Description

Verriegelbares Kniegelenk für künstliche Beine. Die Erfindung betrifft ein verriegelbares Kniegelenk für künstliche Beine und besteht darin, daß die Stelze dies künstlichen Beines nach Anheben eines Hebels im Winkel zur 1VIetallkappedes Beines gebogen wer-den kann und unter Wirkung einer Feder selbsttätig in der Strecklage wieder verriegelt wird.Lockable knee joint for artificial legs. The invention relates to a lockable knee joint for artificial legs and consists in that the stilt this artificial leg after lifting a lever at an angle to the metal cap The leg can be bent and automatically in the extended position under the action of a spring is locked again.

Bei den bekannt gewordenen Kniegelenken dieser Art wird, die Stelze in der Blechkapsel durch einen Ring gehalten und greift in eine Aussparung einer um den Drehzapfen angeordneten Hülse ein. Zwischen dieser Hülse und dem mit der Blechkapsel zusammenarbeitenden Ring ist eine Druckfeder angeordnet. Ein an diametral gegenüberliegenden Punkten des Ringes angreifender Bügel erstreckt sich über einen an der Metallkappe drehbar gelagerten Hebel, der zwecks Biegens des Gelenkes von Hand angehoben wird.The knee joints of this type that have become known are the stilts held in the sheet metal capsule by a ring and engages in a recess of a a sleeve arranged around the pivot pin. Between this sleeve and the one with the Sheet metal capsule cooperating ring is arranged a compression spring. One at diametrical opposite points of the ring engaging bracket extends over a on the metal cap rotatably mounted lever, which for the purpose of bending the joint of Hand is raised.

Der Zweck der E rfindung ist nun, ein Kniegelenk dieser Art zu schaffen, welches erheblich weniger Einzelteile aufweist und mithin in der Herstellung billiger und bei der Benutzung sicherer und zuverlässiger ist.The purpose of the E rfindung now is to create a knee joint of this type, which has considerably fewer parts and therefore in the production is safer and cheaper in use and more reliable.

Erreicht wird- dies'gemäß der Erfindung ,dadurch, daß dais obere Ende der Stelze als Lager zur Aufnahme des in Augen der Metallkappe des Beines befestigten Drehzapfens ausgebildet sowie mit einer Aussparung verse4.en ist, und mit dieser Aussparung ein unter Federwirkung stehender oberhalb des Lagers an der Meetallkappe drehbar angeordneter Hebel zusammenarbeitet.This is achieved, according to the invention, in that the upper end the stilt as a bearing for receiving the attached in eyes of the metal cap of the leg Trunnion is formed and verse4.en with a recess, and with this Recess a spring-loaded one above the bearing on the meeting cap rotatably arranged lever cooperates.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigt-Abb. i einen Längsschnitt durch das verriegelbare Kniegelenk gemäß der Erfindung und Abb.:2 eine schematische Seitenansicht. Die Stelze ii istoben unmittelbar als Lager 17 ausgebildet, in welchem der in den Augen 18 der Metallkappe it fest angebrachte Zapfen ig drehbar gelagert ist. An der Kappe it ist oberhalb 'des Lagers 17 bei :2o ein Hebe12i angelenkt, der unter Wirkung .einer ebenfalls an der Metallkappebefestigten Feder2.2 steht. Das Lager 17 ist mit einer Aussparung 2,3 versehen. In dieser Aussparung. 23 liegt für gewöhnlich der entsprechend ausgebildete Teil des Hebels 21. Das freie En,de:24 des Hebels 21 erstreckt sich durch einen Schlitz -der Metallkappe hindurch, so daß es von Handerfaßt: werden kann.In the drawing, an embodiment of the subject invention is shown, namely shows-Fig. i shows a longitudinal section through the lockable knee joint according to the invention and fig. 2 shows a schematic side view. The stilt ii is designed directly above as a bearing 17 in which the pin ig, which is firmly attached in the eyes 18 of the metal cap it, is rotatably mounted. On the cap it is above 'the bearing 17 at: 2o a Hebe12i articulated, which is under the action of a spring 2.2 also attached to the metal cap. The bearing 17 is provided with a recess 2, 3 . In this recess. 23 is usually the correspondingly designed part of the lever 21. The free end, de: 24 of the lever 21 extends through a slot in the metal cap so that it can be grasped by hand.

Die Wirkungsweise des Kniegelenkes ist folgende: Will die das künistliche Bein tragende Person eine sitzende Stellung einnehmen, so zieht sie durch Erfassen des En-des:24 den Hebel 21 nach eben, so daß -dieser Hebel außer Eingriff mit der Aussparung:23 des an dem oberen Teil der Stelze ausgebildeten Lagers 17 kommt. Nunmehr kann die Stelze i i mit Bezug auf die Metallkappe m im Winkel gebogen werden. Sobald die Stelze wieder in die Strecklage zur Metallkappe n kommt, greift der Hebel 21 selbsttätig unter Wirkung der Feder 22 wieder in die Aussparung 23 des Lagers 17 ein und verriegelt so das Gelenk in dier Strecklage.The mode of operation of the knee joint is as follows: If the person wearing the artificial leg wants to take a seated position, he pulls the lever 21 by grasping the end: 24 so that this lever is out of engagement with the recess: 23 of the the upper part of the stilt formed bearing 17 comes. The stilt ii can now be bent at an angle with respect to the metal cap m. Once the stilt comes back n in the extended position to the metal cap, engages the lever 21 automatically under the action of the spring 22 back into the recess 23 of the bearing 1 7 and thus locks the joint in commanding extended position.
