Die Erfindung bezieht sich auf eine Höheneinstellvorrichtung für Kontor-, Musikstiihle, Tische und sonstige Möbei o. dgl., bei denen die Einstellung mittels einer in der Führungshülse gelagerten, in Rasten der Führungsstange eingreifenden Kugel erfolgt. Die Erfindung besteht darin, daß sich an dom Kanal in der Hülse, in dem die Kugel gegen die Führungsstange federnd g'-lagert ist, ein nach abwärts to gerichteter Hüfekanal anschließt, dergestalt, daß bei geringer Drehung des Stuhlsitzes oder sonstigen Gegenstandes die Kugel durch die Führungsspindel in den H.lfskanal geschoben wird, wodurch tue Feststellung der den Sitz ader sonstigen Gegenstand tragenden Führungsstange lewirkt wird. Zur Erleichterung des Gleitens sind die Rasten der Führungsstange durch eine runde Nut miteinandi r verbunden. Die Feder ist an dem gegen die Kugel pressenden Ende mit einer Gleitschutzkappe ausgerüstet. The invention relates to a height adjustment device For office chairs, music chairs, tables and other furniture or the like, where adjustment by means of a guide rod mounted in the guide sleeve in notches engaging ball takes place. The invention consists in that dom channel in the Sleeve in which the ball is resiliently G'-mounted against the guide rod, a downwards connected to directed hip canal in such a way, that with little rotation of the chair seat or other object, the ball is pushed through the guide spindle into the support channel is, whereby do determination of the seat vein other object-carrying guide rod is acted. To facilitate the The notches of the guide rod are connected to one another by a round groove. The spring is on the one pressing against the ball End equipped with an anti-slip cap.

Die den Sit/, oder sonstigen Gegenstand tragende Führungsstange α ist mit einer Reihe von aufgerundeten Rasten ö1 versehen, die durch eine runde Nut b miteinander verbunden sind. Der Flansch der Führungshülse Ii ist durchbohrt, so daß ein Kanal d zur Aufnahme der Kugel c gebildet ist. Der Kanal ist durch die Schraube c verschlossen; diese besitzt eine angedrehte Zapfenführung e1 zur Aufnahme der Feder /', die am inneren Ende die (Ueitscliutzkapsel g trägt. An dem Kanal d schließt sieh ein Hillskanal Ii mit dem sackförmigen, abwärts gerichteten Ende i (s. Abb. 7) an. The guide rod α carrying the seat / or other object is provided with a number of rounded notches ö 1 which are connected to one another by a round groove b. The flange of the guide sleeve Ii is drilled through, so that a channel d for receiving the ball c is formed. The channel is closed by screw c ; This has a turned pin guide e 1 for receiving the spring / ', which carries the Ueitscliutzkapsel g at the inner end. A Hill channel Ii connects to the channel d with the sack-shaped, downwardly directed end i (see Fig. 7).
Die Wirkungsweise der Einstellvorrichtung ist folgende: Solange die Kugel e sich im Kanal*/ befindet, kann die Führu-.gsstange α aufwärts und abwärts verstellt werden, wobei die Kugel unter Überwindung des Federdruckes und unter Vermittlung der Nut b von einer Rast in die andere gleitet. Zwecks Feststellung des Sitzes oder sonstigen Gegenstandes in der gewünschten Höhe ist eine kleine Drehung desselben um etwa 45° erforderlich. Hierdurch Avird die Kuge! durch die Rast, mit der sie gerade im Eingriff steht, in den Hilfskanal h geschoben und gleitet /.ufolge Belastung durch den Sitz oder sonstigen Gegenstandes mbst Führungsstange in den abwärts gerichteten Teil * des Hiifskanals. wodurch die Führungss'ange festgesetzt ist. In ähnlicher Weise erfolgt die Lösung, doch ist der Sitz oder sonstige Gegenstand dabei zunächst ein wenig anzuheben.The mode of operation of the adjustment device is as follows: As long as the ball e is in the channel * /, the guide rod α can be adjusted upwards and downwards, the ball moving from one detent to the other by overcoming the spring pressure and mediating the groove b slides. To fix the seat or other object at the desired height, a small turn of the same by about 45 ° is necessary. This avird the ball! pushed into the auxiliary channel h by the detent with which it is currently engaged and slides into the downwardly directed part * of the auxiliary channel as a result of the load caused by the seat or other object. whereby the guide length is fixed. The solution is carried out in a similar way, but the seat or other object must first be lifted a little.
