/ Motorbetriebene Stichsäge für Handbetrieb ^p> / Motorized jigsaw for manual operation ^ p>
Die Neuerung betrifft eine motorbetriebenen Stichsäge für Handbetrieb gemäß Oberbegriff des Schutzanspruchs 1.The innovation relates to a motor-driven jigsaw for manual operation according to the preamble of claim 1.
Beim Betrieb einer derartigen Stichsäge läßt es sich nicht vermeiden, daß Sägespäne, insbesondere beim Sägen von spröden Materialien, Augen und Gesicht erheblich gefährden. Bei stationärer Maschinen hat man aus diesem Grunde feste Schutzvorrichtungen vorgesehen und außerdem das Tragen einer Schutzbrille zur Auflage gemacht.When operating such a jigsaw, it cannot be avoided that sawdust, especially when sawing brittle materials, seriously endangers eyes and face. With inpatient For this reason, machines have been provided with fixed protective devices and, in addition, protective goggles have to be worn to rest on them made.
Bei handbetriebenen Stichsägen jedoch kann, je nachdem in welchem Winkel gearbeitet werden muß, das Tragen einer solchen Schutzbrille die Beweglichkeit und den Gesichtskreis einengen. Außerdem muß der mit der motorbetriebenen Stichsäge Arbeitende, um einen möglichst genauen Sägeschnitt zu erreichen, mit dem Kopf nahe am Ort des Geschehens sein. Bei einem derartigen Kdndbetrieb waren dann lediglich die Augen durch Tragen einer Brille geschützt, das übrige Gesicht jedoch den hochspritzenden heißen Spänen ausgesetzt, so daß Hautreizungen bzw. Verletzungen die Folge waren.With hand-operated jigsaws, however, depending on the angle at which you have to work, you may want to wear one Safety glasses restrict mobility and the field of vision. In addition, the person working with the motorized jigsaw must In order to achieve the most precise saw cut possible, be with your head close to the scene. With such a customer service Then only the eyes were protected by wearing glasses, the rest of the face, however, the hot ones Exposed to chips, so that skin irritation or injuries were the result.
Der Neuerung liegt die Aufgabe zugrunde, gattungsgemäße Stichsägen so zu gestalten, daß der Betreiber durch unkontrolliert herumfliegende Sägespäne nicht beeinträchtigt wird, und zwar auch dann, wenn er keine Brille trägt.The innovation is based on the task of generic jigsaws designed in such a way that the operator is not affected by sawdust flying around in an uncontrolled manner, namely even when he's not wearing glasses.
Die neuerungsgemäße Aufgabe wird dadurch gelöst, daß vor der aus Sägeblatt und Hubkolben bestehenden Arbeitseinheit der Stichsäge nach oben hin eine Abschirmung am Gehäuse befestigt ist, daß die Abschirmung transparent ist und sowohl aus Kunststoff als auch aus Sicherheitsglas bestehen kann. Ein weiteres neuerungsgemäßes Kennzeichen ist darin zu sehen, daß die Abschirmung glockenförmig oder als ebene Scheibe ausgebildet ist und mittels Schrauben oder durch Steckverbindung an der Stichsäge befestigt ist. Erfindungsgemäß ist die Abschirmung im wesentlichen parallel zur Schnittebene angeordnet.The object according to the invention is achieved in that the jigsaw is in front of the working unit consisting of the saw blade and the reciprocating piston at the top a shield is attached to the housing, that the shield is transparent and made of plastic as well can consist of safety glass. Another characteristic according to the innovation can be seen in the fact that the shielding is bell-shaped or is designed as a flat disc and is attached to the jigsaw by means of screws or a plug connection. According to the invention, the shield is arranged essentially parallel to the cutting plane.
Die Neuerung wird nun anhand der sie beispielsweise wiedergebenden Zeichnung näher erläutert und beschrieben, wobeiThe innovation is now based on the example it reproduces Drawing explained and described in more detail, wherein
Fig. 1 eine Ansicht einer Stichsäge mit der neuerungsgemäßen Abschirmung undFig. 1 is a view of a jigsaw with the shield according to the innovation and
Fig. 2 eine neuerungsgemäiZe Abschirmung mit Blickwinkel schräg von oben2 shows a shield according to the innovation Angle of view at an angle from above
wiedergibt.reproduces.
Fig. 1 zeigt eine ansich bekannte motorbetriebene Handstichsäge 2 mit dem Getriebe 3, einem Gleitschlitten U, einem Sägeblatt 5 und der neuerungsgemäften Abschirmung 6. Bei dieser zeichnerischen Darstellung ist die Abschirmung 6 oberhalb des Gleitschlittens 4 durch die Bohrungen 7 mittelsFig. 1 shows a known motor-operated jigsaw 2 with the gear 3, a slide U, a saw blade 5 and the shield 6 according to the innovation. In this drawing, the shield is 6 above the slide 4 through the holes 7 by means of
Schrauben zwischen Getriebe 3 und Gleitschlitten 4, oberhalb der wirksamen Länge des Sägeblattes 5 angebracht. Fig. 2 zeigt eine mögliche neuerungsgemäße Ausführungsform der Abschirmung 6 mit Bohrungen 7> wobei der Rand 8 wahlweise schwalbenschwanzförmig ausgebildet sein kann, um eine kraftschlüssige Steckverbindung an der Handstichsäge 2 sicher zu stellen.Screws between gear 3 and slide 4, attached above the effective length of the saw blade 5. Fig. 2 shows a possible embodiment of the innovation according to shield 6 with holes 7> wherein the rim 8 may be optionally dovetailed to provide a force-fit connector on the Portable jigsaw 2 safely.
