Description
<B>Stuhl mit federnd</B> neigbarer <B>Rückenlehne.</B> Die Erfindung betrifft einen Stuhl mit federnd neigbarer Rückenlehne.
Bei den bekannten Stühlen dieser Art ist entweder die Rückenlehne selbst mittels einer federnden Stütze gehalten, oder es sind Fe dern vorgesehen, die die am Sitz oder am Gestell des Stuhls schwenkbar angeordnete Rückenlehne federnd abstützen. In beiden Fällen ist für die Feder ein Widerlager am Sitz oder am Gestell des Stuhls notwendig. Diese Konstruktionen benötigen für die Ab stützung der Lehne und der Feder verhält nismässig viele Einzelteile, die die Herstel-\ Jung erschweren und den Preis des Stuhls erhöhen.
Es sind auch schon einfachere Lösungen bekanntgeworden, bei denen zum Beispiel die Stütze der Rückenlehne ganz aus Federstahl bestand. Dies hat jedoch den Nachteil, dass die Befestigung der Rückenlehne schwierig ist, da sich Federstahl nicht so leicht spanlos verformen und verarbeiten lässt wie die übli- ehen Rückenlehnenstützen. Auch wird der Preis durch die Verwendung einer ganz aus Federstahl bestehenden Rückenlehnenstütze nicht unwesentlich erhöht.
Diese Nachteile sind bei dem Stuhl gemäss der Erfindung vermieden. Bei diesem bildet die Rüekenlehnenfeder einen Teil der Rücken lehnenstütze. Die Feder selbst kann eine Blatt feder oder eine Schraubenfeder sein. In der Zeichnung ist als Ausführungsbei spiel der Erfindung ein Drehstuhl schema tisch dargestellt Fig.1 zeigt eine Seiten- und Fig. 2 eine Vorderansicht.
Der Sitz 1 ist mittels einer zwischen zwei Scheiben 2 und 3 eingespannten Platte 4 von der Tragsäule 5 getragen. Um die Säule 5 greift eine Drahtfeder 6 mit einem , Bügel, der durch eine Öse 7 an der Scheibe 3 hindurchgeführt ist, aber ebenfalls zwi schen zwei Haltescheiben festgeklemmt sein könnte. Um eine weiche Federung zu erzie len, ist der Federdraht auf beiden Seiten des , Bügels zu je einer - es können auch mehrere sein - schraubenartigen Schlaufe 8 gebogen. Die beiden Enden des Federdrahtes sind in die beiden Mündungen eines Rohrbügels 9 gesteckt, welcher den Halter der Rückenlehne trägt. Zur Begrenzung des Ausschlages der Rückenlehne ist das Rohr durch einen Bügel. 10 geführt, der an einer mit dem Sitz verbun denen Leiste angebracht ist. Durch die Schlau fen 8 der.
Feder 6 ist oberhalb der Platte 4 ein Stab 11 gesteckt, auf dem die Schlaufen 8 ruhen. Die Schenkel des Rohrbügels 9 weisen oben Kerben auf, in denen die Rückenlehne mit einer gebogenen Schiene mittels einer Schraube in der Höhe verstellbar befestigt. ist.
<B> Chair with resilient </B> inclinable <B> backrest. </B> The invention relates to a chair with resiliently inclinable backrest.
In the known chairs of this type, either the backrest itself is held by means of a resilient support, or Fe countries are provided, which resiliently support the pivotable backrest on the seat or on the frame of the chair. In both cases, an abutment on the seat or on the frame of the chair is necessary for the spring. These constructions require a large number of individual parts to support the backrest and the spring, which make it difficult to manufacture \ Jung and increase the price of the chair.
Simpler solutions have also become known in which, for example, the support of the backrest consisted entirely of spring steel. However, this has the disadvantage that the fastening of the backrest is difficult, since spring steel cannot be deformed and processed without cutting as easily as the usual backrest supports. The price is also not insignificantly increased by using a backrest support made entirely of spring steel.
These disadvantages are avoided in the chair according to the invention. In this case, the backrest spring forms part of the backrest support. The spring itself can be a leaf spring or a coil spring. In the drawing, a swivel chair is shown schematically as an embodiment of the invention, FIG. 1 shows a side view and FIG. 2 shows a front view.
The seat 1 is supported by the support column 5 by means of a plate 4 clamped between two panes 2 and 3. To the column 5 engages a wire spring 6 with a, bracket, which is passed through an eyelet 7 on the disc 3, but could also be clamped between tween two retaining washers. In order to obtain a soft suspension, the spring wire is bent on both sides of the bracket to one each - there can also be several - screw-like loop 8. The two ends of the spring wire are inserted into the two mouths of a tubular bracket 9 which carries the holder of the backrest. To limit the deflection of the backrest, the tube is through a bracket. 10 out, which is attached to a verbun with the seat which bar. Through the loops 8 of the.
Spring 6, a rod 11 is inserted above the plate 4 on which the loops 8 rest. The legs of the tubular bracket 9 have notches at the top, in which the backrest is fastened adjustable in height with a curved rail by means of a screw. is.
