DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(13) In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part thereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.

(14) As used in this specification and the appended claims, the singular forms a, an, and the include plural referents unless the content clearly dictates otherwise. As used in this specification and the appended claims, the term or is generally employed in its sense including and/or unless the context clearly dictates otherwise.

(15) In certain embodiments, the current invention is an aerobridge and dual method of operation thereof that significantly reduces the boarding and deplaning times, which in turn, reduces turnaround time (time between routes) of an aircraft vehicle at a terminal gate.

(16) Structure

(17) In certain embodiments, the current invention is an aerobridge that includes a vertically- and horizontally-adjustable cantilevered, open-sided (e.g., U-shaped with one open side) apparatus including a plurality of passageways that have one end attached to a cab and an opposite end that is retractable and can extend over the aircraft's wing root to access doors or hatches above the wing. The apparatus further includes horizontally-extendible ramps that couple passageways together and mate with the aircraft body, providing total protection of the aircraft's wing root. Along the length of an aircraft, the aerobridge provides simultaneous access to all doors (e.g., before the wing roots, over-the-wing roots, and aft the wing roots) for passengers embarking or disembarking the aircraft. The passageways are extendible using any suitable mechanism, for example telescopic extension and retraction, accordion-like extension and retraction, etc. In this way, the aerobridge provides horizontal adjustability based not only on the length of an aircraft but also positioning of particular entry and exit doorways.

(18) In certain embodiments, the current aerobridge also provides vertical adjustability based on the heights of entry and exit doorways on a particular aircraft. Whereas many conventional PBBs are hindered by stationary support columns, the current aerobridge includes a retractable support system located at the distal end of the passageways. This support system deploys when the aerobridge is in service and retracts when the aerobridge has completed servicing the aircraft. Further, this support system is height adjustable depending on heights of the aircraft doorways.

(19) In certain embodiments, the current aerobridge includes two spaced supports, including the retractable support system described previously. Having the two spaced supports provides a balance of weight distribution of the passageways. The first of these two supports is a drive column located in underlying relation to the largest, outermost passageway to support the weight of cab and the passageways. The second support is a retractable, fail-safe, support system located in underlying relation to the smallest, innermost passageway at its distal end. This support system can be deployed when the aerobridge is in its fully retracted position or when the aerobridge is in its fully extended position or any position therebetween (i.e., when the aerobridge is used to service doors located distal to the wing root), thus eliminating the risk of a bridge collapse that can result in a fire at the terminal gate.

(20) With both horizontal and vertical adjustability, the current aerobridge offers a universally-applicable system that can be implemented on different aircrafts that having varying positions of doorways along their bodies. The aerobridge provides simultaneous access to multiple doors at several spaced locations along the side of the aircraft.

(21) Optionally, certain embodiments of the instant aerobridge may include a plurality of proximity sensors disposed along the passageways and/or along the open side(s) of the passageways. These proximity sensors sense nearby structures and either provide notification to the operator or itself communicates to the aerobridge's control panel to maintain a safe distance from the nearby structures. This eliminates any chance of causing damage to the body of the aircraft, permits safe mating with the aircraft, and maintains a safe vertical distance between the aerobridge and the top of the wing of the aircraft.

(22) Additionally, certain embodiments of the instant aerobridge may include one or more weight/load sensors, such as a load cell, positioned underneath the bridge/passageways to detect a weight or other downward force being placed on the aerobridge. If the weight or downward force exceeds a particular threshold, the sensor can transmit a signal to an operator or other authorized individual to notify him/her that there is excessive weight being placed on the bridge and additional precautions may need to take place to prevent the aerobridge or any corresponding passageways from collapsing. Alternatively or in addition, if the weight or downward force exceeds a particular threshold, the sensor can transmit a signal to the support system of the aerobridge such that the support system automatically reinforces its support mechanism to prevent collapse of the aerobridge.

(23) This and other optional, suitable safety mechanisms are contemplated by the instant invention as well.

(24) Using the disclosed structure, in certain instances, the current aerobridge is configured to be coupled with existing/currently installed PBBs, so that airports and airlines would not have to replace the existing PBB. Rather, the current aerobridge, specifically the passageways and ramps and support system, can be used as an add-on that is coupled to the cab of the existing PBB. In other instances, the current aerobridge exists as a full PBB with components that connect the terminal from the cab and components that extend over the wing of the plane.

(25) Example

(26) In an embodiment, shown in FIGS. 2A-2E, the current invention is an aerobridge, generally denoted by the reference numeral 10. Aerobridge 10 includes cab rotunda 12, cab 14, and an extendible bridge formed of a plurality of passageways. Cab rotunda 12 and cab 14 are configured to connect to an airport's existing equipment and jet bridge, leading to the airport's terminal gate, as indicated by the arrow in FIG. 2A.

(27) The extendible bridge comprises first passageway 16 (proximal-most passageway), horizontally extendible ramp 18, second passageway 20, third passageway 22 (distal-most passageway), and distal housing 24. Aerobridge 10 further includes a support system, which comprises retractable end support 26 and drive support column 28. Housing 24 is configured to substantially enclose retractable end support 26.

(28) Drive support column 28 includes a plurality of support mechanisms (wheels, support frame, support legs, cross supports, etc.), where a support frame may be vertically extendible/adjustable (see arrows in FIGS. 2C and 2E) based on height of the aircraft vehicle. The support frame may be extendible/adjustable in any suitable manner, for example hydraulically.

(29) Aerobridge 10 can have outwardly facing wall 30 formed of any suitable material, such as steel or glass.

(30) As noted previously, the bridge is extendible in any suitable manner, for example by telescopically-received passageways or by accordion-like extensions of passageways. Herein, for illustrative purposes, the mechanism of telescopic extension and retraction will be described. In this case, still referring to FIGS. 2A-2E, first passageway 16 telescopically receives horizontally extendible ramp 18; horizontally extendible ramp 18 telescopically receives second passageway 20; second passageway 20 telescopically receives third passageway 22; and housing 24 is disposed at the distal end of third passageway 22 and receives retractable end support 26 (see arrows in FIG. 2C) when the bridge is retracted into first passageway 16. Alternatively, ramp 18 itself can have walls formed of bellows, such that ramp 18 undergoes accordion-like extension and retraction, where passageways 16/20/22 still retain their telescopic assembly.

(31) Generally, first passageway 16, second passageway 20, and third passageway 22 can each include an access point (not shown) into or out of the aircraft vehicle, such that passengers can enter or exit any of these access points. This access point can be an entirely open side along the extendible bridge, as can be seen by the broken lines in FIG. 2E, where the top and bottom sides of the bridge mate with the side of aircraft vehicle 11. As shown, when aerobridge 10 is in use, the open side of the bridge is closed off by the wall of aircraft vehicle 11 itself.

(32) First passageway 16, horizontally extendible ramp 18, second passageway 20, and third passageway 22 are horizontally adjustable in order to line up with the doors provided on aircraft vehicle 11. Further, if, for example, aircraft vehicle 11 has only two (2) doors, third passageway 22 may remain retracted or telescopically received within second passageway 20 with the access points (i.e., open sides) of second passageway 20 and third passageway 22 aligned, so that passengers can continue to enter or exit aircraft vehicle 11 without hindrance.

(33) First passageway 16, horizontally extendible ramp 18, second passageway 20, and third passageway 22 can all be U-shaped, with the U-shape opening horizontally toward aircraft vehicle 11, as indicated by the broken lines in FIG. 2E. In this scenario, the top and bottom edges of the U-shape press against the sidewall of aircraft vehicle 11, such that when the bridge is extended along aircraft vehicle 11, the sidewall of aircraft vehicle 11 essentially becomes the inner wall of the bridge along first passageway 16, horizontally extendible ramp 18, second passageway 20, and third passageway 22. Here, the bridge can still be considered to include a plurality of access points, although the access points are in the form of an elongate opening of the U-shape, where passengers can still access the doors of aircraft vehicle 11.

(34) As can be understood, aerobridge 10 has a fully retracted position, a fully extended position, and a plurality of positions therebetween depending on the length of bridge that is needed for aircraft vehicle 11. In the fully retracted position, ramp 18, second passageway 20, and third passageway 22 are retracted into (i.e., telescopically received by) first passageway 16. Further, in this fully retracted position, end support 26 is retracted into housing 24, and optionally, the support frame of drive support column 28 is vertically retracted in underlying relation to first passageway 16. It is contemplated herein that the support frame of drive support column 28 may also not be fully vertically retracted between uses, as most aircrafts may have heights that require a minimum level of extension of the support frame of drive support column 28. Maintaining a certain extension of the support frame of drive support column 28 may reduce the turnaround time of aircraft vehicle 11. Aerobridge 10 can be considered to be in its retracted position even if the support frame of drive support column 28 is not fully vertically retracted.

(35) Similarly, an operator may wish to maintain a length of the bridge beyond full retraction into first passageway 16 if the aircrafts being serviced generally have similar door positions. This might also reduce turnaround time of aircraft vehicle 11, due to not having to extend the bridge from first passageway 16 every time. Aerobridge 10 can be considered to be in its retracted position even if ramp 18, second passageway 20, and/or third passageway 22 are not fully retracted into first passageway 16.

(36) Aerobridge 10 also has a fully expanded position where ramp 18, second passageway 20, and third passageway 22 are expanded out of first passageway 16 along the length of aircraft vehicle 11. Additionally, end support 26 is expanded out of housing 24 and contacting the ground, and drive support column 28 is extended/elevated to the appropriate height. This fully expanded position can be seen in FIGS. 2A-2D.

(37) As noted, aerobridge 10 also has a plurality of positions between the fully retracted position and the fully extended position depending on the length of the bridge needed. For example, if an operator requires aerobridge 10 to service two (2) doors that are located proximal to the wing root of aircraft vehicle 11, then the bridge can be extended as needed with the open sides aligned to provide access to the doors. However, because the doors are positioned proximal to the wing root of aircraft vehicle 11, it is likely that end support 26 does not need to be expanded out of housing 24 to contact the ground, as additional support for the bridge beyond drive support column 28 may not be required, since the bridge is not extended past the wing root of aircraft vehicle 11. Typically, when entry/exit doorways are located after the wing root, the bridge can extend beyond the wing root and additional support, specifically end support 26, is expanded to support the distal portions of the extended bridge.

(38) It can be understood that horizontally extendible ramp 18 can be positioned anywhere along the bridge, for example between first passageway 16 and second passageway 20 (see FIG. 2A), on a proximal side of first passageway 16 (see FIG. 2D), between second passageway 20 and third passageway 22, among other configurations. The positioning of ramp 18 is determined by the type of aircraft vehicle 11 and disposition of its doors. In other words, ramp 18 can be positioned according to the needs of the operator.

(39) Dual Method of Operation

(40) As discussed previously, there are two (2) primary methods of parking aircrafts at a terminal gate: nosed-in parking and parallel parking. Many, if not all, conventional PBBs are incapable of complying with both parking methods, whereas certain embodiments of the current invention are capable of being used during either parking method. The instant aerobridge is capable of docking/mating with an aircraft using one of two methods, namely the shoot-out method (FIGS. 3A-3B) or the swing method (FIGS. 4A-4B). The dual method of operation of the instant aerobridge is advantageous over conventional systems that mate with and detach from aircrafts using a single method, and its benefit can be demonstrated during application in airports or terminal gates where space is limited. In other words, certain embodiments of the current invention can be used to serve an aircraft parked either nosed-in or parallel at the terminal gate, which is particularly desirable for airports where ramp space is limited.

(41) During extension in the shoot-out method (FIG. 3A), aircraft vehicle 11 parks at the terminal gate, where information is retrieved or automatically received pertaining the type, height, etc. of aircraft 11. Cab 14 of aerobridge 10 is moved and mated to aircraft vehicle 11. End support 26 can be retracted into or remain retracted in housing 24 if the distal stop position of the bridge is above the wing roots of aircraft vehicle 11 or is proximal to the wing roots of aircraft vehicle 11. Passageways 20, 22 (and optionally ramp 18) are extended telescopically to the distal stop location and mated with aircraft vehicle 11. End support 26 can then be extended out of housing 24 if needed, typically when the distal stop position of the bridge is distal to the wing roots of aircraft vehicle 11.

(42) During retraction in the shoot-out method (FIG. 3B), end support 26 is retracted into housing 24 if its position is distal to the wing roots of aircraft vehicle 11. Passageways 20, 22 (and optionally ramp 18) are retracted telescopically and detached from aircraft vehicle 11. Cab 14 of aerobridge 10 can then be detached from aircraft vehicle 11, and aerobridge 10 can be moved away from aircraft vehicle 11.

(43) In the case when aircraft vehicle 11 includes wingtips and is to be serviced, aerobridge 10 can utilize the shoot-out method to mate with vehicle 11, thus avoiding the vertical, upward height created by the wingtips.

(44) During extension in the swing method (FIG. 4A), aircraft vehicle 11 parks at the terminal gate, where information is retrieved or automatically received pertaining type, height, etc. of aircraft vehicle 11. End support 26 can be retracted into or remain retracted in housing 24 if the distal stop position of the bridge is above the wing roots of aircraft vehicle 11 or is proximal to the wing roots of aircraft vehicle 11. Alternatively, end support 26 can be extended out of housing 24 if the distal stop position of the bridge is distal to the wing roots of aircraft vehicle 11. Passageways 20, 22 (and optionally ramp 18) are extended telescopically to align with the assigned distal stop position of aircraft vehicle 11 through the predetermined swing angle. Cab 14 of aerobridge 10 and passageways 20, 22, 22 (and optional ramp 18) move toward aircraft vehicle via the predetermined swing angle and then are mated to aircraft vehicle 11.

(45) During retraction in the swing method (FIG. 4B), end support 26 is retracted into housing 24 if its position is distal to the wing roots of aircraft vehicle 11. Passageways 20, 22 (and optionally ramp 18) are detached from aircraft vehicle 11 and retracted telescopically. Cab 14 of aerobridge 10 can then be detached from aircraft vehicle 11, and aerobridge 10 can be moved away from aircraft vehicle 11.

(46) It is contemplated herein that the current aerobridge can be operated manually or autonomously in any suitable manner. Generally, the automated ability of the instant aerobridge eliminates the need for additional bridge operators and gate control staff needed to operate multiple jetways, thereby increasing profitability, time efficiency and customer satisfaction. These two exemplary methods (shoot-out and swing methods) are typically present when the aerobridge is operated autonomously. For example, when aerobridge 10 is completely automated, when the characteristics of aircraft vehicle 11 are known/received and the shoot-out method or swing method is selected, aerobridge 10 is automatically activated and extends/retracts according to the methodology selected.

(47) Glossary of Claim Terms

(48) Distal stop position: This term is used herein to refer to a location or distance at which the distal end of the bridge should cease continued distal extension. This location/distance is based on the aircraft vehicle being serviced and in particular the positioning of its entry/exit doors.

(49) Distal: This term is used herein to refer to a relative position further from the cab of the aerobridge or nose of the aircraft vehicle, and closer to the tail of the aircraft vehicle.

(50) Open inner side: This term is used herein to refer to the opening in a sideways U-shaped structure. This opening is closed off by the wall of the aircraft vehicle when the bridge is mated to the aircraft vehicle.

(51) Predetermined swing angle: This term is used herein to refer to the angle at which the aerobridge, including passageways, can move, relative to the length of the aircraft vehicle, in order to mate with the aircraft vehicle. This swing angle is based on the aircraft vehicle being serviced.
