Abstract

The saw consists of a petrol or electric motor (8) with a handle/throttle (9)which is attached to a guide tube (5). The tube has a handgrip (6) and spring (7), which allows a branch etc. to be gripped by gripper arms (3) when relaxed. An inner tube (4) with a universal joint shaft drives a saw blade (1) which saws the branch off.

Description

Es ist bekannt, werden beispielsweise Bäume an Bundesstraßen ausgesägt, wird auf Hebebühnen und mit Motorkettensäge gearbeitet. Jedoch die abgesägten Baumäste könnten, für Menschen und Elektroleitungen, Gefahr bringen! Eine Motorgreifsäge bietet einen längeren Arm, hält den abgesägten Baumast fest und legt ihn sicher ab.It is known to be trees on federal highways, for example sawed out, is worked on lifting platforms and with a chainsaw. However, the sawn off tree branches could, for People and electrical lines, bring danger! A motorized gripping saw offers a longer arm and holds the sawn off Tree branch firmly and safely put it down.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Vielzahl von Motorgreifsägen für die jeweilige Anwendung zu vermindern.The invention specified in claim 1 is Problem underlying a variety of motor gripping saws for the to reduce the respective application.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This problem is caused by those listed in claim 1 Features resolved.

Die Vorteile, die durch die Erfindung erzielt werden:The advantages achieved by the invention:

Die nach Patentansprüche genannte Merkmale lakonisch, ein sauberes, schnelleres, sicheres und vielseitigeres Arbeiten an Bäumen, Sträuchern und Wurzeln etc.The features mentioned in patent claims laconic, a clean, faster, safer and more versatile Working on trees, shrubs and roots etc.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 2 angegeben. Eine Weiterbildung nach Patentanspruch 2 ermöglicht es eine geeignete Auswechslung der Säge zu treffen. Es ist anzustreben, Patentanspruch 1+2 zu kombinieren = Auswechslung des gesamten Sägekopfes.An advantageous embodiment of the invention is in the claim 2 specified. A training according to claim 2 allows a suitable replacement of the saw to meet. The aim is to claim 1 + 2 combine = replacement of the entire saw head.

Dadurch Anwendung in anderen Bereichen! Thereby application in other areas!  

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawing shown and is described in more detail below.

Es zeigtIt shows

Fig. 1 die Motorgreifsäge Fig. 1 the motor gripping saw

Fig. 2 bis Fig. 5 die Sägeköpfe. Fig. 2 to Fig. 5, the saw heads.

Die Motorgreifsäge Fig. 1 besteht aus (8) Benzin oder E=motor, aus (9) Gas+Haltegriff, (5) Führungsrohr, Haltegriff (6) mit Drehverschluß, (7) Druckfeder und dem inneren Rohr (4) mit Kardanwelle (2), es folgt der Sägekopf mit Sägeblatt (1), (3) Greifarme, (4a) Sägekopfverschluß und (10) Trageriemen.The motor gripping saw Fig. 1 consists of ( 8 ) petrol or E = motor, ( 9 ) gas + handle, ( 5 ) guide tube, handle ( 6 ) with rotary lock, ( 7 ) compression spring and the inner tube ( 4 ) with cardan shaft ( 2 ), followed by the saw head with saw blade ( 1 ), ( 3 ) gripper arms, ( 4 a) saw head lock and ( 10 ) carrying strap.

Die nach Patentanspruch 1 beschriebene Wirkungsweise.The mode of operation described according to claim 1.

Durch das Zusammendrücken, der Druckfeder zwischen Führungsrohr und Motor, gehen die Greifarme auseinander. Der Gegenstand wird gegriffen, durch Entspannen der Druckfeder. Die Greifarme drücken somit den Gegenstand an die Säge. Ist der Gegenstand durchsägt so wird er durch die speziellen Greifarme gehalten und zum Schluß abgelegt.By compressing the compression spring between the guide tube and motor, the gripper arms diverge. The object is gripped by relaxing the compression spring. The gripper arms press the object against the saw. If the object is sawed through, it becomes special Gripping arms held and finally put down.

Die nach Patentanspruch 2 beschriebene Wirkungsweise.The mode of operation described according to claim 2.

Durch die Drehvorrichtung am Haltegriff geht das Führungsrohr zurück, die Greifarme klappen auseinander. Es wird der Haltegriff zurückgedreht, so daß die Greifarme den Gegenstand (Baumast) greifen.The guide tube goes through the turning device on the handle back, the gripper arms fold apart. The handle is turned back so that the gripping arms Grab object (tree branch).

Durch Zusammendrücken der Druckfeder am Führungsrohr, wird der bewegliche Teil der Motorgreifsäge also Motor, inneres Rohr mit Kardanwelle (Kardangelenkwelle) und Sägeblatt gegen den Gegenstand gedrückt und durchsägt. Der abgesägte Gegenstand wird durch die Greifarme gehalten, abgelegt und gelöst!By compressing the compression spring on the guide tube, the Movable part of the motor gripping saw, i.e. motor, inner tube with Cardan shaft (cardan shaft) and saw blade against the object pressed and sawed through. The sawn-off object is held by the gripping arms, filed and solved!
