Abstract

Przedmiotem zgłoszenia jest element zabezpieczający trzpień, zbudowany z drutu stalowego wygiętego symetrycznie względem osi pionowej charakteryzuje się tym, że drut (1) wygięty jest naprzemiennie dwukrotnie w kabłąk do wewnątrz i na zewnątrz tak, że wewnętrzne wierzchołki (2, 3, 4, 5) wygięć opierają się symetrycznie w czterech punktach o zabezpieczany trzpień a symetryczne ramiona na końcach są zwrócone do wewnątrz trzpienia i tworzą dwa dodatkowe punkty (6, 7) styczne z trzpieniem przy czym zewnętrzne punkty zagięć drutu leżą na jednym okręgu.
