HATCH FOR EVACUATION
To provide a hatch for evacuation in which a rate of occurrence of defective products can be lowered even if the size management in the manufacture is not performed strictly.SOLUTION: An opening/closing member 2 swingably provided at an upper lid 1 is made movable elastically. Also, a hook member 13 provided in the side of a hatch body H is constituted by a hook piece 13a, a fixing part 13b and an elastic part 13c of these intervals. The elastic movement of the opening/closing member 2 is combined with the elastic movement of the hook piece 13a, and a dimension error collected in a relative position between a first hook 2b and the second hook 13a is allowed to be absorbed.SELECTED DRAWING: Figure 3
【課題】 製造時の寸法管理を厳密にしなくても、不良品の発生率を低くできる避難用ハッチを提供すること。【解決手段】 上蓋１に揺動可能に設けられた開閉部材２を弾性的に移動可能にするとともに、ハッチ本体Ｈ側に設けた引掛け部材１３を、引掛け片１３ａと、固定部１３ｂとこれらの間の弾性部１３ｃとで構成して、開閉部材２の弾性的な移動と上記引掛け片１３ａの弾性的な移動とが相まって第１の引掛け部２ｂと第２の引掛け部１３ａとの相対位置に集約された寸法誤差を吸収できるようにした。【選択図】 図３
