Description

Ernst Pohl in Kiel Innenschiene für Röhrenknochen Zusatz zum Patent 742097 Gemäß vorliegender Erfindung wird die im Hauptpatent vorgesehene Querfederung der Schiene dadurch erreicht, daß die Schiene rinnenförmig mit federndem Rücken ausgebildet ist. Die Zeichnung stellt einige Ausführungsbeispiele dar. Ernst Pohl in Kiel Inner splint for long bones Addition to the patent 742097 According to the present invention, the transverse suspension provided in the main patent the rail is achieved in that the rail is shaped like a channel with a resilient back is trained. The drawing shows some exemplary embodiments.

Bei der Ausführungsform gemäß Fig. I ist die Schiene aus einem dünnwandigen Rohr entstanden zu denken, dessen Wand in Längsrichtung durch einen Walzvorgang o. dgl. von der einen Seite eingebeult wurde, so daß zwei einander gegenüberliegende Wandstellen miteinander in Berührung stehen oder einander dicht gegenüberliegen, während zu beiden Seiten davon hohle Ränder gebildet sind. In the embodiment according to FIG. I, the rail is made of a thin-walled one To think of a tube, its wall was created in the longitudinal direction by a rolling process o. The like. Was dented from one side, so that two opposite one another Wall parts are in contact with each other or are close to each other, while hollow rims are formed on both sides thereof.

Diese Schiene ist im Querprofil dadurch elastisch verformbar, daß der durch das tiefe Eindrücken der einen Rohrwandseite gebildete verdoppelte Rücken einer Querbeanspruchung durch Druck auf die beiden verhältnismäßig steifen Hohlränder federnd nachgibt.This rail is elastically deformable in the transverse profile in that the doubled back formed by the deep indentation of one side of the pipe wall a transverse stress due to pressure on the two relatively stiff hollow edges resiliently yields.

Gemäß Fig. 2 ist ein ähnliches Ergebnis durch Biegen eines dünnen Streifens federnden Stoffes mit Einrollung der Längskanten erreicht. Referring to Fig. 2, a similar result is obtained by bending a thin one Stripe of resilient fabric achieved with curling of the long edges.

Das Schienenprofil der Fig. 3 ähnelt dem der Fig. I, von dem es sich in der Hauptsache insofern unterscheidet, als die Ränder so stark gegeneinander gebogen sind, daß zwischen ihnen nur ein verhältnismäßig schmaler Längsschlitz frei bleibt. The rail profile of Fig. 3 is similar to that of Fig. I, from which it is differs mainly in that the edges are so strongly against each other are bent that only a relatively narrow longitudinal slot is free between them remain.

Die dargestellten Schienen verfügen auch über eine gewisse elastische Biegsamkeit. The rails shown also have a certain elasticity Flexibility.

Schienen mit gleichwertigen, d. h. im Rücken federnden und an den Rändern verstärkten Profilen können auch durch Walzen, Pressen, Fräsen oder Ziehen hergestellt werden.Rails with equivalent, d. H. springy in the back and on the Edges reinforced profiles can also be made by rolling, pressing, milling or drawing getting produced.

PATENTANSPRCHE: I. Innenschiene für Röhrenknochen nach Patent 742 097, dadurch gekennzeichnet, daß sie rinnenförmig und in Querrichtung federnd gebogen ist. PATENT CLAIMS: I. Inner splint for long bones according to patent 742 097, characterized in that it is curved in the shape of a channel and resiliently in the transverse direction is.
