Description

[0001] The invention relates to a plate element, in particular for integration into a vehicle or a piece of furniture, a piece of furniture and a vehicle with such a plate element, and a method for processing a plate element.

[0002] Conventional components, particularly in furniture and / or vehicle interior fittings, typically use so-called cup connectors with screws to fasten two or more panel elements together. However, this type of fastening is material- and time-consuming and, moreover, not watertight.

[0003] The invention therefore aims to provide an improved panel element, an improved piece of furniture and vehicle, as well as an improved method for processing a panel element.

[0004] This problem is solved by the subject matter of the independent claims. Advantageous embodiments are specified in the dependent claims and the description.

[0005] According to a first aspect of the present invention, a panel element is provided. The panel element is particularly suitable for integration into a vehicle and / or a piece of furniture. In particular, the panel element forms part of a piece of furniture, and more specifically a wet cell, which is integrated into a vehicle.

[0006] Three different embodiments of a plate element are described below, which can be combined both singly and in multiple ways. In particular, the present inventions relate to three different types of cutouts and, in particular, their cross-sections. First, a cross-section that is essentially triangular is described, then a cross-section that is essentially trapezoidal, and finally a cross-section that is essentially rectangular, one or more of which can be provided in a plate element, both of the same and of different types.

[0007] In particular, according to a first embodiment, a plate element is specified, comprising a first cover layer, a second cover layer and an inner core arranged between the two cover layers, wherein the plate element comprises a first surface section, a second surface section and a second cutout arranged between them, wherein the first cover layer and the inner core are not present in the second cutout, wherein the plate element is designed to be flexible so that it can be deformed from a first state in which the first surface section is substantially parallel to the second surface section, into a second state in which the first surface section is arranged at an angle to the second surface section, wherein in the second, angled state the second cover layer faces the inside of the angle and wherein the plate element is permanently fixed in the second state.

[0008] A second embodiment also provides a plate element comprising a first cover layer, a second cover layer, and a core arranged between the two cover layers, wherein the plate element comprises a first surface section, a second surface section, and a second cutout arranged between them, wherein the first cover layer and the inner core are not present in the second cutout, wherein the plate element is designed to be flexible so that it can be deformed from a first state in which the first surface section is substantially parallel to the second surface section to a second state in which the first surface section is arranged at an angle to the second surface section, wherein the second cutout has a substantially trapezoidal cross-section in the first state.wherein in the second state the second cover layer faces the outside of the angle and wherein the plate element is permanently attached in the second state.

[0009] Likewise, according to a third embodiment, a plate element is provided comprising a first cover layer, a second cover layer and a core arranged between the two cover layers, wherein the plate element comprises a first surface section, a second surface section and a second cutout arranged between them, wherein the first cover layer and the inner core are not present in the second cutout, wherein the plate element is designed to be flexible so that it can be deformed from a first state in which the first surface section is substantially parallel to the second surface section to a second state in which the first surface section is arranged at an angle to the second surface section, wherein the third cutout has a substantially rectangular cross-section in the first state.wherein in the second state the second cover layer faces the outside of the angle and wherein the plate element is permanently attached in the second state.

[0010] It is understood that the numbering of the sections is arbitrary and initially intended only to represent a conceptual distinction. The types and, in particular, the cross-sections will be explained in detail later, beginning with a description of various designs of the plate element and, in particular, their structure, which can apply to all embodiments.

[0011] The panel element can also be referred to as a panel, wall element, wall, surface, and / or surface element and is constructed in a plate-like and / or planar form, with a greater length and width than height or thickness. The panel element comprises a core, as well as a first and a second facing layer, which are arranged on opposite sides of the core. A foil layer may also be applied to each facing layer. The core, the facing layer, and optionally the foil layer are themselves plate-like and / or planar and are arranged on top of or against each other. The thicknesses of the core, the facing layer, and the foil layer can differ from one another. In other words, the panel element is designed as a multi-layered panel element, which can also be described as a sandwich panel or sandwich construction.In particular, the plate element is cuboid-shaped in the first, undeformed state and is deformed into a different, especially angled, shape in the second, deformed state, as will be explained later.

[0012] In particular, the plate element has a central, inner core, wherein on each side of the core, in particular on each surface side along a principal extension plane, i.e. in particular along the length and width, a cover layer is first arranged and on top of this an outer film layer is optionally arranged.

[0013] The core preferably comprises hollow areas, which are particularly cell-shaped. These cell-like hollow areas are arranged repeatingly, especially along the main plane of extension of the panel element. The hollow areas can be bounded by strut elements, for example in the form of side walls. This results in a honeycomb structure. The panel element is therefore designed as a sandwich panel with a honeycomb core, whereby the honeycombs do not necessarily have to be hexagonal. Rather, it is possible for a wide variety of geometries to be formed for the cell area along a plane running parallel to the main plane of extension. Polygonal, e.g., hexagonal, rectangular or rhomboid, circular or elliptical cross-sections are possible. In particular, the core can be open-celled, especially on the side facing the respective face sheet.Alternatively, the core can also be made of a foamed material, in particular a foamed plastic such as Styrofoam or foam.

[0014] The surface layer is thinner than the core and is essentially solid. The optional foil layer is also thinner than the surface layer and is likewise solid. The panel element can therefore be composed of three or five layers.

[0015] In particular, all elements of the panel element, i.e., the core, the first and second cover layers, and optionally the first and second film layers, are made of one or more plastics, in particular one or more recyclable and / or reusable plastics, and further, in particular, one or more thermoplastic plastics, or at least comprise them. Additionally or alternatively, the elements of the panel element may comprise one or more other materials, in particular recyclable and / or reusable materials, that are not plastics, such as cork and / or wood. In particular, individual or all elements of the panel element are made of polypropylene and / or comprise polypropylene. Alternatively or additionally, individual or all elements of the panel element are made of polyethylene and / or comprise polyethylene.The plate element is preferably hydrophobic, waterproof and / or rot-resistant.

[0016] The thickness, height, or strength of the panel element is, for example, between 10 mm and 30 mm, particularly between 12 mm and 20 mm. The surface weight of the panel element is, for example, between 100 g / m². 2 and 10000 g / m² 2 , especially between 1,000 g / m² 2 and 8,000 g / m² 2 , especially between 700 g / m² 2 and 5,000 g / m² 2 .

[0017] In the panel element, particularly along its main plane of extension, at least one, and in particular several, cutouts are provided on one side, which divides the surface into a first section and a second section, or several surface sections. Within this cutout, the top layer, and optionally the foil layer arranged on the top layer, as well as the core, are absent on one side. In other words, only the opposite, second top layer and, if applicable, the foil layer arranged on it exist along the cutout. The cutout has a width that essentially corresponds to the width of the panel element.

[0018] The cutout(s) can be provided from the outset, for example, because the cutout was already incorporated during the production process of the panel element, or it can be added subsequently, in particular by removing the top layer, including any optional foil layer, and the core down to the opposite top layer in the area where the respective cutout is intended for the respective function. This can be done in particular by removal, especially mechanical removal, such as by a machining process like milling.

[0019] Due to the specific cutout, the panel element can be flexible, particularly in and around the area of ​​the cutout, especially since the first surface layer and the core are not present in this area, resulting in a material weakness between the surface sections. The cutout allows the panel element to be transformed from its essentially cuboid shape or flat state, which can also be described as the initial or undeformed state, into a second, deformed state. This is achieved, in particular, by moving or tilting the first surface section towards the second surface section, creating an angle between them. This can be done manually by one or more workers or by a robot.

[0020] Furthermore, a connecting element may be provided, which has an outer shape corresponding to the cutout and is designed to be positioned within the cutout. The cutout is specifically designed to accommodate the connecting element. The connecting element may be, in particular, a profile or profile rail. For example, the connecting element may be made of a metallic material, such as aluminum. Alternatively, the connecting element may also be made of a plastic, in particular a recyclable plastic and / or recyclable plastics, especially polypropylene and / or polyethylene. The connecting element and its properties will be explained in more detail below.

[0021] The connecting element and / or the cutout can be dimensioned and designed in such a way that the connecting element can be received in the cutout in the second state, particularly predominantly or substantially completely. In particular, the connecting element and / or the cutout is dimensioned and designed in such a way that it can also be received in the cutout in the first state, particularly predominantly or substantially completely.

[0022] In this process, either the plate element can first be transferred from the first, undeformed state to the second, deformed state and then the connecting element can be arranged in the cutout, or vice versa, i.e., the connecting element can first be arranged in the cutout and then the plate element can be transferred from the first, undeformed state to the second, deformed state.

[0023] Furthermore, an adhesive surface may be provided, which is arranged at least partially on the cutout and / or the connecting element, and which permanently fastens the component in the second state.

[0024] In particular, the adhesive surface is provided between the cutout and the connecting element in such a way that it connects or fastens the connecting element and the cutout and thus the plate element in the second state in a materially bonded and / or form-fitting manner, in particular in a permanent manner, and furthermore in a manner that is not detachable without destruction.

[0025] The adhesive material forming the bonding surface can be a one- or multi-component adhesive, particularly a two-component adhesive. The adhesive material can be, for example, polymer- and / or acrylate-based. Specifically, it is an adhesive based on a silane-modified polymer that is free of solvents and / or isocyanates.

[0026] The adhesive surface can be applied first to the cutout and / or to the connecting element, and then the connecting element can be placed in the cutout, or vice versa.

[0027] In particular, the cutout, the first surface section, the second surface section, and / or the connecting element were subjected to plasma treatment before the adhesive surface was applied, especially immediately before the adhesive surface was applied. Furthermore, no further treatment was carried out on the cutout after the cutout was applied and / or before the adhesive surface was applied.

[0028] Plasma treatment, as used here, involves exposing and / or applying plasma to the cutout, the first surface section, the second surface section, and / or the connecting element. Plasma is a mixture of particles that includes, for example, ions, free electrons, and / or neutral atoms or molecules. This can be done with a suitable plasma source and / or a plasma emitter. In particular, the cutout, the first surface section, the second surface section, and / or the connecting element can be treated with a low-pressure plasma.

[0029] The plasma treatment serves in particular to clean and / or remove particles or constituents that could prevent or impair the arrangement of the adhesive surface.

[0030] In particular, with the exception of the adhesive surface at the cutout, the first surface section, the second surface section and / or the connecting element, no further material is applied.

[0031] In this context, material application comprises the addition of a material. Specifically, no primer and / or base coat was added to the cutout, the first surface section, the second surface section, and / or the connecting element. Furthermore, and in particular, with the exception of the previously described optional plasma treatment, no further pretreatment with substances and / or reactants, and especially not with solvents, is carried out.

[0032] After applying the adhesive, arranging the connecting element in the cutout, and deforming the plate element into the second state, in whatever order, the plate element can be subjected to the pressure necessary for the adhesive material and / or held in the second state, in particular until the adhesive material has cured.

[0033] The adhesive surface is specifically designed to create a watertight seal between the cutout and the connecting element. In particular, the adhesive surface provides a watertight seal for the entire component in the area of ​​the cutout.

[0034] In this context, "waterproof" means that the adhesive surface is arranged and designed in such a way that no water can penetrate or pass through the cutout and the connecting element, particularly into or through the core. For example, "waterproof" means that penetration is prevented up to a water column of at least 500 mm, 750 mm, 1000 mm, 1500 mm, 2000 mm, 3000 mm, 5000 mm, 10000 mm, 20000 mm, or 50000 mm.

[0035] The first section can, in its first state, have a substantially triangular cross-section and in particular correspond to an isosceles, especially acute-angled, triangle, wherein in particular the angle at the apex of the triangle is less than 20°, in particular between 20° and 10°.

[0036] The trapezoidal cross-section of the second cutout can in particular correspond to an isosceles trapezoid.

[0037] The rectangular cross-section of the third cutout can, in particular, correspond to a square.

[0038] The solution according to the invention makes it possible to provide a particularly watertight design of a plate element with virtually any shape from just a single plate element. In particular, the solution according to the invention eliminates the need for two or more different plate elements and especially for cup connectors or screws. This results in a particularly advantageous and simultaneously reliable design of a plate element that can have multiple angles, corners and / or edges, thus enabling virtually any shape.

[0039] According to a further aspect, a piece of furniture is specified that comprises at least one or more panel elements according to the embodiments described above. The piece of furniture can, in particular, be part of a wet room, especially a shower tray. The invention makes it possible to produce several wall or floor surfaces from a single panel element. It is particularly advantageous that the edges, i.e., the transitions between the wall or floor surfaces, are designed to be watertight. In particular, the invention makes it possible to design at least one top layer to be continuous over one or more edges / angles. Therefore, the piece of furniture is preferably part of a wet room, especially a shower cubicle. The piece of furniture as a wet room preferably also includes the shower tray.

[0040] According to further training, the piece of furniture can include at least one structural element which has a higher strength than the one or more panel elements, wherein the structural element is arranged in the second state and supports at least along the first surface section and / or the second surface section.

[0041] The structural element can be, in particular, a part of a vehicle or be formed from one, especially a body element of a vehicle, such as a wheel arch. The structural element can serve to enable the installation of the piece of furniture in a vehicle in such a way that the (weight) forces are supported at suitable points on the vehicle frame or chassis.

[0042] According to another aspect, a vehicle is specified, comprising a panel element and / or a piece of furniture according to the embodiments described above.

[0043] According to a further aspect, a method for processing a panel element, in particular for integration into a vehicle or piece of furniture, is described. The method comprises the steps of providing a panel element according to a previously described embodiment and deforming the panel element from the first state to the second state.

[0044] According to a further aspect, a plate element is specified, wherein the plate element has been machined according to a previously described embodiment.

[0045] The invention will now be explained in more detail with reference to exemplary embodiments and the accompanying drawings. Identical or corresponding parts are identified in the drawings by the same reference numerals.

[0046] The drawings show: Fig. 1 a schematic side view of a plate element in a first state according to embodiments of the invention; Fig. 2 a schematic side view of a plate element in a first state according to further embodiments of the invention; Fig. 3 a schematic side view of a plate element in a first state according to further embodiments of the invention; Fig. 4 a schematic side view of a plate element in a second state Fig. 1; Fig. 5 a schematic side view of a plate element in a second state Fig. 2; Fig. 6 a schematic side view of a plate element in a second state Fig. 3; Fig. 7 a perspective top view of a plate element in a second state Fig. 5; Fig. 8 a perspective top view of a plate element in a second state from Fig. 6; Fig. 9 a perspective bottom view of a piece of furniture made from a panel element made of Fig. 6.

[0047] In the figures, identical or similar elements are designated with the same reference symbols. Three different embodiments are explained below, the individual features of which can, of course, be combined with one another.

[0048] Fig. Figure 1 shows a schematic side view of a plate element 100 in a first state according to embodiments of the invention.

[0049] The plate element 100 comprises a core 110, a cover layer 121, 122 on each side of the core 110, and a foil layer 131, 132 arranged on the respective cover layer 121, 122. The core 110 has the greatest extent along its thickness, the respective cover layers 121, 122 have a smaller extent along their thickness than the core and are essentially the same thickness, and the foil layers 131, 132 have an even smaller extent along their thickness and are also essentially the same thickness.

[0050] In the plate element 100, a first cutout 151 is provided, which divides the plate element 100 into a first surface section 101 and a second surface section 102. In this first cutout 151, the first cover layer 121, the first foil layer 131 arranged on it, and the core 110 are removed on one side up to the opposite second cover layer 122, so that only the second cover layer 122 and the second foil layer arranged on it remain in the cutout 150.

[0051] The first section 151 is shown here as an example with a triangular cross-section comprising a first lateral face, a second lateral face, and an opening, wherein the first lateral face and the second lateral face are arranged at the same angle to the opening and thus span or form an isosceles triangle, which is axially symmetrical about a vertical axis, with the base lying in the opening. In this example, Fig. In the state shown in Figure 1, the first surface section 101 is essentially parallel to the second surface section 102, however, due to the cutout 150, the two surface sections 101 and 102 are flexible or deformable relative to each other, in particular along the direction indicated by the arrow, as will be explained in connection with the further figures.

[0052] Fig. Figure 2 shows a schematic side view of a plate element 100 in a first state according to further embodiments of the invention.

[0053] The plate element 100 is assigned differently to Fig. In addition to the first cutout 151, which has the cross-section of an isosceles triangle, a second cutout 152 is shown, which has a trapezoidal cross-section, in particular, as shown here, that of an isosceles trapezoid. In this example, the trapezoid has a base on an end face opposite the opening and thus on the second cover layer 122. The corners are rounded. Here, too, the arrows indicate a direction of deformation, as will be explained in connection with the further figures.

[0054] Fig. Figure 3 shows a schematic side view of a plate element 100 in a first state according to further embodiments of the invention.

[0055] The plate element 100 is assigned differently to Fig. 1 and Fig. 2 In addition to the first cutout 151, which here has a rectangular, essentially square cross-section, a second cutout 152, which likewise has a rectangular, essentially square cross-section, and a third cutout 153, which has a trapezoidal cross-section, in particular, as shown here, that of an isosceles trapezoid in accordance with the second cutout according to Fig. 2. The first cutout 151 and / or the second cutout can also have a trapezoidal cross-section, which, however, can in particular be an asymmetrical or non-isosceles trapezoid, wherein the first side face is substantially at a right angle to the end face and the second side face is at an angle between 90° and 100° to the end face. In contrast to the third cutout, the first cutout 151 and the second cutout 152 are not located on the side of the first cover layer 121, but on the opposite, second side of the second cover layer 122, whereby the second cover layer 122 and the core 110 are not present up to the opposite first cover layer 121. Here, too, the arrows indicate a direction of deformation, as will be explained in connection with the further figures.

[0056] Fig. Figure 4 shows a schematic side view of a plate element 100 in a second state. Fig. 1.

[0057] The first surface section 101 and the second surface section 102 were moved towards each other and thus deformed, so that the two surface sections 101 and 102 form a first angle A1 with each other, which is shown here as essentially 90°. This deformation transformed the first triangular cutout 151 from an acute to an obtuse triangle. As a result, the second cover layer 122 is positioned on the inside of the first angle A1 and faces it. In this form, or second state, the plate element 100 can then be permanently fixed, or already is. This can be achieved, in particular, by a connecting element (not shown in detail here), which can have a shape corresponding to the first cutout 151 in the second state and can be attached to the first cutout 151, especially by means of an adhesive surface, to fix the plate element 100 in this second state.

[0058] Fig. Figure 5 shows a schematic side view of a plate element 100 in a second state. Fig. 2.

[0059] The second surface section 102 was moved towards the first surface section 101 and thus deformed, so that the first surface section 101 and the second surface section 102 formed a first angle A1 with each other, which is shown here as essentially 90°, and the third surface section 103 was moved away from the second surface section 102, so that the second surface section 102 and the third surface section 103 formed a second angle A2 with each other, which is also shown here as essentially 90°. Through this deformation, the first triangular section 151 was transformed from an acute to an obtuse triangle, as shown in Fig. Figure 4 shows that the trapezoidal second cutout 152, which was initially trapezoidal, was transformed into a substantially crescent-shaped form. This means that the second cover layer 122 is positioned on the outside of the second angle A2 and faces away from it. In this form, or second state, the plate element 100 can be permanently attached, or indeed is. This can be achieved, in particular, by a first connecting element (not shown in detail here), which can have a shape corresponding to the first cutout 151 in the second state, and by a second connecting element (also not shown in detail here), which can have a shape corresponding to the second cutout 152 in the second state. These connecting elements can be attached to the first cutout 151 or the second cutout 152, respectively, by means of an adhesive surface, in order to fix the plate element 100 in this second state.

[0060] Fig. Figure 6 shows a schematic side view of a plate element 100 in a second state. Fig. 3.

[0061] The first surface section 101 was moved towards the second surface section 102 and thus deformed, so that the first surface section 101 and the second surface section 102 formed a first angle A1 with each other, which is shown here as essentially 90°. Likewise, the third surface section 103 was moved towards the second surface section 102, so that the second surface section 102 and the third surface section 103 formed a second angle A2 with each other, which is also shown here as essentially 90°. The fourth surface section 104 was also moved away from the third surface section 103, so that the third surface section 103 and the fourth surface section 104 formed a third angle A3, which is also shown here as essentially 90°. Through this deformation, the first cutout 151, which in its initial state was essentially square or trapezoidal, was transformed into an L-shaped form.Likewise, the deformation transformed the essentially square or trapezoidal second cutout 152 into an L-shaped shape. The trapezoidal third cutout 153, also in its initial state, was transformed into an essentially crescent-shaped shape, as already described in [reference]. Fig. 5 explained. This means that the first cover layer 121 is arranged on the outside of the first angle A1 and facing away from it, and likewise the first cover layer 121 is arranged on the outside of the second angle A2 and facing away from it. In this form or this second state, the plate element 100 can then be permanently fastened, or rather, it is. This can be achieved in particular by a first connecting element (not shown in detail here), which can have a shape corresponding to the first cutout 151 in the second state; a second connecting element (also not shown in detail here), which can have a shape corresponding to the second cutout 152 in the second state; and a third connecting element (also not shown), which can have a shape corresponding to the third cutout 152, which can be attached in particular by means of an adhesive surface to the first cutout 151, the second cutout 152, and so on.the third cutout 153 can be attached to fix the plate element 100 in this second state.

[0062] Fig. Figure 7 shows a perspective top view of a plate element 100 in a second state. Fig. 5.

[0063] It is particularly evident how the first cutout 151, possibly with an additional connecting element, creates a transition from the first surface section 101 to the second surface section 102, which can be described as a step, whereas the second cutout 152, possibly with an additional connecting element, creates a transition from the second surface section 102 to the third surface section 103, which can be described as a rounding.

[0064] Fig. Figure 8 shows a perspective top view of a plate element 100 in a second state. Fig. 6.

[0065] The transitions between the surface elements 101, 102, 103 and 104 created by the various cutouts are also evident here, with cutouts 151 and 152 in particular creating a step with a substantially rectangular cross-section.

[0066] Fig. Figure 9 shows a perspective bottom view of a piece of furniture 1 made from a panel element 100. Fig. 8.

[0067] The piece of furniture 1 comprises a panel element 100 as shown in Fig.Figure 8 shows, as well as additionally further plate elements 200, 300 and 400, which can be constructed similarly to or identically to the plate element 100 according to the invention, and additionally a structural element 900. The structural element 900 has a higher strength than the plate element, wherein the structural element is arranged here by way of example along the third surface section 103 and the fourth surface section 104 in the second state, and supports them. The structural element 900 is in particular a body element of a vehicle, which is not shown here for the sake of clarity. The piece of furniture 1 shown here is designed by way of example as a wet cell or shower cubicle, wherein the plate element 100 according to the invention is a floor plate with an entry edge, which is formed by the first surface element 101, and a raised surface, which is formed by the fourth surface element 104.The other panel elements 200, 300 and 400 form the side and back walls of the wet cell.
