Elektrische Rohrzugpendel mit von der Lampe aus auslösbarem Klemmgesperre sind bereits bekannt. Die vorliegende Erfindung betrifft eine besondere Zusammenstellung zum Teil bekannter Teile, welche eine sichere und leicht lösbare Sperrung gewährleistet.Electric tube pull pendulums with clamping locks that can be triggered by the lamp already known. The present invention relates to a particular combination for Part of known parts, which ensures a safe and easily releasable lock.
Die Zeichnung zeigt das Pendel in Ansicht und Schnitt.The drawing shows the pendulum in elevation and section.
Das Rohrzugpendel besteht aus dem Außenrohr α, dem Rohr b und dem Auszugsrohr c. Das Rohr b ist oben konisch gestaltet und unten mit der Glühlampenfassung und der Armatur fest verbunden.' Zwischen Rohr b und c ist die Feder d angeordnet. Sie bewirkt, daß das Auszugsrohr c, welches oben geschlitzt ist, zwischen Außenrohr α und Konus k festgeklemmt wird. Die Lösung der Klemmung erfolgt durch Zusammendrücken der Feder d mittels der Bügel e und »,wobei der Bügel / mit der Armatur bzw. der Fassung fest verbunden ist. Das Außenrohr a hat auf dem oberen Ende ein Isoliergehänge mit Baldachin und unten eine Überwurfsmutter h, die die Führung des Rohres c bezweckt.The tube pull pendulum consists of the outer tube α, the tube b and the extension tube c. The tube b has a conical shape at the top and is firmly connected at the bottom to the bulb socket and the fitting. ' The spring d is arranged between tube b and c. It has the effect that the extension tube c, which is slotted at the top, is clamped between the outer tube α and the cone k. The clamping is released by compressing the spring d by means of the brackets e and », the bracket / being firmly connected to the fitting or the socket. The outer tube a has an insulating hanger with a canopy on the upper end and a union nut h at the bottom, which is used to guide the tube c .
Die Stromzuführungslitze g ist schraubenförmig aufgewickelt und dadurch befähigt, den Auszugsbewegungen zu folgen. Das Rohr c ist auf dem oberen Ende geschlitzt und mit Löchern versehen, in welche Stahlkugeln eingelegt sind. ■■-...._The power supply cord g is wound up in a helical manner and is thus able to follow the pull-out movements. The tube c is slotted on the upper end and provided with holes in which steel balls are inserted. ■■ -...._
