Description

Die Erfindung bezieht sich auf eine über den zu reinigenden Boden verfahrbare Bodenreinigungsmaschine mit einer das Chassis, die Räder, mindestens eine Antriebsanordnung, mindestens einen Behälter für Reinigungsflüssigkeit und eine Verkleidung aufweisenden Maschineneinheit, einem an der Maschineneinheit angebrachten, mindestens eine drehend antreibbare Bürste aufweisenden Reinigungsaggregat, einer Einrichtung zum Aufbringen von Reinigungsflüssigkeit auf den zu reinigenden Boden und einem Saugfuß zum Aufsaugen von verbrauchter Reinigungsflüssigkeit vom Boden, der um mindestens eine sich im Wesentlichen senkrecht zum Boden erstreckende Achse schwenkbar an der Maschineneinheit angelenkt ist, so dass er in seiner abgesenkten Sauglage der Kurvenfahrt der Bodenreinigungsmaschine folgend um die mindestens eine Achse schwenkt, und der in eine angehobene Transportlage bewegbar ist, wobei der Saugfuß in seiner sich bei Geradeausfahrt mit abgesenktem Saugfauß ergebenden Mittelstellung zu beiden Seiten der Maschineneinheit über diese vorsteht und dieser Überstand sich beim Verschwenken aus der Mittelstellung zumindest an einer Seite, vorzugsweise an beiden Seiten der Maschineneinheit verringert, und wobei die Verschwenkung des Saugfußes aus der Mittelstellung in beiden Richtungen bis in eine jeweilige Endstellung erfolgen kann.The invention relates to a floor cleaning machine which can be moved over the floor to be cleaned and has a cleaning unit which has the chassis, the wheels, at least one drive arrangement, at least one container for cleaning fluid and a panel, a cleaning unit attached to the machine unit and having at least one brush which can be driven in rotation. a device for applying cleaning liquid to the floor to be cleaned and a suction for sucking spent cleaning liquid from the ground, which is hinged to at least one substantially perpendicular to the ground axis extending pivotally mounted on the machine unit, so that in its lowered suction position of the cornering following the floor cleaning machine about the at least one axis pivots, and which is movable in a raised transport position, wherein the squeegee in his resulting when driving straight with lowered Saugfauß center position projecting on both sides of the machine unit on this and this supernatant is reduced when pivoting from the center position at least on one side, preferably on both sides of the machine unit, and wherein the pivoting of the squeegee from the center position can be made in both directions to a respective end position.

Bodenreinigunsmaschinen mit einem derartigen Grundaufbau sind sowohl als Aufsitzmaschinen ( DE-A-102 21 353 ) als auch als handgeführte Maschinen ( EP-B-0 398 393 ) bekannt und werden im großen Umfang bei der Bodenreinigung von gewerblichen Räumen eingesetzt. Dabei kommt es vor, dass die Bodenreinigungsmaschine von einem Raum in einen anderen gefahren werden muss, wozu sie durch Durchlässe oder Türöffnungen bewegt wird, deren Breite zwar größer als die Maschineneinheit, jedoch deutlich geringer als die sich infolge des in der Mittelstellung befindlichen Saugfußes ergebende Maximalbreite der Bodenreinigungsmaschine ist.Floor cleaning machines with such a basic structure are both as Aufsitzmaschinen ( DE-A-102 21 353 ) as well as hand-operated machines ( EP-B-0 398 393 ) and are widely used in the floor cleaning of commercial premises. It happens that the floor cleaning machine must be moved from one room to another, for which it is moved through passages or door openings, the width of which, although larger than the machine unit, but significantly lower than that due to the center position Suction foot resulting maximum width of the floor cleaning machine is.

Selbst wenn bei einer solchen Bodenreinigungsmaschine das Reinigungsaggregat nicht vollständig innerhalb der Breitenabmessung der Maschineneinheit angeordnet ist, sondern ein Teil des Reinigungsaggregats etwas seitlich über die Maschineneinheit vorsteht, kann die Bedienungsperson diesen im vorderen Bereich der Bodenreinigungsmaschine verhältnismäßig leicht durch schräges Anfahren der Türöffnung durch diese hindurch führen und dann in gerader Ausrichtung der Maschineneinheit weiter durch die Türöffnung fahren. Der seitliche Überstand des sich in der Mittelstellung befindlichen Saugfußes, der im übrigen normalerweise in seiner angehobenen Transportlage durch eine Rückstellkraft in dieser Mittelstellung gehalten wird, erschwert eine solche Durchfahrt jedoch erheblich oder macht sie häufig unmöglich. Es ist daher in den meisten Fällen erforderlich, dass die Bedienungsperson den Saugfuß abmontiert, die Bodenreinigungsmaschine durch die Türöffnung in den nächsten zu reinigenden Raum verfährt und dort den Saugfuß wieder montiert. Dieser Ablauf ist umständlich und zeitraubend.Even if in such a floor cleaning machine, the cleaning unit is not completely disposed within the width dimension of the machine unit, but a part of the cleaning unit protrudes slightly laterally over the machine unit, the operator can relatively easily lead this in the front of the floor cleaning machine by obliquely starting the door opening therethrough and then continue in the straight alignment of the machine unit through the door opening. The lateral projection of the located in the center position squeegee, which is otherwise held in the rest normally in its raised transport position by a restoring force in this middle position, such a passage difficult, however, or makes them often impossible. It is therefore necessary in most cases that the operator removes the squeegee, moves the floor cleaning machine through the door opening in the next room to be cleaned and there reassembled the squeegee. This process is cumbersome and time consuming.

Es ist Aufgabe der Erfindung, eine Bodenreinigungsmaschine so zu verbessern, dass das Durchfahren von verhältnismäßig engen Durchgängen oder Türöffnungen trotz des in seiner Mittelstellung seitlich ausladenden Saugfußes möglich wird.It is an object of the invention to improve a floor cleaning machine so that the passage of relatively narrow passages or door openings in spite of the laterally in its central position sweeping suction is possible.

Zur Lösung dieser Aufgabe wird eine Bodenreinigungsmaschine der eingangs erwähnten Art erfindungsgemäß derart ausgestaltet, dass der Saugfuß in der Transportlage durch Verschwenkung aus der Mittelstellung zumindest in einer Richtung in eine Manövrierstellung bringbar und in dieser gegen Verschwenkung um die mindestens eine Achse verriegelbar ist.To solve this problem, a floor cleaning machine of the type mentioned is inventively designed such that the squeegee in the transport position by pivoting from the center position at least in one direction in a maneuvering position and lockable in this against pivoting about the at least one axis.

Etwa durch ein manuell erfolgendes Verschwenken des in seiner angehobenen Transportlage befindlichen Saugfußes gegen die ihn üblicherweise in der Mittelstellung haltende Rückstellkraft kann die Bedienungsperson eine Verriegelung in einer Manövrierstellung bewirken, in der der seitliche Überstand des Saugfußes über die Maschineneinheit zumindest an einer Seite deutlich reduziert ist, während sich an der anderen Seite der Überstand nicht oder nur äußerst geringfügig vergrößert oder sogar ebenfalls verringert. Die Bodenreinigungsmaschine kann daher in diesem Zustand durch verhältnismäßig enge Durchlässe oder Türöffnungen verfahren werden, ohne dass es erforderlich wäre, weitere Veränderungen, insbesondere ein Abnehmen des Saugfußes von der Maschineneinheit, vorzunehmen.For instance, by manually pivoting the squeegee located in its raised transport position against the restoring force it normally holds in the mid-position, the operator can effect locking in a maneuvering position in which the lateral projection of the squeegee is significantly reduced over the machine unit at least on one side. while on the other side of the supernatant is not or only slightly increased or even reduced. The floor cleaning machine can therefore be moved in this state through relatively narrow passages or door openings, without it being necessary to make further changes, in particular a removal of the squeegee of the machine unit.

Die Manövrierstellung, in der der Saugfuß verriegelbar ist, kann mit einer Endstellung des Saugfußes zusammenfallen, sie kann jedoch auch beim Verschwenken des Saugfußes erreicht werden, bevor der Saugfuß in die Endstellung gelangt.The maneuvering position, in which the squeegee can be locked, can coincide with an end position of the squeegee, but it can also be achieved during pivoting of the squeegee, before the squeegee reaches the end position.

Die Verriegelung des Saugfußes in der Manövrierstellung kann auf unterschiedliche Weisen erfolgen. Eine Möglichkeit besteht beispielsweise darin, an der Maschineneinheit einen Elektromagneten vorzusehen, der dann aktiviert wird, wenn der angehobene Saugfuß in die Manövrierstellung verschwenkt ist, so dass der Saugfuß dann durch Magnetkraft in dieser Manövrierstellung gehalten wird.The locking of the squeegee in the maneuvering can be done in different ways. One possibility is, for example, to provide on the machine unit an electromagnet, which is then activated when the raised suction cup is pivoted into the maneuvering position, so that the suction cup is then held by magnetic force in this maneuvering position.

Ein bevorzugter robuster Aufbau ergibt sich, wenn am den Saugfuß mit der Maschineneinheit verbindenden Gestänge ein Riegeleingriffsbereich vorhanden ist, mit dem ein an der Maschineneinheit vorgesehenes Riegelelement in der Manövrierstellung in lösbaren Eingriff gebracht werden kann. Dabei ist es besonders vorteilhaft, wenn das Riegelelement das Gestänge in der Eingriffstellung mit dem Riegeleingriffsbereich abstützend untergreift, um so den Saugfuß zuverlässig in seiner angehobenen Transportlage zu halten.A preferred robust construction results when a locking engagement region is provided on the linkage connecting the suction foot to the machine unit, with which a locking element provided on the machine unit can be releasably engaged in the maneuvering position. It is particularly advantageous if the locking element engages under the linkage in the engaged position with the locking engagement area, so as to keep the squeegee reliably in its raised transport position.

Der Riegeleingriffsbereich kann die Form einer Riegelaussparung haben, die zum Bewirken einer derartigen Abstützung eine längliche Durchgangsöffnung sein kann, während das Riegelelement die Form eines zumindest begrenzt drehbaren, sich im Wesentlichen senkrecht zum Boden erstreckenden Zapfens haben kann, der gegen Federkraft absenkbar ist und der einen sich seitlich erstreckenden Abstützvorsprung aufweist. Dieser Zapfen kann dann in der Manövrierstellung vom Benutzer gegen die Federkraft heruntergedrückt werden, so dass er zusammen mit seinem Abstützvorsprung durch die längliche Durchgangsöffnung hindurchtritt. Durch Verdrehen des Zapfens wird dann der Abstützvorsprung in eine Stellung gebracht, in der er den Randbereich der Durchgangsöffnung untergreift und durch die wirkende Federkraft in dieser Verriegelungsstellung gehalten wird. Dabei bewirkt er auch eine Abstützung des Gestänges und damit des Saugfußes.The latch engaging portion may be in the form of a latch recess which may be an elongated passage opening for effecting such support, while the latch member may be in the form of an at least partially rotatable, substantially perpendicularly bottomed plug which is retractable against spring force and one has laterally extending support projection. This pin can then be depressed in the maneuvering by the user against the spring force, so that it passes through the elongated passage opening together with its support projection. By turning the pin, the support projection is then brought into a position in which it engages under the edge region of the passage opening and is held in this locking position by the acting spring force. He also causes a support of the linkage and thus the squeegee.

Die dargestellte Bodenreinigungsmaschine hat eine Baueinheit 1 mit einem üblichen Chassis bzw. üblichen Rahmen, der wegen der vorhandenen Verkleidung nicht zu erkennen ist. Auf dem Chassis sind die für derartige Bodenreinigungsmaschinen üblichen, nicht dargestellten Baueinheiten angeordnet, u.a. Elektromotoren, Batterien für deren Antrieb, ein Behälter für Reinigungsflüssigkeit, ein Behälter für verbrauchte Reinigungsflüssigkeit, eine Einrichtung, um Reinigungsflüssigkeit vom Reinigungsflüssigkeitsbehälter auf den zu reinigenden Boden aufzutragen, und eine Saugpumpe zum Aufsaugen von verbrauchter Reinigungsflüssigkeit und Fördern dieser Reinigungsflüssigkeit in den Behälter für verbrauchte Reinigungsflüssigkeit. Am Chassis sind angetriebene Räder 2, 3 sowie Stützräder 4, 5 in Form von um senkrechte Achsen schwenkbaren Lenkrollen angebracht. Diese erleichtern der Bedienungsperson das Führen und Steuern der Bodenreinigungsmaschine mit Hilfe des am hinteren Ende der Baueinheit 1 angeordneten Führgriffes 11.The illustrated floor cleaning machine has a unit 1 with a conventional chassis or conventional frame, which is not recognizable because of the existing panel. On the chassis, the usual for such floor cleaning machines, not shown assemblies are arranged, including electric motors, batteries for their drive, a container for cleaning fluid, a container for spent cleaning liquid, a means to apply cleaning liquid from the cleaning liquid container to the floor to be cleaned, and a Suction pump for absorbing used cleaning liquid and conveying this cleaning liquid into the container for used cleaning liquid. On the chassis driven wheels 2, 3 and support wheels 4, 5 are mounted in the form of pivotable about vertical axes castors. These facilitate the operator to guide and control the floor cleaning machine using the arranged at the rear end of the unit 1 guide handle 11th

Ferner ist in üblicher Weise am Chassis ein Reinigungsaggregat 6 angeordnet, das schematisch dargestellt ist und zwei angedeutete, um senkrechte Achsen drehend antreibbare Reinigungsbürsten 7, 8 aufweist. Der Antrieb der Reinigungsbürsten erfolgt durch ihnen zugeordnete Elektromotoren 9, 10. Das Reinigungsaggregat steht in bekannter Weise an einer Seite der Maschineneinheit etwas vor, um auf diese Weise die Reinigung sehr nahe an Wänden zu ermöglichen.Further, a cleaning unit 6 is arranged in a conventional manner on the chassis, which is shown schematically and two indicated, to vertical axes rotationally driven cleaning brushes 7, 8 has. The cleaning brushes are driven by their associated electric motors 9, 10. The cleaning unit is in a known manner on one side of the machine unit something in order to allow in this way cleaning very close to walls.

Im hinteren Bereich des Chassis ist ferner an diesem ein bekannter und üblicher Saugfuß 12 angelenkt, der zwischen einer abgesenkten Sauglage (Fig. 1), in der er in Berührung mit dem Boden steht und verbrauchte Reinigungsflüssigkeit aufsaugt, und einer angehobenen Transportlage (Fig. 2) verlagerbar ist. Einrichtungen für das Anheben und Absenken des Saugfußes 12 sind allgemein bekannt und zur Vereinfachung der Darstellungen nicht gezeigt. Im dargestellten Ausführungsbeispiel ist der Saugfuß 12 mittels einer an ihm vorgesehenen, mittig auf seiner Oberseite befestigten Halteplatte 13 und über ein Trapezgestänge 14 mit horizontalen Schwenkachsen an einem sich senkrecht zum zu reinigenden Boden erstreckenden Zapfen 15 schwenkbar angeordnet. Dieser Zapfen ist fest am Chassis angebracht und bildet eine Achse, um die das Gestänge 14 und damit der Saugfuß 12 schwenken kann.In the rear area of the chassis, a known and conventional suction foot 12 is further articulated thereon, which between a lowered suction layer (FIG. 1), in which it is in contact with the floor and absorbs used cleaning liquid, and a raised transport layer (FIG ) is displaceable. Means for raising and lowering the squeegee 12 are well known and not shown for ease of illustration. In the illustrated embodiment, the squeegee 12 is pivotally mounted by means of a provided on it, centrally mounted on its top plate 13 and a trapezoidal linkage 14 with horizontal pivot axes on a perpendicular to the floor to be cleaned extending pin 15. This pin is fixedly mounted on the chassis and forms an axis about which the linkage 14 and thus the squeegee 12 can pivot.

Die Verschwenkbarkeit des Saugfußes 12 in seiner abgesenkten Sauglage führt dazu, dass der Saugfuß beim Kurvenfahren in üblicher Weise seitlich ausschwenkt, um den vorher mittels des Reinigungsaggregats gereinigten Boden zu überfahren und von diesem die verbrauchte Reinigungsflüssigkeit aufzunehmen. Bei Geradeausfahrt richtet sich der Saugfuß selbsttätig so aus, dass die Längsachse des Gestänges 14 in einer Ebene parallel zur Längsmittelebene der Maschineneinheit 1 verläuft. Es sei erwähnt, dass der Zapfen 15 etwas außermittig am Chassis angeordnet ist, so dass, wie in Fig. 3 zu erkennen ist, der seitliche Überstand des sich in seiner Mittelstellung befindenden Saugfußes 12 über die Maschineneinheit 1 auf der Seite des Überstandes des Reinigungsaggregats 6 etwas größer ist als auf der gegenüberliegenden Seite. Dieser Unterschied im Überstand dient dazu sicherzustellen, dass der gesamte vom Reinigungsaggregat 6 bearbeitete Bodenbereich vom Saugfuß 12 überstrichen wird.The pivotability of the squeegee 12 in its lowered suction position causes the squeegee swings laterally when cornering in the usual way to run over the previously cleaned by means of the cleaning unit soil and absorb the spent cleaning fluid from this. When driving straight ahead, the squeegee automatically aligns itself so that the longitudinal axis of the linkage 14 extends in a plane parallel to the longitudinal center plane of the machine unit 1. It should be noted that the pin 15 is arranged slightly eccentrically on the chassis, so that, as can be seen in Fig. 3, the lateral Supernatant of the located in its center position squeegee 12 on the machine unit 1 on the side of the supernatant of the cleaning unit 6 is slightly larger than on the opposite side. This difference in the supernatant serves to ensure that the entire floor area processed by the cleaning unit 6 is swept by the suction foot 12.

Wenn die dargestellte Bodenreinigungsmaschine ohne Reinigungsfunktion verfahren werden soll, bewirkt die Bedienungsperson das Anheben des Saugfußes 12 in die Transportlage (Fig. 2). In dieser wirkt üblicherweise durch die nicht dargestellte Anhebeeinrichtung auf das den Saugfuß 12 mit dem Chassis verbindende Gestänge 14 eine Rückstellkraft, die den Saugfuß in der Mittelstellung gemäß Fig. 3 hält, wobei der Saugfuß gegen diese Rückstellkraft verschwenkt werden kann. Diese von der Anhebeeinrichtung ausgeübte Rückstellkraft ist in der abgesenkten Sauglage (Fig. 1) demgegenüber deutlich reduziert, damit der Saugfuß beim Kurvenfahren seitlich ausschwenken und ggfs. bis in die in beiden Ausschwenkrichtungen vorhandenen Endlagen ausschwenken kann, die üblicherweise durch Anschläge bestimmt sind.When the illustrated floor cleaning machine is to be moved without a cleaning function, the operator causes the suction foot 12 to be lifted into the transport position (FIG. 2). In this usually acts by the lifting device, not shown on the connecting the Saugfuß 12 to the chassis linkage 14, a restoring force that holds the squeegee in the middle position shown in FIG. 3, wherein the squeegee can be pivoted against this restoring force. This restoring force exerted by the lifting device is in contrast significantly reduced in the lowered suction layer (FIG. 1), so that the squeegee can swivel laterally when cornering and, if necessary, swing out into the end positions present in both swiveling directions, which are usually determined by stops.

Der vorstehend beschriebene Grundaufbau einer Bodenreinigungsmaschine und deren Arbeitsweise ist sowohl für handgeführte Bodenreinigungsmaschinen der dargestellten Art als auch für Aufsitzmaschinen üblich, so dass die verhältnismäßig kurzen Erläuterungen, auch unter Hinweis auf nicht dargestellte Baueinheiten, zum Verständnis ausreichen.The above-described basic structure of a floor cleaning machine and its operation is common both for hand-held floor cleaning machines of the type shown as well as ride-on machines, so that the relatively short explanations, even with reference to units not shown sufficient for understanding.

Wie insbesondere in Fig. 3 zu erkennen ist, stehen beim Verfahren der Bodenreinigungsmaschine mit in angehobener Transportlage befindlichem Saugfuß 12 die Endbereiche des Saugfußes an gegenüberliegenden Seiten der Maschineneinheit 1 erheblich vor, und darüber hinaus ist ein gewisser seitlicher Überstand des Reinigungsaggregats 6 an einer Seite der Maschineneinheit 1 vorhanden. Wenn die Bedienungsperson in diesem Zustand durch eine relativ enge Türöffnung o.ä. fahren möchte, um die Bodenreinigungsmaschine von einem zu reinigenden Bereich in einen anderen zu bewegen, so gelingt es ihr im Allgemeinen durch entsprechend schräges Anfahren der Türöffnung, den überstehenden Bereich des Reinigungsaggregats 6 durch diese hindurch zu manövrieren, um dann in Geradeausfahrt das Verfahren der Bodenreinigungsmaschine fortzusetzen. Nicht mehr möglich ist jedoch dabei das Durchfahren der engeren Türöffnung, wenn deren Breite deutlich geringer als die sich durch den beidseitigen Überstand des Saugfußes ergebende Breite ist. In solchen Fällen ist es üblich, dass die Bedienungsperson den Saugfuß abmontiert und dann die Bodenreinigungsmaschine durch die Türöffnung hindurchführt, um danach den Saugfuß wieder zu montieren. Dies ist offensichtlich umständlich und zeitraubend.As can be seen in particular in FIG. 3, when the floor cleaning machine is in operation with the suction foot 12 in the raised transport position, the end areas of the suction foot are substantially present on opposite sides of the machine unit 1, and, moreover, there is a certain lateral projection of the cleaning unit 6 on one side of the machine unit 1 available. If the operator in this state by a relatively narrow door opening or similar. would like to drive to move the floor cleaning machine from one area to be cleaned in another, so she manages generally by appropriately oblique start the door opening to maneuver the protruding portion of the cleaning unit 6 therethrough, then in straight travel the method of floor cleaning machine continue. However, it is no longer possible to drive through the narrower door opening if its width is significantly less than the width resulting from the two-sided projection of the suction foot. In such cases, it is common for the operator to disassemble the squeegee and then pass the floor cleaning machine through the door opening to then reassemble the squeegee. This is obviously cumbersome and time consuming.

Bei der dargestellten Bodenreinigungsmaschine kann die Bedienungsperson den in der angehobenen Transportlage befindlichen Saugfuß manuell und gegen die ggfs. wirkende Rückstellkraft in Richtung weg vom seitlichen Überstand des Reinigungsaggregats 6 in eine Manövrierstellung (Fig. 4 und 5) verschwenken. Wie insbesondere Fig. 4 zeigt, reduziert sich dadurch der Überstand des Saugfußes 12 auf der Seite des Überstandes des Reinigungsaggregats 6 erheblich. Durch entsprechende Anbindung des Saugfußes kann auch dessen Überstand auch auf der gegenüberliegenden Seite verringert werden. In dieser Manövrierstellung, die die Endstellung des Saugfußes in dieser Verschwenkrichtung sein, die jedoch auch vor der Endstellung liegen kann, kann die Bedienungsperson den Saugfuß verriegeln. Hierzu ist am Gestänge 14 starr ein in etwa L-förmiger Riegelarm 16 befestigt, der im Endbereich seines seitlich abstehenden Schenkels eine schlüssellochförmige Öffnung 17 (Fig. 7) aufweist. Ferner ist an einer am Chassis befestigten Tragplatte 21 ein Riegelzapfen 18 gehaltert. Dieser Riegelzapfen erstreckt sich mit seiner Längsachse im Wesentlichen senkrecht zum zu reinigenden Boden und durch die Tragplatte 21, so dass sich sein unteres Ende, an dem ein seitlich vorspringender Abstützvorsprung 19 ausgebildet ist, unterhalb der Tragplatte befindet. Der Riegelzapfen 18, der aus zwei fest miteinander verbundenen Teilen zusammengesetzt ist, um ihn vor der Herstellung der Verbindung durch die Tragplatte 21 hindurchführen zu können, hat oberhalb der Tragplatte eine Ringschulter, an der sich eine Druckfeder 20 abstützt, die auch auf der Tragplatte aufliegt. Auf diese Weise wird der Riegelzapfen 18 normalerweise in einer angehobenen Stellung gehalten, die durch eine nicht gezeigte Ringschulter am unterhalb der Tragplatte 21 befindlichen Abschnitt des Riegelzapfenes 18 festgelegt wird.In the illustrated floor cleaning machine, the operator can pivot the suction in the raised transport position manually and against the possibly. Actuating restoring force in the direction away from the side projection of the cleaning unit 6 in a maneuvering position (Figs 4 and 5). As shown particularly in FIG. 4, the supernatant of the suction foot 12 on the supernatant side of the cleaning unit 6 is thereby considerably reduced. By appropriate connection of the squeegee and its supernatant can also be reduced on the opposite side. In this maneuvering position, which may be the end position of the squeegee in this pivoting direction, but which may also be before the end position, the operator can lock the squeegee. For this purpose, a roughly L-shaped locking arm 16 is fixed to the linkage 14, which has a keyhole-shaped opening 17 (FIG. 7) in the end region of its laterally projecting leg. Further, a locking pin 18 is supported on a support plate 21 attached to the chassis. This locking pin extends with its longitudinal axis substantially perpendicular to the floor to be cleaned and by the support plate 21, so that its lower end, on which a laterally projecting support projection 19 is formed, located below the support plate. The locking pin 18, which is composed of two firmly interconnected parts in order to pass it through the support plate 21 before the connection can be made, above the support plate has an annular shoulder on which a compression spring 20 is supported, which also rests on the support plate , In this way, the locking pin 18 is normally held in a raised position, which is determined by an annular shoulder, not shown, located on the underside of the support plate 21 portion of the locking pin 18.

Um den Saugfuß zu verriegeln, verschwenkt die Bedienungsperson diesen in seiner angehobenen Sauglage in die Manövrierstellung. In dieser richtetet sie den Riegelzapfen durch Ergreifen an seinem oberen Griffbereich und Verdrehen um seine Längsachse so aus, dass der Abstützvorsprung 19 mit dem schmaleren Teil der schlüssellochförmigen Öffnung 17 fluchtet, und drückt dann den Riegelzapfen gegen die Kraft der Feder 20 herunter, um den Abstützvorsprung 19 durch die Riegelaussparung hindurchtreten zu lassen. Durch Verdrehen des Riegelzapfenes 18 um seine Längsachse wird der Abstützvorsprung 19 so unter den Randbereich der Durchgangsöffnung 17 verlagert, dass die Aufwärtsbewegung des Riegelzapfens 18 begrenzt und auf diese Weise der Saugfuß 12 in der Manövrierstellung verriegelt wird. Dabei bewirkt der Abstützvorsprung 19 auch eine zusätzliche Abstützung des Saugfußes gegen eine Absenkbewegung.To lock the squeegee, the operator pivots this in his raised suction position in the maneuvering position. In this it aligns the locking pin by gripping at its upper handle portion and twisting about its longitudinal axis so that the support projection 19 is aligned with the narrower part of the keyhole-shaped opening 17, and then pushes down the locking pin against the force of the spring 20 to the support projection 19 to pass through the latch recess. By rotating the locking pin 18 about its longitudinal axis of the support projection 19 is displaced below the edge region of the through hole 17 so that the upward movement of the locking pin 18 is limited and locked in this way, the suction 12 in the maneuvering. The support projection 19 also causes an additional support of the suction against a lowering movement.

Nach dem Durchfahren der schmalen Türöffnung entriegelt die Bedienungsperson den Saugfuß 12 dadurch, dass sie durch Drehung des Riegelzapfens 18 den Abstützvorsprung 19 wieder in fluchtende Ausrichtung mit der Längserstreckung der schlüssellochförmigen Durchgangsöffnung 17 bringt und den Riegelzapfen in dieser Stellung freigibt. Der Riegelzapfen wird dann infolge der Kraft der Feder 20 angehoben und aus der Durchgangsöffnung in die Lage gemäß Fig. 7 bewegt. Nunmehr kann der in angehobener Transportlage befindliche Saugfuß in die Mittelstellung zurückschwenken.After passing through the narrow door opening, the operator unlocks the squeegee 12 in that by rotation of the locking pin 18, the support projection 19 again in alignment with the longitudinal extent of the keyhole-shaped Through opening 17 brings and releases the locking pin in this position. The locking pin is then lifted due to the force of the spring 20 and moved from the passage opening in the position shown in FIG. 7. Now, the squeegee located in the raised transport position can swing back into the middle position.
