Description

Furniture system, composite panel, furniture system setup and assembly method

The present invention relates to a furniture system according to the preamble of patent claim 1, a composite panel according to patent claim 13, a furniture system device according to patent claim 16 and an assembly method according to patent claim 21.

Technological background

Furniture systems and assembly methods for furniture systems are known from the prior art.

The US 2005/0127802 A1 discloses a furniture system, this furniture system having a large number of individual elements. The disadvantage of this well-known solution is that the furniture system consists of many individual parts and, in the absence of pre-assembled units, the assembly of the furniture promises an “IKEA experience” with long assembly times. The furniture side parts (especially the back wall) play an important role in the stability of the furniture system.

The WO 2018/031868 A1 discloses a furniture system with rear wall rails and a plurality of one-piece and closed frame elements, wherein the rear wall rail extends from a first frame element to at least one second frame element and is in a detachable operative connection with at least the first and second frame elements. The rear wall rails are C-shaped and the connection between the rear wall rail and frame elements essentially comprises T-shaped slot blocks and screws which are screwed through the frame elements into the slot blocks.

The disadvantage of this known solution is that the connection between the rear wall rail and the frame elements is complex and requires complex assembly. In addition, external cladding elements are necessary to stabilize the furniture system against shear forces parallel to the building wall. These cladding elements therefore run continuously over the entire length of the furniture. This prevents the furniture system from being subsequently expanded to include a single module, for example with a door.

Presentation of the invention

One object of the invention is to avoid at least one of the disadvantages of the prior art; in particular, a furniture system and an assembly method are to be created which enable a simple, modular furniture system which is intrinsically is stable and reduces the use of materials to a minimum. In addition, a composite panel and a furniture system device are to be created, which enable the furniture to be assembled quickly and easily, as well as enable later expandability and/or adaptation/modification of the furniture system.

This task is solved by the features of the independent patent claims. Advantageous further developments are set out in the figures and in the dependent patent claims.

A furniture system according to the invention with a modular frame structure comprises a plurality of frame elements and at least one rear wall fastening rail, which extends from a first frame element to at least one second frame element and is in a detachable operative connection at least with the first and the second frame element, at least the first frame element has a first and a second support element, which are aligned perpendicular to the first frame element. There is at least one front element which is detachably arranged on the first and second support elements.

The modular furniture system can be assembled easily and conveniently, with the individual elements being positioned step by step on the rear wall mounting rail. The rear wall fastening rail can be placed loosely on a surface or can be arranged on a building wall by a user, for example a drywaller. The drywaller can therefore attach at least the first element of the furniture system to the building at a very early stage, so that further planning of the interior design is simplified. The buyer of the apartment or house can have a say at an early stage and have the furniture system planned at the time of building planning, so that later planning steps can be avoided and there is a significant time saving in the overall planning. The rear wall mounting rail, the frame elements and the support elements form a 3-dimensional furniture system, whereby the interior space formed in the furniture system can be divided into several interior spaces using additional frame elements. The at least one removable front element enables easy and comfortable access to the one or more interior spaces of the furniture system, so that, for example, the assembly of furniture fittings and/or the arrangement of shelf elements in the already existing, possibly semi-finished, furniture system is simplified. Subsequent height positioning of furniture fittings and/or shelf elements is easily possible. The at least one removable front element not only enables easy, direct access to the frame elements, but can also be part of the external appearance of the furniture system, so that additional elements for covering the front elements or covering a large area of them, for example with door fronts, can be dispensed with. This opens up new design accents for furniture system furnishings, for example, by consciously combining metal and concrete surfaces. Due to the intrinsic stability of the modular furniture system, material can be saved on the side paneling, so that overall environmental influences are sustainably minimized. For example, a furniture back wall or furniture base behind or below drawers can generally be dispensed with. In addition, the furniture system allows the greatest possible freedom in terms of the external design and appearance of the furniture.

At least the aforementioned elements of the furniture system can be transported individually, if necessary individually packaged, so that the transport costs are significantly minimized due to the resulting lower transport volume. The furniture system is intrinsically stable and does not rely on the furniture paneling (side parts) for stabilization.

The at least one front element has connecting sections with which the at least one front element is removably arranged on the support elements on the first frame element. The connecting sections can include or accommodate positive connecting elements, such as plug-in connections, and/or non-positive connecting elements, such as screw connections, so that the front element can be arranged reproducibly and with a high degree of accuracy on the first frame element. In particular, this makes it possible to create an aesthetically beautiful furniture wall finish, so that additional panels can be avoided and significant material savings are achieved.

Advantageously, at least one frame element additionally has a third support element, so that the furniture system can be constructed higher and more stable. For this purpose, a further front element can be present, which is detachably arranged on the second and third support elements. The further removable front element is vertically spaced from the at least one front element and enables easy and comfortable access to the one or more interior spaces of the furniture system, so that, for example, the assembly of furniture fittings and / or the arrangement of shelf elements on different floors in the furniture system are easily possible.

Preferably, at least one positioning unit is present for positioning the at least one front element on the first frame element, so that the removable front element can be reproducibly positioned on the first frame element. The at least one positioning unit is advantageously arranged on the first frame element and has at least one, in particular two, positioning projections. The one positioning projection or the two positioning projections are designed to engage in the connecting sections on at least one front element. At least one positioning projection is advantageously designed in a Z-shape in order to hold the at least one front element in a clamping manner. The rear wall fastening rail preferably has a plurality of spaced-apart marking elements for arranging the frame elements in a position-determined manner. This means that the width and the division in the furniture system can be individually adjusted, thereby significantly stabilizing the furniture system in width and height. As a result, the furniture system has a high degree of flexibility in design, with different sized frame elements being able to be arranged on the rear wall mounting rail. The modular structure allows the design of the furniture system to be changed subsequently. Such rear wall mounting rails can be produced cost-effectively in batch sizes of 1 using today's laser cutting bending machines.

Preferably, at least one marking element has a receptacle for arranging the first frame element, so that a direct arrangement of the frame elements in the area of the markings is possible. The rear wall fastening rail can be designed as a U-profile, so that the rear wall fastening rail itself is stable and solid due to the 3-dimensional U-profile. This makes assembly, for example, easier and reproducible.

In particular, the receptacle is designed to accommodate the first frame element in a self-supporting manner, so that the first frame element is stable in balance on the rear wall fastening rail due to its own weight. Additional complex assembly aids can therefore be avoided.

The receptacle preferably comprises at least one notch, with the first frame element engaging at least in sections in the at least one notch. The first frame element, and in particular the rear wall fastening rail, can be designed with a wall thickness of a few millimeters, 1 to 8 mm. When assembled, the thin-walled first frame element engages in the notch and is clamped in the notch so that it is held in a self-supporting manner. In particular, the notch can have a taper in the direction of the U-profile of the rear wall fastening rail. This means that no assembly aids are necessary and assembly can easily be carried out by anyone.

The rear wall fastening rail preferably has at least two fastening devices for fastening the rear wall fastening rail to a building wall, which are designed in particular as elongated holes. The rear wall mounting rail thus enables simple and reproducible alignment or leveling of the furniture system in all three spatial directions.

Preferably, at least the first frame element has at least one fixing device for fixing to the rear wall fastening rail. The fixing device can be a include frictional or non-positive fixing elements, so that reproducible arrangement is possible.

The first frame element is preferably designed in several parts. In addition to the first and second support elements, the first frame element can include further support elements, so that the overall stability of the furniture system is improved.

At least one frame connecting element is preferably present, which connects the first frame element to the second frame element. The frame connecting element creates a cross connection that runs parallel to the rear wall mounting rail and provides additional stability in the horizontal plane of the furniture system. The frame connecting element has connecting elements for connecting to the frame elements, which are advantageously designed as hooks and are arranged on the front side of the frame connecting element. Such hooks engage in the thin-walled structure of the frame elements and enable a stable construction of the furniture system.

Preferably, at least the first frame element has at least one first fitting carrier receptacle for arranging a fitting carrier. The fitting carrier receptacle can be an opening into which the fitting carrier can be inserted so that it can be easily installed. The first frame element advantageously has at least one second fitting carrier receptacle for arranging the fitting carrier. This means that the fitting carrier can be positioned at several positions in the interior of the furniture system. In particular, the second frame element also has one or more fitting carrier receptacles.

In particular, the first fitting carrier receptacle is arranged immediately adjacent to the second fitting carrier receptacle. This makes it possible to position the fittings carriers closely together.

Preferably, the at least one front element has at least one third fitting carrier receptacle for arranging a fitting carrier. The at least one front element therefore not only serves as a stability-providing element in the furniture system, but also stabilizes the fitting supports in the interior of the furniture system. Arranging the fittings carrier and other elements in the interior of the furniture system can be easily carried out from the front without having to make any other structural changes to the furniture system.

Preferably, at least one first fitting carrier is present, which has at least one first fitting carrier fixing device for arranging the first fitting carrier on the first frame element. The fitting wearer can use a hook first Have fitting carrier fixing device, which can be inserted into the first fitting carrier receptacle and wedges itself with the first frame element in the inserted state. Alternatively or additionally, the fitting carrier can be arranged in a form-fitting or non-positive manner in the fitting carrier receptacle. Such a fitting carrier is also according to the invention as an independent element, independent of the furniture system.

In particular, the first fitting carrier is arranged on the first frame element, so that the furniture system is additionally stabilized in its height-depth plane. The first fitting carrier is preferably arranged on the front side of the first frame element. This means that connectable furniture fittings can be positioned easily and without obstacles on the first fitting carrier. It is easy to subsequently change the equipment in the furniture system, as furniture fittings or fitting elements from different manufacturers can be mounted on the first fitting carrier. For example, it is easy to attach stabilizing crosses to drawers or shelves.

Preferably, the first fitting carrier has at least one second fitting carrier fixing device for arranging the first fitting carrier on the at least one front element. In particular, the first fitting carrier is arranged on the at least one front element. The fitting carrier is thus arranged at two different positions in the interior of the furniture system, so that stability is improved. The fitting carrier fixing device advantageously comprises a projection or a hook, which engages in the at least one front element, so that the at least one front element stably supports the projection or the hook and at the same time can be easily removed from the furniture system from the front.

The first fitting carrier is preferably arranged on the front side of the at least one front element. The first fitting carrier is therefore arranged not only on the front side of the first frame element, but also on the front side, i.e. at the opposite end of the fitting carrier, on the at least one front element. This further improves the stability in the furniture system.

The first fitting carrier preferably has a fitting receiving section, which extends in particular in the direction of a horizontal plane. This means that fittings from different manufacturers can be easily mounted on the fitting carrier and are held securely in position.

The fitting receiving section preferably has a fitting positioning device, which particularly preferably comprises at least one elongated hole. This means that any furniture fitting can be positioned on the fitting carrier. The elongated hole enables stepless positioning along the horizontal plane on the fittings carrier. Preferably, the first fitting carrier has a hinge receiving section, which extends in particular in the direction of a vertical plane and optionally has a further elongated hole. This means that hinge mounts on the fittings carrier can also be positioned continuously.

Alternatively or additionally, a hinge receiving element is present, which is or can be arranged at least on the first frame element. Own hinge receiving elements enable hinges to be arranged easily and directly adjacent to the support elements of the first frame element, so that the door movement of a door on the furniture system is stable over the long term.

Preferably, at least the rear wall fastening rail has a metal element or is made of metal. This makes it possible to easily electrify the furniture system. The metal element leads the negative pole of a low-current direct current source to a consumer and therefore only one line is required for the positive pole, for example to provide interior lighting in the furniture system. In particular, LEDs, sensors or actuators can be provided as consumers, so that the furniture system can be upgraded to an intelligent furniture system. Alternatively or additionally, at least one frame element has a metal element. Alternatively or additionally, at least one fitting carrier has a metal element. The metal elements in the furniture system also lead to improved resistance to moisture, so that the furniture system can also be used outside of the weather-protected living space, for example as an outdoor kitchen, with the appropriate choice of materials (aluminum, stainless steel) or appropriate surface finishing (galvanizing, paint).

Side panels are advantageously present, which are arranged at least on the outside of the first frame element. Such side panels enable an individual aesthetic design of the furniture. For example, the side panels can simply be pushed laterally into the frame elements so that they are self-supporting.

A composite panel according to the invention, in particular for a previously described furniture system, comprises a carrier material, at least one filling layer and a casting layer, the casting layer comprising a material from the group of concrete, plaster, papier-mache or casting resin. For concrete or papier-mache, a layer thickness of 1 to 5 mm is preferably provided as the casting layer. In the case of plaster, a layer thickness of 1 to 7 mm is preferably provided as the casting layer and in the case of casting resin, a layer thickness of 0.1 to 20 mm, in particular 1.5 mm, is provided as the casting layer. Such composite panels have a good sustainability record (especially compared to chipboard-based panels for panels and fronts). In particular, new design options open up in furniture construction and in living space design (e.g. suspended ceilings with the composite panels described here), whereby a good feel is achieved when using natural casting materials (especially compared to laminate-based imitations). In addition, a wide range of surface structures are possible, for example by introducing textures into the casting surface of the casting layer. Such composite panels have good processability, such as easy cutting of panel material with ordinary carpentry construction machines, such as saws, as well as easy connection to other furniture elements (using screws, blind rivets, gluing). Simple and reproducible reworking of the casting surface of the casting layer is made possible and production errors (scratches, holes) in the casting layer can be corrected. In addition, a casting surface can be further refined (sealing, oiling, painting over). The casting layer creates a solid and resistant surface of the composite panel, especially on the furniture system. Such composite panels can serve as side walls and side panels in the furniture system described here.

The filling layer preferably comprises a material from the group of corrugated cardboard, Styrofoam or foam. For cardboard, a layer thickness of 2 to 20 mm, in particular 6 mm, is preferably provided as the filling layer. The use of recycled materials (corrugated cardboard or cardboard) and/or natural materials (concrete) ensures that materials are used sustainably. In addition, furniture systems can be produced with less weight and thus savings in transport costs are possible. In addition, good handling is possible due to the reduced weight (especially compared to chipboard-based panels and fronts).

The carrier material is preferably flat and can have bent-up tabs on the edge, so that the filling layer can be reproducibly positioned and the potting layer can be easily filled. In addition, the edges of the composite panel are protected from mechanical and chemical influences by the tabs. The carrier material can be 0.4 to 5 mm, in particular 1 mm, thick and include or consist of aluminum, stainless steel, plastic or other equally rigid materials. This enables a simple and stable connection to supporting elements in the furniture system, such as the first frame element. The carrier layer can be glued, riveted and/or screwed to the furniture system. Furniture fittings or handles can also be stably positioned on the carrier layer in this way.

The filling layer can be constructed in one or more layers and significantly reduces the weight of the composite panel, while improving stability. Corrugated cardboard is therefore provided as the preferred filling layer. Preferably, a reinforcing layer is present between the filling layer and the casting layer or within the casting layer, which in particular comprises a grid, a net, a mat or fibers. The fibers may include textile fibers or glass fibers. The reinforcement layer is preferably 0.1 to 1 mm thick. The reinforcing layer stabilizes the casting layer and prevents cracks from forming in the casting layer.

An adhesive layer is preferably present between the carrier material and the filling layer, so that their adhesion to one another is improved. For example, a two-component resin, such as epoxy resin, can be used as the adhesive layer, as this is easy to process and is particularly heat-stable.

A furniture system device according to the invention comprises a first frame element, on which at least a first fitting carrier is arranged and on which at least one front element is removably arranged. The furniture system device is part of a modular system for a furniture system and is sold preconfigured and, if necessary, individually packaged and transported, so that transport costs are significantly minimized due to the resulting lower transport volume.

The first frame element preferably has at least one fixing device for fixing to a rear wall fastening rail and is preferably designed in several parts. The fixing device can comprise a frictional or non-positive fixing element, so that reproducible arrangement is possible.

Preferably, the first frame element has at least one wall receptacle for receiving side walls. The wall receptacles can be designed as openings into which projections of the side walls engage and hold them stably. A composite panel as described above advantageously serves as the side wall. In particular, a side wall can also include an electrical circuit board with conductor tracks, so that the electrification of the furniture system is intrinsically simplified.

In particular, at least one first side wall is arranged on the first frame element, which preferably has an engagement device, in particular projections, for holding the first side wall in the wall receptacle of the first frame element. A composite panel as described above can be provided as the first side wall.

Preferably, the first fitting carrier has at least one first fitting carrier fixing device for arranging the first fitting carrier on the first frame element. The fitting supports described above are simply arranged on the first frame element and can be delivered inexpensively as a preconfigured element. In particular, the first fitting carrier has at least one second fitting carrier fixing device for arranging the first fitting carrier on the at least one front element.

Preferably, at least one composite panel, as described above, is present as a front panel.

An assembly method according to the invention for assembling a furniture system with a modular frame structure comprises at least the following assembly steps, in particular in the following order: a) providing a rear wall fastening rail with several marking elements; b) arranging at least a first frame element or at least a first furniture system device on at least one of the marking elements of the rear wall fastening rail; c) receiving the first frame element or the first furniture system device on a receptacle of the rear wall fastening rail, the receptacle being in particular designed to accommodate the first frame element or the first furniture system device in a self-supporting manner, the first frame element or the first furniture system device preferably engaging at least in sections in the at least one receptacle . d) Arranging a front element on the first frame element or on the first furniture system device, wherein the front element preferably fixes at least one fitting carrier.

The modular furniture system can be assembled easily and conveniently, with the individual elements being positioned step by step on the rear wall mounting rail. The rear wall fastening rail can be placed loosely on a surface or can be arranged on a building wall by a user, for example a drywaller. The at least one removable front element enables easy and comfortable access to the one or more interior spaces of the furniture system, so that, for example, the assembly of furniture fittings and/or the arrangement of shelf elements in the already existing, possibly semi-finished, furniture system is simplified. Subsequent height positioning of furniture fittings and/or shelf elements is easily possible. The at least one removable front element not only enables easy, direct access to the frame elements, but can also be part of the external appearance of the furniture system. The shelf elements or furniture fittings can be assembled from the front by the user in just a few steps and in a very short time. The furniture system device is part of a modular system for a furniture system and is sold preconfigured and, if necessary, individually packaged and transported, so that transport costs are significantly minimized due to the resulting lower transport volume.

Preferably, at least one fitting carrier is arranged on the first frame element, or is present on the first furniture system device, with in particular a fitting or a hinge being positioned on the fitting carrier. The fitting carrier can easily be positioned from the front by a user in the interior of the furniture system.

Preferably, at least after step b), at least one further frame element or another furniture system device is arranged on at least one further marking element of the rear wall fastening rail. This means that the furniture system can be easily assembled or expanded later.

In particular, at least one frame connecting element is then arranged. This provides improved stabilization of the first and second frame elements.

Preferably, the rear wall fastening rail is fastened to a wall, for example a building wall, in step a). The drywaller can therefore attach at least the first element of the furniture system to the building at a very early stage, so that further planning of the interior design is simplified. The buyer of the apartment or house can have a say at an early stage and have the furniture system planned at the time of building planning, so that later planning steps can be avoided and there is a significant time saving in the overall planning.

Alternatively or additionally, after step c), the rear wall fastening rail is attached to a wall with the first frame element or the first furniture system device. This improves the flexibility of the furniture system and the furniture system can be easily installed in existing buildings.

Preferably, after step e), side walls are arranged on the first frame element or on the first furniture system device. This protects the interior of the furniture system from dirt or UV light influences.

Preferably, at least one electrical operating device is arranged after step c). This allows lighting, sensors and actuators to be integrated into the furniture system in order to expand the furniture system into an intelligent furniture system. For example, the furniture system can be equipped with LoT technology. Preferably, at least after step c), at least one composite panel as described above is arranged on the furniture system or on the first furniture system device. This means that the furniture system is equipped with light, natural materials.

Implementation of the invention

1 to 13 show a furniture system 100 with a modular frame structure 101 comprising a plurality of frame elements 120a-120d and rear wall fastening rails 110, 110a, which extend from a first frame element 120a to further frame elements 120b-120d and with the frame elements 120a-120d are in a detachable operative connection, the frame elements 120a-120d having at least support elements 122 which are aligned perpendicular to the frame elements 120a-120d. The frame elements 120a-120d have front elements 125a-125e, which are detachably arranged on the respective support elements 122 - see in particular Fig. 7. The frame elements 120b-120d each additionally have a third support element 122, so that the furniture system 100 is also higher and more stable can be built. There are further front elements 125e, which are detachably arranged on the second and third support elements 122. The further removable front elements 125e are vertically spaced from the respective front elements 125b-125d on the respective frame element 120b-120d - see Fig. 1 The modular furniture system 100 can therefore be assembled easily and conveniently, with the individual elements being positioned step by step on the rear wall fastening rails 110, 110a. The rear wall fastening rails 110, 110a, the frame elements 120a-120d and the support elements 122 form a 3-dimensional furniture system 100, with the interior space formed thereby in the furniture system 100 being divided into several interior spaces using further frame elements 120b, 120c. In this embodiment, the frame elements 120a-120d and the rear wall fastening rails 110, 110a consist of a bending sheet with a wall thickness of 1.5 mm. The frame elements 120a-120d are designed in several parts. In addition to the first and second support elements 122, the frame elements 120b-120d include further support elements 122. The support elements 122 are positively and non-positively connected to the frame elements 120a-120d and have connecting sections 123 for this purpose, which are essentially designed as an L-shape.

2 and 3 show the rear wall fastening rail 110 with a plurality of spaced-apart marking elements 115 for arranging the frame elements 120a-120d in a position-determined manner. The rear wall fastening rail 110 has fastening devices for fastening the rear wall fastening rail 110 to a building wall, which are designed as holes 111 and elongated holes 114. The marking elements 115 have a receptacle 116 for arranging the frame elements 120a-120d, so that a direct arrangement of the frame elements 120a-120d in the area of the markings 115 is possible. The rear wall fastening rail 110 is designed as a U-profile, so that the rear wall fastening rail 110 itself is stable and solid due to the 3-dimensional U-profile. The receptacles 116 are designed as notches 117, with the frame elements 120a-120d engaging in the notches 116 at least in sections. The thin-walled frame elements 120a-120d are clamped in the notches 117 so that they are held in a self-supporting manner. The notches 117 have a taper in the direction of the U-profile of the rear wall fastening rail 110. The receptacles 116 are thus designed to accommodate the frame elements 120a-120d in a self-supporting manner, so that the frame elements 120a-120d are kept stable on the rear wall fastening rail 110 in balance due to their own weight - see FIGS. 4 to 6. The rear wall fastening rail 110 has a connecting sleeve 112 , such as a press-in nut. The frame elements 120a-120d are at least partially screwed to the connecting sleeve 112 of the rear wall fastening rail 110 using a screw 113 - see Fig. 5.

7 to 10 show the first frame element 120a with the removable front element 125a as an example structure for the further frame elements 120b-120d. The front element 125a has connecting sections 126, with which the front element 125a is removably arranged on the support elements 122 on the first frame element 120a. The Connecting sections 126 have positive connecting elements 127 and non-positive connecting elements 128, so that the front element 125a can be arranged reproducibly and with a high level of accuracy on the first frame element 120a. In the embodiment shown, the positive connecting element 127 is an opening 127a.
