200817219 延伸的4支滑動軌道8 3 a、8 3 b、8 3 c、8 3 d。平行支承構件 81a、81b、81c、81d是分別對應於滑動軌道83a、83b、 83c、83d，而支承成可沿著該滑動軌道滑動。具體地說， 滑動軌道8 3 a〜8 3 d，在側面形成有延伸於長度方向的溝， 且構成：形成於平行支承構件8 1 a〜8 1 d之側面的凸部可 一邊受到該溝的支承並一邊沿著該滑動軌道移動。再者， 可在平行支承構件8 1 a〜8 1 d的側面組裝凸輪從動件等的 導件滾子，並促使其沿著溝移動。其結果形成：踏板7及 框架8可藉由後述馬達單元1 7的驅動，而從月台1 〇〇側 朝車輛側進退。 此外，在殼體2内靠近車輛側之相反側端部的位置， 可限制框架8之進退移動的鎖定機構20次設置於座板3。 該鎖定機構20，是藉由譬如以電磁方式來執行卡合扣件的 突出、縮回，進而與一體形成於框架8的卡合部分8 a卡 合，而可限制：在推進狀態下框架8朝退避方向的移動； 及在退避狀態下框架8朝推進方向的移動。 此外，在殻體2的座板3設置有頂板支承體9，該頂 板支承體9可透過頂板6而支承朝垂直方向下方作用的荷 重。如第4圖及第5圖所示，頂板支承體9是配置在殼體 2内靠近車輛側之相反側端部的位置，並配置成：以平行 於踏板7之進退方向的方向做爲長度方向。該頂板支承體 9是以：兩端是利用螺栓等固定於座板3，而中央部是從 座板3上浮並抵接於頂板6後加以支承的方式，形成彎曲 成「C」字狀的板狀構件。框架8的垂直支承構件8 2 b， -12- 200817219 82d，82f是位於頂板支承體9與座板3之間，而可在進退 方向上移動。 接下來，說明用來使踏板7朝車輛側進退的構造。如 弟2圖及弟3圖所不’在構成殼體2的座板3之車輛側的 相反側端部附近，固定有馬達單元1 7 (驅動手段）。該馬 達單元1 7是由：電動馬達；及可對該馬達軸的旋轉減速 並增強扭矩的減速機所一體構成，該驅動輸出軸（驅動 軸）是配置成面向垂直方向。在該驅動輸出軸固定有小齒 輪1 8 (驅動手段）。另外，在固定有踏板7之框架8的平 行支承構件8 1 e，固定有齒條1 9 (驅動手段）以便於與小 齒輪1 8嚙合，藉由驅動電動馬達來促使小齒輪1 8旋轉， 可使踏板7朝車輛進退移動。 如此一來，由馬達單元1 7、小齒輪1 8、齒條1 9等所 構成的驅動手段，可透過框架8促使踏板7進退移動，並 配置在靠近殼體2之車輛側的相反側端部，而位於殼體2 内較導引溝6a更靠近車輛側的相反側。亦即，在設置於 殼體2内的場合中，於上下方向需要較大空間的驅動手 段，不會配置在較導引溝6 a更靠近車輛側的位置（請參 考第6圖及第7圖）。如此一來，可在較導引溝6a更靠 近車輛側之位置的殼體2内確保空間。 此外，該電動馬達可構成：在驅動停止時，可將外力 對驅動輸出軸所造成的旋轉予以制動之具有制動器的馬 達。如此一來，在停電、異常時，可將踏板7保持在停止 位置。藉此，可防止踏板7意外地產生突出、縮回的動 -13- 200817219 作，並可提高乘客的安全性。 再者’驅動手段並不侷限於由上述齒條與小齒輪機構 所構成的手段，也可以是：藉由採用電動馬達使滑輪旋 轉’並促使捲繞於滑輪的皮帶行走，而使固定於皮帶的框 架進退移動的構造。 在構成殼體2的座板3設置有··退避位置停止器 11a、12a;及推進位置停止器lib、12b。此外，在座板3 設置有：退避位置偵測感應器1 3 a及推進位置偵測感應器 13b。上述的感應器譬如可採用接近開關（pr0Ximity switch)，可當垂直支承構件82b靠近至特定位置爲止之 際，停止電氣馬達的旋轉而停止框架8的移動。藉由退避 位置停止器1 la、12a及推進位置停止器1 lb、12b來限制 垂直支承構件82b、8 2f之進退方向的移動，可防止因錯 誤的動作而導致朝推進方向及退避方向的過量移動。 舉例來說，在踏板7移動至退避方向的場合中，如第 2圖及第5圖（a)所示，是在垂直支承構件82b、8 2f抵接 於退避位置停止器1 1 a、1 2a的狀態下停止。此外，在踏 板7移動至推進方向的場合中，是如第3圖及第5圖（b)所 示，在垂直支承構件82b、82f抵接於推進位置停止器 1 1 b、1 2 b的狀態下停止。 在此，框架8是配置成接近殼體2的底板5，並形成 可在殻體2内的框架8上方確保空間。此外，是以踏板7 從導引溝6 a僅至車輛側進退移動的長度平行於進退方向 延伸，踏板7並不會以橫越過導引溝6 a下部的方式移 200817219 動。因此，基於上下車乘客容易步行的觀點，藉由設置成 上表面位在略水平於頂板6之位置的踏板7之進退移動， 將不會減少導引溝6a下方的空間，而可輕易地確保導引 溝6a下方的空間。 如第4圖、第5圖所示，在本實施形態中形成：可利 用導引溝6a下方附近的空間，來收容設置於月台100的 月台門裝置200之門滑動機構的局部，也就是指防振配件 2 02。防振配件202是固定於門201的下端，且通過導引 溝6a，將囀動支承的滾子部配置於殼體2内。接著，伴隨 著門20 1的開閉，譬如以延著設置於殼體2的軌道（圖面 中未顯示）之類的方式，而在殼體2内於延著導引溝6a 的方向上移動。藉此，可防止門20 1的振動。 如此一來，本實施形態的踏板裝置1，可與需要溝的 月台門裝置200 —起使用於月台100上。接著，由於踏板 裝置1的殻體2内可收容月台門裝置200之門滑動機構的 局部，故可更近一降低月台門裝置2 0 0設計中對空間性的 限制。如此一來，可藉由踏板裝置1來防止乘客跌落於月 台1 0 〇與停靠車輛之間，並可藉由能與踏板裝置1同時使 用之月台門裝置200的功能而成爲更完善的裝置。如以上 所述，並不侷限於設置門之防止扣件的場合，舉例來說， 也可以在踏板裝置內的空間設置月台門裝置之門的驅動皮 帶等。 此外，頂板支承體9是設置成：殼體2内較導引溝6 a 更位於車輛側的相反側，除了可將殼體2的強度保持成： -15- 200817219 上下車乘客在頂板6上通行，殼體2也不會受到破壞的程 度，還能使殼體2内車輛側附近的空間變的更寬闊。 此外，框架8的車輛側端部，是由突出於車輛側的平 行支承構件8 1 a〜8 1 d所形成。亦即，位於框架8之平行 支承構件8 1 a〜8 1 d的車輛側端部並非由垂直支承構件所 支承。因此，在框架8之車輛側的端部，在作用朝向垂直 於踏板7之進退方向的方向，也就是指平行於踏板7之上 表面的方向（亦即，車輛的進入方向）的外力的場合中， 是形成框架8是更容易變形的構造。藉此，在踏板7的推 進狀態下，即使萬一車輛衝撞踏板7時，也能藉由框架8 產生變形或破壞，而由框架部分來吸收衝撃，可抑制車輛 或踏板裝置1之電動馬達等驅動手段的損傷。 此外，在第4圖（a)所示的剖面中，支承著平行支承構 件最靠近車輛側端部之位置的垂直支承構件82c是形成： 在踏板7的退避狀態下接近頂板支承體9。此外，在第5 圖（a)所示的剖面中，支承著平行支承構件最靠近車輛側端 部之位置的垂直支承構件8 2 a是形成：在踏板7的退避狀 態下接近頂板支承體9。同樣地，即使是第2圖中位於框 架8右側的垂直支承構件82e，也是配置成接近頂板支承 體9。 這樣一來，由於較頂板支承體9更位於車輛側的垂直 支承構件是配置成：在踏板7退避至殼體2内的狀態下接 近頂板支承體9，故平行支承構件被垂直支承構件所支承 的位置可以更靠近車輛側的相反側。此時，框架8形成： -16- 200817219 支承位置更靠近車輛側之相反側的懸臂狀態的框形狀。因 此，當在框架8的車輛側端部作用朝向車輛之進入方向的 外力的場合中，框架8變得更容易變形。藉此，可大幅增 加框架部分吸收衝撃吸收的効果，即使在萬一車輛衝撞踏 板7的場合中，也能抑制車輛等的損傷。在該場合中，由 於頂板支承體9不會妨礙框架8的進退移動，且能將頂板 6支承在更靠近車輛側端部的位置，因此相對於上下車乘 客步行於頂板6上時所作用的荷重，能更進一步提高踏板 裝置1的強度。 此外，踏板7可以是譬如由鋁所形成的蜂巢構造。在 該場合中，可提高踏板7的衝撃吸收性。如此一來，在車 輛接觸於踏板7的場合中，可防止踏板裝置1整體受到破 壞。此外，也能既保有特定剛性又形成輕量化，而使支承 踏板7的框架8形成更輕薄的形狀。 以上，雖然是針對本發明的實施形態所進行的說明， 但是本發明並不侷限於上述的實施形態，只要在申請專利 範圍所記載的範圍之內，可以做出各種的變更並據以實 施。 【圖式簡單說明】 第1圖··爲設置有本發明實施形態之月台用踏板裝置 的月台的整體槪略圖。 第2圖：爲第1圖所示之踏板裝置的俯視圖，是顯示 踏板對車輛形成退避狀態的圖。 -17- 200817219 第3圖：爲第1圖所示之踏板裝置的俯視圖，是顯示 踏板對車輛形成推進狀態的圖。 第4圖：爲第2圖及第3圖所示之踏板裝置的A-A剖 面方向圖的示意圖。 第5圖：爲第2圖及第3圖所示之踏板裝置的B-B剖 面方向圖的示意圖。 第6圖：爲第3圖所示之踏板裝置的C-C剖面方向圖 的示意圖。 第7圖：爲第3圖所示之踏板裝置的D-D剖面方向圖 的示意圖。 第8圖：爲設置有本發明實施形態的月台用踏板裝置 與屏蔽式月台門裝置之月台的全體槪略圖。 【主要元件符號說明】 1 :月台用踏板裝置 2 :殼體 6 :頂板 6a :導引溝 7 :踏板 8 :框架 9 :頂板支承體 1 7 :馬達單元（驅動手段） 1 8 :小齒輪（驅動手段） 1 9 :齒條（驅動手段） -18- 200817219 8 1 a〜8 1 e :平行支承構件（框架） 82a〜82f :垂直支承構件（框架） 100 :月台 200 :月台門裝置 202 :防振配件 -19-200817219 IX. Description of the Invention [Technical Field] The present invention is a pedal device for preventing a passenger from falling on a platform and a parking vehicle. [Prior Art] Conventionally, the pedal device for preventing passengers from falling on the platform and docking the vehicle platform is known as disclosed in Patent Document 1. The fall prevention device of the platform disclosed in Patent Document 1 is a device in which the movable body moves in parallel from the platform side toward the vehicle side and advances, and the gap between the table and the vehicle. More specifically, as described in this document, the central portion and both end portions of the drop prevention I are fixed to the plates 23 and 24, and the structure is supported by the guides 48 and 49 of the plurality of seat plates 46 and 47. . The fall prevention member 21 is moved forward and backward toward the vehicle by the drive mechanisms 30, 24 provided at the center of the fall prevention device. In addition, in recent years, the platform door of PSD (Platform Door) or APG (Automatic Platform Platform, or semi-high platform screen door) has been installed on the platform. In the above-mentioned device, by forming a guide groove or a specific space extending along the platform on the platform, a vibration-proof fitting that can slide the groove or a drive belt of the door panel can be formed. And space, and become more capable. Between the months of the public, the slabs of the slabs are removed from the slabs 2 1 and then placed through the screens of the screens; the required door panels are placed along the upper -4-200817219 [Patent Document 1] In the case of the fall prevention device described in Patent Document 1, there is no unnecessary space in the device. Therefore, in the case where the fall prevention device is provided on the platform, the space for forming the groove on the platform disappears, and it is difficult to use the dock door device which is required to have the groove on the platform as described above. In view of the above problems in practical use, it is an object of the present invention to provide a pedal device for a platform that can be used together with a dock door device that has a groove on the platform. [Means for Solving the Problem] The present invention is a platform pedal device for preventing passengers from falling between a platform and a parked vehicle. Further, the pedal device for a platform of the present invention has several features as described below in order to achieve the above object. In other words, the pedal device for a platform of the present invention can have the following features either individually or by appropriate combination. A first feature of the platform pedal device of the present invention for achieving the above object is a platform pedal device for preventing a passenger from falling between a platform and a parking vehicle, and has a casing that can be buried. And a pedal that is supported by the housing; and a driving means capable of relatively moving the housing in such a manner that the pedal is advanced or retracted toward the vehicle side, and the housing is provided a top plate, the top plate is formed on the platform when the casing is buried -5 - 1717219; and a guiding groove is formed on the top plate and extends parallel to the direction along the platform, in the foregoing The upper portion of the casing has a space in the vicinity of the guide groove that can accommodate a part of the door sliding mechanism of the platform door device installed on the platform. According to the above configuration, it can be used together with a dock door device that requires a groove on the platform. Then, since the portion of the door sliding mechanism of the dock door device can be housed in the casing of the platform for the platform, the space limitation in the design of the door device can be further reduced. In this way, passengers can be prevented from falling between the platform and the parked vehicle, and a more complete device can be realized by the function of the platform door device used simultaneously with the platform pedal device. Further, according to a second aspect of the pedal device for a platform of the present invention, the frame-shaped frame is further supported by the casing, and the pedal is fixed to an end portion on the vehicle side. The driving means is configured to move the pedal forward and backward through the frame, and is disposed on an opposite side of the vehicle side of the casing, and is located on the opposite side of the vehicle from the guide groove in the casing. The frame is disposed to be close to the lower surface of the casing, and extends in a direction parallel to the forward and backward directions by a length in which the pedal moves forward and backward from the guiding groove only toward the vehicle side. According to the above configuration, the driving means is not provided at a position closer to the vehicle side than the guiding groove. In this way, the space inside the casing at a position closer to the vehicle side than the guide groove can be ensured. In addition, space can be secured above the frame within the housing. Further, since the pedal does not move in a manner to traverse the lower portion of the guide groove, the space below the guide groove is not lowered by the pedal, and the space under the guide groove can be easily secured. -6-200817219 In a third aspect of the pedal device for a platform according to the present invention, the driving means includes: a motor; and a pinion gear that rotates integrally with a drive shaft of the motor; and a rack, the rack The motor is provided with a brake provided in the frame, and the motor is a motor having a brake. When the drive is stopped, the rotation of the drive shaft caused by an external force can be braked. According to the above configuration, the pedal can be held in the stop position in the event of a power failure or an abnormality. In this way, the pedal does not accidentally form a protruding and retracting motion to improve the safety of the passenger. Further, according to a fourth aspect of the pedal device for a platform of the present invention, the frame has a plurality of parallel supporting members extending in parallel to the advancing and retracting direction, and the end portion on the vehicle side is formed by the parallel supporting members protruding from the vehicle side. According to the above configuration, when the vehicle side end portion of the frame acts: a direction perpendicular to the advancing and retracting direction of the pedal, that is, an external force toward a direction parallel to the upper surface of the pedal (the entering direction of the vehicle), due to the parallel supporting member The side end of the vehicle is not limited, so the frame can be more easily deformed. As a result, in the stopped state in which the pedal is pushed toward the vehicle side, even if the vehicle collides with the pedal, damage to the vehicle or the drive device can be suppressed by deformation or destruction of the frame. Further, according to a fifth aspect of the pedal device for a platform of the present invention, the frame has a plurality of vertical support members extending in a direction perpendicular to the advancing and retracting direction and connected to the plurality of parallel supporting members, and the housing is supported by the housing The body further includes a top plate support body that supports the top plate in a vertical direction, the top plate support body is located on the opposite side of the vehicle guide side from the guide groove, and is located closer to the vehicle side than the top plate support body. The vertical support member of the 200817219 is arranged to approach the top plate support body when the pedal is retracted from the shell state. According to the above configuration, the support strength of the top plate can be confirmed by the top plate supporting member, and the support position of the support member by the vertical support member can be closer to the opposite side of the vehicle side. This is the shape of the cantilever that forms the opposite side of the support side closer to the vehicle side. Therefore, in the case where an external force toward the vehicle direction is applied to the vehicle side end portion of the frame, the frame can be more easily deformed. For example, even if the vehicle hits the pedal, it can be deformed by the frame or damage to the vehicle or the drive unit. [Embodiment] Hereinafter, the best mode for carrying out the invention will be described. Fig. 1 is a schematic overall view of a platform on which a platform for a platform according to an embodiment of the present invention (hereinafter referred to as a pedal device) is installed. The state in which the movable barrier type dock door device 200 (APG) pedal device 1 is used together is shown. As shown in Fig. 1, the platform unit 1 is installed to allow the pedal 7 to advance and retreat toward the vehicle side. As a result, passengers fall between the platform and the parked vehicle. Next, on the upper surface of the pedal device 1, a guide groove 6a extending along the platform is formed on the lower side of the pair of doors 201, 201 located on the month 200. On the other hand, when 2 〇 2 (shown in Figs. 4 and 5 to be described later) fixed to the lower end of the door 201 is inserted into the guide body to be perpendicular to the vertical direction, the frame state of the frame enters the frame. The destruction and the test surface into the pedal device 1 is a step with the platform for 1 0 0, which can prevent the side of the door device 100 from being in the state of 200817219 of the anti-vibration fitting groove 6a. 6a opens and closes the door 201. Thereby, the door 201 can be prevented from vibrating toward the front and rear (perpendicular to the direction of the guide groove 6a), and the opening and closing of the door can be stably performed.

The pedal device 1 is configured to be disposed in the recess 10a, and the recess 100a is formed at the end of the platform 100 facing the vehicle (refer to FIG. 4, FIG. 5-9 - 200817219). The recessed portion 100a is formed by cutting a rectangular shape such as a platform loo formed of concrete. The bottom surface of the recessed portion 1 〇〇a serves as an installation surface for providing the pedal device 1, and constitutes an open upper surface and a vehicle side. The pedal device 1 has a housing 2 having: a plurality of flat plate-shaped seat plates 3; and a side plate 4 forming a side surface of three sides other than the face facing the vehicle; and a bottom plate 5, the bottom plate 5 is fixed to the recessed portion 10a by a ground anchor or the like; and the top plate 6, which is a tread surface of the passenger getting on and off (not shown in FIGS. 2 and 3). In Figs. 2 and 3, the position of the guide groove 6a of the top plate 6 is indicated by a two-dot dotted line. The plurality of seat plates 3 are fixed to the bottom plate 5 by means of an assembly member such as a screw or welding. In addition, the side of the four sides of the bottom plate 5 except the side of the vehicle side is fixed to the side plate 4 having a "C" shape by welding in the other three sides (please refer to FIG. 4 to FIG. 7). . Even the top plate 6 is fixed to the upper side of the side plate 4 by bolts. The top plate 6 forms a part of the upper surface of the platform 100 when the casing 2 is placed in the recess 100a. Further, the top plate 6 is formed with a guide groove 6a extending in parallel with the direction of the platform. The guide groove 6a is an opening that penetrates the top plate 6, and the top plate is formed to be bent downward in the vertical direction in the opening crotch portion (please refer to Figs. 4 and 5). As described above, the box-shaped casing 2 having an opening is formed on the vehicle side. The casing 2 can be embedded in the platform 100 by being disposed in the recess 100a. Then, the horizontal flat pedal 7 is supported by the casing 2 (indicated by two dotted lines in FIGS. 2 and 3) ). The pedal 7 is constructed by: fixing -10- 200817219 on the upper surface of the vehicle-side end portion of the frame 8, and forming a space that can be housed between the bottom plate 5 and the top plate 6 of the casing 2 together with the frame 8. Further, the pedal 7 is disposed such that its upper surface is slightly horizontal with respect to the top plate 6 in accordance with the viewpoint that the passenger getting on and off is easy to walk. The frame 8 is formed by being fixed to each other by a plurality of gusset-shaped members arranged in parallel to the surface of the bottom plate 5 and being welded to each other. Specifically, as shown in Figs. 2 and 3, the frame 8 is composed of the following members: parallel support members 8 1 a to 8 1 e, and the parallel support members 8 1 a to 8 1 e are extended in parallel In the direction in which the pedal 7 advances and retracts toward the vehicle; and the vertical support members 82a to 82f, the vertical support members 82a to 82f extend perpendicular to the parallel support members (parallel to the direction along the platform). In Figs. 2 and 3, the parallel supporting members 8 1 a and 8 1 b located in the left side surface region of the pedal device 1 are supported by the vertical supporting members 82a in the vicinity of the center in the longitudinal direction, and are on the vehicle side. The end on the opposite side is supported by the vertical support member 82b. Similarly, the parallel supporting members 8 1 c and 8 1 d located in the right side region of the pedal device 1 are supported by the vertical supporting members 82e and 82f. Next, the parallel supporting members 81b and 81c are supported by the vertical supporting members 8 2 c in the vicinity of the center in the longitudinal direction. The vertical support member 8 2 c is coupled to the parallel support member 8 1 e, and extends toward the opposite side of the vehicle side in the vicinity of the center in the longitudinal direction. Further, the opposite side end portion of the parallel supporting member 8 U on the vehicle side and the opposite side end portion of the parallel supporting portion 8 1 b on the vehicle side are supported by the vertical supporting member 82d. The bottom plate 5 of the casing 2 is fixed with four sliding rails 8 3 a, 8 3 b, 8 3 c, and 8 3 d extending in parallel with the parallel supporting members -11 - 200817219. The parallel supporting members 81a, 81b, 81c, 81d are respectively supported to slide along the sliding rails corresponding to the sliding rails 83a, 83b, 83c, 83d. Specifically, the sliding rails 8 3 a to 8 3 d are formed with grooves extending in the longitudinal direction on the side surfaces, and the convex portions formed on the side surfaces of the parallel supporting members 8 1 a to 8 1 d can receive the grooves while receiving the grooves. The support moves along one side of the sliding track. Further, guide rollers such as cam followers can be assembled on the side faces of the parallel supporting members 8 1 a to 8 1 d and urged to move along the grooves. As a result, the pedal 7 and the frame 8 can be moved forward and backward from the side of the platform 1 toward the vehicle side by the driving of the motor unit 17 described later. Further, at a position in the casing 2 close to the opposite side end portion of the vehicle side, the locking mechanism for restricting the advancement and retreat movement of the frame 8 is provided to the seat plate 3 twice. The locking mechanism 20 is engaged with the engaging portion 8 a integrally formed on the frame 8 by, for example, electromagnetically performing protrusion and retraction of the snap fastener, and can be restricted: the frame 8 is in the advanced state. Movement in the retracting direction; and movement of the frame 8 in the advancing direction in the retracted state. Further, a seat support 3 is provided on the seat plate 3 of the casing 2, and the top plate support body 9 can support the load acting downward in the vertical direction through the top plate 6. As shown in FIGS. 4 and 5, the top plate support body 9 is disposed at a position closer to the opposite side end of the vehicle 2 in the casing 2, and is disposed such that the length is parallel to the direction in which the pedal 7 advances and retreats. direction. The top plate support body 9 is such that both ends are fixed to the seat plate 3 by bolts or the like, and the center portion is supported by the seat plate 3 and abuts against the top plate 6, and is formed to be bent in a "C" shape. Plate member. The vertical support members 8 2 b, -12- 200817219 82d, 82f of the frame 8 are located between the top plate support body 9 and the seat plate 3, and are movable in the advancing and retracting direction. Next, a configuration for advancing and retracting the pedal 7 toward the vehicle side will be described. In the vicinity of the opposite side end portion of the seat panel 3 constituting the casing 2, the motor unit 17 (driving means) is fixed. The motor unit 17 is composed of an electric motor and a speed reducer that decelerates the rotation of the motor shaft and increases the torque. The drive output shaft (drive shaft) is disposed to face in the vertical direction. A pinion gear 18 (driving means) is fixed to the drive output shaft. Further, in the parallel supporting member 8 1 e to which the frame 8 of the pedal 7 is fixed, a rack 1 9 (driving means) is fixed to be meshed with the pinion gear 18, and the pinion gear 18 is caused to rotate by driving the electric motor. The pedal 7 can be moved forward and backward toward the vehicle. In this manner, the driving means constituted by the motor unit 17, the pinion gear 18, the rack gear 19, and the like can cause the pedal 7 to move forward and backward through the frame 8, and is disposed on the opposite side of the vehicle side close to the casing 2. The portion is located in the casing 2 on the opposite side of the guide groove 6a from the vehicle side. In other words, in the case of being disposed in the casing 2, the driving means that requires a large space in the vertical direction is not disposed closer to the vehicle side than the guiding groove 6a (please refer to Figs. 6 and 7). Figure). In this way, the space can be secured in the casing 2 at a position closer to the vehicle side than the guide groove 6a. Further, the electric motor may constitute a motor having a brake that can brake the rotation caused by the external force to the drive output shaft when the drive is stopped. In this way, the pedal 7 can be held in the stop position in the event of power failure or abnormality. Thereby, the pedal 7 can be prevented from accidentally generating the protruding and retracting movements, and the safety of the passenger can be improved. Furthermore, the 'driving means is not limited to the means constituted by the rack and pinion mechanism described above, and the belt may be rotated by the electric motor to drive the belt wound around the pulley to be fixed to the belt. The structure of the frame moves forward and backward. The seat plate 3 constituting the casing 2 is provided with retracted position stoppers 11a and 12a and thrust position stoppers lib and 12b. Further, the seat plate 3 is provided with a retracted position detecting sensor 13a and a propulsion position detecting sensor 13b. As the above-mentioned sensor, for example, a proximity switch (pr0Ximity switch) can be used, and when the vertical support member 82b approaches a specific position, the rotation of the electric motor can be stopped to stop the movement of the frame 8. The movement of the vertical support members 82b and 8 2f in the advancing and retracting direction is restricted by the retreat position stoppers 1 la and 12a and the propulsion position stoppers 1 lb and 12b, thereby preventing an excessive amount of the propulsion direction and the retracting direction due to an erroneous operation. mobile. For example, when the pedal 7 is moved to the retracting direction, as shown in Fig. 2 and Fig. 5(a), the vertical supporting members 82b and 8 2f abut against the retracted position stop 1 1 a, 1 Stop in the state of 2a. Further, when the pedal 7 is moved to the propulsion direction, as shown in FIGS. 3 and 5(b), the vertical support members 82b and 82f abut against the propulsion position stoppers 1 1 b and 1 2 b. Stop in the state. Here, the frame 8 is configured to be close to the bottom plate 5 of the casing 2, and is formed to secure a space above the frame 8 in the casing 2. Further, the length of the pedal 7 moving forward and backward from the guide groove 6a only to the vehicle side extends parallel to the advancing and retracting direction, and the pedal 7 does not move in the manner of traversing the lower portion of the guiding groove 6a. Therefore, based on the viewpoint that the passenger getting on and off is easy to walk, by moving the forward and backward movement of the pedal 7 whose upper surface position is slightly horizontal to the position of the top plate 6, the space under the guide groove 6a will not be reduced, and it can be easily ensured. The space below the guiding groove 6a. As shown in Fig. 4 and Fig. 5, in the present embodiment, a portion of the door sliding mechanism of the dock door device 200 installed in the platform 100 can be accommodated by the space in the vicinity of the lower side of the guide groove 6a. It refers to anti-vibration fittings 02. The vibration-proof fitting 202 is fixed to the lower end of the door 201, and is disposed in the casing 2 by the guide groove 6a. Then, with the opening and closing of the door 20 1 , for example, in a manner of extending the guide groove 6 a in the casing 2 so as to extend along the rail (not shown in the drawing) provided in the casing 2 . . Thereby, the vibration of the door 20 1 can be prevented. As a result, the pedal device 1 of the present embodiment can be used on the platform 100 together with the dock door device 200 requiring a groove. Next, since the portion of the door sliding mechanism of the dock door device 200 can be accommodated in the casing 2 of the pedal device 1, the spatial restriction in the design of the platform door device 200 can be reduced. In this way, the pedal device 1 can be used to prevent the passenger from falling between the platform 10 and the parked vehicle, and can be improved by the function of the platform door device 200 that can be used simultaneously with the pedal device 1. Device. As described above, it is not limited to the case where the door preventing fastener is provided. For example, the driving belt of the door of the dock door device or the like may be provided in the space inside the pedal device. In addition, the top plate support body 9 is disposed such that the casing 2 is located on the opposite side of the vehicle side from the guide groove 6 a, except that the strength of the casing 2 can be maintained as: -15- 200817219 The passenger getting on and off is on the top plate 6 In the passage, the casing 2 is also not damaged, and the space in the vicinity of the vehicle side in the casing 2 can be made wider. Further, the vehicle side end portion of the frame 8 is formed by the parallel supporting members 8 1 a to 8 1 d which protrude from the vehicle side. That is, the vehicle-side end portions of the parallel supporting members 8 1 a to 8 1 d of the frame 8 are not supported by the vertical supporting members. Therefore, at the vehicle-side end portion of the frame 8, in the direction of the direction perpendicular to the advancing and retracting direction of the pedal 7, that is, the external force parallel to the direction of the upper surface of the pedal 7 (that is, the entering direction of the vehicle) In the case, the frame 8 is formed to be more easily deformed. Thereby, even in the propulsion state of the pedal 7, even if the vehicle collides with the pedal 7, the frame 8 can be deformed or broken, and the frame portion can absorb the punch, thereby suppressing the electric motor of the vehicle or the pedal device 1. Damage to the driving means. Further, in the cross section shown in Fig. 4(a), the vertical support member 82c which supports the position at which the parallel support member is closest to the vehicle side end portion is formed to approach the top plate support body 9 in the retracted state of the pedal 7. Further, in the cross section shown in Fig. 5(a), the vertical support member 8 2 a supporting the position of the parallel support member closest to the vehicle side end portion is formed to be close to the top plate support body 9 in the retracted state of the pedal 7 . Similarly, even the vertical support member 82e located on the right side of the frame 8 in Fig. 2 is disposed close to the top plate support body 9. In this way, since the vertical support member located further on the vehicle side than the top plate support body 9 is disposed so as to approach the top plate support body 9 in a state where the pedal 7 is retracted into the casing 2, the parallel support members are supported by the vertical support members. The position can be closer to the opposite side of the vehicle side. At this time, the frame 8 is formed: -16- 200817219 The frame shape of the cantilever state in which the support position is closer to the opposite side of the vehicle side. Therefore, in the case where an external force toward the entering direction of the vehicle is applied to the vehicle side end portion of the frame 8, the frame 8 becomes more easily deformed. As a result, the effect of absorbing the absorption of the frame portion can be greatly increased, and even in the case where the vehicle collides with the pedal 7, the damage of the vehicle or the like can be suppressed. In this case, since the top plate support body 9 does not interfere with the advancement and retreat movement of the frame 8, and the top plate 6 can be supported at a position closer to the vehicle side end portion, it acts on the upper and lower passengers when walking on the top plate 6. The load can further increase the strength of the pedal device 1. Further, the pedal 7 may be a honeycomb structure such as that formed of aluminum. In this case, the flushing absorbency of the pedal 7 can be improved. As a result, in the case where the vehicle is in contact with the pedal 7, the entire pedal device 1 can be prevented from being damaged. Further, it is also possible to maintain a specific rigidity and a light weight, and the frame 8 supporting the pedal 7 is formed into a lighter and thinner shape. The present invention has been described with reference to the embodiments of the present invention. However, the present invention is not limited to the embodiments described above, and various modifications may be made without departing from the scope of the invention.
