DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary decoration mechanism that obtains a driving force for a rotary decoration from a timepiece mechanism, and a mold for a restriction lever used for manufacturing a restriction lever mounted on the rotary decoration mechanism.

[0002]

2. Description of the Related Art In general, a rotary decorative timepiece has a rotating shaft composed of a decorative member fixedly mounted on a vertically supported bearing shaft, and the bearing shaft is rotated periodically to rotate the rotating decorative shaft. This is a rotational movement that switches the direction in the reverse direction. In addition, the rotational movement of the rotary ornament, the rotation direction does not switch immediately, the rotation slowly slows down,
It is said to be a movement that starts to rotate slowly again in the opposite direction after stopping for a moment.

[0003] The rotary decoration mechanism for performing such a rotary motion is obtained by a method of obtaining a driving force by a combination of an electromagnet and an elastic return means, a mechanism provided with a drive mechanism separate from a timepiece mechanism, a timepiece mechanism. And the like that obtains a driving force from a motor are known.

[0004] That is, a rotary decoration mechanism that obtains a driving force from the clock mechanism extracts rotational power from the clock mechanism that performs a timekeeping function, converts the rotary motion into a rocking motion by a rocking lever or the like, and then The oscillating motion is converted into a rotational motion and transmitted to the bearing shaft to rotate the rotary ornament.

[0005]

However, in the timepiece provided with the above-described rotary decoration mechanism, the movement of the rotary decoration interferes with the clock mechanism, so that an accurate timekeeping operation cannot be performed and the time display becomes incorrect. An inconvenience has occurred.

That is, at the time of the reversing movement in which the rotating ornament switches its rotation direction from one direction to the opposite direction, not only the momentum due to the weight of the rotating ornament but also the amount of rotational moment due to the shape of the rotating ornament is added, and both of them are canceled out. A driving force for rotating in the opposite direction is required. For this reason, at the time of reversal of the rotating decoration, these become excessive loads on the timepiece mechanism, and the driving force of the timepiece mechanism is reduced, thereby hindering accurate timekeeping operation.

Further, in particular, when the rotary decoration is excessively rotated by external force or the like, there is a problem that the rocking lever, which is a rocking mechanism of the rotary decoration mechanism, is excessively bent and caught, and the entire timepiece stops.

Further, if the weight of the rotating decoration is limited in order to avoid such inconvenience, there is a disadvantage that a high-quality rotating decoration cannot be formed by using a material such as a heavy crystal.

Accordingly, the present invention provides a rotary decoration mechanism capable of performing accurate timekeeping by reducing the rotational inertia moment during the reversal movement of the rotary decoration and preventing the moment from interfering with the timepiece mechanism. It is another object of the present invention to provide a regulating lever mold used for manufacturing a separately provided regulating lever in the rotary decoration mechanism.

Therefore, since the rotating decoration can perform a slow motion that smoothly stops and starts to move, it is possible to provide an elegant luxury decoration rotating clock.

[0012] Further, by the regulating lever and the stopper,
Since the rotation decoration can be prevented from over-rotating at the time of starting or operation, the drive mechanism can be protected and safety can be improved.

[0013] In addition, since the reversing operation of the rotating decoration is supported and the weight limitation of the rotating decoration is relaxed, various kinds of rotation can be achieved by increasing the number of decorative members or using a heavy material such as crystal. Decoration can be used, and the appearance can be improved to increase the commercial value.

Further, a plurality of regulating levers having different thicknesses or widths are prepared, and a plurality of regulating levers having a thickness or width suitable for the elastic return force are selected from the plurality of different thicknesses or widths.
