2. Description of the Related Art A waist-high movable platform fence has been conventionally known. This is a waist-high door that is installed at the edge of the platform of the station, and consists of a movable fence that is installed in front of the train door, and fixed fences that are installed at the connecting part of the train and before and after the train. It This movable platform fence is installed for the purpose of physically completely separating a train and a person and dramatically improving the safety of passengers on the platform. That is, it is possible to prevent accidents of passengers falling from the platform and accidents of contact with a train, and to effectively prevent a rush-on ride.

In order to drive a door of a conventional movable platform fence, for example, a means for driving a ball screw attached to the door with an electric motor to open and close the door is adopted. In addition, when the door is opened and closed, door hit detection and pulling into the door pocket are also detected.

The conventional movable platform fences are installed at the same intervals as the train doors, and the doors of the train and the movable platform fences are opened and closed in conjunction with each other by opening and closing the doors on the train. Therefore, if the movable platform fence is fully closed when the train departs, there is no need for station staff or conductors to monitor the train and platform, so when performing one-man operation, it is a suitable facility from the viewpoint of ensuring user safety. Can be said.

[0005]

Most of the conventional movable platform fences are made for one-man operation, and are installed when a new line is constructed. However, recently, the idea that a movable platform fence is necessary even if it is not a one-man operation has arisen. That is, the passengers do not fall from the platform and do not come into contact with the train even if they do not drive one-man. Even in the barrier-free law, movable platform fences are targeted devices.

However, since the number of lines to be installed on the already operating lines is extremely large, it is not easy to support all stations unless the cost is reduced. In addition, the stop accuracy at train stations is ±
It is about 350 mm, but is usually said to be about ± 500 mm. Therefore, it is necessary to design the door to be wide to some extent and to design the door pocket to be narrower by that amount. Another issue is how to easily install movable platform fences without disturbing train operation.

The present invention has been made in view of such circumstances, and an object thereof is to provide a movable platform fence having a simple structure, low cost, and easy installation work.

[0008]

In order to achieve the above object, the present invention takes the following means. That is, a movable platform fence provided with a door pocket provided at the edge of the platform and having an opening at one end, and a door capable of advancing and retracting in a substantially horizontal direction from the opening of the door pocket to the platform, wherein the door is At least one horizontal axis generally horizontal to the platform; a vertical axis engaging the horizontal axis and generally vertical to the platform;

FIG. 9 is a diagram showing the operating state of the door.
A fixture 93 for fixing the belt 92 is provided above the leaning portion 91 of the door 90. The belt 92 is stretched around a pulley 94 and receives a rotational force from an electric motor (not shown) to rotate. A grip portion 97 that slides on the first rail 96 provided on the door pocket 95 is provided above the holding portion 91. Further, the door bag 95 is provided with a second rail 98, and the horizontal roller 99 provided in the holding portion 91 rotates on the second rail 98. As a result, the door 90 does not shake in the vertical direction toward the paper surface.

Next, the forward / backward movement of the door will be described.
First, in the state where the door 90 is housed in the door pocket 91, when a closing signal is transmitted, a receiving unit (not shown) receives the closing signal, and the pulley 94 is rotated by the rotational force of the electric motor. The belt 92 rotates with the rotation of the pulley 94, and the fixture 93 provided above the leaning portion 91 is pulled rightward in the drawing. The holding portion 91 slides rightward in the drawing while being supported by the grip portion 97 that grips the first rail 96. At the same time, the horizontal roller 99 rotates on the second rail.
As a result, the door 90 advances from the opening 100 of the door pocket 95. When the door 90 is housed in the door pocket 95, the reverse operation is performed.

In this embodiment, an example in which the belt is used to transmit the driving force has been described, but the present invention is not limited to this, and for example, a mechanism using a ball screw or a linear motor may be adopted. Of course it is possible. What kind of mechanism is adopted for driving the door is appropriately selected from the viewpoint of cost reduction.

FIG. 10 (a) is a view showing a plate-like member provided on the door. The plate-shaped body 101 is made of, for example, a transparent material. For example, four gripping members 102 are provided on one end surface of the plate-shaped body 101.
FIG. 10B is a diagram showing a side surface of the gripping member 102. The holding member 102 has a shape in which the tip is narrower than the diameter of the sub pipe. When the plate-shaped body 101 having the gripping member 102 is pressed against the sub-pipe 21 from the platform side, the gripping member 102 swallows the sub-pipe 21 as shown in FIG. 10C. That is, in FIG. 10C, the right side of the plate-shaped body 101 is the platform.
This makes it possible to easily fix the plate member 101 to the door.

By forming the plate-like member 101 with a transparent material, the visibility of the rail side from the platform is improved and the safety can be easily confirmed. Further, since the condition of the movable platform fence on the rail side can be easily grasped, an effect of preventing mischief or the like is also produced. Further, by attaching the plate-shaped body to the door, it becomes possible to more effectively prevent a part of the body of the passenger from being caught. Furthermore, by providing a plate-like member on the door, it becomes easy to provide an advertisement.

Next, a system relating to the movable platform fence of the present invention will be described. This system omits the signal wiring work by opening and closing the door by using a wireless signal for the purpose of reducing the cost of the on-site work. Further, since the conductor or the station staff performs the opening / closing operation of the door, it is not necessary to install a grounding element for detecting a train stop and a control device for controlling a signal as in the conventional case. In addition, conductors or station staff often use wireless microphones to make announcements on the premises, but in order to facilitate door opening and closing operations, a switch that transmits a wireless signal to control the opening and closing of the door is set wirelessly. It is built into the microphone.

FIG. 11 is a diagram showing a system for opening and closing a movable platform fence wirelessly. The wireless microphone 110 includes a microphone unit 111 and a transmission switch 11
2, an open button 113, and a close button 114. For example, when a conductor talks while pressing the talk switch 112, the speaker (not shown) can be used to broadcast on the premises via a relay 115 provided in the station premises. When the conductor checks the safety of passengers while watching a television monitor or the like and presses the open button 113, an open signal is transmitted and is received by all the reception units of the movable platform fences via the relay 115. Receiving the open signal, the movable platform fences are simultaneously opened while being synchronized by a control device (not shown). Further, when the conductor presses the close button 114, a close signal is transmitted and received by the receiving units of all the movable platform fences via the relay device 115, and each movable platform fence receiving the close signal synchronizes with each other. Open at the same time.

Thus, for example, the conductor can open and close the movable platform fence while making an announcement on the premises. Specifically, when there are many passengers in front of a specific door, it is possible to realize a smooth train operation by guiding the location of the vacant door.

As described above, since the opening / closing operation of the door is performed using the radio signal, the signal wiring work can be omitted. In addition, it is not necessary to install a ground element for detecting a train stop and a control device for controlling a signal as in the conventional case. As a result, it is possible to significantly reduce the cost. Compared with the conventional movable platform fence, the required cost can be suppressed to about 1/2 to 2/3. Furthermore, since the conductor or station staff will open and close the door,
Since a switch for transmitting a radio signal for controlling the opening / closing of the door is incorporated in the wireless microphone, the opening / closing operation of the door becomes easy. Therefore, the conductor or the station staff can perform the opening / closing operation of the door while confirming the safety, so that it is possible to ensure the safety of passengers and operate the train smoothly.

FIG. 12 is a diagram showing an image of a platform provided with a movable platform fence according to the present invention. When the train arrives, departs, or passes, the doors of the movable platform fences are closed, so that the train will not be touched and passengers will not fall on the track. This makes it possible to ensure the safety of passengers.

[0038]

As described above, the movable platform fence according to the present invention includes a door pocket provided at the edge of the platform and having an opening at one end, and a substantially horizontal direction from the opening of the door pocket to the platform. A movable platform fence comprising a retractable door, the door being at least one horizontal axis substantially horizontal to the platform, and a vertical axis that engages the horizontal axis and is substantially vertical to the platform. A configuration including a shaft and a supporting unit that supports the horizontal shaft is adopted.

As a result, it is possible to realize a movable platform fence which has a simple structure and is inexpensive. Further, since the door can be made lighter in weight, the required driving force can be reduced. Further, the weight of the door can be reduced, so that the length of the supporting means can be reduced.

The belt 92 is stretched around a pulley 94 and receives a rotational force from an electric motor (not shown) to rotate. A grip portion 97 that slides on the first rail 96 provided on the door pocket 95 is provided above the holding portion 91. Further, the door bag 95 is provided with a second rail 98, and the horizontal roller 99 provided in the holding portion 91 rotates on the second rail 98. As a result, the door 90 does not shake in the vertical direction toward the paper surface.

Next, the forward / backward movement of the door will be described.
First, in the state where the door 90 is housed in the door pocket 91, when a closing signal is transmitted, a receiving unit (not shown) receives the closing signal, and the pulley 94 is rotated by the rotational force of the electric motor. The belt 92 rotates with the rotation of the pulley 94, and the fixture 93 provided above the leaning portion 91 is pulled rightward in the drawing. The holding portion 91 slides rightward in the drawing while being supported by the grip portion 97 that grips the first rail 96. At the same time, the horizontal roller 99 rotates on the second rail.
As a result, the door 90 advances from the opening 100 of the door pocket 95. When the door 90 is housed in the door pocket 95, the reverse operation is performed.

In this embodiment, an example in which the driving force is transmitted using a belt has been shown, but the present invention is not limited to this, and for example, a mechanism using a ball screw or a linear motor may be adopted. Of course it is possible. What kind of mechanism is adopted for driving the door is appropriately selected from the viewpoint of cost reduction.

FIG. 10 (a) is a view showing a plate-like member provided on the door. The plate-shaped body 101 is made of, for example, a transparent material. For example, four gripping members 102 are provided on one end surface of the plate-shaped body 101.
FIG. 10B is a diagram showing a side surface of the gripping member 102. The holding member 102 has a shape in which the tip is narrower than the diameter of the sub pipe. When the plate-shaped body 101 having the gripping member 102 is pressed against the sub-pipe 21 from the platform side, the gripping member 102 swallows the sub-pipe 21 as shown in FIG. 10C. That is, in FIG. 10C, the right side of the plate-shaped body 101 is the platform.

Furthermore, by providing a plate-like member on the door, it becomes easy to provide an advertisement.

Next, a system relating to the movable platform fence of the present invention will be described. This system omits the signal wiring work by opening and closing the door by using a wireless signal for the purpose of reducing the cost of the on-site work. Further, since the conductor or the station staff performs the opening / closing operation of the door, it is not necessary to install a grounding element for detecting a train stop and a control device for controlling a signal as in the conventional case. In addition, conductors or station staff often use wireless microphones to make announcements on the premises, but in order to facilitate door opening and closing operations, a switch that transmits a wireless signal to control the opening and closing of the door is set wirelessly. It is built into the microphone.

FIG. 11 is a diagram showing a system for opening and closing a movable platform fence wirelessly. The wireless microphone 110 includes a microphone unit 111 and a transmission switch 11
2, an open button 113, and a close button 114. For example, when a conductor talks while pressing the talk switch 112, the speaker (not shown) can be used to broadcast on the premises via a relay 115 provided in the station premises. When the conductor checks the safety of passengers while watching a television monitor or the like and presses the open button 113, an open signal is transmitted and is received by all the reception units of the movable platform fences via the relay 115. Receiving the open signal, the movable platform fences are simultaneously opened while being synchronized by a control device (not shown). Further, when the conductor presses the close button 114, a close signal is transmitted and received by the receiving units of all the movable platform fences via the relay device 115, and each movable platform fence receiving the close signal synchronizes with each other. Open at the same time.

As a result, for example, the conductor can open and close the movable platform fence while making an announcement on the premises. Specifically, when there are many passengers in front of a specific door, it is possible to realize a smooth train operation by guiding the location of the vacant door.

In this way, since the door opening / closing operation is performed using the radio signal, the signal wiring work can be omitted. In addition, it is not necessary to install a ground element for detecting a train stop and a control device for controlling a signal as in the conventional case. As a result, it is possible to significantly reduce the cost. Compared with the conventional movable platform fence, the required cost can be suppressed to about 1/2 to 2/3. Furthermore, since the conductor or station staff will open and close the door,
Since a switch for transmitting a radio signal for controlling the opening / closing of the door is incorporated in the wireless microphone, the opening / closing operation of the door becomes easy. Therefore, the conductor or the station staff can perform the opening / closing operation of the door while confirming the safety, so that it is possible to ensure the safety of passengers and operate the train smoothly.

FIG. 12 is a diagram showing an image of a platform provided with a movable platform fence according to the present invention. When the train arrives, departs, or passes, the doors of the movable platform fences are closed, so that the train will not be touched and passengers will not fall on the track. This makes it possible to ensure the safety of passengers.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable platform fence installed at the edge of a platform.

2. Description of the Related Art A waist-high movable platform fence has been conventionally known. This is a waist-high door that is installed at the edge of the platform of the station, and consists of a movable fence that is installed in front of the train door, and fixed fences that are installed at the connecting part of the train and before and after the train. It This movable platform fence is installed for the purpose of physically completely separating a train and a person and dramatically improving the safety of passengers on the platform. That is, it is possible to prevent accidents of passengers falling from the platform and accidents of contact with a train, and to effectively prevent a rush-on ride.

In order to drive a door of a conventional movable platform fence, for example, a means for driving a ball screw attached to the door with an electric motor to open and close the door is adopted. In addition, when the door is opened and closed, door hit detection and pulling into the door pocket are also detected.

The conventional movable platform fences are installed at the same intervals as the train doors, and the doors of the train and the movable platform fences are opened and closed in conjunction with each other by opening and closing the doors on the train. Therefore, if the movable platform fence is fully closed when the train departs, there is no need for station staff or conductors to monitor the train and platform, so when performing one-man operation, it is a suitable facility from the viewpoint of ensuring user safety. Can be said.

[0005]

Most of the conventional movable platform fences are made for one-man operation, and are installed when a new line is constructed. However, recently, the idea that a movable platform fence is necessary even if it is not a one-man operation has arisen. That is, the passengers do not fall from the platform and do not come into contact with the train even if they do not drive one-man. Even in the barrier-free law, movable platform fences are targeted devices.

However, since the number of lines to be installed on the already operating lines is extremely large, it is not easy to support all stations unless the cost is reduced. In addition, the stop accuracy at train stations is ±
It is about 350 mm, but is usually said to be about ± 500 mm. Therefore, it is necessary to design the door to be wide to some extent and to design the door pocket to be narrower by that amount. Another issue is how to easily install movable platform fences without disturbing train operation.

The present invention has been made in view of such circumstances, and an object thereof is to provide a movable platform fence having a simple structure, low cost, and easy installation work.

A grip portion 97 that slides on the first rail 96 provided on the door pocket 95 is provided above the holding portion 91. Further, the door bag 95 is provided with a second rail 98, and the horizontal roller 99 provided in the holding portion 91 rotates on the second rail 98. As a result, the door 90 does not shake in the vertical direction toward the paper surface.

Next, the forward / backward movement of the door will be described.
First, in the state where the door 90 is housed in the door pocket 91, when a closing signal is transmitted, a receiving unit (not shown) receives the closing signal, and the pulley 94 is rotated by the rotational force of the electric motor. The belt 92 rotates with the rotation of the pulley 94, and the fixture 93 provided above the leaning portion 91 is pulled rightward in the drawing. The holding portion 91 slides rightward in the drawing while being supported by the grip portion 97 that grips the first rail 96. At the same time, the horizontal roller 99 rotates on the second rail.
As a result, the door 90 advances from the opening 100 of the door pocket 95. When the door 90 is housed in the door pocket 95, the reverse operation is performed.

In the present embodiment, an example in which the driving force is transmitted using the belt has been shown, but the present invention is not limited to this, and for example, a mechanism using a ball screw or a linear motor may be adopted. Of course it is possible. What kind of mechanism is adopted for driving the door is appropriately selected from the viewpoint of cost reduction.

FIG. 10 (a) is a view showing a plate-like member provided on the door. The plate-shaped body 101 is made of, for example, a transparent material. For example, four gripping members 102 are provided on one end surface of the plate-shaped body 101.
FIG. 10B is a diagram showing a side surface of the gripping member 102. The holding member 102 has a shape in which the tip is narrower than the diameter of the sub pipe. When the plate-shaped body 101 having the gripping member 102 is pressed against the sub-pipe 21 from the platform side, the gripping member 102 swallows the sub-pipe 21 as shown in FIG. 10C. That is, in FIG. 10C, the right side of the plate-shaped body 101 is the platform.
This makes it possible to easily fix the plate member 101 to the door.

By forming the plate-like member 101 with a transparent material, the visibility from the platform to the rail side is improved, and the safety can be easily confirmed. Further, since the condition of the movable platform fence on the rail side can be easily grasped, an effect of preventing mischief or the like is also produced. Further, by attaching the plate-shaped body to the door, it becomes possible to more effectively prevent a part of the body of the passenger from being caught. Furthermore, by providing a plate-like member on the door, it becomes easy to provide an advertisement.

Next, a system relating to the movable platform fence of the present invention will be described. This system omits the signal wiring work by opening and closing the door by using a wireless signal for the purpose of reducing the cost of the on-site work. Further, since the conductor or the station staff performs the opening / closing operation of the door, it is not necessary to install a grounding element for detecting a train stop and a control device for controlling a signal as in the conventional case. In addition, the conductor or station staff often uses a wireless microphone to make an announcement on the premises, but to facilitate the opening and closing operation of the door, a switch that transmits a wireless signal for controlling the opening and closing of the door is set wirelessly. It is built into the microphone.

FIG. 11 is a diagram showing a system for wirelessly opening and closing a movable platform fence. The wireless microphone 110 includes a microphone unit 111 and a transmission switch 11
2, an open button 113, and a close button 114. For example, when a conductor talks while pressing the talk switch 112, the speaker (not shown) can be used to broadcast on the premises via a relay 115 provided in the station premises. When the conductor checks the safety of passengers while watching a television monitor or the like and presses the open button 113, an open signal is transmitted and is received by all the reception units of the movable platform fences via the relay 115. Receiving the open signal, the movable platform fences are simultaneously opened while being synchronized by a control device (not shown). Further, when the conductor pushes the close button 114, a close signal is transmitted and received by the receiving units of all the movable platform fences via the relay device 115, and each movable platform fence receiving the close signal synchronizes with each other. Open at the same time.

This enables the conductor to open and close the movable platform fence while making an announcement on the premises, for example. Specifically, when there are many passengers in front of a specific door, it is possible to realize a smooth train operation by guiding the location of the vacant door.

In this way, since the door opening / closing operation is performed using the radio signal, the signal wiring work can be omitted. In addition, it is not necessary to install a ground element for detecting a train stop and a control device for controlling a signal as in the conventional case. As a result, it is possible to significantly reduce the cost. Compared with the conventional movable platform fence, the required cost can be suppressed to about 1/2 to 2/3. Furthermore, since the conductor or station staff will open and close the door,
Since a switch for transmitting a radio signal for controlling the opening / closing of the door is incorporated in the wireless microphone, the opening / closing operation of the door becomes easy. Therefore, the conductor or the station staff can perform the opening / closing operation of the door while confirming the safety, so that it is possible to ensure the safety of passengers and operate the train smoothly.

FIG. 12 is a diagram showing an image of a platform on which a movable platform fence according to the present invention is installed. When the train arrives, departs, or passes, the doors of the movable platform fences are closed, so that the train will not be touched and passengers will not fall on the track. This makes it possible to ensure the safety of passengers.
