Description

[0001] Construction element, especially furniture component

[0002] The invention relates to a construction element, in particular a furniture component, which has a core component consisting of a foam material, wherein a layer component and at least one shaped element are arranged on opposite sides of the core component, wherein the shaped element is made of plastic.

[0003] Within the scope of the invention, a layered component can be a single-part or a multi-part component. As a multi-part component, it can, for example, have one or more layers. The layered component can, for example, be a material blank, in particular a flat material blank, or a molded part, in particular a formed component.

[0004] A construction element is known from DE 10 2009 003 335 A1. These construction elements use a core component made of a foam material, which is covered on both sides with a plastic sheet. The core component is surrounded by edge strips at the edges. The individual elements of the construction element are biodegradable, thus ensuring good environmental compatibility. To produce such a construction element, a plate-shaped core material is first produced from a foam. The individual layer materials are then laminated onto the core material. To create complex shapes, DE 10 2009 003 335 A1 proposes producing the individual layer materials using injection molding or extrusion processes. To give the construction element a special appearance, a decorative film can also be applied to the exterior.

[0005] With such structural elements, the production of complex, especially large-format, components proves difficult. This requires considerable equipment investment. In particular, injection-molded or extruded components can only be produced in large format with considerable machine investment.

[0006] The object of the invention is to provide a construction element, in particular for furniture construction, which can be easily manufactured at low cost with little processing effort.

[0007] This object is achieved in that the shaped element is designed as a deep-drawn component, wherein the shaped element can have a wall section and, formed thereon, an edge section projecting beyond the wall section.

[0008] The deep-drawn component can be easily manufactured from a plastic film blank or from rolled material (coil). The edge section is formed directly with the wall section in a single process step during the deep-drawing process. The edge section stiffens the wall section and ensures good component strength. The production effort, particularly for the required production machines and tools, is kept within reasonable limits, even when manufacturing large-format structural elements. Depending on the design of the machine die into which the plastic film is drawn or formed, complex and elaborate geometries can be easily produced. In addition, functional elements as well as visual ones can be integrated into the formed element. This is particularly advantageous when the structural element is used as a furniture component.

[0009] A finished foamed component can be used as the core component and joined to the molded component, or a reactive material can be applied to the molded component to form the core component, which then forms the core component. For example, an XPS, EPP or EPS material can be used as the material for the core component, but other types of lightweight materials can also be used, e.g. wood foam, corn foam, glass foam, etc. Preferably, the core component, as already mentioned above, is designed as a finished foamed, preferably plate-shaped, component. Within the scope of the invention, a plate-shaped component does not have to be designed so that it has a uniform thickness. Rather, it can also have a varying thickness.

[0010] The core component does not necessarily have to be plate-shaped, but can form any other contour.

[0011] It is advantageous if the core component is designed in such a way that it compensates for production-related unevenness and / or indentations, for example thick or thin spots, protrusions or indentations, of the layered component and / or the mold element.

[0012] The core component can also be curved, e.g., bridge-shaped. It can also follow a statically advantageous contour of the shaped element or the layered component.

[0013] Thus, the core component can follow any contour of the mold element and / or the layered component.

[0014] A kit-like construction of structural elements according to the invention is also conceivable if a core component is combined with different shaped elements and / or layered components as needed. This also simplifies assembly.

[0015] The core component can be designed in such a way that it follows the contour of the shaped element and / or the layered component at least in part, preferably completely.

[0016] For example, the core component may lie flat against the wall section and / or flat against at least one of the edge sections of the molded element. Preferably, the flat component region opposite the core component can be supported by the core component. This makes it possible to design the flat component region, for example of the molded element, with very thin walls. Preferably, a material connection, in particular an adhesive connection, may be provided in the flat connection region between the core component and the molded element and / or the layered component.

[0017] The core component can be designed such that it has a recess, such as a trough, or an opening in a component region facing the molded element and / or the layered component. For example, the core component can have a recess, such as a trough, in a region facing the edge section or the wall section of the molded element.

[0018] The recess or opening can be arranged in an edge region of the core component facing the edge section of the shaped element. Thus, the core component is then designed with an edge receptacle that is open at least on one side. Additionally or alternatively, the core component can also be provided with a recess and / or opening in a region facing away from the edge section of the shaped element, for example, in a central region.

[0019] Preferably, a separate component is arranged in the recess and / or the opening. This separate component can be, for example, a mechanical component and / or an electrical component. This allows components to be integrated into the structural element in a space-saving manner, at least in some areas. The separate component can be connected to the shaped element, the core component, and / or the layered component.

[0020] It may be the case that the separate component is at least partially covered by the edge section and / or the wall section and / or the layered component or that the separate component protrudes with a component area on the outside beyond the edge section and / or the wall section of the shaped element and / or the layered component.

[0021] If the component area of ​​the separate component protrudes beyond the edge section and / or the wall section on the outside, it can preferably have a functional area. This functional area can, for example, form a mechanically active area, such as a fastening receptacle for connecting another component or a support surface. It is also conceivable for the functional area to have an electrically, optically, or magnetically functional area.

[0022] Within the scope of the invention, the core component can be formed in one piece or it can be multi-piece, in which case the core component is composed of two or more core elements. At least two core elements can be arranged in a spaced relationship or with a gap. It is also conceivable for at least two core elements to be connected to one another, for example, by adhesive bonding.

[0023] According to a possible variant of the invention, it can be provided that the edge portion of the shaped element is formed to be at least partially circumferential and protrudes beyond the inner side of the wall portion facing the core component. In this way, the edge portion can be used functionally to protect or visually cover the edge of the core component.

[0024] If it is provided that the edge section is at least partially materially connected to the core component and / or that the core component is at least partially materially connected to the inner side of the wall section of the shaped element facing the core component, then a significant improvement in the rigidity of the structural element can be achieved.

[0025] A possible variant of the invention can be such that the edge section has at least a first section region and a second section region offset and / or at an angle to the first edge section. This allows visual accentuation of the edge section to be created. Furthermore, functional elements can also be integrated into the edge section, for example, receiving areas for add-on elements.

[0026] According to one variant of the invention, both the molded element and the layered component can be designed as deep-drawn parts with wall and / or edge sections. It is also conceivable, for example, that edge sections of the molded element and the layered element at least partially overlap. This allows for a nested construction to be realized.

[0027] According to a possible variant of the invention, the edge section can be provided with at least one edge passage, wherein the edge passage is designed as an opening or as a recess open laterally toward the end of the edge section facing away from the wall section. For example, access to the receiving area in which the core component is housed can be created via the opening. Thus, the area formed here can be used spaciously for accommodating components that, for example, partially protrude laterally from the structural element through the opening.

[0028] It is also conceivable that the opening could be used for a fastening task, whereby, for example, the edge area of ​​the opening could form a fastening element, in particular a locking element. If the opening is designed as a laterally open recess, it can be formed directly using a deep-drawing process (e.g., including trimming and / or subsequent mechanical processing (e.g., edge trimming)), so that no further post-processing is required, particularly by the furniture manufacturer and / or during final assembly.

[0029] A structural element according to the invention can be such that the wall section has a molded-on indentation which forms a partial wall section offset in the direction of the core component, or such that the wall section has a molded-on projection which projects in the direction away from the core component. Both the indentation and the projection can, with appropriate design, be easily integrated into the manufacturing process (deep-drawing process). If an indentation is used, add-on components can be fastened therein, with these add-on components then being integrated in a space-saving manner with the part with which they protrude into the indentation. This makes it possible to realize compact designs. If a projection is used, it can have a fastening surface, preferably a plateau surface which projects beyond the wall section at least in part, onto which a component can then be fastened.

[0030] It is also conceivable for the wall section to be provided with at least one passage. In this case, the passage may be surrounded, preferably at least in part, by a recess that is integrally formed onto the wall section and protrudes beyond it at the rear and / or front. The recess can be formed integrally using a deep-drawing process. It can serve, for example, to delimit the interior area in which the core component is arranged. The recess can be used functionally, for example, as a handle.

[0031] If the core component is provided with an edge-side receptacle that is laterally accessible through an edge passage of the mold element, the receptacle creates space for the arrangement of components between the mold element and the spaced-apart layer element. These components are then accessible through the edge passage or protrude through it.

[0032] It is also conceivable for the core component to form at least one receptacle that is recessed into the outer side of the core component facing the molded element, or that is recessed into the inner side of the core component facing away from the molded element, or that is formed as an opening in the core component. Additionally or alternatively, it is also conceivable for such a receptacle to be present next to the core component, preferably between the molded element and the layered component.

[0033] The receptacle forms, for example, an area in which components can be accommodated directly or indirectly. It is conceivable, for example, that the receptacle forms a compartment which is at least partially covered by the shaped element (and / or the layer element) and which is arranged between the shaped element and the layer element. Additional components can, for example, be arranged in the compartment. For example, it is conceivable that an electrical or mechanical element is arranged at least partially in the receptacle. In this way, the functionality of the structural element can be further increased. It is conceivable that a current-carrying element, for example a cable, and / or at least one sensor and / or a power supply and / or a switch, is accommodated as an electrical element in a space-saving and protected manner in the receptacle.

[0034] As a mechanical element, a structural unit can be arranged at least partially in the receptacle. This structural unit can in particular be a furniture fitting. It is also conceivable for the mechanical structural unit to have at least two components that can move relative to one another, for example in the form of a hinge. It is also conceivable for a mechanical transfer element, a mechanical fastening element, for example a fastening anchor or a spacer, to be arranged in the receptacle as the mechanical element. With the mechanical transfer element, forces and movements can be transmitted, at least partially within the structural element. This also enables a space-saving design. The transfer element can, for example, be the synchronization element, in particular the synchronization rod, of a drawer synchronization system.

[0035] A further functional improvement can be achieved if it is provided that the shaped element and / or the layered component opposite the shaped element on the other side of the core component has / the indentation which projects into the receptacle or the opening of the core component or that the passage of the shaped element, an opening of the opposite layered component and the opening in the core component form a common passage through the structural element.

[0036] In particular, it can be provided that an add-on element, in particular a furniture fitting or a handle element, is arranged, at least in part, in the recess. Thus, prefabricated fastening areas can be integrated into the deep-drawn part, which can be formed using the deep-drawing process and serve as positioning aids and / or mounting areas for add-on elements. This eliminates the need for additional manufacturing effort, as is necessary, for example, with conventional chipboards used in furniture construction. For example, cup holders for concealed hinges or recessed grips for handles can be integrated into the structural element. A wide variety of other applications are conceivable.

[0037] If the core component is designed as a plate-shaped component, simple production is possible, as such plate-shaped materials can be easily manufactured at low cost (e.g., by laser or waterjet cutting, hot wire cutting, machining, etc.) or obtained as semi-finished products. It is also conceivable for the core component to be composed of several core elements in order to easily create complex geometries. Advantageously, the core component is manufactured using a tool-based particle foam process (EPS, EPP, etc.).

[0038] It is conceivable that the core component is made at least partially from a biodegradable material, for example from wood foam, paper foam, corn foam, PLA foam or the like.

[0039] According to a possible variant of the invention, it can be provided that the wall section has, on its outer side opposite the core component, a contour region that is set back in the direction of the core component, wherein it is preferably provided that a set-back contour region is arranged on each of the lateral and opposite edge regions of the wall section. The set-back contour regions can also be easily integrated into the deep-drawing process, so that no additional manufacturing effort is required. If such contour regions are provided on both sides, furniture bases, in particular drawer bases, can be easily manufactured, with the fastening sections of lateral drawer frames finding space in the contour regions. Such components can also be realized by nesting the shaped element and the layered element.

[0040] The molded element and the opposing layered element can be made of the same material. However, it is also conceivable for the layered element opposite the molded element to be made of a different material than the molded element, particularly metal. High strengths can be achieved with the structural element, particularly when using a metal material. The molded element and / or the layered component can be made, at least in part, of a preferably biodegradable material, for example, polylactide (PLA), polybutylene succinate (PBS), polybutylene (PBAT), and / or a PLA-PBAT blend.

[0041] It is conceivable that the molded element consists of a single-layer material or, at least in some areas, a multi-layer material. It is conceivable that two or more layers are coextruded to provide the starting material for the molded element. It is conceivable that a hard carrier layer is combined with a softer layer, e.g., a "rubber coating." This can advantageously be used to manufacture a shelf with an included anti-slip mat, for example. It is also conceivable that an ABS material is combined with an ASA material, in particular coextruded. This has the advantage that the ASA layer makes the structural element UV-resistant.

[0042] Furthermore, surfaces with so-called grains can be used, which have structures that create decorative surfaces, e.g., wood, leather, textile, concrete, or even marble or stone. These decorative surfaces can be made from single- or multi-layer films / panels.

[0043] In addition, the surfaces can be made of flame-retardant materials or electrically conductive material

[0044] In general, so-called composite panels (co-extruded or multi-extruded) offer a variety of advantages.

[0045] The following materials can be used as material for the mold element and / or the layered component:

[0046] ABS, ASA, HD-PE, PC, PET-A, PET-G, PMMA, PP, or PS-PE. Blends such as PC-ABS and PS-PE are also possible.

[0047] It is also conceivable to use composite or multi-layer materials, for example ASA-ABS, TPU-ABS, TPE-ABS, ABS+PC, HIPS+PE (HIPS: High Impact Polystyrene), PMMA-ABS (PMMA = Plexiglas).

[0048] It is also conceivable for the molded element, the layered component, and / or the core component to comprise a ferromagnetic component, in particular a ferromagnetic layered element. For example, components such as drawer bottoms or wall elements can be realized in this way, to which magnets can be attached. Preferably, such a ferromagnetic component is assigned to the wall section and / or the edge section of the molded element.

[0049] The use of high-performance plastics such as PPSU (polyphenylsulfone) is also conceivable.

[0050] According to a possible variant of the invention, the molded component and / or the layered element may have an opening. This opening forms an opening through which components can be mounted.

[0051] For example, it is conceivable that the opening serves as a cable duct.

[0052] It is also conceivable for the opening to form an undercut with its edge region facing the core component. A fastening element can be designed such that it is inserted into the opening and securely engages behind the undercut with an anchor. In this way, a positive connection can be created between the shaped element and / or the layered component and the fastening element. The undercut can, for example, be part of a recess projecting toward the core component, which at least partially surrounds the opening of the opening. The invention is explained in more detail below with reference to exemplary embodiments illustrated in the drawings. In the drawings:

[0074] Figure 1 shows a construction element 10 according to the invention using the example of a furniture door. The structure of the construction element 10 is more clearly shown in Figure 2, where Figure 2 shows the construction element 10 in an exploded view.

[0075] The following explanations of Figures 1-17 are directed to specific structural elements 10, in particular furniture components. However, the following explanations should not be understood as being limited to furniture components, but can be understood in particular for any other structural elements 10, especially for the construction of complex structures.

[0076] As illustrated in Figure 1, the structural element 10 has at least one shaped element 20 made of plastic and manufactured as a deep-drawn component. This shaped element 20 can be made, in particular, from a foil blank or from a roll, which is placed on a deep-drawing die in a deep-drawing machine. After the foil has been tempered, the shaped element can be sucked onto the deep-drawing die using negative pressure (vacuum) and / or pressed onto the deep-drawing die using positive pressure.

[0077] It is conceivable that the die has a surface structuring which is then transferred to the facing side of the foil blank and thus to the forming element 20 in order to create a corresponding appearance.

[0078] Furthermore, it is conceivable that the die has elevations or depressions, which then appear as depressions or elevations on the molded part. This will be explained in more detail below with reference to Figures 1-17.

[0079] As Figure 2 illustrates, the molded element 20 has a wall section 21 that is flat and has at least one edge section 22, 23 at its edge. It is not necessary for the edge section 22, 23 to terminate the wall section 21 on the outside. Rather, the edge section 22 can also be arranged at any other desired location on the wall section 21. For example, it is conceivable that the edge sections 22 are attached to the molded part and the edge sections 23 are formed by an opposing layered component. Any arrangement is possible.

[0080] In the present embodiment, the edge sections 22, 23 form a circumferential contour that terminates the edge of the wall section 21. The edge sections 22, 23 protrude beyond the inner side of the wall section 21. However, it is also conceivable for at least one of the edge sections 22, 23 to protrude beyond the front side of the wall section 21.

[0081] Figure 2 further illustrates that the shaped element 20 can be provided with at least one passage 25, which is formed as an opening, for example, in the wall section 21 and / or the edge section 22, 23. The passage 25 can be created, for example, in a punching process following the deep-drawing part process or as a bore.

[0082] A core component 30 consisting of a foam material can be inserted into the area surrounded by the edge sections 22, 23. As shown in Figure 2, the core component 30 can be manufactured from a plate-shaped blank, or, for example, using a tool-bound particle foam process. The core component 30 can be formed in one piece or in multiple pieces. The core component 30 has an outer side 32 facing the molded element 20. Opposite, the core component 30 has an inner side 31 facing a layered component 40.

[0083] The core component 30 can have a peripheral edge 33 that faces the edge sections 22, 23 of the molded element 20. Preferably, the core component 30 is integrally connected by its outer side 32 to the inner side of the wall section 21. Additionally or alternatively, it can be provided that the edge 33 is integrally connected, e.g., glued, to the edge sections 22, 23 on the inside.

[0084] Figure 2 illustrates that, within the scope of the invention, the core component 30 can be provided with an opening 35. In the present embodiment, several openings 35 are provided. Two of the openings 35 are aligned with the passages 25 of the molded element 20.

[0085] As shown in Figure 2, a layered component 40 can be connected to the shaped element 20. The layered component 40 has an inner wall 41 facing the core component 30 and an outer wall 42 facing away from the inner wall 41. The layered component 40 can be connected to the core component 30 and / or the shaped element 20. For example, the layered component 40 can be connected, in particular materially bonded, by its inner wall 41 to the inner side 31 of the core component 30. Additionally or alternatively, the layered component 40 can also be materially bonded, for example glued or welded, to the shaped element 20 at its edges, in particular to the edge sections 22, 23. Preferably, the layered component 40 is connected to the shaped element 20 all the way around.

[0086] As Figure 2 shows, the layered component 40 can be provided with at least one opening 44. In the present case, several openings 44 are used, two of the openings 44 being aligned with the openings 35 of the core component 30 and the passages 25 of the shaped element 20 to form a continuous passage through the structural element 10. For example, this passage can then be used to pass through a fastening element 45, by means of which, for example, on the front side, an add-on element, for example a handle element 24, is connected to the structural element 10, in particular the shaped element 20.

[0087] As shown in Figure 2, the layered component 40 may have a recess forming a receptacle 43. The receptacle 43 may be formed as a recess that protrudes beyond the inner wall 41 of the layered component 40 and projects into a recess in the core component 30 or into an opening 35 in the core component 30.

[0088] As Figure 2 shows, the receptacle 43 can, for example, be designed as a cup-shaped receptacle. The receptacle 43 can, for example, serve to fasten an add-on element 50, in particular a furniture fitting, to the structural element 10. In the present exemplary embodiment, a furniture hinge of known design is inserted with its hinge cup into the receptacle 43 on the back of the layered component 40. It is possible for the layered component 40, like the shaped element 20, to be manufactured as a deep-drawn part from a foil blank in order to further simplify production. This is also intended to be within the scope of the invention.

[0089] Figures 3 and 4 show the use of the invention for producing a drawer base. This drawer base forms a structural element 10 according to the invention, which can be connected to an attachment element 50, namely a side wall 54 of a drawer. The side wall 54 forms a frame having a support section 51. The support section 51 has a mounting flange 52 with screw receptacles 53.

[0090] The shaped element 20 is again designed as a deep-drawn component and has a wall section 21 which has at least one edge section 22, 23.

[0091] On its opposite longitudinal sides, the shaped element 20 has lateral shoulders 21.1, to which partial wall sections 21.2 adjoin. These partial wall sections 21.2 are formed as recessed surfaces, as can be clearly seen in Figure 4. The recessed areas thus formed form contour areas 28, which serve to receive the support sections 51 of the side wall 54, as shown in Figure 3.

[0092] The screw receptacles 53 are aligned with receptacles formed by recesses 26 of the shaped element 20. The recesses 26 are formed using a deep-drawing process and are thus integrally formed, in particular, onto the wall sections 21. The recesses 26 form screw receptacles that are open at the bottom. Fastening screws can be passed through the screw receptacles 53 of the support section 51 and screwed into the recesses 26, with the threads of the fastening screws preferably penetrating the wall of the recesses 26, thus eliminating the need for additional fastening elements.

[0093] As shown in Figure 4, the core component 30 is shaped to fit the volume area formed by the edge sections 22, 23 and the wall section 21, so that it completely or almost completely fills it. The core component 30 has receptacles 34, which are preferably formed as openings 35. These receptacles 34 are aligned with the indentations 26, so that when the core component 30 is assembled, the indentations 26 fit into the receptacles 34.

[0094] A layered component 40 can again be connected to the shaped element 20, as described above with reference to Figures 1 and 2.

[0095] Alternatively, the layered component can also be designed as a deep-drawn part and have corresponding edge sections. This can also be nested with the molded element.

[0096] Figures 5-7 show a further embodiment of the invention, with identical components being provided with identical reference numerals. Therefore, only the differences will be discussed below, and reference is made to the above explanations.

[0097] The structural element 10 shown in Figures 5-7 is a furniture front panel, in particular a drawer front panel. As Figure 5 illustrates, the shaped element 20, which is manufactured as a deep-drawn component, has edge sections 22, 23, which preferably form a circumferential edge. At least one of the edge sections 22, 23 has a first section region 22.1, which is integrally formed with the wall section 21 and angled therefrom. A second section region 22.2 adjoins the first section region 22.1 in an offset and / or angled manner. In this way, a visually appealing bevel can be created on the edge sections 22, 23, as illustrated in Figure 7. However, other design elements are also possible.

[0098] Figure 5 also illustrates that a molded element 20 according to the invention can have at least one molded-on indentation 26 on its wall section 21. In the present exemplary embodiment, the indentation 26 forms a receptacle into which a handle element 24 can be inserted. For example, the handle element 24 can be pressed or glued into the indentation 26. The indentation 26 protrudes beyond the rear side of the wall section 21. For a space-saving design, the core component 30 can have a receptacle 34 in the form of an opening 34 or in the form of a depression to accommodate the indentation 26 on the rear side.

[0099] The layered component 40 is again provided with receptacles 43 formed by indentations molded onto the outer wall 42 of the layered component 40. The receptacles 34 thus form indentations that protrude beyond the inner wall 41 of the layered component 40. For a space-saving design, the areas of the receptacles 43 that protrude beyond the inner wall 41 at the rear find space in receptacles 34, in particular openings 35 in the core component 30. The receptacles 34 can be used to accommodate dowel elements 56 of an add-on element 50. Alternatively, screwing can also be carried out directly into the receptacles 34 without dowels. In the present exemplary embodiment, an add-on element 50 is shown, which has a front wall holder that carries two dowel elements 56. The front wall holder can be connected to the structural element 10 by means of the dowel elements 56.

[0100] Figures 8 and 9 show the use of the invention on a rear wall holder 55 of a drawer. As these drawings show, at least one of the edge sections 22 may have at least one edge passage 27, which may be formed as an opening. The edge passage 27 provides access to the area formed behind the inner side of the wall section 21, in which the core component 30 is housed. In the area behind the edge passage 27, recessed receptacles 34, for example, may be present on the core component 30 to create a receiving space.

[0101] In the present exemplary embodiment, edge passages 27 are provided on opposite sides of the structural element 10. These edge passages 27 serve to fasten the structural element 10 to an add-on element 50, in particular to the drawer frame shown in Figure 9. The drawer frame has a rear panel holder 55 with locking lugs 55.1. The locking lugs 55.1 extend through the edge passages 27 and fasten on at least one of the edges delimiting the edge passage 27. The projecting sections of the locking lugs are accommodated in the area of ​​the receptacles 34 of the core component 30. Of course, this technology is not limited to use with a structural element 10 in the form of a drawer rear panel. Rather, this type of locking fastening can also be implemented with any other structural elements 10 according to the invention.

[0102] Figures 10 and 11 show a further embodiment of the invention. Here, too, as in all other embodiments shown in the figures, the same reference numerals are provided with the same terms. Reference may therefore be made to the corresponding explanations.

[0103] As the illustrations show, the structural element 10 can be designed in the form of a furniture side wall. The structural element 10 has an edge passage 27 on its shaped element 20 in the region of an edge section 22, which can be open toward the end facing away from the wall section 21, as shown in Figure 11.

[0104] It may be that the core component 30 forms a receptacle 34 in the area behind the edge passage 27, which is then laterally recessed from the core component 30. In the assembled state, the receptacle 34 forms a receiving space in the structural element 10 for accommodating fastening elements or the like.

[0105] In the present embodiment, a holding element 46 is attached to the inside of the layer component 40 and projects into the area surrounded by the receptacle 34 of the core component 30.

[0106] Figure 10 shows the assembled state of the structural element 10. As this illustration illustrates, the receptacle 34 is laterally accessible through the edge passage 27, so that, for example, a furniture fitting, such as a flap holder or a flap fitting, can be inserted into this area. The furniture fitting can be connected to the structural element 10, for example, via the retaining element 46. It is conceivable that one or more openings 44 are provided, for example, on the layered component 40, for screwing the furniture fitting to the layered component 40. In the illustration according to Fig. 10, molded-on suspension hooks are shown as 44 for positively receiving the furniture fitting. (Enlarged image in the appendix)

[0107] For a stable construction, it can be provided that the layered component 40 consists of a different material than the shaped element 20. For example, the layered component 40 can be formed from a metal plate, in particular a steel plate.

[0108] Figures 12 and 13 show a variant of a structural element 10 in which the shaped element 20 has a passage 25 that is circumferentially surrounded by a recess 25.1. The recess 25.1 is formed as a single piece onto the wall section 21, but can also be formed entirely or partially onto the layered part. A receptacle 34 in the form of a passage is provided in the core component 30, into which the recess 25.1 projects. An opening 44 is provided in the layered component 40, aligned with the passage 25. In this way, a passage is formed through the structural element 10 in the assembled state, as shown in Figure 12. This passage can be used, for example, as a handle. The recess 25.1 separates the passage from the area in which the core component 30 is received.

[0109] Figures 12 and 13 illustrate that a structural element 10 according to the invention can be geometrically designed in a variety of ways without requiring additional manufacturing effort due to the design. For example, the molded part 20 can have a wave shape in the area of ​​its wall section 21 or, as shown in Figure 4, offset contour areas 28. Furthermore, any 3D freeform surfaces are possible.

[0110] As shown in Figures 14 and 15, a structural element 10 according to the invention can be used, for example, as a shelf for a piece of furniture. In this case, the structural element 10 may form a laterally open passage 25. For this purpose, the shaped element 20, the core component 30, and the layered component 40 are designed accordingly, as shown in the figures.

[0111] Figure 15 illustrates that the core component 30 does not have to be formed from a single component. Rather, within the scope of the invention, the core component 30 can be composed of several core components 30.1, 30.2. It is also conceivable for a reinforcement to be integrated into the structural element on or in the core component 30. The reinforcement can, for example, comprise at least one reinforcement element, which can be designed as a strut.

[0112] Figures 16 and 17 show the diverse design possibilities possible with the invention on a single structural element 10. The same reference numerals refer to the same components, so that reference can be made to the above explanations to avoid repetition.

[0113] Therefore, only the differences are explained below. As these illustrations show, the shaped element 20 can have a variety of designs, with offset partial wall sections 21.1 being used on the wall section 21 to form optical design elements.

[0114] Within the scope of the invention, it is also conceivable that fastening domes 29 can be integrally formed on the shaped element 20, in particular the wall section 21, to which components can be fastened, in particular screwed. It is conceivable that a fastening dome 29 is arranged at least partially within a recess 26 in order to realize a space-saving design, as shown in Figure 16.

[0115] Figure 17 also illustrates that an insert 60 can be inserted into a laterally open receptacle 34 of the core component 30. In this case, the insert 60 can be accessible through an edge passage 27 and / or through an opening in the wall section 21 and / or the layered component 40. In the present exemplary embodiment, accessibility is only provided via an edge passage 27 in the region of the edge section 23. The insert 60 can, for example, be manufactured in such a way that it enables the stable coupling of an add-on element to fastening sections 63, or it can, for example, be used as a cover for an inserted functional unit.

[0116] For example, the insert 60 may comprise a base part 61 to which two legs 62 are molded at a distance from each other. The two legs 62 carry the fastening sections 63 on their facing sides.

[0117] As a further example, it is conceivable that a battery compartment or something similar could be created using an insert.

[0118] Figures 18 and 19 show a structural element 10 that is essentially identical to the structural element shown in Figures 3 and 4. Reference can therefore be made to the above explanations. In particular, identical components are provided with identical reference numerals. Therefore, only the differences will be discussed below.

[0119] As the drawings show, the layered component 40 is formed as a formed, in particular deep-drawn, component. It again has an inner and an outer wall 41 and 42. Furthermore, the layered component 40 has a molded edge 47 that protrudes toward the molded part 20. The edge 47 overlaps with the edges 22, 23 of the molded element 20, at least in some areas, to form a nested structure. The edges 22, 23, and 47 can be integrally connected to one another, for example, by adhesive bonding or welding.

[0120] Figures 20 and 21 show a further embodiment of a shaped element 20, which in its basic form essentially corresponds to the shaped element 20 according to Figures 18 and 19. Reference can therefore be made to the above explanations. As the illustration shows, the shaped element 20 can have integrally formed, in particular deep-drawn, indentations 26, which can be web-like and protrude beyond the wall sections 21. These indentations 26 stiffen the shaped element 20.

[0121] The layered component 40 shown in Figure 18 can be connected to the shaped element 20. For example, the edges 22, 23, 47 can be connected to one another in an overlapping manner. Additionally or alternatively, it can also be provided that the layered component 40 rests with its inner wall 41 on the indentations 26 and is preferably connected to them, for example, by a material bond.

[0122] Figure 22 shows a further embodiment of a structural element 10. Identical components are again designated with the same reference numerals so that reference can be made to the above explanations.

[0123] The structural element 10 again has a shaped element 20 with a wall section 21 and edge sections 22, 23. A reinforcement 70 is accommodated in the area enclosed by the edge sections 22, 23. This reinforcement 70 has at least one reinforcing element, which is arranged at least partially in the cavity enclosed by the structural elements 10. As the drawing shows, the at least one reinforcing element can be formed by a longitudinal and / or transverse strut 71, 72. It is advantageous, as shown in the exemplary embodiment, if the longitudinal and transverse struts 71, 72 of the reinforcement 70 form a lattice-like structure.

[0124] Figure 22 also shows that it can advantageously be the case that the reinforcement element(s) is assigned to the core component 30. In the present exemplary embodiment, the core component 30 consists of several individual core component elements. However, it can also be the case that various core component elements are joined to form a combination part or are formed integrally with one another.

[0125] Finally, it may again be the case that the layered component 40 is connected to the shaped element 20.

[0126] In the assembled state, the reinforcement 70 stiffens the structural element 10. Preferably, the inner wall 41 of the layered component 40 and / or the inner side of the wall section 21 of the shaped element 20 is supported on at least one region of the reinforcement 70. Advantageously, the inner wall 41 of the layered component 40 and / or the inner side of the wall section 41 of the shaped element 20 is supported on at least one region of a longitudinal and / or transverse strut 71, 72 of the reinforcement 70.

[0127] Finally, the reinforcement 70 shown in Figure 22 can also be combined in a further, not shown embodiment of the invention with a stiffening indentation 26 of the shaped element 20 or of the layered component 40, as shown for example in Figures 20 and 21, in order to achieve additional stiffening.
