Description

Künstlicher Fuß. Die vorliegende Erfindung betrifft einen künstlichen Fuß und besteht darin, daß der Fuß gegen den Unterschenkel außer durch zwei an sich bekannte, hauptsächlich. zum Geradehalten des Fußes dienende Federn noch durch ein die Knöchelgelenkachse mit dem Fuß .unmittelbar verbindendes elastisches Lager abgefedert wird.Artificial foot. The present invention relates to an artificial one Foot and consists in that the foot against the lower leg except by two in itself known, mainly. springs used to hold the foot straight through a the ankle joint axis with the foot .immediately connecting elastic bearing is cushioned will.

Das Lager kann in verschiedener Weise ausgestaltet sein. In der Zeichnung ist als beispielsweise Ausführungsform die Verwendung von Gummipuffern gewählt, und zwar zeigt: Abb. r eine Ansicht mit teilweisem Schnitt im Aufriß, Abb. a eine Draufsicht bei abgenommener Schiene, Ablr.3 eine Ansicht von unten bei abgenomrnener Deckplatte, Abb. q. die Deckplatte allein.The camp can be designed in various ways. In the drawing the use of rubber buffers is chosen as an example embodiment, namely shows: Fig. r a view with a partial section in elevation, Fig. a a Top view with the rail removed, Obl. 3 a view from below with the removed rail Cover plate, fig.q. the cover plate alone.

a bezeichnet den Unterschenkel, b den Fuß. Auf derFußplatte stehen die beiden bekannten Spiralfedern c und d, welche die Gelenkbewegung, die sich beim Gehen ergibt, abfedern. Die hintere Feder c ist zum Teil in eine in dem Unterschenkel a befindliche Kammer e eingelassen. Auf der vorderen Feder d liegt der UnterSt'.henkel lose auf.. f ist die Knöchelgelenkachse, auf welcher der Unterschenkel mit einem Gegenprofil g lose aufsitzt. Die Achse f wird von zwei Gewindebolzen h getragen. Diese Bolzen sitzen lose in je einer Bohrung i und treten aus dieser Bohrung in je eine Kammer h ein, wo ihnen je ein Napf l angeschlossen ist, der je einen Gummipuffer in trägt. Die beiden Kammern münden in eine flache Aussparung n, welche von einer Abdeckplatte o abgeschlossen wird, deren Befestigung mittels zweier Mutterbolzen p erfolgt. Auf der Innenfläche der Platte stehen zwei Näpfe r, welche zur Führung der unteren Enden der Puffer m ,dienen.a denotes the lower leg, b the foot. The two well-known spiral springs c and d, which cushion the joint movement that occurs when walking, stand on the footplate. The rear spring c is partially embedded in a chamber e located in the lower leg a. The lower leg rests loosely on the front spring d. F is the ankle joint axis on which the lower leg rests loosely with a counter profile g. The axis f is carried by two threaded bolts h. These bolts each sit loosely in a bore i and emerge from this bore into a chamber h , where a cup l is connected to each, each carrying a rubber buffer. The two chambers open into a flat recess n, which is closed by a cover plate o, which is attached by means of two nut bolts p. On the inner surface of the plate are two cups r, which serve to guide the lower ends of the buffer m.

Die Puffer stützen also die Knöchelgelenkachse mittelbar ab, so daß sie in ihnen ein federnd elastisches Auflager findet. Die damit erzielte Wirkung ist gerade an dieser Stelle sehr wichtig und vorteilhaft.The buffers therefore support the ankle joint axis indirectly, so that she finds a resilient elastic support in them. The effect achieved with it is very important and beneficial at this point.

Die Puffer müssen in ihrer Kammer etwas Spielraum haben, damit sie sich nicht quetschen bzw. stauchen können, was die Elastizität beeinträchtigen würde.The buffers must have some leeway in their chamber so that they cannot squeeze or compress, which would affect the elasticity.
