In der US 2,541,955 A ist ein fahrbarer Schaukelstuhl mit Kippbegrenzung beschrieben.In the US 2,541,955 A is a mobile rocking chair with tilt limitation described.

Stühle des täglichen Gerbauchs weisen üblicherweise vier Stuhlbeine auf, die an einem Ende mit einer Sitzfläche verbunden sind, auf welcher sich ein Nutzer setzen kann. Mit ihrer von der Sitzfläche abgewandten Seite kontaktieren die Stuhlbeine in der Regel den Boden, auf dem der Stuhl abgestellt wird. Hiervon zu unterscheiden sind Schaukelstühle mit bogenförmigen Abstellfüßen, Bürostühle oder dergleichen.Chairs of the Everyday Gerbauch usually have four chair legs, which are connected at one end with a seat on which a user can sit down. With their side facing away from the seat, the chair legs usually contact the floor on which the chair is placed. To distinguish this are rocking chairs with arcuate Abstellfüßen, office chairs or the like.

Aus der Schweizer Patentschrift der CH 196124 ist eine Vorrichtung zur Kippbegrenzung von Flachschleifwippen bekannt. Die DE 3603884 betrifft einen Kippstuhl mit einem um etwa 90 Grad schwenkbaren Kipptisch.From the Swiss patent specification of CH 196124 is a device for tilt limitation of flat rockers known. The DE 3603884 relates to a tilting chair with a tiltable about 90 degrees tilting table.

Die vorliegende Erfindung beruht auf der Erkenntnis, dass viele Nutzer eines Stuhls von Zeit zu Zeit auf dem Stuhl wippen oder kippeln, um einem natürlichen Bewegungsdrang nachzugeben. Dies gilt vor allem für Kinder. Beim Wippen mit dem eingangs genannten Stuhl wird der Stuhl von einer Ausgangsstellung, in welcher alle vier Stuhlbeine den Boden unmittelbar berühren, in eine Wippstellung überführt, in der nur noch zwei der vier Stuhlbeine bis zum Boden reichen, während die beiden anderen frei schwebend mit Abstand zum Boden gehalten sind. Hierbei lassen sich Stürze mit Verletzungen im Gefolge nicht immer sicher vermeiden.The present invention is based on the recognition that many users of a chair from time to time bobbing or tilting on the chair to give in to a natural urge to move. This is especially true for children. When rocking with the above-mentioned chair, the chair is transferred from a starting position in which all four chair legs touch the ground directly, in a rocking position, in which only two of the four chair legs reach to the ground, while the other two free-floating with distance are held to the ground. In this case, falls with injuries in the wake can not always be safely avoided.

In dem Domicil Kompetenzzentrum Demenz Bethlehemacker wurde festgestellt, dass ein solches Wippen auch vielen Erwachsenen Spaß macht. Dies gilt insbesondere für erwachsene Personen mit Gehirnerkrankungen, wie beispielsweise Menschen mit einer mittleren bis schweren Demenz. Ein Sturz kann jedoch gerade bei Erwachsenen schlimme Folgen haben.In the Domicil Center of Excellence Dementia Bethlehemacker it was found that such a seesaw is also fun for many adults. This is especially true for adults with brain disorders, such as people with moderate to severe dementia. A fall, however, can have dire consequences, especially in adults.

Aufgabe der Erfindung ist es eine Kippbegrenzungseinrichtung und einen Stuhl der eingangs genannten Art bereitzustellen, mit denen Stürze beim Wippen sicher vermieden werden können.The object of the invention is to provide a Kippbegrenzungseinrichtung and a chair of the type mentioned, with which falls during rockers can be safely avoided.

Die Erfindung löst diese Aufgabe ausgehend von der eingangs genannten Kippbegrenzungseinrichtung dadurch, dass eine Ausschwenkbegrenzung eine sich in eine Längsrichtung erstreckende Ausschwenkbegrenzungsstange umfasst, die mit ihrem Anlenkende drehbar an einem Befestigungselement befestigt ist und ein Langloch aufweist, wobei sich ein fest mit einem zugeordneten Abstützbein verbundener Anschlagbolzen durch das Langloch hindurch erstreckt.The invention solves this problem, starting from the above-mentioned Kippbegrenzungseinrichtung in that a Ausschwenkbegrenzung a extending in a longitudinal direction Ausschwenkbegrenzungsstange includes, which is rotatably attached with its articulation end to a fastener and having a slot, with a fixedly connected to an associated Abstützbein stop pin extends through the slot.

Ausgehend von dem eingangs genannten Stuhl löst die Erfindung die Aufgabe dadurch, dass der Stuhl über eine solche Kippbegrenzungseinrichtung verfügt.Based on the above-mentioned chair, the invention solves the problem in that the chair has such Kippbegrenzungseinrichtung.

Erfindungsgemäß ist eine Kippbegrenzungseinrichtung geschaffen, die mit ihren Befestigungselementen an dem Stuhl, insbesondere jeweils an einem Stuhlbein befestigt werden kann. Die Befestigungselemente weisen ein Schwenk- oder Drehlager auf, in dem ein Schwenkträger schwenkbar gelagert ist. Mit anderen Worten halten die Befestigungselemente den sich zwischen ihnen erstreckenden Schwenkträger drehbar an den beiden hinteren Stuhlbeinen. Der Schwenkträger ist weiterhin drehfest mit einem Abstützbein verbunden, das beim Wippen mit dem Stuhl ausschwenkt. Unter dem Begriff Ausschwenken ist hier gemeint, dass in einer Seitenansicht sich der zwischen dem Abstützbein und dem Befestigungselement bezüglich des Schwenkträgers aufgespannte Winkel vergrößert. Genauer formuliert vergrößert sich ein Schwenkwinkel, der von dem gedachten Lot des Drehlagers, also einer virtuellen senkrecht zum Boden verlaufenden Achse, und der Längsachse des Abstützbeins bezüglich des Drehlagers aufgespannt wird. Durch die drehfeste Verbindung zwischen Schwenkträger und Abstützbein wird eine Drehung des Schenkträgers zwangsläufig in eine Drehbewegung des oder der Abstützbeine überführt.According to the invention, a tilt-limiting device is provided which can be fastened with its fastening elements to the chair, in particular to a chair leg in each case. The fasteners have a pivot or pivot bearing in which a pivot support is pivotally mounted. In other words, the fasteners rotatably hold the pivot support extending therebetween on the two rear chair legs. The swivel carrier is further rotatably connected to a support leg, which swings when rocking with the chair. The term swiveling here means that in a side view, the angle spanned between the support leg and the fastening element with respect to the pivot support increases. Specifically formulated enlarges a pivot angle, which is spanned by the imaginary Lot of the pivot bearing, ie a virtual perpendicular to the ground axis, and the longitudinal axis of Abstützbeins respect to the pivot bearing. Due to the non-rotatable connection between the pivot carrier and Abstützbein a rotation of the gift carrier is inevitably transferred into a rotational movement of the or the support legs.

Darüber hinaus sind im Rahmen der Erfindung Schwenkbegrenzungsmittel vorgesehen, die zur Begrenzung der Schwenkbewegung des Schwenkträgers in wenigstens einer Richtung eingerichtet sind. Die Begrenzung der Schwenkbewegung erfolgt beispielsweise durch die Begrenzung der maximalen Ausschwenkbewegung des Abstützbeins. Auf diese Weise ist auch der Winkel, den das Stuhlbein in einer Seitenansicht beim Wippen mit dem Boden aufspannt, begrenzt und somit ein Sturz, also ein Umkippen des Stuhls nach hinten, verhindert. Im Rahmen der Erfindung können die Nutzer somit Wippen, ohne das die Gefahr eines Sturzes besteht. Hierdurch wird das Aufsichtspersonal, also Eltern oder Krankenpfleger, deutlich entlastet, wobei die Nutzer ihrem Bewegungsdrang freien Lauf lassen können.In addition, in the context of the invention pivot limiting means are provided, which are set up to limit the pivoting movement of the pivot carrier in at least one direction. The limitation of the pivoting movement, for example, by limiting the maximum Ausschwenkbewegung the Abstützbeins. This is also true the angle that the chair leg spans in a side view when rocking with the ground, limited and thus a fall, so the chair tipped backwards prevented. In the context of the invention, the users can thus rockers, without the risk of falling. As a result, the supervisory staff, so parents or nurses, significantly relieved, the user can let their urge for exercise free rein.

Im Rahmen der Erfindung weist die Ausschwenkbegrenzung eine sich in einer Längsrichtung erstreckende Ausschwenkbegrenzungstange auf, die mit ihrem Anlenkende drehbar an einem Befestigungselement befestigt ist und ein Langloch aufweist, wobei sich ein fest mit einem zugeordneten Abstützbein verbundener Anschlagbolzen durch das Langloch hindurch erstreckt. Das Langloch ist so dimensioniert, dass das Abstützbein sich mit seinem Anschlagbolzen frei in dem Langloch bewegen kann bis der Anschlagbolzen an dem hinteren Ende des Langlochs anschlägt und ein weiteres Ausschwenken des Abstützbeins verhindert. Dadurch ist ein maximaler Schwenkwinkel festgelegt. Dabei ist auch die Ausschwenkbegrenzungsstange drehbar in dem jeweils zugeordneten Befestigungselement gelagert, wodurch sich die Lage und Ausrichtung des Langlochs je nach Wippstellung verändern kann.In the context of the invention, the Ausschwenkbegrenzung on extending in a longitudinal direction Ausschwenkbegrenzungstange, which is rotatably attached with its articulation end to a fastener and having a slot, with a fixedly connected to an associated Abstützbein stop pin extends through the slot. The slot is dimensioned so that the Abstützbein can move freely with its stop pin in the slot until the stop pin abuts the rear end of the slot and prevents further pivoting of the Abstützbeins. As a result, a maximum swing angle is set. In this case, the Ausschwenkbegrenzungsstange is rotatably mounted in the respectively associated fastening element, whereby the position and orientation of the oblong hole can change depending on the rocking position.

Als Versatzhilfsmittel im Sinne der Erfindung kommt beispielsweise eine Gleitbeschichtung des Fußendes des Abstützbeins in Betracht. Die Gleitbeschichtung setzt die Reibung zwischen Fußende und Boden so weit herab, dass dem Nutzer beim Sitzen ein sicheres Gleiten mit dem Stuhl ermöglicht ist. Als Gleitbeschichtung kommt beispielsweise ein geeigneter Stoffbezug oder dergleichen in Betracht.As an offset aid in the context of the invention, for example, a sliding coating of the foot end of Abstützbeins comes into consideration. The sliding coating reduces the friction between the foot and the floor to such an extent that the user is able to slide safely with the chair while sitting. As a lubricious coating is for example a suitable fabric reference or the like into consideration.

Bei einer bevorzugten Ausführung der Erfindung ist das Versatzhilfsmittel eine Rolle. Bei der Nutzung des Stuhls rollt die Rolle des Fußendes auf dem Boden ab und verringert so den Reibwiderstand. Dies gilt auch bei einer Kippbewegung oder beim Wippen. In der maximal ausgelenkten Stellung, in welcher die Schwenkbegrenzungsmittel ein weiteres Ausschwenken des Abstützbeins verhindern, ermöglichen die Rollen, dass der Nutzer auch in dieser maximalen Schwenkstellung, den Stuhl mit Hilfe seiner Füße verschieben kann. Dies kann für ein die Gesundheit förderndes Wohlgefühl sorgen.In a preferred embodiment of the invention, the offset aid is a role. When using the chair, the role of the foot on the floor rolls off, thus reducing the frictional resistance. This also applies to a tilting movement or when rocking. In the maximum deflected position in which the Swivel limiting means prevent further pivoting of Abstützbeins, allow the roles that the user can move in this maximum pivoting position, the chair with the help of his feet. This can provide a health-promoting sense of well-being.

Gemäß einer bevorzugten Ausgestaltung sind zwei Abstützbeine vorgesehen. Die Verwendung von zwei Abstützbeinen erhöht die Sturzsicherheit, wobei die Herstellkosten nur geringfügig erhöht sind.According to a preferred embodiment, two support legs are provided. The use of two support legs increases fall protection, whereby the production costs are only slightly increased.

Vorteilhafterweise umfassen die Schwenkbegrenzungsmittel eine Ausschwenkbegrenzung und eine Einschwenkbegrenzung, wobei die Ausschwenkbegrenzung einen maximalen und die Einschwenkbegrenzung einen minimalen Schwenkwinkel festlegen, der in einer Seitenansicht von einer Längsachse des Abstützbeins und einem gedachten von dem Drehlager des Schwenkträgers aus gefällten Lost bezüglich des besagten Drehlagers aufgespannt wird. Die Einschwenkbegrenzung begrenzt somit die Bewegung des Abstützbeins zum Stuhlbein hin. Der oben definierte minimale Schwenkwinkel ist vorteilhafterweise größer als 5 Grad. Ein vollständiges Einschwenken und somit eine Parallelstellung zwischen Abstützbein und hinterem Stuhlbein ist gemäß dieser vorteilhaften Weiterentwicklung vermieden. Jedes Abstützbein bleibt somit auf Grund der Einschwenkbegrenzung immer ein wenig ausgeschwenkt. Zerlegt man die beim Wippen von dem Schwenkträger über das Abstützbein in das Versatzhilfsmittel eingeleitete Kraft in eine lotrechte oder mit anderen Worten senkrechte Kraftkomponente und eine rechtwinklig dazu verlaufende horizontale Kraftkomponente, kann man die Wirkung der Einschwenkbegrenzung auch so beschreiben, dass diese dafür sorgt, dass in jeder Stellung des Stuhls, also auch in der Sitzstellung des Stuhls, durch das Belasten der Rückenlehne nach hinten zum Starten des Wippens, immer eine horizontale Kraftkomponente in die Versatzhilfsmittel eingeleitet wird und dieses in die gewünschte Wipprichtung bewegt. Die Einschwenkbegrenzung stellt somit sicher, dass die Abstützbeine beim Rückwärtswippen ausschwenken und nicht verkeilen oder gar in Richtung Stuhlbeins bewegt werden.Advantageously, the pivoting limiting means comprise a Ausschwenkbegrenzung and Einschwenkbegrenzung, the Ausschwenkebegrenzung set a maximum and Einschwenkbegrenzung a minimum pivot angle, which is spanned in a side view of a longitudinal axis of Abstützbeins and an imaginary from the pivot bearing of the pivot carrier from Lost precipitated with respect to said pivot bearing. The Einschwenkbegrenzung thus limits the movement of Abstützbeins towards the chair leg. The above-defined minimum swivel angle is advantageously greater than 5 degrees. A complete swinging and thus a parallel position between Abstützbein and rear chair leg is according to this advantageous Development avoided. Each support leg thus always remains slightly swung due to the Einschwenkbegrenzung. If the force introduced during rocking from the pivoting support via the support leg into the displacement aid is transformed into a vertical or in other words vertical force component and a horizontal force component extending at right angles thereto, the effect of the pivoting restriction can also be described as ensuring that in each position of the chair, including in the sitting position of the chair, by loading the backrest to the rear to start the rocking, always a horizontal force component is introduced into the displacement aid and this moves in the desired Wipprichtung. The Einschwenkbegrenzung thus ensures that the Abstützbeine swing when rocking backwards and not wedged or even moved in the direction of the chair leg.

Die Ausschwenkbegrenzung begrenzt hingegen das maximale Ausschwenken des Abstützbeins. Ist die Kippbegrenzungseinrichtung an einem Stuhl montiert, verhindert die Ausschwenkbegrenzung eine zu große Rückwärtsbewegung der Rückenlehne, so dass Stürze beim Wippen vermieden sind. In der maximal ausgeschwenkten Stellung, gewährleisten somit die hinteren Stuhlbeine und jedes Abstützbein einen sicheren Stand des Stuhls. Selbst in dieser Stellung ermöglichen die Versatzhilfsmittel, dass ein Nutzer den Stuhl verschieben kann.In contrast, the swivel limitation limits the maximum swiveling out of the support leg. If the Kippbegrenzungseinrichtung mounted on a chair, the Ausschwenkbegrenzung prevents excessive backward movement of the backrest, so that falls are avoided when rocking. In the maximum swung-out position, thus ensuring the rear chair legs and each Abstützbein a secure state of the chair. Even in this position, the offset tools allow a user to move the chair.

Die Einschwenkbegrenzung umfasst vorteilhafterweise wenigstens einen an einem Befestigungselement ausgebildeten Anschlag, an dem ein fest mit einem zugeordneten Abstützbein verbundener Anschlagbolzen bei Erreichen des minimalen Schwenkwinkels anschlägt.The Einschwenkbegrenzung advantageously comprises at least one formed on a fastener stop on which abuts a fixedly connected to an associated Abstützbein stop pin upon reaching the minimum pivot angle.

Gemäß einer vorteilhaften Ausgestaltung sind zwei Abstützbeine vorgesehen, die an zwei voneinander abgewandten Bereichen des Schwenkträgers angeordnet sind. Gemäß dieser Ausführung der Erfindung sind lediglich zwei Abstützbeine vorgesehen, die an voneinander abgewandten Enden des Schwenkträgers angeordnet sind. Die Abstützbeine weisen somit einen möglichst großen Abstand voneinander auf, so dass eine hohe Stabilität bereitgestellt ist. Dabei bleibt die Konstruktion der Kippbegrenzungseinrichtung einfach und daher kostengünstig.According to an advantageous embodiment, two support legs are provided, which are arranged on two mutually remote areas of the pivot carrier. According to this embodiment of the invention, only two support legs are provided, which are arranged at opposite ends of the pivot support. The support legs thus have the greatest possible distance from each other, so that a high stability is provided. The design of the Kippbegrenzungseinrichtung remains simple and therefore inexpensive.

Gemäß einer diesbezüglichen zweckmäßigen Weiterentwicklung sind die Abstützbeine so an den Befestigungselementen gehalten, dass die Abstützbeine sich in der befestigten Stellung direkt hinter den hinteren Stuhlbeinen erstrecken. Jedes hintere Stuhlbein liegt somit nach der Montage der Befestigungselemente in einer Ebene mit einem Abstützbein. Hierdurch ist die Stabilität und Sturzsicherheit noch weiter erhöht.According to an appropriate further development in this regard, the support legs are held on the fasteners that the support legs extend in the mounted position directly behind the rear chair legs. Each rear chair leg thus lies after the mounting of the fasteners in a plane with a support leg. As a result, the stability and fall protection is further increased.

Gemäß einer zweckmäßigen Weiterentwicklung des erfindungsgemäßen Stuhls ist jedes Befestigungselement fest an einem hinteren Stuhlbein montiert. Das Befestigungselement ist beispielsweise ein ebenes Montageblech, das in einer Seitenansicht das Stuhlbein nach hinten, also in Richtung der Rückwärtsschwenkbewegung, überragt. In dem das Stuhlbein überragenden Halteabschnitt ist beispielsweise ein Drehlager in Gestalt einer einfachen Durchgangsbohrung ausgebildet, durch welche sich der Schwenkträger mit einem seiner freien Enden erstreckt. Dabei weist das freie Ende des Schwenkträgers beispielsweise ein Außengewinde auf, in welches eine Mutter eingreift, die ein Herausgleiten des Schwenkträgers aus der Durchgangsbohrung des Tragabschnitts verhindert.According to an expedient development of the chair according to the invention, each fastening element is firmly mounted on a rear chair leg. The fastening element is, for example, a planar mounting plate which, in a side view, projects beyond the chair leg toward the rear, that is to say in the direction of the rearward pivoting movement. In which the chair leg projecting holding portion, for example, a rotary bearing in the form of a simple through hole is formed, through which the pivot support extends with one of its free ends. In this case, the free end of the pivot support, for example, an external thread, in which engages a nut which prevents slipping out of the pivot support from the through hole of the support portion.

Gemäß einer weiteren Ausgestaltung des erfindungsgemäßen Stuhls sind die Befestigungselemente so montiert, dass die Abstützbeine in jeder Kippstellung des Stuhls mit ihrem Fußende den Boden kontaktieren. Gemäß dieser vorteilhaften Ausgestaltung der Erfindung kommt zu einem ständigen Kontakt zwischen Abstützbein und Boden, so dass für ein maximales Maß an Sicherheit gesorgt ist.According to a further embodiment of the chair according to the invention, the fastening elements are mounted so that the support legs contact the ground in each tilted position of the chair with its foot. According to this advantageous embodiment of the invention comes to a constant contact between the support leg and ground, so that a maximum level of security is ensured.

Weitere zweckmäßige Ausgestaltungen und Vorteile der Erfindung sind Gegenstand der nachfolgenden Beschreibung von Ausführungsbeispielen der Erfindung unter Bezug auf die Figuren der Zeichnung, wobei gleiche Bezugszeichen auf gleich wirkende Bauteile verweisen und wobei

Further expedient embodiments and advantages of the invention are the subject of the following description of embodiments of the invention with reference to the figures of the drawing, wherein like reference numerals refer to like-acting components and wherein
FIG. 1
an embodiment of the invention Kippbegrenzungseinrichtung in normal position and
FIG. 2
the Kippbegrenzungseinrichtung of FIG. 1 show in a maximum deflected position.

Figur 1 zeigt die Kippbegrenzungseinrichtung 1 gemäß der vorliegenden Erfindung in einer perspektivischen Darstellung. Es ist erkennbar, dass die Kippbegrenzungseinrichtung 1 zwei Befestigungselemente 2 aufweist, die jeweils an einem hinteren Stuhlbein 3 eines nicht vollständig dargestellten Stuhls montiert sind. Dabei ist jedes Befestigungselement 2 als flaches Blech ausgebildet, das mit Befestigungsmitteln 4 wie beispielsweise Schrauben oder Nieten fest mit dem hinteren Stuhlbein 3 verbunden ist. In einer Seitenansicht überragt jedes Befestigungselement 2 das Stuhlbein 3 nach hinten, also in Richtung einer Rückwärtskippbewegung hin, so dass das hintere Stuhlbein 3 von einem Halteabschnitt 5 eines jeden Befestigungselements 2 in Rückwärtsrichtung überragt ist. In dem Halteabschnitt 5 ist an seinem oberen Ende eine Durchgangsbohrung 17 als Drehlager eingebracht, durch das das freie Ende eines Schwenkträgers 6 hindurch ragt, der sich in einer Querrichtung erstreckt. Das besagte freie Ende ist mit einem Außengewinde versehen, das in ein Innengewinde einer Überwurfmutter 7 eingreift. Die Überwurfmutter 7 ist nur so fest aufgeschraubt, dass ein Herausgleiten des Schwenkträgers 6 aus dem Befestigungsabschnitt 5 in Querrichtung zwar vermieden, ein Vorwärts- und Rückwärtsschwenken des Schwenkträgers 6 in dem Drehlager 17 jedoch ermöglicht ist. FIG. 1 shows the Kippbegrenzungseinrichtung 1 according to the present invention in a perspective view. It can be seen that the Kippbegrenzungseinrichtung 1 has two fasteners 2, which are each mounted on a rear chair leg 3 of a not fully illustrated chair. In this case, each fastening element 2 is formed as a flat sheet, which is connected with fastening means 4 such as screws or rivets fixed to the rear chair leg 3. In a side view, each fastening element 2 projects beyond the chair leg 3 towards the rear, ie in the direction of a backward tilting movement, so that the rear chair leg 3 is surmounted by a retaining section 5 of each fastening element 2 in the rearward direction. In the holding portion 5, a through hole 17 is inserted as a pivot bearing at its upper end, through which the free end of a pivot support 6 protrudes, which extends in a transverse direction. The said free end is provided with an external thread, which engages in an internal thread of a union nut 7. The union nut 7 is screwed only so tightly that a sliding out of the pivot support 6 from the attachment portion 5 in the transverse direction while avoiding a forward and backward pivoting of the pivot support 6 in the pivot bearing 17, however, is possible.

Ferner ist ein Abstützbein 8 erkennbar, das mit seinem Befestigungsende 9 fest mit dem Schwenkträger 6 verbunden ist. An seinem vom Befestigungsende 9 abgewandten Fußende 10 ist jedes Abstützbein 8 mit einer Rolle 11 ausgerüstet. Die Rolle 11 steht unabhängig von der Kippstellung des Stuhls in ständigem Kontakt mit einem Boden 20, so dass das Abstützbein 8 beim Wippen fortwährend auf dem Boden 20 abrollt und somit den gewünschten Sturzschutz bereitstellt. Als Ausschwenkbegrenzung ist eine Ausschwenkbegrenzungsstange 12 vorgesehen, die sich in einer Längsrichtung erstreckt. Die Ausschwenkbegrenzungsstange 12 ist mit ihrem Anlenkende 13 drehbar in dem jeweils zugeordneten Befestigungselement 2 und insbesondere dessen Halteabschnitt 5 gelagert. Darüber hinaus verfügt die Ausschwenkbegrenzungsstange 12 an ihrer vom Befestigungsende 13 abgewandten Seite über ein Langloch 14, durch das sich ein Anschlagbolzen 15 erstreckt, der fest mit dem Abstützbein 8 verbunden ist. Eine Sicherungsmutter 16 schützt vor dem Herausgleiten des Anschlagbolzens 15 aus dem Langloch 14 in Querrichtung, wobei jedoch ein Verschieben des Anschlagbolzens 15 in dem Langloch 14 ermöglicht ist. Der Anschlagbolzen 15 überragt in der besagten Querrichtung das Befestigungselement 2, so dass ein minimaler Schwenkwinkel definiert ist, der in einer Seitenansicht von einer figürlich nicht dargestellten Längsachse des Abstützbeins 8 und einem vom Drehlager 17 aus gefällten Lot, also einer senkrecht zum Boden 20 verlaufenden Achse, bezüglich des besagten Drehlagers 17 aufgespannt wird. Mit anderen Worten ist das Abstützbein 8 niemals parallel zum hinteren Stuhlbein 3 ausgerichtet, so dass beim Wippen immer eine horizontale Kraftkomponente in das Fußende 10 eingeleitet wird. Ein Verklemmen des Abstützfußes 8 ist auf diese Weise vermieden. Anschlagbozen 15 und Befestigungsabschnitt bilden somit eine Einschwenkbegrenzung aus.Further, a support leg 8 can be seen, which is connected with its attachment end 9 fixed to the pivot support 6. At its end remote from the fastening end 9 foot 10 each Abstützbein 8 is equipped with a roller 11. The roller 11 is independent of the tilted position of the chair in constant contact with a floor 20, so that the support leg 8 continuously rolls on the ground 20 during rocking and thus provides the desired fall protection. As Ausschwenkbegrenzung Ausschwenkbegrenzungstange 12 is provided which extends in a longitudinal direction. The Ausschwenkbegrenzungstange 12 is rotatably mounted with its articulation end 13 in the respective associated fastener 2 and in particular its holding portion 5. In addition, the Ausschwenkbegrenzungstange 12 has at its side remote from the mounting end 13 side of a slot 14 through which a stop pin 15 extends, which is fixedly connected to the support leg 8. A lock nut 16 protects against slipping out of the stop pin 15 from the slot 14 in the transverse direction, but a displacement of the stop pin 15 in the slot 14 is made possible. The stop pin 15 projects beyond the fastening element 2 in the said transverse direction, so that a minimum pivoting angle is defined, which in a side view is not shown by a longitudinal axis of the support leg 8 and a perpendicular from the pivot bearing 17, ie an axis perpendicular to the base 20 , is clamped with respect to said pivot bearing 17. In other words, the support leg 8 is never aligned parallel to the rear chair leg 3, so that during rocking always a horizontal force component is introduced into the foot end 10. Jamming the Stützfußes 8 is avoided in this way. Stop bolts 15 and attachment portion thus form a Einschwenkbegrenzung.

Figur 2 zeigt die Kippbegrenzungseinrichtung 1 gemäß Figur 1 in einer maximal ausgelenkten Stellung, in welcher der Anschlagbolzen 15 an dem Ende des Langloches 14 anschlägt. Der Anschlagbolzen 15 bildet mit dem Langloch 14 daher eine Ausschwenkbegrenzung aus, die einen maximalen Schwenkwinkel festlegt, der natürlich ebenfalls zwischen der besagten Längsachse des Abstützbeins 8 und dem vom Drehlager 17 aus gefällten Lot bezüglich des besagten Drehlagers 17 aufgespannt wird. Mit anderen Worten ist das Wippen mit dem Stuhl auf einen maximalen Schwenkwinkel begrenzt. In dieser in Figur 2 gezeigten Stellung ermöglichen die Rollen 11 ein weiteres Verschieben des Stuhls. FIG. 2 shows the Kippbegrenzungseinrichtung 1 according to FIG. 1 in a maximum deflected position in which the stop pin 15 abuts the end of the elongated hole 14. The stop pin 15 forms with the slot 14 therefore a Ausschwenkbegrenzung from, which defines a maximum pivoting angle, which of course also between the said longitudinal axis of Abstützbeins 8 and the precipitated from the pivot bearing 17 solder with respect to said pivot bearing 17 is clamped. In other words, the rocker with the chair is limited to a maximum swing angle. In this in FIG. 2 shown position, the rollers 11 allow further displacement of the chair.

Auf diese Weise kann der Nutzer seinem Bewegungsdrang nachgehen, ohne dass eine Sturzgefahr besteht. Dies sorgt für Spaß, ist sicher und gesund und entlastet gleichzeitig möglicherweise vorhandenes Aufsichtspersonal.In this way, the user can pursue his urge to move without the risk of falling. This ensures fun, is safe and healthy and relieves at the same time possibly existing supervisors.
