Description

本発明は、鉄道車両の内部のユニット室の壁に形成された開口部を開閉するための折り戸に関する。   The present invention relates to a folding door for opening and closing an opening formed in a wall of a unit room inside a railway vehicle.

鉄道車両には、その内部に小便所用のトイレユニット室が設けられたものがある。室内空間が限られるため、このトイレユニット室のために十分なスペースを確保するのが難しくなり、特に車両サイズが小さい場合には、トイレユニット室は狭小になることが多い。そのため、小便所用のトイレユニット室のドアには、開閉動作時の使用スペースが少なくて済む折り戸が用いられることがある。例えば、特許文献１の折り戸には、室外側から折り戸を開けるための室外用引き手と、室内側から折り戸を開けるための室内用引き手とが設けられている。この折り戸では、室内用引き手が室内空間に向けて突出するため、鉄道車両に適用するとトイレユニット室の室内空間が狭くなるとともに、車両走行中の揺れにより室内の使用者の体が室内用引き手に当たるなどの不便があった。   Some railcars have a toilet unit room for a urinal inside. Since the indoor space is limited, it is difficult to secure a sufficient space for the toilet unit room. In particular, when the vehicle size is small, the toilet unit room is often narrowed. Therefore, folding doors that require less space for opening and closing operations may be used for the toilet unit room doors for urinals. For example, the folding door of Patent Document 1 is provided with an outdoor puller for opening the folding door from the outdoor side and an indoor puller for opening the folding door from the indoor side. In this folding door, the indoor puller protrudes toward the indoor space. Therefore, when applied to a railway vehicle, the indoor space of the toilet unit room becomes narrower, and the body of the user in the room is moved indoors by shaking while the vehicle is running. There was inconvenience such as hitting a puller.

そこで、鉄道車両の内部の小便器用のトイレユニット室に設けた折り戸には、室内用引き手を設けずに、折り戸の室内面の所定箇所に平坦な押し板を目印として取り付け、室内の使用者が押し板を手で室外側に向けて押すことで折り戸を開けるようにしたものがある。これによれば、押し板が引き手のように室内空間に突出しないため、室内空間が狭くならないとともに、車両走行中の揺れにより室内の使用者の体が動いても使用者の邪魔にもならない。   Therefore, the folding door provided in the toilet unit room for the urinal inside the railway vehicle is provided with a flat push plate as a mark at a predetermined position on the indoor surface of the folding door without providing a puller for the room. There is one in which the user opens the folding door by pushing the push plate toward the outdoor side by hand. According to this, since the push plate does not protrude into the indoor space like a pulling hand, the indoor space is not narrowed, and it does not disturb the user even if the body of the user moves due to shaking while the vehicle is running. .

しかしながら、室内面に押し板を設けた折り戸では、室内の使用者が折り戸を押し開く際に、その押す箇所によっては容易に開かない場合がある。また、押し開く際に、意外と力が要り、非力な使用者とっては開けにくい場合があった。   However, in a folding door provided with a push plate on the indoor surface, when a user in the room pushes and opens the folding door, it may not be easily opened depending on the pushing position. Moreover, when pushing and opening, unexpected force is required, and it may be difficult for a weak user to open.

そこで本発明は、使用者が室内側から容易に押し開くことのできる鉄道車両用折り戸を提供することを目的とする。   Then, an object of this invention is to provide the folding door for rail vehicles which a user can push open easily from the indoor side.

本発明に係る鉄道車両用折り戸は、鉄道車両の内部のユニット室の壁に形成され、上端または下端に案内部材を有する開口部を開閉するための折り戸であって、前記開口部の周縁の一側に回動可能に一端部が接続される第１パネルと、前記第１パネルの他側に配置され、上端または下端に前記案内部材により案内される被案内部材を有し、前記被案内部材を中心に回動可能な第２パネルと、前記第１パネルの他端部に前記第２パネルの一端部を回動可能に連結する折り畳み用ヒンジと、前記第２パネルのうち前記被案内部材の軸線よりも他端部寄りの室内面に設けられ、室内の使用者が前記折り戸を押し開くための押し部と、を備え、前記押し部は、前記第２パネルの室内面に対して前記第１パネル側に向けて傾斜した傾斜面を有している。   A railcar folding door according to the present invention is a folding door for opening and closing an opening having a guide member at an upper end or a lower end, which is formed on a wall of a unit chamber inside the railcar, and has a peripheral edge of the opening. A first panel having one end rotatably connected to one side of the first panel, and a guided member disposed on the other side of the first panel and guided by the guide member at an upper end or a lower end. A second panel pivotable about a guide member; a folding hinge for pivotally connecting one end of the second panel to the other end of the first panel; Provided on the indoor surface closer to the other end than the axis of the guide member, and a pusher for a user in the room to push open the folding door, and the pusher is provided on the indoor surface of the second panel. On the other hand, it has an inclined surface inclined toward the first panel side.

前記構成によれば、第２パネルが全閉状態から開き始めるときの第２パネルの厚み方向中心の軌跡の方向は、第２パネルに直交する方向となるが、第２パネルが全閉状態から開き始めるときの第２パネルの室内面の軌跡の方向は、第２パネルに直交する方向から角度をもつことになる。そして、使用者がユニット室の室内側から押し部の傾斜面を押した力は、その傾斜面に直交する方向に作用し、その傾斜面に直交する方向は、第２パネルの室内面に直交する方向から同様に角度をもつこととなる。それゆえ、押し部の傾斜面を押した力は、第２パネルが全閉状態から開き始めるときの押し部の軌跡の方向に作用しやすくなる。したがって、室内側から押して開くタイプの鉄道車両用折り戸において、使用者は室内側から折り戸を容易に開くことができる。   According to the above configuration, the direction of the locus of the center of the thickness direction of the second panel when the second panel starts to open from the fully closed state is a direction orthogonal to the second panel, but the second panel is from the fully closed state. The direction of the locus of the indoor surface of the second panel when starting to open has an angle from the direction orthogonal to the second panel. And the force which the user pushed the inclined surface of the pushing part from the indoor side of the unit room acts in the direction orthogonal to the inclined surface, and the direction orthogonal to the inclined surface is orthogonal to the indoor surface of the second panel. In the same way, it will have an angle from the direction in which it is made. Therefore, the force that pushes the inclined surface of the pushing portion is likely to act in the direction of the locus of the pushing portion when the second panel starts to open from the fully closed state. Therefore, in the type of railcar folding door that is pushed and opened from the indoor side, the user can easily open the folding door from the indoor side.

以上の説明から明らかなように、本発明によれば、使用者が室内側から容易に押し開くことのできる鉄道車両用折り戸を提供することができる。   As is apparent from the above description, according to the present invention, it is possible to provide a railcar folding door that can be easily pushed open by the user from the indoor side.

以下、実施形態を図面を参照して説明する。   Hereinafter, embodiments will be described with reference to the drawings.

（第１実施形態）
図１は、第１実施形態に係る鉄道車両１の折り戸５及びその近傍を示す水平断面図である。図２は、図１に示す折り戸５の室内側から見た図面である。図１及び２に示すように、鉄道車両１の内部には、小便所用のトイレユニット室２が設けられている。そのトイレユニット室２の壁３に形成された開口部４（出入口）には、開口部４を開閉するための折り戸５が取り付けられている。トイレユニット室２の室内には、折り戸５と反対側にて小便器６及び手洗器７が設けられている。 (First embodiment)
FIG. 1 is a horizontal sectional view showing a folding door 5 and its vicinity of a railway vehicle 1 according to the first embodiment. FIG. 2 is a view of the folding door 5 shown in FIG. 1 as viewed from the indoor side. As shown in FIGS. 1 and 2, a toilet unit room 2 for a urinal is provided inside the railway vehicle 1. A folding door 5 for opening and closing the opening 4 is attached to the opening 4 (entrance / exit) formed in the wall 3 of the toilet unit chamber 2. In the room of the toilet unit room 2, a urinal 6 and a hand-washer 7 are provided on the side opposite to the folding door 5.

折り戸５は、第１パネル１１と、窓部１３ａを有する第２パネル１３と、第１パネル１１に対して第２パネル１３を回転自在に連結する折り畳み用ヒンジ１２とを備えている。第２パネル１３の幅Ｗ２は、第１パネル１１の幅Ｗ１よりも大きい。第１パネル１１の一端部１１ａは、開口部４の周縁の一側部８にオートヒンジ１４を介して回動可能にされている。オートヒンジ１４は、折り戸５を全閉状態とする方向に付勢する付勢部材（図示せず）を内蔵した公知のヒンジである。折り畳み用ヒンジ１２は、第１パネル１１の他端部１１ｂと第２パネル１３の一端部１３ｅとを回動自在に連結しており、折り戸５が全閉状態のときに第１パネル１１と第２パネル１３とが同一平面上に並ぶようになっている。   The folding door 5 includes a first panel 11, a second panel 13 having a window portion 13 a, and a folding hinge 12 that rotatably couples the second panel 13 to the first panel 11. The width W2 of the second panel 13 is larger than the width W1 of the first panel 11. One end portion 11 a of the first panel 11 is rotatable on one side portion 8 of the peripheral edge of the opening 4 via an auto hinge 14. The auto hinge 14 is a known hinge that incorporates an urging member (not shown) that urges the folding door 5 in the fully closed state. The folding hinge 12 rotatably connects the other end portion 11b of the first panel 11 and the one end portion 13e of the second panel 13, and when the folding door 5 is fully closed, The second panel 13 is arranged on the same plane.

第２パネル１３の他端部１３ｂ（戸先部）には、その先端に鉛直方向に延びる戸先ゴム１５が取り付けられており、開口部４の周縁の他側部９には、折り戸５の全閉時に戸先ゴム１５に接触する相手ゴム１０が取り付けられている。また、第２パネル１３の上端の幅方向中心には、ガイド用のピン１８（被案内部材）が上方に突出しており、開口部４の上側にはピン１８を案内するガイドレール１９（案内部材）が設けられている。これにより、第２パネル１３が室外方向に押されると、第２パネル１３がピン１８の軸線ＣＬを中心として回転するとともに、ピン１８がガイドレール１９に案内されて、折り戸５が開放されることになる。なお、本実施の形態では、第２パネル１３を案内するための部材として、ピン１８とガイドレール１９を用いているが、これらに限られるものではない。また、ピン１８は、第２パネル１３の上端に設けても良いし、下端あるいは双方に設けても良い。   The other end portion 13 b (door tip portion) of the second panel 13 is attached with a door tip rubber 15 extending in the vertical direction at the tip thereof, and the folding door 5 is attached to the other side portion 9 of the periphery of the opening 4. A mating rubber 10 is attached which contacts the door rubber 15 when fully closed. Further, a guide pin 18 (guided member) projects upward at the center of the upper end of the second panel 13 in the width direction, and a guide rail 19 (guide member) that guides the pin 18 above the opening 4. ) Is provided. Thus, when the second panel 13 is pushed in the outdoor direction, the second panel 13 rotates about the axis CL of the pin 18 and the pin 18 is guided by the guide rail 19 to open the folding door 5. It will be. In the present embodiment, the pins 18 and the guide rails 19 are used as members for guiding the second panel 13, but the present invention is not limited to these. Further, the pin 18 may be provided at the upper end of the second panel 13, or may be provided at the lower end or both.

第２パネル１３の室外面１３ｃの他端部１３ｂ寄りには、室外の使用者が折り戸５を引いて開くための引き手１６が取り付けられている。第２パネル１３の室内面１３ｄの他端部１３ｂ寄りには、室内の使用者が折り戸５を押して開くための押し部として、第２パネル１３とは別体の押し部材１７が取り付けられている。   Near the other end 13b of the outdoor surface 13c of the second panel 13, a pulling handle 16 is attached for an outdoor user to pull and open the folding door 5. Near the other end 13b of the indoor surface 13d of the second panel 13, a pushing member 17 separate from the second panel 13 is attached as a pushing portion for a user in the room to push and open the folding door 5. Yes.

図３は、図１に示す折り戸５の要部の水平断面図である。図３に示すように、押し部材１７は、金属板を曲げ加工して形成されたものである。押し部材１７は、一端部２１ａから他端部２１ｂにいくにつれて第２パネル１３の室内面１３ｄから離れるように鉛直線周りに傾斜して配置された傾斜壁部２１と、その傾斜壁部２１の他端部２１ｂから第２パネル１３に向けて延びる垂直壁部２２とを有している。傾斜壁部２１の室内側の面は、第２パネル１３の室内面１３ｄに対して第１パネル１１側、即ちピン１８の軸線ＣＬ側に向けて傾斜した傾斜面２１ｃである。傾斜面２１ｃは、傾斜壁部２１の一端部２１ａから他端部２１ｂに向けて一定角度で傾斜したテーパ面であり、押し部材１７の上端から下端まで形成されている。本実施形態では、傾斜面２１ｃは、室内側から見た押し部材１７において幅方向の一端部から他端部まで全体的に設けられている。押し部材１７は、例えば、傾斜壁部２１を第２パネル１３内の芯材２３に締結具２４（ネジ等）で固定されている。   FIG. 3 is a horizontal sectional view of an essential part of the folding door 5 shown in FIG. As shown in FIG. 3, the pressing member 17 is formed by bending a metal plate. The pushing member 17 is inclined with respect to the vertical line so as to move away from the indoor surface 13d of the second panel 13 as it goes from the one end 21a to the other end 21b. A vertical wall portion 22 extending from the other end portion 21 b toward the second panel 13. The surface on the indoor side of the inclined wall portion 21 is an inclined surface 21 c inclined toward the first panel 11 side, that is, the axis CL side of the pin 18 with respect to the indoor surface 13 d of the second panel 13. The inclined surface 21 c is a tapered surface that is inclined at a constant angle from the one end 21 a to the other end 21 b of the inclined wall portion 21, and is formed from the upper end to the lower end of the push member 17. In the present embodiment, the inclined surface 21c is entirely provided from one end portion to the other end portion in the width direction in the pressing member 17 viewed from the indoor side. In the pressing member 17, for example, the inclined wall portion 21 is fixed to the core member 23 in the second panel 13 with a fastener 24 (screw or the like).

図４は、図３に示す折り戸５の力学的原理を説明する概念図である。図４に示すように、第２パネル１３が全閉状態から開き始めるときの第２パネル１３の厚み方向中心Ｃの軌跡方向Ｄ１は、第２パネル１３に直交する方向となる。しかし、第２パネル１３が全閉状態から開き始めるときの第２パネル１３の室内面１３ｄの軌跡方向は、第２パネル１３に直交する方向から角度をもつことになる。本実施形態では、テーパ面である傾斜面２１ｃに直交する仮想線Ｌは、第２パネル１３の動作軌跡のうち全閉状態から開き始めるときの傾斜面２１ｃの軌跡方向Ｄ２に向いている。本実施形態では、傾斜面２１ｃに直交する仮想線Ｌは、第２パネル１３の動作軌跡のうち全閉状態から開き始めるときの傾斜面２１ｃの軌跡方向Ｄ２に一致している。   FIG. 4 is a conceptual diagram for explaining the mechanical principle of the folding door 5 shown in FIG. As shown in FIG. 4, the trajectory direction D1 of the center C in the thickness direction of the second panel 13 when the second panel 13 starts to open from the fully closed state is a direction orthogonal to the second panel 13. However, the locus direction of the indoor surface 13d of the second panel 13 when the second panel 13 starts to open from the fully closed state has an angle from the direction orthogonal to the second panel 13. In the present embodiment, the imaginary line L that is orthogonal to the inclined surface 21c, which is a tapered surface, faces the trajectory direction D2 of the inclined surface 21c when starting to open from the fully closed state of the operation locus of the second panel 13. In the present embodiment, the virtual line L orthogonal to the inclined surface 21c coincides with the trajectory direction D2 of the inclined surface 21c when the second panel 13 starts to open from the fully closed state.

そして、使用者がトイレユニット室２の室内側から押し部材１７の傾斜面２１ｃを押した力は、その傾斜面２１ｃに直交する方向（仮想線Ｌ）に作用し、その傾斜面２１ｃに作用する力は、第２パネル１３の動作軌跡のうち全閉状態から開き始めるときの傾斜面２１ｃの軌跡方向Ｄ２に一致することとなる。それゆえ、押し部材１７の傾斜面２１ｃを押した力は、第２パネル１３が全閉状態から開き始めるときの押し部材１７の軌跡方向に十分に作用することとなる。したがって、室内側から押して開くタイプの鉄道車両用折り戸５において、少ない力でも室内側から開けやすくすることが可能となる。   And the force which the user pushed the inclined surface 21c of the pushing member 17 from the indoor side of the toilet unit room 2 acts on the direction (virtual line L) orthogonal to the inclined surface 21c, and acts on the inclined surface 21c. The force coincides with the locus direction D2 of the inclined surface 21c when starting to open from the fully closed state in the operation locus of the second panel 13. Therefore, the force pushing the inclined surface 21c of the push member 17 sufficiently acts in the locus direction of the push member 17 when the second panel 13 starts to open from the fully closed state. Therefore, in the type of railcar folding door 5 that is pushed and opened from the indoor side, it can be easily opened from the indoor side with a small force.

また、第２パネル１３を押して折り戸５を開くにあたっては、第２パネル１３の回動中心であるピン１８の軸線ＣＬから離れたところを押した方が、テコの原理により必要な力が小さくて済む。特に、本実施の形態の折り戸において、ピン１８は第２パネル１３の上端に設けられており、使用者が視覚的に認識することが困難であり、第２パネル１３の回動中心が折り畳み用ヒンジ１２と誤認することがある。かかる場合、使用者がピン１８の軸線ＣＬの近傍を押した場合、押した力は第２パネル１３の回転にほとんど寄与せず、折り戸５を開きにくい状況となる。   Further, when opening the folding door 5 by pushing the second panel 13, the force required to push away from the axis CL of the pin 18, which is the rotation center of the second panel 13, is smaller due to the lever principle. I'll do it. In particular, in the folding door of the present embodiment, the pin 18 is provided at the upper end of the second panel 13 and is difficult for the user to visually recognize, and the rotation center of the second panel 13 is folded. It may be mistaken for the hinge 12 for use. In this case, when the user presses the vicinity of the axis CL of the pin 18, the pressed force hardly contributes to the rotation of the second panel 13, and the folding door 5 is difficult to open.

そこで、本実施の形態では、押し部材１７を設けることにより、第２パネル１３の回動中心からの距離が大きい箇所を使用者が押すように誘導することができる。   Therefore, in the present embodiment, by providing the pressing member 17, it is possible to guide the user to press a location where the distance from the rotation center of the second panel 13 is large.

押し部材１７は、戸先側（戸先ゴム１５側）にいくにつれて第２パネル１３の室内面１３ｄからの突出量が大きくなるので、その視覚的効果から、使用者は押し部材１７の傾斜面２１ｃのうち戸先側を押すように促されることとなる。よって、その観点からも、押し部材１７は、使用者が小さい力で折り戸５を開けることができることに貢献することが可能となる。特に、押し部材１７を第２パネル１３の他端部寄りに設けることにより、使用者が第２パネル１３の回動中心から離れた位置を押すように視覚的に促すことができる。   Since the protrusion amount from the indoor surface 13d of the 2nd panel 13 becomes large as the pressing member 17 goes to the door end side (door end rubber 15 side), the user is inclined surface of the pressing member 17 from the visual effect. It will be prompted to push the door end side of 21c. Therefore, also from that viewpoint, the push member 17 can contribute to the user being able to open the folding door 5 with a small force. In particular, by providing the push member 17 near the other end of the second panel 13, the user can be visually prompted to push a position away from the rotation center of the second panel 13.

図５は、実施例の押し部材１７を押して折り戸を開けることが可能な力を測定した実験結果を示す図面である。図６は、比較例の押し部材９９を押して折り戸を開けることが可能な力を測定した実験結果を示す図面である。図５及び６に示した実施例及び比較例は、同構造の折り戸のうち押し部材１７，９９のみを取り換えて比較実験したものである。実施例の押し部材１７は、上述した実施形態の構造である。比較例の押し部材９９は、平坦な板であり、第２パネルと平行である。   FIG. 5 is a diagram showing an experimental result of measuring a force capable of pushing the push member 17 of the embodiment to open the folding door. FIG. 6 is a drawing showing the experimental results of measuring the force with which the pushing member 99 of the comparative example can be pushed to open the folding door. The examples and comparative examples shown in FIGS. 5 and 6 are comparative experiments in which only the push members 17 and 99 are replaced in the folding door having the same structure. The push member 17 of the example has the structure of the above-described embodiment. The pressing member 99 of the comparative example is a flat plate and is parallel to the second panel.

本実験では、携帯型のプッシュプルゲージを用いて、押し部材１７，９９の所定の押圧箇所を押して、折り戸が開けることができる押し力を測定した。プッシュプルゲージで押し部材１７，９９を押す箇所は、３列５行の計１５箇所とした。その実験の結果、図５及び６に示すように、押し部材１７，９９を押して折り戸を開けることが可能な力は、実施例の押し部材１７の方が、比較例の押し部材９９に比べて７０％ほどに小さくできることが分かった（図５及び６に記載の各数字の単位はＮ）。また、押し部材１７，９９を押して折り戸を開けることが可能な力は、押圧箇所が戸先側にいくにつれて小さくなることも確認された。   In this experiment, using a portable push-pull gauge, the pressing force that can open the folding door was measured by pressing a predetermined pressing portion of the pressing members 17 and 99. The push members 17 and 99 were pushed by a push-pull gauge, and a total of 15 places with 3 columns and 5 rows. As a result of the experiment, as shown in FIGS. 5 and 6, the force that can push the push members 17 and 99 to open the folding door is higher in the push member 17 in the embodiment than in the push member 99 in the comparative example. It was found that the number can be as small as 70% (the unit of each number described in FIGS. 5 and 6 is N). Moreover, it was also confirmed that the force which can push the pushing members 17 and 99 and open a folding door becomes small as a press location goes to the door tip side.

In the present embodiment, the inclined surface 121c is provided from the center portion in the width direction to the other end portion of the pressing member 117 viewed from the indoor side.

使用者が室内側から押し部材１１７の傾斜面１２１ｃを押した力は、その傾斜面１２１ｃに直交する方向に作用し、その傾斜面１２１ｃに作用する力は、第２パネル１３の動作軌跡のうち全閉状態から開き始めるときの傾斜面１２１ｃの軌跡方向に一致することとなる。それゆえ、押し部材１１７の傾斜面１２１ｃを押した力は、第２パネル１３が全閉状態から開き始めるときの押し部材１１７の軌跡方向に作用しやすくなる。したがって、室内側から押して開くタイプの鉄道車両用折り戸１０５において、少ない力でも室内側から開けやすくすることが可能となる。また、第２パネル１３を押して折り戸１０５を開くにあたっては、第２パネル１３の回動中心であるピン１８の軸線ＣＬ（図２参照）から離れたところを押した方が、テコの原理により必要な力が小さくて済む。本実施形態の押し部材１１７は、戸先側に傾斜壁部１２１が設けられているので、その視覚的効果から、使用者は押し部材１１７のうち戸先側を押すように促されることとなる。よって、その観点からも、押し部材１１７は、使用者が小さい力で折り戸１０５を開けることができることに貢献することが可能となる。なお、第１実施形態と共通する構成については同一符号を付して説明を省略する。   The force with which the user pushed the inclined surface 121c of the pushing member 117 from the indoor side acts in a direction orthogonal to the inclined surface 121c, and the force acting on the inclined surface 121c is the movement trajectory of the second panel 13. This coincides with the trajectory direction of the inclined surface 121c when opening from the fully closed state. Therefore, the force pressing the inclined surface 121c of the pressing member 117 is likely to act in the direction of the locus of the pressing member 117 when the second panel 13 starts to open from the fully closed state. Therefore, in the type of railway vehicle folding door 105 that is pushed and opened from the indoor side, it can be easily opened from the indoor side even with a small force. Further, when opening the folding door 105 by pushing the second panel 13, it is better to push away from the axis line CL (see FIG. 2) of the pin 18 which is the rotation center of the second panel 13 in accordance with the lever principle. Less force is required. Since the inclined member 121 is provided on the door tip side of the push member 117 of the present embodiment, the user is prompted to push the door tip side of the push member 117 from the visual effect. . Therefore, also from that viewpoint, the pressing member 117 can contribute to the user being able to open the folding door 105 with a small force. In addition, about the structure which is common in 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 8 is a horizontal cross-sectional view of a main part of the folding door 205 of the railway vehicle according to the third embodiment. As shown in FIG. 8, in the vicinity of the other end portion 13 b of the indoor surface 13 d of the second panel 13, as a pushing portion for a user in the room to push and open the folding door 205, it is separate from the second panel 13. A push member 217 is attached. The pressing member 217 includes a parallel wall portion 220 that is parallel to the indoor surface 13d of the second panel 13, and an arc wall portion 221 that protrudes away from the indoor surface 13d continuously to the other end portion 21b side of the parallel wall portion 220. have. In the pressing member 217, for example, the parallel wall portion 220 is fixed to the core member 23 in the second panel 13 with the fastener 24. Of the surfaces on the indoor side of the arc wall 221, the surface on the parallel wall 220 side is an inclined surface inclined toward the axis CL side (see FIG. 2) of the pin 18 with respect to the indoor surface 13 d of the second panel 13. 221c. The inclined surface 221c is a surface inclined in an arc shape from one end portion of the arc wall portion 221 toward the center portion, and is formed from the upper end to the lower end of the push member 217. In this embodiment, the circular arc wall part 221 is provided from the center part of the width direction to the other end part in the pressing member 217 seen from the indoor side.

使用者が室内側から押し部材２１７の傾斜面２２１ｃを押した力は、その傾斜面２２１ｃに直交する方向に作用し、その傾斜面２２１ｃに作用する力は、第２パネル１３の動作軌跡のうち全閉状態から開き始めるときの傾斜面２２１ｃの軌跡方向に一致することとなる。それゆえ、押し部材２１７の傾斜面２２１ｃを押した力は、第２パネル１３が全閉状態から開き始めるときの押し部材２１７の軌跡方向に作用しやすくなる。したがって、室内側から押して開くタイプの鉄道車両用折り戸２０５において、少ない力でも室内側から開けやすくすることが可能となる。また、第２パネル１３を押して折り戸２０５を開くにあたっては、第２パネル１３の回動中心であるピン１８の軸線ＣＬ（図２参照）から離れたところを押した方が、テコの原理により必要な力が小さくて済む。本実施形態の押し部材２１７は、戸先側に円弧壁部２２１が設けられているので、その視覚的効果から、使用者は押し部材２１７のうち戸先側を押すように促されることとなる。よって、その観点からも、押し部材２１７は、使用者が小さい力で折り戸２０５を開けることができることに貢献することが可能となる。なお、第１実施形態と共通する構成については同一符号を付して説明を省略する。   The force with which the user pushed the inclined surface 221c of the pushing member 217 from the indoor side acts in a direction perpendicular to the inclined surface 221c, and the force acting on the inclined surface 221c is the movement trajectory of the second panel 13. This coincides with the trajectory direction of the inclined surface 221c when opening from the fully closed state. Therefore, the force that pushes the inclined surface 221c of the push member 217 is likely to act in the locus direction of the push member 217 when the second panel 13 starts to open from the fully closed state. Therefore, the railcar folding door 205 of the type that is pushed and opened from the indoor side can be easily opened from the indoor side with a small force. Further, when the second panel 13 is pushed to open the folding door 205, it is preferable to push away from the axis CL (see FIG. 2) of the pin 18 that is the rotation center of the second panel 13 in accordance with the lever principle. Less force is required. Since the push member 217 of the present embodiment is provided with the arc wall portion 221 on the door end side, the visual effect thereof prompts the user to push the door end side of the push member 217. . Therefore, also from that viewpoint, the pressing member 217 can contribute to the user being able to open the folding door 205 with a small force. In addition, about the structure which is common in 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
