Description

  • The The invention relates to a panel for forming a coating, in particular Flooring, with other similar panels, with a carrier plate and one in one piece formed with the support plate first side edge and second side edge, wherein the first side edge and the second side edge on opposite sides of the carrier plate arranged and formed corresponding to each other, around with first and second side edges of similar panels in a direction substantially perpendicular to the carrier plate on the one hand and in a direction substantially parallel to the carrier plate and locked perpendicularly to the joined side edges, on the other hand to be, with the first side edge and the second side edge are formed to be with first and second side edges similar panels by a substantially perpendicular to the support plate extending movement to be connected, the first side edge a locking lip and the second side edge a locking nose, wherein the locking lip and the locking lug are formed so as to be with each other connected side edges a supernatant in one direction parallel to the panel and perpendicular to the connected side edges to build.
  • panels This type are already in different versions known practice. Corresponding panels become common used to form a floor, ceiling or wall covering. The individual panels can be opened by a mechanical lock at the circumferentially provided side edges with the side edges more similar Assemble panels to a suitable covering. The panels are doing at the side edges typically in two different Directions locked together. One of these directions runs in the plane of the panels and perpendicular to the interconnected Side edges. The other direction is perpendicular to each other aligned panels. Such panels can without the use of an adhesive to a flat surface get connected.
  • The Panels of the type mentioned have a carrier plate, which is usually made of a wood material. As a wood material In particular, medium-density fiberboard (MDF) or high-density fibreboard are used Fiber board (HDF) used. Alternatively, however, come chipboard or Oriented Strained Boards (OSB). On the top the backing plates is typically a decorative layer applied in the form of a laminate coating or paint. In this context, one speaks of laminate panels. At the opposite Bottom of the support plate can be a Gegenzugschicht and / or be provided a footfall sound insulation. Is the panel In contrast, made of solid wood and on the decorative layer has been omitted, it is called parquet panels, where the Top, d. H. the visible side, and if necessary, the bottom is formed by the carrier plate itself. In rarer ones Cases, the carrier plate is made of a plastic or formed from a plastic / wood-material mixture.
  • Since the panels are connected to each other at the first and second side edges by a movement more or less perpendicular to the panel, the known panels are also referred to as push-lock panels. In the case of floor panels, such panel types are characterized by the fact that the locking of two side edges by placing a side edge of a new panel from above on the adjacent, corresponding side edge of a resting on the ground panel and pushing down the new panel in the direction of the ground. In the manner described panels can be laid very easily and quickly together. Panels of this kind are from the EP 1 518 032 B1 known.
  • But panels can also have so-called snap-profiles for nesting two adjacent arranged in a plane panels in a direction perpendicular to the side edges to be joined. When joining such profiles, a groove element of a side edge is widened by a spring element of the adjacent side edge, so that the spring element can penetrate into the groove element. Then the groove member closes again and locked in this way with the spring element. Panels of this type are for example in the WO 97/47834 A1 described.
  • Out The same document also discloses a possible panel type. the so-called angle profiles for angleing adjacent side edges into each other. This is a panel angled and with a Spring element obliquely into a groove element of the adjacent Inserted panels. Then the angled panel goes down pivoted until the panels to be joined together in one common plane are arranged. In this final Position, the two panels are then locked together.
  • For panels with side edges, which are connected by the push-lock method with other corresponding side edges of similar panels and are integrally connected to the support plate, it can easily damage the panels during the connection of the corresponding side edges. This is special Therefore, the case because the support plate is made of a solid and rigid material and thus have the side edges formed of the same material have a low flexibility.
  • The Locking the side edges by a direction of movement in the Essentially perpendicular to the panel runs based on the formation of a locking connection between the side edges. When connecting Thus, parts of the side edges are deformed to the connected Condition of the side edges to lock them together.
  • by virtue of The reduced flexibility is the result of deformation However, the side edges to cracks or the like in the structure the carrier plates. This is especially true with panels a small thickness of the case. The locking profiles of the side edges must then be formed with very small dimensions, why the elasticity of the locking profiles continues is reduced.
  • at the use of fiberboard is added to the fact that the orientation of the fibers is not evenly distributed but the fibers are a preferential direction parallel to the panel take (anisotropy). Voltages perpendicular to this preferred direction therefore more likely to damage the Panels or carrier plates.
  • Around to address these disadvantages has already been proposed provide separate locking elements made of a material on the side edges, the greater elasticity than the carrier plate having. However, this has an increased production cost result. In addition, by using separate Locking elements the number of possible sources of error increased in the manufacture of the panels. Consequently, rising the danger that two panels of a flooring will not work as desired connect with each other. The use of separate locking elements will therefore considered only as a workaround.
  • In front In this background, the present invention is the technical Problem on, to propose a panel of the type mentioned, at when connecting the panel to other similar panels less common damage to each other locked side edges comes.
  • The previously indicated technical problem is at a panel of the beginning mentioned type with the features of the preamble of claim 1 thereby solved that the locking lip and / or the locking lug sectionally shortened along the side edge, so that the supernatant along the interconnected Side edges varies.
  • Under The supernatant is the area of a connection between a first side edge of a panel and a second side edge another similar panel understood in which the locking lip the first side edge opposite the locking nose the second side edge and vice versa. The locking lip and the locking lug stand in a direction parallel to the panels or to the support plate and perpendicular to the side edges is, against each other. This is with In other words, for example, always the case when the locking lip at least partially on the second side edge facing Side of a level is arranged through a front end of the Locking nose extends and extends perpendicular to the panel, and vice versa.
  • The lengthwise dimension of the supernatant in a direction perpendicular to the joined side edges and parallel to at least one panel, especially both together connected panels, is called the width of the supernatant designated. The lengthwise dimension in a direction along the interconnected side edges, is referred to as the length of the supernatant.
  • According to the invention provided that a first side edge and one with the first Side edge connected second side edge of adjacent panels not As usual, form a supernatant, the along the interconnected side edges one - to to manufacturing tolerances or the like unintentionally exist Fluctuations - has constant width. The supernatant rather varies in width along the one another connected side edges. This means that a section of the first side edge is provided, which has a shortened locking lip and thus be referred to as a shortened section can. Alternatively or additionally, at the second side edge a shortened section may be provided which is a shortened one Has locking nose.
  • A shortened section is determined less by the absolute width of the locking lip or the locking lug than by the fact that the locking lip and / or the locking lug in the shortened portion is relatively shorter than seen outside of the shortened portion. In other words, when the first and second side edges are connected in the shortened section, the locking lip and / or the locking projection projects less towards the adjacent side edge, in a direction parallel to the corresponding panel. The difference in the width of the supernatant between In the shortened section and an adjacent remaining section can be seen in absolute terms low. However, in terms of the width of the supernatant, especially in the shortened section, the width difference is by no means negligible, but in particular noteworthy.
  • ever greater the width of the supernatant between the Locking lip and the locking lug of two corresponding Side edges and possibly the more vertical the movement in relation to the Panel is connected to the two side edges higher loads are the first side edge and the second side edge, in particular the locking lip and the locking tab, when connecting the adjacent panels exposed. These loads are about as tensions on the panels on the one hand limited and on the other hand be suitably adjusted when the locking lip, the locking nose or both shortened in sections is / are.
  • By the extent of the shortening and the size of the section or its frequency along the corresponding Side edge can reduce the load to an acceptable level and yet a firm and lasting connection between the two Side edges are ensured. This leads, for example to better results and higher degrees of freedom than a shortening of the locking lip and / or the locking lug along the entire corresponding side edge, from which again a supernatant substantially constant width results. Preferably the shortened sections at the corresponding side edge where provided, without a shortening of the locking lip and / or locking lug particularly high stresses on the carrier plate occur would.
  • The Side edges, especially if the panels are made of a wood material or wood are formed by milling. Then done the sectionally shortening of the connecting lip and / or the connection nose preferably characterized in that in the region of at least a shortened section more material is removed than in a non-shortened section of the same side edge. It can in principle also different shortened sections may be provided. This means that the locking lip and / or the locking lug in a first shortened section shortened more is as in a second shortened section.
  • Also if this is not absolutely necessary, they are the same Panels preferably for joining in a certain relative Orientation provided with each other. This relative orientation is For example, then complied with, if the outer Ends of the first side edge and the second side edge in the one another Connected state are arranged in alignment with each other, so that also the panels are provided in alignment with each other. Then already clear before connecting first and second side edges, as the first side edge cooperates with the second side edge, in particular like the width of the protrusion between both side edges varies in the interconnected state along the side edges.
  • at a first embodiment of the panel are the first side edge and the second side edge is formed such that the locking lip and the locking nose interconnected first and second Side edges of adjacent panels engage behind. Wear it the locking lip and the locking lug for locking the two side edges to be joined together. A vote in terms of low stress when connecting the first and the second side edge and at the same time a solid and durable Lock between the side edges of adjacent panels then especially effective.
  • In In this context, it is preferred if the locking lip and the locking lug corresponding locking surfaces have, wherein the corresponding locking surfaces for locking the adjacent first and second side edges in FIG a direction perpendicular to the panel are formed. To this Purpose are the locking surfaces when connected first and second side edge to each other. A precise, local Restriction on connecting the first and the second Side edge occurring maximum stress by at least a truncated area can then ensure that Damage to the locking surfaces is prevented and lock the side edges together as desired.
  • alternative or additionally, it may be provided that the first side edge and the second side edge for producing a latching connection with latching the locking lip and the locking lug formed with each other are. Then it is particularly desirable that when locking the Locking lip with the locking nose adjacent first and second side edges occurring stresses by accordingly limit shortened sections.
  • For an effective local reduction of the loads occurring when connecting the panels, in a further embodiment of the panel, the locking lip and / or the locking nose are shortened in sections so that the Verrie gelungslippe a first side edge and the locking lug a second side edge in the interconnected state of the side edges in the shortened portion do not form a supernatant. In other words, the locking lip and the locking lug in the shortened portion in a direction perpendicular to the interconnected side edges and parallel to at least one of the two panels are not against each other and therefore do not come in contact with each other when connecting the two side edges. In the shortened section, in particular, a gap is formed between the locking lip and the adjacent locking nose in the case of the interconnected first and second side edges.
  • alternative or additionally, it may be provided that the locking lip immediately adjacent to an outer end of the first side edge and / or the locking lug immediately adjacent to an outer end of the second side edge is shortened. This is useful because in areas immediately adjacent to at least one outer End of the first and / or second side edge when connecting this Side edges local load peaks occur. By a correspondingly close to the edge shortened section of the first and / or the second side edge, if necessary, further such shortened sections, can be a precise local discharge of the first and / or second side edge can be achieved.
  • Around a particularly simple and rapid laying of a covering to allow for multiple panels without it The panel can damage the panels a third and a fourth corresponding to each other Side edge to the third and fourth side edges more similar to lock adjacent panels together. This locking is preferably done by the third Side edge of a panel in an angled position in the fourth side edge of another panel is inserted, whereupon then the angled panel in the same plane with the other panel is pivoted to the two adjacent Lock side edges together. One speaks in this context also from an angle about a third side edge in one fourth side edge of an adjacent panel or from an angle connection.
  • Then It is possible to connect a third side edge and a fourth side edge of similar adjacent panels, in particular by pivoting the panel and angling the third Side edge in a fourth side edge of the other similar Paneels, at the same time a first side edge and / or second side edge this panel with a corresponding first and / or second Side edge of an additional adjacent panel too connect. For locking the first and second side edges of a Pads of similar panels are then preferably not needed additional process steps when laying as the, anyway for locking the third and fourth side edges required are. The third and fourth side edge of a panel do not have to be with the first and the second side edge of the Panels correspond. Preferably, these are designed to that the third and fourth side edge of a panel not with the locked first and / or the second side edge of a similar panel can be.
  • Under a locking of first and second side edges of adjacent Panels in a direction substantially perpendicular to the panel will be so also understood locking movements, by pivoting a panel about an axis of rotation, preferably perpendicular to the first and / or second side is caused. The rotation axis is more preferably in a connection region of the other to be joined third and fourth side edges of adjacent panels. In the case of a floor covering is also under a locking direction, which is oriented substantially perpendicular to the panel, preferably Any direction understood by a panel by a movement the panel more or less from top to bottom with another Panel is connected.
  • Especially at a panel with a corresponding third and fourth side edge It makes sense that the locking lip of the first side edge and / or the locking lug of the second side edge directly is shortened adjacent to the third side edge. There kick namely in the described type of laying similar panels particularly high stresses on the carrier plate. moreover can then use a panel before joining the third side edge a fourth side edge of a front panel with its first and / or second side edge so close to an already laid Side panel can be arranged that the panel when leaning down simultaneously with the third side edge with the front panel and with the first or second side edge with the side panel can be locked without performing any further process steps to have to. In particular, it requires in the course of the downward angle no displacement of the panel in the direction of the first or second side edge to be joined, side panel.
  • In a further preferred embodiment of the panel, the locking lip and / or the locking lug is shortened at a plurality of spaced-apart sections. With others Words are provided along a first and / or second side edge a plurality of shortened portions. In this way, the loads occurring when connecting adjacent panels can be reduced more uniformly over the length of the side edges.
  • This can be achieved, for example, that the locking lip immediately adjacent to the outer ends of the first side edge and / or the locking lug immediately adjacent shortened to the outer ends of the second side edge is. This is particularly appropriate to the end areas when connecting relieve the adjacent side edges.
  • Around Discontinuities of the first side edge and / or the second side edge to avoid, which in turn can cause voltage spikes, it makes sense if the locking lip and / or the locking lug arcuately shortened along the side edge. Then the locking lip and / or the locking lug extends along the corresponding side edge in the form of a bow.
  • If As a result, the load peaks are not reduced in a suitable manner let it be convenient, the locking lip and / or the locking nose wavy along the first and / or shorten the second side edge. This will be a as steady transition from shortened Sections and not shortened sections along the corresponding side edge reached. It is preferred if a uniform waveform of the locking lip and / or the locking nose with wavelengths between 2 to 3 cm is chosen.
  • The through the at least one shortened section along the first and / or second side edge are advantages particularly pronounced when the panel at the first side edge of a from the top downwardly directed away feather key and a locking groove has, the second side edge one from the bottom to the top directed the locking lug having locking spring and has a fitting groove adjacent to the locking spring. In such a panel are in the connected state, the feather key with the fitting groove and the locking spring with the locking groove engaged.
  • there It leads to a particularly precise and durable Connection, when the distal end of the key at the groove bottom of Passnut rests.
  • The when connecting adjacent panels occurring loads can in addition to the at least one shortened Section also by a side facing away from the locking groove side the elasticity of the locking lip arranged elasticity groove reduced become. Due to the elasticity groove provided in the carrier plate the locking lip gets a higher elasticity, by the dimensions of the elasticity and thereby, if necessary can be adjusted, that the elasticity groove with a elastic material filled or filled is.
  • to Production of a panel for the formation of a covering, in particular Flooring, comes with other similar panels a method in which, from a carrier plate in each case in one piece on opposite sides a first side edge with a locking lip and a second one Side edge to be worked out with a locking nose, wherein the first side edge and the second side edge are such be worked out in a corresponding manner to one another by a Movement substantially perpendicular to the panel with first and second Side edges of similar panels in one direction substantially perpendicular to the panel on the one hand and in one direction substantially parallel to the panel and perpendicular to the side edges on the other to be locked, with the first side edge and the second Side edge worked out so corresponding to each other so that the locking lip and the locking lug interconnected first and second side edges in one direction perpendicular to the first and / or second side edge and parallel form a supernatant to the support plate and wherein the locking lip along the first side edge and / or the locking lug along the second side edge in sections shortened is worked out, so that the width of the supernatant varies along the interconnected first and second side edges.
  • Procedurally, thus become on opposite sides of a support plate integral with this carrier plate a first and a second side edge worked out, the corresponding are formed to each other. The first and the second side edge Correspond to each other in such a way that the first and the second side edge by a movement that is substantially vertical to the connected panels, with first and second Side edges of similar panels can be connected.
  • In this case, if necessary, any movement can be essentially perpendicular to the panel, the direction of which, in addition to a predominantly vertical component, also has a subordinate component parallel to the panel. In general, one could also speak of a movement that takes place from one side of the panel. The movement In any case, the panel for joining the same differs fundamentally from the movement for joining snap-profiles or angle-profiles. The design of the first and the second side edge of the panel namely corresponds in particular to a so-called push-lock profile.
  • in the connected state of a first and a second side edge adjacent similar panels are the first and the second side edge such locked together, that the panels are no longer readily available in a direction perpendicular to the panels, so by mutual Take off, can be separated. A seperation but the panels is also by a locking of the first side edge with the second side edge in a direction parallel to the panels and perpendicular to the connected side edges.
  • Essential is, however, that the first side edge and / or the second side edge not uniform along the corresponding side edge be worked out. It rather becomes conscious in sections the locking lip and / or the locking lug in one direction shortened parallel to the panel and perpendicular to the corresponding side edge worked out. This has the consequence that the locking lip and the locking lug in the connected state with other similar Panels along the interconnected side edges no form uniform supernatant. In that at least a shortened section in which the locking lip and / or the locking lug shortened from the carrier plate has been worked out, the supernatant is between the locking lip and the adjacent locking lug not as wide as in the at least one adjacent, remaining section. The difference in width is not just due to manufacturing tolerances or otherwise caused random fluctuations, but deliberately brought about by appropriate measures.
  • By the sections shortening of the locking lip and / or The locking lug can be used when connecting a panel occurring with other similar panels on the support plate acting loads are reduced. In addition, you can the occurring during the joining along the side edges Loads can be set in the desired manner, that a predetermined maximum value is nowhere along the first and / or second side edge is exceeded. Since the locking lip and / or the locking lug only partially shortened worked out of the carrier plate Nevertheless, a solid and permanent connection can be made between them the first side edge and the second side edge of each other be secured connected panels.
  • Also if this is not absolutely necessary, they are the same Panels preferably for joining in a certain relative Orientation provided with each other. This relative orientation is For example, then complied with, if the outer Ends of the first side edge and the second side edge in the one another Connected state are arranged in alignment with each other, so that also the two interconnected panels aligned with each other are aligned. It is then before connecting first and second side edges defined as the first side edge with the second side edge cooperates, in particular as the width of the supernatant between both side edges in the interconnected state varies along the side edges.
  • The Working out the first side edge and / or the second side edge on the one hand and / or the locking lip and / or the locking nose on the other hand, in a simple case, by at least one rotating Milling tool done. Alternatively or in addition but for the stated purpose at least one fixed one Broaching be provided. It is in principle also the Use of other known from the prior art tools conceivable but generally less preferred. To be favoured the carrier plates are guided past the at least one tool, instead of the at least one tool on the carrier plates pass, even if this is possible in principle is.
  • The Locking lip and the locking lug, for example from a carrier plate formed from a wood material milled. This can be done very precisely. In addition, corresponding locking lips and locking lugs tend in particular, damaged when locking each other to become. For these reasons, preferably both the first side edge and the second side edge of a such support plate milled out, wherein the Profile of the first side edge and the second side edge so formed are that this can be done easily. Especially good to perform the procedure when one of a medium density Fiberboard (MDF board) or a high-density fiberboard (HDF board) formed support plate is used. These carrier plates because of their structure when connecting adjacent panels particularly easily damaged.
  • Alternatively or additionally, it may be provided that the locking lip along the first side edge and / or the locking lug along the second side edge such a shortened work out in sections, so that in the thus formed ver shortened sections the locking lip and the locking lug form no projection. In other words, the locking lip, the locking lug or both elements is shortened in sections so that the locking lip and the locking lugs of interconnected side edges no longer in a direction parallel to the support plate and perpendicular to the interconnected side edges against each other, in the section, in the shortening lip and / or the locking lug has been shortened, ie in the shortened section. The locking lip and the locking nose then do not touch when connecting the side edges, so that there are no significant forces are introduced into the carrier plate when connecting.
  • The If necessary, shortening can go as far as piecemeal along the first side edge no locking lip and / or Sectionally no locking lug along the second side edge is worked out. There where no supernatant between the locking lip and the locking lug in the connected State adjacent panel can provide, if necessary, also completely dispensed with the locking lip and / or the locking lug become. Either the shortened section no locking lip and / or Locking nose worked out, or one already worked out Locking lip and / or locking lug later partially removed again.
  • There at least one outer ends of the first and / or the second side edge of conventional panels frequently particularly high loads occur when locking the panels, may be provided to relieve these areas, the locking lip and / or the locking lug immediately adjacent to at least an outer end of the first side edge and / or second side edge shortened to work out.
  • Especially In this context, it makes sense if the first side edge and the second side edge on short sides of the support plate worked out become. Then, on the long sides of the carrier plate or the panel, a third side edge and a fourth side edge are provided, which are provided for angling into one another (Angle profiles). While leaning down when cornering can simultaneously with a first and / or a second side edge similar panels are connected. To do this, the first side edge and the second side edge of adjacent panels however, be brought so close together that they swing down during the angle of the third side edge actually with each other can be locked. In order to make this possible, It may be appropriate, the locking lip on the first side edge and / or the locking lug on the second side edge immediately adjacent to the third side edge shortened work out of the carrier plate. Thus, it may be possible to prevent the locking lip and the Locking nose adjacent side edges already abut, before the first and second side edges are pushed together and thus are aligned when the angle of the panel to be connected to its third side edge.
  • The Shortening of the locking lip and / or the locking lug immediately adjacent to the third side edge may alternatively or in addition to relieving the panel in these otherwise possibly contribute to heavily loaded areas of the panel. If necessary, can, even if that is generally less preferred is the first and the second side edge at the longer Narrow edges of the carrier plate and the third and fourth Side edge at the shorter narrow edges of the carrier plate be provided.

For this purpose, the milling tool is preferably designed as an oscillating milling tool. In other words, procedurally, the locking lip along the first side edge and / or the locking lug along the second side edge by an oscillating milling tool both sections shortened as also sections are uncut out of the carrier plate.
  • It but can be for reasons of manufacturing accuracy or the production speed be appropriate for shortening the locking lip and / or the locking lug to use a separate oscillating milling tool. This is then used, only in sections, in particular in the shortened portion of the locking lip to be formed and / or the locking lug, material from the carrier plate to remove. This can be done either before the actual working out the locking lip and / or the locking lug from the carrier plate or subsequently. In the first case, material becomes the locking lip and / or the locking nose already before the actual working out of the locking lip and / or the locking nose removed while in the second case the locking lip and / or locking lug first essentially along the entire first and / or second side edge worked out of the carrier plate and then shortened by the oscillating milling tool becomes.
  • It So can in the former method alternative with a be provided separate oscillating tool along the locking lip the first side edge and / or the locking lug along the second side edge by a fixed milling tool to work out of the carrier plate and subsequently the locking lip and / or the locking lug by an oscillating To shorten the milling tool in sections.
  • at the second alternative method with a separate oscillating Tool is then but along the first side edge and / or along the second side edge by an oscillating Fräswerkzug in the field of subsequently from the carrier plate to be worked out locking lip and / or locking lug partially removed material of the carrier plate and in a subsequent process step, the locking lip along the first side edge and / or the locking lug along the second side edge by a fixed milling tool worked out of the carrier plate.
  • The Oscillating the respective oscillating milling tool is preferably at the clock rates for processing on the Milling tool guided by carrier plates Voted. In particular, the timing of the oscillating corresponds Milling tool with respect to a complete oscillating movement of the clocking of the oscillating milling tool guided by carrier plates. The oscillation the oscillating milling tool ultimately allows the carrier plates to be processed at high speed in a linear movement past the milling tool.
  • It is particularly easy when the oscillating milling tool moved along a circular path. Then the oscillating milling tool if necessary, only at certain points of the circular path with the support plate come into contact, in the sections where the locking lip and / or the locking lug should be shortened.
  • additionally or alternatively to the circular motion, the oscillating milling tool for partially shortening the locking lip and / or the locking lug also parallel and / or perpendicular to the support plate to be moved. This can be the desired Material removal at the locking lip and / or locking lug by a simple choice of the oscillating milling tool parallel to the carrier plate, perpendicular to the carrier plate and / or achieve circular movement.
  • The The present invention will now be described by way of example only illustrative drawing explained in more detail. In the Drawing shows
  • 1a two interconnected panels of a floor covering according to a first embodiment of the invention in a side view,
  • 1b the interconnected panels 1a in a view from below,
  • 2a two interconnected panels of a floor covering according to a second embodiment of the invention in a side view,

  • 4b the two interconnected Panels off 4a in a view from below and
  • 5 a possible method for the production of panels of a covering in a schematic representation.
  • In the 1a are two panels 1 . 2 shown in an interconnected state. This is the first panel 1 with its first side edge 3 with the second side edge 4 a second panel 2 connected, including the first side edge 3 and the second side edge 4 are formed corresponding to each other. Not shown in detail is that the first panel 1 and the second panel 2 on opposite narrow sides in each case a first side edge 3 and a second side edge 4 exhibit. In the illustrated and insofar preferred panels 1 . 2 are the first side edge 3 and the second side edge 4 on the short narrow edges of the panels 1 . 2 arranged.
  • The first side edge 3 of the first panel 1 and the second side edge 4 of the second panel 2 are engaged by a movement that is more or less perpendicular to the plane of the panels 1 . 2 runs. In the illustrated arrangement, the first panel 1 from the top to the second panel 2 attached.
  • The first side edge 3 has one of an upper side 5 downward directed feather key 6 and one in the direction of the second panel 2 extending locking lip 7 on. Between the locking lip 7 and the feather key 6 is a locking groove 8th intended. In the locking groove 8th engages in the connected state, a locking spring 9 the second side edge 4 one, extending from a bottom 10 of the second panel 2 extends upwards. At the same time is the feather key 6 engaged with one on a second panel 2 facing side of the locking spring 9 provided passport 11 , In the illustrated preferred embodiment, the distal end of the feather lies 6 at the groove bottom of the fitting groove 11 at. Further, the feather key 6 and the locking spring 9 adapted to the panels 1 . 2 in a direction perpendicular to the side edges 3 . 4 and parallel to the panels 1 . 2 are locked.
  • The locking lip 7 is at a lower end of the first side edge 3 provided and engages behind one of the locking spring 9 the second side edge 4 provided locking nose 12 , The locking lip 7 and the locking nose 12 have corresponding locking surfaces 13 . 13 ' on, in the illustrated, connected state of the two panels 1 . 2 abut each other and the side edges 3 . 4 thereby in a direction perpendicular to the adjacent panels 1 . 2 lock against each other. The side edges 3 . 4 are in one piece with the carrier plates 14 the first and the second panel 1 . 2 educated.
  • In a direction parallel to the panels 1 . 2 and perpendicular to the side edges 3 . 4 form the locking lip 7 and the locking nose 12 a supernatant 15 with a width b off. Like in the 1b is shown in a view from below, the width b of this supernatant varies 15 along the two interconnected side edges 3 . 4 , This is due to the fact that the locking lip 7 the first side edge 3 of the first panel 1 immediately adjacent to an outer end 16 the first side edge 3 in a shortened section 17 is shortened.
  • In the in the 1b illustrated, so far preferred embodiment is the locking lip 7 in the shortened section 17 opposite the rest of the section 18 the first side edge 3 shortened so much that the locking lug 12 in a direction parallel to the panels 1 . 2 and perpendicular to the side edges 3 . 4 in the shortened section 17 do not survive against each other, ie no supernatant 15 form. In the shortened section 17 the first side edge 3 rather results between the locking lip 7 and the locking nose 12 A gap 19 ,
  • The locking lip 7 is in the direction of the first side edge 3 in the shortened section 17 Curved S-shaped, leaving between the shortened section 17 and the adjacent non-shortened section, ie remaining section 18 , the first side edge 3 no corners or edges are present. In the remaining section 18 engages behind the locking lip 7 the locking nose 12 so that the corresponding locking surfaces 13 . 13 ' abut each other and the two interconnected panels 1 . 2 in a direction perpendicular to the panels 1 . 2 are securely locked together.
  • The in the 2a and 2 B represented panels 21 . 22 also have a first side edge 23 and a second side edge 24 on, which is integral with the carrier plates 34 the first and the second panel 21 . 22 are connected. The profiles of the first and second side edges 23 . 24 correspond essentially to the profiles of the 1a and 1b shown side edges 3 . 4 , Unlike the first panel 1 of the 1a and 1b is at the first panel 21 of the 2a and 2 B the locking lip 27 in a plurality of spaced-apart, shortened sections 37 . 37 ' . 37 '' shortened. Two of the shortened sections 37 . 37 ' are in the illustrated and so far preferred embodiment immediately adjacent to the outer ends 36 . 36 ' the first side edge 23 arranged while another ver short section 37 '' the locking lip 27 substantially centered to the longitudinal extent of the first side edge 23 is arranged.
  • As between the shortened sections 37 . 37 ' . 37 '' and the rest, sections 38 in which the locking lip 27 is not shortened, a curved transition of the locking lip 27 is provided results in the longitudinal direction of the first side edge 23 a wavy shaped locking lip 27 , The locking lip 27 only partially engages behind the opposing locking lug 32 with the formation of a supernatant 35 , in the remaining sections 38 , In the shortened sections 37 . 37 ' . 37 '' are the locking lip 27 and the locking nose 32 by contrast, through a gap 39 spaced apart.
  • In the figures 3a and 3b is a first panel 41 and a second panel 42 with a first side edge 43 and a second side edge 44 shown in the preceding 1a to 2 B shown first side edges 3 . 23 and second side edges 4 . 24 in principle similar. In contrast, however, is the locking lug 52 the locking spring 49 shortened in sections, so that the width b of the supernatant 55 between the locking lip 47 and the locking nose 52 along the two interconnected, integral with the carrier plates 54 trained side edges 43 . 44 varied. In the illustrated embodiment, the locking lug 52 the second side edge 44 only in the directly on the outer ends 56 . 56 ' the second side edge 44 adjacent, shortened sections 47 . 47 ' shortened so that the locking lug 52 in the direction of the two interconnected side edges 43 . 44 has a curved shape. The locking lip 47 and the locking nose 52 are in the shortened sections 57 through a gap 49 spaced apart.
  • In the in the 4a and 4b represented panels 61 . 62 are a whole series of shortened sections 77 along the locking nose 72 each spaced from each other. The locking nose 72 is therefore undulating with a substantially uniform wavelength of about 2.5 cm in the direction of the two interconnected side edges 63 . 64 educated. Here are the locking lip 67 and the locking nose 72 in the shortened sections 77 through column 79 spaced apart. Only in the remaining sections 78 engages behind the locking lip 67 the adjacent locking nose 72 , which in this way a supernatant 75 form.
  • Further, the panel has 61 on the locking groove 68 opposite side of the locking lip 67 a elasticity groove 81 on. However, this elasticity groove is not mandatory. Furthermore, a corresponding elasticity groove could also be required in the 1a to 3b represented panels 1 . 2 . 21 . 22 . 41 . 42 be provided.
  • Not It is shown in detail that at the same time both the locking lip the first side edge and the locking lug of the second Side edge may have shortened sections. The locking lip and the locking lug can be shortened so that the shortened sections facing each other in the connected state of the side edges or spaced apart in the direction of the connected side edges are.
  • At the third side edges 20 . 40 . 60 . 80 and fourth side edges 20 ' . 40 ' . 60 ' . 80 ' in the 1a to 4b illustrated carrier plates 14 . 34 . 54 . 74 For the sake of clarity, no connection profiles are shown. If necessary, at the third side edges 20 . 40 . 60 . 80 and the fourth side edges 20 ' . 40 ' . 60 ' . 80 ' , which are preferably the long narrow edges of the panels, also connecting profiles may be provided to the panels 1 . 2 . 21 . 22 . 41 . 42 . 61 . 62 on all four side edges with other similar panels 1 . 2 . 21 . 22 . 41 . 42 . 61 . 62 to connect to a surface. The third side edge may be configured like the first side edge and the fourth side edge as the second side edge. However, it can also be provided that connection profiles are provided on the third side edge and the fourth side edge, which are connected to one another in a different way as the first side edge and the second side edge. In particular, these are so-called angle profiles. When connecting the panels are first bent against each other, then inserted into each other and then pivoted in a common plane.
  • The illustrated panels 1 . 2 . 21 . 22 . 41 . 42 . 61 . 62 have a high-density fiberboard (HDF) as a carrier plate. But it would also be possible to use a medium-density fiberboard (MDF), a chipboard, an Oriented Strained Board (OSB), a plastic plate or a plate made of a plastic / wood material mixture as a support plate.
  • In the 5 is schematically a method for the production of panels 100 of the type described above. First, prefabricated carrier plates 101 in a direction parallel to the long narrow edges of the carrier plates 101 on a first group of milling tools 102 passed by. The illustrated, prefabricated carrier plates 101 have a laminate coated with at least one decorative paper and have been sawn from a larger material plate with the desired dimensions. The carrier plates 101 consist of a wood material.
  • By passing the carrier plates 101 at the first group of milling tools 102 becomes a third side edge 103 and one of these opposite side edges 104 from the carrier plate 101 worked out. The third side edge 103 and the fourth side edge have corresponding profiles that allow the third side edge with a fourth side edge 104 a similar panel 100 by angle of the third side edge 103 in the fourth side edge 104 connect to. In principle, however, other profiles could also be on the third side edge 103 and the fourth side edge 104 be provided.
  • After the third and fourth side edge 103 . 104 from a carrier plate 101 have been worked out, the support plate 101 in a direction parallel to the short narrow edges along a second group of milling tools 105 transported. This second group of milling tools 105 works a first side edge 106 and a second side edge 107 from the carrier plate 101 out, with the first side edge 106 a locking lip and the second side edge 107 has a locking nose. The locking lip and the locking lug initially extend essentially from one end of the first side edge 106 or the second side edge 107 to the opposite end of the respective side edge 106 . 107 ,
  • On the second group of milling tools 105 that are like the first group of milling tools 102 Although rotating about a fixed axis of rotation, but otherwise are stationary, follows in the transport direction of the carrier plates 101 an oscillating milling tool 108 , the sections at the first side edge 103 provided locking lip shortened. The oscillating milling tool 108 it oscillates in such a way that the locking lip of the first side edge 106 immediately adjacent to the third side edge 103 is shortened, to such an extent that the locking lip in this shortened section when connecting the first side edge 106 with a second side edge 107 an adjacent similar panel 100 not in a direction parallel to the panel 100 and perpendicular to the two connected side edges 106 . 107 protrudes from the locking lug.
  • The oscillating milling tool 108 it oscillates in a plane parallel to the processed carrier plate 101 and perpendicular to the transport direction of the carrier plate 101 , However, other movement patterns can be adjusted as needed, depending on the design of the side edge.
  • Not It is shown in detail that the at least one oscillating Milling tool, if necessary, in the transport direction of the Carrier plates in front of the group of milling tools may be arranged, which the first side edge and the second Work out the side edge of the carrier plate. Then it will be the locking lip and / or the locking nose sections shortened before the locking lip and / or the locking lug off the carrier plate has been worked out. With others Words is the locking lip and / or the locking lug already with a shortening of the carrier plate milled out because in the shortened section material has already been removed from the carrier plate, where else the locking lip and / or the locking lug would be located.
  • Incidentally, contrary to the in the 5 illustrated embodiment, first the first side edge and the second side edge are machined out of the carrier plates before the third side edge and the fourth side edge is machined out of the carrier plate.
  • About that In addition, the shortening of the locking lip and / or the locking lug before or after the actual working out of the first or second side edge made from the carrier plate. The order of the individual procedural steps for working out The side edges can therefore be reversed in principle. Also, the number of tools used for this purpose is not specified, but should be as low as possible for cost reasons be.
  • It can also provide another oscillating milling tool be comparable to the previously described oscillating Milling tool the locking lugs of the second side edges shortened the support plates. As a result, the number the required milling tools are increased overall, however, it is preferred in the case of a milling tool for shortening the locking lug on the second side edge is provided on the milling tool for shortening to dispense with the locking lip on the first side edge. However, this is not mandatory.
