LINEARLY MOVING EXTENDABLE MECHANISM AND ROBOT ARM EQUIPPED WITH LINEARLY MOVING EXTENDABLE MECHANISM

Document Type and Number:

WIPO Patent Application WO/2010/070915

Kind Code:

A1

Abstract:

A linearly moving extendable mechanism includes a plurality of block bodies (22) and can attain extension of a linearly moving joint (J3) by mutually coupling and rigidifying the block bodies (22), whereby a desired arm length can be provided. When the block bodies (22) are individually separated from the arrangement of the rigidified block bodies (22), contraction of the linearly moving extendable telescopic joint (J3) is attained. Although the block bodies (22) released from rigidified state are arranged in series, the blocks are not firmly coupled and are capable of bending in any direction, whereby the block bodies (22) can be received compactly in a support body (1). Consequently, a linearly moving extendable mechanism, which may have an enhanced safety while eliminating the inevitable risk in a typical robot arm having an elbow joint such that when the elbow joint is closed, things therearound are clasped, and which may have a reduced occupation space, can be provided.
