Die Tischplatte 2 hat etwa die Form eines gleichseitigen Dreiecks mit drei Längsseiten 3, 4, 5, wobei die Ecken 6 der Tischplatte 2 abgerundet sein können.The table shown in the drawing has a table frame 1 and a Table top 2 on. The table top 2 has approximately the shape of an equilateral Triangle with three longitudinal sides 3, 4, 5, wherein the corners 6 of the table top. 2 can be rounded.

Das Gestell 1 weist drei vertikale Tischbeine 7, 8, 9 auf, die sich über Rollen 10 auf dem Boden abstützen. Ein Tischbein 7 weist einen horizontalen oberen Stützarm 11 auf, der durch Abbiegen des das Tischbein 7 bildenden Rohres gebildet ist. Dieser Stützarm 11 ist mittels eines Schwenk-Gelenks 12 mit dem Tischbein 8 derart verbunden, daß das Tischbein 8 um seine vertikale Mittel-Achse 13 relativ zum horizontalen Stützarm 11 mit dem Tischbein 7 verschwenkbar ist. Unmittelbar unterhalb des Schwenk-Gelenks 12 ist am Tischbein 8 ein weiterer horizontaler unterer Stützarm 14 angebracht, der einstückig mit dem dritten Tischbein 9 durch entsprechendes Abbiegen das das Tischbein 9 mit dem Stützarm 14 bildenden Rohres ausgebildet ist. Dieser Stützarm 14 liegt unmittelbar unterhalb des Stützarms 11, wobei im in einer Ebene zusammengeklappten Zustand das Tischbein 9 mit unterem Stützarm 14 innerhalb des durch die Tischbeine 7, 8 und den oberen Stützarm 11 gebildeten nach unten offenen U angeordnet sind. Die Tischbeine 7, 8, 9 samt den Stützarmen 11, 14 lassen sich also in eine gemeinsame Ebene klappen. Um die Mittel-Achse 13 sind auch die Rohre 10 schwenkbar.The frame 1 has three vertical legs table 7, 8, 9, which are about roles Support 10 on the ground. A table leg 7 has a horizontal upper support arm 11, by bending the table leg 7 forming Tube is formed. This support arm 11 is by means of a pivot joint 12 connected to the table leg 8 such that the table leg 8 to his vertical center axis 13 relative to the horizontal support arm 11 with the Table leg 7 is pivotable. Immediately below the swivel joint 12 is on the table leg 8 another horizontal lower support arm 14 mounted integrally with the third table leg 9 by appropriate Turn the table leg 9 forming with the support arm 14 Tube is formed. This support arm 14 is located directly below the Support arm 11, wherein in the folded state in a plane the Table leg 9 with lower support arm 14 within the by the table legs 7, 8 and the upper support arm 11 formed downwardly open U arranged are. The table legs 7, 8, 9 together with the support arms 11, 14 can thus be in to work out a common plane. To the center axis 13 are also the Tubes 10 pivotable.

Die Tischplatte 2 ist mittels zweier Schwenk-Gelenke 15, 16 an dem oberen Stützarm 11 derart schwenkbar angelenkt, daß sie einerseits in eine herunterhängende Position (siehe Fig. 3) und andererseits in eine zumindest angenähert senkrecht nach oben gerichtete Position (siehe Fig. 7) verschwenkbar ist. Die Schwenk-Gelenke 15, 16 sind um die durch die horizontale Mittel-Achse des Stützarms 11 gebildete, gemeinsame Schwenk-Achse 17 schwenkbar, die parallel zur benachbarten Längsseite 3 der Tischplatte 2 verläuft.The table top 2 is by means of two pivot joints 15, 16 at the top Support arm 11 hinged so pivotally that they on the one hand in a drooping Position (see Fig. 3) and on the other hand in an at least approximately vertically upward position (see FIG. 7) is pivotable. The pivot joints 15, 16 are around by the horizontal center axis of the support arm 11 formed, common Pivoting axis 17 pivotally parallel to the adjacent longitudinal side. 3 the table top 2 runs.

Wenn die Tischbeine 7, 8, 9 in eine Standposition des Tisches auseinandergeschwenkt und die Tischplatte 2 in ihre horizontale Stellung hochgeklappt ist (siehe Fig. 1, 5), dann stützt sich die Tischplatte 2 auf dem unteren Stützarm 14 durch eine Halte- und Abstütz-Einrichtung 18 ab. Diese weist einen Abstütz-Bügel 19 auf, der etwa die Form eines nach unten offenen U aufweist und am unteren Stützarm 14 möglichst nah zum Übergang 20 vom unteren Stützarm 14 in das Tischbein 9 angebracht ist. Der Bügel 19 weist einen oberhalb des unteren Stützarms 14 befindlichen Quersteg 21 auf. An der Unterseite 22 der Tischplatte 2 ist ein Halteteil 23 angebracht, das einen Aufnahmeschlitz 24 für den Quersteg 21 des Abstütz-Bügels 19 aufweist. Das Halteteil 23 ist in der Nähe der Längsseite 4 der Tischplatte 2 angebracht, zu der hin der untere Stützarm 14 mit dem Tischbein 9 zum Aufstellen des Tisches verschwenkt wird. Die Tischplatte 2 wird hierzu etwas über ihre horizontale Position hinaus hochgeschwenkt und dann nach dem Auseinanderklappen der Tischbeine 7, 8, 9 wieder abgesenkt, so daß der Aufnahmeschlitz 24 des Halteteils 23 den Quersteg 21 des Abstütz-Bügels 19 aufnimmt, wodurch die Position des unteren Stützarms 14 mit dem Tischbein 9 relativ zur Tischplatte 2 und damit auch relativ zu den beiden anderen Tischbeinen 7, 8 fixiert wird.When the table legs 7, 8, 9 are pivoted apart in a standing position of the table and the table top 2 folded up in its horizontal position is (see Fig. 1, 5), then the table top 2 is supported on the lower Support arm 14 by a holding and supporting device 18 from. These has a support bracket 19, which is approximately in the shape of a downwardly open U has and on the lower support arm 14 as close to the transition 20 is mounted from the lower support arm 14 in the table leg 9. Of the Bracket 19 has a located above the lower support arm 14 Crossbar 21 on. At the bottom 22 of the table top 2 is a holding part 23rd attached, which has a receiving slot 24 for the transverse web 21 of the support bracket 19 has. The holding part 23 is in the vicinity of the longitudinal side 4th attached to the table top 2, towards the lower support arm 14 with the Table leg 9 is pivoted to set up the table. The tabletop 2 is this swung up slightly beyond its horizontal position and then lowered again after the unfolding of the table legs 7, 8, 9, so that the receiving slot 24 of the holding part 23, the cross bar 21st the support bracket 19 receives, whereby the position of the lower support arm 14 with the table leg 9 relative to the table top 2 and thus also relatively is fixed to the other two table legs 7, 8.

Zwischen dem oberen Stützarm 11 und dem an der Unterseite 22 der Tischplatte 2 befestigten, dem Schwenk-Gelenk 15 zwischen dem Tischbein 8 und dem oberen Stützarm 11 benachbarten Schwenk-Gelenk 16 ist eine Rast-Kupplung 25 angeordnet, die einerseits ein Verschwenken der Tischplatte 2 um die Mittel-Achse 13 des oberen Stützarms 11 erlaubt, andererseits aber die Tischplatte 2 in dem annähernd vertikalen, hochgeklappten Zustand (siehe Fig. 7) hält. Diese Rast-Kupplung 25 weist eine Hülse 26 auf, die auf dem oberen Stützarm 11 in Richtung von dessen Mittel-Achse 13 unverschiebbar und gegen Verdrehen festgelegt ist. In der Hülse 26 ist ein in Richtung der Mittel-Achse 13 verschiebbarer Kupplungs-Ring 27 angeordnet, der mittels in der Hülse 26 abgestützter vorgespannter Druckfedern 28 aus der Hülse 26 heraus in Richtung auf das Schwenk-Gelenk 16 herausgedrückt wird. Der Kupplungs-Ring 27 ist in der Hülse 26 undrehbar geführt, ist also auch gegenüber dem oberen Stützarm 11 nicht um die Mittel-Achse 13 drehbar. Am zugeordneten Schwenk-Gelenk 16 ist ein Kupplungs-Gegenring 29 angebracht, der dem Kupplungs-Ring 27 gegenüberliegt und mit dem Schwenk-Gelenk 16 und damit mit der Tischplatte 2 um die Mittel-Achse 13 verschwenkt wird. Der Kupplungs-Ring 27 und er Kupplungs-Gegenring 29 weisen an ihren einander zugewandten Seiten jeweils eine Verzahnung 30 und eine Gegen-Verzahnung 31 auf, die einander komplementär sind. Wenn die Verzahnung 30 und die Gegen-Verzahnung 31 ineinander greifen, dann können der Kupplungs-Ring 27 und er Kupplungs-Gegenring 29 nicht gegeneinander um die Mittel-Achse 13 verschwenkt werden. Wenn der Gegenring 29 durch Aufbringung einer entsprechend großen Kraft auf die Tischplatte 2 gegenüber dem Ring 27 verschwenkt wird, was beim Hoch- bzw. Herunterklappen der Tischplatte 2 der Fall ist, dann wird durch die zwischen der Verzahnung 30 und der Gegen-Verzahnung 31 wirkende Kraft der Kupplungs-Ring 27 jeweils gegen die Kraft der vorgespannten Druckfedern 28 in die Hülse 26 zurückgeschoben. Wenn die Verzahnungen 30, 31 dann jeweils in komplementäre Überdeckung kommen, drücken die Druckfedern 28 den Gegenring 29 wieder in den Ring 27. Die von den Druckfedern 28 aufgebrachten Kupplungskräfte sind jedenfalls so groß, daß die Tischplatte 2 in der in Fig. 7 dargestellten weitestgehend hochgeschwenkten Position gehalten wird. Die Rast-Kupplung fixiert auch die Position der Tischplatte 2 in ihrer horizontalen Stellung, wenn der Quersteg 21 sich in dem Aufnahmeschlitz 24 befindet.Between the upper support arm 11 and the bottom 22 of the Table top 2 attached, the pivot joint 15 between the table leg 8 and the upper support arm 11 adjacent pivot joint 16 is a latching clutch 25 is arranged, on the one hand pivoting the Table top 2 allows about the central axis 13 of the upper support arm 11, on the other hand but the table top 2 in the approximately vertical, folded up Condition (see Fig. 7) stops. This latching coupling 25 has a Sleeve 26 which, on the upper support arm 11 in the direction of its central axis 13 is immovable and fixed against rotation. In the Sleeve 26 is a sliding in the direction of the center axis 13 clutch ring 27 arranged by means supported in the sleeve 26 biased Compression springs 28 out of the sleeve 26 in the direction of the Swing joint 16 is pushed out. The coupling ring 27 is in the sleeve 26 is non-rotatably guided, so it is also opposite the upper support arm 11 is not rotatable about the central axis 13. At the associated pivot joint 16, a coupling mating ring 29 is attached to the coupling ring 27 is opposite and with the pivot joint 16 and thus is pivoted about the central axis 13 with the table top 2. The coupling ring 27 and he coupling mating ring 29 point to each other facing sides each have a toothing 30 and a counter-toothing 31, which are complementary to each other. If the gearing 30 and the counter-teeth 31 interlock, then can the coupling ring 27 and he coupling mating ring 29 is not against each other be pivoted about the central axis 13. When the mating ring 29 by applying a correspondingly large force on the table top. 2 is pivoted against the ring 27, which when folding up or down the table top 2 is the case, then by the between the Gearing 30 and the counter-toothing 31 acting force of the coupling ring 27 respectively against the force of the prestressed compression springs 28th pushed back into the sleeve 26. If the gears 30, 31 then Comes in complementary overlap, press the springs 28 the mating ring 29 back into the ring 27. The of the compression springs 28th applied clutch forces are anyway so large that the table top 2 in the largely swung-up position shown in Fig. 7 is held.
