FLEXIBLE LOCKING-SEALING DEVICE Russian patent published in 2013 - IPC E05B39/02 G09F3/03 

FIELD: construction.

SUBSTANCE: flexible locking-sealing device comprises a body and a section of a rope, one end of which is passive, and the second one is free and is stretched via a through hole and fixed in it by means of closure with the help of a stop. The through hole is made as conical with an inlet hole of smaller section at the side of the rope section entry. The body is equipped with a stop at the side of the rope section exit. The stop is installed on a part of the through hole length at the side of the stop and is made in the form of a collet, having swages, tops of which are arranged in two parallel planes perpendicular to the axis of the rope section. Number of swages in each plane is at least three, and the inner diameter of the collet is less than the diameter of the rope section, the cone of the through hole is arranged with a small angle of self-braking, and the stop is formed by rolling. The collet is made as solid in the form of a steel thin-walled bushing, upper swages of which are made in the form of tabs with a rounded top, formed by separating longitudinal slots, which are dead in the lower part, which form lower swages in the form of links, and pilot longitudinal slots, arranged symmetrically relative to the tab top, which are dead in the upper part.

EFFECT: increased locking reliability.
