Description

Künstlicher Fuß aus Gummi o. dgl. mit eingelegtem Hohlkern aus lnetall Die Erfindung betrifft einen künstlichen Fuß aus Gummi o. dgl. mit eingelegtem Hohlkern aus Metall, welcher zum Befestigen des Fußes an dem künstlichen Bein dient. Es hat sich gezeigt, daß eine einwandfreie Befestigung des Gummis an dem metallenen Hohlkern Schwierigkeiten macht. Weichgummi und Metall verbinden sich nur unvollkommen miteinander, und es findet infolgedessen an den am stärksten beanspruchten Stellen eine Lösung des Gummis von dein Metallkern statt.Artificial foot made of rubber or the like with an inlaid hollow core made of metal The invention relates to an artificial foot made of rubber or the like with an inserted hollow core made of metal, which is used to attach the foot to the artificial leg. It has has been shown that a proper attachment of the rubber to the metal hollow core Makes trouble. Soft rubber and metal combine only imperfectly, and as a result it finds a solution in the most stressed areas of the rubber held by your metal core.

Gemäß der Erfindung wird dieser Übelstand dadurch beseitigt, daß die Außenfläche des Metallkerns mindestens an den am meisten beanspruchten Stellen, insbesondere der Spitze und dem Hackenteil, finit einem anvulkanisierten Hartgummiüberzug bedeckt ist. Dieser Hartgummiüberzug hat den Vorteil, daß er beim Vulkanisieren sich fest mit dein Metall verbindet und auch eine feste Verbindung mit dem Weichgummi eingeht. Um ein besseres Haften des Hartgummis an dein Kern zu erreichen, wird der letztere mit siebartig angeordneten Durchbohrungen oder auch mit Schlitzen versehen, in welche der aufgebrachte Gummi vor der Vulkanisation eingedrückt wird.According to the invention, this drawback is eliminated in that the Outer surface of the metal core at least in the most stressed areas, in particular the tip and the heel part, finite a vulcanized hard rubber coating is covered. This hard rubber cover has the advantage that it is vulcanized firmly connects to your metal and also a firm connection to the soft rubber comes in. In order to achieve better adhesion of the hard rubber to your core, the the latter with perforations arranged like a sieve or with slots, into which the applied rubber is pressed before vulcanization.

Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise dargestellt., und zwar ist Abb. i ein Längsschnitt durch ein künstliches Bein gemäß der Erfindung und Abb. 2 ein Schnitt durch Abb. i in Richtung der Linie Es ist a die Hülse eines künstlichen Beines, welche aus Metall, vorzugsweise aus einem geeigneten Leichtmetall, z. B. einer Aluminiumlegierung, hergestellt ist. In diese Hülse ist in an sich bekannter Weise ein Trichter b eingesetzt, welcher den Stumpf umfaßt und beispielsweise aus Kautschuk hergestellt sein kann. Der Fuß des künstlichen Beines besteht aus einem Hohlkern c aus Metall, vorzugsweise wieder Leichtmetall. Dieser Kern ist an der Stelle d mit der Beinhülse verbunden, z..B. durch Anschweißen, Anlöten, Vernieten o. dgl. Er kann aber auch mit der Beinhülse aus einem Stück bestehen.The drawing shows an embodiment of the subject matter of the invention shown for example., namely Fig. i is a longitudinal section through an artificial Leg according to the invention and Fig. 2 is a section through Fig. I in the direction of the line It is a the sleeve of an artificial leg, which is made of metal, preferably made of a suitable light metal, e.g. B. an aluminum alloy is made. In this sleeve, a funnel b is used in a known manner, which includes the stump and can be made of rubber, for example. The foot the artificial leg consists of a hollow core c made of metal, preferably again Light metal. This core is connected to the leg sleeve at point d, z..B. by welding, soldering, riveting or the like. But it can also be done with the leg sleeve consist of one piece.

Der Kern c ist an seiner Spitze e und an dein Hackenteil f siebartig durchlöchert. Die beiden Teile e und f sind am Boden durch einen Schlitz ä miteinander verbunden. Um diesen so vorbereiteten Hohlkern c ist eine Schicht lt aus Hartgummi herumgelegt. Durch die Anordnung der Löcher und Öffnungen wird eine gute Bindung der Hartkautschlikschicht mit dein Leichtmetall erzielt. An der Hartguinmischicht bzw. dein übrigen Teil des Kernes ist dann der eigentliche Fuß i aus Weichgummi angebracht. Die Herstellung der Hartgummischicht bzw. des Fußes i geschieht in der in der Gummiverarbeitung üblichen Weise.The core c is sieve-like at its tip e and at your heel part f perforated. The two parts e and f are connected to each other at the bottom through a slot tied together. Around this hollow core c prepared in this way is a layer lt made of hard rubber lying around. The arrangement of the holes and openings creates a good bond the hard rubber layer achieved with your light metal. At the hard guinea layer or your remaining part of the core is then the actual foot i made of soft rubber appropriate. The production of the hard rubber layer or the foot i takes place in the customary in rubber processing.

Da gerade die Spitze und der Hackenteil des Fußes am meisten beansprucht werden, erhöht die Hartgummischicht die Lebensdauer des Fußes, da einerseits die Hartgummischicht fest an dem Kern und anderseits der Weichgummi fest an dein Hartgummi haftet.Since the tip and the heel part of the foot are the most stressed the hard rubber layer increases the lifespan of the foot, since on the one hand the Hard rubber layer stuck to the core and on the other hand the soft rubber stuck to your hard rubber adheres.

An Stelle von Gummi kann natürlich auch ein ähnlicher Ersatzstoff treten.Instead of rubber, a similar substitute can of course also be used step.
