Description

Die vorliegende Erfindung betrifft eine Leuchte mit Abhängevorrichtungen zum Abhängen und Abklappen eines im Leuchtengehäuse eingesetzten Rasters, wobei die Abhängevorrichtungen jeweils umfassen ein mit dem Leuchtengehäuse verbundenes Verankerungsteil, das eine Öffnung aufweist, durch die ein mit einem Halteelement verbundener Träger hindurch geschoben werden kann, sowie eine Auflageeinheit und eine Blattfeder mit einem freien und einem mit dem Verankerungsteil verbundenen Ende, die sich im wesentlichen in Einschubrichtung des Trägers erstreckt und quer zur Einschubrichtung des Trägers federt, den Träger, der zwischen einer oberen Stellung, in der er mittels einer Rastnase mit dem Verankerungsteil verrastet ist, und einer unteren Stellung, in der er mit einem Haltevorsprung auf der Auflageeinheit des Verankerungsteils aufliegt, in dem Verankerungsteil auf- und abbewegbar ist, und der zum Abnehmen des Rasters aus dem Verankerungsteil aushängbar ist, und das jeweils mit dem Längsreflektor des Leuchtenrasters verbundene Halteelement mit Lagerlöchern, in die die unteren Enden des Trägers um eine horizontale Achse schwenkbar eingesetzt sind.The present invention relates to a lamp Hanging devices for hanging and folding an im Luminaire housing used grid, the Suspension devices each include one with the Luminaire housing connected anchoring part, the one Has opening through which a holding element connected carrier can be pushed through, as well a support unit and a leaf spring with a free and one end connected to the anchoring part, which is in the extends essentially in the direction of insertion of the carrier and springs transversely to the direction of insertion of the carrier, the between an upper position, in which he by means of a Latch is locked to the anchoring part, and one lower position, in which he has a retaining projection on the Support unit of the anchoring part rests in the Anchoring part is movable up and down, and the Removing the grid from the anchoring part unhooked is, and that with the longitudinal reflector of the Luminaire grid connected holding element with bearing holes, in the lower ends of the beam around a horizontal axis are pivotally used.

Aus der DE 37 39 075 ist eine Leuchte mit einer Abhängevorrichtung der vorgenannten Art bekannt. Bei dieser bekannten Abhängevorrichtung ist das Halteelement an seinem unteren Ende mit dem Längsreflektor des Leuchtenrasters fest verbunden und an seinem oberen Ende von einem umgebogenen Bereich des Längsreflektors übergriffen. Aufgrund dieser Befestigung an beiden Enden wird der Längsreflektor einer Spannung ausgesetzt, die zu einer Verbiegung des Rasters führen kann. Desweiteren befindet sich bei der bekannten Leuchte mit Abhängevorrichtung das freie Ende der Blattfeder an der Unterseite des Verankerungsteils. Aufgrund dieser Befestigungsweise besteht die Möglichkeit, den Träger nicht nur gehäuseseitig an der Blattfeder vorbei in die dafür vorgesehene Öffnung, sondern auch wandseitig hinter die Blattfeder einzuschieben. Durch dieses fehlerhafte Einschieben kann sowohl das Verankerungsteil, als auch das Raster zerstört werden. Diese Befestigungsweise der Blattfeder weist zudem den Nachteil auf, daß während des Einschiebens des Trägers ein Druck in Richtung auf die Gehäuseseitenwand auf die Blattfeder ausgeübt werden muß, um den Haltevorsprung an der Auflageeinheit vorbeischieben zu können.DE 37 39 075 is a lamp with a Suspension device of the aforementioned type known. At this known suspension device is the holding element on his lower end with the longitudinal reflector of the luminaire grid connected and bent over at its upper end by a Area of the longitudinal reflector overlapped. Based on these The longitudinal reflector becomes one at both ends Exposed to tension that causes the grid to bend can lead. Furthermore, is in the known Light with hanging device the free end of the leaf spring at the bottom of the anchoring part. Based on these It is possible to attach the carrier, not the carrier only on the housing side past the leaf spring in the for it provided opening, but also behind the wall Insert leaf spring. Because of this faulty Both the anchoring part and the can be inserted Grid will be destroyed. This way of fastening the Leaf spring also has the disadvantage that during the Inserting the carrier a pressure towards the Housing side wall must be exerted on the leaf spring in order push the retaining projection past the support unit can.

Das der vorliegenden Erfindung zugrunde liegende Problem ist die Schaffung einer Leuchte mit einer Abhängevorrichtung für das Raster der vorgenannten Art, die die genannten Nachteile nicht aufweist.The problem underlying the present invention is the creation of a lamp with a suspension device for the grid of the aforementioned type, the disadvantages mentioned does not have.

Dies wird gemäß dem kennzeichnenden Merkmal des Hauptanspruchs dadurch erreicht, daß das obere Ende der Blattfeder ihr freies Ende ist. Diese Befestigungsweise der Blattfeder bietet den Vorteil, daß der Träger nicht hinter die Blattfeder geschoben werden kann und somit auch die Gefahr der Zerstörung von Verankerungsteil und Raster während des Einschiebens des Trägers verringert wird. Desweiteren muß kein zusätzlicher Druck auf die Blattfeder ausgeübt werden, um den Haltevorsprung an der Auflageeinheit vorbeischieben zu können, da der Träger selbst die Blattfeder beim Einschieben zur Seite drückt.This is according to the characteristic feature of the Main claim achieved in that the upper end of the Leaf spring is its free end. This way of fastening the Leaf spring has the advantage that the carrier is not behind the leaf spring can be pushed and thus the Risk of the anchoring part and grid being destroyed is reduced during insertion of the carrier. Furthermore, there is no additional pressure on the leaf spring are exercised around the retaining projection on the support unit to be able to push past, because the carrier itself Presses the leaf spring to the side when inserting it.

Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung ist der obere Teil des Trägers leicht in Richtung auf das Gehäuseinnere abgewinkelt, wobei sich hier auch die Rastnase und der Haltevorsprung auf der Seite des Trägers befinden, die der Gehäuseinnenseite zugewandt ist. Durch diese Anordnung ruht auch bei schweren Rastern der Haltevorsprung im abgehängten Zustand sicher auf der Auflageeinheit. Zugleich steht durch das Abwinkeln des Trägers zum Gehäuseinneren mehr Raum im Eckbereich zur Verfügung, so daß die elektrischen Zuleitungen dort problemlos untergebracht werden können.According to a preferred embodiment of the present Invention is the top of the carrier slightly towards angled to the inside of the case, with the Latch and the retaining projection on the side of the carrier are located, which faces the inside of the housing. By this arrangement rests even with heavy grids Retaining tab in the suspended state securely on the Support unit. At the same time stands by angling the Carrier to the interior of the housing more space in the corner area Available so the electrical leads there can be easily accommodated.

Vorzugsweise weist das Halteelement zwei zueinander parallele, an ihren oberen Rändern miteinander verbundene ebene Abschnitte auf, mit deren Hilfe es so auf das untere Ende des Längsreflektors geschoben werden kann, daß es diesen wie eine Klammer umgreift. Da keine weitere Verbindung des Längsreflektors mit dem Halteelement besteht, wird der Längsreflektor auch keiner Spannung ausgesetzt, wodurch Deformationen des Rasters vermieden werden. The holding element preferably has two to one another parallel, interconnected at their upper edges level sections, with the help of which it is so on the lower End of the longitudinal reflector can be pushed that it grips it like a bracket. Since no more There is a connection between the longitudinal reflector and the holding element, the longitudinal reflector is not exposed to any tension, thereby avoiding deformations of the grid.

In der oberen Einbauposition des Rasters gemäß Fig. 2 nimmt der Träger 5 eine Lage ein, in der sein oberer langer Schenkel 10 vertikal liegt und parallel zur Seitenwand des Leuchtengehäuses 1 läuft, wobei das obere Ende des oberen langen Schenkels 10 sich etwa im Eckbereich des Leuchtengehäuses 1 kurz unterhalb der Gehäusedecke und etwa in gleicher Höhe mit dem oberen Ende des Längsreflektors 4 befindet. Der Träger weist an seinem oberen langen Schenkel 10 eine Rastnase 11 und einen Haltevorsprung 12 auf.Structure and function of the suspension device according to one Embodiment of the invention is below With reference to FIGS. 2 to 5 described in more detail. The Carrier 5 is made in one piece from sheet metal by bending and punching manufactured. According to the top installation position of the grid Fig. 2, the carrier 5 occupies a position in which its upper long leg 10 is vertical and parallel to Side wall of the lamp housing 1 runs, the upper End of the upper long leg 10 is approximately in the corner area of the luminaire housing 1 just below the housing ceiling and about the same height as the top of the Longitudinal reflector 4 is located. The wearer points to his upper long leg 10 a latch 11 and one Holding projection 12 on.

Der Haltevorsprung 12 ist ein durch Stanzen und Biegen gebildeter ebener Lappen und die Rastnase 12 ist durch Einstanzen von zwei zueinander parallelen Schlitzen und Ausbiegen des hierdurch gebildeten Stegs im spitzen Winkel in ungefähr V-förmige Gestalt hergestellt.The holding protrusion 12 is one by punching and bending formed flat rag and the locking lug 12 is through Punching two parallel slots and Bend the web thus formed at an acute angle made in an approximately V-shape.

Wie man aus Fig. 2 erkennen kann, weist der Träger 5 im unteren Drittel, im Anschluß an die Rastnase 11, einen kurzen, unter einem spitzen Winkel zum oberen langen Schenkel 10 abgewinkelten Abschnitt 13 auf, der an der gleichen Seite aus der Ebene des Schenkels 10 herausragt wie die Rastnase 11 und der Haltevorsprung 12. Daran schließt sich ein parallel zu dem oberen langen Schenkel 10 verlaufender Abschnitt 14 an, der in einem schräg abgewinkelten unteren Schenkel 15 endet. Wie aus Fig. 2 ersichtlich ist, nimmt dieser untere Schenkel 15 in etwa die gleiche Winkelstellung gegenüber dem oberen langen Schenkel 10 ein wie der kurze Abschnitt 13. Der perspektivischen Ansicht in Fig. 5b läßt sich entnehmen, daß der untere Schenkel 15 zu beiden Seiten über den relativ schmalen streifenförmigen Träger 5 hinausragt und eine ungefähr rechteckige Form aufweist. An seinen seitlichen Enden sind zwei miteinander fluchtende Zapfen 16 angeformt.As can be seen from Fig. 2, the carrier 5 has in lower third, following the locking lug 11, one short, at an acute angle to the upper long one Leg 10 angled section 13 on the same side protrudes from the plane of the leg 10 as the locking lug 11 and the retaining projection 12. This closes parallel to the upper long leg 10 extending section 14 at an oblique angled lower leg 15 ends. As from Fig. 2 can be seen, this lower leg 15 takes approximately same angular position with respect to the upper long leg 10 a like the short section 13. The perspective View in Fig. 5b can be seen that the lower Leg 15 on both sides over the relatively narrow strip-shaped carrier 5 protrudes and approximately has a rectangular shape. Are on its side ends two pins 16 aligned with one another are formed.

Die Halteklammer 6 ist ebenfalls einstückig aus Blech durch Stanzen und Biegen hergestellt. Sie umfaßt zwei etwa rechteckige, eng aneinanderliegende ebene Abschnitte 17 und 18, die an den Außenseiten ihrer oberen Ränder durch zwei streifenförmige haarnadelförmig umgebogene Laschen 19 miteinander verbunden sind (Fig. 5b). An dem Abschnitt 18 sind seitlich und im rechten Winkel zu diesem ausgerichtet Lagerschenkel 20 mit Lagerlöchern 21 angeformt, in die die beiden Zapfen 16 des Trägers 5 eingesetzt werden können. Die Halteklammer 6 kann so auf das nach oben umgebogenen Endstück 7 der Rinne, die von den Längsreflektoren 4 gebildet wird, geschoben werden, daß an jeder Seite dieses Endstücks 7 einer der rechteckigen Abschnitte 17 und 18 anliegt. Der Abschnitt 18 weist seitlich an seiner Unterseite zwei schräg abgewinkelte Zungen 22 auf, die als Führung während des Aufsteckens der Halteklammer 6 auf das Endstück 7 dienen. Zudem erhöhen die Zungen 22 die Klemmwirkung der Halteklammer 6, weil sie in einem spitzen Winkel von der Fläche 18 nach außen weggebogen sind. In den Fig. 5c bis Fig. 5e ist eine andere Ausführungsform der vorliegenden Erfindung abgebildet, bei der anstelle zweier getrennter Zungen 22 eine durchgehende Zunge 22 an dem Abschnitt 18 angebracht ist. The retaining clip 6 is also made in one piece from sheet metal Stamping and bending. It comprises two rectangular, closely spaced flat sections 17 and 18 on the outside of their upper edges by two Strip-shaped tabs 19 bent over in a hairpin shape are interconnected (Fig. 5b). At section 18 are aligned laterally and at right angles to it Bearing legs 20 formed with bearing holes 21, in which the two pins 16 of the carrier 5 can be used. The Retaining clip 6 can thus be bent upwards End piece 7 of the channel, which is from the longitudinal reflectors 4th is formed, that on each side of this End piece 7 of one of the rectangular sections 17 and 18th is present. The section 18 has the side of it Underside of two obliquely angled tongues 22, which as Guide while attaching the bracket 6 on the Serve tail 7. In addition, the tongues 22 increase the Clamping effect of the retaining clip 6 because they are in a pointed Angles are bent away from the surface 18 to the outside. In the 5c to 5e is another embodiment of the mapped present invention, in which instead of two separate tongues 22 a continuous tongue 22 on the Section 18 is attached.

Bei der Befestigung und Abhängung des Rasters wirkt der Träger 5 mit dem Verankerungsteil 8 zusammen. Letzteres ist in Fig. 4 a bis c für sich dargestellt. Dieses Verankerungsteil 8 ist ein Stanz- und Biegeteil aus Blech und besteht im unteren Teil aus einem vertikalen Schenkel 23, der jeweils endseitig oben um etwa 180° umgebogen ist, so daß zwei sich nach unten erstreckende Lappen 24 entstehen, die wie man in Fig. 2 erkennt, durch eine Ausnehmung 9 im Seitenteil des Gehäuses 1 hindurchgreifen. Diese nach unten umgebogenen Lappen 24 sind im unteren Bereich zu Haken einwärts gebogen, die sich in das Blech des Gehäuses 1 der Leuchte krallen. Der vertikale Schenkel 23 und die umgebogenen Lappen 24 sind federnd miteinander verbunden, so daß sich die umgebogenen Lappen 24 mit den Haken über das Blech der Seitenteile des Gehäuses 1 schieben lassen, um das Verankerungsteil 8 am Blech des Gehäuses 1 zu befestigen. Den vertikalen Schenkel 23 verbinden zwei vertikal nach oben verlaufende Streifen 25 mit einem etwas schmaleren Lappen 26, der unter einem Winkel von etwa 60° in das Gehäuse 1 hineinragt. An dem unteren Rand des Lappens 26 ist ein ankerförmiges Halteteil 27 befestigt, daß ebenfalls durch die Ausnehmung 9 des Gehäuses 1 hindurchgreift, und mit zwei äußeren Haken von außen an dem Blech des Gehäuses 1 anliegt. An dem winklig in das Gehäuse 1 hineinragenden Lappen 26 sind zwei nach unten und hinten zur Gehäuseseitenwand abgewinkelte Streifen 28 angeschlossen, die an ihrem unteren Ende durch einen schmalen Querstreifen 29 miteinander verbunden sind. Von diesem Querstreifen 29 geht eine nach oben ragende zungenförmige Blattfeder 30 aus, deren freier Endbereich schräg abgewinkelt ist.The is effective when attaching and suspending the grid Carrier 5 together with the anchoring part 8. The latter is 4 a to c for themselves. This Anchoring part 8 is a stamped and bent part made of sheet metal and consists of a vertical leg in the lower part 23, which is bent at the end at the top by approximately 180 °, so that two tabs 24 extending downward arise, as can be seen in Fig. 2, by a Reach recess 9 in the side part of housing 1. These flaps 24 bent downward are in the lower one Area bent into hooks that fit into the sheet metal of the Claw housing 1 of the lamp. The vertical leg 23 and the bent tabs 24 are resilient to one another connected so that the bent tabs 24 with the Push the hook over the sheet metal of the side parts of the housing 1 leave to the anchoring part 8 on the sheet of the housing 1 fasten. The vertical leg 23 connect two vertically upward stripes 25 with a little narrower tab 26 which is at an angle of about 60 ° in the housing 1 protrudes. At the lower edge of tab 26 is an anchor-shaped holding part 27 attached that also reaches through the recess 9 of the housing 1, and with two outer hooks on the outside of the sheet metal of the housing 1 is present. On the protruding into the housing 1 at an angle Tabs 26 are two down and back to Angled strips 28 connected to the housing side wall, at the lower end by a narrow horizontal stripe 29 are connected. From this horizontal stripe 29 a tongue-shaped leaf spring 30 protrudes upwards, whose free end area is angled at an angle.

In der oberen Stellung des Trägers 5 (siehe Fig. 1) befindet sich die Rastnase 11 oberhalb des winklig in das Gehäuse 1 hineinragenden Lappens 26. Dabei drückt die Blattfeder 30 den oberen langen Schenkel 10 des Trägers 5 gegen den Lappen 26 des Verankerungteils 8. Zum Abhängen des Rasters kann nun die Rastnase 11 des Trägers 5 gegen die Federspannung der Blattfeder 30 an dem Lappen 26 des Verankerungsteils 8 vorbei heruntergezogen werden. Sobald die Rastnase 11 an dem Lappen 26 vorbeigeführt wurde, läßt sich der Träger 5 leichter herunterziehen, bis der Haltevorsprung 12 an dem Lappen 26 anschlägt, so daß ein weiteres Herunterziehen des Trägers 5 blockiert ist. Es ist dann die in Fig. 3 dargestellte Position erreicht. Nun kann der rechte Träger 5 von dem rechten Verankerungsteil 8 gelöst werden, indem, wie dies in Fig. 3 durch den Pfeil 1. angedeutet ist, der Träger 5 ein Stück angehoben und dann außerdem, wie dies durch den Pfeil 2. angedeutet ist, einwärts geschwenkt wird. Der Träger 5 wird dadurch von dem Verankerungsteil 8 gelöst, da der Haltevorsprung 12 über den Lappen 26 des Verankerungsteils 8 gehoben wird. Nachdem der rechte Träger 5 gelöst ist, kann das Raster abgehängt werden, wobei der linke Träger 5 auf dem linken Verankerungsteil 8 festhängt und die Längsreflektoren 4 um die durch die Zapfen 16 des linken Trägers 5 und die Lagerlöcher 21 der Halteklammer 6 gegebene horizontale Achse schwenken. Die um 90° geschwenkte Endlage des Rasters ist in Fig. 3 durch strichpunktierte Linien dargestellt.In the upper position of the carrier 5 (see Fig. 1) the locking lug 11 above the angled into the housing 1 protruding flap 26. The leaf spring 30 presses the upper long leg 10 of the carrier 5 against the rag 26 of the anchoring part 8. Now you can hang the grid the locking lug 11 of the carrier 5 against the spring tension of the Leaf spring 30 on the tab 26 of the anchoring part 8 be pulled down by. As soon as the latch 11 on the Lobe 26 has been passed, the carrier 5th pull down easier until the retaining projection 12 on the Tab 26 strikes, so that a further pull down Carrier 5 is blocked. It is then that in FIG. 3 shown position reached. Now the right carrier 5 can be released from the right anchoring part 8 by how this is indicated in Fig. 3 by the arrow 1., the carrier 5 raised a bit and then, as indicated by the Arrow 2. is indicated, is pivoted inwards. The Carrier 5 is thereby released from the anchoring part 8, since the holding projection 12 over the tab 26 of the Anchoring part 8 is raised. After the right carrier 5 is solved, the grid can be suspended, the left carrier 5 hangs on the left anchoring part 8 and the longitudinal reflectors 4 around by the pin 16 of the left carrier 5 and the bearing holes 21 of the holding bracket 6 swivel the given horizontal axis. The one swiveled by 90 ° End position of the grid is in Fig. 3 by dash-dotted lines Lines shown.

Der dem Träger 5 in Funktion und Aufbau ähnelnde Träger 31 (Fig. 7) ist ebenfalls einstückig aus Blech durch Biegen und Stanzen hergestellt. Der Träger 31 weist einen dem unteren Schenkel 15 entsprechenden schräg nach oben (siehe Fig. 7a) abgewinkelten unteren Schenkel 32 auf, der wie dieser, wie aus der Draufsicht in Fig. 7b ersichtlich ist, ungefähr rechteckig geformt und an seinen seitlichen Enden mit zwei Zapfen 33 versehen ist. An den unteren Schenkel 32 schließt sich ein vertikaler Abschnitt 34 an (siehe Fig. 7a), der länger als der vertikale Abschnitt 14 des Trägers 5 ausgeführt ist und eine schräge, der Rastnase 12 entsprechende, Rastnase 35 aufweist, wobei die Rastnase 35 seitlich nach unten aus der Ebene des vertikalen Abschnitts 34 herausragt. Der an den vertikalen Abschnitt 34 angrenzende obere lange Schenkel 36 des Trägers 31 ist gegenüber dem vertikalen Abschnitt um einen Winkel von ungefähr 10° entgegengesetzt zu dem unteren Schenkel 32 (nach unten in Fig. 7a) geneigt. In seinem oberen Endbereich ist auf der Seite, auf der auch die Rastnase 35 angebracht ist, ein, dem Haltevorsprung 12 entsprechender, Haltevorsprung 37 herausgebogen. In Fig. 7c ist der Träger 31 in Verbindung mit der in den Fig. 5c bis 5e dargestellten Ausführungsform der Halteklammer 6 abgebildet.Structure and function of the suspension device according to one Another embodiment of the invention is as follows with reference to FIGS. 6 to 9 in more detail described. The carrier 5 in function and structure similar carrier 31 (Fig. 7) is also made in one piece Sheet made by bending and punching. The carrier 31 has a slant corresponding to the lower leg 15 lower leg 32 angled upward (see FIG. 7a) on, like this one, as seen from the top view in Fig. 7b can be seen, approximately rectangular in shape and on its lateral ends is provided with two pins 33. To the lower leg 32 closes a vertical section 34 (see Fig. 7a), which is longer than the vertical Section 14 of the carrier 5 is executed and an oblique, the catch 12 has corresponding catch 35, wherein the latch 35 laterally downward from the plane of the vertical section 34 protrudes. The one on the vertical Section 34 adjacent upper long legs 36 of the wearer 31 is at an angle to the vertical section of approximately 10 ° opposite the lower leg 32 (down in Fig. 7a). In its upper end area is on the side on which the latch 35 is attached is a, corresponding to the holding projection 12, Holding projection 37 bent out. 7c is the carrier 31 in connection with that shown in FIGS. 5c to 5e Embodiment of the retaining clip 6 shown.

In den Fig. 6 a bis d ist das mit dem Träger 31 zusammenwirkende, dem Verankerungsteil 8 ähnelnde Verankerungsteil 38 abgebildet. Dieses Verankerungsteil 38 ist ein Stanz- und Biegeteil aus Blech und besteht im unteren Teil aus einem vertikalen Schenkel 39, der jeweils endseitig oben um etwa 180° umgebogen ist, so daß zwei sich nach unten erstreckende Lappen 40 entstehen, die entsprechend den Lappen 24, durch eine Ausnehmung 9 im Seitenteil des Gehäuses 1 hindurchgreifen können. Wie bei dem Verankerungsteil 8 sind auch bei dem Verankerungsteil 38 der Schenkel 39 und die umgebogenen Lappen 40 federnd miteinander verbunden, so daß sich die umgebogenen Lappen 40 mit den Haken über das Blech der Seitenteile des Gehäuses 1 schieben lassen, um das Verankerungsteil 38 am Blech des Gehäuses 1 zu befestigen. An den vertikalen Schenkel 39 schließen sich zwei schmalere vertikal nach oben verlaufende Streifen 41 an, zwischen denen sich eine Blattfeder 42 befindet, deren freier Endbereich spitz abgewinkelt ist und die nur am unteren Ende mit dem vertikalen Schenkel 39 verbunden ist. Die Streifen 41 sind oben rechtwinklig nach rechts in Fig. 6a umgebogen und von diesem horizontalen Schenkel aus erneut in einem Winkel von ungefähr 100° fast vertikal nach unten hin abgebogen. An dem oberen Ende dieses annähernd vertikalen Schenkels 43 ist zwischen den beiden vertikalen Streifen 41 eine kurze Anlagekante 44 angestanzt, die unter einem Winkel von etwa 15° zur Vertikalen nach oben hin ragt. Aus Fig. 6c ist ersichtlich, daß die an dem annähernd vertikalen Schenkel 43 angestanzte Anlagekante 44 in ihrer seitlichen Ausdehnung genau der Blattfeder 42 entspricht. Außerdem kann der Fig. 6c entnommen werden, daß der annähernd vertikale Schenkel 43 unterhalb der Anlagekante 44 eine geschlossene, nicht in Streifen aufgeteilte, Fläche bildet.6 a to d, this is with the carrier 31 cooperating, similar to the anchoring part 8 Anchoring part 38 shown. This anchoring part 38 is a stamped and bent part made of sheet metal and consists of lower part of a vertical leg 39, each is bent at the top end by about 180 °, so that two downward extending tabs 40 arise corresponding to the tab 24, through a recess 9 in Can reach through part of the housing 1. As in the anchoring part 8 are also in the anchoring part 38 the leg 39 and the bent tabs 40 are resilient joined together so that the bent tabs 40 with the hooks over the sheet metal of the side parts of the housing 1 slide to the anchoring part 38 on the sheet of the Attach housing 1. On the vertical leg 39 close two narrower vertically upward Strip 41 on, between which a leaf spring 42nd is located, the free end portion is angled sharply and only at the lower end with the vertical leg 39 connected is. The strips 41 are rectangular at the top bent to the right in Fig. 6a and from this horizontal Thighs out again at an angle of approximately 100 ° almost bent vertically downwards. At the top of this approximately vertical leg 43 is between the two vertical strips 41 punched a short contact edge 44, which at an angle of about 15 ° to the vertical protrudes. From Fig. 6c it can be seen that the on approximately vertical leg 43 stamped contact edge 44th in its lateral extent exactly the leaf spring 42 corresponds. In addition, Fig. 6c can be seen that the approximately vertical leg 43 below the Contact edge 44 a closed, not in strips divided, area forms.

Das Zusammenwirken des Trägers 31 und des Verankerungteils 38 entspricht dem des Trägers 5 mit dem Verankerungsteil 8. In der oberen Stellung des Trägers 31 (siehe Fig. 8 und Fig. 9a) befindet sich die Rastnase 35 oberhalb der Anlagekante 44. Dabei liegt der abgewinkelte Endbereich der Blattfeder 42 an dem vertikalen Abschnitt 34 des Trägers 31 an, so daß dieser gegen die Anlagekante 44 des Verankerungteils 38 gedrückt wird. Zum Abhängen des Rasters kann nun die Rastnase 35 des Trägers 31 gegen die Federspannung der Blattfeder 42 an der Anlagekante 44 des Verankerungsteils 38 vorbei heruntergezogen werden. Sobald die Rastnase 35 an der Anlagekante 44 vorbeigeführt wurde, läßt sich der Träger 31 leichter herunterziehen, bis der Haltevorsprung 37 an der Anlagekante 44 anschlägt, so daß ein weiteres Herunterziehen des Trägers 31 blockiert ist. Es ist dann die in Fig. 9b dargestellte Position erreicht. Nun kann der rechte Träger 31 von dem rechten Verankerungsteil 38 gelöst werden, indem, wie dies in Fig. 9b durch den Pfeil 1. angedeutet ist, der Träger 5 ein Stück angehoben und dann außerdem, wie dies durch den Pfeil 2. angedeutet ist, mit seinem oberen langen Schenkel 36 in Richtung auf die Gehäusewand geschwenkt wird. Der Träger 31 wird dadurch von dem Verankerungsteil 38 gelöst, da der Haltevorsprung 37 über die Anlagekante 44 des Verankerungsteils 38 gehoben wird. Nachdem der rechte Träger 31 gelöst ist, kann das Raster abgehängt werden, wobei der linke Träger 31 auf dem linken Verankerungsteil 38 festhängt und die Längsreflektoren 4 um die durch die Zapfen 33 des linken Trägers 31 und die Lagerlöcher 21 der Halteklammer 6 gegebene horizontale Achse schwenken. Die um 90° geschwenkte Endlage des Rasters ist in Fig. 10 dargestellt.The interaction of the carrier 31 and the anchoring part 38 corresponds to that of the carrier 5 with the anchoring part 8. In the upper position of the carrier 31 (see Fig. 8 and Fig. 9a), the locking lug 35 is located above the contact edge 44. The angled end region of the leaf spring lies here 42 on the vertical section 34 of the carrier 31 so that this against the contact edge 44 of the anchoring part 38 is pressed. For hanging the grid you can now use the Latch 35 of the carrier 31 against the spring tension of the Leaf spring 42 on the contact edge 44 of the anchoring part 38 be pulled down by. As soon as the latch 35 on the Carrier edge 44 has been passed, the carrier 31 pull down easier until the retaining projection 37 on the Contact edge 44 stops, so that another pull down of the carrier 31 is blocked. It is then that in Fig. 9b shown position reached. Now the right carrier can 31 can be released from the right anchoring part 38 by as indicated in Fig. 9b by the arrow 1., the Carrier 5 raised a bit and then also like this is indicated by the arrow 2. with its upper long Leg 36 is pivoted in the direction of the housing wall. The carrier 31 is thereby of the anchoring part 38th solved because the holding projection 37 over the contact edge 44 of the Anchoring part 38 is raised. After the right carrier 31 is solved, the grid can be suspended, the left carrier 31 hangs on the left anchoring part 38 and the longitudinal reflectors 4 around by the pin 33 of the left carrier 31 and the bearing holes 21 of the holding bracket 6 swivel the given horizontal axis. The one swiveled by 90 ° End position of the grid is shown in Fig. 10.
