Description
Handkreissäge mit einer Tragschiene für eine Circular saw with a mounting rail for one
Parallelanschlag Die Erfindung bezieht sich auf eine Handkreissäge mit einer in deren Grundplatte verschiebbar geführten und in der jeweils gewünschten Lage arretierbaren Tragschiene für einen Parallelanschlag. Bei mit einem Parallelanschlag dieser Art ausgerüsteten Handkreissägen ist die Tragschiene gewöhnlich als Stahlschiene von rechteckförmigem Querschnitt ausgebildet, die in wenigstens einer dafür vorgesehenen Ausnehmung in der Grundplatte der Handkreissäge geführt ist. Rip fence The invention relates to a circular saw with a slidably guided in the base plate and in the desired one Lockable support rail position for a rip fence. With a rip fence Hand-held circular saws equipped with this type of mounting rail are usually made of steel formed by a rectangular cross-section, which is provided in at least one Recess is guided in the base plate of the circular saw.
Wie die Praxis gezeigt hat, läßt eine solche Ausbildung und Führung der Tragschiene für den Parallelanschlag hinsichtlich der Genauigkeit des Parallelanschlags zu wünschen übrig.As practice has shown, such training and leadership leave us alone the support rail for the rip fence with regard to the accuracy of the rip fence to be desired.
Der Erfindung liegt die Aufgabe zugrunde, unter Uberwindung der Nachteile des Standes der Technik mit einen Geringstmaß an Aufwand die Genauigkeit des Parallelanschlags zu verbessern.The invention is based on the object of overcoming the disadvantages the prior art with a minimum of effort the accuracy of the rip fence to improve.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Tragschiene trapezformigen Querschnitt aufweist und in einer entsprechend ausgebildeten Aufnahme in und/oder an der Grundplatte geführt ist.This object is achieved according to the invention in that the support rail has trapezoidal cross-section and in a correspondingly designed receptacle is guided in and / or on the base plate.
Der Gegenstand der Erfindung wird im nachstehenden anhand der Zeichnung, die ein bevorzugtes Ausführungsbeispiel schematisch veranschaulicht, erläutert.The subject matter of the invention is explained below with reference to the drawing, which illustrates a preferred embodiment schematically explained.
Es zeigen: Fig.1 eine Draufsicht auf eine Handkreissäge mit Parallelanschlag, Fig.2 eine Ansicht längs des Schnittes A-B durch Fig.1) Fig.3 eine Teilansicht in Richtung C.They show: FIG. 1 a plan view of a circular saw with a rip fence, FIG. 2 shows a view along the section A-B through FIG. 1) FIG. 3 shows a partial view in Direction C.
Bei der Handkreissäge gemäß Fig.1 ist mit 1 der Antriebsmotor, mit 2 dessen Handgriff, mit 3 die Schutzhaube, mit 4 die Grundplatte und mit 5 der Parallelanschlag bezeichnet, der an einer Tragschiene 6 beispielsweise durch Schweißung befestigt ist.In the hand-held circular saw according to FIG. 1, 1 is the drive motor, with 2 its handle, 3 the protective hood, 4 the base plate and 5 the rip fence referred to, which is attached to a support rail 6, for example by welding is.
Die Tragschiene 6 weist, wie die Fig.2 und 3 zeigen, rapezquerschnitt auf und ist in einer entsprechend ausgebildeten Aufnahme 7 in der Grundplatte 4 geführt. Dabei liegt die längere Grundlinie 8 des Querschnittstrapezes 9 bezogen auf die Ebene der Grundplatte oben. Es ist selbstverständlich auch möglich, die Tragschiene umgekehrt zu führen, also so, daß die kürzere Grundlinie 10 oben liegt.The support rail 6, as shown in FIGS. 2 and 3, has a cross section and is in a correspondingly designed receptacle 7 in the base plate 4 guided. The longer base line 8 of the cross-sectional trapezoid 9 is related on the level of the base plate above. It is of course also possible that To run the carrier rail reversed, so that the shorter base line 10 is on top.
Die Arretierung der zweckmäßigerweise mit einer Maßeinteilung 11 versehenen Tragschiene 6 erfolgt mittels einer Flügelschraube 12, deren Gewindeschaft 13 mit einer unverdrehbar in einer Gleitmuffe 14 befindlichen Mutter 15 korrespondiert und über eine Druckscheibe 16 auf die Tragschiene 6 einwirkt (Fig.2).The locking of the expediently provided with a scale 11 Support rail 6 takes place by means of a wing screw 12, the threaded shaft 13 with a nut 15 located in a sliding sleeve 14 so that it cannot rotate and acts on the support rail 6 via a pressure disk 16 (FIG. 2).
Die Gleitmuffe 14, die zwecks Aufnahme der Tragschiene 6 mit einer trapezförmigen Ausnehmung 7 versehen ist, ist Bestandteil der Grundplatte 4 oder kann hiervon Bestandteil sein. Der Maßeinteilung 11 der Tragschiene 6 ist eine Bezugsmarke 17 zugeordnet (Fig.1).The sliding sleeve 14, for the purpose of receiving the support rail 6 with a trapezoidal recess 7 is provided, is part of the base plate 4 or can be part of this. The graduation 11 of the mounting rail 6 is a reference mark 17 assigned (Fig. 1).
Durch die spielfreie Führung der Tragschiene in der Bodenplatte der Handkreissäge und/oder in der Gleitmuffe 14 ist auch eine exakte E'uhrung des Parallelanschlags 5 gewährleistet.The backlash-free guidance of the mounting rail in the base plate of the Hand-held circular saw and / or in the sliding sleeve 14 is also an exact guide for the rip fence 5 guaranteed.
