Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for displaying the alarm set state of an analog alarm wristwatch with a calendar having a date indicator and a day indicator.

[Conventional technology]

The structure of a conventional analog alarm wristwatch with a date dial and a day dial that displays the alarm set status is as shown in Japanese Patent Laid-Open No. 55-82076, in which an alarm display member formed of a cylindrical part and a flat plate part is attached to the main plate. The cylindrical portion of the alarm display member is loosely engaged with the upper pin 13b of the lever, which engages with the alarm wheel lever and pin 13a and swings with the upper pin as the center of rotation, and the hour wheel is the outer diameter of the date wheel. The flat plate portion was disposed between the front face of the date dial and the back face of the dial plate, and had a structure in which the range of swing was regulated by the alarm display plate guide.

[Problems that this invention attempts to solve]

However, in the above-mentioned conventional technology, it is necessary to provide a cylindrical portion in the alarm display member, and the process becomes difficult and expensive due to doweling with holes or bar link processing, making it impossible to reduce costs. In addition, because the alarm display member's cylindrical portion is placed between the date wheel and the dial support member, the diameter of the cutout becomes large, making it unsuitable for small watches. Because the structure is placed between the back side, a cross-sectional clearance for the date dial must be ensured, and a cross-sectional clearance for the flat plate part of the alarm display member must also be secured, so the clearance between the date dial and the dial is larger than with conventional structures. Sisters,
Cannot be made thinner. Furthermore, the date indicator is located further back than the date wheel and dial, making it difficult to see. Further, since the alarm display lever is fixed by simply loosely engaging the cylindrical portion of the alarm display plate with the pin 13b on the lever 13, it is difficult to secure the fixing force, resulting in problems such as a lack of reliability.

The present invention is intended to solve these problems, and its purpose is to provide an alarm clock with a calendar that is suitable for downsizing and thinning, is inexpensive, and has high reliability.

[Means to solve the problem]

The present invention includes an alarm set display lever (hereinafter referred to as the display lever) that indicates the alarm set state, a display lever cross section positioning member, a display lever adjustment member, and an external operation that is linked to the display lever adjustment member positioning member. A display mechanism consisting of a positioning member, a display lever adjustment member, and a part of the display lever is displayed through a hole in a day wheel having a plurality of holes closer to the center of rotation than the day character display position. It is characterized by

[Effect]

According to the above structure of the present invention, the switching section is constituted by the positioning member of the display lever positioning member and the display lever positioning member which are interlocked with the external operation member, and the display lever is driven and positioned by the operation of the switching section. Since the display lever is positioned in the cross-sectional direction by the display lever cross-sectional positioning member, the functions of each component are simplified. In other words, the shape of the parts becomes simple, the unit cost of parts can be reduced, and reliability can be improved. In addition, by having a cross-sectional positioning member for the display lever, it is possible to determine the cross-sectional position within the movement without using exterior parts that have large variations, such as ensuring the position of the position on the back of the dial, ensuring proper positioning. can. Also, the day wheel should have a plurality of holes so that the set position when normally carried corresponds to a part of the display lever, and the day wheel hole and the dial hole should be made in corresponding locations. This makes it possible to display the alarm set status near the center of the dial, which was previously impossible, and allows for a wide range of designs without changing the movement size by simply changing the dial hole diameter and day wheel hole diameter. becomes possible. It is also suitable for small watches. Furthermore, by displaying the display lever on the back side of the day wheel, there is no need to place the display lever between the date wheel and the dial as in the past, so the gap between the date wheel and the dial can be optimized, and the slim design It is also suitable for

The AL set display lever 17 rotates about the AL set display lever shaft 18 which is pivotally supported on the base plate 7, and the AL set dowel 2a and the deformed hole 17a that engages with the AL set display dowel 2a engage with each other. The positioning is performed in the plane direction, and when the AL shifter 2 is operated, the AL set display lever 17 is operated in conjunction with this (as indicated by the dashed line in the figure). Further, the display section 17b of the AL set display lever 17 is printed in red to indicate the alarm set state. Red printing will be described here, but the effect of the present invention is the same whether it is a plating color, the color of the material, or a sticker, and there are no particular restrictions on the color. Further, the AL set display lever has an elastic portion 17c, and the elastic member 7

The positioning in the plane direction is determined by a jump control part 22b made of an elastic part provided on the date wheel holder 22. Also, on the day plate 28a, there is a part on the center side of the day character display section, which is located at the rest position when normally carried.
14 corresponding to the AL set display lever display section 17b
The AL set display lever display section 17b can be displayed through the hole section 31a of the dial corresponding to the AL set display lever display section 17b. Here, the hole part 2 of the day board
8b is placed on the day plate 28a in the rest position when normally carried.
14 corresponding to the AL set display lever display section 17b
However, if the day plate 28a has a hole corresponding to the AL set display lever display part 17b in the rest position when normally carried, the number of holes does not need to be 14, and the number of holes does not need to be 14. If the area of the hole in the day wheel becomes large, such as a deformed hole with the center of rotation at
This is even more desirable because the display area from the dial hole 31a can be reduced.

Furthermore, if the hole in the dial 31 is chamfered or the like, the display of the AL set display lever display section 17b will be emphasized, which is suitable for improving the appearance.

The operation will now be explained.

At the 0th stage of the AL winding stem (this shows the state in which the alarm is stopped when normally carried), the AL display lever deformation hole 17a is pushed out by the AL Oshidori dowel 2a, so the AL set display lever shaft 18 The elastic part 17c hits the AL switch pin 23 around the center of rotation, establishing electrical continuity in the circuit and recognizing that the ringing has stopped. 15b is displayed from the dial hole 31a, and the ringing stop state is displayed.

Next, when the winding stem is pulled out to the 1st stage (here, it is normally carried and indicates the alarm sounding state), the AL oshidori dowel 2b linked to the AL winding stem 1 rotates around the AL oshidori shaft 3, and the AL When you feel a click force with the bolt presser elastic part 4a and pull it out further, the AL oshidori dowel 2b is positioned by the recess provided in the AL bolt presser elastic part 4a,
The position of the first stage is determined. At this time, the AL set display lever 17 is activated by the AL oshidori dowel 2a.
The AL set display lever is forced to rotate counterclockwise around the AL set display lever shaft 18 due to the shape of the AL set display lever deformation hole 17a. This results in
The AL set display lever elastic section 17c is connected to the AL switch pin 23 and recognizes the alarm sounding state on a separate circuit, and the AL set display lever display section 1
7b rotates to a position corresponding to the day wheel hole 28b, so that the alarm sounding state is displayed through the day plate hole 28b and the dial hole 31a.

When the AL winding stem is further pulled out to the second stage (here, the alarm time setting state is shown), the AL dowel 2b continues to rotate around the AL dowel shaft 3, and the 2 When you feel a click force at the second convex part and pull it out further, the AL dowel 2b is positioned by the second recess provided in the AL bolt presser elastic part 4a, and the second stage position is determined. At this time, the AL display lever 17 shows that the deformed hole 17a is
The shape is such that it does not operate even if the oshidori 2 rotates, and the state indicating the alarm sounding state is maintained. Also, at this time, the AL bolt 8 is pushed toward the center of the movement due to the shape of the AL rear engaging portion 8b. As a result, the AL wheel 9, which is interlocked with the AL bolt 8, meshes with the AL small iron wheel 10, and the alarm time is adjusted, and the left and right rotation of the AL winding stem 1 causes the AL hand 13 to rotate counterclockwise or clockwise. You can also adjust the alarm setting time.

Regarding the case where the AL winding stem 1 is pushed toward the center of the movement, the operation is the reverse of the above explanation, so the explanation will be omitted.

In addition, in this operation, we have explained that the alarm will stop sounding at the 0th stage of the AL winding stem, and the alarm will sound at the 1st stage, but the alarm will sound at the 0th stage of the AL winding stem, and the alarm will stop sounding at the 1st stage. Even in this case, the effect of the present invention is the same.

[Effects of this invention]

As described above, according to the present invention, the cross-sectional position of the AL set display lever can be determined with ease using the AL set display lever holder or the date dial holder. Because the dial is a part of the dial that determines the timing, it cannot be placed on the front side of the date wheel.
Appropriate agitation is ensured and reliability can be improved. Furthermore, it can be made thinner. Furthermore, by displaying the AL set display lever from the day wheel guide section, the center of rotation of the AL set display lever is not located outside the outer diameter of the date wheel as in the conventional case, which is suitable for downsizing. In addition, the design disadvantage, which was the biggest drawback of not being able to make the display larger (the larger the display, the larger the cutout diameter and the larger the case), can be resolved without increasing the size. The display part can be placed closer to the center of the movement to match the position of marks such as other manufacturer's and product names, which is highly effective in improving the appearance. In addition, in terms of processing, the parts are inexpensive because their functions are not complicated when viewed as a single unit, resulting in lower costs and improved reliability.

Furthermore, by arranging the display portion of the alarm display lever between the day wheel and the date wheel guide plate, and arranging the drive portion on the main plate at a position different in cross-section from the display portion,
Unlike when the display lever is pivoted on the date dial holder, there is no need for a gap between the date dial and the day dial to provide a pin to pivot the display lever, and furthermore, the date dial holder and the display lever are almost the same. By being located on the surface, the day wheel can be placed without making the calendar part hot.

Also, when there is no day wheel, the dial position can be lowered to the top of the date wheel holder.

Further, when the display lever is moved to the alarm set or offset state by operation of the external operating member, either the display portion of the display lever or the printed portion of the date dial guide plate is displayed in the hole of the dial and day wheel. Accordingly, the display portion of the display lever can be made smaller than the display portion of the display lever alone.

Therefore, it is possible to provide a watch that is smaller and thinner.
