Abstract

The plastics element has male coupling members (9) which project from the outer frame (1) as elongated bars parallel to the plane of the element. Each female coupling element (13) lying within the outer frame has two spring-elastic catches (14,15) which grip behind the bar (9). The elongated bar has a stop (10) for the two catches. The stop is made as a plate which protrudes over the face side of the bar.

Description

Die Erfindung betrifft ein elastisch nachgiebiges, plattenförmiges und rechteckiges Kunststoffelement, zum Bilden eines Bodenbelages aus einer Vielzahl solcher Elemente, wobei das Element eine Skelettstruktur mit einem Aussenrahmen und damit aus einem Stück bestehende gitterförmige Verstrebungen sowie Kupplungsorgane für angrenzende Elemente aufweist, und wobei die Kupplungsorgane des Elementes männliche und damit zusammenwirkende weibliche Kupplungsorgane umfasst.The invention relates to an elastically resilient, plate-shaped and rectangular plastic element for forming a floor covering from a plurality of such elements, the element having a skeleton structure with an outer frame and thus one-piece lattice-like struts and coupling elements for adjacent elements, and wherein the coupling elements of the Element includes male and interacting female coupling organs.

Ein solches Kunststoffelement ist durch die CH-PS 649 798 bekannt. Dieses an sich bewährte Kunststoffelement soll noch in verschwiedener Hinsicht verbessert werden. So sollen insbesondere die Kupplungsorgane so ausgebildet werden, dass das Kuppeln aber auch das Entkuppeln benachbarter Elemente leicht von statten geht; gekuppelte Elemente aber ganz plan liegen, sich also nicht einseitig aufstellen können, und wobei diese plane Lage auch bei grossen Temperaturunterschieden gewährleistet ist.Such a plastic element is known from CH-PS 649 798. This tried and tested plastic element is to be improved in various ways. In particular, the coupling members should be designed so that the coupling but also the uncoupling of neighboring elements is easy; coupled elements, however, lie completely flat, so they cannot stand on one side, and this flat position is guaranteed even with large temperature differences.

Das erfindungsgemässe Kunststoffelement ist dadurch gekennzeichnet, dass jedes männliche Kupplungsorgan als länglicher Riegel parallel zur Elementenebene vom Aussenrahmen abragt und jedes innerhalb des Aussenrahmens liegende weibliche Kupplungsorgan zwei federelastische Klinken aufweist, die den Riegel rechtwinklig zur Elementenebene auf der Elementenunterseite hintergreifen, und dass der längliche Riegel an seinem vom Aussenrahmen abgewandten Ende einen Anschlag für die beiden Klinken aufweist.The plastic element according to the invention is characterized in that each male coupling element protrudes from the outer frame as an elongate bolt parallel to the element plane and each female coupling element lying within the outer frame has two spring-elastic latches which engage behind the bolt at right angles to the element plane on the underside of the element, and that the elongate bolt is on its end facing away from the outer frame has a stop for the two pawls.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigen:

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 according to FIG. 1 shows in the vertical the overall dimension of the entire 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 inherently resilient, plate-shaped and rectangular. In practice, the element is usually designed to be square, so that in Figure 1 it has the same dimension in the horizontal as in the vertical shown. The skeletal structure 2 comprises lattice-like struts, which are present as ribs 5, 6 and 7. A variety of such elements are used to form a floor covering, e.g. For playing tennis. To increase the slip resistance, the ribs 5-7 are provided with corrugations 8 on the upper side, as is partially shown in FIG.

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.To lay the plastic elements, they are provided with interacting coupling elements for adjacent elements. These can be divided into male and female coupling organs. It can be seen from FIG. 1 that one element side has three male coupling elements 9. An adjacent side of the element also has three male coupling members 9 on, but only one is shown in Figure 1. The male coupling member 9 is designed as an elongated bolt which extends parallel to the element plane and protrudes from the outer frame 1. The bolt 9 has at its end facing away from the outer frame 1 a plate 10, which serves as a stop in a manner explained later. It can be seen from FIGS. 4-6 that the crossbar 9 has a T-profile with a web 11 and a beam 12 in cross section.

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).Each female coupling member can be brought into positive engagement with the male coupling member 9. There are therefore the same number of female and male coupling elements per plastic element. The female coupling elements are provided on the remaining two adjacent sides of the plastic element, each female coupling element 13 having two spring-elastic pawls 14 and 15. It can be seen from FIGS. 1, 2 and 3 that the female coupling members 13 lie within the outer frame 1. The two pawls 14 and 15 of a female coupling member 13 are each provided with a support shoulder 16 and 17 for the intermediate bolt 9 (Figure 5), and both support shoulders 16, 17 face each other (Figure 4-6). In the coupled state of two adjacent plastic elements, the resilient pawls 14 and 15 engage behind the bolt 9 on the underside 3 of the element, at right angles to the element plane (FIG. 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 18 lies between each two male coupling elements 9. 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. It can be seen from FIG. 1 that each side of the plastic element, which has the three male coupling elements 9, has two springs 18 located in between. The same also applies to the other horizontal side of the element, which is lower in FIG. 1. These two springs 18 on each side have the task of two on this Push the side of the coupled plastic elements apart so that there is an expansion joint between adjacent elements so that the installed plastic elements are not compressed even at high temperatures. It can be seen from FIGS. 1-3 that the underside of the element is provided with webs 19, each web 19 having a run-up slope 20. The web 19 with ramp 20 lies like the female coupling elements 13 within the element plane, and always between two female coupling elements 13. If two adjacent elements are coupled to one another, namely from the position according to FIG. 4 to the position according to FIG Run-up slope 20 onto the central area of the spring 18 and deforms it into the position 18 ', as is shown in dash-dot lines in FIG. 1 for a spring. As a result, the two coupled plastic elements are pressed apart so far that the pawls 14, 15 of the female coupling members 13 rest resiliently on the stop 10 of the male coupling members 9. If two adjacent plastic elements have been connected to one another in this way, the run-up slope 20 no longer bears against the spring in its position 18 ', but an edge 21 adjoining the run-up slope 20.

Das ganze erläuterte Kunststoffelement ist einstückig.The entire plastic element explained is 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, the springs 18 could lie on the other two sides of the plastic element, where the female coupling members 13 are located, so that a spring 18 is then located between every two female coupling members 13.

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.The assembly of a large number of plastic elements to form the floor covering takes place as follows: A plastic element is placed on a base so that the surfaces 22 shown in FIG. 3 rest on the base (FIGS. 3, 4). The adjacent plastic element is then 13 with its female coupling member brought into the position of Figure 4 and pressed down so that the two resilient pawls 14, 15 are first expanded and then snap into the position of Figure 5 and engage behind the bolt 9. In this way, the male and female coupling elements of adjacent plastic elements are connected to one another. The pawls 14, 15 rest against the end plates 10 by the springs 18, so that there is a distance of a few millimeters between adjacent plastic elements. As a result, when the plastic elements are being laid, they no longer have to be pulled apart in order to produce an expansion joint. If the entire floor covering has been installed, the horizontal loads occurring within the level of the floor covering are absorbed by the horizontal bars 9 with their end plates 10, so that the male coupling elements 9 are only loaded on tension, but no longer on bending, as in the case of known plastic element mentioned above. It can be seen from the figures that the plastic element no longer has any tubular structures as in the known plastic element, so that no dirt can now be deposited in the tubular structures. It can be seen in particular from FIG. 3 that the structure of the underside of the plastic element has only outer surfaces, so that after rain, the moisture can be removed relatively quickly by the air flowing around. This 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.The positive engagement of the pawls 14, 15 on the bolt 9 according to FIG. 5 prevents a plastic element from being set up on one side, so that the floor covering remains completely level. If the floor covering is to be removed, an elastically resilient plastic element according to FIG. 6 is pressed upwards on one side, so that the pawl 15 is disengaged from the latch 9 of the adjacent plastic element is coming.
