Description

Künstlicher Fuß. Die Erfindung betrifft einen künstlichen Fuß und besteht darin, daß Rundfederstahl zu zwei: flachen Schleifen und zwei zwischen den letzteren am Hackenteil befindlichen und diese Schleifen gegeneinander abfedernden Schraubenspiralfedern derart gebogen ist, daß die eine, größere, der beiden flachen Schleifen etwa der Form und Größe des Sohlenrandes entspricht. Die zweite, kleiinere, ist an das Unterschenkelende des Stelzbeines öder der Stützschienen usw. anschließbar. Diese Ausbildung hat den Zweck, eine elastische Gehbewegung auch auf unebenem Boden zu ermöglichen und Stöße bei Zu großer Belastung u. dgl. zu vermeiden.Artificial foot. The invention relates to an artificial foot and consists in making round spring steel to two: flat loops and two between the the latter located on the heel part and cushion these loops against each other Helical coil springs are bent in such a way that one, larger, of the two is flat Sanding roughly corresponds to the shape and size of the edge of the sole. The second, smaller one can be connected to the lower leg end of the pillar or the support rails etc. This training has the purpose of an elastic walking movement even on uneven ground to enable and to avoid shocks if the load is too high and the like.

Auf den Zeichnungen ist der Erfindungsgegenstand beispielsweise in einer Ausführungsform dargestellt, und zwar zeigen Fig. r und 2 Form und Befestigung des künstlichen Fußes an einer sogenannten Skelettprothese ohne Knöchelgelenk im Seiten-und Grundriß, Fig.3 und .4 die Verbindung .des künstlichen Fußes mit einem gewöhnlichen Kunstbein.In the drawings, the subject matter of the invention is shown, for example, in an embodiment shown, namely Fig. R and 2 form and attachment of the artificial foot on a so-called skeletal prosthesis without ankle joint in the Side and ground plan, Fig.3 and .4 the connection. Of the artificial foot with a ordinary artificial leg.

Der künstliche Fuß erhält zwei aus Rundfederstahl gebogene, flache Schleifen a und b und zwei diese Schleifen gegeneinander abfedernde Schraubenspiralfedern c. Die Feder b ist nach Fig. i. und 2 mit der Prothese d und nach Fig. 3 und 4. mit den Seitenschienen e des Unterschenkels des Kunstbeines in üblicher Weise verbunden.The artificial foot has two flat loops a and b made of round spring steel and two helical coil springs c that cushion these loops against each other. The spring b is shown in FIG. and 2 connected to the prosthesis d and according to FIGS. 3 and 4 with the side rails e of the lower leg of the artificial leg in the usual manner.

Der künstliche Fuß wirkt als zweiarmiger, elastischer Hebel, der sich um die Verbindungsachse .r (Fig. 2 und 4) c11-elrt. Infolge der Form und Elastizität des Hebels können Druck- und Zugkräfte in verschiedenster Richtung gleichzeitig angreifen, ohne daß die Hauptwirkung beeinträchtigt wird, d. ii., die beim Schwzben des Fußes automatisch gehobene Fußspitze senkt sich beim Auftreten, beim Abrollen des Fußes wird die Ferse gehoben. Für die Befestigung ist es wesentlich, daß der Unterschenkelteil tief herabreicht, ohne jedoch die Unterlage zu berühren.The artificial foot acts as a two-armed, elastic lever that moves around the connection axis .r (Fig. 2 and 4) c11-elrt. As a result of the shape and elasticity of the lever can push and pull forces in different directions at the same time attack without affecting the main effect, d. ii., the Schwzben the toe, which is automatically raised, lowers when stepping on, when rolling off of the foot the heel is lifted. For the attachment it is essential that the Lower leg part reaches down deeply, but without touching the surface.

Die Form und Befestigungsart der Rundstahlfeder bewirkt, daß die Fußbewegungen nicht ruckweise, sondern harmonisch erfolgen, ganz gleichgültig, ob ein Unterschenkelteil ohne oder mit Knöchelgelenk getragen wird oder ob es sich um eine Rohrprothese, unten geschlossene Unterschenkelhülse, Hülse mit doppelseitigen Schienen handelt. Sie sind auch unabhängig von der Beschaffenheit der Bodenoberfläche.The shape and type of fastening of the round steel spring causes the foot movements not in jerks, but harmoniously, regardless of whether a lower leg part is worn with or without an ankle joint or whether it is a tubular prosthesis, Lower leg sleeve closed at the bottom, sleeve with double-sided splints. They are also independent of the nature of the soil surface.

Der Unterschenicelteil des Ersatzgliedes behält auch bei Belastung seine jeweilige natürliche .Stellung bei, weil der Kunstfuß liehen der Senkung der Fußspitze beim Auftreten und der Hebung der Ferse beim Abrollen des Fußes die für unebenen Boden so wichtigen -Drehungen um die Längsachse, d, h. Hebung und Senkung des inneren oder äußeren Fußrandes ausführen kann. Dadurch kommt eine ständige Kontrolle der Augen beim Aufsetzen des Fußes in Wegfall. Bei etwaiger Überbelastung wird das Körpergewicht durch den dann den Boden berührenden U nterschenkelteil mit aufgefangen. Selbst im Falle der Bescliädigung des Kunstfußes ist der Träger des Ersatzgliedes nicht hilflos, sondern geht auf der Stelze oder dem Gehbügel.The lower leg part of the replacement limb retains even under load its respective natural position because the artificial foot lent the lowering of the The tip of the foot when stepping on and the heel is lifted when rolling the foot for uneven ground so important - rotations around the longitudinal axis, d, h. Up and down of the inner or outer edge of the foot. This means that there is constant control of the eyes when putting the foot down in omission. If there is any overload, this will be Body weight is also absorbed by the lower leg part then touching the floor. Even in the case of damage to the artificial foot the carrier the replacement limb is not helpless, but walks on the stilt or the walking stirrup.

Bei der Billigkeit des Materials würde eine Auswechslung der Fußfeder gegebenenfalls am zweckmäßigsten sein. Die Auswechslung kann ohne Schwierigkeiten von denn Träger selbst vorgenommen werden. Bei passender Größe hält der Kunstfuß selbsttätig irn Stiefel: Urü den künstlichen Fuß der natürlichen Form anzupassen, wird er mit einer Tuch-, Filz-oder Lederverkleidung versehen, doch genügt es schon, einen Strumpf herüberzuziehen, der mit Watte, Zellstoff, Holzwolle u. dgl. ausgestopft wird.Given the cheapness of the material, the foot spring would have to be replaced may be most appropriate. The substitution can be done without difficulty be made by the carrier itself. If the size is right, the artificial foot will hold automatically in the boot: Urü to adapt the artificial foot to the natural shape, it is provided with a cloth, felt or leather covering, but it is enough pulling over a stocking stuffed with cotton wool, cellulose, wood wool and the like will.

Im Bedarfsfalle kann auch das Gewicht des Fußes durch beliebig schwere Einlagen in die Verkleidung abgeändert werden.If necessary, the weight of the foot can also be increased by any heavy Inlays in the fairing can be modified.
