Description

Laubsägebogenspanner. Die Erfindung besteht in einer Vorrichtung, welche das lästige Zusammendrücken des Laubsägebogens beim Einspannen von Laubsägen vereinfachen soll.Fret saw clamp. The invention consists in a device which the annoying pressing together of the fretsaw arch when clamping fretsaws should simplify.

Die Zeichnung stellt den Gegenstand der Erfindung dar. Abb. i zeigt die Aufsicht; Abb. a zeigt die Seitenansicht der Vorrichtung; _Abb. 3 zeigt eine Einzelheit der Vorrichtung.The drawing represents the subject of the invention. Fig. I shows the supervision; Fig. A shows the side view of the device; _Fig. 3 shows a Device detail.

Der Erfindungsgegenstand besteht aüs zwei Haken a und b, die mit ihren umgebogenen Enden um die Laubsägebogenschenkel gelegt werden und an den anderen Enden mittels eines drehbar um die Zapfes h gelagerten Griffes c nach zwei Richtungen bewegt werden können. Wird der Hebel c in Pfeilrichtung bewegt, so werden beide Laubsägebogenschenkel zusammengedrückt. Damit nun die Schenkel in dieser Lage verbleiben, ist um den einen Zapfen h ein ,drehbar gelagerter Zahnsegtnenthebel d angebracht, welcher mit seinen Zähnen hinter die Klinke f zu liegen kommt und somit die Spannung der Laubsägebogenscienkel aufnimmt. Eine Feder e sorgt dafür, daß .der Segmenthebel, d immer gegen den Schnepper f gedrückt wird. Um ein seitliches Ausweichen der Feder e und des Hebels d zu vermeiden, ist über beide eine Kappe g angebracht. Soll nun, nachdem die Laubsäge bequem eingespannt worden ist, die Vorrichtung entfernt werden, so braucht man nur den Hebel d nach oben zu drücken. Da man mit dieser Vorrichtung immerhin mehrere Größen von Laubsägebogen spannen kann, ist es aber auch möglich, durch Verlängerung des Haltens a, an dem mehrere Löcher angebracht werden und anstatt des Zapfens oder Nietes h eine :Schraube verwandt wird, für jede Größe diese Vorrichtung gebrauchen zu können.The subject matter of the invention consists of two hooks a and b, with their bent ends are placed around the jigsaw bow legs and on the other Ends by means of a handle c rotatably mounted around the pin h in two directions can be moved. If the lever c is moved in the direction of the arrow, both Jigsaw legs pressed together. So that the legs now remain in this position, is attached to the one pin h a, rotatably mounted toothed segregation lever d, which comes to rest with its teeth behind the pawl f and thus the tension the jigsaw handle picks up. A spring e ensures that .the segment lever, d is always pressed against the snap f. A sideways evasion of the spring To avoid e and lever d, a cap g is attached over both of them. Should now after the fretsaw has been comfortably clamped, the device can be removed, you only need to push lever d upwards. As one with this device can span several sizes of fretsaw, but it is also possible by extending the holding a, to which several holes are made and instead of the tenon or rivet h a: screw is used for each size this device to be able to use.
