摘要： A walking assistance device has a drive mechanism, which is provided with a linear-motion actuator including an electric motor installed in the upper link member, nut members which are rotationally driven by the electric motor, and a linear-motion output shaft which linearly moves in the direction of the axial centers of the nut members, and a crank arm which is secured to the lower link member coaxially with a joint axis of a third joint and swingably attached to one end of the linear-motion output shaft. The drive mechanism is constructed such that a translational force output from the linear-motion output shaft of the linear-motion actuator is converted into a rotational driving force of the third joint through the crank arm.

摘要： A walking aid apparatus comprising a sitting member which a user sits astride and leg links each coupled to a connection provided on the undersurface of the sitting member in such a way as to be free to swing in the forward/backward direction, which improves the stability of the sitting member. The connection is adapted in such a way that a forward/backward swinging fulcrum of the leg links is located above the sitting member. More specifically, the connection is provided with an arc-shaped guide track longitudinal in the forward/backward direction and having the center of curvature above the sitting member, so that each of the leg links swings along the guide track in the forward/backward direction. If the leg links are allowed to swing freely also in the lateral direction, preferably the lateral swinging fulcrum of the leg links is also located above the sitting member.

摘要： In a walking assist device having leg links each connected to a support member through a first joint and having a first link and second link connected to the first link through a second joint, and actuators to be operated to displace the first and second links relative to each other to produce assist forces that assist part of user's body weight to assist the user to walk, it is configured such that a forward protruding amount of the second joint to be protruded with change of an angle between the first and second links about the second joint is changed. With this, it becomes possible to decrease the forward protruding amount to be protruded from the trunk of the user with change of the angle about the second joint, thereby decreasing the inertia force about the vertical axis, while mitigating the unnatural impression of the appearance.

摘要： A walking assisting device having leg links connected to a load transfer portion, wherein each leg link is free to bend and stretch at a joint in the middle of the leg link, the leg link being formed to a length such that the joint projects forward of a reference line when a user is standing upright. The reference line is a line connecting a swing fulcrum of the leg link to a joint at the lower end of the leg link. Stability is improved by diminishing a moment in a forward tilting direction when the user is standing upright. The leg links are provided with an overhanging portion and a driving source mounted on the overhanging portion, which helps maintain balance relative to the reference line. The driving force is transmitted to the joint in the middle of the leg link via driving force transmission means.

摘要： A walking assistance device having a leg link connected to a load transfer portion via a first joint and to a foot attachment portion via a second joint, and having an intermediate third joint moving such that a distance between the first joint and the second joint is variable; a drive source for the third joint; and a battery for the drive source. When in an upstanding position, force in the forward-backward direction is prevented from acting on the load transfer portion to enhance stability. Also, a moment of inertia of the leg link is decreased to curtail a load applied to the leg of the user. The drive source and the battery are located at positions higher than the third joint, and when the user is in an upstanding position, a plane passing through the second joint lies between the drive source and the battery.

摘要： A walk assistance device capable of transmitting a force generated by a leg link to a user's trunk via a load transmit portion, wherein the leg link includes an upper first link portion connected to the load transmit portion via a first joint portion, a lower second link portion connected to a foot attachment portion via a second joint portion, a middle third joint portion connecting the first link portion to the second link portion such that a distance between the first joint portion and the second joint portion is variable, and a driving source that drives the third joint portion. The moment of inertia around the first joint portion of the leg link is reduced to decrease a load on the user's leg in walking. The driving source is disposed above the third joint portion of the first link portion so that the center-of-gravity of the entire leg link is located above the third joint portion. In the case where the driving source includes an electric motor and a reduction gear, the electric motor is disposed above the reduction gear.
