Description

Die Erfindung betrifft ein Verbindungssystem für einen mobilen Boden mit einer Vielzahl von in Draufsicht rechteckförmigen Platten, die jeweils an ihren Längskanten mit benachbarten Platten verbindbar sind, wobei die Platten eine gemeinsame Oberfläche ausbilden und zur Verbindung zweier längsseitig benachbarter Platten jeweils ein Nutstück und ein Federstück in den Längskanten der benachbarten Platten angeordnet sind und das Nutstück und das Federstück aus einem formstabilen Material bestehen.The invention relates to a connection system for a mobile floor with a plurality of rectangular in plan view plates, which are connectable at their longitudinal edges with adjacent plates, wherein the plates form a common surface and for connecting two longitudinally adjacent plates in each case a Nutstück and a spring piece in the longitudinal edges of the adjacent plates are arranged and the groove piece and the spring piece made of a dimensionally stable material.

Die WO 01/98604 zeigt einen Bodenbelag mit einzelnen Platten, die an ihren Längsseiten über ein Verriegelungssystem miteinander lösbar verbunden werden.The WO 01/98604 shows a floor covering with individual plates, which are detachably connected together on their longitudinal sides via a locking system.

Aus der DE 203 07 074.7 ist bereits ein Verbindungssystem für Böden bekannt, bei dem zwei benachbarte Platten entlang ihrer Längskanten ineinander schwenkbar sind, so dass diese in einer horizontalen benachbarten Position im wesentlichen formschlüssig aneinander gehalten sind. Es existieren eine Reihe solcher Verbindungssysteme und diese können sowohl integral aus dem Material der Platte gefräst oder durch metallische Elemente gebildet sein. Nachteilig an den vorgenannten Systemen ist, dass diese nur unter erheblichem Zeit- und damit auch Kostenaufwand zusammensetzbar und zerlegbar sind.From the DE 203 07 074.7 a connection system for floors is already known, in which two adjacent plates are pivotable into one another along their longitudinal edges, so that they are held in a substantially horizontal position adjacent each other in a form-fitting manner. There are a number of such connection systems and these can both be machined from the material of the plate or formed by metallic elements. A disadvantage of the aforementioned systems is that they can be assembled and disassembled only with considerable time and thus also cost.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verbindungssystem für mobile Böden zu schaffen, das schnell zu verlegen ist.Object of the present invention is therefore to provide a connection system for mobile floors, which is easy to install.

Diese Aufgabe wird mit einem Verbindungssystem für mobile Böden mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with a connection system for mobile floors with the features of claim 1.

Erfindungsgemäß weist das Nutstück einen von dem Plattenmaterial umgebenen Steg, eine sich an diesen anschließende Nut, deren Öffnung sich von ihrer geschlossenen Seite zur offenen Seite hin verengt, und eine sich an den unteren Rand der Nut anschließende Zunge und das Federstück einen von dem Plattenmaterial umgebenen Steg, eine von dem Steg weg schräg nach oben verlaufende Feder auf, und weist eine Schiene auf, die aus dem hinteren Bereich der Feder nach oben hervorsteht. Dadurch ist ein einfaches Zerlegen bzw. Zusammensetzen der Bodenplatten entlang ihrer Längsseiten gesichert und die Platten sind stabil aneinander gehalten.According to the invention, the groove piece has a web surrounded by the plate material, a groove adjoining the latter, the opening of which narrows from its closed side to the open side, and a tongue adjoining the lower edge of the groove and the spring piece surrounded by the plate material Web, an obliquely upward away from the web spring on, and has a rail which protrudes from the rear region of the spring upwards. As a result, a simple disassembly or assembly of the floor panels is secured along their longitudinal sides and the plates are stably held together.

Gemäß der Erfindung weist die Zunge des Nutstücks eine Mulde und die Feder an ihrer Unterseite eine Ausbauchung auf, welche formschlüssig ineinander greifen, so dass ein Gelenk ausgebildet ist. Dadurch wird eine besonderes simple und, im Zusammenwirken mit der schräg nach oben verlaufenden Feder, sichere Arretierung des Nutstücks mit dem Federstück bewirkt.According to the invention, the tongue of the Nutstücks a trough and the spring on its underside a bulge, which engage in a form-fitting manner, so that a joint is formed. As a result, a special simple and, in cooperation with the obliquely upwardly extending spring, secure locking of the Nutstücks causes the spring piece.

Zur Befestigung des Nutstücks und der Federstücks in der Bodenplatte vorgesehenen Spalten sind vorzugsweise der Steg des Nutstücks und/oder der Steg des Federstücks in den Längskanten der Platten eingeklebt. Um eine besonders gute Verteilung des Klebers entlang der Nut- und/oder Federstege zu erreichen, befinden sich bevorzugt eine oder mehrere Rillen im Steg des Nutstücks und/oder im Steg des Federstücks, die vorzugsweise parallel zur Längskante der Bodenplatte verlaufen.For fixing the Nutstücks and the spring piece provided in the bottom plate columns preferably the web of the Nutstücks and / or the web of the spring piece are glued in the longitudinal edges of the plates. In order to achieve a particularly good distribution of the adhesive along the groove and / or spring bars, are preferably one or more grooves in the web of Nutstücks and / or in the web of the spring piece, which are preferably parallel to the longitudinal edge of the bottom plate.

Für die Gewährleistung einer besonderen Festigkeit und Haltbarkeit besteht das Nutstück und/oder das Federstück aus Metall. Um dauerhaft aneinander grenzender Platten spaltenfrei miteinander zu verbinden, bilden eine Stirnkante eines oberen Nutschenkels zusammen mit einer Stirnkante der Schiene des Federstücks einen Anschlag aus.To ensure a special strength and durability consists of the groove piece and / or the spring piece made of metal. To connect permanently adjacent plates gap-free with each other, form an end edge of an upper groove leg together with an end edge of the rail of the spring piece a stop.

Aufgrund der geometrischen Gestalt des Nutstücks und des Federstücks sind diese bereits in einem Winkel von 5° bis 25°, in einer noch bevorzugteren Ausführungsform in einem Winkel von 10° bis 20° voneinander trennbar, wodurch insbesondere ein schnelles Verlegen und eine schnelle Demontage des mobilen Bodens ermöglicht.Due to the geometric shape of the Nutstücks and the spring piece they are already separated at an angle of 5 ° to 25 °, in an even more preferred embodiment at an angle of 10 ° to 20 ° apart, which in particular a quick installation and rapid disassembly of the mobile Soil allows.

Vorteilhaft ist außerdem, dass die Längskanten der Platten bei einem stirnseitigen Ausklinken der Platten durch eine Unterfütterung des Plattenoberflächenmaterials mit dem Nutstück bzw. dem Federstück gestützt sind. Dadurch wird ein Abbrechen einer Deckschicht insbesondere der besonders belasteten Plattenecken verhindert.It is also advantageous that the longitudinal edges of the plates are supported in a face-side notching of the plates by a relining of the plate surface material with the groove piece or the spring piece. This prevents the breaking off of a cover layer, in particular of the particularly stressed panel corners.

Des weiteren wird die Flexibilität des Boden bei einer großflächigen Verkrümmung aufgrund einer Belastung dadurch erhöht, dass im zusammengesetzten Zustand von Nutstück und Federstück eine Oberseite der Feder an dem oberen Nutschenkel anliegt und zwischen einem unteren Nutschenkel und der Feder ein Hohlraum ausgebildet ist, der sich zur Mulde hin schließt. Dadurch ist ein Toleranzausgleich möglich, da sich die Feder etwas nach unten durchbiegen kann.Furthermore, the flexibility of the soil is increased in a large-scale curvature due to a load that in the assembled state of Nutstück and spring piece, an upper side of the spring rests against the upper groove leg and between a lower groove leg and the spring, a cavity is formed, which is to Mulde closes. This tolerance compensation is possible because the spring can bend slightly downwards.

Gemäß einer weiteren Ausführungsform sind die Stirnseiten benachbarter Platten durch einen an der ersten Platte festgelegten und von dieser hervorstehenden Steg, aus dessen hervorstehendem Stück ein Dorn nach oben hervorsteht, der in eine Aufnahme der benachbarten Platte eingreift, miteinander verbindbar, um eine formschlüssige stirnseitige Verbindung zwischen den Platten herzustellen.According to a further embodiment, the end faces of adjacent plates are connected to each other by a first plate fixed to and protruding from the web, from the protruding piece of a pin protrudes upwards, which engages in a receptacle of the adjacent plate to form a positive end-side connection between to make the plates.

Ein Boden ist durch eine Vielzahl von benachbart angeordneten Platten 1 gebildet, die jeweils an gegenüberliegenden Längskanten sowie gegenüberliegenden Stirnkanten verbunden sind. Die randseitig angeordneten Platten können nach außen hin entweder von einem Rahmen umgeben sein oder einen entsprechenden Abschluß aufweisen, da dort keine Verbindung zu einer benachbarten Platte hergestellt werden muß.A bottom is formed by a plurality of adjacently arranged plates 1, each at opposite longitudinal edges and opposite end edges are connected. The plates arranged at the edge can either be surrounded by a frame towards the outside or have a corresponding termination, since there no connection to an adjacent plate has to be made.

Eine Ausführungsform für das Verbindungssystem an den Längskanten ist in den Figuren 2 bis 4 im Schnitt dargestellt. An einer der Längskanten ist ein aus Metall, insbesondere Aluminium, bestehendes Nutstück 2 angeordnet, das mit einem Steg 21 in die Platte 1 eingreift und dort verklebt ist. In dieses Nutstück greift ein in der gegenüberliegenden Platte 1 aus Metall, insbesondere Aluminium, bestehendes Federstück 3 ein, wobei das Federstück 3 mit einem Steg 31 in die Platte 1 eingreift und dort verklebt ist. Im montierten Zustand liegen die Platten 1 in einer horizontalen Ebene nebeneinander und bilden eine Oberfläche aus. Das Verbindungssystem ist von außen nicht sichtbar und das Federstück 3 greift in das Nutstück 2 ein. Das Nutstück 2 weist neben dem Steg 21 eine sich an diesen anschließende Nut 22 auf, deren Öffnung sich von ihrer geschlossenen Seite zur offenen Seite hin verengt. An den unteren Rand der Nut schließt sich eine Zunge 23 an, die eine gerundete Mulde 24 aufweist. Das Federstück weist neben dem oben erwähnten Steg 31 eine von dem Steg 31 weg schräg nach oben verlaufende Feder 32 auf, die die sich von ihrer geschlossenen Seite zur offenen Seite hin verengende Nut 22 hintergreift. An der hinteren unteren Seite der Feder 32 ist eine Ausbauchung 34 ausgeformt, die mit der Mulde 24 des Nutstücks 2 formschlüssig ineinander greift. Im zusammengesetzten Zustand von Nutstück 2 und Federstück 3 liegt eine Oberseite der Feder 32 der unteren Seite eines oberen Nutschenkel 26 an und zwischen einem unteren Nutschenkel 27 und der Feder 32 ist ein Hohlraum 28 ausgebildet, der sich zur Mulde 24 hin schließt. Der Nutschenkel 26 verbreitert sich dabei zur Endseite hin, so dass die Nut sich keilförmig erweitert. Dadurch ist ein Toleranzraum für Belastungen der Platten 1 gegeben, bei der die Platten 1 nach unten durchgedrückt werden können.An embodiment of the connection system at the longitudinal edges is in the FIGS. 2 to 4 shown in section. On one of the longitudinal edges of a metal, in particular aluminum, existing groove piece 2 is arranged, which engages with a web 21 in the plate 1 and is glued there. In this groove piece engages in the opposite plate 1 made of metal, in particular aluminum, existing spring piece 3, wherein the spring piece 3 engages with a web 31 in the plate 1 and is glued there. In the mounted state, the plates 1 lie next to one another in a horizontal plane and form a surface. The connection system is not visible from the outside and the spring piece 3 engages in the groove piece 2 a. The groove piece 2 has, in addition to the web 21, a groove 22 adjoining it, the opening of which narrows from its closed side to the open side. At the bottom of the groove, a tongue 23 connects, which has a rounded trough 24. The spring piece has, in addition to the above-mentioned web 31, a spring 32 running obliquely upward away from the web 31, which engages behind the groove 22 narrowing from its closed side toward the open side. At the rear lower side of the spring 32, a bulge 34 is formed, which engages with the trough 24 of the Nutstücks 2 form-fitting manner. In the assembled state of Nutstück 2 and spring piece 3 is an upper side of the spring 32 of the lower side of an upper groove leg 26 and between a lower groove leg 27 and the spring 32, a cavity 28 is formed, which closes to the trough 24 out. The groove leg 26 widened towards the end side, so that the groove widens wedge-shaped. As a result, a tolerance space for loads of the plates 1 is given, in which the plates 1 can be pushed down.

Aufgrund der Geometrie von Nut- 2 und Federstück 3 sind das Nut- 2 und Federstück 3 in einem für den Auf- und Abbau sehr günstigen Winkelbereich von 5° bis 25° voneinander trennbar und bieten dennoch in fertig montiertem Zustand einen sicheren Zusammenhalt gegen Auseinanderziehen in horizontale Richtung. In einer besonderen Ausführungsform sind diese sogar in einem Winkelbereich von 10° bis 20° voneinander trennbar. Außerdem werden die Längskanten der Platten 1 bei einem stirnseitigen Ausklinken der Platten durch eine Unterfütterung des Plattenoberflächenmaterials mit dem Nutstück 2 bzw. dem Federstück 3 gestützt. Dadurch sind insbesondere die Eckbereiche der Platten vor Bruch geschützt. Aus dem hinteren Bereich der Feder steht eine Schiene 33 nach oben hervor, die zusammen mit einer Stirnkante eines oberen Nutschenkels einen stabilen Anschlag ausbilden. Die Stege von Nut- und Federstück sind mit Rillen 25, 35 versehen, um eine gleichmäßige Verteilung eines Klebstoffes entlang der Stege zu gewährleisten.Due to the geometry of groove 2 and spring piece 3, the groove 2 and spring piece 3 are separable from each other in a very favorable for the construction and dismantling angle range of 5 ° to 25 ° and yet provide in the assembled state a secure cohesion against pulling in horizontal direction. In a special embodiment, these are even in an angular range of 10 ° to 20 ° separable from each other. In addition, the longitudinal edges of the plates 1 are supported in a face-side notching of the plates by a relining of the plate surface material with the groove piece 2 and the spring piece 3. As a result, in particular the corner regions of the plates are protected against breakage. From the rear region of the spring, a rail 33 protrudes upward, which forms a stable stop together with an end edge of an upper groove leg. The webs of tongue and groove are provided with grooves 25, 35 to ensure a uniform distribution of an adhesive along the webs.

In Figur 5 ist die Verbindung zweier Stirnkanten von benachbarten Platten 1 dargestellt. An einer Platte 1 ist ein aus Metall bestehender Steg 4 festgelegt, der über die Stirnkante der Platte 1 hervorsteht. An dem hervorstehenden Teil des Stegs 4 ist ein nach oben gerichteter Dorn 5 mit einem kegelstumpfförmigen Abschnitt 51 in dessen oberen Bereich ausgebildet. Der Dorn 5 ist in einer Aufnahme 6 angeordnet, die aus einem haubenförmigen Kunststoffteil gebildet ist, welches mittels Zähnen in das Material der Platte eingefasst ist. Um eine Beschädigung des Holzmaterials durch den Dorn zu verhindern, ist die Aufnahme von eine Deckschicht 61 bedeckt. Die Ausbildung eines Spalts zwischen den Stirnkanten benachbarter Platten wird durch das formschlüssige Festhalten des Doms 5 in der Aufnahme 6 verhindert. Beim Auftreten einer Zugbelastung drückt der Dorn 5 gegen die Aufnahme 6, wodurch ein Auseinandergleiten der Platten 1 verhindert wird. Die Aufnahme 6 bewirkt, dass die aus Holzwerkstoff bestehende Platte 1 nicht einreißt. Eine Feder 7, die zu gleichen Anteilen in eine Nut an den Stirnkanten der benachbarten Platten 1 eingeschoben ist und sich im wesentlichen über die gesamte Länge der Stirnkanten erstreckt, verhindert ein Verdrehen der Platten 1 im Bereich der Stirnkanten. Die leistenförmige Feder 7 ist zum Ende hin sich verjüngend keilförmige ausgebildet, so dass sie klemmend in der Nut festlegbar ist, die zumindest teilweise ebenfalls keilförmig ausgebildet sein kann. Der Steg 4 ist an der gegenüberliegenden Platte mit einem Zentrierzapfen 8 positioniert und über schematisch dargestellte Schraubverbindungen 9 mit der Platte 1 verschraubt. Der Zentrierzapfen 8 ist in einer Bohrung in der Platte 1 gehalten.In FIG. 5 the connection of two end edges of adjacent plates 1 is shown. On a plate 1, an existing metal web 4 is fixed, which protrudes beyond the front edge of the plate 1. On the protruding part of the land 4, an upward-facing mandrel 5 having a frusto-conical portion 51 is formed in the upper portion thereof. The mandrel 5 is arranged in a receptacle 6, which is formed from a hood-shaped plastic part, which is enclosed by means of teeth in the material of the plate. To prevent damage to the wood material by the mandrel, the receptacle is covered by a cover layer 61. The formation of a gap between the end edges of adjacent plates is prevented by the positive retention of the dome 5 in the receptacle 6. Upon the occurrence of a tensile load of the mandrel 5 presses against the receptacle 6, whereby a sliding apart of the plates 1 is prevented. The receptacle 6 causes the existing of wood material plate 1 does not tear. A spring 7, which is inserted in equal shares in a groove on the end edges of the adjacent plates 1 and extends substantially over the entire length of the end edges, prevents rotation of the plates 1 in the region of the end edges. The strip-shaped spring 7 is tapered wedge-shaped towards the end, so that it is clamped in the groove can be fixed, which may be at least partially also wedge-shaped. The web 4 is positioned on the opposite plate with a centering pin 8 and screwed via schematically illustrated screw 9 with the plate 1. The centering pin 8 is held in a bore in the plate 1.

In Figur 6 ist eine leicht modifizierte Ausführungsform eines Verbindungssystems mit einem leistenförmigen Nutstück 2' und Federstück 3' gezeigt. Das Nutstück 2' umfasst einen unteren längeren Schenkel 27 und einen oberen kürzeren Schenkel 26, der endseitig auf der Unterseite eine Fase 29 aufweist. Dadurch ist zwischen einer schräg nach oben hervorstehenden Feder 32, der nach oben gerichteten Schiene 33 und dem oberen Schenkel 26 ein Hohlraum 30 ausgebildet, der das Montieren und Demontieren des Verbindungssystems vereinfacht. Denn die in einem Winkel zwischen 5° und 15°, vorzugsweise etwa 10° gegenüber der Horizontalen schräg nach oben gerichtete Feder 32 kann durch den Hohlraum 30 und den Hohlraum 28 zwischen der Feder 32 und dem unteren Schenkel 27 kann die Feder 32 im verlegten Zustand zwar an der schrägen Unterseite des Schenkels 26 anliegen und für eine Verriegelung sorgen, aber zum Demontieren auf einfache Weise verschwenkt und aus dem Nutstück 2' entfernt werden.In FIG. 6 is a slightly modified embodiment of a connection system with a strip-shaped groove piece 2 'and spring piece 3' shown. The groove piece 2 'comprises a lower, longer leg 27 and an upper, shorter leg 26, which has a chamfer 29 at the bottom end. As a result, between an obliquely upwardly projecting spring 32, the upwardly directed rail 33 and the upper leg 26, a cavity 30 is formed, which simplifies the mounting and dismounting of the connection system. Because at an angle between 5 ° and 15 °, preferably about 10 ° relative to the horizontal obliquely upward spring 32 can through the cavity 30 and the cavity 28 between the spring 32 and the lower leg 27, the spring 32 in the installed state Although abut on the oblique bottom of the leg 26 and provide a lock, but pivoted to disassemble in a simple manner and be removed from the groove piece 2 '.

Die Platten 1 sind an ihrer Unterseite mit einer Schicht aus Schaumstoff 10 verklebt, die bodenseitig mit einem Vliesstoffmaterial abgedeckt sein kann.
