A device (100) for closing a room opening includes a frame (102), at least one leaf (104), a deformable and/or moveable sealing member (114) and a sealing member actuation device (120). The frame (102) is adapted to be set in a reveal of a room opening, the leaf (104) being movably arranged relative to the frame (102) so as to move relative to the frame from an open to a closed position in which there nonetheless exists between the frame (102) and the leaf (104) a gap (112). The sealing member (114) is disposed at least substantially within the gap (112). The sealing member (114), when not pressurized, does not drag against an adjacent component of the device which is moving relative thereto when the room opening is opened or closed. The sealing member (114) is actuated by the actuation device (120) when the device is in a position suitable for actuation of the sealing member (114) so as to better ensure that the sealing member (114) does not drag against the adjacent component until desired. The sealing member actuation device (120) is arranged in the frame (102) and/or in the leaf (104), thereby permitting installation of the device without the need for a separate fluid pressure source. |
