Description
Werkzeug zum Strecken von Kniehebelspreizen aus zwei nebeneinanderliegenden Flach- oder Winkeleisen Die bekannten Kniehebelspreizen aus zwei nebeneinanderliegenden Flach- oder Winkeleisen können leicht über die Strecklage hinaus einknicken, weil der eine Hebel am anderen keinen Anschlag findet. Die. Erfindung betrifft ein Werkzeug zum Strecken derartiger Kniehebelspreizen, das zugleichein Einknicken der Spreizen über die Strecklage hinaus verhindert.Tool for stretching knee lever spreaders from two adjacent ones Flat or angle iron The well-known toggle lever spreaders made up of two adjacent ones Flat or angle irons can easily buckle beyond the extended position because one lever does not find a stop on the other. The. Invention relates to a tool for stretching such toggle spreaders, which at the same time buckle the spreaders prevented beyond the extended position.
Die Zeichnung zeigt ein Ausführungsbeispjel des Erfindungsgegenstandes im ' Gehräuch, und zwar vor und in der Strecklage der Kniehebel (Abb. i und 2, Seitenansicht).The drawing shows an exemplary embodiment of the subject matter of the invention in the ear, namely in front of and in the extended position of the toggle levers (Fig. i and 2, side view).
Abb.3 ist eine Draufsicht auf das Werkzeug, teilweise im Schnitt.Figure 3 is a top plan view of the tool, partly in section.
Die dargestellte Kniehebelspreize besitzt zwei nebeneinanderliegende und um einen verstellbaren Bolzen 3 drehbare Winkeleisen i und 2. Dieselben sind durch Bolzen q. je mit einem Schuh 5 gelenkig verbunden. 6 sind die Ringe, die über die in der Strecklage befindlichen Hebel 1, 2 geschoben werden können (Abb.2).The toggle clamp shown has two adjacent ones and angle irons i and 2 rotatable about an adjustable bolt 3 are the same by bolts q. each articulated with a shoe 5. 6 are the rings that are over the levers 1, 2 in the extended position can be pushed (Fig.2).
Das Werkzeug zum Strecken der Spreize besitzt einen Hebel 12 mit drei Armen a, b, c. Am Arm c greift eine Handhabe 16 an; der Arm a hat einen Bolzen 13 und der Arm b einen Bolzen 14, der mit einem winklig zu ihm stehenden Anschlag 15 versehen ist (Abb. 3). Dieses Werkzeug wird so auf die Hebel 1, 2, welche sich in der StelIgng nach Abb. i befinden, gesetzt, daß die Bolzen 13, 1 ¢ die Flacheisen 1, 2 und 3 oben und unten erfassen. Dann wird der Handhebel 16 in der in Abb. a angegebenen Pfeilrichtung bewegt.. Hierdurch werden die Flacheisen i und 2 in die Strecklage nach Abb.2 gebracht. Dabei bildet der Bolzen 13 ein Druckorgan für das Flacheisen 2 und gleichzeitig einen Anschlag für das Flacheisen i, so daß beide Flacheisen ohne besondere Sorgfalt in die genaue Strecklage kommen, während der die Schieisen umfassende Ansatz 15 am Bolzen 1 ¢ das Abgleiten des Hebels 12. verhindert.The tool for stretching the spreader has a lever 12 with three arms a, b, c. A handle 16 engages the arm c; arm a has a bolt 13 and arm b has a bolt 14 which is provided with a stop 15 at an angle to it (Fig. 3). This tool is so placed on the levers 1, 2, which are in the position according to Fig. I, that the bolts 13, 1 [cover the flat bars 1, 2 and 3 above and below. Then the hand lever 16 is moved in the direction of the arrow indicated in Fig. A. This brings the flat irons i and 2 into the extended position according to Fig.2. The bolt 13 forms a pressure element for the flat iron 2 and at the same time a stop for the flat iron i, so that both flat irons come into the exact extended position without special care, while the extension 15 on the bolt 1 ¢ the sliding of the lever 12. prevented.
