Description
Die Erfindung betrifft eine Anbauleuchte mit deckenseitigen und leuchtenseitigen Befestigungselementen, die miteinander verbindbar sind, wobei die deckenseitigen Befestigungselemente durch ein Winkelelement mit einem Basisschenkel und sich quer erstreckenden Halteschenkeln gebildet sind.The invention relates to a surface-mounted luminaire with cover-side and luminaire-side fastening elements, which are connectable to one another, wherein the cover-side fastening elements are formed by an angle element with a base leg and transversely extending retaining legs.
Eine derartige Anbauleuchte ist beispielsweise in der
Es hat sich herausgestellt, dass die Montage der deckenseitigen Befestigungselemente insbesondere bei Verwendung von Akkuschraubern schwierig ist, weil das deckenseitige Befestigungselement beim abschließenden Festziehen der Schraube nicht immer in der gewünschten Position verbleibt, sondern sich mit der Schraube mitdrehen kann.It has been found that the mounting of the ceiling-side fasteners is difficult, especially when using cordless screwdrivers, because the cover-side fastener does not always remain in the desired position during final tightening of the screw, but can rotate with the screw.
Aufgabe der Erfindung ist es die Anbauleuchte der eingangs genannten Art so zu verbessern, dass das deckenseitige Befestigungselement bei der Montage nicht mehr unbeabsichtigt verdreht wird.The object of the invention is to improve the surface-mounted luminaire of the type mentioned so that the ceiling-side fastener is not accidentally rotated during assembly.
Die Aufgabe wird gelöst durch die kennzeichnenden Merkmale des Anspruchs 1. Hierbei ist erfindungsgemäß vorgesehen, dass einem Basisschenkel des deckenseitigen Befestigungselements, an der der Leuchte abgewandten Seite aus der Ebene des Basisschenkels austretende Elemente angeformt sind, die geeignet sind, sich im montierten Zustand des deckenseitigen Befestigungselements mittels eines Montagelements, wie beispielsweise Schrauben, in eine Decke zu verkrallen. Hierzu sind die aus der Ebene des Basisschenkels austretenden Elemente durch frei gestanzte Zungen gebildet. Diese liegen in Übergangsbereichen von Basisschenkel und Halteschenkeln. Nachdem beim Festschrauben des deckenseitigen Befestigungselements dieses zwischen Schraubenkopf und ggf. einer Beilagscheibe und Decke eingeklemmt wird, wird das deckenseitige Befestigungselement gegen die Decke gedrückt. Dies hat zur Folge, dass sich die aus der Ebene des Basisschenkels austretende Elemente in die Decke verkrallen können und einer Verdrehung während des Festziehens der Schraube
entgegen wirken.The object is achieved by the characterizing features of claim 1. Here, the invention provides that a base leg of the ceiling-side fastener, on the side facing away from the lamp from the plane of the base leg emerging elements are formed, which are suitable in the assembled state of the ceiling side Fastening element by means of a mounting element, such as screws, to dig into a ceiling. For this purpose, the emerging from the plane of the base leg elements are formed by freely punched tongues. These lie in transition areas of the base legs and holding legs. After clamping the cover-side fastening element is clamped this between the screw head and possibly a washer and ceiling, the ceiling-side fastener is pressed against the ceiling. This has the consequence that the emerging from the plane of the base leg elements can dig into the ceiling and a twist during the tightening of the screw
counteract.
Die Anbauleuchte weist in der Regel ein Leuchtengehäuse auf, welches Leuchtmittel, Betriebsgeräte und lichtlenkende Elemente aufnimmt. Außerdem können an oder im Gehäuse die leuchtenseitigen Befestigungselemente angeordnet sein. Alternativ dazu kann das Gehäuse selbst oder das Gehäuse bildende Teile, insbesondere Stirn- oder Profilteile, so ausgebildet werden, dass die leuchtenseitigen Befestigungselemente integriert sind. In der Regel sind für eine Anbauleuchte zwei leuchtenseitige und damit auch zwei deckenseitige Befestigungselemente vorzusehen. Hierbei ist das erste leuchtenseitige Befestigungselement in einem sich in Längsrichtung der Leuchte erstreckenden Abstand zum zweiten leuchtenseitiges Befestigungselement angeordnet.The surface-mounted luminaire usually has a luminaire housing which accommodates lamps, operating devices and light-directing elements. In addition, the light-side fastening elements can be arranged on or in the housing. Alternatively, the housing itself or the housing forming parts, in particular end or profile parts, are formed so that the light-side fastening elements are integrated. As a rule, two luminaire-side and thus also two cover-side fastening elements are to be provided for a surface-mounted luminaire. Here is the first light side Attachment arranged in a longitudinal direction of the lamp extending distance to the second light-side fastener.
Vorzugsweise wird ein deckenseitiges Befestigungselement and die Decke geschraubt. Zur Aufnahme von Montagelementen, insbesondere Schrauben, ist eine bevorzugt als Langloch ausgebildete Ausnehmung im Befestigungselement vorgesehen.Preferably, a ceiling-side fastener is screwed to the ceiling. For receiving mounting elements, in particular screws, a preferably formed as a slot recess is provided in the fastener.
In einer bevorzugten Ausführungsform der Erfindung ist das deckenseitige Befestigungselement als ein U-förmiges Winkelelement mit mindestens zwei Halteschenkeln gestaltet. Um eine erste Montageposition der Anbauleuchte zu realisieren, sind die die freien Enden der Halteschenkel hakenförmig ausgebildet. Alternativ dazu können im Bereich der freien Enden Freistanzungen vorgesehen sind, die hakenförmig ausgebildet sein.In a preferred embodiment of the invention, the ceiling-side fastening element is designed as a U-shaped angle element with at least two retaining legs. In order to realize a first mounting position of the surface-mounted luminaire, the free ends of the retaining legs are hook-shaped. Alternatively, free punches may be provided in the region of the free ends, which may be hook-shaped.
