20090312844 | CONTROL DEVICE FOR WALKING ASSIST DEVICE - A control system for a walking assist device includes a ground detecting means having a plurality of force sensors equipped to each foot attachment portion. Each ground sensor selectively outputs a ground state output and non-ground state output in accordance with whether the foot attachment portion is grounded at a position immediately below the ground sensor. The control system is equipped with a means that continuously generate preference data for each of the ground detecting means, where the reference data increases and decreases in value in accordance with the change of a total number of the ground sensors generating ground state output in the ground detecting means. Also, a means that determines a mutual desired proportion of the supporting force to be applied to the both leg links from the floor side is provided. | 12-17-2009 |
20100113989 | WALKING ASSISTANCE DEVICE - A walking assistance device has a drive mechanism for driving a third joint of a leg link of the walking assistance device, the drive mechanism including a crank arm secured to a lower link member and a linear-motion actuator which has a linear-motion output shaft connected to the crank arm. The angle formed by a straight line connecting a joint axis of the third joint and a connecting portion of the linear-motion output shaft relative to the crank arm and a straight line which passes the connecting portion and which is parallel to the axial center of the linear-motion output shaft changes from an angle closer to the straight angle toward an angle closer to the right angle as the flexion degree of the leg link is increased from a flexion degree corresponding to a state wherein a user is in an upright posture. | 05-06-2010 |
20100152630 | WALKING ASSISTANCE DEVICE AND CONTROLLER FOR THE SAME - A walking assistance device is capable of preventing a load transmit portion thereof from falling due to gravity when the operation of an actuator of the walking assistance device is stopped. A leg link is provided with an elastic member that imparts, to a third joint, an urging torque for restraining the flexion degree of the leg link from changing from a predetermined first flexion degree due to the gravity acting on the walking assistance device in a reference state wherein a foot-worn portion connected to the load transmit portion through the leg link is in contact with a ground and the flexion degree of the leg link the third joint is the first flexion degree. | 06-17-2010 |

20090237025 | BIPEDAL WALKING ROBOT - Provided is a bipedal walking robot which includes a linear actuator, which connects a crus link and a foot of each leg away from an ankle joint, for driving the foot to rock around the ankle joint with respect to the crus link according to a telescopic motion thereof. The robot is capable of applying a desired moment to the foot for walking on stairs without increasing the linear actuator in size. The linear actuator is disposed in such a way that a telescopic force therefrom acts on a line inclined backward with respect to a connection line connecting a knee joint and the ankle joint. Preferably, a connection portion, which is connected to the crus link, of the linear actuator is disposed backward from the connection line, and a connection portion, which is connected to the foot, of the linear actuator is disposed forward from the connection line. | 09-24-2009 |
20090292232 | WALKING ASSIST DEVICE - Provided is a walking assist device including a seat member, a leg link having a joint portion, and a driving source for the joint portion. The walking assist device allows a user to rest by sitting on the seat member. Accordingly, the walking assist device further includes a lock mechanism disposed in the joint portion and an operation unit for the lock mechanism. When the operation unit is switched on, the driving source is controlled to increase an up-pushing force on the seat member. A variation rate on the up-pushing force is increased with time to a given value where the lock mechanism is initiated. | 11-26-2009 |
20110306907 | WALKING ASSIST DEVICE - 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. | 12-15-2011 |
