Abstract

The invention makes it possible to increase the effectiveness of training and learning the exercises on the rings by providing realistic conditions when using a longi for insurance. The device contains pivotally connected at an angle to one another the cantilever beams. The lower parts of the beams are connected to the telescopic arms by means of hollow bushings. The outer parts of the levers are spring-loaded to the inner ones and carry a lock on the ends attached to the shock absorbers. Cables bearing rings, passed through the holes in the bushings. The support of the beams is made suspended and spring-loaded to the base. To ensure that the levers return to their original position, the last gears are connected with spring-loaded levers. When an athlete performs repetitive rotations, the levers make a 360 ° synchronous turn, which eliminates the overlap of flexible tons of lugs with cables. 1 hp ff, 3 ill.

Description

The invention relates to simulators for athletes and is intended to learn exercises on rings when they repeatedly perform rotational and interchangeable movements both in one and in several (in different) directions.

The purpose of the invention is to increase the effectiveness of training by providing real-world conditions.

FIG. 1 shows the device, the initial position J in FIG. 2 is a view along arrow A in FIG. one; in fig. 3 t fixture, levers carrying lounges occupy the lower position.

The fixture contains a support 2 suspended on the rope 1, made :: in the form of cantilever beams hinged at an angle to one another.

3. On the lower sections of the beams 3, the upper parts of the figured sleeves 4 are fastened, on which the levers are fitted by means of bearings 5. The levers 5 are made telescopic. The outer part of the levers 5, the slide blocks 6, is connected to the inner side by means of adjustable elastic elements 7. The latter are adjusted within predetermined limits by means of clamps 8, which set the limits of displacement of the sliders 6 with respect to the levers 5. The levers 5 are rigidly connected to gears 9, which are located in meshed with gear wheels 10 rigidly mounted on axles 11, the latter are inserted into the arms 3 rotatably, and the ends of spring-loaded levers 12 are fixed at their ends. Rotating bushings 13 are mounted at the ends of the arms 12 C.

The latter are connected by elastic dampers - jams 14, covering blocks 15, located on consoles 3. Other ends of shock absorbers 14 are fixed on consoles 3. In the latter, guide rollers 16 are installed. In the lower parts of bushings 4, clamps 17 are fitted with two the guide rollers 18 and 19. The rollers 16, 18 and 19 provide the vertical direction of the cables 20, passed through the sleeves 4 (Fig. 1 and 2).

With the ends of the sliders 6, the arms 21 are articulated by means of rotating sleeves 22 with spreaders 23. The latter include adjustable belts 24 and shock absorbers 25. The shock absorbers 25 are connected to the ramp 26, which has the possibility of biaxial rotation (Fig. 3).

Gymnastic rings 27 are suspended from the ends of the cables 20. The other ends of the cables 20 are connected by rotates 28 to ropes 29, passed through guide blocks 30, 31 and 32, and through steel chains 33 connected to a fixed hook 34 of the base. Rope 1 is passed through guide blocks 35 and 36 and, via a shock absorber 37 and a steel chain 38, is hooked onto a fixed hook 39 of the base.

The training apparatus for gymnasts is used as follows.

After an individual determination of the initial length of the belts 24, shock absorbers 25, 7 and 37, as well as the height of the suspension device, the gymnast puts the insurance on s - longe 26 and seizes the rings 27. The starting position of the gymnast on the screen corresponds to his highest position (for example, ). At this time, the operator (trainer) lowers the end of the rope 1 down, lift the fixture up to a predetermined height and fixes it with one of the links of the chain 38 for the hook 39. At the same time, the cana 1 should not be pulled so that the shock absorbers 14, 25 and 37. In this position, the slide blocks 6 together and the levers 5 are turned inside and upwards (in the direction of the suspension bracket of the Spreader 23 device, the shock absorbers 25 and the belts 24 in the initial position are not stressed (in Fig. 1 the belts 24 are released).

In the course of a gymnast performing rotational movements in a vertical plane, under the influence of the weight of his body, stretch 23, levers 21, sliders 6 and levers 5 begin to rotate. The latter rotate with gears 9, from which gears 10 and axes 11 are rotated. As a result, the levers 12 and the sleeves located at their ends begin to rotate around the latter.

13. Levers 12, turning 180 on, move in an inclined plane from top to bottom (from cable 1 to cables 20), the elastic shock absorbers 14 pull. Sliders 6, rotating in an inclined plane, move along with the levers 5 giva shock absorbers 7, 14, 25 and 37. When levers 5 reach 6 together with sliders, they turn to 180e (at their maximum lunge down) adjustable arms 3 are as close as possible to each other, and length 26 is below the rings 27 (Fig. 3 nat chickpeas shock absorbers 25 and belts 24). In this case, the inclined position of the levers 5 contributes to the fact that stretching 23, lowering, bend around (bypass) the cables 20, to avoid overlapping with them, which contributes to the stretching of the cables beyond the limits of the cables 20. The inclination of the consoles also ensures that the weight of the gymnast 180 turn In this position, the rope 1 and the shock absorbers 7, 14, 25 and 37 are maximally tensioned, which facilitates the movement of the tool down the cables 20, passed through the guide rollers 16, 18 and 19.

When the gymnast moves up by inertia, his body's weight on the device (simulator) and its nodes gradually decrease, and when the gymnast's body inertia is affected and the tension of the shock absorbers 7 and 14 continues, all rotational movements in the simulator continue, i.e. the fixture returns to its original position. Levers 5 make a 360 turn.

In any rotational movement of the gymnast in any direction, the couplings 22. and 28 rotate, which, together with the possibility of biaxial rotation of the lounge 26, eliminates the twisting of the stretch 23.

The device provides a gymnast to perform repetitive rotations and a combination of various motor-rotational actions both in one (only forward or only backward) and in various (forward and backward) directions, i.e., the twisting of the stretches and their overlapping with cables and, therefore, eliminating winding of stretch on the body of the gymnast. In addition, since the sum of the kinetic energy of the gymnast's movement and the tension force of the shock absorbers are used, there is no need for a special propeller to return the device (levers) to its original position.
