Description
Einrichtung zum Befestigen der Stuhlfüsse eines Drehstuhls mit dessen Spindellager Vorliegende Erfindung betrifft eine Ein richtung zum Befestigen der Stuhlfüsse eines Drehstuhls mit dessen Spindellager.
Bisher wurden die (Stuhlfüsse an mit dem Spindellager verbundenen Laschen ange schraubt. Diese Laschen sind bei vierfüssigen Stühlen kreuzförmig und benötigen, wenn sie aus Blech ausgestanzt sind, viel Material, da viel Abfall entsteht. .Sind diese Laschen aus Flacheisen und an dem Spindellager festge schweisst, dann entsteht teure Schweissarbeit.
Vorliegende Erfindung bezweckt, eine bil ligere Verbindung der Stuhlfüsse mit dem Spindellager zu schaffen. Die Erfindung be steht darin, dass das Spindellager der Zahl der zu befestigenden Füsse entsprechend minde stens je zwei übereinander angeordnete ra dial zur Spind'ellagerachse stehende Zapfen aufweist, über die das obere Ende je eines Stuhlfusses mit in,
diesem vorgebohrten Lö chern greift und mittels eines die beiden Zapfen und den Stuhlfuss durchquerenden Stiftes am Spindellag,er -befestigt ist.
In der beiliegenden Zeichnung ist eine beispielsweise Ausführungsform des Erfin dungsgegenstandes veranschaulicht. Es zeigt: Fig. 1 einen Drehstuhl mit vier Stuhl füssen, Fig. 2 das Spindellager desselben mit einem an diesem angeordneten .Stuhlfuss, Fig.3 einen Schnitt nach Linie I-I in Fig. 2.
Das Spindellager 1 ist zweckmässig aus Temperguss hergestellt und! weist Zapfen 2 auf, die senkrecht übereinander angeordnet sind und radial zur Spindellagerachse stehen. Entsprechend dem Anzahl Füsse 3 des \Stuhls sind im Umfang je zwei Zapfen Übereinan- der angeordnet. Das vorliegendle Ausführungs- beispiel ist beispielsweise mit vier Füssen versehen.
Die Füsse 3, beispielsweise aus Holz, sind an ihrem obern Ende mit Löchern 3a versehen, welche über die Bolzen 2 greifen. Die Befestigung des iStuhlfusses mit dem Spin- dellager erfolgt durch den Stift 4, der so wohl das obere Ende des Fusses als auch die Zapfen 2 durchquert.
Mittels Bohrlehren wer den die Löcher 3,a sowie das Stiftenloch für den Stift 4 in den .Fuss .3 sowie in die Zapfen 2 eingebohrt, und zwar derart, d'ass im Fuss 3 der Abstand zum Stiftenloch von der Auf lagefläche 3b desselben etwas grösser ist als der Abstand a der Stiftlöcher in den Bolzen 2 von der Wand ,
des Spindellagers. Dadurch wird beim Einschlagen des Stiftes 4 der Fuss fest gegen dIas Spindellager angezogen, also an die Wand des Spindellagers angepresst. Diese Befestigung ist viel dauerhafter als die bisherige Befestigung mittels Schrauben und wesentlich billiger als diese herzustellen.
Ausserdem ist der iStuhl in bezug auf seine Belastung wesentlich widerstandsfähiger. Ein weiterer Vorteil besteht darin, dass die Schmal seiten der Füsse, mit .Ausnahme der Anstoss fläche, eine durchgehend gleich gewölbte Form haben können, .die mit einem Fräser in einem Arbeitsgang herstellbar ist.
Device for attaching the chair feet of a swivel chair with its spindle bearing The present invention relates to a device for attaching the chair feet of a swivel chair with its spindle bearing.
Up to now, the (chair feet were screwed onto brackets connected to the spindle bearing. These brackets are cross-shaped on four-legged chairs and, if they are punched out of sheet metal, require a lot of material because a lot of waste is generated. Are these brackets made of flat iron and fixed to the spindle bearing welds, then there is expensive welding work.
The present invention aims to create a bil ligere connection of the chair feet with the spindle bearing. The invention consists in that the spindle bearing has at least two pins arranged one above the other radial to the spindle bearing axis, corresponding to the number of feet to be fastened, via which the upper end of each chair foot with in,
This pre-drilled holes engages and by means of a pin that traverses the two pins and the chair base on the spindle support, it is fastened.
In the accompanying drawing, an example embodiment of the subject invention is illustrated. It shows: FIG. 1 a swivel chair with four chair feet, FIG. 2 the spindle bearing of the same with a chair foot arranged thereon, FIG. 3 a section along line I-I in FIG.
The spindle bearing 1 is expediently made of malleable cast iron and! has pins 2, which are arranged vertically one above the other and are radial to the spindle bearing axis. According to the number of feet 3 of the chair, two pegs are arranged one above the other in the circumference. The present exemplary embodiment is provided with four feet, for example.
The feet 3, for example made of wood, are provided at their upper end with holes 3 a, which engage over the bolts 2. The attachment of the chair foot to the spindle bearing is carried out by the pin 4, which crosses both the upper end of the foot and the pin 2.
Using drilling jigs who the holes 3, a and the pin hole for the pin 4 in the .Fuss .3 and in the pin 2 drilled, in such a way, d'ass in the foot 3 the distance to the pin hole from the support surface 3b of the same something is greater than the distance a of the pin holes in the bolts 2 from the wall,
of the spindle bearing. As a result, when the pin 4 is hammered in, the foot is tightened against the spindle bearing, that is, it is pressed against the wall of the spindle bearing. This fastening is much more permanent than the previous fastening by means of screws and much cheaper to manufacture than this.
In addition, the iStuhl is much more resistant to stress. Another advantage is that the narrow sides of the feet, with the exception of the abutment surface, can have a consistently curved shape that can be produced with a milling cutter in one operation.
