発明の名称 (英語) SPHERICAL BODY DRIVE TYPE MOVEMENT DEVICE NEW
発明の概要(英語) 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.
従来技術、競合技術の概要(英語) BACKGROUND ART
3 Of three spheres and the sphere 3 provide rotational forces to the two driving means (driving motor) (see Patent Document 1) having the mobile device, can be moved in all directions, the electric wheelchair shikidai and free-running of the vehicle or the like is effective to use. The mobile device of the Patent Document 1, two balls 1 on the other hand, each of the driving rotor 2 is rotationally driven by the one of the contact from different directions. In the mobile device, the rotor and the sphere center of the sphere is in contact with the same height position, the idler is pressed against the sphere (the caster wheel-type) of the rotor is provided. And the rotor slips, the mobile device is no longer in a desired direction, a stable running of the mobile device is pressed against the spherical rotor is important to maintain the state.
