Description

{SAFETY DIAGNOSTICS LIGHTING VEST FOR WORKING IN DARK PLACES}

The present invention relates to a safety vest, and more particularly, to a safety vest for safety diagnosis, in which a worker can illuminate a work area more widely in a state where both hands of a worker are not free at night or in a dark working space, The present invention relates to a lighting vest for safety diagnosis.

The vest for safety diagnosis is a vest worn by a worker in a work space for safety diagnosis, and a vest equipped with a storage space for storing lighting, tools and the like for convenience of work. The safety vest is firmly worn through fastening means such as an attached Velcro tape or buckle.

The safety vest is worn by a diagnostic person in order to diagnose safety in a space for safety diagnosis (for example, under construction, under construction, during use, after use, bridges, buildings, structures, etc.). The safety vest has to be placed in a dark space or a room without light compared with a conventional safety vest, and a safety diagnosis should be made. In addition, since both the safety diagnosis procedure and the safety diagnosis apparatus should be used, both hands are not free.

However, there is no dedicated vest for safety diagnosis, and safety diagnosis is carried out while carrying a conventional safety vest and carrying a lighting apparatus or the like. Conventional safety vests are equipped with reflective vinyl paper of white or bright color system along the waist circumference or shoulder circumference, and a luminous paint is applied thereon or a luminous tape is attached thereon so that an operator who is working at night or in a dark place is recognized have.

However, the above safety vest is not only insufficient in the quantity of light that reflects light, but also has a sufficient discrimination against reflected light from the surroundings, so that the safety function of the night worker wearing safety vest is sufficiently secured There was a shortage.

Korean Patent No. 10-0692197 (Published on Mar. 13, 2007) discloses a technique for a light-emitting safety vest using a high-brightness LED optical device. However, this prior art has a problem in that a prismatic LED The device is arranged in a band shape so that it may be sufficient for the purpose of recognizing the worker from the outside. However, there is a problem that it is difficult to use the device in such a level that it can illuminate the work area brightly and enable convenience of night work.

Therefore, there is a need to develop a new concept of a safety vest for safety diagnosis, which enables a safety diagnosis worker to identify a safety diagnosis object at night or in a dark place, and to widely illuminate the work area even when both hands are in an unnatural state .
