Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device according to the preamble of claim 1.

Mastleuchten besitzen ein Gehäuse, an dem ein Fortsatz angeformt ist, in den das freie Ende eines Mastes einfügbar ist. Innerhalb dieses Fortsatzes, der der Außenkontur des Mastendes angepaßt ist, ist eine Innenleiste als Anschlag für das Mastende vorgesehen, die einen Durchbruch aufweist, durch den die Kabel hindurchgefädelt werden müssen. An dieser Stelle ist auch eine Kabelverschraubung zur Erzielung einer Dichtung, vorzugsweise IP 54, vorzusehen und auch durch diese Kabelverschraubung müssen die Kabel hindurchgefädelt werden. Diese Montage einer Hastleuchte in einer Höhe von ca. 4 m bis 5 m über Grund ist daher recht kompliziert.Mast lights have a housing on which an extension is formed, into which the free end of a mast can be inserted. Within this extension, which is adapted to the outer contour of the mast end, an inner bar is provided as a stop for the mast end, which has an opening through which the cables must be threaded. A cable gland to achieve a seal, preferably IP 54, must also be provided at this point and the cables must also be threaded through this cable gland. This assembly of a hasty lamp at a height of approx. 4 m to 5 m above ground is therefore quite complicated.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, mit der die Montage einer Mastleuchte am freien Ende des Mastes und insbesondere die Zuführung des Kabels zur Leuchte erheblich vereinfacht wird.The object of the invention is to provide a device of the type mentioned, with which the assembly of a mast lamp at the free end of the mast and in particular the supply of the cable to the lamp is considerably simplified.

Diese Aufgabe wird erfindungsgemäß gelöst durch die kennzeichnenden Merkmale des Anspruches 1.This object is achieved according to the invention by the characterizing features of claim 1.

Erfindungsgemäß also sind Mittel zur Halterung und Fixierung einer wenigstens eine Durchbrechung enthaltende Platte am inneren Ende des Rohrfortsatzes angeordnet, wobei in die Durchbrechungen die Kabelverschraubung zur Halterung, Zugentlastung und Fixierung des eingeführten, zur Leuchte weitergeführten Kabels einschraubbar sind.According to the invention, means for holding and fixing a plate containing at least one opening are arranged at the inner end of the tubular extension, the cable gland for holding, strain relief and fixing the inserted cable, which is led to the lamp, being screwable into the openings.

Die Mittel umfassen gemäß Anspruch 2 einen U-förmigen Haltebügel, der an der Innenkante der U-Form eine Rille aufweist, in die der Rand der Platte eingefügt ist, so daß der Haltebügel die Platte an Wenigstens zwei sich gegenüberliegenden Kanten mit seinen Schenkeln umfaßt; der Bügel ist im Gehäuse festgelegt.The means comprise according to claim 2 a U-shaped bracket which has a groove on the inner edge of the U-shape into which the edge of the plate is inserted so that the bracket surrounds the plate with at least two opposite edges with its legs; the bracket is fixed in the housing.

Bei der erfindungsgemäßen Ausgestaltung wird demgemäß zunächst das Kabel durch den Fortsatz am Leuchtengehäuse hindurchgefädelt und dann der Rohrfortsatz über das freie Ende des Mastes gesteckt und dort befestigt. Das Kabel wird dann durch die wenigstens eine Durchbrechung in der Platte hindurchgeführt. Danach wird das Kabel durch die Kabelverschraubung hindurchgeführt und die Kabelverschraubung an der Platte befestigt. Sodann wird der Haltebügel so über die Platte geschoben, daß sich gegenüberliegende Seitenkanten in die U-förmigen Rillen der Schenkel eingreifen und dann die Platte zusammen mit dem Haltebügel im Anschlußraum festgelegt, wobei die Fixierung der Platte einerseits durch das Mastende und andererseits durch die Festlegung des Haltebügels zwischen einer auf die offene Seite des Anschlußraumes aufgeschraubten Deckels und den Boden des Anschlußraumes bewirkt wird.In the embodiment according to the invention, the cable is accordingly first threaded through the extension on the lamp housing and then the tubular extension is pushed over the free end of the mast and fastened there. The cable is then passed through the at least one opening in the plate. Then the cable is passed through the cable gland and the cable gland is attached to the plate. Then the bracket is pushed over the plate so that opposite side edges engage in the U-shaped grooves of the legs and then the plate is fixed together with the bracket in the connection space, the fixation of the plate on the one hand by the mast end and on the other hand by the definition of Holding bracket between a screwed onto the open side of the connection space and the bottom of the connection space is effected.

An diesen Deckel ist gemäß Anspruch 3 erfindungsgemäß ein Steg angeformt, der gegen die Außenkante des Haltebügelsteges drückt.According to the invention, a web is molded onto this lid, which presses against the outer edge of the retaining bar web.

Am Boden des Anschlußraumes sind zwei seitlich außerhalb der Platte (im montierten Zustand) befindliche Vorsprünge angeordnet, gegen deren eine, quer zur Längsrichtung des Leuchtengehäuses verlaufenden Seitenfläche die entsprechenden Seitenflächen der Schenkel des Haltebügels anliegen.At the bottom of the connection space, two protrusions located laterally outside the plate (in the assembled state) are arranged, against one of which, transversely to the longitudinal direction of the lamp housing running side surface, the corresponding side surfaces of the legs of the retaining bracket rest.

Dadurch, daß gemäß Anspruch 5 die Seitenflächen der Vorsprünge und des Haltebügels in einem spitzen Winkel zur Senkrechten zur Längserstreckung des Anschlußraumes bzw. zu dem Anschlußraum verlaufen, wird beim Einschieben des Haltebügels mit der Platte eine Verklemmung zwischen den Schenkeln des Haltebügels und den Vorsprüngen und dem freien Ende des Mastes erzielt.Characterized in that the side surfaces of the projections and the bracket are at an acute angle to the vertical to the longitudinal extent of the connection space or to the connection space, a jamming between the legs of the bracket and the projections and the when inserting the bracket with the plate achieved free end of the mast.

Damit nicht nur um die Kabel herum eine Abdichtung erzielt ist, ist auch um die Durchbrüche herum eine Dichtung vorgesehen, die im montierten Zustand gegen die Stirnkante des Mastendes gedrückt ist.So that a seal is not only achieved around the cable, a seal is also provided around the openings, which in the assembled state is pressed against the front edge of the mast end.

Am Boden des Gehäuses ist eine Leiste vorgesehen, die in eine daran angepaßte Ausnehmung an der Platte eingreift, so daß eine Verschiebung der Platte quer zu ihrer Plattenebene vermieden wird.At the bottom of the housing, a strip is provided which engages in a recess on the plate which is adapted to it, so that a displacement of the plate transversely to its plate plane is avoided.

Um zu erreichen, daß der Haltebügel zusammen mit der Platte eine vormontierbare Einheit bildet, sind an einer Seitenfläche der Platte Zapfen vorgesehen, hinter die Ansätze an den Schenkein federnd greifen. Beim Einfügen der Platte zwischen die Schenkel des Haltebügels verrasten Ansätze an den Schenkein hinter den Zapfen, wodurch der Haltebügel an der Platte festgelegt ist.In order to ensure that the bracket together with the plate forms a preassembled unit, pins are provided on one side surface of the plate, behind which approaches the legs do not engage resiliently. When inserting the plate between the legs of the bracket, approaches to the legs lock behind the pin, whereby the bracket is fixed to the plate.

Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung, sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen näher erläutert und beschrieben werden.The invention and further advantageous refinements and improvements are to be explained and described in more detail with reference to the drawing, in which an exemplary embodiment of the invention is shown.

Auf einem Mast 10 ist an dessen freiem Ende eine Mastleuchte 11 aufgesteckt.A mast light 11 is attached to a mast 10 at its free end.

Die Mastleuchte 11 besitzt ein Leuchtengehäuse 32, welches einen langgetreckt rechteckigen Querschnitt aufweist; an dessen in der Fig. 1 links befindlichen Seite ist ein trapezartiger Fortsatz 32a angeformt, der auf der dem Boden 31 (siehe Fig. 2) entgegengesetzt liegenden Fläche 32b eine nicht gezeigte Öffnung aufweist, die mit einem Deckel 42 verschlossen ist, dessen Außenkontur der Außenkontur des Fortsatzes 32a entspricht. Das Leuchtengehäuse 32 der Mastleuchte 11 ist dann mit einer transparenten Abdeckung 32c abgedeckt.The mast lamp 11 has a lamp housing 32 which has an elongated rectangular cross section; On its left side in FIG. 1, a trapezoidal extension 32a is formed, which on the surface 32b opposite the bottom 31 (see FIG. 2) has an opening, not shown, which is closed with a cover 42, the outer contour of which Corresponds to the outer contour of the extension 32a. The luminaire housing 32 of the mast luminaire 11 is then covered with a transparent cover 32c.

Der rohrförmig ausgebildete Mast 10 besitzt einen Innenraum 12, durch den hindurch Kabel (nicht dargestellt) gefädelt sind. Der Vorsprung 32a besitzt eine Eintrittsausnehmung 32d, in die das Mastende eingesteckt wird und die mittels einem radial nach innen vorspringenden Abschlußflansch 14 abgeschlossen ist, gegen die das Stirnende des Mastes 10 im montierten Zustand anschlägt und die eine Öffnung 13 umschließt bzw. begrenzt, die einen ovalen Querschnitt aufweist, siehe weiter unten. In der Wandung 32b befindet sich die Öffnung 32e, die einen Zugang zu einem Anschlußraum 32f freigibt. Dieser Anschlußraum ist im montierten Zustand mittels des Deckels 42 verschlossen.The tubular mast 10 has an interior 12 through which cables (not shown) are threaded. The projection 32a has an entry recess 32d into which the mast end is inserted and which is closed off by means of a radially inwardly projecting end flange 14, against which the front end of the mast 10 abuts in the assembled state and which encloses or delimits an opening 13 which one oval cross-section, see below. In the wall 32b there is the opening 32e, which gives access to a connection space 32f. This connection space is closed in the assembled state by means of the cover 42.

Die Öffnung 13 ist, wie aus den Fig. 3 und 4 hervorgeht, mittels einer Flanschplatte 15 verschlossen, die einen etwa rechteckigen Querschnitt aufweist. An der Flanschplatte 15 ist ein Gewindeflansch 16 angeformt, der senkrecht dazu vorsteht und so ausgebildet ist, daß er in die Öffnung 13 hineinpaßt. Der Gewindeflansch 16 ist von einer Rille 17 umgeben, in der sich eine Dichtung 18 befindet, die gegen die Stirnfläche 19 des Abschlußflansches 14 anliegt. Die Rille 17 ist von einer Leiste oder ggf. auch von zwei Leisten 20 umgeben, deren Höhe, von der Flanschplatte 15 aus gesehen, niedriger ist als die des Gewindeflansches 16. Innerhalb des Gewindeflansches 16 befindet sich bei der Ausführung gemäß Fig. 2 bis 4 ein Durchbruch 21 mit einem Innengewinde, in den das Außengewinde einer Kabelverschraubung 22 eingeschraubt ist. Es besteht natürlich auch die Möglichkeit, zwei derartige Durchbrüche mit Innengwinde vorzusehen, so daß zwei Kabelverschraubungen in die Platte 15 eingeschraubt werden können. Zur Fixierung der Flanschplatte 15 mit der Kabelverschraubung 22 ist ein U-förmiger Bügel 23 vorgesehen, der an seinen Innenkanten eine Halterille 24 besitzt, so daß sowohl der Steg 25 als auch die beiden Schenkel 26 und 27 einen U-förmigen Querschnitt aufweisen, dessen offene Seiten aufeinanderzugerichtet sind. Die U-Form ist so gewählt, daß die Schmalseitenkanten der Flanschplatte 15 in die U-Form an den Schenkeln 26 und 27 hineingreifen können.As can be seen from FIGS. 3 and 4, the opening 13 is closed by means of a flange plate 15 which has an approximately rectangular cross section. On the flange plate 15, a threaded flange 16 is formed, which projects perpendicular to it and is designed so that it fits into the opening 13. The threaded flange 16 is surrounded by a groove 17 in which a Seal 18 is located, which bears against the end face 19 of the end flange 14. The groove 17 is surrounded by a strip or possibly also by two strips 20, the height of which, viewed from the flange plate 15, is lower than that of the threaded flange 16. Inside the threaded flange 16, in the embodiment according to FIGS. 2 to 4 an opening 21 with an internal thread into which the external thread of a cable gland 22 is screwed. There is of course also the possibility of providing two such openings with internal threads so that two cable glands can be screwed into the plate 15. To fix the flange plate 15 with the cable gland 22, a U-shaped bracket 23 is provided, which has a retaining groove 24 on its inner edges, so that both the web 25 and the two legs 26 and 27 have a U-shaped cross section, the open Pages are facing each other. The U-shape is chosen so that the narrow side edges of the flange plate 15 can reach into the U-shape on the legs 26 and 27.

Der Bügel 23 besitzt an jedem seiner Schenkel auf einer Breitseite, die der durch den Bügel 23 aufgespannten Ebene entspricht, je eine Anformung 28, deren Außenfläche zu dieser Ebene einen spitzen Winkel bildet, wobei die Spitze des Winkels mit dem freien Ende jedes Schenkels zusammenfällt; die Schnittlinie zwischen der Breitseite jedes Schenkels und der Außenfläche jeder Anformung verläuft jeweils parallel zu der Längserstreckung des Steges 25 am Ende jedes Schenkels 26 und 27. Die Anformung 28 schließt an die Außenkanten 29 bzw. 30 der Schenkel 26 und 27 an und überdeckt etwa die Hälfte der Schenkel 26, 27 sowohl in Längsrichtung des Steges als auch in Längsrichtung jedes Schenkels 26, 27 gemessen. Im montierten Zustand, wenn die Flanschplatte 15 mit den Seitenkanten von der jeweiligen U-Form der Schenkel 26, 27 umfaßt sind, befinden sich die Anformungen 28 auf der Breitseite der Schenkel 26 und 27, die der Fläche der Flanschplatte 15, an der der Gewindeflansch 16 und die Leisten 20 angeformt sind, entgegengesetzt.The bracket 23 has on each of its legs on a broad side, which corresponds to the plane spanned by the bracket 23, a projection 28, the outer surface of which forms an acute angle to this plane, the apex of the angle coinciding with the free end of each leg; the line of intersection between the broad side of each leg and the outer surface of each projection runs parallel to the longitudinal extension of the web 25 at the end of each leg 26 and 27. The projection 28 adjoins the outer edges 29 and 30 of the legs 26 and 27 and covers approximately that Half of the legs 26, 27 measured both in the longitudinal direction of the web and in the longitudinal direction of each leg 26, 27. In the assembled state, when the flange plate 15 is surrounded by the respective U-shape of the legs 26, 27 with the side edges, the projections 28 are located on the broad side of the legs 26 and 27, that of the surface of the flange plate 15 on which the threaded flange 16 and the strips 20 are molded, opposite.

Am Boden 31 des Anschlußraumes 32f, auf dessen Innenseite, sind in Abstand zueinander Vorsprünge 33 und 34 angeformt, deren dem Mast zugewandten Seitenflächen 35 so abgeschrägt ist, daß die Dicke jedes Vorsprunges 33, 34, am Boden in Längsrichtung des Mastes bzw. des Mastendes gemessen, dicker ist als die des freien Endes des Vorsprunges. Diese Seitenflächen 35 sind den Schrägflächen der Anformungen 28 angepaßt, so daß dann, wenn der Bügel 23 zusammen mit der Flanschplatte 15 montiert ist, die Anformungen 28 der Schenkel 26 und 27 die Schrägflächen 35 berühren und auf diese auflaufen und so eine Verklemmung der Flanschplatte 15 mit dem Bügel 23 an der Stirnfläche des Endes des Abschlußflansches 14 bewirken.On the bottom 31 of the connection space 32f, on the inside, projections 33 and 34 are formed at a distance from one another, the side surfaces 35 facing the mast being chamfered such that the thickness of each projection 33, 34 on the bottom in the longitudinal direction of the mast or the mast end measured, is thicker than that of the free end of the projection. These side surfaces 35 are adapted to the inclined surfaces of the projections 28, so that when the bracket 23 is mounted together with the flange plate 15, the projections 28 of the legs 26 and 27 touch the inclined surfaces 35 and run onto them, thus jamming the flange plate 15 with the bracket 23 on the end face of the end of the end flange 14.

Die Flanschplatte 15 besitzt auf der Seite, auf der sich der Gewindeflansch 16 und die Außenleisten 20 befinden, Zapfen 36 und 37, die einen solchen Abstand voneinander aufweisen, daß die Innenkanten der Schenkel 26 und 27 gegen die Zapfen 36, 37 zum Anliegen kommen. Damit der Bügel 23 mit der Flanschplatte 15 eine handhabbare Einheit bildet, sind die auf der Seite der Platte 15, auf der sich die Zapfen 36 und 37 befinden, mit Nasen 38 und 39 versehen, die voneinander einen kleineren Abstand aufweisen, als der Abstand der Zapfen 36, 37, so daß die Zapfen zusammen mit den Nasen eine Verrastung bilden.The flange plate 15 has, on the side on which the threaded flange 16 and the outer strips 20 are located, pins 36 and 37 which are at such a distance from one another that the inner edges of the legs 26 and 27 come to bear against the pins 36, 37. So that the bracket 23 forms a manageable unit with the flange plate 15, those on the side of the plate 15, on which the pins 36 and 37 are located, are provided with lugs 38 and 39, which are at a smaller distance from one another than the distance between Pins 36, 37 so that the pins form a catch together with the lugs.

An der dem Boden 31 zugewandten Kante besitzt die Flanschplatte 15 eine Aussparung 40, in die ein Führungsvorsprung 41 eingreift, damit die Flanschplatte 15 bezogen auf den Boden 31 an Ort und Stelle gehalten ist.On the edge facing the bottom 31, the flange plate 15 has a recess 40 into which a guide projection 41 engages so that the flange plate 15 is held in place with respect to the bottom 31.

An dem Vorsprung 32a des Leuchtengehäuses 32 ist der Deckel 42 mittels Schrauben (nicht gezeigt) angebracht. Im Bereich 23 des Bügels besitzt der Deckel 42 eine senkrecht dazu verlaufende Stützwand 43, die sich gegen die Außenkante des Steges 25 im montierten Zustand anlegt und die Schenkel 26 und 27 des Bügels gegen die Schrägfläche 35 der Vorsprünge 32 und 33 drückt. Dadurch ist eine Verspannung des Bügels zusammen mit der Flanschplatte 5 sichergestellt. Die Dichtung 18 dient dabei zu einem Toleranzausgleich.The cover 42 is attached to the projection 32a of the lamp housing 32 by means of screws (not shown). In the area 23 of the bracket, the cover 42 has a support wall 43 running perpendicular to it, which bears against the outer edge of the web 25 in the assembled state and presses the legs 26 and 27 of the bracket against the inclined surface 35 of the projections 32 and 33. This ensures that the bracket is braced together with the flange plate 5. The seal 18 serves to compensate for tolerances.

An dem Deckel 42 befindet sich weiterhin eine Anschlagdichtung 44, so daß die Öffnung 32e des Anschlußraumes 32f nach außen abgedichtet ist.A stop seal 44 is also located on the cover 42, so that the opening 32e of the connection space 32f is sealed off from the outside.

Zur Montage wird zunächst das Leuchtengehäuse mit dem trapezförmigen Vorsprung 32a über das Ende des Mastes 10 gesteckt und das Kabel durch die Öffnung 13 hindurchgeführt. Danach fädelt man das Kabel durch die Flanschplatte 15 und dann durch die Kabelverschraubung 22 hindurch und die Kabelverschraubung 22 wird in die Flanschplatte eingeschraubt, so daß das Kabel gegenüber der Flanschplatte 15 abgedichtet sind. Bei zwei Kabeln sind zwei Kabelverschraubungen in die dazu vorbereitete Flanschplatt 15 einschraubbar (nicht dargestellt). Die Einheit der Flanschplatte 15 mit dem Bügel 23 und der Kabelverschraubung 23 wird dann vor die Stirnfläche des Abschlußflansches 14 gesetzt und der Bügel in Richtung Boden 31 gedrückt. Durch Befestigen des Deckels wird eine Verspannung der Flanschplatte 15 am Stirnende des Abschlußflansches 14 am Ende des Mastes 10 erzielt, in dem der Bügel 23 mit den Außenflächen der Anformungen 28 gege die Seitenflächen 35 gedrückt und aufgrund der Schrägstellung dieser Seitenflächen zusammen mit der Flanschplatte gegen die Stirnfläche des Abschlußflansches 14 gepreßt wird, so daß der Anschlußraum 32 bzw. das Leuchtengehäuse gegenüber dem Mast 10 abgedichtet sind.For assembly, the luminaire housing with the trapezoidal projection 32a is first inserted over the end of the mast 10 and the cable is passed through the opening 13. Then you thread the cable through the flange plate 15 and then through the cable gland 22 and the cable gland 22 is screwed into the flange plate, so that the cable is sealed against the flange plate 15. In the case of two cables, two cable glands can be screwed into the flange plate 15 prepared for this purpose (not shown). The unit of the flange plate 15 with the bracket 23 and the cable gland 23 is then placed in front of the end face of the end flange 14 and the bracket is pressed towards the bottom 31. By attaching the lid, a bracing of the flange plate 15 is achieved at the end of the end flange 14 at the end of the mast 10, in which the bracket 23 with the outer surfaces of the formations 28 against the side surfaces 35 pressed and due to the inclination of these side surfaces together with the flange plate against the End face of the end flange 14 is pressed so that the connection space 32 or the lamp housing are sealed off from the mast 10.

Innerhalb des Anschlußraumes 32f befinden sich Anschlußklemmen, an denen die Kabel angeschlossen werden und von denen eine elektrische Leitungsführung zu den Komponenten der Mastleuchte führt.Within the connection space 32f there are connection terminals to which the cables are connected and from which an electrical lead leads to the components of the mast light.
