Anm. Firma Wilhelm Julius !Teufel, 7 Stuttgart, Seckarstr.189Note: Wilhelm Julius! Teufel, 7 Stuttgart, Seckarstrasse 189 Gelenkfestlegung für orthopädische Apparate«Joint definition for orthopedic appliances "

Die Erfindung betrifft eine Gelenkfeetlegung für orthopädische Apparate (jjähmungsapparate). Dies· Gelenkfeatlegungen erfolgen durch Stifte und Eaeten oder durch in Voraprüngen. an den Gelenkteilen einschwenkbare Sperrglieder· Diese im Abstand von der Gelenkachse an den scheibenartigen Gelenkteilen der Apparateteile liegenden Sperren sind oft starker Beanspruchung ausgesetzt und unterliegen einem grossen Tersohleiss ο Die Sicherheit der Sperrung wird durch schnelles Ausschlagen der Sperrelemente und deren Lagerungen gefährdet; es kommt auoh xu unerwünschtem Bewegungsspiel der Gelenkteile gegeneinander·The invention relates to a joint ventilation for orthopedic apparatus (jjähmapparate). This · joint loosening are done by pins and Eaeten or by in Voraprüngen. locking elements that can be swiveled into the joint parts · These im Barriers located at a distance from the joint axis on the disk-like joint parts of the apparatus parts are often stronger Exposed to stress and are subject to a large crack in the sole ο The safety of the locking is increased by fast Knocking out of the locking elements and their bearings endangered; there is also xu undesirable play of movement of the joint parts against each other

Aufgabe der Erfindung ist es, diese Sachteile zu beseitigen und eine sichere und einfache Sperrung der Gelenkteile zu erhalten«The object of the invention is to eliminate these material parts and to secure and simple locking of the joint parts obtain"

Erfindungagemäss wird diese Aufgabe dadurch gelöst, dass der ron den Gelenkteilen im Abstand τοη der Gelenkaohse gebildete Sperrspalt fur den einsohwenkbaren Sperrkörper eine Tangente an den rom Sperrkörper beschriebenen Kreis bildet·According to the invention, this object is achieved in that the formed ron the joint parts at a distance τοη of the joint axle Locking gap for the Einohwenkbaren locking body a tangent forms the circle described on the rom locking body

Ein wichtiger Vorteil liegt darin, dass durch die Erfin-An important advantage is that the invention

drag ein Sperreyetea geschaffen ist, daa sich unter Belastung festzieht· Dies wird erstens dadurch bewirkt, dass durch den in Tangentenrichtung rerlaufenden Sperrspalt beispielsweise eine Einrastefeene in 30° leigung zur Horizontalen in der Strecklage des Apparates rorliegt. Sie Druckkraft, die durch diese Schrägung auf das Sperrelement ausgeübt wird, liegt in einest Winkel ron 90°zur Einrastebene. Ss entstehen Winkelrerhältnisse, die eine Kraftaufteilung ergeben, wodurch das Sperrelement in den Sperrschlitz gedrückt wird. Ein Herausrutschen unter Belastung wird unmöglich .drag a Sperreyetea is created sincea tightens under load · This is firstly caused by the fact that through the locking gap running in the tangent direction, for example, a locking gap at a 30 ° inclination to the horizontal in the extended position of the apparatus ror lies. The compressive force that is exerted on the locking element by this inclination is at an angle of 90 ° to the locking plane. This creates angle ratios that distribute forces result, whereby the locking element is pressed into the locking slot. Slipping out under load becomes impossible.

Ein zweites Merkmal der Erfindung besteht darin, dass der Schwenkpunkt des Sperrkörpers an dem einen Gelenkteil so liegt, dass eine durch den Schwenkpunkt und Sperrkörper rerlaufende Linie bei eingerasteter Sperre mit der Einrastebene einen Winkel ran fiber 90° bildet. Hierdurch wird erfindungsgemäss der Torteil einer zusätzlichen Sicherung der Sperrlage erreicht, weil das über die labile Stellung bewegte, eingerückte Sperrglied nach Art eines Kniekbesels wirkt·A second feature of the invention is that the pivot point of the locking body at which is located a hinge portion so that a rerlaufende through the pivot point and line blocking body in the engaged lock ran with the Einrastebene forms an angle 90 degrees fiber. In this way, according to the invention, the gate part of an additional securing of the locking position is achieved because the indented locking member moved over the unstable position acts like a knee-joint.

Erfindungsgemäss.wird der Sperrkörper walzenförmig ausgebildet und der Sperrspalt durchlaufend in einem Gabelkopfgelenk ausgebildet. Der Sperrkörper wird so ren allen zusätzlichen Belastungen befreit und ausschliesslich auf Abscherung beansprucht. Erfmndungsgemäss wird so auch die Schwenklagerung des Sperrgliedes roll entlastet·According to the invention, the locking body is designed in the shape of a cylinder and the locking gap is designed continuously in a fork joint. The locking body is relieved of all additional loads and only subjected to shearing. According to the invention, the Pivot bearing of the locking member roll relieved

In der Zeichnung ist die Gelenkfestlegung der Erfindung beispielsweise veranschaulicht. Es zeigernIn the drawing is the joint definition of the invention for example illustrated. Show it

Fig.1 in teilweisen Schnitt die Gelenkfestlegung für ein Kniegelenk in der Sperrlage,1 shows, in partial section, the joint definition for a knee joint in the blocked position,

Fig.2 das Kniegelenk der Fig.1 mit ausgerücktes Sperrkörperm Fig.3 eine Seitenansicht der Fig.1 im Schnitt A-B der Fig.1.Fig.2 shows the knee joint of Fig.1 with the locking body disengaged 3 shows a side view of FIG. 1 in section A-B of FIG.

Die pcheibenartigen Gelenketücke 1,2 an der Obersohenkelschiene 3 und der Unterschenkelschiene 4 sind durch die Gelenkachse 5 rerbunden. Sie Gelenkteile 1 und 2 bilden einen durchlaufenden Sperrspalt 6· Der Sperrspalt 6 rerlauft in der Richtung eines Kreistangente, die durch die strichpunktierte Linie angedeutet ist. Diese Kreistangente 7 bildet in der gezeichneten Strecklage der Teile beispielsweise eine Neigung Ton 00° rar Horizontalen. Der den walzenförmigen Sperrkörper 6 tragende Spevfrhebel 9 ist um die Achse an der Oberschenkelschieme 3 aölnvmltbfi?» Wie aus Fig.3 ersichtlich ist, bildet die Unterschenkelacbiene 4- einen gabelförmigen Gelenkteil 2.The disc-like joint pieces 1, 2 on the thigh splint 3 and the lower leg splint 4 are connected by the hinge axis 5. Joint parts 1 and 2 form one Continuous blocking gap 6 · The blocking gap 6 runs in the direction of a circle tangent, which is indicated by the dash-dotted line. This circle tangent 7 forms in the drawn extended position of the parts, for example, an inclination tone 00 ° rar horizontals. The spevr lever 9 carrying the roller-shaped locking body 6 is around the axis on the thigh strap 3 aölnvmltbfi? » As can be seen from FIG. 3, the lower leg acbiene 4- forms a fork-shaped joint part 2.

In der in Fig.1 gezeigten Stellung ist der walzenförmige Sperrkörper,8 mit dem durchlaufenden Sperrspalt 6 in Eingriff und die Gelenkteile sind gegeneinander unbeweglichIn the position shown in Figure 1 is the cylindrical Locking body, 8 with the continuous locking gap 6 in engagement and the joint parts are immovable with respect to one another festgelegt.set.

In der Darstellung nach Fip.2 ist der Sperrkörper 8 ausaer Eingriff mit dem Sperrschlitz 6. Die Gelenkteile sind gegeneinander frei beweglich.In the illustration according to Fig. 2, the locking body 8 is ausaer Engagement with the locking slot 6. The joint parts can move freely with respect to one another.
