DOOR INCLUDING OPENABLE/CLOSABLE OPENING FOR DECOMPRESSION AND PANEL OPENING/CLOSING OPERATION DEVICE

摘要

To open/close a panel for decompression with a rotation operation of a handle.SOLUTION: A door including openable/closable opening for decompression includes: a door body (18); a panel (22) for decompression; a door latch device (26); a latch device (27) for a decompression panel; and a panel opening/closing operation device (29). When the latch device (27) for the decompression panel displaces a latch bolt (42) for the decompression panel to a panel release position in accordance with displacement of a latch bolt (32) for the door body by rotation of a handle shaft (28), the panel opening/closing operation device (29) displaces the panel (22) for decompression from a closing position of the opening for decompression to an opening position of the opening for decompression interlockingly with further rotation of the handle shaft.SELECTED DRAWING: Figure 2
