Description

This application takes priority of the earlier application filed with the DPMA on Nov. 23, 2006 DE 10 2006 055 715.8 to which the entire contents of which are incorporated herein by reference, to supplement or in part or in full replace the following description and drawings.

The invention relates to a floor element according to the preamble of claim 1 and a composite formed therewith.

Various types of floor elements are known, such as e.g. simple floor panels, profile panels, laminates and the like. For this purpose, wood- and plastic-containing composite materials are used, which can be installed both indoors and outdoors, such as when creating terraces or boat jetties. Other equally demanding fields of application are e.g. Swimming pools etc.

The laying of such floor elements is particularly difficult if the floor elements no fastening elements, such as tongue and groove elements have that interlock and thus form a solid bond. But also the laying of floor elements that already have such fasteners, such as

Laminates, requires a certain skill. In particular, the conventional tongue and groove elements require precise handling here. Also, this usually only a composite consisting of the same floor elements can be formed. A connection with other floor elements and thus a variation of the composite and / or its overall appearance are hardly possible.

From the FR 2 791 076 a floor element made of plastic is known, which can be joined together with other floor elements to form a composite. The individual floor element has an upper side with a predeterminable surface and a lower side with a support structure and is shaped as a displaceable square edged floor plate. For joining with other floor elements, the floor element has at its edges in each case a plurality of mutually spaced fasteners ("organes lateraux males and femelles d'assemblage"), which have protruding notches, which engage in joining the floor element with another or other floor elements in there provided counter-locking points , So that the floor element is particularly suitable for use in outdoor areas, passages ("couloirs") are provided on the underside, which correspond with openings ("ajours") in the surface in order, for example, to drain down trickling water. In addition, the bottom element may have perforations for venting.

From the DE-U1-85 01 206 is known a floor grid that is composed of several plastic floor panels together. Each bottom plate has at least one border brackets which engage in a border of an adjacent bottom plate. Since it is a permeable floor grate, no special measures for the drainage of rain water and the like must be provided there.

Other floor elements and floor coverings or wall coverings in general are about DE 20315836 U1 or FR 2365675 or US 6,324,796 B1 or DE 102005017443 B3 or GB 1600823 or WO 92/20885 or WO 02/08542 known. However, no special solutions are described here, which relate to the drainage of rainwater or the like.

However, it is desirable to achieve effective draining of water in the above floor elements, regardless of the water permeability of the surface.

The object of the invention is therefore to significantly improve a floor element of the type mentioned, so that the mentioned disadvantages are overcome advantageously. Likewise, a composite formed with it should be proposed.

The object is achieved by a floor element with the features of claim 1 and by a composite with the features of one of the independent claims.

Accordingly, a floor element is proposed in which the upper side of the floor element is formed convex or convex toward the center.

By these measures, a new floor laying and laying element is created, which can not only be assembled very easily directly with appropriately designed further floor elements, but also may have any surface structure, and still has a very good drainage property for water. Also, by these measures in particular for laying in Outside areas created an automatic drainage effect for rainwater and the like.

In addition, the base element formed as a bottom plate can also be set with elongated profiles, panels and the like to form a composite. This results in an even greater variety of installation types, without having to sacrifice performance characteristics. The texture of the surface may change in shape, color and / or orientation from bottom plate to bottom plate. In addition, the shape of the bottom element itself may be varied, preferably rectangular and in particular square. The floor elements created in this way can easily be laid by laypersons themselves.

The convex shaped upper surface of the floor element ensures a safe drain of any occurring rain and / or splash water at any time. Since the top drops off from all sides towards the center, a quick drain is always ensured.

The floor elements presented here are very flexible and readily joined together to form a composite. In addition, a fixed mechanical connection between in each case two adjacent floor elements can be created in each case by at least two fastening elements or fastening means provided on each edge so that a multiplicity of different laying patterns is made possible. In particular, the floor panels can be laid very easily in an offset grid spacing from each other. The variety of installation types is also due to the fact that the nature of the surface in shape, color and / or orientation can change from bottom plate to bottom plate. In addition, the shape of the floor element itself be varied, preferably rectangular and in particular square. The floor elements created in this way can easily be laid by laypersons themselves.

According to the invention, a composite consisting of several assembled floor elements is also proposed, the composite consisting of floor elements of the same shape, in particular a square shape. In this case, the upper sides of the floor elements preferably have different surface structures, colors and / or orientation.

Further particularly advantageous embodiments of the invention emerge from the subclaims:

Thus, it is particularly advantageous if a distance or expansion gap remains when the detents of the floor element in the counter-locking points of an adjacent floor element. This provides additional flexibility when laying a composite consisting of floor elements. It also achieves an even better drainage of water and ventilation against moisture. This feature combination can also be regarded as an independent invention.

Preferably, the mutually spaced fasteners are arranged at a distance from each other or offset, which corresponds to a rational fraction of the edge length, in particular half the edge length. Thus, a clearly defined by the distance grid can be specified, which can then be easily adhered to when laying the floor elements, because it sets itself, so to speak, automatically.

In addition, and especially in this context, it is advantageous if the bottom element itself also has counter-locking points, wherein the bottom element is formed as a rectangular, in particular square, bottom plate with four edges, of which only two of the opposite edges each have at least two mutually spaced fasteners, and the other opposing edges each have only at least one counter-locking point. This creates an at least longitudinally symmetrical bottom element, which can be laid very variable.

The bottom element is preferably designed so that the detents are not visible in the assembled state.

In a further advantageous embodiment, the bottom element itself also counter-locking points, wherein the bottom element is formed as a rectangular, in particular square, bottom plate with four edges, and wherein each edge has at least two mutually spaced fasteners and at least one Gegenrastungsstelle. As a result, a fully symmetrical base plate is created, which can be installed both in the same direction as well as alternately in opposite directions or rotated by 90 degrees orientation. This results in very different laying patterns.

In this context, it is particularly advantageous if each fastening element has at least two protruding detents, in particular at least two nose-shaped or spring-shaped detents, which engage in the laying of the bottom element in there provided counter-locking points, in particular in nose-shaped or groove-shaped counter-locking points. This will Also allows a faster, especially designed as a tongue and groove connection, cohesion with the same or other floor elements.

Also, there are particular advantages if the top of the bottom element has a predeterminable surface structure, in particular a groove-like surface structure. Thus the composite not only receives a special visual impression, e.g. a design embossed by longitudinal or transverse grooves, but also a special functional property, such as e.g. an anti-slip effect etc ..

Regardless of or in connection therewith, the underside of the bottom element may be offset towards the middle or concave. This ensures that the designed as a bottom plate floor element rests safely and wobble on an uneven surface.

It is also advantageous if the latching elements are formed symmetrically in the bottom element, in order to engage in counter detents of a bottom element, which is designed as a symmetrically constructed profile element. This characteristic allows a mutual relocation and thus a special variance of the installation options.

There are advantages if the fasteners themselves have holes or holes for attachment of the bottom element on a substrate, a substrate and / or substructure. Even if a solid bond can already be produced by the mere engagement, the prefabricated holes or bores allow a fast and secure fixation of the bond to the respective base or substructure.

In this case, the bottom element is preferably designed so that the holes are not visible in the assembled state.

The functional as well as optical attractiveness of such a composite is in particular increased by the fact that it consists of bottom elements of the same shape, in particular a square shape, but that the top sides of the bottom elements have different surface structures and / or colors and / or orientation. In this context, it is of particular advantage if the respective mutually adjacent floor elements in an offset distance, in particular in the o.g. Distance or pitch, moved to each other and joined together. Because an offset laying of the floor elements results in a particularly appealing overall visual impression.

It can also be a composite consisting of a plurality of assembled floor elements in particular designed that it consists of the floor elements and mehren symmetrical profile elements. This results in an assembly of floor panels and profile elements or profile elements, which has advantages especially in terraced construction.

FIGS. 1a and 1b show a first example of a floor element 100 designed as a square base plate, in plan view of the top 110 and in the view of the bottom 120. The bottom plate 100 preferably consists of a weather-resistant and UV-protected composite material or a composite material Compound of wood chips, polypropylene and various additives. The wood chips are preferably from sustainable forestry and contain no waste wood. The formula is resistant to moisture and fungi, so that the bottom plate can be used in particular as a floor covering in outdoor use. The production takes place in injection molding machines or in accordance with procedures carried out accordingly.

The bottom plate 100 has a closed surface of, for example, 40 cm x 40 cm, which is committed and is exposed directly to the weather. The square bottom plate 100 thus has an edge length L of 40 cm. The top 110 or the Begehfläche is performed by about 1-2 mm convex (convex), so that, for example, rainwater can not remain on the surface, the surface can thus dry faster and can not form puddles. Due to the choice of material, the bottom element 100, in particular its upper side 110, has a deliberately wood-like appearance. Due to a deep groove structure on the surface results in improved slip resistance and dirt resistance, since the dirt in the Rillentäler less noticeable. The Rillenberge can be designed by roughening with steel brushes even wood-like and non-slip.

The groove structure of the upper side 110 shown here in FIG. 1 a has a transverse orientation, but it can also be diagonal or else designed as an imitation of wooden strips in a wide variety of arrangements or slightly diffuse orientations. It is even conceivable stone imitations, such. Slate, etc., as well as in general any kind of fantasy structure. It is also possible to arrange recesses in the top surface 110 or in the surface, e.g. Soil radiators or decorative elements such. To integrate ceramic plates or stainless steel sheets.

The bottom plate 100 is, for example, 38 mm high and has on each of its four edges 130 and sides respectively two fastening elements 140 and fastening means, which each have three protruding detents 141. Thus, each fastening element 140 is quasi an outstanding block or a plug-in element consisting of several grids 141. The fastening elements 140 are arranged on the respective side or edge 130 equidistant at a distance D. This preferably corresponds to half the length L of an edge 130, so here is 20 cm. This can be used when laying the Floor panels 110 are laid in a line or gaps with an offset of half a plate width, as shown in Figs. 5 and 6, respectively. Due to the predetermined distance D even laymen can perform the laying of the floor panels very easily and precisely. They are helped by the fact that the bottom plates 100 can be moved in offset to stop the fasteners 140 out and thus can be installed in the exact pitch.

The design of the detents 140 and locking elements is shown in more detail with reference to Figures 2a and 2b. The detents 141 have at their front edge respective slopes 142, which allow even with not exactly aligned bottom plate 100, a simple mating with the respective neighboring base plate (see also Fig. 3). In order to absorb or absorb any dimensional changes due to thermal expansion or swelling in the width of the base plate 100 and within the installed surface, a gap F is provided which automatically results when the base plates 100 engage. This so designed detent 141 facilitates the laying of the bottom plate 140 because of the automatically adjusting expansion joints F considerably.

Even with regard to a certain tolerance deviation, which may occur during the production of the floor panels (or even with aging), an optimal installation result is achieved by the construction: For the floor panels 100 can be in the composite to the joint width F larger, without affecting , in particular stresses on the laid surface. In addition, the detents 141 are not designed to be too deep and amount to only a few tenths of a millimeter, so that when larger or smaller the bottom plate 100, even with deviations within the manufacturing tolerance, only slight changes in the height of the bottom plate 100 in the edge region or transition region may result to the next bottom plate.

As shown in FIG. 1b, the bottom plate 100 in the substructure has a rib-shaped structure. For stiffening, the underside 120 is provided with cross-shaped ribs 121, which allow, even with a resting on only two longitudinal edges bottom plate 100, these high weight of e.g. 400 kg to load. The deflection is less than 2.5 mm. The spacing of the ribs 121 is selected so that the heel surface of the bottom plate 100 can not break even under punctiform loading (e.g., by a person of 100 kg in weight and stiletto heels). The underside 120 or rear side of the bottom plate is offset toward the middle or concave. Only the two outer rows of ribs 122 form the total thickness of 38 mm, i. have the full extent of the plate height. The inner rows of ribs are lowered or set inwards. As a result, only the outer rows of ribs 122 lie on the substrate, which leads to a smaller contact area and greatly reduces any unwanted absorption or "absorption" of moisture, especially in a moist surface. In addition, the bottom plate 100 can thereby rest well even with an uneven and slightly convex ground and thus be laid wobble-free.

Because of the special arrangement of the ribs 121 can be formed very easily by sawing the outer rib with the fasteners, a closed edge. This closed edge is also formed when the plates are mounted "on the gap", ie offset by half the plate width (see also Fig. 6).

Figures 2a and 2b show in more detail the pronounced at the edges of the bottom plate fasteners 141, which is formed in each case as a plug-type connecting element with three grids 141. Each detent 141 has at its end a slope 142 which can engage in a counter-locking. For this purpose, in particular, Fig. 2b shows a pronounced as a circumferential nose counter-detent 150, which cooperates with the respective detent 141 of the counter-plate. This is again shown in Fig. 3 exactly. There, the assembled state of two bottom plates is shown in cross-section, wherein the detent 141 engages the one bottom plate 100 in the nose-shaped counter-detent 150 'of the other bottom plate 100'. As can be seen with reference to FIG. 3 a, each fastening element 140 is formed by a transverse web and by three webs lying vertically, which represent the actual detents 141. At the transverse web still small vertical support or reinforcing webs are created, between which holes 145 or holes for mounting the bottom plate are set on a substrate.

4, the assembled state of a connection consisting of a bottom plate 100 and a profile element 200 is shown as a further embodiment in cross section, wherein the fastening element 140 and the detent of the bottom plate 100 engages in a nose-shaped fully symmetrical counter-detent 240 of the profile element 200. Thus, it will be appreciated that the floor panel 100 may also be used in combination with other floor elements, e.g. Profile elements 200, can be laid.

By way of example, a composite V1 or V2 of a plurality of base plates 100 is shown by way of example on the basis of FIGS. 5a and 5b in order to illustrate the possibilities of variation of the base plate. FIG. 5 a shows a top view of a first composite V 1 consisting of a plurality of square bottom plates 100, which have the same design, namely a groove-like top 110 with transverse or longitudinal grooves. By alternating rotation of the plates by 90 degrees, a checkerboard-like laying pattern is achieved.

5b shows in plan view a second composite V2 consisting of a plurality of square bottom plates 100, which have the same configuration, namely a fine-grained upper side 110 'with obliquely or diagonally extending grooves. Again, the plates can be rotated alternately, so that there is a certain pattern.

A laying pattern is shown with reference to FIG. 6, in which the plates are laid offset from one another. The figure shows in plan view a third composite V3 consisting of a plurality of square bottom plates 100, which have different configurations, namely a groove-like top 110 and a uniform and roughened without preferential direction top 110 'have, with adjacent floor panels to each other by a distance D, the half the edge length, are offset. This creates a visually particularly impressive pattern. FIGS. 5 and 6 illustrate that many more variants are possible.

The mutual engagement when laying the floor panels already creates a solid bond. For attachment to the respective subsurface bores are now still provided, which are preferably no longer visible in a closed composite. Therefore, the holes in the fastening elements or in the protruding detents, in particular in the transverse webs, laid.

Fig. 7 shows in cross-section a detent 140 with a prefabricated hole 145 therein or a bore for fixing the bottom plate on a base or substructure. The pre-drilled or injection-molded hole 145 is preferably slightly tapered so that a mounting bolt can be easily inserted.

FIG. 8 shows, in cross-section, a connection of two base plates 100 and 100 'and the attachment to a substructure 300. The hole or screw is perpendicular to the ground or ground.

FIG. 9 shows in cross-section a connection between a base plate 100 and a profile element 200 and the attachment to a base or substructure 300 '. This compound corresponds to the compound shown in Fig. 4. Here, the hole 145 or the screw extends obliquely to the ground in the direction of the bottom plate 100, so that during assembly, the profile element 200 can not be damaged by the screw. The outer dimension of the square plate 100 preferably corresponds to the width of three profile elements 200. Thus, the bottom plate 100 can also be installed within a surface of profile elements, where the joints run so that there is a harmonious overall picture.

As FIGS. 7 to 9 show, merely simple mounting screws are required for fastening the base plates 100 or the respectively formed composite V1, V2 or V3. When laying the one bottom plate is screwed and then the next bottom plate snapped into it and screwed again. By telescoping the floor panels Both the fasteners 140 and the screws are covered by the following base plate.

The further figures 10 -12 now show embodiments in which the bottom plate is suitable for laying with profile elements, wherein in each case a tongue and groove connection is made. These solutions can also be understood as embodiments of an independent invention.

10a firstly shows the view of a floor element configured as a square base plate 100N in a plan view of the top side 110N of the bottom plate, wherein this bottom plate 110N has a groove-shaped detent on each edge side as a fastening element 140N. The plate thus has laterally circumferential grooves140N.

Fig. 10b shows this square bottom plate 100N in the view of its underside 120N.

If you want to create in this bottom plate 100N with laterally encircling grooves a composite exclusively from such floor panels, so additional frictional elements between the floor panels are necessary for frictional installation. This is also shown with reference to FIG. 11, which reproduces in cross-section a connection of two such floor panels 100N and 100N 'produced by means of spring elements 400.

Preferably, the lower groove cheek also serves as a receptacle for the mounting or fastening screw. This screw is then no longer visible when laying the subsequent base plate. When laying the plates 100N and 100N 'are kept at a distance by the width of the spring elements 400, so that a compulsory expansion joint between gives the floor panels. However, this distancing is designed so that the expansion joint is securely adhered to during installation, but later in the event of possibly getting larger the floor panels, eg by swelling, this spring will compress without much resistance to ensure the function of the expansion joint.

A particular advantage of the bottom plate 100N revolving groove shown here, is the ease of combination with many other profile elements. This is also made clear with reference to FIGS. 12a and 12b. Here, Fig. 12a shows in cross section a connection between such a bottom plate 100N and a profile element 200, wherein the profile element has on one of its edges a spring-shaped or dowel-shaped expression, which engages in the groove-shaped detent of the bottom plate. Fig. 12b shows in cross section a connection between this bottom plate 100N and the profile element 200, wherein now the profile element on the opposite edge has a groove-shaped groove which is connected by means of spring elements 400 with groove-shaped detent of the bottom plate.

Here can be connected to the groove side -using the Federelementes- as well as with the spring side of the profile, on the bottom plate. This makes it easier to integrate areas of floor slabs into areas of profiles with the advantage of "invisible" fastening.

So that the profiles 200 can be used as a border, for example, the latching elements of the bottom plate 100N are designed so that the "groove side" of the profiles also engages to form the same expansion joint. The profile then only needs to be screwed visible. Also the bottom plate 100N shown here has a square shape. Of course, shapes such as rectangles, hexagons, diamonds or the like are also conceivable, which can then also be combined.
