Patent ID: 8327905

Claim:
A vertically folding wall partition adapted to close an opening comprising a plurality of interconnected horizontal wall panels pivotally interconnected to one another and forming horizontal panel joints therebetween, said panels being actuably secured by an overhead lifting mechanism to displace said panels from a folded storage position, wherein the opening is unobstructed, to a deployed partition forming position, wherein the opening is closed by the wall partition, said wall panels each having two opposed composite walls which, when in the deployed position, are spaced-apart by a substantially unobstructed air gap therebetween, said composite walls having side edge perimeter seals to provide acoustic sound damping; each said composite wall having a face sheet secured to a front face of a core material, a backer sheet secured to a rear face of said core material and an insulation material secured to said backer sheet facing said gap; said vertically folding wall partition having a top and bottom horizontal seal, an acoustically obstructing joint obstructing member disposed between said horizontal panel joints when said panels are in said deployed position, said composite walls, side edge perimeter seals, said top and bottom horizontal seals and said joint obstructing members in combination provide improved acoustic performance for said vertically folding wall partition.
