SWIMMER FLOATATION IDENTIFIER Russian patent published in 2008 - IPC B63C11/02 B63C11/30 

FIELD: sport.

SUBSTANCE: invention relates to water sport, ballasting and balancing of underwater swimmer and swimmer's outfit. Identifier structure consists of leak tight air reservoir, e.g. 3 litre plastic box, and ballast - leaded billet with negative floatation - 3 kg, which is a counterbalance for positive reservoir floatation. If reservoir is filled with water, floatation can be changed from 0 to -3 kg by water inlet/outlet knob when positive floatation is measured. If billet is removed - from +3 kg to 0 at negative floatation. Volumes to be filled are defined according to scales with marks at each 0.1 l and figures at each 0.5 l. Measurement parameters will increase from +6 to - 6 kg of swimmer floatation with appropriate outfit if billet and two 1.5 l air reservoirs are added. Floatation identifier is provided with suspension system and balancing reservoir to bring identifier to zero floatation.

EFFECT: simplification of structure; more compact; possibility to change negative and positive floatation parameters of underwater swimmer.
