Title:
EXTENDING AND RETRACTING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/097814
Kind Code:
A1
Abstract:
[Problem] To propose an extending and retracting mechanism with which it is possible to improve spatial efficiency when extending and retracting operations are performed. [Solution] This extending and retracting mechanism is provided with at least three link structures which are each configured by sequentially coupling ends of a plurality of link members to one another in such a way as to be capable of mutual rotation, and which extend and retract parallel to one another as a result of a change in an angle between the link members that are coupled to one another, and a plurality of connecting members which are coupled to each of the at least three link structures, wherein the plurality of connecting members include a first connecting member on which a main body portion of an actuator is installed, and a second connecting member coupled to an output shaft of the actuator, and wherein, in accordance with the driving of the actuator, the second connecting member moves in a prescribed extending and retracting direction which is parallel to a direction in which the at least three link structures extend and retract.
