Abstract

A light fitting with a transparent cover (2) pivotally affixed therein by means of hinges, the light fitting (1) having longitudinal grooves (1) which are open above and have a free inner limb (111) adjacent to the cover (2), and the cover (2) having an edge limb (21), which partially overlaps the longitudinal groove (11) on the outside. In such an arrangement, which is known from German Utility Model 7,729,796, the fulcrum of the hinges is situated outside the light fitting, and is correspondingly visible with the associated apertures. The invention enables the fulcrum to be moved into the light fitting in conjunction with full pivotability of the cover. For this purpose, each hinge consists of a pillow block (31), a connector (32) with a C-shaped cross-section and a bearing part (321) and locking arm (322), and of a receptacle (33), which enables a detachable connection between the locking arm (322) of the connector (32) and the cover (2). <IMAGE>

Description

Die Erfindung betrifft einen Leuchtenrahmen mit darin schwenkbar gelagerter lichtdurchlässiger Abdeckung gemäß Oberbegriff von Anspruch 1; unter'Leuchtenrahmen ist dabei die Begrenzung der Lichtaustrittsöffnung einer Leuchte und unter Abdeckung jede lichtlenkende oder abschirmende Einrichtung, beispielsweise ein Raster, zu verstehen.The invention relates to a light frame with a translucent cover pivotally mounted therein according to the preamble of claim 1; ' Luminaire frame is to be understood to mean the limitation of the light exit opening of a luminaire and to cover any light-directing or shielding device, for example a grid.

Bei einer aus dem DE-Gbm 77 29 796 bekannten Anordnung dieser Art liegt der Drehpunkt eines zweiteiligen Scharniers außerhalb des Leuchtenrahmens; dadurch ist ein Ab-, schwenken der Abdeckung trotz des die Längsrinne außen zum Teil überlappenden Randschenkels dieser Abdeckung möglich. Hierbei stören jedoch die sichtbaren Durchbrüche und die durch diese nach außen ragenden Scharnierteile.In an arrangement of this type known from DE-Gbm 77 29 796, the fulcrum of a two-part hinge lies outside the lamp frame; this enables the cover to be swiveled off and swiveled in spite of the outer edge of this cover partially overlapping the longitudinal groove on the outside. However, the visible openings and the hinge parts protruding through them interfere with this.

Aus der DE-PS 2 743 189 ist andererseits ein Leuchtenrahmen mit schwenkbar gelagerter Abdeckung bekannt, bei der die.einstückigen Scharniere vollständig innerhalb des Leuchtenrahmens liegen; trotzdem ist die Abdeckung vollständig abschwenkbar und gegen unbeabsichtigtes Aushängen gesichert. Diese Art der Verbindung ist jedoch nicht anwendbar, wenn ein Randschenkel der Abdeckung die Längsrinne des Rahmens teilweise überlappt, weil dann die Abdeckung nicht mehr einhängbar wäre.From DE-PS 2 743 189, on the other hand, a luminaire frame with a pivotally mounted cover is known, in which the one-piece hinges lie completely within the luminaire frame; nevertheless, the cover can be swung out completely and secured against unintentional unhooking. However, this type of connection cannot be used if an edge limb of the cover partially overlaps the longitudinal groove of the frame, because the cover would then no longer be able to be attached.

Der Erfindung liegt die Aufgabe zugrunde, das Scharnier für einen Leuchtenrahmen gemäß Oberbegriff von Anspruch 1 so auszubilden, daß es einerseits innerhalb des Leuchtenrahmens liegt, ein vollständiges und gesichertes Abschwenken aber ebenso möglich ist wie eine einfache Montage und Demontage der Abdeckung.The invention has for its object the hinge for a lamp frame according to the preamble of claim 1 to be designed in such a way that it lies on the one hand within the luminaire frame, but that complete and secure pivoting is just as possible as simple assembly and disassembly of the cover.

Die Lösung dieser Aufgabe bei einem Leuchtenrahmen gemäß Oberbegriff von Anspruch 1 ist durch die in dessen Kennzeichen angegebenen Merkmale charakterisiert.The solution to this problem in a luminaire frame according to the preamble of claim 1 is characterized by the features specified in its characteristics.

Bei der Erfindung sorgt einerseits der Lagerbock für einen ausreichend großen Abstand zwischen Drehpunkt des Scharniers und dem den Rahmen überdeckenden Randschenkel der Abdeckung, so daß diese ungehindert abgeschwenkt werden kann; die lösbare Verbindung zwischen dem Arretierarm des Verbinders und der mit der Abdeckung verbundenen Aufnahme ist andererseits Voraussetzung für das Ein- und Aushängen der Abdeckung.In the invention, on the one hand, the bearing block provides a sufficiently large distance between the pivot point of the hinge and the edge leg of the cover covering the frame, so that it can be pivoted freely; the detachable connection between the locking arm of the connector and the receptacle connected to the cover is, on the other hand, a prerequisite for attaching and detaching the cover.

Lagerbock und Aufnahme können in konventioneller Weise, z.B. durch Nieten, mit dem Leuchtenrahmen bzw. der Abdeckung verbunden sein: vorteilhafter sind jedoch an sich bekannte Rastverbindungen, vor allem, wenn diese Teile aus Kunststoff bestehen.The bearing block and holder can be mounted in a conventional by rivets, be connected to the lamp frame or the cover: However, known snap-in connections are more advantageous, especially if these parts are made of plastic.

Als C-förmiger Verbinder kann ein entsprechend gebogener Blechstreifen dienen; vorzugsweise findet jedoch ein Biegeteil aus Draht Verwendung.A correspondingly bent sheet metal strip can serve as a C-shaped connector; however, a bent part made of wire is preferably used.

wobei in den FIG 3, 4, 6 und 7 der Verbinder gestrichelt angedeutet ist.3, 4, 6 and 7 of the connector is indicated by dashed lines.

In FIG 1 ist die nach oben offene Längsrinne eines Leuchtenrahmens 1 mit 11 bezeichnet und wird von einem freien Innenschenkel 111 und einem Außenschenkel 112 begrenzt; dieser Außenschenkel ist beispielsweise Teil eines nach unten offenen, trogförmigen Leuchtengehäuses, das eine nach unten offene, rechteckige Lichtaustrittsöffnung hat, die von zwei parallel zueinander verlaufenden Längsrinnen und zwei quer dazu stehenden Stirnseiten begrenzt ist.In FIG 1, the upwardly open longitudinal channel of a lamp frame 1 is designated 11 and is delimited by a free inner leg 111 and an outer leg 112; this outer leg is, for example, part of a trough-shaped luminaire housing which is open at the bottom and has a rectangular light outlet opening which is open at the bottom and is delimited by two longitudinal channels which run parallel to one another and two end faces which run transversely thereto.

In der so begrenzten Lichtaustrittsöffnung ist eine Abdeckung 2 in Form eines Rasters vorgesehen, von dem in FIG 1 nur ein Längsträger 22 und ein Randschenkel 21 dargestellt ist, der die Längsrinne 11 zum Teil überlappt.In the light exit opening limited in this way, a cover 2 is provided in the form of a grid, of which only one side member 22 and one edge leg 21 is shown in FIG. 1, which partially overlaps the longitudinal channel 11.

Leuchtenrahmen 1 und Abdeckung 2 sind durch zwei im Abstand voneinander angeordnete Scharniere gemäß FIG 1 miteinander verbunden. Jedes Scharnier besteht aus einem in der Längsrinne 11 des Leuchtenrahmens befestigten Lagerbock 31, einer mit der Abdeckung 2 verbundenen Aufnahme 33 (FIG 6 bis 10) und einem Verbinder 32 (FIG 1 und 2).Luminaire frame 1 and cover 2 are connected to one another by two hinges arranged at a distance from one another as shown in FIG. Each hinge consists of a bearing block 31 fastened in the longitudinal groove 11 of the lamp frame, a receptacle 33 connected to the cover 2 (FIGS. 6 to 10) and a connector 32 (FIGS. 1 and 2).

Der Lagerbock 31 gemäß FIG 1 und FIG 3 bis 5 ist ein Formteil aus Kunststoff, das mit seinem Unterteil in die Längsrinne 11 paßt und mit Steckschlitzen 312 auf dem Innenschenkel 111 sitzt; letzterer hat eine Ausnehmung 1111.The bearing block 31 according to FIG 1 and 3 to 5 is a molded part made of plastic, which fits with its lower part in the longitudinal groove 11 and sits with plug slots 312 on the inner leg 111; the latter has a recess 1111.

Der Lagerbock 31 weist in der Mitte eine federnde-Rastzunge 313 mit einer Rastnase 3131 an deren Ende auf (FIG 1, 5): Beim Einsetzen des Lagerbockes in die Längsrinne 11 wird diese Rastzunge 313 von dem Innenschenkel 111 zunächst zurückgedrückt bis die Rastnase 3131 in die Ausnehmung 1111 des Innenschenkels 111 einschnappt und so den Lagerbock 31 in der Längsrinne festhält.The bearing block 31 has a resilient latching tongue 313 in the middle with a latching lug 3131 at its end (FIG. 1, 5): When the bearing bracket is inserted into the longitudinal channel 11, this latching tongue 313 is first pushed back by the inner leg 111 until the latching lug 3131 in the recess 1111 of the inner leg 111 snaps in and thus holds the bearing block 31 in the longitudinal groove.

Der Lagerbock 31 hat ferner zwei Lager 311 (FIG 1 und 5) für die Lagerteile 321, 321' des Verbinders 32; zu diesen Lagern 311 führt ein Einführungsschlitz 310 für das Lagerteil 321 des Verbinders 32, dessen Eintrittsöffnung kleiner als das Lagerteil ist, wobei eine Begrenzungswand 3101 federnd ausgebildet ist.The bearing block 31 also has two bearings 311 (FIGS. 1 and 5) for the bearing parts 321, 321 'of the connector 32; to these bearings 311 there is an insertion slot 310 for the bearing part 321 of the connector 32, the inlet opening of which is smaller than the bearing part, a boundary wall 3101 being resilient.

Die in den FIG 1 und 6 bis 10 dargestellte Aufnahme 33 ist ebenfalls ein Formteil aus Kunststoff: Zwischen zwei Rastverbindern 333, 334 (FIG 6, 7) verläuft ein U-förmiger Steg 330, von dessen Mitte die Arretierzunge 232 nach unten absteht. Diese hat eine schräg verlaufende Anlauffläche 3321, eine Rastnase 3322 und einen Hebel 3323.The receptacle 33 shown in FIGS. 1 and 6 to 10 is also a molded part made of plastic: between two Locking connectors 333, 334 (FIG. 6, 7) run a U-shaped web 330, from the center of which the locking tongue 232 projects downward. This has an obliquely running contact surface 3321, a detent 3322 and a lever 3323.

Die Rastverbinder 333 und 334 bestehen jeweils aus einem Steckschlitz 3341 für den Längsträger 22 der Abdeckung 2 sowie einem diesen Längsträger übergreifenden Federhaken 3342 (FIG 10). Diese Rastverbinder 333 und 334 haben von dem Steg 330 einen derartigen Abstand, daß zwischen diesem Steg und dem Längsträger 22 eine Tasche 331 (FIG 1 und-7 bis 9) entsteht, in die gerade das Querstück 3221 mit den beiden Arretierarmen 322, 3221 des Verbinders 32 paßt. Die Rastnase 3322 der Aufnahme 33 übergreift dabei gerade das Querstück 3221 des Verbinders 32 und hält diesen dadurch in der Tasche 331 fest (FIG 1).The latching connectors 333 and 334 each consist of a plug-in slot 3341 for the side member 22 of the cover 2 and a spring hook 3342 overlapping this side member (FIG. 10). These snap-in connectors 333 and 334 are at a distance from the web 330 such that a pocket 331 (FIGS. 1 and 7 to 9) is formed between this web and the longitudinal member 22, into which the crosspiece 3221 with the two locking arms 322, 322 1 is being made of the connector 32 fits. The locking lug 3322 of the receptacle 33 just overlaps the cross piece 3221 of the connector 32 and thereby holds it in the pocket 331 (FIG. 1).

Der Verbinder 32 (FIG 1 und 2) ist ein Biegeteil aus Draht mit zwei zu einer Mittelebene M symmetrischen, durch ein Querstück 3221 verbundenen C-förmigen Abschitten (FIG 1), von denen jeder ein Lagerteil 321, 321' und einen Arretierarm 322, 322' hat. Zur Montage wird jeder Lagerbock mit der Längsrinne 11 des Leuchtenrahmens 1 und jede Aufnahme 33 mit dem Längsträger 22 der Abdekkung 2 verbunden und sodann der Verbinder 32 mit seinen Lagerteilen 321, 321' durch die Einführungsschlitze 310 in die Lager 311 des Lagerbockes 31 eingeführt. Danach werden die Arretierarme 322, 322' des Verbinders 32 in die Tasche 331 zwischen Längsträger 22 und Aufnahme 33 eingesteckt, bis sein Querstück 3221 hinter der Rastnase 3322 eingerastet ist. Zum Lösen der Abdeckung 2 braucht lediglich der Hebel 3323 in FIG 1 etwas nach rechts gedrückt zu werden: Dann gibt die Rastnase 3322 das Querstück 3221 des Verbinders 32 frei, so daß dieser aus der Tasche 331 gezogen werden kann.The connector 32 (FIGS. 1 and 2) is a bent part made of wire with two C-shaped sections (FIG. 1) symmetrical to a central plane M and connected by a crosspiece 3221, each of which has a bearing part 321, 321 'and a locking arm 322, 322 '. For assembly, each bearing block is connected to the longitudinal channel 11 of the lamp frame 1 and each receptacle 33 to the longitudinal member 22 of the cover 2, and then the connector 32 with its bearing parts 321, 321 'is inserted through the insertion slots 310 into the bearing 311 of the bearing block 31. Then the locking arms 322, 322 'of the connector 32 are inserted into the pocket 331 between the longitudinal beam 22 and the receptacle 33 until its cross piece 3221 is locked behind the locking lug 3322. To release the cover 2, only the lever 3323 in FIG. 1 needs to be pushed a little to the right: Then the detent 3322 releases the cross piece 3221 of the connector 32 so that it can be pulled out of the pocket 331.

Der Abstand des Lagers 311 des Lagerbockes 31 von der äußeren Kante 211 des Randschenkels 21 der Abdeckung 2 ist so groß gewählt, daß sich dieser Randschenkel 21 beim Absenken der Abdeckung 2 frei um die Längsrinne 11 herumbewegen kann, wobei die C-förmigen Abschnitte des Verbinders 32 so groß bemessen sein müssen, daß sie die Längsrinne 11 und gegebenenfalls Teile des Lagerbockes 31 übergreifen. Damit der Verbinder 32 möglichst klein gehalten werden kann, hat der Lagerbock 31 Einschnitte 314 (FIG 3 und 4) in die sich der Verbinder 32 beim Abschwenken der Abdeckung 2 hineinbewegen kann.The distance of the bearing 311 of the bearing block 31 from the outer edge 211 of the edge of the leg 21 of the cover 2 is chosen so large that this edge leg 21 is free to move around about the longitudinal groove 1 1 when lowering the cover 2, whereby the C-shaped portions of the Connector 32 must be sized so that they overlap the longitudinal channel 11 and possibly parts of the bearing block 31. So that the connector 32 can be kept as small as possible, the bearing block 31 has incisions 314 (FIGS. 3 and 4) into which the connector 32 can move when the cover 2 is pivoted away.
