    Abstract: A prosthesis includes a knee joint having movable elements geared together and rotatable about axes located rearward of a vertical bearing axis of the prosthesis. A foot member is pivoted about a horizontal ankle joint and is urged by a first spring toward the toe-down position and by a second spring toward the toe-up position. The first spring is stronger than the second spring. A tie rod is connected from the knee joint to the first spring to reduce the force applied by the first spring so that, when the knee joint is bent and the foot is raised from the ground to move the prosthesis forward to a straight-knee position, the toe of the foot is raised to clear the ground. The axis of the knee, being in a position aft of the vertical axis, tends to stably support the leg when it is in its weight-bearing position.

    Abstract: The knee pivot or hinge shaft of the artificial limb connecting the upper limb portion and the lower portion is located forward of the center line of gravity in the prosthesis whereby the arc of the foot of the limb is shortened as the foot moves rearwardly from a straightened position of the limb. The knee joint is provided with a locking mechanism which is actuated to lock the upper limb portion to the lower limb portion either by downward pressure applied to the upper limb portion as the artificial limb rests on a support surface or by pressure applied to the heel portion of the foot as it engages a support surface. The actuating lever of the locking mechanism pivots about a first fulcrum to actuate the locking mechanism as pressure is initially applied to the heel of the foot during the amputees stride and, as the weight of the amputee is transferred from the heel to the ball or toe portion of the foot, the actuating lever pivots about a second fulcrum. The locking mechanism remains in the actuated or locked condition as the lock actuating lever moves from one fulcrum to the other.

    Abstract: An artificial leg includes a trunk socket, a thigh section hingedly coupled to the trunk socket, a leg section hingedly coupled to the thigh section and a foot section hingedly coupled to the leg section. A mechanical energy storage device, such as a spring, is operatively associated with the artificial leg for storage and release of energy during a normal walking stride of the user. More particularly, energy is stored in the mechanical energy storage device during a weight-bearing phase of the walking stride when the user's weight is on the artificial leg and energy is released during a phase of the normal walking stride, when the user's weight is removed from the artificial leg. The stored energy is released from the energy storage device to pivot the thigh section forwardly about the hinged coupling thereof to the trunk socket. A dash-pot is coupled between the lower end of the thigh section and the foot section for damping flexion of the knee joint after a certain predetermined extent of ankle flexion is achieved to derive a more normal stride and cadence.
