Description

本発明は、主として、駅のホーム等から屋根上機器を見えにくくするための視線遮断部材を備える鉄道車両に関する。 The present invention mainly relates to a railway vehicle provided with a line-of-sight blocking member for making it difficult to see equipment on a roof from a platform of a station or the like.

鉄道車両の屋根上には、空調機器等の各種機器が配置されるが、デザイン上の観点から、これらの機器が外部から視認しにくい構成が求められる場合がある。 Various devices such as air conditioners are arranged on the roof of a railway vehicle. From the viewpoint of design, there is a case where a configuration in which these devices are difficult to be visually recognized from the outside is required.

特許文献１は、屋根上に空調機器が配置された構成の鉄道車両を開示する。この鉄道車両の屋根上であって車幅方向端部には、電気ケーブル等が通るケーブル通路が形成されている。このケーブル通路の車幅方向外側の側壁には、当該側壁から上方に延びるように形成された突起が設けられている。特許文献１の鉄道車両は、この突起により、屋根上に配置された空調機器を鉄道車両の外側から視認できないようにすることができる。 Patent Literature 1 discloses a railway vehicle having a configuration in which an air conditioner is arranged on a roof. A cable passage through which an electric cable or the like passes is formed on the roof of the railway vehicle and at an end in the vehicle width direction. A projection formed to extend upward from the side wall is provided on a side wall on the outside in the vehicle width direction of the cable passage. In the railway vehicle disclosed in Patent Literature 1, the protrusions make it possible to make the air conditioner disposed on the roof invisible from outside the railway vehicle.

特許文献２は、側構体の上端が、屋根構体側へ湾曲する構成の鉄道車両を開示する。特許文献２の鉄道車両は、側構体と屋根構体とを溶接することで、当該溶接箇所の近傍において側構体の方が高い位置になるように（即ち段差ができるように）構成されている。 Patent Literature 2 discloses a railway vehicle having a configuration in which an upper end of a side structure curves toward a roof structure. The railway vehicle disclosed in Patent Literature 2 is configured such that the side structure is welded to the roof structure so that the side structure is at a higher position in the vicinity of the welding point (that is, a step is formed).

特許文献１の鉄道車両は、車幅方向端部に配置された上方に延びる突起により屋根上機器を見えにくくする構成である。しかし、特許文献１は路面電車であり、一般の鉄道車両とは車両限界の形状が異なる。具体的には、一般の鉄道車両においては車両限界により、車幅方向端部の屋根上の空間の制約が大きい。即ち、屋根上の車両限界は、車幅方向の中央部が最も高く、車幅方向端部に近づくにつれて徐々に低くなる円弧状である。従って、車幅方向端部に位置する軒桁からは、屋根上の車両限界までの余裕が少ない。そのため、軒桁から鉛直方向上側に十分な長さの突起を設けることができない。 The railway vehicle disclosed in Patent Literature 1 has a configuration in which the on-roof equipment is hardly seen by an upwardly extending protrusion disposed at an end portion in the vehicle width direction. However, Patent Literature 1 is a tram, and the shape of the vehicle limit is different from a general railcar. Specifically, in a general railway vehicle, the space on the roof at the end in the vehicle width direction is greatly restricted due to the vehicle limit. In other words, the vehicle limit on the roof has an arc shape that is highest at the center in the vehicle width direction and gradually decreases toward the end in the vehicle width direction. Therefore, there is little margin from the eaves girder located at the end in the vehicle width direction to the vehicle limit on the roof. Therefore, it is not possible to provide a projection having a sufficient length vertically above the eaves girder.

特許文献２のように側構体の上端を湾曲させながら高く形成することで、側構体の最も高い位置が車幅方向中央側に寄るため、当該側構体の上端によって屋根上機器を見えにくくすることができる。しかし、この構成では側構体の大きさが大きくなるため、コストが高くなったり、製造が困難になったりする。一方、側構体の大きさを小さくした場合は、屋根上機器が見えてしまい、鉄道車両の見栄えが低下する。 By making the upper end of the side structure higher while curving the upper end of the side structure as in Patent Document 2, since the highest position of the side structure is closer to the center in the vehicle width direction, the upper end of the side structure makes it difficult to see the equipment on the roof. Can be. However, in this configuration, the size of the side structure is increased, so that the cost is increased and the manufacturing is difficult. On the other hand, when the size of the side structure is reduced, the equipment on the roof is visible, and the appearance of the railway vehicle is reduced.

本発明は以上の事情に鑑みてされたものであり、その主要な目的は、屋根上機器を見えにくくするための構成を有する鉄道車両において、構体の大きさを抑えつつ、良好な見栄えを実現した構成を提供することにある。 The present invention has been made in view of the above circumstances, and a main object of the present invention is to achieve a good appearance while suppressing the size of the structure in a railway vehicle having a configuration for making roof equipment difficult to see. It is to provide a customized configuration.

本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段とその効果を説明する。 The problem to be solved by the present invention is as described above. Next, means for solving the problem and its effects will be described.

本発明の観点によれば、以下の構成の鉄道車両が提供される。即ち、この鉄道車両は、構体と、屋根上機器と、視線遮断部材と、を備える。前記構体は、側構体と、屋根構体と、前記側構体と前記屋根構体を接続する軒桁と、を含む。前記屋根上機器は、前記屋根構体の上側に配置される。前記視線遮断部材は、前記構体と別部材であり、前記屋根構体の上側であって前記軒桁及び前記屋根構体の車幅方向端部の近傍に配置され、前記屋根上機器の全体が車体側方下部から視認できないように視線を遮る。前記視線遮断部材は、内側遮断部と、外側遮断部と、を備える。前記内側遮断部は、車幅方向外側に近づくにつれて下方に近づく湾曲形状である。前記外側遮断部は、前記内側遮断部の車幅方向外側に接続されており、車幅方向外側に近づく際の下方に近づく度合いが前記内側遮断部よりも大きい。車両正面視において、前記軒桁の外側の少なくとも１つの点から前記内側遮断部に引いた仮想接線よりも内側に、前記外側遮断部の下端が位置する。 According to an aspect of the present invention, a railway vehicle having the following configuration is provided. That is, this railway vehicle includes a structure, a roof device, and a line-of-sight blocking member. The structure includes a side structure, a roof structure, and an eave girder connecting the side structure and the roof structure. The on-roof equipment is arranged above the roof structure. The line of sight blocking member, the assembly and a separate member, wherein arranged in the vicinity of the eaves digits and the vehicle width direction end portions of the roof construction a upper roof structure, the whole body side of the roof on the equipment Block your gaze so you cannot see it from below. The line-of-sight blocking member includes an inner blocking section and an outer blocking section. The inner blocking portion has a curved shape approaching downward as approaching outward in the vehicle width direction. The outer blocking portion is connected to the outer side in the vehicle width direction of the inner blocking portion, and the degree of approaching downward when approaching the outer side in the vehicle width direction is greater than that of the inner blocking portion. In a front view of the vehicle, a lower end of the outer blocking portion is located inside a virtual tangent drawn from at least one point outside the eave girder to the inner blocking portion.

これにより、構体と視線遮断部材が別部材なので、屋根上機器への視線を構体によって遮断する構成と比較して、構体の大きさを抑えることができる。また、視線遮断部材の外側遮断部の形状により、駅のホーム等から側構体の上部を見上げた場合に構体と視線遮断部材が段差なく連続して見え易くなるので、鉄道車両の見栄えが良くなる。 Accordingly, since the structure and the line-of-sight blocking member are separate members, the size of the structure can be suppressed as compared with a configuration in which the line of sight to the on-roof equipment is blocked by the structure. In addition, due to the shape of the outside blocking portion of the line-of-sight blocking member, when the upper part of the side structure is looked up from the platform of the station or the like, the structure and the line-of-sight blocking member can be easily seen continuously without a step, so that the appearance of the railway vehicle is improved. .

本発明によれば、屋根上機器を見えにくくするための視線遮断部材を備えた鉄道車両において、構体の大きさを抑えつつ、良好な見栄えを実現した構成が実現できる。 ADVANTAGE OF THE INVENTION According to this invention, in the railway vehicle provided with the line-of-sight blocking member for making the on-roof equipment difficult to see, it is possible to realize a configuration that achieves a good appearance while suppressing the size of the structure.

図１に示すように、鉄道車両１は、車体２と、台車３と、を備える。車体２は、略箱状に構成された構体１０と、当該構体１０に設けられた各種装備品と、を備える。台車３は、車体２を支持するとともに、レール上を走行するための車輪を備えている。 As shown in FIG. 1, the railway vehicle 1 includes a vehicle body 2 and a bogie 3. The vehicle body 2 includes a substantially box-shaped structure 10 and various accessories provided in the structure 10. The bogie 3 supports the vehicle body 2 and includes wheels for traveling on rails.

構体１０は、台枠１１と、側構体１２と、屋根構体１３と、妻構体１５と、を備え、側構体１２と屋根構体１３との間には車両長手方向に延びる軒桁１４を有している。本実施形態の構体１０は、アルミニウム合金製であるが、別の材料（例えば、炭素鋼又はステンレス鋼）であっても良い。また、構体１０は、図４に示すように、２枚の板材の間に図略の補強部材が設けられたダブルスキン構造である。 The structure 10 includes an underframe 11, a side structure 12, a roof structure 13, and a wife structure 15, and an eave girder 14 extending in the vehicle longitudinal direction between the side structure 12 and the roof structure 13. ing. The structure 10 of the present embodiment is made of an aluminum alloy, but may be another material (for example, carbon steel or stainless steel). Further, as shown in FIG. 4, the structure 10 has a double skin structure in which a reinforcing member (not shown) is provided between two plate members.

台枠１１は、構体１０の底面部を構成している。台枠１１の下面には、台車３が取り付けられている。また、台枠１１の上面には床板が貼られており、当該床板には、図４に示すように、乗客が座るための座席２１が設けられている。 The underframe 11 constitutes a bottom surface of the structure 10. The cart 3 is attached to the lower surface of the underframe 11. Further, a floor plate is stuck on the upper surface of the underframe 11, and a seat 21 for a passenger to sit on is provided on the floor plate, as shown in FIG.

側構体１２は、構体１０の左右両方の側面部（車幅方向両端部に相当する部分）を構成している。側構体１２は、台枠１１の車幅方向両端部に溶接等により接続されている。また、側構体１２には、図１及び図２に示すように、窓２２及びドア２３が設けられている。 The side structures 12 constitute left and right side surfaces of the structure 10 (portions corresponding to both ends in the vehicle width direction). The side structures 12 are connected to both ends of the underframe 11 in the vehicle width direction by welding or the like. The side structure 12 is provided with a window 22 and a door 23 as shown in FIGS. 1 and 2.

屋根構体１３は、構体１０の上面部を構成している。屋根構体１３は、車幅方向内側に近づくに従って高さが高くなるように、即ち車両限界線８０に沿うように湾曲した形状である（図４参照）。なお、屋根上の車両限界線８０は、車幅方向の中央部が最も高く、かつ、車幅方向端部に近づくにつれて徐々に低くなる円弧状である。屋根構体１３の上側（外側）には、図１から図４に示すように、屋根上機器３０と、視線遮断部材４０と、歩み板５１と、取付台５２と、が設けられている。視線遮断部材４０、歩み板５１、及び取付台５２は、図３に示すように、屋根上機器３０を挟んで左右一対で設けられている。 The roof structure 13 constitutes the upper surface of the structure 10. The roof structure 13 has a shape that is curved so as to increase in height as approaching the inside in the vehicle width direction, that is, along the vehicle limit line 80 (see FIG. 4). The vehicle limit line 80 on the roof has an arc shape that is highest at the center in the vehicle width direction and gradually decreases as approaching the end in the vehicle width direction. On the upper side (outside) of the roof structure 13, as shown in FIGS. 1 to 4, the on-roof equipment 30, the line-of-sight blocking member 40, the step board 51, and the mount 52 are provided. As shown in FIG. 3, the line-of-sight blocking member 40, the step board 51, and the mounting table 52 are provided as a pair on the left and right with the on-roof equipment 30 interposed therebetween.

屋根上機器３０は、屋根構体１３の上側に配置される機器である。より詳細には、屋根上機器３０は、図３に示すように、車幅方向の中央を含みつつ、車幅方向外側に均等に広がるように配置されている。屋根上機器３０は、例えば、パンタグラフ及び空調機器であるが、それ以外の機器であっても良い。本実施形態では、１両の鉄道車両１に３つの屋根上機器３０が配置されているが、２つ以下であっても良いし、４つ以上であっても良い。また、空調機器等がハウジング等に覆われている場合であっても、当該ハウジング等を含めた構成が屋根上機器３０に相当する。 The on-roof device 30 is a device arranged above the roof structure 13. More specifically, as shown in FIG. 3, the on-roof equipment 30 is arranged so as to spread evenly outward in the vehicle width direction while including the center in the vehicle width direction. The on-roof equipment 30 is, for example, a pantograph and an air conditioner, but may be other equipment. In the present embodiment, three on-roof equipments 30 are arranged in one railcar 1, but may be two or less, or four or more. Further, even when the air conditioner or the like is covered with the housing or the like, the configuration including the housing or the like corresponds to the roof device 30.

視線遮断部材４０は、駅のホーム等から（即ち車体側方下部から）屋根上機器３０が視認できないように視線を遮る部材である。なお、視線遮断部材４０の形状、構造、及び取付方法等については、後述する。 The line-of-sight blocking member 40 is a member that blocks the line of sight so that the on-roof equipment 30 cannot be viewed from the platform of the station or the like (that is, from the lower side of the vehicle body). The shape, structure, mounting method and the like of the line-of-sight blocking member 40 will be described later.

歩み板５１は細長状の部材であり、歩み板５１の長手方向と、鉄道車両１の長手方向と、が一致するように配置されている。歩み板５１は、屋根上機器３０をメンテナンスする際に作業者が足を載せるための部材である。歩み板５１は、基本的には屋根上機器３０が存在する箇所の車幅方向外側に配置されている。なお、歩み板５１は、視線遮断部材４０を取り付ける台座としての機能も有する（詳細は後述）。 The step board 51 is an elongated member, and is arranged so that the longitudinal direction of the step board 51 and the longitudinal direction of the railway vehicle 1 match. The step board 51 is a member on which a worker places his / her feet when performing maintenance on the roof equipment 30. The step board 51 is basically arranged outside the location where the on-roof equipment 30 exists in the vehicle width direction. The step board 51 also has a function as a pedestal to which the line-of-sight blocking member 40 is attached (details will be described later).

歩み板５１は、後述の図５に示すように、２つの水平面支持部５１ａと、水平面部５１ｂと、を備える。２つの水平面支持部５１ａ及び水平面部５１ｂは、１枚の板材を折り曲げることで構成されているが、別部材として構成されていても良い。水平面支持部５１ａは、下端が屋根構体１３に溶接されており、屋根構体１３から上方に立ち上がるように構成されている。水平面支持部５１ａは、車幅方向に２つ並べて配置されており、当該２つの水平面支持部５１ａを接続するように水平面部５１ｂが設けられている。水平面部５１ｂは、平板状の部材であり、上述の作業者が足を載せるための部分である。 The walking board 51 includes two horizontal plane support parts 51a and a horizontal plane part 51b, as shown in FIG. 5 described later. The two horizontal surface support portions 51a and the horizontal surface portion 51b are configured by bending a single plate material, but may be configured as separate members. The lower end of the horizontal plane support portion 51a is welded to the roof structure 13, and is configured to rise upward from the roof structure 13. Two horizontal surface support portions 51a are arranged side by side in the vehicle width direction, and a horizontal surface portion 51b is provided so as to connect the two horizontal surface support portions 51a. The horizontal surface portion 51b is a plate-shaped member, and is a portion on which the above-mentioned operator places his or her feet.

取付台５２は、図３に示すように、車両長手方向で隣り合う歩み板５１の間、及び、屋根構体１３の車両長手方向の端部に配置されている。取付台５２は、正面断面視において歩み板５１と同形状であるが、少なくとも視線遮断部材４０を取り付けるための部分があれば良い。即ち、歩み板５１の作業者が歩くための箇所に相当する部分は取付台５２には不要である。取付台５２は、作業者が歩くためではなく、視線遮断部材４０を取り付ける台座として機能し、歩み板５１が存在しない部分を補う。なお、本実施形態において、歩み板５１と取付台５２とは別部材としたが、一体形状として車両長手方向全長に亘って延びる構成としてもよい。 As shown in FIG. 3, the mounting table 52 is arranged between the step boards 51 adjacent in the vehicle longitudinal direction and at an end of the roof structure 13 in the vehicle longitudinal direction. The mounting base 52 has the same shape as the step board 51 in a front cross-sectional view, but it is sufficient if there is at least a portion for mounting the line-of-sight blocking member 40. That is, the portion of the step board 51 corresponding to the location where the worker walks is not required for the mounting table 52. The mounting base 52 functions not as a base for the worker to walk but as a base for mounting the line-of-sight blocking member 40, and supplements a portion where the step board 51 does not exist. In the present embodiment, the step board 51 and the mounting table 52 are separate members, but may be formed as an integral shape and extend over the entire length in the vehicle longitudinal direction.

軒桁１４は、側構体１２と屋根構体１３の間に配置されており、側構体１２と屋根構体１３とを接続する。軒桁１４は、側構体１２と一体的に構成され、その後、屋根構体１３と溶接等により接続される。あるいは、軒桁１４は、屋根構体１３と一体的に構成され、その後、側構体１２と溶接等により接続される構成であっても良い。あるいは、軒桁１４は、側構体１２及び屋根構体１３と別部材であり、側構体１２及び屋根構体１３と溶接等により接続される構成であっても良い。 The eaves girder 14 is disposed between the side structure 12 and the roof structure 13 and connects the side structure 12 and the roof structure 13. The eaves girder 14 is formed integrally with the side structure 12, and is thereafter connected to the roof structure 13 by welding or the like. Alternatively, the eaves girder 14 may be configured integrally with the roof structure 13 and then connected to the side structure 12 by welding or the like. Alternatively, the eave girder 14 may be a member separate from the side structure 12 and the roof structure 13 and may be connected to the side structure 12 and the roof structure 13 by welding or the like.

また、図４に示すように、軒桁１４（詳細には１４の上面）は、湾曲状に構成されている。軒桁１４には、車幅方向内側の端部近傍において、段差が形成されている。軒桁１４の段差及び屋根構体１３の一部は、屋根構体１３の上面を流れる雨水を集めるための雨樋２４として機能する。雨樋２４が集めた雨水は、例えば鉄道車両１の車両長手方向端部に設けられた図略の排水管から外部に排出される。 Further, as shown in FIG. 4, the eaves girder 14 (specifically, the upper surface of 14) is configured in a curved shape. A step is formed in the eaves girder 14 near the inner end in the vehicle width direction. The step of the eaves girder 14 and a part of the roof structure 13 function as a rain gutter 24 for collecting rainwater flowing on the upper surface of the roof structure 13. The rainwater collected by the rain gutter 24 is discharged to the outside, for example, from a drain pipe (not shown) provided at a longitudinal end of the railway vehicle 1.

妻構体１５は、構体１０の前後面部（車両長手方向の両端部に相当する部分）を構成している。妻構体１５には、連結された鉄道車両１へ移動するための開口部２５が形成されている。 The wife structure 15 forms front and rear surfaces of the structure 10 (portions corresponding to both ends in the vehicle longitudinal direction). An opening 25 for moving to the connected railway vehicle 1 is formed in the wife structure 15.

次に、図４及び図５を参照して、視線遮断部材４０について詳細に説明する。図５は、視線遮断部材４０の近傍の拡大正面断面図である。視線遮断部材４０は、アルミニウム合金製であり、構体１０とは別部材として、押出成形で成形されている。視線遮断部材４０は、屋根構体１３の上側であって、当該屋根構体１３の車幅方向外側の端部近傍（即ち軒桁１４の近傍）に配置されている。また、視線遮断部材４０は、図３に示すように、鉄道車両１の車両長手方向の全体にわたって設けられている。 Next, the visual line blocking member 40 will be described in detail with reference to FIGS. FIG. 5 is an enlarged front sectional view near the line-of-sight blocking member 40. The line-of-sight blocking member 40 is made of an aluminum alloy, and is formed by extrusion as a separate member from the structure 10. The line-of-sight blocking member 40 is disposed above the roof structure 13 and near the end of the roof structure 13 on the outer side in the vehicle width direction (that is, near the eaves girder 14). The line-of-sight blocking member 40 is provided over the entire railcar 1 in the vehicle longitudinal direction, as shown in FIG.

視線遮断部材４０は、図５に示すように、内側支持部４１と、外側支持部４２と、接触部４３と、離間部４４と、内側遮断部４５と、外側遮断部４６と、を備える。視線遮断部材４０（詳細には内側遮断部４５と外側遮断部４６）は、図４に示す車両限界線８０に沿うように形成されている。 As shown in FIG. 5, the line-of-sight blocking member 40 includes an inner supporting portion 41, an outer supporting portion 42, a contact portion 43, a separating portion 44, an inner blocking portion 45, and an outer blocking portion 46. The line-of-sight blocking members 40 (specifically, the inner blocking portion 45 and the outer blocking portion 46) are formed along the vehicle limit line 80 shown in FIG.

内側支持部４１は、高さ方向に延びる部分である。内側支持部４１の上部には、内側遮断部４５が位置している。内側支持部４１の下部には、離間部４４が位置している。 The inner support portion 41 is a portion extending in the height direction. Above the inner supporting portion 41, an inner blocking portion 45 is located. A separation portion 44 is located below the inner support portion 41.

外側支持部４２は、高さ方向に延びる部分であり、内側支持部４１よりも車幅方向外側に位置している。外側支持部４２の上端は、内側支持部４１の上端よりも下方に位置している。外側支持部４２の上部には内側遮断部４５と外側遮断部４６の境界部分が位置している。外側支持部４２の下部は、リベット又はボルト等の固定具６０によって、歩み板５１の水平面支持部５１ａに取り付けられている。このように、視線遮断部材４０を固定具６０で接続することで溶接が不要となり溶接歪みが発生しないので、鉄道車両１の見栄えを良くすることができる。 The outer support portion 42 is a portion extending in the height direction, and is located outside the inner support portion 41 in the vehicle width direction. The upper end of the outer support part 42 is located lower than the upper end of the inner support part 41. A boundary portion between the inner blocking portion 45 and the outer blocking portion 46 is located above the outer supporting portion 42. The lower portion of the outer support portion 42 is attached to the horizontal support portion 51a of the walking board 51 by a fixture 60 such as a rivet or a bolt. In this manner, by connecting the line-of-sight blocking member 40 with the fixture 60, welding becomes unnecessary and welding distortion does not occur, so that the appearance of the railway vehicle 1 can be improved.

特に、視線遮断部材４０は、歩み板５１（詳細には水平面部５１ｂの車幅方向外側の端部）に取り付けられている。屋根構体１３は高い水密性と強度が要求されるため、屋根構体１３に直接、固定具６０で視線遮断部材４０を取り付けることは好ましくない。この点、本実施形態では、あらかじめ溶接により屋根構体１３に取り付けられた歩み板５１及び取付台５２に視線遮断部材４０が取り付けられているため、固定具６０を用いても水密性と強度が低下することはない。 In particular, the line-of-sight blocking member 40 is attached to the step board 51 (specifically, the outer end of the horizontal surface portion 51b in the vehicle width direction). Since the roof structure 13 is required to have high watertightness and strength, it is not preferable to directly attach the line-of-sight blocking member 40 to the roof structure 13 with the fixture 60. In this regard, in the present embodiment, since the line-of-sight blocking member 40 is attached to the step board 51 and the attachment base 52 that have been attached to the roof structure 13 by welding in advance, the watertightness and strength are reduced even when the fixture 60 is used. I will not do it.

また、視線遮断部材４０を歩み板５１に取り付けることで、視線遮断部材４０を屋根構体１３に直接取り付ける構成と比較して、視線遮断部材４０の大きさを抑えることもできる。また、視線遮断部材４０を屋根構体１３に直接、溶接や固定具により取り付けた場合には、雨水等による漏水の可能性があるが、本実施形態の構成により漏水のリスクを低減できる。 In addition, by attaching the line-of-sight blocking member 40 to the step board 51, the size of the line-of-sight blocking member 40 can be suppressed as compared with a configuration in which the line-of-sight blocking member 40 is directly attached to the roof structure 13. Further, when the line-of-sight blocking member 40 is directly attached to the roof structure 13 by welding or a fixing tool, there is a possibility of water leakage due to rainwater or the like, but the configuration of the present embodiment can reduce the risk of water leakage.

更に、本実施形態のように、歩み板５１が、鉄道車両１の車両長手方向の一部にしか設けられない場合であっても、取付台５２を追加で設けることで、視線遮断部材４０の大きさを低減できる。 Furthermore, even when the step board 51 is provided only in a part of the railway vehicle 1 in the vehicle longitudinal direction as in the present embodiment, the additional provision of the mount 52 enables the line-of-sight blocking member 40 to be provided. The size can be reduced.

接触部４３は、水平面を有しており、歩み板５１の水平面部５１ｂと面接触する。接触部４３は、車幅方向の内側と外側にそれぞれ設けられており、内側の接触部４３は、固定具６０によって歩み板５１の水平面部５１ｂに取り付けられている。 The contact portion 43 has a horizontal surface, and makes surface contact with the horizontal surface portion 51 b of the walking board 51. The contact portions 43 are provided on the inside and outside in the vehicle width direction, respectively, and the inside contact portions 43 are attached to the horizontal surface portion 51 b of the walking board 51 by the fixtures 60.

離間部４４は、２つの接触部４３の間に位置している。離間部４４は、接触部４３と連続するように構成されるとともに、歩み板５１（水平面部５１ｂ）から離れるように形成されており、当該歩み板５１（水平面部５１ｂ）と接触しない。このように、離間部４４を設けることで、視線遮断部材４０と歩み板５１の接触面積を減らすことができるので、歩み板５１及び視線遮断部材４０の平面度が低い場合であっても視線遮断部材４０のガタツキを抑えることができる。 The separation part 44 is located between the two contact parts 43. The separation section 44 is configured to be continuous with the contact section 43 and formed so as to be separated from the step board 51 (horizontal plane section 51b), and does not contact the step board 51 (horizontal plane section 51b). Since the contact area between the line-of-sight blocking member 40 and the walking plate 51 can be reduced by providing the separation portion 44 in this manner, the line-of-sight blocking even when the flatness of the walking plate 51 and the line-of-sight blocking member 40 is low. The rattling of the member 40 can be suppressed.

内側遮断部４５（特に上側（外側）の面）は、湾曲状に構成されており、車幅方向外側に近づくにつれて下方に近づく形状である。内側遮断部４５の車幅方向内側の端部は、歩み板５１を歩く作業者の衣服等に引っ掛からないように断面円状に構成されている。 The inner blocking portion 45 (particularly, the upper (outer) surface) is formed in a curved shape, and has a shape approaching downward as approaching outward in the vehicle width direction. The inside end of the inside blocking portion 45 in the vehicle width direction is formed in a circular cross section so as not to be caught by clothes or the like of an operator walking on the step board 51.

外側遮断部４６は、内側遮断部４５の車幅方向外側の端部に位置している。外側遮断部４６（特に上側（外側）の面）は、内側遮断部４５と同様に、湾曲状に構成されており、車幅方向外側に近づくにつれて下方に近づく形状である。 The outer blocking portion 46 is located at an outer end of the inner blocking portion 45 in the vehicle width direction. The outer blocking portion 46 (particularly, the upper (outer) surface) is formed in a curved shape similarly to the inner blocking portion 45, and has a shape approaching downward as approaching outward in the vehicle width direction.

内側遮断部４５及び外側遮断部４６は、駅のホーム等から屋根上機器３０を見えにくくするための部材である。従って、軒桁１４（詳細には軒桁１４の上面（表面））と、屋根上機器３０の上面（表面）と、を結ぶ仮想直線８１を考えた場合に、内側遮断部４５（詳細には内側遮断部４５の上面）は、当該仮想直線８１（図５）の上側に位置する。 The inner blocking part 45 and the outer blocking part 46 are members for making it difficult to see the on-roof equipment 30 from a station platform or the like. Therefore, when a virtual straight line 81 connecting the eaves girder 14 (specifically, the upper surface (surface) of the eaves girder 14) and the upper surface (surface) of the roof equipment 30 is considered, the inner blocking part 45 (specifically, The upper surface of the inner blocking portion 45 is located above the virtual straight line 81 (FIG. 5).

また、本実施形態では、駅のホーム等から側構体１２の上部を見上げた場合に軒桁１４と視線遮断部材４０が段差なく連続して見えるように、内側遮断部４５と外側遮断部４６の形状を異ならせている。具体的には、内側遮断部４５と外側遮断部４６は曲率半径が異なり、外側遮断部４６は、内側遮断部４５より曲率半径が小さい。即ち、車幅方向外側に同じ長さだけ進んだときにおいて、外側遮断部４６の方が内側遮断部４５よりも下方に進む長さが長い。換言すると、外側遮断部４６は、内側遮断部４５から更に内側（下側）に湾曲する（曲がる）ように構成されている。更に換言すると、軒桁１４と内側遮断部４５の仮想共通接線８２（図５）よりも内側（下側）に外側遮断部４６の下端が位置するように構成されている。 Further, in the present embodiment, when the upper part of the side structure 12 is looked up from the platform of the station or the like, the eaves girder 14 and the line-of-sight shielding member 40 can be seen continuously without any level difference. The shape is different. Specifically, the radius of curvature of the inner blocking portion 45 is different from that of the outer blocking portion 46, and the radius of curvature of the outer blocking portion 46 is smaller than that of the inner blocking portion 45. That is, when the vehicle travels the same length outward in the vehicle width direction, the length of the outer blocking portion 46 that travels below the inner blocking portion 45 is longer. In other words, the outer blocking portion 46 is configured to be further inward (downward) from the inner blocking portion 45 (bend). In other words, the lower end of the outer blocking part 46 is located inside (below) the virtual common tangent 82 (FIG. 5) between the eaves girder 14 and the inner blocking part 45.

また、視線遮断部材４０は、軒桁１４の段差部と外側遮断部４６との間に隙間が存在するように構成されている。更に、本実施形態では、図５に示すように、軒桁１４と視線遮断部材４０の隙間に、軒桁１４と屋根構体１３の継手（溶接を行う際の繋ぎ目）が位置している。この構成により、当該隙間に溶接機を挿入することができるので、屋根構体１３に視線遮断部材４０を先に取り付けた後に、側構体１２（軒桁１４）と屋根構体１３とを溶接して接続することができる。 The line-of-sight blocking member 40 is configured such that a gap exists between the step portion of the eaves girder 14 and the outside blocking portion 46. Further, in the present embodiment, as shown in FIG. 5, a joint between the eaves girder 14 and the roof structure 13 (a joint for welding) is located in a gap between the eaves girder 14 and the line-of-sight blocking member 40. According to this configuration, a welding machine can be inserted into the gap, so that the side structure 12 (eave girder 14) and the roof structure 13 are welded and connected after the line-of-sight blocking member 40 is attached to the roof structure 13 first. can do.

仮に、軒桁に視線遮断部材の機能を持たせた場合、軒桁が高さ方向だけでなく車幅方向の寸法が大きくなるため、雨水を受ける面積も大きくなる。この場合、軒桁に降った雨水は側構体を通るため、軒桁を大きくすることで側構体に流れる雨水が多くなる。そのため、雨水中の汚れ成分により側構体が汚れ易くなるとともに、開扉した窓及びドアから車内に入り込む雨水の量が多くなる。更に、押出成形を行う場合は製造可能な大きさに上限があるため、屋根上機器への視線を完全に遮断する大きさの軒桁がワンパーツとして製造できない可能性があり、この場合、当該軒桁を構成する部材同士を溶接等により接続する必要があり、作業工数が増大する。この点、本実施形態では、軒桁１４とは別に視線遮断部材４０を設ける構成であるため、軒桁１４の車幅方向の大きさを抑えることができるので、窓２２及びドア２３の汚れを低減できる。特に、視線遮断部材４０と軒桁１４との間には隙間が設けられているので、視線遮断部材４０に降った雨水は、当該隙間に設けられた雨樋２４を介して排出されるので、側構体１２に流れる雨水の量を少なくすることができる。更に、視線遮断部材４０は、構体１０と別部材であり、構体１０のように大きな荷重が負荷されず、高い強度が要求されないので、視線遮断部材４０を容易に製造でき、ローコスト及び軽量化を図ることができる。 If the eaves girder is provided with the function of a line-of-sight blocking member, the eaves girder becomes larger not only in the height direction but also in the vehicle width direction, so that the area for receiving rainwater also becomes larger. In this case, since the rainwater falling on the eaves girder passes through the side structure, increasing the eaves girder increases the amount of rainwater flowing to the side structure. Therefore, the side structure is easily stained by the dirt component in the rainwater, and the amount of rainwater that enters the vehicle through the opened windows and doors increases. Furthermore, when extrusion molding is performed, since there is an upper limit to the size that can be manufactured, there is a possibility that an eaves girder large enough to completely block the line of sight to the equipment on the roof may not be manufactured as a single part. It is necessary to connect members constituting the eaves girder by welding or the like, which increases the number of work steps. In this regard, in this embodiment, since the line-of-sight blocking member 40 is provided separately from the eaves girder 14, the size of the eaves girder 14 in the vehicle width direction can be suppressed. Can be reduced. In particular, since a gap is provided between the line-of-sight blocking member 40 and the eaves girder 14, rainwater falling on the line-of-sight blocking member 40 is discharged through the rain gutter 24 provided in the gap. The amount of rainwater flowing to the side structure 12 can be reduced. Furthermore, since the line-of-sight blocking member 40 is a separate member from the structure 10 and is not subjected to a large load unlike the structure 10 and does not require high strength, the line-of-sight blocking member 40 can be easily manufactured, and low cost and light weight can be achieved. Can be planned.

次に、図６を参照して、鉄道車両１の変形例について説明する。図６は、変形例に係る鉄道車両１の視線遮断部材４０の近傍の拡大正面断面図である。なお、本変形例の説明において、同一又は類似の部材には図面に同一の符号を付し、説明を省略することがある。 Next, a modified example of the railway vehicle 1 will be described with reference to FIG. FIG. 6 is an enlarged front sectional view near the line-of-sight blocking member 40 of the railway vehicle 1 according to the modification. In the description of the modification, the same or similar members are denoted by the same reference numerals in the drawings, and description thereof may be omitted.

上記の実施形態では、軒桁１４の上面は湾曲状であるが、本変形例では軒桁１４の上面は傾斜面状に構成されている。本変形例では、上記の実施形態のように仮想共通接線８２を引くことはできないため、同じ観点で視線遮断部材４０の形状を説明できない。しかし、本変形例の場合であっても、軒桁１４の少なくとも１点（例えば図６の黒丸で示した箇所）から視線遮断部材４０の内側遮断部４５に引いた仮想接線８３を考え、当該仮想接線８３よりも内側に外側遮断部４６の下端が位置していれば、視線遮断部材４０と軒桁１４が段差なく連続して見えるようにすることができる。 In the above embodiment, the upper surface of the eaves girder 14 is curved, but in the present modification, the upper surface of the eaves girder 14 is configured to be inclined. In this modification, the virtual common tangent line 82 cannot be drawn as in the above-described embodiment, so that the shape of the line-of-sight blocking member 40 cannot be described from the same viewpoint. However, even in the case of the present modified example, a virtual tangent line 83 drawn from at least one point of the eaves girder 14 (for example, a point indicated by a black circle in FIG. 6) to the inner blocking part 45 of the gaze blocking member 40 is considered. If the lower end of the outer blocking part 46 is located inside the virtual tangent line 83, the line-of-sight blocking member 40 and the eaves girder 14 can be seen continuously without any level difference.

なお、内側遮断部４５及び外側遮断部４６も湾曲状に限られず、少なくとも一方が傾斜面状に構成されていても良い。例えば、内側遮断部４５及び外側遮断部４６の両方が傾斜面状である場合、内側遮断部４５の傾きよりも外側遮断部４６の傾きを垂直に近くする必要がある。また、内側遮断部４５と外側遮断部４６の一方が湾曲状で他方が傾斜面状である場合であっても、上記の実施形態及び変形例と同様に、内側遮断部４５よりも外側遮断部４６の方が、車幅方向外側に近づく際の下方に近づく度合いが大きければ良い。 In addition, the inner blocking part 45 and the outer blocking part 46 are not limited to the curved shape, and at least one of them may be configured in an inclined surface shape. For example, when both the inner blocking part 45 and the outer blocking part 46 are inclined surfaces, the inclination of the outer blocking part 46 needs to be closer to the vertical than the tilt of the inner blocking part 45. Further, even when one of the inner blocking portion 45 and the outer blocking portion 46 has a curved shape and the other has an inclined surface shape, similarly to the above-described embodiment and the modified example, the outer blocking portion is larger than the inner blocking portion 45. It suffices that 46 is closer to the lower side when approaching the outside in the vehicle width direction.

以上に説明したように、鉄道車両１は、構体１０と、屋根上機器３０と、視線遮断部材４０と、を備える。構体１０は、側構体１２と、屋根構体１３と、側構体１２と屋根構体１３を接続する軒桁１４と、を含む。屋根上機器３０は、屋根構体１３の上側に配置される。視線遮断部材４０は、構体１０と別部材であり、屋根構体１３の上側であって軒桁１４及び屋根構体１３の車幅方向端部の近傍に配置され、屋根上機器３０の少なくとも一部が車体側方下部から視認できないように視線を遮る。視線遮断部材４０は、内側遮断部４５と、外側遮断部４６と、を備える。内側遮断部４５は、車幅方向外側に近づくにつれて下方に近づく形状である。外側遮断部４６は、内側遮断部４５の車幅方向外側に接続されており、車幅方向外側に近づく際の下方に近づく度合いが内側遮断部４５よりも大きい。 As described above, the railway vehicle 1 includes the structure 10, the roof equipment 30, and the line-of-sight blocking member 40. The structure 10 includes a side structure 12, a roof structure 13, and an eave girder 14 connecting the side structure 12 and the roof structure 13. The on-roof equipment 30 is arranged above the roof structure 13. The line-of-sight blocking member 40 is a separate member from the structure 10, is disposed above the roof structure 13, near the eaves girder 14 and the vehicle width direction ends of the roof structure 13, and at least a part of the on-roof equipment 30. The line of sight is blocked so that it cannot be seen from the lower side of the vehicle. The line-of-sight blocking member 40 includes an inner blocking section 45 and an outer blocking section 46. The inside blocking portion 45 is shaped so as to approach downward as it approaches the outside in the vehicle width direction. The outer blocking portion 46 is connected to the outer side in the vehicle width direction of the inner blocking portion 45, and the degree of approaching downward when approaching the outer side in the vehicle width direction is greater than that of the inner blocking portion 45.

これにより、構体１０と視線遮断部材４０が別部材なので、屋根上機器３０への視線を構体１０（軒桁１４等）によって遮断する構成と比較して、構体１０の大きさを抑えることができる。また、視線遮断部材４０の外側遮断部４６の形状により、駅のホーム等から側構体１２の上部を見上げた場合に構体１０と視線遮断部材４０が段差なく連続して見え易くなるので、鉄道車両１の見栄えが良くなる。 Accordingly, since the structure 10 and the line-of-sight blocking member 40 are separate members, the size of the structure 10 can be reduced as compared with a configuration in which the line of sight to the roof equipment 30 is blocked by the structure 10 (eave girder 14 or the like). . In addition, due to the shape of the outside blocking portion 46 of the line-of-sight blocking member 40, the structure 10 and the line-of-sight blocking member 40 can be easily viewed continuously without any level difference when looking up at the upper part of the side structure 12 from a station platform or the like. 1 looks better.

また、鉄道車両１において、内側遮断部４５は湾曲状である。車両正面視において、軒桁１４の外側の少なくとも１つの点から内側遮断部４５に引いた仮想接線８３よりも内側に、外側遮断部４６の下端が位置する。 Further, in the railway vehicle 1, the inner blocking portion 45 is curved. As viewed from the front of the vehicle, the lower end of the outer blocking portion 46 is located inside a virtual tangent 83 drawn from at least one point outside the eaves girder 14 to the inner blocking portion 45.

これにより、構体１０と視線遮断部材４０が段差なく連続して見え易くなるので、鉄道車両１の見栄えを一層向上させることができる。 Thereby, the structure 10 and the line-of-sight blocking member 40 are easily visible continuously without any level difference, so that the appearance of the railway vehicle 1 can be further improved.

また、鉄道車両１において、軒桁１４と内側遮断部４５は湾曲状である。車両正面視において、軒桁１４と内側遮断部４５の仮想共通接線８２よりも内側に外側遮断部４６の下端が位置する。 Further, in the railway vehicle 1, the eave girder 14 and the inner blocking portion 45 are curved. When viewed from the front of the vehicle, the lower end of the outer blocking portion 46 is located inside the virtual common tangent 82 between the eaves girder 14 and the inner blocking portion 45.

これにより、軒桁１４と視線遮断部材４０の両方を湾曲状にすることで視覚的に一体感がでるため、鉄道車両１の見栄えを一層向上させることができる。 Thereby, since the eaves girder 14 and the line-of-sight blocking member 40 are both curved, a sense of unity can be obtained visually, so that the appearance of the railway vehicle 1 can be further improved.

また、鉄道車両１において、外側遮断部４６は、湾曲状であり、内側遮断部４５よりも曲率半径が小さい。 Further, in the railway vehicle 1, the outer blocking portion 46 is curved, and has a smaller radius of curvature than the inner blocking portion 45.

このように外側遮断部４６も湾曲状にすることで、外側遮断部４６を折り目が付くように折り曲げた構成と比較して、内側遮断部４５と外側遮断部４６の境界が目立たなくなるので、鉄道車両１の見栄えを一層向上させることができる。 Since the outer blocking portion 46 is also curved in this way, the boundary between the inner blocking portion 45 and the outer blocking portion 46 is less noticeable than in a configuration in which the outer blocking portion 46 is bent so as to be creased. The appearance of the vehicle 1 can be further improved.

また、鉄道車両１において、視線遮断部材４０の内側遮断部４５の外側の面が、屋根上機器３０と軒桁１４との表面を結ぶ仮想直線８１より外側に位置する。 Further, in the railcar 1, the outer surface of the inner blocking portion 45 of the line-of-sight blocking member 40 is located outside a virtual straight line 81 connecting the surfaces of the roof equipment 30 and the eaves girder 14.

これにより、視線遮断部材４０により屋根上機器３０の略全部が車体側方下部から視認できないため、鉄道車両１の見栄えを一層向上させることができる。 Thereby, since almost all of the on-roof equipment 30 cannot be visually recognized from the lower part on the side of the vehicle body by the line-of-sight blocking member 40, the appearance of the railway vehicle 1 can be further improved.

また、鉄道車両１において、車幅方向における軒桁１４と視線遮断部材４０との間に隙間が存在する。 In the railcar 1, a gap exists between the eaves girder 14 and the line-of-sight blocking member 40 in the vehicle width direction.

これにより、雨水が側構体１２の外側に落ちにくくなるため、鉄道車両１の汚れを低減できる。 This makes it difficult for rainwater to fall to the outside of the side structure 12, so that the stain on the railway vehicle 1 can be reduced.

また、鉄道車両１において、構体１０は、ダブルスキン構造である。軒桁１４と屋根構体１３との継手が、軒桁１４と視線遮断部材４０との間に相当する位置に存在する。 In the railway vehicle 1, the structure 10 has a double skin structure. The joint between the eaves girder 14 and the roof structure 13 exists at a position corresponding to between the eaves girder 14 and the line-of-sight blocking member 40.

これにより、軒桁１４と視線遮断部材４０の隙間が十分な大きさであれば、この隙間から側構体１２と屋根構体１３の接続作業を行うことができる。従って、六面体からなる構体１０の接続作業前に先立って屋根構体１３に視線遮断部材４０を取り付けることができる。 Thus, if the gap between the eaves girder 14 and the line-of-sight blocking member 40 is sufficiently large, the connection work between the side structure 12 and the roof structure 13 can be performed from this gap. Therefore, the line-of-sight blocking member 40 can be attached to the roof structure 13 before connecting the hexahedral structure 10.

また、鉄道車両１において、屋根構体１３の上側には、車両長手方向に延びる歩み板５１が配置されている。視線遮断部材４０は、歩み板５１の上側に配置されている。 In the railway vehicle 1, a step board 51 extending in the vehicle longitudinal direction is disposed above the roof structure 13. The line-of-sight blocking member 40 is arranged above the step board 51.

これにより、歩み板５１の高さに相当する分だけ視線遮断部材４０の大きさを抑えることができる。 Thus, the size of the line-of-sight blocking member 40 can be reduced by an amount corresponding to the height of the step board 51.

また、鉄道車両１は、視線遮断部材４０と、歩み板５１と、が固定具６０によって固定されている。 In the railway vehicle 1, the line-of-sight blocking member 40 and the step board 51 are fixed by the fixture 60.

このように固定具６０で接続することで溶接が不要となり溶接歪みが発生しないので、鉄道車両１の見栄えが一層良くなる。 By connecting with the fixture 60 in this manner, welding becomes unnecessary and welding distortion does not occur, so that the appearance of the railway vehicle 1 is further improved.

また、鉄道車両１において、視線遮断部材４０は、接触部４３と、離間部４４と、を備える。接触部４３は、歩み板５１と固定具６０によって固定される部分であり、当該歩み板５１の上面と面接触する。離間部４４は、接触部４３と連続するように構成されるとともに、歩み板５１から離れるように形成されており、当該歩み板５１と接触しない。 Further, in the railway vehicle 1, the line-of-sight blocking member 40 includes a contact part 43 and a separation part 44. The contact portion 43 is a portion fixed by the step board 51 and the fixture 60, and makes surface contact with the upper surface of the step board 51. The separation section 44 is configured to be continuous with the contact section 43 and formed so as to be separated from the step board 51, and does not contact the step board 51.

これにより、歩み板５１及び視線遮断部材４０の平面度が低い場合であっても視線遮断部材４０のガタツキを抑えることができる。 Thereby, even if the flatness of the walking board 51 and the line-of-sight blocking member 40 is low, rattling of the line-of-sight blocking member 40 can be suppressed.

また、鉄道車両１は、歩み板５１の車幅方向外側の端部に視線遮断部材４０が配置されている。 Further, in the railway vehicle 1, the line-of-sight blocking member 40 is disposed at an outer end of the step board 51 in the vehicle width direction.

これにより、視線遮断部材４０を車幅方向外側に近づけて配置することで、視線遮断部材４０自体の大きさを抑えることができる。また、メンテナンス時においても屋根上機器３０へのアクセスを妨げない。 Thus, by arranging the line-of-sight blocking member 40 closer to the outside in the vehicle width direction, the size of the line-of-sight blocking member 40 itself can be suppressed. In addition, even during maintenance, access to the on-roof equipment 30 is not hindered.

以上に本発明の好適な実施の形態及び変形例を説明したが、上記の構成は例えば以下のように変更することができる。 Although the preferred embodiments and modified examples of the present invention have been described above, the above configuration can be changed as follows, for example.

構体１０を構成する台枠１１〜妻構体１５の構造及び形状は任意である。例えば、台枠１１〜妻構体１５は、ダブルスキン構造に限られず、シングルスキン構造であっても良い。また、屋根構体１３の上面は、曲面ではなく、平面（傾斜面又は水平面）であっても良い。 The structure and shape of the underframe 11 to the wife structure 15 constituting the structure 10 are arbitrary. For example, the underframe 11 to the wife structure 15 are not limited to the double skin structure, and may have a single skin structure. Further, the upper surface of the roof structure 13 may be a flat surface (inclined surface or horizontal surface) instead of a curved surface.

視線遮断部材４０の構造及び形状は任意である。例えば、内側遮断部４５及び外側遮断部４６を支持する部材は１つであっても良いし、離間部４４を形成しなくても良い。また、視線遮断部材４０は、アルミニウム合金製に限られず、例えば、ステンレス鋼製又は炭素鋼製であっても良い。また、視線遮断部材４０は、歩み板５１を介さずに、屋根構体１３に直接取り付けられていても良い。また、視線遮断部材４０は、鉄道車両１の車両長手方向の一部にのみ設けられていても良い。また、視線遮断部材４０は、押出成形により一体的に成形されているが、複数の部材を接続した構成であっても良い（例えば内側遮断部４５と外側遮断部４６が別部材であっても良い）。 The structure and shape of the line-of-sight blocking member 40 are arbitrary. For example, the number of members that support the inner blocking portion 45 and the outer blocking portion 46 may be one, or the separated portion 44 may not be formed. Further, the line-of-sight blocking member 40 is not limited to being made of an aluminum alloy, and may be made of, for example, stainless steel or carbon steel. Further, the line-of-sight blocking member 40 may be directly attached to the roof structure 13 without going through the step board 51. Further, the line-of-sight blocking member 40 may be provided only in a part of the railway vehicle 1 in the vehicle longitudinal direction. Further, the line-of-sight blocking member 40 is integrally formed by extrusion, but may have a configuration in which a plurality of members are connected (for example, even if the inner blocking portion 45 and the outer blocking portion 46 are separate members). good).
