Description

Die Erfindung betrifft ein Bodenreinigungsgerät mit einer Bodenplatte und einer gelenkig mit dieser verbundenen Stielhaltehülse, in die ein Kuppelstück des Stiels einsetzbar ist, das in der Stielhaltehülse befestigbar ist, wobei in der Wand der Stielhaltehülse mindestens eine an ihrem freien Ende in radialer Richtung auslenkbare Rastzunge vorgesehen ist, an der eine nach innen abstehende Rastnase angeordnet ist, und das Kuppelstück mindestens eine Rastvertiefung aufweist, wobei das Kuppelstück unter einer radial nach außen gerichteten Auslenkung der mindestens einen Rastzunge der Stielhaltehülse in die Stielhaltehülse einführbar ist und die Rastnase der Rastzunge der Stielhaltehülse in die Rastvertiefung des Kuppelstücks einschnappbar ist, wobei zur Verriegelung des in die Stielhaltehülse eingesetzten und in dieser befestigten Kuppelstücks an der Außenseite der Stielhaltehülse ein Sperrschieber verschiebbar gelagert ist, der in seiner das Kuppelstück verriegelnden Stellung mit einer starren Wand an der Außenseite von mindestens einer Rastzunge der Stielhaltehülse anliegt und eine Auslenkung dieser Rastzunge nach außen blockiert, wobei der Sperrschieber die Stielhaltehülse hülsenförmig umgibt und in achsialer Richtung der Stielhaltehülse gegenüber dieser verschiebbar ist, wobei er in seiner in Richtung zur Bodenplatte verschobenen Endstellung die eine oder mehreren Rastzungen freigibt und in seiner in Richtung zum freien Ende der Stielhaltehülse verschobenen Endstellung eine Auslenkung von mindestens einer Rastzunge nach außen blockiert.The invention relates to a floor cleaning device with a bottom plate and a hinged associated with this handle holding sleeve into which a coupling piece of the handle is inserted, which is fastened in the handle holding sleeve, wherein provided in the wall of the handle holding sleeve at least one deflectable at its free end in the radial direction locking tongue is, on which an inwardly projecting locking lug is arranged, and the coupling piece has at least one latching recess, wherein the coupling piece under a radially outwardly directed deflection of the at least one latching tongue of the handle holding sleeve is inserted into the handle holding sleeve and the latching lug of the latching tongue of the handle holding sleeve in the Locking recess of the coupling piece can be snapped, wherein for locking the inserted into the handle holding sleeve and fixed in this coupling piece on the outside of the handle holding sleeve a locking slide is slidably mounted, in its locking the coupling piece Ste With a rigid wall on the outside of at least one latching tongue of the handle holding sleeve and a deflection of this latching tongue blocked to the outside, wherein the locking slide sleeve surrounds the handle sleeve and in the axial direction of the handle holding sleeve against this is displaceable, wherein it is in his direction towards the bottom plate shifted end position, the one or more locking tongues releases and blocked in its towards the free end of the handle holding sleeve displaced end position a deflection of at least one latching tongue to the outside.

Ein solches Gerät ist aus der DE 2 448 877 bekannt.Such a device is out of the DE 2 448 877 known.

Solche Bodenreinigungsgeräte, an denen zur Reinigung einer Fläche ein Bodenreinigungstuch anbringbar ist, sind in unterschiedlichen Ausführungsformen bekannt. Mit solchen Bodenreinigungsgeräten sind nicht nur Bodenflächen sondern auch Wandflächen, beispielsweise verflieste Wände, oder Deckenflächen reinigbar.Such floor cleaning devices to which a floor cleaning cloth can be attached for cleaning a surface, are known in different embodiments. With such floor cleaning devices are not only floor surfaces but also wall surfaces, such as tiled walls, or ceiling surfaces cleanable.

Zur Verbindung der Bodenplatte mit einem Stiel sind im Zusammenhang mit solchen Bodenreinigungsgeräten verschiedene Stielhalterungen bekannt geworden. Beispielsweise kann eine gelenkig mit der Bodenplatte verbundene Stielhaltehülse ein Innengewinde aufweisen, in die ein mit einem Außengewinde versehenes Kuppelstück des Stiels einschraubbar ist. Nachteilig an dieser Stielhalterung ist es, daß die Verbindung des Stiels mit der Bodenplatte relativ mühsam ist und daß sich diese Verbindung während des Betriebes unbeabsichtigt lösen kann, so daß die drehfeste Führung der Bodenplatte gegenüber dem Stiel verloren geht und die Verbindung wieder angezogen werden muß.To connect the bottom plate with a handle different handle holders have become known in connection with such floor cleaning devices. For example, a handle connected to the bottom plate stem holding sleeve having an internal thread into which a provided with an external thread coupling piece of the stem can be screwed. A disadvantage of this handle mount is that the connection of the stem to the bottom plate is relatively cumbersome and that This connection can be inadvertently released during operation, so that the rotationally fixed leadership of the bottom plate is lost relative to the stem and the connection must be tightened again.

Bekannt ist weiters eine Klemmverbindung zwischen einer Stielhaltehülse und einem konisch ausgebildeten Kuppelstück, wobei das Kuppelstück bis zur klemmenden Halterung des Kuppelstücks in der Stielhaltehülse in diese eingeschoben wird. Nachteilig hierbei ist es, daß bei einer zu geringen Klemmung sich die Bodenplatte während des Betriebes unbeabsichtigt lösen kann, während bei einer zu festen Verklemmung ein Herausziehen des Kuppelstücks aus der Stielhaltehülse nur unter großem Kraftaufwand möglich ist.Also known is a clamping connection between a handle holding sleeve and a conically shaped coupling piece, wherein the coupling piece is inserted into the handle holding sleeve until it is clamped in position of the coupling piece. The disadvantage here is that with too little clamping, the bottom plate can inadvertently come loose during operation, while in a too tight deadlock withdrawal of the coupling piece from the handle holding sleeve is possible only with great effort.

Bei einer weiteren vorbekannten Stielhafterung weist das Kuppelstück eine Durchgangsbohrung auf, mit welcher bei einer bestimmten Drehstellung des Kuppelstücks gegenüber der Stielhaltehülse in der Stielhaltehülse angeordnete, diametral gegenüberliegende Öffnungen fluchten. Zur Befestigung des Kuppelstücks in der Stielhaltehülse ist ein Arretierstift vorgesehen, welcher durch eine Öffnung der Stielhaltehülse, durch die Durchgangsbohrung des Kuppelstücks sowie durch die gegenüberliegende Öffnung in der Stielhaltehülse gesteckt wird. Eine solche Stielhalterung ist auch aus der DE 19 916 555 A1 bekannt. Damit sich beim Einschieben des Kuppelstücks in die Stielhaltehülse eine selbsttätige Ausrichtung der Drehlage des Kuppelstücks gegenüber der Stielhaltehülse ergibt, so daß die Öffnungen in der Stielhaltehülse mit der Bohrung im Kuppelstück fluchten, sind bei dieser vorbekannten Stielhalterung am vorderen Ende des Kuppelstückes und im Boden der Stielhaltehülse einander zugeordnete Schrägflächen vorgesehen. Nachteilig an dieser Stielhalterung ist es insbesondere, daß der ein relativ kleines Einzelteil bildende Arretierstift verloren gehen kann, beispielsweise wenn er nach dem Herausziehen aus der Stielhaltehülse und dem Entfernen des Kuppelstücks verlegt wird.In another prior art stalk attachment, the coupling piece has a through hole, with which at a certain rotational position of the coupling piece relative to the handle holding sleeve in the handle holding sleeve arranged, diametrically opposite openings are aligned. For fixing the coupling piece in the handle holding sleeve, a locking pin is provided, which is inserted through an opening of the handle holding sleeve, through the through hole of the coupling piece and through the opposite opening in the handle holding sleeve. Such a handle mount is also from the DE 19 916 555 A1 known. This results in the insertion of the coupling piece in the handle holding sleeve an automatic alignment of the rotational position of the coupling piece relative to the handle holding sleeve, so that the openings in the handle holding sleeve are aligned with the hole in the coupling piece, in this prior art handle holder at the front end of the coupling piece and in the bottom of the handle holding sleeve provided mutually associated inclined surfaces. A disadvantage of this handle mount, in particular, that the relatively small item forming locking pin can be lost, for example, if it is moved after pulling out of the handle holding sleeve and the removal of the coupling piece.

Die DE 24 48 877 zeigt eine Stielhaltehülse in die ein Kuppelstück des Stiels einschraubbar und mittels Rastzunge gegen Verdrehen sicherbar ist. Die Rastzunge ist über einen gattungsgemäßen Sperrschieber sicherbar.The DE 24 48 877 shows a handle holding sleeve into which a coupling piece of the handle can be screwed and secured against rotation by means of latching tongue. The catch tongue is securable via a generic gate valve.

Aufgabe der Erfindung ist es, ein Bodenreinigungsgerät mit einer verbesserten Stielhalterung bereitzustellen, die einerseits einen großen Grad an Beweglichkeit der Bodenplatte gegenüber dem Stiel ermöglicht, andererseits aber auch eine einfache Art der Arretierung des Stiels bereitstellt. Erfindungsgemäß gelingt dies durch ein Bodenreinigungsgerät mit den Merkmalen des Anspruchs 1.The object of the invention is to provide a floor cleaning device with an improved handle mount, on the one hand allows a high degree of mobility of the bottom plate relative to the stem, on the other hand, a provides simple way of locking the stem. According to the invention, this is achieved by a floor cleaning appliance having the features of claim 1.

Zur Befestigung des Stiels wird bei einem erfindungsgemäßen Bodenreinigungsgerät somit das Kuppelstück in die Stielhaltehülse eingeschoben und gegebenenfalls gegenüber der Stielhaltehülse verdreht, bis die Rastnase der mindestens einen Rastzunge in die Rastvertiefung einschnappt. An der Außenseite der Stielhaltehülse ist weiters ein verschiebbar gelagerter Sperrschieber vorgesehen, der als eine die Stielhaltehülse umgebende Hülse ausgebildet ist. In seiner das Kuppelstück verriegelnden Stellung liegt eine starre Wand dieses Sperrschiebers an der Außenseite von mindestens einer Rastzunge an und blockiert eine Auslenkung dieser Rastzunge nach außen. Ein Herausziehen der Rastnase dieser Rastzunge aus der Rastvertiefung des Kuppelstücks wird dadurch verhindert.For attachment of the stem, the coupling piece is thus inserted into the handle holding sleeve and optionally rotated relative to the handle holding sleeve until the locking lug of the at least one locking tongue snaps into the detent recess in a floor cleaning device according to the invention. On the outside of the handle holding sleeve, a slidably mounted locking slide is further provided, which is designed as a sleeve surrounding the handle holding sleeve. In its position locking the coupling piece, a rigid wall of this locking slide rests on the outside of at least one latching tongue and blocks a deflection of this latching tongue outwardly. Pulling out the locking lug of this locking tongue from the detent recess of the coupling piece is prevented.

Vorteilhaft ist es weiters, wenn das Kuppelstück an seinem vorderen Ende mit einer derartigen konischen Verjüngung ausgebildet ist und/oder die Rastnasen der Rastzungen der Stielhaltehülse in Richtung zur Einführöffnung der Stielhaltehülse derart abgeschrägt sind, daß beim Einschieben des Kuppelstücks die Rastzungen der Stielhaltehülse nach außen ausgelenkt werden. Zum Einführen des Kuppelstücks in die Stielhaltehülse und seiner Verrastung in diesem sind somit keine weiteren Manipulationen an den Teilen der Rastverbindung erforderlich.It is also advantageous if the coupling piece is formed at its front end with such a conical taper and / or the locking lugs of the locking tongues of the handle holding sleeve are tapered towards the insertion of the handle holding sleeve so that deflected when inserting the coupling piece, the locking tongues of the handle holding sleeve to the outside become. For insertion of the coupling piece in the handle holding sleeve and its latching in this no further manipulation of the parts of the latching connection are thus required.

Die Bodenplatte 1 des in den Fig. dargestellten Ausführungsbeispiels eines erfindungsgemäßen Bodenreinigungsgerätes umfaßt zwei an einem Sockel 2 um Schwenkachsen 3 verschwenkbar gelagerte Schwenkplatten 4, die in einer im wesentlichen in einer Ebene liegenden Stellung, wie diese in den Fig. dargestellt ist, gegenüber dem Sockel 2 arretierbar sind. Zum Lösen dieser Arretierung ist ein Betätigungshebel 5 vorgesehen, worauf die Schwenkplatten in Fig. 1 gesehen nach unten abschwenkbar sind. Bodenreinigungsgeräte mit verschwenkbaren Schwenkplatten sind von unterschiedlichen herkömmlichen Bodenreinigungsgeräten her bekannt und können beispielsweise in einer solchen bekannten Weise ausgebildet sein. Dies gilt auch für die an den Schwenkplatten 4 verschwenkbar gelagerten und gegenüber den Schwenkplatten verrastbaren Tuchhalteplatten 6. Zur Reinigung einer Boden-, Wand- oder Deckenfläche kann ein an der Unterseite der Bodenplatte 1 angeordnetes Bodenreinigungstuch mit dieser verbunden werden, beispielsweise mittels der Tuchhalteplatten 6 oder mittels an der Oberseite des Bodenreinigungstuchs angeordneten Laschen, in die die seitlichen Enden der Schwenkplatten 4 einführbar sind.The base plate 1 of the embodiment shown in FIGS. A floor cleaning device according to the invention comprises two on a base 2 about pivot axes 3 pivotally mounted pivot plates 4, which is in a lying substantially in a plane position, as shown in the Fig., With respect to the base 2 are lockable. To release this locking an actuating lever 5 is provided, after which the pivot plates in Fig. 1 seen are swung downwards. Floor cleaning devices with pivoting pivot plates are known from various conventional floor cleaning devices ago and can, for example, in such a known manner be educated. This also applies to the pivotally mounted on the pivot plates 4 and locked against the pivot plates cloth holding plates 6. To clean a floor, wall or ceiling surface arranged on the bottom of the bottom plate 1 floor cleaning cloth can be connected to this, for example by means of cloth holding plates 6 or by means arranged on the top of the floor cleaning cloth tabs in which the lateral ends of the pivot plates 4 are inserted.

Mit dem Sockel 2 der Bodenplatte 1 ist eine Stielhaltehülse 7 über ein Kreuzgelenk 8 verbunden. Das Kreuzgelenk 8 besitzt die beiden rechtwinklig zueinanderstehenden Schwenkachsen 9, 10. Die Stielhaltehülse 7 besitzt auf ihrer vom Kreuzgelenk 8 abgewandten Seite eine Einführöffnung 11, in die ein Kuppelstück 12 eines Stiels einführbar ist. Der Stielschaft 13, der teleskopierbar ausgebildet sein kann, ist in den Fig. 1, 2, 4 und 5 mit seinem endseitigen Abschnitt strichliert angedeutet.With the base 2 of the bottom plate 1, a stem holding sleeve 7 is connected via a universal joint 8. The universal joint 8 has the two mutually perpendicular pivot axes 9, 10. The handle holding sleeve 7 has on its side facing away from the universal joint 8 side an insertion opening 11 into which a coupling piece 12 of a handle can be inserted. The shaft shaft 13, which may be telescopic, is in the Fig. 1 . 2 . 4 and 5 indicated by dashed lines with its end section.

In der Wand der Stielhaltehülse 7 sind durch Schlitze zwei diametral gegenüberliegende Rastzungen 14 freigestellt, die in achsialer Richtung der Stielhaltehülse 7 verlaufen und eine gewisse Elastizität besitzen, so daß ihre freien Enden in radialer Richtung auslenkbar sind. An den Rastzungen 14 ist jeweils eine nach innen abstehende und in der unausgelenkten Stellung der Rastzunge über die innere Umfangsfläche 15 der Wand der Stielhaltehülse 7 vorstehende Rastnase 16 angeordnet.In the wall of the handle holding sleeve 7 are two diametrically opposed locking tongues 14 are released by slots, which extend in the axial direction of the handle holding sleeve 7 and have a certain elasticity, so that their free ends are deflected in the radial direction. At the locking tongues 14 each one inwardly projecting and in the undeflected position of the latching tongue over the inner peripheral surface 15 of the wall of the handle holding sleeve 7 projecting locking lug 16 is arranged.

Das Kuppelstück 12 weist auf radial gegenüberliegenden Seiten Rastvertiefungen 17 auf und ist zu seinem vorderen freien Ende hin mit einer gewissen konischen Verjüngung ausgebildet.The coupling piece 12 has locking recesses 17 on radially opposite sides and is formed with a certain conical taper towards its front free end.

Beim Einschieben des Kuppelstücks 12 in die Stielhaltehülse 7 werden die Rastzungen 14 vom Kuppelstück zunächst radial nach außen ausgelenkt. Wenn nach dem Einschieben des Kuppelstücks bis zum Anschlag 18, der durch eine Verringerung des Durchmessers der Stielhaltehülse gebildet wird, die Rastnasen 16 nicht in die Rastvertiefungen 17 einschnappen, wird der Stiel mit dem Koppelstück 12 verdreht, bis die Rastnasen 16 in die Rastvertiefungen 17 einschnappen. Eine erste Befestigung des Kuppelstückes 12 in der Stielhaltehülse 7 ist damit erreicht.When inserting the coupling piece 12 in the handle holding sleeve 7, the locking tongues 14 are initially deflected by the coupling piece radially outward. If, after the insertion of the coupling piece up to the stop 18, which is formed by a reduction in the diameter of the handle holding sleeve, the locking lugs 16 do not snap into the locking recesses 17, the stem is rotated with the coupling piece 12 until the locking lugs 16 snap into the locking recesses 17 , A first attachment of the coupling piece 12 in the handle holding sleeve 7 is thus achieved.

Zur Verriegelung des in die Stielhaltehülse 7 eingesetzten und in dieser über den beschriebenen Rastverschluß befestigten Kuppelstücks 12 ist weiters ein hülsenförmiger Sperrschieber 19 vorgesehen, der die Stielhaltehülse 7 außen umgibt und gegenüber dieser in achsialer Richtung der Stielhaltehülse 7 verschiebbar ist. In der in Richtung zum freien Ende der Stielhaltehülse 7 verschobenen Endstellung des hülsenförmigen Sperrschiebers 19 liegt die starre Außenwand des Sperrschiebers 19 an der Außenseite von einer der beiden Rastzungen 14 an (die in Fig. 1 auf der Rückseite der Stielhaltehülse 7 und in Fig. 5 obenliegende Rastzunge 14).To lock the inserted into the handle holding sleeve 7 and secured in this via the snap-lock described coupling piece 12 is further provided a sleeve-shaped locking slide 19 which surrounds the handle holding sleeve 7 outside and against this in the axial direction of the handle holding sleeve 7 is displaceable. In the displaced towards the free end of the handle holding sleeve 7 end position of the sleeve-shaped locking slide 19, the rigid outer wall of the locking slide 19 is located on the outside of one of the two locking tongues 14 (in Fig. 1 on the back of the handle holding sleeve 7 and in Fig. 5 overhead latching tongue 14).

Im Sperrschieber 19 ist weiters ein durch Schlitze gegenüber der Wand des Sperrschiebers freigestellte Rastzunge 20 vorgesehen, an welcher eine nach innen abstehende Rastnase 21 angeordnet ist. Die Rastzunge ist in radialer Richtung federelastisch auslenkbar und in der unausgelenkten Stellung der Rastzunge 20 steht die Rastnase 21 über die Innenfläche des Sperrschiebers vor. An der Außenseite der Stielhaltehülse 7 ist eine dieser Rastnase 21 der Rastzunge 20 des Sperrschiebers 19 zugeordnete Rastvertiefung 22 vorgesehen, die hier an der Außenseite von der in Fig. 1 vorne liegenden Rastzunge 14 der Stielhaltehülse 7 eingebracht ist. In der in Richtung zum freien Ende der Stielhaltehülse 7 verschobenen Endstellung des Sperrschiebers 19 ist die Rastnase 21 des Sperrschiebers in die Rastvertiefung 22 einschnappbar, so daß der Sperrschieber 19 in der verriegelten Stellung des Kuppelstücks 12 gegenüber einer axialen Verschiebung auf der Stielhaltehülse 7 gesichert ist.In the locking slide 19 is further provided by slots opposite the wall of the locking slide latching tongue 20 is provided, on which an inwardly projecting locking lug 21 is arranged. The latching tongue is resiliently deflectable in the radial direction and in the undeflected position of the latching tongue 20, the latching lug 21 projects beyond the inner surface of the latching slide. On the outside of the handle holding sleeve 7, one of these locking lug 21 of the latching tongue 20 of the locking slide 19 associated latching recess 22 is provided here on the outside of the in Fig. 1 front latching tongue 14 of the handle holding sleeve 7 is introduced. In the displaced towards the free end of the handle holding sleeve 7 end position of the locking slide 19, the locking lug 21 of the locking slide is snap-fitted into the locking recess 22, so that the locking slide 19 is secured in the locked position of the coupling piece 12 against axial displacement on the handle holding sleeve 7.

Eine Verdrehsicherung zur Verhinderung einer Verdrehung des Sperrschiebers 19 gegenüber der Stielhaltehülse 7 wird von einer in axialer Richtung verlaufenden Feder 23 an der Stielhaltehülse und einer dieser zugeordneten Nut 24 an der Innenfläche des Sperrschiebers gebildet.An anti-rotation to prevent rotation of the locking slide 19 relative to the handle holding sleeve 7 is formed by a spring 23 extending in the axial direction of the handle holding sleeve and a groove 24 associated therewith on the inner surface of the locking slide.

Die Rastzunge 20 des Sperrschiebers 19 mit der Rastnase 21 und die Rastvertiefung 22 der Stielhaltehülse 7 könnten grundsätzlich auch an anderen einander zugeordneten Stellen des Sperrschiebers 19 bzw. der Stielhaltehülse 7 angeordnet sein.The latching tongue 20 of the locking slide 19 with the latching lug 21 and the latching recess 22 of the handle holding sleeve 7 could in principle also be arranged at other positions of the latching slide 19 or the handle holding sleeve 7 assigned to one another.

In seiner in Richtung zur Bodenplatte 1 verschobenen Endstellung des hülsenförmigen Sperrschiebers 19 umgibt dieser das Kreuzgelenk 8 und blockiert dieses.In its displaced in the direction of the bottom plate 1 end position of the sleeve-shaped locking slide 19, this surrounds the universal joint 8 and blocks it.

Denkbar und möglich wäre es auch an der Stielhaltehülse 7 lediglich eine einzelne Rastzunge 14 vorzusehen, deren Rastnase 16 mit einer Rastvertiefung 17 im Kuppelstück 12 zusammenwirkt. Auch mehr als zwei solcher Rastzungen 14 könnten vorgesehen sein. Diese Rastzungen 14 könnten auch vom freien Ende der Stielhaltehülse 7 ausgehen.Conceivable and possible, it would also be provided on the handle holding sleeve 7 only a single latching tongue 14, the latching lug 16 cooperates with a latching recess 17 in the coupling piece 12. Also, more than two such locking tongues 14 could be provided. These locking tongues 14 could also emanate from the free end of the handle holding sleeve 7.
