Description

전동차의 안전 발판{SAFETY FOOTING OF STREETCAR}SAFETY FOOTING OF STREETCAR}

본 고안은 전동차의 도어에 설치되는 발판에 관한 것으로, 특히 차량이 정차했을 때 차체와 플랫폼 사이에 개문과 동시에 안전발판이 안착되어 지고, 폐문시에 완전하게 닫히기 직전에 안전 발판이 내접되도록 하여 노약자나 장애자가 안전하게 승하차 하도록 함으로써 승객의 안전사고를 방지할 수 있도록 된 전동차의 안전발판에 관한 것이다.The present invention relates to a footrest installed on a door of an electric vehicle, and in particular, when the vehicle is stopped, the safety footrest is seated at the same time as the door is opened between the vehicle body and the platform, and the safety footrest is inscribed immediately before closing completely when the vehicle is closed. B) It relates to a safety platform for an electric vehicle that enables a person with a disability to safely get on and off to prevent a passenger accident.

일반적으로 지하철의 역사는 직선으로 건설하여 플랫폼과 차량과의 거리인 연단간격을 일정하고 안전하게 유지시켜주는 것이 원칙이라 하지만 지하철이 도심지의 인구집중지역의 기존 대로를 따라 노선이 결정되어 공사가 이루어지므로 도시가스 배관, 도로주변의 고층대형건물, 기존도로의 형상, 지하수와 같은 조건에 따라 역사를 곡선을 주어 건설하였다.In general, the history of the subway is built in a straight line to keep the distance between the platform and the vehicle constant and safe. However, since the subway lines are determined according to the existing streets of the city's population center, construction is carried out. It is constructed by giving a history curve according to the conditions such as city gas piping, high-rise large buildings around the road, the shape of existing roads, and groundwater.

이와 같이 곡선으로 형성된 역사에 도시철도 차량이 정차할 때에는 플랫폼과 차량간의 연단간격이 발생되어 짧은 정차시간에 많은 사람이 이동하면서 사고가 발생하는 경우가 많았으며, 전동차가 정차하게 되는 플랫폼은 전동차의 폭보다 다소 크게 설계되어 전동차와의 간섭이 방지되도록 되어 있는 바, 이 같이 플랫폼과 전 동차 사이의 간격으로 인해 출퇴근시간과 같이 혼잡시간에는 승객의 발이 빠지거나 걸려지게 되어 종종 안전사고가 발생되게 되고, 노약자나 장애인 및 어린이의 경우에는 이러한 위험이 더욱 커지게 되었다.When the urban railway vehicle stops in the curved history, a platform gap between the platform and the vehicle is generated, and many people move in a short stopping time, and accidents occur in many cases. It is designed to be slightly larger than the width to prevent interference with the train.In this way, the passenger's foot falls out or hangs during rush hour, such as commute time, due to the gap between the platform and the train, which often causes safety accidents. This risk is even greater for the elderly, the elderly, the disabled and children.

또한 지하나 지상을 통과하는 전동차로서 플랫폼이 일정하게 되어 있지 않아 높낮이가 상이하여 승하차 승객의 안전성에 문제가 제기되고 있다.In addition, since the platform is not constant as a train passing through the basement or the ground, the height is different, which raises the issue of safety of passengers getting on and off.

상기와 같은 목적을 달성하기 위한 본 고안은, 출입구(도어)를 지지하는 좌우측 지지프레임 하부 내측에 상기 지지프레임에 피스톤이 요홈을 형성하고 고정쇠가 내측에 형성되어 수직방향으로 설치된 실린더와 연결된 핀을 매개로 도어에 돌출편이 부착되어 구동레버의 한쪽 선단이 관절이음으로 연결되며, 다른쪽 선단은 핀을 매개로 발판과 연결되되, 이 발판은 몸체의 길이방향을 따라 3단으로 형성되며 한쪽선단이 상기 지지프레임의 하단부에 힌지 결합으로 연결되어, 상기 실린더를 매개로 실린더 로드가 구동레버를 눌러주므로 힌지를 중심으로 발판을 사용위치 또는 접쳐진 위치로 축선회시키도록 구성되며, 사용위치에서 전동차와 플랫폼 위에 놓여 짐으로써 승객이 승하차 시 안전사고를 방지하고, 문틈에 발이나 가방을 끼워넣고 발차를 지연시키는 폐단을 예방할 수 있도록 하였다.The present invention for achieving the above object, a piston is formed in the support frame in the lower left and right support frame to support the door (door) and the pin is connected to the cylinder installed in the vertical direction formed in the fixing bolt inside The protruding piece is attached to the door, and one end of the drive lever is connected with a joint joint, and the other end is connected with the foot plate via a pin, which is formed in three steps along the length of the body. It is connected to the lower end of the support frame by a hinge coupling, the cylinder rod presses the drive lever via the cylinder, and is configured to pivot the footrest to the use position or the folded position around the hinge, and the electric vehicle in the use position It is placed on the platform to prevent accidents when passengers get on and off. Which was to help prevent the evils.

본 발명의 안전 발판은 전동차의 출입문(도어) 하단에 경사면을 형성하여 고착된 돌출편과; 피스톤에 요홈를 형성하고 고정쇠을 설치하며 외측에 가이드홈을 형성한 실린더와; 발판을 3단으로 형성하고 복원스프링이 내장된 경첩에 체결하여 하단부에 복원스프링을 체결하여 구동레버를 용융시켜 형성한 힌지로 구성되어 있다. The safety footrest of the present invention includes a projecting piece fixed by forming an inclined surface at the bottom of the door (door) of the electric vehicle; A cylinder which forms a groove in the piston, installs a fixing bolt, and forms a guide groove on the outside thereof; It consists of a hinge formed by melting the drive lever by forming a three-stage scaffold and fastening the restoring spring to the lower end by fastening it to a hinge having a restoring spring.

이상에서 설명한 바와 같이 본 고안 전동차의 발판에 따르면, 전동차가 플랫 폼에 정차했을 때 도어가 개방되기 전에 플랫폼과 전동차 사이에 발판이 놓여 지도록 함으로써, 승객이 승하차 시 안전사고가 발생되는 것을 방지하고, 문틈에 발이나 가방을 끼워넣고 발차를 지연시키는 폐단을 예방할 수 있는 효과가 있다As described above, according to the footrest of the electric vehicle of the present invention, when the electric vehicle stops on the platform, the footrest is placed between the platform and the electric vehicle before the door is opened, thereby preventing a safety accident when the passenger gets on and off, There is an effect that prevents closing of feet or bags and delays

도 1은 본 발명의 사시도이고, 도 2a는 안전발판이 도어에 부착된 상태를 보인 단면도이며, 도 2b는 본 발명의 안전 발판이 플랫폼에 내려진 상태를 보인단면 도 3은 피스톤에 내장된 걸림쇠의 작동 상태를 보인 단면도, 도 4는 본 발명의 사용상태도이다.Figure 1 is a perspective view of the present invention, Figure 2a is a cross-sectional view showing a state that the safety footrest is attached to the door, Figure 2b is a cross-sectional view showing a state that the safety footrest of the present invention is lowered to the platform Figure 3 Sectional view showing an operating state, Figure 4 is a state of use of the present invention.

본 발명의 안전 발판은 전동차(1)의 출입문(도어)(2) 하단에 돌출편(3)을 고착하고, 플랫폼(100)에 정차하여 도어(2)가 열리면 도어(2)에 부착된 돌출편(3)의 경사면(3a)이 실린더(4)내에 요홈(4a)을 타고 지나게 되며 요홈(4a)내 형성된 고정쇠 (5)가 돌출편(3)에 의해 눌리면서 실린더(4)와 피스톤(6)이 해제되면서 돌출편 (3)의 경사면(3a)에 따라 아래로 하강하게 되고 피스톤로드(6a)가 신장되면서 직선상에서 구동레버(7)를 아래쪽으로 밀어주게 되고, 이에 따라 구동레버(7)가 힌지 (8)를 매개로 회전운동을 하면서 동시에 발판(9)이 힌지(8)를 중심으로 축 선회하여 플랫폼(100)과 전동차(1)사이에 얹혀지게 되는 바, 이때 상기 발판(9)은 힌지 (8)에 끼워진 복원 스프링(10)에 의해 항상 복원되려는 성질을 지니고 있으며 부착된 논스립(9a)이 플랫폼(100)에 밀착되게 되므로, 승객이 승하차 시 발판(9)이 요동되는 것을 방지하게 됨과 더불어 플랫폼(100)과의 마찰에 따른 소음을 방지시키게 된다. The safety footrest of the present invention secures the protruding piece 3 to the lower end of the door (door) 2 of the electric vehicle 1, and stops on the platform 100, and the protrusion is attached to the door 2 when the door 2 is opened. The inclined surface 3a of the piece 3 passes through the groove 4a in the cylinder 4 and the clamping portion 5 formed in the groove 4a is pressed by the protruding piece 3 so that the cylinder 4 and the piston 6 ) Is released and descends along the inclined surface 3a of the protruding piece 3, and the piston rod 6a is extended to push the driving lever 7 downward in a straight line, thereby driving the driving lever 7 While the rotary movement through the hinge (8) as the center of the footrest (9) is pivoted around the hinge (8) is placed between the platform 100 and the electric vehicle (1), the footrest (9) Has the property to always be restored by the restoring spring 10 fitted to the hinge 8 and the attached non-slip 9a is brought into close contact with the platform 100, When the passenger gets on and off, the footrest 9 is prevented from shaking and the noise caused by friction with the platform 100 is prevented.

또한 상기 발판(9)이 3단으로 되어 있고 단마다 경첩(11)으로 고정되어 있으며 경첩(11) 사이에 복원스프링(12)이 설치되어 있다. In addition, the footrest (9) has three stages and is fixed with hinges (11) for each stage, and restoring springs (12) are provided between the hinges (11).

사용위치로 펼쳐질 때에는 원 방향으로 회전운동을 하게 되므로 플랫폼 (100)의 높이가 다른 역(驛)인 경우에도 무리 없이 사용할 수 있게 된다. When it is unfolded to the use position is to rotate in the circular direction so that even if the height of the platform (100) is inverse (驛) can be used without difficulty.

또한 승객의 승하차가 완료되어 도어(2)가 닫혀지면 복원 스프링(10)의 복원력에 따라 상기한 경우와 반대로 동작되면서 발판(9)을 보관위치로 접어주게 되는 바, 즉 돌출편(3)이 뒤로 이동하면서 실린더 내 요홈(4a)에서 빠지면서 힌지(8)에 체결된 복원 스프링(13)에 의해 발판(9)이 들리게 되고 피스톤로드(6a)가 윗쪽으로 이동되면서 구동레버(7)가 복원스프링(10)에 의해 발판(9)이 힌지(8)를 중심으로 축선회되어 각각 도시된 것과 같이 보관상태로 접혀지게 되는 것이다, In addition, when the passenger's getting on and off is completed and the door 2 is closed, the footrest 9 is folded into the storage position while operating in the opposite direction according to the restoring force of the restoring spring 10, that is, the protruding piece 3 Moving back, the footrest 9 is lifted by the restoring spring 13 fastened to the hinge 8 while being removed from the groove 4a in the cylinder, and the driving lever 7 is restored as the piston rod 6a is moved upward. The footrest 9 is pivoted about the hinge 8 by 10 to be folded in a storage state as shown in the figure, respectively.
