Abstract

The elements are inserted, and which are computed after lever rule.

Description

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

Der Erfinder ist selbst an beiden Unterschenkeln amputiert und hat bereits anfang 1950 mit künstlichen Füßen als damaliger Versehrtensportler experimentiert. Er ist Urheber des so genannten Aktiv-Kunstfußes, der in seiner Patentschrift DBP 1 261 277 niedergeschrieben ist. Neben Sportprothesen sind von ihm Alltagskunstfüße entwickelt worden, die internationale Erfindungen mit Stahlblattfedern sowie Luftfederungen berücksichtigen und nicht verletzen.Of the Inventor is amputated even on both lower legs and already has early 1950 with artificial Feet as former sportsman experimented. He is the author of so-called active artificial foot, which is written down in his patent DBP 1 261 277. In addition to sports prosthetics, he has developed everyday art feet, the international ones Consider inventions with steel leaf springs as well as air suspensions and do not hurt.

Sie weichen jedoch in der Weise davon ab und sind deshalb den bisherigen künstlichen Füßen überlegen, dass mittels Konstruktionseinfachheit und Leichtgewichtigkeit erstmals die Austauschbarkeit unterschiedlicher Federungselemente, wie Stahl-, Kunststoff- und Luftfederungselemente, einbaumöglich ist, unter verwendung des gleichen Grundaufbaues. Hierbei wird immer die gleiche Federberechnungsformel verwendet, die auf das Hebelgesetzt abgestimmt ist und nachfolgend dargestellt wird. Wenn beispielsweise bei einem Körpergewicht von 75 Kg beim Gehen im Vorfußbelastungspunkt P eine Feder einzubauen ist, so erfolgt die Berechnung nach grosser Hebellänge L ab hinterem Schwenkpunkt Y abzüglich kleiner Hebellänge l bis vorderer oberer Federbefestigung X = P·L/l = 85 Kg. Erfindungsgemäß ist somit durch die weit vorn liegende Federbefestigung X immer ein relativ schwaches und leichtgewichtiges Federungselement einbaumöglich, woraus sich die Überlegenheit der neuen Erfindung ergibt.she However, they differ in the way and are therefore the previous one artificial Consider your feet, that by design simplicity and lightweight for the first time the interchangeability of different suspension elements, such as steel, plastic and air suspension elements, is einbaumöglich, under use of the same basic construction. Here is always the same spring calculation formula used, which is adjusted to the lever set and below is pictured. If, for example, at a body weight 75 Kg when walking in the forefoot stress point If a spring is to be installed, the calculation will be made larger lever length L from rear pivot point Y minus small lever length l to front upper spring attachment X = P · L / l = 85 Kg. According to the invention thus always a relative one due to the spring attachment X at the far front weak and lightweight suspension element fitted, from what the superiority of the new invention.

Die Erfindung ist beispielsweise dargestellt in einer Seitenansicht, teilweise im Schnitt, wobei ein obenliegender leichtgewichtiger nach unter gebogener Halter 1 an seinem hinteren Ende mit zwei hintereinanderliegenden Schrauben 2 die Verbindung zu einem darunterliegenden flachen und gegengekrümmten Stahlfederungselement 3 so herstellt, dass sich an der Verbundungsstelle vorn ein Schwenkpunkt Y ergibt, und auf diese Weise eine nach vorn gerichtete Zangenöffnung entsteht. An den jeweiligen Vorderenden sind Bohrungen 4 und 5 für Verschraubungen 4a und 5a eingerichtet, die ein jeweiliges Federungselement, wie gebogene Kunststoff-Feder 6 oder Stahlblattfeder 7 oder Luftfeder 8, befestigen. Unterhalb der vorderen Befestigungen am Stahlfederungselement 3 ist ein flaches Verbindungsstück 9 für die beliebig gestaltete elastische Fußspitze 10 angeordnet, während hinten am Fuß ein beliebig gestaltetes elastisches Fersenstück 11 installiert ist. Schließlich ist oben am Halter 1 ein beliebiges zweckentsprechendes Befestigungsteil 12 angeordnet und befestigt.The invention is shown, for example, in a side view, partially in section, with an overhead lightweight bent under holder 1 at its rear end with two consecutive screws 2 the connection to an underlying flat and counter-curved steel suspension element 3 is made so that at the junction point forward a pivot point Y results, and in this way creates a forward-facing forceps opening. At the respective front ends are holes 4 and 5 for screw connections 4a and 5a set up a respective suspension element, such as curved plastic spring 6 or steel leaf spring 7 or air spring 8th , fasten. Below the front mounts on the steel suspension element 3 is a flat connector 9 for the arbitrarily designed elastic toe 10 arranged, while at the back of the foot an arbitrarily designed elastic heel piece 11 is installed. Finally, at the top of the holder 1 Any suitable attachment part 12 arranged and fastened.
