Abstract

A clip is disclosed for securing sound absorbing panels or the like to supporting structures. The clip has a wall plate, a projection extending outwardly from the wall plate and at least two securing members at the end of the projection opposite the wall plate, with the securing members each extending further in one direction from the projection than their extension from the projection in the opposing direction.

A sound absorbing system is disclosed and includes a supporting structure, clips, as defined above, attached to the supporting structure, and sound absorbing panels attached to the clips. The sound absorbing panels comprise a sound absorbing panel with a frame extending around the exterior perimeter of the panel, and the frame has a plurality of openings for accepting the securing members. The securing members are placed into the openings to attach the sound absorbing panels to the supporting structure.

Claims

1. A sound absorbing structure comprising the combination of a supporting structure, clips attached to the supporting structure, and sound absorbing panels attached to the clips,

wherein said sound absorbing panels comprise a sound absorbing material with a frame extending around the exterior perimeter of the material, said frame having a plurality of openings for accepting a securing member, and

wherein said clips each comprise a wall plate, a projection extending outwardly from the wall plate, and at least two securing members integrally attached between their ends to the end of the projection opposite the wall plate, said securing members each extending further in one direction from the projection than their extension from the projection in the opposing direction, with a surface of the longer side having a depressed indentation therein spanning the width of the longer side, and located thereon at a distance from its attachment at the end of the projection equal to the extension on the other side of the projection;

and

said wall plates clips being attached to said supporting structure and said openings of the frames of the sound absorbing panels engaging the securing members to affix the sound absorbing panels to the supporting structure.

2. A structure as in claim 1 wherein the openings on the frame of the sound absorbing panel are disposed near the corners of the frame to enable adjoining panels to be engaged by a single clip.

3. A structure as in claim 1 wherein the openings are sufficiently interior to the edge of the frame member to prevent the clip from extending beyond the edge of the panels.

4. A structure as in claim 1 wherein the openings in the frame are in at least two rows with one row of openings near the front of the panel and the other row of openings near the rear of the panel.

5. A structure as in claim 4 wherein at least one of the panels is offset from the other panels by some of the panels being attached by securing members engaging the front row of openings and other of the panels being attached by securing members engaging the rear row of openings.

6. A structure as in claim 1 wherein the sound absorbing panels comprise a sound absorbing material completely enclosed in a heat shrunk plastic material.

7. A structure as in claim 6 wherein the sound absorbing panels have a perforated facing material on at least one face.

8. A structure as in claim 6 wherein the projection on the clip is perpendicular to the wall plate and the securing members on the clip are perpendicular to the projection.

9. A structure as in claim 8 wherein the securing members on the clip are flat plates.

10. A structure as in claim 8 wherein the securing members on the clip are round rods.
