Description
Federnder Drehstuhl. Vorliegende Erfindung betrifft einen federn den Drehstuhl mit einer verschieb- und dreh baren Tragspindel und daran befestigtem Sitz, sowie einem mit der Tragspindelhülse verbundenem Fussstück, bei welchem der federnde Teil des Stuhles durch Blattfedern gebildet ist.
Ein Ausführungsbeispiel des Erfindungs gegenstandes mit dem federnden Teil als Fussstück ist in der Zeichnung dargestellt, und zwar zeigt: Fig. 1 eine Seitenansicht des Stuhles, Fig. 2 einen Schnitt durch das Fussstück in etwas grösserem 11lassstabe, Fig. ss eine Draufsicht des Fussstückes, Fig. 4 einen Vertikalschnitt durch die Be festigungsvorrichtung der Rücklehne am Trag= band, Fig. 5 dasselbe im Horizontalschnitt.
In dem gezeichneten Ausführungsbeispiel ist 1 das aus dem kreuzförmig angeordneten Blattfedern 1a und 1b bestehende Fussstück. Dieses ist mit der Tragspindelhülse 2 durch ein nabenartiges Verbindungsglied 3 verbun den, indem dasselbe einerseits mit dem Fuss stück vernietet ist und anderseits das untere Ende der Tragspindelhülse nabenartig um schliesst.
In der Spindelhülse 2 ist die Tragspindel 4 verschiebbar eingesteckt, wobei zum Festhal ten desselben in der gewünschten Höhenlage ein Gesperre bekannter Art mit nicht ge zeichnetem Betätigungshebel dient. Am obern Ende der Tragspindel 4 ist der Sitz 5 be festigt. Am untern Ende der Spindelhülse 2 ist ein Gummipuffer 10 angeordnet, welcher die Senkbewegung des Sitzes begrenzt, so dass die Federn nicht infolge übermässiger Durchbiegung brechen können.
Die Rücklehne 6 des Stuhles ist höhen verschiebbar und mittelst eines Exzenterhe- bels 7 in beliebiger Höhe feststellbar auf einem Tragband 8 angebracht, dessen wag rechter Teil unter dem Sitz 5 wagrecht aus ziehbar und mittelst eines Exzenterhebels 9 feststellbar befestigt ist, so dass die Rücklehne in ihrem Quer- und Höhenabstand vom Sitz der den Stuhl benützenden Person ange passt werden kann.
Ausserdem ist die Rück lehne 6 mittelst eines mit ihr fest verbun denen Halters 11 an einem das Tragband 8 umfassenden, den Exzenterhebel 7 haltenden Gabelstück 12 um eine horizontale Achse 13 drehbar angeordnet, zum Zwecke, je nach der Stellung des Sitzenden eine zum Trag band 8 geneigte Lage der Rücklehne zu ermöglichen.
Statt der zwei kreuzförmigen Blattfedern können auch drei oder mehr sternförmig an geordnete Blattfedern verwendet werden.
Statt das Fussstück federnd auszubilden, kann der federnde Teil auch zwischen Sitz und Tragspindel angeordnet sein.

At the upper end of the support spindle 4, the seat 5 is fastened be. At the lower end of the spindle sleeve 2, a rubber buffer 10 is arranged, which limits the lowering movement of the seat so that the springs cannot break as a result of excessive deflection.
The backrest 6 of the chair can be moved in height and can be fixed at any height by means of an eccentric lever 7 on a carrier tape 8, the wag right part of which is horizontally pulled out from under the seat 5 and secured by means of an eccentric lever 9 so that the backrest is in their transverse and vertical distance from the seat of the person using the chair can be adjusted.
