Description

  The present invention relates to a swivel cover structure for a boarding bridge that can be installed on a vehicle such as an aircraft or a ship from a boarding area such as a terminal building so that passengers can get on and off the vehicle.

  Recently, boarding bridges (boarding bridges) that can be boarded directly in the aircraft from the airport building (terminal building) are used for boarding an aircraft with a high fuselage, for example, at an airport, without using a lap. Yes. The boarding bridge includes a cylindrical boarding bridge main body whose base end is connected to the airport building side, a cab that is connected to the front end of the boarding bridge main body so as to freely rotate in the forward and reverse directions, and is attached to an entrance of an aircraft. (For example, refer to Patent Document 1).

  When the aircraft arrives at a predetermined position near the airport building, the boarding bridge swings at a predetermined angle with respect to the airport building. Moreover, the cab turns to a predetermined angle with respect to the boarding bridge body and is connected so as to cover the boarding port of the aircraft.

  In addition, carpets are usually laid on the boarding bridge main body floor and the cab floor of the boarding bridge. For this reason, the ends of the carpets laid on the boarding bridge body and the cab are fixed by the belt-shaped presser plates so that they are not peeled off at the part of the boarding bridge body and the cab facing each other (turning part). ing. As a result, a step due to each presser plate occurs at the turning portion of the boarding bridge body and the cab.

  Therefore, for example, it is easy for an elderly person or the like who walks on a sliding foot to hit his / her foot, and for a passenger in a wheelchair, there is a problem that the step becomes an obstacle when getting on and off. In particular, for boarding bridges, the height of the boarding gate of an aircraft varies depending on the type of aircraft, with respect to the boarding port portion of an airport building of a certain height. For this reason, the boarding bridge is configured to incline according to the height of the boarding gate of the aircraft, particularly when the crew member pushes the wheelchair in the climbing direction, the problem that the wheelchair is difficult to get over the step becomes significant, It is not desirable in today where barrier-free is promoted.

For the purpose of achieving barrier-free in the boarding bridge, when the boarding bridge main body is formed of a telescopic double cylindrical inner / outer tunnel body, a means for eliminating the step generated at the joint portion of the inner / outer tunnel body is known. (For example, see Patent Document 2).

  A step occurs at the connecting portion between the first tunnel 7a and the second tunnel 7b, but the problem at the time of getting on and off due to such a step is solved by known means as described above, and the description thereof is omitted.

  The cab 9 constitutes a second passage body from a substantially cylindrical cab main body 9a and a substantially rectangular parallelepiped connection portion 9b. The cab main body 9a is configured to be rotatable forward and backward around the vertical axis with respect to the second tunnel 7b by a driving mechanism (not shown) at the end 7e of the second tunnel 7b. The connecting part 9b is for connecting the cab body 9a and the entrance / exit part 13a of the aircraft 13 and is provided integrally with the cab body 9a so that it can expand and contract in the front-rear direction.

  As shown in FIGS. 1 to 3, the rear side of the floor 9c of the cab body 9a (the side facing the end 7e of the second tunnel 7b) has a circular shape centered on the rotation center O. Moreover, the front end side of the floor 7c of the second tunnel is formed in a concave shape along the outer peripheral shape of the cab body 9a. A gap 16 is formed between the convex peripheral surface 9d of the floor 9c of the cab body 9a and the concave peripheral surface 7d of the floor 7c of the second tunnel so as not to slide. The gap 16 is not necessarily provided.

  The end portions (opposing portions) of the second tunnel 7b and the floors 7c and 9c of the cab body 9a are formed in thin portions, and stepped surfaces 7h and 9h having lower surfaces are provided. That is, the upper surface of the end portion 7e of the second tunnel 7b has an inclined surface 7g inclined downward from the floor surface 7f, and a step surface 7h extending horizontally from the inclined surface 7g. A carpet 11 is laid on the floor 7c of the second tunnel 7b. The edge 11a of the carpet 11 is also provided on the inclined surface 7g and the step surface 7h.

  The edge 11a of the carpet 11 is pressed by a band-shaped presser plate 14 so as not to peel off. The presser plate 14 is formed in an arc shape along the concave peripheral surface 7d of the floor 7c, and is fixed to the step surface 7h by a plurality of screws 19.

  An end portion 9e of the floor 9c of the cab body 9a has an inclined surface 9g inclined downward from the floor surface 9f and a step surface 9h extending horizontally from the inclined surface 9g. The height of the step surface 9h is set substantially equal to the step surface 7h on the second tunnel 7b side. The inclined surface 9g and the stepped surface 9h are provided at least in the turning range of the cab body 9a, or are provided over the entire circumference of the cab body 9a.

  A carpet 12 similar to the carpet 11 is laid on the floor 9c of the cab body 9a. The edge 12a of the carpet 12 is also provided on the inclined surface 9g and the step surface 9h. The edge 12a of the carpet 12 is pressed by a band-shaped presser plate 18 so as not to peel off. The holding plate 18 is formed in an arc shape along the outer peripheral shape of the floor 9c of the cab body 9a, and is fixed to at least the step surface 9h of the floor 9c of the cab body 9a by a plurality of screws 24.

  Both pressing plates 14 and 18 are covered with a cover 20. The cover 20 is made of an arc-shaped metal plate along the presser plates 14 and 18, and is provided over the entire length of the passage width H of the tip 7e of the second tunnel 7b, as shown in FIGS. Since the presser plate 18 is provided at least on the step surface 9h, a part thereof is covered with the cover 20. As shown in FIG. 1, the cover 20 is positioned on the upper surface of both of the press plates 14 and 18, and one side (second tunnel 7 b side) 20 a of the cover 20 is fixed to the press plate 14 by the screws 19. The screw 19 fastens the cover 20 and the presser plate 14 together.

  A spacer 21 is interposed between the cover 20 and the pressing plate 14, and the other 20 b side of the cover 20 has a slight gap with respect to the upper surface of the pressing plate 18. An inclined surface 20 c is formed on the end surface on the other 20 b side of the cover 20 so as to approach the carpet 12. An inclined surface 20d that approaches or contacts the carpet 11 is also preferably formed on the end surface of the cover 20 on the one 20a side.

  An anti-slip sheet 31 is fixed on the entire surface of the cover 20 on the upper surface of the cover 20. The upper surface 31a of the anti-slip sheet 31 is set flush with the second tunnel 7b and the floor surfaces 7f and 9f (carpets 11 and 12) of the cab body 9a. For example, the anti-slip sheet 31 is provided with particles such as a grindstone on the upper surface of a base sheet. Specifically, a Safety Walk (registered trademark) manufactured by Sumitomo 3M Limited can be employed. Even if the surface of the anti-slip sheet 31 is wet due to rain or the like, for example, since the surface is rough, it is possible to reliably prevent the slip. The anti-slip sheet 31 is not necessarily provided continuously, and may be provided intermittently as long as the function is not impaired.

  As shown in FIG. 6, the cover 35 is similarly provided also in the turning part between the rotor 5 and the entrance / exit part 3a. In the same figure, the cover 35 is formed of an arc-shaped metal plate material, like the cover 20. One side 35a of the cover 35 is fixed with a screw 43 to a presser plate 41 that presses the edge of the carpet 40 laid on the floor 3b of the entrance / exit 3a. Reference numeral 47 denotes a screw for fixing the presser plate 46 and the carpet 45 to the floor 5 a of the rotor 5.

  Next, the case where the boarding bridge 1 which concerns on the said embodiment is used is demonstrated. First, when attaching the cab 9 of the boarding bridge 1 to the entrance 13a of the aircraft 13 stopped at a predetermined position, an operator who has boarded the cab 9 changes the boarding bridge 1 from the standby position to the boarding / exiting position. Move. The boarding bridge 1 is swung to a predetermined angle by turning the rotor 5. Further, the cab 9 is rotated with respect to the tunnel portion 7 and is mounted on the entrance / exit portion 13 a of the aircraft 13.

  When the cab 9 is rotated, the cover 20 is fixed to the second tunnel portion 7b side, and therefore does not move with respect to the second tunnel portion 7b, but is relatively movable with respect to the cab 9 side. It is. Further, since the other 20b of the cover 20 is slightly separated from the carpet 12 of the cab body 9a, the cover 20 does not come into contact with the carpet 12 and damage the carpet 12 when the cab 9 rotates.

  When passengers get on and off the aircraft 13 using the boarding bridge 1, the cab 9 side, the tunnel portion 7 side, and the cover 20 are flush with each other. The problem due to the step difference between the side and the turning part is solved. Therefore, even if a passenger such as an elderly person walks with a sliding foot, it is safe without being caught by such a stepped portion. Moreover, since the non-slip sheet 31 is fixed to the upper surface of the cover 20, even if the cover 20 gets wet during rainy weather, the passenger will not slip even if the passenger steps on the upper surface of the cover 20.

  In addition, when a passenger in a wheelchair gets on and off, the wheel of the wheelchair rolls on the cover 20, so that it smoothly moves between the tunnel portion 7 and the cab 9 without hindering the rotation of the wheel. be able to.

  For example, in the case of the aircraft 13 having a low entrance / exit part 13a, the boarding bridge 1 is inclined so as to become lower toward the tip side. In particular, when the wheelchair is lowered from the aircraft 13, the boarding bridge 1 is moved while slightly climbing, but the wheelchair wheel rolls on the flat cover 20, which may hinder wheel rotation. In addition, the wheelchair can easily and safely pass through this turning portion, and can move smoothly from the cab 9 to the tunnel portion 7.

  In addition, since the same effect is show | played also in the turning part between the rotor 5 and the entrance / exit part 3a, the description is abbreviate | omitted.

  As described above, according to the present embodiment, passengers, in particular, elderly people and passengers in wheelchairs can get on and off the aircraft 13 easily and safely.

  The present invention is not limited to the embodiment described above. For example, as shown in FIG. 7, the step surface 7h of the second tunnel 7b and the step surface 9h of the cab body 9a are different in height (when the step surface 9h is lower than the step surface 7h). . A belt-shaped sliding member 30 formed from a fluororesin material having a small friction coefficient is fixed to the back surface of the cover 20 on the other 20b side.

  The sliding member 30 has an arc shape along the presser plate 18 so as to slide on the upper surface of the presser plate 18 on the cab body 9a side. The upper surface of the head of the screw 24 for fixing the presser plate 18 is flush with or lower than the upper surface of the presser plate 18. In addition, the sliding member 30 can be provided intermittently in addition to being continuously provided over the entire length of the installation portion 21.

  Thus, by providing the sliding member 30 on the back surface of the cover 20, the cab 9 can be rotated stably and smoothly. Such a sliding member 30 can also be employed in the embodiment shown in FIG.

  Further, as shown in FIG. 8, in addition to the turning portion, the rotor 5 and the tunnel portion 7 may turn relatively, and the cab body 9a and the connection portion 9b may turn relatively. In such a case, in the relationship between the rotor 5 and the tunnel portion 7, the tunnel portion 7 is a first passage body, and the rotor 5 is a second passage body. Then, the cover 35 </ b> A is fixed to the tunnel portion 7.

  Moreover, in the relationship between the cab main body 9a and the connection part 9b, the connection part 9b becomes a 1st channel | path body, and the cab main body 9a becomes a 2nd channel | path body. Then, the cover 20A is fixed to the connection portion 9b.

  Further, the tunnel portion 7 may constitute a first passage body and a second passage body. That is, it is also possible to connect the first tunnel 7a and the second tunnel 7b so as to be able to turn, and to provide a cover at the connecting portion.

  Moreover, although the boarding bridge 1 of the above-described embodiment is an example of an aircraft boarding bridge, the boarding bridge 1 may be constructed between a ship and a wharf.
