Description

Die Erfindung betrifft einen Schuldrehstuhl; sie besteht darin, daß zwischen Fuß und Sitz des Stuhles ein Doppelkugellager angeordnet ist, dessen unterer Kugelring zwischen einer unteren und einer oberen Lagerscheibe und dessen oberer Kugelring mit kleinerem Durchmesser zwischen der oberen Lagerscheibe und dem Flansch eines das Lager zusammenhaltenden Mittelbolzens läuft.The invention relates to a school swivel chair; it consists in that a double ball bearing is arranged between the foot and seat of the chair, the lower Ball ring between a lower and an upper bearing disk and its upper one Ball ring with a smaller diameter between the upper bearing washer and the flange a central bolt holding the bearing together runs.

Auf diese Weise erhält man eine gute Stabilität und Haltbarkeit, denn bei einseitiger Belastung des Sitzes wird der Druck auf die eine Hälfte des unteren Kugellagers durch die gegenüberliegende Hälfte des oberen Kugellagers ausgeglichen. Der Stuhl ist dadurch großen Beanspruchungen gewachsen. Dazu kommt noch die leichte Drehbarkeit des Sitzes.In this way you get a good stability and durability, because with one-sided loading of the seat, the pressure is on one half of the lower one Ball bearing balanced by the opposite half of the upper ball bearing. As a result, the chair is able to withstand great stress. Then there is the easy one Rotability of the seat.

Die Abbildungen zeigen ein Ausführungsbeispiel der Erfindung: Abb. i ist eine Ansicht und Abb. 2 ein Schnitt durch das Kugellager.The figures show an embodiment of the invention: Fig. i is a view and Fig. 2 is a section through the ball bearing.

Der Stuhl i ist gebildet aus den Beinen :2 und dem Sitz 3 nebst Rückenlehne 4. Die Beine 2 sind in einem Klotz i i, der aus vier Seitenhölzern besteht, mittels Schwalbenschwanz eingelassen und durch Holzdübel gesichert.The chair i is made up of the legs: 2 and the seat 3 together with the backrest 4. The legs 2 are in a block i i, which consists of four side timbers, means Dovetail embedded and secured with wooden dowels.

Auf dem Klotz i i ruht das Doppelkugellager 5. Dieses besteht aus einer unteren Lagerscheibe 6 und einer oberen Lagerscheibe 611, zwischen denen der untere Kugelring 7 läuft, sowie einem oberen Kugelring 8 mit kleinerem Durchmesser, der zwischen der oberen Lagerscheibe 6a und dem als Flansch ausgebildeten oberen Teil 9 des Mittelbolzens 66 läuft, der das Lager 5 zusammenhält.The double ball bearing 5 rests on the block i i. This consists of a lower bearing disk 6 and an upper bearing disk 611, between which the lower ball ring 7 runs, as well as an upper ball ring 8 with a smaller diameter, that between the upper bearing disk 6a and the upper one formed as a flange Part 9 of the central bolt 66 runs, which holds the bearing 5 together.

Die untere Lagerscheibe 6 wird mit dem oberen Teil der Füße 2 durch Schrauben io, die obere Lagerscheibe 6a mit dem Sitz 3 verbunden.The lower bearing washer 6 is with the upper part of the feet 2 through Screws io, the upper bearing washer 6a connected to the seat 3.
