DESCRIPTION
Title of the Invention
EVACUATION DEVICE PROVIDED TO RAIL VEHICLE
Technical Field
[OOOI]
The present invention relates to an evacuation device particularly provided
in a rail vehicle that travels along an elevated railway and, in particular, relates to an
evacuation device including a brake that is used for retaining the evacuation device
at a predetermined position (side sliding door) after carrying out the stored
evacuation device, and a wind-up device that is used, after the completion of
evacuation of passengers and so on, for recovering a chute (having a spiral
evacuation path inside), hanging down from the evacuation device, into the
evacuation device.
Background Art
[0002]
When a critical failure, fire, or the like has occurred in a rail vehicle that
travels along an elevated railway, there arises a need to evacuate passengers from
the vehicle. If the vehicle is stopped at a station, the passengers can evacuate to a
platform provided at the station. However, even in the state where there is no
structure such as a platform that can be used for evacuation, for example, when the
vehicle is urgently stopped upon occurrence of emergency while the vehicle travels
between stations along an elevated railway, it is necessary to safely evacuate and
guide the passengers from the stopped rail vehicle.
[0003]
In the case where a composed vehicle travels on one of adjacent tracks of a
double-track elevated railway, a method has been investigated that stops a relief
composed vehicle, on the opposite elevated track, in parallel to the composed
vehicle, then opens side sliding doors, facing each other, of the composed vehicle
and the relief composed vehicle, and then lays an evacuation path (ladder) between
the side sliding doors of both vehicles, thereby evacuating and guiding passengers
from the composed vehicle to the relief composed vehicle. On the other hand, in the
case where a composed vehicle travels on a single-track elevated railway, a method
has been investigated that stops a relief composed vehicle in tandem with the
composed vehicle and then lays an evacuation path (ladder) from a tail car of the
composed vehicle to a lead car of the relief composed vehicle, thereby evacuating
and guiding passengers.
[0 0 041
When, for example, a serious problem has occurred in substation facilities,
supplying power necessary for the rail vehicle operation, due to a large-scale
earthquake or the like, a plurality of rail vehicles running on an elevated railway are
stopped and therefore it is conjectured that a relief composed vehicle is difficult to
operate. Therefore, an evacuation device has been worked out that, not depending
on a relief composed vehicle, allows passengers to safely evacuate to the ground
from a composed vehicle using the evacuation device provided in the composed
vehicle.
[OOOS]
This evacuation device has a feature in that it is disposed inside a rail
vehicle and can be selectively disposed at an arbitrary side sliding door of the rail
vehicle and that it can be fixed to the side sliding door of the rail vehicle with a simple
structure and sequence. The structure of this evacuation device is shown in Patent
Document 1.

Summary of the Invention
Problem to be Solved by the Invention
[0007]
When evacuating to the ground from a rail vehicle stopped on an elevated
railway, first, a crew member or the like on board the rail vehicle takes this
evacuation device out of a keeping (storage) place, then carries the evacuation
device close to a side sliding door selected as an evacuation exit, then opens the
side sliding door, and then positions the evacuation device. Thereafter, the crew
member or the like expands the evacuation device, then fixes the evacuation device
to the side sliding door of the rail vehicle, then expands a chute and so on
incorporated in the evacuation device, and then guides passengers to the evacuation
device to evacuate them to the ground.
[0008]
It is desirable that a device be provided that suppresses the movement of
the evacuation device after the crew member or the like moves the evacuation device
to the predetermined side sliding door and positions the evacuation device at the
predetermined position.
[0009]
In particular, in order to cancel centrifugal force that is applied to the rail
vehicle when passing through a curve, a railway track is canted so that the inner side
of the curve is lowered while the outer side of the curve is raised to allow the rail
vehicle passing through the curve to be inclined inward. Therefore, when the rail
vehicle is stopped at the curve in an emergency, a floor surface on which the
evacuation device is placed is inclined and therefore the device that suppresses the
movement of the positioned evacuation device is required.
[OO I 0]
Further, when, for example, the rail vehicle is stopped on an elevated
railway due to power failure or the like and then the power failure or the like is
restored after the completion of evacuation of passengers and so on, there arises a
need for a crew member to move the rail vehicle to the nearest station. In this event,
the crew member is required to pull up the chute, expanded toward the ground from
the evacuation device, into the rail vehicle and to close the side sliding door.
[OOI I]
The chute includes a spiral slide inside a tubular body and thus is very
heavy and, therefore, it is supposedly difficult to pull up the chute vertically and to
take it into the rail vehicle. In view of this, it is desirable that a device be provided
that allows the chute expanded toward the ground to be easily taken into the rail
vehicle.
[OO 1 21
The evacuation device provided in the rail vehicle should be improved in the
point of suppressing the movement of the positioned evacuation device and in the
point of easily pulling up the expanded chute into the rail vehicle.
1001 31
It is an object of the present invention to provide an evacuation device
adapted to be provided in a rail vehicle operated along an elevated railway, which
can suppress the movement of the positioned evacuation device and which can
easily pull up an expanded chute into the rail vehicle.
Means for solving the Problems
[00 141
In order to achieve the object of the present invention, an evacuation device
according to the present invention adapted to be provided in a rail vehicle is an
evacuation device that is carried from a storage portion of the rail vehicle to an
entrance of the rail vehicle and then disposed at the entrance, wherein the
evacuation device includes: as basic means, a body frame forming the evacuation
device and including a frame body; a wheel disposed at a lower end of the body
frame and enabling the evacuation device to be carried; a holding frame disposed so
as to be rotatable about a horizontal axis provided at the lower end of the body
frame; and a chute provided to the holding frame and having a spiral evacuation path
inside.
Further, the evacuation device according to the present invention adapted
to be provided in the rail vehicle includes: a movement suppression device that
suppresses movement of the evacuation device; and a wind-up device that winds up
a wire connected to the chute.
Advantageous Effect of the Invention
[OO 1 51
According to the present invention, it is possible to provide an evacuation
device adapted to be provided in a rail vehicle operated along an elevated railway,
which can suppress the movement of the positioned evacuation device and which
can easily pull up an expanded chute into the rail vehicle.

[OOI 71
Hereinbelow, an embodiment of an evacuation device according to the
present invention will be described with reference to the drawings.
[OO 1 81
FIG. 1 is a side view of a straddle-type monorail vehicle 10 (hereinafter
referred to as a "monorail vehicle 10") which is given as one example of a rail vehicle.
The rail vehicle is a vehicle that travels guided by a laid railway, and may be a
railway vehicle, a straddle-type (suspension-type) monorail vehicle, a new
transportation system vehicle, or the like. In the present invention, a straddle-type
monorail vehicle is given as an example of a rail vehicle and a description will be
given of a straddle-type monorail vehicle 10 that is operated along an elevated rail
(railway) and provided with an evacuation device at an entrance thereof, an
evacuation device 200 that is provided in the straddle-type monorail vehicle 10, and a
method of fixing the evacuation device 200 to the entrance of the straddle-type
monorail vehicle 10.
[00 1 91
The monorail vehicle 10 shown in FIG. 1 is composed of three cars linked
together and travels on an elevated track girder 2 at a height H from the ground 1.
Each monorail car 10 travels along the track girder 2 while being supported by a
bogie (not illustrated) including support wheels that rotate on an upper surface of the
track girder 2, and guide wheels and stabilizing wheels that rotate on both side
surfaces of the track girder 2.
[0020]
The bogie supporting the monorail car 10 and various devices disposed
under a floor of the monorail car 10 are covered with a skirt 22 provided so as to be
continuous with later-described side structural members 30, thereby suppressing the
propagation of noise that is generated from these various devices.
[002 1 ]
FIG. 2 is an A-A sectional view of the monorail car 10 shown in FIG. 1. The
monorail car 10 is formed by the side structural members 30 provided at both ends in
a width direction of an underframe 20, end structural members (not illustrated)
provided at both ends in a longitudinal direction of the underframe 20, and a roof
structural member 40 placed on upper ends of the side structural members 30 and
the end structural members.
[0022]
The underframe 20 is provided at its lower surface with an underfloor device
chamber in which underfloor devices (not illustrated) such as a main converter, a
transformer, and an auxiliary power supply device are installed. A floor 14 is formed
on an upper surface of the underframe 20. On the floor 14, a storage chamber 100
that stores the later-described evacuation device 200, side sliding doors 34 that open
and close an entrance provided for passengers to get on and off, and so on are
provided.
COO231
FIG. 3 is a B-B sectional view of the monorail car shown in FIG. 2. FIG. 3
shows only one side, in a width direction 270 with respect to a central line 16
extending in a longitudinal direction of the monorail car 10, where the evacuation
device 200 is disposed. The side structural member 30 forming the monorail car 10
is provided with door pockets 32 adapted to receive therein the side sliding doors 34,
34 that are opened and closed when passengers and so on get on and off. A step 24
is provided along an opening/closing direction of the side sliding doors 34 on a side
surface on the car outer side of the underframe 20 at its portion corresponding to
lower ends of the side sliding doors 34.
[0024]
While the side sliding doors 34 shown in FIG. 3 is of a double opening type
in which two sliding doors facing each other are respectively moved along the
longitudinal direction of the monorail car 10, a side sliding door of a single opening
type with a single sliding door may alternatively be employed. A door pocket post 36
is provided vertically on a surface on the car inner side of each door pocket 32 at its
end on the side sliding door 34 side. Although not illustrated, a handrail may be
provided on a surface on the car inner side of each door pocket post 36.
[0025]
The storage chamber 100 in which the evacuation device 200 is stored is
provided on the side of one of the side sliding doors 34. The storage chamber 100
has a rectangular parallelepiped box shape and is provided with a door 120 having a
generally L-shaped in vertical cross section. The evacuation device 200 is taken into
and out of the storage chamber 100 by rotating the door 120 about a rotation shaft
11 0 disposed along one of vertical edges of the door 120.
[0026]
A handrail 38 is provided on the side of the other side sliding door 34 and
chairs 39 are provided on the floor 14 along the longitudinal direction of the monorail
car 10.
[0027]
FIG. 4 is a top view showing a state where the evacuation device according
to the present invention is fixed to the side sliding doors of the monorail car.
[0028]
In an emergency, after confirming that the ground 1 toward which a chute is
to be hung down is appropriate as a landing point and selecting the side sliding doors
34 at which the evacuation device 200 is to be disposed, the evacuation device 200
is taken out of the storage chamber 100 and carried close to the selected side sliding
doors 34. The selected side sliding doors 34 are opened in advance by handling a
door cock or the like that enables the side sliding doors 34 to be manually opened
and closed.
[0029]
Fall prevention plates 230 disposed on left and right both sides in a
longitudinal direction (direction of arrow 272) of the evacuation device 200 are
respectively rotated to the left and right about rotation axes 234 (see FIG. 5) so as to
be opened out and then the fall prevention plates 230 are brought into abutment
against the door pocket posts 36. A silicon rubber or the like is provided at a portion,
brought into abutment against the door pocket post 36, of each fall prevention plate
230, thereby mitigating a shock when the fall prevention plate 230 abuts against the
door pocket post 36.
[0030]
Although not described in detail, the opened fall prevention plates 230 are
each formed with a protrusion projecting in the width direction (direction of arrow 270)
of the monorail car 10 and a size from an outer side of the protrusion of one of the
left and right fall prevention plates 230 to that of the other fall prevention plate 230 is
set slightly smaller than a size between inner sides of the left and right door pocket
posts 36. Since both protrusions of the left and right fall prevention plates 230
described above are restrained between the left and right door pocket posts 36, the
evacuation device 200 is prevented from moving in the direction of arrow 272.
[0031]
The fall prevention plates 230 have both a function of safety preventing
passengers from falling through gaps between the evacuation device 200 and the
opened side sliding doors 36 when the passengers evacuate and a function of fixing
the evacuation device 200 to the monorail car 10.
[0032]
FIG. 5 is a perspective view of the evacuation device according to the
present invention. The evacuation device 200 includes a rectangular parallelepiped
body frame 210 composed of vertical members 212 and transverse members 214,
the fall prevention plates 230 disposed along vertical edges at both ends in a
longitudinal direction (the car longitudinal direction indicated by arrow 272) of the
body frame 21 0, a holding frame 240 that holds a chute 260 (see FIG. 7) having
inside a spiral slide for passengers to slide down and has a footboard 242 (see FIG.
4) adapted to form an evacuation path, and a footboard 222 (see FIG. 4) disposed at
a lower surface of the body frame 21 0.
[0033]
The body frame 21 0 has a rectangular parallelepiped shape such that
frames each formed by combining the vertical members 212 and the transverse
members 214 are disposed to face each other and coupled together. Although not
illustrated, the chute 260 in a folded state is received inside the body frame 21 0.
[0034]
Stoppers 231 for maintaining the state of the fall prevention plates 230
opened to the left and right are disposed along the transverse members 214 provided
at upper portions of the body frame 210. The stoppers 231 are each disposed so as
to be rotatable about a rotation shaft extending along the transverse member 214.
After the fall prevention plates 230 are opened out, the stoppers 231 are rotated to
substantially horizontal positions to thereby maintain the postures of the opened fall
prevention plates 230.
[0035]
The holding frame 240 holding the chute 260 is disposed so as to be
rotatable about a rotation axis 244 extending horizontally at a lower end of the body
frame 210 and, during storage, the holding frame 240 is received in an upright state
by the body frame 210. Wheels 224 are provided under the transverse members 214
forming the lower surface of the body frame 21 0 so that the evacuation device 200
taken out of the storage chamber 100 can be easily carried in the car to arbitrary side
sliding doors 34. The wheels 224 are provided at four positions in total and each
wheel 224 is fixed to a lower portion of the transverse member 214 via a joint that is
rotatable in a horizontal plane.
[0036]
FIG. 6 is a side view of the evacuation device according to the present
invention and is a diagram showing the structure of a movement suppression device.
A movement suppression device 300 includes a handle 302 provided to the vertical
member 212 forming the evacuation device 200, a handgrip 304 provided inside the
handle 302 so as to be graspable by a crew member or the like, a wire 306
connected to one end of the handgrip 304, a lever 31 0 connected to the wire 306, a
shaft 315 connected to the lever 310, a spring 316 disposed such that the shaft 315
passes therethrough, and an abutment portion 317 that is pressed by the spring 316
so as to be brought into abutment against the floor 14.
[0037]
The handgrip 304 provided at a portion surrounded by the handle 302 has a
generally L-shape formed by long-piece and short-piece two bars connected together
and is rotatable at a connecting portion of the bars about an axis extending in the
direction of arrow 272. A grasping portion where the long-piece bar is grasped (the
handgrip 304) is configured such that this grasping portion can be easily grasped
even in the state where the crew member or the like carrying the evacuation device
200 to a predetermined position holds the handle 302.
[0038]
The wire 306 is connected to an end of the short piece of the handgrip 304.
The wire 306 connected to the short piece extends vertically downward along the
vertical member 212 forming the evacuation device 200, then changes its direction
by a pulley 308 disposed near a connecting portion of the vertical member 212 and
the transverse member 214 to extend horizontally along the transverse member 214,
and then is connected to the lever 310. The pulley 308 is disposed so as to be
rotatable about an axis extending in the direction of arrow 272.
[0039]
The lever 310 has, like the handgrip 304, a generally L-shape formed by
long-piece and short-piece two bars connected together and the wire 306 is
connected to an end in a longitudinal direction of the long-piece bar.
[0040]
A connecting portion of the long-piece bar and the short-piece bar forming
the lever 31 0 is rotatably attached to an upper end of a lever support portion 31 1
extending vertically from an upper portion of an attaching portion 312 provided to the
transverse member 214 disposed at a lower portion of the evacuation device 200.
[0041]
The attaching portion 312 is provided with a spring receiver 314 extending
horizontally from the attaching portion 312. The spring 316 that generates a vertical
spring force is disposed under the spring receiver 314 and the abutment portion 317
that is brought into abutment against the floor 14 is disposed at a lower end of the
spring 316.
[0042]
The shaft 31 5 extends vertically upward from an upper end of the abutment
portion 317. The shaft 315 passes through the spring 316 and the spring receiver
314 and is connected at its forward end to an end in a longitudinal direction of the
short-piece bar of the lever 31 0.
[0043]
In the state where the crew member or the like does not grasp the handgrip
304, since the spring 316 presses the abutment portion 317 against the floor 14, the
movement of the evacuation device 200 is suppressed due to a friction force
between the abutment portion 317 and the floor 14 (the same as the state where the
evacuation device 200 is stored in the storage chamber 100).
[0044]
When moving the evacuation device 200 to a predetermined position, the
crew member or the like grasps the' handle 302 and the handgrip 304 so that the
short piece of the handgrip 304 is raised. By this operation, the wire 306 pulls the
end of the long-piece bar of the lever 310 in the direction of arrow 270 so that the end
of the short-piece bar of the lever 310 is raised. Since the shaft 315 connected to the
short-piece bar of the lever 310 is pulled up vertically, the spring 316 pressing the
abutment portion 317 against the floor 14 is compressed so that the abutment portion
317 moves away from the floor 14 to release the friction force (braking force).
Accordingly, the crew member or the like can easily carry the evacuation device 200.
Likewise, when the grasping of the handgrip 304 is stopped, the abutment portion
317 is pressed against the floor surface 14 by the spring 316 so that a braking force
(movement suppressing force) is exerted to suppress the movement of the
evacuation device 200. This braking force is not only used as braking when
positioning the evacuation device 200, but also used as braking for suppressing the
movement of the evacuation device 200 whose movement has been completed.
[0045]
By providing the evacuation device 200 with the movement suppression
device 300 having the structure described above, it is possible to suppress, even
inside the storage chamber 100, the movement of the evacuation device 200 due to
vibration or the like caused by running of the rail vehicle 10. Further, the evacuation
device 200 carried to predetermined side sliding doors 34 from the storage chamber
100 can be retained at a predetermined position to prevent the movement thereof.
These effects can be exhibited even when the monorail car 10 is stopped at a cant
curve in an emergency or when the monorail car 10 is inclined due to puncture in an
emergency.
[0046]
If the abutment portion 31 7 is provided near the wheel 224, located near the
center of gravity of the evacuation device 200, among the wheels 224 movably
supporting the evacuation device 200, a high compression force can be provided to
the spring 316 that imparts a friction force to the abutment portion 317 and therefore
the abutment portion 316 is allowed to obtain a high friction force relative to the floor
14. Accordingly, the movement of the evacuation device 200 placed at a
predetermined position can be suppressed more effectively.
[0047]
FIG. 7 is a side view (view on arrow C-C of FIG. 4) in the state where the
evacuation device shown in FIG. 4 is fixed to the monorail car. When the holding
frame 240 provided in the evacuation device 200 is expanded in a push-out direction
from the car inside to the car outside, the holding frame 240 having the footboard 242
(see FIG. 4) is maintained substantially horizontal by wires 250 connecting between
upper end portions of the body frame 21 0 and forward end portions of the holding
frame 240. The folded chute 260 received in the body frame 21 0 is extended while
descending so that an evacuation path is formed starting from the footboard 222 (see
FIG. 4) and reaching the chute 260 via the footboard 242.
[0048]
A wind-up device 400 that is used by the crew member or the like for pulling
up the extended chute 260 into the monorail car 10 after the completion of
evacuation of passengers and so on is provided at an upper portion of the transverse
member 214 forming the evacuation device 200. Using the wind-up device 400, the
crew member or the like can easily pull up the heavy chute 260 into the monorail car
10. A wire 401 connected to an outer peripheral surface of the chute 260 is
connected to the wind-up device 400 via a "SURODAN" (registered trademark)
hanging arm 31 provided at an upper portion of the side structural member 30 of the
monorail car 10.
[0049]

404 disposed at an end in a longitudinal direction of a horizontal piece forming the
frame 400, a wind-up roller 406 disposed at a joining portion of the horizontal piece
and a vertical piece of the frame 400, a tension roller 408 disposed at an upper end
of the vertical piece of the frame 400, a pressing roller 41 0 forming a pair with the
tension roller 408, and a large handle 412 connected to the wind-up roller 406.
[0051]
FIG. 10 is a sectional view (D-D section of FIG. 9) of the wind-up device
shown in FIGS. 8 and 9.
In order to allow the wind-up device 400 to be easily fixed to the evacuation
device 200, a pin 414 (see FIG. 8) is provided on a lower surface at one end in the
longitudinal direction of the horizontal piece of the frame 402 and a fixing portion 416
is provided at the other end thereof.
[0052]
The fixing portion 416 includes a restraining tool 420 having a rectangular
open portion, a screw portion 424 extending horizontally to pass through the
restraining tool 420 and the transverse member 214 forming the evacuation device
200, and a small handle 422 for rotating the screw portion 424. The restraining tool
420 is fixed to the end of the horizontal piece of the frame 402 by bolts 418.
[0053]
The transverse member 214 of the evacuation device 200 is provided with,
at its upper surface, a hole 215 (see FIG. 5) into which the pin 414 of the wind-up
device 400 is inserted, and with a screw seat 216 (see FIG. 5) into which the screw

First, the pin 414 of the wind-up device 400 is inserted into the hole 215 and then the
rectangular open portion of the restraining tool 420 forming the fixing portion 416 is
fitted over the transverse member 214 having a rectangular section from the side of
the transverse member 214. Then, rotating by the small handle 422, the screw
portion 424 provided in the fixing portion 416 is screwed into the screw seat 216
provided at the side surface of the transverse member 214. By the steps described
above, the wind-up device 400 is firmly fixed to the upper portion of the evacuation
device 200.

The wire 401 connected to the outer peripheral surface of the chute 260 is
taken into the monorail car 10 via the four rollers provided in the wind-up device 400,
that is, the front end roller 404, the wind-up roller 406, the tension roller 408, and the
pressing roller 41 0. Although not illustrated, the pressing roller 41 0 presses the wire
41 0 passing between the tension roller 408 and the pressing roller 41 0 by means of a
spring.
[0055]
The wire 401 is wound around a cylindrical surface of the wind-up roller 406
by one turn so as to increase a friction force between the wind-up roller 406 and the
wire 401, thereby making it possible to surely wind up the wire 401 by the wind-up
device 400. In view of this, a recess into which the wire 401 is fitted is formed around
the cylindrical surface of the wind-up roller 406, thereby preventing coming-off of the
wire 401 wound by one turn.
[0056]
A pulley 407 and the large handle 412 are mounted on a shaft by which the
wind-up roller 406 is rotatably supported. Likewise, a pulley 409 is mounted on a
shaft by which the tension roller 408 is rotatably supported. Since the pulley 407 and
the pulley 409 are coupled by a crossed belt 41 1, the wind-up roller 406 and the
tension roller 408 can be rotated synchronously by rotating the large handle 412.
The pulley 407, the pulley 409, and the crossed belt 41 1 are covered with a cover
413.

With this structure, the wire 401 is efficiently taken into the monorail car 10
without sliding on the cylindrical surfaces of the rollers forming the wind-up device
400. Therefore, by rotating the large handle 412 of the wind-up device 400, the
heavy chute 260 connected to the wire 401 can be pulled up vertically and taken into
the monorail car 10. Since the wind-up device 400 is provided at the upper portion of
the evacuation device 200, the crew member or the like who operates the large
handle 412 can work in an appropriate working posture. Therefore, the chute 260
can be taken into the monorail car 10 in a short time with no great effort required.
[0058]
In FIG. 7, the example is shown in which the wire 401 is hung on the
"SURODAN" hanging arm 31. However, the wire 401 is not necessarily hung on the
"SURODAN" hanging arm 31. Further, small unevenness may be provided on the
surface, which is brought into contact with the wire 401, of the wind-up roller 406,
thereby winding up the wire 401 more surely.
The wind-up device 400 may be stored separately from the evacuation
device 200 in the storage chamber 100 or the like and may be fixed to the evacuation
device 200 as necessary and used for taking the chute 260 into the car.
