Abstract
Description
Bekannt sind von menschlicher Kraft betriebene Handrasenmäher welche mittels eines Holmes (Fig. I, Nr. 8) den Handrasenmäher vorwärts bewegen. Durch die Vorwärtsbewegung rotieren die Antriebsräder (Fig. I, Nr. 6). Innen in den Antriebsrädern (Fig. I, Nr. 6) sind Zahnkränze (Fig. I, Nr. 7) vorhanden, welche die Ritzel (Fig. I, Nr. 4) antreiben. Diese Ritzel (Fig. I, Nr. 4) treiben über Mitnehmerkeile (Fig. I, Nr. 5) den Mäh-Schneidezylinder (Fig. I, Nr. 1) an. Dieser Mäh-Schneidezylinder ist ringsum versehen mit spiralförmigen Stahlmessern (Fig. I, Nr. 2). Bei der Rotierung des Mäh-Schneidezylinders (Fig. I, Nr. 1) reiben diese Stahl messer (Fig. I, Nr. 2) gegen ein feststehendes Gegenmesser (Fig. I, Nr. 3).Hand lawn mowers operated by human power are known which move the hand lawn mower forward by means of a spar ( Fig. I, No. 8 ). Due to the forward movement, the drive wheels rotate ( Fig. I, No. 6 ). Inside the drive wheels ( Fig. I, No. 6 ) there are sprockets ( Fig. I, No. 7 ) which drive the pinion ( Fig. I, No. 4 ). These pinions ( Fig. I, No. 4 ) drive the mowing-cutting cylinder ( Fig. I, No. 1 ) via driver wedges ( Fig. I, No. 5 ). This mowing-cutting cylinder is provided with spiral steel knives all around ( Fig. I, No. 2 ). When the mowing cutting cylinder ( Fig. I, No. 1 ) rotates, these steel knives ( Fig. I, No. 2 ) rub against a fixed counter knife ( Fig. I, No. 3 ).
Das Mähen mit einem herkömmlichen Handrasenmäher, wie oben beschrieben, ist deshalb beschwerlich, weil mittels mensch licher Kraftaufwendung der Mäh-Schneidezylinder (Fig. I, Nr. 1) in rotierender Bewegung gebracht werden muß.Mowing with a conventional manual lawn mower, as described above, is difficult because the mowing cutting cylinder ( Fig. I, No. 1 ) must be brought into rotating motion by means of human effort.
Die Erfindung soll hier Abhilfe schaffen. Statt mit mensch licher Kraftaufwendung, wie beim herkömmlichen Handrasenmäher, wird der Mäh-Schneidezylinder (Fig. II, Nr. 1) durch die Erfindung elektrisch betrieben. Nach der Erfindung wird der Mäh-Schneide zylinder (Fig. II, Nr. 1) durch einen Elektro-Außenläufermotor angetrieben.The invention is intended to remedy this. Instead of using human force, as in the conventional manual lawnmower, the mowing cutting cylinder ( Fig. II, No. 1 ) is operated electrically by the invention. According to the invention, the mowing-cutting cylinder ( Fig. II, No. 1 ) is driven by an electric external rotor motor.
Bei dem Außenläufer-Elektromotor steht, im Gegensatz zu den gebräuchlichen Elektromotoren bei den die Motorwelle rotiert, die Motorachse fest und es rotiert das Motorgehäuse um die Motorachse.The external rotor electric motor stands in contrast to the common electric motors in which the motor shaft rotates, the motor axis and it rotates the motor housing around the Motor axis.
Bei dieser Erfindung werden um das Gehäuse vom Außenläufer- Elektromotor (Fig. II, Nr. 1) spiralförmige Stahlmesser (Fig. II, Nr. 2) angebracht, welche gegen ein feststehendes Gegenmesser (Fig. II, Nr. 3) reiben und somit Gras von der Rasenfläche abschneiden.In this invention, around the housing of the external rotor electric motor ( Fig. II, No. 1 ) spiral steel knives ( Fig. II, No. 2 ) are attached, which rub against a fixed counter knife ( Fig. II, No. 3 ) and thus Cut grass off the lawn.
Durch den elektrischen Antrieb des Mäh-Schneidezylinders (Fig. II, Nr. 1) mittels eines Elektro-Außenläufermotors, ist das Mähen mit einem Handrasenmäher wesentlich leichter.Due to the electric drive of the mowing cutting cylinder ( Fig. II, No. 1 ) by means of an electric external rotor motor, mowing with a hand lawn mower is much easier.
