20140020507 | SCOTT RUSSELL MECHANISM DEVICE - A tip end part of a main arm member of a Scott Russell mechanism is enabled to be brought close to a base end part of a sub arm member. A Scott Russell mechanism device is formed into a boomerang-like shape such that a main arm member coupled to a sub arm member is curved to detour a coupling position. Thus, when the coupling angle is changed so that a base end part of the main arm member and a base end part of the sub arm member are most separated from each other, a tip end part of the main arm member can be moved close to right beside the base end part of the sub arm member. With the Scott Russell mechanism device, a moving range of the tip end side of the main arm member can be enlarged. | 01-23-2014 |
20140026705 | SCOTT RUSSELL MECHANISM DEVICE - A joint unit pivotably coupled to a tip end part of a main arm member of a Scott Russell mechanism is pivoted in two ways. A Scott Russell mechanism device pivotably couples a main arm member and a sub arm member to each other, as well as it pivotably couples a joint unit to a tip end part of the main arm member. Moreover, by providing a pivot driving unit to the main arm member, as well as providing a fourth motor and a drive transmission mechanism unit to the sub arm member, the Scott Russell mechanism device can switch between pivoting the joint unit associatively a change of a coupling angle of the arm members and and pivoting the joint unit by the drive of the fourth motor. | 01-30-2014 |
