ABSTRACT:
An air flow register comprises a housing which is open at upper and lower ends and comprises a peripheral outwardly projecting flange at the upper end and a skirt portion which depends from the flange, the register further comprising a cowl which is pivotally mounted in the housing and which carries a plurality of spaced inclined air deflection vanes, the cowl being pivotable between a first position in which the cowl is raised to direct air from the register across a surface in which the register is located and a second position in which upper edges of the air deflector vanes extend substantially flush with the flange and in which the cowl abuts the housing skirt portion to close air flow through the cowl.
