Technical field

The present invention relates to indication mechanism, movement and clock and watch.

Background technology

All the time, as the indication mechanism of the large date mode of the what is called that the date etc. is shown larger, these two date wheel are combined and carry out showing from " 01 " day to the date of " 31 " day by known such structure: the 1st date wheel and the 2nd date wheel on ten dates of display that possess display position date.

At this, the indication mechanism of the so large date mode in the past shown in following patent documentation 1 is described.

In the 1st date wheel, be circumferentially labeled with the numeral corresponding to the individual position of " 31 " day with " 01 " day.1st date wheel rotates according to scale (amount of 1 day) unit along with the rotation of revolving the date finger driving wheel turned around on the 1st.

On the other hand, in the 2nd date wheel, be circumferentially labeled with " 01 " day to ten of " 31 " day corresponding numerals (such as, " 0 " ~ " 3 ").The opportunity that 2nd date wheel is " 0 " from " 9 " transition in the 1st date wheel (individual position) rotates according to scale (amounts of 10 days) unit, further, rotate backward rapidly during " 01 " day and return initial position (such as " 0 ") (so-called inverse chaser structure) switching to date from " 31 " day.

Above-mentioned inverse chaser structure possesses: cam part, and it is equipped in the 1st date wheel, rotates integratedly with the 1st date wheel; Cam follower, it engages with this cam part; And actuating strut, it has the junction surface engaged with the 2nd date wheel.

Cam part has: cam surface, its diameter along with towards such as along sense of rotation a direction and expand; With migration portion, the maximum diameter of cam surface and most path couple together by it.

Actuating strut is configured to, can along with the rotation of cam part towards positive dirction swing, and along with this wobbling action make the 2nd date wheel rotate.Further, at cam follower in the migration portion of cam part during movement (during the most path movement of the maximum radial of cam surface), actuating strut swings in the opposite direction, makes the 2nd date wheel be back to initial position thus.

, because the precision of cam surface exists limit, therefore, corresponding to the skew of cam surface relative to appropriate position, the position of the circumference of the 2nd date wheel offsets, and accompanies therewith, produce the position skew on date, therefore, the visual outward appearance etc. reducing or destroy product may be made.

(the 1st date wheel)

1st date wheel 23 is mounted to can rotate and be formed as ring-type on the whole relative to base plate 21, at its edge of opening, to be circumferentially spaced apartly formed towards the outstanding multiple internal tooths (the 1st calendar value transmission gear) 31 of radially inner side.Further, in the following description, by the direction of the axle center C along the 1st date wheel 23 referred to as axis, the direction around axle center C is called circumference, the direction vertical with axle center C is called radial direction.In addition, the date corresponding to " 01 " day to " 31 " day is formed with 31 internal tooths 31.

The back side (being positioned at the face (dial plate 11 side) of the dorsal part of movement 10) of the 1st date wheel 23 constitutes the 1st date display part 32, the 1st date display part 32 is labeled with " 01 " day ~ " 31 " day date in the date corresponding with individual position.Specifically, be marked with in the 1st date display part 32 with " 01 " day ~ " 09 " day on this 9 dates of corresponding " 1 " ~ " 9 ", with " 10 " day ~ " 19 " day on this 10 dates of corresponding " 0 " ~ " 9 ", with " 20 " day ~ these 10 dates of " 0 " ~ " 9 " corresponding to " 29 " day and with " 30 " day ~ " 0 " and " 1 " these 2 dates corresponding to " 31 " day.

Fig. 3 is the vertical view observing the 1st date wheel 23 from positive side.

In addition, as shown in Figure 2 and Figure 3, the surface (face being positioned at positive side of movement 10) of the 1st date wheel 23 is formed with cam part 34.Cam part 34 has the different multiple cam surfaces (the 1st ~ 4th cam surface 34a ~ 34d) of distance (hreinafter referred to as radius) radially apart from the axle center C of the 1st date wheel 23 on the face being positioned at radial outside.In the example in figure 3, each cam surface 34a ~ 34d direction (C2 direction) contrary with the sense of rotation (C1 direction) of the 1st date wheel 23 is circumferentially formed successively, and is formed as becoming large successively according to the order radius of the 1st cam surface 34a ~ the 4th cam surface 34d.

Specifically, the 1st cam surface 34a is used for the date of regulation " 01 " ~ " 09 ", and is the most path in each cam surface 34a ~ 34d.The end in the C2 direction circumferentially on the 1st cam surface 34a is formed with inclination connecting portion 35a, and this inclination connecting portion 35a tilts towards radial outside along with towards C2 direction.

2nd cam surface 34b is used for the date of regulation " 10 " ~ " 19 ", to be connected to arrange via above-mentioned inclination connecting portion 35a with the 1st cam surface 34a.For the 2nd cam surface 34b, the central angle around axle center C is larger than the 1st cam surface 34a, and radius ratio the 1st cam surface 34a is large.In addition, the end in the C2 direction circumferentially on the 2nd cam surface 34b is formed with inclination connecting portion 35b, and this inclination connecting portion 35b tilts towards radial outside along with towards C2 direction.

3rd cam surface 34c is used for the date of regulation " 20 " ~ " 29 ", to be connected to arrange via above-mentioned inclination connecting portion 35b with the 2nd cam surface 34b.For the 3rd cam surface 34c, around the central angle of axle center C and the equal of the 2nd cam surface 34b, and radius ratio the 2nd cam surface 34b is large.In addition, the end in the C2 direction circumferentially on the 3rd cam surface 34c is formed with inclination connecting portion 35c, and this inclination connecting portion 35c tilts towards radial outside along with towards C2 direction.

4th cam surface 34d is used for the date of regulation " 30 ", " 31 ", and to be connected with the 3rd cam surface 34c via above-mentioned inclination connecting portion 35c and to arrange.For the 4th cam surface 34d, the central angle around axle center C is less than the 1st cam surface 34a, and is the maximum diameter in each cam surface 34a ~ 34d.Further, for each cam surface 34a ~ 34b, the radius in same cam surface 34a ~ 34b is fixed throughout the circumferential.

In addition, the end (final position) being positioned at C2 side circumferentially of the 4th cam surface 34d and the end (start position) being positioned at C1 side circumferentially of the 1st cam surface 34a link together via migration portion 36.Migration portion 36 extends to radially inner side from the 4th cam surface 34d towards the 1st cam surface 34a, and in order to carry out described laterly inverse jumping display, migration portion 36 drops to suddenly most path from maximum diameter.But as long as allow radial migration, the part in migration portion 36 or entirety also can not have face.

At this, part on the surface of the 1st date wheel 23, be positioned at radial outside than cam part 34, is formed with guiding wall (following mechanism) 37, this guiding wall 37 under the state spaced apart relative to cam part 34 around cam part 34.Guiding wall 37 is formed in the complete cycle of cam part 34, and the face being positioned at radially inner side copies each cam surface 34a ~ 34d, inclination connecting portion 35a ~ 35c and migration portion 36 to be formed.Thus, between cam part 34 and guiding wall 37, mark off cam path 38, this cam path 38 copy the shape in each cam surface 34a ~ 34d, inclination connecting portion 35a ~ 35c and migration portion 36 and different apart from the distance radially of axle center C.

(date finger driving wheel and date revise wheel)

As shown in Figure 2, date finger driving wheel 25 makes the 1st date wheel 23 within (specified time limit) on the 1st, rotate 1 circle (when when reaching the morning 0) and self rotating to carry out date feeding with the amount that the date with 1 day is corresponding, and is configured to rotate 1 circle based on being rotated in 24 times of not shown little hour wheel.Specifically, date finger driving wheel 25 has: that engages with little hour wheel (not shown) via power wheel 41 changes day gear 42; With the jumping day pawl 43 that can engage with the internal tooth 31 of the 1st date wheel 23.

Date finger driving wheel 25 is rotated (arrow A of Fig. 2) clockwise based on the rotation of little hour wheel, engages thus with the internal tooth 31 of the 1st date wheel 23, makes the 1st date wheel 23 rotate the amount of a tooth to C1 direction.

Date is revised wheel 26 and is supported in base plate 21 in the mode that can rotate, and the date corrected tooth 44 formed in its outer peripheral edges engages with the internal tooth 31 of the 1st date wheel 23.Further, such as, when extracting table hat 16 (with reference to Fig. 1) out 1 grade from the usual position (0 level position) of the contacts side surfaces with clock and watch housing 3, the date is revised wheel 26 and engages with arbor 17.Thus, the revolving force of arbor 17 is passed to date correction wheel 26, revises wheel 26 and the 1st date wheel 23 is rotated, carry out date aligning (calendar adjustment) thus via the date.

(the 1st date pogo stick)

1st date pogo stick 27 has: bar portion 45, and its base end part is supported in the back side of base plate 21 in the mode that can swing (D1, D2 direction) around axis of swing D; Pawl 46 and junction surface 47 are gone through in 1st jumping, and they are arranged at the terminal part in bar portion 45; And the 1st date pogo stick spring 48, it is jumped from the inner side and the 1st of radial direction and goes through pawl 46 and abut, and exerts a force towards D1 direction to bar portion 45.

1st jumps and goes through pawl 46 shape triangular in shape when overlooking, outstanding to radial outside from the terminal part in bar portion 45, and is configured to its terminal part and can be bonded between the internal tooth 31 of the 1st date wheel 23.Further, the 1st jumping is gone through pawl 46 and is bonded between the internal tooth 31 of the 1st date wheel 23, and thus, the 1st date pogo stick 27 limits the rotation (the 1st restriction state) of the 1st date wheel 23.On the other hand, when the 1st date wheel 23 rotates, the 1st date pogo stick 27 is removed the 1st and is jumped and go through the joint of the internal tooth 31 of pawl 46 and the 1st date wheel 23, allows the rotation of the 1st date wheel 23 (the 1st takeoff state (with reference to Fig. 6)) thus.

Junction surface 47 is formed as jumping relative to the 1st going through the column that pawl 46 is configured in radially inner side at the terminal part in bar portion 45, and can engage with the 2nd date pogo stick 28 described later.

(the 2nd date wheel)

Fig. 4 is the vertical view of the movement 10 that the state being equipped with the 2nd date wheel 24 (the 2nd date display part 52) is shown.

As shown in Figure 2, Figure 4 shows, the 2nd date wheel 24 has the 2nd date wheel gear 51 (with reference to Fig. 2) and is fixed on the 2nd date display part 52 (with reference to Fig. 4) on the 2nd date wheel gear 51.

First, as shown in Figure 4, the 2nd date display part 52 is that external diameter is formed as equal with the 1st date wheel 23 by riveting the discoideus parts being fixed in the dorsal part of the 2nd date wheel gear 51 such as fixing.Part on the 2nd date display part 52, that overlap with the 1st date display part 32 of the 1st date wheel 23 in the axial direction, be marked with " 01 " day ~ " 31 " day date in ten corresponding dates.Specifically, the 2nd date display part 52 is marked with expression " 01 " day ~ " 09 " day between ten " 0 " this word, expression " 10 " day ~ " 19 " day between ten " 1 " this word, expression " 20 " day ~ " 29 " day between " 2 " this word of ten and represent " 30 " day, " 3 " this word of ten between " 31 " day.In the example in the figures, the word of these " 0 " ~ " 3 " marks along C1 direction in the circumferential at spaced intervals successively.

In addition, the part on the 2nd date display part 52, to be positioned at each word right side, is formed with the window portion 53 can observing the 1st date display part 32 (date of individual position).Further, the window frame in window portion 53, except left border, is positioned at outside than the window frame of the date window 15 of above-mentioned dial plate 11, thus cannot be observed by date window 15 (with reference to Fig. 1).

In the example in fig. 4, the 2nd date display part 52 is formed as discoideus, but the part worked in fact on the 2nd date display part 52 is the angular range between dummy line 54a, 54b radially extended from axis.Therefore, the shape of the 2nd date display part 52 also can be with the plate of dummy line 54a, the 54b fan shape that is radius.In addition, in the example in the figures, the region of the lower-left on the 2nd date display part 52 is position beyond the position when date window 15 is configured in 12 (such as 3 time position), the selectable region that can be utilized in order to the word (" 0 " ~ " 3 ") of ten is attached to the part corresponding with the position of date window 15.

In addition, in the example in the figures, the above-mentioned selectable region on the 2nd date display part 52 is also formed with opening, but, as long as at least form fenestrate portion 53 in the part on the right side being positioned at each word.

As shown in Figure 2,2nd date wheel gear 51 be configured to coaxial discoideus with the axle center C of the 1st date wheel 23,2nd date wheel gear 51 to be configured in individual position from " 9 " to " 0 " mobile time (such as, during from " 09 " day to " 10 " day transition) or from " 31 " day to " 01 " day transition time rotate, thus, each word of the 2nd date display part 52 observed by date window 15 is switched.

In outer peripheral edges, the opposed diametrically part of the 2nd date wheel gear 51, the angular range respectively throughout regulation is formed with multiple claw 55 and teeth portion (the 2nd calendar value transmission gear) 56.

Claw 55 can engage with the 2nd date pogo stick 28, and gives prominence to towards radial outside, and claw 55 is formed with 3 with the word of the 2nd date display part 52 is spaced apart in the circumferential accordingly.

Teeth portion 56 is given prominence to towards radial outside, engages with the action gear portion 65 described later of actuating strut 29.Further, in the example in figure 2, claw 55 and teeth portion 56 are configured in circumferentially same in the outer peripheral edges of the 2nd date wheel gear 51, but, as long as be formed on the 2nd date wheel gear 51, also can not be configured in circumferentially same.

(actuating strut)

As shown in Figure 2, actuating strut 29 is formed as T-shaped when overlooking, and has: the bar main body 61 extended along a direction; With the arm 62,63 at two ends being respectively formed at bar main body 61.

The one end part of bar main body 61 is in the part overlapped with above-mentioned 1st date wheel 23 in the axial direction, and the other end of bar main body 61 is positioned at radially inner side than the 1st date wheel 23.Bar main body 61 using be located at the boundary member of arm 62 of an end as axis of swing E, be supported in base plate 21 in the mode that can swing (E1, E2).

The terminal part of the arm 62 (arm 62 an end of bar main body 61 is arranged) in each arm 62,63, is formed with the ridge 64 that side of supporting or opposing is outstanding.This ridge 64 plays function as the cam follower be bonded in the cam path 38 that marked off by above-mentioned cam part 34 and guiding wall 37.Further, along with the rotation of the 1st date wheel 23 (cam part 34), ridge 64 is along each cam surface 34a ~ 34d, inclination connecting portion 35a ~ 35c and migration portion 36 relative movement, and thus, actuating strut 29 swings around axis of swing E.

In the outer peripheral edges of another arm 63 (arm 63 arranged in the other end of bar main body 61), be formed with the action gear portion 65 of engaging with the teeth portion 56 of the 2nd above-mentioned date wheel gear 51.Therefore, the 2nd above-mentioned date wheel 24 is rotated around axle center C along with the wobbling action of actuating strut 29.

Further, " 01 " of each moon day ~ " 09 " day, actuating strut 29 is positioned at the end (the 1st state) of the E1 side around axis of swing E.In this case, the ridge 64 on actuating strut 29 is positioned on the 1st cam surface 34a of cam part 34, and action gear portion 65 engages with the end of the C1 side circumferentially in the teeth portion 56 of the 2nd date wheel gear 51.

In addition, " 10 " of each moon day ~ " 19 " day, actuating strut 29 becomes the 2nd state (with reference to Figure 10) moving a stage than the 1st above-mentioned state to E2 side.In this case, the ridge 64 on actuating strut 29 is positioned on the 2nd cam surface 34b of cam part 34, action gear portion 65 with in the teeth portion 56 of the 2nd date wheel gear 51, the part that moves a stage to C2 side than the 1st state engages.

" 20 " of each moon day ~ " 29 " day, actuating strut 29 becomes the 3rd state moving a stage than the 2nd state further to E2 side.In this case, the ridge 64 on actuating strut 29 is positioned on the 3rd cam surface 34c of cam part 34, action gear portion 65 with in the teeth portion 56 of the 2nd date wheel gear 51, the part that moves a stage to C2 side further than the 2nd state engages.

Further, in " 30 " day, " 31 " day of each moon, actuating strut 29 is positioned at the end (the 4th state: with reference to Figure 11) of the E2 side around axis of swing E.In this case, the ridge 64 on actuating strut 29 is positioned on the 4th cam surface 34d of cam part 34, and action gear portion 65 engages with the end of the C2 side circumferentially in the teeth portion 56 of the 2nd date wheel gear 51.

And, in the present embodiment, swing along the shape of cam part 34 by making actuating strut 29, constitute so so-called inverse chaser structure: after making the 2nd date wheel 24 (the 2nd date wheel gear 51) rotate from " 0 " towards " 3 " stage stage ground, turn to " 0 " from " 3 " rapidly.

(the 2nd date pogo stick)

2nd date pogo stick 28 is formed as L-shaped when overlooking, and with its sweep for axis of swing F, is supported in base plate 21 in the mode that can swing (F1, F2).Bar portion 72 on the 2nd date pogo stick 28, that extend to end side relative to sweep, is formed with the joint 73 that can engage with the junction surface 47 of the 1st above-mentioned date pogo stick 27.

In addition, the bar portion 74 extended to another side relative to sweep on the 2nd date pogo stick 28, be formed engage with the claw 55 of the 2nd above-mentioned date wheel gear 51 the 2nd jump and go through pawl 75.Further, the 2nd pogo stick spring 76 exerts a force to F1 direction to the 2nd date pogo stick 28.

Further, go through pawl 75 by making the 2nd jumping and engage with the claw 55 of the 2nd date wheel gear 51, the 2nd date pogo stick 28 limits the rotation (the 2nd restriction state) of the 2nd date wheel 24.On the other hand, 1st takeoff state and relieve 2nd jump the joint (2nd takeoff state) of going through pawl 75 and claw 55 above-mentioned along with the 1st date pogo stick 27 is changed to of the 2nd date pogo stick 28, allows the rotation of the 2nd date wheel gear 51 thus.That is, whenever the 1st date pogo stick 27 become the 1st takeoff state time (whenever carrying out the date feeding of 1 day), the 2nd date pogo stick 28 of present embodiment becomes the 2nd in linkage and to takeoff state.Therefore, when entering the beginning of the month from the end of month, (from when switching to " 01 " day " 31 " day) is also identical, and the 2nd date pogo stick 28 becomes the 2nd and to takeoff state.

(effect)

Next, the effect of above-mentioned clock and watch 1 is described.Further, in the following description, the elemental motion (switching action of standard date feed motion, the 2nd date wheel 24 and inverse work of beating) of indication mechanism 22 is described, then the date is described punctual action.

(elemental motion)

(standard date feed motion)

Fig. 5 ~ Fig. 7 is the key diagram of the action (standard date feed motion) for illustration of indication mechanism 22, and is the vertical view suitable with Fig. 2.Further, in the drawings, the numeral (" 0 " ~ " 3 ") of date window 15 and the 2nd date display part 52 is represented with dot-and-dash line.

First, under the state shown in fig. 5, in date window 15, " 01 " day is shown.That is, " 0 " of the 2nd date wheel 24 is positioned at the 2nd viewing area 15b of date window 15, and " 1 " of the 1st date wheel 23 is positioned at the 1st viewing area 15a of date window 15 (region in the window portion 53 (with reference to Fig. 4) in the 2nd date wheel 24).

In this case, each date pogo stick 27,28 becomes restriction state, limits the rotation of each date wheel 23,24 respectively.In addition, about actuating strut 29, under the 1st state, ridge 64 is positioned at the position by migration portion 36 on the 1st cam surface 34a, and action gear portion 65 engages with the end of the C1 side circumferentially in the teeth portion 56 of the 2nd date wheel gear 51.

Further, when date finger driving wheel 25 rotates based on the rotation of little hour wheel (not shown), the jumping day pawl of date finger driving wheel 25 43 engages with the internal tooth 31 of the 1st date wheel 23, makes the 1st date wheel 23 rotate the amount of a tooth towards C1 direction circumferentially.

As shown in Figure 6, when the 1st date wheel 23 starts to rotate, 1st date pogo stick 27 the 1st jump go through pawl 46 by the internal tooth 31 of the 1st date wheel 23 to overcome the 1st pogo stick spring 48 acting force direction on push away, thus, the 1st date pogo stick 27 swings to around the D2 direction of axis of swing D.Thus, the 1st date pogo stick 27 becomes the 1st and to takeoff state, and under the internal tooth 31 of the 1st date wheel 23 and the 1st of the 1st date pogo stick 27 jump the state going through pawl 46 sliding contact, the 1st date wheel 23 rotates.

When the 1st date pogo stick 27 swings to D2 direction, the junction surface 47 of the 1st date pogo stick 27 is engaged in the joint 73 of the 2nd date pogo stick 28, therefore, the 2nd date pogo stick 28 is pressed by the direction of the 1st date pogo stick 27 to the acting force overcoming the 2nd date pogo stick spring 76.Consequently, the 2nd date pogo stick 28 swings to around the F2 direction of axis of swing F, becomes the 2nd and jumps the joint of going through pawl 75 and claw 55 by the 2nd takeofing state of removing.Thus, the rotation of the 2nd date wheel 24 is allowed.

On the other hand, by making the 1st date wheel 23 rotate to C1 direction, thus, the ridge 64 of actuating strut 29 relatively moves to the direction away from migration portion 36 in cam path 38 along the 1st cam surface 34a.Now, on the 1st cam surface 34a, radius is equal throughout the circumferential, and therefore, the radial distance between ridge 64 and axle center C does not change.Therefore, actuating strut 29 does not swing, and accompanies therewith, the 2nd date wheel 24 (the 2nd date wheel gear 51) the also non rotating engaged with actuating strut 29.

Then, as shown in Figure 7, when the 1st jump go through pawl 46 cross an internal tooth 31 of the 1st date wheel 23 time, the 1st date pogo stick 27 swings to around the D1 direction of axis of swing D by means of the acting force of the 1st date pogo stick spring 48.Thus, the 1st date pogo stick 27 becomes the 1st restriction state again, the 1st jump go through pawl 46 be bonded on relative to the last time engage internal tooth 31 between rotate between the internal tooth 31 of the position of the amount of a tooth to C1 direction, restriction the 1st date wheel 23 rotation.

In addition, the 1st date pogo stick 27 returns the 1st restriction state, thus, removes the joint of the 1st date pogo stick 27 and the 2nd date pogo stick 28.Like this, the 2nd date pogo stick 28 swings to around the F1 direction of axis of swing F by means of the acting force of the 2nd date pogo stick spring 76.Thus, the 2nd date pogo stick 28 becomes the 2nd restriction state again, and the 2nd jumps and go through between claw 55 identical between pawl 75 is bonded on the last time engages claw 55, limits the rotation of the 2nd date wheel 24.

Like this, under the state that the 2nd date wheel 24 is static, the 1st date wheel 23 is made to rotate the amount of a tooth, thus, under the state that " 0 " of the 2nd date wheel 24 stops at the 2nd viewing area 15b in date window 15, in the 1st viewing area 15a, " 1 " of the 1st date wheel 23 switches to " 2 ".Thus, in date window 15, " 02 " day is shown.

And, " 01 " day ~ " 09 " day, " 10 " day ~ " 19 " day, " 20 " day ~ " 29 " day, between " 30 " day and " 31 " day, namely the ridge 64 of actuating strut 29 be positioned at same cam surface (1st ~ 4 cam surface 34a ~ 34d) upper time, similarly repeatedly carry out above action.

(switching action of the 2nd date wheel)

Next, to switching to action during " 10 " day to be described date from " 09 " day.

Fig. 8 ~ Figure 10 is the key diagram of the action (switching action) for illustration of indication mechanism 22, and is the vertical view suitable with Fig. 2.

As shown in Figure 8, in date window 15, " 09 " day is shown.That is, " 0 " of the 2nd date wheel 24 is positioned at the 2nd viewing area 15b of date window 15, and " 9 " of the 1st date wheel 23 are positioned at the 1st viewing area 15a of date window 15.

In this case, actuating strut 29 is in the 1st state, ridge 64 is positioned at the position near the inclination connecting portion 35a be connected with the 2nd cam surface 34b on the 1st cam surface 34a of cam part 34, and action gear portion 65 engages with the end of the C1 side circumferentially in the teeth portion 56 of the 2nd date wheel gear 51.

Then, as shown in Figure 9, identical with above-mentioned standard date feed motion, when the 1st date wheel 23 starts to when rotating around the C1 direction of axle center C, the 1st date pogo stick 27 becomes the 1st and to takeoff state, and the 2nd date pogo stick 28 also becomes the 2nd takeoffs state.

Now, rotated to C1 direction by the 1st date wheel 23, the ridge 64 of actuating strut 29 relatively moves relative to the 1st date wheel 23 in cam path 38 along the 1st cam surface 34a and inclination connecting portion 35a, and reaches on the 2nd cam surface 34b.In this case, along with the rotation of the 1st date wheel 23, ridge 64 and axle center C distance diametrically change (increase), and thus, actuating strut 29 swings to around the E2 direction of axis of swing E.And along with the wobbling action of actuating strut 29, the 2nd date wheel gear 51 engaged with actuating strut 29 (action gear portion 65) rotates to C1 direction circumferentially.

Then, as shown in Figure 10, the standard date feed motion with above-mentioned is identical, when the 1st jump go through pawl 46 cross internal tooth 31 of the 1st date wheel 23 when, 1st date pogo stick 27 becomes the 1st restriction state again, and the 2nd date pogo stick 28 becomes the 2nd restriction state.Now, the 2nd jump go through pawl 75 be bonded on relative to the last time engage claw 55 between rotate between the claw 55 of the position of the amount of a tooth to C1 direction, restriction the 2nd date wheel 24 rotation.

Thus, the 2nd viewing area 15b in date window 15 switches to " 1 " from " 0 " of the 2nd date wheel 24, and " 9 " of the 1st date wheel 23 in the 1st viewing area 15a switch to " 0 ", shows " 10 " day thus in date window 15.

And, except above-mentioned from " 09 " day to the switching of " 10 " day, from " 19 " day to " 20 " day with when switching from " 29 " to " 30 " day, the ridge 64 of actuating strut 29 move between each cam surface (1st ~ 4 cam surface 34a ~ 34d) time, repeatedly carry out above switching action similarly.

(inverse work of beating)

Next, as inverse work of beating, be described switching to action during " 01 " day date from " 31 " day.Figure 11, Figure 12 are the key diagrams of the elemental motion (inverse work of beating) for illustration of indication mechanism 22, and are the vertical views suitable with Fig. 2.

As shown in figure 11, in date window 15, " 31 " day is shown.That is, " 3 " of the 2nd date wheel 24 are positioned at the 2nd viewing area 15b of date window 15, and " 1 " of the 1st date wheel 23 is positioned at the 1st viewing area 15a of date window 15.

In this case, actuating strut 29 is in the 4th state, and ridge 64 is positioned at the position by migration portion 36 on the 4th cam surface 34d, and action gear portion 65 engages with the end of the C2 side circumferentially in the teeth portion 56 of the 2nd date wheel gear 51.

And, as shown in figure 12, identical with above-mentioned standard date feed motion, each date pogo stick 27,28 becomes the state of takeofing, 1st date wheel 23 rotates to C1 direction, thus, the ridge 64 of actuating strut 29 moves along the 4th cam surface 34d and migration portion 36 and reaches on the 1st cam surface 34a in cam path 38.In this case, ridge 64 and axle center C distance diametrically change (reduction), and thus, actuating strut 29 swings to around the E1 direction of axis of swing E.Thus be formed with guiding wall 37 owing to clipping ridge 64 in the opposition side of cam part 34, therefore ridge 64 is followed cam part 34 (migration portion 36) by means of this guiding wall 37 and is reliably moved.

Further, along with the wobbling action of actuating strut 29, the 2nd date wheel gear 51 engaged with actuating strut 29 (action gear portion 65) rotates (reversion) to the C2 direction around axle center C.Namely, the 4th state that actuating strut 29 engages from action gear part 65 with the end of the C2 side circumferentially the teeth portion 56 of the 2nd date wheel gear 51, directly returns the 1st state (so-called inverse beating is done) engaged with the end of the C1 side circumferentially in the teeth portion 56 of the 2nd date wheel gear 51.

Then, as shown in Figure 5, identical with above-mentioned standard date feed motion, when the 1st jump go through pawl 46 cross internal tooth 31 of the 1st date wheel 23 when, the 1st date pogo stick 27 becomes the 1st restriction state again, and the 2nd date pogo stick 28 becomes the 2nd restriction state.Now, the end that pawl 75 is engaged in the C1 side circumferentially in the claw 55 of the 2nd date wheel gear 51 is gone through in the 2nd jumping.

Thus, the 2nd viewing area 15b in date window 15 directly switches to " 0 " from " 3 " of the 2nd date wheel 24, and, 1st viewing area 15a switches to " 1 " of expression " 01 " day from " 1 " of expression " 31 " day of the 1st date wheel 23, thus, in date window 15, " 01 " day is shown.

(date is to punctual action)

Next, action when carrying out date aligning is described.

As shown in Fig. 5 ~ Fig. 7, when carrying out date aligning, first, extracting table hat 16 (with reference to Fig. 1) out 1 grade, making arbor 17 be engaged in date correction wheel 26.In this condition, via table hat 16, arbor 17 is rotated, thus, the date is revised wheel 26 and rotates.Like this, the 1st date wheel 23 is revised the rotation of wheel 26 based on the date and rotates, and thus, each date wheel 23,24 rotates by means of the action identical with above-mentioned elemental motion.

Thereby, it is possible to independently carry out date feeding, therefore, it is possible to make desired word be presented at rapidly in date window 15 at a high speed with the rotation of date finger driving wheel 25.

As mentioned above, become the 2nd by making the 2nd date pogo stick 28 to takeoff state, the rotation of the 2nd date wheel 24 is allowed to thus, and rotates along with the wobbling action of the actuating strut 29 of ridge 64 between each cam surface 34a ~ 34d during (each inclination connecting portion 35a ~ 35c and migration portion 36) movement of actuating strut 29.

In this case, if carry out date aligning at high speed as described above, then when doing against beating, the ridge 64 of (when switching from " 31 " day to " 01 " day) actuating strut 29 possibly cannot follow the change of cam part 34 (migration portion 36).Consequently, there is such situation: before actuating strut 29 returns the 1st state completely from the 4th state, each date pogo stick 27,28 returns restriction state, and the 2nd date wheel 24 does not switch to " 0 " from " 3 ", but stops at the place such as " 2 " or " 1 ".

On the other hand, in the present embodiment, follow cam part 34 (migration portion 36) owing to making ridge 64 as described above by guiding wall 37 reliably to move, therefore, even if when carrying out date aligning at high speed (particularly above-mentioned inverse work of beating), also can during each date pogo stick 27,28 returns restriction state from the state of takeofing the wobbling action of execution bar 29.

Thereby, it is possible to make the 2nd date wheel 24 return to the initial position position of " 0 " (ten be) rapidly, therefore, it is possible to reliably carry out initialization to the calendar value that the date etc. periodically repeats, thus appropriate date display can be carried out.

In addition, in the present embodiment, utilize each pogo stick 27,28 to carry out jumping to each date wheel 23,24 respectively and go through, the position of each date wheel 23,24 can be suppressed thus to offset, thus the date can be made to be presented at the position of expectation.Thereby, it is possible to improve visuality, the intention on date.

And, follow cam part 34 (migration portion 36) owing to making ridge 64 as described above by guiding wall 37 reliably to move, therefore, even if when the 2nd date pogo stick 28 and the 1st date pogo stick 27 carry out in linkage jumping go through, also can in the state of takeofing of each date pogo stick 27,28 wobbling action of reliably execution bar 29.In this case, owing to not improving the acting force to the 2nd pogo stick spring 76 that the 2nd date pogo stick 28 exerts a force yet, therefore also can the load of reducing effect on the 2nd date pogo stick 28.

And, in the present embodiment, because above-mentioned guiding wall 37 is formed in the scope of the complete cycle of cam part 34, therefore, it is possible to make ridge 64 follow in the scope of the complete cycle of cam part 34.Thereby, it is possible to carry out the date feeding of accompanying with the rotation of each date wheel 23,24 all the time rightly.

In addition, can prevent the joint of cam path 38 and ridge 64 from being removed, thus improve Reliability of Microprocessor.

In addition, to be engaged in as cam follower in the cam path 38 marked off by cam part 34 and guiding wall 37 by making ridge 64, therefore, it is possible to maintain the engagement state of cam path 38 and ridge 64 by structure simply.

And, in the indication mechanism 22 of present embodiment, by the 1st date wheel 23 and the 2nd date wheel 24 are combined, can carry out significantly corresponding with the rotation of the 1st date wheel 23 and the 2nd date wheel 24 or turned position " 01 " day ~ date of " 31 " day shows, therefore, it is possible to realize the raising of the visuality on date and the raising of intention.

Further, clock and watch 1 according to the present embodiment and movement 10, owing to possessing above-mentioned indication mechanism 22, therefore, it is possible to provide clock and watch 1 and the movement 10 of the high-quality of Reliability of Microprocessor excellence.
