Description
Künstliche Füße mit einem während .des Gehens regelbaren Knöchelgelenk, behufs Anpassung der Neigung des Fußes an die Neigung des Geländes, sind bereits bekannt. Gegenüber diesen verhältnismäßig.komplizierten und daher zumeist nicht sehr dauerhaften und umständlich zu handhabenden Konstruktionen beabsichtigt die vorliegende Erfindung eine neue einfachere Lösung der Aufgabe.Artificial feet with a during .des Walking adjustable ankle joint, for adapting the incline of the foot to the incline of the site are already known. Compared to these relatively complicated ones and therefore mostly not very durable and cumbersome to handle constructions the present invention intends a new, simpler solution to the problem.
Die neue Konstruktion läßt sich leicht derart weiter ausbilden, daß dem Fuße außer der dem Gelände entsprechenden Neigung auch eine dem Geschwindigkeitsgrade der Gangart angepaßte Beweglichkeit und Elastizität gegeben werden kann.The new construction can easily be further developed in such a way that the foot apart from the The slope corresponds to the terrain and the speed of the gait adapted mobility and elasticity can be given.
An einem in der Zeichnung wiedergegebenen Ausführungsbeispiele ist die Erfindung erläutert.The invention is based on an exemplary embodiment shown in the drawing explained.
Am Tragrohr 1 ist ein Ring 2 mit exzen-On the support tube 1 is a ring 2 with eccentric
ao irischer Wulst mittelsi eines Kabels 3 entgegen der Spannung einer Rückschlagfeder 4 begrenzt verdrehbar angeordnet. Durch die Drehung des Wulstringes 2 wird die Neigung einer Schwinge 5, die mittels Verspannungsmittel 6, 8 mit dem Fußunterteil verbunden ist, eingestellt. Die Fig. 1 stellt die Lage der Schwinge und des Fußes beim Gehen auf horizontalem Boden dar, während die Fig. 2 und 3 die beiden einander entgegengesetzten Grenzlagen der Schwinge beim Aufwärts- und beim Abwärtsgehen auf geneigtem Boden darstellen.ao Irish bead by means of a cable 3 against the tension of a check spring 4 is arranged to be rotatable to a limited extent. Through the Rotation of the bead ring 2 is the inclination of a rocker 5, which by means of bracing means 6, 8 is connected to the lower part of the foot. Fig. 1 represents the location of the Swing and the foot when walking on horizontal ground, while Fig. 2 and 3 the two opposite limit positions of the rocker arm in the upward and when walking downhill on sloping ground.
Durch eine größere, oder kleinere Drehung des Wulstringes 2 kann dem Fuße jede gewünschte Neigung innerhalb der Grenzlagen gegeben werden; diese Drehung geschieht mittels des Kabels 3, das. z. B. von der Hosentasche aus angespannt werden kann.A larger or smaller rotation of the bead ring 2 can give the foot any desired Inclination can be given within the limit positions; this rotation is done by means of of the cable 3, the. B. can be tightened from the pocket.
Um den Fuß nicht nur der Neigung des Bodens, sondern auch dem Geschwindigkeitsgrade der jeweiligen Gangart anzupassen, ist der Erfindungsgegenstand wie folgt weiter ausgebildet. Der Wulstring 2 ist auf dem Rohr 1 nicht nur drehbar, sondern auch längs desselben begrenzt verschiebbar angeordnet. Die Verschiebung des Wulstringes 2 wird wiederum mittels eines Kabels 3' entgegen dem Druck derselben Rückschlagfeder 4 bewirkt, die nunmehr auf Druck anstatt auf Torsion beansprucht wird. Durch die Längsverschiebung des Wulstringes 2 wird zwischen letzterem und der Schwinge'5 ein freier Spielraum von regelbarer Größe geschaffen, durch welchen der Fuß eine entsprechend große Beweglichkeit erhält. Wie bekannt, ist eine solche um so erwünschter, je langsamer die Gangart ist. Durch die beschriebene Einrichtung kann in jedem Augenblick eine der Geschwindigkeit der Gangart angepaßte Beweglichkeit des Fußes eingestellt werden.To the foot not only the slope of the ground, but also the degree of speed to adapt to the respective gait, the subject matter of the invention is further developed as follows. The bead ring 2 is not only rotatable on the tube 1, but also along the same Slidably arranged to a limited extent. The displacement of the bead ring 2 is again caused by means of a cable 3 'against the pressure of the same return spring 4, which is now based on pressure instead of torsion is claimed. The longitudinal displacement of the bead ring 2 is between the latter and the Schwinge'5 a free space of adjustable size created by which the foot receives a correspondingly large mobility. As is known, is one the slower the pace, the more desirable. Through the facility described can at any moment a mobility adapted to the speed of the gait of the foot can be adjusted.
Verspannungsmittel bestehen in Führungsstangen 6, die von Schraubenfedern 8 umschlungen sind. Um zu be'wirken, daß diese Federn bei den verschiedenen Stellungen derBracing means consist of guide rods 6 around which helical springs 8 are wrapped are. In order to cause these springs to move in the various positions of the
Schwinge 5 immer nur in Richtung ihrer Achse, also hier nur auf Druck, beansprucht werden, was sehr wichtig ist, wenn die Federn nicht der Gefahr eines Bruches an ihren Befestigungsstellen ausgesetzt sein sollen, sind die Federn -mittels der Winkelplatten 9 mit dem Fußunterteil derart verbunden, daß die eine Schenkelplatte als Widerlager den Druck der Feder 8 begrenzt, während die andere an dem unteren Fußteil angelenkt ist.Swing 5 is always stressed only in the direction of its axis, that is to say here only under pressure which is very important if the springs are not exposed to the risk of breakage at their attachment points the springs are connected to the lower part of the foot by means of the angle plates 9 in such a way that that the one leg plate as an abutment limits the pressure of the spring 8, while the other is hinged to the lower foot part.
Bei der Ausführungsform gemäß Fig. 5 sind die Schwinge 5 und dieVerspannungsmittel 6, 8 durch die an sich bei Knöchelgelenken bekannte Leyer-förmige Feder 7 ersetzt; die Wirkungsweise des drehbaren oder auch verschiebbaren Wulstringes 2 bleibt im wesentlichen die gleiche.In the embodiment according to Fig. 5, the rocker 5 and the tensioning means are 6, 8 replaced by the Leyer-shaped spring 7 known per se in ankle joints; the The mode of operation of the rotatable or also displaceable bead ring 2 remains essentially the same.
