Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when there is an opening and closing member for opening and closing between the first door pocket and the second door pocket (for example, an emergency exit), depending on the installation location of the opening and closing member, it may be necessary to increase the thickness of the door pocket (change the door pocket) in order to provide the opening and closing member. In this case, a situation that hinders passage may occur in an emergency (for example, when an emergency such as a train not stopping at the normal position occurs).

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a platform door device capable of providing an opening and closing member without changing the door pocket.

[Modes for carrying out the invention]

[0022] Hereinafter, an embodiment of the platform door device of the present invention will be described with reference to the drawings. In the following description, expressions indicating relative or absolute arrangements such as "parallel," "orthogonal," "center," and "coaxial" will not only mean such arrangements strictly, but will also include states in which the components are relatively displaced with tolerances or angles and distances that allow the same function to be achieved. In the drawings used in the following description, the scale of each component has been appropriately changed in order to make each component recognizable.

[0023] <Platform door system> Platform door devices 1 are installed on the platforms of railway stations. Platform door devices 1 are installed to prevent passengers, objects, etc., from falling from the platform and from coming into contact with trains. Multiple platform door devices 1 are arranged in a row along the longitudinal direction of the platform. The following description shows one of the multiple platform door devices 1 arranged along the longitudinal direction of the platform.

[0024] Figure 1 is a front view of the platform door device 1 of the first embodiment in its normal state (when the opening / closing door and opening / closing member are fully closed). Figure 2 is a plan view of the platform door device 1 of the first embodiment in its normal state (when the opening / closing door and opening / closing member are fully closed). Figure 3 is a front view of the platform door device 1 of the first embodiment in its normal state (when the opening / closing door is fully open and the opening / closing member is fully closed). Figure 4 is a plan view of the platform door device 1 of the first embodiment in its normal state (when the opening / closing door is fully open and the opening / closing member is fully closed). Figure 5 is a front view of the platform door device 1 of the first embodiment in its emergency state (when the opening / closing door is fully closed and the opening / closing member is fully open). Figure 6 is a plan view of the platform door device 1 of the first embodiment in its emergency state (when the opening / closing door is fully closed and the opening / closing member is fully open). Referring to Figures 1 to 6, the platform door device 1 comprises a first door pocket 2 positioned on the platform, a second door pocket 3 positioned at a distance from the first door pocket 2 in the longitudinal direction of the platform, a first opening / closing door 10 which at least a portion can be stored in the first door pocket 2 and is controlled to open and close so as to shield or open the space on the opposite side of the second door pocket 3, a second opening / closing door 20 which at least a portion can be stored in the second door pocket 3 and is controlled to open and close so as to shield or open the space on the opposite side of the first door pocket 2, and an opening / closing member 30 which is configured to slide relative to either the first door pocket 2 or the second door pocket 3 and opens and closes the space between the first door pocket 2 and the second door pocket 3.

[0025] In the following explanation, the X, Y, and Z orthogonal coordinate system will be used as needed. The X direction corresponds to the longitudinal direction of the platform. The Y direction corresponds to the width direction of the platform. The Y direction corresponds to the thickness direction of the door pocket. The Z direction corresponds to the height direction of the platform door device 1, which is perpendicular to the X and Y directions. In the following explanation, the side of the arrow in the diagram will be considered the positive (+) side, and the side opposite the arrow will be considered the negative (-) side. The +Y side corresponds to the platform side, and the -Y side corresponds to the track side. The +Z side corresponds to the upper side in the vertical direction, and the -Z side corresponds to the lower side in the vertical direction. A plan view seen from the side perpendicular to the longitudinal direction of the platform corresponds to a plan view seen from the Z direction. A side view seen from the longitudinal direction of the platform corresponds to a side view seen from the X direction.

[0026] The first door pocket 2 is installed on the platform. In the space -X side of the first door pocket 2, there is an entrance / exit E1, which is the entrance through which passengers normally board and alight the train.

[0027] The first door pocket 2 is capable of accommodating the first opening / closing door 10. The first door pocket 2 is formed in a rectangular shape when viewed from the Y direction. In the example shown in the figure, the first door pocket 2 is formed in a rectangular parallelepiped shape that is longer in the Z direction than in the X direction. The first door pocket 2 is thicker than the first opening / closing door 10 when viewed from the Z direction. Thickness refers to the dimension in the Y direction. The first door pocket 2 is formed in a shape that covers the tail end of the first opening / closing door 10 from both sides in the Y direction and the +Z side. Note that the configuration of the first door pocket 2 (dimensions, shape, installation configuration, etc.) is not limited to the above and can be changed according to the design specifications.

[0028] The second door pocket 3 is located in a different location on the platform from the first door pocket 2. The second door pocket 3 is spaced apart from the first door pocket 2 in the X direction. In the space +X side of the second door pocket 3, there is an entrance / exit E2, which is the entrance through which passengers normally board and alight the train. Between the first door pocket 2 and the second door pocket 3 in the X direction, there is an emergency exit E3 through which passengers pass in an emergency. The emergency exit E3 is not opened except in emergencies (under normal circumstances).

[0029] The second door pocket 3 is capable of accommodating the second opening / closing door 20 and the opening / closing member 30. The second door pocket 3 is formed in a rectangular shape when viewed from the Y direction. The second door pocket 3 has the same height in the Z direction as the first door pocket 2, and is formed in a rectangular parallelepiped shape that is longer in the X direction than the first door pocket 2. In the example shown in the figure, the second door pocket 3 has a thickness greater than the combined thickness of the second opening / closing door 20 and the opening / closing member 30 when viewed from the Z direction. Note that the thickness of the second door pocket 3 is not limited to the above and can be changed according to the design specifications.

[0030] In the example shown in the figure, the second door pocket 3 has the same thickness as the first door pocket 2 when viewed from the Z direction. The second door pocket 3 is installed in the same position as the first door pocket 2 in the Y direction. The second door pocket 3 is formed to cover the tail ends of the second opening / closing door 20 and the opening / closing member 30 from both sides in the Y direction and from the +Z side. Note that the configuration of the second door pocket 3 (dimensions, shape, installation configuration, etc.) is not limited to the above and can be changed according to the design specifications.

[0031] The first opening / closing door 10 is a door that is controlled by the control panel 4 to open or close so as to shield or open the space (entrance / exit E1) on the -X side of the first door pocket 2. The first opening / closing door 10 is supported inside the first door pocket 2 by a linear rail. The first opening / closing door 10 is configured to slide in the X direction relative to the first door pocket 2. The first opening / closing door 10 is configured to reciprocate in the X direction relative to the first door pocket 2.

[0032] The first opening / closing door 10 is formed in a U-shape (inverted U-shape) that opens on the +X side when viewed from the Y direction. The first opening / closing door 10 includes a door-side bar 11 positioned on the door-side, an upper bar 12 connected to the upper side of the door-side bar 11, and a lower bar 13 connected to the lower side of the door-side bar 11.

[0033] The second opening / closing door 20 is a door that is controlled by the control panel 4 to open or close the space (entrance / exit E2) on the +X side of the second door pocket 3. The second opening / closing door 20 is controlled to open and close in the opposite direction to the opening and closing direction of the first opening / closing door 10. The second opening / closing door 20 is supported inside the second door pocket 3 by a linear rail. The second opening / closing door 20 is configured to slide in the X direction relative to the second door pocket 3. The second opening / closing door is configured to move back and forth in the X direction relative to the second door pocket 3.

[0034] The second opening / closing door 20 is formed in a U-shape (like a U-shape) that opens to the -X side when viewed from the Y direction. The second opening / closing door 20 includes a door-edge side bar 21 positioned on the door-edge side, an upper bar 22 connected to the upper side of the door-edge side bar 21, and a lower bar 23 connected to the lower side of the door-edge side bar 21.

[0035] The opening / closing member 30 is an emergency door that is opened and closed manually to shield or open the space between the first door pocket 2 and the second door pocket 3 (emergency exit E3). Alternatively, the opening / closing member 30 may be an emergency door that is opened and closed electrically. The opening / closing member 30 is supported inside the second door pocket 3 by a linear rail. The opening / closing member 30 is configured to slide in the X direction relative to the second door pocket 3. The opening / closing member 30 is configured to reciprocate in the X direction relative to the second door pocket 3.

[0036] For example, an elastic member may be provided at the edge of the opening / closing member 30. This can mitigate the impact when an object in front of the opening / closing member 30 collides with the edge of the opening / closing member 30.

[0037] The opening / closing member 30 is formed in a U-shape (inverted U-shape) that opens the +X side when viewed from the Y direction. The opening / closing member 30 comprises a door-side bar 31 positioned on the door-side, an upper bar 32 connected to the upper side of the door-side bar 31, and a lower bar 33 connected to the lower side of the door-side bar 31. The door-side bar 31, upper bar 32, and lower bar 33 in the opening / closing member 30 may differ from the door-side bar, upper bar, and lower bar in the opening / closing door 10,20 in at least one of the following: material, height, diameter, and thickness.

[0038] When the first opening / closing door 10 is located inside the first door pocket 2 or the second opening / closing door 20 is located inside the second door pocket 3, the opening / closing member 30 overlaps with either the first opening / closing door 10 or the second opening / closing door 20 in the thickness direction of the first door pocket 2 or the second door pocket 3. When viewed from the Z direction, the opening / closing member 30 overlaps with either the first opening / closing door 10 or the second opening / closing door 20. In the example shown in Figure 4, when the opening / closing member 30 is in the fully closed position, when viewed from the Z direction, the opening / closing member 30 overlaps with the trailing edge of the fully open first opening / closing door 10.

[0039] The opening / closing member 30 is provided so as to cover a portion of the trailing edge of at least one of the fully open first opening / closing door 10 and the second opening / closing door 20 when the opening / closing member 30 is in the fully closed position. In the example shown in Figures 3 and 4, the opening / closing member 30 is provided so as to cover the entire trailing edge of the fully open first opening / closing door 10 when the opening / closing member 30 is in the fully closed position.

[0040] The opening / closing member 30 is offset in the Y direction relative to the second opening / closing door 20. In the example shown in the figure, the opening / closing member 30 is positioned -Y side of the second opening / closing door 20 when viewed from the Z direction. When the opening / closing member 30 and the second opening / closing door 20 approach each other in the X direction, they overlap when viewed from the Y direction without interfering with each other (so as not to hinder opening and closing).

[0041] The platform door device 1 further comprises drive devices 40 and 50 for opening and closing the first opening / closing door 10 and the second opening / closing door 20, and a control panel 4 for controlling the drive devices 40 and 50.

[0042] The drive device 40 (hereinafter also referred to as "first drive device 40") that drives the opening and closing of the first opening / closing door 10 comprises a motor 41, a belt 42, and a pulley 43. The motor 41 is housed in the first door pocket 2. The belt 42 is connected to the first opening / closing door 10. When the motor 41 rotates, it is converted into linear motion of the first opening / closing door 10 in the X direction via the pulley 43 and the belt 42. One end of the belt 42 is fixed to the leading end of the first opening / closing door 10. The other end of the belt 42 is fixed to the trailing end of the first opening / closing door 10. When the motor 41 of the first drive device 40 is driven, the first opening / closing door 10 is opened and closed.

[0043] The motor 41 of the first drive unit 40 is positioned between the upper bar 12 and the lower bar 13 of the first opening / closing door 10. When viewed from the Y direction, the motor 41 of the first drive unit 40 has a Z-direction dimension smaller than the Z-direction distance between the upper bar 12 and the lower bar 13 of the first opening / closing door 10.

[0044] The drive device 50 (hereinafter also referred to as "second drive device 50") that drives the opening and closing of the second opening / closing door 20 comprises a motor 51, a belt 52, and a pulley 53. The motor 51 is housed in the second door pocket 3. The belt 52 is connected to the second opening / closing door 20. When the motor 51 rotates, it is converted into linear motion of the second opening / closing door 20 in the X direction via the pulley 53 and the belt 52. One end of the belt 52 is fixed to the leading end of the second opening / closing door 20. The other end of the belt 52 is fixed to the trailing end of the second opening / closing door 20. When the motor 51 of the second drive device 50 is driven, the second opening / closing door 20 is opened and closed.

[0045] The motor 51 of the second drive unit 50 is positioned between the upper bar 22 and the lower bar 23 of the second opening / closing door 20. When viewed from the Y direction, the motor 51 of the second drive unit 50 has a Z-direction dimension smaller than the Z-direction distance between the upper bar 22 and the lower bar 23 of the second opening / closing door 20.

[0046] The control panel 4 controls the first drive unit 40 and the second drive unit 50. The control panel 4 controls each electrical component installed in the platform door device 1. By controlling the first drive unit 40 and the second drive unit 50, the control panel 4 opens and closes the first opening / closing door 10 and the second opening / closing door 20. Specifically, when a train stops at the platform, the control panel 4 controls the operation to open the first opening / closing door 10 and the second opening / closing door 20, and also controls the operation to close the first opening / closing door 10 and the second opening / closing door 20. For example, signals for controlling the opening and closing of the first opening / closing door 10 and the second opening / closing door 20 are output to the control panel 4 from a higher-level control device (not shown) operated by station staff, train crew, or passengers.

[0047] The control panel 4 is installed in either the first door pocket 2 or the second door pocket 3. In the example shown in the figure, the control panel 4 is installed in the second door pocket 3. The control panel 4 is housed in the second door pocket 3. The second opening / closing door 20, which is configured to slide relative to the second door pocket 3 in which the control panel 4 is installed, includes a door-side bar 21, an upper bar 22, and a lower bar 23. The control panel 4 is positioned between the upper bar 22 and the lower bar 23 of the second opening / closing door 20. When viewed from the Y direction, the control panel 4 has a Z dimension smaller than the distance between the upper bar 22 and the lower bar 23 of the second opening / closing door 20 in the Z direction. When viewed from the Z direction, the control panel 4 may be thicker than the second opening / closing door 20.

[0048] The opening / closing member 30, which is configured to slide relative to the second door pocket 3 where the control panel 4 is located, comprises a door-side bar 31, an upper bar 32, and a lower bar 33. The control panel 4 is positioned between the upper bar 32 and the lower bar 33 of the opening / closing member 30. When viewed from the Y direction, the control panel 4 has a Z-direction dimension smaller than the distance between the upper bar 32 and the lower bar 33 of the opening / closing member 30 in the Z direction. When viewed from the Z direction, the control panel 4 may be thicker than the opening / closing member 30.

[0049] In the example shown in the figure, the second opening / closing door 20 and the opening / closing member 30, each configured to slide relative to the second door pocket 3 where the control panel 4 is located, are equipped with a door-edge bar, an upper bar, and a lower bar. The control panel 4 is positioned between the upper bar and the lower bar of the second opening / closing door 20 and the opening / closing member 30, respectively. The control panel 4 may have the same thickness as the combined thickness of the second opening / closing door 20 and the opening / closing member 30 when viewed from the Z direction.

[0050] The upper bar 32 of the opening / closing member 30 can accommodate the upper bar 12 of the first opening / closing door 10. For example, the upper bar 32 of the opening / closing member 30 may have a hollow structure that opens over the entire X direction. For example, the upper bar 32 of the opening / closing member 30 may be formed in a cylindrical shape (e.g., a square pipe shape) that slidably supports the upper bar 12 of the first opening / closing door 10 in the X direction. The lower bar 33 of the opening / closing member 30 can accommodate the lower bar 13 of the first opening / closing door 10. For example, the lower bar 22 of the opening / closing member 30 may have a hollow structure that opens over the entire X direction. For example, the lower bar 33 of the opening / closing member 30 may be formed in a cylindrical shape (e.g., a square pipe shape) that slidably supports the lower bar 13 of the first opening / closing door 10 in the X direction.

[0051] When the opening / closing member 30 is open, the tail end of the opening / closing member 30 is positioned inward from the outer end of either the first door pocket 2 or the second door pocket 3 in the X direction. In the examples of Figures 5 and 6, when the opening / closing member 30 is open, the tail end of the opening / closing member 30 is positioned on the -X side of the +X side end of the second door pocket 3. On the other hand, when the opening / closing member 30 is open, the leading end of the opening / closing member 30 may be positioned on the -X side of the -X side end of the second door pocket 3. The entrance / exit E2 on the second opening / closing door 20 side may be used as an emergency exit.

[0052] The platform door device 1 further includes a notification unit 6 that notifies when the opening / closing member 30 becomes openable. When the opening / closing member 30 becomes openable, for example, it may be when the opening / closing member 30 is fully closed or when the lock on the opening / closing member 30 is released.

[0053] For example, the notification unit 6 has a function to notify when a lock release signal is input or when the fully closed state is detected by the sensor. This allows the conductor or others to be notified of the possibility that the opening / closing member 30 may open.

[0054] For example, the notification unit 6 may notify the opening and closing direction of the opening / closing member 30 when the opening and closing of the opening / closing member 30 is detected by the sensor. This allows passengers exiting the emergency exit E3 when the opening / closing member 30 is open to understand the opening and closing direction of the opening / closing member 30.

[0055] The control panel 4 keeps the first opening / closing door 10 and the second opening / closing door 20 fully closed when the opening / closing member 30 is opened. Examples of how to maintain the doors fully closed include the motors of the drive units 40 and 50 not rotating, the motors rotating in the closing direction so that the first opening / closing door 10 and the second opening / closing door 20 close, and locking the first opening / closing door 10 and the second opening / closing door 20 with an electric lock (not shown).

[0056] Furthermore, when the opening / closing member 30 is opened, both the first opening / closing door 10 and the second opening / closing door 20 may be housed in the opening / closing member 30 while the first opening / closing door 10 and the second opening / closing door 20 are kept fully closed.

[0057] The platform door device 1 may be equipped with an obstacle sensor (not shown) that detects obstacles between the vehicle and the platform door device 1, or at the entrance / exit. Examples of obstacles include umbrellas and bags. For example, the obstacle sensor is a 3D sensor that captures the shape, position, and distance of the obstacle in three dimensions. The obstacle sensor may be installed, for example, near the control panel 4.

[0058] The platform door device 1 may include an opening / closing detection unit (not shown) that detects the opening / closing state of the first opening / closing door 10 and the second opening / closing door 20 and the opening / closing member 30. For example, the opening / closing detection unit may include a fully closed position sensor that detects whether the first opening / closing door 10 and the second opening / closing door 20 and the opening / closing member 30 are in a fully closed position. For example, the opening / closing detection unit may include a fully open position sensor that detects whether the first opening / closing door 10 and the second opening / closing door 20 and the opening / closing member 30 are in a fully open position.

[0059] The platform door device 1 may further include a control panel 5 that controls a drive device for driving the opening and closing member 30 to open and close. Basically, the opening and closing member 30 is opened and closed manually. The drive device (not shown) for driving the opening and closing member 30 to open and close may be configured, for example, in the same way as a drive device for driving an opening and closing door. The drive device for driving the opening and closing member 30 to open and close may be configured, for example, in the same way as a drive device for driving an opening and closing door, by including a motor, pulleys, and a belt.

[0060] The control panel 5, which controls the drive device that opens and closes the opening / closing member 30, is fundamentally different from the control panel 4, which controls the drive device that opens and closes the opening / closing door. However, the control panel 5 that controls the drive device that opens and closes the opening / closing member 30 may be the same as the control panel 4 that controls the drive device that opens and closes the opening / closing door. For example, the opening and closing control for opening and closing the opening / closing member 30 may be performed by the control panel 4.

[0061] In the platform door device 1, the first opening / closing door 10, the second opening / closing door 20, and the opening / closing member 30 open and close at different times. The opening / closing timing refers to the timing at which the first opening / closing door 10, the second opening / closing door 20, and the opening / closing member 30 open and close during normal operation and during emergency operation.

[0062] In the platform door device 1, an opening / closing member 30 is supported in either the first door pocket 2 or the second door pocket 3, and a fixing part 7 for fixing the opening / closing member 30 is further provided on the other. In the example shown in the figure, the opening / closing member 30 is supported in the second door pocket 3. The fixing part 7 is provided in the first door pocket 2. In the example shown in the figure, the fixing part 7 is located on the Z-center side of the +X edge of the first door pocket 2 when viewed from the Y direction.

[0063] For example, the fixing part 7 is a locking device that locks the opening / closing member 30 from moving in the opening direction when the opening / closing member 30 is in the fully closed state. The locking device may be mechanical or electronic. For example, in the case of a mechanical locking device, the lock on the opening / closing member 30 may be released by a manual unlocking operation in an emergency.

[0064] The platform door device 1 may also be equipped with a proximity sensor (not shown) to monitor the locked state of the electric locks for locking the first opening / closing door 10 and the second opening / closing door 20. For example, in an emergency, if the lock on the opening / closing member 30 is released by a manual unlocking operation, it is possible to output an unlocking signal using the proximity sensor or the like so that the first opening / closing door 10 and the second opening / closing door 20 do not operate with an open signal.

[0065] <Normal operation (when the opening / closing doors and opening / closing components are fully closed)> Next, an example of the normal operation of the platform door device 1 (when the opening / closing doors and opening / closing members are fully closed) will be described. In normal operation (except in emergencies), as shown in Figure 1, the first opening / closing door 10, the second opening / closing door 20, and the opening / closing members 30 are fully closed. Specifically, the first opening / closing door 10 blocks the entrance / exit E1 on the -X side of the first door pocket 2, the second opening / closing door 20 blocks the entrance / exit E2 on the +X side of the second door pocket 3, and the opening / closing members 30 blocks the emergency exit E3 between the first door pocket 2 and the second door pocket 3. In the state shown in Figure 1, each entrance / exit E1, E2 and the emergency exit E3 are closed so that people cannot pass through. This prevents people on the platform side from entering the track side.

[0066] <Normal state (when the opening / closing door is fully open and the opening / closing mechanism is fully closed)> Next, an example of the normal operation of the platform door device 1 (when the opening / closing doors are fully open and the opening / closing members are fully closed) will be described. For example, when the motor 41 of the first drive unit 40 is rotated in one direction around its axis from the state shown in Figure 1, the first opening / closing door 10 is moved to the +X side (direction of arrow V1 shown in Figure 1) to open the entrance / exit E1 due to its connection with the belt 42. Similarly, when the motor 51 of the second drive unit 50 is rotated in one direction around its axis, the second opening / closing door 20 is moved to the -X side (direction of arrow V2 shown in Figure 1) to open the entrance / exit E2 due to its connection with the belt 52. As a result, in the state shown in Figure 3, each entrance / exit E1 and E2 is opened so that people can pass through. That is, in the state shown in Figure 3, the first opening / closing door 10 and the second opening / closing door 20 are fully open, and the opening / closing members 30 are fully closed. This allows passengers disembarking from a train arriving at the platform to exit through doorways E1 and E2 and proceed onto the platform.

[0067] When a vehicle departs from the platform, the reverse operation is performed. Specifically, when the motor 41 of the first drive unit 40 is rotated in the opposite direction around its axis from the state shown in Figure 3, the first opening / closing door 10 moves to the -X side (opposite direction to the arrow V1 shown in Figure 3) to shield the entrance / exit E1 due to its connection with the belt 42. Similarly, when the motor 51 of the second drive unit 50 is rotated in the opposite direction around its axis, the second opening / closing door 20 moves to the +X side (opposite direction to the arrow V2 shown in Figure 3) to shield the entrance / exit E2 due to its connection with the belt 52. As a result, when a vehicle departs from the platform, each entrance / exit E1 and E2 is closed to prevent people from passing through (see Figure 1).

[0068] <Emergency situation (when the opening / closing door is fully closed and the opening / closing mechanism is fully open)> Next, an example of an emergency situation for the platform door device 1 (when the opening / closing doors are fully closed and the opening / closing member is fully open) will be described. For example, in an emergency, if the first opening / closing door 10 and the second opening / closing door 20 remain closed and cannot be opened, the lock state of the fixing part 7 (e.g., locking device) that fixes the opening / closing member 30 is released. Then, by manually pushing the unlocked opening / closing member 30 to the +X side (in the direction of arrow V3 shown in Figure 5), the opening / closing member 30 can open the emergency exit E3. In the state shown in Figure 5, the emergency exit E3 is opened so that a person can pass through. That is, in the state shown in Figure 5, the first opening / closing door 10 and the second opening / closing door 20 are fully closed, and the opening / closing member 30 is fully open. This allows passengers to safely and quickly escape through the emergency exit E3 in an emergency.

[0069] <Effects and Effects> As described above, the platform door device 1 according to this embodiment comprises a first door pocket 2 arranged on the platform, a second door pocket 3 arranged at a distance from the first door pocket 2 in the longitudinal direction of the platform, a first opening / closing door 10 in which at least a portion can be stored in the first door pocket 2 and is controlled to open and close so as to shield or open the space on the opposite side of the second door pocket 3, a second opening / closing door 20 in which at least a portion can be stored in the second door pocket 3 and is controlled to open and close so as to shield or open the space on the opposite side of the first door pocket 2, and an opening / closing member 30 configured to be slidable relative to either the first door pocket 2 or the second door pocket 3 and to open and close the space between the first door pocket 2 and the second door pocket 3. When the first opening / closing door 10 is located inside the first door pocket 2 or the second opening / closing door 20 is located inside the second door pocket 3, the opening / closing member 30 overlaps with either the first opening / closing door 10 or the second opening / closing door 20 in the thickness direction of the first door pocket 2 or the second door pocket 3.

[0070] For example, if the opening / closing member 30 does not overlap with the opening / closing doors 10 and 20 in the thickness direction of the door pockets 2 and 3, then it is necessary to increase the thickness of the door pocket (change the door pocket) in order to install the opening / closing member 30. In contrast, with this configuration, the opening / closing member 30 overlaps with the first opening / closing door 10 in the thickness direction of the first door pocket 2, so the opening / closing member 30 can be installed without changing the door pocket.

[0071] The opening / closing member 30 according to this embodiment is provided so as to cover a portion of the door edge of at least one of the fully open first opening / closing door 10 and the second opening / closing door 20 when the opening / closing member 30 is in the fully closed state. This configuration contributes to improved safety compared to the case where a portion of the door edge of the fully open door 10, 20 is exposed from the fully closed opening / closing member 30. In this embodiment, since the opening / closing member 30 is provided to cover the entire door edge of the fully open first door 10 when it is in the fully closed state, it is possible to avoid the door edge of the fully open first door 10 hitting objects on the platform side.

[0072] In this embodiment, at least one of the first opening / closing door 10, the second opening / closing door 20, and the opening / closing member 30 comprises a door-side bar positioned on the door-side, an upper bar connected to the upper side of the door-side bar, and a lower bar connected to the lower side of the door-side bar. This configuration allows for a smaller air-receiving area compared to the case where the opening and closing doors 10, 20 and the opening and closing members 30 are formed in a surface shape.

[0073] In the platform door device 1 according to this embodiment, when the opening / closing member 30 is open, the tail end of the opening / closing member 30 is positioned inward from the outer end of either the first door pocket 2 or the second door pocket 3 in the longitudinal direction of the platform. With this configuration, when the opening / closing member 30 is opened, the tail end of the opening / closing member 30 does not protrude in the opposite direction of the door pocket. Therefore, by opening the door in the portion where the opening / closing member 30 does not protrude, this portion can also be used as an emergency exit.

[0074] The platform door device 1 according to this embodiment further includes a notification unit 6 that notifies when the opening / closing member 30 becomes openable or closable. With this configuration, notification allows for quick confirmation that the opening / closing member 30 has entered an open / closed state.

[0075] The platform door device 1 according to this embodiment further includes a control panel 4 that maintains the first opening / closing door 10 and the second opening / closing door 20 in a fully closed position when the opening / closing member 30 is opened. This configuration makes it possible to prevent objects from falling through the opening and closing doors 10 and 20 when the opening and closing member 30 is opened.

[0076] The platform door device 1 according to this embodiment further includes a control panel 5 that controls a drive device for driving the opening and closing member 30 to open and close. With this configuration, the opening / closing member 30 can be opened and closed electrically.

[0077] In the platform door device 1 according to this embodiment, the first opening / closing door 10, the second opening / closing door 20, and the opening / closing member 30 are opened and closed at different times. This configuration contributes to improved safety.

[0078] In the platform door device 1 according to this embodiment, the opening / closing member 30 is supported in either the first door pocket 2 or the second door pocket 3, and the other is further provided with a fixing part 7 for fixing the opening / closing member 30. This configuration contributes to improved safety.

[0079] <Second Embodiment> The following describes the platform door device 201 according to the second embodiment. In the following description, parts having the same functions as those described in the first embodiment will be given the same names and reference numerals, and their specific descriptions will be omitted.

[0080] Figure 7 is a front view of the platform door device 201 of the second embodiment in its normal state (when the opening / closing door and opening / closing member are fully closed). Figure 8 is a plan view of the platform door device 201 of the second embodiment in its normal state (when the opening / closing door and opening / closing member are fully closed). Figure 9 is a front view of the platform door device 201 of the second embodiment in its normal state (when the opening / closing door is fully open and the opening / closing member is fully closed). Figure 10 is a plan view of the platform door device 201 of the second embodiment in its normal state (when the opening / closing door is fully open and the opening / closing member is fully closed). Figure 11 is a front view of the platform door device 201 of the second embodiment in its emergency state (when the opening / closing door is fully closed and the opening / closing member is fully open). Figure 12 is a plan view of the platform door device 201 of the second embodiment in its emergency state (when the opening / closing door is fully closed and the opening / closing member is fully open). Referring to Figures 7 to 12, the platform door device 201 comprises a first door pocket 2, a second door pocket 3, a first opening / closing door 10, a second opening / closing door 20, and an opening / closing member 230.

[0081] The opening / closing member 230 is an emergency door that is opened and closed manually to shield or open the emergency exit E3 between the first door pocket 2 and the second door pocket 3. Alternatively, the opening / closing member 230 may be an emergency door that is opened and closed electrically. The opening / closing member 230 is supported inside the first door pocket 2 by a linear rail 215. The opening / closing member 230 is configured to slide in the X direction relative to the first door pocket 2. The opening / closing member 230 is configured to reciprocate in the X direction relative to the first door pocket 2.

[0082] For example, an elastic member may be provided at the edge of the opening / closing member 230. This can mitigate the impact when an object in front of the opening / closing member 230 collides with the edge of the opening / closing member 230.

[0083] The opening / closing member 230 is formed in a U-shape (like a U-shape) that opens the -X side when viewed from the Y direction. The opening / closing member 230 comprises a door-side bar 231 positioned on the door-side, an upper bar 232 connected to the upper side of the door-side bar 231, and a lower bar 233 connected to the lower side of the door-side bar 231.

[0084] When the first opening / closing door 10 is located inside the first door pocket 2 or the second opening / closing door 20 is located inside the second door pocket 3, the opening / closing member 230 overlaps with either the first opening / closing door 10 or the second opening / closing door 20 in the thickness direction of the first door pocket 2 or the second door pocket 3. When viewed from the Z direction, the opening / closing member 230 overlaps with either the first opening / closing door 10 or the second opening / closing door 20. In the examples shown in Figures 8, 10, and 12, the opening / closing member 230 overlaps with the first opening / closing door 10 when viewed from the Z direction. In the examples shown in Figures 8 and 10, when the opening / closing member 230 is in the fully closed position, it overlaps with the trailing edge of the fully open first opening / closing door 10 when viewed from the Z direction. In the example shown in Figure 12, when the opening / closing member 230 is in the fully open position, it overlaps with the trailing edge of the fully closed first opening / closing door 10 when viewed from the Z direction.

[0085] The opening / closing member 230 is provided so as to cover a portion of the trailing edge of at least one of the fully open first opening / closing door 10 and the second opening / closing door 20 when the opening / closing member 230 is in the fully closed position. In the example shown in Figures 7 to 10, the opening / closing member 230 is provided so as to cover the entire trailing edge of the fully open first opening / closing door 10 when the opening / closing member 230 is in the fully closed position.

[0086] The opening / closing member 230 further comprises a linear rail 235 for the opening / closing door, which is configured to slide relative to the door pocket in which the opening / closing member 230 is configured to slide, to open and close. In the example shown in the figure, the opening / closing member 230 is configured to slide relative to the first door pocket 2. The linear rail 235 is a rail for the opening / closing door 10, which is configured to slide relative to the first door pocket 2, to open and close. The linear rail 235 is located inside the opening / closing member 230. When viewed from the Y direction, the linear rail 235 extends along the X direction, on the Z-center side, inside each of the upper bar 232 and lower bar 233 of the opening / closing member 230.

[0087] The motor 41 of the first drive unit 40 is positioned between the upper bar 232 and the lower bar 233 of the opening / closing member 230. When viewed from the Y direction, the motor 41 of the first drive unit 40 has a Z-direction dimension smaller than the Z-direction distance between the upper bar 232 and the lower bar 233 of the opening / closing member 230.

[0088] In this embodiment, the opening / closing member 230 is supported in the first door pocket 2. The fixing part 7 is provided in the second door pocket 3. When viewed from the Y direction, the fixing part 7 is located on the Z-center side of the -X edge of the second door pocket 3. For example, the fixing part 7 is a locking device that locks the opening / closing member 230 from moving in the opening direction when the opening / closing member 230 is in the fully closed state. The locking device may be mechanical or electronic. For example, in the case of a mechanical locking device, the lock on the opening / closing member 230 may be released by a manual unlocking operation in an emergency.

[0089] Next, an example of the platform door device 201 in normal operation (when the opening / closing doors and opening / closing members are fully closed) will be described. In normal operation (except in emergencies), as shown in Figure 7, the first opening / closing door 10, the second opening / closing door 20, and the opening / closing members 230 are fully closed. Specifically, the first opening / closing door 10 blocks the entrance / exit E1 on the -X side of the first door pocket 2, the second opening / closing door 20 blocks the entrance / exit E2 on the +X side of the second door pocket 3, and the opening / closing members 230 blocks the emergency exit E3 between the first door pocket 2 and the second door pocket 3. In the state shown in Figure 7, each entrance / exit E1, E2 and the emergency exit E3 are closed so that people cannot pass through. This prevents people on the platform side from entering the track side.

[0090] Next, an example of the normal operation of the platform door device 201 (when the opening / closing doors are fully open and the opening / closing members are fully closed) will be described. For example, when the motor 41 of the first drive unit 40 is rotated in one direction around its axis from the state shown in Figure 7, the first opening / closing door 10 is moved to the +X side (direction of arrow V1 shown in Figure 7) to open the entrance / exit E1 due to its connection with the belt 42. At this time, in the second embodiment, the first opening / closing door 10 is moved to the +X side along the linear rail 235 arranged inside the opening / closing member 230. Similarly, when the motor 51 of the second drive unit 50 is rotated in one direction around its axis, the second opening / closing door 20 is moved to the -X side (direction of arrow V2 shown in Figure 7) to open the entrance / exit E2 due to its connection with the belt 52. As a result, in the state shown in Figure 9, each entrance / exit E1 and E2 is opened so that people can pass through. In other words, in the state shown in Figure 9, the first opening / closing door 10 and the second opening / closing door 20 are fully open, and the opening / closing member 230 is fully closed. This allows passengers disembarking from a train arriving at the platform to exit through the entrances E1 and E2 and proceed to the platform.

[0091] When a vehicle departs from the platform, the reverse operation is performed. Specifically, when the motor 41 of the first drive unit 40 is rotated in the other direction around its axis from the state shown in Figure 9, the first opening / closing door 10 moves to the -X side (opposite direction to the arrow V1 direction shown in Figure 9) to shield the entrance / exit E1 due to its connection with the belt 42. In this second embodiment, the first opening / closing door 10 moves to the -X side along the linear rail 235 arranged inside the opening / closing member 230. Similarly, when the motor 51 of the second drive unit 50 is rotated in the other direction around its axis, the second opening / closing door 20 moves to the +X side (opposite direction to the arrow V2 direction shown in Figure 9) to shield the entrance / exit E2 due to its connection with the belt 52. As a result, when a vehicle departs from the platform, each entrance / exit E1, E2 is shielded so that people cannot pass through.

[0092] Next, an example of an emergency situation for the platform door device 201 (when the opening / closing doors are fully closed and the opening / closing member is fully open) will be described. For example, in an emergency, if the first opening / closing door 10 and the second opening / closing door 20 remain closed and cannot be opened, the lock state of the fixing part 7 (e.g., a locking device) that fixes the opening / closing member 230 is released. Then, by manually pushing the unlocked opening / closing member 230 to the -X side (in the direction of arrow V4 shown in Figure 11), the opening / closing member 230 can open the emergency exit E3. In the state shown in Figure 11, the emergency exit E3 is opened so that a person can pass through. That is, in the state shown in Figure 11, the first opening / closing door 10 and the second opening / closing door 20 are fully closed, and the opening / closing member 230 is fully open. This allows passengers to safely and quickly escape through the emergency exit E3 in an emergency.

[0093] As described above, the opening / closing member 230 according to this embodiment further comprises a linear rail 235 for the opening and closing movement of the first opening / closing door 10, which is configured to be slidable relative to the first door pocket 2, the opening / closing member 230. The linear rail 235 is located inside the opening / closing member 230. This configuration allows for securing storage space within the door pocket without altering the first door pocket 10.

[0094] <Variation> It should be noted that the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0095] In the embodiments described above, the opening / closing member was described as being provided in such a way that when the opening / closing member is in the fully closed state, it covers a portion of the trailing edge of at least one of the fully open first and second opening / closing doors. However, the invention is not limited to this. For example, the opening / closing member may be provided in such a way that when the opening / closing member is in the fully closed state, it exposes a portion of the trailing edge of each of the fully open first and second opening / closing doors. The manner in which the fully closed opening / closing member covers a portion of the trailing edge of the fully open opening / closing door can be changed according to the design specifications.

[0096] In the above-described embodiments, an example has been described in which at least one of the first opening / closing door, the second opening / closing door, and the opening / closing member includes a door-end side bar disposed on the door-end side, an upper bar connected to the upper side of the door-end side bar, and a lower bar connected to the lower side of the door-end side bar, but the present invention is not limited thereto. For example, each of the opening / closing door and the opening / closing member may be formed in a planar shape. The configurations of the opening / closing door and the opening / closing member can be changed according to the design specifications.

[0097] In the above-described embodiments, the platform door device further includes a control panel that controls a driving device for driving at least one of the first opening / closing door and the second opening / closing door to open and close. The control panel is provided in either the first door pocket or the second door pocket. The opening / closing door configured to be slidable with respect to the door pocket provided with the control panel includes a door-end side bar, an upper bar, and a lower bar. The control panel has been described by way of example as being disposed between the upper bar and the lower bar, or having a greater thickness than the opening / closing door in plan view, but the present invention is not limited thereto.

[0098] For example, the control panel may be disposed between the upper bar and the lower bar of the opening / closing door configured to be slidable with respect to the door pocket provided with the control panel, or may have a smaller thickness than the opening / closing door in a side view seen from the longitudinal direction of the platform. As shown in FIG. 13, the control panel 4 is disposed between the upper bar 22 and the lower bar 23 of the second opening / closing door 20 configured to be slidable with respect to the second door pocket 3 provided with the control panel 4, and may have a smaller thickness than the second opening / closing door 20 when viewed from the X direction. When viewed from the X direction, the maximum thickness T1 in the Y direction of the control panel 4 may be smaller than the maximum thickness T2 in the Y direction of the second opening / closing door 20 (T1 < T2). According to this configuration, the control panel 4 can be provided without changing the second door pocket 3.

[0099] For example, the control panel may be disposed between the upper bar and the lower bar of an opening / closing member configured to be slidable with respect to a pocket provided with the control panel, or may have a thickness smaller than that of the opening / closing member in a side view seen from the longitudinal direction of the platform. As shown in FIG. 14, the control panel 4 is disposed between the upper bar 32 and the lower bar 33 of an opening / closing member 30 configured to be slidable with respect to a second pocket 3 provided with the control panel 4, and may have a thickness smaller than that of the opening / closing member 30 when viewed in the X direction. When viewed in the X direction, the maximum thickness T1 in the Y direction of the control panel 4 may be smaller than the maximum thickness T3 in the Y direction of the opening / closing member 30 (T1 < T3). According to this configuration, the control panel 4 can be provided without changing the second pocket 3.

[0100] For example, the control panel may be disposed between the upper bar and the lower bar of each of an opening / closing door and an opening / closing member configured to be slidable with respect to a pocket provided with the control panel, or may have a thickness smaller than that of each of the opening / closing door and the opening / closing member in a side view seen from the longitudinal direction of the platform. As shown in FIG. 15, the control panel 4 is disposed between the upper bars 22, 32 and the lower bars 23, 33 of a second opening / closing door 20 and an opening / closing member 30 configured to be slidable with respect to a second pocket 3 provided with the control panel 4, and may have a thickness smaller than that of each of the second opening / closing door 20 and the opening / closing member 30 when viewed in the X direction. When viewed in the X direction, the maximum thickness T1 in the Y direction of the control panel 4 may be smaller than the maximum thickness T2 in the Y direction of the second opening / closing door 20 and the maximum thickness T3 in the Y direction of the opening / closing member 30 (T1 < T2, T1 < T3). According to this configuration, the control panel 4 can be provided without changing the second pocket 3.

[0101] For example, the second opening / closing door 20 may be housed in the opening / closing member 30.
