Description

Zu der im Hauptpatent 726 228 wiedergegebenen Sperr- und Bremsvorrichtung für Kunstbeinkniegelenke wird erfindungsgemäß eine Schalt- und Auslösevorrichtung vorgeschlagen, die nicht nur eine willkürliche Betätigung und Lösung der Bremsvorrichtung, sondern auch eine fast automatische Wirkung ermöglicht. Diese neuartige Ausgestaltung der Sperr- und Bremsvorrichtung besteht aus einer hebelartig schwenkbaren Pelotte am oberen Stumpfhülsenrand des Kunstbeines, einer Pelotte, die bei Belastung des Kunstbeines und durch Abduktion des Stumpfes unter den Druck der Bauchwandung oder der äußeren Hüft- und Schenkelfläche gerät, dadurch ausschwenkt und mittels eines Schnurzuges die Bremsvorrichtung nach Patent 726 228 einschaltet. Beim Anheben des Kunstbeines als Spielbein wird die Pelotte wieder entlastet und damit die Bremsung und Sperrung gelöst. To the locking and braking device reproduced in the main patent 726 228 according to the invention, a switching and triggering device is used for artificial knee joints proposed that not only an arbitrary actuation and release of the braking device, but also enables an almost automatic effect. This novel design the locking and braking device consists of a lever-like pivoting pad on the upper edge of the stump sleeve of the artificial leg, a pad that, when the Artificial leg and by abduction of the stump under the pressure of the abdominal wall or the outer hip and thigh surface, thereby swiveling out and using a Pull cord switches on the braking device according to patent 726 228. When lifting the Using the artificial leg as a free leg, the pad is relieved again and with it the braking and lock released.

In der Zeichnung ist diese zusätzliche Neuerung in einer beispielsweisen Ausführung zur Darstellung gebracht. Abb. I zeigt einen Teilungsschnitt durch das Kunstbein, Abb. 2 eine Draufsicht auf die Oberschenkelhülse. This additional innovation is shown as an example in the drawing Execution brought to the display. Fig. I shows a dividing section through the Artificial leg, Fig. 2 a top view of the thigh sleeve.

Demnach ist am oberen Rand der Oberschenkelstumpfhülse 7 ein pelottenartig gegen die Hüftseite gepolsterter Hebel (Pelottenhebel) a angebracht, der mit einem in der anderen Richtung hinaus verlängerten Arm b das obere Ende der Zugschnur g erfaßt. Dieses Zugmittel ist entsprechend dem Hauptpatent über die Rolle 10 am Kniegelenk in das Unterschenkelteil I mit der Sperr- und Bremsvorrichtung verbunden. Dadurch ist nun erreicht, daß beim Aufsetzen des Kunstbeines, d. h. beim Belasten, die Hüftteile des Kunstbeinträgers den Pelottenhebel a ein wenig nach unten verschwenken, so daß der Hebelarm b hochgeht, welche Bewegung genügt, um den Bremshebel anzuziehen, der die Klemmung bewirkt. Die Lösung der Bremswirkung erfolgt automatisch durch das Anheben des Kunstbeines als Spielbein, weil damit zugleich der Pelottenhebel entlastet wird. Andererseits ist es beim Aufstehen aus der Sitzstellung möglich, das Kunstbein mit abgebeugtem Knie zu belasten, indem der Kunstbeinträger den Pelottenhebel unter Druck hält. Ein Anziehen, d. h. Abduzieren des Stumpfes, bewirkt dagegen ein willkürliches Freigeben des Kniegelenks. Der Amputierte kann also nicht nur in jeder Beugestellung des Kunstbeines dasselbe als Stütze benutzen, er kann auch, sich jeweils auf das abgebeugte Kunstbein stützend, aufstehen und sich aufrichten. Accordingly, on the upper edge of the thigh stump sleeve 7 is a pelotte-like against the hip side padded lever (pad lever) a attached, which with a in the other direction, arm b extended the upper end of the pull cord g recorded. According to the main patent, this traction means is via the roller 10 on the knee joint connected to the lower leg part I with the locking and braking device. Through this is now achieved that when placing the artificial leg, i. H. when straining, the hip parts of the artificial leg support pivot the pad lever a a little downwards so that the lever arm b goes up, which movement is sufficient to pull the brake lever, the causes the clamping. The braking effect is automatically released by the Lifting the artificial leg as a free leg, because this also relieves the pressure on the pad lever will. On the other hand, it is possible to use the artificial leg when getting up from the sitting position load with bent knee by placing the artificial leg support underneath the pad lever Pressure holds. A tightening, d. H. Abduction of the stump, on the other hand, produces an arbitrary one Release the knee joint. The amputee can therefore not only be in every flexion position of the artificial leg use the same as a support, he can also rely on the Support bent artificial legs, stand up and straighten up.

Es ist, wie schon angedeutet, auch möglich, den Pelottenhebel gegen die Bauchseite des Amputierten hin anzuordnen, wenn andere Belastungen und bewußt eingeleitete Sperrungen erzielt werden sollen. As already indicated, it is also possible to counteract the pad lever to arrange the ventral side of the amputee towards when other loads and consciously initiated blocks are to be achieved.

Auch kann der mit der Erfindung gebotene Pelottenhebel gegebenenfalls mit anderen Gelenksperren am Kunstbein in Verbindung gebracht werden.The pad lever provided with the invention can also optionally be associated with other joint locks on the artificial leg.
