Description

Die Erfindung betrifft einen Stuhl, insbesondere Drehstuhl und verfahrbaren Roll-Drehstuhl mit Arm­lehnen.The invention relates to a chair, in particular swivel chair and movable wheel swivel chair with armrests.

Bei Computer-, Schreibmaschinen-, und auch Datenver­arbeitungs-Arbeitsplätzen hat es sich gezeigt, daß weder übliche Armlehnen an den Drehstühlen noch Handauflagen an den Arbeitstischen für eine richtige und ermüdungsfreie Arbeit besonders geeignet sind.In the case of computer, typewriter and data processing workstations, it has been shown that neither conventional armrests on the swivel chairs nor handrests on the work tables are particularly suitable for correct and fatigue-free work.

Der Erfindung liegt die Aufgabe zugrunde, einen für derartige Arbeitsplätze geeigneten Stuhl zu schaffen. Zur Lösung dieser Aufgabe ist der erfindungsgemäße Stuhl dadurch gekennzeichnet, daß jede Armlehne ausschließlich als Ellenbogenstütze eine der Größe eines Ellenbogens angepaßte Stützfläche hat, in der lediglich dem Ellenbogengelenk eine Unterstützung findetThe invention has for its object to provide a chair suitable for such workplaces. To achieve this object, the chair according to the invention is characterized in that each armrest has a support surface adapted to the size of an elbow exclusively as an elbow support, in which only the elbow joint is supported

Jede Stützfläche hat vorzugsweise die Form eines kreisförmigen Polsters mit einem Durchmesser zwischen 10 und 18 cm, vorzugsweise 15 cm. Die Stützfläche kann auch die Form einer seitlich ein­seitig offenen Stützmulde haben.Each support surface preferably has the shape of a circular cushion with a diameter between 10 and 18 cm, preferably 15 cm. The support surface can also have the shape of a support trough which is open on one side.

Gemäß weiterer Erfindung ist vorgesehen, die Ellenbogenstütze um eine Vertikalachse drehbar zu gestalten und sie gegebenenfalls an höhenverstell­baren Bügeln bzw. Tragbügeln zu befestigen. Jeder Tragbügel kann vorzugsweise seitlich nach innen und außen verstellbar sein; der einzelne Tragbügel kann vorzugsweise weiterhin um eine unterhalb der Stuhl-Sitzfläche liegende, vorzugsweise im Bereich der Stuhl-Hauptachse liegende Achse nach vorn und hinten verschenkbar sein.According to a further invention, it is provided that the elbow support can be rotated about a vertical axis and, if necessary, attached to height-adjustable brackets or carrying brackets. Each bracket can preferably be laterally adjustable inwards and outwards; the individual support bracket can preferably also be able to be given away forwards and backwards about an axis lying below the chair seat surface, preferably in the region of the main chair axis.

Gemäß weiterer Erfindung ist vorgesehen, daß jede Armlehne an einem Armlehnenträger um mindestens zwei, vorzugsweise drei, Vertikalachsen drehbar befestigt ist, wobei insbesondere jede Armlehne als Ellenbogenstütze eine der Größe eines Ellenbogens angepaßte Stützfläche hat, in der lediglich das Ellenbogengelenk eine Unterstützung findet.According to a further invention it is provided that each armrest is rotatably attached to an armrest support about at least two, preferably three, vertical axes, in particular each armrest as an elbow support having a support surface adapted to the size of an elbow, in which only the elbow joint is supported.

Dadurch, daß jede Armlehne um zwei, vorzugsweise drei Achsen drehbar ist, ist gewährleistet, daß unabhängig von der Körpergröße und den Körpermaßen einer auf dem Stuhl sitzenden Person und weitgehend auch unabhängig von der Sitzposition, die diese Person auf dem Stuhl einnimmt, die Armlehne bzw. die Ellenbogenstütze an jedem gewünschten bzw. erforderlichen Punkt plaziert werden kann, wodurch das bisherige Drehen bzw. Gleiten des Ellenbogens auf der Armlehne bzw. Ellenbogenstütze und damit auch das "Radieren" der Bekleidung bzw. Ärmel ent­fällt.The fact that each armrest is rotatable about two, preferably three axes, ensures that regardless of body size and body dimensions a person sitting on the chair and largely regardless of the sitting position that person occupies in the chair, the armrest or elbow support can be placed at any desired or required point, whereby the previous rotation or sliding of the elbow on the Armrest or elbow support and thus also the "erasing" of clothing or sleeves is eliminated.

Bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen, und zwar insbesondere im Patentanspruch 3, behandelt.Preferred embodiments of the invention are dealt with in the subclaims, in particular in claim 3.
