Definitions

  • the invention relates to a system with a functional unit for a building opening shading device and with a fastening arrangement that can be pre-assembled on the building side, suitable for fastening the functional unit in the fastening arrangement that can be pre-assembled on the building side, according to the preamble of claim 1.
  • U-shaped fastening brackets are provided to form the fastening arrangement. These brackets are provided on their underside with a pivoting locking bracket that can be moved from an open position to a closed position. When open, this locking bracket allows the functional unit, which in this case is provided with a box-shaped housing, to be pushed in, and when closed, engages underneath it, so that it is secured against slipping out as desired. While the locking brackets are being actuated, however, the pushed-in functional unit must simultaneously be manually held in position and secured against falling. This, however, proves to be very difficult and strenuous. The known arrangement therefore proves not to be sufficiently easy to install.
  • the international patent application WO 2019/148219 A1 shows an arrangement for fastening the box-shaped, bottom-open top rail of a Venetian blind to a building surface, wherein a fastening bracket is provided, the side legs of which can be expanded against their inherent elasticity and which each have a projection provided with an indentation at their lower ends.

  • the box-shaped top rail is first inserted into the indentation with the lower end of a side leg in a position inclined relative to the fastening bracket.
  • the German patent application DE 10 2004 016 545 A1 shows an arrangement for the quick installation of the box-shaped, upwardly open top rail of a Venetian blind to an associated housing ceiling with a ceiling-mounted mounting bracket, one leg of which is provided with a retaining claw at its end and the other leg of which is designed as a spring leg provided with a retaining claw.
  • the upper ends of the box-shaped top rail, which is open at the top, are provided with hooking claws.
  • a holding claw of the top rail is hooked into the associated hooking claw on the bracket side.
  • the box-shaped top rail is swung upwards with the other side and, in doing so, its hooking claw there engages the associated holding claw of the spring leg.
  • the DE 10 2004 016 545 A1 removable fastening device therefore only contains a single-stage fastening of the box-shaped top rail in The shape of the locking mechanism for the upper ends of the side legs of the top rail in the side legs of the mounting bracket. This known arrangement therefore also proves to be insufficiently secure and reliable.
  • the upwardly closed box of a Venetian blind is provided with locking strips projecting outwards in the area of its upper corners.
  • the associated retaining bracket is provided with inner retaining claws assigned to the locking strips, one retaining claw being fixed and the other spring-loaded.
  • the box is first tilted relative to the mounting bracket with one edge strip inserted into the fixed retaining claw and then rotated into the mounting bracket until the other edge strip engages in the spring-loaded retaining claw.
  • German patent application DE 1 921 979 A1 discloses a generic system.
  • This system is an arrangement for attaching the box of a roller blind to a ceiling or wall with a bracket-shaped holding part that overlaps the said box and can be attached to the ceiling, etc., and has two undercut recesses in the upper corners into which the box, which is open at the top, can be snapped into place by means of corresponding bends in the upper ends of its lateral legs, whereby the box is temporarily held in the snapped-in position.
  • An arm is provided that engages beneath the box, which can be snapped onto the lower end of the lateral legs of the bracket-shaped holding part. This arm is provided with locking notches into which suitable locking projections on the lateral legs of the holding part can snap.
