The leg simulator according to the first embodiment includes two means of moving 1 along a common rail 2, interconnected with platforms 3 with weighting agents 4. In the example of a particular embodiment, the rail 2 is made in the form of two parallel metal bent profiles 5, mounted on the sidewalls 6 with the formation of the upper and lower longitudinal slots 7. An example of a guide in the form of two parallel metal pipes mounted on the sidewalls 6. Each means of movement 1 includes interconnected support 8 and pressure 9 th trolley on castors. Each platform 3 is configured to adjust its angle of inclination relative to the horizontal plane by means of two hinges 10 on the slide bushings, providing a change of position relative to the front axis and one hinge 11, providing a change of position relative to the sagittal axis. The design provides for the possibility of fixing these hinges to limit the degrees of freedom of the platform 3 and facilitate the exercise. The outer sleeve of the hinge 11 is mounted on a vertical shaft 12, which in the lower part contains a seat under the weighting agent 4. The shaft 12 is installed in the axle box of the support carriage 8. Thrust and radial bearings in the axle box rotate the platform 3 and weighting agent 4 relative to the vertical axis. The weighting agent 4 is made in the form of a package of goods 14, held by the first latch 15 with the possibility of adjusting the weight. The platform 3 for the feet is equipped with a second latch 16, made in the form of a belt of polymer slings with Velcro.

The leg simulator according to option 1 operates as follows.

At the beginning of the exercises, the necessary load is formed by setting the necessary number of weights in the weighting materials 4. The trainee with his feet rises on the platform 3 and, by moving along the guide 2, carries out breeding and flattening of the legs. Depending on the task, the movement of the legs is combined with a change in the position of the feet by turning the platform 3 relative to the vertical, sagittal (right-left) and frontal (forward-backward) axes.

An example of the exercise is possible, in which the weighting materials 4 provide packages of cargo 14 of different weights or carry out the installation of the load 14 on only one weighting material 4. Changing the load, as well as the tilt angles of the platforms 3, brings the man-platform system out of balance, and then, balancing, establishes the balance etc. There is not only training of muscles and joints, but also the development of coordination of movements.

The leg simulator according to the second embodiment includes two means of moving 1 along respective guides 2, interconnected with platforms 3 with weighting agents 4. In a specific embodiment, each rail 2 is made in the form of two parallel metal bent profiles 5, fixed with end faces on the sliders 17 to form the upper and lower longitudinal slots 7. An example of a guide in the form of two parallel metal pipes is possible. The guides 2 are mounted parallel to each other on the supports 18 by means of sliders 17 interconnected with the horizontal components of the supports 18 with the possibility of adjusting the distance between the guides 2 by moving the sliders 17 of one of the guides 2 along the horizontal component of the supports 18 and fastening by screws 19. Each means of movement 1 includes interconnected supporting 8 and pressure 9 trolley on rollers. Each platform 3 is configured to adjust its angle of inclination relative to the horizontal plane by means of two hinges 10 on the slide bushings, providing a change of position relative to the front axis and one hinge 11, providing a change of position relative to the sagittal axis. The design provides for the possibility of fixing these hinges to limit the degrees of freedom of the platform 3 and facilitate the exercise. The outer sleeve of the hinge 11 is mounted on a vertical shaft 12 in its upper part, which in the lower part contains a seat under the weighting 4. The shaft 12 is mounted in the axle box of the support carriage 8. Thrust and radial bearings in the axle box rotate the platform 3 and weighting 4 relative to the vertical axis . The weighting agent 4 is made in the form of a package of goods 14, held by the first latch 15 with the possibility of adjusting the weight. The platform 3 for the feet is equipped with a second latch 16, made in the form of a belt of polymer slings with Velcro.

The simulator according to option 2 works as follows. At the beginning of the exercise, set the required distance between the rails 2. To do this, loosen the screws 19, move one of the rails 2 to the required distance from the other rails 2 and tighten the screws 19. Then, as in the first embodiment, select the training load, setting the required number of weights. A trainee with his feet stands on the platform 3 and moves his legs along the guides 2. Depending on the task, the movement of the legs is combined with a change in the position of the feet by turning the platforms 3 relative to the vertical, sagittal (right-left) and frontal (front-back) axes.

As in the first embodiment, an example of the exercise is possible, in which the weighting materials 4 provide packages of goods 14 of different weights or carry out the installation of the package of goods 14 on only one weighting agent 4.

The leg simulator according to the third embodiment includes two means of movement 1 along respective guides 2, interconnected with platforms 3 with weighting agents 4. Each means of movement 1 includes interconnected support 8 and pressure 9 trolley on rollers. The support trolley 8 contains an axle box in which a telescopic axis 20 is mounted through bearings thrust and radial. The telescopic axis 20 consists of an outer cylinder 21 with a seat for a weighting agent 4 and a rod 22 moving along a vertical axis, interconnected with a platform 3 for the soles of the feet by means of two hinges 10 on the slide bushings, providing a change of position relative to the front axis and one hinge 11, providing a change in position relative to the sagittal axis. The design provides for the possibility of fixing these hinges to limit the degrees of freedom of the platform 3 and facilitate the exercise. The outer cylinder 21 and the rod 22 are rigidly fixed to each other in certain positions with the finger 23, the mutual movement of the rod 22 and the cylinder 21 provides a difference in the heights of the platforms 3. The axial and radial bearings in the axle box rotate the telescopic axis 20 with the platform 3 and the weighting agent 4 relative to the vertical axis. The weighting agent 4 is made in the form of a set of weights 14, with the possibility of changing their quantity, is installed in the appropriate place on the telescopic axis 20 using the first latch 15. The weighting agent 4 is designed to complicate the translational and rotational movement of the telescopic axis 20 by adding the inertial load of the goods 14. Platform 3 for the feet legs is equipped with a second latch 16, made in the form of a belt of polymer slings with Velcro. In the example of a specific embodiment, each guide 2 is made in the form of two parallel metal pipes 24 fixed with end faces on the sliders 17. An example of a guide 2 in the form of two parallel metal bent profiles fixed with end faces on the sliders 17 is possible. The guides 2 are mounted parallel to each other on the support 18 by means of sliders 17, interconnected with the horizontal components of the support 18 with the possibility of adjusting the distance between the guides 2 by moving the sliders one of the guides 2 along the horizontal component of the support 18 and securing by screws 19. The simulator contains a handrail 25, mounted on the support 18.

The work of the simulator according to option 3 is carried out similarly to the work of the simulator according to the second option. A distinctive feature is the ability to adjust the level of platforms 3 vertically.

The inventive simulator in three options can be used as a means of training athletes, for health training, as well as a means of rehabilitation after injuries or transferred neurological pathologies. The simulator develops the ability to provide controlled arbitrary complex movement of the lower extremities, which is very important primarily for athletes. The range of movements formed by the simulator obtained in different efforts, the change of stresses create the opportunity for the rapid formation of the required motor skill. The simulator can enter the basic system of training athletes who, during the performance of sports tricks and exercises, are supposed to have extreme types of movements of the lower extremities with different amplitudes of movements. Good basic training will prevent injuries and improve the quality of these exercises.

The inventive simulator can simulate the movement of a person on an uneven surface and can be used to develop coordination, which will help prevent falls and injuries. The simulator is suitable for people with different levels of training as it allows you to independently choose the amount of load and time of the lesson.

The simulator is very effective for preparing the vestibular apparatus, on which the possibility of realizing a person’s motor abilities greatly depends. Here, such an important component matters as the orientation of the body in space with a sharp change in position, which is so characteristic in sports. In this aspect, the simulator’s functionality is aimed at: developing legs for the ability to maintain balance; on the education of a heightened sense of direction of movement of the body and limbs; to regulate the level of effort in certain muscles, at different positions.

The inventive simulator in any of the three options meets the requirement of compactness and versatility. It can be used both at home and in the gym. Settings and adjustments are clear even to a beginner. The multifunctionality of the impact is solved by alternating the number of different movements. In the first embodiment, a combination of movements of the legs relative to the frontal axis with a change in the position of the feet left and right, back and forth around the vertical axis. In the second variant, a combination of movements with the feet relative to the sagittal axis with a change in the position of the feet is similar to the first variant. In the third embodiment, a combination of movements of the legs relative to the sagittal axis with a change in the position of the feet left and right, back and forth, around the vertical axis at different heights of the feet. The variability of the exercises, in addition, is provided by the ability to set a different level of load, different speed of execution, emphasis on a specific account, stops for straining legs in extreme positions, etc. Servings of contrasting efforts during mutual change give serious, direct, deeply penetrating cells, tensions with a long lasting effect. Such efforts are long-term effects in long-term memory.

The simulator in all versions allows you to practice the movements characteristic of different sports. Therefore, it can be recommended for inclusion in the training process, primarily in such sports as hockey, soccer, ice skating, skiing, boxing, weightlifting, swimming, sports dancing, where voluntary movement of the lower limbs is very important.

The simulator was created taking into account the natural movements of the human body, which ensures the safety of training, the absence of unnecessary load on the joints and, as a result, the minimum risk of stretching or damaging muscles and ligaments.

During the exercise, the speed and volume of blood flow is restored, the lymph flow improves, joint mobility improves, fascia and tendon elasticity develops, the skeletal system is supported, coordination of movements is restored, and therefore the brain’s work.
