JP6049026B2 - Life jacket for rock fall protection with removable safety band for fall prevention - Google Patents

Description

  The present invention relates to a lifeguard for rockfall protection provided with a detachable fall-preventing safety belt, and more specifically, to a lifejacket for rockfall protection worn by an operator mainly at an industrial site, particularly at a tunnel construction site. The present invention relates to a life jacket for rock fall protection provided with a detachable fall prevention safety band integrally configured to be detachable and integrated with a safety band to be worn in order to prevent a crash accident or the like.

  Usually, in various industrial sites, an operator wears a safety jacket for falling rock protection in order to prevent a safety accident caused by falling rocks.

  In particular, when working in a high place in a tunnel, work is performed in an environment that is exposed to the risk of falling rocks and falling, so a safety belt for falling prevention that can be worn with a life jacket for falling rock protection is necessary to prevent falling death. .

However, the worker may inevitably have to wear a life jacket for falling rock protection while wearing a safety belt first. In this case, the wearer must wear the life jacket for rock fall protection with great care by the safety belt connecting ring and rope attached to the back and the side. Accordingly, a lot of wearing time is required, which is not only troublesome, but also has the disadvantage that the back and flank portions are inconvenient due to such deposits and the wearing feeling is lowered.
Therefore, there are many cases where safety belts for preventing crashes are not worn due to such problems, and this is a situation where safety accidents such as crash deaths frequently occur.

  Further, in industrial sites such as construction sites, a safety band for preventing a fall is integrally formed and worn on a general safety jacket. The “safety jacket” of Patent Document 1 is designed to be easy and fast to wear by sewing together and fixing a safety belt for preventing fall on a safety jacket worn by an operator at various industrial sites, The possibility of loss due to separate storage can be resolved.

  In addition, the “safety belt integrated work clothes” of Patent Document 2 integrates the safety belt inside the work clothes so that the safety belt can be easily worn and the risk of a safety accident can be reduced.

  However, such an existing safety belt-integrated safety jacket cannot be used at a tunnel site where there is a risk of falling rocks.

  In addition, the existing safety jacket may be worn quickly by the work at the construction site, and the safety belt for preventing the fall may be cut by the load that is continuously transmitted. Furthermore, such a safety belt-integrated type safety jacket causes a waste of resources because the entire component must be discarded when either the jacket or the safety belt cannot be used.

  Moreover, such a safety belt-integrated safety jacket is a leg belt type that is worn so as to wrap the lower body. Therefore, it cannot be worn with a waist belt type that is not a leg belt type, and there is a possibility that the lower body belt may be twisted when the clothing is worn without wearing the leg belt type lower body belt. In particular, when the vest is not worn, the belts for each part of the safety belt are intertwined or twisted, which is inconvenient when stored or stored.
