Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Apparate.Apparatus.

Gegenstand der Erfindung ist eine Vorrichtung zum Feststellen der Gelenke von künstlichen Gliedern und ähnlichen orthopädischen Apparaten.The invention relates to a device for fixing the joints of artificial ones Limbs and similar orthopedic appliances.

Erfindungsgemäß besteht das die Sperrung vermittelnde Zwischenglied aus einer mittels Exzenterhebels verschiebbaren Hilfsschiene, durch deren Bewegung das Ein- und Ausrücken der Sperrklinke gegenüber dem Sperrrad bewirkt wird.According to the invention, the intermediate member providing the locking consists of a means Eccentric lever displaceable auxiliary rail, the movement of which engages and disengages the pawl is effected opposite the ratchet wheel.

Auf der Zeichnung ist der Erfindungsgegenstand in Vorder- und Seitenansicht dargestellt. Im wesentlichen besteht die Vorrichtung aus einer Schiene a, die durch drei Führungsstifte b, c, d geführt ist und an deren oberem Ende eine exzentrische Lagerung e vorgesehen ist, welche durch den Hebel f zur Wirkung ■gebracht werden kann. Die hierbei verursachte Verschiebung der Schiene α nach unten veranlaßt einen Sperrzahn g, in den der jeweiligen Stellung des unteren Gelenkteiles h . entsprechenden Zahn des um die Achse I drehbaren Zahnrades i einzugreifen, wodurch die beiden Gelenkarme k und h in sicherer Weise zueinander festgelegt sind. . ■■ In the drawing, the subject of the invention is shown in front and side views. The device essentially consists of a rail a, which is guided by three guide pins b, c, d and at the upper end of which an eccentric bearing e is provided, which can be brought into effect by the lever f. The downward displacement of the rail α caused by this causes a ratchet tooth g, in which the respective position of the lower joint part h. to engage corresponding tooth of the gear wheel i rotatable about the axis I , whereby the two articulated arms k and h are fixed to one another in a secure manner. . ■■

Die Anzahl der Führungsstifte kann nach Bedarf vermehrt werden, so daß die Schiene a auch bei ganz geringen Dimensionen nie ihre Form verändern kann.The number of guide pins can be increased as required, so that the rail a can never change its shape even with very small dimensions.
