Stand der TechnikState of the art

Ein derartiges Bodenwischgerät ist aus der WO 97 24 973 A bekannt. Die Verrastung erfolgt radial durch den Eingriff einer Spannzange in ein Zahnrad mit einer Rastverzahnung. Nachteilig ist hierbei, daß konstruktionsbedingt nur einige wenige Anschlagsflächen in Eingriff sind, so daß gerade auf diesen Flächen ein hoher Verschleiß auftritt. Da zudem die gegen eine Feder wirkende Spannzange die notwendigen Stallkräfte aushalten muß, ist eine entsprechend hohe Federstärke erforderlich, wodurch die Betätigung zusätzlich erschwert wird. Such a floor mopping device is known from WO 97 24 973 A. The latch takes place radially by the engagement of a collet with a gear a locking toothing. The disadvantage here is that, due to the design, only a few stop surfaces are engaged, so that just on this Areas of high wear occurs. Since also the one acting against a spring Collet must withstand the necessary stall forces, is one accordingly high spring strength required, which makes operation even more difficult becomes.

Ein anderes Bodenwischgerät ist aus der US-A-5.509.163 bekannt, die die Relatiwerdrehungen der Hülse auf dem Schaft verhindernden Anschläge sind dabei dem Schaft zugeordnet. Sie werden durch eine Vielzahl gleichmäßig in Umfangsrichtung verteilter Rippen gebildet, die sich parallel zu der Achse des Schaftes erstrecken. Ihre Anformung an den Schaft ist mit einem großen Werkzeugaufwand verbunden. Es ist zwar möglich, die Anzahl der Rippen auf zwei zu beschränken, was deren Anformung erleichtert. Sie gelangen dann aber im Normalfall erst nach einer mehr oder weniger großen Rückwärtsverdrehung der Hülse mit dem durch eine Sperrklinke gebildeten Gegenanschlag in Eingriff, was es verhindert, eine hinreichende Entwässerung der Streifen nach einer vorausgegangenen Benetzung mit Wasser zu erzielen.Another floor mopping device is known from US-A-5,509,163, which the Relative rotations of the sleeve on the shaft are preventing stops assigned to the shaft. They are evenly in through a variety Circumferential direction of distributed ribs formed, which are parallel to the axis of the Extend shaft. Their shape on the shaft is large Tool effort connected. It is possible to increase the number of ribs to limit two, which facilitates their molding. You will then arrive but normally only after a more or less large reverse rotation the sleeve with the one Pawl formed counter stop in engagement, which prevents it from being sufficient Strip drainage after previous wetting to achieve with water.

Die Sperrklinke ist bei der bekannten Ausführung in der Hülse angeordnet. Sie ist aus Platzgründen sehr klein dimensioniert und dementsprechend in mechanischer Hinsicht sehr empfindlich.The pawl is arranged in the known embodiment in the sleeve. It is dimensioned very small for reasons of space and accordingly in mechanically very sensitive.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Bodenwischgerät der eingangs erwähnten Art derart weiterzuentwickeln, daß sich bei einer vereinfachten Herstellbarkeit eine größere Robustheit ergibt sowie die Möglichkeit, die Streifen nach vorausgegangener Benetzung besser zu entwässern.The invention has for its object a floor mopping device of the beginning mentioned type to develop in such a way that with a simplified Manufacture results in greater robustness and the possibility of It is better to dewater strips after wetting.

Diese Aufgabe wird erfindungsgemäß mit einem Bodenwischgerät der eingangs genannten Art gelöst, bei dem der Anschlag an der Hülse vorgesehen ist und eine sich quer zu der Achse erstreckende Basis hat. Der Anschlag bildet somit im Normalfall einen achsparallelen Vorsprung, der auf einer die Achse umschließenden, gedachten Kreisringfläche angeordnet ist. Dem Anschlag der Hülse ist zumindest ein Gegenanschlag am Schaft zugeordnet mit einer seiner Gestalt entsprechenden Form und Größe. Es ist auch möglich, den Anschlag und den Gegenanschlag bzw. die Teilanschläge und die Teilgegenanschläge völlig übereinstimmend auszubilden. Der Gegenanschlag bildet ein Bestandteil eines den Schaft umschließenden Ringes. Dieser ist axial verschiebbar auf dem Schaft gelagert und mit einer Feder an die Hülse anpreßbar, beispielsweise durch eine Feder, welche durch einen den Schaft umschließenden, federelastischen Schaumstoffring gebildet ist. This object is achieved according to the invention with a floor mopping device mentioned type solved, in which the stop provided on the sleeve and has a base extending across the axis. The stop forms thus normally an axially parallel projection that on a Axis surrounding, imaginary circular surface is arranged. The attack the sleeve is associated with at least one counter stop on the shaft a shape and size corresponding to its shape. It is also possible, the stop and the counter stop or the partial stops and the partial counter stops to train completely in accordance. The counter attack forms part of a ring surrounding the shaft. This is axially displaceable on the shaft and with a spring on the sleeve can be pressed, for example by a spring, which through a shaft enclosing, resilient foam ring is formed.

Bei der Herstellung eines ihn aufweisenden Formteils im Spritzgießverfahren besteht dadurch die Möglichkeit, Formwerkzeuge zu verwenden, die nur zwei Formhälften haben, wenn die Basis des Anschlags in der Trennebene angeordnet wird. Der unter Verwendung eines solchen Formwerkzeugs parallel zur Öffnungsrichtung vorstehende Anschlag kann bei Verwendung einer entsprechenden Herstellungsmethode nahezu beliebig groß dimensioniert und in eine nahezu beliebig große Anzahl von in Umfangsrichtung und/oder in radialer Richtung auf einander folgenden Teilanschlägen untergliedert sein, was es gestattet, die während der bestimmungsgemäßen Verwendung von dem Gegenanschlag darauf ausgeübten Reaktionskräfte so stark abzusenken, daß sich nahezu unabhängig von deren Größen eine verschleißfreie Benutzbarkeit der Freilaufeinrichtung ergibt. Hinsichtlich der Dauerhaftigkeit des Bodenwischgeräts ist das von großem Vorteil.In the manufacture of a molded part with an injection molding process This gives the possibility to use molds that only two Mold halves have when the base of the stopper is arranged in the parting plane becomes. The using such a mold parallel to Opening direction protruding stop can be used when using a corresponding Production method almost any size and in an almost arbitrarily large number of circumferentially and / or radially Direction on successive partial strokes, what it allows the use of the Counterstop on it exerted reaction forces so much that almost regardless of their sizes, wear-free usability of the Freewheel device results. Regarding the durability of the Floor mopping device is a great advantage.

Die flexiblen, saugfähigen Streifen können aus irgendeinem einschlägig vorbekannten Material bestehen, beispielsweise aus Fasersträngen, einem Textil- und / oder einem Schaumstoffmaterial. Sie sind im allgemeinen im wesentlichen gleichmäßig in Umfangsrichtung verteilt und werden durch Verlagerung der Hülse in Richtung des Endes des Schaftes schleifenförmig ausgelegt, mit Wasser benetzt und zur Durchführung von Reinigungsvorgängen verwendet. Im Anschluß an die Schmutzaufnahme werden die Streifen in Wasser ausgespült und durch Relativverschiebung der Hülse auf dem Schaft in eine mehr oder weniger gestreckte Lage überführt. Beim Erreichen der diesbezüglichen Position gelangt die Hülse in Eingriff mit den an dem Schaft festgelegten, abschaltbaren Mitteln, die sie im Bereich einer dem Ende zugewandten, ringförmigen Fläche untergreifen und verhindern, daß sich die Hülse ohne weiteres in Richtung des Endes zurückbewegen kann. Der Benutzer ist dadurch in die Lage versetzt, durch eine Relatiwerdrehung der Hülse, bezogen auf den Schaft, in den Streifen eine Zugspannung zu erzeugen und die Streifen auf diese Weise zu entwässern. Die Aufbringung axial gerichteter Haltekräfte ist dabei nicht nötig. Für die praktische Handhabung des Bodenwischgerätes ist das von großem Vorteil.The flexible, absorbent strips can be made from any relevant previously known material consist, for example, of fiber strands, a Textile and / or a foam material. They are generally in distributed substantially evenly in the circumferential direction and are by Displacement of the sleeve in the direction of the end of the shaft in a loop designed, wetted with water and to carry out cleaning processes used. Following the dirt pick-up the strips are rinsed out in water and by relative displacement the sleeve on the shaft in a more or less extended position transferred. When the relevant position is reached, the sleeve arrives in engagement with the switchable means fixed on the shaft, the it in the area of an annular surface facing the end reach under and prevent the sleeve from easily moving in the direction can finally move back. This enables the user offset by a relative rotation of the sleeve in relation to the shaft, to create tension in the strips and the strips on them Way to drain. The application of axially directed holding forces is not necessary. For the practical handling of the floor mopping device it’s a big advantage.

Als zweckmäßig hat es sich erwiesen, wenn die Mittel einen Bestandteil einer an dem Schaft festgelegten, in Richtung des Endes offenen Glocke bilden, die zugleich die Freilaufeinrichtung radial außenseitig umschließt. Verletzungsgefahren wird hierdurch vorgebeugt und ein gutes Erscheinungsbild erreicht.It has proven to be expedient if the means are a component a bell attached to the shaft and open towards the end form, which at the same time encloses the freewheel device radially on the outside. This prevents the risk of injury and a good appearance reached.

Die Mittel können durch eine Feder dauerwirksam sein, beispielsweise durch eine Blatt- oder Schraubenfeder, die mit den Mitteln zusammenwirkt. Sie sind zweckmäßig durch eine Betätigungstaste leicht abschaltbar gestaltet. The means can be permanently effective by means of a spring, for example by a leaf or coil spring that interacts with the means. They are expediently easily switched off using an actuation button designed.

Die ringförmige Fläche kann einen radial nach außen weisenden Vorsprung der Hülse in Richtung des Endes des Schaftes begrenzen. Im Allgemeinen ist der Vorsprung ringförmig gestaltet und am Ende der Hülse angeordnet. Die Menge des zur Herstellung der Hülse benötigten Werkstoffes läßt sich dadurch deutlich reduzieren, ohne daß Nachteile hinsichtlich der Robustheit oder Griffigkeit der Hülse in Kauf genommen werden müßten.The annular surface can have a radially outward projection limit the sleeve towards the end of the shaft. in the Generally the projection is annular and at the end of the sleeve arranged. The amount of material needed to make the sleeve can be significantly reduced without disadvantages in terms of the robustness or grip of the sleeve are accepted would.

Der Anschlag kann in Wirkungsrichtung, d.h. in der Richtung, in der er während der bestimmungsgemäßen Verwendung an dem Gegenanschlag anliegt, durch eine Anschlagsfläche begrenzt sein, die einen Bestandteil einer in der Achse des Schafts errichteten, gedachten Ebene bildet. Die bei einer Relativverdrehung der Hülse von dem Gegenanschlag auf den Anschlag ausgeübten Kräfte werden bei einer solchen Ausbildung senkrecht eingeleitet, was ein gegenseitiges Verklemmen beider Flächen ausschließt und gewährleistet, daß die Flächen im Anschluß an einen vorausgegangenen Entwässerungsprozeß besonders leichtgängig voneinander gelöst werden können.The stop can be in the direction of action, i.e. in the direction in which he during the intended use on the counter stop abuts, be limited by a stop surface, which is a component an imaginary plane built in the axis of the shaft. The in the event of a relative rotation of the sleeve from the counterstop to the Forces trained in this way are subjected to stop forces initiated vertically, resulting in a mutual jamming of both surfaces excludes and ensures that the surfaces following one previous drainage process particularly smoothly can be separated from each other.

Entgegen der Wirkungsrichtung ist der Anschlag zweckmäßig durch eine die Achse umschließende Wendel- oder Schrägfläche begrenzt. Je kleiner der Neigungswinkel ist, den die Wendel- oder Schrägfläche mit der Achse einschließt, desto leichter läßt sich die Hülse relativ zu dem Schaft verdrehen. Dabei muß allerdings berücksichtigt werden, daß ein abnehmender Neigungswinkel zwangsläufig eine Verminderung der Größe der Anschlagsfläche zur Folge hat. Die Anwendung von Neigungswinkeln zwischen 5 und 35° wird aus diesem Grunde bevorzugt.Contrary to the direction of action, the stop is advisable by a limits the helical or inclined surface surrounding the axis. The smaller is the angle of inclination that the helical or inclined surface with the axis includes, the easier the sleeve can be rotated relative to the shaft. However, it must be taken into account that a decreasing Inclination angle inevitably reduces the size of the stop surface has the consequence. The application of angles of inclination between 5 and 35 ° is preferred for this reason.

Um eine Entwässerung der Streifen kraftsparend in besonders kleinen Schritten zu ermöglichen, hat es sich als vorteilhaft bewährt, wenn der Anschlag mehrere Teilanschläge umfaßt, die gleichmäßig in Umfangsrichtung verteilt sind. Diese können aufeinanderfolgend mit einem oder mit mehreren Gegenanschlägen in Eingriff gelangen. To drain the strips effortlessly in particularly small To enable steps, it has proven to be advantageous if the Stop includes several partial stops that are even in the circumferential direction are distributed. These can be consecutive with one or with engage several counter-stops.

The stops 9, the Counter stops 15, the ring 16 and the spring 17 are of one Plastic bell 13 enclosed, the immovable on the shaft 1st is fixed, in the present case using a riveted joint.

Durch die auf dem Schaft unverschiebbar festgelegte Glocke 13 sind zugleich die abschaltbaren Mittel 7 dem Schaft 1 unverrückbar zugeordnet, die eine dem Ende 6 des Schafts 1 zugewandte, ringförmige Fläche 8 der Hülse 3 untergreifen und durch einen radial nach außen bewegbaren Stift gebildet sind.By the bell 13 immovably fixed on the shaft at the same time the switchable means 7 are assigned to the shaft 1 immovably, an annular surface 8 of the end 6 of the shaft 1 facing Reach under the sleeve 3 and by means of a radially outwardly movable pin are formed.

Der Stift ist am unteren Ende durch eine Schrägfläche begrenzt, die Hülse am oberen Ende durch eine damit kompatible Kegelfläche. Beim Einführen der Hülse 3 in die Glocke 13 bedarf es daher keiner Betätigung der Taste 10. Die miteinander in Eingriff gelangenden Schrägflächen bewirken vielmehr automatisch eine radial auswärts gerichtete Relativverlagerung des Stiftes 7, bis der Vorsprung 12 den Stift passiert hat und der Stift 7 an dessen Unterseite einschnappt.The pin is delimited at the lower end by an inclined surface, the sleeve at the top by a compatible conical surface. When inserting the sleeve 3 in the bell 13, therefore, no operation of the button is required 10. Create the sloping surfaces that come into contact with each other rather, a radially outward relative displacement automatically the pin 7 until the projection 12 has passed the pin and the pin 7 on the bottom snaps into place.

Die Anordnungsposition der Glocke 13 auf dem Schaft 1 ist so gewählt, daß sich beim Erreichen der diesbezüglichen Position der Hülse 3 eine weitgehende Streckung der Streifen 5 ergibt. The position of the bell 13 on the shaft 1 is selected so that when reaching the relevant position of the sleeve 3 a Extensive stretching of the strips 5 results.

Im Anschluß daran wird eine Relativverdrehung der Hülse 3, bezogen auf die Glocke 13, im Sinne der in Figur 4 eingetragenen Pfeile bewirkt. Sie hat zugleich eine periodische Auf- und Abwärtsbewegung des Ringes 16 zur Folge, während die Anschläge 9 über die Spitzen der Gegenanschläge 15 hinweggleiten. Es ist offensichtlich, daß mit abnehmendem Steigungswinkel der Anschläge und der Gegenanschläge die Kraft kleiner wird, die für eine Verformung der Feder 17 nötig ist, daß aber eine zunehmende Verringerung des Steigungswinkels zugleich eine Verminderung der Größe der Anschlagflächen 9.1 bzw. 15.1 bedingt. Steigungswinkel zwischen 15 und 25° werden aus diesem Grunde bevorzugt.Subsequently, a relative rotation of the sleeve 3, based on the bell 13, in the sense of the arrows shown in Figure 4. she also has a periodic up and down movement of the ring 16 result, while the stops 9 over the tips of the counter-stops 15 slide away. It is obvious that as the slope angle decreases the stops and counterstops the force becomes smaller is necessary for a deformation of the spring 17, but that an increasing Reducing the pitch angle also reduces the size of the stop surfaces 9.1 or 15.1. Pitch angle between 15 and 25 ° are preferred for this reason.

Durch eine Relativverdrehung der Hülse 3, bezogen auf den Schaft 1, läßt sich somit eine Streckung und Entwässerung der Streifen 5 bewirken, ohne daß es der Ausübung axial gerichteter Haltekräfte auf die Hülse 3 bedarf. Beim Erreichen eines hinreichend trockenen Zustandes der Streifen 5 kann daher die Hülse 3 durch die Betätigungstaste 10 von der Freilaufeinrichtung 4 gelöst werden mit der Folge, daß die Hülse 3 auf dem Schaft 1 in Richtung es Endes 6 abwärts gleitet und die Streifen 5 in eine für einen Wischprozeß geeignete Form überführt werden.By a relative rotation of the sleeve 3, based on the shaft 1, can stretching and dewatering of the strips 5 thus result, without exerting axially directed holding forces on the sleeve 3 requirement. When a sufficiently dry state of the Strip 5 can therefore the sleeve 3 by the button 10 of the Freewheel device 4 are solved with the result that the sleeve 3 on the Shaft 1 slides down towards end 6 and strips 5 into one suitable form for a wiping process are transferred.
