Abstract (en)
[origin: WO8704920A1] A support foot for stick-like walking aids, such as crutches, comprises a support tube connected to an adapting portion coupled by means of a pivotable and rotary joint with a bearing arrangement for a sole body. The joint is integrated in the support foot and is elastic at least in the supporting direction, preferably also in the rotational direction. The joint is preferably comprised of a connection body having embedded in its elastic mass more rigid elements intended to transmit the bearing force from the sole body to the support tube. The support foot is thus comprised of very few elements, is silent and preserves all the supporting apparatus of the handicapped since the peaks in the load curve of the support foot are efficiently eliminated.
