Abstract
In a shock-secure door or hatch arrangement on marine ships, a doorway frame, on two opposite longitudinal edges thereof, has continuous latching bars that are receivable in corresponding grooves in opposite edges of a door in order to latch the door in a closed position. The latching bar on the hinged edge of the doorway frame is stationary and engages into the associated door edge groove during a closing motion of the door. The latching bar on the opposite edge of the doorway frame is movable by actuating elements so as to engage into the respective associated door edge groove for latching the door in its closed position. A locking mechanism locks and unlocks the movable latching bar in its latched position.
