Description

Die Erfindung betrifft ein Tragelement für ein Sitzmöbel, insbesondere für einen Bürostuhl, wobei das Sitzmöbel ein Sitzteil mit einem Anschlusselement aufweist und das Tragelement ein Fußteil aufweist. Außerdem betrifft die Erfindung ein Sitzmöbel, insbesondere einen Bürostuhl, mit dem Tragelement.The invention relates to a support element for a chair, in particular for an office chair, wherein the seat has a seat part with a connection element and the support element has a foot part. Moreover, the invention relates to a chair, in particular an office chair, with the support element.

Bei Personen, die viel Zeit im Sitzen verbringen, kommt es auf Grund fehlender Bewegung häufig zu einer Degeneration der Rückenmuskulatur und zu Haltungsschäden. Daraus resultieren Rückenschmerzen und unter Umständen ernsthafte gesundheitliche Probleme. Davon besonders betroffen sind Personen, die beruflich eine Tätigkeit im Sitzen ausüben. Durch die Beschäftigung, zum Beispiel an einem Computer, wird nicht durchgehend eine bewusste Sitzposition eingenommen. Zudem ist die Beweglichkeit herkömmlicher Bürostühle im Wesentlichen auf die Höhenverstellung mittels einer Gasfeder und die Federung der Rückenlehne beschränkt. Ein dynamisches Sitzen ist nur sehr begrenzt möglich.For people who spend a lot of time sitting, there is often due to lack of movement to a degeneration of the back muscles and posture damage. This results in back pain and may cause serious health problems. Particularly affected are people who work in a sitting position. Employment, for example on a computer, does not consistently occupy a conscious sitting position. In addition, the mobility of conventional office chairs is essentially limited to the height adjustment by means of a gas spring and the suspension of the backrest. Dynamic sitting is only possible to a very limited extent.

Aus diesem Grund wurden ergonomische Sitzmöbel entwickelt, mit deren Hilfe der Benutzer eine günstigere Sitzhaltung einnehmen kann. Außerdem erlauben einige dieser Sitzmöbel Bewegungen, wodurch ein Training und eine Stärkung der Rückenmuskulatur während des Sitzens erreicht sowie eine einseitige Belastung des Rückens verhindert werden kann.
So sind aus dem Stand der Technik ergonomische Sitzmöbel bekannt, die Bewegungen des Sitzteils mit einer Reihe unterschiedlicher Freiheitsgrade erlauben. Der Sitz kann dazu beispielsweise über eine Feder mit einem Standbein oder einer Standfläche verbunden sein, wobei die Feder eine vertikale federnde Bewegung oder eine seitliche Neigung des Sitzes zulässt.
Die Druckschrift EP 1 106 111 A1 zeigt einen Barhocker mit einer Rückstellvorrichtung. Zwischen einem Sitzteil und einem Fußteil sind ein Zwischenteil mit einer zentralen Säule sowie eine Federkonstruktion angeordnet. Das Zwischenteil ist an seinem unteren Ende im Fußteil kippbar und rückstellbär gehaltert. Die Rückstellvorrichtung, die den Sitz aus einer seitlichen Neigung wieder in die Grundposition zurückbringt, ist als Schwingmetall ausgebildet. Die Rückstellkraft kann durch Vorspannung mit Hilfe einer Einstellmutter eingestellt werden.
Der Benutzer des Barhockers kann dynamische Pendel- und Schwingbewegung durchführen. Durch die kontinuierliche Veränderung der Sitzhaltung wird ein ergonomisch günstiger Effekt erreicht.
Allerdings sind die gezeigten mechanischen Systeme, die ein derart flexibles dynamisches Sitzen ermöglichen, in der Regel in der Herstellung aufwendig und teuer. Ein unkompliziertes Nachrüsten vorhandener Bürostühle mit diesen Systemen ist zudem nicht praktikabel.
Es wäre ferner wünschenswert, eine schnelle und unkomplizierte optimale Einstellung der Rückstellkräfte zu ermöglichen. Insbesondere bei Bürostühlen, die von mehreren Personen abwechselnd benutzt werden sollen, ist eine rasche Verstellmöglichkeit erforderlich.
Ausgehend davon ist es die Aufgabe der vorliegenden Erfindung, ein Tragelement für einen Bürostuhl bereitzustellen, das weiche pendelnde Bewegungen des Sitzteils gegenüber dem Fußteil und somit ein dynamisches und ergonomisch günstiges Sitzen ermöglicht. Das Tragelement soll außerdem für eine Nachrüstung an bestehenden Bürostühlen geeignet sein, und eine möglichst einfache und individuelle Einstellung der Rückstellkräfte erlauben.For this reason, ergonomic seating has been developed, with the help of which the user can take a more favorable sitting posture. In addition, some of these seats allow movements, which training and strengthening the back muscles can be achieved while sitting and a one-sided load on the back can be prevented.
Thus, from the prior art ergonomic seating known that allow movements of the seat part with a number of different degrees of freedom. For this purpose, the seat can be connected, for example, via a spring with a leg or a base, wherein the spring allows a vertical resilient movement or a lateral inclination of the seat.
The publication EP 1 106 111 A1 shows a bar stool with a reset device. Between a seat part and a foot part, an intermediate part with a central pillar and a spring construction are arranged. The intermediate part is tilted at its lower end in the foot part and rückstellbär held. The restoring device, which returns the seat from a lateral inclination back to the basic position, is designed as a vibrating metal. The restoring force can be adjusted by pre-tensioning with the aid of an adjusting nut.
The user of the barstool can perform dynamic pendulum and swinging motion. By continuously changing the posture, an ergonomically favorable effect is achieved.
However, the mechanical systems shown, which allow such a flexible dynamic sitting, are usually complex to manufacture and expensive. An uncomplicated retrofitting of existing office chairs with these systems is also impractical.
It would also be desirable to allow a quick and easy optimal adjustment of the restoring forces. In particular, in office chairs that should be used by several people alternately, a quick adjustment is required.
Based on this, it is the object of the present invention to provide a support member for an office chair, which allows soft oscillating movements of the seat part relative to the foot part and thus a dynamic and ergonomically favorable sitting. The support member should also be suitable for retrofitting to existing office chairs, and allow a simple and individual adjustment of the restoring forces.

Diese Aufgabe wird gelöst durch ein Tragelement mit den Merkmalen des Anspruchs 1.
Bei dem erfindungsgemäßen Tragelement für ein Sitzmöbel, insbesondere für einen Bürostuhl, wobei das Sitzmöbel ein Sitzteil mit einem Anschlusselement und ein Fußteil aufweist, wird das Fußteil mittels eines elastischen Rückstellelements verkippbar und rückstellbar am Anschlusselement gehalten.
Insbesondere weist das Fußteil ein Anschlussteil auf, das wenigstens teilweise von dem elastischen Rückstellelement umgriffen wird, um das Fußteil am Anschlusselement zu halten. Auf diese Weise kann eine kardanische Aufhängung realisiert werden. Das elastische Rückstellelement ist bevorzugt so ausgebildet, dass das Anschlussteil des Fußteils vom elastischen Rückstellelement eingeklemmt werden kann.
Das elastische Rückstellelement ist insbesondere zwischen einem oberen Anschlagelement und dem Anschlussteil des Fußteils, und zwischen einem unteren Anschlagelement und dem Anschlussteil des Fußteils angeordnet.
Die Anschlagelemente können am Anschlussteil des Sitzteils befestigt sein. Die Verbindung kann starr sein. Allerdings kann auch wenigstens eines der Anschlagelemente höhenverstellbar am Anschlusselement befestigt sein.
Das Anschlussteil des Sitzteils wird insbesondere als ein sich nach unten erstreckendes Standrohr ausgebildet sein.
Das Anschlussteil des Fußteils steht bevorzugt mit der Außenseite des elastischen Rückstellelements in Kontakt. Jedoch ist bei einer geeigneten Ausbildung des Tragelements auch ein Umgreifen des Anschlussteils von außen her möglich.
Das elastische Rückstellelement kann wenigstens zwei sich nach außen hin erstreckende Flansche umfassen, zwischen denen das Anschlussteil des Fußteils angeordnet ist. Damit wird insbesondere ein Kontakt mit den Anschlagelementen verhindert.This object is achieved by a support element having the features of claim 1.

The connection part of the seat part will in particular be designed as a downwardly extending standpipe.
The connecting part of the foot part is preferably in contact with the outside of the elastic return element. However, with a suitable design of the support element, a gripping around of the connection part from the outside is also possible.
The elastic return element may comprise at least two outwardly extending flanges, between which the connecting part of the foot part is arranged. This prevents in particular contact with the stop elements.

Das elastische Rückstellelement umfasst wenigstens zwei separate Teile, die jeweils gewinkelt ausgebildet sind, wobei das Anschlussteil des Fußteils in den gewinkelten Ausnehmungen anliegt. Durch diese Ausbildung kann ein etwa mehr beanspruchtes Rückstellelement bei Verschleiß des Elements einfach ausgetauscht werden. Außerdem kann für ein mehr beanspruchtes Element eine robustere Gummimischung verwendet werden.The elastic return element comprises at least two separate parts, which are each formed angled, wherein the connecting part of the foot part rests in the angled recesses. With this design, an approximately more stressed restoring element can be easily replaced when the element is worn. In addition, a more durable rubber compound can be used for a more stressed element.

Das elastische Rückstellelement weist bevorzugt wenigstens einen Gummipuffer auf.The elastic return element preferably has at least one rubber buffer.

Das elastische Rückstellelement kann wenigstens aus einem Elastomer, insbesondere Polyurethan oder Naturgummi, hergestellt sein. Das Material kann auch mit einer schraubenförmigen Druckfeder vergossen werden.
Das elastische Rückstellelement weist Hohlräume im Material und/oder Ausnehmungen an den Kontaktflächen zu benachbarten Komponenten auf, um eine Veränderung der Form des elastischen Elements zu ermöglichen. Bei einer Belastung des Sitzteils kann auf diese Weise Material in die Hohlräume verdrängt werden. Die Ausnehmungen können so ausgebildet werden, dass eine gezielte Bewegung und eine Rückstellkraft für ein ergonomisch günstiges Sitzen ermöglicht wird.
Das Tragelement weist insbesondere Mittel zum Einstellen und zur Veränderung der Rückstellkraft des elastischen Rückstellelements auf.
Das Tragelement umfasst bevorzugt eine Betätigungseinrichtung zum Einstellen und zur Veränderung der Rückstellkraft des elastischen Rückstellelements. Insbesondere kann die Rückstellkraft des elastischen Rückstellelements kontinuierlich eingestellt bzw. verändert werden. Außerdem kann die Rückstellkraft des elastischen Rückstellelements stufenweise eingestellt bzw. verändert werden.
Die Mittel sind insbesondere zur Veränderung des Abstands zwischen einem oberen Anschlagelement und einem unteren Anschlagelement ausgebildet. Der Abstand der Anschlagelemente ist veränderbar, um das elastische Element einstellbar zu deformieren. Die Veränderung des Abstands der Anschlagelemente kann beispielsweise durch eine am unteren Ende des starren Elements angeordnete Flügelmutter einstellbar sein. Der Abstand der Anschlagelemente kann auch durch einen zwischen einen
Flansch und einem Anschlagelement angeordneten Nocken einstellbar sein.The elastic return element can be made of at least one elastomer, in particular polyurethane or natural rubber. The material can also be cast with a helical compression spring.
The elastic return element has cavities in the material and / or recesses at the contact surfaces to adjacent components to allow a change in the shape of the elastic member. With a load of the seat part can be displaced in this way, material in the cavities. The recesses can be formed so that a targeted movement and a restoring force for ergonomically favorable sitting is possible.
The support element has in particular means for adjusting and for changing the restoring force of the elastic return element.
The support element preferably comprises an actuating device for setting and changing the restoring force of the elastic return element. In particular, the restoring force of the elastic return element can be adjusted or changed continuously. In addition, the restoring force of the elastic return element can be adjusted or changed in stages.
The means are designed in particular for changing the distance between an upper stop element and a lower stop element. The distance between the stop elements is variable to adjustably deform the elastic element. The change in the spacing of the stop elements can be adjustable, for example, by a wing nut arranged at the lower end of the rigid element. The distance between the stop elements can also be separated by a
Flange and a stop element arranged cam be adjustable.

Die Mittel können alternativ zur Veränderung des Abstands zwischen dem Anschlussteil des Fußteils und dem Anschlusselements des Sitzteils ausgebildet sein. So kann an einem Rohrstück wenigstens ein konisches Element verschiebbar angeordnet sein, um die Rückstellkraft des elastischen Rückstellelements einzustellen bzw. zu verändern. Auch kann der Radius des starren Elements veränderbar sein, um die Rückstellkraft des elastischen Rückstellelements einzustellen bzw. zu verändern.
Die Mittel können auch zum Zusammenpressen des elastischen Rückstellelements von außen her ausgebildet sein.
Die Aufgabe wird auch gelöst durch ein Sitzmöbel, insbesondere einen Bürostuhl, mit einem Sitzteil und einem Fußteil, wobei das Sitzteil ein Tragelement wie vorher beschrieben aufweist.The means may alternatively be designed to change the distance between the connection part of the foot part and the connection element of the seat part. Thus, at least one conical element can be displaceably arranged on a pipe section in order to set or change the restoring force of the elastic return element. Also, the radius of the rigid member may be variable to adjust the restoring force of the elastic return element or change.
The means may also be designed for compressing the elastic return element from the outside.
The object is also achieved by a chair, in particular an office chair, with a seat part and a foot part, wherein the seat part has a support element as previously described.

Das Sitzmöbel umfasst insbesondere eine höhenverstellbare Gasfeder, die mit dem Sitzteil verbunden ist.

Die Ausführungsformen gemäß den Figuren 6 bis 8 sind nicht Teil der Erfindung.The embodiments according to the FIGS. 6 to 8 are not part of the invention.

In Figur 1 ist ein Tragelement 1 für eine hier nicht weiter dargestellte Sitzvorrichtung mit einem Standbein, wie dies von herkömmlichen Bürostühlen bekannt ist, in einer vertikalen Schnittansicht gezeigt.
Das Tragelement 1 weist ein als Fünfsternfuß ausgebildetes Fußteil auf. Das Fußteil ist über ein Anschlusselement 2 und ein elastisches Element 19, 24 mit einer sich zentral nach unten erstreckenden Rohrstück 8 verbunden. Das Tragelement 1 für das Sitzteil umfasst ein Standrohr 3 und eine höhenverstellbaren Gasfeder 4. Drehbewegungen des Sitzteils gegenüber dem Fußteil 2 können durch den Einsatz eines entsprechenden Lagers ermöglicht werden.
Die Gasfeder 4 weist in üblicher Weise eine Befestigungsstange 5 auf, deren freies Ende 6 in einem federelastischen Element 7, hier einem Gummizylinder 7, eingebettet ist. Der Gummizylinder 7 ist in ein Rohrstück 8 eingepresst, das an seinem unteren Endbereich einen eingeschweißten Böden 9 aufweist. Durch Betätigung eines Betätigungselements, beispielsweise eines Hebels, kann die Sitzhöhe variabel eingestellt werden.In FIG. 1 is a support member 1 for a not shown seat device with a leg, as is known from conventional office chairs, shown in a vertical sectional view.
The support element 1 has a trained as a five-star base foot. The foot part is connected via a connecting element 2 and an elastic element 19, 24 with a centrally downwardly extending piece of pipe 8. The support member 1 for the seat part comprises a standpipe 3 and a height-adjustable gas spring 4. Rotary movements of the seat part relative to the foot part 2 can be made possible by the use of a corresponding bearing.
The gas spring 4 has a mounting rod 5 in the usual manner, the free end 6 in a resilient element 7, here a rubber cylinder 7, is embedded. The blanket cylinder 7 is pressed into a tube piece 8, which has a welded-in bottoms 9 at its lower end region. By operating an actuating element, such as a lever, the seat height can be variably adjusted.

Das Ende der Befestigungsstange 5 drückt bei einer Belastung von oben auf den Gummizylinder 7 und staucht diesen zusammen. Auf diese Weise entsteht die Wirkung einer Tiefenfederung, deren Härte von der Auswahl der Härte des Gummis abhängt. Am oberen Ende des Rohrstücks 8 ist eine Ringscheibe 11 angeschweißt, durch deren kreisrunde Öffnung 12 die Befestigungsstange 5 hindurchgeführt ist. Auf die Ringscheibe 11 ist ein konusförmiges Rohrstück 12 angeschweißt, in welchem das Standrohr 3 eingepresst ist.
Am unteren Endbereich 14 des Rohrstückes 8 ist ein Außengewinde 15 vorgesehen, auf welches eine Flügelmutter 16 aufgeschraubt ist. Eine zweite Ringscheibe 17 ist auf das Rohrstück 8 geschoben und liegt an der Oberseite der Flügelmutter 16 auf. Zwischen der ersten Ringscheibe 11 bzw. dem Rohrstück 8 und dem Fußteil 2 ist ein flanschförmiger Gummipuffer 19 vorgesehen, der oben eine konisch zulaufende Ringnut 20 und im Kniebereich 21 eine äußere Ringnut 22 aufweist. Ein identischer Gummipuffer 24 ist zwischen der zweiten Ringscheibe 17 bzw. dem Rohrstück 8 und dem unteren Bereich des Fußteils 2 eingeklemmt. Zwischen dem Gummipuffer 24 und dem Fußteil 2 ist zusätzlich eine Gleitscheibe 25 vorgesehen, um die Druckauflage der schmalen Unterseite des Fußteils 2 auf eine größere Fläche zu verteilen. Mittels der Flügelmutter 16 kann der horizontale Federweg der Federung eingestellt werden. Auf diese Weise kann die Einstellung der Rückstellkräfte bei Pendelbewegungen des Sitzteils individuell gewählt werden.
Jeder der Gummipuffer 19, 24 ist im wesentlichen ringförmig ausgebildet, um das Rohrstück 8 zu umgreifen. Es können jedoch auch Unterbrechungen vorgesehen sein. Die sich nach außen erstreckenden Flansche greifen zwischen die obere Ringscheibe 11 und das Anschlussteil 2 des Fußteils bzw. zwischen die Gleitscheibe 25 und die untere Ringscheibe 17 ein. Das Anschlussteil 2 des Fußteils ist auf diese Weise zwischen den Flanschen eingeklemmt. Dadurch ist eine einfache kardanische Aufhängung realisiert, um eine Bewegung des Sitzteils gegenüber dem Fußteil mit mehreren Freiheitsgraden zu ermöglichen. Außerdem ist der Aufbau einfach. Die Gummipuffer 19, 24 sind leicht auswechselbar oder nachrüstbar.
Die Gummipuffer 19 und 24 dienen somit als Aufhängung für das am Rohrstück 8 befestigte Standrohr 3. Somit können mit dem Sitz des Bürostuhls Kreis- und Pendelbewegungen durchgeführt werden, was zu einer erheblichen Entlastung und Stärkung des Rückens führt.The end of the mounting rod 5 presses on a load from above on the blanket cylinder 7 and compresses it together. In this way, the effect of a deep suspension, the hardness depends on the choice of the hardness of the rubber. At the upper end of the pipe section 8, an annular disc 11 is welded, through the circular opening 12, the mounting rod 5 is passed. On the annular disc 11, a cone-shaped pipe section 12 is welded, in which the standpipe 3 is pressed.
At the lower end portion 14 of the pipe section 8, an external thread 15 is provided, on which a wing nut 16 is screwed. A second annular disc 17 is pushed onto the pipe section 8 and is located on top of the wing nut 16. Between the first annular disc 11 and the tube piece 8 and the foot part 2, a flange-shaped rubber buffer 19 is provided which has a tapered annular groove 20 at the top and an outer annular groove 22 in the knee region 21. An identical rubber buffer 24 is clamped between the second annular disc 17 and the tubular piece 8 and the lower portion of the foot part 2. Between the rubber buffer 24 and the foot part 2, a sliding washer 25 is additionally provided to distribute the pressure pad of the narrow underside of the foot part 2 over a larger area. By means of the wing nut 16, the horizontal travel of the suspension can be adjusted. In this way, the setting of the restoring forces can be selected individually for pendulum movements of the seat part.
Each of the rubber bumpers 19, 24 is formed substantially annular to engage around the pipe section 8. However, it can also be provided interruptions. The outwardly extending flanges engage between the upper ring disk 11 and the connecting part 2 of the foot part or between the sliding disk 25 and the lower annular disk 17. The connection part 2 of the foot part is clamped in this way between the flanges. As a result, a simple gimbal is realized to allow movement of the seat part relative to the foot part with multiple degrees of freedom. In addition, the structure is simple. The rubber buffers 19, 24 are easily replaceable or retrofitted.
The rubber buffers 19 and 24 thus serve as a suspension for the pipe section 8 fixed standpipe 3. Thus, can be performed with the seat of the office chair circular and pendulum movements, resulting in a considerable relief and strengthening the back.

Zwischen dem Sitzteil und dem Fußteil besteht lediglich über die Gummipuffer 19, 24 Kontakt. Das Tragelement 1 federt sowohl vertikale als auch pendelnde Bewegungen des Benutzers ab.
Das beschriebene Tragelement 1 ist im Aufbau einfach. So sind die Gummipuffer bei Bedarf austauschbar. Außerdem sind vorhandene Bürostühle einfach nachrüstbar. In einer vereinfachten Ausführung kann auf die Flügelmutter 16 verzichtet werden, wobei dann die zweite Ringscheibe 17 ebenfalls am Rohrstück 8 befestigt ist.
Die Gummipuffer 19 und 24 und der Gummizylinder 7 bestehen aus einem geeigneten Elastomer, beispielsweise aus Polyurethan (PU) oder Naturkautschuk. Bei der Verwendung von Naturkautschuk wird dieser vorzugsweise mit der Befestigungsstange 5 direkt im Rohrstück 8 vulkanisiert. Das Polyurethan oder der Naturgummi können auch zusammen mit einer schraubenförmigen Druckfeder vergossen werden.
Durch das Zusammenspiel der Tiefenfederung mit der regulierbaren Pendelbewegung wird eine Bewegung mit einer Vielzahl von Freiheitsgraden ermöglicht. Es versteht sich für den Fachmann, dass das Tragelement 1 besonders kostengünstig produziert werden kann, so dass ein Umrüsten von bestehenden Stühlen, wie Bürostühlen und dergleichen, besonders attraktiv wird. Das Tragelement 1 kann selbstverständlich auch für neue Bürostühle verwendet werden, wobei in diesem Fall das Standrohr 3 direkt an die erste Ringscheibe 1 angeschweißt sein kann. Das konusförmige Rohrstück 12 kann dann entfallen.
In Figur 2 ist eine weitere Ausführungsform des Tragelements 1 mit einer Verbindungsvorrichtung dargestellt, bei der die Einstellung der Rückstellkräfte bei Pendelbewegungen durch Veränderung des Abstands zwischen einem starr mit dem Rohrstück 8 verbundenen Auflageflansch 26 und einer höhenverstellbaren oberen Ringscheibe 27 erfolgt. Die Höheneinsteliung der Ringscheibe 27 am Rohrstück 8 wird mit Hilfe einer Stelleinrichtung bewerkstelligt, von der jedoch in der Figur 2 zur Vereinfachung nur schematisch ein Nocken 28 dargestellt ist. Der Nocken 28 ist beispielsweise zwischen der höhenverstellbaren Ringscheibe 27 und dem Abschlussflansch 30 angeordnet.
In der in der Figur angedeuteten Stellung des Nockens 28 befindet sich die obere Ringscheibe 27 in ihrer maximalen Höhe am Rohrstück 8 Dies bedeutet, dass die Gummipuffer 19 und 24 maximal entlastet sind. In dieser Einstellung ist eine relativ weiche seitliche Pendelbewegung des Sitzteils gegenüber dem Fußteil möglich.
Durch Drehen des Nockens 28 mittels einer geeigneten Betätigungsvorrichtung kann die Ringscheibe 27 weiter nach unten verschoben werden, wodurch die Gummipuffer 19 und 24 züsammengepresst werden. Auf diese Weise wird die Rückstellvorrichtung härter eingestellt. Eine Pendelbewegung erfordert dann vom Benutzer dann einen höheren Kraftaufwand. Das Gummilager wird in der Richtung der senkrechten Achse des Rohrstücks 8 zusammengepresst, um die Härte des Gummilagers für die seitliche Pendelbewegung einzustellen.
Die Darstellung der Höhenverstelleinrichtung durch den Nocken 28 in der Figur 2 ist stark vereinfacht. So können beispielsweise mehrere Nocken an verschiedenen Stellen zwischen der Ringscheibe 27 und dem Abschlussflansch 30 vorgesehen sein. Außerdem wird in der Regel der Nocken 28 durch Drehen eines Handrades mit einer bestimmten Übersetzung eingestellt werden können, um eine genaue und stufenlose Verformung der Gummipuffer 19 und 24 und der Rückstellkräfte zu ermöglichen. Alternativ ist eine abgestufte Einstellung der Höhenlage der Ringscheibe 27, beispielsweise durch einen zackig ausgebildeten Nocken oder mittels eines Hebels mit Rasterarretierung denkbar.Between the seat part and the foot part is only on the rubber buffers 19, 24 contact. The support element 1 absorbs both vertical and oscillating movements of the user.
The support element 1 described is simple in construction. So the rubber buffers are interchangeable if necessary. In addition, existing office chairs are easy to retrofit. In a simplified embodiment can be dispensed with the wing nut 16, in which case the second annular disc 17 is also attached to the pipe section 8.
The rubber pads 19 and 24 and the blanket cylinder 7 are made of a suitable elastomer, such as polyurethane (PU) or natural rubber. When natural rubber is used, it is preferably vulcanized directly with the fastening rod 5 in the pipe section 8. The polyurethane or natural rubber can also be cast together with a helical compression spring.
The interaction of the depth suspension with the adjustable pendulum movement enables a movement with a large number of degrees of freedom. It is understood by those skilled in the art that the support element 1 can be produced particularly cost-effectively, so that a conversion of existing chairs, such as office chairs and the like, is particularly attractive. The support element 1 can of course also be used for new office chairs, in which case the standpipe 3 can be welded directly to the first annular disc 1. The cone-shaped pipe section 12 can then be omitted.
In FIG. 2 a further embodiment of the support member 1 is shown with a connecting device in which the adjustment of the restoring forces during oscillations by changing the distance between a rigidly connected to the pipe section 8 support flange 26 and a height-adjustable upper annular disc 27 takes place. The Höheneinsteliung the annular disc 27 on the pipe section 8 is accomplished by means of an adjusting device, of which, however, in the FIG. 2 For simplicity, only a cam 28 is shown schematically. The cam 28 is arranged, for example, between the height-adjustable annular disc 27 and the end flange 30.
In the direction indicated in the figure position of the cam 28, the upper annular disc 27 is at its maximum height on the pipe section 8 This means that the rubber buffers 19 and 24 are maximally relieved. In this setting, a relatively soft lateral pendulum movement of the seat part relative to the foot part is possible.
By turning the cam 28 by means of a suitable actuating device, the annular disc 27 can be moved further downwards, whereby the rubber buffers 19 and 24 are pressed together. In this way, the return device is set harder. A pendulum motion then requires the user then a higher effort. The rubber bearing is compressed in the direction of the vertical axis of the pipe section 8 to adjust the hardness of the rubber bearing for the lateral pendulum movement.
The representation of the height adjustment by the cam 28 in the FIG. 2 is greatly simplified. For example, several cams may be provided at different locations between the annular disc 27 and the end flange 30. In addition, as a rule, the cam 28 can be adjusted by turning a handwheel with a certain gear ratio to allow accurate and continuous deformation of the rubber buffers 19 and 24 and the restoring forces. Alternatively, a graduated adjustment of the altitude of the annular disc 27, for example by a jagged cam or by means of a lever with ratchet locking conceivable.

Figur 3 zeigt einen Teil eines Tragelements 1 mit einer Einstellmöglichkeit für die Rückstellkraft, wobei der Übersicht halber die Gummipuffer und das Anschlussteil des Fußteils 2 nicht dargestellt sind. In dieser Ausführungsform wird die Härte des Gummilagers durch die Anordnung eines höhenverstellbaren Konus 31 am Rohrstück 8 eingestellt. Zusätzlich kann ein weiterer Konus 32 feststehend oder ebenfalls höhenverstellbar am Rohrstück 8 angeordnet sein. Der untere Konus 32 kann eine eigenständige Bewegung und/oder eine Relativbewegung zum oberen Konus 31 ausführen. Je nach der Höhenlage des Konus/der Koni am Rohrstück 8 werden die (nicht dargestellten) Gummipuffer deformiert, wodurch sich die elastischen Eigenschaften der Rückstellvorrichtung hinsichtlich der seitlichen Auslenkung des Gummilagers verändern. Zur Einstellung und Verstellung der Lage des Konus 31, 32 bzw. der Koni 31, 32 sind dem Fachmann verschiedene Möglichkeiten bekannt, die an dieser Stelle nicht im einzelnen angeführt werden sollen. Als Betätigungselement kann beispielsweise ein Handrad oder ein Hebel mit Rasterarretierung dienen. So ist eine Einstellung der Rückstellkräfte bequem und schnell durchführbar.
In Figur 4 ist eine weitere Ausführungsform des Tragelements 1 mit der Verbindungsvorrichtung dargestellt. In dieser Ausführungsform sind beide Anschlagflansche 26 und 27 in einem vorgegebenen Abstand voneinander fixiert. Eine Deformation der Gummipuffer 19 und 24 wird hier mittels einer radialen Krafteinwirkung auf die Gummipuffer 19 und 24 bewerkstelligt. Der radiale Abstand eines Wandstücks 33 kann entsprechend einer gewünschten Einstellung der Härte des Gummilagers variabel eingestellt werden. Das Wandstück 33 kann beispielsweise in Form zweier Halbzylinder ausgebildet sein, deren Abstand zueinander veränderbar ist.
In Figur 5a ist eine weitere Möglichkeit zur Einstellung der Rückstellkraft des Gummilagers gezeigt. Die Verbindungsvorrichtung weist Schlauchklemmen 34 und 35 auf, die zwischen dem oberen Anschlagflansch 26 und dem Anschlußteil 2 des Fußteils und/ oder dem unteren Anschlagflansch 27 und dem Anschlußteil 2 des Fußteils bzw. der Gleitscheibe 25 angeordnet sind.
Es wäre auch denkbar, das Anschlussteil 2 des Fußteils so auszubilden, dass sein innerer Radius verstellbar ist, um den Abstand zum Rohrstück 8 zu verstellen. Auf diese Weise könnte das elastische Element von außen her mehr oder weniger zusammengedrückt und so die Rückstellkraft eingestellt werden. FIG. 3 shows a part of a support member 1 with an adjustment for the restoring force, the sake of clarity, the rubber buffers and the connection part of the foot part 2 are not shown. In this embodiment, the hardness of the rubber bearing is adjusted by the arrangement of a height-adjustable cone 31 on the pipe section 8. In addition, a further cone 32 fixed or also adjustable in height can be arranged on the pipe section 8. The lower cone 32 can perform an independent movement and / or a relative movement to the upper cone 31. Depending on the altitude of the cone / Koni the pipe section 8 (not shown) rubber buffer are deformed, thereby changing the elastic properties of the return device with respect to the lateral deflection of the rubber bearing. For adjustment and adjustment of the position of the cone 31, 32 and the Koni 31, 32 the skilled person various possibilities are known, which should not be mentioned in detail at this point. As an actuating element, for example, a handwheel or a lever with ratchet locking serve. Thus, an adjustment of the restoring forces is convenient and quick to carry out.
In FIG. 4 a further embodiment of the support member 1 is shown with the connecting device. In this embodiment, both stop flanges 26 and 27 are fixed at a predetermined distance from each other. A deformation of the rubber pads 19 and 24 is accomplished here by means of a radial force on the rubber buffers 19 and 24. The radial distance of a wall piece 33 can accordingly a desired adjustment of the hardness of the rubber bearing can be variably adjusted. The wall piece 33 may be formed, for example, in the form of two half-cylinders whose distance from each other is variable.
In FIG. 5a is another way to adjust the restoring force of the rubber bearing shown. The connecting device has hose clamps 34 and 35 which are arranged between the upper stop flange 26 and the connecting part 2 of the foot part and / or the lower stop flange 27 and the connecting part 2 of the foot part or the sliding disk 25.
It would also be conceivable to design the connection part 2 of the foot part such that its inner radius is adjustable in order to adjust the distance to the pipe section 8. In this way, the elastic element could be more or less compressed from the outside and so the restoring force can be adjusted.

Eine der in der Ausführungsform gemäß Figur 5a verwendeten Schlauchklemmen 34 im Schnitt A-A ist in Figur 5b dargestellt. Durch Drehen eines Einstellrads 36 kann der Umfang des Pressrings 37 der Schlauchklemme 34 verändert werden. Bei einer Verkleinerung des Umfangs werden die Gummipuffer 19 und/oder 24 nach innen zusammengequetscht, wodurch sich die Härte des Gummilagers insgesamt einstellen lässt. Um nach wie vor eine Pendelbewegung zu ermöglichen, müssen die Schlauchklemmen 34, 35 in vertikaler Richtung relativ flexibel ausgebildet sein. Alternativ könnten die Schlauchklemmen 34, 35 auch flach ausgebildet und beispielsweise in eine Nut 38 in den Gummipuffern 19 bzw. 24 eingepasst sein, wie in Figur 5c verdeutlicht. Da in diesem Fall genügend Bewegungsspielraum zwischen dem Anschlussteil 2 des Fußteils und dem feststehenden Flansch 26 zur Durchführung der Pendelbewegung vorhanden ist, kann die flach ausgebildete Schlauchklemme 34 hier aus einem relativ starren Material bestehen.
Es ist außerdem denkbar, eine Schlauchklemme am Außenbereich des bügelartigen Anschlussteils 2 des Fußteils anzuordnen, sofern der oder die Bügel so ausgebildet sind, dass eine radiale Verschiebung möglich ist.
Insgesamt können die Merkmale, die in Bezug auf die einzelnen Ausführungsbeispiele beschrieben wurden, kombiniert werden, um eine möglichst einfache und genaue Einstellung der Rückstellkräfte zu ermöglichen.One of the embodiments according to FIG. 5a used hose clamps 34 in section AA is in FIG. 5b shown. By turning a dial 36, the circumference of the press ring 37 of the hose clamp 34 can be changed. With a reduction in the circumference, the rubber bumpers 19 and / or 24 are squeezed inwardly, whereby the hardness of the rubber bearing can be adjusted in total. In order to still allow a pendulum motion, the hose clamps 34, 35 must be relatively flexible in the vertical direction. Alternatively, the hose clamps 34, 35 could also be formed flat and, for example, fitted in a groove 38 in the rubber buffers 19, 24, as in FIG FIG. 5c clarified. Since in this case there is sufficient freedom of movement between the connecting part 2 of the foot part and the fixed flange 26 for carrying out the oscillating movement, the flat-shaped hose clamp 34 can here consist of a relatively rigid material.
It is also conceivable to arrange a hose clamp on the outer region of the bow-shaped connecting part 2 of the foot part, provided that the one or more brackets are formed so that a radial displacement is possible.
Overall, the features that have been described with respect to the individual embodiments, combined to allow the simplest possible and accurate adjustment of the restoring forces.

In Figur 6 ist ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Tragelements 1 ebenfalls in der Seitenansicht dargestellt. Der obere Bereich mit der Stahdrohrkonstruktion bis zu der ersten Ringscheibe 11 ist identisch.In FIG. 6 is a further embodiment of a support element 1 according to the invention also shown in the side view. The upper area with the Stahdrohrkonstruktion up to the first annular disc 11 is identical.

Am unteren Endbereich 14 des Rohrstückes 8 ist auch hier ein Außengewinde 15 vorgesehen, auf welches eine Flügelmutter 16 aufgeschraubt ist. Ebenfalls ist eine zweite Ringscheibe 17 auf das Rohrstück 8 geschoben und liegt an der Oberseite der Flügelmutter 16 auf.
Zwischen der ersten Ringscheibe 11 bzw. dem Rohrstück 8 und dem Fußteil 2 ist ein flanschförmiger, einteiliger Gummipuffer 19' vorgesehen, der oben und unten eine konisch zulaufende Ringnut 20 und im Kniebereich 21 eine äußere Ringnut 22 aufweist. Zwischen dem Gummipuffer 19' und dem Fußteil 2 ist wie zuvor eine Gleitscheibe 25 vorgesehen, um die Druckauflage der schmalen Unterseite des Fußteils 2 auf eine größere Fläche zu verteilen. Vorzugsweise ist der Gummipuffer 19' symmetrisch ausgebildet und ist somit auf der unteren Seite im Bereich der Gleitscheibe 25 und der Ringscheibe 17 in seiner Formgebung identisch zur oberen Seite. Mittels der Flügelmutter 16 kann auch hier der horizontale Federweg der Federung eingestellt werden. Auf diese Weise kann die Einstellung der Rückstellkräfte bei Pendelbewegungen des Sitzteils individuell gewählt werden.
Der Gummipuffer 19' ist im Wesentlichen auch hier ringförmig ausgebildet, um das Rohrstück 8 zu umgreifen. Die sich nach außen erstreckenden Flansche greifen zwischen die obere Ringscheibe 11 und das Anschlussteil 2 des Fußteils bzw. zwischen die Gleitscheibe 25 und die untere Ringscheibe 17 ein. Das Anschlussteil 2 des Fußteils ist auf diese Weise zwischen den Flanschen eingeklemmt. Die Auswirkungen und Funtkionen dieses Gummipuffers 19' entsprechen im Wesentlichen der der Gummipuffer 19, 24 aus Figur 1. Der Gummipuffer 19' ist leicht auswechselbar oder nachrüstbar. Zwischen dem Sitzteil und dem Fußteil besteht lediglich über den Gummipuffer 19' Kontakt. Das Tragelement 1 federt ebenfalls sowohl vertikale als auch pendelnde Bewegungen des Benutzers ab. Der Hülsenteil 19" kann aus Gründen der einfachen Montage Längsschlitze geeigneter Länge und Breite aufweisen.At the lower end portion 14 of the pipe section 8, an external thread 15 is also provided here, on which a wing nut 16 is screwed. Also, a second annular disc 17 is pushed onto the pipe section 8 and is located on the top of the wing nut 16.
Between the first annular disc 11 and the tubular piece 8 and the foot part 2, a flange-shaped, one-piece rubber buffer 19 'is provided which has a tapered annular groove 20 at the top and bottom and an external annular groove 22 in the knee region 21. As before, a sliding disk 25 is provided between the rubber buffer 19 'and the foot part 2 in order to distribute the pressure support of the narrow underside of the foot part 2 over a larger area. Preferably, the rubber buffer 19 'is formed symmetrically and is thus on the lower side in the region of the sliding disk 25 and the annular disc 17 in its shape identical to the upper side. By means of the wing nut 16, the horizontal travel of the suspension can also be adjusted here. In this way, the setting of the restoring forces can be selected individually for pendulum movements of the seat part.
The rubber buffer 19 'is also substantially annular here in order to encompass the pipe section 8. The outwardly extending flanges engage between the upper ring disk 11 and the connecting part 2 of the foot part or between the sliding disk 25 and the lower annular disk 17. The connection part 2 of the foot part is clamped in this way between the flanges. The effects and functions of this rubber buffer 19 'essentially correspond to those of the rubber bumpers 19, 24 FIG. 1 , The rubber buffer 19 'is easily replaceable or retrofitted. There is only contact via the rubber buffer 19 'between the seat part and the foot part. The support element 1 also absorbs both vertical and oscillating movements of the user. The sleeve member 19 "may have longitudinal slots of suitable length and width for ease of assembly.
