Description

[0001] Piece of furniture and method for producing a piece of furniture

[0002] The invention relates to a piece of furniture according to the preamble of claim 1 and to a method for producing a piece of furniture according to the preamble of claim 10.

[0003] It is known in the art to manufacture furniture, and especially beds, from various materials, but typically from wood. Wooden furniture construction has a long tradition, based on its comparatively low weight, good processability, and high stability of the material. However, it is also known to manufacture beds, for example, from metal. Furthermore, it is known to incorporate inlays made of tiles, artificial or natural stone slabs, especially for tables and benches.

[0004] In this context, DE 591 903 C1 describes the use of plywood hollow bodies for the manufacture of furniture and other objects. The furniture is made entirely or partially from seamlessly wound or cup-shaped drawn plywood hollow bodies, which can take on various shapes. DE 591 903 C1 thus enables the production of lightweight and stable furniture with minimal wall thickness without the need for additional scaffolding or frames, which is particularly suitable for use in ships and aircraft. The hollow bodies can be made from various wood species and covered with special veneers to enhance aesthetics and functionality.

[0005] DE 29 917 733 U1 discloses a lightweight, easy-to-assemble and disassemble bed that also requires little space to transport. Design features such as side elements with dovetail-shaped end shapes, segmental-arch-like notches and recesses that interlock, as well as the use of thin materials, create a lightweight yet stable bed. DE 19 911 189 A1 describes a process for manufacturing lightweight furniture that is particularly suitable for outdoor use. For this purpose, a custom-shaped core, usually made of rigid foam, is first covered with fabric mats. These mats serve as a support for tiles, which are attached with a special adhesive and grouted after the adhesive has hardened. Additional measures such as a moisture barrier between the core and the tiles and the option of pretreating the core with filler improve moisture protection.

[0006] A bed made of solid marble is also known under the product name “FS400” from the manufacturer “Felix Schwake”.

[0007] However, these familiar pieces of furniture are disadvantageous in that they cannot combine the elegant appearance of a piece of solid stone with the low production costs, ease of transport, and ease of assembly of lightweight furniture. This is particularly disadvantageous for use in hotels, which want to offer their guests elegant furniture that must also be economically viable.

[0008] It is an object of the present invention to propose an improved piece of furniture.

[0009] This object is achieved according to the invention by the piece of furniture according to claim 1. Advantageous embodiments and further developments of the invention emerge from the dependent claims.

[0010] The invention relates to a piece of furniture comprising an inner structure, an intermediate structure and an outer structure, wherein the inner structure represents a supporting frame and defines an outer shape of the piece of furniture, wherein the inner structure is designed as a lightweight structure, wherein the intermediate structure enables the outer structure to be arranged on the inner structure and wherein the outer structure consists of tiles, porcelain stoneware and / or natural stone slabs. According to the invention, the piece of furniture is designed as a bed and that the inner structure (40) consists of rigid foam, Styrodur, aerated concrete, metallic U-profiles and / or wood and the intermediate structure (30) comprises a fabric layer (32) and / or a nonwoven layer and / or plasterboard and / or OSB boards. Thus, a piece of furniture consisting of several structural layers is provided which is designed as a bed.This bed features a unique construction method that includes an internal structure, an intermediate structure, and an external structure. The combination of these three structures makes it possible to create a bed that combines low manufacturing costs, low weight, and easy assembly with a high-quality aesthetic. Particular attention is also paid to the use of high-quality materials such as tiles, porcelain stoneware, and natural stone slabs for the external structure and thus for the exterior appearance. The natural stone slabs can be marble or granite, for example.

[0011] Since the piece of furniture according to the invention is designed as a bed, it differs in various respects from known pieces of furniture that also have a multi-layered structural design. Firstly, these known pieces of furniture are not designed as beds, but as tables or seating furniture. Furthermore, the known pieces of furniture use a tile layer in their outer structure to achieve weather resistance, which, however, is not important for the piece of furniture according to the invention, since beds are used exclusively indoors. Accordingly, the known pieces of furniture use weather-resistant tiles, which, however, generally do not make a visually high-quality impression as porcelain stoneware, natural stone slabs, or tiles for indoor use. Thus, the weather-resistant tiles for outdoor use of the known pieces of furniture appear unsuitable for the piece of furniture according to the invention.

[0012] The bed's internal structure forms the supporting frame or framework and is equally crucial for its stability and defines its external shape. It is designed as a lightweight structure, meaning it is both robust and weight-efficient, enabling easy assembly and maintaining the bed's mobility, allowing it to be moved around the room, for example, for cleaning purposes.

[0013] The intermediate structure and the outer structure are then each arranged on the inner structure and cover it.

[0014] The intermediate structure serves as a link between the interior and exterior structures. Its primary function is to enable a reliable and stable arrangement of the exterior structure on the interior structure. The intermediate structure thus ensures that the exterior materials can be firmly and securely attached.

[0015] Depending on the specific design, the intermediate structure can also provide additional functionalities, such as serving as a moisture barrier or compensating for different thermal expansions of the internal structure and the external structure.

[0016] Finally, the outer structure forms the visible surface of the bed and is made of high-quality materials such as tiles, porcelain stoneware and natural stone slabs.

[0017] This selection of materials not only offers a rich palette of design options to satisfy diverse style preferences, but also ensures durability and resistance to wear and tear. The use of these materials in the outer structure gives the bed a sophisticated and high-quality feel.

[0018] The invention thus proposes a bed that combines low manufacturing costs, design flexibility, durability, and high-quality exterior materials in a lightweight construction. In particular, due to the bed's invisible lightweight construction, it can be installed in almost any room of a building, such as a hotel, without the need for special reinforcement of the suspended ceilings, even if several of the beds according to the invention are installed in several rooms on one floor.

[0019] However, a visually similar bed made of solid material, such as marble, could not be placed in any room without further measures.

[0020] Because the bed's surface is made of tiles, porcelain stoneware, or natural stone slabs, the bed itself is also hypoallergenic. Combined with appropriate bedding, the bed is therefore particularly suitable for allergy sufferers.

[0021] In addition, the bed can be manufactured entirely without wood. This eliminates the need to cut down forests or trees to manufacture the bed. This makes the bed an extremely sustainable product, especially given its longevity.

[0022] According to a preferred embodiment of the invention, the piece of furniture is designed as a double bed. This makes the bed particularly suitable for couples or people who prefer the extra space when sleeping.

[0023] Even in hotels, a large number of bookable rooms are rented as double rooms, which accordingly require a double bed.

[0024] The interior structure of the double bed is correspondingly larger and reinforced where necessary to meet the increased requirements in terms of weight and stability. Despite the larger dimensions, the lightweight construction is retained to keep the bed easy to handle and assemble.

[0025] The interior structure is intended to be made of rigid foam, Styrodur, concrete, aerated concrete, metallic U-profiles and / or wood.

[0026] Each of these materials brings specific advantages in terms of the bed's construction and functionality:

[0027] Rigid foam or Styrodur, for example, offers high strength and low weight, making them a good choice for the lightweight interior structure. Their use also reduces the bed's heat capacity, which can contribute to a more comfortable sleeping environment.

[0028] Concrete and aerated concrete are particularly robust and durable. Their use in the interior structure of a bed ensures very high stability. Aerated concrete also has the advantage of being lighter than conventional concrete, which makes handling and assembly easier. Furthermore, concrete and aerated concrete are fireproof materials. If concrete or aerated concrete is used for the interior structure, these materials advantageously form a skeletal structure rather than a solid structure, in order to maintain the lightweight construction of the interior structure.

[0029] Before being used for the interior structure, the concrete is preferably poured into specially designed form elements, which then represent the individual elements of the interior structure. Particularly advantageously, the concrete or the individual elements can be reinforced with steel, which further improves stability.

[0030] Metal U-profiles offer high strength with relatively low weight, enabling precise construction of the internal structure. Wood combines high stability with easy processing and comparatively low weight.

[0031] The ability to manufacture the interior structure of the piece of furniture from a variety of materials allows for adaptability to different load, weight and manufacturing requirements.

[0032] According to a further preferred embodiment of the invention, it is provided that the intermediate structure comprises a filler layer.

[0033] As described, the intermediate structure has the task of ensuring a safe and reliable connection between the outer structure and the inner structure.

[0034] Due to their material properties, a fabric or fleece layer offers an excellent opportunity to compensate for material stresses that occur between the outer and inner structures, particularly due to differences in thermal expansion. The use of a fabric or fleece layer also inhibits the transmission of structure-borne sound in the bed.

[0035] The fabric layer or fleece layer can, for example, be glued to the inner structure either at specific points or across the entire surface. Furthermore, the fabric layer or fleece layer can be filled, i.e., have an additional layer of filler to facilitate the arrangement of the outer structure on the fabric layer or fleece layer.

[0036] To enable nonwoven layer.

[0037] Drywall is known for its ease of processing and good sound insulation. Furthermore, drywall provides a solid and smooth surface for attaching the exterior structure.

[0038] OSB (Oriented Strand Board) boards are characterized by their high strength and durability, low weight, and easy processing.

[0039] The use of a filler layer allows for an extremely smooth and adaptable surface for the exterior structure. It is well-suited for creating a suitable surface texture for the application of the chosen exterior structure. The filler layer is preferably applied to the interior structure in addition to one of the previously mentioned layers. Depending on the filler used, the filler layer can also block moisture penetration and improve the bed's resistance to liquids, thus increasing its durability.

[0040] According to a further preferred embodiment of the invention, it is provided that the intermediate structure comprises electrical heating wires and / or hydraulic temperature control lines.

[0041] This makes it possible to control the temperature of the bed, especially in cold ambient temperatures by heating it via the heating wires or the hydraulic temperature control lines, or to cool it via the hydraulic temperature control lines in warm ambient temperatures.

[0042] Embedding electrical heating wires into the intermediate structure enables fast and efficient heat generation. The heating wires are preferably evenly integrated into the intermediate structure to ensure even heat distribution. They can advantageously be controlled via adjustable thermostats to enable precise temperature regulation.

[0043] In addition to the aforementioned electric heating wires, the inclusion of hydraulic temperature control lines offers a versatile solution for temperature regulation. Hydraulic temperature control lines can be used to both heat and cool the bed by circulating water or another fluid through them, adjusting the temperature to the user's needs. This type of temperature control is particularly suitable for countries with fluctuating climatic conditions, as it provides year-round comfort.

[0044] The temperature control systems significantly increase the comfort of the bed and help to create an optimal sleeping environment tailored to the individual needs of the user.

[0045] According to a further preferred embodiment of the invention, it is provided that the outer structure has metallic rails on its edges and / or is mitred.

[0046] As described, the bed has a high-quality appearance in its outer structure.

[0047] It is therefore advantageous to attach metallic rails, preferably made of chrome or stainless steel, to the edges, which not only provide an aesthetic enhancement but also help to protect the edges and the joints against the penetration of moisture.

[0048] Alternatively, the outer structure can be mitered at the connecting edges, allowing for a precise and visually appealing connection of the edges. This also underscores the high-quality appearance of the bed.

[0049] According to a further preferred embodiment of the invention, it is provided that the bed has a display that can be retracted into a foot part of the bed.

[0050] The display can advantageously be designed as a television.

[0051] This functionality further enhances the comfort of the bed by allowing multimedia content to be consumed directly from the bed. The integration of the display into the bed's design seamlessly integrates with the overall aesthetic while providing a modern convenience.

[0052] According to a further preferred embodiment of the invention, it is provided that the bed comprises a rear wall arranged behind a headboard of the bed with an identical external structure as the bed.

[0053] The back wall can also have an inner structure, an intermediate structure, and an outer structure. In this case, the back wall does not need to be permanently attached to the room wall. Alternatively, the outer structure can be attached directly to a wall at the head of the bed, thereby firmly connecting it to the wall and defining a location for the bed.

[0054] The back wall not only expands the aesthetic concept of the bed and creates a harmonious overall picture, but it also creates a surface on which the bed can be placed flush against the wall.

[0055] According to a particularly preferred embodiment of the invention, it is provided that at least one decorative fountain is arranged in the rear wall.

[0056] The decorative fountain lends a calming atmosphere to a room containing the bed according to the invention. It also creates a relaxing soundscape and can assist in falling asleep, making this embodiment particularly suitable for users with poor sleep or difficulty falling asleep. According to a further preferred embodiment of the invention, the bed includes at least one bedside table firmly attached to the bed, with an identical external structure to the bed.

[0057] This uniform design ensures a coherent appearance and further underscores the high-quality feel of the bed. At least one bedside table can be directly connected to the bed itself or to the back wall.

[0058] According to a further preferred embodiment of the invention, it is provided that the bed comprises a slatted frame, wherein the outer structure forms a tray so that the slatted frame can be placed on the tray or wherein the tray has fastening devices on its inside for receiving the slatted frame and wherein the tray also has at least one ventilation passage.

[0059] The outer structure of the bed therefore forms a tub, which means that the outer structure advantageously forms four walls, one at the head and foot of the bed and one on each side.

[0060] A slatted frame can either be placed directly on the tub or the tub has fastening devices on its inside, such as hooks or special support surfaces, onto which the slatted frame can be placed.

[0061] The slatted frame can also have one or more electric motors for automated adjustability of the slatted frame, for example the headboard or the footboard.

[0062] In any case, the tub advantageously has at least one ventilation opening, allowing for improved air circulation under the slatted frame. This design helps prevent moisture buildup and mold, promoting a healthy sleeping environment.

[0063] According to a further preferred embodiment of the invention, it is provided that the bed comprises a water mattress.

[0064] Thanks to its lightweight yet sturdy construction, the bed can also support a water mattress. The water mattress can rest on the slatted frame, for example, or on a specially designed support surface within the tub. Reinforcing the slatted frame may be necessary.

[0065] Using a water mattress can improve the quality of a user's sleep.

[0066] According to a further preferred embodiment of the invention, it is provided that the bed has at least one pressure drawer.

[0067] The at least one push-pull drawer represents a high-quality solution with a high aesthetic appeal for storing items such as bedding. The drawer opens with a gentle mechanical push, allowing for simple and intuitive operation. Since the drawer has no handle, it blends in with the high-quality appearance of the bed.

[0068] The at least one pressure drawer can be comparatively small and compact, but can also take up a large part of the base area of ​​the bed and, for example, be the size of a typical bed box.

[0069] According to a further preferred embodiment of the invention, it is provided that the bed has an electrical interface for supplying electrical energy and / or at least one socket and / or at least one light switch.

[0070] The bed can be supplied with electrical energy via the electrical interface for supplying electrical power, which is then distributed, for example, to the sockets and made available to other consumers. In this sense, light switches or lamps controlled by light switches are also considered consumers. A slatted frame with one or more electric motors, if present, is also considered a consumer in this sense and can be supplied via the electrical interface for supplying electrical power and, if applicable, a socket.

[0071] The at least one light switch can, for example, control a lamp dedicated to the bed, in particular a so-called reading lamp. Additionally or alternatively, a room lamp can also be controlled. In the latter case, the at least one light switch is preferably designed as a wireless switch, which allows control of the corresponding lamp even without a direct cable connection from the light switch to the lamp.

[0072] According to a further preferred embodiment of the invention, it is provided that the piece of furniture has a control unit which enables control of the electrical heating wires and / or the hydraulic temperature control lines and / or the decorative fountain and / or the display via a user interface.

[0073] The control unit, equipped in particular with a graphical user interface, enables centralized control of the electrical heating wires, the hydraulic temperature control lines, the decorative fountain, and the display. Users of the bed can thus easily adapt the bed's functions to their individual needs, for example, setting a suitable temperature, specifying the operating time of the decorative fountain, and controlling the display as needed.

[0074] The user interface can be designed as a touchscreen, for example. Operating the control unit via the user's smartphone is also conceivable and preferred, so that in this case the smartphone represents the user interface of the control unit. For this purpose, the smartphone can be paired with the control unit, for example, via Bluetooth and a corresponding app.

[0075] The invention further relates to a method for producing a piece of furniture according to the invention, comprising the steps

[0076] - Construction of an internal structure as a supporting frame and to specify an external shape of the piece of furniture,

[0077] - Applying an intermediate structure to the internal structure and

[0078] - Applying an external structure made of tiles, porcelain stoneware and / or natural stone slabs to the intermediate structure

[0079] The method according to the invention is characterized in that the piece of furniture is manufactured as a bed. The method according to the invention thus enables the production of the piece of furniture according to the invention and thus leads to the advantages already described.

[0080] According to a preferred embodiment of the invention, it is provided that individual elements of the internal structure are glued together.

[0081] This method of joining the individual elements of the interior structure is particularly suitable for Styrodur, rigid foam boards, and aerated concrete blocks. The use of adhesives specifically designed for these materials enables a robust and permanent connection of the components, contributing to the longevity and stability of the furniture.

[0082] According to a further preferred embodiment of the invention, a fabric layer and / or a nonwoven layer and / or electrical heating wires and / or hydraulic temperature control lines are bonded to the intermediate structure. These components can be permanently arranged on the intermediate structure in a simple and very reliable manner by means of bonding. They thus become an integral part of the intermediate structure.

[0083] According to a further preferred embodiment of the invention, it is provided that the inner structure is filled before the application of the intermediate structure and / or that the intermediate structure is filled before the application of the outer structure.

[0084] Filling ensures a smooth surface and eliminates any irregularities that could compromise the installation of the exterior structure or impair its appearance. Furthermore, filling with a suitable filler can also create a moisture barrier that limits the penetration of moisture beyond the intermediate structure.

[0085] According to a further preferred embodiment of the invention, it is provided that the outer structure is grouted after the tiles, porcelain stoneware and / or natural stone slabs have been applied.

[0086] This also protects the materials from moisture penetration. Furthermore, it can promote a uniform and elegant appearance of the bed. According to a further preferred embodiment of the invention, a continuous recess is inserted into the inner structure, the intermediate structure, and the outer structure at one foot end of the bed, into which a display can be lowered.

[0087] The implementation of the retractable display in the foot of the bed requires that a precisely designed recess is provided in the various layers of the bed structure during the manufacturing process.

[0088] It is therefore beneficial to consider the implementation of the display during the bed planning phase to determine the exact dimensions and positioning of the cutout. It is important to ensure that the cutout is large enough to accommodate the display while not compromising the structural integrity of the bed.

[0089] The invention is explained below by way of example with reference to embodiments shown in the figures.

[0090] They show:

[0091] Fig. 1 shows, by way of example and schematically, a possible embodiment of a piece of furniture according to the invention in a perspective view from,

[0092] Fig. 2 shows, by way of example and schematically, another possible embodiment of a piece of furniture according to the invention in a perspective view from the front,

[0093] Fig. 3 shows, by way of example and schematically, the bed of Fig. 1 in a perspective view from the side,

[0094] Fig. 4 shows an exemplary and schematic section through the tub of the bed and

[0095] Fig. 5 shows, by way of example and schematically, a possible embodiment of a method according to the invention for producing a piece of furniture in the form of a flow chart.

[0096] Identical objects, functional units, and comparable components are designated by the same reference symbols throughout the figures. These objects, functional units, and comparable components are identical in terms of their technical features, unless explicitly or implicitly stated otherwise in the description.

[0097] Fig. 1 shows, by way of example and schematically, a possible embodiment of a piece of furniture 10 according to the invention in a perspective view from the front.

[0098] As can be seen, the piece of furniture 10 is designed as a bed 10, namely a double bed 10. An outer structure 20 of the bed 10 consists, for example, of natural stone slabs 21. The natural stone slabs 21 are mitered at their edges or joints to convey a visually high-quality impression.

[0099] The outer structure 20 forms a trough 22 which has on its inside fastening devices (not shown in Fig. 1 ) for receiving a slatted frame (also not shown in Fig. 1 ).

[0100] In order to ensure ventilation of the slatted frame and a mattress that can be placed on the slatted frame, the tub 22 also has a plurality of ventilation slots (not shown in Fig. 1), which are arranged, for example, in the side walls of the tub 22.

[0101] At the foot end of the bed 10, on the top side of the rear wall of the tub 22, a recess 13, shown closed in Fig. 1, can also be seen. The recess 13 contains a display recessed into the recess 13, which can be extended from the recess 13 at the user's request.

[0102] The bed 10 also includes a back wall 11 arranged behind a headboard of the bed 10, which has a surface with the same natural stone slabs 21 as the bed 10. Two padded headrests 12, which have a leather surface, are also embedded in the back wall 11.

[0103] The bed 10 further comprises an intermediate structure 30 arranged within the outer structure 20, which intermediate structure 30 consists, for example, of a fleece layer and a filler layer and further comprises electrical heating wires.

[0104] Within the intermediate structure 30, the bed 10 of the figure also includes, for example, an inner structure 40 made of Styrodur. Since the inner structure 40 and the intermediate structure 30 are surrounded by the outer structure 20, they are not visible in the illustration in Fig. 1.

[0105] Fig. 2 shows, by way of example and schematically, another possible embodiment of a piece of furniture 10 according to the invention in a perspective view from the front.

[0106] The bed 10 of Fig. 2 differs from the bed 10 of Fig. 1, for example, by the presence of two decorative fountains 14, which are mounted on either side of the bed 10 in the rear wall 11. The decorative fountains 14 are operated by electric pumps recessed into the rear wall 11.

[0107] The babbling sound of the 14 decorative fountains can help you fall asleep. Furthermore, the 14 decorative fountains also have a positive effect on the humidity in the room.

[0108] The bed 10 of Fig. 2 further differs from the bed 10 of Fig. 1 by the presence of two bedside tables 15. The bedside tables 15 are mounted on both sides of the bed 10 and, for example, are connected equally to the tub 22 and the back wall 11. They also have an identical surface with the same natural stone slabs 21 as the bed 10.

[0109] In addition, the bed 10 of Fig. 2 has two light switches 17 and two sockets 18 in the rear wall 11, which are supplied with electrical energy via an electrical interface for supplying electrical energy (not shown in Fig. 3).

[0110] The light switches 17 are, for example, wireless light switches 17 that can control the lighting of the room in which the bed 10 is installed. By using wireless light switches 17, it is not necessary for a cable connection between the light switches 17 and the room's lighting.

[0111] Fig. 3 shows, by way of example and schematically, the bed 10 of Fig. 1 in a perspective view from the side.

[0112] In the illustration in Fig. 3, the retractable display 16 is also shown in the extended state. For example, the display 16 is designed to display an entertainment program, such as a television program or internet content. Also visible in the illustration in Fig. 3 is a push-pull drawer 19, which is designed as a bed base 19 and can be actuated by mechanical pressure.

[0113] Fig. 4 shows an exemplary and schematic section through the tub 22 of the bed 10.

[0114] You can see the inner structure 40, the intermediate structure 30 located above the inner structure 40 and the outer structure 20 located above the intermediate structure 30.

[0115] The inner structure 40 consists, for example, of rigid foam in the form of panels, with individual elements of the rigid foam being glued together to fundamentally define the outer shape of the bed 10. Since the inner structure 40 is made of rigid foam, it is a lightweight structure 40.

[0116] The inner structure 40 is surrounded by the intermediate structure 30, which, for example, consists of several individual layers or individual elements. Directly in contact with the inner structure 40 is a layer of filler 31, which enables good connection to the following fabric layer 32. The fabric layer 32 enables a certain degree of elasticity of the inner structure 40 compared to the outer structure 20, for example in the event of different thermal expansion. For example, hydraulic temperature control lines 33 are glued to the fabric layer 32. These lines can be used with hot water to heat the bed 10 or with cold water to cool the bed 10, as required. A further layer of filler 34 is arranged above the hydraulic temperature control lines 33, which seals off the intermediate structure 30 to the outside and enables good arrangement of the outer structure 20.

[0117] Finally, the outer structure 20 consists, for example, of porcelain stoneware 23, the edges or joints of which are covered with metallic rails 24. The metallic rails 24 are, for example, chrome rails 24.

[0118] Fig. 5 shows, by way of example and schematically, a possible embodiment of a method according to the invention for producing a piece of furniture 10 in the form of a flow chart.

[0119] In a first method step 101, aerated concrete blocks are first provided to construct an internal structure 40 as a supporting frame and to specify an external shape of the piece of furniture 10. The specification of the external shape is such that the piece of furniture 10 is manufactured as a bed 10.

[0120] In step 102, the aerated concrete blocks are cut into the required shape and glued together in step 103. Already in steps 102 and 103, a recess 13 is provided at the foot end of the bed 10, which will accommodate a display 16 when the bed 10 is finished.

[0121] In step 104, the materials for applying the intermediate structure 30 to the inner structure 40 are provided. For example, these are OSB boards, filler, and electrical heating wires.

[0122] In step 105, the OSB panels are attached to the inner structure 40, for example, by gluing. This ensures that the recess 13 in the foot end of the bed 10 remains accessible.

[0123] In step 106, the electrical heating wires are arranged on the OSB boards, for example also by gluing.

[0124] In the following step 107, the OSB boards and the electrical heating wires glued to them are filled with filler. Here, too, the recess 13 is left open.

[0125] In step 108, the materials for applying the outer structure 20 of tiles to the intermediate structure 30 are provided.

[0126] In step 109, the tiles are cut into the required shape, with the edges being mitred, for example.

[0127] Finally, in step 110, the tiles are glued onto the intermediate structure 30 and form the outer structure 20, again leaving the recess 13 free.

[0128] In step 111 the tiles are grouted.

[0129] In step 112, a mechanism for lowering and extending the display 16 is arranged in the recess 13.

[0130] Finally, in step 113, the display 16 is arranged in the recess 13 so that it can be lowered and extended.
