Solingen-Ohligs, den 14· September 19&5 Stuhl, insbesondere BürodrehstuhlSolingen-Ohligs, September 14th, 19 & 5 Chair, especially office swivel chair
Die Heuerung betrifft einen Stuhl, insbesondere Bürodrehstuhl} dessen Rückenlehne mittels einer Doppelstabfeder am Sitzgestell befestigt ist.The Heuerung relates to a chair, in particular office swivel chair} whose backrest is attached to the seat frame by means of a double-bar spring.
Derartige Doppelstabfedern sind bei Stühlen bekannter jßauart ir.it ihren freien Enden an der Sitzplatte bzw. an deren Verankerung gehalten, wobei die zumeist bei Drehstühlen verschiebbar gehaltenen freien Enden aus Gründen der Stabilitäts der Verdrehsicharheit und einer klemmfreien Führung durch angeschweißte Verbindungsstoge, durch Bietung etc. oder aber durch unmittelbare Stoßverschweißung· miteinander verbunden sind. Die derart hergestellten Yerbind.ur.f3n der freien Enden der Doppelstabfeder beanspruchen verhältnismäßig viel Zeitaufwand und sind infolge der von der belasteten Rückenlehne ausgehenden Verdrehbeanspruchung auf die Dauer nicht geni .^end bruchfest. Hinzu kommendurch das Schweißen verursachte nachteilige Gefügeveränderungen der aus Federstahl bestehenden Doppelstabf. " :· „Such double bar springs are held in chairs of known jßauart ir.it their free ends on the seat plate or on its anchoring, the free ends, which are usually held displaceably in swivel chairs, for reasons of stability s the torsional security and a jam-free guidance by welded connecting rods, by bidding, etc. .or are connected to one another by direct butt welding. The Yerbind.ur.f3n the free ends of the double bar spring produced in this way require a relatively large amount of time and are not sufficiently break-proof in the long term due to the torsional stress emanating from the loaded backrest. In addition, there are disadvantageous changes in the structure of the double rod, which is made of spring steel, caused by welding. ": ·"
Um alledem abzuhelfen, sieht die Neuerung vor, die freien Enden der Doppelstabfeder durch eine Muffe miteinander zu verbinden. Auf diese Weise ist es möglich, die beiden freien Stabfederenden auf kaltem Wege durch einfaches Zusammenstecken montagevereinfachend und bruchsicher zu verbinden.To remedy all of this, the innovation provides for the free ends of the To connect the double bar spring with a sleeve. To this It is possible to assemble the two free rod spring ends in a cold way by simply plugging them together, making them easier to assemble and unbreakable connect to.
Die Neuerung ist an zwei in der Zeichnung veranschaulichten Ausführungsbsispielen in der nachfolgenden Beschreibung näher erläutert.The innovation is closer to two exemplary embodiments illustrated in the drawing in the following description explained.
In der Zeichnung zeigen:In the drawing show:
Fig. 1 die Gesamtansicht eines Bürodrehstuhls mit einer Fig. 1 is the overall view of an office swivel chair with a
zur KückenlehnenhaIterung dienenden Doppelstabfederdouble bar spring used to hold the backrest
Fig. 2 die ausschnittweise Darstellung neuerungsgemäß Fig. 2 shows the partial representation according to the innovation
verbundener freier Enden der Rückenlehnen-Doppelstabfeder in vergrößertem Maßstabconnected free ends of the backrest double bar spring on an enlarged scale
Fig. 3 der Darstellungsweise gemäß Fig. 2 entsprechend FIG. 3 corresponds to the representation according to FIG. 2
ein weiteres Ausführungsbeispiel einer Verbindung der Doppelstabfederenden.Another embodiment of a connection of the double bar spring ends.
Die Neuerung ist in der Zeichnung an einem Bürodrehstuhl an sich bekannter Bauart veranschaulicht. Dieser Stuhl besteht im wesentlichen aus einem mit Fahrrollen 1 bestückten Fußkranz 2 mit einer höhenverstellbaren Standsäule 3 und einer daran angebrachten Befestigungsplatte 4 für den Sitz 5 und einer Feder β zur Halterung einer in der Höhe verstellbaren Rückenlehne 1J. The innovation is illustrated in the drawing on an office swivel chair of a known type. This chair essentially consists of a base 2 equipped with castors 1 with a height-adjustable column 3 and a mounting plate 4 attached to it for the seat 5 and a spring β for holding a height-adjustable backrest 1 J.
Die Feder 6, welche in bekannter Weise aus zwei in gleichen Abständen nebeneinander parallel verlaufenden Stahlstäben besteht und einenendes eine ha&rnadelförmige, nicht näher veranschaulichte Krümmung 6a aufweist, läuft, wie aus der vergrößerten Teildarstellung "gemäß Fig. 2 ersichtlich, in freien Enden 6b und 6c aus. Diese Enden sind zangenartig gekröpft und solcherart durch eine'zylindrische Kuffθ 8 miteinander verbunden. Selbstverständlich ist die Neuerung auf dieses Ausführungsbeisprel nicht beschränkt; vielmehr können die freien Enden der Doppelstabfeder 6 beispielsweise auchlgeradlinig auslaufen und durch eine bogenförmige Muffe 80 in der aus Figur 3 ersichtlichen Weise miteinander verbunden sein.The spring 6, which in a known manner consists of two equally spaced steel rods running parallel to one another and at one end a hairpin-shaped, not illustrated curvature 6a has, runs, as shown in the enlarged partial representation "according to Fig. 2 can be seen in free ends 6b and 6c. These ends are Cranked like pliers and in such a way through a cylindrical Kuffθ 8 connected with each other. Of course, the innovation is not limited to this exemplary embodiment; rather, the free Ends of the double bar spring 6, for example, also taper off in a straight line and by an arcuate sleeve 80 in that shown in FIG Way to be connected.
Die Muffe und die Enden 6b und 6o können aufeinander gepreßt oder durch zusätzliche Klebung miteinander verbunden und in beiden Fällen zusätzlich noch lagegesichert verankert sein, zum Beispiel durch Meißel- bzw. Körnerschlag (9), Stiftsicherung oder dergleichen.The sleeve and the ends 6b and 6o can be pressed or pressed onto one another be connected to each other by additional adhesive and in both cases additionally anchored in a secured position, for example by Chisel or center punch (9), pin lock or the like.
