    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Embodiments of the present invention will be explained below with reference to the accompanying drawings FIG. 1 and FIG. 2. [0007]
  • Referring to FIG. 1 and FIG. 2, the [0008] step 1 is installed on the top of the platform 10 and each horizontal end of the step 1 is pivotally connected to an arm 2 by means of a bearing 4. The arm 2 is coupled to a rotary shaft 3 which is pivotally connected to a bracket 5 with bearings 6 on the upper and lower parts of the rotary shaft. In this embodiment, the bracket 5 is fixed to a movable guard fence 8 on the platform 10. One of the rotary shafts 3 is connected to a driving section 9 which rotates the rotary shaft 3 and the arm 2. In this case, an electric motor may be used as the driving source.
  • Further the [0009] step 1 is provided in the gate part of the movable guard fence 8 with a cover 7 over the step 1.
  • In this configuration, when driving [0010] section 9 rotates the rotary shaft 3, the arm 2 rotates horizontally. As the result, the step 1 coupled with the arm 2 slides out from a home position between the cover 7 and the platform 10 which is indicated by a virtual line of FIG. 2 toward a train body 11 which is indicated by a solid line. When the driving section 9 rotates the rotary shaft 3 in the opposite direction, the step 1 is retracted to the above home position.
  • The present invention can provide a step apparatus for a platform to fill a large gap between a train body and the edge of a platform which can be easily installed on an existing platform and minimize the installation work. The present invention can also provide a step apparatus for a platform which minimizes a difference between the top of the platform and a train floor which is usually high above the platform so that even a wheelchair may go in and out a train. [0011]
  • The step apparatus in accordance with the present invention moves the [0012] step 1 from the home position to a preset extended position as the door of a train 11 opens or as the gate of the movable guard fence 8 opens after the train 11 stops. Similarly, the step 1 is retracted from the extended position to the home position as the door of a train 11 closes or as the gate of the movable guard fence 8 closes.
  • Further, the step apparatus is equipped with a detection means [0013] 12 which detects the step 1 in the extended position and makes alarms when the step 1 must be in the home position.
  • Against incapability of the [0014] driving section 9 due to an unexpected failure, a handle 14 is already mounted or will be easily mounted on the rotary shaft 3 to manually move the step 1.
  • Further, a [0015] rubber roller 13 is provided on the outer edge (facing to a train body 11) of the step 1 which buffers the bumping force and retracts the step by the bumping force when a train body hits the rubber roller in the extended position. This minimizes a damage of the step by collision with a train.
  • FIG. 3 shows another embodiment of the present invention in which [0016] arms 2 a and 2 b coupled to both ends of the step 1 have different lengths L1 and L2. In accordance with this embodiment, when the step 1 slides out from a home position which is indicated by a virtual line toward a train body 11 which is indicated by a solid line, the step 1 is skewed in the extended position as shown in FIG. 3 because the links 4 a and 4 b have different quantities of movement. So, even when the edge of the platform 10 is curved and is not parallel to the train body 11, the step 1 in the extended position can be parallel to the train body 11. Therefore, this embodiment can provide a step apparatus for a platform which can minimize the gap between the step 1 and the train body 11.
  • FIG. 4 is yet a further embodiment of the present invention in which the [0017] arms 2 c and 2 d coupled to both ends of the step 1 have different angles θ1 and θ2 relative to the step 1. This embodiment can also attain the same effect as the embodiment of FIG. 3.
  • FIG. 5 is a more particular embodiment of the present invention in which the [0018] step 11 is shaped so that the step 1 in the extended position may be parallel to the train body as shown in FIG. 5. This embodiment can also attain the same effect as the embodiment of FIG. 3.
