Embodiment Construction

[0017] Next, a walking assistance device according to an embodiment of the present invention will be described. Figure 1 and figure 2 As shown, the walking assisting device has a seat member 1, which is a load transmission part into which a user P steps and sits, a pair of left and right foot plate equipment parts 2, 2 equipped on the left and right foot plates of the user, and a pair of left and right leg connecting parts. Rods 5, 5, the left and right pair of leg connecting rods 5, 5 are connected to the seat member 1 through the first joint part 3 at the upper end, and are connected to the two-foot board equipment part 2, respectively through the second joint part 4 at the lower end. 2 on.

[0018] Each leg link 5 is composed of a link that can change the distance between the first joint part 3 and the second joint part 4 and can flexibly extend. That is, each leg link 5 is formed by flexibly connecting the upper first link part 6 and the lower second link part 7 through ...

Abstract

A walk assistance device capable of transmitting a force generated by a leg link to a user's trunk via a load transfer portion, wherein the leg link includes an upper first link portion connected to the load transfer 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.

Description

technical field [0001] The invention relates to a walking assisting device for assisting a user in walking. Background technique [0002] Hitherto, such a walking assisting device has been known, that is, it has: a trunk equipment part, which is equipped on the user's torso; to the trunk outfit part, and equipped on the thigh of the user's leg; the lower leg outfit part, which is connected to the thigh outfit part through the knee joint part corresponding to the human knee joint, and equipped on the lower leg of the user's leg; and The footboard equipment part is connected to the calf equipment part through the ankle joint part corresponding to the human ankle joint, and is equipped on the user's footboard; source (for example, refer to Japanese Patent Laid-Open No. 2003-220102). In this walking assist device, the user's thigh is given assist torque from the driving source for the hip joint through the thigh armament, and at the same time, the assist torque from the drive ...
