KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den bekannten Pendelaufzügen für Lampen mit zylindrischer Federtrommel ist das Drehmoment bei jeder beliebigen Stellung der Lampe nicht gleich. Nach vorliegender Erfindung wird das Drehmoment dadurch gleichgemacht, daß eine konische Seil- oder Federtrommel verwendet wird. Konische Trommeln sind zur Erzielung eines stets gleichen Drehmomentes bereits bei Uhren undIn the known shuttle lifts for lamps with a cylindrical spring drum the torque is not the same for any position of the lamp. According to the present Invention, the torque is made equal in that a conical rope or Spring drum is used. Conical drums are already used in watches and to achieve a constant torque

ίο bei Bergwerksaufzügen benutzt worden. Die Erfindung besteht also in der Übertragung dieser bekannten Einrichtung auf Lampenaufzüge. ' ίο has been used on mine elevators. The invention therefore consists in transferring this known device to lamp lifts. '

Auf der Zeichnung ist als ein Ausführungsbeispiel ein Pendelaufzug nach vorliegender Erfindung dargestellt, welcher zur Aufhängung einer elektrischen Lampe dienen soll.In the drawing, a pendulum elevator according to the present invention is shown as an exemplary embodiment Invention shown, which is intended to be used to suspend an electric lamp.

Der Aufzug ist mit einer zur Befestigung an der Decke dienenden Schale oder Rosette a versehen, welche ein trommeiförmiges Gehäuse b trägt. Dasselbe wird seitlich durch zwei Deckel c und d verschlossen, durch deren Mitten zwei in den Scheiben 0 und ρ gelagerte Achsen e und f geführt sind, die in einer Geraden liegen. .The elevator is provided with a shell or rosette a which is used for fastening to the ceiling and which carries a drum-shaped housing b. The same is closed laterally by two covers c and d , through the middle of which two axes e and f, which are supported in the disks 0 and ρ and lie in a straight line, are guided. .

Auf den Achsen ist eine konische Seiltrommel s angeordnet, die eine schneckenförmig gewundene Nut besitzt, auf welche das Aufhängekabel t gewickelt ist, welches das Ausgleichgewicht \ trägt. In der^ Seiltrommel ist ein FederhaUs 4 untergebracht, welches eine Uhrfeder 5 . umschließt, deren eines Ende in den an der Achse f sitzenden Haken 6 eingehakt ist, während das andere , Ende an dem Stift 7 sitzt.On the axes of a conical cable drum is arranged s, which has a helical winding groove to which the suspension cable is wound t carrying the balance weight \. A spring housing 4 is housed in the cable drum, which has a clock spring 5. one end of which is hooked into the hook 6 seated on the axis f , while the other end is seated on the pin 7.

Claims (1)

Patent-Anspruch:Patent claim: Pendelaufzug für Lampen mit einer das Aufhängekabel tragenden Seiltrommel und einer der Abwickelung des Kabels entgegenwirkenden Feder, dadurch gekennzeichnet, daß die Seiltrommel (s) konisch gestaltet ist, zum Zweck, bei jeder Stellung der Lampe ein gleiches Drehmoment der Trommel zu erhalten.Pendulum lift for lamps with a cable drum carrying the suspension cable and a spring counteracting the unwinding of the cable, characterized in that the cable drum (s) is conical in shape, for the purpose of obtaining the same torque of the drum in every position of the lamp.
