Definitions

  • the present invention relates generally to passenger loading bridges and more particularly to a flexible over-the-wing passenger loading bridge for servicing a rear doorway of a nose-in parked aircraft.
  • an apron drive bridge in present day use comprises a plurality of adjustable modules, including: a rotunda, a telescopic tunnel, a bubble section, a cab, and elevating columns with wheel carriage.
  • Manual, semi-automated and automated bridge alignment systems are known for adjusting the position of the passenger loading bridge relative to an aircraft, for instance to compensate for different sized aircraft and to compensate for imprecise parking of an aircraft at an airport terminal, etc.
  • other types of bridges are known in the art, such as for example nose loaders, radial bridges and pedestal bridges.
  • aircraft aisle design is such that passenger flow rate along aircraft aisles is a limiting factor, which slows down the entire deplaning operation. That is, the aircraft doorways and most passenger loading devices are capable of handling substantially higher passenger flow rates than are the aircraft aisles. Of course, similar delays are also encountered during the boarding, or enplaning, operation. This limitation is of serious concern in a marketplace where airlines consistently struggle to shorten the turn-around time of their aircraft in order to boost operating efficiency, lower operating costs and thereby offer lower fares to their customers.
  • Some types of aircraft include a rear door through which passengers can enter and leave the aircraft by means of steps that are lowered from the aircraft onto the apron or tarmac, or by means of mobile steps that are connected to the door by ground personnel.
  • One drawback with this approach is that it is necessary for passengers ' to walk onto the apron and then walk up steps into the passenger bridge.
  • accessibility may be a concern for some passengers, such as for instance a passenger using a wheelchair.
  • Parallel parking offers the advantage that the aircraft arrives and departs from its parked position under its own power, and thus requires no tow tractor in its turnaround cycle. Further, the orientation of the aircraft with respect to the terminal facade in parallel parking facilitates access to aircraft doorways either forward of or aft of the wing with known ramp supported loading bridges.
  • parallel parking presents one very significant disadvantage. Parallel parking necessitates certain aircraft turning and maneuvering room, and therefore this technique requires greater terminal facade length than does the nose-in technique.
  • U.S. Patent 3,538,529 issued to Breier on November 10, 1970 discloses an overhead supported aircraft loading bridge, including a slightly arched telescoping tunnel section, which may be cantilevered over the wing of an aircraft for servicing a rear doorway thereof.
  • the entire telescoping tunnel section is pivotally connected to a static structure, thereby providing limited freedom of vertical motion for clearing the wing and mating to the rear doorway of the aircraft. It is a disadvantage of this system that the telescoping tunnel section is pivotally connected at a point that is directly above a support leg of the static structure.
  • a wing of a nose-in parked aircraft cannot be positioned directly below the pivotal connection point, but must instead stop at some distance away from the connection point, making it impossible to provide a uniformly sloping floor surface between the connection point and the rear doorway of the aircraft.
  • the angle of the telescoping tunnel section is fixed, such that the slope of the telescoping tunnel section floor members is other than adjustable. Accordingly, depending upon the size of an aircraft being serviced, it is possible that a slope exceeding 1:12 will result when the bridgehead is aligned with a rear doorway of the aircraft. As will be obvious to one of skill in the art, a slope that exceeds 1:12 is unacceptable in a boarding structure.
  • DE 10046010 discloses a similar system in which a non-arched telescoping tunnel section is pivotally connected to an outboard end of a radial bridge. It is a disadvantage of the system disclosed in DE 10046010 that the radial bridge is supported at its outboard end, such that the telescoping tunnel section is pivotally connected to the radial bridge at a point that is directly above the wheel carriage structure and height adjustable frame. Accordingly, a wing of a nose-in parked aircraft cannot be positioned directly below the pivotal connection point, but must instead stop at some distance away from the connection point. This system suffers from the same disadvantages that were discussed supra with reference to U.S. Patent 3,538,529.
  • U.S. Patent 3,722,017 issued to Gacs et al. on March 27, 1973 discloses an over- the-wing aircraft loading bridge having a main passageway member pivotally supported at the terminal building end on a track mounted rack propelled carriage.
  • the main passageway member is elevatable and depressable so that its outer end portion, slightly arched, may extend over the wing of an aircraft.
  • the main passageway mounts a lateral passageway including an operator's cab, which is for being mated to a rear doorway of the aircraft.
  • the lateral passageway appears to serve as a bridge between the rear doorway and the main passageway element, which passageway lacks sufficient freedom of vertical movement to engage the rear doorway directly.
  • Kubatzki in WO 0009395 discloses an over the wing bridge including at least one horizontally pivotal extension arm, which extension arm is mounted on a static structure.
  • An access tunnel including a device on the end thereof for docking to the airplane, is coupled to the extension arm.
  • the static structure and the extension arm appear to severely limit the ability of the bridge to pivot both horizontally and vertically. Accordingly, it is likely that the wing of the aircraft must be driven underneath the access tunnel, which many airline pilots strongly object to doing.
  • Worpenberg in WO 0055040 discloses an over-the-wing bridge including a telescopic tunnel section that can be swiveled over the wing of an aircraft and which is supported by an extension arm that is fixedly or moveably mounted on a frame.
  • the telescopic tunnel section is straight, and as such the inboard end of the tunnel section must be at a higher level relative to the outboard end of the tunnel section in order to engage the rear doorway of an aircraft whilst maintaining acceptable clearance above the aircraft wing. This may result in the upward slope of the telescopic tunnel section toward the terminal being unacceptable steep.
  • the bridge includes a passageway extending from a rotunda and which can be cantilevered over the wing of an aircraft to mate a cabin at the outboard end of the passageway to a rear doorway of the aircraft.
  • the passageway is supported at a variable height by an adjustable wheel carriage in front of the wing and is permanently arched at a predetermined angle. Accordingly, vertical swinging motion occurs only at a point where the bridge is mounted to a fixed structure, such as one of a rotunda and a terminal building. It is a disadvantage that for certain combinations of fixed structure access height and aircraft rear doorway position, servicing the rear doorway is awkward or impossible due to the limited vertical motion of the cabin end.
  • a passenger loading bridge for servicing an aircraft having a rear doorway aft of or over a wing
  • the passenger loading bridge comprising: a first passageway member having a length and including an inboard end and an outboard end, the inboard end for being pivotally mounted to a support and the outboard end for being positioned in a direction toward an aircraft; a telescopic passageway member having an inboard end and an outboard end and including at least two passageway elements, one that is telescopically received within the other such that a distance between the inboard end and the outboard end of the telescopic passageway member is variable, the telescopic passageway member for being supported in a cantilever like fashion such that, in use, the telescopic passageway member is extensible over a wing of an aircraft; a flexible connection disposed between the first passageway member and the telescopic passageway member for pivotally coupling the outboard end of the first passageway member and the inboard
  • a method of automatically aligning a passenger loading bridge to an aircraft having a rear doorway aft of or over a wing comprising the steps of: stopping an aircraft adjacent to the passenger loading bridge; enabling an automated bridge control system of the passenger loading bridge; providing a type of the aircraft; automatically moving the passenger loading bridge such that a highest point along a wing of the aircraft is disposed approximately below a flexible connection of the passenger loading bridge and to engage a rear doorway of the aircraft; and, adjusting an angle between two tunnel sections of the passenger loading bridge, the two tunnel sections being disposed one each on opposite sides of the flexible connection, such that a slope of a floor member of each tunnel section is within a predetermined range of threshold values.

  • the flexible connection includes a floor plate (not shown) to provide a level surface over which passengers move through the bridge. The flexible connection permits vertical swinging of the telescopic tunnel section 21 about a horizontal axis passing through the floor connector 11.
  • the loading bridge is for being cantilevered and extended over the wing of the nose-in parked aircraft 10 to service the rear doorway 9. Accordingly, the inboard end of the first passageway member 2 is pivotally anchored to the stationary rotunda 4, preferably being at more or less the same elevation as the doorways in the aircraft 10.
  • the first passageway member 2 is supported near the outboard end thereof by a wheel carriage including a height adjustable support post 19 and drive wheels 3.

Abstract

L'invention concerne un nouveau dispositif permettant le passage de passagers entre le bâtiment d'un terminal d'aéroport et la porte d'un avion située à l'arrière de l'aile de celui-ci. L'appareil présenté comprend un couloir (108) ancré, de façon à pouvoir pivoter, à un des bâtiments de terminal, ainsi qu'une passerelle d'embarquement de passagers destinée à la porte avant dudit avion. L'appareil comprend un couloir télescopique (110) qui est monté, de façon à pouvoir pivoter, sur le couloir (108), par l'intermédiaire d'un raccord flexible (116). Pendant son utilisation, l'appareil est en porte-à-faux au-dessus de l'aile de l'avion, le raccord flexible (116) étant placé sensiblement au-dessus du point le plus élevé de l'aile de l'avion, le long de la surface supérieure de.celle-ci. Le raccord flexible (116) permet à une cabine (106) portée par l'extrémité extérieure du couloir télescopique (110) de s'adapter à la porte arrière de l'avion, créant ainsi un passage ouvert entre ladite porte arrière et le bâtiment de terminal, passage par lequel les passagers peuvent passer. Le positionnement du raccord flexible (116) au-dessus du point le plus élevé de l'aile réduit approximativement au minimum l'inclinaison de chaque surface de plancher de couloir.
