Description
Die Erfindung bezieht sich auf eine Fußprothese, die einen außerordentlich elastischen Auftritt gewährleistet und bei der infolge der gleichmäßigen Belastung die Ermüdungserscheinungen auf ein Mindestmaß herabgesetzt werden. Hierdurch wird der Beinstumpf besonders geschont, und es ist sogar möglich, bei Unterschenkelamputierten an Stelle des bisher verwendeten langen Oberschaftes nur eine kurze Manschette zu verwenden. The invention relates to a prosthetic foot that is extremely elastic appearance guaranteed and in the result of the even load the signs of fatigue are reduced to a minimum. This will the leg stump is particularly spared, and it is even possible for lower leg amputees instead of the long upper stock used up to now, only a short cuff is closed use.
Gemäß der Erfindung wird eine Blattfeder verwendet, die den gesamten Druck aufnimmt. Diese ist so gelagert, daß auch der vordere Teil der Fußprothese unter ihrem Einfluß steht und gelenkig gestaltet werden kann und daß ferner genügend Spiel für eine begrenzte Kippbewegung nach den Seiten hin verbleibt. According to the invention, a leaf spring is used, the entire Takes up pressure. This is positioned so that the front part of the prosthetic foot is also is under their influence and can be articulated and that, furthermore, sufficient There remains play for a limited tilting movement to the sides.
Die erfindungsgemäß verwendete Blattfeder ist gewölbt und besitzt zwischen ihrem vorderen, auf der Prothesensohle in der Längsrichtung frei beweglich aufliegenden Ende und ihrem hinteren, gegen die Prothesensohle überhöht abgestützten Ende ein Scharnier zur Befestigung des Knöchelstücks. The leaf spring used according to the invention is curved and has between its front, freely movable in the longitudinal direction on the prosthesis sole resting end and its rear, supported against the prosthesis sole excessively End of a hinge to attach the ankle piece.
Um eine seitliche Kippbewegung zu ermöglichen, wird für die Abstützung zwischen Federende und Sohle ein begrenzt schwenkbares Kugelgelenk verwendet, während zwischen Knöchelstück und Kugelgelenk ein Puffer gelagert wird, so daß das Knöchelstück unter Vermittlung des Puffers auf dem Kugelgelenk lose aufliegt. In order to enable a lateral tilting movement, is used for the support between the end of the spring and the sole a limited pivoting ball joint is used, while a buffer is stored between the ankle joint and the ball joint, so that the ankle joint rests loosely on the ball joint with the intermediary of the buffer.
Der Prothesenvorderteil ist mit dem Mittelstück gelenkig verbunden, so daß auch hierdurch ein reguläres Gehen mit der Prothese gewährleistet ist. The front part of the prosthesis is articulated to the middle part, so that this also ensures regular walking with the prosthesis.
Die Blattfeder besteht zweckmäßig aus mehreren Lagen, von denen aber nur eine bis zur Spitze durchgeht, während die anderen unter einer auf der Prothesensohle sitzenden Brücke hindurchgesteckt sind. Sämtliche Lagen werden durch eine unmittelbar neben dem Scharnier angeordnete Spange zusammengehalten. Zu dieser Ausführung besitzt die Feder die den ausgeübten Belastungen entsprechende Elastizität. The leaf spring expediently consists of several layers, but one of them only one goes through to the tip, while the other goes under one on the prosthetic sole seated bridge are pushed through. All layers are immediately clasp arranged next to the hinge held together. Owns to this version the spring has the elasticity corresponding to the loads exerted.
Der Erfindungsgegenstand ist auf der Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Fig. 1 einen Schnitt nach der Linie A-B der Fig. 2, Fig. 2 einen Schnitt nach der Linie C-D der Fig. 1. The subject of the invention is shown in the drawing in an exemplary embodiment shown, namely Fig. 1 shows a section along the line A-B of Fig. 2, FIG. 2 shows a section along the line C-D of FIG. 1.
Die Fußprothese besteht aus einem vorteilhaft aus Leichtmetall hergestellten Hohlkörper mit dem Fersen- oder Hinterteil I, dem Mittelteil 2 und dem Vorder- oder Zehenteil 3. Ferse I und Mittelteil 2 bestehen aus einem Stück, während der Zehenteil 3 mit dem Mittelteil 2 gelenkig verbunden ist. Diese gelenkige Verbindung erfolgt einerseits durch die unter die Prothesensohle 4 bzw. 4' geklebte Ledersohle 5, unter die dann noch eine Gummi sohle 6 geklebt werden kann. Andererseits ist der Vorderteil 3 mit Hilfe des Bolzens 7 und des Schlitzes 8 in dem Mittelteil 2 beweglich geführt. The prosthetic foot consists of an advantageously made of light metal Hollow body with the heel or rear part I, the middle part 2 and the front or Toe part 3. Heel I and middle part 2 consist of one piece, while the toe part 3 is articulated to the middle part 2. This articulated connection is made on the one hand by the leather sole 5 glued under the prosthesis sole 4 or 4 ', under which then a rubber sole 6 can be glued. The other hand is the front part 3 movably guided in the middle part 2 with the aid of the bolt 7 and the slot 8.
Der aus Leichtmetall bestehende Körper wird dann noch mit Leder überzogen. The light metal body is then covered with leather.
In diesem Hohlkörper liegt die aus mehreren Lagen g, IO, 11 und I2 bestehende Blattfeder. Die Lage g dieser Blattfeder geht als einzige bis zum Zehenstück durch. Die Lagen 9, Io und ii werden durch die Brücke I3, welche auf der Sohle 4 befestigt ist, niedergehalten. Im übrigen werden sämtliche Lagen g bis 12 durch die Spange 14 zusammengehalten. This hollow body consists of several layers g, IO, 11 and I2 existing leaf spring. The position g of this leaf spring is the only one up to the toe piece by. The layers 9, Io and ii are made by the bridge I3, which is on the sole 4 is attached, held down. In addition, all layers g to 12 are through the clasp 14 held together.
Diese Spange 14 sitzt unmittelbar neben dem Scharnier I5, dessen einer Teil fest auf der oberen Lage 12 der Blattfeder sitzt, während der andere Teil des Scharniers an dem Knöchelstück i6 befestigt ist. Beide Scharnierhälften werden durch den Scharnierbolzen 17 miteinander verbunden. Am äußersten Ende sind sämtliche Lagen der Blattfeder durch ein Kugelgelenk mit der Kugel i8 gegen die Sohle 4 abgestützt. Dieses Gelenk ist aber infolge der vorstehenden Kanten 19 nur begrenzt nach den Seiten hin kippbar. This clasp 14 sits immediately next to the hinge I5, whose one part sits firmly on the upper layer 12 of the leaf spring, while the other Part of the hinge is attached to the ankle piece i6. Both hinge halves are connected to one another by the hinge pin 17. At the very end are all positions of the leaf spring by a ball joint with the ball i8 against the Sole 4 supported. This joint is only 19 due to the protruding edges can be tilted to the sides to a limited extent.
Oberhalb dieses Kugelgelenks ist ein Gummipuffer 20 vorgesehen, welcher im Knöchelstück I6 sitzt. A rubber buffer 20 is provided above this ball joint, which sits in the ankle piece I6.
PATENTANSPRSCHE: I. Fußprothese mit aus Blattfeder bestehender Längsfederung, dadurch gekennzeichnet, daß die Blattfeder (9 bis I2) in der Längsrichtung gewölbt ist und zwischen ihrem vorderen, auf der Prothesensohle in der Längsrichtung frei beweglich aufliegendem Ende und ihrem hinteren, gegen die Prothesensohle überhöht abgestützten Ende ein Scharnier (I5) zur Befestigung des Knöchelstücks besitzt. PATENT CLAIMS: I. Foot prosthesis with longitudinal spring suspension consisting of leaf springs, characterized in that the leaf spring (9 to I2) is arched in the longitudinal direction is and between its front, free on the prosthetic sole in the longitudinal direction movable end and its rear, raised against the prosthesis sole supported end has a hinge (I5) for fastening the ankle piece.
