Description

Safety belt with function of luminescence sign

This design must be worn by police officers, firefighters, 119 rescue workers, security patrol officers, road sweepers, and workers at various industrial sites, and it is also necessary to wear various types of travelers for safety. The present invention relates to a belt, and more particularly, to a seat belt having an improved luminescent label function for easy identification as a label using luminescence along with an original function for easily carrying various tools required for work or travel.

In general, a seat belt is a simple waistband that has various storage bags and metal rings attached to it, or a belt that is worn over the chest and back of the wearer's body. It is easy to bring necessary tools to wear, and it is variously configured to attach or connect various safety devices such as hanging rope to prevent fall according to each work site.

Such a seat belt is a luminous sign that is easily visible to vehicle drivers at night for the safety of vehicles such as traffic policemen, firefighters, 119 rescue workers, road sweepers, etc. You need to have a function. If several teams, such as firefighters and rescue workers, are to work in unison according to the command, it is necessary to have a mutually recognizable marking function for a good command control. On the other hand, travelers such as fishing or mountaineering need to wear easy-to-identify seat belts for quick rescue during distress, especially at night.

For example, in the related art related to the seat belt, US Patent 3,153,745 embeds an electric light emitting device panel in the belt and the belt of the seat belt and covers it with a transparent material, and drives it to emit light with a separate power pack to implement a light emitting label function. do.

In addition, the Republic of Korea Utility Model Registration No. 20-0188083 eliminates the hassle of having to wear safety belts integrally with rescue clothing or fire fighting suits, and at the shoulders of safety belts, especially on the shoulders, It provides a light emitting function of simple structure with a luminous member attached.

As described above, the safety of night activities has been achieved by using an electric light emitting device panel or a luminous member.

By using the above-described electric light emitting device panel or luminous member, it is possible to make the vehicle driver's eyes stand out more, so that it is possible to ensure the safety of night activities and to mutually identify each other, so that command control is possible. However, this conventional technique has the following problems.

That is, the above-described electric light emitting panel can perform the light emitting label function while the power is stably supplied, but the power consumption is large, and when the power is consumed, it cannot be driven at all, and there is a high risk of damage during field activities. In addition, it is preferable to make the front of the seat belt to be more visible, and the electric light emitting panel is expensive, so it is expensive to cover the front of the seat belt with this.

On the other hand, the luminous member is usually using a phosphor or a fluorescent material. Phosphors emit light at night after accumulating light energy during the day, using the principle of emitting light by natural changes when yellow phosphor is left in the air. This allows self-illumination at night without external light, but its time is short and its brightness is low. On the other hand, the fluorescent material emits a unique color of light that is completely different from the projected light when the light is projected.It does not emit light at all without external light, so it can be easily seen by vehicle drivers, but external light It is not very effective in conducting command, since it is difficult to identify each other in the absence of one another.

The main object of the present invention is to provide a light emitting label function using a light emitting means such as an optical fiber or a light emitting device strip which is much simpler than the conventional electric light emitting device panel described above, less likely to be damaged, and consumes less power and has a lower price. To provide a seat belt with.

It is also an object of the present invention to provide a seat belt having an enhanced light emitting label function with the advantages of electric and non-electric by using a luminous member together with the optical fiber.

It is also an object of the present invention to provide a seat belt having a light emitting function that facilitates night scene command by emitting light of a specific mark for identification between a site commander and a member or an operator in addition to a light emitting label that simply indicates the presence or absence.
