Description

Stahlrohrstühle in den verschiedensten Ausführungen, hauptsächlich für Schulzwecke, sind seit langem bekannt. Die normale vierbeinige Ausführung hat den Nachteil, daß der Stuhl beim Verrücken sehr viel Lärm macht. Es wurden deshalb Bügelstühle entwickelt, bei welchen das Stahlrohr in Form eines U-Bügels auf dem Boden schleift: Diese Stühle werden von den Lehrkräften stets vorgezogen, weil sie beim Aufstehen des Schülers geräuschloser zurückgleiten. Diese Stühle haben jedoch den Nachteil, daß sich das am Boden schleifende Rohr über kurz oder lang abnützt und der Stuhl auf dieseWeise unbrauchbarwird. Vereinzelt wurden deshalb diese Bügel mit aufgelöteten Verstärkungen in Form von Rohrhälften versehen, um das Durchschleifen des Grundrohres zu verhindern. Diese Art Muffen haben mit dem Fußboden jedoch auch nur wieder Punktberührung, weil dieselben unten rund bzw. dem Sesselrohr angepaßt sind. Der Nachteil der bisherigen Bügelstühle ist auch der, daß sie leicht zum Kippen neigen, da die Rohrbögen vorn und hinten die Auflage des Stuhles am Boden verkürzen.Tubular steel chairs in various designs, mainly for school purposes, have long been known. The normal four-legged version has the disadvantage that the chair makes a lot of noise when it is moved. It was because of that Ironing chairs developed in which the steel tube in the form of a U-bracket on the Floor grinds: These chairs are always preferred by teachers because they slide back more noiselessly when the student gets up. However, these chairs have the disadvantage that the pipe rubbing on the ground wears out sooner or later and the chair becomes unusable in this way. This is why these brackets were sporadic provided with soldered-on reinforcements in the form of pipe halves to allow looping through to prevent the base pipe. However, this type of sleeves also have with the floor only point contact again, because they are round below or adapted to the chair tube are. The disadvantage of previous ironing chairs is that they are easy to tilt incline, as the pipe bends at the front and back shorten the contact between the chair and the floor.

Zur Behebung dieser Nachteile wurde der gezeigte Stuhl entwickelt, bei welchem vorn und hinten ie eine Gleitkufe aus Temper,-uß mit den Ständerrohren verschweißt ist. Dieses Kufenstück ist unten mit einer Fläche versehen, damit der Stuhl besser gleitet. Um der Abnützung vorzubeugen, kann das Kufenstück mehrere Millimeter stark sein.To remedy these disadvantages, the chair shown was developed, in which front and rear ie a skid made of tempered cast iron with the upright tubes is welded. This piece of runner is provided with a surface at the bottom so that the Chair slides better. To prevent wear and tear, the runner piece can have several Be millimeters thick.

Der Stuhl hat durch die scharfen Ecken außerdem ein besseres Standvermögen, wodurch jedes Kippen nach vorn oder hinten verhindert wird. In der Abbildung ist die Ausführung eines derartigen Stuhles dargestellt. Die normalen Stuhlbeine a sowie die Quertraverse b sind in die Gleitkufen c gesteckt und mit diesen verschweißt. Die Gleitkufen stehen mit der unteren Fläche d einige Millimeter über die Rohrunterkante hinaus.The chair also has better stability due to the sharp corners, thereby preventing any tipping forwards or backwards. In the picture is the execution of such a chair shown. The normal chair legs a as well the crossbars b are inserted into the skids c and welded to them. The lower surface d of the skids is a few millimeters above the lower edge of the pipe out.
