Title:
JOINT MOVEMENT SUPPORTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/043095
Kind Code:
A1
Abstract:
When an air-pressure adjustment unit supplies air into the bellows (211 to 213) of a finger joint movement supporting unit (110j (j=1,
, 5)), the bellows (211 to 213) are elongated nearly circularly because the annular grooves on the side of the bellows (211 to 213) facing the joints are elastically restrained by elastic members (241 to 243). Therefore, the bellows (211 to 213) cooperatively generate a force in the rotating direction in which the first to third joints extended of the finger are bent. Next, when the air-pressure adjustment unit discharges the air out of the bellows (211 to 213), the bellows are contracted. Therefore, the bellows (211 to 213) cooperatively generate a force in the rotating direction in which the first to third joints bent of the finger are extended. The force generated like this is transmitted to each joint via transmission members (231 to 234). As the results of this, the joint movement supporting device becomes easy to wear and capable of sufficiently supporting the movement of each joint.
