Abstract

Zespół kotwi ciernej mający ogólnie rurowatą kotew wyznaczającą wnękę rozciągającą się wzdłużnie przez kotew, mającą przecięcie rozciągające się wzdłużnie wzdłuż kotwi. Przez wnękę przechodzi wzdłużnie trzpień. Rozszerzający element jest zamontowany na trzpieniu lub ukształtowany integralnie z nim, na przednim końcu trzpienia lub przy nim, oraz wystaje przez przedni koniec kotwy. Rozszerzający element ma powierzchnię sprzęgającą zbiegającą się w kierunku tylnego końca trzpienia. Łeb napędowy jest zamontowany na trzpieniu lub jest ukształtowany integralnie z nim, na tylnym końcu trzpienia lub przy nim. Trzpień można wprawiać w ruch przez ruch obrotowy łba napędowego, aby ciągnąć rozszerzający element w kierunku tylnego końca kotwy tak, że powierzchnia sprzęgająca sprzęga się z kotwą, odkształcając promieniowo na zewnątrz kotwę na jej przednim końcu. Zespół kotwi ciernej może mieć środki do co najmniej zasadniczo uniemożliwiania ruchu obrotowego rozszerzającego elementu względem kotwy.
