Abstract

The mechanism is for use with missiles launched from a barrel or other suitable device, having a lever pivoting at a fixed point, one end of which, in the retracted position, bears against a shoulder on a part of the fin to be extended, while a holder works with the lever and bears against the inner wall of the barrel. The holder is in the form of a flexible blade (16), one end of which bears against the barrel wall, while the other end has a pin (14) with a flat section (15) formed on it, against which the lever (11) bears. The pin can be accommodated in a notch formed in the fixed fin.
