Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a timepiece switching structure.

The functions of the non-calendar specification and calendar specification will be described below.

[Conventional technology]

In the conventional switching structure, as shown in the plan view of FIG. 2, 1 is a winding stem which is an external operating member, 2 is a positioning member of the winding stem 1 which is interlocked with the winding stem 1, and 3 is positioned by the rod 2 Drain formed on the doll 2
2a, which is a positioning member of the lever 2, which is a positioning member of the rod 2, 5 is a clutch wheel which is engaged with the winding stem 1 to correct the time display wheel train 6, and 7 is a time display wheel train which indicates the movement of the clutch wheel 5. 6
8 was a well-known structure composed of a wheel behind the sun.

In the case of a timepiece with a calendar having the above-described structure, when the watch is normally carried, that is, the 0th step of the winding stem is in a solid line, when the calendar is corrected, that is, the 1st step of the winding stem is in a dashed line, when the hands are set, that is, the 2nd step of the winding stem is It was configured so as to be in a state of a dotted chain line, and in a non-calendar state, it was in a state of a one-dot chain line when normally carried, and in a two-dot chain line at the time of needle matching.

[Problems to be solved by the invention] In recent years, a watch has favored a dress-like square model rather than a round model, and brings a side cut (hereinafter referred to as a side cut) on the winding stem mounting surface side closer to a band size. It is demanded that side cuts are packed to give the band and case a sense of unity. So the side cut of the movement is
The time display wheel train 6, the back wheel 8 of the day that conveys the movement of the external operation member, the small iron wheel 7, and the clutch wheel 5 are located. Further, the escaper 2 and the winding stem 1 are engaged in a position away from them. Since it is determined by a member (not shown) that guides the outer end of the movement of the winding stem 1 at the end, as one method, as for the non-calendar,
It is considered to use the first stage and the first stage.

However, in the above-described structure, if the 0th and 1st steps of the winding timepiece of the timepiece with calendar are used as they are, the normal state or the calendar correction state is brought and the hand alignment state cannot be obtained. For this reason, the shape of the rod or needle is changed so that the needle can be aligned in the first stage of the winding stem, and there are drawbacks that the parts cannot be shared, the number of types increases, and the number of processing steps increases.

Therefore, the present invention solves such a problem, and an object thereof is to provide a means for commonly using a non-calendar clock, a clock with a calendar and a switching component, and further enabling a side cut to be packed. To do.

[Means for solving problems]

The timepiece switching structure of the present invention has an engaging portion that engages with the winding stem when one is a non-calendar specification and the other is a non-calendar specification, and a normal movement of the winding stem sticking engagement portion is achieved. The feature is that the position is changed between the non-calendar specification and the non-calendar specification.

[Action]

According to the above configuration of the present invention, by changing the combination of the winding stem engaging portion of the doll, it is possible to set the normal carrying position of the non-calendar specification, the calendar specification, and the winding stem doll normal carrying position, respectively, and further switch. The parts have the same specifications, and the non-calendar specification allows the side cuts of the movement to be packed even wider than the calendar specification.

〔Example〕

FIG. 1 is a plan view of the embodiment of the present invention when the non-calendar specification is used, and the alternate long and short dash line shows the time correction state. FIG. 3 is a plan view of the embodiment of the present invention when a calendar is used. The one-dot chain line shows the calendar correction state and the two-dot chain line shows the time correction state. 4-a, 4-b, 4
FIG. 5C shows a cross-sectional view of the winding stem portion in the non-calender specification, and FIG. 5 in the calendar specification. (See Fig. 4-a and Fig. 4-b for cross-sectional views other than the winding stem portion.) 9 in Figs. 1, 3, 4-a, 4-b, 4-c and 5
Is a main plate which is a movement base frame of the timepiece, 1 is a winding stem which is an external operation member, and the winding stem 1 is a lateral hole formed in the main plate 9.
Radial positioning is performed by 9a and 9b,
Engagement of the ladle 2 with the ladle 2 enables positioning in the length direction and actuation of the ladle 2. The poster 2 has holes 2c and 2d having a posterior shaft 10 pivotally supported on the main plate 9 as a center of rotation. The hole 2c is used as a center of rotation for non-calendar specifications and the hole 2d for calendar specifications. In addition, Oshidori 2 is a winding true 1 when the non-calendar specification is used.
It has an engaging portion 2a that engages with, a winding stem 1 and an engaging portion 2b in the calendar specification, and a rotation center hole 2d or 2c when rearranged,
By changing the winding stem engaging portion 2b or 2a, it is set to change the winding stem engaging position in the non-calendar specification, the calendar specification, and the normal carrying. In the non-calendar specification, unlike the calendar specification, there is no calendar correction position and there is no need to operate the lantern in the outer peripheral direction of the movement. Therefore, the movement of the clutch wheel 5 when correcting the calendar is the movement of the winding stem 1 and the rod engagement portion. Paying attention to the fact that it can be brought closer to the center side, compared to the calendar specification, the winding stem male engaging portion 1a in the normal carrying mode is set so as to be closer to the movement center direction in the non-calendar specification. As a result, when the non-calendar specification is used, the side cut is reduced for the stroke of the winding stem 1 and the movement of the clutch wheel 5, as compared with the calender specification. As a result, the side cut has the effect of being twice as long as the target length in terms of the structure, rather than the center of the movement. Here, the front and back of Oshidori 2 are distinguished by punching 2f on the back side of the movement when the calendar specification is used, that is, in a readable manner when assembled.

Reference numeral 3 indicates a boot. The boot 3 has a dowel 9c formed on the base plate 9 as a rotation center, and the elastic portion 3a has an initial deflection, so that a rotational moment is always applied to the lever shaft 10 side. The collar 3 has a clutch wheel 5 engaged with the winding stem 1, an engaging portion 3b, and an elastic portion 3c for obtaining reset conduction between the circuit board 18, a main plate 9, a lever 2, a train wheel setting lever 11, and a circuit. The sectional clearance is determined by the pressing plate 12. In the non-calendar specification, the planar positioning of the boot 3 is performed by engaging the posterior engaging portion 3d and the dowel 2g formed on the posterior main plate side. In the non-calendar specification, the planar positioning of the rod 2 is formed on the side of the lid back and the elastic part 12a for obtaining the operation feeling (clicking force) when pulling out or pushing in the winding stem 1 formed on the circuit pressing plate 12. The planar positions of the normal carrying position and the needle turning position are determined by the engagement of the dowels 2h thus formed, and the main plate 9 is fixed by the lever pressing spring 12b provided on the circuit pressing plate.
The cross-section position is determined by being pressed against. Here, the posterior dowels 2g and 2h are formed at coaxial positions, and the holes 2c and 2d which are the center of rotation of the posterior and the dowels 2g and 2h are arranged at the same distance. As a result, when the center of rotation 2d of the rod 2 is mounted on the rod shaft 10 by changing the front and back when the calendar is used, the rod 2h engages the bolt 3 and the rod 2g engages the elastic portion 12a of the circuit pressing plate. The positions of Shidori 2 and Kanuki 3 are decided.

In this way, by using the parts for non-calendar specifications as they are and changing the front and back of the poster 2, it is possible to configure the switching of calendar use.
Further, since the rear dowels 2g and 2h and the holes 2c and 2d and the dowel distance are matched, the calendar specifications can be switched without changing the operating amount of the bolt and the bending amount of the click portion 12.

The train wheel setting lever 11 is a main plate dowel which is the rotation center of the bolt 3.
With 9c as the center of rotation, the elastic portion 11a engages with the magnetic core 13 with initial deflection, and always has a counterclockwise rotational moment. As a result, the posterior engaging portion 11b is disengaged when the posterior 2 is rotated during needle alignment, and the train wheel setting portion 11c is engaged with one of the time display wheel trains 6 by the force of the elastic portion 11a so as to be trained. ing. The cross-section positioning of the train wheel setting lever 11 is such that the elastic portion 11a has a gap and the stator 16 and the train wheel setting lever retainer 15
As a result, the train wheel setting part 11c holds the wheel and the train wheel bridge 14 and the stator 1
By 6, the posterior engaging portion 11b is determined by the hollow 3 and the circuit pressing plate 12a.

The time display wheel train 6 is corrected by a well-known structure using a small wheel 7 that engages with the clutch wheel 5 and a back wheel 8 that engages with the small wheel 7 and that engages with the time display wheel train 6. The respective plates 9 and the guide plate (9c) bushing 17 provided on the train wheel bridge allow planar and sectional positioning.

[Effect of device]

As described above, according to the present invention, two-position switching for non-calendar specifications and three-position switching for calendar specifications can be performed with a combination of the same parts, which has the effect of reducing the kinds of parts.

In addition, when the non-calendar specification is used, the center of the movement and the lever engagement position are packed more toward the center of the movement than when the calendar specification is used, so that side cuts are needed, such as an integrated watch with the same band width and complete width. It can be deployed in a wide range to suit your needs, without increasing the number of parts. In addition, when the calendar specification is used, it is possible to provide a highly reliable switching structure in which the clutch wheel position corresponding to the size of the date indicator is set to the winding stem and the lever engaging position.

Further, the lantern, the lever, the circuit pressing plate elastic portion 12a, which is a spring for locating the lever, are two-dimensionally overlapped, and the dowels 2h and 2g are coaxially provided on the lever, and in order to engage with each of them, the non-calender specification, Reliable, even with the calendar specifications, without compromising the feeling of operation. Furthermore, it is possible to do this in a plane space that is as large as a woman's size even though it is a man's size, which is suitable for downsizing.

Has the effect.

In the present invention, the shidori dowels 2h and 2g are coaxially mounted on the rotation center hole.
Although the case where the distance is the same as 2c and 2d has been described, by slightly changing the dowel width or slightly changing the distance, for example, when the calendar specification is used, the amount of deflection with the circuit pressing plate elastic part 12a is changed from the non-calender specification. It is also possible to increase the feeling of operation (clicking force), and the effect is the same even if it is slightly different.

Further, in the present invention, the embodiment in which the rotation centers 2c and 2d of the rod are changed has been described, but the rod 2 shown in FIG. 6 is used.
If one rotation center 2n is used as described above, one hole can be eliminated in terms of processing, and the effect of the present invention is even greater. (Other configurations are the same as the present embodiment although the description is omitted.) Furthermore, in the present invention, an embodiment in which the front and back of the poster 2 are rearranged for the calendar specification and the non-calendar specification has been described. As shown in Figure 7, dowel 2g
And the center distance of the rotation center 2c, 2d when the non-calendar specification,
Even if the setting is made according to the usage of the calendar specification, the rotation center 2c and the winding stem engaging portion 2a are used for the non-calendar specification, and the rotation center 2d and the winding stem engaging portion 2b are used for the calendar specification. does not change.

Further, as shown in FIG. 8, the structure is such that the dowel 2g, the winding stem engaging portion 2b for the calendar specification, and the dowel 2h, the winding stem engaging portion 2a for the non-calender specification are used with the hole 2n as the center of rotation. The effect of the device does not change.

In the present invention, the non-calendar specification and the function of the calendar specification have been described above. However, the present invention can be applied to other functions such as a function with a day of the week, a function of displaying the age of the month, a function of displaying the date of the year, a function with a hybrid, etc. Have the same effect.
