US Patent 8966821 Dual hinged door mechanism

An interlocking assembly for a dual hinged door, includes a first latch and second latch each rotatably secured to opposing sides of the door. Each Latch is linked to a first and second interference member respectively, such that positioning the first latch in an open position rotates first interference member in a path of rotation of the second interference member. In that configuration, second interference member is not permitted to rotate and prevents the second latch from opening.
