그리고 이와 전선(11)으로 연결되어 전기적신호를 전달받아 공압을 발생시키는 공압펌프(21)와 공압절환밸브(22)를 구비한 공압실린더(20)는 지하철(100)하측에 설치된다.And a pneumatic cylinder (20) having a pneumatic pump 21 and a pneumatic switching valve 22 is connected to the wire 11 to generate an air pressure by receiving an electrical signal is installed in the subway (100) below.

또한, 상기 공압실린더(20)의 피스톤(25)선단은, 문짝(110)하측에 설치되는 가이드레일(31)에 결합되어 안내되며 양측단이 스프링(32)으로 탄지된 상태의 안전발판(30)을 와이어(27)로 연결설치하여 구성된다.In addition, the tip of the piston 25 of the pneumatic cylinder 20 is guided by being coupled to the guide rail 31 is installed on the lower side of the door 110, the safety footrest 30 in the both ends are supported by the spring (32) ) Is configured by connecting and installing the wire (27).

한편, 본 발명은 상기 공압실린더(20)의 몸체부분과 피스톤(25)로드선단을 안전발판(30)의 스프링(32)보다 탄성복귀력이 강한 또다른 스프링(40)으로 연결설치하여 공압장치가 고장이 났을경우 피스톤(25)을 후퇴시켜 전진했던 안전발판(30)을 스프링(40)의 복귀력에 의해 지하철(100)몸체내로 후퇴되도록 구성한다.On the other hand, the present invention is installed by connecting the body portion of the pneumatic cylinder 20 and the piston 25 rod end with another spring 40 having a stronger elastic return than the spring 32 of the safety footrest 30 pneumatic device When the failure occurs, the piston 25 is retracted and the safety scaffold 30, which is advanced, is configured to be retracted into the subway 100 body by the return force of the spring 40.

이때, 상기 피스톤(25)로드선단에 일측선단이 결합된 스프링(40)의 타측 선단은 피스톤(25)을 후퇴시켜서 안전발판(30)을 지하철(100)몸체내로 후퇴시킬 수있는 곳이면 어느 곳에 설치하여도 무방하다.At this time, the other end of the spring 40, the one end is coupled to the piston 25 rod end is to any place where the safety footrest 30 can be retracted into the subway 100 body by retracting the piston 25. You may install it.

여기서, 상기 안전발판(30)의 선단에는 충격흡수 및 충격소음방지용 탄성고무체를 형성한다.Here, the elastic rubber body for shock absorption and impact noise prevention is formed at the tip of the safety scaffold 30.

상기와 같은 본 발명은 상기한 일 실시예에 의하여 결코 한정되는 것이 아니며, 와이어(27)의 길이나 공압실린더(20)의 크기 그리고 안전발판(30)의 두께 등 그 밖의 각종 장치들은 그 크기나 부피 길이 등을 사용용도에 알맞게 조정하여 사용한다.The present invention as described above is not limited by the above embodiment, the length of the wire 27, the size of the pneumatic cylinder 20 and the thickness of the safety footrest 30 and other various devices such as Adjust the volume length to suit the intended use.

이와 같이 구성된 본 발명의 지하철 안전발판의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the subway safety footrest of the present invention configured as described above are as follows.

먼저 지하철(100)의 문짝(110)이 닫혀있는 상태에는 첨부도면 도3a에 도시된 바와같이 리미트스위치(10)가 온되며 이의 전기적인 신호가 공압절환밸브(22)가 절환됨과 동시에 공압펌프(21)를 정상작동시켜 피스톤(25)을 후퇴시킴으로써 상기 피스톤(25)의 선단에 와이어(27)로 연결된 안전발판(30)을 잡아당기게 된다.First, when the door 110 of the subway 100 is closed, the limit switch 10 is turned on as shown in FIG. 3A, and the electrical signal thereof is switched by the pneumatic switching valve 22 and the pneumatic pump ( By retracting the piston 25 by operating the normal operation 21, the safety scaffold 30 connected to the front end of the piston 25 by the wire 27 is pulled.

이와같이 하면 상기 안전발판(30)은 가이드레일(31)에 안내되면서 후퇴하게 되는데 이때,상기 안전발판(30)의 양측단에 결합된 스프링(32)은 인장된 상태가 된다.In this way, the safety scaffold 30 is guided to the guide rail 31 to retreat. At this time, the spring 32 coupled to both ends of the safety scaffold 30 is in a tensioned state.

이와같은 상태에서 지하철(100)이 플랫홈에 들어와서 멈춘다음 문짝(110)이 열리게 되면 첨부도면 도3b에 도시된 바와같이 리미트스위치(10)가 오프(OFF)되면서 이의 전기적인 신호가 공압절환밸브(22)를 역으로 작동시킴과 동시에 공압펌프(21)를 역으로 작동시켜 피스톤(25)을 전진시킴으로써 상기 피스톤(25)이전진하면서 와이어(27)로 연결된 안전발판(30)을 자유단상태로 놓아 준다.In this state, when the subway 100 enters the platform and stops, and then the door 110 is opened, the limit switch 10 is turned off (OFF) as shown in FIG. (22) is operated in reverse and at the same time by operating the pneumatic pump 21 in reverse to advance the piston 25 by moving the piston 25 forward while the safety footrest 30 connected to the wire (27) in the free end state Let go.

이와같이 하면 안전발판(30)이 인장되어 있던 스프링(32)의 탄성복귀력에 의해 순간적으로 전방으로 토출되면서 문짝(110)과 플랫홈의 승,하차블록(200)사이의 공간(250)을 연결하여 주게 된다.In this way, the safety scaffold 30 is instantaneously discharged by the elastic return force of the spring 32, which is tensioned, and connects the space 250 between the door 110 and the platform lift / discharge block 200. Given.

따라서, 지하철(100)을 이용하는 승객의 발이 자칫 부주의로 공간으로 미끄러지더라도 안전발판(30)을 디디게 되므로 발이 공간으로 깊숙히 빠져 다치지 않도록 방지하여 줌으로써 지하철운행자는 안전운행을 할 수 있으며 승객은 안심하고 지하철(100)을 이용할 수 있게 된다.Therefore, even if the foot of the passenger using the subway 100 inadvertently slips into space, the footrest of the footrest 30 is prevented, so that the subway operator can operate safely by preventing the foot from falling deeply into the space and injuring the passenger. And the subway 100 can be used.

그리고 본 발명은 상기 공압실린더(20)의 몸체부분과 피스톤(25)로드선단을 안전발판(30)의 스프링(32)보다 탄성복귀력이 강한 또다른 스프링(40)으로 연결설치되어 있기 때문에 만약 지하철(100)의 운행중 안전발판(30)이 승,하차블록(200)을 향해 전진된 상태에서 공압이 새거나 하여 공압장치에 이상이 발생하더라도 안전발판(30)의 스프링(32)보다 탄성복귀력이 강한 또다른 스프링(40)의 탄성복원력에 의해 피스톤(25)이 강제 후퇴됨으로써 전진했던 안전발판(30)이 자동으로 지하철(100)몸체내로 후퇴되기 때문에 지하철(100) 운행에는 전혀 문제가 없다.And the present invention is because the body portion of the pneumatic cylinder 20 and the piston 25 rod end is connected to another spring 40 having a stronger elastic return than the spring 32 of the safety footrest 30 Even if the pneumatic leaks in the state where the safety footrest 30 is advanced toward the up and down block 200 during operation of the subway 100, or an abnormality occurs in the pneumatic device, the elastic return force is greater than that of the spring 32 of the safety footrest 30. The piston 25 is forcedly retracted by the elastic restoring force of another strong spring 40 so that the safety scaffold 30, which has been advanced, is automatically retracted into the subway 100 body. .

상기와 같은 본 발명은 지하철의 문짝이 닫히면 안전발판이 지하철몸체내에 몰입되어 있다가 플랫홈에 정차하여 문짝이 열리면 몰입되어 있던 안전발판이 순간적으로 전방으로 토출되어 문짝과 승,하차블록사이의 공간을 연결하여 주어 지하철을 이용하는 승객의 발이 안전발판으로 하여 공간 깊숙히 빠져 다치지 않게 됨으로써, 안전사고의 위험을 미연에 방지하여주는 매우 획기적인 발명이다.In the present invention as described above, when the door of the subway is closed, the safety scaffold is immersed in the subway body, and when the door is opened and the door is opened, the safety scaffold that is immersed is momentarily discharged to the front and the space between the door and the boarding and discharging block It is a very innovative invention that prevents the risk of a safety accident by connecting the passenger's foot using the subway as a safety step so as not to fall deep into the space.
