Description
Doppeldrehgelenk für Tragarme elektrischer Leuchten Der Erfindungsgegenstand ist ein neues Doppeldrehgelenk für elektrische Leuchten, insbesondere Wandarme. Die bekannten Gelenke dieser Art haben den Nachteil, daß die Litze überhaupt nicht durchführbar odermehr oder weniger bei der Durchführung durch die Bewegung des Gelenkes gefährdet ist. Diesen Fehler schließt das neue Gelenk vollständig aus.Double swivel joint for support arms of electric lights The subject of the invention is a new double swivel joint for electric lights, especially wall arms. The known joints of this type have the disadvantage that the braid is not at all feasible or more or less when performed by moving the joint endangered is. The new joint completely eliminates this error.
Die Neuerung besteht hauptsächlich darin, daß die Bremsschraube der vertikalen Bewegung nicht vor der Rohrmitte des Tragarmes, sondern exzentrisch liegt, so d'aß die Litze frei über das Drehmittel gehen kann und dadurch sowie infolge einer Aussparung des Mittelstückes keinerlei Bewegung bei Vertikalschwenkung des Armes ausgesetzt ist, während das Mittelstück mit seitlichen Ansätzen in schalenartigen Vertiefungen zweier an sich bekannter Seitenstücke gelagert ist. Weiter bieten die als Horizontallagerung für die Seitenstücke dienenden, axial durchbohrten Angeln durch ihren Zwischenabstand freien Raum zur zwanglosen Durchführung der Litze. Es ist dadurch auch möglich, die Litze nach unten oder oben auszuführen.The main innovation is that the brake screw of the vertical movement is not in front of the pipe center of the support arm, but eccentrically, so that the strand can go freely over the rotating means and thereby and as a result a recess in the middle piece no movement when pivoting the vertical Arm is exposed, while the middle piece with lateral approaches in cup-like Wells of two known side pieces is mounted. The serving as a horizontal bearing for the side pieces, axially pierced hinges Due to their spacing between them, there is free space for the unconstrained passage of the braid. It this also makes it possible to run the strand downwards or upwards.
In Abb. i und 2 ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform dargestellt. Abb. i ist eine Seitenansicht, Abb.2 Draufsicht, teilweise geschnitten.In Fig. I and 2 the subject of the invention is in an exemplary manner Embodiment shown. Fig. I is a side view, Fig. 2 is a plan view, partially cut.
Das mit einer Aussparung versehene Mittelstück lt wird auf seinen seitlichen Ansätzen in der schalenförmigen Vertiefung s der Seitenstücke a zentrisch schwenkbar gelagert. Die Seitenstücke werden durch die exzentrisch liegende Schraube f o. d'gl. bremsend zusammengehalten. Die zentrale Bohrung r ist so groß, daß bei Bewegung des Mittelstückes k die exzentrisch liegende Schraube f ohne Berührung umkreist wird. Die Seitenstücke a umfassen anderseits die beiden Angeln e und ei, in Abb. i und 2 beispielsweise am Bügel! befestigt, und werden durch die Schrauben g und g1 bremsend zusammengehalten, wodurch die Drehbewegung möglich ist. Die beiden Seitenstücke sind außerdem unten und oben mit einem Lappen h versehen, welcher als Anschlag dient.The center piece lt, which is provided with a recess, is mounted on its lateral attachments in the bowl-shaped recess s of the side pieces a so that it can pivot centrally. The side pieces are by the eccentric screw f o. D'gl. held together braking. The central bore r is so large that when the center piece k moves, the eccentric screw f is circled without contact. On the other hand, the side pieces a comprise the two hinges e and ei, in Fig. I and 2 for example on the bracket ! fastened, and are held together by the screws g and g1 braking, whereby the rotary movement is possible. The two side pieces are also provided with a tab h at the bottom and top, which serves as a stop.
