  • Patent number: 11147693
    Abstract: The present invention relates to an artificial foot including a foot body part, a toe part rotatably disposed at a first end of the foot body part, a toe joint connecting the foot body part and the toe part to each other, and an adapter disposed on a top of a second end of the foot body part. According to the artificial foot, since the toes of the artificial foot rotate when a wearer walks, when the artificial toes come in contact with the ground, energy is stored due to the load by the weight and the toes kick off the ground as much as the elastic energy accumulated by the spring, so the toe members of the artificial foot do not drag on the ground. Accordingly, the wearer does not need to lift up the hip joints, so the wearer can walk similar to normal walking.
