Description

Die Erfindung betrifft eine Kehrmaschine mit einem Gehäuse, einem Kehrgutbehälter und einer vom Gehäuse überdeckten Kehrwalze, die an einer Höhenverstelleinrichtung um eine Drehachse drehbar gelagert ist, wobei die Höhenverstelleinrichtung mittels einer Verstellmechanik um eine parallel zur Drehachse ausgerichtete Schwenkachse verschwenkbar ist.The invention relates to a sweeper with a housing, a hopper and a sweeping roller covered by the housing and connected to a height adjustment device is mounted rotatably about a rotation axis, wherein the height adjustment by means of an adjustment mechanism about a parallel to the axis of rotation aligned pivot axis is pivotable.

Mittels derartiger Kehrmaschinen kann eine Bodenfläche, beispielsweise ein Parkplatz oder eine Hallenfläche, gekehrt werden, wobei das Kehrgut mittels der drehbaren Kehrwalze in den Kehrgutbehälter überführt wird. Die Kehrwalze weist eine Vielzahl von Borsten auf, und bei häufigem Einsatz der Kehrmaschine auf rauhen Bodenflächen kann es zu einer Abnutzung der Borsten kommen, so daß die Lage der Kehrwalze zu der zu reinigenden Bodenfläche nachgestellt werden muß. Hierzu wird in der EP 0 157 925 B1 eine Höhenverstelleinrichtung vorgeschlagen, an der die Kehrwalze drehbar gelagert ist und die mittels zweier Stellschrauben in ihrer Lage bezüglich der Bodenfläche eingestellt werden kann. Eine ähnlich ausgestaltete Höhenverstelleinrichtung, deren Lage ebenfalls mittels einer Stellschraube eingestellt werden kann, ist aus der DE 87 17 834 U1 bekannt. Der Einsatz von Stellschrauben erfordert in den meisten Fällen die Zuhilfenahme von zusätzlichem Werkzeug, um die Kehrwalze in ihrer Lage verändern zu können, da die Stellschrauben meist fest sitzen und deshalb von Hand nicht ohne weiteres gelöst werden können. Außerdem sind zu einer Lageänderung der Kehrwalze meist mehrere Umdrehungen der Stellschrauben erforderlich, dies führt zu einer umständlichen Handhabung. Nachteilig ist darüber hinaus, daß der Benutzer anhand der Stellschrauben die tatsächliche Stellung der Kehrwalze nur schlecht erkennen kann, so daß eine zusätzliche Anzeigevorrichtung erforderlich ist, um die Lage der Kehrwalze für den Benutzer erkennbar zu machen.By means of such sweeping machines, a floor surface, for example a Parking space or a hall area, to be swept, with the sweepings by means of the rotatable sweeping roller is transferred to the hopper. The broom has a variety of bristles, and with frequent use of the sweeper on rough surfaces, the bristles may wear out come, so that the position of the sweeping roller to the surface to be cleaned must be readjusted. For this purpose, EP 0 157 925 B1 discloses a height adjustment device proposed, on which the sweeping roller is rotatably mounted and adjusted by means of two screws in their position with respect to the bottom surface can be. A similarly configured height adjustment device, whose position can also be adjusted by means of a set screw is known from DE 87 17 834 U1. The use of set screws requires in In most cases, the use of additional tools to the To be able to change broom in their position, as the screws usually fixed sit and therefore can not be solved by hand easily. In addition to a change in position of the sweeping roller are usually several Turning the screws required, this leads to a cumbersome handling. Another disadvantage is that the user using the set screws the actual position of the sweeping roller only can be poorly recognized, so that an additional display device is necessary to make the position of the broom recognizable to the user do.

Aus der DE 94 03 681 U1 ist eine Kehrmaschine der eingangs genannten Art bekannt, bei der die Höhenverstelleinrichtung mit einer konstruktiv aufwendigen Verstellmechanik zusammenwirkt, die eine aus dem Gehäuse der Kehrmaschine herausragende Drehscheibe mit Griffmulden aufweist, an der drehfest ein Exzenter gehalten ist, der wiederum mit einem zweiarmigen Hebel der Höhenverstelleinrichtung zusammenwirkt. Hierzu weist der Exzenter außenseitig mehrere Rastvertiefungen auf, in die eine Rastnase des zweiarmigen Hebels einrasten kann. Um sicherzustellen, daß die Höhenverstelleinrichtung eine von der Drehscheibe vorgegebene Stellung beibehält, ist der zweiarmige Hebel mittels einer Feder in Richtung der Rastvertiefungen des Exzenters elastisch vorgespannt. Zur Höhenverstellung muß der Benutzer zum Verdrehen der Drehscheibe die elastische Vorspannkraft überwinden, wobei ungünstige Hebelverhältnisse vorliegen, so daß zur Höhenverstellung der Kehrwalze ein nicht unerheblicher Kraftaufwand erforderlich sein kann.From DE 94 03 681 U1 is a sweeper of the type mentioned known, in which the height adjustment device with a structurally complex Adjusting mechanism cooperates, one from the housing of the sweeper outstanding turntable with recessed grips, on the non-rotatable an eccentric is held, in turn, with a two-armed lever height adjustment interacts. For this purpose, the eccentric on the outside a plurality of locking recesses into which a detent of the two-armed lever can engage. To ensure that the height adjustment of one of the turntable maintains predetermined position is the two-armed lever by means of a spring in the direction of the locking recesses of the eccentric elastic biased. To adjust the height, the user must to twist the Turntable overcome the elastic preload, with unfavorable leverage present, so that the height adjustment of the sweeping roller not one Insignificant effort may be required.

Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Kehrmaschine derart weiterzubilden, daß die Lage der Kehrwalze mit verhältnismäßig geringem Kraftaufwand verändert werden kann, wobei die Kehrmaschine einen konstruktiv einfachen Aufbau aufweist. Object of the present invention is a generic sweeper in such a way that the position of the sweeping roller with relatively little effort can be changed, the sweeper a structurally simple construction.

Diese Aufgabe wird bei einer Kehrmaschine der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Verstellmechanik einen um die Schwenkkachse verschwenkbaren Schwenkarm aufweist, der aus dem Gehäuse herausragt und in unterschiedlichen Schwenkstellungen lösbar arretierbar ist.This object is according to the invention in a sweeper of the type mentioned solved in that the adjustment mechanism to a pivot axis comprising pivotable pivot arm which protrudes from the housing and is releasably lockable in different pivot positions.

Bei der erfindungsgemäßen Kehrmaschine ist es zur Änderung der Lage der Kehrwalze relativ zu der zu reinigenden Bodenfläche lediglich erforderlich, den Schwenkarm um die Schwenkachse zu verschwenken und in der gewünschten Schwenkstellung zu arretieren, vorzugsweise mit dem Gehäuse zu verrasten. Hierbei ergeben sich sehr günstige Hebelverhältnisse, so daß eine Lageänderung der Kehrwalze mit einem geringen Kraftaufwand verbunden ist.In the sweeper according to the invention it is to change the position of the Sweeping roller relative to the surface to be cleaned only required, the Swivel arm to pivot about the pivot axis and in the desired Locking pivot position, preferably to lock with the housing. This results in very favorable leverage, so that a change in position the broom is associated with a small amount of force.

Von Vorteil ist es, wenn an dem aus dem Gehäuse herausragenden Endbereich des Schwenkarms ein Handgriff angeordnet ist, der zwischen einer Raststellung, in der der Schwenkarm arretiert ist, und einer Freigabestellung, in der der Schwenkarm verschwenkbar ist, hin und her bewegbar am Schwenkarm gehalten ist. Soll die Lage der Kehrwalze verändert werden, so kann hierzu der Handgriff aus seiner Raststellung in seine Freigabestellung bewegt werden und anschließend kann der Schwenkarm in die gewünschte Schwenkstellung verschwenkt und dann wieder mittels des Handgriffs arretiert werden, vorzugsweise mit dem Gehäuse verrastet werden.It is advantageous if at the protruding end of the housing from the housing of the swivel arm, a handle is arranged between a detent position, in which the swivel arm is locked, and a release position, in the the swivel arm is pivotable, movable back and forth on the swivel arm is held. If the position of the sweeping roller to be changed, so can this Handle to be moved from its rest position to its release position and then the swivel arm can be pivoted into the desired pivoting position and then locked again by means of the handle, preferably be locked with the housing.

Der Übergang zwischen der Raststellung und der Freigabestellung des Handgriffs kann beispielsweise durch Drehung des Handgriffs erfolgen. Eine konstruktiv besonders einfache Ausgestaltung der Kehrmaschine kann dadurch erzielt werden, daß der Handgriff in Längsrichtung des Schwenkarms hin und her verschiebbar ist. Zum Lösen des Handgriffs aus seiner Raststellung kann beispielsweise vorgesehen sein, daß der Handgriff vom Benutzer in Richtung der Schwenkachse gedrückt wird. Eine besonders einfache Handhabung kann dadurch erzielt werden, daß der Übergang des Handgriffs von seiner Raststellung in seine Freigabestellung durch Abheben des Handgriffs vom Gehäuse erfolgt. Der Benutzer muß bei einer derartigen Ausführungsform den Handgriff lediglich etwas nach außen ziehen und kann dann den Schwenkarm in eine neue Schwenkstellung überführen.The transition between the detent position and the release position of the handle can be done for example by rotation of the handle. A constructive Particularly simple embodiment of the sweeper can thereby be achieved, that the handle in the longitudinal direction of the pivot arm out and is displaceable ago. To release the handle from its rest position can For example, be provided that the handle from the user in the direction the pivot axis is pressed. A particularly easy handling can be achieved in that the transition of the handle from its rest position in its release position by lifting the handle from the housing he follows. The user must in such an embodiment, the handle just pull something outward and then the swing arm in a transfer new pivot position.

Von Vorteil ist es, wenn der Handgriff in seine Raststellung elastisch vorgespannt ist, denn dadurch wird eine unbeabsichtigte Verstellung des Schwenkarms zuverlässig vermieden.It is advantageous if the handle is elastically biased in its rest position is, because this is an unintentional adjustment of the swing arm reliably avoided.

Vorzugsweise sind am Gehäuse Rastelemente, beispielsweise Rastnoppen oder Rastvertiefungen, angeordnet, die mit korrespondierenden Rastelementen des Handgriffs zusammenwirken. Hierbei ist es günstig, wenn die Rastelemente außenseitig am Gehäuse angeordnet sind und mit den korrespondierenden Rastelementen des Handgriffs in Eingriff bringbar sind. Beispielsweise kann vorgesehen sein, daß der Handgriff auf seiner dem Gehäuse zugewandten Unterseite Rastaufnahmen aufweist, in die außenseitig am Gehäuse angeordnete Rastnoppen eingreifen.Preferably, the housing locking elements, such as locking knobs or Locking depressions, arranged, with the corresponding locking elements of the Handle together. It is advantageous if the locking elements are arranged on the outside of the housing and with the corresponding Locking elements of the handle can be brought into engagement. For example, can be provided that the handle facing the housing on its Has underside latching receptacles, arranged in the outside of the housing Engage locking knobs.

Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Kehrmaschine weist der Handgriff eine den aus dem Gehäuse herausragenden Endbereich des Schwenkarms umgebende Hülse auf, die mittels eines Federelements in Richtung der Rastelemente des Gehäuses elastisch vorgespannt ist. Die Hülse ist in Längsrichtung des Schwenkarms verschiebbar an diesem gehalten und kann entgegen der Wirkung des Federelements aus einer Raststellung, in der sie an den Rastelementen des Gehäuses anliegt, in eine Freigabestellung, in der sie im Abstand zu den am Gehäuse angeordneten Rastelementen positioniert ist, überführt werden.In a preferred embodiment of the sweeper according to the invention the handle has an end portion protruding from the housing the sleeve surrounding the pivot arm, which by means of a spring element in Direction of the locking elements of the housing is resiliently biased. The sleeve is slidably held in the longitudinal direction of the pivot arm on this and can, contrary to the action of the spring element from a detent position in the it rests against the locking elements of the housing, in a release position, in they are positioned at a distance from the latching elements arranged on the housing is to be convicted.

Die Freigabestellung des Handgriffs wird bei einer vorteilhaften Ausführungsform der Erfindung durch ein Anschlagelement vorgegeben, das an dem aus dem Gehäuse herausragenden Ende des Schwenkarms angeordnet ist. Das Anschlagelement kann hierbei einen Gegenhalter ausbilden für den Benutzer beim Betätigen des Handgriffs. Dies ist vor allem bei leichtgängigen, handgeschobenen Kehrmaschinen von Vorteil, die mit geringer Kraft verschoben werden können. Günstig ist es hierbei, wenn das Federelement zwischen dem Anschlag und der Hülse eingespannt ist.The release position of the handle is in an advantageous embodiment of the invention predetermined by a stop element, on the off the housing protruding end of the pivot arm is arranged. The Stop element can in this case form a counter-holder for the user when operating the handle. This is especially true for smooth-running, Hand-pushed sweepers of advantage with low power can be moved. It is favorable in this case if the spring element is clamped between the stop and the sleeve.

Das Federelement kann als den Schwenkarm umgebende Schraubenfeder ausgestaltet sein. Mittels der Schraubenfeder kann die Hülse mit einer Druckkraft in Richtung auf das Gehäuse der Kehrmaschine beaufschlagt werden.The spring element can be used as a coil spring surrounding the pivoting arm be designed. By means of the coil spring, the sleeve with a compressive force be acted upon in the direction of the housing of the sweeper.

Vorzugsweise umgibt die Hülse die Schraubenfeder in Umfangsrichtung. Die Hülse bildet somit einen mechanischen Schutz für die Schraubenfeder.Preferably, the sleeve surrounds the coil spring in the circumferential direction. The Sleeve thus forms a mechanical protection for the coil spring.

Bei einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Kehrmaschine weist die Höhenverstelleinrichtung zwei um die Schwenkachse verschwenkbare Tragarme auf, an denen die Kehrwalze verdrehbar gelagert ist und die über eine Querstrebe starr miteinander verbunden sind, wobei der Schwenkarm an der Querstrebe festgelegt ist. Die beiden Tragarme und die sie verbindende Querstrebe bilden in Kombination mit dem von der Querstrebe abstehenden Schwenkarm für die Kehrwalze eine gabelförmige Aufhängung aus, die vom Benutzer zur Änderung der Lage der Kehrwalze bezogen auf die Bodenfläche auf einfache Weise verschwenkt werden kann.In a particularly preferred embodiment of the invention Sweeper has the height adjustment two about the pivot axis pivotable support arms on which the sweeping roller is rotatably mounted and which are rigidly connected to each other via a cross brace, wherein the Swivel arm is fixed to the crossbar. The two support arms and they connecting cross strut in combination with that of the cross strut protruding swivel arm for the sweeping roller a fork-shaped suspension made by the user to change the position of the roller brush relative to the Floor surface can be easily pivoted.

Vorzugsweise weist die Kehrmaschine zwei Laufräder sowie zumindest ein Stützrad auf, wobei die Laufräder um eine gemeinsame Radachse verdrehbar sind und wobei die Schwenkachse der Höhenverstelleinrichtung koaxial zur Radachse ausgerichtet ist. Die Laufräder können über einen Antriebsstrang mit der Kehrwalze gekoppelt sein, so daß die Drehbewegung der Laufräder auf die Kehrwalze übertragen wird. Die Ausrichtung der Schwenkachse der Höhenverstelleinrichtung koaxial zur Radachse der Laufräder hat den Vorteil, daß bei einer Schwenkbewegung der Höhenverstelleinrichtung der Antriebsstrang zwischen den Laufrädern und der Kehrwalze nicht nachjustiert werden muß.Preferably, the sweeper has two wheels and at least one Support wheel, wherein the wheels rotatable about a common wheel axle are and wherein the pivot axis of the height adjustment coaxial with Wheel axis is aligned. The wheels can be powered by a powertrain coupled to the sweeping roller, so that the rotational movement of the wheels on the Sweeping roller is transferred. The orientation of the pivot axis of the height adjustment coaxial with the wheel axle of the wheels has the advantage that at a pivoting movement of the height adjustment of the drive train must not be readjusted between the wheels and the sweeping roller.

Besonders günstige Hebelverhältnisse und folglich ein besonders geringer Kraftaufwand zur Lageänderung der Kehrwalze können dadurch erzielt werden, daß der Schwenkarm bezogen auf die Schwenkachse in radialer Richtung von der die beiden Tragarme miteinander verbindenden Querstrebe absteht.Particularly favorable leverage ratios and consequently a particularly low Force to change the position of the sweeping roller can be achieved, that the pivot arm relative to the pivot axis in the radial direction of of the two support arms interconnecting cross strut protrudes.

Wie eingangs erwähnt, übergreift das Gehäuse die Kehrwalze. Hierbei kann eine besonders einfache Bedienung der Kehrmaschine zur Lageänderung der Kehrwalze dadurch erzielt werden, daß das Gehäuse in einem die Kehrwalze überdeckenden Bereich bezogen auf die Schwenkachse kreisbogenförmig geformt ist, denn dies hat den Vorteil, daß bei einem Verschwenken des Schwenkarms der Abstand, den der Handgriff zum Gehäuse aufweist, unverändert bleibt. As mentioned above, the housing engages over the sweeping roller. Here can a particularly simple operation of the sweeper for changing the position of Sweeping roller can be achieved in that the housing in a sweeping roller overlapping area based on the pivot axis circular arc-shaped is because this has the advantage that when pivoting the Swivel arm, the distance that has the handle to the housing, unchanged remains.

In the dirt container 14 can by means of a covered by a housing 16 sweeping roller 18 debris be transferred, such as dirt, leaves and stones. From the frame 12 is inclined to the vertical upwards a push bar 20 from which is detachably connectable to the frame 12, and in its rear Area are on the frame 12 two wheels 22, 24 mounted around a common Wheel axle 26 are rotatable. The wheels 22, 24 are over a known per se and therefore to achieve a better overview in the drawing, not shown drive train with the between the two Impellers 22, 24 arranged sweeping roller 18 in rotary connection such, that a rotational movement of the wheels 22, 24 transmitted to the sweeping roller 18 becomes.

Die Kehrwalze 18 weist eine Vielzahl von Kehrborsten 28 auf, mit deren Hilfe eine zu reinigende Bodenfläche 30 gekehrt werden kann. Insbesondere bei der Reinigung von rauhen Bodenflächen 30 ist eine Abnutzung der Kehrborsten 28 unvermeidlich. Bei der erfindungsgemäßen Kehrmaschine 10 ist daher die Kehrwalze 18 an einer in Figur 2 schematisch dargestellten Höhenverstelleinrichtung 32 drehbar gelagert, die an jeder Stirnseite der zylinderförmigen Kehrwalze 18 einen Tragarm 34 aufweist, der um eine koaxial zur Radachse 26 ausgerichtete Schwenkachse 36 verschwenkbar am Rahmen 12 gehalten ist und an einem freien Endbereich eines ersten Hebelarms 38 die Kehrwalze 18 um eine Drehachse 40 drehbar lagert, während das freie Ende eines zweiten Hebelarms 42 des Tragarms 34 über eine parallel zur Schwenkachse 36 ausgerichtete Querstrebe 44 mit dem an der anderen Stirnseite der Kehrwalze 18 angeordneten Tragarm starr verbunden ist. Von der Querstrebe 44 steht mittig ein bezogen auf die Schwenkachse 36 radial ausgerichteter Schwenkarm 46 ab, der starr mit der Querstrebe 44 verbunden ist und eine längliche Durchgangsöffnung 48 des Gehäuses 16 durchgreift und mit einem freien Endbereich 50 über das Gehäuse 16 übersteht.The sweeping roller 18 has a plurality of sweeping bristles 28, with their help a floor surface 30 to be cleaned can be swept. Especially at the Cleaning of rough floor surfaces 30 is a wear of sweeping bristles 28th inevitable. In the sweeping machine 10 according to the invention is therefore the Sweeping roller 18 on a height adjustment device shown schematically in Figure 2 32 rotatably mounted, which on each end face of the cylindrical Sweeping roller 18 has a support arm 34 which is a coaxial with the wheel axle 26th aligned pivot axis 36 is pivotally supported on the frame 12 and at a free end portion of a first lever arm 38, the sweeping roller 18th rotatably supported about a rotation axis 40, while the free end of a second Lever arm 42 of the support arm 34 via a parallel to the pivot axis 36 aligned Cross strut 44 with the other end face of the sweeping roller 18th arranged support arm is rigidly connected. From the cross strut 44 is centered a with respect to the pivot axis 36 radially aligned pivot arm 46th from which is rigidly connected to the crossbar 44 and an elongated passage opening 48 of the housing 16 passes through and with a free end portion 50 projects beyond the housing 16.

Auf seinem freien Ende trägt der Schwenkarm 46 ein mittels einer Verbindungsschraube lösbar mit diesem verbundenes querstehendes Anschlagelement 52. Der freie Endbereich 50 des Schwenkarms 46 ist von einem Handgriff 54 umgeben, der in Längsrichtung des Schwenkarms 46 verschiebbar am freien Endbereich 50 gehalten ist.On its free end, the pivot arm 46 carries by means of a connecting screw detachable connected with this transverse standing Stop element 52. The free end portion 50 of the pivot arm 46 is of a handle 54 which in the longitudinal direction of the pivot arm 46th slidably held at the free end portion 50.

Der Handgriff 54 weist eine Hülse 56 auf, die den freien Endbereich 50 des Schwenkarms 46 in Umfangsrichtung umgibt und in Höhe des Anschlagelements 52 einstückig mit einem querstehenden Griffteil 58 verbunden ist. Das Griffteil 58 ist wannenförmig ausgestaltet und nimmt das querstehende Anschlagelement 52 auf. Der Handgriff 54 ist somit insgesamt T-förmig ausgestaltet. In ihrem dem Griffteil 58 zugewandten Endbereich weist die Hülse 56 eine Aufnahme 60 auf, in der eine schraubenförmige Druckfeder 62 angeordnet ist, die den außenstehenden Endabschnitt des freien Endbereichs 50 des Schwenkarms 46 in Umfangsrichtung umgibt und zwischen dem Anschlagelement 52 und einer Bodenwand der Aufnahme 60 eingespannt ist. Mittels der Druckfeder 62 wird die Hülse 56 elastisch in Richtung des Gehäuses 16 vorgespannt.The handle 54 has a sleeve 56 which defines the free end portion 50 of FIG Swing arm 46 circumferentially surrounds and in the amount of the stop element 52 is integrally connected to a transverse handle portion 58. The Handle 58 is designed trough-shaped and takes the querstehende Stop element 52. The handle 54 is thus a total of T-shaped designed. In its handle portion 58 facing end region, the Sleeve 56 a receptacle 60 in which a helical compression spring 62nd is arranged, which is the outer end portion of the free end portion 50 of the pivot arm 46 circumferentially surrounds and between the Stop element 52 and a bottom wall of the receptacle 60 is clamped. By means of the compression spring 62, the sleeve 56 is elastically in the direction of the housing 16 biased.

Das Gehäuse 16 ist im Bereich der Durchgangsöffnung 48 bezogen auf die Schwenkachse 36 kreisbogenförmig geformt und weist zu beiden Seiten der länglichen Durchgangsöffnung 48 Rastelemente in Form von Rastnoppen 64 auf, die mit korrespondierenden Rastelementen in Form von Rastaufnahmen 66 zusammenwirken, welche in die dem Gehäuse 16 zugewandte Stirnseite der Hülse 56 eingeformt sind.The housing 16 is in the region of the passage opening 48 with respect to the Swivel axis 36 arc-shaped and has on both sides of the elongate passage opening 48 locking elements in the form of locking knobs 64th on, with the corresponding locking elements in the form of locking receptacles 66 cooperate, which in the housing 16 facing end face the sleeve 56 are formed.
