Description
本発明は、スライドドアの閉動作時における挟み込みを検知する挟み込み検知センサに関する。 The present invention relates to an entrapment detection sensor that detects entrapment when a sliding door is closed.
従来、乗客が乗降する鉄道車両の乗降口には、鉄道車両の前後方向にスライドするスライドドアが設けられている。このような鉄道車両のスライドドアには、閉動作時に乗客の身体あるいは携行品が挟まれたことを検知するための構造が設けられている（例えば、特許文献１参照）。 BACKGROUND ART Conventionally, a slide door that slides in the front-rear direction of a railway vehicle is provided at an entrance/exit of a railway vehicle through which passengers get on and off. Such a slide door of a railroad vehicle is provided with a structure for detecting that a passenger's body or a carrying item is pinched during a closing operation (see, for example, Patent Document 1).
特許文献１に記載の戸挟み検出装置は、鉄道車両のスライドドアの閉方向先端の縁部に取り付けられる中空の戸先ゴム外部材と、戸先ゴム外部材の中空部に挿脱自在に収容された戸先ゴム内部材と、戸先ゴム内部材の先端部に固定された異物検出センサとしての圧電材とを有している。異物の挟み込みが発生すると、圧電材が戸先ゴム内部材の変形を電気信号に変換して出力し、この電気信号が増幅されて警報機に送られ、警報機が警報を発する。そして、この警報に応じて乗務員がスライドドアを開ける操作を行い、挟み込み状態を解消する。 The door pinch detection device described in Patent Document 1 is detachably housed in a hollow door outer rubber member attached to an edge portion of a sliding door of a railway vehicle at a front end in a closing direction, and a hollow portion of the door outer rubber member. And a piezoelectric material as a foreign matter detection sensor fixed to the tip of the inner-door-rubber member. When a foreign object is trapped, the piezoelectric material converts the deformation of the member inside the door tip rubber into an electric signal and outputs the electric signal. The electric signal is amplified and sent to an alarm device, and the alarm device issues an alarm. Then, in response to this warning, the crew member operates the slide door to eliminate the pinched state.
一方、本出願人は、例えば自動車のスライドドアによる挟み込みを検出するためのコードスイッチとして、特許文献２に記載のものを提案している。このコードスイッチは、複数の導体線を管状部材の内側に互いに離間して螺旋状に配置してなるコードスイッチ本体と、コードスイッチ本体の管状部材の弾性率よりも高い弾性率を有し、コードスイッチ本体に沿って配置された被取付部材と、コードスイッチ本体と被取付部材との間に介在し、コードスイッチ本体の管状部材の弾性率よりも低い弾性率を有する帯状の衝撃吸収部材とを有している。このコードスイッチでは、管状部材の径方向におけるあらゆる方向からの圧力を検知することができる。 On the other hand, the applicant of the present application has proposed a cord switch described in Patent Document 2 as a cord switch for detecting pinching by a sliding door of an automobile, for example. This cord switch has a cord switch body in which a plurality of conductor wires are spirally arranged inside a tubular member so as to be spaced apart from each other, and has an elastic modulus higher than that of the tubular member of the cord switch body. A mounted member arranged along the switch body, and a belt-shaped shock absorbing member interposed between the cord switch body and the mounted member and having a modulus of elasticity lower than that of the tubular member of the cord switch body. Have This cord switch can detect pressure from any direction in the radial direction of the tubular member.
特許文献１に記載の戸挟み検出装置は、スライドドアの閉動作時の移動方向に沿って圧電材が圧力を受けた場合には、挟み込みを的確に検出し得るが、閉動作時の移動方向に対して傾斜した方向から外力が作用した場合や、挟まれた異物が細い紐状のものである場合には、必ずしも圧電材が確実に反応しないおそれがある。このため、乗客が例えば紐状部材の先端部にカード類を収容するパスケース等の本体部材が連結された携行品を所持して鉄道車両から降車する際に、紐状部材がスライドドアに挟まれると、乗客が紐状部材を車室外側から引っ張っても警報が発せられず、紐状部材が挟まれたまま鉄道車両が発車してしまうおそれがある。 The door pinch detection device described in Patent Document 1 can accurately detect pinching when the piezoelectric material receives pressure along the moving direction of the sliding door during the closing motion, but the moving direction during the closing motion. When an external force is applied in a direction inclined with respect to the piezoelectric material, or when the sandwiched foreign matter is a thin string, the piezoelectric material may not necessarily react reliably. Therefore, for example, when a passenger carries a carrying item to which a main body member such as a pass case for accommodating cards is connected to the tip end of the string-shaped member and gets off the railway vehicle, the string-shaped member is caught between the sliding doors. Then, even if the passenger pulls the string-shaped member from the outside of the vehicle compartment, the alarm is not issued, and the railway vehicle may start leaving the string-shaped member sandwiched.
本発明者らは、このような態様の挟み込みが発生した場合にも挟み込みを検知できるよう、特許文献２に記載されたコードスイッチのコードスイッチ本体を複数本、戸先ゴムの空洞部内に収容することを考えた。しかし、この場合、空洞部の容積を、複数のコードスイッチ本体を収容するために必要な大きさよりも大きくし、適度な中空空間を確保しなければ、クッション性の低下を招来して乗客の身体の挟み込みが発生したときに大きな衝撃を乗客に与えてしまう。また、空洞部を大きくし過ぎると、空洞部内における各コードスイッチ本体の位置が定まらず、様々な態様の挟み込みを確実に検知することができない場合がある。 The inventors of the present invention house a plurality of cord switch main bodies of the cord switch described in Patent Document 2 in a hollow portion of a door tip rubber so that the trapping can be detected even when such trapping occurs. I thought about that. However, in this case, if the volume of the cavity is made larger than the size necessary to accommodate the plurality of cord switch bodies and a proper hollow space is not secured, the cushioning property will be deteriorated and the passenger's body will be deteriorated. Passengers will be given a great impact when the car is caught. Further, if the cavity is made too large, the position of each cord switch main body in the cavity may not be determined, and it may not be possible to reliably detect various types of pinching.
そこで、本発明は、スライドドアの閉動作時において、スライドドアの移動方向に対して傾斜した方向から外力が作用した場合でも、挟み込みを検知することが可能な挟み込み検知センサを提供することを目的とする。 Therefore, it is an object of the present invention to provide a trapping detection sensor capable of detecting trapping even when an external force is applied from a direction inclined with respect to the moving direction of the slide door during the closing operation of the slide door. And
本発明は、上記課題を解決することを目的として、スライドドアの閉動作時における挟み込みを検知する挟み込み検知センサであって、内部に空洞部を有し、前記スライドドアの閉移動方向の先端部に取り付けられる戸先ゴムと、前記空洞部に収容され、複数の導体線を管状の弾性体の内側に互いに離間して配置してなる複数の線状感圧部材と、を備え、前記戸先ゴムは、前記空洞部に前記複数の線状感圧部材をそれぞれ収容する複数の収容スペースを有し、前記複数の収容スペース間の前記線状感圧部材の移動が仕切り部によって規制されており、前記複数の収容スペースは、前記仕切り部によって隙間なく区画されている、挟み込み検知センサを提供する。 The present invention, for the purpose of solving the above problems, is a pinch detection sensor for detecting pinching during a closing operation of a slide door, which has a hollow portion inside thereof, and has a tip portion in the closing movement direction of the slide door. And a plurality of linear pressure-sensitive members housed in the hollow portion and having a plurality of conductor wires spaced apart from each other inside a tubular elastic body. The rubber has a plurality of accommodating spaces for accommodating the plurality of linear pressure-sensitive members, respectively, in the hollow portion, and movement of the linear pressure-sensitive members between the plurality of accommodating spaces is regulated by a partition section. The entrapment detection sensor is provided in which the plurality of accommodation spaces are partitioned by the partition portion without any gap.
本発明に係る挟み込み検知センサによれば、スライドドアの閉動作時において、スライドドアの移動方向に対して傾斜した方向から外力が作用した場合でも、挟み込みを検知することが可能となる。 According to the entrapment detection sensor of the present invention, it is possible to detect entrapment even when an external force is applied from a direction inclined with respect to the moving direction of the slide door during the closing operation of the slide door.

[First Embodiment]
FIG. 1 is an explanatory view showing the vicinity of an entrance/exit 10 of a railway vehicle 1 in which a trapping detection sensor 2 according to a first embodiment of the present invention is attached to left and right slide doors 11, 11, respectively.

The boarding/alighting direction is perpendicular to the traveling direction of the railway vehicle 1 and parallel to the thickness direction of the slide doors 11, 11. Each slide door 11 has a door plate 111 and a window glass 112 fitted in a window portion 111a of the door plate 111.
携行品９は、例えばカード類を収容するパスケース等の本体部材９１と、一方の端部が本体部材９１に連結された紐状部材９２とを有している。紐状部材９２の他方の端部は乗客８に把持されている。なお、紐状部材９２の他方の端部は、例えば乗客８のベルト等に吊り下げられる場合もある。 The carrying item 9 has a main body member 91 such as a pass case for accommodating cards and the like, and a string-like member 92 having one end connected to the main body member 91. The other end of the string-shaped member 92 is gripped by the passenger 8. The other end of the string-shaped member 92 may be hung on the belt of the passenger 8, for example.
スライドドア１１，１１は、車体１２に設けられた駆動装置１３，１３により、車体１２の前後方向にスライドして乗降口１０を開閉する。駆動装置１３，１３は、乗降口１０の上方に配置され、例えばリニアモータやボールねじ等の直動機構を有して構成されている。また、駆動装置１３，１３は、制御装置１４によって制御される。スライドドア１１，１１の移動範囲（前進端及び後退端の位置）は、駆動装置１３，１３に設けられた図略のストッパにより規定される。 The sliding doors 11, 11 are slid in the front-rear direction of the vehicle body 12 by the drive devices 13, 13 provided on the vehicle body 12 to open and close the entrance/exit 10. The drive devices 13 and 13 are disposed above the entrance/exit 10 and are configured to have a linear motion mechanism such as a linear motor or a ball screw. The drive devices 13 and 13 are controlled by the control device 14.

挟み込み検知センサ２は、互いに向かい合う左右のスライドドア１１，１１のそれぞれの端部に上下方向に沿って取り付けられており、スライドドア１１，１１の閉動作時において乗客８又はその携行品９が挟まれたとき、挟み込みを検知する。制御装置１４は、挟み込みが発生したことを示す信号を挟み込み検知センサ２から受けると、駆動装置１３，１３を制御してスライドドア１１，１１を開動作させる。なお、制御装置１４は、挟み込みが発生したことを示す信号を挟み込み検知センサ２から受けたとき、運転手や車掌等の乗員に警報を発するための警報信号を発するようにしてもよい。この場合には、乗員の操作によってスライドドア１１，１１が開かれる。 The entrapment detection sensor 2 is attached to each end of the left and right slide doors 11, 11 facing each other along the up-down direction, and the passenger 8 or his or her carrying item 9 is sandwiched when the slide doors 11, 11 are closed. When pinched, pinching is detected. When the control device 14 receives a signal indicating that entrapment has occurred from the entrapment detection sensor 2, the control device 14 controls the drive devices 13, 13 to open the slide doors 11, 11. It should be noted that the control device 14 may issue an alarm signal for issuing an alarm to an occupant such as a driver or a conductor when receiving a signal indicating that entrapment has occurred from the entrapment detection sensor 2. In this case, the slide doors 11, 11 are opened by the operation of the passenger.
図２は、挟み込みが発生していない自然状態における挟み込み検知センサ２を示す断面図である。図２では、挟み込み検知センサ２を乗降方向Ａ1及び閉方向Ａ2に対して平行な断面（長手方向直交断面）で示している。また、図２では、図面上側が鉄道車両１の車室外側（プラットフォーム７側）に、図面下側が車室内側にあたるものとする。 FIG. 2 is a cross-sectional view showing the pinch detection sensor 2 in a natural state in which no pinch has occurred. In FIG. 2, the entrapment detection sensor 2 is shown in a cross section (a cross section orthogonal to the longitudinal direction) parallel to the boarding/alighting direction A 1 and the closing direction A 2 . In FIG. 2, the upper side of the drawing corresponds to the outside of the passenger compartment of the railway vehicle 1 (the platform 7 side), and the lower side of the drawing corresponds to the inside of the passenger compartment.
挟み込み検知センサ２は、スライドドア１１の閉方向の先端部に取り付けられる戸先ゴム３と、複数の線状感圧部材４とを有している。戸先ゴム３は、内部に空洞部３０を有しており、この空洞部３０に複数の線状感圧部材４が収容されている。本実施の形態では、３つの線状感圧部材４が空洞部３０に収容されている。 The pinch detection sensor 2 has a door tip rubber 3 attached to the front end portion of the sliding door 11 in the closing direction, and a plurality of linear pressure sensitive members 4. The door tip rubber 3 has a hollow portion 30 therein, and a plurality of linear pressure sensitive members 4 are housed in the hollow portion 30. In this embodiment, the three linear pressure-sensitive members 4 are housed in the hollow portion 30.
戸板１１１には、戸先ゴム３を取り付けるための嵌合溝１１１ｂが上下方向に沿って形成されている。嵌合溝１１１ｂは、互いに対向する一対の突片１１１ｃ，１１１ｃ間の開口部１１１ｄを通じて閉方向に開放されている。 A fitting groove 111b for attaching the door tip rubber 3 is formed in the door plate 111 along the vertical direction. The fitting groove 111b is opened in the closing direction through the opening 111d between the pair of projecting pieces 111c and 111c facing each other.
戸先ゴム３は、図２に示す断面において矩形状の基体部３１と、空洞部３０よりも閉方向側で３つの線状感圧部材４を覆うカバー部３２と、戸板１１１の嵌合溝１１１ｂに嵌合される嵌合部３３と、基体部３１と嵌合部３３とを接続する接続部３４とを一体に有している。戸先ゴム３は、例えばウレタンゴム、ＥＰゴム、シリコーンゴム、スチレンブタンジエンゴム、クロロプレンゴム、オレフィン系又はスチレン系の熱可塑性エラストマ、あるいはウレタン樹脂等からなり、押し出し成型によって形成される。 The door tip rubber 3 has a rectangular base portion 31 in the cross section shown in FIG. 2, a cover portion 32 that covers the three linear pressure-sensitive members 4 on the closing direction side of the cavity portion 30, and a fitting groove of the door plate 111. The fitting portion 33 fitted to the 111b and the connecting portion 34 connecting the base portion 31 and the fitting portion 33 are integrally provided. The door end rubber 3 is made of, for example, urethane rubber, EP rubber, silicone rubber, styrene butanediene rubber, chloroprene rubber, olefin or styrene thermoplastic elastomer, or urethane resin, and is formed by extrusion molding.
基体部３１は、戸板１１１の一対の突片１１１ｃ，１１１ｃの閉方向側に配置され、カバー部３２との間に空洞部３０を形成する。カバー部３２は、乗降方向の中央部において閉方向に突出するアーチ状（半円状）に湾曲しており、両端部が基体部３１に連続している。接続部３４は、戸板１１１の開口部１１１ｄに配置されている。 The base portion 31 is disposed on the closing direction side of the pair of projecting pieces 111c, 111c of the door plate 111, and forms the cavity portion 30 with the cover portion 32. The cover portion 32 is curved in an arch shape (semi-circular shape) protruding in the closing direction at the center portion in the boarding/alighting direction, and both ends thereof are continuous with the base portion 31. The connection portion 34 is arranged in the opening portion 111d of the door plate 111.
また、戸先ゴム３は、空洞部３０を複数（本実施の形態では３つ）の収容スペース３０１〜３０３に仕切る仕切り部３５を基体部３１とカバー部３２との間に有している。以下、３つの収容スペース３０１〜３０３を、第１乃至第３の収容スペース３０１，３０２，３０３とする。第１乃至第３の収容スペース３０１，３０２，３０３は、乗降方向に並び、第１の収容スペース３０１が乗降方向の中央部に形成され、第２の収容スペース３０２が第１の収容スペース３０１よりも車室外側に、また第３の収容スペース３０３が第１の収容スペース３０１よりも車室内側に、それぞれ形成されている。 Further, the door tip rubber 3 has a partition part 35 for partitioning the hollow part 30 into a plurality of (three in the present embodiment) accommodation spaces 301 to 303 between the base part 31 and the cover part 32. Hereinafter, the three accommodation spaces 301 to 303 are referred to as first to third accommodation spaces 301, 302, 303. The 1st thru|or 3rd accommodation space 301,302,303 is located in a line in the boarding/alighting direction, the 1st housing space 301 is formed in the center part of a boarding/alighting direction, and the 2nd housing space 302 is more than the 1st housing space 301. Is formed outside the vehicle compartment, and the third accommodation space 303 is formed closer to the vehicle compartment than the first accommodation space 301.
仕切り部３５は、第１の収容スペース３０１と第２の収容スペース３０２とを仕切る第１の壁部３５１、及び第１の収容スペース３０１と第３の収容スペース３０３とを仕切る第２の壁部３５２からなる。第１の壁部３５１と第２の壁部３５２とは、互いに平行に、スライドドア１１の移動方向に沿って設けられている。また、第１の壁部３５１及び第２の壁部３５２は、一方の端部が基体部３１に連続し、他方の端部がカバー部３２に連続している。これにより、第１乃至第３の収容スペース３０１，３０２，３０３は、仕切り部３５によって隙間なく区画されている。３つの線状感圧部材４は、第１乃至第３の収容スペース３０１，３０２，３０３のそれぞれに収容されている。 The partition part 35 is a first wall part 351 for partitioning the first storage space 301 and the second storage space 302, and a second wall part for partitioning the first storage space 301 and the third storage space 303. 352. The first wall portion 351 and the second wall portion 352 are provided in parallel to each other along the moving direction of the slide door 11. Further, one end of the first wall portion 351 and the second wall portion 352 is continuous with the base portion 31, and the other end thereof is continuous with the cover portion 32. As a result, the first to third accommodation spaces 301, 302, 303 are partitioned by the partition 35 without any gap. The three linear pressure-sensitive members 4 are housed in each of the first to third housing spaces 301, 302, 303.
このように、本実施の形態では、戸先ゴム３が、空洞部３０に複数の線状感圧部材４をそれぞれ収容する第１乃至第３の収容スペース３０１，３０２，３０３を有し、第１乃至第３の収容スペース３０１，３０２，３０３間の線状感圧部材４の移動が仕切り部３５によって規制されている。 As described above, in the present embodiment, the door tip rubber 3 has the first to third accommodation spaces 301, 302, 303 for accommodating the plurality of linear pressure sensitive members 4 in the cavity 30, respectively. The movement of the linear pressure-sensitive member 4 between the first to third accommodation spaces 301, 302, 303 is restricted by the partition part 35.
図１に示す断面において第１の収容スペース３０１が占める面積のうち、線状感圧部材４が配置されている部分を除く中空空間の面積は、線状感圧部材４が配置された部分の面積よりも大きい。すなわち、第１の収容スペース３０１における中空空間の割合を空間率とすると、この空間率が５０％以上である。これにより、スライドドア１１，１１の閉動作時に戸先ゴム３が乗客８の身体に衝突したときの衝撃が緩和される。 In the area occupied by the first accommodating space 301 in the cross section shown in FIG. 1, the area of the hollow space excluding the portion where the linear pressure sensitive member 4 is arranged is the area of the portion where the linear pressure sensitive member 4 is arranged. Greater than area. That is, when the ratio of the hollow space in the first accommodation space 301 is defined as the space ratio, this space ratio is 50% or more. As a result, the impact of the door tip rubber 3 colliding with the body of the passenger 8 during the closing operation of the slide doors 11, 11 is mitigated.
本実施の形態では、第２及び第３の収容スペース３０２，３０３についても、空間率が５０％以上である。ただし、第２及び第３の収容スペース３０２，３０３の空間率は、第１の収容スペースの空間率よりも低い。第１の収容スペースの空間率の望ましい範囲は、５０％以上８０％以下であり、第２及び第３の収容スペース３０２，３０３の空間率の望ましい範囲は、４０％以上７０％以下である。空間率が低すぎるとクッション性が低下し、空間率が高すぎると線状感圧部材４の位置が適切な範囲に定まらないおそれがあるためである。 In the present embodiment, the space ratios of the second and third accommodation spaces 302 and 303 are also 50% or more. However, the space ratios of the second and third storage spaces 302 and 303 are lower than the space ratio of the first storage space. The desirable range of the space rate of the first accommodation space is 50% or more and 80% or less, and the desirable range of the space rate of the second and third accommodation spaces 302, 303 is 40% or more and 70% or less. This is because if the porosity is too low, the cushioning property is deteriorated, and if the porosity is too high, the position of the linear pressure sensitive member 4 may not be set in an appropriate range.
図３（ａ）は、線状感圧部材４を示す斜視図である。図３（ｂ）は、外力が加わらない自然状態における線状感圧部材４の断面図である。図３（ｃ）は、外力が加わった加圧状態における線状感圧部材４の断面図である。 FIG. 3A is a perspective view showing the linear pressure sensitive member 4. FIG. 3B is a cross-sectional view of the linear pressure sensitive member 4 in a natural state where no external force is applied. FIG. 3C is a cross-sectional view of the linear pressure sensitive member 4 in a pressed state in which an external force is applied.
線状感圧部材４は、管状の弾性体であるチューブ４１と、チューブ４１の内側に互いに離間して配置された複数の導体線４２とを有している。より詳細には、チューブ４１の内面に２本の導体線４２がその一部を露出させて螺旋状に保持されており、空間４０がチューブ４１の中心部に形成されている。チューブ４１は、例えばシリコーンゴムやエチレンプロピレンゴム等の絶縁性のゴム材料からなり、外力が加わることにより変形し、外力がなくなれば直ちに復元する弾性を有している。 The linear pressure-sensitive member 4 has a tube 41 that is a tubular elastic body, and a plurality of conductor wires 42 that are arranged inside the tube 41 and are separated from each other. More specifically, two conductor wires 42 are held in a spiral shape on the inner surface of the tube 41 with a part of the conductor wire 42 exposed, and a space 40 is formed at the center of the tube 41. The tube 41 is made of, for example, an insulating rubber material such as silicone rubber or ethylene propylene rubber, and has elasticity such that it is deformed when an external force is applied and is immediately restored when the external force disappears.
チューブ４１に外力が加わっていない自然状態では、複数の導体線４２が空間４０を挟んで互いに非接触に保持されている。また、チューブ４１に外力が加わると、チューブ４１が弾性変形して複数の導体線４２同士が接触する。それぞれの導体線４２は、複数の金属素線を撚り合わせた金属撚線４２１が、導電性被覆層４２２により被覆されている。この構造により、線状感圧部材４は、チューブ４１の径方向におけるあらゆる方向からの外力を感圧することが可能である。 In a natural state where no external force is applied to the tube 41, the plurality of conductor wires 42 are held in non-contact with each other across the space 40. When an external force is applied to the tube 41, the tube 41 elastically deforms and the plurality of conductor wires 42 come into contact with each other. In each conductor wire 42, a metal stranded wire 421 obtained by twisting a plurality of metal element wires is covered with a conductive coating layer 422. With this structure, the linear pressure sensitive member 4 can sense an external force from any direction in the radial direction of the tube 41.
図４は、線状感圧部材４によってスライドドア１１による挟み込みを検知するための電気回路５の一例を示す回路図である。この電気回路５は、線状感圧部材４の２本の導体線４２を含んで構成され、電源５１と、２本の導体線４２の端部同士を接続する接触検知用の抵抗器５２と、電源５１と直列に接続された電流計５３及び電流制限用の抵抗器５４とを有している。電流計５３は、例えばホールＩＣ等の電流センサ及び増幅器を有し、その検出信号が制御装置１４に出力される。 FIG. 4 is a circuit diagram showing an example of an electric circuit 5 for detecting pinching by the slide door 11 by the linear pressure-sensitive member 4. The electric circuit 5 is configured to include two conductor wires 42 of the linear pressure-sensitive member 4, and includes a power source 51 and a contact detection resistor 52 that connects end portions of the two conductor wires 42. , And an ammeter 53 and a current limiting resistor 54 connected in series with the power supply 51. The ammeter 53 has a current sensor such as a Hall IC and an amplifier, and the detection signal thereof is output to the control device 14.
上記のように構成された電気回路５において、線状感圧部材４が加圧されて導体線４２同士が接触すると、電流計５３によって検出される電流が変化する。制御装置１４は、電流計５３の検出信号の変化によってスライドドア１１による挟み込みが発生したことを認識し、駆動装置１３を停止又は反転動作させる。 In the electric circuit 5 configured as described above, when the linear pressure sensitive member 4 is pressed and the conductor wires 42 come into contact with each other, the current detected by the ammeter 53 changes. The control device 14 recognizes that the slide door 11 is pinched by the change in the detection signal of the ammeter 53, and stops or reverses the drive device 13.
なお、図４では、１本の線状感圧部材４に対応する電気回路５のみを示しているが、本実施の形態では、挟み込み検知センサ２が３本の線状感圧部材４を有しているので、それぞれの線状感圧部材４に対応して電気回路５が設けられており、それぞれの電気回路５の電流計５３の検出信号が制御装置１４に出力される。制御装置１４は、いずれかの線状感圧部材４が加圧されたことを認識したとき、駆動装置１３を停止又は反転動作させる。 Although only the electric circuit 5 corresponding to one linear pressure-sensitive member 4 is shown in FIG. 4, the pinch detection sensor 2 has three linear pressure-sensitive members 4 in the present embodiment. Therefore, the electric circuit 5 is provided corresponding to each linear pressure-sensitive member 4, and the detection signal of the ammeter 53 of each electric circuit 5 is output to the control device 14. When the control device 14 recognizes that any one of the linear pressure sensitive members 4 has been pressed, the control device 14 stops or inverts the drive device 13.
本実施の形態では、スライドドア１１の閉動作時の移動方向に対して傾斜した方向から外力が作用した場合でも挟み込みを確実に検知することを可能とするため、複数の線状感圧部材４を乗降方向において互いに異なる位置に配置している。つまり、複数の線状感圧部材４は、スライドドア１１，１１の移動方向及び戸先ゴム３の長手方向（上下方向）に対して交差する方向に並び、かつスライドドア１１の移動方向に重ならないように配置されている。以下、スライドドア１１，１１の移動方向及び戸先ゴム３の長手方向に対して交差する方向を並び方向という。 In the present embodiment, it is possible to reliably detect the pinching even when an external force is applied from a direction inclined with respect to the moving direction of the sliding door 11 during the closing operation. Are arranged at positions different from each other in the boarding/alighting direction. That is, the plurality of linear pressure-sensitive members 4 are arranged in a direction intersecting the moving direction of the slide doors 11, 11 and the longitudinal direction (vertical direction) of the door tip rubber 3 and overlap in the moving direction of the slide door 11. It is arranged not to become. Hereinafter, a direction that intersects the moving direction of the slide doors 11 and the longitudinal direction of the door tip rubber 3 is referred to as a line direction.
より具体的には、３つの線状感圧部材４のうち、第１の収容スペース３０１に収容された１つの線状感圧部材４が空洞部３０における並び方向の中央部に配置され、他の２つの線状感圧部材４が、第１の収容スペース３０１に収容された１つの線状感圧部材４の並び方向における一方側（車室外側）及び他方側（車室内側）に配置されている。一方側に配置された線状感圧部材４は、第２の収容スペース３０２に収容されており、他方側に配置された線状感圧部材４は、第３の収容スペース３０３に収容されている。 More specifically, among the three linear pressure-sensitive members 4, one linear pressure-sensitive member 4 accommodated in the first accommodating space 301 is arranged in the central portion of the cavity portion 30 in the arrangement direction, and The two linear pressure-sensitive members 4 are arranged on one side (outside of the vehicle compartment) and on the other side (inside of the vehicle compartment) in the arrangement direction of the one linear pressure-sensitive member 4 accommodated in the first accommodation space 301. Has been done. The linear pressure sensitive member 4 arranged on one side is accommodated in the second accommodating space 302, and the linear pressure sensitive member 4 arranged on the other side is accommodated in the third accommodating space 303. There is.
スライドドア１１の移動方向に沿ったスライドドア１１の幅方向における第１乃至第３の収容スペース３０１〜３０３の長さは、線状感圧部材４の直径よりも大きく、第１の収容スペース３０１に収容された線状感圧部材４は第１の収容スペース３０１内で、第２の収容スペース３０２に収容された線状感圧部材４は第２の収容スペース３０２内で、また第３の収容スペース３０３に収容された線状感圧部材４は第３の収容スペース３０３内で、それぞれスライドドア１１の幅方向に沿って移動可能である。 The length of the first to third accommodation spaces 301 to 303 in the width direction of the slide door 11 along the moving direction of the slide door 11 is larger than the diameter of the linear pressure sensitive member 4, and the first accommodation space 301. The linear pressure-sensitive member 4 accommodated in the first accommodating space 301, the linear pressure-sensitive member 4 accommodated in the second accommodating space 302 in the second accommodating space 302, and the third accommodating space The linear pressure-sensitive members 4 housed in the housing space 303 are movable in the third housing space 303 along the width direction of the slide door 11.
この戸先ゴム３の構造により、スライドドア１１，１１の閉動作時に乗客８の身体の一部がスライドドア１１，１１の間に挟まれても、第１乃至第３の収容スペース３０１〜３０３の空間により高められた戸先ゴム３のクッション性により、乗客８が感じる痛みが緩和される。特に、並び方向の中央部に位置する第１の収容スペース３０１は、第２及び第３の収容スペース３０２，３０３よりもスライドドア１１の幅方向の長さが長く、カバー部３２における閉方向の先端部が乗客８に衝突したときの衝撃が大きく緩和される。本実施の形態では、スライドドア１１の幅方向における第１の収容スペース３０１の長さが線状感圧部材４の直径の２倍以上である。 Due to the structure of the door tip rubber 3, even if a part of the body of the passenger 8 is sandwiched between the sliding doors 11 and 11 when the sliding doors 11 and 11 are closed, the first to third accommodation spaces 301 to 303. Due to the cushioning property of the rubber tip 3 enhanced by the space, the pain felt by the passenger 8 is relieved. In particular, the first accommodation space 301 located at the central portion in the arrangement direction has a longer length in the width direction of the slide door 11 than the second and third accommodation spaces 302 and 303, and the first accommodation space 301 in the closing direction in the cover portion 32 is The impact when the front end collides with the passenger 8 is greatly reduced. In the present embodiment, the length of the first accommodation space 301 in the width direction of the slide door 11 is twice or more the diameter of the linear pressure sensitive member 4.
図５は、スライドドア１１の閉動作時に、乗客８の身体の一部８１に戸先ゴム３のカバー部３２における閉方向の先端部が衝突し、第１の収容スペース３０１に収容された線状感圧部材４が加圧された状態を示している。第１の収容スペース３０１に収容された線状感圧部材４は、カバー部３２と基体部３１との間に挟まれ、チューブ４１が弾性変形して２本の導体線４２同士が接触する。 FIG. 5 illustrates a line accommodated in the first accommodating space 301 when the closing end of the cover 32 of the door tip rubber 3 collides with a part 81 of the body of the passenger 8 during the closing operation of the sliding door 11. The pressure-sensitive member 4 is shown in a pressed state. The linear pressure sensitive member 4 housed in the first housing space 301 is sandwiched between the cover portion 32 and the base body portion 31, and the tube 41 elastically deforms so that the two conductor wires 42 come into contact with each other.
図６は、車室外側に降車した乗客８の携行品９の紐状部材９２が左右のスライドドア１１，１１の間に挟まれ、本体部材９１が車室内側に取り残された状態で、鉄道車両１が矢印Ａ3で示す進行方向に走り出したときの状態を示している。 FIG. 6 shows a state in which the cord-shaped member 92 of the carry-on item 9 of the passenger 8 getting off outside the passenger compartment is sandwiched between the left and right slide doors 11 and the main body member 91 is left inside the passenger compartment. It shows a state when the vehicle 1 starts to run in the traveling direction indicated by arrow A 3 .
この状態では、左右のスライドドア１１，１１のうち進行方向後方側にあたるスライドドア１１に取り付けられた挟み込み検知センサ２の第２の収容スペース３０２に収容された線状感圧部材４が加圧され、２本の導体線４２同士が接触する。これにより挟み込みが検知される。つまり、本実施の形態に係る挟み込み検知センサ２では、紐状部材９２の太さが、左右のスライドドア１１，１１の間に挟まれただけでは挟み込みが検知されない寸法であっても、図６に示すようにスライドドア１１の閉方向に対して傾斜した方向から外力が作用することで、挟み込みを検知することが可能である。 In this state, the linear pressure-sensitive member 4 housed in the second housing space 302 of the pinch detection sensor 2 mounted on the slide door 11 on the rear side in the traveling direction of the left and right slide doors 11 is pressurized. The two conductor wires 42 contact each other. As a result, entrapment is detected. That is, in the entrapment detection sensor 2 according to the present embodiment, even if the string-shaped member 92 has a size such that entrapment cannot be detected only by being sandwiched between the left and right slide doors 11, 11, FIG. As shown in FIG. 5, the entrapment can be detected by the external force acting from the direction inclined with respect to the closing direction of the slide door 11.
なお、図示は省略しているが、紐状部材９２が左右のスライドドア１１，１１の間に挟まれた状態で鉄道車両１が走り出した際には、戸先ゴム３のカバー部３２が車室外側に引っ張られることで、第３の収容スペース３０３に収容された線状感圧部材４が加圧されて２本の導体線４２同士が接触する場合もある。また、第３の収容スペース３０３に収容された線状感圧部材４は、スライドドア１１，１１の閉動作中に乗客８が車室内側から車室外側に出ようとして戸先ゴム３にぶつかった場合にも加圧され得る。同様に、第２の収容スペース３０２に収容された線状感圧部材４は、スライドドア１１，１１の閉動作中に乗客８が車室外側から車室内側に入ろうとして戸先ゴム３にぶつかった場合にも加圧され得る。 Although illustration is omitted, when the railway vehicle 1 starts running with the string-shaped member 92 being sandwiched between the left and right slide doors 11, 11, the cover portion 32 of the door tip rubber 3 is used for the vehicle. The linear pressure-sensitive member 4 accommodated in the third accommodating space 303 may be pressurized by being pulled to the outdoor side, and the two conductor wires 42 may come into contact with each other. The linear pressure-sensitive member 4 housed in the third housing space 303 collides with the rubber tip 3 while the slide doors 11 and 11 are being closed and the passenger 8 tries to move out of the passenger compartment to the outside of the passenger compartment. It can also be pressurized. Similarly, the linear pressure-sensitive member 4 accommodated in the second accommodating space 302 collides with the rubber tip 3 while the passenger 8 tries to enter from the outside of the vehicle interior to the inside of the vehicle interior during the closing operation of the slide doors 11, 11. It can also be pressurized.
鉄道車両１が発車した後に挟み込み検知センサ２によって挟み込みが検知された場合には、警報を受けた運転者の手動操作により、もしくは自動運転の場合には自動的に、鉄道車両１を速やかに停止させてスライドドア１１，１１が開動作される。 When the trapping detection sensor 2 detects the trapping after the railway vehicle 1 has started, the railway vehicle 1 is promptly stopped by a manual operation of a driver who receives an alarm or automatically in the case of automatic driving. Then, the slide doors 11, 11 are opened.
（第１の実施の形態の効果）
以上説明した第１の実施の形態によれば、下記（１）〜（３）の作用及び効果を得ることができる。
(Effect of the first embodiment)
According to the first embodiment described above, the following actions (1) to (3) can be obtained.
（１）空洞部３０が仕切り部３５によって第１乃至第３の収容スペース３０１〜３０３に区画されているので、戸先ゴム３の空洞部３０内における複数の線状感圧部材４の移動を制限し、複数の線状感圧部材４を各方向からの外力を受ける位置にそれぞれ定位させることができる。これにより、スライドドア１１の閉動作時の移動方向に対して傾斜した方向から外力が作用した場合でも、挟み込みを検知することが可能となる。 (1) Since the cavity portion 30 is divided into the first to third accommodation spaces 301 to 303 by the partition portion 35, the movement of the plurality of linear pressure sensitive members 4 in the cavity portion 30 of the door tip rubber 3 is prevented. It is possible to limit the positions of the plurality of linear pressure-sensitive members 4 and to position the linear pressure-sensitive members 4 at positions that receive external force from each direction. Thereby, even when an external force is applied from a direction inclined with respect to the moving direction of the sliding door 11 during the closing operation, it is possible to detect the entrapment.
（２）複数の線状感圧部材４は、スライドドア１１の移動方向には重ならず、並び方向において互いに異なる位置に配置されているので、挟み込み検知センサ２によって圧力を検知可能な角度範囲が拡がる。また、本実施の形態では、発生頻度が高いスライドドア１１の閉方向の挟み込みを並び方向の中央部に配置された線状感圧部材４によって検知し、スライドドア１１の閉方向に対して傾斜した方向の挟み込みを他の２つの線状感圧部材４によって検知するので、様々な態様の挟み込みを確実に検知することが可能である。 (2) Since the plurality of linear pressure-sensitive members 4 do not overlap with each other in the moving direction of the slide door 11 and are arranged at positions different from each other in the arranging direction, the angle range in which the trapping detection sensor 2 can detect the pressure. Spreads. Further, in the present embodiment, the pinch in the closing direction of the sliding door 11 that frequently occurs is detected by the linear pressure-sensitive member 4 arranged in the central portion in the arranging direction, and tilted with respect to the closing direction of the sliding door 11. Since the other two linear pressure-sensitive members 4 detect the entrapment in the predetermined direction, it is possible to reliably detect the entrapment in various modes.
（３）第１乃至第３の収容スペース３０１，３０２，３０３は、仕切り部３５によって隙間なく区画されているので、戸先ゴム３がどのように変形しても、第１乃至第３の収容スペース３０１，３０２，３０３間を線状感圧部材４が移動してしまうことがなく、複数の線状感圧部材４を適切に配置することができる。 (3) Since the first to third storage spaces 301, 302, 303 are partitioned by the partition portion 35 without any gap, no matter how the door rubber 3 is deformed, the first to third storage spaces are stored. The linear pressure-sensitive members 4 do not move between the spaces 301, 302, 303, and the plurality of linear pressure-sensitive members 4 can be appropriately arranged.
［第２の実施の形態］
次に、図７を参照して本発明の第２の実施の形態について説明する。図７は、第２の実施の形態に係る挟み込み検知センサ２Ａを示す断面図である。本実施の形態では、戸先ゴム３の基体部３１が、並び方向の中央部で閉方向側（カバー部３２側）に突出する半円状の突起３１１を有している。この突起３１１は、第１乃至第３の収容スペース３０１〜３０３に跨って形成されており、第１の収容スペース３０１に向かって最も大きく張り出している。
[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a sectional view showing the entrapment detection sensor 2A according to the second embodiment. In the present embodiment, the base portion 31 of the door tip rubber 3 has a semicircular protrusion 311 that protrudes toward the closing direction side (cover portion 32 side) at the central portion in the arrangement direction. The protrusion 311 is formed so as to straddle the first to third accommodation spaces 301 to 303, and projects the largest toward the first accommodation space 301.
この第２の実施の形態に係る挟み込み検知センサ２Ａによれば、第１の実施の形態に比較して、第１の収容スペース３０１の長さが短くなるので、カバー部３２の変形量が少なくても第１の収容スペース３０１に収容された線状感圧部材４の２本の導体線４２が接触し、比較的小さな外力であっても挟み込みを検知することが可能となる。また、スライドドア１１の閉方向に対して傾斜した方向から外力が加わった場合には、第２の収容スペース３０２又は第３の収容スペース３０３に収容された線状感圧部材４が突起３１１に押し付けられ、２本の導体線４２が接触するので、この方向の挟み込みに対しても、比較的小さな外力で挟み込みを検知することが可能となる。 According to the entrapment detection sensor 2A according to the second embodiment, the length of the first accommodation space 301 is shorter than that in the first embodiment, so that the deformation amount of the cover portion 32 is small. However, the two conductor wires 42 of the linear pressure-sensitive member 4 accommodated in the first accommodating space 301 come into contact with each other, and the pinch can be detected even with a relatively small external force. When an external force is applied from a direction inclined with respect to the closing direction of the slide door 11, the linear pressure-sensitive member 4 housed in the second housing space 302 or the third housing space 303 is attached to the protrusion 311. Since the two conductor wires 42 are pressed against each other and come into contact with each other, it is possible to detect the pinching in this direction with a relatively small external force.
［第３の実施の形態］
図８は、第３の実施の形態に係る挟み込み検知センサ２Ｂを示す断面図である。この検知スイッチ２Ｂは、第２の実施の形態に係る検知スイッチ２Ａと同様に、基体部３１に並び方向の中央部で閉方向側に突出する突起３１１が設けられているが、この突起３１１の形状が第２の実施の形態とは異なり、台形状に形成されている。突起３１１は、第１の収容スペース３０１における頂面から遠ざかるほど並び方向の幅が広くなり、第２及び第３の収容スペース３０２，３０３における両側面の間の距離が長くなる。また、挟み込み検知センサ２Ｂでは、第１の壁部３５１及び第２の壁部３５２が、突起３１１の頂面と両側面との間の角部から、スライドドア１１の移動方向に対して互いに離間するように傾斜して延在している。
[Third Embodiment]
FIG. 8 is a sectional view showing the entrapment detection sensor 2B according to the third embodiment. Similar to the detection switch 2A according to the second embodiment, the detection switch 2B is provided with a protrusion 311 that protrudes toward the closing direction at the central portion of the base portion 31 in the alignment direction. Unlike the second embodiment, the shape is trapezoidal. The width of the protrusion 311 in the arrangement direction becomes wider as it goes away from the top surface of the first accommodation space 301, and the distance between both side surfaces of the second and third accommodation spaces 302, 303 becomes longer. In the entrapment detection sensor 2B, the first wall portion 351 and the second wall portion 352 are separated from each other in the moving direction of the slide door 11 from the corner between the top surface and both side surfaces of the protrusion 311. It extends so as to be inclined.
この第３の実施の形態によっても、第２の実施の形態と同様に、比較的小さな外力であっても挟み込みを検知することが可能となる。 According to the third embodiment as well, similar to the second embodiment, it becomes possible to detect entrapment even with a relatively small external force.

One linear pressure sensitive member 4 is housed in each.
本実施の形態によっても、スライドドア１１の閉動作時の移動方向に対して傾斜した方向から外力が作用する挟み込みを検知することが可能となる。また、線状感圧部材４の本数を削減できるので、第１乃至第３の実施の形態に比較して、低コスト化を図ることが可能となる。 Also according to the present embodiment, it becomes possible to detect the entrapment in which the external force acts from the direction inclined with respect to the moving direction of the sliding door 11 during the closing operation. Moreover, since the number of linear pressure-sensitive members 4 can be reduced, cost reduction can be achieved as compared with the first to third embodiments.

次に、図１４を参照して本発明の第９の実施の形態について説明する。第１乃至第８の実施の形態では、左右のスライドドア１１，１１に同じ構造の挟み込み検知センサを用いること前提として説明したが、本実施の形態では、左右のスライドドア１１，１１のうち一方のスライドドア１１に取り付けられる挟み込み検知センサと、他方のスライドドア１１に取り付けられる挟み込み検知センサの構造が異なっている。以下、一方のスライドドア１１に取り付けられる挟み込み検知センサを一方側挟み込み検知センサ２Ｈとし、他方のスライドドア１１に取り付けられる挟み込み検知センサを他方側挟み込み検知センサ２Ｉとして説明する。
[Ninth Embodiment]
Next, a ninth embodiment of the present invention will be described with reference to FIG. In the first to eighth embodiments, description has been made on the assumption that the sandwiching detection sensor having the same structure is used for the left and right slide doors 11, 11, but in the present embodiment, one of the left and right slide doors 11, 11 is used. The structure of the pinch detection sensor attached to the slide door 11 and the structure of the pinch detection sensor attached to the other slide door 11 are different. Hereinafter, the pinch detection sensor attached to one slide door 11 will be referred to as the one side pinch detection sensor 2H, and the pinch detection sensor attached to the other slide door 11 will be described as the other side pinch detection sensor 2I.
一方側挟み込み検知センサ２Ｈは、第８の実施の形態に係る挟み込み検知センサ２Ｇのカバー部３２にさらに外方突起３２２を設けたものである。外方突起２３２は、カバー部３２の並び方向中央部から他方側挟み込み検知センサ２Ｉに向かって、空洞部３０とは反対側に突出している。 The one side entrapment detection sensor 2H is the entrapment detection sensor 2G according to the eighth embodiment in which a cover portion 32 is further provided with an outer protrusion 322. The outer protrusion 232 projects from the central portion of the cover portion 32 in the arrangement direction toward the other side pinch detection sensor 2I on the side opposite to the cavity portion 30.
他方側挟み込み検知センサ２Ｉは、第４の実施の形態に係る挟み込み検知センサ２Ｃを変形したものであり、カバー部３２の並び方向中央部に、一方側挟み込み検知センサ２Ｈの外方突起３２２が嵌合する嵌合凹部３００が凹設されている。嵌合凹部３００は、カバー部３２から仕切り部３５３に至る範囲に形成されている。なお、他方側挟み込み検知センサ２Ｉの戸先ゴム３において空洞部３０を第１の収容スペース３０４と第２の収容スペース３０５とに区画する仕切り部３５３の並び方向の厚みは、少なくとも閉方向側の端部において、嵌合凹部３００の並び方向の幅よりも厚く形成されている。 The other side pinch detection sensor 2I is a modification of the pinch detection sensor 2C according to the fourth embodiment, and the outer protrusion 322 of the one side pinch detection sensor 2H is fitted to the central portion of the cover portion 32 in the arrangement direction. A fitting recess 300 to be fitted is provided. The fitting recess 300 is formed in a range from the cover 32 to the partition 353. In addition, in the door tip rubber 3 of the other side pinch detection sensor 2I, the partitioning portion 353 that divides the hollow portion 30 into the first housing space 304 and the second housing space 305 is at least the thickness in the closing direction side. The end portion is formed to be thicker than the width of the fitting recess 300 in the arrangement direction.
この第９の実施の形態によれば、左右のスライドドア１１，１１に乗客８あるいはその携行品９が挟まれたとき、挟み込みによる圧力が一方側挟み込み検知センサ２Ｈの外方突起３２２から第１の収容スペース３０１に収容された線状感圧部材４に伝わりやすくなり、挟み込みを確実に検知することができる。また、一方側挟み込み検知センサ２Ｈの外方突起３２２が他方側挟み込み検知センサ２Ｉの嵌合凹部３００に嵌合することにより、鉄道車両１の車内の気密性が向上する他、スライドドア１１，１１のガタつきも抑制される。 According to the ninth embodiment, when the passenger 8 or the carried article 9 is sandwiched between the left and right slide doors 11, 11, the pressure due to the entrapment is applied to the first protrusion from the outer protrusion 322 of the one-side entrapment detection sensor 2H. The linear pressure-sensitive member 4 housed in the housing space 301 can be easily transmitted, and the pinch can be reliably detected. Further, by fitting the outer protrusion 322 of the one-side entrapment detection sensor 2H into the fitting recess 300 of the other-side entrapment detection sensor 2I, the airtightness of the inside of the railway vehicle 1 is improved, and the slide doors 11, 11 are provided. Rattling is also suppressed.
