a, 17a.

Next, the third step 18 will be explained. Third
The step step 18 has a parallelogram frame shape, and one end thereof is connected to the second step step 1 by the hinge 16.
A support plate part 4 is rotatably attached to the rotating tips 35, 35 side of the second tread plate 29 of No.
2, and a third footboard 44 which is attached to the other end of the support plate part 42 via a hinge 43 and is able to be inserted over and overlapped with the support plate part 42. The support plate portion 42 is provided with a support plate 45, and one end side of links 47, 47 is connected to the inside of the rotating tip 46 of the third footboard 44 on the left and right sides. One end side of links 48, 48 is connected to the other end side of 47 with an internal pin 48a. And this link 4
The other end sides of 8 and 48 are respectively connected to the upper parts of left and right side plates 42a and 42a of the support plate section 42,
Each pin 48a has elongated holes 49, 4 formed along the longitudinal direction of the links 47, 47 on the other end side.
9, it is said to be able to slide freely. This left and right link 4
Reference numerals 7 and 48 designate a holding device for the third footboard 44 that holds the third footboard 44 horizontally facing outward of the vehicle 1. In addition, the total width W ₃ of the support plate portion 42 is as follows:
It is smaller than the total width W ₂ of the second footboard 29.

Therefore, the third footboard 44 is connected to the support plate portion 42
The third step 44 and the support plate section 42 are superposed and integrated into one body, and the third step 18 is stored on the lower side of the step section 34 of the second step board 29. . On the other hand, when the third step 18 is unfolded and drawn out, the third step 18 is drawn out by the weight of both members and the pushing force of the stopper plates 17, 17, and the support plate portion 42
By abutting the support plate 45 against the holding surfaces 17a, 17a of the footboard 4, the support plate 45 is held vertically downward, and
4 is configured to be held horizontally by left and right links 47 and 48.

However, from the above, the step device 10,
10, in normal times, the third step 18 is stored in the second step 29 of the second step 14, and the second step 14 is stored in the first step 12. As shown in FIG. 5A, it is stored on the floor 9.

The operation of the above configuration will be explained with reference to FIG. 5.

In an emergency, such as when the vehicle 1 has stopped halfway along the track 2 due to a malfunction or the like, the passengers inside the vehicle must first open the emergency door 8 and use the first step device 10 stored on the floor 9 inside the vehicle. Rotating tip 2 of step step 12
Push the 2 and 22 sides counterclockwise in Figure 5 A drawing 1/
The step device 10 is rotated four times to cause the step device 10 to horizontally protrude outward from the vehicle 1 from the emergency exit 11 as shown in FIG. 5B. Next, the passenger lifts up the connecting plate portion 28 of the second step 14 and pushes it toward the outside of the vehicle 1 to knock it down. Then, the connecting plate portion 28 of the second step 14 is rotated about 3/4 rotation counterclockwise in the drawing.
The upper transition plate 31 of the connecting plate part 28 is the first step 1
The first step board 20 of No. 2 is forcefully abutted against the lower surface of the first step board 20, and is held tilted outward by an angle θ from the downward vertical direction.

Furthermore, due to the reaction when the connecting plate part 28 and the first step 12 collide and the urging force of the spring-loaded hinge 15, the second step board 29, which was housed in the holding frame 28, is moved to its rotating tip 35. is rotated about 1/4 turn counterclockwise in the drawing, extended and opened, and held horizontally by left and right links 36 and 37. Then, the second step 29 is biased by the reaction that opens, and the third step 18 falls under its own weight and is rotated 1/4 clockwise in the drawing, and the stop plates 17, 17 are accordingly moved. Torsion coil spring 40, 40
is forced downward and opened. That is, the holding surfaces 17a, 17a of the stopper plates 17, 17 are brought into contact with the support plate 45 of the support plate part 42 of the third step 18, and the support plate part 42 is vertically downwardly moved relative to the second step plate 29. The third footboard 4
The rotating tip 46 of No. 4 is rotated 1/4 counterclockwise in the drawing and held horizontally by the left and right links 47 and 48.

In addition, when storing the stepped device 10 that has been extended, the stopper plates 17, 1 are
7 is folded and the third step 18 is stored in the second step 14, and the second step 14 is stored in the first step 12, and then the whole thing is turned half a turn and the emergency exit 1 is closed.
What is necessary is to store it on the floor surface 9 of 1.

In this way, passengers can
By simply lifting the step steps 14 in order and pushing them down toward the outside of the vehicle 1, the second step step 14 and the third step step 18 are reliably extended, and the emergency exit 11
An emergency evacuation step can be easily and quickly constructed from the floor surface 9 of the vehicle on the running road surface 3, and passengers can safely escape to the running road surface 3. and,
Since the step device 10 has a three-tier configuration and each tier can be stored in the previous tier, the storage space is small in normal times, but in an emergency, each tier can have a safe riser and depth dimension. can be secured.

The above description describes the case of escaping from the vehicle 1 to the running road surface 3, but the first stage step 12
can be used as a gangplank for accessing a rescue vehicle since it can be folded down both inside and outside the vehicle while the second and third steps 14 and 18 are stored.

That is, as shown in FIG. 6, the emergency doors 8 and 10 of the failed vehicle 1 and the rescue vehicle 101 are opened facing each other by stopping the emergency door 101 facing the front of the failed vehicle 1.
8 and fold down the first step 12 of the step device 10 stored in the emergency exit 11 on the side of the failed vehicle 1 as a gangplank toward the emergency exit 111 of the rescue vehicle 101. Passengers can then move from the failed vehicle 1 to the rescue vehicle 101. You can easily and quickly switch sides.

As explained above, according to the vehicle emergency escape step device of this invention, the steps shown in FIGS.
As shown in the figure, when the first tread plate 20 is rotated and held from its vertical position to the horizontal position, the second tread plate 29, the third tread plate 44, and their attached structures are attached to the upper surface of the first tread plate 20. Since the first footboard 20 is stored flat, it has the advantage that the first footboard 20 can be used as a gangplank from a broken vehicle to a rescue vehicle without any problem.

Further, as shown in FIGS. 5C and 5D and FIG.
The spring-loaded hinge 1 is removed by lifting the third treadle 29, 44 upward and rotating it downward.
5 and the stopper 17 biasing springs act to enable the passenger to easily and reliably lower the second and third footboards and escape from the vehicle.

Furthermore, the support plate portions 42 of the second tread plate 29 and the third tread plate 44, which are likely to become unstable, abut against two sides of the plate-shaped stopper 17 and are held at right angles, thereby ensuring safety during escape. gender is ensured.
