Abstract
A wearable chair may include a foot frame configured to support a foot of a user; a shank link configured to rotatably connect to the foot frame; a connecting link provided in front of the shank link and configured to rotatably connect to the foot frame; a knee link configured to rotatably connect to each of the shank link and the connecting link; and a thigh link configured to extend from the knee link. The foot frame, the shank link, the connecting link, and the knee link constitute a four-bar linkage.
Claims11
A wearable chair that is wearable by a user, comprising:
- a first link and a second link integrally formed together as a same piece with the first link extending from a proximal end of the second link at a fixed, oblique incline to the second link so that, when the wearable chair is worn by the user, the first link corresponds to a knee of the user and the second link extends upward from the first link and corresponds to a thigh of the user;
- and
- third and fourth links coupled to the first link and that, when the wearable chair is worn by the user, extend downward from the first link,
- wherein the first link, the second link, the third link and the fourth link operate together so that, as the user moves from a standing position to a sitting position with the wearable chair being worn by the user, the third link rotates forward as an angle between the third link and the first link decreases, the fourth link rotates forward as an angle between the fourth link and the first link decreases, the second link rotates backward, a distal end of the second link is lowered, and the oblique incline remains fixed, so that the wearable chair supports a load of the user in the sitting position.
A wearable chair that is wearable by a user, comprising:
- a first link and a second link integrally formed together as a same piece with the first link extending from a proximal end of the second link at a fixed, oblique incline to the second link so that, when the wearable chair is worn by the user, the first link corresponds to a knee of the user and the second link extends upward from the first link and corresponds to a thigh of the user;
- and
- third and fourth links coupled to the first link and that, when the wearable chair is worn by the user, extend downward from the first link,
- wherein the first link, the second link, the third link and the fourth link operate together so that, as the user moves from a standing position to a sitting position with the wearable chair being worn by the user, the third and fourth links incline forward and the second link inclines backwards, a distal end of the second link is lowered, and the oblique incline remains fixed, so that the wearable chair supports a load of the user in the sitting position.
A wearable chair that is wearable by a user, comprising:
- a first link having a knee portion and a thigh portion integrally formed together as a same piece, with the knee portion extending from a proximal end of the thigh portion at a fixed, oblique incline to the thigh portion so that, when the wearable chair is worn by the user, the knee portion corresponds to a knee of the user and the thigh portion extends upward from the knee portion and corresponds to a thigh of the user;
- and
- second and third links coupled to the knee portion of the first link and that, when the wearable chair is worn by the user, extend downward from the first link,
- wherein the first link, the second link, and the third link operate together so that, as the user moves from a standing position to a sitting position with the wearable chair being worn by the user, the second and third links incline forward and the thigh portion of the first link inclines backwards, a distal end of the thigh portion of the first link is lowered, and the oblique incline remains fixed, so that the wearable chair supports a load of the user in the sitting position.
