Description

本発明は、屋根構体と、屋根構体に結合された固定部材と、固定部材を介して屋根構体に結合され、隣接して軌道方向に並ぶ少なくとも２枚の天井パネルと、を備える鉄道車両に関するものである。 The present invention relates to a railroad vehicle including a roof structure, a fixing member connected to the roof structure, and at least two ceiling panels connected to the roof structure via the fixing member and arranged adjacent to each other in the track direction. Is.

従来、図７に示すように、通勤列車等の鉄道車両５０は、台枠５２１、側構体５２２、屋根構体５２３、妻構体（不図示）により構成される６面体の車体５２を有しており、車体５２内部は客室５３として使用されている。また、客室５３の内壁は、床板パネル５３４、内装パネル５３３、側天井パネル５３２、天井パネル５３１により構成されている。 Conventionally, as shown in FIG. 7, a railroad vehicle 50 such as a commuter train has a hexahedral body 52 composed of an underframe 521, a side structure 522, a roof structure 523, and a wife structure (not shown). The inside of the vehicle body 52 is used as a guest room 53. The inner wall of the guest room 53 is composed of a floor plate panel 534, an interior panel 533, a side ceiling panel 532, and a ceiling panel 531.

ここで、天井パネル５３１の固定について着目する。天井パネル５３１は、図８に示すように、結合部材５３５を有している。該結合部材５３５が、屋根構体５２３に結合されている固定部材５２４に結合されることで、天井パネル５３１は屋根構体５２３に結合され、固定されている。 Here, attention is paid to the fixing of the ceiling panel 531. As shown in FIG. 8, the ceiling panel 531 has a connecting member 535. By connecting the connecting member 535 to the fixing member 524 connected to the roof structure 523, the ceiling panel 531 is connected to and fixed to the roof structure 523.

鉄道車両５０は、１両当たり、軌道方向の長さが約２０ｍであり、天井パネル５３１は、１枚当たり、軌道方向の長さが２ｍ程度である。よって、天井パネル５３１は、鉄道車両５０の１両あたりで、軌道方向に約１０枚並んで配設され、客室５３の天井を構成している。このとき、客室５３の美観を保つために、客室５３から見て、それぞれの天井パネル５３１の高さが一致して固定されていることが望ましい。 The railroad vehicle 50 has a length of about 20 m in the track direction per vehicle, and the ceiling panel 531 has a length of about 2 m in the track direction per vehicle. Therefore, about 10 ceiling panels 531 are arranged side by side in the track direction per one of the railroad vehicles 50, and constitute the ceiling of the passenger cabin 53. At this time, in order to maintain the aesthetic appearance of the guest room 53, it is desirable that the heights of the ceiling panels 531 are matched and fixed when viewed from the guest room 53.

しかし、天井パネル５３１には、成形後の収縮等による形状のばらつき（寸法のばらつきや、微少な捻じれ等）が生じているため、天井パネル５３１を直接に固定部材５２４に結合すると、上記した形状のばらつきや、微少な捻じれにより、隣り合う天井パネル５３１相互間で高さが一致せずに段差が生じてしまうなど、客室５３の美観を損ねるおそれがある。そこで、結合部材５３５と固定部材５２４の間に、硬質塩ビ製のスペーサ５４を挟み込んで固定することで、天井パネル５３１の、鉄道車両５０の高さ方向の位置を調整し、隣接する天井パネル５３１相互間の高さを一致させている。 However, since the ceiling panel 531 has variations in shape (variations in dimensions, slight twists, etc.) due to shrinkage after molding, when the ceiling panel 531 is directly connected to the fixing member 524, it is described above. Due to the variation in shape and slight twisting, the heights of the adjacent ceiling panels 531 do not match each other and a step is generated, which may spoil the aesthetic appearance of the guest room 53. Therefore, by sandwiching and fixing the spacer 54 made of hard vinyl chloride between the connecting member 535 and the fixing member 524, the position of the ceiling panel 531 in the height direction of the railroad vehicle 50 is adjusted, and the adjacent ceiling panel 531 is used. The heights of each other are matched.

特許第５７５９７１２号公報Japanese Patent No. 5759712

しかしながら、上記従来技術には次のような問題があった。
上述するように、複数配設される天井パネル５３１のそれぞれは、成形後の収縮等により形状にばらつきがある。そのため、隣接する天井パネル５３１相互間で高さ方向の位置を合わせるためには、天井パネル５３１の結合部材５３５を固定部材５２４に取り付けるごとに、作業者が隣接する天井パネル５３１との位置関係を見ながら、様々な厚みのスペーサ５４を試し、天井パネル５３１の高さ方向の位置の微調整を行う必要がある。 However, the above-mentioned prior art has the following problems.
As described above, each of the plurality of ceiling panels 531 arranged has variations in shape due to shrinkage after molding and the like. Therefore, in order to align the positions in the height direction between the adjacent ceiling panels 531 each time, each time the connecting member 535 of the ceiling panel 531 is attached to the fixing member 524, the operator changes the positional relationship with the adjacent ceiling panel 531. While looking at it, it is necessary to try spacers 54 of various thicknesses and fine-tune the position of the ceiling panel 531 in the height direction.

天井パネル５３１の取り付け作業は、美観を損ねていないかどうかを確認するために、一度天井パネル５３１を取り付けた後、離れた位置から天井パネル５３１を観察し、美観に問題がないか確認を行うなど、時間のかかる作業である。そのため、上記したように様々な厚みのスペーサ５４を試して高さ方向の位置の微調整を行うことは、作業効率を余計に低下させるものである。よって、作業効率の向上が望まれている。 In the installation work of the ceiling panel 531, in order to confirm whether or not the aesthetic appearance is spoiled, once the ceiling panel 531 is attached, the ceiling panel 531 is observed from a distant position and the aesthetic appearance is confirmed. It is a time-consuming task. Therefore, as described above, trying spacers 54 of various thicknesses and finely adjusting the position in the height direction further lowers the work efficiency. Therefore, improvement in work efficiency is desired.

作業効率向上のためには、特許文献１に開示される鉄道車両の内装品取付構造を利用することが考えられる（以下の特許文献１に関する説明においては、特に図示をしないが、特許文献１で用いられている符号を用いて説明する）。当該内装品取付構造は、屋根構体４に取り付けられる第１取付部材５と、車両内装品を取り付け可能な第２取付部材６とを備えている。第１取付部材５は、上下方向に延在する長穴５ｄを有しているため、第２取付部材６は、貫通穴を貫通するボルト等の固定具により第１取付部材５に対して上下方向に位置調整可能に取り付けることができる。このため、隣接して配設される複数の第２取付部材６の高さを、容易に一致させることができる。そして、高さを一致させた第２取付部材６に対して車両内装品を取り付ければ、車両内装品を見栄えよく取り付けることができる。 In order to improve work efficiency, it is conceivable to use the interior component mounting structure of the railway vehicle disclosed in Patent Document 1 (in the following description of Patent Document 1, although not particularly shown, Patent Document 1 It will be explained using the code used). The interior component mounting structure includes a first mounting member 5 to be mounted on the roof structure 4 and a second mounting member 6 to which a vehicle interior component can be mounted. Since the first mounting member 5 has an elongated hole 5d extending in the vertical direction, the second mounting member 6 is moved up and down with respect to the first mounting member 5 by a fixing tool such as a bolt penetrating the through hole. It can be mounted so that it can be adjusted in position in the direction. Therefore, the heights of the plurality of second mounting members 6 arranged adjacent to each other can be easily matched. Then, if the vehicle interior parts are attached to the second mounting member 6 having the same height, the vehicle interior parts can be attached in a good-looking manner.

しかし、上記内装品取付構造は、内装品自体の形状のばらつきが考慮されていない点が問題である。例えば、隣接する第２取付部材６のそれぞれに、車両内装品として天井パネルを取り付けたとした場合、第２取付部材６の高さが一致していたとしても、天井パネル自体の形状にばらつきがあるため、隣接する天井パネル相互間で高さ方向の位置が一致せず、段差が生じてしまうおそれがある。そうすると、客室の美観を損ねるおそれがある。 However, the problem with the interior product mounting structure is that variations in the shape of the interior product itself are not taken into consideration. For example, when a ceiling panel is attached to each of the adjacent second mounting members 6 as a vehicle interior component, the shape of the ceiling panel itself varies even if the heights of the second mounting members 6 are the same. Therefore, the positions in the height direction do not match between the adjacent ceiling panels, and there is a possibility that a step may occur. Doing so may spoil the aesthetics of the guest room.

本発明は、上記問題点を解決するためのものであり、天井パネルの取り付け時における高さ方向の位置調整を容易に行うことができ、客室の美観を保つことができる鉄道車両を提供することを目的とする。 The present invention is for solving the above-mentioned problems, and provides a railroad vehicle capable of easily adjusting the position in the height direction at the time of mounting the ceiling panel and maintaining the aesthetic appearance of the passenger cabin. With the goal.

上記課題を解決するために、本発明の鉄道車両は次のような構成を有している。
（１）屋根構体と、屋根構体に結合された固定部材と、固定部材を介して屋根構体に結合され、隣接して軌道方向に並ぶ少なくとも２枚の天井パネルと、を備える鉄道車両において、固定部材は、鉄道車両の高さ方向に延在する第１垂直部を備えること、天井パネルは、固定部材と結合する結合部材を備えること、結合部材は、第１垂直部と平行な第２垂直部を備えること、第１垂直部と第２垂直部のいずれか一方の垂直部は、高さ方向に長手方向を有する貫通長孔を備えること、貫通長孔に挿通されるとともに、他方の垂直部に結合される固定具によって、固定部材に対する結合部材の高さ方向の位置を、貫通長孔の長手方向の長さの範囲内で、任意に調整可能であること、固定部材は、第１垂直部の高さ方向の下端部に、第１垂直部に対して直角に接続された第１水平部を備えること、結合部材は、第２垂直部に接続された、第１水平部と平行な第２水平部を備えること、第１水平部と第２水平部とが第２固定具により結合されること、を特徴とする。 In order to solve the above problems, the railway vehicle of the present invention has the following configuration.
(1) Fixed in a railroad vehicle including a roof structure, a fixing member connected to the roof structure, and at least two ceiling panels connected to the roof structure via the fixing member and adjacent to each other in the track direction. The member comprises a first vertical portion extending in the height direction of the railroad vehicle, the ceiling panel comprises a coupling member to be coupled to the fixing member, and the coupling member is a second vertical portion parallel to the first vertical portion. A portion is provided, one of the vertical portions of the first vertical portion and the second vertical portion is provided with a through hole having a longitudinal direction in the height direction, and is inserted into the through hole and is vertically connected to the other. The position of the connecting member in the height direction with respect to the fixing member can be arbitrarily adjusted within the range of the length in the longitudinal direction of the through hole by the fixing tool connected to the portion. The lower end of the vertical portion in the height direction is provided with a first horizontal portion connected at right angles to the first vertical portion, and the connecting member is parallel to the first horizontal portion connected to the second vertical portion. It is characterized in that a second horizontal portion is provided, and the first horizontal portion and the second horizontal portion are connected by a second fixing tool .

（１）に記載の鉄道車両によれば、固定部材の第１垂直部、または、結合部材の第２垂直部のいずれか一方の垂直部が、高さ方向に長手方向を有する貫通長孔を備えており、貫通長孔に挿通されるとともに、他方の垂直部に結合される固定具によって、固定部材に対する結合部材の高さ方向の位置を、貫通長孔の長手方向の長さの範囲内で、任意に調整可能である。これは、天井パネル自身が結合部材を備えているため、天井パネルの高さ方向の位置を、貫通長孔の長手方向の長さの範囲内で、任意に調整可能であることを意味する。天井パネルの高さ方向の位置を、任意に調整可能であれば、天井パネルに形状のばらつきがあっても、隣接する天井パネル相互間の高さ方向の位置を一致させて固定するため、天井パネルの取り付けを行う際に、作業者が隣接する天井パネルとの位置関係を見ながら高さ方向の位置が一致した位置で固定すれば良いのであり、従来のように様々な厚みのスペーサを試しながら天井パネルの高さ方向の位置の微調整を行う必要がない。よって、天井パネルの取り付け時における高さ方向の位置調整を容易に行うことができ、煩雑な調整作業を行うことなく客室の美観を保つことができる。
また、天井パネルには、吊り手棒や灯具等の内装品が取り付けられるため、固定部材と結合部材との結合によって、天井パネルの質量の他、内装品の質量を支えなければならない。しかし、第１垂直部と第２垂直部との結合によって、これらの質量を支えようとすると、第１垂直部および第２垂直部に対して平行な方向に荷重がかかるため、第１垂直部と第２垂直部との摩擦力によって質量を支えなければならなくなる。この摩擦力のみでは、天井パネルや内装品の質量を十分に支えることが出来ないおそれがある。そこで、（１）に記載の鉄道車両のように、第１水平部と第２水平部とを、固定具により結合することで、天井パネルの固定をより強固なものとすれば、天井パネルや内装品の質量を十分に支えることが可能となる。 According to the railroad vehicle according to (1), the vertical portion of either the first vertical portion of the fixing member or the second vertical portion of the connecting member has a through elongated hole having a longitudinal direction in the height direction. By means of a fixture that is inserted through the through hole and coupled to the other vertical portion, the height position of the coupling member with respect to the fixing member is within the longitudinal length of the through hole. And it can be adjusted arbitrarily. This means that since the ceiling panel itself is provided with a coupling member, the height position of the ceiling panel can be arbitrarily adjusted within the longitudinal length of the through hole. If the position of the ceiling panel in the height direction can be adjusted arbitrarily, even if the shape of the ceiling panel varies, the position in the height direction between adjacent ceiling panels can be matched and fixed. When installing the panel, the operator should fix it at a position where the positions in the height direction match while observing the positional relationship with the adjacent ceiling panel, and try spacers of various thicknesses as in the past. However, there is no need to fine-tune the position of the ceiling panel in the height direction. Therefore, the position in the height direction can be easily adjusted when the ceiling panel is attached, and the aesthetic appearance of the guest room can be maintained without performing complicated adjustment work.
Further, since interior parts such as hanging straps and lamps are attached to the ceiling panel, the mass of the interior parts as well as the mass of the ceiling panel must be supported by the coupling between the fixing member and the connecting member. However, if an attempt is made to support these masses by the coupling between the first vertical portion and the second vertical portion, a load is applied in a direction parallel to the first vertical portion and the second vertical portion, so that the first vertical portion The mass must be supported by the frictional force between the force and the second vertical portion. This frictional force alone may not be sufficient to support the mass of ceiling panels and interior parts. Therefore, as in the case of the railway vehicle described in (1), if the first horizontal portion and the second horizontal portion are connected by a fixing tool to strengthen the fixing of the ceiling panel, the ceiling panel or the like can be used. It is possible to sufficiently support the mass of interior products.

（２）（１）に記載の鉄道車両において、天井パネルは、枕木方向の両端部のそれぞれに、軌道方向に所定の間隔を持って並んだ、少なくとも２つの結合部材を備えること、屋根構体には、それぞれの結合部材に対応する位置に固定部材が設けられており、別個に高さ方向の位置を調整可能であること、を特徴とする。なお、所定の間隔とは、結合部材が、天井パネルの軌道方向の両端部に位置するような間隔を指す。 (2) In the railroad vehicle according to (1), the ceiling panel is provided with at least two connecting members arranged at predetermined intervals in the track direction at both ends in the sleeper direction, and the roof structure. Is characterized in that a fixing member is provided at a position corresponding to each connecting member, and the position in the height direction can be adjusted separately. The predetermined spacing refers to a spacing such that the connecting members are located at both ends of the ceiling panel in the track direction.

（２）に記載の鉄道車両によれば、結合部材が、天井パネルの枕木方向の両端部に位置しているため、結合部材と固定部材とを結合する作業を、作業者の手の届く範囲で行うことができ、天井パネルの取り付け作業が容易となる。また、例えば、天井パネルの上面視において、四角に結合部材を配置して、それぞれ別個に高さ方向の位置を調整可能であれば、天井パネルに捻じれが生じていても、捻じれに合わせてそれぞれの結合部材の高さ方向の位置を調整すれば、隣接する天井パネル相互間で段差を生じさせずに、天井パネルを取り付けることが可能となる。 According to the railroad vehicle described in (2), since the connecting members are located at both ends of the ceiling panel in the sleeper direction, the work of joining the connecting member and the fixing member is within the reach of the operator. It can be done with, and the installation work of the ceiling panel becomes easy. Further, for example, in the top view of the ceiling panel, if the connecting members are arranged in a square and the positions in the height direction can be adjusted individually, even if the ceiling panel is twisted, it is adjusted to the twist. By adjusting the position of each connecting member in the height direction, it is possible to attach the ceiling panel without causing a step between adjacent ceiling panels.

天井パネルには、吊り手棒や灯具等の内装品が取り付けられるため、固定部材と結合部材との結合によって、天井パネルの質量の他、内装品の質量を支えなければならない。しかし、第１垂直部と第２垂直部との結合によって、これらの質量を支えようとすると、第１垂直部および第２垂直部に対して平行な方向に荷重がかかるため、第１垂直部と第２垂直部との摩擦力によって質量を支えなければならなくなる。この摩擦力のみでは、天井パネルや内装品の質量を十分に支えることが出来ないおそれがある。そこで、（３）に記載の鉄道車両のように、第１水平部と第２水平部とを、固定具により結合することで、天井パネルの固定をより強固なものとすれば、天井パネルや内装品の質量を十分に支えることが可能となる。 Since interior parts such as hanging straps and lamps are attached to the ceiling panel, the mass of the interior parts as well as the mass of the ceiling panel must be supported by the connection between the fixing member and the connecting member. However, if an attempt is made to support these masses by the coupling between the first vertical portion and the second vertical portion, a load is applied in a direction parallel to the first vertical portion and the second vertical portion, so that the first vertical portion The mass must be supported by the frictional force between the and the second vertical portion. This frictional force alone may not be sufficient to support the mass of ceiling panels and interior parts. Therefore, as in the case of the railway vehicle described in (3), if the first horizontal portion and the second horizontal portion are connected by a fixing tool to strengthen the fixing of the ceiling panel, the ceiling panel or the like can be used. It is possible to sufficiently support the mass of interior products.

本発明の鉄道車両によれば、天井パネルの取り付け時における高さ方向の位置調整を容易に行うことができ、客室の美観を保つことができる。 According to the railroad vehicle of the present invention, the position in the height direction can be easily adjusted when the ceiling panel is attached, and the aesthetic appearance of the passenger cabin can be maintained.

The U-shaped member 262 includes a first vertical portion 262a extending in the height direction of the railroad vehicle 1 (hereinafter, simply referred to as the height direction). The first vertical portion 262a is provided with two through elongated holes 262b having a longitudinal direction in the height direction side by side in the orbital direction.

さらに、Ｕ字部材２６２は、第１垂直部２６２ａの高さ方向の下端部に、第１垂直部２６２ａに対して直角に接続された第１水平部２６２ｃを備えている。第１水平部２６２ｃには、高さ方向に第１水平部２６２ｃを貫通する貫通ねじ穴２６２ｄが設けられている。該貫通ねじ穴２６２ｄは、第１水平部２６２ｃの枕木方向の両端部のそれぞれに、軌道方向に２つ並んで設けられている。つまり、１つのＵ字部材２６２につき、４つの貫通ねじ穴２６２ｄが設けられている。 Further, the U-shaped member 262 includes a first horizontal portion 262c connected at a right angle to the first vertical portion 262a at the lower end portion of the first vertical portion 262a in the height direction. The first horizontal portion 262c is provided with a through screw hole 262d that penetrates the first horizontal portion 262c in the height direction. Two through-screw holes 262d are provided side by side in the track direction at both ends of the first horizontal portion 262c in the sleeper direction. That is, four through-screw holes 262d are provided for one U-shaped member 262.

天井パネル３１は、軌道方向の長さが約２ｍであり、１両あたり、軌道方向に約１０枚並んで配設されている。また、天井パネル３１は、固定部材２４と結合する結合部材３５を備えている。該結合部材３５は、天井パネル３１の枕木方向の両端部のそれぞれに、軌道方向に約１．５ｍの間隔を持って、２つ並んで配設され、それぞれが断面Ｌ字状のアングル３６により、天井パネル３１と一体にされている。つまり１枚の天井パネル３１ごとに４つの結合部材３５を備えている。なお、アングル３６には、後述するボルト４４を挿通するための貫通孔３６ａが設けられている。 The ceiling panels 31 have a length of about 2 m in the track direction, and about 10 ceiling panels 31 are arranged side by side in the track direction for each car. Further, the ceiling panel 31 includes a connecting member 35 that is coupled to the fixing member 24. Two of the connecting members 35 are arranged side by side at both ends of the ceiling panel 31 in the sleeper direction with an interval of about 1.5 m in the track direction, and each is arranged by an angle 36 having an L-shaped cross section. , Is integrated with the ceiling panel 31. That is, each ceiling panel 31 is provided with four connecting members 35. The angle 36 is provided with a through hole 36a for inserting a bolt 44, which will be described later.

結合部材３５は、例えばステンレス鋼や、アルミ合金からなり、プレス加工またはロストワックス鋳造により製造される。また、結合部材３５は、固定部材２４の第１垂直部２６２ａに平行な第２垂直部３５ａを備え、該第２垂直部３５ａの鉄道車両１の高さ方向の下端部に、固定部材２４の第１水平部２６２ｃと平行な第２水平部３５ｃが接続されることにより、断面Ｌ字状に形成されている。 The bonding member 35 is made of, for example, stainless steel or an aluminum alloy, and is manufactured by stamping or lost wax casting. Further, the coupling member 35 includes a second vertical portion 35a parallel to the first vertical portion 262a of the fixing member 24, and the fixing member 24 is provided at the lower end portion of the second vertical portion 35a in the height direction of the railway vehicle 1. By connecting the second horizontal portion 35c parallel to the first horizontal portion 262c, the cross section is formed in an L shape.

結合部材３５の第２垂直部３５ａには、枕木方向に第２垂直部３５ａを貫通する貫通ねじ穴３５ｂが、軌道方向に２つ並んで設けられている。該貫通ねじ穴３５ｂの軌道方向の位置は、固定部材２４の第１垂直部２６２ａに設けられている貫通長孔２６２ｂの位置に合わせたものとなっている。よって、貫通長孔２６２ｂに挿通されたボルト（固定具の一例）３７を、貫通ねじ穴３５ｂに螺合することができる。この螺合により、第１垂直部２６２ａがボルト３７の頭部と第２垂直部３５ａとに挟まれる。そして、その挟まれたことによる摩擦力によって、固定部材２４に対する結合部材３５の高さ方向の位置（以下、単に固定位置という）が固定される。また、貫通長孔２６２ｂは高さ方向に長手方向を有するものであるため、貫通長孔２６２ｂの長手方向の長さの範囲内で、固定位置を任意に調整可能である。これは、天井パネル３１の高さ方向の位置を、貫通長孔２６２ｂの長手方向の長さの範囲内で、任意に調整可能であることを意味する。天井パネル３１と結合部材３５が一体となっているためである。 The second vertical portion 35a of the coupling member 35 is provided with two through-screw holes 35b penetrating the second vertical portion 35a in the sleeper direction side by side in the track direction. The position of the through screw hole 35b in the track direction is aligned with the position of the through elongated hole 262b provided in the first vertical portion 262a of the fixing member 24. Therefore, the bolt (an example of the fixture) 37 inserted through the through elongated hole 262b can be screwed into the through screw hole 35b. By this screwing, the first vertical portion 262a is sandwiched between the head of the bolt 37 and the second vertical portion 35a. Then, the position of the connecting member 35 in the height direction with respect to the fixing member 24 (hereinafter, simply referred to as a fixing position) is fixed by the frictional force due to the pinching. Further, since the through elongated hole 262b has a longitudinal direction in the height direction, the fixed position can be arbitrarily adjusted within the range of the longitudinal length of the through elongated hole 262b. This means that the height position of the ceiling panel 31 can be arbitrarily adjusted within the longitudinal length of the through slot 262b. This is because the ceiling panel 31 and the connecting member 35 are integrated.

結合部材３５の第２水平部３５ｃには、第２水平部３５ｃを高さ方向に貫通する貫通孔３５ｄが設けられている。該貫通孔３５ｄは、第２水平部３５ｃの枕木方向の両端部のそれぞれに、軌道方向に２つ並んで設けられており、その位置は、固定部材２４の第１水平部２６２ｃに設けられた貫通ねじ穴２６２ｄと同心になるように位置されている。さらに、第２水平部３５ｃの枕木方向の両端部のうち、天井パネル３１側の方の端部に設けられた貫通孔３５ｄは、アングル３６の貫通孔３６ａと同心になるように位置されている。そして、他方の端部に設けられた貫通孔３５ｄは、後述する側天井パネル３２の結合片３２１に設けられた貫通孔３２１ａと同心になるように位置されている。 The second horizontal portion 35c of the coupling member 35 is provided with a through hole 35d that penetrates the second horizontal portion 35c in the height direction. Two through holes 35d are provided side by side in the track direction at both ends of the second horizontal portion 35c in the sleeper direction, and the positions thereof are provided in the first horizontal portion 262c of the fixing member 24. It is positioned so as to be concentric with the through screw hole 262d. Further, among both ends of the second horizontal portion 35c in the sleeper direction, the through hole 35d provided at the end toward the ceiling panel 31 side is positioned so as to be concentric with the through hole 36a of the angle 36. .. The through hole 35d provided at the other end is positioned so as to be concentric with the through hole 321a provided in the connecting piece 321 of the side ceiling panel 32, which will be described later.

側天井パネル３２は、枕木方向の両端部の内、鉄道車両１の外側の方の端部は、側構体２２に結合されている。なお、当該端部が結合されるのは、屋根構体２３であっても良い。そして、他方の端部には、鉤状の断面を有する結合片３２１を備えており、該結合片３２１の上端部は、結合部材３５の第２水平部３５ｃと、後述するブラケット３８のベース体３８１とに挟まれるようにして固定される。 The side ceiling panel 32 has both ends in the direction of the sleepers, and the outer ends of the railroad vehicle 1 are connected to the side structure 22. The roof structure 23 may be connected to the end portions. The other end is provided with a coupling piece 321 having a hook-shaped cross section, and the upper end portion of the coupling piece 321 is a second horizontal portion 35c of the coupling member 35 and a base body of a bracket 38 described later. It is fixed so as to be sandwiched between 381 and 381.

ブラケット３８は、直方体状のベース体３８１を備えており、該ベース体３８１には、ベース体３８１を高さ方向に貫通するボルト受け孔３８１ａが設けられている。そして、ボルト受け孔３８１ａに挿通されたボルト（第２固定具の一例）４４が、結合部材３５の第２水平部３５ｃに設けられた貫通孔３５ｄを通り、固定部材２４の第１水平部２６２ｃに設けられた貫通ねじ穴２６２ｄに螺合されている。このボルト４４の螺合は、ブラケット３８の固定を行うとともに、天井パネル３１の固定を、より強固なものとしている。また、側天井パネル３２の結合片３２１の上端部が、ベース体３８１と結合部材３５の第２水平部３５ｃとにより挟持されることで、側天井パネル３２の固定も行われる。 The bracket 38 includes a rectangular parallelepiped base body 381, and the base body 381 is provided with a bolt receiving hole 381a that penetrates the base body 381 in the height direction. Then, the bolt (an example of the second fixture) 44 inserted into the bolt receiving hole 381a passes through the through hole 35d provided in the second horizontal portion 35c of the coupling member 35, and the first horizontal portion 262c of the fixing member 24. It is screwed into the through screw hole 262d provided in. The screwing of the bolt 44 fixes the bracket 38 and strengthens the fixing of the ceiling panel 31. Further, the side ceiling panel 32 is also fixed by sandwiching the upper end portion of the coupling piece 321 of the side ceiling panel 32 between the base body 381 and the second horizontal portion 35c of the coupling member 35.

また、第１水平部２６２ｃと第２水平部３５ｃとの隙間には、スペーサ２９が挟まれている。このスペーサ２９は、硬質塩ビを平板状に形成したものであり、第１水平部２６２ｃと第２水平部３５ｃとの隙間とほぼ同一の厚みを有している。第１水平部２６２ｃと第２水平部３５ｃとの隙間に、スペーサ２９が挟まれていることで、ボルト４４の締め付けによって結合部材３５の第２水平部３５ｃが、第２垂直部３５ａと接続されている箇所を支点として、撓んでしまうことを防止している。 Further, a spacer 29 is sandwiched between the first horizontal portion 262c and the second horizontal portion 35c. The spacer 29 is formed by forming a hard vinyl chloride into a flat plate shape, and has substantially the same thickness as the gap between the first horizontal portion 262c and the second horizontal portion 35c. Since the spacer 29 is sandwiched between the first horizontal portion 262c and the second horizontal portion 35c, the second horizontal portion 35c of the coupling member 35 is connected to the second vertical portion 35a by tightening the bolt 44. The fulcrum is used as a fulcrum to prevent bending.

（天井パネルの固定方法について）
次に、上記構成を有する鉄道車両１における天井パネル３１の固定方法を、図４を用いて説明する。図４は、天井パネル３１を固定するための工程を説明する図である。 (How to fix the ceiling panel)
Next, a method of fixing the ceiling panel 31 in the railway vehicle 1 having the above configuration will be described with reference to FIG. FIG. 4 is a diagram illustrating a process for fixing the ceiling panel 31.

まず、図４（Ａ）に示すように、固定部材２４を構成する波板部材２５を屋根構体２３に溶接により結合する。この結合の際には、予め凹部２５１，２５２にはボルト２７を挿入しておく。 First, as shown in FIG. 4A, the corrugated sheet member 25 constituting the fixing member 24 is joined to the roof structure 23 by welding. At the time of this connection, bolts 27 are inserted into the recesses 251,252 in advance.

次に、図４（Ｂ）に示すように、ボルト２７とナット２８の螺合させることで、波板部材２５に箱型部材２６を結合させる。箱型部材２６は、軌道方向両端部が開放されているため、当該開放されている端部からスパナ等の工具を箱型部材２６の中に挿し込み、ナット２８を回転させることで、ボルト２７とナット２８の螺合を行うことができる。 Next, as shown in FIG. 4B, the box-shaped member 26 is coupled to the corrugated plate member 25 by screwing the bolt 27 and the nut 28. Since both ends of the box-shaped member 26 are open in the raceway direction, a tool such as a spanner is inserted into the box-shaped member 26 from the opened ends, and the nut 28 is rotated to rotate the bolt 27. And the nut 28 can be screwed.

次に、図４（Ｃ）に示すように、天井パネル３１の高さ方向の位置決めを行う。１枚の天井パネル３１につき、４つの結合部材３５を備えるため、全ての結合部材３５の第２垂直部３５ａのそれぞれが、固定部材２４の第１垂直部２６２ａに第２垂直部３５ａが対向するよう、天井パネル３１を位置させる。そして、第１垂直部２６２ａの内周面側から、貫通長孔２６２ｂにボルト３７を挿通させ、該ボルト３７を第２垂直部３５ａの貫通ねじ穴３５ｂに螺合させる。このときの螺合は、まずは、結合部材３５が、貫通長孔２６２ｂに沿って上下させることができる程度に締め付けるものである。これにより、天井パネル３１の高さ方向の位置を、貫通長孔２６２ｂの長手方向の長さの範囲内で、任意に調整可能となるため、軌道方向に隣接する天井パネル３１と、高さ方向の位置が一致するように、結合部材３５の固定位置を定める。結合部材３５の固定位置を定めた後、ボルト３７をさらに締め付けて、結合部材３５の固定位置がずれないように固定する。ボルト３７の螺合も、箱型部材２６の開放されている軌道方向の端部から、スパナ等の工具を箱型部材２６の中に挿し込んで行う。なお、天井パネル３１は、成形後の収縮等による形状のばらつきを有するため、隣接する天井パネル３１同士の高さ方向の位置を一致させるために、複数ある結合部材３５の固定位置は、それぞれ異なることが想定される。 Next, as shown in FIG. 4C, the ceiling panel 31 is positioned in the height direction. Since one ceiling panel 31 includes four connecting members 35, each of the second vertical portions 35a of all the connecting members 35 faces the first vertical portion 262a of the fixing member 24 with the second vertical portion 35a. The ceiling panel 31 is positioned so as to be. Then, a bolt 37 is inserted into the through elongated hole 262b from the inner peripheral surface side of the first vertical portion 262a, and the bolt 37 is screwed into the through screw hole 35b of the second vertical portion 35a. At this time, the screwing is first tightened to the extent that the connecting member 35 can be moved up and down along the through elongated hole 262b. As a result, the position in the height direction of the ceiling panel 31 can be arbitrarily adjusted within the range of the length in the longitudinal direction of the through slot 262b, so that the ceiling panel 31 adjacent to the track direction and the height direction can be arbitrarily adjusted. The fixed position of the connecting member 35 is determined so that the positions of the joint members 35 match. After determining the fixing position of the connecting member 35, the bolt 37 is further tightened to fix the connecting member 35 so that the fixing position does not shift. The bolt 37 is also screwed by inserting a tool such as a spanner into the box-shaped member 26 from the open end of the box-shaped member 26 in the raceway direction. Since the ceiling panel 31 has a variation in shape due to shrinkage after molding, the fixing positions of the plurality of connecting members 35 are different in order to match the positions of the adjacent ceiling panels 31 in the height direction. Is assumed.

次に、側天井パネル３２の取り付けを行う。まず、側天井パネル３２の、枕木方向の両端部の内、鉄道車両１の外側の方の端部を、側構体２２に結合する。そして、結合片３２１を、結合部材３５の第２水平部３５ｃに接するように位置させるとともに、結合片３２１に設けられた貫通孔３２１ａが、結合部材３５の貫通孔３５ｄと同心になるように位置させる。 Next, the side ceiling panel 32 is attached. First, the outer ends of the railroad vehicle 1 among both ends of the side ceiling panel 32 in the sleeper direction are connected to the side structure 22. Then, the coupling piece 321 is positioned so as to be in contact with the second horizontal portion 35c of the coupling member 35, and the through hole 321a provided in the coupling piece 321 is positioned so as to be concentric with the through hole 35d of the coupling member 35. Let me.

次に、図４（Ｄ）に示すように、ブラケット３８および灯具４１の取り付けを、以下のようにして行う。
まず、第１水平部２６２ｃと第２水平部３５ｃとの隙間を測定する。そして、結合部材３５の第２水平部３５ｃとの隙間に、当該隙間とほぼ同一の厚みを有するスペーサ２９を挟み込む。当該隙間の測定は、ボルト３７の螺合により、固定部材２４に対する結合部材３５の固定位置が定められているため容易である。よって、従来のように様々な厚みのスペーサを試しながら天井パネルの高さ方向の位置の微調整を行う必要がない。
次に、ブラケット３８のベース体３８１に設けられたボルト受け孔３８１ａの位置が、アングル３６の貫通孔３６ａ，側天井パネル３２の結合片３２１に設けられた貫通孔３２１ａの位置に一致するように、ブラケット３８を位置させる。
最後に、ボルト４４を、ボルト受け孔３８１ａおよび貫通孔３５ｄに挿通させ、固定部材２４の第１水平部２６２ｃに設けられた貫通ねじ穴２６２ｄに螺合させる。 Next, as shown in FIG. 4D, the bracket 38 and the lamp 41 are attached as follows.
First, the gap between the first horizontal portion 262c and the second horizontal portion 35c is measured. Then, a spacer 29 having substantially the same thickness as the gap is sandwiched in the gap between the coupling member 35 and the second horizontal portion 35c. The measurement of the gap is easy because the fixing position of the connecting member 35 with respect to the fixing member 24 is determined by screwing the bolt 37. Therefore, it is not necessary to fine-tune the position of the ceiling panel in the height direction while trying spacers of various thicknesses as in the conventional case.
Next, the position of the bolt receiving hole 381a provided in the base body 381 of the bracket 38 coincides with the position of the through hole 36a of the angle 36 and the through hole 321a provided in the connecting piece 321 of the side ceiling panel 32. , Position the bracket 38.
Finally, the bolt 44 is inserted into the bolt receiving hole 381a and the through hole 35d and screwed into the through screw hole 262d provided in the first horizontal portion 262c of the fixing member 24.

（第１の変形例について）
固定部材および結合部材の、第１の変形例について、図５を用いて説明する。図５は、固定部材および結合部材の変形例を表す図であり、図２に対応する図である。 (About the first modification)
A first modification of the fixing member and the connecting member will be described with reference to FIG. FIG. 5 is a diagram showing a modified example of the fixing member and the connecting member, and is a diagram corresponding to FIG. 2.

固定部材４５は、波板部材２５と、断面Ｉ字状のＩ型部材４６と、からなる。波板部材２５は、上記した実施形態のものと同一である。波板部材２５の凹部２５１，２５２のそれぞれにはボルト２７が挿入され、該ボルト２７とナット２８によって、Ｉ型部材４６が波板部材２５に結合されている。 The fixing member 45 includes a corrugated plate member 25 and an I-shaped member 46 having an I-shaped cross section. The corrugated sheet member 25 is the same as that of the above-described embodiment. Bolts 27 are inserted into each of the recesses 251, 252 of the corrugated sheet member 25, and the I-shaped member 46 is coupled to the corrugated sheet member 25 by the bolt 27 and the nut 28.

Ｉ型部材４６は、例えばステンレス鋼や、アルミ合金からなり、プレス加工またはロストワックス鋳造によって形成される。Ｉ型部材４６は、波板部材２５に接続されている上端部から、高さ方向に延在する第１垂直部４６ａを備える。第１垂直部４６ａには、枕木方向に第１垂直部４６ａを貫通する貫通ねじ穴４６ｂが、軌道方向に２つ並んで設けられている。 The I-shaped member 46 is made of, for example, stainless steel or an aluminum alloy, and is formed by press working or lost wax casting. The I-shaped member 46 includes a first vertical portion 46a extending in the height direction from the upper end portion connected to the corrugated plate member 25. The first vertical portion 46a is provided with two through-screw holes 46b penetrating the first vertical portion 46a in the sleeper direction side by side in the track direction.

さらに、Ｉ型部材４６は、第１垂直部４６ａの高さ方向の下端部に、第１垂直部４６ａに対して直角に接続された第１水平部４６ｃを備えている。第１水平部４６ｃには、高さ方向に第１水平部４６ｃを貫通する貫通ねじ穴４６ｄが設けられている。該貫通ねじ穴４６ｄは、第１水平部４６ｃの枕木方向の両端部のそれぞれに、軌道方向に２つ並んで設けられている。つまり、１つのＩ型部材４６につき、４つの貫通ねじ穴４６ｄが設けられている。また、第１水平部４６ｃには、後述する結合部材４７の第２垂直部４７ａを挿通するための、挿通孔４６ｅが高さ方向に貫通している。 Further, the I-shaped member 46 includes a first horizontal portion 46c connected at a right angle to the first vertical portion 46a at the lower end portion of the first vertical portion 46a in the height direction. The first horizontal portion 46c is provided with a through screw hole 46d that penetrates the first horizontal portion 46c in the height direction. Two through-screw holes 46d are provided side by side in the track direction at both ends of the first horizontal portion 46c in the sleeper direction. That is, four through-screw holes 46d are provided for one I-shaped member 46. Further, the insertion hole 46e for inserting the second vertical portion 47a of the coupling member 47, which will be described later, penetrates the first horizontal portion 46c in the height direction.

天井パネル３１には、アングル３６により、結合部材４７が一体とされている。結合部材４７は、例えばステンレス鋼や、アルミ合金からなり、プレス加工またはロストワックス鋳造により製造される。また、結合部材４７は、固定部材４５の第１水平部４６ｃと平行な、第２水平部４７ｃを有している。第２水平部４７ｃの枕木方向の中央部には、第１垂直部４６ａに平行な第２垂直部４７ａが突設されている。第２垂直部４７ａは、固定部材４５の下方から挿通孔４６ｅに、挿通され、第１垂直部４６ａの枕木方向の端面のうち、鉄道車両内側の端面に接触するようにして位置されている。 A connecting member 47 is integrated with the ceiling panel 31 by an angle 36. The bonding member 47 is made of, for example, stainless steel or an aluminum alloy, and is manufactured by stamping or lost wax casting. Further, the connecting member 47 has a second horizontal portion 47c parallel to the first horizontal portion 46c of the fixing member 45. A second vertical portion 47a parallel to the first vertical portion 46a is projected from the central portion of the second horizontal portion 47c in the direction of the sleepers. The second vertical portion 47a is inserted into the insertion hole 46e from below the fixing member 45, and is positioned so as to come into contact with the inner end surface of the railroad vehicle among the end faces of the first vertical portion 46a in the sleeper direction.

結合部材４７の第２垂直部４７ａには、高さ方向に長手方向を有する貫通長孔４７ｂが、軌道方向に２つ並んで設けられている。該貫通長孔４７ｂの軌道方向の位置は、固定部材４５の第１垂直部４６ａに設けられている貫通ねじ穴４６ｂの位置に合わせたものとなっている。よって、貫通長孔４７ｂに挿通されたボルト３７を、貫通ねじ穴４６ｂに螺合することができる。この螺合により、第２垂直部４７ａがボルト３７の頭部と第１垂直部４６ａとに挟まれる。そして、その挟まれたことによる摩擦力によって、固定部材４５に対する結合部材４７の固定位置が固定される。また、貫通長孔４７ｂは高さ方向に長手方向を有するものであるため、貫通長孔４７ｂの長手方向の長さの範囲内で、固定位置を任意に調整可能である。これは、天井パネル３１の高さ方向の位置を、貫通長孔４７ｂの長手方向の長さの範囲内で、任意に調整可能であることを意味する。天井パネル３１と結合部材４７が一体となっているためである。 The second vertical portion 47a of the coupling member 47 is provided with two through elongated holes 47b having a longitudinal direction in the height direction side by side in the orbital direction. The position of the through elongated hole 47b in the orbit direction is aligned with the position of the through screw hole 46b provided in the first vertical portion 46a of the fixing member 45. Therefore, the bolt 37 inserted through the long through hole 47b can be screwed into the through screw hole 46b. By this screwing, the second vertical portion 47a is sandwiched between the head of the bolt 37 and the first vertical portion 46a. Then, the fixed position of the connecting member 47 with respect to the fixing member 45 is fixed by the frictional force caused by the pinching. Further, since the through-long hole 47b has a longitudinal direction in the height direction, the fixed position can be arbitrarily adjusted within the range of the length of the through-long hole 47b in the longitudinal direction. This means that the height position of the ceiling panel 31 can be arbitrarily adjusted within the longitudinal length of the through slot 47b. This is because the ceiling panel 31 and the connecting member 47 are integrated.

結合部材４７の第２水平部４７ｃには、第２水平部４７ｃを高さ方向に貫通する貫通孔４７ｄが設けられている。該貫通孔４７ｄは、第２水平部４７ｃの枕木方向の両端部のそれぞれに、軌道方向に２つ並んで設けられており、その位置は、固定部材４５の第１水平部４６ｃに設けられた貫通ねじ穴４６ｄと同心になるように位置されている。さらに、第２水平部４７ｃの枕木方向の両端部のうち、天井パネル３１側の方の端部に設けられた貫通孔４７ｄは、アングル３６の貫通孔３６ａと同心になるように位置されている。そして、他方の端部に設けられた貫通孔４７ｄは、側天井パネル３２の結合片３２１に設けられた貫通孔３２１ａと同心になるように位置されている。 The second horizontal portion 47c of the coupling member 47 is provided with a through hole 47d that penetrates the second horizontal portion 47c in the height direction. Two through holes 47d are provided side by side in the track direction at both ends of the second horizontal portion 47c in the sleeper direction, and the positions thereof are provided in the first horizontal portion 46c of the fixing member 45. It is positioned so as to be concentric with the through screw hole 46d. Further, among both ends of the second horizontal portion 47c in the sleeper direction, the through hole 47d provided at the end on the ceiling panel 31 side is positioned so as to be concentric with the through hole 36a of the angle 36. .. The through hole 47d provided at the other end is positioned so as to be concentric with the through hole 321a provided in the connecting piece 321 of the side ceiling panel 32.

ブラケット３８は、上記した実施形態のものと同一である。ベース体３８１に設けられたボルト受け孔３８１ａに挿通されたボルト４４が、結合部材４７の第２水平部４７ｃに設けられた貫通孔４７ｄを通り、固定部材４５の第１水平部４６ｃに設けられた貫通ねじ穴４６ｄに螺合されている。このボルト４４の螺合は、ブラケット３８の固定を行うとともに、天井パネル３１の固定を、より強固なものとしている。また、側天井パネル３２の結合片３２１の上端部が、ベース体３８１と結合部材４７の第２水平部４７ｃとにより挟持されることで、側天井パネル３２の固定も行われる。 The bracket 38 is the same as that of the above-described embodiment. The bolt 44 inserted into the bolt receiving hole 381a provided in the base body 381 passes through the through hole 47d provided in the second horizontal portion 47c of the coupling member 47, and is provided in the first horizontal portion 46c of the fixing member 45. It is screwed into the through screw hole 46d. The screwing of the bolt 44 fixes the bracket 38 and strengthens the fixing of the ceiling panel 31. Further, the side ceiling panel 32 is also fixed by sandwiching the upper end portion of the coupling piece 321 of the side ceiling panel 32 between the base body 381 and the second horizontal portion 47c of the coupling member 47.

また、第１水平部４６ｃと第２水平部４７ｃとの隙間には、スペーサ２９が挟まれている。このスペーサ２９は、硬質塩ビを平板状に形成したものであり、第１水平部４６ｃと第２水平部４７ｃとの隙間とほぼ同一の厚みを有している。第１水平部４６ｃと第２水平部４７ｃとの隙間に、スペーサ２９が挟まれていることで、ボルト４４の締め付けによって結合部材４７の第２水平部４７ｃが、第２垂直部４７ａと接続されている箇所を支点として、撓んでしまうことを防止している。 Further, a spacer 29 is sandwiched between the first horizontal portion 46c and the second horizontal portion 47c. The spacer 29 is formed by forming hard vinyl chloride into a flat plate shape, and has substantially the same thickness as the gap between the first horizontal portion 46c and the second horizontal portion 47c. Since the spacer 29 is sandwiched between the first horizontal portion 46c and the second horizontal portion 47c, the second horizontal portion 47c of the coupling member 47 is connected to the second vertical portion 47a by tightening the bolt 44. It is prevented from bending by using the point where it is as a fulcrum.

（第２の変形例について）
固定部材および結合部材の、第２の変形例について、図６を用いて説明する。図６は、固定部材および結合部材の変形例を表す図であり、図２に対応する図である。 (About the second modification)
A second modification of the fixing member and the connecting member will be described with reference to FIG. FIG. 6 is a diagram showing a modified example of the fixing member and the connecting member, and is a diagram corresponding to FIG. 2.

固定部材６１は、波板部材２５と、断面Ｕ字状のＵ型部材６２と、からなる。波板部材２５は、上記した実施形態のものと同一である。波板部材２５の凹部２５１，２５２のそれぞれにはボルト２７が挿入され、該ボルト２７とナット２８によって、Ｕ型部材６２が波板部材２５に結合されている。 The fixing member 61 includes a corrugated plate member 25 and a U-shaped member 62 having a U-shaped cross section. The corrugated sheet member 25 is the same as that of the above-described embodiment. Bolts 27 are inserted into each of the recesses 251, 252 of the corrugated sheet member 25, and the U-shaped member 62 is connected to the corrugated sheet member 25 by the bolts 27 and the nuts 28.

Ｕ型部材６２は、例えばステンレス鋼や、アルミ合金からなり、プレス加工またはロストワックス鋳造によって形成される。Ｕ型部材６２は、波板部材２５に接続されている上端部から、高さ方向に延在する一対の第１垂直部６２ａを備える。一対の第１垂直部６２ａの内、天井パネル３１側の第１垂直部６２ａには、枕木方向に第１垂直部６２ａを貫通する貫通ねじ穴６２ｂが、軌道方向に２つ並んで設けられている。他方の第１垂直部６２ａには、枕木方向に第１垂直部６２ａを貫通する貫通孔６２ｃが、軌道方向に２つ並んで設けられている。 The U-shaped member 62 is made of, for example, stainless steel or an aluminum alloy, and is formed by press working or lost wax casting. The U-shaped member 62 includes a pair of first vertical portions 62a extending in the height direction from the upper end portion connected to the corrugated plate member 25. Of the pair of first vertical portions 62a, the first vertical portion 62a on the ceiling panel 31 side is provided with two through screw holes 62b penetrating the first vertical portion 62a in the sleeper direction side by side in the track direction. There is. The other first vertical portion 62a is provided with two through holes 62c penetrating the first vertical portion 62a in the sleeper direction side by side in the orbital direction.

天井パネル３１には、アングル３６により、結合部材６３が一体とされている。結合部材６３は、例えばステンレス鋼や、アルミ合金からなり、プレス加工またはロストワックス鋳造により、断面Ｕ字状に形成されている。結合部材６３には、下端部６３ｄの枕木方向の両端部から高さ方向に延在し、第１垂直部６２ａに平行な、一対の第２垂直部６３ａが設けられている。第２垂直部６３ａは、Ｕ型部材６２の開放されている下方から、Ｕ型部材６２に組付けられ、第１垂直部６２ａの内壁に接触するようにして位置されている。 A connecting member 63 is integrated with the ceiling panel 31 by an angle 36. The bonding member 63 is made of, for example, stainless steel or an aluminum alloy, and is formed into a U-shaped cross section by press working or lost wax casting. The connecting member 63 is provided with a pair of second vertical portions 63a extending in the height direction from both ends of the lower end portion 63d in the sleeper direction and parallel to the first vertical portion 62a. The second vertical portion 63a is assembled to the U-shaped member 62 from the open lower side of the U-shaped member 62, and is positioned so as to be in contact with the inner wall of the first vertical portion 62a.

結合部材６３の、一対の第２垂直部６３ａのそれぞれには、高さ方向に長手方向を有する貫通長孔６３ｂが、軌道方向に２つ並んで設けられている。該貫通長孔６３ｂの軌道方向の位置は、固定部材６１の第１垂直部６２ａに設けられている貫通ねじ穴６２ｂおよび貫通孔６２ｃの位置に合わせたものとなっている。よって、貫通孔６２ｃから挿通され、貫通長孔６３ｂを通ったボルト６４を、貫通ねじ穴６２ｂに螺合することができる。この螺合により、結合部材６３が、一対の第１垂直部６２ａに挟まれる。そして、その挟まれたことによる摩擦力によって、固定部材６１に対する結合部材６３の固定位置が固定される。また、貫通長孔６３ｂは高さ方向に長手方向を有するものであるため、貫通長孔６３ｂの長手方向の長さの範囲内で、固定位置を任意に調整可能である。これは、天井パネル３１の高さ方向の位置を、貫通長孔６３ｂの長手方向の長さの範囲内で、任意に調整可能であることを意味する。天井パネル３１と結合部材６３が一体となっているためである。 Each of the pair of second vertical portions 63a of the coupling member 63 is provided with two through elongated holes 63b having a longitudinal direction in the height direction side by side in the orbital direction. The positions of the through elongated holes 63b in the orbit direction are aligned with the positions of the through screw holes 62b and the through holes 62c provided in the first vertical portion 62a of the fixing member 61. Therefore, the bolt 64 that is inserted through the through hole 62c and passes through the through long hole 63b can be screwed into the through screw hole 62b. By this screwing, the coupling member 63 is sandwiched between the pair of first vertical portions 62a. Then, the fixed position of the coupling member 63 with respect to the fixing member 61 is fixed by the frictional force caused by the pinching. Further, since the through elongated hole 63b has a longitudinal direction in the height direction, the fixed position can be arbitrarily adjusted within the range of the longitudinal length of the through elongated hole 63b. This means that the height position of the ceiling panel 31 can be arbitrarily adjusted within the longitudinal length of the through slot 63b. This is because the ceiling panel 31 and the connecting member 63 are integrated.

結合部材６３の下端部６３ｄには、下端部６３ｄを高さ方向に貫通する貫通ねじ穴６３ｃが設けられている。該貫通ねじ穴６３ｃは、下端部６３ｄの枕木方向の両端部のそれぞれに、軌道方向に２つ並んで設けられている。その位置は、下端部６３ｄの枕木方向の両端部のうち、天井パネル３１側の方の端部に設けられた貫通ねじ穴６３ｃは、アングル３６の貫通孔３６ａと同心になるように位置されている。そして、他方の端部に設けられた貫通ねじ穴６３ｃは、側天井パネル３２の結合片３２１に設けられた貫通孔３２１ａと同心になるように位置されている。 The lower end portion 63d of the coupling member 63 is provided with a through screw hole 63c that penetrates the lower end portion 63d in the height direction. Two through-screw holes 63c are provided side by side in the track direction at both ends of the lower end 63d in the sleeper direction. The position is such that the through screw hole 63c provided at the end on the ceiling panel 31 side of both ends of the lower end 63d in the sleeper direction is concentric with the through hole 36a of the angle 36. There is. The through screw hole 63c provided at the other end is positioned so as to be concentric with the through hole 321a provided in the connecting piece 321 of the side ceiling panel 32.

ブラケット３８は、上記した実施形態のものと同一である。ベース体３８１に設けられたボルト受け孔３８１ａに挿通されたボルト４４が、結合部材６３の下端部６３ｄに設けられた貫通ねじ穴６３ｃに螺合されている。このボルト４４の螺合により、ブラケット３８の固定を行っている。また、側天井パネル３２の結合片３２１の上端部が、ベース体３８１と結合部材６３の下端部６３ｄとにより挟持されることで、側天井パネル３２の固定も行われる。 The bracket 38 is the same as that of the above-described embodiment. The bolt 44 inserted into the bolt receiving hole 381a provided in the base body 381 is screwed into the through screw hole 63c provided in the lower end portion 63d of the coupling member 63. The bracket 38 is fixed by screwing the bolt 44. Further, the side ceiling panel 32 is also fixed by sandwiching the upper end portion of the coupling piece 321 of the side ceiling panel 32 between the base body 381 and the lower end portion 63d of the coupling member 63.

以上説明したように、本実施形態に係る鉄道車両１によれば、
（１）屋根構体２３と、屋根構体２３に結合された固定部材２４，４５，６１と、固定部材２４，４５，６１を介して屋根構体２３に結合され、隣接して軌道方向に並ぶ少なくとも２枚の天井パネル３１と、を備える鉄道車両１において、固定部材２４，４５，６１は、鉄道車両１の高さ方向に延在する第１垂直部２６２ａ，４６ａ，６２ａを備えること、天井パネル３１は、固定部材２４，４５，６１と結合する結合部材３５，４７，６３を備えること、結合部材３５，４７，６３は、第１垂直部２６２ａ，４６ａ，６２ａと平行な第２垂直部３５ａ，４７ａ，６３ａを備えること、第１垂直部２６２ａ，４６ａ，６２ａと第２垂直部３５ａ，４７ａ，６３ａのいずれか一方の垂直部は、高さ方向に長手方向を有する貫通長孔２６２ｂ，４７ｂ，６３ｂを備えること、貫通長孔２６２ｂ，４７ｂ，６３ｂに挿通されるとともに、他方の垂直部に結合される固定具（ボルト３７，６４）によって、固定部材２４，４５，６１に対する結合部材３５，４７，６３の高さ方向の位置を、貫通長孔２６２ｂ，４７ｂ，６３ｂの長手方向の長さの範囲内で、任意に調整可能であること、を特徴とする。 As described above, according to the railway vehicle 1 according to the present embodiment,
(1) At least 2 which are connected to the roof structure 23 via the roof structure 23, the fixing members 24, 45, 61 connected to the roof structure 23, and the fixing members 24, 45, 61, and are adjacent to each other in the orbital direction. In the railroad vehicle 1 including the ceiling panel 31, the fixing members 24, 45, 61 include first vertical portions 262a, 46a, 62a extending in the height direction of the railroad vehicle 1, the ceiling panel 31. Provides coupling members 35, 47, 63 to be coupled to the fixing members 24, 45, 61, wherein the coupling members 35, 47, 63 are second vertical portions 35a, parallel to the first vertical portions 262a, 46a, 62a. 47a, 63a is provided, and one of the first vertical portions 262a, 46a, 62a and the second vertical portions 35a, 47a, 63a has a through elongated hole 262b, 47b, which has a longitudinal direction in the height direction. With 63b, the coupling members 35, 47 to the fixing members 24, 45, 61 by the fixtures (bolts 37, 64) that are inserted into the through elongated holes 262b, 47b, 63b and are coupled to the other vertical portion. , 63 is characterized in that the position in the height direction can be arbitrarily adjusted within the range of the length in the longitudinal direction of the through elongated holes 262b, 47b, 63b.

（１）に記載の鉄道車両１によれば、固定部材２４，４５，６１の第１垂直部２６２ａ，４６ａ，６２ａ、または、結合部材３５，４７，６３の第２垂直部３５ａ，４７ａ，６３ａのいずれか一方の垂直部が、高さ方向に長手方向を有する貫通長孔２６２ｂ，４７ｂ，６３ｂを備えており、貫通長孔２６２ｂ，４７ｂ，６３ｂに挿通されるとともに、他方の垂直部に結合される固定具（ボルト３７，６４）によって、固定部材２４，４５，６１に対する結合部材３５，４７，６３の高さ方向の位置を、貫通長孔２６２ｂ，４７ｂ，６３ｂの長手方向の長さの範囲内で、任意に調整可能である。これは、天井パネル３１自身が結合部材３５，４７，６３を備えているため、天井パネル３１の高さ方向の位置を、貫通長孔２６２ｂ，４７ｂ，６３ｂの長手方向の長さの範囲内で、任意に調整可能であることを意味する。天井パネル３１の高さ方向の位置を、任意に調整可能であれば、天井パネル３１に形状のばらつきがあっても、隣接する天井パネル３１相互間の高さ方向の位置を一致して固定するためには、天井パネル３１の取り付けを行う際に、作業者が隣接する天井パネル３１との位置関係を見ながら高さ方向の位置が一致した位置で固定すれば良いのであり、従来のように様々な厚みのスペーサ５４を試しながら天井パネル３１の高さ方向の位置の微調整を行う必要がない。よって、天井パネル３１の取り付け時における高さ方向の位置調整を容易に行うことができ、煩雑な調整作業を行うことなく客室３の美観を保つことができる。 According to the railway vehicle 1 according to (1), the first vertical portions 262a, 46a, 62a of the fixing members 24, 45, 61, or the second vertical portions 35a, 47a, 63a of the connecting members 35, 47, 63. One of the vertical portions thereof has through elongated holes 262b, 47b, 63b having a longitudinal direction in the height direction, is inserted through the through elongated holes 262b, 47b, 63b, and is coupled to the other vertical portion. By the fixing tool (bolt 37, 64), the position of the connecting member 35, 47, 63 with respect to the fixing member 24, 45, 61 in the height direction is set to the length of the through elongated holes 262b, 47b, 63b in the longitudinal direction. It can be adjusted arbitrarily within the range. This is because the ceiling panel 31 itself includes the coupling members 35, 47, 63, so that the position of the ceiling panel 31 in the height direction is within the range of the length of the through elongated holes 262b, 47b, 63b in the longitudinal direction. , Means that it can be adjusted arbitrarily. If the position in the height direction of the ceiling panel 31 can be arbitrarily adjusted, even if the shape of the ceiling panel 31 varies, the position in the height direction between the adjacent ceiling panels 31 is fixed to be the same. For this purpose, when the ceiling panel 31 is attached, the operator may fix the ceiling panel 31 at a position where the positions in the height direction match while observing the positional relationship with the adjacent ceiling panel 31. It is not necessary to fine-tune the position of the ceiling panel 31 in the height direction while trying spacers 54 of various thicknesses. Therefore, the position in the height direction can be easily adjusted when the ceiling panel 31 is attached, and the aesthetic appearance of the guest room 3 can be maintained without performing complicated adjustment work.

（２）（１）に記載の鉄道車両１において、天井パネル３１は、枕木方向の両端部のそれぞれに、軌道方向に所定の間隔を持って並んだ、少なくとも２つの結合部材３５，４７，６３を備えること、屋根構体２３には、それぞれの結合部材３５，４７，６３に対応する位置に固定部材２４，４５，６１が設けられており、別個に高さ方向の位置を調整可能であること、を特徴とする。なお、所定の間隔とは、結合部材３５，４７，６３が、天井パネル３１の軌道方向の両端部に位置するような間隔を指す。天井パネル３１の軌道方向の長さが２ｍ程度であれば、約１．５ｍの間隔をもって配置される。 (2) In the railway vehicle 1 according to (1), the ceiling panel 31 has at least two connecting members 35, 47, 63 arranged at both ends in the sleeper direction at predetermined intervals in the track direction. The roof structure 23 is provided with fixing members 24, 45, 61 at positions corresponding to the respective connecting members 35, 47, 63, and the positions in the height direction can be adjusted separately. , Is characterized. The predetermined interval means an interval in which the connecting members 35, 47, 63 are located at both ends of the ceiling panel 31 in the orbit direction. If the length of the ceiling panel 31 in the track direction is about 2 m, the ceiling panels 31 are arranged at intervals of about 1.5 m.

（２）に記載の鉄道車両１によれば、結合部材３５，４７，６３が、天井パネル３１の枕木方向の両端部に位置しているため、結合部材３５，４７，６３と固定部材２４，４５，６１とを結合する作業を、作業者の手の届く範囲で行うことができ、天井パネル３１の取り付け作業が容易となる。また、例えば、天井パネル３１の上面視において、四角に結合部材３５，４７，６３を配置して、それぞれ別個に高さ方向の位置を調整可能であれば、天井パネル３１に捻じれが生じていても、捻じれに合わせてそれぞれの結合部材３５，４７，６３の高さ方向の位置を調整すれば、隣接する天井パネル３１相互間で段差を生じさせずに、天井パネル３１を取り付けることが可能となる。 According to the railway vehicle 1 described in (2), since the connecting members 35, 47, 63 are located at both ends of the ceiling panel 31 in the sleeper direction, the connecting members 35, 47, 63 and the fixing member 24, The work of connecting the 45 and 61 can be performed within the reach of the operator, and the work of attaching the ceiling panel 31 becomes easy. Further, for example, in the top view of the ceiling panel 31, if the connecting members 35, 47, 63 are arranged in a square and the positions in the height direction can be adjusted separately, the ceiling panel 31 is twisted. However, if the positions of the respective connecting members 35, 47, 63 in the height direction are adjusted according to the twist, the ceiling panel 31 can be attached without causing a step between the adjacent ceiling panels 31. It will be possible.

（３）（１）または（２）に記載の鉄道車両１において、固定部材２４，４５は、第１垂直部２６２ａ，４６ａの高さ方向の下端部に、第１垂直部２６２ａ，４６ａに対して直角に接続された第１水平部２６２ｃ，４６ｃを備えること、結合部材３５，４７は、第２垂直部３５ａ，４７ａに接続された、第１水平部２６２ｃ，４６ｃと平行な第２水平部３５ｃ，４７ｃを備えること、第１水平部２６２ｃ，４６ｃと第２水平部３５ｃ，４７ｃとが第２固定具（ボルト４４）により結合されること、を特徴とする。 (3) In the railway vehicle 1 according to (1) or (2), the fixing members 24, 45 are attached to the lower ends of the first vertical portions 262a, 46a in the height direction with respect to the first vertical portions 262a, 46a. The first horizontal portions 262c and 46c are connected at right angles to each other, and the connecting members 35 and 47 are connected to the second vertical portions 35a and 47a and are parallel to the first horizontal portions 262c and 46c. It is characterized by including 35c and 47c, and the first horizontal portions 262c and 46c and the second horizontal portions 35c and 47c are connected by a second fixture (bolt 44).

天井パネル３１には、吊り手棒３９や灯具４１等の内装品が取り付けられるため、固定部材２４，４５と結合部材３５，４７との結合によって、天井パネル３１の質量の他、内装品の質量を支えなければならない。しかし、第１垂直部２６２ａ，４６ａと第２垂直部３５ａ，４７ａとの結合によって、これらの質量を支えようとすると、第１垂直部２６２ａ，４６ａおよび第２垂直部３５ａ，４７ａに対して平行な方向に荷重がかかるため、第１垂直部２６２ａ，４６ａと第２垂直部３５ａ，４７ａとの摩擦力によって質量を支えなければならなくなる。この摩擦力のみでは、天井パネル３１や内装品の質量を十分に支えることが出来ないおそれがある。そこで、（３）に記載の鉄道車両１のように、第１水平部２６２ｃ，４６ｃと第２水平部３５ｃ，４７ｃとを、固定具により結合することで、天井パネル３１の固定をより強固なものとすれば、天井パネル３１や内装品の質量を十分に支えることが可能となる。 Since interior parts such as hanging straps 39 and lighting fixtures 41 are attached to the ceiling panel 31, the mass of the interior parts as well as the mass of the ceiling panel 31 due to the connection between the fixing members 24 and 45 and the connecting members 35 and 47. Must be supported. However, when trying to support these masses by the coupling between the first vertical portions 262a, 46a and the second vertical portions 35a, 47a, they are parallel to the first vertical portions 262a, 46a and the second vertical portions 35a, 47a. Since the load is applied in the above directions, the mass must be supported by the frictional force between the first vertical portions 262a and 46a and the second vertical portions 35a and 47a. This frictional force alone may not be sufficient to support the mass of the ceiling panel 31 and interior parts. Therefore, as in the railway vehicle 1 described in (3), the ceiling panel 31 is more firmly fixed by connecting the first horizontal portions 262c and 46c and the second horizontal portions 35c and 47c with a fixing tool. If so, it is possible to sufficiently support the mass of the ceiling panel 31 and the interior parts.

なお、上記の実施形態は単なる例示にすぎず、本発明を何ら限定するものではない。したがって本発明は当然に、その要旨を逸脱しない範囲内で様々な改良、変形が可能である。例えば、側天井パネル３２は、ブラケット３８のベース体３８１と、結合部材３５，４７の第２水平部３５ｃ，４７ｃまたは結合部材６３の下端部６３ｄとにより、結合片３２１が挟持されることで固定されることとしているが、結合片３２１を、結合部材３５，４７，６３に、ボルト等により結合する構造としても良い。 It should be noted that the above embodiment is merely an example and does not limit the present invention in any way. Therefore, the present invention can be variously improved and modified without departing from the gist of the present invention. For example, the side ceiling panel 32 is fixed by sandwiching the coupling piece 321 by the base body 381 of the bracket 38 and the second horizontal portions 35c, 47c of the coupling members 35, 47 or the lower end portion 63d of the coupling member 63. However, the structure may be such that the connecting piece 321 is connected to the connecting members 35, 47, 63 by a bolt or the like.
