Description
Gelenk für Lampenfüße und Pendelleuchten Das vorliegende Kugelgelenk unterscheidet sich von den bereits bekannten Gelenken dieser Art durch ein in sich starres Zwischenstück. das zwischen dem Kugelabschnitt und der mit der Kugelschale fest verbundenen Grundplatte eingespannt ist. Die Enden dieses Zwischenstückes sind kugelig oder spitz ausgeführt. Sie ragen in entsprechende Ausnehmungen " vorn Grundplatte und Kuge'.abschnitt hinein, so daß das Zwischenstück festgelegt ist, aber infolge seiner kugeligen oder spitzen Auflager trotzdem .eine Bewegung des Kugelabschnitts gestattet. Wichtig ist, daß die untere, in der Grundplatte befindliche Lagerstelle des Zwischenstückes unterhalb des Mittelpunktes der Gelenkkugel sich befindet. Dadurch tritt bei Drehung des Gelenks aus der Mittelstellung heraus eine geringe, allmählich zunehmende. Verkürzung des Abstandes der beiden Lagerpunkte des Zwischenstückes ein. Letzteres läßt jedoch infolge seiner Starrheit diese Verringerung nicht zu, und deshalb preßt sich der Kugelabschnitt in seiner Kugelschale fest.Joint for lamp bases and pendant lights The present ball joint differs from the already known joints of this type by one in itself rigid intermediate piece. that between the spherical section and the one with the spherical shell firmly connected base plate is clamped. The ends of this adapter are spherical or pointed. They protrude into corresponding recesses "in front of the base plate and Kuge'.abschnitt in, so that the intermediate piece is fixed, but as a result its spherical or pointed supports nevertheless. a movement of the spherical section allowed. It is important that the lower bearing point located in the base plate of the intermediate piece is located below the center point of the joint ball. Through this When the joint is rotated from the central position, there is a slight, gradual effect increasing. Shortening the distance between the two bearing points of the intermediate piece a. However, the latter does not allow this reduction due to its rigidity, and therefore the ball section presses itself firmly in its ball socket.
Da diese Festklemmung bei senkrechter Stellung des Lampenarmes oder Pendelrohrs am geringsten ist und am stärksten bei seitlich herausgeschwenkter Stellung dieser Tragorgane, kommt sie den Forderungen. der Praxis in günstiger Weise entgegen.Since this jamming when the lamp arm is in a vertical position or Pendulum tube is smallest and strongest when swung out to the side of these supporting organs, it comes to the demands. contrary to practice in a favorable manner.
Die Bremsung kann auch weicher und gleichmäßiger gemacht werden, wenn die Grundplatte des Gelenks als Plattenfeder ausgebildet wird. Diese gestattet ein Ausweichen des Zwischenstückes nach unten und mildert dadurch den Bremsdruck.The braking can also be made smoother and smoother, though the base plate of the joint is designed as a plate spring. This allows one Evasion of the intermediate piece downwards and thereby relieves the brake pressure.
Bei einem einfachen, scharnierartigen Gelenk tritt an Stelle des Kugelabschnitts ein; Kreisscheibenabschnitt mit entsprechender Führung.In the case of a simple, hinge-like joint, the spherical section is used instead a; Disc section with appropriate guidance.
Die Zeichnung zeigt an zwei Beispielen das Wesen der Erfindung im Schnitt, und zwar ist aus Abb. i ein Gelenk mit starrer Grundplatte ersichtlich, während Abb. a ein solches mit Plattenfeder darstellt.The drawing shows the essence of the invention in two examples Section, namely a joint with a rigid base plate can be seen from Fig. while Fig. a shows one with a diaphragm.
Der Kugelabschnitt a, der zweckmäßig nicht aus einer vollen Halbkugel besteht, wird umfaßt von der zu ihm passenden Kugelschaleb, die wieder mit .der Grundplatte c fest verschraubt ist. Die Länge des Zwischenstückes ,d ist so bemessen, daß ihr unterer Lagerpunkt e, der .durch Stellschraube f verstellt werden kann, unterhalb des Kugelmittelpunkts g liegt. Bei Seitwärtsschwenkung des Lampenarmes, etwa in die punktierte Stellung, erfährt der Abstand zwischen den Lagerpunkten e und h eine geringe Verkürzung, wodurch der erhöhte Bremsdruck hervorgerufen wird.The spherical section a, which does not consist of a full hemisphere, is encompassed by the spherical shell that matches it, which is again firmly screwed to the base plate c. The length of the intermediate piece, d is dimensioned so that its lower bearing point e, which can be adjusted by adjusting screw f, lies below the center point g of the sphere. When the lamp arm is pivoted sideways, for example into the dotted position, the distance between the bearing points e and h experiences a slight shortening, which causes the increased braking pressure.
Bei der Ausführung nach Abb. i tritt an Stelle der starren Grundplatte eine kreiuy förmige, ringsum fest eingespannte Plattenfeder i, die in der Mitte die Nachstellschraube (trägt.In the design according to Fig. I, the rigid base plate is used a kreiuy-shaped plate spring i firmly clamped all around, the one in the middle the adjuster screw (carries.
