Description
LaubsägeFretsaw
Bei der Laubsäge nach dem Hauptpatent und ebenso bei den bekannten Laubsägen mit geraden Schlitzen, in die die verstärkten Enden des Sägeblattes eingehängt werden, besteht noch die Gefahr eines Ausspringens des oberen Endes des Sägeblattes aus dem, Schlitz des Bügelendes, wenn die Säge nach aufwärts geführt wird. Um ein solches' Herausspringen zu verhüten, werden erfindungsgemäß die senkrechten Schlitze der Bügelenden nur bis zur halben Höhe in Richtung gegeneinander verjüngt ausgeführt, und diese Verjüngung vertieft sich an beiden Enden von vorwärts nach rückwärts. Das Sägeblatt wird dadurch zwangsläufig in Richtung der in der rückwärtigen Schlitzverengung anliegenden Stellung gehalten, und ein Herausspringen desselben nach vorn ist nicht mehr möglich. Außerdem erhalten die Flächen der Sägeblattenden in dem gleichbleibenden Teil der Schlitzhöhe vermehrten seitlichen, Halt.With the fretsaw according to the main patent and also with the well-known fretsaws straight slots into which the reinforced ends of the saw blade are hung nor the risk of the upper end of the saw blade jumping out of the, Slit at the end of the temple when the saw is moved upwards. To such a 'jumping out to prevent, according to the invention, the vertical slots of the temple ends only run up to half the height in the direction of each other tapered, and this Taper deepens from forward to backward at both ends. The saw blade will thereby inevitably in the direction of the adjacent slit constriction in the rear Hold position, and jumping out of the same forward is no longer possible. In addition, the surfaces of the saw blade ends in the constant part of the slot height have increased lateral, Stop.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, und zwar zeigen: The drawing shows an embodiment of the invention, namely show:
Abb. ι den Laubsägebügel in Seitenansicht, Abb. 2 das obere Bügelende von vorn,Fig. Ι the fretsaw in side view, Fig. 2 the upper end of the bow from the front,
Abb. 3 das untere Bügelende von der Seite gesehen.Fig. 3 the lower end of the temple seen from the side.
Der senkrechte Schlitz 1 ist hier nicht auf der ganzen Höhe ,des Querschnittes des Laubsägebügels nach unten verjüngt zulaufend gestaltet, sondern, wie Abb. 2 zeigt, nur auf die halbe Höhe des Querschnittes; die Wände des unteren Schlitzteiles verlaufen parallel zum eingespannten Sägeblatt. An dem unteren Bügelende, das nicht besonders dargestellt ist, ist es umgekehrt. Außerdem ist die Verjüngung, wie Abb. 1 erkennen läßt, an beiden Bügelenden von vorwärts nach rückwärts vertieft. Die Ausbildung des unteren Bügelendes läßt Abb. 3 erkennen. Bei dieser Ausführung ist ein Herausspringen des Sägeblattes nicht mehr möglich.The vertical slot 1 is not here all the way up, the cross-section of the jigsaw tapered downwards, but, as Fig. 2 shows, only to half the height of the cross-section; the walls of the lower part of the slot run parallel to the clamped saw blade. At the lower end of the temple, that is not specifically shown, it is the other way around. In addition, the rejuvenation, As shown in Fig. 1, deepened at both temple ends from forwards to backwards. The formation of the lower end of the temple can be seen in Fig. 3. In this version it is no longer possible for the saw blade to jump out.
