Fig. 1 zeigt die Seitenansicht eines Klappmöbels, bestehend aus einer Rückenlehne 1, einem Sitz 2, Armlehnen 3, Hinterbeinen 4 und Vorderbeinen 5. Zum Zusammenklappen des Klappmöbels sind an den Hinterbeinen 4 entlang des jeweiligen Hinterbeins und an seiner nach innen weisenden Fläche Führungen 6 vorgesehen, die in Fig. 1 gestrichelt angedeutet sind und bei einem Klappmöbel aus Holz in Form einer Nut in die Innenfläche der Hinterbeine 4 eingefräst sind. Bei Klappmöbeln aus Holz weist der Sitz 2 Seitenholme 7 und die Rückenlehne 1 Seitenholme 8 auf. Bei der dargestellten Ausführungsform sind die Seitenholme 8 über Verbindungsstücke 9 mit den Seitenholmen 7 verbunden. Die Verbindungsstücke 9 sind an den Seitenholmen 8 durch Stifte, Bolzen oder dergleichen drehfähig gelagert. Diese Stifte oder Bolzen sind mit 11 bezeichnet. Entsprechend sind die Verbindungsstücke 9 gegenüber den Seitenholmen 7 mit Stiften und Bolzen drehfähig gelagert. Außerdem ist üblicherweise die Armlehne am Seitenholm 8 drehfähig angelenkt und lagert drehfähig die oberen Enden der Vorder- und Hinterbeine 4, 5. Jedes Vorderbein 5 ist drehfähig an dem zugehörigen Seitenholm 7 befestigt. Wie aus Fig. 1 ersichtlich ist, greifen die z.B. stiftförmigen Führungselemente 11 in die durch eine Führungsnut am Hinterbein 4 gebildete Führung 6 ein, wobei die Führungselemente 11 auch an anderer Stelle des Klappmöbels vorgesehen sein können, z.B. an der Stelle der Stifte bzw. Bolzen 12 oder im Bereich der Verbindungsstücke 9.1 shows the side view of a folding piece of furniture, consisting of a backrest 1, a seat 2, armrests 3, rear legs 4 and front legs 5. To fold the folding piece of furniture, there are guides 6 on the rear legs 4 along the respective rear leg and on its inwardly facing surface Provided, which are indicated by dashed lines in Fig. 1 and are milled into the inner surface of the rear legs 4 in a folding piece of furniture made of wood in the form of a groove. In the case of folding furniture made of wood, the seat has 2 side rails 7 and the backrest 1 side rails 8. In the embodiment shown, the side rails 8 are connected to the side rails 7 via connecting pieces 9. The connectors 9 are rotatably mounted on the side rails 8 by pins, bolts or the like. These pins or bolts are designated 11. Accordingly, the connecting pieces 9 are rotatably supported with respect to the side rails 7 with pins and bolts. In addition, the armrest is usually pivoted on the side rail 8 and rotatably supports the upper ends of the front and rear legs 4, 5. Each front leg 5 is rotatably attached to the associated side rail 7. As can be seen from FIG. 1, the, for example, pin-shaped guide elements 11 engage in the guide 6 formed by a guide groove on the rear leg 4, the guide elements 11 also being able to be provided elsewhere on the folding furniture, for example the location of the pins or bolts 12 or in the area of the connecting pieces 9.

Die in Verbindung mit Fig. 1 beschriebene Führung 6 hat bei der in Fig. 2 gezeigten Ausführungsform die Form einer Nut, die am Hinterbein 4 in die innenliegende Fläche des Hinterbeins hineingefräst bzw. ausgearbeitet ist und über eine vorbestimmte Länge des Hinterbeins verläuft. Am oberen En de dieser Führungsnut 4 sind zwei Rastnuten 15, 16 vorgesehen, die im wesentlichen gleiche Form und Tiefe haben wie die Führungsnut 6 und direkt in die Führungsnut 6 übergehen. Die Rastnuten 15, 16 verlaufen im wesentlichen parallel zueinander und haben solchen Abstand zueinander, daß eine merkliche Verstellung der Neigung des Sitzes 2 erreichbar ist. Anstelle von zwei Rastnuten 15, 16 läßt sich auch eine größere Zahl derartiger Rastnuten vorsehen, die jeweils in die Führungsnut 6 münden, damit die Führungselemente 11 während der Verstellung des Klappmöbels aus der Führungsnut 6 in das jeweils gewünschte Rastnutenpaar, z.B. 15 oder 16, einrastbar sind. Bei der in Fig. 2 gezeigten Ausführungsform sind die Rastnuten 15 bzw. 16 jeweils unter einem stumpfen Winkel zur Führungsnut 6 vorgesehen. Diese Ausrichtung der Rastnuten gegenüber der Führungsnut 6 hat den Vorteil, daß die Führungselemente 11 aus der jeweiligen Rastnut nicht bereits bei Anlegen geringfügiger Kräfte an die Vorderkante des Sitzes 2 in die Führungsnut 6 zurücklaufen und damit ein unbeabsichtigtes Verstellen des Klappmöbels zur Folge haben können. Es kann aber auch ausreichend sein, wenn die Rastnuten 15, 16 usw. aus der Führungsnut 6 in horizontaler Richtung verlaufen. Weiter vorteilhaft kann es sein, wenn die Führungsnut 6 gegenüber der Achse der Hinterbeine geringfügig geneigt ist, wie dies in Fig. 2 dargestellt ist.The guide 6 described in connection with FIG. 1 has the shape of a groove in the embodiment shown in FIG. 2, which is milled or worked out on the rear leg 4 into the inner surface of the rear leg and extends over a predetermined length of the rear leg. At the upper En de this guide groove 4, two locking grooves 15, 16 are provided, which have substantially the same shape and depth as the guide groove 6 and go directly into the guide groove 6. The locking grooves 15, 16 run essentially parallel to one another and are spaced from one another such that a noticeable adjustment of the inclination of the seat 2 can be achieved. Instead of two locking grooves 15, 16, a larger number of such locking grooves can also be provided, each opening into the guide groove 6, so that the guide elements 11 during the adjustment of the folding furniture from the guide groove 6 into the respectively desired pair of locking grooves, e.g. 15 or 16, can be snapped into place. In the embodiment shown in FIG. 2, the locking grooves 15 and 16 are each provided at an obtuse angle to the guide groove 6. This alignment of the locking grooves with respect to the guide groove 6 has the advantage that the guide elements 11 do not run back out of the respective locking groove even when slight forces are applied to the front edge of the seat 2 into the guide groove 6 and can thus result in unintentional adjustment of the folding furniture. However, it may also be sufficient if the locking grooves 15, 16 etc. run out of the guide groove 6 in the horizontal direction. It can be further advantageous if the guide groove 6 is slightly inclined with respect to the axis of the rear legs, as shown in FIG. 2.

Die in Verbindung mit Fig. 2 erläuterte Führung mit Rastnuten kann sowohl bei einem Klappmöbel Anwendung finden, dessen Rückenlehne 1 verstellbar ist, wobei der Verstellmechanismus in die in Fig. 2 gezeigte Armlehne 3 integriert ist oder auch bei einem Klappmöbel, dessen Rückenlehne 1 entsprechend Fig. 1 nicht verstellbar ist.The guide with locking grooves explained in connection with FIG. 2 can be used both in a folding piece of furniture, the Backrest 1 is adjustable, the adjustment mechanism being integrated in the armrest 3 shown in FIG. 2 or also in the case of a folding piece of furniture, the backrest 1 of which is not adjustable in accordance with FIG. 1.

Fig. 3 zeigt eine weiter abgewandelte Ausführungsform bezüglich des Verstellmechanismus für die Sitzneigung. Die Führung 6 ist auch hier vorzugsweise durch eine entlang der Innenfläche der Hinterbeine 4 verlaufende Führungsnut gebildet und enthält im Gegensatz zur Ausführungsform nach Fig. 2 entlang der Führungsnut vorgesehene Vertiefungen oder Versenkungen bzw. Bohrungen, die mit 18, 19, 20 bezeichnet sind. Um eine Höhenverstellung zu erreichen, müssen bei dieser Ausführungsform seitlich verstellbare Stifte 21 vorgesehen werden, vorzugsweise in Form von Gewindeschrauben, die gegenüber einer Gewindehülse 22 in seitlicher Richtung verstellbar sind. Die Hülse 22, die ein dem Gewindestift 21 entsprechendes Innengewinde aufweist, ist in den Seitenholm 6 eingesetzt, durchsetzt ferner die jeweiligen Verbindungsstücke 9 und durchsetzt vorzugsweise auch noch ein Abstandselement bzw. einen Abstandsring 24, der üblicherweise bei Klappmöbeln zwischen Rückenlehne bzw. Sitz und den Beinen angeordnet wird. Zur Betätigung des Gewindestiftes 21 ist dieser an seinem zum Stuhlinneren gerichteten Ende mit einer Kugel 25 oder einem anderen Betätigungselement versehen und läßt sich damit gegenüber der fest in den Seitenholm 6 eingesetzten Gewindehülse 22 in die Führungsnut 6 hinein oder aus der Führungsnut 6 heraus verdrehen.Fig. 3 shows a further modified embodiment with respect to the adjustment mechanism for the seat inclination. Here too, the guide 6 is preferably formed by a guide groove running along the inner surface of the rear legs 4 and, in contrast to the embodiment according to FIG. 2, contains depressions or depressions or bores provided along the guide groove, which are denoted by 18, 19, 20. In order to achieve a height adjustment, laterally adjustable pins 21 must be provided in this embodiment, preferably in the form of threaded screws, which are adjustable laterally with respect to a threaded sleeve 22. The sleeve 22, which has an internal thread corresponding to the setscrew 21, is inserted into the side member 6, further passes through the respective connecting pieces 9 and preferably also passes through a spacer element or a spacer ring 24, which is usually found between the backrest or seat and the folding furniture Legs is arranged. To actuate the threaded pin 21, this is provided at its end facing the inside of the chair with a ball 25 or another actuating element and can thus be rotated relative to the threaded sleeve 22 firmly inserted into the side rail 6 into the guide groove 6 or out of the guide groove 6.

Fig. 4 zeigt drei entlang der Führungsnut 6 übereinander angeordnete Vertiefungen oder Versenkungen 18 bis 20, was bedeutet, daß bei dieser Ausführungsform der Sitz drei unterschiedliche Neigungen annehmen kann. Die Vertiefungen oder Versenkungen 18 bis 20 haben vorzugsweise kreisförmiges Profil, das dem Außendurchmesser des Stiftes 21 angepaßt ist. Zur Verstellung der Neigung des Sitzes 1 ist bei dieser Ausführungsform der Stift 21 um einen Betrag in Fig. 4 nach links zu drehen, damit er gerade aus der betreffenden Vertiefung, z.B. 18, herausverlagert ist, jedoch noch innerhalb der Führungsnut 6 verbleibt und nach Verstellung der Neigung des Sitzes in die jeweils zugehörige andere Vertiefung wieder eingeschraubt werden kann.Fig. 4 shows three depressions or recesses 18 to 20 arranged one above the other along the guide groove 6, which means that in this embodiment the seat can assume three different inclinations. The depressions or recesses 18 to 20 preferably have a circular profile which is adapted to the outer diameter of the pin 21. To adjust the In this embodiment, the inclination of the seat 1, the pin 21 is to be rotated to the left by an amount in FIG. 4, so that it has just been moved out of the relevant recess, for example 18, but still remains within the guide groove 6 and after adjusting the inclination of the Seat can be screwed back into the corresponding other recess.

Wie aus Fig. 3 hervorgeht, ist die Führungsnut im wesentlichen mittig an der Innenfläche des hinteren Beines 4 entlang verlaufend vorgesehen, d.h. in Höhe der Achse des Hinterbeins 4.As is apparent from Fig. 3, the guide groove is provided substantially centrally along the inner surface of the rear leg 4, i.e. at the level of the axis of the hind leg 4.

Es sei erwähnt, daß bei entsprechender Abwandlung der Verbindungsstücke 9 der Stift 21 auch im Bereich des Verbindungsstücks 9 vorgesehen sein kann, wobei bei entsprechend starkem Verbindungsstück 9 ein dem Stift 21 entsprechendes Innengewinde in dem vorzugsweise aus Metall bestehenden Verbindungsstück 9 direkt vorgesehen wird und sich dann der Einsatz einer Gewindehülse 22, wie in Verbindung mit Fig. 4 beschrieben ist, erübrigt. Weiterhin kann der Stift 21 mit zugehöriger Gewindehülse auch im Bereich des Holmes 7, d.h. anstelle der Stifte 12 und damit im Bereich des Sitzes 2 vorgesehen sein bei entsprechender Anpassung der Drehpunkte der Vorder- und Hinterbeine gegenüber Sitzfläche und Armlehnen.It should be mentioned that, with a corresponding modification of the connecting pieces 9, the pin 21 can also be provided in the area of the connecting piece 9, with an appropriately strong connecting piece 9 providing an internal thread corresponding to the pin 21 in the connecting piece 9, which is preferably made of metal, and then the use of a threaded sleeve 22, as described in connection with FIG. 4, is unnecessary. Furthermore, the pin 21 with the associated threaded sleeve can also be in the area of the spar 7, i.e. Instead of the pins 12 and thus be provided in the area of the seat 2 with a corresponding adjustment of the pivot points of the front and rear legs relative to the seat and armrests.

Nach einer weiteren Abwandlung der Erfindung wird anstelle des Gewindestiftes 21 ein Stift oder Bolzen vorgesehen, der vorzugsweise durch Federvorspannung in Richtung auf die Führungsnut 6 gedrückt wird und damit zur Verstellung der Neigung des Sitzes gegen die Federvorspannung in Richtung Stuhlmitte herausgezogen und nach Neueinstllung der Sitzneigung zwecks Arretierung in einer zugehörigen Rastvertiefung freigegeben werden muß.According to a further modification of the invention, a pin or bolt is provided instead of the threaded pin 21, which is preferably pressed by spring preload in the direction of the guide groove 6 and thus pulled out to adjust the inclination of the seat against the spring preload towards the center of the chair and for the purpose of re-adjusting the seat inclination Locking in an associated locking recess must be released.

Aus vorstehender Beschreibung ist ersichtlich, daß das Klappmöbel bezüglich des rechten Vorder- und Hinterbeins einerseits und des linken Vorder- und Hinterbeins andererseits und damit auch bezüglich der beschriebenen Verstelleinrichtung symmetrisch ausgebildet ist.From the above description it can be seen that the folding furniture with respect to the right front and rear legs on the one hand and the left front and rear legs on the other hand and thus also symmetrical with respect to the adjustment device described.

Die beschriebene Einrichtung zur Verstellung der Sitzneigung läßt sich vorzugsweise bei Klappmöbeln aus Holz, jedoch in gleicher Weise auch bei Klappmöbeln aus Kunststoff und/oder Metall in gleichfalls vorteilhafter Weise einsetzen.The described device for adjusting the seat inclination can preferably be used in the same way with folding furniture made of wood, but in the same way also with folding furniture made of plastic and / or metal.

Nachfolgend wird eine Verstellvorrichtung für Klappmöbel beschrieben, die es ermöglicht, das Klappmöbel in eine sehr kompakte Form, z.B. zum Zwecke der Aufbewahrung, zusammenzuklappen.An adjusting device for folding furniture is described below, which makes it possible to fold the folding furniture into a very compact form, e.g. for the purpose of storage, collapse.

Fig. 5 zeigt eine Seitenansicht eines Klappmöbels, das eine Rückenlehne 101 und einen Sitz 102 aufweist. Die Rückenlehne 101 weist Seitenholme 103 und der Sitz einen Seitenholm 104 auf. Die Rückenlehne 101 und der Sitz 102 sind an ihren Seitenholmen 103, 104 über ein Verbindungsstück 105, vorzugsweise aus Metall, miteinander verbunden, welches in an sich bekannter Weise mittels Stiften oder Bolzen 106, 107 and den aufeinander zu gewandten Enden der Seitenholme 103, 104 befestigt ist. Zu diesem Zweck ist in die einander zu gewandten Enden der beiden Seitenholme 103, 104 jeweils vorzugsweise ein Schlitz gefräst, in welchen das plattenförmige Verbindungsstück 105 eingreift und mittels der Stifte oder Bolzen 106, 107 drehfähig gegenüber den Seitenholmen 103, 104 gelagert wird. Über eine Schraube 108 ist jeder Seitenholm mit einem Vorderbein 110 drehfähig verbunden. In gleicher Weise ist eine Armlehne 111 an ihrem einen Ende über eine Schraube 112 oder dergleichen drehfähig mit dem zugehörigen Seitenholm 103 verbunden. Jedes Vorderbein 110 ist mit dem zugehörigen Hinterbein 113 vorzugsweise in gleicher Weise verbunden, wie dies in Bezug auf die Seitenholme 103, 104 beschrieben ist, nämlich mittels eines vorzugweise plattenförmigen Verbindungsstücks 114. Gemäß der dargestellten Ausführungsform sind die oberen Enden von Vorderbein 110 und Hinterbein 113 zur Aufnahme des Verbindungsstücks 114 geschlitzt, wobei das Verbindungsstück 114 durch Bolzen oder dergleichen in der noch zu beschreibenden Art drehfähig gegenüber den oberen Enden von Vorderbein 110 und Hinterbein 113 eingesetzt ist. Die Bolzen 107 ragen aus dem Seitenholm 103 seitlich nach außen und greifen in die Führungsnut 115 ein, die entlang der Innenfläche des Hinterbeins 113 über eine bestimmte, das Zusammenklappen des Klappmöbels ermöglichende Länge ausgebildet ist. Dies bedeutet, daß die Führungsnut 115 in der nach innen weisenden Fläche jedes Hinterbeins 113 vorgesehen ist. Dadurch wird die Relativbewegung des Verbindungsstücks 105 bzw. des unteren Endes der Holme 103 gegenüber dem Hinterbein 113 beim Auf- und Zusammenklappen des Klappmöbels gegenüber den festen Drehpunkten bei 108, 112 erreicht.5 shows a side view of a folding piece of furniture which has a backrest 101 and a seat 102. The backrest 101 has side rails 103 and the seat has a side rail 104. The backrest 101 and the seat 102 are connected to one another at their side rails 103, 104 via a connecting piece 105, preferably made of metal, which in a manner known per se by means of pins or bolts 106, 107 and at the ends of the side rails 103, 104 facing each other is attached. For this purpose, a slot is preferably milled into the ends of the two side rails 103, 104 facing each other, in which the plate-shaped connecting piece 105 engages and is rotatably mounted with respect to the side rails 103, 104 by means of the pins or bolts 106, 107. Each side rail is rotatably connected to a front leg 110 via a screw 108. In the same way, an armrest 111 is rotatably connected at one end to the associated side rail 103 via a screw 112 or the like. Each front leg 110 is preferably connected to the associated rear leg 113 in the same manner as described in relation to the side rails 103, 104, namely by means of a preferably plate-shaped one Connector 114. According to the illustrated embodiment, the upper ends of front leg 110 and rear leg 113 are slotted to receive connector 114, connector 114 being rotatably inserted relative to the upper ends of front leg 110 and rear leg 113 by bolts or the like in the manner to be described is. The bolts 107 protrude laterally outwards from the side rail 103 and engage in the guide groove 115, which is formed along the inner surface of the rear leg 113 over a certain length which enables the folding furniture to be folded up. This means that the guide groove 115 is provided in the inward facing surface of each rear leg 113. As a result, the relative movement of the connecting piece 105 or the lower end of the spars 103 with respect to the rear leg 113 is achieved when the folding furniture is opened and closed with respect to the fixed pivot points at 108, 112.

Die zur Verstellvorrichtung gehörende Armlehne 111 besteht bei der Ausführungsform nach Fig. 5 und 6 aus einer Stützfläche 111a, auf die in bekannter Weise der Arm aufgelegt werden kann. An die Stützfläche 111a ist ein etwa vertikal nach unten abstehendes Teil 116 angesetzt, welches an seiner oberen Kante vorzugsweise vollständig fest mit der Stützfläche 111a verbunden ist und gemäß Fig. 5 zur Befestigung der Armlehne 111 an dem zugehörigen Seitenholm 103 mittels der erwähnten Schraube 112 oder dergleichen dient. Obgleich das vertikale Teil 116 selbst durch Ausfräsungen die Form einer Rasteinrichtung erhalten kann, ist es gemäß Fig. 5 bevorzugt, daß das Teil 116 als Befestigungselement für eine Platte 117 mit Rastvertiefungen dient. Diese Platte 117, die auch als Rastplatte bezeichnet werden kann, weist einen leicht gebogenen, im wesentlichen aber in Richtung der Armlehne 111 bzw. der Stützfläche 111a verlaufenden Führungsschlitz 118 und vom Führungsschlitz 118 nach oben gehende Restvertiefungen 119 auf. Die Platte 117 ist von außen auf die im wesentlichen winkelförmige Armlehne 111 aufgesetzt mittels Befestigungselementen 121, 122. Diese Befestigungselemente sind bei der dargestellten Ausführungsform, wie dies in Verbindung mit Fig. 9 noch beschrieben wird, als Stifte an der Platte 117 seitlich des Führungsschlitzes 118 fest angebracht und werden zur Befestigung der Platte 117 in entsprechende Öffnungen oder Bohrungen hineingedrückt, die im Teil 116 in entsprechendem Abstand zueinander vorgesehen sind. Fig. 5a zeigt eine im Schnitt gehaltene Vorderansicht der rechten Armlehne des in Fig. 5 gezeigten Klappmöbels.In the embodiment according to FIGS. 5 and 6, the armrest 111 belonging to the adjusting device consists of a support surface 111a, on which the arm can be placed in a known manner. An approximately vertically downwardly projecting part 116 is attached to the support surface 111a, which is preferably completely firmly connected to the support surface 111a at its upper edge and, according to FIG. 5, for fastening the armrest 111 to the associated side rail 103 by means of the screw 112 or the like serves. 5, it is preferred that the part 116 serves as a fastening element for a plate 117 with locking recesses. This plate 117, which can also be referred to as a locking plate, has a slightly curved guide slot 118, which runs essentially in the direction of the armrest 111 or the support surface 111a, and residual recesses 119 going upward from the guide slot 118. The plate 117 is substantially angular from the outside Armrest 111 attached by means of fastening elements 121, 122. In the embodiment shown, as will be described in connection with FIG. 9, these fastening elements are fixedly attached to the plate 117 as pins on the side of the guide slot 118 and are used to fasten the plate 117 in a corresponding manner Openings or bores pressed in, which are provided in part 116 at a corresponding distance from one another. Fig. 5a shows a sectional front view of the right armrest of the folding furniture shown in Fig. 5.

Wie aus Fig. 5a ersichtlich ist, erstreckt sich die Stützfläche 111a vom vertikalen Teil 116 so weit nach außen in Horizontalrichtung, daß sie von oben den Verbindungsbereich zwischen dem Vorderbein 110 und dem Hinterbein 113 sowie die oberen Enden von Vorderbein 110 und Hinterbein 113 abdeckt.5a, the support surface 111a extends from the vertical part 116 so far outwards in the horizontal direction that it covers the connection area between the front leg 110 and the rear leg 113 and the upper ends of the front leg 110 and rear leg 113 from above.

Zum Eingriff in die Platte 117 ist ein Zapfen 123 vorgesehen, der an seinem zum Teil 116 zugewandten Ende einen Kopf 123a (Fig. 7) trägt, welcher in dem montierten Zustand der Verstellvorrichtung nach Fig. 5 und 6 zwischen der Platte 117 und dem Teil 116 beweglich geführt ist. Zu diesem Zweck ist die Platte 117 unter Einhaltung eines der Stärke des Kopfes 123a entsprechenden Abstandes an dem Teil 116 befestigt, z.B. mittels nicht dargestellter Distanzelemente, die im Bereich der Befestigungselemente 121, 122 auf der zum Teil 116 gewandten Fläche der Platte 117 vorgesehen sein können. Das zum Kopf 123a abgewandte Ende des Zapfens 123 sitzt im oberen Ende des hinteren Beins 113. Gemäß einer bevorzugten Ausführungsform ist vorgesehen, daß das obere Ende des hinteren Beins 113 eine Lagerhülse 125 trägt, die einerseits zur drehfesten Fixierung des Verbindungsstücks 114 gegenüber dem Hinterbein 113 dient und andererseits dazu vorgesehen ist, das kopflose Ende des Zapfens 123 zu lagern. Das andere Ende des Verbindungsstücks 114 ist mittels eines Bolzens oder dergleichen drehfähig am oberen Ende des Vorderbeins 110 gelagert. Zur Verstellung der Neigung der Rückenlehne 101 ist durch Anhebung der Armlehne 111 der Zapfen 123 entlang des Führungsschlitzes 118 zu verstellen und in diejenige Rastvertiefung einzurasten, welche der gewünschten Neigung der Rückenlehne 101 entspricht.To engage the plate 117, a pin 123 is provided which carries at its end facing the part 116 a head 123a (FIG. 7) which, in the assembled state of the adjusting device according to FIGS. 5 and 6, between the plate 117 and the part 116 is movably guided. For this purpose, the plate 117 is fixed to the part 116 while maintaining a distance corresponding to the thickness of the head 123a, for example by means of spacer elements (not shown), which can be provided in the area of the fastening elements 121, 122 on the surface of the plate 117 facing the part 116 . The end of the pin 123 facing away from the head 123a is located in the upper end of the rear leg 113. According to a preferred embodiment, it is provided that the upper end of the rear leg 113 carries a bearing sleeve 125 which, on the one hand, fixes the connecting piece 114 in a rotationally fixed manner relative to the rear leg 113 serves and on the other hand is intended to support the headless end of the pin 123. The other end of the connector 114 is rotatable at the upper end of the front leg 110 by means of a bolt or the like stored. To adjust the inclination of the backrest 101, the pin 123 must be adjusted along the guide slot 118 by lifting the armrest 111 and engaged in the latching recess which corresponds to the desired inclination of the backrest 101.

Wird das Klappmöbel aus der in Fig. 5 gezeigten Gebrauchsstellung in die in Fig. 6 dargestellten Aufbewahrungskonfiguration zusammengeklappt, kann es bei einer Ausführungsform des Klappmöbels zur Erlangung einer äußerst kompakten Aufbewahrungsform zweckmäßig sein, den Zapfen 123 in die vorderste und in Fig. 5 mit 119a bezeichnete Rastvertiefung zu verlagern oder in eine andere vorbestimmte Rastvertiefung. Zur Sicherstellung dieser Verlagerung des Zapfens 123 wird am Hinterbein 113 ein Anschlagelement 127 vorgesehen, das die Form eines Stiftes haben kann und auf der nach hinten weisenden Kante des Hinterbeins 113 in einem Abstand zu dem durch den Zapfen 123 definierten Drehpunkt vorgesehen ist, welcher etwa der Länge des Führungsschlitzes 118 entspricht. Während des Zusammenklappens des Klappmöbels gelangt das Anschlagelement 127 in Anlage zu der unteren Fläche der Stützfläche 111a und bewirkt dadurch ein Herausschwenken des Zapfens 123 aus einer der Rastvertiefungen 119, wodurch während des weiteren Zusammenklappens der Zapfen 123 in den Führungsschlitz 118 gelangt und zugleich der Anschlag 127 in eine ihm zugeordnete Aussparung 128 verlagert wird, die in der unteren Fläche der Armlehne 111 vorgesehen ist. Dadurch verhindert das in die Aussparung 128 im zusammengeklappten Zustand hineinverlagerte Anschlagelement 127, daß die Armlehne 111 und/oder die Beine 104, 105 in einer nicht vollständig parallelen Stellung verbleiben. Fig. 6 zeigt, daß das Anschlagelement 127 in Form eines Stiftes im vollständig zusammengeklappten Zustand des Klappmöbels in der Aussparung 128 zu liegen kommt, wobei der Zapfen 123 in der konstruktionsbedingt vorbestimmten Rastvertiefung 119a einzurasten vermag. Die vorbestimmte Rastvertiefung 119a entspricht bei der in Fig. 6 gezeigten Ausführungsform einer anderen Rastvertiefung als dies in Verbindung mit Fig. 5 beschrieben wurde.If the folding furniture is folded from the use position shown in FIG. 5 into the storage configuration shown in FIG. 6, it may be expedient in one embodiment of the folding furniture to obtain an extremely compact storage form, the pin 123 in the foremost and in FIG. 5 with 119a to shift designated locking recess or in another predetermined locking recess. To ensure this displacement of the pin 123, a stop element 127 is provided on the rear leg 113, which can have the shape of a pin and is provided on the rear-facing edge of the rear leg 113 at a distance from the pivot point defined by the pin 123, which is approximately the Length of the guide slot 118 corresponds. During the folding of the folding piece of furniture, the stop element 127 comes into contact with the lower surface of the support surface 111a and thereby causes the pin 123 to pivot out of one of the latching recesses 119, as a result of which the pin 123 enters the guide slot 118 during the further folding and, at the same time, the stop 127 is shifted into a recess 128 assigned to it, which is provided in the lower surface of the armrest 111. As a result, the stop element 127, which is displaced into the recess 128 in the folded state, prevents the armrest 111 and / or the legs 104, 105 from remaining in a position which is not completely parallel. Fig. 6 shows that the stop element 127 in the form of a pin comes to rest in the recess 128 in the fully collapsed state of the folding furniture, the pin 123 being able to engage in the design-determined predetermined recess 119a. The predetermined latching recess 119a corresponds to the embodiment shown in Fig. 6 of a different recess than that described in connection with Fig. 5.

Fig. 7 zeigt ein gegenüber Fig. 5 und 6 abgewandeltes Klappmöbel, bei dem die Armlehne zwei vertikal nach unten verlaufende Teile 116, 130 trägt. Die beiden Teile 116, 130 sind an der Stützfläche 111a befestigt. Unterschiedlich zur Ausführungsform nach Fig. 5 und 6 ist, daß zu dem Teil 116 zusätzlich das Teil 130 vorgesehen ist. Ersichtlicherweise können die Teile 116, 130 auch ein gegenüber der Stützfläche 111a integrales Element bilden, auch wenn das Teil 116 einerseits und die Teile 116, 130 andererseits in Verbindung mit Fig. 5, 6 und 7 als gegenüber der Stützfläche 11a zusätzlich zu befestigende Teile dargestellt sind. Der Abstand, den das Teil 130 zum Teil 116 einhält, ist geringfügig größer als die aus Fig. 7 ersichtliche Tiefe der Beine, insbesondere des Vorder- und Hinterbeins. Die Anordnung der Platte 117, des Zapfens 123 mit seinem Kopf 123a ist die gleiche, wie dies in Verbindung mit Fig. 5 und 6 beschrieben ist. Gleiche Teile gegenüber Fig. 5 und 6 sind in Fig. 7 folgende mit gleichen Bezugszeichen versehen.FIG. 7 shows a folding piece of furniture modified compared to FIGS. 5 and 6, in which the armrest carries two parts 116, 130 which run vertically downwards. The two parts 116, 130 are attached to the support surface 111a. Different from the embodiment according to FIGS. 5 and 6 is that part 130 is additionally provided for part 116. As can be seen, the parts 116, 130 can also form an integral element with respect to the support surface 111a, even if the part 116 on the one hand and the parts 116, 130 on the other hand in connection with FIGS. 5, 6 and 7 are shown as parts to be additionally fastened with respect to the support surface 11a are. The distance that the part 130 maintains from the part 116 is slightly greater than the depth of the legs, in particular the front and rear legs, as can be seen in FIG. 7. The arrangement of the plate 117, the pin 123 with its head 123a is the same as that described in connection with FIGS. 5 and 6. The same parts as in FIGS. 5 and 6 are provided with the same reference numerals in FIG. 7.

Wie aus der Darstellung nach Fig. 7 hervorgeht, bilden die Teile 116, 130 zugleich eine Führung für die oberen Enden der Beine 110, 113, wobei das Teil 130 gegenüber der Ausführungsform nach Fig. 5 und 6 einen Sichtschutz und einen mechanischen Schutz gegenüber der Verstellvorrichtung liefert. Die durch die beiden Teile 116, 130 festgelegte Aussparung oder Führung ist in Fig. 7 mit 131 bezeichnet und ist an dem in Fig. 8 vorderen Ende der Armlehne vorzugsweise verschlossen, wie durch das Bezugszeichen 132 veranschaulicht ist. An der zur Rückenlehne 101 gewandten Seite ist die Aussparung 131 dagegen nicht verschlossen, um ein Einlegen der Beine 110 und 113 in diese Aussparung 131 zum Zwecke des Zusammenklappens in die aus Fig. 6 ersichtliche Klappstellung zu ermöglichen. Wie aus Fig. 8 hervorgeht, wird während des Zusammenklappens das Hinterbein 113 in Richtung eines Pfeiles A bewegt, wodurch das Anschlagelement 127 in seiner strichpunktierten Stellung in Anlage zur unteren Fläche der Armlehne 111 gelangt und dadurch den Zapfen 123 aus seiner in eine Rastvertiefung 119 eingreifenden Position heraus in den Führungsschlitz 118 verlagert und dadurch eine Verschiebung des Zapfens 123 in Richtung eines Pfeils B entlang des Führungsschlitzes 118 in die vorbestimmte Rastvertiefung 119 hervorruft, so daß das Klappmöbel die in Fig. 6 gezeigte kompakte Form annehmen kann.7, the parts 116, 130 also form a guide for the upper ends of the legs 110, 113, the part 130 compared to the embodiment according to FIGS. 5 and 6 providing a visual protection and a mechanical protection against the Adjustment device delivers. The recess or guide defined by the two parts 116, 130 is designated by 131 in FIG. 7 and is preferably closed at the front end of the armrest in FIG. 8, as illustrated by reference number 132. On the other hand, on the side facing the backrest 101, the cutout 131 is not closed in order to enable the legs 110 and 113 to be inserted into this cutout 131 for the purpose of collapsing into the folded position shown in FIG. 6. 8, during the Collapsing the rear leg 113 moves in the direction of an arrow A, whereby the stop element 127 in its dash-dotted position comes into contact with the lower surface of the armrest 111 and thereby displaces the pin 123 out of its position engaging in a locking recess 119 into the guide slot 118 and thereby one Displacement of the pin 123 in the direction of an arrow B along the guide slot 118 in the predetermined locking recess 119 causes, so that the folding furniture can take the compact form shown in FIG. 6.

Die Platte 117 wird vorzugsweise mittels von ihr an ihren beiden Enden abstehenden Zapfen oder Stifte 121, 122 an dem Teil 116 befestigt. Bei der Ausführungsform nach Fig. 5 kann die Befestigung der Platte 117 durch von Stifte oder Zapfen 121, 122 mittels Schrauben erfolgen; es werden jedoch bevorzugt Stifte oder Zapfen 121, 122 verwendet, die in Vertiefungen bzw. Bohrungen des Teils 116 eingesetzt wer den, wobei die Bohrungen oder Vertiefungen 133 gleichen oder nur geringfügig größeren Durchmesser als die zugehörigen Zapfen 121, 122 haben, so daß eine sichere, aber dennoch lösbare Befestigung der Platte 117 am Teil 116 ermöglicht wird. Die den Zapfen 121, 122 zugeordneten Bohrungen oder Vertiefungen im Teil 116 sind von der Außenfläche bzw. von der Aussparung 131 her in das Teil 116 gebohrt. Wie insbesondere Fig. 7 und 9 zeigen, sitzt der Zapfen 123 mit seinem Kopf 123a derart verschiebbar innerhalb der Aussparung 131, wobei er in der Lagerhülse 125 gelagert ist, daß sein Kopf 123a in Anlage zum Teil 116 gelangen kann, während das freie Ende des Zapfens 123 geringfügigen Abstand zum Teil 130 einhält. Der Zapfen 123 mit seinem Kopf 123a hat eine Länge, die geringfügig kleiner ist als die Breite der zwischen den Teilen 116, 130 festgelegten Aussparung. Dadurch können die Teile 116, 130 eine Führungsfunktion gegenüber dem Zapfen 123 ausüben, wenn er zusammen mit dem oberen Ende des Hinterbeines 113 entlang des Führungsschlitzes 118 der Platte 117 verlagert wird.The plate 117 is preferably attached to the part 116 by means of pins or pins 121, 122 protruding from it at both ends thereof. In the embodiment according to FIG. 5, the plate 117 can be fastened by means of pins or pins 121, 122 by means of screws; however, pins or pins 121, 122 are preferably used, which are inserted into recesses or bores of part 116, the holes or recesses 133 having the same or only slightly larger diameters than the associated pins 121, 122, so that a safe one , but still releasable attachment of the plate 117 to the part 116 is made possible. The holes or depressions in the part 116 assigned to the pins 121, 122 are drilled into the part 116 from the outer surface or from the recess 131. 7 and 9 show in particular, the pin 123 with its head 123a is displaceable within the recess 131, being mounted in the bearing sleeve 125 such that its head 123a can come into contact with part 116, while the free end of the Pin 123 maintains a slight distance from part 130. The pin 123 with its head 123a has a length which is slightly less than the width of the recess defined between the parts 116, 130. This allows the parts 116, 130 to perform a guiding function with respect to the pin 123 when it is displaced together with the upper end of the rear leg 113 along the guide slot 118 of the plate 117.

Bei den in Verbindung mit Fig. 5 bis 8 dargestellten Ausführungsformen ist es bevorzugt, daß die Rückenlehne 101 durch die an ihrem unteren Ende vorgesehenen Stifte oder Bolzen 107 entlang einer Führung oder Führungsnut 115 geführt ist und der Stift 107 als Verbindungsteil mit dem Verbindungsstück 105 dient, um die Rückenlehne 101 mit dem Sitz 102 zu verbinden, der in ähnlicher Weise einen Stift 106 am rückwärtigen Teil des Sitzes bzw. der Seitenholme 104 trägt. Ferner ist bei beiden Ausführungsformen vorzugsweise im oberen Ende des hinteren Bein 113 die Lagerhülse 125 vorgesehen, die nicht nur zur Aufnahme des Zapfens 123 dient, sondern gleichzeitig als Verbindungsteil mit dem Verbindungsstück 114 zusammenwirkt, welches das obere Ende jeweils eines Hinterbeins 113 mit dem oberen Ende des zugehörigen vorderen Beins 110 verbindet. Das Verbindungsstück 114 ist am Vorderbein 110 durch einen entsprechenden Stift 120 gegenüber dem betreffenden Vorderbein 110 drehfähig gelagert.In the embodiments shown in connection with FIGS. 5 to 8, it is preferred that the backrest 101 is guided along a guide or guide groove 115 by the pins or bolts 107 provided at its lower end and the pin 107 serves as a connecting part with the connecting piece 105 to connect the backrest 101 to the seat 102, which similarly carries a pin 106 on the rear part of the seat or the side rails 104. Furthermore, in both embodiments, the bearing sleeve 125 is preferably provided in the upper end of the rear leg 113, which not only serves to receive the pin 123, but at the same time interacts as a connecting part with the connecting piece 114, which has the upper end of a rear leg 113 with the upper end of the associated front leg 110 connects. The connecting piece 114 is rotatably mounted on the front leg 110 by means of a corresponding pin 120 relative to the relevant front leg 110.

Der durch die beiden Teile 116, 130 festgelegte Zwischenraum bzw. Abstand ist somit geringfügig größer als die lichte Weite der in diesem Abstand aufgenommenen Abschnitte von Vorder- bzw. Hinterbein 110 bzw. 113. Da der Zapfen 123 eine etwa dem Abstand zwischen den beiden Teilen 116, 130 entsprechende Länge hat, kann im Falle des Auftretens von Querkräften das freie Ende des Zapfens 123 am Teil 130 in Anlage gelangen, wodurch vermieden wird, daß bei entsprechenden Querkräften quer zur Platte 117 der Kopf 123a des Zapfens 123 die Platte 117 aus ihrer Verankerung herauszieht.The space or distance defined by the two parts 116, 130 is thus slightly larger than the clear width of the sections of the front and rear legs 110 and 113 accommodated at this distance. Since the pin 123 is approximately the distance between the two parts 116, 130 has a corresponding length, in the event of the occurrence of transverse forces, the free end of the pin 123 can come into contact with the part 130, thereby preventing the head 123a of the pin 123 from being removed from the plate 123 with the corresponding transverse forces transverse to the plate 117 Pulls out anchor.

Zum Zwecke der Montage der Verstellvorrichtung wird die Platte 117 mittels des Zapfens 121 in die zugehörige Bohrung oder Vertiefung im Teil 116 eingesetzt, wonach der Zapfen 123 derart in den Führungsschlitz 118 eingesetzt wird, daß sein Kopf 123a zwischen der Platte 117 und dem Teil 116 zu liegen kommt.For the purpose of assembling the adjusting device, the plate 117 is inserted into the associated bore or recess in the part 116 by means of the pin 121, after which the pin 123 is inserted into the guide slot 118 in such a way that its head 123a is between the plate 117 and the part 116 comes to lie.

Gleichzeitig wird der Zapfen 123 in die Lagerhülse 125 eingesetzt, die vorzugsweise im oberen Ende des Hinterbeins 101 oder im Bereich des Verbindungsstücks 114 vorgesehen ist. Während der beschriebenen Montage des Zapfens 123 ist der den Stift 122 tragende Teil der Platte 117 aus der Aussparung 131 nach unten herausgeschwenkt und wird nach dem Einsetzen des Zapfens 123 in die in Fig. 9 gezeigte Position nach oben in die Aussparung 131 hinein verlagert, bis der Zapfen 122 in die für ihn vorgesehene Vertiefung oder Bohrung im Teil 116 einsetzbar ist, wobei diese Bohrung in Fig. 9 mit 133 angegeben ist. In umgekehrter Weise läßt sich die Verbindung zwischen dem oberen Ende des Hinterbeins bzw. dem Zapfen und der Platte 117 lösen.At the same time, the pin 123 is inserted into the bearing sleeve 125, which is preferably provided in the upper end of the rear leg 101 or in the region of the connecting piece 114. During the described assembly of the pin 123, the part of the plate 117 carrying the pin 122 is pivoted downward out of the recess 131 and, after the pin 123 has been inserted, is moved upward into the position 131 shown in FIG. 9 until the pin 122 can be inserted into the recess or bore provided for it in the part 116, this bore being indicated by 133 in FIG. 9. Conversely, the connection between the upper end of the rear leg or the pin and the plate 117 can be released.

Gemäß einer weiteren Abwandlung der Erfindung kann der Zapfen 123 mit einem Innengewinde versehen sein. Dies ist insbesondere zweckmäßig bei der Ausführungsform nach Fig. 5, bei welcher das äußere Teil 130 der Armlehne fehlt. Eine gestrichelt gezeigte Schraube wird von der Außenseite des oberen Endes des Hinterbeins 113 in den Zapfen 123 eingeschraubt und verhindert damit eine Verlagerung des Zapfens 123 aus der Lagerhülse 125 heraus infolge des Kopfes der Befestigungsschraube, deren Kopf größer als der Innendurchmesser der Lagerhülse zu wählen ist (Fig. 5a).According to a further modification of the invention, the pin 123 can be provided with an internal thread. This is particularly expedient in the embodiment according to FIG. 5, in which the outer part 130 of the armrest is missing. A screw shown in dashed lines is screwed into the pin 123 from the outside of the upper end of the rear leg 113 and thus prevents the pin 123 from being displaced out of the bearing sleeve 125 as a result of the head of the fastening screw, the head of which must be selected to be larger than the inside diameter of the bearing sleeve ( Fig. 5a).

Eine detaillierte Beschreibung der Verbindung zwischen den oberen Enden des Hinterbeins 113 und des Vorderbeins 110 einerseits sowie der Seitenholme 103, 104 andererseits ist nicht erforderlich, da derartige Verbindungen bekannt sind. Es sei lediglich bemarkt, daß zur Verbindung der erwähnten Teile übliche, der Breite dieser Teile entsprechende Verbindungsstücke oder Verbindungsplatten 105, 114 verwendet werden, die seitlich oder in mittige Schlitze an den Enden der Beine eingesetzt und durch entsprechende Stifte oder Lagerhülsen verankert werden.A detailed description of the connection between the upper ends of the rear leg 113 and the front leg 110, on the one hand, and the side rails 103, 104, on the other hand, is not necessary, since such connections are known. It should only be noted that for the connection of the parts mentioned, customary connecting pieces or connecting plates 105, 114 corresponding to the width of these parts are used, which are inserted laterally or in central slots at the ends of the legs and anchored by corresponding pins or bearing sleeves.
