The invention relates to sports, in particular to training devices and simulators for rowing on the Cy Hie.

The purpose of the invention is to simplify the design.

The device contains a base consisting of two grooves with a double-threaded groove; front I and rear 2. On the back tube of the base seat 3 is put on, and on the front side there is a foot rest 4 for the form. with the base and the platforms, which is zak) a braking device with a ko () pus 5, in which there is no pivot hole | 101 () the giga (strap) brake bending is missed in the temporary crowd, (a | ilepple on face and the other) - I a torus torus 7 by means of carbines I is not confused).

The front tube is connected by a thread that is inside the end: the auxiliary tube and the finger 9, (acted on the front tube (Fig. 7). On the left side of the rear tube there are 1) seat stopper from pro-1HH () T () displacement. In the body of the seat there is a bottom 11 and a hole 12, into which the check-stopper 13 is inserted, entering with its split “klk:) vom into one of the apertures: adnei t () cuts basics. Moreover, this B1,1em has an el. Shape, long diameter, which is perpendicularly located perpendicularly to the axis of the base (Fig. 13, 14 and 15).

A foot worn having a similar for SITO canon, 1 15 and a check 16, falls on the front end of the tube. check 13. On the tube, respectively, for this check, there is a locking notch 17. On the front part of the foot rest, there is an eyelet 18 at the bottom, in which the movable arm 19 is placed and the hinge is fixed in it by the axle 20.

freely mounted on the body of the movable bracket. Sver.hu movable crown crowns secured brake assembly, having a body 5, made in the form of a bracket with eyelets 22 at the ends. A support roller 23 is inserted into the holes with a hole 24, with which it is seated on the upper end of the moving crown of the thane so that it can rotate. Inside the bracket there is a movable holder 25, also made in the form of a bracket, in holes 26 of which another axis 27 of the pressure roller 28 is fixed. This axis is placed in longitudinal slots 29 located on the bracket of the case and on the ends of the holder, limiting clamps 30. In the gap A spring 31 is placed between the brackets, resting on one side into the wall of the movable cage, and on the other side into the washer 32, into the central hole 33 of which the pointed end of the adjusting screw 24 screwed in), the screw hole 35 oppositely located th wall of the bracket body. The check has a gripping head and a split rod with a roller in the working face (not marked). The paddle simulator has handlebar tubes 36 with end lugs (rings) 37, mounted on the centers, 1 stem 38 and fixed with similar checks. 39, running out into recess 40, located on the stem.

By. 1zuk1ts simulator in p moves, when leaving the competition, is business trips, etc. as follows.

The simulator is removed from the IC: 1 8 and collected. Screw the tubes and 2 and put the seat 3 on the back of the tube 2. Stop it with a check 13, insert it into one of the arms K). Then put the stop 4 for the shabby insert the front

the end of the front tube 1 into the channel 15 and the stopper with a clamp 16. The T is attached (a brake strap 6 to the simulator of the oar 7 (carbines wear pa end rings) The simulator is ready for operation

The athlete sits in seat 3, hands-on the simulator of the oar 7, and “rows the hook, as taken on a kayak. With it, the I.1 of the initial position (the right in front and the brake belt is threaded to the left) is inserted. There is a weight with the right blade, 1a, i.e., the wiring is on the right, and the left hand respectively moves forward. In this way, the brake belt is skipped on the left, and on the right, a gap (gap) is pulled and drawn between the support 23 and the brake rollers 28 of the brake evil. Due to the presence of a variable thickness of the belt, (namely, it is thickened in the middle and thinner towards the ends), the force for stretching the belt does not remain constant, but the video changes: first, the load is small, and then the thickness of the belt is thicker. It increases and reaches a maximum in the middle of the belt. Then after passing through his middle

through the brake assembly (which corresponds to the position of the paddle blade to the right of the rower's body, at the place where maximum force is applied during real rowing) the load decreases, a gradual (as the belt becomes thinner) failure occurs, characteristic of that rowing moment, when the maximum wiring is reached and the paddle is removed from water, moving backward by inertia. Having completed the stroke on the right, the sportman thus prepared the trainer for the left stroke, which is carried out in the proposed way, only to the left side.

The movable spring-loaded bracket 19 thus performs two functions: it lengthens the period of increase in the load of the resistance of the brake assembly, i.e. it makes the increase in the applied force for reaching its maximum smoother and longer compared to the decrease in the load that takes place after passing the thickened part of the belt between the rollers, it moves the point of application of the rower's force to the wiring line (Fig. 10). When padding to the right, at the beginning of it, under the action of the spring 21, the movable arm fits in a vertical position. But later, with an increase in the pulling force through the brake assembly, this bracket begins to move to the right. With increasing force, its slope increases and the maximum angle of inclination and maximum tension of the spring 21 is reached when the maximum paddle movement is performed by the oar, i.e. at that moment when the fixing point (upper end of the bracket) of the oar simulator the force is most pronounced to the right, which is exactly what is required both to increase the component of the wiring to the peak of the load, and for convenience and rationality of the stroke movement itself. After the wiring is completed, when the load is relieved, In the case of a bent spring 21, the movable arm with the brake assembly returns to its original position and the left paddle proceeds similarly to this description, only to the other side.

The rower height adjustment is made along the length of the simulator and the paddle,

for which the seat 3 is moved, and the handle tubes 36 are moved apart and secured by checks in the required directions and magnitude. Adjusting the load is carried out by tightening (screwing in) or loosening (unscrewing) the adjusting screw 34 in housing 5. Compressing the brake belt or loosening it between the rollers 23 and 28 causes the force required to apply to pull the belt, i.e. “wiring” Finally, it is possible, by replacing the brake belt, to change the nature of the load dynamics, for which it is necessary to keep in stock a set (set) of the corresponding belts having different thickness slopes.

After training, the simulator is disassembled in reverse order and inserted into the package 8 for transportation.

The simplicity of the design allows it to be widely used in various conditions.
