Abstract

Ujawniony jest mechanizm przesuwania osi obrotu wymachu kończyny zawierający część górną egzoszkieletu (1) i część dolną egzoszkieletu (2), charakteryzujący się tym, że dolna część egzoszkieletu (2) połączona jest z dolną częścią (6b) przegubu poprzez przegub wymachu (9), przy czym dolna część (6b) przegubu połączona jest z górną częścią (6a) przegubu poprzez połączenie wahadłowe (6), przy czym część górna (6a) przegubu połączona jest z częścią górną egzoszkieletu (1) poprzez co najmniej jedną prowadnicę (3, 3a), również pomiędzy częścią górną egzoszkieletu (1), a częścią górną (6a) przegubu umieszczony jest pierwszy mechanizm dźwigniowy (4), przy czym pierwszy mechanizm dźwigniowy (4) zawiera na jednym końcu zamocowany pierwszy element hydrauliczny (22) natomiast drugi koniec pierwszego elementu hydraulicznego (22) dołączony jest do górnej części (6a) przegubu, przy czym drugi element hydrauliczny (23) dołączony jest z jednej strony do wspornika (21) drugiego elementu hydraulicznego (23), przy czym wspornik (21) dołączony jest z drugiej strony do górnej części (6)a przegubu, natomiast z drugiej strony drugi element hydrauliczny (23) dołączony jest do mechanizmu dźwigniowego (24) połączonego drugim końcem z dolną częścią (6b) przegubu, przy czym komora (5) pierwszego elementu hydraulicznego (22) połączona jest z komorą (7) drugiego elementu hydraulicznego (23) poprzez pierwszy przewód hydrauliczny (8a) i drugi przewód hydrauliczny (8b).A mechanism for shifting the axis of rotation of a limb swing is disclosed, comprising an upper part of an exoskeleton (1) and a lower part of an exoskeleton (2), characterized in that the lower part of the exoskeleton (2) is connected to the lower part (6b) of the joint via a swing joint (9), wherein the lower part (6b) of the joint is connected to the upper part (6a) of the joint via a pendulum connection (6), wherein the upper part (6a) of the joint is connected to the upper part of the exoskeleton (1) via at least one guide (3, 3a), also between the upper part of the exoskeleton (1) and the upper part (6a) of the joint a first lever mechanism (4) is arranged, wherein the first lever mechanism (4) comprises a first hydraulic element (22) attached at one end, while the second end of the first hydraulic element (22) is attached to the upper part (6a) of the joint, wherein the second hydraulic element (23) is attached at one end on one side to a support (21) of a second hydraulic element (23), wherein the support (21) is connected on the other side to the upper part (6)a of the joint, and on the other side the second hydraulic element (23) is connected to a lever mechanism (24) connected at its other end to the lower part (6b) of the joint, wherein the chamber (5) of the first hydraulic element (22) is connected to the chamber (7) of the second hydraulic element (23) via a first hydraulic line (8a) and a second hydraulic line (8b).
