Definitions

  • the present invention relates to a display device for a watch of the type comprising a movement provided with a frame and a display member, movable in rotation about an axis.
  • the object of the present invention is to simplify the display by providing the indication of at least two pieces of information with the same organ.
  • the display device comprises the features defined in claim 1.
  • the first information wheel is coaxial with the display and the first connecting member comprises a cam and a hammer provided with an elastic member arranged to maintain the hammer against the cam, one being mounted on the mobile display, the other on the first information wheel.
  • the display unit is rotated in synchronism with the first information wheel.
  • the watch represented on the figure 1 is chronograph type. It comprises, in a conventional manner, a box 10 serving as a housing for a movement, which carries a dial 12, hands of the hours of current time 14, minutes of current time and of timed time 16 and seconds of timed time 20.
  • the display of the current time is corrected by means of a time setting ring 22, connected to the movement members by a time setting rod not visible in the drawing.
  • the functions relating to the timing are provided by three pushers 24, 26 and 28 respectively arranged at two hours, four hours and eight hours.
  • the pusher 24 controls the start and stop of a timed measurement of time, while the pusher 26 ensures the zeroing of the hands 16 and 20 when a measurement of timed time has been interrupted.
  • the pusher 28 makes it possible to move the chronograph mechanism from a first state, in which it is locked, to a second state in which it is unlocked.
  • the needle 16 When the chronograph mechanism is locked, the needle 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 to the drawing, a source of energy such as a barrel, a time base such as a balance spring, a work train, of which only a mobile 29 is visible on the figure 4a , and an escapement connecting the gear train to the balance to ensure maintenance, as well as time setting mechanisms and chronograph.
  • the various components of the movement are arranged on a frame 30, formed of a plate and bridges, which ensures the relative positioning of the various moving parts.
  • the figure 2 allows to illustrate the effect of the different pushers according to the chronograph mechanism states, which are identified by a capital letter surrounded by a circle.
  • a pressure on the pushers 24, 26 and 28 respectively corresponds to the indications P1, P2 and P3.
  • the chronograph mechanism In the initial state, identified by A and corresponding to the situation illustrated by the Figures 4a and 4b , the chronograph mechanism is locked.
  • the chronograph seconds hand 20 is at noon and the minute hand 16 displays the current time, the pushers 24 and 26 being inactive.
  • a pressure P3 causes the unlocking of the chronograph mechanism.
  • the minute hand 16 aligns with twelve hours, thus superimposing on the second hand of timed time 20.
  • This state shown in FIG. figure 4c , is identified by the letter B.
  • the minute hand 16 thus displays the minutes of timed time, equal to zero at the beginning of the measurement.
  • a pressure P1 has the effect of starting the counting of a timed time, the seconds hand of timed time 20 starting to turn and, more slowly, the minute hand 16.
  • This state represented on the figure 4d and identified by the letter C, brings the display into a situation as illustrated by the figure 1 .
  • a new pressure P1 then has the effect of restarting the count, the mechanism is thus found in the C state, while a pressure P2 returns the needles 16 and 20 at noon, which corresponds to the state B.
  • Figures 4a and 4b represent the mechanism in its rest position, corresponding to state A, and the Figures 4c and 4d in positions corresponding respectively to the states B and C of the figure 2 . From Figures 4a to 4d , which show the movement on the dial side, some parts are removed or partially removed from one or the other of these figures, to better see the underlying parts.
  • the movement described below with reference to Figures 3 to 5 comprises, in a conventional manner and not visible to the drawing, a source of energy such as a barrel, a time base such as a balance spring, a finishing gear of which only a mobile 29 is visible on the figures 3 and 4 , and an escapement connecting the gear train to the balance to ensure maintenance, as well as time setting mechanisms and chronograph.
  • a source of energy such as a barrel
  • a time base such as a balance spring
  • finishing gear of which only a mobile 29 is visible on the figures 3 and 4 and an escapement connecting the gear train to the balance to ensure maintenance, as well as time setting mechanisms and chronograph.
  • These various components are arranged on a frame 30, formed of a plate and bridges, which ensures the relative positioning of the various moving parts of the movement.
  • the figure 3 represents the central part of the movement, seen in section along line III-III of the figure 4a , with an axis AA corresponding to the axis about which the needles 14, 16 and 20 pivot.
  • the door frame 30, fixed rigidly on its face on the dial side, a tube 32 comprising a plate 32a integral with the frame 30 and two cylindrical portions 32b and 32c, of axis coincident with the axis AA and arranged one after the other, connected by a shoulder 32d, and intended to serve as a fixed shaft for the pivoting of mobiles and wheels, as this will be explained below.
  • a mobile running time minutes 34 is pivotally mounted on the tube 32. It is provided with a barrel 34a engaged on the cylindrical portion 32b of the tube 32 and a board 34b having a toothing 34c at its periphery.
  • the barrel 34a, the board 34b and the toothing 34c are made in one piece.
  • the mobile 34 meshes permanently, by its toothing 34c, with the mobile 29 of the work train, in a gear ratio chosen so that it performs one revolution per hour of current time.
  • a minute hand wheel 38 is arranged free to rotate on the cylindrical portion 32c of the tube 32.
  • This wheel 38 is visible, in plan, only on the figure 4c . It comprises a board 38a provided at its periphery with a toothing 38b, and a barrel 38c engaged on the tube 32 and extending upwardly enough so that its free end is disengaged and allows the fixing of the needle of the minutes 16. The latter provides both the display of the current time and the timed time, as will be explained later.
  • the barrel 38c extends below the board 38a.
  • a cam 38d generally called a heart, and more particularly visible in plan on the Figures 4a , 4b and 4d , is attached to it by driving or welding. Its lower face bears against the shoulder 32d. This cam 38d is arranged so that it can cooperate with the hammer 36, as will be explained later.
  • the movement comprises an isolation device whose component reference starts with 39 and which comprises an isolation mobile 391 mounted on the barrel 34a, a flip-flop 392, a retaining wheel 393 pivotally mounted on the flip-flop 392, a lever 394 and a ratchet 395 mounted on the lever 394 ( figure 4a ).
  • Mobile 391 comprises two superimposed plates 391a and 391b, rigidly connected to one another and provided at their periphery with teeth respectively referenced 391c and 391d, and a pin 391e fixed in plate 391a ( figure 3 ). This last, inferior, is equipped with teeth of wolves, clearly visible on the figure 4a , while the toothing 391d of the upper board 391b has the same number of teeth and has the same profile and the same diameter as the toothing 34c. The pin 391e is engaged in the cutout 34d and extends to the level of the hammer 36.
  • the latch 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 stud 392a driven into the latch 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, interconnected 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. If, on the contrary, it is the latter which is turned clockwise, only the board 393b is driven, the latching 393c ensuring its disengaging function.
  • the lever 394 is positioned by the support of the nose 394c against a bearing surface by the action of a spring F394.
  • a spring F395 tends to hold the pawl 395 against the pin 394e.
  • the isolation mobile 391 can be moved at an angle of about 45 ° relative to the mobile 34, by engaging the pawl 395 in the toothing 391c. During this movement, the pin 391e, moving freely in the cut 34d, raises the hammer 36 whose free end is brought outwardly.
  • the movement represented in the drawing comprises a chronograph second wheel 40, pivotally mounted in the tube 32, visible on the figure 5 and partly on the figure 3 , as well as a player 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 includes, and is not visible in the drawing, a clutch provided with a wheel which, when the chronograph mechanism is in the C state, kinematically links the wheel 40 to the finishing gear, so that it is rotated at the rate of one revolution per minute.
  • a clutch is well known to those skilled in the art.
  • the player 42 has a shaft 42a ( figure 3 ) rotatably mounted in a stone 43, with an olive hole, driven on a bridge of the frame 30 and a latch 44, itself pivoted on the frame 30 and which will be described in more detail below. It comprises, in addition, 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 latch 44, the wheel 42b is or is not in the space swept by the finger 41. In addition, the wheel 42c is permanently engaged with the toothing 38b. The rocker 44 tends to move towards 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 no longer bears against the cam 38d.
  • the mobile 34 and the wheel 38 are no longer integral in rotation.
  • the shaft 42a when the mechanism is in the C state, the shaft 42a is arranged parallel to the axis AA and its wheel 42b can be rotated by the finger 41, one step at each turn of the wheel 40.
  • the player 42 acts as a connecting member between the seconds wheel of timed time 40 and the wheel 38, so that the latter allows the display of minutes of time timed when the mechanism is found in state C or D.
  • the isolation mobile 391 rotates with him, otherwise the control of the hammer 36 could no longer be ensured.
  • the retaining wheel 393 is brought into engagement with the teeth 34c of the mobile 34 and 391d of the isolation mobile 391, the two boards 393a and 393b being made integral in rotation by the latching 393c.
  • the movement further comprises a moving time running time 52 pivotally mounted on the barrel 38c of the minute handwheel 38.
  • the mobile 52 carries the needle 14 hours 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 wheel has not been shown to avoid overloading the drawing.
  • the chronograph mechanism When the chronograph mechanism is at rest, in state A defined with reference to the figure 2 , its constituent parts are in the position shown on the Figures 4a , 4b and 5 . More specifically, the nose 392b of the retaining lever 392 is located between two columns of the column wheel 462 under the effect of the spring F392, so that the retaining wheel 393 does not engage 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 toothing 391c.
  • the hammer 36 under the action of the spring F36, bears against the cam 38d.
  • the wheel 38 of the minute hand rotates, accordingly, 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 rotates the lever 501, but without acting on other parts.
  • the mechanism thus found the state A represented on the figure 4a .
  • the pivoting of the body 461a brings its pin 461 h in the groove 501 b of the zeroing lever 501.
  • the connecting member that forms the player 42 controlled by the control device 48 through the hammer 503, goes from the deactivated state to the activated state.
  • the mechanism is then in the position shown on the figure 4d , which corresponds to state C of the figure 2 .
  • the pin 461 m is offset relative to the pusher 28, which makes the latter inactive.
  • the body 461a whose position is defined by the finger 461d resting against a column of the cam 482, remains in this position, even if the groove 501b releases the pin 461 h. In other words, pressing the pusher 26 has no effect.
  • 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 of the figure 2 . This state, which is not shown in the drawing, allows an action on the pushers 24 and 26. A pressure on the pusher 24 causes the counting of the time, the mechanism returning to the state C by a new rotation of the cam 482 Thus, the chronograph clutch is reset, while the nose 503a of the hammer and the finger 461d bear against a column of the cam 482.
  • a similar process is applied to the hammer 503, so that the cam 40c is also subjected to a force which returns the second hand of timed second time to 20.
  • the chronograph mechanism is again in the defined state B above, so that it is possible to press the pusher 28, to return the mechanism to the state A, where the pushers 24 and 26 are inactive and where the minute hand 16 displays the minutes of time current. It is also possible to press on the pusher 24 to start a new measurement, the mechanism being in the C state.
  • the display device shown in figures 6 and 7 ensures the indication of the minute or the time. It is represented in the display position of the minute on the figure 7a , time on the figure 7b . It is intended to equip a watch movement comprising a frame 110, which carries a source of energy, in this case a cylinder 112, visible on the figure 6 , which drives a finishing gear, whose first moving wheel is a minute wheel 114.
  • the latter disposed at the center of the movement, pivots on the frame 110 about an axis AA and carries a frictionally mounted roadway 116 which meshes with a timer wheel 118, which drives an hour wheel 120.
  • the roadway 116 and the hour wheel 120 respectively perform a revolution in sixty minutes and in twelve hours, their angular position defining the state of the information to be displayed. They thus provide a function of information wheels.
  • the roadway 116 and the timer wheels 118 and 120 hours play the role usually devolved to the clockwork in classic watch movements, with the difference that none of these mobiles carry a needle.
  • the road more specifically comprises a tubular portion 116a, pierced from one side and frictionally engaged on the wheel of medium 114, a pinion 116b secured to the portion 116a and meshing with the timer wheel 118, a wheel board 116c, attached to the portion 116a, provided with a toothing 116d and carrying a hammer 122.
  • the latter is pivotally mounted on a post 123 driven into the board 116c.
  • This hammer is subjected to the action of a spring, schematically represented by an arrow F1 on the figures 7a and 7b , which tends to push the hammer 122 towards the axis AA.
  • the pavement 116 carries, free in rotation, a display unit 124 comprising, rigidly secured to each other, a board 124a provided with a set of teeth 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.
  • a display unit 124 comprising, rigidly secured to each other, a board 124a provided with a set of teeth 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 unit 124 is rotated by the roadway 116, via the hammer 122 and the cam 124d, making one revolution in sixty minutes. This situation is illustrated on the figure 7a .
  • the barrel 124c carries a needle 126 which, under the conditions described above, thus displays the current minute of 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 free to rotate on a tube 128 driven on 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 disposed on either side of the pivot point, the function of which will be specified below.
  • the board 120a has an annular portion-shaped opening 120c and extending at an angle of about 90 ° ( figures 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 a set of 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 into the thickness of the hammer 130, and arranged 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 ). This spring tends to keep the wheels 120 and 134 in a relative position such that the pin 132c is substantially at one end of the opening 120c.
  • the display device further comprises a wheel 136 comprising, rigidly secured to each other, a board 136a provided with a set of 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 needle 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 FIG. figure 7a .
  • the pin 132c moves in the opening 120c. During this movement, it bears 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 wheel 136 to rotate until it reaches 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 shank 130c is arranged in such a way that the pin 132c is held in its end 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 rotated.

  • the roadway 116 is not involved in this movement.
  • the hammer 122 is raised. In other words, the displacement of the wheel 132 with reference to the hour wheel 120 makes the display of the indication of minutes to that of hours.
  • the device according to the invention further comprises a control 140 slidably mounted on the frame 110, a rake 142 disposed in the vicinity, the same 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 on the figure 7a .
