Description

Die Erfindung betrifft ein Polstermöbel mit einer Anzahl von Polstermöbel, die miteinander verbunden, gegeneinander verstellbar, walzenförmig ausgebildet, als Schlange unmittelbar aneinandergereiht und auf Trägern gelagert sind, wobei die Träger der zwischen dem ersten und letzten Polsterelement der Schlange angeordneten Polsterelemente an beiden Enden mit jeweils einem selbsthemmenden Beschlag mit zwei gegeneinander verstellbaren Beschlagteilen gekoppelt sind, die jeweils mit einem Beschlagteil der den beiden benachbarten Polsterelementen zugeordneten Beschläge verbunden sind.The invention relates to upholstered furniture with a number of upholstered furniture which are connected to one another, adjustable with respect to one another, roller-shaped, arranged directly in a row as a snake and are mounted on supports, the supports of the upholstered elements arranged between the first and last upholstery elements of the snake having at each end a self-locking fitting is coupled to two mutually adjustable fitting parts, each of which is connected to a fitting part of the fittings assigned to the two adjacent upholstery elements.

Ein derartiges Polstermöbel ist aus der FR-A-2 196 134 bekannt. Bei diesem bekannten Polstermöbel sind die Polstermöbel auf Trägern angeordnet, wobei die Träger der zwischen dem ersten und letzten Polsterelement der Schlange angeordneten Polsterelemente an beiden Enden mit jeweils einem selbsthemmenden Beschlag mit zwei gegeneinander verstellbaren Beschlagteilen gekoppelt ist. Die beiden Beschlagteile eines Beschlages sind jeweils mit einem Beschlagteil der den beiden benachbarten Polsterelementen zugeordneten Beschläge verbunden.Such upholstered furniture is known from FR-A-2 196 134. In this known upholstered furniture, the upholstered furniture is arranged on supports, the support of the upholstered elements arranged between the first and last upholstery element of the snake being coupled at both ends with a self-locking fitting with two mutually adjustable fitting parts. The two fitting parts of a fitting are each connected to a fitting part of the fittings assigned to the two adjacent upholstery elements.

Es ist Aufgabe der Erfindung, ein Polstermöbel der eingangs erwähnten Art zu schaffen, bei dem der Aufwand für das Gestell reduziert ist und die Polsterelemente gegeneinander in grösserem Winkelbereich zueinander verstellt werden können.It is an object of the invention to provide upholstered furniture of the type mentioned in the introduction, in which the effort for the frame is reduced and the upholstery elements can be adjusted relative to one another in a larger angular range.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die Polsterelemente auf Lagerwellen angeordnet sind, dass die Lagerwellen der zwischen dem ersten und letzten Polsterelement der Schlange angeordneten Polsterelemente an beiden Enden jeweils mit dem selbsthemmenden Beschlag gekoppelt sind, dass eines der Beschlagteile mittels eines Exzenters gegenüber dem anderen Beschlagteil verstellbar ist und dass die beiden Beschlagteile des Beschlages jeweils mit einem Beschlagteil der den beiden benachbarten Polsterelementen zugeordneten Beschläge zu einstückigen Verbindungslaschen zusammengefasst sind.This object is achieved according to the invention in that the cushion elements are arranged on bearing shafts, that the bearing shafts of the cushion elements arranged between the first and last cushion elements of the snake are each coupled at both ends to the self-locking fitting, that one of the fitting parts is opposed by means of an eccentric the other fitting part is adjustable and that the two fitting parts of the fitting are combined with a fitting part of the fittings assigned to the two adjacent upholstery elements to form one-piece connecting straps.

Diese Aufgabe wird ferner durch die kennzeichnenden Merkmale des Anspruches 11 gelöst.This object is further achieved by the characterizing features of claim 11.

Die Polsterelemente bilden eine Schlange bei der die Polsterelemente über die Verbindungslaschen direkt miteinander gekoppelt sind und im Bereich ihrer Mittellängsachse die Drehachse für die Beschläge haben. Daher können die benachbarten Polsterelemente über einen grossen Winkelbereich gegeneinander verstellt werden, der weit grösser ist als 180°. Die Polsterelemente lassen sich zudem in eine sehr raumsparende Ablagestellung einstellen.The upholstery elements form a snake in which the upholstery elements are directly coupled to one another via the connecting straps and have the axis of rotation for the fittings in the region of their central longitudinal axis. Therefore, the neighboring upholstery elements can be adjusted against each other over a large angular range that is far greater than 180 °. The upholstery elements can also be placed in a very space-saving storage position.

Nach der Ausgestaltung ist vorgesehen, dass die Polsterelemente zentrisch eine durchgehende Lagerhülse aufweisen, in der die zugeordnete Lagerwelle frei drehbar gelagert ist. Unabhängig von der Einstellung der Schlange können sich die Polsterelemente dann frei auf ihren Lagerwellen drehen.According to the embodiment, it is provided that the cushion elements have a continuous bearing sleeve in the center, in which the associated bearing shaft is freely rotatable. Regardless of the snake setting, the cushion elements can then rotate freely on their bearing shafts.

Für die selbsthemmenden Beschläge kann auf Beschläge zurückgegriffen werden, wie sie z.B. für die Verstellung der Rückenlehne eines Kraftfahrzeugsitzes in Verwendung und so ausgestaltet sind, dass die Beschlagteile als ineinander greifendes, aus der Verbindungslasche ausgeprägtes Zahnrad und als aus der Verbindungslasche ausgeprägte Innenzahnkranzaufnahme ausgebildet sind, wobei der Durchmesser des Zahnrades um eine Exzentrizität kleiner ist als der Durchmesser der Innenzahnkranzaufnahme, dass die Innenzahnkranzaufnahme zentrisch zur Lagerwelle angeordnet ist, dass das Zahnrad mittels des durch die Lagerwelle betätigten Exzenters in der Innenzahnkranzaufnahme verschiebbar und verdrehbar ist und dass die Innenzahnkranzaufnahme mit der Lagerwelle drehfest gekoppelt ist.For the self-locking fittings, fittings can be used, e.g. are used for the adjustment of the backrest of a motor vehicle seat and are designed such that the fitting parts are designed as an intermeshing gearwheel formed from the connecting lug and an internal toothed ring receptacle shaped from the connecting lug, the diameter of the gearwheel being smaller by an eccentricity than the diameter of the Internal gear rim receptacle, that the inner gear rim receptacle is arranged centrally to the bearing shaft, that the gear wheel can be displaced and rotated in the inner gear rim receptacle by means of the eccentric actuated by the bearing shaft, and that the inner gear rim receptacle is rotatably coupled to the bearing shaft.

Die Kopplung der Beschläge mit der zugeordneten Lagerwelle wird dabei dadurch hergestellt, dass die Enden der Lagerwelle in Lagerkörpern eines Beschlaggehäuses unverdrehbar gehalten sind und dass diese Lagerkörper in der die Innenzahnkranzaufnahme bildenden Ausprägung des jeweils ersten Beschlagteiles der ersten Verbindungslasche drehbar gelagert sind und die Exzenter tragen, die in der das Zahnrad bildenden Ausprägung des jeweils zweiten Beschlagteiles der zweiten Verbindungslasche des Beschlages drehbar gelagert sind. Die unverdrehbare Festlegung wird dabei dadurch erreicht, dass die Enden der Lagerwellen als im Querschnitt quadratische Mitnehmer ausgebildet sind, die in entsprechende Aufnahmen der Lagerkörper unverdrehbar eingesteckt sind.The coupling of the fittings to the associated bearing shaft is produced in such a way that the ends of the bearing shaft are held in a non-rotatable manner in the bearing bodies of a fitting housing and that these bearing bodies are rotatably mounted in the design of the respective first fitting part of the first connecting bracket that forms the inner toothed ring receptacle and carry the eccentrics, which are rotatably mounted in the form of the gearwheel of the respective second fitting part of the second connecting bracket of the fitting. The non-rotatable fixing is achieved in that the ends of the bearing shafts are designed as drivers with a square cross section, which are inserted non-rotatably into corresponding receptacles of the bearing bodies.

Ist es vorgesehen, dass ein oder beide Lagerkörper einer Lagerwelle mit einem Handrad unverdrehbar verbunden ist (sind), dann kann die Verstellung an einer oder beiden Seiten der Schlange vorgenommen werden.If it is provided that one or both bearing bodies of a bearing shaft are (are) non-rotatably connected to a handwheel, then the adjustment can be carried out on one or both sides of the coil.

Ist es vorgesehen, dass die Beschlagteile der Beschläge um 360° gegeneinander verschwenkbar sind, dann ist das Optimum an Einstellmöglichkeiten gegeben.If it is provided that the fitting parts of the fittings can be pivoted through 360 ° relative to one another, then the optimum setting options are provided.

Für die Anbringung des ersten und letzten Polsterelementes an der Schlange sieht eine Ausgestaltung vor, dass die zum ersten und letzten Polsterelement der Reihe führenden Verbindungslaschen in einfache Lagerflansche mit Lagerbohrungen für eine durchgehende Lagerwelle auslaufen.For the attachment of the first and last cushion element to the snake, one embodiment provides that the connecting straps leading to the first and last cushion element in the row end in simple bearing flanges with bearing bores for a continuous bearing shaft.

Eine einfache alternative Ausgestaltung der Erfindung ist im Anspruch 11 angegeben. Dabei sind die zwei Beschlagteile als Lochscheiben ausgebildet, die auf einem gleichen Durchmesser eine Reihe von Bohrungen aufweisen. In eine oder mehrere von fluchtenden Bohrungen der beiden den Beschlag bildenden Lochscheiben sind Arretierungsbolzen einführbar und darin festlegbar. Diese Beschläge erlauben nur eine stufige Einstellung in grösseren Winkelbereichen. Der Teile- und Montageaufwand ist aber wesentlich geringer und das Polstermöbel kann zerlegt gelagert und geliefert und von jedem Laien am Einsatzort zusammengebaut werden.A simple alternative embodiment of the invention is specified in claim 11. The two fitting parts are designed as perforated disks which have a number of bores on the same diameter. Locking bolts can be inserted and fixed in one or more of the aligned bores of the two perforated disks forming the fitting. These fittings only allow a stepped adjustment in larger angular ranges. The parts and assembly effort is much lower and the upholstered furniture can be stored and delivered disassembled and assembled by any layperson on site.

Die Arretierung der Beschläge wird nach einerAusgestaltung dabei in einfacher Weise dadurch erreicht, dass die Arretierungsbolzen an einer mit zentrischer Bohrung versehenen Scheibe in gleicher Winkelteilung zueinander angebracht sind, die mittels einer Schraubverbindung mit der Lagerwelle des Polsterelementes verbindbar ist. Die Schraubverbindung ist nach einer weiteren Ausgestaltung so ausgeführt, dass in die Enden der als Hohlwelle ausgebildeten Lagerwelle unverdrehbar und unverschiebbar Muttern eingebracht sind, in die eine mit einem Gewindeteil und einem Griffteil versehene Arretierungsplatte einschraubbar ist, wobei die Arretierungsplatte die mit den Arretierungsbolzen versehene Scheibe gegen die beiden mit Durchgangsbohrungen versehenen, als Lochscheiben ausgebildeten Beschlagteile und die Stirnseite der Lagerwelle verspannt.According to one embodiment, the locking of the fittings is achieved in a simple manner in that the locking bolts are attached to a disc provided with a central bore in the same angular pitch, which can be connected to the bearing shaft of the cushion element by means of a screw connection. According to a further embodiment, the screw connection is designed in such a way that in the ends it is designed as a hollow shaft The bearing shaft cannot be rotated and cannot be displaced, and nuts into which a locking plate provided with a threaded part and a handle part can be screwed, the locking plate bracing the disk provided with the locking bolt against the two fitting parts provided as through-holes, designed as perforated disks, and bracing the end face of the bearing shaft.

Ist es nach einer weiteren Ausgestaltung vorgesehen, dass an einer Verbindungslasche die beiden als Beschlagteile ausgebildeten Lochscheiben eine unterschiedliche Anzahl von Bohrungen aufweisen, dass die Scheiben eine Anzahl von Arretierungsbolzen aufweisen, dass die Anzahl der Bohrungen in den beiden Lochscheiben durch die Anzahl der Arretierungszapfen teilbar ist und dass die Bohrungen in den beiden Lochscheiben jeweils in gleichmässiger, aber unterschiedlicher Winkeleinteilung eingebracht sind, dann werden nur einheitlich ausgebildete Laschen benötigt, die nicht einmal abgekröpft werden müssen, da es im Bereich eines Beschlages egal ist, wie die beiden Lochscheiben im Bezug auf das Polsterelement angeordnet sind. Durch die unterschiedliche und auf die Anzahl der Arretierungsbolzen abgestimmte Auslegung der Lochscheiben wird erreicht, dass schon mit einer kleinen Anzahl von Bohrungen in den Lochscheiben die Verstellung in kleinen Winkelbereichen erfolgen kann.According to a further embodiment, it is provided that the two perforated disks designed as fitting parts have a different number of bores on a connecting bracket, that the disks have a number of locking bolts, that the number of bores in the two perforated disks can be divided by the number of locking pins and that the holes in the two perforated disks are each made in a uniform but different angle, then only uniformly designed brackets are required, which do not even have to be bent, since it does not matter in the area of a fitting how the two perforated disks relate to the Upholstery element are arranged. The different design of the perforated disks, which is matched to the number of locking bolts, means that the adjustment can be carried out in small angular ranges even with a small number of holes in the perforated disks.

Mit den als Lochscheiben ausgebildeten Beschlagteilen ergibt sich nach einer Ausgestaltung dadurch eine weitere Erweiterungsmöglichkeit, dass zwischen der Arretierungsplatte und der mit den Arretierungsbolzen versehenen Scheibe ein weiteres mit einer Bohrung für das Gewindeteil der Arretierungsplatte versehenes Beschlagteil angeordnet und festgespannt ist. So kann dieses weitere Beschlagteil z.B. als Fuss ausgebildet sein, so dass das Polstermöbel von der Standfläche abgesetzt werden kann. Ist es nach einer Ausgestaltung vorgesehen, dass die Verbindungslasche abgewinkelt ist, so dass die Ebenen der beiden Beschlagteile in einem vorgegebenen Winkel zueinander stehen, dann können an die schlangenförmig verbundenen Polsterelemente weitere Polsterelemente in dem vorgegebenen Winkel eingebracht werden.With the fitting parts designed as perforated disks, according to one embodiment, there is a further possibility of expansion that a further fitting part with a bore for the threaded part of the locking plate is arranged and clamped between the locking plate and the washer provided with the locking bolt. This additional fitting part can e.g. be designed as a foot so that the upholstered furniture can be set down from the base. If it is provided according to one embodiment that the connecting bracket is angled so that the planes of the two fitting parts are at a predetermined angle to one another, then further cushioning elements can be introduced at the predetermined angle to the serpentine-connected cushion elements.

Die Seitenansicht nach Fig. 1 zeigt zwölf walzenförmige Polsterelemente 10, die unmittelbar aneinandergereiht sind und eine Schlange bilden. Die Verbindungslaschen 30 halten die Polsterelemente 10 auf Abstand. Die Polsterelemente 10 sind zentrisch auf Lagerwellen gelagert, die an beiden Enden mit sogenannten selbsthemmenden Beschlägen 20 gekoppelt sind. Die beiden gegeneinander verstellbaren Beschlagteile des Beschlages 20 sind durch Verdrehen der Lagerwelle in jede beliebige Stellung zueinander verstellbar, wenn sie gegeneinander um 360° verschwenkbar sind. Die Verbindungslaschen 30 sind mit den Beschlagteilen benachbarter Polsterelemente 10, d.h. benachbarter Beschläge 20, verbunden. Lediglich an dem ersten und letzten Polsterelement 10 der Schlange sind keine Beschläge vorgesehen, da es genügt, diese Polsterelemente 10 über ihre Lagerwellen an den Verbindungslaschen 30 zu lagern.The side view of FIG. 1 shows twelve roller-shaped cushion elements 10 which are lined up directly and form a snake. The connecting straps 30 keep the cushion elements 10 at a distance. The cushion elements 10 are mounted centrally on bearing shafts, which are coupled at both ends with so-called self-locking fittings 20. The two mutually adjustable fitting parts of the fitting 20 can be adjusted to each other by rotating the bearing shaft in any position if they can be pivoted against each other by 360 °. The connecting straps 30 are connected to the fitting parts of adjacent cushion elements 10, i.e. adjacent fittings 20, connected. Only fittings are provided on the first and last cushion element 10 of the snake, since it is sufficient to mount these cushion elements 10 on the connecting straps 30 via their bearing shafts.

Sind die ersten und letzten Polsterelemente 10 über ihre vertikal gestellten Verbindungslaschen als Fusselemente an den übrigen, mit den horizontal eingestellten Verbindungslaschen 30, horizontal ausgerichteten Polsterelementen 10 abgewinkelt, dann bildet das Polsterelement die Liege nach Fig. 1.If the first and last upholstery elements 10 are angled via their vertically positioned connecting straps as foot elements on the other, horizontally aligned upholstery elements 10 with the horizontally adjusted connecting straps 30, then the upholstery element forms the bed according to FIG. 1.

Wie in Fig. 2 angedeutet ist, können die zwischen dem ersten und letzten Polsterelement 10 der Schlange liegenden Polsterelemente so eingestellt werden, dass die Liege eine anatomisch angepasste Liegefläche mit Liegemulde und erhöhtem Kopfteil aufweist.As indicated in FIG. 2, the cushion elements lying between the first and last cushion element 10 of the snake can be adjusted in such a way that the couch has an anatomically adapted lying surface with a lying depression and a raised head part.

Die Fig. 3 und 4zeigen schematisch die Einstellung der Schlange als Sessel, wobei bei dem Ausführungsbeispiel nach Fig. 3 das Fussteil hochgestellt ist und bei dem Ausführungsbeispiel nach Fig. 4 das Rückenteil nach Art eines Strandkorbes mit einem Baldachin abgeschlossen ist.3 and 4 show schematically the setting of the snake as an armchair, wherein in the embodiment according to FIG. 3 the foot part is raised and in the embodiment according to FIG. 4 the back part is closed with a canopy in the manner of a beach chair.

In Fig. 5 sind die wesentlichsten Teile eines handelsüblichen Beschlages gezeigt, wobei die komplementären Beschlagteile 31 und 34 zu Verbindungslaschen 30 ergänzt sind.5 shows the most important parts of a commercially available fitting, the complementary fitting parts 31 and 34 being supplemented to form connecting straps 30.

Von den durch die Polsterelemente 10 geführten Lagerwellen 40 sind die als Mitnehmer 47 ausgebildeten Enden gezeigt. Das dem Ende der Lagerwelle 40 zugekehrte Beschlagteil 34 ist als ausgeprägte Innenzahnkranzaufnahme ausgebildet die dem Ende der Lagerwelle 40 abgekehrt ist. In diese Innenzahnkranzaufnahme greift das an der anderen Verbindungslasche 30 des Beschlages ausgeprägte Zahnrad als komlementäres Beschlagteil 31 ein. Die Lagerwelle 40 ist dabei mit dem Mitnehmer 47 in eine entsprechende stirnseitige Aufnahme des Lagerkörpers 41 unverdrehbar eingesteckt. Der Lagerkörper 41 ist mit dem Lagerbund 42 in der Lagerbohrung 35 des Beschlagteiles 34 drehbar gelagert. Der Lagerkörper 41 weist einen Exzenter 43 auf, der in der Lagerbohrung 33 des komplementären Beschlagteiles 31 drehbar gelagert ist. Der Durchmesser des ausgeprägten Zahnrades ist um die Exzentrizität des Exzenters 43 kleiner als der Durchmesser der Innenzahnkranzaufnahme, so dass das Zahnrad durch Verdrehen des Exzenters 43 und damit des Lagerkörpers 41 und der Lagerwelle 40 in der Innenzahnkranzaufnahme verschoben und verdreht werden kann, wobei durch die Zahnteilung die Stufen der Schwenkbewegung zwischen den beiden Beschlagteilen 31 und 34 und damit der benachbarten Polsterelemente 10 bestimmt ist.The ends of the bearing shafts 40 guided through the cushion elements 10 are shown as drivers 47. The fitting part 34 facing the end of the bearing shaft 40 is designed as a pronounced internal ring gear seat which faces away from the end of the bearing shaft 40. The toothed wheel, which is pronounced on the other connecting lug 30 of the fitting, engages in this internal toothed ring receptacle as a complementary fitting part 31. The bearing shaft 40 is inserted with the driver 47 in a corresponding end receptacle of the bearing body 41 non-rotatably. The bearing body 41 is rotatably mounted with the bearing collar 42 in the bearing bore 35 of the fitting part 34. The bearing body 41 has an eccentric 43 which is rotatably mounted in the bearing bore 33 of the complementary fitting part 31. The diameter of the pronounced gearwheel is smaller by the eccentricity of the eccentric 43 than the diameter of the internal toothed ring receptacle, so that the gearwheel by turning the eccentric 43 and thus the bearing body pers 41 and the bearing shaft 40 in the inner ring gear receptacle can be shifted and rotated, the stages of the pivoting movement between the two fitting parts 31 and 34 and thus the adjacent cushion elements 10 being determined by the tooth pitch.

Die in der Bohrung 37 gelagerte Laufrolle 38 hält die beiden Verbindungslaschen 30 eines Beschlages 20 aneinander, lässt aber deren Verdrehung um die Lagerwelle 40 zu. Die Bohrungen 39 dienen zur Befestigung des Beschlaggehäuses 44, in dem auch der Lagerkörper 41 gelagert ist, wie in Fig. 6 zu sehen ist. Der Lagerkörper kann mit einem Anschlusselement 48 aus dem Beschlaggehäuse 44 ragen und zur unverdrehbaren Festlegung eines Handrades 45 dienen.The roller 38 mounted in the bore 37 holds the two connecting lugs 30 of a fitting 20 together, but allows them to be rotated about the bearing shaft 40. The bores 39 serve to fasten the fitting housing 44, in which the bearing body 41 is also mounted, as can be seen in FIG. 6. The bearing body can protrude from the fitting housing 44 with a connecting element 48 and can be used for the non-rotatable fixing of a handwheel 45.

Wie der Schnitt nach Fig. 6 zeigt, sind die Lagerwellen 40 in Lagerhülsen 46 drehbar gelagert, die in den Polsterelementen 10 zentrisch angeordnet sind. Beide als Mitnehmer 47 ausgebildeten Enden der Lagerwelle 40 sind mit einem Beschlag 20 gekoppelt und in deren Lagerkörper 41 unverdrehbar eingesteckt. Die von dem oberen Polsterelement 10 kommenden Verbindungslaschen laufen in die Beschlagteile 34 mit der Innenzahnkranzaufnahme aus, die die Zahnräder der Verbindungslaschen 30 aufnehmen, welche von dem in der Schlange nach unten folgenden Polsterelement 10 kommen. Die Lagerkörper 41 sind beim Ausführungsbeispiel nur an einem Ende der Lagerwelle 40 mit dem Handrad 45 versehen. Die Verbindungslaschen 30 laufen an dem oberen Polsterelement 10 als komplementäre Beschlagteile 31 aus und stehen im Eingriff mit den Beschlagteilen 34 der weiterführenden Verbindungslaschen 30.As the section according to FIG. 6 shows, the bearing shafts 40 are rotatably mounted in bearing sleeves 46 which are arranged centrally in the cushion elements 10. Both ends of the bearing shaft 40 designed as a driver 47 are coupled to a fitting 20 and inserted non-rotatably into the bearing body 41 thereof. The connecting lugs coming from the upper cushion element 10 run out into the fitting parts 34 with the internal toothed ring receptacle, which receive the gearwheels of the connecting lugs 30, which come from the cushion element 10 following down the line. In the exemplary embodiment, the bearing bodies 41 are provided with the handwheel 45 only at one end of the bearing shaft 40. The connecting straps 30 terminate on the upper cushion element 10 as complementary fitting parts 31 and are in engagement with the fitting parts 34 of the further connecting straps 30.

Die Verbindungslaschen sind bei diesem Ausführungsbeispiel gleich ausgebildet und an beiden Seiten der Schlange gleich ausgerichtet angeordnet. Die Beschlagteile 31 und 34 einer Verbindungslasche 30 können dabei auch um die Dicke der Verbindungslasche 30 gegeneinander versetzt sein, damit die Verbindungslaschen 30 jeweils in einer Ebene liegen. Dabei genügt es wenn einer der Beschlagteile 31 oder 34 gegenüber derverbindungslasche 30 um die Dicke der Verbindungslasche 30 versetzt ist.The connecting straps are of the same design in this exemplary embodiment and are arranged in the same direction on both sides of the snake. The fitting parts 31 and 34 of a connecting bracket 30 can also be offset from one another by the thickness of the connecting bracket 30, so that the connecting brackets 30 each lie in one plane. It is sufficient if one of the fitting parts 31 or 34 is offset by the thickness of the connecting tab 30 with respect to the connecting tab 30.

Die Ausgestaltung kann jedoch auch so sein, dass die Verbindungslaschen 30 an beiden Seiten der Schlange abwechselnd an beiden Enden als Innenzahnkranzaufnahme ausgebildete Beschlagteile 34 und an beiden Enden als Zahnräder ausgebildete Beschlagteile 31 tragen. Die Verbindungslaschen 30 liegen dann mit ihren Beschlagteilen 31 und 34 jeweils in einer Ebene und aufeinanderfolgende Verbindungslaschen 30 sind jeweils um die Dicke der Verbindungslaschen 30 abwechselnd nach innen und nach aussen versetzt. Die den Polsterelementen 10 zugekehrten Verbindungslaschen 30 mit den als Innenzahnkranzaufnahmen ausgebildeten Beschlagteilen 34 werden starr mit den Lagerwellen 40 verbunden, so dass sich rahmenartige stabile Gestellteile ergeben.However, the configuration can also be such that the connecting straps 30 on both sides of the coil alternately carry fitting parts 34 designed as an internal ring gear receptacle at both ends and fitting parts 31 designed as gear wheels on both ends. The connecting straps 30 then lie with their fitting parts 31 and 34 in one plane and successive connecting straps 30 are alternately offset inwards and outwards by the thickness of the connecting straps 30. The connecting straps 30 facing the cushion elements 10 with the fitting parts 34 designed as internal ring gear receptacles are rigidly connected to the bearing shafts 40, so that frame-like stable frame parts result.

Das Ausführungsbeispiel nach Fig. 7 zeigt einen besonders einfachen Beschlag, der mit Hilfe der Verbindungslasche 30 nach Fig. 8 gebildet wird. Die Beschlagteile 31 und 34 sind an den beiden Enden der Verbindungslasche 30 als Lochscheiben ausgebildet, die auf gleichem Durchmesser eine Reihe von Bohrungen 57 und 59 tragen. Die Lochscheiben tragen zusätzlich eine zentrische Durchgangsbohrung 56 bzw. 58. Wie Fig. 7 zeigt wird in das Polsterelement 10 eine als Hohlwelle ausgebildete Lagerwelle 40 eingesetzt, die durch die Lagerhülse 46 des Polsterelementes 10 geführt ist. Die Polsterelemente 10 können im Querschnitt rund sein, so dass diese Lagerhülse 46 zentrisch angeordnet ist. Es sind jedoch auch andere Querschnittsformen von Polsterelementen 10 in gleicher Weise miteinander koppelbar.The embodiment according to FIG. 7 shows a particularly simple fitting, which is formed with the aid of the connecting strap 30 according to FIG. 8. The fitting parts 31 and 34 are formed at the two ends of the connecting bracket 30 as perforated disks, which have a number of holes 57 and 59 on the same diameter. The perforated disks additionally carry a central through bore 56 or 58. As shown in FIG. 7, a bearing shaft 40 designed as a hollow shaft is inserted into the cushion element 10 and is guided through the bearing sleeve 46 of the cushion element 10. The cushion elements 10 can be round in cross section, so that this bearing sleeve 46 is arranged centrally. However, other cross-sectional shapes of cushion elements 10 can also be coupled to one another in the same way.

In die Enden der als Hohlwelle ausgebildeten Lagerwelle 40 sind Muttern 49 unverdrehbar und unverschiebbar festgelegt.In the ends of the bearing shaft 40 formed as a hollow shaft nuts 49 are fixed non-rotatably and immovably.

In die Gewindebohrung 50 der Mutter 49 ist das Gewindeteil 52 einschraubbar, das an der mit dem Griffteil 53 versehenen Arretierungsplatte 51 angebracht ist. Zwischen der Arretierungsplatte 51 und den fluchtend übereinander liegenden Beschlagteilen 31 und 34 der beiden aufeinander stossenden Verbindungslaschen 30 ist die Scheibe 54 angeordnet. Diese Scheibe 54 trägt Arretierungsbolzen 55, die in fluchtende Bohrungen 57 und 59 der Lochscheiben eingeführt sind, so dass diese in einer bestimmten Winkelstellung zueinander gehalten sind. Das Gewindeteil 52 der Arretierungsplatte 51 ist durch die Bohrungen 60, 56 und 58 der Scheibe 54 und der Beschlagteile 31 und 34eingeführt und in die Gewindebohrung 50 der Mutter 49 eingeschraubt, so dass die Scheibe 54 und die Beschlagteile 31 und 34 gegen die Stirnseite der Lagerwelle 40 verspannt und daran festgelegt sind.The threaded part 52, which is attached to the locking plate 51 provided with the grip part 53, can be screwed into the threaded bore 50 of the nut 49. The disk 54 is arranged between the locking plate 51 and the fitting parts 31 and 34 of the two abutting connecting straps 30, which are aligned one above the other. This disc 54 carries locking bolts 55 which are inserted into aligned bores 57 and 59 of the perforated discs, so that they are held in a certain angular position relative to one another. The threaded part 52 of the locking plate 51 is inserted through the bores 60, 56 and 58 of the washer 54 and the fitting parts 31 and 34 and screwed into the threaded bore 50 of the nut 49, so that the washer 54 and the fitting parts 31 and 34 against the end face of the bearing shaft 40 are tense and attached.

Wie im rechten Teil der Fig. 7 gezeigt ist, kann zwischen der Arretierungsplatte 51 und der Scheibe 54 mit den Arretierungsbolzen 55 ein weiteres Beschlagteil 62 angeordnet werden. Dieses Beschlagteil 62 muss nur eine Bohrung 61 zur Durchführung des Gewindeteiles 52 der Arretierungsplatte 51 aufweisen, Dieses Beschlagteil 62 kann z.B. als Fuss für das Polstermöbel ausgebildet sein.As shown in the right part of FIG. 7, a further fitting part 62 can be arranged between the locking plate 51 and the disk 54 with the locking bolts 55. This fitting part 62 only has to have a bore 61 for the threaded part 52 of the locking plate 51 to pass through. This fitting part 62 can e.g. be designed as a foot for the upholstered furniture.

Wie in Fig. 7 strichpunktiert angedeutet ist, kann die Verbindungslasche 30' auch abgewinkelt sein, so dass die Ebenen der beiden Beschlagteile 31 und 34 in einem vorgegebenen Winkel, z.B. 90° zueinander stehen. Die Verbindungslasche 30' verbindet dann zwei Polsterelemente 10 in diesem vorgegebenen Winkel zueinander. Dies ermöglicht z.B. seitlich zur Schlange Polsterelemente anzubringen, die senkrecht zu den Polsterelementen 10 der Schlange stehen.As indicated by dash-dotted lines in Fig. 7, the connecting tab 30 'can also be angled so that the planes of the two fitting parts 31 and 34 at a predetermined angle, e.g. Stand at 90 ° to each other. The connecting strap 30 'then connects two cushion elements 10 to one another at this predetermined angle. This enables e.g. to attach to the side of the snake cushion elements that are perpendicular to the cushion elements 10 of the snake.

Soll der Winkel zwischen zwei Polsterelementen 10 in kleinen Winkelbereichen verändert werden können, dann sind bei den Lochscheiben eine Vielzahl von Bohrungen 57 und 59 erforderlich. Werden in beiden Lochscheiben die gleiche Anzahl von Bohrungen eingebracht, dann ergibt sich die Anzahl der Bohrungen 57 und 59 aus dem Verhältnis von 360° zu dem gewünschten kleinsten Winkelbereich. Dabei ist dann noch zu beachten, dass bei mehr als einem Arretierungsbolzen 55 diese in gleichmässiger Winkelteilung angeordnet werden müssen und dass die Anzahl der Bohrungen 57 und 59 durch diese Anzahl der Arretierungsbolzen 55 teilbar sein muss.If the angle between two cushion elements 10 can be changed in small angular ranges, then a large number of bores 57 and 59 are required for the perforated disks. If the same number of holes is made in both perforated disks, the number of holes 57 and 59 results from the ratio of 360 ° to the desired smallest angular range. It should then also be noted that if there is more than one locking bolt 55, these must be arranged in a uniform angular pitch and that the number of bores 57 and 59 must be divisible by this number of locking bolts 55.

Wie Fig. 8 zeigt, kann die Anzahl der Bohrungen 57 und 59 in den Lochscheiben auch unterschiedlich gewählt werden. Damit erreicht man den gewünschten kleinsten Winkelbereich mit weniger Bohrungen 57 und 59. Bei dem Ausführungsbeispiel hat das Beschlagteil 31 acht Bohrungen 57 auf einem Kreis um die zentrische Durchgangsbohrung 56, die in einer Winkelteilung von 45° eingebracht sind. Das Beschlagteil 34 hat nur sechs Bohrungen 59, die in einer Winkelteilung von 60° um die zentrische Durchgangsbohrung 58 eingebracht sind. Die Arretierungsscheibe 51 trägt zwei um 180° versetzte Arretierungsbolzen 55. Die Anzahl der Bohrungen n 1 = 8 und n2=6 sind durch die Anzahl n = der Arretierungsbolzen 55 teilbar. Werden die beiden Beschlagteile 31 und 34 fluchtend übereinander angeordnet, dann kann in Winkelbereichen von 15° die Arretierungsplatte 51 mit den beiden Arretierungsbolzen 55 jeweils in ein um 180° versetztes Paar von fluchtenden Bohrungen 57 und 59 eingesteckt werden. Mit dieser Ausgestaltung der Beschlagteile 31 und 34 werden daher nicht mehr 360:15 = 24, sondern nur noch 8 bzw. 6 Bohrungen 57 bzw. 59 benötigt, um denselben gewünschten kleinsten Winkelbereich für die Verstellung zu bekommen.As shown in FIG. 8, the number of bores 57 and 59 in the perforated disks can also be different be chosen. The desired smallest angular range is thus achieved with fewer bores 57 and 59. In the exemplary embodiment, the fitting part 31 has eight bores 57 in a circle around the central through bore 56, which are introduced at an angle of 45 °. The fitting part 34 has only six bores 59 which are made at an angular pitch of 60 ° around the central through bore 58. The locking disc 51 carries two locking bolts 55 offset by 180 °. The number of bores n 1 = 8 and n2 = 6 can be divided by the number n = of the locking bolts 55. If the two fitting parts 31 and 34 are aligned one above the other, then the locking plate 51 with the two locking bolts 55 can be inserted into a pair of aligned bores 57 and 59 offset by 180 ° in angular ranges of 15 °. With this configuration of the fitting parts 31 and 34, 360: 15 = 24 are no longer required, but only 8 or 6 bores 57 or 59 are required in order to obtain the same desired smallest angular range for the adjustment.

Werden an der Arretierungsplatte 51 drei um 120° versetzte Arretierungsbolzen 55 angebracht, dann müssen die Anzahlen n1 und n2 der Bohrungen 57 und 59 in den Beschlagteilen 31 und 34 durch 3 teilbar sein. Wird n 1 = 12 und n2 = 9 gewählt, dann ergibt sich für n3=3 der kleinste Winkelbereich von (360°:9)-(360°:12) = 40°-30° = 10°, für den bei gleichen Beschlagteilen normalerweise jeweils 36 Bohrungen 57 und 58 erforderlich wären.If three locking bolts 55 which are offset by 120 ° are attached to the locking plate 51, then the numbers n1 and n2 of the bores 57 and 59 in the fitting parts 31 and 34 must be divisible by 3. If n 1 = 12 and n2 = 9 is selected, then the smallest angular range of (360 °: 9) - (360 °: 12) = 40 ° -30 ° = 10 ° results for n3 = 3, for the same fitting parts would normally require 36 holes 57 and 58 each.
