A conventional safety belt used in building construction etc. has a structure as shown in Fig. 1. That is,
It is composed of a belt main body a and a lifeline b connected to the belt main body a. At the end of the lifeline b, a hook d (in the illustrated case, a hook to be hung on a temporary pipe c, etc.) is provided. When in use, the belt main body a is attached to the body, and the hook d is hooked to a hook near the work place. By doing this, even if the worker loses his footing from the scaffolding, he will be suspended by the lifeline b and will be prevented from falling. Lifeline b is designed to be long enough to allow workers to work freely. Therefore, when lifeline b is not in use, it must be dragged while walking, so it is usually folded in two. That is, in the illustrated case, a hook is hung on the band body a.

しかし乍ら、上記の如く2つ折にしたとしても

However, even if it is folded in two as described above, the lifeline B is hanging near the feet, which is not only a nuisance for walking, but also has many protruding parts such as steel frame structures or reinforced steel structures. At work sites, this was extremely dangerous as there was a risk that the loop formed by folding in two would get caught in the protruding part and the body would be scooped up and fall to the lower floor.

In the figure, 1 is the main body of the belt, 2 is a lifeline connected to the main body 1 of the belt, and the end thereof is a hook (in this case, a hook to be hung on a temporary pipe 3, etc.)
It is equipped with 4. As shown in FIG. 3, the lifeline 2 is composed of a core material 5 made of chemical fiber (for example, nylon) and a covering material 6 made of vinyl resin that is permanently treated into a coil shape. ing. The core material 5 is designed to have sufficient strength to withstand the load when a worker is suddenly suspended. Therefore, this lifeline 2 is normally reduced into a coiled shape (when the hook 4 is not used) due to the action of the sheathing material 6, and when working with the hook 4 hooked, Since the coil portion 7 extends until the entire coil portion 7 is unwound, a free posture can be taken within that length range. (The total length when extended is the same as the total length of the conventional lifeline.) As mentioned above, it is usually reduced into a coiled shape, so if you fold it in half, it will fit around your waist. Become. For this reason, it is not cumbersome when walking, and there is no chance of getting caught on the protruding parts.

As described above, in this embodiment, the lifeline 2 is formed by covering the core material 5 made of chemical fiber with the covering material 6 made of vinyl resin which has been permanently treated into a coil shape. The core material 5 made of chemical fiber has flexibility, and even if the core material 5 is coiled, it tends to relax into a non-tensioned state when the covering material 6 is removed. . In addition, the outer side of the core material 5 made of chemical fibers and the inner surface of the covering material 6 made of vinyl resin are in close contact with each other, and the frictional resistance between them is large due to their materials.
When the lifeline 2 is pulled, the core material 5 is elastically deformed and twisted, and has the property of trying to eliminate this twisting. Furthermore, since the covering material 6 has been permanently treated to form a coil, it has the property of becoming coiled. Therefore, the lifeline 2 is affected by the force of the core material 5 that tends to relax into a non-tensioned state, the elastic force of the core material 5,
This is a state in which the force of the sheathing material 6 to form a coil shape and the frictional resistance between the core material 5 and the sheathing material 6 are balanced.
Therefore, by pulling the core material 5 in the direction in which the core material 5 tends to relax into a non-tensioned state, the core material 5, the covering material 6,
Since the balance of frictional resistance between the core material 5 and the covering material 6 is disrupted, the lifeline 2 can be easily extended with a small force due to the force of the core material 5 trying to relax into a non-tensioned state. In addition, when the lifeline 2 is stretched out, the core material 5, the sheathing material 6, the elastic force of the core material 5, and the frictional resistance between the core material 5 and the sheathing material 6 are in equilibrium, so the lifeline 2 is held as it is. be able to. Furthermore, the covering material 6
By applying force in the direction in which the core material 5 and the sheathing material 6 tend to become coiled, the balance of frictional resistance between the core material 5, the sheathing material 6, and the core material 5 and the sheathing material 6 is disrupted, causing the elastic force of the core material 5 and the coiling of the sheathing material 6 to Lifeline 2 can be easily retracted by the force of trying to shape.

In summary, in the safety belt according to this invention, the lifeline connected to the main body of the belt is composed of a core material made of chemical fiber and a resin covering material that is permanently processed into a coil shape. Therefore, as mentioned in the embodiment, due to the expandable function of the covering material, the lifeline is reduced to a coil shape and placed around the waist when walking while wearing the covering, which has the practical benefit of eliminating the conventional problems. .
