Bar lock mechanism

A bar lock mechanism for releasably securing a door in a closed position wherein said door extends across an opening defined by a walled enclosure, with said door being swingable about a generally vertical axis disposed adjacent a first vertical marginal edge of said opening and having a lock carried thereon, said bar lock mechanism comprising:

• an elongated member defining an elongated axis extending between opposed ends thereof and about which said bar lock mechanism swingably moves;
• a manually operated locking handle connected to and about midlength of said elongated member, said handle being connected to said member for rotation about an axis extending generally normal to said elongated axis whereby allowing said handle to be manipulated into an operable locking relation with said lock on said door;
• and
• hinge structure operably associated with the opposed ends of said elongated member for pivotally securing said bar lock mechanism to the walled enclosed adjacent a second vertical marginal edge of said opening, said hinge structure including a pair of axially spaced hinge pieces, with one hinge piece being disposed in operable association with each end of said elongated member, and with each hinge piece being configured to secure a respective end of said elongated member for rotation about said elongated axis whereby allowing said bar lock mechanism to swingably move toward and away from the door.
