Description

The utility model belongs to sports training devices, namely to carving simulators for skiing.

It is known that during downhill skiing, several external and internal forces act on the athlete, and during the movement of the skier in a turn, two main external forces act on him - centrifugal and centripetal. An athlete achieves better results only under the condition of effective and faithful resistance to the above-mentioned forces, as well as the vector of their action. That is why, in the designs of most ski simulators, attention is paid to the athlete's efforts to more accurately and effectively resist the action vectors of these forces, that is, to the correct position of the skier's torso, legs and arms. The role of such simulators is especially important when working with young, beginner athletes, for whom, at the initial stage of training, the correct position of the body is a primary task, when muscle-joint memory is formed for the future. In addition, the need to work on the position of the body is also important for those who start skiing in adulthood.

Many different training devices are known for training skiers.

For example, a well-known device for simulating skiing movements (patent O5 Mo 7935033, class Ab6ZV 69/18, publ. 03.05.2011), which is made in the form of two arc-shaped rails in a horizontal plane, located on a frame, which, in turn, is placed at an angle to the horizontal plane. A carriage is mounted on movable rails, which contains two platforms for no. Platforms for legs are fixed on a carriage with the possibility of rotation around a horizontal axis. Handrails are provided to hold the skier. The carriage is connected to the frame through elastic elements that turn it from the extreme to the central position.

The disadvantage of this design is a very small amplitude of movement of the skier's legs between the extreme positions, as a result of which there is a slight inclination of the knees inside the turn. Due to this, the feet, as a projection of the skis, deviate from the horizontal plane by a slight angle, that is, the skis turn at a very small angle, while the modern technique of the cut turn requires the maximum inclination of the knees inside the turn (toward the center).

A ski simulator or snowboard simulator is also known (see application О5 Мо 2014243162А1, cl. АЕЗВ 69/18, publ. 28.08.2014), a separate version of which has two arc-shaped rails in the horizontal plane located on the frame. Mounted on rails with the possibility of movement

A carriage that contains two platforms for the feet. Platforms for legs are fixed on a carriage with the possibility of rotation around a horizontal axis. Moving simulators of ski poles are provided to support the skier. The carriage is connected to the frame with the help of elastic elements that return it from the extremes to the central position.

The disadvantage of this simulator is the same small amplitude of movement of the skier's legs between the extreme positions, as in the previous analogue. In addition, the presence of a saddle in this simulator significantly reduces the load on the skier's legs, that is, reduces training efficiency.

A known device for ski training (see patent 05 Mo 7090621, class A6Z3B 69/18, publ. 15.08.2006), which is made in the form of two arc-shaped rails in the vertical plane, located on the frame, and the ends of the arcs are located below their central part . A carriage containing two foot platforms is mounted on movable rails. Platforms for legs are fixed on a carriage with the possibility of rotation around a horizontal axis. Handrails are provided to support the skier. The carriage is connected to the frame with the help of elastic elements that return it from the extremes to the central position.

The disadvantage of this design is that the movement of the skier to extreme positions actually occurs in a straight line in the vertical plane, which leads to the fact that the soles of the legs are all the time in one plane-parallel position, with a very small angle of inclination. As a result, in extreme positions, the outer leg is almost completely straightened, which is unacceptable from the point of view of modern downhill technique.

I.V. Koshutin's simulator for alpine skiers and slalom is also known. (see patent of Ukraine for a utility model Mo 72443, class Ab6ZV 69/18, publ. 27.08.2012), which contains the main platform and connected to it with the possibility of moving left and right and simultaneous rotation clockwise or counterclockwise of the platform with ski mounts, and between the main platform and the platforms with ski mounts, additional platforms are installed with the possibility of rotation around their axes, each of which simulates one of the positions of either the slope, or the skis, or the body of the skier, and the harness connected to the dynamic suspension is fixed on the latter .

The disadvantages of the analogue include an overly complex system of platforms, which consists of a large number of components, which complicates its maintenance, increases the size of the simulator and its cost. During the athlete's training, there is no fixation of the parallelism of the lower legs, which can lead to the development of false muscle memory of the X-shaped position of the legs, and the presence of ski bindings on the platforms implies training exclusively in ski shoes. In addition, the dynamic suspension is attached to a fixed support through blocks, which slows down its reaction to the movements of the skier.

The closest analogue in terms of the set of essential features is a carving simulator, which includes a base with arc-shaped guide rails, a moving platform placed on them with foot platforms installed on its load-bearing walls with the possibility of rotation, a support rack with a dynamic suspension attached to its horizontal part, containing a safety belt and an elastic suspension halyard connected to it, the ends of which are securely fastened to the horizontal part of the dynamic suspension (patent of Ukraine for a utility model Mo 111567, class A6Z3B 69/18, publ. 11/10/2016).

The disadvantage of this design, chosen as the closest analogue, is the fact that the strong attachment of the ends of the elastic hanging halyard limits the mobility of the athlete when performing the technique of turning avalman or fast re-rolling, slows down the speed of his reaction due to the resistance of the stretched part of the elastic hanging halyard.

The basis of the proposed useful model is the task of creating a more convenient ski simulator by changing the known design of the carving simulator, which provides a quick response of the dynamic suspension to the athlete's movements and provides an opportunity to train effectively, including athletes of a high professional level.

The task is solved by the fact that in the ski carving simulator, which contains a base with arc-shaped guide rails, a moving platform placed on them with foot platforms installed on its load-bearing walls with the possibility of rotation, a support rack with a dynamic suspension of the athlete attached to its horizontal part, which contains a safety belt and a hanging halyard connected to it, according to the useful model, the hanging halyard is connected to the horizontal part of the support rack with the possibility of its movement with the help of a roller drive mechanism. In a specific version of the construction, the roller drive mechanism is made inside the tubular horizontal part of the support rack with tension rollers located in its cavity, dynamically connected to the hanging halyard, arc-shaped guide rails are made with a rise in their central part relative to the horizontal plane and can be made with the opposite by the bend of their side parts, and the central part of the rails is above their side parts.

The task is also solved by the fact that the load-bearing walls of the moving platform and foot pads are tilted forward at an angle of 57-25" to the vertical, and the axis of rotation of the foot pads is located at an angle of 57-25" to the horizontal, as well as by that the base of the simulator can be additionally equipped with movable handles with a drive mechanism and slalom poles installed in them to simulate real slalom conditions on the track.

The execution of the suspended halyard connected to the horizontal part of the dynamic suspension through the roller drive mechanism makes it possible for it to move freely during sharp "pendulum" movements of the athlete, without limiting him in his actions, at the same time reliably keeping his body in a suspended state, and the execution in a specific version of this the technical solution of the suspended halyard made of elastic material softens the dynamics of its movement, keeping it from the influence of gravity.

The implementation of the roller drive mechanism inside the tubular horizontal part of the support rack with tension rollers located in its cavity, dynamically connected to the hanging halyard, in the opinion of the author, is the most optimal technical solution from the point of view of ergonomics. The execution of arc-shaped guide rails with a rise in their central part relative to the horizontal plane and with the opposite curvature of their side parts, provided that the central part is higher than the side parts, creates conditions for training close to real conditions of movement on a slope, and the execution of a moving platform with foot pads with supporting (front and rear) walls inclined forward at an angle of 57-25" corresponds to the natural inclination of the lower leg of a skier, since ski boots have an inclination of 137-177. Since the front and rear bearing walls of the foot pads are inclined forward, the axis of rotation of the movable foot platforms will be deflected by the same amount of 57-25" to the horizon.

In addition, the load-bearing walls of the moving platforms have different lengths: the wall that corresponds to the heel of the shoe has a longer length. Due to the fact that the walls have different lengths, during the movement of the moving platforms around the axis of rotation, they will perform different amplitudes in the radius, that is, the heel of the fixed leg (boot) of the skier will be more removed than the bowl. When the foot platform is fully extended to the side with an inclination of 90", this value will be equal to the same 57-25". That is, during movement to the right and left relative to its own axis, the base of the moving platform in the line from the bowl to the heel will deviate at an angle from 0" to 25" in the projection on the horizontal plane. When viewed from the side in the vertical plane, because the axes of rotation of the moving platforms are deviated by 57-25" degrees, when moving from the right and left, the heel of the skier's foot (boot) will rise above the bowl of the foot (boot) and also at maximum displacement will reach the same value as in the horizontal plane, and the oscillations of the moving platform will be carried out in the range from 0" to 257. At the moment of the greatest deviation to the right or left (corresponding to the most active phase of rotation), the heel of the foot rises above the bowl, the moving platform for the legs, and with it the feet and, as a result, the skis, simulate movement on a slope with a slope of up to 25", which corresponds to a slope on the track of up to 46.6". During movement along the guide rails, the moving platforms also shift (turn) at the extreme points to the right and left by the same 57-25", which determines the position of the feet (skis) parallel to the line of the slope of the track precisely in the most active phase of the turn. Also, the simulator additionally contains mobile supports installed on its base with a mechanism for driving them and slalom poles installed in them, to simulate interaction with them during the athlete's descent on the track, while the movement of the mobile platform to the right or left will lead to the lifting of the slalom pole on the athlete. the fal of a dynamic suspension can be inelastic or elastic, made of latex, rubber, elastic cord, leather, etc., which allows it to react more quickly to the athlete's movements.

The elasticity of the fal is selected depending on the weight and the intensity of the exercises.

The use of an inelastic phalanx of a dynamic suspension allows the athlete to be statically suspended for the purpose of muscular fixation of the required body position in one or another phase of the turn.

The width of the leg position can be changed depending on the age, growth of the athlete and technique.

Leg platforms have protruding parts that fix the lower legs, which is important when working with beginners and children at the initial stage of learning, to fix the muscle-articular memory of the movement of the legs when turning, and also to avoid a gross mistake in the future when the knees legs are brought together in the so-called X-shaped driving, which does not provide an opportunity for uniform loading of skis when turning. When using the proposed guide rails on the simulator, the skier moving along them in the middle of the arc of the simulator (corresponding to the active phase of re-rolling between turns) will need to push the legs, and this will cause a slight deviation back, which exactly corresponds to the technique of turning avalman or rapid bending due to their sharp bending.

The carving simulator consists of a base 1, on which arched rails 2 are rigidly fixed with roller wheels installed on them With a movable platform 4 with front 5 and rear load-bearing walls, on which, in turn, foot platforms 7 are fixed with the possibility of rotation with protruding element 8 to support the athlete's lower legs. The movable platform 4 is connected to the base 1 by means of an elastic cord 9, which counteracts the centrifugal force and reaction of the movable platform 4, returning it to the central position. A support rack 10 with its tubular horizontal part 11 is attached to the base 1. The arc-shaped rails 2 are about 3 meters long, which allows the athlete to perform movements to the right and left with maximum amplitude, imitating real conditions on the track, and arc-shaped in the horizontal plane rails 2 are made with a rise in their central part 12 relative to the horizontal plane and can be made with the opposite bend of their side parts 13, and the central part 12 of the rails is above the side parts 13 (Fig. 6). This increases the angle of the skis (legs) toe, which is more in line with sports cornering and more accurately simulates the state of the athlete's body in its most active part at the moment of attack of the slalom poles installed on the slope. An additional (removable) support 14 can be attached to the base of the simulator 1 to support the athlete's balance. The simulator is equipped with a dynamic suspension, which consists of a safety belt 15 with a suspended halyard 16 attached to it, connected to a roller drive mechanism, which consists (Fig. 4) of 4 tension rollers 17 installed in the cavity of the tubular horizontal part 11 of the support racks 10. During movement, the skier is actually suspended on a dynamic suspension that simulates opposition to the centripetal force and the force of gravity and prevents the athlete from falling. Thus, the athlete, moving along the guide rails 60 to the right and left, and being suspended on a dynamic suspension, will be able to imitate the skiing technique of turning in general without hindrance. A separate implementation of the proposed simulator contains additional equipment designed exclusively for athletes who train in slalom and giant slalom (Fig. 7). Additional equipment is installed in front of the athlete and is attached to the base 1 of the simulator with the help of a hinged mechanism 18. The main supporting element is movable supports 19 with slalom poles 20 installed on them, movable supports 19 are installed on the hinges of the hinged mechanism 18, while the distance between the hinges of the hinged mechanism can be changed. In the free position, the slalom pole is tilted forward from the skier and from the vertical plane. The movable holders 19 are connected to the lever 21 for their lifting. Lever 21 is made in the shape of a triangle and has several holes for changing the arm of the lever. One end of the elastic cord 22 is attached to the lever 21 and then, through the system of blocks 23, the other end is attached to the moving platform 4.

The alpine skiing carving simulator according to the declared utility model is used as follows.

First, the athlete puts on the safety belt 15 in such a way that the points of attachment of the hanging halyards 16 to the belt are located opposite the hip joints, and its lower strap goes below the gluteal muscles to better support the athlete's body. The athlete stands on the foot platforms installed on the moving platform 4 and fastens the ends of the hanging halyards 16 to the safety belt 15. Then the athlete begins to swing the moving platform 4 with pendulum movements to the right and left, moving right and left on the wheels of the moving platform 4 along the arc-shaped rails 2 At the same time, the hanging halyard 16 moves inside the tubular horizontal part 11 of the support rack 10 along the tension rollers 17 located in its cavity. The elastic cord 9 helps the athlete to return to the initial position, which after stretching pushes the skier to the center of the simulator. During the exercises, beginners can hold on to the additional support 14 for balance, and more advanced athletes can do exercises with or without slalom poles. Athletes can imitate various techniques of alpine skiing, for example, standing in the rack of rapid descent, they can practice turns corresponding to this discipline. Additionally, for example, by getting into a suspended turning rack (hanging on an elastic suspended halyard), in one

From the turn, you can change the angle of attack and canting by direct rocking, both due to your weight and due to external influence (with the help of a trainer). Another important aspect of working with a simulator is static work. This is especially important for beginners. The elastic hanging halyard 16 is replaced by an inelastic one, but adjustable in length. After that, the skier hangs in the turn and the coach or instructor can set the correct stance at the moment of passing the turn, that is, physically correct the legs and arms and set the correct inclination and position of the athlete's body. In order to work out the technique of turning avalmans or rapid re-pointing due to sharp bending-unfolding of the knees, the design envisages changing the shape of the guide rails to rails with a bend of their central part 12 in the horizontal plane and with a possible opposite bend of their side parts 13. When using such guide rails on simulators, the athlete, moving along them in the area of the middle of the arc of the simulator (corresponding to the active phase of turning between turns), tightens his legs. For slalom or giant slalom training, additional equipment with 20 slalom poles and their drive mechanism is installed to the ski carving simulator. During the movement of the platform to the right or left, the elastic cord 22 is stretched and pulls the lever 21, which leads to the lifting of the movable handles 19 with the slalom poles 20 on the athlete, thereby simulating the attack of the slalom poles, as when passing the track on a real slope. Movable handles 19 with slalom poles 20 are lifted on the athlete one by one, depending on the position of the moving platform 4. The sequence of lifting the movable handles 19 can be changed by swapping the ends of the elastic cord 22 attached to the levers 21 from right to left. For slalom training in the position of the moving platform 4 on the right, the right holder is used (in the position from the left - the left), therefore, with this ratio, the holder 19 will rise in the direction of the athlete's body, and in the case of giant slalom training - on the contrary, with the position of the moving platform 4 on the right, the left holder 19 is used and, accordingly, in the position from the left to the right, that is, the handle will rise in the direction of the shoulder and forearm of the athlete, which corresponds to the technique of passing sports tracks in these disciplines.

Thus, the proposed useful model makes it possible to create a simple and easy-to-use ski carving simulator, aimed at acquiring the athlete's muscle memory for performing the correct modern carving turn, ensures a quick response of the dynamic suspension to the athlete's movements, while maintaining the correct inclination of the lower leg forward, and also gives the athlete the opportunity to practice the technique of turning avalman or fast cornering, slalom and giant slalom, and the coach - the opportunity to establish the correct position of the athlete's body in one or another phase of the turn, both in a dynamic and in a static suspended state.

As a result of the design changes, as the author's experience shows, the training and development of both beginners and advanced skiers in the skills of modern carving turns by repeatedly repeating exercises that directly affect the skier's musculo-articular memory and the development of coordination take place much faster , accuracy and automaticity of movements and, as a result, quick and error-free transfer of fixed skills to actions in real conditions.
