ABSTRACT:
A bar lock mechanism for releasably securing a pivoted door in a closed position relative to an opening in a walled enclosure and including an elongated shaft structure connected to the walled enclosure and defining an axis of rotation for the bar lock mechanism. A locking handle is connected to the shaft structure for rotating the shaft structure and securing the door in the closed position. A pair of axially spaced hinge pieces are adapted to be disposed at opposed end portions of the shaft structure. Each hinge piece has a base portion for allowing securement of the hinge piece to the walled enclosure and an integral portion spaced from the base portion for journalling a respective end of the shaft structure for rotation about its axis whereby allowing the bar lock mechanism to move relative to the walled enclosure.
