Projectile stabilizing fins have separate locks with facing snap hooks to engage a fin opening from both sides to hold the fin securely in the extended position for flight

摘要

The projectile has a number of stabilizing fins (2) for guidance, which are extended from a rest position into an extended setting when in flight. When extended, the fins (2) are held in place by a locking mechanism (4), with a locking unit (5) for each fin (2) with two facing snap hooks (6,7). The extended fin (2) is held firmly between the two snap hooks (6,7), which engage an opening (11) in the fin (2) from both sides of it. The locking mechanism (4) is of a plastics material.
