Description

BeschreibungDescription

Gefederter / gedämpfter Unterschenkel für Prothesen.Sprung / dampened lower leg for prostheses.

Übliche Unterschenkel aus der Modularbauweise für Oberschenkel -,Unterschenkel - und Knieexprothesen sind aus starren Metall - oder Kohlefaserrohren hergestellt. Diese lassen keinerlei Federung oder Dämpfung zu. Beim Gehen, Laufen oder anderen Tätigkeiten bekommt der Benutzer bei jedem Schritt einen Stoß auf seinen Stumpf und/ oder sein Becken . Diese negative Wirkung führt auf Dauer zu Schmerzen.Conventional modular lower legs for thigh, lower leg and knee prostheses are made of rigid metal or carbon fiber tubes. These do not allow any kind of suspension or cushioning. When walking, running or doing other activities, the user is hit on their stump and/or pelvis with every step. This negative effect leads to pain in the long term.

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, einen Unterschenkel zu schaffen, der für alle Füße geeignet, leicht in die modulare Bauweise einzubauen und leicht auszuwechseln ist. Außerdem soll er leicht und verdrehsicher sein, aber trotzdem eine geräuschlose und komfortable Federung / Dämpfung aufweisen. Diese Probleme sind mit den im Schutzanspruch aufgeführten Merkmalen gelöst.The invention specified in the protection claim is based on the problem of creating a lower leg that is suitable for all feet, easy to install in the modular design and easy to replace. In addition, it should be light and twist-proof, but still have noiseless and comfortable suspension/damping. These problems are solved with the features specified in the protection claim.

Mit dieser Erfindung wird erreicht, daß der Prothesenbenutzer beim Gehen ,Laufen oder bei anderen Tätigkeiten - auf Dauer gesehen - sich schmerz- und problemfrei bewegen kann. Man kann denn gefederten / gedämpften Unterschenckel in fast jede Prothese ohne großen Aufwand einbauen. Der Fuß ist verdrehsicher mit dem Knie verbunden. Durch die handelsüblichen Anschlüsse ist er leicht einzubauen und auszuwechseln. Die kompakte Bauweise ermöglicht leichtes Gewicht. Durch Auswechseln der Elastomere / Feder läßt sich die Dämpfung/Federung auf jeden Benutzer individuell einstellen.This invention means that the prosthesis user can move without pain or problems when walking, running or performing other activities - in the long term. The spring-loaded/cushioned lower leg can be installed in almost any prosthesis without great effort. The foot is connected to the knee in a twist-proof manner. The standard connectors make it easy to install and replace. The compact design makes it lightweight. By replacing the elastomers/springs, the damping/suspension can be individually adjusted to each user.

In der Zeichnung ist die Erfindung in zwei Ansichten dargestellt. In der Vorderansicht kann man die Feder / Elastomere sehen. An das Teil E wird ein beliebiger Fuß mit Hilfe der Madenschrauben I befestigt, an Teil A ein beliebiges Knie. Beim Gehen, Laufen oder anderen Tätigkeiten wird der Auftrittsdruck vom Fuß zum Teil E über Teil D auf die Einstellschraube F übertragen. Mit Hilfe dieser Schraube kann man die Feder / Elastomere vorspannen, und so auf jedes Körpergewicht bzw. jede Tätigkeit einstellen. Im weiteren wird die Kraft über Teil A auf Teil B übertragen. Die entstehenden Kräfte , die gegeneinander wirken, werden von der Feder / Elastomere gedämpft. Beim Wiedervorholen des Fußes wird die Feder / Elastomere entlastet und dehnt sich in die ursprüngliche Länge aus. Dadurch bekommt der Fuß noch einen leichten Schub und wird beschleunigt. Dadurch verringert sich der Energieaufwand, der für diesen Vorgang benötigt wird. Um ein Verdrehen zwischen Teil A und D zu verhindern ist Teil C eingebaut.The invention is shown in two views in the drawing. The front view shows the spring/elastomer. Any foot can be attached to part E using the grub screws I, and any knee can be attached to part A. When walking, running or performing other activities, the pressure from the foot to part E is transferred via part D to the adjustment screw F. This screw can be used to pre-tension the spring/elastomer and thus adjust it to any body weight or activity. The force is then transferred via part A to part B. The resulting forces, which act against each other, are dampened by the spring/elastomer. When the foot is moved forward again, the spring/elastomer is relieved and stretches to its original length. This gives the foot a slight push and accelerates it. This reduces the energy required for this process. Part C is installed to prevent twisting between parts A and D.
