Abstract An air intake grille has an air flow guide member mounted on a housing in such a manner that the direction of air flow can be adjusted using a control member. The air flow guide member is constituted by a sheet assembly formed by laminating a multiplicity of perforated sheets. The sheet assembly is retained by retainers in such a manner that the sheets can slide so as to be stepwisely offset from each other. Further, the sheet assembly is mounted on the housing in such a manner as to be pivotal with respect to a fixed plane, which is the front surface of the housing, or a fixed plane parallel to the front surface. The air intake grille with the above arrangement enables the air flow guide member to be orientated to any desired direction in a single operation of the control member. Since the housing is not split into front and rear portions and the air flow guide member can be handled as an integrated sheet assembly, it is possible to reduce the time and labor required for manufacturing and assembling the air intake grille.
An air intake grille having an air flow guide member mounted on a housing in such a manner that the direction of air flow can be adjusted using a control member, said grille comprising: (a) said air flow guide member being formed by alternately laminating first and second sheets, each of said first sheets having a plurality of horizontally elongated bores disposed parallel to each other vertically and further having a drive pin-receiving bore in its center and connecting pin-receiving bores at both lateral end portions thereof, each of said second sheets having a plurality of vertically elongated bores disposed parallel to each other horizontally and a vertically elongated guide slit formed in its center and possessing a height which enables the second sheet to slide horizontally along the upper and lower inner walls of said housing, said connecting pin-receiving bores respectively receiving a pair of connecting pins which are capable of being supported horizontally, and said air flow guide member being clamped between a fixed grille member provided at the front surface of said housing and a rear retainer which is retained by said housing so as to be immovable in the longitudinal direction of said housing; and (b) said control member being supported by said fixed grille member through a pair of opposing spherical surfaces, said control member having a drive pin received through said drive pin-receiving bore and vertically elongated guide slit formed in the respective centers of said first and second sheets.
