An interlocking assembly for a dual hinged door, comprising: a first latch rotatably securable to the door at a first side of the door, the first latch rotatable between a closed position and an open position, the first latch being arranged to engage a first hinge pin (51, 57) of a frame when the first latch is in the closed position; a second latch rotatably securable to the door at a second side of the door, opposite the first side, the second latch rotatable between a closed position and an open position, the second latch being arranged to engage a second hinge pin (52, 53) of the frame when the second latch is in the closed position; a first interference member rotatably securable to the door; a second interference member rotatably securable to the door, wherein the first interference and the second interference members are positioned adjacent one another; a first latch linkage arm rotatably connected to the first latch at a first portion of the first latch linkage arm and rotatably connected to the first interference member at a second portion of the first latch linkage arm spaced apart from the first portion, such that rotation of the first latch from the closed position to the open position moves the first latch linkage arm and causes the first interference member to rotate; and a second latch linkage arm rotatably connected to the second latch at a first portion of the second latch linkage arm and rotatably connected to the second interference member at a second portion of the second latch linkage arm spaced apart from the first portion, such that rotation of the second latch from the closed position to the open position moves the second latch linkage arm and causes the second interference member to rotate; wherein, the first interference member is positioned in a path of rotation of the second interference member, blocking rotation of the second interference member, with the first latch in the open position and the second latch in the closed position. a first latch rotatably securable to the door at a first side of the door, the first latch rotatable between a closed position and an open position, the first latch being arranged to engage a first hinge pin (51, 57) of a frame when the first latch is in the closed position; a second latch rotatably securable to the door at a second side of the door, opposite the first side, the second latch rotatable between a closed position and an open position, the second latch being arranged to engage a second hinge pin (52, 53) of the frame when the second latch is in the closed position; a first interference member rotatably securable to the door; a second interference member rotatably securable to the door, wherein the first interference and the second interference members are positioned adjacent one another; a first latch linkage arm rotatably connected to the first latch at a first portion of the first latch linkage arm and rotatably connected to the first interference member at a second portion of the first latch linkage arm spaced apart from the first portion, such that rotation of the first latch from the closed position to the open position moves the first latch linkage arm and causes the first interference member to rotate; and a second latch linkage arm rotatably connected to the second latch at a first portion of the second latch linkage arm and rotatably connected to the second interference member at a second portion of the second latch linkage arm spaced apart from the first portion, such that rotation of the second latch from the closed position to the open position moves the second latch linkage arm and causes the second interference member to rotate; wherein, the first interference member is positioned in a path of rotation of the second interference member, blocking rotation of the second interference member, with the first latch in the open position and the second latch in the closed position.
