Definitions

  • the present invention relates to a chronograph watch provided with a device for controlling the three conventional functions of a chronograph, that is to say starting, stopping and resetting to zero.
  • this column wheel 1 is a rotary element comprising in its lower part of the triangular teeth 2 and in its upper part of the columns 3.
  • this column wheel rotates, it drives and moves on the one hand, the end of the hammer 6 which releases the core 7 from the center wheel 8, and on the other hand, the intermediate rocker 9 which acts on the intermediate wheel 10, bringing the latter into contact with the center wheel 8 to mesh with the latter.
  • the start of the chronograph is thus obtained.
  • the column wheel shown by way of example, has six columns and eighteen teeth. It is therefore necessary to exert three presses on the large rocker 5 so that a column takes the place of the previous one, which corresponds to the three functions of the chronograph.
  • patent CH-466 152 describes a chronograph comprising a first lever actuated at one of its ends by a start push-button and at the other end by a second stop push-button and a second actuated lever by a third reset button.
  • patent CH-579,794 describes a chronograph in which the column wheel is replaced by a three-level cam performing the three functions of the chronograph.
  • the subject of the invention is a chronograph watch comprising a chronograph mechanism comprising a first push button controlling the start and stop of the chronograph and acting on an on and off rocker and a second push button controlling the reset of the chronograph and acting on a reset scale.
  • this watch comprises an on and off cam and a reset cam, these two cams being constituted by concentric rings, superimposed, arranged at the periphery of the watch movement.
  • These two cams respectively have on their outer periphery triangular latching teeth or notches on which the two rockers act to drive these cams in rotation and these two cams also have on their internal periphery teeth or notches acting on control levers gears constituting the chronograph mechanism.
  • the chronograph conventionally comprises, in its center, a chronograph wheel 20 which is provided with a heart 21 and a drive finger 22 and, on its periphery, respectively at 3 o'clock and at 6 o'clock, a wheel 23 of a minute counter fitted with a heart 24 and a wheel 25 of an hour counter fitted a heart 26.
  • the hands of these different counters and the second hand of the chronograph have not been shown.
  • the heart 21 is arranged on the chronograph wheel 20, and the drive finger 22 which extends vertically is arranged above the heart 21.
  • the heart 24 is arranged on the wheel of the minute counter 23, while the heart 26 is, on the contrary, disposed below the hour counter 25.
  • the watch does not have an indication of the second in the center, the seconds display of the current time being done on an off-center graduation at 9 o'clock provided on the dial, via a small second wheel 27 (figure 12).
  • this small second wheel 27 is driven from the seconds axis 28 by an additional wheel 29 and an intermediate seconds wheel 30 freely rotating about an axis 30a.
  • the additional wheel 29 is fixed directly on the seconds axis 28 below the chronograph wheel 20.
  • the wheels 29, 30 and 27 rotate, for example, at a rate of one step per second in in the case of a quartz watch, for displaying the standard time.
  • the wheels and hearts of the watch according to the invention are conventionally used in the chronology of chronographs and a person skilled in the art will easily be able to produce and assemble them, without it being necessary to describe them further.
  • a clutch wheel 31 capable of sliding along the axis 30a in order to take two positions, a engaged position, (low position shown in FIG. 5), in which it comes into contact with the wheel 30 which drives it in friction rotation and in which it meshes with the chronograph wheel 20, and a disengaged position, (high position shown in FIG. 5A) in which it is no longer in contact with the intermediate seconds wheel 30, but in which it still meshes with the wheel 20. Consequently, the wheel 20 rotates at the same speed as wheel 30, when the clutch wheel 31 is in the engaged position.
  • This clutch wheel 31 is surmounted by a flange 32, slightly spaced from the wheel 31 and defining therewith an engagement groove 33 for the clutch control 34 which will be described later. Finally, this clutch wheel 31 is held in contact with the wheel 30 by an elastic washer 35 fixed on a plate 35a driven on the axis 30a, this washer exerting pressure on the flange 32 in the direction of the clutch of the wheels 31 and 32.
  • This clutch wheel 31 is actuated by the clutch control 34 produced in two parts 36 and 37 cooperating with each other (see FIG. 12).
  • the part 36 is an arm of substantially rectangular shape and has at one of its ends a fork 38 and its other end with two legs 39 and 40.
  • the part 36 is positioned by two studs 41 and 42 and held by a bridge not shown .
  • the arm 36 has in its middle part an inclined plane 43.
  • the fork 38 penetrates into the engagement groove 33 and makes it possible to raise the clutch wheel 31, thanks to the flange 32.
  • the wheel 31 undergoes the antagonistic action of the washer 35.
  • the arm 36 is substantially free around the studs 41, 42.
  • the part 37 is a lever articulated around a pivot 44 and comprising three branches extending from this pivot 44, a clutch branch 45 whose end acts directly on the inclined plane 43, an elastic branch 46 acting as a spring and bearing against the watch plate and a control branch 47 coming into contact with two control cams 48, 49 which will be described later.
  • the clutch branch 45 and the spring branch 46 form a U capable of opening and closing by spreading or bringing the two branches 45 and 46 closer together, that is to say by more or less arching the branch forming a spring 46.
  • a portable player 50 comprising an axis 51 mounted pivoting in bearings 51a, 51b with a certain axial clearance, a hub 52 driven on this axis 51 and having at its ends annular shoulders on which are supported on the one hand a sliding wheel 53a and on the other hand a finger d 53b. Furthermore, the hub 52 has an annular clearance 53c which delimits with the drive wheel 53a a groove whose role will be explained later (see Figures 6 and 7).
  • this wander wheel 53a can take two positions, on the one hand a disengaged position (high position, represented by dashed line), in which the wheel 53a does not mesh with the drive finger 22 of the chronograph core 20, and in which the drive finger 53b does not mesh with the wheel 25 of the hour counter and on the other hand, an engaged position (low position, shown in solid lines) in which the wheel 53a meshes with the drive finger 22 and in which the drive finger 53b meshes with the wheel 25 of the hour counter. Note that in the two positions respectively engaged and disengaged from the player, the wheel 53a permanently meshes with the wheel 23 of the minute counter (see Figure 6).
  • the player 50 is actuated by a control lever 54 itself moved by the hammer 55 of the hour meter.
  • This control lever 54 is an elastic blade held by one of its ends to the plate by means of two studs 56, 57. Its other end 58 is engaged in the groove 53c to allow the assembly to be lowered to the against the natural elasticity of the blade.
  • the blade 54 has on its edge directed towards 6 o'clock an inclined plane 60 directed downwards and towards the six o'clock to cooperate with the hammer 55.
  • the hammer 55 comprises a lever articulated at one of its ends 61 around a pivot 62 (see FIG. 12). This end 61 also has a spout 63 acting in combination with the control cams 48, 49 which will be described later.
  • the other end of the lever has a hammer head 64.
  • This head 64 comprises an incline 65 which can cooperate with the heart 26 of the hour meter 25 and a control tab 66 which can cooperate with the inclined plane 60 of the control lever 54 .
  • a spring plate 67 is disposed under the control lever 54 to press the hammer 55 of the hour counter against the core 26.
  • This plate includes a portion 68 also held by the pads 56 and 57 and is extended laterally by a leaf spring 69 proper. The free end of this leaf spring 69 presses on a boss 70 of the hammer 55 of the hour meter 25.
  • the spout 63 makes it possible to pivot the hammer 55 to a first position shown in FIGS. 2 and 3 in which the control tab 66 of the hammer head 64 passes over the inclined plane 60 and presses on the upper surface of the control lever 54, which has the effect of lowering the end 58 of the control lever 54 and therefore also of engaging the player 50 with the counters 23 and 25 and the drive finger 22 of the chronograph wheel 20.
  • a second position shown in FIG. 4 the hammer head 64 presses on the heart 26 of the hour meter 25.
  • the lever 54 is bent upwards by its own elasticity and lifts the sliding device 50.
  • the spring 69 of the plate 67 moreover holds the hammer 55 in this second position.
  • This hammer 55 allows the hour counter 25 to be reset to zero.
  • This chronograph hammer 71 comprises two parts assembled together.
  • the first part 72 has two branches arranged in a V, a branch 73 forming a spring whose end bears against a stop 74 placed at the periphery of the movement and a control branch 75 whose free end is articulated around a pivot 76 and has a spout 77.
  • the second part 78 also has two branches, a short branch 79 ending in an incline 80 which can cooperate with the heart 21 of the chronograph wheel 20 and a long branch 81 ending in an incline 82 which can cooperate with the heart 24 of the minute counter.
  • the second part 78 is assembled above the first 72 by a rivet 83 on which it is mounted in rotation.
  • the part 72 has an oblong orifice 84
  • the part 78 comprises a spout 85 directed vertically downwards, this spout being introduced into the oblong orifice 84, when the two parts 72 and 78 are assembled.
  • the spout 85 has a width less than that of the oblong orifice 84 so as to provide a slight lateral clearance j between the parts 72 and 78 which allows them a small angular movement relative to each other.
  • This chronograph hammer 71 can take two positions. In the first position illustrated in FIG. 4, the inclines 80 and 82 press respectively on the hearts 24 and 21 under the action of the spring 73. In FIG. 4 which corresponds to the position of rest, this support is made on the flat of the hearts while it is done on the curved profile when the chronograph is reset. In the second position shown in FIGS. 2 and 3, the chronograph hammer 71 is moved away from the hearts 21 and 24 by further stretching the spring branch 73.
  • this chronograph wheel 20 can be blocked by means of a blocker 86 (FIG. 13).
  • This blocker 86 has a V shape, one of the branches of which has a curved end 87 which hooks directly onto the control lever 88 of the blocker 86 and the other branch of which is substantially rectilinear and has on its lateral face a braking surface 89 which can come into contact with the chronograph wheel 20 and block it.
  • the control lever 88 is articulated substantially in its middle, around an axis 90 and has a bent control arm 91 acting on the end 87 of the blocker 86 and a second arm having at its free end a front spout 92 and a rear spout 93.
  • minute counter 23 and the hour counter 25 are positioned respectively by jumpers 94 and 95. Their structures being conventional, they will not be detailed in more detail (see FIG. 11).
  • the device for controlling the three functions of the chronograph according to the invention notably comprises the on and off cam 48 and the reset cam 49.
  • these cams have been shown separately in FIGS. 9 and 10. They are constituted by two concentric rings guided on their peripheries and superimposed, the cam 49 being arranged below the cam 48 (see FIGS. 2, 3 and 4). These cams are guided by a milling (not shown) formed in the movement plate as is the date disc in a classic watch movement.
  • the chronograph cam 48 is movable in a unidirectional direction anticlockwise (arrow F '). It has over its entire inner periphery a series of identical trapezoidal teeth 96 and over its entire outer periphery a series of triangular snap-in teeth 97 identical. For a better understanding of the operation of the chronograph, some of these teeth 96 and 97 have been identified by literal indices in FIGS. 2, 3 and 4.
  • the reset cam 49 can move bidirectionally with a single step either clockwise (arrow F1) or counterclockwise (arrow F2). It has a notch 98a on its outer periphery substantially at 5.30 am and between 0 and 1 hour (substantially at 0.30 am) a notch 98b. On its internal periphery is provided a clearance 99a extending from the level of the external notch 98b and an internal notch 99f provided at 2 o'clock. Other internal notches 99b, 99c, 99d and 99e are respectively made at 9 o'clock, between 7 and 8 o'clock, at 7 o'clock and at 4 o'clock. As illustrated in FIGS.
  • the cams 48 and 49 are actuated by an on and off rocker 100 and by a reset rocker 101, both are of practically identical shape.
  • the on and off rocker 100 is articulated at one of its ends around a pivot 102, while the reset rocker 101 is articulated at one of its ends around a pivot 103.
  • the rocker on and off 100 includes a bean-shaped opening 104 which defines three particular positions of the rocker, namely a rest position in which the pivot 103 is in contact with the rounded 105 inside the opening, an unstable position in which the same pivot 103 is in contact with the other external rounded 106 of the opening and an intermediate position for crossing a hard point defined by the lateral edge of the opening 104 which for this purpose defines a notch 104a.
  • this rocker 100 comprises on its outer surface, substantially at the level of the opening 104, a pallet 107 folded at a right angle on which a 2H push-button can act, disposed substantially at 2 o'clock. Furthermore, at its free end, it is provided towards the outside with a spout 108 and towards the inside with a guide head 108a which slides on a support not shown and which guides the spout 108 parallel to the cams 48, 49.
  • the rocker 100 being disposed below the two cams 48 and 49, this beak 108 which is directed upwards is long enough to allow these two cams to be displaced by half a step in the opposite direction of the clockwise, each time the 2H push button is pressed.
  • the reset lever 101 comprises an opening 109 with a notch 109a, and two rounded corners 110 and 111, a pallet 112, a spout 113 and a guide head 113a.
  • This lever is actuated by a 4H push button and positioned substantially at 4 o'clock.
  • the spout 113 acts only on the reset cam 49.
  • the reset lever 101 is arranged below the on and off lever 100, but upside down with respect to the latter so that the pivot 103 around which said lever 101 pivots passes through the opening 104 of flip-flop 100 and vice versa.
  • the pivot 102, around which the rocker 100 pivots crosses the opening 109 of the rocker 101.
  • notches 99f and 99e allow the reset cam 49 to move back and forth without being hindered by the respective pivots 103 and 102 while limiting its movement to only one step.
  • a spring wire 114 is supported by its two arms against the rockers 100 and 101 to return them to their rest position, like the push buttons 2H and 4H, the spring wire resting on the inner wall d 'a watch plate P (visible only in Figure 14) in which the present movement is mounted.
  • a jumper 115 fixed in the movement plate comprises an actuating tab 115a at its free end to cooperate with the back of the outer teeth 97 of the cam 48.
  • the cam 48 takes a step of a tooth 96 in the direction of the arrow F '.
  • the reference numerals 96 indicate the teeth which are active during the movement, from the rest situation shown in FIG. 4, being understood that the literal indices correspond respectively to an action of the corresponding tooth on the beak 47 (tooth 96a), the beak 63 (tooth 96b), the beak 77 (tooth 96c), the beak 92 (96d) and the beak 93 ( tooth 96e) of the various organs controlled by the cam.
  • each half-step of the cam 48 corresponds to the passage of a triangular tooth 97 from the outer periphery of this cam 48.
  • the notch 104a then imposes the crossing of a hard point which is perceived by the user.
  • the spout 108 of this lever pushes the chronograph 48 and reset 49 cams by half a step in the direction F ', F2 by acting on one of the triangular teeth 97 and on the notch 98b.
  • the clutch wheel 31 which was initially raised comes in contact with the intermediate second wheel 30. This clutch wheel 31 then drives the chronograph wheel 20 and the chronograph hand, not shown.
  • the tooth 96b of the cam 48 and the side of the notch 99c of the cam 49 simultaneously raise the beak 63 of the hammer 55 which has the effect of rotating this hammer and releasing the hour counter 25.
  • the hammer 55 presses on the inclined plane 60 of the control lever 54, which has the effect of lowering the player 50 and bringing the wheel 53a of the player 50 to the height of the drive finger 22 of the wheel chronograph 20.
  • the drive finger 53b is placed at the height of the wheel 25 of the hour counter.
  • the two counters are driven simultaneously, the driving force being brought through the axis 28 and the additional wheel 29 belonging to the clock mechanism of the normal movement time.
  • the chronograph wheel 20 has made one revolution, its drive finger 22 advances the player 50 by one step, which also has the effect of advancing the minute counter 23 by one step. After 30 minutes, the player 50 has made a complete revolution and advances the hour counter 25 by one step.
  • the teeth 96d and 96e of the cam 48 also move naturally by half a step, but they cannot act on the lever 88 of the blocker 86, because the front spout 92 of the latter is held towards the interior by the upper range formed by the internal periphery of the cam 49, until the tooth 96e of the cam 48 supports the spout 93 of the lever 88. As a result, the blocker 86 remains separated from the wheel chronograph 20.
  • the chronograph is in the operating position shown in FIG. 2.
  • the rocker on and off 100 had returned to its initial position ( Figure 4) after the first press of the 2H button, thanks to the spring wire 114 shown only in Figure 14.
  • This wire 114 must be hard enough to overcome the resistance against the return scale 100 by notch 104a and so that the spout 108 passes over the top of the tooth 97 which precedes the one it has just pushed back, so as to be ready to act again on the cam 48.
  • the cam 48 is retained by the jumper 115 during the return of the on and off rocker.
  • the on / off rocker 100 moves as before so that the spout 108 causes the cam 48 to advance by half a step in the direction F 'only.
  • the cam 49 does not rotate since it has only one notch 98b and it has already been moved when the chronograph was started.
  • the front spout 92 of the control lever 88 of the blocker 86 falls between the teeth 96d and 96e of the cam 48 and in the clearance 99a of the cam 49.
  • the rear spout 93 of the control lever 88 of the blocker 86 falls in the hollow the tooth 96e and the next tooth of the cam 48.
  • the control branch 47 of the lever 37 falls into the hollow between the tooth 96a and the next of the cam 48 and also in the notch 99d of the cam 49, the arm 36 is actuated and lifts the clutch wheel 31 by separating from the intermediate seconds wheel 30.
  • the chronograph wheel 20 is therefore no longer driven. It will be noted that the notch 99d is only intended as a clearance so as not to hinder the movement of the branch 47 if necessary.
  • the reset is done by pressing the push button 4H which acts on the reset lever 101.
  • the latter performs a rotation movement identical to that already described with regard to the lever 100, however acting only on the cam 49 by means of its spout 113.
  • the latter presses on the side of the notch 98a of said cam. It rotates half a step clockwise (F1) and performs the following functions in the order mentioned below.
  • the spout 63 of the hour meter hammer 55 falls into the notch 99c of the cam 49 and releases the clutch lever 54 which lifts the player 50. It is therefore released from the drive finger 22 of the chronograph wheel 20 and the hour meter wheel 25.
  • the hammer head 64 falls on the heart 26 which returns to its initial position 0.
  • the spout 77 of the chronograph hammer 71 falls into the notch 99b of the cam 49 and these inclines 80 and 82 rotate the heart 21 and the heart 24 until the minute counter returns to its initial position, as well as the hand of the chronograph wheel.
  • the return to zero of the mobiles is caused by the force of the hammer springs (spring 69 for the hour counter 25 and spring 73 for the minute counter 23 and the chronograph wheel 20).
  • notch 99d of the cam 49 is wide enough that the latter cannot act on the spout 47 during the reset.
