Title
(EN) QUICK-RELEASE COUPLER FOR FOOT PROSTHESES
(FR) CONNECTEUR RAPIDE POUR PROTHESES DE PIED
Abstract
(EN)
A quick-release coupler (24) is adapted to couple a foot prosthesis (26) to a substantially vertical stump-supporting cylindrical pylon (22). The coupler comprises an attachment frame member (28) and a compression wedge assembly (32). The attachment frame member (28) is adapted to be attached to an upper substantially vertical surface (30) of a prosthetic foot member (26), and to receive the pylon and compression wedge assembly. The compression wedge assembly includes a clamping bolt (54) and two compression blocks (50, 52) adapted to be clamped together and to apply a compression force against the pylon (22). The compression force secures the pylon (22) within the attachment frame member (28). An optional alignment wedge (66) is adapted to be secured between the quick-release coupler (24) and the upper vertical surface of the prosthetic foot (26), and to thus provide an angular displacement between the pylon and the foot. Thus, the present invention advantageously permits quick and convenient attachment and detachment of prosthetic feet to vertical cylindrical pylons, as well as the combined use of forward- or backward-leaning foot members with substantially vertical stump-supporting pylons.
(FR)
L'invention concerne un connecteur rapide (24) conçu pour connecter une prothèse de pied (26) à un pilon (22) cylindrique supportant un moignon sensiblement vertical. Le connecteur comporte un élément de structure de fixation (28) et un ensemble cale de compression (32). L'élément de structure de fixation (28) est conçu pour être fixé à une surface supérieure (30) sensiblement verticale d'un élément de pied artificiel (26), et pour recevoir le pilon et l'ensemble cale de compression. L'ensemble cale de compression comporte un boulon de serrage (54) et deux blocs de compression (50, 52) conçus pour être serrés et pour appliquer une force de compression contre le pilon (22). La force de compression fixe le pilon (22) à l'intérieur de l'élément de structure de fixation (28). Une cale d'alignement (66) facultative est conçue pour être fixée entre le connecteur rapide (24) et la surface verticale supérieure du pied artificiel (26), et permettre ainsi un déplacement angulaire entre le pilon et le pied. Par conséquent, la présente invention permet avantageusement de fixer le pied artificiel à des pilons cylindriques verticaux et de le détacher de ceux-ci de façon rapide et pratique, et de combiner des éléments de pied s'appuyant vers l'avant ou vers l'arrière à des pilons supportant un moignon sensiblement vertical.
