Title:
LINEAR MOTION EXPANSION AND CONTRACTION MECHANISM, AND ROBOT ARM MECHANISM WITH THE SAME
Document Type and Number:
Japanese Patent JP2018071704
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce a weight of an arm part while suppressing strength degradation in a linear motion expansion and contraction mechanism.SOLUTION: A linear motion expansion and contraction mechanism comprises: a plurality of first segments 53 connected to one another at front and rear ends in a bendable manner; a plurality of second segments 54 connected to one another in a bendable manner at front and rear ends of bottom plates; a connection part 55 connecting a headmost first segment and a headmost second segment; and a support part 25 that supports the first and second segments movably in a front-back direction, joins the first and second segments to one another when the first and second segments move forward and separates the first and second segments from one another when the first and second segments move backward. The first and second segments become rigid when the first segments are joined to the second segments, and the first and second segments return to a bending state when they are separated from one another. One or both of the first and second segments gradually decrease in width toward the front.SELECTED DRAWING: Figure 5
