DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, the same parts as those in FIG. 13 are designated by the same reference numerals and detailed description thereof will be omitted. FIG. 1 is a diagram showing a configuration of a car according to the present embodiment, which is different from FIG. 13 in that a foldable ladder 21 is provided on the side of the car, and an escaper 22 is a ladder between the side of the car and the ladder 21. The point is to extend the ladder 21 to the extent that 21 can be climbed.

Specifically, this ladder 21 is a ladder main body 2 in which a step bar 23 is continuously provided as shown in FIGS. 2 and 3.
4 is attached to the side surface of the car by a parallel link mechanism 25 which horizontally translates 4 and extends from the side surface of the car. The ladder main body 24 includes an upper car room 3 and a lower car room 4.
It is installed in four places, the upper part and the lower part.

The parallel link mechanism 25 pivotally supports one end of a pair of parallel links 26, 27 on the side surface of the car so as to be horizontally rotatable, and the parallel links 26, 2 are also supported.
At the other end of 7, the both sides of the ladder main body 24 are rotatably supported in the horizontal direction.

One end of a link guide 28 is rotatably attached to the intermediate portion of the parallel link 27. A pin 30 is provided at the other end of the link guide 28. On the other hand, a guide member 29 is provided on the side surface of the car so as to project from the side surface, and a slit 29a is formed on the guide member 29 along the side surface of the car. In this guide member 29, the pin 30 of the link guide 28 has the slit 2
It is attached so as to be slidable along 9a.

When the pin 30 of the link guide 28 moves along the slit 29a of the guide member 29, the parallel link 27 rotates in the horizontal direction, and when the pin 30 moves to one end of the slit 29a, the side surface of the car is moved. It is designed to be almost perpendicular to. As a result, the ladder main body 24 is moved in parallel in the horizontal direction so as to project from the side surface of the car. The parallel links 26 and 27 are formed to have a length such that a person can climb between the side surface of the car 1 and the ladder body 24. In this way, the extended ladder main body 2 can be climbed up with the side surface of the car 1 as the back.

The slit 29a is provided at one end of the slit 29a.
A stop hole 29b is formed continuously in a direction perpendicular to the direction a. When the pin 30 of the link guide 28 enters the stopper hole 29b, the parallel link 27 is fixed in a state of being substantially perpendicular to the side surface of the car.

As shown in FIG. 1B, the lengths of the parallel links 26 and 27 are set so that the escaper 22 can climb up with the ladder body 24 as the back of the car body. Further, the length of the ladder main body 24 is formed so as to extend above the ceiling of the upper car room 3 from the lower part of the side rescue outlet 6 of the lower car room 4.

At the lower end of the ladder main body 24, a rectangular step 35 forming a bottom surface between the ladder main body 24 and the side surface of the lower cab 4 is foldably provided as shown in FIGS. ing. That is, at both ends of the ladder main body 24,
One side of the step 35 is attached rotatably around the width direction of the step 35.

A side of the step 35 facing the mounting side is bent upward, and one end of a step guide 36 is vertically rotatably attached to a substantially middle portion of the side side. A pin 37 is provided at the other end of the step guide 36, and the pin 37 is attached so as to be vertically slidable along the slit 38a.

The slit 38a is formed in a guide member 38 that is vertically attached to the side of the ladder body 24 so as to protrude toward the car. When the pin 37 of the step guide 36 moves along the slit 38a of the guide member 38 to rotate around the width direction of the step 35 and the pin 37 moves to the lower end of the slit 38a, the ladder main body 24
It is designed to be almost perpendicular to. This step 35
Thus, a bottom surface is formed between the ladder body 24 and the side surface of the lower cab 4.

In this embodiment having such a configuration, during normal lifting and lowering, the ladder main body 24 is folded so as to approach the side surface of the car main body 1 as shown in FIG.
That is, the pin 30 of the link guide 28 is the guide member 29.
Is fixed at the other end of the slit 29a of
The ladder body 24 is in a state of being closest to the side surface of the lower cab 4. As a result, the distance X between the ladder main body 24 and the side surface of the car 1 can be shortened, so that it is possible to prevent the ladder main body 24 from interfering with the elevation.

On the other hand, when the car 1 is stopped due to a failure or the like, the link guide 2 is used to escape from the lower car room 4.
8 of the pin 30 is moved along the slit 29a of the guide member 29. Then, the parallel link 27 pivots in the horizontal direction, the pin 30 moves to one end of the slit 29a, and the ladder main body 24 becomes substantially vertical to the side surface of the car as shown in FIG.

In this way, since the ladder main body 24 is horizontally translated by the parallel link 27 and stretched out, the escaper 22 exits from the side rescue port 6 of the lower car compartment 4 to the outside of the lower car compartment 4. As shown in FIG. 1B, between the side surface of the lower car room 4 and the ladder main body 24, the ladder main body 24 can be lifted with its back facing the side surface of the lower car room 4. For this reason, the escaped person 22 can climb the ladder more safely and at ease.

As shown in FIG. 6, a rescuer 41 standing on the ceiling of the upper cab 3 has a rope 43 with a safety belt 42 attached to the end thereof.
To make the escaper 22 wear this safety belt 42,
The rescuer 41 may rescue the rescuer 41 by pulling the rope 43 in accordance with the escaper 22.
Since it suffices to hang 3 between the side surface of the lower car chamber 4 and the ladder main body 24, it is possible to prevent the rope 43 from being caught by the protrusion in the hoistway. This allows the rescuer to rescue the escaped person 22 more safely and with peace of mind.

Next, another embodiment of the present invention will be described with reference to the drawings. In this embodiment, the same parts as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 7 is a view showing a ladder main body mounting mechanism of the car 1 of the double-deck elevator according to this embodiment. The difference from FIG. 2 is that the ladder main body 24 is attached to the side of the car by a pair of parallel links 26 and 27. The point is that the pair of pantograph-shaped links 51 and 52 are attached.

The pantograph-shaped links 51, 52 are specifically constructed by connecting four parallel links rotatably so as to be parallel to each other. Then, one of the nodes 53, 54 of the pantograph-shaped links 51, 52
Each of the two is horizontally rotatably attached to the car 1 and is rotatably attached to the cage 1. Nodes 55 and 56 facing the nodes are rotatably attached to the ends of the ladder body 24.

In this embodiment having such a structure, the ladder main body 24 is folded during normal lifting and lowering. That is, the two links of the pantograph-shaped links 51 and 52 are connected in series in the horizontal direction, and the other links are superposed on the lower side. The length when the pantograph-shaped links 51, 52 are extended is configured such that a person can climb between the side surface of the car 1 and the ladder body 24. Thus
As in the above-described embodiment, the overhanging ladder main body 2 can be lifted with the side surface of the car 1 as the back.

As a result, in addition to the same effect as the above embodiment, the distance between the ladder main body 24 and the side surface of the car 1 can be further shortened, and the car can be more compactly stored.

On the other hand, when the car 1 is stopped due to a failure or the like, when the car 1 is to be escaped from the lower car room 4, the ladder main body 24 is extended as shown in FIG. That is, the two links of the pantograph-shaped links 51 and 52 are connected vertically to the side surface of the car 1 in the horizontal direction, and the other links overlap the lower side. As a result, the ladder body 24 is extended in parallel with the side surface of the car. Therefore, the same effect as that of the above-described embodiment can be obtained.

Further, since the car 1 is placed on the back when entering the upper car room 3, it is easy for the rescuer to grab the body, so that it is easy to enter the upper car room 3 and fear is reduced.
It is easy to release one hand, and the rescuer can be rescued more safely and safely.

Further, as shown in FIG. 1, the ladder main body 24 is provided so as to extend to the upper portion of the upper cab chamber 3,
The escaped person can safely escape to the upper part of the upper car room 3 at once without using the side surface rescue port 5 of the upper car room 3 as a back with the car side surface of the upper car room 3 as a backrest.

Next, another embodiment of the present invention will be described with reference to the drawings. In this embodiment, the same parts as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 9 is a diagram showing a car 1 of a double-deck elevator according to the present embodiment. What is different from the above-mentioned embodiment is that the ladder main body 24 has a pair of parallel links 26, which are horizontally rotatable.
Instead of attaching to the side surface of the car at 27, a step 63 is provided at a point where it is attached by a pair of parallel links 61 and 62 which are rotatable in the vertical direction, and above the parallel link 62 at the lower end, and it is rotated in the vertical direction together with the parallel link 62. It is a point that can be moved.
The parallel links 61 and 62 are configured so that a length between the side surface of the car 1 and the ladder main body 24 is such that a person can climb up. In this way, it becomes possible to climb up with the ladder main body 2 extended like the above-mentioned embodiment with the side surface of the car 1 as the back. The parallel link 61 is provided in the upper cab 3, and the parallel link 62 is provided in the lower cab 4.

In this embodiment having such a structure, the ladder main body 24 is normally folded during the vertical movement. That is, in the state where the parallel links 61 and 62 are rotated upward, the ladder main body 24 approaches the car 1 and is stopped. As a result, the distance between the ladder main body 24 and the side surface of the car 1 can be shortened as in the above embodiment.

On the other hand, when the car 1 is stopped due to a failure or the like, when the car 1 is to be escaped from the lower car room 4, the ladder main body 24 is extended as shown in FIG. That is, the parallel link 6
1, 62 are rotated downward and fixed vertically to the side surface of the car 1 in the horizontal direction. As a result, the ladder body 24 is extended in parallel with the side surface of the car. For this reason,
It is possible to obtain the same effect as that of the above embodiment.

Further, the step 63 is connected to the parallel link 62 at the lower end.
In order to attach the ladder body 24, the ladder body 24 is simply extended, and the ladder body 24 is rotated together with the parallel link 62 to automatically form the bottom surface between the ladder body 24 and the side surface of the lower cab 4. As a result, it is possible to save the trouble of overhanging the step 63, so that quick relief can be achieved.

In this embodiment, the parallel link 6
The above description has been given for the case where the upper and lower cabs 3 and 4 are provided one by one, but the invention is not necessarily limited to this, and a plurality of parallel links are provided in the upper and lower cabs 3 and 4, respectively. May be

Next, another embodiment of the present invention will be described with reference to the drawings. In this embodiment, the same parts as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 11 is a view showing a car 1 of a double-deck elevator according to this embodiment. What is different from the above embodiment is that the upper end of the ladder body 24 is made of a cloth or the like formed in the width of the ladder body 24. One end of a front blindfold roll member 71 formed by winding a strip is attached, and a strip formed of a cloth or the like formed on both sides of the upper end of the ladder main body 24 to the width of the extension of the ladder support portion. This is a point in which one end of the side blindfold roll members 72 and 73 formed by winding is attached along the length direction of the ladder support portion.

The lengths of the strips of the front blindfold roll member 71 and the side blindfold roll members 72, 73 are at least longer than the length of the ladder main body 24. In the present embodiment having such a configuration, during normal lifting and lowering, the front blindfold roll member 71 and the side blindfold roll members 72, 73 are
It is fixed in a state of being wound on the upper portion of the ladder main body 24. As a result, it is possible to prevent the roll members 71, 72, 73 from interfering with the elevation of the car 1.

On the other hand, when the car 1 is stopped due to a failure or the like, when the car 1 is to be escaped from the lower car room 4, the ladder main body 24 is extended from the car 1 as shown in FIG. At this time, the other end of each of the blindfold roll members 71, 72, 73 is pulled by a string or the like, or the rescuer in the upper cab 3 unrolls and hangs the roll vertically downward. Then, the front part of the ladder main body 24 and the side surface of the car 1 and the ladder main body 2
The side part between 4 and each of the blindfold roll members 71, 72, 7
Blindfolded by 3 strips. This makes it difficult for an escaper from the lower cab 4 to see the surroundings when climbing up the ladder body 24, and has the effect of reducing the fear of the escaper 22.

[0050]

As described above in detail, according to the present invention, since the ladder main body is configured to be foldable in the storage position close to the outer surface of the car, the ladder main body can be folded in the storage position when moving up and down. Since it can be placed, it can be prevented from interfering with the lifting operation of the car.

Further, when escaping from the lower car room, it is possible to extend the ladder main body from the storage position close to the outer surface of the car by a distance such that a person can climb between the outer surface of the car and the main body of the ladder. This allows the escaper to climb up the ladder body with the outer surface of the car as the backrest.

As a result, the escaped person can climb the ladder more safely and with peace of mind. Moreover, even when rescued from the upper cab, the rescuer can easily grasp the body, and can rescue the escaped person more safely and with peace of mind.

Further, by hanging the strip-shaped member of each blindfold roll member downward from the upper part of the ladder main body, this strip-shaped member serves as a blindfold for the front and side surfaces of the ladder main body. This makes it difficult for an escaper from the lower cab to see the surroundings when climbing up the ladder main body, and has the effect of reducing the fear of the escaper.
