DESCRIPTION:
BRIEF SUMMARY
The invention relates to a fastening arrangement for louver slats arranged below one another on a facade supporting structure, with supporting profiles extending perpendicularly relative to the longitudinal direction of the slats, designed as a rail and having a groove which extends in the longitudinal direction of the profiles and into which are pushed brackets which hold the slats in at least two places and each have a leg resting against the supporting profile and a leg projecting at an angle from the supporting profile, and which are retained in recesses in the supporting profiles by means of extensions on the leg resting against the supporting profile.
An embodiment of this type can be taken from German Offenlegungsschrift No. 2,910,877. This prior publication discloses various embodiments of ventilation gratings. The supporting profiles can be aluminum profiles which have a relatively shallow groove having a rectangular cross-section and extending in the longitudinal direction of the profiles. Brackets are pushed into this groove and, in the assembled state, can rest flush against one another. At the same time, a bracket can, by means of a sloping supporting face provided at its bottom end, be supported on a corresponding supporting face provided at the top end of the bracket located beneath it. That leg of each bracket which carries the extensions rests against the bottom of the said profile groove and carries mushroom-like pegs which are pressed into pre-drilled holes in the bottom of the said profile groove. In the assembled state, the mushroom-like pegs engage behind the said bore in the groove bottom. The bracket leg resting against the latter has, at its top end, a receiving chamber for a web of the slat. The free end of the projecting leg is equipped with a hook which is directed away from the said receiving chamber and which engages into a pocket provided on the underside of the slat. The slat continues downwards via the said projecting leg. The slats each have a groove at both their top end and their bottom end, and the orifices of the lower groove of the particular slat located above and of the upper groove of the particular slat located below are approximately at the same height and face one another. Edge portions of a grating can be inserted into the open grooves arranged at the same height.
In order to fasten a slat, at least two brackets arranged at a horizontal distance from one another are conventionally provided. At least two vertical supporting profiles consequently have to be assembled. Since these supporting profiles already have pre-drilled holes in the known embodiment, highly accurate alignment is necessary during assembly, to guarantee that the individual slats are aligned absolutely horizontally. At the same time, the distance between the uppermost slat and the surrounding masonry and the distance between the bottommost slat and the surrounding masonry have to be determined exactly even before the perforated supporting profiles are assembled. Another disadvantage of the above-described known construction is that the supporting profiles require additional machining by drilling, punching, milling or the like, in order to make the holes for the peg-like extensions of the brackets.
In contrast to this, the object on which the invention is based is to provide a fastening arrangement of the type described in the introduction, which makes much simpler assembly possible.
According to the invention, this object is achieved because the profile recesses of the extensions are formed by the said groove, in which the extensions are held so as to be displaceable, and because the extensions have, at the bottom end of the bracket, a receiving space, into which a filler piece of the bracket arranged below it can be inserted with a clamping effect.
In the fastening arrangement according to the invention, the brackets are inserted into the supporting profiles designed as rails and are displaceable along the supporting profile. Because the filler piece is pushed into the receiving space of the pa
