A door closing mechanism for a two-panel door having a leading panel and a trailing panel disposed adjacent to one another and being hingedly connected to a door frame. The door closing mechanism controls the closing sequence of a leading panel and a trailing panel, such that a trailing panel is locked in an open position prior to the closing of a leading panel. A locking mechanism, for locking and unlocking the trailing panel, includes a pivoting member which interacts, inter alia, with a sliding block and release member, for pivotally locking and unlocking a locking device. This locking mechanism pivots the pivoting lever into a locking position for preventing the closure of a trailing panel in advance of a leading panel upon a leading panel moving from a closed position to an open position. This locking mechanism can also pivot the pivoting lever into an unlocking position for permitting positioning of a trailing panel into a closed position upon a leading panel being in a closed position. This door closing mechanism can further be designed for concealment within the guide rail and leading and trailing panels.
