Description

Die Erfindung betrifft ein Kombinationsmöbel gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to combination furniture according to the preamble of patent claim 1.

Aus der DE-PS-1 181 876 ist ein solches, allerdings in erster Linie als Sofa, also als Sitzmöbel ausgebildetes Kombinationsmöbel bereits bekannt. Zum Verschwenken in die horizontale Lage sind dabei die Seitenholme des Rückenteils nach unten verlängert und mit ihren unteren Enden am Rahmen des Sitzteils angelenkt. In der Normalstellung, also als Rückenlehne, ist das Rückenteil mittels Stützanker nach rückwärts abgestützt, die einmal am unteren Bereich der Seitenholme und zum anderen am hinteren Ende des Traggestells angelenkt sind. Beim Niederschwenken des Rückenteiles schwenken somit die Stützlenker gleichzeitig um ihre untere horizontale Achse und schieben somit das Rückenteil - und über dieses auch das Sitzteilgegenüber der Traggestell nach vorne, so daß also das Sitzteil und das Rückenteil je zum Teil auf bzw. über dem Traggestell zu liegen kommen.From DE-PS-1 181 876, such a combination furniture, which is primarily designed as a sofa, that is to say as seating furniture, is already known. To pivot into the horizontal position, the side members of the back part are extended downwards and articulated with their lower ends on the frame of the seat part. In the normal position, i.e. as a backrest, the back part is supported backwards by means of support anchors which are articulated on the lower area of the side rails and on the other hand at the rear end of the support frame. When the back part is swiveled down, the support arms simultaneously pivot about their lower horizontal axis and thus push the back part - and also the seat part - forward over the support frame, so that the seat part and the back part each lie partly on or above the support frame come.

Abgesehen davon, daß der Rückenteil relativ schmal ist, entsprechend der Höhe der Rückenlehne eines Sofas, so daß die vom Rückenteil gebildete "Rückenliege" nur sehr schmal ist, wäre es sehr erwünscht, wenn das Möbel auch als Einzelliege mit normaler Breite verwendet werden könnte. Zwar kann man natürlich auf einem Sofa, wie beispielsweise demjenigen gemäß DE-PS-1 181 876 auch liegen, und zwar auf dem Sitzteil, jedoch ist zu bemängeln, daß der Sitzteil als Liege zu schmal ist. Obwohl sich der Sitzteil nach rückwärts unter dem Rückenteil weiter nach hinten erstreckt, steht als Liegefläche doch nur die Breite von der vorderen Kante bis zur Rückenlehne zur Verfügung, diese Breite ist aber festgelegt durch die übliche "Sitztiefe", also das anatomische Maß von den Kniekehlen bis zum Rücken der Benutzer.Apart from the fact that the back part is relatively narrow, corresponding to the height of the back of a sofa, so that the "back bed" formed by the back part is only very narrow, it would be very desirable if the furniture could also be used as a single bed of normal width. Of course, one can also lie on a sofa, such as that according to DE-PS-1 181 876, on the seat part, but it should be criticized that the seat part is too narrow as a bed. Although the seat part extends backwards under the back part, only the width from the front edge to the backrest is available as a lying surface, but this width is determined by the usual "seat depth", i.e. the anatomical size of the hollow of the knees to the back of users.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein Kombinationsmöbel der eingangs genannten Art zu schaffen, welches nicht nur von einem Sitzmöbel (mit normaler Sitztiefe) in eine Doppelliege und umgekehrt verstellbar ist, sondern darüberhinaus auch in eine Einzelliege üblicher Breite verstellbar ist - jeweils auf einfache Weise, bei einfachem Aufbau.In contrast, the invention has for its object to provide a combination piece of furniture of the type mentioned, which is not only adjustable from a piece of seating (with normal seat depth) to a double bed and vice versa, but is also adjustable in a single bed of usual width - each in a simple manner Way, with simple construction.

Die Lösung dieser Aufgabe ist in dem Kennzeichnungsteil des Patentanspruchs 1 angegeben.The solution to this problem is specified in the characterizing part of claim 1.

Gemäß der Erfindung sind also zur schwenkbaren Verbindung zwischen Liege und Rückenliege zwei zusätzliche Kuppelstäbe vorgesehen, die mit zwei Bolzen an den Seitenholmen der Rückenliege/-lehne und mit ihren vorstehenden unteren Enden jeweils am Querholm der Sitzliege angebracht sind. Um die letzteren Bolzen herum ist die Rückenliege/-lehne von der Stellung als Rückenlehne (in welcher sie mit an sich üblichen Mitteln festgehalten bzw. abgestützt ist) in die horizontale Stellung als Liege - und umgekehrt - verschwenkbar. Wird nun nur eine einzige Liege benötigt, wobei das hochgeschwenkte Rückenteil stören würde, weil es zum einen einen Teil der Breite der Sitzliege wegnimmt und überhaupt unnütz und unschön in die Luft ragt, so braucht der Benutzer lediglich die unteren Bolzen der Rückenliege aus dem Eingriff mit den Kuppelstangen zu lösen; er kann nun die Rückenliege um die oberen Bolzen herum verschwenken und dabei gleichzeitig die Kuppelstäbe um ihre unteren Schwenkachsen gegenüber der Sitzliege nach vorn verschwenken, so daß die Rückenliege auf die Sitzliege zur Deckung gelangt die Rückenliege/-lehne dient nun also als normale Liege. Sehr von Vorteil ist dabei auch, daß das Rückenteil mit der Benutzungsfläche nach oben auf die Sitzliege gelangt, so daß man also auf der "Nutz-Seite" bzw. dem Polster der Rückenlehne liegt. Weiter ist von Vorteil, daß in der Einzelliege-Stellung die "Sitzliege" von der Rückenliege abgedeckt ist, also - besonders bei Verwendung als Gartenmöbel - vor Umwelteinflüssen, wie Sonne, Regen, geschützt ist.According to the invention, two additional coupling rods are thus provided for the pivotable connection between the bed and the back bed, which are attached with two bolts to the side rails of the back bed / backrest and with their projecting lower ends in each case on the cross member of the seat bed. Around the latter bolts, the backrest / backrest can be pivoted from the position as the backrest (in which it is held or supported by conventional means) to the horizontal position as the bed - and vice versa. If only a single bed is required, the swung-up back part would be annoying because it takes up part of the width of the seat bed and protrudes uselessly and ugly into the air, the user only needs the lower bolts of the back bed out of engagement loosen the coupling rods; he can now swivel the backrest around the upper bolts and at the same time swivel the coupling rods forward about their lower swivel axes with respect to the seat bed so that the back bed comes to cover the seat bed, the back bed / backrest now serves as a normal bed. It is also very advantageous that the back part with the usable surface comes up onto the seat bed, so that you are lying on the "useful side" or the upholstery of the backrest. Another advantage is that in the single recliner position the "seat bed" is covered by the back bed, so - especially when used as garden furniture - is protected against environmental influences such as sun, rain.

Weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Further refinements of the invention are specified in the subclaims.

Beim Verschwenken der Rückenliege werden Sitzliege und Rückenliege zweckmäßig gegenüber dem Traggestell verschoben. Gemäß der DE-PS-1 181 876 ist hierzu am Traggestell eine Führung angebracht, in der ein am Sitzteil angebrachter Gleitstein bzw. eine Rolle geführt ist.When the backrest is pivoted, the seatbed and backrest are expediently moved relative to the supporting frame. According to DE-PS-1 181 876, a guide is attached to the support frame in which a sliding block or a roller attached to the seat part is guided.

Zur weiteren Ausgestaltung der Erfindung ist diesbezüglich vorgesehen, daß die der Sitzliege zugehörenden Gelenkbolzen mit ihren vorstehenden Enden in je einer Nut geführt sind, die in je einer Querstrebe des Traggestells vorgesehen ist. Diese Gelenkbolzen dienen also gleichzeitig als Führungsmittel.For a further embodiment of the invention, it is provided in this regard that the hinge pins belonging to the seat bed are each guided with their projecting ends in a groove which is provided in a cross strut of the support frame. These hinge pins thus also serve as guide means.

Vorzugsweise ist die Nut leicht nach unten/vorne geneigt, um die Verschiebung in die Doppelliegestellung zu erleichtern und zu positionieren; am hinteren Ende der Nut ist eine Vertiefung vorgesehen, in welche der Gelenkbolzen jeweils in der hochgeschwenkten Sitzbank-Stellung der Rücken-Liege einrastet. Die hintere Kante der Sitz-Liege ist dabei zweckmäßig gegenüber dem Traggestell abgestützt; wenn man nämlich nun die Sitz-Liege an ihrer vorderen Kante hochhebt, so werden die Bolzen aus den Vertiefungen der beiden Nuten ausgehoben und man kann nun durch leichten Zug nach vorne die Sitz-Liege nebst der Rücken- Liege gegenüber dem Traggestell vorziehen (ihn die symmetrische Liegelage), dieser Bewegungsablauf wird durch das Gewicht der Rückenlehne unterstützt, die dabei gleichzeitig in die Horizontallage gelangt.The groove is preferably inclined slightly downwards / forwards in order to facilitate and position the movement into the double lying position; At the rear end of the groove, a recess is provided, into which the hinge pin engages in the swiveled-up seat position of the backrest. The rear edge of the seat bed is appropriately supported against the support frame; if you now lift the seat bed by its front edge, the bolts are lifted out of the recesses of the two grooves and you can now pull the seat bed and the back bed over the support frame by pulling it forward symmetrical lying position), this movement sequence is supported by the weight of the backrest, which at the same time reaches the horizontal position.

Bei der umgekehrten Verschiebung aus der Doppelliege-Lage in die Sitzbank-Stellung muß man nun allerdings gegen die Schwerkraft schieben. Um dies zu erleichtern, kann ein Federmechanismus vorgesehen sein, der beim Verschieben aus der Sitzbanklage in die Doppelliege-Lage gespannt wird; die so gespeicherte Federenergie erleichtert dann die Rückführung aus der Doppelliege-Lage in die Sitzbank-Stellung. Hierzu genügen beispielsweise zwei seitlich zwischen einem hinteren Teil des Traggestells und einem vorderen Teil der Sitzliege festgemachte Schrauben-Zugfedern (oder umgekehrt DruckFedern).In the reverse shift from the double bed position to the seat position, however, you now have to push against gravity. To facilitate this, a spring mechanism can be provided which Moving from the seat position to the double bed position is stretched; the spring energy stored in this way then facilitates the return from the double bed position to the seat position. For this purpose, for example, two helical tension springs (or vice versa compression springs) fixed laterally between a rear part of the support frame and a front part of the seat bed are sufficient.

Es könnte als zu umständlich angesehen werden, wenn der Benutzer erst umständlich die beiden unteren Bolzen der Rücken-Liege lösen müßte; es kann daher ein Mechanismus vorgesehen sein, mit welchem diese beiden Bolzen gleichzeitig durch einen einzigen Handgriff aus ihrem Eingriff mit dem jeweiligen Kuppelstab gelöst werden. Ein solcher Mechanismus ist in den Unteransprüchen 7 und 8 angegeben und in der Figurenbeschreibung weiter im einzelnen erläutert.It could be considered too cumbersome if the user had to laboriously loosen the two lower bolts of the back couch; a mechanism can therefore be provided with which these two bolts are released from their engagement with the respective coupling rod at the same time by a single handle. Such a mechanism is specified in subclaims 7 and 8 and further explained in detail in the description of the figures.

In weiterer Ausbildung sind beide Liegen als sogen. Gesundheitsliegen ausgebildet, also bestehend aus je einem Rahmen auf bzw. in dem ein Lattenrost vorgesehen ist, wobei ein mittlerer Teil, Sitzteil, des Lattenrostes fest auf dem Rahmen festgemacht ist, während demgegenüber ein Fußteil und ein Rückenteil in die jeweils gewünschte Neigung schwenkbar sind.In further training, both couches are so-called. Health couches formed, i.e. each consisting of a frame on or in which a slatted frame is provided, with a central part, seat part, of the slatted frame being firmly attached to the frame, while, in contrast, a foot part and a back part can be pivoted into the desired inclination.

Auf einem auf Rädern 50 verfahrbaren Traggestell 3 sind in Längsrichtung bzw. Fahrtrichtung zwei an sich gleiche Liegen 1, 2 angeordnet, von denen die eine als Sitz-Liege 1 und die andere als Rücken-Liege 2 bezeichnet sei. In Fig. 1 sind Sitz-Liege 1 und Rücken-Liege 2 horizontal nebeneinander und symetrisch zum Traggestell 3 vorgesehen. Die Liegen 1, 2 haben etwa die gleiche Breite wie das Traggestell 3, in der Doppelliege-Stellung nach Fig. 1 ragen sie also jeweils mit knapp ihrer halben Breite über das Traggestell 3 hinaus. An ihren beiden endständigen Querholmen 9, 10 sind die beiden Liegen 1, 2 mit jeweils einem, also insgesamt zwei Kuppelstäben 11, 12 miteinander verbunden.On a support frame 3 which is movable on wheels 50, two couches 1, 2, which are identical per se, are arranged in the longitudinal direction or travel direction, one of which is referred to as a seat couch 1 and the other as a back couch 2. In Fig. 1, the seat couch 1 and back couch 2 are provided horizontally next to each other and symmetrically to the support frame 3. The couches 1, 2 have approximately the same width as the support frame 3, so in the double bed position according to FIG. 1, they each project with almost half the width beyond the support frame 3. The two couches 1, 2 are connected to one another, that is to say a total of two coupling rods 11, 12, at their two terminal cross bars 9, 10.

Dank dieser Verbindung sind die beiden Liegen gegenüber dem Traggestell 3 verschieblich und die Rücken-Liege 2 ist gegenüber der Sitz-Liege 1 auf besondere Weise auf- und nieder schwenkbar in eine Sitzbankstellung nach Fig.4; außerdem ist die Rücken-Liege noch so verschwenkbar, daß sie - zur Verwendung als Einzel-Liege - mit ihrer Oberseite/Gebrauchseite nach oben deckungsgleich auf die Sitz-Liege bzw. das Traggestell gelangt.Thanks to this connection, the two loungers are displaceable relative to the support frame 3 and the back lounger 2 can be pivoted up and down in a special way relative to the seat lounger 1 into a seat position according to FIG. 4; in addition, the back bed is still pivotable so that - for use as a single bed - it is congruent with the top / use side up on the seat bed or the support frame.

Und zwar ist jeder Kuppelstab 11, 12 an seinem einen Ende mit einem (horizontal in Fahrtrichtung weisenden) Gelenkbolzen 13, 14 am Querholm 9 der Sitz-Liege 1 angelenkt und mit zwei Bolzen 15,16; 17, 18 am Querholm 10 der Rücken-Liege 2 festgemacht. Die Rücken-Liege 2 kann also als Rückenlehne hochgeschwenkt werden (Fig. 4). Die Gelenk-Bohrung an der Sitzliege 1 ist dabei um einen Abstand a vorverlegt derart, daß sich gerade die anatomisch richtige Sitztiefe b ergibt, obwohl die Sitz-Liege wie die Rücken-Liege eine größere (untereinander gleiche) Breite c haben, die für ein bequemes Liegen erforderlich ist. In der Sitzbank-Stellung kommt die Unterkante 4 der Rücken-Liege 2 über das Polster 36 der Sitz- Liege 1 in Stellung, dabei steht die gesamte Breite der Rücken-Liege 2 zur Bildung einer hohen, bequemen Rückenlehen zur Verfügung.Namely, each coupling rod 11, 12 is articulated at one end with a (horizontally pointing in the direction of travel) hinge pin 13, 14 on the cross member 9 of the seat couch 1 and with two bolts 15, 16; 17, 18 attached to the cross member 10 of the back-couch 2. The back bed 2 can thus be pivoted up as a backrest (Fig. 4). The articulated hole on the seat bed 1 is moved forward by a distance a such that the anatomically correct seat depth b is obtained, although the seat bed like the back bed has a larger (mutually identical) width c that is suitable for a comfortable lying is required. In the seat position, the lower edge 4 of the backrest 2 comes into position via the cushion 36 of the seatrest 1, the entire width of the backrest 2 being available for forming a high, comfortable backrest.

Allerdings muß die Rücken-Liege 2 nicht nur hochgeschwenkt werden, sondern gleichzeitig müssen Sitz-Liege 1 und Rücken-Liege 2 gegenüber dem Traggestell 3 nach hinten verschoben werden (von Fig. 1 nach Fig. 4). Zu diesem Zweck stehen die Gelenkbolzen 13, 14 über die Kuppelstäbe 11, 12 vor und diese vorstehenden Enden 13a, 14a sind in je einer Nut 21, 22 an einem horizontalen Querholm 19, 20 des Traggestells 3 geführt.However, the back bed 2 not only has to be swung up, but at the same time the seat bed 1 and back bed 2 have to be moved backwards relative to the supporting frame 3 (from FIG. 1 to FIG. 4). For this purpose, the hinge pins 13, 14 project beyond the coupling rods 11, 12 and these projecting ends 13a, 14a are each guided in a groove 21, 22 on a horizontal cross member 19, 20 of the support frame 3.

(Siehe besonders Figuren 4 und 5) Die Nut 21, 22 ist leicht nach vorn geneigt. Das vordere Ende der Nut 21, 22 begrenzt den Verschiebeweg nach vorn in die Doppelliege-Stellung. Am hinteren Ende der Nut ist eine Vertiefung 23, 24 in die die Gelenkbolzenenden 13a, 14a in der Sitzbank- Stellung (Fig. 4) einrasten, womit die Liegen (nun das Sitzteil und die Rückenlehne der Sitzbank) richtig gegenüber dem Traggestell 3 positioniert sind.(See especially Figures 4 and 5) The groove 21, 22 is slightly inclined forward. The front end of the groove 21, 22 limits the forward displacement into the double bed position. At the rear end of the groove there is a recess 23, 24 into which the pivot pin ends 13a, 14a engage in the seat position (FIG. 4), with the result that the couches (now the seat part and the backrest of the seat) are correctly positioned relative to the support frame 3 .

An der Rücken-Liege 2 greift beidseits je ein Seil 25, 26 mit Öse an, die Öse kann an jeweils einen einer Reihe von Stiften 29 angehängt werden, die an einem oberen Querholm 27, 28 des Traggestells 3 vorgesehen sind, so daß die Rücken-Liege/Lehne in ihrer Schräglage einstellbar ist. Will man das Möbel aus der Sitzbank-Stellung (Fig. 4) wieder verstellen in die Doppelliege-Stellung (Fig. 1) so braucht man die Sitz-Liege nur an ihrem vorderen Längsholm hochzuschwenken (Pfeil 40 in Fig. 5), bis der Gelenkbolzen 13, 14 aus der Vertiefung 23, 24 herausgelangt. Durch leichten Zug nach vorn gleiten nun Sitz-Liege und Rücken-Liege 2 in die Stellung nach Fig. 1, wobei die Gelenkbolzen in der geneigten Nut 21, 22 geführt sind; die Rücken-Liege verschwenkt sich dabei gleichzeitig in die Horizontal-Lage. Dabei ist vorgesehen, daß sich die Sitz-Liege mit ihrer unteren hinteren Kante auf dem Traggestell 3 abstützt, womit der erforderliche Drehpunkt gegeben ist. Durch das Gewicht der Rücken- Liege wird dieser Bewegungsablauf unterstützt. Bei einer bestimmten, bevorzugten Neigung der Rückenlehne bleibt dabei der Abstand zum Aufhängepunkt gleich, so daß die Halteseile 25, 26 nicht gelöst zu werden brauchen.On the back bed 2, a rope 25, 26 engages on both sides with an eyelet, the eyelet can be attached to one of a series of pins 29, which are provided on an upper cross member 27, 28 of the support frame 3, so that the back -Lay / backrest is adjustable in its inclined position. If you want to move the furniture from the seat position (Fig. 4) to the double bed position (Fig. 1) you need that Swing up the seat-couch only on its front longitudinal spar (arrow 40 in FIG. 5) until the hinge pin 13, 14 comes out of the recess 23, 24. With a slight pull forward, the seat bed and back bed 2 slide into the position shown in FIG. 1, the hinge pins being guided in the inclined groove 21, 22; the back bed swivels into the horizontal position at the same time. It is provided that the seat bed is supported with its lower rear edge on the support frame 3, which provides the required pivot point. This movement is supported by the weight of the back bed. With a certain, preferred inclination of the backrest, the distance to the suspension point remains the same, so that the tethers 25, 26 do not have to be released.

Beim Zurück/Hochschieben aus der Doppelliege-Stellung (Fig. 1) in die Sitzbank- Stellung (Fig. 4) muß man allerdings gegen die Schwerkraft arbeiten, um dies zu erleichtern kann ein Federmechanismus vorgesehen sein (s. Anspruch 6), der unterschiedlich ausgebildet sein kann und der besseren Übersichtlichkeit halber nicht gezeigt ist.When pushing back / up from the double bed position (Fig. 1) into the seat position (Fig. 4), however, one has to work against gravity, in order to facilitate this, a spring mechanism can be provided (see claim 6), which is different can be formed and is not shown for the sake of clarity.

Das Möbel kann insb. auch als Einzelliege nach Fig. 6 verwendet werden. Die Rückenliege liegt hierbei mit ihrer Gebrauchsseite 8 nach oben.The furniture can in particular also be used as an individual bed according to FIG. 6. The backrest lies with its use side 8 upwards.

Zu diesem Zweck ist jeweils der untere Bolzen 15,17 der Rücken-Liege 2 aus dem Eingriff mit dem Kuppelstab 11, 12 zurückziehbar, so daß die Rücken-Liege 2 um den oberen Bolzen 16, 18 verschwenkbar ist, während gleichzeitig der Kuppelstab 11, 12 (und damit die Rücken-Liege 2) um den Gelenkbolzen 13, 14 herum gegenüber der Sitz-Liege 1 verschwenkbar ist.For this purpose, the lower bolt 15, 17 of the back bed 2 can be withdrawn from engagement with the coupling rod 11, 12, so that the back bed 2 can be pivoted about the upper bolt 16, 18, while at the same time the coupling rod 11, 12 (and thus the back bed 2) can be pivoted around the hinge pin 13, 14 relative to the seat bed 1.

Mittels des Mechanismus nach Fig. 7 und 8 können die beiden unteren Bolzen durch einen einzigen Handgriff gleichzeitig gelöst werden.By means of the mechanism according to FIGS. 7 and 8, the two lower bolts can be loosened simultaneously by a single handle.

Und zwar ist jeweils mittels einer Schraube 41 ein zweiarmiger Hebel 42 am Querholm 31 der Liege angebracht. Gegen den einen Hebelarm 42 wirkt eine Feder 43, am anderen Hebelarm 44 greift ein Zugseil 45 an, zwischen Zugseil und Schraube ist der Bolzen 15, 17 entsprechend beweglich am Hebel angebracht. Die Druckfeder 43 hält also den Bolzen in Eingriffsstellung in dem Kuppelstab 11, 12, mittels Zugseil 45 können beide Bolzen 15, 17 - gegen die Kraft der Feder - gelöst werden. Das für beide Bolzen gemeinsame Zugseil 45 ist in Fig. 7 zum oberen Längsholm 32 der Rücken-Liege 2 und durch diesen hindurch geführt, so daß es oben ergriffen werden kann. Der Benutzer braucht sich also bei der Betätigung nicht zu bücken Einfacher ist die Seilführung aber, wenn das Zugseil zum unteren Längsholm 33 geführt wird.Namely, a two-armed lever 42 is attached to the cross member 31 of the bed by means of a screw 41. A spring 43 acts against one lever arm 42, a pulling cable 45 acts on the other lever arm 44, and between the pulling cable and screw the bolt 15, 17 is correspondingly movably attached to the lever. The compression spring 43 thus holds the bolt in the engaged position in the coupling rod 11, 12, both bolts 15, 17 - against the force of the spring - can be released by means of a pulling cable 45. The common pull cable 45 for both bolts is in Fig. 7 to the upper longitudinal spar 32 of the back couch 2 and through it, so that it can be gripped at the top. The user therefore does not have to bend over when actuating, but the rope guide is simpler if the pull rope is guided to the lower longitudinal spar 33.

Wie aus Figuren 2 und 3 ersichtlich, sind die beiden Liegen mit hochschwenkbarem Fußteil 46 und Rückenteil 47, als sogen. Gesundheitsliegen ausgebildet. Zu diesem Zweck weist jede Liege einen rechteckigen Rahmen 30 auf, an dessen mittlerem Bereich ein Gesäßteil 49 fest angebracht ist. An dem Gesäßteil 49 sind einerseits das Fußteil 46 und andererseits das Rückenteil 47 angelenkt (Gelenke 48). Mittels einer einstellbaren Stütze 51 ist die Neigung verstellbar.As can be seen from Figures 2 and 3, the two couches with a swiveling foot part 46 and back part 47, as so-called. Health beds trained. For this purpose, each bed has a rectangular frame 30, on the central area of which a seat part 49 is firmly attached. The foot part 46 and the back part 47 are articulated on the seat part 49 on the one hand (joints 48). The inclination can be adjusted by means of an adjustable support 51.

Bisher besteht die Gefahr des Einquetschens der Finger, wenn ein Benutzer auf dem Mittelteil, Gesäßteil 49 sitzend das Rückenteil 47 verstellen will. Diese Gefahr wird dadurch beseitigt, daß am jeweils oberen Ende beidseits zwei Stützstäbe 52 angelenkt sind, die also frei nach unten hängen und sich in einer kleinsten Schräglage des Rückenteils an dem Rahmen 30 der Liege abstützen. Diese kleinste Neigung ist immer noch so groß, daß die Finger einer den Rückenteil 47 untergreifenden Hand immer noch zwischen Rückenteil und Rahmen Platz haben, also nicht geklemmt werden können. Das Fußteil 46 ist ebenso ausgebildet wie das Rückenteil 47. Zwischen beiden Liegen kann ein Spalt vorgesehen sein (indem die Liegen etwas schmaler sind), so daß man zum Verschwenken des Rückenteils zwischengreifen kann.So far there is a risk of fingers being squeezed if a user wants to adjust the back part 47 while sitting on the middle part, buttock part 49. This danger is eliminated by the fact that two support rods 52 are articulated on both sides of the upper end, which thus hang freely downward and are supported on the frame 30 of the bed in the smallest inclined position of the back part. This smallest inclination is still so great that the fingers of a hand under the back part 47 still have space between the back part and the frame, that is to say they cannot be clamped. The foot part 46 is designed in the same way as the back part 47. A gap can be provided between the two beds (in that the beds are somewhat narrower), so that one can intervene to pivot the back part.
