Description

Die vorliegende Erfindung betrifft einen Handreiniger zur Reinigung glatter Flächen, insbesondere Fensterscheiben, mit den Merkmalen des Anspruchs 1.The present invention relates to a hand cleaner for cleaning smooth surfaces, in particular window panes, with the features of claim 1.

Handreiniger der in der Rede stehenden Art sind aus dem Stand der Technik hinlänglich bekannt. Sie basieren allgemein auf dem Ansatz, ein Wischerblatt aus elastischem Material gegen z. B. eine Scheibe zu pressen und anschließend entlang der Scheibe zu bewegen. Das Wischerblatt zieht dabei an der Scheibe befindliche Flüssigkeiten in Bewegungsrichtung ab. Dabei tritt besonders bei vertikal ausgerichteten Scheiben das Problem auf, dass die abgezogene Flüssigkeit bei Erreichen einer bestimmten Menge am Wischerblatt unkontrolliert am Handreiniger entlang oder seitlich an diesem vorbei fließt. Die alternative Verwendung eines Reinigungsgerätes aus saugfähigem Material vermeidet zwar den Effekt des unkontrollierten Abfließens der von der glatten Fläche zu entfernenden Flüssigkeit, erzielt aber bei weitem nicht die hohe Reinigungsgüte und -geschwindigkeit eines Reinigungsgerätes mit Wischerblatt.Hand cleaner of the type in question are well known in the art. They are generally based on the approach, a wiper blade made of elastic material against z. B. to press a disk and then move along the disk. The wiper blade pulls off liquids located on the disc in the direction of movement. In this case, the problem occurs particularly with vertically aligned slices that the withdrawn liquid on reaching a certain amount on the wiper blade flows uncontrollably along the hand cleaner or laterally past it. Although the alternative use of a cleaning device of absorbent material avoids the effect of the uncontrolled flow of liquid to be removed from the smooth surface, but achieved by far not the high cleaning quality and speed of a cleaning device with wiper blade.

Die DE 20 117 528 U1 betrifft ein Handreinigungsgerät zum Reinigen glatter Flächen, insbesondere Glas- und Fensterscheiben, mit einer wasserabführenden Wischleiste und einer parallel zur Wischleiste verlaufenden Wasserauffangrinne, wobei ein saufähiges Material vorgesehen ist, um das von der Wischleiste abgezogene Wasser aufzufangen.The DE 20 117 528 U1 relates to a hand cleaning device for cleaning smooth surfaces, in particular glass and window panes, with a water-removing wiper strip and a parallel to the wiper strip water collecting channel, wherein a saufähiges material is provided to absorb the withdrawn from the wiper strip water.

Die EP 1 287 777 A2 betrifft ein Gerät zum Reinigen glatter Flächen, aufweisend eine gummielastische Wischlippe und einen Halter, wobei der Halter als Auffangbehälter ausgebildet ist; wobei Flüssigkeit von der Wischlippe über Elemente und Schlitzöffnungen in den Auffangbehälter, und dabei insbesondere zu einem im Auffangbehälter vorgesehenen saugfähigen Material gelangt.The EP 1 287 777 A2 relates to a device for cleaning smooth surfaces, comprising a rubber elastic wiper lip and a holder, wherein the holder is designed as a collecting container; wherein liquid from the wiper lip via elements and Slot openings in the collecting container, and in particular passes to a provided in the collecting container absorbent material.

Die WO 03/061 448 A1 beschreibt einen Abzieher mit einer Wischlippe, einem Wasserauffangbereich, welcher mit saugfähigem Material gefüllt ist und borstenähnlichen Elementen, welche dafür ausgelegt sind, Wasser, welches von der Wischlippe aufgefangen wird, in Richtung des saugfähigen Materials zu leiten.The WO 03/061 448 A1 describes a puller with a wiper lip, a water catchment area filled with absorbent material and bristle-like elements designed to direct water caught by the wiper lip towards the absorbent material.

Aufgabe der vorliegenden Erfindung ist es also, einen Handreiniger bereitzustellen, der die Vorteile eines Reinigers mit Wischerblatt aufweist, dabei aber das Problem der unkontrolliert abfließenden Flüssigkeit beim Reinigen einer glatten Fläche vermeidet.Object of the present invention is therefore to provide a hand cleaner, which has the advantages of a cleaner with wiper blade, while avoiding the problem of uncontrolled effluent liquid when cleaning a smooth surface.

Diese Aufgabe wird gelöst mit einem Handreiniger mit den Merkmalen des Anspruchs 1. Bevorzugte Ausführungsformen ergeben sich aus den abhängigen Ansprüchen Erfindungsgemäß umfasst der Handreiniger, insbesondere Handreiniger für glatte Flächen, eine Trägereinheit, ein Wischerblatt, eine Leitvorrichtung und eine Auffangeinheit, wobei das Wscherblatt an der Trägereinheit festgelegt ist, wobei das Wischerblatt zumindest bereichweise ein Führungselement aufweist, welches ausgelegt ist, ein am Wischerblatt befindliches Fluid in Richtung der Leitvorrichtung zu leiten, und wobei die Leitvorrichtung benachbart zum Wischerblatt angeordnet ist und an die Auffangeinheit grenzt, um das Fluid vom Wischerblatt über das Führungselement und die Leitvorrichtung hin zur Auffangeinheit zu transportieren. Das Wischerblatt, welches erfindungsgemäß an der Trägereinheit festgelegt ist, wird während des Reinigungsvorgangs gegen die zu reinigende, glatte Oberfläche gepresst, wobei ein von dieser Oberfläche zu entfernendes Fluid auf das Wischerblatt übertreten kann. Eine glatte Fläche, bzw.

Dabei kann die glatte Fläche bevorzugt eben, wie beispielsweise eine Fensterscheibe, oder gewölbt sein, wie beispielsweise die Windschutzscheibe oder Karosserieteile eines Kraftfahrzeugs. Das der glatten Fläche anhaftende und von dieser zu entfernende Fluid setzt sich bevorzugt hauptsächlich aus den Komponenten Wasser, Reinigungsmittel und Schmutz zusammen. Bevorzugt wird das Wischerblatt entlang der glatten Fläche bewegt, wobei das Fluid im Kontaktbereich von Wischerblatt und Fläche aufgestaut wird.

A smooth surface or surface should preferably be characterized by a low surface roughness, for example window glass panes, polished or painted surfaces, or ceramic tiles in the context significant at this point. In this case, the smooth surface preferably flat, such as a window, or curved, such as the windshield or body parts of a motor vehicle. The fluid adhering to the smooth surface and to be removed therefrom preferably consists mainly of the components water, cleaning agent and dirt. Preferably, the wiper blade is moved along the smooth surface, wherein the fluid is dammed in the contact area of wiper blade and surface. This pent-up fluid should preferably be removed along the wiper blade, wherein the smooth surface is preferably free of fluid already after one passage of the wiper blade. Via the wiper blade, the fluid enters the guide device, which is arranged adjacent to one of its sides and / or at least partially opposite the wiper blade, and adjoins a collecting unit. Preferably, the guide device has geometric features, such as edges and / or paragraphs, which favor a flow of fluid from the wiper blade. The wiper blade has to support the line of the fluid to the guide element, which preferably prevents fluid from the wiper blade at a side other than the guide towards escape. Preferably, the wiper blade has two or a plurality of guide elements. In a preferred Embodiment is the guide element, or are the guide elements, designed in one piece with the wiper blade. In further advantageous embodiments, projections and / or recesses may be provided both on the wiper blade and on the guide elements, which engage in respective corresponding projections and / or recesses of the respectively opposite element and thus connect the guide element and wiper blade in a positive or non-positive manner.

In einer bevorzugten Ausführungsform ist ein erstes Ende des Wischerblattes an der Trägereinheit festgelegt, wobei ein zweites Ende vorgesehen ist, das dem ersten Ende gegenüber liegt, wobei der Abstand der beiden Enden voneinander die Längserstreckung des Wischerblattes ist, und wobei am zweiten Ende des Wischerblattes eine Querlippe vorgesehen ist, die quer zur Längserstreckung und im Wesentlichen parallel zur Kante des zweiten Endes von dem Wischerblatt absteht. Die Trägereinheit dient bevorzugt dazu, das Wischerblatt zu halten und entlang der glatten Fläche zu führen. Die Lagerung des Wischerblattes sichert dieses bevorzugt gegen Verdrehung und Verlagerung relativ zur Trägereinheit, sodass Kräfte und Momente von der Trägereinheit auf das Wischerblatt übertragen werden können. Es kann beispielsweise bevorzugt sein, eine Klemmvorrichtung an der Trägereinheit vorzusehen, in welcher ein Ende des Wischerblattes festgelegt wird. In einer weiteren bevorzugten Ausführungsform kann die Trägereinheit einen Bereich mit einer Hinterschneidung aufweisen, in welche ein Bereich mit einem Vorsprung am Wischerblatt eingeschoben wird, und dieses anschließend gegen Verlagerung in der Einschieberichtung gesichert wird. Weiterhin können am Wischerblatt Rücksprünge oder Bohrungen vorgesehen sein, in welche geeignete Vorsprünge an der Trägereinheit einrasten und einen Form- oder Kraftschluss herstellen. Gegenüber dem ersten, festgelegten Ende des Wischerblattes ist ein zweites, bevorzugt distales, also loses, Ende vorgesehen. Das Wischerblatt kann dabei bevorzugt eine rechteckige Form aufweisen, wobei die Kanten der beiden Enden des Wischerblattes bevorzugt die gleiche Länge besitzen. Vorteilhaft kann es sein, wenn das Wischerblatt eine trapezförmige Geometrie aufweist, wobei bevorzugt das distale Ende des Wischerblattes eine längere Kante als das festgelegte Ende aufweist, um eine größere Fläche mit einem Durchgang von Fluid befreien zu können. Die Kanten des festgelegten und des distalen Endes sind bevorzugt parallel zueinander ausgerichtet. Der Abstand der beiden Enden voneinander wird als die Längserstreckung des Wischerblattes definiert. Besonders bevorzugt weist das Wischerblatt an seinem distalen Ende die Querlippe auf, die quer zur Längserstreckung und bevorzugt parallel zur Kante des distalen Endes vom Wischerblatt absteht. Die Querlippe weist bevorzugt eine geringere Dicke quer zu ihrer Erstreckung auf als das Wischerblatt. Ein Ende der Querlippe ist bevorzugt festgelegt am Wischerblatt; das diesem gegenüberliegende, lose, bzw. distale, Ende der Querlippe kann bevorzugt an der Scheibe zur Anlage gebracht werden. Die Querlippe kann vorteilhaft aus demselben Material wie das Wischerblatt hergestellt und mit diesem einstückig ausgeführt sein. Weiterhin bevorzugt ist die Querlippe an dem Wischerblatt durch Herstellen einer stoffschlüssigen Verbindung, mittels beispielsweise Kleben oder Schweißen, oder durch Herstellen einer formschlüssigen Verbindung, mittels geeigneter Vor- und Rücksprünge an Querlippe und Wischerblatt, festgelegt. Bevorzugt erstreckt sich die Querlippe auch in einer zweiten Richtung, ebenensymmetrisch zur von Längserstreckung und Kante des distalen Endes des Wischerblattes aufgespannten Ebene. Das Wischerblatt mit einer derartigen, sich in zwei Richtungen erstreckenden Querlippe, weist, vereinfacht betrachtet, einen T-förmigen Querschnitt auf. Die ebenensymmetrische Ausgestaltung der Querlippe kombiniert mit auf beiden Seiten der des Wischerblattes vorgesehenen, ebenfalls ebenensymmetrisch zueinander ausgerichteten Führungselementen erlaubt eine Verbesserung des Anpressdrucks der Querlippe auf die glatte Fläche. Insbesondere kann durch gezielte Materialstärkeverteilung der Führungselemente entlang der Längserstreckung die Biegesteifigkeit des Verbundes aus Wischerblatt und Führungselementen bevorzugt als veränderlich entlang der Längserstreckung des Wischerblattes ausgeführt werden, und auf diese Weise beispielsweise der Winkel zwischen Querlippe und glatter Fläche bei verschieden großer Anpressung des Handreinigers an die glatte Fläche in einem vorteilhaften Bereich gehalten werden. Mit der Bezeichnung "quer" kann in bevorzugten Ausführungsformen jeweils "senkrecht" angenommen werden.In a preferred embodiment, a first end of the wiper blade is secured to the support unit with a second end opposite the first end, the distance between the two ends being the longitudinal extent of the wiper blade, and at the second end of the wiper blade Transverse lip is provided which projects transversely to the longitudinal extent and substantially parallel to the edge of the second end of the wiper blade. The carrier unit preferably serves to hold the wiper blade and guide it along the smooth surface. The mounting of the wiper blade secures it preferably against rotation and displacement relative to the carrier unit, so that forces and moments can be transmitted from the carrier unit to the wiper blade. For example, it may be preferable to provide a clamping device on the carrier unit in which one end of the wiper blade is fixed. In a further preferred embodiment, the carrier unit can have a region with an undercut into which an area with a projection is inserted on the wiper blade, and this is subsequently secured against displacement in the insertion direction. Furthermore, recesses or bores may be provided on the wiper blade into which engage suitable projections on the carrier unit and produce a positive or frictional connection. Opposite the first, fixed end of the wiper blade, a second, preferably distal, that is loose, end is provided. The wiper blade may preferably have a rectangular shape, wherein the edges of the two ends of the wiper blade preferably have the same length. It can be advantageous if the wiper blade has a trapezoidal geometry, wherein preferably the distal end of the wiper blade has a longer edge than the fixed end in order to be able to liberate a larger area with a passage of fluid. The edges of the fixed and the distal end are preferably aligned parallel to each other. The distance between the two ends is defined as the longitudinal extent of the wiper blade. Particularly preferably, the wiper blade at its distal end on the transverse lip, which projects transversely to the longitudinal extent and preferably parallel to the edge of the distal end of the wiper blade. The transverse lip preferably has a smaller thickness transverse to its extension than the wiper blade. One end of the transverse lip is preferably fixed on the wiper blade; the opposing, loose, or distal, end of the transverse lip can be preferably brought to the disc to the plant. The cross-lip can advantageously be made of the same material as the wiper blade and designed in one piece with this. Further preferably, the transverse lip on the wiper blade by producing a material connection, by means of, for example gluing or welding, or by establishing a positive connection, by means of suitable projections and recesses on cross-lip and wiper blade, set. Preferably, the transverse lip also extends in a second direction, symmetrical to the plane defined by the longitudinal extent and edge of the distal end of the wiper blade plane. The wiper blade with such a cross-lip extending in two directions has, in simplified terms, a T-shaped cross-section. The plane symmetrical design of the transverse lip combined with provided on both sides of the wiper blade, also plane symmetrical aligned guide elements allows an improvement of the contact pressure of the transverse lip on the smooth surface. In particular, the bending stiffness of the composite of wiper blade and guide elements can preferably be designed as variable along the longitudinal extension of the wiper blade through targeted material thickness distribution of the guide elements along the longitudinal extent, and in this way, for example, the angle between the transverse lip and smooth surface at different pressures of the hand cleaner on the smooth Area can be kept in a favorable area. The term "transverse" may be assumed in preferred embodiments in each case "perpendicular".

In einer vorteilhaften Ausführungsform sind die Querlippe und/oder das Führungselement und/oder die Leitvorrichtung an der Seite des Wischerblattes, welche zur glatten Fläche hin weist, angeordnet. Um den Fluidleitvorgang von der Querlippe bis hin zur Auffangeinheit besonders zuverlässig zu gestalten, sind bevorzugt alle unterstützenden Elemente bzw. Vorrichtungen an der während des Reinigungsvorganges zur glatten Fläche hin weisenden Seite des Wischerblattes, oder an diese Seite angrenzend, vorgesehen. Es ist somit gewährleistet, dass über das distale Ende des Wischerblattes selbst, oder bevorzugt über die Querlippe, aufgenommenes Fluid unterstützt durch das Führungselement entlang des Wischerblattes fließen und zur Leitvorrichtung gelangen kann. Die Leitvorrichtung leitet das Fluid anschließend in die Auffangeinheit.In an advantageous embodiment, the transverse lip and / or the guide element and / or the guide device on the side of the wiper blade, which faces towards the smooth surface, arranged. In order to make the Fluidleitvorgang of the transverse lip to the collecting unit particularly reliable, are preferably all supporting elements or devices on the during the cleaning process to the smooth surface facing side of the wiper blade, or adjacent to this side provided. It is thus ensured that fluid received via the distal end of the wiper blade itself, or preferably via the transverse lip, flows through the guide element along the wiper blade and can reach the guide device. The guide device then directs the fluid into the collecting unit.

Bevorzugt erstreckt sich das Führungselement im Wesentlichen entlang der Längserstreckung. Mit anderen Worten weist das Führungselement eine Erstreckung auf, die entlang der Längserstreckung des Wischerblattes größer als und bevorzugt ein Vielfaches der Erstreckung in anderen Richtungen ist.Preferably, the guide element extends substantially along the longitudinal extent. In other words, the guide element has an extension which is greater than and preferably a multiple of the extent in other directions along the longitudinal extension of the wiper blade.

Bevorzugt steht das Führungselement in einem bestimmten Bereich mit geringerer Erstreckung als die Querlippe vom Wischerblatt ab, so dass bei Aufliegen des Wischerblattes auf der glatten Fläche die Querlippe nicht von der glatten Fläche abhebt. Da sich sowohl die Querlippe als auch das Führungselement vom Wischerblatt, bevorzugt in derselben Richtung, abstehend erstrecken, muss darauf geachtet werden, dass bei Verformung des Wischerblattes während des Reinigungsvorganges, die Querlippe nicht von der glatten Fläche abgehoben wird, bzw. sich der Anpressdruck der Querlippe auf die glatte Fläche nicht soweit verringert, dass abschnittsweise oder über die gesamte Länge der Querlippe ein Spalt zwischen der glatten Fläche und der Querlippe entsteht. Es ist daher bevorzugt, dass die Führungselemente in dem Bereich mit der Länge x eine geringere Erstreckung quer zur Längserstreckung des Wischerblattes besitzen als die Querlippe. Darüber hinaus kann es von Vorteil sein, dass zwischen dem festgelegten Ende des Wischerblattes und etwa der Hälfte von dessen Längserstreckung die Führungselemente nur um etwa 1 mm vom Wischerblatt abstehen, wobei insbesondere bei sehr starker Anpressung des Handreinigers an die glatte Fläche weiterhin ein optimales Anliegen der Querlippe an der glatten Fläche gewährleistet ist.Preferably, the guide element is in a certain area with a lesser extent than the transverse lip of the wiper blade, so that when resting the wiper blade on the smooth surface, the cross lip does not lift off the smooth surface. Since both the transverse lip and the guide element extend away from the wiper blade, preferably in the same direction, care must be taken that during deformation of the wiper blade during the cleaning process, the transverse lip is not lifted off the smooth surface, or the contact pressure of Cross-lip on the smooth surface is not reduced so far that in sections or over the entire length of the transverse lip, a gap between the smooth surface and the transverse lip is formed. It is therefore preferred that the guide elements in the region with the length x have a smaller extension transversely to the longitudinal extent of the wiper blade than the transverse lip. In addition, it may be advantageous that between the fixed end of the wiper blade and about half of its longitudinal extension, the guide elements protrude only by about 1 mm from the wiper blade, in particular in very strong Pressing the hand cleaner on the smooth surface continues to ensure optimum concern of the transverse lip on the smooth surface.

Vorteilhafterweise liegt das Verhältnis des Bereiches x zur gesamten Längserstreckung des Wischerblattes zwischen 0,2 und 0,9, bevorzugt zwischen 0,3 und 0,6 und besonders bevorzugt bei 0,4.Advantageously, the ratio of the region x to the total longitudinal extension of the wiper blade is between 0.2 and 0.9, preferably between 0.3 and 0.6, and particularly preferably at 0.4.

In einer ferner bevorzugten Ausführungsform beträgt die Längserstreckung des Wischerblattes ein Vielfaches der Dicke des Wischerblattes, wobei das Verhältnis der Längserstreckung zur Dicke bevorzugt größer als 10, besonders bevorzugt 15 und insbesondere bevorzugt etwa 17 ist. Bevorzugt ist das elastisch verformbare, bzw. rückstellfähige, Material, aus welchem das Wischerblatt hergestellt ist, ein Siloxan, wobei die Querlippe durch die Rückstellkraft einer elastischen Verformung des Wischerblattes auf die glatte Fläche gedrückt wird. Die verhältnismäßig große Längserstreckung des Wischerblattes hat den vorteilhaften Effekt, dass bei unterschiedlicher Durchbiegung des gesamten Wischerblattes die Querlippe mit relativ gleichmäßiger Kraft auf die glatte Fläche gepresst wird. Durch die Verwendung des besonders zur elastischen Verformung geeigneten Herstellungsmaterials wirken sich Winkeländerungen am festgelegten Ende des Wischerblattes nicht unmittelbar auf die Querlippe, bzw. deren Lage an der glatten Fläche, aus. Die große Längserstreckung des Wischerblattes bietet darüber hinaus die Möglichkeit, bei einer bevorzugten trapezförmigen Geometrie des Wischerblattes ein distales Ende des Wischerblattes vorzusehen, dessen Kante erheblich länger ist als die des festgelegten Endes, ohne dabei eine zu starke Umlenkung der Fluidströmung entlang des Wischerblattes und drohendes seitliches Entweichen des Fluids zu riskieren. Die große Längserstreckung des Wischerblattes gibt bei dieser bevorzugten Ausführungsform die Möglichkeit, die Fluidströmung entlang des Wischerblattes allmählich von der großen Erstreckung an der Querlippe, bzw. dem distalen Ende, bis hin zur kleineren Erstreckung vor der Leitvorrichtung zu verengen. Als Vorzug des Materials Siloxan zur Herstellung des Wischerblattes sei an dieser Stelle noch die Schmierwirkung dieses Materials angeführt, welche ein verbessertes Gleiten des Wischerblattes über die zu reinigende Fläche und damit einen reduzierten Kraftaufwand beim Bedienen des Handreinigers zur Folge hat.In a further preferred embodiment, the longitudinal extension of the wiper blade is a multiple of the thickness of the wiper blade, wherein the ratio of the longitudinal extent to the thickness is preferably greater than 10, more preferably 15 and particularly preferably about 17. Preferably, the elastically deformable, or resilient, material from which the wiper blade is made, a siloxane, wherein the transverse lip is pressed by the restoring force of an elastic deformation of the wiper blade on the smooth surface. The relatively large longitudinal extent of the wiper blade has the advantageous effect that at different deflection of the entire wiper blade, the cross-lip is pressed with relatively uniform force on the smooth surface. By using the production material which is particularly suitable for elastic deformation, angular changes at the fixed end of the wiper blade do not directly affect the transverse lip or its position on the smooth surface. The large longitudinal extent of the wiper blade also offers the possibility, in a preferred trapezoidal geometry of the wiper blade to provide a distal end of the wiper blade whose edge is considerably longer than that of the fixed end, without causing excessive deflection of the fluid flow along the wiper blade and threatening lateral Venting the fluid to escape. The large longitudinal extension of the wiper blade in this preferred embodiment provides the ability to gradually narrow the fluid flow along the wiper blade from the large extent at the cross-lip, or distal end, to the smaller extent before the guide. As a preference of the material siloxane for the production of the wiper blade, the lubricating effect of this material is given at this point, which has an improved sliding of the wiper blade on the surface to be cleaned and thus a reduced effort when operating the hand cleaner result.

Mit Vorteil ist an der Auffangeinheit oder der Trägereinheit eine Auslassöffnung vorgesehen, wobei die Auslassöffnung vorzugsweise verschließbar ist. Damit das über die Leitvorrichtung in die Auffangeinheit gelangende Fluid bequem aus der Auffangeinheit ausgelassen werden kann, ist bevorzugt eine oder eine Vielzahl von Auslassöffnungen, z. B. in Form von Bohrungen, in der Auffangeinheit vorgesehen. Besonders bevorzugt ist die Auslassöffnung dicht verschließbar, beispielsweise mittels eines Schraubverschlusses und einer geeigneten Dichtung. Es kann darüber hinaus bevorzugt sein, dass die Auffangeinheit mit einer Vorrichtung ausgestattet ist, die verhindert, dass Fluid in Richtung des Wischerblattes entweichen kann. Bevorzugt ist dies beispielsweise eine als Klappe angeordnete Kunststoffschicht, die das Hereintreten in die Auffangeinheit ermöglicht, in der Gegenrichtung jedoch schließt, so dass gewährleistet ist, dass das aufgefangene Fluid ausschließlich durch die Auslassöffnung aus der Auffangeinheit entweichen kann. Bei einer vorteilhaften Anordnung von mindestens zwei Auslassöffnungen an gegenüberliegenden Seiten der Auffangeinheit ergibt sich darüber hinaus auch die Möglichkeit, die Auffangeinheit durchzuspülen, um zum Beispiel Rückstände von Schmutz und Reinigungsmitteln aus dieser zu entfernen. Bevorzugt weist die Auffangeinheit eine Füllstandsanzeige auf, welche es ermöglicht, den Befüllungsgrad der Auffangeinheit von außen abzulesen.Advantageously, an outlet opening is provided on the collecting unit or the carrier unit, wherein the outlet opening is preferably closable. In order that the fluid passing into the collecting unit via the guide device can be conveniently discharged from the collecting unit, one or a plurality of outlet openings, eg. B. in the form of holes provided in the collecting unit. Particularly preferably, the outlet opening is tightly closed, for example by means of a screw cap and a suitable seal. It may moreover be preferred that the collecting unit is equipped with a device which prevents fluid from escaping in the direction of the wiper blade. This is preferred, for example, a plastic layer arranged as a flap, which allows entry into the collecting unit, but closes in the opposite direction, so that it is ensured that the collected fluid can escape from the collecting unit exclusively through the outlet opening. In an advantageous arrangement of at least two outlet openings on opposite sides of the collecting unit, moreover, it is also possible to flush through the collecting unit in order to remove, for example, residues of dirt and cleaning agents therefrom. Preferably, the collecting unit has a fill level indicator, which makes it possible to read the degree of filling of the collecting unit from the outside.

Insbesondere bevorzugt ist die Auslassöffnung derart angeordnet, dass sie sich, während der Handreiniger gegen die glatte Fläche gepresst wird, am höchsten Punkt eines von Auffangeinheit und Trägereinheit umschlossenen Sammelraumes befindet. Dieses Merkmal dient insbesondere dazu, den von der Auffangeinheit bzw. der Auffangeinheit und der Trägereinheit umschlossenen Sammelraum möglichst vollständig auszunutzen, bevor das aufgesammelte Fluid, bzw. die Flüssigkeit, durch die Auslassöffnung überläuft.Particularly preferably, the outlet opening is arranged in such a way that, while the hand cleaner is being pressed against the smooth surface, it is located at the highest point of a collecting space enclosed by the collecting unit and the carrier unit. This feature serves, in particular, to make the most complete use of the collecting space enclosed by the collecting unit or the collecting unit and the carrier unit, before the collected fluid, or the liquid, overflows through the outlet opening.

Bevorzugt sind die Trägereinheit und die Auffangeinheit unmittelbar aneinander grenzend angeordnet und mit Befestigungsmitteln verbunden. Bei dieser bevorzugten Ausführungsform ist die Auffangeinheit unmittelbar an der Trägereinheit gelagert, wobei eine besonders kompakte Bauweise des Handreinigers erreicht wird. Es kann bevorzugt sein, dass der Raum, in welchem sich das Fluid sammelt, an einer Seite durch die Trägereinheit begrenzt wird, wobei Trägereinheit und Auffangeinheit an ihrer Verbindungsstelle über eine entsprechende Dichtung verfügen müssen, die verhindert, dass Fluid an der Verbindungsstelle zwischen den beiden Elementen entweicht. Bevorzugt verbinden Befestigungsmittel die Auffang- und die Trägereinheit miteinander, wobei hierfür besonders bevorzugt Schrauben verwendet werden sollen, welche in dafür vorgesehene Bohrungen an Auffang- und Trägereinheit eingreifen. Bevorzugt können auch Vorsprünge und Rücksprünge an der Auffangeinheit und der Trägereinheit angeordnet sein, welche ineinander greifend einen Formschluss herstellen und auf diese Weise die Auffangeinheit und die Trägereinheit miteinander verbinden. Bevorzugt können die Träger- und die Auffangeinheit auch einstückig ausgeführt sein, z. B. hergestellt durch ein Druckgussverfahren, wobei der Montageaufwand zur Herstellung des Handreinigers vorteilhaft reduziert wird.Preferably, the carrier unit and the collecting unit are arranged directly adjacent to each other and connected with fastening means. In this preferred embodiment, the collecting unit is mounted directly on the carrier unit, wherein a particularly compact design of the hand cleaner is achieved. It may be preferred that the space in which the fluid collects is bounded on one side by the carrier unit, wherein carrier unit and collecting unit must have at their junction via a corresponding seal which prevents fluid escaping at the junction between the two elements. Preferably, fastening means connect the collecting and the carrier unit with each other, for this purpose, screws are particularly preferred to be used, which engage in holes provided for receiving and carrier unit. Preferably, projections and recesses may be arranged on the collecting unit and the carrier unit, which interlocking produce a form fit and connect in this way the collecting unit and the carrier unit together. Preferably, the carrier and the collecting unit can also be made in one piece, for. B. produced by a die-casting method, wherein the assembly effort for the preparation of the hand cleaner is advantageously reduced.

Es kann weiterhin alternativ bevorzugt sein, dass am Wischerblatt befindliches Fluid über eine verlängerte Leitvorrichtung in die Auffangeinheit gelangt, wobei die Auffangeinheit nicht unmittelbar an die Trägereinheit angrenzend angeordnet ist. In dieser bevorzugten Ausführungsform kann die Auffangeinheit als separate Baugruppe ausgelegt sein, beispielsweise ein Tank, den der Anwender des Handreinigers auf dem Rücken trägt bzw. der abstellbar ist. Dieser externe Auffangbehälter kann bevorzugt eine große Menge Fluid aufnehmen, ohne dass die Gewichtszunahme des Handreinigers den Anwender dabei behindert. Der erfindungsgemäße Handreiniger eignet sich in dieser bevorzugten Ausführungsform besonders gut für die Reinigung großer, mit einer großen Fluidmenge benetzter Oberflächen. Damit das Fluid in die Auffangeinheit gelangen kann, ist eine verlängerte Leitvorrichtung erforderlich. Diese verlängerte Leitvorrichtung weist vorzugsweise einen Abschnitt auf, zum Beispiel einen Schlauch, durch welchen das Fluid in eine von der Trägereinheit und dem Wischerblatt beabstandete Auffangeinheit fließen kann. Bevorzugt ist diese verlängerte Leitvorrichtung zumindest abschnittsweise in einen fest an der Trägereinheit zu lagernden Handgriff integriert.Alternatively, it may alternatively be preferred that fluid located on the wiper blade reaches the collecting unit via an extended guide device, wherein the collecting unit is not arranged directly adjacent to the carrier unit. In this preferred embodiment, the collecting unit can be designed as a separate module, for example a tank, which the user of the hand cleaner carries on his back or who can be parked. This external receptacle can preferably accommodate a large amount of fluid without the weight increase of the hand cleaner hinders the user. The hand cleaner according to the invention is particularly suitable in this preferred embodiment for the cleaning of large, wetted with a large amount of fluid surfaces. In order for the fluid to get into the collecting unit, an extended guiding device is required. This extended guide device preferably has a section, for example a hose, through which the fluid can flow into a collecting unit spaced from the carrier unit and the wiper blade. Preferably, this elongated guide device is at least partially integrated into a fixed to the support unit to be stored handle.

Bevorzugt ist an der Trägereinheit eine Handgriffhalterung vorgesehen, an welcher ein Handgriff gegen Verlagerung relativ zur Trägereinheit sicherbar ist. Der Handgriff dient in erster Linie dem Führen der Trägereinheit und damit auch des, mit dieser fest verbundenen, Wischerblattes entlang der glatten Oberfläche. Die Handgriffhalterung ist dabei bevorzugt einstückig mit der Trägereinheit hergestellt und weist vorzugsweise ein Gewinde auf, in welches ein an Haltegriff vorgesehenes Gewinde eingreift.Preferably, a handle holder is provided on the carrier unit, on which a handle against displacement relative to the carrier unit can be secured. Of the Handle is used primarily to guide the carrier unit and thus also, with this firmly connected wiper blade along the smooth surface. The handle holder is preferably made in one piece with the carrier unit and preferably has a thread, in which engages a thread provided on the handle.

Vorteilhafterweise ist ein Haltebügel schwenkbar an der Trägereinheit oder an der Auffangeinheit festlegbar, um das Wischerblatt bei einer bestimmten Auslenkung relativ zur Trägereinheit gegen die glatte Fläche gepresst zu halten. Insbesondere um ein leicht verformbares Wischerblatt, dessen Herstellungsmaterial einen geringen E-Modul aufweist, trotzdem mit großer Kraft gegen die glatte Fläche pressen zu können, ist ein Haltebügel vorgesehen. Dieser ist bevorzugt schwenkbar angeordnet, wobei ein oder bevorzugt zwei Anschlagstifte seine Schwenkbewegung in einer Schwenkrichtung begrenzen. Bei Erreichen dieser Schwenkposition begrenzt der Haltebügel wiederum eine Auslenkung des Wischerblattes, welches vorzugsweise in einem Aufnahmebereich des Haltebügels anschlägt. Bei Erhöhen der Anpresskraft des Anwenders auf den Handreiniger wird das Wischerblatt nun zusätzlich zu seiner Rückstellkraft auch durch die Rückstellkraft des Haltebügels gegen die glatte Fläche gepresst. Bevorzugt weist das Herstellungsmaterial einen hohen E-Modul auf, um bei geringer weiterer Verformung große Kräfte auf das distale Ende des Wischerblattes oder dessen Querlippe übertragen zu können.Advantageously, a retaining clip is pivotally attachable to the carrier unit or to the collecting unit in order to keep the wiper blade pressed against the smooth surface at a certain deflection relative to the carrier unit. In particular, in order to be able to press against the smooth surface with a large force against an easily deformable wiper blade whose production material has a low modulus of elasticity, a headband is provided. This is preferably arranged pivotably, wherein one or preferably two stop pins limit its pivoting movement in a pivoting direction. Upon reaching this pivot position of the headband limits in turn a deflection of the wiper blade, which preferably abuts in a receiving area of the retaining clip. When increasing the contact pressure of the user on the hand cleaner, the wiper blade is now pressed in addition to its restoring force by the restoring force of the retaining bracket against the smooth surface. The production material preferably has a high modulus of elasticity in order to be able to transmit large forces to the distal end of the wiper blade or its transverse lip with little further deformation.

Der Haltebügel ist um einen Schwenkwinkel α schwenkbar, wobei der Anschlagstift vorgesehen ist, welcher die Schwenkbewegung des Haltebügels in einer Schwenkrichtung beschränkt, wobei der maximale Schwenkwinkel α zwischen 20° und 90°, vorzugsweise zwischen 30° und 70° und besonders bevorzugt bei etwa 40° bis 50° liegt. Je nach Länge, bzw. Längserstreckung des Wischerblattes kann es bevorzugt sein, nur bestimmte Schwenkwinkel und damit nur bestimmte Auslenkungen des Wischerblattes zuzulassen. Es hat sich gezeigt, dass die genannten Bereiche von möglichen maximalen Schwenkwinkeln eine besonders einfache Anpassung des Handreinigers an bestimmte Oberflächen, die Dicke und Längserstreckung des Wischerblattes und die gewünschte Handhaltung des Anwenders bei Abziehen einer glatten Fläche ermöglichen.The headband is pivotable about a pivot angle α, wherein the stop pin is provided which limits the pivotal movement of the retaining bracket in a pivoting direction, the maximum pivot angle α between 20 ° and 90 °, preferably between 30 ° and 70 ° and particularly preferably at about 40 ° to 50 °. Depending on the length or longitudinal extension of the wiper blade, it may be preferable to allow only certain pivoting angles and thus only certain deflections of the wiper blade. It has been found that the mentioned ranges of possible maximum pivoting angles enable a particularly simple adaptation of the hand cleaner to certain surfaces, the thickness and longitudinal extension of the wiper blade and the desired hand position of the user when removing a smooth surface.

Alternativ bevorzugt kann der Haltebügel auch nicht-schwenkbar an der Trägereinheit oder der Auffangeinheit festgelegt sein, wobei das Wischerblatt bei Erreichen einer bestimmten Auslenkung gegen den Aufnahmebereich des Haltebügels stößt und wie zuvor beschrieben von diesem gehalten bzw. gestützt wird. Bevorzugt ist in diesem Fall der Haltebügel mit einem gewünschten Schwenkwinkel relativ zur Ruhelage des Wischerblattes an der Trägereinheit oder der Auffangeinheit festgelegt.Alternatively, preferably, the headband can also be fixed non-pivotably on the carrier unit or the collecting unit, wherein the wiper blade abuts against the receiving area of the holding bracket upon reaching a certain deflection and is held or supported by the latter as described above. Preferably, in this case, the headband is fixed with a desired swivel angle relative to the rest position of the wiper blade on the carrier unit or the interceptor unit.

Der in Fig. 1 gezeigte Handreiniger umfasst in einer bevorzugten Ausführungsform eine Trägereinheit 5, ein Wischerblatt 3, eine Leitvorrichtung 7, eine Auffangeinheit 9, einen Handgriff 11 und eine Handgriffhalterung 12. Das Wischerblatt 3 weist vorzugsweise eine Querlippe 31 und zumindest ein Führungselement 32 auf, welche sich jeweils zu der Seite hin erstrecken, an der auch die Leitvorrichtung 7 an das Wischerblatt 3 angrenzend gelagert ist. In der Figur 1 ist das Wischerblatt 3 in verformter Stellung gezeigt, wobei die Querlippe 31 gegen eine glatte Oberfläche 1 gepresst wird. Bevorzugt ist die glatte Oberfläche 1, wie in Figur 1 angedeutet, die Oberfläche einer Glasscheibe, welche mit einem Fluid F benetzt ist. Durch Herabziehen des Handreinigers entlang der Glasscheibe 1 sammelt sich das Fluid F an der Querlippe 31 und fließt, durch die Adhäsionswirkung an der Oberfläche des Wischerblattes 3 haftend, an diesem entlang bis zur Leitvorrichtung 7. An der Leitvorrichtung 7 ist, wie in Figur 1 dargestellt, bevorzugt ein Vorsprung oder Absatz vorgesehen, an welchem das Fluid F vom Wischerblatt 3 getrennt wird und entlang der Leitvorrichtung 7 bis in die Auffangeinheit 9 fließt. Der Raum, in welchem sich das Fluid F schließlich sammelt, wird in der bevorzugten Ausführungsform sowohl durch die Trägereinheit 5 als auch durch die Auffangeinheit 9 gebildet. In weiteren bevorzugten, nicht in Figur 1 gezeigten Ausführungsformen kann die Auffangeinheit 9 auch ein in sich geschlossener Hohlkörper sein, der beispielsweise direkt an der Trägereinheit 5 befestigt ist. Das Wischerblatt 3 ist in der bevorzugten Ausführungsform mittels einer formschlüssigen Verbindung an der Trägereinheit 5 festgelegt, wobei die Aussparung an der Trägereinheit 5 eine Hinterschneidung aufweist, in welche ein Vorsprung am Wischerblatt 3 formschlüssig eingereift und so das Wischerblatt 3 gegen Verlagerung und Verdrehung relativ zur Trägereinheit 5 sichert. An der Trägereinheit 5 ist darüber hinaus die Handgriffhalterung 12 vorgesehen, an welcher der Handgriff 11 festlegbar ist.The in Fig. 1 Hand cleaner shown in a preferred embodiment comprises a support unit 5, a wiper blade 3, a guide device 7, a collecting unit 9, a handle 11 and a handle holder 12. The wiper blade 3 preferably has a transverse lip 31 and at least one guide element 32, which in each case extend the side, at the also the guide device. 7 is mounted adjacent to the wiper blade 3. In the FIG. 1 the wiper blade 3 is shown in a deformed position, wherein the transverse lip 31 is pressed against a smooth surface 1. Preferably, the smooth surface 1 is as in FIG. 1 indicated, the surface of a glass sheet, which is wetted with a fluid F. By pulling down the hand cleaner along the glass pane 1, the fluid F collects at the transverse lip 31 and, adhering to the surface of the wiper blade 3 by the adhesion, flows along the latter to the guide device 7. At the guide device 7, as in FIG FIG. 1 illustrated, preferably provided a projection or shoulder, on which the fluid F is separated from the wiper blade 3 and along the guide device 7 flows into the collecting unit 9. The space in which the fluid F finally collects is formed in the preferred embodiment both by the carrier unit 5 and by the collecting unit 9. In further preferred, not in FIG. 1 In embodiments shown, the collecting unit 9 may also be a self-contained hollow body, which is fastened directly to the carrier unit 5, for example. The wiper blade 3 is fixed in the preferred embodiment by means of a positive connection to the support unit 5, wherein the recess on the support unit 5 has an undercut, in which a projection on the wiper blade 3 positively engages and thus the wiper blade 3 against displacement and rotation relative to the carrier unit 5 secures. On the support unit 5, the handle holder 12 is also provided on which the handle 11 can be fixed.

Figur 2 zeigt eine Seitenansicht einer bevorzugten Ausführungsform des erfindungsgemäßen Handreinigers, wobei insbesondere ein Bereich x gekennzeichnet ist, in welchem das Führungselement 32 die Querlippe 31 nach in der Figur unten bevorzugt nicht überragt. Gezeigt ist auch eine Längserstreckung L des Wischerblattes 3, welche sich vom festgelegten Ende des Wischerblattes 3 bis hin zu seinem freien, bzw. losen oder distalen, Ende erstreckt. Weiterhin ist die bevorzugte Ausführungsform dargestellt, bei welcher sich die Querlippe 31 in zwei Richtungen, also in der Figur sowohl nach oben als auch nach unten, erstreckt. Die Dicke D des Wischblattes 3 ist bevorzugt um ein Vielfaches kleiner als die Längserstreckung L. Gut in Figur 2 erkennbar ist weiterhin die Auslegung der Trägereinheit 5 und der Auffangeinheit 9, die jeweils als halbschalenartige Bauteile ausgeführt und mit nicht gezeigten Befestigungsmitteln miteinander verbunden sind. In die Auffangeinheit 9 oder die Trägereinheit 5 ist eine Auslassöffnung 91 eingebracht, welche ein Entleeren des durch die Auffangeinheit 9, oder die Auffangeinheit 9 und die Trägereinheit 5, gebildeten Sammelraumes ermöglicht. Vorteilhaft ist es, wenn die Auslassöffnung 91 möglichst in der oberen Hälfte des Sammelraumes bzw. benachbart zum Befestigungsbereich des Wischerblatts 3 an der Trägereinheit 5 angeordnet ist. Insbesondere bevorzugt ist es, dass, wenn der Handreiniger im Einsatz ist und das Wischerblatt 3, wie in Figur 1 gezeigt, schräg nach oben vom Handreiniger weg ragt, die Auslassöffnung 91 nahe des höchsten Punkt des Sammelraumes angeordnet ist, um den Sammelraum bis zu einem Überlaufen, bzw. Auslaufen von Flüssigkeit durch die Auslassöffnung 91, bestmöglich auszunutzen und eine maximale Menge Flüssigkeit aufnehmen zu können. FIG. 2 shows a side view of a preferred embodiment of the hand cleaner according to the invention, wherein in particular a region x is marked, in which the guide member 32, the cross lip 31 preferably in the figure below does not surmount. Shown is also a longitudinal extent L of the wiper blade 3, which extends from the fixed end of the wiper blade 3 to its free, or loose or distal, end. Furthermore, the preferred embodiment is shown, in which the transverse lip 31 extends in two directions, ie in the figure, both upwards and downwards. The thickness D of the wiper blade 3 is preferably many times smaller than the longitudinal extension L. Gut in FIG. 2 The design of the carrier unit 5 and the collecting unit 9, which are each designed as half-shell-like components, is also recognizable and are connected to each other with fastening means, not shown. In the collecting unit 9 or the carrier unit 5, an outlet opening 91 is introduced, which allows emptying of the collection space formed by the collecting unit 9, or the collecting unit 9 and the carrier unit 5. It is advantageous if the outlet opening 91 is arranged as possible in the upper half of the collecting space or adjacent to the fastening region of the wiper blade 3 on the carrier unit 5. It is particularly preferred that when the hand cleaner is in use and the wiper blade 3, as in FIG. 1 shown, obliquely upward from the hand cleaner protrudes, the outlet opening 91 is disposed near the highest point of the plenum so as to make the best possible use of the plenum to overflow or leakage of liquid through the outlet opening 91 and to be able to absorb a maximum amount of liquid ,

In den Figuren 3 bis 5 sind Ansichten bevorzugter Ausführungsformen des Führungselements 32 gezeigt. Dabei sind bevorzugt jeweils zwei oder mehr Führungselemente 32 an der Unterseite des Wischerblattes 3 angeordnet, wobei diese die Leitung des Fluids F von der Querlippe 31 hin zur Trägereinheit 5, bzw. der nicht gezeigten Leitvorrichtung 7, unterstützen. Bei der in Fig. 4 gezeigten Ausführungsform fungieren die Führungselemente 32 jeweils als das Wischerblatt 3 begrenzende Stege, die sich entlang der Seitenkante des Wischerblattes 3 erstrecken. Die in Figur 5 gezeigte, bevorzugte Variante der Führungselemente 32 ermöglicht ein Verringern der vom Fluid F am Wischerblatt 3 benetzten Breite, so dass die Leitvorrichtung 7 schmaler als das Wischerblatt 3 ausgelegt sein kann. Ähnlich dem Verlauf der Führungselemente 32 der Figur 5 können in einer nicht gezeigten Ausführungsform die Seitenkanten des Wischerblattes 3 vorgesehen sein, wobei das lose Ende mit der Querlippe 31 eine größere Kantenlänge besitzt als das an der Trägereinheit 5 festgelegte Ende.In the FIGS. 3 to 5 Views of preferred embodiments of the guide element 32 are shown. In this case, two or more guide elements 32 are preferably arranged on the underside of the wiper blade 3, wherein they support the conduction of the fluid F from the transverse lip 31 to the carrier unit 5, or the guide device 7, not shown. At the in Fig. 4 In the embodiment shown, the guide elements 32 each act as webs delimiting the wiper blade 3 and extending along the side edge of the wiper blade 3. In the FIG. 5 As shown, the preferred variant of the guide elements 32 makes it possible to reduce the width wetted by the fluid F on the wiper blade 3, so that the guide device 7 can be designed to be narrower than the wiper blade 3. Similar to the course of the guide elements 32 of the FIG. 5 can be provided in an embodiment, not shown, the side edges of the wiper blade 3, wherein the loose end with the transverse lip 31 has a greater edge length than the fixed to the support unit 5 end.

Figur 6 zeigt eine Ausführungsform, in welcher der Handreiniger zusätzlich zu den in Figuren 1 bis 5 gezeigten Merkmalen noch einen Haltebügel 8 aufweist. Der Haltebügel 8 ist bevorzugt über einen Schwenkbolzen 82 schwenkbar an der Trägereinheit 5 oder der Auffangeinheit 9 festgelegt, wobei ein Anschlagstift 84 vorgesehen ist, welcher die Schwenkbewegung des Haltebügels 8 in einer Richtung beschränkt. In einer ersten Position, auch als Ruhelage des Haltebügels 8 zu bezeichnen und in Figur 6 mit durchgezogener Linie dargestellt, ist der Haltebügel 8 parallel zum nicht verbogenen Wischerblatt 3 angeordnet oder liegt (nicht dargestellt) leicht auf diesem auf. Wird das Wischerblatt 3 an die glatte Fläche 1 gepresst, so verformt es sich und schwenkt dabei den Haltebügel 8 um einen Schwenkwinkel α, wie in der Figur gestrichelt dargestellt. Diese Schwenkbewegung ist nur bis zu einem Schwenkwinkel αmax möglich, bei welchem der Haltebügel 8 gegen den Anschlagstift 84 anschlägt. Wird bei Erreichen dieses maximalen Schwenkwinkels die Anpresskraft auf den Handreiniger weiter erhöht, so nimmt nun der Haltebügel 8 diese zusätzliche Kraft auf und presst das distale Ende des Wischerblattes 3 oder die Querlippe 31 mit dieser zusätzlichen Kraft gegen die glatte Fläche 1. Vorteilhafterweise kann mittels des Haltebügels 8 auf diese Weise ein höherer Anpressdruck erreicht werden, als dies allein durch die Rückstellkraft des elastisch verformten Wischerblattes 3 möglich ist. Um diesen Effekt zu begünstigen, ist der Haltebügel 8 vorzugsweise aus einem relativ steifen Material, wie Metall oder Duroplast, hergestellt. Bevorzugt ist der Anschlagstift 84 hohlkörperförmig ausgebildet, und konzentrisch bzw. koaxial zur Auslassöffnung 91 angeordnet, wobei durch die Auslassöffnung 91 fließende Flüssigkeit durch den Anschlagstift 84 fließt und ins Freie gelangt. FIG. 6 shows an embodiment in which the hand cleaner in addition to the in FIGS. 1 to 5 features shown still has a headband 8. The mounting bracket 8 is preferably fixed via a pivot pin 82 pivotally mounted on the support unit 5 or the collecting unit 9, wherein a stop pin 84 is provided which the pivotal movement of the retaining clip 8 in one direction limited. In a first position, also referred to as the rest position of the retaining clip 8 and in FIG. 6 shown by a solid line, the headband 8 is arranged parallel to the non-bent wiper blade 3 or is (not shown) easily on this. If the wiper blade 3 is pressed against the smooth surface 1, then it deforms and pivots the retaining bracket 8 by a swivel angle α, as shown by dashed lines in the figure. This pivoting movement is possible only up to a pivoting angle α max , in which the headband 8 abuts against the stopper pin 84. If the contact force on the hand cleaner is further increased when this maximum pivot angle is reached, the retaining clip 8 now absorbs this additional force and presses the distal end of the wiper blade 3 or the transverse lip 31 against the smooth surface 1 with this additional force Holding bracket 8 can be achieved in this way a higher contact pressure, as this is possible only by the restoring force of the elastically deformed wiper blade 3. To favor this effect, the headband 8 is preferably made of a relatively stiff material, such as metal or thermosetting plastic. Preferably, the stopper pin 84 is formed hollow body-shaped, and arranged concentrically or coaxially to the outlet opening 91, wherein flowing through the outlet opening 91 fluid flows through the stopper pin 84 and passes into the open.

Figur 7 zeigt die in Figur 6 angedeutete Detailansicht des vorderen Teils des Haltebügels 8, der mit dem Wischerblatt 3 in Eingriff gelangt, als Schnittansicht. Bevorzugt weist der Haltebügel 8 in dem Bereich, in welchem er bei seiner maximalen Auslenkung - bei αmax mit dem Wischerblatt 3 oder der Querlippe 31 des Wischerblattes 3 in Eingriff steht, einen Aufnahmebereich 86 auf. Der Aufnahmebereich 86 dient insbesondere der Aufnahme des Wischerblattes 3, bzw. der Querlippe 31, und ist zu diesem Zweck bevorzugt als Rücksprung ausgebildet, in welchen das Wischerblatt 3, bzw. die Querlippe 31, eingreifen kann. Besonders bevorzugt ist dabei ein Querschnitt, der zumindest bereichsweise mit dem Wischerblatt 3 oder der Querlippe 31 kongruiert, wie beispielsweise der gezeigte V-förmige Querschnitt. Der Aufnahmebereich 86 verhindert insbesondere, dass bei starker Anpressung des Handreinigers gegen die glatte Fläche 1 das distale Ende des Wischerblattes 3, bzw. die Querlippe 31, entlang des Haltebügels 8 verrutscht und nicht weiter an der glatten Fläche 1 anliegt. FIG. 7 shows the in FIG. 6 indicated detail view of the front part of the retaining clip 8, which engages with the wiper blade 3, as a sectional view. Preferably, the retaining bracket 8 in the region in which it at its maximum deflection - at α max with the wiper blade 3 or the transverse lip 31 of the wiper blade 3 is engaged, a receiving area 86. The receiving area 86 is used in particular for receiving the wiper blade 3, or the transverse lip 31, and is preferably designed as a recess for this purpose, in which the wiper blade 3, or the transverse lip 31, can engage. In this case, a cross-section that at least partially congruents with the wiper blade 3 or the transverse lip 31, such as, for example, the V-shaped cross section shown, is particularly preferred. In particular, the receiving region 86 prevents the distal end from being pressed against the smooth surface 1 when the hand cleaner is pressed heavily against it of the wiper blade 3, or the transverse lip 31, slips along the retaining clip 8 and does not rest on the smooth surface 1.

Figur 8 zeigt eine Draufsicht der in Fig. 6 gezeigten Ausführung. Erkennbar ist zunächst, dass die Schwenkbolzen 82 bevorzugt einstückig mit dem Haltebügel 8 ausgeführt sind und in Aussparungen am Handreiniger eingreifen. Die Spalte zwischen den Schwenkbolzen 82 und den Aussparungen sind vorzugsweise abgedichtet, um ungewolltes Entweichen von Flüssigkeit zu verhindern. FIG. 8 shows a plan view of in Fig. 6 shown execution. It can be seen, first, that the pivot pins 82 are preferably designed in one piece with the retaining bracket 8 and engage in recesses on the hand cleaner. The gaps between the pivot pins 82 and the recesses are preferably sealed to prevent unwanted escape of liquid.
