Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Sitzmöbel zu verbessern.Object of the present invention is to improve a generic seating.
Dies wird mit einem Sitzmöbel mit den Merkmalen des Patentanspruchs 1 erreicht.This is achieved with a chair with the features of
Wie der Stand der Technik besitzt das Sitzmöbel einen Support, zumindest eine Sitzplatte und zumindest eine an mindestens einem Trägerarm angeordneten Rückenlehne. Die Sitzplatte ist an mindestens einer mit dem Trägerarm verbundenen längserstreckten Biegefeder abgestützt. Die Biegefeder ist so angeordnet, dass sie bei Belastung der Sitzplatte transversal zu ihrer Längserstreckung elastisch auslenkbar ist.As in the prior art, the seating furniture has a support, at least one seat panel and at least one backrest arranged on at least one support arm. The seat plate is supported on at least one longitudinally extending bending spring connected to the carrier arm. The bending spring is arranged so that it is elastically deflectable when loaded the seat plate transversely to its longitudinal extent.
Es ist eine drehfeste Fixierung der Biegefeder am Trägerarm vorgesehen, also eine direkte Verbindung von Biegefeder und Trägerarm ohne Zwischenschaltung von Dreh- oder Schwenkgelenken oder anderen, eine Relativbewegung zwischen Biegefeder und Trägerarm zulassenden Bauteilen. Es sind dadurch die mit den Dreh- oder Schwenkgelenken verbundenen Dreh- oder Schwenkachsen und deren Führungen zwischen Biegefeder und Trägerarm eingespart, was zu einer einfachen Konstruktion führt. Im Zuge der Erfindung wurde überraschenderweise festgestellt, dass trotz dieser einfachen Konstruktion die Herstellung eines Sitzmöbels mit guter Ergonomie und Synchronmechanik möglich ist.It is a non-rotatable fixation of the spiral spring provided on the support arm, ie a direct connection of spiral spring and support arm without the interposition of rotary or pivot joints or other, a relative movement between bending spring and support arm allowing components. There are thereby associated with the rotary or pivot joints pivot or pivot axes and their guides between bending spring and carrier arm saved, resulting in a simple construction. In the course of the invention was surprisingly found that despite this simple construction, the production of a chair with good ergonomics and synchronous mechanism is possible.
Die transversal, also quer zu ihrer Längserstreckung auslenkbare Biegefeder weist eine größere Elastizität als der Trägerarm auf. Dies bedeutet, dass die Biegefeder bei gleichem Drehmoment stärker elastisch ausgelenkt wird als der Trägerarm und somit die Elastizität der dadurch gebildeten Mechanik im Wesentlichen durch die Biegefeder bereitgestellt wird.The transverse spring, that is to say deflectable transversely to its longitudinal extent, has a greater elasticity than the carrier arm. This means that the bending spring is deflected more elastically with the same torque than the carrier arm and thus the elasticity of the mechanism formed thereby is provided essentially by the spiral spring.
Wenn auch der Trägerarm und die Biegefeder einstückig, also in Form eines im Wesentlichen durchgehenden Bauteils ausgeführt sein können, so ist in einer Ausgestaltungsformen der Erfindung vorgesehen, dass der Trägerarm und die Biegefeder als jeweils eigenständige Bauteile ausgeführt sind, welche dann miteinander in einem Verbindungsbereich verbunden werden. Bevorzugt sind hierbei lösbare Verbindungen, wie z. B. Verschraubungen oder Vernietungen. Es kann aber auch das Verkleben von Biegefeder und Trägerarmen im Verbindungsbereich o. dgl. vorgesehen sein. Vorteil dieser Varianten der Erfindung ist es, dass das Material, aus dem der Trägerarm gefertigt wird, vollkommen unabhängig von dem für die Biegefeder benötigten Material ausgesucht werden kann. Wählt man diese Ausgestaltungsform, so können für den Trägerarm auch im Wesentlichen steife Materialien herangezogen werden. Die Biegefeder kann in diesen Fällen z. B. als Blattfeder oder als Blattfederpaket ausgebildet sein. Die Sitzplatte stützt sich dabei vorzugsweise im Bereich ihrer der Rückenlehne abgewandten Hälfte, vorzugsweise im Bereich ihres der Rückenlehne entferntesten Drittels, an der Biegefeder ab.Although the carrier arm and the bending spring can be made in one piece, ie in the form of a substantially continuous component, in one embodiment of the invention it is provided that the carrier arm and the bending spring are each designed as separate components, which are then connected to one another in a connection region become. Preference is given to releasable compounds such. B. screwing or riveting. But it can also be the bonding of spiral spring and support arms in the connection area o. The like. Be provided. Advantage of these variants of the invention is that the material from which the support arm is made, can be selected completely independent of the material required for the bending spring. If one chooses this embodiment, substantially stiff materials can also be used for the support arm. The spiral spring can in these cases z. B. as a leaf spring or as Be formed leaf spring package. The seat plate is supported preferably in the region of its half facing away from the backrest, preferably in the region of the backrest farthest third, on the spiral spring from.
Eine Lagereinrichtung besteht beispielsweise aus einer Welle an der Sitzplatte und einem Langloch in der Sitzplatte oder einem zum einem Support gehörenden Trägergehäuse für die Sitzplatte. Das Langloch lässt eine Relativbewegung zwischen der Sitzplatte und dem Support mit einer in Betriebsstellung des Sitzmöbels vertikalen Komponente zu. Die Sitzplatte kann sich an der Biegefeder, nämlich an deren dem Trägerarm entgegengesetzten freien Ende, direkt oder indirekt abstützen. Bei einer indirekten Abstützung schlägt die Biegefeder an die Lagereinrichtung an und das Langloch ist im Trägergehäuse ausgebildet. Bei direkter Abstützung schlägt die Sitzplatte an der Biegefeder an und das Langloch, in dem die Welle beweglich gelagert ist, ist in der Sitzplatte ausgebildet. Bei dieser vertikalen Komponente der Relativbewegung zwischen Sitzplatte und Support wird die Biegefeder gespannt, wenn die Sitzplatte belastet wird, und entspannt, wenn die Sitzplatte entlastet wird. Es ist eine Abstützung der Sitzplatte auf der Biegefeder vorgesehen, die auch eine Relativbewegung zwischen Sitzplatte und Biegefeder mit einer in Betriebsstellung des Sitzmöbels horizontalen Komponente zulässt. Die für eine Synchronmechanik mit drei Gelenkpunkten notwendige horizontale Relativbewegung kann jedem der drei Gelenkpunkte verwirklicht sein. Um eine kontrollierte Synchronbewegung in vordefinierten Grenzen sicherzustellen, weist diese Lagereinrichtung günstigerweise Anschläge auf, die die Relativbewegung zwischen Biegefeder und Sitzplatte in vertikaler Richtung begrenzen. Entsprechende Anschläge zur Begrenzung der horizontalen Relativbewegung sind ebenfalls zweckmässig.A bearing device consists for example of a shaft on the seat plate and a slot in the seat plate or belonging to a support carrier housing for the seat plate. The slot allows a relative movement between the seat plate and the support with a vertical position in the operating position of the chair. The seat plate can be supported directly or indirectly on the bending spring, namely on its free end opposite the support arm. In an indirect support, the spiral spring strikes the bearing device and the slot is formed in the carrier housing. In direct support, the seat plate strikes against the spiral spring and the slot in which the shaft is movably mounted, is formed in the seat plate. In this vertical component of the relative movement between the seat plate and the support, the bending spring is tensioned when the seat plate is loaded, and relaxed when the seat plate is relieved. It is provided a support of the seat plate on the bending spring, which also allows a relative movement between the seat plate and bending spring with a horizontal position in the operating position of the chair. The horizontal relative movement necessary for a synchronous mechanism with three articulation points can be realized for each of the three articulation points. In order to ensure a controlled synchronous movement in predefined limits, this bearing device favorably has stops which limit the relative movement between the spiral spring and the seat plate in the vertical direction. Corresponding stops for limiting the horizontal relative movement are also expedient.
Eine einfache Ausführungsform der Lagereinrichtung zur Ermöglichung der vertikalen Relativbewegung zwischen Sitzplatte (zusammen mit dem freiem Ende der Blattfeder) und Support weist zumindest ein Langloch auf. Soll auch die horizontale Relativbewegung zwischen dem freien Ende der Biegefeder und der Sitzplatte erlaubt sein, sind zwei in einem von 0° abweichenden Winkel zueinander angeordnete Langlöcher vorgesehen.A simple embodiment of the bearing device for enabling the vertical relative movement between the seat plate (together with the free end of the leaf spring) and support has at least one slot. If the horizontal relative movement between the free end of the spiral spring and the seat plate is also to be allowed, two oblong holes arranged at an angle deviating from 0 ° are provided.
In den Langlöchern für vertikale und horizontale Relativbewegungen ist eine Welle verschiebbar gelagert. Es ist vorzugsweise diese Welle, die sich im Bereich des freien Endes der Biegefeder auf dieser abstützt. Im Fall von zwei Langlöchern sind diese vorteilhaft im Wesentlichen senkrecht zueinander angeordnet.In the oblong holes for vertical and horizontal relative movements, a shaft is slidably mounted. It is preferably this wave, which is supported in the region of the free end of the spiral spring on this. In the case of two oblong holes, these are advantageously arranged substantially perpendicular to one another.
Es kann der Trägerarm und/oder die Biegefeder aus Kunststoff gefertigt sein, wobei dieser Kunststoff vorzugsweise zumindest partiell faserverstärkt ist. Bevorzugt weisen der Trägerarm und/oder die Biegefeder, vorzugsweise jeweils über ihre im Wesentlichen gesamte Länge, einen Kernbereich mit faserverstärktem Kunststoff auf, der umgeben ist von einem Mantelbereich mit Kunststoff ohne Faserverstärkung. Diese Ausführung erlaubt eine einstückige Konstruktion von Trägerarm und Biegefeder, so dass diese zusammen ein im Wesentlichen durchgehendes Bauteil bilden.It can be made of plastic, the support arm and / or the bending spring, wherein this plastic is preferably at least partially fiber reinforced. Preferably, the support arm and / or the bending spring, preferably in each case over its substantially entire length, a core region with fiber-reinforced plastic, which is surrounded by a cladding region with plastic without fiber reinforcement. This embodiment allows a one-piece construction of the carrier arm and bending spring, so that together they form a substantially continuous component.
Um einen steiferen Trägerarm und eine elastischere Biegefeder zu erhalten, kann die Biegefeder einen geringeren Querschnitt und/oder eine andere Materialzusammensetzung als der Trägerarm aufweisen.In order to obtain a stiffer arm and a more elastic bending spring, the spiral spring may have a smaller cross-section and / or a different material composition than the support arm.
Bei einer Alternative, bei der die Biegefeder am Trägerarm angeschraubt und/oder angenietet und/oder angeklebt ist, kann für jedes dieser Teile ein geeignetes Material verwendet werden. So kann insbesondere die Biegefeder eine Blattfeder oder ein Blattfederpaket sein.In an alternative in which the spiral spring is screwed to the support arm and / or riveted and / or glued, a suitable material can be used for each of these parts. Thus, in particular, the bending spring may be a leaf spring or a leaf spring package.
Um eine Synchronmechanik verwirklichen zu können ist der Trägerarm zusammen mit der Biegefeder an der Sitzplatte, vorzugsweise an der Unterseite der Sitzplatte, über zumindest eine in Betriebsstellung des Sitzmöbels im Wesentlichen horizontale Sitzplattenschwenkachse schwenkbar angelenkt ist. Die Sitzplattenschwenkachse ist drehbar an der Sitzplatte und/oder dem Trägerarm und/oder der Biegefeder angeordnet. Sie kann ansonsten ortsfest daran angeordnet sein, oder aber eine Verschiebung in vorzugsweise horizontaler Richtung zwischen Sitzplatte und Trägerarm/Biegefeder erlauben.In order to be able to realize a synchronous mechanism, the carrier arm together with the bending spring on the seat plate, preferably on the underside of the seat plate, is articulated via at least one in the operating position of the seat substantially horizontal seat plate pivot axis. The seat plate pivot axis is rotatably arranged on the seat plate and / or the support arm and / or the bending spring. It may otherwise be arranged stationary thereto, or allow a displacement in a preferably horizontal direction between the seat plate and the support arm / bending spring.
Die Sitzplattenschwenkachse ist im Bereich der der Rückenlehne nächsten Hälfte der Sitzplatte, vorzugsweise im Bereich des der Rückenlehne nächsten Drittels der Sitzplatte, an dieser angeordnet, um eine angenehme Synchronbewegung zwischen Sitzneigung und Rückenlehnenneigung zu erreichen. Der Trägerarm und die Biegefeder sind zusammen über zumindest eine in Betriebsstellung des Sitzmöbels im Wesentlichen horizontale Trägergehäuseschwenkachse an einem mit einem Untergestell oder Support verbundenen Trägergehäuse schwenkbar angelenkt. Auch in diesem Anlenkpunkt kann die Trägergehäuseschwenkachse in horizontaler Richtung verschieblich gegenüber Trägerarm/Biegefeder oder gegenüber dem Trägergehäuse gelagert sein. Die Trägergehäuseschwenkachse ist bevorzugt gegebenenfalls drehbar aber ansonsten ortsfest an dem Trägergehäuse und/oder dem Trägerarm und/oder der Biegefeder angeordnet.The seat plate pivot axis is in the region of the backrest next half of the seat plate, preferably in the region of the backrest next third of the seat plate, arranged thereon, in order to achieve a pleasant synchronous movement between the seat tilt and backrest tilt. The support arm and the bending spring are articulated together via at least one in the operating position of the chair substantially horizontal Trägergehäuseschwenkachse on a connected to a base frame or support carrier housing pivotally. Also in this point of articulation, the carrier housing pivot axis can be mounted displaceably in the horizontal direction with respect to the carrier arm / bending spring or with respect to the carrier housing. The carrier housing pivot axis is preferably optionally rotatable but otherwise fixedly arranged on the carrier housing and / or the carrier arm and / or the bending spring.
Ein Support bildet ein tragendes Untergestell. Er weist einen Standfuss, eine Säule und ein Trägergehäuse auf, wobei der Standfuss über die Säule mit dem Trägergehäuse verbundenen ist und vorzugsweise um eine in Betriebsstellung des Sitzmöbels vertikale Achse gegenüber dem Trägergehäuse drehbar ist. Zweckmässigerweise ist das Trägergehäuse gegenüber der Säule nicht kippbar. Es ist daher keine in Betriebsstellung des Sitzmöbels horizontale Achse zwischen dem Trägergehäuse und dem Standfuss ausgebildet.A support forms a supporting base. It has a pedestal, a column and a carrier housing, wherein the stand is connected via the column to the carrier housing and is preferably rotatable about a vertical axis in the operating position of the seat relative to the carrier housing. Conveniently, the carrier housing with respect to the column is not tilted. It is therefore not formed in the operating position of the seat horizontal axis between the support housing and the stand.
Der Trägerarm ist vorzugsweise zumindest bereichsweise als Trägerarmpaar ausgebildet, an welchem drehfest fixierte Biegefedern angeordnet sind.The support arm is preferably formed at least in regions as a pair of carrier arms, on which rotationally fixed fixed bending springs are arranged.
Die erfindungsgemäße drehfeste Fixierung der Biegefeder am Trägerarm kann in ihren verschiedenen Ausgestaltungsformen besonders bevorzugt bei der Herstellung von Stühlen, Bürostühlen und insbesondere bei sogenannten Drehstühlen mit einer um eine vertikale Achse drehbaren Sitzplatte umgesetzt werden.The inventive non-rotatable fixation of the spiral spring on the support arm can be implemented in its various embodiments particularly preferred in the manufacture of chairs, office chairs and especially in so-called swivel chairs with a rotatable about a vertical axis seat plate.
Es ist mit Vorteil, und dies gerade bei Bürostühlen, eine Einstellung einer Vorspannung der Biegefeder vorgesehen. Diese Vorspannung kann in der Lagereinrichtung in einfacher Weise verwirklicht werden, indem die Welle drehbar ausgebildet ist und im Bereich der Biegefeder mit einem Exzenter ausgerüstet ist. Durch drehen der Welle wird damit die Biegefeder der Exzentrizität des Exzenters entsprechend vorgespannt. Es sind vorzugsweise drei Stellungen des Exzenters vorgesehen, in denen dieser einrastet.It is advantageous, and this is especially provided in office chairs, a setting of a bias of the bending spring. This bias can be realized in the storage device in a simple manner by the shaft is rotatable and is equipped in the region of the bending spring with an eccentric. By rotating the shaft so that the bending spring of the eccentricity of the eccentric is biased accordingly. There are preferably provided three positions of the eccentric in which it engages.

Die Sitzplattenschwenkachse 14 ist günstigerweise in dem Sinne ortsfest an der Sitzplatte 1 und/oder dem Trägerarm 3 und/oder der Biegefeder 4 angeordnet, als dass sie weder in horizontaler noch in vertikaler Richtung gegenüber den genannten Bauteilen verschoben werden kann. Die Position der Sitzplattenschwenkachse 14 liegt, in horizontaler Richtung gesehen, günstigerweise im Bereich der der Rückenlehne 2 zugewandten Hälfte der Sitzplatte 1, bevorzugt im Bereich des der Rückenlehne 2 nächsten Drittels der Sitzplatte 1.The
Das zweite Schwenkgelenk wird durch die bereits erwähnte Trägergehäuseschwenkachse 15 gebildet. Mit dieser ist der Trägerarm 3 in unmittelbarer Nähe zur Säule 18 am Trägergehäuse 17 angelenkt. Auch diese Schwenkachse 15 ist in den gezeigten Ausführungsformen weder in horizontaler noch in vertikaler Richtung gegenüber dem Trägergehäuse 17 und dem Trägerarm 3 verschiebbar. Ihre Lage ist, in der Horizontalen gesehen, zwischen der Sitzplattenschwenkachse 14 und der Lagereinrichtung 6. Über die Lagereinrichtung 6 stützt sich die Sitzplatte 1 mit ihrer von der Rückenlehne 2 abgewandten Vorderseite auf der Biegefeder 4 in dem Bereich des freien Endes 5 der Biegefeder 4 ab. Dieser Bereich des freien Endes 5 wird bevorzugt durch die vordersten 10 bis 15% der längserstreckten Biegefeder 4 gebildet. Der vordere Bereich der Sitzplatte 1, in dem sich dieser auf der Biegefeder 4 abstützt, liegt günstigerweise, in horizontaler Richtung gesehen, in der der Rückenlehne 2 abgewandten Hälfte der Sitzplatte 1, vorzugsweise im Bereich ihres der Rückenlehne 2 entferntest angeordneten Drittels. Die Lagereinrichtung 6, mit der sich die Sitzplatte 1 auf der Biegefeder 4 abstützt, ermöglicht eine Relativbewegung zwischen Sitzplatte 1 und Biegefeder 4 sowohl in horizontaler, als auch in vertikaler Richtung. Um definierte Bewegungsgrenzen sicherzustellen, ist die Relativbewegung aber sowohl in vertikaler als auch in horizontaler Richtung durch Anschläge 7, 8 begrenzt. In den gezeigten drei Ausführungsbeispielen werden diese Relativbewegungen in horizontaler und vertikaler Richtung durch zwei Langlöcher 9, 10 ermöglicht. Dabei ist, wie besonders gut in der Explosionsdarstellung der
Es müssen auch nicht zwingend Langlöcher zur Begrenzung vorgesehen sein. Auch anderweitig ausgebildete Anschläge und Gleitflächen oder Führungen sind möglich.It also does not necessarily have to be provided oblong holes to limit. Also trained attacks and sliding surfaces or guides are possible.
