The lock of the passive door blade of a double door according to the invention comprises a lock body (23), a latch (17) and a control wedge (18). The control wedge is arranged to linearly move to a position extended out from the lock and to a position retracted inside the lock. The lock additionally comprises a lever (20), a leading shaft (21) and a spring system (27). The lever (20) is rotatably attached (25) to the control wedge (18) by its first end and rotatably attached (24) to the leading shaft (21) by its second end. The leading shaft (21) is additionally rotatably attached (22) to the lock body (23) and the leading shaft comprises a control cam (26) being in connection with the latch (17). The lever (20) and the leading shaft (21) are arranged to transfer the force of the spring system (27) to the control wedge (18) so that the force parallel with the linear movement of the control wedge is at its largest in the extended position of the control wedge and at its smallest when the control wedge is in the retracted position inside the lock.

A lock system includes an active panel center gearbox. The active panel center gearbox includes a deadbolt, a deadbolt drive to extend or retract the deadbolt, an upper drive assembly, a lower drive assembly, a latch bolt, a handle assembly to retract the latch bolt and to extend or retract the lower and the upper driver assemblies, a reverse action rocker coupling the lower and the upper drive assemblies so they move in different directions, a mishandling bolt, and a mishandling plate. When the mishandling bolt extends, it lowers the mishandling plate. When the mishandling plate lowers, it engages the deadbolt to prevent the deadbolt from extending, it engages the handle assembly to prevent the lower drive assembly from extending, and it engages the reverse action rocker to prevent the upper drive assembly from extending.

A sectional door with walkway comprises a supporting structure; a main door comprising one plurality of panels constrained to the supporting structure in a movable manner between a closure position and an opening position; a pedestrian door, defined by one openable portion of each of the panels, the openable portion being hinged to a base portion of the respective panel; a locking device/structure/component/apparatus/unit or the like, positioned between the base portion and the openable portion of each of the panels; and an automatic movement device/structure/component/apparatus/unit or the like, operatively connected to the locking device/structure/component/apparatus/unit and configured to automatically move the locking device/structure/component/apparatus/unit in a release configuration, when the main door is in the closure position, and in a locking configuration, when the main door is not in the closure position.
