DOOR AND PANEL LATCH APPARATUS FOR DECOMPRESSING WITH OPENABLE AND CLOSABLE DECOMPRESSING APERTURE

摘要

[Problem] The opening and closing of a door having a pressure reducing opening that can be opened and closed is facilitated. [Resolution] The door main body 10, the pressure reduction panel 22 which is attached so as to be displaceable between the pressure reducing opening closing position and the pressure reducing opening opening position, the door 30 by the rotation operation of the handle 30 and the handle. A door latch device 26 attached to the door body 10 and a swinging member fixed to the handle shaft 28, having a latch bolt 32 for the door body that is displaceable between the locking position and the door unlocking position. When the 38 and the pressure reducing panel 22 are in the opening for closing the pressure reducing position, the displacement can be made between the panel locking position and the panel unlocking position in conjunction with the swinging of the swinging member 38 around the handle shaft 28. A door having an opening and closing pressure reduction opening having a pressure reduction panel latch device attached to the door main body, the door having a pressure reduction panel latch bolt (42).
