Description

Die Erfindung betrifft ein Kniegelenk für Oberschenkelprothesen. The invention relates to a knee joint for thigh prostheses.

Außerordentlich nachteilig wurde es von allen Protbesenträgern bislang empfunden, daß ein Kniegelenk nur dann fest stand, wenn das Kunstbein ganz durchgedrückt war. Sobald das Kunstbein in geknickter Stellung stand, hatte der Prothesenträger keinen Halt auf der Prothese. Es machte sich dies insbesondere beim Treppensteigen nachteilig bemerkbar. So far it has been extremely disadvantageous for all protbes wearers felt that a knee joint was only stable when the artificial leg was pushed through completely was. As soon as the artificial leg was in a bent position, the prosthesis wearer had no hold on the prosthesis. This was especially true when climbing stairs disadvantageously noticeable.

Erfindungsgemäß wird nun eine Bremse vorgeschlagen, die das künstliche Kniegelenk in jeder Stellung festhält, sobald die Prothese durch das Körpergewicht belastet wird. According to the invention a brake is now proposed that the artificial Holds the knee joint in any position as soon as the prosthesis is supported by the body weight is charged.

Die Zeichnung zeigt die Erfindung nur im Schema. The drawing shows the invention only in the scheme.

Der künstliche Oberschenkel in seiner normalen Ausführung ist in ein Oberteil 1 und ein Unterteil 2 geteilt, die sich in einem bestimmten Abstand in Pfeilrichtung 3 gegeneinander verschieben lassen. Beide Teile I und 2 werden durch regelbaren Federdruck normal, also in unbelastetem Zustand, auseinandergehalten, so wie dies in der Schemazeichnung dargestellt ist. Innerhalb der beiden Teile I und 2 ist ein Stößel 4 angeordnet, der in belastetem Zustand der Prothese nach unten gedrückt wird (Pfeilrichtung 5). Sein unteres Ende 6 ist gelenkartig an dem Bremsengestänge befestigt, wobei die Bremse selbst in geeigneter Form in dem künstlichen Kniegelenk vorgesehen ist. The artificial thigh in its normal design is in an upper part 1 and a lower part 2 divided, which are at a certain distance Can be shifted against each other in the direction of arrow 3. Both parts I and 2 will be Normally held apart by adjustable spring pressure, i.e. in an unloaded state, as shown in the schematic drawing. Within the two parts I. and 2 a plunger 4 is arranged, which in the loaded state of the prosthesis downwards is pressed (direction of arrow 5). Its lower end 6 is articulated on the brake linkage attached, the brake itself in a suitable form in the artificial knee joint is provided.

Diese Bremse kann eine normale Backenbremse, innen oder außen im Ausführungsbeispiel als Innenbackenbremse dargestellt. Oldruckbremse o. dgl. 7 sein, nur muß sie derart wirken, daß im gebremsten Zustand eine Bewegung des Kniegelenkes unmöglich ist.This brake can be a normal shoe brake, inside or outside in the exemplary embodiment shown as an inner shoe brake. Oil pressure brake o. The like. 7, it just has to be that way act that in the braked state movement of the knee joint is impossible.

Belastet also der Prothesenträger durch sein Körpergewicht den Oberschenkel, so drückt der Stößel 4 nach unten und damit die Gelenkstücke 8 der Bremse in die -.--Linie, wodurch die Bremsbacken angezogen werden. Die Bewegung des Kniegelenkes ist damit gesperrt. Sobald die Belastung aufhört, löst sich auch die Bremse und eine Bewegung des Kniegelenkes ist möglich. So if the prosthesis wearer loads the thigh with their body weight, so the plunger 4 pushes down and thus the joint pieces 8 of the brake in the -.-- Line, whereby the brake shoes are tightened. The movement of the knee joint is thus blocked. As soon as the load ceases, the brake and also release movement of the knee joint is possible.

Selbstverständlich kanii die Bremse auch derart gebaut werden, daß der Druck vom Fuß aus erfolgt, also der Stößel nach oben wirkt. Auch ist es möglich, den Stößel als Koil,en einer ()ldruckbremse auszubilden, wobei man den durch die Belastung erzeugten öldruck dann in geeigneter Form als Bremse auf das Kniegelenk einwirken läßt. Of course, the brake can also be built in such a way that the pressure comes from the foot, so the plunger acts upwards. It is also possible to design the tappet as a coil of an () oil pressure brake, whereby the through the Load then produced oil pressure in a suitable form as a brake on the knee joint can act.

PATENTANSPRUCH Kniegelenk für Oberschenkelprothesen, dadurch gekennzeichnet, daß durch einen bei Belastung des Ober- oder Unterschenkels hervorgerufenen Druck in Richtung auf das Kniegelenk eine in ihm vorgesehene Bremse betätigt wird, die eine weitere Funktion des Kniegelenkes in jeder Lage sperrt und die Bremswirkung bei Aufhören der Belastung durch den Druck einer Feder aufgehoben wird, wodurch das Kniegelenk wieder beweglich wird. PATENT CLAIM Knee joint for thigh prostheses, characterized in that that caused by pressure on the thigh or lower leg in the direction of the knee joint a brake provided in it is actuated, which Another function of the knee joint blocks in every position and the braking effect when the load is stopped by the pressure of a spring, whereby the knee joint becomes mobile again.
