Definitions

  • the present invention relates to the field of watchmaking. It concerns, more particularly, a wristwatch movement comprising a chronograph mechanism provided with a display member of a timed unit of time, associated with a first catch-up mechanism of said timed time unit.
  • the catch-up mechanisms are well known to those skilled in the art. In general, they are implemented on chronograph mechanisms and generally allow to measure the second of an intermediate time, displayed by means of a split second hand. During a measurement, the split-second needle moves in synchronism with the chronograph second hand, being hidden beneath it. By actuating the split-second mechanism, the split-second hand comes to a stop, while the timed time measurement continues. After reading the split time, the split second hand can "catch up" with the chronograph second hand and come under the chronograph second hand and both continue moving in synchronism.
  • a split wheel 10 is coaxially mounted and free to rotate relative to a wheel of the chronograph mechanism, usually the chronograph second wheel, not visible in the drawing.
  • a jumper core 14 is arranged coaxially and is integrally with the chronograph wheel.
  • the split wheel 10 carries a lever 16, one end of which is supported on the core 14 by a spring 18. The support of the lever 16 on the core 14 makes it possible to index the relative positions of the split-seconds and chronograph wheels.
  • a locking mechanism 20 of the split wheel is provided and is controlled by the user when he wants to read an intermediate time.
  • the most known locking mechanism is a clamp The opening and closing of the clamp releases, respectively, blocks, the rotation of the split-second wheel 10.
  • a needle is secured to the chronograph wheel and another is integral with the split wheel 10.
  • the split-seconds pliers are open. Thanks to the support of the lever 16 on the split core 14 and a suitable adjustment of the position of the hands, the chronograph hand and the split-seconds are superimposed and move in synchronism, so that the user has the impression of seeing only one needle.
  • the user By actuating the locking mechanism 20, the user causes the locking of the split-seconds wheel 10 by the clamp.
  • the split-second needle is immobilized, but the split-second core 14 continues to rotate with the chronograph wheel, the lever 16 sliding on the edge of the heart 14. The user can then read an intermediate time, without interrupting the measurement.
  • the display members of said chronograph mechanism and said first and second catch-up mechanisms being intended to carry indexes located on the same side of the movement.
  • the display members are arranged coaxially.
  • one of the first and second splitters is located on one side of the movement, the other of the first and second splitters being on the other side of the movement.
  • the chronograph mechanism and the first catch-up mechanism are arranged on the bottom side of the movement, the second catch-up mechanism is arranged on the side of the movement dial.
  • the display member of the chronograph mechanism is a first tube
  • the display member of the first split-second mechanism is disposed inside said tube and is capable of receiving an index
  • the display member of the second catch-up mechanism is a second tube, the first tube being disposed inside the second tube.
  • the invention also relates to a wristwatch equipped with a movement according to the invention. It comprises a first, a second, a third and a fourth push button for operating the chronograph mechanism and the first and second catch-up mechanisms.
  • these push buttons are arranged in pairs, symmetrically with respect to the axes 9hours-3hours and 12hours-6hours of the watch.
  • the display members of the chronograph mechanism and the first and second catch-up mechanisms each receive a needle.
  • These needles are arranged so that the needle of the first split-second mechanism is located above the chronograph hand and the needle of the second split-second mechanism is located below the chronograph hand, the top of the watch being located on the side of the display.
  • the watch illustrated on the figure 2 has a second hand 30 for displaying the second timed, driven directly by a second wheel 42 ( figure 3 ) a chronograph mechanism of which it is endowed.
  • the watch may also include a thirty minute counter to display the minutes of the timed time, a small second 34, that is to say a display of the second of the current time in an off-center dial.
  • the hour and the minute of the current time can be displayed in a small dial 36, arranged at 6 o'clock, with reference to the main dial of the watch.
  • the watch comprises a first START / STOP button 38, typically arranged at 2 o'clock, to start and stop the measurement of a timed time, and a second button RESET 40, typically arranged at 4 o'clock, for the delivery zero display organs timed time.
  • the watch according to the invention comprises a first catch-up mechanism, arranged, like the chronograph mechanism on the bottom side of the watch.
  • the watch includes a chronograph wheel 42, driven by the movement of the watch when the chronograph is engaged, typically, so as to display the second of a timed time.
  • the chronograph wheel 42 is pivoted on a pin 44, cooperating with a stone 46 housed in a bridge 48 located on the bottom side of the watch. As will be seen later, the end of the pin passes through the stone 46 and opens out beyond the bridge 48.
  • a tube 50 is mounted integral with the chronograph wheel 42 and passes inside the pin 44 and through of the stone 46. The tube 50 passes through the movement of the watch and its end protrudes beyond the dial, to receive the second hand 30.
  • the tube 50 is furthermore pivoted on an element 52 of the frame of the watch, that is to say on a bridge or on a platinum. Preferably, because of its length, the tube is pivoted on a bearing 54 of sufficient height, to ensure good guidance.
  • a first core 56 is mounted integral with the pin 44, to ensure the return to zero of the second needle 30, in cooperation with a not shown hammer.
  • the first catch-up mechanism is of the type described above with respect to the state of the art.
  • the relevant reference numbers in particular have three figures and begin with 1.
  • It comprises a second core 158 mounted integral with the end of the tenon 44, under the bridge 48.
  • It also comprises a split wheel 160, coaxially mounted to the chronograph wheel 42.
  • a lever 162 is carried by the split wheel 160, to cooperate with the heart 158, under the effect of a spring 164.
  • a first locking mechanism 166 ( figure 4 ) of the split wheel 160 is arranged to stop the rotation of the latter.
  • the catch-up mechanism itself is of conventional type and therefore does not need to be further described. All of the elements that have just been described with reference to the first catch-up mechanism are therefore mounted on the bottom side of the movement.
  • the split wheel 160 is mounted on a pivot 174, cooperating with a stone 176, housed in an element of the frame.
  • the axis is extended by a rod 178 positioned and dimensioned so as to take place freely within the tube 50.
  • the rod 178 extends beyond the tube 50 and receives, at its free end, a needle 180 for the display of the second of a first intermediate time.
  • This needle 180 is located above the second hand 30, that is to say, it is closer to an ice that would close the watch on the side of a display area.
  • the invention proposes, in addition to the first catch-up mechanism described above, to associate with the chronograph mechanism, a second catch-up mechanism.
  • the reference numbers relating thereto in particular have three digits and begin with 2. It comprises a third core 258 mounted integral with the tube 50, that is to say on the axis of the chronograph wheel 42. It comprises also a second catch-up wheel 260 mounted at the base of a second tube 261 and freely pivoting on the first tube 50.
  • a lever 262 is carried by the split wheel 260, to cooperate with the heart 258, under the effect of 264.
  • a second locking mechanism 266 ( figure 5 ) of the split-second wheel 260 is arranged in order to stop the rotation of the latter.
  • It may comprise a clamp or a rocker 268 carrying a spout, whose position is determined by a second control member, such as a column wheel 270, actuated by a fourth button 272, typically arranged at 8 hours.
  • a second control member such as a column wheel 270
  • a fourth button 272 typically arranged at 8 hours.
  • the chronograph mechanism is controlled by a column wheel 70 and the splitters mechanisms are also each controlled by a column wheel 170 and 270, there are two column wheels 70 and 170 on one side of the movement. , for example on the bottom side, and another 270 on the other side, for example on the dial side.
  • the second tube 261 passes through the dial and ends substantially around the end of the first tube 50.
  • the second tube 261 has a flange 273 acting as positioning and pivoting means with reference to the dial or to a member of the frame 282. It also comprises bearings 274 disposed between the first tube and it, in order to complete the guiding of the first tube 50.
  • On the second tube 261 is mounted a second needle 280 for displaying the second of a second intermediate time. This needle is located below the chronograph hand 30, that is to say, it is further away from an ice that would close the watch on the side of a display area.
  • the first catch-up needle 180 whose barrel is mounted on the rod 178, which passes through the first tube 50.
  • the barrel On the latter is mounted the second hand of the chronograph 30, the barrel is, at least partially housed in the second tube 261.
  • the second split-second needle 280 On the latter is mounted the second split-second needle 280.
  • the outer and inner diameters of the barrels of the needles are therefore more and more important, the first split-second needle 180 to the chronograph hand 30, and from it to the second second hand of the second catcher 280.
  • each of the two smaller guns takes place, at least partially, inside the barrel of the needle below him.
  • the tubes and rod, intended to receive a needle or other index form display members of the movement. It should also be noted that displaying the current time in small off-center dials makes it possible to have more space available in the center of the watch for the chronograph switch and the splitters.
  • the invention therefore consists in associating two split-second mechanisms with a single chronograph mechanism and not simply combining two devices of the state of the art each comprising a chronograph mechanism and a split-second mechanism.
  • each of the catwalk needles can catch up with the chronograph hand 30 by a new pressure on its control button, completely independently of the other catch-up mechanism. Any sequence is possible. One can even take two consecutive measurements of split time with the first split-second needle, while the other continues to follow the chronograph hand or remains immobilized on the display of another intermediate time. Naturally, to distinguish the different needles, it can provide varied colors.
  • the visual appearance obtained, when one of the splitters needles is stopped, is particularly aesthetic, since it has the impression of a simple split-second, the user having the illusion that only the chronograph hand continues its course.
  • This effect is advantageously obtained thanks to the small distance between the chronograph hand and each of the split-second needles.
  • the watch obtained according to the invention comprises four buttons 38, 40, 172, 272, arranged in pairs, symmetrically with respect to the axes 9 hours-3 hours and 12 hours-6 hours.
  • the description above has been given by way of non-limiting example of the invention.
  • the person skilled in the art could thus consider displaying other units of time than the seconds of the intermediate times, the minutes by example.
  • the chronograph could be of the monopusher type, which would allow other provisions of the split-seconds push-buttons.
  • one skilled in the art can provide to arrange insulators in each of the splitters mechanisms, in order to limit the friction of the lever on the split-second core.
