摘要：An air handling grille with an open rectangular frame which defines twoopposing grooves each bounded by a narrow flange. A series of adjustable vanes eachwith opposite bearing studs is preassembled with elongated resilient bearing members.Each bearing member has a series of small openings to hold the bearing studs. Thebearing members are mounted on the studs during preassembly and the members arethus entered in the grooves. Each member includes a flange which is deflected inwardlyduring assembly and thereafter latches the bearing members in assembled position. Theflanges also tend to twist the bearing members restricting bearing openings therein andfrictionally retaining the studs. A second series of vanes is supported by a pair of crossmembers. Spring clips secure the vanes on engagement with ends of the cross members.
