Description

Im Fahrradrahmenbau geht man immer mehr dazu über, an Stelle von ovalen kreisrunde Gabelstreben zu verwenden. An Sportfahrrädern ist die 'Verwendung von kreisrunden, sehr dünnen Streben, die sich zum Gabelschuh hin noch verjüngen, besonders zu beobachten. Einige Fahrradfabriken bringen bereits gewöhnliche Gebrauchsfahrräder mit kreisrunden bzw. wenig ovalgeformten Gabelstreben auf den Markt.In bicycle frame construction, there is more and more being used instead of oval ones use circular fork struts. The use of circular, very thin struts that taper towards the fork shoe, especially to observe. Some bicycle factories already bring ordinary utility bicycles with circular or slightly oval shaped fork struts on the market.

Solange das Fahrrad stark ovalgeformte Streben besaß, erhielt das angeschraubte Schloß einen festen, unverrückbaren Sitz. Das Unrundsein der Strebe gab keinem Dieb die Möglichkeit, daß Schloß auf der Gabelstrebe seitlich zu verdrehen.As long as the bike had strong oval-shaped struts, the screwed lock a firm, immovable seat. The out-of-roundness of the strut did not give a thief the opportunity to twist the lock sideways on the fork strut.

Anders ist es heute. Auf kreisrund- bis wenig ovalgeformten Streben findet ein Speichenschloß an dem bekannten Ort der Anbringung keinen Halt mehr, auch wenn die Befestigungsschrauben noch so fest angezogen wurden. Es stellt sich daher die Frage: Wo und wie kann auf kreisrunder oder wenig ovalgeformter Strebe ein Speichenschloß unverrückbar fest angebracht werden. Eine geeignete Lösung bringt die Erfindung, derzufolge das Schloß auf dem unteren Ende der Gabelstrebe über a-b nach der Zeichnung zu sitzen kommt. Die Befestigungsschelle des Schlosses ist so geformt, daß sie nach oben hin die kreisrunde Strebe a, nach unten hin einen Teil des anschließenden, flachgepreßten Gabelschuhes b umschließt. Durch die eng anliegende Umschließung des flachen Teiles b wird das Schloß gegen ein seitliches Verdrehen gesichert.It is different today. On circular to slightly oval shaped struts a spoke lock no longer finds a hold at the known place of attachment, no matter how tight the fastening screws were. It turns out Hence the question: where and how can a circular or slightly oval strut be used a spoke lock can be attached immovably. Bringing a suitable solution the invention, according to which the lock on the lower end of the fork strut via a-b after the drawing comes to sit. The fastening clamp of the lock is like this shaped that they upwards the circular strut a, downwards a part of the subsequent, flat-pressed fork shoe b encloses. Due to the tight-fitting Enclosing the flat part b will prevent the lock from twisting sideways secured.
