Abstract:
1. A door arrangement for a ship, comprising: a doorway frame bounding a doorway opening, wherein opposite first and second frame edges of said doorway frame respectively have first and second bars that respectively extend longitudinally along said first and second frame edges and along said doorway opening, and wherein said first bar is a movable first bar; a door movably mounted by a hinge arrangement to said doorway frame, such that said door is movable between an open position and a closed position in which said door respectively opens and closes said doorway opening, wherein opposite first and second door edges of said door respectively have therein first and second grooves that extend longitudinally along said door edges and that are configured to receive at least partly therein said first and second bars when said door is in said closed position; a latching mechanism that is connected to said movable first bar and is adapted to move said movable first bar into a latched position in said first groove and into an unlatched position out of said first groove when said door is in said closed position so as to respectively latch and unlatch said door in said closed position; a locking rod that is arranged parallel to said movable first bar and parallel to said first frame edge in or on said doorway frame; a manually operable locking lever that is drive-connected to said locking rod so as to move said locking rod parallel to a longitudinal extension direction of said movable first bar; and a locking coupling that couples said locking rod with said movable first bar so as to lock and unlock said movable first bar in said latched position thereof dependent on a position of said locking rod; wherein said locking lever is drive-connected to said locking rod by an arrangement in which a portion of said locking rod comprises a toothed gear rack, said locking lever is a pivotable lever and comprises a lever handle, a lever shaft extending from said lever handle, and a gear wheel connected to said lever shaft and engaged with said toothed gear rack; wherein said locking coupling comprises: a guide block having a first guide channel and a second guide channel therein; and a locking pin connected to and extending from the movable first bar; wherein: said first guide channel and said second guide channel intersect one another in said guide block; said locking rod is slidably received in said first guide channel so that said locking rod is slidable between a locked position and an unlocked position; said locking pin is slidably received in said second guide channel so that said locking pin is slidable together with said movable first bar between said latched position and said unlatched position; when said locking pin is in said latched position and said locking rod is in said locked position, said locking rod blocks said second guide channel and thereby blocks said locking pin against sliding from said latched position to said unlatched position; and when said locking rod is in said unlocked position, said locking rod unblocks said second guide channel and thereby allows said locking pin to slide from said latched position to said unlatched position.
