FLEXIBLE FIXING-COMBINING DEVICE WITH HIGH CRIMINAL RESISTANCE Russian patent published in 2018 - IPC E05B39/02 

FIELD: construction.

SUBSTANCE: device contains body 1, closed by front 2 and rear 3 lids, and cut of rope 4, one end of which is a passive 4.1, and second loose end 4.2 with tip is passed through input 5 and output 6 openings and is located in between passageway 7 with the formation of a loop and fixed in it when closing through locking mechanism 8 hosted in the cavity of body 1. The device is provided with means forming the bend of rope segment, the axis of which is aligned with the axis of the body cavity. According to the invention, means forming the rope segment bend is made in the form of an insert 9 mounted in a groove 1.1 formed in body 1 in the upper part above the passageway 7. Insert 9 in the cross section is made in the form of two parallel narrow rectangular bars, united by the ends with radius rounding and rectangular notch 9.2 in the connecting area to ensure mobility and spring insert properties when interacting with the groove walls and keeping it in a groove. In the front part, the insert is made with a rounded radial shape, similarly to it, the opposite part of body is made in radius form. Lower surface (part) of insert 9, with introduced rope segment provides an offset its axis in small sizes (within 0.2-0.5 mm), i.e. when passing the rope segment, its axis will bend across the insertion length 9. Lower surface of insert 9 is provided with one-side chamfered teeth 9.3, which create additional braking as rope segment 4 is moved while trying to pull it.

EFFECT: increased criminal resistance.
