Zusammenfassung: | PROBLEM TO BE SOLVED: To solve the problem that in a storage house having structure where a door is always in a rise position to close an opening part, and when the door is pushed up, the opening part is opened, the door needs to be pushed up manually when the opening part is closed after the door is lowered to open the opening part.SOLUTION: A wire 66 is taken out from a wire winding device 64 energized so as to always wind the wire 66, and the wire 66 is connected to a door 16 through a pulley 62. Consequently, after the door 16 is pushed down with a hand to open the opening part 14, when the hand is released, the wire 66 is wound by the wire winding device 64, and then the door 16 automatically rises.
【課題】扉が常には上昇位置にあって開口部を閉成し、該扉を押し上げると開口部が開放する構造の貯蔵庫では、扉を下降させて開口部を開放した後に閉成させるときは、該扉を人の力で押し上げる必要があった。【解決手段】ワイヤ66を常に巻取るように付勢されているワイヤ巻取装置64から該ワイヤ66を導き出し、このワイヤ66を扉16にプーリ62を介して接続する。これにより、扉16を手で押し下げて開口部14を開放させた後に、その手を放すとワイヤ66がワイヤ巻取装置64に巻取られ、該扉16は自動的に上昇する。【選択図】図3 |
