Rail arrangement for reversible school desks.
Zusatz zum Patente 160228 vom 29. Januar 1903.Addendum to patent 160228 of January 29, 1903.
Patentiert im Deutschen Reiche vom 27. Mai 1904 ab. Längste Dauer: 28. Januar 1918.Patented in the German Empire on May 27, 1904. Longest duration: January 28, 1918.
Bei der durch Patent 160228 geschützten Schienenanordnung für umlegbare Schulbänke muß der wagerechte Schenkel jeder Schiene der Beanspruchung auf seitliche Durchbiegung entsprechend breit bemessen werden. Auch bei ganz zusammengeschobenen Schienen muß an der Stoßstelle zweier Schienen die dritte Schiene allein die erforderliche Steifigkeit aufweisen. Hieraus ergibt sich eine sehr große Breite der doppelt aneinander liegenden Schienen.With the rail arrangement for convertible school desks protected by patent 160228 the horizontal leg of each rail must be exposed to lateral deflection be dimensioned accordingly wide. Even with the rails pushed together completely At the point where two rails meet, the third rail alone has the required rigidity exhibit. This results in a very large width of the double adjacent Rails.
Die gegenwärtige, auf der beiliegenden Zeichnung dargestellte Erfindung hat nun den Zweck, so weit wie möglich eine Verminderung der bedeckten Fußbodenfläche zu erzielen, um deren Reinhaltung zu erleichtern.The present invention shown in the accompanying drawings now has the Purpose of reducing the covered floor area as much as possible, to make it easier to keep them clean.
Erreicht wird dieser Zweck dadurch, daß über die Stoßstellen χ (Fig. 1 bis 4) von oben ein U-förmiges Versteifungsstück g geschoben wird, das die durch den Schienenstoß verminderte Steifigkeit voll ersetzt. Dieses Versteifungsstück kann aufgeklemmt oder mit einer der Schienen fest verbunden werden. Seine Länge muß derart bemessen sein, daß das Auseinanderziehen der Schienen in dem gewünschten Maße möglich bleibt.This purpose is achieved in that a U-shaped stiffening piece g is pushed over the joints χ (Fig. 1 to 4) from above, which fully replaces the stiffness reduced by the rail joint. This stiffening piece can be clamped on or firmly connected to one of the rails. Its length must be such that the rails can still be pulled apart to the desired extent.
Aus den Fig. 5 und 6 ist zu ersehen, daß die Versteifungsstücke g auch zwischen je zwei Bänke gelegt werden können.From Figs. 5 and 6 it can be seen that the stiffening pieces g can also be placed between two banks.
