Definitions

  • the cover (grid, trough) of the light exit opening of a lamp is preferably pivotally mounted on a longitudinal edge of the lamp housing, it also being possible to completely unhook it in a certain, uncritical angular range.
  • this simplest bracket requires a sufficient swivel range within the luminaire housing, which is not always the case. In such cases, brackets have been used that work with retaining springs that get caught in a part of the lamp housing when the cover is removed. The springs can then be manually detached from the lamp housing for one-sided pivoting or complete removal of the cover.
  • the invention relates to the holder of such a lowerable lamp cover according to the preamble of claim 1. It is based on the object of improving such a holder so that the cover can be pivoted away on a long side of the lamp after loosening the retaining springs. The achievement of this object is characterized in a holder of the type mentioned in claim 1.
  • the invention is characterized by a particularly simple design of the edge region of the cover. nevertheless, a perfect mounting is guaranteed and accidental unhinging is practically impossible.
  • the suspension spring resiliently bare Cut edges of the cover and the spring holder, so that a perfect electrical connection is always guaranteed between the two, even if these parts consist of coated sheet metal.
  • the spring holder is preferably made of rustproof material, in particular of hot-dip galvanized sheet metal, and mechanically connected to the lamp housing in such a way that a secure electrical connection is thereby ensured at the same time.
  • the spring holder 2 is fastened with side support walls 22 and an upper support wall 24 to the side wall 11 and / or the housing cover 12 of the lamp housing 1, the side support walls 22 having angled plug-in arms 221 at their lower ends that reach through assigned slots 111 in the side wall 11 of the lamp housing.
  • the lateral support walls 22 of the spring holder 2 are offset relative to its top wall 20 by approximately the thickness of the suspension spring 4, so that a guide space 23 is formed between the top wall 20 of the spring holder 2 and the side wall 11 of the lamp housing 1, which is parallel from below through a guide slot 231 is accessible to the side wall 11 and is laterally limited by the side walls 21 of the spring holder 2; the distance b of these side walls (FIG 2) is smaller than that Distance B between the projections 43 of the suspension spring 4.
  • the lamp cover 3 arranged in the light exit opening 13 of the lamp housing 1 is shown here as a grid with a longitudinal wall 30 which has a V-shaped, upwardly open edge region with a longitudinal edge 31 at the bottom.
  • the latter is bent over it in the area of the bearing arms 411 of the suspension spring 4 and thus forms bearing pieces 311 in which the bearing arms 411 can be rotated and have the inlet openings 3110 directed towards one another Support arms 41 of the suspension spring are pressed against each other.
  • This is no longer possible even after a small rotation of the longitudinal wall 30 (in the direction of the arrow in FIG. 1), since the locking tab 313 (see FIG. 2) then enters between the support arms 41 of the suspension spring and thus limits their freedom of movement.
  • the lamp cover 3 is therefore already secured against inadvertent detachment from the suspension spring when it is swiveled down and in particular in the swiveled-out state.
  • a piece of the longitudinal edge 31 forms an earthing tab 312 which is bent inwards so far that the free end face of the bearing arms 411 of the suspension spring resiliently presses against its cutting edge 3121: this creates a ground connection between the suspension spring and Luminaire cover 3 is produced, which is also guaranteed when the longitudinal wall 30 of the luminaire cover 3 consists of pre-coated sheet metal.
  • a projection 43 which is formed by a support leg 432 and a thigh 431 running approximately at right angles thereto, the downward-pointing support leg 432 forming an acute angle ⁇ with the plane of the light exit opening.
  • this angle is so large that this supporting leg 432 rests on the supporting edge 211 at the upper end of the side walls 21 of the guide space 23 with sufficient friction resistance to hold the lamp cover 3 in the light exit opening 13 (FIG. 2, drawn position of the supporting spring 4).
  • the inclination of the support leg 432 enables the cover to be pulled down, the projections 43 of the support spring 4 being pressed against one another until they finally enter the guide space 23 and slide along the side walls 21 of the guide space 23 as they are pulled down, and also for one ensure a safe ground contact (position of the suspension spring 4 'in FIG 2).
  • the range of motion of the suspension spring 4 downwards is limited by hooks 201 which protrude into the guide space 23 and on which the suspension spring 4 hooks (position of the spring denoted by 4 ′′ in FIG. 2).
  • the thighs 431 of the projections 43 then press against the lower edge 212 of the side walls 21 of the spring holder 2 and thus secure a ground connection.
  • the dimensional relationship shown in FIG. 2 is assumed and also / that the support arms 41 of the support spring -4 in the position shown in FIG. 2 press against the earth tab 312 with a preload.
  • FIGS. 4 to 6 An alternative to this is shown in FIGS. 4 to 6, in which a molded bearing part 5, preferably made of plastic, is provided, which both has two spaced-apart bearing pieces 511 and a locking tab 512 located between them.
  • This shaped bearing part 5 is placed on the free leg of the U-shaped longitudinal edge 31.13, which for this purpose has a somewhat recessed edge 31.13 and two recesses 31.11 for receiving the locking hooks 521 of spring legs 52 of the shaped bearing part.
  • Each spring leg 52 runs at a distance corresponding to the thickness of the sheet metal of the cover from a main leg 51 of the shaped bearing part 5.
  • the edge 31.13 of the longitudinal edge 31.1 of the cover 3.1 is set back from the edge of this free leg approximately by the height of the bearing pieces 511, so that the ends of the bearing arms 41'1 resiliently rest on the cutting edges 31.12 of the adjacent earthing tabs 312.1.
  • a spring holder 2.1 made of galvanized sheet metal is provided for each support spring 4.2 and is fastened to the housing cover 12 by means of a support wall 24.1.
  • This spring holder encloses with its top wall 20.1 and laterally angled guide walls 22.1 (FIG. 9) the guide space 23.1, which is laterally delimited by side walls 21.1 and protrude into the hook 201 .1 from the top wall 20.1.
  • each suspension spring 4.2 The two free ends of the support arms 41.2 of each suspension spring 4.2 are angled twice, namely once within a plane parallel to the light exit opening 13 and also in a plane perpendicular to this light exit opening: parallel to the plane of the light exit opening and to the longitudinal edge 31.2 of the cover 3.2 there is a free end piece in each case 410.2;
  • the bearing arm 411.2 (FIG. 11) perpendicular to this end piece 410.2 is also arranged in the same plane. This is also approximately perpendicular to the side wall 11 of the lamp housing 1.
  • the longitudinal edge 31.2 of the cover 3.2 has a slot-shaped recess 31.20 for each supporting spring 4.2, which runs parallel to this longitudinal edge and to the light exit opening (FIG. 10). Through this recess, the support arms 41.2 of each support spring with their bearing arm 411.2 and the adjoining end piece 410.2 engage in the upwardly open V-shaped edge region of the cover (FIG. 11).
  • the cover 3.2 is pivoted into the light exit opening 13 of the lamp housing 1 - as shown in broken lines in FIG. 11 - the upper edge 31.21 of the recess 31.20 rests on the bearing arms 411.2 of each suspension spring 4.2. If, on the other hand, the cover is pivoted out - as shown in FIG. 11 - then it lies on the bearing arms 411.2 with the edge 31.23 of its longitudinal edge 31.2.
  • each support spring 4.2 To unhook the cover, the support arms 41.2 of each support spring 4.2 must be pressed against one another until both end pieces 410.2 can pass through the slot-shaped recess 31.20. With the appropriate length of these end pieces, a random, unintended. Visible hanging of the cover excluded.
  • the length of the recess 31.20 is slightly smaller than that Width b of the guide space 23.1 of the spring holder 2.1 (FIG. 8): This ensures that the ends of the support arms 41.2 always bear against the lateral cutting edges 31.22 of this cutout 31.20 and provide an electrical connection.
