Description

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

From the EP 1 938 963 B2 is a Bodenpaneel in the form of a rectangular plastic plate is known, which has a soft core of PVC, on top of which is a decorative film. 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 further developments are the subject of the dependent claims.

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. In this case, the plastic panel may be formed in particular rectangular, i. both the first major surface and the second major surface 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. In this case, the first skin surface and the second main surface of the core are aligned parallel to each other and the side surfaces are typically aligned substantially perpendicular to the main 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.

Under the two main surfaces of the panel are typically understood to mean the two opposite, areally largest surfaces, which can also be referred to as the 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 optics. Since the second decorative layer is arranged on the first decorative layer, the first decorative layer jumps back relative to the second. If several plastic panels are joined together to form a flat floor covering, then the exposed areas of the first decorative layer are visible as 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 many different optics can be achieved in a particularly simple manner, because the materials of the individual layers, in particular the decorative layers, are easily used in a variety of ways. In addition, 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" arranged between two panels are each associated with only one of the two panels or both. Often, it will be easier to make transitions between the plastic panels invisible when the first decorative layer is in only two adjoining, i. for example, "over corner" lying edge portions of the plastic panel is exposed and is completely covered in the remaining edge areas 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 in particular be designed as elements of lockable tongue and groove connections. 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.

• 2 shows schematically a cross section through a portion of a plastic panel according to a first variant of the invention;
• 3 schematically shows a cross section through a portion of a plastic panel according to a second variant of the invention and
• 4 schematically shows a plan view of a dressing of several plastic panels according to an embodiment of the invention.

1 shows a bandage 1 made of plastic panels 2 of which in 1 only two are shown. The plastic panels 2 each have a first main surface 3 and a second main surface 4 on, which are aligned substantially parallel, as well as vertically arranged side surfaces 5 . 6 , The individual panels 2 are cuboidal, ie their main surfaces 3 . 4 are rectangular.

The panels 2 each have a core 7 made of a relatively soft plastic, especially PVC on. The core 7 is typically several millimeters thick and has on two opposite sides locking elements, here as a spring 10 and groove 11 are formed and for connecting individual panels 2 serve each other. The core 7 has a first main surface 8th and a second main surface 9 on. On the main surfaces 8th . 9 Several more layers are arranged. On the first main surface 8th but in the in 1 embodiment not directly on the first main surface 8th , is a first decorative layer 12 arranged. On the first decorative layer 12 is a second decorative layer 13 and on this a protective layer 14 arranged. The decorative layers 12 . 13 as well as the protective layer 14 can be applied in particular as films or paints. Further layers 19 are on the first main surface 8th and the second main surface 9 arranged at the core. These layers 19 For example, adhesive layers or - especially on the second major surface 9 - be counter-layers.

At the first main surface 3 the panels 2 is located in peripheral areas 15 the first decorative layer 12 free. In these areas is the second decorative layer 13 cut back, leaving gaps 17 between areas of the second decorative layer 13 and the protective layer 14 arise when the plastic panels 2 to a bandage 1 are joined together. In the intervals 17 that the width b and the depth a have, lies the first decorative layer 12 free. 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 areas of the second decorative layer could also be used 12 in the interstices 17 also be provided with a protective layer.

2 shows a cross section through a border area 15 of the panel 2 where only the core 7 and those on his first main surface 8th arranged layers are shown, but not on its second major surface 9 arranged layers. In this illustration are also other layers 19 on the first main surface, apart from the layers 12 . 13 and 14 , Not shown.

At the in 2 embodiment shown stone optics should be achieved. Natural stoneware or slabs of porcelain stoneware are typically laid with sharp saw edges. To imitate this is the second decorative layer 13 together with the protective layer on top 14 cut back at right angles, leaving the side surface 16 these layers at right angles to the first main surface 3 of the plastic panel 2 stands.

3 shows in contrast to a second variant of the plastic panel 2 in which the second decorative layer 13 as well as the protective layer arranged thereon 14 rounded back so that the side surface 16 these layers in the edge area is rounded. 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 the protective layer 14 If this is already applied, for example, if the locking elements in the core 7 forming layer are cut. 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.

4 shows a plan view of a bandage 1 already installed plastic panels 2 , In this view, it can be seen that in the interstices 17 between the areas where the second decorative layer 13 is visible, the first decorative layer 12 exposed like a genie. At the edge of the entire bandage 1 are the locking elements of the core 7 free, which in the embodiment shown as a spring 10 are formed.

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

In the lower part of 4 is another plastic panel 2 shown that straight with panels 2 of the association 1 to be connected. This is the plastic panel 2 in the direction of the arrow 18 to the bandage 1 pushed and by introducing the spring 10 in the not visible here groove of the adjacent plastic panel 2 connected to this, the spring 10 is clicked into the groove and thus locked in it.

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