DESCRIPTION OF THE INVENTION

The invention relates to a modular seating furniture having a first seating furniture element with a plurality of connector recesses, a second seating furniture element with a plurality of connector recesses and a connector unit for tool-free joining of the seating furniture elements. The connector unit comprises a base element forming a foot of the seat, a first connector pin opposite the foot element and a second connector pin opposite the foot element. In the assembled position of the chair, the first connector pin is inserted into a connector recess of the first seat furniture element and the second connector pin is inserted into a connector recess of the second seat furniture element.

If in this application of a seating is mentioned, this is a seating or a reclining furniture to understand. If in this application of a seating element is mentioned, it is to be understood as a seating furniture element or a reclining furniture element. This definition is useful to avoid the constant duplication of the terms "seating" and "reclining furniture". In addition, you can sit on any reclining furniture and on many chairs also lie. These two types of furniture, unlike other types of furniture (such as cupboards, shelves, sideboards and tables), are not for storing or storing objects, but for "storing" or "shutting down" people.

The connector unit is a Sitzmöbelelementverbindereinheit and designed so that the seating furniture elements connected to each other without tools, separated from each other and can be connected to each other or with other seating furniture elements to build another chair. Due to the flexible connector unit, the seating furniture can be very easily set up and dismantled by the end user at home. In the same simple manner but can also by another relative arrangement of the seating furniture elements to each other, an exchange of part of the seating furniture elements, an addition of seating furniture elements or the elimination of part of the seating furniture a chair with a different geometry and other properties by the end user without special technical knowledge or skills are assembled. The new modular seating thus adapts ideally to long-term changes in requirements such as: B. due to a move or the redesign of a room. But there are also short-term changes easily possible, such as the extension of a sofa for a common evening with friends TV.

The fixed and detachable connection between the seating furniture elements thus essentially takes place by inserting at least one connector pin of the connector unit into a corresponding connector recess of the first seat furniture element and the corresponding insertion of the second connector pin into a connector recess of the second seat furniture element. As a result, the seating furniture elements are connected together and at the same time ensures that the also present on the connector unit foot element can provide the supporting function of the foot of the chair and is located at the same height as the other feet of the chair. The connector units thus have a dual function, namely the joining of the seating furniture elements together and providing the feet of the chair.

The connector units can be inserted with play into the connector recesses. This clearance allows the user to insert and remove the connector units without tool and effort in the connector recesses. This results in a modular plug-in modular system with which comparatively complex seating furniture can be assembled and disassembled in just a few minutes.

The connector units may each comprise a connector plate having a first side and an opposite second side, wherein the foot member is disposed on the first side and the connector pins are disposed on the second side. The connector plate thus has a connective effect in two respects. It connects the connector pins with each other so that the seat furniture members are connected to each other via the connector pins inserted into the connector recesses and the connector plate connecting the connector pins. At the same time, the connector plate also connects the connector pins to the foot member.

The connector pins may have a circular cross section and an unprofiled surface. Accordingly, the connector recesses have a circular cross-section. Such holes can be particularly easy to bring into the seating furniture elements. The insertion of the connector pin in the circular holes is very simple. Since it is a tool-free assembly and disassembly, the surfaces of the connector pin and the connector recesses may be formed unprofiled. So they have in particular no thread.

The connector pins and the connector recesses may be cylindrical or conical. In a conical configuration, the connector pins taper toward their free end, and the connector recesses have their largest diameter at the beginning of the recess. Thereby, the connector pins can be particularly easily inserted into the connector recesses, without requiring an exact positioning of the connector unit to the seating furniture elements. Upon further insertion of the connector pin into the connector recesses, a self-centering effect then occurs due to the coordinated conicity.

The connector pins and the connector recesses may have a diameter or edge length of at least 10 mm. In particular, the diameter or the Edge length at least 15 mm, at least 20 mm or at least 25 mm. The maximum diameter or edge length is about 100 mm, about 80 mm, about 60 mm or about 40 mm. The diameter or the edge length is thus chosen so that the connector pin has the desired stability and is not in danger of breaking off.

Instead of a circular cross section, however, the connector pins may also have a rectangular, square, polygonal or elliptical cross section. The cross section is then matched to the cross section of the connector recess, so that the insertion of the connector pin into the respective connector recess is easily possible. In the case of a round or square cross-section, the connector pins are always inserted independently of the direction into the corresponding connector recess. In a rectangular cross section with different edge lengths or an elliptical cross section, a specific mounting direction is specified. This may be useful to prevent unwanted incorrect assembly of the connector units.

The connector unit has at least two connector pins. It can also have three, four, five, six, seven, eight, nine, ten or more connector pins. For geometric reasons, an integer number of connector pins is preferred. With four connector pin can be achieved particularly good results.

The connector recesses are juxtaposed in two different directions of the respective seating furniture element, namely the width and depth of the seating furniture element. As a result, the connector units can be attached to the seating furniture elements in two different positions or to fulfill two different functions. One position is the connection position. In this is at least one of the connector pin in a Verbinderausnehmung the first seat furniture element and at least one other connector pin in a recess of the second seat furniture element. But there is also a non-connecting position in which the connector unit only provides the foot function for the seating. This particularly concerns the areas of the seating furniture element to which no other seating furniture elements adjoin. In this case, the connector pins are thus used only in Verbehmerausnehmungen a seating furniture element. They can be arranged offset inwardly so seen in the width and depth of the seating furniture element that the connector units is not or only slightly visible.

The connector pins are spaced a first distance apart and the connector recesses are also spaced a first distance apart. Due to this uniform spacing, the universal use of the connector units in different places of the chair is possible. A wrong operation is excluded.

The connecting recesses are arranged in the edge region of the underside of the respective seating furniture element. The bottom of the seating furniture element is thus used for connection with other seating furniture elements. This is advantageous because the underside of the seating furniture element is not visible and thus no visually disturbing impression is created by the Verbinderausnehmungen. The arrangement of the connector recesses in the edge region means that the connector units have compact outer dimensions and provide the desired connection effect in the edge region.

The connector recesses are arranged side by side in two rows extending preferably over the entire length of the seating furniture element. This has the advantage that a high degree of variation is achieved by not only the corner regions or the ends of the seating furniture elements can be connected to each other, but also their central areas.

The connector recesses are disposed within the respective row at a constant first distance from each other and the connector recesses of the first row are located at the same first distance from the connector recesses of the second row. This ensures that a wrong insertion of a connector unit excluded and this can be used anywhere on the respective seating furniture element.

For the arrangement of the connector recesses in the underside of the seat furniture element, this can in particular consist of wood, plastic, metal or another material which is suitable for introducing the connector bores formed in particular as bores into the material. At this point, the seating so a base, in which the holes are introduced. The connector recesses can also z. B. are formed by a casting of metal or a plastic injection molded part.

The main body can extend over the entire underside. However, it can have a central depression if the connector recesses are arranged only in the edge region. At its other upwardly facing side of the main body is closed and in particular with a cushioning material, eg. As a fabric or leather related foam connected. This padding then forms the actual seat or the backrest or armrest. For the backrest or armrest, the cushioning material can also be reinforced. The seating can also be designed without upholstery. An example of this is a seat.

The first seating furniture element is a seat part and the second seating furniture element is a backrest or an armrest. Various combinations of these three basic elements make it possible to build many different types of seating. Examples include a corner sofa or a vis-à-vis sofa with 90 ° offset seating surfaces. In the seating furniture but it can also be another attachment for the seating, so z. B. a shelf, a side table or a footrest part.

The connector unit is in particular made of metal. But it could also consist of another material, which has the required strength and rigidity. So would be suitable, for example, plastic or wood.

The seating furniture may be a sofa, an armchair, a bench or a chaise longue. But it is also possible that the seating is a reclining furniture - so in particular a bed - is. Even with such a reclining furniture, the connector unit can be used to produce different lengths and widths as well as a headboard, footboard, side shelves, etc. to order.

DESCRIPTION OF THE FIGURES

Fig. 1 shows a first exemplary embodiment of a new modular chair 1 from above. Fig. 2 shows this chair 1 in a view from below.

The modular seating 1 has a plurality of seating furniture elements 2 which are connected to each other. In the present example, the modular seating 1 as a seating furniture elements 2, two seat parts 3, two back parts 4 and three armrests 5 on. In Fig. 1 one recognizes further a part of the feet 6 of the modular chair. 1

As in Fig. 2 It can be seen that each of the seating furniture elements 2 has a plurality of connector recesses 7. The connector recesses 7 are arranged side by side in two different directions of the respective seat furniture element 2, namely the width and the depth of the seat furniture element 2. The connector recesses 7 are arranged in an edge region 8 of the underside 9 of the respective seating furniture element 2. The connector recesses 7 are arranged at a constant distance from each other in the two directions. They extend substantially over the entire edge region 8 of the underside 9 of the respective seating furniture element 2. In the present case, they are arranged there in two rows next to one another. But it is also possible that they are arranged only in a row or in more than two rows.

The seating furniture elements 2 are connected to each other by connector units 10. In the example shown in FIG Fig. 2 These connector units 10 are formed differently. These different embodiments will be further described with reference to the following drawings. But it is also possible that with only one design of the connector unit 10 all connections between the seating furniture elements 2 are made.

Each of the connector units 10 has a connector plate 11 having a first side 12 and an opposite second side 13. On the first side 12, a foot member 14 is arranged. This foot member 14 forms one of the feet 6 of the chair. 1

For a more detailed construction of the connector unit 10 is now on the Fig. 3-18 referenced, in each of which two views of various exemplary embodiments of the connector unit 10 are shown.

It can be seen that a plurality of connector pins 15 are arranged on the opposite second side 13. The connector pins 15 are arranged at the same distance as the connector recesses 7. They correspond with the connector recesses 7 such that they can be inserted into them. This is done without tools and preferably with play, so that the seating furniture elements 2 can be very easily and quickly connected to each other by means of the connector units 10 and separated from each other.

In the present configuration example of Fig. 1 have the seat parts 3 and the back parts 4 in different directions, so that there is a vis-à-vis arrangement of the sofa formed. But there are any other configurations with these seating furniture elements 2 and the connector units 10 assembled.

It can be seen that in the mounted position of the seat 1, the connector units 10 are in contact with two seating furniture elements 2 and thus connect them to one another. The seating furniture elements 2 are based on the connector plate 11 and the foot member 14 on the floor.

The connector units 10 can be arranged according to the grid dimension of the connector recesses 7 at different locations along the edge regions 8 of the seating furniture elements 2. As long as the stability is not endangered, so the connector units 10 So also be easily seen in the depth of the chair 1 further inside, so that the feet 6 are barely visible or not at all. This results in a quasi hovering impression of the chair 1. It is also possible, in the depth of the chair 1 seen more connector units 10 between. This is particularly useful when the respective seating furniture element 2 has a comparatively large depth.

The construction of various exemplary embodiments of the connector unit 10 will now be described with reference to FIGS Fig. 3-18 explained in more detail, in which case essentially addresses the differences between the individual embodiments.

At the in Fig. 3 and 4 shown connector unit 10, the four connector pin 15 has a circular cross-section. The foot member 14 is arranged centrally.

At the in Fig. 5 and 6 shown connector unit 10, six connector pin 15 are present. These have a circular cross-section. The foot member 14 is arranged off-center.

In the Fig. 7 and 8th shown connector unit 10 has only two connector pin 15. These have a circular cross-section.

In the Fig. 9 and 10 shown connector unit 10 has four connector pin 15. These have a square cross-section.

In the Fig. 11 and 12 shown connector unit 10 has six connector pin 15. These have a circular cross-section. The foot member 14 is arranged off-center.

In the Fig. 13 and 14 shown connector unit 10 has only two connector pin 15. These have a square cross-section.

In the Fig. 15 and 16 shown connector unit 10 has eight connector pin 15. These have a circular cross-section.

In the Fig. 17 and 18 shown connector unit 10 has eight connector pin 15. These have a square cross-section.

Fig. 19 and 20 show another configuration example of the modular chair 1. In this case, a vis-à-vis arrangement of a sofa was also assembled, in contrast to Fig. 1 . 2 between the two seat parts 3 two armrests 5 are arranged. Thus, the back parts 4 move further away from each other.

In Fig. 21 and 22 is a further configuration example of the modular chair 1 shown. In this case, it is a corner sofa with a seat extended to a lying surface. It can also be seen in the view from below that the connector units 10 can also be arranged at those locations on the underside 9 of the seating furniture elements 2, to which no further seating furniture element 2 adjoins (see upper right area in FIG Fig. 22 ). The two connector units 10 shown there thus fulfill no connection function, but only the function of forming a foot 6 of the chair 1 by the foot members 14th
