Abstract
Abstract An acoustic assembly has sound absorbing panels held in place by U-shaped connectors having oppositely disposed lips that extend parallel with and bear against flanges on the panels. A bolt extends through one connector and into the next connector where it enters a socket. Tightening of the bolt draws the connector lips against the panel flanges thus tightening the assembly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
An acoustical assembly comprising two laterally opposite, sound absorbing panels and two connectors between them, each said panel embodying two face portions spaced from each other, two side portions extending from said face portions towards each other and two flange portions extending from said side portions angularly and positioned alongside and adjacent each other, sound absorbing material between said two face portions, said connectors each embodying two legs and a bridge member between and connecting said legs at one end, said legs each having a lip portion at the other end extending inwardly towards each other and respectively contacting said fLange portions, a first said connector bridge member having a hole therethrough, a bolt receiving member in a second said connector, a bolt extending through said hole and adapted to connect with said receiving member to thereby draw said lips of each connector towards each other and firmly against said flanges.
Claim 2
Dependent Claim
151 words
An acoustical assembly comprising two laterally opposite, sound absorbing panels and two connectors between them, each said panel embodying two face portions spaced from each other, two side portions extending from said face portions towards each other and two flange portions extending from said side portions angularly and positioned alongside and adjacent each other, sound absorbing material between said two face portions, said connectors each embodying two legs and a bridge member between and connecting said legs at one end, said legs each having a lip portion at the other end extending inwardly towards each other and respectively contacting said fLange portions, a first said connector bridge member having a hole therethrough, a bolt receiving member in a second said connector, a bolt extending through said hole and adapted to connect with said receiving member to thereby draw said lips of each connector towards each other and firmly against said flanges.
Claim 3
Dependent Claim
19 words
An acoustical assembly as of claim 1, said bolt receiving member being fixed to said second connector bridge member.
Claim 4
Dependent Claim
19 words
An acoustical assembly as of claim 1, said bolt receiving member bearing against said lips of said second connector.
Claim 5
Dependent Claim
21 words
An acoustical assembly as of claim 3, and sound absorbing material between said receiving member and said second connector bridge member.
Claim 6
Dependent Claim
45 words
An acoustical assembly as of claim 1, and a U-shaped support within said second connector embodying two legs and a bridge member between them, said latter legs contacting said lips of said second connector, said bolt receiving member being fixed to said support bridge member.
Claim 7
Dependent Claim
30 words
An acoustical assembly as of claim 5, said support being spaced inwardly from said second connector bridge member, and sound absorbing material between the latter and said support bridge member.
Claim 8
Dependent Claim
23 words
An acoustical assembly as of claim 1, said connector lips having compressible coating material at the surfaces in contact with said panel flanges.
Claim 9
Dependent Claim
23 words
An acoustical assembly as of claim 5, said bolt receiving member being integrally united to the inner surface of said support bridge member.
