Description

Reibungstrommel für elektrische Stehlampen mit drehbarem Träger. Die vorliegende Erfindung betrifft die einfache Ausführung einer Reibungstrommel in Stehlampen rriit drehbarem Träger und ähnlichen Beleuchtungskörpern. Werden derartige Reibungstrommeln, deren Verwendung z. B. in Fig. 3 dargestellt ist, aus Gußeisen angefertigt, so müssen diese Teile auf der Drehbank bearbeitet werden. Gemäß vorliegender Erfindung wird die Reibungstrommel aus Druck- oder Stanzstücken hergestellt und durch eine besondere Anordnung trotz der Verwendung von Blechen eine genügende Festigkeit gewährleistet, welche derjenigen eines massiven Metallkörpers nicht nachsteht. Zwei Kapseln von entsprechendem Durchmesser, die durch Stanzen, Drücken oder Ziehen hergestellt sind, werden ineinandergeschoben. Diese beiden zylindrischen Kapseln haben in ihrer zylindrischen, Wandung j e eine Bohrung zur späteren Aufnahme des Trägerrohres und eine rechteckige Öffnung zur Herausführung der Leitung. Durch Umbiegen der Lappen a können die beiden Kapseln, gegen seitliche Verdrehung gesichert werden. Das Trägerrohr kann in einfacher Weise dadurch befestigt werden, daß die Achse .der entstehenden Trommel durch dieses Rohr hindurchgeführt wird. Die Fig. 2 zeigt die Reibungstrommel nach dem Zusammenfügen, die Fig. 3 ihren Einbau in_ einen Lampenfuß. Die Achse der Trommel a geht gleichzeitig durch das Lampenrohr b, welches durch den kreisförmigen Ausschnitt c durch die Trommel tritt. Die Leitung, die durch das Rohr b hinuntergeführt wird, kann durch den Ausschnitt in der Trommel d-e herausgeführt werden.Friction drum for electric floor lamps with rotatable support. the The present invention relates to the simple design of a friction drum in Floor lamps with rotatable supports and similar lighting fixtures. Will such Friction drums whose use z. B. shown in Fig. 3, made of cast iron made, these parts must be machined on the lathe. According to the present Invention, the friction drum is made from printed or stamped pieces and Due to a special arrangement, despite the use of metal sheets, sufficient strength guaranteed, which is not inferior to that of a solid metal body. Two Capsules of appropriate diameter made by punching, pressing or drawing are pushed together. These two cylindrical capsules have in their cylindrical, wall j e a bore for later receiving the support tube and a rectangular opening for leading out the cable. By bending over the tabs a, the two capsules can be secured against lateral rotation. The carrier tube can be attached in a simple manner that the axis .der emerging Drum is passed through this tube. Fig. 2 shows the friction drum after assembly, FIG. 3 shows its installation in a lamp base. The axis of the Drum a also goes through the lamp tube b, which is through the circular Section c passes through the drum. The line that passed down through the pipe b can be led out through the cutout in the drum d-e.
