The elongate member is selectively movable between a raised, substantially vertical storage position residing close to the door, and an active, downwardly angled position in which the other end is in firm contact with the floor. I advantageously utilize a spring bias arrangement serving to hold the other end of the elongate member in such position of firm contact with the floor.

Abstract: A hatch securing mechanisms has a base attached to a hatchway and a hasp ached to a hatch lid. The base has an apertured retainer and a pinway element, the hasp being held between the retainer and pinway element during closure of the lid. A latch pin translatable in the pinway element has an angled tip which slides against a bevelled surface of the hasp to force the hasp into tighter, locked engagement with the base. The latch pin has a helical groove segment about the pin's axis, and a stud fixed to the pinway element engages the groove segment. The interaction of the stud and groove segment effects translation of the latch pin when the pin is manually rotated. The action of the latch pin also compresses an elastically deformable seal between the door and door frame so that the seal is increasingly effective against explosive blast pressures. The invention includes a lock mechanism for keeping the latch pin in a hasp retaining position unless the pin is manually moved.
