Description

Die Erfindung betrifft, flexiblen Reinigungskörper in Gestalt eines Quaders, der im Bereich seiner Unterseite durch eine Scheuerfläche begrenzt ist.The invention relates to flexible cleaning body in shape of a cuboid, in the area of its bottom by a Abrasion area is limited.

Ein solcher Reinigungskörper ist beispielsweise aus der EP-A-600829 bekannt.Such a cleaning body is, for example known from EP-A-600829.

Stand der TechnikState of the art

Reinigungskörper der vorgenannten Art gelangen im Haushalt zur Anwendung. Sie sind von im wesentlichen ziegelsteinförmiger Gestalt, aus Schaumstoff erzeugt und so dimensioniert, daß ein Festhalten während der Durchführung von Reinigungsvorgängen mit einer Hand möglich ist. Der Reinigungskörper wird dabei üblicherweise im Bereich der beiden Seitenflächen mit einer Hand umgriffen und im Bereich von einer Stirnfläche mit dem Zeigefinger berührt. Im Bereich der Längsflächen vorgesehene Griffrillen, die sich parallel zur Längsrichtung erstrecken, sollen dabei sicherstellen, daß der aus flexiblem Material bestehende Reinigungskörper während der Durchführung von Reinigungsvorgängen der aufnehmenden Hand nicht unbeabsichtigt entgleitet. Bedingt durch das große Volumen des in der Handfläche befindlichen Teils des flexiblen Reinigungskörpers gelingt das nur sehr unbefriedigend, weil eine starke Zusammenpressung des Reinigungskörpers zugleich eine Beeinträchtigung der Form der Scheuerfläche bedingt sowie eine Verminderung der verbleibenden Saugfähigkeit. Die Reinigung schwer zugänglicher Ecken und Hohlkehlen ist mit dem bekannten Reinigungskörper schwierig.Cleaning bodies of the type mentioned arrive in the household to use. They are essentially brick-shaped Shape, made of foam and dimensioned so that holding on while performing cleaning operations is possible with one hand. The cleaning body is usually in the area of the two side surfaces gripped with one hand and in the area of an end face touched with the index finger. Provided in the area of the longitudinal surfaces Grip grooves that extend parallel to the longitudinal direction should ensure that the flexible Material existing cleaning body during the implementation not inadvertently from cleaning processes of the receiving hand slips away. Due to the large volume of the part of the flexible cleaning body located in the palm of the hand it only works very unsatisfactorily because it is strong Compression of the cleaning body is also an impairment the shape of the abrasive surface and a Reduction of the remaining absorbency. The cleaning difficult to access corners and fillets is with the known Cleaning body difficult.

Der Erfindung liegt die Aufgabe zugrunde, einen solchen Reinigungskörper derart weiterzuentwickeln, daß schwer zugängliche Hohlkehlen und Ecken besser zu reinigen sind und daß sich unter Vermeidung einer verkrampften Handhaltung eine bessere Festlegung des Reinigungskörpers in der aufnehmenden Hand ergibt.The invention has for its object such a cleaning body to develop in such a way that difficult to access Fillets and corners are easier to clean and that a better one while avoiding a cramped hand position Fixing the cleaning body in the receiving hand results.

Darstellung der ErfindungPresentation of the invention

Erfindungsgemäß sind zur Lösung dieser Aufgabe bei einem Reinigungskörper der eingangs genannten Art die kennzeichnenden Merkmale von Anspruch 1 vorgesehen. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.According to the invention to solve this problem with a cleaning body of the type mentioned at the outset Features of claim 1 provided. On advantageous configurations refer to the subclaims.

Bei dem erfindungsgemäßen Reinigungskörper ist es vorgesehen, daß zumindest die den Quader am hinteren Ende begrenzende Stirnfläche einerseits durch eine scharfe Kante und andererseits durch eine Schrägfläche begrenzt ist, die zwischen der Stirnfläche und den angrenzenden Seitenflächen angeordnet sind. Unter dem hinteren Ende ist in diesem Zusammenhang das von dem Benutzer während einer Benutzung des Reinigungskörpers wegzeigende Ende zu verstehen.In the cleaning body according to the invention, it is provided that that at least the boundary of the cuboid at the rear end Front face on the one hand by a sharp edge and on the other hand is delimited by an inclined surface between the End face and the adjacent side surfaces arranged are. In this context, this is under the rear end by the user during use of the cleaning body understanding the end pointing away.

Die Form des Reinigungskörpers ist verhältnismäßig einfach erzeugbar. Sie bedingt dennoch eine Annäherung an die sich bei einer Greifbewegung ergebende, anatomische Form der menschlichen Hand. Die den Reinigungskörper während der bestimmungsgemäßen Verwendung festlegenden Berührungszonen erfahren dadurch eine deutliche Vergrößerung, was die Festlegungssicherheit verbessert und vermeidet, daß sich eine verkrampfte Handhaltung ergibt. Außerdem besteht die Möglichkeit, die sich beiderseits an die scharfe Kante anschließenden Begrenzungszonen der Seiten- und Stirnfläche des Reinigungskörpers zwischen Daumen und Zeigefinger zu verpressen bis zur Porenfreiheit und den Reinigungskörper auf diese Weise nochmals besser festzulegen, ohne daß sich eine nennenswerte Verformung der Scheuerfläche ergibt. Unter Vermeidung von punktuellen Überbelastungen des aus flexiblem Material bestehenden Reinigungskörpers bzw. der menschlichen Hand wird dadurch eine besonders gute Festlegung auf bequeme Weise erreicht. Für eine unverkrampfte Benutzung des Reinigungskörpers während einer länger anhaltenden Benutzungsdauer ist das von großem Vorteil. Auch ist es nicht erforderlich, den Reinigungskörper unter Beeinträchtigung seiner Saugfähigkeit stärker zu verformen, um einen festen Sitz zu gewährleisten. Hinsichtlich der schnellen Aufnahme von gelöstem Schmutz ist das von großem Vorteil.The shape of the cleaning body is relatively simple can be generated. It nevertheless requires an approximation to itself anatomical form of the gripping movement human hand. The cleaning body during the intended Experience the use of defined contact zones thereby a significant enlargement, which is certainty improves and avoids that a cramped Hand position results. There is also the possibility which adjoin the sharp edge on both sides Boundary zones of the side and face of the cleaning body between your thumb and forefinger up to the absence of pores and the cleaning body in this way to be determined even better, without being worth mentioning Deformation of the abrasion surface results. Avoiding from selective overloading of the flexible material existing cleaning body or the human hand thereby achieving a particularly good definition in a convenient manner. For a relaxed use of the cleaning body during a long period of use it is of great advantage. Nor is it necessary to use the cleaning body impairing its absorbency deform more to ensure a tight fit. Regarding the quick absorption of loosened dirt this is a great advantage.

Ein weiterer Vorteil resultiert daraus, daß der Reinigungskörper neben der Scheuerfläche und der scharfen Kante eine Schrägfläche aufweist, die es in Verbindung mit den angrenzenden Teilen der Stirn- und Seitenfläche gestattet, Schmutz aus Hohlkehlen und schwer zugänglichen Ecken zu entfernen.Another advantage results from the fact that the cleaning body next to the scouring surface and the sharp edge Inclined surface that it in connection with the adjacent Part of the face and side surface allowed dirt to be removed from fillets and hard-to-reach corners.

Der Reinigungskörper kann aus irgendeinem oder mehreren der einschlägig verwendeten Werkstoffe erzeugt sein, beispielsweise aus einem flexiblen Textil- und/oder Schaumstoffblock. Gelangen mehrere Werkstoffe in Kombination miteinander zur Anwendung, beispielsweise eine Schicht aus Polyurethanschaum und eine Schicht aus einem Textilmaterial, dann können die einzelnen Schichten unlösbar oder lösbar aneinander festgelegt sein. Im letztgenannten Falle ist es beispielsweise möglich, diesbezüglich Klettverschlußelemente zu verwenden.The cleaning body can be made from any one or more of the relevant materials used to be generated, for example from a flexible block of textile and / or foam. If several materials come together in combination Application, for example a layer of polyurethane foam and a layer of a textile material, then the individual layers non-detachably or releasably attached to each other his. In the latter case it is possible, for example, to use Velcro in this regard.

Als vorteilhaft hat es sich bewährt, wenn die scharfe Kante am linken und die Schrägfläche am rechten Ende der hinteren Stirnfläche angeordnet ist. Bei einer Verwendung in der rechten Hand, die meisten Anwender sind Rechtshänder, gelangt die scharfe Kante bei einer solchen Ausbildung automatisch in den Bereich zwischen Daumen und Zeigefinger, wo sie sicher umgriffen werden kann. It has proven to be advantageous if the sharp edge on the left and the sloping surface on the right end of the rear End face is arranged. When used in the right Hand, most users are right-handed, the reaches sharp edge in such training automatically in the The area between the thumb and forefinger where they are securely gripped can be.

Nach einer anderen Ausgestaltung ist es vorgesehen, daß die den Quader begrenzenden Seiten- und Stirnflächen an zwei einander diagonal gegenüberliegenden Enden durch die Schrägfläche verbunden sind und einander an den übrigen Enden in der scharfen Kante begrenzen. Beim Aufnehmen eines solchen Reinigungskörpers ist es nicht mehr erforderlich auf die jeweiligen Lage zu achten. Unabhängig hiervon gelangt stets eine scharfe Kante und eine Schrägfläche in den Bereich des hinteren Endes, wo die Kante leicht ergriffen werden kann. Für die praktische Verwendung ist das von großem Vorteil.According to another embodiment, it is provided that the the side and end faces delimiting the cuboid on two each other diagonally opposite ends through the inclined surface are connected and mutually at the other ends in the limit sharp edge. When taking up such a cleaning body it is no longer necessary on the particular Able to pay attention. Regardless of this, one always arrives sharp edge and an inclined surface in the area of the rear End where the edge can be easily gripped. For the practical use is a great advantage.

Die Seitenflächen können in an sich bekannter Weise mit sich parallel zur Längsrichtung erstreckenden Griffrillen versehen sein, beispielsweise mit einer Griffrille, die von sinusförmigem Profil ist und abgerundet in die Oberseite des Reinigungskörpers übergeht.The side surfaces can be in a manner known per se Grip grooves extending parallel to the longitudinal direction be, for example with a grip groove that is sinusoidal Profile is rounded and in the top of the cleaning body transforms.

Um die Tragfähigkeit des flexiblen Reinigungskörpers im Bereich der Stirnfläche nicht unnötig zu schwächen hat es sich als vorteilhaft bewährt, wenn die Griffrillen und die Schrägfläche einander in einer zweiten Kante dergestalt durchschneiden, daß im Bereich der eigentlichen Stirnflächen keine Griffrille vorhanden ist. Da ein Festhalten des Reinigungskörpers in diesem Bereich ohnehin nur parallel zur Scheuerfläche möglich ist entsteht dadurch kein Nachteil. Es ergibt sich jedoch der Vorteil, daß die Übertragung hoher Anpreßkräfte an die zu reinigende Fläche auch im Bereich der Stirnfläche möglich ist, was die Durchführung von Scheuerprozessen begünstigt.To the load capacity of the flexible cleaning body in the area the face has not weakened unnecessarily proven to be advantageous when the grip grooves and the inclined surface intersect each other in a second edge so that in the area of the actual end faces none Grip groove is present. Since holding the cleaning body in this area anyway only parallel to the scouring surface there is no disadvantage. It results However, there is the advantage that the transfer of high contact forces to the surface to be cleaned, also in the area of the end face what is possible is the implementation of scrubbing processes favored.

Nach einer anderen Ausgestaltung ist es vorgesehen, daß die Schrägfläche einen Bestandteil einer Abrundung bildet. Diese kann gleichmäßig in die jeweilige Stirn- und Seitenfläche auslaufen, was die Verwendbarkeit beim Auswischen von Hohlkehlen weiter verbessert und das Reinigen von Töpfen und Küchengeschirr vereinfacht.According to another embodiment, it is provided that the Inclined surface forms part of a rounding. This can evenly in the respective front and side surface leak, which is the usability when wiping fillets further improved and cleaning pots and kitchen ware simplified.

Als vorteilhaft hat es sich bewährt, wenn die Abrundung einen Radius aufweist, der 0,2 bis 0,5 mal so groß ist wie die Breite des Quaders, vorzugsweise 0,3 bis 0,4 mal so groß. Bei einer üblichen Breite von 60 bis 80 mm vermag sich der Gelenkbogen des Daumens bei einer solchen Ausbildung besonders harmonisch im Bereich der Abrundung an den Reinigungskörper anzulegen, was diesem einen festen Halt verleiht.It has proven to be advantageous if the rounding off is one Radius that is 0.2 to 0.5 times as large as that Width of the cuboid, preferably 0.3 to 0.4 times as large. At the articulated bow is capable of a usual width of 60 to 80 mm the thumb especially with such training harmonious in the area of rounding off the cleaning body put on what gives it a firm hold.

Die Unterseite gelangt in vielen Fällen zur Anwendung, um festhaftende Schmutzbestandteile mechanisch zu lösen. Um bei einem solchen Arbeitsvorgang eine direkt angrenzende Seitenfläche gleich mit reinigen zu können, beipielsweise die Seitenwand eines Topfes im Bereich des Bodens, hat es sich als vorteilhaft bewährt, wenn das Profil des Reinigungskörpers in diesem Bereich scharfkantig begrenzt ist.The bottom is used in many cases to to loosen adherent dirt components mechanically. To at such an operation, a directly adjacent side surface to be able to clean at the same time, for example the side wall a pot in the area of the bottom, it has proven to be proven advantageous if the profile of the cleaning body in this area is sharply delimited.

Es ist nicht unbedingt erforderlich, daß die Seiten- und Stirnflächen miteinander einen Winkel einschließen, der exakt 90° beträgt. Im Hinblick auf die ergonomischen Gegebenheiten der menschlichen Hand hat es sich vielmehr als vorteilhaft bewährt, wenn die beiden Flächen an der Stelle, an der sich einander scharfkantig abgrenzen, einen Winkel von weniger als 90° miteinander einschließen, beispielsweise einen Winkel von 60 bis 85°. Die porenfreie Zusammenpressung des den Reinigungskörper bildenden Werkstoffblocks zum sicheren Festhalten wird dadurch wesentlich erleichtert.It is not absolutely necessary that the side and End faces form an angle with each other that is exact Is 90 °. With regard to the ergonomic conditions Rather, it has proven beneficial to the human hand proven if the two surfaces at the point where demarcate each other with sharp edges, an angle of less than Include 90 ° with each other, for example an angle of 60 to 85 °. The non-porous compression of the cleaning body forming material blocks for secure holding it will be much easier.

Bei dem gezeigten Ausführungsbeispiel ist es vorgesehen, daß die den Quader begrenzenden Seitenflächen 2, 3 und die Stirnflächen 4, 5 an zwei aneinander diagonal gegenüberliegenden Enden durch eine Abrundung 11.1 verbunden sind und einander an den übrigen Enden in einer scharfen Kante 9 durchschneiden. Die eine der scharfen Kanten begrenzt die hintere Stirnfläche am linken Ende. Die Seitenflächen 2,3 und die Stirnflächen 4,5 schließen miteinander einen Winkel von 75° ein. Der Reinigungskörper läßt sich dadurch im Bereich der Kanten 9 besonders fest ergreifen, ohne daß es zu örtlichen Überbeanspruchungen des ihn bildenden, flexiblen Werkstoffes kommt bzw. zu starken Dimensionsveränderungen oder Verformungen der Scheuerfläche. Eine Beeinträchtigung der Verwendbarkeit oder ein unbeabsichtigtes Entgleiten ist dadurch nicht ohne weiteres zu befürchten. Auch im Hinblick auf die Vermeidung von Ermüdungserscheinungen der den Reinigungskörper führenden, menschlichen Hand ist das von großem Vorteil. Die Scheuerfläche 1 ist mit einer scheueraktiven, flüssigkeitsdurchlässigen Beschichtung aus einem elastomeren Polyurethan versehen.In the embodiment shown, it is provided that the side faces 2, 3 delimiting the cuboid and the end faces 4, 5 on two diagonally opposite one another Ends are connected by a rounding 11.1 and each other Cut through the other ends in a sharp edge 9. One of the sharp edges delimits the rear face at the left end. The side faces 2, 3 and the end faces 4,5 form an angle of 75 ° with each other. The cleaning body can be in the area of the edges 9 hold particularly tightly without causing local overuse of the flexible material that forms it or excessive dimensional changes or deformation of the Abrasion surface. An impairment of usability or unintended slipping is not easy to fear. Also with a view to avoiding Fatigue of the cleaning body, this is of great advantage to human hands.

Bei der in Fig. 5 gezeigten Ausführung ist die den Quader am hinteren Ende begrenzende Stirnfläche 5 einerseits durch eine Schrägfläche 11 und andererseits durch eine scharfe Kante 9 begrenzt, wobei die Stirnfläche mit der Längsrichtung der Seitenflächen 2, 3 einen Winkel A von etwa 70° anschließt und die Schrägfläche einen stumpfen Winkel B von 150°. Die vordere Stirnfläche 4 schließt mit der Längsrichtung der Seitenflächen 2, 3 einen rechten Winkel ein.In the embodiment shown in FIG. 5, the cuboid is on rear end delimiting end face 5 on the one hand by a Inclined surface 11 and on the other hand by a sharp edge 9 limited, the end face with the longitudinal direction of the Side surfaces 2, 3 connects an angle A of about 70 ° and the inclined surface has an obtuse angle B of 150 °. The front one End face 4 closes with the longitudinal direction of the side faces 2, 3 a right angle.

Die Schrägflächen 11 lassen sich bei den Ausführungen nach den Fig. 4 und 5 besonders einfach durch einen geraden Schnitt und abfallfrei erzeugen. Dennoch gelingt es auch in diesem Falle aufgrund der elastischen Verformbarkeit des den Reinigungskörper bildenden Werkstoffblocks Hohlkehlen und Abrundungen beispielsweise von Haushaltsgeschirr besonders einfach auszuwischen.The inclined surfaces 11 can be in the versions 4 and 5 particularly simply by a straight Cut and create waste-free. Nevertheless, it also succeeds in this case due to the elastic deformability of the Blocks of fillets forming fillets and fillets of household dishes, for example, is particularly simple to wipe.
