Description

The simulator belongs to devices for teaching the game of volleyball and is intended to improve the technique of striking movement, in particular, the technique of secondary strikes, which allows to increase the accuracy of attacking strikes.

Volleyball is a non-contact, combination sport where each player has a strict specialization on the court. The most important qualities for volleyball players are jumping ability for the ability to rise high above the net, reaction, coordination, physical strength for the effective performance of attacking attacks.

Ball proficiency is a very important aspect of volleyball. For most players, constant practice is required to develop ball skills that require a high level of skill and coordination of volleyball players. Therefore, it is advisable for them to use mechanical means of delivery to practice an attack hit in volleyball.

Offensive strike is one of the most important aspects of volleyball, and one of the most difficult skills that athletes need to master. It assumes appropriate coordination on the part of the supplying player and implies that the ball be thrown by the player upward, so that he begins his downward arc almost vertically and is in close proximity to the net, but is not accessible to defenders.

A variety of simulators have been proposed for practicing an attack strike in volleyball.

Known training devices that hold the ball at a selected height for practicing an attack hit, for example, a simulator, which is a frame that is supported by one player. Using the device, the ball is manually set to the desired height above the playing surface so that the player can practice hitting the ball.

The device consists of an S-shaped bar and a support post attached to it and supported by a player or coach. The sliding bar allows you to hit the ball and move it. After each hit, the ball is set back into the device manually. [US Patent No. 5660395 of 08/26. 1997].

The disadvantage of this device is that after each hit the ball must be installed in the device manually.

There are simulators in which a volleyball ball is tied on two sides to practice attacking strikes: it is secured with cables on each side and lifted using a rack above the net for training strikes [for example, US patent No. 7041016 of 09.05. 2006].

The disadvantage of this simulator is that each ball must be fixed with cables.

It is most advisable to practice an attacking strike using a hoisting device for supplying balls, in which they are placed in series and are automatically fed to strike. Such devices do not need to be loaded after each hit, and the ball trajectory during training is closer to the trajectory during a real hit.

Some designs known in the art include a hopper that connects to the ball feed device.

Both of these devices are mounted using a vertical support or stand. The vertical stand goes up from the weighted base or support located on the playing surface near the net, and can be both on wheels and without them.

Closest to the technical nature of the claimed invention is a simulator, consisting of a device for practicing strikes [US patent No. 12/928879 of 22.12. 2012].

The simulator is equipped with wheels, so it can be quickly moved to the training venue. Once the training device is installed, it is fixed to prevent it from rolling away. The lifting rack is directed upward from the base of the simulator to secure the elements of the ball-feeding device. The rack has a crank handle for vertical adjustment of extendable rack elements so that you can reach the correct height for the game.

In a bunker located in the upper part of the rack, several volleyballs are placed alternately, which, under the action of gravity, move down an inclined ramp in the upper part of the frame leading from the bunker towards the outlet.

When the balls move down the ramp, they are distributed by a mechanical lever that separates the balls so that they fall to the place of the impact one by one. Holders pointing down receive balls falling from the ramp and temporarily hold them to strike. One holder is locked in one position and the other is movable.

The starting point from which the ball is hit is the point between these holders. As soon as the ball is hit, the next ball will be released by the distribution mechanism, and the ball automatically falls into position between the holders for the next hit.

The dumping ramp and switchgear reliably ensure a consistent flow of balls “one after another”, and uninterruptedly prevent interference and unwanted interruptions.

The speed of change of volleyballs, the ability to produce “one by one” strong and high-quality kicks at balls at a height that adjusts to the growth of each volleyball player greatly simplifies the process of training an attacking strike.

However, it has a significant drawback - this simulator is suitable for training with balls of only a certain standard size, for other size balls, other designs must be used.

The objective of the invention is the creation of a simulator for training and improving the technique of striking in volleyball, which allows the most diverse range of balls to be used in the training process and to adjust the simulator parameters to a specific height in the shortest possible time.

The problem is solved in that the post of the simulator 3 (Fig. 1) is installed on the base 1 so that the winch 4 is at the top. To fix the vertical pillar 3, it is fastened to the base 1 with a wing bolt 2. A frame 9 consisting of parallel tubes is put on the vertical pillar 3, having at the beginning a platform for fastening the basket for balls 10 and at its end a platform for guiding them to the grips balls 17. The basket for balls 10 is attached to the frame 9 using rods 8 and wing bolts 7.

To change the height of the center of the ball in the device for capturing balls, it is necessary to use a winch 4.

The balls are thrown into the basket one by one. They roll down to the automatic ball limiter 12, after which they fall into the ball grabs 17. After removing the ball from the ball grabs, the next ball falls into its place.

In the device for capturing balls 17 (Fig. 2), the distance between the grippers can be changed by twisting or unscrewing the wing nuts 21 and 22 located on the adjusting pin 14.

When unscrewing the wing nut 22 and tightening the wing nut 21, the angle of inclination of the regulator 19 changes, on which the guides of the ball grips 16 are fixed. With the position of the wing nuts 21 and 22 changing, the distance between the ball grips decreases (for balls of smaller diameter) or increase (for balls of larger diameter). The springs 15 serve to dampen the vibration that is transmitted from the ball grabs 17 to the frame 9.

A general view of the simulator for training and improving the technique of striking in volleyball is shown in FIG. 3.

Designations of the positions indicated in FIG. 1 and 2 are presented in table. one.

Examples of specific performance. These simulators are most widely used in youth sports schools, schools of the Olympic reserve, specialized sports clubs and sections.

Their use can significantly reduce the training time for an attacking hit in volleyball.

Previously, when these devices were not available, the training process took quite a long time, it was necessary to work out the blow on the descending ball, which was sent by the sparring partner. With the advent of the presented mechanical device, the training time was reduced by 3-4 times due to the fact that the ball is stationary.

The use of the inventive simulator allows, in comparison with the known simulators, to reduce the training time for an attacking hit in volleyball, since it is applied in a stationary state, to use the most diverse range of balls in the training process and to adjust the simulator parameters to a certain height in the shortest possible time.
