TIP FOR FREE END OF ROPE PIECE OF FLEXIBLE LOCKING AND SEALING DEVICE Russian patent published in 2014 - IPC E05B39/02 

FIELD: construction.

SUBSTANCE: tip for the free end of the rope piece is made of a thin-wall metal and fastened on it by flush moulding with its outer surface; tip is made of tube or member rolled into tube, having the end portion for moulding and operation portion for interaction during locking with fixing member of the rope piece. The tail section of the tip under moulding is made by means of expansion. Tip 5 on the lateral surface is provided with the lock element 10, which is formed either by two symmetrically positioned rectangular transverse grooves-windows 10.1, or by two symmetrically arranged longitudinal grooves-windows 10.2 (fig. 10), or one neck 10.3, or rod with head 10.4 rigidly fixed therein (fig. 12), or one longitudinal groove disposed symmetrically or hole 10.5 (fig. 13), formed on the pin, or one-sided bevelled teeth made on its lateral sides. Locking element interacts during formation of broken feedback loop after driving device into the closed position with lock.

EFFECT: widening of the tip arsenal, enhanced functionality capabilities of tips for their subsequent interaction with self-locking mean in the closed state of the device during formation of broken feedback loop.
