Description

Technical area

[0001] The present invention relates to a wall, furniture or floor panel. State of the art

[0002] Wall, furniture, and floor tiles are made from a variety of materials, such as stone, ceramic, wood, fiberboard, cork, linoleum, or plastic. They are bonded to a substrate via adhesive, for example, and serve functional and aesthetic purposes, such as decorative, easy-to-clean surfaces.

[0003] DE 20 2021 103 942 U1 discloses a wall, furniture, or floor panel made of a mold-processable epoxy or polyester resin. This wall, furniture, or floor panel allows for a variety of customizable surfaces, including a texture imprinted on the contact surface of the mold and any desired color. Due to the material thickness of 3 mm, the plastic consumption is still relatively high. Description of the invention

[0004] Based on the above-mentioned prior art, it is the object of the present invention to provide a wall, furniture or floor panel which can be produced more cost-effectively while offering a comparably wide range of design options.

[0005] The solution according to the invention consists, in particular, in providing a wall, furniture, or floor panel with a panel-shaped main body. The panel-shaped main body can be connected via an underside to a wall or floor in a room of a building or to a piece of furniture. The upper side of the panel-shaped main body faces the room as a usable surface.

[0006] According to the invention, the wall, furniture or floor panel is characterized in that the main body is formed from a plate-shaped carrier material on the underside and a natural resin or synthetic resin layer, in particular a polyurethane layer or polyurea layer, which can be processed in a mold, on the upper side.

[0007] In practice, the polyurethane layer is preferably placed in a mold, and then the sheet-like substrate is inserted. The polyurethane, which can be processed in a mold, poured, spread, or sprayed, allows the production of various shapes, sizes, and contours of wall, furniture, or floor panels.

[0008] The carrier material allows for a reduction in the thickness of the polyurethane layer, thus resulting in significant material and cost savings. Furthermore, the carrier material allows specific mechanical properties to be transferred to the wall, furniture, or floor panel.

[0009] The plate-shaped support material is preferably made of rubber. Alternative support materials include wood or metal. The advantages of rubber as a support material lie in its elastic properties, its shock-absorbing effect, and its good sound insulation. A particularly preferred application is for floor panels, which are given shock-absorbing properties. The floor panels can be used as fitness or yoga mats, or as impact protection mats on playground equipment or bouldering walls.

[0010] The rubber sheet is preferably made of rubber granulate, particularly preferably made of recycled material. In general, the rubber granulate sheet made of recycled material contributes to sustainability and reduces environmental impact because it is made from reused materials. In addition to high sustainability and environmental friendliness, it also results in a cost-effective raw material base. For example, it is conceivable that the rubber granulate could be made from granules obtained from used tires.

[0011] According to an advantageous development of the invention, the plate-shaped carrier material has a thickness of at least 2 mm and / or a maximum of 30 mm. The plate-shaped carrier material is particularly preferably between 7 and 9 mm thick. A plate thickness of 8 mm has proven to be particularly advantageous. The defined plate thicknesses achieve an optimal balance between stability and flexibility of the wall, furniture, or floor panel. The dimensions are also suitable for standardized processing and optimized material utilization.

[0012] In an advantageous development of the invention, the natural resin layer or synthetic resin layer, in particular the polyurethane layer, has a thickness of at least 0.5 mm and / or a maximum of 1.5 mm, preferably a maximum of 1 mm. This correspondingly defined thickness ensures a robust and durable surface with sufficient surface protection while simultaneously being material- and cost-efficient. If the thickness is a maximum of 1 mm, the material consumption is only approximately 1 kg of polyurethane per square meter. This makes the wall, furniture, or floor panels according to the invention extremely lightweight and cost-effective, yet still exhibit outstanding strength and durability.

[0013] According to an advantageous development of the invention, a fabric layer is arranged in the main body. In particular, the fabric layer is arranged in the natural resin layer or synthetic resin layer. The fabric layer reinforces the structure, which allows a further reduction in the layer thickness of the natural resin layer or synthetic resin layer. The fabric layer ensures better dimensional stability and thus strengthens the structure of the wall, furniture, or floor panel. In addition, the tensile strength of the wall, furniture, or floor panel is increased. This also reduces the risk of cracks or breaks in the wall, furniture, or floor panel. The fabric layer is particularly preferably made of polyester or glass fibers.

[0014] Furthermore, the fabric layer is preferably designed as a mesh or grid structure, particularly preferably with a mesh size of 2 mm to 4 mm. The mesh or grid structure of the fabric layer ensures even distribution of the load and prevents deformation of the wall, furniture, or floor panel. The mesh size is the distance between two adjacent intersection points of the fabric.

[0015] According to an advantageous development of the invention, the upper side is provided with a three-dimensional structure. The three-dimensional structure can be embossed into the upper side of the wall, furniture, or floor panel using a complementary three-dimensional structure of the mold. The three-dimensional structure enables a realistic reproduction of natural materials. This results in increased visual value. For example, it is possible for the structure of the upper side to visually exhibit a stone or wood structure. This enables the use of the wall, furniture, or floor panel as an alternative to real natural materials. This results in a wall, furniture, or floor panel with a natural appearance and, at the same time, positive functional properties, such as elastic or shock-absorbing properties.

[0016] According to an advantageous development of this embodiment, the upper side is coated with a layer of lacquer containing colored particles. This has the particular advantage of emphasizing the unevenness of the structure on the upper side, i.e., the visible side.

[0017] This allows for even clearer and more visually appealing natural structures to be created.

[0018] The ability to shape the structure with a complementary form simplifies production and ensures consistent quality of the wall, furniture or floor panel.

[0019] According to an advantageous development of the invention, the natural resin layer or synthetic resin layer is formed directly on the plate-shaped carrier material, in particular without an intermediate layer or adhesion promoter. This results in a particularly simple manufacturing process, since the direct bond without an additional intermediate layer or adhesion promoter reduces manufacturing complexity. Short description of the drawings

[0020] The various and exemplary features described above can be combined with one another according to the invention, provided this is technically reasonable and suitable. Further features, advantages, and embodiments of the invention will become apparent from the following description of exemplary embodiments and from the figures.

[0021] The figures used to explain the embodiments show: Fig. 1 a section and a view of a wall, furniture or floor panel; Fig. 2 a section and a view of a floor plate arranged on the ground; and Fig. 3 a mould with a structure and a wall, furniture or floor panel manufactured in the mould. Ways to implement the invention

[0022] Fig. Figure 1 shows a section through a rectangular wall, furniture or floor panel 100 suitable for attachment to a wall or floor 140 of a room in a building or to a piece of furniture.

[0023] The shape and size of the wall, furniture, or floor panel 100 are extremely variable. These can be produced in small pieces or in large areas in any shape. Fig. The wall, furniture or floor panel 100 shown in Figure 1 has a main body 102 which is formed from a plate-shaped carrier material 103 and, for example, from a natural resin layer or synthetic resin layer 105 made of polyurethane.

[0024] As in Fig. As shown in Figure 2, the main body 102 has a top side 110 facing the room and a bottom side 120 connectable to the floor 140. The connection to the floor 120 is preferably made by gluing, for example with a PU adhesive or a PS adhesive. Fig. 2 it is also evident that a fabric layer 104 is embedded in the main body 102, in particular in the polyurethane layer 105.

[0025] This fabric layer 104 can preferably have a mesh or grid structure with a mesh size of approximately 2 mm to 4 mm. The fabric layer 104 can preferably be formed from glass fibers, which can be coated with polyurethane for better bonding. The mesh size can then be, for example, 3 mm to 4 mm.

[0026] When polyurethane is used as a material for wall, furniture, or floor panels, its Shore A hardness is between 50 and 90, preferably approximately 76 (according to DIN ISO DE 7619-1). Polyurethane also exhibits particularly excellent fire protection properties, achieving fire protection classes Bfl s1 and Cfl s1.

[0027] The Fig. The base plate 100 shown in Figure 2 further comprises a lacquer layer 106, which is preferably provided with color particles. In particular, the upper side 110 of the plate-shaped main body 102, i.e., the polyurethane layer 105 on the upper side 110, is coated with the lacquer layer 106.

[0028] This lacquer layer 106 serves to Fig. 3 to emphasize the recognizable 3-dimensional structure 112.

[0029] In Fig.3 shows an upwardly open mold 130, the bottom of which has a complementarily shaped structure 132. In particular, the mold 130 has a 3-dimensional structure 132. The 3-dimensional structure 132 can, for example, have a stone or wood structure, in particular also a flamed wood structure. When the polyurethane is poured, injected, or generally inserted into the mold 130, the upper side 110 of the wall, furniture, or floor panel 100 formed after curing takes on the structure 112 complementary to the structure 132 of the mold 130.

[0030] The plate-shaped carrier material 103 is arranged on the polyurethane layer 105 and bonds to the polyurethane layer 105 after baking and curing of the polyurethane, preferably at 60°. The plate-shaped carrier material 103 has a smooth horizontal surface on its underside 120.

[0031] After removal from the mold 130, the wall, furniture, or floor panel 100 thus has a smooth underside 120 for a flat connection to the wall or floor 140 of a room. The top side 110, on the other hand, has the three-dimensional structure 112, thus achieving a particularly unique visual appearance. Furthermore, the irregular structure 112 also offers excellent acoustic insulation properties.

[0032] Preferably, the wall, furniture or floor panel 100 is cut to size after demolding from the mold 130 and provided with the lacquer layer 106 on the upper side 110.

[0033] The plate-shaped carrier material 103 not only saves material for the polyurethane layer 105, but also exhibits different properties depending on the material. Preferably, the plate-shaped carrier material 103 is made of a rubber material, for example. The plate-shaped carrier material is thus designed as a rubber plate, so that the wall, furniture, or floor panel 100 also exhibits the flexible material properties of rubber.

[0034] The wall, furniture or floor panels 100 according to the invention are suitable and designed for a long service life and can also be completely recycled after use.

[0035] It should be noted that the features of the invention described with reference to individual embodiments or variants, such as the type and design of the individual components as well as their precise dimensions and spatial arrangement, may also be present in other embodiments, unless otherwise stated or technically prohibited. Furthermore, such features of individual embodiments described in combination do not necessarily always have to be implemented in a given embodiment.
