An exoskeleton leg is wearable by a person. The exoskeleton includes a thigh link configured to move in unison with the thigh of the person, a shank link rotatably coupled to the thigh link and comprising at least one tooth, and a locking block coupled to the thigh link and comprising a locking face. Moreover, when the at least one tooth of the shank link contacts with the locking face, the shank link is prevented from flexion motion relative to the thigh link, but is allowed to extend relative to the thigh link.

Exoskeleton legs to reduce fatigue during repetitive and prolonged squatting

A leg support exoskeleton is strapped on as a wearable device to support its user during squatting and/or lunging. The exoskeleton includes a knee joint connected to a first link and a second link, which is configured to allow flexion and extension motion between the first link and the second link. A force generator has a first end that is rotatable connected to the first link. A constraining mechanism is connected to the second link and has at least two operational positions. In a first operational position, the second end of the force generator engages the constraining mechanism, where the first link and the second link flex relative to each other. In a second operational position, the second end of the force generator does not engage the constraining mechanism; the first link and the second link are free to flex and extend relative to each other.
