Definitions

  • the invention relates to a rectangular lamp frame, each consisting of two transverse and longitudinal walls, as is known for example from DE-OS 27 43 257.
  • a luminaire frame With the help of such a luminaire frame, a luminaire which is free-radiating per se can be shielded, wherein grids, prismatic panes or other light-directing elements can be inserted into the lower light outlet opening of the luminaire frame; Therefore, a wide range of luminaires with different lighting properties can be covered with the aforementioned light-directing inserts, a luminaire frame and a free-radiating luminaire.
  • the lamp frame consists of two longitudinal walls made of sheet metal with a C-shaped profile and two transverse walls made of plastic.
  • the required angular stiffness is ensured by transverse legs of the longitudinal walls, which are directed against each other and rest against stop legs of the end walls.
  • the invention is therefore based on the object of creating an easy-to-manufacture, angularly rigid luminaire frame in which the longitudinal and transverse walls consist of the same material.
  • corner connectors preferably plastic injection-molded parts - and an extruded profile are required, from which the transverse and longitudinal walls with the desired dimensions are separated with 45 ° cuts.
  • the connection of these parts by plugging them together is so simple that it can be carried out by the end user; this applies at least to the embodiment in which the connecting tabs of the walls snap into corresponding recesses in the corner connectors and thus secure the parts against pulling apart.
  • corner connectors without recesses and press the connecting tabs of the walls with appropriate pressure into the material of the corner connector: In this case, gaps at the corners can be avoided due to unfavorable tolerances.
  • each corner connector which protrudes outwards and runs at 45 ° with respect to the two coupling walls: this stop rib, which lies between adjacent longitudinal and transverse walls, clearly defines their end positions. Without such a stop rib, on the other hand, the position of one wall would be changed when the other was pushed in as a result of the separating surfaces sliding on one another at 45 °. In the worst case, the corner edge of one wall could protrude beyond the edge of the other wall by an amount corresponding to the wall thickness of the wall.
  • the plastic corner connector 2 has two coupling walls 21, 22 running at right angles to each other with upper edge strips 211, 221 and lower edge strips 212, 222.
  • a stop rib 20 In the corner area, where the two coupling walls 21, 22 meet, runs at 45 ° - in relation to each of the two coupling walls - a stop rib 20, the outer edge of which has the same course as the outer surfaces of the longitudinal and transverse walls to be connected, with which it is flush.
  • recesses 210, 220 are arranged on the outside of each coupling wall and pressure strips 213, 223 are arranged on the inside in the lower edge region.
  • Longitudinal wall 1 and transverse wall 1 ' are sections of an identical profile with an essentially C-shaped cross section and inwardly folded edge strips 14, 15 which each form a guide groove 11, 12 with the inside of the transverse or longitudinal wall, the opening angle ⁇ a, ⁇ comprises less than 90 0 to a through the openings of the guide grooves 11, 12 defined reference line G; these opening angles are preferably chosen to be as small as possible.
  • the shape of the coupling walls 21, 22 of the corner connector corresponds exactly to the profile of the longitudinal and transverse walls, so that these longitudinal and transverse walls - As shown in Fig. 4 - lie snugly on the outer surface of the coupling walls 21, 22.
  • the edge strips 14, 15 of the coupling walls are inserted in the guide grooves 11 and 12. Possible tolerances are compensated for by the pressure strips 213, 223, which deform on the one hand and the corner connector when transverse and longitudinal walls are put together.
