FLEXIBLE LOCKING-SEALING DEVICE Russian patent published in 2011 - IPC E05B39/02 G09F3/03 

FIELD: construction.

SUBSTANCE: device comprises a rope section (1), one end (2) of which is passive, and the second free end (3) when locked is pulled through an inlet (4) and outlet holes (5) and a passage channel (6) arranged between them to form a loop and is fixed by means of a locking mechanism (7), which comprises fixing elements (12) in a separator (11) arranged in the cavity (8) of the body (9) and spring-loaded with a closure spring (10). The body cavity is closed with an upper (13) and lower covers (14), equipped with accordingly the inlet (4) and outlet (5) holes to pull through a rope section arranged coaxially to the body axis and to the passage channel (6), which is arranged in the separator (11), which has a lower wall (15). The upper end of the closure spring (10) rests against the lower wall, and its lower end rests against the lower cover (14) and interacts with a stabiliser of the closure spring arranged in the form of a bushing (16), a hole (17) of which communicates with the outlet hole (5) in the lower cover (14). A facility to prevent unauthorised access inside the body is made in the form of an orifice (18) with a profile opening (19), which complies with the profile of the rope section cut (1), installed in the body (9) at the support with the possibility of rotation. According to the invention, the orifice is arranged in the cavity made in the upper cover (13) and is installed on the support made in the form of a plate equipped with a central hole for passage of the free end (3) of the rope section, fixed together with the upper cover (13) in the body (9). The orifice (18) is made of material that makes it possible to do the profile opening (19), which complies with the profile of the rope section cut (1), as a process piece of the rope is pulled through the device as assembled, at the same time its profile is identical to the profile of used rope section cut (1), and the diameter is at least equal to the latter, besides, its both ends are equipped with a lead-in. The diameter of the hole in the orifice (18) prior to pulling is selected so that it is equal to at least the diameter of grooves formed by rope strands. The device is equipped with a drainage system to drain liquid from the body cavity (8), which is made as a drainage hole (26) arranged in the lower part (27) of the bushing (16) that communicates with the output hole (5). On the body (1) there is a place provided for application of a reference identification marking.

EFFECT: higher extent of device protection against unauthorised access.
