Definitions

  • the invention relates to a ventilation grille with a housing formed by side walls, which encloses an opening into which the slats are inserted, and has a rear wall with slots which is occupied by a slider.
  • Ventilators are known in various forms and designs and described in DE-OS 39 07 559. They are used to guide the supply and exhaust air in air conditioning systems and have horizontal or vertical, teardrop-shaped slats on the front. They can be made of metal or plastic and serve a variety of applications.
  • Ventilation grille the slider is already mounted in the housing.
  • the sheets adhere to one another through the powder or the paint and can re-form the painting process can no longer be operated easily.
  • the present invention has for its object to improve the displacement of the slit slide after assembly and the painting process in both a technical and functional point of view.
  • the rear wall and / or at least one side wall of the housing is / are provided with at least one projection.
  • the projections are preferably formed in one operation together with the manufacture of the housing.
  • the housing is preferably formed in one piece, whereby welding work is avoided, which benefits the environment.
  • Figure 1 is a front view of a ventilation grille according to the invention
  • Figure 2 is a partially illustrated longitudinal section through the ventilation grille according to Figure 1 along the line II-II;
  • FIG. 3 shows a cross section through the ventilation grille according to Figure 1 along the line III-III;
  • FIG. 4 shows an enlarged section of the section encircled in FIG. 3 and numbered X.
  • a ventilation grille R consists of a housing 1 which forms an opening 2 at the front.
  • This housing 1 is made from a strip of material. It has a rear wall 3 which is clearly recognizable in FIG. 2 and in which slots 4 are stamped.
  • An edge stiffener 7 or 8 protrudes from each side wall 5, which overlap in the corner points and is connected to one another there by rivets 9. These rivets 9 in the rivet points also serve to fasten the ventilation grille R, for example on a sheet metal duct of an air conditioning system or the like.
  • a slot slider 10 is placed on the rear wall 3 through the opening 2, through which also
  • Punched-out slots 11 are formed, which essentially correspond to the slots 4 of the rear wall 3 to match.
  • the slots 11 are punched along three circumferential sides of the slot 11, so that a punched-out wing 12 can be bent. This avoids, among other things, eddy formation within the housing 1 or the actual housing box.
  • Guide strips 13 and 14 are also bent upward and downward from the slit slide 10. These guide strips 13 and 14 are partially overlapped by clamp strips 15 which pass through an upper and lower side wall 16 and 16a, as shown in FIGS. 2 and 3.
  • the clip strips 15 are arranged in such a way that a displacement of the slit slide 10 along the rear wall 3 is released, so that the slits 4 can be opened or closed in whole or in part.
  • Horizontal slats 17 are inserted in the opening 2 of the housing 1 and can be rotated about an axis 18.
  • vertical slats can also be used instead of horizontal slats
  • Each lamella 17 is preferably movable about its axis 18.
  • the rear wall 3 and the side wall 16 are provided with projections 19, 20 which form points of contact 21 with the slot slide.
  • a gap a is thus formed between the slit slide 10 and the rear wall 3 or the side wall 16 by the projections 19, 20.
  • These projections 19, 20 are preferably arranged in such a way that, on the one hand, as a spacer, they make it easier to slide the slider 10 back and forth and, on the other hand, make a smooth painting process possible.
