Sound insulating panels

Claim 1

An improved sound insulating panel assembly having a sound insulating core defining a pair of opposed major surfaces extending between a pair of opposite vertical edges, each vertical edge having a channel-like frame member extending along the height thereof, an extruded profile having a semi-cylinderical outer surface releasably supported in each respective channel-like frame member, the semi-cylinderical outer surface having a radius of curvature between 15 and 35 mm, and the profile having a height of at least 800 mm, each extruded profile having a pair of inwardly directed flanges which terminate in rearwardly extending gripping means, cooperating bent portions on the channel-like frame members engaging the gripping means, the width of the insulating core being substantially equal to the corresponding dimension of the channel-like frame members; fabric stretched over the major surfaces of the panels, forced over the flanges of the frame members and adhesively secured thereto, the inwardly directed flanges of the profiles having shoulder portions accomodating ends of the fabric between the shoulder and adjacent surfaces of the channel-like frame members and concealing ends of the fabric from view while preventing accidental removal thereof from the panel; and meshingly-engagable, connecting-tapes mounted on the respective outer radiused surface of said profiles, said connecting-tapes being releasably-engagable with a complementary connecting-tape on a second structure for assembling the sound insulating panel and said second structure, the two connected tapes at said profile defining a sound-absorbing connection between the panel and said second structure and minimizing sound transmission therebetween, the core being secured to the frame members by fastening means, each pair of complimentary tapes respectively including releasably-engagable mushroom-like sections and meshing portions.
