The device comprises a base in the form of a support arc 1 with a pelvic platform 2 fixed on it and restrictive arcs 3. A guide pipe 4 is attached along the pelvic platform in the middle, into which another transmission rod 5 is placed with the possibility of limited rotation. In front of this rod-tube has an eyelet 6, inside which on the axis 7 is placed the front block 8 of infinite flexible thrust, for example chain * 9. The ends of the axis 7 are made lugs 10, in each of which through the fingers 11 are pivotally attached levers -12 of the drive arm movement. Each lever is a triple telescope made of faceted tubes. Its base 13 (FIG. 8) has an eyelet 14 for attachment with said eye 10. The second telescope tube 15 is inserted into the base and has a hook 16 (FIGS. 7 and 9) in the form of a hook covering the edge of the copier 22. The second the tube is placed the third tube 17, at the end of which is fixed the arm 18 of the handle, having the tube 19, mounted on the arm 18 for rotation. On the tube attached to the support plate 20 brush, equipped with a fastening strap (not indicated). To the axis 7, in its middle base, on the sides of said eyebolt 6, brackets 21 (Fig. 6, 3, 4, minimum two) of copiers 22 spanning the indicated axis 7 are attached. The hem along the circumference of the copier has a bend (not indicated, FIG. 15) ).

Behind the pipe-rod 5 there is a removable flange 23 (FIG. 12) for restricting and fixing the pelvic platform 2 from longitudinal movement. In the middle part of the tube-rod, a chest platform 25 is put on it with its tubular base 24. The platform is fixed on the tube-rod with clamping screws 26 and 27. (FIG. 3). In the middle of the tube-rod, within the borders of the pelvic platform, there are transverse grooves (not indicated, FIG. 6) for placing the end face of the clamping screw 26, which, falling into one of the grooves, limits the longitudinal movement of the tube rod, but allows it to rotate relative to the longitudinal axis, what is needed to adjust the device for the growth of an athlete. Flexible thrust 9 (Fig.3, 5, 11) is located below the pipe-rod. Its rear part covers the other - the rear unit 28 (Fig. 10) of the transmission, which is placed in the rear eyelet 29, made in the shank 30 of the support arc 1, and fixed to the axis 31, with which it rotates, along the same axis on the sides detachable cams 32 are fixed from block 28. Cams are installed either, the working parts of which are separated at an angle of 180 °, i.e. located diametrically, in diameter, or cams with four working parts located crosswise. On the axis 31, with its end attached removable flywheel 33 (11) with the handle 34.

The movement of the legs also includes two telescopic rods, each of which has a rod 35 (FIG. 10), which is fitted with a tube 36. At the end of the tube, an eyelet 37 is provided, with which an anchor eye 39 is articulated via an axis 38. plate 40 of the foot holder, having a fastening strap 41. The tube has a longitudinal notch 42 in which a fixing screw 43 is screwed into the body of the rod 35. The other end of the rod 35 has an opening 44, which it joins hinge to the scarf 46 through checks 45 behind the support arc 1. A row of holes are made horizontally in the kerchief - for swapping the indicated checks 45 when changing the shoulder of the boom overpressure supported by the lower surface of its rod 35 on the indicated cam 32. These holes are shown by dotted lines.

he inserts the handpieces under the fastening belts 21 and places 20 handles on the support plates. Feet with feet inserts under the mounting straps 41 of the support plate 40 of the foot lift (the support plates of the arms and legs are bent according to the configuration of the palms and upper surfaces of the feet). Then the learning process begins. It consists of 3 stages. '

At the first stage, learning takes place on land. The learner familiarizes himself with the general coordination of movements and masters them. To do this, the instructor, sitting on a chair at the simulator, rotates the flywheel 33 by the handle 34 and rotates the axis 31, and with it the cam 32, which causes the checks 45 to move vertically relative to their axis, creating imitating movements of the swimmer. If double cams 32 are installed, then a two-impact crawl is realized (with four cams - four-stroke). Thus, the rotation of the flywheel sets in motion the foot drive, which forcibly moves the swimmer's legs along the required paths of the actual swimming.

At the same time, movement through flexible thrust (chain) 9 is transmitted forward - to manual drive. Its front block 8 is rotated, which causes rotation to its axis 7, and therefore, the telescopic arms 12 begin to move in a circle relative to the copiers 22. This leads to the student's forced movement of the hands. Since the grippers 16 all the time keep the middle tube of the levers at the edge of the copiers 22, the ends of these levers reproduce the trajectory of the copiers themselves, only in an enlarged form (Fig.7), forcing the hands to move both during strokes and when they are carried over the required for swimming trajectories. In this way, both the trajectory of the movement of the legs and the hands is reproduced, and the correct coordination of the work of the arms and legs, which is typical of a two-impact (or four-impact) crawl, is carried out.

Then the student continues to consolidate the acquired skill in the skill. He independently moves his hands, focusing attention on the correctness of movements. Flywheel 33 can be removed. As a result of conscious movements, the arms and legs automatically, while still unconsciously, move along the required trajectories of the crawl until the trainee has mastered firmly the skill with his hands. Then the trainee is invited to work with his feet, keeping his hands at rest. After mastering and understanding the movements of the legs, training is again held in the joint

work hands and feet slowly at first and then

and at a fast pace. Hand and foot skills

is fixed.

Then there is a further improvement in swimming skills — mainly the fixation of the coordination of arm and leg movements. In this case, the student acts independently, at the direction of the coach, consciously and purposefully trying to stretch his arms as far as possible forward ~ at the beginning of the stroke and backward - at the end of it. Here the third tube of the 17 telescopic arms of the hand drives is triggered. They are pulled out of the second tubes and make the trajectories of the hands more gentle - stretched in the anterior-posterior direction, which provides a more efficient stroke, i.e., improves the swimming technique in terms of the overall coordination of arm and leg movements, the presence of copiers on both sides causes trainee to hold the elbow with a raised hand, which is also one of the important requirements of training, which is completely satisfied here. In addition, the swimmer's body is twisted, as it should be in real swimming. This is achieved by the fact that the thoracic platform 25 swings in the transverse direction together with the tube-tube 5 of the transmission in the guide tube 4 of the pelvic platform 2. And the pelvic platform is permanently fixed and does not swing on the support arch 1. The fall of the learner is eliminated due to the restrictive lateral arcs 3 .

At the second stage, training is continued in the water. The device is installed in a pond at such a depth that the body, arms and legs of the student are on the surface of the water, slightly buried, and the head is above the water. The sequence of practicing movements in water retains the same, only more attention is paid to the coordination of movements with the flywheel removed, i.e. from the work of the hands of the learner. In addition, movements of the head are mastered in the water for breathing — the intake of air above the surface of the water and exhalation of it into the water.

At the third stage, the student works out movements in the water, outside of the support on the device, i.e. without its use, since at the third stage it is practically not required, It is only necessary to periodically return to the simulator in especially difficult cases and to correct the skill with the tendencies of its violation.

Adjustment of the device is carried out on growth of the athlete. This is achieved

moving the tube-rod 5 inside the guide tube 4 of the pelvic platform 2

by tempering and subsequent clamping of the clamping screw 26, as well as the chest platform - by screw 27. Adjusting the amplitude of movement of the athlete's legs is carried out by shifting the end of the rod 37 with the hole 44 in the holes of the scarf 46 by fixing the check 45. When the telescopic rod is fed backwards, the lever arm increases and the amplitude of movement also increases, and vice versa. The length of the arms and legs is taken into account by the corresponding advances of the respective telescopes. For coarse adaptations, the device is made in several sizes.

Thus, the device allows you to form the ability to swim, consolidate the acquired skill and adjust it.

Since the training is carried out mainly in a compulsory form (both arms and legs are forced to move), you need to start training on this simulator as early as possible - even preschool children - silly people who do not perceive any instructions and instructions. The sooner they start learning, the better.

The proposed simulator will serve as a good help for training children in the presence of a reservoir, and especially in the absence of water, when the use of the pool is sporadic. When the simulator is executed in several sizes (height), it is possible to train both teenagers and adults.

Training of sports masters (correcting mistakes, switching to a four-stroke and six-stroke crawl, etc.) is also possible and necessary in normal conditions, and when access to the pool is limited. It is possible to use the simulator for general physical training. Swimmers can improve their skills both in adapted training areas and at home - without water.
