Description
Drehstuhl mit Höhenverstellung ======================== Die Erfindung betrifft einen Drehstuhl mit Höhenverstellung durch Gewindespindel und 3 Telescoprohren zur Fuhrung der beim Aufsitzen nach unten federnden Stuhlplatte.Swivel chair with height adjustment ========================= The invention relates to a swivel chair with height adjustment by means of a threaded spindle and 3 telescopic tubes for guiding the chair plate, which springs down when sitting on.
Drehstühle mit HUhenverstellung durch eine Gewindespindel sind bekannt.Sie haben den Nachteil,daß man die Stuhlplatte drehen muß,wenn eine Höhenverstellung entsprechend der Gewindesteigung eintreten soll.Swivel chairs with height adjustment by means of a threaded spindle are known. They have the disadvantage that you have to turn the chair plate when adjusting the height should occur according to the thread pitch.
Das Neue der Erfindung ist,daß die Gewindespindel für die Höhenverstellung durch ein Kegelradgetriebe gedreht wird'das durch eine Kurbel betätigt wird,die vom Sitzenden aus leicht erreichbar ist,da sie sich an der Seite der Stuhlplatte-befindet.The novelty of the invention is that the threaded spindle for height adjustment rotated by a bevel gearbox that is operated by a crank that is easily accessible from the seated person, as it is located on the side of the chair plate.
Das durch die Gewindespindel hoch und tief bewegte mittlere Telescoprohr,an dem ein Querbalken für die Stuhlplattenlagerung befestigt ist,wird in jeder Höhenlage durch das äußere und innere Telescoprohr geführt,wobei zwischen dem inneren und äußeren Rohr die Aufsitzfeder angeordnet ist.The middle telescopic tube moved up and down by the threaded spindle to which a crossbar is attached for the chair plate storage, is at every height guided through the outer and inner telescope tube, with between the inner and outer tube the Aufsitzfeder is arranged.
An dem Querbalken des inneren Telescoprohree,an dem am vorderen Emde die Stuhlplatte schwenkbar gelagert ist,ist am hinteren Ende ein Träger befestigt,an dessen unterem Ende das innere Telescoprohr befestigt ist,während das äußere Telescoprohr an der Stuhlplatte beweglich gelagert ist.Am oberen Teil des äußeren Telescoprohres gefindet sich das Kegelradgetriebe für den Antrieb der Hubspindel,so daß vom Sitzenden aus das hintere Ende der Stuhlplatte mit Rücklehne nach oben und unten gewegt werden kann.On the crossbar of the inner Telescoprohree, on the one on the front Emde the chair plate is pivotably mounted, a carrier is attached to the rear end the lower end of which the inner telescope tube is attached, while the outer telescope tube is movably mounted on the chair plate. On the upper part of the outer telescopic tube The bevel gear for driving the lifting spindle is found, so that the seated person can be moved up and down from the rear end of the chair plate with the backrest can.
In den Zeichnungen ist die Erfindung dargestellt.The invention is illustrated in the drawings.
Fig.1 zeigt einen Schnitt durch die 3 Telescoprohre und der Betätigung der Gewindespindel'außerdem die Anordnung der Aufsitzfederung und der Befestigung der Stuhlplatte auf dem Querbalken des mittleren Telescoprohres.Fig.1 shows a section through the 3 telescopic tubes and the actuation the threaded spindle 'also the arrangement of the ride-on suspension and the fastening the chair plate on the crossbar of the central telescopic tube.
Fig.2 zeigt den Kegelradantrieb für die Gewindetragspindel und dessen Betätigung durch Welle und ebel.Fig.2 shows the bevel gear drive for the threaded spindle and its Actuation by shaft and lever.
Fig.3 zeigt wie Fig.1 die Betätigung der Gewindespindel und die Anordnung der Schwenkbewegung der Stuhlplatte.FIG. 3 shows, like FIG. 1, the actuation of the threaded spindle and the arrangement the swivel movement of the chair plate.
Fig.4 zeigt die Anordnung der Betätigungen für die Hub-und Schwenkbewegung der Stuhlplatte.4 shows the arrangement of the actuators for the lifting and pivoting movement the chair plate.
Die Stuhlplatte 7 des Drehstuhls ist entweder auf dem Querbalken 2 befestigt oder auf dem Querbalken 2 vorne drehbar und hinten durch die Hubepindel 17 und deren Antrieb 16/20 und den PUhrungsrohren 18 und 19 in der Höhe verstellbar.The chair plate 7 of the swivel chair is either on the crossbar 2 attached or rotatable on the crossbar 2 at the front and at the rear by the lifting spindle 17 and their drive 16/20 and the PUhrungsrohren 18 and 19 adjustable in height.
Die Verstellung wird vom Sitzenden aus durch das leicht bewegliche Handrad 20 vorgenommen.The seat can be adjusted by the easily movable Handwheel 20 made.
Außerdem wird die Höhenveretellung des Querbalkens 2,bzv.der Stuhlplatte 7 durch die Kurbel 21 von den 8itsenden aus vorgenommen.In addition, the height adjustment of the crossbar 2 or the chair plate 7 made by the crank 21 from the 8itsenden.
Mittels der Kurbel 21 wird die Welle 22 gedreht und über das Kegelradgetriebe 3 die Spindel 4 in der Butter 5 gedreht und dadurch die Sitzplatte 7 in der Höhe verstellt.The shaft 22 is rotated by means of the crank 21 and via the bevel gear 3 the spindle 4 rotated in the butter 5 and thereby the seat plate 7 in height adjusted.
Zur Führung der Höhenverstellung sind 3 Telescoprohre 8,1,6 notwendig,wobei die Aufsitzfeder 11 zwischen dem inneren Telescoprohr 6 und dem äußeren Telescoprohr 8 angeordnet ist.3 telescopic tubes 8,1,6 are used to guide the height adjustment necessary, whereby the ride-on spring 11 between the inner telescopic tube 6 and the outer telescopic tube 8 is arranged.
Das äußere Telescoprohr 8 verhindert mittels Schraube 10 und einem Ring 23 das Verdrehen der Telescoprohre 8 und 6.The outer telescope tube 8 prevents by means of screw 10 and a Ring 23 the twisting of the telescopic tubes 8 and 6.
