Description

[Detailed Description of the Invention] With the increase in the number of high-rise buildings, evacuation during disasters has become a problem. Evacuation in the event of a fire is particularly important, and for this reason various maneuvers,
Methods have been developed and implemented, but at present they are highly safe, do not take up much space, and are economical.

Emergency stairs, a single thick life net, an escape net, and a rope ladder are all devices that evacuees can use to escape to the ground or a safe place using their own knives. It would be impossible for people with poor physical strength to descend from high places with their own knives and escape.

The present invention solves the problems of existing evacuation equipment, and its main components include a looped life net and a pulley that rotates the rope. In other words, a looped rope that reaches the ground is hung from a pulley, and when a person attaches to one side of the rope, the rope descends and the person reaches the ground without any special force; Rising again through the seven wheels, the rope circulates continuously as one piece, facilitating free movement from heights, which is mIH as shown in the figure.

(1) is a life net that is a loop around the main body.

(2) is a case of a pulley that supports the rope and rotates the rope.This case is fixed to the building with a pulley fixing device (5).When an evacuee attaches to M\(1), the rope rotates through the pulley. Therefore, a large number of people (3) can safely and quickly reach the ground (4) from high places one after another.

Item 2 of the patent request is to provide a braking operation to the pulley to prevent the rope from falling suddenly due to the weight of many people when holding and rotating the circulation type lifesaving device. This shows that

An example will be explained with the help of a diagram.

The pulley is built into the case, and the case (2) has a pulley fixing device (5
) to secure it to the structure. Inside Kenneth there is an upper pulley (6
), a lower pulley (7) and a brake pulley that are involved in the rotation of the net. One of the brake pulleys (8) is fixed and the other one is movable, and the shafts of both pulleys are connected by a spring (10).6 When a strong force is applied to the rope (1) and it suddenly descends, the rope A movable braking pulley under tension is brought into contact with a fixed pulley, and the braking function caused by the opposing rotations of the seven cars is applied to the rope.

If this circulating lifeline is installed at a high place such as a super high gill, and it is thought that the line will likely descend quickly, install a pulley on the upper pulley (6) and then the lower pulley (7). Equipped with a braking system that utilizes the centrifugal force of rotation.

As a measure to prevent danger to evacuees due to the rapid descent of the rope, in addition to braking the pulley, if the rope is rising at the same speed on the opposite side, the rotation speed of the rope will be reduced and safety will be maintained. .

The item of claim 3 shows the structure of the rope when the above-mentioned circulating life net is used.

An example thereof will be explained with reference to the drawings.

One is a thick main lobe (11) that forms the main body of the lifeline.A slightly longer length of the zarobe (12) is attached to this, and the two lobes are connected at the binding part (13). The space between the ropes (14) is used by evacuees to secure themselves by placing their feet or arms in the space when evacuating, and is essential in a circulating life net.

As explained above, the present invention is extremely safe and economical. With the increase in the number of high-rise buildings, safe evacuation during disasters has become a social issue, and it is imperative that the present invention be promptly implemented to save lives.

[Brief explanation of the drawing]

Figure 1 is a diagram showing the situation of evacuating from a high place using a circulation type life net. FIG. 2 is a plan view showing the inside of the pulley case. FIG. 3 is a plan view showing the aspect of the lifeline. (1) is a lifeline (2) is a pulley case (3) is an evacuee (4) is the ground (5) is a pulley fixture (6) is an upper pulley (7) is a lower pulley (8) is a brake pulley (9) ) is the direction of rotation (10
) is the spring (11) is the main lobe (12) is the sub lobe (13) is the binding part (14)

Claims (1)

[Claims] 1. A maneuver in which a looped rope is rotated through a pulley fixed at a high place, and people and objects are continuously lowered by the rotation of the rope while holding the rope. 2. When a part of the looped rope is pulled with strong force, a braking force is automatically applied to change the circulation speed of the rope. 3. A pulley consists of multiple ropes of different thickness and length, and A rope that has binding parts at the ends and forms a single ring as a whole.
