ACCESSORY/DECORATION THAT OPENS LIKE A FLOWER

摘要

As a new design, when making part of a decoration rotatable, there is a tendency for this to result in an unnecessarily complex structure, and it was difficult to apply such structures to small decorations such as rings, due to considerations such as strength and smooth movement. Solution: The present invention was configured as follows in order to provide a decoration which, even if having a small size, has a simple structure and strength, and opens like a flower. The decoration has a configuration whereby one of a group of movable petals (1) having a calculated curved surface (2) and which are positioned so as overlap with the positions to be rotated and are synchronized with one another, is opened and closed by a single rotating knob (11) and is synchronized with the other petal-shaped parts (1) smoothly and effectively to replicate the movement of a flower opening and closing.

主权项

1. An accessory/decoration, comprising:
a lower group of a plurality of operation bases arranged in a rotationally symmetric positions; and an upper group of a plurality of petal shaped parts, wherein the operation bases are connected with the petal shaped parts respectively, the operation bases form a spherical surface, each of the operation bases is overlapped with the neighboring operation base at an end portion in the arranged direction of the operation bases to form a rotary opening/closing mechanism, rotation shafts are provided at each of connecting portions between the operation bases and petal shaped parts to be directed in a horizontal tangential direction of the spherical surface, the operation bases have the same shape with each other, and the operation bases are rotatable in a predetermined range around the rotation shaft.
