For a prosthetic leg in which the ankle joint moves slightly in the upward and downward direction, the lower base body placed on the foot side and the joint shaft of the upper body part of the joint placed on the lower leg pipe side are connected by a hinge, and the lower end is attached to the upper body part of the joint. The foot joint passes through a regulating shaft that is attached to the lower body part, and a dorsiflexion bumper is attached to the upper part of the regulating shaft, and the plantarflexion bumper is interposed between the upper body part of the joint and the lower body part, so that the foot joint is normal (contact). There is one (Special Publication No. 57-65 of 1983) that was restored to a horizontal position (ground level).
ところで履物を履く際や坐る際、或は踵の高い
靴を履いたり坂道をのぼりおりする際の足首の俯
仰角度は特に大とする必要がある。 Incidentally, when putting on footwear, sitting, wearing high-heeled shoes, or climbing up or down a slope, the angle of elevation of the ankle needs to be particularly large.

又希望の俯仰角度に固定するには楔ヘを打ち込ん
でいる。 As shown in Figure 4, a prosthetic leg that can increase the angle of elevation of the ankle is shown in Figure 4, where the lower leg (A) and foot (B) are connected at a joint (C), and the gap (D) formed at the joint is filled with a soft material. An elastic piece is interposed and fixed so that even if the angle of elevation is changed, it will return to the normal position.
Also, to fix the desired elevation angle, a wedge is driven in.

に倒すと減速モーターは正回転して足部が俯角に
変化し、同つまみを中立位にすると減速モーター
が停止してその俯仰角度に固定される。
When you turn the switch knob to one side, the deceleration motor rotates forward and the foot changes to the elevation angle, and when you turn the same knob to the other side, the deceleration motor rotates forward and the foot changes to the depression angle, and the same knob returns to the neutral position. The deceleration motor then stops and the elevation is fixed at that angle.
