Abstract

The discharge opening for sawdust and chips in the protective hood of a hand-operated circular saw is attachable to a pipe socket. A suction tube is connected to a separate dust duct. The discharge opening (10) is set on the side of the hood (2) next to the drive motor (1). At this point is an attachment pipe socket (8) for a dust bag (9), which is connectable to the air suction circuit of the motor ventilator. The bag may be fitted with a slide fastener.

Description

Handkreissäge mit einer in der Schutz- Circular saw with a protective

haube der Säge angebrachten Spanauswurföffnung Es ist bekannt, Handkreissägen zum Absaugen der beim Sägen ausfallenden Späne auf der dem Antriebsmotor abgewandten Seite der Schutzhaube mit einer Spanauswurföffnung zu versehen, an welche ein AnschluSosutze. mit einem Saugschlauch anschließbar ist, wobei der Saugschlauch mit der Saugseite eines separaten Staubsaugers zu verbinden ist. Hood of the saw attached chip ejection opening It is known, hand-held circular saws for suction of the chips that fall out during sawing on the one facing away from the drive motor To be provided on the side of the protective hood with a chip ejection opening to which a connection socket. can be connected to a suction hose, the suction hose with the suction side a separate vacuum cleaner is to be connected.

Aufgabe der vorliegenden Erfindung ist es, den bisher erforderlichen Aufwand für das Spanabsaugen zu verringern sowie die Handlichkeit der betreffenden Handkreissäge zu verbessern.The object of the present invention is to provide the previously required To reduce the effort for the chip extraction as well as the handiness of the concerned Improve circular saw.

Diese Aufgabe ist dadurch gelöst, daß die Spanauswurföffnung erfindungsgemäß auf der dem Antriebsmotor benachbarten Seite der Schutzhaube vorgesehen ist und dieser Öffnung ein .nschlußstutzen für einen Staubsack zugeordnet ist, der über einen Förderschlauch an den Luftansaugkreis des Motorventilators anschließbar ist. Bei einer derartigen Absaugvorrichtung erübrigt sich die Verwendung eines besonderen Staubsaugers, außerdem wird die Bewegungsfreiheit der Handkreissäge größer und deren Handlichkeit verbessert, weil der relativ lange, vom Anschlußstutzen bis zum Staubsauger reichende Förderschlauch nicht mehr erforderlich ist.This object is achieved in that the chip ejection opening according to the invention is provided on the side of the protective hood adjacent to the drive motor and this opening is assigned a .nschlussstutzen for a dust bag, which is about a delivery hose to the air intake circuit of the motor fan connectable is. With such a suction device, there is no need to use a special one Vacuum cleaner, in addition, the freedom of movement of the circular saw is greater and their Improved handiness, because the relatively long, from the connection piece to the vacuum cleaner A sufficient delivery hose is no longer required.

Ein Ausführungsbeispiel der Erfindung wird im nachstehenden anhand der Zeichnung näher erläutert.An embodiment of the invention is based on the following the drawing explained in more detail.

Es zeigen: Fig. 1 eine Draufsicht auf eine mit der erfindungsgemäßen Staubabsaugung ausgestattete Handkreissäge, Fig. 2 eine Ansicht der Kreissäge nach Fig. 1 in Richtung A.1 shows a plan view of one with the one according to the invention Hand-held circular saw equipped with dust extraction, FIG. 2 shows a view of the circular saw Fig. 1 in direction A.

In den Figuren ist mit 1 der Autriebsmotor, mit 2 die Schutzhaube, mit 3 eine beidseitig geschlossene Pendelschutzhaube, mit 4 ein Sägeblatt und mit 5 der Haupthanagriff bezeichnet, während 7 einen Staubsack kennzeichnet, der räumlich zwischen einem schutzhaubenseitigen Anschlußstutzen 8 und einem Förderschlauch 9 liegt, welcher in die Ansaugzone des Ventilators des Antriebsmotors 1 mündet.In the figures, 1 is the drive motor, 2 is the protective hood, with 3 a pendulum protection hood closed on both sides, with 4 a saw blade and with 5 denotes the main Hanagriff, while 7 denotes a dust bag that spatially between a protective hood-side connection piece 8 and a conveying hose 9 which opens into the suction zone of the fan of the drive motor 1.

Die Sägespäne gelangen im Betriebsfalle der Handkreissäge infolge der Saugwirkung des Motorventilators von der in der Schutzhaube 2 motorseitig angebrachten Spanausçurföffnung 10 über den Anschlußstutzen 8 in den Staubsack 7, der zur raschen Entnahme der Sägespäne und/oder des Sägemehles einen Reißverschluß 6 aufweist. In den Förderschlauch 9 bzw. in den Ausgangsbereich des Staubsackes 7 wird vorteilhafterweise wenigstens ein Filter eingefügt, um ein Eindringen von Säge staub bzw. von Sägespänen in das Motorinnere zu verhindern. Der Antriebsmotor kann im Bedarfsfalle auch mit einem zusätzlichen bzw, separaten Saugventilator ausgerüstet werden.The sawdust arrives in the event of operation of the circular saw as a result the suction effect of the motor fan from the one fitted in the protective hood 2 on the motor side Chip discharge opening 10 via the connecting piece 8 in the dust bag 7, which is used to quickly Removal of the sawdust and / or sawdust has a zipper 6. In the delivery hose 9 or in the exit area of the dust bag 7, at least one filter is advantageously inserted to prevent penetration of To prevent saw dust or sawdust from entering the motor. The drive motor If necessary, it can also be equipped with an additional or separate suction fan will.
