Snap hook with roller for automatic locking

摘要

The snap-hook (shackle) comprises a roller (8) mounted so that it can rotate in a first curved zone (3) of the body (1), and interacting with the finger (bar) (7) in order to prevent the finger from being opened in all orientations of pivoting of the roller (8) except for an unlocking orientation in which it allows the finger (7) to be opened. The pivoting of the locking roller (8) is provided by a fastening link (17). A pull exerted on the fastening link (17) brings about automatic locking. Unlocking is provided by causing the snap-hook body (1) to pivot with respect to the fastening link (17).
