Description

Die Erfindung betrifft eine Verschlussanordnung zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit, insbesondere zum Abdecken von Schwimmbecken, welche zumindest zwei Basiselemente umfasst, wobei das Basiselement eine Hohlkammer aufweist, wobei wenigstens ein Basiselement mit einer seiner Längsseiten mit einer dieser gegenüberliegenden Längsseite eines benachbarten Basiselements zumindest abschnittsweise beweglich über wenigstens ein Verbindungsmittel verbunden ist und an der, der mit dem Verbindungsmittel verbundenen Längsseite gegenüberliegenden Längsseite wenigstens eine Verbindungseinrichtung aufweist.The invention relates to a closure arrangement for covering open containers with a liquid therein, in particular for covering swimming pools, which comprises at least two base elements, the base element having a hollow chamber, at least one base element having one of its long sides with an opposite long side of an adjacent one Base element is movably connected at least in sections via at least one connecting means and has at least one connecting device on the longitudinal side opposite the longitudinal side connected to the connecting means.

Derartige Verschlussanordnungen zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit sind im Stand der Technik beschrieben.
So beschreibt beispielsweise die DE 196 46 117 C1 einen Solarrollladen für Schwimmbadabdeckungen, bei der jeder Rollladenstab eine Anzahl geschlossener Kammern (Hohlkammern), einen im Querschnitt T-förmigen Kupplungssteg und eine den Kupplungssteg aufnehmende, eine schlitzartige Öffnung aufweisende Aufnahme, besitzt und wobei jeder Rollladenstab auf seiner Oberseite aus transparentem Kunststoff besteht und seine Unterseite mit dunkler Farbe beschichtet oder durchgefärbt ist. Diese Rollladenstäbe sind in ihrer Herstellung insbesondere durch die unterschiedliche Beschichtung bzw. Färbung einzelner Bestandteile kostenaufwendig herzustellen.
Ein weiterer Nachteil dieser Rollladenstäbe und der daraus herzustellenden Schwimmbadabdeckungen besteht darin, dass mindestens die zwei Hohlkammern an den freien Enden eines jeden Rollladenstabes flüssigkeitsdicht zu verschließen sind, sodass die Schwimmbadabdeckung ihre Funktion erst erfüllen kann.
Ein weiterer Nachteil dieser Schwimmbadabdeckung besteht darin, dass bei Einführen des Kupplungssteges in die Aufnahmekammer, welches zur Herstellung einer Schwimmbadabdeckung erforderlich ist, diese Verbindung gegen Längsverschiebungen der einzelnen Rollladenstäbe zusätzlich zu sichern ist.Closure arrangements of this type for covering open containers with a liquid therein are described in the prior art.
For example, the DE 196 46 117 C1 a solar roller shutter for swimming pool covers, in which each roller shutter rod has a number of closed chambers (hollow chambers), a coupling web with a T-shaped cross-section and a slot-like opening that accommodates the coupling web, and each roller shutter rod is made of transparent plastic on its top and its Underside is coated with dark color or colored through. These roller shutter slats are expensive to manufacture, in particular due to the different coating or coloring of individual components.
Another disadvantage of these roller shutter slats and the swimming pool covers to be produced from them is that at least the two hollow chambers at the free ends of each roller shutter slat are to be closed in a liquid-tight manner, so that the swimming pool cover can only fulfill its function.
Another disadvantage of this swimming pool cover is that when the coupling web is inserted into the receiving chamber, which is required to produce a swimming pool cover, this connection must be additionally secured against longitudinal displacements of the individual roller shutter bars.

Eine weitere Verschlussanordnung zum Abdeckung von offenen Behältern mit einer darin befindlichen Flüssigkeit ist beispielsweise in der DE 195 08 953 C1 beschrieben. Dieser Hohlkörper aus Metall oder Kunststoff mit mindestens einer axialen Kammertrennwand und einem wasserdichten Verschluss, der aus einer mit Einfüll- und Entlüftungsöffnungen versehenen Kappe besteht, die formschlüssig in jede Kammer des Hohlkörpers einsetzbare Stopfen aufweist, an denen mit Abstand eine den Querschnitt der jeweiligen Kammer ausfüllende Kolbenplatte befestigt ist und bei der der zwischen Kolbenplatte und Kappe befindliche Hohlraum mit einem dauerelastischen Füllmittel, vorzugsweise auf Kunststoffbasis ausgefüllt ist, wobei in der Kappe jeweils mindestens ein über die Kammertrennwand führender Überlaufkanal für das Füllmittel vorgesehen ist. Der Hohlkörper ist dabei als Rollladenprofil ausgebildet und soll zu einer Schwimmbadabdeckung zusammengefügt sein, die auf der Wasseroberfläche aufliegt.Another closure arrangement for covering open containers with a liquid therein is, for example, in FIG DE 195 08 953 C1 described. This hollow body made of metal or plastic with at least one axial chamber partition and a watertight closure, which consists of a cap provided with filling and venting openings, which has positively insertable plugs in each chamber of the hollow body, at which a distance filling the cross section of the respective chamber Piston plate is attached and in which the cavity located between the piston plate and cap is filled with a permanently elastic filler, preferably on a plastic basis, wherein in the cap at least one overflow channel leading over the chamber partition is provided for the filler. The hollow body is designed as a roller shutter profile and should be assembled to form a swimming pool cover that rests on the water surface.

Nachteilig hierbei ist, dass jede einzelne Hohlkammer eines Rollladenstabes mit einer eine spezielle Geometrie aufweisenden Abdichtvorrichtung zu versehen ist, die hier aus einer Kolbenplatte und einer dazwischen angeordneten dauerelastischen, von außen einzufüllenden Substanz besteht.The disadvantage here is that each individual hollow chamber of a roller shutter slat is to be provided with a sealing device which has a special geometry, which here consists of a piston plate and a permanently elastic substance to be filled in from the outside.

In dieser Ausführungsform ist eine derartige Schwimmbadabdeckung äußerst kostenintensiv in der Herstellung der Rollladenprofile und insbesondere in der Konfektion einzelner Rollladenstäbe, die an ihren beiden freien Enden flüssigkeitsdicht zu verschließen und zu einer Schwimmbadabdeckung zusammenzufügen sind.In this embodiment, such a swimming pool cover is extremely costly to manufacture the roller shutter profiles and in particular in the manufacture of individual roller shutter slats which are to be closed liquid-tight at their two free ends and to be joined together to form a swimming pool cover.

Weiterhin nachteilig bei den Lösungen im bekannten Stand der Technik ist die Tatsache, dass es bei bestimmungsgemäßer Verwendung der Schwimmbadabdeckungen nicht auszuschließen ist, dass bei einzelnen Rollladenstäben die abdichtenden Endkappen nicht vollumfänglich dicht sind und so die Hohlkammern einzelnen Rollladenstäbe mit Flüssigkeit gefüllt sind und die Schwimmbadabdeckung nicht mehr auf der Oberfläche schwimmt.Another disadvantage of the solutions in the known prior art is the fact that when the swimming pool covers are used as intended, it cannot be ruled out that the sealing end caps of individual roller shutter slats are not completely leakproof, and so the hollow chambers of individual roller shutter slats are filled with liquid and the swimming pool cover is not more floating on the surface.

Weiterhin ist offenbart, dass die Hohlkammer vollumfänglich mit einem Kern beispielsweise aus zellurarem Schaum ausgefüllt ist und dass das Basiselement eine von unten geöffnete Hohlkammer aufweist, in der ein Kern aus einem Schaumstoff so angeordnet ist, dass dieser nur an seinen Seitenflächen gehalten, mit der Flüssigkeit in Kontakt kommen kann. Das Basiselement dabei im Verfahren der Coextrusion hergestellt, d.h. sowohl das Basiselement als auch der Kern aus einem Schaumstoff werden gleichzeitig hergestellt und bestehen aus Werkstoffen mit unterschiedlichen Dichten.The FR 2747717 discloses a closure arrangement for covering open containers with a liquid therein, in particular for covering swimming pools, which comprises at least two base elements, the base element having at least one hollow chamber, at least one base element having one of its longitudinal sides with an opposite longitudinal side of an adjacent base element is movably connected at least in sections via at least one connecting means and has at least one connecting device on the longitudinal side opposite the longitudinal side connected to the connecting means, the hollow chamber of the base element having a material whose density is between 0.01 and 0.7 g / cm 3 is and at least one receiving opening receiving a fixing element is arranged on at least one connecting device of the base element.

The base element is produced in the coextrusion process, ie both the base element and the core are made of a foam and are made of materials with different densities.

Die US 4,577,352 A _zeigt ebenfalls eine Verschlussanordnung zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit. Hierbei sind die Basiselemente als Profile mit Hohlkammern ausgebildet, die über Verbindungsmittel miteinander drehbeweglich verbunden sind und dass in die Hohlkammern beispielsweise ein Element in die Hohlkammern einbringbar ist, welche aus einem Schaummaterial hergestellt ist bzw. aus einem elastischen Material, sodass es in die Hohlkammern hineingepresst, diese abdichtend verschließt. Es ist weiter offenbart, dass an den Stirnseiten der Basiselemente eine Verschlussanordnung so einbringbar ist, dass diese sowohl die Hohlkammern über die Dichtelemente als auch die Verbindungselemente des Basiselements über ein Fixierelement, welches an der Endkappe angeordnet ist, fixiert.The US 4,577,352 A _ also shows a closure arrangement for covering open containers with a liquid therein. Here, the base elements are designed as profiles with hollow chambers, which are rotatably connected to one another via connecting means and that, for example, an element can be introduced into the hollow chambers, which is made of a foam material or an elastic material, so that it is pressed into the hollow chambers , seals them tightly. It is further disclosed that a closure arrangement can be introduced on the end faces of the base elements in such a way that it fixes both the hollow chambers via the sealing elements and the connecting elements of the base element via a fixing element which is arranged on the end cap.

Die DE 2756738 A1 _offenbart ebenfalls eine Verschlussanordnung zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit, welche zumindest zwei Basiselemente aufweist, wobei das Basiselement wenigstens eine Hohlkammer aufweist, in der ein Streifen oder eine Leiste aus geschäumten Kunststoffmaterial mit geringerem spezifischem Gewicht eingebracht ist, die die Schwimmfähigkeit der Abdeckung auf dem Wasser sicherstellt und das an den freien Enden jedes Profilelements in dessen Enden einsteckbare Verschlussstopfen vorgesehen sind, die axiale Verstellbewegungen der Profilelemente verhindern sollen. Die Hohlkammer ist in diesem Beispiel als Ausnehmung ausgebildet, welche an der Unterseite der Profilelemente geöffnet ist.The DE 2756738 A1 Also disclosed is a closure arrangement for covering open containers with a liquid therein, which has at least two base elements, the base element having at least one hollow chamber in which a strip or a strip of foamed plastic material having a lower specific weight is introduced, which improves the buoyancy of the Ensures cover on the water and that plug-in plugs are provided at the free ends of each profile element in the ends, which are to prevent axial adjustment movements of the profile elements. In this example, the hollow chamber is designed as a recess which is open on the underside of the profile elements.

Die US2010/154110 A1 offenbart eine Verschlussanordnung zum Abdecken von offenen Behältern, welche zumindest zwei Basiselemente aufweist, die wiederum eine Hohlkammer aufweisen in der ein Schaumstoff angeordnet ist.The US2010 / 154110 A1 discloses a closure arrangement for covering open containers, which has at least two base elements, which in turn have a hollow chamber in which a foam is arranged.

Hier setzt die Erfindung ein, die sich die Aufgabe gestellt hat, die Nachteile des bekannten Standes der Technik zu überwinden und eine Verschlussanordnung zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit, insbesondere zum Abdecken von Schwimmbecken, aufzuzeigen, welche sowohl wirtschaftlich und kostengünstig herstellbar ist, als auch bei bestimmungsgemäßer Verwendung zum Abdecken von Schwimmbecken keine Undichtigkeiten der einzelnen Elemente aufweist und welche ein optisch ansprechendes Aussehen bei vollumfänglicher Funktionalität aufweist und die nahezu keine Flüssigkeit aufnimmt.This is where the invention comes in, which has the object of overcoming the disadvantages of the known prior art and of showing a closure arrangement for covering open containers with a liquid therein, in particular for covering swimming pools, which can be produced both economically and inexpensively is, as well as when used as intended for covering swimming pools has no leaks in the individual elements and which has a visually appealing appearance with full functionality and which absorbs almost no liquid.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.According to the invention, this object is achieved by the features of claim 1. Further advantageous configurations are described in the subclaims.

Es hat sich überraschend herausgestellt, dass eine Verschlussanordnung zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit, insbesondere zum Abdecken von Schwimmbecken, welche zumindest zwei Basiselemente umfasst, wobei das Basiselement eine Hohlkammer aufweist, wobei wenigstens ein Basiselement mit einer seiner Längsseiten mit einer dieser gegenüberliegenden Längsseite eines benachbarten Basiselements zumindest abschnittsweise beweglich über wenigstens ein Verbindungsmittel verbunden ist und an der, der mit dem Verbindungsmittel verbundenen Längsseite gegenüberliegenden Längsseite wenigstens eine Verbindungseinrichtung aufweist, die Hohlkammer des Basiselements einen Werkstoff aufweist, dessen Dichte zwischen 0,01 und 0,7 g / cm3 gemessen nach DIN 1183 beträgt, dass an wenigstens einer Verbindungseinrichtung des Basiselements wenigstens eine, ein Fixierelemente aufnehmende, Aufnahmeöffnung angeordnet ist, sich dadurch auszeichnet, dass der in der Hohlkammer des Basiselements angeordnete Werkstoff über wenigstens eine Distanzschicht von der die Hohlkammer umgebenden Wand beabstandet angeordnet ist. Die erfindungsgemäße Verschlussanordnung lässt sich somit in mehreren unterschiedlichen Farben, bedingt durch die Einfärbung der Distanzschicht und / oder des Basiselements wirtschaftlich und kostengünstig zur Verfügung stellen. Die erfindungsgemäße Verschlussanordnung weist somit gegenüber dem bisher bekannten Stand der Technik einen höheren Auftrieb bei ihrer bestimmungsgemäßen Verwendung auf und kann somit als kostengünstige und optisch ansprechende Verschlussanordnung für bereits verbaute, undichte Schwimmbadabdeckungen aus Hohlkammerprofilen mit seitlichen Dichtelementen eingesetzt werden.
Dabei hat es sich weiterhin als vorteilhaft herausgestellt, dass der in der Hohlkammer des Basiselementes angeordnete Werkstoff ausgewählt ist aus, vorzugsweise aus Polyvinylchlorid (PVC), Polyurethan (PU), Acrylnitril-Butadien-Styrol (ABS), Polystyrol (PS), Acrylester-Styrol-Acrylnitril (ASA), Polypropylen (PP), Polyethylen (PE), Polyethylenterephthalat (PET), Polycarbonat (PC), Polymethylmethacrylat (PMMA) oder deren Copolymeren bestehen. Neben der wirtschaftlichen und kostengünstigen Herstellung der die erfindungsgemäße Verschlussanordnung bildenden Basiselemente dadurch auch deren Schwimmfähigkeit gewährleistet.
Weiterhin vorteilhaft bei er erfindungsgemäßen Verschlussanordnung ist, dass einerseits eine gewisse Isolierwirkung für das unter der erfindungsgemäßen Verschlussanordnung befindliche, größtenteils erwärmte Flüssigkeiten, realisierbar ist und andererseits das bei extremen Witterungseinflüssen wie insbesondere Hagel die erfindungsgemäße Verschlussanordnung so ausgebildet ist, dass in den einzelnen Basiselementen keine Löcher durch ein Durchschlagen von Hagelkörnern realisierbar ist.
Ein weiterer Vorteil der erfindungsgemäßen Verschlussanordnung besteht insbesondere darin, dass diese überraschenderweise bei bestimmungsgemäßer Verwendung eine Wärmeleitfähigkeit von etwa 0,037 W / Km nach der HOT DISK Methode gemäß ISO 22007 aufweist.It has surprisingly been found that a closure arrangement for covering open containers with a liquid therein, in particular for covering swimming pools, which comprises at least two base elements, the base element having a hollow chamber, at least one base element having one of its longitudinal sides with one of these opposite longitudinal side of an adjacent base element is at least partially movably connected via at least one connecting means and on the longitudinal side opposite the longitudinal side connected to the connecting means has at least one connecting device, the hollow chamber of the base element has a material whose density is between 0.01 and 0.7 g / cm 3 measured according to DIN 1183 is that at least one receiving opening receiving a fixing element is arranged on at least one connecting device of the base element, characterized in that the Ohlkammer the base element arranged material is arranged at least a distance from the wall surrounding the hollow chamber spaced. The closure arrangement according to the invention can thus be made available in several different colors economically and inexpensively due to the coloring of the spacer layer and / or the base element. The closure arrangement according to the invention thus has a higher buoyancy when used as intended and can thus be used as a cost-effective and visually appealing closure arrangement for already installed, leaky swimming pool covers made of hollow chamber profiles with lateral sealing elements.
It has also proven to be advantageous that the material arranged in the hollow chamber of the base element is selected from, preferably polyvinyl chloride (PVC), polyurethane (PU), acrylonitrile-butadiene-styrene (ABS), polystyrene (PS), acrylic ester Styrene-acrylonitrile (ASA), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polycarbonate (PC), polymethyl methacrylate (PMMA) or their copolymers. In addition to the economical and inexpensive manufacture of the base elements forming the closure arrangement according to the invention, this also ensures their floatability.
A further advantage of the closure arrangement according to the invention is that, on the one hand, a certain insulating effect can be achieved for the largely heated liquids located under the closure arrangement according to the invention, and on the other hand that extreme weather influences such as hail in particular, the closure arrangement according to the invention is designed such that no holes can be realized in the individual base elements by hailstones breaking through.
Another advantage of the closure arrangement according to the invention is in particular that, surprisingly, when used as intended, it has a thermal conductivity of about 0.037 W / km according to the HOT DISK method according to ISO 22007.

Die erfindungsgemäße Verschlussanordnung kann dabei so ausgebildet sein, dass der Werkstoff des Basiselements über seine Dicke für sichtbares Licht einen Transmissionsgrad von mindestens 80 % gemessen nach ISO 13468-2 aufweist. Der in der Hohlkammer des Basiselements angeordnete Werkstoff kann dabei eine dunkle Farbe, insbesondere Schwarz aufweisen.The closure arrangement according to the invention can be designed in such a way that the material of the base element has a transmittance of at least 80% measured according to ISO 13468-2 over its thickness for visible light. The material arranged in the hollow chamber of the base element can have a dark color, in particular black.

Dabei hat es sich als vorteilhaft erwiesen, dass die Aufnahmeöffnung der Verbindungseinrichtung etwa parallel zur Längsseite des Basiselements angeordnet ist. Hierdurch ist eine wirtschaftliche und kostengünstige Herstellung der die Verschlussanordnung bildenden Basiselemente möglich.It has proven advantageous that the receiving opening of the connecting device is arranged approximately parallel to the long side of the base element. This enables an economical and inexpensive manufacture of the base elements forming the closure arrangement.

Es hat sich ebenfalls als vorteilhaft herausgestellt, dass die Aufnahmeöffnung der Verbindungseinrichtung gegenüber der Hohlkammer des Basiselements angeordnet ist. Hierdurch kann eine erfindungsgemäße Verschlussanordnung zur Verfügung gestellt werden, bei der die die erfindungsgemäße Verschlussanordnung bildenden Basiselemente gegen mögliche Längsverschiebungen gegeneinander gesichert sind.It has also turned out to be advantageous that the receiving opening of the connecting device is arranged opposite the hollow chamber of the base element. As a result, a closure arrangement according to the invention can be provided in which the base elements forming the closure arrangement according to the invention are secured against possible longitudinal displacements.

Eine ebenfalls vorteilhafte Ausführungsform der erfindungsgemäßen Verschlussanordnung ist so ausgebildet, dass die Aufnahmeöffnung der Verbindungseinrichtung etwa gegenüber der Aufnahmeöffnung des Basiselements angeordnet ist. Dies hat den Vorteil, dass die verbundenen Basiselemente zumindest partiell überdeckt werden und diese ebenso gegen ein Verschieben gegeneinander gesichert sind.A likewise advantageous embodiment of the closure arrangement according to the invention is designed such that the receiving opening of the connecting device is arranged approximately opposite the receiving opening of the base element. This has the advantage that the connected base elements are at least partially covered and that they are also secured against displacement against one another.

Weiterhin vorteilhaft bei der erfindungsgemäßen Verschlussanordnung ist, dass das Fixierelement kraftschlüssig und / oder stoffschlüssig mit dem Basiselement verbunden ist. Hierdurch kann eine erfindungsgemäße Verschlussanordnung zur Verfügung gestellt werden, die sich sehr schnell und einfach den unterschiedlichen Geometrien von Schwimmbädern vor Ort anpassen lässt und bei der die Montage der einzelnen Basiselemente zu einer erfindungsgemäßen Verschlussanordnung und deren Fixierung, insbesondere gegen mögliche Längsverschiebungen einfach und werkzeuglos möglich ist. Ein weiterer Vorteil besteht darin, dass bei einer kraftschlüssigen Verbindung eine Austauschbarkeit einzelner Basiselemente insbesondere bei Beschädigungen problemlos möglich ist.Another advantage of the closure arrangement according to the invention is that the fixing element is connected to the base element in a force-locking and / or material-locking manner. As a result, a closure arrangement according to the invention can be made available which can be adapted very quickly and easily to the different geometries of swimming pools on site and in which the assembly of the individual basic elements to form a closure arrangement according to the invention and its fixing, in particular against possible longitudinal displacements, is possible in a simple and tool-free manner . Another advantage is that in the case of a non-positive connection, individual base elements can be exchanged without any problems, particularly in the event of damage.

Es liegt jedoch auch im Rahmen der Erfindung, dass die erfindungsgemäße Verschlussanordnung bei erhöhten Anforderungen an die Stabilität oder durch bestimmte nationale Sicherheitsvorschriften so ausgebildet ist, dass das Fixierelement über an sich bekannte Klebstoffsysteme stoffschlüssig mit dem Basiselement verbunden ist.However, it is also within the scope of the invention that the closure arrangement according to the invention, in the case of increased requirements for stability or certain national safety regulations, is designed such that the fixing element is integrally connected to the base element via known adhesive systems.

Dabei hat es sich weiterhin vorteilhaft herausgestellt, dass das Fixierelement eine Basis und wenigstens ein Einsteckelement aufweist. Ein derartiges Fixierelement lässt sich ebenfalls kostengünstig und wirtschaftlich herstellen, bspw. im Spritzgießverfahren aber auch im sogenannten 3D- Druck.It has also been found to be advantageous that the fixing element has a base and at least one insertion element. Such a fixing element can also be produced inexpensively and economically, for example in the injection molding process but also in so-called 3D printing.

Ein weiterer Vorteil der erfindungsgemäßen Verschlussanordnung besteht darin, dass das Einsteckelement des Fixierelementes in Wirkverbindung mit der Aufnahmeöffnung der Basiselemente steht. Bei der erfindungsgemäßen Verschlussanordnung ist das Einsteckelement so ausgebildet, dass es mit geringem Kraftaufwand und werkzeuglos aus einzelnen Basiselementen zu einer erfindungsgemäßen Verschlussanordnung montierbar ist.Another advantage of the closure arrangement according to the invention is that the insertion element of the fixing element is in operative connection with the receiving opening of the base elements. In the case of the closure arrangement according to the invention, the insertion element is designed such that it can be assembled from individual base elements to form a closure arrangement according to the invention with little effort and without tools.

Die erfindungsgemäße Verschlussanordnung ist in vorteilhafter Weise auch so ausgebildet, dass das Fixierelement an seiner Basis wenigstens ein Abstützelement aufweist. Dieses Abstützelement des Fixierelementes ist dabei so ausgebildet, dass es bei der Montage über das Einsteckelement in der Aufnahmeöffnung der Basiselemente bei bestimmungsgemäßer Verwendung der erfindungsgemäßen Verschlussanordnung zu einer weiteren und besseren sowie lagerichtigen Befestigung des Fixierelementes im Basiselement und zu einer Verdrehsicherheit führt. Die Basis des Fixierelementes ist dabei vorteilhafterweise so ausgebildet, dass sie eine Grundfläche aufweist, welche in etwa der Grundfläche des Basisprofils entspricht.The closure arrangement according to the invention is also advantageously designed such that the fixing element has at least one support element at its base. This support element of the fixing element is designed such that it leads to a further and better and correct fixing of the fixing element in the base element and to a security against rotation when installed via the insertion element in the receiving opening of the base elements when the locking arrangement according to the invention is used as intended. The base of the fixing element is advantageously designed such that it has a base area which corresponds approximately to the base area of the base profile.

Dabei hat es sich weiterhin als vorteilhaft herausgestellt, dass die Basiselemente aus einem polymeren Werkstoff, vorzugsweise aus Polyvinylchlorid (PVC), Polyurethan (PU), Acrylnitril-Butadien-Styrol (ABS), Polystyrol (PS), Acrylester-Styrol-Acrylnitril (ASA), Polypropylen (PP), Polyethylen (PE), Polyethylenterephthalat (PET), Polycarbonat (PC), Polymethylmethacrylat (PMMA) oder deren Copolymeren bestehen. Neben der wirtschaftlichen und kostengünstigen Herstellung der die erfindungsgemäße Verschlussanordnung bildenden Basiselemente ist neben der Schwimmfähigkeit der polymeren Werkstoffe auch noch die Korrosionsfreiheit als Vorteil zu benennen.It has also proven to be advantageous that the base elements made of a polymeric material, preferably polyvinyl chloride (PVC), polyurethane (PU), acrylonitrile-butadiene-styrene (ABS), polystyrene (PS), acrylic ester-styrene-acrylonitrile (ASA ), Polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polycarbonate (PC), polymethyl methacrylate (PMMA) or their copolymers. In addition to the economical and cost-effective production of the base elements forming the closure arrangement according to the invention, in addition to the floatability of the polymeric materials, the freedom from corrosion should also be mentioned as an advantage.

Die Basiselemente der erfindungsgemäßen Verschlussanordnung sind so ausgebildet, dass sie eine Wanddicke im Bereich von etwa 0,05 bis 5,0 mm, vorzugsweise 0,1 bis 2,5 mm aufweisen. Hierdurch kann vorteilhafterweise eine wirtschaftliche und kostengünstige Fertigung der die erfindungsgemäße Verschlussanordnung bildenden Basiselemente realisiert werden.The base elements of the closure arrangement according to the invention are designed such that they have a wall thickness in the range from approximately 0.05 to 5.0 mm, preferably 0.1 to 2.5 mm. As a result, the base elements forming the closure arrangement according to the invention can advantageously be produced economically and inexpensively.

Die erfindungsgemäße Verschlussanordnung zeichnet sich weiterhin dadurch aus, dass das Basiselement im Querschnitt etwa mehreckig, prismatisch, rund, oval, elliptisch und dergleichen ausgebildet ist. In dieser vorteilhaften Ausgestaltung der erfindungsgemäßen Verschlussanordnung sind verschiedenste, wirtschaftlich und kostengünstig herstellbare, die erfindungsgemäße Verschlussanordnung bildende, Basiselemente zur Verfügung stellbar.The closure arrangement according to the invention is further characterized in that the base element is approximately polygonal, prismatic, round, oval, elliptical and the like in cross section. In this advantageous embodiment of the closure arrangement according to the invention, a wide variety of basic elements which form the closure arrangement according to the invention can be made available economically and inexpensively.

Ein weiterer Vorteil der erfindungsgemäßen Verschlussanordnung besteht darin, dass der in der Hohlkammer des Basiselements angeordnete Werkstoff über die Distanzschicht selbst mit der die Hohlkammer umgebenden Wand stoffschlüssig angeordnet ist. Hierbei kann die Distanzschicht als an sich bekanntes Klebstoffsystem ausgebildet sein.
Der Werkstoff der Distanzschicht ist dabei ausgewählt aus der Gruppe der Polyamide (PA); der Polyurethane (PUR), der Polyolefine, insbesondere Polyethylen (PE); der amorphen Polyalphaolefine (APAO); der Styren- bzw., Styren- Buthylen Copolymere; der thermoplastischen Elastomere (TPE), insbesondere der thermoplastischen Elastomere auf Urethan-Basis (TPE-U), der thermoplastischen Copolyamide (TPE-A), der thermoplastischen Polyester-Elastomere (TPE-E); der Ethylenvinylacetat-Copolymere (EVAC) und dergleichen.Another advantage of the closure arrangement according to the invention is that the material arranged in the hollow chamber of the base element is arranged cohesively over the spacer layer itself with the wall surrounding the hollow chamber. Here, the spacer layer can be designed as an adhesive system known per se.
The material of the spacer layer is selected from the group of polyamides (PA); polyurethanes (PUR), polyolefins, especially polyethylene (PE); amorphous polyalphaolefins (APAO); the styrene or, styrene-butylene copolymers; the thermoplastic elastomers (TPE), in particular the thermoplastic elastomers based on urethane (TPE-U), the thermoplastic copolyamides (TPE-A), the thermoplastic polyester elastomers (TPE-E); of ethylene vinyl acetate copolymers (EVAC) and the like.

Es hat sich als vorteilhaft bei der erfindungsgemäßen Verschlussanordnung weiterhin herausgestellt, dass die Distanzschicht eine Dicke von etwa 0,05 mm bis etwa 5 mm, vorzugsweise 0,05 bis etwa 1,5 mm aufweist.It has also been found to be advantageous in the closure arrangement according to the invention that the spacer layer has a thickness of approximately 0.05 mm to approximately 5 mm, preferably 0.05 to approximately 1.5 mm.

In einer ebenfalls vorteilhaften Ausgestaltung der erfindungsgemäßen Verschlussanordnung weist wenigstens ein Basiselement wenigstens ein Lichtelement wie beispielsweise LED-Leuchten und dergleichen auf, welche der erfindungsgemäßen Verschlussanordnung ein optisch ansprechendes Design sowie zusätzliche Funktionalitäten verleihen. Diese Lichtelemente können dabei sowohl im Herstellungsprozess der die erfindungsgemäße Verschlussanordnung bildenden Basiselemente mit eingebracht werden, als auch nachträglich schnell und einfach an der Verschlussanordnung angebracht werden.In a likewise advantageous embodiment of the closure arrangement according to the invention, at least one base element has at least one light element such as LED lights and the like, which give the closure arrangement according to the invention an optically appealing design and additional functionalities. These light elements can both be incorporated in the manufacturing process of the base elements forming the closure arrangement according to the invention, and can also be subsequently and quickly attached to the closure arrangement.

Es liegt jedoch auch im Rahmen der Erfindung bei der erfindungsgemäßen Verschlussanordnung, dass wenigstens ein Basiselement wenigstens ein Sensorelement aufweist, wie beispielsweise Temperaturmesssensoren, Lichtsensoren, Wasserzusammensetzungssensoren, Längenmesssensoren, Lagepositionssensoren, Entfernungssensoren und dergleichen, welche der erfindungsgemäßen Verschlussanordnung neue Funktionalitäten verleihen, ohne das deren bestimmungsgemäße Verwendung insgesamt eingeschränkt bzw. reduziert ist.
Diese Sensorelemente können dabei einerseits im Herstellungsprozess der die erfindungsgemäße Verschlussanordnung bildenden Basiselemente eingebracht bzw. angebracht werden, andererseits ist es aber auch möglich, diese nachträglich in die erfindungsgemäße Verschlussanordnung zu integrieren.However, it is also within the scope of the invention for the closure arrangement according to the invention that at least one base element has at least one sensor element, such as, for example, temperature measurement sensors, light sensors, water composition sensors, length measurement sensors, position sensors, distance sensors and the like, which give the closure arrangement according to the invention new functionalities without the intended use thereof Overall use is restricted or reduced.

In Fig. 1 ist eine perspektivische Detaildarstellung einer erfindungsgemäßen Verschlussanordnung 1 zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit, insbesondere zum Abdecken von Schwimmbecken dargestellt.In Fig. 1 is a perspective detailed view of a closure arrangement 1 according to the invention for covering open containers with a liquid therein, in particular for covering swimming pools.

Die erfindungsgemäße Verschlussanordnung 1 umfasst mehrere Basiselemente 2, wobei jedes Basiselement 2 eine Hohlkammer 5 aufweist, wobei jedes Basiselement 2 mit einer seiner Längsseiten 21, 22 mit einer dieser gegenüberliegenden Längsseite 21, 22 eines benachbarten Basiselements 2 zumindest abschnittsweise beweglich über wenigstens ein Verbindungsmittel 3 verbunden ist und an der, der mit dem Verbindungsmittel 3 verbundenen Längsseite 21 gegenüberliegenden, Längsseite 22 wenigstens eine Verbindungseinrichtung 4 aufweist.The closure arrangement 1 according to the invention comprises a plurality of base elements 2, each base element 2 having a hollow chamber 5, each base element 2 being connected to one of its longitudinal sides 21, 22 with an opposite longitudinal side 21, 22 of an adjacent base element 2 so as to be movable at least in sections via at least one connecting means 3 and on which the longitudinal side 22 opposite the longitudinal side 21 connected to the connecting means 3 has at least one connecting device 4.

It can thus advantageously be avoided that the free ends of the base elements 2 of the closure arrangement 1 according to the invention come into direct contact with the edge of the swimming pool, for example.

In der Fig. 2 ist eine perspektivische Detaildarstellung einer erfindungsgemäßen Verschlussanordnung 1 zum Abdecken von offenen Behältern mit einer darin befindlichen Flüssigkeit, insbesondere zum Abdecken von Schwimmbecken dargestellt.In the Fig. 2 is a perspective detailed view of a closure arrangement 1 according to the invention for covering open containers with a liquid therein, in particular for covering swimming pools.
