PCT No. PCT/DE96/01031 Sec. 371 Date Aug. 26, 1997 Sec. 102(e) Date Aug. 26, 1997 PCT Filed Jun. 5, 1996 PCT Pub. No. WO96/41598 PCT Pub. Date Dec. 27, 1996A foot prosthesis has an inner spring that extends from the heel area to the front area of the foot. The foot spring is enclosed within a cosmetic lining and is joined by a threaded bolt to an adapter with a clamping connection for removably joining the foot prosthesis to a prosthesis tube. The adapter is supported by its lower face, which is designed as a cylinder segment and is provided with serrations, on a joining surface of the inner spring. The joining surface of the inner spring has a shape corresponding to the lower face of the adapter, and has serrations for engaging the adapter's serrations. The upper end of the adapter is designed as a peg which is inserted into the prosthesis tube. The threaded bolt is inserted through a slot that extends in the longitudinal direction of the foot and has a width corresponding to the diameter of the bolt. The lower end of the threaded bolt is supported on the lower side of the inner spring, the lower side being designed as a cylinder segment in the area of the slot. The upper end of the threaded bolt that projects above the adapter peg acts upon the clamping connection such that the spreading element of the clamping connection, which is arranged in a ring-shaped gap between the adapter peg and the prosthesis tube, is actuated when the threaded bolt is tightened. |
