Abstract:
A dynamic platform with extending struts has fastened thereto a bi-directional torsional power unit to selectively deliver force opposing either extension or flexion, and to provide assistance in a respective opposite direction. The power unit is threadably mounted on a hinge pin (spline) centrally located on the platform, and is latched to a catch assembly radially located thereto, the hinge pin of the platform communicating with one end of a torsion spring of the power unit and the catch assembly communicating with another end of the torsion spring, to selectively deliver the extension/flexion force. The power unit can be detached, with simple manual operation of the catch assembly, without tools, flipped over and reattached to the same platform attachment points to switch (reverse) extension torque to flexion torque and vice versa.

Claim (Index 19):
A method of reversing an angular direction of force applied by a hinge assembly for an orthotic, prosthetic or rehabilitative device, where the hinge assembly comprises:\n a first strut and a second strut pivotally attached to one another at a pivot point; a spline extending in a first direction perpendicularly from the first strut and the second strut, at the pivot point, the spline being rotatable relative to one of the first strut and the second strut, where the other of the first strut and the second strut has a catch extending in the first direction, located radially of the pivot point; and a torsion spring having a first end and a second end; the method comprising the steps of:\n attaching the first end of the torsion spring to the extending spline, and attaching the second end of the torsion spring to the extending catch, wherein the torsion spring applies a bias force opposing relative pivotal movement between the first and the second struts in a first of two directions, and aids pivotal movement in a second of the two directions; \n removing the first end of the torsion spring from the extending spline, and removing the second end of the torsion spring from the extending catch; \n flipping the torsion spring over; and \n attaching the first end of the torsion spring to the extending spline, and attaching the second end of the torsion spring to the extending catch, wherein the torsion spring applies a bias force opposing relative pivotal movement between the first and the second struts in the second direction, and aids pivotal movement in the first direction.
