Description

本発明は、鉄道車両の互いに連結された車両間の隙間を塞ぐ外幌装置に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer hood device for closing gaps between mutually connected railway vehicles.

鉄道車両の互いに連結された各車両間の隙間に走行風が巻き込まれて騒音が発生することを防止する外幌装置が知られている（例えば、特許文献１参照）。特許文献１の外幌装置は、一方の車両に固定される固定板と、他方の車両に接触する可動板と、固定板及び可動板の外端部同士に架け渡された幌部材とを備える。可動板は、Ｘ状に配置された第１リンク部材及び第２リンク部材からなるリンク機構を介して固定板に接続されている。第１リンク部材は固定板を可動板に連結し、第２リンク部材は一方の車両に設けられるスライド機構に可動板を連結する。第１リンク部材の端部と第２リンク部材の端部とは、車幅方向に延びる引張バネにより互いに近接する向きに付勢される。 2. Description of the Related Art There is known an outer hood device that prevents the generation of noise due to running wind being caught in gaps between railroad cars that are connected to each other (see, for example, Patent Document 1). The outer hood device of Patent Document 1 includes a fixed plate that is fixed to one vehicle, a movable plate that contacts the other vehicle, and a hood member that spans the outer ends of the fixed plate and the movable plate. . The movable plate is connected to the fixed plate via a link mechanism consisting of a first link member and a second link member arranged in an X shape. A first link member connects the fixed plate to the movable plate, and a second link member connects the movable plate to a slide mechanism provided on one vehicle. An end portion of the first link member and an end portion of the second link member are biased toward each other by a tension spring extending in the vehicle width direction.

特許第５０６８１９３号公報Japanese Patent No. 5068193

しかし、特許文献１の外幌装置は、リンク部材をＸ状に交差させるためにリンク部材が２つ必要であり、引張バネやスライド機構も必要である。そのため、外幌装置の占有スペースが大きくなり、幌部材で塞がれた空間に作業員が入ってメンテナンスを行う際の作業スペースが狭くなる。また、当該外幌装置は、部品点数が多いために重量も大きくなる。また、当該外幌装置のスライド機構には、摺動摩耗の対策のために定期的に潤滑剤を塗布する必要があり、メンテナンス工数が多くなる。 However, the outer hood device of Patent Document 1 requires two link members in order to cross the link members in an X shape, and also requires a tension spring and a slide mechanism. As a result, the space occupied by the outer hood device becomes large, and the working space becomes narrow when a worker enters the space closed by the hood member to perform maintenance. In addition, the outer hood device has a large number of parts, so the weight of the outer hood device is also large. In addition, the slide mechanism of the outer hood device needs to be periodically coated with a lubricant to prevent sliding wear, which increases the number of maintenance man-hours.

そこで本発明は、作業員の作業スペースを拡大し、重量低減を図り、メンテナンス工数を低減することを目的とする。 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to increase the work space for workers, reduce the weight, and reduce the number of maintenance steps.

本発明の一態様に係る鉄道車両の外幌装置は、鉄道車両の互いに連結された第１車両と第２車両との間の隙間を塞ぐ外幌装置であって、前記第１車両の妻面に固定される固定部材と、前記固定部材から前記第２車両側に離れて配置され、前記第２車両の妻面に設けられた摺り板に摺接する可動部材と、前記固定部材及び前記可動部材の外端部同士に架け渡された幌部材と、上面視において、車両長手方向に対して傾斜した状態で前記固定部材から前記可動部材に延び、前記固定部材に対して第１回動軸線周りに回動自在に接続されて且つ前記可動部材に対して第２回動軸線周りに回動自在に接続された１つのリンク部材と、上面視において前記固定部材に対する前記リンク部材の角度が増加する向きに前記リンク部材を付勢するように、前記第１回動軸線周りの捩じり力を発揮する固定側付勢部材と、を備える。 An outer hood device for a railway vehicle according to one aspect of the present invention is an outer hood device that closes a gap between a first vehicle and a second vehicle that are connected to each other of a railway vehicle, and comprises: a movable member disposed away from the fixed member toward the second vehicle and slidingly contacting a contact plate provided on the end surface of the second vehicle; the fixed member and the movable member; and a top member extending from the fixed member to the movable member in a state inclined with respect to the longitudinal direction of the vehicle in a top view, and around the first rotation axis with respect to the fixed member. and one link member rotatably connected to the movable member about a second rotation axis, and the angle of the link member with respect to the fixed member increases when viewed from the top. a fixed-side biasing member that exerts a torsional force about the first pivot axis so as to bias the link member in the direction.

前記構成によれば、リンク部材の回転軸線周りの捩じり力を発揮する付勢部材（例えば、捩じりバネやトーションバー等）によってリンク部材が付勢されて可動部材が第２車両の妻面に設けられる摺り板に摺接するので、リンク部材が１つで足りる。そのため、従来構成に比べてリンク部材の数を減らすことができるとともに引張バネやスライド機構も不要にできる。よって、作業員の作業スペースを拡大できると共に外幌装置の重量低減を図ることができる。また、従来構成のスライド機構が不要となって摺動部位を削減し得るので、メンテナンス工数も低減できる。 According to the above configuration, the link member is biased by the biasing member (for example, a torsion spring, a torsion bar, etc.) that exerts a torsional force about the rotation axis of the link member so that the movable member moves toward the second vehicle. One link member suffices because it is in sliding contact with the contact plate provided on the end surface. Therefore, the number of link members can be reduced compared to the conventional structure, and the tension spring and slide mechanism can be eliminated. Therefore, it is possible to expand the work space for the operator and reduce the weight of the outer hood device. In addition, since the slide mechanism of the conventional structure is no longer necessary, the number of sliding parts can be reduced, so the number of maintenance man-hours can also be reduced.

本発明の他態様に係る鉄道車両の外幌装置は、鉄道車両の互いに連結された第１車両と第２車両との間の隙間を塞ぐ外幌装置であって、前記第１車両の妻面に固定される固定部材と、前記固定部材から前記第２車両側に離れて配置され、前記第２車両の妻面に設けられた摺り板に摺接する可動部材と、前記固定部材及び前記可動部材の外端部同士に架け渡された幌部材と、上面視において、車両長手方向に対して傾斜した状態で前記固定部材から前記可動部材に延び、前記固定部材に対して第１回動軸線周りに回動自在に接続されて且つ前記可動部材に対して第２回動軸線周りに回動自在に接続された１つのリンク部材と、前記固定部材に対する前記リンク部材の角度が増加する向きに前記リンク部材を付勢するように、前記リンク部材を前記固定部材に接続するトグル機構と、を備える。 According to another aspect of the present invention, there is provided an outer hood device for a railway vehicle that closes a gap between a first vehicle and a second vehicle that are connected to each other of the railway vehicle, and comprises: a movable member disposed away from the fixed member toward the second vehicle and slidingly contacting a contact plate provided on the end surface of the second vehicle; the fixed member and the movable member; and a top member extending from the fixed member to the movable member in a state inclined with respect to the longitudinal direction of the vehicle in a top view, and around the first rotation axis with respect to the fixed member. one link member rotatably connected to and rotatably connected to the movable member about a second rotation axis; a toggle mechanism connecting the link member to the fixed member to bias the link member.

前記構成によれば、トグル機構によりリンク部材を付勢することで、リンク部材が１つで足りる。そのため、従来構成に比べてリンク部材の数を減らすことができるとともに引張バネやスライド機構も不要にできる。よって、作業員の作業スペースを拡大できると共に外幌装置の重量低減を図ることができる。また、従来構成のスライド機構が不要となって摺動部位を削減し得るので、メンテナンス工数も低減できる。 According to the above configuration, one link member is sufficient by biasing the link member by the toggle mechanism. Therefore, the number of link members can be reduced compared to the conventional structure, and the tension spring and slide mechanism can be eliminated. Therefore, it is possible to expand the work space for the operator and reduce the weight of the outer hood device. In addition, since the slide mechanism of the conventional structure is no longer necessary, the number of sliding parts can be reduced, so the number of maintenance man-hours can also be reduced.

本発明によれば、作業員の作業スペースを拡大でき、重量低減を図ることができ、メンテナンス工数を低減できる。 According to the present invention, it is possible to expand the work space for workers, reduce the weight, and reduce the number of maintenance man-hours.

The link member 14 has a body portion 14a, a pair of fixed side arm portions 14b, and a pair of movable side arm portions 14c. The body portion 14a has a plate shape. The main body portion 14a is arranged so that its normal line faces the horizontal direction and extends in the vertical direction. The pair of fixed-side arm portions 14b protrude toward the fixed member 11 from the upper end portion and the lower end portion of the main body portion 14a. The pair of movable arm portions 14c protrude toward the movable member 12 from the upper end portion and the lower end portion of the body portion 14a. When viewed from above, the link member 14 has a connection portion (movable-side rotation support shaft 16) between the movable member 12 and the link member 14, and a connection portion (fixed-side rotation support shaft 15) between the fixed member 11 and the link member 14. It is inclined in the direction of being arranged on the inner side in the vehicle width direction.

固定側回動支軸１５は、リンク部材１４の固定側アーム部１４ｂが固定部材１１の第１ブラケット部１１ｂに鉛直方向に重ねられた状態で、固定部材１１の第１ブラケット部１１ｂ及び第２ブラケット部１１ｃとリンク部材１４の固定側アーム部１４ｂとを鉛直方向に貫通している。即ち、リンク部材１４は、固定側回動支軸１５の中心線（鉛直線）を第１回動軸線Ｘ１として固定部材１１に回動自在に接続されている。 The fixed-side rotation support shaft 15 is attached to the first bracket portion 11b of the fixed member 11 and the second bracket portion 11b of the fixed member 11 in a state in which the fixed-side arm portion 14b of the link member 14 is superimposed on the first bracket portion 11b of the fixed member 11 in the vertical direction. It penetrates the bracket portion 11c and the fixed side arm portion 14b of the link member 14 in the vertical direction. That is, the link member 14 is rotatably connected to the fixed member 11 with the center line (vertical line) of the fixed side rotation support shaft 15 as the first rotation axis X1.

可動側回動支軸１６は、リンク部材１４の可動側アーム部１４ｃが可動部材１２の第１ブラケット部１２ｂに鉛直方向に重ねられた状態で、可動部材１２の第１ブラケット部１２ｂ及び第２ブラケット部１２ｃとリンク部材１４の可動側アーム部１４ｃとを鉛直方向に貫通している。即ち、可動部材１２は、可動側回動支軸１６の中心線（鉛直線）を第２回動軸線Ｘ２としてリンク部材１４に回動自在に接続されている。 The movable-side pivoting support shaft 16 is arranged in a state in which the movable-side arm portion 14c of the link member 14 is superimposed on the first bracket portion 12b of the movable member 12 in the vertical direction. It penetrates the bracket part 12c and the movable arm part 14c of the link member 14 in the vertical direction. That is, the movable member 12 is rotatably connected to the link member 14 with the center line (vertical line) of the movable-side rotation support shaft 16 as the second rotation axis X2.

固定側ピン１７は、リンク部材１４の固定側アーム部１４ｂに対して一体に設けられ、鉛直方向に突出している。即ち、リンク部材１４が第１回動軸線Ｘ１周りに傾動したときに、固定側ピン１７もリンク部材１４と一体に第１回動軸線Ｘ１周りに移動する。なお、固定側ピン１７は、固定側アーム部１４ｂに対して自転可能でもよいし自転不能でもよい。 The fixed-side pin 17 is provided integrally with the fixed-side arm portion 14b of the link member 14 and protrudes in the vertical direction. That is, when the link member 14 tilts around the first rotation axis X1, the stationary pin 17 also moves together with the link member 14 around the first rotation axis X1. The stationary pin 17 may or may not be rotatable with respect to the stationary arm portion 14b.

固定部材１１の第１ブラケット部１１ｂには、固定側ピン１７が挿通される第１案内孔Ｈ１が形成されている。固定側ピン１７は、第１案内孔Ｈ１を通過して第１ブラケット部１１ｂよりも第２ブラケット部１１ｃ側に突出している。第１案内孔Ｈ１は、リンク部材１４の傾動に伴う固定側ピン１７の移動軌跡に沿って延び、固定側ピン１７の移動可能範囲（即ち、リンク部材１４の傾動可能な角度範囲）を規定している。 The first bracket portion 11b of the fixed member 11 is formed with a first guide hole H1 through which the fixed side pin 17 is inserted. The fixed-side pin 17 passes through the first guide hole H1 and protrudes toward the second bracket portion 11c from the first bracket portion 11b. The first guide hole H1 extends along the locus of movement of the stationary pin 17 accompanying the tilting of the link member 14, and defines the movable range of the stationary pin 17 (that is, the angular range in which the link member 14 can be tilted). ing.

可動側ピン１８は、リンク部材１４の可動側アーム部１４ｃに対して一体に設けられ、鉛直方向に突出している。即ち、リンク部材１４が第２回動軸線Ｘ２周りに傾動したときに、可動側ピン１８もリンク部材１４と一体に第２回動軸線Ｘ２周りに移動する。なお、可動側ピン１８は、可動側アーム部１４ｃに対して自転可能でもよいし自転不能でもよい。 The movable-side pin 18 is provided integrally with the movable-side arm portion 14c of the link member 14 and protrudes in the vertical direction. That is, when the link member 14 tilts around the second rotation axis X2, the movable pin 18 also moves together with the link member 14 around the second rotation axis X2. The movable pin 18 may or may not be rotatable with respect to the movable arm portion 14c.

可動部材１２の第１ブラケット部１２ｂには、可動側ピン１８が挿通される第２案内孔Ｈ２が形成されている。可動側ピン１８は、第２案内孔Ｈ２を通過して第１ブラケット部１２ｂよりも第２ブラケット部１２ｃ側に突出している。第２案内孔Ｈ２は、リンク部材１４の傾動に伴う可動側ピン１８の移動軌跡に沿って延び、可動側ピン１８の移動可能範囲（即ち、リンク部材１４の傾動可能な角度範囲）を規定している。 The first bracket portion 12b of the movable member 12 is formed with a second guide hole H2 through which the movable pin 18 is inserted. The movable-side pin 18 passes through the second guide hole H2 and protrudes toward the second bracket portion 12c from the first bracket portion 12b. The second guide hole H2 extends along the locus of movement of the movable pin 18 as the link member 14 tilts, and defines the movable range of the movable pin 18 (that is, the angular range in which the link member 14 can tilt). ing.

固定側捩じりバネ１９は、コイル部１９ａと、第１バネ端部１９ｂと、第２バネ端部１９ｃとを有する。第１バネ端部１９ｂは、コイル部１９ａの一端部からコイル部１９ａの第１中心線Ｃ１に直交する方向に突出している。第２バネ端部１９ｃは、コイル部１９ａの他端部からコイル部１９ａの第１中心線Ｃ１に直交する方向に突出している。固定側捩じりバネ１９は、固定部材１１の第１ブラケット部１１ｂと第２ブラケット部１１ｃとの間に配置され、固定側回動支軸１５が挿通される。固定側捩じりバネ１９の第１中心線Ｃ１は、リンク部材１４の第１回動軸線Ｘ１と一致している。第１バネ端部１９ｂは、リンク部材１４に設けられた固定側ピン１７の外周面に押し当てられている。第２バネ端部１９ｃは、第２ブラケット部１１ｃに支持されている。 The fixed-side torsion spring 19 has a coil portion 19a, a first spring end portion 19b, and a second spring end portion 19c. The first spring end portion 19b protrudes from one end portion of the coil portion 19a in a direction perpendicular to the first center line C1 of the coil portion 19a. The second spring end portion 19c protrudes from the other end portion of the coil portion 19a in a direction perpendicular to the first center line C1 of the coil portion 19a. The fixed-side torsion spring 19 is arranged between the first bracket portion 11b and the second bracket portion 11c of the fixed member 11, and the fixed-side pivot shaft 15 is inserted therethrough. A first center line C1 of the fixed torsion spring 19 coincides with a first rotation axis X1 of the link member 14 . The first spring end portion 19b is pressed against the outer peripheral surface of the stationary pin 17 provided on the link member 14 . The second spring end portion 19c is supported by the second bracket portion 11c.

固定側捩じりバネ１９は、その第１中心線Ｃ１周りの捩じり力（回転付勢力）を発揮する。固定側ピン１７が固定側捩じりバネ１９の第１バネ端部１９ｂによって押されることで、上面視において固定部材１１に対するリンク部材１４の角度θ１が増加する向きにリンク部材１４が付勢される。固定側ピン１７の移動軌跡上に位置する第１案内孔Ｈ１の内周縁は、固定側捩じりバネ１９の捩じり力によりリンク部材１４が所定角度を超えて角変位する（角度θ１が所定角を超える）ことを規制する第１ストッパＳＴ１として機能する。 The fixed-side torsion spring 19 exerts a torsional force (rotational biasing force) around its first center line C1. The fixed-side pin 17 is pushed by the first spring end portion 19b of the fixed-side torsion spring 19, so that the link member 14 is biased in a direction in which the angle θ1 of the link member 14 with respect to the fixed member 11 increases in top view. be. The inner peripheral edge of the first guide hole H1 located on the locus of movement of the stationary pin 17 is angularly displaced by the torsion force of the stationary torsion spring 19 by the link member 14 exceeding a predetermined angle (the angle θ1 is It functions as a first stopper ST1 that restricts the angle from exceeding a predetermined angle.

可動側捩じりバネ２０は、コイル部２０ａと、第１バネ端部２０ｂと、第２バネ端部２０ｃとを有する。第１バネ端部２０ｂは、コイル部２０ａの一端部からコイル部２０ａの第２中心線Ｃ２に直交する方向に突出している。第２バネ端部２０ｃは、コイル部２０ａの他端部からコイル部２０ａの第２中心線Ｃ２に直交する方向に突出している。可動側捩じりバネ２０は、可動部材１２の第１ブラケット部１２ｂと第２ブラケット部１２ｃとの間に配置され、可動側回動支軸１６が挿通される。可動側捩じりバネ２０の第２中心線Ｃ２は、リンク部材１４の第２回動軸線Ｘ２と一致している。第１バネ端部２０ｂは、リンク部材１４に設けられた可動側ピン１８の外周面に押し当てられている。第２バネ端部２０ｃは、第２ブラケット部１２ｃに支持されている。 The movable-side torsion spring 20 has a coil portion 20a, a first spring end portion 20b, and a second spring end portion 20c. The first spring end portion 20b protrudes from one end portion of the coil portion 20a in a direction perpendicular to the second center line C2 of the coil portion 20a. The second spring end portion 20c protrudes from the other end portion of the coil portion 20a in a direction perpendicular to the second center line C2 of the coil portion 20a. The movable-side torsion spring 20 is arranged between the first bracket portion 12b and the second bracket portion 12c of the movable member 12, and the movable-side pivot shaft 16 is inserted therethrough. The second centerline C2 of the movable torsion spring 20 coincides with the second rotation axis X2 of the link member 14. As shown in FIG. The first spring end portion 20b is pressed against the outer peripheral surface of the movable pin 18 provided on the link member 14 . The second spring end portion 20c is supported by the second bracket portion 12c.

可動側捩じりバネ２０は、その中心線Ｃ２周りの捩じり力（回転付勢力）を発揮する。可動側ピン１８が可動側捩じりバネ２０の第１バネ端部２０ｂによって押されることで、上面視においてリンク部材１４に対して可動部材１２の角度θ２が増加する向きにリンク部材１４が付勢される。可動側ピン１８の移動軌跡上に位置する第２案内孔Ｈ２の内周縁は、可動側捩じりバネ２０の捩じり力により可動部材１２が所定角度を超えて角変位する（角度θ２が所定角を超える）ことを規制する第２ストッパＳＴ２として機能する。 The movable-side torsion spring 20 exerts a torsional force (rotational biasing force) around its center line C2. When the movable pin 18 is pushed by the first spring end portion 20b of the movable torsion spring 20, the link member 14 is attached in a direction that increases the angle θ2 of the movable member 12 with respect to the link member 14 when viewed from above. Forced. At the inner peripheral edge of the second guide hole H2 located on the movement locus of the movable pin 18, the movable member 12 is angularly displaced over a predetermined angle due to the torsional force of the movable torsion spring 20 (the angle θ2 is It functions as a second stopper ST2 that restricts that the predetermined angle is exceeded.

可動部材１２は、固定部材１１に対するリンク部材１４の回動とは独立して回動可能にリンク部材１４に接続されている。固定側ピン１７が第１ストッパＳＴ１に当接し且つ可動側ピン１８が第２ストッパＳＴ２に当接した状態が、外幌装置１０のホームポジション状態である。外幌装置１０がホームポジション状態にあるとき、可動部材１２のプレート部１２ａは、固定部材１１のプレート部１１ａに対して平行である。 The movable member 12 is rotatably connected to the link member 14 independently of the rotation of the link member 14 with respect to the fixed member 11 . The home position state of the outer hood device 10 is a state in which the fixed side pin 17 is in contact with the first stopper ST1 and the movable side pin 18 is in contact with the second stopper ST2. The plate portion 12a of the movable member 12 is parallel to the plate portion 11a of the fixed member 11 when the outer hood device 10 is in the home position state.

図４は、図２の外幌装置１０の回動時の上面図である。図４に示すように、可動部材１２が固定部材１１に近づくように外力が作用すると、固定側ピン１７が固定側捩じりバネ１９の付勢力に抗して第１バネ端部１９ｂを押して第１案内孔Ｈ１内を移動することで、リンク部材１４が第１回動軸線Ｘ１周りに傾動（角度θ１が減少）する。更に、上面視において可動部材１２が固定部材１１に対して傾斜（角度θ２が減少）するように外力が作用すると、可動側ピン１８が可動側捩じりバネ２０の付勢力に抗して第１バネ端部２０ｂを押して第２案内孔Ｈ２内を移動することで、可動部材１２が第２回動軸線Ｘ２周りに傾動する。そして、可動部材１２が擦り板２１上を車幅方向内方へ摺動することにより、幌部材１３の可撓部１３ｃは、固定部材１１に対する可動部材１２の変位に応じて自在に撓む。 FIG. 4 is a top view of the outer hood device 10 of FIG. 2 during rotation. As shown in FIG. 4, when an external force acts so that the movable member 12 approaches the fixed member 11, the fixed side pin 17 resists the biasing force of the fixed side torsion spring 19 and pushes the first spring end 19b. By moving in the first guide hole H1, the link member 14 tilts (the angle θ1 decreases) about the first rotation axis X1. Further, when an external force acts such that the movable member 12 is tilted (the angle θ2 is decreased) with respect to the fixed member 11 as viewed from above, the movable pin 18 resists the biasing force of the movable torsion spring 20 and moves to the first position. By pushing the first spring end portion 20b to move in the second guide hole H2, the movable member 12 tilts around the second rotation axis X2. As the movable member 12 slides inward in the vehicle width direction on the scraping plate 21 , the flexible portion 13 c of the top member 13 freely bends according to the displacement of the movable member 12 with respect to the fixed member 11 .

図５は、図１の鉄道車両ＲＣの曲線通過時の上面図である。図５に示すように、鉄道車両ＲＣの曲線通過時（例えば、車両基地内に設けられた急曲線通過時）には、上面視において第１車両１の妻面１ａと第２車両２の妻面２ａとの間の距離及び角度が変化する。曲線内側の外幌装置１０は、第２車両２の妻面２ａに可動部材１２が固定部材１１に向けて押されることで、リンク部材１４が固定部材１１に対して傾動する。その際、上面視において妻面２ａの傾動に追従するように可動部材１２がリンク部材１４に対して傾動する。曲線外側の外幌装置１０は、第２車両２の妻面２ａに設けられた擦り板２１が可動部材１２から離れるので、ホームポジション状態のままとなる。 FIG. 5 is a top view of the railway vehicle RC of FIG. 1 when passing through a curve. As shown in FIG. 5, when the railway vehicle RC passes through a curve (for example, when it passes through a sharp curve provided in a depot), the gable surface 1a of the first vehicle 1 and the gable surface 1a of the second vehicle 2 are viewed from above. The distance and angle with the surface 2a change. In the outer hood device 10 on the inner side of the curve, the movable member 12 is pushed toward the fixed member 11 by the end surface 2 a of the second vehicle 2 , so that the link member 14 tilts with respect to the fixed member 11 . At that time, the movable member 12 tilts with respect to the link member 14 so as to follow the tilting of the end surface 2a when viewed from above. Since the rubbing plate 21 provided on the end surface 2a of the second vehicle 2 is separated from the movable member 12, the outer hood device 10 on the outer side of the curve remains in the home position state.

以上に説明した構成によれば、一方向に斜めに延びたリンク部材１４の回転軸線Ｘ１，Ｘ２周りの捩じり力を発揮する固定側捩じりバネ１９及び可動側捩じりバネ２０によってリンク部材１４が付勢されて可動部材１２が第２車両２の妻面２ａに設けられた擦り板２１に摺接し、リンク部材１４が１つで足りる。そのため、従来構成に比べてリンク部材１４の数を減らすことができるとともに引張バネやスライド機構も不要にできる。よって、作業員の作業スペース（貫通幌３と外幌装置１０との間のスペース）を拡大できると共に外幌装置１０の重量低減を図ることができる。また、従来構成のスライド機構が不要となって摺動部位を削減し得るので、メンテナンス工数も低減できる。 According to the configuration described above, the fixed-side torsion spring 19 and the movable-side torsion spring 20 exerting torsional force around the rotation axes X1 and X2 of the link member 14 extending obliquely in one direction The link member 14 is energized to bring the movable member 12 into sliding contact with the scraping plate 21 provided on the end surface 2a of the second vehicle 2, and one link member 14 is sufficient. Therefore, the number of link members 14 can be reduced compared to the conventional structure, and the tension spring and slide mechanism can be eliminated. Therefore, the work space for the worker (the space between the penetrating hood 3 and the outer hood device 10) can be expanded, and the weight of the outer hood device 10 can be reduced. In addition, since the slide mechanism of the conventional structure is no longer necessary, the number of sliding parts can be reduced, so the number of maintenance man-hours can also be reduced.

また、リンク部材１４は、可動部材１２とリンク部材１４との接続部（可動側回動支軸１６）が固定部材１１とリンク部材１４との接続部（固定側回動支軸１５）よりも車幅方向内側に配置される向きに傾斜している。そのため、鉄道車両ＲＣの曲線通過時に、可動部材１２が第２車両２の妻面２ａに設けられた擦り板２１に押されて固定部材１１に近づくように変位してリンク部材１４が車両長手方向に対して大きく傾斜しても、可動部材１２は車幅方向外側ではなく車幅方向内側に移動することになる。よって、可動部材１２の車幅方向変位によって外幌装置１０が車両限界を超えることを防止できる。 In addition, the link member 14 has a connection portion (movable-side rotation support shaft 16) between the movable member 12 and the link member 14, which is closer than a connection portion (fixed-side rotation support shaft 15) between the fixed member 11 and the link member 14. It is slanted toward the inner side in the vehicle width direction. Therefore, when the railway vehicle RC passes through a curve, the movable member 12 is pushed by the scraping plate 21 provided on the end surface 2a of the second vehicle 2 and is displaced so as to approach the fixed member 11, and the link member 14 moves in the longitudinal direction of the vehicle. , the movable member 12 moves not to the outside in the vehicle width direction but to the inside in the vehicle width direction. Therefore, it is possible to prevent the outer hood device 10 from exceeding the vehicle limit due to the displacement of the movable member 12 in the vehicle width direction.

また、可動部材１２は、固定部材１１に対するリンク部材１４の回動とは独立して回動可能にリンク部材１４に接続されているので、可動部材１２が第２車両２の妻面２ａから擦り板２１を介して荷重を受けても、可動部材１２がリンク部材１４に対して自在に角変位できる。そのため、外幌装置１０に応力集中が発生しにくくなり、外幌装置１０の強度要求が緩和され、外幌装置１０を軽量化することができる。 In addition, since the movable member 12 is connected to the link member 14 so as to be rotatable independently of the rotation of the link member 14 with respect to the fixed member 11, the movable member 12 rubs against the end surface 2a of the second vehicle 2. Even if a load is applied via the plate 21, the movable member 12 can be freely angularly displaced with respect to the link member 14. - 特許庁Therefore, stress concentration is less likely to occur in the outer hood device 10, the strength requirements of the outer hood device 10 are relaxed, and the weight of the outer hood device 10 can be reduced.

また、固定側捩じりバネ１９及び可動側捩じりバネ２０の捩じり力によりリンク部材１４が所定角度を超えて角変位することを規制する第１ストッパＳＴ１及び第２ストッパＳＴ２が設けられているため、外幌装置１０がホームポジション状態に保持され、可動部材１２から第２車両２の妻面２ａに設けられた擦り板２１が離れても、外幌装置１０に無用なバタつき動作が発生することを防止できる。 Further, a first stopper ST1 and a second stopper ST2 are provided to prevent the link member 14 from being angularly displaced beyond a predetermined angle due to the torsional forces of the fixed-side torsion spring 19 and the movable-side torsion spring 20. Therefore, even if the outer hood device 10 is held in the home position state and the scraping plate 21 provided on the end surface 2a of the second vehicle 2 is separated from the movable member 12, the outer hood device 10 unnecessarily flutters. Actions can be prevented from occurring.

また、固定側捩じりバネ１９の中心線Ｃ１が第１回動軸線Ｘ１と一致して且つ可動側捩じりバネ２０の第２中心線Ｃ２が第２回動軸線Ｘ２と一致するので、固定側捩じりバネ１９及び可動側捩じりバネ２０がコンパクトに配置され、作業員の作業スペースの拡大に寄与できる。また、Ｘリンク方式と異なり、リンク部材１４が１つしかないことで、固定部材１１の車幅方向内端が可動部材１２の車幅方向内端よりも車幅方向外側に位置するように固定部材１１を車幅方向に短くできるので、外幌装置１０の軽量化に寄与できる。 Further, since the center line C1 of the fixed side torsion spring 19 coincides with the first rotation axis X1 and the second center line C2 of the movable side torsion spring 20 coincides with the second rotation axis X2, The fixed-side torsion spring 19 and the movable-side torsion spring 20 are arranged compactly, which contributes to the expansion of the work space for the worker. In addition, unlike the X-link system, since there is only one link member 14, the inner end of the fixed member 11 in the vehicle width direction is fixed so as to be positioned further outward in the vehicle width direction than the inner end of the movable member 12 in the vehicle width direction. Since the member 11 can be shortened in the vehicle width direction, the weight of the outer hood device 10 can be reduced.

図６は、付勢部材の変形例を示す平面図である。図７は、図６の付勢部材の取り付け状態を示す斜視図である。図６及び７に示すように、付勢部材としての固定側捩じりバネ１９及び可動側捩じりバネ２０の少なくとも一方に代えて、トーションバー１１９が用いられてもよい。１本のロッドで形成された通常のトーションバーが用いられてもよいが、本変形例では特別なトーションバー１１９が用いられる。図６及び７では固定側捩じりバネ１９をトーションバー１１９に代える例を説明するが、可動側捩じりバネ２０をトーションバー１１９に代えてもよい。なお、前述した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。 FIG. 6 is a plan view showing a modification of the biasing member. 7 is a perspective view showing an attached state of the biasing member of FIG. 6. FIG. As shown in FIGS. 6 and 7, a torsion bar 119 may be used instead of at least one of the fixed side torsion spring 19 and the movable side torsion spring 20 as the biasing member. A normal torsion bar formed by a single rod may be used, but in this variant a special torsion bar 119 is used. 6 and 7 illustrate an example in which the fixed side torsion spring 19 is replaced with the torsion bar 119, but the movable side torsion spring 20 may be replaced with the torsion bar 119. FIG. In addition, the same code|symbol is attached|subjected about the structure which is common in embodiment mentioned above, and description is abbreviate|omitted.

トーションバー１１９は、角形のロッド部１１９ａと、ロッド部１１９ａが部分的に挿入された筒部１１９ｂとを有する。トーションバー１１９の中心線Ｃは、前述した第１回動軸線Ｘ１に一致する。ロッド部１１９ａの一端部側は筒部１１９ｂの外部に出ている。ロッド部１１９ａの他端部側は、筒部１１９ｂの内部に収容されている。ロッド部１１９ａの他端部は、筒部１１９ｂの他端部と合致する穴１１９ｃに挿入されている。即ち、ロッド部１１９ａの他端部は、筒部１１９ｂの他端部と一体的に中心線Ｃ周りに回動する。 The torsion bar 119 has a rectangular rod portion 119a and a cylindrical portion 119b into which the rod portion 119a is partially inserted. A center line C of the torsion bar 119 coincides with the above-described first rotation axis X1. One end side of the rod portion 119a protrudes outside the cylindrical portion 119b. The other end side of the rod portion 119a is accommodated inside the cylindrical portion 119b. The other end of the rod portion 119a is inserted into a hole 119c that matches the other end of the cylindrical portion 119b. That is, the other end of the rod portion 119a rotates around the center line C integrally with the other end of the cylindrical portion 119b.

固定部材１１のプレート部１１ａには、ロッド部１１９ａの一端部に合致する形状を有する穴１１１ｄが形成された回動規制部１１１ｃが設けられている。ロッド部１１９ａの一端部は、回動規制部１１１ｃの穴１１１ｄに挿入されている。即ち、ロッド部１１９ａの一端部は、回動規制部１１１ｃによって固定部材１１に対して中心線Ｃ周りに回動不能に支持される。筒部１１９ｂは、リンク部材１４の固定側アーム部１４ｂに挿通されている。筒部１１９ｂのうちリンク部材１４の固定側アーム部１４ｂに挿入される部分には、中心線Ｃの方向から見て非円形の外形を有する係合部１１９ｄが設けられている。固定側アーム部１４ｂには、係合部１１９ｄに合致する形状を有する穴１４ｄが形成されており、係合部１１９ｄが穴１４ｄに嵌合している。即ち、筒部１１９ｂの係合部１１９ｄは、リンク部材１４に対して中心線Ｃ周りに回動不能に支持される。リンク部材１４から係合部１１９ｄに捩じり力が加わると、その捩じり力は筒部１１９ｂの一端部から他端部に伝達されてからロッド部１１９ａの他端部から一端部に伝達されて回動規制部１１１ｃで受け止められる。即ち、トーションバー１１９には、ロッド部１１９ａの一端部と筒部１１９ｂの係合部１１９ｄとの間で第１回動軸線Ｘ１周りの捩じり力が発生する。 The plate portion 11a of the fixing member 11 is provided with a rotation restricting portion 111c formed with a hole 111d having a shape matching one end portion of the rod portion 119a. One end of the rod portion 119a is inserted into the hole 111d of the rotation restricting portion 111c. That is, one end of the rod portion 119a is supported by the rotation restricting portion 111c so as not to rotate about the center line C with respect to the fixed member 11. As shown in FIG. The cylindrical portion 119b is inserted through the fixed arm portion 14b of the link member 14 . An engaging portion 119d having a non-circular outer shape when viewed from the direction of the center line C is provided in a portion of the cylindrical portion 119b that is inserted into the fixed-side arm portion 14b of the link member 14. As shown in FIG. A hole 14d having a shape matching the engaging portion 119d is formed in the fixed arm portion 14b, and the engaging portion 119d is fitted into the hole 14d. That is, the engaging portion 119d of the tubular portion 119b is supported by the link member 14 so as not to rotate around the center line C. As shown in FIG. When a twisting force is applied from the link member 14 to the engaging portion 119d, the twisting force is transmitted from one end of the cylindrical portion 119b to the other end and then transmitted from the other end of the rod portion 119a to the one end. and received by the rotation restricting portion 111c. That is, in the torsion bar 119, a twisting force around the first rotation axis X1 is generated between one end of the rod portion 119a and the engaging portion 119d of the cylindrical portion 119b.

トーションバー１１９の捩じれの実効長さは、ロッド部１１９ａの長さと筒部１１９ｂの長さとの和となる。他方、ロッド部１１９ａの一端部と筒部１１９ｂの係合部１１９ｄとの間の距離は、その実行長さよりも短く、ロッド部１１９ａの長さよりも短い。よって、トーションバー１１９によれば、回動規制部１１１ｃに支持される部分とリンク部材１４に支持される部分との間の距離を短くしながらも、捩じれの実効長さを長く確保できる。なお、他の構成は前述した実施形態と同様であるため説明を省略する。また、固定側付勢部材又は可動側付勢部材の一方を捩じりバネとし、固定側付勢部材又は可動側付勢部材の他方をトーションバーとしてもよい。 The effective twist length of the torsion bar 119 is the sum of the length of the rod portion 119a and the length of the cylindrical portion 119b. On the other hand, the distance between one end of the rod portion 119a and the engaging portion 119d of the cylindrical portion 119b is shorter than its effective length and shorter than the length of the rod portion 119a. Therefore, according to the torsion bar 119, it is possible to secure a long effective twist length while shortening the distance between the portion supported by the rotation restricting portion 111c and the portion supported by the link member . Since other configurations are the same as those of the above-described embodiment, description thereof is omitted. Alternatively, one of the fixed-side biasing member and the movable-side biasing member may be a torsion spring, and the other of the fixed-side biasing member and the movable-side biasing member may be a torsion bar.

（第２実施形態）
図８は、第２実施形態の外幌装置２１０の上面図である。図８に示すように、外幌装置２１０では、前述した実施形態における固定側ピン１７、固定側捩じりバネ１９及び第１案内孔Ｈ１が廃止され、その代わりにトグル機構２３０が用いられる。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。トグル機構２３０は、固定部材１１に対するリンク部材１４の角度が増加する向きにリンク部材１４を付勢するようにリンク部材１４を固定部材１１に接続している。トグル機構２３０は、第１アーム２３１と、第２アーム２３２と、回動支軸２３３、第１連結バー２３４と、第２連結バー２３５と、ピン２３６と、引張バネ２３７と、第１当接部材２３８と、第２当接部材２３９と、を備える。 (Second embodiment)
FIG. 8 is a top view of the outer hood device 210 of the second embodiment. As shown in FIG. 8, in the outer hood device 210, the fixed-side pin 17, the fixed-side torsion spring 19 and the first guide hole H1 in the above-described embodiment are eliminated, and a toggle mechanism 230 is used instead. In addition, the same code|symbol is attached|subjected about the structure which is common in 1st Embodiment, and description is abbreviate|omitted. The toggle mechanism 230 connects the link member 14 to the fixed member 11 so as to bias the link member 14 in a direction that increases the angle of the link member 14 with respect to the fixed member 11 . The toggle mechanism 230 includes a first arm 231, a second arm 232, a pivot shaft 233, a first connecting bar 234, a second connecting bar 235, a pin 236, a tension spring 237, and a first contact arm. A member 238 and a second contact member 239 are provided.

第１アーム２３１の一端部は、固定部材１１のプレート部１１ａに回動可能に接続されている。第２アーム２３２の一端部は、リンク部材１４に回動可能に接続されている。第１アーム２３１の他端部と第２アーム２３２の他端部とは、互いに回動支軸２３３にて回動可能に接続されている。第１アーム２３１及び第２アーム２３２は、Ｖ形状を呈するように配置されており、それらの間において第１連結バー２３４及び第２連結バー２３５は、Ｘ形状を呈するように配置されている。第１連結バー２３４と第２連結バー２３５とは、互いに交差する部分がピン２３６で回動可能に接続されている。 One end of the first arm 231 is rotatably connected to the plate portion 11a of the fixed member 11 . One end of the second arm 232 is rotatably connected to the link member 14 . The other end of the first arm 231 and the other end of the second arm 232 are rotatably connected to each other by a rotation support shaft 233 . The first arm 231 and the second arm 232 are arranged to have a V shape, and the first connecting bar 234 and the second connecting bar 235 are arranged to have an X shape between them. The first connecting bar 234 and the second connecting bar 235 are rotatably connected by a pin 236 at their intersections.

第１連結バー２３４及び第２連結バー２３５の一端部は、それぞれ第１アーム２３１及び第２アーム２３２に回動可能に接続され、第１連結バー２３４及び第２連結バー２３５の他端部は、自由端となっている。第１連結バー２３４及び第２連結バー２３５は、その他端部がその一端部よりも回動支軸２３３から離れる側に配置されている。ピン２３６と回動支軸２３３との間には、引張バネ２３７が張設されている。引張バネ２３７に付勢された第１連結バー２３４及び第２連結バー２３５の他端部は、第１アーム２３１及び第２アーム２３２に設けた第１当接部材２３８及び第２当接部材２３９にそれぞれ当接している。 One ends of the first connecting bar 234 and the second connecting bar 235 are rotatably connected to the first arm 231 and the second arm 232, respectively, and the other ends of the first connecting bar 234 and the second connecting bar 235 are , are free ends. The other ends of the first connecting bar 234 and the second connecting bar 235 are arranged farther from the pivot shaft 233 than the one ends thereof. A tension spring 237 is stretched between the pin 236 and the pivot shaft 233 . The other ends of the first connecting bar 234 and the second connecting bar 235 biased by the tension spring 237 are connected to the first contact member 238 and the second contact member 239 provided on the first arm 231 and the second arm 232 . are in contact with each other.

可動部材１２が固定部材１１に近づくように外力が作用すると、引張バネ２３７に抗して第２アーム２３２が第１アーム２３１に近づくように回動支軸２３３を支点として傾動し、リンク部材１４が第１回動軸線Ｘ１周りに傾動する。この際、第１当接部材２３８及び第２当接部材２３９に対する第１連結バー２３４及び第２連結バー２３５の接触位置が変化するので、梃子の原理により、可動部材１２が固定部材１１に近づくにつれてリンク部材１４に対する付勢力が弱まり、可動部材１２が固定部材１１から離れるにつれてリンク部材１４に対する付勢力が強まる。よって、外幌装置２１０がホームポジション状態にあるときに、外幌装置２１０に無用なバタつき動作が発生することを防止できる。また、可動部材１２が固定部材１１に対して近接する際には、擦り板２１に対する可動部材１２の摺動力を抑制でき、擦り板２１の摩耗低減に寄与できる。 When an external force acts to move the movable member 12 closer to the fixed member 11 , the second arm 232 tilts around the pivot shaft 233 so as to move closer to the first arm 231 against the tension spring 237 , and the link member 14 tilts about the first rotation axis X1. At this time, since the contact positions of the first connecting bar 234 and the second connecting bar 235 with respect to the first contact member 238 and the second contact member 239 change, the movable member 12 approaches the fixed member 11 according to the principle of leverage. As the movable member 12 moves away from the fixed member 11, the biasing force applied to the link member 14 increases. Therefore, when the outer hood device 210 is in the home position state, it is possible to prevent the outer hood device 210 from making an unnecessary fluttering motion. Moreover, when the movable member 12 approaches the fixed member 11 , the sliding force of the movable member 12 against the scraping plate 21 can be suppressed, and the abrasion of the scraping plate 21 can be reduced.
