Description
Federnde, wasserdichte Aufhängevorrichtung für elektrische Glühlampen o. dgl. Um ciie schädliche Einwirkung von Erschütterungen, wie solche hauptsächlich in indL,str=ellen Betrieben vorkommen, auf die empiindlichen Glühfäden -elektrischer Glühlampen !u verhindern, hat man die Glühlampen federnd aufgehängt. Ebenso ist es bekannt und gebräuchlich, die Armatur für aufgehängte Lampen mit einem unter Federwirkung stehenden Kugelgelenk zu versehen, um die Lampen nach verschiedenen Seiten hin bewegen und einstellen zu können.Spring-loaded, waterproof suspension device for electric light bulbs or the like. To ciie the harmful effects of vibrations, such as those mainly occur in indL, str = ellen companies, on the sensitive filaments -electric To prevent incandescent lamps, the incandescent lamps have been suspended. Likewise is it is known and common, the fitting for suspended lamps with an under Spring action to provide standing ball joint to the lamps according to different Moving and adjusting pages.
Die vorliegende Erfindung besteht in der Komb?nation eines unter Federwirkung stehenden, abgedichteten Kugelgelenkes mit einer federndenAufhängevorrichtungfür elektrische Glühlampen, wodurch die nach verschiedenen Seiten hin drehbaren und einstellbaren Lampen gleichzeitig vor den schädlichen Einwirkungen der Erschütterungen geschützt sind und die im Kugelgelenk befindliche Zuleitung cler Lampe stets dicht abgeschlossen ist.The present invention consists in the combination of a spring action standing, sealed ball joint with a resilient suspension device for electric light bulbs, whereby the rotatable in different directions and adjustable lamps at the same time from the harmful effects of the vibrations are protected and the supply line of the lamp located in the ball joint is always tight is completed.
Auf der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform beispielsweise im Längsschnitt veranschaulicht.The subject of the invention is shown in one embodiment in the drawing illustrated for example in longitudinal section.
Der Gegenstand der Erfindung besteht aus einem rohrförmigen Aufhänger a, welcher in einer Hülse b geführt wird. Das Rohr a ist mit Gewinde ä zum Anbringen der Lampen einerseits versehen und besitzt andererseits einen umgebördelten Rand ä', der sich auf eine Spiralfeder d fegt. Die kugelig ausgebildete Fläche c der Hülse b wird von einer Spiralfeder e dicht gegen den ebenfalls kugelig geformten Teil f des Unterteils g gedrückt, welcher mit dem Oberteil h durch Schrauben i und eine Dichtung k fest verbunden ist. Der Oberteil k ist zweckmäßig zum Ansetzen einer Zange oder sonstiger Werkzeuge mit einem Sechskant L zum. Einschrauben des Gewindestutzens m in die Bußeiserne Abzweigdose ia versehen. Durch die Ausbildung der Hülse b als Kugelgelenk und vermittels der federnden Aufhängung des Rohres a sowie durch ihre dichte, Geschlossenheit, welche durch Einführen einer Stopfbüchse in den rohrförmigen Teil a noch erhöht wird, eignet s-ch die Aufhängevorrichtung besonders für chemische Fabriken, . für Bergwerke, Kesselhäuser und sonstige feuchte Räume, ferner für alle die Betriebe, bei denen durch Erschütterungen von Maschinenanlagen erfahrungsgemäß die Lebensdauer der Glühfäden eine kurze ist.The object of the invention consists of a tubular hanger a, which is guided in a sleeve b. The tube a is provided with a thread - for attaching the lamps on the one hand, and on the other hand has a flanged edge - which sweeps onto a spiral spring d. The spherical surface c of the sleeve b is pressed tightly by a spiral spring e against the likewise spherical part f of the lower part g, which is firmly connected to the upper part h by screws i and a seal k. The upper part k is useful for applying a pair of pliers or other tools with a hexagon L for. Screw the threaded connector m into the iron junction box ia. Due to the design of the sleeve b as a ball joint and by means of the resilient suspension of the tube a as well as its tight, closed nature, which is increased by inserting a stuffing box into the tubular part a, the suspension device is particularly suitable for chemical factories. for mines, boiler houses and other damp rooms, as well as for all those businesses where experience has shown that the service life of the filaments is short due to vibrations in machinery.
