PROBLEM TO BE SOLVED: To provide a hatch sticker which allows inhabitants or residents to readily open an upper lid of an evacuation hatch in an emergency and prevents an unnecessary opening and vibration of the upper lid due to phenomena such as strong wind in normal time.SOLUTION: In a newly provided hatch 1, a ladder 5 is folded and stored in a hatch body 2 and an upper lid 3 and a lower lid 4 are closed in normal time. Since the upper lid 3 can be pressed to the hatch body 2 by sticking hatch sticking stickers 20 and 30 to both the upper lid 3 and the hatch body 2 while the upper lid 3 is in close contact with the hatch body 2, the upper lid 3 is not opened even when a strong wind blows.SELECTED DRAWING: Figure 6 |
