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
摘要翻译：要解决的问题：即使当房间内部处于高压状态时，通过防止门互相啮合或锁定来促进门的打开。解锁方案：该门解锁装置24包括设置在门21和22中的闩锁35和冲击40.闩锁35包括能够与冲击40接合/脱离的闩锁螺栓36和螺旋弹簧 37，其设置在闩锁螺栓36的基部侧。室内的高压通过来自门22中的开口42的压力引导路径41施加到冲击40的空间。闩锁螺栓36与罢工40在被引入罢工40的高压下压缩螺旋弹簧37而后退，从而与罢工40脱离。因此，即使在内部的情况下，门21和22也处于解锁状态的房间5充满高压气体。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To forcibly open a door by adding an auxiliary force in an opening direction to the door, even when pressure inside a room becomes high and the high pressure causes biting in a lock. SOLUTION: In a door opening assist device 36, a fan 38 rotated by the difference between indoor and outdoor pressures is provided in a pressure release port 37 formed in the door 21, and electric power is generated by a power generator 40. The electric power is transmitted to a drive motor provided on the door 21, whereby a door opening assist mechanism 45 is actuated to impart the auxiliary force in the door opening direction. In the door opening assist mechanism 45, racks are formed in an operating shaft 47 rotatable around the base shaft 46 installed on a wall surface 41. The rotating power of the drive motor is transmitted to the racks by a pinion to impart a tensile force to the operating shaft 47. A battery 54 for storing electric power, when a timing lag occurs at opening the door, is connected inparallel to the drive motor by wiring 42. When the door 21 is opened, the operating shaft 47 is relatively pulled by the rotating power of the drive motor receiving the electric power from the battery 54 to impart the auxiliary force in the door opening direction to the door 21.
