Yorrichtung zürn vffnea der federbelastet en Sperre eines neigbaren Trägers der Rückenstütze eines Bürostunles.Yorrichtung zürn vffnea the spring-loaded lock of an inclinable carrier of the backrest of an office chair.

Die Erfindung betrifft eine Torrichtung zum öffnen der federbelasteten Sperre eines neigbaren Trägers der Rückenstütze eines Bürostuhles, wobei der Halter des Trägers mittels eines Gelenkbolzens am Kopf der Sitzplatte angelenkt ist. Erfindungsgemäß besteht die Verrichtung aus einem am Halter angelenkten Ankerbolzen, aus kippbaren Sperrscheiben, aus diesen belastende vorgespannten druckfedern und aus einem Exzenter mit Handhebel, so daS die Sperx-seheiben asa Exzenter anliegen.The invention relates to a door direction for opening the Spring-loaded lock of a tiltable support of the backrest of an office chair, the holder of the support is articulated by means of a hinge pin on the head of the seat plate. According to the invention, the performance consists of an anchor bolt articulated to the holder, made of tiltable locking disks, from these stressful pre-tensioned compression springs and from an eccentric with a hand lever, so that the sperx discs are in contact with the eccentric.

in weiterer Ausgestaltung dieser Hauptsache des Erfindungsgegenstandes durchdringt der Ankerbolzen kreisförmigen Profiles die Sperrscheiben, wobei die Sperrscheiben rechteckig sein können und dazuhin vorzugsweise der Halter von einer auf dem 6-elenkbolzen geführten Schenkelfeder belastet ist» so daß das Ende des einen Schenkels dieser Schenkelfeder in den Spalt zwischen dem Kasten der führung des Trägers und der Bolzenhülse des Aiikerbolzens hineintaucht·In a further embodiment of this main subject of the invention, the anchor bolt penetrates circular Profiles the locking washers, the locking washers being rectangular can be and in addition preferably the holder of a leg spring guided on the 6-pivot pin is loaded »so that the end of one leg of this leg spring into the gap between the box of the guidance of the carrier and the bolt sleeve of the aiikerbolzens immersed in

Bekanntlich, sind wahllose Vorrichtungen der Gattung des Erfindungsgegenstandes im Handel gewesen und dann wieder verschwunden, hauptsächlich deshalb weil sie unzuverlässig in der funktion waren» Demgegenüber ist das Erfundene sicher, billig und leicht verständlich, wie dies auch die Pigur verdeutlicht, welche ein Ausführungsbeispiel wiedergibt. Dargestellt ist die Mechanik im Längsmittelschnitt und zwar bei geöffneter Klemme. Das Beingestell und die Sitsplatte des Stuhl.es sind nicht abgebildet*As is known, random devices are of the genus of the subject matter of the invention have been on the market and then disappeared again, mainly because they were unreliable in their function what is invented is safe, cheap and easy to understand, as Pigur makes clear, which one Embodiment reproduces. The mechanism is shown in the longitudinal center section, namely when it is open Clamp. The leg frame and the seat plate of the chair are not shown *

Die Hauptteile der Vorrichtung sind der Kopf 1 als Konsole, der Halter 2f welcher ™ den Gelenkbolzen 18 nach dem lösen der Klemme entgegen der Schenkelfeder 11, 12, 13 wippbar ist. Tier Kasten- 20 des Halters 2 lagert den federbelasteten Bolzen 14, der mittels eines Knebels (Gabel 15) in bekannter Weise iai der Art verschiebbar ist, daß der Sräger 16 der nicht dargestellten Sückenstütze in Sichtung E oder 3? verschiebbar ist· Die Lochreihe im Eräger 16 für den Bolzen 14 ist nicht veranschaulicht·The main parts of the device are the head 1 as a console, the holder 2 f which ™ the hinge pin 18 after loosening the clamp against the leg spring 11, 12, 13 can be rocked. Tier box 20 of the holder 2 supports the spring-loaded bolt 14, which is generally displaceable by means of a toggle (fork 15) in a known manner in such a way that the carrier 16 of the saddle support, not shown, is in sight E or 3? The row of holes in the bracket 16 for the bolt 14 is not illustrated

Wesentlich ist die Klemme 3* 4» 5* β, ?, 8» Sie ist nach dem Bild geöffnet, so daß der Jkakerbolsen 4 reibungsarm. leiehi; is den Sperrseheiben hin— und suruek·*The terminal 3 * 4 »5 * β,?, 8» is essential opened according to the picture so that the Jkakerbolsen 4 low friction. leiehi; is the locking disks to - and suruek *

rutschen kann (Richtung A oder B)0 Wird der Handhebel 8 freigegeben, stellt eine gezeichnete aber nicht bezifferte jf-eder den Handhebel 8 nach unten (Pfeil H) und damit den Exzenter 7 so flach, daß die Druckfedern 6 die Sperrscheiben stärker verkanten können· Dies so stark, daß. sich Sperrscheibenkanten mit dem Ankerbolzen 4· Terzahnen können· Dadurch wird eine harte, leicht formschlüssige, rastende Klemmsperrung erreicht·can slip (direction A or B) 0 If the hand lever 8 is released, a drawn but not numbered jf-eder moves the hand lever 8 downwards (arrow H) and thus the eccentric 7 so flat that the compression springs 6 can tilt the locking disks more strongly · This so strong that. The locking disc edges can be joined with the anchor bolt 4 third teeth This results in a hard, slightly form-fitting, locking clamp lock

Nicht befürchtet braucht werden, daß der Verschleiß groß ist· Die feinen Zähne werden nur selten überfahren. Und dies geschieht ohne hohen spezifischen DrückeeThere is no need to fear that the wear and tear is great · The fine teeth are seldom run over. And this happens without high specific pressures

Die Anschläge 9 und 10 sind Bedienungshilfen. Der Soläsn 18 enthalt die Kippaehse der Rückenstütze*The stops 9 and 10 are operating aids. The Soläsn 18 contains the Kippaehse of the back support *

In der Sperrstellung sind es demnach vier Kanten der vier Sperrscheiloen, die mit dem Ankerbolzen die Peststellvorrichinmg für die Eückenstütse bilden·In the locked position there are therefore four edges of the four locking screws that secure the Peststellvorrichinmg with the anchor bolt for the back support
