Description

in DK 2002 00091 U3

The present invention relates to a component-based skeleton furniture system as described in the preamble of claim 1.

Various component-based furniture systems are known, which are built with a three-dimensional skeleton. Generally, the skeleton is made up of tubular components and corner components to which the tubular components are attached, whereby the tubular components are interconnected.

The attachment of the tubular components to the home components is effected, for example, by the tubular components being partially pushed into the home components, or by the home components being partially pushed into the tubular components. A system utilizing the latter principle is described in US Patent US 5,678,706.

In these prior art systems, home angles are straight, and countertops or drawers placed in the skeleton are rectangular.

These prior art systems can be assembled and disassembled without the use of tools. In order to obtain a high stability so that the skeleton does not fall apart even during loading and lifting, the home components must be designed with such a small tolerance that the pipe components must be pressed together with the home components during assembly. This has the disadvantage that it can be difficult to disassemble the components when the furniture system has to be dismantled in order to possibly change its shape or when the system has to be moved, transported and the like. Furthermore, it is common for these known systems, after being mounted and dismantled several times, to lose their original stability.

The unit cell of the known furniture systems are rectangular boxes, the height of which is usually variable in the individual systems, but where the width and depth of these rectangular box-shaped unit cells are constant. Thus, the finished furniture system is composed of these unit cells in succession.

2 2GB 2002 00091 U3

It is the object of the present invention to provide a component-based furniture system with the skeleton where the components are easy to manufacture, where the number of different components is small, where assembly and disassembly of the components can be done easily and without the use of tools, and where the mounted system is stable during loading and lifting of the furniture system, even after the components have been mounted and dismounted several times.

This object is achieved with a component-based furniture system with the skeleton of the type mentioned initially, which is characterized as described in the characterizing part of claim 1.

In the component-based furniture system with the skeleton of the invention, the skeleton is formed mainly of column components and interconnected carriers. The fastener comprises an outer thread extending the first end of the column component, preferably the upper end, and an internal thread at the second, preferably lower, end of the column component. Thus, several column components can be screwed together in succession. The outer thread extending the first end of the column component may be provided by a pin disposed at the first end. Preferably, however, the external thread is provided by providing the first end of the column component with an internal thread and then by screwing a threaded piece into this inner thread, which thread length is longer than this inner thread.

The column components are preferably cylindrical, but may also be made with a second cross-section, for example an oval, triangular or square cross-section, and also with a non-constant cross-section along the column component, for example, cone-shaped, pyramid-shaped or as hyperboloid. Furthermore, like the other components, the pillar components may be variously ornamented for the purpose of functionalism and / or aesthetics. In the latter case, however, the other components must be adapted to this. In the following, it is assumed that the column components are cylindrical.

3 DK 2002 00091 U3

The drawers are provided with holes having a size such that a first column component can be placed with the thread through the hole. By screwing a second column component thereafter in extension of this first column component, the draws between the two column components are retained. Similarly, by attaching pillar components and supports to one another, a skeleton can be made.

Both pillar components and carriers are very simple to manufacture, and in principle these two types of components are sufficient to build a skeleton whose shape is very variable. The mounting by mutual screwing of the column components in the skeleton is done without tools and is very stable under load and lifting. Stability is maintained at length also by repeated assembly and disassembly.

In another embodiment of the invention, the column components have the same length. This is appropriate as it simplifies the manufacturing process and minimizes the number of different components. If a longer column is desired than the column component, several column components can be screwed together in succession without intermediate kites.

The drawers may have different lengths, however, the lengths of these drawers will be adapted to the other components, for example shelves, partitions or drawers included in the furniture system.

A simplification of the system is achieved in a further embodiment of the invention by producing the drawers in lengths which are essentially a multiple of a unit length. Along with the unit length of the column components, the invention differs from the prior art in that the invention has a fixed length of column component, but there is a variable length of dragons; In the prior art, a variable length of column component is used, but a fixed length of the carriers used to define the width of the unit cell and a fixed length of the carriers used to define the depth of the unit cell. The advantage of the invention is that simple and different components are obtained, but with a greater variety of shapes for the finished furniture. For example, the furniture system with a carrier that is longer than the unit length and supported by columns of the 4 ends 2002 00091 U3 the two ends of the carrier may span an object longer or wider than the unit length; this object may be, for example, another piece of furniture, plant or the like. This is not possible with the known system described in the US patent mentioned above.

In case the length of a kite is roughly a multiple of a unit length, the unit cell will typically be an equilateral triangle. In order to be able to form structures with both triangular and square ground area, it is an advantage of a unit cell having a ground area that has the shape of a right-angled, straight-legged triangle. In this case, two sets of kites are required, one set corresponding to the two catheters of the right-angled, straight-legged triangle, where one kite is substantially a length that is a multiple of a unit length, and another set corresponding to the hypotenuse in the triangle, where a kite has a length that is roughly a multiple of a unit length multiplied by V2 (the square root of 2).

The drawers have a certain thickness, and to ensure that parallel columns of the skeleton have the same height, although in each column not the same number of drawers are mounted, in a further development of the invention a spacer / spacer with the same height as the thickness of drageme. These spacers are placed around the thread between the column components when no kites are placed with the hole around the thread between the column components. The skeletons of the skeleton will thus always be at right angles to the columns, which is practical, ensures stability and is aesthetically pleasing.

At the end of the upper part of a column, in a further embodiment of the invention, there is provided a fastening means which includes a nut which is screwed onto the top thread of the column. The carrier is thus secured to the column by being clamped between the top of the column and the nut. The nut may be aesthetically designed, for example as an ornamented, closed disc with thread in the lower portion of the disc, and may function as a support for a countertop mounted on top of the skeleton. In a preferred embodiment, the worktop is provided with holes suitable for the nut. In this case, the worktop will rest on the edge of the carrier or spacer under the nut and with the nut in the hole, ensuring that the worktop 5 cannot slide sideways on the skeleton. The holes in the worktop have the advantage of being able to build on the skeleton in height above the worktop. Furthermore, the nut may be provided with an upper, disc-like portion having a larger diameter than the tabletop hole. Such a nut, when placed in the hole for the worktop and screwed into the column, will not only ensure that the worktop cannot slide sideways on the skeleton, but also prevent the worktop from being unintentionally lifted free of the skeleton. The nut can also be an aesthetic and safety finish on the upper part of the column, although no kite is attached.

The principle of attaching the drawers to the columns allows varying angles between the drawers. The angles need not be straight as in the prior art, which is a further advantage, as the skeleton of the furniture system can thereby be adapted to other forms of shelves than rectangular.

In a further embodiment of the invention, the furniture system comprises triangular plate components. These are intended as shelves in the furniture system. Choosing triangles rather than rectangles results in a much greater variety of possible shapes for the final piece of furniture. It also has the effect for the user that the user has the opportunity to reshape his furniture and adapt the furniture by remodeling in a home or by moving to a new home. Furthermore, it allows the user, through creative efforts, to renew their contents without having to buy new furniture.

The triangular plate components can be made of different materials, for example metal, glass or wood, including different types of wood. They can also be made in different colors, which allows the user to further customize the furniture to his other furniture. The triangles can have different shapes, however, triangles with corner angles of 60 ° - 60 ° - 60 ° (equilateral triangle) or 90 ° - 45 ° - 45 ° (equilateral, right-angled triangle) would be preferred. Advantageously, the shape of the plate component corresponds to the base area of the unit cell.

The furniture system may contain a number of useful elements, such as partitions, drawers and / or doors. These elements may be placed in the system upon initial mounting or may be placed afterwards. The component design also permits continuous production and offering of new variants of components and new products in connection with the furniture system to the customer. Drawers and shelves may be triangular, but may also have other shapes, for example rectangular, such as square.

Furthermore, the furniture system, if manufactured in wood, can be manufactured in different price categories when choosing expensive or inexpensive types of wood. In addition to wood, it is also possible to use other materials, such as metal, glass and / or plastic, for the individual components. By mixing different materials in the furniture system, the manufacturer can easily create furniture systems with very different appearance, and the user can, with relatively little effort and at relatively low cost, even create a new furniture by acquiring individual components in, for example, another material or in a different color.

By appealing to the user to redesign the furniture or to recreate the furniture, for example, with components of a new color or material, the system is expected to have a longer life than other known component-based furniture systems, where the user becomes tired of the system faster and replaces this with other furniture. As the furniture system according to the invention is more timeless and adaptable as described, the invention thereby counteracts the phenomenon known to the industrial world that older items are discarded and replaced by newer, more modern items long before the older items are worn or lose function. -naliteten. The invention thus also to a certain extent focuses on being environmentally sound.

In the following, the invention will be described with triangular unit cells, but the basic area of the unit cells may also have other shapes, such as rectangular or space-shaped.

The invention will then be described in more detail with reference to the accompanying drawing, in which: FIG. 1 shows skeletal components according to the invention; FIG. 2 is an example of a skeleton in side view; FIG. 3 shows the assembling technique of a skeleton; FIG. 4 illustrates the skeletal assembly process; FIG. 5 shows the assembly level by level of a simple example of a table top furniture system according to the invention; FIG. 6 outlines some examples of forms of furniture systems according to the invention; 7 shows examples of furniture systems according to the invention with triangular shelves; 8 shows a corner of a triangular shelf / plate with a circular arcuate recess; FIG. 9 shows a corner of the skeleton with counter top and the nut which acts as a support button for the counter top; FIG. Fig. 10 shows an example of an embodiment of a foot for a pillar of the furniture system; Figure 11 shows an example of a furniture system where the base area of the unit cell is a straight-legged, right-angled triangle; Fig. 12 shows a removable space placed in a skeleton; 13 shows a partition mounted between two column components FIG. 14 is a cross-sectional view of a partition.

Figure 1 shows components for use in building the skeleton of the furniture system. Three of the components, one carrier 1 in unit length, another carrier 2 of length approximately equal to two unit lengths, and a spacer 3, are shown from above, and the other three components shown, a column component 4, a nut 5 and an assembly screw 50 are shown from the side. The unit length is defined as the distance between the two holes 6 in the shortest drag. A carrier 1 with one unit length can connect two columns and a carrier 2 with two unit lengths can connect two or three columns. The column component 4 has a central hole 17 with an internal thread 15 at the bottom of the column component and an external thread 7 in extension of the upper part 8 of the column component 4, which thread 7 has the same diameter and pitch as the internal thread at the bottom of the column component. 4 so that the two threads 7, 15 can cooperate. Both threads are included in the fastener as disclosed in the claims. Assembly screw 50 can act as the lower end of a column. This component can be designed in different ways and serve as a base for the column.

Figure 2 is an example of a skeleton with three levels 11, 12, 13 in side view. Drums 1, 2 and the column components 4 can be connected in levels whose number determines the height of the skeleton. In the lower level 13, two column components 4 and one carrier 2 are used which have a length corresponding to two unit lengths. Furthermore, the carrier 2 with its middle hole is attached to the column component with a connecting screw 50. This configuration is advantageous when the carrier 2 spans an object, for example a plant wider than the unit distance, or if it is chosen for aesthetic or practical reasons. to place an object under the middle hole of the carrier. In second level 12, a carrier 1 having a length corresponding to one unit length, two columns 4 and a nut 5 is used as the end of the right column component, and in third level 11 one column component 4, one spacer 3 is used. and a nut 5 as the end of the column.

Figure 3 shows the assembly technique for a skeleton. The column components 4 have a central hole 14 with an inner thread 15 at the lower end and an embedded pin 10 with an outer thread 16 extending the upper end of the column component 4, the outer and inner thread having the same diameter. The support 2 is provided with a hole 17 which is slightly larger than the outer thread 16 of the column component but smaller than the diameter of the column component so that the support 2 can be placed on top of the column component 4 with the hole 17 around the thread 16. Next, a second column component 4 is screwed on top of the first column component. , thereby fixing the carrier 2. Instead of the second column component, the carrier can be fixed with a nut 5. The nut is provided with a hole 18 and an internal thread 19 corresponding to the inner thread 15 of the column component 4.

Figure 4 illustrates the skeletal assembly process. On a first column component 20 (Fig. 4a) with external thread 16, a carrier 2 (Fig. 4b) is placed, then a second column component 21 (Fig. 4c) is placed on top of the first column component 20 and screwed on (Fig. 4d), after which the carrier 2 is fixed. between the column components 20 and 21.

Figure 5 shows the assembly level by level of a simple example of a furniture system with countertop according to the invention. In the first level (Figure 5a), which constitutes the unit cell of the furniture system, a first carrier 100 is placed on top of two column components 101, 102. In the triangular basic structure, a third column component 103 with a spacer 104 forms the basis for the next level, which is on top of the first level. is shown in Figure 5b. The second level is comprised of three column components 201,202, 203, a spacer 204 disposed on one column 201, and a carrier 200 connecting the other two columns 202, 203. Correspondingly, the third (Figure 5c) and the fourth level (Figure 5d) built up. The fourth level is also completed with three nuts 301, 302, 303 (Figure 5e), which also provide support for a countertop 22 mounted on top of this frame (Figure 5f). It should be noted that the three nuts 301, 302, 303 have the same level and that the drawers are all horizontal, using spacers in the four levels. It is possible to provide the nuts with a non-slip surface so that a countertop resting on the nuts can be securely placed on the skeleton.

Figure 6 outlines some top view examples of furniture systems of the invention. It should be noted that the kites shown are arranged at different levels.

Figure 7 shows examples of furniture systems according to the invention with triangular shelves. In Figure 7a, one triangular plate / shelf 23 is used in one level, while in Figure 7b three triangular plates / shelves 24, 25, 26 are shown in the same level. Shelves 24, 25, 26 rest on the two kites 27, 28, one of which corresponds to two unit lengths. In Figure 7a, the shelf 23 rests partly on the carrier 29 and partly on the spacer 30.

Figure 8 shows a corner 31 of a triangular shelf / plate 32 with a circular arcuate recess 33. The plate of the figure rests on the carrier 1. The recess 33 of the plates has several functions; partly, it causes the plate 32 to be placed on the skeleton despite the column 4 or nut 5 in the corner, whereby plates such as 24, 25, 26 shown in Fig. 7b can be seated tightly together, and it prevents the plate from sliding laterally down from the skeleton, and in part it causes the plate 23 shown in Figure 7a to rest on the edge of a spacer 30.

Figure 9a shows a corner of the skeleton with countertop 22 and the nut 5, 303 serving as support for the countertop 22. In this preferred embodiment, the countertop 22 is provided with a hole 51 in which the nut 5 is placed when the countertop 22 is placed on the skeleton. for example, resting on the underlying supports 2, as shown in Figure 9b, or on the edge of the underlying spacers 3, as shown in Figure 9a. The holes 51 in the countertop 22 have the advantage that the countertop 22 can be placed in the skeleton so that it can be built on the skeleton at a height above the countertop 22. In Figure 9c a special design is shown in which the nut 52 is provided with a disc-like upper portion 53 having a diameter greater than the hole 51 in the countertop 22. Such a nut 52, when placed in the hole 51 of the countertop 22 and screwed into the underlying column 4, will not only ensure that the countertop 22 does not may slide laterally on the skeleton, but also prevent the tabletop 22 from being unintentionally lifted free of the skeleton.

Figure 10 shows an example of an embodiment of a foot 31 to the lower part 33 of a column 32 of the furniture system where a furniture wheel 34 is arranged. Furniture wheels 34 can be placed under all columns of the skeleton or only under some of the columns. Alternatively, this foot 31 may be constituted by the lower portion 33 in combination with an assembly screw, as described initially, or the foot 31 may be formed with a wider bottom support, for example, of plastic, to exert less pressure on the backing on which the skeleton stands, and thereby sparing this.

Figure 11 shows an example of a furniture system in which the base area of the unit cell is a straight-legged, right-angled triangle whose corners comprise, for example, columns 35, 36 and 37. The shown drawers 38 between the two columns 35 and 36 and the carrier 39 between the columns 35 and 37 has a length equal to the unit length, while the carrier 40 connecting columns 36 and 37 has a length corresponding to the unit length multiplied by V2 (square root of 2).

Figure 12 shows a removable space 54 which is placed in a skeleton depicted with four column components 5 and four supports 2. For example, a square base skeleton can be formed by assembling two 90 ° - 45 ° - 45 ° triangles. The removable compartment comprises two side walls 55 and a back wall 56 to which the two sidewalls are connected by hinges 57. The removable compartment 54 can thus be incorporated into the skeleton and dismantled from the skeleton without the skeleton having to be separated. . In the removable compartment 54, rails can be mounted on the side walls for use in drawers. The removable compartment can also be provided with top and bottom, as well as a hinged door to thereby form a cabinet.

Figure 13 shows a partition 58 mounted between two column components 5 and resting on a support 2. The circular recess 59 in the partition 58 ensures that the partition 58 is stably mounted in the skeleton.

Figure 14 shows a cross-section of a partition 58 resting on a carrier 2 or a spacer 3. The partition 58 is provided with an angled recess 61 to allow space for a shelf 60 to be supported on the carrier 2 and the spacer 3 respectively. .

More designs are possible than shown in the figures. Thus, the kites may be provided with built-in lamps, for example halogen lamps. Furthermore, the drawers can be provided with upholstery so that they are suitable as footrests.

Furthermore, in the design of the skeleton, it is possible for several layers to be laid on top of each other in a single level on a column component. This provides greater freedom in the design of a skeleton, since from this one column component at this level several kites can be projected in different directions.

The plates / shelves may have different shapes as mentioned above. In addition, the plates may also be further shaped in various ways, for example with an edge, so that objects are prevented from sliding or rolling down of the plates. Such a plate will also be suitable as a tray that can be removed from the skeleton. The boards can also be padded to make them suitable for stools, footrests or bricks.

The various components for the skeleton and other components such as drawers, partitions or sheets can be made of different materials such as wood, plastic, glass or metal and in different colors.
