What it for

According to the present fire-safety suggestion , once people are trapped in storied-building fire , first they must try to keep themselves safe , then wait for firefighters` rescue . However , lots of facts tell us that sometimes death always comes before rescue , that`s why there were always so many dead in storied-building fire . So how to help the people trapped to escape from the burning buildings as soon as possible and rescue themselves successfully without waiting , is the best way to reduce the dead in storied-building fires and it is just the only aim of my invention as well .

How it made


front-look fig

right-look fig

up-down-look fig

A-A cut-look fig

B-B cut-look fig
1 steel-rope , 2 hook ,3 axle ,3-1 brake-drum ,4 main-frame , 4-1 axle-holders ,4-2 axletree-for-brakes , 4-3 axletree-for-wheel ,5 rope-case ,6 screw nut ,7 brakes ,8 spring ,9 long-shape- wheel ,9-1 wheel base ,10 control-handle ,11 assistant-handle ,12 rope-leader ,13 cricle-for-belt ,14 balance-handle

According to the figs above , the axle(3) goes through the two axle-holders(4-1)of the main-frame(4) and goes through the rope-case(5) which is between the two axle-holders(4-1) , then it is fixed by the screw nut(6) and the axle(3) can turn around freely in the two axle-holders(4-1) . The rope-case(5) is fixed firmly together with the axle(3) . On the one end of the axle(3) is a brake-drum(3-1) and there are two brakes(7) around it . The brakes(7) are hinged with the main-frame(4) by two axletree-for-brake(4-2) , and other ends of the brakes(7) is fastened by the spring(8) which offers the force for braking . Between the two brakes(7) , there is a long-shape-wheel(9) which hinged with the main-frame(4) by the axletree-for-wheel(4-3) . The long-shape-wheel(9) can set the brake-drum(3-1) free suitably from the brakes(7) by its` turning . The long-shape-wheel(9) is based on the wheel-base(9-1) and a control-handle(10) is setted on the wheel-base(9-1) and there is an assistant handle(11) setted for cooperating with the control-handle(10) .The control-handle(10) is folding and the assistant handle(11) can be stretched out and drawn back. The cricle-for-belt(13) is hinged with the main-frame(4) , the rope-leader(12) is hinged with the main-frame(4) . One end of the steel-rope(1) is the hook(2) , then another end of the steel-rope(1) goes through a rope-leader-hole of the rope-leader(12) , then the steel-rope(1) will be fixed with the rope-case(5) and twines about the rope-csae(5) . The balance-handle(14) is hinged with the main-frame(4) and the balance-handle(14) is folding .


How and when to use

Once people are trapped in the storied-building fire , the instruments can be used at once .

一、 Fasten your easy-safebelt quickly .

二、 Take out the self-rescue instruments and get your safebelt linked with the instruments correctly and firmly .

三、 Take the instruments up by its` rope-leader(12) and look for an outlet(such as windows) for escape , try to avoid smoke and fire in your down-way .

四、 Put the hook(2) onto a setted-cricle on the wall or fix it to other stuff that can bears your weight .

五、 Open the balance-handle(14) and the control-handle(10) , pull out the assistant-handle(11) , then one hand grasps the balance-handle(14) , another hand grasps the control-handle(10) and the assistant-handle(11) .

六、 Get yourself out of the building and start your self-rescue .

七、 The instruments does not work without a control force and the control force is about 5N~25N,according to your different strengh of control force, you can get different speed of going-down . the force is bigger ,the speed is higher , as soon as the control force is gone , the instruments will brake itself automatically at once even if you have a weight of 150kg . In this way , accidents can be avoidedin the special panic of escape.

八、 Get your safebelt separated from the instruments as soon as you reach the ground and leave away quickly .

Major design parameters

Design specification : two basic types and some other types

Package size (cm ) :15 x 10 x 10~20 x 13 x 15

Advantages


1、 It`s safe, easy to use and quick escape.
2、 It`s low-cost , low-weight , little size and easy-made.
3、 It`s self-brake and controllable through all escape . No accidents .
4、 It`s applicable in all complex building fires , it`s easy for storage and maintenanceless all life .
5、 One man can operate this device independently without any help of others .
6、 People won`t obstruct each other when they are escaping at the same time . In other word , when you are escaping , you won`t obstruct any others and you won`t be obstructed by any others either .
7、 Fire escape should disperse so that all the people trapped can get out of the burning buildings at the same time . Fire rescue should concentrate so that the firefighters can save as many as possible at one time . As fire escape devices , one device for one man .

POSTSCRIPT




An open letter to the firefighting experts and firefighting professionals

Hello ! every firefighting expert and firefighting professional . I am a Chinese inventor ,as a nongovernmental firefighting-tech worker ,I ask you two questions about selfrescue in building fires .

First , when people are trapped in a building fire , is it necessary for them to take actions of selfrescue ? and should be there any professional selfrescue-instruments provided? Secondly ,if there should be some kinds of professional selfrescue-instruments provided, then what elements should the selfrescue-instruments have ?

No offence, but to be frank , any firefighting experts who have never thought about the two questions above should be negligent .All the firefighting experts have their duty to give people more and more safety in their lives.



Perhaps someone will retort ：“ there were many kinds of professional self-rescue gears earlily , such as rope-escape systems , escape ladders and so on . how can you say there are not professional selfrescue instruments ? and all these gears are perfect enough . People don`t get these gears for fire escape just because they do not care about their own lives .
”But have you ever thought why the rope-escape systems and escape ladders can`t be popularized as well as smoke-alerts and fire extinguishers ? Because if you take escape ladders as your selfrescue gears ,how can you be sure that you will never hurt the people who are also escaping at the same time below your floors ? people below your floors maybe hurted when you spread down your ladders .Another question ,you will never be able to stop the people below your floors who will take your ladders , when there are too many people on your ladders ,your ladders will be broken ………… All in one word ,there are too many un-definitive and uncontrolled things in using them as selfrescue gears . As to the rope-escape system , it is just a professional gear for those professionals (such as firefighters , climbers ,etc .) , the common people can`t use it without training . Besides ,if there are ten or more rope-escape systems in one place ( people may escape at the same time from every floors of the buildings), will the ropes be knotted or will they twine together ?




Surely, if you think it is impossible that there will be any kinds of feasible selfrescue instrumrnts for the people trapped in building fires , you would never thought about how to solve this problem either . But how do you conclude that there will never be any kinds of feasible selfrescue instruments ? There is a necessity ,there will be an invention to it , necessity is the mother of invention . On the other hand ,if you are trying to work out a solution to this selfrescue-problem , you should know clearly that what elements the solution should have , it is very important ,because it is the direction of your research work . Just like this , if you say you are looking for something ,but you don`t know what the things you are looking for would be like , then you will never find it !and you will miss it as well even if it is just in front of your eyes .

Drawing is the best self-vindication of an invention .As the drawings of a general machine device , there is not any difficulty in reading it , because drawing is the professional communication language of technician .I would never want to deceive , I just show my invention to the world and then let the world judge it .
