In fig. 2 c, further it is shown that be used between the first head M1 and the second head M2 is interconnective Last driving element, i.e. breach E1, E2 and E3, they are intended to coordinate with the second blade L2, with by the second head M2 Drive the first head M1.According to described preferred implementation, the first head M1 includes three breach, is used for driving The date ended up with " 1 " transfers the date ended up with " 2 " to.More accurately, the first breach E1, the second breach E2 and the 3rd breach E3 is regularly distributed at the inner rim of this ring on the ring with 10 gear segments, and this can correspond to the first display segment S10- S19 or slightly misplace relative to these sections.Being separated with 3 sections between the first breach E1 and the second breach E2, the second breach E2 and the 3rd lacks It is separated with 3 sections between mouth E3, therefore, between the 3rd breach E3 and the first breach and E1, is separated with 4 sections.The location of this series breach is depended on In second blade L2 location on the second head M2, and depend on the location of display window on dial plate.According to above-mentioned excellent Selecting embodiment, wherein the second blade L2 is positioned at the display segment S22 of Figure 1B, and the first breach should correspond to show value " 0X ", And the 3rd interval V2 is associated, and its configuration to drive the first head M1 when the date transfers 02 to from 01, so that the second blade L2 coordinates with the second breach E2 subsequently, to transfer the date to 12 from 11, and finally coordinates with the 3rd breach E3, with by the date from 21 transfer 22 to.Equally, when transferring the 1st day lower January to from the 31st day this moon, the second blade L2 staggers relative to the first breach E1 One section, and under this configuration, due to the main hypodontia of i.e. reference a1 of jag of the first head M1 Region is different from aforementioned other dates ended up with " 1 ", and the first head M1 is no longer driven by the second head and complete Become the circulation of 31 days this months.With reference to series of drawing 8A-F and 9A-F subsequently, this gear mechanism being described, it is described in detail the 4th and is Column index, for transferring to from the date (01,11,21) of 1 ending with the date (02,12,22) of 2 endings, and the 5th series rope Draw, corresponding to transferring the particular case of the 1st day next month to from the 31st day.

Fig. 3 A and 3B respectively illustrates the 3-D view of the gear mechanism of the different dentitions of the first and second heads, tool 24 hours driving wheel R and the especially first main dentition D1 is had to be engaged in the first master gear plane P1, and the second main dentition D2 It is engaged in the second master gear plane.The sectional view of Fig. 3 B shows the specific setting of all gear plane, including each The equipment gear plane of head, reference is namely for the P1 ' of the first head with for the second head P2 ', have and transferred each driving gear teeth in the 1st day lower January to from the 31st day this month.According to described preferred implementation, the First main dentition D1 of one head includes edentulous area a1, and main dentition D2 of the second head includes tooth.Therefore, The first gear tooth Rd1 of the driving wheel R in one principal plane P1 can not drive the first head M1, in secondary principal plane P2 The gear teeth meshing of dentition D2 of the second gear tooth Rd2 and the second head M2 of driving wheel R.In figure 3 a, it is seen that first Auxiliary dentition D1 ' on this gear region, no longer there are the gear teeth, this can preferably separate different gear plane, described flat Face is followed successively by from top to bottom: P1, P1 ', P2 ', P2, as visible in Fig. 3 B.But, the most still it is appreciated that top phase Adjacent gear region has uniform dentition D1, D1 ' and D2, D2 ', its tooth is respectively at the first head M1 and the second head Extend on the whole thickness of M2.Each maintenance leap portion can extend on this thickness, namely for the of the first head One leap portion J1 and the second leap portion J2 for the second head.This have display segment and gear dentition is completely overlapped The setting of the head on the inner rim for the ring-shaped work pieces of the first and second heads (M1, M2) not only obtains sky Between gain, additionally it is possible to simplify the enforcement of the display programming mechanisms on date to a large extent.

Fig. 4 A and 4B respectively illustrates the three-dimensional of the gear mechanism of the different dentitions of the first head M1 and M2 similarly View, it has corrective action device B, and in particular for transferring the same instance in the 1st day lower January to from the 31st day this month Auxiliary dentition.As it was previously stated, corrective action device B is no longer engaged on the first and second master gear planes of each head In P1 and P2, but it is engaged on adjacent one another are and is clipped in first and second between the first and second master gear planes P1, P2 Equipment gear plane P1 ' and P2 ' in, this allows to be processed into correction head B has specific transverse tooth thickness degree, it is thus possible at two Engage that ground is common drives two heads in adjacent plane, be thus no longer necessary to process profile identical but in non-conterminous and not phase Hand over two plane internal messing two teeth, such as first and second gear tooth Rd1 and Rd2 of driving wheel R.Therefore, this set Put and can reduce production cost.No matter corrective action device B is positioned at where go dial plate, it should confirmation is that this head is permissible One of and four gear teeth b1-b4 being evenly distributed on its neighboring identical with profile engagement (on Fig. 4, works as corrective action When device B starts, refer to the second gear teeth b2).According to described preferred implementation, gear teeth quantity is 4 and with each other Every 90 degree, but it is to be understood that the gear teeth quantity of regulation corrective action device B periphery determines correction rate: the quantity of the gear teeth The highest, correct operation is the fastest.One of four gear teeth b1-b4 of corrective action device B two assist gear teeth of the most common engagement System, for given gear region, the profile of the two equipment gear dentition and the main tooth being simultaneously engaged with 24 hours driving wheel R The profile of system is identical.The most as shown in Figure 4 B, in the first equipment gear plane P1, ' in first auxiliary dentition D1 ' place is necessary There is auxiliary edentulous area a1 ', because there is main edentulous area a1 at the first main dentition D1 in the first master gear plane P1 (seeing Fig. 3 B).Similarly, the gear in dentition D2 ' place there is tooth, for the second equipment gear plane P2 ' is assisted second Region because also have at the second main dentition D2 in the second master gear plane P2 the gear teeth (as a comparison, see Fig. 3 B and 4B)。

From examples detailed above, should be appreciated that the 5th gear sequence corresponding to describing below in conjunction with series of drawing 9A-F, it with The relevant part of previous series Fig. 2 A-D is to depend on whether to exist the gear teeth, and each first and second head M1, M2 are respectively Have according to date, the most ongoing date value selectivity engage 24 hours driving wheel R every day gear first and second Main dentition D1, D2.This driving wheel R thus constitutes the starting point of the first main motion chain C1 for driving the first head M1, And for driving the starting point of the second main motion chain C2 of the second head M2.Different dentitions yet forms both whole programming The Part I of mechanism, for relatively direct driving each in two display heads.The programming machine showed date Structure is then by second constituted for the specific date mutual and two-way clutch between the first and second heads Part and be able to perfect, or according to the preferred embodiment shown in described and accompanying drawing, for the tens (09-> 10,19-on date > 20,29-> 30) and units transfer the date (01-> 02,11-> 12,21-> 22) of 2 to from 1.

Figure 10 is that the effect of the Bidirectional releasing mechanism between illustrating according to two display heads of the present utility model is former The schematic diagram of reason, described display head is preferably second shown in the first head M1 and Figure 1B shown in Figure 1A Head M2, wherein the controlling organization from base portion movement drives track M0 to rotate, and directly engages with driving wheel R, thus real The complete rotation of existing 24 hours, is used for indexing display device, it is recommended that corrective action device B for once a day and independent, it Such as it is activated by external control bar and rotate, as shown in earlier figures 1C.

First head M1 is selected via the first kinematic chain by 24 hours driving wheel R thus according to the date value advanced Property ground directly or indirectly drive, and the second head M2 also by 24 hours driving wheel R via the second different and independent motion Chain the most optionally drives, as mechanisms more of the prior art according to the date value advanced.But, For some dates, in the preferred implementation shown in described and accompanying drawing, such as transferred to from the monthly the 9th day the 10th day, from Monthly within the 19th day, transfer to the 20th day and transferred to the 30th day from the monthly the 29th day, for the first head M1 is attached to second First coupling mechanism 120 of head M2 can drive the second head M2 by the first head M1, rather than by 24 Hour driving wheel R directly drives, and vice versa, for transferred to the 2nd day, the 11st day from the monthly the 1st day transfer to the 12nd day with And transferred to from 21 days the 22nd day, for the second head M2 being attached to second coupling mechanism 210 of the first head M1 The first head M1 can be driven by the second head M2, rather than directly be driven by 24 hours driving wheels.Therefore, according to institute The preferred implementation stated, these coupling mechanisms are respectively used to the second index sequence shown in series of drawing 6A-G and series of drawing The 4th index sequence shown in 8A-F.

Figure 10 relates to two main motion chain C1/C2 and two assisted movement chain C1 '/C2 ', and corresponding two serial Gear plane P1/P2 and P1 '/P2 ', front with reference to as described in Fig. 3 A-B and 4A-B: the first master gear plane P1 is corresponding to wherein driving Driving wheel engages the plane of first main dentition D1 of the first head M1 by its first gear tooth Rd1, and the second master gear Plane P2 is the plane that second main dentition D2 of wherein the second head M2 engages with the second gear tooth Rd2 of driving wheel R. Similarly, the first auxiliary plane of action P1 ' is first auxiliary dentition D1 of wherein the first head M1 ' and corrective action device The plane of one gear teeth meshing of B, and the second auxiliary plane of action P2 ' refers to second auxiliary of wherein the second head M2 Dentition D2 ' with the plane of the gear teeth meshing of corrective action device B.First and second main motion chain C1/C2 divide from driving wheel R Not towards the first and second head M1/M2, and the first and second assisted movement chain C1 '/C2 ' divides from corrective action device B Not towards the first and second head M1/M2.According to described preferred embodiment, at driving wheel R, corrective action device B and Without any idler gear head in each kinematic chain between each display head, this can greatly reduce realization and be pushed away The number of parts of the display device recommended.

According to described preferred implementation, for the first head M1 being attached to the first of the second head M2 Coupling mechanism 120 preferably in described preferred implementation by drive tenon (be first, second, and third tenon respectively T1, T2 and T3) constitute, this driving tenon is driven three times by the first blade L1 in having the whole cycle in January of 31 days, should First blade L1 self be fixed to have 10 display segments and therefore have most 10 index positions limited cycle One head M1.The activation position of blade L1 is designated as " PE " on Fig. 6 G, using the abbreviation as " activation point ", this position by The fixing gear region K being arranged on plate P defines, and this gear region at least extends on the width of a display segment, and Should at least drive the second head M2, with to tens carry, i.e. transfer to from the 9th day the 10th day, the 19th day and transfer to 20 days and transferred the 30th day to from the 29th day.Should be appreciated that according to unshowned change programme, this fixed gear region K will be relatively Extend on big width, and maintain the activation point " PE " of the first blade L1, be applied not only to tens carry, be additionally operable to subsequently Transfer to " 1 " from " 0 ", i.e. for the index corresponding to the 3rd sequence index described in above-mentioned reference series of drawing 7A-F.

According to described preferred implementation, for the second head M2 being attached to the second of the first head M1 Coupling mechanism 210 includes driving breach (respectively first, second, and third breach E1, E2, E3), and described driving breach is by solid Determine to the second head M2 the second blade L2 location being arranged to tilt the inner rim towards the first head M1.According to Described preferred implementation, in order to enable to transfer the 2nd day from the 1st day to, transferred to from the 11st day the 12nd day and transferred to from the 21st day 22nd day, no longer drove subsequently for this month last day, the 31st day the most also ended up with numeral " 1 ", it is necessary to exist with predetermined Three breach that mode the is spaced circulation of 3/3/4 (on 10 angularly section with).

Although according to the preferred implementation recommended, the first and second coupling mechanisms between two display heads 120,210 the flexible blade coordinated respectively is used with tenon and breach, it is to be understood that, other change programmes are also feasible, Use other kinds of driving element, especially there is the bidentate system of suitable profile.Such as, pivotably fold the gear teeth and will replace the One flexible blade L1, and act on operating position all the time by means of fixed gear region K；It also can be replaced the long gear teeth, And the radially protruding part in the gear plane of the pivot gear teeth also engage another type of driving element, such as replacing tenon Point, this part is only functionally represented limit element, and thus without the need for including the public rotation along two heads Shaft axis, it is perpendicular to its display plane and the pin that arranges, as according to shown preferred implementation.It is likewise possible to use Other drive and limit element is for the second coupling mechanism 210, and wherein flexible member is not necessarily.So, bidentate system also may be used Being suitable for implementing desired coupling mechanism, a profile of described two-wheel tooth is arranged on the first head M1, and with It is arranged on another form fit on the second head M2.

The advantage of shown preferred implementation is, flexible or inflexibility the preparation method driving element can pass through Punching press realizes, and the most cost-effective.

Fig. 6 A and 6D shows and transferred this moon to the 10th day from the 9th day, and more generally explanation transfers more high-order ten to Number and transferred the 10th day this month from the 9th day to and transferred the 20th day and transferred to from the 29th day second rope of the 30th day from the 19th day to Draw the function of sequence.In this second index sequence, the second head unitary rotation, because the first head M1 drives the Two head M2.As visible in the details in Fig. 6 G, the fixed gear region K of holding plate P promote the first blade L1 court At outside to operating position, i.e. reference is the activation point of " E ", in order to drive the first tenon T1, is used for transferring to One tens.Should be appreciated that similar coupling mechanism, by means of identical gear region K, is used for carrying out from each tens Change, but the first blade L1 will be pushed to the second tenon T2 in activation point PE and transfer to the 20th day for from the 19th day by it, And push the 3rd tenon T3 to and transfer the 30th day to for from the 29th day.

As visible in Fig. 6 B, the second blade L2 positions relative to window all the time, and hereafter, the first of the first head M1 is Last units of row show value I1 positions relative to the second window F2 too.As it was previously stated, and as in Fig. 6 C Visible, hereafter, this second blade L2 is positioned in the second breach E2.In order to cover first edentulous area of the second head M2 The existence of a21, it is still towards 21 hours driving wheel R, and does not therefore drive the second head M2 to rotate, and first lives Dynamic device M1 self is driven (for clarity sake, without reference on accompanying drawing) by the gear teeth being positioned in the first gear dentition D1, For coupling the second head M2's by the first tenon T1 driven by the first blade L1 via the first head M1 First coupling mechanism 120 can drive the second head M2 and the first head M1 of display segment along shown in Fig. 6 B and 6C Jointly rotate in direction of rotation.In fact visible in Fig. 6 E and 6F, the second blade L2 all the time against the second breach E2, but its Stagger a display segment (as from Fig. 6 E towards bottom, this is top view, and towards top from Fig. 6 F, it is to regard at the end Figure).

The 3rd sequence shown in series of drawing 7A and 7F shows and transferred this moon to the 11st day from the 10th day this moon, and more typically Ground is intended to explanation and transfers the index on the date ended up by numeral " 1 " from the date ended up by digital " 0 " to, can be from this moon the 10th It transfers the 11st day to, transferred to the 21st day from the 20th day this moon or transferred the 31st day to from the 30th day this moon.According to described preferred Embodiment, the type of drive of first and second head M1, M2 is very simple, because first master of the first head M1 Second main dentition D2 of dentition D1 and the second head M2 be each contained in driving wheel R engagement gear teeth, from without Will be according to coupling mechanism of the present utility model.It will be appreciated, however, that as it was previously stated, according to another embodiment unshowned, can To increase fixed gear region K so that the first blade L1 is still promoted towards outside at activation point PE, in order to still drive the One tenon T1, thus drive it without any gear teeth in place of second main dentition D2 of the second head M2, because will be by First head M1 couples, the most all the time front according to reference to the second sequence index described in series of drawing during use the One coupling mechanism 120.If additionally, be always positioned in the second breach E2 at this position the second blade L2, can remove herein One gear teeth of the first main dentition D1, and in this case, the first head M1 will be driven by the second head M2.This Also being similarly applicable for transferring 21 to from the date 20, wherein the first blade L1 can drive the second tenon T2 all the time, or as choosing Selecting ground, the second blade L2 can drive the first head M1 all the time by the 3rd breach E3；But, for from the date 30 turns Being 31, the only first blade L1 drives the 3rd tenon T3 all the time, but for the second blade L2 for driving the first head M1 Any alternative infeasible because it staggers a gear region or a display segment relative to the first breach E1, as Shown in aforesaid series of drawing 9A-F.For unshowned alternate embodiment, it will be appreciated that the first and second auxiliary dentitions D1 ' With D2 ' will adjust according to the first and second main dentitions D1 changed and the profile of D2.Fig. 7 B and 7C respectively illustrates the first He The top view of the relative position of the second head M1 with M2 and bottom view, wherein use two work simultaneously rotated when index The direction of rotation of dynamic device.Fig. 7 E and 7D shows the index position of the auxiliary display segment of two heads M1, M2, Qi Zhong Two blade L2 still engage with the second breach, but two display segments below window are by the first display window F1 and the second display window F2 is formed.For transferring to the 21st day from the 20th of month the day, the angle position of the first head M1 is constant, but the second head Second blade of M2 is positioned on dial plate at about 3, and as illustrated in fig. 7f, in the 3rd breach E3, the only second blade L2 is moved And be positioned in the 3rd breach E3.Fig. 7 B/ for transferring to the 31st day from the 30th day, before the position of the first head M1 and index In Fig. 7 E/7F after 7C and index identical, and the position that the position of the second head M2 is occupied in Fig. 9 B and 9C with it Put identical.

The 4th index sequence shown in Fig. 8 A-8F corresponding to from units with the date that " 1 " ends up transfer to units with The date index on the date that " 2 " end up, i.e. transferred to from the 1st of this month the day the 2nd day, the 11st day and transferring to the 12nd day and from the 21st day Transfer the 22nd day to.For these dates, the first head M1 is positioned to make the first dentition D1 have the master shown in Fig. 8 B and lacks Tooth region a1, to allow to drive the second head M2 at the end of month, i.e. for the date " 31 " ended up with " 1 " equally, rather than the One head M1, this is the purpose of the 5th sequence shown in Fig. 9 A-9F subsequently, and this in fact defines hereafter institute The special circumstances of the 4th sequence stated.

For the 11st day this moon, the second blade L2 of the second head M2 was engaged on the second breach of the first head In E2, thus, even if there is no the gear teeth in first main dentition D1 of the first head M1, also driven by the second head M2 First head M1, by the direction of rotation shown in the 24 hours driving wheel R of supplementary display segment arrow in Fig. 8 B and 8C Drive.Therefore, the relative position of two heads maintains between Fig. 8 B/C and 8E/F constant, this is because each movable dress Put the numeral having rotated to show on the second window F2 of window that units is " 2 ", and the second blade L2 location and the The units of first show value of one head M1 is overlapping equal to the display segment of the numeral of " 9 ", is likely located at 6 point on dial plate Place.As identical in all other index sequence aforementioned, monthly repeat this sequence three times, compared with shown in series of drawing 8A-8F, from this moon Unique change of the index transferring the 2nd day on the 1st day is location the second blade L2 and the first breach E1 engagement, rather than the second breach E2, wherein at the end of index, the second blade L2 transfers dial plate to about the angle position on dial plate about 10 that positions of window At upper about 9, shown in Fig. 5 A/5B of the first index sequence the most as the aforementioned, and calendar mechanism connects between progressive stage in month Connect thereon.In order to be transferred to the 22nd day from the 21st day on the date of this month, the second blade L2 will engage the 3rd breach E3, and second Position on dial plate about 3, the angle position of blade L2, transfers the position at 2 on dial plate to.

May be at the end of each of index for three of the 4th index sequence, it should be noted that driving wheel R from Wherein first main dentition D1 of the first head M1 is configured with the display segment of main edentulous area a1, transfers wherein the second main dentition to D2 is configured with next display segment of edentulous area, it may be assumed that for the 2nd day this month the first edentulous area a21 (in Fig. 5 B visible), use The second edentulous area a22 in the 12nd day this month and the 3rd edentulous area a23 for the 22nd day this month.

Series of drawing 9A-9F relates to the 5th last index sequence, and it is contrary with aforementioned four index sequence, the most only carries out Once, this is from aforementioned the most monthly to carry out four other index sequence of three times different.Such as front reference Fig. 8 A-F relative to the 4th Described in index sequence, the 5th index sequence is the particular case of the 4th index sequence, in this particular case, and the second head M2 is only driven by the second main dentition D2, and without the main edentulous area a21 in the gear teeth, i.e. Fig. 9 B at the first main dentition D1, and Between the second and first display head, lack coupling mechanism mean that the second head M2 individually rotates, and first lives Dynamic device M1 does not rotates.

As comparison diagram 9A and 9D understands, which show respectively before and after the index transferring the 1st day next month from the 31st day to Show value, in Fig. 9 B and 9C, the angle position of visible first head M1 is not moved, during indexing in Fig. 9 E and 9F Visible.Therefore the edentulous area identical with Fig. 9 B, the most main edentulous area a21 can be found on Fig. 9 E.As visible in Fig. 9 C, due to The relative angular position of the first head M1 and the second head M2 makes the second blade L2 not be engaged on the first breach E1 In, thus any the most infeasible by being connected with each other the driving carried out.Therefore, after the second head M2 rotates, the second leaf Sheet L2 drives the first head M1 again by the first breach E1, can confirm on Fig. 9 F the 5th index sequence it After engage each other, this 4th index sequence for transferring the 2nd day this month to from the 1st day this month allowing to describe in the preceding paragraphs Drive during the index of row.

Once perform this index, be achieved that a complete display circulation, and two heads are relative to window Angle position identical, the units U numeral that the second of the i.e. second head M2 fixes blade and value is " 2 " is positioned at dial plate At upper about 10, say, that angular segments thereon is corresponding to the display window formed by the first and second window F1 and F2, and this shows Show that window is positioned on dial plate at 9.

Other the alternative displaying schemes that hereinafter should be appreciated that the big date type display device for being recommended are feasible , especially have by means of its word tangential orientation rather than be radially disposed in the show value on each head and show Showing, this is contrary with described preferred implementation.In this case, any interval V on the first head M1 and second lives Space on dynamic device M2, for the juxtaposition of show value, the most essential, owing to show value is along different geometry rings Different two concentric rings of shape space, such as internal diameter are advanced, and it is the most overlapping, or the concentric display that dish and ring are formed Head, nonconcentric(al) two heads that even its series show value is crossed on window partly, never overlapping, with aobvious Show the date.Other are used to program the display change programme of the bindiny mechanism between two display heads, equally feasible , especially have radially and the most flexible gear teeth of non-perpendicular engagement.
