Description

Public safety ladder and its operating method

The present invention relates to a public safety ladder for emergency escape and its operation method, an emergency escape public safety ladder and its operation method to enable a quick and safe evacuation downstairs with a simple operation when a fire and disaster situation occurs. It is about.

Generally, in case of a fire or disaster situation in a high-rise building such as an apartment, a shopping mall, or an office, a top-down emergency escape device is used, and it is possible to escape to the floor or the ground by descending ladders on the floor such as a balcony. Doing.

Such a top-down emergency escape device is disclosed in Korean Patent Registration No. 10-1105685.

“Fire evacuation descending mechanism” disclosed in Korean Patent No. 10-1105685 is an antenna bridge that maintains a constant angle with the ground while being drawn out at its own weight; A lowering member installed on the antenna leg to assist the lowering of the user; Locking means installed at the bottom of the frame to hang the end of the antenna leg, and for restraining arbitrary fall of the antenna leg; And folding means installed in the frame, connected to the antenna legs, and folding the drawn antenna legs to a minimum length that can be accommodated in the frame.

Not only can it be operated alone but also has the effect of evacuating a large number of people quickly, but it is a hassle to check if there is a person on the lower floor and lower the antenna bridge, and there is a person on the lower floor. Lowering the antenna legs without checking if there is a risk of secondary safety accidents.

In view of this, the “escape escape device” disclosed in Korean Patent No. 10-1615728 discloses that a life container is moved indoors by a first actuator out of an outer wall of a building, and a safety slide is automatically moved downstairs by a second actuator. It is developed to disclose a configuration for connecting each floor of the building from the outside.

It is easy to evacuate and escape from the upper floor to the lower floor by using the safe slide, anyone, young and old, there is a problem that can cause malfunction of the life container and the safety slide when the problem of the actuator caused by the fire.

Hereinafter, an embodiment of the present invention as described above will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the public safety ladder 1000 of the present invention has a frame 100 having a space formed on a ceiling surface of a floor, and an emergency escape door that is rotatably installed on one side of the frame 100. 200 and the frame 100 is provided to include a rotatable ladder 300 that is rotatable and installed in the height direction of the floor.

In addition, as shown in Figure 2, the public safety ladder 1000 of the present invention is a locking member 120 is formed to be able to move up and down on the rear of the ladder 300 extendable, and one side of the lower locking member 120 Is connected to the joint portion 121 of the rotatable and the other side is formed on the holding member 130 and the extendable ladder 300 is fitted to the extendable ladder 300, and one side is rotated with the extendable ladder 300 It may further include a damper 150 that is possibly connected.

For example, as illustrated in FIG. 2, the extendable ladder 300 may be rotatably connected to the bracket 321 at one lower side of the frame 100. In addition, the extendable ladder 300 may be configured to slide the first ladder 310 and the second ladder 320. In this case, as shown in FIG. 2 or 4, the other side of the holding member 130 fitted with the extendable ladder 300 may be fitted with the first side stand 322 of the second ladder 320. The hooks 141a, 141b, and 141c may be formed on the inner wall facing the rear side of the extendable ladder 300 and close to the inner wall and surround the locking member 120.

Therefore, as shown in FIG. 2 or FIG. 3, when the emergency exit door 200 is opened, the emergency exit door 200 is pressed behind the locking member 120. Then, the locking member 120 is moved downward, and the holding member 130 is caught by the first ring 140 to be separated from the first ladder 322 extending as the holding member 130 moves upward.

2 or 5, one side of the damper 150 that is rotatably connected to the extendable ladder 300 may be rotatably connected to the second side stand 323 of the second ladder 320. . On the other hand, the other side of the damper 150 may be rotatably installed on the inner wall facing the rear of the extendable ladder 300 adjacently.

Therefore, as shown in FIG. 2, when the extendable ladder second rail stand 323 and the holding member 130 are separated, the damper 150 connected to the extendable ladder 300 is unfolded, and the extendable ladder 300 is unfolded.

In addition, as shown in Figure 3, the locking member 120 may further include a plurality of sliding rails (142a, 142b) for guiding the sliding movement. As shown in FIG. 2 or 3, a plurality of sliding rails 142a and 142b are disposed between the layer inner wall and the locking member 120 facing the rear surface of the extendable ladder 300 and the locking member 120. Can be fixed to each).

In addition, as shown in Figure 2 or 3, there may be a spring stop 122 in the locking member 120 body. And there may be a spring 123 surrounding the locking member 120. And the spring 123 may be formed between the ring 141b and the ring 141c surrounding the locking member 120. Spring stops 122a and 122b may be formed below and above the spring 123 and between the rings 141b and 141c, respectively. At this time, the spring stop 122a on the spring 123 is fixed to the locking member 120, and may not be fixed to the ring 141b. And the spring stop 122b under the spring 123 is not fixed to the locking member 120, and may be fixed or fitted with the ring 141c.

Therefore, the spring 123, which is relaxed as shown in FIG. 2 (a), is stopped by the spring stop 122a which is fixed to the locking member 120 when the locking member 120 is lowered as shown in FIG. The spring 123 may be retracted. When the emergency exit door 200 is closed, the contracted spring 123 is relaxed, and the locking member 120 may rise to return to the position before opening the emergency exit door 200.

As shown in FIG. 6, a wheel 301 may be further provided at the lower end of the extendable ladder 300. In addition, the rail 21 may be further provided at the bottom of the floor along the trajectory of the lower end of the ladder 300 that can be extended. This has the effect of allowing the extensible ladder to unfold more quickly.

In addition, as shown in FIG. 6, a block 22 may be further provided at a trailing end of the lower end of the extendable ladder 300. For example, the block 22 may be located at the end of the rail 21. Thus, after the extensible ladder 300 is unfolded, the extensible ladder 300 can be stopped more stably by the block 22 on the floor bottom surface 20.

Also, as shown in FIG. 6, in order to prevent the extendable ladder 300 unfolded by the damper 150 from moving backward, a part is on a trajectory under the extendable ladder 300, and a part of the extendable ladder 300 is extended. A rotatable rotary block 23 formed below the locus at the bottom may be further provided.

For example, as shown in FIG. 6 or 7, the rotating block 23 may be formed on the rail 21. The rotary block 23 may pass through the rotary block 23 on the bottom surface of the rail 21 when the extendable ladder 300 is unfolded. At this time, the rotary block 23 may rotate in the direction in which the wheel 301 proceeds. Then, the rotary block 23 that was on the bottom surface of the rail 21 enters the bottom surface of the rail 21 toward the wheel 21 in the traveling direction. And the rotary block 23 that was under the bottom of the rail 21 is raised above the bottom of the rail 21, at this time the rotary block 23 raised above the bottom is formed behind the wheel 301 is damper 150 Extendable ladder 300 unfolded by) can be prevented from moving backward.

On the other hand, as shown in Figure 8, the operation method of the public safety ladder 1000 of the present invention, while the emergency escape door 200 is opened (S100), one side of the emergency escape door 200 is the locking member 120 down It may include a step S110. After that, when the locking member 120 moves downward, the holding member 130 holding the extendable ladder 300 moves upward, and the extendable ladder 300 and the holding member 130 are separated (S200). It may include. And it may include the step (S300) that the damper 150 connected to the extendable ladder 300 is unfolded. And it may include a step (S400) that the extendable ladder 300 is unfolded. Additionally, the extensible ladder 300 may further comprise the step of being stopped by the block 22 at the floor bottom 20.
