Abstract

The invention relates to a mobile floor-cleaning appliance having a housing in which a cleaning tool is mounted, and having a handle holder which is mounted on the housing and is adapted to be connected to a handle in order to guide the appliance along a floor surface which is to be cleaned. In order to develop the mobile floor-cleaning appliance such that the handle holder can be reliably arrested in a rest position and can easily be transferred from the rest position into an operating position, it is proposed according to the invention that the handle holder is adapted to be pivoted about two pivot axes oriented obliquely or perpendicularly in relation to one another and is adapted to be arrested in a rest position, at least one arresting element being associated with each of the two pivot axes, for arresting the handle holder, wherein it is possible to eliminate the arresting action on the handle holder in relation to the two pivot axes by virtue of the handle holder being pivoted as desired out of the rest position about one of the two pivot axes.

Description

Fahrbares Bodenreinigungsgerät Mobile floor cleaning device
Die Erfindung betrifft ein fahrbares Bodenreinigungsgerät mit einem Gehäuse, in dem ein Reinigungswerkzeug gehalten ist, und mit einem am Gehäuse gelagerten Stielhalter, der mit einem Stiel zum Führen des Bodenreinigungsgeräts entlang einer zu reinigenden Bodenfläche verbindbar ist.The invention relates to a mobile floor cleaning device with a housing in which a cleaning tool is held, and with a handle mounted on the housing handle, which is connectable with a handle for guiding the floor cleaning device along a floor surface to be cleaned.
Mittels derartiger Bodenreinigungsgeräte kann eine Bodenfläche auf einfache Weise gereinigt werden, indem das Gerät an der Bodenfläche entlang geführt wird. Zum Führen des Geräts entlang der Bodenfläche weist dieses einen Stiel auf, der über einen Stielhalter am Gehäuse des Bodenreinigungsgeräts gelagert ist. Das Bodenreinigungsgerät kann beispielsweise als fahrbares Kehrgerät ausgestaltet sein, wobei in dem Gehäuse eine drehangetriebene Bürstenwalze gelagert ist und ein Schmutzsammelbehälter der Büstenwalze benachbart angeordnet ist, so daß die vorzugsweise mittels eines Elektromotors angetriebene Bürstenwalze Schmutz von der Bodenfläche aufnehmen kann, der in den Schmutzsammelbehälter überführt wird. Derartige Kehrgeräte sind beispielsweise aus der DE 299 13 845 Ul bekannt.By means of such floor cleaning devices, a floor surface can be easily cleaned by the device is guided along the bottom surface. To guide the device along the bottom surface of this has a handle which is mounted on a handle holder on the housing of the floor cleaning device. The floor cleaning device can be configured, for example, as a mobile sweeping device, wherein a rotationally driven brush roller is mounted in the housing and a dirt collecting container of the brush roller is disposed adjacent, so that the preferably powered by an electric motor brush roller can pick up dirt from the bottom surface, which is transferred to the dirt collecting , Such sweepers are known for example from DE 299 13 845 Ul.
Insbesondere zur Lagerung des Bodenreinigungsgeräts ist es von Vorteil, wenn der Stielhalter und der mit diesem verbundene Stiel in einer Ruhelage mit vorgegebener Ausrichtung, insbesondere mit vertikaler Ausrichtung, arretiert werden kann.In particular for the storage of the floor cleaning appliance, it is advantageous if the handle holder and the handle connected thereto can be locked in a rest position with a predetermined orientation, in particular with a vertical orientation.
Zur Lagerung eines Stielhalters am Gehäuse eines Reinigungsgeräts wird in der DE 299 03 196 Ul ein Kardangelenk vorgeschlagen, mit dessen Hilfe der Stielhalter um zwei senkrecht zueinander ausgerichtete Schwenkachsen verschwenkt werden kann. Außerdem kann der Stielhalter in einer Ruhelage mit vertikaler Ausrichtung arretiert werden. Er weist hierzu an seinem dem Gehäuse zugewandten Ende einen Rastvorsprung auf, der in eine korrespondierende Rastaufnahme des Gehäuses eingeführt werden kann. Sowohl zum Lösen als auch zum Herstellen der Arretierung ist eine nicht unerhebliche Krafteinwirkung erforderlich.For storage of a handle holder on the housing of a cleaning device, a universal joint is proposed in DE 299 03 196 Ul Ul, with the help of the Handle holder can be pivoted about two pivot axes aligned perpendicular to each other. In addition, the handle holder can be locked in a rest position with vertical alignment. For this purpose, it has at its end facing the housing a latching projection which can be inserted into a corresponding latching receptacle of the housing. Both for releasing and for producing the locking a considerable force is required.
Aufgabe der vorliegenden Erfindung ist es, ein fahrbares Bodenreinigungsgerät der eingangs genannten Art derart weiterzubilden, daß der Stielhalter in einer Ruhelage zuverlässig arretiert und auf einfache Weise aus der Ruhelage in eine Arbeitslage überführt werden kann.Object of the present invention is to develop a mobile floor cleaning device of the type mentioned in such a way that the handle holder can be reliably locked in a rest position and transferred in a simple manner from the rest position to a working position.
Diese Aufgabe wird bei einem fahrbaren Bodenreinigungsgerät der gattungsgemäßen Art erfindungsgemäß dadurch gelöst, daß der Stielhalter um zwei schräg oder senkrecht zueinander ausgerichtete Schwenkachsen verschwenkbar am Gehäuse gelagert ist und in einer Ruhelage arretierbar ist, wobei jeder der beiden Schwenkachsen zur Arretierung des Stielhalters mindestens ein Arretierungselement zugeordnet ist und durch beliebiges Verschwenken des Stielhalters aus der Ruhelage um eine der beiden Schwenkachsen die Arretierung des Stielhalters bezüglich beider Schwenkachsen aufhebbar ist.This object is achieved in a mobile floor cleaning device of the generic type according to the invention that the handle holder is pivotally mounted about two obliquely or perpendicularly aligned pivot axes on the housing and can be locked in a rest position, each of the two pivot axes for locking the handle holder assigned at least one locking element is and by any pivoting of the handle holder from the rest position about one of the two pivot axes, the locking of the handle holder with respect to both pivot axes can be canceled.
Die Arretierung des Stielhalters in seiner Ruhelage erfolgt beim erfindungs- gemäßen Bodenreinigungsgerät mit Hilfe von mindestens zwei Arretierungselemente, die jeweils einer Schwenkachse zugeordnet sind. Die Arretierungselemente arretieren den Stielhalter in seiner Ruhelage jeweils bezüglich der ihnen zugeordneten Schwenkachse, das heißt mindestens ein erstes Arretie- rungselement unterbindet in der Ruhelage des Stielhalters ein Verschwenken desselben um eine erste Schwenkachse, und mindestens ein zweites Arretierungselement unterbindet in der Ruhelage des Stielhalters ein Verschwenken desselben um eine zweite Schwenkachse. Insgesamt kann dadurch eine zuverlässige, mechanisch belastbare Arretierung des Stielhalters in seiner Ruhelage erzielt werden. Soll der Stielhalter in eine Arbeitslage überführt werden, so ist es hierzu lediglich erforderlich, den Stielhalter um eine der beiden Schwenkachsen aus der Ruhelage auszuschwenken. Diese Ausschwenkbewegung hat dann zur Folge, daß die Arretierung bezüglich beider Schwenkachsen gelöst wird. Das erfindungsgemäße Kehrgerät zeichnet sich somit auch durch eine sehr einfache Handhabung aus.The locking of the handle holder in its rest position takes place in the inventive floor cleaning device with the help of at least two locking elements, which are each associated with a pivot axis. The locking elements lock the handle holder in its rest position in each case with respect to their associated pivot axis, that is at least a first Arretie- In the rest position of the handle holder, the locking element prevents it from pivoting about a first pivot axis, and at least one second locking element prevents it from pivoting about a second pivot axis in the rest position of the handle holder. Overall, this makes it possible to achieve a reliable, mechanically loadable locking of the handle holder in its rest position. If the stem holder to be transferred to a working position, so it is only necessary to swing out the stem holder about one of the two pivot axes from the rest position. This Ausschwenkbewegung then has the consequence that the lock is released with respect to both pivot axes. The sweeping device according to the invention is thus characterized by a very simple handling.
Von Vorteil ist es, wenn die Arretierungselemente in der Ruhelage des Stielhalters mit einem zwischen den Arretierungselementen angeordneten Halteteil in Eingriff stehen, wobei durch Verschwenken des Stielhalters aus der Ruhelage die Arretierungselemente das Halteteil freigeben. Durch das Zusammenwirken der Arretierungselemente mit dem Halteteil kann der Stielhalter in seiner Ruhelage in einem festen, vorgegebenen Winkel zum Gehäuse ausgerichtet werden. Die Arretierungselemente stehen hierbei mit dem Halteteil in Eingriff. Wird der Stielhalter aus der Ruhelage verschwenkt, so geben die Arretierungselemente das Halteteil frei, so daß die Arretierung des Stielhalters aufgehoben wird.It is advantageous if the locking elements in the rest position of the handle holder are engaged with a holding member arranged between the locking elements, wherein the locking elements release the holding member by pivoting the handle holder from the rest position. Due to the interaction of the locking elements with the holding part of the handle holder can be aligned in its rest position in a fixed, predetermined angle to the housing. The locking elements are in this case with the holding part in engagement. If the stem holder is pivoted out of the rest position, then the locking elements release the holding part, so that the locking of the handle holder is released.
Günstig ist es, wenn zumindest ein Arretierungselement in der Ruhelage des Stielhalters federelastisch in Richtung auf das Halteteil vorgespannt ist. Zur Vorspannung kann zumindest ein Arretierungselement mittels einer Druckfeder mit einer Kraft in Richtung auf das Halteteil beaufschlagt werden. Durch Wahl der Stärke der Druckfeder kann somit auf konstruktiv einfache Weise die zur Arretierung erforderliche Krafteinwirkung vorgegeben werden.It is advantageous if at least one locking element in the rest position of the handle holder is resiliently biased in the direction of the holding part. For biasing at least one locking element can be acted upon by means of a compression spring with a force in the direction of the holding part. Extension number The strength of the compression spring can thus be set in a structurally simple manner, the force required for locking force.
Alternativ oder ergänzend kann vorgesehen sein, daß das Halteteil in der Ruhelage des Stielhalters federelastisch in Richtung auf mindestens ein Arretierungselement vorgespannt ist.Alternatively or additionally, it may be provided that the holding part is resiliently biased in the rest position of the handle holder in the direction of at least one locking element.
Bei einer kostengünstig herstellbaren und konstruktiv einfachen Ausführungsform ist das Halteteil in der Ruhelage des Stielhalters zwischen den Arretierungselementen angeordnet. Das Halteelement kann beispielsweise zapfen- oder stiftförmig ausgebildet sein, wobei in der Ruhelage des Stielhalters an den einander abgewandten Enden des Halteteils jeweils mindestens ein Arretierungselement anliegt. Insbesondere kann vorgesehen sein, daß an den Stirnseiten des Halteteils jeweils ein Arretierungselement anliegt, so daß die beiden Arretierungselemente in der Ruhelage des Stielhalters fluchtend zueinander ausgerichtet sind. Durch Verschwenken des Stielhalters aus seiner Ruhelage kann die fluchtende Anordnung der beiden Arretierungselemente aufgegeben werden, wobei beide Arretierungselemente mit dem zwischen ihnen angeordneten Halteteil außer Eingriff gelangen, so daß die Arretierung des Stielhalters aufgegeben wird.In an economically producible and structurally simple embodiment, the holding part is arranged in the rest position of the handle holder between the locking elements. The holding element may be formed, for example, pin or pin-shaped, wherein in the rest position of the handle holder at the opposite ends of the holding member in each case bears at least one locking element. In particular, it can be provided that in each case a locking element is applied to the end faces of the holding part, so that the two locking elements are aligned in the rest position of the handle holder in alignment with each other. By pivoting the handle holder from its rest position, the aligned arrangement of the two locking elements can be abandoned, both locking elements with the holding member arranged between them disengage, so that the locking of the handle holder is abandoned.
Vorzugsweise ist das Halteteil zusammen mit dem Stielhalter um eine der beiden Schwenkachsen verschwenkbar und mindestens ein Arretierungselement ist bezüglich dieser Schwenkachse unverschwenkbar gehalten. Dadurch kann das Halteteil auf einfache Weise durch Verschwenken des Stielhalters relativ zu mindestens einem Arretierungselement bewegt werden. Zur Herstellung der Arretierung kann das Halteteil zusammen mit dem Stielhalter in eine Stellung gebracht werden, in der das mindestens eine Arretierungselement mit dem Halteteil in Eingriff gelangt und dadurch die Bewegung um die dem Arretierungselement zugeordnete Schwenkachse sperrt.Preferably, the holding part is pivotable about one of the two pivot axes together with the handle holder and at least one locking element is held non-pivotable with respect to this pivot axis. As a result, the holding part can be moved in a simple manner by pivoting the handle holder relative to at least one locking element. To produce the locking, the holding part together with the handle holder in a position be brought, in which the at least one locking element engages with the holding part in engagement and thereby blocks the movement around the pivot axis associated with the locking element.
Günstig ist es, wenn mindestens ein Arretierungselement zusammen mit dem Stielhalter um eine der Schwenkachsen verschwenkbar ist und das Halteelement bezüglich dieser Schwenkachse unverschwenkbar gehalten ist. Das mindestens eine Arretierungselement kann somit zusammen mit dem Stielhalter in eine Stellung überführt werden, in der es mit dem Halteteil in Eingriff gelangt, so daß eine Bewegung des Stielhalters um die dem Arretierungselement zugeordnete Schwenkachse gesperrt ist.It is advantageous if at least one locking element is pivotable about one of the pivot axes together with the handle holder and the retaining element is held non-pivotable with respect to this pivot axis. The at least one locking element can thus be transferred together with the handle holder in a position in which it comes into engagement with the holding part, so that a movement of the handle holder is locked to the locking element associated pivot axis.
Bei einer besonders vorteilhaften Ausführungsform ist das Halteteil in einem um eine der beiden Schwenkachsen verschwenkbar gelagerten Gelenkstück quer zu dieser Schwenkachse verschiebbar gehalten. Das Gelenkstück kann beispielsweise oberseitig am Gehäuse des Kehrgeräts um eine erste Schwenkachse verschwenkbar gelagert sein. Vorzugsweise ist die erste Schwenkachse senkrecht zur Hauptbewegungsrichtung des Bodenreinigungsgeräts ausgerichtet. Am Gelenkstück ist das Halteteil quer zur ersten Schwenkachse verschiebbar gehalten. Es kann somit zusammen mit dem Gelenkstück um die Schwenkachse verschwenkt und zusätzlich kann es senkrecht zur Schwenkachse verschoben werden.In a particularly advantageous embodiment, the holding part is held displaceably transversely to this pivot axis in a pivot piece mounted pivotably about one of the two pivot axes. The joint piece, for example, be mounted on the upper side of the housing of the sweeping device pivotable about a first pivot axis. Preferably, the first pivot axis is aligned perpendicular to the main direction of movement of the floor cleaning device. On the joint piece, the holding part is held displaceably transversely to the first pivot axis. It can thus be pivoted together with the hinge piece about the pivot axis and in addition it can be moved perpendicular to the pivot axis.
Bei einer konstruktiv einfachen Ausgestaltung ist das Halteteil als Hülse ausgestaltet. Günstig ist es, wenn die Arretierungselemente jeweils einen in der Ruhelage des Stielhalters in eine Aufnahme des Halteteils eintauchenden Kugelabschnitt aufweisen. Insbesondere können die Arretierungselemente als Kugeln ausgebildet sein, zum Beispiel als Stahlkugeln.In a structurally simple embodiment, the holding part is designed as a sleeve. It is advantageous if the locking elements each have a in the rest position of the handle holder dipping into a receptacle of the holding part ball portion. In particular, the locking elements may be formed as balls, for example as steel balls.
Vorzugsweise ist zumindest ein Arretierungselement am Stielhalter festgelegt. Es kann beispielsweise in einer Ausnehmung des Stielhalters gehalten sein, insbesondere kann es in die Ausnehmung eingepreßt sein. Die Ausnehmung kann in den Stielhalter eingeformt sein.Preferably, at least one locking element is fixed to the handle holder. It may for example be held in a recess of the handle holder, in particular it may be pressed into the recess. The recess may be formed in the handle holder.
Von Vorteil ist es, wenn die Ausnehmung in eine bogenförmige Endfläche des Stielhalters eingeformt ist.It is advantageous if the recess is formed in an arcuate end face of the handle holder.
Günstig ist es, wenn die bogenförmige Endfläche konzentrisch zu einer Schwenkachse des Stielhalters ausgestaltet ist. Dadurch kann beim Verschwenken des Stielhalters um diese Schwenkachse ein gleich bleibender Abstand zwischen der Endfläche des Stielhalters und der anderen Schwenkachse sichergestellt werden.It is advantageous if the arcuate end face is configured concentrically to a pivot axis of the handle holder. As a result, a constant distance between the end face of the handle holder and the other pivot axis can be ensured during pivoting of the handle holder about this pivot axis.
Bei einer bevorzugten Ausführungsform ist mindestens ein Arretierungselement unverschwenkbar am Gehäuse des Kehrgeräts gehalten. Durch das Verschwenken des Stielhalters in seine Ruhelage kann dann dieses Arretierungselement eine weitere Bewegung des Stielhalters um die dem Arretierungselement zugeordnete Schwenkachse sperren.In a preferred embodiment, at least one locking element is held non-pivotably on the housing of the sweeper. By pivoting the handle holder in its rest position then this locking element can block further movement of the handle holder to the locking element associated pivot axis.
Günstigerweise ist das mindestens eine am Gehäuse des Kehrgeräts gehaltene Arretierungselement zusammen mit einer Feder in einem Aufnahmeteil ange- ordnet, wobei die Feder das Arretierungselement mit einer Kraft in Richtung auf das Halteteil beaufschlagt. Die Feder kann sich an einer Stützfläche des Aufnahmeteils abstützen und das Arretierungselement mit einer Federkraft beaufschlagen zur Festlegung des Halteteils und damit zur Arretierung des Stielhalters in seiner Ruhelage.The at least one locking element held on the housing of the sweeping device is expediently arranged together with a spring in a receiving part. orders, wherein the spring acts on the locking element with a force in the direction of the holding part. The spring can be supported on a support surface of the receiving part and act on the locking element with a spring force for fixing the holding part and thus for locking the handle holder in its rest position.
Vorzugsweise weist das Aufnahmeteil einen Anschlag auf, der die Bewegung des Arretierungselements in Richtung auf das Halteteil begrenzt. Dadurch wird auf konstruktiv einfache Weise sichergestellt, daß das Arretierungselement zwar in Richtung auf das Halteteil mit einer Federkraft beaufschlagt werden kann, so daß der Stielhalter in seiner Ruhelage zuverlässig arretiert ist, wird der Stielhalter aber in eine Arbeitslage verschwenkt, so gibt das Arretierungselement das Halteteil frei, wobei es dann am Anschlag zur Anlage kommen kann. Das Arretierungselement ist somit unverlierbar im Aufnahmeteil gehalten.Preferably, the receiving part has a stop which limits the movement of the locking element in the direction of the holding part. This ensures in a structurally simple manner that the locking element can indeed be acted upon in the direction of the holding part with a spring force, so that the handle holder is reliably locked in its rest position, but the handle holder is pivoted into a working position, the locking element is the holding part free, where it can then come to the stop to the plant. The locking element is thus held captive in the receiving part.
Das Aufnahmeteil kann beispielsweise als Buchse ausgestaltet sein, die in einer Ausnehmung des Gehäuses positioniert ist. Als günstig hat es sich erwiesen, die Buchse aus Metall herzustellen, vorzugsweise aus Messing.The receiving part may for example be designed as a socket which is positioned in a recess of the housing. As low it has been proven to produce the bushing made of metal, preferably made of brass.
Bei einer besonders bevorzugten Ausführungsform der Erfindung ist das fahrbare Bodenreinigungsgerät als Kehrgerät ausgestaltet, wobei das Reinigungswerkzeug als im Gehäuse drehbar gelagerte Bürstenwalze ausgebildet ist und ein Schmutzsammelbehälter der Bürstenwalze benachbart angeordnet ist. Günstig ist es hierbei, wenn die Bürstenwalze von einem Elektromotor in Drehung versetzt werden kann. Hierbei ist es von besonderem Vorteil, wenn das Kehrgerät eine wieder aufladbare Batterie umfaßt zur Energieversorgung des Elektromotors. Vorzugsweise ist der Stielhalter dann in einem Bereich zwischen der Batterie und der Bürstenwalze am Gehäuse angelenkt. Es hat sich gezeigt, daß dadurch die Führung des Kehrgeräts an der zu kehrenden Bodenfläche entlang vereinfacht werden kann.In a particularly preferred embodiment of the invention, the mobile floor cleaning device is designed as a sweeping device, wherein the cleaning tool is designed as a rotatably mounted in the housing brush roller and a dirt collecting container of the brush roller is arranged adjacent. It is favorable in this case if the brush roller can be set in rotation by an electric motor. It is particularly advantageous if the sweeping device comprises a rechargeable battery for powering the The electric motor. Preferably, the handle holder is then articulated in a region between the battery and the brush roller on the housing. It has been shown that thereby the leadership of the sweeper can be simplified along the floor surface to be swept.
Die nachfolgende Beschreibung einer bevorzugten Ausführungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:The following description of a preferred embodiment of the invention serves in conjunction with the drawings for further explanation. Show it:
Figur 1: eine perspektivische Darstellung eines erfindungsgemäßen Bodenreinigungsgeräts;Figure 1: a perspective view of a floor cleaning device according to the invention;
Figur 2: eine Schnittansicht längs der Linie 2-2 in Figur 1;Figure 2 is a sectional view taken along the line 2-2 in Figure 1;
Figur 3: eine Schnittansicht längs der Linie 3-3 in Figur 1.3 shows a sectional view along the line 3-3 in Figure 1.
In der Zeichnung ist schematisch ein insgesamt mit dem Bezugszeichen 10 belegtes Bodenreinigungsgerät in Form eines fahrbaren Kehrgeräts dargestellt mit einem Gehäuse 12, das ein Gehäuseunterteil 13 und ein Gehäuseoberteil 14 umfaßt. Am Gehäuseunterteil 13 sind um eine gemeinsame Drehachse 16 frei drehbar zwei Laufräder 17, 18 gelagert. Im Abstand zu den Laufrädern 17, 18 sind einer Stirnseite 19 des Gehäuses 12 benachbart zwei Stützrollen um eine parallel zur Drehachse 16 drehbare Drehachse frei drehbar gelagert, wobei in der Zeichnung nur eine Stützrolle 20 erkennbar ist.In the drawing, a generally designated by the reference numeral 10 floor cleaning device in the form of a mobile sweeping device is shown with a housing 12 which includes a housing bottom 13 and a housing upper part 14. On the lower housing part 13, two wheels 17, 18 are freely rotatable about a common axis of rotation 16. At a distance from the wheels 17, 18 of an end face 19 of the housing 12 adjacent two support rollers are freely rotatably mounted about a parallel to the rotation axis 16 rotatable axis of rotation, wherein in the drawing, only one support roller 20 can be seen.
Innerhalb des Gehäuses 12 ist eine in Figur 3 erkennbare Bürstenwalze 22 um eine parallel zur Drehachse 16 ausgerichtete Drehachse drehbar gelagert, die über einen an sich bekannten und deshalb in der Zeichnung nicht dargestellten Riementrieb mit einem Elektromotor zusammenwirkt, der dem Fachmann an sich bekannt ist und deshalb zur Erzielung einer besseren Übersicht ebenfalls nicht dargestellt ist. Die Energieversorgung des Elektromotors erfolgt mittels einer wieder aufladbaren Batterie 23, und mit Hilfe eines oberseitig am Gehäuseoberteil 14 angeordneten Schalters 24 kann der Elektromotor ein- und ausgeschaltet werden. Das Gehäuse 12 nimmt außerdem einen Schmutzsammelbehälter 26 auf, der nach Art einer Schublade auf der der Stirnseite 19 abgewandten Rückseite 28 des Gehäuses 12 in das Gehäuse 12 eingeschoben und mit diesem lösbar verrastet werden kann. Der Schmutzsammelbehälter 26 weist eine Schmutzeintrittsöffnung 30 auf, die der Bürstenwalze 22 unmittelbar benachbart angeordnet ist. Schmutz, der von der Bürstenwalze 22 von der zu reinigenden Bodenfläche gekehrt wurde, kann somit über die Schmutzeintrittsöffnung 30 in den Schmutzsammelbehälter 26 überführt werden.Within the housing 12 a recognizable in Figure 3 brush roller 22 is rotatably mounted about an aligned parallel to the axis of rotation 16 axis of rotation, the cooperates via a known per se and therefore not shown in the drawing belt drive with an electric motor, which is known in the art and therefore is not shown to achieve a better overview. The power supply of the electric motor by means of a rechargeable battery 23, and with the aid of a top side of the housing upper part 14 arranged switch 24, the electric motor can be switched on and off. The housing 12 also accommodates a dirt collecting container 26 which, in the manner of a drawer, can be pushed into the housing 12 on the rear side 28 of the housing 12 facing away from the front side 19 and can be releasably latched thereto. The dirt collecting container 26 has a dirt inlet opening 30, which is arranged adjacent to the brush roller 22. Dirt that has been swept by the brush roller 22 from the bottom surface to be cleaned, can thus be transferred via the dirt inlet opening 30 in the dirt collecting 26.
Zur Führung des Kehrgeräts 10 entlang der zu reinigenden Bodenfläche weist das Kehrgerät 10 einen Stielhalter 32 auf, in den ein an sich bekannter und deshalb in der Zeichnung nicht dargestellter Stiel eingesetzt werden kann und der mittels eines Kardangelenks 34 oberseitig am Gehäuseoberteil 14 gehalten ist. Das Kardangelenk 34 ermöglicht eine Schwenkbewegung des Stielhalters um eine erste, senkrecht zur Hauptbewegungsrichtung 36 und damit parallel zur Drehachse 16 der Laufräder 17, 18 ausgerichtete Schwenkachse 38, sowie eine Schwenkbewegung um eine zweite Schwenkachse 40, die in der dargestellten Ausführungsform senkrecht zur ersten Schwenkachse 38 verläuft und im Abstand zu dieser angeordnet ist. Wie insbesondere aus Figur 2 deutlich wird, weist das Kardangelenk 34 ein Gelenkstück 42 auf mit zwei einander abgewandten, fluchtend zur ersten Schwenkachse 38 ausgerichteten Sackbohrungen 44, 45, in denen jeweils ein Gelenkstift 46 bzw. 47 angeordnet ist, der mit seinem über das Gelenkstück 42 nach außen hervorstehenden Endbereich 49 bzw. 50 in eine zugeordnete Lagerausnehmung 52 bzw. 53 des Gehäuseoberteils 14 eintaucht. Mittels einer Druckfeder 55 bzw. 56, die in der jeweiligen Sackbohrung 44 bzw. 45 angeordnet ist, werden die Gelenkstifte 46 und 47 in die zugeordneten Lageraus- nehmungen 52 bzw. 53 eingedrückt.To guide the sweeping device 10 along the bottom surface to be cleaned, the sweeping device 10 has a handle holder 32, in which a known per se and therefore not shown in the drawing stem can be used and which is held by a universal joint 34 on the upper side of the housing top 14. The universal joint 34 allows a pivoting movement of the handle holder about a first, perpendicular to the main movement direction 36 and thus parallel to the axis of rotation 16 of the wheels 17, 18 aligned pivot axis 38, and a pivoting movement about a second pivot axis 40, which in the illustrated embodiment perpendicular to the first pivot axis 38th runs and is arranged at a distance to this. As is clear in particular from Figure 2, the universal joint 34 has a hinge piece 42 with two opposite, aligned to the first pivot axis 38 blind holes 44, 45, in each of which a hinge pin 46 and 47 is arranged, with his on the joint piece 42 outwardly projecting end portion 49 and 50 in an associated bearing recess 52 and 53 of the housing upper part 14 is immersed. By means of a compression spring 55 or 56, which is arranged in the respective blind bore 44 or 45, the hinge pins 46 and 47 in the associated Lageraus- recesses 52 and 53 are pressed.
Das Gelenkstück 42 ist mit Hilfe der Gelenkstifte 46, 47 um die erste Schwenkachse 38 verschwenkbar am Gehäuseoberteil 14 gelagert.The hinge piece 42 is mounted on the housing upper part 14 so as to be pivotable about the first pivot axis 38 by means of the hinge pins 46, 47.
Zwischen den beiden Sackbohrungen 44 und 45 weist das Gelenkstück 42 eine senkrecht zur ersten Schwenkachse 38 ausgerichtete Durchgangsbohrung 58 auf, die sich in die dem Gehäuseoberteil 14 abgewandte Richtung über eine Stufe 59 erweitert. Die Durchgangsbohrung 58 nimmt ein Halteteil in Form einer Hülse 61 auf, die in der Durchgangsbohrung 58 verschiebbar gehalten ist und aus einem Metall oder einem hochwertigen Kunststoff gefertigt ist.Between the two blind holes 44 and 45, the joint piece 42 has a perpendicular to the first pivot axis 38 aligned through hole 58, which widens in the upper housing 14 remote from the direction of a step 59. The through hole 58 receives a holding part in the form of a sleeve 61, which is slidably held in the through hole 58 and is made of a metal or a high-quality plastic.
Die Durchgangsbohrung 58 mündet auf ihrer dem Gehäuseoberteil 14 abgewandten Endseite in einen Aufnahmeraum 63 des Gelenkstücks 42, der ein Endstück 65 des Stielhalters 32 aufnimmt. Der Stielhalter 32 ist im Bereich des Aufnahmeraums 63 um die zweite Schwenkachse 40 verschwenkbar an das Gelenkstück 42 angelenkt. Die der Hülse 61 zugewandte Endfläche 67 des Stielhalters 32 ist kreisbogenförmig und konzentrisch zur zweiten Schwenkachse 40 ausgestaltet. Fluchtend zu einer Längsachse 69 des Stielhalters 32 ist in die Endfläche 67 eine Ausnehmung 70 eingeformt, in die ein erstes Arretierungselement in Form einer ersten Arretierungskugel 72 eingepreßt ist. Diese steht mit einem Kugelabschnitt über die Ausnehmung 70 in Richtung der Hülse 61 hervor.The through hole 58 opens on its side facing away from the upper housing part 14 end side into a receiving space 63 of the joint piece 42 which receives an end piece 65 of the handle holder 32. The handle holder 32 is articulated in the region of the receiving space 63 about the second pivot axis 40 pivotally connected to the joint piece 42. The sleeve 61 facing end surface 67 of the handle holder 32 is circular arc and concentric with the second pivot axis 40 configured. Escaping to a longitudinal axis 69 of the handle holder 32 is formed in the end face 67 a recess 70, in which a first locking element in the form of a first locking ball 72 is pressed. This protrudes with a ball portion on the recess 70 in the direction of the sleeve 61.
Der Stielhalter 32 ist in Figur 1 in einer Arbeitslage dargestellt, in der er um die beiden Schwenkachsen 38, 40 frei verschwenkbar ist. Die Figuren 2 und 3 zeigen den Stielhalter 32 in einer Ruhelage, in der er mit vorgegebener Ausrichtung, in der dargestellten Ausführungsform mit vertikaler Ausrichtung, arretiert ist . In der Ruhelage fluchtet die Längsachse 69 des Stielhalters 32 mit der Achse 74 einer zylindrischen Gehäuseausnehmung 75 des Gehäuseoberteils 14, in die ein zylinderförmiges Aufnahmeteil 77 eingepreßt ist. Das Aufnahmeteil 77 nimmt eine Druckfeder 78 und ein zweites Arretierungselement in Form einer zweiten Arretierungskugel 79 auf. Die zweite Arretierungskugel 79 wird hierbei von der Druckfeder 78 mit einer Federkraft in Richtung auf die Hülse 61 beaufschlagt. Ein radial nach innen gerichteter Rand 81 an der der Hülse 61 zugewandten Stirnseite des Aufnahmeteils 77 bildet einen Anschlag, an dem die zweite Arretierungskugel 79 anliegt, wenn der Stielhalter 32 eine Arbeitslage einnimmt.The handle holder 32 is shown in Figure 1 in a working position in which it is freely pivotable about the two pivot axes 38, 40. Figures 2 and 3 show the handle holder 32 in a rest position in which it is locked with a predetermined orientation, in the illustrated embodiment with a vertical orientation. In the rest position, the longitudinal axis 69 of the handle holder 32 is aligned with the axis 74 of a cylindrical housing recess 75 of the upper housing part 14, in which a cylindrical receiving part 77 is pressed. The receiving part 77 receives a compression spring 78 and a second locking element in the form of a second locking ball 79. The second locking ball 79 is in this case acted upon by the compression spring 78 with a spring force in the direction of the sleeve 61. A radially inwardly directed edge 81 on the sleeve 61 facing the end face of the receiving part 77 forms a stop on which the second Arretierungskugel 79 abuts when the handle holder 32 occupies a working position.
In der Ruhelage des Stielhalters 32 sind die beiden Arretierungskugeln 72 und 79 fluchtend zueinander ausgerichtet und stehen mit der Hülse 61 in Eingriff. Die zweite Arretierungskugel 79 wird hierbei von der Druckfeder 78 in Richtung auf die Hülse 61 vorgespannt, die die Federkraft auf die erste Arretierungskugel 72 überträgt, so daß sich insgesamt eine stabile Lage des Stielhalters 32 ergibt, wie sie in den Figuren 2 und 3 dargestellt ist. Wird der Stielhalter 32 ausgehend von seiner Ruhelage um die erste Schwenkachse 38 verschwenkt, so gelangt die zweite Arretierungskugel 79 mit der Hülse 61 außer Eingriff und legt sich aufgrund der auf sie einwirkenden Federkraft am Rand 81 an. Aufgrund ihrer Gewichtskraft verschiebt sich dann die Hülse 61 innerhalb der Durchgangsbohrung 58 so weit nach unten, bis sie mit einem der zweiten Arretierungskugel 79 abgewandten Bund 83 an der Stufe 59 der Durchgangsbohrung 58 anliegt. Zum Ausgleich von Fertigungstoleranzen kann zwischen dem Bund 83 und der Stufe 59 eine Feder angeordnet sein, die durch die Gewichtskraft der Hülse 61 zusammengedrückt wird. Die Bewegung der Hülse 61 hat zur Folge, daß die Hülse 61 auch mit der ersten Arretierungskugel 72 außer Eingriff gelangt und somit die Arretierung des Stielhalters 32 sowohl bezüglich seiner ersten Schwenkachse 38 als auch seiner zweiten Schwenkachse 40 aufgehoben wird. Der Stielhalter 32 kann nunmehr eine beliebige Arbeitslage einnehmen und ist um die Schwenkachsen 38, 40 frei verschwenkbar.In the rest position of the handle holder 32, the two locking balls 72 and 79 are aligned with each other and are engaged with the sleeve 61 in engagement. The second locking ball 79 is biased by the compression spring 78 in the direction of the sleeve 61, which transmits the spring force to the first Arretierungskugel 72, so that overall results in a stable position of the handle holder 32, as shown in Figures 2 and 3 , If the handle holder 32 is pivoted about its first pivot axis 38, starting from its rest position, then the second locking ball 79 disengages from the sleeve 61 and bears against the rim 81 due to the spring force acting on it. Due to its weight, then the sleeve 61 moves within the through hole 58 so far down until it abuts with a second detent ball 79 facing away from the collar 83 on the step 59 of the through hole 58. To compensate for manufacturing tolerances may be arranged between the collar 83 and the step 59, a spring which is compressed by the weight of the sleeve 61. The movement of the sleeve 61 has the consequence that the sleeve 61 is also disengaged from the first locking ball 72 and thus the locking of the handle holder 32 is canceled both with respect to its first pivot axis 38 and its second pivot axis 40. The handle holder 32 can now assume any working position and is freely pivotable about the pivot axes 38, 40.
Wird der Stielhalter 32 ausgehend von seiner Ruhelage um die zweite Schwenkachse 40 verschwenkt, so gibt die in die Ausnehmung 70 eingepreßte erste Arretierungskugel 72 die Hülse 61 frei, die sich daraufhin aufgrund der von der Druckfeder 78 über die zweite Arretierungskugel 79 auf sie einwirkenden Federkraft innerhalb der Durchgangsbohrung 58 so weit nach oben verschiebt, bis sie an der bogenförmigen Endfläche 67 des Stielhalters 32 anliegt. Die zweite Arretierungskugel 79 bewegt sich hierbei bis an den Rand 81. Dieser unterbindet eine weitere Beaufschlagung der Hülse 61 mit einer Kraft von der Druckfeder 78. Somit wird beim Verschwenken des Stielhalters 32 ausgehend aus seiner Ruhelage um die zweite Schwenkachse 40 auch die Arretie- rung des Stielhalters um die erste Schwenkachse 38 aufgehoben. Der Stielhalter 32 kann nunmehr eine beliebige Arbeitslage einnehmen.If the handle holder 32 is pivoted from its rest position about the second pivot axis 40, so the pressed into the recess 70 first Arretierungskugel 72, the sleeve 61 free, which then due to the force acting on the compression spring 78 via the second Arretierungskugel 79 spring force within the through hole 58 moves so far up until it rests against the arcuate end surface 67 of the handle holder 32. The second locking ball 79 in this case moves to the edge 81. This prevents further loading of the sleeve 61 with a force from the compression spring 78. Thus, when pivoting the handle holder 32 from its rest position about the second pivot axis 40 and the Arretierungs tion of the handle holder lifted around the first pivot axis 38. The handle holder 32 can now assume any working position.
Aus dem voranstehenden wird deutlich, daß der Stielhalter 32 in seiner Ruhelage zuverlässig mittels der Arretierungskugeln 72 und 79 arretiert werden kann, die jeweils die Arretierung des Stielhalters 32 bezüglich einer der beiden Schwenkachsen 38 und 40 sicherstellen. Durch einfaches Ausschwenken aus der Ruhelage um die erste oder die zweite Schwenkachse 38 bzw. 40 kann die Arretierung bezüglich beider Schwenkachsen 38 und 40 auf einfache Weise wieder gelöst werden. From the above it is clear that the handle holder 32 can be reliably locked in its rest position by means of the Arretierungskugeln 72 and 79, which each ensure the locking of the handle holder 32 with respect to one of the two pivot axes 38 and 40. By simply swinging out of the rest position about the first or the second pivot axis 38 and 40, the lock with respect to both pivot axes 38 and 40 can be solved in a simple manner again.
