Description

A device for swimming is known, containing two parallel-arranged floats interconnected by a dam-post for accommodating the swimmer’s body and carrying paddle wheels, mounted on the axis in front of the floats, and a handle. However, such a device is limited in functionality, as it provides only the movement of the swimmer, in the water and can not contribute to learning to swim. The aim of the invention is to enhance the functionality by providing swimming training. This is achieved by the fact that the proposed device has copiers and disks with radial grooves mounted on the axes of the rowing masks, in which spring-loaded arms with rollers at the ends are placed for interacting with copiers, and a crankshaft mounted in the rear part of the floats and hinged-mounted hangers for placing the legs, with the arms attached to spring-loaded levers, and the i-axis of the crown wheels are kinematically connected to the crankshaft. On flash% 1 the described device is shown, general view; in fig. 2 - the same, side view; in fig. 3 - kinematic coupling of crankshaft crankshaft. The device contains two parallel floats 1, interconnected by a crossbar 2 for placing the swimmer's body and crossbars 3 and 4, paddle wheels 5 mounted on axles 6 in the front part of the floats, mounted on axles 6 copiers 7 and discs 8 with radial grooves 9 (see Fig. 3), in which spring-loaded levers 10 with rollers 11 are placed at the ends for interacting with copiers, handles 12 mounted on spring-loaded levers & 10, crankshaft 13 carrying hinged-mounted suspensions 14 for placing legs swimmer and fitter at the back of the floats. The crankshaft 13 is kinematically connected to the axles of the propeller wheels by a chain transmission including sprockets.

15, the chain 16 and the sprocket 17. On the floats are fixed ki; w 18,

Use the device as follows.

The swimmer places the body on the crossbar 2, legs in the suspension brackets 14, and the arms are placed with the rotary shaft 12 and through the muscular efforts of the arms the paddle is rotated: the wheels 5, from which the rotation is transmitted to the crankshaft 13 through the kinematic transmission. As a result, the legs, which are located in the suspensions 14, receive a forced movement, similar to the style of the crawl. The frequency of movement of the legs can be adjusted by selecting the appropriate gear ratios. Moreover, the handles fixed on the spring-loaded levers 10, make a curvilinear movement similar to the movement of the hand when sailing by the crawl due to rolling with rollers 11 {Jyp (7) having a given cnvol (formulas Rotational paddle wheels 5 tell the device translational movement.

In order to forcefully train the swimmer, it is necessary to set the device in motion from an external drive, as a result of which the comb wheels from the action of water will rotate and transmit the movement to the handles of the crankshaft.

The device can be used for training swimmers on land. For this, the device is mounted on supports.
