BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail based on specific embodiments shown in the accompanying drawings.

FIG. 1 shows an example in which an emergency escape ladder is attached to the outer wall surface of a building. In the case of this embodiment, three emergency escape ladder units 1 are connected and stored.

Each of the emergency escape ladder units 1 is shown in detail in FIG. The handrails 2 made of metal are arranged in parallel in the vertical direction so that both feet of a person can be placed, and the metal footsteps 3 are made parallel between the two handrails 2 at the height at which the foot of the person rises. Place and fix both ends. A stopper 4 is projected outward from the upper portion of the handrail 2, and a guide 5 made of a plate having an L-shaped cross section is fixed to the lower portion of the handrail 2 so that it can be guided when other units 1 are stacked. The guide 5 also engages the stopper 4 of the other unit 1 so that the other unit 1 can be suspended.

If the handrail 2 and the foot 3 are made of an extruded aluminum material, they are lightweight and have sufficient strength.

In the case of FIG. 1, three units 1 are stacked, and in each case, the lower unit 1 can be suspended by the guide 5.

The bracket 6 is attached to the outer wall surface of the anchor bolt 5
The innermost unit 1 (unit 1 close to the outer wall surface) is fixed at 2, and the stopper 4 on the upper part is pivotally attached to the bracket 6. Further, the issuing lever 7 is attached to the bracket 6 with a pin 51.
Is rotatably pivoted around, and the engaging lever 8 is projected from the intermediate portion thereof to support the foot 3 of the outermost unit 1 at the tip of the engaging lever 8. Here, the issuing lever 8
When the pin 51 is rotated rightward, the support of the foot 3 of the engagement lever 8 is released, and the unit 1 is lowered as shown by the broken line in the figure. The lower end of the lowermost unit 1 is positioned above the head of a person on the ground to consider the safety of a person on the ground.

This emergency escape ladder is usually covered with a decorative cover 9 to maintain the scenery.

When an emergency such as a fire occurs, a person opens the decorative cover 9 through the window 10 and rotates the supply lever 7 to lower the unit 1 to use the emergency escape ladder.

This emergency escape ladder is easy to operate even in an emergency, the installation location can be easily found, and the foot 3 is made of metal and can be used stably and safely, and has durability that allows repeated use. is there.

Another embodiment is shown in FIGS. 3, 4 and 5.

In FIGS. 3, 4 and 5, the handrails 12, 2 are shown.
An example using a rope, a wire, or a chain is shown as 2, 32, and the handrails 12 and 12, the handrails 22 and 22, and the handrails 32 and 32 are fixed to each other by leaving both ends of the metal foot 3 at predetermined intervals.

In FIG. 3, stoppers 4 are fixed to the upper ends of the handrails 12 outwardly. Further, a guide 15 made of extruded shape is fixed to the lower end of the handrail 12. The unit 11 shown in FIG. 3 is also used similarly to the unit 1 shown in FIG. Unlike the unit 1 of FIG. 2, the handrail 12 of the unit 11 of FIG. 3 is flexible.

In FIG. 4, joints 33 having insertion holes 23 are fixed to the upper and lower ends of the handrail 22 and used in the same manner as the unit 1 shown in FIG. Unit 21 of FIG.
The handrail 22 is different from the unit 1 of FIG. 2 in that the handrail 22 has flexibility.

In FIG. 5, a metal cylinder 33 is fixed to the lower end of the handrail 32. The unit 31 shown in FIG.
Unlike the units 1, 11, and 21 shown in FIGS. 3 and 4, the winding method is used.

The above has described the wall-equipped emergency escape ladder unit attached to the outer wall surface. Next, the eaves-equipped emergency escape ladder unit attached to the eaves will be described with reference to FIGS. 6 and 7. Reference numeral 43 is an eave roof, reference numeral 44 is an eave frame, and reference numeral 45 is an eave ceiling.

In FIG. 6, the unit 41 is folded and accommodated in the eaves 40.

As shown in FIG. 7, in the unit 41, metal handrails 42 are arranged in parallel in the vertical direction so that both feet of a person can be placed, and a human foot is placed between the two handrails 42. The metal steps 3 are arranged in parallel to the rising height, and both ends thereof are fixed.

A plurality of units 41 (three in FIG. 6)
Is connected by interposing hinges 46 at the upper and lower ends,
Fold it up and store it in the eaves frame 44.
The upper part of the above is rotatably provided on the suspension rod 47 installed on the eaves frame 44. A support member (not shown) slidably provided on the eaves frame 44.
The unit 41 in the lowermost stage is placed on the above.

When an emergency such as a fire occurs, a person pulls out the supporting member from the window 48 to release the folded state of the unit 41, and the ladder for emergency escape is used by lowering the unit 41.

This emergency evacuation ladder is easy to operate even in an emergency, the installation location can be easily found, and the stepper is made of metal so that it can be used stably and safely, and can be used repeatedly and has durability. .

[0032]

As described above, according to the present invention, the metal handrails are arranged at a predetermined interval in parallel and are arranged in parallel, and a plurality of metal footsteps are formed by connecting the handrails at a predetermined interval in parallel. This is an emergency escape ladder unit, so it is easy to operate, the installation location is easy to know and it can be used immediately, and it is safe and durable because it can be used stably, and it can be used repeatedly.

The present invention is easy to install and can be installed in an existing building in a short time.
