plastic panel

The present invention relates to a plastic panel having a first main surface and a second main surface, wherein the plastic panel is formed as a multilayer laminate for the design of surfaces.

From EP 1 938 963 B2, a floor panel in the form of a rectangular plastic panel is known, which has a soft core made of PVC, on top of which there is a decorative sheet. At least two opposite edges are equipped with a lockable Nutfederprofil so that individual floor panels can be clicked together to form a flat floor covering.

Plastic panels, especially made of PVC, are becoming increasingly popular because they can be laid very easily, quickly and cleanly by laymen. Currently PVC panels are often laid in wood look.

It is an object of the present invention to provide a plastic panel, with which other optical effects can be achieved, in particular, a tile appearance should be achievable.

This object is achieved with the subject matter of claim 1. Advantageous embodiments and developments are the subject of the subclaims.

According to one aspect of the invention, a plastic panel is provided having a first major surface and a second major surface, wherein the plastic panel is formed as a multilayer laminate for forming surfaces. The plastic panel can in particular be particularly rectangular, ie, both the first main surface and the second Hauptoberfiäche are rectangles.

The plastic panel has a core with a first major surface and a second major surface and side surfaces, the core having locking elements on at least two opposing side surfaces. The first skin surface and the second major surface of the core are aligned parallel to each other and the side surfaces are typically oriented substantially perpendicular to the major surfaces. The locking elements serve to assemble individual plastic panels into a flat floor covering.

The plastic panel further has at least one first decorative layer arranged on the first main surface of the core and at least one second decorative layer arranged on the first decorative layer. The first decorative layer is exposed in the edge regions of the plastic panel on the first main surface of the plastic panel.

A plastic panel is understood here and below to mean a panel which, at least to a substantial extent, is made of plastic, for example of PVC. The plastic panel according to the invention is suitable for the design of surfaces. In particular, it can be used as a floor covering or for the design of walls. Thus, the plastic panel has the same scope as conventional tiles.

A laminate is understood here and below as a multi-layer structure, as it is known from floor coverings.

The two main surfaces of the panel are typically understood to mean the two opposite, largest-area surfaces, which may also be referred to as top and bottom.

The plastic panel has the advantage that it allows the appearance of a tile look. This is made possible, in particular, by the fact that the first decorative layer is exposed in edge regions of the plastic panel and thereby produces a joint optic. Since the second decorative layer is arranged on the first decorative layer, the first decorative layer jumps back relative to the second. Are several plastic panels joined together to a flat floor covering, so are the exposed areas of the first decorative layer visible as a recessed "joints" between the two-dimensional areas of the second decorative layer.

This makes it possible to produce a tile look with joints in a particularly simple manner, wherein the plastic panels are designed such that they can be easily moved by a layman. Laying individual elements with spacers in between and then grouting the laid panels with a grout are no longer necessary because the joints are already integral parts of the panels.

According to one embodiment, the first decorative layer has a first color and the second decorative layer has a second color, which is different from the first color. This contributes to the creation of tile-joint optics. Numerous different combinations of first color and second color are conceivable. For example, a light color can be selected for the first decorative layer and a dark color for the second decorative layer, so that the floor panels mimic bright joints and dark tiles or stones.

The plastic panel has the advantage that a large number of different optics can be achieved in a particularly simple manner, because the materials of the individual layers, in particular the decorative layers, can be used in a simple manner in a simple manner; moreover, the plastic panels can have virtually any desired format. In this way, at least all the optics known from tiles can be achieved.

According to one embodiment, the first decorative layer is exposed in two adjoining edge regions of the plastic panel and is completely covered by the second decorative layer in the other edge regions. Alternatively, the first decorative layer can also be exposed in all edge regions of the plastic panel.

These two embodiments differ in whether the "joints" disposed between two panels are each associated with only one of the two panels, or both, and often it will be easier to make transitions between the plastic panels invisible when the first decorative layer is only in two adjacent ones , ie, for example, exposed "over corner", edge regions of the plastic panel and is completely covered in the remaining edge regions of the second decorative layer. In this case The border between two plastic panels is not in the middle of a joint, but in the border between joint and tile.

According to one embodiment, the second decorative layer in the edge regions in which the first decorative layer is exposed, in cross-section rectangular edges.

According to this embodiment, a natural stone or stone look with sharp saw edges is imitated with the plastic panel. For this purpose, the second decorative layer is sharply cut back in its edge regions.

Alternatively, the second decorative layer may also have rounded edges in cross-section in those edge regions in which the first decorative layer is exposed. In this case, the appearance of the plastic panel corresponds to that of a classic ceramic tile.

According to one embodiment, at least one protective layer is arranged on the second decorative layer. The protective layer may in particular be a protection against wear. The protective layer is typically transparent.

On the second main surface of the core is typically arranged at least one Gegenzugschicht, which can also serve as a damping layer.

The plastic panel may have additional layers which may be disposed between or at boundaries to the already described layers. These layers may be formed for example as layers of an adhesive material or as layers with other functions.

The locking elements of the plastic panel may be formed in particular as elements of lockable tongue and groove joints. With the help of such tongue and groove joints the plastic panels, as it is already known from the field of wooden floors, laid in a particularly simple manner by a layman.

In the following the invention will be described in more detail with reference to figures. Figure 1 shows schematically a cross section through a bandage of plastic panels according to an embodiment of the invention;

Figure 2 shows schematically a cross section through a portion of a plastic panel according to a first variant of the invention;

Figure 3 shows schematically a cross section through a portion of a plastic panel according to a second variant of the invention and

FIG. 4 schematically shows a plan view of a dressing of a plurality of plastic panels according to an embodiment of the invention.

Figure 1 shows a bandage 1 of plastic panels 2, of which only two are shown in Figure 1. The plastic panels 2 each have a first Hauptoberfiäche 3 and a second Hauptoberfiäche 4, which are aligned substantially parallel, as well as perpendicular thereto arranged side surfaces 5, 6. The individual panels 2 are parallelepiped, i. their main surfaces 3, 4 are rectangular.

The panels 2 each have a core 7 of a relatively soft plastic, in particular PVC on. The core 7 is typically several millimeters thick and has on two opposite sides locking elements, which are designed here as a spring 10 and groove 11 and serve to connect individual panels 2 together. The core 7 has a first main surface 8 and a second main surface 9. On the Hauptober- fiächen 8, 9 more layers are arranged. On the first main surface 8, but not directly on the first main surface 8 in the embodiment shown in FIG. 1, a first decorative layer 12 is arranged. On the first decorative layer 12, a second decorative layer 13 and on this a protective layer 14 is arranged. The decorative layers 12, 13 and the protective layer 14 may be applied in particular as films or paints. Further layers 19 are arranged on the first main surface 8 and the second main surface 9 of the core. These layers 19 may, for example, be adhesive layers or, in particular on the second main surface 9, counter-tension layers.

At the first main surface 3 of the panels 2, the first decorative layer 12 is exposed in edge regions 15. In these areas, the second decorative layer 13 is cut back so that intermediate 17 areas between the second decorative layer 13 and the protective layer 14 arise when the plastic panels 2 are joined together to form a dressing 1. In the intermediate spaces 17, which have the width b and the depth a, the first decorative layer 12 is exposed. These areas give the impression of joints. To reinforce this impression, in particular the first decorative layer may have a different color than the second decorative layer.

If necessary, the regions of the second decorative layer 12 in the intermediate spaces 17 could also be provided with a protective layer.

FIG. 2 shows a cross section through an edge region 15 of the panel 2, showing only the core 7 and the layers arranged on its first main surface 8, but not the layers arranged on its second main surface 9. In this illustration, further layers 19 are not shown on the first major surface except for layers 12, 13 and 14.

In the embodiment shown in Figure 2, a stone look is to be achieved. Natural stoneware or slabs of porcelain stoneware are typically laid with sharp saw edges. To mimic this, the second decorative layer 13 is cut back at right angles together with the protective layer 14 arranged thereon so that the side surface 16 of these layers is at right angles to the first main surface 3 of the plastic panel 2.

In contrast, FIG. 3 shows a second variant of the plastic panel 2 in which the second decorative layer 13 and the protective layer 14 arranged thereon have been cut back in a rounded manner so that the side surface 16 of these layers is rounded in the edge area. With this embodiment, for example, the appearance of a classic ceramic tile can be imitated.

The cutting back of the second decorative layer 13 and optionally also of the protective layer 14, if already applied, can take place, for example, when the locking elements are cut into the layer forming the core 7. There are then no further process steps or tools required for this purpose.

In an embodiment, not shown here, the second decorative layer can be cut back obliquely or curved in profile. FIG. 4 shows a plan view of a bandage 1 of plastic panels 2 already laid. In this view, it can be seen that the first decorative layer 12 is exposed in a gap in the intermediate spaces 17 between the areas in which the second decorative layer 13 is visible. At the edge of the entire bandage 1, the locking elements of the core 7 are exposed, which are formed in the embodiment shown as a spring 10.

The "joints" formed by the exposed first decorative layer 12 have in the embodiment shown all around the same width.

In the lower area of Figure 4, a further plastic panel 2 is shown that is just to be connected to panels 2 of the dressing 1. For this purpose, the plastic panel 2 is pushed in the direction of the arrow 18 to the dressing 1 and connected by introducing the spring 10 in the not visible here groove of the adjacent plastic panel 2 with this, wherein the spring 10 is clicked into the groove and thus locked therein.

The plastic panels 2 are therefore particularly easy to lay by a layman, a tile look without additional assembly steps and in particular without handling a grout can be achieved, which len the scope of Kunststoffpanee- len, especially PVC panels, significantly expanded for surface design. The plastic panels 2 can be easily produced in a variety of formats.
