Definitions

  • the invention relates to a rectangular lamp frame according to the preamble of claim 1.
  • Such a lamp frame known from DE-A-1589253 consists of two identical longitudinal and two identical transverse walls with the same cross-section; these parts are preferably separated from an extruded profile with 45 ° cuts.
  • the invention has for its object to provide a simple connection of the transverse and longitudinal walls of a lamp frame with a small horizontal depth, the corners should be free of joints and joints.
  • each corner connector which protrudes outwards and runs at 45 °, in relation 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 other wall.
  • connection of the longitudinal and transverse walls by plugging them together is so simple that it can be done 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.
  • the plastic corner connector 2 has two mutually perpendicular coupling walls 21, 22 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 ends 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, which has an opening angle ⁇ , ⁇ of less than 90 ° against a reference line G through the openings of the guide grooves 11, 12; 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 - rest 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. Any tolerances are compensated for by the pressure strips 213, 223, which deform on the one hand and the corner connectors on the other when the transverse and longitudinal walls are put together.
