Document Type and Number:
Japanese Patent JP2810388
Kind Code:
B2
Abstract:
PURPOSE:To automatically execute opening without fail when a temperature in a room is increased by providing an opening part to be closed with the oriented sheet, which is highly drawn, of thermoplastic resin and shrinking the said sheet at the time of heating. CONSTITUTION:For the oriented sheet which is highly oriented, uniaxial orientation or biaxial orientation is executed. Then, the sheet is oriented to be >=twice, preferably three times in an area ratio and the opening part is formed by using this sheet. For example, a sheet 12 to be highly oriented of the thermoplastic resin is fixed as an emergency refuge port (opening part) by a hinge 13 and a projection 14 between walls 11. A spring is fitted to the hinge 13 and force to open the port is always operated. When the room temperature is increased by fire, etc., in the room, the oriented sheet 12 is shrunk and separated from the projection 14. Then, the oriented sheet is automatically opened in an outer direction and the opening is executed. In such a case, it is preferable to use a highly biaxially oriented acrylic sheet as the oriented sheet.
