First to the 3rd gear part 451 to 453 and little day indicator 53 engagements, and can make little day indicator 53 rotation specified angles, no matter little day indicator 53 is to be arranged in the position B (8:00 position) shown in the position A shown in the solid line (5:00 position) among Fig. 4, the single line, the position C (10:00 position) shown in still two line.Determine profile of tooth, the number of teeth and the denture length of first to the 3rd gear part 451 to 453 according to profile of tooth, the number of teeth and the rotation angle of little day indicator 53.In the present embodiment, the profile of tooth of first to the 3rd gear part 451 to 453 is identical, the same length of denture.
And, between the part that is formed with projection 433 of bar 43 and day indicator 63, being provided as the spring 46 of force application apparatus, spring 46 is to bend to the roughly linear part of U-shaped shape, as shown in Figure 2.Spring 46 is at bar 43 and be formed between the teat 252 on the date indicator keeper 25 (Fig. 3) and be locked in the appropriate location around axial region 253.Projection 433 contacts with cam 42 owing to the applying power of spring 46.Spring 46 can be integrally formed with bar 43.Date indicator keeper 25 omits in Fig. 2 and Fig. 4.
Pointer unit 50 constitutes the little day indicator 53 that has as pointer wheel, be installed in day hand 52 (Fig. 1) on the little day indicator 53 and the fan-shaped display unit 51 on the face 51.
Display unit 51 is arranged so that the interior week of the fan-shaped center of circle towards face 11, and this fan-shaped arch section is towards the center of face 11, as shown in Figure 1.51 fan-shaped arc constitutes the scale 511 in indication week with appointed interval printing or engraving to character " SUN " to " SAT " along display unit.
Little day indicator 53 according to its position and with any engagement of first to the 3rd gear part 451 to 453, and make day hand 52 (Fig. 1) motion on the turning axle 531 that is installed in location placed in the middle.
In other words, little day indicator 53 not only can be combined in position A shown in dotted lines in Figure 4 (5:00 position), and can be combined in position B (8:00 position) and position C (10:00 position), and select a conduct among the A to C of these positions to be used for position in conjunction with little day indicator 53.This with below change the pattern of the clock and watch 1A (Fig. 1) that describes relevant.
As shown in Figure 5, this little day indicator 53 and the position that is equal to of the fan-shaped center O (Fig. 1) of display unit 51 by axial support between mainboard 23 and holding plate 24.In mainboard 23 and holding plate 24, form the axis hole 231 and 241 corresponding respectively with the turning axle 531 of little day indicator 53, these axis holes 231 and 241 be formed on position A to the corresponding position of C (Fig. 4).Form hole 111 in face 11, turning axle 531 inserts and passes hole 111.
Among Fig. 6 and Fig. 7 pattern clock and watch 1B and the clock and watch 1C different with clock and watch 1A (Fig. 1) has been shown.In clock and watch 1B and 1C, display unit 51 and window 61 position in the face 11 of clock and watch 1A changes.Specifically, in clock and watch 1A, the fan-shaped center of circle of display unit 51 is arranged in the 5:00 direction, window 61 is arranged in the 12:00 direction, and in the clock and watch 1B of Fig. 6, the fan-shaped center of circle of display unit 51 is arranged in the 8:00 direction, window 61 is arranged in the 3:00 direction, and in the clock and watch 1C of Fig. 7, the fan-shaped center of circle of display unit 51 is arranged in the 10:00 direction, and window 61 is arranged in the 4:00 direction.
Though the position of display unit 51 and window 61 is different in clock and watch 1A, 1B and 1C, comprises that the movement 2 (Fig. 2) of day display device 20 is identical.Yet, be used for changing in conjunction with the position of little day indicator 53 difference according to the position of display unit 51.Specifically, in clock and watch 1A, little day indicator 53 is combined in the position A shown in the solid line among Fig. 2, is combined in the position B shown in single line in the medium and small day indicator 53 of clock and watch 1B, is combined in position C in the medium and small day indicator 53 of clock and watch 1C.
Clock and watch 1A is the orientation of display unit 51 to the difference of 1C, perhaps in other words, and the scope difference of day hand 52 rotations.Specifically, display unit 51 among clock and watch 1A (Fig. 1) and the clock and watch 1B (Fig. 6) is equipped with the approximate centre of minute hand 121 to hour hands 123 from what the fan-shaped center O of display unit 51 expanded to face 11, and the display unit 51 among the clock and watch 1C (Fig. 7) from the fan-shaped center O of display unit 51 along roughly 2:00 position be with face 11 center the direction expansion and without central authorities.The orientation of display unit 51, or the rotating range of day hand 52 changes according to the orientation of the day hand 52 installed when little day indicator 53 is combined in position A to C (Fig. 2).Therefore, when little day indicator 53 and cam 42 in conjunction with the time, regulate the position of little day indicator 53 according to the phase position of cam 42, make that the direction indication of day hand 52 overlaps with the orientation of display unit 51 in clock and watch 1A to 1C.
In the present embodiment, when little day indicator 53 was combined in position A and B (Fig. 2), the rotation angle of little day indicator 53 was approximately 80 °, and rotation angle is approximately 60 ° when it is combined in position C.Specifically, when little day indicator is combined in position C, because the 3rd gear part 453 has than first gear part 451 and the little diameter of second gear part 452, so little day indicator 53 is rotated less amount by the rotation of the 3rd gear part 453, and it is also less to be installed in the rotation angle of the day hand 52 on the little day indicator 53.The fan-shaped angle of display unit 51 (Fig. 1, Fig. 6 and Fig. 7) also is set at the angle corresponding with the rotation angle of day hand 52.
In addition, in the present embodiment, as previously mentioned, in each pattern of clock and watch 1A, 1B and 1C, window 61 changes according to the position of display unit 51 on face 11 with respect to the position of device displaying calendar date 60.This is a distance location because the position of the position of display unit 51 and window 61 separates each other in design, but structure is not limited thereto, and display unit 51 and window 61 can be located adjacent to each other.
The numeral 1 to 31 that is printed on the date indicator 63 has different orientations at clock and watch 1A in 1C, make that the character on the date indicator of seeing by window 61 63 is the top with the 12:00 direction, serves as that the bottom shows with the 6:00 direction.
The structure of clock and watch 1A, 1B and 1C has more than been described.The operation of day display device 20 then will be described.Day display device 20 is operated in an identical manner, and is combined in which location independent of position A to C among Fig. 2 with little day indicator 53.
The driving force of stepper motor is delivered to hour wheel 31 via the gear train (not shown), and hour wheel 31 rotations in per 12 hours are once perhaps rotated twice every day.Being rotated in when hour wheel 31 is delivered to day indicator driving wheel 32 of hour wheel 31 reduces by half, and the rotation 32 every days of day indicator driving wheel once.Thereby day intermediate wheel 41 is by the week rotary pawl 322 and turn over two teeth every day of day indicator driving wheel 32.Rotational speed with day indicator driving wheel 32 is a benchmark, and the driving force that then is delivered to day intermediate wheel 41 reduces to 1/7 and transmitted.
The rotation of day intermediate wheel 41 is delivered to cam 42 via day intermediate wheel 41, and whole cam 42 and day intermediate wheel 41 per seven days (weekly) rotation are once.
Cam 42 and bar 43 constitutes control modules 40, and bar 43 is owing to the rotation of cam 42 is rotated, and day hand 52 is by means of moving through display unit 51 with the little day indicator 53 of any engagement of first to the 3rd gear part 451 to 453.Specifically, because the rotation of cam 42, separate with the projection 433 of cam 42 contacts rotation center, thereby whole bar 43 rotates along the counter clockwise direction among Fig. 2 around turning axle 230 from cam 42.Because the rotation of bar 43, with little day indicator 53 (clockwise direction among Fig. 2) rotation forward of any engagement of first to the 3rd gear part 451 to 453, and the U-shaped part elastic deformation of spring 46, gather deflection degree (elastic force).Day hand 52 is according to the rotation campaign of little day indicator 53 then, thus day hand 52 scale 511 of direction display unit 51 sequentially.
Because the size T2 between the turning axle 531 of the turning axle 230 of bar 43 and little day indicator 53 approximately is the twice of the size T1 between the turning axle 425 of the turning axle 230 of bar 43 and cam 42, so bar 43 is rotation reliably by the rotation of cam 42, and bar 43 increases to the nearly twice of the displacement of the projection 433 that contacts with cam 42 at first and second gear part 451 and the displacement in 452 the denture, and therefore little day indicator 53 can reliably and easily be rotated with the rotation angle of appointment.
Thereby, when day hand 52 advances to the rearmost position 511B (Fig. 1) of scale 511 of display unit 51, bar 43 moves near the contact condition the apex portion 421 of cam 42, when day intermediate wheel 41 under this state by week rotary pawl 322 and when then rotating, cam 42 rotates with the rotation of day intermediate wheel 41 and the cycle of cam 42 stops.When the cycle of cam 42 stopped, the part that projection 433 contacts with cam 42 moved to open end 422 off and on from apex portion 421, and bar 43 is along the rotation of the clockwise direction among Fig. 2, and spring 46 rebounds.At this moment, little day indicator 53 is rotation in opposite direction owing to the rotation of bar 43, and day hand 52 is returned (reset) to the initial position 511A of the scale 511 of display unit 51.The following one-period of cam 42 begins then, day hand 52 carried out bidirectional-movement by making little day indicator 53 repeat rotation sequentially in seven day cycle, it is rotation according to bar 43 that this little day indicator 53 repeats to rotate before and after sequentially, the rotation of bar 43 then is the rotation according to cam 42, as previously mentioned.
Above-mentioned first embodiment has following effect.
(1) because the day display device 20 in clock and watch 1A to 1C is constructed such that first to the 3rd gear part 451 to 453 is formed on the bar 43, and little day indicator 53 can be combined in any position of position A to C, so can only easily make the clock and watch 1A to 1C of different patterns by the position that changes little day indicator 53 combinations.In clock and watch 1A to 1C, because the rotation center of the day hand 52 on the face 11 or rotating range difference, as the position and the orientation of display unit 51, so can easily realize the modification of external Design.
Form axis hole 231 and 241 at the position A to C that is used in conjunction with little day indicator 53 in advance, movement 2 is general between clock and watch 1A to 1C, and its advantage is the various changes for pattern, needn't change the structure of the movement 2 that comprises day display device 20.Thereby can reduce cost greatly.
(2), become complicated so can prevent the structure of replying day display device 20 because day display device 20 is made of hour wheel 31, day indicator driving wheel 32, day intermediate wheel 41, little day indicator 53 and other such gear and cam 42, bar 43 and other so simple member.Therefore, design and assembly day display device easily 20, and can stabilised quality.And, because structure is uncomplicated, so women's pattern of reduced size also is provided easily.
In addition, easily day display device 20 is placed on interior all sides of annular date indicator 63, thereby the total of movement 2 can not complicate.Thereby improved the degree of freedom of design greatly.
(3) thus guarantee coaxial rotation because hour wheel 31, day intermediate wheel 41 and cam 42 are arranged on the substantial middle of mainboard 23, so can reserve from the approximate centre of mainboard 23 to inward flange be used for bar 43 than large space, bar 43 can have different shape.Therefore, can provide three to be used for position A in conjunction with little day indicator 53 to C.Thereby can utilize a movement 2 to realize three kinds of patterns.And, a kind of cost of pattern can be reduced, and more various research and development of products can be promoted.
Be used for being not limited to three position A to C, and can be provided in conjunction with two of little day indicator 53 or four or more position in conjunction with the position of little day indicator 53.
(4) and, because the driving force of hour wheel 31 is delivered to day intermediate wheel 41 and the cam 42 that rotates reliably on same axis, so controlled the rotation of bar 43 and the operation that can stablize day display device 20 reliably by the rotation of day intermediate wheel 41 and cam 42.
(5),, bar 43 freely extends to the position A that is used in conjunction with little day indicator 53 to C so can being formed on towards the position of mainboard 23 with the dorsal part along face 11 because bar 43 is the shape of thin plate.Thereby can significantly improve design freedom.
And bar 43 can be mounted to the gear train that is arranged on the mainboard 23 by day indicator driving wheel 32 or other and cover, and this makes the easy combination of bar.Specifically, day display device 20 can easily be combined in the movement 2, and need not change the structure that has been combined in the member in the movement 2.
(6) in the device displaying calendar date 60 that uses with this day display device 20, can only easily change arrangement, the structure of design, position and shape and other this feature of window 61 in face 11 of the character on the date indicator 63, and need not change movement 2 by replacing date indicator 63 or face 11.Thereby change the position of window 61 and the character orientation that changes on the date indicator 63 becomes simple according to the direction indication of day hand 52 and the position that constitutes the display unit 51 of day display device 20.
Therefore, can provide the pattern of the clock and watch with many modification with low cost by display design in the combination device displaying calendar date 60 and the design in the day display device 20.
(7) since the side surface 430 that the thickness direction D (Fig. 3) along clock and watch 1A to 1C of bar 43 and cam 42 extends and 420 in the face of arranging, prevented at the middle body that is furnished with bar 43 and cam 42 of mainboard 23 excessive along the thickness direction D of clock and watch 1A to 1C.Specifically, because cam 42 is contained in the opening 431 of bar 43, and bar 43 is arranged to the periphery around cam 42, so the planimetric position of the planimetric position of bar 43 rotations and cam 42 rotations can roughly be arranged in same level.Therefore, day display device 20 can not become excessive along the thickness direction D of clock and watch 1A to 1C, and clock and watch 1A to 1C may be made in thinner.And, round-shaped because cam 42 forms, so can improve the intensity of bar 43.
(8) because of arch section step 455 is set at bar 43, and the diameter of first gear part 451 and second gear part 452 is different with the diameter of the 3rd gear part 453, so little day indicator 53 changes about the amount of spin of the rotation angle of bar 43 position according to little day indicator 53 combinations.Thereby the rotation angle that is arranged on the day hand 52 on the little day indicator 53 changes, and therefore can make different patterns.
And because the distance from turning axle 230 to little day indicator 53 changes according to the position of 53 combinations of little day indicator, and the rotation center of day hand 52 changes thereupon in the face 11, so can obtain different clock and watch designs.Specifically, except the position of the rotation center that changes day hand 52, can also be only by the rotation angle that step 455 changes little day indicator 53 being set in rounded portions office as the bar 43 of the part of the structure of day display device 20, thereby can carry out many design variant.
(9) and, the turning axle 230 of bar 43 and the turning axle 531 of little day indicator 53 are contained on interior all sides of annular date indicator 63, and day display device 20 is arranged to major part and is contained in the interior week of date indicator 63, and this is favourable aspect the space.
(10) turning axle 230 of bar 43 and first to the 3rd gear part 451 to 453 are arranged along roughly relative each other direction about the rotation center of hour wheel 31, perhaps in other words, the turning axle 230 of bar 43 and first to the 3rd gear part 451 to 453 are arranged to clamping hour wheel 31 on both sides.This provides favourable layout and has compared with the turning axle 230 of bar 43 and first to the 3rd gear part 451 to 453 situation disposed adjacent one another aspect the space, allow from the distance of turning axle the 230 to first to the 3rd gear part 451 to 453 of bar 43 bigger.Thereby can increase the rotation amount of the bar 43 that rotates by the rotation of cam 42, and when the rotation amount of predicting bar 43 is big, not need to increase the displacement (gap value) of cam 42.If the gap of cam 42 increases, then cam 42 passes to bar 43 with driving force, and bar 43 returns, and the power that applies on the bar 43 of therefore acting on must increase to the degree of the frictional resistance that overcomes bar 43 and cam 42 etc.Therefore can utilize cam 42 less displacements to realize the identical rotation amount of bar 43, and can reduce to operate the required motive power of day display device 20 with less torque.
And, can realize the return of bar 43 by the power that applies that acts between bar 43 and the cam 42 by means of the rotation of cam 42, and because mesh with little day indicator 53 reliably, so can prevent the vibration of day hand 52 by first to the 3rd gear part 451 to 453 of bar 43 rotations.
(11) because the size T2 from the turning axle 230 of bar 43 to the turning axle 531 that is arranged in the little day indicator 53 on first and second gear part 451 and 452 roughly is the twice from the turning axle 230 of bar 43 to the size T1 of turning axle 425, so bar 43 can rotate reliably by the rotation of cam 42, and little day indicator 53 can be reliably and easily to specify rotation angle to rotate.
The ratio of size T2 and size T1 roughly is set at 2, so that the clock and watch of common-use size can be contained in the movement 2 and member is processed easily, but this dimension scale can suitably be set in 1.5 to 2.5 the scope.If the ratio of T2 and T1 is less than 1.5, then little day indicator 53 may not can be fully rotated, if this ratio surpasses 2.5, just is difficult to day display device 20 is combined in the movement 20.
(12) in addition, because size T2 roughly is the twice (this ratio can be set arbitrarily in 1.5 to 2.5 scope) of size T1, so can in the arch section of fan-shaped bar 43, guarantee enough length, and can three position A to C that are used in conjunction with little day indicator 53 be set along first to the 3rd gear part 451 to 453 that is formed on this arch section.Thereby can only be used for easily making the clock and watch 1A to 1C of different patterns in conjunction with the position of little day indicator 53 by change.Because the position of the display unit 51 on the rotation center of day hand 52 or the face 11 is different in clock and watch 1A to 1C, so can easily realize the modification of external Design.Thereby can reduce the cost of each pattern, and promote the research and development of product.
The movement 2 that comprises day display device 20 is general in clock and watch 1A to 1C, and its advantage is not need to change the structure of day display device 20 when changing pattern.Thereby can reduce cost greatly.
As the modification of present embodiment, display unit 51 also can be provided with the orientation that extends to outer circumferential side from the inboard of face 11, and day hand 52 points to from the inboard of face 11 to the direction of outer circumferential side, as shown in Figure 8.It is corresponding to be combined in the situation that position A (solid line), position B (single line) and position C (two line) locate by display unit 51 shown in solid line, single line and the two line and the medium and small day indicator 53 of Fig. 2 among Fig. 8.
By this structure, can in Fig. 1, Fig. 6 and clock and watch 1A to 1C shown in Figure 7, use the general movement 2 in first embodiment.Specifically, can freely change day hand 52 direction of pointing to and the orientation that is arranged on the display unit 51 on the face 11 with the position that is used in conjunction with little day indicator 53 by in position A to C shown in Figure 2, regulating the position that is used in conjunction with cam 42.Like this, because can change the direction of day hand 52 sensings among the clock and watch 1A to 1C and the fan-shaped orientation of display unit 51, form many different clock and watch patterns so can utilize a movement 2.
Second embodiment
Second embodiment of the present invention then will be described.
The difference of the present embodiment and first embodiment is, is combined in the different diameter of little day indicator 53 uses that position A (Fig. 2) locates in the movement 2.
Fig. 9 is the bar 73 of the expression day display device 28 that constitutes present embodiment and the schematic plan view of little day indicator 53 and 55.In Fig. 9, in order to simplify description, little day indicator 53 or little day indicator 55 are shown, but in fact at each position A to C place, have only a little day indicator 53 or 55 to be combined in a position among the A to C of position.
In the present embodiment, be arranged in the diameter of little day indicator 55 at A place, position greater than the diameter of the little day indicator 53 that is arranged in B place, position.And the tooth pitch of little day indicator 55 is greater than the tooth pitch of little day indicator 53.Therefore, in bar 73, the tooth pitch of first gear part 751 is also greater than the tooth pitch of second gear part 452.Specifically, different in first gear part 751 with the shape of tooth in second gear part 452.
In the time of will being described in bar 43 state shown in the solid line from Fig. 9 below and rotating to state shown in two line with first gear part 751 with same diameter and the little day indicator 55 of second gear part, 452 engagements and 53 operation.The little day indicator 53 that is arranged in B place, position is rotated by meshing with second gear part 452, thereby is installed in day hand 52 rotations on the little day indicator 53.At this moment the rotation angle of day hand 52 is approximately 80 °, and the segment angle of display unit 51 is set at and these 80 ° of corresponding angles.
Be arranged among Fig. 9 A place, position little day indicator 55 diameter greater than with the diameter of the little day indicator 53 of second gear part 452 engagement, thereby the amount that this little day indicator turns over by first gear part 751 is littler than little day indicator 53, and the rotation angle that is installed in the day hand 52 on the little day indicator 55 is approximately 60 °.The segment angle of display unit 51 is corresponding with 60 ° of rotation angle of day hand 52.
Figure 10 shows clock and watch 7A, and (7B, external view 7C) wherein are combined with this day display device 28.It is corresponding to be combined in the situation that position A (solid line), position B shown in Figure 9 (single line) and position C (two line) locate respectively by display unit 51 shown in solid line, single line and the two line and little day indicator 55 and 53 among Figure 10.Thereby, can make three clock and watch patterns according to the position that is used in conjunction with little day indicator 53 or 55, be specially clock and watch 7A to 7C, and each pattern all uses the general movement 2 that comprises day display device 28.
In second embodiment, can obtain and the first embodiment identical operations effect.
And, each pattern for clock and watch 7A to 7C, except the rotation center of day hand 52 was different with the position of display unit 51, the difference of pattern also was the rotation angle of day hand 52 and the segment angle of display unit 51, and can further change the external Design of face 11.The advantage that changes pattern is, only needs to change the diameter of little day indicator 53 and 55, does not need to change any other structure of day display device 28.
