Floating connector system between ceiling and wall structure

A floating connector system for airtight sealing between a ceiling structure and a wall structure, said system comprising

• an elongate channel member having a generally U-shaped cross section, said channel member comprising two substantially parallel, spaced sides extending from a base section;
• means for attaching the elongate channel member to the ceiling structure such that said elongate channel member is supported by the ceiling structure and forms a continuous, airtight seal with the ceiling structure, with the base section of said elongate channel member being located adjacent to the ceiling structure and with the spaced sides of said elongate channel member extending downwardly from the base section;
• an elongate cap member having two substantially parallel spaced side plates and a base plate which interconnects the upper edges of said side plates, said base plate extending at its opposing edges laterally beyond the respective side plates, but having a width less than the interior width of the channel member, thereby enabling free, uninhibited vertical movement of the elongate cap member within the channel member;
• means for attaching the elongate cap member to the wall structure such that said spaced side plates form the top side edges of said wall structure and said base plate forms the top end of said wall structure;
• said base plate and at least a portion of said spaced side plates of said elongate cap member being received within said elongate channel member, with said spaced side plates of said cap member being spaced in flatwise orientation from said spaced sides of said channel member;
• and
• a pair of elongate, elastomeric seal members positioned between the respective spaced side plates of said cap member and said spaced sides of said channel member, whereby said seal members make an airtight seal between said cap member and said channel member and whereby said seal members further isolate said cap member and its associated wall structure from transmission of vibration from said ceiling structure;
• said seal members being partially retained between the respective side plates of the cap member and spaced sides of the channel member by the extending edges of the cap base plate which block escape of the elastomeric seal members.
