Description
keibungskupplung für Kabelroller elektrischer Lampen. Kabelroller mit Reibungskupplung und Sperrad, bei denen die Stromzuleitung durch die hohle Achse erfolgt, sind bekannt. Man macht solche Kabelroller, insbesondere Bremskupplungen, zwecks Herabminderung der Kosten häufig aus Holz. Wenn Holz sich auch gerade als Bremsmittel besonders gut, eignet, so weisen doch die bekannten H'olzkabelroller häufig den Nachteil auf, daß die Bremswirkung nicht sanft, sondern ruckweise erfolgt. Diesem übelstand begegnet die Erfindung.Kibungskupplung for cable reels for electric lamps. Cable reel with friction clutch and ratchet wheel, in which the power supply line through the hollow axis are known. One makes such cable reels, especially brake clutches, often made of wood to reduce costs. If wood turns out to be Braking means particularly good, is suitable, as the known wooden cable reels have often the disadvantage that the braking effect is not gentle, but jerky. The invention counteracts this deficiency.
Die Abbildung zeigt eine Ausführungsform des neuen Kabelrollers, wobei mit i und z die übliche Kabeltrommel und mit 4 die radial um die Achse durch die Feder 6 zusammengedrückten Keilstücke bezeichnet sind. i o ist das lose auf der Trommel angeordnete Sperrad, das in Reibungseingriff mit den Keilstücken 4 steht. 5 sind Stahlkugeln, auf die sich die Keilstücke 4 aufsetzen, so daß sie in ihrer Bewegung nach der Achsmitte zu begrenzt werden. Dadurch wird ein gleichmäßiger Auflagedruck der einzelnen Keilstücke gewährleistet und eine sanfte Bremswirkung erzielt, weil eine Verschiebung der Keilstücke 4 durch den Druck der Feder 6 oder durch das sich drehende Sperrad io nicht erfolgen kann.The figure shows an embodiment of the new cable reel, wherein with i and z the usual cable drum and with 4 the radial around the axis through the Spring 6 compressed wedge pieces are designated. i o that's loose on the Ratchet wheel arranged on the drum, which is in frictional engagement with the wedge pieces 4. 5 are steel balls on which the wedge pieces 4 sit so that they are in their Movement after the axis center is too limited. This creates an even contact pressure of the individual wedge pieces guaranteed and achieved a gentle braking effect because a displacement of the wedge pieces 4 by the pressure of the spring 6 or by itself rotating ratchet wheel io cannot be done.
