Abstract
An orthotic device for a human body joint at which a body appendage pivots includes a first member extending along the appendage on a first side of the joint, a second member extending along the appendage on a second side of the joint opposite the first side, a connection joining the first member and the second member and having an axis about which the members articulate, a cuff spaced from the axis, and a mechanism displacing the cuff along one of the members in response to articulating the device at the connection.
Claims22
An orthotic device for a joint of a human body at which a body appendage pivots, comprising:
- a first member located on a first side of the joint;
- a second member located on a second side of the joint opposite the first side;
- a connection joining the first member and the second member and having an oriented axis about which the members pivot toward a flexion position and extended position;
- a cuff spaced from the axis;
- and
- a mechanism having an actuator for displacing the cuff along one of the members while moving toward the flexion or extended position in response to pivoting the device at the connection.
An orthotic device for a joint of a human body at which a body appendage pivots, comprising:
- a first member located on a first side of the joint;
- a second member located on a second side of the joint opposite the first side;
- a connection joining the first member and the second member and having an axis about which the members pivot;
- a first cuff spaced from the axis;
- a second cuff spaced from the axis;
- a first mechanism for displacing the first cuff along the first member in response to the device pivoting at the connection;
- and
- a second mechanism for displacing the second cuff along the second member relative to the axis in response to the device pivoting at the connection.
An orthotic device for a joint of a human body at which a body appendage pivots, comprising:
- a first member located on a first side of the joint;
- a second member located on a second side of the joint opposite the first side;
- a connection joining the first member and the second member and having an axis about which the members pivot;
- a cuff spaced from the axis;
- a strap that flexes as the device pivots including a portion that moves through a displacement along the first member relative to the axis in response to said flexure;
- and
- a mechanism engaged with the strap portion and the cuff, actuated by said displacement, and moving the cuff through a distance greater than the displacement.
