FACILITY TO MONITOR UNAUTHORISED OPENING OF FLEXIBLE SEALING-LOCKING DEVICE Russian patent published in 2013 - IPC E05B39/00 

FIELD: construction.

SUBSTANCE: facility to monitor authorised opening of a flexible SLD comprises a body 1 and a section of a rope 2, one end of which is passive 3, and the second free end 4, equipped with a tip 5, is sent via the inlet 6 and outlet 7 holes of the body and a throughput channel 8 between them to form a loop and is fixed in it during closure by means of a locking mechanism 9, placed in the body. At the same time the facility to monitor unauthorised opening is made in the form of a fixator 12 interacting with a stop 10 on the neck of the tip 5 after its pushing via an autonomous hole 11 for the tip 5 with formation of a non-working reverse loop. According to the invention, the fixator 12 is arranged in an autonomous module 14 tightly closed with a module lid 13, comprising a body shell 15 and the specified autonomous hole 11 for the tip 5 and capable of being installed on the device. As the example, in the dwg.3 the fixator 12 is made in the form of a tab washer (i.e. the washer fixing with inner tabs), stiffly fixed together with the module lid 13 in the body shell 15, interacting in the closed condition with a stop 10 on the tip neck 5, at the same time the autonomous hole 11 is made in the module lid. The autonomous module may be mounted on the passive end of the rope section or is fixed on the body of the device itself.

EFFECT: invention makes it possible to increase extent of SLD protection from its unauthorised opening.
