ARTIFICIAL FOOT Russian patent published in 2021 - IPC A61F2/66 

FIELD: medicine.

SUBSTANCE: invention relates to artificial feet. Foot comprises an outer shell with a shock-absorbing shaped plate and a support element installed on top of it. Support element is connected with axial hinge and front and rear replaceable shock-absorbers and with adjusting-connecting unit containing two supports with seats for shock absorbers. Shock-absorbing profiled plate from composite material is made with rounded edges. Cross-section of the nose part of the plate represents a base in the form of a rectangle with an upper part in the form of an obtuse-angled triangle with top at the top. Thickness of base is proportional to foot decreasing along longitudinal axis to tip. Obtuse angle of the triangle is proportionally decreasing. Formed smooth tip chamfer of shaped damping plate, which is made in form of inclined cone, base of which forms front upper edge of plate tip, and the vertex coincides with the apex of the obtuse angle of the triangle of the upper part of the section of the plate, wherein the side of the triangle changes into the cone generator.

EFFECT: higher energy efficiency of foot.
