FLEXIBLE DUCTING FOR CABLES AND HOSES Russian patent published in 2006 - IPC H02G3/08 

FIELD: engineering of devices with flexible power carriers for ducting flexible electric cables, pneumatic hoses and the like from immovable portion of object to moveable portion, possible use in mechanical engineering, electric engineering, military engineering and other industrial branches.

SUBSTANCE: flexible ducting for cables and hoses is made in form of chain, consisting of jointly interconnected links with mutual rotation limiters. Chain links are made in form of U-shaped brackets with base and two side walls, and as mutual rotation limiters for links, side walls of bracket are used, projecting on one U-shaped end side of bracket beyond limits of base for distance L and having additional slant in lower portion at angle α to inner side of bracket base, while angle α is sharp, and vertex of this angle is directed towards bracket base. Mutual rotation limiters of links are positioned between side walls of adjacent links so, that limiter slant is positioned above inner side of base of adjacent link, and in bent position of ducting slants of mutual rotation limiters of links are in contact with inner sides of adjacent links bases, and in opened position of ducting, end sides of bases of aforementioned adjacent links are in contact with each other.

EFFECT: increased durability and reliability, possible manufacture of ducting of any length, width and bending radius.
