Title:
LINEAR EXTENSION-RETRACTION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2017/043582
Kind Code:
A1
Abstract:
The present invention joins two types of connecting piece rows that constitute a linear extension-retraction mechanism to enhance the stiffness of the rigid state thereof and achieves smooth deploying and retracting of the connecting piece rows. The linear extension-retraction mechanism is provided with a plurality of first connecting pieces (53) that are flexibly connected together and a plurality of second connecting pieces (54) that are flexibly connected together. The first and second connecting pieces become rigid in a linear fashion when joined together and return to a bent state when separated. The first connecting pieces are each provided with a main body (530). A pair of shaft receiving sections (531) are provided to both sides of the front of the main body. A single shaft receiving section (532) is provided to the center of the rear of the main body. In order to limit bending toward the top surface side from a position in which the connected first connecting pieces are in linear alignment, a protruding section (536) that protrudes rearward is provided to the rear shaft receiving section of the main body, and a receiving section (535) that receives the protruding section is provided between the pair of front shaft receiving sections of the main body.
