Abstract

PCT No. PCT/CH88/00079 Sec. 371 Date Dec. 14, 1988 Sec. 102(e) Date Dec. 14, 1988 PCT Filed Apr. 14, 1988 PCT Pub. No. WO88/08060 PCT Pub. Date Oct. 20, 1988.In bearing structures which can be converted from a rest shape to an operational shape of larger volume and have at least one flat bearing part (1) and at least one support part (2) movable with and/or detachable therefrom, the problem consists in achieving good shape retention and in particular high resistance to bending without affecting the geometrical adaptability. The solution is achieved through three features: (a) the flat bearing part (1) is essentially resistant to bending in the first normal plane (NE1) and comparatively flexible in at least a second normal plane (NE2) at an angle to the first normal plane; (b) the bearing part (1) has an at least sectionally-curved functional shape; (c) when the bearing structure is in its operational shape the support part (2) is connected in a push-resistant manner with at least one region of the bearing part (1) which extends at an angle to the first normal plane (NE1).

Description

Die Erfindung betrifft ein Sitzmöbel, das zwischen einer Ruheform und einer Funktionsform grösseren Volumens umstellbar ist gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a piece of seating furniture which can be switched over between a resting form and a functional form of larger volume in accordance with the preamble of patent claim 1.

Ein solches Sitzmöbel ist bekannt aus der DE-A-3 308 336. Bei dem bekannten Sitzmöbel sind die Tragelemente mit recht aufwendig ausgeführten und daher auch teuren sogenannten selbsthemmenden Taumelbeschlägen miteinander verbunden. Zur Veränderung der Form des Sitzmöbels müssen die Taumelbeschläge in aufwendiger Weise einzeln gelöst und wieder fixiert werden.Such seating is known from DE-A-3 308 336. In the known seating, the supporting elements are connected to one another with so-called self-locking wobble fittings which are very complex and therefore also expensive. To change the shape of the seating, the wobble fittings have to be loosened and fixed again in a complex manner.

Aufgabe der Erfindung ist die Schaffung eines Sitzmöbels der genannten Art, das sich unbeschadet seiner Umstellbarkeit zwischen einer Ruheform mit geringem Raumbedarf und einer Funktionsform grösseren Volumens durch hohe Formsteifheit und vor allem Biegesteifheit bzw. Biegefestigkeit auszeichnet. Auch soll das Umstellen schnell und einfach ausführbar sein. Die erfindungsgemässe Lösung dieser Aufgabe kennzeichnet sich durch die Merkmale des Anspruchs 1.The object of the invention is to provide a piece of seating furniture of the type mentioned which, without prejudice to its switchability between a form of rest with a small space requirement and a functional form of larger volume, is distinguished by high dimensional rigidity and, above all, bending stiffness or bending strength. The changeover should also be quick and easy to carry out. The solution to this problem according to the invention is characterized by the features of claim 1.

Bevorzugte Ausgestaltungen des erfindungsgemässen Sitzmöbels sind in den abhängigen Ansprüchen gekennzeichnet.Preferred configurations of the seating furniture according to the invention are characterized in the dependent claims.

Die Erfindung wird weiter anhand der in den Zeichnungen schematisch dargestellten Ausführungen erläutert. Hierin zeigt:

Fig. 1 zeigt unter a) - f) einen Tragkörper, welcher in seiner Funktionsform gemäss Fig. 1e) und f) ein Sitzmöbel darstellt. Der Tragkörper weist ein Tragteil 110 und ein Stützteil 120 auf. Sowohl das Tragteil 110 als auch das Stützteil 120 bestehen aus stabförmigen, biegesteifen, nebeneinanderliegenden Tragelementen 1a, 11 die an ihren einander benachbarten Längsseiten durch Gelenke 1b, 12, miteinander verbunden sind und zwar entsprechend Fig. 2 oder Fig. 3. In Fig. 3 sind die Tragelemente 11 als Hohlprofilstäbe mit trapezförmigem Querschnitt und die Gelenke 12 als Biegelemente ausgebildet. Das Stützteil ist mit einem Randabschnitt 111 des Tragteils schwenkbar verbunden, wobei zwischen den einzelnen aneinandergrenzenden Tragelementen des Tragteils und der Stutzteile jeweils einzelne Gelenke bzw. Scharniere 130 vorgesehen sind. Dadurch ist der Tragkörper als Ganzes aufrollbar. An den genannten Randabschnitt 111 des Tragteils 110 schliesst sich ein weiterer Abschnitt 112 grösserer Höhe an.Fig. 1 shows under a) - f) a support body, which in its functional form according to Fig. 1e) and f) represents seating. The support body has a support part 110 and a support part 120. Both the support part 110 and the support part 120 consist of rod-shaped, rigid, side-by-side support elements 1a, 11 which are connected to one another on their adjacent longitudinal sides by joints 1b, 12, in accordance with FIG. 2 or FIG. 3. In FIG. 3 the support elements 11 are designed as hollow profile bars with a trapezoidal cross-section and the joints 12 as bending elements. The support part is pivotally connected to an edge section 111 of the support part, individual joints or hinges 130 being provided between the individual adjoining support elements of the support part and the support parts. As a result, the support body can be rolled up as a whole. Another section 112 of greater height adjoins said edge section 111 of support part 110.

Unter a) zeigt Fig. 1 den Tragkörper zusammengerollt in seiner kompaktesten Ruheform, in der er leicht transportabel ist. Zur Überführung in die Funktionsform wird der Tragkörper teilweise aufgerollt. Das Stützteil 120 dient in der Funktionsform als Sitzfläche. Wie unter d) in Fig. 1 dargestellt wird das Stützteil 120 bei senkrecht stehendem Tragteil 110 in eine horizontale Lage geklappt. Anschliessend wird der weitere Abschnitt 112 des Tragteils 110 um das Stützteil 120 bündig herumgeführt und in dieser Stellung durch einen geeigneten Verschluss 140 (zwischen dem wieteren Abschnitt 112 und dem Randabschnitt 111) gesichert. Durch die Höhe des weiteren Abschnitts 112 des Tragteils 110 wird die Lehnenhöhe des Sitzmöbels bestimmt. Um das Stützteil 120 in seiner horizontalen Lage in der Funktionsform zu halten bzw. zu fixieren ist auf der Höhe des Stützteils im weiteren Abschnitt 112 des Tragteils 110 ein geeigneter Absatz oder eine zur Aufnahme des Umfangs des Stützteils 120 geeigneter Absatz oder eine zur Aufnahme des Umfangs des Stützteils 120 geeignete Nut oder Rinne vorgesehen, welche in Fig. 1b) und d) zu erkennen und mit 150 bezeichnet ist.Under a) Fig. 1 shows the support body rolled up in its most compact resting form, in which it is easily portable. The support body is partially rolled up for conversion into the functional form. In the functional form, the support part 120 serves as a seat. As shown under d) in Fig. 1, the support member 120 is folded into a horizontal position with the support member 110 standing vertically. Then the next one Section 112 of the support member 110 is guided flush around the support member 120 and secured in this position by a suitable closure 140 (between the further section 112 and the edge section 111). The backrest height of the seating furniture is determined by the height of the further section 112 of the support part 110. In order to hold or fix the support part 120 in its horizontal position in the functional form, a suitable shoulder or a shoulder suitable for receiving the circumference of the support part 120 or a shoulder for receiving the circumference is at the height of the support part in the further section 112 of the support part 110 of the support part 120 suitable groove or groove is provided, which can be seen in Fig. 1b) and d) and is designated 150.

Fig. 4 zeigt ausschnittweise eine erfindungsgemässe, zusammenlegbare Sitzbank 80 mit einem Tragteil 81 aus miteinander schwenkbar oder biegebeweglich verbundenen Tragelementen 81a. Die Aussteifung in der dargestellten Funktionsform erfolgt mittels Stützteilen 82 in Form von Querwänden, die ebenfalls aus miteinander schwenkbar oder biegebeweglich verbundenen Tragelementen 82a bestehen und wie vorbeschrieben mit dem Tragteil verbunden sind.FIG. 4 shows a section of a collapsible bench seat 80 according to the invention with a support part 81 made of support elements 81a which can be pivotally connected or bent. The stiffening in the functional form shown is carried out by means of support parts 82 in the form of transverse walls, which likewise consist of support elements 82a which are connected to one another so as to be pivotable or movable and which are connected to the support part as described above.
