A concealed hinge for use with a lightweight safe having a door, said hinge comprising: a bearing means; a pin member positioned slidably on top of said bearing means so as to ride thereon, the central longitudinal axis of said pin member defining a pivotal axis for said hinge; a mounting bracket adapted to be mountable on the interior of said safe, said bracket possessing a cavity and a first access opening and a second access opening which communicate with said cavity, said second access opening being dimensioned and positioned to permit a sliding insertion and sliding retraction therethrough of said pin member and said bearing means, said cavity slidably receiving and rotatively embracing, said bearing means and a portion of said pin member whereby said pin-like member is free to rotate about said pivot axis and within said cavity, independently of said mounting bracket; said pin member extending through said first access opening; sealing means for manually sealing and unsealing said second access opening, said sealing means including: an axially threaded female socket configured within said second access opening, and an axially threaded male connector plug dimensioned to interact with said female socket to form a manually releasable and adjustable seal for said second access opening; wherein upon said plug being removed from said socket, said bearing means and said pin member are discharged from said hinge through said second access opening by the force of gravity; a second retaining means which slidably receives and rotatively embraces a portion of said pin member; wherein said pin member is free to rotate about said pivotal axis independently of said mounting bracket; and a leaf member generally shaped in an approximately “J”-shape cross-section, said leaf member being securely mounted on said second retaining means, said mounting permitting said leaf member to pivot around the pivotal axis of said hinge.
