Air conditioner register

Abstract

An air conditioner register for adjusting the direction of air is provided. The register includes a retainer, which defines an air duct therein, and a barrel, which is pivotally supported in the retainer. The retainer includes a rectangular air outlet of the duct. The barrel includes two or more long fins extending in the direction of long sides of the outlet. The long fins that are located closest to the long sides of the outlet, among the long fins located in the outlet when the barrel is in a neutral state, form a pair of main long fins. Walls of the retainer including the long sides of the outlet include bulging portions. When the barrel is tilted to a maximum tilt position of its movable range, one of the bulging portions is located close to the downstream end of the main long fin that leads in the tilt motion.

1 . An air conditioner register for adjusting the direction of air-conditioning air, comprising:
 a tubular retainer including an air duct for air-conditioning air defined therein by a pair of first walls facing each other and a pair of second walls facing each other, wherein the retainer includes a rectangular air outlet at a downstream end of the air duct, and the air outlet includes a pair of short sides facing each other and a pair of long sides facing each other, and wherein each of the first walls includes one of the short sides of the air outlet, and each of the second walls includes one of the long sides of the air outlet; and   a barrel including two or more long fins extending in a direction of the long sides in the retainer and arranged along the short sides separate from and parallel to each other, wherein the barrel includes a pair of barrel support shafts extending in the direction of the long sides on both sides of the barrel, and the barrel is pivotally supported by the barrel support shafts at part of the first walls close to the air outlet, wherein   when the barrel is arranged in a barrel neutral state, in which the long fins are arranged parallel to the second walls, the long fins located closest to the long sides, among the long fins located in the air outlet, form a pair of main long fins, and   each of the second walls includes a bulging portion, which bulges inward of the air outlet, and when the barrel is tilted to a maximum tilt position in a range of the tilt motion, one of the bulging portions is located close to the downstream end of a one of the main long fins that leads in the tilt motion.   
     
     
         2 . The air conditioner register according to  claim 1 , wherein
 the long fins of the barrel further include a pair of sub-long fins in addition to the main long fins, and   when the barrel is arranged in the barrel neutral state, the sub-long fins are arranged at positions outward of the air outlet in the retainer.   
     
     
         3 . The air conditioner register according to  claim 2 , wherein
 the sub-long fins are arranged at positions close to the second walls, and   the downstream ends of the sub-long fins are located upstream of the downstream ends of the main long fins.   
     
     
         4 . The air conditioner register according to  claim 1 , further comprising
 a plurality of short fins in the retainer, wherein the short fins extend in the direction of the short sides and arranged along the long sides in a state separate from and parallel to each other, wherein each of the short fins includes at least one short fin support shaft, which extends in the direction of the short sides, and wherein each of the short fins is pivotally supported by the associated short fin support shaft, wherein   at least parts of the short fins are arranged in the barrel, and the short fin support shafts of the short fins are supported by the barrel, and   the short fins are further coupled to each other by a coupling rod.   
     
     
         5 . The air conditioner register according to  claim 4 , wherein
 the short fins are formed to be longer than the main long fins in the flow direction of the air duct in a state in which the short fins are arranged parallel to the first walls, and   one third or more of the length of the short fins in the flow direction of the air duct is arranged in the barrel.   
     
     
         6 . The air conditioner register according to  claim 4 , wherein the downstream ends of the short fins are arranged at positions close to the downstream ends of the main long fins.
