Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a rotating decoration mechanism for a watch that uses a rotating decoration that rotates using magnetic action to provide decoration.

(Prior Art) In general, the rotating decoration of a watch has received a lot of attention for its function as a kind of decoration, which has nothing to do with the original watch mechanism.

Conventionally, in order to enhance the decorativeness of the entire watch, a rotating decoration was separately assembled on the watch, and the spindle 6 was supported via the bearing 8 of the stand 4, and the upper end of the spindle was A decoration body 10 is fixed, and a balance magnet body 12 is fixed to the lower end. The balance magnet body 12 has magnets 1 at the ends of the upper and lower support plates 14 and 16.
8, 20 and balance weights 22, 24 are fixed respectively. A drive coil 26 is provided between the magnets 18 and 20 to impart magnetic action to the magnets 18 and 20.

On the other hand, a plurality of magnets 28 are provided at regular intervals on the outer edge of the main rotating decoration 2. Adjacent to the main rotating ornament 2, a subordinate rotating ornament 30, which is a subordinate movable ornament, is provided.
This sub-rotating decoration 30 is a decorative body rotatably supported on the support base 4 with a support shaft 32. A plurality of magnets 34 are also provided at regular intervals on the sub-rotary decoration 30, facing the magnets 28 provided on the main rotary decoration 2. This magnet 34 is provided at the outer edge of the subordinate rotating decoration 30 at a position near the rotation locus of the magnet 28 and at a position where the magnet 28 exerts its magnetic action when facing the magnet 28.

Therefore, when the main rotating ornament 2 rotates due to the magnetic action of the drive coil 26 and the magnets 18 and 20, the magnet 28 of the main rotating ornament 2 is attached to the magnet 34 of the subordinate rotating ornament 30 as the main rotating ornament 2 rotates. exerts a magnetic effect. The attraction and repulsion between the magnets 28 and 34 due to this magnetic action causes the slave rotating decoration 30 to rotate.

In the embodiment described above, the subordinate rotating ornament 30 is configured to rotate along with the main rotating ornament 2, but the subordinate movable ornament may also be configured to move up and down. That is, the magnet 28 of the main rotating decoration 2
A magnet is positioned opposite the magnet 28 at a position near the rotation locus and where its magnetic action is exerted, and a plurality of magnets are provided on the periphery of the vertically movable ornament that is the subordinate movable ornament. This vertically movable decoration moves in the vertical direction as the main rotary decoration rotates, and its magnet 28 exerts a magnetic action on the magnet of the vertically movable decoration.

Furthermore, the subordinate movable ornament can be swung in addition to rotating or moving up and down. That is, a plurality of magnets are supported by leaf springs around the main rotating ornament, and when the magnets pass as the main rotating ornament rotates, the magnets of the subordinate movable ornament are attracted and move in the radial direction.

(Effects of the invention) As explained above, according to the invention, since the secondary movable ornament is provided that corresponds to the main rotating ornament, a variety of movements can be obtained as a whole, thereby further enhancing the decorativeness of the watch. can be done.

Furthermore, according to the present invention, the rotational movement of the existing rotating decoration is used as is to guide the decorative subordinate movable decoration, so there is no need to add any complicated drive mechanism, and the structure is simple and versatile. You can get decorations.
