Traditionally, practical watches have had the disadvantage of being thick and large due to their focus on functionality. However, in recent years, there has been a demand for thin and slim dress function watches even for practical function watches. In order to emphasize the thinness and compactness of a watch, it is effective to move the crown position as close to the dial side as possible. The thin functional watches currently on the market have not yet achieved a design that satisfies users. The present invention provides a watch whose thinness and compactness can be further emphasized by moving the dial closer to the dial.

字板側に近づけることが不可能であるという欠点
を持つていた。 Conventionally, there is a system shown in FIGS. 1 and 2 of the Sunday correction structure using a wheel and a day collector. The stop wheel 1 has a toothed tooth 1a that engages with the date wheel 3, a big toothed tooth 1b that engages with the day collector 2, and a toothed tooth 1 that engages with the small iron wheel.
It has c. The dial wheel 1 is positioned in the Sunday correction state (FIG. 1) by means of a pusher and bolt (not shown), and the date wheel 3 is directly rotated by clockwise rotation of the winding stem 1. By rotating to the left, the day collector 2 is translated in the direction of the arrow 7 along the pins 5 and 6 set on the base plate. At this time, the toothed tooth 1a of the wheel 1 moves the date wheel 3 to the position indicated by the dashed line. The day collector 2 receives a force in the direction of arrow 8 by the spring 2a. Day collector 2
The teeth of the day star wheel 4b are moved by the movement of the day star wheel 4b, and the teeth of the day star wheel 4b are moved until the day star wheel 4b passes the top of the jump control part 9a of the date wheel holder 9.
Rotate. Furthermore, the rotation of the clutch wheel 1 continues, and at the same time that the engagement between the clockwise gear engagement portion 2b of the day collector 2 and the clockwise gear wheel disengages, the day collector 2 instantly returns in the direction of the arrow 8. When the date is corrected by clockwise rotation of the dial as described above, the day collector double tooth engaging portion 2b is structured to escape in the cross-sectional direction until it deviates from the trajectory of the wheel 1. Therefore, as shown in Figure 2, to avoid hitting the day plate 4a when running away,
Connecting the gap 10 and relief amount 12, the outer diameter of the car and the day plate 4a
must be secured between. Therefore, it is almost impossible to reduce the distance 16 from the day plate 4a to the winding stem 1, and in the conventional system, the limit was 1.5 to 2 mm. The lever-type correction method has large variations in correction stroke, and tends to cause problems such as not correcting the day of the month or sending the day collector too far. In the case where day correction is not required, the problem can be solved by bending the day-day collector double-tooth engaging portion 2b downward as shown in FIG. Alternatively, there is a possibility that the tooth shape of the day star wheel 4b may be deformed. As described above, the conventional method has the disadvantage that it is impossible to move the winding stem closer to the dial side, which has the effect of making the watch appear thinner and more compact.
本考案は巻真位置を曜板から1mm前後に設定で
き、しかも従来の欠点を無くし薄型コンパクト設
計を可能にするものである。以下に、本考案を図
面に沿つて詳しく説明する。 The present invention allows the position of the winding stem to be set approximately 1 mm from the day plate, and also eliminates the drawbacks of the conventional technology and enables a thin and compact design. The present invention will be explained in detail below with reference to the drawings.

I'm playing with it. Further, the hand wheel 1 has an O tooth 1a that engages with the date wheel 3, and an O tooth 1 that engages with the day collector 2.
(b) It has upper teeth 1c that engage with the small iron wheel 14, and there is a constant phase between the Oto teeth and the B teeth. As shown in Fig. 6, the gear teeth of the gear wheel have a serrated tooth shape with a flat surface at the tip, and the clock teeth have a trapezoidal shape as shown in Fig. 5. It has a rounded shape to reduce torque fluctuations. In the normal carrying state, the wheel wheel 1 is positioned at a neutral position by a sliding bolt (not shown) so as not to engage with the date wheel 3, day collector 2, and small iron wheel 14. Day collector 2
It has a double tooth engaging portion 2b that engages with the double tooth 1b of the gear wheel, and performs day correction. The day collector 2 is guided in a plane by pins 5 and 6 set on a main plate 13, and is positioned in the cross-sectional direction by the main plate 13 and a date wheel holder 9.

押え9により位置決めされている。 To assemble the day collector 2, insert the pin 5 into the notch 2d of the day collector, guide it to the pin 6 and position it, and then set the spring part 2a on the base plate 13. The pin 5 has a collar 5a, which prevents the day collector 2 from floating due to the spring portion 2a. Spring part 2a
is determined by the remaining wall 13a of the main plate 13,
Move day collector 2 counterclockwise and in the direction of arrow 8.
It applies rotational moment and force, and is located below the date dial 3 and is held down by a day collector holding pin 15 that is planted on the main plate 13. The degree of the day collector 2 in the direction of the arrow is determined by a pin 6 that is engaged with an engagement guide portion 2i (FIG. 7), which is a long hole formed long in a direction perpendicular to the winding stem 11. Day collector double tooth engagement portion 2b that engages with the clutch wheel double tooth 1b
has a serrated shape in which the left side is cut parallel to the winding stem 11 and the right side is cut diagonally. The slope has the effect of easily converting the rotation of the hexagonal wheel 1 into planar motion of the day collector 2, and the clockwise rotation is facilitated by the double teeth 1b. The day collector correction part 2c is bent upward,
It is located on the same cross section so as to be able to engage with the day star wheel 4b. Furthermore, the day collector 2 has the role of preventing the wheel wheel 1 from falling toward the day plate 4a when the winding stem 11 is pulled out. The date wheel holder 9 has a jump control part 9a for positioning the day wheel 4 in a two-dimensional manner and a half-opening part 9b to ensure the positioning of the day collector, and is fixed to the main plate 13 by a presser screw 16. . The date dial 3 has a serrated tooth-shaped portion 3a (see FIG. 7) having a slope on the left side in plan view, and is positioned by a base plate 13 and a date dial holder 9.

る。 Next, I will provide a more detailed explanation of the Sunday correction. Third
As shown in Figures 4 and 5, when the winding stem 11 is pulled out one step and set to the Sunday correction state, the clock wheel 1 is moved to the date wheel 3 and the day collector 2 by the sliding bolt.
It is positioned so that it meshes with the The gear wheel 1a engages with the date wheel 3, and the clockwise gear 1b engages with the day collector 2. When the winding stem 11 is rotated clockwise in this state, one tooth of the wheel tooth 1a engages with a surface cut parallel to the winding stem 11 of the date wheel 3, and the date wheel 3 is rotated counterclockwise. Rotate to adjust the date. In order to match the phase with the tooth pitch of the date wheel 3, the number of teeth on the dial 3 is set to 3. The handwheel is rotated clockwise to correct the date, and when almost the date correction is completed, the handwheel hex tooth 1b engages the day collector 2 with the slope of the hex tooth engaging portion 2b of the day collector 2, With the pin 6 as the center of rotation, parallel to the plane of the main plate 13 and clockwise,
Day collector double tooth engagement part 2b and hexagonal wheel tooth 1b
Rotate until it disengages. (The day collector is shown by a dashed line in FIG. 3.) Therefore, the day collector correcting portion 2c is moved away from the day star wheel 4b and does not engage with it, so that only the date is corrected. Day collector 2
When the pin 5 rotates, the pin 5 touches the notch 2d of the day collector 2.
run away to When the date adjustment is completed and the hand wheel 1 rotates further and the engagement between the red tooth 1b of the handwheel and the day collector red tooth engaging portion 2b is disengaged, the day collector 2 is moved to the pin 6.
Rotate counterclockwise around , and return to the initial position. By repeating the above steps, the date adjustment is completed.

形部3aの斜面の係合方向及び角度が悪いため、
日車3の歯を上方向に曲げてしまう恐れがある。 Next, when the winding stem 11 is rotated counterclockwise, a mutual reaction force due to the engagement between the slope of the gear teeth 1a and the slope of the serrated toothed portion 3a of the date wheel 3 causes the race wheel 1 and the date wheel 3 to rotate. try to keep them away from each other. However, Niksha 3
The amount of movement is the same horizontal play as in a normal calendar clock, which is extremely small. The state is shown by the dashed line in FIGS. 3 and 4.
Since the date wheel 3 is fixed by the date jumper 17, it does not rotate. At this time, the gear wheel double teeth 1b and the day collector double tooth engaging portion 2b engage with each other. Further, when the wheel 1 rotates, the day collector 2 is moved by the pins 5, 6, and the straight portion 2 of the notch 2d of the day collector 2.
The correcting portion 2c of the day collector 2 contacts the toothed portion of the day star wheel 4b and rotates the day wheel 4 clockwise. The day collector 2 is fed until the toothed tip of the day star wheel 4b passes the top of the jump control portion 9a of the date wheel holder 9. After passing the apex, the day star wheel 4b is rotated clockwise by the slope of the jumping portion 9a. After being blown away, the day star wheel 4b hits the day collector correcting portion 2c, as shown by the dashed line in FIG. 3, and remains stationary in that state until the day collector 2 returns to its original position. When the handwheel 1 further rotates and disengages from the day collector double-tooth engaging portion 2b, the day collector 2 is returned in the direction of arrow 8 by the spring portion 2a and returns to its original position. Simultaneously with the return of the day collector 2, the day star wheel 4b is positioned in a state in which it has been moved one pitch by the jump control section 9a, and the day correction is completed.
Since the return of the day collector 2 is performed by spring force, the movement speed is fast, and the straight line 2f of the correcting portion 2c is aligned with the axis of the winding stem 11 so as not to apply counterclockwise force to the day star wheel 4b during return. The cut is made at an obtuse angle from the vertical axis. The angle correction amount θ is a small amount in consideration of variations in shape and the like. Day collector 2
The notch 2d of the pin 5 insertion portion is arranged so that even when a load is applied to the day collector double tooth engagement portion 2b and the day collector is fed while rotating clockwise, the day star wheel 4b and the day star wheel 4b are formed in the second half of the correction stroke. Day collector correction section 2c
In order to ensure sufficient engagement with the protrusion 2
It has g. Therefore, when the pin 5 comes into contact with the part 2g and is further fed, the day collector 2 returns to its initial position and moves along the straight line of the straight part 2e of the day collector, shifting to the above-mentioned day correction state. I'll follow you. The above description has been made with the date wheel 3 positioned by the date jumper 17. Next, we will explain how to adjust the day of the month when the date wheel is out of position, such as when changing the date. If the position of the date wheel 3 is misaligned, the direction and angle of engagement between the toothed slope of the dial 3 and the slope of the serrated toothed portion 3a of the date wheel 3 are incorrect.
There is a risk that the teeth of the date dial 3 may be bent upward.

b部が係合し、曜修正可能となる。 In the embodiment of the present invention, as a countermeasure, a flat part is provided at the tip of the gear wheel as shown in FIG. When the toothed end of the wheel 3 hits, and while the engagement between the gear O teeth and the date wheel 3 is not achieved, the day collector C tooth engagement portion 2b and the Z wheel C gear 1 are connected.
Part b engages and the day of the month can be adjusted.

部に逃げていく。 As mentioned in the conventional system, the lever type for day of day correction has large variations in the correction stroke, and there is a high risk of insufficient correction stroke or overstroke. In an embodiment of the present invention,
Regarding the insufficient day correction stroke, it is possible to obtain a proper stroke by bending the day collector double-tooth engaging portion 2b toward the wheel 1. or,
As a countermeasure against overstroke, as shown in FIG.
However, when the day star wheel 4b develops a tension with the tooth profile and is further fed, the day collector 2 rotates clockwise around the pin 6 to prevent damage to the parts. During its operation, the pin 5 is connected to the notch 2h of the day collector 2.
He runs away to the club.
曜修正構造のコストを下げるため、部品点数の
少ないレバー式を採用することが多いが、レバー
式には曜修正感覚が良くないという欠点がある。 In order to reduce the cost of the day-of-day adjustment structure, a lever type with fewer parts is often used, but the lever type has the disadvantage that it does not have a good feel for day-of-day adjustment.
