Description

[Detailed Description of the Invention] This patent relates to a device for evacuation in the event of a fire or the like in a high-rise building, hotel, condominium, etc.

Currently, construction of PIR buildings is active nationwide, and the number of high-rise buildings is increasing, but the evacuation method remains the same as before.
Various equipment and tools have been tried, such as emergency stairs, rope ladders, ladders, evacuation balls, rescue pull-up bags, and slow descent devices, but all of them have problems with safety, speed, and economy, and evacuation It could not be said that the equipment or tools were sufficient.

Especially recently, when considering the casualties caused by smoke pollution caused by new building materials, the first thing to consider is escaping to the outdoors (outside the window).

The present device was invented with the aim of achieving the minimum necessary and maximum effect in order to eliminate those drawbacks, but the present patent applicant's previous application (Japanese Patent Application No. 53-157907)
The control function, which was an important issue for the "lowering coil" related to this, could be added here.

To explain this with reference to drawings, it is a device mainly consisting of a coil spring as shown in FIGS. 1 to 4, which is made of steel that can withstand considerable weight and friction.

A coil of appropriate length is folded in the center, and a two-turn spiral is provided on the folded part.The upper and lower coils are overlapped, and the end of the lower coil is tied at a certain angle. The upper and lower ends of the coil are stretched downward and a spiral is added to the tip, and the end of the upper coil is similarly stretched upward to form a handle spiral. This usage method is to fix it to the upper part of a building and hang it outdoors! + (nylon rope, etc.) 7ciK5 As shown in the diagram,
When the upper and lower fills are wound together in the same spiral direction as the coil, the rope will be passed through both the upper and lower coils. Therefore, a suitable rope or string (which can also be attached by wrapping it as described above) is passed through the lower end handle coil 4 and tied to the body, and the upper handle coil 5 is tied to the body.
The robot descends in a hanging position as shown in Figure 6 while operating the robot.

The feature of this project is that the device can be quickly and completely attached by winding the rope several times even from the middle of the rope, so it can be used to escape from any floor of the building, and there is no fear of it coming off, so it can be used by men and women of all ages. It must be easy to use.

After installation, if you push the upper coil upwards as shown in Figure 7, the common hole of the upper and lower coils will be pinched or separated, the frictional resistance of the rope passing through it will become thicker, and the descending speed will be slower.
Eventually it will stop.

Alternatively, if it is gradually lowered as shown in Figure 8, the common hole will widen, the frictional resistance will decrease, and the speed of descent due to body weight will increase.

Also, since the arm 6 is extended from the end of the lower coil 1,
The degree of bending of the rope changes depending on the JMfk of the rope under the coil after attachment and the weight of the descending person. In other words, for a person who is relatively light in weight, the tail part 3 of the coil is pulled downward and at the same time the force that flips the coil 4 upward is exerted, and the bending process becomes gentle and there is less resistance. The opposite is true for heavier people, and the resistance increases.

Furthermore, even if you accidentally skip the first loop when attaching the rope to this device, there is no big difference in the effect, and although it is correct to attach the rope around your body to the handle coil 4, you may accidentally wrap it around the coil 5. Even if it is attached, there is almost no change in the effect of adjusting the descending speed as the instrument simply reverses, and the advantage is that it allows for safe descent even when in a state of panic.

The device of this invention combines several features as described above and exhibits a synergistic effect, but its structure is simple and mass production is possible, and it does not get entangled in ropes. Since it is a light device that can be used to slide down and down, there is no need for large facility costs such as emergency stairs, and since it descends vertically, it requires little space.

By adjusting the way the coil is wound, it can be lowered at a constant speed, making it extremely convenient for transporting luggage and cleaning items from upper floors during normal times, and it can also be used in place of a pulley. can. In addition, it is possible to stop the rope for a long time by clipping the part 8 of the rope in Figure 7 or by inserting a support that extends the upper and lower coils from each other. and cleaning outside windows,
It can also be used for painting work.

In addition, if you store the rope normally and let it hang outside in case of an emergency, it will help prevent illegal entry into hotels and condominiums using emergency stairs or balls, and will not damage the building's appearance. If you always manage the rope, its installation location, and the equipment involved, you will not have to panic in an emergency.

However, since the use of this device involves escaping from a high-rise building in an emergency, it is natural to feel a considerable amount of fear. There is no doubt that the feeling will go away.

In any case, if you think about jumping down from a height of a building with your bare hands in the event of a disaster, it is clear to you how reassuring the proposed equipment and a single rope can be. Additionally, since this device is made entirely of steel with high elasticity, it can be used in a variety of ways in daily life, such as with a hanging bracket for equipment for building physical strength (expanders, grips, etc.). It's coming. In short, it is important to keep it familiar and close at all times, and ready to use it at any time.

Claims (1)

[Claims] Arms of a certain angle and length are attached to both ends of the coil spring, and the central part of the coil is bent and stacked one on top of the other, and by adjusting the amount of overlap, the lobe that passes through the inside of the coil is controlled and lowered. A descending device with adjustable speed.
