Description

[0001] The present invention relates to a kit consisting of components for the manufacture of furnishings, the kit comprising at least one support block and support struts that can be inserted therein.

[0002] German patent DE 100 22 930 A1 describes furniture composed of several panel-shaped individual parts held together by connectors. Furthermore, German patent DE 10 2018 103 114 A1 describes a camp bed comprising a four-legged, foldable frame made of a flat, renewable raw material and a covering as a lying surface.

[0003] Prior art DE 10 2014 106 608 B3 discloses kits for foldable compartment structures. The basis for the furniture that can be constructed from these kits is a compartment structure that can be collapsed when the furniture is not in use. However, it is not disclosed that the respective contact surfaces have folded edges. Just like the kit of the present invention, the prior art kit uses sustainable materials.

[0004] Furthermore, DE 10 2015 001 581 A1 discloses furniture pieces that can be constructed from many different components. The furniture is assembled using a plug-in method. This requires a positive-locking connection consisting of a slot, a recess extending from the slot, a slot in the opposite component, and a laterally acting locking element. However, it is not disclosed that the furniture pieces can be manufactured from flat, foldable materials. Further kits are known from DE 8812414U1 and DE 202021101494U1.

[0005] The kits described in the prior art have significant disadvantages. Firstly, assembling the furniture is often difficult because a large number of components are used, and in many cases connectors or fasteners also need to be attached. Furthermore, the load-bearing capacity of the components is not advantageous because it is very low.

[0006] The object of the present invention is therefore to provide components of kits with which stable furnishing objects can be produced from flat, foldable materials. The components of the kits essentially comprise support blocks and support struts that can be inserted therein.

[0007] The problem is solved by providing a kit consisting of components according to the features of the main claim. Advantageous embodiments are described in the dependent subclaims.

[0008] A kit consisting of at least two support blocks is preferred according to the invention.

[0009] According to the invention, it is particularly preferred that the support struts have two or more folding marks. It is especially advantageous that the support struts have at least one folding mark in the transverse direction.

[0010] A kit is particularly preferred in which at least two support struts can be inserted together into a slot of the support block.

[0011] According to the invention, the folded support strut is designed with 2, 3 or 4 layers. It is further preferred that the support strut is designed as a roll fold, gatefold, accordion fold, zigzag fold, parallel center fold or cross fold.

[0012] A further preferred aspect of the invention is a kit in which the support strut has locking slots on the narrow side inserted into the support block, wherein the locking slots of the support strut are receptacleable in the slots of the support block.

[0013] A kit is also preferred in which the support block has at least two fold marks in the transverse direction to form a U-shaped arrangement.

[0014] It is particularly preferred that the support block has two components in a U-shaped arrangement, which can be joined together in abutting position and the slots can be arranged to overlap each other.

[0015] It is particularly preferred that the support block comprises two U-shaped components and at least two non-folded components and / or folded components, the arrangement of which forms a rectangularly arranged support block and the slots can be arranged to overlap each other.

[0016] A further preferred aspect of the invention is a kit in which the support block is designed in the form of a triangular prism, one side edge of which is the support area.

[0017] Furthermore, according to the invention, a kit is preferably comprised of at least one connecting element which engages in the outer support struts and locks the previously assembled furnishings together. The connecting element according to the invention has folded edges. The connecting element is then formed in a U-shape and locked next to the support struts.

[0018] The connecting element can be used particularly advantageously to extend, and especially to widen, a piece of furniture, such as a bed or a platform, to any desired size. According to the invention, extending the furniture is possible by providing multiple support blocks and struts. Therefore, furniture of any size can be created from the components.

[0019] According to the invention, it is particularly preferred that the at least one support block and / or the at least two support struts of the kit are made of double-wall corrugated cardboard, in particular of corrugated cardboard in BC wave form.

[0020] Furthermore, the object of the invention is solved by providing a piece of furniture which is manufactured from a kit according to the invention and is in the form of a bed, a table, a stool, a platform, a bench, a seat or a lying surface.

[0021] According to the present invention, it is possible to extend the furniture in length and width. If the furniture is extended in length, additional support brackets are added, which are then secured by means of the added support struts. In this way, for example, a table can be extended as desired. If the furniture is to be widened, connecting elements are inserted into the existing pieces, such as a bed or platform, and secured.

[0022] The present invention is explained in more detail with reference to the accompanying drawings. These show: Fig. 1a a view of the support strut 1 as a cross-section, Fig. 1b as a perspective view and Fig. 1c as a side view; Fig 2 the cross-sectional view of the support strut 1 in the form of corrugated cardboard; Fig. 3 Cross-sectional views of different embodiments of the folded support struts 14, 15, 17; Fig. 4 the folding of the support strut 16 into a cross fold; Fig. 5a a perspective view of the arrangement of the support blocks 8 and the support strut 15 in separate arrangements, Fig. 5b in a combined arrangement of the support blocks 8 and Fig. 5c in a fully assembled arrangement; Fig. 6 a perspective view of the arrangement of the support blocks 8, 9 and the support strut 1, including a detail view; Fig. 7a a perspective view of an assembled kit in the form of a bed and Fig.7b an exploded view of the kit according to Figur 7a ; Fig. 8a a perspective view of the arrangement of the support blocks in the form of triangular prisms 10, the support struts 1 and the cover plate 11 and Fig. 8b in a fully assembled arrangement of the kit components.

[0023] According to the invention, the kit consists of at least one support block and at least two support struts, wherein the support struts can be inserted into at least one slot in the upper area of ​​the support block.

[0024] The components used according to the present invention are formed from flat, foldable materials. These materials can consist of cardboard, corrugated board, carton, plastic, metal, woven textiles, or composites of the aforementioned materials. Materials are particularly advantageous in which the components have a protective layer selected from water-repellent and / or fire-retardant materials and / or a decorative layer selected from paints, films, varnishes, textiles, and / or flocking.

[0025] According to the invention, flat, foldable materials made of corrugated board are advantageous. Double-wall corrugated boards are particularly advantageous. These double-wall corrugated boards, also called duplex or combination-wall boards, have an outer liner, a lower liner with a small gap to the adjacent liner and relatively low height, an intermediate liner, a wider liner with a larger gap and greater height than the liner above it, and an inner liner on the underside. The double-wall corrugated board described here, also known as BC-flute, is particularly advantageous because the support struts required for the 180° fold do not damage or tear the outer liner when the fold edge is formed towards the outer liner of the corrugated board during folding. This results in a smooth surface that can be used as a bearing surface for other components.

[0026] The flat components, namely the support blocks and support struts, have a length and a width, and thus a longitudinal and a transverse direction. Folding marks can be positioned on these components, either longitudinally (along the length of the components) or transversely (along the width of the components). Therefore, folding marks can be arranged on the support blocks and support struts in any desired configuration and in any number, both longitudinally and / or transversely. During assembly of the resulting furnishings, the components are then folded along the respective folding marks and fitted together accordingly.

[0027] The support stand is the component according to the present invention, which can, for example, be placed on the floor. The support stand has an upper section and a lower section. The lower section is the section that rests on the floor. The term "upper section" in the context of the support stand is defined such that the support stand, in order to secure the components to be placed on it, can be placed on a flat surface, and thus the upper section is separated from the lower section. The upper section of the support stands is further defined as the support area. In the upper section, i.e., the support area, of the support stand, slots for receiving the support struts are arranged in any number. The slots are advantageously arranged at equal intervals from one another to optimize the insertion of the support struts. The support stand can have any geometric shape.Preferably, support blocks are described which are designed in the form of a cuboid or a triangular prism.

[0028] However, according to the invention, other support blocks can also be used as components of the inventive kit. The crucial point is that slots are provided in the support area for receiving and, if necessary, locking the support struts.

[0029] Preferably, the cuboid support block can be assembled from several components. The individual flat components, for example, have fold marks in the transverse direction, so that the components can be folded to form a U-shaped support block, with each component then being folded at 90°.

[0030] These U-shaped components, namely the support brackets, offer particular advantages. Due to the parallel arrangement of the two side pieces for receiving the support struts, the invention provides for the support struts to be positioned only halfway between the parallel side pieces. This allows the furnishings to be manufactured in an extended form. It is therefore possible to use any number of U-shaped support brackets. This is particularly advantageous for tables, benches, or platforms.

[0031] It is further provided according to the invention to increase the width of the U-shaped support blocks. For this purpose, at least one longitudinally foldable support block is advantageously used. The two previously produced U-shaped, transversely folded support blocks are then moved apart, and the longitudinally foldable support block, or alternatively the unfolded support blocks, are arranged such that the slots of the support blocks arranged one behind the other are locked with the support struts. These arrangements described herein can be seen in the accompanying figures and are described accordingly herein.

[0032] The support struts disclosed herein according to the invention have at least one longitudinally arranged fold mark. This fold mark serves to fold the support strut into a 2-layer, 3-layer, 4-layer, or multi-layer embodiment. The fold is designed to have a bend of approximately 180°. The folded support strut is then inserted into the slots of the support blocks. The advantage of this is that the folded surfaces of the support struts do not need to be attached or glued to each other or to other components. Insertion into the slots of the support blocks ensures that the struts are secured in the slots, as pressure is exerted along the fold, thus counteracting the fold's restoring force. A further advantage of the support struts according to the invention is that a smooth fold edge is formed.This smooth folded edge on the upper side serves as the bearing surface for the assembled kit and therefore does not damage components such as mattresses, cover plates, cushions, and the like. Furthermore, the invention provides that locking slots are provided on the lower side of the support struts, which can be locked into the slots of the support blocks. This ensures that the support struts cannot be moved longitudinally without being removed from the slots, as this could compromise the stability of the assembled kit.

[0033] The components assembled in this way thus ensure high stability and, advantageously, also easy assembly of the furnishings. Subsequent disassembly of the furnishings is also simple, as no tools are required. Furthermore, defective components can be easily replaced or exchanged.

[0034] In summary, it can be stated that the kits of the present invention allow gaps to be bridged, preferably with corrugated cardboard, without the need for further stabilization. For this purpose, the support struts according to the invention are provided, which will be explained in more detail below.

[0035] The combination of the components according to the invention makes it possible to provide furnishings that are variable in length, height, and width. The resulting furnishings are comparable to culturally known furniture in terms of their design, i.e., their visual appearance and functionality. Furthermore, it is a key factor that the furnishings, although made from sustainable materials, are nevertheless suitable for long-term use.

[0036] The surprising stability, sturdiness and durability of the furnishings according to the invention were confirmed to the applicant by positive tests according to the standards DIN EN 12521:2015, DIN EN 1730:2012, DIN EN 1725:2018 and DIN EN 10 1022:2019 by an accredited testing laboratory.

[0037] The following examples illustrate the invention in more detail without limiting its scope. The present invention is described below with reference to the Fig. 1 bis Fig. 18 explained in more detail.

[0038] Fig. 1 shows several views of the support strut 1 according to the invention. Fig. 1a Figure 1 is a cross-sectional view of the support strut 1. The support strut 1 consists of a flat material, which preferably has at least one fold mark 6 along which the flat material is folded by up to 180°, thus forming the support strut 1. The resulting fold edge 12 has a curved surface, which is advantageous because no edges are formed on the side of the support area of ​​the assembled kit. Fig. 1b The support strut 1 is shown in perspective view and in the Fig. 1c Figures 1b and 1c show the locking slots 4, which can be engaged in the slots 3 of the support blocks 2, 8, 9, 10, 19, 20. The arrangement of the locking slots 4 in the support struts 1 is advantageously selected such that the locking slots 4 can be engaged in U-shaped support blocks 9, 19 to fix their U-shaped profile. The spacing of the locking slots 4 is therefore selected such that it corresponds to the spacing of the side parts of the U-shaped profile when the support block is assembled. Only one locking slot 4 is provided on the opposite side of the support strut 1, since, for example, when using several support blocks 8, 9, 19, 20, the support strut 1 only needs to be inserted into one side part of the U-shaped profile 8, 19.However, it is clear that when using only two support blocks 8, 19, at least four locking slots 4 are provided in a corresponding arrangement on the underside of the support strut 1. This is shown, for example, in the . Fig. 14 The support strut 1 shown there has four locking slots 4. Four locking slots 4 are required if the support struts are only to be arranged on two support blocks. However, it is also possible to arrange four locking slots 4 in each of the respective support struts 1, even if these support struts are to be arranged in several support blocks.

[0039] Fig. 2 Figure 1 is a cross-sectional view of the support strut 1, which is made of corrugated cardboard. The longitudinal fold mark 6 of the support strut 1 is located opposite the fold edge 12. The support strut is then folded along the fold mark 6. The fold edge 12 forms the bearing area of ​​the support strut 1. The fold edge is shown to be curved, with a smooth surface. This smooth surface has the advantage that objects placed on it, such as mattresses or cover plates, can be easily slid without damaging the surfaces of the objects. It is particularly advantageous (not shown) if the corrugated cardboard has two different sides. The side aligned with the fold edge 12 has finer corrugations, while the side opposite the fold edge 12 has wider corrugations.This advantageously prevents the folded edge 12 from tearing open during folding.

[0040] In the Fig. 3 Cross-sectional views of various embodiments of the folded support struts 14, 15 are shown. Fig. 3a shows a simple V-fold and thus forms a 2-layer support strut 15, with the bend being approximately 180° along the fold mark. Fig. 3b Figure 15 shows the parallel arrangement of two 2-layer support struts, with the folded edges each oriented towards the top. Fig. 3c shows a leporello-like fold, in which a 3-layer support strut 17 is designed. In the Fig. 3d A 4-layer support strut 14 is shown, which is designed in the form of an altar fold, which is also referred to as an eight-sided window fold. Fig. 3e Figure 14 shows a 4-layer support strut in the form of a parallel center fold. The variant of the support strut is shown below. Fig. 3e is characterized by the fact that the upper edge of the support strut 14 has no gap. Fig. 3f shows a 4-layer support strut 14, which is designed in the form of a variant of the leporello fold, which is called a Swiss fold. Fig. 3g shows another accordion fold, which forms a 4-layer support strut 14. The one in the Figur 3 The illustrated variants of the support struts 14, 15, 17 represent known folding variants. It is clear that, in addition to the 2-, 3-, and 4-layer support struts 14, 15, 17, support struts with any number of layers can also be produced.

[0041] In the Fig. 4 A perspective view of the cross-folded support strut 16 is shown. Fig. 4a Figure 1 shows the planar arrangement of the support strut 16 which has not yet been folded. This support strut 16 has a folding mark 6 arranged centrally in the longitudinal direction and a folding mark 7 arranged centrally in the transverse direction. Fig. 4b shows that the rear part of the support strut 16 is folded along the transversely arranged fold mark 7. In the Fig 4c The fold along fold mark 7 is shown at almost 180°. Fig. 4d Figure 1 now shows the further folding of the support strut 16 along the longitudinally arranged fold mark 6, with the fold edges 12 along the support strut 16 being shown. It is clear that due to the cross-folded arrangement of the support strut 16 in the area of ​​the fold mark 7, no open surfaces are formed at the fold edges. This has the advantage that smooth and curved surfaces are formed on the end faces of the support struts 16. This is particularly important in the case of the Fig. 7a und 7b The illustrated kit is advantageous, but can also be used for all other kits according to the present invention.

[0042] In the Fig. 5 A perspective view of the arrangement of two support blocks 8 is shown. Fig. 5a shows the components of the 2-layer support strut 15 and the support blocks 8 in a separate arrangement. Fig. 5b Figure 8 shows the arrangement of the support blocks 8 in an overlapping configuration. This arrangement can be configured as desired. The U-shaped design of the support blocks 8 allows one component 8 to be positioned inside the other component 8, or each side of component 8 to be positioned on the outside of the other component 8. In the Fig. 5c Finally, the insertion of the support strut 15 into the slots 3 of the assembled support blocks 8 is shown. The following is shown in this Figur 5c The support strut 15 shown is 2-layered and the fold edge 12 is aligned towards the support surface.

[0043] In the Fig. 6 Figure 1 shows a perspective view of the arrangement of the support blocks 8, 9 and the support strut 1, as well as a detailed view of the connection between these components. This view essentially corresponds to the example of the Fig. 7b The U-shaped support block 8 also has a cover tab 13. This cover tab 13 advantageously secures the U-shaped arrangement of the support block 8. Components 9, which are flat, are inserted into the inner surfaces of the U-shaped profile of the support block 8. By inserting the support strut 1 into the slots 3 of the support blocks 8 and 9, the support blocks 8 and 9 are connected to each other, while the support struts 1 remain movable in the longitudinal direction. Finally, the support strut 1 secures the support blocks 8 and 9 to each other by means of the locking slots 4, which can be locked in the slots 3. Longitudinal movement of the support struts 1 is thus prevented. Fig. 6 It can further be seen that two support struts 1 are inserted together into the slots 3. The two support struts 1 are arranged such that both folded edges 12 are aligned with the support surface. However, it is also provided according to the invention that one of the support struts 1 can be inserted into the slot 3 in a 180° rotated form. As already mentioned, a particular advantage of the arrangement of the components 8, 9 of the support blocks is that the width of the support blocks can be determined as desired. Sufficiently large, flat components simply need to be used.

[0044] In the Fig. 7a This is a modular kit in the form of a bed, shown in perspective. The kit comprises three support trestles, each composed of parts 8 and 9, and 30 support struts 1, which are inserted into the slots 3 of the assembled support trestles 8 and 9. Each support strut has a folded edge 12, which faces the support surface. The folded support trestles 8 are also provided with a cover flap 13 to close the open top surfaces. The adjacent support struts 1 then form the support surface in the area of ​​the folded edges 12. Any object (not shown), such as a mattress on a bed, can then be placed on the support surface in the area of ​​the folded edges 12.

[0045] Fig. 7b is an exploded view of the subject of the Fig. 7a The exploded view shows the support struts 1 and the components 8, 9 of the support blocks. It is shown that the support blocks 8, 9 each consist of four flat components 8, 9. The components 8 are U-shaped and folded, allowing them to be stood upright. The respective components 9 are positioned next to the inner sides of the elongated side sections of the U-shaped components. A significant advantage of the respective support blocks 8, 9 is that the length of the support block formed from the components 8, 9 can be adjusted as desired. This makes it possible to produce any desired bed width. Only the number of support struts 1 to be inserted into the slots 3 needs to be selected. The bed width can therefore be, for example, 70 cm, 80 cm, 100 cm, 120 cm, 140 cm, 160 cm, 180 cm, 200 cm, and 250 cm. The same applies to the length of the bed.The support struts 1 have a length that ensures high stability. The length can be up to 150 cm or more, depending on the type of sheet material and the type of fold of the support strut 1. In this example, the length of the support strut is approximately 100 cm. By joining the support struts 1 together, a bed length of approximately 200 cm is created. In this example, the... Fig. 7a und Fig. 7b A bed with the usual standard dimensions of 180 cm width and 200 cm length is shown. Three support blocks 2 are used. Each support block 2 is made from two U-shaped folded support blocks 8 and two non-folded support blocks 9, as is partially shown in Fig. 6 The respective support struts 1 have locking slots 4 on their lower edge, i.e., the edge opposite the fold edge. The respective locking slots 4 of the support struts 1 secure the support struts 1 in the respective slots 3 of the support blocks 8, 9. This prevents the support struts 1 from being moved either longitudinally or transversely. The support struts 1 can therefore only be removed in the direction of the support surface, i.e., upwards.

[0046] In the Fig. 8a und 8b A perspective view of two support blocks in the form of a triangular prism 10 is shown. Fig. 8a shows the individual components and Fig. 8b the assembled components that constitute the finished piece of furniture. Fig. 8a The figure shows the slots 3 arranged accordingly on the upper surface of the triangular prism 10. The support struts 1 can be inserted into these slots 3 and are secured by the locking slots 4 located on the underside of the support struts 1. Once all the support struts 1 are inserted into the slots 3 of the triangular prism 10, a cover plate 11, for example, is placed on the upper surface of the support struts 1. The illustrated triangular prism 10 is a support stand which offers particular advantages. The prism-like design ensures stable support on a base. The support struts 1 can be inserted into the slots 3 located on the upper surface of the prism. The upper surface of the support struts 1 can then be fitted with any desired cover plate 11. It is clear that the height of the triangular prism can be determined as desired. This depends on the desired height of the usable surface on the upper surface.Thus, the kit can be designed as a table, a bench, a platform, or as a lounger or bed.

[0047] Fig. 9 Figure 1 represents a table composed of support blocks 2 and support struts 14, 15. The table's cover plate 11 is shown, but not yet placed on the assembled kit. The support struts 14, 15 form the support area for the cover plate 11 and are arranged such that 4-layer support struts 14 are located in the outer areas of the support surface and 2-layer support struts 15 are located in the inner area. It is clear that the components of the kit can be configured to form a table of any shape and size. The height of the tables can also be adjusted according to the... Figur 9 It can be designed in any way.

[0048] Fig. 10 The figure represents a platform composed of support blocks 2 and support struts 14, 15. The platform's cover plate 11 is shown, but not yet placed on the assembled kit. The support struts 14, 15 form the support area for the cover plate 11 and are arranged such that 4-layer support struts 14 are located in the outer areas of the support surface and 2-layer support struts 15 are located in the inner area. It is clear that the kit components can be configured to form a platform of any shape and size. The height of the platform can also be adjusted according to the figure. Figur 10 It can be designed in any way. This platform can also be designed in the form of a bench or a storage bench. The cover plate 11 can also be replaced by a cushion, seat, or upholstered pad.

[0049] Fig. 11 This represents another kit for a bed. Component 19 is a transversely foldable support block 19, which essentially corresponds to the previous support block 8. The support block 19 has two transverse fold marks 7, which fold the support block 19 transversely by approximately 90° to allow it to be securely erected. The support block 19 also has a cover flap 13, which can be arranged to cover the support strut 1, as is the case, for example, in... Fig. 12 is shown. Two elongated fold marks 6 are shown.

[0050] Furthermore, a longitudinally foldable support block 20 is shown, which, in contrast to component 9, has two support sides, whereby the support block 20 can also be set up securely by means of the longitudinal folding according to the elongated fold marks 6.

[0051] Other components are the support struts 1 with the corresponding locking slots 4, which can each be inserted into the slots 3 of the support blocks 19, 20.

[0052] Furthermore, connecting elements 18 are shown, which can, for example, lock two beds together, as in Fig. 13 These connecting elements are shown, comprising two elongated fold marks 6.

[0053] In the Fig. 12a und 12b A assembled bed kit is now shown in an exploded and perspective view. This view largely corresponds to the Figuren 7a und 7b The assembled kit comprises three assembled support blocks, each consisting of two cross-folded support blocks 19. Depending on the spacing of the support blocks 19, a corresponding number of support struts 1 are inserted into the slots of the support blocks 19. In contrast to the Figuren 7a und 7b The cover tabs 13 are arranged such that they overlap at least one support strut 1 and thus lock the support strut 1 in place. The cover tab 13 is therefore locked in the slot 3 of the second support strut 1. This results in the secure locking of the support struts 1 arranged on the outer sides of the bed. The width of the bed can be extended to any desired size by placing a longitudinally foldable support strut 20 between each of the two transversely foldable support blocks 19. In this case, only additional support struts 1 need to be added.

[0054] In the Fig. 13 is another variant of the assembled kit according to Fig. 12b Shown for a bed of any size. Fig. 13a shows two beds, like these in Fig. 12b are shown. If these two beds are to be joined together, connecting elements 18 can be inserted on the respective adjacent outer sides of the beds to be joined, as shown in Fig. 13b is shown. Fig. 13 c The securely assembled bed is now shown.

[0055] Fig. 14 This represents another kit for a table. Component 19 is a transversely foldable support block 19, which is essentially the same as the previous support block 2 according to Fig. 9 The support block 19 also includes folding marks 6, 7 which serve for longitudinal and transverse folding, respectively. The folding marks 7 serve to form the U-shape of the support block. Also shown is the support strut 1 with the corresponding locking slots 4 and the folding edge 12, which is formed after the approximately 180° fold. Furthermore, the Fig. 14 The tabletop 21 is shown. This tabletop 21 includes fold marks 6, fold edges 12, and locking slots 4. These locking slots 4 are formed only after the approximately 180° fold. In the subsequent fold mark 6, only the angle of approximately 90° is formed. This creates a support strut 1. The support struts 1 are then firmly locked to the tabletop 21. Due to this arrangement of the entire tabletop 21, it can be placed in the support block 19 or the further support blocks 2 and 10, as shown in the Fig. 8 , 9 und 10 depicted, to be locked.

[0056] In the Fig. 15a bis 15d The table's construction will now be shown. Fig. 15a Figure 1 illustrates the assembly of the two transversely foldable support blocks 19. The transverse fold initially secures each of the two transversely foldable support blocks with the cover flap 13. The side sections of the transversely folded support blocks 19 are then preferably fastened together using screws 22, washers 23, and nuts 24. The support blocks 19, thus secured, can now be locked with the support struts 1, as shown in Figure 2. Fig. 15b The detailed view clearly shows that only a two-sided support strut 1 is inserted into the slot 3 in the outermost area of ​​the support block 19. Fig. 15c This now represents the transformation of the tabletop 21. The tabletop 21 is also in the Fig. 14 The respective folded edges 12 are now arranged such that a support strut 1 is formed, which is firmly connected to the tabletop 21. The two tabletops 21 shown side by side are now placed into the support brackets as shown. Fig. 15b inserted, as is done in Fig. 15d As shown, since it is advantageous to always insert two support struts into the slots 3, one of the support struts 1 of the tabletop 21 is inserted into the outer slots and the other into the inner slot of the support block 19. This ensures a secure locking of the tabletop 21, as shown in the detail view.

[0057] In the Fig. 16a, 16b and Fig. 16c A assembled table kit is now shown in exploded and perspective views. According to Fig. 15a Two support trestles 19 are used to manufacture a table of a specific size. If a table is to be extended, at least one additional support trestle 19 is used. Further support struts 1 and additional tabletops 21 are placed on these support trestles 19, according to... Fig. 15c The components were designed and inserted into the support blocks 19. This makes it possible to produce tables of any length.

[0058] In the Fig. 17a und 17b The figures show dies which can be used for the production of the transversely foldable support blocks 19 and 25. Fig. 17a The symmetrically arranged support blocks 19 are shown, with the cover tabs 13 arranged directly next to each other. This has a disadvantage, as a considerable amount of material is not used when punching out the support blocks 19 and therefore has to be disposed of. In the Fig. 17b The cover tabs 13 are arranged side by side. This results in an asymmetrical arrangement of the support block 25. However, it is now possible to use less material to produce the same number of support blocks 19 and 25. Using less material conserves resources.

[0059] In the Fig. 18 With partial views 18a, 18b and 18c, the perspective view of the arrangement of the asymmetrical transversely foldable support blocks 25 is now shown. It can be seen that the arrangement of the respective support blocks is the same arrangement for setting up the bed in the Fig. 12a generated.

[0060] It is understood that the kits according to the present invention can be used to construct various furnishings such as furniture and the like. The support brackets are therefore designed at any desired height, allowing for the creation of various pieces of furniture. As already mentioned, these can be tables, stools, benches, loungers, beds, platforms, or any type of storage surface. A particular advantage of the present invention lies in the stability of the assembled components, namely the support brackets and the support struts inserted therein. Furthermore, no additional fasteners are required. Reference symbol list
