Aircraft passenger boarding bridge system

A cab for serving as a portal between an aircraft passenger boarding bridge walkway and an aircraft exterior cabin door and for aligning the walkway to the cabin door to permit passengers to board the aircraft from the walkway, comprising:

• (a) a frame to which are attached vertical side walls, a ceiling panel and a floor to form a passageway open at its opposite ends, said passageway sized to permit a person to pass there through;
• said floor comprising a first, second and third panel each having a leading edge positioned at one of the open ends of said passageway that will be positioned toward the aircraft, and each leading edge aligned with one another in a first operating position, said second panel being positioned intermediate said first and third panels;
• and
• (b) a power source operatively connected to said first, second and third panel to enable each panel to separately or together to be retracted to a second operating position whereby said leading edge of each of the retracted panels extends a lesser distance toward the aircraft than at said first operating position, said power source further operatively connected to said second panel to enable said second panel to extend to a third operating position whereby said leading edge of said second panel extends a greater distance toward the aircraft than at said first operating position.

A cab for serving as a portal between an aircraft passenger boarding bridge walkway and an aircraft exterior cabin door to permit passengers to board the aircraft from the walkway, wherein the walkway having one end attached to a passenger terminal building and its opposite end extending out from the building, comprising a frame to which are attached vertical side walls, a ceiling panel and a floor to form a passageway open at its opposite ends, said passageway sized to permit a person to pass there through;

• wherein a first section of said frame forming at least in part one of said open ends of said passageway being attachable to the opposite end of the walkway permitting said frame to move side-to-side relative to the opposite end of the walkway;
• wherein said floor comprises a first, second and third panel each having a leading edge positioned at one of the open ends of said passageway that will be positioned toward the aircraft, and each leading edge aligned with one another in a first operating position;
• said second panel being positioned intermediate said first and third panels;
• and a power source operatively connected to said first, second and third panel to enable each panel to separately or together to be retracted to a second operating position whereby said leading edge of each of the retracted panels extends a greater distance from the aircraft than at said first operating position, said power source further operatively connected to said second panel to enable said second panel to extend to a third operating position whereby said leading edge of said second panel extends a lesser distance from the aircraft than at said first operating position.

A cab for serving as a portal between aircraft passenger boarding bridge walkway and an aircraft to permit passengers to board the aircraft, comprising:

• (a) a frame to which are attached vertical side walls, a ceiling panel and a floor to form a passageway open at its opposite ends, said passageway sized to permit a person to pass there through;
• (b) a means operatively attachable to said frame to permit said frame to shift laterally in either direction from its center;
• and
• (c) a power source operatively connected to said means to cause when activated said means to move said frame laterally in relationship to said door.

An aircraft passenger boarding bridge comprising:

• (a) a walkway having one end operatively connectable to an airport passenger terminal building to permit passengers to enter or exit said walkway, and having its opposite end extending out from said building;
• and
• (b) a cab comprising a frame to which are attached vertical side walls, a ceiling panel and a floor to form a passageway open at the opposite ends, said passageway sized to permit a person to pass there through;
• said cab operatively connected to said opposite end of said walkway to permit said cab to move parallel to said opposite end of said walkway;
• and
• (c) a power source containing assembly operably connected to either said frame or said walkway to cause said frame to move parallel to said opposite end of said walkway.

An aircraft passenger boarding bridge comprising:

• (a) a walkway having one end operatively connectable to an airport passenger terminal building to permit passengers to enter or exit said walkway, and having its opposite end extending out from said building;
• (b) an apron affixed to said opposite end of said walkway;
• (c) a cab comprising a frame to which are attached vertical side walls, a ceiling panel and a floor to form a passageway open at its opposite ends, said passageway sized to permit a person to pass there through;
• (d) a means fixed to said apron and operatively connected to said frame to cause said frame to shift laterally in either direction from the center;
• and
• (e) a power source operatively connected to said means to activate said means to cause said frame to move.
