Description

The calendar mechanism of clock movement

Technical field

The present invention relates to the counting equipment in the calendar mechanism of a clock movement, form including coaxial fixing have tooth device and a planning dish (programdisk), planning dish includes:

There is the first rotation platform of external tooth;

For the device that short month is revised, by the first platform, and there is at least one first tooth, between the first advanced position and the second extrusion position, described first tooth moves relative to the first platform, at the second extrusion position, described first tooth passes to the tooth of the first platform by arranged side by side or superposition mode;

And be designed as and determine the first controlling organization moving tooth position, including at least one and the fixing first round having teeth portion part to engage.

Background technology

The equipment of this type had be carried out disclosure, particularly in the patent being numbered EP1351104B1, and the artificial UlysseNardinS.A. of this patent application, November 26 2008 year applying date. The perpetual calendar mechanism that this patent describes meets These characteristics, and wherein, the first element supporting mobile tooth is the sliding members being arranged on the first platform, to slide between active position and passive position. Relevant controlling organization includes multiple planetary gear, and they are connected on a wheel fixed by kinesiology and arrange, at least one of which planetary gear slides between its active position and passive position as sliding members. When sliding members is positioned at its active position, its gear and 24 little hour wheels mesh together, the rotation of 24 little hour wheel controlling planning dishes, enable the latter can be driven by additional step at the end of two months of non-leap-year.

It is used at the end of month in the month that natural law is 29 days and 30 days by other dishes of the first platform, drives planning dish by other steps.

Therefore, this equipment is complicated, and it comprises a lot of wheel, and some of which wheel is stacked with other wheel, additionally includes sliding members, and all these parts all pass through planning dish provides support. Therefore, being relatively large in diameter of planning dish, it may have very big thickness.

, in the patent application being numbered CH699102A2 that the name of the applicant is submitted to, to describe the annual calendar mechanism of clock movement, including structure with above in the similar planning dish of planning dish, planning dish is also coaxial with the teeth portion part that has fixed.Planning dish supports for providing with fixing first round having teeth portion part to engage, and also engages with two wheel chains of conventionally form simultaneously, this makes it possible to revise the display on date at the end of month in short month. This mechanism can provide the Bidirectional manual adjustment to date value. Each wheel chain drives one to have tooth correction to take turns, and each tooth has been truncated wedge angle. Mutual superposition is taken turns in the two correction, has rotating shaft simultaneously and compensates, and the assembling of such planning dish would not be excessively obvious.

So, although it can not consider the shorter natural law in February, this structure also relative complex, because the quantity of the wheel of planning dish support, the size of this structure is also relatively larger. Additionally, the assembling of this mechanism is also very complicated.

Other structure of the calendar mechanism of clock movement is also widely known by the people, in these structures all without providing that fixes to have teeth portion part.

A kind of method of this type is disclosed in the patent application being numbered EP1868047A1 such as VaucherManufactureFleurier application, and it relates to year calendar or perpetual calendar mechanism. The structure of this mechanism includes the first and second date wheel of mutual superposition, interrelated together by spring. The two date wheel was by 24 hours wheel drive, and the first gear in two date wheel supports the parts for date display. Engaging additionally, the two date wheel revises wheel with first and second on correction-plate respectively, correction-plate also includes three corrections for short month and is preced with, and a differential gear, is inserted in two and revises in the middle of wheel. This mechanism introduces initial compensation at the very start in short month in the middle of two date wheel, and the difference of numeral 31 and of that month natural law is depended in this compensation. This compensation dosage thinks that the second date wheel is programmed by this, makes its angular orientation be consistent with of that month actual natural law. In second stage, this mechanism released at the end of month, and the first date wheel so supporting display element just can keep consistent with the angular orientation of the second date wheel, it is ensured that within next month first day, can directly show date.

But, the production of this mechanism and set-up procedure are all extremely complex, to occupy the sizable size of bigger one piece in the plane of clock movement.

GFPIS.A. the patent application being numbered WO2013/068519A1 applied for proposes another method. This application relate to the annual calendar of clock movement or perpetual calendar mechanism, including the planning dish of the dish driven especially for date display. Planning dish includes three tracks, and the form of track depends on the natural law in current year and month, and each track is connected with retraction tooth. Planning dish is connected with demultiplication dish, it is therefore an objective to guarantee the differential speed rotation between different track. Each retraction tooth is contained in a radial slot, provides for stud and supports, stud engages with corresponding track, moves diametrically with this guide gear, completes engagement when being necessary for driving the dish showed date.

Therefore, this mechanism is because similar with mechanism before, and owing to the contiguous planning dish of needs arranges a dish, therefore surface area is also bigger.

In addition, it is also noted that the not only production of this track problematic in reality, and these tracks are provided by gear and support, and the location of they and respective gears all seems that doubtful point is a lot. And, the operating mode between track and the stud supported by tooth also needs to the abrasion considering track and/or stud a period of time, ultimately results in the fault of mechanism.Similarly, the gathering sill of tapered tooth also there will be abrasion in life-time service, after the joint accuracy rate between stud and track declines, too fast when also resulting in away. Finally, it is contemplated that the relative position between all parts, the assembling of planning dish is very complicated.

Sum it up, the above-mentioned calendar mechanism introduced in the prior art reflects, multiple possible structural approach realizes identical display purpose. It also shows these structures all relative complex, and it is thus desirable to have substantial amounts of feature, these features are for being defined these structures so that its more embodiment that it is practically impossible to dream up these mechanisms, without the situation of the evidence providing creative behavior.

Therefore, clock movement manufacturer has certain advantage in proposing the new construction of calendar mechanism of the above-mentioned type, and this structure is relatively easy compared with existing structure, and relatively reliable in use for some time.

It is appreciated that, as replacement, it is possible to make the first elastomeric element 227 include different from each other and substantially symmetric two part, to determine two independent arms, without deviating from present disclosure.

Framework also includes a protuberance 230, and its relative tooth 228,229, substantially at diametrically opposite, is designed as the sidewall with the groove 232 arranged on the first platform 224 and coordinates, and then guarantee the first component 227 correct location on the first platform and maintenance.

Each in gear 228,229 is arranged on the first platform in the additional groove 234 of setting, so that the first elastomeric element is maintained on the first platform, and guarantee that they can provide guiding radially when gear moves between the first advanced position and the second extrusion position.

First platform is dispersed with the first and second annular accommodation spaces 236,237 side by side, and the degree of depth is different, be designed as accommodation month dish 238.

Month, the common form of dish 238 was two-layer crown wheel.

Ground floor, is set to be contained in the first accommodation space 236, it is achieved the function of cam 240, its circumference has the external diameter of change. More clearly, all of cam 240 has five passive parts with same radius, and they are separated from each other by four independent plates 241, the dual plate 242 that these four plates are relevant to April, June, JIUYUE and November and relevant with February respectively. It should be noted that respectively with two passive parts in July-August and December-month by month correlation, their length is the twice of its excess-three part. The function of cam will be described below in conjunction with Fig. 3.

The internal circumference of cam 240 has the gear 244 towards its center, and its function will be introduced subsequently.

Month, the second layer of dish 238 included internal tooth 245, is designed as and is contained in the second accommodation space 237.

First platform 224 also includes a finger element 246, is designed as the support of the first and second planetary gears 248 and 249.

Additionally, the fixing teeth portion part 250 that has is arranged in the center of the first platform 224, it is assemblied in the frame element (not shown) of clock movement. Described toothed portion part supports single tooth 251, and single tooth 251 is designed as and coordinates with the first row star-wheel 248, when tooth enters into the first row star-wheel 248 front, allows the first row star-wheel 248 rotate around himself.

Being rotated through of the first row star-wheel 248 and coordinating of its internal tooth 245, make relevant with the first platform 224 month dish 238 rotate.

Month dish 238 be rotated through coordinating of the second planetary gear 249 and tooth 244, cause the rotation of the second planetary gear 249.

Second halfpace 252 is combined with the first platform 224 by screw 254, particularly makes assembly keep the structure after assembling.

Additionally, the second platform 252 has a supporting surface 256, supporting surface 256 is provided with the second elastomeric element 257, for the leap year is modified, and moves tooth 258 offer support for the 3rd.

Second component 257 includes a generally annular framework, and includes the first and second resiliency deformable portion 259,260, and each of which is connected with the 3rd side moving tooth 258 respectively.

Described framework also includes a protuberance 261, its generally with tooth 258 at diametrically opposite, be designed as and the coordinating of the groove 262 arranged on the second platform 252, to guarantee the second component 257 correct location on the second platform and to keep.

It should be noted that those skilled in the art can select other appropriate formats of the second elastomeric element according to specific needs, without deviating from present disclosure.

3rd tooth 258 is arranged in the additional groove 264 on the second platform, so that the second elastomeric element is maintained on the second platform, it is ensured that when moving between the first advanced position and the second extrusion position, and the guiding of the radial direction of tooth.

Correction-plate includes the 3rd platform 266 being arranged on the second platform 252, freely rotatable with relative second platform 252, specifically ensures that axially retaining of second component 257.

The little gear 268 that the medial support of the 3rd platform one is coaxial with described platform. Little gear 268 is designed as and engages with the second planetary gear 249, to cause the rotation relative to the first platform 224 of the 3rd platform 266.

The inner side of the 3rd platform also supports second cam 270 (on perspective view it can be seen that), and similar with the first cam 240, the circumference of the second cam 270 has the external diameter of change.More clearly, the circumference of cam 270 has three plates 271 relative to a base portion radius, and in diametrically opposite, these plates the 3rd of two in these plates is between the first two, and angle is 90 °. One passive part 272 and the 3rd plate are at diametrically opposite.

Location bar 274 coordinates with tooth 204, in a conventional manner, it is ensured that the Angle Position of planning dish 222.

What Fig. 3 showed is the details of the function of the planning dish 222 being described immediately above.

More clearly, Fig. 3 illustrates according to the particular elements of counting equipment in the present invention, the structure when it was February 28.

First in the tooth 206 that the second layer extends of 24 little hour indicators 201 is positioned at planning dish 222. As shown in Figure 3,24 little hour indicators rotate clockwise.

Not being the leap year when the current time, have February one 28 days, this means that planning dish 222 needs to rotate four steps to show first day of next month.

In this case, the 3rd moves tooth 258 (cannot see in figure 3) is in extrusion position, the position namely coordinated with the first tooth 206 of 24 little hour indicators.

It practice, the plate 271 of the second cam 270 is designed as moves applying pressure on tooth 258 in the last day in the February of non-leap-year the 3rd, so that this tooth is in extrusion position. At the end of two months of each leap year, it is relative that passive part 272 moves tooth with the 3rd so that the 3rd moves tooth 258 is in its advanced position.

When 24 little hour indicators 201 are subject to the driving of little hour wheel (as by deceleration dish at first step, these elements are well-known, therefore do not embody), the first tooth 206 moves tooth 258 from counterclockwise driving planning dish 222 forwards to move a step by the 3rd. The date of display switches to No. 29 from No. 28.

First cam 240 is arranged as its dual plate 242 and moves tooth 228 and 229 with first and be in relative position after cam is engaged, to allow two mobile teeth all in extrusion position (for the ease of the understanding to this mechanism, all show slight depression in figure 3).

Therefore, in the next step of 24 little hour indicators 201, namely after one hour, the second tooth 206 of the second layer will move tooth 228 with first and contact, thus cause planning dish 222 additional rotation one step. The display on date is from No. 29 to No. 30.

In the next step of 24 little hour indicators 201, the 3rd tooth 206 of the second layer moves tooth 229 with second and contacts, thus causes planning dish 222 additional rotation one step. The display on date switches to No. 31 from No. 30.

In the next step of 24 little hour indicators 201, the 4th tooth 208 extended in third layer contacts with the first tooth 225 of planning dish, thus causes planning dish additional rotation one step. The display on date switches to No. 1 from No. 31.

Then, move tooth 228,229 and 258 and be in the position of engagement all without with 24 little hour indicators at least 28 days.

Therefore, when 24 little hour indicators 201 rotate entirely around self from this moment on, the 4th tooth 208 only extended in third layer contacts with the first tooth 225 of planning dish 222, to cause the forwards of planning dish to move a step.

Being the leap year when the current time, have February 29 days, this means that planning dish 222 needs to rotate three steps to show first day of next month.

In this case, the 3rd moves tooth 258 is in advanced position, namely will not contact with the first tooth 206 of 24 little hour indicators. It is relative that the passive part 272 of cam 270 moves tooth 258 with the 3rd.

Therefore, first front at planning dish 222 in three teeth 206 that the second layer extends is passed through, but will not drive planning dish 222, and the 4th tooth 208 extended in third layer contacts with the first tooth 225, moves a step causing planning dish to turn.The display on date switches to No. 29 from No. 28.

Then 24 little hour indicators 201 around own rotation 20 hours, will not contact with planning dish 222.

In the rotation subsequently of 24 little hour indicators 201, the first tooth 206 extended at the second layer moves tooth 228 with first and contacts, thus causes 222 turns of planning dish to move a step. The display on date switches to No. 30 from No. 29.

In the next step of 24 little hour indicators 201, namely after one hour, the second tooth 206 of the second layer moves tooth 229 with second and contacts, thus causes planning dish 222 additional rotation one step. The display on date switches to No. 31 from No. 30.

In the next step of 24 little hour indicators, the 3rd tooth 206 of the second layer will be moved into the position that planning dish 222 is relative, but owing to the first tooth 225 is positioned at third layer, so planning dish cannot be driven, namely will not come in contact with tooth 206. The display on date remains unchanged.

In the next step of 24 little hour indicators 201, contact with the first tooth 225 of planning dish at the 4th tooth 208 of third layer, thus cause planning dish additional rotation one step. The display on date switches to No. 1 from No. 31.

Meanwhile, planning dish 222 causes two planetary gears 248 and 249 to rotate around being fixed with teeth portion part 250 around the rotation of self, because finger element 246 is combined with the first platform 224 of planning dish 222.

The tooth of the first row star-wheel 248 is along there being teeth portion part 250 circumferential slippage, and in the way of being similar to maltese cross type of device, this mode would generally adopt in some date mechanism.

Therefore, the first row star-wheel 248 is surrounded with teeth portion part 250 and rotates, but cannot around own rotation. Such structure makes to omit the location bar for the Angle Position of the particular wheel of assurance mechanism and is possibly realized.

The first row star-wheel 248 and have the connection between teeth portion part 250 simultaneously also to lock month dish 238, month the tooth 245 of dish engage with the first row star-wheel 248 relative to the first platform 224.

When planning dish 222 (namely from 28 to 31 between time) when rotating around self middle of the month, the first row star-wheel 248 rotates two steps in every month, and the relatively-stationary tooth 251 having teeth portion part 250 passes through. Gear ratio between the first row star-wheel 248 and month dish 238 is, month dish 238 proceed to the 12nd circle with the counter clockwise direction shown in Fig. 3, the first row star-wheel will move two steps each time.

Finger element 246 is positioned relative to the fixing tooth 251 having teeth portion part 250, and the rotation of dish 238 of such month just can generation before mobile tooth contacts with 24 little hour indicators 201.

According to the structure shown in Fig. 3 and above in introduction, once planning dish advances up to after the date is shown as March 1, it continues to rotate a step every day, until March 30. Meanwhile, the first row star-wheel 248 moves to the relative position of tooth 251, and rotates two steps, i.e. 1/4th of a circle, makes month dish 238 rotate 1/12nd circle in the counterclockwise direction.

Month, dish 238 was after carrying out the rotation of the above-mentioned type, is positioned at the passive part of cam 240 on the right side of dual plate 242, moves tooth 228 and 229 with first and second relative. First and second move tooth 228 and 229 enters its advanced position under the effect of the elastic part they being connected with the framework of first component 227. In this position, they come in contact all without the tooth with 24 little hour indicators 201.

3rd tooth 258 is also at advanced position in this structure, and this point can become apparent in follow-up explanation.

Therefore, at the end of month in March, owing to this month comprises 31 days, the 4th tooth 208 being only positioned at third layer can contact with planning dish 222 so that planning dish 222 takes a step forward.The display on date is from No. 31 (March) to No. 1 (April).

In rotation subsequently, it is positioned at the single plate 241 on the right side of above-mentioned passive part, moves tooth 229 with second relative so that it is its extrusion position can be returned to. First moves tooth 228 remains in advanced position, because it is also in relative position with a part for the radius with minimizing of cam 240. Layout according to plates different on cam 240, first and second move tooth effect at this moment can replace mutually, without departing from present disclosure.

In this case, No. 30 (April), it is positioned at the first tooth 206 of the second layer and moves tooth 229 with second and coordinate so that planning dish 222 takes a step forward. The display on date is from No. 30 to No. 31. In ensuing two hours, two teeth 206 afterwards pass through in the front of planning dish, but will not drive planning dish, because planning dish has not had tooth at this layer. Finally, after one hour, at a tooth of the 4th tooth 208 Contact Tooth 225 that third layer extends, to drive planning dish to rotate forward an additional step. The display on date is from No. 31 (April) to No. 1 (May).

Month, dish 238 rotated a complete circle relative to the first platform 224 in 1 year. The month that two passive parts of cam 240 are corresponding is July-August and December-January, and these moons have 31 days.

Meanwhile, month, dish 238 was with the bar 246 that is combined as a whole with the first platform 224 for fulcrum, rotated a complete circle also around the second planetary gear 249 in 1 year. In most of the time among 1 year, the tooth of the second planetary gear 249 slides along the inner periphery of cam 240, by the connection lock line star-wheel of maltese cross (MalteseCross) type, there is teeth portion part 250 the same just as the first row star-wheel 248 emphaticallyed point out above with fixing.

The month every annual meeting of tooth 244 of dish is engaged once with the second planetary gear 249, and makes it rotate two steps, i.e. be 1/4th circles at this.

Gear ratio between second planetary gear 249 and the little gear 268 of the 3rd platform 266 is, when the second planetary gear 249 rotates 1/4th circles every year, little gear 268 also rotates 1/4th circles.

Therefore, in ensuing 3 years, a plate 271 of cam 270 is located relative to the 3rd position moving tooth 258 so that it is be in its extrusion position. In 1 year (leap year) in 4 years, the passive part 272 of cam 270 is positioned at the 3rd relative position moving tooth 258 so that it is in advanced position under the effect of the power of elastic part 259 and 260 applying.

Counting equipment in the present invention is described in detail by we, especially how it calculates natural law and the cycle in leap year in different months among 1 year, and Fig. 4 to Fig. 6 introduction is how corresponding information to be transmitted between each display unit of perpetual calendar.

Fig. 4 is the perspective view of Fig. 1 parts shown. Particularly, the parts of the chain 400 showing weekly natural law can be more specifically seen in detail in this figure.

Tooth 211 on the platform 210 of 24 little hour indicators is designed as when within 24 hours, armor completes to rotate around himself every time, drives the input disc 401 of the chain showing weekly natural law.

Input disc 401 includes being designed as and contacts the breast wheel 402 coordinated with tooth 211, with and the little gear 404 that engages of first round 406 of frictional disk 407 be integrally forming, Fig. 5 will describe preferred structure example.

In this example, the connection between the platform 210 of the little hour indicator 201 of breast wheel 402 and 24 is also maltese cross type, and namely the tooth of breast wheel 402 is along the circumferential slippage of platform 210, except tooth 211 makes it pivot once a day.

The first round 406 rotation in this example can drive the second of frictional disk to take turns the rotation of 408. Second takes turns 408 engages with the little gear 410 of demultiplication dish, therein take turns 412 and engages with the tooth of the dish 3 in display sky weekly.

Therefore, every day, when 24 little hour indicators 201 once rotate around himself completing, the hole 4 in display sky weekly will move forward a step.

It should be noted that and directly driven by 24 little hour indicators for the chain showing sky weekly, namely need not by planning dish 222 because period monthly can't affect the stride of its change.

Location bar 413 is designed to ensure that the wheel 412 of demultiplication dish is in correct position.

The correction mechanism in display sky weekly is designed as and directly acts on chain 400.

Correction mechanism includes controlling bar 414, and it is designed as and is pivoted on the frame element of corresponding clock movement by the axle (embodiment) coordinated to the hole 416 on bar. The impeller that cannot see is designed as and acts on receiving plane 418, makes the bar in Fig. 4 pivot in the counterclockwise direction.

Bar 414 supports the spring leaf 420 in the rostral 422 of the free end relying on bar.

Described bar is designed as, and when it pivots, it can pass through spring leaf 420 and the star member 423 with 12 bifurcateds is applied pressure, and described star member is supported by the dish 424 of the correction for sky (day) so that it is rotated in a clockwise direction a step.

Include a wheel 426 for the dish of the correction in sky, described take turns 426 and take turns 408 kinesiologys by breast wheel 428 with the second of frictional disk 407 and be connected. In this way, it is applied to each pressure controlling lever 414 and just can tell on, make the dish 3 in display sky weekly to take a step forward.

It should be noted that input disc 401 coordinating by breast wheel 402 and platform 210 circumference, be maintained at a fixing Angle Position. So, in order to make the second of frictional disk 407 to take turns 408 rotations, the rotation of the first round 406 will not be caused simultaneously, in the middle of the two wheel, provide a friction mechanism.

On the contrary, in the driven of the display to sky weekly, the dish 424 for the correction in sky that Fig. 4 shows also is driven in the clockwise direction. But, in this case, spring leaf 420 is designed as and elastic deformation can occur, and enables the bifurcated of star member 423 to pass through in its front.

Fig. 5 describes a preferred embodiment by unrestriced mode, and the exploded view of such friction mechanism, with the angle of frictional disk 407.

The first and second of frictional disk are taken turns 406,408 and are linked together by crown wheel 430, and crown wheel generally has the shape of star, and along with the first round 406 rotates together, spring 432 and second is taken turns 408 and is combined as a whole, it is achieved be functionally similar to position bar.

Spring 432 is substantially round, and including the arm 434 of four " S " types, supported design is the rostral 436 coordinated with crown wheel 430 in couples each other, to determine the stable relative angular position between two wheels 406 and 408.

Each rostral 436 is supported by framework 438, and framework supports one and is designed as and is arranged in the protuberance 440 that the second radial slot 442 taking turns on 408 coordinates, and to guarantee the radial directed of rostral 436, is maintained with spring and takes turns the Angle Position of 408 relative to second.

By this structure, in common function, driving by 24 little hour indicators 201 when the first round 406, the rostral 436 of spring 432 just can be applied active force by crown wheel 430 so that it is rotates, simultaneously drives second and take turns 408 rotations.Then the display in the sky in week is just corrected.

At modification model, second takes turns 408 is subject to user by controlling the driving that bar 414 applies, and the dish in display sky weekly also can be made to rotate. But, in this case, the first round 406 is connected by the maltese cross type between platform 210 and input disc 401, locks in rotation. Therefore, when second takes turns 408 rotations, the deformation of the arm 434 of spring 432 will be caused, make rostral 436 can push the tooth of crown wheel 430 open. In this case, second takes turns 408 rotates around self, and the first round 406 remains in that motionless.

It should be noted that frictional disk 407 is not strictly necessary in order to realize the mechanism according to the present invention.

It practice, as replacing, input disc 401 can directly engage with the dish 424 revising sky, dish 424 is by the wheel 412 of little gear 410 and demultiplication dish and engaging of the dish 3 for showing sky weekly. In this case, but, the connection of the maltese cross type between platform 210 and the input disc 401 of foregoing 24 little hour indicators must eliminate, and to allow by control bar 414, sky weekly to be modified, does not affect the function of calendar mechanism simultaneously. Additionally, demultiplication dish can support the star member with seven bifurcateds, star member is designed as and positions bar and coordinate, it is ensured that the dish 3 for showing sky weekly is in correct position.

Further in conjunction with Fig. 4, it should be noted that by the mode having been described above, it is also possible to revise the information except sky weekly.

It is true that according to this preferred embodiment, the information relating to the date can use Shang Tiao mechanism bar 5, by the suitable mechanism revised for the date, is modified.

Especially, the latter includes the sliding pinion 450 being arranged on bar 452, and it can according to the axial location of Shang Tiao mechanism bar, and the first and second Angle Position move. From the mechanism of Fig. 4, Shang Tiao mechanism bar 5 is extracted towards the outside of movement, and bar 452 pivots clockwise, is engaged with the tooth by sliding pinion 450 with the dish 1 showed date. Meanwhile, sliding pinion also with revise wheel and 454 engage, revise wheel 454 with and Shang Tiao mechanism bar together with the sliding pinion 456 that rotates by conventional mode kinesiology connection.

Therefore, when Shang Tiao mechanism bar 5 is in the position extracted, Shang Tiao mechanism bar 5 is rotated the dish 1 showed date can be made to rotate towards one or other directions, particularly in passing through to revise wheel 454 and sliding pinion 450.

In the description of Fig. 6, the rotation of dish 1 for showing date can cause and rotates for the dish 2 showing month, can become apparent from.

Fig. 6 simplifies front view and fragmentary perspective view, illustrates the dish 1 for showing date and for showing the transmission between the dish 2 in month.

Dish 1 for showing date supports the driving ring 601 for showing month, described driving ring 601 be positioned in figure 6 dish 1 pass under perspective it can be seen that. This ring 601 is coordinated with the little gear 602 of demultiplication dish 604 by the connection of maltese cross type being mentioned above. It is true that its radius of a circle is fixing so that little gear can not rotate in most time, its tooth is in the circumferential slippage of ring.

The latter also includes two teeth 606 and 608, is designed as every month driving pinion and 602 rotates two steps in the counterclockwise direction, as non-limitative illustration.

Demultiplication dish also includes the wheel 610 rotated together with little gear 602, engages with the dish 2 in display month.Therefore dish 2 can be driven two steps every month, and the dish 1 namely every time showed date is around self completing rotation.

In this case, the Angle Position of demultiplication dish 604 is reinforced also by optional location bar 612.

With reference to Fig. 4, it can be seen that wheel 610 engages with breast wheel 701, and breast wheel 701 as the input point of chain 700, does not here do concrete introduction when the leap year. It is true that chain includes multiple dish, it is adapted to allow for the demultiplication (demultiplication) of month transition information, within the cycle of 48 months, shows the leap year.

It should be noted that the structure having been described above has certain advantage, it can use control bar 5 and carry out two-way adjustment by planning dish 222, the date value to display, or month or leap year.
