Description

The present invention relates to the field of sports and, in particular, can be used to train athletes - skiers, biathletes and athletes of other similar sports.

A well-known training system for skiers, biathletes, including fixing the time of the ski run with a stopwatch and subsequent comparison with known indicators (see Fin A.I. The system for training skiers-skiers, M .: FiS, 1978, 345 pp.).

There is a well-known system of training cyclists “Racing for the Leader”, in which the leader for the cyclist is a motorcycle, while the rider must sit straight to create the effect of “aerodynamic shadow” behind him (see the website http://veiorama.ru/giossary/motorpace .phtmi).

However, in the well-known leader-motorcyclist system, it is impossible to provide a rational training for the athlete-cyclist, since the leader-motorcyclist does not regulate the speed of the athlete and does not take into account his individual characteristics.

In addition, the well-known training system cannot be used for other sports, such as skiers, biathletes, etc.

The aim of the present invention is to achieve a technical result in expanding the list of sports in which a controlled and regulated training system is provided, for example, skiers and biathletes, whose travel route takes place in the field.

The indicated technical result for the device is ensured by the fact that in a known system comprising a leader, it is proposed to install a light projection unit at each of the ski track sections viewed from one point, including a light source, to which an end of the flexible light guide is connected through the shutter, the second end of which oriented to the athlete’s movement path and fixed by springs in the center of the frame, three rings are installed on the outer surface of the outer end of the light guide, with inner sleep troughs the snakes, the first two of which include the edges of two eccentrics, and the groove of the third rests on the edge of the contour of the route section cut out in the template, while the axis of rotation of the eccentrics lie in the same axis as the fiber, but in mutually perpendicular planes, also in each block of light of projection it is proposed to introduce a signal receiver, respectively, of the beginning and end of work, with each receiver configured to receive a signal from the transmitter, the previous block of optical projection in the direction of movement of the athlete, and each before The sensor is configured to send a signal to the receiver of the next unit in the direction of the athlete’s movement, it is proposed to connect the eccentrics via gears to an engine with a speed controller, and connect the obturator to a common or autonomous engine.

The specified technical result for the method is ensured by preliminarily splitting the ski slope into separate sections viewed from one point, the sections on which light projection units are installed, while the neighboring ones are connected to each other by telecommunication or wire connection.

The system for training skiers is illustrated with graphic materials. Figure 1 shows a typical ski route, Figure 2 shows a fragment of the construction of the light projection block, Figure 3 shows a view of the external end of the fiber fixed to the frame, Figure 4 shows an example of the profile of the movement profile of the external end of the fiber in the template, Figure 5 presents the design of the drive control of the eccentrics, Fig.6 is a block diagram of the connection between the blocks of light projection, Fig.7 shows the construction of the location of the eccentric for the straight section, Fig.8 shows the electrical diagram of the connection ni nodes and blocks.

29 is an electronic key for controlling the operation of a light source, electric motors, and a transmitter.

The light source 1, which is used as a matrix of LEDs with a parabolic reflector 2 (not shown) or a laser emitter, to which the end of the flexible light guide 4 is connected through the obturator 3 with color filters 4. The outer end 5 of the light guide 4 is oriented to the ski run and fixed by springs 6 in the frame 7 so that in a free state it is located in its center.

On the outer surface of the outer end of the flexible fiber 4 is placed three rings 8, 9, 10 with inner grooves 11 on their outer side.

The grooves 11 of the first two rings 8, 9 include the edges of the flat eccentrics 12, 13, and the groove 11 of the third ring 10 contacts the edge of the contour 14 of the section of the ski run cut out in the template 15.

The latter was done in order to ensure smooth movement of the light spot along the route due to possible geometric inaccuracies in the manufacture of eccentrics 12, 13, to exclude fluctuations in the output end of the fiber 4 from the wind, vibrations during operation of electric motors, and other factors.

The axis of rotation of the eccentrics 12, 13 are parallel and each of them lies respectively in the horizontal and vertical planes with the longitudinal axis of the flexible fiber 4, see Figure 2.

The shapes and patterns of rotation of the eccentric (s) 12, 13 are calculated based on the profile and shape of the sections of the ski run, the height of the light projection source, and other factors.

For example, for rectilinear and horizontal sections A, B, see Figure 1, the eccentric 12 is horizontal and stationary, and the second eccentric 13 rotates and has the shape of a star with pointed rays and rounded sides, see Fig. 7.

For the arcuate sections C, B, E, see Figure 1, the eccentrics 12, 13 are star-shaped with four rays, one of whose sides is oval and the other a straight line.

The length of the large eccentric 12 is equal to the deviation of the output end of the optical fiber 4 along the horizontal axis, and its width is equal to the length of the short eccentric 13, which, in turn, is equal to the deviation of the end of the optical fiber 4 along the vertical axis. In this case, the contour 14 for moving the end of the optical fiber 4 for this section will have the form shown in FIG. 4.

The eccentrics 12, 13 are connected to the electric motor 18 through autonomous gears 16, 17, and the obturator 3 is connected to the electric motor 20 through the gearbox 19, see Fig. 8.

Each electric motor 16, 17 has speed controllers 21, 22 (not shown in the drawings). The outer end of the fiber 4 is fastened to the springs 6 through the fastening ring 23 mounted on it, see Figure 2.

For fastening the outer and inner parts of the template 15, externally mounted brackets 24 are used, which do not interfere with the movement of the outer end 5 of the optical fiber 4 along the contour 14, see FIG. 6.

Each light projection source includes a receiver 25 and a transmitter 26. In this case, the receivers 25 are configured to receive a signal of the same frequency from the transmitter 26 of the previous light projection unit, and the transmitters 26 transmit a signal of the same frequency to the receivers 25 of the next projection skier of the light projection block.

All light projection units have autonomous power sources 27, permanently connected to the receivers 25, see Fig. 8. The receivers 25 are in standby mode and turn on when receiving an external signal from a neighboring unit. The obturator 3 contains color filters that provide good visibility of the color spot in the snow.

A switch 28 is installed at the end point of circuit 14 of the template 15 corresponding to the athlete’s exit from the track. It turns on when the cam 12 moves horizontally along the end 5 of the optical fiber 4 and, turning on the transmitter 26, sends a signal to the receiver 25 of the next skier , block light projection and through an electronic key 29 disconnects the functional blocks from the power source 24 after completion of work.

The system for training skiers works as follows.

Previously, the ski run is divided into such autonomous regions, each of which could be viewed from one point, see Fig. 1.

The sections of the route have a different shape (straight line, oval, semicircle, etc.) and a different profile (descent, ascent). Considering these factors, at each section of the route, at a height (on a lighting pole or on a tree), a light projection block is installed, whose output end 5 of the light guide 4 is moved in space by one or two rotating eccentrics 12, 13, the shape of which, as well as the shape cut out in the template 15 of the contour 14, provides a continuous movement of the colored spot along the ski track.

The speed of movement of the light spot is adjusted using the unit for adjusting the speed of rotation of the engine 16 in its power circuit, and the flash frequency of the light spot through the unit (not shown) for adjusting the speed of rotation of the shutter 3.

At the initial stage of training, the assistant coach bypasses all sources of light projection and sets the required speed of movement of the end face 5 of the light guide 4, i.e. sets the speed of movement of the light spot, taking into account the profile of the track and the individual capabilities of the skier (s).

At the time of start, the trainer turns on the first light projection block, the light spot of which begins to move along the first section of the ski run. In this case, the eccentrics 12, 13 jointly start moving the outer end 5 of the light guide 4 from the starting point of the contour 14 of the ski run section and bring it to the end point of the contour 14 of the first stretch, turn on the transmitter 23, which transmits a signal to the next block in the direction of the skier light projection.

This signal is received by its receiver 25, which through an electronic key 28 connects the power source 27 to the light source 1, to the motors 16, 17, controlling the rotation of the eccentrics 12, 13 and the shutter 3, see Fig. 8.

The eccentrics 12, 13, driven by the gearboxes 14, 15, deflect the outer end of the flexible fiber 4 and project the light spot in front of the skier onto the trajectory of the track. In this case, the springs 6 try to hold them and return the outer end 5 of the fiber 4 to the initial state, in the center of the frame 7. Thus, they tightly press it to the eccentrics 12, 13, additionally ensuring its reliable movement along the contour 14, see Figure 4.

In this case, the output end face 5 of the light guide 4, through the groove 11 of the ring 10 worn on it, rests on the edge of the contour 14 of the section of the ski track in the template 15 and, sliding along it, projects the light spot exactly along the ski track.

The shape of each of the eccentrics 12, 13 is made in such a way as to ensure the movement of the end of the fiber 4 along the track of the athlete in this area. It is calculated by alternately deflecting the end face 5 of the light guide 4 to the extreme horizontal and vertical points of the line of the route and fixing them on the template 15.

At the end point of the contour 14 of the template 15, corresponding to the athlete’s exit from the track section, a contact switch 28 is installed, see FIGS. 4, 8, upon which an eccentric 12 of longitudinal movement runs into. In this case, the transmitter 23 is turned on, which sends a signal to the receiver 22 of the next, in the direction of the skier, light projection unit and by means of the electronic key 29 disconnects the power from all functional units.

The speed of movement of the light spot along the track is set so that it is slightly more than the speed of the skier, due to his physical capabilities. In this case, the movement of the light spot makes it seem to “stretch” behind it, thereby mobilizing its physical resources for higher results.

After “mastering” this speed by the athlete, it is again slightly increased, forcing him to “pull himself back” to a new speed line again. And so to the maximum possible for this athlete limit.

The claimed system can also be used to train biathletes. In this case, the entire ski run is divided into two stages - before and after the shooting range. The light beam, having reached the shooting range, stops, and after the end of the shooting, the athlete turns on the first light projection block of the second stage section and continues to move.

The flexible light guide 4 can be woven from individual fiber optic cores or a sectional pipe with articulated cylinders, with internal mirrored or white walls partially entering into each other, which allows it to bend under the influence of eccentrics 12, 13 due to the displacement of the pipes relative to each other.

The claimed system is intended mainly for training skiers, biathletes and athletes of other similar sports, the Olympic reserve and potential candidates for world records.

The claimed system and the method implementing it are new, previously unknown, which indicates their compliance with the patentability criterion - novelty.

The system can be manufactured at any instrument-making or radio engineering enterprise of medium technological equipment and installed on any ski track, which indicates its compliance with the patentability criterion - industrial applicability.
