Description

[Detailed description of the invention] The present invention improves the aesthetic appearance and ensures reliable operation by changing the position of the time adjustment heir used in watches, etc. when in use and when not in use. This is how it was done.

In the past, this type of mechanism corrected the time by pulling out the corrected heir and rotating it, but the corrected heir was always exposed for a long time downwards, and when making corrections, it had to be pulled out further, which spoiled the appearance and caused a problem with the spring. Those that are pulled out against force have the disadvantage that if too much of the legitimate child is pulled out, it becomes difficult to adjust the time.

The present invention has been devised in view of these points, and its contents will be explained below using illustrated examples.

1 is a modified shaft made of iron, aluminum, brass, etc., and the upper end part 2
is connected to the clock mechanism 3 via a connecting member 4, and a stopper protrusion 6 is provided at the lower end 5.

Reference numeral 7 denotes a bastard main body made of synthetic resin, which has a slide slot 8 bored in the inner axial direction and is also provided with a stopper guide slot 9.

The correction shaft 1 is loosely fitted into the slide slot 8, and the stopper protrusion 6 is loosely fitted into the stopper guide slot 9.

Therefore, when the legitimate child main body I is rotated in the state shown in FIGS. 1 and 2, the correction shaft 1 is also rotated in the same direction.

Reference numeral 10 is an inner space of the main body 7 and has a stop stepped portion 11, and the stop slot 11A is connected to the stop guide slot 9.
It is provided at right angles to the stopper protrusion 6 and is not supposed to fit with the stopper protrusion 6.

Reference numeral 12 is a stop stepped portion of the stopper guide slot 9, and reference numeral 13 is a through hole bored in the bottom of the watch case 14 into which the eldest main body 7 is loosely fitted.

Next, the operating mode of the mechanism of the present invention having the above configuration will be explained.

Now, in order to correct the time, pull out the legitimate child main body 7 in the direction of arrow A in Fig. 1, bring the stopper protrusion 6 into contact with the stop stepped portion 12 of the stopper guide slot 9, and then pull it further downward to adjust the correction shaft. When the rod 1 is pulled out and rotated in an appropriate predetermined direction, the correction shaft rod 1 also rotates in the same direction, and the clock mechanism 3
A time adjustment mechanism (not shown) within the watch can be adjusted.

Of course, it may also be used to correct the time adjustment mechanism by rotating the correction shaft 1 by pulling out and rotating the eldest main body T.

After correcting the time, push the illegitimate child body 7 in the direction of arrow B as shown in FIG. The stop slot 11A of the stop stepped portion 11 may be brought into contact with the stop bar protrusion 6 by rotating it.

By doing this, it is possible to prevent the legitimate child main body 7 from falling unnecessarily.

Therefore, the present invention has the structure and operation as described above, and the aesthetic appearance is not impaired by storing the main body next to the drawer, and in particular, by fitting the stopper protrusion into the stopper guide groove. The structure is simple and has many practical benefits, such as being able to reliably rotate the correction shaft in the same direction based on the rotation of the eldest child's body.
