Description

Handsäge mit Kraftantrieb. Die motorisch angetriebene Handsäge nach der vorliegenden Erfindung gehört zu jener Gattung von Sägen, bei der ein Gestell einen Motor und ein Vorgelege uinfaßt, durch welches der Säge eine Hinundherbewegung in Führungen des Gestelles erteilt wird. Das Neuartige am Erfindungsgegenstand ist darin zu sehen, daß sich die Führung für den Rükken des Sägeblattes über die ganze Länge der Säge hin erstreckt, während die Seitenführungen sich quer über die ganze Breite des Sägeblattes und zu beiden Seiten desselben erstrecken, so daß das ungespannte Sägeblatt sicher geführt ist und bei größter Beanspruchung sich nicht durchbiegt.Hand saw with power drive. The motor-driven hand saw after of the present invention belongs to that class of saws in which a frame a motor and a reduction gear by which the saw reciprocates is issued in guides of the frame. What is new about the subject of the invention is to see that the guide for the back of the saw blade over the whole Length of the saw extends out, while the side guides extend across the whole Width of the saw blade and extend it on both sides, so that the unstressed The saw blade is securely guided and does not sag under heavy loads.

Ein Ausführungsbeispiel ist dargestellt. Abb. i ist eine Draufsicht, Abb: z eine Seitenansicht und Abb.3 eine Endansicht der Säge. .An exemplary embodiment is shown. Fig. I is a top view, Fig: z is a side view and Fig. 3 is an end view of the saw. .

Das nahezu rechteckige Gestell i setzt sich in einer oberen Leiste 2 fort, die als Führung für den Rücken des Sägeblattes 4 dient. Zu diesem Zweck ist die Leiste 2 bei 3 mit einer entsprechenden Nut für den Rük-.ken des Sägeblattes 4. versehen.The almost rectangular frame i sits in an upper bar 2, which serves as a guide for the back of the saw blade 4. To this end is the bar 2 at 3 with a corresponding groove for the back .ken of the saw blade 4. provided.

Der am Gestell i angebrachte Motor 5 treibt das Vorgelege 6, 7, von welchem aus unter Vermittlung der Kurbelwelle B. und der Kurbelstange g das Sägeblatt hin und her geschoben wird, da däs eine Ende der Kurbelstange 9 an das rückwärtige. Ende des .Sä.geblattes angeschlossen ist.The motor 5 attached to the frame i drives the countershaft 6, 7, of which, through the intermediary of the crankshaft B. and the connecting rod g, the saw blade is pushed back and forth, since one end of the connecting rod 9 to the rear. The end of the saw blade is connected.

Das Vorgelege wird auf beiden Seiten durch abnehmbare Deckel 13 abgeschlossen, die sich von der oberen Kante des Gestelles i bis zur unteren Kante hin erstrecken und die demnach ungefähr ebenso breit sind wie das Sägeblatt 4. Die untere Kante dieser Deckel 13 ist an einen Leistenteil angelenkt, dessen Abstand vom Führungsteil 2 für den Rücken der Säge ungefähr der Breite des Sägeblattes entspricht. Die am Gestell angeordneten Seitenführungen (Streben) erstrecken sich quer über die ganze Breite, des Sägeblattes.The lay-up is closed on both sides by removable covers 13 , which extend from the upper edge of the frame i to the lower edge and which are therefore approximately as wide as the saw blade 4. The lower edge of this cover 13 is hinged to a strip part whose distance from the guide part 2 for the back of the saw corresponds approximately to the width of the saw blade. The side guides (struts) arranged on the frame extend across the entire width of the saw blade.
