What it for

According to the present fire-safety suggestions , once the people are trapped in storied-building fires , 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 building as soon as possible and rescue themselves successfully without waiting , it 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   

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 the 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 strength 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 avoided in the special panic of escape .

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