Definitions
- the invention relates to a height adjustment according to the preamble of claim 1.
- a height adjustment for the roller brush is therefore necessary for higher quality carpet sweepers in order to optimally adjust the roller brush to the different pile heights of the carpets. In many cases it is also desirable to clean completely smooth floors with a carpet sweeper.
- a height adjustment of the roller brush for carpet sweepers is known from DE-OS 31 00 497. With this height adjustment, the roller brush remains constant in relation to the housing, while the drive wheels are locked relative to it. This requires a rather complex storage of the drive wheels in a wheel arch. This construction is mainly suitable for large, luxurious floor sweepers.
- the object of the invention is to provide a height adjustment for a roller brush, which is of extremely compact construction, consists of a few individual parts and is also suitable for returners.
- the carpet sweeper consists essentially of a housing 1, a handle bracket 2 with handle 3, a roller brush 4, drive wheels 5 and a height adjustment 6.
- the other components of the carpet sweeper are of no importance for the invention, so that it will not be discussed further.
- the height adjustment is composed of a U-shaped adjusting bracket 7, which is mounted in the housing 1 with bends 10 formed on the free ends 8 of the legs 9, an adjusting slide 11, a spring 12 connected thereto and the run-up bevels 13 on the housing 1.
- the roller brush 4 is acted upon by the legs 9 of the adjustment bracket 7 with the interposition of a brush bridge 14.
- the adjusting slide 11 is mounted in a housing part 15 which is arranged interchangeably in the housing 1.
- the EinsteLLschieber 11 is locked with a mushroom-shaped cam 16 on the spring 12.
- the VersteLLweg the adjustment slide 11 is given by a slot 17 in the housing part 15.
- the spring 12 is designed as a leaf spring and is provided at both ends with an eye 18 which surrounds the apex part 19 of the adjustment bracket 7 in a U-shape.
- Guide surfaces 20 are formed on the eyes 18 and slide on the run-up slopes 13 on both sides.

Description
Die Erfindung bezieht sich auf eine HöheneinsteLLung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a height adjustment according to the preamble of
Eine HöheneinsteLLung für die Walzenbürste ist bei höherwertigen Teppichkehrern deshalb erforderlich, um die WaLzenbürste optimal auf die ünterschiedlichen FLorhöhen der Teppiche einzustellen. VieLfach ist es auch erwünscht, mit einem Teppichkehrer gänzlich glatte Böden zu reinigen.A height adjustment for the roller brush is therefore necessary for higher quality carpet sweepers in order to optimally adjust the roller brush to the different pile heights of the carpets. In many cases it is also desirable to clean completely smooth floors with a carpet sweeper.
Durch die DE-OS 31 00 497 ist eine HöheneinsteLLung der Walzenbürste für Teppichkehrer bekannt. Bei dieser Höheneinstellung behält die WaLzenbürste ihre Lage gegenüber dem Gehäuse konstant, während die Antriebsräder relativ dazu versteLLt werden. Dies erfordert eine recht aufwendige Lagerung der Antriebsräder in einem Radkasten. Diese Konstruktion bietet sich hauptsächlich für große, Luxuriöse Boderkehrmaschinen an.A height adjustment of the roller brush for carpet sweepers is known from DE-OS 31 00 497. With this height adjustment, the roller brush remains constant in relation to the housing, while the drive wheels are locked relative to it. This requires a rather complex storage of the drive wheels in a wheel arch. This construction is mainly suitable for large, luxurious floor sweepers.
Aufgabe der Erfindung ist es, eine HöheneinsteLLung für eine WaLzenbürste zu schaffen, die äußerst kompakt gebaut, aus wenigen EinzeLteiLen besteht und auch für KLeinkehrer geeignet ist.The object of the invention is to provide a height adjustment for a roller brush, which is of extremely compact construction, consists of a few individual parts and is also suitable for returners.
Diese Aufgabe wird mit den kennzeichneden Merkmalen des Anspruchs 1 gelöst. Für diese HöheneinsteLLung wird neben dem U-förmigen Verstellbügel lediglich ein Einstellschieber und eine Feder benötigt. Die Montage ist denkbar einfach, weil die TeiLe LedigLich eingehängt beziehungsweise eingektipst werden; die AufLaufschrägen sind direkt am Gehäuse beziehungsweise einem Gehäuseteil angeformt. Die Einheit baut sehr flach, was der Handlichkeit eines Kehrers sehr entgegen kommt. Der Kehrer kann insgesamt äußerst flach gehalten werden.This object is achieved with the characterizing features of
Weitere Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. So dient die zusätzliche Anbringung von FührungsfLächen und U-förmigen Augen an der Feder der zusätzlichen Betriebssicherheit. Ein Herausspringen der Feder wird dabei zuverlässig verhindert.Further embodiments of the invention can be found in the subclaims. The additional attachment of guide surfaces and U-shaped eyes on the spring serves for additional operational safety. The spring is reliably prevented from jumping out.
Da die gesamte Einheit nur wenig Raum benötigt, ist es besonders vorteilhaft, den Gehäuseteil, der diese Einheit trägt und beeinflußt, austauschbar zu gestalten. Dadurch wird die MögLichkeit geschaffen, eine Teppichkehrerbaureihe aufzustellen. Soll der Kehrer vereinfacht werden, wird LedigLich der GehäuseteiL mit der Einheit und der U-förmige Versteellbügel weggelassen und durch eine um diesen TeiL vergrößerte Abdeckung ersetzt. ALLe übrigen BauteiLe des Teppichkehrers können identisch verwendet werden. Dies ermöglicht es, trotz Modellvielfalt mit den wesentlichen BauteiLen hohe StückzahLen auf geringerer Kostenbasis zu fahren.Since the entire unit takes up little space, it is particularly advantageous to make the housing part that supports and influences this unit interchangeable. This creates the opportunity to set up a carpet sweeper series. If the sweeper is to be simplified, the housing part with the unit and the U-shaped adjustment bracket are simply omitted and replaced by a cover enlarged by this part. All other parts of the carpet sweeper can be used identically. Despite the wide range of models, this makes it possible to drive high quantities with the essential components on a lower cost basis.
Ein AusführungsbeispieL der Erfindung wird im folgenden an Hand der Zeichnungen näher erLäutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawings.

Der Teppichkehrer besteht äußerlich im wesentlichen aus einem Gehäuse 1, einem Stielbügel 2 mit Stiel 3, einer Walzenbürste 4, AntriebsLaufräder 5 und einer Höheneinstellung 6. Die weiteren BauteiLe des Teppichkehrers sind für die Erfindung ohne Bedeutung, so daß darauf nicht weiter eingegangen wird.The carpet sweeper consists essentially of a
Die HöheneinsteLLung setzt sich aus einem U-förmigen VersteLLbügeL 7, der mit an den freien Enden 8 der Schenkel 9 angeformten AbwinkLungen 10 im Gehäuse 1 geLagert ist, einem Einstellschieber 11, einer damit verbundenen Feder 12 und den Auflaufschrägen 13 am Gehäuse 1 zusammen. Die Walzenbürste 4 wird unter Zwischenschaltung einer Bürstenbrücke 14 von den Schenkel 9 des Verstellbügels 7 beaufschlagt.The height adjustment is composed of a U-shaped adjusting
Der Einstellschieber 11 ist in einem Gehäuseteil 15, das austauschbar im Gehäuse 1 angeordnet ist, geLagert. Der EinsteLLschieber 11 ist dabei mit einem pilz-förmigen Nocken 16 auf der Feder 12 verrastet. Der VersteLLweg des Einstellschiebers 11 ist durch einen SchLitz 17 im GehäuseteiL 15 gegeben. Die Feder 12 ist als BLattfeder ausgebildet und an ihren beiden Enden jeweils mit einem Auge 18 versehen, das den Scheitelteil 19 des Verstellbügels 7 U-förmig umfaßt. An den Augen 18 sind FührungsfLächen 20 angeformt, die beidseitig auf den Auflaufschrägen 13 gleiten.The adjusting
Durch Verschieben des Einstellschiebers 11 in Richtung 21 aus der SteLLung gemäß Figur 2 a) wird die tiefste SteLLung der Walzenbürste 4 gemäß Figur 2 b) erreicht. Die Schenkel 9 machen dabei eine Winkelbewegung 22 und verschieben die Bürstenbrücke in die strich-punktiert gezeichnete SteLLung 23 in Figur 3.By moving the
