Description

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to an indicator correction mechanism, an information indicating mechanism, a movement, and a timepiece.

2. Description of prior art

[0002] In the prior art, timepieces including an information indication mechanism for indicating information other than the time, for example the day of the week, the date, or a moon phase, are known. A timepiece equipped with this type of information indicating mechanism generally includes a correction mechanism for correcting various items of information indicated as required.

[0003] For example, JP-A-2015-219240 (PTL 1) discloses a correction mechanism (modification mechanism) for the correction of a date indicator on which a date is indicated and a moon phase indicator on which a moon phase is indicated.

[0004] The correction mechanism mainly includes an oscillating plate pivoting around an axis under the action of the rotation of a winding stem actuated by a crown, a correction wheel pivotally mounted on the oscillating plate, and a plurality transmission wheels mounted on the oscillating plate and transmitting energy (that is to say an actuation torque in rotation) from the winding stem to the correction wheel.

[0005] The oscillating plate rotates around the pivot axis so as to move either towards a first position or a second position depending on the direction of rotation of the winding stem. The correction wheel meshes with internal teeth of the date indicator when the swash plate is located in the first position, and meshes with an intermediate wheel which meshes with the moon phase indicator when the swash plate is located in the second place.

[0006] Therefore, by rotating the winding stem in one direction, the swash plate can be moved to the first position, and the energy transmitted from the plurality of transmission wheels is used to rotate the correction wheel, and the date indicator can be corrected. By rotating the winding stem in the other direction, the swash plate can be moved to the second position, and the energy transmitted from the plurality of transmission wheels is used to rotate the correction wheel, and the indicator moon phase can be corrected via the intermediate wheel.

[0007] However, in a traditional correction mechanism such as that described above, it is necessary to assemble the correction wheel individually to the oscillating plate to adjust the date indicator and the moon phase indicator, as well that the plurality of transmission wheels to transmit energy to the correction wheel, and thus the number of components increases, which leaves room for improvement.

[0008] Since the date indicator and the moon phase indicator are corrected using a correction wheel arranged on the oscillating plate, the date indicator can be rotated directly using the correction wheel, but the moon phase indicator is difficult to turn without the interposition of one or more intermediate wheels. Therefore, the number of components also increases with respect to this aspect as well.

[0009] Moreover, since it is necessary to incorporate an intermediate wheel, the movement tends to become bulkier in the direction of the thickness, which prevents any reduction in thickness and compactness for the timepiece. involving such movement.

SUMMARY OF THE INVENTION

[0010] An object of the present patent application is to provide an indicator correction mechanism, an information indication mechanism, a movement, and a timepiece that can appropriately correct an indication while reducing the number of components and thus reducing its size and thickness. (1) An on-demand indicator correction mechanism includes: a tilt lever configured to be rotatable about a pivot axis and moveable between a first correction position and a second correction position; a first correction wheel configured to rotate about a first axis of rotation which is non-coaxial with the pivot axis, and which is arranged to approach or separate from a first indicator wheel on which first information is indicated, and approaching the first indicator wheel via the tilt lever to mesh with the first indicator wheel when the tilt lever is placed in the first correction position; a second correction wheel configured to rotate about a second axis of rotation which is non-coaxial with neither the pivot axis nor the first axis of rotation, and which is arranged to approach or separate from a second indicator wheel on which second information is indicated, and to approach the second indicator wheel via the tilt lever to mesh with the second indicator wheel when the tilt lever is placed in the second position corrective; and an adjustment transmission wheel rotatably mounted around the axis of rotation in a state of mesh with the first correction wheel and the second correction wheel, and arranged to transmit energy transmitted from the outside to the first wheel correction wheel and the second correction wheel, at least one wheel among the adjustment transmission wheel, the first correction wheel and the second correction wheel being assembled with the tilting lever so as to present a predetermined rotational resistance with respect to the latter, and the tilting lever rotating around the axis of rotation following the rotation of the adjustment transmission wheel, and, while it is positioned in the first correction position and in the second correction position, allows any of the wheels to rotate relative to the rocker lever when the rocker lever experiences a resistance that exceeds the rotational resistance.

[0011] In the indicator correction mechanism according to the present patent application, by rotating the adjustment transmission wheel under the impulse of an energy transmitted from the outside, the tilting lever can be pivoted around its pivot axis at the same time as the rotation of the adjustment transmission wheel, and can be moved to the first correction position or the second correction position.

[0012] By pivoting the tilting lever in the direction of the first correction position, the first correction wheel can approach the first indicator wheel and can mesh with the first indicator wheel. Until the tilt lever reaches the first correction position, the first correction wheel does not mesh with the first indicator wheel and moves following the rotation of the adjustment transmission wheel.

[0013] Since the first correction wheel can transmit the power transmitted from the adjustment transmission wheel to the first indicator wheel by meshing with the first indicator wheel, the first indicator wheel can be rotated . Accordingly, an indication of the first indicator wheel on which the first information is indicated can be corrected. When the tilting lever reaches the first correction position, the tilting lever is positioned in the first correction position, and can therefore no longer continue to pivot. Therefore, the tilting lever experiences a resistance exceeding the resistance in rotation, and the adjustment transmission wheel and the first correction wheel can be rotated while keeping the position of the tilting lever as it is. Accordingly, the indication of the first indicator wheel can be corrected appropriately.

Furthermore, by pivoting the tilting lever in the direction of the second correction position, the second correction wheel can approach the second indicator wheel and can mesh with the second indicator wheel. Until the tilt lever reaches the second correction position, the second correction wheel does not mesh with the second indicator wheel and moves following the rotation of the adjustment transmission wheel.

Since the second correction wheel can transmit the energy transmitted from the adjustment transmission wheel to the second indicator wheel by meshing with the indicator wheel, the second indicator wheel can be rotated. Accordingly, an indication of the second indicator wheel on which the second information is indicated can be corrected. When the tilting lever reaches the second correction position, the tilting lever is positioned at the second correction position, and can therefore no longer continue to pivot. Therefore, the tilting lever experiences a resistance exceeding the rotational resistance, and the adjustment transmission wheel and the second correction wheel can be rotated while keeping the position of the tilting lever as it is. Accordingly, the indication of the second indicator wheel can be corrected appropriately.

[0016] Thus, by pivoting the tilting lever, two correction wheels having different axes of rotation, that is to say, the first correction wheel and the second correction wheel, can move in a coordinated manner with each other, and can mesh directly with the first indicator wheel or the second indicator wheel to correct the indication. Therefore, it is not necessary to correct the indication of the first indicator wheel or the second indicator wheel via the intermediate wheel or the like as in the prior art, and the number of components can be reduced . Therefore, an indicator correction mechanism can be simplified and cost reduction can be achieved.

[0017] The tilting lever can be pivoted using an adjustment transmission wheel to which energy is transmitted from the outside; moreover, since the adjustment transmission wheel meshes with the first correction wheel and the second correction wheel, power can be directly transmitted from the adjustment transmission wheel to the first correction wheel and the second correction wheel . Therefore, the number of components can be effectively reduced in this area as well.

As described above, it is not necessary to correct the first indicator wheel or the second indicator wheel via the intermediate wheel or the like, so that it is not necessary to provide a space to place the intermediate wheel. Therefore, the size and the thickness can be reduced easily.

Since the first correction wheel and the second correction wheel can mesh directly with the first indicator wheel and the second indicator wheel, the first correction wheel and the second correction wheel are simply made. That is to say, since the first correction wheel has a shape meshing only with the adjustment transmission wheel and the first indicator wheel, the number of gear portions can be two, and a profile of tooth or the like can be designed easily and freely. Similarly, since the second correction wheel has a shape meshing only with the adjustment transmission wheel and the second indicator wheel, the number of gear portions may be two, and the profile of the teeth or the like can be designed easily and freely. Therefore, it is possible to provide an additional degree of freedom in the design of the first correction wheel and the second correction wheel. (2) The first correction wheel can be rotatably mounted on the tilting lever around the first axis of rotation.

[0020] In this case, the first correction wheel can move when the tilting lever pivots, and therefore in response to the pivoting of the tilting lever, the first correction wheel can appropriately approach and separate from the first indicator wheel. Therefore, when the tilt lever is positioned in the first correction position, the first correction wheel can properly mesh with the first indicator wheel. So the indication of the first indicator wheel can be corrected reliably and easily. Since the tilting lever and the first correcting wheel can be combined with each other or mounted on top of each other, the indicator correcting mechanism can be assembled easily and efficiently. (3) The first correction wheel can be guided along a guide groove so as to approach and separate from the first indicator wheel, and when rotated toward the first correction position, the tilting lever can move the first correction wheel so as to approach the first indicator wheel.

[0021] In this case, for example, since the first correction wheel can be guided along the guide groove formed in a platen or the like, the positioning of the first correction wheel can be stabilized easily, and the first correction wheel correction can move stably towards the first indicator wheel together with the pivoting of the tilt lever to the first correction position. Therefore, the first correction wheel can reliably mesh with the first indicator wheel, and the indication is easily corrected. (4) The tilting lever may have an insertion hole through which an axle of the first correction wheel is inserted, and when pivoted toward the first correction position, the tilting lever can move the first correction wheel so that the latter approaches the first indicator wheel using an inner edge of the insertion hole, and when pivoted toward the second correction position, the tilt lever can move the first correction wheel so as to separate it from the first indicator wheel using the inner edge of the insertion hole.

[0022] In this case, regardless of whether the tilting lever is pivoted in the direction of the first correction position or the second correction position, since the first correction wheel can be moved via a compression force using the hole d insertion, the first correction wheel can reliably approach and mesh with the first indicator wheel, and can reliably separate from the first indicator wheel to release the gear. (5) The second correction wheel can be rotatably mounted on the tilting lever around the second axis of rotation.

[0023] In this case, the second correction wheel can move as long as the tilting lever pivots, and therefore in response to the pivoting of the tilting lever, the second correction wheel can appropriately approach and be separated from the second indicator wheel. Therefore, when the tilt lever is positioned in the second correction position, the second correction wheel can properly mesh with the second indicator wheel. So the indication of the second indicator wheel can be corrected reliably and easily. Since the tilting lever and the second correcting wheel can be combined with each other or mounted on top of each other, the indicator correcting mechanism can be assembled easily and efficiently. In particular, when the first correction wheel is mounted integrally on the tilting lever, that is to say in one piece, the indicator correction mechanism can be assembled more efficiently. (6) The adjustment transmission wheel can rotate around the pivot axis in a first direction or a second direction when the winding stem is rotated, and the tilting lever can pivot in the direction of the first position of correction when the adjustment transmission wheel rotates in the first direction, and can pivot towards the second correction position when the adjustment transmission wheel rotates in the second direction.

[0024] In this case, by rotating the winding stem, the indication of the first indicator wheel and the second indicator wheel can be corrected separately while being freely selectable, and therefore corrections can be made. and used freely. (7) An indicator correction mechanism according to the present patent application includes the correction mechanism, the first indicator wheel and the second indicator wheel.

[0025] Since the information indication mechanism according to the application includes the indicator correction mechanism described below, the indications of the first indicator wheel and the second indicator wheel can be corrected appropriate as needed. Further, the size and thickness of the information indicating mechanism can be reduced, and the latter can be easily inserted into the movement or the like. (8) The first indicator wheel may be a date indicator indicating a date as the first information, and the second indicator wheel may be a 24-hour wheel to which a 24-hour hand is attached, indicating a second time zone as second information.

[0026] The information indicating mechanism according to the request can thus appropriately indicate the date, and can use the 24-hour hand to appropriately indicate the second time zone. Therefore, for example, dates, times, or the like of two countries (or cities) that vary due to a different time zone may be indicated appropriately. (9) A movement according to the present patent application includes the information indicating mechanism described above. (10) A timepiece according to the present patent application includes the movement described above.

[0027] In this case, since the information indicating mechanism described above is provided, it is possible to realize a movement and a timepiece which can appropriately indicate the first information and the second information, with high quality and high performance, with a reduction in compactness and thickness.

[0028] According to demand, the indications of the first indicator wheel and the second indicator wheel can be appropriately corrected while reducing the number of components, and the size and thickness can be reduced.

DESCRIPTION OF EMBODIMENTS

(First embodiment)

Hereinafter, a first embodiment according to the invention will be described with reference to the drawings.

In the present embodiment, there will be described, as an example of a timepiece, a mechanical timepiece implementing a direct drive structure for the seconds hand with four central hands among which an hour hand, a minute hand, a second hand, and a 24-hour hand (hour sub-hand) are arranged in the center of a movement which will also be described by way of example. On each drawing illustrating the present embodiment, for the sake of readability, some of the components of the timepiece may be omitted, and each timepiece component may be represented in a simplified form.

[0032] In general, reference is made to a "movement" to designate a mechanical body including a driving part of the timepiece. We refer to an “assembly” of the timepiece to designate a state in which a dial and hands are fixed to the movement and introduced into a case of the timepiece to constitute a finished product. Of the two sides of the plate which constitutes a support board for the timepiece, the side where the crystal covering the case of the timepiece is located (that is to say, the side where the the dial) is called the "back" of the movement. Of the two sides of the plate, the side where the back of the timepiece case is located (ie the side opposite the dial) is called the “front face” of the movement.

[0033] In the present embodiment, the direction going from the bottom (the front face) towards the dial is considered to be the forward direction and the direction opposite to it is referred to as the rear direction. Therefore, the thickness direction of the platen is a vertical direction. In the present embodiment, when centering on each axis, we refer to the clockwise direction of rotation when that axis is viewed from above as clockwise. and in the direction of rotation going counter-clockwise when this axis is seen from above as being counter-clockwise.

As illustrated in Figure 1, a timepiece assembly 1 according to this embodiment includes, in a timepiece case 3 configured with a bottom (not shown) and a crystal 2, a movement 10 (timepiece movement), a dial 4 having a scale indicating at least time information, and various hands pointing to the scale of dial 4.

The hands include a 24 hour hand 5 which rotates once every 24 hours and indicates the hours in a 24 hour format, an hour hand 6 which rotates once every 12 hours and indicates the hours in a 12-hour format, a 7 minute hand that rotates once every 60 minutes and indicates minutes, and an 8 seconds hand that rotates once every 60 seconds and indicates seconds.

The dial 4 has a date window 4a which constitutes an open window to clearly indicate a date 9 displayed on a date indicator 50, which will be described later. Consequently, the timepiece 1 according to the present embodiment can display a date in addition to the current time.

As illustrated in Figures 1 to 4, the movement 10 includes a plate 11 constituting a support plate for the movement 10.

[0038] A front gear train, an escapement which controls the rotation of the front gear train, and a speed regulator which controls the speed of the escapement are arranged on the front face of the plate 11. In each of these drawings, the escapement and the speed regulator are not shown.

The dial 4 (see Figure 1) is arranged on a bottom of the plate 11, and at least one going train including a floor 21, a minute wheel (not shown), an hour wheel 24, and a 24-hour wheel 40, an information indication mechanism 12, and an indicator correction mechanism 13 are arranged between the dial 4 and the plate 11. The dial 4 is arranged in a visible manner through the crystal 2.

[0040] The front gear train is arranged between a gear train bridge (not shown) arranged at the front of plate 11 and plate 11, and it is driven in rotation due to a drive torque exerted at the output of a barrel following the unwinding of its mainspring (not shown), and has the role of moving the 24-hour hand 5, the hour hand 6, the minute hand 7, and the second hand 8 The front wheel train mainly includes the barrel, a center wheel set 17 (see FIG. 4), a third wheel set, and a fourth wheel set 20. In each of the drawings, all of the parts constituting the barrel of the movement and the third wheel set are not shown.

Inside the barrel of the movement is housed by a mainspring (not shown) which is wound by a crown 14 and a winding stem 15 shown in Figure 1. The barrel rotates due to a force of elastic return which accompanies the disarming of the mainspring which tends to make it unwind. The center mobile 17, the third mobile, and the fourth mobile 20 rotate in this order when the barrel rotates.

[0042] The fourth mobile 20 is arranged coaxially with respect to a central axis C disposed at the center of the movement 10. A shaft of the fourth mobile 20 protrudes in the direction of the glass 2 in front of the dial 4, and is fixed to the seconds hand 8 at its upper end. Consequently, it is a form of direct drive according to which the seconds hand 8 moves directly following the rotation of the fourth mobile 20. Consequently, the seconds hand 8 represented in FIG. around the central axis C based on the basis of the rotation of the fourth mobile 20, and rotates at a rotational speed adjusted by the escapement and the speed regulator, that is, rotates once every 60 seconds.

[0043] The escapement includes an escapement wheel set meshing with the fourth wheel set 20 and rotating under the impulse of energy transmitted by the mainspring of the barrel and an anchor letting out and causing an escapement wheel set to rotate regularly, and controls the front gear train to perform a regular oscillation using a balance spring. The speed regulator primarily uses a hairspring (not shown) as the power source, and includes the hairspring which rotates back and forth (i.e. back and forth) at a constant amplitude (angle of oscillation) as a function of the output torque of the barrel.

As illustrated in Figure 4, the floor 21 constituting the timer is arranged coaxially with respect to the central axis C at the rear of the plate 11 (that is to say above), and can rotate around the central axis C. The roadway 21 includes a barrel pinion body 22 and is combined with the center wheel 17 in a state where a predetermined pressure contact force (friction force) is maintained. Consequently, the roadway 21 rotates around the central axis C together with the rotation of the center mobile 17.

[0045] When a relative rotational force exceeding the pressure contact force (frictional force) is exerted between the barrel pinion body 22 and the center wheel set 17, for example, when setting the time, the roadway 21 can slip relative to the center mobile 17.

[0046] The upper end of the barrel pinion body 22 protrudes above the hour wheel 24 and is arranged below an upper end of the axis of the fourth mobile 20. The minute hand 7 is fixed to the upper end of the barrel pinion body 22. Consequently, the minute hand 7 is located closer to the dial 4 than the second hand 8 fixed to the fourth mobile 20. Consequently, the minute hand 7 can move directly due to a rotation of the barrel pinion 21. Minute hand 7 rotates at a rotational speed adjusted by the escapement and the speed regulator, i.e. , rotates once every 60 minutes.

The hour wheel 24 constituting the timer is arranged coaxially with respect to the central axis C at the bottom of the plate 11, and rotates around the central axis C. The hour wheel 24 includes a body of cylindrical hour wheel 25 which surmounts the barrel pinion body 22 and an hour gear wheel set 26 which is integrally formed at a lower end of the hour wheel body 25, and meshes with a minute wheel pinion .

The minute wheel (not shown) is pivotally mounted between a rear support plate 16 and the plate 11, and the rear support plate 16 is arranged between the dial 4 and the plate 11. The minute wheel includes the minute wheel pinion meshing with the hour gear wheel set 26 and a minute wheel gear wheel set meshing with the roadway 21. Therefore, the minute wheel meshes with the roadway 21 and the hour wheel 24.

Consequently, the hour wheel 24 rotates around the central axis C together with the rotation of the floor 21 and the minute wheel. An upper end of the hour wheel body 25 protrudes above the dial 4 and is disposed below the upper end of the barrel pinion body 22. The hour hand 6 is attached to the upper end of the wheel body from hours 25.

[0050] Consequently, the hour hand 6 is located closer to the dial 4 than the minute hand 7 fixed to the floor 21. Consequently, the hour hand 6 can move directly following the rotation of the hour wheel 24. The hour hand 6 rotates at a rotational speed adjusted by the escapement and the speed regulator, that is, rotates once every 12 hours.

The minute wheel is linked to the winding stem 15 in a state where the winding stem 15 shown in Figure 1 can be positioned at 2 different levels, as described below. Consequently, the minute wheel rotates continuously under the action of the rotation of the winding stem 15, in a state where the winding stem 15 can be in a 2-level position.

An intermediate 24 hour wheel 30 shown in Figures 2 and 3 meshes with the top hour wheel gear 26.

The intermediate 24 hour wheel 30 is mainly supported by the plate 11 so as to rotate around an axis M. The intermediate 24 hour wheel 30 represented in FIG. 24 hour 31 meshing with the hour wheel gear wheel 26 and an intermediate 24 hour pinion 32. As a result, the intermediate 24 hour wheel 30 rotates around the axis M together with the rotation of the hour wheel 24.

(24 hour wheel)

As illustrated in Figures 3 to 6, the 24-hour wheel 40 is arranged coaxially with respect to the central axis C and rotates around the central axis C.

The 24 hour wheel 40 includes a 24 hour pinion 41 which has a cylindrical shape and surmounts the hour wheel body 25, and a 24 hour gear wheel set 42 which is integrally formed with the pinion. 24 hour 41, and a 24 hour 43 wheel gear mobile that tops the 24 hour 41 pinion.

[0056] An upper end of the 24-hour pinion 41 protrudes above the dial 4 and is arranged below the upper end of the hour wheel body 25. The 24-hour hand 5 is fixed to the upper end of the 24 hour sprocket 41.

[0057] Consequently, the 24-hour hand 5 is located closer to the dial 4 than the hour hand 6. Consequently, the 24-hour hand 5 can move directly following the rotation of the wheel. 24 hours 40. The 24 hour hand 5 rotates at a rotational speed adjusted by the escapement and the speed regulator, that is, rotates once every 24 hours.

As shown in Fig. 6, at a lower end of the 24-hour pinion 41, an hour jumper pinion 45 having a plurality of teeth 45a projecting in a radial direction is arranged below the gear wheel set 24 hour gear 42. The plurality of teeth 45a are formed at equal intervals over an entire circumference of the 24 hour pinion 41. In the example shown, the number of teeth of the plurality of teeth 45a is 24.

As illustrated in Figures 5 and 6, the 24-hour gear mobile 42 is combined in one piece with the 24-hour pinion 41, for example by driving. As a result, the 24 hour pinion 41 and the 24 hour gear 42 always rotate around the central axis C in synchronization.

As shown in Fig. 6, the 24-hour gear wheel set 43 is disposed coaxially with the central axis C, and has an insertion hole 46 provided in a central part of the wheel set. 24 hour wheel gear 43 which is used for the insertion of the entire 24 hour pinion 41, including the hour jumper pinion 45. Accordingly, the 24 hour wheel gear mobile 43 is arranged in so as to overcome the hour jumper pinion 45, with the 24 hour pinion 41 inserted into the insertion hole 46.

[0061] The plurality of teeth 45a are in sliding contact with an inner peripheral surface of the insertion hole 46. Accordingly, the 24 hour pinion 41 and the 24 hour wheel gear wheel set 43 are mutually combined to each other such that the 24 hour pinion 41 and the 24 hour wheel gear 43 can rotate relative to each other about the central axis C, but cannot be moved relative to each other in the radial direction.

The 24 hour wheel gear set 43 further has an insertion hole 48 to accommodate an hour jumper 47 within it. Fixing hole 48 is shaped so that it can communicate with insertion hole 46.

The hour jumper 47 is elastically deformable in the radial direction, and has a cantilever shape, one base end 47a of which is connected to the inner peripheral surface of the insertion hole 46. The hour jumper 47 is disposed inside the fixing hole 48 and is located in the same plane as the plurality of teeth 45a of the hour jumper pinion 45.

The hour jumper 47 extends from the base end 47a along a circumferential direction of the 24-hour pinion 41, and has, at a free end corresponding to its movable tip, a control finger 47b which engages with the teeth 45a so as to be able to release from the outside in the radial direction. The control finger 47b is held in compression against the hour jumper pinion 45 by a restoring force resulting from the elastic deformation of the hour jumper 47, and engages with the jumper teeth 45a.

Accordingly, the 24-hour wheel gear mobile 43 is combined with the 24-hour pinion 41 in a state where the control finger 47b of the hour jumper 47 comes to engage with the teeth 45a. Accordingly, by engaging the control finger 47b with the teeth 45a of the hour jumper pinion 45, a rotational force of the 24 hour wheel gear wheel set 43 can be transmitted to the 24 hour pinion 41, and the 24-hour wheel gear wheel 43 and 24-hour pinion 41 co-rotate with each other.

As shown in Figures 5 and 6, the 24 hour wheel gear wheel 43 meshes with the 24 hour idler pinion 32. As a result, the 24 hour wheel 40 rotates due to rotation of the wheel. 24 hour wheel via the intermediate 24 hour wheel 30. In particular, the 24 hour wheel 40 is connected to the 24 hour wheel via the intermediate 24 hour wheel 30 so that a gear ratio, for example, is cut in half with respect to the hour wheel 24. Accordingly, as described above, the 24 hour wheel 40 and the 24 hour hand 5 can rotate once every 24 hours.

[0067] When a predetermined torque acts between the 24-hour pinion 41 and the 24-hour wheel gear mobile 43, the hour jumper 47 is elastically deformed so as to separate from the hour jumper pinion. 45, and the engagement of the control finger 47b with the teeth 45a is released. As a result, the 24 hour pinion 41 and the 24 hour wheel gear wheel set 43 can rotate relative to each other while the hour jumper 47 slips relative to the hour jumper pinion 45 .

[0068] However, the control finger 47b can come to engage with the teeth 45a so as to allow the 24 hour pinion 41 to rotate relative to the 24 hour wheel gear mobile 43 in one direction, and to block the rotation of the pinion 24 hours 41 in the other direction. Consequently, the hour jumper 47 can have a ratchet function which blocks the rotation only in one direction. In this case, the hour jumper 47 allows the 24 hour pinion 41 to rotate relative to the 24 hour wheel gear wheel 43 in the direction the 24 hour wheel 40 rotates due to normal motion of the needle. Accordingly, the 24-hour gear wheel 42 and the 24-hour pinion 41 can rotate, and the 24-hour hand 5 can be corrected independently of each other.

(Information indication mechanism)

As illustrated in Figures 2 and 3, the information indicating mechanism 12 is a mechanism indicating information other than the current time, and it includes the date indicator (first indicator wheel according to the invention) 50 indicating the date 9 as first information, the 24-hour wheel (the second indicator wheel according to the invention) 40 fixed to the 24-hour hand 5 indicating a second time zone as second information, and the indicator correction mechanism 13 correcting the date indicator 50 and the 24-hour wheel 40.

[0070] Therefore, the 24-hour wheel 40 described above constitutes the timer for the timepiece 1 and also functions as the information indicating mechanism 12 according to the present embodiment.

The date indicator 50 is an annular element rotatably arranged on an upper surface of the plate 11, and clearly indicates in order the date 9 (date information) representing the first to the 31 <th> days. in the circumferential direction. The date clear indication method 9 includes, for example, printing, engraving, and sticker attachment, but is not particularly limited.

In each of the figures other than Figure 2, date 9 may not be shown.

The date indicator 50 rotates clockwise, as shown by the arrow K shown in Figure 2 when viewed from above (dial side 4). Therefore, the advancement of the day during a date change can be effected by rotating the date indicator 50 clockwise.

[0074] However, the direction of rotation of the date indicator 50 is not limited to the above case, and for example, the date indicator 50 could be configured to rotate counter-clockwise. watch to make the progress of the day.

[0075] A plurality of inner teeth 51 are formed on an inner peripheral edge of the date indicator 50 at equal intervals along the circumferential direction around the entire circumference. The number of internal teeth 51 is, for example, 31. Consequently, by rotating the date indicator 50 by only one tooth among the internal teeth 51, the date 9 to be indicated through the date window 4a can only be brought forward by one day.

[0076] However, the number of the internal teeth 51 is not limited to 31, and could be suitably adjusted to, for example, 62. In this case, the rotation level of the date indicator 50 to correspond to an amplitude equivalent to one calendar day can be appropriately adjusted according to the number of internal teeth 51.

[0077] The date indicator 50 configured as described above is linked to the hour wheel 24 via a date drive train (not shown), which turns when the hour wheel 24 turns. In other words, when the hour wheel 24 rotates once every 12 hours, the date indicator 50 rotates only one tooth per day (24 hours), and rotates around the central axis C in 31 days. A position of rotation of the date indicator 50 is regulated by a date jumper (regulating element) (not shown), and can rotate by only one tooth to advance the date 9 by only one day.

(Indicator correction mechanism)

The indicator correction mechanism 13 is arranged between the date indicator 50 and the 24-hour wheel 40.

[0079] The indicator correction mechanism 13 can pivot about a pivot axis N, and includes a tilting lever 60 which moves between a standby position P0 shown in Figures 2 and 3, a first position of correction P1 shown in Figure 7, and a second correction position P2 shown in Figure 8, a calendar correction wheel (the first correction wheel according to the invention) 70 which approaches the date indicator 50 via the tilting lever 60 and meshes with the internal teeth 51 of the date indicator 50, a 24-hour correction wheel (the second correction wheel according to the invention) 80 which approaches the 24-hour wheel 40 via the tilting lever 60 and meshes with the 24-hour gear wheel set 42, and a setting transmission wheel 90 which transmits the energy transmitted from the outside to the calendar correction wheel 70 and the 24 hour correction 80.

[0080] The calendar correction wheel 70 rotates around a first axis of rotation O1 which is non-coaxial with the pivot axis N, is arranged so as to approach or separate from the date indicator 50, and can approach the date indicator 50 via the tilt lever 60 to mesh with the internal teeth 51 of the date indicator 50 when the tilt lever 60 is moved to the first correction position P1 as shown in Figure 7.

[0081] The 24-hour correction wheel 80 rotates around a second axis of rotation O2 which is non-coaxial neither with the pivot axis N nor with the first axis of rotation O1, is arranged so as to approach or separate from the 24 hour gear wheel set 42, and can approach the 24 hour gear wheel set 42 via the toggle lever 60 to mesh with the 24 hour gear wheel set 42 when the lever tilting 60 is moved into the second correction position P2, as shown in Figure 8.

[0082] When the tilting lever 60 is located in the standby position P0 and in the second correction position P2, the calendar correction wheel 70 separates from the date indicator 50 and does not mesh with the teeth. 51. When the tilting lever 60 is located in the standby position P0 and at the first correction position P1, the 24 hour correction wheel 80 separates from the 24 hour gear mobile 42 does not mesh with the 24 hour gear mobile 42.

As illustrated in Figures 2 and 3, the standby position P0 is a position where the calendar correction wheel 70 and the 24 hour correction wheel 80 separate from the date indicator 50 and the gear 24 hours 42.

[0084] The adjustment transmission wheel 90 rotates around the pivot axis N and is arranged in a state where it meshes with the calendar correction wheel 70 and the 24-hour correction wheel 80, and plays a in the transmission of the energy transmitted from the outside to the calendar correction wheel 70 and the 24 hour correction wheel 80.

As illustrated in Figures 9 and 10, adjustment transmission wheel 90 includes a first adjustment transmission wheel 91 disposed below tilt lever 60, and a second adjustment transmission wheel 92, disposed at the above the tilting lever 60, and which is integrally integral with the first adjustment transmission wheel 91.

[0086] In the following, the indicator correction mechanism 13 will be described in detail.

As shown in Figures 11 and 12, the tilt lever 60 is disposed above the rear support plate 16 and has a thin plate shape. The tilt lever 60 includes a tilt lever body 61 having an inner end 61a located on the 24 hour wheel 40 side, and an outer end 61b located on the date indicator 50 side, and a lever spring 62 integrally formed with the tilting lever body 61.

[0088] The outer end 61b of the tilt lever body 61 has a first connection hole 63 for mounting the calendar correction wheel 70. A first fixing pin 64 is fixed to the first connection hole 63 by driving or similar. The calendar correction wheel 70 is rotatably connected to the first fixing pin 64 in a state where it overlaps on an upper surface of the tilt lever body 61. Accordingly, the calendar correction wheel 70 can rotate around of the first axis of rotation O1 in a state where it cannot be dismantled thanks to the first fixing pin 64.

[0089] Therefore, according to the present embodiment, the calendar correction wheel 70 is assembled with the tilt lever 60 by being rotatably mounted thereon.

[0090] The inner end 61a of the tilting lever body 61 has a second connecting hole 65 for mounting the 24-hour correction wheel 80. A second fixing pin 66 is fixed to the second connecting hole 65 by hunting or the like. The 24 hour correction wheel 80 is rotatably connected to the second fixing pin 66 in a state where it overlaps the upper surface of the tilt lever body 61. Accordingly, the 24 hour correction wheel 80 rotates around of the second axis of rotation O2 in a state where it cannot be disassembled thanks to the second fixing pin 66.

[0091] Therefore, according to the present embodiment, the 24-hour correction wheel 80 is assembled with the tilt lever 60 and is rotatably mounted thereon.

The lever spring 62 has a cantilever shape cantilevered toward the inner end 61a of the tilt lever body 61. The lever spring 62 has a base end connected to the inner end 61 a of the tilt lever body 61, and extends from a base end to a free „tip“ end. The lever spring 62 is elastically deformable, and is arranged such that its free end always tends to come closer to the tilting lever body 61 under the action of the elastic return force following deformation.

[0093] The tilt lever 60 configured as described above is attached to a connecting shaft 93 so as to sandwich (pinch) between the tilt lever body 61 and the free end of the lever spring 62 , the connecting shaft 93 constituting the adjustment transmission wheel 90. A central axis of the connecting shaft 93 is the pivot axis N.

[0094] Therefore, in the present embodiment, the tilting lever 60 and the adjustment transmission wheel 90 are combined in a state where there is a predetermined rotational resistance. Accordingly, the tilting lever 60 can rotate about the pivot axis N under the action of the rotation of the adjustment transmission wheel 90 as long as the tilting lever 60 does not experience a resistance exceeding the resistance in spin. However, when the tilt lever 60 experiences resistance that exceeds the rotational resistance, the tilt lever 60 allows the adjustment transmission wheel 90 to rotate relative to the tilt lever 60.

The second securing pin 66 securing the 24 hour correction wheel 80 to the tilt lever 60 is formed to extend downward from the tilt lever 60, and as shown in Figures 11 and 13, is inserted into a guide groove 100 provided in the rear support plate 16. In Fig. 13, the tilting lever 60 and the 24 hour correction wheel 80 are not shown.

The guide groove 100 includes a main guide groove 101 formed to extend in a circumferential direction around the pivot axis N, and an auxiliary guide groove 102 formed to communicate with the main guide groove 101 and extend in a radial direction around the pivot axis N. In the illustrated example, the main guide groove 101 and the auxiliary guide groove 102 are connected to each other by such that the guide groove 100 has an L-shape in plan view. However, the invention is not limited to such a configuration, and the main guide groove 101 and the auxiliary guide groove 102 could be connected so that the guide groove 100 has a T shape in a plan view. , for example. In any case, the guide groove 100 is not limited to a specific shape.

[0097] The second fixing pin 66 moves in the main guide groove 101 when the tilting lever 60 pivots. As a result, the pivoting of the tilt lever 60 around the pivot axis N can be stabilized, and the 24-hour correction wheel 80 can be stabilized with less rattle.

[0098] When the tilting lever 60 is located in the first correction position P1, the second fixing pin 66 is brought into contact with a first peripheral end, to which the auxiliary guide groove 102 is connected, among the peripheral ends of the main guide groove 101. Accordingly, the tilting lever 60 is easily positioned in the first correction position P1. When the tilting lever 60 is located in the second correction position P2, the second fixing pin 66 is brought into contact with a second peripheral end located on the side of the 24-hour wheel 40, peripheral ends of the guide groove main 101. Accordingly, the tilt lever 60 is easily positioned in the second correction position P2.

[0099] The auxiliary guide groove 102 is an assembly portion for the insertion of the second fixing pin 66 when the tilting lever 60 is assembled so as to sandwich the connecting shaft 93 of the wheel adjustment transmission 90. However, when the tilting lever 60 is assembled, the auxiliary guide groove 102 can be omitted as long as the second fixing pin 66 can be inserted directly into the main guide groove 101. Therefore, the auxiliary guide groove 102 is not always necessary and may not be provided.

As illustrated in Figures 9 and 10, the adjustment transmission wheel 90 comprises the first adjustment transmission wheel 91 disposed below the tilting lever 60, and the second adjustment transmission wheel 92 disposed above above the tilting lever 60, and integrally secured in one piece with the first adjustment transmission wheel 91.

The first adjustment transmission wheel 91 is arranged below the tilt lever 60 and the rear support plate 16. The first adjustment transmission wheel 91 includes the connecting shaft 93 which is arranged coaxially with the pivot axis N and protrudes upwards. As described above, the tilting lever 60 is combined with the first adjustment transmission wheel 91 via the connecting shaft 93.

The second adjustment transmission wheel 92 is arranged above the tilting lever 60 and is fixed to the connecting shaft 93 by driving in or the like. Accordingly, the tilting lever 90 can rotate the first adjustment transmission wheel 91 and the second adjustment transmission wheel 92 together around the pivot axis N.

As shown in Figures 12 and 14, the adjustment transmission wheel 90 configured as described above is linked to the winding stem 15 via a correction gear train 110, rotates around the pivot axis N in a first direction L1 or a second direction L2 when the winding stem 15 rotates.

(winding stem)

[0104] As illustrated in Figures 12 and 14, winding stem 15 is rotatably inserted into a guide hole 11a provided in plate 11. Crown 14 shown in Figure 1 is connected to winding stem 15 Consequently, the winding stem 15 can be driven in rotation via the crown 14.

[0105] In a position corresponding to level 1 where the winding stem 15 is pulled out by one notch relative to a level 0 in, for example, the winding stem 15 and a first transmission wheel 111 can be connected the to each other, and the first transmission wheel 111 rotates in synchronization with the rotation of the winding stem 15.

[0106] In a position corresponding to level 2 where the winding stem 15 is pulled out two notches, the winding stem 15 can be connected to the minute wheel via, for example, a sliding pinion (not shown), and the time can be corrected.

(Correction gear)

[0107] As illustrated in FIGS. 12 and 14, the correction gear train 110 comprises the first transmission wheel 111 connected to the winding stem 15 when the winding stem 15 is positioned in the level 1 position, a second transmission wheel transmission 112 rotating following the rotation of the first transmission wheel 111, a third transmission wheel 113 rotating following the rotation of the second transmission wheel 112, a fourth transmission wheel 114 rotating following the rotation of the third transmission wheel transmission 113, a fifth transmission wheel 115 rotating following the rotation of the fourth transmission wheel 114, and a sixth transmission wheel 116 disposed coaxially with the fifth transmission wheel 115 and rotating synchronously with the fifth transmission wheel. transmission 115.

The second transmission wheel 112, the third transmission wheel 113, the fourth transmission wheel 114, the fifth transmission wheel 115, and the sixth transmission wheel 116 are mainly arranged on the upper face of the plate 11, and are each individually rotatably mounted thereon. The sixth transmission wheel 116 is disposed above the fifth transmission wheel 115 and meshes with the first setting transmission wheel 91.

[0109] Consequently, by rotating the winding stem 15 in a positioning state corresponding to the level 1 position, energy (rotary torque) can be transmitted to the adjustment transmission wheel 90 via the correction gear train 110 , and the adjustment transmission wheel 90 rotates around the pivot axis N.

[0110] In the present embodiment, by rotating the winding stem 15 in a first direction of operation F1 represented in FIG. 12, the adjustment transmission wheel 90 can rotate in the first direction L1, so that the tilting lever 60 can pivot in the direction of the first correction position P1. Conversely, by rotating winding stem 15 in a second direction of operation F2 shown in FIG. 12, adjustment transmission wheel 90 can rotate in second direction L2, so that tilting lever 60 can pivot towards the second correction position P2.

(Functioning of the timepiece)

In what follows, the operation of a timepiece 1 having a configuration as mentioned above will be described.

[0112] According to the timepiece 1 of the embodiment described herein, under the impetus of the energy of the mainspring and regularly driving the front wheel train and the timer in rotation via the escapement and the speed regulator, the center mobile 17 and the third mobile rotate, and the fourth mobile 20 rotates once every 60 seconds. As a result, the seconds hand 8 can rotate once every 60 seconds. At the same time, the roadway 21 turns once every 60 minutes, and the hour wheel 24, for example, turns once every 12 hours, and therefore the minute hand 7 can turn once every 60 minutes and the 6 hour hand can turn once every 12 hours. Since the 24-hour wheel 40 turns once every 24 hours, the 24-hour hand 5 can turn once every 24 hours.

[0113] Accordingly, the time can be indicated appropriately, and the second time zone can be indicated appropriately by using the 24-hour hand 5.

[0114] Since the date indicator 50 can rotate via the date drive cog when the hour wheel 24 turns, for example, when reaching midnight, the date indicator 50 can rotate only one tooth. by exerting a force against the date jumper. Consequently, the date 9 can be advanced by one day, and the date can be indicated in an appropriate manner.

[0115] In this way, the information indicating mechanism 12 includes the date indicator 50 and the 24-hour wheel 40, and therefore in addition to the indication of the hour, the information of the second time zone time and date information can be indicated at the same time, and a multifunctional timepiece 1 in indications can be obtained.

[0116] Next, a case where the date indicator 50 and the 24-hour wheel 40 are corrected will be described.

[0117] In this case, the crown 14 is extended by one notch, and the winding stem 15 is moved from the level 0 position to the level 1 position. Consequently, the winding stem 15 and the first wheel transmission wheels 111 can be connected to each other, and the first transmission wheel 111 can be rotated in synchronization with the rotation of the winding stem 15. Therefore, as shown in Fig. 12 , by rotating the winding stem 15, power can be transmitted to the adjustment transmission wheel 90 via the correction gear train 110, and the adjustment transmission wheel 90 can rotate around the pivot axis N.

[0118] The adjustment transmission wheel 90 and the tilting lever 60 are combined with each other with a predetermined rotational resistance, and therefore by rotating the adjustment transmission wheel 90, the tilting lever 60 can pivot around the pivot axis N following the rotation of the adjustment transmission wheel 90, and can be moved towards the first correction position P1 or the second correction position P2.

[0119] For example, by rotating the winding stem 15 in the first direction of operation F1 represented in FIG. 12, the adjustment transmission wheel 90 can rotate in the first direction L1, so that the tilting lever 60 can rotate from the standby position P0 shown in Figure 2 to the first correction position P1 shown in Figure 7. Accordingly, the calendar correction wheel 70 can approach the date indicator 50 and can mesh with the internal teeth 51 of the date indicator 50.

The calendar correction wheel 70 separates from the date indicator 50 until the tilting lever 60 passes from the standby position P0 to the first correction position P1, and therefore the correction wheel of the calendar 70 moves while rotating with the rotation of the adjustment transmission wheel 90 without meshing with the internal teeth 51 of the date indicator 50.

The calendar correction wheel 70 meshes with the internal teeth 51 of the date indicator 50, so that the calendar correction wheel 70 can transmit the energy transmitted from the adjustment transmission wheel 90 to the date indicator 50 and can rotate the date indicator 50. Accordingly, the indication of the date indicator 50 can be corrected and the date can be corrected.

When the tilting lever 60 arrives in the first correction position P1, the tilting lever 60 is positioned in the first correction position P1. Specifically, when the tilting lever 60 is located in the first correction position P1, the second fixing pin 66 on the side of the 24-hour correction wheel 80 comes into contact with the first peripheral end, towards which the groove auxiliary guide 102 is connected, among the peripheral ends of the main guide groove 101. Accordingly, the tilting lever 60 is positioned in the first correction position P1. Therefore, when the tilting lever 60 arrives in the first correction position P1, the continuation of the pivoting movement is prevented. Therefore, the tilting lever 60 receives the resistance exceeding the rotational resistance, and only the adjustment transmission wheel 90 can rotate while keeping the position of the tilting lever 60 as it is. Accordingly, the indication of the date indicator 50 can be corrected appropriately.

[0123] On the other hand, by rotating winding stem 15, for example, in the second direction of operation F2 shown in FIG. 12, adjustment transmission wheel 90 can rotate in the second direction L2, so that that the tilting lever 60 can pivot from the standby position P0 shown in Figure 2 to the second correction position P2 shown in Figure 8. Consequently, the 24-hour correction wheel 80 can approach the mobile d 24 hour gear 42, and mesh with the 24 hour gear mobile 42.

[0124] The 24 hour correction wheel 80 separates from the 24 hour gear mobile 42 until the tilting lever 60 arrives in the second correction position P2, and thus the 24 hour correction wheel 80 moves while rotating with the rotation of the adjustment transmission wheel 90 without meshing with the 24-hour gear mobile 42.

The 24 hour correction wheel 80 meshes with the 24 hour gear wheel 42, so that the 24 hour correction wheel 80 can transmit the energy transmitted from the adjustment transmission wheel 90 to the 24-hour gear wheel 42, and can rotate the 24-hour gear wheel 42. Accordingly, the indication of the 24-hour gear wheel 42 can be corrected, and the 24-hour hand 5 can be corrected.

When the tilting lever 60 arrives in the second correction position P2, the tilting lever 60 is positioned in the second correction position P2. Specifically, when the tilting lever 60 is located in the second correction position P2, the second fixing pin 66 on the side of the 24-hour correction wheel 80 comes into contact with the second peripheral end located on the side of the 24-hour wheel 40, among the peripheral ends of the main guide groove 101. Accordingly, the tilting lever 60 is positioned in the second correction position P2. Therefore, when the tilting lever 60 arrives at the second correction position P2, the continuation of the pivoting movement becomes impossible. Therefore, the tilting lever 60 experiences a resistance exceeding the rotational resistance, and only the adjustment transmission wheel 90 can rotate while keeping the position of the tilting lever 60 as it is. Accordingly, the indication of the 24-hour hand 5 can be corrected appropriately.

[0127] By rotating the tilt lever 60 in this way, the two correction wheels having different axes of rotation, i.e., the calendar correction wheel 70 and the 24-hour correction wheel 80 can move together with each other, and can mesh directly with the date indicator 50 or the 24-hour gear wheel set 42 to individually correct the indication. Therefore, it is not necessary to correct the indication of the date indicator 50 or the 24-hour gear wheel set 42 via the intermediate wheel or the like as done in the prior art, and the number of components can be reduced. Therefore, the flag correcting mechanism 13 can be realized more simply and can be produced at low cost.

[0128] The tilting lever 60 can pivot using the adjustment transmission wheel 90 to which the energy is transmitted by the winding stem 15; moreover, since the adjustment transmission wheel 90 meshes with the calendar correction wheel 70 and the 24-hour correction wheel 80, power can be directly transmitted from the adjustment transmission wheel 90 to the correction wheel calendar wheel 70 and the 24-hour correction wheel 80. Therefore, the number of components can be effectively reduced in this area as well.

[0129] As described above, since it is not necessary to correct the date indicator 50 or the 24-hour gear wheel set 42 via the intermediate wheel or the like, it is not necessary to release a space for arranging such an intermediate wheel or the like. Therefore, the size and the thickness can be reduced easily.

[0130] The calendar correction wheel 70 and the 24 hour correction wheel 80 can mesh with the date indicator 50 and the 24 hour gear 42, and therefore the calendar correction wheel 70 and the 24 hour correction 80 can be easily achieved. That is, since the calendar correction wheel 70 has a shape for meshing only with the setting transmission wheel 90 and the date indicator 50, the number of meshing parts can be only of two, and a tooth profile or the like be made easily and freely. Similarly, since the 24-hour correction wheel 80 is shaped to allow meshing with only the adjustment transmission wheel 90 and the 24-hour gear 42, the number of meshing portions can be two. , and the tooth profile or the like can be made easily and freely. Therefore, it is possible to improve the degree of freedom in the design of the calendar correction wheel 70 and the 24-hour correction wheel 80.

[0131] As described above, according to the indicator correction mechanism 13 of the present embodiment, the indications of the date indicator 50 and the 24-hour gear wheel set 42 (24-hour wheel 40) can be corrected appropriately while reducing the number of components, and the size and thickness can be reduced.

[0132] Since the information indicating mechanism 12 includes the indicator correction mechanism 13 described above, if necessary, the indications of the date indicator 50 and the 24-hour gear wheel set 42 ( 24-hour wheel 40) can be corrected appropriately, the date 9 can be indicated appropriately, and the second time zone can be indicated appropriately using the 24-hour hand 5. Therefore, for example, the dates, times, or the like of two countries (cities) which vary according to different time zones can be indicated appropriately individually.

Consequently, it is possible to produce a movement 10 and a timepiece 1 of reduced size and thickness, and which have high quality and high performance.

[0134] According to the present embodiment, by rotating the winding stem 15, the indication of the date indicator 50 or the 24-hour gear 42 (24-hour wheel 40) can be corrected separately while being freely selected, and thus the correction work can be easily realized and used.

[0135] Since the tilt lever 60 is combined with the calendar correction wheel 70, the calendar correction wheel 70 can move when the tilt lever 60 rotates. Therefore, the calendar correction wheel 70 can appropriately approach and separate from the date indicator 50 in response to the pivoting of the tilt lever 60. Therefore, when the tilt lever 60 is positioned in the first correction position P1, the calendar correction wheel 70 can appropriately mesh with the internal teeth 51 of the date indicator 50. reliable.

Similarly, when the tilt lever 60 is combined with the 24 hour correction wheel 80, the 24 hour correction wheel 80 can move when the tilt lever 60 rotates. Therefore, the 24 hour correction wheel 80 can appropriately approach and separate from the 24 hour gear wheel set 42 in response to the pivoting of the tilt lever 60. Therefore, when the tilt lever 60 is positioned in the second correction position P2, the 24 hour correction wheel 80 can properly mesh with the 24 hour gear wheel set 42. Thus, the indication of the 24 hour hand 5 can be corrected easily and reliably.

[0137] Since the tilt lever 60 can be integrally combined with the calendar correction wheel 70 and the 24-hour correction wheel 80, the indicator correction mechanism 13 can be assembled easily and efficiently.

When correcting the time, crown 14 is pulled back two notches and winding stem 15 is shifted from the position corresponding to level 0 to the position corresponding to level 2. Consequently, the minute wheel can be linked via, for example, the sliding pinion (not shown), and by rotating the winding stem 15, time corrections of the minute hand 7, of the hour hand 6, and of the 24 hour hand 5 can be made individually and the date indicator 50 can be corrected.

(Second Embodiment)

Hereinafter, a second embodiment according to the invention will be described with reference to the drawings. In this second embodiment, the same elements as those of the first embodiment are denoted by the same reference numerals, and they will not be illustrated again.

As shown in Figs. 15 and 16, in the indicator correction mechanism 130 according to this present embodiment, the calendar correction wheel 70 is arranged separately from the tilt lever 60, and is disposed between the platen 11 and rear support plate 16.

[0141] The calendar correction wheel 70 includes an upward and downward extending shaft 71. A lower end of this shaft 71 is inserted into a lower guide groove (referred to as a guide groove according to the invention) 131 arranged in the plate 11 and which shown in FIG. 17, and as illustrated in FIGS. 15 and 16, a upper end is inserted into an upper guide groove (also called guide groove according to the invention) 132 provided in the rear support plate 16.

[0142] The lower guide groove 131 and the upper guide groove 132 are arranged to face each other in a vertical direction, and are configured as an arc extending in a circumferential direction. around the pivot axis N according to a plan view. Accordingly, the calendar correction wheel 70 is movably guided along the lower guide groove 131 and the upper guide groove 132 so as to be able to approach and separate from the date indicator 50 .

As shown in Figs. 15 and 16, in the tilt lever 60 according to the present embodiment, the tilt lever body 61 comes into contact with the upper end of the shaft 71 of the correction wheel calendar 70 from an opposite side to date indicator 50 with shaft 71 interposed therebetween. Consequently, the tilting lever 60 can compress the calendar correction wheel 70 so as to bring it closer to the date indicator 50 while pivoting in the direction of the first correction position P1. Therefore, as shown in Figure 18, when the tilt lever 60 is moved to the first correction position P1, the calendar correction wheel 70 can mesh with the internal teeth 51 of the date indicator 50.

[0144] In this case, the shaft 71 of the calendar correction wheel 70 is positioned appropriately, for example, by coming into contact with peripheral ends of the lower guide groove 131 and the upper guide groove 132.

In the present embodiment, the calendar correction wheel 70 is disposed below the rear support plate 16, and therefore, as illustrated in Figure 16, the first adjustment transmission wheel 91 constituting the adjustment transmission wheel 90 meshes with the calendar correction wheel 70. Therefore, power can be directly transmitted to the calendar correction wheel 70 by the first adjustment transmission wheel 91, and the energy can be transmitted directly to the 24-hour correction wheel 80 by the second adjustment transmission wheel 92.

[0146] Also in the timepiece 1 according to the present embodiment including the indicator correction mechanism 130 configured in this way, as shown in Fig. 18, when the tilting lever 60 is moved to the first position of correction P1, the calendar correction wheel 70 can mesh with the internal teeth 51 of the date indicator 50, and thus the indication of the date indicator 50 can be corrected appropriately. Therefore, also in the case of the present embodiment, the same effects as those of the first embodiment can be obtained.

Also in the case of this embodiment, the tilting lever 60 can be positioned in the first correction position P1 and in the second correction position P2.

[0148] Specifically, when the tilt lever 60 is moved to the first correction position P1, the shaft 71 of the calendar correction wheel 70 comes into contact with at least one of the first end peripheral end located on the side of the date indicator 50, peripheral ends of the lower guide groove 131 and a first peripheral end located on the side of the date indicator 50, and peripheral ends of the upper guide groove 132. Thus, the tilting lever 60 can be positioned as far as the first correction position P1, before the continuation of the pivoting movement is made impossible.

[0149] When the tilting lever 60 is moved into the second correction position P2, similar to the first embodiment, the second fixing pin 66 on the side of the 24-hour correction wheel 80 comes into contact with the second end peripheral, located on the side of the 24-hour wheel 40, among the peripheral end portions of the main guide groove 101. Accordingly, the tilting lever 60 can be positioned in the second correction position P2, and the pursuit movement made impossible afterwards.

[0150] In the present embodiment, as shown in Fig. 19, when the tilting lever 60 rotates to reach the second correction position P2, the tilting lever 60 and the calendar correction wheel 70 cannot enter in mutual contact. However, also in this case, when the tilting lever 60 pivots to again reach the first correction position P1, the calendar correction wheel 70 can appropriately mesh with the internal teeth 51 of the date indicator 50.

(Variation of the second embodiment)

[0151] In the above second embodiment, for example, as shown in Figs. 20 and 21, an insertion hole 140 through which the shaft 71 of the calendar correction wheel 70 is inserted may be arranged in the tilt lever body 61.

[0152] By doing this, as shown in Figure 20, when the tilting lever 60 pivots to the first correction position P1, the tilting lever 60 can use an inner edge of the insertion hole 140 to compress the wheel. calendar correction 70 so as to approach the date indicator 50. As shown in Fig. 21, when the tilting lever 60 pivots to the second correction position P2, the tilting lever 60 can use the inner edge of the insertion hole 140 to compress the calendar correction wheel 70 so as to separate it from the date indicator 50.

[0153] Therefore, regardless of whether the tilt lever 60 is pivoted toward the first correction position P1 or the second correction position P2, the calendar correction wheel 70 can be compressed using the insertion 140, and thus the calendar correction wheel 70 can reliably approach and mesh with the date indicator 50, or can reliably separate from the date indicator 50 to release the gear relationship .

Also in this configuration, the tilting lever 60 can be positioned in the first correction position P1 and in the second correction position P2.

[0155] Specifically, when the tilting lever 60 is moved into the first correction position P1, the shaft 71 of the calendar correction wheel 70 comes into contact with at least one of the ends chosen from the first peripheral end located on the date indicator 50 side, peripheral ends of the lower guide groove 131, and the first peripheral end located on the date indicator 50 side, peripheral ends of the upper guide groove 132 , and the shaft 71 is sandwiched between the first peripheral end and the inner edge of the insertion hole 140. Consequently, the tilting lever 60 can be positioned in the first correction position P1, while at the same time making any continuation of the pivoting movement.

When the tilting lever 60 is moved into the second correction position P2, the shaft 71 of the calendar correction wheel 70 comes into contact with at least one of the ends chosen from among a second peripheral end located on the side of the 24 hour wheel 40, peripheral ends of the lower guide groove 131 and a second peripheral end located on the side of the 24 hour wheel 40, peripheral ends of the upper guide groove 132, and the shaft 71 is sandwiched between the second peripheral end and the inner edge of the insertion hole 140. Accordingly, the tilting lever 60 can be positioned in the second correction position P2, while at the same time making any continuation of the pivoting movement impossible. .

The embodiments of the invention are described above, are given by way of example only, but are not intended to limit the scope of the invention. In fact, other embodiments can come in a variety of other forms; moreover, various omissions, substitutions and changes in the form of the embodiments can be made without departing from the spirit of the invention. Embodiments and their modification include, for example, those which could have been easily devised by one skilled in the art, those which are substantially the same, and those which are within an equivalent range.

[0158] For example, in the embodiments above, the mechanical timepiece is described by way of example, but the invention is not limited to such a case, and can be applied to, for example , a quartz timepiece. In this case, for example, a driving force from a stepper motor can be used to turn each wheel.

In each of the above embodiments, the date indicator is adopted as the first indicator wheel for indicating the first information, and the 24-hour wheel having the 24-hour hand is adopted as the first indicator wheel. constituting a second indicator wheel to indicate the second information, but the invention is not limited to such a case. For example, a day indicator intended to indicate a day of the week could be employed as the first indicator wheel, or various indicator wheels indicating other information could be applied to the first indicator wheel and the second indicator wheel.

[0160] In each of the above embodiments, an exemplary case is described where, in order to sandwich (pinch), between the rocker lever body and the free end of the lever spring , the connecting shaft constituting the adjustment transmission wheel, by fixing the tilting lever, the tilting lever and the adjustment transmission wheel are combined in a state where a predetermined mutual rotational resistance is exerted, but the invention is not limited to such a configuration.

[0161] For example, by attaching the tilt lever to the calendar correction wheel so as to pinch the calendar correction wheel, and by attaching the tilt lever to the 24-hour correction wheel so as to pinch the 24-hour correction wheel, the tilting lever could be combined with the calendar correction wheel and the 24-hour correction wheel in the state having the predetermined rotational resistance. Even in this case, the tilting lever can pivot about the axis of rotation under the action of the rotation of the adjustment transmission wheel as long as the tilting lever does not experience a resistance exceeding the rotational resistance ci above, and when the tilting lever experiences resistance exceeding the rotational resistance above, the calendar correction wheel and the 24-hour correction wheel can rotate with the rotation of the adjustment transmission wheel while keeping the tilt lever position as it is.

[0162] Therefore, also in this case, the same operations and effects can be exerted.
