Description

paneling

The invention relates to a panel with at least one pair of complementary locking means on opposite panel edges, wherein at least one pair of locking ^¬ medium is provided with complementary hook profiles.

For example, floor coverings are produced with such panels; in particular, they are suitable for floating floor coverings.

From DE 20 2008 010 555 a generic panel is known. Whose locking step and the receiving opening are designed such that the heel end during a joining movement initially without elastic deformation of the hook profiles recognition as to fit into the receiving opening and the hooks professional ^¬ le are elastically deformed only in the further course of the joining movement.

It has been shown that a floating laid floor covering ^¬ can be difficult to move with the known panels. Both on a hard base surface, as well as a soft impact sound insulating pad sometimes arise problems in the lock, so that the joints may range occurred irregular shapes ^¬ ßigkeiten on the upper side of the floor covering. The invention is based on the object vorzu a panel ^¬ beat whose complementary locking means so ^¬ can be better connect on a hard subfloor, as well as a soft impact sound insulating mat and lock. According to the invention, the object is solved in that we ^¬ nigstens one of the hook profiles having a compression region. The compression range of the hook profile has a favorable effect on the lockability of the hook profiles. By compressing a hook profile in the compression area, it facilitates the production of the locked state. Because the compression is an elastic deformation, the compressed state is restored after completion of the locking operation. The compression area then resumes a neutral uncompressed shape and exhibits an interlocking action counteracting dislodgement of interlocked panels in a direction perpendicular to the panel plane.

In an advantageous embodiment, the compression region is arranged on an outwardly directed surface of a panel edge. According to a further expedient embodiment of the invention, the panel comprises a top, a bottom, a hull, complementary locking means which are provided in pairs on opposite panel edges, at least one pair of locking means with hook profiles, namely a receiving hook, and this opposite a locking hook, with the Assuming that the receiving hitch rumpffern arranged a hook edge and fuselage angeord ^¬ net has a receiving recess, wherein the receiving ^¬ recess is open to the top, that the locking hook is provided with a rumpfnäher and open to the bottom locking recess and a fuselage arranged Arretierabsatz, the can be inserted in a recess provided perpendicular to the plane of the panel in the receiving ^¬ recess of the receiving hook that the locking hook a fuselage transverse transverse surface and also hull fivefold a vertically acting Arret Having this contour, that the receiving hook closer to the fuselage has a transverse joint surface and also closer to the fuselage a form-fitting contour that mates positively with the hull-distant locking contour of the locking hook, so that a locking vertically mounted to the plane of the panels can be effected that the Arre ^¬ animal hook hull located closer to a Horizontalverriege- averaging area has at its locking step that the on ^¬ acceptance hook arranged hull away a Horizontalverriege- lung surfactant comprising in the receiving recess, in that on the pick-up hook has a receiving opening is formed by wel ^¬ the locking shoulder can be inserted substantially in the joining direction in the receiving recess, wherein the locking contour and the positive locking contour form an upper latch, wherein the Arretierkontur has a female locking element or a male detent element, and wherein the form ^¬ final contour to a locking contour complementary female detent element or male detent element, wherein the male detent element and / or the female detent element of the locking hook has an upper compression region with a locking contour with increased compressibility, and that the male detent element and / or the female locking element of the receiving hook has an upper Kompressionsbe ^¬ rich with a receiving contour with increased compressibility.

When the locking shoulder is inserted into the receiving recess of the receiving hook, it comes on the one hand to a contact between Arretierkontur and form-fitting contour. In addition, there is a contact between the Horizontalver- locking surfaces of locking hook and receiving hooks. The horizontal locking surface of the locking hook slides down the horizontal locking surface of the receiving hook; Together they form an abutment. During the joining movement, a surface pressure arises between the locking contour and the positive locking contour, namely when the compressibly designed locking contour comes into contact with the compressible receiving contour. A then occurring compression of these two areas makes it possible to produce a positive connection, which causes perpendicular to the plane of the Panee- le locking / latching. The compressibility of locking contour and receiving contour is designed so that a point load occurring in these areas is generated, or a local limited ^¬ surface pressure, which also causes only a localized compression in these areas. The compression essentially occurs in the material at the point of contact at which the point load / surface pressure acts. The Kompressi ^¬ bility is increased in other words, to the extent that a possible counteract off-mentioned contact point occurring Tenden other deformation of the hook profiles. For example, a bending of the hook profiles is counteracted.

For the construction of a floor covering, it has been found ^¬ that panels on a soft surface can be easily installed and locked when the hook profiles are designed so that is counteracted off the aforementioned contact point deformation of the hook profiles.

An expedient development provides that the hook edge of the receiving hook and the Arretieraussparung the locking hook forms a lower latching, in which hull fists on the hook edge of the receiving hook a female locking element or male locking element is provided, and wherein the locking recess fuselage close to a complementary female locking element or male locking element has. The above-mentioned further development can be further promoted by the fact that the male latching element and / or the femal ^¬ che latching element of the locking hook having a lower Arretierkon ^¬ structure with increased compressibility, and that the male latching element and / or the female engaging member of the female hook, a lower receiving contour with has increased Kom ^¬ pressibility.

Another benefit is seen when the hull is at least partially made of wood-based or wood-based material. consists of parts.

Alternatively, the hull may at least partially consist of a plastic.

According to one embodiment, the hull is provided as a carrier plate which consists of a plastic or of a wood-plastic composite material (WPC). The Trä ^¬ carrier plate is formed for example of a thermoplastic, elastomer or thermosetting plastic. Furthermore, recycled materials from the named materials can be used within the scope of the invention. Well plate material polyolefins (at ^¬ game as polyethylene (PE), polypropylene (PP), polyamides (PA), polyurethane (PU), polystyrene (PS), acrylonitrile-butadiene is preferably used, particularly from thermoplas ^¬ tischem plastic such as polyvinyl chloride, Styrene (ABS), polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polyether rethereketone (PEEK) or mixtures or co-polymers, plasticizers which, for example, may be provided independently of the base material of the carrier plate in a range of 0 ^ ^ wt .-% to 20 wt .-%, in particular 10 wt .- ^%, preferably ^ 7 wt .-%, for example in the range of ei ^¬ nem ^ 5 wt .-% to 10 ^ A suitable plasticizer includes, for example, the plasticizer marketed under the trade name "Dinsch" by BASF

Plasticizer copolymers, such as acrylates or methacrylates, be provided.

In particular, thermoplastics also offer the advantage that the products made from them can be recycled very easily. It is also possible to use recycled materials from other sources. This provides another way to reduce the cost Her ^¬ position. Such carrier plates are very elastic or springy, which allows a comfortable impression when walking and also can reduce the occurring noise when walking in comparison to conventional materials, thus an improved impact sound insulation can be realized.

In addition, the above-mentioned backing plate offers the advantage of good water resistance since it has a swelling of 1% or less. This is true in a surprising way in addition to pure Kunststoffträgem for WPC materials, as they are explained in detail below.

Here, by way of example, a wood and a polymer may be suitable, which may be present in a ratio of 40/60 to 70/30, for example 50/50. As polymers ingredients as polypropylene, Po ^¬ lyethylen or a copolymer may be used from the two aforementioned materials. Such materials offer the advantage that they can be formed in the process described above to a carrier plate even at low temperatures such as in the range of ^ 180 ° C to ^ 200 ° C, so that a particularly effective Prozessfüh ^¬ tion, for example with exemplary line speeds in a range of 6m / min, can be made possible. For example, for a WPC product with a 50/50 distribution of the wood and polymer shares with an exemplary product thickness of 4.1 mm possible, which can enable a particularly effekti ^¬ ven manufacturing process. Furthermore, very stable panels can be produced, which furthermore have high elasticity, which is particularly advantageous for an effective and cost-effective design of connecting ^elements on the edge region of the carrier plate and Furthermore, with respect to a footfall sound insulation can be beneficial. Further, the aforesaid good water treaty ^¬ friendliness can be made possible with a swelling of less than 1% in such WPC materials. Here WPC materials Kings ^¬ nen example, stabilizers exhibit and / or other additives ^¬, which is preferably present in the plastic portion.

Furthermore, it may be particularly advantageous, that comprises the carrier plate Trä ^¬ a PVC-based material or consists thereof. Also, such materials can be used in especially before ^¬ some manner for quality panels, which are used without problems as well as in damp rooms. Furthermore, also PVC-based materials for the carrier plate for a particularly effective manufacturing process offer, since about line speeds of 8 m / min can be possible in an exemplary product thickness of 4.1 mm, a particularly effective manufacturing process ermögli ^¬ chen can. Furthermore, such carrier plates have an advantageous elasticity and water compatibility, which can lead to the aforementioned advantages.

Particularly suitable here are talc or calcium carbonate (chalk), alumina, silica gel, quartz flour, wood flour, gypsum.

In order to determine the particle size distribution, it is possible to resort to the generally known methods such as, for example, laser diffractometry, with which method particle sizes ranging from a few nanometers to several millimeters can be determined. It is thus also possible to determine D50 or D10 values which are 50% or 10% of the measured particles smaller than the specified value.

According to a further embodiment, the material of the carrier plate may comprise hollow microspheres. Such additives can in particular cause the density of the support plate and thus of the panel produced can be significantly reduced, so that a particularly simple and cost-effective transport and also a particularly comfortable installation can be guaranteed. In this case, in particular ^¬ sondere by inserting hollow microspheres, a stability of the panel produced are ensured which is not significantly reduced as compared to a material without the hollow microspheres. Thus, stability is sufficient for most of the applications. Under hollow microspheres can be understood in particular structures that have a hollow body and have a size or a maximum diameter, which is in the micrometer range. For example, usable hollow spheres may have a diameter which is in the range of from 5 to 100 microns, for example, 20 to 50 microns. As material of the hollow microspheres, basically any material is considered, such as glass or ceramic. Furthermore, due to the weight

Plastics, such as the plastics used in the support material, such as PVC, PE or PP, be advantageous, these being optionally, for example, by suitable additives. may be prevented from deforming during the manufacturing process.

The hardness of the material of the carrier plate may have values in a range of 30-90 N / mm ² (measured according to Brinell). The modulus of elasticity can range from 3,000 to 7,000 N / mm ² .

According to a further embodiment of the invention, the increased compressibility can be provided by the selection of the material of the hull, which has a hardness (Bri ^¬ nell) in a range of 30-90 N / mm ² . In addition, the material of the hull may advantageously have an E modulus in a range of 3,000 to 7,000 N / mm ² to obtain the increased compressibility.

According to a preferred embodiment of the invention, it may be provided that the carrier plate is produced by means of a method which has at least the following method steps:

a) providing a pourable carrier material, in particular ^¬ a granulate,

b) arranging the carrier material between two belt-like conveying means,

c) shaping the substrate, under the action of Tempe ^¬ temperature to form a web-shaped carrier, d) compressing the carrier

e) treating the support under the action of pressure using a dual-band press, wherein the support is cooled in or in front of the dual-band press.

It has surprisingly been shown that it can be made possible by the method described above to combine a particularly advantageous preparation, in particular a Trä ^¬ gers or a support plate for a wall or floor panel with materials which for the production of the support of the panel due to their excellent intrinsic Shafts are particularly preferred. In this case, by a combination of the above-described method steps, a production method, in particular a carrier with herausra ^¬ ing materials of a decorated wall or Bodenpaneels be made possible with improved efficiency, wel ^¬ ches method also allows the production of highly adaptable and very stable panels that simultaneously have suitable material properties for the inventively provided locking means with a compression region. Thus, it is easy to produce panels which may have preferred properties.

In accordance with a further embodiment of the method described above, a further cooling of the carrier prior to a subsequent further processing can be provided as method step f).

First, according to the present method, a carrier or a core is generated. The above-described drive Ver ^¬ comprises first therefor according to process step a) providing a pourable carrier material. The carrier material serves as the basis for the production of insbeson ^¬ particular plate-shaped carriers for panels. It may be present, for example, as a uniform material or as a material mixture of two or more materials. The carrier material or at least a part of the carrier material should have a melting point or a softening point ^¬ to the carrier material in a further method step by the action of heat to form, as explained in detail below. In a particularly advantageous manner ^¬ the carrier material can be provided as a pourable solid substance or as a granulate, wherein the granulate purely by way of example may comprise 10mm depending on the material used as a grain size in a range of> lOOym to -S. This allows a prob ^¬ lemlose storability and also a particularly good adapters tierbarkeit to a desired material composition. Because in particular in granular form, a particularly homogeneous mixture of different components can be produced with a particularly defined mixture having a precisely adjusting ^¬ cash composition is obtainable. By way of example, so-called dry blends can be used, so dry Art ^¬ materials in powder with additives. In addition, a granulate, in particular in the above-Größenbe can ^¬ rich distribute very homogeneous and very defined further on a base, so that a carrier can be produced with a highly defined profile of properties. A before ^¬ ferred packing or distribution of the carrier material may in this case a deviation of the bulk density of <5%, in particular -S comprise 3%.

According to method step b) the pourable, in particular granular carrier material between two band-like För ^¬ dermitteln is arranged. In detail, a lower bandarti ^¬ ges conveyor is moved circumferentially and in a DEFINE ^¬ th distance to the lower conveyor an upper belt-like conveying means is circumferentially moved. The Trägerma- can TERIAL applied onto the lower conveyor who ^¬ and then limited by the lower and upper conveyor ^¬ medium. By an exact scattering can be dispensed with since ^¬ on a lateral boundary. By means of the two conveying means, the carrier material can thus be conveyed to or through individual processing stations and processed into a carrier. Furthermore, the carrier material may be formed already in this method step before ^¬. Thus, the belt-like conveying means can take on two functions, namely that of a transporting means and that of a mold.

In this case, the tape-like conveying means at least in the area of the Be ^¬ dual band press, as described below, at least partially of Teflon or from polyvinyl lytetrafluorethylen (PTFE) may be configured. For example, the bands can be made entirely of polytetrafluoroethylene. be formed, or it can be used tapes, which are provided with an outer coating of polytetrafluoroethylene. In the latter case, glass fiber reinforced plastic bands or steel bands can be used. By such conveying this material, due to the properties Antihaftei- a particularly defined to be erzeug ^¬ bar at ^¬ play smooth surface of the carrier generated. Thus it can be prevented that the conveyed carrier material adheres to the conveying means and thus adversely affects the surface structure directly or by adhering material in a next cycle. In addition, polyterafluoroethylene is resistant to chemicals as well as against decomposition even at high temperatures, so that on the one hand a problem-free temperature treatment of the carrier material is possible and the funding is also stable for a long period of time. In addition, the carrier material can be freely selectable.

The conveyor means can pass through the entire apparatus ^¬ thereby, or may be interrupted and be configured as multiple conveyor means.

The discharging of the carrier material according to method step b) can be realized in particular by means of one or a plurality of scattering heads, which can discharge the carrier material in a defined manner. With regard to the scattering heads, these may for example be part of a scattering unit and have at least one rotating scattering roller. In ^¬ example, a funnel can be provided, which defines the material to be discharged discharged on the scattering roller. In this case, a doctor may further be provided which sweeps the material in recesses of the roller. Subsequently ^¬ ßend the material with the aid of a rotating Bürstwal ^¬ ze of the spreading roller may be discharged, whereby it hits against an impact surface and slides from there to the conveying means. In order to regulate the spread, a spread width setting may be further provided. In this edition staltung can be a particularly homogeneous discharge of the carrier material, which can equally lead to a homogeneous carrier with defined quality.

For example, a scattering head or two, three or more scattering heads can be provided. As a result, the carrier can be particularly tailor-made in a particularly simple manner, for example by providing a desired material mixture. In this embodiment, the mixture can be easily adapted during the manufacturing process or between batches, so that a particularly large variability can be ensured. Moreover, a mixture for the carrier material only immediately before processing can be generated by a different placement of a ^¬ individual spreading heads, so that a negative influence of the various components with each other and a consequent reduction in the quality of the prepared support can be prevented.

In a further step, according to method step c), a shaping of the carrier material arranged between the band-like conveying means takes place under the action of temperature or heat. In this method step takes place by the applied heat or heat thus melting or softening of the carrier material or at least part thereof, whereby, for example, the granules can be formed. In this state, it can homogeneously fill the receiving space forming between the conveying means and thus form a web-shaped carrier which can be further treated.

The thus formed web-shaped carrier can simultaneously with or after the following process step c) according to the method ^¬ step d) are compressed. This process step can be carried out in particular in a suitable press or ^roller . There is thus here a first compression of the web-shaped carrier. In this step, the wearer can already substantially obtained its desired thickness, so that in the following processing steps only a slight compression needs to take place and thus the further steps can be particularly gentle, as will be explained in detail below. It can ^{insbesonde ¬} re be ensured that the temperature of the carrier has cooled so far that a suitable compressibility while preserving the desired result can be made possible. In a further process step e) a white ^¬ teres treating the support under the action of pressure, using a two-belt press will now be given. In particular, the surface properties of the carrier can be adjusted in this method step. For example, in this process step, in particular a smoothing of the surface SUC ^¬ gene. To this end, the previously compressed support can be treated under the action of pressure, in particular, the pressure can be selected to be small so that this second compression only takes place in a very small area , By way of example, a compression in a range of <10%, ^ 5%, in particular ^ 3% of the total thickness of the carrier before compression can take place. For example, densification may be in a range of 0.2-0.3mm with a panel thickness of 4.5mm. Thus, the design of the processing device in this process step can be selected in particular depending on a desired adjustment of the surface properties, which can be particularly gentle. Thus, the dual-band press can serve as a calibration zone, in particular for adjusting the final surface properties as well as the thickness of the carrier.

In particular, the use of a two-band press can be advantageous, since particularly gentle compression steps are possible with such a press and furthermore the surface quality is adjusted in a particularly effective and defined manner can be. Furthermore, the use of a belt press may in particular allow for high line speeds, so that the entire process especially high throughput can ermögli ^¬ chen. For example, such a belt press, which generally has a fairly long processing space in the conveying direction of the carrier, a plurality of heating zones have ^¬ that a temperature profile and, therefore, effective adjustment of the surface properties may allow niengeschwindigkeiten even at high Li-.

In addition, an especially uniform and defined adjustment ^¬ bare tape tension of the two-belt press can be made possible for example by the provision of pneumatic cylinders, so that the setting of the surface finish as well as the com- pression can be particularly accurately. In this case, the belt press may, for example, be coated with steel strips without coating or with polyterafluoroethylene, and / or may be tempered by, for example, a thermal oil heater.

Smoothing or adjusting the surface quality may mean in this step that although the uppermost surface is smoothed, structures or pores already introduced, for example, are not affected or are only influenced within a defined range, so that they remain intact even after this process step desired manner may be present, insofar as this is desired. This may be possible by the use of a belt press with ge ^¬ eignetem temperature profile and with suitable pressure values in particular.

In this case, it is further provided that the carrier is cooled before or in the dual-band press and thus, in particular, during or before method step e), in particular below the melting point or the softening point of a plastic constituent of the carrier material. It can be a cooling only in a limited range, so that the carrier still has a compared to the room temperature (22 ° C) increased temperature, but below the previously set ^¬ th elevated temperature and thereby preferably and depending on the plastic used, below the

Melting point or the softening point of the plastic contained in the Trägerma ^¬ material. This can be done for example by a suitable choice of the temperature of the temperature control devices which are found in loading the two-belt press, or the carrier may be disposed before the two-belt press temperature control medium be less heated cooled Bezie ^¬ hung example in particular through. In particular, by cooling the wearer a particularly high hochwerti ^¬ ges surface image can be formed, since the belts of the double belt press, which may be configured as polytetrafluoroethylene (Teflon), are spared. Furthermore, a bowls or an occurrence of voids or pores can be prevented, so that the surface of the carrier can be particularly high quality. Suitable temperatures are, for example and not restrictively, in a range of below 130.degree. C., for example in a range of> 80.degree. C. to -115.degree. C., for example of 120.degree. C., for polyethylene.

In the course of further cooling of the web-shaped support is then carried out in a further process step ^¬ f) if necessary. The carrier may be cooled by providing a cooling device with defined cooling stages to a temperature in particular, which corresponds to the room temperature or purely exemplary Be ^¬ rich of up to 20 ° C in a above. For example, there may be a plurality of cooling zones to allow for defined cooling of the support.

After cooling of the carrier produced, the carrier can first be stored in a web-like form or as an isolated plate-like carrier, and the process can initially be completed. Preferably, however, close immediately further treatment ^steps , which can be realized without grinding on, for example, in order to process the provided carrier in such a way to produce a finished panel, as explained in detail below.

Another benefit is provided when material recess (s) of the lower and / or upper Arretierkontur and the lower and / or upper receiving contour are provided, wherein the Materialaussparung (s) increase the compressibility locally by acting at the moment of locking on the receiving contour Force acts on a smaller area. The Incr ^¬ te surface pressure creates a greater way of compression. In addition to the selection of a suitable material for the carrier plate, there is thus a konstruktionsstechni- see possibility to influence the compressibility at the desired locations. Thus, for example, gap-like material recesses can be created.

The underside of the receiving ^hook is preferably in ei ^¬ ner plane which is identical to the plane of the underside of the panel.

Each female engaging element conveniently has a detent ^¬ surface which is directed toward the top or bottom of the panel, and each male locking element includes a complementary latching surface which is directed towards the respective other side of the panel, so that the locking surface of the female ^¬ union latching element counter cooperates with the latching surface of the male pendant ^¬ chen detent element in the locked state of two panels moving apart locked panels perpendicular to the panel plane. Preferably, the locking surface of the female Rastele ^¬ ment contacts the locking surface of the male locking element in the locked state of two panels. In this way the unte ^¬ re latching contributes to a fixed locking perpendicular to the Level mounted panels at.

Alternatively, a gap may be provided between the latching surface of the female latching element and the latching surface of the associated male latching element in the locked state of two panels. This can simplify the assembly process if, for example, a relative displacement between the transverse edges is to be accomplished. A gap of a few tenths of a millimeter appears sufficient, preferably approx. 0.1 mm. The panels can be designed so that during the joining ^¬ movement first the upper catch and then the lower latching is completely assembled.

The horizontal locking surfaces of the hook profiles are preferably inclined relative to the surface normal of the top by an angle of 0 ° to 25 ° and in the locked Zu ^¬ stood two panels arranged substantially parallel to each other. The angle of inclination depends essentially on the configuration of the locking contour and the positive locking contour, in particular of where the female or male locking element is arranged. An inclination angle between 7 ° and 25 ° has proven to be favorable. There may be a tendency for a lower inclination to be provided if the arresting contour is provided with the female detent element and the positive-locking contour has the matching male detent element. The smaller the angle of inclination, the higher is the holding force against being pulled apart in the plane of the assembled panels and perpendicularly to the Subject Author ^¬ fenden transverse edges. Preference is therefore tilt angle <7 ° and particularly favorable is an inclination angle of about 3 °. In principle, a negative inclination angle of the two horizontal locking surfaces is possible. This would achieve a locking effect perpendicular to the panel level. When a female and male detent element is interchanged, a larger tilt angle is generally It is expedient for the locking contour to be connected to the positive locking contour.

The hook edge of the receiving hook may have a sliding ^{inclination ¬} hull. It is a surface that is inclined relative to the panel plane, and simplifies the insertion of the hook edge in the locking recess of the locking hook.

The Arretierabsatz has in a preferred embodiment on its fuselage side on a sliding bevel. The sliding bevel is a surface that is inclined relative to the panel ^¬ plane, and simplifies the insertion of the Arretierabsatzes in the receiving recess of the receiving hook. It is expediently designed so that it comes into contact with the shape ^¬ final contour. At the same time, the horizontal locking surface of the locking hook slides down the horizontal locking surface of the receiving hook and forms an abutment. In this way arises during the joining movement by the contact between the slip and the form-fitting contour surface pressure. In particular, a compression of the locking contour and the receiving contour. The compression of these areas makes it possible to produce a positive fit. The slip ^slope he ^¬ facilitates the locking of two panels.

The compressible areas of the receiving contour and the locking contour are elastically compressed. During the further joining movement, the locking contour passes the form-fitting contour until both have reached a position in which they fit together in a form-fitting manner. So a closed joint can be achieved. The horizontal locking surfaces of the two hook profiles are then preferably against each other.

In order to connect the panels easily, a pair of pivoting profiles may be provided, namely a groove profile with Undercut in a groove wall and matching a spring profile with undercut on the corresponding side of the spring. This has the advantage that the panels can be expedient ^¬ ßigerweise mounted so that a new panel attached to a swivel profile complementary to the profile of a pivot already mounted panel, and is in the plane ge ^¬ pivots the advantage. In addition to the advantageous the hook profile of the new panel can then be interlocked with the Ha ^¬ kenprofil of a panel in the same row of panels simultaneously. At the same time is lowered by the pivoting movement and the locking hook of the new panel in a scissor-like movement substantially in a vertical plane and inserted into the receiving hook of a lying in the same row of panels panel. During the scissor-like movement, the arresting shoulder first projects into the receiving opening only at one end of the panel edge. When progression ^¬ th of scissor-like joining movement of the locking step gradually comes into the receiving opening. When the panels are finally in one plane, the locking contour and the form-fitting contour are exactly matched; the transverse joint surfaces touch and form a closed joint.

At the top of a transparent cover layer may be vorgese ^¬ hen and / or a decorative layer, is visible through the transparent outer layer of the hull or the decorative layer. The transparent cover layer serves to protect the as ^¬ down underlying layer. It may be provided with means which reduce wear, for example Korundparti ^¬ kel, glass particles, etc., and / or themselves consist of chemically completely cure tendem resistant material, for example a cured by ultraviolet light resist or a curable resin layer such as a melaminhal - resin layer.

On the underside of the panel, a counteracting layer may be provided. This acts as a balance to those at the top te provided layers to counteract a delay of the panel.

In addition, a possibility and thus a method is ^¬ proposed, such as a new square panel, which is provided with two longitudinal edges and two transverse edges, simultaneously locked to an already assembled from identical panels previous row of panels and an already mounted iden ^¬ table panel the same row of panels can be with the proviso that a first longitudinal edge is connected by pivoting the new panel in the plane of the assembled panels form-fitting with the previous row of panels, at the same time a first transverse edge of the new Pa ^¬ neels by a scissor-like movement in positive engagement with a second transverse edge of the assembled panel of the same row of panels, with the further Maßga ^¬ be that the first transverse edge of the panels each having a first transverse joint surface and the second transverse edge of Panee ^¬ le each having a second transverse joint surface, wherein the first transverse joint surface at the demj enigen end, which faces the first longitudinal edge, is brought into contact with the second transverse joint surface of the assembled panel of the same row of panels, wherein the positive connection of the longitudinal ^¬ edge and the transverse edge of the new panel is made by between the new panel and the previous panel a longitudinal joint gap and a transverse joint gap is produced, which shows the wedge tip of the transverse joint gap in the direction of the previous row of panels and shows the wedge tip of the longitudinal joint gap in the direction of the free second transverse edge of the new panel, and the new panel is finally mounted in the plane of the new panel Panels is pivoted, wherein the positive engagement of the transverse edges and longitudinal ^¬ edges are completely joined together and the wedge-shaped Fu ^¬ genspalte be eliminated. Due to the transverse joint gap, the transverse edges are shifted slightly in their longitudinal direction. The offset corresponds to the gap at the furthest point of the transverse joint gap. In order to ^adjust the offset, the transverse edges must be movable relative to each other / displaceable. It is favorable if at least one latching, for example the lower latching is designed such that a small gap, for example 0.1 mm, is provided between latching surfaces in order to facilitate the mobility of the transverse edges.

The longitudinal joint gap can be created by the new Pa ^¬ neel temporarily brought from its parallel orientation to the previous Paneelreihe and the wedge tip of Längsfugen ^¬ gap is generated at the distal end of the first longitudinal edge of the new panel.

On the other hand, the longitudinal joint gap can be created by temporarily bringing the new panel out of its planar form, in which it is arched out of its panel plane in the direction of its top side.

Fig. 8a-8c is a schematic representation of the construction of a floor covering with panels according to the invention. Fig. 1 shows a first edge pair of an inventive

Panels 1 and 1 ', respectively. In this figure, a longitudinal ^¬ edge pair of a rectangular panel is shown. The

Longitudinal edge pair has complementary pivoting profiles S. As such, all well-known in the art form-fitting profiles can be provided, which can be positively connected by obliquely applying a new panel to a previous panel ^¬ row and then pivoting a new panel 1 'in the plane of the assembled panels. The complementary pivoting profiles S according to FIG. 1 comprise a groove profile 2 and a spring profile 3. The groove profile 2 has an upper groove wall 2a, which is shorter than the lower groove wall 2b. The lower groove wall is also provided with a rear-cut recess 2 c for the spring profile 3. The recess 2c also has a horizontal locking surface 2d. The spring profile 3 is provided with a Fe ^¬ deroberseite 3a and a spring underside 3b, the is arranged substantially parallel to the top 4 'of the new panel 1'. The spring has a rear base ^¬ section 3c and a horizontal locking surface 3d, which cooperates with the horizontal locking surface 2d of the lower groove wall 2b. The inclination of the new Pa ^¬ neels 1 'is indicated in Fig. 1 indicated by the position shown in dashed lines of the spring profile 3'. The spring ^¬ bottom is placed on the longer lower groove wall 2b. The new panel 1 'is advanced with the nib in the groove profile 2 and the new panel 1' then pivoted in the plane of / the assembled panels. The sub ^¬ sides 12 and 12 'of the panels 1 and 1' are then in one plane.

A second edge pair of a different type is shown in sections in FIGS. 2a to 2c. This edge pair is seen at the transverse edges of the panel 1 and 1 'before ^¬ . The panels 1 and 1 'are identical panels. Each individual panel has complementary profiles 5 and 6, respectively, at opposite transverse edges of an edge pair. In the panel 1, therefore, the edge, not shown, on a profile which is identical to the profile 5 of the panel 1 'and in panel 1' is not shown edge iden ^¬ table with profile 6 of the panel. 1

For the sake of completeness, it is pointed out that embodiments with quadrangular panels are also possible whose first edge pair (longitudinal edge pair) is formed with complementary profiles that are identical to the profiles of the second edge pair (transverse edge pair).

The series of Figures 2a to 2c illustrates in several steps the basic sequence of the joining movement purpose

Connection and locking / locking of the panels 1 and 1 '.

The complementary profiles 5 and 6 of each panel 1 and 1 'form complementary locking means in the form of hook profiles H. The hook profile of the panel 1 forms a receiving hook 7 and the hook profile of the profile 1 'a locking hook 8, which fits into the receiving hook. In this case, the two hook profiles are designed so that a locking or an upper latching takes place, which counteracts a movement apart of the panels in the reverse direction. The panels 1 and 1 'can not be released from each other again after locking / latching perpendicular to the plane of the assembled panels. Each panel 1 or 1 'comprises a hull 9 be ^¬ 9 way 9', on which the mentioned complementary locking means are arranged. The upper side 4 of the panel ^¬ le forms each a Nutzoberfläche. The hull, which can also be referred to as a carrier plate, has a wood-plastic composite in the present exemplary embodiment.

Material (WPC) on. Alternatively, the support plate may consist of a plastic, for example a thermoplas ^¬ tables, elastomeric or thermosetting plastics material or recycled material of the aforementioned materials. On the receiving hooks 7 is a hook rim 10 and rümpfnäher a receiving recess 11 is provided. The receiving recess 11 is open to the top 4.

The locking hook 8 is provided with a rumpfnäher arranged and open to the bottom 12 locking recess 13 and has fuselage a locking shoulder 14. The arresting paragraph fits in a vertical joining direction T in the receiving recess 11 of the receiving hook 7. Furthermore, the locking hook 8 has a hull-distant transverse joint surface 15 and also fuselage a vertically locking locking detent 16 acting on. The receiving hook 5 has a transverse joint surface 17 close to the sheath and likewise close to the sheath to a form ^¬ final contour 18, which mates with the locking contour 16 of the locking hook 8 positively. In this way, an upper latch V _{0 is} formed, with which a locking ment perpendicular to the panel plane is effected.

8 In addition, the locking hook rumpfnah arranged a horizontal latch surface 19 which is arranged at its Arre ^¬ animal batch fourteenth Fittingly, the receiving hook 7, arranged hull-distant in the receiving recess 11, a horizontal locking surface 20 which cooperates with the horizontal locking surface 19 of the locking hook 8 ^¬ .

The receiving hook 7 is provided at its receiving recess 11 with a narrowed receiving opening 21. The Arretierabsatz 14 can be inserted substantially in the vertical joining direction T in the receiving recess 11, that is in a plane perpendicular to the plane of the locked panels.

According to FIGS. 2a to 2c, the panel 1 with the receiving hook 7 is arranged on a solid base (not shown). The locking shoulder 14 of the panel 1 'is lowered for the purpose of locking the panel edges perpendicular to the panel plane (vertical). The fuselage locking contour 16 of the locking hook 7 has an upper locking contour 23a, which is designed to be compressible and provided with a female Rastele ^¬ ment 16a (recess). The female Rastele ^¬ ment 16 a has a latching surface 16 b, which is directed to the top 4 'of the panel 1', and which projects behind the plane of the transverse joint surface 15 of the locking hook 6. The fuselage close-fitting contour 18 of the receiving hook 7 has ei ^¬ ner upper receiving contour 22a, which is designed to be compressible and provided with a male locking element 18a. The male locking element 18a has a locking surface 18b, which is directed to the underside 12 of the panel 1 and protrudes beyond the plane of the transverse joint surface 17 of the receiving hook 7. In the locked state, the latching surface 18b engages behind the female latching element 16a of the locking hook 8.

The upper receiving contour 22a comprises the male locking element ment 18a. In addition, the shaped top compressible arresting 23a comprises the female engaging member 16a of the Arre ^¬ animal hook 8. The upper arresting 23a comprises, in essence, those material portion forming the locking surface 16b. At one end of the latching surface 16b, the female latching element forms a free tip. Under a punctiform load acting on the free tip from the outside, it gives way; it is elastically compressed and abge ^¬ plates. This happens when the compressible male latching element 18a is punctiform with the free one

Tip of the female locking element 16a is brought into contact. In this case, the male locking element 18a in turn flattened.

The thus created compressibility of the male engaging element 18a and the female engaging element is based Wesent ^¬ union on the material property of the material of Rump ^¬ fes. In the present example, this has a hardness (according to Brinell) of 40 N / mm ² and an E-modulus of 4,000 N / mm ² .

Because of this, the compressibility of the retaining hook 16 arresting 8 can particularly easily be inserted into the positively locking contour ^¬ 18 of the receiving hook. 7

In addition, FIG. 2b shows that the receiving hook comprises at its 7 hook edge 10 having an outer surface which is not in contact with a certain genüberliegenden rümpfnahen surface of the locking hook 8 in quantitative together ^¬ inserted state of two panels.

Figures 3a-3c show a development of the vorbeschrie ^¬ benen embodiment, in which an additional lower catch Vu is provided, which improves the locking action perpendicular to the plane of the panels. For identical design features, identical reference numerals are used in all following figures.

According to Fig. 3a, the locking hook 8 - for the production of a lower catch Vu - with a female Rastele- ment 13a provided. This has a latching surface 13b, which is directed to the top 4 'of the panel 1'. Matching the receiving hook 7 is provided with a male locking element 10a. This has a latching surface 10b, which is directed to the underside 12 of the panel 1, so that it can cooperate with the Rastflä ^¬ surface 13b of the female latching element 13a.

The locking hook 8 is designed so that the Arretieraus ^¬ saving 13 of the locking hook 8 widened during the joining process and at the same time the hook edge 10 is compressed. For this purpose, a compressible designed lower locking contour 23b and the receiving hook a compressibly shaped lower receiving contour 22b is provided on the locking hook 8. The lower locking contour 23b is essentially that material area which forms the female detent element 13a with the detent surface 13b. He has a rümpffern provided on the locking surface 13b free tip, which can be good elastic plates when it comes selectively with the male locking element 10a of the lower receiving contour 22b in contact. Both sides are in contact with each other, namely the male detent element 10a as well as the female detent element at the free tip of the detent surface 13b.

The group of figures 4a-4c shows an alternative to the herein are subject ^¬ engined figure group. In this alternative, the weibli- che and male latching element interchanged that is, the OBE ^¬ re latching V ₀ has been modified so that the locking ^¬ hook 8 has a compressible upper arresting 23a, the latching element 16c is male and a white upwards ^¬ Send locking surface 16d has. To match this, the positive locking contour of the receiving hook 7 has a compressible upper receiving contour 22a with a female detent element 18c and a downwardly facing detent surface 18d. In the locked state, the locking surfaces 16d / 18d contact each other and prevent disengagement of the connected panels in a direction perpendicular to the plane of the panels. The lower catch Vu is on the other hand, identical to the lower catch proposed in groups 3a-3c.

Another alternative is in the group of figures 5a-5c ge ^¬ shows. This differs from the previous group of figures in turn by an exchange of the male and female latching element of the lower catch Vu. Here, the compressible lower locking contour 23b of the Arretierha ^¬ kens 8 a male locking element 13c, while the com ^¬ pressible lower receiving contour 22b of the receiving hook 7 is provided with a female locking element 10c, which comprises a latching surface lOd. The compressibility of the lower locking contour 22b is essentially based on that material region which forms the latching surface 10d.

At one end of the latching surface 10d of the female latching element, a free tip is formed. Under a punctiform load acting on the free tip from the outside, it gives way; it is elastically compressed and flattened. This happens when the compressibly designed male detent element 13c is brought into contact with the free tip of the female detent element 10c in a punctiform manner. In this case, the male detent element 13c in turn gives way and is flattened from ^¬ .

A final alternative is found in the group of figures 6a-6c is ^¬. Here corresponds to the upper latching that of the embodiment of the figure groups 2a-2c / 3a 3c, while the lower latching Vu is identical to the unte ^¬ ren lock, which has been explained with reference to Figures 5a-5c.

Finally, Fig. 7 shows an example of a development of the panel according to the group of figures 2a-2c. From this panel, the panel edge is shown in detail with the receiving hook 7. The finned hook edge 10 has a flat outer surface. It is a compressibly designed upper Receiving contour 22a provided with a male locking element 18e. The special feature of this embodiment be ^¬ is that the male latching element is provided with Materi ^¬ alaussparungen 18f 18e. The male locking element 18e has the basic shape of a rib with an approximately triangular cross-section. The material recesses 18f are pronounced as groove-shaped gaps. The gaps alternate with the remaining rib pieces of the male locking element 18e. In this way, a "comb-like" configuration of the male detent element results, which increases the compressibility of the male detent element, and the chine pieces can expand into the gaps as they are compressed.

In the present example, the groove walls of the material recesses 18f are arranged parallel to one another and perpendicular to the plane of the panel.

Of course, the material recesses 18f can be of any other design which increases the Kompressi ^¬ stability of the male latching element 18e. A variant, not shown, provides that the Nutwän ^¬ de of the material recesses are arranged in planes, which are each inclined relative to the plane of the panel at an acute angle.

Another variant provides for the material recesses to be arranged in such a way that they form cavities in the interior of the compressibly designed material region. These can be as decor with dark ^¬ tet that they are not visible from the outside.

Also, in the female locking elements 10c, 13a, 16a and 18c of the above-described embodiments, those materials can be areas, which are compressed for a locking Müs ^¬ sen, be provided with additional material recesses, which also increase the compressibility in the region of the respective female ^¬ union latching element , For mounting a new panel 24, which is provided with two longitudinal ^¬ edges and two transverse edges, it is proposed according to the figures 8a-8c, as this to an already from identical panels mounted previous row of panels P2 so-like at the same time on an already assembled identical Pa ^¬ neel 25 same Paneelreihe P3 can be locked.

Figures 8a-8c show the preparation of Fußbodenbe ^¬ lags of panels hereof. The rows of panels P1-P3 are shown in ^¬ section-wise. The new quadrilateral panel 24 is shown only schematically. The panels used are an embodiment with egg ^¬ nem pair of longitudinal edges 24a / 24b, which is provided with complementary form-fitting pivoting profiles S and with a pair of transverse edges 24c / 24d, which have complementary hook profiles H. The pivot profiles S are used to connect panels under ^¬ different rows of panels together. The hook profiles H serve in this embodiment to connect panels of the same panel row P3 together. The hook profiles H of the transverse edge pair can be formed as in one of the exemplary embodiments according to FIGS. 2a to 6c.

Fig. 8a shows how a new ^¬ it is assembled panel 24 in the front row of panels P3, which is to be locked, both to the previous row of panels P2 and with a transverse edge 25d of a neighboring panel 25 of the same row of panels P3. The new panel 24 is attached obliquely with respect to the plane of the assembled panels and with one of its pivoting profiles S to the front panel row P2. It is then locked by pivoting into the plane of the assembled panels with the previous panel row P2.

At the same time, the hook profile (locking hook 8) of the new panel 24 provided on the transverse edge 24c also locks with the hook profile (receiving hook 7) of the panel 25 of the same row of panels P3 provided on the transverse edge 25d. The locking hook 8, while the new panel 24 in the Level of the assembled panels is pivoted, simultaneously brought in a scissor-like joining movement with the receiving hook 7 in engagement.

The positive connection of the longitudinal edge 24a and the transverse edge 24c of the new panel 24 is shown in FIG. 8c Herge ^¬ represents by between the new panel 24 and of the preceding row of panels P2, a longitudinal joint gap L and a Querfu ^¬ genspalt Q between the transverse edge 25d of the panel 25 and the transverse edge 24c of the new panel 24 is generated. The wedge tip of the transverse joints gap Q points in the direction of the vorheri ^¬ gen row of panels P2 and the wedge tip of the longitudinal joints gap L 24. When the new panel 24 is finally pivoted into the plane of the assembled panels in the direction of the free second transverse edge 24d of the new panel is the SiGe form fit engagement of the transverse edges 24c / 25d and the longitudinal edge 24a with the preceding row of panels P2 made fully mated and the wedge-shaped joints as Q and L be ^¬ seitigt.

The longitudinal joint gap L is generated by bringing the new panel 24 is temporarily out of its parallel alignment to the previous row of panels P2 and the wedge tip of the longitudinal joints ^¬ gap L is formed at the distal end of the first longitudinal edge 24a of the new panel 24th
