Description

The invention relates to a suspension on a ceiling rectangular, transverse and longitudinal sides exhibiting, sound-absorbing ceiling canopy.

Ceiling canopies are large plate-shaped elements that are hung on the raw ceiling of a room individually or in a composite for decorative and / or sound-absorbing purposes.

The object underlying the invention is to provide a simple to assemble from components, acting as a monolithic part ceiling sail with low weight, high sound absorption and despite large dimensions very small sag.

This object is achieved by a ceiling sail, which has a room-side viewing element, a cover-side closure element and in between transverse, parallel connecting profiles.

The room-side viewing element has the shape of a first lower perforated plate made of thin metal sheet with acoustic fleece overlay and a closed, upstanding to the ceiling edge. The edge has two longitudinal side skirting and two obliquely inwardly over the first plate inclined, transverse side edge portions which merge at turn ends in a right angle to the first plate to bent edge flange whose free end edge faces the first plate.

The cover-side closure member has a second upper perforated plate of thin metal sheet with acoustic fleece insert and with through holes for suspension elements and a closed, projecting from her edge having two longitudinal side edges and two transverse edge portions, which together in the associated edge strips and edge portions of the first plate Contact are so fit that the second plate is flush with the bent ends of the transverse edge portions of the first plate.

The at least two parallel to the transverse edge portions of the viewing element connecting profiles are substantially U-shaped. Each of the connection profiles has a long magnetic adhesion leg for a magnetic adhesion to the first plate, a web which has substantially the height of the transverse edge portion of the viewing element, and a short leg with locking slots, which to the through holes of the closure element for the insertion and holding the Suspension elements are aligned.

Fixing devices are provided for holding the closure element in the viewing element.

As fixing means elastically bent Schnapplaschen are provided with the second plate facing Halteränder at the transverse edge portions of which have the same distance from the same as the free end edges of the edge flange of the transverse edge portions of the viewing element. When the closure element is inserted into the viewing element, the retaining edges of the elastically depressible snap-in lugs of the closure element engage behind the end edges of the edge flanges of the viewing element, whereby the latter is held by the closure element.

In order to minimize the sag of the ceiling sail three connecting profiles are arranged parallel to the transverse side edge portions on the first plate.

The adhesive leg of the connection profile is advantageously magnetized by applying a magnetic strip.

Preferably, the helix angle between the transverse edge portions and the first plate of the viewing element is 47 °.

Conveniently, the thickness of the metal sheet used is 0.6 mm to 1 mm.

The extra microperforated first panel of the visual element has a sag of less than 3 mm, which is achieved by means of the longitudinally evenly distributed, transverse connection profiles is reached. The holding force between the connection profiles and the visual element, on which the acoustic fleece padding is located on the inside, takes place with the aid of the magnetic strips. For the suspension of the ceiling sail four steel cables are provided, of which each attack two adjacent to the respective transverse side connecting profile. The standard perforated, internally provided with acoustic fleece insert closure element is specially prepared and is exactly aligned without tools in the viewing element from the back side latched.

According to one embodiment, the longitudinal edge strips of the viewing element have a shorter extension from the first plate than the transverse edge strips and are bent at their ends to the first plate parallel and extending over them end flanges. The longitudinal edge strips are each connected to a rigid edge piece whose height corresponds to the transverse edge portions of the viewing element.

The ceiling sail thus has a generally closed edge with two transverse edge portions which extend obliquely inwardly over the first plate, and two longitudinal edge strips with rigid edge pieces, wherein the raw ceiling side facing surface of the ceiling sail the second plate of the closure member and the room side facing surface of the ceiling sail is the first plate of the visual element.

In this embodiment, the connection profiles are frontally notched so that they rest with a flange on the longitudinal side edge of the viewing element and can be riveted with it and the associated rigid edge piece.

Conveniently, as a further fixing means attached to the rigid edge pieces mounted spring steel clips, which are engageable with the longitudinal edge strips of the closure element for its positional fixation on the viewing element in plug-in engagement.

The ceiling sail in this embodiment may be modified to have a convex or concave curvature in its longitudinal direction. This is achieved in that the rigid edge pieces are curved concave or convex and in their connection the concave or convex curvature is impressed on the longitudinal edge strips of the viewing element by the ceiling sails correspondingly bending in its longitudinal direction.

If the ceiling sail is to have a concave or convex curved shape, its viewing element is placed on a correspondingly curved pad and the corresponding curved edge pieces inserted or otherwise fixed to the transverse edge portion. Thereafter, the connecting profiles are attached with their magnetic strip on the first plate of the visual element adhesive in parallel execution and predetermined intervals, so that their end flanges abut the longitudinal edge strips of the visual element. Their connection with each other and with the associated rigid edge piece is advantageously carried out by riveting. Thereafter, the closure member is introduced, which deforms itself bending in accordance with, until the second plate is flush with the transverse side edge portions and the longitudinal side edge pieces. The connection is made by the spring steel clips that sit on the rigid edge pieces.

In a further embodiment of the ceiling sail, the longitudinal edge strips of the viewing element as its transverse edge portions are inclined inclined inwardly over the first plate, have the same height as the transverse edge portions and go at turn ends in right angles to the first plate to bent edge flanges over whose free end edges of the first plate are facing and lie in the same plane as the end edges of the edge flanges of the transverse edge portions.

The edge of the closure element may longitudinally have a longitudinal flange parallel to the second plate, which contributes to the stiffening and can also serve as a support contact on the first plate.

For better anchoring of the connection profiles, these can each end adapted for Hintergreifung the skew of the longitudinal edge portions of the viewing element adapted notches.

For the assembly of such a ceiling sail the finished visual element is placed on a flat surface. Then, parallel to the transverse edge portions at equal intervals, the connecting profiles with their magnetic strips on intended markings placed so that the ends of the longitudinal edge strips attack and can be attached. Subsequently, the closure element is inserted with its edge ahead in the visual element in a tight fit and fixed by the engagement of retaining edge and snap tab in a simple manner.

The attached to the long leg 31 of the connection profiles 30 magnetic tapes 35 provide through the non-woven pad for a firm adhesion of the connection profiles 30 to the first plate 12th

When the connecting profiles 30 are arranged in the visible element 11 as described above, the closure element 22 is pushed with its edge 24 along the edge flange 14 of the viewing element 11 from above, until the second plate 22 with its fleece insert having inner surface on the short legs 33 of Connection profiles 30 rests. In this position, the free end of the rim 24 or its inflected end flange 27 can stand up on the inner surface of the first plate 12 of the viewing element 11 provided with the nonwoven support. At the same time the Schnapplaschen 25, which are pressed upon insertion of the edge 24 of the closure member 21 along the edge flange 14 of the viewing element 11, passes under the end edge 15 of the edge flange 14 and therefore can snap out so that they with their Halteränder 26, the closure element 21 on the Secure the sighting element 11 across against being pulled out. On the longitudinal side, the longitudinal flange 27 with its punched-out portions 243 snaps into the hook formations 361 in the connection profiles 30. In this mounting position, the outer surface of the second plate 22 of the closure element 21 is aligned with the portion of the edge 13 of the viewing element 11 which is parallel to the first plate 12.

At the same time in this mounting position, the through holes 23 are aligned with the locking slots 34 in the short legs 33 of the connection profiles 30, so that suspension elements 40 (FIG. Fig. 9 ) can be anchored in the locking slots 34 for the suspension of the ceiling sail.

In Fig. 9 For simplicity, only one connection profile 30 is shown. Another connection profile is central, the third used symmetrically to the first.

In the Fig. 11 to 20 shown second embodiment of the ceiling sail consists essentially of the same elements as the ceiling sail of the first embodiment.

How out Fig. 11 to 13 can be seen, the visible surface 11 of the second embodiment has opposite, transverse edge portions 132 which extend at an angle of 47 ° obliquely inwardly over the first plate 12 and in a direction perpendicular to the plate 12 facing bent edge flange 14 ends. The viewing element also has longitudinal edge strips 131, which are bent perpendicular to the first plate 12 and form a closed edge 13 with the transverse edge portions 132. The height of the longitudinal Edge strips 131 is substantially smaller than that of the transverse edge portions 132. As out Fig. 13 As can be seen, the longitudinal edge strips 131 are bent perpendicularly inwardly beyond the first plate 12 to a longitudinal end flange 141 which is parallel to the first plate 12. Furthermore, markings 151 are provided for the assembly of the connection profiles 30.

The shutter member 21 of the second embodiment of the ceiling sail has a second plate 22 which, like the first plate 12, is provided with a nonwoven acoustic pad as in the first embodiment. The second plate 22 has opposite transverse edge portions 242 with snap tabs 25 and opposite longitudinal side edges 241, which together form an edge 24 whose height extent is greater at the transverse edge portions 242 than at the longitudinal side edges 241. The longitudinal side edges 241 are perpendicular at their ends bent, which are formed to the second plate 22 parallel longitudinal flanges. On the second plate 22, as in the first embodiment, evenly distributed four through holes 23 are provided.
