Title:
SPHERICAL BODY DRIVE TYPE MOVEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/110651
Kind Code:
A1
Abstract:
A spherical body drive type movement device 10 moves on a traveling surface G and is provided with rotary bodies 14, 15, 16 that, while being in contact with n-number of drive spherical bodies 11, 12, 13 from two different directions, rotatably drive the drive spherical bodies 11, 12, 13. When the traveling surface G is defined as a horizontal surface, centers P1, P2, P3 of the drive spherical bodies 11, 12, 13 are located on lateral edges S1, S2, S3 of a virtual inverted n-gonal pyramid H having a bottom surface η provided at a position higher than those of the centers P1, P2, P3 of the drive spherical bodies 11, 12, 13, and having a vertex O away from the bottom surface η disposed at a position lower than those of the centers P1, P2, P3 of the drive spherical bodies 11, 12, 13. The rotary bodies 14, 15, 16 are in contact with the drive spherical bodies 11, 12, 13 at positions higher than those of the centers P1, P2, P3 of the drive spherical bodies 11, 12, 13, and inside the virtual inverted n-gonal pyramid H or on lateral surfaces α, β, γ of the virtual inverted n-gonal pyramid H, and performs rotary drive about rotary shafts 19, 21, 23 perpendicular to the lateral surfaces α, β, γ of the virtual inverted n-gonal pyramid H.
