Connection device for multipart luminaires, in particular luminaires having at least one fluorescent lamp

摘要

Multipart luminaires (10), in particular with a fluorescent lamp (11), have a rail (12) which can be fastened, for example, to a room ceiling and an implement carrier (tool carrier, accessory rack) (13) which can be fixed to the rail (12). The connection of these two parts, which consist of sheet steel, is carried out by rotating brackets (14) which in turn are arranged such that they can be rotated on the implement carrier (13) by means of plastic parts, to be specific a handle piece (20) and a fastening part (26). These plastic parts are subject to aging, with the result that there is the risk of a fracture (breakage) after a certain time and the connection between the plastic parts is released, so that the implement carrier (13) of the luminaire (10) may fall down. A crash protection is provided in order to avoid this. This crash protection has securing tongues (17) on the rotating brackets (14). The implement carrier (13) is provided with longitudinal edges (29) which are angled off towards the outside and which engage over the securing tongues (17) when the rotating brackets (14) are in their active position in which they connect the implement carrier (13) to the rail (12). When the connection between the plastic parts is released, the implement carrier (13) gets stuck on the securing tongues (17) of the rotating brackets (14) which in turn are in engagement with the rail (12).
