Abstract

The sweeper has a carrier plate (1) to which the mountings (4) for the drive motor (2,3) are directly attached, together with mountings (6) for two rollers (7) positioned at the rear of the sweeper. The rotating cleaning brush (10) is mounted at the front. The mountings (11) for the cleaning brush (10) are fixed directly to the housing (9) enclosing the carrier plate (1). The stator (2) of the drive motor (2,3) is also directly mounted on the carrier plate. The mounting of the cleaning brush (10) to the housing (9) allows the size of the carrier plate (1) to be limited to the area of the carpet sweeper base in which the rear rollers (7) and the motor lie (2,3).

Description

Teppichkehrvorsatzgerät Carpet sweeping attachment

Die Erfindung betrifft ein Teppichkehrvorsatzgerät gemäß dem Oberbegriff des ersten Patentanspruchs.The invention relates to a carpet sweeping attachment according to the preamble of the first claim.

Bei einem bekannten Teppichkehrvorsatzgerät dieser Art (DE-OS 27 54 583) sind auf einer die Grundfläche des Gerätes abdeckenden Tragplatte ein eigenständiger Antriebsmotor und über Schwingarme eine Kehrwalze gelagert, während an der Unterseite als Stützelemente Gleitflächen vorgesehen sind. Der Antriebsmotor ist dabei in einem eigenen Gehäuse gelagert und damit auf der Tragplatte festgesetzt. Nachdem die Tragplatte dabei die auf die Gleitflächen einwirkenden Kräfte als auch gleichzeitig die thermischen Belastungen vom Antriebsmotor her aufnehmen muß, ist für ihre Herstellung ein hochwertiges und damit teueres Material sowie ein entsprechend großes Herstellungswerk zeug erforderlich.In a known carpet sweeping attachment of this type (DE-OS 27 54 583) are independent on a support plate covering the base of the device Drive motor and a roller brush mounted via swing arms, while at the bottom sliding surfaces are provided as support elements. The drive motor is in one own housing stored and thus fixed on the support plate. After the support plate the forces acting on the sliding surfaces as well as the thermal forces at the same time Must absorb loads from the drive motor, is a high quality for their production and thus expensive material and a correspondingly large manufacturing tool required.

Der Erfindung liegt die Aufgabe zugrunde bei einem Teppichkehrvorsatzgerät gemäß dem Oberbegriff des Patentanspruchs Maßnahmen zu treffen, durch welche die Tragplatte in ihrer Größe lediglich einen Teil der Gerätegrundfläche zu überdecken braucht.The invention is based on the object of a carpet sweeping attachment according to the preamble of the claim to take measures through which the support plate only needs to cover part of the device base area in terms of size.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des Patentanspruchs.The solution to this problem takes place according to the invention by the characterizing Features of the claim.

Bei der Ausgestaltung gemäß der Erfindung kann sich die Größe der Tragplatte aus hochwertigem und damit teuerem Material auf die Größe entsprechend dem Motor und den Stützrollen beschränken und es braucht auch darüberhinaus kein eigenes Motorgehäuse angewandt werden. Dabei wird die Belastung, die durch mechanische Kräfte von den Rolaie len und durchjerhöhten Temperaturen am Motor und seinen Lagern auftreten, unmittelbar von der Tragplatte aufgenommen.In the embodiment according to the invention, the size of the Support plate made of high-quality and therefore expensive material according to the size limit the motor and the support rollers and there is no need beyond that own motor housing can be used. Thereby the load caused by mechanical Forces from the rollers and increased temperatures on the engine and its bearings occur, recorded directly from the support plate.

Die Erfindung ist nachfolgend anhand der Zeichnung eines Ausführungsbeispiels näher erläutert, wobei ein Teppichkehrvorsatzgerät mit an der Oberseite aufgeschnittenem Gehäuse dargestellt ist.The invention is described below with reference to the drawing of an exemplary embodiment explained in more detail, with a carpet sweeping attachment with cut open on the top Housing is shown.

Auf einer Tragplatte 1 ist ein Stator 2 eines Antriebsmotors festgesetzt, dessen Anker 3 unmittelbar in Lagern 4 gehalten ist, die gegen einstückig mit der Tragplatte 1 verbundene Stützen mittels Spannlaschen 5 gespannt sind.A stator 2 of a drive motor is fixed on a support plate 1, whose armature 3 is held directly in bearings 4, which against integral with the Support plate 1 connected supports are tensioned by means of clamping straps 5.

Hierdurch werden die mechanischen Kräfte und auch die thermischen Belastungen des Antriebsmotors unmittelbar auf die Tragplatte 1 übertragen. Gleichzeitig sind an die Tragplatte 1 Radkästen 6 angeformt, in welchen Stützrollen 7 drehbar gelagert sind. Die Stützrollen 7 ragen an der zur bearbeitenden Fläche hingewandten Unterseite der Tragplatteiüber deren Ebene hinaus. Die Stützrollen 7 nehmen daher alle im Betrieb auftretenden Belastungen auf, die insbesondere beim Überfahren von Schwellen oder dergl.This reduces the mechanical forces as well as the thermal Loads of the drive motor are transferred directly to the support plate 1. Simultaneously are formed on the support plate 1 wheel arches 6, in which support rollers 7th are rotatably mounted. The support rollers 7 protrude on the surface facing the working surface Underside of the support plate beyond its level. The support rollers 7 therefore take all loads occurring during operation, especially when driving over Thresholds or the like.

Hindernissen eine starke Beanspruchung der Tragplatte 1 bewirken. Daneben ist an der Tragplatte 1 auch eine Halbschale 8 für ein Gelenk vorgesehen, durch welches die angesaugte staubbeladene Luft abgesaugt werden kann.Obstacles cause heavy stress on the support plate 1. In addition, a half-shell 8 for a joint is provided on the support plate 1, through which the sucked in dust-laden air can be sucked out.

Die Tragplatte 1 ist an ihrer den Antriebsmotor tragenden Seite von einem Gehäuse 9 überdeckt, das sich über die Grundfläche der Tragplatte 1 hinaus erstreckt und in welchem vor der Tragplatte eine Kehrwalze 10 mittels Lagern 11 drehbar gelagert ist. Die Kehrwalze 10 ist mittels eines Riemens 12 mit der Welle des Antriebsmotors 2,3 gekuppelt.The support plate 1 is on its side carrying the drive motor of a housing 9, which extends beyond the base of the support plate 1 extends and in which in front of the support plate a roller brush 10 by means of bearings 11 is rotatably mounted. The main brush 10 is connected to the shaft by means of a belt 12 of the drive motor 2.3 coupled.

Die aus hochwertigem Kunststoff im Spritzverfahren hergestellte Tragplatte1/ist gleichzeitig mit einer Labyrinthführung 13 ausgestattet, die aus mehreren gegeneinander gerichteten Stegen besteht, zwischen welchen ein elektrisches Anschlußkabel 14 in Mäanderform hindurchgeführt wird. Die Tragplatte i ist auch mit Halterungen 15 für Lötstützpunkte 16 versehen, an die einerseits die Anschlüsse des elektrischen Kabels 14 und andererseits die elektrischen Anschlüsse des Motors 2,3 angelötet sind.The support plate1 / is manufactured from high-quality plastic in an injection molding process at the same time equipped with a labyrinth guide 13, which consists of several against each other directed webs exists, between which an electrical connection cable 14 in Meander shape is passed. The support plate i is also provided with brackets 15 for Provided soldering posts 16, on the one hand the connections of the electrical cable 14 and on the other hand the electrical connections of the motor 2,3 are soldered.

Auch trägt die Tragplatte 1 nicht dargestellte Halterungen für Kohleköcher, in welche Kohlebürsten für den Kollektor des Motors 2,3 unmittelbar eingesetzt werden.The support plate 1 also carries brackets, not shown, for charcoal quivers, in which carbon brushes are used directly for the collector of the motor 2,3.

Bei dieser Ausgestaltung muß somit das Material für die Tragplatte 1 nicht nur elektrisch und thermisch hochwertig sein, sondern auch hohe mechanische Belastungen aushalten. Die Tragplatte 1 ist daher in ihrer Größe so bemessen, daß sie lediglich die Funktionselemente aufnimmt, an welchen erhöhte Belastungen auftreten.In this embodiment, the material for the support plate must therefore 1 not only be of high electrical and thermal quality, but also of high mechanical quality Endure loads. The support plate 1 is therefore dimensioned in size so that it only accommodates the functional elements on which increased loads occur.
