Description

Gegenstand der Erfindung ist ein verstellbarer Stuhl, dessen Sitz von einem mit Kerben versehenen Schaft getragen ist, in welche ein Sperrglied eingreift, das an einer vom Gestell getragenen Führungshülse für den Schaft gelagert ist. Gemäß der Erfindung ist die Führungshülse in einem am Gestell festen Führungsring drehbar gelagert und das Sperrglied als durch Fußdruck bedienbarer Hebel ausgebildet, ίο Der Stuhl hat sonach neben den bekannten Vorteilen der Verstellung der Sitzhöhe auch noch die Vorteile eines Drehstuhles. Dadurch, daß das Sperrglied als durch Fußdruck zu bedienender Hebel ausgebildet ist, wird eine sehr bequeme und rasche Verstellung des Stuhles ermöglicht, indem beide Hände zum Heben oder Senken des Sitzes frei sind.The invention relates to an adjustable chair, the seat of which is one with notches provided shaft is carried, in which a locking member engages on one of the frame worn guide sleeve is mounted for the shaft. According to the invention, the guide sleeve rotatably mounted in a fixed guide ring on the frame and the locking member as designed lever operated by foot pressure, ίο the chair has besides the well-known advantages the adjustment of the seat height also has the advantages of a swivel chair. As a result of that the locking member is designed as a lever to be operated by foot pressure, becomes a very convenient one and enables the chair to be adjusted quickly, leaving both hands free to raise or lower the seat.

Die drehbare Anordnung der Führungshülse, an welcher der Sperrhebel befestigt ist, bietet den Vorteil, daß dieser Sperrhebel durch Drehung des Sitzes schnell und leicht aufgefunden und in die zum Verstellen erforderliche Lage gebracht werden kann.The rotatable arrangement of the guide sleeve to which the locking lever is attached offers the advantage that this locking lever can be found quickly and easily by rotating the seat and can be brought into the position required for adjustment.

In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes darge- -' stellt, und zwar zeigtIn the drawing, two exemplary embodiments of the subject matter of the invention are shown. - 'represents, namely shows

Abb. 6 den Sitzschaft in einem Querschnitt. Das Stuhlgestell besteht aus den Stuhlbeinen 0, deren obere Enden mit dem oberen Führungsring 2 verschraubt sind. Unten bildet der untere Führungsring 3 die Verbindung der Stuhlbeine miteinander. In dem Führungsring 3 lagert die Hülse 4, die oben mit dem Tragring 5 versehen ist. Unten sind an der Hülse die Lappen 6 befestigt, in denen der Bolzen 7 wagerecht gelagert ist. Auf dem Bolzen lagert drehbar der Sperrhebel 8, der mit seiner Sperrnase 9 in eine der Kerben 11 des Sitzschaftes 10 eingreift.Fig. 6 the seat shaft in a cross section. The chair frame consists of the chair legs 0, the upper ends of which are screwed to the upper guide ring 2. At the bottom, the lower guide ring 3 forms the connection between the chair legs. The sleeve 4, which is provided with the support ring 5 at the top, is supported in the guide ring 3. The tabs 6, in which the bolt 7 is mounted horizontally, are attached to the sleeve at the bottom. The locking lever 8 is rotatably supported on the bolt and engages with its locking lug 9 in one of the notches 11 of the seat shaft 10.

Hierbei durchgreift die Nase die Durchgangsöffnung 12 der Hülse 4. Auf dem Bolzen 7 ist die Feder 13 gelagert, deren hakenförmig gebogene Enden 14 in die Aussparung 15 der Hülse 4 eingreifen, so daß infolge der Federwindungen der Federschaft 13 gegen den Hebel 8 drückt und seine Nase 9 in der Sperrlage festhält. Damit die Kerben 11 genau vor der Sperrnase 9 eingestellt bleiben und der Sitzschaft 10 in der Hülse 4 sich nicht drehen kann, ist der Schaft mit einer Nut 17 versehen, in die eine in der Hülse 4 sitzende Schraube 16 eingreift. Da die Hülse mit ihrem Tragring auf dem unteren Führungsring nur lose aufliegt, kann sie sich beliebig drehen, so daß der Schaft und der Sitz sich mitdrehen und der Stuhl dadurch als Drehstuhl dienen kann. Der Tragring könnte jedoch gegebenenfalls an dem Führungsring festgeschraubt werden, falls der Sitz nicht drehbar sein soll. Die Verbindung zwischen Tragring und Führungsring kann vorübergehend, z. B. mittels Steckstiftes, hergestellt werden.Here, the nose extends through the through opening 12 of the sleeve 4. On the bolt 7 is the spring 13 is mounted, the hook-shaped ends 14 of which into the recess 15 of the Engage sleeve 4 so that, as a result of the spring windings, the spring shaft 13 against the lever 8 presses and his nose 9 holds in the blocked position. So that the notches 11 are exactly in front of the locking nose 9 remain set and the seat shaft 10 cannot rotate in the sleeve 4 is the Shank provided with a groove 17 into which a screw 16 seated in sleeve 4 engages. There the sleeve with its support ring only rests loosely on the lower guide ring, it can move Rotate at will, so that the shaft and the seat rotate with it and the chair becomes a swivel chair can serve. However, the support ring could optionally be screwed to the guide ring if the seat should not be rotatable. The connection between the support ring and guide ring can temporarily, e.g. B. by means of a pin.

Wie Abb. 2 zeigt, kann die Hülse 18 nach oben hin über den Führungsring 3 hinaus verlängert sein, so daß der Tragring 19 der Hülse nicht auf dem Führungsring 3 aufliegt. Dann kann man zwischen dem Tragring 19 und dem Führungsring 3 auf den Schaft 10 eine Feder 20 aufstecken, so daß der Tragring 19 auf der Feder ruht und die Hülse 18 mitsamt dem Schaft 10 und dem Stuhlsitz nachgiebig gelagert ist. Damit beim Drehen der Hülse 18 die Feder 20 nicht auf dem Führungsring 3 schleift und das Drehen erschwert, ist zwischen die Feder 20 und den Führungsring 3 ein Auflagering 21 lose eingelegt. As FIG. 2 shows, the sleeve 18 can be extended upward beyond the guide ring 3 so that the support ring 19 of the sleeve does not rest on the guide ring 3. then a spring 20 can be placed on the shaft 10 between the support ring 19 and the guide ring 3 Attach so that the support ring 19 rests on the spring and the sleeve 18 together with the shaft 10 and the chair seat is resiliently supported. So that when the sleeve 18 is rotated, the spring 20 does not drag on the guide ring 3 and makes turning difficult, is between the spring 20 and the guide ring 3 a support ring 21 is loosely inserted.
