Description

"Arbeitsdrehstuhl mit einem, durch Keilnut höhenverstell-"Industrial swivel chair with a height-adjustable

baren, nicht drehbaren Fußringeloment." Die Erfindung betrifft einen Arbeitsdrehstuhl mit einem, durch Keilnut höhenverstellbaren, nicht drehbaren Fußringelement, das synchron mit der Keilnut-Sitzhöhenverstellung mitverstellt wird.ble, non-rotatable Fußringeloment. "The invention relates to a Industrial swivel chair with a non-rotatable foot ring element that is height-adjustable by means of a keyway, which is adjusted synchronously with the keyway seat height adjustment.

In der Industrie werden z.T Arbeitsdrehstühle mit eiller Fußstütze verwendet, die unter der Sitzfläche angebracht ist ud mit dieser alle Dreh- und Steuerbewegungen ausfahrt.In industry, swivel work chairs with a footrest are sometimes used used, which is attached under the seat ud with this all rotating and Control movements exit.

Das hat folgende Nachteile: Der Sitzende wird in eine bestimmte starre Sitzposition gezwungen, d.h., er muli beide Füße nebeneinander auf die Fußstütze stellen. Will er nun eine Drehbewegung ausführen, muß er mit den Füßen Bodenkontakt suchen und sich abstoßen, oder aber sich mit den Händen an einer Werkbank oder Maschine in die gewünschte Position ziehen oder drücken.This has the following disadvantages: The sitter becomes rigid in a certain way Forced sitting position, i.e. he mules both feet next to each other on the footrest place. If he now wants to make a turning movement, his feet must be in contact with the ground looking for and pushing yourself off, or with your hands on a workbench or machine Drag or press to the desired position.

Es gibt auch Arbeitsdrehstühle die mit Fußringelement versehen sind, die an den Standsäulen höhenverstellbar und nicht drehbar angebracht sind.There are also swivel work chairs with a foot ring element, which are height-adjustable and non-rotatable attached to the columns.

Muß aus arbeitst echnischen Gründen eine Sitzhöhenverstellung, z.B. nach oben, vorgenommen werden, ist immer eine separate Nachjustierung des Fußringelementes notwendig, um den optimalen Abstand zwischen Sitzfläche und Fußringelement wieder herzustellen.Does a seat height adjustment have to be carried out for technical reasons, e.g. upwards, is always a separate readjustment of the foot ring element necessary to restore the optimal distance between the seat and the foot ring element to manufacture.

Der Erfindung liegt die Aufgabe zugrunde einen Arbeitsdrehstuhl zu schaffen, bei dem die einmal optimal eingestellte Sitzposition, d.h. der richtige Abstand zwischen nicht drehbaren Fußringelement und drehbarer Sitzfläche je nach Größe des Draufsitzenden, bei der Verstellung der Sitzhöhe erhalten bleibt.The invention is based on the object of a work swivel chair in which the optimally adjusted sitting position, i.e. the correct one Distance between non-rotatable foot ring element and rotatable seat depending on Size of the person sitting on top, when the seat height is adjusted, is retained.

Deshalb wird, gemäß der Erfindung nach beigefügter Zeichnung für den oben genannten Arbeitsdrehstuhl vorgeschlagen, das axial bewegliche Führungsrohr 1 in der Standsäule 2 mit einem durchgehenden Langloch 3 zu versehen. Ein Stift 4 wird quer durch die Standsäule 2 und das Führungsrohr 1 geführt. Durch diese Anordnung bleibt die axiale Beweglichkeit des Führungsrohres 1 erhalten (Tiefenfederung) und wird gleichzeitig gegen Drehung gesichert. In dem Führungsrohr 1 sitzt axial beweglich der Keilnutbolzen 5 der mit zwei Keilnuten 6 und 7 versehen istv Die Klemmschraube 8 die zur Arretierung der Sitzhöhenverstellung dient, presst in Klemmstellung den Keilnutbolzen 5 in der Keilnut 6 im Führungsrohr 1 fest. Die Keilnut 7 ist im Keilnutbolzen 5 erfindungsgemäß um 1800 verdreht angeordnet. Die Klemmschraube 9 ist durch das Tragrohr 10 und den Klemmring 11 geführt. Das Tragrohr 10 ist mit dem Fußringelement 12 durch Schweißung unlösbar zu einer Einheit verbunden und vertikal beweglich über dem Keilnutbolzen 5 angeordnet. Die Klemmschraube 9 arretiert das Tragrohr 10 mit dem Fußringelement 12 sicher in der Keilnut 7 im Keilnutbolzen 5 . Oben über dem Keilnutbolzen 5 ist der Sitzträger 13 mit der Buchse 14 drehbar angebracht und gesichert. Wird die Klemmschraube 9 gelöst kann man das Fußringelement 12 problemlos vertikal verstellen und den optimalen Abstand zur Sitzfläche herstellen. Muß die Sitzhöhe verstellt werden, kann man nach Lösen der Klemmschraube 8 Sitzfläche und Fußringelement 12 zusammen verstellen. Der einmal eingestellte Abstand zwischen Sitzfläche und Fußringelement 12 bleibt erhalten.Therefore, according to the invention according to the accompanying drawings for proposed above swivel work chair, the axially movable guide tube 1 to be provided in the vertical column 2 with a continuous elongated hole 3. A pen 4 is guided transversely through the vertical column 2 and the guide tube 1. Through this arrangement the axial mobility of the guide tube 1 is retained (depth suspension) and is secured against rotation at the same time. In the guide tube 1 sits axially movable the keyway bolt 5 which is provided with two keyways 6 and 7v the clamping screw 8, which is used to lock the seat height adjustment, presses the in the clamping position Keyway bolt 5 in the keyway 6 in the guide tube 1. The keyway 7 is in the keyway bolt 5 arranged rotated by 1800 according to the invention. The clamping screw 9 is through the Support tube 10 and the clamping ring 11 out. The support tube 10 is with the foot ring element 12 non-detachably connected to a unit by welding and vertically movable over the keyway bolt 5 arranged. The clamping screw 9 locks the support tube 10 with it the foot ring member 12 securely in the keyway 7 in the keyway bolt 5. Up above that With the keyway bolt 5, the seat support 13 is rotatably mounted and secured with the bushing 14. If the clamping screw 9 is loosened, the foot ring element 12 can be moved vertically without any problems adjust and create the optimal distance to the seat. Must be the seat height can be adjusted, you can after loosening the clamping screw 8 seat and foot ring element 12 adjust together. The once set distance between the seat and Foot ring element 12 is retained.
