Abstract
Description
Die Erfindung betrifft ein motorgetriebenes Schleifgerät mit einem Schleifkopf und einem Griffstab zum Halten des Schleifgerätes, wobei der Schleifkopf relativ zu einer dem Schleifkopf zugewandten Griff-Endpartie des Griffstabes um mindestens eine Schwenkachse verschwenkbar angeordnet ist und der Schleifkopf eine Absaughaube zum Absaugen des bei der Schleifbearbeitung eines Werkstücks entstehenden Staubes aufweist, die über einen flexiblen Absaugschlauch mit der Griff-Endpartie verbunden ist, wobei der Absaugschlauch mit Abstand zur Schwenkachse vom Schleifkopf absteht und mit gebogenem Verlauf ein Stück weit um die Schwenkachse herum zur Griff-Endpartie verläuft.The The invention relates to a motor-driven grinding device with a Grinding head and a handle for holding the grinder, wherein the grinding head relative to a grinding head facing the handle end of the handle bar is arranged pivotable about at least one pivot axis and the grinding head a suction hood for suction during grinding a workpiece resulting dust, which has a flexible suction hose connected to the handle end section is, wherein the suction hose at a distance from the pivot axis of the grinding head protrudes and with curved course a piece far around the pivot axis around to the handle end section runs.
Derartige Schleifgeräte – auch Langhalsschleifer genannt – können zur schleifenden Bearbeitung von Gebäudewänden und -decken verwendet werden. Dabei wird der ein entsprechendes Schleifmittel tragende Schleifkopf mittels des Griffstabs gegen die zu schleifende Fläche gehalten. Der beim Schleifen entstehende Staub wird zur Reinhaltung der Umgebung durch ge eignete Öffnungen, Kanäle oder dergleichen im ein Schleifmittel tragenden Schleifteller oder dergleichen des Schleifkopfes in die Absaughaube und von dort durch den Absaugschlauch zur Griff-Endpartie gesaugt, von wo der Schleifstaub durch den Griffstab hindurch zu einem an den Griffstab lösbar angeschlossenen äußeren Saugschlauch gelangt, der zu einem Staubsauger führt.such Grinders - also long-necked sander called - can to grinding processing of building walls and ceilings are used. It is the appropriate abrasive carrying grinding head by means of the handle bar against the sanding area held. The dust created during grinding is used to keep the Environment through suitable openings, Channels or the like in an abrasive-carrying pad or the like of the grinding head in the suction hood and from there through the suction hose sucked to the handle end, from where the sanding dust by the handle bar through to an outer suction hose detachably connected to the handle bar which leads to a vacuum cleaner.
Da der Schleifkopf schwenkbar mit der Griff-Endpartie verbunden ist, behält er seine Lage beim Schleifen unabhängig von der momentanen Neigung des Griffstabes bei.There the grinding head is pivotally connected to the handle end section, reserves he's his position when grinding regardless of the current slope of the handle bar at.

Ausgehend hiervon liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Schleifgerät der eingangs genannten Art zu schaffen, bei dem ein unkontrolliertes Hin- und Herschwenken des Schleifkopfes bei Nichtgebrauch des Schleifgerätes vermieden und somit der Schleifkopf in einer möglichst definierten Position relativ zur Griff-Endpartie gehalten wird, so dass ein sicheres Aufsetzen auf das Werkstück ermöglicht wird.outgoing This is the object of the present invention, a sharpener of the type mentioned above, in which an uncontrolled Swiveling the grinding head back and forth when the grinder is not in use and thus the grinding head in a position as defined as possible held relative to the handle end section, so that a secure Placing on the workpiece allows becomes.
Diese Aufgabe wird erfindungsgemäß bei dem eingangs genannten motorgetriebenen Schleifgerät, dadurch gelöst, dass der biegeelastisch ausgebildete Absaugschlauch ein beim Nicht gebrauch des Schleifgerätes den Schleifkopf in einer Ausgangs-Schwenklage mit Bezug auf die Griff-Endpartie haltendes Halteelement bildet, indem am der Absaughaube entgegengesetzten Endbereich des Absaugschlauches ein um eine zur Schwenkachse parallele Gelenkachse schwenkbar mit der Griff-Endpartie verbundenes Schwenkelement angreift, das federbelastet ist, sodass der Absaugschlauch in vom schleifkopfseitigen Ende des Absaugschlauches weg gerichteter Richtung beaufschlagt wird.These Task is according to the invention in the mentioned motor-driven grinder, solved by that the bending elastic trained suction hose when not in use grinder the grinding head in an initial pivotal position with respect to the Handle end part holding holding element forms by the suction hood opposite end of the suction hose to a for Pivot axis parallel articulation axis pivotally connected to the handle end part Swivel element attacks, which is spring-loaded, so that the suction hose in directed from the grinding head end of the suction hose away Direction is applied.
Der Absaugschlauch drückt zum einen gegen den Schleifkopf, sodass der Schleifkopf zur Griff-Endpartie hin schwenken will. Zum anderen übt das Schwenkelement über den Saugschlauch ein entgegengesetztes Schwenkmoment auf den Schleifkopf aus, sodass sich für den Schleifkopf eine definierte Ausgangs-Schwenklage ergibt, in der sich der Schleifkopf kräfte- und momentenmäßig im Gleichgewicht befindet.Of the Suction hose pushes on the one hand against the grinding head, so that the grinding head to the handle end part wants to pan out. On the other hand, that exercises Swivel element over the suction hose an opposite pivoting moment on the grinding head out, so for yourself the grinding head results in a defined output pivotal position, in which the grinding head and moments in balance located.
Die Winkelstellung des Schleifkopfes in der Ausgangs-Schwenklage ist daher von der Größe der auf das Schwenkelement einwirkenden Federkraft und außerdem von der Länge des Absaugschlauchs abhängig. Diese Federkraft wird daher entsprechend groß gewählt werden, um eine für die Handhabung und die Lagerung des Schleifgerätes günstige Ausgangs-Schwenklage des Schleifkopfs zu erhalten.The Angular position of the grinding head in the output pivot position is therefore on the size of the the pivot member acting spring force and also of the length the suction hose dependent. This spring force will therefore be chosen to be large enough for handling and the storage of the grinder favorable To obtain initial swivel position of the grinding head.
Die Ausgangs-Schwenklage wird ferner durch die Biegeelastizität beziehungsweise durch die Steifigkeit des Absaugschlauches beeinflusst. In diesem Zusammenhang ist zweckmäßigerweise vorgesehen, dass der Absaugschlauch eine Federdrahtspirale enthält. Dabei ist der Absaugschlauch bevorzugt ein Spiralschlauch mit in die Schlauchwandung eingebetteter Federdrahtspirale.The Output pivotal position is further by the bending elasticity or influenced by the rigidity of the suction hose. In this Context is appropriate provided that the suction hose contains a spring wire spiral. there the suction hose is preferably a spiral hose with embedded in the hose wall Spring wire spiral.
Weitere zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Further expedient embodiments The invention are specified in the subclaims.
