Definitions
- the present invention relates to a panel, in particular floor panel, such as laminate flooring; Engineered flooring; Veneer floor or Korkpaneel, with a tongue and groove connection according to the preamble of claim 1.
- floor panel such as laminate flooring; Engineered flooring; Veneer floor or Korkpaneel
- the features contained in the preamble of claim 1 are from the US-B-5,295,341 known.
- a panel is out of the EP 1 128 000 A2 which corresponds to the post-published state of the art according to Art. 54 (3) EPC.
- the spring has a parallel to the top of the panel extending slot and the groove has a wedge-shaped projection in the groove base, which engages in mated panels in the slot.
- the tip of the wedge-shaped projection lies at the height of the slot in the spring and engages in the mating of two panels in the slot and forces the two spring parts to the outside.
- Another tongue and groove connection is from the DE 299 22 649 U1 known.
- the catch contour is formed in this known panel by a trapezoidal in cross-section elevation, which engages in the connected state of two panels in a counter-shaped recess.
- the survey is provided on the underside of the single spring, while the associated recess in the lower part of serving to accommodate the single spring single Groove is attached.
- a disadvantage is considered in this connection that in the region below the groove, the panel has a relatively thin and relatively far projecting protrusion that can be easily deformed or damaged during transport and other handling of the panel. As a result, the function of the tongue and groove connection can be hindered or even prevented.
- a tongue and groove connection which also each comprises a tongue and groove.
- the locking contour comprises a formed on one of the two panels, functionally separated from the tongue and groove connection locking pin, which can be brought into non-positive or positive engagement with an engagement element on the adjacent panel.
- a thermal insulation board which consists of at least two overlapping plate parts.
- On the plate parts holding and guiding devices for example in the form of two tongue and groove joints are provided so that the plate parts in the overlapping area against each other in one direction are displaced.
- the two tongue and groove joints are offset from each other in the direction of displacement of the two plates and allow a simple displacement of the plates, so as to adapt the width of the entire plate to the respective room conditions.
- a component for covering surfaces with surface elements, in particular wall and / or floor tiles which creates a protective against ingress of water into the ground surface.
- the component at opposite edges on a spring and a groove.
- the spring is provided on its spring tip with a receptacle and has on its underside two wells and on its upper side a trough, which are arranged offset from the spring tip.
- a stop lug and corresponding to the troughs surveys are provided in the groove corresponding to the recording of the spring. This allows a positive and non-positive, no water or moisture transmitting, releasable connection can be achieved.
- the object is to provide a panel of the initially mentioned type, which avoids the disadvantages set out and with the particular reliable and stable Connection of two adjacent panels is possible, with a height offset between the connected panels should be excluded.
- laying and connecting the panels together should be easy and simple.
- the locking contour is in the usually more stable upper portion of the panels, so that a high resistance to pulling apart of connected panels is achieved.
- the locking contour the joining of two panels in their laying advantageous in that a newly attached panel simply brought in the plane of the already laid panels to the last laid panel and then brought to its final investment in the already laid panel becomes.
- known per se clamping or pressing tools such as straps or block and hammer hammer can be used. Due to its design, the tongue and groove connection is very well suited for glueless laying of panels.
- connection is provided on the longitudinal edges of the panels.
- connection is expediently also provided on the front edges.
- the joining of two panels along the longitudinal edges can advantageously take place first. Thereafter, the last scheduled panel is still displaceable in its longitudinal direction, so that it can be brought easily by such a longitudinal displacement then at its front edge in engagement with the frontally adjacent, previously laid panel.
- the plane of the panel end surface from which the grooves or springs extend, at least in their panel upper side adjacent part at an angle a of less than 90 ° Top of the panel extends and that the panels in their connected state below their upper side viewed in the connecting direction at a distance from each other.
- a gap-free installation of the panels is facilitated, so that the risk of moisture seeping into the connection areas is avoided.
- the dense laying also remains if, within e.g. of a floor slight inclination changes are present, if these are not larger than the difference between the angle a and 90 °.
- the angle a is between 86 and 88 °, more preferably about 87 °. This relatively little deviating from the right angle angle a is sufficient to achieve the previously described gap freedom in the laid panels, at the same time the desired adaptability is retained on vaults of the ground.
- the depth of the gap between the springs reaches at most to the level of the panel edge of the associated panel.
- the gap is relatively easy to produce due to this limited depth; a greater depth of the gap than specified here is not required, since increasing the depth has no effect on the flexibility of the springs more.
- the web fills between 30 and 95% of the depth of the intermediate space.
- the determination of the percentage depends on the requirements of the connection, wherein a lower filling facilitates the subsequent separation of panels by tilting against each other, while on the other hand a greater degree of filling for a higher load capacity of the connection when using e.g. of the floor offers from these panels.
- the locking contour is preferably provided that this is formed by a triangular in cross section survey on the top of the upper spring on the one hand and by a gegen Dermate recess in the top of the associated upper groove on the other.
- this is formed by a triangular in cross section survey on the top of the upper spring on the one hand and by a gegen Dermate recess in the top of the associated upper groove on the other.
- the apex angle of the survey and the recess between 90 and 120 °, preferably about 105 °.
- the survey is formed with mutually symmetrical flanks.
- the force required to join the panels is substantially as great as the force required to pull the panels apart.
- an alternative in this regard embodiment provides that the survey is formed with mutually asymmetrical edges, the flank, which carries the spring Panel edge is facing, is flatter than the other flank of the survey. This design ensures that a smaller force is sufficient for the joining of the panels as the force that is applied for pulling apart two panels.
- the invention proposes that the upper spring from the panel top has a distance which is greater than the distance of the lower spring from the panel underside.
- This different spacing facilitates a later need-based separation of two panels by tilting against each other, because by the larger distance of the upper spring of the panel top here is already a relatively large radius of the lying in the surface of the panel top pivot axis to the upper spring. The larger this pivot radius, the less the spring is claimed in the tilting of the panels for the purpose of their separation, so that accordingly the risk of damage to the spring is smaller.
- the free end of the spring equipped with the locking contour or the free end of both springs is expedient starting from the bottom with a runner-shaped rounded.
- the invention also proposes that the flexibility of the connection between the panels by varying the depth of the grooves and / or the gap is variable.
- This offers the advantage that the ductility of the compound can also be subsequently influenced even with the manufacturer of the panels, since usually the panels are initially produced without grooves and feathers with smooth edges. The grooves and springs are then attached later in appropriate processing lines. Since the material properties of the panels per se after their production are no longer changeable, the ductility of the compound without changing the material properties of the panels can still be influenced in a desired manner by changing the depths mentioned, on the one hand to connect the panels as easily as possible to each other and order On the other hand, to give the panels a sufficiently strong cohesion even when glued laying.
- FIG. 1 shows on the left the right edge region of a first panel 1 and on the right the left edge region of a second panel 2.
- the two panels 1, 2 are connected to each other by means of a tongue and groove connection.
- the Laying order runs from left to right here; the panel 1 is therefore laid first and then the panel 2 attached to it.
- the tongue and groove connection here consists of a double groove with two grooves 21, 22 in the right panel 2 and a double spring with two springs 11, 12 on the left panel 1.
- the springs 11, 12 protrude from the panel 2 facing end face 10 of the first panel 1 before.
- the associated grooves 21, 22 lie in the end face 20 of the second panel 2 facing the first panel 1.
- a gap 13 Between the two springs 11, 12 is a gap 13. Between the two grooves 21, 22 is a web 23 which projects into the intermediate space 13. However, the height of the web 23 is smaller than the depth of the gap 13, so that the gap 13 is filled in the example shown only about half of the web 23 when the panels 1, 2, as shown here, are interconnected.
- the tongue and groove connection comprises a positive locking, which is formed by a latching contour.
- the locking contour here consists of a survey 14, which is provided on the upper flat side of the upper spring 11, and a counter-recessed recess 24, which is mounted on the upper side in the upper groove 21.
- the elevation 14 and the recess 24 are triangular in cross-section, wherein the apex angle ⁇ is about 105 ° here.
- the free end of the springs 11, 12 is, starting from each of its underside, executed with a runner-shaped rounded portion 15, which facilitates the joining of the panels 1, 2 and in particular also a need-later separation of the panels 1, 2.
- the free end of the web 23 is slightly rounded at its edges.
- the laid panels 1, 2 in their interconnected state on their top panel 16, 26 form a uniform and column-free surface, here is the end face 10 of the left panel 1 in their panel top 16 adjacent area at a deviating from 90 ° angle ⁇ , namely with a smaller angle ⁇ , running to the panel top 16.
- this angle ⁇ is about 87 °.
- a flat recess 18 is mounted, which forms a glue pocket. If necessary, this glue pocket formed by the recess 18 serves to receive glue, provided that the laying of the panels 1, 2 is not glueless. Due to the design of the tongue and groove connection in the panels 1, 2 both a glueless laying and a laying under the indication of glue is possible. If glue is to be used in the laying, this is applied before the attachment of the second panel 2 in the corner region between the flat recess 18 and the top of the upper spring 11.
- the glue is concentrated in the glue pocket formed by the flat recess 18 in connection with the end face 20 of the second panel 2. There is enough space to pick up the glue without causing glue to stick to the top of the panel 16, 26 is coming. Dirt on the tops 16, 26 of the panels 1, 2 and the laying tools used in their installation are avoided. At the same time, the glue between the two panels 1, 2 ensures a secure seal and permanent mechanical connection.
- the figure 1 illustrates that here the panels 1, 2 have a relatively large thickness; this is especially true when it comes to the panels 1, 2 to finished parquet.
- the panels 1, 2 multi-layered, here constructed in three layers. At least the upper layer of the two panels 1, 2 preferably consists of a real wood layer, which is of such a thickness that, if necessary, a grinding and re-sealing a parquet floor formed from the panels 1, 2 after a certain period of use and a certain wear is possible ,
- FIG. 1 shows FIG. 1 by dashed lines that the depths of the grooves 21, 22 and the depth of the gap 13 can be varied.
- the flexibility of the web 23 and the springs 11, 12 is varied in desired areas, thereby affecting the ductility of the compound as a whole can be without the material from which the panels 1, 2 are made, must be changed.
- FIG. 2 the drawing shows in the same representation as the FIG. 1 also two interconnected panels 1, 2, which are panels 1, 2 of a laminate floor here.
- a laminate floor should have the lowest possible overall thickness, in order to allow a subsequent installation, without too large a material application occurs on an existing floor.
- connection of the two panels 1, 2 according to FIG. 2 has the left panel 1 at its right-facing side edge 10 a double spring of two springs 11, 12, which are separated by a gap 13 from each other.
- edge 20 of the second panel 2 has a double groove with two grooves 21, 22, between which a web 23 stands.
- the joining together of the panels 1, 2 to be joined is done simply by moving in the panel plane against each other until the springs 11, 12 engage in the grooves 21, 22 and the locking by means of the locking contour 14, 24 engages.
- the respective panel to be removed here the panel 2 is raised at its free, not visible in the drawing figure edge, resulting in a pivoting relative to the panel 1 about an axis results, which runs along the parting plane between the two panels 1, 2 at the level of the panel tops 16, 26.
- the equipped with the tongue and groove connection described panels 1, 2 thus offer in the connected state, even with glueless laying an excellent cohesion, At the same time, the possibility of a subsequent separation as required is maintained without damage. If required, finally, laying with glue addition is possible, whereby an absolutely solid connection is achieved, which is subsequently no longer schadlos solvable.
- the panels 1, 2 As a material for the panels 1, 2 known materials, such as HDF (high density fiberboard), but also all other plate materials made of wood or plastic, which can be processed with profiling tools, are used. With sufficiently strong materials, the total thickness of the panels 1, 2 may be less than 10 mm, which is particularly advantageous for laminate floors, so that despite the use of a double groove 21, 22 and double spring 11, 12 for the connection of the panels 1, 2 no additional Material thickness is required.
- the connection described above can be used regardless of the intended use of the panels 1, 2, so both in floor panels as well as wall or ceiling panels.
Abstract
Description
Die vorliegende Erfindung betrifft ein Paneel, insbesondere Fußbodenpaneel, wie Laminatboden; Fertigparkett; Furnierboden-oder Korkpaneel, mit einer Nut-Feder-Verbindung gemäß dem Oberbegriff des Anspruches 1. Die im Oberbegriff des Anspruchs 1 enthaltenen Merkmale sind aus der

Als nachteilig ist bei dieser Nut-Feder-Verbindung für Paneele anzusehen, daß bei vertikaler Wechselbelastung der miteinander verbundenen Paneele besonders große in Trennrichtung wirkende resultierende Kräfte zu erwarten sind, weil der keilförmige Vorsprung aufgrund seiner schrägen, mit den Enden der beiden Federteile in einem nur linienförmigen Kontakt stehenden Flächen zwangsläufig resultierende Kräfte hervorruft, die in Trennrichtung der beiden Paneele wirken. Ein weiterer Nachteil bei diesem bekannten Paneel besteht darin, daß ein späteres schadloses Trennen von zwei leimlos miteinander verbundenen Paneelen sehr schwierig oder sogar unmöglich ist. Ein schadloses Trennen wäre hier höchstens durch ein horizontales Auseinanderziehen der verbundenen Paneele möglich, was aber nur eine theoretische, praktisch nicht zur Verfügung stehende Möglichkeit ist, weil die erforderlichen Zugkräfte nicht schadlos auf die Paneele übertragbar sind. Bei einem Verkippen der beiden Paneele gegeneinander zur Trennung der Paneele käme es zwangsläufig zu einer Beschädigung zumindest des unteren Federteils, wenn nicht beider Federteile, so daß nach der Trennung die Paneele nicht mehr in der gewünschten Weise ein zweites Mal miteinander verbunden werden könnten.Is to be regarded as disadvantageous in this tongue and groove connection for panels that at vertical alternating load of the interconnected panels particularly large acting in the direction of separation resulting forces are to be expected, because the wedge-shaped projection due to its oblique, with the ends of the two spring parts in a only linear contact surfaces inevitably causes resulting forces acting in the separation direction of the two panels. Another disadvantage of this known panel is that a subsequent damage-free separation of two gluelessly interconnected panels is very difficult or even impossible. A harmless separation would be possible here at most by a horizontal pulling apart of the connected panels, but this is only a theoretical, virtually unavailable possibility, because the required tensile forces are not transferable to the panels without damage. In a tilting of the two panels against each other for the separation of the panels, it would inevitably damage at least the lower spring member, if not both spring parts, so that after the separation of the panels could not be connected in the desired manner a second time.

Für die vorliegende Erfindung stellt sich deshalb die Aufgabe, ein Paneel der ein-gangs genannten Art zu schaffen, das die dargelegten Nachteile vermeidet und mit dem insbesondere eine zuverlässige und stabile Verbindung zweier benachbarter Paneele möglich ist, wobei ein Höhenversatz zwischen den verbundenen Paneelen ausgeschlossen sein soll. Dabei soll einem Auseinanderbewegen der Paneele bei Nutzungsbelastung eine hohe Widerstandskraft entgegengesetzt werden, gleichzeitig aber bei Bedarf ein leichtes und schadloses Trennen der Paneele möglich bleiben. Zugleich soll das Verlegen und Verbinden der Paneele miteinander problemlos und einfach sein.For the present invention, therefore, the object is to provide a panel of the initially mentioned type, which avoids the disadvantages set out and with the particular reliable and stable Connection of two adjacent panels is possible, with a height offset between the connected panels should be excluded. In this case, a dislocation of the panels at use load high resistance to be opposed, but at the same time if necessary, a slight and harmless separation of the panels remain possible. At the same time laying and connecting the panels together should be easy and simple.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit einem Paneel mit einer Nut-Feder-Verbindung der eingangs genannten Art, das dadurch gekennzeichnet ist,
- dass die Nut durch eine Doppelnut mit zwei parallelen, durch einen federförmigen Steg getrennten Nuten ausgeführt ist, wobei der Steg je eine flache, parallel zueinander und zur Ober- und Unterseite des Paneels verlaufende Ober- und Unterseite aufweist, mit denen er im verbundenen Zustand zweier Paneele zumindest über einen Teil seiner Höhe in dem Zwischenraum liegt,
- dass die Höhen der Federn und des Steges und die Tiefen der Nuten und des Zwischenraumes so bemessen sind, dass im verbundenen Zustand der Paneele parallel zur Paneelober- und -unterseite verlaufende, flächige gegenseitige Anlagebereiche zwischen den einander benachbarten Oberflächen von Federn, Nuten, Steg und Zwischenraum bestehen, und
- dass die Rastkontur an der der Paneeloberseite zugewandten Seite der oberen Nut und oberen Feder vorgesehen ist.
- that the groove is formed by a double groove with two parallel, separated by a spring-shaped web grooves, the web each having a flat, parallel to each other and to the top and bottom of the panel extending top and bottom, with which he in the connected state of two Panels lie at least over part of its height in the space,
- that the heights of the springs and the web and the depths of the grooves and the gap are dimensioned such that in the connected state of the panels parallel to the Paneelober- and -unterseite extending, flat mutual abutment areas between the adjacent surfaces of springs, grooves, web and Intermediate space, and
- the catch contour is provided on the side of the upper groove and upper spring facing the panel top side.
Durch die Verwendung einer Doppelnut mit zwei Nuten und einer Doppelfeder mit zwei Federn wird erreicht, dass ein Höhenversatz von miteinander verbundenen Paneelen praktisch ausgeschlossen ist. Aufgrund der vergrößerten, im verbundenen Zustand der Paneele aneinander anliegenden Flächen im Verbindungsbereich wird zudem eine erhöhte Widerstandsfähigkeit gegen ein Auseinanderbewegen der verbundenen Paneele erreicht. Eine besondere Beschädigungsgefahr besteht bei dieser Verbindung nicht, da relativ dünne und lange Überstände im Bereich der Verbindung vermieden werden. Damit ist keine Anwendung einer besonderen Vorsicht oder einer besonderen Verpackung bei Lagerung, Transport und sonstiger Handhabung der Paneele erforderlich. Dies trägt dazu bei, daß die Paneele schnell und problemlos transportiert und verlegt werden können. Die Rastkontur zur formschlüssigen Arretierung zweier verbundener Paneele ist dabei so nah wie möglich an der Paneeloberfläche angeordnet, wodurch der Zusammenhalt der Paneele dort besonders gut wird. Damit liegt die Rastkontur in dem in der Regel stabileren oberen Bereich der Paneele, so daß eine hohe Widerstandsfähigkeit gegen ein Auseinanderziehen von verbundenen Paneelen erreicht wird. Außerdem ist bei dieser Anordnung der Rastkontur das Zusammenfügen zweier Paneele bei deren Verlegung vorteilhaft dadurch möglich, daß ein neu anzusetzendes Paneel einfach in der Ebene der schon verlegten Paneele an das zuletzt verlegte Paneel herangeführt und dann bis zu seiner endgültigen Anlage an das schon verlegte Paneel gebracht wird. Für den letzten Teil des Anlegens des neu verlegten Paneels an das schon verlegte Paneel können beispielsweise an sich bekannte Spann- oder Andrückwerkzeuge, wie Spanngurte oder Schlagklotz und Hammer, eingesetzt werden. Aufgrund ihrer Gestaltung ist die Nut-Feder-Verbindung sehr gut für eine leimlose Verlegung von Paneelen geeignet. Bei Bedarf, insbesondere zur Sicherstellung einer absoluten Feuchtigkeitsdichtigkeit im Bereich der Verbindung, kann auch eine Angabe von Leim im Bereich der Verbindung erfolgen. Neben der Abdichtung gegen einen Eintritt von Feuchtigkeit ist so selbstverständlich auch eine mechanisch absolut feste Verbindung gewährleistet. Bei schmalen Paneelen reicht es, wenn die Verbindung an den Längskanten der Paneele vorgesehen ist. Bei breiteren Paneelen ist zweckmäßig die Verbindung auch an den Stirnkanten vorgesehen. Bei diesen Paneelen kann vorteilhaft zunächst das Zusammenfügen zweier Paneele entlang der Längskanten erfolgen. Danach ist das zuletzt angesetzte Paneel noch in seiner Längsrichtung verschiebbar, sodaß es einfach durch eine solche Längsverschiebung dann auch an seiner Stirnkante in Eingriff mit dem stirnseitig benachbarten, vorher verlegten Paneel bringbar ist.By using a double groove with two grooves and a double spring with two springs is achieved that a vertical offset of interconnected panels is practically impossible. Due to the enlarged, in the connected state of the panels abutting surfaces in the connection area also an increased resistance to a moving apart of the connected panels is achieved. A special risk of damage does not exist in this connection, since relatively thin and long projections in the region of the connection can be avoided. This does not require the use of special care or packaging for storage, transport and other handling of the panels. This contributes to the fact that the panels can be transported and laid quickly and easily. The locking contour for the positive locking of two connected panels is arranged as close as possible to the panel surface, whereby the cohesion of the panels there is particularly good. Thus, the locking contour is in the usually more stable upper portion of the panels, so that a high resistance to pulling apart of connected panels is achieved. In addition, in this arrangement, the locking contour, the joining of two panels in their laying advantageous in that a newly attached panel simply brought in the plane of the already laid panels to the last laid panel and then brought to its final investment in the already laid panel becomes. For the last part of applying the newly installed panel to the already laid panel, for example, known per se clamping or pressing tools, such as straps or block and hammer hammer can be used. Due to its design, the tongue and groove connection is very well suited for glueless laying of panels. If necessary, in particular to ensure an absolute moisture-tightness in the region of the connection, an indication of glue in the region of the connection can also be made. In addition to sealing against entry of moisture is so natural also ensures a mechanically absolutely solid connection. With narrow panels, it is sufficient if the connection is provided on the longitudinal edges of the panels. For wider panels the connection is expediently also provided on the front edges. In these panels, the joining of two panels along the longitudinal edges can advantageously take place first. Thereafter, the last scheduled panel is still displaceable in its longitudinal direction, so that it can be brought easily by such a longitudinal displacement then at its front edge in engagement with the frontally adjacent, previously laid panel.
Um sicherzustellen, daß die verbundenen Paneele an ihrer Oberseite dicht aneinander anliegen, ist weiter vorgesehen, daß die Ebene der Paneelstirnfläche, von der die Nuten oder die Federn ausgehen, zumindest in ihrem der Paneeloberseite benachbarten Teil unter einem Winkel a von weniger als 90° zur Oberseite des Paneels verläuft und daß die Paneele in ihrem verbundenen Zustand unterhalb ihrer Oberseite in Verbindungsrichtung betrachtet einen Abstand voneinander aufweisen. Hiermit wird eine spaltfreie Verlegung der Paneele erleichtert, so daß auch die Gefahr eines Einsickerns von Feuchtigkeit in die Verbindungsbereiche vermieden wird. Dabei bleibt die dichte Verlegung auch erhalten, wenn innerhalb z.B. eines Fußbodens leichte Neigungswechsel vorliegen, sofern diese nicht größer sind als die Differenz zwischen dem Winkel a und 90°.To ensure that the joined panels abut each other at their top, it is further contemplated that the plane of the panel end surface from which the grooves or springs extend, at least in their panel upper side adjacent part at an angle a of less than 90 ° Top of the panel extends and that the panels in their connected state below their upper side viewed in the connecting direction at a distance from each other. Hereby, a gap-free installation of the panels is facilitated, so that the risk of moisture seeping into the connection areas is avoided. At the same time, the dense laying also remains if, within e.g. of a floor slight inclination changes are present, if these are not larger than the difference between the angle a and 90 °.
Bevorzugt beträgt der Winkel a zwischen 86 und 88°, besonders bevorzugt etwa 87°. Dieser relativ wenig vom rechten Winkel abweichende Winkel a reicht zur Erzielung der vorstehend erläuterten Spaltfreiheit bei den verlegten Paneelen aus, wobei gleichzeitig die gewünschte Anpassungsfähigkeit an Wölbungen des Untergrundes erhalten bleibt.Preferably, the angle a is between 86 and 88 °, more preferably about 87 °. This relatively little deviating from the right angle angle a is sufficient to achieve the previously described gap freedom in the laid panels, at the same time the desired adaptability is retained on vaults of the ground.
Weiter ist vorgesehen, daß die Tiefe des Zwischenraumes zwischen den Federn maximal bis zur Ebene der Paneelkante des zugehörigen Paneels reicht. Der Zwischenraum ist aufgrund dieser begrenzten Tiefe relativ einfach herstellbar; eine größere Tiefe des Zwischenraumes als hier angegeben ist nicht erforderlich, da eine Vergrößerung der Tiefe keinen Einfluß auf die Flexibilität der Federn mehr hat.It is further provided that the depth of the gap between the springs reaches at most to the level of the panel edge of the associated panel. The gap is relatively easy to produce due to this limited depth; a greater depth of the gap than specified here is not required, since increasing the depth has no effect on the flexibility of the springs more.
In weiterer Ausgestaltung ist vorgesehen, daß im verbundenen Zustand der Paneele der Steg zwischen 30 und 95 % der Tiefe des Zwischenraumes ausfüllt. Die Festlegung des Prozentsatzes richtet sich nach den Anforderungen an die Verbindung, wobei eine geringere Ausfüllung das spätere Trennen von Paneelen durch Verkanten gegeneinander erleichtert, während auf der anderen Seite ein größerer Grad der Ausfüllung für eine höhere Belastbarkeit der Verbindung bei Nutzung z.B. des Fußbodens aus diesen Paneelen bietet.In a further embodiment, it is provided that in the connected state of the panels, the web fills between 30 and 95% of the depth of the intermediate space. The determination of the percentage depends on the requirements of the connection, wherein a lower filling facilitates the subsequent separation of panels by tilting against each other, while on the other hand a greater degree of filling for a higher load capacity of the connection when using e.g. of the floor offers from these panels.
Zur Erleichterung des Einführens des Steges in den Zwischenraum beim Verlegen der Paneele ist der Steg vorzugsweise an seinem freien Ende mit gerundeten oder gefasten Kanten ausgeführt.To facilitate the insertion of the web into the gap when laying the panels of the web is preferably carried out at its free end with rounded or beveled edges.
Bei der Verlegung von Paneelen unter Anwendung von Leim kommt es häufig vor, daß überschüssiger Leim im Bereich der Verbindung nach oben hervorquillt und die Paneeloberseite sowie Verlegewerkzeuge verschmutzt. Um diese Verschmutzung und dadurch erforderliche Reinigungsarbeiten zu vermeiden, wird vorgeschlagen, daß in der Paneelstirnfläche, von der die Nuten oder die Federn ausgehen, im Abstand von der Paneeloberseite und oberhalb der oberen Nut oder oberen Feder eine flache Ausnehmung zur Bildung einer Leimtasche vorgesehen ist. Diese Leimtasche nimmt eventuelle Überschüsse des angegebenen Leims auf, sodaß dieser nicht nach oben hin austreten kann.When laying panels using glue, it often happens that excess glue in the area of the connection will bulge upwards and contaminate the panel top and laying tools. In order to avoid this pollution and thereby required cleaning work, it is proposed that in the panel end face from which the grooves or springs emanate in the Distance from the panel top and above the upper groove or upper spring a shallow recess is provided to form a glue pocket. This glue bag takes on any surpluses of the specified glue, so that it can not escape upwards.
Insbesondere zwecks einfacher Herstellbarkeit der Rastkontur ist bevorzugt vorgesehen, daß diese durch eine im Querschnitt dreieckige Erhebung auf der Oberseite der oberen Feder einerseits und durch eine gegengleiche Eintiefung in der Oberseite der zugehörigen, oberen Nut andererseits gebildet ist. Damit ist die Bearbeitung der Paneele im Bereich ihrer der Verbindung mit weiteren Paneelen dienenden Stirnkanten durch relativ einfache Fräswerkzeuge in einem stetigen Bearbeitungsdurchlauf möglich.In particular, for ease of manufacture of the locking contour is preferably provided that this is formed by a triangular in cross section survey on the top of the upper spring on the one hand and by a gegengleiche recess in the top of the associated upper groove on the other. Thus, the processing of the panels in the area of their connection with other panels serving end edges by relatively simple milling tools in a continuous processing cycle is possible.
Um einerseits das Zusammenfügen der Paneele noch mit einem unschädlichen Kraftaufwand zu ermöglichen und um andererseits eine möglichst große Widerstandsfähigkeit gegen ein Auseinanderziehen zu gewährleisten, ist vorgesehen, daß der Spitzenwinkel der Erhebung und der Eintiefung zwischen 90 und 120°, vorzugsweise etwa 105°, beträgt.On the one hand to allow the joining of the panels still with a harmless force and on the other hand to ensure the greatest possible resistance to pulling apart, it is provided that the apex angle of the survey and the recess between 90 and 120 °, preferably about 105 °.
In einer ersten Ausgestaltung der Rastkontur ist vorgesehen, daß die Erhebung mit zueinander symmetrischen Flanken ausgebildet ist. Bei dieser Ausführung ist die für das Zusammenfügen der Paneele erforderliche Kraft im wesentlichen so groß wie die Kraft, die zu einem Auseinanderziehen der Paneele erforderlich ist.In a first embodiment of the latching contour is provided that the survey is formed with mutually symmetrical flanks. In this embodiment, the force required to join the panels is substantially as great as the force required to pull the panels apart.
Eine alternative diesbezüglich Ausgestaltung sieht vor, daß die Erhebung mit zueinander unsymmetrischen Flanken ausgebildet ist, wobei die Flanke, die der die Feder tragenden Paneelkante zugewandt ist, flacher ist als die andere Flanke der Erhebung. Diese Ausgestaltung sorgt dafür, daß für das Zusammenfügen der Paneele eine kleinere Kraft ausreicht als die Kraft, die für ein Auseinanderziehen zweier Paneele aufzubringen ist.An alternative in this regard embodiment provides that the survey is formed with mutually asymmetrical edges, the flank, which carries the spring Panel edge is facing, is flatter than the other flank of the survey. This design ensures that a smaller force is sufficient for the joining of the panels as the force that is applied for pulling apart two panels.
Weiter schlägt die Erfindung vor, daß die obere Feder von der Paneeloberseite einen Abstand aufweist, der größer ist als der Abstand der unteren Feder von der Paneelunterseite. Diese unterschiedliche Beabstandung erleichtert ein späteres bedarfsweises Trennen zweier Paneele durch Verkanten gegeneinander, weil durch den größeren Abstand der oberen Feder von der Paneeloberseite hier schon ein relativ großer Radius von der in der Fläche der Paneeloberseite liegenden Schwenkachse bis zur oberen Feder vorliegt. Je größer dieser Schwenkradius ist, desto weniger wird die Feder bei dem Verkanten der Paneele zwecks deren Trennung beansprucht, so daß entsprechend auch die Beschädigungsgefahr für die Feder kleiner wird.Further, the invention proposes that the upper spring from the panel top has a distance which is greater than the distance of the lower spring from the panel underside. This different spacing facilitates a later need-based separation of two panels by tilting against each other, because by the larger distance of the upper spring of the panel top here is already a relatively large radius of the lying in the surface of the panel top pivot axis to the upper spring. The larger this pivot radius, the less the spring is claimed in the tilting of the panels for the purpose of their separation, so that accordingly the risk of damage to the spring is smaller.
Um das oben erwähnte Verlegen der Paneele zu erleichtern und um Schäden an den Federn während des Verlegevorgangges zu vermeiden, ist zweckmäßig das freie Ende der mit der Rastkontur ausgestatteten Feder oder das freie Ende beider Federn von deren Unterseite ausgehend mit einer kufenförmigen Abrundung ausgeführt.In order to facilitate the above-mentioned laying of the panels and to avoid damage to the springs during the laying process, the free end of the spring equipped with the locking contour or the free end of both springs is expedient starting from the bottom with a runner-shaped rounded.
Aus dem gleichen Grund wird vorgeschlagen, daß das freie Ende der ohne Rastkontur ausgeführten Feder gefast oder abgerundet ist. Hierdurch wird das Zusammenfügen der Paneele aufgrund des erreichten selbsttätigen Zentriereffekts erleichtert und es werden Schäden, insbesondere Absplitterungen, an der Feder vermieden.For the same reason, it is proposed that the free end of the executed without locking contour spring is chamfered or rounded. As a result, the joining of the panels is facilitated due to the achieved self-centering effect and there are damage, especially chipping, avoided on the spring.
Schließlich schlägt die Erfindung noch vor, daß die Fügigkeit der Verbindung zwischen den Paneelen durch Variation der Tiefe der Nuten und/oder des Zwischenraums veränderbar ist. Dies bietet den Vorteil, daß die Fügigkeit der Verbindung auch nachträglich noch beim Hersteller der Paneele beeinflußt werden kann, da üblicherweise die Paneele zunächst ohne Nuten und Federn mit glatten Kanten produziert werden. Die Nuten und Federn werden dann erst in entsprechenden Bearbeitungsstraßen nachträglich angebracht. Da die Materialeigenschaften der Paneele an sich nach deren Herstellung nicht mehr veränderbar sind, kann durch Veränderung der erwähnten Tiefen die Fügigkeit der Verbindung ohne Veränderung der Materialeigenschaften der Paneele noch in gewünschter Weise beeinflußt werden, um einerseits die Paneele möglichst leichtgängig miteinander verbinden zu können und um andererseits den Paneelen einen ausreichend festen Zusammenhalt auch bei leimloser Verlegung zu geben.Finally, the invention also proposes that the flexibility of the connection between the panels by varying the depth of the grooves and / or the gap is variable. This offers the advantage that the ductility of the compound can also be subsequently influenced even with the manufacturer of the panels, since usually the panels are initially produced without grooves and feathers with smooth edges. The grooves and springs are then attached later in appropriate processing lines. Since the material properties of the panels per se after their production are no longer changeable, the ductility of the compound without changing the material properties of the panels can still be influenced in a desired manner by changing the depths mentioned, on the one hand to connect the panels as easily as possible to each other and order On the other hand, to give the panels a sufficiently strong cohesion even when glued laying.
Zwei Ausführungsbeispiele der Erfindung werden im folgenden anhand einer Zeichnung erläutert. Die Figuren der Zeichnung zeigen:
Figur 1- zwei miteinander mittels einer Nut-Feder-Verbindung verbundene Paneele eines Parketts in einem Teil-Querschnitt durch den Verbindungsbereich und
- Figur 2
- zwei verbundene Paneele eines Laminatbodens, in gleicher
Darstellungsweise wie Figur 1 .
- FIG. 1
- two mutually connected by means of a tongue and groove connection panels of a parquet in a partial cross-section through the connecting portion and
- FIG. 2
- two connected panels of a laminate floor, in the same way as
FIG. 1 ,
Die
Die Nut-Feder-Verbindung besteht hier aus einer Doppelnut mit zwei Nuten 21, 22 im rechten Paneel 2 und einer Doppelfeder mit zwei Federn 11, 12 am linken Paneel 1. Die Federn 11, 12 ragen von der dem Paneel 2 zugewandten Stirnfläche 10 des ersten Paneels 1 vor. Entsprechend liegen die zugehörigen Nuten 21, 22 in der dem ersten Paneel 1 zugewandten Stirnfläche 20 des zweiten Paneels 2.The tongue and groove connection here consists of a double groove with two
Zwischen den beiden Federn 11, 12 liegt ein Zwischenraum 13. Zwischen den beiden Nuten 21, 22 steht ein Steg 23, der in den Zwischenraum 13 ragt. Die Höhe des Steges 23 ist aber kleiner als die Tiefe des Zwischenraums 13, so daß der Zwischenraum 13 bei dem gezeigten Beispiel nur etwa zur Hälfte von dem Steg 23 ausgefüllt wird, wenn die Paneele 1, 2, wie hier gezeigt, miteinander verbunden sind.Between the two
Weiter umfaßt die Nut-Feder-Verbindung eine formschlüssige Arretierung, die durch eine Rastkontur gebildet ist. Die Rastkontur besteht hier aus einer Erhebung 14, die an der oberen Flachseite der oberen Feder 11 vorgesehen ist, und einer gegengleichen Eintiefung 24, die oberseitig in der oberen Nut 21 angebracht ist. Die Erhebung 14 und die Eintiefung 24 sind im Querschnitt gesehen dreieckförmig, wobei der Spitzenwinkel β hier etwa 105° beträgt.Further, the tongue and groove connection comprises a positive locking, which is formed by a latching contour. The locking contour here consists of a
Das freie Ende der Federn 11, 12 ist, ausgehend jeweils von deren Unterseite, mit einer kufenförmigen Abrundung 15 ausgeführt, die das Zusammenfügen der Paneele 1, 2 und insbesondere auch ein bedarfsweises späteres Trennen der Paneele 1, 2 erleichtert.The free end of the
Zur Erleichterung des Zusammenfügens der Paneele 1, 2 trägt ebenfalls bei, daß bei dem hier gezeigten Ausführungsbeispiel das freie Ende des Steges 23 an seinen Kanten leicht gerundet ist.To facilitate the joining of the
Damit die verlegten Paneele 1, 2 in ihrem miteinander verbundenen Zustand an ihrer Paneeloberseite 16, 26 eine einheitliche und spaltenfreie Fläche bilden, ist hier die Stirnfläche 10 des linken Paneels 1 in ihrem der Paneeloberseite 16 benachbarten Bereich unter einem von 90° abweichenden Winkel α, nämlich mit einem kleineren Winkel α, zur Paneeloberseite 16 ausgeführt. Im vorliegenden Beispiel beträgt dieser Winkel α etwa 87°.Thus, the laid
Schließlich ist bei dem in der Zeichnungsfigur 1 linken Paneel 1 im Abstand von der Paneeloberseite 16 und oberhalb der oberen Feder 11 eine flache Ausnehmung 18 angebracht, die eine Leimtasche bildet. Bei Bedarf dient diese durch die Ausnehmung 18 gebildete Leimtasche zur Aufnahme von Leim, sofern die Verlegung der Paneele 1, 2 nicht leimlos erfolgt. Aufgrund der Gestaltung der Nut-Feder-Verbindung bei den Paneelen 1, 2 ist sowohl eine leimlose Verlegung als auch eine Verlegung unter Angabe von Leim möglich. Wenn Leim bei der Verlegung eingesetzt werden soll, wird dieser vor dem Ansetzen des zweiten Paneels 2 in den Eckbereich zwischen der flachen Ausnehmung 18 und der Oberseite der oberen Feder 11 aufgetragen. Nach dem Ansetzen und Andrücken des zweiten Paneels 2 von rechts nach links in Richtung zum bereits verlegten ersten Paneel 1 wird der Leim in der durch die flache Ausnehmung 18 in Verbindung mit der Stirnseite 20 des zweiten Paneels 2 gebildeten Leimtasche konzentriert. Hier ist ausreichend Raum vorhanden, den Leim aufzunehmen, ohne daß es zu einem Hervorquellen von Leim zur Paneeloberseite 16, 26 kommt. Verschmutzungen der Oberseiten 16, 26 der Paneele 1, 2 und der bei deren Verlegung eingesetzten Verlegewerkzeuge werden so vermieden. Zugleich sorgt der Leim zwischen den beiden Paneelen 1, 2 für eine sichere Versiegelung und dauerhafte mechanische Verbindung.Finally, in the left in the drawing Figure 1
Nahe den Paneelunterseiten 17, 27 verbleibt zwischen den Stirnflächen 10, 20 der beiden Paneele 1, 2 ein gewisser Abstand, so daß stets eine dichte Anlage der beiden Paneele 1, 2 im Bereich unmittelbar nahe den Paneeloberseiten 16, 26 gewährleistet ist, auch wenn gewisse Krümmungen oder Wölbungen des Untergrundes vorliegen, denen der Paneelbelag folgt, ohne daß die dichte Anlage verloren geht.Near the panel undersides 17, 27 remains between the end faces 10, 20 of the two
Schließlich verdeutlicht die Zeichnungsfigur 1, daß hier die Paneele 1, 2 eine relativ große Dicke aufweisen; diese liegt insbesondere dann vor, wenn es sich bei den Paneelen 1, 2 um Fertigparkett handelt. In diesem Fall sind vorzugsweise, wie in der Zeichnung durch strichpunktierte Linien angedeutet, die Paneele 1, 2 mehrschichtig, hier dreischichtig aufgebaut. Zumindest die obere Lage der beiden Paneele 1, 2 besteht dabei vorzugsweise aus einer Echtholzschicht, die von einer solchen Dicke ist, daß bedarfsweise ein Abschleifen und erneutes Versiegeln eines aus den Paneelen 1, 2 gebildeten Parkettbodens nach einer gewissen Nutzungsdauer und einem gewissen Verschleiß möglich ist.Finally, the figure 1 illustrates that here the
Außerdem zeigt die
Auch bei der Verbindung der beiden Paneele 1, 2 gemäß
Auch bei dem Ausführungsbeispiel gemäß
Wie oben schon erwähnt, erfolgt das Zusammenfügen der miteinander zu verbindenden Paneele 1, 2 einfach durch Verschieben in der Paneelebene gegeneinander, bis die Federn 11, 12 in die Nuten 21, 22 eingreifen und die Verriegelung mittels der Rastkontur 14, 24 in Eingriff gelangt. Zum Trennen der Paneele 1, 2 ist bei beiden Ausführungsbeispielen vorgesehen, daß das jeweils zu entfernende Paneel, hier das Paneel 2, an seiner freien, in der Zeichnungsfigur jeweils nicht sichtbaren Kante angehoben wird, wodurch sich eine Verschwenkung relativ zum Paneel 1 um eine Achse ergibt, die entlang der Trennebene zwischen den beiden Paneelen 1, 2 in Höhe der Paneeloberseiten 16, 26 verläuft. Durch Verschwenkung um diese Achse lassen sich mit relativ geringem Kraftaufwand und insbesondere ohne die Gefahr einer Beschädigung der Federn 11, 12 und des Steges 23 die Paneele 1, 2 voneinander bei Bedarf trennen, wobei zu diesem Zweck selbstverständlich die Verbindung leimlos erfolgt sein muß. Zu dieser leichten Trennbarkeit der Paneele 1, 2 ohne Beschädigung der Federn 11, 12 trägt auch bei, daß die Federn 11, 12 an ihrem freien Ende jeweils von ihrer Unterseite ausgehend mit einer kufenförmigen Ausrundung 15 versehen sind.As already mentioned above, the joining together of the
Gleichzeitig verdeutlichen die beiden Zeichnungsfiguren 1 und 2, daß bei einer Wechselbelastung in einer Richtung senkrecht zur Ebene der Paneele 1, 2 die Kräfte jeweils rechtwinklig durch parallel zu den Oberseiten 16, 26 und Unterseiten 17, 27 der Paneele 1, 2 verlaufenden Kontaktflächen von oben nach unten weitergeleitet werden. Resultierende Kräfte, die in Richtung einer Trennung der Paneele 1, 2 voneinander wirken, treten deshalb hier aus Prinzip nicht auf; vielmehr wird sogar die Verbindung dadurch verstärkt, daß die Flanke 14' im Zusammenwirken mit der entsprechenden Schrägfläche der Ausnehmung 24 die Paneele 1, 2 in Richtung zueinander drückt, wenn eine vertikale Belastung auftritt.At the same time clarify the two drawing figures 1 and 2, that at an alternating load in a direction perpendicular to the plane of the
Die mit der beschriebenen Nut-Feder-Verbindung ausgestatteten Paneele 1, 2 bieten also im verbundenen Zustand auch bei leimloser Verlegung einen hervorragenden Zusammenhalt, wobei zugleich die Möglichkeit einer bedarfsweisen nachträglichen Trennung ohne Schäden erhalten bleibt. Bei Bedarf ist schließlich auch eine Verlegung mit Leimzugabe möglich, wodurch eine absolut feste Verbindung erzielt wird, die nachträglich allerdings nicht mehr schadlos lösbar ist.The equipped with the tongue and groove connection described
Als Material für die Paneele 1, 2 können bekannte Werkstoffe, beispielsweise HDF (high density fiberboard), aber auch alle anderen Plattenmaterialien aus Holz oder Kunststoff, die mit Profilierungswerkzeugen bearbeitbar sind, eingesetzt werden. Bei ausreichend festen Werkstoffen kann die Gesamtdicke der Paneele 1, 2 weniger als 10 mm betragen, was insbesondere für Laminatböden vorteilhaft ist, so daß trotz der Verwendung einer Doppelnut 21, 22 und Doppelfeder 11, 12 für die Verbindung der Paneele 1, 2 keine zusätzliche Materialstärke erforderlich ist. Die vorstehend beschriebene Verbindung kann unabhängig vom Verwendungszweck der Paneele 1, 2 eingesetzt werden, also sowohl bei Fußbodenpaneelen als auch bei Wand- oder Deckenpaneelen.As a material for the
