Abstract

The innovation relates to use of magnets which oppose each other with the same poles (n) and result in a cushioning effect due to magnetic fields (f). According to the drawing, the magnets are attached so as to be rotatable downwards during application (a), so that a cushioning is produced by the magnetic fields during loading. By rolling the foot from heel to toe the angle formed by the magnets is reduced. The magnetic field has a damping effect on the rolling process. Vertically inserted magnets (b) produce the same cushioning effect by corresponding guides. The magnets can be replaced by cushioning elements such as helical springs or air/gas pads held in devices. The leg prostheses of previous designs transmit the compressive effect occurring on placing the foot on to the ground to a considerable part of the human skeleton, and this may result in damage due to continual loading. The cushioning is intended to relieve the loaded parts of the skeleton. <IMAGE>

Dämpfung Pi'ir BßinprothesenCushioning Pi'ir bony prostheses

Die Erfindung ergänzt die Patentanmeldung - Dämpfung für Stützen-. Sie bezieht sich auf die Anwendung von Magneten m , dis gleichpolig gegenüberliegend η durch din fflaqnstfelder f eine dämpfende Wirkung ergeben.The invention complements the patent application - damping for supports. It relates to the use of magnets m, dis homopolar opposite η through din fflaqnstfelder f a damping effect result.

die Magnete sind bei Anwendung (a) nach unten hin drehbar angeschlagen, sodaß durch die Iflaqnetfelder ,die wie ein Polster wirken,eine winklige l/orrichtunn entsteht. Bei Belastung durch Abrollen des FuOas u/ird der von dßn Magneten gebildete Uiinkel reduziert.Das Maonetfeld dämpft den l/nrgang des Abrollens.In application (a), the magnets are hinged so that they can be rotated downwards, so that an angular arrangement is created by the surface fields, which act like a cushion. When the foot is unrolled, the angle formed by the magnet is reduced. The Maonet field dampens the unwinding process.

Vertikal eingebaute 'fiagnete (b) bewirken, durch fintsprechende Führungen gehalten, den gleichen dämpfenden Effekt.Vertically built-in 'fiagnete (b) effect through fint-speaking guides kept the same dampening effect.

Anstelle der Magnete können andere dämpfende Elemente wie Schraubenfedern treten, oder die Dämpfung kann durch ein in entsprechender Vorrichtung gehaltenns Luft - oder Gaspolster bewirkt werden. Prothesen, wie sie als Beinprothassn Verwendung finden,übermitteln dia Wucht und die Stnuchwirkung,die beim Aufsetzen auf den Boden entsteh t ,auf einen wes-ientlichnn Teil des Skeletts. Schaden durch dip Dauerbslastung können die Folqe sein. Durch die Dämpfung soll eine Entlastung der beanspruchten Skelattpartien erreicht werden.Instead of magnets, other damping elements such as coil springs can be used or the dampening can be effected by an air or gas cushion held in a suitable device. Transmit prostheses as they are used as leg prostheses dia force and the stump effect when it touches the ground arises on an essential part of the skeleton. Damage from dip exposure can be the consequence. The damping is intended to relieve the stressed skeleton areas can be achieved.
