Abstract

A chain guide for a chain saw for making joints in masonry in which a dampproof course is inserted consists of a so-called guide bar which connects the drive and deflecting wheels for the chain. The chain is guided in a groove which runs along approximately the whole length of the guide bar on both longitudinal edges of the guide bar. The lateral ridges which delimit the chain guide groove laterally have recesses through which the debris is extracted.

Description

KETTENFUHRUNG EINER KETTENSAGE CHAIN GUIDE OF A CHAIN SAGE
Die Erfindung betrifft die Kettenführung bei einer Kettensäge für die Herstellung von Fugen in Mauerwerk, in welche eine Feuchtigkeitsisolierung eingebracht wird, wobei die Kettenführung durch ein sogenanntes Schwert, welches Antriebs- und Umlenkrad für die Kette verbindet, gebildet ist, bei dem die Kette in einer Nut geführt ist, die in etwa über die ganze Schwertlänge an beiden Längsrädern desselben verläuft.The invention relates to the chain guide in a chainsaw for the production of joints in masonry, into which moisture insulation is introduced, the chain guide being formed by a so-called sword, which connects the drive and deflection wheel for the chain, in which the chain in one Groove is guided, which extends approximately over the entire length of the sword on both longitudinal wheels of the same.
Kettensägen haben den Vorteil, daß sie bei der Herstellung von Mauerfugβn auch bei beengten Raumverhältnissen verwendet werden können, da sie transportabel und ohne weiteres von einer Person gehandhabt werden können. Zudem sind sie auf Grund ihrer Bauweise für Schnitte geringer Fugenbreite geeignet, welche ohne technischen Aufwand in jeder beliebigen, dh. vorzugsweise horizontalen oder vertikalen Richtung hergestellt werden können. Bei herkömmlichen Kettensägen zum Bearbeiten von Stein, Mauerwerk und dgl. setzt sich Abraummaterial wie Staub und körniges Mauerwerkgut in der Führungsbahn für die Kette ab. Dies führt zu erhöhten Verschleiß der Kette und auch des Schwertes, zumal die übliche Schmierung bzw. Kühlung der Kette beeinträchtigt ist. Hiedurch komnmt es zu verringerten Standzeiten für Kette und Schwert. Zur Vermeidung dieser Nachteile weisen erfindungsgemäß die Seitenstege, welche die Nut für die Kettenführung seitlich begrenzen, Ausnehmungen auf, durch die Abraummaterial ausgetragen wird.Chainsaws have the advantage that they can be used in the production of wall joints even in confined spaces, since they can be transported and easily handled by one person. In addition, due to their design, they are suitable for cuts with a small joint width, which can be made in any, ie, without any technical effort. preferably horizontal or vertical direction can be produced. With conventional chainsaws for working stone, masonry and the like. Clearing material such as dust and granular masonry material settles in the guideway for the chain. This leads to increased wear of the chain and also of the sword, especially since the usual lubrication or cooling of the chain is impaired. This leads to reduced downtime for the chain and sword. To avoid these disadvantages, the side webs according to the invention have the groove for the chain guide limit laterally, recesses through which the waste material is discharged.
Durch die erfindungsgemäßen Ausnehmungen in den Seitenstegen, welche die Führungsnut für die Kette seitlich begrenzen, kann das bei der Herstellung von Mauerfugen entstehende Abraummaterial abfließen. Die Größe der Ausnehmungen ist hiebe! so gewählt, daß eine relevante Verminderung der Festigkeitseigenschaften des Schwertes bzw. seines Randbereiches nicht eintritt.Due to the recesses according to the invention in the side webs, which laterally limit the guide groove for the chain, the clearing material which arises during the production of wall joints can flow away. The size of the recesses is huge! chosen so that there is no relevant reduction in the strength properties of the sword or its edge region.
Selbstverständlich können die Ausnehmungen in den Seitenstegen in beliebiger Form ausgeführt sein. Vorzugsweise bestehen die Ausnehmungen jedoch aus Rundlöchern, d. h. Bohrungen bzw. Langlöchern, welche beispielsweise einfach durch einen Fingerfräser hergestellt werden und insbesonders nachträglich bei handelsüblichen Kettensägen im Randbereich des Schwertes angebracht werden können. Es können die Ausnehmungen aber auch rechteckig, quadratisch, trapezförmig oder dreieckig sein, wobei diese Formen vorteilhaft bereits bei der Herstellung des Schwertes gestanzt werden. Gegenstand der Erfindung ist es auch, die Ausnehmungen bis an den Rand der Seitenstege zu führen, sodaß sie keine geschlossene Bβrandung aufweisen, sondern zum Längsrand des Schwertes hin offen sind. Solche Ausnehmungen können ebenfalls leicht nachträglich bei handelsüblichen Kettensägen angebracht werden. Schließlich können die Ausnehmungen in gleichmäßigen Abständen angeordnet werden oder in Umlaufriehtung der Kette ansteigend dichter gesetzt werden. Hiedurch wird das in Kettenumlaufriehtung ansteigend anfallende Abraummaterial besser aus der Führungsnut ausgetragen. Die Ausnehmungen sollen bei allen Ausnehmungsformen bis zur Basisfläche der Nut, d.h. jener Fläche, die die Nut neben den Seitenstegen begrenzt, reichen. Hiedurch wird vermieden, daß sich Abraummaterial in den durch die Seitenstege und der Basisfläche gebildeten Ecken ansammeln kann. Of course, the recesses in the side webs can be made in any shape. However, the recesses preferably consist of round holes, ie bores or elongated holes, which are produced, for example, simply by means of a finger cutter and, in particular, can be retrofitted to commercially available chainsaws in the edge region of the sword. However, the recesses can also be rectangular, square, trapezoidal or triangular, these shapes advantageously being punched out during the manufacture of the sword. The object of the invention is also to guide the recesses to the edge of the side webs so that they do not have a closed border, but are open towards the longitudinal edge of the sword. Such recesses can also be easily retrofitted to commercially available chainsaws. Finally, the recesses can be even Intervals are arranged or are set closer together in increasing direction of the chain. In this way, the debris material that increases in the direction of the chain circulation is better discharged from the guide groove. With all recess shapes, the recesses should extend to the base surface of the groove, that is to say the surface which delimits the groove next to the side webs. This avoids that debris can accumulate in the corners formed by the side webs and the base surface.
