Description

Die Erfindung betrifft eine Schmiervorrichtung für Fahrräder und ähnliche Fahrzeuge und besteht im wesentlichen darin, daß die Druckfettschmierung für ein oder mehrere Schmierstellen des Rades von an oder in der Nähe dieser Schmierstellen angebrachten Nippeln erfolgt; das gilt insbesondere für den Steuerkopf und das Tretlager, deren getrennte Schmierung den Vorteil bringt, daß die durch das Unterrohr geführte Verbindung dieser Schmierleitung erspart wird, während der Vorteil erhalten bleibt, daß das frische Fett von innen in die Schmierstelle eingedrückt wird und dabei das verbrauchte Fett aus den Schmierstellen herausdrückt.The invention relates to a lubricating device for bicycles and the like Vehicles and consists essentially in the fact that the pressure grease lubrication for a or several lubrication points on the wheel at or near these lubrication points attached nipples is done; this applies in particular to the steering head and the bottom bracket, their separate lubrication has the advantage that the guided through the down tube Connection of this lubrication line is spared, while the advantage is retained, that the fresh grease is pressed into the lubrication point from the inside and that pushes used grease out of the lubrication points.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. i einen Rahmen mit getrennter Steuerkopf-und Tretlagerschmierung, Fig. z und 3 verschiedene Ausführungen der Tretlagerschmierung.An exemplary embodiment of the invention is shown in the drawing. It shows Fig. I a frame with separate control head and bottom bracket lubrication, Fig. Z and 3 different versions of the bottom bracket lubrication.

Nach der Erfindung sind der Steuerkopf und das Tretlager für sich schmierbar, so daß das im Unterrohr verlegte Verbindungsrohr erspart wird. Zu diesem Zweck ist ein besonderes nach außen geführtes Schmierröhrchen in. vorgesehen, das in das Abstandsrohr f mündet, während es außen mit dem Nippel c versehen ist.According to the invention, the control head and the bottom bracket are in themselves can be lubricated, so that the connecting tube laid in the down tube is saved. To this Purpose is a special outwardly guided lubrication tube in. Provided that opens into the spacer tube f, while it is provided with the nipple c on the outside.

Wie die Ausführungsbeispiele der Fig. a und 3 zeigen, mündet dieser Schmiernippel in, c in der Mitte des Abstandsrohres f ; er kann aber auch außerhalb der Mitte des Abstandsrohres f münden (Fig. a, gestrichelte Ausführung).As the embodiments of FIGS. A and 3 show, this lubricating nipple opens into, c in the middle of the spacer tube f; but it can also open out outside the center of the spacer tube f (FIG. a, dashed design).

Bei dem Ausführungsbeispiel der Fig. 3 ist auch das Abstandsrohr f gespart und dafür der die Tretlagerachse la umgebende Raum sa geschlossen ausgebildet und ganz mit-Fett gefüllt und der Schmiernippel an diesen Raum angeschlossen, so daß er jederzeit nachgefüllt werden kann.In the embodiment of FIG. 3, the spacer tube f saved and instead the space sa surrounding the bottom bracket axle la is designed to be closed and completely filled with grease and the grease nipple connected to this space, like that that it can be refilled at any time.
