Description

Die vorliegende Erfindung liegt auf dem Gebiet der Möbel und betrifft eine verstellbare Liege sowie einen Rahmen für eine solche Liege gemäss den Oberbegriffen der unabhängigen Patentansprüche.The present invention is in the field of furniture and concerns an adjustable couch and a frame for a such couch according to the generic terms of independent Claims.

Liegen, welche zwischen einer Liegeposition und einer Sitzposition verstellbar sind, wobei zwischen diesen beiden Extrempositionen noch Zwischenpositionen vorgesehen sein können, sind bekannt. Sie weisen einen Rahmen und eine Liegefläche auf, welche in Längsrichtung in mehrere Segmente unterteilt ist, wobei jeweils zwei benachbarte Liegeflächensegmente gelenkig miteinander verbunden sind. Zur Arretierung der gewünschten Kippposition wird üblicherweise ein auf dem Rahmen befestigter Zahnkranz verwendet, in welchen mit den Liegeflächensegmenten verbundene Stützen eingreifen. Diese Konstruktion hat den Nachteil, dass die Liegefläche notwendigerweise höher liegt als der Rahmen. Dies ist ästhetisch unbefriedigend und unpraktisch. Ausserdem stören auch der Zahnkranz und die Stützen die Ästhetik einer solchen Liege.Lying, which between a lying position and a Seating position are adjustable, taking between these two Extreme positions still be provided intermediate positions can, are known. They have a frame and a Lying surface, which in the longitudinal direction into several segments is divided, with two adjacent each Lying surface segments are hinged together. to Locking the desired tilt position is usually a ring gear attached to the frame is used, in which supports connected to the lying surface segments intervention. This construction has the disadvantage that the Lying surface is necessarily higher than the frame. This is aesthetically unsatisfactory and impractical. Moreover The sprocket and the supports also disturb the aesthetics of one such couch.

Die DE-521'742 zeigt ein Ruhebett mit drei gelenkig miteinander verbundenen Polsterteilen. Die Polsterteile sind mittels Lagerzapfen in Schlitten gelagert, welche Schlitten auf den Längsholmen des Rahmengestells verschiebbar gelagert sind. Die Schlitten werden mittels Klemmschrauben auf den Längsholmen festgestellt. Dieser Feststellmechanismus, der auf Kraftschluss zwischen den Klemmschrauben und den Längsholmen beruht, gewährleistet nicht immer die erforderliche Unbeweglichkeit der Polsterteile. Zur Erreichung der Unbeweglichkeit müssen die Klemmschrauben sehr fest angezogen werden, und zwar sowohl auf dem linken als auch auf dem rechten Längsholm. Die Verstellung des Ruhebetts wird dadurch mühsam und vom Bett selbst aus praktisch unmöglich.DE-521'742 shows a rest bed with three articulated interconnected cushion parts. The upholstery parts are stored by means of trunnion in slide, which slide slidably mounted on the longitudinal beams of the frame are. The carriages are clamped on the Longitudinal beams found. This locking mechanism, the on adhesion between the clamping screws and the Longitudinal beams is based, does not always guarantee the required immobility of the upholstery parts. to Achieving immobility, the clamping screws must be very be firmly tightened, both on the left and also on the right longitudinal spar. The adjustment of the couch becomes tedious and practical from the bed itself impossible.

Die US-6,138,303 offenbart ein Bett mit einer dreiteiligen Liegefläche. Die Liegeflächensegmente haben Lagerzapfen, welche in Längsschlitzen, die in den Längsholmen angebracht sind, verschiebbar sind.US 6,138,303 discloses a bed with a three-piece Lying area. The lying surface segments have bearing pins, which in longitudinal slots, which are mounted in the longitudinal beams are, are displaceable.

Die GB-556,353 zeigt ein Bettgestell mit einer dreiteiligen Matratze, deren Teile gelenkig miteinander verbunden sind. Der vordere Matratzenteil ist drehbar in den Längsholmen gelagert, während der hintere Matratzenteil in Längsrichtung in den Längsholmen verschiebbar ist. Die Feststellung erfolgt mittels eines am vorderen Matratzenteil angreifenden Arms. Dieser Feststellmechanismus gewährleistet zwar die Unbeweglichkeit der Matratzenteile, doch ist er auch nicht von einer auf dem Bett liegenden Person bedienbar.GB-556,353 shows a bedstead with a three-piece Mattress whose parts are hinged together. The front mattress part is rotatable in the longitudinal spars stored while the rear mattress part in the longitudinal direction is displaceable in the longitudinal beams. The determination takes place by means of an attacking on the front mattress arm. Although this locking mechanism ensures the Immobility of the mattress parts, but it is not operated by a person lying on the bed.

Denselben Nachteil hat auch das Bett, welches in der FR-1,270,426 offenbart ist. Das Bett weist drei gelenkig miteinander verbundene Matzratzenteile auf, von denen mindestens einer mittels in Längsrichtung verschiebbaren Lagerzapfen in den Längsholmen gelagert ist. Zur Feststellung dient ein am vorderen Matratzenteil angreifender Riegelmechanismus.The same disadvantage also has the bed which in FR-1,270,426 is disclosed. The bed has three hinged Matzratzenteile connected to each other, of which at least one longitudinally displaceable by means of Bearing journals is stored in the longitudinal beams. To determine serves an attacking on the front mattress part Locking mechanism.

Es ist daher Aufgabe der Erfindung, eine verstellbare Liege zu schaffen, deren Liegefläche in derselben Ebene liegt wie der Rahmen, und deren Ästhetik nicht durch zusätzliche Elemente wie einen Zahnkranz gestört wird. Die Position der Liegefläche soll unbeweglich arretierbar sein, und die Verstellung muss auf bequeme Art und Weise von einer auf der Liege liegenden Person ausführbar sein. Weiter ist es Aufgabe der Erfindung, einen Rahmen für eine solche Liege zu schaffen. Die Aufgabe wird gelöst durch die erfindungsgemässe Liege und den erfindungsgemässen Liegenrahmen, wie sie in den unabhängigen Patentansprüchen definiert sind. Vorteilhafte Ausführungsformen sind in den abhängigen Ansprüchen angegeben. It is therefore an object of the invention to provide an adjustable couch to create, whose lying surface lies in the same level as the frame, and its aesthetics not by additional Elements such as a ring gear is disturbed. The position of the The lying area should be immovably lockable, and the Adjustment must be in a comfortable way from one on the Lie lying person be executable. It's up to you to continue the invention, a framework for such a couch create. The object is achieved by the inventive Bed and the inventive bed frame, as in the independent claims are defined. advantageous Embodiments are in the dependent claims specified.

Figur 1 zeigt eine perspektivische Darstellung einer beispielhaften Ausführungsform der erfindungsgemässen verstellbaren Liege 1 in einer Liegeposition, Figur 2 in einer Zwischenposition. Die Liege 1 weist einen zwei parallele Längsholme 21, 22 umfassenden Rahmen 2 auf. Der Rahmen 2 ist in diesem Ausführungsbeispiel einstückig und hat die Form eines doppelten C, wobei jeweils ein Längsholm 21, 22 den mittleren Teil des C bildet und die beiden C an ihren Enden durch zwei Querholme 23, 24 verbunden sind. Der Rahmen 2 kann bspw. aus einem hohlen Metallrohr hergestellt sein. Weiter weist die Liege 1 eine Liegefläche 3 auf, welche in Längsrichtung in bspw. drei Segmente 31-33 unterteilt ist: ein Kopfsegment 31, ein Mittelsegment 32 und ein Fusssegment 33. Zwei benachbarte Liegeflächensegmente sind jeweils gelenkig miteinander verbunden. Die Liegefläche 3 bzw. jedes ihrer Segmente 31-33 kann einen an sich bekannten Lattenrost 34 beinhalten. FIG. 1 shows a perspective illustration of an exemplary embodiment of the adjustable couch 1 according to the invention in a lying position, FIG. 2 in an intermediate position. The couch 1 has a two parallel longitudinal beams 21, 22 comprehensive frame 2. The frame 2 is in this embodiment in one piece and has the shape of a double C, wherein in each case a longitudinal beam 21, 22 forms the middle part of the C and the two C are connected at their ends by two transverse bars 23, 24. The frame 2 may, for example, be made of a hollow metal tube. Next, the couch 1 on a lying surface 3, which is divided in the longitudinal direction in example. Three segments 31-33: a head segment 31, a middle segment 32 and a foot segment 33. Two adjacent lying surface segments are each hinged together. The lying surface 3 or each of its segments 31-33 may include a slatted frame 34 known per se.

In der in Fig. 1 dargestellten Liegeposition befinden sich alle drei Liegeflächensegmente 31-33 in der durch die beiden Längsholme 31, 22 definierten Liegeebene. In der in Fig. 2 dargestellten Zwischenposition ist das Kopfsegment 31 bezüglich einer ersten, in der Liegeebene liegenden Achse A aus der Liegeebene heraus gedreht, und das Mittelsegment 32 ist bezüglich einer zweiten, in der Liegeebene liegenden Achse B aus der Liegeebene heraus gedreht; das Fusssegment 33 befindet sich weiterhin in der Liegeebene, ist aber im Vergleich zur Liegeposition von Fig. 1 zum Kopfsegment 31 hin verschoben (vgl. auch Fig. 4). In einer (nicht gezeichneten) Sitzposition wären diese Drehungen des Kopfsegmentes 31 und des Mittelsegmentes 32 sowie die Verschiebung des Fusssegmentes 33 noch ausgeprägter vorhanden. Anhand der folgenden Figuren wird der Mechanismus erklärt, welcher gemäss der Erfindung die Verstellung der Liegefläche 3 ermöglicht.In the lying position shown in Fig. 1 are located all three lying surface segments 31-33 in by the two Longitudinal beams 31, 22 defined lying plane. In the in Fig. 2 illustrated intermediate position is the head segment 31st with respect to a first, lying in the lying plane axis A rotated out of the lying plane, and the middle segment 32nd is with respect to a second lying in the lying plane Axis B turned out of the lying plane; the foot segment 33 is still in the lying area, but is in the Comparison to the reclining position of Fig. 1 to the head segment 31 out shifted (see also Fig. 4). In a (not shown) Sitting position would be these rotations of the head segment 31 and the middle segment 32 and the displacement of the Foot segment 33 even more pronounced. Based on The following figures explain the mechanism which According to the invention, the adjustment of the lying surface. 3 allows.

Die Figuren 3 und 4 zeigen schematische Seitenansichten der Liege 1 von Fig. 1 und 2 in der Liegeposition bzw. in der Zwischenposition, wobei der Liegerahmen 2 der Übersichtlichkeit halber nur angedeutet und insbesondere der dem Betrachter zugewandte Längsholm 21 nicht eingezeichnet ist. Das Kopfsegment 31 ist um eine horizontale Achse A drehbar am Längsholm 31 befestigt. Das Fusssegment 33 ist, bspw. an zwei Führungspunkten C, D, im Längsholm 21 geführt. Das Mittelsegment 32 ist in diesem Ausführungsbeispiel nicht am Längsholm 21 befestigt. Figures 3 and 4 show schematic side views of the couch 1 of Fig. 1 and 2 in the lying position or in the intermediate position, the reclining frame 2 for the sake of clarity, only indicated and in particular the observer facing longitudinal beam 21 is not shown. The head segment 31 is rotatably mounted about a horizontal axis A on the longitudinal beam 31. The foot segment 33 is guided, for example, at two guide points C, D, in the longitudinal spar 21. The middle segment 32 is not attached to the longitudinal spar 21 in this embodiment.

Aus den Fig. 3 und 4 ist deutlich ersichtlich, wie sich die Entfernung zwischen dem Kopfsegment 31 und dem Fusssegment 33 verändert, wenn die Liege 1 in eine andere Kippposition gebracht wird. Jeder Kippposition ist eineindeutig eine Entfernung zwischen dem Kopfsegment 31 und dem Fusssegment 33 bzw. eine Verschiebung des Fusssegmentes 33 zugeordnet. Diese Verschiebung x ist durch die Formel x = α(1-cosβ)+b- b 2 - α2 sin2 β gegeben, wobei

a
die Entfernung zwischen der Drehachse A und dem hinteren Ende des Kopfsegmentes 31,
b
die Länge des Mittelsegmentes 32 und
β
der Kippwinkel des Kopfsegmentes 31
ist. Spezialfälle der Gleichung (1) sind:
  • 1. β = 0 ⇒ x = 0.
  • 2. β = 90° ⇒ x = α+b- b2-α2 (nur sinnvoll für a < b.)
  • From Figs. 3 and 4 it can be clearly seen how the distance between the head segment 31 and the foot segment 33 changes when the couch 1 is brought into another tilted position. Each tilt position is uniquely associated with a distance between the head segment 31 and the foot segment 33 and a displacement of the foot segment 33, respectively. This displacement x is given by the formula x = α (1-cosβ) + b - b 2 - α 2 sin 2 β given, where
    a
    the distance between the axis of rotation A and the rear end of the head segment 31,
    b
