The pivot bearings for inclination adjustment of the grip stirrup have a securing device with several securing positions.

Description

Die Erfindung betrifft eine Kehrmaschine mit wenigstens einer das Kehrgut zu einem Fangkorb fördernden Kehrwalze, die zumindest bereichsweise von einem Gehäuse umgeben ist, wobei zum Schieben der Kehrmaschine ein sich schräg nach oben zur Bedienperson hin erstreckender Griffbügel vorgesehen ist.The invention relates to a sweeper with at least one sweeping roller which conveys the sweepings to a grass catcher and which is at least partially surrounded by a housing, wherein a handle bracket which extends obliquely upwards towards the operator is provided for pushing the sweeper.

Derartige Kehrmaschinen dienen insbesondere zum Reinigen von größeren Hof- oder Hallenflächen, wobei das Kehrgut mittels einer oder mehrerer Kehrwalzen aufgenommen wird und in einen Fangkorb befördert wird. Hierbei sind Arbeitsleistungen von mehreren hundert Quadratmetern oder mehr auf kraftschonende Weise möglich, da die Kehrmaschine mit der etwa 80 cm breiten Kehrwalze auf einfache Weise über die zu kehrende Fläche geschoben wird. Zum Schieben der Kehrmaschine ist ein schräg nach oben zur Bedienperson hin erstreckender Griffbügel vorgesehen. Um eine möglichst direkte Krafteinleitung zu erreichen, ist der Griffbügel in Nähe von Abstütz- und Antriebsrädern für die Kehrwalze vorgesehen. Hierdurch ergibt sich insgesamt eine Gesamtlänge von ca. 1,5 bis 2 m, insbesondere, wenn am vorderen Ende der Kehrwalze noch rotierende Zuführbürsten oder Seitenbesen vorgesehen sind. Nach der Kehrarbeit nimmt somit die Kehrmaschine eine relativ große Grund- oder Stellfläche in Anspruch. Deshalb wurde bei derartigen Kehrmaschinen auch häufig der nach hinten auskragende Griffbügel mittels Steckverbindungen oder dgl. abmontiert. Dennoch nimmt die Kehrmaschine beispielsweise bei einer Kehrwalzenbreite von 80 cm noch nahezu 1 m² als Stellplatz ein. Zudem ist das Ab- und Wiederanschrauben des Griffbügels relativ arbeitsaufwendig, so daß darauf häufig verzichtet wird.Sweepers of this type are used in particular for cleaning larger courtyard or hall areas, the sweepings being picked up by means of one or more sweeping rollers and being conveyed into a collecting basket. Work performances of several hundred square meters or more are possible in a force-saving manner, since the sweeper with the approximately 80 cm wide brush roller is easily pushed over the surface to be swept. To push the sweeper, a handle bracket is provided that extends obliquely upward toward the operator. In order to achieve the most direct force possible, the handlebar is provided in the vicinity of support and drive wheels for the broom. This results in a total length of approximately 1.5 to 2 m, in particular if rotating feed brushes or side brushes are also provided at the front end of the sweeping roller. After sweeping, the sweeper takes up a relatively large floor space. For this reason, the rearward-projecting handle bar was frequently also dismantled by means of plug connections or the like in such sweepers. Nevertheless, with a sweeper roller width of 80 cm, the sweeper still occupies almost 1 m² as a parking space. In addition, unscrewing and re-screwing the handle bar is relatively labor intensive, so that it is often dispensed with.

Demzufolge liegt der Erfindung die Aufgabe zugrunde, eine Kehrmaschine zu schaffen, die in Aufbewahrungs- oder Abstellposition einen sehr geringen Platzbedarf aufweist, wobei zudem der Arbeitsaufwand zum Überführen in diese platzsparende Aufbewahrungsstellung reduziert werden soll.Accordingly, the object of the invention is to create a sweeper which, in the storage or storage position, requires very little space, and the work involved in transferring it to this space-saving storage position is also to be reduced.

Diese Aufgabe wird gelöst mit einer Kehrmaschine gemäß den Merkmalen des Patentanspruches 1.This object is achieved with a sweeper according to the features of claim 1.

Da in der Aufbewahrungsstellung der Kehrmaschine diese in aufrechter Ausrichtung aufgestellt ist, benötigt sie nur noch etwa ein Drittel oder ein Viertel der üblichen Stellfläche, so daß die Kehrmaschine in Art eines aufgestellten Koffers platzsparend verstaut werden kann. In dieser aufrechten Aufbewahrungsstellung ist die Kehrmaschine durch Abstützpunkte abgestützt, die durch die seitlichen Schwenklager des abgeklappten Griffbügels gebildet sind. Die beiden seitlichen Schwenklager sind hierbei im Bereich der Gehäuseoberkante und der Gehäuserückkante vorgesehen, so daß sich im Zusammenwirken mit der Gehäuserückseite, insbesondere einem damit verbundenen Fangkorbrahmen eine stabile Dreipunkt- oder Vierpunktabstützung ergibt. Hierbei ist von besonderem Vorteil, daß somit der Griffbügel nur noch umgeklappt werden muß und die Kehrmaschine aufgestellt wird, so daS kein arbeitsaufwendiges Abmontieren des Griffbügels erforderlich ist. Zudem ist von Vorteil, daß der obere Teil des Griffbügels in der abgeklappten Stellung an dem Fangkorb anliegt, so daß ein Herausfallen des nunmehr ebenfalls aufrechtstehenden Fangkorbes aus dem Gehäuse verhindert wird. Damit ist ein vorheriges Entleeren des z. B. halb gefüllten Fangkorbes nicht erforderlich, so daß auch in kürzeren Arbeitspausen die aufrechte Aufbewahrungsstellung auf einfache und schnelle Weise hergestellt werden kann.Since in the storage position of the sweeper this is set up in an upright orientation, it only needs about a third or a quarter of the usual footprint, so that the sweeper can be stowed away in a space-saving manner. In this upright storage position, the sweeper is supported by support points which are formed by the lateral pivot bearings of the folded handle bar. The two side swivel bearings are provided in the area of the upper edge of the housing and the rear edge of the housing, so that in cooperation with the rear of the housing, in particular an associated catch frame, there is a stable three-point or four-point support. It is particularly advantageous here that the handle only has to be folded down and the sweeper is set up, so that no labor-intensive removal of the handle is necessary. It is also advantageous that the upper part of the handle bar rests on the collecting basket in the folded position, so that the collecting basket, which is now also upright, is prevented from falling out of the housing. This is a previous emptying of the z. B. half-filled grass catcher is not required, so that the upright storage position can be produced in a simple and quick manner even in shorter breaks.

Weitere vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.Further advantageous refinements are the subject of the dependent claims.

Nachfolgend wird ein Ausführungsbeispiel anhand der Zeichnung näher erläutert und beschrieben. Hierin zeigen:

An exemplary embodiment is explained and described in more detail below with reference to the drawing. Show here:
Fig. 1
a side view of the sweeper in the working position;
Fig. 2
a side view of the sweeper in the upright storage position; and
Fig. 3
a view rotated by 90 ° on the top of the sweeper according to FIG. 2nd

In Fig. 1 ist eine Kehrmaschine 1 dargestellt, die wenigstens eine das auf dem Boden liegende Kehrgut aufnehmende Kehrwalze 2 aufweist und dieses im Überwurfprinzip in einen Fangkorb 3 fördert. Der Fangkorb 3 ist von einem Fangkorbrahmen 3a umgeben, der mit einem die Kehrwalze 2 zumindest teilweise umgebenden Gehäuse 4 verbunden bzw. einstückig ausgebildet ist. An dem Gehäuse 4 bzw. dem Fangkorbrahmen 3a ist ein unter etwa 30° schräg nach oben verlaufender Griffbügel 5 zum Schieben der Kehrmaschine 1 vorgesehen. Etwa bei einem Drittel der Länge des Griffbügels 5 sind zwei seitliche Schwenklager 6 vorgesehen, die dabei so angeordnet sind, daß sie sich etwa im Schnittpunkt der an die Gehäuseoberkante 4a und die Gehäuserückkante 4b gelegten Tangenten befinden.1 shows a sweeper 1 which has at least one sweeping roller 2 which receives the swept material lying on the floor and conveys it into a collecting basket 3 on the principle of throwing over. The grass catcher 3 is surrounded by a grass catcher frame 3 a, which is connected to a housing 4 which at least partially surrounds the sweeping roller 2 or is formed in one piece. Provided on the housing 4 or the catcher frame 3a is a handle 5 which extends at an angle of approximately 30 ° upwards for pushing the sweeper 1. Approximately one third of the length of the handle 5, two lateral pivot bearings 6 are provided, which are arranged so that they are located approximately at the intersection of the tangent to the upper housing edge 4a and the rear housing edge 4b.

Am vorderen Ende der Kehrmaschine 1 sind eine oder zwei Zuführbürsten 7 vorgesehen, die das Kehrgut in seitlicher Richtung zusammenfassen und der Kehrwalze oder dem Kehrwalzenpaar 2 zuführen. Die Kehrwalze(-n) ist/sind dabei über seitlich am Gehäuse 4 angeordnete Räder 8 abgestützt und zugleich angetrieben.At the front end of the sweeper 1, one or two feed brushes 7 are provided, which combine the sweepings in the lateral direction and feed the sweeper roller or the pair of sweeper rollers 2. The sweeping roller (s) is / are supported and driven at the same time via wheels 8 arranged on the side of the housing 4.

In Fig. 2 ist die Kehrmaschine gemäß Fig. 1 in aufrechter Aufbewahrungsstellung B gezeigt, wobei die Kehrmaschine 1 gegenüber der Betriebsstellung gemäß Fig. 1 um 90° gekippt wird. Wie ersichtlich, nimmt dabei die Kehrmaschine 1 nur noch etwa ein Viertel des Stellplatzes gegenüber der Grundfläche in Betriebsstellung ein. Hierdurch kann die Kehrmaschine 1 in aufrechter Aufbewahrungsstellung B beispielsweise an Wänden einfach aufgestellt werden. Dabei ist die Kehrmaschine 1 an den beiden seitlichen Schwenklagern 6 (vgl. auch Fig. 3) abgestützt, so daß sich eine standfeste Aufbewahrungsstellung B ergibt. Von besonderem Vorteil ist hierbei, daß der obere Teil 5a des Griffbügels 5 auf einfache Weise auf die Oberseite des Gehäuses 4 geklappt werden kann, wobei der Fangkorb 3 gegen Herausfallen gesichert ist. Hierbei können an den Anlagepunkten zwischen dem Fangkorb 3 und dem oberen Teil 5a des Griffbügels 5 Gummihülsen 9 vorgesehen sein, um eine sichere Halterung des Fangkorbes 3 innerhalb des Gehäuses 4 bzw. des Fangkorbrahmens 3a zu gewährleisten. Es sei darauf hingewiesen, daß der Fangkorbrahmen 3a als das am weitesten nach hinten herausstehende Teil des Gehäuses 4 sich in der Vertikalebene gemäß Fig. 1 bzw. in aufrechter Aufbewahrungsstellung B in Horizontalebene mit den Schwenklagern 6 befindet, so daß die aufrechtstehende Aufbewahrungsstellung B auch in vollständig freistehender Stellung der Kehrmaschine 1 gewährleistet ist.FIG. 2 shows the sweeper according to FIG. 1 in the upright storage position B, the sweeper 1 being tilted by 90 ° in relation to the operating position according to FIG. 1. As can be seen, the sweeper 1 occupies only about a quarter of the parking space in relation to the base in the operating position. As a result, the sweeper 1 can easily be set up in the upright storage position B, for example on walls. The sweeper 1 is supported on the two lateral pivot bearings 6 (see also FIG. 3), so that there is a stable storage position B. It is particularly advantageous here that the upper part 5a of the handle 5 can be easily folded onto the top of the housing 4, the catcher 3 preventing it from falling out is secured. Here, rubber sleeves 9 can be provided at the contact points between the grass catcher 3 and the upper part 5a of the handle 5 to ensure that the grass catcher 3 is held securely within the housing 4 or the grass catcher frame 3a. It should be noted that the grass catcher frame 3a, as the most rearwardly protruding part of the housing 4, is located in the vertical plane according to FIG. 1 or in the upright storage position B in the horizontal plane with the pivot bearings 6, so that the upright storage position B is also in completely free-standing position of the sweeper 1 is guaranteed.

Dies ist in der um 90° gedrehten Ansicht gemäß Fig. 3 auf die Kehrmaschine dargestellt, wobei insbesondere die Dreipunktabstützung durch die beiden seitlichen Schwenklager 6 und dem tiefsten Punkt (Wölbung als weiterer Abstützpunkt 3b) des Fangkorbrahmens 3a ersichtlich ist. Ebenso ist aus Fig. 3 ersichtlich, daß sich das obere Teil 5a des abgeklappten Griffbügels 5 zu dem in Betriebsstellung oberen Querholm hin verjüngt, so daß die hier oberen beiden Ecken des Fangkorbes 3 mit abgedeckt werden und somit ein Herausfallen des Fangkorbes 3 in der aufrechten Aufbewahrungsstellung B der Kehrmaschine verhindert wird. Somit ist für den Fangkorb 3 keine zusätzliche Verriegelung erforderlich, da in der Betriebsstellung gemäß Fig. 1 der Fangkorb ohnehin liegend in dem Fangkorbrahmen 3a angeordnet ist.This is shown in the view rotated by 90 ° according to FIG. 3 on the sweeper, in particular the three-point support through the two lateral pivot bearings 6 and the lowest point (curvature as a further support point 3b) of the catch frame 3a can be seen. It can also be seen from Fig. 3 that the upper part 5a of the folded handle 5 tapers towards the upper cross member in the operating position, so that the upper two corners of the catcher basket 3 are covered with and thus a falling out of the catcher basket 3 in the upright Storage position B of the sweeper is prevented. Thus, no additional locking is required for the grass catcher 3, since in the operating position according to FIG. 1 the grass catcher is arranged in the grass catcher frame 3 a anyway.

Bei den beiden Schwenklagern 6 ist zudem ein Druckknopf 6a schematisch angedeutet, der eine Arretiereinrichtung mit mehreren Raststellungen bildet, so daß der obere Teil 5a des Griffbügels 5 zumindest in den beiden in Fig. 1 und 2 dargestellten Stellungen einrastet und damit arretiert wird. Zudem ist in der Stellung gemäß Fig. 1 noch eine Neigungsverstellung des Griffbügels 5 vorgesehen, so daß dieser an die jeweilige Körpergröße der Bedienperson angepaßt werden kann. Derartige Arretiereinrichtungen 6a sind beispielsweise von Beschlägen für Dachfenster bekannt, so daß eine nähere Beschreibung entbehrlich ist. Wesentlich ist hierbei lediglich, daß der Druckknopf 6a im Zentrum des Schwenklagers 6 federbelastet ist und somit bei Betätigung ein Verstellen des oberen Teils 5a des Griffbügels 5 ermöglicht, während bei Loslassen des Druckknopfes 6a der Griffbügel 5 in der eingestellten Position arretiert wird. In zweckmäßiger Weise sind die beiden Schwenklager 6 rollenförmig ausgebildet, so daß eine einfache Unterbringung der Arretiereinrichtung 6a mit dem Druckknopf und beispielsweise einer Lochscheibe ermöglicht wird. Andererseits wird durch die rollenförmige Ausbildung des Schwenklagers 6 eine sichere Abstützung der Kehrmaschine 1 in aufgestellter Position B erreicht. Bevorzugt ist hierbei der Außenumfang des Schwenklagers 6 aus Kunststoff gebildet oder mit einem elastischen Gummimaterial versehen, so daß sich eine rutschfeste Auflage der Schwenklager 6 in der aufgestellten Aufbewahrungsstellung B der Kehrmaschine 1 ergibt. Der untere Teil 5b des Griffbügels 5 ist hierbei an beiden Seiten der Kehrmaschine 1 mit Schraub- oder Steckverbindungen am Fangkorbrahmen 3a direkt hinter den Abstützrädern 8 befestigt. Am Fangkorbrahmen 3a ist zudem wenigstens eine lenkbare Rolle 10 zur Abstützung der Kehrmaschine 1 in Arbeitsstellung gemäß Fig. 1 befestigt.In the two pivot bearings 6, a push button 6a is also indicated schematically, which forms a locking device with several locking positions, so that the upper part 5a of the handle 5 engages at least in the two positions shown in FIGS. 1 and 2 and is thus locked. In addition, an inclination adjustment of the handle 5 is provided in the position shown in FIG. 1, so that it can be adapted to the respective body size of the operator. Locking devices 6a of this type are known, for example, from fittings for roof windows, so that a more detailed description is unnecessary. The only important thing is that the push button 6a in the center of the pivot bearing 6 is spring-loaded and thus allows an adjustment of the upper part 5a of the handle 5 when actuated, while the handle 6 is locked in the set position when the push button 6a is released. The two pivot bearings 6 are expediently roller-shaped, so that the locking device 6a can be easily accommodated with the push button and, for example, a perforated disk. On the other hand, the roller-shaped design of the pivot bearing 6 provides secure support for the sweeper 1 in the installed position B. Preferably, the outer circumference of the pivot bearing 6 is formed from plastic or provided with an elastic rubber material, so that there is a non-slip support of the pivot bearing 6 in the stored storage position B of the sweeper 1. The lower part 5b of the handle 5 is fastened on both sides of the sweeper 1 with screw or plug connections on the collecting frame 3a directly behind the support wheels 8. At least one steerable roller 10 for supporting the sweeper 1 in the working position according to FIG. 1 is also attached to the catcher frame 3a.
