Abstract
Provided is a motion transmission mechanism 30 of a limb motion support device 1A configured so as not to transmit the movements of a pair of braces 10R and 10L attached to right and left legs to spring members 20R and 20L in a state where the bending degrees of the right and left legs are smaller than a predetermined bending degree in the case where both of the right and left legs equipped with the braces 10L and 10R are bent from a stretched state and configured to transmit the movements of the braces 10L and 10R to the spring members 20L and 20R via a wire 31 after the bending degrees of the legs increase to be larger than the predetermined bending degree.
Claims37
A limb motion support device comprising:
- a pair of braces adapted to be attached to the right and left limbs of a user, respectively;
- one or more spring members that generate elastic forces for assisting a bending and stretching motion of the right and left limbs by an elastic deformation, and are shared between the right and left limbs;
- and
- a motion transmission mechanism that transmits a motion between the pair of braces and the spring member so as to elastically deform the spring member by transmitting movements of the pair of braces associated with the bending and stretching motion of the right and left limbs to the spring member,
- wherein the motion transmission mechanism is configured not to transmit the movements of the pair of braces to the spring member in a state where bending degrees of the right and left limbs are smaller than a predetermined first bending degree, in a case where both of the right and left limbs equipped with the pair of braces are bent from a stretched state, but configured to transmit the movements of the pair of braces to the spring member after increasing the bending degrees of the right and left limbs to a bending degree larger than the first bending degree.
