Abstract

The bracket arm (2) supports an external lamp at its free end and has a parallel guide at the side for attaching it to the upper end of a lamp post, provided by a pair of couplings. These are formed as a pair of shells (41,42) displaced along the lamp post and secured to the bracket arm via distance holders (71,72). The upper shell is fitted with an end cap (6), forming a concentric extension of the lamp post when the bracket arm is fitted to the latter, one of the distance holders acting as a cable guide for the lamp supply cable.

Description

Die Erfindung bezieht sich auf einen Auslegerarm für eine Außenleuchte gemaß dem Oberbegriff des Patentanspruches 1.The invention relates to a cantilever arm for an outdoor lamp according to the preamble of claim 1.

Neben in ihrer Formgebung im wesentlichen funktional gestalteten Außenleuchten sind auch Außenleuchten auf dem Markt, die bei aller Optimierung im Hinblick auf ihre lichttechnische Funktion dennoch in ihrer äußeren Gestaltung früheren Leuchtenformen nachgebildet sind. Sie werden deshalb häufig als dekorative oder auch nostalgische Leuchten bezeichnet und sind für die Beleuchtung von Straßen oder Platzen bestimmt, bei denen sie sich in ihre Umgebung auch ästhetisch eingliedern sollen. Häufig besitzen Außenleuchten dieser Gruppen einen geschwungenen Auslegerarm, der einerseits die eigentliche Leuchte tragt und andererseits am Ende eines freistehenden Mastes, des sogenannten Mastzopfes festgelegt sind.In addition to the essentially functionally designed outdoor lights, there are also outdoor lights on the market that, despite all optimization with regard to their lighting function, are modeled in their outer design from previous lamp shapes. They are therefore often referred to as decorative or nostalgic lights and are intended for illuminating streets or squares, where they should also be aesthetically integrated into their surroundings. Outside lights of these groups often have a curved extension arm, which on the one hand carries the actual light and on the other hand are fixed at the end of a free-standing mast, the so-called mast spigot.

Was diesen Typ von Außenleuchten bisher unter anderem verteuert, ist die konstruktive Verbindung von Leuchtenmast und Auslegerarm. Maste für die obengenannten, im wesentlichen funktional gestalteten Serienleuchten sind üblicherweise am Mastzopf offen. Denn bei den Serienleuchten wird das Leuchtengehäuse über ein hohles Mastansatzstück auf den Mastzopf aufgeschoben und befestigt. So können Kabel zur elektrischen Versorgung der Außenleuchte im Inneren des Mastes gefuhrt und Ober das Mastansatzstuck unmittelbar in das Leuchtengehäuse gelegt werden.One of the things that has made this type of outdoor luminaires more expensive up to now is the constructive connection between the luminaire mast and the extension arm. Masts for the above-mentioned, essentially functionally designed series lights are usually open at the top of the mast. Because with the standard luminaires, the luminaire housing is slid onto the mast spigot and fastened using a hollow mast extension. In this way, cables for the electrical supply of the outdoor light can be routed inside the mast and placed directly above the mast extension in the luminaire housing.

Bei der hier diskutierten Gruppe von dekorativen Außenleuchten werden üblicherweise Sondermaste eingesetzt, die am Mastzopf abgeschlossen sind, weil der Auslegerarm für die Außenleuchte am Mastende seitlich angesetzt wird. Im Ansatzbereich des Auslegerarmes besitzt der Leuchtenmast etwa in Zopfhohe einen seitlichen Durchbruch zum Durchfuhren des Kabels in den mittels eines Zwischenstuckes auf Abstand an dem Leuchtenmast befestigten Auslegerarm. Die übliche konstruktive Ausgestaltung der Verbindung des Auslegerarmes mit dem Leuchtenmast, etwa als vorgefertigte einteilige Schweißkonstruktion oder auch als zweiteilige Ausfuhrung mit separatem Auslegerarm, der bei der Leuchtenmontage mittels einer Schraubverbindung am Mastzopf festgelegt wird, ist aufwendig und wenig montagefreundlich.In the group of decorative outdoor lights discussed here, special masts are usually used, which are closed at the top of the mast because the extension arm for the outdoor light is attached to the side of the mast. In the attachment area of the cantilever arm, the lamp mast has a lateral opening at about the height of a pigtail to allow the cable to pass through the cantilever arm attached at a distance to the lamp mast by means of an intermediate piece. The usual structural design of the connection of the extension arm to the lamp mast, for example as a prefabricated one-piece welded construction or as a two-part version with a separate extension arm, which is fixed during lamp installation by means of a screw connection on the mast spigot, is complex and not very easy to install.

Der Erfindung liegt daher die Aufgabe zugrunde, für einen Auslegerarm einer Außenleuchte der eingangs genannten Art eine weitere Ausführungsform zu schaffen, die in Verbindung mit Standardmasten einsetzbar ist, einfach an dem Mastzopf festlegbar ist, dabei keinen besondere Positionieraufwand erfordert und schließlich sicher am Mastzopf mit einfachen Mitteln zu befestigen ist.The invention is therefore based on the object to provide a cantilever arm of an outdoor light of the type mentioned, another embodiment that can be used in conjunction with standard masts, is easy to fix on the mast spigot, does not require any special positioning effort and finally safely on the mast spigot with simple To fix means.

Bei einem Auslegerarm der eingangs genannten Art wird diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Patentanspruches 1 beschriebenen Merkmale gelost.In a cantilever arm of the type mentioned, this object is achieved according to the invention by the features described in the characterizing part of patent claim 1.

Der erfindungsgemäße Auslegearm ist als ein Mastaufsatzelement gestaltet, das sich beim Aufsetzen auf den Mastzopf des freistehenden Leuchtenmastes selbst zentriert und unter seinem Eigengewicht auf dem Rand des Mastzopfes rastend aufsitzt. Es ist gegebenenfalls lediglich durch eine Drehbewegung um die Achse des Mastes gegenüber dem Leuchtenmast auszurichten und wird mit seiner unteren, über den Mastzopf geschobenen Schelle an diesem festgeklemmt, d. h. gegen ein Verdrehen gesichert. Fur den Leuchtenmonteur ist diese Montage von einer Hubbühne aus problemlos und sicher vorzunehmen. Es bedarf weder einer aufwendigen Justierung, noch sind für die Montage besondere Werkzeuge erforderlich. Neben der einfachen und damit kostengünstigen Montage hat die erfindungsgemäße Lösung den weiteren Kostenvorteil, daß in diesem Fall auch bei dekorativen Außenleuchten keine Sonderformen für die Maste benötigt werden. Damit ist eine Typenreduzierung möglich, die bei aller Vielfalt von Leuchtenformen Herstellungskosten, Lagerhaltung und Bestellaufwand verringert.The extension arm according to the invention is designed as a mast attachment element which, when placed on the mast spigot of the free-standing lamp mast, centers itself and rests under its own weight on the edge of the mast spigot. If necessary, it can only be aligned with the luminaire mast by a rotary movement about the axis of the mast and is clamped to it with its lower clamp, which is pushed over the mast braid, ie secured against twisting. For the luminaire fitter, this assembly can be carried out easily and safely from a lifting platform. No complex adjustment is required, and special tools are not required for assembly. In addition to the simple and therefore inexpensive assembly, the solution according to the invention has the further cost advantage that in this case no special shapes are required for the masts even in the case of decorative outdoor lights. This is a type reduction possible, which reduces manufacturing costs, warehousing and ordering costs with all the variety of luminaire shapes.

Weiterbildungen der erfindungsgemäßen Lösung sind in Unteransprüchen beschrieben und werden in der nachfolgenden Beschreibung eines Ausführungsbeispieles der Erfindung im einzelnen dargestellt.Further developments of the solution according to the invention are described in subclaims and are shown in detail in the following description of an embodiment of the invention.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung naher erläutert, dabei zeigt:

  • Figur 1 eine Gesamtansicht einer Außenleuchte mit einem als Mastaufsatzelement ausgebildeten Auslegerarm, der Mast und Leuchte verbindet,
  • Figur 2 einen Schnitt durch den Auslegerarm und das obere Mastende, den sogenannten Mastzopf sowie schematisch die Fuhrung eines Versorgungskabels für die Außenleuchte,
  • Figur 3 einen Teilschnitt durch das mastseitige Ende des Auslegerarmes,
  • Figur 4 und Figur 5 je einen Querschnitt durch den Auslegerarm längs Schnittlinien IV/IV bzw. V/V in der Ansicht von Figur 3.
An embodiment of the invention is explained in more detail below with reference to the drawing, which shows:
  • FIG. 1 shows an overall view of an outdoor light with a cantilever arm designed as a mast attachment element, which connects the mast and the light,
  • FIG. 2 shows a section through the extension arm and the upper end of the mast, the so-called mast spigot, and schematically the routing of a supply cable for the outdoor light,
  • FIG. 3 shows a partial section through the mast-side end of the extension arm,
  • 4 and 5 each show a cross section through the extension arm along section lines IV / IV and V / V in the view from FIG. 3.

In Figur 1 ist ein Beispiel für eine sogenannte dekorative Außenleuchte dargestellt, die auf einen steigenden Bedarf nach humaner Gestaltung von Innenstädten, Ortskernen und Wohnbereichen formal abgestimmt ist. Typisch für derartige Außenleuchten ist, daß die eigentliche Leuchte 1, dargestellt ist ein Beispiel mit einem glockenförmigen Leuchtenaufsatz 11 und einer kugelkalottenförmigen Leuchtenabdeckung 12, über einen hier bogenförmigen Auslegerarm 2 mit dem oberen Ende, dem sogenannten Mastzopf 3 eines freistehenden Leuchtenmastes über Zwischenstücke verbunden ist. Derartige Außenleuchten werden seit Jahren eingesetzt. Nun haben aber Standardmaste für Außenleuchten üblicherweise einen offenen Mastzopf, weil die in überwiegender Zahl eingesetzten, rein funktional gestalteten Serienleuchten in der Außenbeleuchtung üblicherweise über ein hohles Mastansatzstuck auf den Mastzopf aufgeschoben werden, um eine einfache Verlegung der Versorgungskabel für die Leuchte durch das hohle Mastansatzstuck hindurch zu ermöglichen. Wenn aber der Auslegerarm für die hier geschilderte Außenleuchte am Mastende seitlich angesetzt wird, muß der Mastzopf oben abgeschlossen sein. Stattdessen ist im Ansatzbereich des Auslegerarmes eine seitliche Öffnung am Mastende zum Durchführen des Versorgungskabels für die Leuchte erforderlich. Dies bedingt in der Herstellung und Lagerhalterung teuere Sonderformen der Leuchtenmaste.FIG. 1 shows an example of a so-called decorative outdoor lamp, which is formally matched to an increasing need for humane design in inner cities, town centers and living areas. It is typical of such outdoor lights that the actual lamp 1, an example is shown with a bell-shaped lamp cap 11 and a spherical cap-shaped lamp cover 12, is connected via an arch-shaped cantilever arm 2 to the upper end, the so-called mast spigot 3 of a free-standing lamp mast via intermediate pieces. Such outdoor lights have been used for years. Now we have standard masts for outdoor luminaires usually an open mast spigot, because the predominantly number of purely functionally designed standard luminaires in the exterior lighting are usually pushed onto the mast spigot via a hollow mast piece in order to make it easy to lay the supply cable for the luminaire through the hollow mast piece. If, however, the extension arm for the exterior light described here is attached to the side of the mast end, the mast spigot must be closed at the top. Instead, a lateral opening at the mast end is required in the attachment area of the cantilever arm to lead through the supply cable for the lamp. This requires expensive special forms of the lamp poles in the manufacture and storage.

In Figur 2 ist schematisch in einem Schnitt durch einen am Mastzopf 3 montierten Auslegerarm 2 eine erfindungsgemäße Ausgestaltung einer Mastverbindung dargestellt, mit der dieser bei konventionellen Losungen erforderliche Aufwand reduzierbar ist. Bei dieser Losung ist der Mastzopf 3 wie bei einem Standardmast oben offen. Der bogenförmige Auslegerarm 2 ist mittels zweier als Schellen 41 bzw. 42 ausgebildeter Verbindungsstücke am Mastzopf 3 festgelegt. Ein Kabel 5 für die elektrische Versorgung der Leuchte 1 ist vom Mastzopf 3 durch die obere Schelle 41 hindurch in den Auslegerarm 2 gefuhrt. Von oben her ist in diese Schelle 41 eine als Hohlzylinder ausgebildete, oben abgeschlossene Endkappe 6 koaxial eingeführt, die mit dieser Schelle 41 fest verbunden ist. Das offene, innerhalb der oberen Schelle 41 sitzende untere Ende der Endkappe 6 sitzt unmittelbar auf dem Rand des Mastzopfes 3 auf.FIG. 2 shows schematically in a section through an extension arm 2 mounted on the mast spigot 3 an embodiment of a mast connection according to the invention, with which this effort required in conventional solutions can be reduced. With this solution, the mast spigot 3 is open at the top like a standard mast. The arcuate cantilever arm 2 is fixed to the mast spigot 3 by means of two connecting pieces designed as clamps 41 and 42, respectively. A cable 5 for the electrical supply of the lamp 1 is led from the mast braid 3 through the upper clamp 41 into the extension arm 2. An end cap 6, which is designed as a hollow cylinder and is closed at the top, is coaxially inserted into this clamp 41 from above and is firmly connected to this clamp 41. The open lower end of the end cap 6, which is seated within the upper clamp 41, is seated directly on the edge of the mast braid 3.

Der in Figur 3 gezeigte Teilschnitt des mastseitigen Teiles des Auslegerarmes 2 verdeutlicht diese konstruktive Losung. An dem mastseitigen Ende des bogenförmigen Auslegerarmes 2 sind die beiden Schellen 41 und 42 über kurze, hohle Abstandshalter 71 bzw. 72 mittels Schweißverbindungen festgelegt. Durch den oberen Abstandshalter 71, der mit seitlichen Durchbrüchen 21 sowie 411 im Auslegerarm 2 bzw. der oberen Schelle 41 fluchtend festgelegt ist, wird das Kabel 5 für die elektrische Versorgung der Außenleuchte 1 hindurchgeführt. In die obere Schelle 41 ist die Endkappe 6 eingeschoben. Sie besitzt am unteren, offenen Ende, dem seitlichen Durchbruch 410 der oberen Schelle 41 zugekehrt, eine halbseitige Auskerbung 61 für die Durchführung des Kabels 5.The partial section shown in Figure 3 of the mast-side part of the boom arm 2 illustrates this constructive solution. At the mast-side end of the arcuate cantilever arm 2, the two clamps 41 and 42 are fixed by means of short, hollow spacers 71 and 72 by means of welded connections. Through the upper spacer 71, the side Breakthroughs 21 and 411 is set in alignment in the cantilever arm 2 or the upper clamp 41, the cable 5 is passed through for the electrical supply of the exterior light 1. The end cap 6 is pushed into the upper clamp 41. At the lower, open end, which faces the lateral opening 410 of the upper clamp 41, it has a half-sided notch 61 for the passage of the cable 5.

In Figur 4 ist in einem Schnitt längs der Schnittlinie IV/IV von Figur 3 diese Einzelheit des Auslegerarmes 2 zur Verdeutlichung dargestellt. In unterbrochenen Linien ist der Querschnitt des Mastzopfes angedeutet, auf dem der untere Rand der Endkappe 6 im montierten Zustand aufsitzt. Um einen eindeutigen Sitz der Endkappe 6 auf dem Mastzopf 3 zu erreichen, sind Randecken 62 der Auskerbung 61 nach innen abgekantet.In Figure 4, this detail of the cantilever arm 2 is shown in a section along the section line IV / IV of Figure 3 for clarification. The cross section of the mast braid on which the lower edge of the end cap 6 is seated in the assembled state is indicated in broken lines. In order to achieve a clear fit of the end cap 6 on the mast braid 3, edge corners 62 of the notch 61 are folded inwards.

In Figur 5 ist ein Querschnitt durch den Auslegerarm 2 längs der Schnittlinie V/V von Figur 3 dargestellt. Dabei verdeutlicht dieser Schnitt die Funktion der unteren Schelle 42 des Auslegerarmes 2 bei der Parallelfuhrung des Auslegerarmes 2 sowie dessen Festlegung am Mastzopf 3. Durchbrüche im Auslegerarm 2 bzw. der Schelle 42 sind hier nicht erforderlich. Zusätzlich besitzt die untere Schelle 42 aber zwei, auf ihrem Umfang verteilt angeordnete Gewindebohrungen 420 zum Aufnehmen von Feststellschrauben 8, mit denen die untere Schelle 42 auf dem Umfang des Mastzopfes 3 in Form einer Spreizverbindung festgeklemmt wird. Damit ist der Auslegerarm 2 gegen ein Verdrehen relativ zum Mastzopf 3 gesichert.FIG. 5 shows a cross section through the extension arm 2 along the section line V / V of FIG. 3. This section illustrates the function of the lower clamp 42 of the cantilever arm 2 in the parallel guidance of the cantilever arm 2 and its fixing on the mast spigot 3. Breakthroughs in the cantilever arm 2 or the clamp 42 are not necessary here. In addition, the lower clamp 42 has two threaded bores 420 arranged around its circumference for receiving locking screws 8, with which the lower clamp 42 is clamped onto the circumference of the mast spigot 3 in the form of an expansion connection. The cantilever arm 2 is thus secured against twisting relative to the mast spigot 3.
