<p><P>PROBLEM TO BE SOLVED: To improve a wind direction changing effect by always moving right/left blades of a wind direction changing device to a mainstream of blast while automatically changing an angle. <P>SOLUTION: The wind direction changing device comprises a sliding shaft B32 concentric with rotary shafts 27 of upper/lower flaps 12, a right/left blade drive mechanism 33 connected to the sliding shaft B32, a supporting bar 15 having a fitting hole 17 which supports sliding shafts A31 and blade shafts 18 of the right/left blades 14 for supporting the right/left blades 14, and a connection bar 16 for connecting fixing shafts 20 of a plurality of the right/left blades 14 and rotating the shafts around the rotary shafts 27. A link A34 is rotatably held by the sliding shaft B32 and slidably and rotatably connected to the sliding shaft A31. A link B35 which slidably and rotatably moves on the sliding shaft A31 simultaneously with the sliding of the link A34 is provided, and the link B35 is engaged with the connection bar 16. The sliding shaft B32 is moved to right/left directions by the right/left blade drive mechanism 33, the connection bar 16 is moved to right and left by sliding the link A34 and the link B35, and angles of the right/left blades 14 are automatically changed to the right/left directions. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
