pulley (56), said band being of open type. It is closed by means of a connection independent or integral with the lens to be driven (57).
    FIG. 4 shows a reversing direction of rotation with gears represented by circles. On the left, the lever (12) having its point of rotation on the axis of the driven wheel (13) is pulled to the right by the roller (14). Thus, the driving wheel (15) actuates the intermediate wheel (16) which meshes the driven wheel (13) in the same direction as the driving wheel (15). In the image on the right, the roller pulls the lever (12) to the left which has the effect of detaching the coupling of the intermediate wheel (16) in favor of the other intermediate wheel (17) which acts on the driven wheel (13) through the wheel (18), ie the direction of rotation of the driven wheel (13) is reversed.
    FIG. 5 shows the drive device of the belts with the axes of the hens perpendicular to the plane of the display. It consists of the reverser of direction of rotation whose driven wheel (13) is coupled with the pulley (10) driving the right belt (8), the latter acting on the pulley (11) which at its turn and through the gear wheels (19, 20, 21 and 22) drives the second belt synchronously. Note that it is possible to fix or cut the rectangle holding the lens (9) by a small central segment (23) rather than a band, thus obtaining a path of the lens that is approaching greatly the edge (24) of the dial, this to the extent that the diameters of the wheels of the inverter are adapted to this configuration.
    FIG. 6 shows the mechanism of change of direction of the belts. On the left, the driving wheel (25) is actuated by the counting mechanism and rotates at a rate of one revolution per 24 hours. This same wheel (25) drives through the pin (27) the cam (26) called break cam which has the same center of rotation as the driving wheel (25). Thus, during 12 hours, the rotation of the cam has the effect of loading the spring (29) then, when its end (30) reaches the breaking edge, the cam will turn sharply until the end ( 30) falls on the new lower part of the cam thus generating a sudden advance of ten degrees, this advance being possible due to the bleeding (28) operated in the rupture cam. On the right, we add an additional cam (30) called a cam movement on the cam (26). This second cam is integral with the rupture cam. In addition, a rod (34) held by four sliders (33) can move horizontally. This rod has 2 pins (31, 32) which rub on the edge of the cam (30). Thus, when the rupture cam advances abruptly by ten degrees, the motion cam also rotates at the same angle, which has the effect of moving the rod from the right to the left through the ankles (31, 32) and vice versa. 12 hours later.
    FIG. 7 shows the same mechanism with the two time scales that have been placed on a ladder support plate (35) itself attached to the rod (34). On the left, it is the rising scale (4) from 0 to 12 hours which is in the center of the device whereas on the right, one is located immediately after a rupture which has the effect of moving the tables to the left and thus to see the descending ladder (6) from 12 to 24 hours be at the center of the device for the next 12 hours.
    FIG. 8 shows the entire device with the integration of the direction reverser and the rupture device which spontaneously moves the rod (34) support tables. This rod (34) has an additional pin (36) which drives the lever (12) for controlling the direction of rotation. Thus, every 12 hours, it is simultaneously the tables (4, 6) that change position and the direction of movement of the lens which is reversed.
    FIG. 9 shows the watch in section with its various components including the housing (1), the winding (2), the window (38), the counting movement of time (36), the counting wheel of time (25), the breaking cam (26), the pulling pin of the breaking cam (27), the spring (29) acting on the breaking cam (26), the movement cam (30, the movement pins (31), the slides (33), the rod (34) and its ladder support plate (35) and the lens (5).
    FIG. 10 shows a watch with its linear hour display (41) by means of the lens (42) completed by an indicator of the direction of travel of the lens (43) and two complementary displays, one for the minutes (44). ) and the other for seconds (45) or universal time.
    Figs. 11 shows a variant with two visible belts (46) and marking hours with high contrast. This last technical effect is obtained by using, for the background color of the dial (47), a first color (a), while the signs (48) are of a second color (b) and the indication of time made by means of the lens (9) itself of a third color (c). The colors (a, b, c) being chosen so as to increase the apparent contrast in reading the signs placed under the lens (49) relative to the other signs (48), this phenomenon being added, if necessary, to the magnifying effect that gives a lens.
