Abstract
A prosthetic foot is characterized by an attachment section and plurality of curvilinear foot portions extending downwardly from the attachment section to contact a supporting surface. The portions are capable of movement independent from one another. Preferably, the plurality of foot portions is fabricated by dividing a forefoot portion and a heel portion demountably attached thereto. Such division may be achieved by the provision of a slot in said forefoot and heel portions. A strap or similar expedient is provided to limit the movement of the foot portions relative to each other.
Claims20
In a prosthetic foot, the combination of:
- attachment means for facilitating the operative engagement of the foot with a wearer's stump;
- and a plurality of curvilinear, energy-storing foot portions operatively attached to said attachment means and extending downwardly therefrom to contact a supporting surface, each of said foot portions including an ankle section, whereby said foot portions may interact with the supporting surface independently from one another, in which said plurality of curvilinear portions are of similar shape.
A prosthetic foot including:
- a forefoot portion incorporating an upper attachment section for facilitating operative connection to a wearer's stump, a curvilinear ankle section, an arch section and a toe section;
- and a heel portion having an attachment section secured to said forefoot portion and a heel section extending therefrom, in which said forefoot and heel portions are completely or partially divided into similarly-shaped segments capable of movement relative to one another.
In a prosthetic foot, the combination of, attachment means for facilitating the operative engagement of the foot with a wearer's stump;
- and a bifurcated, curvilinear, energy-storing foot portion operatively attached to said attachment means and extending downwardly therefrom to contact a supporting surface, said bifurcation of said foot portion extending in an anterior/posterior direction with respect to the wearer and including substantially all of said foot portion, whereby the resulting bifurcated sections of said foot portion may interact with the supporting surface independently from one another.
