Description

Die Erfindung bezieht sich auf ein künstliches Fußgelenk, welches sich bei Belastung nach allen Seiten in verschieden starkem Maße jeder Flächenstellung des Bodens elastisch anpaßt. The invention relates to an artificial ankle which with load on all sides to different degrees in every surface position elastically adapts to the soil.

Das Fußoberteil 1 (Abb. 1) ist mit dem Fußunterteil II durch eine Schraube 5 verbunden. Der Kopf der Schraube 5 lagert auf einer Halbkugel 2, welche durch eine Druckfeder 3 den Kopf der Schraube 5 elastisch abfängt, um bei Belastung den Spannungsausgleich der Schraube 5 herzustellen. The upper foot part 1 (Fig. 1) is with the lower foot part II by a Screw 5 connected. The head of the screw 5 rests on a hemisphere 2, which by means of a compression spring 3 the head of the screw 5 is elastically intercepted to withstand stress to establish the tension compensation of the screw 5.

Das untere Ende der Schraube 5 sist mit der Halbkugel mutter 6 verbunden. Die Halbkugeln 2 und 6 ruhen auf Kugellagerschalen I und 7, welche mid dem Oberteil I und Unterteil II fest verbunden sind.The lower end of the screw 5 sist with the hemisphere nut 6 connected. The hemispheres 2 and 6 rest on ball bearing shells I and 7, which mid the upper part I and lower part II are firmly connected.

Die Gummiplatte 8, deren Ober- und Unterflächen 15 nach innen gewölbt geformt sind, liegt zwischen Oberteil I und Unterteil II. Die Platte 8 erstreckt sich über die ganze Breite des Fußes, sichert somit die Dauerhaftigkeit der Platte und verleiht hohe Elastizität und leichte Regulierbarkeit (Abb. 2).The rubber plate 8, the upper and lower surfaces 15 of which are curved inward are formed, lies between upper part I and lower part II. The plate 8 extends extends over the entire width of the foot, thus ensuring the durability of the plate and gives high elasticity and easy adjustability (Fig. 2).

Abb. 2 zeigt den Schnitt durch das Gelenk gemäß Abb. I, bei welcher die Gummiplatte 8 geradlinig durch die ganze Breite des Fußgelenkes läuft, w6 durch ein stärkerer Widerstand bei seitlicher Bewegung gegeben ist. Die Gummiplatte 8 ist in der Mitte o durchbrochen, durch welche die Schraube 5 läuft. In der Fersengegend des Fußunterteiles II läuft nach oben in das Oberteil 1 das Zugseil oder Stange I I, welche oben mit einem Kopf g und unten mit Gewinde I6 und Kugelmutter 14- in der Lagerschale 13 versehen ist. Oben ruht der Kopf g auf einem elastischen Puffer 10, in dessen Aussparung eine Druckfeder t-2-sjtzt. Mit Hilfe der Andng der Zugstange II kann durch Anziehen der Kugselmutter I4 die Fußstellung verändert, der Anschlag nach vorn bei Belastung begrenzt werden, ohne daß die Gummiplatte 8 an -Wirksamkeit verliert. Der Fersenauftritt nach hinten ist durch die zentrale Anordnung der Gummiplatte 8 weich, was bisher wegen Raummangel bei Anbringung mehrerer Druckkörper unvollkommen gelöst wurde. Infolge günstiger Form der Gummiplatte 8, die zwischen den frei schwebenden Kugellagerschalenschrauben 5 ruht, konnte selbst nach langem Gebrauch kein Verschweiß festgestellt werden.Fig. 2 shows the section through the joint according to Fig. I, in which the rubber plate 8 runs straight through the entire width of the ankle, w6 through there is greater resistance when moving sideways. The rubber plate 8 is perforated in the middle o, through which the screw 5 runs. In the heel area of the lower foot part II runs up into the upper part 1, the pull rope or rod I I, which at the top with a head g and at the bottom with a thread I6 and ball nut 14- in the bearing shell 13 is provided. At the top, the head g rests on an elastic buffer 10, in the recess of which a compression spring t-2-sjtzt. With the help of the tension rod II can change the foot position by tightening the spherical nut I4, the stop be limited to the front under load without the rubber plate 8 at -effectiveness loses. The heel strike to the rear is due to the central arrangement of the rubber plate 8 soft, which was previously imperfect due to lack of space when attaching several pressure bodies has been resolved. As a result of the favorable shape of the rubber plate 8 between the freely floating Ball bearing shell screws 5 at rest, could not weld even after long use to be established.
