More Information
Summary:There are provided an artificial joint device that can realize an artificial limb enabling twisting motion without a drive source, and when with the drive source, reduce the size and costs of the device, and a parallel linkage that can realize the device. The linkage connects a foot portion and a mounting plate spaced from each other. A fixed link has one end fixed to the plate, and the other end connected to the foot portion via a ball joint, making the angle of the fixed link relative to the foot portion changeable in any direction. Expansible links extend between the foot portion and the plate in an expansible/contractible manner and each have opposite ends connected to the plate and the foot portion via respective upper and lower ball joints, making respective angles thereof relative to the foot portion and the plate changeable in any direction.
