FIELD OF THE INVENTION The invention relates to a device for training skiers, skis, naturally skiers.

A device for training a shooter is known, which contains a base with bases in which skis are placed.

This device allows cross-country skiers to train. The only disadvantage of it is the impossibility of working out the technique for overcoming the sharp bending of the slope, since the base is an infinite canvas, installed with the possibility of changing the angle of inclination to the horizon.

In order to ensure the possibility of working out the technique of overcoming the sharp bending of the slope, the proposed device is equipped with a safety device for the skier and a means for braking the skis, containing a hook attached under the ski loading platform, spring loaded shchki placed along the base of the hook along the axis, and the base consists of several the hinge-interconnected parts mounted under the angle of one to the other, while the axis of the means for braking skis is located under the base in the place of one of its hinge joints to cooperate with the hook and schtokom. The safety device for the skier contains a guide

attached to the base, and along with, connected to the rail by means of a rope and a shock absorber.

FIG. 1 shows the proposed device, side view; in fig. 2 is the same, view along arrow A in FIG. 1: in FIG. 3 is the same; the section along BB in FIG. 2; in fig. 4 is the same section along the line B-B in FIG. 2; in fig. 5 is the same; the section along YY in FIG. four; in fig. 6 same view

along arrow D in FIG. 3; in fig. 7, 8, and 9 - various athlete positions in the exercise.

The device comprises a base 1 with grooves 2, consisting of several parts 3, 4, 5 pivotally interconnected, mounted at an angle to one another, and mounted on the frame 6, skis 7 placed in the slots of the base, means for braking skis containing hook 8 (fig. 5), fixed

under the load platform of the ski, the rod 9 is positioned at the hook base 10 along the ski, and the axis I (Fig. 2 and 3), located under the base in the place of one of its hinged parts, for example

4 and 5, with the ability to interact with the hook and rod. The axis I is attached to the rods 12 installed in the base with the possibility of movement in the limiters 13, and is spring-loaded. The springs 14 are placed on the shafts between the axis Y and the restraints 13.

A safety device for a skier contains a guide 15 mounted on frame 6, and from 16, connected to the guide through rope 17 and a shock absorber 18. Soft supports 19 and 20 for the torso of the athlete and skis are installed on frame 6 to soften the blows.

Use the device as follows.

The athlete on skis becomes on part 3 of base 1, secures it to 16 from the body and, gliding along the base, moves to its accelerating part 4, helping the movement of the arms while supporting the handrails 21. When approaching the hinge connection of the accelerating part 4 the base and the trigger part 5, the athlete makes movements similar to the full-scale when overcoming the bend of the slope during a descent directly, i.e., he pulls the ski weights up (jumping) with a corresponding sharp forward inclination of the hull (dive) (see Fig. 7, 8, 9). At the same time, the axis 11 enters the cavity 22 formed by the ski 7 and the hook 8 (Fig. 8), which limits the height of the jump, and rests against the rod 9 of the hook. After receiving information about the push of the rod 9, the athlete will perform the movement described. Then, the transition to the descent from part 5 of the base, the spring-loaded rod 9 interacts with the axis 11, moving it relative to the stops 13 and deforming the spring 14. Soft stops 19 and 20 and the shock absorber 18 of the safety device serve for the final stop of the athlete.
