 sammengeschraubt zu werden. Sodann werden die Federn 9 auf die festen oder verstellbaren Federhalter 10 aufgesetzt, das Ansatzstück 11 auf dem vier-oder mehrkantigen Teil der Stange 4 nachgepresst und mit der Mutter 16 festgeschraubt. Sämtliche Kugellager ruhen in Lagerschalen. 



    PATENTANSPRÜCHE :    
1. Knöchelgelenk für Beinprothesen, welches sowohl eine Bewegung des Fusses in Pro- und Supination als auch in Spitz-und Hakenfussstellung gestattet und bei welchem diese Bewegungsmöglichkeiten durch schwenkbare Lagerung des Fusses um zwei zueinander senkrechte Achsen und durch Federn, welche den Fuss in einer Mittelstellung zu halten suchen, erzielt werden, dadurch gekennzeichnet, dass eine Verbindungsstange (4) zwischen Unterschenkel und Fuss im Unterschenkel um eine zur Fusslängsrichtung parallele Achse (4a) schwenkbar gelagert ist, und durch eine in Verlängerung der Stange (4) liegende Zugfeder (8) oder durch zwei in Fussquerrichtung liegende Druckfedern, die zwischen dem Stangenoberteil (4) und dem Stöckel   (1)   aufsitzen, in Richtung der Unterschenkelachse gehalten wird,

   während der Fuss an dieser Verbindungsstange (4) um eine zu seiner Längsrichtung senkrechte : Achse (4b) schwenkbar gelagert ist und durch zwei in der Fusslängsrichtung liegende Federn (9) relativ zur Stange in einer Mittelstellung gehalten wird.

 to be screwed together. The springs 9 are then placed on the fixed or adjustable spring holders 10, the extension piece 11 is pressed onto the square or polygonal part of the rod 4 and screwed tight with the nut 16. All ball bearings rest in bearing shells.



    PATENT CLAIMS:
1. Ankle joint for leg prostheses, which allows both a movement of the foot in pronation and supination as well as in the pointed and hooked foot position and in which these possibilities of movement by pivoting the foot around two mutually perpendicular axes and by springs that keep the foot in a central position seek to hold, are achieved, characterized in that a connecting rod (4) between the lower leg and foot is mounted in the lower leg so as to be pivotable about an axis (4a) parallel to the longitudinal direction of the foot, and by a tension spring (8) lying in extension of the rod (4) or is held in the direction of the lower leg axis by two compression springs lying in the transverse direction of the foot, which sit between the upper bar part (4) and the heel (1)

   while the foot on this connecting rod (4) is pivotably mounted about an axis (4b) perpendicular to its longitudinal direction and is held in a central position relative to the rod by two springs (9) lying in the longitudinal direction of the foot.

 

Claims (1)

2. Knöchelgelenk nach Anspruch 1, dadurch gekennzeichnet, dass die Federn (9) im Fuss an einem Ansatzstück (11) angreifen, welches auf einem Vierkant der Stange (4) aufgeschoben ist, wobei die Federn auf festen oder verstellbaren Federhaltern (10) aufsitzen. 2. Ankle joint according to claim 1, characterized in that the springs (9) act in the foot on an extension piece (11) which is pushed onto a square of the rod (4), the springs being seated on fixed or adjustable spring holders (10) . 3. Knöchelgelenk nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Lager der Achsen als Wälzlager ausgebildet sind. 3. Ankle joint according to claim 1 or 2, characterized in that the bearings of the axles are designed as roller bearings.
