Description

Die vorliegende Erfindung betrifft ein Holzspaltgerät mit einem Spaltkeil, einer am Keilrücken des Spaltkeiles mit diesem verbundenen Führungsstange und einem die Führungsstange und einem die Führungsstange im Querschnitt umschließenden und längs der Führungsstange verschiebbaren Fallgewicht, wobei die Führungsstange an ihrem dem Spaltkeil zugewandten Endbereich mit einem Außengewinde versehen ist und in eine an dem Keilrücken eingebrachte Gewindebohrung eingeschraubt ist.The present invention relates to a wood splitter with a splitting wedge, one on the wedge back of the splitting wedge associated with this guide rod and the guide rod and the guide rod in cross-section enclosing and displaceable along the guide rod case weight, wherein the guide rod provided at its the splitting wedge end facing with an external thread is and is screwed into a threaded bore introduced at the wedge back.

Holzspaltgeräte der vorerwähnten Art sind an sich bekannt und haben sich hinsichtlich ihrer Spaltwirkung sowie ihrer einfachen Bedienung in der Praxis grundsätzlich bewährt.Wood splitting devices of the aforementioned type are known per se and have basically proven themselves in practice in terms of their splitting effect and their ease of use.

Ein Problem der bekannten Holzspaltgeräte besteht hinsichtlich der Dauerhaftigkeit der Verbindung zwischen dem Spaltkeil einerseits und der Führungsstange andererseits.A problem of the known wood splitter is in terms of durability of the connection between the splitting wedge on the one hand and the guide rod on the other.

Durch das Fallgewicht werden beim Auftreffen auf den Spaltkeil enorm hohe Kräfte wirksam, welche bislang verhältnismäßig schnell zu einer Zerstörung der Verbindung zwischen Spaltkeil und Führungsstange geführt haben, unabhängig davon, in welcher konstruktiven Form der Spaltkeil und die Führungsstange miteinander verbunden worden sind. Bei der Abwärtsbewegung des Fallgewichtes können auf den Spaltkeil mehrere Tonnen Schlaggewicht wirken.As a result of the drop weight, enormously high forces become effective when hitting the splitting wedge, which hitherto has been relatively quick to destroy the connection have led between riving knife and guide rod, regardless of which structural form of the riving knife and the guide rod have been connected together. During the downward movement of the falling weight, several tons of impact weight can act on the riving knife.

Eine gegenüber der Fallbewegung des Fallgewichts anders geartete Belastung des Verbindungsbereiches zwischen Spaltkeil und Führungsstange entsteht dann, wenn der Spaltkeil aus einem Holzstück herausgezogen werden muß. Dies erfolgt dadurch, daß das Fallgewicht vom Benutzer längs der Führungsstange schnell nach oben und gegen einen Endanschlag an der Führungsstange angeschlagen wird, um Zugkräfte auf den Spaltkeil ausüben zu können. Auch diese Zugkräfte können den Verbindungsbereich zwischen dem Spaltkeil und der Führungsstange beeinträchtigen.A relation to the falling movement of the drop weight of a different nature of the connection area between splitting wedge and guide rod is formed when the splitting wedge has to be pulled out of a piece of wood. This is done by the case weight is struck by the user along the guide rod quickly upwards and against an end stop on the guide rod in order to exert tensile forces on the riving knife can. These tensile forces can affect the connection area between the riving knife and the guide rod.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Holzspaltgerät der gattungsgemäßen Art zu schaffen, bei dem die Gefahr der Beschädigung oder Zerstörung der Verbindung zwischen Spaltkeil und Führungsstange bei ordnungsgemäßem Gebrauch des Holzspaltgerätes deutlich vermindert ist.The present invention has for its object to provide a wood splitter of the generic type, in which the risk of damage or destruction of the connection between riving knife and guide rod is reduced significantly with proper use of the wood splitter.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, das zwischen dem Fallgewicht und dem Spaltkeil eine Zwischenhülse aus Kunststoff angeordnet ist und eine Längsachse der Führungsstange lotrecht zu den einander gegenüber liegenden Stirnflächen der Zwischenhülse und dem Keilrücken verläuft. Durch die lotrechte Ausrichtung der Zwischenhülse und der Stirnfläche des Keilrückens werden beim Auftreffen des Fallgewichtes seitliche Knickkräfte vermieden, die bisher erhebliche Probleme in dem Verbindungsbereich zwischen Führungsstange und Spaltkeil gesorgt haben. Durch diese konstruktiven Maßnahmen wird daher eine hohe Betriebssicherheit der Verbindung zwischen Spaltkeil und Führungsstange erreicht, insbesondere wenn die Zwischenhülse die Führungsstange ringförmig umgreift und somit auch für eine gleichmäßige Kraftverteilung sorgt.This object is achieved in that is arranged between the case weight and the splitting wedge an intermediate sleeve made of plastic and a longitudinal axis of the guide rod is perpendicular to the opposite end faces of the intermediate sleeve and the wedge back. Due to the vertical alignment of the intermediate sleeve and the end face of the wedge back lateral bending forces are avoided when hitting the falling weight, which have previously caused considerable problems in the connection area between the guide rod and riving knife. By this design measures, therefore, a high reliability of the connection between riving knife and guide rod is achieved, especially when the intermediate sleeve annularly engages around the guide rod and thus ensures a uniform force distribution.

Diese Ausgestaltung der Zwischenhülse ist insbesondere herstellungstechnisch besonders einfach und damit preiswert, da hier lediglich darauf zu achten ist, dass die ebenen Flächen rechtwinklig zur Längsachse der Führungsstange verlaufen. Alternativ bestünde auch die Möglichkeit, die einander gegenüber liegenden Stirnflächen des Keilrückens und der Zwischenhülse stumpfkegelig oder ballig auszubilden, aber dann kann es in der Praxis zu Querbelastungen zwischen Führungsstange und Spaltkeil beim Auftreffen des Fallgewichtes kommen, die die Verbindung beschädigen.This embodiment of the intermediate sleeve is in particular manufacturing technology particularly simple and therefore inexpensive, since it is only necessary to ensure that the flat surfaces are perpendicular to the longitudinal axis of the guide rod. alternative There would also be the possibility of frustoconical or spherical form the opposing faces of the wedge back and the intermediate sleeve, but then it can come in practice to cross loads between the guide rod and riving knife when hitting the case weight that damage the connection.

Eine besonders einfache Ausführung besteht darin, dass die einander gegenüber liegenden Stirnflächen des Keilrückens einerseits und der Zwischenhülse andererseits als ebene Flächen ausgebildet sind. Die Zwischenhülse besitzt über die Längsachse gesehen einen gleichbleibenden Querschnitt und sorgt somit auch für eine gleichmäßige Kraftverteilung. Die Zwischenhülse erstreckt sich dabei konzentrisch zu der Führungsstange, so dass beim Auftreffen des Fallgewichtes ausschließlich in Eintreibrichtung des Spaltkeiles gerichtete Kräfte auftreten, d. h., der Spaltkeil wird nicht in Querrichtung zur Längsachse der Führungsstange beaufschlagt, wie es z. B. der Fall ist, wenn eine oder beide einander zugewandten Stirnflächen zwischen Keilrücken und Zwischenhülse gegenüber der Längsachse der Führungsstange geneigt verlaufen.A particularly simple embodiment is that the opposite end faces of the wedge back on the one hand and the intermediate sleeve on the other hand are formed as flat surfaces. The intermediate sleeve has seen over the longitudinal axis a constant cross-section and thus also ensures a uniform force distribution. The intermediate sleeve extends concentrically to the guide rod, so that when hitting the falling weight forces directed exclusively in the driving direction of the splitting wedge, d. h., The splitting wedge is not acted upon in the transverse direction to the longitudinal axis of the guide rod, as z. B. is the case when one or both facing end surfaces between wedge back and intermediate sleeve with respect to the longitudinal axis of the guide rod inclined.

Ferner ist es vorteilhaft, wenn durch einen Kleber die Schraubverbindung gesichert wird und dadurch auch eine hohe Belastbarkeit der Verbindung gegenüber Zugkräften erreicht wird, die beim Versuch entstehen, den Spaltkeil durch schnelles Hochschieben des Fallgewichtes gegen einen Endanschlag am oberen Ende der Führungsstange aus einem Holzstück zu lösen. Für eine beanspruchbare Verbindung ist das Gewinde an der Führungsstange als Feingewinde ausgeführt und über einen längeren Bereich in den Spaltkeil eingeschraubt.Further, it is advantageous if the screw is secured by an adhesive and thereby a high load capacity of the connection is achieved against tensile forces that arise when attempting the riving knife by rapidly pushing the drop weight against a stop at the top of the guide rod from a piece of wood to solve. For a claimable connection, the thread on the guide rod is designed as a fine thread and screwed over a longer range in the riving knife.

Weitere Merkmale der Erfindung sind Gegenstand weiterer Unteransprüche.Further features of the invention are the subject of further subclaims.

Ein Ausführungsbeispiel der Erfindung ist in den beigefügten Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigen:

Figur 2
eine teilweise geschnittene Ansicht der Verbindung zwischen Spaltkeil und Führungsstange des Holzspaltgerätes der Figur 1.
An embodiment of the invention is illustrated in the accompanying drawings and will be described in more detail below. Show it:
FIG. 1
a perspective view of a wood splitter according to the invention,
FIG. 2
a partially sectioned view of the connection between splitting wedge and guide rod of the wood splitter of Figure 1.

In Figur 1 ist mit dem Bezugszeichen 1 insgesamt ein Holzspaltgerät bezeichnet, welches im wesentlichen aus einem Spaltkeil 2, einer Führungsstange 3 und einem Fallgewicht 4 beseht, die vorzugsweise sämtlich aus Metall hergestellt sind. Der Spaltkeil 2 weist an der der Führungsstange 3 gegenüberliegenden Seite eine Schneide auf, von der sich der Spaltkeil 2 zu einem Keilrücken 2a hin verdickt und zudem für eine gute Spaltwirkung schraubenförmig verdreht.In Figure 1, the reference numeral 1 denotes a total of a wood splitter, which essentially consists of a riving knife 2, a guide rod 3 and a case weight 4, which are preferably all made of metal. The riving knife 2 has, on the side opposite the guide rod 3, a cutting edge from which the riving knife 2 thickens to form a wedge back 2a and, moreover, helically turns it for a good splitting effect.

Die Führungsstange 3 ist am Keilrücken 2a des Spaltkeiles 2 mit diesem verbunden.The guide rod 3 is connected to the wedge back 2a of the riving knife 2 with this.

Das im wesentlichen zylindrisch ausgebildete Fallgewicht 4 umschließt die Führungsstange 3 konzentrisch und ist längs der Führungsstange 3 frei verschiebbar.The substantially cylindrical case weight 4 encloses the guide rod 3 concentrically and is freely displaceable along the guide rod 3.

Zwischen dem Fallgewicht 4 und dem Spaltkeil 2 ist eine Zwischenhülse 5 aus Kunststoff mit einer zylindrischen Bohrung 5a angeordnet. Die Zwischenhülse 5 ist konzentrisch formschlüssig oder mit geringem Spiel um die Führungsstange 3 angeordnet und weist einen gleichbleibenden Querschnitt auf. Die einander zugewandten Flächen zwischen der Fallgewicht 4 und der Zwischenhülse 5 sind eben ausgebildet und erstrecken sich lotrecht zu der Längsachse L der Führungsstange 3.Between the falling weight 4 and the splitting wedge 2, an intermediate sleeve 5 made of plastic with a cylindrical bore 5a is arranged. The intermediate sleeve 5 is concentrically arranged with a form fit or with little play around the guide rod 3 and has a constant cross-section. The facing surfaces between the falling weight 4 and the intermediate sleeve 5 are flat and extend perpendicular to the longitudinal axis L of the guide rod. 3

Die Führungsstange 3 ist an ihrem dem Spaltkeil 2 zugewandten Ende mit einem als Feingewinde ausgebildetem Außengewinde 3a versehen und mit diesem in eine vom Keilrücken 2a ausgehende Gewindebohrung 2b eingeschraubt. Die Länge des eingeschraubten Bereiches ist so bemessen, dass die Gewindeverbindung auch dauerhaften Belastungen standhält. Vorzugsweise liegt die Einschraubtiefe über 3cm, etwa zwischen 4 und 6cm. Die Schraubverbindung zwischen der Führungsstange 3 und dem Spaltkeil 2 ist zusätzlich durch einen Kleber gesichert.The guide rod 3 is provided at its the splitting wedge 2 facing the end with a fine thread formed as external thread 3a and screwed with this in an outgoing from the wedge back 2a threaded bore 2b. The length of the screwed-in area is dimensioned so that the threaded connection withstands permanent loads. The depth of engagement is preferably about 3 cm, for example between 4 and 6 cm. The screw connection between the guide rod 3 and the splitting wedge 2 is additionally secured by an adhesive.

Die einander zugewandten Stirnflächen 2a und 5b des Spaltkeiles 2 einerseits und der Zwischenhülse 5 andererseits sind im dargestellten Ausführungsbeispiel als ebene Flächen ausgebildet, wobei die Längsachse L der Führungsstange 3 lotrecht zu diesem Stirnflächen 5b und 2a verläuft.The mutually facing end surfaces 2a and 5b of the splitting wedge 2 on the one hand and the intermediate sleeve 5 on the other hand are in the illustrated embodiment as a plane Formed surfaces, wherein the longitudinal axis L of the guide rod 3 is perpendicular to this end faces 5b and 2a.

Wird das Fallgewicht 4 aus einer Position im oberen Endbereich der Führungstange 3 fallengelassen, so schlägt dieses Fallgewicht auf die auf dem Keilrücken 2a des Spaltkeiles 2 aufliegende Zwischenhülse 5 auf. Die dabei frei werdenden Kräfte wirken ausschließlich in Richtung der Längsachse L der Führungsstange 3, d. h., es werden keine Kräfte wirksam, die den Spaltkeil 2 quer zur Richtung der Längsachse L der Führungsstange 3 belasten. Somit wird auch der Verbindungsbereich zwischen Spaltkeil 2 und Führungsstange 3 nicht durch Querkräfte belastet, woraus eine extrem lange Lebensdauer der Verbindung zwischen Spaltkeil 2 und Führungsstange 3 resultiert.If the drop weight 4 is dropped from a position in the upper end region of the guide rod 3, this drop weight strikes the intermediate sleeve 5 resting on the wedge back 2a of the splitting wedge 2. The forces released thereby act exclusively in the direction of the longitudinal axis L of the guide rod 3, d. h., There are no forces acting on the splitting wedge 2 transverse to the direction of the longitudinal axis L of the guide rod 3. Thus, the connection region between riving knife 2 and guide rod 3 is not loaded by transverse forces, resulting in an extremely long life of the connection between riving knife 2 and guide rod 3 results.

Soll der Spaltkeil 2 aus einem zu spaltenden Holzklotz herausgezogen werden, wird das Fallgewicht 4 von Hand längs der Führungsstange 3 rasch nach oben gezogen und dort gegen einen Endanschlag 8 angeschlagen, wobei die Anschlagflächen am Endanschlag 8 und dem Fallgewicht 4 wieder lotrecht zur Längsachse L der Führungsstange 3 ausgebildet sind. Die hierbei auftretenden, auch wieder ausschließlich in Längsrichtung der Führungsstange 3 wirksam werdenden Zugkräfte auf dem Bereich der Schraubverbindung werden durch die beschriebenen Sicherungsmaßnahmen der Schraubverbindung dauerhaft aufgenommen. Bei den Sicherungsmaßnahmen handelt es sich, wie schon gesagt, um die Verklebung im Gewindebereich.If the riving knife 2 are pulled out of a log to be split block, the case weight 4 by hand along the guide rod 3 is pulled up quickly and struck against an end stop 8, the stop surfaces on the end stop 8 and the fall weight 4 again perpendicular to the longitudinal axis L of Guide rod 3 are formed. The occurring here, again exclusively in the longitudinal direction of the guide rod 3 become effective tensile forces on the region of the screw are permanently absorbed by the described safety measures of the screw. The safety measures are, as already mentioned, the bonding in the threaded area.

Die Zwischenhülse 5 ist bevorzugt aus einem extrem schlagfesten Kunststoff hergestellt. Durch die Zwischenhülse 5 wird das Aufeinandertreffen von Metall auf Metall beim Herabfallen des Schlaggewichtes 4 verhindert und damit auch die beim Aufeinanderprallen von Metall auf Metall einhergehende Geräuschentwicklung vermieden.The intermediate sleeve 5 is preferably made of an extremely impact-resistant plastic. By the intermediate sleeve 5, the collision of metal on metal when falling of the impact weight 4 is prevented, and thus the noise associated with the collision of metal on metal avoided.
