Background technology
Known a kind of big date indication mechanism for date of observation demonstration easily, will show on the date greatlyyer.
The date disc that the big date indication mechanism that will show on the date greatlyyer normally passes through separately shows position date and ten dates; Reduce the quantity of the date literal of each date disc; Increasing an area that the date literal is shared, thus can with the date literal show big (patent documentation 1～3 etc.).
But, showing with a date disc under the situation on position date, in big date indication mechanism in the past; Demonstration is from 31 dates of 1 to 31, that is, and and " 1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1 "; So; In order to ensure the occupied area of each literal, be difficult to avoid date disc to become big, date disc in fact become near the inner peripheral that expands to watchcase than macrostructure.That is, in this big date indication mechanism, though various researchs have been carried out in the demonstration on " ten " position date, the demonstration on individual position date still depends on circular bigger date disc.Consequently, even want the zone in the dial plate of clock and watch is used for other demonstrations, also be difficult to avoid producing various restrictions.
In addition, following structure has been proposed also: overlapping with one heart multi-disc date disc, and be set the date of window with the date disc of the downside that can detect by an unaided eye at the date disc that is positioned at upside, thus make the quantity on the date of every date disc reduce (for example patent documentation 4 and 5).
But, in this case because date disc shows two digits (date), so become near the inner peripheral that expands to watchcase than the macrostructure this point on, be same also with in the past common big date indication mechanism.And, in this case, because overlapping big date disc, so be difficult to avoid the clock and watch thickening.Have again, in this case, also be difficult to avoid to become to be used for the complicated structure of otherwise special use fully.
In addition; Showing with a date disc under the situation on position date; Also proposed with " 1,2,3,4,5,6,7,8,9,0 " these 10 textual representation, but in this case, for control simultaneously shows a date disc on position date and other date disc both sides' the rotation that shows ten dates; Adopt program mode gear (program gear), then be difficult to avoid the complicated of the structure that produces by this program mode gear.

In big date indication mechanism of the present invention, be provided with " switching mechanism; said switching mechanism engages between the disengaging configuration and movably first and second date finger driving wheel supported at the first engaging disengaging configuration and second; be positioned at said first when engaging disengaging configuration at said switching mechanism; first date finger driving wheel is set in the first date finger driving wheel working position; and second date finger driving wheel is set in second of second date finger driving wheel and changes the forbidden second date finger driving wheel off-position that engages between second date gear of day claw and second date wheel; Be positioned at said second engaging during disengaging configuration at said switching mechanism; Second of second date finger driving wheel changes day claw and is set in the second date finger driving wheel working position that can engage with second date gear of second date wheel; And; First date finger driving wheel is set in first of first date finger driving wheel and changes the forbidden first date finger driving wheel off-position that engages between first date gear of day claw and first date wheel "; so, be set at switching mechanism under the situation of the first engaging disengaging configuration, first of first date finger driving wheel changes the amount that day claw makes a tooth of first date wheel rotation on the one; per 10 days of the rotation of this first date wheel through day feed gear wheel be passed to second date wheel, make the rotation of second date wheel thus and carry out the big date and show.Here, be set at switching mechanism under the situation of the first engaging disengaging configuration, be under an embargo with engaging between second date gear of second date wheel, so the rotation of first date wheel can not receive the influence of the rotation of second date wheel.Here, in big date indication mechanism of the present invention, owing to have above-mentioned switching mechanism, so do not need the program mode gear of labyrinth.
In addition; In big date indication mechanism of the present invention; Owing to be provided with the switching mechanism that constitutes as described above; So be set at switching mechanism under the situation of the second engaging disengaging configuration, second of second date finger driving wheel changes a day claw and makes the rotation of second date wheel, makes second date wheel be back to initial position thus.At this moment; Day feeding breast wheel is followed the rotation of second date wheel and is rotated; But under the situation of " 31 " day, the carry tooth is positioned at from the day position left of feed gear wheel, thus first date wheel not can because of this day feed wheel rotation rotate; The demonstration on big date becomes " 01 " from " 31 ", thereby returns the initial position show state of (first day).
In big date indication mechanism of the present invention, preferably, first date gear possesses 10 teeth.
Under this situation,, do not show " 31 " individual date with not needing as typical big date indication mechanism in the past yet,, can carry out the big date to show so can guarantee the space of each literal fully even show that first date disc on position date is smaller.
In big date indication mechanism of the present invention; Preferably; The carry tooth of first date gear forms than other the transverse tooth thickness that constitutes this first date gear; Day feeding breast wheel comprises feeding neutral gear portion on the firstth and feeding neutral gear portion on the secondth, and feeding neutral gear portion possessed a plurality of first day feeding center tooth in said first day, and feeding neutral gear portion was identical with the tooth pitch of this feeding neutral gear portion on the firstth in said second day; Feeding neutral gear portion on the firstth of feeding neutral gear portion and this overlapped integratedly in said second day; Feeding neutral gear portion possessed a plurality of second day feeding center tooth in said second day, compared the thin thickness of the little and said second day feeding center tooth of the width of the paddy portion of said second day feeding center tooth with feeding center tooth on the firstth; Second date gear and feeding center tooth engagement on the secondth, the carry tooth of first date gear and feeding center tooth engagement on the firstth.
In this case, first date gear and second date gear are directly engaged with a day feeding breast wheel, and can be with occupying that the space is suppressed to bottom line and with the complicated bottom line that is suppressed to of structure.In addition, for example, the carry tooth that also can not make first date gear is than other the transverse tooth thickness that constitutes this first date gear, and makes it longer than other the tooth that constitutes this first date gear.
In big date indication mechanism of the present invention, preferably, have the jump first date keeper of control action and of first date gear to the jump second date keeper of control action of second date gear.
In this case; Because first date wheel and second date wheel are proofreaied and correct at predetermined position of rotation reliably; So can make first date disc and second date disc stop at predetermined position of rotation reliably, thereby can suitably carry out showing through the date of date window.
In big date indication mechanism of the present invention; Preferably; Switching mechanism has: date finger driving wheel bar, said date finger driving wheel bar possess with the supporting of first date finger driving wheel and second date finger driving wheel for the bar main body that can rotate freely and with this bar main body be the first date cam follower and the second date cam follower of one; The first date cam, the said first date cam and first date gear are one, and the said first date cam supplies the cam follower engaging of first date; And the second date cam, the said second date cam and second date gear are one, and the said second date cam supplies the cam follower engaging of second date.
In this case; Since can through the first date cam and the first date cam follower engage and the second date cam and engaging of the second date cam follower limit the position of rotation of bar main body; So rotate in other words through making the rotation of bar main body; Rotated by the rotation center of this bar body abutment for first and second date finger driving wheel that can rotate freely; First and second position of changing day claw is switched thus, thereby switching mechanism can engage between the disengaging configuration and switches at the first engaging disengaging configuration and second.
In big date indication mechanism of the present invention; Preferably, when becoming 31, the date finger driving wheel bar rotates; Make the date cam follower of winning be embedded in the recess of the first date cam; The second date cam follower is embedded in the recess of the second date cam simultaneously, and switching mechanism is in the second engaging disengaging configuration, and the amount that second date gear of second date wheel rotates a tooth by second date finger driving wheel is to be back to initial position.
In this case; On the one hand; When becoming 31, switching mechanism is in the second engaging disengaging configuration, and second date finger driving wheel is set at the second date finger driving wheel working position; Utilize second to change day claw and engage with second date gear and make second date wheel rotate the amount of a tooth of second date gear, thereby be back to initial position (ten is 0 position).At this moment, first date wheel is not rotated and is remained on the state that shows " 1 " as a position date, shows to become " 01 " from " 31 ".
In addition, not rotate and be retained in original position be because following two reasons to first date wheel.That is:
(1) is under the situation of the second engaging disengaging configuration at switching mechanism; First date finger driving wheel is in the first date finger driving wheel off-position that does not engage with first date gear; Even so the rotation of first date finger driving wheel, first date gear does not rotate yet, first date disc does not rotate.
(2) under situation about day shifting to " 01 " from " 31 " day; When second date wheel is back to the reference position; The amount that day feeding breast wheel also rotates a tooth; But the carry tooth of first date gear moment of " 31 " day from day feed wheel the position that engages of tooth portion leave, so first date gear can not rotate because of the rotation of day feeding breast wheel, first date disc is retained in the state of demonstration " 1 ".That is, in this big date indication mechanism, the demonstration of the demonstration of " 1 " of " 31 " day and " 01 " day " 1 " is that the identical date literal through first date disc shows continuously.Therefore, first date disc preferably has 10 literal portions that from " 1 " to " 9 " reaches " 0 ".But, if desired, so long as 10 multiple also can be more than 20 or 20.
In big date indication mechanism of the present invention; Preferably, have elastic component, said elastic component applies the elastic force towards the direction of second turned position from first turned position to the bar main body; When switching mechanism is in the first engaging disengaging configuration; The bar main body is in said first turned position, and when switching mechanism was in the second engaging disengaging configuration, the bar main body was in second turned position.
In this case; The date finger driving wheel bar rotates; Make the date cam follower of winning be embedded in the recess of the first date cam, the second date cam follower is embedded in the recess of the second date cam simultaneously, and elastic component applies the inclined to one side power of elasticity that is in the direction of the second engaging disengaging configuration towards switching mechanism to the bar main body; Thus, can locate the date finger driving wheel bar reliably.But, state the illustrated embodiment that kind after for example, the engagement between the gear part of the gear part through changing day breast wheel and first and second date finger driving wheel and the date finger driving wheel bar is applied under the situation of rotating inclined to one side power also can not be provided with elastic component.
In big date indication mechanism of the present invention, preferably, the center of rotation axis of date finger driving wheel bar is consistent with the rotary middle spindle that changes day breast wheel that the rotation with hour wheel is delivered to first and second date finger driving wheel.
In this case, the bar main body of date finger driving wheel bar is rotated, just can engage disengaging configuration and set first and second.
In big date indication mechanism of the present invention, preferably, first date gear has 10 teeth, and second date gear has 8 teeth.
In this case; Because first date disc just can satisfy with the date of minimal quantity, thus the numeral on a data representing position date significantly, can also be as 8 numerals of numeral demonstration of representing ten dates; So; Through showing 4 numerals of from " 0 " to " 3 " for twice repeatedly, occupy with the size of roughly the same degree at first date disc and second date disc under the state in zone of same degree, can show date with the size of same degree.
In clock and watch of the present invention, for realizing above-mentioned purpose, big date indication mechanism with above-mentioned that kind.
