<p>PURPOSE:To interlock both fin groups smoothly by installing an inter-locking engaging section for interlocking the reciprocating rotational operation of at least one fin in one in group of longitudinal/lateral fin groups with the other fin group to at least one fin and mounting a section to be interlocked and engaged to the other fin group. CONSTITUTION:When a driving motor 7 is turned, a rotational member 7b is revolved in the direction C, and a lateral interlocking rod 3 is forwarded and retreated in the direction of A1-A2 by the engagement of the slot section 3b and interlocking projecting section 7c of the rod 3. Consequently, a plurality of longitudinal fins 2 connected to the lateral interlocking rod 3 are reciprocated and rotated in the horizontal direction centering around support shafts 2a respectively. A middle fin 5 in a lateral fin group is turned in the vertical direction centering around a support shaft 5a through the engagement of an interlocking engaging section 2c and a section to be interlocked and engaged 5c in the rotational operation of the middle longitudinal fin 2. That is, the interlocking engaging sections 5c are revolved to a vertical lower section when the interlocking engaging sections 5c are guided t the upward curved sections (1) of the interlocking engaging section 2c, and turned to a vertical upper section when the interlocking engaging sections 5c are guided to downward curved sections (2).</p> |
