    • Der Abschnitt des Kunststoffelements nach Figur 1 zeigt in der Vertikalen die Gesamtabmessung des ganzen Elementes mit dem Aussenrahmen 1 und der Skelettstruktur 2, in einer Ansicht 3 von unten auf das Element, und in einer Draufsicht 4 auf das Element. Das Element ist in sich elastisch nachgiebig, plattenförmig und rechteckig. In der Praxis wird das Element meist quadratisch ausgebildet, so dass es also in Figur 1 in der Horizontalen die gleiche Abmessung hat wie in der dargestellten Vertikalen. Die Skelettstruktur 2 umfasst gitterförmige Verstrebungen, die als Rippen 5, 6 und 7 vorliegen. Eine Vielzahl solcher Elemente dient zum Bilden eines Bodenbelages, z.B. zum Tennisspielen. Zur Erhöhung der Rutschfestigkeit werden die Rippen 5-7 auf der Oberseite mit Riffelungen 8 versehen, wie in Figur 2 teilweise dargestellt ist.The section of the plastic element after Figure 1 shows the total dimension of the vertical whole element with the outer frame 1 and the skeleton structure 2, in a view 3 from below of the element, and in a top view 4 of the element. The element is resilient, plate-shaped and flexible rectangular. In practice, the element is usually square trained so that it is in Figure 1 in the Horizontal has the same dimension as in the shown Vertical. The skeleton structure 2 comprises lattice-like struts that act as ribs 5, 6 and 7 available. A variety of such elements are used for Forming a floor covering, e.g. For playing tennis. For To increase the slip resistance, the ribs 5-7 are on provide the top with corrugations 8, as in FIG. 2 is partially shown.

    Zum Verlegen der Kunststoffelemente sind diese mit zusammenwirkenden Kupplungsorganen für angrenzende Elemente versehen. Diese kann man in männliche und weibliche Kupplungsorgane unterteilen. Aus Figur 1 ist ersichtlich, dass die eine Elementseite drei männliche Kupplungsorgane 9 aufweist. Eine benachbarte Seite des Elements weist ebenfalls drei männliche Kupplungsorgane 9 auf, wobei in Figur 1 aber nur eines dargestellt ist. Das männliche Kupplungsorgan 9 ist als länglicher Riegel ausgebildet, der sich parallel zur Elementenebene erstreckt und vom Aussenrahmen 1 abragt. Der Riegel 9 hat an seinem vom Aussenrahmen 1 abgewandten Ende eine Platte 10, die in später erläuterter Weise als Anschlag dient. Aus den Figuren 4-6 ist ersichtlich, dass der Riegel 9 im Querschnitt ein T-Profil mit Steg 11 und Balken 12 hat.These are for laying the plastic elements with interacting coupling elements for adjacent Elements. These can be divided into male and female Divide the coupling elements. From Figure 1 it can be seen that one element side three male Coupling members 9 has. An adjacent side of the Elements also has three male coupling elements 9 on, but only one is shown in Figure 1. The male coupling member 9 is designed as an elongated bar, which extends parallel to the element plane and protrudes from the outer frame 1. The bolt 9 has on his End facing away from the outer frame 1 is a plate 10 which serves as a stop in a manner explained later. From the Figures 4-6 it can be seen that the bolt 9 in cross section has a T-profile with web 11 and beam 12.

    Jedes weibliche Kupplungsorgan kann mit dem männlichen Kupplungsorgan 9 in formschlüssigen Eingriff gebracht werden. Es sind also pro Kunststoffelement gleich viel weibliche und männliche Kupplungsorgane vorhanden. Die weiblichen Kupplungsorgane sind an den übrigen beiden benachbarten Seiten des Kunststoffelementes vorhanden, wobei jedes weibliche Kupplungsorgan 13 zwei federelastische Klinken 14 und 15 aufweist. Aus den Figuren 1, 2 und 3 ist ersichtlich, dass die weiblichen Kupplungsorgane 13 innerhalb des Aussenrahmens 1 liegen. Die beiden Klinken 14 und 15 eines weiblichen Kupplungsorgans 13 sind mit je einer Abstützschulter 16 und 17 für den zwischenliegenden Riegel 9 versehen (Figur 5), und beide Abstützschultern 16, 17 sind einander zugewandt (Figur 4-6). Im gekuppelten Zustand zweier benachbarter Kunststoffelemente hintergreifen die federelastischen Klinken 14 und 15 den Riegel 9 auf der Elementenunterseite 3, und zwar rechtwinklig zur Elementenebene (Figur 5).Any female coupling organ can with the male coupling member 9 in positive engagement to be brought. So there are per plastic element the same number of female and male coupling organs available. The female coupling organs are on the rest two adjacent sides of the plastic element present, each female coupling member 13 two has resilient pawls 14 and 15. From the figures 1, 2 and 3 it can be seen that the female coupling organs 13 lie within the outer frame 1. The two pawls 14 and 15 of a female coupling member 13 are each with a support shoulder 16 and 17 for the intermediate latch 9 provided (Figure 5), and both Support shoulders 16, 17 face each other (Figure 4-6). In the coupled state of two neighboring plastic elements reach behind the resilient pawls 14 and 15 the bolt 9 on the underside of the element 3, and at right angles to the element level (Figure 5).

    Aus den Figuren 1-3 ist ersichtlich, dass zwischen je zwei männlichen Kupplungsorganen 9 eine Feder 18 liegt. Die Feder 18 ist als Blattfeder ausgebildet und stützt sich mit beiden Enden am Aussenrahmen 1 ab und ist mit diesem einstückig, besteht also auch aus dem Kunststoffmaterial. Aus Figur 1 ist ersichtlich, dass jede Seite des Kunststoffelementes, welche die drei männlichen Kupplungsorgane 9 aufweist, zwei dazwischenliegende Federn 18 hat. Das gleiche gilt auch für die andere, in Figur 1 untere horizontale Seite des Elementes. Diese zwei Federn 18 pro Seite haben die Aufgabe, zwei an dieser Seite miteinander gekuppelte Kunststoffelemente auseinanderzudrücken, damit eine Dehnungsfuge zwischen benachbarten Elementen entsteht, damit auch bei hohen Temperaturen kein Stauchen der verlegten Kunststoffelemente entsteht. Aus den Figuren 1-3 ist ersichtlich, dass die Unterseite des Elementes mit Stegen 19 versehen ist, wobei jeder Steg 19 eine Auflaufschräge 20 aufweist. Der Steg 19 mit Auflaufschräge 20 liegt wie die weiblichen Kupplungsorgane 13 innerhalb der Elementenebene, und zwar immer zwischen zwei weiblichen Kupplungsorganen 13. Werden zwei benachbarte Elemente miteinander gekuppelt, und zwar von der Stellung nach Figur 4 in die Stellung nach Figur 5, so drückt die Auflaufschräge 20 auf den mittleren Bereich der Feder 18 und verformt sie in die Stellung 18', wie es in Figur 1 bei einer Feder strichpunktiert gezeigt ist. Hierdurch werden beide gekuppelten Kunststoffelemente so weit auseinandergedrückt, dass die Klinken 14, 15 der weiblichen Kupplungsorgane 13 am Anschlag 10 der männlichen Kupplungsorgane 9 federelastisch anliegen. Sind zwei benachbarte Kunststoffelemente so miteinander verbunden worden, liegt nicht mehr die Auflaufschräge 20 an der Feder in ihrer Stellung 18' an, sondern eine an die Auflaufschräge 20 anschliessende Kante 21.It can be seen from FIGS. 1-3 that a spring between two male coupling elements 9 18 lies. The spring 18 is designed as a leaf spring and is supported with both ends on the outer frame 1 and is in one piece with it, so it also consists of the plastic material. From Figure 1 it can be seen that each Side of the plastic element, which the three male Coupling members 9 has two springs in between 18 has. The same goes for the other one, in Figure 1 lower horizontal side of the element. This two springs 18 per side have the task of two on this Push apart the coupled plastic elements, thus an expansion joint between neighboring elements, so even at high Temperatures do not compress the installed plastic elements arises. It can be seen from FIGS. 1-3 that the underside of the element is provided with webs 19, wherein each web 19 has a run-up slope 20. The Web 19 with ramp 20 lies like the female Coupling members 13 within the element level, namely always between two female coupling organs 13. Be two adjacent elements coupled together, and from the position shown in Figure 4 to the position after Figure 5, the ramp 20 presses on the middle Area of the spring 18 and deformed it into position 18 ', as is dash-dotted in FIG. 1 for a spring is shown. As a result, both coupled plastic elements so far apart that the latches 14, 15 of the female coupling members 13 at the stop 10 of the male coupling members 9 resiliently. Are two adjacent plastic elements so together connected, the run-up slope no longer lies 20 on the spring in its position 18 ', but an edge 21 adjoining the ramp 20.

    Das ganze erläuterte Kunststoffelement ist einstückig.The whole plastic element is explained in one piece.

    Bei einem anderen, nicht dargestellten Ausführungsbeispiel könnten die Federn 18 auf den anderen beiden Seiten des Kunststoffelementes liegen, dort wo sich die weiblichen Kupplungsorgane 13 befinden, so dass sich dann also zwischen je zwei weiblichen Kupplungsorganen 13 eine Feder 18 befindet.In another embodiment, not shown could the springs 18 on top of each other both sides of the plastic element, where are the female coupling members 13, so that between two female coupling organs 13 a spring 18 is located.

    Das Zusammensetzen einer Vielzahl von Kunststoffelementen zum Bilden des Bodenbelages erfolgt so: Ein Kunststoffelement wird auf eine Unterlage gelegt, so dass die in Figur 3 gezeigten Flächen 22 auf der Unterlage anliegen (Figur 3, 4). Das benachbarte Kunststoffelement wird dann mit seinem weiblichen Kupplungsorgan 13 in die Stellung nach Figur 4 gebracht und nach unten gedrückt, so dass die beiden federelastischen Klinken 14, 15 zuerst aufgeweitet werden und dann in die Stellung nach Figur 5 einschnappen und den Riegel 9 hintergreifen. Auf diese Weise werden die männlichen und weiblichen Kupplungsorgane benachbarter Kunststoffelemente miteinander verbunden. Durch die Federn 18 liegen die Klinken 14, 15 an den Stirnplatten 10 an, so dass sich zwischen benachbarten Kunststoffelementen ein Abstand von wenigen Millimetern ergibt. Hierdurch müssen beim Verlegen der Kunststoffelemente diese nicht mehr auseinandergezogen werden, um eine Dehnungsfuge zu ergeben. Ist der ganze Bodenbelag verlegt worden, so werden die innerhalb der Ebene des Bodenbelages auftretenden horizontalen Belastungen von den horizontal liegenden Riegeln 9 mit ihren Stirnplatten 10 aufgenommen, so dass die männlichen Kupplungsorgane 9 nur auf Zug belastet werden, aber nicht mehr auf Biegung, wie beim eingangs genannten bekannten Kunststoffelement. Aus den Figuren ist ersichtlich, dass das Kunststoffelement keine rohrförmigen Strukturen mehr aufweist wie beim bekannten Kunststoffelement, so dass sich nunmehr kein Schmutz in den rohrförmigen Strukturen ablagern kann. Besonders aus Figur 3 ist ersichtlich, dass die Struktur der Unterseite des Kunststoffelementes nur Aussenflächen aufweist, so dass nach einem Regen durch die umströmende Luft die Feuchtigkeit verhältnismässig schnell weggeführt werden kann. Das bedeutet, dass der Bodenbelag aus den erfindungsgemässen Kunststoffelementen nach einem Regen schneller trocken wird.Assembling a variety of plastic elements To form the floor covering: A plastic element is placed on a base, so that the surfaces 22 shown in Figure 3 on the base (Figure 3, 4). The neighboring plastic element is then with its female coupling member 13th brought into the position according to FIG. 4 and pressed down, so that the two resilient pawls 14, 15 first be expanded and then in the position snap in according to Figure 5 and reach behind the bolt 9. This way the male and female Coupling elements of adjacent plastic elements with each other connected. The pawls 14 are located by the springs 18, 15 on the end plates 10, so that between adjacent Plastic elements a distance of a few Millimeters results. As a result, when laying the Plastic elements no longer pulled them apart to create an expansion joint. Is the whole Flooring has been laid, so those within the Level of the flooring occurring horizontal loads of the horizontal bars 9 with their End plates 10 added so that the male coupling organs 9 can only be loaded on a train, but not more on bending, as in the known at the beginning Plastic element. It can be seen from the figures that the plastic element no longer has any tubular structures has as in the known plastic element, so that there is now no dirt in the tubular structures can deposit. It can be seen particularly from FIG. 3 that that the structure of the bottom of the plastic element only has outside surfaces, so after a rain due to the air flowing around, the humidity is proportional can be carried away quickly. It means that the floor covering made of the plastic elements according to the invention dries faster after rain.

    Durch das formschlüssige Hintergreifen der Klinken 14, 15 am Riegel 9 nach Figur 5 wird ein einseitiges Aufstellen eines Kunststoffelementes verhindert, so dass der Bodenbelag ganz eben bleibt. Fall ein Demontieren des Bodenbelages erfolgen soll, wird ein elastisch nachgiebiges Kunststoffelement gemäss Figur 6 einseitig nach oben gedrückt, so dass die Klinke 15 ausser Eingriff mit dem Riegel 9 des benachbarten Kunststoffelementes kommt. Dann gelangt der ganze Riegel 9 ausser Eingriff mit den Klinken 14 und 15.Due to the positive engagement of the Pawls 14, 15 on the bolt 9 according to FIG. 5 become one-sided Prevents a plastic element from being set up, so that the flooring stays completely level. Case disassembly of the floor covering is to be elastic flexible plastic element according to FIG. 6 one-sided pushed upwards so that the pawl 15 is disengaged with the bolt 9 of the adjacent plastic element is coming. Then the whole bolt 9 comes out of engagement with the pawls 14 and 15.
