Description

Haltanzeiger für Fahrräder Die Erfindung betrifft eine Schaltvorrichtung für einen Haltanzeiger für Fahrräder, bei dem bei Betätigung der Bremse eine elektrische Lampe zum Aufleuchten gebracht wird. Im Gegensatz zu den bekannten Einrichtungen wird hierbei die Reibung zwischen einer um die Tretkurbelachse eines Fahrrades gelegten Feder und der Achse benutzt, um den Kontakt des Haltanzeigers zu öffnen und zu schließen.Stop indicators for bicycles The invention relates to a switching device for a stop indicator for bicycles, in which when the brake is actuated an electric Lamp is made to light up. In contrast to the well-known facilities is here the friction between a placed around the crank axle of a bicycle Spring and the axis are used to open and close the contact of the stop indicator.

Die Zeichnung veranschaulicht den Erfindungsgegenstand, und zwar zeigt Abb. i denselben in Draufsicht von vorn, teilweise im Schnitt und mit offenen Kontakten, Abb.2 denselben mit geschlossenen Kontakten, Abb. 3 einen Schnitt A-B.The drawing illustrates the subject matter of the invention, namely shows Fig. I the same in top view from the front, partly in section and with open contacts, Fig.2 the same with closed contacts, Fig. 3 a section A-B.

In einer nutartigen Eindrehung ist um die Tretkurbelachse a die Feder b gelegt, so daß sie die Achse fast ganz umschließt. Das eine Federende ist zu einem Arm c ausgebildet, welcher in das Sattelrohr d hineinragt. In demselben ist ein elektrischer Kontakt, bestehend aus den Teilen e und f, untergebracht. Werden die Pedale vorwärts getreten, d. h. in Richtung des Pfeiles g, so nimmt der Arm c die Stellung in Abb. i, beim Rückwärtstreten der Pedale, d. h. in Richtung des Pfeiles h, die Lage in Abb. 2 ein. In letzterer drückt der Arm c die Kontakte e und f aneinander und schließt über i und k den Stromkreis einer in bekannter Weise am hinteren Ende des Fahrrades angebrachten, als Haltanzeiger dienenden Glühlampe.In a groove-like recess , the spring b is placed around the pedal crank axis a so that it almost completely encloses the axis. One end of the spring is formed into an arm c which protrudes into the seat tube d. An electrical contact consisting of parts e and f is housed in the same. If the pedals are stepped forward, ie in the direction of the arrow g, then the arm c assumes the position in Fig. I, when the pedals are stepped backwards, ie in the direction of the arrow h, the position in Fig. 2. In the latter, the arm c presses the contacts e and f together and closes the circuit via i and k of an incandescent lamp which is attached in a known manner to the rear end of the bicycle and serves as a stop indicator.
