Title:
LINEAR EXTENSION/RETRACTION MECHANISM AND ROBOT ARM MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/052143
Kind Code:
A1
Abstract:
In order to avoid a reduction in strength while reducing the weight of an arm unit in a linear extension/retraction mechanism, this linear extension/retraction mechanism is equipped with: multiple first pieces 53 coupled to each other so as to be capable of bending at the front and back ends; multiple second pieces 54 coupled to each other so as to be capable of bending at the front and back ends of a base plate; a coupling unit 55 for coupling the heads of the first pieces and the heads of the second pieces; and a support unit 25 supporting the first and second pieces so as to be capable of moving forward and backward. When the first and second pieces are moved forward they overlap each other and form a columnar body, and when the first and second pieces are moved backward they separate from each other and return to the bent state. The first pieces and the second pieces have a different width.
