BLADE FOR WIND SPINNING TOP
Document Type and Number:
Japanese Patent JP2012040333
Kind Code:
A
Abstract:

To provide a wind spinning top spinning more smoothly than a conventional one, and further spinning longer.

The wind spinning top uses a blade having a horizontal cross-section of L-shape or arcuate shape. For example, as shown in Fig.1, the wind spinning top 1 is formed such that a spinning body 2 includes a disc-shaped spinning body 2, a cylindrical spindle 4, and a cylindrical spinning shaft 5 having a round pointed lower tip, the spinning body has an upper surface mounted with four blades 3 having an L-shaped horizontal cross-section. When the spinning top 1 is spun by the wind of breath, the spinning top is spun smoothly, stably, and longer compared with a spinning top mounted with blades having a linear horizontal cross-section.
