Description
Die bisher aus Kunststoff bestehenden und im Spritzgußverfahren hergestellten Handgriffe für Fahrräder haben zunächst den Nachteil, daß sie sehr teuer sind, da das verbrauchte Kunststoffmaterial kostspielig ist. Außerdem ist die Haltbarkeit dieser Griffe verhältnismäßig gering, da das Material nur wenig elastisch ist. Weiterhin bestehen auch in der-Herstellung erhebliche Schwierigkeiten, die insbesondere in der Kühlung desDornes bestehen, der bei der Herstellung sehr heiß wird.Those previously made of plastic and manufactured by injection molding Handles for bicycles initially have the disadvantage that they are very expensive because the plastic material used is expensive. Plus is the durability these handles are relatively small because the material is not very elastic. Farther there are also considerable difficulties in the production, particularly in the cooling of the mandrel, which becomes very hot during manufacture.
Diese Übelstände werden durch die Erfindung beseitigt; sie besteht darin, daß der neue Handgriff aus der Verbindung einer Papphülse mit aufgespritztem Kunststoff besteht. Bei dieser Ausbildung des Handgriffs können die vorstehend geschilderten Übelstände nicht mehr auftreten. Der Kunststoffanteil des Handgriffs kann verhältnismäßig klein gehalten werden, so daß ein erheblicher Prozentsatz an Kunststoff gespart wird und der Handgriff sich sehr billig herstellen läßt. Die Haltbarkeit der Griffe wird durch die Papphülse günstig beeinflußt,"da der Kunststoffkörper durch das Aufspritzen auf die Papphülse gegen äußere Einwirkungen besser geschützt wird und nicht so leicht zu Bruch geht. Die Elastizität der Papphülse ist diesem Zweck dienlicher als eine Unterlage aus starrem Material, insbesondere Metall. Auch in verfahrenstechnischer Hinsicht ist der bisher bestehende Übelstand beseitigt, denn nunmehr wird durch die umhüllende und damit isolierende Papphülse der Dorn nicht mehr so heiß und läßt sich ohne Schwierigkeit ausreichend kühl halten.These drawbacks are eliminated by the invention; she consists is that the new handle from the connection of a cardboard tube with sprayed Made of plastic. In this design of the handle, the above-described Grievances no longer occur. The plastic part of the handle can be proportionate can be kept small, so that a significant percentage of plastic is saved and the handle can be manufactured very cheaply. The durability of the handles is favorably influenced by the cardboard tube, "because the plastic body is injected on the cardboard tube is better protected against external influences and not so easily breaks. The elasticity of the cardboard tube is more useful for this purpose than one Base made of rigid material, in particular metal. Also in procedural matters Regarding the previously existing deficiency is eliminated, because now is through the enveloping and thus insulating cardboard sleeve is no longer so hot and leaves the thorn keep yourself cool enough without difficulty.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung teilweise im Schnitt dargestellt.In the drawing, an embodiment of the invention is partially shown in section.
Nach der Erfindung besteht der neue Handgriff für Fahr- und Motorräder, Roller usw. aus einer inneren Papphülse a, auf die eine Kunststoffschicht b aufgespritzt ist, so daß das Ganze eine ausreichende Festigkeit hat. Die Befestigung des neuen Handgriffs auf der Lenkstange des Fahrzeuges kann in bisher bekannter Weise erfolgen, d. h. er kann aufgeklebt werden, es können aber auch die an sich bekannten Festklemmmittel im Handgriff vorgesehen sein, so daß der Handgriff wie üblich mit dem Hammer aufgeschlagen werden kann.According to the invention, there is a new handle for bicycles and motorcycles, Roller, etc. from an inner cardboard sleeve a, onto which a plastic layer b is sprayed so that the whole has sufficient strength. Fixing the new one Handle on the handlebar of the vehicle can be done in the previously known manner, d. H. it can be glued on, but the clamping means known per se can also be used be provided in the handle so that the handle is hit with a hammer as usual can be.
