AUTOMATIC DOOR FOR FREIGHT CAR
PROBLEM TO BE SOLVED: To provide an automatic door for a freight car that allows an inoperable sliding door to be released readily and surely at a time of emergency, and furthermore to be restored readily.SOLUTION: An automatic door for a freight car includes an opening/closing drive part 1 comprising a first arm 2 rotated in a circular arc by a drive motor 4, a second arm 3 rotated in a circular arc around a second center of rotation P2 at a tip of the first arm 2, and a first timing pulley 5 fixed at a first center of rotation P1 of the first arm 2, and furthermore a first arm rotation angular adjustment structure 31. When the drive motor 4 is electrically inoperable, the first arm 2 is rotated around the second center of rotation P2 as a tip part of the second arm 3 moves linearly, when a sliding door is moved manually. Consequently, a rotary shaft of the drive motor 4 is rotated by force, enabling the sliding door to be opened/closed manually.SELECTED DRAWING: Figure 8
【課題】緊急時に動作不能状態のスライドドアを解除するときに、容易かつ確実に緊急解除することができ、更に容易に復帰することができる貨物車両用自動開閉ドアを提供する。【解決手段】駆動モータ４で円弧状に回動する第１アーム２と、第１アーム２の先端を第２回動中心点Ｐ２として円弧状に回動する第２アーム３と、第１アーム２の第１回動中心点Ｐ１に固定した第１タイミングプーリ５とから成る開閉駆動部１と、第１アーム回動角調節構造３１と、を備え、駆動モータ４が電気的に動作不能状態になったときに、スライドドアを手動で動かすことにより、第２アーム３の先端部の直線移動に伴い、第１アーム２を第２回動中心点Ｐ２で回動させ、駆動モータ４の回転軸を強引に回動させ、スライドドアを手動でも開閉することができる。【選択図】図８
