  • Linear-motion telescopic mechanism and robot arm having linear-motion telescopic mechanism
    Patent number: 8925405
    Abstract: A linear-motion telescopic mechanism according to the present invention includes a plurality of block members (22) by which an arbitrary arm length is achieved in such a manner that the plurality of block member (22) are rigidly connected to each other so as to elongate a linear-motion telescopic joint (J3). On the other hand, by separating the plurality of block members (22) one by one from a rigid alignment of the plurality of block members (22), the linear-motion telescopic joint (J3) is contracted. The block members (22) unfixed from the rigid alignment are still serially connected but not in a rigid manner. That is, the block members (22) thus unfixed can be flexed in any directions, and therefore can be housed inside a support member (1) in a compact manner.
