Abstract

The device has a spiral or similarly shaped blade (b) on the external rotor roller which cuts against a holed or slitted cutting plate (c) of half-round shape over an angle of up to 180 degrees. The device uses an asynchronous motor, a synchronous motor or a piezoelectric motor. The blade can be sintered and of trapezoidal shape and can be automatically re-sharpened. The blade is pressed against the plate by a centrifugal force.

Description

Die Erfindung bezieht sich auf einen Rasier- und Schneide­ apparat mit einem Außenläufermotor und schneckenförmig an­ gebrachten Schermesser. Hierdurch wird ein sauberes, rupf­ freies Abscheren z. B. von Barthaaren, Teppich- oder Fell­ haaren und dergleichen ermöglicht.The invention relates to a shaving and cutting edge apparatus with an external rotor motor and helical brought shear knife. This will make a clean, plucked one free shear z. B. of whiskers, carpet or fur hair and the like.

Der saubere, fast geräuschfreie Lauf des Außenläufermotors ist ein weiterer Vorteil dieser Erfindung.The clean, almost noiseless running of the external rotor motor is another advantage of this invention.

STAND DER TECHNIKSTATE OF THE ART

Bekannt sind derartige Geräte hauptsächlich nach dem Schwingankerprinzip, d. h. ein Scherkopf schneidet von einer Seite zur anderen die durch ein Scherblatt (Loch­ blech) vorstehenden Haare ab. Hierbei handelt es sich mehr oder weniger um ein "Abhacken" von Haaren, was u. a. mit lautem Geräusch (Schwinganker) und Unverträglichkeit der Haut verbunden ist, ganz gleich, ob diese Geräte im Netz- oder Batterie-Betrieb angetrieben werden. Bekannt sind ebenfalls derartige Geräte mit kleinen, aber eben­ falls nur in einer Ebene rotierenden Schermessern.Such devices are mainly known after Rocker armature principle, d. H. a shaving head cuts from one side to the other through a foil (hole sheet) protruding hair. This is it more or less about a "chopping off" of hair, which u. a. with loud noise (swing armature) and intolerance the skin is connected, no matter whether these devices in the Mains or battery operated. Known are also such devices with small, but just if only shear knives rotating in one plane.

ERFINDUNGSAUFGABEINVENTION TASK

Der Erfindung liegt die Aufgabe zugrunde, bekannte Rasierer oder Haarschneidegeräte derart umzukonstruieren, daß ein Außenläufermotor (Fig. 1a) mit einem geformten Messer (Fig. 1b) die Schneidearbeit - nicht nur in einer Ebene -, sondern in einem Halbkreis bis zu 180° gegen ein gelochtes Scherblatt (Fig. 1c) übernimmt, ähnlich dem Prinzip eines Rasenmähers oder Walzenlüfters.The invention has for its object to redesign known shavers or hair clippers such that an external rotor motor ( Fig. 1a) with a shaped knife ( Fig. 1b) the cutting work - not only in one plane - but in a semicircle up to 180 ° a perforated shear blade ( Fig. 1c) takes over, similar to the principle of a lawn mower or roller blower.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Außenläufer- oder Käfigankermotor Verwendung findet an dessen Außenrotor (Fig. 1a) ein spiralförmiges Messer (Fig. 1b) angebracht ist oder Messerstäbe (Fig. 3b) Ver­ wendung finden.The object is achieved in that an external rotor or cage anchor motor is used on the outer rotor ( Fig. 1a), a spiral knife ( Fig. 1b) is attached or knife bars ( Fig. 3b) Ver use.

Bei dem Außenläufermotor (Fig. 2) ist der sonst üblich innenliegende Rotor (d) hier als Stator ausgebildet und fest montiert, wobei sich die Außenwalze (a) um den Rotor (d) dreht.In the external rotor motor ( FIG. 2), the otherwise usually internal rotor (d) is designed here as a stator and is permanently mounted, the outer roller (a) rotating around the rotor (d).

Ebenso ist ein Kleinmotor (e) mit einer am Rotor befestig­ ten Walze, ähnlich dem eines Walzenlüfters und Gegenlage­ rung konstruierbar.A small motor (s) is also attached to the rotor with one th roller, similar to that of a roller fan and counterpart constructable.

Apparatus according to claim 1, 2 + 3, characterized in that the trapezoidal shear blades ( Fig. 3b) are pressed by the centrifugal force and loose storage against the shear blade and can thus be constantly re-sharpened and replaced. 5. Gerät nach Anspruch 1, 2, 3 + 4, dadurch gekennzeichnet, daß der Motor mit Wechsel- oder Gleichspannung betrieben wird und die Umdrehungszahl geregelt werden kann.5. Apparatus according to claim 1, 2, 3 + 4, characterized in that the motor is operated with AC or DC voltage and the number of revolutions can be regulated. 6. Gerät nach Anspruch 1, 2, 3, 4 + 5, dadurch gekennzeichnet, daß die Schermesseer auf der Walze (Fig. 3) in Längs­ richtung angebracht werden.6. Apparatus according to claim 1, 2, 3, 4 + 5, characterized in that the shear blades on the roller ( Fig. 3) are attached in the longitudinal direction. 7. Gerät nach Anspruch 1, 2, 3, 4, 5 + 6, dadurch gekenn­ zeichnet, daß die Außenläuferwalze zu Reinigungszwecken steckbar ausgeführt wird.7.
