Description

[0001] The invention relates to a modular sofa with the features of the preamble of claim 1.

[0002] Patent EP 1 893 053 B1 discloses a modular sofa with detachably connected seat sections and detachably connected back and side sections. The seat sections, back sections, and side sections have box-shaped base sections with cushions, over which covers are pulled. The box-shaped base sections of the seat sections have intermediate shelves at a mid-height of the base sections, which are framed on all sides by upright walls such that the base sections have open cavities at the top and bottom. Cushions are placed in the open cavities of the base sections of the seat sections of the known modular sofa, and a further cushion is placed on top of this cushion. The covers are pulled over this further cushion up to a lower edge of the box-shaped base sections, which hold the upper cushions in place on the base sections.

[0003] The object of the invention is to propose a simple method for attaching a slipcover to a seat, backrest, and / or side panel of a modular sofa of the aforementioned type. Preferably, the slipcover should be attachable and detachable by hand without tools.

[0004] This problem is solved according to the invention by the features of claim 1.

[0005] The sofa according to the invention has a modular structure, comprising a seat and a backrest, and in embodiments of the invention, additionally a side panel. Several seat, backrest, and / or side panels can also be combined and connected to form a sofa.

[0006] According to the invention, the seat section and / or the back section and / or the side section has a cavity open at the bottom, and the modular sofa has a cover for the seat section, the back section, and / or the side section. The "cover" is a covering, for example, made of textile, leather, or a plastic material, such as a non-woven fabric containing microfibers, which is pulled over the seat section, the back section, and / or the side section from the top down to an underside. Preferably, the cover lies completely, mostly, or largely against the surfaces of the seat section, back section, and / or side section that it covers, in particular the side surfaces, backrests, tops, and / or seating surfaces of the seat section, back section, and / or side section. For a detachable fastening, the cover is folded over at the bottom into the cavity open at the bottom of the seat section, back section, and / or side section and detachably secured in the cavity.

[0007] Underneath the slipcover, a slipcover-like, for example padded, cover may be pulled over the seat, backrest and / or side panel.

[0008] Spatial directions such as "below" and "above" refer to the intended placement of the seat or sofa with its feet on the floor or another, particularly horizontal, surface. The floor, or more generally the surface, is considered "below" in relation to the sofa.

[0009] For example, for washing or replacement, the cover can be detached from the seat, back and / or side panels and pulled upwards.

[0010] The cover does not need to extend all the way down on all sides; it is sufficient if, for example, it extends down only on three sides or on two opposite sides of the seat, backrest, and / or side panel. For instance, the cover does not need to extend all the way down on the back of the backrest or on the sides of the seat, backrest, and / or side panel facing another seat, backrest, or side panel. However, the cover preferably extends down on all sides of the seat, backrest, and / or side panel, is preferably folded over on all sides into the open cavity of the seat, backrest, and / or side panel, and is preferably detachably secured in the cavity on all sides – preferably by hand without tools.

[0011] Preferably, the cover can be attached and detached by hand without tools in the open cavity on the underside of the seat, backrest, and / or side panel. For example, the cover is detachably attached with hook-and-loop fasteners to the inside of an enclosure of the open cavity on the underside of the seat, backrest, and / or side panel, or hung on hooks or similar devices.

[0012] One advantage of the invention is the possibility of manufacturing its individual components, such as covers, cushions, base components, and so on, from a single material. After disassembling the sofa, the individual parts can therefore be easily recycled or disposed of.

[0013] In embodiments of the invention, the backrests and side panels can be identical, resulting in a modular sofa with fewer different components. In this case, the backrest can also be used as a side panel. However, different backrests and side panels are also possible. For example, in this embodiment of the invention, the side panels are lower than the backrests.

[0014] The dependent claims relate to advantageous embodiments and further developments of the invention.

[0015] In a preferred embodiment of the invention, the cover has a loop at its lower edge, which is folded over from the outside inwards into the open cavity at the bottom of the seat, back, and / or side section of the modular sofa, and then upwards within the cavity. In particular, a threading rod is or is pulled through the loop at the folded lower edge of the cover and secured to an inner surface of an enclosure of the open cavity on the underside of the seat, back, and / or side section, for example, by being hooked onto pins or hooks.

[0016] The loop consists in particular of a flexible, two-dimensional sheet structure and preferably extends along the lower edge of the cover and is interrupted only at the pins or hooks into which the threading rod is or is hooked. For example, the cover has a loop interrupted at the pins or hooks, or loops between the pins or hooks, on opposite sides or on all sides of the seat section and on opposite sides of the back section and / or the side section. In particular, a threading rod is inserted through the loop(s) of the cover on each side of the seat section and on opposite sides of the back section and / or the side section and hooked onto the pins, hooks, or the like on the inside of the cavity's enclosure.

[0017] A preferred embodiment of the invention provides that the seat, backrest, and / or side panel has a box-shaped base that provides stability to the seat, backrest, and / or side panel. The base has an intermediate shelf and upright walls that enclose the intermediate shelf like a frame or casing. "Upright" means that the walls of the base are vertical or approximately vertical when the sofa is placed on the floor or, more generally, the surface it is positioned on, as intended, or that the walls are perpendicular or approximately perpendicular to the intermediate shelf of the base. The walls of the base extend upwards and / or downwards beyond the intermediate shelf in such a way that a cavity open at the top and bottom is formed above and below the intermediate shelf.The open-bottomed cavity beneath the intermediate shelf of the base section forms the open-bottomed cavity of the seat section of the modular sofa according to the invention. In embodiments of the invention, the box-shaped base section of the back section and / or the side section of the modular sofa according to the invention has similar open-bottomed cavities on their undersides. The walls of the base section, projecting downwards beyond the intermediate shelf, form the enclosure of the open-bottomed cavity, to the inner sides of which the covers are detachably attached, for example, by hooking the threading rods inserted through the loops at the lower edge of the cover. In particular, the base section is not painted for recycling, no staples, screws, or nails are used, and the slipcover-like upholstery covers and the slipcovers do not have zippers, snap fasteners, eyelets, or the like that would need to be removed before recycling or disposal.

[0018] While the box-shaped base is primarily cuboid, other shapes, such as round ones, are also possible. The walls of the box-shaped base project upwards and / or downwards from the intermediate shelf, particularly at right angles. However, other angles are also possible. Walls with a polygonal, angular shape are not essential to the invention; the base can, for example, also have a continuous cylindrical or otherwise round wall projecting downwards and / or upwards from the intermediate shelf at a right angle or another angle. The wall can, for example, also have the shape of a single-shell hyperboloid, and in principle, the wall or the box-shaped base can have any shape, provided that the downward-opening cavity for folding the cover from the outside into the cavity in which the cover is fixed is present on the underside.Preferably, however, the box-shaped base part has a cuboid shape, as described above.

[0019] The seating section has a seat at the top and feet at the bottom, allowing it to be placed on a surface such as the floor. The "bottom" faces the floor or other surface, and the "top" faces away from the floor or other surface when the seating section or sofa is positioned as intended, with its feet resting on the floor or other surface. Here, "seat" refers to an element or upper surface of the seating section designed and intended for a person to sit on. The top of the seating section provides a seating surface. If the seating section has a box-shaped base, the feet of the seating section are positioned, particularly on the underside of the intermediate shelf, projecting downwards from it.The underside of the intermediate shelf faces the floor or, more generally, the floor surface, and the top side of the intermediate shelf faces away from the floor or, more generally, the floor surface, when the sofa or seat is positioned as intended with its feet on the floor or, more generally, the floor surface.

[0020] The backrest of the modular sofa according to the invention is arranged on the rear side of the seat section, where "rear side" refers to the side of the seat section on which the backrest is arranged. The backrest has a backrest on its front side, where "front side" refers to the side of the backrest facing the seat section. The backrest is a surface designed for the back of a person sitting on the sofa or on the seat section of the sofa, and it typically extends vertically or at an acute angle to a vertical line from the top of the seat section upwards on the rear side of the seat section.

[0021] The backrest also has feet on an underside, with which it supports itself on the floor or generally the surface when the sofa according to the invention is set up with its feet on the floor or generally on the surface as intended.

[0022] In a preferred embodiment of the invention, the feet of the seat and backrest are rigidly and detachably connected to one another such that the backrest is connected to the seat via the rigid connection of the feet. The seat supports the backrest in an upright position. The feet of the backrest can be arranged in an imaginary, for example, vertical plane such that the backrest alone, without the seat, is not stable on the floor or, more generally, on the surface it is placed on.

[0023] "Detachable" means that the feet can be separated from each other without damage or destruction and reconnected to each other in their original manner or with the original, unaltered components, without replacing any parts. In particular, the feet of the seat, backrest, and – if present – ​​side panel can be separated from each other and rigidly reconnected without tools, either by hand or with a simple hand tool such as a wrench (e.g., open-end, box-end, or Allen wrench).

[0024] As described, several seat and back sections can be connected to each other by means of a detachable and rigid connection of their feet to form the modular sofa according to the invention, thus making it possible, for example, to create a wider sofa and / or a corner sofa or a U-shaped sofa. The seating area can also be extended by placing another seat section on the front side opposite the back of one seat section and furthest from the back.

[0025] One embodiment of the invention provides for a detachable and rigid connection of the feet of the seat, backrest, and—if present—the side panel to a brace or stiffener that rigidly connects a foot of the seat to a foot of another seat, backrest, and / or side panel, or a foot of a backrest to a foot of a side panel, wherein the brace or stiffener is detachable from the feet. A brace, for example, comprises two or more struts that connect the two feet, for example, in the manner of a flat ladder frame. The struts can, for example, be screwed to the feet. A stiffener, for example, comprises a flat plate whose farthest edges are rigidly and detachably connected to the feet, for example, by screws.

[0026] One embodiment of the invention features a side part that is or is arranged on a side of the seat part adjacent to its rear, here referred to as the side edge. Like the back part, the side part projects upwards beyond the upper surface of the seat part, which forms the seat surface, and the side part has feet on its underside that are rigidly and detachably connected to feet of the seat part and / or the back part, such that the side part is connected to the seat part and / or the back part via these interconnected feet. The side part—like the back part—does not need to stand stably on the floor or, more generally, the surface it is placed on, for example, the floor or the surface it is placed on, for example, the floor, by virtue of the connection of its feet to the feet of the seat part and / or the back part.

[0027] In embodiments of the invention, the seat sections are not rigidly connected at their feet, but rather with connectors that are attached or connected to a seat section only after the seat sections have been erected. In this way, the backrests and side panels can be attached to the seat sections, and individual seat sections with their attached backrests and side panels can be erected—that is, placed with their feet on the floor or, more generally, the surface. It is therefore not necessary to erect the sofa as a whole. The erected seat sections are pushed together on the floor or surface as they are to be arranged as a sofa and connected with the connectors. A tensile-strength connection of the seat sections that prevents them from shifting relative to one another is sufficient.

[0028] Preferably, the seat section(s) are self-supporting, whereas the back section(s) and side sections are not self-supporting in embodiments of the invention. "Self-supporting" means that the seat section stands securely on, for example, the floor or, more generally, the surface it is placed on. For this purpose, the feet are arranged on the underside of the seat section such that they rest, for example, at the corners of an imaginary triangle, and preferably an imaginary rectangle or square, on the floor or, more generally, the surface it is placed on. Viewed perpendicularly from above, the feet should not be positioned too far inwards from the sides of the seat section on the floor or, more generally, the surface it is placed on, so that the seat section does not tip over when weight is applied to one edge. The invention does not preclude other arrangements of the feet.

[0029] In embodiments of the invention, the feet of the backrest and / or side panel rest on an imaginary straight line on the floor or, more generally, the surface on which the backrest or side panel is not stable on the floor or, more generally, the surface on which it stands when it is standing alone and its feet are not connected to feet of the seat, side panel or backrest.

[0030] The feet of the backrest or side panel are preferably not connected to all the feet of the seat, but rather to feet located on the underside of the seat, close to the side of the seat where the backrest or side panel is or will be located. Preferably, at least two feet of the backrest or side panel are rigidly and detachably connected to two feet of the seat, or to at least one foot of the seat and one foot of a side panel or backrest.

[0031] A further development of the invention provides that the walls of the box-shaped base of the seat section of the sofa according to the invention project upwards from the intermediate floor such that the box-shaped base has a cavity on the intermediate floor that is open at the top and enclosed laterally by the walls. A cushion for the seat of the sofa, or as a seat cushion for a person sitting on the sofa, is arranged in this cavity, the cushion preferably projecting upwards beyond the walls of the box-shaped base of the seat section. The walls of the box-shaped base, projecting upwards from the intermediate floor, prevent the cushion from slipping laterally in all directions.

[0032] Preferably, the seat component has a cushion made of elastic foam with a cavity open at its underside, in which a suspension system is or is arranged, which, for example, comprises spring cores. The suspension system can also, like the cushion, consist of elastic foam, whereby separate manufacturing of the cushion and the suspension system allows for different spring or cushion firmness levels for the cushion and the suspension system.

[0033] The slipcover covers or stretches over and holds the cushion on the seat, backrest, and / or side panel. The slipcover allows for easy attachment of the cushion to the seat, backrest, and / or side panel. Furthermore, the slipcover determines the appearance / color of the sofa according to the invention.

[0034] In preferred embodiments of the invention, the backrest and / or side panel of the modular sofa have a box-shaped base that extends upwards beyond the top of the seat. This embodiment provides a sofa with a stable backrest, armrest, or side panel for leaning against or supporting a person sitting on the sofa. The box-shaped base of the backrest or side panel has a cavity on one side facing the seat, which is open on the other side. The side of the base facing the seat is referred to as the front of the backrest, and the side facing the seat is referred to as the inside of the side panel. A back cushion or side cushion can be arranged in the cavity, preferably protruding from the cavity.

[0035] All features mentioned in the description and / or illustrated in the drawing can be implemented individually or in any combination in embodiments of the invention. Embodiments of the invention that do not include all, but only some, of the features of a claim, including an independent claim, are possible.

[0036] The invention is explained in more detail below with reference to an embodiment illustrated in the drawing. The drawing shows: Fig. 1 a perspective view of a modular sofa according to the invention, taken obliquely from above; Fig. 2 the sofa out Fig. 1 diagonally from below; Fig. 3 a perspective view of basic parts of a seat section with a back section and a side section of the modular sofa made of Fig. 1 and Fig. 2 diagonally from below; Fig. 4 a perspective exploded view of a seat section of the sofa made of Fig. 1 and Fig. 2 diagonally from below; Fig. 5 a sectional view of a detail of the seat part made of Fig. 4; Fig. 6 a perspective exploded view of a back or side panel of the sofa made of Fig. 1 and Fig. 2 diagonally from below; Fig. 7 two feet of the sofa connected by means of a strut according to the invention Fig. 1 or Fig. 2 in a perspective view; and Fig. 8 a connection of three sofa seat sections made of Fig. 1 and Fig. 2.

[0037] The in Fig. 1 and Fig. The sofa 1 shown in Figure 2, according to the invention, has a modular structure and comprises at least one seat section 2 and one back section 3. In the exemplary embodiment, the sofa 1 has three seat sections 2, two back sections 3, and one side section 4. The seat sections 2 are cuboid and, viewed from above, square or rectangular. The seat sections 2 can be of different sizes. In the exemplary embodiment, the seat sections 2 are arranged in an L-shape when viewed from above, such that the sofa 1 forms a corner sofa. In principle, any number of seat sections 2 can be arranged in a square or rectangular grid.

[0038] Fig. Figure 3 shows box-shaped basic parts 5, 16 with feet 12 of a seat part 1, a back part 3 and a side part 4 of the modular sofa 1 diagonally from below.

[0039] The box-shaped base part 5 of the seat parts 2 is in Fig. Figure 4 shows an exploded view: it has a square or rectangular panel as an intermediate shelf 6, which has walls 7 on all four sides that enclose the intermediate shelf 6 in the manner of a square or rectangular frame. The walls 7 are arranged perpendicular to each other and perpendicular to the intermediate shelf 6 and project from the intermediate shelf 6 on both sides, i.e., upwards and downwards. Thus, the box-shaped base 5 of the seating sections 2 of the sofa 1 according to the invention has an upper cavity within the walls 7 on a top surface of the intermediate shelf 6 and a lower cavity 10 within the walls 7 on a bottom surface 11 of the intermediate shelf 6. The upper cavity is open upwards and the lower cavity 10 downwards. The walls 7 form an enclosure 28 of the cavities 10 above and below the intermediate shelf 6 of the box-shaped base 5.

[0040] Feet 12 are arranged on the underside 11 of the intermediate floor 6 of the base part 5, projecting downwards beyond the frame-like walls 7 of the box-shaped base part 5 (see also Fig. 2 and Fig. 3) The seat 2, or sofa 1, is placed on a floor (not shown) or, more generally, on a surface such that its feet 12 rest on the floor or surface. The feet 12 are positioned close to the sides of the seat 2, that is, close to the walls 7 of the box-shaped base 5, such that the seat 2 stands stably and securely on its feet 12, preventing it from tipping over. The seat 2 can therefore also be considered freestanding.

[0041] In the exemplary embodiment, the seat section 2 has four feet 12 arranged at the corners of an imaginary square or rectangle, the sides of which are parallel to the walls 7 of the box-shaped base 5 of the seat section 2 and slightly offset inwards from the walls 7 on the underside 11 of the intermediate shelf 6. The arrangement of the feet 12 is not mandatory; however, it is important or at least advantageous to arrange the feet 12 near the edges so that the seat section 2 stands securely on the feet 12.

[0042] The underside 11 of the intermediate shelf 6 and the seat section 2 is defined here as the side on which the feet 12 are located and which face the floor or, more generally, the floor surface when the seat section 2 or the sofa 1 is positioned as intended with its feet 12 resting on the floor or, more generally, the floor surface. The top side 8 is correspondingly the opposite side, facing away from the floor or, more generally, the floor surface. The side facing the floor or, more generally, the floor surface is referred to as "bottom" and the side facing away from the floor or, more generally, the floor surface as "top" when the seat section 2 or the sofa 1 is positioned as intended with its feet 12 resting on the floor or, more generally, the floor surface.

[0043] A cuboid cushion 13 is arranged on the upper surface 8 of the box-shaped base 5 of the seat section 2 of the modular sofa 1 according to the invention. The outer surfaces of this cushion are flush with the outer surfaces of the walls 7 of the box-shaped base 5. The outer surfaces of the cushion 13 have recesses that are as wide as the walls 7 of the box-shaped base 5 are thick, such that the cushion 13 engages in the upper cavity of the box-shaped base 5 between the four walls 7 and is thereby held against lateral displacement, i.e., against displacement in all directions parallel to the intermediate shelf 6 (see also Fig. 5).

[0044] The cushion 13 is higher than the upper cavity of the box-shaped base 5 of the seat part 2, and is deep from the upper edges of the walls 7 to the intermediate floor 6 such that the cushion 13 extends upwards over the walls 7 of the box-shaped base 5 when the cushion 13 lies between the walls 7 on the intermediate floor 6 of the box-shaped base 5.

[0045] The cushion 13, which in this embodiment consists of an elastic foam, has a cuboid cavity 14 with a square or rectangular base on its underside facing the intermediate shelf 6 of the box-shaped base 5 of the seat section 2 of the sofa 1. A suspension system 15 is arranged in this cavity, which in this embodiment comprises spring cores 9. The suspension system can, for example, also be a cushion such as the cushion 13, in whose cavity 14 the suspension system 15 is arranged on the underside. In this case, the suspension system 15 preferably has a different spring or cushion firmness than the cushion 13. The suspension system 15 rests on the intermediate shelf 6 of the box-shaped base 5 of the seat section 2 and is as high as the cavity 14 in the underside of the foam cushion 13, such that the foam cushion 13 rests on the suspension system 15.

[0046] The back panel 3 and the essentially identical side panel 4 - which is in Fig. The backrest 3 and side panel 4, as shown in Figure 6, each have a box-shaped base 16, which is or will be positioned upright against the sofa 1. "Upright" means that the base 16 of the backrest 3 and side panel 4 is taller than it is deep. "Deep" refers to the dimension of the backrest 3 and side panel 4 perpendicular to a side of the seat 2 to which the backrest 3 or side panel 4 is attached. The base 16 of the backrest 3 and side panel 4, and thus also the backrest 3 and side panel 4 themselves, extend upwards above the top surface 8 of the seat 2 or above a top surface 8 of the cushion 13 of the seat 2, such that a person sitting on the seat 2 can lean against the backrest 3 and side panel 4.

[0047] Fig. Figure 6 shows individual parts of the backrest 3, with the side panel 4 having the same construction. The base 16 of the backrest 3 has a cavity 17 above the upper surface 8 of the cushion 13 of the seat 2, which is open on a front side of the backrest 3 facing the seat 2. A back cushion 18 is arranged in the cavity 17 of the backrest 3 and projects from the backrest 3. A front side of the back cushion 18 facing the seat 2 forms a backrest 19 against which a person sitting on the cushion 13 of the seat 2 can lean.

[0048] The base part 16 of the side part 4, like the base part 16 of the back part 3, has a cavity 17 above the top surface 8 of the cushion 13 of the seat part 2, which is open on an inner side of the side part 3 facing the seat part 2. A cushion of the side part 4 is constructed identically to that of the back part 3, can be considered a side cushion, and is located on the side of the side part 4 facing the seat part 2, which is referred to here as the inner side.

[0049] On their undersides, the base 16 of the back panel 3 and the side panel 4 has feet 12, which in the exemplary embodiment are arranged in an imaginary vertical median plane or in a plane parallel to the median plane of the base 16 of the back panel 3 and the side panel 4. Because of the arrangement of the feet 12 in one plane, the back panel 3 and the side panel 4 do not stand stably on their own with their feet 12 on the floor or generally the surface they are placed on, but are very likely to fall over, i.e. the back panel 3 and the side panel 4 are not self-supporting on their own.

[0050] In the illustrated and described embodiment of the modular sofa 1 according to the invention, the back parts 3 and the side part 4 are identical in construction, i.e. there is no difference between the back part 3 and the side part 4, but a back part 3 is arranged as a side part 4 on the side of a seat part 2 and is connected to this and preferably also to the back part 3 at the rear of the seat part 2 as described.

[0051] However, it is also possible to design the sofa 1 according to the invention with different backrests 3 and side panels 4. For example, the side panels 4 are lower than the backrests 3 (not shown).

[0052] One - or if the seat section 2 is used as a corner element of a corner sofa - two back sections 3 and - if present - one side section 4 are connected to a seat section 2 via the feet 12 on their undersides 11. Fig. Figure 3 shows the connections between a seat section 2, a back section 3, and a side section 4. The connections are made as shown in... Fig. 3 and Fig. 7 to be seen - two feet 12 each, or for connecting a seat section 2 with a back section 3 and a side section 4 as in Fig. Figure 3, bottom left, shows three feet 12 connected "at an angle" by a brace 20. In this embodiment, the brace 20 has two rods 21 arranged parallel to each other and horizontally, i.e., parallel to the intermediate shelf of the seat section between the two feet 12, and screwed to the feet 12. The brace 20 connects the feet 12 rigidly and detachably. Together with the brace 20, the two feet 12 form a kind of flat ladder frame. Other connections, for example with a different brace or a plate-shaped stiffener between the feet 12, are possible (not shown). The feet 12 are detachably connected so that the seat section(s) 2, back section 3, and side section 4 of the modular sofa 1 according to the invention can be detached from one another and connected to each other in virtually any combination.

[0053] To loosen and connect the seat parts 2, back parts 3, and side parts 4, only a wrench such as an open-end wrench, ring wrench, or Allen wrench is required. Alternatively, the two feet 12 can be connected and detached without tools using, for example, bayonet fittings, hand levers, wing nuts, wing screws, or star knob screws.

[0054] Two feet 12 on one side of a seat part 2 are connected to the two feet 12 of a back part 3 or a side part 4, or one foot 12 of a seat part 2 is connected to a foot 12 of a back part 3 or a side part 4, the other foot 12 of which is connected to a foot 12 of another back part 3 or side part 4 or seat part 2.

[0055] After connecting the back sections 3 and the side sections 4, the seat sections 2 are set up, that is, placed with their feet 12 on the floor or other surface. Then the seat sections 2 are pushed together as they will be when assembled as a sofa 1 and connected with clamp-like connectors 29, as shown in the detailed illustration in Fig. 8 shows. Fig. Figure 8 shows an inside corner between three seat sections 2 of a corner sofa, viewed obliquely from below. In the exemplary embodiment, the connectors 19 are Z-shaped. One leg of the connector 29 is attached to a foot 12 of a seat section 2 of the sofa 1, for example, by screwing it on. Another leg 30 of the connector 29 extends upwards to the side of the seat section 2. The connector 29 is preferably attached to its feet 12 before the seat section 2 is placed on its feet.

[0056] After the seat sections 2 have been erected, an adjacent seat section 2 is placed onto the connector 29 such that one of the walls 7 of the box-shaped base 5 overlaps the upward-pointing leg 30 of the connector 29, thereby connecting the two seat sections 2 with their sides abutting each other in a tensile-resistant manner. Lateral chamfers 31 on the upward-pointing legs 30 of the connector 29 align the seat sections 2 with each other during connection.

[0057] It is also possible to connect the seat sections 2 of the sofa 1 according to the invention with struts 20 or stiffeners at their feet 12, as with the back sections 3 and the side sections 4. However, the sofa 1 must then be placed on its feet 12 as a whole, which is why connecting the seat sections 2 after assembly is considered advantageous.

[0058] Preferably, before joining the components, a slipcover-like upholstery cover 22 and then a slipcover 23 are pulled over the seat sections 2, back sections 3, and side sections 4 of the modular sofa 1 according to the invention. The upholstery covers 22 extend down the sides of the box-shaped base sections 5, 16 of the seat sections 2, back sections 3, and side sections 4 to the lower edges of the box-shaped base sections 5, 16, thereby also covering the cushions 13. The slipcovers 23 are made, for example, of fabric, leather, or plastic, for example, of a non-woven fabric containing microfibers.

[0059] The slipcover-like cushion covers 22 and the slipcovers 23 can also be pulled over the bases 5, 16 and the cushions 13, 14, 18 of the seat sections 2, back sections 3, and side sections 4, even when the base sections 5, 16 are connected. For example, it is not necessary to separate the seat sections 2, back sections 3, and side sections 4 from each other to wash or change the cushion covers 22 and the slipcovers 23; instead, the cushion covers 22 and the slipcovers 23 can be removed from and replaced on the connected seat sections 2, back sections 3, and side sections 5. Before removing the slipcovers 23, the threading rods 25 must be unhooked from the pins 26 in the open cavities 10 of the box-shaped base sections 10, or the threading rods 25 must be pulled out of the loops 24 of the slipcovers 23.

[0060] The slipcovers 23 are covers which, like the cushion covers 22, are pulled from above over the box-shaped base parts 5, 16 of the seat parts 2, back parts 3 and side parts 4, covering the cushions 13 and at the lower edges of the box-shaped base parts 5, 16 as in Fig.4 can be seen folded inwards and then upwards again. On their lower, folded-inwards and upwards again on inner sides 27 of the walls 7 of the box-shaped base parts 5, 16 of the seat parts 2, back parts 3 and side parts 4, the covers have 23 loops 24. The walls 7 of the box-shaped base parts 5, 16 form enclosures 28 of the lower cavities 10 of the box-shaped base parts 5, 16 of the seat parts 2, back parts 3 and side parts 4 of the modular sofa 1 according to the invention. Threading rods 25 are or are inserted through the loops 24, which are or are hung on pins 26 or hooks inside at the bottom of the walls 7 or enclosures 28 of the lower cavities 10 of the box-shaped base parts 5 of the seat parts 2, back parts 3 and side parts 4 of the modular sofa 1, whereby the covers 23 are detachably attached to the seat parts 2, back parts 3 and side parts 4.In the exemplary embodiment, the loops 24 are flexible, flat structures that extend along the inner sides 27 of the enclosures 28 of the lower cavities 10 of the base parts 5, 16 of the seat parts 2, back parts 3 and side parts 4, along the folded-over lower edges of the covers 23, and are interrupted only in the area of ​​the pins 26 or hooks on which the threading rods 25 are attached. The covers 23 can be attached to and detached from the seat parts 2, back parts 3 and side parts 4 by hand without tools.

[0061] On the back sides of the back sections 3 facing away from the seat sections 2, the cushion covers 22 and the slipcovers 23 need not cover the back sections 3. Likewise, on the front sides of the back sections 3 facing the seat sections 2 and on the inner sides of the side sections 4, the cushion covers 22 and the slipcovers 23 may end at the tops 8 of the seat sections 2.

[0062] The covers 23 hold the cushions 13, 18 in the cavities 17 of the box-shaped base parts 5, 16 of the seat parts 2, the back parts 3 and the side parts 4.

[0063] The modular sofa 1 according to the invention can be assembled and disassembled using only a wrench as the sole tool, or in embodiments of the invention without any tools. QUOTES INCLUDED IN THE DESCRIPTION
