Description

Die Abdeckung (Raster, Wanne) der Lichtaustrittsöffnung einer Leuchte ist vorzugsweise abschwenkbar an einer Längskante des Leuchtengehäuses gelagert, wobei zusätzlich ein vollständiges Aushängen in einem bestimmten, unkritischen Winkelbereich möglich ist. Diese einfachste Halterung setzt jedoch einen ausreichenden Schwenkbereich innerhalb des Leuchtengehäuses voraus, der nicht immer gegeben ist. In solchen Fällen hat man sich mit Halterungen beholfen, die mit Haltefedern arbeiten, die sich bei abgezogener Abdeckung in einem Teil des Leuchtengehäuses verhaken. Zum einseitigen Abschwenken oder vollständigen Abnehmen der Abdeckung können dann die Federn manuell von dem Leuchtengehäuse gelöst werden.The cover (grid, trough) of the light exit opening of a lamp is preferably pivotally mounted on a longitudinal edge of the lamp housing, it also being possible to completely unhook it in a certain, uncritical angular range. However, this simplest bracket requires a sufficient swivel range within the luminaire housing, which is not always the case. In such cases, brackets have been used that work with retaining springs that get caught in a part of the lamp housing when the cover is removed. The springs can then be manually detached from the lamp housing for one-sided pivoting or complete removal of the cover.

Die Erfindung betrifft die Halterung einer solchen absenkbaren Leuchtenabdeckung gemäß Oberbegriff von Anspruch 1. Ihr liegt die Aufgabe zugrunde, eine solche Halterung so zu verbessern, daß sich die Abdeckung nach Lösen der Haltefedern auf einer Längsseite der Leuchte abschwenken läßt. Die erfindungsgemäße Lösung dieser Aufgabe ist bei einer Halterung der eingangs genannten Art in Anspruch 1 gekennzeichnet.The invention relates to the holder of such a lowerable lamp cover according to the preamble of claim 1. It is based on the object of improving such a holder so that the cover can be pivoted away on a long side of the lamp after loosening the retaining springs. The achievement of this object is characterized in a holder of the type mentioned in claim 1.

Die Erfindung zeichnet sich durch eine besonders einfache Gestaltung des Randbereichs der Abdeckung.aus; trotzdem ist eine einwandfreie Halterung gewährleistet und ein versehentliches Aushängen praktisch ausgeschlossen.The invention is characterized by a particularly simple design of the edge region of the cover. nevertheless, a perfect mounting is guaranteed and accidental unhinging is practically impossible.

Bei einer in den Unteransprüchen gekennzeichneten Ausführungsform liegt die Tragfeder federnd an blanken Schnittkanten der Abdeckung und des Federhalters, so daß zwischen beiden stets eine einwandfreie elektrische Verbindung gewährleistet ist, selbst wenn diese Teile aus beschichtetem Blech bestehen. Dabei ist der Federhalter vorzugsweise aus nichtrostendem Material, insbesondere aus feuerverzinktem Blech, und mit dem Leuchtengehäuse mechanisch so verbunden, daß dadurch zugleich eine sichere elektrische Verbindung gewährleistet ist.In one embodiment characterized in the subclaims, the suspension spring resiliently bare Cut edges of the cover and the spring holder, so that a perfect electrical connection is always guaranteed between the two, even if these parts consist of coated sheet metal. The spring holder is preferably made of rustproof material, in particular of hot-dip galvanized sheet metal, and mechanically connected to the lamp housing in such a way that a secure electrical connection is thereby ensured at the same time.

Durch diese Eigenschaften unterscheidet sich die Erfindung auch vorteilhaft vom Stand der Technik (DE-OS 26 55 252, 26 07 129): Dort ist zwar ein Abschwenken der abgezogenen Abdeckung möglich; jedoch ist die Lagerung der Federn an der Abdeckung aufwendig und ein versehentliches Aushängen der Abdeckung nicht ausgeschlossen. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.These properties also advantageously distinguish the invention from the prior art (DE-OS 26 55 252, 26 07 129): it is possible to pivot the removed cover off there; however, the storage of the springs on the cover is complex and accidental unhooking of the cover is not excluded. Further advantageous embodiments of the invention are characterized in the subclaims.

Bei der Ausführungsform nach den FIG 1 bis 3 ist der Federhalter 2 mit seitlichen Stützwänden 22 und einer oberen Stützwand 24 an der Seitenwand 11 und/oder der Gehäusedecke 12 des Leuchtengehäuses 1 befestigt, wobei die seitlichen Stützwände 22 an ihren unteren Enden abgewinkelte Steckarme 221 aufweisen, die durch zugeordnete Schlitze 111 in der Seitenwand 11 des Leuchtengehäuses hindurchgreifen. Die seitlichen Stützwände 22 des Federhalters 2 sind gegenüber dessen Deckwand 20 etwa um die Dicke der Tragfeder 4 versetzt, so daß ein Führungsraum 23 zwischen der Deckwand 20 des Federhalters 2 und der Seitenwand 11 des Leuchtengehäuses 1 entsteht, der von unten durch einen Führungsschlitz 231 parallel zur Seitenwand 11 zugänglich ist und der seitlich von den Seitenwänden 21 des Federhalters 2 begrenzt ist; der Abstand b dieser Seitenwände (FIG 2) ist kleiner als der Abstand B zwischen den Vorsprüngen 43 der Tragfeder 4.In the embodiment according to FIGS. 1 to 3, the spring holder 2 is fastened with side support walls 22 and an upper support wall 24 to the side wall 11 and / or the housing cover 12 of the lamp housing 1, the side support walls 22 having angled plug-in arms 221 at their lower ends that reach through assigned slots 111 in the side wall 11 of the lamp housing. The lateral support walls 22 of the spring holder 2 are offset relative to its top wall 20 by approximately the thickness of the suspension spring 4, so that a guide space 23 is formed between the top wall 20 of the spring holder 2 and the side wall 11 of the lamp housing 1, which is parallel from below through a guide slot 231 is accessible to the side wall 11 and is laterally limited by the side walls 21 of the spring holder 2; the distance b of these side walls (FIG 2) is smaller than that Distance B between the projections 43 of the suspension spring 4.

Die in der Lichtaustrittsöffnung 13 des Leuchtengehäuses 1 angeordnete Leuchtenabdeckung 3 ist hier als Raster mit einer Längswand 30 dargestellt, die unten einen V-förmigen, nach oben offenen Randbereich mit einem Längsrand 31 hat. Letzterer ist im Bereich der Lagerarme 411 der Tragfeder 4 über diese darübergebogen und bildet so Lagerstücke 311, in denen die Lagerarme 411 drehbar sind und die aufeinander zu gerichtete Eintrittsöffnungen 3110 haben: Daher lassen sich die Tragfedern bei herabgezogener Leuchtenabdeckung 3 von ihr lösen, indem die Tragarme 41 der Tragfeder gegeneinander gedrückt werden. Dies ist jedoch schon nach einer kleinen Drehung der Längswand 30 (in FIG 1 in Pfeilrichtung) nach unten nicht mehr möglich, da dann der Sperrlappen 313 (vgl. FIG 2) zwischen die Tragarme 41 der Tragfeder tritt und damit deren Bewegungsspielraum begrenzt. Die Leuchtenabdeckung 3 ist daher bereits beim Herunterschwenken und insbesondere im abgeschwenkten Zustand gegen versehentliches Lösen von der Tragfeder gesichert.The lamp cover 3 arranged in the light exit opening 13 of the lamp housing 1 is shown here as a grid with a longitudinal wall 30 which has a V-shaped, upwardly open edge region with a longitudinal edge 31 at the bottom. The latter is bent over it in the area of the bearing arms 411 of the suspension spring 4 and thus forms bearing pieces 311 in which the bearing arms 411 can be rotated and have the inlet openings 3110 directed towards one another Support arms 41 of the suspension spring are pressed against each other. However, this is no longer possible even after a small rotation of the longitudinal wall 30 (in the direction of the arrow in FIG. 1), since the locking tab 313 (see FIG. 2) then enters between the support arms 41 of the suspension spring and thus limits their freedom of movement. The lamp cover 3 is therefore already secured against inadvertent detachment from the suspension spring when it is swiveled down and in particular in the swiveled-out state.

Auf der der Eintrittsöffnung 3110 jedes Lagerstückes 311 gegenüberliegenden Seite bildet ein Stück des Längsrandes 31 einen Erdungslappen 312, der soweit nach innen umgebogen ist, daß die freie Stirnseite der Lagerarme 411 der Tragfeder federnd gegen seine Schnittkante 3121 drückt: Dadurch ist eine Masseverbindung zwischen Tragfeder und Leuchtenabdeckung 3 hergestellt, die auch dann gewährleistet ist, wenn die Längswand 30 der Leuchtenabdeckung 3 aus vorbeschichtetem Blech besteht.On the side opposite the inlet opening 3110 of each bearing piece 311, a piece of the longitudinal edge 31 forms an earthing tab 312 which is bent inwards so far that the free end face of the bearing arms 411 of the suspension spring resiliently presses against its cutting edge 3121: this creates a ground connection between the suspension spring and Luminaire cover 3 is produced, which is also guaranteed when the longitudinal wall 30 of the luminaire cover 3 consists of pre-coated sheet metal.

Zwischen dem oberen Ende der Tragarme 41 der M förmigen Tragfeder 4 und ihrem V-förmigen Verbindungsstück 42 liegt je ein Vorsprung 43, der von einem Tragschenkel 432 und einem etwa rechtwinklig dazu verlaufenden Oberschenkel 431 gebildet wird, wobei der nach unten gerichtete Tragschenkel 432 einen spitzen Winkel α mit der Ebene der Lichtaustrittsöffnung einschließt. Dieser Winkel ist einerseits so groß, daß dieser Tragschenkel 432 auf der Tragkante 211 am oberen Ende der Seitenwände 21 des Führungsraumes 23 mit genügend Reibungswiderstand aufliegt, um die Leuchtenabdeckung 3 in der Lichtaustrittsöffnung 13 zu halten (FIG 2, gezeichnete Position der Tragfeder 4). Andererseits ermöglicht die Neigung des Tragschenkels 432 ein Herabziehen der Abdeckung nach unten, wobei die Vorsprünge 43 der Tragfeder 4 gegeneinander gedrückt werden, bis sie schließlich in den Führungsraum 23 eintreten und beim weiteren Herabziehen an den Seitenwänden 21 des Führungsraumes 23 entlanggleiten und hierbei ebenfalls für einen sicheren Massekontakt sorgen (Position der Tragfeder 4' in FIG 2).Between the upper end of the support arms 41 of the M-shaped suspension spring 4 and its V-shaped connecting piece 42 there is a projection 43, which is formed by a support leg 432 and a thigh 431 running approximately at right angles thereto, the downward-pointing support leg 432 forming an acute angle α with the plane of the light exit opening. On the one hand, this angle is so large that this supporting leg 432 rests on the supporting edge 211 at the upper end of the side walls 21 of the guide space 23 with sufficient friction resistance to hold the lamp cover 3 in the light exit opening 13 (FIG. 2, drawn position of the supporting spring 4). On the other hand, the inclination of the support leg 432 enables the cover to be pulled down, the projections 43 of the support spring 4 being pressed against one another until they finally enter the guide space 23 and slide along the side walls 21 of the guide space 23 as they are pulled down, and also for one ensure a safe ground contact (position of the suspension spring 4 'in FIG 2).

Der Bewegungsspielraum der Tragfeder 4 nach unten ist durch Haken 201 begrenzt, die in den Führungsraum 23 ragen und an denen sich die Tragfeder 4 verhakt (Position der mit 4'' bezeichneten Feder in FIG 2). In dieser Position drücken dann die Oberschenkel 431 der Vorsprünge 43 gegen die Unterkante 212 der Seitenwände 21 des Federhalters 2 und sichern damit eine Masseverbindung. Dabei ist die in FIG 2 dargestellte Abmessungsrelation vorausgesetzt und auch/daß die Tragarme 41 der Tragfeder -4 in der in FIG 2 dargestellten Position mit Vorspannung nach außen gegen die Erdungslappen 312 drücken.The range of motion of the suspension spring 4 downwards is limited by hooks 201 which protrude into the guide space 23 and on which the suspension spring 4 hooks (position of the spring denoted by 4 ″ in FIG. 2). In this position, the thighs 431 of the projections 43 then press against the lower edge 212 of the side walls 21 of the spring holder 2 and thus secure a ground connection. The dimensional relationship shown in FIG. 2 is assumed and also / that the support arms 41 of the support spring -4 in the position shown in FIG. 2 press against the earth tab 312 with a preload.

Je nach Abmessungen ist es mitunter fertigungstechnisch schwierig, die Lagerstücke durch Umbiegen des V-förmigen Längsrandes herzustellen. Eine Alternative hierzu ist in den FIG 4 bis 6 gezeigt, in denen ein Lagerformteil 5, vorzugsweise aus Kunststoff, vorgesehen ist, das sowohl zwei im Abstand voneinander liegende Lagerstücke 511 als auch einen zwischen ihnen liegenden Sperrlappen 512 aufweist. Dieses Lagerformteil 5 ist auf den freien Schenkel des U-förmig ausgebildeten Längsrandes 31.13 aufgesteckt, der hierzu eine etwas zurückgesetzte Kante 31.13 und zwei Aussparungen 31.11 zur Aufnahme der Sperrhaken 521 von Federschenkeln 52 des Lagerformteiles hat. Jeder Federschenkel 52 verläuft in einem der Dicke des Blechs der Abdeckung entsprechenden Abstand von einem Hauptschenkel 51 des Lagerformteiles 5.Depending on the dimensions, it is sometimes difficult to manufacture the bearing pieces by bending the V-shaped longitudinal edge. An alternative to this is shown in FIGS. 4 to 6, in which a molded bearing part 5, preferably made of plastic, is provided, which both has two spaced-apart bearing pieces 511 and a locking tab 512 located between them. This shaped bearing part 5 is placed on the free leg of the U-shaped longitudinal edge 31.13, which for this purpose has a somewhat recessed edge 31.13 and two recesses 31.11 for receiving the locking hooks 521 of spring legs 52 of the shaped bearing part. Each spring leg 52 runs at a distance corresponding to the thickness of the sheet metal of the cover from a main leg 51 of the shaped bearing part 5.

Die Kante 31.13 des Längsrandes 31.1 der Abdeckung 3.1 ist gegenüber der Randkante dieses freien Schenkels etwa um die Bauhöhe der Lagerstücke 511 zurückversetzt, so daß die Enden der Lagerarme 41'1 federnd auf den Schnittkanten 31.12 der benachbarten Erdungslappen 312.1 aufliegen.The edge 31.13 of the longitudinal edge 31.1 of the cover 3.1 is set back from the edge of this free leg approximately by the height of the bearing pieces 511, so that the ends of the bearing arms 41'1 resiliently rest on the cutting edges 31.12 of the adjacent earthing tabs 312.1.

Bei dieser Ausführungsform der Erfindung braucht somit lediglich ein Randstreifen der Abdeckung mit Ausklinkungen zur Aufnahme des Lagerformteiles ausgerüstet zu werden. Die fertigungstechnisch schwierigeren Gestaltungselemente sind dagegen in das Lagerformteil verlegt, das aber als Spritzteil ebenfalls leicht zu fertigen ist.In this embodiment of the invention, therefore, only one edge strip of the cover needs to be equipped with notches for receiving the molded bearing part. The design elements, which are more difficult in terms of production technology, on the other hand, are moved into the molded bearing part, which, however, is also easy to manufacture as an injection molded part.

Bei der Ausführungsform nach den FIG 7 bis 10 ist je Tragfeder 4.2 je ein Federhalter 2.1 aus verzinktem Blech vorgesehen, der mittels einer Stützwand 24.1 an der Gehäusedecke 12 befestigt ist. Dieser Federhalter umschließt mit seiner Deckwand 20.1 und seitlich von dieser umgewinkelten Führungswänden 22.1 (FIG 9) den Führungsraum 23.1, der seitlich durch Seitenwände 21.1 begrenzt ist und in den von der Deckwand 20.1 her Haken 201 .1 hineinragen.In the embodiment according to FIGS. 7 to 10, a spring holder 2.1 made of galvanized sheet metal is provided for each support spring 4.2 and is fastened to the housing cover 12 by means of a support wall 24.1. This spring holder encloses with its top wall 20.1 and laterally angled guide walls 22.1 (FIG. 9) the guide space 23.1, which is laterally delimited by side walls 21.1 and protrude into the hook 201 .1 from the top wall 20.1.

Die beiden freien Enden der Tragarme 41.2 jeder Tragfeder 4.2 sind doppelt abgewinkelt, nämlich einmal innerhalb einer Ebene parallel zur Lichtaustrittsöffnung 13 und ferner in einer Ebene senkrecht zu dieser Lichtaustrittsöffnung: Parallel zur Ebene der Lichtaustrittsöffnung und zum Längsrand 31.2 der Abdeckung 3.2 liegt jeweils ein freies Endstück 410.2; in derselben Ebene ist ferner der zu diesem Endstück 410.2 senkrechte Lagerarm 411.2 (FIG 11) angeordnet. Dieser steht außerdem etwa senkrecht auf der Seitenwandung 11 des Leuchtengehäuses 1.The two free ends of the support arms 41.2 of each suspension spring 4.2 are angled twice, namely once within a plane parallel to the light exit opening 13 and also in a plane perpendicular to this light exit opening: parallel to the plane of the light exit opening and to the longitudinal edge 31.2 of the cover 3.2 there is a free end piece in each case 410.2; The bearing arm 411.2 (FIG. 11) perpendicular to this end piece 410.2 is also arranged in the same plane. This is also approximately perpendicular to the side wall 11 of the lamp housing 1.

Der Längsrand 31.2 der Abdeckung 3.2 hat je Tragfeder 4.2 eine schlitzförmige Aussparung 31.20, die parallel zu diesem Längsrand und zur Lichtaustrittsöffnung verläuft (FIG 10). Durch diese Aussparung greifen die Tragarme 41.2 jeder Tragfeder mit ihrem Lagerarm 411.2 und dem daran anschließenden Endstück 410.2 in den nach oben offenen V-förmigen Randbereich der Abdeckung (FIG 11). Wenn die Abdeckung 3.2 in die Lichtaustrittsöffnung 13 des Leuchtengehäuses 1 eingeschwenkt ist - wie in FIG 11 gestrichelt dargestellt - ruht die Oberkante 31.21 der Aussparung 31.20 auf den Lagerarmen 411.2 jeder Tragfeder 4.2. Ist dagegen die Abdeckung herausgeschwenkt - wie in FIG 11 dargestellt - dann liegt sie mit der Randkante 31.23 ihres Längsrandes 31.2 auf den Lagerarmen 411.2 auf.The longitudinal edge 31.2 of the cover 3.2 has a slot-shaped recess 31.20 for each supporting spring 4.2, which runs parallel to this longitudinal edge and to the light exit opening (FIG. 10). Through this recess, the support arms 41.2 of each support spring with their bearing arm 411.2 and the adjoining end piece 410.2 engage in the upwardly open V-shaped edge region of the cover (FIG. 11). When the cover 3.2 is pivoted into the light exit opening 13 of the lamp housing 1 - as shown in broken lines in FIG. 11 - the upper edge 31.21 of the recess 31.20 rests on the bearing arms 411.2 of each suspension spring 4.2. If, on the other hand, the cover is pivoted out - as shown in FIG. 11 - then it lies on the bearing arms 411.2 with the edge 31.23 of its longitudinal edge 31.2.

Zum Aushängen der Abdeckung müssen die Tragarme 41.2 jeder Tragfeder 4.2 so weit gegeneinander gedrückt werden, bis beide Endstücke 410.2 durch die schlitzförmige Aussparung 31.20 hindurchtreten können. Bei entsprechender Länge dieser Endstücke ist daher ein zufälliges, unbeab- . sichtigtes Aushängen der Abdeckung ausgeschlossen.To unhook the cover, the support arms 41.2 of each support spring 4.2 must be pressed against one another until both end pieces 410.2 can pass through the slot-shaped recess 31.20. With the appropriate length of these end pieces, a random, unintended. Visible hanging of the cover excluded.

Die Länge der Aussparung 31.20 ist etwas kleiner als die Breite b des Führungsraumes 23.1 des Federhalters 2.1 (FIG 8): Damit ist gewährleistet, daß die Enden der Tragarme 41.2 stets mit Vorspannung an den seitlichen Schnittkanten 31.22 dieser Aussparung 31.20 anliegen und für eine elektrische Verbindung sorgen.The length of the recess 31.20 is slightly smaller than that Width b of the guide space 23.1 of the spring holder 2.1 (FIG. 8): This ensures that the ends of the support arms 41.2 always bear against the lateral cutting edges 31.22 of this cutout 31.20 and provide an electrical connection.
