Description

Das Hauptpatent 936 I6I bezieht sich auf einen Kunstfuß für Beinamputierte, dessen Luftblase ein Ventil besitzt, welches durch die Verkleidung geführt ist und in eine Aussparung des Knöchelteiles hineinragt. The main patent 936 I6I relates to an artificial foot for leg amputees, whose air bladder has a valve which is guided through the panel and protrudes into a recess in the ankle part.

Gemäß der Erfindung besitzt die - Luftblase im oberen Teil eine Öffnung, in die eine Abdeckplatte und der Kopf des Knöchelbolzens derart eingreifen, daß der Rand der Abdeckplatte im Innern der Gummiblase aufliegt und nach Anziehen des Knöchelbolzens luftdicht mit der Luftblase abschließt. According to the invention, the air bubble has an opening in the upper part, engage in a cover plate and the head of the ankle bolt in such a way that the edge of the cover plate rests on the inside of the rubber bladder and after tightening the The ankle bolt is airtight with the air bubble.

Ein weiteres Merkmal der Erfindung besteht darin, daß der Knöchelbolzen einen Luftkanal besitzt, in den ein Luftventil fest eingreift, wobei das Luftventil waagerecht in einer Bohrung des Knöchelbolzens vorgesehen ist. Durch diese Anordnung einer Öffnung im oberen. Teil der Gummiblase besteht ein Vorteil darin, daß nach der Herstellung der Luftblase das eingeführte Leistenstück bequem herausgenommen werden kann. Dadurch wird ermöglicht, daß die Gummiblase aus einem Stück ohne Naht hergestellt werden kann, die sonst - durch Zusammenheften, z. B. durch Vulkanisieren, entsteht. Durch diese Herstellung der Luftblase behält der Kunstfuß seine anatomische Form. Another feature of the invention is that the ankle bolt has an air channel in which an air valve is firmly engaged, the air valve is provided horizontally in a hole in the ankle bolt. Through this arrangement an opening in the upper. Part of the rubber bladder has an advantage that after the introduced piece of last conveniently removed during the production of the air bubble can be. This enables the rubber bladder to be made from one piece without a seam can be produced, which otherwise - by stitching, z. B. by vulcanizing, arises. By creating the air bubble in this way, the artificial foot retains its anatomical shape Shape.

Die Verlegung des Luftventils hat gegenüber -dem Hauptpatent den Vorteil, daß dieses nicht mehr durch eine Bohrung der Luftblase geführt wird, sondern mit dem hohl ausgebildeten Knöchelbolzen in Verbindung steht, so daß eine Beschädigung der Luftblase vermieden wird. The relocation of the air valve has compared to the main patent The advantage that this is no longer passed through a hole in the air bubble, but with the hollow knuckle bolt is in connection, so that damage the air bubble is avoided.

In der Zeichnung ist ein Ausführungsstück des Gegenstandes nach der Erfindung - dargestellt, und es zeigt Abb. I eine Vorderansicht des Kunstfußes- im Schnitt, Abb. 2 eine Draufsicht von Abb. I im Schnitt durch die Bohrung des Luftventils. In the drawing is an execution piece of the subject after Invention - shown, and it shows Fig. I a front view of the artificial foot in section, Fig. 2 is a plan view of Fig. I in section through the bore of the air valve.

Der Kunstfuß besteht aus der Gummiblase I, in welcher eine Öffnung I3 vorgesehen ist. Diese Öffnung 13 ist einmal von außen durch eine mit einem Loch für den Durchgang des Knöchelbolzens 7 vorgesehene Verkleidung 4 überdeckt, auf der in bekannter Weise das Knöchelstück 8 aufliegt. Innen, unter- der Bohrung I3 der Luftblase I, ist eine versteifte Abdeckplatte I4 vorgesehen, durch deren Bohrung der mit einem begrenzten Luftkanal 15 versehene -Knöchelbolzen 7 greift. Waagerecht durch das Knöchelstück 8 ist eine Bohrung 12 vorgesehen, in welche das Luftventil II eingeführt ist und mit dem Luftkanal Ig des Knöchelbolzens 7 luftdicht verbunden ist PATENTANSPROCHE: 1. Kunstfuß für Beinamputierte nach Patent 936 S6I, dadurch gekennzeichnet, da&- die Luftblase (I) im oberen Teil eine Öffnung (I3) be-Sitzt, in die eine Abdeckplatte (I4) und der Kopf des Knöchelbolzens (7) derart eingreifen, daß der Rand der Abdeckplatte (14) im Innern der Gummiblase (I) aufliegt und nach Anziehen des KnöchelboIzens (7) luftdicht mit der Gummiblase (1) abschließt. The artificial foot consists of the rubber bladder I, in which an opening I3 is provided. This opening 13 is once from the outside through a with a hole covering 4 provided for the passage of the ankle bolt 7, on which the knuckle 8 rests in a known manner. Inside, under the hole I3 the air bubble I, a stiffened cover plate I4 is provided through the hole the knuckle pin 7, which is provided with a limited air channel 15, engages. Horizontal through the knuckle piece 8 a bore 12 is provided, into which the air valve II is inserted and connected airtight to the air duct Ig of the ankle bolt 7 is PATENT APPLICATION: 1. Artificial foot for leg amputees according to patent 936 S6I, thereby marked because & - the air bubble (I) has an opening (I3) in the upper part, into which a cover plate (I4) and the head of the ankle bolt (7) engage in such a way that that the edge of the cover plate (14) rests inside the rubber bladder (I) and after Tighten the ankle bolt (7) and seal it airtight with the rubber bladder (1).

2. Kunstfuß für Beinamputierte nach Anaspruch 1, dadurch gekennzeichnet, daß der Knöchelbolzen (7) einen begrenzten Luftkanal (I5) besitzt, in den ein in einer Bohrung (I2) des Knöchelstückes (8) angeordnetes Luftventil (11) luftdicht eingreift. 2. artificial foot for leg amputees according to claim 1, characterized in that that the ankle bolt (7) has a limited air channel (I5) into which an in a hole (I2) of the knuckle (8) arranged air valve (11) airtight intervenes.

Claims (1)

3. Kunstfuß für Beinamputierte nach Anspruch I und 2, dadurch gekennzeichnet, daß bei Beschädigung der Luftblase (I) dieselbe auswechselbar ist. 3. artificial foot for leg amputees according to claim I and 2, characterized in that that if the air bubble (I) is damaged, it can be replaced.
