Abstract

The lamp (1) has a housing (2), which has a front opening (5) with a rim (6), and has side walls (3) extending into a wall opening (18). The lamp can be fastened in the wall opening by fixing elements (10), which can move along guide rails (9) on the side walls, between the front (4) and rear (7) of the housing. The guide rails slope rearwards behind the frontal cross-section of the housing, and the fixing elements have surfaces to enable them to grip the wall from the rear. When near the rim, the elements project over the frontal cross-section, and when distant from the rim they withdraw behind it. <IMAGE>

Description

Die Erfindung betrifft eine Leuchte zum Einbau in einen Plattendurchbruch oder einen Wandhohlraum.The invention relates to a luminaire for installation in a panel opening or a wall cavity.

Aus der GB-A-20 47 869 ist eine Leuchte zum Einbau in eine abgehängte Decke bekannt, die an ihrer Frontseite einen ihren Frontquerschnitt seitlich überragenden Rand und davon ausgehend zur Rückseite sich hinter den Frontquerschnitt neigende Seitenwänden aufweist. An der Außenseite der Seitenwände sind Blechstreifen angeordnet, die längs den Seitenwänden verschieblich sind. Zum Einbau in eine abgehängte Decke wird die Leuchte von der Raumseite her in den Freiraum zwischen abgehängter Decke und Raumdecke bis zum Anschlag des Randes an der Decke eingeschoben. Danach werden die seitlichen Blechstreifen mit Hilfe von zur Innenseite des Gehäuse hervorstehenden Schrauben verschoben bis die Blechstreifen mit ihrer Stirnfläche an die Rückseite der abgehängten Decke stoßen und die Lampe auf der Decke abstützen. In dieser Stellung werden die Blechstreifen mit Hilfe der Schrauben von der Innenseite des Gehäuses arretiert, so daß die Leuchte über die Blechstreifen auf der abgehängten Decke aufsteht und die Platte der abgehängten Decke zwischen dem Rand und den Blechstreifen eingeklemmt ist. So läßt sich die Leuchte einfach in Plattendurchbrüche einbauen. Dieses Prinzip versagt aber z.B. bei zu dicken Platten, die nicht von den Blechstreifen hintergriffen werden können.From GB-A-20 47 869 is a luminaire for installation in a suspended Blanket known, the one on the front Front cross-section laterally projecting edge and starting from it side walls sloping to the rear behind the front cross section having. There are metal strips on the outside of the side walls arranged, which can be moved along the side walls are. The luminaire from the room side in the space between the suspended ceiling and the ceiling is pushed in as far as the edge of the ceiling. Then the side metal strips with the help by screws protruding to the inside of the housing until the sheet metal strips with their end face on the Bump the back of the false ceiling and the lamp on the Support the ceiling. In this position, the metal strips locked with the screws from the inside of the housing, so that the lamp over the metal strips on the suspended Ceiling stands up and the slab of the suspended ceiling is jammed between the edge and the metal strips. So the light can be easily installed in plate openings. This principle fails e.g. if the plates are too thick, the cannot be touched by the metal strips.

Aus der FR-A-13 42 965 ist eine Leuchte zum losen Auflegen auf die Oberseite einer abgehängten Decke bekannt, bei der Winkelstücke entlang zur Rückseite nach innen geneigter Gehäusewände bewegbar sind, um die Leuchte in geeigneter Höhe an der Deckenplatte zu positionieren. Hierfür werden die Winkelstücke zur Rückseite des Gehäuses verschoben und die Leuchte einschließlich Frontrand in den Plattendurchbruch eingeschoben bis die Frontseite mit der Platte etwa fluchtet. Daraufhin werden die Winkelstücke über von der Innenseite des Gehäuses zugängliche Schrauben bis zur Anlage an der Rückseite der Platte verschoben, so daß die Leuchte relativ zur Platte in der gewünschten Höhe auf der Platte aufliegt. Dieser Mechanismus versagt allerdings wenn die Leuchte z.B. seitlich hängend in eine Seitenwand eingebaut werden soll. From FR-A-13 42 965 there is a light for hanging up loosely the top of a false ceiling known at the corner pieces along housing walls inclined inwards towards the rear are movable to the lamp at a suitable height on the ceiling plate to position. For this, the contra-angles are used Moved back of the housing and including the lamp Inserted the front edge into the panel opening until the Front is approximately flush with the plate. Then the Contra-angle pieces accessible from the inside of the housing Screws moved until they touch the back of the plate, so that the lamp relative to the plate in the desired Height rests on the plate. However, this mechanism fails if the lamp e.g. hanging sideways in a side wall to be installed.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte der eingangs genannten Gattung dahingehend zu verbessern, daß sie trotz einfacher Konstruktion einfach und sicher in verschiedenartige Platten oder Wände einzubauen und zu befestigen ist.The invention has for its object a lamp of the beginning to improve the genus mentioned so that it in spite of the simple construction simple and safe in different types Plates or walls must be installed and fastened.

Diese Aufgabe wird erfindungsgemäß gelöst mit einer Leuchte zum wahlweisen Einbau in einen Plattendurchbruch oder einen Wandhohlraum, mit einem Gehäuse, dessen Seitenwände sich durch den Plattendurchbruch hindurch oder in den Wandhohlraum hinein erstrecken und an einer Frontseite des Gehäuses eine Gehäuseöffnung begrenzen, wobei die Leuchte wenigstens bereichsweise einen den Frontquerschnitt des Gehäuses überragenden Rand aufweist, der an dem Rand des Plattendurchbruchs oder an der Außenseite der Wand anlegbar ist, und das Gehäuse mit an den Seitenwänden angeordneten Verankerungselementen befestigbar ist, wobei die Verankerungselemente jeweils längs einer an einer Seitenwand zwischen Frontseite und Gehäuserückseite vorgesehenen, sich zur Gehäuserückseite neigenden Bewegungsbahn verschiebbar sind und den Frontquerschnitt in einer dem Rand nahen Stellung überragen, und in einer dem Rand entfernten Stellung dahinter zurücktreten,
wobei die Verankerungselemente beim Einbau in einen Plattendurchbruch die Platte mit einer Anschlagflanke hintergreifen und sich beim Einbau in einen Wandhohlraum, in auf die dem Rand nahe Stellung zubewegt, an den Wandungen des Hohlraums verspreizen und die Leuchte mit Gegenhalt des Randes daran verklemmen.This object is achieved according to the invention with a lamp for optional installation in a panel opening or a wall cavity, with a housing whose side walls extend through the panel opening or into the wall cavity and delimit a housing opening on a front side of the housing, the lamp at least in some areas has an edge projecting beyond the front cross-section of the housing, which can be placed on the edge of the panel opening or on the outside of the wall, and the housing can be fastened with anchoring elements arranged on the side walls, the anchoring elements each being provided along a side wall between the front and rear side of the housing , can be shifted towards the rear of the housing and traverse the front cross-section in a position close to the edge, and step back in a position distant from the edge,
wherein the anchoring elements reach behind the plate with a stop flank when installed in a plate opening and, when installed in a wall cavity, move towards the position close to the edge, spread on the walls of the cavity and clamp the lamp against the edge.

Damit kann die Leuchte auch in einem Wandhohlraum befestigt werden. Zum Einbau der Leuchte werden die Verankerungselemente in die dem Rand entfernte Stellung geschoben, so daß sie hinter den Frontquerschnitt zurücktreten und die Leuchte bis zum Anschlag des Randes an der Wand in den Wandhohlraum eingebracht werden kann. Danach werden die Verankerungselemente auf den Rand zubewegt bis sie seitlich in Kontakt mit den Wandungen des Hohlraums sind und sich daran verspreizen. In Folge der Bewegung von der Rückseite zur Frontseite und der Verspreizung wird die Leuchte dadurch mit Gegenhalt gegen den an der Wand anliegenden Rand verklemmt. Dies gewährleistet eine sichere und vor allen Dingen einfache Befestigung der Leuchte in einem Wandhohlraum. Beim Verschieben der Verankerungselemente kann die Leuchte in dem Wandhohlraum in die gewünschte Position ausgerichtet werden. So that the lamp can also be fixed in a wall cavity become. The anchoring elements are used to install the luminaire pushed into the position distant from the edge, so that it is behind withdraw the front cross-section and the lamp as far as it will go of the edge on the wall into the wall cavity can be. Then the anchoring elements on the Edge until it comes into lateral contact with the walls of the Are hollow and spread out on it. As a result of the movement from the back to the front and the spreading becomes the luminaire thus counteracts against the wall Edge jammed. This ensures a safe and up front simple fixation of the lamp in a wall cavity. When moving the anchoring elements, the Luminaire in the wall cavity aligned in the desired position become.

Vorzugsweise sind die Bewegungsbahnen als Gewindebolzen ausgebildet und die Verankerungselemente weisen ebenfalls Gewinde auf, die in Eingriff mit dem jeweiligen Gewindebolzen sind. Dadurch können die Verankerungselemente durch Drehen des Gewindebolzens längs der Bewegungsbahn verschoben werden. Damit ist die Bewegung der Verankerungselemente exakt steuerbar und die Verankerungselemente können wirksam gegen die Rückseite einer dünnen Wand oder die Wandung eines Hohlraumes festgezogen werden.The movement paths are preferably designed as threaded bolts and the anchoring elements also have threads on, which are in engagement with the respective threaded bolt. Thereby the anchorage elements can be turned by turning the threaded bolt be moved along the path of movement. So that is the movement of the anchoring elements can be precisely controlled and the Anchoring elements can be effective against the back of a thin wall or the wall of a cavity can be tightened.

Günstigerweise kann der Kopf des Gewindebolzens an der Frontseite des Gehäuses angeordnet sein und von dieser bedienbar sein. Dadurch kann der Gewindebolzen von der Frontseite des Gehäuses gedreht werden, so daß die Verankerungselemente entlang der Bewegungsbahn verschoben werden. Damit sind Ein- und Ausbau der Leuchte vereinfacht.Conveniently, the head of the threaded bolt can be on the front of the housing can be arranged and operated by this be. This allows the threaded bolt to be removed from the front of the housing be rotated so that the anchoring elements along the trajectory are shifted. This means installation and removal the lamp simplified.

Günstigerweise können die Verankerungselemente mit einer Seite von außen an dem Gehäuse anliegen. Dadurch sind die Anschlagelemente unverdrehbar und längsverschieblich an dem Gehäuse gelagert. Über die Anlage an dem Gehäuse können die auf die Verankerungselemente einwirkenden Kräfte an das Gehäuse übertragen werden. Dies ist besonders günstig, wenn die Verankerungselemente von innen an den Wandungen eines Hohlraumes verspannt werden. Dies beugt insbesondere dem Verbiegen der Bewegungsbahn bzw. der Gewindebolzen vor.Conveniently, the anchoring elements with one side contact the housing from the outside. This makes the stop elements non-rotatably and longitudinally displaceably mounted on the housing. The system can be attached to the anchoring elements via the system forces acting on the housing become. This is particularly beneficial if the anchoring elements braced from the inside on the walls of a cavity become. This particularly prevents the trajectory from bending or the threaded bolt.

Besonders vorteilhaft sind die Verankerungselemente als dreiekkige Platten ausgebildet, die mit einer Dreieckseite von außen an dem Gehäuse anliegen. Mit der Dreiecksform können die Verankerungselemente den Ecken einer Wandöffnung angepaßt werden, so daß die Wandecken von hinten voll hintergriffen werden.The anchoring elements are particularly advantageous as triangular Plates formed with a triangular side from the outside rest on the housing. With the triangular shape, the anchoring elements can be adapted to the corners of a wall opening, so that the wall corners are fully gripped from behind.

Günstigerweise können die Seitenwände des Gehäuses zur Gehäuserückseite hinter den Frontquerschnitt des Gehäuses geneigt sein. Durch diese sich zur Gehäuserückseite verjüngende Gehäuseform kann die Leuchte sehr einfach in die Wandöffnung eingesetzt werden. Dabei kann die Neigung der Seitenwände der Neigung der Bewegungsbahnen angepaßt sein.Conveniently, the side walls of the housing can go to the rear of the housing inclined behind the front cross section of the housing be. Through this housing shape tapering towards the rear of the housing the lamp can be easily inserted into the wall opening become. In doing so, the slope of the side walls of the slope be adapted to the trajectories.

In besonderer Weise können die Bewegungsbahnen parallel zu zwischen zwei benachbarten Seitenwänden gebildeten abgeflachten Gehäusekanten angeordnet sein und die Verankerungselemente jeweils mit einer Seite an einer abgeflachten Gehäusekante verschieblich anliegen. An den abgeflachten Gehäusekanten sind die Verankerungselemente geführt und stützen sich beim Verspannen in einem Hohlraum an ihnen ab.In a special way, the trajectories can be parallel to between flattened two adjacent side walls formed Housing edges can be arranged and the anchoring elements each with one side slidable on a flattened housing edge issue. On the flattened case edges are the Anchoring elements are guided and supported when bracing in a cavity on them.

Als Variante der Erfindung entspricht die Länge der Gewindebolzen in etwa der Tiefe des Gehäuses und jeder Gewindebolzen weist an seinem Ende eine umlaufende Nut auf, in die ein Haltedraht eingreift und jeweils zwei benachbarte Gewindebolzen über die Gehäuserückseite miteinander verbindet. Damit sind die Gewindebolzen an ihrem Ende stationär drehbar gelagert. Dabei ist die Befestigung mittels eines Haltedrahtes besonders einfach herzustellen. Über den Haltedraht werden zwei benachbarte Gewindebolzen miteinander verbunden, so daß sie nicht von den Seitenwänden der Gehäuse nach außen ausweichen können.As a variant of the invention, the length of the threaded bolts corresponds about the depth of the case and each threaded bolt has a circumferential groove at its end, into which a holding wire engages and two adjacent threaded bolts each connects the back of the case. So that are the threaded bolts rotatably supported at its end. It is attachment with a holding wire is particularly simple to manufacture. Two adjacent threaded bolts are placed over the retaining wire interconnected so that they are not from the Side walls of the housing can escape to the outside.

Denkbarerweise kann der Haltedraht an der Gehäuserückseite an eienm in Verlängerung einer Seitenwand ausgebildeten Steg anliegen. Dadurch ist der Haltedraht gegen Herunterrutschen von der Gehäuserückseite gesichert. Auf die Gewindebolzen einwirkende Kräfte können über den Haltedraht an dme Steg abgestützt werden.Conceivably, the retaining wire can be attached to the back of the case Fit a web formed in the extension of a side wall. This prevents the retaining wire from slipping off the back of the case. Acting on the threaded bolts Forces can be supported on the web via the retaining wire become.

Möglicherweise können die Gewindebolzen und die Gewinde der Verankerungselemente mehrgängig ausgebildet sein. Dadurch kann über Gewindebolzen und Gewinde bei wenig Drehbewegungen ein großer Weg übertragen werden, ohne die Gewinde zu beschädigen.Possibly the threaded bolts and the threads of the Anchoring elements should be designed with multiple threads. This can via threaded bolts and thread with little turning movements great way to be transmitted without damaging the threads.

Besonders vorteilhaft kann die Bewegungsbahn und/oder die abgeflachte Gehäusekante stärker geneigt sein als die benachbarten Seitenwände. Damit verjüngt sich der Umriß der Bewegungsbahn bzw. der Gehäusekanten von der Frontseite des Gehäuses zur Rückseite hin gesehen stärker als die benachbarten Seitenwände, so daß ein größerer seitlicher Schiebeweg der Verankerungselemente möglich ist.The path of movement and / or the flattened can be particularly advantageous Edge of the housing must be more inclined than the neighboring ones Side walls. This narrows the outline of the trajectory or the housing edges from the front of the housing to The rear is stronger than the neighboring side walls, so that a larger lateral sliding path of the anchoring elements is possible.

Besonders vorteilhaft ist in einen Absatz der Gehäuseöffnung eine transparente Scheibe mit Gummiumrandung eingesetzt. Dadurch ist die transparente Scheibe von der Frontseite her an der Leuchte auswechselbar befestigt. Die Gummiumrandung stützt die Scheibe federnd an dem Absatz ab und dichtet den Raum zwischen Scheibe und Absatz ab.Is particularly advantageous in a paragraph of the housing opening a transparent pane with a rubber border is used. Thereby is the transparent pane from the front the lamp is interchangeably attached. The rubber border supports the disc resiliently from the heel and seals the space between Disc and heel off.

Günstigerweise kann an der Frontseite eine über den Rand reichende Abdeckung an dem Gehäuse befestigt sein. Durch die Abdeckung werden das Gehäuse und etwaige von der Frontseite sichtbare Befestigungsmittels abgedeckt. Durch entsprechende Wahl der Abdeckung kann die Leuchte dem Aussehen und Zweck am jeweiligen Einbauort angepaßt werden.Conveniently, one can reach over the edge at the front Cover to be attached to the housing. Through the cover be the case and any from the front visible fasteners covered. By appropriate Choosing the cover can change the look and purpose of the lamp the respective installation location.

Besonders vorteilhaft übergreift die Abdeckung die transparente Scheibe mit einem Vorsprungsrad. Dadurch ist die transparente Scheibe in dem Absatz sicher befestigt und kann nach Abnehmen der Abdeckung ausgewechselt werden.The cover particularly advantageously overlaps the transparent one Disc with a projection wheel. This makes the transparent Washer securely fastened in the heel and can be removed after removal the cover.

Als bevorzugte Ausführungsform weist die Abdeckung im Bereich der Gehäuseöffnung mehrere parallel im Abstand zueinander angeordnete, schräg angestellte Lamellen auf, die zwischen sich Durchtrittsschlitze begrenzen. Dadurch wird das durch die Gehäuseöffnung tretende Licht von den Lamellen abgelenkt und gerichtet. Diese Leuchte kann beispielsweise als Fußraumleuchte oder Orientierungsleuchte verwendet werden.As a preferred embodiment, the cover has in the area the housing opening a plurality of parallel spaced slanted slats on, between themselves Limit through slots. This will through the opening in the housing stepping light deflected and directed by the slats. This lamp can be used, for example, as a footwell lamp or orientation light can be used.

Möglicherweise kann die Abdeckung im Bereich der Gehäuseöffnung eine transparente Scheibe aufweisen.The cover may be in the area of the housing opening have a transparent disc.

Denkbarerweise kann die Abdeckung an dem Gehäuse festgeschraubt sein.Conceivably, the cover can be screwed onto the housing be.
