Description

本発明は、鉄道車両における引き戸装置に関するものである。   The present invention relates to a sliding door device in a railway vehicle.

鉄道車両やモノレールの軌条車両の引き戸は、車両の側面や、鉄道車両の長手方向の端部の妻部に設けられている。妻部の引き戸は車両と車両を接続する貫通路に設置されている。   Sliding doors for rail vehicles and monorail rail vehicles are provided on the side surfaces of the vehicles and on the end portions of the longitudinal ends of the rail vehicles. The sliding door of the wife part is installed in a through-passage that connects the vehicles.

妻部の引き戸は、重力式の引き戸であり、水平面に対して戸袋側が高くなるように傾斜したレールから吊り下がっており、人間の力で一方に引っ張って開く一方、レールの傾斜による重力で自然に閉まるようになっている。   The sliding door of the wife part is a gravity type sliding door that hangs from a slanted rail so that the door pocket side is higher than the horizontal plane. It is supposed to be closed.

これによれば、引き戸を開閉する電力や、空気圧が不要で、装置を簡単にできる。特に、引き戸が妻出入り口を閉じた後は、動力または人力がないと開放できないので安全である。   According to this, electric power and air pressure for opening and closing the sliding door are unnecessary, and the apparatus can be simplified. In particular, after the sliding door closes the doorway, it is safe because it cannot be opened without power or human power.

このような引き戸は、傾斜したレール上に乗っているので、引き戸の開閉動作に伴って上下動する。このため、引き戸が開放された状態では、戸先側端部の下端と、通路の床面との間に隙間が開く。特に鉄道車両の場合はカントや遠心力があるため、レールの傾斜角度を２度程度とする必要があり、例えば７００ｍｍ可動するドアの場合で、床面と引き戸の下端との間の隙間が２５ｍｍ程度変化する。   Since such a sliding door rides on an inclined rail, it moves up and down with the opening and closing operation of the sliding door. For this reason, in the state where the sliding door is opened, a gap is opened between the lower end of the door end side end and the floor surface of the passage. Particularly in the case of a railway vehicle, there is a cant and centrifugal force, so it is necessary to set the inclination angle of the rail to about 2 degrees. For example, in the case of a door that can move 700 mm, the gap between the floor surface and the lower end of the sliding door is 25 mm. Varies.

このような隙間があると、その隙間に、サンダルなどを履いた乗客の足先が挟まれることがあり、好ましいことではない。特に混雑した際には、乗客が押されて、靴の先端が前記隙間に入り込んでしまう可能性がある。また、物（空缶、電池など）が、前記隙間に入り込み、引き戸が開閉不良になるおそれもある。   If there is such a gap, the foot of a passenger wearing sandals or the like may be caught in the gap, which is not preferable. In particular, when crowded, the passenger may be pushed and the tip of the shoe may enter the gap. Also, there is a possibility that objects (empty cans, batteries, etc.) will enter the gap and the sliding door will be poorly opened and closed.

そこで、水平方向に対して戸袋側が高くなるように傾斜させたレールに沿って移動させて、妻出入り口を開閉させる重力式引き戸において、前記引き戸は水平方向に対して傾斜したレールから吊り下がっており、前記引き戸の引き戸本体の下端部と床面との間の空間を閉鎖する閉鎖板を前記引き戸本体に、前記引き戸の戸尻側のピンで上下方向に回転自在に設置しており、前記閉鎖板の下端は前記レールの傾斜角度と実質的に同一の傾斜角度で傾斜していることによって、引き戸の下端と床面との間の隙間をなくすことが提案されている（例えば特許文献１参照）。
特開２００７−５６４８７号公報（段落００１１〜００１４および図６） Therefore, in the gravity type sliding door that moves along the rail inclined so that the door pocket side becomes higher with respect to the horizontal direction and opens and closes the doorway, the sliding door is suspended from the rail inclined with respect to the horizontal direction. A closing plate for closing a space between the lower end of the sliding door main body and the floor surface of the sliding door is installed in the sliding door main body so as to be freely rotatable in the vertical direction by a pin on the door bottom side of the sliding door. It has been proposed that the lower end of the plate is inclined at substantially the same inclination angle as the rail, thereby eliminating a gap between the lower end of the sliding door and the floor surface (see, for example, Patent Document 1). ).
JP 2007-56487 A (paragraphs 0011 to 0014 and FIG. 6)

前記特許文献１記載の技術では、閉鎖板を本体に、引き戸の戸尻側のピンで上下方向に回転自在に設置し、閉鎖板は戸先側から戸尻側までの幅を必要とするので、重量面で不利である。   In the technique described in Patent Document 1, the closing plate is installed in the main body, and can be freely rotated in the vertical direction by a pin on the door bottom side of the sliding door, and the closing plate requires a width from the door tip side to the door bottom side. It is disadvantageous in terms of weight.

それに加えて、既存の車両にすでに取り付けられている引き戸に、前記特許文献１記載のように閉鎖板を取り付けるには、引き戸をかなり改造する必要があるのに加えて、下のガイド（レール）の幅を狭くするなどの、車両側の改造も必要となる。   In addition, in order to attach a closing plate to a sliding door already attached to an existing vehicle as described in Patent Document 1, it is necessary to considerably modify the sliding door, and the lower guide (rail) It is also necessary to modify the vehicle side, such as reducing the width of the vehicle.

この発明は、重量をあまり増加させることなく、床面と引き戸との隙間に、サンダルなどを履いた乗客の足先が挟まれるのを防止した鉄道車両における引き戸装置を提供することを目的とする。   An object of the present invention is to provide a sliding door device in a railway vehicle that prevents a passenger's feet wearing sandals from being caught in a gap between a floor surface and a sliding door without increasing the weight so much. .

請求項１の発明は、水平方向に対して戸袋側が高くなるように傾斜したレールに引き戸が吊り下げられ、この引き戸が前記レールに沿って移動させることで開閉する鉄道車両における引き戸装置において、前記引き戸の戸先側であって室内側および車外側の下端部それぞれに、板状の閉鎖部材が上下方向に移動自在に支持され、前記閉鎖部材は、引き戸の全開時に戸袋より外側に位置していることを特徴とする。   The invention according to claim 1 is a sliding door device in a railway vehicle in which a sliding door is suspended by a rail inclined so that the door pocket side becomes higher with respect to the horizontal direction, and the sliding door is opened and closed by moving along the rail. A plate-like closing member is supported on the door end side of the sliding door and on the lower side of the indoor side and the outside of the vehicle so as to be movable in the vertical direction, and the closing member is located outside the door pocket when the sliding door is fully opened. It is characterized by being.

このようにすれば、上下方向に移動自在に支持されている閉鎖部材が床面と引き戸との隙間を塞ぐので、床面と引き戸との隙間に、サンダルなどを履いた乗客の足先が挟まれるのを防止することができる。前記閉鎖部材は、引き戸の全開時に戸袋より外側に位置し、前記閉鎖部材を戸先側に設けるだけであるので、重量をあまり増加させることがなく、既存車両の改良に有効である。   In this way, since the closing member supported so as to be movable in the vertical direction closes the gap between the floor surface and the sliding door, the foot of the passenger wearing sandals is sandwiched between the floor surface and the sliding door. Can be prevented. Since the closing member is located outside the door pocket when the sliding door is fully opened and the closing member is only provided on the door end side, the weight does not increase so much and it is effective in improving the existing vehicle.

請求項２に記載のように、前記引き戸または閉鎖部材の一方に上下方向に延びる被係合部が形成され、他方に前記被係合部にスライド可能に係合される係合部材が設けられている構成とすることができる。   According to a second aspect of the present invention, an engaged portion that extends in the vertical direction is formed on one of the sliding door or the closing member, and an engaging member that is slidably engaged with the engaged portion is provided on the other. It can be set as the structure which has.

このようにすれば、被係合部と係合部材との係合関係を利用しているので、閉鎖部材を上下方向において移動自在とすることができる。   In this way, since the engaging relationship between the engaged portion and the engaging member is used, the closing member can be moved in the vertical direction.

請求項３に記載のように、前記被係合部は上下方向に延びる長孔であり、前記係合部材は前記長孔にスライド可能に係合される係合ピン部材であることが望ましい。   Preferably, the engaged portion is a long hole extending in the vertical direction, and the engaging member is an engaging pin member that is slidably engaged with the long hole.

このようにすれば、長孔と係合ピン部材との係合関係を利用しているので、簡単な構造で、閉鎖部材を上下方向において移動自在とすることができる。   In this way, since the engagement relationship between the long hole and the engagement pin member is utilized, the closing member can be moved in the vertical direction with a simple structure.

請求項４に記載のように、前記長孔の位置は、前記車外側の閉鎖部材と前記室内側の閉鎖部材とにおいて、上下方向にずれていることが望ましい。   According to a fourth aspect of the present invention, it is desirable that the position of the long hole is shifted in the vertical direction between the closing member on the vehicle outer side and the closing member on the indoor side.

このようにすれば、長孔の位置が、前記車外側の閉鎖部材と前記室内側の閉鎖部材とにおいて、上下方向にずれているので、前記長孔を設けることによる引き戸の剛性が低下するのが防止される。   In this case, the position of the long hole is shifted in the vertical direction between the closing member on the vehicle exterior side and the closing member on the indoor side, so that the rigidity of the sliding door by providing the long hole is reduced. Is prevented.

請求項５に記載のように、戸袋付近に、引き戸本体の下端開放部分にスライド可能に係合するガイドピンなどのガイド部材が設けられ、前記ガイド部材に取付板が固定されてそれらが一体化され、前記閉鎖部材は、引き戸の全開時に、前記取付板より上方に位置することが望ましい。   As described in claim 5, a guide member such as a guide pin that is slidably engaged with a lower end open portion of the sliding door body is provided in the vicinity of the door pocket, and a mounting plate is fixed to the guide member so that they are integrated. The closing member is preferably positioned above the mounting plate when the sliding door is fully opened.

このようにすれば、ガイド部材による引き戸の振れの防止を確保して、閉鎖部材により乗客の足先が挟まれるのを防止することができる。   If it does in this way, prevention of the swing of the sliding door by a guide member can be secured, and it can prevent that a passenger's foot is pinched by a closure member.

その場合には、請求項６に記載のように、引き戸の開放時には、引き戸が全開になる手前で、前記係合ピン部材は、前記長孔の上端部に位置している構成とすればよい。   In this case, as described in claim 6, when the sliding door is opened, the engagement pin member may be positioned at the upper end of the long hole before the sliding door is fully opened. .

このようにすれば、簡単な構成で、ガイド部材が取り付けられる取付板と閉鎖部材との干渉が回避される。   In this way, with a simple configuration, interference between the mounting plate to which the guide member is attached and the closing member is avoided.

本発明は、上記のように、閉鎖部材が床面と引き戸との隙間を塞ぐので、床面と引き戸との隙間に、サンダルなどを履いた乗客の足先が挟まれるのを防止することができる。戸先側に設けているだけであるので、重量をあまり増加させることがない。   In the present invention, as described above, since the closing member closes the gap between the floor surface and the sliding door, it is possible to prevent a passenger's feet wearing sandals from being caught in the gap between the floor surface and the sliding door. it can. Since it is only provided on the door end side, the weight is not increased so much.

特に、前記閉鎖部材は、引き戸の全開時に戸袋より外側に位置し、前記閉鎖部材を戸先側に設けるだけであるので、重量をあまり増加させることがなく、既存車両の改良に有効である。   In particular, the closing member is positioned outside the door pocket when the sliding door is fully opened, and the closing member is only provided on the door end side, so that the weight is not increased so much and it is effective for improving an existing vehicle.

以下、本発明の実施の形態を図面に沿って説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１（ａ）は本発明の一実施の形態に係る鉄道車両における引き戸装置を示す正面図、図１（ｂ）は同側面図、図２は妻引き戸の開閉動作の説明図、図３は引き戸取付構造を示す正面図、図４は図１（ｂ）におけるＡ部の拡大図、図５は妻出入り口の下縁部を上側から見た図である。   FIG. 1A is a front view showing a sliding door device in a railway vehicle according to an embodiment of the present invention, FIG. 1B is a side view thereof, FIG. 2 is an explanatory diagram of opening and closing operations of the sliding door, and FIG. 4 is a front view showing the sliding door mounting structure, FIG. 4 is an enlarged view of portion A in FIG. 1B, and FIG.

図１〜図５に示すように、妻構体１１の妻出入り口１２の上部及び戸袋１３の上部に、戸閉装置１４が取付けられ、この戸閉装置１４の案内レール１５は、水平方向に対して戸袋１３側が高くなるように傾斜している。そして、その案内レール１５に妻引き戸１が吊り下げられ、人間の力で一方に引っ張って案内レール１５に沿って移動させることで開く一方、案内レール１５の傾斜による重力で自然に閉まるようになっている。   As shown in FIGS. 1 to 5, a door closing device 14 is attached to the upper portion of the wife doorway 12 and the upper portion of the door pocket 13 of the wife structure 11, and the guide rail 15 of the door closing device 14 is arranged in the horizontal direction. It inclines so that the door pocket 13 side may become high. Then, the sliding door 1 is suspended by the guide rail 15 and is opened by being pulled along one side by a human force and moved along the guide rail 15, while it is naturally closed by gravity due to the inclination of the guide rail 15. ing.

妻引き戸１は、図６〜図９に示すように、戸先側の、上下方向の延びる側縁部に、支持部材２を介して戸当たりゴム３（戸先ゴム）が取り付けられている。引き戸本体１Ａの戸先側において、室内側および車外側の下端部それぞれに、矩形板状の閉鎖板４，５が上下方向に移動自在に支持されている。なお、閉鎖板４，５の、戸先側縁部は、支持部材２より戸先側に突出しない構成とされている。   As shown in FIGS. 6 to 9, the door sliding door 1 has a door end rubber 3 (door rubber) attached to a side edge of the door tip side extending in the vertical direction via a support member 2. On the door end side of the sliding door main body 1A, rectangular plate-like closing plates 4 and 5 are supported movably in the vertical direction on the indoor side and the lower end of the vehicle exterior, respectively. In addition, the door edge side edge part of the closing plates 4 and 5 is set as the structure which does not protrude to the door edge side from the support member 2. FIG.

妻出入り口１２の、戸袋１３側の床面には、上方に突出するガイドピン２１(ガイド部材）が配置されている。引き戸本体１Ａの下端縁部は逆Ｕ字形状の部材２６が取り付けられることで凹んでおり、この凹んだ部分（部材２６）にガイドピン２１がスライド可能に係合し、妻引き戸１の開閉時に妻引き戸１が振れるのを防止するようになっている。なお、ガイドピン２１は平面視矩形状の取付板２２の上側に溶接されてガイドピン２１と取付板２２とが一体化され、その取付板２２が戸袋１３側の床面に取り付けられている。   A guide pin 21 (guide member) that protrudes upward is disposed on the floor surface of the doorway 12 on the door pocket 13 side. The lower end edge of the sliding door body 1A is recessed by attaching an inverted U-shaped member 26, and the guide pin 21 is slidably engaged with the recessed portion (member 26). The wife sliding door 1 is prevented from swinging. The guide pin 21 is welded to the upper side of the rectangular mounting plate 22 in plan view so that the guide pin 21 and the mounting plate 22 are integrated, and the mounting plate 22 is attached to the floor surface on the door pocket 13 side.

また、妻出入り口１２の、戸先側の床面には、下レール２３が設けられている。そして妻引き戸１を閉じたときに、前記凹んだ部分(部材２６)が下レール２３に係合し、風などによって妻引き戸１が振れるのを防止するようになっている。   A lower rail 23 is provided on the floor surface of the doorway side of the wife doorway 12. When the sliding door 1 is closed, the recessed portion (member 26) is engaged with the lower rail 23 to prevent the sliding door 1 from swinging due to wind or the like.

閉鎖板４，５には上下方向に延びる長孔４ａ，５ａがそれぞれ２つずつ形成され、妻引き戸１の引き戸本体１Ａには長孔４ａ、５ａにスライド可能に係合される係合ピン部材６が設けられている。よって、係合ピン部材６が閉鎖板４，５の長孔４ａ，５ａ内をスライド移動することで閉鎖板４，５が昇降する。   The closing plates 4 and 5 are each formed with two long holes 4a and 5a extending in the vertical direction, and the engaging pin member slidably engaged with the long holes 4a and 5a in the sliding door body 1A of the sliding door 1 6 is provided. Therefore, when the engaging pin member 6 slides in the long holes 4a and 5a of the closing plates 4 and 5, the closing plates 4 and 5 move up and down.

各係合ピン部材６は、先端がネジ部となった軸部６ａと、長孔４ａ，５ａよりも幅よりも径が大きい頭部６ｂとを有する。係合ピン部材６は、引き戸本体１Ａにネジ止めされるものであるが、軸部６ａの周囲には、閉鎖板４，５の板厚より長さが長いカラー７が外嵌され、係合ピン部材６のねじ込み量を規制し、閉鎖板４，５の自由な昇降を損なわない構成とされている。   Each engagement pin member 6 has a shaft portion 6a whose tip is a screw portion, and a head portion 6b having a diameter larger than the width of the long holes 4a and 5a. The engaging pin member 6 is screwed to the sliding door main body 1A, but a collar 7 having a length longer than the thickness of the closing plates 4 and 5 is fitted around the shaft portion 6a. The amount of screwing of the pin member 6 is restricted, and free elevation of the closing plates 4 and 5 is not impaired.

そして、閉鎖板４，５の下端縁は引き戸本体１Ａの下端縁よりさらに下方に位置するが、妻引き戸１の全開時に、ガイドピン２１の取付板２２に接触しない突出量となるように係合ピン部材６が長孔４ａ，５ａとの係合関係により規制されている。つまり、妻引き戸１の動作線Ｓ２は、図２に示すように、案内レール１５に沿って傾斜することになるが、閉鎖板４，５の動作線Ｓ１は、引き戸開放当初は、係合ピン部材６が長孔４ａ，５ａ内を下端側から上端側に向かって移動可能であるので、図２に示すように、ほぼ水平方向である。ガイドピン２１の取付板２２の手前（図２の点Ｐ参照）で係合ピン部材６が長孔４ａ，５ａの上端に達するので、それ以降は、係合ピン部材６を介して妻引き戸１によって持ち上げられ、閉鎖板４，５の動作線は妻引き戸１の動作線と平行になる。そして、妻引き戸１の全開時には、閉鎖板４，５の下端縁は、ガイドピン２１の取付板２２の上側まで持ち上げられ、閉鎖板４，５と取付板２２とは接触しない。   And although the lower end edge of the closing plates 4 and 5 is located further below the lower end edge of the sliding door main body 1A, it engages so that it may become the protrusion amount which does not contact the attachment board 22 of the guide pin 21 at the time of the fully open door sliding door 1. The pin member 6 is regulated by the engagement relationship with the long holes 4a and 5a. In other words, the operation line S2 of the sliding door 1 is inclined along the guide rail 15 as shown in FIG. 2, but the operation line S1 of the closing plates 4 and 5 is the engagement pin when the sliding door is initially opened. Since the member 6 can move in the long holes 4a and 5a from the lower end side toward the upper end side, as shown in FIG. 2, it is substantially horizontal. Since the engaging pin member 6 reaches the upper end of the long holes 4a and 5a before the mounting plate 22 of the guide pin 21 (refer to point P in FIG. 2), thereafter, the sliding door 1 is interposed via the engaging pin member 6. The operating lines of the closing plates 4 and 5 are parallel to the operating line of the sliding door 1. When the sliding door 1 is fully opened, the lower end edges of the closing plates 4 and 5 are lifted up to the upper side of the mounting plate 22 of the guide pin 21, and the closing plates 4 and 5 do not contact the mounting plate 22.

閉鎖板４，５は、室内側の閉鎖板４が車外側の閉鎖板５よりも上下方向の長さが長くなるように形成され、それぞれ閉鎖板４，５の上下方向の中間位置に長孔４ａ，５ａが形成されている。長孔４ａ，５ａは長さは同じであるが、その位置が室内側の閉鎖板４と車外側の閉鎖板５とにおいて、上下方向にずれている。そして、閉鎖板４，５が取り付けられた状態では、閉鎖板４，５の下端縁はほぼ一致する。   The closing plates 4, 5 are formed so that the indoor side closing plate 4 is longer in the vertical direction than the outer side closing plate 5, and each has a long hole at an intermediate position in the vertical direction of the closing plates 4, 5. 4a and 5a are formed. The long holes 4a and 5a have the same length, but their positions are shifted in the vertical direction between the indoor side closing plate 4 and the vehicle outer side closing plate 5. And in the state in which the closing plates 4 and 5 were attached, the lower end edges of the closing plates 4 and 5 substantially coincide.

続いて、本発明の前提となる戸閉装置１４について説明する。   Then, the door closing apparatus 14 used as the premise of this invention is demonstrated.

妻引き戸１の上端縁部の前後に間隔を存して１対の吊り金具３１，３２がボルトで固定され、戸先側の吊り金具３１に戸車３３が車軸（図示せず）を介して取り付けられ、さらに回転型油圧制御装置３４（回転型ドアチェック）が取り付けられている。また、戸尻側の吊り金具３２にも、具体的に図示していないが車軸を介して戸車が取り付けられている。   A pair of hanging brackets 31 and 32 are fixed with bolts in front of and behind the upper edge of the sliding door 1, and a door wheel 33 is attached to the hanging bracket 31 on the door end side via an axle (not shown). Further, a rotary hydraulic control device 34 (rotary door check) is attached. Moreover, although not specifically illustrated, the door cart is attached to the hanging metal fitting 32 on the door bottom side via an axle.

案内レール１５のレール面上を戸車３３が転動し、その際にガイドピン２１によって案内されて、妻引き戸１が前後方向に移動することで妻出入り口１２が開閉される。このとき、回転型油圧制御装置３４の歯車３４ａが戸閉装置１４の案内レール１５の下側ラックギア１５ａと噛み合い、さらにブレーキレール３５の上側ラックギア３５ａと噛み合って回転し、これによって妻引き戸１を閉方向、開方向のいずれの方向においてもドアチェック作用を奏するようになっている。   The door roller 33 rolls on the rail surface of the guide rail 15 and is guided by the guide pin 21 at that time. The wife sliding door 1 moves in the front-rear direction, thereby opening and closing the wife doorway 12. At this time, the gear 34a of the rotary hydraulic control device 34 meshes with the lower rack gear 15a of the guide rail 15 of the door closing device 14 and further meshes with the upper rack gear 35a of the brake rail 35, thereby rotating the door sliding door 1. The door check action is produced in both the direction and the opening direction.

妻引き戸１の戸車３３を支える案内レール１５は断面Ｌ形形状をしており、その水平部にラックギア１５ａがネジ止めして固定されている。この案内レール１５の左右両端にストッパー３６がネジ止めして設けられていて、妻引き戸１が全開、あるいは全閉したとき妻引き戸１に設けたストッパーローラ３７がこのストッパー３６に当接係合し、妻引き戸１を全開位置、全閉位置に保持する。このストッパー機構は従来周知のものであるから、その具体的な機構についての説明は省略する。ストッパーローラ３７は吊り金３１，３２にネジ止めされている。   The guide rail 15 that supports the door pulley 33 of the sliding door 1 has an L-shaped cross section, and a rack gear 15a is fixed to the horizontal portion by screws. Stoppers 36 are screwed to the left and right ends of the guide rail 15, and when the sliding door 1 is fully opened or fully closed, a stopper roller 37 provided on the sliding door 1 comes into contact with and engages with the stopper 36. The wife sliding door 1 is held in the fully open position and the fully closed position. Since this stopper mechanism is conventionally well-known, the description about the specific mechanism is abbreviate | omitted. The stopper roller 37 is screwed to the suspenders 31 and 32.

また、ブレーキレール３５も断面Ｌ形部材であり、その水平部にラックギア３５ａがネジ止めして固定されている。   The brake rail 35 is also an L-shaped member, and a rack gear 35a is fixed to the horizontal portion by screws.

左右両端にストッパー３６を備えた案内レール１５とブレーキレール３５とはレール支持台３８に取り付けられて、戸閉装置１４とされる。   The guide rail 15 provided with stoppers 36 at both left and right ends and the brake rail 35 are attached to a rail support base 38 to form the door closing device 14.

また、回転型油圧制御装置３４とレール１５，３５のラックギア１５ａ，３５ａとによるドアチェック機構は従来周知のもの（例えば特許第３０６９０９５号公報参照）であるから、その機構の具体的な説明は省略するが、回転型油圧制御装置３４は歯車３４ａの一方向の回転に対してはフリーであり、他方向への回転に対して油圧的にこれを制動するものである。したがって、全閉状態からの開動作の初期においては、歯車３４ａは案内レール１５のラックギア１５ａと噛み合って一方向にフリーに回転し、開動作の終期においてブレーキレール３５のラックギア３５ａと噛み合って、他方向に回転する。この他方向回転に対して回転型油圧制御装置３４が制動作用を奏するので、妻引き戸１は開動作の終期において制動される。また、全開状態からの閉動作の初期においては、歯車３４ａはブレーキレール３５のラックギア３５ａと噛み合って一方向にフリーに回転し、閉動作の終期において案内レール１５のラックギア１５ａと噛み合って制動力を受けながら他方向に回転する。したがって、妻引き戸１は開動作及び閉動作の終期において制動される。妻引き戸１が開動作の終点、閉動作の終点に達したとき、前後の吊り金３１，３２に設けたストッパーローラ３７が案内レール１５の左右両端に設けたストッパー３６に当接するので、妻引き戸１は閉位置、あるいは開位置のいずれにおいても所定の保持力で保持される。   The door check mechanism using the rotary hydraulic control device 34 and the rack gears 15a and 35a of the rails 15 and 35 is a well-known door check mechanism (see, for example, Japanese Patent No. 3069095), and a detailed description of the mechanism is omitted. However, the rotary hydraulic control device 34 is free for rotation in one direction of the gear 34a and hydraulically brakes the rotation in the other direction. Therefore, at the initial stage of the opening operation from the fully closed state, the gear 34a meshes with the rack gear 15a of the guide rail 15 and freely rotates in one direction, and at the end of the opening operation, meshes with the rack gear 35a of the brake rail 35. Rotate in the direction. Since the rotary hydraulic control device 34 exerts a braking action against the rotation in the other direction, the sliding door 1 is braked at the end of the opening operation. In the initial stage of the closing operation from the fully opened state, the gear 34a meshes with the rack gear 35a of the brake rail 35 and freely rotates in one direction. At the end of the closing operation, the gear 34a meshes with the rack gear 15a of the guide rail 15 and applies braking force. Rotate in the other direction while receiving. Accordingly, the sliding door 1 is braked at the end of the opening operation and the closing operation. When the door sliding door 1 reaches the end point of the opening operation and the end point of the closing operation, the stopper rollers 37 provided on the front and rear hanging hooks 31 and 32 come into contact with the stoppers 36 provided on the left and right ends of the guide rail 15. 1 is held with a predetermined holding force in either the closed position or the open position.

上記のように構成したので、妻引き戸１において、それの下端部の室内側および車外側に閉鎖板４，５が上下方向に移動可能に支持されているので、妻引き戸１を開放する際、開放当初は、係合ピン部材６が長孔４ａ，５ａ内を下端側から上端側に向かって移動する。これにより、妻引き戸１は下端縁と床面との隙間が徐々に大きくなるように移動する（図２の動作線Ｓ２参照）のに対し、閉鎖板４，５は下端縁が床面を摺動しつつ移動する（図２の動作線Ｓ１参照）。つまり、閉鎖板４，５は妻引き戸１の下端縁と床面との隙間を常時閉鎖するように水平移動する。   Since it comprised as mentioned above, since the closing plates 4 and 5 are supported so that it can move to the up-down direction in the indoor side and the vehicle outer side of the lower end part, when opening the sliding door 1, At the beginning of opening, the engaging pin member 6 moves in the long holes 4a and 5a from the lower end side toward the upper end side. Thereby, the sliding door 1 moves so that the gap between the lower edge and the floor surface gradually increases (see the operation line S2 in FIG. 2), whereas the lower edges of the closing plates 4 and 5 slide on the floor surface. It moves while moving (see operation line S1 in FIG. 2). That is, the closing plates 4 and 5 move horizontally so as to always close the gap between the lower edge of the sliding door 1 and the floor surface.

そして、ガイドピン２１の取付板２２の手前（動作線Ｓ１の点Ｐ参照）で係合ピン部材６が長孔４ａ，５ａの上端に達するので、それ以降は、係合ピン部材６を介して妻引き戸１によって持ち上げられるようになる（動作線Ｓ１参照）。そして、閉鎖板４，５の下端縁は、ガイドピン２１の取付板２２上側まで持ち上げられるので、妻引き戸１の全開時には、図７および図８に示すように、閉鎖板４，５と取付板２２とは接触しないことになる。この妻引き戸全開時には、引き戸本体１Ａの下端縁部の凹んだ部分（部材２６）にガイドピン２１がスライド可能に係合し、妻引き戸１が振れるのを防止するようになっている。   Since the engaging pin member 6 reaches the upper end of the long holes 4a and 5a before the mounting plate 22 of the guide pin 21 (see the point P of the operation line S1), thereafter, the engaging pin member 6 is interposed via the engaging pin member 6. The door is lifted by the door 1 (see operation line S1). And since the lower end edge of the closing plates 4 and 5 is lifted to the upper side of the mounting plate 22 of the guide pin 21, when the sliding door 1 is fully opened, as shown in FIG. 7 and FIG. 22 will not come into contact. When the sliding door is fully opened, the guide pin 21 is slidably engaged with the recessed portion (member 26) of the lower end edge of the sliding door body 1A to prevent the sliding door 1 from swinging.

そして、乗客などによって妻引き戸１を開放しようとする力が作用しないと、案内レール１５が傾斜しているので、重力の作用によって、妻引き戸１が妻出入り口１２を閉じる方向に移動する。そして、妻引き戸１が妻出入り口１２を閉じたときには、前記凹んだ部分（部材２６）が下レール２３に係合し、風などによる妻引き戸１の振れが防止される。   And if the force which opens the sliding door 1 by a passenger etc. does not act, since the guide rail 15 will incline, the sliding door 1 will move to the direction which closes the entrance / exit 12 by the effect | action of gravity. When the wife sliding door 1 closes the wife doorway 12, the recessed portion (member 26) engages with the lower rail 23, and the swing of the wife sliding door 1 due to wind or the like is prevented.

このように、妻引き戸１の下端縁の戸先側部分と床面との隙間が閉鎖板４，５によって閉鎖されるので、妻引き戸１の開閉の際に、妻引き戸１と床面との隙間に、サンダルなどを履いた乗客の足先が挟まれるのを防止することができる。   Thus, since the clearance between the door end side portion of the lower end edge of the wife sliding door 1 and the floor surface is closed by the closing plates 4 and 5, when the door sliding door 1 is opened and closed, the door sliding door 1 and the floor surface are separated. It is possible to prevent the feet of passengers wearing sandals from being caught in the gap.

特に、閉鎖板４，５が上下方向に移動可能に支持されているので、妻引き戸１の開閉動作が損なわれることはない。つまり、閉鎖板４，５の下端縁が床面に接触すると、閉鎖板４，５は上方に変位するので、妻引き戸１の開閉動作はスムーズに行われる。   In particular, since the closing plates 4 and 5 are supported so as to be movable in the vertical direction, the opening and closing operation of the sliding door 1 is not impaired. That is, when the lower end edges of the closing plates 4 and 5 come into contact with the floor surface, the closing plates 4 and 5 are displaced upward, so that the opening / closing operation of the sliding door 1 is performed smoothly.

また、妻引き戸１の振れ止め対策の、ガイドピン２１、下レール２３などを取り外さなくても、閉鎖板４，５を取り付けることができるので、既存の車両の妻引き戸１に、簡単に取り付けることができる。   Moreover, since the closing plates 4 and 5 can be attached without removing the guide pin 21 and the lower rail 23, etc., as a countermeasure against the steadying of the sliding door 1, it can be easily attached to the existing sliding door 1 of the vehicle. Can do.

前記実施の形態では、閉鎖板に上下方向に延びる長孔を形成し、妻引き戸に長孔にスライド可能に係合される係合ピン部材を設けているが、逆に、妻引き戸に上下方向に延びる長孔を形成し、閉鎖板に長孔にスライド可能に係合される係合ピン部材を設けるようにすることもできる。   In the above embodiment, a long hole extending in the vertical direction is formed in the closing plate, and the engagement pin member that is slidably engaged with the long hole is provided in the sliding door. In addition, an elongated pin extending into the elongated hole may be formed, and an engagement pin member slidably engaged with the elongated hole may be provided on the closing plate.

また、長孔と係合ピン部材との係合関係に限らず、例えば、（被係合部としての）凹部あるいは溝と、（係合部材としての）前記凹部或いは溝にスライド可能に係合する凸部部材との係合関係を利用することも可能である。   Further, not only the engagement relationship between the long hole and the engagement pin member, but also, for example, a recess or groove (as the engaged portion) and a slidable engagement with the recess or groove (as the engagement member) It is also possible to use the engagement relationship with the convex member.

さらに、前記実施の形態では、妻引き戸１の全開時に、長孔４ａ，５ａと係合ピン部材６との係合関係で、閉鎖板４，５を持ち上げることで、ガイドピン２１の取付板２２との接触（干渉）を回避するようにしているが、それに代えて、取付板の、戸先側部分を傾斜面として、閉鎖板がスムーズに載り上がるようにする構成とすることも可能である。   Furthermore, in the above-described embodiment, the mounting plate 22 of the guide pin 21 is lifted by lifting the closing plates 4 and 5 in the engaging relationship between the long holes 4a and 5a and the engaging pin member 6 when the sliding door 1 is fully opened. However, instead of this, it is also possible to adopt a configuration in which the closing plate is placed smoothly by using the door side portion of the mounting plate as an inclined surface. .
