Description

[0014] The invention is described in more detail hereinafter with reference to the exemplary embodiments shown in the accompanying drawings.

[0016] FIG. 1b shows schematically a perspective view of the piece of seating furniture according to a first exemplary embodiment obliquely from the front with two-part adjusting sliders which are released,

[0017] FIG. 2a shows a side view of FIG. 1a,

[0018] FIG. 2b shows a side view of FIG. 1b,

[0019] FIG. 3a shows a section of FIG. 2a,

[0020] FIG. 3b shows a section of FIG. 2b,

[0021] FIG. 4a shows the marked region of FIG. 3a enlarged,

[0022] FIG. 4b shows the marked region of FIG. 3b enlarged,

[0023] FIG. 5 shows the marked region of FIG. 3b enlarged and according to a second exemplary embodiment.

[0024] As FIG. 1a and FIG. 1b show, the invention relates to a piece of seating furniture having a base framework 1 and having a seat surface 2 fastened to the base framework 1 with one or more seating places 3 according to a first exemplary embodiment. The base framework 1 has a plurality of legs 4, 5, on the underside of each of which there is fastened an adjusting slider 6. The adjusting sliders then form the floor contact surface of the piece of seating furniture.

[0025] As in particular FIG. 4a and FIG. 4b show, according to the invention it is provided that at least two of the adjusting sliders 6 are of two-part design, each having a holding magnet 7 fastened to a leg 4, 5 of the base framework 1 and each having an adjusting slider cup 8 which can be fixed to a floor (not shown). The adjusting slider cup 8 has a cup receptacle 9 of a ferromagnetic material as an adhesive base, wherein the cup receptacle 9 and the holding magnet 7 can be placed one inside the other in a shape-adapted manner.

[0026] The at least two two-part adjusting sliders 6 are preferably provided on adjacent legs 4, 5, for example on two rear legs 4 or two front legs 5, or, however, on two right-hand legs 4, 5 or two left-hand legs 4, 5.

[0027] The respective adjusting slider cup 8 is preferably formed from a steel sheet. The adjusting slider cup 8 preferably has a flat floor positioning surface 10.

[0028] For fixing the adjusting slider cup 8 to a floor surface preferably a double-sided adhesive tape 11 made of a closed-cell polyethylene foam with acrylate adhesive is able to be attached to the adjusting slider cup 8, in particular to the floor positioning surface 10 thereof.

[0029] The holding magnet 7 in each case is preferably a permanent magnet made of a magnetic material with a high coercive field strength.

[0030] According to the exemplary embodiment shown, all of the adjusting sliders 6 of the legs 4, 5 may also be designed in two parts and with a holding magnet 7. In order to simplify the release of the magnetic connection it may be provided that a holding force of the holding magnets 7 of the adjusting sliders 6 for the front legs 5 is different from a holding force of the holding magnets 7 of the adjusting sliders 6 for the rear legs 4. Alternatively or additionally, a holding force of the holding magnets 7 of the adjusting sliders 6 for the right-hand legs 4, 5 may be different from a holding force of the holding magnets 7 of the adjusting sliders 6 for the left-hand legs 4, 5. The strengths of the magnetic holding forces are preferably different, such that the one strength is less than 35% of the other strength.

[0031] The respective holding magnet 7 is also preferably able to be fixed in a protective cap 12.

[0032] The base framework 1 may have legs 4, 5 which are arranged on frame legs 13 which are connected together via a transverse member 14. The transverse member 14 preferably supports a plurality of seating places 3 forming a seat bench.

[0033] In the exemplary embodiment shown in the figures, the piece of seating furniture is configured, for example, as a two seater bench. The base framework 1 has right-hand and left-hand framework legs 13 which, for example, bear a total of four legs 4, 5, two front legs 5 and two rear legs 4. At least the two front legs 5 are provided with an adjusting slider 6 which contains a holding magnet 7 as described above. The two holding magnets 7 are preferably strong permanent magnets. Two adjusting slider cups 8 which, for example, are configured as two compressed round plates and, for example, consist of a galvanized metal plate form the magnetically acting counter element. Due to the cup shape of the adjusting slider cups 8 a peripheral raised edge 15 (see FIG. 4b) is configured. If the adjusting slider cup 8 is configured, for example, as a plate, an annular edge which prevents the holding magnets 7 from slipping out of the cup is thus formed. The adjusting slider cups 8 of the at least front legs 5 are preferably fixed by the double-sided adhesive tape 11, for example onto a stone floor of a building, for example of an airport terminal.

[0034] The piece of seating furniture may thus be inserted with the holding magnets 7 into the adjusting slider cups 8. The effective magnetic force between the holding magnets 7 and the fixed adjusting slider cups 8 positions and fixes the piece of seating furniture, wherein at the same time said piece of seating furniture is secured against displacement.

[0035] A fastening of the holding magnets 7 to the leg 5 may, for example, be carried out by means of a screw fastening 16. To this end, a screw intermediate part 17 may be screwed into the leg.

[0036] According to a second exemplary embodiment of the piece of seating furniture, it is provided that the respective holding magnet 7 is fastened to the respective leg 4, 5 in an angularly movable manner. As shown in FIG. 5, the holding magnet 7 is able to be coupled, for example, in an angularly movable manner to the respective leg 4, 5 via an elastic intermediate part 18. The holding magnet 7 and the preferably provided screw intermediate part 17 are coupled via the elastic intermediate part 18 and a bolted connection, by means of the screw fastening 16. The screw intermediate part 17 is able to be screwed into a preferably vertically oriented screw hole 19 in the leg 4, 5. A contact surface 20 of the holding magnets 7 is thus angularly movable relative to the positioning plane of the piece of seating furniture which is determined by the floor and the cup receptacle 9 arranged thereon. A substantial air gap for freely positioning the holding magnet 7 with its contact surface 20 on a floor contact surface 21 of the cup receptacle 9 is ensured thereby, since it is possible to compensate for unevenness or other oblique positions. The locking force of the holding magnets 7 may be used substantially unimpeded, by the action of gravity of the piece of seating furniture which effects the angularly movable alignment of the holding magnet 7. Moreover, the embodiments relative to the first exemplary embodiment accordingly apply here.

[0037] According to a further exemplary embodiment, not shown further, for the angularly movable fastening of the holding magnet 7 on the respective leg 4, 5 a type of cardanic suspension may be provided alternatively or additionally to the elastic intermediate part 18. Moreover, the embodiments relative to the first exemplary embodiment accordingly apply here.
