Description
Zum Anziehen der Nabenachsmutter bei Fahrrädern dienender Handhebel. Es ist neuerdings .gebräuchlich, bei Fahrrädern, namentlich solchen für Rennzwecke, zwecks rascher Auswechslungsmöglichkeit der Räder, zur Befestigung Hebelmuttern, d. h. solche mit Griffen, zu verwenden, die den Gebrauch. besonderer Schraubenschlüssel überflüssig machen. Es ist ferner bekannt, Mutter und Hebel :getrennt auszuführen, und durch eine Kupplung einstellbar miteinan,-der zu verbinden. Gemäß der Erfindung ist der Hebel als Schraubenschlüssel ausgebildet, dessen die Mutter umfassendes Maul an, der einen Seite durch eine mit einer Bohrung für die Nabenachse versehene tWand verschlossen ist, die zwischen der Rahmengabel und der Mutter durch letztere festgeklemmt wird.Hand lever used to tighten the hub axle nut on bicycles. It has recently been used on bicycles, especially those for racing purposes, for the purpose of quick replacement of the wheels, for fastening lever nuts, d. H. those with handles, to use that the use. special wrench make superfluous. It is also known to perform nut and lever separately, and adjustable with one another by means of a coupling. According to the invention the lever is designed as a wrench, which includes the nut Maul, one side through a provided with a hole for the hub axle The wall is closed between the frame fork and the nut by the latter is clamped.
Die Zeichnung veranschaulicht eine Ausführwngsform der Erfindubg in Abb. i in Seitenansicht mit teilweisem Längsschnitt nach der Linie kA der Abh. a, die die Aufsicht zeigt.The drawing illustrates one embodiment of the invention in FIG Fig. I in side view with partial longitudinal section along the line kA of Abh. A, which shows the supervision.
Der Schraubenschlüssel 3 kann finit offenem oder geschlossenem Maul ausgeführt werden und hat einen zweckmäßig geformten und gerichteten Hebel q.. Um den Schlüssel gegen Herabfallen von der Nabenachse zu sichern, ist das Maul 3 auf der einen Seite mit einer Wand verschlossen, in der eine Bohrung zum Aufstecken auf die Achse a vorgesiehen ist. Bei dieser Anordnung ersetzt die Wand die sonst nötige Unterlegscheibe und. verleiht dem S.c'hlüssehnau13 eine erhöhte Festigkeit, die wiederum ,eine für diese Zwecke wün, achenswerte leichtere Ausführung ermöglicht.The wrench 3 can have a finite open or closed mouth be executed and has a suitably shaped and directed lever q .. To To secure the key against falling off the hub axle, the mouth 3 is open one side closed with a wall, in which a hole for plugging on is provided on the axis a. With this arrangement, the wall replaces the usual one necessary washer and. gives the S.c'hlüssehnau13 increased strength, which in turn enables a lighter design that is desirable for these purposes.
Die Anwendung des Schlüssels geschieht in der aus Abb. i ersichtlichen Weise. D;ex Schlüssel 3 wird zunächst auf die Nabenachse z gesteckt und dicht .an die Rahmengabel .geschoben. Hierauf wird: @die Bafestigungsmutter i aufges.chraubt, was bis .nahe zum Schlüssel 3 geschehen kann, der alsdann über die Mutter i geschoben wird, um das Anziehen derselben zu vollenden. Hierbei wird die Wand des Schlüssels zwischen Rahmengabel und Mutter festgeklemmt. Die für -die Fahrt vorteilhafteste Stellung des Hebels- ¢, die nach rückwärts .gerichtete, kann infolge der sechsfachen Umsteckmöglichkeit nach etwaigem versuchsweisen Anziehen der Mutter i leicht herbeigeführt werden.The key is used as shown in Fig. I Way. D; ex key 3 is first placed on the hub axis z and tightly the frame fork. Then: @ the fastening nut i is screwed on, what can happen up to .near to the key 3, which is then pushed over the mother i to complete the tightening of the same. This becomes the wall of the key stuck between frame fork and nut. The most advantageous for the journey Position of the lever - ¢, the backwards Possibility to change the position after any attempted tightening of the nut i easily brought about will.
