Description

Die vorliegende Erfindung betrifft einen Gerätekopf für ein handbedientes Saugreinigungsgerät zum Reinigen von Böden und Wänden von Schwimmbecken oder Schwimmteichen mit einer wasserdichten Folienverkleidung.The present invention relates to a device head for a hand-operated Saugreinigungsgerät for cleaning floors and walls of swimming pools or swimming ponds with a waterproof film cladding.

Derartige Schwimmbecken oder Schwimmteiche sind typischerweise aus Kunststoff, aus Metall, insbesondere aus Edelstahl, oder aus sonstigem Material hergestellt.Such swimming pools or swimming ponds are typically made of plastic, metal, especially stainless steel, or other material.

Stand der TechnikState of the art

Solche Geräteköpfe sind unter den Handelsbezeichnungen "Bürsten für Bodensauger", "Schwimmbadbodensauger" oder "Pool-Bodensaugerbürsten" seit langem bekannt und auch Gegenstand zahlreicher Schutzrechte. Sie dienen der rein mechanischen Reinigung der Beckenoberfläche von anhaftendem Schmutz, eingeschlepptem Sand und insbesondere von anhaftendem biologischem Belag, wie beispielsweise Algenbewuchs.Such device heads have long been known under the trade names "brushes for floor vacuum cleaner", "pool floor vacuum cleaner" or "pool floor brushes" and also the subject of numerous industrial property rights. They are used for the purely mechanical cleaning of the pelvic surface of adhering dirt, introduced sand and in particular of adhering biological coating, such as algae growth.

Gattungsgemäße Geräteköpfe sind beispielsweise aus US2004/0158943 , EP1234932 , DE9404748 U und US3707737 bekannt.Generic device heads are for example off US2004 / 0158943 . EP1234932 . DE9404748 U and US3707737 known.

Die Bodensaugerbürste arbeitet dabei mit einer externen oder internen Pumpe zusammen, welche das Beckenwasser durch die Borsten der Bürste hindurch ansaugt und dabei die Verunreinigungen mitsaugt. Die Bodensaugerbürste besteht aus einem unten offenen Saugkasten, einem Wasserdurchtrittsloch, das in einem Anschlussstutzen für einen Saugschlauch mündet und einem Teil zur Befestigung einer Teleskopstange, mittels welcher die Bodensaugerbürste von Hand über die Beckenoberfläche geführt wird.The bottom suction brush works together with an external or internal pump, which sucks the pool water through the bristles of the brush and thereby sucks the impurities. The bottom suction brush consists of a bottom open suction box, a water passage hole, which opens into a connection piece for a suction hose and a part for fixing a telescopic rod, by means of which the bottom suction brush is guided by hand over the pool surface.

Der Saugkasten weist bei zahlreichen dieser Bodensaugerbürsten Strömungsstege auf, die zum Wasserdurchtrittsloch hin ausgerichtet sind. Die nach unten gerichteten, vorstehenden Ränder des Saugkastens und die Strömungsstege sind üblicherweise mit etwa 10 bis 14 Millimeter langen Kunststoffborsten bestückt, welche den an der Beckenoberfläche anhaftenden biologischen Belag von der Beckenoberfläche ablösen sollen. Die abgelösten Verunreinigungen werden dann mit dem durch die Borsten angesaugten Beckenwasser über den Saugschlauch zu einer Filteranlage befördert, wo sie durch das Filtermaterial vom Beckenwasser getrennt werden.In many of these bottom suction brushes, the suction box has flow webs which are aligned with the water passage hole. The downwardly projecting edges of the suction box and the flow webs are usually equipped with about 10 to 14 millimeters long plastic bristles, which should replace the adhering to the pool surface biological coating from the pool surface. The detached impurities are then transported with the sucked by the bristles pool water via the suction hose to a filter system, where they are separated by the filter material from the pool water.

Alle diese bekanten Vorrichtungen weisen jedoch den Nachteil auf, dass sie den auf der Beckenoberfläche anhaftenden biologischen Belag nur unzureichend ablösen, weshalb eine häufige Reinigung der Beckenoberfläche unabdingbar ist, um das optisch saubere Erscheinungsbild des Beckens zu erhalten. Dies wird insbesondere bei steigenden Wassertemperaturen, vermehrter Sonneneinstrahlung und ganz besonders bei einer länger dauernden Reinigungsunterbrechung, beispielsweise durch urlaubsbedingte Abwesenheit des Besitzers zum Problem. Der einmal an der Beckenoberfläche festgesetzte biologische Belag vermehrt sich dort rasant und führt innerhalb kurzer Zeit zu einem schmutzigen Erscheinungsbild.However, all these known devices have the disadvantage that they dissolve the adhering to the surface of the pool surface only insufficient, so frequent cleaning of the pelvic surface is essential to maintain the optically clean appearance of the pelvis. This becomes a problem especially with increasing water temperatures, increased solar radiation and especially with a longer-lasting cleaning interruption, for example due to vacation-related absence of the owner. The once fixed on the pelvic surface biological plaque multiplies rapidly there and leads within a short time to a dirty appearance.

Dabei ist die Vermehrungsrate des biologischen Belags abhängig vom vorhandenen Befall. Je gründlicher der Belag bei der Reinigung der Beckenoberfläche abgelöst werden kann, desto länger dauert es, bis eine Neuverschmutzung sichtbar wird. Herkömmliche Beckenreinigungsbürsten lösen jedoch nur die groben Anteile ab, die feinen Belagsanteile bleiben aber an der Beckenoberfläche haften und werden dort nur in der jeweiligen Bürstrichtung ausgerichtet. Um eine effiziente, also porentiefe Reinigung zu erzielen, ist es bisher erforderlich eine Nachreinigung von Hand mit Scheuervliesen durchzuführen. Solche Scheuervliese sind beispielsweise von der Fa. Scotch im Handel. Diese Scheuervliese greifen jedoch die Oberfläche des Beckens, insbesondere bei einer Folienauskleidung, mehr oder weniger stark an und führen zu einem Abrieb, wodurch die Oberfläche ihre ursprünglich glatte Struktur verliert und rau wird. An einer rauen Oberfläche haften die biologischen Beläge jedoch noch besser an und sind noch schwerer ablösbar.The multiplication rate of the biological deposit is dependent on the existing infestation. The more thoroughly the pad can be removed when cleaning the pelvic surface, the longer it takes for new contamination to become visible. However, conventional pool cleaning brushes only remove the coarse fractions, but the fine coating components remain adhered to the pool surface and are aligned there only in the respective brushing direction. In order to achieve an efficient, that is to say pore-deep cleaning, it has hitherto been necessary to carry out a subsequent cleaning by hand with scouring fleeces. Such scouring fleeces are commercially available, for example, from the company Scotch. However, these scrubbers more or less strongly attack the surface of the pelvis, particularly in the case of a film lining, and lead to abrasion, whereby the surface loses its originally smooth structure and becomes rough. On a rough surface, however, the biological deposits adhere even better and are even harder to remove.

Zur schonenden Reinigung von empfindlichen Oberflächen unter Vermeidung des Einsatzes aggressiver Chemikalien haben sich im Haushaltsbereich in den letzten Jahren vermehrt so genannte Mikrofasertücher durchgesetzt. Diese Mikrofasertücher ermöglichen eine porentiefere Reinigung als übliche Scheuerschwämme oder Scheuervliese, ohne die oftmals hochglanzlackierten Möbeloberflächen zu zerkratzen.For the gentle cleaning of sensitive surfaces while avoiding the use of aggressive chemicals, so-called microfibre cloths have increasingly prevailed in the household sector in recent years. These microfibre cloths allow for cleaner cleaning than conventional scouring pads or scouring cloths, without scratching the often glossy furniture surfaces.

Technische AufgabenstellungTechnical task

Die vorliegende Erfindung hat sich die Aufgabe gestellt, einen Gerätekopf für die Reinigung von Beckenoberflächen zu schaffen, der die porentiefe Entfernung des biologischen Belages bei gleichzeitig schonender Oberflächenbehandlung, insbesondere unter Einbeziehung der Materialeigenschaften von Mikrofasertüchern ermöglicht. Mit diesem Gerätekopf soll es ermöglicht werden, ohne zusätzlichem Arbeitsschritt und gleichzeitig mit geringerer körperlicher Anstrengung eine porentiefere Reinigung der Beckenoberfläche zu erzielen als dies mit den bekannten Vorrichtungen derzeit möglich ist. Dafür soll der erfindungsgemäße Gerätekopf mit einer handelsüblichen Teleskopstange bedienbar sein.The object of the present invention has been made to provide a device head for the cleaning of pool surfaces, which allows the pore-depth removal of the biological coating at the same time gentle surface treatment, especially taking into account the material properties of microfiber cloths. With this device head, it should be possible, without additional work and at the same time with less physical effort to achieve a pore-deep cleaning of the pelvic surface than is currently possible with the known devices. For this purpose, the device head according to the invention should be operable with a commercially available telescopic rod.

Allgemeine Beschreibung der ErfindungGeneral description of the invention

Diese Aufgabe wird dadurch gelöst, dass der Gerätekopf gemäß den Merkmalen des Anspruchs 1 ausgebildet ist.This object is achieved in that the device head is formed according to the features of claim 1.

Derzeit muss bei der Führung der Teleskopstange deren Gewicht und das Gewicht der Reinigungsbürste oftmals gegen den Strömungswiderstand und gegen den Biegewiderstand des Saugschlauchs bewegt werden. Insbesondere beim Reinigen der Seitenwände kommt erschwerend noch dazu, dass der Bürstenkopf auch mit einem gewissen Anpressdruck gegen die Seitenwand gedrückt werden muss. Die dabei aufzubringenden Kräfte führen häufig zu Rückenschmerzen.Currently, in the leadership of the telescopic pole whose weight and the weight of the cleaning brush must often be moved against the flow resistance and against the bending resistance of the suction hose. In particular, when cleaning the side walls aggravating even more that the brush head must be pressed against the side wall with a certain contact pressure. The applied forces often lead to back pain.

Als weitere Aufgabe hat sich die Erfindung daher das Ziel gesetzt, in einer besonders bevorzugten Ausführung der Erfindung den Gerätekopf so auszugestalten, dass seine Handhabung über die Teleskopstange weniger Kraftaufwand erfordert als dies bei den bisherigen Vorrichtungen erforderlich ist.Another object of the invention is therefore to set the device head in a particularly preferred embodiment of the invention so that its handling via the telescopic rod requires less effort than is required in the previous devices.

Diese Aufgabe wird gelöst, indem der Textilteil Durchbrüche aufweist, deren Geometrie, Größe und Positionierung so auf den Saugkasten abgestimmt sind, dass der Gerätekopf beim Anlegen an die Beckenseitenwand aufgrund der Saugkraft des durch den Gerätekopf angesaugten Beckenwassers selbsttätig anhaftet, aber leicht verschiebbar bleibt.This object is achieved by the textile part has openings whose geometry, size and positioning are matched to the suction box, that the device head when applying to the basin side wall due to the suction of the suctioned by the device head pool water automatically adheres, but remains easily displaced.

  • Figur 2 den Textilteil in Aufsicht mit der reinigenden Oberflächenseite, abgelöst vom Gerätekopf;
  • Figur 3 den Saugkasten mit abgelöstem Textilteil in Schrägansicht von oben;

In the following the invention will be explained in more detail with reference to an embodiment and figures. It shows:
  • FIG. 1 an embodiment of the device head according to the invention in an oblique view;
  • FIG. 2 the textile part in supervision with the cleaning surface side, detached from the device head;
  • FIG. 3 the suction box with detached textile part in an oblique view from above;
  • FIG. 4 the suction box with detached textile part in top view from below.

Die in den Figuren dargestellte Vorrichtung steht exemplarisch für eine Vielzahl von möglichen Varianten und dient nur der Veranschaulichung des Erfindungsgedankens.The device shown in the figures exemplifies a variety of possible variants and serves only to illustrate the inventive concept.

Der Gerätekopf 1 in Figur 1 besteht aus zwei voneinander lösbaren Bauteilen, nämlich dem Saugkasten 2 und dem Textilteil 3. Der Saugkasten 2 besteht üblicherweise aus einem Kunststoffteil, ist jedoch nicht auf Kunststoff als alleiniges Herstellungsmaterial beschränkt, und ist - wie aus den Figuren 3 und 4 ersichtlich - nach unten bevorzugt vollständig offen. Alternativ kann der Saugkasten aber auch als im Wesentlichen geschlossener Bauteil mit Durchbrüchen an seiner Unterseite ausgebildet sein. Er besitzt in einer bevorzugten Ausführung Einrichtungen 4, beispielsweise Bügel aus nicht rostendem Material auf seiner Oberseite oder an den Seitenrändern, an denen der Textilteil 3 unverrückbar aber lösbar befestigt ist. Alternativ kann der Textilteil 3 so ausgebildet sein, dass seine Befestigung am Saugkasten 2 ohne Einrichtungen 4 erfolgen kann.The device head 1 in FIG. 1 consists of two detachable components, namely the suction box 2 and the textile part 3. The suction box 2 is usually made of a plastic part, but is not limited to plastic as a sole manufacturing material, and is - as from the FIGS. 3 and 4 apparent - down preferably fully open. Alternatively, the suction box can also be designed as a substantially closed component with openings on its underside. He has in a preferred embodiment of facilities 4, for example, bracket made of stainless material on its upper side or on the side edges to which the textile part 3 is immovably but releasably attached. Alternatively, the textile part 3 may be designed so that its attachment to the suction box 2 can take place without means 4.

An der Unterseite weist der Saugkasten 2 in einer bevorzugten Variante erhabene Ränder 7 und strömungsoptimierende Stege 8 auf, welche im Wesentlichen gleiche Höhe besitzen und bevorzugt mit nach unten ragenden Borsten 6 bestückt sind. Bei dieser Variante der Erfindung ist die Unterseite des Textilteils 3 bevorzugt aus Mikrofasern ausgebildet und dient als Haftungsvlies, welches durch die Borsten 6 unverrückbar gehalten wird.On the underside, the suction box 2 in a preferred variant of raised edges 7 and flow-optimizing webs 8, which have substantially the same height and are preferably equipped with downwardly projecting bristles 6. In this variant of the invention, the underside of the textile part 3 is preferably formed of microfibers and serves as a bonding fleece, which is held immovably by the bristles 6.

Auf der Oberseite des Saugkastens 2 befinden sich ein an sich bekanntes Ansatzrohrstück 12 zum Anschluss eines Saugschlauches und ein Stutzen 13 zum Befestigen einer Teleskopstange.On the top of the suction box 2 are a known neck tube piece 12 for connecting a suction hose and a nozzle 13 for attaching a telescopic rod.

Der Textilteil 3 liegt mit seiner Unterseite 5, die in der bevorzugten Ausführung der Erfindung aus Mikrofaser besteht und als Haftvlies ausgebildet ist, an diesen Borsten 6 an, wodurch die Borsten 6 den Textilteil 3 in seiner Lage fixieren. Die Randbereiche 9 und 10 des Textilteils 3 sind in einer Variante der Erfindung über die Schmalseiten des Saugkastens 2 hochgeklappt und verfügen über Mittel 11 mit denen diese Randbereiche zusätzlich an den Einrichtungen 4 des Saugkastens 2 befestigt sind. Bei der lösbaren Verbindung zwischen Saugkasten 2 und Textilteil 3 ist es von Vorteil, wenn die Verbindung ein Nachspannen des Textilteils 3 in einfacher Weise ermöglicht, da sich der Textilteil 3 im durchnässten Zustand bis zu einem gewissen Grad ausdehnt.The textile part 3 lies with its underside 5, which consists in the preferred embodiment of the invention of microfiber and is designed as a non-woven, to these bristles 6, whereby the bristles 6 fix the textile part 3 in its position. The edge regions 9 and 10 of the textile part 3 are folded up in a variant of the invention over the narrow sides of the suction box 2 and have means 11 with which these edge regions are additionally attached to the devices 4 of the suction box 2. In the detachable connection between the suction box 2 and the textile part 3, it is advantageous if the connection allows a re-tensioning of the textile part 3 in a simple manner, since the textile part 3 expands to a certain extent in the wet state.

Alternativ kann der Textilteil 3 mit einer Bindeschnur oder einem Gummizug am Saugkasten 2 befestigt sein. In diesem Fall kann auf die Einrichtungen 4 verzichtet werden. Als weitere Alternative können am Saugkasten 2 Einrichtungen 4 zur Befestigung von Druckknöpfen vorgesehen werden, mit welchen der Textilteil 3 am Saugkasten 2 lösbar befestigt ist. Weiters kann der Saugkasten 2 mit seitlich oder nach oben vorstehenden Noppen ausgerüstet sein an denen der Textilteil 3 mittels Gummischnur lösbar befestigt ist oder die Noppen werden durch Ösen im Textilteil gedrückt. Es versteht sich von selbst, dass noch weitere alternative Möglichkeiten zur lösbaren Befestigung des Textilteils 3 am Saugkasten 2 existieren, deren Aufzählung aus Gründen der Effizienz unterbleibt, die jedoch ebenso wie die beschriebenen Varianten unter diese Erfindung fallen.Alternatively, the textile part 3 may be fastened to the suction box 2 with a tying cord or an elastic band. In this case, the facilities 4 can be dispensed with. As a further alternative means 2 can be provided for the attachment of snaps on the suction box 2, with which the textile part 3 is releasably secured to the suction box 2. Furthermore, the suction box 2 may be equipped with laterally or upwardly projecting nubs on which the textile part 3 is releasably secured by means of rubber cord or the knobs are pressed by eyelets in the textile part. It goes without saying that there are other alternative possibilities for releasable attachment of the textile part 3 on the suction box 2, the enumeration of which is omitted for reasons of efficiency, but which, like the variants described, fall under this invention.

In Figur 2 ist der flache Textilteil 3 abgelöst vom Gerätekopf 1 und ausgebreitet dargestellt. Der Textilteil 3 besitzt eine reinigende Oberseite 14, bevorzugt aus Mikrofasern gefertigt, sowie eine Unterseite 5, ebenfalls bevorzugt aus Mikrofasern gefertigt, welche als Haftungsvlies dienen kann, mit der es beispielsweise an den Kunststoffborsten 6 anliegt und von diesen Kunststoffborsten 6 lagefixierend gehalten wird. Zwischen der Oberseite 14 und der Unterseite 5 sind lagefixierende Versteifungsstäbe 15 und 16 oder in den Figuren nicht dargestellte Versteifungsplatten eingelegt, die insbesondere der Abstützung des Textilteiles 3 in die Schiebe- und Zugrichtung dienen und verhindern, dass bei der Reinigungsbewegung der Textilteil 3 in die Bewegungsrichtung verformt wird. Ohne diese Versteifungsstäbe 15 und 16 oder Versteifungsplatten könnte sich, abhängig vom verwendeten Material des Textilteiles 3 dieser bei der Schiebe- und Zugbewegung bis hinter die Seitenränder 7 bzw. die Kunststoffborsten 6 verschieben, wodurch die Funktionalität des Gerätekopfes 1 stark beeinträchtigt wäre.In FIG. 2 is the flat textile part 3 detached from the device head 1 and shown spread. The textile part 3 has a cleaning upper side 14, preferably made of microfibers, and a bottom 5, also preferably made of microfibers, which can serve as Haftungsvlies, with which it rests, for example, on the plastic bristles 6 and is held by these plastic bristles 6 position fixing. Between the top 14 and the bottom 5 are Position fixing stiffening rods 15 and 16 or in the figures, not shown stiffening plates inserted, which serve in particular the support of the textile part 3 in the sliding and pulling direction and prevent that during the cleaning movement of the textile part 3 is deformed in the direction of movement. Without these stiffening rods 15 and 16 or stiffening plates could, depending on the material used of the textile part 3 of these move in the sliding and pulling movement to behind the side edges 7 and the plastic bristles 6, whereby the functionality of the device head 1 would be severely impaired.

Mikrofasern haben sich in Bezug auf die schonende und gleichzeitig porentiefe Reinigung als besonders wirksam herausgestellt. Alternativ kann der Textilteil 3 aber auch aus Naturfasern, beispielsweise aus Baumwolle oder Leinen, aus anderen Kunstfasern, aus Mineralfasern, aus beschichteten oder vergüteten Fasern oder aus einem Mischgewebe aus mehreren dieser Fasern oder aus einer Kombination aus mehreren dieser Fasern bestehen. Alternativ ist auch der Einsatz eines Trägergewebes mit einem darauf aufgebrachten Kunststoffschaum möglich.Microfibers have proven to be particularly effective in terms of gentle and deep pore cleaning. Alternatively, however, the textile part 3 may also consist of natural fibers, for example of cotton or linen, of other synthetic fibers, of mineral fibers, of coated or tempered fibers or of a mixed fabric of several of these fibers or of a combination of several of these fibers. Alternatively, the use of a carrier fabric with a plastic foam applied thereto is also possible.

In einer besonders bevorzugten Ausführung sind in die aus Mikrofasern bestehende Oberseite 14 des Textilteils 3 zusätzliche Fasern eingelagert, die eine gröbere und härtere Materialstruktur besitzen als die Mikrofasern. Diese zusätzlichen Fasern können ebenfalls aus Kunststoff oder aus Naturfasern oder aus jeder anderen, vorstehend aufgezählten Faser bestehen. Mit diesen Fasern werden die groben Anteile des biologischen Belages von der Beckenoberfläche leichter abgelöst, die Mikrofasern bewirken hier bevorzugt die porentiefe Ablösung des biologischen Belages von der Beckenoberfläche.In a particularly preferred embodiment, additional fibers which have a coarser and harder material structure than the microfibers are embedded in the upper side 14 of the textile part 3 consisting of microfibers. These additional fibers may also be made of plastic or natural fibers or any other fiber listed above. With these fibers, the coarse fractions of the biological coating are more easily detached from the pelvic surface, the microfibers here preferably effect the pore-deep detachment of the biological coating from the pelvic surface.

In einer weiteren besonders bevorzugten Ausführung sind die Fasern an der Oberseite 14 des Textilteils 3 streifenförmig zwischen den Streifen aus Mikrofasern eingelegt, und zwar bevorzugt in Querrichtung zur Schiebe- bzw. Zugrichtung des Gerätekopfes 1. Dabei hat es sich als vorteilhaft herausgestellt, wenn die Breite der Streifen aus Mikrofasern erheblich größer ist als die Breite der Faserstreifen aus anderen Fasern. Neben einer streifenförmigen Anordnung sind natürlich auch andere Anordnungen denkbar und von der vorliegenden Erfindung erfasst.In a further particularly preferred embodiment, the fibers are inserted at the top 14 of the textile part 3 in strips between the strips of microfibers, preferably in the transverse direction to the sliding or pulling direction of the device head 1. It has proved to be advantageous if the width the strip of microfibers is considerably larger than the width of the fiber strips from other fibers. In addition to a strip-like arrangement, of course, other arrangements are conceivable and covered by the present invention.

Die Unterseite 5 des Textilteils 3, ebenfalls bevorzugt aus Mikrofasern gefertigt, liegt in einer alternativen Ausführung der Erfindung an den Kunststoffborsten 6 der Ränder 7 und Stege 8 des Saugkastens 2 an und verhindert in Kombination mit den Kunststoffborsten 6 des Saugkastens 2 das Verrutschen des Textilteiles 3. Der Textilteil 3 besitzt zusätzliche Mittel 11 zur Befestigung des Textilteiles 3 am Saugkasten 2, bevorzugt an Einrichtungen 4 auf der Oberseite oder an den Seitenrändern des Saugkastens 2. Dabei können die Einrichtungen 4 beispielsweise starre Bügel aus nicht rostendem Material, und die Mittel 11 zur Befestigung des Textilteiles 3 Klettverschlüsse sein. Wie vorstehend ausgeführt ist aber auch eine Vielzahl von alternativen lösbaren Verbindungen zwischen Textilteil 3 und Saugkasten 2 möglich.The underside 5 of the textile part 3, likewise preferably made of microfibers, abuts the plastic bristles 6 of the edges 7 and webs 8 of the suction box 2 in an alternative embodiment of the invention and prevents the textile part 3 from slipping in combination with the plastic bristles 6 of the suction box 2 The textile part 3 has additional means 11 for attachment of the textile part 3 on the suction box 2, preferably on means 4 on the top or on the side edges of the suction box 2. The devices 4, for example, rigid bracket made of stainless material, and the means 11 for Attaching the textile part 3 Velcro closures be. As stated above, however, a multiplicity of alternative detachable connections between textile part 3 and suction box 2 is also possible.

Das Textilteil 3 dehnt sich beim Eintauchen ins Beckenwasser etwas aus, weshalb es nach der Durchfeuchtung nachgespannt werden sollte. Die Kombination aus Bügeln und Klettverschlüssen hat sich hier als einfache und rasche Methode zur Befestigung und Nachspannung des Textilteils 3 bewährt.The textile part 3 expands when immersed in the pool water something, so it should be re-tensioned after moisture. The combination of hangers and hook-and-loop fasteners has proved to be a simple and quick method for fastening and tensioning the textile part 3 here.

Im Textilteil 3 sind zwischen der Oberseite 14 , welche an die Beckenoberfläche angelegt wird, und der Unterseite 5, welche als Haftungsvlies an den Kunststoffborsten 6 anliegt, mehrere Versteifungsstäbe 15 und 16 eingearbeitet. In einer bevorzugten Ausführung befindet sich je ein Versteifungsstab 15 am Außenrand der Seitenteile 9 und 10 des Textilteiles 3 in unmittelbarer Nachbarschaft zu den Mitteln 11 zur Befestigung des Textilteiles 3. Diese Versteifungsstäbe 15 dienen zur Verzugsreduzierung durch das Befestigen des Textilteils 3 am Saugkasten 2. Die weiteren Versteifungsstäbe 16 sind parallel zu den äußeren Versteifungsstäben 15 über die Fläche des Textilteils verteilt angeordnet. Diese Versteifungsstäbe 16 verhindern, dass bei der Schiebe- und Zugsbewegung des Gerätekopfes 1 der Textilteil 3 hinter die Borsten 6 des Saugkastens 2 verrutscht. Je nach Geometrie des Textilteils können die Versteifungsstäbe 16 aber auch in anderer Anordnung sinnvoll sein.In the textile part 3, a plurality of reinforcing rods 15 and 16 are incorporated between the top 14, which is applied to the pool surface, and the bottom 5, which rests as Haftungsvlies on the plastic bristles 6. In a preferred embodiment, there is a respective stiffening rod 15 at the outer edge of the side parts 9 and 10 of the textile part 3 in the immediate vicinity of the means 11 for fixing the textile part 3. These stiffening rods 15 are used to reduce distortion by attaching the textile part 3 on the suction box 2. Die further stiffening rods 16 are arranged distributed parallel to the outer stiffening rods 15 over the surface of the textile part. These stiffening rods 16 prevent the textile part 3 from slipping behind the bristles 6 of the suction box 2 during the sliding and pulling movement of the device head 1. Depending on the geometry of the textile part, the stiffening rods 16 can also be useful in other arrangements.

In einer bevorzugten Weiterentwicklung der Erfindung weist das Textilteil 3 Durchbrüche 17 auf, die in ihrer Größe, Geometrie und Anordnung auf die Geometrie des Saugkastens 2 so abgestimmt sind, dass der Gerätekopf 1 beim Anlegen an die senkrechte Beckenseitenfläche aufgrund der Saugwirkung durch das angesaugte Beckenwasser selbsttätig in seiner Lage verbleibt und nicht nach unten abrutscht, aber dennoch mit geringem Kraftaufwand hin und her bewegt werden kann. Mit dieser Weiteentwicklung der Erfindung wird es ermöglicht, die Beckenreinigung insgesamt mit geringerem Kraftaufwand durchzuführen als dies bei Beckenreinigungsbürsten nach dem Stand der Technik möglich ist.In a preferred further development of the invention, the textile part 3 has apertures 17 whose size, geometry and arrangement are based on the geometry of the suction box 2 are tuned so that the device head 1 when applying to the vertical side of the basin due to the suction by the sucked pool water automatically remains in position and does not slip down, but still can be moved back and forth with little effort. With this Weiteentwicklung the invention, it is possible to perform the total pool cleaning with less effort than is possible with pool cleaning brushes according to the prior art.

Die Anzahl und Anordnung der Versteifungsstäbe 16 ist hier abhängig von der Anzahl und der Anordnung der Durchbrüche 17 im Textilteil 3.The number and arrangement of the stiffening rods 16 is here dependent on the number and the arrangement of the openings 17 in the textile part. 3

Die Vorteile der Erfindung sind einmal die wesentlich verbesserte Reinigung der Beckenoberfläche von anhaftendem biologischem Belag, insbesondere durch die Reinigungswirkung der Mikrofasern, wodurch das Zeitintervall zwischen zwei Reinigungsvorgängen erheblich vergrößert werden kann und andererseits die schonendere Reinigung der Beckenoberfläche im Gegensatz zu den bisher üblichen groben Borsten oder Scheuervliesen. Die Beckenoberfläche bleibt glatt und bietet damit schlechtere Voraussetzungen für das neuerliche Anhaften von biologischem Belag. Zudem werden die Schweißnähte von Beckenfolien besser geschont, wodurch die Lebensdauer der Beckenfolien erheblich verlängert wird.The advantages of the invention are once the significantly improved cleaning of the pelvic surface of adherent biological coating, in particular by the cleaning effect of the microfibers, whereby the time interval between two cleaning operations can be significantly increased and on the other hand, the gentler cleaning of the pool surface in contrast to the usual coarse bristles or scouring pads. The pelvic surface remains smooth and thus provides worse conditions for the renewed adherence of biological coating. In addition, the weld seams of pelvic films are better protected, whereby the life of the pelvic films is considerably extended.

Beim Einsatz eines Textilteils 3 mit Durchbrüchen 17, ergibt sich zusätzlich der Vorteil, dass die manuelle Reinigung mit erheblich geringerem Kraftaufwand durchgeführt werden kann, wodurch der Ausbildung gesundheitlicher Beschwerden vorgebeugt wird.When using a textile part 3 with openings 17, there is the additional advantage that manual cleaning can be carried out with considerably less effort, whereby the formation of health problems is prevented.
