並且，由於零件數增加也會使得成本上升。另外，取代將 關門開關固定於車體，可考慮設置在一方的門上，以另一 方的門使關門開關動作，但是隨著門的開關關門的配線也 會與開閉行程產生同樣程度大的移動，容易造成配線的斷 線，確實檢測雙開式的門是否位在全關閉位置上有其困難 。並且由於更要求配線的持久性，也會使得成本增加。 本發明是有鑑於上述實情，提供以不增加開關的數量 ，可更爲確實地檢測出雙開式的門是否爲全關閉位置的鐵 道車輛用門開關及具備該門開關之鐵道車輛用門開閉裝置 爲目的。 〔解決課題用的手段〕 本發明所涉及鐵道車輛用門開關的第1特徵爲設置在 具備雙開式的門之鐵道車輛的鐵道車輛用門開關，具備： 設置成可對車輛主體相對移動，一方的門朝向全關閉位置 移動時彈推的第1受動部；設置成可對上述車輛主體及上 述第1受動部相對移動，另一方的門朝向全關閉位置移動 -6-

門皆到達全關閉位置時，構成上述第1受動部可對上述第2 受動部移動上述預定量。 根據此一構成時，利用第1受動部抵抗彈性構件的彈 力相對於第2受動部移動預定量時輸出檢測訊號的限位開 關，可實現更爲確實地檢測雙開式的門是否位於全關閉位 置的構成。因此，例如也可以利用以往即廣泛使用的可靠 性高的限位開關，可確保鐵道車輛用門開關的可靠性。 並且，本發明所涉及鐵道車輛用門開關的第4特徵爲 上述第1受動部及上述第2受動部是可自由迴轉地被設置在 固定於上述車輛主體的迴轉軸周圍，上述迴轉軸是朝平板 狀的門的垂直方向延伸。 根據此一構成時，將第1受動部及第2受動部形成與迴 轉軸平行的方向爲較薄厚度，可容易實現省空間化。 又’本發明所涉及鐵道車輛用門開關的第5特徵爲上 述檢測手段在設於上述第1受動部的第1檢測部及設於上述 第2受動部的第2檢測部形成預定的位置關係時，輸出檢測

而使得門不能完全關閉時，因錯誤檢測出門爲關閉之檢測 訊號的輸出。 此外，本發明所涉及的鐵道車輛用門開閉裝置爲雙開 式的門開閉用的鐵道車輛用之門開閉裝置，具備：具有上 述第1〜5的特徵的至少其中之一特徵的鐵道車輛用門開關 ，及接收來自上述檢測手段所輸出檢測訊號的控制部，上 述控制部是根據上述檢測訊號，驅動上述門鎖定用的鎖定 裝置，及控制門開閉用的驅動輸出。 根據此一構成時，可確實檢測雙開式的門是否位於全 關閉位置，可將檢測手段所輸出的檢測訊號，利用於門的 鎖定，或門的驅動控制。 藉此，可防止門未到達全關閉位置時，即因錯誤而鎖 緊門。並可防止門未到達全關閉位置時，即因錯誤而控制 門開閉用的驅動輸出。 〔發明效果〕 根據本發明的鐵道車輛用門開關及具備該門開關的鐵 道車輛用門開閉裝置，不須增加開關的數量，及可更爲確 -9- 201111609

整體的平板狀的門。並且，齒條齒輪機構，具備：朝著車 輛前後方向延伸的一對齒條3a、3b，及分別咬合該等一對 齒條3a、3b的小齒輪（未圖不）所構成。 該門開閉裝置1，具有：固定在車輛主體的可正反向 轉動的直接驅動方式的電動馬達（未圖示），及將該電動 馬達的轉動傳達至齒條齒輪機構用的行星齒輪機構4。並 且，可藉著該電動馬達的驅動，經由行星齒輪機構4轉動 小齒輪，使咬合該小齒輪的一對齒條3a、3b朝著彼此相反 方向移動。 —對齒條3a、3b是分別經連結機構，連結在門100a及 門l〇〇b。該連結機構，具有：固定在齒條3a、3b前端的齒 條側架5a、5b ;固定在該齒條側架5a、5b的軌道構件6a、 -10- 201111609 6b ;及分別固定在該軌道構件6a、6b的門吊掛用架7a、7b ο 軌道構件6a、6b是藉著固定在車輛主體的導軌8a、8b 被引導朝著與齒條側架5 a、“的移動方向平行。又，門吊 掛用架7a、7b分別被固定門i〇〇a及門i〇〇b上端部的2處。 根據此一構成時，以門開閉裝置1的電動馬達朝一方 向轉動小齒輪，使齒條3b在車輛的前方（第1圖及第2圖的 右方）移動，藉以使得門l〇〇b在車輛的前方移動。此時， 齒條3a在車輛的後方（第1圖及第2圖的左方）移動而使門 1 00a在後方移動。即，以門開閉裝置1的電動馬達使小齒 輪朝著此一方向轉動，可使門100a及門100b同時朝著開方 向（第1圖及第2圖的箭頭XI方向）移動。並且，以門開閉 裝置1的電動馬達使小齒輪朝著此一方向的相反方向轉動 ，可使門l〇〇a及門10 0b同時朝著關閉方向（第1圖及第2圖 的箭頭X2方向）移動。 如上述，可藉著門開閉裝置1，進行門l〇〇a及門100b 的開閉動作。 再者，不僅限於使用齒條齒輪機構開閉門的構成，也 可藉皮帶連結電動馬達與門進行門的開閉驅動的方式，或 是使用滾珠螺桿進行門的開閉驅動的方式、使用線性馬達 進行門的開閉驅動的方式、使用空氣或油等的流體進行門 的開閉驅動的方式。 並且，門開閉裝置1具備可檢測門l〇〇a及門100b爲完 全關閉狀態的門開關1 〇。 -11 - 201111609 該門開關ι〇是在車輛前後方向的乘降口的中央部上方 (行星齒輪機構4的下方），藉基板9所配置。亦即，門開 關10被配置在位於全關閉位置的門l〇〇a、100b的門緣上方 <門開關的構成> 第2圖爲第1圖表示設於門開閉裝置1之門開關1 〇附近 部的放大圖。並且，第3圖是從平行於門l〇〇a、l〇〇b的開 閉方向的車輛前方側（襯墊3 5側）所顯示第2圖表示之門 開關10的圖。又，第4(a)圖是由和基板9的相反側顯示 門開關1 〇的圖。且於第4 ( a )圖中，如限位開關20的內部 構造可理解，省略限位開關20之主體盒2 1的一部份表示。 並且第4 ( b )圖是從箭頭A方向顯示第4 ( a )圖表示之門 開關1 〇的圖。 如第2圖表示，門開關1 〇，具備：限位開關20，及收 容該限位開關20的箱型的開關盒3 0。 如第3圖表示，開關盒30是經由軌道40固定在基板9。 如第3圖及第4圖表示，軌道40是被固定在基板9朝著 門100a、100b的開閉方向平行延伸。並且，開關盒30的底 板31固定有和軌道40卡合的引導構件32。該引導構件32在 卡合於該滑軌40的狀態下，可沿著該滑軌40移動。藉此， 開關盒30可沿著軌道4〇，在與門l〇〇a、l〇〇b的開閉方向平 行地移動。並且，本實施例中，開放開關盒30的底板3 1的 相反側，可容易進行限位開關20的維護。 -12- 201111609 如第4圖表示，限位開關20具備內部可收容檢測機構 的主體盒21，及從主體盒21突出的桿22。該桿22將其前端 側及基端側插入形成在主體盒2 1的貫穿孔2 1 a、2 1 b ’保持 在該主體盒21可於該主體盒21的軸方向移動。並且’該桿 22的前端被以預定量壓入主體盒21內，藉此構成輸出檢測 訊號（第4圖是表示將桿22壓入的狀態。針對桿22未壓入 的狀態可參閱第5圖）。 具體而言，桿22在軸向中間部具有和前端側及基端側 比較形成擴徑的擴徑部22a。並且，在擴徑部22a與主體盒 21之間配置有彈簧23。該彈簧23被配置在桿22基端側的軸 周圍，將擴徑部2 2a朝著軸向前端側彈推。又，從擴徑部 22a與軸向正交的方向延伸出一對的板部24。主體盒21內 設有該板部24可以預定量朝著與桿22的軸向平行移動的空 間。並且，對此一對板部24，在朝著桿22的軸向基端側對 向的位置，設有一對電極25。一對板部Μ抵接於該一對電 極25時，電連接該等的一對電極25，構成預定的電路輸出 檢測訊號。 藉此，將桿22的前端朝著軸向彈推，使該桿22抵抗彈 簧23的彈推力朝著軸向基端側移動預定量時，使該等一對 板部24抵接於一對的電極25，將檢測訊號輸出至門開閉裝 置1的控制部。 再者，門開閉裝置1具備有以CPU及記億體的微電腦 等所構成的控制部。並且，從限位開關20輸出的檢測訊號 是經由配線連接器3 7及未圖示的配線，輸入至該控制部。 •13- 201111609 控制部是根據該檢測訊號，控制門的開閉機構及門的鎖定 裝置等。 該限位開關20將桿22的前端貫穿形成在開關盒30的側 壁3 3的貫穿孔3 3 a，配置在該開關盒3 0內突出於開關盒3 0 的外側。該限位開關20是以螺栓等固定在開關盒30的底板 31。在此，限位開關20是配置使桿22的軸與軌道40平行延 伸。 並且，開關盒30的位在與形成有桿22貫穿之貫穿孔 3 3 a的側壁3 3相反側的側壁3 4的外面，固定著以橡膠等， 剛性較側壁34低的構件所形成圓盤形的襯墊35»此外，本 1Ϊ施例中，雖是構成以橡膠構成的襯墊35來防止隨著門的 抵接產生對門開關1 0的過度衝擊，但是本實施例也具備有 後述的緩衝機構，因此襯墊3 5也可以是金屬，並且如對側 壁3 4不會產生變形等不良的影響也可以不具有襯墊。 如第2圖表示，在一對的門100a、10 Ob上端部的門緣 附近部，分別固定有向上方延伸的支撐構件5 1 a、5 1 b。該 等支撐構件51a、51b安裝有與門100a、100b的開閉方向平 行延伸的彈推軸52a、52b。 從門開關10顯示，設置在位於桿22前端側的門l〇〇a的 彈推軸52a是被配置成與該桿22大致同軸。並且，該彈推 軸52a的前端（與桿22的前端對向的端部），固定著與該 彈推軸52a正交的彈推板53a。並在門100a朝著關閉方向移 動時，構成可以該彈推板53 a彈推桿22的前端。 從門開關10顯示，設置在位於襯墊35側的門l〇〇b的彈 -14- 201111609 推軸52b是被配置成與圓盤形襯墊35的中心軸大致同軸。 並且，該彈推軸52b的前端（與襯墊35對向的端部），固 定著與該彈推軸52b正交的彈推板53b。並在門10 Ob朝著關 閉方向移動時，構成可以該彈推板53b彈推襯墊35。 此外，該等彈推軸52a ' 52b分別設有減震機構。該等 減震機構具有可實現緩和當門朝著關閉方向移動彈推板 53a、53b抵接於桿22的前端或襯墊35時的衝擊的功能。本 實施例中，該減震機構雖是以彈簧所構成，但是只要可以 緩和隨著門的抵接產生對門開關1 〇的過度衝擊即可，不論 是以彈簧與緩衝器的組合，或是橡膠等的構成皆可。 <門開關的動作> 第6圖爲說明門開關10的動作用的模式圖。 並且，上述實施形態的構成與第6圖模式表示的構成 的對應關係是如下述。 第2圖表示的彈推軸52a、52b及彈推板53a ' 53b是相 當於第6圖的彈推部55a、55b。又，第4圖表示的桿22及一 對板部24是相當於具有第6圖的桿26a及被檢測部26b的桿 單元26。另外，第4圖表示的彈簧23是相當於第6圖的彈簧 27。並且，第4圖表示的開關盒30是相當於第6圖表示的開 關盒36。且第4圖的一對電極25則是相當於第6圖的檢測部 28 ° 第6 ( a )圖是表示雙開式的2個門正常進行關閉動作 的途中的狀態（門1 〇〇a未到達全關閉位置爲止，並且門 -15- 201111609 100b也未到達全關閉位置爲止的狀態）。 第6 ( b )圖是表示2個門正常進行關閉動作，皆到達 全關閉位置爲止時的狀態。 第6 ( c )圖是表示由於門開閉裝置1的故障，僅雙開 式的2個門的一方的門1 0〇a到達全關閉位置爲止的狀態》 第6 ( d )圖是表示由於門開閉裝置1的故障，僅雙開 式的2個門的另一方的門l〇〇b到達全關閉位置爲止的狀態 〇 如第6 ( a )圖表示，2個門位在從全關閉位置僅離開 預定距離的位置時，對門100a、100b分別成固定的彈推部 55a、5 5b未抵接於門開關1〇。在此狀態下，藉彈簧27的彈 推力使檢測部28與被檢測部26b分開。 從第6 ( a )圖表示的狀態，更使得門l〇〇a、l〇〇b朝著 關閉方向移動時，對該等門100a、10 Ob成固定的2個彈推 部55a、55b朝向彼此接近的方向（第6圖的箭頭X2方向） 移動，該等彈推部55a、55b是大致同時抵接於桿26a的前 端及開關盒3 6 (在第6 ( a )圖以兩點虛線表示）。 另外，藉著門100a、100b朝著關閉方向的移動，桿單 元26藉來自彈推部55a的彈推力，抵抗彈簧27的彈推力， 朝著與該彈推部55a移動方向的相同方向移動（參閱第6( b )圖）。 另一方面，開關盒3 6藉來自彈推部5 5 b的彈推力，抵 抗彈簧2?的彈推力，朝著與該彈推部55b移動方向的相同 方向在滑軌40(第6圖中省略）上移動。 -16- 201111609 即，門100a、100b朝著關閉方向移動，變形使彈簧27 收縮，並變化該桿單元26與開關盒36的相對位置關係，使 得被檢測部26b與檢測部28的間隔變窄。 如第6(b)圖表示，雙方的門l〇〇a、l〇〇b到達全關閉 位置爲止時，桿單元26的被檢測部26b抵接於檢測部28。 並且，被檢測部26b—旦抵接於檢測部28時，對門開閉裝 置1的控制部輸出檢測訊號。該控制部接收該檢測訊號時 ’判斷門爲完全關閉，使得拘束門朝著開啓方向移動用的 鎖定裝置動作。具體而言，例如，藉檢測訊號激勵螺線管 ’將設置在該螺線管的鎖桿卡止於門l〇〇a、l〇〇b上，鎖定 該門1 0 0 a、1 0 0 b朝著開啓方向的移動。另外，此時也可以 藉控制部停止門開閉裝置1的小齒輪轉動用的電動馬達的 輸出。 如第6 ( c )圖表示，朝著門i〇〇a、i〇〇b的關閉方向移 動時’門100b的關閉動作停止的場合，只有門100a朝著關 閉方向移動，並只以固定在該門l〇〇a的彈推部55a彈推著 門開關1 〇。亦即，僅直接彈推桿單元2 6。 如上述，僅直接彈推桿單元26，藉以使開關盒36沿著 滑軌40’朝著與彈推部55a的移動方向相同的方向移動。 此時’彈簧27幾乎沒有收縮，被檢測部26b與檢測部28的 間隔和第6 ( a )圖表示狀態的間隔比較，幾乎沒有變化。 因此’門1 00b在未完全關閉的場合，不會從門開關i 〇 輸出檢測訊號。 同樣地，如第6 ( d )圖表示，門1 〇〇a、1 〇〇b朝著關閉 201111609 方向移動時，門100a的關閉動作停止的場合，只有門1001) 朝著關閉方向移動，並只以固定在該門100b的彈推部55b 彈推著門開關1 〇。亦即，此時僅直接彈推開關盒3 6。 如上述’僅直接彈推開關盒3 6，藉以使開關盒3 6和桿 單元26沿著滑軌4〇，朝著與彈推部55b的移動方向相同的 方向移動。此時’彈簧27幾乎沒有收縮，被檢測部26b與 檢測部28的間隔和第6 ( a )圖表示狀態的間隔比較，幾乎 沒有變化。 因此’門l〇〇a在未完全關閉的場合，不會從門開關10 輸出檢測訊號。 <實施形態的效果> (1 )如以上說明，本實施形態涉及的門開閉裝置1具 備門開關1 〇。 該門開關10爲設置在具備雙開式的門100a、l〇〇b之鐵 道車輛的鐵道車輛用的門開關，具備：設置成可相對於基 板9 (車輛主體）相對移動，一方的門l〇〇a朝向全關閉位 置移動時彈推的桿22 (第1受動部）：設置成可對基板9及 桿22相對移動，另一方的門l〇〇b朝向全關閉位置移動時彈 推的開關盒30(第2受動部）；上述桿22和開關盒30的相

簧23的彈推力並以設置在雙開式的2個門100a、100b的彈 推板53a、53b—邊彈推，使該等2個門l〇〇a、1 00b皆移動 至全關閉位置爲止時的桿22與開關盒30的相對位置。 根據此一構成，2個門100a、100b之中，僅一方的門 移動到全關閉位置，而另一方的門未到達全關閉位置爲止 的場合，由於彈簧23的彈推力，使得桿22與開關盒30的相 對位置不形成爲上述預定的相對位置，使板部24與電極25 不會抵接，因此從門開關1 〇對控制部不會輸出檢測訊號。 藉此，不致增加開關的數量，可更爲確實進行雙開式 的門1 00a、1 0Ob是否皆位於全關閉位置的檢測。 (2 )門開關1 0中，桿2 2及開關盒3 0設置可相對於基 板9朝著與門1 00a、1 00b的開閉方向平行移動。 根據此一構成，可利用與門l〇〇a、] 〇〇b的開閉方向平

and a door opening and closing device for a railway vehicle provided with the door switch. [Prior Art] Conventionally, a device for opening and closing a double-open type door is known in the Japanese Patent Publication No. 1. The door opening and closing device mounts the related door switch at substantially the center of the substrate fixed to the vehicle body. Further, when the doors on both sides are completely closed, the switching action metal member of the hanging metal member provided at one of the doors abuts the door closing switch, and the closing of the double-opening door can be detected. Further, the solenoid is energized by the signal from the door closing switch, and the lock lever is locked to the lock device to lock the door. [Prior Art Document] [Patent Document 1] [Japanese Patent Laid-Open Publication No. 2002-309849] DISCLOSURE OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION The above-described door opening and closing device has a structure in which two doors of a double-open type are mechanically interlocked to open and close. Therefore, when the door position of the double-open type is at the fully closed position, usually, The other door is also in the fully closed position. Therefore, by the above-mentioned closing switch, it can be judged whether one of the two doors of the double-opening type 201111609 is in the fully closed position. However, the possibility of malfunctioning the double-opening door linkage mechanism is not zero, so even if the door is interlocked In the event of a mechanical failure, it is still possible to reliably detect whether the double-open door is in the fully closed position of the railway vehicle door switch. For this reason, it is conceivable to provide two of the above-described door closing switches corresponding to the double-opening doors, but once according to this method, the number of switches is increased, and the number of electronic components is increased, which may cause an increase in the overall failure rate of the system. Also, the increase in the number of parts will increase the cost. In addition, instead of fixing the door closing switch to the vehicle body, it is conceivable to install it on one door and the other door to operate the door closing switch. However, the wiring of the door closing and closing will have the same degree of movement as the opening and closing stroke. It is easy to cause the disconnection of the wiring, and it is difficult to detect whether the double-opening door is in the fully closed position. And because the durability of the wiring is more required, the cost is also increased. In view of the above-described circumstances, the present invention provides a door switch for a railway vehicle that can more reliably detect whether a double-open door is a fully closed position and a door opening and closing device for a railway vehicle having the same without increasing the number of switches. for purpose. [Means for Solving the Problem] The first feature of the railway vehicle door switch according to the present invention is a railway vehicle door switch provided in a railway vehicle having a double-open type door, and is provided to be relatively movable to the vehicle body. The first driven portion that is pushed when the door moves toward the fully closed position; the first movable portion that moves relative to the vehicle body and the first driven portion, and the other that moves toward the fully closed position -6-201111609 a receiving portion that outputs a detection signal when the relative position between the first receiving portion and the second receiving portion forms a predetermined relative position; and the first receiving portion and the second receiving portion are pushed to the first portion The relative position between the driven portion and the second driven portion is not formed as a predetermined pushing position, and the predetermined relative position is a spring thrust of the first receiving portion and the second receiving portion against the elastic pushing means And the two positions of the double-opening type are pushed, and the relative positions of the first driven portion and the second driven portion when the two doors are moved to the fully closed position. According to this configuration, when only one of the doors is moved to the fully closed position and the other door does not reach the fully closed position, the first driven portion and the second driven portion are not moved by the spring force of the spring pushing means. The relative positions of the portions form a predetermined relative position, so that no detection signal is output from the detecting means. In this way, the number of switches is not increased, and it is more sure to detect whether the double-opening door is in the fully closed position. Further, in the second aspect of the railway vehicle door switch according to the present invention, the first driven portion and the second driven portion are provided to be movable in parallel with the opening and closing direction of the door with respect to the vehicle body. According to this configuration, the door switch for the railway vehicle can be disposed by a space extending in parallel with the opening and closing direction of the door. Further, a third feature of the door switch for a railway vehicle according to the present invention includes a limit switch including: the first driven portion; and the second driven portion that advances and retracts the first driven portion; a spring 201111609 member that is disposed between the first receiving portion and the second driven portion as the spring pushing member; and the first receiving portion outputs a predetermined amount when the first receiving portion moves by a predetermined amount against the second receiving portion. The above-described detection means of the detection signal is provided so as to be movable in parallel with the forward direction of the first receiving portion with respect to the second receiving portion, and the one door is the first receiving portion. The other door is pushed by the second driven portion, so that the first driven portion moves against the elastic force of the elastic member with respect to the second driven portion, and both of the doors are reached. In the fully closed position, the first actuator may be configured to move the predetermined amount by the second actuator. According to this configuration, it is possible to more reliably detect whether the double-open type door is in the fully closed position by the limit switch that outputs the detection signal when the first driven portion is moved by the predetermined amount by the elastic force of the elastic member with respect to the second driven portion. Composition. Therefore, for example, it is also possible to secure the reliability of the door switch for a railway vehicle by using a highly reliable limit switch which has been widely used in the past. Further, a fourth feature of the railway vehicle door switch according to the present invention is that the first driven portion and the second driven portion are rotatably provided around a rotary shaft fixed to the vehicle body, and the rotary shaft is directed toward The flat door extends in the vertical direction. According to this configuration, the first receiving portion and the second receiving portion are formed to have a thin thickness in a direction parallel to the rotation axis, and space saving can be easily realized. According to a fifth aspect of the present invention, in the first aspect of the present invention, the first detecting unit provided in the first receiving unit and the second detecting unit provided in the second receiving unit form a predetermined positional relationship. When the detection signal is output, the first detecting unit is disposed at a position farther from the rotation axis of the first driven portion than the position of the door at the first actuator in the first receiving portion. The detecting portion is disposed at a position farther from the rotation axis of the second driven portion than the position at which the door is pushed by the second receiving portion. According to this configuration, the amount of change in the relative position between the first detecting unit and the second detecting unit is increased in comparison with the amount of movement in the closing direction of the door. Thereby, it is possible to easily prevent the output of the detection signal in which the door is closed due to an erroneous detection when the door is not completely closed due to the foreign matter being caught between the doors during the closing operation. Further, the door opening and closing device for a railway vehicle according to the present invention is a door opening and closing device for a railway vehicle for opening and closing a double-open type, and includes a door for a railway vehicle having at least one of the features of the first to fifth features. And a switch for receiving a detection signal outputted from the detection means, wherein the control unit drives the lock device for locking the door and the drive output for opening and closing the door based on the detection signal. According to this configuration, it is possible to surely detect whether or not the double-open type door is in the fully closed position, and the detection signal outputted by the detecting means can be used for the locking of the door or the driving control of the door. Thereby, it is possible to prevent the door from being locked due to an error when the door does not reach the fully closed position. It can prevent the drive output of the door opening and closing due to an error when the door does not reach the fully closed position. [Effect of the Invention] The door switch for a railway vehicle according to the present invention and the door opening and closing device for a railway vehicle provided with the door switch do not need to increase the number of switches, and can more accurately detect whether the double-open type door is -9-201111609 w Located in the fully closed position. [Embodiment] Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings. <Configuration of Door Opening and Closing Apparatus> Fig. 1 is a general view showing a door opening and closing device 1 according to an embodiment of the present invention. The door opening and closing device 1 is fixed to the side wall of the railway vehicle main body via the substrate 2. The door opening and closing device 1 is a device that opens and closes a double-open type door (door 100a, door 1 〇 Ob) using a rack and pinion mechanism.

The door hangers 7a and 7b are respectively fixed to the upper end of the door i〇〇a and the door i〇〇b. According to this configuration, the electric motor of the door opening and closing device 1 rotates the pinion gear in one direction, so that The rack 3b moves in front of the vehicle (to the right of FIGS. 1 and 2), so that the door l〇〇b moves in front of the vehicle. At this time, the rack 3a is behind the vehicle (Fig. 1 and The left side of the figure 2 moves to move the door 100a back. That is, the electric motor of the door opening and closing device 1 rotates the pinion gear in this direction, so that the door 100a and the door 100b can be simultaneously turned toward the opening direction (the 1 and the arrow XI direction of the second figure) move, and the electric motor of the door opening and closing device 1 causes the pinion gear to face this side. Rotating in the opposite direction causes the door 10a and the door 10b to simultaneously move in the closing direction (the direction of the arrow X2 in the first and second figures). As described above, the door can be opened by the door opening and closing device 1. L〇〇a and the opening and closing operation of the door 100b. Further, the present invention is not limited to the configuration in which the rack and pinion mechanism is used to open and close the door, and the electric motor and the door may be connected by a belt to open and close the door, or the ball may be used to open the door.

The door opening and closing device 1 is provided with a detectable door 10a and a door 100b. The door switch 1 is fully closed. -11 - 201111609 The door switch ι is located above the center of the boarding and lowering of the vehicle in the front-rear direction of the vehicle (below the planetary gear mechanism 4), and is disposed by the substrate 9. That is, the door The switch 10 is disposed above the door edge of the doors l〇〇a, 100b at the fully closed position <Configuration of the door switch> Fig. 2 is a view showing the vicinity of the door switch 1 设 of the door opening and closing device 1 Magnified view. In addition, Fig. 3 is a view showing the door switch 10 shown in Fig. 2 from the front side of the vehicle (the side of the spacer 3) parallel to the opening and closing direction of the doors 10a, lb. (a) is a diagram showing the door switch 1 由 from the opposite side of the substrate 9. And in the fourth (a) diagram, as the internal structure of the limit switch 20 is understood, the main body box 2 of the limit switch 20 is omitted. Part of 1 is shown in Fig. 4 and Fig. 4(b) is a view showing the door switch 1 表示 shown in Fig. 4 (a) from the direction of arrow A. As shown in Fig. 2, the door switch 1 〇 has: limit The switch 20 and a box type switch box 30 that houses the limit switch 20. As shown in FIG. 3, the switch box 30 is fixed to the substrate 9 via the rail 40. As shown in Figs. 3 and 4, the rail 40 is fixed to the substrate 9 so as to extend in parallel in the opening and closing direction of the doors 100a and 100b. Further, the bottom plate 31 of the switch case 30 is fixed with a guide member 32 that engages with the rail 40. The guide member 32 is movable along the slide rail 40 in a state of being engaged with the slide rail 40. Thereby, the switch case 30 can be moved in parallel with the opening and closing directions of the doors l〇〇a, lb along the rail 4〇. Further, in the present embodiment, the opposite side of the bottom plate 31 of the switch case 30 is opened, and the maintenance of the limit switch 20 can be easily performed. -12- 201111609 As shown in Fig. 4, the limit switch 20 is provided with a main body case 21 in which a detecting mechanism can be housed, and a rod 22 projecting from the main body case 21. The rod 22 is inserted into the through hole 2 1 a, 2 1 b ' formed in the main body casing 21 by the front end side and the base end side thereof, and the main body case 21 is movable in the axial direction of the main body case 21. Further, the tip end of the rod 22 is pressed into the main body casing 21 by a predetermined amount, thereby constituting an output detection signal (Fig. 4 is a view showing a state in which the rod 22 is pressed in. For the state in which the rod 22 is not pressed, see the fifth. Figure). Specifically, the rod 22 has an enlarged diameter portion 22a that expands in diameter in the axially intermediate portion as compared with the distal end side and the proximal end side. Further, a spring 23 is disposed between the enlarged diameter portion 22a and the main body casing 21. The spring 23 is disposed around the shaft on the proximal end side of the rod 22, and the enlarged diameter portion 22a is pushed toward the distal end side in the axial direction. Further, a pair of plate portions 24 are extended from the direction in which the enlarged diameter portion 22a is orthogonal to the axial direction. The main body casing 21 is provided with a space in which the plate portion 24 can be moved in a predetermined amount toward the axial direction of the rod 22. Further, the pair of plate portions 24 are provided with a pair of electrodes 25 at positions facing the proximal end side of the rod 22 in the axial direction. When the pair of plate portions Μ abut against the pair of electrodes 25, the pair of electrodes 25 are electrically connected to form a predetermined circuit output detection signal. Thereby, the front end of the rod 22 is urged in the axial direction, and when the rod 22 is moved toward the axial proximal end side against the elastic thrust of the spring 23 by a predetermined amount, the pair of plate portions 24 are abutted against the pair. The electrode 25 outputs a detection signal to the control unit of the door opening and closing device 1. Further, the door opening and closing device 1 is provided with a control unit including a CPU and a microcomputer. Further, the detection signal outputted from the limit switch 20 is input to the control unit via the wiring connector 37 and a wiring (not shown). • 13- 201111609 The control unit controls the opening and closing mechanism of the door and the locking device of the door based on the detection signal. The limit switch 20 has a front end of the rod 22 penetrating through the through hole 3 3 a formed in the side wall 33 of the switch case 30, and is disposed in the switch case 30 so as to protrude outside the switch case 30. The limit switch 20 is fixed to the bottom plate 31 of the switch case 30 by bolts or the like. Here, the limit switch 20 is configured such that the shaft of the rod 22 extends in parallel with the rail 40. Further, the switch case 30 is fixed to the outer side of the side wall 34 of the side opposite to the side wall 33 of the through hole 3 3 a through which the rod 22 is formed, and is formed of a member made of rubber or the like and having a lower rigidity than the side wall 34. In addition, in the first embodiment, the spacer 35 made of rubber is formed to prevent excessive impact on the door switch 10 due to the contact of the door. However, the present embodiment is also provided with a later-described embodiment. The cushioning mechanism is such that the gasket 35 may be metal, and may have no gasket as long as it does not cause deformation or the like on the side wall 34. As shown in Fig. 2, support members 5 1 a and 5 1 b extending upward are fixed to the vicinity of the door edge of the upper end portions of the pair of doors 100a and 10 Ob, respectively. The support members 51a and 51b are attached with pinion shafts 52a and 52b extending in parallel with the opening and closing directions of the doors 100a and 100b. From the door switch 10, the pinch shaft 52a provided on the front end side of the rod 22 is disposed substantially coaxially with the rod 22. Further, a tip end portion of the projectile shaft 52a (an end portion opposed to the front end of the rod 22) is fixed to a poppet 53a orthogonal to the pinion shaft 52a. When the door 100a is moved in the closing direction, the front end of the push rod 22 can be formed by the poppet 53a. From the door switch 10, the spring of the door 10b located on the side of the pad 35 is shown. The push shaft 52b is disposed substantially coaxially with the central axis of the disc-shaped pad 35. Further, the tip end of the pinch shaft 52b (the end portion opposed to the pad 35) fixes the poppet 53b orthogonal to the pinion shaft 52b. When the door 10 Ob is moved in the closing direction, the pad 35 can be pushed by the poppet 53b. Further, the pinch shafts 52a' 52b are respectively provided with a damper mechanism. These damper mechanisms have a function of mitigating an impact when the door moves toward the closing direction by the urging plates 53a, 53b abutting against the front end of the rod 22 or the pad 35. In this embodiment, although the damper mechanism is constituted by a spring, it is possible to alleviate excessive impact on the door switch 1 随着 with the abutment of the door, whether it is a combination of a spring and a damper, or a rubber. The composition of etc. can be. <Operation of Door Switch> Fig. 6 is a schematic view for explaining the operation of the door switch 10. Further, the correspondence between the configuration of the above embodiment and the configuration shown in the sixth mode is as follows. The pinch shafts 52a and 52b and the poppet plates 53a' to 53b shown in Fig. 2 are the push portions 55a and 55b corresponding to Fig. 6. Further, the rod 22 and the pair of plate portions 24 shown in Fig. 4 correspond to the rod unit 26 having the rod 26a and the detected portion 26b of Fig. 6 . Further, the spring 23 shown in Fig. 4 is a spring 27 corresponding to Fig. 6. Further, the switch box 30 shown in Fig. 4 corresponds to the switch box 36 shown in Fig. 6. Further, the pair of electrodes 25 in Fig. 4 corresponds to the detecting portion 28 of Fig. 6 and Fig. 6(a) shows the state in which the two doors of the double-open type are normally in the closing operation (door 1 〇〇 a not It reaches the fully closed position, and the door -15-201111609 100b has not reached the state of the fully closed position). Figure 6 (b) shows the state in which the two doors are normally closed, and they all reach the fully closed position. Fig. 6(c) is a view showing a state in which only one of the doors of the two doors of the double-open type reaches the fully closed position due to the failure of the door opening and closing device 1. Chapter 6(d) shows that the door is opened and closed. In the failure of the device 1, only the other door of the two doors of the double-open type reaches the fully closed position, as shown in the sixth (a) diagram, and the two door positions are only separated from the fully closed position. At the position of the distance, the latching portions 55a and 55b, which are fixed to the doors 100a and 100b, respectively, are not in contact with the door switch 1A. In this state, the detecting portion 28 is separated from the detected portion 26b by the spring force of the spring 27. When the doors l〇〇a, l〇〇b are moved in the closing direction from the state shown in Fig. 6(a), the two latching portions 55a, 55b that are fixed to the doors 100a, 10 Ob are oriented. The directions in which they approach each other (the direction of the arrow X2 in Fig. 6) are moved, and the projecting portions 55a and 55b are abutted at the front end of the rod 26a and the switch box 36 at substantially the same time (the dotted line at two points in the sixth (a) diagram Express). Further, by the movement of the doors 100a, 100b in the closing direction, the lever unit 26 moves against the spring force of the spring 27 against the spring force of the spring pushing portion 55a in the same direction as the moving direction of the spring pushing portion 55a ( See Figure 6(b)). On the other hand, the switch box 36 is biased against the spring 2 from the spring force of the spring pushing portion 5 5 b toward the sliding rail 40 in the same direction as the moving direction of the spring pushing portion 55b (Fig. 6) Omit) move up. -16- 201111609 That is, the doors 100a, 100b are moved in the closing direction, the deformation causes the spring 27 to contract, and the relative positional relationship between the lever unit 26 and the switch case 36 is changed, so that the interval between the detected portion 26b and the detecting portion 28 is narrowed. . As shown in Fig. 6(b), when both the doors l〇〇a and l〇〇b reach the fully closed position, the detected portion 26b of the lever unit 26 abuts against the detecting unit 28. When the detected portion 26b comes into contact with the detecting portion 28, the control portion of the door opening and closing device 1 outputs a detection signal. When the control unit receives the detection signal, the door is judged to be completely closed, so that the lock device for restricting the movement of the door toward the opening direction is operated. Specifically, for example, the lock signal is excited by the detection signal to lock the lock lever provided on the solenoid to the doors l〇〇a, l〇〇b, and lock the door 1 0 0 a, 1 0 0 b moves toward the opening direction. Further, at this time, the output of the electric motor for turning the pinion of the door opening and closing device 1 may be stopped by the control unit. As shown in the sixth figure (c), when the closing operation of the door 100b is stopped when moving in the closing direction of the doors i〇〇a and i〇〇b, only the door 100a moves in the closing direction, and is fixed only in the closing direction. The poppet portion 55a of the door l〇〇a pushes the door switch 1 弹. That is, only the pusher unit 26 is directly pushed. As described above, only the pusher unit 26 is directly pushed, whereby the switch box 36 is moved in the same direction as the moving direction of the spring pushing portion 55a along the slide rail 40'. At this time, the spring 27 hardly contracts, and the interval between the detected portion 26b and the detecting portion 28 is compared with the interval between the states shown in Fig. 6(a), and there is almost no change. Therefore, when the door 1 00b is not completely closed, the detection signal is not output from the door switch i 。. Similarly, as shown in Fig. 6(d), when the door 1 〇〇a, 1 〇〇b moves toward the closing 201111609, when the closing operation of the door 100a is stopped, only the door 1001) moves toward the closing direction, and Only the poppet portion 55b fixed to the door 100b pushes the door switch 1 弹. That is, at this time, only the switch box 36 is directly pushed. As described above, only the switch box 3 6 is directly pushed, whereby the switch case 36 and the lever unit 26 are moved along the slide rail 4 in the same direction as the moving direction of the spring pushing portion 55b. At this time, the spring 27 hardly contracts, and the interval between the detected portion 26b and the detecting portion 28 is almost unchanged from the interval at which the state is indicated by the sixth (a) diagram. Therefore, when the door l〇〇a is not completely closed, the detection signal is not output from the door switch 10. <Effects of the Embodiments> (1) As described above, the door opening and closing device 1 according to the present embodiment has the door switch 1 〇. The door switch 10 is a door switch for a railway vehicle provided in a railway vehicle having double-open doors 100a and 100b, and is provided to be relatively movable with respect to the substrate 9 (vehicle body), and one door is closed. The lever 22 (first receiving portion) that is pushed when the 〇a moves toward the fully closed position: a switch that is provided to be able to move relative to the substrate 9 and the rod 22 while the other door 10b is moved toward the fully closed position The cartridge 30 (second receiving portion); the relative positions of the rod 22 and the switch box 30 form a predetermined relative position, and are fixed to the pair of plate portions 24 of the rod 22 to abut against a pair of electrodes 25 fixed to the switch box 30. When the electronic circuit (detection means) for outputting the detection signal, and the push rod 22 and the switch box 30 make the relative position of the rod 22 and the switch box 30 not formed as the predetermined relative position (-18-201111609, the plate portion 24) A spring 23 (a spring pushing means) that is in a relative position when the electrode 25 is in contact with the electrode 25. Here, the predetermined relative position is such that the lever 22 and the switch box 30 resist the spring force of the spring 23 and are pushed by the poppets 53a, 53b of the two doors 100a, 100b of the double opening type, so that the 2 The relative positions of the lever 22 and the switch box 30 when the doors l〇〇a and 100b are moved to the fully closed position. According to this configuration, when only one of the two doors 100a and 100b moves to the fully closed position and the other door does not reach the fully closed position, the lever 22 and the switch are caused by the spring force of the spring 23. The relative position of the cartridge 30 is not formed at the predetermined relative position, and the plate portion 24 and the electrode 25 are not in contact with each other. Therefore, the control signal is not outputted from the door switch 1 to the control portion. Thereby, it is possible to more reliably detect whether the double-opening doors 100a, 100b are in the fully closed position without increasing the number of switches. (2) In the door switch 10, the lever 2 2 and the switch box 30 are disposed to be movable in parallel with respect to the base plate 9 in the opening and closing direction of the door doors 100a and 100b. According to this configuration, the door switch 1 配置 can be arranged by a space extending in parallel with the opening and closing direction of the doors l〇〇a, 〇〇b. Thereby, it is possible to use the door l〇〇a, 100b in the space below the door drive mechanism (electric motor, planetary gear mechanism 4, rack and pinion mechanism, etc.)

100a、100b，隨著門100a、l〇〇b的移動而移動。 開關盒61被直接固定在基板9。即》開關盒61被固定 成不能.對車輛主體相對地移動。 桿62配置使其前端從開關盒6 1突出，基端位於開關盒 61內。設置該桿62可相對於開關盒61朝著軸向自由進退。 此外，桿62的進退方向是與門的開閉方向平行。 桿62與開關盒61之間配置有彈簧64。該彈簧64是從基 端側朝著前端側彈推桿62。 並且桿62在軸向的中間部固定著磁鐵66。該磁鐵66被 固定在桿62與桿63側對向。 另外，隨著門l〇〇a的關閉動作，使彈推部56a朝著關 閉方向移動，藉此構成以該彈推部56a彈推桿62的前端。 桿63配置使其前端從開關盒61朝著與桿62的相反方向 突出，使其基端位於開關盒6 1內。該桿63被設置相對於開 關盒61朝著軸向自由進退。再者’桿63的進退方向是和門 的開閉方向平行。 並且，桿63在正交於基板9的方向（第7圖的紙面深度 方向）中，配置與桿6 2大致相同位置。即’從與鉛直方向 平行顯示，配置桿6 2、6 3使得桿6 2的中心軸與桿6 3的中心 軸位在同一直線形的位置。 桿63和開關盒61之間配置有彈簧65。該彈簧65是將桿 63從基端側朝向前端側彈推。 -22- 201111609 又，桿6 3在軸向的中間部固定著磁感測器6 7。該磁感 測器67被固定在桿63與桿62側對向。 並且，隨著門l〇〇b的關閉動作，使彈推部56b朝著關 閉方向移動，藉此構成以該彈推部5 6b彈推桿63的前端。 如第7 (a)圖表示，在桿62、63對彈推部56a、56b未 加以彈推的狀態下，桿62是藉著彈簧64的彈推力以在彈推 部5 6a側移動的狀態保持著，桿63是藉著彈簧65的彈推力 朝著彈推部56b移動地被保持著。因此，磁鐵66被保持在 與磁感測器67不對向的位置。 門100a、100b更朝著關閉方向移動時，彈推部56a抵 接於桿6 2 ’彈推部5 6 b抵接於桿6 3，使桿6 2藉著彈推部5 6 a 的彈推力抵抗彈簧6 4的彈推力，朝彈推部5 6 b側移動，桿 63藉著彈推部56b的彈推力抵抗彈簧65的彈推力而朝向彈 推部56a側移動。 並且’如第7(b)圖表示，2個門l〇〇a、l〇〇b正常進 行關閉動作’都到達全關閉位置爲止時，磁鐵6 6與磁感測 器67對向。即，使磁鐵66最接近磁感測器67。 在此’磁感測器67在預定範圍（以下，稱磁感測器67 的檢測範圍）內磁鐵66最接近時檢測磁鐵的磁性，對門開 閉裝置的控制部輸出檢測訊號。並且，本變形例中，調整 桿62、63的間隔’使得磁鐵66僅磁鐵66與磁感測器67對向 時（即，磁鐵66最接近磁感測器67時），進入磁感測器67 的檢測範圍。 因此’ 2個門i〇0a、100b僅在2個門都到達全關閉位置 -23- 201111609 爲止時，磁感測器67輸出檢測訊號》 因此，如第6 ( c )圖表示，因門開閉裝置1的故障， 僅一方的門l〇〇a到達全關閉位置爲止，另一方的門l〇〇b在 中途停止的狀態時，磁感測器67和磁鐵66不會彼此對向’ 不會從磁感測器67輸出檢測訊號。 同樣地，如第6 ( d )圖表示，因門開閉裝置1的故障 ，僅門100b到達全關閉位置爲止，門100a在中途停止的狀 態時，磁感測器67和磁鐵66也不會彼此對向，不會從磁感 測器67輸出檢測訊號。 (第1變形例的效果） 如以上說明，第1變形例涉及的門開關1 1是設置可對 基板9(車輛主體）相對移動，一方的門l〇〇a朝向全關閉 位置移動時彈推的桿62(第1受動部）；設置成可對上述 基板9及桿62可相對移動，另一方的門100b朝向全關閉位 置移動時彈推的桿63 (第2受動部）；桿62和桿63的相對 位置形成預定的相對位置，磁鐵66接近檢測範圍內時，輸 出檢測訊號的磁感測器67 (檢測手段）；及彈推桿62及桿 63，使彈推桿62及桿63的相對位置不形成爲上述預定的相 對位置（磁鐵66進入至磁感測器67檢測範圍內的相對位置 )的彈簧64、65 (彈推手段）。在此，上述預定的相對位 置爲桿62與桿63抵抗彈簧64、65的彈推力一邊以設置在雙 開式的2個門l〇〇a、100b的彈推部56a、56b彈推，使該等2 個門100a、10 0b皆移動至全關閉位置爲止時的桿62與桿63 -24- 201111609 的相對位置。 根據此一構成時，僅使得2個門l〇〇a、100b之中的一 方的門移動至全關閉位置，另一方的門未到達全關閉位置 的場合，由於彈簧64、65的彈推力，不會使桿62與桿63的 相對位置形成上述預定的相對位置，因此磁鐵66不會進入 磁感測器67的檢測範圍內，不致有從磁感測器67對控制部 輸出檢測訊號。 藉此，不需增加開關的數量，即可更爲確實檢測雙開 式的門100a、100b是否位於全關閉位置。 (第2變形例） 上述實施形態可如以下變形來加以實施。 第8圖及第9圖是說明上述實施形態之第2變形例的動 作用的模式圖。第2變形例涉及的門開閉裝置在門開關構 成不同的點與上述實施形態不同。因此，僅說明門開關的 構成，針對其他的構成予以省略。此外，與上述實施形態 相同的構件賦予相同符號說明。 如第8圖表示，第2變形例的門開關1 2，具有：固定於 基板9並對該基板9成正交延伸的軸71;與基板9平行配置 ’設置可在軸Ή周圍自由迴轉的扇形板構件的第1迴轉構 件72 ;設置與第1迴轉構件72重疊，可自由迴轉地設置在 軸71周圍的長板形的第2迴轉構件73 ;設置在第1迴轉構件 72與第2迴轉構件73之間的彈簧74 ;設置在第}迴轉構件72 的磁感測器75;設置在第2迴轉構件73的磁鐵76;固定於 -25- 201111609 基板9限制第1迴轉構件72迴轉（第8圖中的箭頭R 1方向的 迴轉）的第1止動件77 ;及固定於基板9限制第2迴轉構件 73迴轉（第8圖中的箭頭R2方向的迴轉）的第2止動件78。 另外，在門100a、10 Ob分別藉支撐構件51a、51b，固 定著與門的開閉方向平行延伸的桿狀的彈推部57a、57b。 第1迴轉構件72在圓弧中心附近部，可自由迴轉被連 結於軸71周圍。並且，在第1迴轉構件72的圓弧形緣部的 附近，且在與位於第1止動件77抵接的直線形緣部相反側 的直線形的緣部附近固定有磁感測器75。 第2迴轉構件73長度是和第1迴轉構件72的半徑大致相 等的長板狀構件，將一端的附近部自由迴轉地連結在軸71 周圍，另一端的附近部固定著磁鐵76。並且，第2迴轉構 件73是構成從軸71到磁鐵76爲止的距離和從軸71到磁感測 器75爲止的距離相等。 彈簧74是將一端抵接於第1迴轉構件72之第1止動件77 的直線形的緣部附近，被固定在第1迴轉構件72半徑方向 的大致中央部。且彈簧74將另一端固定在第2迴轉構件73 長方向的大致中央部。並且，彈簧74彈推第1迴轉構件72 使其朝軸71周圍的一方向（第8圖中逆時針周圍的方向。 以箭頭R1表示。）迴轉，並彈推第2迴轉構件73使其朝著 與該一方向的相反方向（第8圖中順時針周圍的方向。以 箭頭R2表示。）在軸71周圍迴轉。 因此，對第1迴轉構件72及第2迴轉構件73沒有外力（ 彈簧74以外的力）作用的場合，如第8(a)圖表示，第1 -26- 201111609 迴轉構件72被以抵接於第1止動件77的狀態保持著，第2迴 轉構件73則是以抵接於第2止動件78的狀態保持著。 在此狀態下，軸71周圍的方向中，磁感測器75和磁鐵 76爲彼此分離。 並且，隨著門l〇〇a、100b的關閉動作，使彈推部57a 、5 7b朝著關閉方向移動，藉此如第8(b)圖表示，彈推 部57a、57b分別抵接於第1迴轉構件72及第2迴轉構件73的 緣部。具體而言，彈推部57a是抵接於朝第1迴轉構件72的 徑向成直線延伸的緣部。並且，彈推部5 7b是抵接於朝第2 迴轉構件73的長方向成直線延伸的緣部。 另外，使彈推部57a、57b朝著關閉方向移動，藉此將 第1迴轉構件72朝著彈推部57a彈推，抵抗彈簧74的彈推力 ，朝著從第1止動件77離開的方向（第8圖的箭頭R2方向） 在軸7 1周圍迴轉。 並且，第2迴轉構件73爲彈推部57b所彈推，抵抗彈簧 74的彈推力，朝著從第2止動件78離開的方向（第8圖的箭 頭R1方向）在軸71周圍迴轉。 即，彈推部57a、57b朝著關閉方向移動，藉以使磁感 測器75和磁鐵76朝著彼此接近的方向移動。 並且，2個門100a、100b正常地進行關閉動作，2個門 皆到達全關閉位置爲止時，如第8 ( c )圖表示，會使磁感 測器75予磁鐵76重疊。即’使得磁鐵76最接近磁感測器75 〇 在此，磁感測器75在預定的範圍（以下，稱磁感測器 -27- 201111609 75的檢測範圍）內磁鐵76接近時檢測磁鐡的磁氣，對門開 閉裝置的控制部輸出檢測訊號。並且，本變形例中，僅磁 鐵76重疊於磁感測器75時（即，磁鐵76最接近磁感測器75 時），調整第1迴轉構件72與第2迴轉構件73的間隔（予軸 71平行方向的間隔），使磁鐵76進入到磁感測器75的檢測 範圍內。 因此，只在2個門l〇〇a、100b都到達全關閉位置爲止 時，磁感測器75會輸出檢測訊號。 因此，如第9 ( a )圖表示，由於門開閉裝置1的故障 ，僅一方的門1 〇〇a到達全關閉位置爲止，而另一方的門 l〇〇b在中途停止的狀態下，磁感測器75和磁鐵76不會重疊 ，不會從磁感測器75輸出檢測訊號。 同樣，如第9 ( b )圖表示，由於門開閉裝置1的故障 ，僅一方的門1 〇〇b到達全關閉位置爲止，而另一方的門 100a在中途停止的狀態下，磁感測器75和磁鐵76也不會重 疊，不會從磁感測器75輸出檢測訊號。 (第2變形例的效果） (1 ) 如以上說明，第2變形例涉及的門開關1 2是設置可對 於基板9(車輛主體）相對迴轉，具備：一方的門l〇〇a朝 向全關閉位置移動時彈推的第1迴轉構件72 (第1受動部） ;設置成可對基板9及第1迴轉構件72相對迴轉’另一方的 門100b朝向全關閉位置移動時彈推的第2迴轉構件73 (第2 -28- 201111609 受動部）；第1迴轉構件72與第2迴轉構件73的相對位置形 成預定的相對位置’磁鐵76接近檢測範圍內時，輸出檢測 訊號的磁感測器75 (檢測手段）；及彈推第I迴轉構件72 及第2迴轉構件73 ’使第1迴轉構件72與第2迴轉構件73·的 相對位置不形成爲預定的相對位置（磁鐵76進入磁感測器 75之檢測範圍內的位置）的彈簧74 (彈推手段）。在此， 上述預定的相對位置爲第1迴轉構件72與第2迴轉構件73— 邊抵抗彈簧74的彈推力並以設置在雙開式的2個門100a、 100b的彈推部57a、57b彈推，使該等2個門100a、100b皆 移動至全關閉位置爲止時之第1迴轉構件72與第2迴轉構件 7 3的相對位置。 根據此一構成時，2個門100a、100b之僅其中一方的 門移動至全關閉位置爲止，另一方的門未到達全關閉位置 爲止的場合，藉著彈簧74的彈推力，使第]迴轉構件72與 第2迴轉構件73的相對位置不形成爲上述預定的相對位置 ，磁鐵76未進入至磁感測器75的檢測範圍內，因此從磁感 測器75對控制部不會輸出檢測訊號。 因此，不需增加開關的數量，即可更爲確實地檢測出 雙開式的門100a、100b是否皆位於全關閉位置。 (2) 門開關12中，第1迴轉構件"72及第2迴轉構件73被設置 成可自由地迴轉於固定在基板9的軸71 (迴轉軸）周圍， 軸7 1是相對於平板狀的門1 〇 〇 a、1 0 Ob朝垂直方向（車輛的 寬方向）延伸。 -29- 201111609 又，第1迴轉構件72及第2迴轉構件73是形成平板狀， 配置使得和軸71平行的方向形成厚度方向。藉此，在車輛 的寬方向中，可以使門開關1 2所佔的空間爲小空間。 (3) 門開關1 2中，設置在第1迴轉構件72的磁感測器75 ( 第1檢測部）及設置在第2迴轉構件73的磁鐵76 (第2檢測 部）形成預定的位置關係時，即，磁鐵7 6進入到磁感測器 75的檢測範圍內時，該磁感測器75輸出檢測訊號。該磁感 測器75被配置在第1迴轉構件72中，比彈推部57a彈推的位 置更遠離軸71的位置。並且，磁鐵76被配置在第2迴轉構 件73中，比彈推部57a彈推的位置更遠離軸71的位置》 根據此一構成時，與門l〇〇a、100b朝著關閉方向的移 動量（抵接第1迴轉構件72及第2迴轉構件73後的移動量） 比較，磁感測器7 5和磁鐵7 6之間的相對位置的變化量變大 。藉此，可不須提升感測器的精度即可檢測出夾於關閉動 作中的門100a、100b的薄物體。亦即，可以簡易的構成防 止關閉動作中的門l〇〇a、l〇〇b間夾著異物而使得門l〇〇a、 100b不能完全關閉時，因錯誤輸出檢測門100a、100b爲關 閉的檢測訊號。 (第3變形例） 如第2變形例，不僅限於在第1迴轉構件72與第2迴轉 構件73之間設置彈簧74的場合，有可以構成如第10圖所示 -30- 201111609 該構成爲在基板9的第1止動件77的附近’固定有從基 板9突出的第1彈簧保持部81。並在第2止動件78的附近’ 固定有從基板9突出的第2彈簧保持部82。並且，在該第1 彈簧保持部81與第1迴轉構件72之間設置第1彈簧83。該第 1彈簧83拉伸該第1迴轉構件72使第1迴轉構件72接近第1止 動件77。並在第2彈簧保持部82與第2迴轉構件73之間設置 第2彈簧84。該第2彈簧84拉伸該第2迴轉構件73使第2迴轉 構件73接近第2止動件78。 因此，外力（彈簧74以外的力）未作用於第1迴轉構 件72及第2迴轉構件73的場合，如第10(a)圖表示，第1 迴轉構件72被以抵接於第1止動件77的狀態保持著，第2迴 轉構件73則是被以抵接於第2止動件78的狀態保持著。 並且，2個門都到達全關閉位置爲止時，如第1 0 ( b ) 圖表示，磁感測器75與磁鐵76重疊。 如上述，根據第1 0圖記載的構成，也只有在2個門都 到達全關閉位置時，可從門開關1 2輸出檢測訊號。 (第4變形例） 如第3變形例’第1迴轉構件72不僅限於形成扇形的場 合，例如第1 1圖中，如作爲第1迴轉構件72 ’所示，也可以 形成L字型或V字型。此時，可以使第1迴轉構件72’輕量化 ，並可減小該第1迴轉構件7 2 ’迴轉用的所需空間。 並且’如上述第2〜4變形例，第1迴轉構件72的迴轉軸 與第2迴轉構件*73的迴轉軸不僅限於相同之迴轉軸（軸71 -31 · 201111609 )的場合，也可以將第1迴轉構件72的迴轉軸與第2迴轉構 件73的迴轉軸分開，分別設置在不同的位置。 以上，針對本發明的實施形態及變形例已作說明，但 是本發明不限於上述的實施形態及變形例，在申請專利範 圍記載的範圍內可進行種種變更並加以實施。 〔產業上的可利用性〕 本發明可利用於設置在鐵道車輛之檢測雙開式的門關

portion 24 abuts against the pair of electrodes 25, an electronic circuit (detection means) for detecting a signal is output. The limit switch 20 is disposed to be movable in parallel with respect to the substrate 9 in the advancing and retracting direction of the switch box 30 with respect to the lever 22. And, the lever 22 is pushed to the poppet 53a provided at one of the doors 10a, and the switchbox 30 is pushed to the poppet 53b provided at the other door lb, so that the lever 22 With respect to the switch case 30 moving against the elastic force of the spring 23, when both the doors l〇〇a, 100b reach the fully closed position, the lever 22 moves only by the predetermined amount with respect to the switch case 30, forming a pair of plate portions. 24 abuts against a pair of electrodes 25. According to this configuration, it is possible to surely detect whether or not the double-open type door is in the fully closed position by using the limit switch 20 that outputs the detection signal when the lever 22 is moved by a predetermined amount against the opening of the switch case 30 against the elastic force of the spring 23. Therefore, for example, it is also possible to ensure the reliability of the door switch 10 by using a highly reliable limit switch which has been widely used in the past. (4) The door opening and closing device 1 including the door switch 10 described above is provided with a control unit that receives a detection signal output from the door switch 1A. When the control unit receives the detection signal from the door switch 1 ,, the control unit drives the lock device to lock the doors 100a and 100b to the fully closed position. According to this configuration, it can be reliably detected whether the double-opening doors l〇〇a, l〇〇b are in the fully closed position, and the detection signal outputted by the limit switch 20 can be used as the timing for determining the locking of the doors l〇〇a, 100b. Signal used. By this, it is possible to prevent the door 1 〇〇a, 1 〇〇b from driving the locking device due to an error when the full closing position is not reached. -20- 201111609 Further, in the present embodiment, the relative movement amount of the lever Μ to the switch case 3〇 can be increased. In other words, as shown in Fig. 6, when the lever unit 兀 26 is abutted from the urging portion 55a (the sixth (in the figure, the state of the urging portion 55a is indicated by a two-dot chain line), the door 100a reaches the full The relative movement of the door l〇〇a when the position is closed (the state of the sixth figure (b) is not) and the relative movement amount of the lever unit 26 to the switch case 36 (that is, the amount of deformation of the spring 27) The amount is - times the amount of movement of the door 100a. Therefore, the thin object held in the door l00a' 1〇〇b during the closing operation can be detected without increasing the accuracy of the sensor. That is, the door in the closing action 〇〇a ' io 〇 b, to prevent the detection of foreign matter can not completely close the door 100a, 1 〇〇 1) 'output detection detection closed door 1 〇〇 a, 1 〇 0 b detection signal. (First Modification) The above embodiment can be implemented by the following modifications. Fig. 7 is a schematic view for explaining the operation of the modification of the third embodiment of the above embodiment. The door opening and closing device according to the first modification differs from the above embodiment in the point that the door switch configuration is different. Therefore, only the configuration of the door switch will be described, and other configurations will be omitted. The same components as those in the above embodiment are denoted by the same reference numerals. As shown in Fig. 7, the door switch 1 of the first modification includes a switch case 61, and two poles 62 and 63 on the proximal end side of the switch case 61 are disposed in the switch case 61. Springs 64 and 65 between the base end and the inner surface of the switch case 61; a magnet 66 fixed to one of the rods 62; and a magnetic sensor 67 fixed to the other rod 63. -21 - 201111609 In addition, in the opening and closing direction of the door, the spring pushing portions 5 6 a and 5 6 b are disposed at positions facing the rods 62 and 63, respectively. The poppet portions 5 6 a ' 5 6b are coupled to the doors 100a and 100b, respectively, and move as the doors 100a and 10b move. The switch box 61 is directly fixed to the substrate 9. That is, the switch box 61 is fixed so as not to move relatively to the vehicle body. The rod 62 is configured such that its front end protrudes from the switch case 61 and the base end is located in the switch case 61. The rod 62 is provided to be freely advanced and retractable in the axial direction with respect to the switch box 61. Further, the advancing and retracting direction of the rod 62 is parallel to the opening and closing direction of the door. A spring 64 is disposed between the rod 62 and the switch case 61. The spring 64 is a push rod 62 from the base side toward the front end side. Further, the rod 62 is fixed with a magnet 66 at an intermediate portion in the axial direction. The magnet 66 is fixed to the rod 62 opposite to the side of the rod 63. Further, as the door l〇〇a is closed, the poppet portion 56a is moved in the closing direction, whereby the front end of the push rod 62 is configured by the spring pushing portion 56a. The rod 63 is disposed such that its front end projects from the switch case 61 in the opposite direction to the rod 62 with its base end located in the switch case 61. The rod 63 is disposed to advance and retreat toward the axial direction with respect to the switch box 61. Further, the advancing and retracting direction of the lever 63 is parallel to the opening and closing direction of the door. Further, the rod 63 is disposed at substantially the same position as the rod 62 in the direction orthogonal to the substrate 9 (the depth direction of the paper in Fig. 7). That is, 'from the direction parallel to the vertical direction, the rods 6 2, 6 3 are disposed such that the central axis of the rod 6 2 and the central axis of the rod 6 3 are in the same linear position. A spring 65 is disposed between the rod 63 and the switch case 61. This spring 65 pushes the rod 63 from the proximal end side toward the distal end side. -22- 201111609 Further, the rod 63 is fixed with a magnetic sensor 67 in the axial middle portion. The magnetic sensor 67 is fixed to the rod 63 opposite to the side of the rod 62. Then, as the door l〇〇b is closed, the poppet portion 56b is moved in the closing direction, whereby the front end of the push rod 63 is configured by the spring pushing portion 56b. As shown in Fig. 7(a), in a state where the levers 62, 63 are not pushed by the spring pushing portions 56a, 56b, the lever 62 is moved by the spring force of the spring 64 to move on the side of the spring pushing portion 56a. Hold, the rod 63 is held by the spring force of the spring 65 toward the projecting portion 56b. Therefore, the magnet 66 is held at a position that is not opposed to the magnetic sensor 67. When the doors 100a, 100b are moved further in the closing direction, the spring pushing portion 56a abuts against the rod 6 2 'the pushing portion 5 6 b abuts against the rod 6 3 , so that the rod 6 2 is ejected by the elastic portion 5 6 a The spring force of the thrust resisting spring 6 4 is moved toward the elastic pushing portion 5 6 b side, and the lever 63 is moved toward the elastic pushing portion 56 a side by the elastic thrust of the spring pushing portion 56 b against the spring force of the spring 65 . Further, as shown in Fig. 7(b), when the two doors l〇〇a and lb are normally turned off, the magnets 6 are opposed to the magnetic sensor 67 when they reach the fully closed position. That is, the magnet 66 is brought closest to the magnetic sensor 67. Here, the magnetic sensor 67 detects the magnetism of the magnet when the magnet 66 is closest in a predetermined range (hereinafter, referred to as the detection range of the magnetic sensor 67), and outputs a detection signal to the control unit of the door opening and closing device. Further, in the present modification, the interval "of the adjustment levers 62, 63" causes the magnet 66 to enter the magnetic sensor only when the magnet 66 is opposed to the magnetic sensor 67 (that is, when the magnet 66 is closest to the magnetic sensor 67). The detection range of 67. Therefore, when the two doors i0a and 100b reach the fully closed position -23-201111609, the magnetic sensor 67 outputs the detection signal. Therefore, as shown in the sixth (c), the door is opened and closed. In the failure of the device 1, only the one door l〇〇a reaches the fully closed position, and the other door l〇〇b is stopped in the middle, the magnetic sensor 67 and the magnet 66 do not oppose each other' The detection signal is output from the magnetic sensor 67. Similarly, as shown in Fig. 6(d), due to the failure of the door opening and closing device 1, only the door 100b reaches the fully closed position, and the magnetic sensor 67 and the magnet 66 do not each other when the door 100a is stopped in the middle. In the opposite direction, the detection signal is not output from the magnetic sensor 67. (Effect of the first modification) As described above, the door switch 1 1 according to the first modification is provided so that the substrate 9 (vehicle body) can be relatively moved, and when one of the doors 10a moves toward the fully closed position, the door is pushed. a lever 62 (first receiving portion); a lever 63 (second receiving portion) that is rotatable when the other door 100b is relatively movable toward the fully closed position; the lever 62 and the rod 62 are relatively movable The relative position of the rod 63 forms a predetermined relative position, and when the magnet 66 is within the detection range, the magnetic sensor 67 (detection means) for outputting the detection signal; and the push rod 62 and the rod 63 are caused to make the push rod 62 and the rod 63 The relative positions are not formed as springs 64, 65 (elastic means) of the predetermined relative position (the relative position of the magnet 66 into the detection range of the magnetic sensor 67). Here, the predetermined relative position is such that the rod 62 and the rod 63 are pushed against the spring force of the springs 64 and 65 by the spring pushing portions 56a and 56b provided in the two open doors 2a and 100b. The relative position of the rod 62 and the rod 63 - 24 - 201111609 when the two doors 100a, 10 0b are moved to the fully closed position. According to this configuration, only one of the two doors 10a, 100b is moved to the fully closed position, and when the other door does not reach the fully closed position, due to the spring force of the springs 64, 65, The relative position of the rod 62 and the rod 63 is not formed to the above-described predetermined relative position, so that the magnet 66 does not enter the detection range of the magnetic sensor 67, and the detection signal is not output from the magnetic sensor 67 to the control unit. Thereby, it is possible to more reliably detect whether the double-open doors 100a, 100b are in the fully closed position without increasing the number of switches. (Second Modification) The above embodiment can be implemented by the following modifications. Fig. 8 and Fig. 9 are schematic views for explaining the action of the second modification of the above embodiment. The door opening and closing device according to the second modification is different from the above embodiment in that the door switch is different in configuration. Therefore, only the configuration of the door switch will be described, and other configurations will be omitted. The same members as those in the above embodiment are denoted by the same reference numerals. As shown in Fig. 8, the door switch 12 of the second modification has a shaft 71 that is fixed to the substrate 9 and extends orthogonally to the substrate 9, and is disposed in parallel with the substrate 9 so as to be rotatable around the shaft. The first turning member 72 of the sector-shaped plate member is provided with a long-plate-shaped second turning member 73 that is rotatably provided around the shaft 71 so as to be overlapped with the first turning member 72, and is provided in the first turning member 72 and the second turning member. a spring 74 between the members 73; a magnetic sensor 75 provided on the first rotating member 72; a magnet 76 provided in the second rotating member 73; fixed at -25-201111609, the substrate 9 restricts the rotation of the first rotating member 72 (the The first stopper 77 of the rotation in the direction of the arrow R1 in the figure 8; and the second stopper 78 fixed to the substrate 9 to restrict the rotation of the second rotation member 73 (the rotation in the direction of the arrow R2 in Fig. 8) . Further, in the doors 100a and 10BB, the rod-shaped projecting portions 57a and 57b extending in parallel with the opening and closing direction of the door are fixed by the support members 51a and 51b, respectively. The first turning member 72 is rotatably connected around the shaft 71 in the vicinity of the center of the arc. Further, in the vicinity of the arcuate edge portion of the first turning member 72, the magnetic sensor 75 is fixed in the vicinity of the linear edge portion on the opposite side to the linear edge portion that is in contact with the first stopper 77. . The length of the second turning member 73 is a long plate-like member having a length substantially equal to the radius of the first turning member 72, and the vicinity of one end is rotatably coupled around the shaft 71, and the magnet 76 is fixed to the vicinity of the other end. Further, the second rotating member 73 has a distance from the shaft 71 to the magnet 76 and a distance from the shaft 71 to the magnetic sensor 75. The spring 74 abuts against the vicinity of the linear edge portion of the first stopper 77 of the first rotating member 72, and is fixed to the substantially central portion in the radial direction of the first rotating member 72. Further, the spring 74 fixes the other end to a substantially central portion in the longitudinal direction of the second rotating member 73. Further, the spring 74 pushes the first turning member 72 to rotate in one direction around the shaft 71 (in the direction around the counterclockwise direction in Fig. 8 as indicated by an arrow R1), and pushes the second turning member 73 toward The direction opposite to the one direction (the direction around clockwise in Fig. 8 is indicated by an arrow R2) is rotated around the shaft 71. Therefore, when the first rotating member 72 and the second rotating member 73 do not have an external force (a force other than the spring 74), as shown in Fig. 8(a), the first -26-201111609 rotating member 72 is abutted. The state of the first stopper 77 is maintained, and the second turning member 73 is held in contact with the second stopper 78. In this state, in the direction around the shaft 71, the magnetic sensor 75 and the magnet 76 are separated from each other. Then, as the doors l〇〇a and 100b are closed, the spring pushing portions 57a and 57b are moved in the closing direction. As shown in Fig. 8(b), the spring pushing portions 57a and 57b are respectively abutted. The edge of the first turning member 72 and the second turning member 73. Specifically, the spring pushing portion 57a is in contact with an edge portion that extends in a straight line in the radial direction of the first turning member 72. Further, the poppet portion 57b abuts against an edge portion that extends in a straight line toward the longitudinal direction of the second turning member 73. Further, the spring pushing portions 57a and 57b are moved in the closing direction, whereby the first turning member 72 is pushed toward the spring pushing portion 57a, and is moved away from the first stopper 77 against the spring force of the spring 74. The direction (the direction of the arrow R2 in Fig. 8) is rotated around the shaft 7 1 . Further, the second turning member 73 is pushed by the spring pushing portion 57b, and is rotated around the shaft 71 in a direction away from the second stopper 78 (direction of the arrow R1 in Fig. 8) against the spring force of the spring 74. That is, the urging portions 57a, 57b are moved in the closing direction, whereby the magnetic sensor 75 and the magnet 76 are moved in the direction in which they approach each other. Further, when the two doors 100a and 100b are normally closed, and when both of the doors reach the fully closed position, as shown in Fig. 8(c), the magnetic sensor 75 is superimposed on the magnet 76. That is, 'the magnet 76 is closest to the magnetic sensor 75. Here, the magnetic sensor 75 detects the magnetic yoke when the magnet 76 approaches in a predetermined range (hereinafter, the detection range of the magnetic sensor -27-201111609 75). The magnetic gas outputs a detection signal to the control unit of the door opening and closing device. Further, in the present modification, only when the magnet 76 is superposed on the magnetic sensor 75 (that is, when the magnet 76 is closest to the magnetic sensor 75), the interval between the first rotating member 72 and the second rotating member 73 is adjusted (pre-axis) The interval of 71 parallel directions causes the magnet 76 to enter the detection range of the magnetic sensor 75. Therefore, the magnetic sensor 75 outputs a detection signal only when both of the doors l〇〇a, 100b reach the fully closed position. Therefore, as shown in Fig. 9 (a), due to the failure of the door opening and closing device 1, only one of the doors 1 〇〇 a reaches the fully closed position, and the other door l 〇〇 b stops in the middle, The sensor 75 and the magnet 76 do not overlap and the detection signal is not output from the magnetic sensor 75. Similarly, as shown in Fig. 9 (b), due to the failure of the door opening and closing device 1, only one of the doors 1 〇〇b reaches the fully closed position, and the other door 100a is stopped halfway, the magnetic sensor The 75 and the magnet 76 also do not overlap, and the detection signal is not output from the magnetic sensor 75. (Effects of the second modification) (1) As described above, the door switch 12 according to the second modification is provided so that the substrate 9 (vehicle body) can be relatively rotated, and one of the doors 10a is completely closed. The first turning member 72 (first receiving portion) that is pushed when the position is moved; the second turning member that is slidable when the other member's door 100b is moved toward the fully closed position with respect to the rotation of the substrate 9 and the first turning member 72 The member 73 (the second -28-201111609 receiving portion); the magnetic sensor 75 that outputs the detection signal when the relative position of the first turning member 72 and the second turning member 73 forms a predetermined relative position 'the magnet 76 is within the detection range. (detection means); and the first turning member 72 and the second turning member 73' are pushed so that the relative positions of the first turning member 72 and the second turning member 73 are not formed at predetermined relative positions (the magnet 76 enters the magnetic sensing) The spring 74 (the spring pushing means) of the position within the detection range of the device 75). Here, the predetermined relative position is such that the first turning member 72 and the second turning member 73 are biased against the spring force of the spring 74 and are pushed by the pushing portions 57a and 57b provided in the two doors 100a and 100b of the double opening type. The relative positions of the first turning member 72 and the second turning member 73 when the two doors 100a and 100b are moved to the fully closed position. According to this configuration, when only one of the two doors 100a and 100b moves to the fully closed position and the other door does not reach the fully closed position, the first swing is caused by the spring force of the spring 74. The relative position of the member 72 and the second turning member 73 is not formed at the predetermined relative position, and the magnet 76 does not enter the detection range of the magnetic sensor 75. Therefore, the control unit does not output a detection signal from the magnetic sensor 75. . Therefore, it is possible to more reliably detect whether the double-open doors 100a, 100b are all in the fully closed position without increasing the number of switches. (2) In the door switch 12, the first turning member "72 and the second turning member 73 are provided so as to be freely rotatable around the shaft 71 (rotary shaft) fixed to the substrate 9, and the shaft 71 is opposed to the flat plate The door 1 〇〇 a, 1 0 Ob extends in the vertical direction (the width direction of the vehicle). -29-201111609 Further, the first turning member 72 and the second turning member 73 are formed in a flat shape, and are disposed such that a direction parallel to the shaft 71 forms a thickness direction. Thereby, in the width direction of the vehicle, the space occupied by the door switch 12 can be made small. (3) In the door switch 1 2, the magnetic sensor 75 (first detecting unit) provided in the first rotating member 72 and the magnet 76 (second detecting unit) provided in the second rotating member 73 form a predetermined positional relationship When the magnet 76 enters the detection range of the magnetic sensor 75, the magnetic sensor 75 outputs a detection signal. The magnetic sensor 75 is disposed in the first turning member 72 at a position farther from the shaft 71 than the position of the spring pushing portion 57a. Further, the magnet 76 is disposed in the second turning member 73, and is located farther from the shaft 71 than the position of the spring pushing portion 57a. According to this configuration, the movement of the door doors 10a, 100b in the closing direction is performed. The amount (the amount of movement after the first turning member 72 and the second turning member 73 is abutted) is compared, and the amount of change in the relative position between the magnetic sensor 75 and the magnet 76 is increased. Thereby, the thin object sandwiched between the doors 100a, 100b in the closing operation can be detected without raising the accuracy of the sensor. In other words, it is possible to easily prevent the door 10a, 100b from being completely closed when the door is closed between the doors l〇〇a and lb in the closing operation, and the detection gates 100a and 100b are closed due to the erroneous output. Detection signal. (Third Modification) The second modification is not limited to the case where the spring 74 is provided between the first rotating member 72 and the second rotating member 73, and may be configured as shown in Fig. 10 - 2011-11609. The first spring holding portion 81 that protrudes from the substrate 9 is fixed in the vicinity of the first stopper 77 of the substrate 9. A second spring holding portion 82 projecting from the substrate 9 is fixed in the vicinity of the second stopper 78. Further, a first spring 83 is provided between the first spring holding portion 81 and the first rotating member 72. The first spring 83 extends the first turning member 72 to bring the first turning member 72 closer to the first stopper 77. A second spring 84 is provided between the second spring holding portion 82 and the second rotating member 73. The second spring 84 extends the second turning member 73 to bring the second turning member 73 closer to the second stopper 78. Therefore, when the external force (force other than the spring 74) does not act on the first turning member 72 and the second turning member 73, as shown in Fig. 10(a), the first turning member 72 is brought into contact with the first stop. The state of the member 77 is maintained, and the second turning member 73 is held in contact with the second stopper 78. Further, when both the doors have reached the fully closed position, as shown in the figure 10 (b), the magnetic sensor 75 overlaps with the magnet 76. As described above, according to the configuration described in Fig. 10, the detection signal can be output from the door switch 12 only when both of the doors reach the fully closed position. (Fourth Modification) As the third modification, the first rotation member 72 is not limited to the case of forming a sector shape. For example, in the first diagram, as shown in the first rotation member 72', an L-shape or a V may be formed. Font type. At this time, the first turning member 72' can be made lighter, and the space required for the rotation of the first turning member 7 2 ' can be reduced. In the above-described second to fourth modifications, the rotation axis of the first turning member 72 and the turning axis of the second turning member *73 are not limited to the same rotating shaft (shaft 71 - 31 · 201111609 ), and the The rotary shaft of the rotary member 72 is separated from the rotary shaft of the second rotary member 73, and is disposed at different positions. The embodiment and the modifications of the present invention have been described above, but the present invention is not limited to the above-described embodiments and modifications, and various modifications and improvements can be made without departing from the scope of the invention. [Industrial Applicability] The present invention can be applied to a railway vehicle door opening and closing device for a railway vehicle, which is provided for a double-opening door closing for a railway vehicle, and a double-opening door opening and closing device.
