Abstract
An air deflector arrangement (100) is disclosed and adapted for use in ceilings and similar areas for selectively providing discrete air flow patterns in radial directions relative to the arrangement (100). The air deflector arrangement (100) comprises a perforated face (102) typically mounted in a downwardly-disposed configuration and coplanar with adjacent ceiling panels or the like. The face is latched or otherwise releasably connected to a somewhat frustum-shaped back panel (110) extending upwardly from the plane of the ceiling panels. A plurality of deflector blades (140) are pivotably secured to an eyelet fastener (160) connected at a central location on the face (102). Each of the deflector blades (140) is freely rotatable throughout a 360.degree. range of motion relative to each of the other blades. Selective blade configurations provide an infinite number of air flow patterns. The blades (140) are of a substantially optimum shape and size so as to produce distinct radial air flow patterns, while correspondingly maintaining sufficient 'open areas' so as to minimize static back pressures.
