Description

DEUTSCHESGERMAN

Scherfolien, für Trockenrasiergeräte, auf deren Innenseite Messer kreisen oder sich hin- und herbewegen, weisen außerordentlich geringe Wandstärke von Bruchteilen eines Millimeters auf und bedürfen infolgedessen einer umfassenden Versteifung, z. B. in Form eines Halteringes. Bei bekannten Geräten ist der Umfang der Scherfolie durch den eingebördelten Haltering umfaßt. Bei diesen besteht die Möglichkeit, daß die Metallscherfolie durch den Druck der kreisenden Messer oder beim Aufschrauben des Halteringes auf das Gerät unter Faltenbildung verdreht wird.Shaving foils, for dry razors, on the inside of which knives circle or move back and forth, have an extremely thin wall thickness of fractions of a millimeter and require consequently a comprehensive stiffening, e.g. B. in the form of a retaining ring. In known devices is the circumference of the shaving foil is encompassed by the crimped retaining ring. With these there is the possibility that the metal shear foil by the pressure of the rotating knife or when screwing on the retaining ring is twisted onto the device with the formation of creases.

Es ist bekannt, bei Scheren die Schneiden aus anderem Material herzustellen als den eigentlichen Scherenkörper, diesen z. B. aus Kunstharz. Die Schneidblätter aus Stahl sind dabei auf den Kunstharzarmen befestigt, und zum Zwecke der Befestigung sind die Schneidblätter mit Durchbrechungen versehen, in die beim Pressen der Kunstharzarme das Material eintritt und die gegenseitige Verbindung sichert. Hier liegt nicht die Aufgabe vor, eine gegenseitige Verdrehung der Scherplatte und der miteinander vereinigten Teile auszuschließen. Auch liegen die miteinander vereinigten Teile parallel und übereinander. It is known that the cutting edges of scissors are made of a different material than the actual material Scissors body, this z. B. made of synthetic resin. The steel cutting blades are on the synthetic resin arms attached, and for the purpose of attachment, the cutting blades are perforated provided, into which the material enters when the synthetic resin arms are pressed and the mutual connection secures. The task here is not a mutual twisting of the shear plate and of each other to exclude united parts. The parts that are united with one another also lie parallel and one above the other.

Die Erfindung trägt dem dadurch Rechnung, daß die Scherfolie in der Nähe ihres Umfangs Randdurchbrechungen aufweist und daß sie dadurch fest in die Wandung des Halteringes aus Kunstharz- oder Metallspritzguß eingebettet ist, daß das Guß- oder Spritzmaterial die Randdurchbrechungen in an sich bekannter Weise mit beim Guß entstandenen Haltezapfen durchsetzt. Damit ist ein sicherer Halt der Scherplatte im Haltering gewährleistet. Eine Verdrehung der Scherplatte im Haltering unter Bildung von Falten wird vermieden, da das die Durchbrechungen der Scherplatte durchsetzende Guß- oder Spritzmaterial für eine genügende Fixierung sorgt.The invention takes this into account in that the shaving foil has edge perforations in the vicinity of its circumference has and that they are thereby firmly in the wall of the retaining ring made of synthetic resin or Metal injection molding is embedded that the casting or injection molding material has the edge perforations in itself as is known, interspersed with retaining pegs formed during casting. This is a secure hold of the Shear plate guaranteed in the retaining ring. A twisting of the shear plate in the retaining ring with formation wrinkles are avoided, since the cast or injection-molded material penetrating the perforations in the shear plate ensures sufficient fixation.

Die Zeichnung zeigt eine Ausführungsform einer erfindungsgemäßen Scherplatte, und zwarThe drawing shows an embodiment of a shear plate according to the invention, namely

Die Scherfolie 1, auf deren Unterseite der mit Ringwülsten 2 versehene Messerträger 4 kreist, trägt in der Nähe ihres Umfanges Durchbrechungen 5. Der Durch einen Haltering gehaltene Scherfolie für TrockenrasiergeräteThe shaving foil 1, on the underside of which the knife carrier 4 provided with annular beads 2 circles, carries perforations in the vicinity of its circumference 5. The one held by a retaining ring Shaving foil for dry razors

Umfang der Scherfolie 1 greift in einen Haltering 6 aus Kunstharz- oder Metallspritzguß ein. Bei Herstellung in Guß werden die Durchbrechungen 5 der Scherfolie 1 von dem fließenden Material ausgefüllt. So ergeben sich aus dem Gußmaterial bestehende Haltezapfen, welche die Durchbrechungen 5 durchsetzen. Sie schließen die Faltenbildung der Scherfolie 1 beim Gebrauch des Gerätes aus.The circumference of the shaving foil 1 engages in a retaining ring 6 made of synthetic resin or metal injection molding. At manufacture In casting, the openings 5 in the shaving foil 1 are filled with the flowing material. This results in retaining pegs that are made of the cast material and penetrate the openings 5. They exclude the formation of creases in the shaving foil 1 when using the device.
