Abstract

Ball joints for submarine flash light arms comprises friction lining with spherical or conical recesses for joint clamps.

Description

Gegenstand der Erfindung sind Kugelgelenke mit Reibbelägen für Unterwasser Blitzarme.The invention relates to ball joints with friction linings for Underwater lightning arms.

Bei Unterwasser Fotogeräten werden häufig Kugelgelenkarme verwendet, um Unterwasser Blitzgeräte und Zubehör am Kameragehäuse zu befestigen. Kugel­ gelenkarme mit rasch lösbaren Klemmverbindungen verwendet man deshalb, um das Blitzgerät schnell in verschiedenen Positionen zum Fotogerät fixieren zu können. Positionsveränderungen müssen rasch, ohne besondere Kraftanstrengung und ohne Werkzeug vorgenommen werden können. Während die eingestellte Position wegen des geringeren Gewichtes unter Wasser noch verhältnismäßig leicht zu halten ist, ist dies vor und nach dem Tauchgang über Wasser wesentlich schwieriger.Underwater photo machines often use ball joint arms to Underwater flash units and accessories to attach to the camera body. ball articulated arms with quick release clamp connections are therefore used to Quickly fix the flash in different positions to the camera can. Position changes must be quick, without any special effort and can be done without tools. While the set position because of the lower weight under water still relatively easy to This is essential before and after the dive over water difficult.

Herkömmliche Kugelgelenk Blitzarme sind aber kaum in der Lage, ein mehrere Kilogramm schweres Blitzgerät auch über Wasser in Position zu halten.Conventional ball-and-socket flash arms are barely able to hold one more Kilogram heavy flash unit even in position above water.

In Fig. 1 und 2 sind zwei Versionen solcher Kugelgelenke für Unterwasser Blitz­ arme dargestellt, Kernstück der Gelenke sind die Gelenkkugeln 1 und die Klemmteile 2. Eine Fixierung der Verbindungsarme 4 und 5 erreicht man durch Festziehen der Klemmschraube 3. Durch Lösen der Klemmschraube 3 erreicht man ein Lockern der Klemmteile 2 für eine Neupositionierung des Blitzgerätes zum Fotogerät.In Fig. 1 and 2, two versions of such ball joints for underwater lightning are shown poor, the core of the joints are the joint balls 1 and the clamping parts. 2 A fixation of the connecting arms 4 and 5 can be achieved by tightening the clamping screw. 3 By loosening the clamping screw 3 to reach a loosening of the clamping parts 2 for repositioning the flash unit to the photo set.

Um eine möglichst große Klemmwirkung und somit Haltekraft der Verbindungsarme zu erreichen, wurden verschiedene Materialpaarungen verwendet.To the greatest possible clamping effect and thus holding force of the connecting arms To achieve different material pairings were used.

All die angeführten Materialpaarungen und auch noch weitere, ergaben nicht die gewünschte Haltekraft für die Verbindungsarme 4 und 5.All the listed material pairings and even more, did not give the desired holding force for the connecting arms 4 and 5 .

Diesem Schwachpunkt der bisher bekannten Kugelgelenkarme für die Unterwasser Fotografie, wird durch die gegenständliche Erfindung wirkungsvoll abgeholfen.This weakness of the previously known ball joint arms for the underwater Photography, is effectively remedied by the subject invention.

Um eine hohe Haltekraft für die Verbindungsarme 4 und 5 zu erreichen, werden bei Verwendung von Gelenkkugeln 1 aus Stahl, Leichtmetall oder Kunststoff, Klemmteile 2 aus Stahl, Leichtmetall oder Kunststoff verwendet, bei denen Reibscheiben 6 aus bekanntem Reibbelag (Brems- oder Kupplungsbeläge) einge­ setzt sind. Eine weitere Lösung besteht darin, den Reibbelag nicht an den Klemmteilen 2, sondern an den Gelenkkugeln 1 anzubringen. Dazu werden die Gelenkkugeln 1 mit Reibbelag überzogen, oder aus Reibbelag hergestellt. Mit Hilfe dieser Reibbeläge an den Klemmteilen 2 oder Gelenkkugeln 1, wird eine mehrfache Haltekraft gegenüber bisher bekannten Blitzarmen mit Kugelgelenken erreicht. Die Form der Reibscheiben 6 ist zylindrisch, mit einer kugel- oder kegelförmigen Ausnehmung an einer Seite, in welcher die Gelenkkugel 1 durch Festklemmen gehalten wird. In order to achieve a high holding force for the connecting arms 4 and 5 , when using ball bearings 1 made of steel, light metal or plastic, clamping parts 2 made of steel, light metal or plastic used in which friction discs 6 from known friction lining (brake or clutch linings) turned are set. Another solution is not to attach the friction lining to the clamping parts 2 , but to the joint balls 1 . For this purpose, the joint balls 1 are coated with friction lining, or made of friction lining. With the help of these friction linings on the clamping parts 2 or joint balls 1 , a multiple holding force over previously known flash arms is achieved with ball joints. The shape of the friction plates 6 is cylindrical, with a spherical or conical recess on one side, in which the joint ball 1 is held by clamping.

Die Vorteile von Kugelgelenken mit Reibbelägen für Unterwasser Blitzarme sind folgende:The advantages of ball joints with friction linings for underwater flash arms are the following:

  • 1) Wesentlich erhöhte Haltekraft (2-3fach) der Kugelgelenke gegenüber bisher bekannten Kugelgelenken an Blitzarmen für Unterwasser Fotografie.1) Significantly increased holding force (2-3 times) of the ball joints compared to previously known ball joints on lightning arms for underwater photography.
  • 2) Hohe Haltekraft bei geringer Klemmkraft und daher leichte Bedienung der Klemmschrauben.2) High holding power with low clamping force and therefore easy operation of Clamping screws.
  • 3) Geschmeidige Verstellungsmöglichkeit der Kugelgelenke durch die besondere Eigenart von Reibbelägen.3) Smooth adjustment of the ball joints by the special Characteristic of friction linings.
  • 4) Möglichkeit der festen Positionierung, auch von schweren Blitzgeräten über und unter Wasser.4) possibility of fixed positioning, even from heavy flash units over and under water.
