Description

Die Erfindung bezieht sich auf eine Fußprothese und verbessert die Beweglichkeit des Fußes gegenüber dem übrigen Teile der gesamten Prothese. The invention relates to and improves a prosthetic foot Mobility of the foot in relation to the rest of the prosthesis as a whole.

Gemäß Erfindung werden die Fußteile und der Schaft des Unterschenkelteiles durch ein Kugelgelenk miteinander verbunden, so daß es dem Prothesenträger ermöglicht wird, den Fuß auch seitlich zu bewegen, womit die Starrheit des unteren Teiles des Beines aufgehaben und beim Laufen über unebene Bodenflächen ein natürliches und sicheres Gehen gewährleistet wird. According to the invention, the foot parts and the shaft of the lower leg part connected by a ball joint, so that it allows the prosthesis wearer will also move the foot sideways, reducing the rigidity of the lower part of the And when walking over uneven surfaces a natural and safe walking is guaranteed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt Abb. I den Fuß in Seitenansicht und Teilschnitt und Abb. 2 den Querschnitt nach der Linie A-B. In the drawing, an embodiment of the invention is shown, namely Fig. I shows the foot in side view and partial section and Fig. 2 shows the cross section after the line A-B.

In den Abbildungen ist a das untere Ende des Schaftes des Unterschenkels und b die Fußprothese. In the figures, a is the lower end of the shaft of the lower leg and b the prosthetic foot.

Auf der Sohle c, die aus Leichtmetall bestehen kann, ist das Gehäuse d befestigt, in dem der Bolzen e mit Hilfe des Rahmens f gelagert ist. Auf dem Bolzen e sitzt die Kugel g, auf der sich der Ring h allseitig bewegen kann, da er schmäler ist als der Durchmesser der Kugelg. Um diesen Gelenkteilg,h erfolgt die gesamte gegenseitige Bewegung von Fuß und Schaft des Unterschenkels nach allen Seiten.The housing is on the sole c, which can be made of light metal d attached, in which the bolt e is mounted with the help of the frame f. On the bolt e sits the ball g, on which the ring h can move in all directions, because it is narrower is than the diameter of the Kugelg. To this joint part, h takes place the entire mutual movement of the foot and shaft of the lower leg in all directions.

Um das freie Spiel dieser Bewegung in natürlichen Grenzen zu halten, sind die Gummipufferi zwischen den beiden Prothesenteilen eingeschaltet dergestalt, daß bei Nichtbeanspruchung des Fußes dieser durch die Gummipuffer i aus der seitlichen Stellung in die normale Stellung zurückgeführt wird.In order to keep the free play of this movement within natural limits, the rubber buffers between the two prosthesis parts are switched on in such a way that that when the foot is not stressed it is removed from the side by the rubber buffers i Position is returned to the normal position.

Die beiden Gummipuffer können solche Länge haben, daß sie nach dem Zusammenbau der beiden Prothesen unter Spannung stehen und im Zusammenwirken mit der am hinteren Fußende angeordneten Zugfeder k der ganzen Prothese eine elastische Festigkeit sichern, trotz allseitiger elastischer Beweglichkeit des Gelenkfußes. The two rubber buffers can have such a length that they after Assembling the two prostheses are under tension and interacting with the tension spring k of the entire prosthesis arranged at the rear end of the foot is an elastic one Ensure stability, despite the elastic mobility of the articular foot on all sides.

Die neue Anordnung läßt gegenüber der bekannten die Verwendung von Metall ohne weiteres zu und durch den Ersatz des Holzes durch Metall wird die Lebensdauer und Festigkeit der Fußprothese wesentlich erhöht. Infolge des einfachen Aufbaues der neuen Fußprothese kann man diese ohne weiteres an bereits vorhandene hölzerne Unterschenkelschäfte anbringen. The new arrangement can be compared to the known the use of Metal easily becomes too and by replacing the wood with metal increases the lifespan and strength of the prosthetic foot is significantly increased. Due to the simple structure the new prosthetic foot can easily be attached to existing wooden ones Attach lower leg stems.

NachAbb. I ist an derFußspitze eine keilförmige Aussparung vorgesehen, die mit einem nachgiebigen Stoff I, z. B. mit Schwammgummi, ausgefüllt ist, so daß eine bewegliche Fußspitze entsteht. According to Fig. I a wedge-shaped recess is provided at the tip of the foot, those with a resilient fabric I, z. B. is filled with sponge rubber, so that a movable toe is created.
