Description

nach oben randoSene Durchlaßöffnung la' der Stirnwand la hindurchgeführt und in eine Gewindebohrung des Mastes 3 eingeschraubt ist.upwards randoSene passage opening la ' passed through the end wall la and screwed into a threaded hole in the mast 3.

Der innenseitige obere Bereich der Stirnwand la bzw. die Kopfschraube 5 ist von aer Leuchtenseite her durch einen in Längsrichtung des Auslegerarms 2 oberseitig aus dem Auslegermaterial ausgesparten Schlitz Ib für mindestens ein Verdrehwerkzeug (nicht eingezeichnet), beispielsweise einen Schraubenzieher, einen Steck- bzw. Imbusschlüssel, für die Schraube 5 zugänglich, wobei der Längsschlitz Ib mit einem zumindest dem 2fachen Gewindebolzenquerschnitt der Schraube 5 entsprechenden Schlitzquerschnitt ausgebildet und in dessen Bereich die Durchlaßöffnung la' für die Schraube5 angeordnet ist. Der Längsschlitz Ib des Auslegerarms2 ist von der Stirnwand la bis zu einer wenigstens mit dem 2fachen Gewindebolzenquerschnitt der Schraube 5 ausgebildeten Durchbrechung 1 α dss mit dem Auslegerarm 2 verbundenen Leuchtenteils 1 verlängert und mündet in dessen Innenraum.The inner upper area of the end wall la or the head screw 5 is from the lamp side through a slot Ib cut out of the cantilever material on the upper side in the longitudinal direction of the cantilever arm 2 for at least one twisting tool (not shown), for example a screwdriver, a socket or Allen key , accessible for the screw 5, wherein the longitudinal slot Ib is formed with a slot cross-section corresponding to at least twice the threaded bolt cross-section of the screw 5 and the passage opening la ' for the screw 5 is arranged in its area. The longitudinal slot Ib of the cantilever arm 2 is extended from the end wall la to an opening 1 α dss connected to the cantilever arm 2 with at least twice the threaded bolt cross section of the screw 5 and opens into its interior.

Der untere Innenseitenbereich der Stirnwand la ist gleichfalls von der Leuchtenseite her durch einen in Längsrichtung des Auslegerarms 2 unterseitig aus dem Auslegermaterial ausgesparten Schlitz Ic für mindestens ein Nietwerkzeug zugänglich, durch das der Steckbolzen4 mit der Stirnwand la vernietet werden kann.The lower inside area of the end wall la is also accessible from the lamp side through a slot Ic cut out of the cantilever material on the underside in the longitudinal direction of the cantilever arm 2 for at least one riveting tool, through which the socket pin 4 can be riveted to the end wall la.

Bei der in der Zeichnung dargestellten Leuchte besteht der Auslegerarm aus zwei über die Stirnwand la einstückig miteinander im gegenseitigen Abstand verbundenen Seitenwänden ld, Ie sowie einem diese gegenseitig abstützenden Längssteg 2 /, der zwischen den beiden Längsschlitzen Ib, Ic angeordnet ist. Der Längssteg If bildet den Boden des oberen Längsschlitzes 2 b. In the lamp shown in the drawing, the cantilever arm consists of two side walls ld, Ie which are integrally connected to one another at a mutual spacing via the end wall la , and a longitudinal web 2 / which is arranged between the two longitudinal slots Ib, Ic . The longitudinal web If forms the bottom of the upper longitudinal slot 2 b.

Die Stirnwand la des Aiislegerorms2 ist zwecks einer stabilen Abstützung sowohl gegen den Mast 3 als auch gegen eine Wand außenseitig im Querschnitt stufenartig hinterschnitten. Die Tiefe dieser Querschnittshinterschneidung ist beim Auslegerarm 2 einer Mastleuchte in Abhängigkeit vom Durchmesser des Mastes 3 derart bemessen, daß bei nicht angezogener Kopfschraube 5 der hinterschnittene Querschnittsbereich durch die darüber vorspringend am Mast anliegenden Querschnittsbereiche von der Mastoberfläche einen geringen Abstand aufweist und erst durch das Anziehen der Kopfschraube 5 bis zur Anlage am Mast verformt wird. Dies gewährleistet einen erhöhten Verdrehungsschutz des Auslegerarms 2 bezüglich dessen Längsachse und einen sauberen Preßsitz der über den hinterschnittenen Querschnittsbereich vorspringenden Querschnittsbereich der Stirnwand 2 a.
Wenngleich die Stirnwand la des Auslegerarms2 mit einem stufenartig hinterschnittenen, etwa U-förmigen, Querschnitt ausgebildet ist, könnte diese Querschnittshinterschneidung auch dreieck- oder bogenförmig mit den vorher beschriebenen Paßmaßen ausgebildet sein. Es könnte der Steckbolzen 4 mit dem Auslegerarm 2 ausgebildet, beispielsweise angegossen sein.The end wall la of the Aiislegerorms2 is for the purpose of stable support both against the mast 3 and against a wall on the outside undercut in cross-section in a stepped manner. The depth of this cross-sectional undercut is dimensioned in the cantilever arm 2 of a mast light depending on the diameter of the mast 3 such that when the head screw 5 is not tightened, the undercut cross-sectional area is at a small distance from the mast surface due to the cross-sectional areas protruding above it on the mast and only when the Head screw 5 is deformed until it rests on the mast. This ensures increased protection against rotation of the cantilever arm 2 with respect to its longitudinal axis and a clean interference fit of the cross-sectional area of the end wall 2a protruding beyond the undercut cross-sectional area .
Although the end wall la of the cantilever arm 2 is designed with a step-like undercut, approximately U-shaped, cross-section, this cross-sectional undercut could also be triangular or arcuate with the dimensions described above. The socket pin 4 could be formed with the cantilever arm 2, for example it could be cast on.

The lamp arm according to the German wall and only has to be firmly connected to the latter by means of laid-open specification 1 539 426 pointing upwards by tightening the screw. Since the open box cross-section and the 4 ° light through the front wall, which is open at the top, is relieved of radiative forces from the front wall on both sides of the latter towards the rear, and protruding legs that are only subjected to tension when fastening, can also counteract that of the cantilever arm Remove the wall or the mast - tighten the screw without cutting or breaking supports. However, this fastening is particularly dangerous for the latter, with the least amount of force applied over a greater length and consequently with a 45. As a result, even greater weight of the cantilever arm can be very difficult, mast or wall lights with long, ie heavy, since this must first be held by hand in the carrying position on the cantilever arms effortlessly for a very short time on the mast or on the wall, secure against rotation on the mast or on attach to the wall,
