Abstract (en)
1. A marine propeller with collapsible blades, comprising at least two blades (1, 2) articulated relative to a propeller shaft (3), the blades being adapted to move between two positions (inoperative and operative positions), and a mechanism (6) for synchronising the movement of the blades, to synchronise their transfer movement (debattement) between their two positions, the synchronising mechanism comprising a connecting member (7) which is mounted to slide axially relative to the propeller shaft (3) and which co-operates with each of the blades (1, 2) of the propeller, characterised in that the feet (1a, 2a) of the blades (1, 2) of the propeller are housed in an axial slot (5) in the end of the propeller shaft (3) and are articulated relative to the propeller shaft (3) by means of one transverse spindle (4).
