Die Erfindung "betrifft ein Kunst st off-Lauf rad, insbesondere für Rasenmäher oder dergleichen.The invention "relates to a plastic st off-running wheel, in particular for lawn mowers or the like.
Hader für Rasenmäher, Handwagen, Kinderfahrzeuge oder dergleichen werden bisher entweder aus zwei miteinander verschweißten Stahlblechteilen oder ais Kunststoff hergestellt. Bei der Kunststoff-Ausführung weisen die Räder eine zwischen Radnabe und Radumfang angeordnete Scheibe auf, die aus Pestigkeitsgründen beidseitig mit vorstehenden raidalen Rippen bestückt ist. Diese Ausbildung hat insbesondere den Nachteil, daß sich zwischen den Rippen leicht Schmutz festsetzt, der sich nur mühsam entfernen läßt.Hader for lawn mowers, handcarts, children's vehicles or the like have so far either been welded together from two Sheet steel parts or made of plastic. In the plastic version, the wheels have an in between Wheel hub and wheel circumference arranged disc, which for reasons of pestibility Is equipped with protruding raidal ribs on both sides. This training has the particular disadvantage that dirt easily settles between the ribs, which can only be removed with great difficulty.
Durch die Erfindung soll ein Kunststoffrad geschaffen werden, das einfach und kostengünstig herstellbar ist, das guteElastizitätseigenschaffen aufweist und wenig verschmutzt.The invention aims to create a plastic wheel that is simple and inexpensive to manufacture, that has good elasticity properties and that is not soiled.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst worden, daß das Kunststoffrad als Hohlkammerrad ausgebildet ist, wobei die Kammerhälften durch Rotationsschweißung miteinander verbunden sind.According to the invention, this object has been achieved by that the plastic wheel is designed as a hollow chamber wheel, the chamber halves being rotationally welded to one another are connected.
- In dieser Ausführung ist das Kunststoffrad mit niedri-- In this version, the plastic wheel has a low

gen Kosten herstellbar. Die Rotationsschweißung kann beispielsweise auf einer herkömmlichen Bohrmaschine durchgeführt werden, so daß keine Kunst stoff Schweißvorrichtungen erforderlich sind. Die Hohlkammerform "bewirkt einerseits eine hohe Festigkeit und ermöglicht andererseits eine an den Seiten glatte Bauweise.can be produced at low cost. The rotation welding can for example performed on a conventional drill so that no plastic welding devices are required. The hollow chamber shape "causes on the one hand a high strength and on the other hand enables one on the sides smooth construction.
Gemäß einer Weiterbildung der Erfindung kann die ^abe des Rades gegenüber der Lauffläche in axialer Richtung versetzt angeordnet sein. Dadurch wird bei geeigneter Formgebung der beiden ICammerhälften die Gesamtelastizität des Rades gegen radiale Stöße erhöht. Das Rad kann ferner längs seiner Lauffläche mit einer zusätzlichen stoßdämpfenden Kunststoff -Beschichtung versehen sein, wodurch auch die Rollgeräusche herabgesetzt weiden.According to a development of the invention, the ^ abe of the wheel can be arranged offset in the axial direction with respect to the running surface. This is with appropriate shaping of the two halves of the chamber determine the overall elasticity of the wheel increased against radial impacts. The wheel can also have an additional shock-absorbing plastic along its tread -Coating, which also reduces rolling noise.
Als Werkstoff kann ein Niederdruck-Polyäthylen geeigneter Härte und in gewünschter Farbe verwendet werden. Die Laufflächen-Beschichtung kann aus einem gummiähnlichen Hochdruck-Polyäthylen bestehen.A low-pressure polyethylene of suitable hardness and in the desired color can be used as the material. the Tread coating can be made from a rubber-like high-pressure polyethylene exist.
Ein Ausführungsbeispiel der Erfindung,aus dem sich weitere erfinderische Merkmale ergeben, ist in der Zeichnung dargestellt. Eszeigen:An embodiment of the invention from which further Inventive features result is shown in the drawing. Show it:

Das abgebildete Laufrad ist aus zwei Kammern 1 und 2 zu-The impeller shown is made up of two chambers 1 and 2.

sammengesetzt, iind zwar sind beide Kammern in der Lauffläche 3 und in der Habe 4 bei S miteinander verschweißt. Diese Schweißung ist als Rotiationsschweißung ausgeführt. Die Habe 4 ist gegenüber der LauffIäche3'in axialer Richtung außermittig angeordnet, also versetzt. Die durch Zusammenschweißen der beiden Hohlkammerhäflten gebildete Lauffläche ist mit einer Kunststoff-Beschichtung 5 aus einem stoßdämpfenden Kunststoff abgedeckt, die vorzugsweise aufgespritzt wird.composed, although both chambers are in the running surface 3 and welded to each other in the hat 4 at S. This weld is carried out as a rotation weld. The property is 4 eccentric in the axial direction with respect to the running surface 3 ' arranged, so offset. The running surface formed by welding the two Hohlkammerhäflten is with a Plastic coating 5 made of a shock-absorbing plastic covered, which is preferably sprayed on.
