Abstract

The rectangular rubber box (A) has flanges 1 mm thick and has a depth of 1 cm. It is open at the front and fits on the sides of the motor. The flexible box has corrugations in its rear surface. A pipe (B) runs from one short side of the box to blow air onto the cutting region of the saw. The box with the flange may measure 4.5x6 cm.

Description

BESCHREIBUNGDESCRIPTION

Der Abluftumlenker für Stichsägen älteren Herstellungsdatums besteht aus
1,2mm starken Gummi, um sich durch seine Biegsamkeit an die verschiedenen Gehäuseformen von Stichsägen anzupassen.The exhaust air deflector for jigsaws of older manufacture consists of
1.2mm thick rubber to allow flexibility to adapt to the different housing shapes of jigsaws.

Auf der Rückseite des umlaufenden Gummirandes befindet sich ein Klebeband, das nach Abziehen einer Schutzfolie den Abluftumlenker an der Maschine über dem Kühlluftaustritt - mit Schlauch nach unten - fixiert.On the back of the surrounding rubber edge there is an adhesive tape which, after removing a protective film, fixes the exhaust air deflector to the machine above the cooling air outlet - with the hose pointing downwards.

Der Schlauch wird mittels eines Klebepats auf dem Geräteschlitten so
befestigt, dass die umgelenkte Luft direkt neben dem Sägeblatt austritt.The hose is attached to the device carriage using an adhesive pad
so that the redirected air exits directly next to the saw blade.

Der Schlauch ist je nach Maschinentyp individuell zu kürzen. Bei
Inbetriebnahme des Gerätes wird somit die vorgezeichnete, zu sägende Linie
von Spänen freigehalten.The hose must be shortened individually depending on the machine type.
When the device is put into operation, the pre-drawn line to be sawed
kept free of chips.

Claims (1)

Der Abluftumlenker für Stichsägen kennzeichnet sich dadurch, daß er die Zuluft zur Kühlung der Maschine zum Sägeblatt hin umlenkt und so die vorgezeichnete, zu sägende Linie von Sägespänen freihält.
Der Umlenker besteht aus 1,2 mm starkem Gummi, der sich duch eine Faltenprägung in der Mitte des Teils an die jeweilige Geräteform anpasst.
Mittels des umlaufenden Kleberandea wird er über dem Luftaustritt der Maschine mit dem Schlach nach unten befestigt.
Der Schlauch wiederum wird durch ein Klebepat auf dem Schlitten der Maschine so fixiert, daß die umgelenkte Kühlluft, nach individueller Kürzung des Schlauches, direkt neben- bzw. vor dem Sägeblatt austritt. The exhaust air diverter for jigsaws is characterized by the fact that it diverts the supply air for cooling the machine towards the saw blade and thus keeps the pre-marked line to be sawn free of sawdust.
The deflector is made of 1.2 mm thick rubber, which adapts to the respective device shape thanks to a fold in the middle of the part.
Using the adhesive strip all around, it is attached above the machine's air outlet with the hose pointing downwards.
The hose, in turn, is fixed to the machine's carriage using an adhesive pad so that the redirected cooling air, after the hose has been individually shortened, exits directly next to or in front of the saw blade.
