[0042] In the sense of the invention the kit consists of at least one bearing trestle and at least two bearing struts, wherein the bearing struts are insertable in at least one slot in the upper area of the bearing trestle.
[0043] The components used according to the present invention are formed from laminar foldable materials. These materials can consist of cardboard, corrugated cardboard, carton, plastic, metal, textile fabric or of composite materials of said materials. Especially preferred are materials wherein the components have a protective layer, selected from water-repellant and/or fire-retardant materials and/or a have a decorative layer, selected from paints, films, varnishes, textiles and/or flockings.
[0044] Advantageous according to the invention are the laminar foldable materials made of corrugated cardboard, which have double flutes. These double flutes, also called duplex or corrugated cardboards with combined flutes, have an outer layer, a below arranged flute with a small distance to the adjacent flute and relatively little height, there below an intermediate ceiling, then a below arranged wide flute with a greater distance and greater height than the above arranged flute, as well as the inner ceiling arranged at the lower side. The herewith described double flute corrugated cardboard, also called BC-flute is especially advantageous, since the bearing struts that need to be fabricated for the 180 folding do not destroy or tear the outer layer when the fold edge during the folding is formed in direction of the outer ceiling of the corrugated card board. A smooth surface is formed which can be used as bearing surface for further components.
[0045] The laminar components namely the bearing trestles and the bearing struts have a length and a width and thus have a longitudinal direction and a transverse direction. Folding marks which are arranged in the longitudinal direction, i.e. along the length of the components or in the transverse direction, i.e. along the width of the components, can be positioned on these components. Thus, folding marks can be arranged on the bearing trestles and on the bearing struts in any desired manner and in any number in the longitudinal direction and/or in the transverse direction. During the assembly of the items of furniture that can be fabricated, the components are then folded along the respective folding marks and inserted into one another accordingly.
[0046] The bearing trestle is the component according to the present invention, which can be placed on the floor, for example. The bearing trestle has an upper region and a lower region. The lower region is the region resting on the floor. The term upper region in the bearing trestle is defined in such a way that the bearing trestle, for securing the components to be placed, can be erected on a flat surface and thus the upper region is spaced apart from the lower region. The upper region of the bearing trestles is furthermore defined as bearing area. In the upper region, what means in the bearing area, of the bearing trestle slots for receiving the bearing struts are arranged in any number. The slots are advantageously arranged at equal distances from one another in order to optimize the possibility of introducing the bearing struts.
[0047] The bearing trestle can have any desired geometric shapes. Preferably bearing trestles are described that are in the form of a cuboid or a triangular prism.
[0048] According to the invention, however, other bearing trestles can also be used as components of the kit according to the invention. What is decisive here is that in the bearing area slots for receiving and optionally for locking of the bearing struts are provided.
[0049] Here it is preferred that the cuboid bearing trestle can be assembled from a plurality of components. The individual laminar components have, for example, folding marks in the transverse direction, so that the components can be folded in a U-shape in order to form a bearing trestle, wherein the components are then each folded at 90.
[0050] These U-shaped components, namely the bearing trestles, have particular advantages. Because of the parallel arrangement of the two side parts for receiving the bearing struts it is provided according to the invention to arrange the bearing struts only halfway between the parallel side parts. In this way the items of furniture can be erected in extended form. It is therefore possible to use any number of U-shaped bearing trestles as desired. This is very advantageous, for example, for tables, bench seats or pedestals.
[0051] It is furthermore intended according to the invention to increase the width of the U-shaped bearing trestles. To this end advantageously at least one bearing trestle is used that can be folded longitudinally. The two previously erected U-shaped, transversely folded bearing trestles are then displaced from one another and then the longitudinally foldable bearing trestle or else the non-folded bearing trestles are arranged in such a way that the slots of the bearing trestles arranged one behind the other are locked with the bearing struts. These arrangements described herein are to be seen in the accompanying figures and are described herein accordingly.
[0052] The bearing struts according to the invention disclosed herein have at least one folding mark arranged in the longitudinal direction. This folding mark serves to fold the bearing strut into a 2-layered, 3-layered, 4-layered or multilayered embodiment. In this case, it is provided that the fold has a bend of almost 180. The folded bearing strut is then inserted into the slots of the bearing trestles. The advantage here is that the folded surfaces of the bearing struts do not have to be fastened or even glued to one another or to other components.
[0053] The insertion into the slots of the bearing trestles ensures a fixing in the slots, since a pressure is produced along the folding and thus counteracts a restoring force of the folding. A further advantage of the bearing struts according to the invention is that a smooth folding edge is formed. This smooth folding edge on the upper side is the bearing surface of the assembled kit and therefore does not damage the components that can be placed or are placed like mattresses, cover plates, cushions and the like. Furthermore, according to the invention it is provided that on the lower side of the bearing struts locking slots are arranged that can be locked in the bearing trestles. This ensures that the bearing struts cannot be moved in the longitudinal direction without them being removed from the slots, because this would lead to a problem concerning stability of the assembled kit.
[0054] The components assembled in such a way cause a high stability and advantageously also a simple assembly of the items of furniture. The subsequent disassembly of the items of furniture is also simple since no tools are required. For example, defective components can also be replaced or exchanged in a simple manner.
[0055] In summary, it can be noticed that the kits of the present invention allow intermediate spaces to be bridged in a preferred manner, for example, with corrugated cardboard, without further stabilizations being required. For this purpose, the bearing struts according to the invention are provided, which are discussed in more detail below.
[0056] The combination of the components according to the invention allows to provide items of furniture which are variable in length, height and width. In respect of their design, that means the optical impression and the functionality, the fabricated items of furniture are comparable with furniture that is known culturally. Furthermore, it is an essential factor that, although the items of furniture are made of materials that are sustainable, they are nevertheless suitable for long-lasting use.
[0057] The surprising stability, steadiness and durability of the items of furniture according to the invention were acknowledged to the applicant by an accredited test center for positively passing the assessments according to the standards DIN EN 12521:2015, DIN EN 1730:2012, DIN EN 1725:2018 and DIN EN 10 1022:2019.
[0058] The following examples illustrate the invention in more detail without limiting the scope of the invention. The present invention is explained in more detail below with reference to FIG. 1 to FIG. 18.
[0059] FIG. 1 shows several views of the bearing strut 1 according to the invention. FIG. 1a is a cross-sectional view of the bearing strut 1. The bearing strut 1 consists of a laminar material which preferably has at least one folding mark 6, along which the laminar material is folded by up to 180 and thereby forms the bearing strut 1. The fold edge 12 thus formed has a curved surface, which is advantageous, since no edges are formed on the side of the bearing area of the assembled kit. In FIG. 1b the bearing strut 1 is shown in a perspective view and in FIG. 1c as side view. In these FIGS. 1b and 1c the locking slots 4 are shown, which can be latched into the slots 3 of the bearing trestles 2, 8, 9, 10, 19, 20. The arrangement of the locking slots 4 in the bearing struts 1 is advantageously selected in such a way, that the locking slots 4 can be latched into the U-shaped bearing trestles 9, 19, in order to fix the U-shaped profile thereof. The spacing of the locking slots 4 is therefore selected in such a way that their distance corresponds to the distance of the side parts of the U-shaped profile during assembly of the bearing trestle. Only one locking slot 4 is introduced on the opposite side of the bearing strut 1, since, for example, when several bearing trestles 8, 9, 19, 20 are used, the bearing strut 1 must only be insertable in one side part of the U-shaped profile 8, 19. However, it is clear that when only two bearing trestles 8, 19 are used, at least four locking slots 4 are introduced in a corresponding arrangement on the underside of the bearing strut 1. This is shown, for example, in FIG. 14 for the bearing strut 1 shown there with four locking slots 4. Four locking slots 4 are required when the bearing struts are to be arranged only on two bearing trestles. However, it is also possible to arrange in each case four locking slots 4 in the respective bearing struts 1, even if these bearing struts are to be arranged in several bearing trestles.
[0060] FIG. 2 is a cross-sectional view of bearing strut 1, which is formed of corrugated cardboard. The fold mark 6 formed in longitudinal direction of bearing strut 1 is formed opposite to fold edge 12. Then, along fold mark 6 the bearing strut is folded. Fold edge 12 forms the bearing area of bearing strut 1.
[0061] It is shown that the fold edge is formed in an arc-shaped manner, whereby a smooth surface is formed. This smooth surface has the advantage that objects that are deposited thereon, such as mattresses or cover plates, are easily displaceable and whereby the surfaces of the displaceable objects are not damaged.
[0062] It is particularly advantageous (not shown) if the corrugated cardboard has two different sides. The side oriented at the fold edge 12 is formed with finer flutes, while the side opposite the fold edge 12 is formed with wider flutes. This leads to the fold edge 12 advantageously not being torn open during folding.
[0063] In FIG. 3 cross-sectional views of different embodiments of the folded bearing struts 14, 15 are illustrated. FIG. 3a shows a simple V-fold and thus forms a two-layer bearing strut 15, wherein the bend along the fold mark is approximately 180. FIG. 3b shows the parallel arrangement of two 2-layer bearing struts 15, wherein the fold edges are each aligned to the upper side. FIG. 3c shows a concertina-like fold, wherein a 3-layer bearing strut 17 is configured. In FIG. 3d a 4-layer bearing strut 14 is shown, which is configured in form of a double gate fold, which can be also designated as eight-sided window fold. FIG. 3e shows a 4-layer bearing strut 14 in form of a double parallel fold. The variant of bearing strut of FIG. 3e is characterized in that the upper edge of the bearing strut 14 does not have a gap. FIG. 3f shows a 4-layer bearing strut 14, which is designed in the form of a variant of the concertina fold, which is referred to as Swiss-fold. FIG. 3g shows a further concertina fold, which forms a 4-layer bearing strut 14. The variants of the bearing struts 14, 15, 17 shown in FIG. 3 represent fold variants known per se. It is clear that apart from the 2-, 3-, and 4-layer bearing struts 14, 15, 17 also bearing struts with any number of layers can be formed.
[0064] In FIG. 4 a perspective view of the cross folded bearing strut 16 is shown. FIG. 4a shows the laminar arrangement of the not yet folded bearing strut 16. This bearing strut 16 has a fold mark 6 being arranged centrally in longitudinal direction and a fold mark 7 being centrally arranged in transverse direction. FIG. 4b shows that the rear part of bearing strut 16 is folded along the transversely arranged folding mark 7. In FIG. 4c the folding along fold mark 7 to almost 180 is shown. FIG. 4d now shows the further folding of bearing strut 16 along fold mark 6 arranged in longitudinal direction, wherein the fold edges 12 along bearing strut 16 are shown. It is clear that because of the cross-foldlike arrangement of the bearing strut 16 in the area of the folding mark 7 no open surfaces are formed at the fold edges. This has the advantage that smooth and curved surfaces are thus formed on the end sides of the bearing struts 16. This is particularly advantageous with the kit shown in FIGS. 7a and 7b but can also be used for all further kits according to the present invention.
[0065] In FIG. 5 a perspective view of the arrangement of two bearing trestles 8 is shown. FIG. 5a shows the components of the 2-layer bearing strut 15 and of the bearing trestles 8 in an arrangement where they are separate from one another. FIG. 5b shows the arrangement of the bearing trestles 8 in an arrangement displaced into one another. This arrangement can be designed as desired. The U-shaped configuration of the bearing trestles 8 makes it possible to arrange a component 8 in the inner sides of the other component 8, or in each case to arrange one side of the component 8 on the outside of the other component 8. In FIG. 5c finally the insertion of the supporting strut 15 into the slots 3 of the assembled bearing trestles 8 is shown. The bearing strut 15 shown in this FIG. 5c is 2-layered and the fold edge 12 is oriented towards the bearing surface.
[0066] In FIG. 6 a perspective view of the arrangement of the bearing trestles 8, 9 and of the bearing strut 1, as well as a detailed view of the connection of these components is shown. This view substantially corresponds to the example of FIG. 7b. The U-shaped bearing trestle 8 has furthermore a cover flap 13. This cover flap 13 advantageously fixes the U-shaped arrangement of the bearing trestle 8. Components 9 are inserted into the inner sides of the U-shaped profile of the bearing trestle 8, which are designed to be laminar. By inserting the bearing strut 1 into the slots 3 of the bearing trestles 8, 9, the bearing trestles 8, 9 are interconnected, whereby the bearing struts 1, however, are still moveable in the longitudinal direction. Finally, the bearing strut 1 fixes the bearing trestles 8, 9 to one another by means of the locking slots 4, which can be locked in the slots 3. A movement of the bearing struts 1 in longitudinal direction is thus avoided. In FIG. 6 it can be furthermore derived that two bearing struts 1 together are inserted into the slots 3. The two bearing struts 1 are arranged in such a way that both fold edges 12 are aligned with respect to the bearing surface. However, according to the invention, it is also provided that one of the bearing struts 1, in a shape turned by 180, can be inserted into slot 3. As already mentioned, it can be considered to be a particular advantage of the arrangement of the components 8, 9 of the bearing trestles that the width of the bearing trestles can be chosen as desired. Only sufficiently large laminar components have to be used.
[0067] In FIG. 7a an assembled kit in form of a bed is shown in perspective. The assembled kit comprises three bearing trestles, each assembled from 8 and 9, and 30 bearing struts 1, which are inserted into the slots 3 of the assembled bearing trestles 8, 9. The bearing struts each have a fold edge 12, which are aligned in respect of the bearing surface. The bearing trestles 8, which are each folded, further have a cover flap 13, in order to close the open upper sides of the bearing trestles 8. The bearing struts 1 that are inserted side by side then form the bearing surface in the area of the fold edges 12. On the bearing surface in the area of the fold edges 12 any object (not shown) can be placed, like for example a mattress on a bed.
[0068] FIG. 7b is an exploded view of the object of FIG. 7a. The exploded view shows the bearing struts 1 and the components 8, 9 of the bearing trestles. It is shown that each of the bearing trestles 8, 9 consists of four laminar components 8, 9. The components 8 are folded in U-shape and therefore can be set up. The respective components 9 are arranged beside the inner sides of the elongated side parts of the U-shaped components. An essential advantage of the respective bearing trestles 8, 9 is that the length of the bearing trestle formed by the components 8, 9 can be arranged as desired. Thereby, it is possible to prepare any width of the bed. Only the number of the bearing struts 1 that are to be inserted into the slots 3 must be selected. Thus, the width of the bed can be for example 70 cm, 80 cm, 100 cm, 120 cm, 140 cm, 160 cm, 180 cm, 200 cm and 250 cm. The same also applies to the length of the bed. The bearing struts 1 have a length that guarantees a high stability. The length can be up to 150 cm or more, depending on the kind of the laminar material and of the kind of the folding of the bearing strut 1. In the present example the length of the bearing strut is about 100 cm. Thus, by apposition of the bearing struts 1 a bed length of about 200 cm is formed. In the present example of FIG. 7a and FIG. 7b a bed with the common standard dimensions of 180 cm in width and 200 cm in length is shown. In this case, 3 bearing trestles 2 are now used. Each bearing trestle 2 is produced from two bearing trestles 8 folded in U-shape and from two not folded bearing trestles 9, as this is partially shown in FIG. 6. The respective bearing struts 1 have locking slots 4 on the lower edge, that is the edge opposing the fold edge. With the respective locking slots 4 of the bearing struts 1 the bearing struts 1 are fixed in the respective slots 3 of the bearing trestles 8, 9. This causes that the bearing struts 1 cannot be moved, neither in longitudinal direction nor in transverse direction. Thus, the bearing struts 1 can only be removed in the direction of the bearing surface, that is to say upwards.
[0069] In the FIGS. 8a and 8b a perspective view of two bearing trestles in form of a triangular prism 10 is shown. FIG. 8a shows the individual components and FIG. 8b the assembled components, which show the completed item of furniture. FIG. 8a shows the slots 3 that are arranged correspondingly on the upper side of the triangular prism 10. The bearing struts 1 can be inserted into these slots 3 and are fixed by the locking slots 4 arranged at the lower side of the bearing struts 1. When all bearing struts 1 are inserted into the slots 3 of the triangular prism 10, then, on the upper side of the bearing struts 1 for example a cover plate 11 is placed. The shown triangular prism 10 is a bearing trestle, which has special advantages. The prism-like configuration achieves a stable bearing on a floor surface. The bearing struts 1 can be inserted into the slots 3 arranged in the upper region of the prism. The upper side of the bearing struts 1 can then be equipped with any cover plate 11. It is clear that the height of the triangular prism can be formed in any desired way. This is dependent on the height on which the usable surface shall be provided on the upper side. Thus, the kit can be configured as table, as pedestal, or as couch or bed.
[0070] FIG. 9 shows a table assembled from bearing trestles 2 and bearing struts 14, 15. The cover plate 11 of the table is shown, but not yet positioned on the assembled kit. The bearing struts 14, 15 form the bearing area for the cover plate 11, and are there arranged in such a way that in the outer areas of the bearing surface 4-layered bearing struts 14 and in the inner area of the bearing surface 2-layered bearing struts 15 are arranged. It is clear that the components of the kit for constructing a table can be designed in any form and dimension. Also, the height of the table according to FIG. 9 can be built in any desired manner.
[0071] FIG. 10 shows a pedestal assembled by bearing trestles 2 and bearing struts 14, 15. The cover plate 11 of the pedestal is shown, but not yet placed on the assembled kit. The bearing struts 14, 15 form the bearing area for the cover plate 11, and are there arranged in such a way that in the outer areas of the bearing surface 4-layered bearing struts 14 and in the inner area of the bearing surface 2-layered bearing struts 15 are arranged. It is clear that the components of the kit for constructing a pedestal can be designed in any form and dimension. Also, the height of the pedestal according to FIG. 10 can be built in any desired manner. However, this pedestal can also be designed in form of a seat bench or a deposition bench. The cover plate 11 can also be replaced by a pillow, seat surfaces or a padding cushion.
[0072] FIG. 11 shows a further kit for a bed. Component 19 is a transversely foldable bearing trestle 19, which substantially corresponds to the previous bearing trestle 8. The bearing trestle 19 has two transverse folding marks 7, each transversely folding the bearing trestle 19 by about ca. 90, in order to allow the bearing trestle 19 to be safely erected. The bearing trestle 19 furthermore has a cover flap 13, which can be arranged in such a way for covering that the bearing strut 1 can be fixed, as for example shown in FIG. 12. Here, two longish folding marks are shown.
[0073] Furthermore, a longitudinally foldable bearing trestle 20 is shown, which, in the contrary to component 9, has two bearing sides wherein because of the longitudinal folding according to the longish fold marks 6 the bearing trestle 20 too is securely erectable.
[0074] Further components are the bearing struts 1 with the respective locking slots 4, which in each case can be inserted into the slots 3 of the bearing trestles 19, 20.
[0075] Furthermore, connecting elements 18 are shown, which can for example lock two beds together as shown in FIG. 13. These connecting elements comprise two longish fold marks 6.
[0076] In the FIGS. 12a and 12b now an assembled kit of a bed is illustrated in exploded and perspective view. This view also corresponds in essential parts to FIGS. 7a and 7b. The assembled kit comprises three assembled bearing trestles, each consisting of two transversally folded bearing trestles 19. Depending on the distance of the bearing trestles 19 a respective number of bearing struts 1 is inserted into slots of the bearing trestles 19. In the contrary to FIGS. 7a and 7b the cover flaps 13 are arranged in such a way that they overlap at least one bearing strut 1 and thus lock the bearing strut 1. The cover flap 13 is thus locked in slot 3 of the second bearing strut 1. This leads to a secure locking of the bearing struts 1 each arranged on the outer sides of the bed. The width of the bed can still be enlarged in any size if a longitudinally foldable bearing trestle 20 is arranged between each of the both transversely foldable bearing trestles 19. Then, additionally only further bearing struts 1 have to be arranged.
[0077] In FIG. 13 a further variant of the assembled kit according to FIG. 12b for a bed as large as desired is illustrated. FIG. 13a shows two beds as shown in FIG. 12b. If the two beds are now to be interconnected, then connecting elements 18 can be inserted on the respective adjoined positioned outer sides of the beds to be assembled as shown in FIG. 13b. FIG. 13 c now shows the securely joined bed.
[0078] FIG. 14 illustrates a further kit for a table. Component 19 is a transversely foldable bearing trestle 19, which substantially corresponds to the previous bearing trestle 2 according to FIG. 9. The bearing trestle 19 further comprises folding marks 6, 7 which serve for longitudinal or transverse folding, respectively. The folding marks 7 serve for the U-shaped construction of the bearing trestle. Further illustrated is the bearing strut 1 with the respective locking slots 4 and fold edge 12, which is formed after the folding of about 180. Furthermore, in FIG. 14 the table top 21 is illustrated. This table top 21 comprises folding marks 6, fold edges 12, and locking slots 4. These locking slots 4 are formed after the folding of about 180. Only the angle of about ca. 90 is then formed in the further folding mark 6. Thereby, this arrangement is formed into a bearing strut 1. The bearing struts 1 are then firmly locked with the table top 21. This arrangement of the complete table top 21 allows the said to be locked in bearing trestle 19 or in the further bearing trestles 2 and 10, as illustrated in FIGS. 8, 9, and 10.
[0079] In the FIGS. 15a to 15d now the construction of the table is illustrated. FIG. 15a illustrates the assembly of the both transversely foldable bearing trestles 19. First, by the transverse folding each of the two transversely foldable bearing trestles are locked by the cover flap 13. The side regions of the transversely folded bearing trestles 19 are then preferably locked to one another by means of screws 22, washers 23, and nuts 24. The bearing trestles 19 fixed in that way can now be locked with the bearing struts 1, as this is illustrated in FIG. 15b. In the detailed view it can be clearly seen that at the slot 3 in the outmost region of the outer side of the bearing trestle 19 only a double-sided bearing strut 1 is inserted. FIG. 15c now illustrates the transformation of the table top 21. The table top 21 is also illustrated in FIG. 14 accordingly. The respective folding marks 12 are now arranged in such a way that a bearing strut 1 is formed, which is firmly connected with table top 21. The two table tops 21 shown side by side are now inserted into the bearing trestles according to FIG. 15b, as illustrated in FIG. 15d. Because advantageously always two bearing struts are inserted into the slots 3 one of the bearing struts 1 of the table top 21 is inserted into the outer slots and the other into the inner slot of the bearing trestle 19. Thereby, a secure locking of the table top 21 is reached as illustrated in the detailed view.
[0080] Now in FIG. 16a, 16b and FIG. 16c an assembled kit of a table is illustrated in an exploded and perspective view. According to FIG. 15a two bearing trestles 19 are used to fabricate a table of a certain size. If a table is now to be elongated at least a further bearing trestle 19 is used. Placed on these bearing trestles 19 further bearing struts 1 and further table tops 21, which were constructed according to FIG. 15c, are inserted into the bearing trestles 19. Thereby it is possible to produce arbitrary long tables.
[0081] In FIGS. 17a and 17b punching tools are illustrated, which are useable for the fabrication of the transversally foldable bearing trestles 19 and 25. In FIG. 17a the symmetrically arranged bearing trestles 19 are shown, wherein the cover flaps 13 are arranged directly side by side. This has a disadvantage, because during the punching of the bearing trestles 19 a number of material is not used and thus must be disposed. In the FIG. 17b the cover flaps 13 are arranged side by side. This leads to an asymmetrical arrangement of the bearing trestle 25. However, it is now possible to use less material to produce the same number of the bearing trestles 19, 25. Using less material saves resources.
[0082] In the FIG. 18, with the partial views 18a, 18b, and 18c, now the perspective view of the arrangement of the asymmetrically transverse foldable bearing trestles 25 is illustrated. It becomes apparent that the arrangement of the respective bearing trestles generates the same arrangement for the set-up of the bed in the FIG. 12a.
[0083] It shall be understood that the kits according to the present invention can form different items of equipment like furniture and the like. The bearing trestles are therefore provided in any height, so that different items of furniture can be designed. As already mentioned, these can be tables, stools, seat benches, lying benches, beds, pedestals, or any storage surface. A particular advantage of the present invention lies in the stability of the assembled components, namely of the bearing trestles and the bearing struts inserted therein. Further, no additional fastening parts are needed.
