Abstract

A piece of furniture (10) in the form of a self-supporting spatial hollow structure (9) with a cover plate (11) and several side plates (12a-12d), each of the plates (11, 12a-12d) being made up of a plurality of webs (13a-13c) is constructed with openings (14a - 14c) in between and is connected to at least three adjacent panels along a common edge (15a, 15b), the webs being irregularly shaped and distributed over the panels in a chaotic pattern (16a, 16d), wherein different webs have different lengths, widths, thicknesses than other webs, and wherein the webs are arranged with different angles of their web axes (20) with respect to a plate edge on the respective plate, is characterized in that the pattern of webs with intervening openings is designed on all panels in such a way that the local patterning of each panel on all of its edges seamlessly integrates with the respective pattern of the Edge with the plate connected to the adjacent plate passes. In this way, stress peaks can be avoided and the force dissipation of the weight of a body on the piece of furniture can be diverted over the entire side panels.

Description

The invention relates to a piece of furniture in the form of an inner carcass-free, self-supporting spatial hollow structure without a substructure with a cover plate and several side panels, each of the panels being made up of a plurality of webs with openings in between and connected to at least three adjacent panels along a common edge , wherein the webs are irregularly shaped and distributed in a chaotic pattern over the plates, with different webs having different lengths, widths, thicknesses than other webs, and wherein the webs are arranged with different angles of their web axes with respect to a plate edge on the respective plate .

The term “edge” on bodies delimited by planar surfaces is generally understood to mean that distance at which two delimiting surfaces meet. (Pointed) "corners", however, are the meeting points of several edges in space.

Background of the invention

The invention relates in particular to seating furniture, preferably stools, with the aforementioned features.

Such seating furniture is available on the market (see references [1] and [2]). In this seating furniture, a frame is formed on the common edges of the side panels. The bars are located on each side plate within the frame. The webs have a chaotic web structure which extend over the entire side plates (see reference [1]) or parts of the side plates or the cover plate (see reference [2]).

Stools with a lattice or buttress to support the seat have been known for thousands of years, including from Egypt (reference [3]). The struts of these stools are horizontal, vertical or diagonal.

Stools are used for artistic arrangements, for example in the form of folding stools made of sheet aluminum with rod-like, networked, transparent structures (reference [4]) with two side panels, a cover panel and a base panel.

Struts are also known from everyday objects used in the household, for example laundry boxes (reference [5]). Laundry boxes of this type have, in particular, side panels, bottom and top surfaces made of lattice-shaped structures with square or rectangular openings. The lattice-shaped structures are designed regularly.

Such regular grid-like structures with rectangular recesses are also known for stools (reference [6]). Such stools are designed in particular in the form of a cube.

There are also stools and side tables available on the market made of aluminum that have four side panels with curved, crossed bars (reference [7]). A frame runs along the common edges of the side panels, within which the webs are arranged on each side panel. Openings of different sizes, but regularly arranged, are formed between the webs.

The Lambert catalog (reference [8]) includes pieces of furniture in the form of side tables and stools. In particular, the "Papua side tables" (p.117) and "Papua stool" (p.135) shown there are created by the fact that so-called "bamboo split", which is a natural, strip-shaped, is not a uniform material is braided over a body. In contrast to this, a generic piece of furniture of the type defined at the outset has a self-supporting spatial hollow structure that is free of the inner body and does not have a substructure and consists exclusively of panels. These are all made up of a large number of webs with openings in between and each connected to at least three adjacent plates along a common edge. Neither the "Papua Side Tables" nor the "Papua Stool" from reference [8] have such plates or edges.

Wicker furniture, in particular rattan stools and side tables, are also known from reference [9]. These pieces of furniture also have neither plates nor edges in the sense of the generic piece of furniture. The rattan bars are neither irregularly shaped nor distributed over the panels in a chaotic pattern. Different webs also do not have different lengths, widths, and thicknesses than other webs, but are essentially uniformly shaped. Finally, the webs of the rattan furniture according to reference [9] are not arranged with different angles of their web axes with respect to a board edge on the respective board and therefore cannot be compared with a generic piece of furniture.

The stools, which have a chaotic bar structure (cf. references [1] and [2]), are characterized - apart from and in addition to their aesthetic creation - in their actual physical properties due to this chaotic bar structure by a comparatively high area moment of inertia and a this structure caused a reduction in force peaks - at least to a certain extent.

The disadvantage of all previously known generic pieces of furniture that have such a chaotic web structure, however, is that due to the different stiffness of frames and webs in the transition area from the frame structure to the web structure, possible stiffness jumps and thus stress peaks occur under load, which can lead to breaks in the webs . Furthermore, the weight of a user of the piece of furniture who sits on the piece of furniture, largely diverted via the frame, so that this experiences the main load. Another disadvantage is that decorative figures on the side surfaces are cut off laterally by the frame.

Object of the invention

In contrast, the present invention is based on the - viewed in detail, relatively demanding - object of providing a generic piece of furniture with those defined at the beginning, which has a chaotic web structure on side panels, with stress peaks being avoided, but with a weight acting on the furniture over the entire side panels , not just through a framework. It is a further object of the invention to design such a piece of furniture reproducibly with technical means in such a way that figures and patterns of the side surfaces - in particular also visually - are not cut off laterally.

Brief description of the invention

This object is achieved by the present invention in a surprisingly simple and effective way in that the patterning of webs with openings in between on all plates is designed so that the local patterning of each plate on all of its edges seamlessly into the respective pattern of the above the edge with the plate connected to the adjacent plate passes. Due to the seamless continuation of the pattern from one side panel to an adjoining side panel over a common edge, there is no transition from a frame to a chaotic, irregular web structure, as is the case with pieces of furniture known from the prior art. This avoids stiffness jumps and stress peaks, which in such a transition area due to the different stiffness of the frame and the irregular Bar structure can occur. The side plates have comparable stiffnesses in different areas, especially at the edge. Furthermore, the force dissipation of a weight acting on the piece of furniture takes place over the entire side panels and not mainly over the frame. Furthermore, figures on the side surfaces are not interrupted or cut off by a frame, since these are continued over the edges of the side surfaces.

For the production of the self-supporting hollow piece of furniture according to the invention, however, no substructures, in particular no body parts or molded parts, are required inside. The piece of furniture consists of self-supporting panels and is neither surrounded by a wrapped or glued material nor is it constructed with multiple shells.

Due to the technical measures according to the invention described above, in addition to the improved physical properties, new aesthetic effects can also be achieved on the finished piece of furniture:
A basic idea of the present invention is the circumferential running of a pattern with geometric or freely invented shapes over all edges - and incidentally also corners - on a hollow piece of furniture with a self-supporting construction (regardless of whether it is designed as a stool, chest of drawers or e.g. With this teaching of the invention, a constructive three-dimensional body can therefore be created, which in its optical view is no longer necessarily perceived in its original three-dimensional form, for example as a cuboid or cube, due to the passage through the patterns, but rather as a filigree spatial pattern, whereby a "spatial overall picture" of the pattern is visible to the viewer.

The pattern is cut, sawn or engraved into the load-bearing structural parts of the furniture according to the invention, in particular by means of laser cutting or laser engraving. The actual patterns are developed using an elaborate relative arrangement of geometric or freely invented shapes and transferred to a CAD drawing program. A special technical feature is depending on the pattern (regardless of whether it is geometrical or fictitious shapes) the pattern running through the connections between the side parts, which, due to the individual part shape of, for example, a cuboid or cube, in the manufacturing process in a "base plate" are interrupted or are apart. Incidentally, the finished piece of furniture can stand on such a base or plinth plate, but this does not necessarily have to be, since sufficient stability can also be achieved by means of the side and cover plates alone.

A mechanical connection of the individual panels that is not visible from the outside can be achieved by appropriate gluing, but also by edge and corner connections on the inside of the hollow body, for example with light metal angles.

Preferred embodiments and developments of the invention

The piece of furniture according to the invention is generally made up of flat, preferably rectangular, in particular square, triangular or generally plates with a polygonal surface. However, designs using plates with at least partially curved surfaces are also conceivable.

The outer three-dimensional shape of the piece of furniture according to the invention will be a cuboid, in particular a cube, in most of the embodiments, especially those which are particularly easy to manufacture. However, other geometrical designs of the spatial shape of the piece of furniture are also quite possible. Through the above-mentioned use of plates with curved surfaces, bulging or concave, possibly partially cause rounded designs. However, what is essential for the invention is always the presence of edges at the joints between different panels.

One class of advantageous embodiments of the piece of furniture according to the invention is characterized in that the piece of furniture is made in one piece. This brings about a better cohesion of the various side panels and the cover panel of the piece of furniture.

Embodiments of the piece of furniture according to the invention are particularly preferred which are characterized in that a miter is provided on the edges between two adjacent panels on each of the two surfaces, with the mitres of adjacent panels being firmly connected to one another when the furniture is installed. Miters of this type enable a stable connection through a stepless transition between separate adjacent panels.

The miters can be sawn with a 0mm special miter cut, in which material a thickness between 0.1mm and 0.5mm, preferably about 0.3mm, remains on the outer surface of the sawn miter. Such a miter is characterized by a comparatively low weight of the material with relatively high stability.

When several panels come together, the miter cut at the edge ends results in more or less pointed spatial corners pointing outwards.

In advantageous embodiments, the web axes can be formed by straight lines. Straight webs can be produced comparatively easily.

Embodiments of the invention are also particularly preferred in which the web axes run on curved curves, the web axes of different webs each having different local angles at the beginning or the end of a web are arranged on the respective plate with respect to a plate edge. Curvilinear webs can be used to connect several support points for a body on the piece of furniture that are not on a straight line.

Further embodiments of the invention are characterized in that the webs are designed in such a way that the pattern formed by the webs with openings in between them geometric patterns and / or plant and / or animal and / or human motifs, in particular enlarged cell cross-sections, and / or characters or reproduces lettering and / or logos and / or word-and-picture symbols.

Further advantageous embodiments of the invention are characterized in that the cover plate and the side plates have a plate thickness between 4 mm and 20 mm, preferably approximately 10 mm. With such a plate thickness, the piece of furniture has a comparatively high stability with comparatively little material consumption.

Embodiments of the invention are also particularly preferred in which the cover plate and the side plates are made from wood and / or from plastic and / or from metal, preferably by means of laser cutting processes. With these materials, the piece of furniture can be designed to be comparatively stable with a comparatively low weight. With the laser cutting process, complex bar patterns can be produced quickly and precisely and comparatively inexpensively.

In further embodiments of the piece of furniture according to the invention, the cover plate and / or the side plates have one or more engravings, which are preferably produced by means of laser engraving methods and in particular are designed so that at least one of the engravings generates a three-dimensional pattern, the corresponding local engraving patterning a plate seamlessly into each of its edges Engraving pattern of the adjacent plate connected to this plate via the edge passes over.

Further advantageous embodiments of the invention are characterized in that there is a base plate on the base of the spatial hollow structure opposite the cover plate, on which the side plates stand in the assembled state of the piece of furniture. The base plate ensures that the side plates are spaced apart from the floor surface and thus less wear on the side plates.

In advantageous embodiments, the base plate can have a shoulder running around the edge, which is arranged lower than the central surface of the base plate and on which the side plates stand in the assembled state of the piece of furniture. As a result of the shoulder, the side plates have a form fit with the base plate in the vertical and horizontal directions and are correspondingly more stable.

Further embodiments of the invention are characterized in that the piece of furniture is designed as a seating furniture, in particular as a stool or chair, as a showcase, as a cupboard, as a shelf, as a table, in particular as a standing desk, as a lamp holder or decorative element, in particular as a three-dimensional portrait.

• dass das Möbelstück aus den Plattenteilen der zunächst ebenen Ausgangsplatte durch Umbiegen (beziehungsweise Zusammenfügen/ Zusammenklappen) der Plattenteile längs ihrer Kanten in eine räumliche Form aufgerichtet wird;
• und dass die Kanten benachbarter Plattenteile fest miteinander verbunden werden, beispielsweise durch Verleimung.

The scope of the present invention also includes a method for producing a piece of furniture of the type according to the invention, which is characterized in that

• that a uniform starting plate is produced from solid plate material, preferably by means of a laser cutting process, the starting plate then having a plurality of webs with openings in between, the parts of the starting plate each being connected along a common edge with several adjacent parts of the starting plate, and The pattern of webs with openings in between on all plate parts is designed so that the local The pattern of each plate part at all of its edges merges seamlessly into the respective pattern of the adjacent plate part connected to the plate part via the edge;
• that the piece of furniture is erected from the plate parts of the initially flat starting plate by bending (or joining / folding together) the plate parts along their edges into a spatial shape;
• and that the edges of adjacent plate parts are firmly connected to one another, for example by gluing.

In the case of a piece of furniture produced using such a method, sudden changes in rigidity and stress peaks are avoided. Furthermore, the force dissipation of a weight acting on the piece of furniture takes place over the entire side panels.

The development of the pattern is usually carried out after considerations based on the "design" requirements. First, appropriate hand sketches are made and brought into conformity with the desired basic shape of the intended piece of furniture. At the end, the division is transferred and worked out in a suitable CAD drawing program. The parts cannot be defined before the final definition of what exactly is to be built for a piece of furniture. It can be the sides of a stool, but also e.g. the "lid" or bottom of an upright open shelf.

A preferred embodiment of this method is characterized in that mitres are attached along the edges of adjacent plate parts, which fit together geometrically with the respective adjacent mitres after the plate parts have been erected, whereby preferably the miter cuts are not made through the entire thickness of the respective plate part, but edge webs stop between adjacent plate parts. Miters of this type enable a stable connection through a stepless transition between separate adjacent panels.

Further advantages of the invention emerge from the description and the drawing. The features mentioned above and below can also be used according to the invention individually or collectively in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for describing the invention.

The present invention relates to an item of furniture in the form of a three-dimensional hollow structure with a cover plate and a plurality of side plates.

The Figures 1a to 1c show the piece of furniture in different isometric views. The Figures 2a and 2 B represent the piece of furniture with opened side surfaces. In Figure 3 a mesh representation of the flat panel for the piece of furniture is shown. The Figures 4a to 4f illustrate process steps for producing a miter for connecting panels of the piece of furniture along a common edge.

The piece of furniture 10 is in particular a piece of seating furniture and comprises a cover plate 11 and side plates 12a, 12b, 12c, 12d. Each of the plates 11, 12a-12d consists of webs 13a, 13b, 13c. There are openings 14a, 14b, 14c between the webs 13a-13c. The side panels 12a-12d are connected along common edges 15a, 15b to adjacent side panels 12a-12d. The webs 13a-13c are distributed in a chaotic, irregular pattern 16a, 16b, 16c, 16d over the respective side plate 12a-12d. The webs 13a-13c differ from one another in their Shape, length, thickness and / or width. The webs 13a-13c are arranged at different angles of their web axes 20 with respect to a plate edge 15a, 15b on the respective plate 12a-12d.

The item of furniture 10 according to the invention differs from items of furniture known from the prior art mainly in that at least some of the patterns 16a-16d formed by the webs 13a-13c on the edges 15a, 15b of a plate 12a-12d on an adjacent plate 12a - 12d pass over or be continued on the adjacent plate 12a - 12d. Such a transition 19 of a pattern 16a, 16b is for example in FIG Fig. 1a shown. The web axes 20 run on straight lines or on curved curves and are arranged at different local angles at the beginning or end of a web with respect to a plate edge 15a, 15b on the respective plate 12a-12d. In the assembled state, the side plates 12a-12d each stand with a plate shoulder 24 on a base plate (not shown).

The piece of furniture in the form of a cube is produced by unfolding the side panels 12a-12d, as in FIG Fig. 2a and 2 B shown. The transition of the patterns 16a, 16b at the panel edges 15a, 15b is formed in particular on all side panels 12a-12d and the cover panel 11, as in FIG Fig. 3 shown. The piece of furniture forms a hollow structure 9.

If you put the later connected edges together in the flat, unfolded state, they will fit together 100%; likewise the connection between the cover plate and the side parts.

The continuous arrangement of geometric or freely invented forms of the pattern in the finished, assembled piece of furniture creates a spatially continuous "image" that cannot be perceived as this when it is opened, for example Fig. 3 he sees.

The plates 12a-12d are connected to one another in particular by miters 25. To produce the miter 25, a plate 12 is first provided, as in FIG Figure 4a shown in a side view. A first miter cut 26a is made in the plate 12, in particular with a miter saw (see FIG Figure 4b ) . Then a second miter cut 26b is made in the plate 12, which runs at a 90 ° angle to the first miter cut 26a (see FIG Figure 4c ) . The plate piece 27 cut out in this way is removed. The plate 12 now has a right-angled inside corner 28 , as in FIG Figure 4d shown. A first and second plate part 29a, 29b on both sides of the inner corner 28 are folded towards one another (see FIG Figure 4e ) until the cut edges 30a, 30b of the plate parts 29a, 29b come to rest on one another at the inner corner 28. This creates the miter 25 (see Fig. 4f ). The cut edges 30a, 30b of the plate parts 29a, 29b can be connected to one another in an even more stable manner by gluing or by dowels.
