Definitions
- the invention relates to floorboards.
- floorboards is subsequently any Floor covering construed in which at least two identically constructed elements be engaged with each other.
- Examples of claimed in the invention floorboards are under other prefabricated parquet with a wear layer, the manner of a Schiffsêtparquet or designed in the manner of a plank.
- the floorboards also count Three-layer planks, consisting of three layers of approximately equal thickness, preferably solid wood or veneer are constructed.
- Floor boards, in the context of the invention are often composed of three layers. Examples for this are Prefabricated parquet with a thin layer of veneer or solid wood, a central layer made of glued or glued sticks and a counterpoise of inferior Veneer or solid wood. The layers are about 90 ° with the main fiber direction offset to each other to achieve maximum dimensional stability. Layered boards are usually of three approximately equally strong and qualitatively approximately equal layers of Solid wood or veneer built. Veneer or bar racks are on individual products also by wood material layers or plates to replace.
- WO 00/47841 proposes floor panels on all sides with a Provide profile, in which a perpendicular to the plate plane to be closed connection is proposed, which provides groove, spring and locking elements.
- the locking elements should have a horizontal contact surface and a shifting of the Prevent floor panels perpendicular to the board plane.
- the locking elements should be elastic.
- the disadvantage of this solution is that either separate Components must be inserted or glued, the parts of the locking elements and which are positioned very precisely for exact locking have to. This is laborious.
- Another disadvantage is that the locking elements when joining can be easily damaged when on the in WO 00/47841 proposed manner have horizontal contact surfaces.
- the elastic deformability of spring or tongue and groove so the deflection of Spring or tongue and groove when joining the profile or second floor elements also contribute to the protection of the locking elements and of the groove and spring at.
- the deflection of the spring or tongue and groove protects the corresponding Locking elements when joining the floorboards be engaged with each other.
- the floor elements or floorboards to be joined are in their horizontal Position set particularly effective to each other when tongue and groove formed as a cone are. This positive connection of the profile fixes the two floorboards in a simple and secure way.
- the conicity of tongue and groove can be maintained be, even if corresponding locking elements or special Embodiments of tongue and groove are provided. It is enough if tongue and groove at least partially designed for conical engagement.
- the spring of the profile is designed so that that it is deflected when joining the profile, and then after that Engagement of tongue and groove again assume the starting position.
- This elasticity can be made by giving the required clearance for the engagement of a lip the groove is required, so deeply worked out that the remaining connecting bar allows the profile or the floor element deflecting the spring.
- the spring of the profile is in two parts educated.
- a first spring part is elastic, a second spring part is rigidly formed.
- On the elastic first spring part is a first part of a corresponding Locking means arranged.
- the elastic first spring member may be formed so that a deformation and deflecting while assembling the profile. It is preferred but if between the first and second spring part a free space is created, the a deflection of the first spring member allows the second spring member.

Abstract
Description
Die Erfindung betrifft Fußbodendielen. Als Fußbodendielen wird nachfolgend jeglicher Fußbodenbelag aufgefasst, bei dem mindestens zwei gleichartig aufgebaute Elemente miteinander in Eingriff gebracht werden.The invention relates to floorboards. As floorboards is subsequently any Floor covering construed in which at least two identically constructed elements be engaged with each other.
Beispiele für die im Rahmen der Erfindung beanspruchten Fußbodendielen sind unter anderem Fertigparkett mit einer Nutzschicht, die nach Art eines Schiffsbodenparketts oder nach Art einer Landhausdiele gestaltet ist. Zu den Fußbodendielen zählen ebenfalls Dreischichtdielen, die aus drei etwa gleich starken Schichten, vorzugsweise aus Massivholz oder Furnier aufgebaut sind. Fußbodendielen, die im Rahmen der Erfindung beansprucht werden, sind häufig aus drei Schichten aufgebaut. Beispiele hierfür sind Fertigparkett mit einer dünnen Nutzschicht aus Furnier oder Massivholz, einer Mittellage aus verleimten oder unverleimten Stäben und einer Gegenzuglage aus minderwertigem Furnier oder Massivholz. Die Schichten sind mit der Hauptfaserrichtung ca. 90° zueinander versetzt, um maximale Dimensionsstabilität zu erreichen. Schichtdielen sind in der Regel aus drei etwa gleich starken und qualitativ etwa gleichwertigen Lagen von Massivholz bzw. Furnier aufgebaut. Furnier oder Stablagen sind bei einzelnen Produkten auch durch Holzwerkstoffschichten bzw. -platten zu ersetzen.Examples of claimed in the invention floorboards are under other prefabricated parquet with a wear layer, the manner of a Schiffsbodenparquet or designed in the manner of a plank. The floorboards also count Three-layer planks, consisting of three layers of approximately equal thickness, preferably solid wood or veneer are constructed. Floor boards, in the context of the invention are often composed of three layers. examples for this are Prefabricated parquet with a thin layer of veneer or solid wood, a central layer made of glued or glued sticks and a counterpoise of inferior Veneer or solid wood. The layers are about 90 ° with the main fiber direction offset to each other to achieve maximum dimensional stability. Layered boards are usually of three approximately equally strong and qualitatively approximately equal layers of Solid wood or veneer built. Veneer or bar racks are on individual products also by wood material layers or plates to replace.
Nachdem Fertigparkett bzw. Fußbodendielen zunächst als Produkte angeboten wurden, die miteinander zu verleimen sind, steigt mittlerweile die Nachfrage nach Fußbodendielen, die ohne Leimzugabe formschlüssig miteinander verbunden werden können. Während Profile für die Längsseiten von Fußbodendielen verhältnismäßig zügig entwikkelt wurden, besteht nach wie vor Bedarf an Profilen, die insbesondere geeignet sind, Fußbodendielen stirnseitig miteinander zu verbinden. Bei stirnseitigen Verbindungen sind unverhältnismäßig hohe Kräfte durch das holztypische Schwinden und Quellen und durch die in der Regel sehr langen Dielenelemente zu berücksichtigen.After ready-made parquet or floorboards were initially offered as products, which are to be glued together, the demand for flooring now rises, which can be positively connected with each other without adding glue. While profiles for the long sides of floorboards develop relatively quickly there is still a need for profiles that are particularly suited to Floor boards to connect frontally with each other. For frontal connections are disproportionately high forces due to the wood-typical shrinkage and swelling and to take into account by the usually very long plank elements.
Bekannt ist die in der DE 100 01 076 vorgeschlagene Lösung, die jedoch durch tiefe Einschnitte eine deutliche Schwächung der Fußbodendiele erfordert. Known is the proposed in DE 100 01 076 solution, but by deep cuts a significant weakening of the floorboard requires.
Weiter wird in der WO 00/47841 vorgeschlagen, Fußbodenpaneele allseitig mit einem Profil zu versehen, bei dem eine senkrecht zur Plattenebene zu schließende Verbindung vorgeschlagen ist, die Nut, Feder und Verriegelungselemente vorsieht. Die Verriegelungselemente sollen eine waagerechte Anlagefläche haben und ein Verschieben der Fußbodenpaneele senkrecht zur Plattenebene verhindern. Die Verriegelungselemente sollen elastisch ausgebildet sein. Nachteilig an dieser Lösung ist es, dass entweder gesonderte Bauteile eingelegt oder eingeleimt werden müssen, die Teile der Verriegelungselemente darstellen und die zum exakten Verriegeln sehr präzise positioniert werden müssen. Dies ist verarbeitungsaufwändig. Weiter ist nachteilig, dass die Verriegelungselemente beim Zusammenfügen leicht beschädigt werden können, wenn sie auf die in der WO 00/47841 vorgeschlagene Weise horizontale Anlageflächen aufweisen.Further, WO 00/47841 proposes floor panels on all sides with a Provide profile, in which a perpendicular to the plate plane to be closed connection is proposed, which provides groove, spring and locking elements. The locking elements should have a horizontal contact surface and a shifting of the Prevent floor panels perpendicular to the board plane. The locking elements should be elastic. The disadvantage of this solution is that either separate Components must be inserted or glued, the parts of the locking elements and which are positioned very precisely for exact locking have to. This is laborious. Another disadvantage is that the locking elements when joining can be easily damaged when on the in WO 00/47841 proposed manner have horizontal contact surfaces.
Es ist daher Aufgabe der Erfindung, ein Profil zum senkrechten Verbinden von mindestens zwei Fußbodenpaneelen vorzuschlagen, das einfach herzustellen und sicher zu betätigen ist.It is therefore an object of the invention to provide a profile for vertical connection of at least To propose two floor panels that are easy to make and secure Press is.
Diese Aufgabe wird gelöst durch ein Profil gemäß Anspruch 1 der Erfindung. Das Profil zum senkrechten Verbinden von mindestens zwei Fußbodenelementen, die jeweils mit einer Oberseite, einer Unterseite, zwei Längsseiten und zwei Stirnseiten versehen sind, weist folgende Gestaltungsmerkmale auf:
- eine Nut, die an einer ersten Stirnseite eines Fußbodenelements angebracht ist;
- eine Feder, die an einer zweiten Stirnseite eines Fußbodenelements angebracht ist, und
- an Nut und Feder angeordnete, korrespondierende Verriegelungselemente, die mindestens zwei zu verbindende Fußbodenelemente in ihrer vertikalen Zuordnung festlegen, weiter weisen
- die Verriegelungselemente schräg angeordnete Anlageflächen auf, und
- entweder die Feder des Profils oder Nut und Feder sind elastisch verformbar.
- a groove attached to a first end face of a floor member;
- a spring which is attached to a second end face of a floor element, and
- arranged on tongue and groove, corresponding locking elements that define at least two to be connected floor elements in their vertical assignment, further points
- the locking elements obliquely arranged contact surfaces, and
- either the spring of the profile or tongue and groove are elastically deformable.
Gegenüber dem vorgenannten Stand der Technik wurden wesentliche Änderungen vorgenommen, die sich zum einen auf die Ausbildung der korrespondierende Verriegelungselemente beziehen. Diese üblicherweise als Rastnase und korrespondierende Ausnehmung ausgebildeten Elemente wirken jeweils zusammen und legen die zu verbindenden Fußbodenelemente gegeneinander in vorgegebener Stellung fest. In der Regel verhindern sie bei senkrecht zu schließenden Profilen ein Verschieben vertikal zur Ebene des Fußbodenelements bzw. der Oberfläche des Fußbodenelements. Die korrespondierenden Verriegelungselemente weisen deshalb eine gemeinsame Anlagelinie oder - fläche auf. Anders als im Stand der Technik, bei dem eine waagerechte, also parallel zur Oberseite des Fußbodenelements verlaufende Anlagefläche vorausgesetzt wurde, hat sich im Zusammenhang mit dem erfindungsgemäßen Profil ergeben, dass schon eine einfach schräg gestellte Anlagefläche genügt, um ein sicheres Verriegeln zu gewährleisten. Gleichzeitig ermöglicht eine schräge Anlagefläche ein einfacheres und für die Verriegelungselemente schonenderes Zusammenfügen des Profils und damit der Fußbodenelemente.Compared to the aforementioned prior art, significant changes have been made, on the one hand to the formation of the corresponding locking elements Respectively. These usually as latching lug and corresponding recess trained elements act together and put the to be joined Floor elements firmly against each other in a predetermined position. Usually In the case of profiles that are to be closed vertically, prevent them from moving vertically to the plane the floor element or the surface of the floor element. The corresponding ones Locking elements therefore have a common investment line or - surface on. Unlike in the prior art, in which a horizontal, ie parallel to the The upper side of the floor element has been assumed to have running contact surface arise in connection with the profile of the invention, that already a simply inclined contact surface is sufficient to ensure a secure locking. At the same time an inclined contact surface allows a simpler and for the locking elements more gentle assembly of the profile and thus the floor elements.
Die elastische Verformbarkeit von Feder oder Nut und Feder, also das Auslenken von Feder oder Nut und Feder beim Zusammenfügen des Profils bzw. zweiter Fußbodenelemente tragen ebenfalls zur Schonung der Verriegelungselemente sowie von Nut und Feder bei. Das Auslenken der Feder oder von Nut und Feder schont die korrespondierenden Verriegelungselemente, wenn sie beim Zusammenfügen der Fußbodendielen miteinander in Eingriff gebracht werden.The elastic deformability of spring or tongue and groove, so the deflection of Spring or tongue and groove when joining the profile or second floor elements also contribute to the protection of the locking elements and of the groove and spring at. The deflection of the spring or tongue and groove protects the corresponding Locking elements when joining the floorboards be engaged with each other.
Die zu verbindenden Fußbodenelemente bzw. -dielen werden in ihrer horizontalen Stellung zueinander besonders wirksam festgelegt, wenn Nut und Feder als Konus ausgebildet sind. Diese formschlüssige Verbindung des Profils fixiert die beiden Fußbodendielen auf einfache und sichere Weise. Die Konizität von Nut und Feder kann beibehalten werden, auch wenn korrespondierende Verriegelungselemente oder besondere Ausführungsformen von Nut und Feder vorzusehen sind. Es genügt, wenn Nut und Feder mindestens abschnittsweise zum konischen Eingriff ausgelegt sind.The floor elements or floorboards to be joined are in their horizontal Position set particularly effective to each other when tongue and groove formed as a cone are. This positive connection of the profile fixes the two floorboards in a simple and secure way. The conicity of tongue and groove can be maintained be, even if corresponding locking elements or special Embodiments of tongue and groove are provided. It is enough if tongue and groove at least partially designed for conical engagement.
Nach einer vorteilhaften Ausführungsform ist die Feder des Profils so ausgearbeitet, dass sie beim Zusammenfügen des Profils ausgelenkt wird, um dann nach dem erfolgten Eingriff von Nut und Feder wieder die Ausgangsstellung einzunehmen. Diese Elastizität lässt sich herstellen, indem der erforderliche Freiraum, der für den Eingriff einer Lippe der Nut erforderlich ist, so tief ausgearbeitet wird, dass der verbleibende Verbindungssteg zum Profil bzw. zum Fußbodenelement ein Auslenken der Feder ermöglicht. Diese Ausführungsform erweist sich als vorteilhaft, weil zum einen keine Auslenkung an der Unterseite des Profils erfolgt, so dass es sich erübrigt, Maßnahmen zu ergreifen, die ein solches Auslenken in Richtung auf die Unterlage der Fußbodendielen gestatten. Zum anderen bewirkt diese Ausführungsform, dass die Bildung von unerwünschten Fugen zwischen den Stirnseiten zweiter Fußbodenelemente vermieden wird.According to an advantageous embodiment, the spring of the profile is designed so that that it is deflected when joining the profile, and then after that Engagement of tongue and groove again assume the starting position. This elasticity can be made by giving the required clearance for the engagement of a lip the groove is required, so deeply worked out that the remaining connecting bar allows the profile or the floor element deflecting the spring. These Embodiment proves to be advantageous because on the one hand no deflection at the Bottom of the profile is done so that it is unnecessary to take any action allow such deflection towards the base of the floorboards. To the Another effect of this embodiment is that the formation of unwanted joints between the end faces second floor elements is avoided.
Gemäß einer besonders bevorzugten Ausführungsform ist die Feder des Profils zweiteilig ausgebildet. Ein erstes Federteil ist elastisch ausgebildet, ein zweites Federteil ist starr ausgebildet. An dem elastischen ersten Federteil ist ein erstes Teil eines korrespondierenden Verriegelungsmittel angeordnet. Der große Vorteil der zweigeteilten Feder liegt darin, dass die Verformungsvorgänge beim Zusammenfügen des Profils nicht dazu führen, dass Nut oder Feder oder Teile davon sich beim Zusammenfügen über Ober- oder Unterseite der Fußbodenelemente hinaus verschieben.According to a particularly preferred embodiment, the spring of the profile is in two parts educated. A first spring part is elastic, a second spring part is rigidly formed. On the elastic first spring part is a first part of a corresponding Locking means arranged. The big advantage of the two-part spring is that the deformation processes when joining the profile not cause the tongue or groove or parts thereof when joining over Move the top or bottom of the floor elements out.
Allgemein kann das elastische erste Federteil so ausgebildet sein, dass ein Verformen und Auslenken während des Zusammenfügen des Profils ermöglicht ist. Bevorzugt wird aber, wenn zwischen erstem und zweiten Federteil ein Freiraum geschaffen wird, der ein Auslenken des ersten Federteils auf das zweite Federteil zu ermöglicht. Diese Ausführungsform ist mittels üblicher Werkzeuge und Verfahren herzustellen, z. B. zu Fräsen. Der Freiraum kann sich -bezogen auf die Oberseite eines Fußbodenelements- etwa rechtwinklig oder auch schräg erstrecken. Die exakte Ausgestaltung des Freiraums kann in Abstimmung zum verwendeten Material des Profils und zum Profil selbst gewählt werden.Generally, the elastic first spring member may be formed so that a deformation and deflecting while assembling the profile. It is preferred but if between the first and second spring part a free space is created, the a deflection of the first spring member allows the second spring member. This embodiment is to produce by conventional tools and methods, for. B. to milling. The space may be - related to the top of a floor element - about extend at right angles or at an angle. The exact design of the free space can chosen in coordination with the material used for the profile and the profile itself become.
Eine Ausführungsform des erfindungsgemäßen Profils, mit der ein fugenfreies Zusammenfügen der Stirnseiten von Fußbodenelementen auf einfache Weise gewährleistet werden kann, ist so ausgebildet, dass die Feder ein erstes Teil eines korrespondierenden Verriegelungselementes aufweist, dass mit einem zweiten Teil des korrespondierenden Verriegelungselementes in Eingriff gebracht werden kann. Dieses zweite Teil des korrespondierenden Verriegelungselementes ist an einer kurzen, freien Lippe der Nut angebracht und weist zur Feder hin. An embodiment of the profile according to the invention, with a joint-free assembly ensures the front sides of floor elements in a simple manner is designed so that the spring is a first part of a corresponding Locking element has that with a second part of the corresponding Locking element can be engaged. This second part of the corresponding Locking element is attached to a short, free lip of the groove and points to the spring.
Das erfindungsgemäße Profil erfordert eine gewisse Elastizität des Materials. Spröde Werkstoff wie z. B. hochdichte Faserplatten oder Werkstoffe mit geringer Biegefestigkeit wie z. B. Spanplatten, eignen sich nicht gut für die Herstellung des vorbeschriebenen Profils. Es wird deshalb bevorzugt, wenn Kunststoff, Massivholz oder Sperrholz zur Herstellung des Profils verwendet werden. Diese Materialien weisen bei guter Bearbeitbarkeit mit bekannten Werkzeugen eine ausreichende Elastizität auf, um das zuverlässige Funktionieren des Profils zu gewährleisten.The profile according to the invention requires a certain elasticity of the material. Brittle Material such. As high density fiberboard or materials with low bending strength such as As chipboard, are not well suited for the production of the above Profile. It is therefore preferred if plastic, solid wood or plywood for Production of the profile can be used. These materials have good machinability with known tools on a sufficient elasticity to the reliable Ensuring the functioning of the profile.
Das erfindungsgemäße Profil kann, je nach Bedarf, entweder als separates Bauteil vorgefertigt werden, um dann an Stirnseiten von Fußbodenelementen angebracht zu werden, beispielsweise durch Einkleben in eine Nut in der Stirnseite. Eignet sich das Material des Fußbodenelements, z. B. im Fall einer Massivholz-Fußbodendiele, dann kann das erfindungsgemäße Profil integral aus dem Werkstoff des Fußbodenelements herausgefräst werden.The profile according to the invention can, depending on requirements, either prefabricated as a separate component be mounted on end faces of floor elements, for example, by gluing in a groove in the front.

Fig. 1a zeigt eine nutförmige Stirnseite 2 einer Fußbodendiele 1 sowie eine federförmige
Stirnseite 4 einer Fußbodendiele. Es stehen - wie nachstehend erläutert wird - nach
dem Verlegen der Fußbodendielen stets eine nutförmige und eine federförmige Stirnseite
von zwei Fußbodendielen miteinander im Eingriff. Entsprechend weist eine Fußbodendiele
1 jeweils eine erste nutförmige Stirnseite 2 und eine zweite federförmige
Stirnseite 4 auf. Die Fußbodendiele ist dreischichtig aufgebaut. Die gestrichelten Linien
in den Fig. deuten die drei Lagen der Fußbodendiele an. Sie weist an der Oberseite 6
eine Nutzschicht auf. Die Unterseite 8 der Fußbodendiele kann aus beliebigem Material
bestehen.Fig. 1a shows a groove-shaped
Die nutförmige Stirnseite 2 weist eine Nut 10 mit einer langen Lippe 12 und einer kurzen
Lippe 14 auf. Die Lippen 12, 14 der Nut 10 sind durch die Basis 16 miteinander verbunden.
Die Nut 10 wird von der Oberseite 6 der Fußbodendiele 1 her ausgearbeitet, in
der Regel ausgefräst.The groove-shaped
Die federförmige Stirnseite weist eine Feder 18 auf, die durch einen Freiraum 20 von
der Stirnfläche 22 der Fußbodendiele 1 abgegrenzt ist. Die Feder 18 wird von der Unterseite
8 der Fußbodendiele 1 her ausgearbeitet, in der Regel ausgefräst.The spring-shaped end face has a
Aus Fig. 1b ist zu entnehmen, dass beim Ineinanderfügen von Nut 10 und Feder 18 die
freie Fläche der langen Lippe 12 und die freie Fläche 24 der Feder 18 einander zugewandt
sind. Das freie Ende 26 der Feder 18 ist der Basis 16 der Nut 10 zugewandt. Die
kurze Lippe 14 der Nut 10 ragt in den Freiraum 20 der federförmigen Stirnseite 4 hinein.From Fig. 1b it can be seen that when joining
Fig. 1c zeigt die nutförmige Stirnseite 2 und die federförmige Stirnseite 4 der Fußbodendielen
1 miteinander im Eingriff. Die dem Freiraum 20 zugewandte Fläche 28 der
Feder 18 liegt an der der langen Lippe 12 zugewandten Fläche 30 der kurzen Lippe 14
an. Das freie Ende 26 der Feder 18 ist der Basis 16 der Nut 10 zugewandt, liegt aber
nicht zwingend an der Basis 16 an. Das freie Ende 32 der kurzen Lippe 14 ist der
Grundfläche 34 des Freiraums 20 zugewandt, liegt aber nicht zwingend an der Grundfläche
34 an.Fig. 1c shows the groove-shaped
Dort, wo die Feder 18 mit der dem Freiraum 20 zugewandte Fläche 28 an der Fläche 30
der kurzen Lippe 14 anliegt, wird eine Druckfläche 36 gebildet. Ausgehend von der
Druckfläche 36 wird eine Druckkraft auf die Anlagefläche 38 ausgeübt, die dadurch gebildet
wird, dass die nutförmige und die federförmige Stirnseite 2, 4 der Fußbodendiele
1 an der Oberseite 6 aneinander anliegen. Sowohl die Druckfläche 36 als auch die Anlagefläche
38 können punkt- oder linienförmig ausgebildet sein. Bevorzugt sind die Flächen
36, 38 aber auch tatsächlich flächig ausgebildet.There, where the
Um das Zusammenfügen der Stirnseiten 2, 4 der Fußbodendielen 1 zu erleichtern, ist
das freie Ende 26 der Feder 18 schmaler ausgebildet als die Basis 16 der Nut 10. Weiter
sind zum einfacheren Zusammenfügen der Stirnseiten 2, 4 das freie Ende 26 der Feder
18, das freie Ende 32 der kurzen Lippe 14 der Nut 10 sowie die Grundfläche 34 des Freiraums
20 am Übergang zu angrenzenden Flächen jeweils mit gerundeten oder gebrochenen
bzw. gefasten Kanten ausgebildet. Entsprechend sind die Stirnfläche 22 des
Freiraums 20 und die Abschlussfläche 40 der kurzen Lippe 14 der Nut 10 nach dem Zusammenfügen
im Abstand voneinander angeordnet.To facilitate the joining of the end faces 2, 4 of the
Um eine möglichst große Anlagefläche 38 zu erzielen, ist die freie Fläche 24 der Feder
18 in der Weise gestaltet, dass sie in einem ersten Abschnitt 42 im Bereich der Oberseite
6 der Fußbodendiele 1 weiter auskragt als in einem zweiten Abschnitt 44 im Bereich der
Mittellage 46 der Fußbodendiele 1. Entsprechend weist die Außenfläche der langen
Lippe 12 der nutförmigen Stirnseite 4 im Bereich der Oberseite 6 der Fußbodendiele 1
einen ersten Abschnitt 48 auf, der weiter ausgenommen ist als die Basis 16 der Nut 10.
An diesen ersten Abschnitt 48 schließt sich zur Basis 16 der Nut 10 ein zweiter Abschnitt
50 an, der etwa rechtwinklig zur Basis 16 der Nut 10 verläuft.In order to achieve the largest
Fig. 1c zeigt, dass die Abschnitte 42, 44 und 48, 50 korrespondierend zueinander ausgearbeitet
sind. Das Zusammenfügen der beiden Stirnseiten 2, 4 wird dadurch sehr erleichtert.Fig. 1c shows that the
Fig. 1c verdeutlicht weiter, dass die Anlagefläche 38 gut besser definiert ist. Da die Anlagefläche
38 das optische Erscheinungsbild und den qualitativen Eindruck der verlegten
Fußbodendielen wesentlich bestimmt, wird mit den erfindungsgemäßen Profilen, die
außerordentlich einfach herstellbar sind, der gewünschte, von den Kunden mit Holzfußböden
assoziierte hochwertige, weil fugenarme Eindruck vermittelt.Fig. 1c further illustrates that the
Die vorstehend erläuterten Ausführungen der erfindungsgemäß profilierten Fußbodendielen
1 bewirken mit einer einfachen Ausbildung von Nut und Feder eine überraschend
zuverlässige, fugendichte Verbindung der Stirnseiten zweier miteinander im Eingriff
stehender Fußbodendielen. Gleichzeitig wird durch das Erzeugen von Druckkräften verhindert,
dass die Fußbodendielen sich in senkrechter Richtung -bezogen auf die Ober-
bzw. Unterseite der Fußbodendielen- nach dem Zusammenfügen verschieben.The above-explained embodiments of the invention profiled
Fig. 1a zeigt eine besonders bevorzugte Ausführungsform der erfindungsgemäß profilierten
Fußbodendielen, bei denen durch die Gestaltung der Feder 18 das Aufbringen
der Druckkraft auf die Anlagefläche 38 und das Verhindern des Verschiebens der Stirnflächen
2, 4 in senkrechter Richtung durch eine zweigeteilte Feder 18a, 18b bewirkt ist.Fig. 1a shows a particularly preferred embodiment of the invention profiled
Floor boards, where by the design of the
Von der Unterseite 8 der Fußbodendiele 1 her wird ein erster Freiraum 20a ausgearbeitet,
an den sich eine erste Feder 18a anschließt. Die Feder 18a weist eine zum Freiraum
20 hin gerichtete Fläche 28 auf, die nach dem Zusammenfügen der Fußbodendielen 1
mit der zur langen Lippe 12 hin gerichteten Fläche 30 der kurzen Lippe 14 in Eingriff
kommt. Die erste Feder 18a ist so ausgebildet, dass sie beim Zusammenfügen der nutförmigen
Stirnseite 2 und der federförmigen Stirnseite 4 kaum ausgelenkt wird. Zum
freien Ende 52 der federförmigen Stirnseite 2 schließt sich an die Feder 18a ein Freiraum
20 b an, der zum freien Ende 52 hin von einer zweiten Feder 18b begrenzt ist. Der
Freiraum 20b ragt näher an die Oberseite 6 der Fußbodendiele 1 heran als der Freiraum
20a.From the
Die Feder 18b ist gegenüber der Feder 18a beim Zusammenfügen der Stirnseiten 2, 4
auslenkbar (siehe Fig. 1b). Zum Zwischenraum 20b hin ist die Feder 18b mit einer geraden
Fläche 54 gestaltet. Zum freien Ende 52 hin ist die Feder 18b an ihrem freien Ende
26b mit einer Rastnase 56 versehen.The spring 18b is opposite to the
Die Nut 10 ist im Bereich der langen Lippe 12 mit einem Riegel 58 versehen, unter dem
die Rastnase 56 der Feder 18b nach dem Zusammenfügen der Fußbodendielen 1 einrastet.
Damit ergibt sich nach dem Zusammenfügen der nutförmigen Stirnseite 2 und der
federförmigen Stirnseite4 der Fußbodendielen 1 neben der ersten Anlagefläche 38 eine
zweite Anlagefläche 60, die jedoch -bezogen auf die Ober- bzw. Unterseite 6,8 der Fußbodendiele
1- schräg ausgerichtet ist (siehe Fig. 1c). Durch die Anlagefläche 60 wird ein
Verschieben der Fußbodendielen 1 gegeneinander verhindert. Der Freiraum 20 b ist so
dimensioniert, dass die Feder 18b beim Zusammenfügen durch den Riegel 58 ausgelenkt
werden kann. Das fugendichte Zusammenfügen der nutförmigen 2 und federförmigen4
Stirnseiten wird -wie bei den zuvor beschriebenen Ausführungsformen der Fig.
1-3- durch die Feder 18a und die kurze Lippe 14, durch die die Druckfläche 36 ausgebildet
ist, gewährleistet.The
Die in den Fig. 2a bis 2c dargestellte Ausführungsform ist besonders vorteilhaft für Fußbodendielen, die mehrfach zusammengefügt und auseinandergenommen werden sollen, beispielsweise für temporär verlegte Fußböden in Messe- oder Ausstellungshallen. Es handelt sich um eine Ausführungsform, die ausgehend von der in Fig. 1a bis 1c dargestellten Variante entwickelt wurde.The embodiment shown in FIGS. 2a to 2c is particularly advantageous for Floorboards that are assembled and dismantled several times should, for example, for temporarily laid floors in exhibition or exhibition halls. It is an embodiment which, starting from the in Fig. 1a to 1c variant has been developed.
Die nutförmige Stirnseite 2 weist eine Nut 10 auf, deren Nutgrund 16 verhältnismäßig
flach ausgebildet ist, so dass eine stärkere Materialschicht auf der Unterseite 8 der Fußbodendiele
1 verbleibt. Entsprechend ist die kurze Lippe 14 der Nut 10 bezogen auf den
Nutgrund 16 weniger hoch als bei der in Fig. 1a bis 1c gezeigten Ausführungsform. Die
kurze Lippe 14 der Nut 10 ragt, bezogen auf die Dicke der Fußbodendiele 1, vorzugsweise
nicht in die obere Hälfte der Fußbodendiele 1 hinein. Die lange Lippe 12 ist mit einem
Riegel 58 ausgestattet, der nach dem Zusammenfügen der korrespondierenden Enden
der Fußbodendielen mit einer Rastnase 56 der Feder 18b im eingriff steht.The groove-shaped
Die Federn 18a und 18b sind korrespondierend zu den Abmessungen der Nut 10 ausgebildet.
Der Freiraum 20a ist mit Rücksicht auf die in der Höhe reduzierten kurzen Lippe
14 weniger tief ausgearbeitet. Dies kommt der Stabilität der Fußbodendiele zugute. Der
Freiraum 20 b ist dagegen unverändert tief eingeschnitten, um ein Auslenken der Feder
18b beim Zusammenfügen der Fußbodendielen zu ermöglichen (vg. Fig. 5b).The
Fig. 2c zeigt die Fußbodendielen nach dem Zusammenfügen. Druckfläche 36 und Anlagefläche
38 sind nach Art eines Konus zusammengefügt. Rastnase 56 und Riegel 58 liegen
an der zweiten Anlagefläche 60 aneinander an. Zwischen der Feder 18b und der Nut
10 ist unterhalb der zweiten Anlagefläche 60 ein Freiraum 62 vorgesehen. Die Feder 18b
ist entsprechend kurz dimensioniert. Dies erleichtert zum einen das Zusammenfügen
und Lösen der Fußbodendielen 1 voneinander. Zum anderen wird ein unnötiges und
unerwünschtes Klemmen oder eine Reibung durch Staub oder Schleif- bzw. Fräsrückstände
in der Nut 10 vermieden.Fig. 2c shows the floorboards after assembly.
Die Feder 18a ist ebenfalls nur mit einer verhältnismäßig klein bemessenen Auflagefläche
64 auf dem Nutgrund 16 abgestützt. Die Auflagefläche 64 ist -und dies gilt für alle
vorstehend beschriebenen Profile- nur so groß bemessen, dass eine Ausrichtung der
Fußbodendielen der Höhe nach gewährleistet ist. Ansonsten ist ein Freiraum unterhalb
der Feder 18a zum Nutgrund hin vorgesehen.The
Trotz der komplexen Aufteilung der Funktionen ist das Profil der in Fig. 1a bis 1c und 2a bis 2c dargestellten Fußbodendiele einfach herzustellen. Es sind nur wenige, gut herstellbare Hinterschneidungen auszuarbeiten.Despite the complex distribution of functions, the profile of the in Fig. 1a to 1c and 2a to 2c illustrated floorboard easy to make. There are only a few, easy to produce To work out undercuts.
Es wird festgehalten, dass die vorbeschriebene, als erfindungswesentlich angesehene
Trennung der Funktionen (Sichern gegen eine Längsverschiebung der Fußbodendielen
und Sichern gegen eine Höhenverschiebung der Fußbodendielen) nach dem Prinzip der
Konusklemmung einerseits und der Verrastung mittels einer Feder andererseits auch in
ganz anderer Anordnung des Profils ausgeführt werden kann. So ist es beispielsweise
vorstellbar, dass die Verrastung im Bereich der kurzen Lippe der Nut erfolgt oder das
eine Verrastung zwischen der kurzen Lippe der Nut und der federförmigen Stirnseite
der Fußbodendiele erfolgt:
Diese Ausführungsform bietet den Vorteil, dass eine nahezu fugenfreie Anlage der Stirnseiten von zwei im Eingriff befindlichen Fußbodenelementen gewährleistet wird.This embodiment offers the advantage that a virtually joint-free installation of End faces of two engaging floor elements is ensured.
Falls es das Material insbesondere der Mittellage der Fußbodendiele nicht erlaubt, die erfindungsgemäßen Profile auszuarbeiten, bietet sich folgendes Verfahren an:If the material, in particular the middle layer of the floorboard, is not allowed, the To work out profiles according to the invention, the following method is available:
Beim Legen der Mittellage ist die Länge der herzustellenden Dielen bekannt. Jeweils im Bereich der Stirnseiten wird statt des nicht zum Herstellen der Profile geeigneten Materials ein hochwertiges Material eingelegt, dass ein Herausarbeiten des Profils ermöglicht. Dieses Material kann Holz, Kunststoff oder Metall oder ein anderes zum Herstellen des Profils und zur Aufnahme der entstehenden Kräfte geeignetes Material sein. Damit ist ein erfindungsgemäßes Profilieren der Stirnseiten der Fußbodendielen möglich.When laying the middle layer, the length of the boards to be produced is known. Each in the Area of the end faces is used instead of not suitable for the manufacture of the profiles material a high quality material inserted that allows working out of the profile. This material can be wood, plastic or metal or another for manufacturing the profile and to absorb the resulting forces suitable material. For an inventive profiling of the front sides of the floorboards is possible.
Alternativ kann nach dem Herstellen der an den Stirnseiten noch unbearbeiteten Fußbodendielen eine Ausnehmung geschaffen werden, die die das vorbeschriebene, zur Herstellung der Profile geeignete Material eingefügt und mit der Fußbodendiele verbunden wird. Auch auf diese Weise wird eine profilierbare Stirnseite der Fußbodendiele hergestellt. Alternatively, after making the floorboards still unprocessed floorboards a recess are created, which the above, the Making the profiles suitable material inserted and connected to the floorboard becomes. Also in this way is a profilierbare front side of the floorboard produced.
Schließlich kann bei dem zuletzt beschriebenen Verfahren auch ein bereits profiliertes Material eingesetzt werden.Finally, in the method last described, an already profiled Material are used.
Die erfindungsgemäß vorgeschlagene Verbindung weist eine Anlagefläche zwischen der nutförmigen Stirnseite und der federförmigen Stirnseite der Fußbodendiele im Bereich der Nutzschicht und einen Druckpunkt auf, der im Bereich zwischen der Basis der Nut und der kurzen Lippe der Nut, die an der Stirnseite der Fußbodendiele angeordnet ist einerseits und der Feder andererseits liegt. Durch den Druckpunkt, der zwischen Feder und kurzer Lippe der Nut gebildet wird, wenn zwei korrespondierende Stirnseiten der Fußbodendielen miteinander in Eingriff gebracht werden, wird gewährleistet, dass die Anlagefläche zwischen der nutförmigen und der federförmigen Stirnseite der beiden Fußbodendielen unter Drucklast steht, so dass eine Fugenbildung oder ein Lösen der beiden Fußbodendielen ausgeschlossen ist. Die Feder greift nach dem Zusammenfügen als Konus klemmend in die Nut ein und bewirkt so eine Fixierung der Fußbodendielen zueinander. Diese Art der Konusklemmung ist einfach und wirksam.The invention proposed compound has a contact surface between the groove-shaped end face and the spring-shaped end face of the floorboard in the area the wear layer and a pressure point in the area between the base of the groove and the short lip of the groove, which is arranged on the front side of the floorboard on the one hand and the spring on the other. By the pressure point between spring and short lip of the groove is formed when two corresponding end faces of the Floorboards are engaged with each other, ensures that the Contact surface between the groove-shaped and the spring-shaped end face of the two Floor boards under pressure, so that a gap formation or a release of the is excluded from both floorboards. The spring engages after assembly as a cone clamped in the groove and thus causes a fixation of the floorboards to each other. This type of cone clamping is simple and effective.
Nach einer bevorzugten Ausführungsform der Erfindung ist die Stirnfläche der Feder, die der nutförmigen Stirnseite zugewandt ist, mit einer Stufe versehen. Am weitesten kragt die Anlagefläche aus, die an der langen Lippe der Nut im Bereich der Nutzfläche angeordnet ist. Unterhalb der Anlagefläche, zum freien Ende der Feder hin, ist die Stirnfläche der Feder schmaler ausgebildet, so dass eine zurückspringende Stufe gebildet ist. Die der Feder zugewandte Fläche der langen Lippe der Nut ist korrespondierend geformt. Unterhalb der Anlagefläche ist ein Vorsprung ausgebildet, deren Abmessungen etwa den Abmessungen der zurückspringenden Stufe der Feder entsprechen.According to a preferred embodiment of the invention, the end face of the spring, which faces the groove-shaped end face, provided with a step. The furthest cantilevers the contact surface, which at the long lip of the groove in the area of the usable area is arranged. Below the contact surface, towards the free end of the spring, is the Face of the spring formed narrower, so that a recessed step formed is. The spring-facing surface of the long lip of the groove is corresponding shaped. Below the contact surface, a projection is formed whose dimensions approximately correspond to the dimensions of the recessed level of the spring.
Bei der vorstehend beschriebenen Ausführungsform ist die Anlagefläche besonders breit ausgebildet, so dass die Vorgabe, einen stirnseitig spaltfreien Anschluss der Fußbodendielen aneinander zu gewährleisten, sicher erfüllt ist.In the embodiment described above, the contact surface is particularly wide designed so that the requirement, a front-side gap-free connection of the floorboards to ensure each other is safely fulfilled.
Die vorstehende Beschreibung bezieht sich vorwiegend auf die Gestaltung der Stirnseiten von Fußbodendielen. Bei Bedarf können aber auch die Längsseiten von Fußbodendielen entsprechend gestaltet sein.The above description relates primarily to the design of the end faces of floorboards. If necessary, but also the long sides of floorboards be designed accordingly.
