Our proposed invention distinguishes itself from the present invention, in particular, in that the trainer / skier summarizes the information from the screen-line and carries out the reaction of his body in order to use such movements in a certain order to try, through a mechanical system that has built-in sensory, to successfully control the skier on the screen so that it remains on the track, which is SW-o fixed.

A more detailed description of the invention is explained below with a description of the case and the submitted images showing:

The described invention, which is represented by this patent application, replaces active skiing training with the skier not needing ski equipment, and the exercise is also enabled in enclosed spaces, a floor plan of at least 2 x 3 m.

It can be used in apartments, public areas (fitness centers, hotels, ski schools, academies, etc.) in the courtyards or outdoors without restrictions, except for the 220V power supply needed to power the PC's PC.

The entire technical system consists of a frame 1, a television 2, a computer PC with a keyboard with built-in SW-rom 3, pulses 3.1 and 3.2, and a power cable 4.

The frame 1, which is technically the most important part of the invention, consists of a receiving rod 1.1, a running track 1.2, which is wrapped in radius R, a lower connection 1.3, in which the straps are rubberized elastic 1.5 connected to the trolley 1.4.

The receiving rod 1.1 is screwed onto the frame 1 so that it can easily be folded forward or backward in the direction of the frame symmetry 1, or the entire screwdriver for transport purposes. The screwing is carried out in known possible technical modes, which are not the subject of this invention.

Skier S is standing on a trolley 1.4 and his hands are held by the receiving rod 1.1. A PC with a built-in built-in SW-rom sends a moving picture-track line with a picture of skiing via a pulse connection 3.1. a selected track recorded on a SW-ru which is in a known way connected to a PC to a TV 2 where it is displayed as a two or three-dimensional film. Television or The TV screen 2 can also be a projector or some other imaging device. PC 3 has the ability to process the SW-ski, which is built into PC 3 via soft wear, based on input data, processed by skier S through sensors KT and 1.4.2.4, V scales, also process audio signals that simulate the skiing of skiers by snow, ice, etc. This audio signal also processes PC 3 via pulses 3.1, to a display 2, which can be a television, projector or similar device. The image and sound display 2 will be referred to as television 2 hereafter

Skier S, in the direction of P, observes a picture on television 2, where a line with a door 2.1 and a picture of a skier 2.2, which runs through the door in a certain direction, is shown. Skier S, with the movements of the foot moves the trolley 1.4 left or right in the direction of the SG. The trolley 1.4 is held in the center of the running track 1.2, the prestressing elastic 1.5 which is fixedly mounted on the trolley 1.4 and is mounted in the lower link 1.3 over the wheel. Depending on the complexity and weight of the skier S, we can cling from 0 to 15 elastics 1.5 on a trolley 1.4. and in this way, we change the tension of the trolley according to the complexity and weight of the skier. Elastics 1.5 can be tensioned from 0 to 500% of elastic length 1.5.

Skier S moves the carriage 1.4 in the direction of the SG and thus passes through the CT contacts, which measure the deviation of the trolley 1.4 from the center of the track 1.2.

KT Contacts can be continuous or discontinuous. In the event that (KT) are discontinuous, they are implemented, for example, stepper motor. That is to say, they are distributed in length, partially, and moved as close as possible to each other, to form an approximation of the continuous contacts, thereby enabling the finest information of moving the cart 1.4. If we use discontinuous contacts, these are positioned between 1 and 5 mm in length, from 10 to 170 cm in length from the center of the track 1.2 on each side. In the case of the selection of continuous contacts (KT) (such as a potentiometer), they are mounted continuously from the middle of the tread line 1.2 from 10 to 170 cm to the left and the same to the right of the treadmill 1.2.

The trolley 1.4 at a particular position on the line 1.2 electrically travels certain KT contacts which send signals to the PC, which through the SW converts to the movement of the picture of skiing 2.2 in the image of television 2.

When the skier S receives information on the next position of the ski image 2.2 in the image of the television 2, according to the door of the track 2.1, the skier S takes the decision of the movement to the left or to the right, which is done by moving the legs and consequently by moving the trolley 1.4 on the track 1.2. The trolley 1.4 takes the next position on the track line 1.2 and initiates the appropriate KT contacts that determine this position.

KT Contacts resend the signal via a 3.2 pulses connection to the PC, which sends a new image via the SW via the pulses 3.1 connection, with the new position of the ski slide 2.2 on the TV 2. Skier S, with the view P re-processes the new image and moves through the movements trolley 1.4 on the treadmill 1.2. Thus, the control loop is closed and repeated as long as the training takes place.

The skier is gradually gaining experience and is always better and more quickly adjusting the position of the trolley 1.4 on the treadmill 1.2, according to the SW, which shows the dynamic picture of the skier 2.2 whose skier S actively leads between the gates of the track 2.1. SW-ri can cover all known and unknown ski slopes. The speed of the ski track 2.2 can be adjusted according to the difficulty of using SW-ra.

Television 2 can be plain television, and the impulse connections 3.1 and 3.2 are known state of the art and are not specifically addressed in this invention. The PC is connected via a power cable to a 220V or 230V network or batteries hidden in a PC or external battery.

The present invention provides, insofar as it has a built-in slider with a DN winding and a battery A, it is also intended for so-called self-sufficiency. For the purposes of self-sufficiency, a 1.4-inch slider from the DN winding is installed on the trolley 1.4 which, by moving the trolley 1.4 in the direction of the SG, creates a magnetic flux accumulated in a battery A that can be a component of the PC or a separate standalone unit. The conversion of the kinetic energy through the electric winding, or the slider with a winding DN, which moves over a core, which is in this case a running track 1.2, is a known state of the art, but for this purpose it is not yet used. It is also known state of the art to preserve this energy in accumulations.

The frame 1 can be placed on the floor of the training area directly or through the V scales, which measure the mass of the whole system with the skier S. The scales V also measure the impulses of forces generated by the movements of the ski S or, trolley 1.4 per treadmill 1.2. These impulses of force and mass of skiing S can be transmitted from the SW computer PC, which can enable even more sophisticated guidance of the skier 2.2, as it obtains data on the accelerator trolleys 1.4 in the direction of SG and in the longitudinal direction if the scales are at least three and a mass skier S. V I take it that we want to measure accelerations / decelerations even in the longitudinal direction, or in the direction perpendicular to the direction SG, the frame 1 must be supported by at least two scales V on the left and the right in the direction of the SG and at least one scales V front or rear. However, the frame 1 may be supported by four V scales, in each corner of the frame 1.

Each instrument V records the forces from 5 to 5000 N, and the tolerance of the measurement is from 0.01 to 2 N. The measurement of the force is sent by the scales to a constant and continuous PC 3, via an electrical conductor 3.2.

Scales V are electrically connected through the 3.2 conductor with the PC 3. Also, the scales V are powered by the PC through the conductor 3.2. The V scales measure the static and dynamic forces generated in the field V, between the frame 1 and the ground, and these data are fed continuously to the PC 3 through the guide 3.2. Scales V, if selected as an option, are generally installed at all points where the frame 1 touches the ground and continuously measure static and dynamic forces, and these data are fed continuously to the PC 3.

It is understandable that the support points of the frame must be so apart that the frame 1 due to the shock movements of the skier S does not overturn. The frame dimensions of the layout of the frame are: width from 80 to 350 cm, length from 25 to 200 cm. Height of frame 1 oz. of the receiving rod 1.2 is from 50 to 250 cm.

The track 1.2 can be designed either flat or in radius R from infinity to min. 50cm. If the track 1.2 is straight or manufactured with a large radius R, the elastics 1.5 are assumed to play a greater role than in the case where the track 1.2 is constructed in radius R. In the case that the track 1.2 is constructed in radius R, the skier S receives a similar response of the frame 1 , as in the real skiing track, because it also moves in the direction of the vertical.

The length of the track line 1.2 can range from 20 to 350 cm.

Depending on the mass-weight of the skier S, we select how much elastic 1.5 will be introduced to the 1.4 trolley. The number of elastic can be from 0 to 15 on each side (left and right). Pre-tense can be from 0 to 500% of elastic length.

In addition to the weight of skiing S, the number of elastic 1.5 also influences the choice of the track, snow. In the event that SW is selected for the southern snow, we have to mount more elastic 1.5 on cat 1.4 and vice versa.

The scales V, provided the frame is equipped with them, provide, through a pulse connection 3.2, a pulse to the PC in which SW converts them into a picture sent over the connection of the pulses 3.1 to the television 2 showing the movement and pulses of the ski S, transformed into a picture of skiing 2.2. In the event that we also cover the data of the V scales, we can produce a much more sophisticated SW program that gives a much more realistic picture of the actual skiing S.

Scales V may also be equipped with VC air or hydraulic cylinders that raise or lower the frame 1 in relation to the control of the VC cylinders. In the event that we have built-in VC cylinders that can be pneumatic or hydraulic, we can additionally modify or control the frame 1 via the SW installed in the PC 3, depending on the selected track and the difficulty of the line, which is written in SW-ru.

The VC cylinder stroke is from 5mm to 500mm. In the event that we have built-in pneumatic or hydraulic cylinders, the entire assembly must be equipped with a PM pressure storage tank, which ensures the necessary pressure of the medium, which is from 0.1 to 500bar, and a capacity ranging from 0.0001m3 / min to 20m3 / min , let it be for air, oil or some other medium. The pressure and capacity of the PM pressurized storage container are controlled via a PC 3 or soft wears loaded in PC 3, via electrical connections 3.2.

As an additional option, the installation of special pedals 1.4.2 on the trolley 1.4 fitted for the left and right legs of the skier S. The footers 1.4.2 are rotatably mounted in the middle with a socket 1.4.2.1 which allows the movement of the pedal 1.4.2 in the direction of the SN .

As a support of the feet 1.4.2, they can be placed under the feet 1.4.2, the spring 1.4.2.2, which are supported by the brackets 1.4.2.2.1, on the underside, and the upper one with the foot 1.4.2. Springs have the task of creating the reaction of the force given by the skier S in exercise. Under foot 1.4.2, sensors 1.4.2.4, which record movements of the pedal 1.4.2 in the direction of the PS, are placed. Extension 1.4.2.3, pedals 1.4.2, or its always different, the changing position against sensory 1.4.2.4, continuously provides information on the position of the pedal 1.4.2, the sensor 1.4.2.4. Sensor 1.4.2.4 can also be fused or unconnected-stepping. In the case of stepping-off, the distance between contact sensory 1.4.2.4 is from 0.2 to 5mm.

For even more sophisticated exercise or a more realistic feel, we can place the 1.4.2.5 weights on the feet 1.4.2, which record the forces of the mass and the pressure of the ski foot. Force signals and force change per unit of time are sent to PC 3, which, according to the selected SW, converts to a change in the image of skier 2.2 on screen 2.

Scale 1.4.2.5 records the forces from 5 to 5000 N, and the measurement tolerance is from 0.01 to 2 N. The measurement of the force is sent by the balance 1.4.2.5, fed to the PC 3.

The inclination of the feet 1.4.2 and the recording of the force of the foot pressure of the skier S, through the weighing instruments 1.4.2.5, give the data on the basis of which the SW can calculate and process this data as the correct or less correct turn in terms of the correct use of the ski bucket in the cutting technique. has the effect of accelerating the image of the skier 2.2 on the screen 2. This will result in a more correct learning of the skier S and, consequently, better results in relation to the selected route and conditions, which are set through PC 3 ..

Correct slope means: 1. enough slope on both pedals 2. parallel slope of pedals 3. correct distribution of pressure on the pedals

The trolley 1.4 is mounted on the track 1.2 via the four upper wheels 1.4.1 which are rotatably mounted on the axles 1.4.1.1 and via the two lower wheels 1.4.2 which are rotatably mounted on the axles 1.4.2.1.

The upper wheels 1.4.1 of the trolley 1.4 engage in the 1.2.1 belt, which is fixedly fixed to the track 1.2, and the lower wheels 1.4.2 engage the lower part of the track 1.2.

The upper wheels 1.4.1 are bombarded and made from an elastic polymer of a hardness of 50 to 400 Shorov that dampens vibrations and flows through the gutter 1.2.1 of the track 1.2.

The lower wheels 1.4.2 are, as a rule, cylindrical in shape and made of a similar material similar to that of the upper wheels 1.4.1.

The lower wheels 1.4.2 are screwed to the lower part of the trolley 1.4.3 via the axle 1.4.2.1 on which the nut is screwed, via a vertical groove, which is embedded in the lower part of the trolley 1.4.3. For this reason, the vertical displacements of the axle 1.4.2.1 can be adjusted, the height or consequently the axis of the axles 1.4.1.1 and 1.4.2.1 must be adjusted to achieve a close match between the upper wheels 1.4.1 and the lower wheels 1.4.2 on the track 1.2. Tight matching is important because of the feelings from the trolley 1.4, skier S. receives through his feet.

KT sensors may be installed on the track 1.2 at any time and in all known ways, therefore this is not the subject of this invention.

It is also not the object of this invention to construct a complete frame 1, which is, as a rule, assembled in such a way that it can be easily disassembled and transported by car. The mode of frame structure 1 is a known state of the art, and we use screws, sockets, etc.

Installation of elastic 1.5 is also a known state of the art and is not the subject of this invention. It is important, however, that the elastics 1.5 can be opened and locked on a trolley 1.4, in any number, which is provided from 1 to 15 elastics, not one side of the trolley 1.4. The number of elastic 1.5 and the preload elastic 1.5 is always equal to the left and right sides of the trolley 1.4 to obtain the symmetrical position of the unladen trolley 1.4.

Elastics 1.5 can also be pre-tensioned arbitrarily, which is enabled by known technical solutions that are not the subject of this invention. It is important, however, that it is anticipated before tensioning the elastic 15. From 0 to 500% of the elastic lengths 1.5.
