Description

The invention relates to sport, in particular to adaptations for training rowers on land.

The aim of the invention is to increase the effectiveness of training by using biostimulation,

The device comprises a base in the form of a composite support rail 1, installed at the ends on the stops 2 and in the middle, in the place of the connector - on the brake ferrule 3. On the support rail there are two seats 4 placed against each other, in the middle of it the junction is installed brake-vibration mechanism, mounted in the cage, which contains a segment of square pipe 5, mounted in the cage vertically. Inside the pipe there is a bed (support) with a tooth b (Fig. 4). The tooth 6 is fastened with the help of a bolt 7 and has a longitudinal groove 8 for the passage of vertical chain links 9. On top of the tooth, an emphasis 10 is placed in a pipe in the form of a glass with a rounded base. Inside it is placed the brake spring 11, abutting against the upper part of the bearing washer 12. The end of the adjusting screw 13 with the handle 14 screwed into the threaded hole 15 located in the center of the cover 16 of the square pipe is on top of this washer. There are windows 17 in this pipe that form the pro

a longitudinal incision where a brake copy 18 with a chain is inserted, placed between the tooth (bottom) and the stop (top). At the ends of the brake copy and chain in the common bore, the arms grippers 19 are attached (Fig. 2.3). Each gripper has a rod 20 (FIG. 10) with an open lug 21 for fastening with a cam and a chain. On the rod there are elongated lugs 23 (FIG. 9) longitudinally cuts 22, fixed at the ends of the handle 24. The handles themselves are hinged at the ends of the arc 25 attached middle to the end of the rod, on which a damping spring 26 is mounted. eyelets. The handles are mounted on axles x 27 and eyes 28, located at the ends of the arc. There is a notch 28a on the handles on the top.

Seat carriage - standard. It has a vertically triangular yoke 29 attached to it (Fig. 6) in the corners of which on the axles x 30 there are fixed support rollers 31. The two upper rollers are at rest on the top 32 of the guide frame, and the lower one of the lower 33 of the bed. The support guide 1 has two components, each of which has abutments 2 at the ends, trimmed from the bottom. The middle parts of the components have holes 34 for fastening them to the holder with bolts 35 (Figs. 3, 5). On the cage, side steps 36 (foot stops) are fastened in the form of removable plates installed in the side of the cage in slot 37 (Fig. 5) with their projections 38 having locking bars 39 (. 13) abutting the side planes of the cage. The copier has a longitudinal groove 40 (fig. 8) for placing the chain. On the threaded part of the rod 20, the grip 19, the nut 41 is pressed against the spring 26 (Fig. 12),

Use the device as follows.

Two athletes from the garden of the vehicle on the seat-carts 4, set their feet with the soles of the shoes on the footrest 36 and take the grippers 19 in their hands, holding them by the handles 24. Then they start rowing, as required by the technique of rowing on the steam bath. Two modes are implemented: without vibration, with vibration.

No vibration. When water is seized, the athlete with his legs bent and arms outstretched is in the initial position (left part of FIG. 1), Resting his feet on the steps 36 and pulling the handle 24 on himself, he paddles and finishes it in the position shown in FIG. 1 on the right. At the same time, he pulls the brake copy machine 18 with a chain 9 through windows 17, i.e. between the stop 10 and the tooth 6, preloaded by the brake spring

11, which creates friction resistance, i.e. simulates the resistance of the aquatic environment. At first, the friction is low, since the copier is thin here. Then the friction increases with increasing

thickness copier 18, and then falls again. This simulates the stroke. When rowing, the athlete moves back to the carriage seat 4, which then rolls back on the support rollers 31. Entrance and preparation

0 to the next stroke also occurs when the seat moves -carts forward. This is carried out completely passively - the opposite rower and no athlete to his side and puts him & initial position. So, with effort and relaxation, athletes train in rowing. In this case, the grippers allow, firstly, to soften these movements by compressing the shock absorber spring 26, which is compressed, because it is attached to the elongated eyes 23, moving backwards together with the handles 24. Secondly, they imitate the handles move as the handles of real oars 5 move. rotate around their axes 27 (Fig. 11).

This is rowing and training. The load is regulated by an adjusting screw 13, which, when

0 screwing in presses the stop 10 to the brake copy 18 and to the tooth 6 and increases the friction and, consequently, the load, and when unscrewed by the handle 14, vice versa. reduces the load. At the same time need

5 tighten or loosen the nut 41 (FIG. 12).

With vibration. On the copier 18 from the bottom they put on the chain 9 - they put it in the longitudinal groove 40 (Fig. 14). The eyes of the copier and the last link of the chain are put on the open hole of the grip 21 of the grip 19, Vibration when running and skidding is carried out due to slipping of the links of the chain 9 strengthened from the bottom of the brake copier between it and the tooth 6, where it passes through the longitudinal groove 8 of this tooth those chain links that are perpendicular to it. Each link that comes to the junction, which is put on the edge, increases sharply the load on the muscles of the arms and other muscles of the athlete, and after

0 passing its load drops sharply. This creates a vibration. The amplitude and nature of the vibration is controlled by replacing the circuit. A fine chain gives a large amplitude of vibration, and a high link 5 less. Frequency can be set using a chain with longer or shorter links. So the range of regulation is very wide. The vibration noise is canceled by a copier, which is made of a semi-solid material, as well as

the fact that the device has rubber stops 2 and a clip (bottom) 3, as well as a rubber damper-silencer (not shown) in the form of a hard rubber piece, is attached to the bottom of tooth 6.
