Abstract

FIELD: sports equipment for swimmers and divers. SUBSTANCE: flipper has foot fastening 1 and blade, which, in preferred embodiment, has two longitudinal lateral ribs 4 and transverse hydraulic vanes 5 attached between ribs 4. Connecting member 3 provides for pivoting of blade relative to horizontal axis to both sides from initial position with resilient returning to the initial position. Rigidity of lateral ribs 4 continuously or discretely reduces toward blade rear edge. EFFECT: increased efficiency, improved pulling force of each hydraulic vane when paddling direction is changed, increased convenience in usage and provision for individual adjustment of flipper. 15 cl, 9 dwg

Изобретение относится к спортивному снаряжению для пловцов и ныряльщиков и может быть использовано как для увеличения скорости передвижения, так и для поддержания наиболее экономичного режима плавания. Ласт включает крепление 1 ступни, соединительный элемент 3 и лопасть, которая в предпочтительном варианте исполнения состоит из двух продольных боковых ребер 4 и поперечно расположенных гидрокрыльев 5, закрепленных между боковыми ребрами 4. Соединительный элемент 3 обеспечивает возможность поворота лопасти относительно горизонтальной оси в обе стороны от исходного положения с упругим возвратом в исходное положение, а жесткость боковых ребер 4 непрерывно или дискретно уменьшается в направлении к задней кромке лопасти. Изобретение позволяет повысить КПД ласта, увеличить тягу каждого гидрокрыла 5, обеспечить дополнительную тягу при перемене направления гребка, повышает удобство в пользовании и обеспечивает возможность индивидуальной подгонки ласта. 14 з.п. ф-лы, 9 ил.

The invention relates to sports equipment for swimmers and divers and can be used both to increase the speed of movement, and to maintain the most economical swimming mode. The fins includes a foot mount 1, a connecting element 3 and a blade, which in a preferred embodiment consists of two longitudinal side ribs 4 and transversely mounted hydraulic wings 5, mounted between the side ribs 4. The connecting element 3 allows the blade to rotate relative to the horizontal axis in both directions the initial position with an elastic return to the initial position, and the stiffness of the side ribs 4 continuously or discretely decreases towards the trailing edge of the blade. The invention allows to increase the efficiency of the fins, to increase the thrust of each hydro wing 5, to provide additional thrust when changing the direction of the stroke, increases ease of use and provides the possibility of individual fitting of the fins. 14 s.p. f-ly, 9 ill.
