Joints for Prosthetic, Orthotic and/or Robotic Devices
First Claim
1. An artificial foot device, comprising:
- a toe pivotably coupled with a core at a joint;
a vertical restraint link extending across the joint that couples the toe with the core;
wherein the vertical restraint link limits motion of the toe in a vertical direction relative to the core.

Abstract
An artificial foot device may include a talus body, a core operatively coupled with the talus body by a first joint, and a toe operatively coupled with the core by a second joint. A vertical restraint link between the toe and the core and provides a coupling for the second joint. A toe insert limits motion of the toe relative to the core. A toe bushing receives a tension member for operatively coupling the toe to the talus body. The vertical restraint link, toe insert and bushing constrains relative movement between the core and the toe at the second joint. Relative movement of the core and the talus body at the first joint is guided and constrained by pivot bearings. Constrained relative movement between the talus body and the core corresponds to a coordinated movement of a first joint and a second joint during ambulation of a natural human foot.

13. An artificial foot device, comprising:
-
a talus body; a core pivotably coupled with the talus body at a first joint; and a biasing assembly acting between the talus and the core at the first joint; wherein the talus body pivots about the first joint and causes the biasing assembly to provide a torque response for the artificial foot device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
