The device contains an inclined rack 1, mounted on a support 2 in the form of a frame. In the eye 3 there are articulated pillars (half-axes 4. phi and 2). the holder 5 is fixed, in the channel of which a longitudinal bracket 6 is inserted at the back this bracket has a shank 7 from above - a head restraint 8, and in front - a TODUO head 9. 9. At the rear of the casing there is a pelvic platform 10, and the pectoral platform 11 is attached to its front part 12. is available at the bottom of the clamp hani. the shank is attached melena installed in the shaped hole 14 of the shank

rod 15. missed into an eyelet (also with a shaped hole) 16. Springs are put on the rod: rear (weak) 17 and front (strong) 18. Adjusting nuts 19 are screwed on the front and rear of the rod. Nozzle 9 is made in the form of a tube. It has bevels on the front, on which the lugs 21 (FIGS. 5 and 6) are hinged by means of fingers 20, accommodating movable blocks 22. Flexible connecting rods 23 are slung over these blocks, at the end of each of which is fixed a handle 24 with a lock (shock absorber ) 25 brushes. The head restraint has a shell 26 (Fig. 7) in the form of a tube mounted on a bracket with a tightening screw 27 and an inclined stand 28 on which the headrest 30, stabilized on the stand-31, is fixed by a ball joint 29.

The brake mechanism is mounted under the pelvic and thoracic platforms. It contains two pairs of drums and two brake cylinders 32 (pneumatic). Each pair is made up of a large 33 and 34 small drums (Fig. B), mounted on a common axis - a finger 35 (Fig. 9) fixed below the pelvic platform. Each hub of a large drum is fixed and wound in one row of flexible ha ha 23 (turns superimposed on each other) and fed forward to the movable block 22. The snare drum is fixed ha 36 (FIG. 8), the other end of which is missed. in the brake cylinder, attached to its piston 37 and acts as a rod. The cross section of the brake rod is rectangular. On one of the wide surfaces of her made figured combined bypass groove 38 (Fig.12). T ha is made of flexible no neshego material. It enters the cylinder through a calibrated slot 39 (Fig. 11) located in the bottom 40 of the cylinder, into the body of which an adjusting screw 41 (Figs 11 and 3) is screwed with a calibrated end 42, which is included in the figured-combined bypass groove (Fig. 13). The other side of the cylinder cap does not have. On this side, the end of the rubber damper (depreciation harness) 43 (11), which is attached to the piston, is missed into the cylinder. The other end of this bundle is fed to the bracket attachment and fixed to it from the side using eyelet 44 (Figs. 3 and 6). The brake cylinders are attached to the chest platform with the help of fingers 45 (Figures 9 and 11) entering the hole in the eyelet 46 located on the wall of the cylinder, which allows fixing the cylinders (hang them) so that they can swing in a horizontal plane . The ends of the cylinders adjoining the snare drums are adhered by the cross member 47 (Fig. 9), which secures them from vertical movement, but allows them to move horizontally within certain limits.

Big and snare drums are spring loaded to each other. A spring 48 (Fig. 9) is placed in the hub of a large drum and rests on its inner flange 49 0 (Fig. 10). With its other end, it rests on the snare drum hub, pushing the drums apart from each other. To prevent them from turning one. Regarding the other, in a compressed position, the slots 50 are made on the outer surface of the snub hub of the small drum, and corresponding slots 51 are made for them from the inside of the hub of the snare drum. To press the drums to each other and dock them at the 0 end pin axis 35 has a thread on which a locking nut 52 (fig. 3) is screwed with finger grippers 53. The nozzle 9 is locked with a tightening screw 54 (FIG. 2).

5Use the device as follows.

in a way.

The following modes are implemented: 1. Crawl on the chest. 2. Crawl on the back. 3. Brass. 4. Butterfly (dolphin).

0Krol on the chest. The swimmer rests on the pelvic platform 10 so that the chest platform 12 is under the chest, puts the hands into the arms 24 under the latches 25, puts his head on the head restraint 30 and 35 works in the same way as the swimming technique on the chest requires. When padded with the right hand, the handle 24 is fed down and back and forth along the set trajectory and the swimmer performs a pull and then a 40 push. When the handle moves along the path, it pulls behind it and bends a pull 23, which winds up from the big drum 33 and rotates it. This rotation is transmitted through the notches 51 and the splines 50 to the 45 snare drum 34, which rotates in the same direction and winds itself (in one row) to the brake cable 36. This pipe is pulled out of the cylinder 32 and carries its piston with it. 37, which compresses the air in the space between it and the cover (bottom) of the 40 cylinder. The compression of air provides a braking effect, which also helps to stretch the rubber cushioning harness 43.

55 The braking dynamics of the piston, and hence the handles, are set according to the law of a real hand stroke in water: i.e. first, the load increases when air is compressed, then it reaches a maximum due to further compression of the air.

then at a certain distance this maximum is maintained due to the fact that at this point the clearance of the bypass hole between the body of the flexible rod and the wall of the calibrated slot 39 in the area of the calibrated groove 38, which is expanded in this place, increases. Finally, the load decreases, a breakdown occurs and the arm moves from the stroke area to the zone of carrying. At this point, the calibrated groove expands even more, the air passage clearance in the calibrated slot increases, which ensures the indicated reduction in load. Then the clearance again changes - it decreases, and this creates braking on the piston and the handle if the swimmer didn’t finish the stroke and pulled his hand out of the water. When the arm is carried, the bending brace 23 is wound on the drum 33 and the slacks that occur when changing the direction of movement of the brush from the paddle and the transfer is chosen due to the fact that the stretched rubber damping cord is compressed during hand pulling, pulls the piston with the brake drum, which is unrolled from the snare drum 34, rotates it and the snare drum.

Similarly, the other autonomous part of the braking device works with the left hand stroke. Due to the autonomy of each half of this mechanism, it is possible to engage in the grip when the beginning of the stroke with one hand is carried out before the end of the stroke with the other hand, which is realized with high skill in swimming.

The back rabbits are performed in the same way, only the swimmer is in a supine position and the head rests on the headrest 30 with the back of his head, lowering his chin on the chest.

Brass is carried out while lying on the chest, as in the crawl on the chest, only the hands do not work alternately, but at the same time along a different trajectory. In general, the trajectory of each hand during the stroke is significantly shorter than in the cradle. To provide these shortened strokes, for example, during a stroke, where the trajectories take the form of a keyhole, the palms of the hands are moved side-to-side, then brought together, and after the stroke they are moved forward again for the next stroke. To meet this requirement, the increase in inhibition should occur earlier than in the cradle. This is ensured by the fact that the piston in the cylinder moves forward, for which purpose the brake rod is pulled up on the snare drum hub. That's what the drum docking system is for. Nut

five

52 (FIG. 3) is unscrewed for this, which frees the spring 48 (FIG. 10), which feeds the hub of the snare drum 34 down, which removes the splines 50 from engagement with the notches 51, which ensures that the snare drum is relatively large. After winding the brake rod for the required distance, the small drum is manually moved to its original position and stops the screw-bolt 10 of the nut 52. In addition to the winding, the adjusting screw 41 (FIG. 13) is screwed into the bottom of the brake cylinder, thus blocking the gap (the hole section becomes less) the gap between the bottom of the cylinder and the body of the brake rod. All this together, plus pushing together with the piston of the rubber cushioning harness 43, creates the required shortened and increased braking dynamics, which 20 is required for the breaststroke.

The butterfly (dolphin) is realized, like the breaststroke, only the stroke paths are somewhat lengthened by moving the piston and adjusting the lumen with a screw 41. In 25 the difference from other methods of swimming in the butterfly (dolphin) is the bending and extension of the body in the same position. and hip joints. These movements are ensured by swinging the yoke 5 together with 0 platforms 10 and 12. In this case, the strong spring 18 balances the oscillating part of the device and the swimmer’s body, ac; 1zba, the spring 17 dampens this part when the athlete’s body bends and he lifts 5 of his upper body ( 2).

The adjustment of the device is carried out according to anthropometric parameters, i.e. along the length of the arms and torso. To install the devices along the body, unscrew the clamping screw 13 (figure 2) and move the chest platform 12 forward (if you need to increase the support area) or backward (with a smaller increase in occupancy), and again lock it with screwing the clamping screw 13. The flexible rods 23 in this case also vary in length, for which they are compressed or skipped on the big drum 33 by twisting this drum after undocking it in a specified manner from the snare drum 34. When the platforms are moved one relative to another one moved under the cross bar 47.

Along the length of the arms, the device is adjusted by moving the tool 9 (Figures 1, 2, 5 and 6) after releasing it by unscrewing the screw 54 and then fixing it on the fixed distance of the mobile units from the chest platform. The length of the flexible cable at 11 ° is established by the indicated extension - by reeling this rod on the drum 33.

When the load on the hands is adjusted, the adjustment is performed twice; either by changing the ratio in the winding of tg to the drums (if winding is reduced at the hub of a large drum and simultaneously increased at the snare drum, the load will increase, and vice versa), or by screwing or unscrewing the adjusting screw 41 (when screwing in, the clearance decreases and the load increases, and vice versa).

The proposed device is lighter and more compact than the known devices, more versatile (for all swimming methods) and reliable because it is simple in design, and most importantly, it better imitates the real stroke, the dynamics of the load of stroke and carrying and their movement paths in all known navigation methods. . It will be required for the training of swimmers of a different class both under the conditions of the hospital and at the exits when the teams of swimmers go to competitions and to training camps. The proposed device can be used not only for training swimmers, but also for general physical training, for equipping gyms and physical training corners at home.
