Description

Luftpumpe Die Erfindung betrifft eine Luftpumpe derjenigen Art, bei der ein Fahrzeugrahmenrohr als Pumpenzylinder für einen glockenförmigen, elastischen und durch federnde Mittel ausgedehnten Kolben dient. Das Wesen der Erfindung besteht darin, daß die untere der beiden den Kolben zwischen sich festklemmenden Platten mit radialen, sich der Inn:enumfläche des Kolbens anpassenden federnden Zungen versehen ist. Durch diese Anordnung wird ein ständig festes und dichtes Anliegen des glockenförmigen Kolbens an dem Rahmenrohr ermöglicht, auch wenn dessen Innenfläche Ungleichmäßigkeiten und Abweichungen vom genau kreisförmigem Querschnitt aufweist.Air pump The invention relates to an air pump of the type at a vehicle frame tube as a pump cylinder for a bell-shaped, elastic and piston is extended by resilient means. The essence of the invention consists in that the lower of the two plates clamping the piston between them provided with radial resilient tongues that adapt to the inner surface of the piston is. This arrangement ensures a constantly firm and tight fit of the bell-shaped Piston on the frame tube allows, even if its inner surface irregularities and has deviations from the precisely circular cross-section.

Die federnden Zungen gemäß der Erfindung können noch lose mit einer Ringfeder verbunden sein, welche sich ihrerseits von innen gegen den glockenförmigen Kolben legt.The resilient tongues according to the invention can still be loose with a Ring spring connected, which in turn is from the inside against the bell-shaped Piston lays.

In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel veranschaulicht, und zwar zeigt Abb. i die in einem Rahmenrohr des Fahrzeugs angeordnete Pumpe- im Längsschnitt durch das Rahmenrohr, Abb.2 einen Längsschnitt durch den Kolben und die Kolbenstange in größerem Maßstabe, Abb. 3 die Platte des Kolbens mit den federnden Zungen in gespreiztem Zustande in grö-. ßerem Maßstabe und Abb. 4 eine Einzelheit in noch größerem Maßstabe.In the drawing, the invention is illustrated using an exemplary embodiment, namely Fig. i shows the pump arranged in a frame tube of the vehicle Longitudinal section through the frame tube, Fig. 2 a longitudinal section through the piston and the piston rod on a larger scale, Fig. 3 the plate of the piston with the resilient Tongues in the spread state in large. Larger scale and Fig. 4 a detail on an even larger scale.

Das zur Anordnung der Pumpe dienende Rahmenrohr i des Fahrzeuges ist oben mit einem Verstärkungsfutter ia versehen. Das Rohr i wird unten durch einen an der Oberseite mit einer Vertiefung versehenen Gummipfropfen 7 o. dgl. verschlossen. Die darin bewegliche Kolbenstange 5 trägt einen in der Längsrichtung verschiebbaren Griffteil 6. Der glockenförmige biegsame Kolben sitzt zwischen zwei Platten 9 und i o an einem in der Kolbenstange befestigten Bolzen 12. Die Platte i o ist mit federnden Zungen 13 versehen, die gemäß Abb. 3 mit der Platte io aus einem Stück Federstahl o. dgl. von geeigneter Elastizität geformt sein können..The frame tube i of the vehicle, which is used to arrange the pump, is provided at the top with a reinforcing lining ia. The tube i is closed at the bottom by a rubber stopper 7 or the like provided with a recess on the top. The piston rod 5 movable therein carries a handle part 6 that can be moved in the longitudinal direction. The bell-shaped flexible piston sits between two plates 9 and io on a bolt 12 fastened in the piston rod 12. The plate io is provided with resilient tongues 13, which according to FIG the plate io can be formed from a piece of spring steel or the like of suitable elasticity.

Auf Wunsch können die Zungen 13 mittels an ihrem Außenrand ausgebildeter Ösen i3-mit einem frei federnden Ring 15 .(Abb. ¢) lose verbunden werden, der sich dann seinerseits gegen die Innenfläche des glockenförmigen biegsamen Kolbens i i legt. If desired, the tongues 13 can be loosely connected to a freely resilient ring 15 (Fig. ¢) by means of eyelets i3- formed on their outer edge, which in turn then lies against the inner surface of the bell-shaped flexible piston ii.

Der untere Teil 16 der röhrenförmigen Kolbenstange 5 ist teleskopartig im oberen verschiebbar, um die Länge der Kolbenstange Rahmenruhren von verschiedener Länge- anpassen zu können. Der Pumpenschlauch 2i ist durch eine Öffnung an der Decke des Griffteils 6 in die hohle Kolbenstange 5 einführbar, so daß er hier aufbewahrt werden kann. Das obere Ende des Schlauches kann beispielsweise mittels Gewinde in der erwähnten Öffnung am Handgriff befestigt werden.The lower portion 1 6 of the tubular piston rod 5 is telescopically displaceable in the top, to adapt frame clocks of different length-to the length of the piston rod. The pump hose 2i can be inserted into the hollow piston rod 5 through an opening in the ceiling of the handle part 6, so that it can be stored here. The upper end of the hose can be attached to the handle, for example by means of a thread in the opening mentioned.
