摘要： PROBLEM TO BE SOLVED: To provide a fireproof door which can be opened/closed by reducing a force acting on a latch mechanism, even when fire-extinguishing gas is jetted inside a room and high pressure is applied to the fire door. SOLUTION: The fire door A which is installed openably/closably so as to communicate/divide a room R1 in which the fire-extinguishing gas is jetted at fire occurrence and an outside space R2, such as a corridor, includes door bodies 8, 9 where door tails 8a, 9a are supported by a door frame 7 installed on the peripheral edge of a door opening portion 6 so as to be rotatable around a pivoting axis line extending in the height direction T1, and the latch mechanism 4 which is installed so as to be incorporated in the door ends 8b, 9b of the door bodies 8, 9, locks the door bodies 8, 9 when the door bodies 8, 9 are closed, and releases the locked state of the door bodies 8, 9 by operating a knob. The door bodies 8, 9 is provided with thick portions 10, formed by enlarging the thickness B1 of the door bodies 8, 9, at the door ends 8b, 9b containing the latch mechanism 4.

摘要： PROBLEM TO BE SOLVED: To facilitate opening of a door by preventing the door from being intermeshed or locked, even when a room interior is brought into a high pressure state. SOLUTION: This door unlocking device 24 includes a latch 35 and a strike 40 provided in the doors 21 and 22. The latch 35 includes a latch bolt 36 capable of being engaged with/disengaged from the strike 40, and a coiled spring 37 which is provided on the base side of the latch bolt 36. High pressure in a room 5 is applied to a space of the strike 40 through a pressure leading path 41 from an opening 42 in the door 22. The latch bolt 36 engaged with the strike 40 recedes while compressing the coiled spring 37 under the high pressure introduced into the strike 40, so as to be disengaged from the strike 40. Thus, the doors 21 and 22 are brought into an unlocked state before deformation, even when the inside of the room 5 is filled with high-pressure gas. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a jet head capable of reducing the noise based on the supply of fire extinguishing gas, and to provide a gas fire extinguishing system equipped with the same. SOLUTION: The jet head 41, connected to the outflow port of supply piping 22c for supplying the fire extinguishing gas into a target chamber to eject the fire extinguishing gas flowing through the supply piping 22c. The jet head includes: a first gas passage 61 also used as expansion chambers 63, 64 and 65 through which the fire extinguishing gas supplied from the outflow port of the supply piping 22c flows; and a second gas passage 62 also used as expansion chambers 68 and 69, wherein the jet head is further provided with the gas jet port 66 communicating with the first gas passage 61 and the gas jet port 70 communicating with the second gas passage 62, on the front walls 45 being the respective closed ends of the leading ends of the respective gas passages 61 and 62.
