Definitions

  • the invention relates to a luminaire housing with at least one hook-shaped spring for releasably holding inserts, such as tubs or grids.
  • Leaf springs have so far been riveted or screwed onto the luminaire housing.
  • a specially curved wire spring is also known, which can be inserted into corresponding recesses in the lamp housing and then holds itself positively and positively.
  • the invention has for its object to further simplify the manufacture of such springs and their assembly on a lamp housing.
  • the solution to this problem is characterized in the invention by the features specified in claim 1.
  • the spring used in the invention has a much simpler shape and is therefore cheaper to manufacture; on the other hand, the costs for the additionally required coupling part, which is preferably made of plastic, are negligible, especially since this reduces assembly to a simple plugging or pushing together.
  • the locking lug is preferably arranged at a distance from the hammer head, on the side that it is pressed behind the locking edge when the spring is tensioned, that is to say when the cover is inserted, and is thus secured in this position.
  • the locking edge can be part of a separate recess in the wall of the lamp housing; however, this is preferably used .
  • the invention is applicable to wire and leaf springs; the latter, however, must have two free legs that receive the neck of the hammer head between them.
  • each free leg of a spring ends in an angle piece, which is in a corresponding recess in the coupling part and thus secures the spring therein; these elbows can run perpendicular or parallel to the wall of the lamp housing.
  • the angle pieces run perpendicular to the wall of the lamp housing and enclose with it an angle which deviates somewhat from the angle which the associated cutouts in the coupling part form with the wall of the housing; the direction of this deviation is chosen so that the spring presses the locking lug of the coupling part behind the locking edge of the housing.
  • a spring 4 is attached to the wall of a lamp housing designated by 1 with the aid of a coupling part 3 and engages behind the edge 51 of a lamp trough 5 with its hook-shaped end 41.
  • the U-shaped spring has two free legs 42 (FIG. 4), each of which has an angle piece 43 at its end (FIG. 1).
  • the coupling part molded from plastic, consists of. essentially from a plate 30, which have recesses 33 and 34 on the side facing the wall 1 of the housing for receiving the free legs 42 or the angle pieces 43. Furthermore, a T-shaped hammer head 31 projects from the same side of the coupling part, the neck 32 connecting it to the plate 30 being one. has such a length that the wall 1 fits precisely between this plate 30 and the hammer head (FIG. 3). Furthermore, the coupling part 3 has on this side a locking lug 35, which is arranged at a distance above the hammer head 31.
  • the latter has a T-shaped recess 2 with a push-through part 21 and a holding part 22 (FIG. 2).
  • the push-through part is dimensioned so large that the hammer head 31 fits through; the holding part 22 is correspondingly smaller so that the neck 32 of the hammer head can be pushed in in the direction of the arrow shown in FIG.
  • the dimensions of the recess 2 are based on that of the hammer head and on the distance of the detent 35 from the hammer head 31 so that the detent 35 behind the upper edge te 23 of the recess 2 engages when the hammer head is inserted to the lower edge of the holding part 22 (FIG 1).
