Description
Bei Motormähern der Siehelbauart, bei we£«ber die angetriebene Welle in den Gehäuse des Rasenmähers angeordnet ist und an ihre» unteren Ende den «dt beher zahl tunlaufenden Messerbalken trägt, ist es bekannt, a Enden des Messerbalkens auswechselbare StahlIcIIngen bringen. Bei einer gebräuchlichen Bauart sind die«· in Fo eines gleichseitigen Dreiecke gestalteten Messerkl einen verhältnismäßig starken Stahlblech gesä träglich geschliffen· Wenn die Schärfe solcher KI läßt, wird von ihnen das Gras nur noeh abgesehlagea, nicht sehr abgeschnitten. Die Sonneidleistung mindert. Die bekannten Messer sind zwar an dem Messerbalkens angeschraubt, so daß dl· Klinge» Schneidkante stunpf geworden 1st, naoh Lösen der Befestigungsschrauben gedreht und mit den noeh unbenutztes Seimeidkanten weiterverwendet werden kann. Schließlich die Klinge ausgewechselt werden.With motor mowers of the Siehel type, with we £ «over the driven shaft is arranged in the housing of the lawnmower and at its "lower end the" dt harbor number of running knife bar carries, it is known a Ends of the cutter bar exchangeable steel icings bring. In a common design, the «· in Fo An equilateral triangle shaped knife class a relatively strong sheet steel wearily honed · If the sharpness of such KI leaves, the grass is only cut off from them, not very cut off. The sun performance diminishes. The known knives are screwed onto the knife bar so that the · blade » The cutting edge has become stunted, after loosening the fastening screws turned and with the unused silk edge can be reused. In the end the blade can be replaced.
Die Neuerung sieht eine Gestaltung eines solchen Ural nessers vor, bei welcher die Messerklinge aus Yesfe mäßig dünnem Federstahl besteht· so daß eine große und fur einen längen Zeltraum gleichbleibende SchneidleistungThe innovation sees a design of such an Urals nessers, in which the knife blade from Yesfe moderately thin spring steel is made · so that a large and fur Constant cutting performance over a length of tent space
leistet ist. Andererseits ist durch die besondere Gestaltung der Klinge die Gefahr vermieden, daß der dünne Federstahl allzu leicht abbrechen kann. Schließlieh zeichnet sich die neue Gestaltung der Messerklinge durch geringes Gewicht und niedrige Fertigungskosten aus.is performing. On the other hand, the special design of the blade avoids the risk of the thin spring steel can break off too easily. Finally, the new design of the knife blade is characterized by its low weight and low manufacturing costs.
Ein Ausführungsbeispiel der Neuerung wird an Hand der Zeichnung beschrieben. In der Zeichnung zeigen:An embodiment of the innovation is described with reference to the drawing. In the drawing show:
Abb. 1 eine Draufsicht undFig. 1 is a plan view and
Abb. 2 einen Schnitt durch eine gemäß der Neuerung ausgebildete Messerklinge*Fig. 2 a section through a knife blade designed according to the innovation *
Wie aus der Zeichnung ersichtlich, besteht die Klinge aus einem dreiecksförmig gestalteten Federstahlblatt 1 von etwa 0,2 mm Stärke, welches in eine Trägerplatte 2 eingebettet ist. Die Trägerplatte kann aus einem Metall, wie z.B. aus einer Zinklegierung oder aus Kunststoff bestehen, und as kann die Trägerplatte in diesem Falle in einer Spritzform gespritzt und dabei das Federstahlblatt miteingespritzt werden; der ringsum hervorstehende Randbereich des Stahlblattes bildet die Messerschneide.As can be seen from the drawing, the blade consists of a triangular spring steel sheet 1 of about 0.2 mm thick, which is embedded in a carrier plate 2. The carrier plate can be made of a metal such as a zinc alloy or plastic, and as can be the carrier plate in this case in an injection mold injected and at the same time the spring steel sheet is injected; the all around protruding edge area of the steel sheet forms the knife edge.
Die Trägerplatte kann jedoch auch aus zwei Platten 2 und 2' bestehen, die unter Zwischenlage des Federstahlblattes 1 aufeinandergelegt und durch Verschweißung oder Kleben miteinander vereinigt werden. Die zum Anschrauben der Dreiecksklinge erforderlichen Löcher werden durchgehend in der Trägerplatte und in dem Federstahlblatt ausgespart. Sie können auch dazu ausgenutzt werden, um bei einer zweiteiligen Trägerplatte die beiden Hälften und das dazwischenliegende Federstahlblatt mittels Hohlnieten miteinander zu vereinigen.The carrier plate can, however, also consist of two plates 2 and 2 ' exist, which are placed on top of one another with the interposition of the spring steel sheet 1 and by welding or gluing together be united. The holes required to screw on the triangular blade are made through the Carrier plate and recessed in the spring steel sheet. They can also be used to help with a two-part Carrier plate to unite the two halves and the spring steel sheet in between by means of hollow rivets.
