Description

Künstliches. Bein Die Erfindung betrifft ein künstliches Bein, dessen Fuß mit dem Schenkel durch einen elastischen Gelenkbolzen aus Gummi verbunden ist, und bezweckt eine Steigerung der Elastizität des Fußgelenkes und eine völlige Entlastung der üblichen Stoßpuffer bei der Rückführung nach Abbiegen des Fußes, so daß eine wesentliche Erhöhung der Gehgeschwindigkeit möglich ist. Dies wird erfindungsgemäß dadurch erreicht, daß der vorzugsweise aus einem schlauchartigen Gummigewebe bestehende Gelenkbolzen eine ebenfalls aus Gummi bestehende Gelenkkugel durchsetzt, welche zwei als Stütz- und Gelenkflächen dienende zonenförmige Metallauflagen trägt.Artificial. Leg The invention relates to an artificial leg, the The foot is connected to the leg by an elastic joint pin made of rubber, and aims to increase the elasticity of the ankle and complete relief the usual shock buffer when returning after turning the foot, so that a substantial increase in walking speed is possible. This is according to the invention achieved in that the preferably consisting of a hose-like rubber fabric A joint ball also made of rubber passes through the joint bolt, which carries two zone-shaped metal supports serving as support and joint surfaces.

Die Erfindung bietet besonders bei solchen künstlichen Beinen Vorteile, bei welchen durch besondere Vorrichtungen am Kniegelenk Änderungen der Gehgeschwindigkeit möglich sind.The invention offers advantages particularly in the case of such artificial legs, in which by special devices on the knee joint changes in walking speed possible are.

In der Zeichnung ist eine Ausbildungsform der Erfindung veranschaulicht, und zwar zeigt: Abb. i einen axialen Längsschnitt von der Seite und Abb.2 einen axialen Längsschnitt durch den Fuß von hinten gesehen.In the drawing, an embodiment of the invention is illustrated, namely shows: Fig. i an axial longitudinal section from the side and Fig.2 a axial longitudinal section through the foot seen from behind.

Wie aus der Zeichnung ersichtlich, ist das Fußgelenk derart ausgebildet, daß die vorderen und hinteren Gelenkflächen e1 zum Mittelpunkt die Mitte der Gelenkkugel f1 aufweisen. Der Fuß ist nach den nämlichen Krümmungen ausgehöhlt unter Freilassung eines genügenden Spielraums. Es sind ferner Widerlager hl vorgesehen, welche die den verschiedenen Neigungen des Erdbodens entsprechenden Bewegungen begrenzen. Die Gelenkkugel f 1 besteht aus Kautschuk und ist mit einer senkrechten Bohrung versehen zur Aufnahme eines schlauchartigen Gummigewebes g1. Letzteres ist unter Spannung oben in den Hohlraum p1 des Fußknöchelstückes mittels eines Stütz- und Druckringes il und unten auf ähnliche Weise mittels des Ringes j1 in der Fußsohle hl befestigt. Die Kautschukgelenkkugel f1 ist teilweise mit Metallkalotten h abgedeckt, welche eine Drehbewegung gestatten. Um ein möglichst geringes Gewicht -zu erzielen,. ist der Fersenteil ml in bekannter Weise ausgehöhlt und der Vorderteil n1 des Fußes aus Kork mit Lederüberzug hergestellt, welcher die Gelenkfugen abdeckt. Zur Begrenzung der Gehbewegung dient ein Band s1, welches am Fuß und am Knöchelstück t1 befestigt ist.As can be seen from the drawing, the ankle joint is designed in such a way that that the anterior and posterior joint surfaces e1 to the center point the center of the joint ball have f1. The foot is hollowed out following the same curvature, leaving it free sufficient leeway. There are also abutments provided which the limit movements corresponding to the different slopes of the ground. the Joint ball f 1 is made of rubber and has a vertical hole for receiving a hose-like rubber fabric g1. The latter is under tension above into the cavity p1 of the ankle piece by means of a support and pressure ring il and attached below in a similar manner by means of the ring j1 in the sole of the foot hl. The rubber joint ball f1 is partially covered with metal caps h, which allow a rotary movement. In order to achieve the lowest possible weight. is the heel part ml is hollowed out in a known manner and the front part n1 of the foot Made of cork with a leather cover, which covers the joint joints. To the limit A band s1, which is attached to the foot and to the ankle piece t1, is used for walking is.
