Description

Description: TECHNICAL FIELD The present invention relates to a door device for a railway platform. In particular, the present invention relates to a door device for a railway platform in which a partition such as a wall or a fence is formed on a side facing a track, and an opening / closing door is provided at a platform position.

[Prior art] For the safety of passengers and to improve the air-conditioning efficiency of the platform, partitions are formed with walls and fences on the side facing the track of the railway platform, and they are opened and closed at the train entry / exit position. It has been proposed to provide a door.

As an example of the above, there is a door device (January 16, 1982) at the landing of Japanese Patent Publication No. 57-2537, which has a wall or fence at the landing and a double door at the entrance. Also, JP-A-56-103649 railway equipment (August 18, 1981)
This shows an example in which a large number of entrances and exits are provided at one landing.

[Problems to be solved by the invention]

When dealing with a large number of passengers, as with many vehicles, it is desirable to have a double-drawing type door that opens on both sides.

Also, in railways that handle a large number of passengers, many entrances are provided in the vehicle to increase the speed of getting on and off. As a result, the distance between the adjacent entrance and exit is reduced.

On the other hand, the width of the entrance on the platform side must be set to be larger than the width of the entrance of the vehicle in accordance with the stop error of the vehicle.
Therefore, the door provided here is wide, and when the door is opened by being drawn, the door bottom strokes to a far position.

As described above, when the distance between the adjacent entrance and exit is small, both door ends interfere with each other. Alternatively, it is conceivable that an inconvenience such as narrowing the width of the entrance / exit of the other party is caused. There are many opportunities for this problem to occur especially at the crew entrances provided in close proximity.

Neither of the two cases described above as the prior art mentions the distance between the adjacent entrance and exit, and there is no suggestion of a means for coping with the problem, which remains as a problem to be solved.

In addition, there is a problem that the structure must not be too complicated in practical use in solving this problem.

[Means for solving the problem]

In order to solve the above-mentioned problems, in the present invention, in a door device for a partition of a landing hall provided on a side facing a track of the landing hall, a partition having a plurality of entrances for passengers and crewmembers is provided. A door provided at the passenger entrance / exit has a sliding door structure which is opened and closed by being moved substantially in parallel in the plane of the door. Further, a door provided at the passenger entrance / exit adjacent to the passenger entrance / exit in the partition is partially opened toward the passenger entrance / exit, and the rest is provided in the opposite direction in the plane of the door. And a double-door structure that is opened by being moved substantially in parallel, and the door that is opened toward the crew entrance and exit comprises a plurality of doors, and the plurality of doors are one door when the door is opened. Has a multi-door structure in which it is stored over other doors. In this case, of the plurality of doors opened toward the crew entry / exit, the door having the maximum opening / closing movement stroke is a driven door directly driven by the door driving device, and the other doors are the aforementioned doors. The driven door is driven by the stroke of the driving door. Further, stoppers are provided at both open and closed stroke ends of the driven door, and a buffer element is interposed between the driven door and the driven door.

[Action]

(1) In the present invention, a door provided at a place where a space between adjacent entrances and exits of a partition provided on a side facing a track of the entrance / exit is provided with a multiple door structure is provided. The two doors make the full stroke for opening, but the width of the doors is so narrow that the door position at the time of opening does not become far. Furthermore, the strokes of the doors other than the multiple doors are small. Therefore, the substantial stroke of the door end of those doors is small, and there is no interference between the door ends of adjacent entrances, and the effective width of the adjacent entrances is not hindered.

(2) In the new door driving device of the present invention, a special driving device for a multiple door is not provided, and a driven door is moved by a stroke of a driven door directly driven from the door driving device. Since a shock absorbing element such as an air damper or rubber is interposed between the driven door and the driven door, it acts to reduce the impact at the time of starting or stopping. Thus, the multiple doors can be smoothly driven with the simplicity of adding a buffer element.

〔Example〕

 The present invention is described by the following examples.

FIG. 1 is a plan view showing a state where a vehicle is stopped at a landing according to an embodiment of the present invention. (A) when the door of the entrance is still closed, and (b) when the door of the entrance is open.
Shown in Reference numeral 1 denotes a vehicle that forms a train by knitting, and 2 denotes a double-pulled door at a side of a vehicle on which a passenger gets on and off, and the width of the door is a. Reference numeral 3 denotes a door at the entrance of the vehicle on which a crew member gets on and off and has an inward opening structure. Reference numeral 4 denotes a boarding / alighting platform, and reference numeral 5 denotes a partition provided on the side facing the track of the boarding / alighting platform, which is a wall-shaped member including glass. Numeral 6 denotes a sliding door provided at the entrance, and its width is b. Reference numerals 7 and 8 denote a pair of sliding doors provided in a place where the adjacent entrance is close to each other, and have a double door structure in which 7 and 8 are overlapped and stored when opened. Reference numeral 9 denotes a door for a crew member provided on the boarding side, which has an inward opening structure to the boarding side.

The opening size 2c of the door for passenger entry / exit of the vehicle is roughly equal to 2a when the overlapping dimension of the door end when the door is closed is ignored, and the door end position d when the door is opened is also 2a and 2c. The opening size 2e of the passenger entry / exit door at the landing is roughly equal to 2b, ignoring the overlapping size of the door end when the door is closed, and the door end position f when the door is opened.
Is also 2b. The opening size 2e on the platform side is the opening size on the vehicle side
It is set to be larger than 2c to secure an effective width that can be used for getting on and off even if there is an error in stopping the vehicle,
Assuming that the stop error amount to be covered is r, e = c + r, f = 2e,
d = 2c, and f = d + 2r. That is, the door bottom position of the door on the boarding side is twice as large as the stop error amount r than the door bottom position of the vehicle door.

Therefore, if the distance between adjacent entrances is 2d or more,
When it is 2f or less, no interference of the door end of the vehicle door occurs, but interference of the door end of the entrance / exit side door occurs.

When crew entrances and the like that are not arranged at equal intervals are within the door bottom position f of the door on the boarding / alighting side, the effective width thereof is narrowed.

In order to avoid the interference of the door butt and the narrowing of the effective width, it is necessary to take a special structure so as to reduce the position of the door butt. For this reason, in the present embodiment, when the doors on the side of the passengers close to the doors for the crew members are opened in a double structure, the doors 7 and 8 are stored in an overlapping manner when the doors are opened. The position of the buttocks is f
The value of g is made smaller. That is, if the widths of 7 and 8 are set equal, each width is e / 2,
The door bottom position g is g = e + e / 2 = 1.5e, which is smaller than f = 2e (described above) by e / 2.

Although the width i of the crew entrance on the boarding side is set to be larger than the width h of the crew entrance on the vehicle side, in this embodiment, the centers do not match due to the relationship with the adjacent passenger entrance. When the vehicle is stopped, the effective width is narrowed when there is an error to the right, and even if practically possible, it may be difficult for a crew member to get on and off.

FIG. 2 is a side view of FIG. 1 with each door closed. Ten
Numeral denotes a pillar for supporting the partition, and numeral 11 denotes a headgate portion in which a door support rail and a door driving device are stored.

Fig. 3 shows a triple door structure with three doors on the near side, 7, 8, 8 ', so that the door at the time of opening the door is as close as possible, and the center of the entrance for the crew is on the vehicle side And the boarding side. (A) shows a state where the door is closed, and (b) shows a state where the door is open. The width of multiple doors 7, 8, 8 '
Assuming // 3, the position of the door end i is (1 + 1/3) e.

FIG. 4 is a side view showing an embodiment in which a known multiple door driving device is used in carrying out the present invention shown in FIG. 1, and each of the doors 6, 7, and 8 is attached to a door support rail 12. Door car 13a, 1
Suspended and supported by 3b and 13c. Wheel 15 and driven wheel 16 driven by a motor 14 including a gearing
The arm 18 grasps the lower side of the belt, and the arm 18 is attached to the driven door 6 so that the movement below the belt and the movement of the driven door 6 are integrated. The arm 19 grasps the upper side of the belt, and the arm 19
, The movement of the upper part of the belt and the movement of the driven door 7 are integrated. When the lower part of the belt moves to the left by the rotation of the motor 14, the upper part of the belt naturally moves to the opposite right. Each door opens. A belt 22 between a wheel (small diameter) 20 coaxially rotating with the wheel 15 and a driven wheel 21 corresponding thereto.
The arm 23 grasps the upper side of the belt, and the arm 23 is attached to the driven door 8. The width of the door 7 and the door 8 is the same, whereas the diameter of the wheel 20 is
The door 8 makes a half stroke during the full stroke of the door 7 due to the half of the diameter of the door, and the doors 7s and 8s coincide with each other when the door is completely opened, so that the door butt position can be adjusted. It serves the purpose of staying away. However, the driving method of the double door used here is complicated in that a wheel and a belt are separately used, and a decrease in reliability due to the complexity remains as a defect.

The double door has overhangs 7h and 8h so that it can be stably supported by the door support rail, and 7h and 8h are doors 7s and 8
Although it protrudes from the s, it is higher than the height of the person, so it does not hinder crew getting on and off.

FIG. 5 is a side view showing another embodiment of the present invention. In the case of FIG. 4, another wheel and a belt are provided for driving the door 8, whereas this embodiment is directly connected to the belt 17 via the arm 25. The door 8 is driven by the movement of the door 7 which is driven by the arm. The moving force is the arm attached to the door 8 from the arm 25 via the air damper 24.
Communicated via 26. Since the air damper utilizes gas force, a force is generated by the relative speed of the doors 7, 8. Therefore, since no force is generated until the relative speed is generated, the driven door 8 starts later than the driven door 7 driven directly from the belt. As a result, a smooth operation having a buffering action between the two doors can be obtained. Also, unlike the air cylinder, the air damper only needs to generate force according to the relative speed, so it does not need high airtightness, and from this point it can be used practically without high quality and frequent maintenance. It is simpler and cheaper than those using wheels or belts. Note that the driven door 8 needs an open-side stopper 27 and a closed-side stopper 28 to determine its stroke. Rubber or the like is used for this stopper.

2. Description of the Related Art Japanese Patent Laid-Open No. 2-53478 discloses a drive device using a screw in a drive device for an automatic opening / closing door (April 18, 1990).
