Description

Die Erfindung betrifft ein Sitzmöbelstück mit einer bei der bestimmungsgemäßen Nutzung des Sitzmöbelstücks ortsfesten Basis, einer Sitzeinheit mit Sitzfläche und einer gegenüber der Sitzeinheit beweglichen Beineinheit mit Beinauflagefläche. Dabei ist die Beineinheit zwischen einer Staustellung, in der die Beineinheit unter der Sitzfläche angeordnet ist, und einer Nutzstellung, in der die Beineinheit vor der Sitzfläche angeordnet ist, mittels einer Bewegungsmechanik verlagerbar.The invention relates to a piece of seating furniture with a base fixed in the intended use of the piece of seating furniture, a seat unit with a seat surface and a leg unit with leg support surface which is movable relative to the seat unit. In this case, the leg unit is displaceable between a stowage position, in which the leg unit is arranged below the seat surface, and a use position, in which the leg unit is arranged in front of the seat, by means of a movement mechanism.

Gattungsgemäße Sitzmöbelstück sind aus dem Stand der Technik in vielfältigen Varianten bekannt.Generic seating furniture piece are known from the prior art in many variants.

Um eine ausreichend große Beinauflagefläche zu erzielen, gibt es Varianten, die neben der Beineinheit über ein separat bewegliches Endsegment verfügen. Bei diesen Gestaltungen ist zumeist vorgesehen, dass die Beineinheit gegenüber der Sitzeinheit verschwenkbar ist, zum Teil mittels Doppellaschen-Mechanismen. An die Beineinheit schließt sich dann zumeist ein schwenkbares Endsegment an. Dokumente, die solche oder ähnliche Gestaltungen mit Beinsegment und Endsegment zeigen, sind beispielsweise die DE 20000633 U1 , die BE 100 91 47 A3 , die DE 10 2008 009 234 A1 und die DE 3718645 C2 . Bei Gestaltungen, die auf ein Endsegment jenseits der Beineinheit verzichten, ist das Erreichen einer ausreichend großen Beinauflagefläche schwerer zu realisieren. Die DE 10 2005 001 877 A1 schlägt hierfür einen Mechanismus vor, bei der die Beineinheit größenveränderlich ist. Sie kann dadurch bei der Überführung aus der Nutzstellung in die Staustellung unterhalb der Sitzfläche verkleinert werden. Nur so ist es möglich, eine ausreichende Größe der Beinauflagefläche in der Nutzstellung und eine ausreichende Verkleinerung der Beineinheit in der verschwenkten Staustellung zu gewährleisten.In order to achieve a sufficiently large leg support surface, there are variants that have a separately movable end segment in addition to the leg unit. In these designs, it is usually provided that the leg unit is pivotable relative to the seat unit, in part by means of double-strap mechanisms. The leg unit closes then usually a pivotable end segment. Documents showing such or similar leg segment and end segment designs include, for example DE 20000633 U1 , the BE 100 91 47 A3 , the DE 10 2008 009 234 A1 and the DE 3718645 C2 , In designs that forego an end segment beyond the leg unit, achieving a sufficiently large leg rest area is more difficult to achieve. The DE 10 2005 001 877 A1 proposes for this a mechanism in which the leg unit is variable in size. It can thereby be reduced in the transfer from the use position to the stowed position below the seat. Only so it is possible to ensure a sufficient size of the leg support surface in the use position and a sufficient reduction of the leg unit in the pivoted stowed position.

Aufgabe und LösungTask and solution

Vorzugsweise soll erreicht werden, dass ein erfindungsgemäßes Sitzmöbelstück eine ausreichend große Beinauflagefläche bietet, ohne hierfür neben der Beineinheit ein hiergegen verlagerbares Endsegment aufzuweisen und ohne dass die Beineinheit in sich größenveränderlich ausgestaltet werden muss.Preferably, it is to be achieved that a piece of seating furniture according to the invention provides a sufficiently large leg support surface without having an end segment which can be displaced against it in addition to the leg unit and without the leg unit having to be made variable in size.

Erfindungsgemäß wird dies dadurch erzielt, dass die Bewegungsmechanik dafür ausgebildet ist, die Beineinheit von der Staustellung in der die Beinauflagefläche im Wesentlichen horizontal ausgerichtet ist, in die Nutzstellung zu überführen, in der die Beinauflagefläche ebenfalls im Wesentlichen horizontal ausgerichtet ist. Zur Erzielung dessen weist die Bewegungsmechanik einen Zwischenträger auf, welcher mittels einer Schwenkführung gegenüber der Sitzeinheit oder der Basis verlagerbar ist, wobei die Schwenkführung mindestens einen ersten Schwenkhebel zwischen dem Zwischenträger und der Sitzeinheit bzw. der Basis aufweist. Weiterhin weist ein erfindungsgemäßes Sitzmöbelstück eine Schiebeführung mit einem Schiebeglied auf, wobei das Schiebeglied translativ am Zwischenträger geführt ist und wobei die Beineinheit am Schiebeglied angebracht ist.This is achieved according to the invention in that the movement mechanism is designed to transfer the leg unit from the stowage position in which the leg support surface is oriented substantially horizontally into the use position, in which the leg support surface is likewise in the Is oriented substantially horizontally. To achieve this, the movement mechanism has an intermediate carrier, which is displaceable by means of a pivoting guide relative to the seat unit or the base, wherein the pivoting guide has at least one first pivoting lever between the intermediate carrier and the seat unit or the base. Furthermore, an inventive piece of seating furniture on a sliding guide with a sliding member, wherein the sliding member is translationally guided on the intermediate carrier and wherein the leg unit is mounted on the sliding member.

Die Angaben "vorne" und "hinten" betreffen die Möbellängsrichtung und beziehen sich auf die Perspektive des auf den Möbelstück Sitzenden, dessen Beine nach vorne weisen und dessen Rücken nach hinten weist.In the context of the following detailed description, the notion of high direction means a direction orthogonal to a footprint upon which the furniture stands. The indication of the transverse direction means an extension direction which extends horizontally parallel to the front edge of the seat. The furniture longitudinal direction is a direction orthogonal to the furniture transverse direction and furniture vertical direction. The indications "front" and "rear" refer to the furniture longitudinal direction and refer to the perspective of the person sitting on the piece of furniture, whose legs point forward and whose back points to the rear.

Die Besonderheit des erfindungsgemäßen Möbelstücks liegt darin, dass dieses dafür ausgebildet ist, die Beinauflage weitgehend horizontal zu verlagern. Von einer starken Schwenkbewegung, wie sie bei Gestaltungen des Standes der Technik zumeist vorgesehen ist, wird abgesehen. Die Beinauflage weist zumindest in der Staustellung und in der Nutzstellung die im Wesentlichen horizontale Ausrichtung auf, worunter zu verstehen ist, dass die Beinauflagefläche jeweils um nicht mehr als 25° gegenüber einer gedachten horizontalen Ebene verschwenkt ist. Vorzugsweise ist die Beineinheit während des gesamten Vorgangs der Überführung aus dem Stauzustand in den Nutzzustand in diesem Sinne im Wesentlichen horizontal ausgerichtet. Die genannte weitgehend gleich bleibende Orientierung der Beineinheit gestattet es, eine vergleichsweise große Beineinheit zu verwenden, da diese durch ihre Länge nicht, wie bei bekannten Gestaltungen, eine vergleichsweise hohe Sitzhöhe auf dem Sitzmöbelstück erzwingt. So kann die Länge der Beinauflage in Längsrichtung die Höhe des Freiraums unterhalb der Sitzeinheit übersteigen. Hierdurch wird es auch möglich, auf ein separat gegenüber der Beineinheit verlagerbares Endsegment zur Verlängerung der Beinauflagefläche zu verzichten.The peculiarity of the piece of furniture according to the invention is that it is designed to displace the leg rest largely horizontally. Of a strong pivoting movement, as provided for in the designs of the prior art usually is waived. The leg rest, at least in the stowage position and in the use position, has the essentially horizontal orientation, by which it is to be understood that the leg support surface does not extend more than 25 ° in each case an imaginary horizontal plane is pivoted. Preferably, the leg unit is aligned substantially horizontally throughout the process of transfer from the storage state to the use state in this sense. The said largely constant orientation of the leg unit makes it possible to use a comparatively large leg unit, since this does not enforce a comparatively high seat height on the seat piece of furniture as a result of its length, as in known designs. Thus, the length of the legrest in the longitudinal direction may exceed the height of the free space below the seat unit. This also makes it possible to dispense with a separately displaceable relative to the leg unit end segment for extending the leg support surface.

Um die Bewegung der Beineinheit aus der Staustellung in die Nutzstellung bewerkstelligen zu können, ist die Bewegungsmechanik der erläuterten Art vorgesehen. Diese Bewegungsmechanik verfügt über einen Zwischenträger, der schwenkbar an der Sitzeinheit oder der Basis vorgesehen ist. Die Basis wird dabei durch jene Teile des Sitzmöbelstücks gebildet, welche bei bestimmungsgemäßer Überführung des Möbelstücks aus der Nutzstellung in die Staustellung und umgekehrt stets ortsfest zu einem Untergrund verbleibt, auf dem das Möbelstück steht. Vorzugsweise handelt es sich um ein Gestell, an welchem auch die Füße des Möbelstücks vorgesehen sind.In order to accomplish the movement of the leg unit from the stowage position to the use position, the movement mechanism of the type explained is provided. This movement mechanism has an intermediate carrier which is pivotally provided on the seat unit or the base. The base is thereby formed by those parts of the piece of seating furniture, which always remains fixed to a substrate on which the piece of furniture is on intended transfer of the piece of furniture from the use position in the stowed position and vice versa. Preferably, it is a frame to which the feet of the piece of furniture are provided.

Die Sitzeinheit kann demgegenüber in nachfolgend noch erläuterter Weise beweglich sein. Die Bewegung des Zwischenträgers entlang einer Kreisbahn kann alternativ zueinander gegenüber der Sitzeinheit oder der Basis erfolgen. Der Zwischenträger selbst dient der translativen Führung eines Schiebegliedes, welches hierdurch in Möbellängsrichtung verlagerbar ist. Somit erfolgt die Verlagerung der Beineinheit gegenüber der Sitzeinheit bzw. der Basis durch zwei kumulativ verlagernd wirkende Teilmechanismen. Hierdurch wird das gewünschte Maß erreicht, um welches die Beineinheit zwischen ihrer Staustellung und ihrer Nutzstellung zu verlagern ist.In contrast, the seat unit can be movable in the manner explained below. The movement of the intermediate carrier along a circular path can alternatively take place relative to the seat unit or the base. The intermediate carrier itself serves for the translational guidance of a sliding member, which is thereby displaceable in the longitudinal direction of the furniture. Thus, the displacement of the leg unit relative to the seat unit or the base by two cumulatively displacing acting sub-mechanisms. This will achieve the desired level to which is the leg unit to move between its stowed position and its use position.

Die Verwendung zweier Mechanismen, um die gewünschte Verlagerungsstrecke gemeinsam zu erzielen, führt dazu, dass die beiden Mechanismen, die Schwenkführung und die Schiebeführung, jeweils nur einen Teil der gewünschten Verlagerungsstrecke leisten müssen. Daher können vorzugsweise auch vergleichsweise kurze Hebel zwischen dem Zwischenträger einerseits und der Basis oder Sitzeinheit andererseits Verwendung finden. Vorzugsweise weisen diese Hebel eine Länge zwischen ihren Anlenkpunkten von nicht mehr als 40 cm auf, vorzugsweise von nicht mehr als 30 cm auf.The use of two mechanisms in order to achieve the desired displacement distance together, means that the two mechanisms, the pivot guide and the sliding guide, each have to make only part of the desired displacement distance. Therefore, preferably comparatively short levers between the intermediate carrier on the one hand and the base or seat unit on the other hand can be used. Preferably, these levers have a length between their articulation points of not more than 40 cm, preferably not more than 30 cm.

Die Schiebeführung, die die Bewegung der Beineinheit gegenüber dem Zwischenträger ermöglicht, ermöglicht vorzugweise eine Verlagerung der Beineinheit gegenüber dem Zwischenträger von mindestens 10 cm, vorzugsweise von mindestens 15 cm. Unter einer Schiebeführung im Sinne der Erfindung ist eine Führung des Schiebegliedes gegenüber dem Zwischenträger zu verstehen, die insbesondere durch eine Gleitführung oder eine Rollenführung oder aber durch eine andere für die Herstellung einer translativen Relativverlagerbarkeit geeignete Führung realisiert ist. Vorzugsweise ist die translative Bewegung eine lineare Bewegung.The sliding guide, which allows the movement of the leg unit relative to the intermediate carrier, preferably allows a displacement of the leg unit relative to the intermediate carrier of at least 10 cm, preferably of at least 15 cm. Under a sliding guide according to the invention is a guide of the sliding member relative to the intermediate carrier to understand, which is realized in particular by a sliding guide or a roller guide or by another suitable for the production of a translational Relativverlagerbarkeit guide. Preferably, the translational motion is a linear motion.

Die Verlagerung des Schiebegliedes gegenüber dem Zwischenträger kann je nach Ausgestaltung des Sitzmöbelstücks nicht nur der Verlagerung der Beineinheit nach vorne dienen, sondern gestattet auch in vorteilhafter Weise eine Schwenkbewegung der Beineinheit gegenüber dem Zwischenträger, die im weiteren noch erläutert wird.The displacement of the sliding member relative to the intermediate carrier can serve not only the displacement of the leg unit to the front, but also advantageously allows a pivoting movement of the leg unit relative to the intermediate carrier, which will be explained in more detail depending on the configuration of the seat piece of furniture.

In Hinblick auf die Anbindung des Zwischenträgers an der Sitzeinheit oder der Basis ist grundsätzlich denkbar, dass der Träger als Ganzes fest mit dem ersten Schwenkhebel verbunden ist und somit hinsichtlich seiner Ausrichtung der Schwenkbewegung folgt. Von Vorteil ist es jedoch, wenn der erste Schwenkhebel einerseits um eine Schwenkachse schwenkbar an der Sitzeinheit oder der Basis angelenkt ist und andererseits auch nur eine zweite Schwenkachse schwenkbar am Zwischenträger angelenkt ist. Hierdurch kann verhindert werden, dass der Zwischenträger in gleichem Maße schwenkt, in dem dies für die Schwenkhebel gilt. Er kann daher im Sinne einer weitgehend beibehaltenden horizontalen Ausrichtung der Beineinheit durch die Schwenkführung verlagert werden, ohne hierbei in wesentlichem Maße seine Ausrichtung zu verändern.With regard to the connection of the intermediate carrier to the seat unit or the base is in principle conceivable that the carrier as a whole is firmly connected to the first pivot lever and thus follows in terms of its orientation of the pivoting movement. It is advantageous, however, if the first pivot lever is articulated on the one hand about a pivot axis pivotally mounted on the seat unit or the base and on the other hand, only a second pivot axis is pivotally articulated to the intermediate carrier. In this way it can be prevented that the intermediate carrier pivots to the same extent, in which this applies to the pivot lever. It can therefore be displaced by the pivot guide in the sense of a largely maintaining horizontal alignment of the leg unit, without significantly changing its orientation.

Um dennoch eine definierte Verlagerung des Zwischenträgers zu gestatten, sind vorzugsweise Zwangsführungsmittel vorgesehen, durch die jeder Schwenkstellung des ersten Schwenkhebels gegenüber der Sitzeinheit bzw. gegenüber der Basis eine hierdurch bewirkte Schwenkstellung des Zwischenträgers gegenüber dem ersten Schwenkhebel zugeordnet ist. Solche Zwangsführungsmittel führen somit zu der gewünschten Bestimmtheit der Bewegung des Zwischenträgers. Vorzugsweise ist diese Bewegung so geartet, dass der Zwischenträger bei der Überführung der Beineinheit von der Staustellung in die Nutzstellung um nicht mehr als 20° verschwenkt wird. Als besonders vorteilhaft hat sich eine Ausgestaltung der Zwangsführungsmittel herausgestellt, bei der die Schwenkführung einen zweiten Schwenkhebel aufweist, welcher um eine gegenüber der ersten Schwenkachse beabstandete dritte Schwenkachse schwenkbar an der Sitzeinheit oder der Basis angelenkt ist und andererseits um eine gegenüber der zweiten Schwenkachse beabstandete vierte Schwenkachse schwenkbar am Schwenkträge angelenkt ist. Somit ist die Schwenkführung als Doppelhebel-Schwenkführung ausgebildet. Durch identische oder weitgehend identische (+/- 20%) Länge der Schwenkhebel zwischen ihrem jeweiligen Anlenkpunkten wird die weitgehend horizontale Verlagerung des Zwischenträgers erreicht.In order nevertheless to allow a defined displacement of the intermediate carrier, positive guidance means are preferably provided by which each pivot position of the first pivot lever relative to the seat unit or relative to the base is caused a pivotal position of the intermediate carrier relative to the first pivot lever. Such positive guidance means thus lead to the desired definiteness of the movement of the subcarrier. Preferably, this movement is such that the intermediate carrier is pivoted in the transfer position of the leg unit from the stowed position to the use position by not more than 20 °. Particularly advantageous is an embodiment of the positive guide means has been found in which the pivot guide has a second pivot lever which is pivotally mounted about a first pivot axis spaced from the third pivot axis pivotally mounted on the seat unit or the base and on the other hand to a relation to the second pivot axis spaced fourth pivot axis pivotally hinged on pivoting applications. Thus, the pivot guide is designed as a double lever pivot guide. By identical or largely identical (+/- 20%) length of the pivot lever between their respective articulation points, the largely horizontal displacement of the intermediate carrier is achieved.

Die Besonderheit, die sich aus der Verwendung der Schwenkführung zwischen Basis oder Sitzeinheit einerseits und Zwischenträger andererseits sowie der Verwendung der Schiebführung ergibt, liegt insbesondere darin, dass der Zwischenträger zum überwiegenden Teil stets unterhalb der Sitzfläche verbleiben kann. Dies gilt insbesondere für die Anlenkpunkte des ersten und ggf. auch des zweiten Schwenkhebels. Vorzugsweise sind diese derart angeordnet, dass sie unabhängig von der Position des Zwischenträgers vollständig rückwärtig einer vorderen Kante der Sitzfläche verbleiben. Somit wird erreicht, dass die Bewegung des Zwischenträgers gegenüber der Sitzfläche oder der Basis durch eine Schwenkführung erfolgt, welche sehr gut vor den Augen des Benutzers versteckt werden kann. Dies ist insbesondere dann von Vorteil, wenn die genannten Schwenkhebel bezogen auf die Querrichtung außenseitig der Sitzfläche vorgesehen sind. Mechanische Komponenten, die sich links und rechts von der Sitzfläche bis vor die vordere Kante der Sitzfläche erstrecken, werden als ästhetisch nachteilig angesehen und bilden im Übrigen auch erhebliche Möglichkeiten, sich zu verletzen.The peculiarity which results from the use of the pivoting guide between the base or seat unit on the one hand and the intermediate support on the other hand and the use of the sliding guide is, in particular, that the intermediate support can for the most part always remain below the seat surface. This applies in particular to the articulation points of the first and possibly also of the second pivoting lever. Preferably, these are arranged such that they remain completely rearward of a front edge of the seat regardless of the position of the intermediate carrier. Thus, it is achieved that the movement of the intermediate carrier relative to the seat surface or the base is effected by a pivoting guide, which can be hidden very well in front of the user's eyes. This is particularly advantageous when said pivot lever are provided on the outside of the seat relative to the transverse direction. Mechanical components that extend to the left and right of the seat to the front edge of the seat, are considered to be aesthetically disadvantageous and also form considerable opportunities to injure themselves.

Es wird demnach als besonders vorteilhaft angesehen, wenn nur mechanische Komponenten der Schiebeführung in der Nutzstellung der Beineinheit von außen und aus üblichen Perspektiven ersichtlich sind.It is therefore considered particularly advantageous if only mechanical components of the sliding guide in the use position of the leg unit from the outside and from usual perspectives are visible.

Grundsätzlich ist denkbar, dass die Schiebeführung und die Schwenkführung mechanisch unabhängig sind, so dass sie separat vom Benutzer beeinflusst werden können. Im Sinne einer bequemen Handhabung wird es jedoch als vorteilhaft angesehen, wenn die Schwenkführung und die Schiebeführung miteinander wirkgekoppelt sind, so dass sich in Abhängigkeit der Relativlage des Zwischenträgers gegenüber der Sitzeinheit bzw. der Basis eine hiervon abhängige Relativstellung des Schiebegliedes zum Zwischenträger einstellt.In principle, it is conceivable that the sliding guide and the pivoting guide are mechanically independent, so that they can be influenced separately by the user. In terms of convenient handling, however, it is considered advantageous if the pivot guide and the sliding guide are operatively coupled to each other, so that adjusts depending on the relative position of the intermediate carrier relative to the seat unit or the base of a dependent relative position of the sliding member to the intermediate carrier.

Vorgesehen ist demnach, dass die Bewegung des Zwischenträgers gegenüber der Sitzeinheit oder der Basis entlang einer kreisabschnittsförmigen Bahn mittelbar auch die Bewegung des Schiebegliedes gegenüber dem Zwischenträger verursacht. Dabei erfolgt die Bewegung des Schiebegliedes in im Wesentlichen übereinstimmender Richtung mit der Bewegung des Zwischenträgers. Während der Zwischenträger somit gegenüber der Basis oder der Sitzeinheit in geringerem Maße nach vorne verlagert wird, wird die Beineinheit gleichzeitig in verstärktem Maße nach vorne verlagert.It is therefore provided that the movement of the intermediate carrier relative to the seat unit or the base along a circular segment-shaped path indirectly also causes the movement of the sliding member relative to the intermediate carrier. In this case, the movement of the sliding member takes place in substantially coincident direction with the movement of the intermediate carrier. While the intermediate support is thus displaced to the front to a lesser extent relative to the base or seat unit, the leg unit is simultaneously displaced forward to a greater extent.

Zur Erzielung der genannten Wirkkopplung zwischen der Schwenkführung und der Schiebeführung hat sich als besonders vorteilhaft herausgestellt, wenn dies über einen Steuerhebel bewirkt wird, der am Zwischenträger, am Schiebeglied und an der Basis oder der Sitzeinheit oder aber an einem der Schwenkhebel angelenkt ist. Dabei ist dieser Steuerhebel vorzugsweise um eine in vertikale Achse schwenkbar am Zwischenträger gelagert. Diese Anordnung mit einer vertikalen Schwenkachse des Steuerhebels führt allerdings dazu, dass dessen Anlenkpunkte zur Zusammenwirkung mit dem Schiebeglied einerseits bzw. der Basis, der Sitzeinheit oder einem der Schwenkhebel andererseits entlang einer Kreisbogenform erfolgt, so dass hier Zwischenhebel erforderlich sein können. Auch eine solche Gestaltung mit Zwischenhebel oder einer stattdessen vorzusehen Gleitführung ist als Anlenkung im Sinne der obigen Ausführungen zum Steuerhebel zu verstehen.To achieve said active coupling between the pivot guide and the sliding guide has been found to be particularly advantageous if this is effected via a control lever which is articulated on the intermediate carrier, the sliding member and the base or the seat unit or on one of the pivot lever. In this case, this control lever is preferably mounted about a pivotable in vertical axis on the intermediate carrier. However, this arrangement with a vertical pivot axis of the control lever causes its pivot points for interaction with the sliding member on the one hand or the base, the seat unit or one of the pivot lever on the other hand along a circular arc shape, so that here intermediate lever may be required. Even such a design with intermediate lever or one instead provide sliding is to be understood as articulation in the sense of the above remarks on the control lever.

Der vorgeschlagene Steuerhebel wird durch die Relativbewegung des Zwischenträgers gegenüber der Sitzeinheit oder der Basis verschwenkt und überträgt diese Schwenkbewegung auf die Schiebeführung, wodurch das Schiebeglied gegenüber dem Zwischenträger verlagert wird.The proposed control lever is pivoted by the relative movement of the intermediate carrier relative to the seat unit or the base and transmits this pivotal movement on the sliding guide, whereby the sliding member is displaced relative to the intermediate carrier.

Grundsätzlich ist es möglich, an einem distalen Ende des Schiebegliedes die Beinauflage derart zu befestigen, dass diese nicht mehr gegenüber dem Schiebeglied beweglich ist. Von Vorteil ist jedoch eine schwenkbare Anlenkung der Beinauflage am Schiebeglied.In principle, it is possible to fasten the leg rest to a distal end of the sliding member in such a way that it is no longer opposite the sliding element is movable. However, an advantage is a pivotable articulation of the leg rest on sliding element.

Dies gilt insbesondere für eine Weiterbildung der Erfindung, bei der vorgesehen ist, dass am Zwischenträger ein Fortsatz angebracht ist, der sich bis zur Beinauflage erstreckt. Dabei verfügt die Beineinheit über eine Schwenkmechanik, wobei diese Schwenkmechanik dafür ausgebildet ist, in Abhängigkeit der Relativstellung des Schiebegliedes zum Fortsatz ein Verschwenken der Beineinheit gegenüber dem Schiebeglied zu bewirken.This is especially true for a development of the invention, in which it is provided that an extension is attached to the intermediate carrier, which extends to the leg rest. In this case, the leg unit has a pivoting mechanism, wherein this pivoting mechanism is adapted to effect depending on the relative position of the sliding member to the extension pivoting of the leg unit relative to the sliding member.

Bei dieser Gestaltung erstreckt sich somit nicht allein das Schiebeglied bis zur Beinauflage, sondern auch ein Fortsatz, der Teil des Zwischenträgers ist oder mit diesem fest verbunden ist. Da im Zuge der Überführung der Beineinheit in die Nutzstellung eine Relativverlagerung des Schiebegliedes gegenüber dem Zwischenträger stattfindet, findet auch eine Verlagerung des Schiebegliedes gegenüber diesem Fortsatz statt. Gemäß dieser Weiterbildung wird diese Relativbewegung verwendet, um die Beineinheit zu verschwenken. Dies gestattet es, eine besonders ergonomische Position der Beineinheit in der Nutzstellung zu bewirken. Insbesondere gestattet es diese Schwenkmechanik, die Bewegungsmechanik im Übrigen auf den Bewegungspfad der Beineinheit zwischen der Nutzstellung und der Staustellung zu optimieren, da eine sich bei dieser Optimierung einstellende möglicherweise nicht ideale Ausrichtung der Beineinheit in der Nutzstellung durch die zusätzliche Schwenkmechanik korrigiert werden kann.In this design, not only the sliding member thus extends to the leg rest, but also an extension which is part of the intermediate carrier or is firmly connected thereto. Since a relative displacement of the sliding member relative to the intermediate carrier takes place in the course of the transfer of the leg unit in the use position, also a displacement of the sliding member relative to this extension takes place. According to this development, this relative movement is used to pivot the leg unit. This makes it possible to effect a particularly ergonomic position of the leg unit in the use position. In particular, this pivoting mechanism makes it possible to optimize the movement mechanism on the movement path of the leg unit between the use position and the stowed position, since a possibly not ideal alignment of the leg unit in the use position can be corrected by the additional pivoting mechanism in this optimization.

Der Fortsatz kann darüber hinaus der Verbesserung der Kippstabilität der Beineinheit dienen.The extension can also serve to improve the tilt stability of the leg unit.

Da gemäß der genannten Weiterbildung sowohl der Fortsatz als auch das Schiebeglied sich zwischen der Sitzeinheit und der Beineinheit erstrecken und somit in der Nutzstellung der Beineinheit je nach Ausgestaltung des Sitzmöbelstücks für den Benutzer sichtbar sind, wird es als besonders vorteilhaft angesehen, wenn Wandungen des Fortsatzes einen Innenraum umgeben, innerhalb dessen das Schiebeglied beweglich angeordnet ist. Somit ist das Vorhandensein zweier relativ zueinander beweglicher Komponenten für den Benutzer nicht erkennbar. Das Schiebeglied ist innerhalb des Fortsatzes versteckt. Grundsätzlich ist auch eine umgekehrte Anordnung denkbar, bei der das Schiebeglied einen Innenraum definiert, innerhalb dessen der Fortsatz angeordnet ist. Der Innenraum muss dabei nicht vollständig abgeschlossen sein. Allerdings wird es im Sinnen der Stabilität als vorteilhaft angesehen, wenn der Fortsatz tatsächlich als geschlossenes Hohlprofil ausgebildet ist, innerhalb dessen das Schiebeglied gleitend oder durch Rollen geführt beweglich ist.Since according to the said development, both the extension and the sliding member between the seat unit and the leg unit extend and thus in the use position of the leg unit depending on the configuration of the piece of seating furniture are visible to the user, it is considered particularly advantageous if walls of the extension surrounding an interior, within which the sliding member is movably arranged. Thus, the presence of two relatively movable components for the user is not recognizable. The sliding member is hidden within the extension. In principle, a reverse arrangement is conceivable in which the sliding member defines an interior, within which the extension is arranged. The interior does not have to be completely completed. However, it is regarded in the sense of stability as advantageous if the extension is actually formed as a closed hollow profile, within which the sliding member is sliding or guided by rollers movable.

Der Fortsatz und/oder das Schiebeglied sind dabei bezogen auf eine Querrichtung des Möbelstücks vorzugsweise in einem Mitteilbereich angeordnet, der maximal ein Drittel der Breite der Sitzfläche einnimmt. Dies führt zu der ästhetisch vorteilhaften Gestaltung, bei der zwischen der Sitzeinheit und der Beineinheit von außen kaum mehr zu erkennen ist, als ein unauffälliges Rohr.The extension and / or the sliding member are preferably arranged in relation to a transverse direction of the furniture in a Mitteilbereich occupying a maximum of one third of the width of the seat. This leads to the aesthetically advantageous design, in which between the seat unit and the leg unit from the outside hardly recognizable, as an inconspicuous pipe.

Die Schwenkmechanik, die der Beineinheit zugeordnet ist, weist vorzugsweise einen um eine ortsfest zum Schiebeglied angeordnete fünfte Schwenkachse schwenkbaren Schwenkträger auf, der ortsfest zur Beineinheit vorgesehen ist. Somit ist durch diesen Schwenkträger realisiert, dass die Beineinheit gegenüber dem Schiebeglied lediglich um eine gegenüber Schiebeglied und Beineinheit ortsfeste Schwenkachse schwenkbeweglich ist. Zur Realisierung der Schwenkbewegung ist vorzugsweise vorgesehen, dass die Schwenkmechanik eine Kulissenführung mit einer Kulissenbahn und einem Kulissengleiter aufweist, über die der Schwenkträger mit dem Fortsatz wirkgekoppelt ist. Somit führt eine Relativbewegung des Fortsatzes gegenüber dem Schiebeglied zu der gewünschten Schwenkverlagerung der Beineinheit gegenüber dem Schiebeglied. Die Kulissenführung gestattet hier eine besonders flexible Steuerung. So kann beispielsweise erreicht werden, dass die Schwenkbewegung der Beineinheit gegenüber dem Schiebeglied erst in einer letzten Phase bei der Überführung der Beineinheit in die Nutzstellung stattfindet. Vorzugsweise umfasst die Kulissenführung zwei Kulissenbahnen, welche in zwei zueinander parallelen Blechen vorgesehen sind, welche wiederum in Querrichtung des Möbelstücks beabstandet sind. Hierdurch wird ein hohes Maß an Verwindungssteifigkeit der Beineinheit erzielt. Die Kulissenbahnen sind vorzugsweise nicht-linear.The pivoting mechanism, which is associated with the leg unit, preferably has a pivotable about a stationary to the sliding member fifth pivot axis pivoting carrier, which is provided fixed to the leg unit. Thus, it is realized by this pivoting support that the leg unit relative to the sliding member is only pivotable about a pivot axis stationary relative to sliding member and leg unit. To realize the pivoting movement is preferably provided that the pivoting mechanism has a slotted guide with a slide track and a sliding block, via which the pivot support is operatively coupled to the extension. Thus leads a relative movement of the extension relative to the sliding member to the desired pivotal displacement of the leg unit relative to the sliding member. The slotted guide allows a particularly flexible control. For example, it can be achieved that the pivotal movement of the leg unit relative to the sliding member takes place only in a final phase during the transfer of the leg unit into the use position. Preferably, the slide guide comprises two slide tracks, which are provided in two mutually parallel sheets, which in turn are spaced in the transverse direction of the piece of furniture. As a result, a high degree of torsional rigidity of the leg unit is achieved. The slide tracks are preferably non-linear.

Weiterhin wird es als besonders vorteilhaft angesehen, wenn die Sitzeinheit gegenüber der Basis des Sitzmöbelstücks verlagerbar ausgebildet ist, wie es eingangs bereits erläutert wurde. Dabei ist die Relativbewegung der Sitzeinheit gegenüber der Basis mit der Relativbewegung des Schwenkträgers gegenüber der Sitzeinheit vorzugsweise wirkgekoppelt. Der Benutzer des erfindungsgemäßen Sitzmöbelstücks kann somit durch eine Verlagerung der Sitzeinheit gegenüber der Basis die Überführung der Beineinheit aus der Staustellung in die Nutzstellung bewirken. Vorzugsweise führt die Verlagerung der Sitzeinheit gegenüber der Basis nach vorne zur Überführung der Beineinheit in die Nutzstellung.Furthermore, it is considered to be particularly advantageous if the seat unit is designed to be displaceable relative to the base of the piece of seating furniture, as has already been explained in the introduction. In this case, the relative movement of the seat unit relative to the base with the relative movement of the pivot carrier relative to the seat unit is preferably operatively coupled. The user of the seat piece of furniture according to the invention can thus bring about the transfer of the leg unit from the stowed position to the use position by a displacement of the seat unit relative to the base. Preferably, the displacement of the seat unit relative to the base leads forward to the transfer of the leg unit into the use position.

Vorzugsweise arbeitet das Möbelstück dabei in Art einer Waage. Eine Bewegung der Sitzeinheit nach unten bewirkt dabei eine Bewegung der Beineinheit nach oben. Es wird also bei der Überführung der Beineinheit zwischen den Nutzzustand die potentielle Energie der jeweils abzusenkenden Einheit und der darauf ruhenden Körperpartie genutzt, um die andere Einheit und darauf ruhende Körperpartie anzuheben. Der Nutzer, der dabei auf dem Möbelstück sitzen bleibt, muss daher nur ein geringes Maß an mechanischer Energie durch Muskelkraft oder aber durch einen ggf. vorgesehenen Motor zur elektrischen Verlagerung zuführen.Preferably, the furniture works in the manner of a scale. A movement of the seat unit down causes a movement of the leg unit upwards. Thus, during the transfer of the leg unit between the use state, the potential energy of the unit to be lowered and of the body part resting thereon is used to raise the other unit and the body part resting thereon. The user, who remains sitting on the piece of furniture, therefore, has only a small Apply level of mechanical energy by muscle power or by a possibly provided motor for electrical displacement.

Es hat sich als besonders vorteilhaft herausgestellt, wenn die Beweglichkeit der Sitzeinheit gegenüber der Basis durch zwei Verlagerungshebel zur Verfügung gestellt wird, die jeweils um voneinander beabstandete Schwenkachse an der Basis und an der Sitzeinheit angelenkt sind. Die Verwendung zweiter Verlagerungshebel mit zueinander parallelen, jedoch voneinander beabstanden Schwenkachsen stellt eine baulich sehr einfache Möglichkeit zur Erzielung der Verlagerbarkeit der Sitzeinheit gegenüber der Basis zur Verfügung. Vorzugsweise sind dabei die Verlagerungshebel von verschiedener Länge, so dass im Zuge der Schwenkbewegung auch eine Verkippung der Sitzeinheit erfolgt. In der Nutzstellung der Beineinheit ist eine vordere Kante der Sitzfläche vorzugsweise angehoben. Vorzugsweise ist vorgesehen, dass die Schwenkwinkel der Verlagerungshebel zwischen Basis und Sitzeinheit stets kleiner als die Schwenkwinkel der Schwenkhebel zwischen Sitzeinheit und Zwischenträger sind. Vorzugsweise schwenken die Schwenkhebel zwischen dem Stauzustand und dem Nutzzustand um mehr als 80°, während die Verlagerungshebel um weniger als 60° verschwenken.It has been found to be particularly advantageous if the mobility of the seat unit relative to the base is provided by two displacement levers, which are each articulated about spaced pivot axis on the base and on the seat unit. The use of second displacement lever with mutually parallel, but spaced apart pivot axes provides a structurally very simple way to achieve the displaceability of the seat unit relative to the base available. Preferably, the displacement lever of different lengths, so that in the course of the pivoting movement, a tilting of the seat unit takes place. In the use position of the leg unit, a front edge of the seat is preferably raised. It is preferably provided that the pivot angle of the displacement lever between the base and seat unit are always smaller than the pivot angle of the pivot lever between the seat unit and intermediate carrier. Preferably, the pivot levers pivot between the jam state and the use state by more than 80 °, while the displacement levers pivot by less than 60 °.

Zur Erzielung einer stabilen Nutzstellung und/oder einer stabilen Staustellung der Beineinheit sind folgende Maßnahmen zweckmäßig; Wenn die Beineinheit sich in ihrer Staustellung unterhalb der Sitzeinheit befindet, befindet sich vorzugsweise mindestens einer der Verlagerungshebel oder Schwenkhebel nahe einer Totpunktlage oder sogar in einer Übertotpunktlage, so dass zur Überführung der Beineinheit in die Nutzstellung zunächst ein geringfügiges Anheben der Sitzeinheit zumindest im Bereich dieses in der Übertotpunktlage befindlichen Verlagerungshebels erforderlich. Alternativ oder zusätzlich kann ein Aktivierungshebel vorgesehen sein, der er ermöglicht, durch manuell aufgebrachte Muskelkraft die Totpunktlage zu verlassen.To achieve a stable use position and / or a stable stowed position of the leg unit, the following measures are expedient; When the leg unit is in its stowage position below the seat unit, preferably at least one of the displacement lever or pivot lever is near a dead center or even in an over-center position, so that for transferring the leg unit into the use position, first a slight lifting of the seat unit at least in the area of this in the Übertotpunktlage located shift lever required. Alternatively or additionally, an activation lever may be provided which allows him to leave the dead center by manually applied muscle power.

Ein versehentliches Bewirken der Überführung der Beineinheit in die Nutzstellung wird dadurch vermieden. Wenn die Beineinheit sich in ihrer Nutzstellung befindet, so ist vorzugsweise mindestens einer der Verlagerungshebel, vorzugsweise beide Verlagerungshebel, in einer Stellung, in der ein Winkel zwischen einer Verbindungsgeraden, die die Anlenkpunkte dieses Verlagerungshebels verbindet, einerseits und einer Horizontalebene andererseits vorzugsweise < 60°, insbesondere vorzugsweise < 50° ist. Hieraus resultiert, dass eine Verlagerung der Beineinheit aus der Nutzstellung in Richtung der Staustellung zunächst eine vergleichsweise starke Kraftbeaufschlagung der Beineinheit erfordert, welche üblicherweise nicht versehentlich bewirkt wird.Accidental effecting the transfer of the leg unit into the use position is thereby avoided. When the leg unit is in its use position, preferably at least one of the displacement levers, preferably both displacement levers, is in a position in which an angle between a connecting straight line connecting the articulation points of this displacement lever, on the one hand, and a horizontal plane, on the other hand, is preferably <60 °, especially preferably <50 °. This results in that a displacement of the leg unit from the use position in the direction of the stowed position initially requires a comparatively strong application of force to the leg unit, which is usually not accidentally effected.

Als vorteilhaft wird weiterhin angesehen, wenn eine Federeinrichtung am Sitzmöbelstück vorgesehen ist, die ausgehend von der Nutzstellung einer Überführung der Beineinheit in Richtung der Staustellung und/oder ausgehend von der Staustellung eine Überführung der Beineinheit in Richtung der Nutzstellung jeweils eine Gegenkraft entgegen setzt. Hierdurch wird die Stabilität der Staustellung bzw. der Nutzstellung erhöht.It is further considered to be advantageous if a spring device is provided on the piece of seating furniture, which, starting from the use position of a transfer of the leg unit in the direction of the stowage position and / or starting from the stowage position, respectively sets a transfer of the leg unit in the direction of the use position. As a result, the stability of the stowed position or the use position is increased.

Zur Erzielung der Wirkung, dass Nutzstellung und Staustellung stabilisiert werden, ist es von Vorteil, wenn die Federeinrichtung zwischen Anlenkpunkten an Teilkomponenten des Sitzmöbelstücks angeordnet ist, wobei diese Anlenkpunkte derart angeordnet sind, dass sie bei der Überführung der Beinauflage aus der Staustellung in die Nutzstellung zunächst voneinander beabstandet und anschließend einander angenähert werden.To achieve the effect that use position and stowed position are stabilized, it is advantageous if the spring device between articulation points on sub-components of the seating furniture piece is arranged, these articulation points are arranged such that they initially in the transfer position of the leg rest from the stowed position spaced apart and then approximated to each other.

Somit bedarf das Verlassen sowohl der Nutzstellung als auch der Staustellung der Zuführung mechanischer Energie in die Federeinrichtung.Thus, leaving both the use position and the stowed position of the supply of mechanical energy in the spring device requires.

Die Erfindung betrifft weiterhin ein Beschlagsystem für Sitzmöbelstücke, welches derart ausgebildet ist, dass es die genannte Relativbewegung zwischen einer Sitzeinheit einerseits und einer Baueinheit andererseits zur Verfügung stellt.The invention further relates to a fitting system for seating furniture pieces, which is designed such that it provides said relative movement between a seat unit on the one hand and a structural unit on the other hand.

Detaillierte Beschreibung des AusführungsbeispielsDetailed description of the embodiment

Fig. 1a zeigt ein erfindungsgemäßes Sitzmöbelstück 10, welches als gepolsterter Sessel ausgebildet ist. Fig. 1a shows an inventive piece of seating furniture 10, which is designed as a padded chair.

Dieses Sitzmöbelstück 10 verfügt über drei gegeneinander bewegliche und jeweils gepolsterte Einheiten, nämlich eine Sitzeinheit 12, eine Beineinheit 14 und eine Rückenlehneneinheit 16.This seating piece 10 has three mutually movable and respectively padded units, namely a seat unit 12, a leg unit 14 and a backrest unit 16.

Das Sitzmöbelstück 10 verfügt weiterhin über ein die Basis des Sitzmöbelstücks bildendes Basisgestell 18, welches in Fig. 1a gestrichelt dargestellt ist. Das Basisgestell 18 ist ortsfest zu einem Fußboden 1 und einer rückwärtig des Sitzmöbelstücks 10 befindlichen Wand 2 angeordnet. Das Sitzmöbelstück 10 weist einen Bewegungsmechanismus 20 auf, der durch den in Fig. 1b dargestellten Möbelbeschlag 22 verkörpert wird und welcher dem Zweck dient, die Relativbewegung der Sitzeinheit 12 sowie der Beineinheit 14 aus der Staustellung der Fig. 1a in die Nutzstellung der Fig. 3a zu gewährleisten.The seat piece of furniture 10 furthermore has a base frame 18 which forms the base of the piece of seating furniture and which is in Fig. 1a is shown in dashed lines. The base frame 18 is fixed to a floor 1 and a rear of the seat piece of furniture 10 located wall 2 is arranged. The seating furniture 10 has a moving mechanism 20, which is provided by the in Fig. 1b shown furniture fitting 22 is embodied and which serves the purpose of the relative movement of the seat unit 12 and the leg unit 14 from the stowed position of the Fig. 1a into the use of the Fig. 3a to ensure.

Anhand der Fig. 1b werden nachfolgend die Hauptkomponenten diese Möbelbeschlags 22 erläutert. Der Möbelbeschlag 22 verfügt über zwei Anbringungsleisten 24, welche fest mit dem Basisgestell 18 verbunden sind. Er verfügt weiterhin über einen vorliegend umlaufend geschlossen ausgebildeten Rahmen 26, welcher in nicht näher dargestellter Weise der Anbringung der Sitzeinheit 12 dient und welcher daher stets gemeinsam mit der Sitzeinheit 12 bewegt wird. Zur Anbringung der Beineinheit 14 verfügt der Beschlag 22 darüber hinaus über einen Schwenkträger 28, welcher stets ortsfest zur Beineinheit 14 verbleibt.Based on Fig. 1b The main components of this furniture fitting 22 will be explained below. The furniture fitting 22 has two mounting strips 24 which are fixedly connected to the base frame 18. He further has a present circumferentially closed formed frame 26, which serves in a manner not shown attaching the seat unit 12 and which is therefore always moved together with the seat unit 12. For attachment of the leg unit 14, the fitting 22 moreover has a pivot support 28, which always remains stationary relative to the leg unit 14.

Miteinander sind diese Komponenten wie nachfolgend erläutert verbunden. Einige nachfolgend erwähnte Teile des Beschlages 22 sind jeweils links- und rechtsseitig der Sitzfläche vorgesehen und zur übereinstimmenden Bewegung ausgebildet. Hier wird jeweils nur auf eine der Komponenten Bezug genommen.Together, these components are connected as explained below. Some of the following parts of the fitting 22 are each provided on the left and right sides of the seat and designed to coincide movement. Here, only one of the components is referred to.

Zwischen den basisfesten Anbringungsleisten 24 und dem sitzeinheitsfesten Rahmen 26 sind zwei Verlagerungshebel 32, 34 vorgesehen, die jeweils um eine basisseitige Schwenkachse 32a, 34a und jeweils um eine rahmenfeste Schwenkachse 32b, 34b verschwenkbar sind. Hierdurch ist die grundsätzliche Beweglichkeit der Sitzeinheit 12 gegenüber dem Basisgestell 18 gegeben, wobei durch die leicht voneinander abweichenden Hebellängen und/oder die Ausrichtung der Hebel in der Staustellung der Fig. 1a auch eine Kippbewegung der Sitzeinheit 12 gegenüber dem Basisgestell 18 im Zuge ihrer Bewegung erzwungen wird.Between the base-fixed mounting strips 24 and the seat-fixed frame 26, two displacement levers 32, 34 are provided which each about a base-side pivot axis 32a, 34a and in each case about a frame-fixed pivot axis 32b, 34b are pivotable. As a result, the basic mobility of the seat unit 12 relative to the base frame 18 is given, with the slightly different lever lengths and / or the orientation of the lever in the stowed position of the Fig. 1a Also, a tilting movement of the seat unit 12 relative to the base frame 18 is forced in the course of their movement.

Zwischen dem Rahmen 26 und einem unterhalb des Rahmens angeordneten Zwischenträger 30 sind zwei Schwenkhebel 36, 38 vorgesehen, wobei diese um ortsfest zueinander am Zwischenträger vorgesehene Schwenkachsen 36c, 38c und um ortsfest am Rahmen 26 vorgesehene Schwenkachsen 36b, 38b verschwenkbar sind. Somit ist auch zwischen dem Rahmen 26 und dem Zwischenträger 30 eine Zwangsführung vorgesehen. Der Zwischenträger 30 ist gegenüber dem Rahmen 26 nur entlang eines durch die Schwenkhebel 36, 38 vorgegebenen Bewegungspfad beweglich. Da die Hebel in etwa die gleiche Länge haben, erfolgt die Bewegung bei nur geringfügiger Verkippung des Zwischenträgers 30 gegenüber dem Rahmen 26.Between the frame 26 and an intermediate carrier 30 arranged below the frame, two pivoting levers 36, 38 are provided, wherein these swivel axles 36c, 38c, which are provided fixedly relative to one another on the intermediate carrier, and swivel axles 36b, 38b provided fixedly on the frame 26 are pivotable. Thus, a forced operation is also provided between the frame 26 and the intermediate carrier 30. The intermediate carrier 30 is movable relative to the frame 26 only along a movement path predetermined by the pivot levers 36, 38. Since the levers have approximately the same length, the movement takes place with only slight tilting of the intermediate carrier 30 relative to the frame 26.

Die Relativbewegung des Rahmens 26 gegenüber dem Basisgestell 18 sowie die Relativbewegung des Zwischenträgers 30 gegenüber dem Rahmen 26 sind miteinander wirkgekoppelt. Zu diesem Zweck ist ein Kopplungshebel 40 vorgesehen, welcher einerseits an einer Verlängerung des Verlagerungshebels 32 und andererseits am Schwenkhebel 38 schwenkbar angelenkt ist. Resultat ist, dass die Bewegung der Sitzeinheit 12 gegenüber dem Basisgestell 18 auch eine Bewegung des Zwischenträgers 30 gegenüber dem Rahmen 26 erzwingt. Dies wird im Weiteren noch erläutert.The relative movement of the frame 26 relative to the base frame 18 and the relative movement of the intermediate carrier 30 relative to the frame 26 are operatively coupled with each other. For this purpose, a coupling lever 40 is provided, which is articulated on the one hand on an extension of the displacement lever 32 and on the other hand on the pivot lever 38 pivotally. The result is that the movement of the seat unit 12 relative to the base frame 18 also forces a movement of the intermediate carrier 30 relative to the frame 26. This will be explained below.

Am Zwischenträger 30 ist weiterhin ein sich vom Zwischenträger 30 in Richtung einer Möbellängsachse 4 nach vorne erstreckender Fortsatz 42 vorgesehen, welcher über seine überwiegende Länge als Hohlrohr ausgebildet ist. Am Ende dieses Fortsatzes 42 schließt sich ein U-förmiger Endabschnitt 44 an, in dessen beiden als Blechflächen ausgebildeten U-Schenkeln jeweils eine Kulissenbahn 44a vorgesehen ist. Innerhalb des als Hohlrohrs ausgebildeten Fortsatzes 42 ist ein Schiebeglied 46 vorgesehen, welches im Hohlraum des Hohlrohrs 42 verschieblich ist. Am distalen Ende dieses Schiebeglieds 46 ist um eine Schwenkachse 48 schwenkbar der bereits genannte Schwenkträger 28 angelenkt. An den Seiten weist dieser Schwenkträger 28 Kulissengleiter 28a auf, welche sich bis in die Kulissenbahnen 44a erstrecken. Eine Relativverschiebung des Schiebeglieds 46 gegenüber dem Hohlrohr 42 führt dazu, dass die Kulissensteine 28a entlang der Kulissenbahn 44a verschoben werden und dadurch eine Schwenkbewegung des Schwenkträgers 28 gegenüber dem Hohlrohr 42 und dem Schiebeglied 46 bewirken.On the intermediate support 30 is further extending from the intermediate carrier 30 in the direction of a furniture longitudinal axis 4 forward extension 42 is provided, which is formed over its vast length as a hollow tube. At the end of this extension 42, a U-shaped end portion 44 connects, in each of which two U-legs formed as sheet metal surfaces, a slide track 44a is provided. Within the extension 42 formed as a hollow tube, a sliding member 46 is provided, which is displaceable in the cavity of the hollow tube 42. At the distal end of this sliding member 46 is pivotally about a pivot axis 48 of the already mentioned pivot carrier 28 is articulated. On the sides of this pivot support 28 link slider 28a, which extend into the slide tracks 44a. A relative displacement of the sliding member 46 relative to the hollow tube 42 causes the sliding blocks 28a to be displaced along the slide track 44a and thereby cause a pivoting movement of the pivot carrier 28 relative to the hollow tube 42 and the sliding member 46.

Um das Schiebeglied 46 innerhalb des Hohlrohrs verlagern zu können, ist ein Steuerhebel 50 vorgesehen. Dieser Steuerhebel ist um eine Schwenkachse 52 schwenkbar am Zwischenträger 30 angelenkt. Seine beiden gegenüberliegenden Enden sind zum einen an einer die Schwenkhebel 36 verbindenden Verbindungsstange 36d und andererseits über einen Zwischenhebel 54 am Schiebeglied 46 angelenkt.In order to shift the slide member 46 within the hollow tube, a control lever 50 is provided. This control lever is pivoted about a pivot axis 52 pivotally mounted on the intermediate carrier 30. Its two opposite ends are articulated on one hand to a pivot lever 36 connecting the connecting rod 36 d and on the other hand via an intermediate lever 54 on the sliding member 46.

Der Zwischenhebel 54 wirkt dabei als Ausgleichselement und gestattet es, durch ein Verschwenken des Steuerhebels 50 um die Schwenkachse 52 das Schiebeglied 46 tiefer in den als Hohlrohr ausgebildeten Fortsatz 42 hinein zu schieben bzw. aus diesem herauszuziehen.The intermediate lever 54 acts as a compensating element and makes it possible, by pivoting the control lever 50 about the pivot axis 52, the sliding member 46 deeper into the extension formed as a hollow tube 42 to push in or out of this.

Somit ist ein Bewegungsmechanismus zur Verfügung gestellt, der eine vollständige Wirkkopplung zwischen all seinen Komponenten umfasst. Durch die vom Benutzer beeinflusste Relativstellung der Sitzeinheit 12 gegenüber dem Basisgestell 18 wird die Anordnung aller anderen Komponenten des Möbelbeschlages 22 bestimmt.Thus, a moving mechanism is provided which includes full active coupling between all its components. By the user-influenced relative position of the seat unit 12th relative to the base frame 18, the arrangement of all other components of the furniture fitting 22 is determined.

Nach dieser Darlegung der Einzelkomponenten des Ausführungsbeispiels des erfindungsgemäßen Sitzmöbelstückes wird anschließend die Überführung aus dem Nutzzustand der Fig. 1a bis 1c in den Nutzzustand der Fig. 3a bis 3c erläutert.After this presentation of the individual components of the embodiment of the seating furniture piece according to the invention then the transfer from the use state of Fig. 1a to 1c in the state of use of Fig. 3a to 3c explained.

Im Ausgangszustand der Figuren 1a bis 1c, in welchem sich die Beineinheit 14 unterhalb der Sitzeinheit 12 befindet, hat das Möbelstück die Funktion und Anmutung eines einfachen Sessels. Der Verlagerungshebel 34 erstreckt sich in diesem Zustand weitgehend vertikal, so dass ein rückwärtiges Ende der Sitzfläche 12a seine denkbar höchste Stellung einnimmt. Der vordere Verlagerungshebel 32 befindet sich dagegen in dieser Ausgangsstellung in einer Übertotpunktlage und ist gegenüber der Vertikalen angewinkelt. Um die Beineinheit 14 zu verlagern ist es ausgehend von Figur 1a erforderlich, den vorderen Verlagerungshebel 32 bezogen auf die Perspektive der Figur 1a im Uhrzeigersinn zu verschwenken. Da dies mit einem Anheben eines vorderen Teils der Sitzeinheit 12 einhergeht, auf der das Gewicht des Sitzenden ruht, ist eine ungewollte Verlagerung der Beineinheit 14 nicht zu befürchten. Die Stabilität der Ausgangsstellung wird weiterhin durch eine Feder 56 verstärkt, welche an den Schwenkhebeln 36, 38 angelenkt ist und welche bei einer Verlagerung der Sitzeinheit 12 gegenüber dem Basisgestell 18 gestreckt würde.In the initial state of FIGS. 1a to 1c in which the leg unit 14 is located below the seat unit 12, the piece of furniture has the function and appearance of a simple chair. The displacement lever 34 extends in this state largely vertically, so that a rear end of the seat 12 a assumes its highest possible position. The front displacement lever 32, however, is in this starting position in an over-center position and is angled relative to the vertical. To relocate the leg unit 14, it is based on FIG. 1a required, the front displacement lever 32 with respect to the perspective of FIG. 1a to turn clockwise. Since this is accompanied by a lifting of a front part of the seat unit 12, on which the weight of the seated person rests, an unintentional displacement of the leg unit 14 is not to be feared. The stability of the starting position is further enhanced by a spring 56, which is articulated on the pivot levers 36, 38 and which would be stretched in a displacement of the seat unit 12 relative to the base frame 18.

Um dennoch eine Überführung des Sitzmöbelstücks 10 in den Zustand der Figur 3c zu erzielen, muss der Benutzer zunächst die Übertodlage des Verlagerungshebels 32 überwinden. Er tut dies vorzugsweise, indem er sich beispielsweise an der Rückeinheit 16 abstützt und die Sitzeinheit 12 soweit nach vorne verlagert, dass der Verlagerungshebel 32 über die Vertikale hinaus verschwenkt wird. Ähnliches ist auch durch einen nicht dargestellten Aktivierungshebel zu erzielen, der bei Betätigung diese Bewegung ermöglicht und einen Anfangsschub für die Überführung erzeugt. Hierdurch kann insbesondere auch die in der Ausgangslage gegenüber dem Schwenkhebel 38 nahezu gegebene Totpunktlage des Kopplungshebels 40 überwunden werden.Nevertheless, a transfer of the piece of seating furniture 10 in the state of Figure 3c To achieve, the user must first overcome the Übertodlage the shift lever 32. It preferably does this by supporting itself, for example, on the rear unit 16 and displacing the seat unit 12 so far forward that the displacement lever 32 is pivoted beyond the vertical. The same is also true to achieve an activation lever, not shown, which enables this movement when actuated and generates an initial thrust for the transfer. In this way, in particular, the dead center position of the coupling lever 40, which is almost given in the starting position relative to the pivoting lever 38, can be overcome.

Der so erreichte Zwischenzustand ist in Figur 2a dargestellt. Durch die Koppelung des vorderen Verlagerungshebels 32 mit dem hinteren Schwenkhebel 38 über den Steuerhebel 40 führt diese Verlagerung der Sitzeinheit 12 gleichzeitig zu einer Verlagerung der Beineinheit 14 gegenüber der Sitzeinheit 12. Diese wird, geführt primär durch die Schwenkhebel 36, 38 weitgehend verschwenkungsfrei nach vorne verlagert. Die Verlagerung ist jedoch nicht auf jenes Maß beschränkt, welches sich durch die Schwenkhebel 36, 38 ergibt und um das der Zwischenträger 30 verlagert wird. Stattdessen wird aufgrund der Wirkkopplung des Schiebeglieds 46 mit dem Zwischenträger 30 und dem Schwenkhebel 36 über den Steuerhebel 50 auch eine zusätzliche Verlagerung des Schiebeglieds 46 erzielt. Dieses wird tiefer in das den genannten Fortsatz bildende Hohlrohr 42 eingeschoben, wobei es vorzugsweise durch hierfür vorgesehene Rollen leichtgängig in diesem beweglich ist. Am gegenüberliegenden Ende wird dadurch der Schwenkträger 28, an dem die Beineinheit 40 befestigt ist, zusätzlich gegenüber dem Basisgestellt 18 in Möbellängsrichtung 4 verlagert. Da die Gleitsteine 28a, die auch als auch Rollen ausgebildet sein können, hierdurch in den Kulissenführungen 44a verschoben werden, kommt es gleichzeitig zu einer Schwenkbewegung des Schwenkträgers 28.The intermediate state reached in this way is in FIG. 2a shown. By the coupling of the front displacement lever 32 with the rear pivot lever 38 via the control lever 40, this displacement of the seat unit 12 simultaneously leads to a displacement of the leg unit 14 relative to the seat unit 12. This is, guided primarily by the pivot lever 36, 38 largely pivoted forward displaced , However, the displacement is not limited to that amount which results from the pivot lever 36, 38 and is displaced by the intermediate carrier 30. Instead, an additional displacement of the sliding member 46 is achieved due to the active coupling of the sliding member 46 with the intermediate carrier 30 and the pivot lever 36 via the control lever 50. This is pushed deeper into the said extension hollow tube 42, wherein it is preferably by this provided rollers easily in this movable. At the opposite end, the pivot support 28, to which the leg unit 40 is fastened, is additionally displaced in relation to the base position 18 in the longitudinal direction 4 of the furniture. Since the sliding blocks 28a, which may also be designed as rollers, are thereby displaced in the slide guides 44a, pivotal movement of the pivot carrier 28 occurs at the same time.

Bei fortgesetzter Bewegung wird der Zustand der Figuren 3a bis 3c erreicht. Durch die Kreisbahn, auf der der Zwischenträger 30 bewegt wird, wird die Beineinheit 14 gegen Ende der Relativbewegung gegenüber der Sitzeinheit 12 angehoben, so dass die Beinauflagefläche 14a an der Oberfläche der Beineinheit 14 gegen Ende der Bewegung in etwa auf gleicher Höhe wie die Sitzfläche 12a angeordnet ist. Dieses Anheben der Beineinheit 14 in der letzten Bewegungsphase wird auch durch ein leichtes Verschwenken des Fortsatzes 42 in Folge der Auslegung der leicht voneinander abweichenden Längen der Hebel 36, 38 erzielt, wobei zur Kompensation dieser Schwenkbewegung eine entsprechende Formgebung der Kulissenbahnen 44a vorgesehen ist, so dass in der ersichtlichen Weise die Schwenkbewegung der Beineinheit 14 gegenüber dem Boden 1 in der letzten Phase der Bewegung vernachlässigbar klein ist.With continued movement, the state of the FIGS. 3a to 3c reached. By the circular path on which the intermediate carrier 30 is moved, the leg unit 14 is raised toward the end of the relative movement relative to the seat unit 12, so that the leg support surface 14a on the surface of the leg unit 14 approximately at the end of the movement the same height as the seat 12a is arranged. This lifting of the leg unit 14 in the last phase of motion is also achieved by a slight pivoting of the extension 42 as a result of the interpretation of slightly different lengths of the levers 36, 38, to compensate for this pivotal movement a corresponding shape of the slide tracks 44a is provided, so that in the apparent manner, the pivotal movement of the leg unit 14 relative to the bottom 1 in the last phase of the movement is negligibly small.

Die somit erzielbare Nutzstellung der Beineinheit 14, die in Figur 3a dargestellt ist, ist ebenso wie die Ausgangsstellung der Figur 1a sehr stabil. Aufgrund der Winkel α1, α2 der Verlagerungshebel 32, 34 von etwa 40° bis 45°, die diese im Zustand der Figur 3a einnehmen, ist eine Rücküberführung der Beineinheit 14 in den Zustand der Figur 1a in einer ersten Bewegungsphase zunächst damit verbunden, dass die Sitzeinheit 12 in erheblichem Maße angehoben werden muss. Da auf der Sitzfläche zu diesem Zeitpunkt jedoch ein Benutzer sitzt, ist nicht zu befürchten, dass die Last seiner Beine ausreichend ist, um den Nutzzustand der Figur 3a unwillentlich aufzuheben.The thus achievable use position of the leg unit 14, the in FIG. 3a is shown as well as the starting position of the FIG. 1a very stable. Due to the angle α1, α2 of the displacement lever 32, 34 of about 40 ° to 45 °, this in the state of FIG. 3a is a return transfer of the leg unit 14 in the state of FIG. 1a in a first phase of movement initially associated with the fact that the seat unit 12 must be raised to a considerable extent. However, since a user is sitting on the seat at this time, there is no reason to fear that the load on his legs will be sufficient to reduce the working condition of the user FIG. 3a unintentionally cancel.

Die Verlagerung der Sitzeinheit 12 vom Ausgangszustand der Figur 1a bis in die Stellung der Figur 3a ermöglicht darüber hinaus in der skizzierten Weise, dass die Rückenlehneneinheit 16 bis in eine Komfortstellung verschwenken kann, ohne dass sie hierbei in Berührkontakt mit der Wand 2 gelangt. Dies wird durch die Verlagerung der Sitzeinheit 14 erzielt. The displacement of the seat unit 12 from the initial state of FIG. 1a to the position of FIG. 3a Moreover, in the manner outlined, the backrest unit 16 can pivot into a comfort position without it coming into contact with the wall 2. This is achieved by the displacement of the seat unit 14.
