Abstract

The invention relates to a surface support specially for floors, walls or the like, comprising substantially rectangular plate-shaped panels (1) with an underside facing the surface (2) which is to be covered, an upper surface (3) facing the room area (3) as well as peripheral face edges (5, 8). The respective face edges of two adjacent panels are provided with tongues (6) while the two other adjacent face edges are provided with grooves (9). When installed, the panels (1) fit closely onto each other due to the tongue/groove joint. In order to improve assembly of said panels so that they can be installed more quickly and economically and to guarantee extremely precise and reliable fit, the panels (1) have locking grooves (20, 22) arranged on their undersides (2) at a distance from their face edges, running parallel to said face edges. At least one fastening clip (17) is inserted into the locking grooves for each second adjacent panel (1). Said fastening clip extends substantially perpendicular to each close-fitting panel (1) face edge and holds the panels tightly together.

Description

Oberflächenaufläge aus tafelförmigen Paneelen Surface coverings made of panel-shaped panels
Die Erfindung betrifft eine Oberflächenauflage, insbesondere für Fußböden, Wände und dergleichen, bestehend aus im wesentlichen rechteckigen, tafelförmigen Paneelen mit je einer dem zu verkleidenden Untergrund zugewandten Unterseite, einer dem Raum zugekehrten Oberseite sowie umlaufenden Stirnkanten, von denen jeweils zwei aneinander angrenzende Stirnkanten eines Paneels mit Federn und die beiden anderen aneinander angrenzenden Stirnkanten mit Nuten versehen sind, wobei die Paneele im verlegten Zustand über die Feder-Nut-Verbindungen dicht aneinander anliegen.The invention relates to a surface covering, in particular for floors, walls and the like, consisting of essentially rectangular, panel-shaped panels, each with an underside facing the surface to be clad, an upper side facing the room and circumferential end edges, each of which has two adjoining end edges of a panel with tongues and the two other adjoining end edges are provided with grooves, the panels lying tightly against one another via the tongue and groove connections in the installed state.
Bekannte Fußböden aus Fertigparkett oder Laminatböden aus beispielsweise HDF-Material (high density Fiberboard) werden in der Regel schwimmend verlegt, wobei die Paneele nur über ihre Feder-Nut-Verbindungen ineinandergesteckt sind. In den Bereichen der Stirnkanten der Paneele können zusätzliche Klebenähte vorgesehen sein. Die Verlegung ist in der Regel problematisch, da häufig keine geometrisch genauen Raummaße vorgegeben sind, so daß es äußerst schwierig ist, die Paneele möglichst ohne Fugenabstand zu verlegen. Unebenheiten im Boden, Spannungen im Material und Fehler bei der Verlegung bewirken unmittelbar nach der Verlegung oder auch zu einem späteren Zeitpunkt die Entstehung von mehr oder weniger breiten Fugen, die es zu vermeiden gilt.Known floors made of prefabricated parquet or laminate floors made of, for example, HDF material (high density fiber board) are generally laid in a floating manner, the panels being inserted into one another only via their tongue and groove connections. Additional adhesive seams can be provided in the areas of the front edges of the panels. The laying is usually problematic, since often no geometrically precise dimensions are given, so that it is extremely difficult to lay the panels without a gap between the joints. Unevenness in the floor, tension in the material and errors in the laying have an immediate effect after laying or at a later point in time, the formation of more or less wide joints that must be avoided.
Der Erfindung liegt die Aufgabe zugrunde, die bekannte Verlegetechnik in der Weise zu verbessern, daß schneller und somit kostengünstiger gearbeitet werden kann und daß darüberhinaus ein äußerst genaues und sicheres Verlegen möglich ist.The invention has for its object to improve the known laying technology in such a way that work can be carried out more quickly and therefore more cost-effectively and that, moreover, extremely precise and safe laying is possible.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Paneele an ihren Unterseiten in einem Abstand von ihren Stimkanten Ausnehmungen aufweisen und daß in die Ausnehmungen je zweier benachbarter Paneele mindestens ein Befestigungsclip eingedrückt ist, der sich im wesentlichen quer zu den jeweili- gen aneinanderliegenden Stirnkanten der Paneele erstreckt und die Paneele fest aneinanderhält .According to the invention, this object is achieved in that the panels have recesses on their undersides at a distance from their end edges and in that at least one fastening clip is pressed into the recesses of two adjacent panels, said fastening clip being essentially transverse to the respective abutting front edges of the panels extends and holds the panels together.
Bei Anwendung der Erfindung kann man also eine erste Reihe der Paneele fest und fugenfrei miteinander verbinden und kann dann diese Reihe nachträglich noch zu den Raumabmessungen ausrichten, so daß beim weiteren Verlegen keine Fehler entstehen, die sich sonst bei herkömmlichen Verlegetechniken von Reihe zu Reihe addieren würden. Wenn die Stirnkanten miteinander verleimt werden sollen, so bilden die Befestigungsclips sofort einen festen Halt, die den Klebevorgang begünstigen. Ein nachträgliches Verschieben der Paneele relativ zueinander wird durch die Befestigungsclipse verhindert, so daß im nachhinein eine absolut glatte Oberflächenauflage mit geschlossenen Fugen entsteht. Man kommt also mit wesentlich geringerem Aufwand als bisher zu einem optimalen Ergebnis, das mit herkömmlichen Mitteln selbst bei sorgfältigster Verlegung nicht erreichbar gewesen ist.When using the invention, you can connect a first row of the panels firmly and jointlessly and then align this row to the room dimensions, so that no errors occur during further laying that would otherwise add up from row to row in conventional laying techniques . If the front edges are to be glued together, the fastening clips immediately form a firm hold, which favors the gluing process. Subsequent displacement of the panels relative to one another is prevented by the fastening clips, so that afterwards an absolutely smooth surface support with closed joints is created. Optimal results can therefore be achieved with much less effort than before, which could not be achieved with conventional means even with the most careful laying.
Die an der Unterseite der Paneele vorgesehenen Ausnehmungen sind vorzugsweise als durchgehende Klemmrillen ausgebildet, die parallel zu den Stirnkanten verlaufen. Aufgrund der durch gehenden Klemmrillen ist es möglich, die Befestigungsclips an beliebigen Stellen und in beliebiger Anzahl anzubringen.The recesses provided on the underside of the panels are preferably designed as continuous clamping grooves which run parallel to the end edges. Because of through outgoing clamping grooves, it is possible to attach the fastening clips at any point and in any number.
Diejenigen Klemmrillen, die den mit den Federn versehenen Stirnkanten der Paneele zugeordnet sind, weisen zweckmäßig den gleichen Abstand von den zugeordneten Stirnkanten auf, während die anderen Klemmrillen, die den mit den Nuten versehenen Stirnkanten zugeordnet sind, ebenfalls jeweils den gleichen Abstand von den zugeordneten Stimkanten aufweisen. Dadurch ist sichergestellt, daß beim Verlegen immer ein gleicher Rillenabstand zwischen zwei benachbarten Paneelen vorliegt, so daß nur ein einziger Typ der Befestigungsclip erforderlich ist.Those clamping grooves which are assigned to the end edges of the panels provided with the springs expediently have the same distance from the assigned end edges, while the other clamping grooves which are assigned to the end edges provided with the grooves likewise each have the same distance from the assigned end edges exhibit. This ensures that there is always the same groove spacing between two adjacent panels when laying, so that only a single type of fastening clip is required.
Der Abstand zwischen den mit den Federn versehenen Stirnkanten und den jeweiligen zugeordneten Klemmrillen kann größer sein als der Abstand zwischen den mit den Nuten versehenen Stirnkanten und den jeweiligen zugeordneten Klemmrillen.The distance between the end edges provided with the springs and the respective assigned clamping grooves can be greater than the distance between the end edges provided with the grooves and the respective assigned clamping grooves.
Die Klemmrillen sind vorzugsweise als Ausfräsungen ausgebildet, die einen im wesentlichen rechteckigen Querschnitt aufweisen. Derartige Klemmrillen lassen sich leicht herstellen und die Befestigungsclips können bequem eingedrückt werden. Die oberen Begrenzungskanten der Klemmrillen können leicht gebrochen bzw. mit einer Fase versehen sein, so daß sich das Montagepersonal nicht an eventuellen scharfen Kanten verletzt. Darüberhinaus erleichtern die abgeschrägten Kanten der Klemmrillen das Aufstecken der Befestigungsclips.The clamping grooves are preferably formed as cutouts which have an essentially rectangular cross section. Such clamping grooves are easy to manufacture and the fastening clips can be easily pressed in. The upper boundary edges of the clamping grooves can be slightly broken or beveled so that the assembly personnel are not injured by any sharp edges. In addition, the bevelled edges of the clamping grooves make it easier to attach the fastening clips.
Die Befestigungsclips sind vorzugsweise als Federstahlbänder ausgebildet, wobei die Federstahlbänder an ihren Enden hakenförmige Abkröpfungen aufweisen, die in die Klemmrillen zweier benachbarter Paneele eingedrückt werden. Die hakenförmigen Ab- kröpfungen der Befestigungsclips können dabei aufeinanderzuge- neigt sein und liegen dann an der der Feder-Nut-Verbindung zugewandten Innenwand der jeweiligen Klemmrille an. Aufgrund der nach innen geneigten Abkröpfungen können diese die Paneele unter hoher Zugspannung gegeneinanderziehen.The fastening clips are preferably designed as spring steel strips, the spring steel strips having hook-shaped offsets at their ends, which are pressed into the clamping grooves of two adjacent panels. The hook-shaped bent portions of the fastening clips can be inclined towards one another and then lie against the inner wall of the respective clamping groove facing the tongue and groove connection. Due to the bends bent inwards can pull the panels against each other under high tensile stress.
Die aufeinanderzu geneigten hakenförmigen Abkröpfungen können an ihren freien Enden eine Abrundung aufweisen, so daß ein leichtes Eindrücken und Spannen der Befestigungsclips möglich ist. Die Abrundungen können dabei als entgegengesetzt umgebogene Schenkel ausgebildet sein, so daß die Herstellung der Clips relativ einfach ist.The hook-shaped cranks which are inclined towards one another can have a rounded portion at their free ends, so that the fastening clips can be easily pressed in and tensioned. The roundings can be designed as oppositely bent legs, so that the production of the clips is relatively simple.

Im Bereich der Stirnkanten der Paneele kann das Paneelenmate- rial unterhalb der Feder-Nut-Verbindung einen Rücksprung aufweisen, der weiter zurückliegt als das Paneelenmaterial oberhalb der Feder-Nut-Verbindung. Im verlegten Zustand verbleibt somit an der Unterseite ein Schlitz, während das Material an der Oberseite dicht aneinander anliegt und eine glatte Fläche bildet. Durch die Vorspannung der Befestigungsclips kann somit das Material oberhalb der Nut-Feder-Verbindung fest zusammengedrückt werden, ohne daß es bei eventuellen Produktionsunge- nauigkeiten zuerst zu einer Anlage im unteren Bereich kommen kann. Der Rücksprung des Paneelenmaterials ist zweckmäßig an den mit den Federn versehenen Stirnkanten ausgebildet.In the area of the front edges of the panels, the panel material below the tongue and groove connection can have a recess that lies further back than the panel material above the tongue and groove connection. When installed, a slot remains on the underside, while the material on the top lies close together and forms a smooth surface. The pre-tensioning of the fastening clips enables the material above the tongue and groove connection to be firmly pressed together without first causing a system in the lower area in the event of any production inaccuracies. The recess of the panel material is expediently formed on the end edges provided with the springs.
Ferner sollte die Feder nur so lang ausgebildet sein, daß sie im verlegten Zustand der Paneele nicht am Grund der Nut anliegt, so daß gewährleistet ist, daß das Paneelenmaterial in jedem Falle im Bereich seiner Oberseite dicht und genau definiert aneinander anliegt. Diese Wirkung kann gezielt auch da- durch unterstützt werden, daß im Bereich der Stirnkanten der Paneele oberhalb der Feder das Paneelenmaterial eine Abschrägung aufweist, die im Bereich der Oberseite der Paneele am weitesten vorsteht und im verlegten Zustand den einzigen Anlagebereich bildet. Durch diese Maßnahme wird eine relativ kleine Berührungsfläche geschaffen, die ein gutes und zuverlässiges Aneinanderdrücken gewährleistet. Darüberhinaus gewährleistet diese Geometrie, sofern die Stirnkanten mit einander verleimt werden sollen, einen guten Leimfluß.Furthermore, the tongue should only be so long that it does not abut the bottom of the groove in the installed state of the panels, so that it is ensured that the panel material lies tightly and precisely defined against each other in the area of its top side. This effect can also be targeted are supported by the fact that in the area of the front edges of the panels above the spring the panel material has a bevel which protrudes furthest in the area of the top of the panels and forms the only contact area in the installed state. This measure creates a relatively small contact area, which ensures a good and reliable pressing together. In addition, this geometry ensures a good flow of glue if the end edges are to be glued together.
Die Erfindgung ist in der Zeichnung beispielsweise veranschaulicht und im Nachstehenden im einzelnen an Hand der Zeichnung beschrieben.The invention is illustrated in the drawing, for example, and described in detail below with reference to the drawing.

Nach der Zeichnung wird die Oberflächenauflage, die im vorliegenden Fall für Fußböden vorgesehen ist, aus einzelnen Paneelen 1 zusammengesetzt. Die Paneele 1 sind rechteckig ausge- bildet und bestehen aus flachem, tafelförmigem Material, beispielsweise HDF-Material (high density Fiberboard), welches für den Fußbodenbereich vorzugsweise eine Stärke von ca. 8 mm auf weist.According to the drawing, the surface support, which is provided for floors in the present case, is composed of individual panels 1. The panels 1 are rectangular forms and consists of flat, tabular material, for example HDF material (high density fiber board), which preferably has a thickness of approximately 8 mm for the floor area.
Die auf den Boden aufzulegende Unterseite 2 des Paneels 1 ist mit Balancepapier oder dergleichen versehen, während die zum Raum gewandte Oberseite 3 mit Dekorpapier, beispielsweise mit einem Holzdekor, beschichtet ist.The bottom 2 of the panel 1 to be placed on the floor is provided with balance paper or the like, while the top 3 facing the room is coated with decorative paper, for example with a wood decor.
Jeweils zwei aneinander angrenzende Stirnkanten 4, 5 eines Paneels 1 sind mit einer einstückig angeformten Feder 6 versehen, während die beiden anderen aneinander angrenzenden Stirnkanten 7, 8 mit einer eingearbeiteten Nut 9 versehen sind.In each case two adjoining end edges 4, 5 of a panel 1 are provided with an integrally molded spring 6, while the other two adjoining end edges 7, 8 are provided with an incorporated groove 9.
Nach Fig. 3 der Zeichnung, in der die mit der Feder 6 versehene Stirnkante 5 des Paneels 1 in vergrößertem Maßstab dargestellt ist, weist das Paneelenmaterial unterhalb der Feder 6 einen Rücksprung 10 auf, der weiter zurückliegt als das Panee- lenmaterial oberhalb der Feder 6. Oberhalb der Feder 6 ist das Paneelenmaterial mit einer Abschrägung 11 versehen, die im BeBereich der Oberseite des Paneels am weitesten zum freien Ende hin vorsteht.3 of the drawing, in which the front edge 5 of the panel 1 provided with the spring 6 is shown on an enlarged scale, the panel material below the spring 6 has a recess 10 which lies further back than the panel material above the spring 6 Above the spring 6, the panel material is provided with a bevel 11 which protrudes furthest towards the free end in the area of the top of the panel.
Nach Fig. 4, in welcher die mit der Nut 9 versehene Stirnkante 8 des Paneels 1 in vergrößertem Maßstab dargestellt ist, ist die Nut 9 mit relativ großen Abrundungsradien im Bereich der Kanten versehen, so daß beim Verlegen ein leichtes Einsetzen der Feder 6 des benachbarten Paneels 1 möglich ist.4, in which the end edge 8 of the panel 1, which is provided with the groove 9, is shown on an enlarged scale, the groove 9 is provided with relatively large radii of curvature in the region of the edges, so that the tongue 6 of the adjacent one can be easily inserted when laying Panel 1 is possible.
In dem Bereich oberhalb der Nut 9 ist das Paneelenmaterial mit einer Abschrägung 12 versehen. Nahe der Oberfläche geht die Abschrägung in einen flachen Bereich 13 über, der im verlegten Zustand mit einem entsprechenden flachen Bereich 14 oberhalb der Feder 6 des benachbarten Paneels zusammenwirkt, wobei die beiden flachen Bereiche 13 und 14 dicht aneinander anliegen. Der wirksame Bereich 15 der Nuttiefe ist dabei etwas länger als der wirksame Bereich 16 der Federlänge, so daß, wie aus Fig. 5 hervorgeht, im verlegten Zustand die Feder 6 die Nut 9 nicht ganz ausfüllen. Darüberhinaus bleibt auch der Rücksprung 10 unter der Feder-Nut-Verbindung frei, so daß zwei benachbarte Panelee 1 nur in ihren oberen flachen Bereichen 13 und 14 aneinander anliegen.In the area above the groove 9, the panel material is provided with a bevel 12. Near the surface, the bevel merges into a flat area 13, which in the installed state interacts with a corresponding flat area 14 above the spring 6 of the adjacent panel, the two flat areas 13 and 14 abutting one another closely. The effective area 15 of the groove depth is somewhat longer than the effective area 16 of the tongue length, so that, as can be seen from FIG. 5, the tongue 6 in the installed state does not completely fill the groove 9. In addition, the recess 10 remains free under the tongue and groove connection, so that two adjacent panels 1 only abut one another in their upper flat areas 13 and 14.
Zur festen Verbindung der verlegten Paneele 1 dienen Befesti- gungsclips 17, die aus dünnen Federstahlbändern hergestellt werden und an den Unterseiten 2 der verlegten Paneele 1 angebracht werden. An der Oberfläche der verlegten Auflage sind die Befestigungsclips 17 folglich nicht sichtbar.Fastening clips 17, which are made from thin spring steel strips and are attached to the undersides 2 of the installed panels 1, serve for the firm connection of the installed panels 1. The fastening clips 17 are consequently not visible on the surface of the laid support.
Die Befestigungsclips 17 werden in Ausnehmungen 18 eingedrückt, die an den Unterseiten 2 der Paneele 1 ausgebildet sind. Wie aus Fig. 2 zu ersehen ist, sind die Ausnehmungen 18 als durchgehende Klemmrillen 19, 20, 21 und 22 ausgebildet, die parallel zu den Stirnkanten 4, 5, 7, 8 verlaufen. Die Klemmrillen sind als Ausfräsungen ausgebildet, die einen rechteckigen Querschnitt aufweisen.The fastening clips 17 are pressed into recesses 18 which are formed on the undersides 2 of the panels 1. As can be seen from FIG. 2, the recesses 18 are designed as continuous clamping grooves 19, 20, 21 and 22 which run parallel to the front edges 4, 5, 7, 8. The clamping grooves are designed as cutouts that have a rectangular cross section.
Die Klemmrillen 19 und 20, die parallel zu den mit den Federn 6 versehenen Stirnkanten 4 und 5 verlaufen, haben einen etwas größeren Abstand von den Stirnkanten, und zwar im vorliegenden Ausführungsbeispiel von ca. 45 mm. Die Klemmrillen 21 und 22, die parallel zu den mit der Nut 9 versehenen Stirnkanten 7 und 8 verlaufen, haben einen etwas geringeren Abstand von den Stirnkanten, und zwar im vorliegenden Ausführungsbeispiel von ca. 30 mm.The clamping grooves 19 and 20, which run parallel to the end edges 4 and 5 provided with the springs 6, have a somewhat larger distance from the end edges, in the present exemplary embodiment of approximately 45 mm. The clamping grooves 21 and 22, which run parallel to the end edges 7 and 8 provided with the groove 9, have a somewhat smaller distance from the end edges, in the present exemplary embodiment of approximately 30 mm.
Die im vorliegenden Ausführungsbeispiel verwendeten Befestigungsclips 17, die eine Breite von ca. 20 mm aufweisen, müssen, wie in Fig. 6 dargestellt, den Bereich zwischen zwei Klemmrillen überbrücken. Zur Befestigung in den Klemmrillen weisen die Befestigungsclips 17 an ihren beiden freien Enden hakenförmige Abkröpfungen 23 auf, die aufeinanderzu geneigt sind und an der der Feder-Nut-Verbindung zugewandten Innenwand der jeweiligen Klemmrille unter Spannung anliegen. Die Abkröpfungen 23 weisen an ihren freien Enden Abrundungen 24 auf, an die sich entgegengesetzt umgebogene Schenkel 25 anschließen.The fastening clips 17 used in the present exemplary embodiment, which have a width of approximately 20 mm, must, as shown in FIG. 6, bridge the area between two clamping grooves. For fastening in the clamping grooves, the fastening clips 17 have two free ends hook-shaped offsets 23 which are inclined towards one another and bear under tension on the inner wall of the respective clamping groove facing the tongue-and-groove connection. The bends 23 have rounded ends 24 at their free ends, to which legs 25 bent in opposite directions are connected.
Wie aus Fig. 5 zu ersehen ist, liegen die entgegengesetzt umgebogenen Schenkel 25 im montierten Zustand nach Art eines Wi- derhakens an der der Feder-Nut-Verbindung abgewandten Innenwand der jeweiligen Klemmrille an.As can be seen from FIG. 5, the oppositely bent legs 25 rest in the assembled state in the manner of a barb on the inner wall of the respective clamping groove facing away from the tongue and groove connection.
Beim Verlegen der Paneele 1 wird zunächst an einer Raumwand eine Paneelenreihe oder eine versetzte Doppelreihe fest mit Hilfe der Befestigungsclips 17 verbunden, so daß die gesamte Reihe bzw. Doppelreihe bequem zu der jeweiligen Wand ausgerichtet werden kann. Ein Verrutschen der Paneele 1 relativ zueinander ist durch die Befestigungsclips 17 ausgeschlossen. Zusätzlich können die Stirnkanten der Paneele 1 auch noch verleimt werden, bevor die Befestigungsclips 17 aufgesetzt werden.When laying the panels 1, a row of panels or an offset double row is first firmly connected to the wall of the room with the aid of the fastening clips 17, so that the entire row or double row can be easily aligned with the respective wall. Slipping of the panels 1 relative to one another is prevented by the fastening clips 17. In addition, the end edges of the panels 1 can also be glued before the fastening clips 17 are attached.
An die ordnungsgemäß verlegte erste Reihe bzw. Doppereihe können sich dann die weiteren Reihen der Paneele 1 anschließen, wobei die Befestigungsclips in beiden Hauptrichtungen als Fixierung dienen. The further rows of panels 1 can then be connected to the properly laid first row or double row, the fastening clips serving as fixation in both main directions.
