Description

Die Erfindung betrifft die Gestaltung eines dynamischen künstlichen Fußes für Beinamputierte.The invention relates to the design of a dynamic artificial foot for amputees.

Der Erfinder ist selbst an beiden Unterschenkeln amputiert und hat bereits Anfang 1950 mit künstlichen Füßen experi­ mentiert. Als junger Sportler - 100Meterläufer und Weit­ springer - ist er der Urheber des sogenannten Aktiv-Kunst­ fußes, der in seiner Patentschrift DBP 1 261 277 nieder­ geschrieben ist. Seine früheren Entwicklungsarbeiten wur­ den seinerzeit von den zuständigen deutschen Prothesen­ verordnungsstellen dadurch boykottiert, daß die mit sei­ nen Aktivkunstfüßen möglichen Läufe und Sprünge bei den deutschen Versehrtensportveranstaltungen verboten wurden.The inventor himself is amputated on both lower legs and already in early 1950 had experi with artificial feet mented. As a young athlete - 100m runner and far springer - he is the originator of the so-called active art Fußes, who is listed in his patent specification DBP 1 261 277 is written. His previous development work was at that time by the responsible German prosthesis boycotted regulation bodies by being with them possible active runs and jumps in the German sports events were banned.

Später sind auch in den USA dynamische Kunstfüße entwic­ kelt worden: VA Seattle-Fuß. Seither werden diese Kunst­ füße fälschlich als Basiserfindung genannt. Zweifellos sind damit unter Verwendung neuer Materialien Fortschrit­ te erzielt worder, und ebenfalls in Deutschland sind die alten Sportveranstaltungsgegner nicht mehr vorhanden.Later, dynamic artificial feet were also developed in the USA celt: VA Seattle foot. Since then, this art feet incorrectly named as a basic invention. Undoubtedly are progress using new materials te was achieved, and also in Germany old opponents of sporting events no longer exist.

Bei dieser neuen Erfindung ist jetzt ein besonders leich­ ter und konstruktionseinfacher dynamischer Kunstfuß ent­ standen, der sich sowohl für den Alltagsgebrauch als auch für den Sportbetrieb hervorragend eignet. Er ist je nach Konzeption unterschiedlich herstellbar. Die Basis bildet dabei ein leicht s-förmige Blattfeder, die als Vorfuß­ schwinge ausgelegt und lediglich mit einem handelsüblichen Gewindebolzen in einem gebräuchlichen Prothesenwadenteil verschraubt ist. Dieses Waden- oder Knöchelteil wird da­ bei nach vorn unten abgerundet gestaltet und als Feder­ stütze ausgebildet. Zur Seitenstabilisierung ist ferner ein sehr kleiner, senkrechtstehender Stift eingearbeitet, der von unten in das Wadenteil eingreift. Die Blattfeder/­ Vorfußschwinge bildet nach vorn unten mehr oder weniger die Vorfußsohle und ist je nach Aufgabe unterschiedlich gestaltet. Das Fersenstück ist getrennt vom Vorfuß ange­ ordnet und ebenfalls je nach Aufgabe unterschiedlich her­ gestellt, wobei spezielle Hohlkörper/Gummihohlfedern er­ fahrungsgemäß bevorzugt werden. Der Vorteil dieser Erfin­ dung liegt neben der Leichtgewichtigkeit und verschiede­ nen Verwendbarkeit in der sehr preisgünstigen Herstel­ lungsweise aufgrund seiner sehr einfachen Konstruktion. Erfindungsgemäß ist als zusätzliche Neuheit, nach Fig. 2, ein schuhloser dynamischer Sport-Kunstfuß entwickelt wor­ den.With this new invention, a particularly light and constructionally simple dynamic artificial foot has arisen, which is excellently suited for everyday use as well as for sports. It can be manufactured differently depending on the concept. The base is formed by a slightly S-shaped leaf spring, which is designed as a forefoot swingarm and is only screwed into a conventional prosthetic calf part with a standard threaded bolt. This calf or ankle part is designed rounded at the front and down as a spring support. For side stabilization, a very small, vertical pin is also incorporated, which engages in the calf section from below. The leaf spring / forefoot rocker more or less forms the forefoot sole towards the front and is designed differently depending on the task. The heel piece is arranged separately from the forefoot and also made differently depending on the task, with special hollow bodies / hollow rubber springs according to experience. The advantage of this inven tion lies in addition to the light weight and various NEN usability in the very inexpensive manufacture because of its very simple construction. According to the invention as an additional novelty, according to FIG. 2, a shoe-free dynamic sports artificial foot has been developed.

Die Erfindung ist beispielsweise dargestellt in drei Fi­ guren. Die Fig. 1 zeigt den neuen dynamischen Kunstfuß in Seitenansicht, teilweise im Schnitt, wobei eine etwa s-förmig gestaltete Blattfeder 1 die Basis in der Weise bildet, daß ein starker, senkrechtstehender Gewindebolzen 2 die allgemein übliche Verbindung zum Prothesenwadenteil 3 herstellt. Dieses Prothesenteil ist dabei so gestaltet, daß es sich nach vorn unten mehr oder weniger weit in den Kunstfuß einschiebt und eine abgerundete Stütznase 4 für die Blattfeder 1 bildet, an der die Blattfeder bei Bela­ stung des Vorfußes abrollend nach oben schwenkt. (Auch Vorfußschwinge genannt). Die Blattfeder bildet dabei in vorbestimmter Form gleichzeitig die Vorfußsohle mit auf­ gesetzter und allgemein üblicher Fußspitze 5. Das Fersen­ teil wird durch einen separaten Hohlkörper 6 gebildet, der oben an einem schräggestellten Prothesenwadenteil 3 und unten schräg nach vorn an der Blattfeder 1 anliegt und beliebig befestigt ist. Hinter dem Gewindebolzen 2 wird ein Sicherungsstift 7 integriert, der senkrecht nach oben in das Wadenteil eingreift. The invention is illustrated, for example, in three fi gures. Fig. 1 shows the new dynamic artificial foot in side view, partly in section, with an approximately S-shaped leaf spring 1 forms the basis in such a way that a strong, vertical threaded bolt 2 creates the common connection to the prosthetic calf part 3 . This prosthesis part is designed so that it is inserted more or less far forward into the artificial foot and forms a rounded support nose 4 for the leaf spring 1 , on which the leaf spring rolls at the load of the forefoot rolling upward. (Also called forefoot swing). The leaf spring also forms the forefoot sole in a predetermined form with the toe 5 placed and generally customary. The heel part is formed by a separate hollow body 6 , which rests at the top on an inclined prosthesis calf part 3 and at the bottom obliquely forward on the leaf spring 1 and is fastened as desired. Behind the threaded bolt 2, a locking pin 7 is integrated, which engages vertically upwards in the lower leg part.

Der in Fig. 2 teilweise im Schnitt und in Seitenansicht dargestellte dynamische Kunstfuß ist als leichter Sport­ fuß konzipiert, der schuhfrei und somit besonders gewicht­ sparend konstruiert worden ist. Der Aufbau erfolgt im we­ sentlichen nach Figur in Verbindung mit einer sogenannten Blattfeder-Vorfußschwinge 1, die vorn in der Längsmitte geschlitzt und hinten mit einem starken Gewindebolzen 2 im Wadenteil 3 der Prothese befestigt wird. Erfindungs­ gemäß ist hierbei die Vorfußschwinge an ihrer Unterseite mit sogenannten Stollen 8 oder ähnlich bestückt, wie sie sonst in der üblichen Weise bei Sportschuhen befestigt sind. Die Fersenhohlfeder 6 ist unten an ihrem Auftritts­ teil mit einer Rutschbremse 9 ausgerüstet und in der ge­ bräuchlichen Art mit dem Wadenteil verbunden. Als kosme­ tischer Vorfußansatz wird vorn am Knöchelteil der Prothe­ se ein mehr oder weniger großer Vorsatz 10 angeordnet und befestigt. In Fig. 3 wird die Vorfußfederschwinge 1 nach Fig. 2 in Draufsicht dargestellt. Sie ist in ihrem Vorder­ teil in Längsrichtung geschlitzt, so daß zwei gleiche Hälften entstehen, die vorn abgerundet sind. Auf diese einfache Weise ergibt sich eine für einen Sportfuß wich­ tige Seitenelastizität.The dynamic artificial foot shown partially in section and in side view in FIG. 2 is designed as a light sports foot that has been constructed shoe-free and thus particularly weight-saving. The structure is essentially based on the figure in connection with a so-called leaf spring forefoot swing 1 , which is slit in the front in the longitudinal center and fastened at the rear with a strong threaded bolt 2 in the calf part 3 of the prosthesis. Invention according to this is the forefoot swing on its underside with so-called studs 8 or similar, as they are otherwise attached in the usual manner in sports shoes. The heel hollow spring 6 is equipped at the bottom of its appearance with a slip brake 9 and connected in the common ge with the calf part. As a cosmic forefoot approach, a more or less large attachment 10 is arranged and fastened at the front of the ankle portion of the prosthesis. In Fig. 3, the Vorfußfederschwinge 1 of FIG. 2 is shown in plan view. It is slotted in the front part in the longitudinal direction, so that two equal halves are formed, which are rounded at the front. In this simple way, there is an important side elasticity for a sports foot.
