Description

The invention relates to a piece of furniture and its use, the piece of furniture having an inflatable, plate-shaped volume element.

The DE102012103948 discloses a body having an interior chamber that is inflatable with a gas. Furthermore, the body has an outer chamber which is filled with a granular material. The outer chamber can be ventilated or evacuated and can thus be subjected to a negative pressure. If the inner chamber is inflated and the outer chamber evacuated, a body with high rigidity results.

The object on which the invention is based is to propose a piece of furniture that can be used as flexibly as possible, which is as light as possible and at the same time offers good comfort.

The object is achieved by the features of the independent patent claims. Advantageous embodiments of the invention are specified in the subclaims.

According to a first aspect, the invention is characterized by an item of furniture with a first inflatable and / or evacuable, plate-shaped volume element and at least one non-inflatable support element. The first volume element is formed from a first flexible cover layer and a second flexible cover layer and an intermediate structure arranged between them. The intermediate structure is designed to mechanically couple the first cover layer to the second cover layer in such a way that, in an inflated and / or evacuated state, the first cover layer is at a predetermined distance from the second cover layer. In this case, the at least one support element can be mechanically coupled and decoupled from the first volume element without tools and is arranged in relation to the first volume element so that it can be used as a at least one standing surface of the piece of furniture is used.

Such a piece of furniture has the advantage that it is particularly light and, thanks to the individual components, particularly modular and thus versatile. The use of a volume element as a replacement for, for example, conventional upholstered seating or lying surfaces or non-upholstered storage surfaces made of wood offers comparable comfort with maximum flexibility at the same time. The piece of furniture can be designed as a lounger, sofa, armchair, stool, chair, shelf, table, etc.

Since the volume element is designed as such in the form of a plate, it thus has a length and a width which is greater than a thickness. Such a plate-shaped volume element can, however, in addition to being used as a component of the piece of furniture, in principle also be used for other purposes and thus very versatile. It is therefore multifunctional and can therefore be used in a particularly resource-saving manner, since one and the same volume element can be used for a wide variety of applications. The same can also apply to the at least one support element. If this is designed accordingly, it can also be used in another function in addition to the support function.

In order to use the first volume element as part of the piece of furniture, it must be brought into the inflated and / or evacuated state. The first volume element can be at least partially inflatable, for example with air, in order to assume a usable state. In order to assume a relaxed state, the inflated part of the volume element must be deflated. In addition, the volume element can also be partially evacuated in order to assume its usable state by applying a negative pressure. In order to assume a relaxed state, the evacuated part of the volume element must be ventilated. Of course, the volume element can also be either inflatable or evacuable in order to assume the usable state. When not in use, the first volume element can be folded very flexibly and to a relatively small pack size in a relaxed state or rolled up and thus easily transported or stowed or stored to save space so that the usable space can be increased.

The structure of the volume element with the first and second cover layer and the intermediate structure arranged in between enables a rigid and dimensionally stable element in the inflated and / or evacuated state, even under load. In order to allow an inflatable and / or evacuable space in the intermediate structure between the first and second cover layer, the side edges of the first volume element are sealed, for example by means of a closure tab. This end flap preferably runs in the area of the respective side edge between the first and second cover layer and is attached to these in a fluid-tight manner, e.g. glued, sewn and / or welded. The closure tab is preferably made of the same material and can have the same structure as the first or second cover layer.

The respective cover layer of the first volume element is preferably formed from a plastic material such as PVC, polycotton or nylon. The intermediate structure is preferably designed to mechanically couple the first and second cover layers in such a way that, in an inflated and / or evacuated state, the first cover layer is at a predetermined distance from the second cover layer over the extension of the intermediate structure. That is to say, in the inflated and / or evacuated state, the respective cover layer does not include any large bulges and / or large-area depressions, that is to say has an essentially smooth, continuously running surface. The distance between the cover layers over the extent of the intermediate structure can be constant. Alternatively, the distance between the first and second cover layer can also vary over the extension of the intermediate structure.

The intermediate layer extends essentially over the entire extent of the volume element. It can thus be ensured by means of the intermediate structure that the predetermined distance between the first and second Cover layer can be maintained in a wide overpressure and / or underpressure range over the extent of the volume element without bulges and / or depressions occurring. At the same time, a high compressive strength and flexural strength of the volume element can be achieved. The volume element can also be particularly heavily loaded and thus serve, for example, as a sitting, lying or storage surface.

The support element is not designed to be inflatable, but is mainly made of inflexible materials, e.g. wood, metal, etc., but can certainly be designed to be foldable, extendable, adjustable, slidable or otherwise variable. The support element can be designed as a solid component, but alternatively also be hollow and thus offer a stowage option which is accessible by means of a door, flap, drawer or otherwise or which is designed to be open on one or more sides. The at least one support element can also be designed, for example, in the form of a framework and consist of several struts. Of course, the piece of furniture can also comprise more than one support element.

The support element serves as a standing surface for the piece of furniture, i.e. it is at least partially arranged between the first volume element and a floor on which the piece of furniture stands. Arranged in a stationary interior space, such as a living room in an apartment or a house, as well as office space, the piece of furniture is preferably designed to be relocatable, i.e. the at least one support element can be moved.

The coupling between the first volume element and the support element is typically designed such that the first volume element is preferably fixed to the support element. The fixation is designed such that the first volume element in the inflated and / or evacuated state remains arranged in a predetermined contact area relative to the support element. This ensures that the piece of furniture is safe and reliable even when the first volume element is being used or is under load is usable. The coupling can, however, also be designed in such a way that the first volume element is still pivotably attached to the at least one support element.

In this context, "inflatable" means that the volume element can be filled with a gas, such as air, and thus at least partially pressurized in order to assume its usable state. “Evacuable”, on the other hand, means that the volume element can at least partially be subjected to a negative pressure in order to assume its usable state

In an advantageous embodiment of the first aspect, a contact area of the support element, in which the support element is in contact with the first volume element, follows a shape of the first volume element that is assigned to this contact area. The contact area of the support element preferably follows a shape of the first volume element over its entire width or its entire length. This has the advantage that the first volume element is optimally supported on the support element. Such a shaped contact area can also form or at least support the mechanical coupling between the first volume element and the support element.

In a further advantageous embodiment of the first aspect, the at least one support element is designed in such a way that the cover layer of the first volume element facing away from a base is oriented essentially horizontally during the coupling. Designed in this way, the cover layer of the first volume element facing away from the floor thus forms a comfortable seating or lying surface or a well-usable storage surface. If, for example, the distance between the first and second cover layer of the first volume element changes over its extent, the at least one support element is designed to compensate for this variation in thickness in such a way that the cover layer facing away from the floor is oriented essentially horizontally.

In a further advantageous embodiment of the first aspect, the first volume element is curved or kinked in the inflated and / or evacuated state. In this case, the support element in the usable state can for example be coupled to the first volume element in such a way that the first volume element is held in the curved or kinked state. Alternatively, the curvature or the kink can be brought about by a corresponding connection of the ends of the first volume element. In an advantageous embodiment, the first volume element in the curved or kinked state forms both a seating or lying surface and at the same time a backrest, such as a backrest.

In a further advantageous embodiment of the first aspect, the piece of furniture comprises a second inflatable and / or evacuable, plate-shaped volume element, which is formed from a first flexible cover layer and a second flexible cover layer and an intermediate structure arranged between them. The intermediate structure is designed to mechanically couple the first cover layer to the second cover layer in such a way that, in an inflated and / or evacuated state, the first cover layer is at a predetermined distance from the second cover layer. In a first use state, the first volume element rests on the at least one support element and is coupled to the second volume element in such a way that the second volume element with one of its cover layers faces the first volume element. The use of at least two volume elements for the piece of furniture expands its versatility and multifunctionality. Depending on the function of the respective volume element, it can particularly advantageously be acted upon by a suitable overpressure and / or underpressure. Both volume elements can thus have different positive or negative pressures depending on their function in the piece of furniture.

The second volume element is also designed in the form of a plate and thus has a length and a width which is greater than its thickness.

In this embodiment, the first volume element can for example be coupled to the second volume element in such a way that the second volume element is in contact with the first volume element with one of its cover layers. Alternatively, the second volume element can also be in contact with the first volume element with one of its edges, for example front or side edges, with the second volume element still facing the first volume element with one of its cover layers.

The coupling between the first and second volume element can for example take place by means of tensionable connecting elements. Alternatively or additionally, the coupling can take place by means of a backrest element which couples the first and second volume elements accordingly. The backrest element can be designed as a fixed component, e.g. non-inflatable, and in addition to the support element also assume a supporting function. It is also conceivable to design the backrest element in such a way that, in addition to the coupling function, it also serves as an armrest or backrest.

In a further advantageous embodiment of the first aspect, the second volume element in the first usage state is arranged essentially perpendicular to the first volume element. In this form, the piece of furniture can be designed as seating furniture, for example, the first volume element serving as a seat and the second volume element serving as a backrest. Alternatively or additionally, the second volume element can also support the first volume element in addition to the support element. As a result, the piece of furniture in this embodiment can be designed as a couch, stool, table, shelf, armchair, etc., for example.

In a further advantageous embodiment of the first aspect, the at least one support element is designed so that it can be pulled out or extended in a second use state. In this case, both the first and the second volume element can be coupled to the at least one extended or extended support element. This has the advantage that one piece of furniture with two Can use volume elements in the first usage state, for example, as seating furniture, but at the same time can convert them into a lying surface, in which both volume elements serve as a lying surface in the second usage state. But other possible uses are also conceivable. In this case, the at least one pull-out or extendable support element is designed in such a way that the respective cover layer of both volume elements facing away from the floor is oriented essentially horizontally.

In this embodiment of a piece of furniture with a first and a second volume element, the mechanical coupling between the first volume element and the at least one support element can in principle also be dispensed with. Thus it would also be possible to form a piece of furniture with a first and a second inflatable, plate-shaped volume element and at least one non-inflatable support element, wherein the respective volume element is formed from a first flexible cover layer and a second flexible cover layer and an intermediate structure arranged in between, wherein the respective intermediate structure is designed to mechanically couple the first cover layer to the second cover layer in such a way that in an inflated and / or evacuated state the first cover layer is at a predetermined distance from the second cover layer, the first volume element in a first use state on the at least supports a support element and the second volume element is arranged substantially perpendicular to the first volume element. In the case of the piece of furniture with two volume elements, it is also possible that the second volume element is coupled to the first such that the first volume element rests on the at least one support element in the first usage state and is coupled to the second volume element in such a way that the second volume element is also one of its cover layers is in contact with the first volume element. In a second use state, the at least one support element can be designed to be extendable or extendable, in which case both the first and the second volume element can be supported on the at least one extended or extended support element.

In a further advantageous embodiment of the first aspect, in the intermediate structure of the respective volume element, a plurality of stabilizing threads of the same length run between the assigned first and second cover layers, at least in regions. Such a design corresponds to a so-called drop stitch structure with a large number of stabilizing threads between the first and second cover layer. One or more chambers can be assigned to the intermediate structure. Such a structure of the volume element offers high dimensional and bending stability and at the same time has high tear resistance. The volume element with a drop-stitch structure is preferably subjected to excess pressure. With a drop-stitch structure, the predetermined shape of the volume element can be retained even with a very high excess pressure. If several chambers are assigned to the intermediate structure and these are each designed as a drop stitch structure, the volume element can be adapted to its desired function for the piece of furniture by applying differently predetermined excess pressures across the chambers. For example, the volume element or individual chambers with the drop-stitch structure can each be inflated to an overpressure range between 0.3 and 2 bar.

The stabilizing threads form the mechanical coupling between the first and second cover layer. The length of the stabilizing threads essentially determines the thickness of the volume element over its extension. The thickness of the volume element is preferably approximately 10 cm. But other thicknesses of, for example, 15 or 20 cm are also possible. In this configuration, the intermediate structure is preferably designed to mechanically couple the first and second cover layers in such a way that, in the inflated state, the first and second cover layers run essentially parallel over the extent of the intermediate structure.

If several volume elements are used for the piece of furniture, one or more volume elements can comprise a drop-stitch structure as an intermediate structure.

In a further advantageous embodiment of the first aspect, a further inflatable wear layer is assigned to at least one cover layer of the first volume element. This inflatable wear layer can be arranged on the associated cover layer or integrated into it. This wear layer is mainly used for comfort. When inflated, this wear layer can provide a soft surface. The overpressure with which the wear layer is applied typically differs from the overpressure with which the intermediate structure of the first volume element is applied. In addition, this usage layer can have a breathable surface or padding. For example, the inflatable wear layer can be assigned to the cover layer of the first volume element which faces away from the floor. Alternatively or additionally, the inflatable wear layer can be assigned to the cover layer of the second volume element which is in contact with the first volume element.

In a further advantageous embodiment of the first aspect, at least one volume element of the piece of furniture has at least one stabilization element of predetermined length and width, which is arranged on or in the first or second assigned cover layer. The at least one stabilization element runs in the longitudinal and / or transverse direction and is designed to bring about additional stiffening of the volume element in the usable state. The at least one stabilization element is designed to be flexible, for example, and has a high modulus of elasticity and a high tensile strength and thus effects additional stiffening of the volume element. For example, the stabilizing element is designed as a fiber band or fiber strip which comprises fibers that have a high modulus of elasticity in the direction of the fibers and are particularly tensile strength. A width of the fiber band or fiber strip can, for example, be between a few millimeters and a few centimeters and extend in the transverse and / or longitudinal direction. Alternatively, the stabilizing element can also be designed as a fiber layer over a large area and be arranged on or in at least one of the cover layers. For example, the fiber tape, the fiber strip or the fiber layer can comprise synthetic fibers such as aramid, polyethylene, CFRP / GFRP fibers, or natural fibers such as cotton or hemp fibers. If, for example, the volume element is loaded on one side, the stabilization element can be arranged or integrated on the side of the volume element opposite the load on or in the assigned cover layer. As a result, the stabilization element counteracts the load due to the high modulus of elasticity and tensile strength. A deflection of the volume element resulting from the load can thereby be reduced. The stabilizing element can for example be glued onto or in the assigned cover layer. If the respective volume element is subjected to a lower overpressure and / or underpressure than is actually required for the additional stiffening, the volume element can also be correspondingly curved or kinked with at least one stabilizing element.

According to a second aspect, the invention is characterized by the use of the piece of furniture according to the first aspect in or on a stationary living space for a first period and the use of the at least one volume element and / or the at least one support element of the piece of furniture in or on or for a mobile living space for a second period. This configuration has the advantage that the piece of furniture can be used multifunctionally. For example, the piece of furniture can be used in an apartment or house, for example as a seat. In addition, the volume element or elements and / or the at least one support element can also be used in a mobile living space. The mobile living space can be designed, for example, in a vehicle or as a vehicle that can be used at least temporarily, such as a mobile home, caravan, camping vehicle, etc. For example, the at least one volume element and / or the At least one support element of the piece of furniture serves as a bed or seat pad in the mobile living space, while the rest of the time as a first period in or on the stationary living space, such as an apartment or a house, as a piece of furniture is usable. Because of the basically robust design of the at least one volume element, the piece of furniture can also be used outside of the stationary or mobile living space, for example as a piece of garden furniture.

In the figures, the same reference symbols are used for the same or at least similar elements, components or aspects. It should be noted that the embodiments described below only represent a limited selection of possible embodiment variants of the invention. In particular, it is possible to combine the features of individual embodiments with one another in a suitable manner, so that for the person skilled in the art with the embodiment variants explicitly shown here, a large number of different embodiments are to be seen as obviously disclosed.

In Fig. 1 is an inflatable and / or evacuable plate-shaped volume element 2 shown in an inflated and / or evacuated state. The inflated and / or evacuated state of the volume element 2 represents a usable state. The volume element 2 has a first and a second side edge 8a, 8b. In addition to the first and second side edges 8a, 8b, the volume element 2 has corresponding first and second end edges 9a, 9b on the two end faces. The side edges and front edges can also be referred to as edges.

The volume element 2 also has a first and a second cover layer 6a, 6b. An intermediate structure 10 is arranged in between. At the edges 8a, 8b, 9a, 9b, an end tab can run (not shown). This connects the first cover layer 6a to the second cover layer 6b at the respective edge and is connected to the respective cover layer 6a, 6b in a fluid-tight manner, e.g. glued, sewn and / or welded. At or in the area of the corners of the volume element 2, the end tabs are connected to one another in a fluid-tight manner. Alternatively, the end flap can be designed as an endless material and be connected to the first and second cover layers 6a, 6b along all edges 8a, 8b, 9a, 9b. By means of the closing tab and the first and second cover layers 6a, 6b, a fluid-tight space can thus be created in the volume element 2, which can be subjected to an overpressure and / or underpressure. The intermediate structure 10 of the volume element 2 is assigned to this fluid-tight space.

The first and second cover layers 6a, 6b are designed to be flexible and each have at least one material layer. Alternatively, the respective cover layer can also have several layers. For example, the respective material layer of the cover layer can be made of a plastic material, for example PVC, nylon, etc. The cover layer can also be made at least partially from recycled plastic. The end tab can be made from the same material as the first or second cover layer 6a, 6b. The respective end flap can, however, differ from the first and second cover layers 6a, 6b in terms of surface texture and properties.

In the inflated and / or evacuated state, the first and second cover layers 6a, 6b of the volume element 2 can be made very hard. If this is not desired, the first and / or second cover layer 6a, 6b can for example be provided with additional padding, for example foam or a breathable coating, for example a cotton padding or coating. Alternatively or additionally, a further inflatable wear layer 7 can be assigned to the respective cover layer, which provides a softer surface in the inflated state (see FIG Fig. 5 ).

The intermediate structure 10 can have a multiplicity of stabilizing threads in regions, which mechanically couple the first cover layer 6a to the second cover layer 6b (not shown). These stabilizing threads are preferably assigned to the intermediate structure 10 and are sewn or glued with their respective ends in the first and second cover layers 6a, 6b. The stabilizing threads are made of nylon, for example. In this embodiment with stabilizing threads, the structure of the intermediate structure 10 corresponds to a so-called drop-stitch structure, which as a rule gains its strength when the fluid-tight space of the intermediate structure 10 is filled with a gas, such as air, and with a sufficient overpressure, such as 0.5 to 2 bar, is applied.

Typically, the stabilizing threads have the same lengths and thereby determine the distance between the first and second cover layers 6a, 6b and thus the thickness of the volume element 2 in the direction of the thickness. For example, the volume element 2 can have a thickness of approximately 10 cm. The stabilizing threads typically run in the inflated state on the shortest path between the first and second cover layers 6a, 6b, ie they have a perpendicular course relative to the cover layers. Alternatively or additionally, however, the stabilizing threads in the inflated state can also assume a different angle relative to the cover layers, for example an X-shaped course between the first and second cover layers 6a, 6b.

If the intermediate structure 10 is designed as a drop-stitch structure, the first and second cover layers 6a, 6b are typically mechanically coupled in such a way that, in the inflated state, the first and second cover layers 6a, 6b run essentially parallel over the extent of the intermediate structure 10.

A plurality of chambers can be assigned to the intermediate structure 10, each of which is fluidically separated from one another. Each chamber is assigned a valve via which the chamber can be subjected to either an overpressure or a negative pressure. These chambers with the respective chamber walls at least partially form a mechanical coupling between the first and second cover layer 6a, 6b. The respective chamber of the intermediate structure 14 can be designed as a drop-stitch structure and have a multiplicity of stabilizing threads between the first and second cover layers 6a, 6b. The respective drop stitch chamber can thus be subjected to an associated overpressure.

Alternatively, the intermediate structure 10 can also be assigned a plurality of fluidically separate chambers, some of which are filled with a granulate. The chambers filled with granules can then be subjected to a negative pressure. A material can be used as the granulate, which in an evacuated state causes a high level of friction between the granulate particles and thus assumes a very rigid and pressure-stable state. Further requirements for such a granulate can also be low weight, insulation properties, low costs, availability, environmental compatibility, etc. For example, a plastic or biogranulate or other materials can be used.

In contrast, the chambers not filled with granules are preferably subjected to an overpressure. Through the combination of chambers that can be acted upon by granules and a negative pressure with chambers that can be acted upon by an overpressure, a high degree of rigidity, in particular pressure and flexural rigidity, of the intermediate structure 10 and thus of the volume element 2 can be achieved. In this case, the granulate in the at least one second chamber in the evacuated state also represents the mechanical coupling between the first and second cover layer. The chambers which can be evacuated and are filled with granulate are preferably arranged in the vicinity of the cover layers and the inflatable chambers in the interior of the volume element.

If the intermediate structure 10 is formed from the combination of chambers that can be acted upon by granules and a negative pressure with chambers that can be acted upon by an overpressure, the first and second cover layers 6a, 6b are preferably mechanically coupled in such a way that the first and the first and the second cover layer 6a, 6b run essentially parallel over the extent of the intermediate structure 10. Alternatively, the mechanical coupling between the first and second cover layers 6a, 6b can be formed by means of the intermediate layer 10 such that the distance between the first and second cover layers 6a, 6b varies.

Furthermore, in Fig. 1 indicated that the first cover layer 6a is assigned several longitudinal stiffening elements 3a and several transverse stiffening elements 3b. These stiffening elements 3a, 3b can alternatively or additionally also be assigned to the second cover layer 6b (not shown). Both the longitudinal stiffening elements 3a and the transverse stiffening elements 3b can each be referred to as stabilizing elements which run in the plane of the respective cover layer. For example, the respective stiffening element 3a, 3b is designed as a flexible fiber band with a high modulus of elasticity and a high tensile strength, for example as an aramid fiber band. The volume element 2 can either have longitudinal stiffening elements 3a or transverse stiffening elements 3b arranged or integrated on or in the first or second cover layer 6a, 6b. Alternatively, as in Fig. 1 shown that volume element 2 have both the longitudinal 3a and 3b transverse stiffening elements. The longitudinal and transverse stiffening elements 3b can be assigned to a cover layer or in any conceivable combination distribute the first and second cover layers 6a, 6b. Basically. it is also possible for the stabilizing elements to run obliquely or diagonally in the plane of the assigned cover layer. A large-area design of the stabilizing element as a fiber layer is also possible, which is arranged on or in at least one of the cover layers.

These stabilizing elements can be used both for volume elements with an intermediate structure designed as a drop-stitch structure and for volume elements with an intermediate structure that has a combination of chambers that can be acted upon with granules and a negative pressure and chambers that can be acted upon with an overpressure.

In Fig. 2 a piece of furniture 1 is shown. This piece of furniture 1 comprises a first inflatable and / or evacuable volume element 2a and a support element 4. The first volume element 2a is preferably a volume element 2 in accordance with FIG Fig. 1 formed and has its structure, properties and features. While the first volume element 2a can be inflated and / or evacuated, the support element 4 is designed as a solid, non-inflatable or non-evacuable element. It is preferably made of a non-flexible material, such as wood, metal, plastic, etc., but can certainly have a predetermined variability, such as height and / or length and / or width adjustment. The support element 4 is arranged between the first volume element 2a and a floor on which the piece of furniture 1 stands. The support element 4 thus serves as a standing surface for the piece of furniture 1 on the floor. The piece of furniture 1 can according to the Fig. 1 be designed as a table. The support element 4 is coupled to the first volume element 2a. The coupling can take place by means of tensionable connecting elements, for example belts, turnbuckles, rubber belts, etc., which are fastened both to the support element 4 and to the first volume element 2a. In order to enable particularly simple handling, the coupling of the first volume element 2a with the at least one support element 4 can be coupled and decoupled without tools. The coupling between the first volume element 2a and the at least a support element 4 is designed such that both components are fixed relative to one another. For fastening to the first volume element 2 a, it can have one or more fastening elements, for example D-ring patches, which are arranged on the cover layer facing the support element 4. Alternatively or additionally, one or more fastening elements can also be fastened to the end straps. The D-ring patches as fastening elements can be glued or sewn. As an alternative to the D-ring patches, inserts can also be integrated in the assigned cover layer and / or end flap, which make it possible to screw in connecting elements. Of course, the piece of furniture 1 in Fig. 2 several support elements can also be assigned.

The first volume element 2a can, for example, have a length of 2 m, a width of 0.7 m and a thickness of 0.1 m. The length and width of the at least one support element 4 corresponds to the size of the first volume element 2a in such a way that the first volume element 2a is mounted on it in a stable and secure manner and can perform the predetermined function of the piece of furniture 1. The support element 4 is preferably designed such that the cover layer facing away from the floor is aligned horizontally.

The at least one valve of the first volume element 2a is arranged, for example, on the cover layer which faces the at least one support element 4, so that there is an essentially flat surface on the opposite cover layer in the inflated state.

If two pieces of furniture 1 designed as a table are placed one on top of the other, a shelf with several storage areas is obtained, which are realized by the respective volume element.

Alternatively, if the volume element designed as a table surface is used as a lying surface and a further lying surface is placed under the table, for example another volume element, a bunk bed can be created in a simple manner.

The piece of furniture can also have at least one support element with a predetermined height, so that the first volume element can be at least partially suspended from this support element underneath, for example by means of one or more straps, rods, ropes, etc., without the first volume element being affected Touches the ground. In this case, the fastening elements suitable for hanging form the mechanical coupling between the first volume element and the at least one support element. Furthermore, in this embodiment, too, the at least one support element forms at least one standing surface of the piece of furniture.

In Fig. 3 Another embodiment of a piece of furniture 1 is shown. In addition to the first volume element 2a, this also comprises a second, inflatable and / or evacuable plate-shaped volume element 2b. The piece of furniture 1 is designed here, for example, as a seat, such as an armchair or sofa.

The second volume element 2b is designed analogously to the first volume element 2a and, as such, can be inflated and / or evacuated and has an analogous structure. The second volume element 2b can also include all additional features such as inflatable wear layer, stabilization elements 3a, 3b, etc., as previously for the in Fig. 1 volume element 2 described have.

The piece of furniture 1 further comprises two support elements 4a, 4b. The first volume element 2a is coupled to these support elements 4a, 4b in such a way that the cover layer facing away from the floor is oriented essentially horizontally. As a result, the first volume element 2a can form a seating, lying or storage surface. The two support elements 4a, 4b are arranged between the first volume element 2a and the floor on which the piece of furniture 1 stands. Both support elements 4a, 4b thus serve as a respective standing surface for the piece of furniture 1, as in FIG Fig. 3 shown, at least one support element 4a can be designed to support the first volume element 2a and at the same time also a backrest, for example armrests. In a further embodiment of the at least one support element, it can also be designed as a backrest. The first and / or second volume element can be suspended from this, so that the at least one support element continues to form at least one standing surface of the piece of furniture.

The support elements 4a, 4b can have a height, taking into account the thickness of the first volume element 2a, so that the cover layer of the first volume element 2a facing away from the floor has a comfortable sitting or lying height relative to the floor. The respective support element 4a, 4b can be made solid and / or in one piece or alternatively have additional functions, such as a cavity that can also be used as storage space. An open and / or frame-like design of the respective support element 4a, 4b is also possible, so that access is possible even without folding the first and / or second volume element 2a, 2b. The two support elements 4a, 4b are spaced apart from one another in such a way that the first volume element 2a can be used as a seating, lying or storage area. In principle, the piece of furniture 1 can also have more than two support elements, for example a third, which is arranged between the first and second support elements 4a, 4b. The first volume element 2a can also be mounted on a single support element which is designed to be correspondingly wide and deep. In principle, one or more support elements can also be assigned additional functions, such as electrical or electronic functions such as loudspeaker or lighting functions.

The first cover layer 6a 'of the second volume element 2b faces the first volume element 2a in such a way that it is in contact with the first volume element 2a. Both volume elements 2a, 2b are arranged approximately perpendicular to one another. The second volume element 2b is in contact with one of its side edges with the floor, the side edges being aligned in the longitudinal direction of the respective volume element. Both volume elements 2a, 2b are approximately the same length. The thickness and also the width of both volume elements 2a, 2b can be the same or also each different. The contact area between the first and second volume elements 2a, 2b is shown in FIG Fig. 3 formed approximately at half the width of the second volume element 2b. The area above the contact area can thus serve as a backrest, in particular a backrest.

The first volume element 2a is coupled to the second volume element 2b without tools. This can be done using tensionable connecting elements 12, e.g. by means of belts, turnbuckles, rubber elements, etc. In addition, the first volume element 2a can be coupled to the two support elements 4a, 4b without tools, for example also by means of tensionable connecting elements. Furthermore, the second volume element 2b can also be coupled to one or more support elements, for example below the contact area between the two volume elements 2a, 2b. The coupling between the first and second volume elements 2a, 2b can also take place by means of an additional backrest element (not shown) which is formed separately from the support elements 4a, 4b. This backrest element can also perform an additional support and / or backrest function, e.g. as an armrest.

The at least one support element 4a, 4b can be designed to be extendable. For example shows Fig. 4 an embodiment in which the two support elements 4a, 4b are extended in such a way that these two form both a support for the first and for the second volume element 2a, 2b in such a way that both volume elements 2a, 2b are aligned approximately horizontally.

In Fig. 3 the piece of furniture 1 is shown in a first state of use, namely, for example, as a seat with a backrest, while the same or a similar piece of furniture 1 in Fig. 4 is shown in a second use state, namely as a couch or bed. Here, too, both volume elements 2a, 2b can be coupled to one another without tools by means of one or more tensionable connecting elements 12. In addition, both volume elements 2a, 2b be mechanically coupled to the two support elements. The coupling is preferably designed without tools.

In Fig. 5 is a to run in Fig. 3 Similar piece of furniture 1 shown in a side view. The second volume element 2b is arranged essentially perpendicular to the first volume element 2a, while the first volume element 2a is supported on the support elements 4a, 4b. In Fig. 5 the first volume element 2a is shown slightly spaced from the support element 2b for explanation, to show that a contact side of the support element 2b facing the first volume element 2a follows a shape of the first volume element 2a over its entire width in the inflated state in this area. A coupling and fixing of the first volume element 2a to the respective support element can thereby be formed or supported. In a coupled state, the first volume element 2a and the in Fig. 5 shown support element 4b of course not spaced, but preferably in direct contact.

As already mentioned, the cover layer of the first volume element 2a, which faces away from the floor, can have an additional inflatable wear layer 7. This can improve sitting or lying comfort. Alternatively or in addition, the second volume element 2b can also have such an inflatable wear layer 7 (not shown). Instead of this wear layer 7, other padding can also be provided, such as foam padding. Furthermore, a cushion clip 11 can also be assigned to the second volume element, which is slipped over a side edge facing away from the floor and which comprises an additional cushion. This can additionally improve the backrest comfort and / or serve as a headrest.

In Fig. 6 a piece of furniture 1 designed as a seat or as a bed with a first volume element 2a is shown in the usable state. It is coupled to the support element 4a in such a way that it assumes a curved or kinked state in the usable state. In this version, both one area of the first volume element 2a serves as a seat and a second, different area as a backrest. The support element 4a is preferably designed to be foldable and / or pluggable, so that the piece of furniture according to FIG Fig. 6 particularly easy to assemble and dismantle and easy to transport.

In Fig. 7 a living space 16 is shown, which is designed, for example, as a vehicle interior or as a living space that can be coupled or decoupled from a vehicle 14. The living space 16 can also be referred to as a mobile living space. In the living space 16, a piece of furniture 1 is shown which has the first volume element 2a and two support elements 4a, 4b. For example, the piece of furniture 1 is designed as a bench or bed in the vehicle 14. Above the piece of furniture 1, the second volume element 2b is shown hanging at least partially from a ceiling of the living room 16, which is designed in this form, for example, as a further bed. The piece of furniture 1 and the second volume element 2b designed as a further bed form in this embodiment, for example, a bunk bed over two floors.

Looking at the embodiments of the piece of furniture 1 in FIG Figures 3 to 6 , which are typically used in a stationary living space, such as an apartment or a house, the modularity and flexibility of the piece of furniture 1 also enables use in the vehicle 14. The piece of furniture 1 can be used as a whole as in Figures 3 to 6 can also be used in vehicle 14. The use in the mobile living space is particularly advantageous when the at least one support element has a height that is equal to or slightly greater than a wheel arch, so that the volume element can be supported on the at least one support element without the wheel arch interfering.

Alternatively, the components of the piece of furniture 1 can also be put together to form another, new piece of furniture in the vehicle, for example as a bunk bed as in Fig. 7 shown. Ie from the seating in the stationary Living space becomes a bed in the mobile living space 14. The support elements 4a, 4b, which serve as a support for at least one volume element in the stationary living space, can be stacked on top of each other in the mobile living space (not shown) and thus serve as a shelf through which Additional storage space is created or in which, for example, boxes, such as euro boxes, can be pushed. Not all components of the piece of furniture 1 have to be used in the vehicle 14, but only individual components can be used.

Of course, it is also possible to use the piece of furniture 1 or components thereof in or on the stationary living space for other functions. This multifunctionality enables a particularly resource-saving and also sustainable use of the piece of furniture 1 and its components to be achieved.

The vehicle 14 is preferably designed as a land vehicle, for example a station wagon, van, bus, box truck, mobile home or trailer, for example a caravan.
