Abstract

Backrest support is designed as an arcuate cradle consisting of two horns (1, 2) and the transverse head (3) of the frame has arcuate segments (17) formed from toothed rods which interact with an unlocking device mounted on the frame of the seat plate (4). The seat plate and backrest can be inclined in stages forward and backwards when the lock bolt (20) is released. The seat plate is pref. designed so that it can be inclined about one of the axes of one of the pairs of rollers which form part of the cradle for the horns. A double-armed spring-biased lever (18, 19) can be provided which when swivelled in one direction causes the lock (20) to be pushed out of gaps in the toothed arcuate segments (17).

Description

Bürostuhl. Office chair.

Die Erfindung betrifft einen Bürostuhl mit gegenüber dei Gestell neigbarer Sitplatte und mit gegenüber der Sitzplatte neigbarer Rückenstütze, wobei die drei Teile Gestell (Tragsäule), Sitzplatte und Rückenstütze feststellbar sind. Gekennzeichnet ist das Brfundene daduroh, daß der Träger der Rückenstütze mit als kreisbogenförmige Wiege eine aus zwei Hörnern ist, daß das Querhaupt des Gestelles eines oder in mehrere Zahnstangenbogensigiente besitzt und daß der Rahmen der Sitzplatte eine mit den Zahnstangenbogensegmenten @usammenwirkende Entriegelvorrichtung aufweist, so daß die Sitzplatte sant Rückenstüt@e nach dem Lösen des Riegels in bekannter Weise stufenweise vor- bsw. rückwärts neigbar ist.The invention relates to an office chair with a frame that can be tilted with respect to the frame Seat plate and with a backrest that can be inclined in relation to the seat plate, the three Parts of the frame (support column), seat plate and backrest can be locked. Marked is the Brfundene daduroh that the carrier of the backrest with as a circular arc The cradle of one of two horns is that the crosshead of the frame is one or more Rack bow sign and that the frame of the seat plate has one with the Rack arch segments @ interacting unlocking device, so that the seat plate sant backrest @ e after loosening the bolt in a known manner in a step-by-step manner vor- bsw. can be tilted backwards.

Eine erfinderische Ausgestaltung dieser Idee ist dadurch gekennzeichnet, daß die Sitzplatte um eine der Achsen eines der Rollenpaare neigbar ist, deren Rollen Teile der Wiege flir die Hörner sind.An inventive embodiment of this idea is characterized in that that the seat plate can be tilted about one of the axes of one of the pairs of rollers, their rollers Parts of the cradle for the horns are.

Der Vorteil dieser Konstruktionen besteht darin, daß der Bürostuhl rasch umstellbar ist, ohne daß die sitzende Person nach dem Umstellen in die Angst verfällt, der Stuhl sei durch das Umstellen unsicher geworden.The advantage of these designs is that the office chair can be changed quickly without the seated person feeling afraid after the change forfeited, the chair had become unsafe as a result of the repositioning.

Die Zeichnung zeigt ein Ausführungsbeispiel schematisch, wobei es beim Darstellen darauf anka@, die erfindungswesentlichen Elemente deutlich wiedersugeben. Die Fig 1 offenbart einen Vertikal-Querschnitt, während die Fig 2 und 3 Vertikalquerschnitt@ um 90° gedrcht wiedergeben.The drawing shows an exemplary embodiment schematically, with it when representing it anka @ to clearly reproduce the elements essential to the invention. Fig. 1 reveals a vertical cross section, while Figs. 2 and 3 show a vertical cross section @ play back rotated by 90 °.

Die Rückenstütse und das Beingestell sind weggelassen.The back support and the leg frame are omitted.

Die Hauptteile sind die Rohre 1, 2 (Kreisbogenteile 1, Geradteile 2) als Wiege, das Gehäuse 3, die Rastensperre 4, 5 samt Hebel 6, die Kuppelplatte 7 (zwischen die Rohre eingeschweißt) und die Zentralsäule 8, welche die Sitsplatte 9 trägt.The main parts are pipes 1, 2 (circular arc parts 1, straight parts 2) as a cradle, the housing 3, the ratchet lock 4, 5 including lever 6, the coupling plate 7 (welded between the tubes) and the central column 8, which is the seat plate 9 wears.

Unschwer entnimmt man der Fig 1, daß sich in der Kuppelplatte 7 ein Schlitz 11 erstreckt. Ein Rand iet mit einer Zahnstange 5a versehen. In eine der Zahnlücken ist der Zahn 5 eingerastet, wenn die Rückenstütze recht eingestellt ist. Die die Handhabe 6 belastete Peder ist nicht dargestellt.It is easy to see from FIG. 1 that there is a 7 in the coupling plate Slot 11 extends. One edge is provided with a rack 5a. In one of the Tooth gaps, tooth 5 is locked when the back support is adjusted correctly. The peder loaded on the handle 6 is not shown.

Mithin sind die beiden Rohre 1, 2 mittels der gezahnten Kuppelplatte 7 (ein Zahnstangenbogen) verbunden, deren Zähne Teile der Rastensperre sind. Die Teile 1 der Rohre 1, 2 sind zwischen Paaren der an Gehäuse 3 gelagerten Rollen 16 gelagert, Der entgegen der Kugelplatte federbelastete Hebel 6 der Rastansperre ist einarmig. Die L-förmigen Rohre 1, 2 sind hornförmig und zum Teil kreisbogenförmig gekrümmt, z.B.Thus, the two tubes 1, 2 by means of the toothed coupling plate 7 (a rack arch), the teeth of which are part of the ratchet lock. the Parts 1 of the tubes 1, 2 are between pairs of the rollers 16 mounted on the housing 3 stored, the against the ball plate spring-loaded lever 6 is the locking device one-armed. The L-shaped tubes 1, 2 are horn-shaped and partly in the shape of a circular arc curved, e.g.

zwischen Winkeln von 30 bis 100°, beim Ausführung@beispiel extrem bei o@ 100°. Bei nermalen Bürestühlen genügen 30°.between angles of 30 to 100 °, with the @ example extreme at o @ 100 °. 30 ° is sufficient for neral brush chairs.

Die Rollen 16 werden von den Bolzen 12, 13, 14, 15 getragen.The rollers 16 are carried by the bolts 12, 13, 14, 15.

Die Fig 3 zeigt diejenige Zusammenstellung, auf die es nach der Erfindung ankommt. Die Entriegelvorrichtung für die Baugruppe Hörner 1, 2 mit Rückenstütze und Sitzplatte mit Rahmen 3 ist um die Achse des Bolsen 14 in Riohtung C oder D schwenkbar, wenn der Handhebel 18 des doppelarmigen, in Richtung G federbelasteten Hebels 18, 19 durch Druck E in Richtung P geschwenkt und dabei der in Richtung H aua Zahnlücken der Zahnstangenbogensegmenten 17 herausschiebbare Riegel 20 entsperrend verstellt wird. Geschieht dies, bewegt sich die Baugruppe 1. 2, 3, 9 in Richtung A oder B. Das Wiederfeststellen erfolgt nach dem Loslassen des Handhebels 18.Fig. 3 shows that compilation to which it is according to the invention arrives. The unlocking device for the assembly horns 1, 2 with back support and seat plate with frame 3 is around the axis of the bolt 14 in direction C or D. pivotable when the hand lever 18 of the double-armed, spring-loaded in the direction G Lever 18, 19 pivoted by pressure E in direction P and thereby in direction H also gaps in the toothed rack arch segments 17 unlocking latches 20 is adjusted. If this happens, the assembly 1. 2, 3, 9 moves in the direction A or B. Re-locking takes place after releasing the hand lever 18.

Die Zahnstangenbogensegmenten 17 sind mit der Säule @ fest verbunden.The rack arch segments 17 are firmly connected to the column @.
