Description

Elektrisch betriebener Rasenmäher Die Erfindung bezieht sich auf einen elektrisch betriebenen Rasenmäher. Electrically powered lawn mower The invention relates to an electrically powered lawn mower.

Bei Rasenmähern der vorgenannten Art ist ein Zuleitungskabel für den elektrischen Strom vorhanden. Dieses Kabel ist bei Betrieb von der Haus-Steckdose bis zum Netzanschluß am Rasenmäher geführt.When lawnmowers of the aforementioned type is a supply cable for the electric current available. This cable is when operated from the house socket to the mains connection on the lawnmower.

Bei Betrieb, insbesondere in unebenem, schrägen Gelände ist darauf zu achten, daß die Stromzuleitung nicht von den Schneidmessern des Rasenmähers angeschnitten wird.When operating, especially on uneven, sloping terrain, care must be taken Make sure that the power supply line is not cut by the cutting blades of the lawn mower will.

Aber auch bei normalem Betrieb ist darauf zu achten, daß die Stromzuleitung nicht beschädigt wird. Trotz erhöhter Aufmerksamkeit sind Beschädigungen in der Zuleitung nicht zu vermeiden.But even with normal operation it is important to ensure that the power supply will not be damaged. Despite careful attention, there is damage in the Feed line cannot be avoided.

Bei Anschneiden des Zuleitungskabels oder bei sonstigen Beschädigungen, die zur Freilegung einer oder mehrerer Stromadern führen, kommt es leicht zu Unfällen. ZbB.kann die Bedienungsperson die freigelegte Stromader berühren; auch kann die freigelegte Stromader bei Umlegen des Kabels stromleitende Teile des Rasenmähers berühren, so daß dann das ganze Gerät unter Strom gesetzt wird.If the supply cable is cut or if there is any other damage, which lead to the exposure of one or more power lines, accidents easily occur. For example, the operator can touch the exposed power line; also can exposed power line when the cable is turned over, conductive parts of the lawnmower touch so that the whole device is then energized.

Die vorliegende Erfindung hat sich die Aufgabe gestellt, einen elektrisch betriebenen Rasenmäher zu schaffen, bei dem im Falle einer Beschädigung des Stromzuleitungskabels mit Auftreten eines geringen Fehlerstromes die Spannung sofort unterbrochen wird.The present invention has the task of providing an electrically operated lawn mower, in the event of damage to the power supply cable when a small fault current occurs, the voltage is interrupted immediately.

Zur Lösung dieser Aufgabe wird nach der Erfindung die Verwendung eines Fehlerstromschutzschalters in der von der Steckdose zum Netzanschluß am Rasenmäher geführten Zuleitung für den elektrischen Strom vorgeschlagen.To solve this problem, according to the invention, the use of a Residual current circuit breaker in the from the socket to the mains connection on the lawn mower Proposed led supply line for the electric current.

Der Vorteil, der mit der Erfindung erreicht wird besteht darin, daß bei Beschädigungen am Zuleitungskabel für die Bedienungsperson keine Gefahr mehr auftritt. Die Bedienungsperson kann ohneweiteres eine freigelegte Stromader berühren, weil dann sofort infolge Fließens eines geringen Stromes der Schutzschalter anspricht und die anliegende Spannung unterbricht. Gleiches gilt für den Fall, daß eine freigelegte Stromader mit stromleitenden Teilen des Rasenmähers in Berührung kommt. Mit der vorliegenden Erfindung werden also Unfälle,die durch freigelegte Stromadern auftreten können, gänzlich vermieden.The advantage that is achieved with the invention is that there is no longer any danger for the operator if the supply cable is damaged occurs. The operator can easily touch an exposed power line, because then the circuit breaker responds immediately as a result of the flow of a small current and the applied voltage is interrupted. The same applies in the event that an exposed Stromader comes into contact with electrically conductive parts of the lawnmower. With the The present invention is therefore accidents that occur due to exposed power lines can be avoided entirely.
