A locking hinge mechanism (10) that includes a hinge (10a) comprising an articulated axle (28) rotatably attached to first and second members (22,24) such that the operation of the hinge mechanism (10a) causes the members (22,24 ) to controllably move in a first or opening direction and a second or closing direction. The hinge (10a) comprises a fixed locking member (36), and a movable locking member (46) coaxially disposed relative to the fixed locking member (36). A bias mechanism (48) is coupled to the movable locking member (46) that causes it to interlockably engage the fixed locking member (b 36) such that the hinge (10a) causes the first and second members (22, 24) to freely move in one direction. A disengagement mechanism (38, 40) is coupled to the movable locking member (46) to disengage it from the fixed locking member (36) so that the first and second members (22, 24) may freely move in either direction. The hinge mechanism (10) also comprises control apparatus (34, 54) coupled to the disengagement mechanism (38, 40) which permits the first and second members (22, 24) to move in a closing direction when the locking members (36, 46) are disengaged. Furthermore, a control system (52) may be coupled to the hinge mechanism (10) that is adapted to control the deployment and retraction of the first and second members (22, 24).
