ROTATION AND EXTENSION/RETRACTION LINK MECHANISM

WIPO Patent Application WO/2005/059407

A1

A rotation and extension/retraction link mechanism realizing a rotation joint having imaginary rotation axes. A rotation and extension/retraction link mechanism (1) is constructed such that a first link (5) having a first imaginary center line (3) and a second link (9) having a second imaginary center line (7) are connected through a rotation and extension/retraction joint mechanism (11). The rotation and extension/retraction joint mechanism (11) is constructed by connecting the first and second links (5, 9) such that, when the second imaginary center line (7) rotates relative to and while crossing the first imaginary center line (3) from a state where the first imaginary center line (3) and the second imaginary center line (7) match to each other, the point where the first imaginary center line (3) and the second imaginary center line (7) cross is displaced on the first imaginary center line (3) by a predetermined distance corresponding to the angle of the rotation.
