Glove-type power assist device

Abstract

Provided is a glove-type power assist device which has no uncomfortable feeling when in use, is easy to put on, and convenient to use in daily life. The glove-type power assist device of the present invention comprises: a glove (10) which comprises a finger insertion portion (11); an elastic tube (20) fixed on a dorsal side of the finger insertion portion (11) and restricted in stretching along a longitudinal direction on the side; and a fluid supply medium supplying a fluid to the elastic tube (20). The glove-type power assist device supports a bending movement of a finger by supplying the fluid to the elastic tube (20), stretching the dorsal side more than a ventral side of the elastic tube (20), and bending the elastic tube (20) toward the ventral side. Actually the whole of the glove (10) is formed of an elastic base material (13) which has elasticity, and a side line (L1) forming a boundary between the dorsal and ventral sides of the finger insertion portion (11) has an inelastic structure restricting the bending toward the longitudinal direction of the finger insertion portion (11) so that the elastic tube (20) is bent centering around a bending point of a joint of the finger.

Description

technical field [0001] The present invention relates to a glove-type power assist device that assists the finger movements of a wearer by being worn on the hand. Background technique [0002] With the development of fewer children and aging, the shortage of nursing staff has become a more serious problem, and more and more so-called old-old nursing phenomena of the elderly caring for the elderly are seen. Therefore, there is an increasing demand for power assist devices aimed at reducing the physical burden on caregivers and helping care receivers to stand on their own. Various assisting devices have been proposed corresponding to the parts to be assisted, and glove-type assisting devices for assisting bending motion of fingers are also known. [0003] For example, Patent Document 1 describes a power-assisted glove (glove-type power-assisted device) that has a hose-shaped actuator that bends when the internal pressure increases when a fluid is supplied, and in order to make...

AI Technical Summary

Problems solved by technology

However, in the glove-type power booster of Patent Document 1, although the bending center of the actuator coincides with the bending center of the finger joints, when the actuator is deformed, it has to pass through the bending center of the actuator and gradually The bending center of the joint is close to such a process, so it is impossible to completely remove the dissonance felt near the joints of the wearer's fingers at this time

In addition, the glove-type booster in Patent Document 1 is not necessarily a device that is easy to miniaturize and carry
