Abstract
Description
Die vorliegende Erfindung betrifft eine Säge, insbesondere eine manuell be tätigbare Säge.The present invention relates to a saw, in particular a manual operable saw.
Typische Sägen haben ein Sägeblatt, das mit einem Handgriff schwenkbar verbunden und relativ zu diesem verstellbar ist. Mit den üblichen Sägen lassen sich allerdings Zweige in höheren Bereichen eines Baumes nicht absägen.Typical saws have a saw blade that can be swiveled with one hand connected and adjustable relative to this. With the usual saws you can however, do not saw off branches in higher areas of a tree.
Durch die vorliegende Erfindung soll eine Säge geschaffen werden, mit der sich auch Zweige in höheren Bereichen von Bäumen absägen lassen.The present invention is intended to create a saw with which branches in higher areas can also be sawn off trees.
Die Erfindung sowie vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen definiert.The invention and advantageous embodiments of the invention are in the Defined claims.
Anhand der Zeichnungen wird ein Ausführungsbeispiel der Erfindung näher erläutert. Es zeigt:On the basis of the drawings, an embodiment of the invention is closer explained. It shows:
Fig. 1 eine Explosionsdarstellung einer Säge; Figure 1 is an exploded view of a saw.
Fig. 2 eine schematische Darstellung des Sägeblatt-Befestigungsmechanis mus; Fig. 2 is a schematic representation of the saw blade fastening mechanism;
Fig. 3 und 4 schematische Ansichten zum Veranschaulichen der Verbindung zwischen Sägeblatt und Handgriff. FIGS. 3 and 4 are schematic views for illustrating the connection between the saw blade and handle.
Die in den Fig. 1 bis 3 dargestellte Säge hat einen Handgriff 20 mit einem Schlitz 22, der an einem Ende vorgesehen ist und von zwei Rippen 24, 26 gebildet wird, die zur Aufnahme eines Sägeblatts 30 dienen. Die Rippe 26 hat eine kreis förmige Öffnung 28 (Fig. 2 und 3), die einen Schlitz 22 schneidet, um einen Zapfen 52 drehbar aufnehmen zu können. Die andere Rippe 24 hat ein Langloch 21. Der Zapfen 52 hat einen Kopf 521 zur Anlage an der Rippe 26 und ein Gegenge winde 522 zwecks Eingriff mit einem Außengewinde 54 einer Schraube 53. Die Stange 52 hat zwei Vorsprünge 523, die mit dem Langloch 21 der Rippe 24 in Ein griff bringbar sind, um den Zapfen 52 gegen eine Drehbewegung relativ zum Hand griff 20 zu sichern. Eine Feder 51 sitzt zwischen dem Kopf 521 des Zapfens 52 und der Rippe 26, um den Kopf 521 des Zapfens 52 von der Rippe 26 weg zu drücken, wie am besten in den Fig. 2 und 3 zu sehen ist.The saw shown in FIGS. 1 to 3 has a handle 20 with a slot 22 which is provided at one end and is formed by two ribs 24 , 26 which serve to receive a saw blade 30 . The rib 26 has a circular opening 28 ( Fig. 2 and 3) which cuts a slot 22 to receive a pin 52 rotatably. The other rib 24 has an elongated hole 21 . The pin 52 has a head 521 for abutment on the rib 26 and a counter thread 522 for engagement with an external thread 54 of a screw 53rd The rod 52 has two projections 523 , which can be brought into engagement with the elongated hole 21 of the rib 24 in order to secure the pin 52 against rotation relative to the hand 20 . A spring 51 sits between the head 521 of the pin 52 and the rib 26 to urge the head 521 of the pin 52 away from the rib 26 , as best seen in FIGS. 2 and 3.
Das Sägeblatt 30 hat eine längs verlaufende Nut 32, die von einem Ende 31 ausgeht und in einem Loch 34 endet, das an der Wurzel der Nut 32 gebildet ist und mit dieser in Verbindung steht. Die Breite der Nut 32 ist kleiner als der Außen durchmesser des Zapfens 52 zwecks Eingriff mit den Vorsprüngen 523 und der Schraube 53. Das Loch 34 hat einen Durchmesser, der nicht kleiner als der des Zap fens 52 ist, um den Zapfen 52 drehbar aufzunehmen. Das Ende 31 des Sägeblattes 30 hat einen Umfangsabschnitt mit einer oder mehreren Kerben 37. Ein Knopf 40 hat einen Mittelabschnitt, der mittels eines Stiftes 43 mit dem Handgriff 20 schwenkbar verbunden ist, und einen Sperrriegel 41, der an einem Ende gebildet ist, um mit irgendeiner der Kerben 37 in Eingriff zu gelangen. Eine Feder 42 sitzt zwi schen dem anderen Ende des Knopfes 40 und dem Handgriff 20, um den Sperrriegel 41 in Eingriff mit einer der Kerben 37 vorzuspannen und um das Sägeblatt 30 am Handgriff 20 in einer ausgewählten Winkelstellung festzulegen.The saw blade 30 has a longitudinal groove 32 which starts from one end 31 and ends in a hole 34 which is formed at the root of the groove 32 and is in communication therewith. The width of the groove 32 is smaller than the outer diameter of the pin 52 for engagement with the projections 523 and the screw 53 . The hole 34 has a diameter than that of the Zap fens 52 is not less to receive rotatable about the pin 52nd The end 31 of the saw blade 30 has a peripheral section with one or more notches 37 . A button 40 has a central portion pivotally connected to the handle 20 by a pin 43 and a locking bar 41 formed at one end to engage any of the notches 37 . A spring 42 sits between the other end of the knob 40 and the handle 20 to bias the locking bar 41 into engagement with one of the notches 37 and to fix the saw blade 30 on the handle 20 in a selected angular position.
Wenn die Schraube 53 in den Zapfen 52 vollständig eingeschraubt ist (Fig. 2), werden die Vorsprünge 523 des Zapfens 52 in Eingriff mit dem Langloch 21 gedrückt, so daß der Zapfen 52 gegen eine Drehbewegung relativ zu dem Handgriff 20 gesichert ist und die Schraube 53 aus dem Zapfen 52 herausgeschraubt werden kann. Wenn das Sägeblatt 30 mit dem Handgriff 20 verbunden und wieder von ihm gelöst werden soll, wird die Schraube 53 aus dem Zapfen 52 herausgeschraubt, bis die Vorsprünge 523 des Zapfens 52 aus dem Langloch 21 gelöst sind und in den Schlitz 22 des Handgriffs 20 greifen (Fig. 3). Das Sägeblatt 30 kann nun relativ zu dem Zapfen 52 bewegt werden, um die Vorsprünge 523 und/oder die Schraube 53 über die Nut 32 des Sägeblattes 30 mit dem Loch 34 in Eingriff zu bringen oder um die Vorsprünge 523 und/oder die Schraube 53 aus dem Loch 34 und der Nut 32 des Sägeblattes 30 zu lösen. Wenn der Sperrriegel 41 vorgespannt wird, um mit einer der Kerben 37 in Eingriff zu gelangen, wird das Sägeblatt 30 in einer entsprechen den Winkellage relativ zu dem Handgriff 20 eingestellt. When the screw 53 is fully screwed into the pin 52 ( Fig. 2), the projections 523 of the pin 52 are pressed into engagement with the elongated hole 21 , so that the pin 52 is secured against rotation relative to the handle 20 and the screw 53 can be screwed out of the pin 52 . If the saw blade 30 is to be connected to the handle 20 and to be released from it again, the screw 53 is unscrewed from the pin 52 until the projections 523 of the pin 52 are released from the elongated hole 21 and engage in the slot 22 of the handle 20 ( Fig. 3). The saw blade 30 can now be moved relative to the pin 52 in order to engage the projections 523 and / or the screw 53 with the hole 34 via the groove 32 of the saw blade 30 or to remove the projections 523 and / or the screw 53 to solve the hole 34 and the groove 32 of the saw blade 30 . When the locking bar 41 is biased to engage one of the notches 37 , the saw blade 30 is set in a corresponding angular position relative to the handle 20 .
Der Handgriff 20 hat ein Innengewinde 27 in dem Ende, das zu dem mit dem Schlitz 22 versehenen Ende entgegengesetzt ist. Eine Verlängerungsstange 70 ist an einem Ende mit einem Handgriff 71 und am anderen Ende mit einem Außenge winde 72 versehen, um mit dem Innengewinde 27 des Handgriffes 20 lösbar in Ein griff gebracht zu werden und um die Verlängerungsstange 70 mit dem Handgriff 20 lösbar zu verbinden, wodurch die Säge ohne zusätzliche Teile verlängert wird. Die Säge mit dem Sägeblatt 30 kann dann zum Schneiden bzw. Sägen von Zweigen in oberen Bereichen eines Baumes verwendet werden.The handle 20 has an internal thread 27 in the end which is opposite to the end provided with the slot 22 . An extension rod 70 is provided at one end with a handle 71 and at the other end with an external thread 72 to be releasably brought into engagement with the internal thread 27 of the handle 20 and to releasably connect the extension rod 70 to the handle 20 , whereby the saw is extended without additional parts. The saw with the saw blade 30 can then be used for cutting or sawing branches in the upper regions of a tree.
Ein Befestigungselement 73 erstreckt sich durch eine Gewindebohrung 29 am anderen Ende des Handgriffs 20 und greift an der Verlängerungsstange 70 an, um die Verlängerungsstange 70 zusätzlich am Handgriff 20 zu sichern.A fastening element 73 extends through a threaded bore 29 at the other end of the handle 20 and engages on the extension rod 70 in order to additionally secure the extension rod 70 on the handle 20 .
