特開２００５−３４９９９３号公報JP 2005-349993 A

図１１に示した乗客乗降用車両１００では、フロア被覆部１０６の後壁１０７と階段被覆部１０５とは別体であり、階段被覆部１０５は傾斜しており、その前端部が、フロア被覆部１０６の後壁１０７に接続されている。   In the passenger boarding / alighting vehicle 100 shown in FIG. 11, the rear wall 107 of the floor covering portion 106 and the staircase covering portion 105 are separate bodies, the staircase covering portion 105 is inclined, and the front end portion thereof is the floor covering portion. 106 is connected to the rear wall 107.

しかしながら、図１１に示した乗客乗降用車両１００では、後壁１０７と階段被覆部１０５の前端部との接続部１０８を覆うものがない。このため、経年によって、接続部１０８から雨水が被覆部の内部に侵入し易い。また、降雪が接続部１０８やその周辺に積雪すると、その重みにより接続部１０８の隙間が大きくなり、水分が被覆部の内部に侵入し易い状態になる。   However, in the passenger boarding / alighting vehicle 100 shown in FIG. 11, there is nothing that covers the connection portion 108 between the rear wall 107 and the front end portion of the staircase covering portion 105. For this reason, rainwater tends to enter the inside of the covering portion from the connection portion 108 over time. Further, when snow falls on the connecting portion 108 and its periphery, the gap between the connecting portions 108 becomes large due to the weight, and moisture easily enters the inside of the covering portion.

そこで本発明は、フロア被覆部の後壁と階段被覆部の前端部との接続部から、被覆部の内部に水分が侵入するのを抑制し得る乗客乗降用車両の提供を目的とする。   Then, this invention aims at provision of the passenger boarding / alighting vehicle which can suppress that a water | moisture content penetrate | invades into the inside of a coating | coated part from the connection part of the rear wall of a floor coating | coated part, and the front-end part of a staircase coating | coated part.

本発明の乗客乗降用車両は、台車と、該台車に支持されるタラップとを備え、該タラップは、機体の乗降口に合わされるフロア部と、該フロア部の後方に配置されてフロア部に向けて上傾斜するスロープと、前記フロア部およびスロープを覆う被覆部とを備え、該被覆部は、前記フロア部を覆う第一被覆部と、前記スロープに倣って上傾斜してスロープを覆う第二被覆部とを備え、前記第一被覆部はその後方に配置された後壁を備え、該後壁はその下部ほど前方へ傾斜され、第二被覆部の前端部の上部が前記後壁の上端縁に対して下方に配置された状態で、第二被覆部の前端部が後壁に接続されていることを特徴としている。   A passenger boarding / exiting vehicle according to the present invention includes a carriage and a trap supported by the carriage, and the trap is disposed on a floor portion that is disposed at the rear of the floor portion and that is disposed at a floor portion of the aircraft. And a covering portion covering the floor portion and the slope, and the covering portion includes a first covering portion covering the floor portion, and a first covering portion covering the slope by inclining upward along the slope. The first covering portion includes a rear wall disposed behind the first covering portion, the rear wall is inclined forward toward the lower portion thereof, and an upper portion of a front end portion of the second covering portion is disposed on the rear wall. The front end portion of the second covering portion is connected to the rear wall in a state of being disposed below the upper end edge.

上記構成のように、後壁がその下部ほど前方へ傾斜され、第二被覆部の前端部の上部が後壁の上端縁に対して下方に配置された状態で、第二被覆部が後壁に接続されていれば、接続部に対して、第一被覆部の上部が上側で且つ後方へ延長されているから、その延長部分によって、接続部から水分が侵入するのを抑えられる。   As in the above configuration, the rear wall is inclined forward toward the lower part, and the upper part of the front end of the second covering part is disposed below the upper edge of the rear wall, and the second covering part is the rear wall. Since the upper part of the 1st coating | coated part is extended upwards and back with respect to the connection part, it can suppress that a water | moisture content penetrate | invades from a connection part by the extension part.

本発明の乗客乗降用車両では、第一被覆部の後壁がその下部ほど前方へ傾斜され、第二被覆部の前端部の上部が後壁の上端縁に対して下方にあって、第二被覆部が後壁に接続されていることにより、後壁の上部が接続部に対して上側で後方へ延長されるよう突出しているから、その突出部によって接続部に雨水が直接あたる量や積雪を抑えられ、被覆部の内部への水の侵入を抑制できる。   In the passenger boarding / alighting vehicle according to the present invention, the rear wall of the first covering portion is inclined forward toward the lower portion, the upper portion of the front end portion of the second covering portion is below the upper end edge of the rear wall, Since the upper part of the rear wall protrudes upward and backward with respect to the connection part due to the connection of the covering part to the rear wall, the amount of rainwater directly hitting the connection part by the protrusion and the amount of snow And water can be prevented from entering the inside of the covering portion.

そして、上段側用被覆部２２の側壁２８の上下方向高さに比べて、フロア部用被覆部２０の側壁２３および後壁２５の上下方向高さが高く設定されていることで、上段側用被覆部２２の前端部２２ａは、突出部２０Ａの上端部２０ａに比べて下方に位置し、且つ前方に位置している。   The height in the vertical direction of the side wall 23 and the rear wall 25 of the floor covering portion 20 is set to be higher than the height in the vertical direction of the side wall 28 of the upper covering portion 22. The front end portion 22a of the covering portion 22 is positioned below and in front of the upper end portion 20a of the protruding portion 20A.

上記構成において、オペレータは運転操作室１Ａに搭乗し、フロア部１１が航空機３の機体３０の乗降口３００に接近するよう、車両１を移動させる。そして、オペレータは、必要に応じて前記階段部用伸縮装置を操作して、階段部１０をその傾斜方向に伸縮させ、フロア部１１を航空機３の機体３０の乗降口３００に合わせるよう、車両１を機体３０に近づける。   In the above configuration, the operator gets into the driving operation room 1 </ b> A and moves the vehicle 1 so that the floor portion 11 approaches the entrance / exit 300 of the fuselage 30 of the aircraft 3. Then, the operator operates the staircase extension / contraction device as necessary to extend / contract the staircase portion 10 in the inclination direction, and to adjust the floor portion 11 to the entrance / exit 300 of the fuselage 30 of the aircraft 3. Is brought closer to the fuselage 30.

ところで、本実施形態に係る車両１の被覆部１３は、フロア部用被覆部２０の天壁２４と後壁２５とで形成された突出部２０Ａを備える。突出部２０Ａは、上段側用被覆部２２の前端部２２ａの上方にあって、前端部２２ａに対してその後方へ突出するよう形成されている。換言すれば、上段側用被覆部２２の前端部２２ａは、突出部２０Ａの上端部２０ａに比べて下方且つ前方に位置している。   By the way, the covering portion 13 of the vehicle 1 according to the present embodiment includes a protruding portion 20 </ b> A formed by the top wall 24 and the rear wall 25 of the floor covering portion 20. The protruding portion 20A is located above the front end portion 22a of the upper stage side covering portion 22, and is formed to protrude rearward with respect to the front end portion 22a. In other words, the front end portion 22a of the upper stage side covering portion 22 is positioned lower and forward than the upper end portion 20a of the protruding portion 20A.

このため、フロア部用被覆部２０の後壁２５と上段側用被覆部２２の前端部２２ａとの接続部、すなわち外側凹部２５ａと上段側用被覆部２２の前端部２２ａとの嵌合部に、降雨が直接当るのを回避することが可能である。したがって、フロア部用被覆部２０の後壁２５と上段側用被覆部２２とが別体とされたうえで接続されていたとしても、前記接続部から被覆部１３の内部へ水が侵入するのを抑制できる。   For this reason, the connecting portion between the rear wall 25 of the floor covering portion 20 and the front end portion 22a of the upper covering portion 22, that is, the fitting portion between the outer recessed portion 25a and the front end portion 22a of the upper covering portion 22 is used. It is possible to avoid hitting the rain directly. Therefore, even if the rear wall 25 of the floor covering portion 20 and the upper covering portion 22 are separated and connected, water enters the inside of the covering portion 13 from the connecting portion. Can be suppressed.

また、突出部２０Ａは、前記接続部に対する庇の機能を有する。このため、降雨が直接当るのを回避可能であるとともに、仮に被覆部１３に積雪しても、被覆部１３における接続部近傍には、積雪しにくい。このため、積雪の重さによって接続部に隙間が生じたとしても、すなわち外側凹部２５ａと上段側用被覆部２２の前端部２２ａとの間に隙間が生じたとしても、接続部から被覆部１３の内部へ水が侵入するのを抑制できる。   Further, the protruding portion 20A has a function of a hook with respect to the connecting portion. For this reason, it is possible to avoid the direct hitting of rain, and even if snow is deposited on the covering portion 13, it is difficult to accumulate snow near the connection portion in the covering portion 13. For this reason, even if a gap is generated in the connection portion due to the weight of snow, that is, even if a gap is generated between the outer concave portion 25a and the front end portion 22a of the upper-side cover portion 22, the connection portion to the cover portion 13 is formed. It is possible to suppress water from entering the inside.

本実施形態では、フロア部用被覆部２０の前後方向に直交する断面は、上段側用被覆部２２において、その長手方向に直交する断面に比べて、大きく設定されている。そして、後壁２５の左右側は、上段側用被覆部２２から左右方向それぞれに突出する突出壁部２０Ｂ，２０Ｂとされている。このため、上段側用被覆部２２の乗客通路９Ｅを通ってきた乗客は、上段側階段構成部１６を昇りきり、フロア部１１に至ると、その内部スペースを広く感じ取ることができ、快適である。   In the present embodiment, the cross section perpendicular to the front-rear direction of the floor covering portion 20 is set larger in the upper stage covering portion 22 than the cross section perpendicular to the longitudinal direction. The left and right sides of the rear wall 25 are protruding wall portions 20B and 20B that protrude in the left-right direction from the upper-side covering portion 22, respectively. For this reason, a passenger who has passed through the passenger passage 9E of the upper-side covering portion 22 ascends the upper-stage staircase constituting portion 16 and reaches the floor portion 11, so that the interior space can be widely sensed and is comfortable. .

さらに本実施形態では、下段側用被覆部２１および上段側用被覆部２２は、その傾斜方向に沿う方向を長手方向として平行に並べられた複数本の枠材と、枠材の間に挟持される樹脂板との組み合わせによって形成されている。そして、下段側用被覆部２１および上段側用被覆部２２は、その傾斜方向である軸線方向を、フロア部用被覆部２０の後壁２５の後壁面に直交する方向に配置されている。さらに、下段側用被覆部２１および上段側用被覆部２２の前後端部は、ともにフロア部用被覆部２０の後壁２５に平行になるようにしている。このため、フロア部用被覆部２０の後壁２５の後壁面に直交する方向に対して傾斜させる場合に比べて、下段側用被覆部２１および上段側用被覆部２２の製造が容易になる。そして、特に下段側用被覆部２１の製造が容易になれば、接続部での精度を確保することができ、水の侵入を抑制することができる。   Furthermore, in the present embodiment, the lower-side covering portion 21 and the upper-side covering portion 22 are sandwiched between a plurality of frame members arranged in parallel with the direction along the inclined direction as the longitudinal direction, and the frame member. It is formed by a combination with a resin plate. The lower-side covering portion 21 and the upper-side covering portion 22 are arranged in a direction orthogonal to the rear wall surface of the rear wall 25 of the floor portion covering portion 20 with respect to the axial direction that is the inclination direction. Further, the front and rear end portions of the lower-side cover portion 21 and the upper-stage cover portion 22 are both parallel to the rear wall 25 of the floor portion cover portion 20. For this reason, compared with the case where it inclines with respect to the direction orthogonal to the rear wall surface of the rear wall 25 of the floor part covering part 20, manufacture of the lower stage side covering part 21 and the upper stage side covering part 22 becomes easy. And especially if manufacture of the lower stage side covering portion 21 becomes easy, accuracy at the connecting portion can be ensured, and water intrusion can be suppressed.
