Abstract
Description
Patentbeschreibung Patent description
Die Neuerung besteht darin, daß der derzeitig bekannte Rasenmäher, der ja immer durch eine Person vorwärts bewegt werden muß, Jetzt vollkommen automatisch auf dem Rasen läuft ( ohne eine Bekleidperson ).The innovation is that the currently known lawnmower, who always has to be moved forward by a person, now completely automatically running on the lawn (without a clothes person).
Vorteile: 1. Sehr viel Zeitersparniss,man kann entlich seinen Garten geniesen.Advantages: 1. A lot of time savings, you can open your garden enjoy.
2. Gartenfreunde die auf einen englichen Rasen wertlegen, haben entlich die Möglichkeit ohne Sklave ihres Rasens zu werden, ihren Wunsch zu erfüllen.2. Garden lovers who value a narrow lawn have publicly the possibility of fulfilling their wish without becoming a slave to their lawn.
3. Es besteht auch noch die Möglichkeit, durch geringe Abänderungen aus diesem automatischen Rasenmäher einen automatischen Rasensprenger zu machen.3. There is also the possibility of making minor changes turn this automatic lawnmower into an automatic lawn sprinkler.
Auf der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt.Exemplary embodiments of the invention are shown in the drawing.
Fig. 1 veranschaulicht die Konstruktion der Erfindung.Fig. 1 illustrates the construction of the invention.
Von einem Sender 4 der nicht viel größer als eine Zigarettenschachtel ist, werden Elektromagnetische Schwingungen in einer Induktionsschleife 1. gesendet. Die Frequenz ist 9,5 -10 KHedE ( Stöhrungssicher ). Der Kupferdraht 1 wird ca. 5 cm im Boden wellenförmig, in 25 cm Abstand 2 verlegt. Hindernisse wie Bäume 3 Sträucher oder ähnliche, kann nen leicht umgangen werden. Die Verlegung der Induktionsschleife erfolgt relativ einfach und schnalle durch eine Schablone, an der man mit einer art Stichsäge entlang fahren kann. Diese Geräte könnte man dann gegen eine geringe Gebühr bei den Gartencentern ausleihen. From a transmitter 4 that is not much bigger than a packet of cigarettes is, electromagnetic oscillations are sent in an induction loop 1.. The frequency is 9.5-10 KHedE (interference-proof). The copper wire 1 is about 5 cm in the ground undulating, laid at a distance of 25 cm 2. Obstacles like trees 3 bushes or similar, can easily be bypassed. Laying the induction loop is done relatively easily and buckle through a template that you can use with a art jigsaw can drive along. These devices could then be used against a small amount Borrow at the garden centers for a fee.
Die elektromgnetischen Schwingungen werden dann von einem Empfänger 6 der auf den Rasenmäher 5 installiert ist empfangen. Der Empfänger steuert dann die Lenkung des Rasenmähers. Durch Dauermagnetstabalenkung im Empfänger auf die Kupferleitung, wird ein exaktes Nachlaufen des Rasenmähers gewährleistet ( max. Abweichung ca. 1cm ).Der Rasenmähep muß von seiner Konstruktion her nicht so groß sein. The electromagnetic oscillations are then transmitted by a receiver 6 which is installed on the lawn mower 5 is received. The receiver then controls the steering of the lawnmower. By permanent magnet rod steering in the receiver on the Copper line, the lawnmower will continue to run precisely (max. Deviation approx. 1 cm). The construction of the lawn mower does not have to be that big be.
Eine Schnittbreite von ca. 30 cm wäre das Maximum. A cutting width of approx. 30 cm would be the maximum.
Eine Wattsahl von cav 4G0 - 500 Watt wäre voll ausreichend, weil der Rasen öfters geschnitten werden könnte und somit nicht so hoch gewachsen ist, was Ja Kraft einspart. A wattsahl of cav 4G0 - 500 watts would be fully sufficient because the lawn could be cut more often and therefore has not grown so high, which saves energy.
Von der Technik her würde es sich bei einem elektrisch angetriebenen Rasenmäher anbieten, was sich ja in der Praxis schon bestens bewärt hat, 220 V durch einen Umformer auf harmlose 36 V zu verwandeln. Dadurch hat man dann die Möglichkeit ein relativ dünnes Kabel zu verwenden. Das Kabel wUrde sich dann auf einer drehbaren Gabel langsam, je nach Bedarf, vom Rasenmäher abwickeln. In terms of technology, it would be an electrically powered one Offer lawn mowers, which has already proven itself well in practice, 220 V through to convert a converter to harmless 36 V. This then gives you the opportunity to use a relatively thin cable. The cable would then turn on a rotatable Slowly unwind the fork from the lawn mower as required.
Der Rasenmäher der auch einen Grasfangsack bekommt, schaltet sich automatisch ab, wenn der Behälter voll Gras ist. Auch sollte er sich automatisch abschalten, wenn er aus irgend einem Grunde etwas berührt. Der Mäher behommt ringsherum Bügel, die bei Berührung den Motor ausschalten. Das Ideale ist, wenn man den Rasen öfters schneidet sehr wenig Schnittgut anfällt, so daß man meistens sogar den Grasbehälter erst entleeren muß, wenn der Rasen ganz gemäht ist, pig. 2 veranschaulicht die Konstruktion der Schablone. The lawnmower, which also has a grass catcher, switches itself on automatically when the container is full of grass. It should also be automatic switch off if for any reason he touches something. The mower handles around Brackets that switch off the motor when touched. The ideal is when you can see the lawn often cuts very little clippings, so that you usually even the grass container only has to empty when the lawn is completely mowed, pig. 2 illustrates the construction the stencil.
Bestehend aus einem Flachstahlband 1, zwei Bögen 2 und Abstandshalter 3. Eine schablone 4 ermöglicht Bäume, Sträucher, Blumenbeete usw. zu umgehen. Consists of a flat steel strip 1, two arches 2 and Spacer 3. A template 4 enables trees, shrubs, flower beds, etc. to bypass.
Fig. 3 veranschaulicht die Konstruktion des senders 4 und des Empfangers 6.Fig. 3 illustrates the construction of the transmitter 4 and the receiver 6th
