Definitions

  • the present invention relates to chronograph mechanisms, which allow the measurement of a time counted from a given instant, controlled by pressing push buttons.
  • a watch fitted with such a mechanism is, for example, described in the work titled "Clockmaking theory" Chs-A. Reymondin et al. ISBN 2-940025-10-X, page 232 and following.
  • These watches generally have two pushers intended for one to ensure the start and stop of the counter ensuring the measurement of the timed time, the other resetting this counter. This time is displayed by means of at least one needle, generally placed in the center of the movement and indicating the time in seconds.
  • the actuation means further comprise an initialization device, arranged to control the resetting of timed time counting means.
  • its switching device includes a locking structure arranged in such a way that it cannot be actuated only when one of the chronograph cogs is engaged.
  • the locking means cooperate with the means actuation, so that the initialization means cannot be activated when one of the chronograph cogs is engaged.
  • the position of the various components of the watch is sometimes defined with reference to the position of an hour hand on the dial.
  • the box 12 contains and protects a movement comprising a mechanism allowing the timing of time, as will be explained further. It is closed by a glass, not visible in the drawing, and which covers the dial 14 and hands 18 to 23.
  • Hands 18 and 19 rotate in the center of dial 14. They display hours and minutes respectively of current time. Needles 20 and 21 are arranged concentrically with needles 18 and 19. They are respectively driven by a first and a second counter and intended to display the seconds of a first and a second beat stopwatch. Hands 22 and 23, which are off-center and associated with a small dial not referenced and placed at three o'clock, ensure the display of the minutes first and second timed times respectively. Needles 20 to 23 therefore take the place of timed time display means.
  • Pusher 24 placed at two o'clock, controls either the start or the stop of the measurement of one or the other of the two timed times, according to a logic which will be described with reference to FIG. 2.
  • the pusher 25, coaxial with the crown 16, ensures the switching from one to the other of the counters and the pusher 26 la reset needles 20 to 23.
  • FIG. 2 schematically represents the effect that generates pressing one or the other of the pushers.
  • the inactive pushers in the different states that the mechanism were not taken into account.
  • the pusher 24 can be actuated whatever the state in which the mechanism.
  • the push-button 25 is only active if one or the other of the counters is in function, while the pusher 26 can only reset to zero when the first counter is stopped and the second counter is stopped or zero.
  • rectangles in bold lines relate to actions P1, P2 and P3, performed by the user of the watch respectively on the pushers 24, 25 and 26.
  • the watch is in state A when no time is timed, the hands 20, 21 22 and 23 being at zero.
  • a pressure P1 on the pusher 24 is active. It causes the start of the first counter and the setting in motion of the hands 20 and 22, the hands 21 and 23 remaining at zero, which corresponds to the state B of the mechanism.
  • pressing the pusher 24 (P1) again has the effect of stopping the first counter, consequently the hands 20 and 22 indicating the time measured, which corresponds to the state C of the mechanism.
  • Pressure on push-button 25 (P2) is also possible. It causes the counters to switch, ie stop the first and start the second, the mechanism then being in state D.
  • the pushers 24 (P1) and 25 (P2) can be activated, which is comparable to state B.
  • the second counter stopped, indicates a measured time, while in state B , it was zero.
  • FIGS. 3 to 6 The mechanism ensuring these functions is shown in FIGS. 3 to 6. It is arranged on a plate forming a frame 28, part of the basic movement and able, for example, to further perform a barrel bridge function. It is on the back side of the watch.
  • the constituent parts are in state A as defined with reference to FIG. 2, that is to say in the state where the mechanism is at rest, the hands 20 to 22 being at zero .
  • Figure 4 corresponds to state B , Figure 5 to state D , and Figure 6 to state C or D.
  • the pushers 24 to 26 are shown schematically by their end arranged inside the box.
  • the basic movement has not been shown. It includes, so classic, a source of energy, a time base, and a cog in finishing ensuring the link of the energy source to the time base and consequently the counting of current time.
  • This cog comprises a mobile provided with a shaft crossing the frame 28 and carrying two wheels 301 and 302, the function of which will be specified below.
  • the timed time counting means 40 comprise two wheels 421 and 422, of the same diameter and provided with the same number of teeth, arranged coaxially in the center of the movement, and arranged to carry respectively needles 20 and 21. They also include two coaxial wheels, which have no not shown in the drawing, arranged to pivot on the frame 28 in a hole 28a, and driven respectively by the wheels 421 and 422, at a rate of one step per minute or half minute, and arranged so that the hands 22 and 23, which they wear respectively, make a turn in thirty minutes. These wheels timed time counting means 40 are each provided with a heart, not shown in the drawing, intended to cooperate with the means to reset the hands to zero.
  • the connecting means 50 comprise two rockers 521 and 522, mounted pivoting on the frame 28, in their middle part on the same axis, which is found outside the drawing frame. These flip-flops 521 and 522 bear, to one from their ends, a wheel mounted mad and identified by the letter a. They are fitted, at the other end, with a nose identified by the letter b and intended to cooperate with the actuating means 60, as will be explained more far.
  • the wheels 521a and 522a are arranged so that they mesh permanently with wheels 301 and 302 respectively and sequentially with the wheels 421 and 422, with reference to the actuation means, as this will be explained later.
  • the wheel 421 and the first of the wheels not shown and pivoting at 28a together form the first cog in timed time, while wheel 422 and the second of the wheels not shown form the second cog in timed time.
  • the scale 521, with its wheel 521a, forms the first clutch and the rocker 522, with its wheel 522a, the second.
  • the initialization means 70 are all visible only in FIG. 6. They include a control lever 71 and a hammer 72, respectively pivotally mounted in 281 and 28m on the frame 28.
  • the lever 71 carries a pin 71a, arranged so that the pusher 26 can activate it. It is provided with a nose 71b, called to cooperate with the pawl 69d, and an arm 71c, forming a stop for the hammer 72.
  • the hammer 72 is formed by a body 72a, which carries, in the vicinity of its point of 28m swivel, a pin 72b and two overlapping noses 721c and 722c.
  • the pin 72b is intended to cooperate with the arm 71c, while the noses 721c and 722c are arranged to work respectively with the columns of the wheels 661 and 662.
  • the other end of the body 72a carries two arms 72d and 72e each provided with its free end of two superimposed heels, namely heels 721 d and 722d for the arm 72d, 721e and 722e for the arm 72e. These heels are intended to cooperate with the hearts with which the wheels carrying the needles 20 to 23 are provided.
  • the rest position of the different parts constituent is, generally, defined by the action of a spring now each piece in abutment.
  • these springs are simply represented by an arrow, in order to avoid overloading the drawing.
  • the bodies 62 la and 622a of the levers 621 and 622 are respectively maintained in place, against a stop not shown, by springs F621a and F622a superimposed and marked F621 / 2a in FIG. 3.
  • the pawls 621b and 622b are respectively constrained by springs tending to keep them in contact with the ratchet of column wheels 661 and 662, noted F621 / 2b.
  • the switching lever 64 is supported by its contact finger 64f against the cam 67b, under the effect of a spring F64a acting on its body 64a.
  • the arm 64b is pressed against a stop integral with the frame 28 and schematically shown by a pin 28n, under the effect of a spring F64b.
  • the 64d ratchet is positioned against the pin 64e by a spring F64d.
  • the selection lever 65 is subjected to a spring F65a, acting on the body 65a so that the nose 65b is in abutment against the cam 68b, and a spring F65c applying the arm 65c by the pin 65d against the lever 621 or 622.
  • Lever 71 is subjected to a spring F71 which tends to resist the applied force by pusher 26.
  • a spring F72a is pressed against the body 72a, so that the heels come to bear against the hearts when neither the noses nor the pin 72a are more retained respectively by the arm 71c and the columns of the wheels 661 and 662 (figure 6).
  • actuation means ensure both a control and switching function. They thus constitute a control device, consisting essentially of rocker 61 and levers 621 and 622, and a switching device formed essentially by the lever switching 64 and selection lever 65.
  • the pawl 621b drives the column wheel 661, so that the nose 521b is between two columns and that the rocker 521 moves until ensuring the meshing of the wheel 521a with the wheel 421.
  • the first counter timed time is engaged.
  • the pawl 61c cooperating with the star wheel 67a drives the coordination wheel 67.
  • the tilting of the lever 64 brings the pin 64c into the space swept by the pusher 25, thus ensuring a clutch structure function, allowing actuation of the switching device, as will be explained more far.
  • These lever movements have no immediate effect, they only place these pieces so that they can be activated later, as will be explained later.
  • the hammer 72 also pivots during actuation of the pusher 24. Indeed, because of the rotation of the wheel column 661, the nose 721c is raised by a column. Heels 721d, 722d, 721e and 722e then release the wheels from the chronograph cogs, in particular the wheels 421 and 422.
  • actuation of the pusher 24 causes, in a similar manner to what has been described with reference to FIG. 3, the displacement of the rocker 61, which causes the column wheel 661 to rotate a new step and the coordination wheel 67.
  • the rotation of the column wheel 661 brings the nose 521b into abutment against a column, so that the wheel 521a is again disengaged from the wheel 421.
  • the mechanism is then in state C , that is to say that the first counter is stopped and displays the first timed time, while the second counter is at zero. In this state, the mechanism occupies the same position as that shown in Figure 3. There are however two differences between states A and C. On the one hand, the timed first time counter is no longer at zero, and on the other hand, the hammer 72 is in the wheel release position and not in the initialization position. These differences do not appear in Figure 3.
  • the pin 64c pushes simultaneously the levers 621 and 622, by leaning against their fingers 621d and 622d, so that the pawls 621c and 622c drive column wheels 661 and 662 by one step respectively.
  • 521 which was between two columns, passes against a column, while rocker 522, which was in abutment against a column, fell between two columns.
  • the wheel 521a is disengaged from the wheel 421, this which interrupts the counting of the first timed beat, and the wheel 522a is clutched with wheel 422, which triggers the counting of the second time stopwatch.
  • the pawl 64d pushes the wheel one step 68.
  • the selection lever 65 is supported there, by its nose 65b, it rocks and takes a position such that the pin 65d is in look of cutout 621c.
  • state D it is also possible to actuate the pushers 24 and 25.
  • a pressure on the pushbutton 24 causes, in a similar manner to what has been explained above, the pivoting of the rocker 61, which drives the arm 65c which is in a position such that its pin 65d controls the lever 622 only.
  • the latter rotates the column wheel 662 by one step, so that the lever 522 abuts against a column and the wheel 522a and is disengaged from the wheel 422.
  • the second counter like the first, is therefore stopped , which therefore corresponds to state E , in which the parts shown in the drawing occupy the same position as in state C.
  • the only difference lies in the position of the hand 21 which displays a time, while in state C , it is zero.
  • the nose 71b pushes the pawl 69d, which drives the wheel. coordination 68 by its star 68a, so that the selection lever 65 occupies the position where a pressure on the pusher 24 causes the engagement of the timed first time counter.
