Swim flipper

Abstract

A swimming fin with a foot part (1, 3, 4) attachable to a swimmer's foot and a swimming fin vane (2) attachable to the foot part (1, 3, 4) is described. The swimming fin vane (2) comprises an elongated holder (5) and at least two streamlined blades (7, 7i, 8, 8i) arranged protruding laterally from the holder (5) and rotatably arranged in both directions by a predefined angle. According to a first object of the invention, the swimming fin is characterized by a movable arrangement of the elongated holder (5) relative to the foot part (1, 3, 4) attachable to the swimmer's foot. According to an alternative or additional second object of the invention, the swimming fin is characterized in that the streamlined blades (7, 7i, 8, 8i) protruding on opposite sides in relation to the longitudinal axis (9) of the holder (5) are interconnected via a plate-shaped crossbar (46). The plate-shaped crossbar (46) runs through a hole (45, 45i) in the elongated holder (5). The hole (45, 45i) in the elongated holder (5) is equipped with blade movement limiters (47, 48) in the form of protrusions and has a larger size than the crossbar (46) passing through it.
