Description
Gegenstand der Erfindung ist ein künstlicher Fuß mit Doppelfederung, bei welchem die Drehachse des Fußgelenks und der Führungsbölzen für die Doppelfederung hintereinander in dem unteren Ende der Tragschienen des Unterschenkels gelagert sind und das Doppelfederwerk in dem Fuße angeordnet ist. Dadurch wird nicht nur das Fußgelenk wesentlich gefestigt, sondern auch eine kurzThe invention relates to an artificial foot with double suspension, in which the axis of rotation of the ankle and the guide bolts for the double suspension one behind the other are stored in the lower end of the support rails of the lower leg and that Double spring system is arranged in the foot. This not only makes the ankle essential consolidated, but also a short one
ίο bauende Konstruktion geschaffen, also auch das Gewicht des Doppel'federwerks erheblich verringert, was von besonderem Vorteil ist. Auf der Zeichnung" ist, der Erfindungsgegenstand beispielsweise dargestellt, und zwar zeigt:ίο building construction created, so too the weight of the Doppel'federwerk significantly reduced, which is of particular advantage. The subject of the invention is shown in the drawing, for example, and although shows:
Fig. ι einen Längsschnitt durch den künstlichen Fuß und
. Fig. 2 eine Seitenansicht desselben.Fig. Ι a longitudinal section through the artificial foot and
. Fig. 2 is a side view of the same.
Der künstliche Fuß besteht in bekannter Weise aus zwei Teilen α und b, welche durch die federnde Sohle c und den Balg d miteinander verbunden sind. Die Drehachse / des Fußgelenks und der Führungsbolzen, i für die Doppelfederung sind in dem unteren Ende der seitlichen Tragschienen g des Unterschenkels hintereinander gelagert. Der Führungsbolzen i ist quer durch eine mit Doppelbolzen versehene Spannschraube η gesteckt, welche zu diesem Zwecke in ihrer Mitte mit einem Auge versehen ist und die in dem Fuße durch ober- und unterhalb des Führungsbolzens i angeordnete Federn I und m gestützt und so verschiebbar angeordnet ist. Die Spannung der Federn I und m kann mittels der Muttern ο und p nach Belieben geändert werden. Die über dem Führungsbolzen liegende Feder / ist schwächer als die.unter demselben liegende Feder m. Dadurch wird erreicht, daß beim Auftreten die schwache Feder / wirksam wird und sich der Fuß dem Erdboden leicht anpaßt, während beim Gehen über die Fußspitze die starke Feder in wirksam wird und eine kräftige Spannung verursacht, die den Zehengang des Invaliden ermöglicht. Um ein Kreischen der Federn zu verhüten, sind unter 'dieselben bzw. in dieselben Lederscheiben bzw. Lederbüchsen eingelegt. The artificial foot consists in a known manner of two parts α and b, which are connected to one another by the resilient sole c and the bellows d. The axis of rotation / the ankle and the guide pin, i for the double suspension are mounted one behind the other in the lower end of the lateral support rails g of the lower leg. The guide pin i is inserted transversely through a clamping screw η provided with double bolts, which for this purpose is provided with an eye in its center and which is supported in the foot by springs I and m arranged above and below the guide pin i and is thus arranged so that it can be moved . The tension of springs I and m can be changed as required using nuts ο and p. The spring / lying above the guide pin is weaker than the spring m below it. This ensures that the weak spring / becomes effective when stepping on and the foot easily adapts to the ground, while when walking over the tip of the foot the strong spring in takes effect and creates a strong tension that enables the disabled person to walk in the toe. In order to prevent the feathers from screeching, the same leather washers or leather sleeves are inserted underneath or in the same.
