Bei dem Gebrauche des Rollschuhes nach dem Hauptpatent 608 229 hat es sich gezeigt, daß es zur Vermeidung unnötiger Ermüdungserscheinungen vorteilhaft ist, daß die gedachte Achsengeradek der Vorderrollen/ mit der Fußballengelenkachse / zusammenfällt oder etwas unterhalb dieser liegt. Die Abb. 1 der Zeichnung stellt den erster en Fall, Abb. 2 den zweiten Fall dar; Abb. 3 zeigt einen Rollschuh im Augenblick des Abstoßens.When using the roller skate according to the main patent 608 229 it has been shown that it is advantageous to avoid unnecessary symptoms of fatigue that the imaginary straight line k of the front rollers / coincides with the ball of the foot joint axis / or is slightly below this. Fig. 1 of the drawing shows the first case, Fig. 2 shows the second case; Fig. 3 shows a roller skate at the moment of pushing off.

Man kann deutlich erkennen, daß bei dieser neuen und technisch vervollkommneten Konstruktion alle Kennzeichen des Hauptpatentanspruches beibehalten wurden, es ist nur die ideelle Achse h der Vorderrollen / zweckentsprechend tiefer gelegt worden.One can clearly see that with this new and technically perfected construction all the characteristics of the main patent claim have been retained, only the ideal axis h of the front rollers / has been lowered for the purpose.
