Description
Die bekannten Klingen für Rasierapparate sind eben. Da sie neuerdings sehr dünn ausgeführt werden, haben die freien Schnittkanten nicht mehr die für einen guten und sicheren Schnitt erforderliche Steifigkeit.The well-known blades for razors are flat. Since they recently are made very thin, the free cut edges no longer have what you need good and safe cut required rigidity.
Dieser Nachteil wird durch die Erfindung behoben, indem die Klinge gebogen hergestellt und umgekehrt zur Biegung der Ober- und Unterplatte in den Apparat eingelegt und festgespannt wird. Es ist zum Biegen der Klinge nunmehr eine erheblich größere Kraft erforderlich. Hierdurch wird die innere Spannung des Materials und der Druck, mit dem die Klinge gegen die äußeren Kanten der Unterplatte gedrückt wird, bedeutend erhöht. Die schmalen Schnittkanten werden steifer wie bisher, so daß auch bei sehr dünnen Klingen ein Verbiegen oder Vibrieren beim Rasieren nicht eintritt. Vor allem bei starkem Haar ist der Schnitt dann besser und sicherer. Fig. i zeigt die Lage der Teile eines Rasierapparates im :Mittelschnitt beim Zusammenbau. a ist die gebogene Klinge, b die Unterplatte mit dem Gewindezapfen c und den beiden Führungsstiften d, e die Oberplatte und g der Griff. Fig. z zeigt die Aufsicht der Klinge a und Fig. 3 eine Klinge, die nur an den Kanten gebogen ist.This disadvantage is remedied by the invention by the blade bent and vice versa to the bending of the top and bottom plates in the apparatus is inserted and clamped. It is now a significant amount to bend the blade greater force required. This reduces the internal tension of the material and the pressure with which the blade is pressed against the outer edges of the sub-platen is increased significantly. The narrow cut edges will be stiffer as before, see above that even with very thin blades there is no bending or vibration when shaving entry. The cut is then better and safer, especially with thick hair. Fig. i shows the position of the parts of a razor in: middle section during assembly. a is the curved blade, b the lower plate with the threaded pin c and the two Guide pins d, e the top plate and g the handle. Fig. Z shows the top view of Blade a and Fig. 3 a blade that is only bent at the edges.
