  Within the framework of the present invention, the term “square wheel” (excluding the barrel wheel) refers to any toothed member for activating one or more hammer hammer ankle stones.

  1-4, a timing mechanism according to a preferred embodiment of the present invention for integration or addition to a timepiece, typically a watch movement, regulates an energy source 3 in a frame 1. A time train wheel train 2 connected to the speed machine 4 is included. The energy source 3 is typically an hour barrel that is directly connected to the wheel 2a of the hour wheel train and can be wound up by rotating the winding core 5. The core 5 is preferably a movement core that also serves to wind up the movement barrel. The governor 4 is a centrifugal governor (watt governor), for example. This is useful for adjusting the time tempo. A clutch lever 6 pivoting about a shaft 7 carries two pinions 8, 9 in relation to the lever 6. The pinion 8 rotates around the shaft 7 and is always directly connected to the pinion 10 integrated with the hourglass 11. Similarly, the pinion 8 is always meshed with a pinion 9 called a “clutch pinion”. In the first position of the clutch lever 6, that is, the linked position (see FIG. 1), the clutch pinion 9 is directly connected to the hour barrel 3 and the movement of the hour barrel 3 is beaten via the pinions 8 and 10. It meshes with the pinion 12 that transmits to the true 11. In the second position of the clutch lever 6, that is, the connecting / disconnecting position (see FIG. 2), the clutch pinion 9 does not mesh with the pinion 12, so that the hour striker 11 is freely rotated. In a variant, the clutch pinion 9 carried by the clutch lever 6 can mesh with the pinion of the hour wheel train or the vehicle in such a way that it receives the movement of the hour hammer barrel 3 via the wheel train. .

  The clutch lever 6 receives the action of a return spring 13 that attempts to pivot the lever in the connecting / disconnecting direction. The clutch lever 6 carries a pin 14 at one end thereof, and this pin is used for an hour strike trigger by the action of the return spring 13 when the hour strike mechanism is in a resting state (FIG. 3). It is maintained in a state supported by the first end of the lever 15, and thus the clutch lever 6 is maintained in its linked position. The hammer 15 for time-triggering trigger is maintained in a state of being supported by the surface 1a of the frame 1 by the all-or-nothing spring 17 at the rest position (see FIGS. 3 and 16). In order to release the pin 14 and thus the clutch lever 6 (FIG. 4) by pressing the tube 15a acting on the second end portion 16 of the hammer for trigger at this time in the axial direction. Can be activated. The tube 15a surrounds the core 5, and is connected to a crown-button (not shown) assembled to the end of the core 5. However, in a variant, the hour trigger lever 15 can be activated by a push button independent of the core 5. At an end different from the end carrying the pin 14, the clutch lever 6 is a pawl arranged to cooperate with a stop star wheel 19 integrated with one wheel 2b of the hour wheel train 2. (See FIGS. 1 and 2).

  Three square hole wheels 20, 21, and 22, which have the shape of a car, are assembled on the hourglass 11 (see FIGS. 5 and 6). These square wheel wheels include an hour wheel wheel 20, a quarter hour wheel wheel 21, and a minute wheel wheel 22. The hour square hole wheel 20 is integrated with the hour hammer 11 and the pinion 10. The quarter hour wheel 12 and the minute wheel are free to rotate in relation to the hour counter 11. The dentition of the square wheel 20, 21, 22 serves to activate the hitting ankle claw stones 23, 24, 25, 26 when activating the hammer 27 that strikes and excites the gongs 29, 30 themselves. The ankle pallet stones are the hour ankle pallet stone 23, the first quarter hour ankle talc stone 24 coaxial with the ankle pallet stone 23, the minute ankle talc stone 25, and the second quarter hour coaxial with the minute ankle talc stone 25. Ankle claws stone 26 is included. Each ankle claw stone group 23-24 and 25-26 is arranged to activate a respective hammer 27, 28, which is arranged to strike a respective gong 29, 30, and two gongs 29 , 30 generate different sounds. The hour wheel 20 includes one dentition having 12 teeth for activating the hour ankle claw stone 23 so that the hour ankle claw stone 23 activates a hammer 27 called “hour hammer”. The minute hole wheel 22 includes one dentition having 14 teeth for activating the minute ankle claw stone 25 so that the minute ankle claw stone 25 activates a hammer 28 called a “minute hammer”. The quarter hour wheel 21 has three teeth for activating the two quarter hour ankle claw stones 24 and 26, respectively, so that the quarter hour ankle claw stone 24 alternately activates the hour hammer 27 and the minute hammer 28. Including two dentitions.

  The hour, quarter hour and minute wheel 20, 21, 22 are respectively integrated with the hour, quarter hour and minute pinions 31, 32, 33 (see FIG. 5). The hour pinion 31 is directly connected to the dentition of the hour tooth cage 34 (FIGS. 6 and 7). The quarter-time pinion 32 is directly connected to the dentition of the quarter-hour toothpaste 35. The minute pinion 33 is directly connected to the dentition of the minute tooth cage 36. The quarter-hour and minute toothpicks 35, 36 pivot about the same axis 37. The hour toothpaste 34 preferably pivots about an axis 38 that is completely different from the pivoting axis 37 of the quarter hour and minute toothpicks 35, 36, but in a variant, the quarter hour and minute toothpicks. It can be considered that it can pivot about the same pivot axis 37 as 35 and 36. An hour antenna shaft 39 is assembled so as to pivot about the pivot shaft 38 of the hour tooth cage 34. The pawl 40 of the hour antenna 39 is arranged to cooperate with the hour cam 41 (seen in FIG. 1). A pin 42 (see FIG. 9) carried by the hour antenna 39 and engaged in the opening 43 of the hour tooth 34 defines the range of relative angular displacement between the hour antenna 39 and the hour tooth 34. . The quarter-time antenna shaft 44 is assembled so as to pivot about the pivot shaft 37 of the quarter-hour toothpaste 35 and the minute toothpaste 36. The claw 45 of the quarter hour antenna 44 is arranged to cooperate with the quarter hour cam 46 (see FIG. 7). A pin 47 (see FIG. 13) carried by the quarter hour toothpaste 35 and engaged in the opening 48 of the quarter hour antenna shaft 44 is a relative angular displacement range between the quarter hour antenna shaft 44 and the quarter hour tooth tooth 35. Is defined. The split antenna shaft 49 is integrated with the split toothbrush 36, and preferably forms a monoblock with the split toothbrush 36 (see FIG. 6). The claw 50 of the minute angle shaft 49 is arranged to cooperate with the minute cam 51 (see FIG. 12). The hour, quarter and minute cams 41, 46, 51 are of the conventional type and are driven by a movement in a conventional manner. The quarter hour and minute cams 46, 51 pivot about the same axis, which can be the axis of the second true barrel of the movement. The hour cam 41 is preferably not coaxial with the quarter-hour and minute cams 46,51. Hour, quarter-hour and quarter tooth 34, 35, 36 are each return springs 52, 53, 54 (FIG. 6 and FIG. 6) which attempt to rotate the tooth in the direction in which the nail approaches the corresponding antennal shaft of the corresponding cam. 7).

  The hour tooth 34 carries a quarter-time trigger lever 55 that pivots about an axis 56 (see FIGS. 6 and 7). The hour feeler shaft 39 and the quarter hour trigger lever 55 are connected by a spring 57, which keeps these two parts 39, 55 in contact with each other. The quarter hour trigger lever 55 is arranged to cooperate with a quarter hour insulator 58 assembled on the frame 1 of the hour mechanism. The quarter-hour insulator 58 is assembled so as to pivot about the shaft 59, and its angular movement is limited by the pin 60 fixed to the frame 1 and engaged in the opening 61 of the quarter-time insulator 58. Is done. The quarter-hour insulator 58 carries a pin 62 that serves as a stop for the quarter-tooth toothbrush 35 at a moment in the rest position of the quarter-hour insulator 58. The quarter-time insulator 58 is subjected to the action of a return spring 58a that attempts to maintain the insulator in its rest position.

  The quarter-time antenna shaft 44 includes a claw 63 disposed at the end opposite to the end defining the quarter-time claw 45 so as to activate the first clutch control lever 64 (FIG. 13). The first clutch control lever 64 is assembled on the quarter hour tooth hook 35 and receives the action of a return spring 65 that keeps the lever in contact with the claws of the quarter hour antenna shaft 44. The clutch control lever 64 is arranged so as to start the second clutch control lever 66 assembled on the frame 1. The second clutch control insulator 66 defines a fork 67 that houses the pin 14 carried by the clutch lever 6.

  The quarter hour toothbrush 35 and the split toothbrush 36 are assembled to pivot on the quarter hour toothbrush 35 and the second half of the minute toothbrush 36 to integrate the quarter hour and minute toothbrushes 35,36. The teeth 69 that are arranged to cooperate with the tooth row 70 are connected to each other by means of a helix or hook 68 (see FIG. 8). The spring 68 is subjected to the action of a return spring 68a that attempts to maintain the teeth 69 in the tooth row 70. A helical stopper 71 fixed on the frame 1 causes the helical 68 to pivot against the action of its return spring, thus causing the teeth 69 to escape from the dentition 70 and the integration of the quarter and quarter teeth 35, 36. Is arranged to cooperate with another tooth 72 of the chisel 68 (see FIG. 10).

  The hour and quarter hour wheel 20, 21 is supported by the quarter hour wheel 21 by means of a lever 73 that is assembled in a manner that pivots in relation to the quarter hour wheel 21 about a shaft 74. They are connected to each other (see FIG. 14). The insulator 73 carries a driving pin 75 arranged so as to cooperate with the stepped surface of the hour wheel 20. The stepped surface extends in the plane of the hour wheel 20, that is, in a plane perpendicular to the common rotation axis of the wheel 20, 21. Follow the curve and connect to the center. The stepped surface defines a footboard or step portion 76 and a riser 77. Each tread portion 76 is substantially coaxial with the rotation axis of the square wheel 20, 21, but is located at a different radial position from the other tread portions. The insulator 73 extends in a plane perpendicular to the rotation axis of the square wheel 20, 21 and pivots. The drive pin 75 extends parallel to the axis of rotation so that it can cooperate with the stepped surfaces 76, 77. The drive pin 75 similarly includes an angular positioning surface 79 of an insulator 73 that extends along a curve that matches the aforementioned curve when the hour wheel 20 is in a predetermined angular position and is secured to the frame 1. It is also possible to cooperate with the made lever stopper 78 (see FIG. 15). The lever 73 is subjected to the action of a return spring 80 that attempts to pivot the lever 73 in the counterclockwise direction of FIG. The return spring 80 preferably forms a monoblock with the insulator 73 as shown, and is assembled on the quarter hour wheel 21 at one end 80a thereof. For example, the end 80a is assembled so as to freely rotate around one pin 80b fixed on the quarter hour wheel 21.

  The timing mechanism functions as follows.

  In the resting state of the hour driving mechanism, the clutch lever 6 is in its linked position (see FIG. 1), and its pawl 18 is outside the tooth row of the stop star wheel 19, and the hour driving barrel 3, The train wheel 2, the square hole wheels 20, 21, 22 and the toothed wheels 34, 35, 36 are immovable. The hour toothbrush 34 is maintained in contact with the pin by the force of the hour hammer barrel 3 (see FIG. 7), and thus the hour hammer barrel 3 cannot be unwound. The quarter hour wheel 21 is held by the hour wheel 20 via a lever 73, and a driving pin 75 of this lever is supported by one of the kick upper portions 77 (see FIG. 15). The split toothbrush 36 is held by the quarter hour toothpaste 35 via a tooth 68 having teeth 69 engaged in the dentition 70 (see FIG. 8).

  When the user presses the crown button and thus the tube 15a surrounding the winding core 5 (see FIG. 4), the hour trigger lever 15 no longer holds the pin 14 of the clutch lever 6, so that the clutch lever It pivots under the action of the return spring 13 until it comes into contact with the stopper 81 fixed to the head (see FIG. 2). Thus, the clutch lever 6 moves from the linkage position to the linkage position, and its pawl 18 enters the tooth row of the stop star wheel 19 to engage the hour wheel train 2 and hour hammer barrel 3. Stop and do not unwind the barrel for this time. Since the hour hammer 11 is no longer connected to the hour barrel 3, the hour, quarter hour and minute tooth rings 34, 35, 36 fall under the action of their return springs 52, 53, 54, The quarter hour toothpaste 35 is stopped by the pin 62 of the quarter hour insulator 58 during the stroke (see FIG. 7). Since the split toothbrush 36 is linked to the quarter hour toothpaste 35 by a helix 68, the split toothbrush 36 is likewise stopped during the stroke. Due to the cooperation between the quarter-hour trigger lever 55 and the hour antenna shaft 39, the hour tooth drop 34 moves the hour antenna shaft 39 in the direction of the hour cam 41. The claw 40 of the hour antenna 39 contacts the hour cam 41 and acquires information about the number of times to be beaten. The hour tooth 34 continues its stroke, and since the quarter hour trigger lever 55 is in contact with the hour antenna shaft 39, the quarter hour trigger lever 55 is rotated and rotates the quarter hour insulator 58 itself. (See FIG. 9). The movement of the hour toothbrush 34 stops when the wall of the opening 43 comes into contact with the pin 42 of the hour antenna shaft 39.

  The rotation of the quarter hour insulator 58 releases the quarter hour toothpaste 35 (see FIG. 9). At this time, the quarter toothpaste 35 starts to fall under the action of the return spring 53. Due to the contact between the first clutch control lever 64 and the claw 63 of the quarter-time antenna shaft 44, the quarter-time antenna shaft 44 pivots in a direction to bring the claw 45 closer to the quarter-time cam 46. During this drop of the quarter toothpaste 35, the second tooth 72 of the pick 68 contacts the surface 82 of the pick stopper 71, and then (unless it is not necessary to beat any quarter), The stopper 71 is slid on the surface 83 (see FIG. 10), so that the helix 68 is pivoted against the action of its return spring, and the first tooth 69 escapes from the tooth row 70. Thus, the split toothbrush 36 is released from the quarter toothbrush 35 and can be dropped under the action of the return spring 54. The claws 45 of the quarter hour feeler shaft 44 and the claws 50 of the minute feeler shaft 49 are in contact with the quarter hour cam 46 and the minute cam 51, respectively, to obtain information about the number of quarter hours and minutes to be beaten ( 11 and 12). It is possible that the claw 50 of the minute antenna shaft 49 may come into contact with the minute cam 51 before the helix 68 is removed from the dentition 70. In that case, the toothpick 68 will be disengaged on the dentition 70 so that the quarter hour toothpaste 35 can continue its stroke so that the quarter hour antenna shaft 44 can obtain information about the quarter hour cam 46. it can. When the quarter hour feeler shaft 44 comes into contact with the quarter hour cam 46, the quarter hour toothpick 35 still continues its stroke and the first clutch control lever 64 is in contact with the quarter hour feeler shaft 44. The first clutch control lever 64 is rotated against the action of the return spring 65 to rotate the second clutch control lever 66 itself. The drop of the quarter hour tooth hook 35 stops when the pin 47 of the quarter hour tooth hook 35 contacts the wall of the opening 48 of the quarter hour antenna 44 (FIG. 13). At the end of the stroke of the quarter toothbrush 35 (see FIG. 14), the drive pin 75 contacts the lever stopper 78 and is guided by the positioning surface 79 of the lever stopper 78, on which time is beaten. Depending on the number of quarter-hours to be positioned, it will be located in a radial position (relative to the axis of the square wheel 20, 20, 22) corresponding to one of the four risers 77. Due to the displacement of the drive pin 75 on the positioning surface 79, the insulator 73 causes its shaft 74 to oppose the action of its return spring 80 which keeps the drive pin 75 supported by the positioning surface 79. It is pivoted as a center.

  During the fall of the toothpaste 34, 35, 36, the square wheel 20, 21, 22 activates the ankle claw stones 23-26 in a direction in which the hammers 27, 28 cannot be activated.

  As the second clutch control lever rotates at the end of the fall of the quarter tooth hook 35, the clutch lever 6 is returned to its linked position while driving the pin 14 (see FIGS. 13 and 1). At this moment, the hour hammer 11 is again coupled to the hour barrel 3 and the force of the hour barrel 3 rotates the hour wheel 20 in another direction, thus causing the hour tooth pin 34 to move the pin 60. Until it comes back and abuts against the action of the return spring 52 (see FIG. 7). This rotation of the hour wheel 20 that triggers the rise of the hour wheel 34 activates the ankle claw stone 23 when it itself activates the hammer 27 to beat the hour. The angular amplitude of the displacement of the hour wheel 34 and the hour wheel 20 and thus the number of teeth of the hour wheel 20 encountered with the hour ankle claw stone 23 is the place where the claw 40 of the hour antenna shaft 39 is on the hour cam 41. As a result, it depends on the angular position of the hour cam 41. This angular amplitude of the hour wheel 34 and hour wheel 20 corresponds to the number of hits that should be hit to indicate the hour.

  During this rotation of the hour wheel 20, one of the upper portions 77 located at the same radial position as the driving pin 75 comes into contact with the pin 75 and presses this pin (see FIG. 15). The wheel 20 is capable of driving the quarter hour wheel 21 (and more generally all the chains 21, 32, 35) against the action of the return spring 53 of the quarter tooth tooth 35. During this driving, the driving pin 75 is maintained in a state where it is supported by the tread plate portion 76 corresponding to the above-mentioned kicking portion 77 by the return spring 80. The quarter hour wheel 21 activates the first and second quarter hour ankle stones 24 and 26 at this time by means of its two dentitions. After that, the hammers 27 and 28 are activated as many times as the number of quarter-hours to be beaten. Thanks to the insulator 73, on the stepped surfaces 76, 77 and the positioning surface 79, the elapsed time between the end of the hour and the beginning of the quarter hour is the number of quarter hours to be hourly. Regardless. Compared to conventional devices that equalize dead time between hourly and quarter-time beats, such as the device described in US Pat. The devices 73, 76, 77, 79 have the advantage of eliminating the risk of a gear stop between the pawl and the dentition. Such devices 73, 76, 77, 79 are provided in the structure in which the hour and quarter hour gears 34, 35 are coaxial, rather than between the hour wheel 20 and the quarter hour wheel 21. It is pointed out that it can be used between the toothpaste and the quarter hour toothpaste 35.

  During driving of the quarter hour wheel 21 by the hour wheel 20, the tooth 68 carried by the quarter tooth wheel 35 escapes from the tooth stopper 71 and engages in the tooth row 70 of the minute tooth wheel 36. Thus, it is possible for the quarter toothpaste 35 to drive the minute toothpaste 36. At this time, the minute wheel 22 driven by the minute toothbrush 36 activates the minute ankle claw stone 25 by the tooth row, and this ankle claw stone 25 is moved after all the quarter-hours are finished. The hammer 28 is activated a number of times corresponding to the number of minutes to be beaten. The tooth space of the dentition 70 in which the teeth 69 of the helix 68 engage depends on the number of minutes to be beaten. Thus, the elapsed time between the end of the quarter hour and the beginning of the minute is the same, regardless of the number of minutes to be beat.

  In a variant of the invention, a device similar to the devices 73, 76, 77, 79 (however, the number of risers 77 is adapted) is between the quarter hour wheel 21 and the minute wheel 22. Or, between the quarter toothpaste 35 and the split toothpaste 36, this is used in place of the helical device 68 and the dentition device 70.

  Due to the coaxial arrangement of the hour, quarter-hour and minute wheel 20, 21, 22, the hour mechanism is compact in the plane of the watch. Moreover, the depth of penetration of the ankle claw stones 23, 24, 25, 26 in the corresponding dentition of the square wheel can be the same, and thus the activation of the hammers 27, 28 can be optimized.

  In the present invention, depending on the gear ratio between the pinions 31, 32, 33 corresponding to the respective tooth sets 34, 35, 36, small angular displacements of the tooth sets 34, 35, 36 cause the corresponding square wheels 20, 21. , 22 causes a large angular displacement, so that the external dimensions of the time-strike mechanism in the plane of the watch are extremely compact. Thus, the angular movement of the toothpaste 34, 35, 36 is smaller than the movement of the toothed wheel wheel according to the current state of technology (Patent Document 1 and Patent Document 2). The fact that the toothed teeth 34, 35, 36 are not necessarily coaxial, unlike the toothed teeth 20, 21, 22 and the state-of-the-art toothed wheel, provides greater freedom in the design of the mechanism.

  Similarly, the same part, that is, the clutch lever 6 connects / disconnects the hour driving mechanism, and the hour driving barrel 3 is connected to the lever via a locking member (claw 18) integrated with the lever. It is also pointed out that it fulfills the dual function of locking in. This feature prevents the unwinding of the hourglass barrel 3 in a simple manner during the fall of the toothpaste 34, 35, 36 and the corresponding rotation of the square wheel 20, 21, 22. Preferably, as shown, the locking member forms a monoblock with the clutch lever 6.

  In a variant of the invention, the square wheel 20, 20, 22 may have a toothed shape rather than a car. Nevertheless, in the present invention, the square wheel is provided on the ground that sufficient rigidity can be imparted to the square wheel to ensure good cooperation between the tooth of the square wheel and the ankle claw stone. It is preferable to carry out 20, 21, 22 in the form of a car.

  According to another advantageous feature of the invention, the hour-handing mechanism is adapted to use the energy stored in the hourglass barrel 3 after the acquisition of information about the cams 41, 46, 51 and the square wheel wheels 20, 21, 22 and Includes a device to prevent time-triggered triggering when it is not sufficient to ensure the return of the toothpaste 34, 35, 36. This device includes a locking lever 84 maintained at a rest position with respect to a stopper 85 fixed to the frame 1 by a return spring 86 (see FIG. 16). In the rest position, the latching lever 84 is outside the path followed by the pin 14 when the connection position / disconnection position of the clutch lever 6 is changed. Accordingly, the locking lever does not hinder the movement of the clutch lever 6. However, the locking lever 84 can be pivoted in the position shown in FIG. 17 where its end acts as a stopper that prevents the movement of the pin 14 toward the coupling and disengagement of the clutch lever 6. Thus, in this position of the locking lever 84, activation of the trigger lever 15 by the crown button has no effect on the clutch lever 6, so that the clutch lever 6 remains in its linked position and therefore triggers the hour. do not do.

  The member that controls the pivoting movement of the locking lever 84 is a power reserve display wheel. The power reserve indicator wheel 87 includes an arcuate opening 88 that accommodates a pin 89 fixed to the frame 1. The opening 88 and the pin 89 have two limit positions for the power reserve display wheel 87, that is, a position substantially corresponding to a state in which the spring of the hourglass barrel 3 is completely wound up and a spring of the hourglass barrel 3 A position that substantially corresponds to the fully unwound state is defined. The power reserve display wheel 87 carries an indicator (not shown) such as a hand for indicating the power reserve of the time-setting mechanism on the dial of the watch. In the conventional manner, the power reserve indicator wheel 87 is driven by the output of a differential gear having two inputs: the true of the hour barrel 3 and the teeth of the barrel.

  When the hourglass barrel 3 is sufficiently wound up (FIG. 16), the power reserve indicator wheel 87 does not act on the locking lever 84, so that the locking lever remains in its rest position. When the hourglass barrel 3 does not contain enough energy to activate the hourglass (FIG. 17), the power reserve display wheel 87 has a protruding portion 90 of the wheel 87 that contacts the locking lever 84, The lever is pivoted against the action of its return spring 86 and is in one angular position to guide the lever to a position where the lever prevents pivoting of the clutch lever 6 toward the connecting / disconnecting position. The indicator carried by the power reserve indicator wheel 87 informs the user that the user has to wind up the hourglass barrel 3. As soon as the hourglass barrel 3 is fully wound, the projecting portion 90 moves away from the locking lever 84 so that the locking lever can return to a rest position outside the path of the pin 14. .

  According to yet another advantageous feature of the invention, the hour mechanism includes a device for preventing the hour trigger when the time of the watch is set. Indeed, when triggered by time adjustment, the rotation of the quarter and minute cams 41, 46, 51 comprises any device for preventing the antennal shafts 39, 44, 49 from contacting the cams during time adjustment. Otherwise, damage may occur in the timing mechanism. Referring to FIG. 18, the device used in the present invention can be activated by a time setting mechanism setting lever 92 that cooperates with the core 5. When the winding core 5 including the stopping lever 91 is in the pressing position, the locking lever 91 is outside the path of the pin 14 carried by the clutch lever 8 (FIG. 18). In this state, the activation of the crown button triggers an hourly strike (if the power reserve is sufficient). When the winding core 5 is in its pulling position, that is, in its time setting position, the locking lever 91 pivots the clutch lever toward its connecting / disconnecting position with its end serving as a stopper for the pin 14. Another angular position is taken to prevent (see FIG. 19). Thus, in this position of the locking lever 91, the activation of the trigger lever 15 by the crown button has no effect on the clutch lever 6, so that the clutch lever 6 remains in its linked position and therefore is timed. Do not trigger.

  According to yet another advantageous feature of the invention, the hour-handing mechanism allows the hourglass barrel 3 to be rolled up in the same simple manner as the movement barrel shown by the mark 93, One device shown in 20 and 21 is included. In this device, when the winding core 5 is in its pressed position, the rotation of the core in one direction (for example, clockwise direction) winds up the hour barrel 3 and in the other direction (for example, counterclockwise direction). The rotation of the wick rolls up the movement barrel 93. This device includes an input wheel 94 that can be driven in either direction by the core 5. For this purpose, the input wheel 94 is driven through the longitudinal teeth by a pinion wheel (as seen in FIG. 18) assembled around the core 5 and rotationally integrated with the core 5. The winding pinion 96 meshes with the round hole wheel 95 meshing with itself. The input wheel 94 carries at least one helix on each of its two sides. A helix 98 carried by the lower surface of the input wheel 94 (see FIGS. 21 and 22) cooperates with a dentition having pinion 99 spur teeth integrated with the first output wheel 100. The helix 101 (FIGS. 21 and 23) carried by the upper surface of the input wheel 94 cooperates with a tooth row having a spur tooth of the pinion 102 integrated with the second output wheel 103.

  The first output wheel 100 is a hoisting wheel for the hour barrel 3. This output wheel actually meshes with the square hole wheel 104 of the hour barrel 3 through the idle gear 105. The second output wheel 103 is a winding wheel of the movement barrel 93. This car actually meshes with the square hole wheel 106 of the movement barrel 93 via the idle gears 107 and 108. The first and second output cars 100 and 103 rotate only in one direction because of the hose 98 and 101, and the rotation direction of the first output car 100 is different from the direction of the second output car 103. The opposite is the case. When the input wheel 94 is driven in the first direction by the winding core 5, the vehicle drives the pinion 99 by the lever 98 and eventually the first output wheel 100 to wind up the hour barrel 3. . During this movement, the helix 101 is disengaged and therefore does not drive the second output wheel 103, which remains stationary. When the input wheel 94 is driven in the other direction by the winding core 5, the input wheel 94 drives the pinion 102 and then the second output wheel 103 by the lever 101 to wind up the movement barrel 93. During this movement, the hail 98 is disengaged and therefore does not drive the first output wheel 100, which remains stationary.

  It is pointed out that this hoisting device of the barrel 3, 93 is very compact in the plane of the watch because the input wheel 94 (bidirectional) and the two output wheels 100, 103 (unidirectional) are coaxial. Is done.

  24 to 26 show a clutch device according to another embodiment. 1 and 2, the clutch device includes a clutch lever 6 and pinions 8 and 9 carried by the lever. The clutch device illustrated in FIGS. 24 to 26 includes a lever 110 and a differential gear device 111 installed between the hour hammer barrel 3 and the hour hammer 11.

  The differential gear unit 111 includes a sun gear 112, a planetary gear coupling link 114, and a sun pinion 115 integrated with a link wheel 113 that meshes with the hour barrel 3 in a coaxially arranged state (FIG. 26). reference). The sun gear 112 constitutes the input side of the differential gear device 111. The sun gear includes internal teeth that mesh with at least one (preferably three) planetary gears 116 carried by the planetary gear coupling link 114. In a variant, the sun gear 112 may be a pinion that meshes with one or more planetary gears 116 and their surrounding teeth. Each planetary gear 116 is coaxial and integral with one planetary gear 117 located on the other side of the planetary gear coupling link 114. Each planetary gear 117 meshes with the sun pinion. This sun pinion constitutes the output end of the differential gear unit 111 and meshes with the pinion 10 of the time-honored true 11 via, for example, the idle gear 118.

  The lever 110 pivots at one point 119 and is subjected to the action of a return spring 110a that attempts to press the lever against the stopper 110b. The lever 110 cooperates with the stop star wheel 19 integrated with the wheel 2b of the hour wheel train 2 in accordance with the clutch lever of FIGS. Or the latching claw 120 for canceling | releasing latching is included. Similarly, following the lever 6 carrying the pin 14, the lever 110 cooperates with the time-trigger trigger lever 15 illustrated in FIGS. 3 and 4 or with the time-trigger trigger member 122 described below as a modified form. It carries a pin 121 for working.

  The lever 110 further carries a locking finger 123 that is engaged in or disengaged from the peripheral tooth row of the planetary gear coupling link 114 depending on the position of the lever 110. More precisely, at the first position of the lever 110, that is, at the linkage position, the locking claw 120 does not lock the hour barrel 3, but on the other hand, the locking claw engaged with the tooth row of the planetary gear coupling link 114. At this time, the finger 123 locks the barrel 3 for driving. Therefore, the hour barrel 3 can rotate and drive the input wheel 112 via the link wheel 113, and the input wheel 112 can be driven by the sun pinion 115 and the planetary gears 116 to 117 via its internal teeth and the planetary gears 116 to 117. Rotate the hit 11 In the second position of the lever 110 or the connecting / disconnecting position, the locking claw 120 locks the hour barrel 3, while the locking finger 123 does not lock the planetary gear coupling link 114. Since the hour barrel 3 is locked, the input wheel 112 is also locked. Since the planetary gear coupling link 114 can freely rotate, the planetary gears 116 to 117 can drive the planetary gear by rolling on the internal teeth of the input wheel 112. Accordingly, the hour setting 11 is released from the hour barrel 3 and the hour gear, the sun pinion 115, and the planetary gear coupling link 114 are rotated to return the hour, quarter hour, and minute tooth rings 34, 35, and 36. It can be rotated under the action of the springs 52, 53, 54.

  The second configuration, that is, the configuration in which the locking finger 123 does not lock the planetary gear coupling link 114 and the locking claw 120 locks the hour barrel 3 releases the lever 110 and its return spring 110a. This corresponds to the information acquisition stage triggered by the activation of the hourly trigger lever 15 or the hourly trigger member 122. The first configuration, that is, the configuration in which the locking finger 123 locks the planetary gear connecting link 114 and the locking claw 120 does not lock the hour barrel 3 corresponds to the time-stepping stage that occurs as a result of information acquisition. To do.

  In the embodiment shown, the locking finger 123 is in the form of a retrofit component fixed to the lever 110. However, in a variant, this may take the form of a lever 110 and a monoblock, as do the locking pawls 120 preferably.

  A time-trigger trigger member 122 that replaces the time-trigger trigger lever 15 illustrated in FIGS. 3 and 4 in one variant is obtained as a result of disassembling the lever 15 into two parts. More precisely, the timing trigger member 122 includes two levers 124, 125 that pivot at points 126, 127, respectively, against which the levers 124, 125 against the stoppers 130, 131 are provided. The return springs 128 and 129 to be pressed act respectively. An insulator 125 called “control insulator” is controlled by the tube 15a in the same manner as the hourly trigger insulator 15 (see FIGS. 3 and 4). A lever 124 called a trigger lever serves as a function of an end portion of the hour trigger lever 15, that is, a function of cooperating with the pin 121 in order to hold the lever 110 in a linked position. The control lever 125 pivots the trigger lever 124 against the action of the return spring 128, thus releasing the lever 110, so that the pawl 133 of the trigger lever 124 is activated when the control lever 125 is activated. A retractable claw 132 in contact with the. In the second stage of the movement of the control lever 125, the pawl 132 loses contact with the pawl 133, so that the trigger lever 124 immediately returns to its initial position under the action of its return spring 128. Thus, even if the control lever 125 remains in the activated state (the user keeps pressing the crown button or push button), the lever 110 is surely maintained in its linked position during the time-stamping phase after information acquisition. Can be guaranteed. Since the claw 132 can be retracted, the control lever 125 can return to its initial position even though the claw 133 exists on the trajectory of the claw 132. Of course, such a beat trigger member 122 may be used with the clutch devices 6, 8, 9 illustrated in FIGS.

  27 and 28 show a clutch device according to yet another embodiment. The clutch device illustrated in FIGS. 27 and 28 is a vertical type. This clutch device includes a lever 135, a vertical clutch rotator 136 positioned between the hourglass barrel 3 and the hourglass true 11, and a control member that acts on the vertical clutch rotator 136 and is itself controlled by the lever 135. 137.

  The lever 135 carries a pin 138 and a locking claw 139 having the same functions as the pin 121 and the locking claw 120 illustrated in FIG. The lever 135 similarly carries a stopper finger 140 and a control finger 141. Following the lever 110, the lever 135 is subjected to the action of a return spring 142 that presses the lever against a stopper (not shown).

  The vertical clutch rotating body 136 includes a first wheel 143 that meshes with the hour barrel barrel 3 in a coaxially arranged state, a second wheel 144 that meshes with the pinion 10 of the hour hammer 11, and a Breguet tooth row 145a. A third car 145 having a third car 145 (which is fixed to the second car 144) and a fourth car 146 having a Breguet tooth row 146a (the fourth car 146 is a first car) 143, which is rotationally integrated with respect to H.143, but can freely translate in the axial direction. The spring 147 presses the Breguet tooth row 146a of the fourth wheel 146 against the Breguet tooth row 145a of the third wheel 145, thereby rotationally integrating the first wheel 143 and the second wheel 144, thus An attempt is made to connect the hourglass barrel 3 to the hourglass true 11.

  The control member 137 includes a spring 148 and a fork 149 secured to the free end of the spring 148, and the two teeth 150 of this fork 149 (only one of these teeth can be seen in the drawing). The fourth wheel 146 can be displaced in the axial direction against the action of the spring 147 when the spring 148 is bent, being supported symmetrically by the rim 151 of the fourth wheel 146. The deflection of the spring 148 and thus the axial displacement of the fourth wheel 146 is controlled by the control finger 141 of the lever 135 acting on the inclined plane 152 of the fork 149. In one variation, the control member 137 may be in the form of a single piece.

  The lever 135 can assume a first position and a second position (not shown) corresponding to the positions illustrated in FIGS. In the first position of the lever 135, the control finger 141 leaves the fork 149 in the rest position, in which the fork does not touch the fourth wheel 146 and the locking claw 139 engages the hourglass barrel 3. I will not stop. This first position corresponds to the connected state of the clutch device, thus making it possible to develop the timing stage that occurs as a result of information acquisition. In the second position of the lever 135, the control finger 141 cooperates with the inclined plane 152 to deflect the spring 148, and the fourth wheel is thus removed from the Breguet tooth row 145a of the third wheel 145 by the fork 149. Escape. Therefore, the second wheel 144 can freely rotate in relation to the first wheel 143, and the first wheel 143 is locked by the action of the locking claws 139 with respect to the star wheel 19. This second position of the lever 135 corresponds to the engaged / disengaged state of the clutch device and allows the information acquisition stage to be developed.

  The unidirectionality of the Breguet teeth row 145a, 146a is not utilized in the present invention. The spur shape of these dentitions facilitates clutch engagement by avoiding the risk of locking that can cause contact between the tips of the teeth of the wheels 145 and 146. In a variant, the Breguet dentition 145a, 146a can be replaced with a conventional vertical dentition (bidirectional).

  Stopper finger 140 of lever 135 enters under fourth wheel 146 as shown in FIG. 28 when lever 135 is in its first position. This stopper finger 140 prevents the fourth wheel 146 from losing contact with the third wheel 145 despite the action of the spring 147 when the watch is impacted. Thus, in this embodiment of the invention, the lever 135 locks / unlocks the hourglass barrel 3, controls linkage / disengagement, and prevents engagement / disengagement in the event of an impact 3 Fulfills one function.
