DETAILED DESCRIPTION OF THE INVENTION

[0066] FIG. 1 shows an acoustic ceiling island platform 1 attached to a structural ceiling 2 by a suspension cable set 3. The acoustic ceiling island platform 1 comprises an outer frame profile 4 forming an outer, surrounding frame of the acoustic ceiling island platform 1. Within the outer frame profile 4, carrier profiles 5 extend in a parallel manner to each other between opposite sides of the outer frame profile. In relation to the invention the term carrier profile also covers the outer frame profile 4 which is just to be considered a specialised shaped carrier profile of the system. Perpendicular carrier profiles 5a extend in a parallel manner to each other and perpendicular to the carrier profiles 5 and in the same level as the carrier profiles 5, wherein the perpendicular carrier profiles 5a stabilize the carrier profiles 5 by connecting the carrier profiles with a part of the outer frame profile 4 not otherwise connected to the carrier profiles 5 as shown in FIG. 1.

[0067] Perpendicular to the carrier profiles 5, main runners 6 extend in a parallel manner to each other below the carrier profiles between opposite sides of the outer frame profile. Ceiling tiles 7 are carried by the main runners 6 for creating a smooth and sound-absorbing surface on the underside of the acoustic ceiling island platform 1.

[0068] FIG. 2 shows a cross-section of the outer frame profile 4 with a smooth outer face 8 and an inner face 9 comprising a first recess 10. An attachment clip 12 is connected to the outer frame profile 4 by a nut 14 and a bolt 16, with a bolt head 18 inside the first recess and retained by the first recess. A wing 20 of the attachment clip 12 is protruding into the first recess. The wing 20 has two first chamfers 22 for making introduction of the wings into the first recess 10 easier.

[0069] A part of one of the main runners 6 is also shown, where the main runner is held by the attachment clip 12.

[0070] The outer frame profile 4 is in the shown embodiment provided with recesses 13 at the top and bottom edges. These recesses 13 have multiple purposes, such as suspending curtains or other elements from the bottom edge, suspending a cover textile around the curved outer side of the frame profile 4, etc.

[0071] As can be seen the outer frame profile 4 is formed of a frame body 30 with the smooth outer surface 8 and an inner surface 31. Upper and lower flange 32, 33 extend from the inner surface at the top and bottom edges of the frame body.

[0072] The inner surface 31 and the upper and lower flanges 32, 33 define a channel 34 extend along the outer frame profile in parallel to the recess 10. The channel is configured to receive an end 6 of the main runner 6. As the main runner may be provided in standard lengths and cut to correct length during installation the channel 34 may conceal the jagged ends 6 from being seen but also reduce the risk of cutting during handling and installation of the acoustic ceiling island platform.

[0073] The length of the frame body 30, is such that it covers the whole height of the inner construction, i.e. the carrier profiles 5, the main runners 6 and the ceiling tiles 7. Thus, when viewing the installed acoustic ceiling island the smooth outer surface of the outer frame profile 8 will provide a visually pleasing finish where the edges and parts of the inner construction are hidden.

[0074] FIG. 3 shows a perspective view of a part of the outer frame profile 4 forming an outer frame of the ceiling island, the attachment clip 12, and an end of the main runner 6.

[0075] The attachment clip 12 is attached to the outer frame profile by the nut 14 and the bolt 16, and the wings 20 positioned in the first recess 10 keep the orientation of the attachment clip 12.

[0076] A lower part of the attachment clip 12 has jaws 40 surrounding an oblong opening 42 for receiving a bulb 44 of the main runner 6. The jaws 40 have teeth 46 for retaining the bulb 44. In a preferred way of mounting the attachment clips 12 are first attached to the outer frame profile 4 (and to the carrier profiles 5) and then the bulb 44 is slid into the oblong openings 42 of the attachment clips 12 by a horizontal movement of the main runner 6. Alternatively, the bulb is pressed into the oblong openings 42 of the attachment clips 12 by a vertical movement of the main runner 6. The teeth 46 may have second chamfers 48 so that the bulb 44 can more easily be pressed into the oblong opening 42. Since the jaws 40 are long and thin (that the jaws are narrow helps, too), the teeth 46 can flex so that the bulb 44 can more easily be pressed into the oblong opening 42 passed the teeth if the attachment clip 12 and the main runner 6 are not perpendicular to each other but form an angle that is something like between 60 and 80. As an alternative, the attachment clip 12 and the main runner 6 may be connected to each other before the attachment clip is connected to the outer frame profile 4 (or to the carrier profiles 5), so that the small attachment clip can be rotated in relation to the main runner 6 to the right angle, where the main runner can easily be inserted into the oblong opening 42.

[0077] In the shown embodiment, the attachment clip 12 is provided with a sideways extending arm 50 with an opening 52 at the end. The arm may be bent towards the upper part or the bulb 44 of the main runner 6 and secured to the main runner by a self-tapping screw (not shown) through the opening and into the main runner or the bulb. In that way, the main runner is secularly attached and cannot accidentally slide out of the connection with the attachment clip.

[0078] The attachment clip and the main runner can be attached to each other in other ways, e.g. by being screwed together.

[0079] FIG. 4 shows a cross-section of the carrier profile 5 in the form having a first recess 64 and a second recess 66 opposite and parallel to the first recess. The attachment clip 12 is the same as presented in FIGS. 2 and 3 and attached to the first recess 64 of the carrier profile in the same way as the attachment clip 12 in FIGS. 2 and 3 is attached to the first recess 10 of the outer frame profile 4. The attachment clip is attached to the bulb 44 of the main runner 6 in the same manner as in FIGS. 2 and 3.

[0080] Another attachment clip (not shown) can be attached to the second recess 66 in the same way as the attachment clip 12 is attached to the first recess 64. With one attachment clip connected to the first recess and another attachment clip connected to the second recess, ends of two main runners can be positioned in the continuation of each other where the ends of the two main runners will meet each other without any lateral displacement.

[0081] The ceiling island can be attached to a structural ceiling (not shown) by e.g. wires like a suspension cable set 68 attached by a second bolt 70 and a second nut 72, where a second head 74 of the second bolt is positioned and retained in a third recess 76 of the carrier profiles 5.

[0082] Angle brackets 78 are connected, e.g. by bolts and nuts, to the first recess 10 of the outer frame profile 4 as well as to the first recess 64 and the second recess 66 of the carrier profile 5 for connecting the outer frame profile 4 and the carrier profile 5 to each other.
