Description

Stuhl  chair
Die Erfindung betrifft einen Stuhl gemäß dem Oberbegriff des Patentanspruchs 1. The invention relates to a chair according to the preamble of patent claim 1.
Ein Stuhl der eingangs genannten Art ist aus dem Dokument DE 90 11 246 Ul bekannt. Dieser Stuhl besteht aus einer Sitzfläche und einem mit der Sitzfläche verbundenen und über eine Schwenkachse verschwenkbaren Widerlagerelement, das in einer ersten Schwenkposition als Rückenlehne für einen auf der Sitzfläche sitzenden Benutzer und in einer zweiten Schwenkposition als Abstützfläche für einen sich an der Abstützfläche im Stehen abstützenden Benutzer verwendbar ausgebildet ist. Bei diesem Stuhl ist die Sitzfläche zur Realisierung der beiden Schwenkpositionen mittig geteilt bzw. geschlitzt ausgebildet (vergleiche insbesondere Schutzanspruch 1 und Figur 3 in DE 90 11 246 Ul) . A chair of the type mentioned is known from the document DE 90 11 246 Ul. This chair consists of a seat and a connected to the seat and pivotable about a pivot axis abutment element, which in a first pivot position as a backrest for a seated on the seat user and in a second pivot position as a support surface for a standing on the support surface user is designed usable. In this chair, the seat for the realization of the two pivot positions is divided centrally or slotted formed (see in particular protection claim 1 and Figure 3 in DE 90 11 246 Ul).
Der Erfindung liegt die Aufgabe zugrunde, einen Stuhl der eingangs genannten Art zu verbessern. Insbesondere soll ein Stuhl geschaffen werden, bei dem die beiden genannten Schwenkpositionen ebenfalls realisierbar sind, allerdings ohne dass die Sitzfläche geschlitzt ausgeführt sein muss. The invention has for its object to improve a chair of the type mentioned. In particular, a chair is to be created in which the two said pivotal positions are also feasible, but without the seat must be made slotted.
Diese Aufgabe ist mit einem Stuhl der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst. This object is achieved with a chair of the type mentioned by the features listed in the characterizing part of patent claim 1.
Nach der Erfindung ist also vorgesehen, dass die Schwenkachse des Widerlagerelements oberhalb der Sitzfläche angeordnet ist. Mit anderen Worten zeichnet sich die erfindungsgemäße Lösung somit insbesondere dadurch aus, dass die Schwenkachse nicht mehr unterhalb der Sitzfläche angeordnet und damit eine Teilung der Sitzfläche entbehrlich ist. According to the invention, it is thus provided that the pivot axis of the abutment element is arranged above the seat surface. In other words, the solution according to the invention is characterized in particular by the fact that the pivot axis is no longer disposed below the seat and thus a division of the seat is unnecessary.
Andere vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Patentansprüchen. Other advantageous developments emerge from the dependent claims.
Der Vollständigkeit halber wird noch auf das weiter abliegende Dokument DE 10 2013 110 674 B3 hingewiesen, aus dem ebenfalls ein Stuhl mit einer verschwenkbaren Rückenlehne bekannt ist. Bei dieser Lösung ist auf der sitzflächenabgewandten Seite der Rückenlehne eine sphärische Therapiesitzfläche angeordnet, die allerdings - wie schon die eigentliche Sitzfläche - ebenfalls nur zum (geringfügig erhöhten) Sitzen dient. For the sake of completeness, reference is made to the more distant document DE 10 2013 110 674 B3, from which a chair with a pivotable backrest is also known. In this solution, a spherical therapy seat surface is arranged on the seat side facing away from the backrest, but - as the actual seat - also serves only for (slightly elevated) seats.
Der erfindungsgemäße Stuhl einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels näher erläutert. The chair according to the invention including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of a preferred embodiment.

The user's feet are on the side of the trailing edge 1.2 of the seat 1.
In den Figuren 2 und 4 ist das Widerlagerelement 3 in der zweiten Schwenkposition nahe der Vorderkante 1.1 der Sitzfläche 1 positioniert. Die Armlehnen 5 sind dann ungefähr senkrecht verlaufend ausgerichtet. Je nach dem, wie das Widerlagerelement 3 in dieser zweiten Schwenkposition um seine Drehachse 6 gedreht ist, ergeben sich die folgenden drei Möglichkeiten : In FIGS. 2 and 4, the abutment element 3 is positioned in the second pivoting position near the front edge 1.1 of the seat surface 1. The armrests 5 are then aligned approximately perpendicular. Depending on how the abutment element 3 is rotated about its axis of rotation 6 in this second pivoting position, the following three possibilities arise:
Wenn der Benutzer steht, kann er sich mit seinem Gesäß an der Hauptwiderlagerfläche des Widerlagerelements 3 abstützen bzw. auf dieser im Grunde stehend sitzen. Wenn sich der Benutzer gewissermaßen mit gehockten Beinen mit seinen Schienbeinen auf die Sitzfläche 1 setzt, so dass seine Knie an der Vorderkante 1.1 und seine Füße an der Hinterkante 1.2 der Sitzfläche 1 positioniert sind, kann er sich mit seinen Armen auf der entsprechend gedrehten Hauptwiderlagerfläche des Widerlagerelements 3 abstützen. If the user stands, he can rest with his buttocks on the main abutment surface of the abutment member 3 and sit on this basically standing. When the user places his legs on the seat 1 with his legs so to speak, so that his knees are positioned at the front edge 1.1 and his feet at the rear edge 1.2 of the seat 1, he can rest his arms on the correspondingly rotated main abutment surface of the seat Support abutment element 3.
Wenn der Benutzer seine Beine durch die zwischen Sitzfläche 1 und Widerlagerelement 3 definierte Öffnung hindurchsteckt und dann mit seinem Gesäß auf der Sitzfläche 1 sitzt, so dass seine Füße auf der Seite der Vorderkante 1.1 der Sitzfläche 1 positioniert sind, kann er sich mit seinen Armen auf der entsprechend gedrehten Hauptwiderlagerfläche des Widerlagerelements 3 abstützen. When the user pushes his legs through the opening defined between seat 1 and abutment element 3 and then sits with his buttocks on the seat 1, so that his feet are positioned on the side of the front edge 1.1 of the seat 1, he can with his arms on the correspondingly rotated main abutment surface of the abutment element 3 are supported.
Der erfindungsgemäße Stuhl funktioniert also wie folgt: The chair according to the invention thus works as follows:
Möchte der Benutzer des Stuhls beispielsweise von einer sitzenden in eine Stehposition wechseln, so klappt er das Widerlagerelement 3 um die Schwenkachse 2 nach oben, dreht den Stuhl und kann sich nun im Stehen an das Widerlagerlement 3 anlehnen . For example, if the user of the chair wishes to change from a sitting to a standing position, he folds up the abutment element 3 about the pivot axis 2, turns the chair and can now lean against the abutment element 3 when standing.
Bei der dargestellten Ausführungsform kann dabei das U-förmige Widerlagerelement 3 während dieses Vorgangs um die Drehachse 6 gedreht werden, so dass der Benutzer von der von ihm bevorzugten Seite des Widerlagerelements 3 gestützt wird. In the illustrated embodiment, during this process, the U-shaped abutment element 3 can be rotated about the axis of rotation 6, so that the user is supported by the preferred side of the abutment element 3.
Noch genauer gesagt, wird das Einstellen der gewünschten Sitzoder Stehposition vom Benutzer je nach Ausführungsform des erfindungsgemäßen Stuhls durch das Verschwenken des Widerlager- elements 3 um die Schwenkachse 2 und/oder das Drehen des Widerlagerelements 3 um die Drehachse 6 und/oder das Drehen des Stuhls an sich, oder seines oberen Teils (ab der Sitzfläche) um die Längsachse des Vertikalträgerelements 7 herum, vorgenommen . More specifically, the adjustment of the desired sitting or standing position by the user depending on the embodiment of the chair according to the invention by the pivoting of the abutment elements 3 about the pivot axis 2 and / or the rotation of the abutment member 3 about the axis of rotation 6 and / or the rotation of the chair itself, or its upper part (from the seat) about the longitudinal axis of the vertical support member 7 made around.
