Description
Kniegelenk für Oberschenkelkunstbeine. Die Erfindung betrifft ein Kniegelenk für Oberschenkelkunstbeine und besteht darin, daß in der Gegend der Kniekehle ein an sich bekannter Gummipuffer in eine Aussparung des Kniestückes eingelassen ist, welcher gegen einen an den Schienen des Oberschenkels angenieteten und an den Rand der Lederhülse des Oberschenkels sich anschmiegenden Metallbügel drückt.Knee joint for artificial thighs. The invention relates to a Knee joint for artificial thighs and consists in that in the region of the hollow of the knee a known rubber buffer let into a recess in the knee is, which is riveted against one on the rails of the thigh and on the Edge of the leather sleeve of the thigh presses the metal bracket snugly.
Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigt Abb. = einen Längsschnitt und Abb. 2 einen Querschnitt durch das Kniegelenk.The subject of the invention is shown in one embodiment in the drawing shown, namely Fig. = shows a longitudinal section and Fig. 2 shows a cross section through the knee joint.
Die Verbindung zwischen dem Oberschenkel a und dem Unterschenkel b erfolgt durch eine das Kniestück b durchbohrende Aussparung c, durch die ein Gelenkbolzen geführt wird, an dem die beiden am Oberschenkel a angenieteten Schienen d befestigt sind. Dieser Gelenkbolzen läuft in einem Lederlager e. An den Schienen des Oberschenkels d ist ein Stahlband f angenietet, das um die Hinterhälfte des Kniestückes b herumläuft und bis an die Lederhülse i des Oberschenkels a heranreicht. In dem Kniestück ist eine Aussparung g vorgesehen, in die ein Gummipuffer k eingeführt ist, der durch seine Ausdehnungsfähigkeit sich einesteils gegen das Stahlband f und anderenteils gegen die Rückwand der Aussparung g preßt.The connection between the thigh a and the lower leg b takes place through a recess c which pierces the knee b and through which a hinge pin is guided, to which the two rails d riveted to the thigh a are attached. This hinge pin runs in a leather bearing e. A steel band f is riveted to the rails of the thigh d, which runs around the rear half of the knee b and reaches up to the leather sleeve i of the thigh a. A recess g is provided in the elbow, into which a rubber buffer k is inserted, which, due to its expandability, presses itself against the steel band f on the one hand and against the rear wall of the recess g on the other.
Im Gegensatz zu den bisherigen Konstruktionen, die nur mit einem feiten Anschlag hergestellt werden, gestattet diese Anordnung ein Überstrecken des Gelenkes, durch die der Gummipuffer zusammengepreßt wird. Die durch das Ausdehnungsbestreben des Gummipuffers entstandene Kraftaufspeicherung wirkt beim Abrollen des Beines derart, daß das ganze Bein in etwas gebeugter Kniestellung nach vorn gebracht wird, so daß der Beinbeschädigte weder die Muskelkraft des Stumpfes, noch sonstige Vorrichtungen hierzu benötigt, die denselben Zwecken dienen, wie Gummizüge, Federbandagen u. dgl.In contrast to the previous designs, which only work with one Stop are made, this arrangement allows an overstretching of the joint, through which the rubber buffer is compressed. The one through the striving for expansion The accumulation of force created by the rubber buffer acts when the leg rolls off in such a way that the whole leg is brought forward in a slightly bent knee position, so that the leg injured neither the muscular strength of the stump, nor other devices required for this purpose, which serve the same purposes as elastic bands, spring bandages and the like.
