Vorrichtung zum gegenseitigen Arretieren der Teleskopteile einer Betätigungsstange für elektrische AnlagenDevice for mutual locking of the telescopic parts of an operating rod for electrical systems
Es ist bekannt, die teleskopartig ineinander verschiebbaren Teile einer Betätigungsstange für elektrische Anlagen, insbesondere einer Erdungsstange, dadurch gegeneinander gegen Verdrehen und Verschieben zu arretieren, daß eine Muffe vorgesehen ist, die mit ihrem einen Teil auf dem Ende der Außenstange angebracht ist, während der andere Teil, in dem die Innenstange verschiebbar ist, geschlitzt und mittels einer Schraube mit Sterngriff zusammendrückbar i&t. Diese bekannte Vorrichtung erfüllt üblicherweise die an sie gestellten Forderungen. Wenn die Betätigungsstange allerdings sehr hohen Beanspruchungen ausgesetzt ist, z.B. von größerer Höhe fallen gelassen wird, kann der geschlitzte Teil d^r Muffe brechen.It is known that the telescoping parts of an operating rod for electrical systems, in particular a grounding rod, thereby locking against each other against rotation and displacement that a A sleeve is provided, one part of which is attached to the end of the outer rod, while the other part, in which the inner rod is slidable, slotted and compressible by means of a screw with a star grip i & t. This known device usually meets the requirements placed on it. If the operating rod, however is exposed to very high loads, e.g. is dropped from a great height, the slotted part d ^ r Break the socket.
Der Neuerung liegt die Aufgabe zugrunde, öine Vorrichtung zum gegenseitigen Arretieren der Teleskopteile einer Betätigungsstange für elektrische Anlagen zu schaffen, die hohen Beanspruchungen standhält. Zur Lösung der Aufgabe wird vorgeschlagen, daß die Innenstange von einem Spannband umfaßt ist, das durch Langlöcher in der Außenstange reicht und gegen die Außenstange spannbar ist. Das die Innenstange teilweise, z.B. etwa halbkreisförmig, umgebende SpannbandThe object of the innovation is to provide a device for mutual locking of the telescopic parts of an operating rod for electrical systems to create the high Withstands stresses. To solve the problem, it is proposed that that the inner rod is encompassed by a strap that extends through elongated holes in the outer rod and can be clamped against the outer rod. The tightening strap that partially surrounds the inner rod, e.g. in an approximately semicircular shape
ist einmal dadurch geschützt, daß es im Inneren der Außenstange geführt ist. Des weiteren beeinträchtigen die Langlöcher in der Außenstange dessen Belastbarkeit nur in unmerklichem, d.h. vernachlässigbarem Umfang.is protected once by the fact that it is guided inside the outer rod. Furthermore, the affect Oblong holes in the outer bar whose load-bearing capacity is only imperceptible, i.e. negligible.
Die Enden des Stahlbandes können an einem Druckstück befestigt sein, in dem eine auf die Außenseite der Außenstange drückbare Schraube geführt ist. Um die außen liegenden Teile der Arretiervorrichtung zu schützen, ist die Schraube vorzugsweise in einem schalenförmigen Handgriff angebracht, der das Druckstück überdeckt.The ends of the steel band can be attached to a pressure piece in which one is attached to the outside of the outer rod pushable screw is guided. In order to protect the external parts of the locking device the screw is preferably mounted in a bowl-shaped handle that covers the pressure piece.
Eine beispielhafte Ausführungsform der Neuerung ist in der Zeichnung dargestellt, und zwar sindAn exemplary embodiment of the innovation is shown in shown in the drawing, namely
Fig. 1 eine Seitenansicht eines Abschnittes der Teleskopstange mit der Arretiervorrichtung, teilweise im Längsschnitt undFig. 1 is a side view of a portion of the telescopic rod with the locking device, partially in Longitudinal section and
Fig. 2 ein Querschnitt durch die Vorrichtung.Fig. 2 is a cross section through the device.
Die Betätigungsstange weist die Innenstange 1 und die Außenstange 2 auf, die teleskopartig ineinander verschiebbar sind. Um die Innenstange 1 ist halbkreisförmig das Spannband gelegt, das durch Langlöcher 4- und 5 in der Außenstange 2 reicht. Die Enden des Spannbandes 3 sind mittels Schrauben 6 und 7 an den Seiten des Druckstücks 8 befestigt. In dem Druckstück 8 ist eine Schraube 9 schraubbar geführt, die mit ihrer vorderen Stirnseite an die Außenstange 2 drückbar ist. Am hinteren Ende ist die Schraube 9 in einem schalenförmigen Handgriff 10 befestigt. Die Außenstange 2 ist im Bereich der Verbindung von einem Blechrohr 11 umgeben.The actuating rod has the inner rod 1 and the outer rod 2, which can be telescoped into one another are. The tensioning strap is placed around the inner rod 1 in a semicircle, which is inserted through elongated holes 4 and 5 in the outer rod 2 enough. The ends of the tension band 3 are fastened to the sides of the pressure piece 8 by means of screws 6 and 7. By doing Pressure piece 8, a screw 9 is screwed out, the front face of which can be pressed against the outer rod 2 is. At the rear end, the screw 9 is fastened in a bowl-shaped handle 10. The outer rod 2 is in The area of the connection is surrounded by a sheet metal tube 11.
Durch Anziehen bzw. Lösen der Schraube 9 mittels des Handgriffs 10 wird die Arretierung zwischen der Innenstange 1 und der Außenstange 2 hergestellt bzw» freigegeben.By tightening or loosening the screw 9 by means of the handle 10, the locking between the inner rod 1 and the outer rod 2 produced or »released.
