Eine Sägehilfsvorrichtung ist bereits aus der
Durch die bekannte Sägehilfsvorrichtung wird dabei erreicht, dass beispielsweise bei Abrichtarbeiten im Zimmer- und Schreinergewerbe eine sehr gute Maßhaltigkeit und Winkelgenauigkeit bei entsprechenden Schnitten mit der Kettensäge beispielsweise von Sparren, Kanthölzern und Brettern erreicht wird. Dabei ermöglicht die bekannte Sägehilfsvorrichtung eine örtliche Unabhängigkeit bei der Bearbeitung des zu schneidenden Gegenstands, da diese gerade bei einer benzingetriebenen Kettensäge mit Verbrennungsmotor überall eingesetzt werden kann.By the known Sägehilfsvorrichtung is thereby achieved that, for example, in dressing work in carpentry and carpentry a very good dimensional accuracy and angular accuracy is achieved with appropriate cuts with the chainsaw example of rafters, squared timbers and boards. The known Sägehilfsvorrichtung allows a local independence in the processing of the object to be cut, since this can be used anywhere in a gasoline-powered chainsaw with internal combustion engine.
Allerdings gibt es weitere Einsatzgebiete, beispielsweise beim Beschnitt von Dämmmaterialien, bei welchen neben dem universellen Einsatz der an dem Grundelement gehalterten Kettensäge eine verbesserte Handhabung und Führung wünschenswert ist.However, there are other applications, for example, when trimming insulation materials, in which in addition to the universal use of the content of the base chain saw improved handling and leadership is desirable.
Eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist aus
Aufgabe der vorliegenden Erfindung ist es daher, eine Sägehilfsvorrichtung der eingangs genannten Art zu schaffen, welche eine verbesserte Handhabung und Führung der an dem Grundelement gehalterten Kettensäge ermöglicht.Object of the present invention is therefore to provide a Sägehilfsvorrichtung of the aforementioned type which allows improved handling and management of the content of the base element Chainsaw.
Diese Aufgabe wird erfindungsgemäß durch eine Sägehilfsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a Sägehilfsvorrichtung with the features of claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.
Um eine Sägehilfsvorrichtung der eingangs genannten Art zu schaffen, welche eine verbesserte Handhabung und Führung der an dem Grundelement gehalterten Kettensäge ermöglicht, ist ein Grundgestell mit einer durch dieses höhenverlagerbar getragenen Führungseinrichtung vorgesehen, an welcher das Grundelement einhängbar und entlang welcher das eingehängte Grundelement führbar ist. Über das Grundgestell wird somit die an dem Grundelement gehalterte Kettensäge abgestützt beziehungsweise das Gewicht des Grundelements und der Kettensäge aufgenommen, so dass sich die Kettensäge beim Beschnitt eines entsprechenden Gegenstandes besonders leicht handhaben und führen lässt, indem beispielsweise lediglich die Kraft zum Bewegen der Kettensäge durch die Bedienperson aufgebracht werden muss. Zudem ermöglicht die Führung entlang des Grundgestells einen sehr genau einstellbaren und exakten Schnitt der Kettensäge mit hoher Maßhaltigkeit und Winkelgenauigkeit. Überdies ist ein Grundträger vorgesehen, auf welchem der wenigstens eine zu sägende Gegenstand positionierbar ist und an welchem das Grundgestell abgestützt ist. Der Grundträger ist dabei vorzugsweise auf einer Höhe positioniert, die ein optimales und einfaches Bedienen der Kettensäge ermöglicht.In order to provide a saw auxiliary device of the type mentioned above, which allows improved handling and management of the content of the base element Chainsaw, a base frame is provided with a höhenverlagerbar supported by this guide device to which the base element can be suspended and along which the hinged base element is feasible. About the base frame thus supported on the base element chainsaw is supported or added to the weight of the base member and the chainsaw, so that the chainsaw when trimming a corresponding object particularly easy to handle and run, for example, only the force to move the chainsaw through the Operator must be applied. In addition, the guide along the base frame allows a very precisely adjustable and exact cut of the chainsaw with high dimensional accuracy and angular accuracy. Moreover, a base support is provided, on which the at least one object to be sawed can be positioned and on which the base frame is supported. The base support is preferably positioned at a height that allows optimal and easy operation of the chainsaw.
Erfindungsgemäß ist die Kettensäge an der Halterungsvorrichtung mit der Oberflanke des Schwerts als Vorderflanke der Sägehilfsvorrichtung, mittels der ein Schnitt bewerkstelligbar ist, festlegbar. Da jeweilige Zähne an der Vorderflanke somit ihre Schneide unterseitig tragen, bedeutet dies, dass Sägemehl beziehungsweise Sägespäne vorteilhafterweise in Richtung nach unten transportiert werden.According to the invention, the chain saw can be fixed to the mounting device with the upper flank of the sword as the front flank of the saw auxiliary device, by means of which a cut can be effected. Since respective teeth on the leading edge thus their Wear cutting edge on the underside, this means that sawdust or sawdust are advantageously transported in the downward direction.
Des Weiteren ist der Grundträger beziehungsweise das Grundgestell erfindungsgemäß auf einem Auffangbehältnis der Sägehilfsvorrichtung für Sägemehl, Sägespäne oder dergleichen angeordnet.Furthermore, the base support or the base frame according to the invention is arranged on a collecting container of the Sägehilfsvorrichtung for sawdust, sawdust or the like.
Das Auffangbehältnis ist dabei in seiner Höhe vorzugsweise so dimensioniert, dass der Grundträger beziehungsweise das Grundgestell auf einer Höhe angeordnet sind, die eine einfache Positionierung des jeweiligen, zu sägenden Gegenstands ermöglicht beziehungsweise eine einfache uns komfortable Handhabung der Kettensäge.The collecting container is preferably dimensioned in height so that the base support or the base frame are arranged at a height that allows easy positioning of the respective object to be sawn or a simple us comfortable handling of the chainsaw.
Die beschriebene Sägehilfsvorrichtung eignet sich dabei hervorragend zum Beschnitt von Dämm- und Isoliermaterialien, beispielsweise Dämmplatten oder dergleichen. Gleichwohl eignet sich die Sägehilfsvorrichtung natürlich auch zum Beschnitt von Holz, insbesondere von Sparren, Kanthölzern oder Brettern. Dabei wird das Grundelement nicht entlang der entsprechenden Oberfläche des zu schneidenden Gegenstandes geführt, sondern vielmehr entlang der Führungseinrichtung des Gestells, so dass sich die erfindungsgemäß gewünschte einfache Handhabung besonders gut erreichen lässt. An dem Grundelement, welches bereits in der
Weiterhin vorteilhaft ist es, wenn die Führungseinrichtung entlang jeweiliger Stützen des Grundgestells höhenverlagerbar ist. Hierdurch kann eine optimale Höhenlage der Führungseinrichtung relativ zum zu sägenden Gegenstand eingestellt werden.It is also advantageous if the guide device is vertically displaceable along respective supports of the base frame. In this way, an optimum height position of the guide device can be adjusted relative to the object to be sawn.
In diesem Zusammenhang hat es sich als weiterhin vorteilhaft gezeigt, wenn jeweils wenigstens eine der einander gegenüberliegenden Stützen eine Verzahnung aufweist, welche mit einem jeweils zugeordneten Zahnrad einer Höhenverstelleinrichtung der Führungseinrichtung in Eingriff ist. Somit ergibt sich eine besonders einfache und komfortable Verstellmöglichkeit, und zwar insbesondere dann, wenn in weiterer Ausgestaltung der Erfindung die jeweiligen Zahnräder über eine Welle miteinander verbunden sind, welche beispielsweise manuell mittels einer Kurbel oder aber elektrisch oder dergleichen mittels eines Antriebs betätigbar ist.In this context, it has also proven to be advantageous if in each case at least one of the opposing supports has a toothing, which is in engagement with a respective associated toothed wheel of a height adjustment device of the guide device. This results in a particularly simple and comfortable adjustment, and in particular when, in a further embodiment of the invention, the respective gears are connected to each other via a shaft which, for example manually by means of a crank or electrically or the like by means of a drive can be actuated.
Eine weitere vorteilhafte Ausführungsform der Erfindung sieht vor, dass die Führungseinrichtung mittels eines Fixierungselements relativ zur zugeordneten Stütze lösbar fixierbar ist. Hierdurch kann eine besonders hohe Qualität des Schnitts des jeweiligen Gegenstands erreicht werden.A further advantageous embodiment of the invention provides that the guide device is releasably fixable by means of a fixing element relative to the associated support. In this way, a particularly high quality of the section of the respective object can be achieved.
Eine weitere vorteilhafte Ausführungsform sieht vor, dass an dem Grundelement jeweilige Führungselemente vorgesehen sind, mittels welchen das Grundelement in jeweils korrespondierende Führungselemente der Führungseinrichtung einhängbar und entlang dieser verschiebbar ist. Durch die miteinander zusammenwirkenden Führungselemente auf Seiten des Grundelements und auf Seiten der Führungseinrichtung kann dabei eine äußerst einfache Führung der Kettensäge geschaffen werden.A further advantageous embodiment provides that respective guide elements are provided on the base element, by means of which the base element can be suspended in respective corresponding guide elements of the guide device and slidable along this. By the cooperating guide elements on the side of the base member and on the side of the guide means an extremely simple guidance of the chainsaw can be created.

Da der Sägeschnitt mit der Ober- beziehungsweise Vorderflanke 64 des Schwertes 62 bewerkstelligt wird und demzufolge die Kette 60 gemäß dem Pfeil 68 an der Vorderflanke 64 vom Aufbau beziehungsweise Motor 66 der Kettensäge 52 zur Holzoberfläche hin verläuft, kann - je nach zu schneidendem Material - eine Rückhalteeinrichtung erforderlich sein, welche verhindert, dass das Grundelement 10 beziehungsweise die Kettensäge 52 bei einem Verkeilen der jeweiligen Zähne 64 im Material übermäßig abgehoben beziehungsweise aus der Führungseinrichtung 82 gehoben wird. Dies kann beispielsweise dadurch erfolgen, dass zwischen dem jeweiligen Führungselementen 40 auf Seiten der Sägehilfsvorrichtung und den Führungsschienen 44 ein Hintergriff ausgebildet wird. Dies kann beispielsweise durch eine geeignete Ausbildung des Führungsschlitzes 42, beispielsweise mit einem quer verlaufenden Steg oder dergleichen, erfolgen. Kommt es dann zu einer infolge des Verkantens der bewegten Kette 60 auftretenden Kraft, welche ein Abheben des Grundelements 10 und somit der gesamten Kettensäge 52 bewirken könnte, so sorgt diese Rückhalteeinrichtung, welche vorliegend dann im Bereich der Führungseinrichtung 48 vorgesehen ist, dafür, dass es zu keinem Abheben des Grundelements 10 kommt.Since the saw cut is accomplished with the upper or leading
Als Rückhalteeinrichtung wäre es auch denkbar, am weiteren Führungselement 78, welches vorliegend hinter beziehungsweise parallel zur Rückflanke 70 des Schwertes 62 verläuft, ein entsprechendes Querelement vorzusehen. An dem weiteren Führungselement 78 in Form der Leiste könnte demzufolge beispielsweise eine hierzu in Querrichtung verlaufende weitere Leiste angeordnet sein, welche das Rückhalteelement bildet.As a retaining device, it would also be conceivable to provide a corresponding transverse element on the
