A sealing assembly for pressing a garage door horizontally into weather stripping or a door jamb; the sealing assembly having at least one cam-stop assembly, the cam-stop assembly further having at least one cam assembly, at least one linking assembly coupling the cam-stop assembly to the cam assembly, and at least one stop brace. The garage door is sealed when a combination of cam-stop assemblies having topmost cam assembliesthat couple with stop braces and rotate counter-clockwise by exertion of torque to move the garage door forward and downward to form a snug seal with the side of the door jamb and also the bottom floor.

A kit for the assembly of a main door comprises at least two fixed uprights and at least one fixed crossbeam, associable with each other to define a fixed frame that can be attached to an access opening of a compartment, wherein the access opening has relevant reference dimensions; at least two movable uprights and a plurality of panels, associable with the movable uprights to define a movable leaf; a movement device/structure/component/element/unit/apparatus, associable between the movable uprights and the fixed frame; where at least one of the fixed uprights, the fixed crossbeam and the movable uprights is made according to respective predefined standard dimensions, which are bigger than the reference dimensions, and comprises at least one related trimmable portion, provided with at least one graduated reference scale adapted to allow the cutting of the trimmable portion depending on the reference dimensions.

A sectional door may include a plurality of door sections including at least a top section and a bottom section, a hinge assembly operably coupling adjacent door sections to each other to enable the adjacent door sections to pivot relative to each other via the hinge assembly, a roller assembly operably coupling the door sections to a rail assembly to enable the sectional door to transition between an open state and a closed state via the roller assembly carrying the sectional door in the rail assembly, and a switchable viewing pane that transitions between a transparent state and an opaque or translucent state responsive to receipt of a transition signal, the switchable viewing pane being disposed at a portion of one of the door sections.

A stacking screen door has two rails and multiple door panels. Each one of the rails has a groove, a conductive bar, and an elastic assembly. The conductive bar is movably located in the groove. The elastic assembly is connected to the conductive bar and the groove, and is configured to push the conductive bar out of the groove. The door panels selectively move along the two rails and are sequentially connected vertically to each other in the rail. Each one of the door panels has two electric assemblies and multiple display screens. Each one of the display screens is electrically connected to the two electric assemblies. When each one of the door panels moves along the two rails, each one of electric assemblies is respectively connected to the conductive bar. Therefore, power can be supplied to the display screens.
