Description

Elektrobohner Die Erfindung betrifft einen Elektrobohner, insbesondere von der Art, bei dem an der Unterseite einer waagerechten Tragplatte mittels Kopfschrauben in Schlitzen geführte Schieber für die Lagerzapfen der drehbaren Bürstentragscheiben, die durch nvischen die Schieber gespannte Federn gegen den Reibradtrieb des auf der Tragplatte angeordneten Antriebsmotors gedrückt werden, vorgesehen sind.Electric beater The invention relates to an electric beater, in particular of the type in which on the underside of a horizontal support plate by means of head screws slides guided in slots for the bearing journals of the rotating brush support disks, the springs tensioned by the slider against the friction drive of the the support plate arranged drive motor are pressed, are provided.

Das Neue der Erfindung besteht darin, daß die Tragplatte gleichzeitig unmittelbar als Träger für den Gerätestiel dient.The novelty of the invention is that the support plate at the same time serves directly as a carrier for the device handle.

Durch die Verwendung der Tragplatte gleichzeitig unmittelbar als Träger für den Gerätestiel werden von dieser nicht nur die aus der Bürstenantriebseinrichtung, sondern auch die aus der Handhabung des Elektrobohners mittels des Gerätestiels kommenden Beanspruchungen aufgenommen. Dadurch ist das äußere Bohnergehäuse von diesen Beanspruchungen entlastet. Das Gehäuse kann infolgedessen dünnwandig und gegebenenfalls aus Kunststoff hergestellt sein.By using the support plate at the same time directly as a carrier for the device handle, not only those from the brush drive device, but also from handling the electric polisher using the device handle coming stresses included. This means that the exterior floor polisher is off relieves these stresses. As a result, the housing can be thin-walled and possibly made of plastic.

Auf der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes im senkrechten Schnitt dargestellt.The drawing shows an example of an embodiment of the subject matter of the invention shown in vertical section.

Der Elektrobohner enthält als Haupttragteil eine Tragplatte i, bestehend aus einer durch aufgebogene Ränder 2 verstärkten Blechplatte. Auf der Platte i ist ein Elektromotor 3 angeordnet, der mit einem Reibradtrieb 5 durch eine Öffnung a dieser Platte nach unten ragt. An der Unterseite der Tragplatte i ist mittels Kopfschrauben 6 je ein Schieber 7 in Schlitzen S geführt. Die Schieber 7 tragen an ihrer Unterseite Lagerzapfen, auf welchen Trag- und Antriebsscheiben 9 für Bohnerbürsten i o drehbar angeordnet sind. Zwischen die Schieber; sind Zugfedern i i gespannt, durch welche die Antriebsscheiben 9 mit ihrem Umfang an den Umfang des Reibradtriebes 5 gedrückt und dadurch bei laufendem Motor 3 gedieht werden.The main supporting part of the electric beater is a supporting plate i, consisting made of a sheet metal plate reinforced by upturned edges 2. On the plate i is an electric motor 3 is arranged, which with a friction wheel drive 5 through an opening a this plate protrudes downwards. On the underside of the support plate i is cap screws 6 a slide 7 each guided in slots S. The slide 7 wear on their underside Bearing journals on which support and drive disks 9 for floor polishing brushes can be rotated are arranged. Between the slide; tension springs i i are tensioned by which the drive disks 9 are pressed with their periphery against the periphery of the friction wheel drive 5 and are thereby rotated with the engine 3 running.

An der Oberseite der Tragplatte i sind beiderseits Gelenkaugen 12 umgebogen. An ihnen ist ein Gerätestielbügel13 mittels Gelenkschrauben 14 angeschlossen. Dadurch sind alle eine Beanspruchung verursachenden Teile des Elektrobohners an der Tragplatte i vereinigt, und das äußere Gehäuse 15 ist auf diese Weise von diesen Beanspruchungen entlastet.Articulated eyes 12 are located on both sides on the upper side of the support plate i bent over. A device handle bracket 13 is connected to them by means of pivot screws 14. This means that all parts of the electric polisher that are causing stress are on the support plate i is united, and the outer case 15 is in this way therefrom Stress relieved.

Das Gehäuse 15 sitzt mit einem unteren Rand 16 seines mittleren, den Motor 3 umfassenden Teiles auf der Tragplatte i auf. Es weist in seiner Deckwand 23 Durchbrechungen 18 zum Durchtritt der Anschlußaugen 12 für den Gerätestielbügel13 auf. Außerdem weist es in der Deckwand 23 Löcher 22 auf, durch welche die oberen Verlängerungen i9 der Schieb erführungsschrauben 6 ragen. Auf nabenartige Randverstärkungen 2o der genannten Löcher 22 setzen sich die auf die Schraubenverlängerungen i9 aufgeschraubten gerändelten Muttern 21 auf.The housing 15 is seated with a lower edge 16 of its central part comprising the motor 3 on the support plate i. In its top wall 23 it has openings 18 for the connecting eyes 12 for the device handle bar 13 to pass through. It also has holes 22 in the top wall 23 through which the upper extensions i9 of the sliding guide screws 6 protrude. The knurled nuts 21 screwed onto the screw extensions 19 sit on the hub-like edge reinforcements 20 of the aforementioned holes 22.
