From the prior art, a simulator for training the lower leg is known, equipped with a footrest, while it consists of two skids (P), which move on a concave support along guides (f) due to the coordination mechanism [M], consisting of a cable [8], installed in a closed loop above a row of rollers [7] and connected to the base [P] by means of connecting elements [4 and 5] and ribs [a] (see RO 113944 B1, published 12/30/1998).

In the prior art, a trainer is known comprising a base structure having a walking surface substantially equal to the length of the user's stride, said surface slopes upward from the bottom to each end to form a front and back, and has a smooth surface over which the user's feet can slide, and the surface is such that lines perpendicular to the two parts of the surface intersect essentially at the waist of the user of the device (US 2,842,365 A, publ. 07/08/1958).

The technical problem of the prior art is to expand the arsenal of tools for a specific purpose, which is solved by creating a technical solution that is alternative to known solutions.

The technical result consists in the implementation of the stated purpose by the simulator, as well as the possibility of creating force on the working muscle groups: the gluteal muscle, the back of the thigh, the front of the thigh, the upper part, the deep pelvic muscle, the lower part of the back muscles.

The technical result is achieved by the fact that the simulator for the lower extremities includes a base consisting of side walls interconnected by means of transverse elements, to which a pair of arcuate guide skids is attached, a movable platform moving along the arcuate guide skids, and a loading mechanism, while to the side fixed support platforms with platforms for placing feet with heel stops are attached to the walls of the base, the movable platform contains rollers interacting with arcuate guide skids, and a platform for placing the foot, on the upper part of which there is an emphasis for the heel, the loading mechanism is placed under the pair arcuate guide skids and contains an expander attached to the base at one end, blocks, one of which is attached to the free end of the expander, and the second is placed on the axis connecting the side walls of the base, and a flexible element passed through the blocks and attached to the base at one end, and the second end is attached to the movable platform.

The features characterizing the above constructive implementation of the claimed simulator are essential and necessary for the implementation of its purpose.

The presence in the claimed simulator of a loading mechanism, fixed support platforms with platforms for placing the feet, and a movable platform interacting with arcuate guide skids, provides alternate exercises of the lower extremities and, accordingly, the possibility of creating force on the working muscle groups: the gluteal muscle, the back of the thigh , front thigh upper part, deep pelvic muscle, lower back muscles.

Thus, each feature characterizing the specified design implementation of the claimed simulator is necessary, and together they are sufficient to achieve the specified technical result.

The implementation of the supporting fixed platforms in the claimed simulator for the lower extremities is removable ensures its compactness during storage.

The presence of additional rollers in the movable platform, interacting with arcuate guide skids, the axes of which are mutually perpendicular to the axes of the main rollers, ensures the stability of the movement of the movable platform when performing exercises - moving the legs back.

The implementation of all rollers with annular recesses interacting with cylindrical arcuate guide skids provides an increase in the interaction surface of these rollers with cylindrical arcuate guide skids, which ultimately also leads to the stability of the movement of the movable platform during exercise.

In the claimed simulator for the lower extremities, the expander can be made in the form of a spring.

The claimed invention is illustrated by the following figures.

Figure 1 shows a general view of the simulator, figure 2 is a side view of the claimed simulator, figure 3 is a top view of the claimed simulator, figure 4 is a side view of the movable platform, figure 5 is a front view of the movable platform, figure 6 is a diagram of load application.

The simulator for the lower extremities includes a base 1, consisting of side walls 2 interconnected by means of transverse elements 3, to which a pair of arcuate guide skids 4, 5 is attached, a movable platform 6 moving along the arcuate guide skids, and a loading mechanism 7. fixed support platforms 8 are attached to the side walls of the base with platforms for placing the feet, having stops for the heels 9, which can be made removable. In one of the design versions of the claimed simulator, the platforms for placing the feet can be made inclined to the side of the heel rest. The movable platform includes rollers 10 interacting with arcuate guide skids, and a platform 6a for placing the foot, on the upper part of which there is a stop for the heel 11. The loading mechanism is placed under a pair of arcuate guide skids and contains an expander 12, for example, in the form of a spring, one end attached to the base, blocks 13, one of which is attached to the free end of the expander, and the second is placed on the axis 14 connecting the side walls of the base, and the flexible element 15, passed through the blocks and attached to the base at one end, and attached to the movable platform. The movable platform contains additional rollers 16 interacting with arcuate guide skids, the axes of which are mutually perpendicular to the axes of the main rollers 10. All rollers can be made with annular recesses 17 interacting with cylindrical arcuate guide skids.

The claimed simulator for the lower extremities operates as follows.

The practitioner becomes one foot on a fixed support platform, the other leg is located on a movable platform. When the leg located on the movable platform is pulled back, the expander is tensioned, which sets the target load on the working muscle groups: the gluteal muscle, the back of the thigh, the front of the thigh, the upper part, the deep muscles of the pelvis, the lower part of the back muscles.

Training takes place alternately on two legs.

An example of an exercise on the claimed simulator.

Stand with one foot on the platform of the fixed platform, with the other foot on the platform of the movable platform (trolley). When performing the exercise, it is necessary to keep your back straight without leaning forward, for this, rest your hands on the wall and look up. Try to maintain this position during the exercise. Take the leg standing on the cart back, slowly and without bending at the knee. Return to the starting position, resisting the quick return of the cart. Do the desired number of repetitions and change legs. Repeat the same movements with the other leg.

The dimensions of the structure are designed for comfortable use by an adult from small to above average height.

Guide arched skids are made with a circle diameter calculated for the best biomechanics of the exercise.

The elasticity of the expander is designed for the safe exercise of a healthy adult and includes the ability to adjust the tension.
