Abstract

The invention makes it possible to increase the effectiveness of training by simulating real conditions. The device comprises movable skis 22 connected by cable 24 with blocks 25 and 18 mounted on an inclined base. The block 18 is connected via a spring 19 and a shock absorber 15 to the pivot bar 12. The bar carries a shaft 14, made in the form of an unequal two-armed lever. The short arm of the pole is connected by a cable with a latch with a retainer mounted on the base. The device has a means for insuring the athlete including a cable 4 with branched arms. The node branch is mounted on the dorsal side of the athlete's sa. The branches of the cable 4 are connected in opposite directions with the base through the blocks 7 and the springs 6 and between themselves by the cable 10. The cable 10 encloses the movable block 11 mounted on the base before skiing. The device allows, when turning the skis, to charge the bar with the pole and, when going in the other direction, to imitate the slope of the pole from the interaction with the athlete. 1 hp ff, 5 ill.

Description

This invention relates to training sports equipment.

The aim of the invention is to increase the effectiveness of training by simulating real conditions,

Fig, 1 shows the device (right side), a general view; in fig. 2 - the same, top view; in fig. 3 - the same, side view; in fig. 4 is the same, view along arrow A in FIG. one; in fig. 5 is a section BB in FIG. 3

The device contains an inclined base 1 for placing skis, a vertical wall 2, on the hook 3 of which a cable 4 is fixed to means of an insurance comprising 5, springs 6 by means of which the branches TDjeca 4 are separated to the sides and thrown over blocks 7. connected to the base . The springs 6 are tensioned and secured between the strips 8 by means of fingers 9.,

The branches of the cable 4 are interconnected by the ends of the other cable 10, thrown over the block 11, pivotally mounted on the base 1. On the base 1, the rods 12. are rotatably mounted in the base plane and the mobility in the plane 13 perpendicular to it is supported on the wheels 13. At the ends of the rods 12, the shafts 14 are pivotally mounted. The rods 12 are connected to shock absorbers 15, thrown over the blocks 16. mounted on the base, and then thrown over the blocks 17, also mounted on the base, and connected to the blocks in 18 (fig. 6). which are also connected to the springs 19, the other ends connected to the ears 20. The cages of the blocks 16 are aligned with the stops 21. On the skis 22, the trolleys 23. The trolleys 23 mounted on the rear of the joint venture SL

after that

Kah skis, connected by cables 24 (Fig. 6 and 1), thrown over the blocks 25, installed in the cage 26, and then through the blocks 18, with pins attached to the base. Trolleys 23 mounted on the toes of the skis are connected by cables 27 with ears 28 (Fig. 3). Each rod 12 (Fig. 4) is pivotally mounted on a column 29 mounted on the base. Each shaft 14 with a short shoulder is connected by a cable 30 with a latch 31 and fingers 32 fixed in the grooves of the rod 12 and connected to a spring 33. The latches 31 interact with clamps 34 fixed on the base. Each trolley 23 (FIG. 5) has cheeks 35 connected to collars 36, bolts 37 interconnected through gasket 38, on ski 22 and connected to cable 24 (rear carts) or cable 27 (front carts) through bolt 39 .

The simulator is used as follows. Before starting the training session, the athlete adjusts the suspension system by its height by hanging the cable 4 on the corresponding hook 3 and pulls the springs b, fixing them with fingers 9 between the strips 8 having a number of holes. Then, in special boots, it is mounted on skis with the help of fasteners attached to them and fastens on the 5th of the suspension system, after that you can take up the ski poles and start training. By a muscular effort, similar to the effort applied by a skier when making a turn, the athlete diverts skis to one side or the other, while the cant of them, i.e. inclination relative to the ground plane 1. When the skis are moved, the cables 24, drawn out, move the block 18, with the clip of which the spring 19 is connected, counteracting the athlete's effort applied to the skis to such an extent that training without special stress and with the necessary dynamics continues the process lead skis. At a certain moment, the roller of the rear cart 23 of the outer ski will meet with the rod 12 (Fig. 6), turning towards it, since the moving case of the 18t block is not at the end of the shock absorber 15. After this, the movement of the outer ski is possible with the turn of the rod 12, pulling the absorber 15. The rod 12 rotates until the shaft 14 comes into contact with the tensioned branch of the suspension cable 4, while it deflects, pulling the latch 31. which passes by the latch 34. This ends one turn. The athlete to move to the next turn balances the forces on both branches of the cable 4, while the cable

10, connecting them, there is no longer a stretched branch, as well as another. This will allow the shaft 14 to be upright, and the latch 31 will come into contact with

a latch 34 and locking the rod 12 in an charged position. At the same time, the athlete continues to move to the next turn. On the other half of the simulator, all the above phases of rotation

0 are repeated. In addition, to simulate the passage of the flag, in accordance with modern slalom technique, it is necessary to tilt the shaft by hand. When the charged shaft is tilted through the cable 30, there is no sweat at the slot 31, removing it from contact with the latch 34, unlocks the rod 12, which, under the action of the shock absorber 15, which is in the tensioned position, will turn around the column 29, leaning on the wheel 13, as far as the stop 21. The shaft 14 will move along an arc past the trainee, imitating the relative movement of the shaft-skier performed on a real slope.

5The presence on the trainer of poles, making movement relative to the skier, and the peculiarities of the connection of skis with the base with cables and springs ensures the working out of the basic elements of the technique

0 slalom: accompanied by turning and passing flags, while imitating the effect on the training centrifugal forces, both attached to the skis, and to the skier himself. That, before touching the flagpole, for his

5 tilt, it is at rest, provides a safe workout, although after it is released, the speed of the shaft can reach the real relative speed of the shaft-skier up to 60 km / h. The owner of the simulator will also increase the interest of the general physical classes when installing the simulator in the gym of enterprises and organizations. The advantages of the simulator are obvious when it is used as an attraction, as well as in the case of restoration of articular mobility after injuries and disorders of the vestibular apparatus after a long bed rest treatment or after flying in weightlessness.
