Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a platform screen door provided on a platform of a station such as a railway for the purpose of securing passengers' safety, in particular, a train of a different vehicle type is stopped, and an entrance / exit is provided for each train. The platform screen door which is effective when is not constant.

[0002]

2. Description of the Related Art Conventional platform screen doors suitable for a case where the entrance is not constant for each train are described in JP-A-5-32164 and JP-A-5-32165. The former discloses, in particular, a door opening / closing drive device, and the latter details a sliding door device of a landing that is opened / closed by the drive device. The door opening / closing drive device shown by the former etc. is, as shown in FIG.
B. Drive rollers 55A and 55B rotating at an intersection angle are brought into contact with driven rollers 53A and 53B provided on a plurality of sliding doors (doors) 51 suspended from
Any of the sliding doors 51 is opened and closed by the movement of the sliding doors 3A and 53B.
They are arranged at intervals shorter than the length of 53B.

[0003] As for the sliding door device of the landing, the latter publication and the like have a configuration as shown in FIG. 8. That is, the track vehicles 61A, 6 connected by the coupler 63
At the platform 2 where the vehicle 1B stops, a plurality of sliding doors 51 each having a closed opening are arranged continuously on the serial line along the platform 2A. Those multiple sliding doors 5
Only one of the sliding doors 51 'corresponding to the positions of the doors 61a and 61b is shifted from a stationary position on the series line to the entrance / exit edge 2A by a transfer device (not shown) such as a sliding door hanger. (The sliding door support rail is arranged). Thereafter, the opening / closing drive device obtains control of a logic device (not shown), and the doors 61a, 61b
The sliding door 51 'is moved so as to obtain an opening corresponding to.

[0004]

The above-mentioned conventional opening / closing drive device and sliding door device are excellent in that the door can be opened at an arbitrary position corresponding to vehicles of various train types in which the position of the door is not fixed. The structure and operation control of the device are complicated.
It is necessary to arrange a large number of sliding doors (that is, the sliding doors 51 are arranged almost along the entire length of the platform).
This is because it is necessary to specify and operate the sliding door to be moved in accordance with the position of the entrance door of the train, so that neither the mechanical configuration nor its control is simple. If the configuration and control are not simple, maintenance is frequently performed, and manufacturing costs and maintenance costs tend to increase.

[0005] The present invention is proposed to solve the above-mentioned problems, and enables a passenger to get on and off smoothly even if the entrance is not constant for each train, and is extremely simple to manufacture and maintain. It aims to provide a reliable and reliable platform screen door.

[0006]

According to a first aspect of the present invention, there is provided a platform screen door in which a platform is provided with an inner side and an outer side near an edge portion.
A platform screen door including a screen that is a partition wall and a door that is opened and closed near an entrance / exit of the vehicle so as to be separated from the inside by the train that is stopped. The screen bulges toward the inside of the platform at a portion facing a plurality of approaching / exiting positions (e.g., within a range of 5 to 6 m), corresponding to the fact that each of the entrance / exit positions is not constant. (In other words, when viewed in plan, a part of the line of the screen is expanded toward the inside of the platform), and one or more doors are provided in the expanded part. The length of the bulging portion may be determined so as to cover, for example, the above-described 7 to 8 m in the longitudinal direction of the platform. Further, it is preferable that the space of the bulging portion is of a size that about 10 passengers can stand.

[0007] The platform screen door is first erected near the edge of the platform near the vehicle, and guides passengers on and off by the opening and closing platform door. In a closed state, the platform screen door and the adjacent screen etc. are attached to the traveling vehicle itself. On the other hand, to secure the passengers on the platform against the train wind. If it is long enough to surround the entire area of the platform and high enough to reach the ceiling structure from the floor structure, it also functions as a partition for environmental protection such as air conditioning.

When the train stops next to the platform, there is no problem if there is always a platform screen door in front of the entrance (portion of the side door). It is not always constant. If the train entry / exit position is displaced from the platform screen door, the disembarking passenger must reach the door several meters along the length of the train between the platform edge and the screen. I can't get it. In that case, if the screen is near the edge of the home, it is difficult for the passenger to walk, and if the screen is far away from the home, the space inside the home is narrowed accordingly.

However, this problem is solved together by the platform screen door of claim 1. In this platform screen door, although it may be different for each type of stopped train, it may be different in the approaching range (5 to 6 above).
This is because the screen bulges inside the platform at a portion facing the entrance / exit position for a plurality of entrance / exit positions that fall within the range (m range), and a door is provided at the bulged portion. In other words, with such a configuration, a) even if the train entrance is slightly shifted (within the above range), the passenger can easily pass through the bulging portion without walking along the narrow portion along the edge of the platform. This is because a wide space can be secured inside the platform by reaching the door (or the entrance of the train) and b) providing the screen of the non-bulging portion close to the edge of the platform.

[0010] This platform screen door has a simple structure in which a door that performs a very ordinary opening and closing operation is arranged between screens, which are fixed partition walls, and requires special control. Nothing to do. Therefore, it is easy to manufacture and maintain, is advantageous in terms of cost, and has excellent operation reliability and durability. In this platform screen door,
A bulging portion is provided facing a plurality of approaching entrance / exit positions, but this is determined by providing a separate door for entrance / exit positions that are not approaching. Because. That is, when the entrance / exit is located at a position away from the entrance / exit of another train, another door can be provided at that position without complicating the structure and control. On the other hand, for example, when the entrance / exit position of each train comes within a range of several meters, if doors are individually provided at each position, many doors are arranged in a narrow area and they interfere with contact interference. It is necessary to perform a special control so as to operate smoothly without causing a rise, and this has the same disadvantages as the examples described in each of the above publications. This platform screen door avoided such complexities in equipment structure and control.

[0011] As described in claim 2, when the bulging portion (portion including the door) of the screen has a circular arc with a constant curvature, the screen or the like has a round curved surface, which is preferable in appearance. Also, the area occupied by the screen and the like on the platform is small. If a door having the same curvature as the screen of the bulging portion is formed, it is possible to arrange the door compactly so that the door does not protrude from the screen during opening and closing.

According to a third aspect of the present invention, if the bulging portion of the screen (the portion including the door) has a trapezoidal contour in plan view, it is also preferable in appearance, and the screen and the like are adapted to the surrounding situation. It is not difficult to change the position. Further, since the door can also be formed in a planar shape, manufacturing can be simplified by using commercially available standard parts.

According to a fourth aspect of the present invention, if a door is provided at a portion other than the bulging portion (that is, a flat portion) in a portion where the entrance position at the time of stopping is constant irrespective of the train,
The construction cost of the platform screen door can be reduced. For each train entering the platform, when stopping so that the center entrance / exit is at a certain position, or when the frontmost entrance / exit position is constant in order to keep the leading stop position constant, It is not necessary to bulge the screen up to the part facing the entrance position, and in such a part, a flat door is provided adjacent to the flat screen which does not bulge, thereby eliminating unnecessary cost. Is to reduce.

According to a fifth aspect of the present invention, when a common gantry is fixed near the edge of the platform, and the screen, the door, and the pillar for holding and standing them are provided on the gantry, The installation of the platform screen door on the home becomes easy, and the construction period and cost can be reduced. This is because once the pedestal is level-adjusted (for example, horizontally) and fixed near the edge of the platform, individual level adjustments are not required for columns, doors, screens, and the like. For example, even if the platform floor structure or the like does not have sufficient horizontal accuracy and tilts or undulates, if the pedestal is set at a predetermined level and installed straight, the column provided on the pedestal It is not enough to adjust the level of doors and screens. If an appropriate mounting position of a pillar, a door, a screen, or the like is specified in advance on the gantry, it is not necessary to perform surveying or marking afterwards on the platform at the installation site. When installing a platform screen door in the form of additional work or repair work, as well as new work to install a new platform, construction becomes extremely easy, shortening the construction period and improving the appearance after finishing it can.

If the screen also functions as an emergency door which can be opened and closed and is locked in a closed state, the screen is normally kept closed and a passenger on the platform While the safety of the vehicle is ensured or environmental preservation such as air conditioning is performed, the screen is opened in an emergency (such as when the original door breaks down) so that passengers can enter and exit.

According to a seventh aspect of the present invention, when a video camera or an obstacle sensor is arranged to observe the inside of the bulging portion of the screen, the situation of the passenger in the bulging portion can be checked by a station staff or a vehicle crew. Since it is easy to grasp, for example, when a large number of passengers are concentrated inside the bulging portion, the vehicle waits for departure, and safety can be easily secured even when the space of the bulging portion is small.
