SEALING DEVICE OF INCREASED RELIABILITY Russian patent published in 2009 - IPC E05B39/02 

FIELD: protection means.

SUBSTANCE: invention is related to devices for locking and simultaneous sealing of railway cars, containers, vans. Task of invention is development of reliable, simple to manufacture and cheap sealing device, with increased resistance to criminal breaking-in. Sealing device of increased reliability is proposed, which comprises body, rope, having passive part, rigidly or with the possibility of axial rotation connected to body, and working part passed in position of final assembly through longitudinal hole of body, spring-loaded stop elements arranged in the form of four rollers of various diametre arranged pairwise on both sides of working part of rope. In body there is insert having internal cavity with inclined walls, inside of which there is separator arranged in the form of truncated wedge, also having internal cavity with inclined walls, in which there is the first pair of spring-loaded rollers of smaller diametre, which interacts with rope and inclined walls of internal cavity of separator. The second pair of rollers of larger diametre is installed in cavity of insert on upper plane of separator and interacting with rope and inclined walls of internal cavity of insert. Inside insert there is profiled orifice installed with the possibility of free axial rotation, and internal holes of which follows profile of cross section of rope arranged in insert recess, coaxially to its longitudinal hole. The second same type of orifice is installed in separator recess on its upper plane, coaxially to longitudinal hole of separator.

EFFECT: high manufacturability and increased resistance to criminal breaking-in.
