Description

Künstliches Bein. Die Erfindung betrifft eine weitere Ausbildung des künstlichen Beines nach Patent 414 982. Die Anordnung ist darin verbessert und vereinfacht, daß die zwei in der Kniegelenkachse hängenden Zugstangen und zwei an dem Oberschenkel angebrachte Druckstangen an zwei an einem Mittelstück des Unterschenkels gelenkig befestigten Hebeln mittels zweier Bolzen angelenkt sind, die kulissenartig in gebogenen Schlitzen des Mittelstückes geführt sind, in welch letzterem ein in einem Schlitz verschiebbares Walzenlager für die Kniegelenkachse vorgesehen ist, dessen Verschiebbarkeit durch die Verstellung einer Wandverkleidung des Schlitzes regelbar ist.Artificial leg. The invention relates to a further embodiment of the artificial leg according to patent 414 982. The arrangement is improved and simplified therein, that the two tie rods hanging in the knee joint axis and two on the thigh attached push rods articulated to two on a middle piece of the lower leg fastened levers are articulated by means of two bolts, the backdrop-like in curved Slots of the middle piece are guided, in which the latter one in a slot Slidable roller bearing is provided for the knee joint axis, its displaceability can be regulated by adjusting a wall cladding of the slot.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung dargestellt, und zwar zeigen: Abb. I eine vordere Ansicht, Abb. 2 eine Seitenansicht mit einer Schnittstelle, Abb.3 einen Querschnitt nach der Linie A-B der Abb. I und Abb.4 einen Querschnitt nach der Linie C-D der Abb. 2.An embodiment of the subject matter of the invention is shown in the drawing shown, namely: Fig. I is a front view, Fig. 2 is a side view with an interface, Fig.3 a cross section along the line A-B of Fig. I and Fig.4 shows a cross-section along the line C-D in Fig. 2.

Wie beim Hauptpatent sind auch hier an der im Knie a gelagerten Kniegelenkachse b zwei Zugstangen m und an der Hinterseite des Knies am Oberschenkel statt nur einer zwei Druckstangen lt vorgesehen. Die Kniegelenkachse b hat ein in einem Schlitz e des an den Unterschenkel anzuschließenden Mittelstückes c verschiebbares mittleres Lager f, das zur leichteren Verschiebung mit vier Walzen versehen ist. Die einfache Verschiebung des Lagers f wird durch die richtige Einstellung einer der beiden seitlichen Schlitzverkleidungen i mittels zweier Schrauben geregelt. Damit die Kniegelenkachse b sich nicht: drehen kann, ist sie durch eine Schraube mit dem Oberschenkel verbunden. Am Mittelstück c sind zwei Hebel g mittels gemeinschaftlicher Achse gelenkig befestigt, und die daran angelenkten zwei Druckstangen h sowie die zwei Zugstangen m sind durch Bolzen h miteinander verbunden, die in gebogenen Schlitzen L des Mittelstückes c bei der Kniebewegung ihre Führung haben.As in the main patent, two tie rods m are provided on the knee joint axis b supported in the knee a and two pressure rods lt are provided on the back of the knee on the thigh instead of just one. The knee joint axis b has a central bearing f which is displaceable in a slot e of the central piece c to be connected to the lower leg and which is provided with four rollers for easier displacement. The simple displacement of the bearing f is regulated by the correct setting of one of the two side slot coverings i by means of two screws. So that the knee joint axis b cannot: turn, it is connected to the thigh with a screw. On the middle piece c, two levers g are articulated by means of a common axis, and the two push rods h articulated thereon and the two tie rods m are connected to one another by bolts h which are guided in curved slots L of the middle piece c during knee movement.

Wie beim Hauptpatent wird auch hier beim Beugen des Knies und beim Sitzen der Unterschenkel und auch das mit demselben verbundene Mittelstück c etwas hochgehoben und das Bein verkürzt, wobei das Maß der Verkürzung durch die Länge der Hebel g und die Angriffsstellen der Stangen h und m bestimmt ist.As with the main patent, here, too, when bending the knee and when Sit the lower legs and also the middle piece c connected to it lifted up and shortened the leg, the measure of the shortening being the length the lever g and the points of application of the rods h and m is determined.

Beim Strecken des Beines wird das Mittelstück c mit dem Unterschenkel etwas abwärts geschoben und das Bein. entsprechend verlängert.When stretching the leg, the middle piece c is with the lower leg pushed down a little and the leg. extended accordingly.
