Description
BESCHREIBUNGDESCRIPTION
Der Erfindung liegt die Aufgabe zugrunde, handelsübliche elektrische Rahenmäher mit horizontal routierenden Schneidmessern so zu verändern, daß deren Funktion über das alleinige Rasen schneiden hinaus, zusätzlich zu einem Vertikutierer ( Bodenlüfter ) erweitert werden kann.The invention is based on the object of modifying commercially available electric frame mowers with horizontally rotating cutting blades in such a way that their function can be expanded beyond just mowing the lawn to include a scarifier (soil aerator).
Bekannt sind verschiedene Patent,- bzw. gebrauchsmustergeschützte Anmeldungen, welche aber alle nicht über sichelförmige Metallbolzen verfügen.Various patent and utility model applications are known, but none of them have sickle-shaped metal bolts.
Diese Aufgabe wird erfindungsmemäß dadurch gelöst, daß mindestens ein sichelförmiger Metallbolzen, welcher an der dem Boden zugewandten Unterseite des Schneidmessers herausragt und in den Boden eindringt, daß zusätzliche Vertikutieren des Rasens ermöglicht, wobwei auch die bei diesem Arbeitsgang anfallenden Wurzelbestandteile des Rasens,- wie auch die beim gleichzeitigen Schneidvorgang anfallenden Rasenabfalle, auf normalen Wege in den Fangkorb geschleudert werden.This object is achieved according to the invention in that at least one sickle-shaped metal bolt, which protrudes from the underside of the cutting blade facing the ground and penetrates into the ground, enables additional scarification of the lawn, whereby the root components of the lawn arising during this operation - as well as the lawn waste arising during the simultaneous cutting process - are thrown into the collecting basket in the normal way.
Die in den Boden eindringenden sichelförmigen Metallbolzen, welche im Bereich der beiden äußeren Enden des Schneidmessers angebracht sind, verrichten durch die Rotation des drehenden Messers und das Fortbewegen des Rasenmähers, den zusätzlichen Vertikutiervorgang. Als besonders vorteilhaft ist die konische.- d.h. sich nach unten hin verjüngende Form Metallbolzens, der dazu noch sichelförmig gestaltet ist. Diese Konstruktionsform gewährleistet, daß der Sichelwiderstand von der Spitze aus, allmählich nach obenhin zunimmt, daß hat zum Vorteil, daß der Rasen schonender behandeltwird und das die auf den Rasenmähermotor einwirkenden Wiederstandskräfte geringer sind. Nach dem Lüften ist das Schneidmesser auszuwechseln, oder die Metallbolzen auszubauen.The sickle-shaped metal bolts that penetrate the ground and are attached to the two outer ends of the cutting blade carry out the additional scarification process through the rotation of the rotating blade and the movement of the lawnmower. The conical shape of the metal bolt, which is also designed in a sickle shape, is particularly advantageous. This design ensures that the sickle resistance increases gradually from the tip to the top, which has the advantage that the lawn is treated more gently and that the resistance forces acting on the lawnmower engine are lower. After aeration, the cutting blade must be replaced or the metal bolts removed.
Die Erfindung wird nachfolgend anhand der Zeichnung des näheren erläutert.The invention is explained in more detail below with reference to the drawing.
Fig. 1 zeigt einen mit einem Gewinde 3, versehenen sichelförmigen Metallbolzen 1, welcher in die Vierkantöffnungen 8, des in Fig. 2 als Draufsicht dargestellten Schneidmessers 7, eingesetzt,- und entspr. Fig. 1, mittels einer Schraubenmutter 5, und einer zwischenliegenden Unterlegscheibe 4, festgeschraubt werden.Fig. 1 shows a sickle-shaped metal bolt 1 provided with a thread 3, which is inserted into the square openings 8 of the cutting blade 7 shown in Fig. 2 as a top view, and is screwed tight as shown in Fig. 1 by means of a screw nut 5 and an intermediate washer 4.
Fig. 2 zeigt ein handelsübliches Schneidmesser 7, in dessem äußerem Bereich, zusätzlich 2 Stk. Vierkantöffnungen 8, zur Einbringung des Metallbolzens 1, passend zu Vierkant 2, eingearbeitet sind.Fig. 2 shows a commercially available cutting blade 7, in the outer area of which two additional square openings 8 are incorporated for the insertion of the metal bolt 1, matching the square 2 .
Fig. 3 zeigt ein handelsübliches Schneidmesser 7, in der Seitenansicht mit hier beispielsweise 2 Stk. montierten sichelförmige Metallbolzen I5 welche im Bereich der äußeren Enden des Schneidmessers anmontiert sind.Fig. 3 shows a commercially available cutting blade 7, in side view with, for example, two crescent-shaped metal bolts I 5 mounted in the area of the outer ends of the cutting blade.
Fig. 4 zeigt ein handelsübliches Schneidmesser 7, in der Draufsicht, mit von unten hier beispielsweise 2 Stk. sichelförmige Metallbolzen 1, bei welchem die Schraubenmuttern 5, die in diesem Falle als Befestigungsmöglichkeit gewählt wurde,- zu erkennen sind.Fig. 4 shows a commercially available cutting blade 7, in plan view, with, from below, for example, 2 pieces of sickle-shaped metal bolts 1, in which the screw nuts 5, which in this case were chosen as a fastening option, can be seen.
