- the display is made, generally by means of hands mounted on a movement mobile, one hand per function displayed.
- the number of hands is large and tends to overload the dial.
- the object of the present invention is to simplify the display by ensuring the indication of at least two pieces of information with the same organ.
- the display device comprises:
- a display mobile pivotally mounted on the frame around said axis and arranged to carry said member, • first and second information wheels, the angular position of each of which depends on the state of the information to which it is associated,
- first and second connecting members intended to connect the first and second information wheels respectively to the display mobile and to position it so that said display member occupies a position corresponding to the state of said function
- a manual control member cooperating with the connecting members so that either one or the other provides the link between the information wheel with which it is associated and the display mobile.
- the control member the user can control the display of one or the other of the information, one or the other of the connection members kinematically connecting one of the information wheels to the display mobile, so that the display mobile has a position corresponding to the angular position of the information wheel concerned.
- the first information wheel is coaxial with the display mobile and that the first connecting member comprises a cam and a hammer provided with an elastic member arranged to keep the hammer in abutment against the cam, one being mounted on the display mobile, the other on the first information wheel. In this way, as long as the control member is not activated, the display mobile is rotated in synchronism with the first information wheel.
- FIG. 1 represents a watch of the chronograph type provided with a display device according to the invention ;
- FIG. 2 is a logic diagram of the operation of the movement according to the invention.
- Figure 3 is a sectional view of a movement provided with a display device according to a first embodiment of the invention, u Figures 4a to 4d show the dial side of the movement of Figure 3, in different states corresponding to the steps defined in the diagram of FIG. 2, and
- Figure 5 illustrates the back side of the movement of Figure 3, when the chronograph function is locked.
- Figures 6 and 7 show a part of watch movement provided with a display device according to a second embodiment of the invention, comprising only one hand displaying either the hour or the minute, seen in section on the Figure 6 and in plan in Figure 7.
- the watch shown in Figure 1 is of the chronograph type, it conventionally comprises a case 10 serving as a housing for a movement, which carries a dial 12, hour hands running time 14, minutes of running time and timed time 16 and seconds of timed time 20.
- the display of the current time is corrected by means of a time setting crown 22, connected to the movement organs by a time setting rod not visible in the drawing.
- the timing functions are performed by three pushers 24, 26 and 28 respectively arranged at two o'clock, four o'clock and eight o'clock.
- the pusher 24 controls the start and stop of a timed time measurement, while the pusher 26 ensures the setting of the hands 16 and 20 to zero when a timed time measurement has been interrupted.
- the pusher 28 allows the chronograph mechanism to pass from a first state, in which it is locked, to a second state in which it is unlocked.
- the hand 16 When the chronograph mechanism is locked, the hand 16 displays the minutes of current time, while, when it is unlocked, it indicates the timed time. In the locked state, the pushers 24 and 26 are inactive.
- This mechanism is part of a movement which comprises, in a conventional manner and not visible in the drawing, an energy source such as a barrel, a time base such as a balance spring, a gear train, of which only a mobile 29 is visible in FIG. 4a, and an exhaust connecting the gear train to the balance for maintenance, as well as mechanisms for setting the time and chronograph.
- the different components of the movement are arranged on a frame 30, formed of a plate and bridges, which ensures the relative positioning of the different moving parts.
- Figure 2 illustrates the effect of the different pushers according to the states of the chronograph mechanism, which are identified by a capital letter surrounded by a circle.

- the retaining lever 392 is mounted on the frame 30, pivoting in its middle part. It carries, at one of its ends, the wheel 393 which can turn on a tenon 392a driven into the lever 392, while the other end forms a nose 392b which, as will be explained below, makes it possible to control the movement of the lever 392.
- a spring F392 tends to apply the nose 392b to a bearing surface.
- the wheel 393 is formed of two boards 393a and 393b, connected together by a snap 393c and respectively capable of being engaged with the teeth 34c and 391d.
- the snap 393c is arranged so that, when the mobile 34 rotates clockwise, the snap is blocked, so that the board 393b drives the mobile 391 in rotation.
- the lever 394 comprises (FIG. 4a): a body 394a pivotally mounted on the frame 30, by engagement of a hole 394b made at one end of the body 394a of the lever in an unreferenced tenon, integral with the frame 30, - a nose 394c, located in the vicinity of the hole 394b, and intended to control the movement of the lever 394, a tenon 394d driven into the body at the end opposite to that provided with the hole 394b, on which the pawl 395 pivots, and a pin 394e, forming a stop and limiting the movement of the pawl 395.
- the lever 394 is positioned by pressing the nose 394c against a bearing surface, by the action of a spring F394.
- a spring F395 tends to keep the pawl 395 in abutment against the pin 394e.
- the insulating mobile 391 can be moved at an angle of approximately 45 ° relative to the mobile 34, by engagement of the pawl 395 in the teeth 391c. During this movement, the pin 391e, moving freely in the cutout 34d, lifts the hammer 36 whose free end is brought out.
- the movement shown in the drawing comprises a chronograph seconds wheel 40, pivotally mounted in the tube 32, visible in FIG. 5 and partially in FIG. 3, as well as a walkman 42 ( Figures 3, 4c and 5).
- the wheel 40 comprises a shaft 40a, pivotally mounted in the tube 32 and in the frame 30, a board 40b driven on the shaft 40a and provided with a toothing, a cam 40c, also driven on the shaft 40a, and a training finger 41.
- the chronograph mechanism further comprises and not visible in the drawing, a clutch provided with a wheel which, when the chronograph mechanism is in state C, kinematically connects the wheel 40 to the gear train, so that it is rotated, one revolution per minute. Such a clutch is well known to those skilled in the art.
- the player 42 includes a shaft 42a (FIG. 3) rotatably mounted in a stone 43, with an olive hole, driven on a bridge of the frame 30 and on a rocker 44, itself pivoting on the frame 30 and which will be described in more detail detailed below. It further comprises two wheels 42b and 42c, respectively intended to cooperate with the finger 41 and with the wheel 38. Depending on the position occupied by the lever 44, the wheel 42b is or is not in the space swept by the finger 41. Furthermore, the wheel 42c is permanently engaged with the toothing 38b. The rocker 44 tends to move in the direction of the center of the movement, under the effect of a spring F44 ( Figure 5).
- the chronograph mechanism When the chronograph mechanism is in one of the states B, C or D, the hammer 36 is lifted by the pin 391e, so that it is no longer in abutment against the cam 38d. The mobile 34 and the wheel 38 are therefore no longer integral in rotation.
- the shaft 42a when the mechanism is in state C, the shaft 42a is arranged parallel to the axis AA and its wheel 42b can be rotated by the finger 41, by one step at each revolution of the wheel 40.
- the player 42 performs a function of link between the timed seconds wheel 40 and the wheel 38, so that the latter allows the display of the minutes of timed time when the mechanism is found in state C or D.
- the retaining wheel 393 is brought into engagement with the teeth 34c of the mobile 34 and 391 d of the isolation mobile 391, the two boards 393a and 393b being made integral in rotation by the snap-fastening 393c.

- the switch 46 is controlled by the push-button 28. It makes it possible to bring the minute hand 16 to zero, and to activate the push-button 24. It has, for this purpose (FIG. 4a): - a switching member 461, including:
- a body 461a in the shape of a bird, with a head 461b provided with a hole 461c in which is engaged a rod passing through the frame 30 right through and carrying a finger
- a beak 461e visible in FIG. 5, a beak 461e, two wings 461f and 461g, the wing 461g being provided with a pin 461h, and a tail 46 lj, the head being arranged on the side of the center of the movement and the tail 46 lj on the outskirts, around 7 am,
- a lever 461k pivotally mounted on the tail 46 lj and extending around the periphery of the movement from 7 to 9 hours, provided with a pin 461m arranged so as to be find or not on the path traveled by the pusher 28 when it is actuated according to the position occupied by the lever 461k, and with a stop 46 In disposed at its free end,
- a switching cam for example a column wheel 462, diagrammatically shown, controlled in rotation by the pawl 46 lp, rotating on the frame 30 at 462a, and cooperating with the noses 392b of the rocker 392 and 394c of the lever 394, - an interlocking lever 464, comprising an elongated body 464a, pivotally mounted on the frame 30 in its middle part, and one end of which is provided with a nose 464b arranged to cooperate with the columns of the wheel 462, while the other end comprises a first oblong hole 464c in which a stud 465 is slidably mounted, intended to cooperate with the control device 48, and a second oblong hole 464d, in which is housed a pin with head 466, itself fixed on the frame 30, ensuring the positioning of the lever in the plane of movement.
- the control device 48 is more particularly visible in FIG. 5. It comprises: a control lever 481 comprising:
- a body 481a disposed at the periphery of the movement from 2 to 7 hours, which pivots at 481b on the frame 30 slightly below 4 hours, and which is provided, at one of its ends, with a folding 481c s 'extending in the thickness of the pad 465, and
- a pawl 481d pivotally mounted on the other end of the body 481a, the function of which will be specified below, a cam 482, for example of column wheel type, driven by the pawl 48 ld, which controls the clutch of chronograph, not shown in the drawing, and positions the switching member 461 by its finger 46 ld.
- the constituent parts of the control device 48 are positioned by springs and more particularly: the body 481a, by the spring F481a which tends to bring back when a pressure has been applied to the pusher 24, and the pawl 481d, by the spring F481d, which applies it against the cam 482.
- the reset device 50 comprises: a reset lever 501 (FIG. 4a), disposed and mounted pivoting at the periphery of the frame 30 and extending from 4 hours to 6 hours, provided at its end close to 4 hours a pin 501a intended to cooperate with the pusher 26, and at its other end with a groove 501b intended to cooperate with the pin 46 lh, a hammer 502 for resetting the minutes placed in the vicinity of the column wheel 462 and extending up towards the central part of the movement to cooperate with the cam 38d by a bearing surface 502a, provided with: “ A nose 502b, which cooperates with the columns of the wheel 462, and
- the constituent parts of the zeroing device 50 are positioned by springs and more particularly: the lever 501 , by the spring F501, which tends to bring it back after a pressure has been applied to the pusher 26, the hammer 502 by the spring F502, which tends to apply the bearing surface 502a against the cam 38d, and the hammer 503 by the spring F503, which tends to apply it against the cam 40c.
- the movement further comprises a moving body of the hours of current time 52, pivotally mounted on the barrel 38c of the wheel 38 of the minute hand.
- the mobile 52 carries the hour hand 14 of current time. It is kinematically connected to the mobile 34 by a timer train, which divides the movement by a factor of 12. This timer train has not been shown to avoid overloading the drawing.
- the chronograph mechanism When the chronograph mechanism is at rest, ie in state A defined with reference to FIG. 2, its constituent parts are in the position shown in FIGS. 4a, 4b and 5. More specifically, the nose 392b of the lever retaining 392 is located between two columns of the column wheel 462 under the effect of the spring F392, so that the retaining wheel 393 is not engaged with the teeth 34c and 391d. The nose 394c of the lever 394 is also between two columns under the effect of the spring F394, so that the pawl 395 is set back from the teeth 391c.
- the hammer 36 under the action of the spring F36, bears against the cam 38d.
- the wheel 38 of the minute hand therefore rotates in synchronism with the mobile of the minutes of current time 34.
- the engagement lever 464 is supported, by its nose 464b and under the effect of the spring F464a, against a column of the wheel 462, so that the stud 465 is not interposed between the pusher 24 and the folding 481c, which makes the pusher 24 inactive. Furthermore, an action on the pusher 26 pivots the lever 501, but without it acting on other parts.
- Pressing the pusher 28 actuates the pin 461m, which carries with it the lever 461k, which switches the chronograph mechanism. More precisely, the tilting of the lever 461k, causes the pawl 46 lp, which rotates the column wheel 462 and generates the following movements, which take place practically simultaneously or in the following order: the nose 392b of the retaining lever 392 is lifted by a column, which brings the wheel 393 into engagement with the teeth 34c and 391d; the nose 394c of the lever 394 is raised, so that the pawl 395 engages with the toothing 391c, driving in rotation, clockwise, the mobile 391 and the only board 393b, the board 393a, engaged with the mobile 34, being disengaged, because of the snap 393c; during the relative movement of the mobile 391 with reference to the mobile 34, the pin 391e lifts the hammer 36, so that the cam 38d of the wheel 38 is no longer kept in phase with the mobile 34; - The nose 502b of the
- the mechanism is then in state B defined in Figure 2 and shown in Figure 4c.
- the link member formed by the hammer 36 and the cam 38d then no longer ensures the link between the wheel 38 and the mobile 34.
- the switch 46 thus plays the role of control member, and deactivates this link member.
- the pushers 24 and 28 are functional. By pressing the pusher 28 again, the lever 461k, switches and drives the pawl 461p.
- the wing 461f lifts the hammer 502 by its pin 502c, thus authorizing the rotation of the wheel 38 of the minute hand.
- the pivoting of the body 461a 461h causes its pin in the groove 501b of the reset lever 501.
- the connecting member forms the player 42, controlled by the control device 48 via the hammer 503, goes from the deactivated state to the activated state.
- FIG. 4d corresponds to state C of FIG. 2.
- the pin 461m is offset relative to the pusher 28, which makes the latter inactive.
- the body 461a the position of which is defined by the finger 46 ld pressing against a column of the cam 482, remains in this position, even if the groove 501b releases the pin 461h. In other words, pressing the pusher 26 has no effect. Pressing the pusher 24 brings it into abutment against the stud 465 which slides in the oblong hole 464c and, applied against the folding 481c, makes the lever 481 pivot. Its pawl 48 ld (FIG.
- the hammer 503 is retained by means similar to those retaining the hammer 502, but which have not been shown to avoid overloading the drawing.
- the chronograph mechanism is then in state D of the logic diagram in FIG. 2. This state, which is not shown in the drawing, allows action on pushers 24 and 26. Pressing pushbutton 24 starts again. counting the time, the mechanism returning to state C by a new rotation of the cam 482. Thus, the chronograph clutch is reset, while the hammer nose 503a and the finger 461d are in abutment against a column of the cam 482.
- the chronograph mechanism is again in the defined state B above, so that it is possible to press on the pusher 28, to return the mechanism to state A, where the pusher 24 and 26 are inactive and where the minute hand 16 displays the minutes of time current. It is also possible to press push-button 24 to start a new measurement, the mechanism being in state C.
- the display device shown in Figures 6 and 7 provides the indication of either the minute or the hour. It is shown in the display position of the minute in FIG. 7a, of the hour in FIG. 7b. It is intended to equip a watch movement comprising a frame 110, which carries a source of energy, in this case a barrel 112, visible in FIG. 6, which drives a gear train, the first mobile of which is a wheel of the minutes 114.
- the latter positioned at the center of the movement, pivots on the frame 110 around an axis AA and carries a pavement 116 frictionally mounted and which meshes with a timer wheel 118, which drives a hour wheel 120.
- the carriageway 116 and the hour wheel 120 perform respectively one revolution in sixty minutes and in twelve hours, their angular position defining the state of the information to be displayed. They therefore provide an information wheel function.
- the pavement 116 and the timer wheels 118 and hours 120 play the role usually assigned to the clockwork in the classic watch movements, with the difference that none of these mobiles carries a needle.
- the roadway comprises a tubular portion 116a, pierced right through and engaged in friction on the large medium wheel 114, a pinion 116b secured to the portion 116a and meshing with the timer wheel 118, a wheel board 116c, fixed to the portion 116a, provided with a toothing 116d and carrying a hammer 122.
- the latter is pivotally mounted on a tenon 123 driven into the board 116c.
- This hammer is subjected to the action of a spring, schematically represented by an arrow FI in FIGS. 7a and 7b, which tends to push the hammer 122 in the direction of the axis A-A.
- the carriageway 116 carries, free in rotation, a display mobile 124 comprising, rigidly integral with each other, a board 124a provided with a toothing 124b at its periphery, a barrel 124c engaged on the tubular portion 116a and a cam 124d interposed between the board 124a and the board 116c, at the same height as the hammer 122.
- the hammer 122 is applied against the cam 124d.
- the display mobile 124 is rotated by the roadway 116, by means of the hammer 122 and the cam 124d, performing one revolution in sixty minutes. This situation is illustrated in Figure 7a.
- the barrel 124c carries a hand 126 which, under the conditions described above, therefore displays the minute of current time.
- the hour wheel 120 is offset from the center of the movement. It comprises a board 120a provided with a toothing 120b at its periphery which meshes with the pinion of the timer wheel 118. It is arranged to rotate freely on a tube 128 driven onto the frame 110. It carries a hammer 130 pivotally mounted on a post 130a driven into the board 120a. This hammer 130 comprises a head 130b and a shank 130c arranged on either side of the pivot point, the function of which will be specified below.
- the board 120a has an opening 120c in the form of an annular portion and extending over an angle of approximately 90 ° (FIGS. 7a and 7b).
- a control wheel 132 is mounted coaxially with the hour wheel 120 around the tube 128. It comprises a board 132a interposed between the wheel 120 and the frame 110 and provided, at its periphery, with teeth 132b. A pin 132c is driven into the board, arranged so that it is engaged in the opening 120c and protrudes from this opening, extending in the thickness of the hammer 130, and arranged so as to cooperate with the tail 130c.
- the boards 120a and 132a are each provided with a hole identified by the letter e.
- a wire spring 134 is interposed between these boards, its ends being engaged in the holes 120e and 132e ( Figures 7a and 7b).
- the display device further comprises a wheel 136 comprising, rigidly integral with each other, a board 136a provided with teeth 136b at its periphery, a shaft 136c rigidly fixed to the board 136a and pivotally engaged in the tube 128, as well as a cam 136d, interposed between the boards 136a and 132a, at the same level as the hammer 130.
- the wheel 136 has the same diameter and the same number of teeth as the indication wheel 124 with which it is connected kinematically by means of a reference 138 pivotally mounted on the frame 110.
- the hand 126 carried by the indication wheel 124, displays the information defined by the angular position of the minute wheel 114 when the device is in the position illustrated in the figure 7a.
- the pin 132c moves in the opening 120c. During this movement, it comes to bear against the tail 130c of the hammer 130 and raises it, so that the head 130c is pushed against the cam 136d and exerts a pressure which causes the rotation of the wheel 136 until it is in press on the most central part of the cam 136d. In this position, the wheel 136 occupies an angular position corresponding to that of the hour wheel 120.
- the tail 130c is arranged so that the pin 132c is held in its extreme position, which corresponds to a function notch.
- the wheel 136 As the reference 138 connects the wheel 136 to the indication wheel 124, the latter is also driven in rotation.
- the wheels 124 and 136 having the same number of teeth, they rotate in the same direction and at the same speed as the hour wheel 120. Pavement 116 is not involved in this movement.
- the hammer 122 is therefore lifted. In other words, the movement of the wheel 132 with reference to the hour wheel 120 changes the display from the indication of the minutes to that of the hours.
- the device according to the invention further comprises a control 140 slidingly mounted on the frame 110, a rake 142 disposed in the vicinity, the same new as the wheel 132, and controlled by a finger 140a that includes the control 140 and a spring 144 cooperating with the rake 142 to maintain it, in the rest position, in the position shown in FIG. 7a.
- a pusher not shown in the drawing, mounted sliding in the watch case, cooperates with the control 140 and pushes it in the direction of the axis A-A.
- the finger 140a tilted the rake 142, which drives with it the wheel 132, which controls the display of the time, by the process which has just been described.
- the spring 144 returns the rake 142 to its starting position which, by this movement, rotates the wheel 132. In this way, the pin 132c no longer retains the tail 130c of the hammer 130
- the spring 134 participates in this movement and reposition the wheel 132 in a position relative to the wheel 120 corresponding to that shown in FIG. 7a, the hand 126 therefore displaying the minutes again.
