Description

[0001] The invention relates to a modular furniture system according to the preamble of claim 1.

[0002] Modular furniture systems are known in a wide variety of designs. They comprise a multitude of different furniture elements that can be assembled in various ways, resulting in furniture of different sizes, shapes, and uses.

[0003] In a basic version, the furniture elements have cuboid bodies, which themselves can be of different sizes. These bodies are equipped with coupling elements on their top and bottom surfaces, which prevent the stacked bodies from shifting against each other, thus creating a stable piece of furniture. The coupling elements on the top surfaces of the bodies are complementary to their counterparts on the bottom surfaces and can be detachably connected to them. In this way, identical bodies can be stacked on top of each other by connecting the coupling elements on the bottom of an upper body to the coupling elements on the top of a lower body.

[0004] The utility of such a modular furniture system is decisively determined by the number of possible combinations of the individual furniture elements, as well as by the fact that such combinations can be changed quickly and easily by the user. This flexibility is limited in furniture systems whose interconnected coupling elements can only be separated using a suitable tool. Furthermore, the furniture elements of known modular systems cannot be freely combined in any configuration.

[0005] It is therefore an object of the present invention to create a modular furniture system which offers a larger number of possible combinations of its furniture elements and thus almost unlimited variability, whereby the coupling of the individual furniture elements with each other can be carried out as simply as possible, without tools and without any manual skills.

[0006] This problem is solved according to the invention by a modular furniture system with the features of claim 1.

[0007] According to the invention, the surfaces of the undersides and the tops of the bodies each correspond to an integer number of square grid areas of the same size, arranged in a grid in the form of a matrix. This grid is translationally symmetric with respect to the arrangement of the coupling elements within the grid areas. The coupling elements are designed to be coupled by inserting the coupling elements into one another and then sliding them relative to each other.

[0008] The arrangement of the coupling elements in a regular, periodic grid allows stacked furniture elements to be coupled in various offset positions. For example, two identical furniture elements, each with two adjacent grid areas of equal size on its top and bottom surfaces, can be stacked either in a position precisely aligned, where the underside of the upper unit rests exactly on the top of the lower unit, or in a position offset by one grid unit, where the upper unit rests only halfway on the lower unit and the other half rests, for example, on a third furniture element immediately adjacent to the lower unit. This enables multiple furniture elements to be stacked on top of each other in a structured configuration.Such a structure can also be formed in a perpendicular direction according to the same principle. This matrix-like grid of the top and bottom surfaces of the units creates a high degree of variability, stimulating user creativity and practically inviting the creation of ever new stacking variations.

[0009] This is facilitated by the simplicity of the coupling devices used in the stacking process, which ensure the secure cohesion of the stacked furniture elements. These are complementary coupling elements that connect simply by inserting them into one another (a process that occurs automatically and effortlessly when the units to be stacked are placed on top of and aligned). The hold, i.e., the actual coupling of the units to each other, is achieved through a relative sliding movement of the two coupling elements (or the units that support them). This movement can be minimal, just a few millimeters, to create the necessary coupling and engagement of the coupling elements.In particular, lifting the upper furniture element from the lower furniture element on which it is stacked is no longer possible, nor is any lateral movement of the stacked furniture elements relative to each other, at least in most directions. However, it remains possible to detach the connecting elements to unpack the stack without tools.

[0010] Attaching the coupling elements to the top and bottom surfaces of the cabinets also offers the advantage that the coupling elements are no longer visible when the furniture elements are stacked. The external appearance of the resulting piece of furniture is not affected by the coupling elements.

[0011] Preferably, a coupling element is arranged centrally within each grid area. This offers the advantage that two furniture elements can be stacked in different rotational positions. This further increases the system's flexibility. It should be noted that the term "central" in this context is not to be understood as geometrically precise, but rather includes tolerances required due to the displacement necessary for coupling the complementary coupling elements.

[0012] Preferably, several coupling elements are arranged rotationally symmetrically within each grid area.

[0013] According to a further preferred embodiment of the present invention, each of two mutually complementary coupling elements comprises a male coupling element and a female coupling element, the male coupling element comprising an approximately mushroom-shaped head and the female coupling element being designed as a keyhole connector with an opening for inserting the head and an undercut cavity which adjoins the inner end of the opening laterally and into which the head, fully inserted into the opening, can be displaced in a direction perpendicular to the insertion direction.

[0014] This design of the complementary coupling elements allows them to be freely inserted into one another, while the lateral displacement of the mushroom-shaped head into the cavity secures the connection between the coupling elements. Lifting a furniture carcass that is coupled in this way and stacked on a lower furniture carcass is then no longer possible. Nevertheless, the coupling remains detachable by pushing the mushroom-shaped head back into the opening in the opposite direction, so that the head simply slides out of the opening when the upper carcass is lifted.

[0015] Preferably, the male coupling element is designed as a mushroom-head screw. In this case, the assembly of the male coupling element is particularly simple.

[0016] Preferably, the undercut cavity of the female coupling element has a constriction in the direction of movement, which the head of the male coupling element must pass through from the opening to reach the end of the cavity. This constriction prevents the mushroom head from accidentally sliding back into the opening and thus prevents accidental disconnection. A "click" effect can be achieved during coupling, providing the user with feedback that the connection is complete.

[0017] Preferably, the female coupling element is designed as a hammer-in sleeve. This sleeve can, for example, be made of plastic. This makes the assembly of the female coupling element particularly easy.

[0018] According to a further preferred embodiment of the invention, the circumferential contour of the sleeve is shaped such that the sleeve can be inserted into a space formed by two laterally overlapping circular bores. The receptacle for the sleeve can thus be easily produced by drilling two such bores. This avoids complex milling work on the furniture carcasses and allows the receptacle to be manufactured using a simple tool.

[0019] According to a further preferred embodiment, the bodies are provided with additional engagement elements on their undersides and tops, wherein the engagement elements arranged on the tops are complementary to the engagement elements arranged on the undersides, and the mutually complementary engagement elements can be used with lateral play when stacking two furniture elements by coupling their mutually complementary coupling elements.

[0020] These additional engagement elements can further secure the bodies against lateral slippage. The lateral play of the interlocking engagement elements allows the necessary shifting of the complementary coupling elements during the coupling process.

[0021] Preferably, the complementary engagement elements each comprise a pin and a hole for receiving the pin. If the pins are arranged on the undersides of the bodies, these can serve as feet when a body is placed on the floor.

[0022] Furthermore, the bodies are preferably provided with handle holes on their upper surfaces.

[0023] According to a further preferred embodiment of the present invention, at least one of the bodies contains a drawer, wherein the body comprises a transport lock for the drawer, which is formed by a recess in the top of the body, a bore in one end of the recess and an angled Allen key, one leg of which is inserted through the bore while the other leg is laid flat in the recess.

[0024] Once the drawer is inserted into the cabinet, the leg of the locking mechanism inserted through the hole acts as a stop, preventing the drawer from accidentally sliding out. The other leg can lie so flat in the recess that it is completely flush with the top of the cabinet and does not obstruct stacking of another cabinet on top. The recess for the transport lock can be milled into the top of the cabinet housing the drawer, while the hole is a through-hole extending into the interior of the cabinet, allowing the leg of the Allen key to be inserted through it.

[0025] Preferably, the recess for the transport safety device adjoins a handle hole.

Fig. 1 represents; and Fig. 7 and Fig. Figure 8 shows a perspective view and a top view of an alternative embodiment of such a sleeve.

[0027] Fig. Figure 1 shows a furniture element 10 comprising a cuboid body 12, which in the present embodiment has a square base. The in Fig. The visible upper surface 14 and the opposite (here concealed) lower surface are congruent and square. In this case, the furniture element 10 is designed to accommodate a drawer 16, the details of which are not shown, which can be pulled out laterally from the body 12.

[0028] The furniture element 10 shown here is one of a plurality of furniture elements of a modular furniture system, which can be combined with one another and, in particular, stacked on top of one another in various ways. For this purpose, the present furniture element 10 has features that are described in more detail below. This description is based on furniture element 10 as an example for other furniture elements of the modular furniture system according to the invention.

[0029] In the top view of the upper surface 14 of the furniture element 10 in Fig. 2 Four coupling elements are discernible, which protrude from the surface of the top surface 14 and shall be referred to below as male coupling elements 18 (shown here only schematically). Each of these four male coupling elements 18 is arranged in the center of a square grid area 20, one of which is in Fig. 2 is marked in the upper right. It is noted that this square grid area 20 is not an optically or physically marked area on the surface 14 of the corpus 12, but merely an imaginary geometric division of the surface. The surface 14 is composed of four such grid areas 20, which together form a grid in the form of a 2x2 matrix.

[0030] Such a grid area 20 is in Fig. 2A is shown schematically with its essential elements. These are the aforementioned male coupling element 18 in the center of the grid area and four holes 22 in the top surface 14, which are primary bores. The four holes 22 are arranged in the corner regions of the grid area 20. Fig. 2 it can be seen that each of the four grid areas 20 of the surface 14 is equipped with four such holes 22.

[0031] The top surface 14 of the body 12 is further equipped with handle holes 24, which are arranged approximately in the corner areas of the top surface 14 and serve to lift the body 12 and to facilitate transport. Towards the corners of the body 12, recesses 26 adjoin the handle holes 24. These recesses are milled outwards in the surface of the top surface 14; that is, the recesses 26 do not form complete openings in the top surface 14 of the body 12, but only extend partially into it.

[0032] At the ends of the recesses 26, which point towards the corners of the body 12, through holes 28 extend into the interior of the body 12. The surface-milled recesses 26, together with the holes 28, form transport locks for the drawer 16. The transport lock is completed by an angled Allen key (not shown), one leg of which is inserted vertically into the hole 28, while the other leg, angled at the end, lies flat in the recess 26. The leg inserted into the hole 28, which protrudes into the interior of the body 12, forms a lock for the back panel of the drawer 16 when installed and prevents the drawer 16 from accidentally sliding out.

[0033] It is noted that the transport securing device formed by the recess 26 and the bore 28 is useful for furniture elements 10 that accommodate a drawer 16, as shown in the present embodiment. The modular furniture system may include other furniture elements that do not include such a transport securing device.

[0034] In Fig. Figure 3 shows the underside 30 of the body 12 of the furniture element 10. Like the top side 14, the underside 30 of the body 12 is also provided with coupling elements, which are female coupling elements 32 that are complementary to the male coupling elements 18 on the top side 14 and can be detachably coupled to them. The female coupling elements 32 are thus designed to receive the male coupling elements 18 and are shown here only schematically in their positions. The coupling mechanism will be described in detail later.

[0035] The arrangement of the female coupling elements 32 on the surface of the underside 30 of the body 12 corresponds to the arrangement of the male coupling elements 18 within a grid in the form of a 2x2 matrix. The female coupling elements 32 are also each located in the center of a square grid area 20, the size of which exactly corresponds to the grid areas 20 of the top side 14. Fig. 2 and Fig. 2A corresponds to this.

[0036] Such a grid surface 20 of the underside 30 is in Fig. 3A is shown in more detail in its essential elements. Besides the female coupling element 32, it comprises three pins 34 in three corner areas of the grid surface 20, the diameter of which is smaller than that of the holes 22 on the top surface 14.

[0037] Also in Fig. Figure 3 shows only the upper left grid area 20 graphically. The entire area of ​​the bottom surface 30 is formed by four such grid areas 20 arranged in a 2x2 matrix. It should be noted that the three remaining (not graphically shown) grid areas 20 differ from grid area 20 in Fig. 3A, are equipped with different arrangements of pins 34. The arrangement of the pins 34 can therefore vary in the respective grid areas 20 on the underside 30.

[0038] The respective grids on the top surfaces 14 and the bottom surfaces 30 of the bodies 12 are translationally symmetric with respect to the arrangement of the coupling elements within the grid areas 20. This means that the position of one coupling element within the grid area 20 can be transformed into the position of another coupling element by a lateral displacement of at least one grid position. This means, for example, with regard to the top surface 14 in Fig. 2, that the position of the upper left male coupling element 18 can be shifted to the right by moving the grid area 20, in the center of which this male coupling element 18 is located, to the position of the upper right coupling element 18, which is located in the center of the adjacent grid area 20 shown. The same applies to a shift downwards by one grid position, as well as to a shift downwards by one grid position to the position of the lower right coupling element 18.

[0039] The top surface 14 is thus composed of an integer number of square grid areas 20 of the same size, whose grid area 20 can be transformed into one another by lateral periodic shifts.

[0040] The same applies to the grid areas 20 of the underside 30 of the body 12, which are also formed from four square grid areas 20 of the same size. The position of the upper left female coupling element 32 can be shifted to the position of the upper right female coupling element 32 by moving it one grid position to the right (i.e., by one complete grid area 20), and so on.

[0041] Furthermore, this shift can be continued by another furniture element 10 (not shown), which is attached laterally to, for example, the existing element. Fig. 2 furniture element 10 is attached, thus extending the grid laterally adjacent to its top 14.

[0042] In contrast to the embodiment of furniture element 10 shown here, the present modular furniture system can include further furniture elements of different sizes, in particular larger furniture elements whose undersides and tops of the carcasses 12 are again composed of an integer number of square grid areas 20 of the same size, for example in a 3x2 grid, a 4x2 grid, and so on. A 1x2 grid is also conceivable, as is a furniture element whose undersides 30 and tops 14 of its carcass 12 correspond to a single square grid area 20.

[0043] These furniture elements can be stacked on top of each other by coupling the complementary male and female coupling elements 18, 32 together, thereby aligning the grid surfaces 20 of the stacked furniture elements 10 with each other. The stacking thus takes place according to the grid.

[0044] For example, if two furniture elements 10 have identical bodies 12 as in Fig. As shown in Figure 1, the male coupling elements 18 are stacked on top of each other, aligned with the female coupling elements 32 so that they can slide vertically into one another and then be shifted laterally relative to each other. This shift can be minimal compared to the overall size of the cabinets 12, for example, by just a few millimeters. In the final coupling position, a grid surface 20 of the underside 30 of the upper furniture element 10 rests exactly on a grid surface 20 of the top surface 14 of the cabinet 12 of the lower furniture element. This applies to all four grid surfaces 20 on both the top surface 14 and the underside 30 of the stacked cabinets 12. In the stacked state, the vertical outer walls of the stacked cabinets 12 are then flush with each other.

[0045] Alternatively, a staggered stacking arrangement is conceivable, as is the case, for example, in Fig. Figure 4 shows two adjacent furniture elements 10. Fig. 1, which lie against each other on two outer walls. On their upper surfaces 14, another identical furniture element 10 is stacked centrally and in a staggered arrangement, so that it rests on both lower furniture elements 10 with equal surface areas, namely such that its two left grid surfaces 20 on its underside 30 lie on two right grid surfaces 20 of the upper surface 14 of the left lower furniture element 10 and are congruent with them, while its two right grid surfaces 20 on its underside 30 lie on the two left grid surfaces 20 of the upper surface 14 of the lower right furniture element 10. The complementary coupling elements 18, 32 on the grid surfaces 20 thus aligned engage with each other and ensure a connection of the three furniture elements 10 shown.

[0046] This coupling principle according to a translationally symmetric grid can be extended arbitrarily by different sizes of furniture elements 10, as already shown, or in the plane in which a layer of furniture elements 10 is formed, which are placed laterally opposite each other in two mutually perpendicular spatial directions, so that furniture elements 10 stacked on top of it in another plane can be coupled within the grid in different grid positions.

[0047] Fig. Figure 4A shows a male coupling element 18, which is designed as a mushroom-head screw. Its front part is designed as a threaded shaft 70, to which a shaft 72 of smaller diameter and the actual mushroom head 74, which has a larger diameter than the shaft 72, are connected. At the transition from the shaft 72 to the threaded shaft 70, a radially extended plate area 76 with a larger diameter than the mushroom head 74 is provided.

[0048] The mushroom-head screw 18 is mounted by simply screwing the threaded shaft 70 into the material of the top surface 14 of the body 12 until the plate area 76 abuts it or is slightly pressed into the top surface 14. The shaft 72 and the mushroom head 74 then protrude freely on the top surface 14.

[0049] Fig. 5 and Fig. Figure 6 shows an embodiment of a female coupling element 32, as used on the undersides 30 of the bodies 12 of the furniture elements 10 according to the embodiment described above. This female coupling element 32 is a sleeve constructed like a keyhole connector and includes a freely accessible opening 40 for inserting the mushroom head 74 of the male coupling element 18. Fig. 4A and an undercut cavity 42, which adjoins the opening 40 laterally (i.e., in a direction parallel to the plane of extension of the underside 30 of the body 12). The term "undercut" here means that the cavity 42 is open in the same direction as the opening 40, but has a downwardly widening diameter, in this case thus having an approximately T-shaped cross-section, which is approximately complementary to the shape of the shaft 72 and the mushroom head 74 of the male coupling element 18.

[0050] The diameter of the opening 40 is large enough to allow the mushroom head 74 to be inserted vertically. The mushroom head 74 can then be inserted laterally into the cavity 42, the lateral diameter of which corresponds to the underside of the female coupling element 32, which is located in the Fig. 5 and Fig. 6 is located at the top, so small that although the shaft 72 fits in, the mushroom head 74 can no longer be pulled out in a direction opposite to the insertion direction.

[0051] This position corresponds to the coupling position of two stacked bodies 12. The upper body 12 can then no longer be lifted by the lower body 12, and lateral movement is only possible to a limited extent, namely in the direction in which the mushroom head 74 slides out of the cavity 42 towards the opening 40 (i.e., in the illustration in Fig. 6 downwards).

[0052] The opening 40 and the undercut cavity 42 lie within a surface area 44 of the female coupling element 32, which is stepped on the inside, i.e., slightly recessed towards the inside of the female coupling element 32. The step is provided with chamfers 46 around the circumference of the opening 40, and the edge of the opening 40 itself is provided with a bevel 48. The chamfers 46 and the bevel 48 facilitate the insertion of the mushroom head 74.

[0053] Overall, the female coupling element 32 is designed as a drive-in sleeve made of a plastic material. Its circumferential contour 50 is shaped such that the sleeve can be inserted or driven into a space formed by two laterally overlapping circular bores. This is, for example, Fig. 3A is indicated. A portion of the female coupling element 32, which encompasses the larger part of the opening 40, corresponds to the partial circumference of a cylinder. An adjoining portion, in which the cavity 42 is arranged, is similarly shaped but has a flattened end face 54.

[0054] The circumferential surfaces of the sleeve, which correspond to the outer partial circumferential surfaces of a cylinder, are in contact with the inner walls of the overlapping circular bores when inserted and are equipped with impact ribs 56 that prevent the female coupling element 32 from falling out of the space formed by the laterally overlapping circular bores.

[0055] Fig. 7 and Fig. Figure 8 shows an alternative embodiment of a female coupling element 32a, which is a derivative of the female coupling element 32 of the previous embodiment. Fig. 5 and Fig. 6 corresponds, with only a few deviations, which are described below. Elements that correspond to those from the Fig. 5 and Fig. The elements corresponding to 6 are subsequently referred to with the same reference symbols. The following description focuses on the differences between the two female coupling elements 32 and 32a.

[0056] The female coupling element 32a is also essentially designed as a sleeve in the form of a keyhole connector. An undercut cavity 42a adjoins the opening 40 laterally. Its free opening area on the upper side of the female coupling element 32a, which serves to guide the shaft 72, has a constriction 60 in the area connecting to the opening 40. The shaft 72 must pass through this constriction to reach the end of the undercut cavity 42 furthest from the opening 40 and thus the final coupling position. The constriction 60 therefore provides resistance to prevent the mushroom head 74 from sliding back out of the cavity 42a towards the opening 40.

[0057] In the area of ​​the constriction 60, the lateral walls of the opening area of ​​the cavity 42a can be resiliently pushed apart, thus allowing the shaft of the mushroom head 74 to slide through. This resilient arrangement of the side walls 62 is made possible by recesses between the side walls 62 and the surrounding part of the body of the sleeve 32a.
