Ein derartiges Möbel ist nach der US-A-2 257 754 bzw. der US-A-2 562 197 bekannt. Beim Gegenstand der erstgenannten Druckschrift ist das Bodenpolsterteil fest auf dem unteren Auflegerahmen angeordnet, während des bei dem anderen Dokument lose aufliegt.Such furniture is known from US-A-2 257 754 and US-A-2 562 197. In the subject of the first-mentioned document, the floor cushion part is fixedly arranged on the lower support frame, while the other document lies loosely.

Beide Möbel haben den Nachteil, daß sie wegen der scharfen überstehenden Rückenbeschlagteile des Ausklappmechanismus und der damit verbundenen Verletzungsgefahr nicht frei im Raum oder mit ihrer Rückseite als Raumtrenner in der Wohnung aufgestellt werden können. Nachteilig ist weiter, daß die Möbel eine große Bautiefe aufweisen, die auf den aufwendigen Ausklappmechanismus zurückzuführen ist. Das setzt große Wohnstellflächen voraus. Außerdem ist der Mechanismus zu kompliziert aufgebaut und weist eine Vielzahl von Scharnieren bzw. Verbindungsstellen, beweglichen Hebeln und Verstrebungen auf, wozu noch der gesamte Metallträgeruntersatz unter dem Möbel kommt. Der hohe Grundaufbau der Möbel hat weiter den Nachteil, daß die Sitz- und Rückenpolsterteile wegen ihrer niedrigen Bauhöhe, wenn die Sitzhöhe anatomisch richtig gewählt werden soll, nur mit einer Schaumgummipolsterung o. ä. ausgestattet werden kann, was die Einschränkung mit sich bringt, daß für sehr schwere Personen nur eine unzureichende Federkraft zur Verfügung steht. Die Möbel können auch in normalen Wohnungen nur in Ecken, Nischen oder Einbauwänden aufgestellt werden. Erschwert wird bei dieser Aufstellung, daß die Möbel zur Umwandlung in die Liegestellung insgesamt erst nach vorn gezogen werden müssen und dann nach hinten ausgeklappt werden können.Both pieces of furniture have the disadvantage that they cannot be set up freely in the room or with their backs as room dividers in the apartment because of the sharp protruding back fittings of the folding mechanism and the associated risk of injury. Another disadvantage is that the furniture has a large depth, which is due to the complex folding mechanism. This requires large living spaces. In addition, the mechanism is too complicated and has a large number of hinges or connection points, movable levers and struts, which also includes the entire metal support under the furniture. The high basic structure of the furniture has the further disadvantage that the seat and back upholstery parts, because of their low height, if the seat height is to be selected anatomically correctly, can only be equipped with foam rubber padding or the like, which entails the restriction that insufficient spring force is available for very heavy people. Even in normal apartments, the furniture can only be installed in corners, niches or built-in walls. This arrangement makes it more difficult that the furniture must first be pulled forward to convert it into the lying position and then it can be folded out to the rear.

Der Erfindung liegt die Aufgabe zugrunde, die erwähnten Nachteile zu beseitigen.The invention has for its object to eliminate the disadvantages mentioned.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der innere Auflegerahmen mit der hinteren unteren Kante des unteren Auflegerahmens und der äußere Auflegerahmen mit dem Wandteil scharnierartig verbunden ist.This object is achieved in that the inner support frame is hinged to the rear lower edge of the lower support frame and the outer support frame to the wall part.

Das erfindungsgemäße Möbel weist den Vorteil auf, daß Auszugsmechanismus und Polsterteile mit einem einfachen Handgriff in die Liegestellung gebracht werden können. Außerdem ist der Mechanismus einfach aufgebaut, und die Polsterteile kommen mit dem Boden nicht in Berührung.The furniture according to the invention has the advantage that the pull-out mechanism and upholstery parts can be brought into the lying position with a simple handle. In addition, the mechanism is simple and the upholstery parts do not come into contact with the floor.

Nach einer zweckmäßigen Ausgestaltung der Erfindung ist der untere Auflegerahmen durch Haltegurte mit dem äußeren Auflegerahmen lösbar verbunden. Die Haltegurte wiederum können in der Liegestellung mit dem Rückenpolsterteil lösbar verbunden sein.According to an expedient embodiment of the invention, the lower support frame is releasably connected to the outer support frame by means of holding straps. The straps can in turn be releasably connected to the back cushion part in the lying position.

Weiterhin kann das Rückenpolsterteil an seiner Rückenanlehnfläche ein in halber Höhe an einem Scharnierpunkt angelenktes keilförmiges Polster aufweisen, das in der Liegestellung umgeklappt ist und zusammen mit dem Rückenpolsterteil ein quaderförmiges Polster mit horizontaler Liegefläche ergibt.Furthermore, the back cushion part can have on its backrest surface a wedge-shaped cushion articulated at half a height to a hinge point, which is folded down in the lying position and together with the back cushion part results in a cuboid-shaped cushion with a horizontal lying surface.

Nach einer weiteren Ausgestaltung der Erfindung ist ein Scharnier zwischen dem unteren Auflegerahmen und dem äußeren Auflegerahmen vorgesehen, das einen lösbaren Haltedrehstift aufweist.According to a further embodiment of the invention, a hinge is provided between the lower support frame and the outer support frame, which has a releasable retaining pivot pin.

Nach Fig. 1 besteht das Sitz- und Liegemöbel aus einem Bodenpolsterteil 1 und einem Sitzpolsterteil 2, welche an ihrer hinteren Kante durch ein Scharnier 4 miteinander verbunden sind. Auf dem Sitzpolsterteil 2 steht ein Rückenpolsterteil 3. Das Bodenpolsterteil 1 ist auf einem mit Rollen 6 versehenen unteren Auflegerahmen 5 angeordnet. Die hintere Abstützung der Polster erfolgt durch einen äußeren Auflegerahmen 8, der, wie Fig. 2 zeigt, in die Liegestellung ausziehbar ist. Der äußere Auflegerahmen 8 und der untere Auflegerahmen 5 sind durch Haltegurte 11 verbunden. Diese können stabile Gummigurte oder kombinierte Gurte sein, die beim Anlehnen an das Rückenpolsterteil 3 eine Federwirkung ausüben.1, the seating and reclining furniture consists of a floor cushion part 1 and a seat cushion part 2, which are connected to one another at their rear edge by a hinge 4. A back cushion part 3 stands on the seat cushion part 2. The floor cushion part 1 is arranged on a lower support frame 5 provided with rollers 6. The rear support of the upholstery is provided by an outer support frame 8 which, as shown in FIG. 2, can be pulled out into the lying position. The outer support frame 8 and the lower support frame 5 are connected by tethers 11. These can be sturdy rubber straps or combined straps when leaning on exert a spring effect on the back cushion part 3.

Entsprechend Fig. 2 ist innerhalb des äußeren Auflegerahmens 8 ein innerer Auflegerahmen 7 angeordnet, welcher Stützfüße 9 zum Abstützen in der Liegestellung aufweist. Beide Rahmen sind scharnierartig miteinander verbunden.2, an inner support frame 7 is arranged within the outer support frame 8, which has support feet 9 for support in the lying position. Both frames are hinged together.

Es ist auch möglich, daß die beiden Rahmen 7, 8 seitlich am unteren Auflegerahmen 5 mit Scharnieren verbunden sind. Dann muß allerdings auch das Scharnier 4 seitlich angeordnet sein, so daß das Sitzpolsterteil 2 zur Seite geklappt werden kann.It is also possible that the two frames 7, 8 are connected laterally on the lower support frame 5 with hinges. Then, however, the hinge 4 must also be arranged laterally so that the seat cushion part 2 can be folded aside.

In Fig.3 wird gezeigt, daß der gesamte Auszugsmechanismus, der aus den Rahmen 5, 7, 8 besteht, in der Liegestellung als Auflage für die Polsterteile 1, 2, 3 dient. Das lose aufgelegte und als Kopfpolster dienende Rückenpolster 3 wird durch die Haltegurte 11, welche mit ihrem einen Ende am äußeren Auflegerahmen 8 befestigt sind, gegen Verrutschen fixiert. Das Rückenpolsterteil 3 bildet das Liegepolster. Am Rückenpolsterteil ist in halber Höhe in einem Scharnier 15 ein keilförmiges Polster 14 angelenkt. Dieses Polster wird in der Liegestellung, wie Fig. 3 zeigt, in die andere Richtung geklappt. Beide Polster 3, 14 ergeben sodann ein quaderförmiges Gebilde mit horizontaler Liegefläche. Der äußere Auflegerahmen 8 ist durch ein Scharnier 16 mit dem Wandteil 17 verbunden, so daß Rollen am äußeren Auflegerahmen 8 entfallen können und der Auszugsmechanismus durch einfaches Ziehen von dem Wandteil 17 weg in die Auszugstellung gebracht wird.In Figure 3 it is shown that the entire pull-out mechanism, which consists of the frames 5, 7, 8, serves as a support for the cushion parts 1, 2, 3 in the lying position. The loosely placed back cushion serving as a head cushion 3 is fixed against slipping by the holding straps 11, which are attached at one end to the outer support frame 8. The back cushion part 3 forms the lying cushion. A wedge-shaped cushion 14 is articulated at half the height in a hinge 15 on the back cushion part. In the lying position, as shown in FIG. 3, this cushion is folded in the other direction. Both cushions 3, 14 then result in a cuboid structure with a horizontal lying surface. The outer support frame 8 is connected by a hinge 16 to the wall part 17, so that rollers on the outer support frame 8 can be omitted and the pull-out mechanism is brought into the pull-out position by simply pulling away from the wall part 17.

In Fig. 4 wird gezeigt, daß das Bodenpolsterteil 1 nicht auf den unteren Auflegerahmen 5 aufgepolstert ist, sondern auf diesem lose aufliegt. Bei dieser Konstruktion ist es möglich, den Auszugsmechanismus zusammenzuklappen, so daß das Möbel leicht, beispielsweise in einem Pkw, transportiert werden kann. Fig. 7 zeigt die entsprechende Transportstellung. In Fig. 5 ist die Liegestellung für Fig. 4 dargestellt. Nach Fig. 6 sind der untere und der äußere Auflegerahmen 5, 8 durch Scharniere 12 verbunden, welche je einen lösbaren Haltedrehstift 13 aufweisen. Mit dieser Ausbildung werden die Verwendungsmöglichkeiten des Möbels beim Transport durch Verringerung der Sperrigkeit und Verteilung des Transportvolumens erweitert.In Fig. 4 it is shown that the floor cushion part 1 is not padded onto the lower support frame 5, but rests loosely on this. With this construction, it is possible to fold the pull-out mechanism so that the furniture can be easily transported, for example in a car. Fig. 7 shows the corresponding transport position. 5 shows the lying position for FIG. 4. 6, the lower and the outer support frame 5, 8 are connected by hinges 12, each having a releasable retaining pin 13. With this training, the possible uses of the furniture during transport are expanded by reducing the bulk and distribution of the transport volume.
