ABSTRACT:
A double hinge locking system mounts and secures a series of two-way opening covers or similar members. Each hinge/lock component of the system provides a combination hinge pivot and associated lock that operate on a common axis, and includes a locking device in which fixed and rotary locking parts are presented by fixed and movable saddles coaxial with the hinge axis and relatively rotatable about such axis between locked and unlocked conditions. An interlock mechanism interconnects locking devices on opposite sides of the hinged member to prevent double unlocking. Additionally, a passive safety lock is provided by the cooperating saddles to prevent separation of the member from its mounts in the event that double unlocking inadvertently occurs.
