Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable platform fence device that stands upright along a side edge on a platform and forms a wall with a train stopped at a fixed position on a track side extending alongside the platform.

[0002]

2. Description of the Related Art In the recent railway passenger industry, one-man operation of trains has been promoted from the viewpoint of labor cost reduction and the like.
Along with this, it was necessary to provide a movable platform fence device and the like on the platform to ensure the safety of passengers using the train.

[0003] A conventional movable platform fence device is provided with a pair of entrance and exit doors that open and close, open and close to and away from each other, corresponding to the position of the passenger door of a train stopped at a fixed position on the track side. At both sides of the door, a door pocket fence for accommodating each door when the door is opened is fixed on the platform.

Normally, a train stops at a predetermined fixed position, but an error within a predetermined allowable range with respect to the reference fixed position is allowed. Therefore, the opening amount of the pair of entrance / exit doors in the movable platform fence device, that is, the frontage of the double door fences, is set wider than the opening frame width of the passenger door on the train side in consideration of the stop error of the train.

[0005] Even in a platform provided with such a movable platform fence device, as long as the train stops within the allowable range, in the event of an accident or the like, in the event of an emergency, the passenger door on the train side and the movable platform fence device side The passengers were able to evacuate outside the train through these overlapping openings.

[0006]

However, if the train stops beyond the allowable range, a displacement occurs between the position of the passenger door on the train side and the frontage of the movable platform fence device. Would. At this time, if the train cannot run on its own, the door pocket fence becomes an obstacle, and there is a possibility that the evacuation of passengers in an emergency may be hindered.

As a countermeasure against such an emergency, recently, the door fence is not fixed to the platform so as not to move. For example, the door fence is supported so as to be rotatable in a horizontal direction with one side end as a center of rotation. Ideas have been proposed. This is to provide a shaft rotation mechanism at the side edge of the door pocket, and after releasing the restraint of the door pocket, rotate the entire door pocket horizontally about the axis as a fulcrum about 90 degrees with respect to the home surface to secure an evacuation passage. It is assumed that.

However, as can be seen at many stations, the platform has a narrow width due to architectural structural reasons, such as pillars being built near the end of the platform or side walls of stairs or waiting rooms. Often.

In such a limited space,
As described above, in order to rotate the entire door pocket horizontally with respect to the home surface, since the radius of rotation becomes large, the range in which the door pocket can be rotated is restricted. Therefore, it is necessary to secure a sufficient evacuation passage. There was a problem that it was difficult.

Further, in order to secure the evacuation passage as much as possible, the door pocket fence is fully rotated until it comes close to the pillar or the side wall of the stairs. Therefore, this time, the passage on the platform is blocked by the door pocket fence, causing a problem that the passage of passengers is hindered, and there is a possibility that a sufficient function for emergency use may not be exhibited.

Further, in the case where the door fence is displaceably supported, for example, by rotating the door fence, the door fence must be fixed with a considerable strength so as not to move easily in order to ensure safety at normal times. On the contrary, at the time of emergency evacuation, the door fence must be able to be easily and quickly displaced. The development of a lock device dedicated to a movable platform fence device that can satisfy these conflicting demands has also been desired.

The present invention has been made in view of the above-mentioned problems of the prior art, and the door fence can be largely displaced within a limited space, which hinders the passage on the home side. A sufficient evacuation path can be ensured, and the door pocket fence can be supported on the platform with strong support strength in normal times, while the door pocket fence can be easily and quickly displaced in an emergency.

Here, the hook portion 81 which is the uppermost end of the engaged member 80 and to which the engaging portion 72 of the striker 71 is engaged / disengaged is disposed so as to be located substantially on the same plane as the floor surface of the platform 1.

Next, the operation will be described. As shown in FIG.
In the movable platform fence device 10, except when passengers get on and off the train 2, the doors 20 extend laterally beyond the door pocket fence 11. That is, the entrance door 20 is maintained in a closed state that covers the opening frame 3a of the passenger door 3 of the train 2 that stops at the fixed position on the track side.

On the other hand, when the passenger gets on and off the train 2, the getting-on / off door 20 is moved in the direction of retracting to the door pocket fence 11 side.
The door 20 moves laterally from the front of the passenger door 3 of the train 2 and is stored in the storage section 12 of the door pocket fence 11 as it is. The door 20 is opened and closed by rotating the screw member 31 in the forward and reverse directions by the electric motor 33 of the door drive unit 30.

The door pocket fence 11 of the movable platform fence device 10 is different from the support fence 11 a fixed on the platform 1.
Although it is displaceably supported via a connecting mechanism, it is normally restrained by a lock device 40 so as not to be displaced at a normal position substantially aligned with the support fence 11a. Therefore, the normal door fence 1
1 does not displace inadvertently, and the safety of passengers on the platform 1 is ensured.

As shown in FIG. 1, when the train 2 stops beyond the allowable range of the stop error, a displacement occurs between the position of the door 3 on the train 2 and the movable platform fence device 11. The door pocket fence 11 stands in front of the door 3. In such a situation, when it is necessary to evacuate out of the train 2 urgently, release the restraint of the door pocket fence 11 by the lock device 40 and displace the door pocket fence 11 to secure an evacuation passage. I just need.

The connection mechanism is a fixed side door fence 11
The side edge of the door pocket fence 11, which is the movable side, is displaceably connected to the side edge of "a" at an interval. According to this connection mechanism, the door pocket fence 11 is moved from the normal position to the side position near the support fence 11a on the platform 1 from the normal position while maintaining the door fence 11 substantially parallel to the support fence 11a. Can be displaced.

More specifically, in FIG. 2, each link member 101, 102 of the link unit 100 is
It rotates substantially at right angles to the home 1 side with respect to 1a. Accordingly, the door pocket fence 11 rotates with respect to each of the link members 101 and 102 so as to maintain a state parallel to the support fence 11a. The door pocket fence 11 is finally connected to each link member 10.
It moves parallel to the platform 1 side from the support fence 11a by the length of 1,102, and is maintained at a lateral position shifted to the side near the support fence 11a.

With such a displacement mode of the door pocket fence 11,
The door pocket fence 11 is shifted laterally from the front of the door 3 on the train 2 side, and the width from the side wall of the train 2 to the side of the door pocket fence 11 is widened. Therefore, it is possible to secure a sufficiently large evacuation passage (indicated by a dashed-dotted arrow in FIG. 2).

Further, since the door pocket fence 11 is displaced substantially parallel to the support fence 11a, a substantial moving space required for the displacement of the door fence 11 is small, and even when the width of the platform 1 is narrow, the home fence 11 can be moved. A moving path for passengers on the platform 1 can be secured at the same time without interfering with other structures such as pillars and stair sidewalls on the platform 1. In the present embodiment, the structure of the connecting mechanism is simple, and the manufacturing is easy.

In order to restrain the door pocket fence 11 by the lock device 40, first, in FIG. 9, the second pivot 60 that is pivotally supported by the link member 61 is made rotatable by loosening the detent bolt 62. . Next, the link member 61 and the striker 7
The hook 1 is engaged with the hook portion 81 of the engaged member 80 while the hook 1 is in a substantially vertical state.

At this time, the operation lever 51 is moved to the first position in FIG.
It is rotated counterclockwise about the pivot 50 to a position inclined obliquely to the upper left. That is, as shown in FIG. 14, the center 73a of the fitting hole 73, which is the center of rotation of the striker 71, may be moved to a position beyond the toggle forming line L (the right side in FIG. 14).

As a result, the striker 71 of the striker 71, which extends substantially vertically downward from the second pivot 60, engages with the hook 81 of the engaged member 80 on the platform 1 upward. Locked state. In FIG. 14, the striker 71 is fixed at a position where the rotation center 73a is inclined counterclockwise by an angle θ with respect to the toggle forming line L extending substantially vertically. Therefore, the striker 71 does not move to the unlocking side of the toggle forming line L due to slight vibration or the like, and is stably maintained in the locked state.

As shown in FIG. 14, the second pivot 60
Is formed with a cam outer peripheral portion 60 b, and the cam outer peripheral portion 60 b is fitted into the fitting hole 73 of the striker 71. Therefore, the center 73a of the fitting hole 73, which is the center of rotation of the striker 71, is eccentric with respect to the axis 60a of the second pivot 60. Here, by rotating the axis 60a of the second pivot 60 counterclockwise, the striker 71 in the locked state is further engaged with the hook portion 81 of the engaged member 80 by the eccentric distance X. To be displaced upward.

The eccentric distance X may be a small value in consideration of the adjustment allowance for the mounting error. If the locking bolt 62 of the link member 61 is tightened and fixed, and the second pivot 60 integral with the link member 61 is rotated, a wedge action acts on the striker 71 side. A strong holding force is generated between them. Therefore, when the door pocket fence 11 is fixed with bolts or the like, the same fixing force can be obtained, and the door pocket fence 11 can be more securely and firmly restrained on the platform 1.

When the lock device 40 is locked as described above, the foot pedal 90a on the operation end side of the kick lever 90 shown in FIG. 7 is folded to the storage position against the urging force, and Cover opening 17a of door pocket fence 11
You can close it with 7. Thereby, the substantial storage space for the foot pedal 90a is small, and the foot pedal 90a can be stored in a limited space in the door pocket fence 11.

On the other hand, in order to release the constraint of the door pocket fence 11 by the lock device 40, first, as shown in FIG.
Open the cover 17 of the opening 17a provided in 1. Then, the foot pedal 90a provided on the kick lever 90
Is pushed out of the opening 17a by the urging force of the urging means and swings to the use position. Therefore, in order to quickly release the locked state of the lock device 40, the kick lever 90
Can be easily swung by depressing the foot pedal 90a.

One operation of depressing the kick lever 90 causes the pair of lock devices 40, 40 to be connected to the connecting bars 91, 9
2 can be unlocked at the same time. That is, when the kick lever 90 is depressed, in the lock device 40 on the left side in FIG. 7, the operation lever 51 and the link member 61 rotate clockwise about the first pivot 50 together.

At this time, when the striker 71 relatively rotates about the second pivot 60 fixed to the link member 61, the holding force of the engaging portion 72 on the engaged member 80 side is increased. To be released. Here, since the range of rotation of the striker 71 is restricted by the support connecting pipe rod 45, the striker 71 is displaced to a horizontal position as shown by a two-dot broken line in FIG.

The engaged member 80 fixed to the platform 1 has a hook portion 81 at the uppermost end thereof.
It is located on substantially the same plane as the floor surface of the platform 1.
As a result, there are few projections on the floor surface,
There is no possibility that the passenger is accidentally hooked on the engaged member 80. The lock device 40 on the right side in FIG. 7 is also unlocked similarly.

FIG. 15 shows a modification of the lock device 40. The lock device 40A according to this modification includes a base member 41, an operation lever 51A, and a link member 61.
, A striker 71 and an engaged member 80. Even when a pair of such lock devices 40A are provided at both ends of the lower end portion of the door pocket fence 11, restraint and restraint release operations are individually performed without interlocking with each other.

The operation lever 51A is connected to the kick lever 9
On the operation end side, a foot pedal 54 swings through a pivot pin 53 between a retracted position along the operation end and a use position extending laterally from the operation end. It is movably provided. The foot pedal 54 may be set so as to protrude outward from the opening 17a when the cover 17 of the door pocket fence 11 is opened.
