  1 to 3, two movable doors 3 whose back and forth directions are opposite to each other are provided from the left and right end surfaces of the door pocket 2 installed on the track-side end floor surface of the platform 1 so as to freely advance and retreat. Although the door pocket 2 is covered with a cover and the internal structure or the like is not normally visible, FIG. 1 shows the internal structure with respect to the movable door 3 on the left side of the door pocket 2. The internal structure is the same, but the illustration is omitted because the drawing becomes complicated. The dimension of the movable door 3 in the advancing / retreating direction is formed larger than the dimension between the left and right end faces of the door pocket 2, and when the door tip of the movable door 3 is stored up to one end face of the door pocket 2, the door bottom side of the movable door 3 is It protrudes from the end surface on the opposite side of the door pocket 2. For this reason, the opening part for making the door end side of the movable door 3 project is provided in the end surface on the opposite side of the door pocket 2. A door cover 4 formed in a lateral box shape for covering the opening and covering the protruding door bottom side of the movable door 3 is provided so as to freely advance and retract. As shown in the side view of FIG. 3, an opening for allowing the movable door 3 to pass through and an opening for allowing the door cover 4 to pass through are provided on both left and right end surfaces of the door pocket 2. The gap between the movable door 3 and the packing 15 is filled.

  Hereinafter, the internal structure of the door pocket 2 will be described. A support 6 for supporting the movable door 3 is erected on the base portion 5 of the door pocket 2, and a guide rail 8 fixed to the movable door 3 moves along a guide 7 attached to the support 6. Thus, the movable door 3 is provided in the door pocket 2 so as to freely advance and retract. FIG. 4 is a partial side view showing the mounting state of the movable door 3. A drive unit 9 shown in FIG. 5 is provided below the movable door 3 in the door pocket 2. The driving unit 9 has a timing belt 17 hung on a driving pulley 16 that is rotationally driven by a driving motor (not shown), and both ends of the timing belt 17 in the length direction are grooves provided on the lower surface of the movable door 3. It is fixed at both ends in the forward and backward direction. Two rollers 18 are provided on both sides of the drive pulley 16, and the timing belt 17 is pushed into the groove on the lower surface of the movable door 3. With this configuration, when the drive pulley 16 rotates, the movable door 3 moves in the forward / backward direction. Although FIG. 5 illustrates the case where the drive unit 9 is attached to the base unit 5, the drive unit 9 may be attached to the column 6, for example.

  The door cover 4 is supported by a guide roller 10 rotatably attached to the base part 5 so as to be able to advance and retreat, and a spring attachment part 11 provided on the door cover 4 and a spring attachment metal 12 attached to the base part 5. A force is applied to the door cover 4 in a direction to pull it back into the door pocket 2 by a spring 13 attached between the spring cover 13 and the stopper 14 attached to the spring attachment portion 11 of the door cover 4 and the base portion 5. By abutting, the door cover 4 is stopped at a position where it is pulled back to the end surface of the door pocket 2. In this way, the spring mounting portion 11, the spring mounting metal 12, the spring 13 and the stopper 14 provide a retracting means for the door cover 4.

  Next, the operation will be described. When a vehicle (not shown) is not parked on the side of the platform 1, the movable door 3 is closed as shown in FIGS. When the vehicle stops on the side of the platform 1, electric power from a drive control device (not shown) is applied to the drive motor, whereby the rotation shaft of the drive motor rotates and the drive pulley 16 of the drive unit 9 rotates. When the driving pulley 16 rotates, the timing belt 17 hung on the driving pulley 16 moves. Therefore, the movable door 3 whose both ends in the length direction of the timing belt 17 are fixed to both ends in the advancing and retreating direction of the groove on the lower surface is the door pocket. 2 moves in the retracting direction stored in the housing 2. When the movable door 3 moves in the retracting direction, the door bottom side of the movable door 3 comes into contact with the inner side surface of the door cover 4. At this time, since the dimension of the movable door 3 in the advancing / retreating direction is larger than the dimension between the left and right end surfaces of the door pocket 2, the door tip of the movable door 3 is still protruding from the door pocket 2.

  Here, assuming that the position of the vehicle door of the stopped vehicle is the position of the left end face of the door pocket 2 as shown in FIG. 7, the drive control unit moves the movable door 3 on the right side of the door pocket 2. 9 is stopped, and the drive unit 9 that moves the movable door 3 on the left side of the door pocket 2 is moved until the door tip of the movable door 3 reaches the position of the left end surface of the door pocket 2 and then stopped. For this reason, the door cover 4 with which the door bottom end of the left movable door 3 abuts is pushed by the movement of the movable door 3 and the spring 13 of the retracting means is extended to protrude from the right end surface of the door pocket 2. Since the door cover 4 is given a force to be pulled back into the door pocket 2 by the pulling means, the door cover 4 does not protrude from the door pocket 2 larger than the length pushed by the movable door 3. This state is the state shown in FIGS. On the other hand, if the position of the vehicle door of the stopped vehicle is the position of the right end face of the door pocket 2 as shown in FIG. 9, the drive control device moves the movable door 3 on the left side of the door pocket 2. The drive unit 9 that moves the movable door 3 on the right side of the door pocket 2 moves until the door tip of the movable door 3 reaches the right end face position of the door pocket 2 and then stops. For this reason, the door cover 4 with which the door bottom end of the right movable door 3 is in contact protrudes from the left end surface of the door pocket 2 by being pushed by the movement of the movable door 3 and the spring 13 of the retracting means extending. This state is the state shown in FIGS. In this way, the drive control device moves the movable door 3 in accordance with the position of the vehicle door of the stopped vehicle, and opens the movable door 3 to secure a passage for passengers to and from the vehicle.

  In general, the position of the vehicle door of the stopped vehicle differs depending on the type of the vehicle or the like, but the interval between adjacent vehicle doors may also be different. If the smallest closing length of the adjacent vehicle doors is the minimum closing length, the total length of the movable door 3 in the advancing / retreating direction and the plate thickness of the side surface of the door cover 4 is the minimum closing length. Since the home fence device of the present invention is manufactured so as to be less than or equal to this, it can be applied to any vehicle, and the vehicle door position described in FIGS. It describes a vehicle with a closed length. For this reason, when the vehicle where the space | interval of adjacent vehicle doors is larger than minimum closing length stops, when the door front end of one movable door 3 is moved to the end surface of the door pocket 2, the other movable door 3 is the above-mentioned. Even if it is not moved until the door butt side contacts the door cover 4 as described, the passage of the passenger can be secured by moving the door tip according to the position of the vehicle door.

  It is necessary to close the movable door 3 before the vehicle departs. In this case, the drive motor 9 is driven by the rotation of the rotation shaft of the drive motor by the power supplied from the drive control device to the drive motor. The pulley 16 rotates in the direction opposite to that when the door is opened. When the driving pulley 16 rotates in the opposite direction, the timing belt 17 hung on the driving pulley 16 moves, so that both ends in the length direction of the timing belt 17 are fixed to both ends in the advancing and retreating direction of the groove on the lower surface. 3 moves in the advancing direction protruding from the left and right end faces of the door pocket 2. The door cover 4 protruding at this time is also pulled back to the end surface of the door pocket 2 by the pulling force of the spring 13 of the pulling means, and the movable door 3 and the door cover 4 are closed in FIG. 1 and FIG. Return to state.

  As described above, in the home fence apparatus according to the present invention, the drive unit 9 only needs to move the movable door 3, and the door cover 4 is simply provided with a retracting means, so that the structure is simple. Moreover, the control in the drive control device is simple because it is only necessary to move the movable door 3 in accordance with the position of the vehicle door of the vehicle as described above, and when the door position of the vehicle stopped by the platform is different. There is an effect that it is possible to obtain a home fence device having a simple configuration with a small dimension between both end faces of the door pocket 2 in the advancing and retreating direction of the movable door 3. Moreover, since the door cover 4 is provided, the openings provided on the left and right end surfaces of the door pocket 2 are closed in order to pass the door bottom side of the movable door 3 when the movable door 3 is closed. , Dust and the like can be prevented from entering the inside of the door pocket 2.
