    • The invention relates to a prosthetic device (30), in particular a prosthetic foot for the care of leg amputees. Said device comprises a cardan joint unit (32), which is coupled to a shaft (34) comprising a tread device (40, 42). The cardan joint unit (32) has an articulated element (44), which is rotatably mounted about a first rotational axis (C) and a second rotational axis (D) that deviates from the first. The aim of the invention is to simulate more accurately the natural gait of a healthy human foot. To achieve this, the cardan joint unit (32) comprises an articulated fork (36) on the shaft side that can be coupled to the shaft (34) and an articulated fork (38) on the tread device side that is coupled to the articulated fork (36) on the shaft side by means of the articulated element (44). The articulated fork (36) on the shaft side can be pivoted about the first rotational axis (C) and the articulated fork (38) on the tread device side about the second rotational axis (D) in relation to the articulated element (44). The pivoting displacement of the articulated forks (36, 38) on both sides in relation to the articulated element (44) is carried out in opposition to the resistance of at least one cushioning element that is located in the vicinity of said articulated element.
    • 本发明涉及一种假体装置(30),尤其是假足以供应腿截肢者,包括耦合以铰接,所述万向接头机构(32)和具有性能装置的柄部(34)(40,42)的万向接头装置(32)(一个铰链构件 44),其安装围绕旋转的第一轴(C)和旋转(D)可旋转地的偏离第二轴线。 对于一个健康的人体足部的自然的步态的更精确的再现,本发明提供的是,万向接头机构(32),其可耦合轴侧磁轭(36)的轴(34)和通过接头构件(44)铰接地连接到所述轴侧磁轭(36) 具有与所述轴侧磁轭(36)绕所述第一旋转轴线发生侧节叉(38),(C)和围绕旋转(D)的第二轴线发生侧节叉(38)相对于所述铰链部件(44)枢转,并且所述主体侧的枢转运动 并发生相互节叉(36,38)相对于对至少一个关节部件靠近阻尼器元件的电阻进行的铰链构件(44)。
