<p>The invention relates to small-sized floating transportation means for aquatic recreation and can be used for tourism, sports competitions and as a training device. The inventive water cycle comprises floats, a connecting frame, a pedal drive which is kinematically connected to a horizontal fin and drive and driven chain wheels which are interconnected by means of a chain. A connecting rod is hingedly attached to the driven chain wheel and to a bar. The bar is in contact with a movable articulated support, which is fastened to a movable bracket and to which a lever, used for adjusting the position of the support on the bar, is connected. Themovable bracket is in contact with a guiding bar and is horizontally movable therealong. The horizontal fin is attached to the bar end. Said invention makes it possible to simplify the structural design for the water cycle and to increase the operational efficiency of a propelling device.</p> |
