Preferably the furniture has a modular construction and the walling element can be attached and removed as required, especially by hand.

Description

Technical area

The invention relates to a piece of furniture having at least one frame-shaped, structuring framework which is designed such that a surface filling element for filling a region of a wall of the furniture defined by the frame can be fastened to the frame. Furthermore, the invention relates to a Flächenfüllelement for such furniture, with a base plate made of a solid material and at least one fastening element for attachment to a frame-shaped, structural framework of the furniture.

State of the art

Furniture is typically purchased at a particular time, with care generally taken to ensure that the furniture purchased satisfies the most important needs of the user at that time. But furniture is not only subject to fashionable trends like many other everyday objects, but also the needs of users can change over time. Ie. There is a need for furniture that can be easily, quickly and inexpensively adapted to the changing needs of users. In order to be able to change the shape and size of furniture, there have been furniture for quite some time, which are modular and can be adapted to new needs, for example, by adding, removing or replacing modules.

Next furniture are known which have a structure-providing framework, which consists for example of a plurality of interconnected rods. The rods define surface sections of the furniture, which can be filled with appropriately designed side walls. Although these side walls are designed to be interchangeable, since inserts such as tilt doors, swing doors, trays, pull-outs, etc., are fastened to the side walls from the inside, the replacement of a side wall is complicated since the inserts must first be dismantled.

Presentation of the invention

The object of the invention is therefore to provide a the technical field mentioned above belonging furniture, which is a simple and quick adaptation of the furniture to changing needs, especially with regard to the color and / or material design of the outer shell but also with regard to the equipment of the furniture functional applications such as tilt doors, swing doors, trays, drawers, etc. allows.

The solution of the problem is defined by the features of claim 1. According to the invention, it is a piece of furniture with at least one frame-shaped, structuring framework. This framework virtually defines an area of a wall of the piece of furniture and is designed in such a way that a surface filling element for filling this wall area can be fastened to the frame. The inventive furniture is characterized in that the framework is now designed such that at least two Flächenfüllemente be fastened thereto, which form a double-walled portion of this region of the wall of the furniture.

As a result of this embodiment of the piece of furniture and in particular of the structure-providing frameworks, it is possible, for example, to form the outer shell completely or at least partially double-walled. Ie. For example, a first Flächenfüllelement forms the outwardly directed outer surface of the furniture and a second Flächenfüllelement forms the inwardly facing surface of the furniture. Each frame-shaped, structural framework can be provided with an arbitrary, outer Flächenfüllelement and with any inner Flächenfüllelement, wherein the outer and inner Flächenfüllelement can be replaced independently. The outer Flächenfüllelemente are in this case particularly crucial for the appearance of the furniture, whereas the inwardly directed Flächenfüllelemente can be provided with the necessary and desired uses. The invention thus makes it possible, for example, to change the external appearance of the furniture by simply replacing the respective outer Flächenfüllelemente, without having to change the structure or the possible use something. Furthermore, the invention also makes it possible to virtually change the interior of the piece of furniture without having to change anything on the external appearance.

According to the invention, however, not only the outer shell or areas thereof may be double-walled, it is of course also possible to equip interior walls, shelves or other interior and exterior surfaces of the furniture with inventive frame-shaped scaffolding and to provide with two Flächenfüllelementen. Again, this makes it possible to replace the interior of the piece of furniture in an area independent of the adjacent areas.

This opens up a variety of design and usage options, not only the use of a piece of furniture for a variety of applications, but also a Extension of the life of the furniture allowed. As it can be easily and quickly adapted to the latest color and / or material trends, for example, furniture can stay in use longer.

The frame-shaped, structuring framework is, for example, elongate, in particular rod-shaped construction elements, which are connected to each other in principle to any, usually two-dimensional, geometric figures. The term frame-shaped in this context means that these figures form a kind of frame in which the Flächenfüllelemente be used. However, this framework does not necessarily have to be completely closed. For example, it could also include struts to make the frame more resilient. The furniture can be constructed from one or a plurality of such frame-shaped frameworks. Ie. These scaffolds are attached to each other and thus form the three-dimensional structure of the furniture (which is why the term is used to give structure to the frameworks). Typically, for such a frame-shaped framework four rod-shaped construction elements are connected by means of four connecting elements to a rectangular, in particular square frame, a plurality of such frames to cuboidal bodies and a plurality of such bodies to the desired structure.

Further, the term wall in the context of the present invention is to be understood as meaning both a section of the outer casing (side wall, floor, lid, etc.) and any wall section in the interior of the furniture (side wall, floor, lid, partition, Intermediate tray, etc.). In addition, the term double-walled is not to be construed so narrowly that it includes only double walls, which are arranged at a certain distance and more or less parallel to each other. It should also include double walls, for example, which lie close to each other and leave no space between them.

The furniture according to the invention may be virtually any piece of furniture. However, this system is very well suited for the provision of shelves, showcases, sideboards and similar furniture.

The furniture may be a piece of furniture with a solid, d. H. act unchangeable structure. This may have one or more frame-shaped scaffolding, which are firmly connected to each other and can not be extended or disassembled. Preferably, however, the furniture is modular, so that not only the external appearance and the interior, but also the structure of the furniture is generally adaptable.

In an advantageous embodiment of the invention, the frame-shaped frame is designed such that the Flächenfüllelemente can be selectively fixed therein and removed again. Next, the furniture is advantageously designed such that the insertion or removal of the Flächenfüllelemente can be done without having to change the structure of the furniture. Ie. the insertion or removal of the Flächenfüllelemente can be done while maintaining the structure of the furniture. To change, for example, the color of the furniture, only the outer surface filling elements of those frame-shaped frameworks must be replaced, which virtually span the outer shell of the furniture. This can consequently with very little effort, d. H. done easily and quickly.

The frameworks or the Flächenfüllelemente are in this case advantageously designed such that the insertion and removal of the Flächenfüllelemente can be done by hand. Instead of using, for example, screw, adhesive, rivet or similar compounds that are not or only with great effort again be solved, the scaffolding or Flächenfüllelemente with easily and quickly by hand again releasable connection devices such as clamping, locking or provided magnetic holding devices, which allow the creation or release of a connection with a few simple steps. By hand in this context means by no means that, for example, to release a Flächenfüllelementes no tools may be used. It simply means that, for example, no screw connections have to be made or loosened for insertion or removal, or that no machines are used for this purpose. By "hand", for example, the use of tools (such as suction cups or similar vacuum holders or hook-shaped structures) understood to the mounted, usually even to take trained Flächenfüllelemente and pull out of the frame-shaped framework.

The insertion (and accordingly the removal) of the Flächenfüllelemente in or out of the framework can be done in principle in various ways. For example, the surface filling elements could be pushed laterally into the frame. Ie. in a direction parallel to the plane defined by the framework. However, the frameworks and the area filling elements are preferably designed such that a first area filling element consists of a first direction substantially perpendicular to a plane defined by the framework and a second area filling element of a second direction substantially opposite to the first direction, into the framework can be used. In this way, it is ensured that the furniture structure for attaching or detaching the Flächenfüllelemente not changed, d. H. the scaffolding does not have to be taken apart.

So that the Flächenfüllelemente a single frame-shaped frame can be actually used independently or taken out, the scaffolding or Flächenfüllelemente are formed in a preferred embodiment of the invention such that a second Flächenfüllelement in the frame is attachable and removable, while a first Surface filling element is mounted in this framework.

The frame-shaped framework can be made in various ways. It may, for example, consist of several individual parts or be constructed in one piece. In a preferred embodiment of the invention, the frame-shaped, structural framework comprises a rectangular, in particular square frame with a plurality of rod-shaped edge elements and a plurality of connecting elements in the corners of the rectangular frame for connecting the edge elements. Several such frames can then be connected together so that they are either perpendicular or parallel to each other. Two adjacent frames are typically assembled in such a way that they have a common edge element and two common connecting elements. Ie. to an existing frame, another frame is typically set such that an edge element of the existing Frame is supplemented with one, two or three additional edge elements and the corresponding required number of fasteners to another frame.

In this way, the frames, according to the rectangular shape of the framework, can be made into any cubic structures. In the case of rectangular or square frameworks, the basic structural unit for the furniture is consequently a cuboid or cube, from which practically any type of furniture can be built.

Also for securing the Flächenfüllelemente in a frame-shaped framework, there are different possibilities. For example, the surface filling elements could be firmly connected to the frame by gluing, soldering, welding, screws, etc. However, in this case it would no longer be possible to exchange the area filling elements quickly and easily. An edge element therefore preferably comprises a fastening device directed into the interior of the rectangular frame, to which the surface filling elements can be fastened. Accordingly, the surface element has a suitable fastening element which, together with the fastening device, permits a connection of surface filling element and frame-shaped framework which can be released again in a simple manner. Such types of connection include, for example, magnetic or clamping or latching connections. In the case of compounds based on magnetic forces, the fastening device would comprise, for example, an intermediate piece, which can be fastened to the frame, made of a magnetic or magnetizable material and a magnet which can be fastened to the surface filling element. However, since, for example, magnetic connections are unsuitable for certain applications (for example furniture on or in which metallic jewelery products are stored or presented), the connections between the surface filling element and the frame are preferably designed as a clamping or latching connection, which is for example applied by manual pulling A surface filling element can be easily and quickly released from the frame.

The fastening device and the fastening element are preferably designed such that it is not visible from the outside, as the Flächenfüllelement is fixed in the frame. The surface filling element fastened in the framework virtually hides the attachment of the surface filling element in the framework. The term "from the outside" refers to this Associates the line of sight on the framework of that side, which is filled with the area filling element. If two Flächenfüllelemente secured in such a framework - one from each side - the fasteners are no longer visible from any side, since the fasteners and the corresponding fasteners are completely inside the closed by the Flächenfüllelemente scaffolding. This invisibility of attachment of the Flächenfüllelemente on or in the framework is in particular for aesthetic reasons an advantage. The furniture can for example be designed so that the desired by the designer of the furniture optics is not affected by visible fasteners.

By appropriate choice of the thickness of the Flächenfüllelemente it is possible in this way to make a closed surface of the furniture. In this case, the surfaces of the framework may be visible and form part of the furniture surface or the Flächenfüllelemente may also be designed such that two adjacent Flächenfüllelemente the front side abut each other and so cover the underlying framework at least partially.

An advantageous connection, which is easy to produce, comprises, for example, a pin fastened to an edge element and a fastening element fastened to the surface filling element. The latter includes a latching device with, for example, two staggered, provided with locking lugs projections. During assembly, the locking device is now pressed onto the pin so that it is positioned between the two projections and held by the locking lugs. The pin is typically inward, d. H. directed towards the interior of the frame and lies parallel to the plane defined by the frame or the surface filling element used. The projections are made, for example, of a flexible material, i. H. slightly springy. Thus, the pin is pressed virtually behind the locking lugs of the projections. To solve such a connection then simply a certain, applied by hand tensile force on a Flächenfüllelement must be exercised so that the projections yield and the pin can be brought back in front of the locking lugs.

In order to obtain a stable connection despite the ease of re-releasability of the connections, a frame-shaped framework typically comprises a plurality of such pins and a Flächenfüllelement can be provided in accordance with a plurality of such fasteners. The pins and the corresponding latching devices in this case preferably have different directions within the said plane, for example they are perpendicular to one another. This allows the Flächenfüllelement be precisely fixed in the desired position in the frame.

According to the invention, a Flächenfüllelement for a piece of furniture of the type described thus comprises a base member made of a solid material such as wood, plastic, metal or glass. Furthermore, it comprises at least one fastening element for attachment to the frame-shaped, structuring framework of the furniture. The surface filling element according to the invention is now characterized in that the fastening element is designed as a separate component and can be connected to the base element. As already mentioned above, the fastening element can be a magnet which is fastened to the base element and interacts with a magnetic or magnetizable material (for example an iron-bonded plastic) attached to the framework. Of course, but also the fastening device may be a magnet and the fastening element made of a magnetic / magnetizable material. It would also be possible to form both fastener and fastening device as mutually attracting magnets.

As also already mentioned, the fastening element can also be designed as a latching / clamping device.

Basically, the base element can have any shape, for example, it can have a curvature, so that a piece of furniture with a curved surface can be produced. In an advantageous embodiment, the base element is designed as a flat plate and comprises in the region of an edge of the plate at least one recess into which the fastening element can be inserted. The recess may, for example, continuously, ie from one side (main surface) of the plate to the other side reach, or not continuously, ie be formed as a kind of blind hole. The geometric shape of the plate typically corresponds to the shape of the frame-shaped frameworks of the furniture structure, so that these frames can be filled more or less completely with the surface filling elements. Conceivable, however, would also be surface filling elements, those of the frame only partially fill the enclosed area. Of course, surface filling elements are possible, which do not have a continuous closed base element, but for example, holes and openings or any structured surfaces.

In order to connect the fastening element with the base element, this has a corresponding shape of the recess in the base element, in which it is to be inserted or inserted. This allows a simple, strong and u. U. again releasable connection between the base member and a fastener can be achieved.

In a particularly preferred embodiment of the invention, the fastening element is connectable by means of a positive connection with the plate. Ie. the recess is profiled, for example, and provided on a front side of the plate. The fastener in this case has one of the profiled recess corresponding shape and is easy and without effort end face, d. H. inserted in a recess lying parallel to the main surface of the plate in the recess. Since the plate is claimed both during insertion as well as during removal and in the mounted state mainly perpendicular to this direction, can be dispensed with an additional attachment of the fasteners in the recess (for example, by gluing). Accordingly, the fasteners can also be easily removed again, which allows, for example, a simple and quick disposal, in which the plates and fasteners can be disposed of separately or recycle, which not only from an environmental point of view offers great advantages.

Although possible other connections between plate and fastener such as glued, welded, soldered or other compounds of a similar nature would be possible. However, these are difficult to solve again and a separate recycling or disposal is not possible. It would be conceivable, in principle, also an integrally formed Flächenfüllelement, in which the or the fasteners are already formed, for example, produced by an injection molding process.

The base member may also be made of any materials such as plastics, metals, ceramics, glass or other materials or even corresponding composite materials.

Preferably, however, the base elements are made of wood or a material made of wood such as solid wood panels, plywood (plywood), flat-pressed panels (chipboard), MDF boards, other wood fiber boards or any other wood-based materials. This allows a simple, even industrial production and processing with widely used machines. The surfaces can be designed in many different ways. They can be structured as desired, dyed, painted or even with veneers or other surfaces such. B. resin coatings are provided. As a result, the appearance of the Flächenfüllelemente and thus the entire piece of furniture can be virtually any change and adapt.

The fastener, however, is preferably made of plastic. Plastic is a cheap and widely available material. It not only allows the desired flexibility and thus spring action of the projections, but also allows a simple and inexpensive, especially industrial production in large numbers, for example by injection molding.

The Flächenfüllelemente can be used and used as they are, for example, with a smooth, continuous surface. Preferably, however, some surface fill elements have recesses that can be used to secure fittings for the various inserts. Such recesses may for example be formed as grooves or other recesses in one or both main surfaces of the base elements. Accordingly, no fittings are attached to the framework of the piece of furniture, ie, its structure in the rule. The depth of the recesses (these can also be continuous from one main surface of the base element to the other) is variable as well as, for example, their size (ie areal extent). The recesses are designed in particular as holes, which can be easily and quickly produced. These recesses may be both specific to a particular type of fittings aligned, but they can also be used as a standardized grid of similar recesses, such as regular Arrangement of holes of a certain diameter, be attached, wherein the different types of fittings also have corresponding hole pattern, with which they can be screwed to a Flächenfüllelement example. Preferably, these fittings can be attached both to a not used in a frame as well as on a already used in a frame Flächenfüllelement. Ie. The interior of the furniture can either be used at the very end, after the structure of the furniture and the outer skin are completely assembled, or the furniture can be assembled from prefabricated individual elements including fittings. As a result, it is of course also possible to renew an existing interior completely or partially and without disassembly of the furniture.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Ways to carry out the invention

FIG. 1 shows a detail of a piece of furniture 1 according to the invention. Shown is a corner of the piece of furniture 1, in which three edge elements 2.1, 2.2, 2.3 converge and are held by a connecting element designed as a cube 4. The edge elements 2.1, 2.2, 2.3 have a square cross-section, wherein the edge length of the cube 4 with the edge length of the cross-sectional square of the edge elements 2.1, 2.2, 2.3 matches. Accordingly, the three edge elements 2.1, 2.2, 2.3 are each connected to one end face on respectively adjacent side faces of the cube 4 such that each of them is perpendicular to the other two. The edge elements may also have other cross sections, such as, e.g. a circular, elliptical, polygonal, etc. cross section.

The edge elements 2.1 and 2.2 (together with further, not shown edge elements) define a rectangular frame 10 in this case. The edge element 2.1 has a hole in the side surface 8.1, which is directed into the interior of the frame 10 at a distance 5 from the cube 4 6 on. In this hole 6, a shaft screw 7 is screwed.

The frame 10 forms an arbitrary inner or outer surface, in the present case an outer surface of the furniture 1. By inserting an outer Flächenfüllelements, hereinafter referred to as filling 11.1, in the frame 10, the furniture 1 is provided with an outer shell. The filling 11.1 comprises a wooden plate 12.1, which at its lower edge, more precisely in its downwardly directed end face 13.1, has a recess 14 (all directions and position information relate, unless otherwise stated, to the representation chosen in the respective figures ). This recess 14 is also arranged at a distance 5 from the right-facing end face 13.2. In this recess 14, a fastener 15 is inserted from below. The fastening element 15 consists for example of a flexible plastic and comprises a base 16, the shape of which is adapted to the shape of the recess 14, and two projections 17.1 and 17.2 projecting at right angles from the base 16. The two projections 17.1, 17.2 are arranged offset one above the other and have at their projecting end in each case a latching nose 18.1, 18.2. The projection 17.1 is arranged slightly further to the left, with its detent 18.1 pointing to the right and the projection 17.2 is arranged slightly further to the right and below the projection 17.1, wherein the detent 18.2 points to the left. Looking from below or above (along the surface of the wooden plate 12.1) on the fastener 15 on it, between the two projections 17.1, 17.2 an opening can be seen on two sides of the two projections 17.1 and 17.2 and on the other two sides the base 16 and the two locking lugs 18.1, 18.2 is limited. This opening is dimensioned so that it approximately corresponds to the cross section of the shaft screw 7. The two projections 17.1, 17.2 thus form with their locking lugs 18.1, 18.2 a clamping device for the attachment of the filling 11.1 on the frame 10th

The filling 11.1 is now fastened in the frame 10 by being inserted in the frame 10 in the direction of the arrow 19.1. Since the distance 5 of the shaft screw 7 from the cube 4 coincides with the distance 5 of the fastening element 15 to the end face 13.2, the shaft screw 7 is pressed upon insertion of the filling 11.1 in the frame 10 between the two projections 17.1, 17.2. Here, the two ends of the projections 17.1, 17.2 with the detents 18.1, 18.2 initially pushed apart from the shaft screw 7. If the filling 11.1 moves further in the direction of arrow 19.1, slide the projections 17.1, 17.2 with their locking lugs 18.1, 18.2 back to their original position, so that the shaft screw 7 finally in the through the projections 17.1, 17.2 and the locking lugs 18.1, 18.2 opening formed. The dimensions are in this case dimensioned such that the shaft screw 7 is fixed in fully inserted filling 11.1 in this opening. So that the filling does not wobble 11.1 in the frame 10, at least one such fastening device is provided in each corner of the filling 11.1 and the frame 10.

Similarly, a second inner filling 11.2 is secured in the frame 10. In the example shown in FIG. 1, this forms an inner wall of the furniture 1 and is inserted into the frame 10 in the direction of the arrow 19. 2, which is essentially opposite to the direction of the arrow 19. Also, the filling 11.2 comprises a wooden plate 12.2 and a not visible in the illustration according to FIG. 1 fastener in its lower end face. The filling 11.2 has, for example, a multiplicity of bores 20 which serve for fastening fittings of all kinds (for example for the realization of drawer or other pull-outs, tilting elements, pivoting elements, intermediate shelves, etc.).

The thickness of the fillings 11.1, 11.2 is preferably dimensioned such that their respective outer surfaces are flush with the corresponding side surfaces 8.2, 8.3 and 8.5, 8.6, so that the outer surfaces of the fillings 11.1, 11.2 with these side surfaces 8.2, 8.3, 8.5, 8.6 each form a plane.

If the filling 11.1 fixed in the frame 10, the attachment, d. H. the shaft screw 7 on the edge element 2.1 and the fastener 15 on the filling 1 1.1 from the outside, d. H. if a viewer looks at the furniture in the direction of arrow 19.1, invisible. Likewise, the attachment of the filling 11.2 from the outside (viewed in the direction of arrow 19.2) invisible when it is mounted in the frame 10.

Instead of the shaft screw 7 could be used to attach the fillings 11.1, 11.2 on the frame 10 and a differently designed retaining pin, for example, a pressed into a side surface of the edge element 2.1 mandrel. It would also be possible to form the fastening device as a plate or plate, which is inserted into a corresponding groove in the edge element 2.1. The shape of the fasteners 15 would have to be adjusted accordingly.

The fillings 11.1, 11.2 can of course be attached to the edge element 2.2 in a manner similar to the edge element 2.1, if the side surface 8.4 directed inside the frame 10 likewise provides the edge element 2.2 with a shaft screw and the fillings 11.1, 11.2 with corresponding recesses and fastening elements becomes. This variant is not shown for clarity.

In the same way, one or two further fillings can also be inserted into the frame formed by two other edge elements 2.1 and 2.3 or 2.2 and 2.3.

By further edge elements are also grown on the other side surfaces of the cube, the furniture 1 can also expand virtually any, with each resulting frame two fillings can be used. The attachment of edge elements to a cube is described below in connection with FIG.

FIG. 2 shows a further possibility of inserting a filling 11.3 into a frame comprising the edge element 2.1. In or on the side surface 8.1 of the edge element 2.1 in this case not a screw, but an intermediate piece 21 is fixed (for example glued or the edge element 2.1 has a profiling and the intermediate piece 21 has a corresponding mating counter-profile, with which it is used in the profiling can be). This intermediate piece 21 is made of a magnetizable material (for example, an iron-bonded, ie, an iron-containing plastic) and T-shaped, with the crossbar of the Ts on the side surface 8.1. is attached. The filling 11.3 in turn has a recess 14, which is circular in this case. In the recess 14, a circular disk-shaped magnet 22 is inserted. To insert the filling 11.3 in the frame with the edge element 2.1 this is again performed in the direction of the arrow 19.1 to the frame. Are the filling 11.3 with the magnet 22 and the intermediate piece 21 close enough to each other, they are attracted to each other by the magnetic force and the filling 11.3 is completely pulled to the intermediate piece 21 and held on it. Again, several such fasteners are again provided.

FIG. 3 shows by way of example a possible cross section of the edge element 2.1. This is, as already mentioned, square and has interconnected sides 23.1, 23.2, 23.3, 23.4, wherein the surface of the side 23.1 forms the side surface 8.1 of the edge element 2.1, in which the hole 6 is located. In the middle, the cross section has a circular ring 24, which is connected by diagonal struts 25 in the corners of the cross section. This creates an X-shaped cross with a hole 33 in the middle, which gives the edge element 2.1 with relatively low material consumption high stability.

FIG. 4 shows that section of the filling 11.1 where the fastening element 15 is inserted in the recess 14 of the wooden plate 12.1, in a view of the end face 13.1. The base 16 has a substantially rectangular shape with a circumferential groove 29. The counterpart to the groove 29 forms a circumferential projection 30 of the recess 14. Groove 29 and projection 30 are matched to one another such that the fastening element 15 fits exactly into the recess 14. The projections 17.1, 17.2 are at right angles away from the base 16 and the latching lugs 18.1, 18.2, which are integrally formed at the end of the two projections 17.1, 17.2, face each other. Between the two projections 17.1, 17.2, the two locking lugs 18.1, 18.2 and the base 16 an opening 31 is formed in this way, in which the shaft screw 7 (indicated by a dashed circle) is received, the shaft screw 7 in the direction of the arrow 32 is pressed into the opening 31.

FIG. 5 shows in a schematic sectional view how an edge element 2.1 is fastened to the cube 4. The edge element 2.1 has in its side surface 8.1 the hole 6 for the shaft screw 7, which has an external thread 26 for attachment in the hole 6. The cube 4 has an outer cube 4.1 and an inner cube 4.2 with rectangular holes 37. In one of these holes 37, a bolt 34 is screwed with two equal ends 34.1, 34.2 and a thinner middle part 34.3, for which purpose a threaded extension 35 is provided at the end 34.2. This bolt 34 is now inserted into the hole 33 in the middle of the edge element 2.1. In the side surface 8.1 is located next to the hole 6 for the shaft screw 7, a further hole 27, which is at fully inserted bolt 34 in the region of thin middle part 34.3 is located and in which a grub screw 28 can be screwed. The grub screw 28 is screwed in so deep that its lower end in the region of the thin middle part 34.3 protrudes into the hole 33 and in this way prevents the pin 34 from falling out of the edge element 2.1 and fixes the pin 34 in the hole 33.

By further bolts are screwed into the holes 37 of the inner cube 4.2, a total of six edge elements (namely, an edge element on each side surface of the cube 4) can be attached to a cube 4.

To attach the various screws in the various holes they are provided with corresponding internal threads.

Figure 6 shows a plan view of the side surface 8.1 of the edge element 2.1 with the fillings 11.1 and 11.2 attached thereto. Both fillings 11.1, 11.2 comprise a fastening element 15.1, 15.2, each with two projections 17.1, 17.2 or 17.3, 17.4 and the corresponding latching lugs 18.1, 18.2 and 18.3, 18.4, which in turn form the openings 31.1 and 31.2. In the illustrated, fully assembled state, the shaft screw 7 is encompassed both by the projections 17.1, 17.2 and the projections 17.3, 17.4, so that the two openings 31.1, 31.2 virtually coincide. Both fillings 11.1, 11.2 are thus attached to the same shaft screw. This type of attachment is possible because the two projections 17.1, 17.2 or 17.3, 17.4 of a fastener 15.1 and 15.2, as shown in Fig. 1, are arranged offset one above the other. As shown in Fig. 6, the projection is 17.1 of the fastener 15.1 before (as shown) the projection 17.3 of the fastener 15.2 and conceals this part. Conversely, however, the projection is 17.2 of the fastener 15.1 behind the projection 17.4 of the fastener 15.2 and is partially covered by this.

FIG. 7 shows a schematic perspective view of a complete frame 10 with two fillings 11.1, 11.2 which can be fastened thereto. The frame 10 comprises four edge elements 2.1, 2.2, 2.4, 2.5 and four cubes 4, via which the four edge elements 2.1, 2.2, 2.4, 2.5 are connected to a square. In the respective inner (inside the Frame 10 pointing) side surfaces of the edge elements 2.1, 2.2, 2.4, 2.5 are each two shaft screws 7 (one in the region of each end of an edge element) used. The filling 11.1 comprises the square wooden plate 12.1, which on the side facing the frame 10 has eight recesses 14 (two each in an end face of the wooden plate 12.1 in the region of their corners). In the two upper and the two lower recesses 14, a fastening device 15 is used in each case. In the four other recesses 14 no fasteners 15 are used in the example shown, and this would also be possible without problems to increase, for example, the stability or strength of the connection between the frame 10 and the filling 11.1.

The filling 11.2 is also provided with recesses 14, some or all of which are provided with fastening devices 15. Both fillings 11.1, 11.2 can now be secured in the frame 10 by the fillings 11.1, 11.2 are pressed with the respective fastening devices 15 on the shaft screws 7.

The fillings used in this way can be easily removed again by pulling the corresponding filling away from the frame 10. This can for example be done with a simple suction cup, which is simply attached to the surface of the filling and removed after the removal of the filling. This can be done easily and quickly by hand.

The filling shown in Figure 8 11.2 further has a plurality of grid-shaped mounted holes 20, which serve for screwing fittings (not shown) in a known manner.

Finally, FIG. 8 schematically shows a piece of furniture 40, but without any fillings. Ie. only the structure of the furniture 40 is shown, which is constructed from a plurality of cube-shaped or cuboidal basic elements 41, which in turn are each constructed from a plurality of frames 10. In each of the side surfaces of these basic elements 41 according to the invention two fillings can be used in each case, wherein both independently and without having to change the structure of the furniture 40 something to be used and removed again.

Of course, it is also possible to use a piece of furniture according to the invention with further elements and features such as e.g. Feet, sockets, various brackets, etc. to provide.

The illustrated examples can be varied in many ways. Thus, the edge elements may also have other cross sections. For example, the side surfaces of the edge elements can also be designed as interchangeable cover profiles, so that their appearance can be changed easily and quickly. Accordingly, for example, the sides 23.1, 23.2, 23.3, 23.4 of the cross-section shown in Fig. 3 would not belong to the edge element, but be designed as a separate, can be placed on the X-shaped cross elements. The same applies of course to the side surfaces of the cubes.

The preferred material for the edge profiles and the cubes is aluminum, which is characterized by high strength with low weight and also offers advantages for aesthetic reasons. Separate top surfaces for the edge elements or the cubes are preferably made of plastic or also of aluminum.

In summary, it should be noted that the invention allows the production of an extremely flexible furniture or furniture system that can be adapted to constantly changing needs. In no time, the furniture fronts and surfaces of the edge profiles can be replaced without disassembling the furniture. This makes it possible, for example, within a very short time to create a completely new appearance of the furniture or to completely redesign the interior, for example, from drawer inserts to flap modules.
