Problems solved by technology

[0004] In the above-mentioned conventional walking assisting device (exercise assisting device), the foot support is connected to the foot link portion in such a manner that the ankle joint can perform only plantar / dorsiflexion, and therefore, when the ankle joint undergoes pronation / supination, the foot support Unable to follow the motion, causing discomfort to the user
[0005] In addition, the plantar / dorsiflexion of the ankle joint requires a large force to maintain body balance. Therefore, for traditional sports assisting devices, when pronation / supination and plantar / dorsiflexion occur at the same time, the user often suffers. to great discomfort

Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038] First, refer to Figure 1A , 1B , 2A and 2B depict a human ankle joint 1 . Figure 1A A rear view of the right foot is shown, Figure 1B A top view of the right foot is shown, Figure 2A shows a medial view of the right foot, and Figure 2B A top view of the right foot is shown. The ankle joint 1 includes a talar calf joint 5 composed of the tibia 2 , fibula 3 , and talus 4 , and a subtalar joint 7 composed of the talus 4 and the calcaneus 6 . The primary function of the talocrural joint 5 is to allow ankle 1 plantar / dorsiflexion, while the primary function of the subtalar joint 7 is to allow ankle 1 pronation / supination.

[0039] Here, refer to image 3 , to determine the reference plane of foot 8. In the base limb position (the base limb position is the limb position of the static upright posture, wherein the longitudina...

Abstract

The present invention provides an ankle joint mechanism to be assembled on the user's ankle to assist the user's body movement, which includes: a lower leg link to be arranged along the user's lower leg; a foot stand; a plantar / dorsiflexion mechanism configured to connect said calf link and said foot stand to each other to be pivotable about a plantar / dorsiflexion axis of a user's ankle; an adduction / abduction mechanism configured to connect the calf link and the kickstand mount to each other to pivot about the adduction / abduction axis of the ankle joint; and varus / abduction A varus / valgus mechanism configured to connect the calf link and the kickstand mount to each other to be pivotable about a varus / valgus axis of the ankle joint.

Description

technical field [0001] The invention relates to an ankle joint mechanism assembled on a user's ankle to assist the user's body movement. Background technique [0002] The walking assist device disclosed in JP2015-181661A includes: a foot support on which a user's foot is placed; a foot link connected to the foot support so as to be arranged on the lateral side of the foot; and a lower leg link , the calf link configured to be disposed along the user's calf. The foot link and the lower leg link are connected to each other by engagement of their mutually facing uneven surfaces, and are fastened to each other by screws. The uneven surfaces of the foot links and calf links each have parallel ridges and grooves extending in the front-to-rear direction, so that the uneven surfaces can engage each other at various vertically relative positions, and their relative front-to-back positions vary in engagement. It can then be adjusted by sliding along the ridges and grooves. Thereby,...
