Description

Der Ratschenhebel nach dem Patent 820 276 besitzt einen mit der Schaltklinke fest verbundenen Hand,hebel, der in einem das mit einer Ratschenverzahnung ausgestattete Schaltrad tragenden Lagerkörper federbelastet verschieb- und drehbar gelagert ist. Manchmal ist zum Anziehen oder Lösen nur ein -kurzes Hinundherschwenken des Hebels erforderlich.The ratchet lever according to patent 820 276 has a hand lever which is firmly connected to the pawl and which is spring-loaded displaceably and rotatably mounted in a bearing body carrying the ratchet toothing equipped with a ratchet gear. Sometimes all that is needed to tighten or loosen is a quick rocking of the lever.

Um nun den Ratschenhebel auch als starren Hebel verwenden zu können, ist der die Scha-Itklinke tragende Bolzen gemäß der zusätzlichen Erfindung ersetzbar durch einen Bolzen, dessen Kopf in die Ratschenverzahnung formschlüssig eingreift, In der Zeichnung ist die weitere Ausbildung des Hebels in den Fig. i und 2 in zwei verschiedenen Seitenansichten dargestellt.In order to be able to use the ratchet lever as a rigid lever, the bolt carrying the pawl can be replaced according to the additional invention by means of a bolt, the head of which engages positively in the ratchet toothing, In the drawing, the further design of the lever in FIGS. I and 2 is in two different side views.

Der Handgriff 6, der gegenüber dem Lagerkörper 2 für das Schaltrad i i und unter Zusammendrücken einer Druckschraubenfeder 8 axial verschiebbar und dann drehbar angeordnet ist, trägt einen Bolzen 5, der mit ihm durch einen Niet 7 fest verbunden ist. Auf diesem Bolzen 5 ist die Druckschraubenf eder 8 innerhalb des Lagerkörpers :2 angeordnet. Durch die Feder 8 ist der Bolzen 5 mit seinem Kopf 5' gegen das S dhaltrad i i drückbar.The handle 6, which is axially displaceable and then rotatable with respect to the bearing body 2 for the ratchet wheel ii and under compression of a compression coil spring 8 , carries a bolt 5 which is firmly connected to it by a rivet 7. On this bolt 5 , the compression coil spring 8 is arranged within the bearing body: 2. By the spring 8 , the bolt 5 with its head 5 'can be pressed against the S dhaltrad ii.

Im gez - eichneten-Beispiel paßt der Bolzenkopf 5' formschlüssig in eine Lücke i i` der Verzahnung der Schaltscheibe i i, so daß bei dem Hinundherbewegen des Hebels 6 die Schaltscheibe i i sofort formschlüssig mitgenommen wird. Nach dem Auswechseln des Bolzens 5, 5» gegen den ent ' sprechenden Bolzen nach dem Hauptpatent ist der Hebel wieder als Ratschenhebel verwendbar.In signed - calibration Neten example, the bolt head fits 5 'form-fitting manner into a gap II` the toothing of the indexing disk ii, so that in the Hinundherbewegen of the lever 6, the switching disk ii is taken immediately form-fitting manner. After replacing the bolt 5, 5 'against the ent' speaking bolts according to the main patent, the lever is reusable as a ratchet lever.

Man kann den Kopf 5' auch als Teil für sich ausbilden, das bei zurückgezogener Schaltklinke auf diese Schaltklinke aufsetzbar oder aufsteckbar ist. Die Schaltklinke greift dann mit ihrem Zahn in eine Ausnehmung des Kopfes ein, welcher seinerseits forrnschlüssig in eine Lücke der Ratschenverzahnung eingreift, Dieser aufsetzbare Kopf kann auch mit einem oder zwei kleinen Stiften versehen sein, die ihn in entsprechenden Bohrungen der Schaltklinke sichern. - The head 5 'can also be designed as a part that can be placed or slipped onto this pawl when the pawl is retracted. The pawl then engages with its tooth in a recess of the head, which in turn positively engages in a gap in the ratchet toothing. This attachable head can also be provided with one or two small pins that secure it in corresponding holes in the pawl. -
