Description

本発明は、鉄道車両の乗降扉に設置される戸先ゴムであって、乗降扉に乗客または物が挟まれたこと、または挟まれた物が引き抜かれることを検知するための戸先ゴムに関するものである。
例えば、鉄道車両の乗降扉に設置した戸先ゴム内に、密閉された空気室を設け、その空気室の上端にビニールチューブを連通し、そのビニールチューブの反対側に空気圧センサを連通する。乗降扉に人や物が挟まれたり、挟まれた物を引き抜こうとすると、戸先ゴムが圧迫され、戸先ゴムの空気室内の空気圧が上昇する。その空気圧の上昇が、ビニールチューブを伝わって、空気圧センサに届き、空気圧センサの接点が接触する。これにより電気信号が発せられ戸挟みが検知される。本発明は、このような戸挟み検知に用いられる戸先ゴムである。 The present invention relates to a door rubber installed on a passenger door of a railway vehicle, and relates to a door rubber for detecting that a passenger or an object is caught in the passenger door, or that the inserted object is pulled out. Is.
For example, a sealed air chamber is provided in a door rubber installed on a passenger door of a railway vehicle, a vinyl tube is communicated with the upper end of the air chamber, and an air pressure sensor is communicated with the opposite side of the vinyl tube. When a person or an object is caught in the passenger door or when an object is pulled out, the door rubber is compressed, and the air pressure of the air chamber of the door rubber increases. The increase in air pressure is transmitted through the vinyl tube and reaches the air pressure sensor, and the contact of the air pressure sensor contacts. As a result, an electrical signal is generated to detect the door pinching. The present invention is a door rubber used for such door pinching detection.

従来の戸挟み検知用戸先ゴムにおいては、戸先ゴム内に円形状または楕円形状の空気室が設けられていた。   In the conventional door-end rubber for detecting door pinching, a circular or elliptical air chamber is provided in the door-end rubber.

また、下記の特許文献１には、光ファイバーを戸先ゴム内に通し、車外側へ引っ張られた時だけ変形するように工夫して伝達光量の変化を検出し、車外側からの戸挟みを検知する戸先ゴムが記載されている。
特開平０９−１０９８８３号公報 Further, in Patent Document 1 below, an optical fiber is passed through a door rubber and devised so as to be deformed only when pulled to the outside of the vehicle to detect a change in the amount of transmitted light and to detect a pinch from the outside of the vehicle. Toe rubber is described.
Japanese Patent Application Laid-Open No. 09-109883

上記のように、従来の戸挟み検知用戸先ゴム内に設けられる空気室は、円形状または楕円形状といった、戸先ゴム中心線に対して、線対称の形状を有していたため、車外のプラットホーム上の人が、体の一部または衣服、鞄等を乗降扉に挟まれ、車外側（プラットホーム側）に引っ張る場合も、車内の人が内側に引っ張る場合も同じ感度で戸挟みが検知される。その結果、駆け込み乗車をした車内の人が、乗降扉に挟まれた衣服や鞄を車内側に引き抜いただけで、戸挟みが検知されて、乗降扉が再開閉し、列車の定時運行に影響を与える恐れがあった。
また、上記の特許文献１に記載された、光ファイバーを使用して車外側からの戸挟みを検知する方法は、光量を検知する装置が別に必要になるため、コストが高く、また、多くの設置スペースが必要になるという問題があった。
本発明は、戸挟み検知に使用する戸先ゴムであって、特別なコストや仮設スペースの必要なしに簡易な構成で戸挟みを検知することができる鉄道車両の乗降扉用戸先ゴムの提供を目的とする。
また、本発明は、乗降扉に挟まれた物が車外のプラットホーム側から引っ張られた時の戸挟みの検知感度を敏感にし、乗降扉に挟まれた物が車内側から引っ張られた時の戸挟みの検知感度を鈍感にする（検知感度に指向性を持たせる）ことを可能とする鉄道車両の乗降扉用戸先ゴムの提供を目的とする。
また、本発明は、乗降扉に物が挟まれた場合の戸挟みの検知感度を敏感にする鉄道車両の乗降扉用戸先ゴムの提供を目的とする。 As described above, the air chamber provided in the conventional door clamp detection door rubber has a symmetrical shape with respect to the door rubber center line such as a circular shape or an elliptical shape. When a person on the platform pulls a body part or clothes, bag, etc. between the entrance and exit doors and pulls it to the outside (platform side) of the vehicle, or the person inside the vehicle pulls it inside, the door is detected with the same sensitivity. The As a result, passengers who rushed in and pulled out clothes and bags caught between the entrance and exit doors, the door was detected, and the entrance and exit doors were reopened and closed, affecting the scheduled train operation. There was a fear of giving.
In addition, the method of detecting door pinching from the outside of a vehicle using an optical fiber described in Patent Document 1 requires a separate device for detecting the amount of light, which is expensive and requires many installations. There was a problem of needing space.
The present invention provides a door-end rubber used for door-slip detection, and provides a door-end rubber for a passenger door of a railway vehicle that can detect the door-slip with a simple configuration without requiring a special cost or a temporary space. With the goal.
In addition, the present invention makes the door pinch detection sensitivity sensitive when an object sandwiched between the passenger doors is pulled from the platform outside the vehicle, and the door when the objects sandwiched between the passenger doors are pulled from the inside of the vehicle. It is an object of the present invention to provide a doorway rubber for a passenger door of a railway vehicle that makes it possible to make the pinch detection sensitivity insensitive (make the detection sensitivity have directivity).
Another object of the present invention is to provide a doorway rubber for a passenger door of a railway vehicle that makes the detection sensitivity of the door pinching when an object is caught between the passenger doors sensitive.

それぞれの戸先ゴムに設けられた半円状の空気室の直線部分は、その円弧部分が対向するように該乗降扉の開閉方向に対してそれぞれ異なった方向に傾いており、かつ、それぞれの空気室の円弧部分が該戸先ゴムの先端部の近傍に位置し、さらに、該円弧部分が車内側を向くように配置される。
なお、上記戸先ゴムの先端部は、乗降扉が閉じるときに一対の戸先ゴムが互いに接触する部分を言う。 In order to solve the above problems, the present invention solves the above problems as follows.
(1) A door rubber for a passenger door of a railway vehicle, which is a door rubber for a door pinching detection device that is installed at a door tip of a passenger door of a railway vehicle and is made of an elastic member, is provided.

（１）本発明の鉄道車両の乗降扉用戸先ゴムには、該戸先ゴムをその長手方向に直交する平面で切ったときの断面形状が半円状である空気室が設けられる。また、上記空気室は圧力センサが設けられた空間に連通している。本発明の鉄道車両の乗降扉用戸先ゴムによれば、例えば、光ファイバー等光量を検知するための手段を必要としないため、特別なコストや設置スペースの必要なしに、簡易な構成で戸挟みを検知することができる。
（２）本発明の鉄道車両の乗降扉用戸先ゴムに設けられる該半円形状の空気室は戸先ゴムの車内側に配置され、戸先ゴムの車外側は中実である。従って、乗降扉に挟まれた物を車外のプラットホーム側から引っ張ると、戸先ゴムの車内側が圧迫されて、該半円形状の空気室が変形し、空気室内の圧力が上昇し、圧力センサを通じて戸挟みが検知される。本発明の鉄道車両の乗降扉用戸先ゴムによれば、乗降扉に挟まれた物を車外のプラットホーム側から引っ張った場合の戸挟みの検知感度を敏感にすることができる。
一方、乗降扉に挟まれた物を車内側から引っ張ると、戸先ゴムの車外側が圧迫されるが、戸先ゴムの車外側は中実であるので、空気室は少ししか変形せず、戸挟みが検知され難くなる。すなわち、本発明の鉄道車両の乗降扉用戸先ゴムによれば、乗降扉に挟まれた物を車内側から引っ張った場合の戸挟みの検知感度を鈍感にすることができる。
上記のように、本発明の鉄道車両の乗降扉用戸先ゴムによれば、戸挟みの検知感度に指向性を持たせることができる。その結果、危険性が高い車外からの物の引っ張りに対しては、敏感に戸挟みを検知して事故を防止することができ、危険性の低い車内からの物の引っ張りに対しては、戸挟みを検知しないで定時運行を維持することができる。
（３）本発明の鉄道車両の乗降扉用戸先ゴムは、乗降扉が閉じるときに接触する一対のゴムからなり、該一対の戸先ゴムに設けられた断面形状が半円状の空気室は、その円弧部分が対向するように、その直線部分が乗降扉の開閉方向に対してそれぞれ異なった方向に傾いており、かつ、それぞれの空気室の円弧部分が該戸先ゴムの先端部の近傍に位置し、さらに、該円弧部分が車内側を向くように配置される。
例えば、該一対の戸先ゴムに設けられた空気室は車内側に４５°回転した位置に配置される。
上記構成を採る鉄道車両の乗降扉用戸先ゴムによれば、乗降扉に物が挟まれた場合に、乗降扉に挟まれた物が、戸先ゴムの先端部を圧迫して、該先端部の近傍に上記円弧部分が位置するように配置された空気室３の空気圧を敏感に上昇させ、圧力センサに戸挟みを検知させる。その結果、乗降扉に物が挟まれた場合の戸挟みの検知感度を敏感にすることができる。 According to the present invention, the following effects can be obtained.
(1) The doorway rubber for the passenger door of the railway vehicle of the present invention is provided with an air chamber having a semicircular cross-section when the doorend rubber is cut along a plane perpendicular to the longitudinal direction. The air chamber communicates with a space provided with a pressure sensor. According to the door rubber for a passenger door of a railway vehicle of the present invention, for example, a means for detecting the amount of light such as an optical fiber is not required. Can be detected.
(2) The semicircular air chamber provided in the doorway rubber for the passenger door of the railway vehicle of the present invention is disposed inside the door rubber, and the outside of the door rubber is solid. Therefore, when an object sandwiched between the passenger doors is pulled from the platform side outside the vehicle, the inside of the door rubber is compressed, the semicircular air chamber is deformed, the pressure in the air chamber rises, and the pressure sensor A door pinch is detected. According to the door rubber for a passenger door of a railway vehicle according to the present invention, it is possible to make the detection sensitivity of the door pinch when an object sandwiched between the passenger doors is pulled from the platform side outside the vehicle.
On the other hand, when the object sandwiched between the passenger doors is pulled from the inside of the vehicle, the outside of the door rubber is compressed, but the outside of the door rubber is solid, so the air chamber is only slightly deformed, It becomes difficult to detect the door pinching. That is, according to the door-end rubber for the passenger door of the railway vehicle of the present invention, the detection sensitivity of the door pinching when an object pinched by the passenger door is pulled from the inside of the vehicle can be made insensitive.
As described above, according to the doorway rubber for a passenger door of a railway vehicle according to the present invention, it is possible to give directivity to the detection sensitivity of the door pinching. As a result, it is possible to prevent accidents by sensitively detecting door pinching when pulling objects from outside the vehicle with high risk. Scheduled operation can be maintained without detecting pinching.
(3) The doorway rubber for a passenger door of a railway vehicle according to the present invention is made of a pair of rubbers that come into contact when the passenger door closes, and an air chamber having a semicircular cross section provided in the pair of doorend rubbers. The linear portions are inclined in different directions with respect to the opening / closing direction of the passenger door so that the circular arc portions face each other, and the circular arc portions of the respective air chambers are arranged at the tip of the door rubber. It is located in the vicinity and is further arranged so that the arc portion faces the vehicle interior.
For example, the air chamber provided in the pair of door rubbers is disposed at a position rotated 45 ° toward the inside of the vehicle.
According to the doorway rubber for a passenger door of a railway vehicle adopting the above-described configuration, when an object is sandwiched between the passenger doors, the object sandwiched between the passenger doors compresses the front end portion of the door rubber, The air pressure of the air chamber 3 arranged so that the circular arc portion is positioned in the vicinity of the portion is raised sensitively, and the pressure sensor detects the door pinching. As a result, it is possible to make the detection sensitivity of the pinch when the object is pinched between the passenger doors sensitive.

本発明の鉄道車両の乗降扉用戸先ゴムは、鉄道車両の乗降扉の戸先に設置され、弾性部材から構成される戸挟み検知装置用戸先ゴムであって、該戸先ゴムには空気室が設けられ、該戸先ゴムをその長手方向に直交する平面で切ったときの該空気室の断面形状は半円状であって、該半円形状の空気室は戸先ゴムの車内側に配置され、戸先ゴムの車外側は中実であり、前記空気室は圧力センサが設けられた空間に連通している。このような構成を採る本発明の鉄道車両の乗降扉用戸先ゴムによれば、コストアップや設置スペースの増加なしに、戸先ゴムの感度に指向性を持たせるとともに、車外から物が引っ張られた場合に該空気室の空気圧を敏感に上昇させることができる。従って、車外から物が引っ張られた場合の戸挟みを確実に検知し、かつ定時運行を確保することが可能となる。なお、戸先ゴムの感度に指向性を持たせるとは、乗降扉に挟まれた物が車外側から引っ張られた時に、戸先ゴムに設けられた空気室内の空気圧が上昇し、車内側から引っ張られた時に、該空気室の空気圧が上昇しないことをいう。   A door rubber for a passenger door of a railway vehicle according to the present invention is a door rubber for a door pinching detection device that is installed on a door door of a passenger door of a railway vehicle and is composed of an elastic member. An air chamber is provided, and the cross-sectional shape of the air chamber when the door rubber is cut by a plane perpendicular to the longitudinal direction thereof is a semicircular shape, and the semicircular air chamber is a vehicle made of a door rubber. Arranged inside, the outside of the door rubber is solid, and the air chamber communicates with a space provided with a pressure sensor. According to the door rubber for a passenger door of a railway vehicle of the present invention having such a configuration, the sensitivity of the door rubber is given directivity and an object is pulled from the outside of the vehicle without increasing the cost and increasing the installation space. The air pressure of the air chamber can be raised sensitively. Therefore, it is possible to reliably detect the door pinching when an object is pulled from the outside of the vehicle and to ensure a scheduled operation. Note that the directionality of the sensitivity of the door rubber means that when an object sandwiched between the passenger doors is pulled from the outside of the vehicle, the air pressure in the air chamber provided in the door rubber increases, This means that the air pressure of the air chamber does not increase when pulled.

図１は、鉄道車両用の乗降扉戸挟み検知装置の構成図の一例である。鉄道車両用の乗降扉戸挟み検知装置は、乗降扉１の戸先部に設置した戸先ゴム２内に密閉された空気室３を設け、その空気室３の上端にビニールチューブ４の一端を連通し、そのビニールチューブ４の他端を空気圧センサ５に連通する。
乗降扉に人や物が挟まれたり、人が、挟まれた物を引き抜こうとすると、戸先ゴム２が圧迫され、戸先ゴム２に設けられた空気室３内の空気圧が上昇する。空気室３内の空気圧の上昇が、ビニールチューブ４を伝わって、空気圧センサ５に届き、空気圧センサの接点が接触することによって、電気信号が発せられて、例えばランプ６が発光し、戸挟みが検知される。また、空気室３の上端と下端に芯ゴム７を詰め込み、通常の戸閉操作の際は、芯ゴム７が戸閉力を受けて、空気室３の圧迫を無くし、誤検知を防止する。 FIG. 1 is an example of a configuration diagram of a passenger door pinch detection device for a railway vehicle. The railroad vehicle entrance / exit door pinching detection device is provided with an air chamber 3 sealed in a door-end rubber 2 installed at the door-end portion of the entrance / exit door 1, and one end of a vinyl tube 4 is provided at the upper end of the air chamber 3. The other end of the vinyl tube 4 communicates with the air pressure sensor 5.
When a person or an object is caught between the passenger doors or a person tries to pull out the object, the door rubber 2 is compressed, and the air pressure in the air chamber 3 provided in the door rubber 2 increases. An increase in the air pressure in the air chamber 3 is transmitted through the vinyl tube 4 to the air pressure sensor 5 and contacts with the air pressure sensor contact, so that an electric signal is generated, for example, the lamp 6 emits light, and the door clamp is Detected. Further, the upper and lower ends of the air chamber 3 are filled with the core rubber 7, and the core rubber 7 receives the door closing force during the normal door closing operation, thereby eliminating the pressure of the air chamber 3 and preventing erroneous detection.

次に、図１に示すように構成された鉄道車両用の乗降扉戸挟み検知装置に備えられる、鉄道車両の乗降扉用戸先ゴムの動作について、図２及び図３を参照して説明する。   Next, the operation of the doorway rubber for the entrance / exit of the railway vehicle provided in the entrance / exit door pinch detection device for the railway vehicle configured as shown in FIG. 1 will be described with reference to FIGS. 2 and 3. .

図２は、本発明の実施例１を説明する図である。図２中には、戸先ゴムをその長手方向に直交する平面で切ったときの断面が示され、図２中の２ａは、感度に指向性を持たせた戸先ゴムである。戸先ゴム２ａ内に設けられた空気室３の断面形状は半円状（楕円形状であってもよい) であって、空気室３は戸先ゴム２ａの車内側に配置され、戸先ゴム２ａの車外側は中実である。
図２（Ａ）は、乗降扉１に挟まれた介在物８がプラットホーム側（車外側）から引っ張られた場合の戸先ゴムの動作例を示している。介在物８がプラットホーム側から引っ張られると、介在物８が、戸先ゴム２ａ内の空気室３の近傍（板厚の薄い部分）を圧迫するため、空気室３の空気圧を敏感に上昇させ、空気室３に連通する図１に示す空気圧センサ５に戸挟みを検知させる。 FIG. 2 is a diagram illustrating Example 1 of the present invention. FIG. 2 shows a cross-section when the door rubber is cut by a plane perpendicular to the longitudinal direction, and reference numeral 2a in FIG. 2 denotes a door rubber having directivity in sensitivity. The cross-sectional shape of the air chamber 3 provided in the door rubber 2a is semicircular (may be elliptical), and the air chamber 3 is disposed inside the door rubber 2a, and the door rubber. The outer side of 2a is solid.
FIG. 2A shows an example of the operation of the door-end rubber when the inclusion 8 sandwiched between the passenger doors 1 is pulled from the platform side (the vehicle outer side). When the inclusion 8 is pulled from the platform side, the inclusion 8 presses the vicinity of the air chamber 3 in the door rubber 2a (the thin portion of the plate thickness), so that the air pressure of the air chamber 3 is increased sensitively, The air pressure sensor 5 shown in FIG.

図２（Ｂ）は、乗降扉１に挟まれた介在物８が車内側から引っ張られた場合の戸先ゴムの動作例を示す。介在物８が車内側から引っ張られると、介在物８は、戸先ゴム２ａの中実部を圧迫するため、空気室３内の空気圧に変化を与えない。従って、図１に示す空気圧センサ５は戸挟みを検知しない。
図２に示す構成を採る戸先ゴムによれば、コストアップや設置スペースの増加なしに、乗降扉に挟まれた介在物８をプラットホーム側から引っ張った場合と車内側から引っ張った場合の戸挟みの検知感度を異ならせて、検知感度に指向性を持たせることが可能になる。その結果、危険性が高い車外側からの引っ張りに対しては、戸挟みを敏感に検知して事故を確実に防止でき、危険性の低い車内側からの引っ張りに対しては、戸挟みを検知しないで、定時運行を維持することができる。
なお、図２では、戸先ゴムを乗降扉の開閉方向に対して車内側と車内側に二分したとき、空気室３が戸先ゴム２ａの車内側部分に配置されている場合について示しているが、戸先ゴム２ａの空気室３は、要は介在物８が車外側から引っ張られた場合に空気室３が変形し、介在物８が車内側から引っ張られた場合に空気室３が変形しないように配置されていればよく、空気室が車内側寄りに配置されるなど、その他の任意の構成を採ることができる。 FIG. 2B shows an example of the operation of the door-end rubber when the inclusion 8 sandwiched between the passenger doors 1 is pulled from the inside of the vehicle. When the inclusion 8 is pulled from the inside of the vehicle, the inclusion 8 presses the solid portion of the door rubber 2a, so that the air pressure in the air chamber 3 is not changed. Therefore, the air pressure sensor 5 shown in FIG. 1 does not detect the door pinching.
According to the door rubber having the configuration shown in FIG. 2, the door is sandwiched when the inclusion 8 sandwiched between the passenger doors is pulled from the platform side and from the inside of the vehicle without increasing the cost and increasing the installation space. The detection sensitivity can be made different so that the detection sensitivity can have directivity. As a result, it is possible to detect the door pinch sensitively when pulling from the outside of the vehicle, which has a high risk, and to prevent accidents, and to detect the pinch pin, when pulling from the inside of the low risk vehicle. Without being able to maintain regular service.
FIG. 2 shows a case where the air chamber 3 is disposed in the vehicle interior side of the door rubber 2a when the door rubber is divided into the vehicle inner side and the vehicle inner side with respect to the opening / closing direction of the passenger door. However, the air chamber 3 of the door rubber 2a is basically deformed when the inclusion 8 is pulled from the outside of the vehicle, and deformed when the inclusion 8 is pulled from the inside of the vehicle. It is only necessary that the air chambers are arranged so as not to be disposed, and any other configuration such as the air chamber being arranged closer to the vehicle interior side can be adopted.

図３は、本発明の実施例２を説明する図である。図３中の２ｃは、感度に指向性を持たせると共に、戸挟み時の検知感度を敏感にする戸先ゴムである。戸先ゴム２ｃは、乗降扉１が閉じるときに接触する一対のゴムからなり、当該一対の戸先ゴム２ｃに設けられた断面形状が半円状の空気室３の直線部分は、半円状の空気室３の円弧部分が対向するように該乗降扉の開閉方向に対してそれぞれ異なった方向に傾いており、かつ、それぞれの空気室の円弧部分が該戸先ゴムの先端部の近傍に位置し、さらに、該円弧部分が車内側を向くように配置される。図３中では、空気室３が、その直線部分が乗降扉１の開閉方向に対して４５度傾いて配置されている例を示している。
図３（Ａ）は、乗降扉１に挟まれた介在物８がプラットホーム側から引っ張られた場合の戸先ゴムの動作例を示している。介在物８がプラットホーム側から引っ張られると、介在物８が、戸先ゴム２ｃの空気室３の近傍（板厚の薄い部分）を圧迫するため、空気室３の空気圧を敏感に上昇させ、空気室３に連通する図１に示す空気圧センサ５に戸挟みを検知させる。 FIG. 3 is a diagram for explaining a second embodiment of the present invention. 3c in FIG. 3 is a door-end rubber that gives directivity to the sensitivity and also makes the detection sensitivity when the door is pinched. The door rubber 2c is made of a pair of rubbers that come into contact when the passenger door 1 is closed, and the straight portion of the air chamber 3 having a semicircular cross section provided in the pair of door rubbers 2c is semicircular. The air chamber 3 is inclined in different directions with respect to the opening / closing direction of the passenger door so that the arc portions of the air chamber 3 face each other, and the arc portions of the air chambers are in the vicinity of the tip of the door rubber And the arc portion is arranged so as to face the vehicle interior side. In FIG. 3, an example is shown in which the air chamber 3 is arranged with its straight line portion inclined by 45 degrees with respect to the opening / closing direction of the passenger door 1.
FIG. 3A shows an operation example of the door-end rubber when the inclusion 8 sandwiched between the passenger doors 1 is pulled from the platform side. When the inclusion 8 is pulled from the platform side, the inclusion 8 presses the vicinity of the air chamber 3 of the door rubber 2c (thin portion where the plate thickness is thin). The air pressure sensor 5 shown in FIG.

図３（Ｂ）は、乗降扉１に挟まれた介在物８が車内側から引っ張られた場合の戸先ゴムの動作例を示す。介在物８が車内側から引っ張られると、介在物８は、戸先ゴム２ｃの中実部を圧迫するため、空気室３内の空気圧に変化を与えない。従って、図１に示す空気圧センサ５は戸挟みを検知しない。
図３（Ａ）及び図３（Ｂ）を参照して動作を説明した戸先ゴム２ｃによれば、コストアップや設置スペースの増加なしに、乗降扉１に挟まれた介在物８をプラットホーム側から引っ張った場合と車内側から引っ張った場合の、戸挟みの検知感度を異ならせて、検知感度に指向性を持たせることが可能になる。その結果、危険性が高い車外側からの引っ張りに対しては、戸挟みを敏感に検知して事故を確実に防止でき、危険性の低い車内側からの引っ張りに対しては、戸挟みを検知しないで、定時運行を維持することができる。 FIG. 3B shows an example of the operation of the door-end rubber when the inclusion 8 sandwiched between the passenger doors 1 is pulled from the inside of the vehicle. When the inclusion 8 is pulled from the inside of the vehicle, the inclusion 8 presses the solid portion of the door rubber 2c, so that the air pressure in the air chamber 3 is not changed. Therefore, the air pressure sensor 5 shown in FIG. 1 does not detect the door pinching.
According to the door rubber 2c whose operation has been described with reference to FIGS. 3 (A) and 3 (B), the inclusion 8 sandwiched between the passenger doors 1 can be placed on the platform side without increasing the cost and increasing the installation space. It is possible to make the detection sensitivity have directivity by differentiating the detection sensitivity of the door clamp when pulled from the vehicle and when pulled from the inside of the vehicle. As a result, it is possible to detect the door pinch sensitively when pulling from the outside of the vehicle, which has a high risk, and to prevent accidents, and to detect the pinch pin, when pulling from the inside of the low risk vehicle. Without being able to maintain regular service.

図３（Ｃ）は乗降扉１に介在物８が挟まれた場合の戸先ゴムの動作例を示している。乗降扉１に介在物８が挟まれると、介在物８が、戸先ゴム２ｃの先端部を圧迫するため、該先端部の近傍に円弧部分が位置するように配置された空気室３の空気圧を敏感に上昇させ、空気室３に連通する図１に示す空気圧センサ５に戸挟みを検知させる。
図３（Ｃ）を参照して動作を説明した戸先ゴム２ｃによれば、コストアップや設置スペースの増加なしに、乗降扉１に介在物８が挟まれた場合の戸挟みの検知感度を敏感にすることができ、戸挟みによる事故を確実に防止できる。 FIG. 3C shows an example of the operation of the door-end rubber when the inclusion 8 is sandwiched between the passenger door 1. When the inclusion 8 is sandwiched between the entrance door 1 and the inclusion 8 presses the tip of the door rubber 2c, the air pressure of the air chamber 3 arranged so that the arc portion is located in the vicinity of the tip is provided. The air pressure sensor 5 shown in FIG. 1 communicating with the air chamber 3 is caused to detect the pinching of the door.
According to the door rubber 2c whose operation has been described with reference to FIG. 3 (C), the detection sensitivity of the door pinching when the inclusion 8 is pinched by the passenger door 1 without increasing the cost or increasing the installation space. It can be made sensitive, and accidents caused by door pinching can be reliably prevented.
