Description

Die bisher bekannten elektrischen Bohnervorrichtungen, bei denen gewöhnlich ein Elektromotor unmittelbar das sich drehende Bürstoder Polierwerkzeug antreibt, leiden an dem Übelstand, daß, wenn die von dem Werkzeug bestrichene Fläche eine einer wirtschaftlichen Arbeitsweise angepaßte Größe besitzen soll, der Motor unverhältnismäßig schwer wird, da entsprechend der Größe der bestrichenenThe previously known electric polishing devices, in which usually an electric motor directly driving the rotating brushing or polishing tool suffer from the drawback that when the tool the coated area should have a size adapted to an economical way of working, the engine becomes disproportionately heavy, because according to the size of the coated

to Fläche auch die Größe des Werkzeuges und damit dessen Reibungswiderstand am Fußboden wächst. Die Folge ist eine erhebliche Verteuerung der Bohnervorrichtung und ein vom wirtschaftlichen Standpunkte zu großer Stromverbrauch.to area also the size of the tool and so that its frictional resistance on the floor increases. The consequence is considerable The polishing device became more expensive and too big from an economic point of view Power consumption.

Die Erfindung soll diesen Übelstand dadurch beseitigen, daß das Burst- oder Polierwerkzeug exzentrisch gelagert ist. Auf diese Weise kann, insbesondere, wenn die wirksame Fläche des Werkzeuges, vor allem der Bürste, ringförmig gestaltet wird, das Werkzeug selbst verhältnismäßig klein gehalten und dabei doch eine große Fläche bestrichen werden. Der Motor kann also viel kleiner als bisher gemacht werden. Außerdem kommt noch hinzu, daß die .Bearbeitung des Fußbodens eine gleichmäßigere ist, da alle wirksamen Teile des Werkzeuges jeden Augenblick ihre Lage mit Bezug auf die Bewegungsrichtung der gesamten Bohnervorrichtung verändern, so daß eine Streifenbildung auf dem Fußboden ausgeschlossen ist.The invention is intended to eliminate this drawback by the fact that the burst or polishing tool is eccentrically mounted. In this way, especially when the effective surface of the tool, especially the brush, is designed ring-shaped, the tool itself is kept relatively small and thereby but a large area can be coated. So the engine can be much smaller than before be made. In addition, the processing of the floor a more uniform one, since all the effective parts of the tool are theirs at every moment Change the position in relation to the direction of movement of the entire polishing device, so that streaking on the floor is impossible.

Die Zeichnung veranschaulicht beispielsweise eine Ausführungsform der Erfindung. , Abb. ι ist ein Querschnitt durch die elektrische Bohnervorrichtung quer zur Bewegungsrichtung, Abb. 2 eine Unteransicht und Abb. 3 eine Gesamtansicht der Bewegungsebene. The drawing illustrates, for example, an embodiment of the invention. , Fig. Ι is a cross section through the electric polishing device transversely to the direction of movement, Fig. 2 is a view from below and Fig. 3 is an overall view of the plane of movement.

Die Bohnervorrichtung besteht aus einem auf vier Rädern oder Rollen 1 laufenden Wagen 2, der an seiner Unterseite 3 rahmenartig gestaltet ist. Dieser Wagen trägt oben, durch ein Gehäuse 4 geschützt, den Elektromotor 5, der auf der Mittelfläche 6 des Wagens durch Bolzen 7 befestigt ist. Die Welle 8 dieses Motors ist einerseits im Scheitel des Gehäuses 4, anderseits in der Zwischenwand 6 gelagert und trägt mittels eines Gewindes o. dgl. 9 auswechselbar die Grundplatte 10 des Bohnerwerkzeuges. In dem dargestellten Beispiel besteht dieses aus einer Ringhürste 11, die mittels Zapfen 12 in Bohrungen 13 der Grundplatte 10 gegen den Druck einer Blattfeder 14 gelagert und die mittels federnder, geschlitzter Klappscharniere 15 in die Zapfen 16 an der Bürste eingreifen, gegen ein Herausfallen gesichert ist. Werden die Scharniere 15 hochgeklappt, so kann die Bürste 11 aus der Grundplatte 10 herausgenommen und beispielsweise durch ein mit einer Filzfiäche versehenes Polierwerkzeug ersetzt werden. Die Grundplatte 10 und damit die Bürste 11 sind exzentrisch zur Welle 8 des Elektromotors 5 gelagert, so daß sie trotz verhältnismäßiger Kleinheit eine große Fläche zu bestreichen vermögen. Zur Bewegung des Wagens 2 dient ein fest oder gelenkig mit diesem verbundener Handgriff 17. Die Stromzuführung zum Motor geschieht mit Hilfe des Kabels 18.The polishing device consists of a carriage 2 running on four wheels or rollers 1, which is designed like a frame on its underside 3. At the top, protected by a housing 4, this carriage carries the electric motor 5, which is fastened to the central surface 6 of the carriage by bolts 7. The shaft 8 of this motor is mounted on the one hand in the apex of the housing 4, on the other hand in the partition 6 and carries the base plate 10 of the polishing tool by means of a thread or the like 9 exchangeably. In the example shown, this consists of a ring brush 11, which is mounted against the pressure of a leaf spring 14 by means of pins 12 in bores 13 of the base plate 10 and which engage in the pins 16 on the brush by means of resilient, slotted hinges 15, is secured against falling out . If the hinges 15 are folded up, the brush 11 can be removed from the base plate 10 and replaced, for example, by a polishing tool provided with a felt surface. The base plate 10 and thus the brush 11 are mounted eccentrically to the shaft 8 of the electric motor 5, so that they are able to cover a large area despite their relatively small size. A handle 17 connected to it in a fixed or articulated manner is used to move the carriage 2. Power is supplied to the motor with the aid of the cable 18.
