Description

The utility model relates to sports training devices of the shock type, designed primarily for training and improving the technique of shock movement in various sports, such as baseball, soccer, hockey, golf, tennis, volleyball.

A device is known for training the kick technique of athletes, comprising a frame and a spring-loaded rod with an elastic impact object mounted in it in a tubular guide (see AS USSR No. 387720, IPC А63В 69/00, publ. 19.11.74). The tubular guide is fixed in the bed movably, and one of its ends is spring-loaded.

However, the reciprocating mechanism of the device allows the object of impact (for example, the ball) to move in a straight line, while the hand (or lower leg) moves in an arc. Different trajectories of the ball and arm lead to a violation of the biomechanical conditions of the collision, which affects the quality of the workout. The device is not effective enough for practicing the impact technique also because restrictions on the degree of freedom entail high requirements for the accuracy of the impact movement. This is unacceptable when training beginner athletes due to their lack of motor skill in shock movement.

A device for training tennis players containing a pendulum handle mounted on a rack with the possibility of rotation around the axes of the pendulum and equipped with a rotating element at the free end that simulates a tennis ball with an elastic elastic element mounted for rotation when hit by a racket. After hitting the ball, the handle returns to its original position automatically. The device can be adjusted in height. The pendulum can rotate and stop in vertical or horizontal positions (see EP1728536, IPC A61B 69/00).

However, the device does not provide training for all types of shock movements in tennis, moreover, it does not allow practicing shock movements in other sports. The device also has a small amplitude of motion of the target and a long period of post-shock oscillations.

Closest to the proposed solution is a device for training and improving the technique of striking in volleyball (see RF patent No. 2301696, IPC A63B 69/00, publ. 2007.06.27). The device comprises a supporting frame, a ball, a unit for returning the ball to its original position, containing a rod, one end of which

mounted on the frame with the ability to provide at least two degrees of freedom, and the second end is connected to the ball, elastic stretching, one end connected to the frame, and the second to the rod, the rod travel limiter in the form of a trapezoidal shape, fixed between the ends of the supporting frame, shock absorbers, located in the extreme positions of the stroke of the rod.

However, this device allows you to work out only one type of impact from one position, which is not enough for complex training and development of skills. In addition, the design does not provide long-term operation, since in case of an incorrect impact (which is not uncommon among beginner athletes), the rod contacts the stroke limiter hard. This can lead to a breakdown of both the rod itself and its attachment to the frame.

The task is to create a device for training and improving the impact, which allows you to work out all possible blows (ball feed, side kicks left and right, hit the ball when it is near the ground, kicks with the ball spin), which has a reliable design and a long service life.

The technical result is the possibility of practicing all types of punches with a hand, foot, bat, club, tennis racket or something else on the target due to the use of special fasteners that allow the simulator to be mounted at different heights and at different angles, increasing the simulator's reliability by distributing the shock load between the elements fixing the rod and eliminating the possibility of hard contacts between the parts of the simulator.

The specified technical result is achieved by the fact that the device for training shock movements of athletes contains a supporting frame made with the possibility of fixing it on a support, a target, a rod, one end of which is fixed to the frame, and the second is connected to the target, an elastic stretch connected at one end to the frame and the second end connected to the rod, the limiter of the stroke of the rod attached to the frame, shock absorbers located in the extreme positions of the stroke of the rod. According to the decision, the supporting frame is made with the possibility of its rotation relative to the support in the horizontal plane with subsequent fixation in the selected position.

The support comprises a rotational mechanism of the supporting frame, made in the form of a ring having the possibility of vertical movement relative to the support. The carrier frame contains stops made with the possibility of tight contact with the ring.

The device contains guides for stretching, made in the form of rollers fixed around the perimeter of the supporting frame.

The rod is equipped with roller stops, and the stroke limiter of the rod is made in the form of two, opposite each other, arcuate elements between which the roller stops can move.

The travel stop and the frame are connected by a subframe having a shape that allows the rod to move freely with the target between the shock absorbers.

The best version of the simulator.

The device comprises a frame 5 made of steel pipes of rectangular cross section. Frame 5 consists of a front 17, rear 18, transverse 19 and upper 20 beams, while the rear 18 and upper 20 beams are connected at right angles. The transverse beam 19 is located in the Central part of the rear beam 18, perpendicular to it and the upper beam and is designed to better fix the frame 5 on the ring 15. The front beam 17 is parallel to the rear 18 and is connected to the upper beam 20 using an inclined beam 21, located at an angle of 45 °. The device also includes a movable rod 1, the upper end of which is pivotally fixed using the axis 2 in the eyes 3 of the rod 4, which is placed in the housing 22. The housing 22 has two inserts 24 of material with cushioning properties, such as rubber, located at both opposite ends. The rod 4 is made with the possibility of rotation around its axis and small displacements along the axis due to the presence of inserts 24. Due to this structural embodiment, the rod 1 acquires an additional degree of freedom along and around the axis of the rod. The housing 22 of the rod 4 is mounted on the supporting frame 5 using the bracket 23. The bracket 23 is made of two parallel plates, having the form of isosceles of right-angled triangles, the right angles of which are welded to the housing 22, and others are welded to the frame 5 at the points of attachment of the beam 21 to the beams 17 and 20. Between the plates of the bracket 23, guide rollers are located 7. At the lower end of the front beam 17, a shock absorber 11 of the rod travel limiter is placed, which is a double folded package of several layers of rubber bands of different lengths. The edges of the shock absorber package 11 are fastened together by a bracket, which is attached to the beam so that in the initial position the rod was located vertically parallel to the front beam. A similar shock absorber 11 is made on the upper beam of the frame so that in the extreme position the rod 1 is horizontally parallel to the upper beam. An additional 7 sec. Roller is fixed on the front beam

using the bracket 25. In the initial position, the rod 1 is located vertically and pressed against the shock absorber 11 on the front beam using a brace 8 attached at one end to the rod (with the formation of a right angle in the initial position) passing through the guide rollers 7 and attached at the other end to the element tension 13. The tension element 13 is attached to the bracket of the shock absorber 11 located on the upper beam 20. The rear 18 and transverse 19 beams are connected by their midpoints and are equipped with semicircular stops 26 at the ends, made with the possibility of raft oh landing ring 15. The ring 15 is fixed on a cruciform frame 27, provided with anchorages 6 for placement at the front wall 16 or at any height. The ring 15 and the stops 26 are tightly interconnected using a clamp, which is a rod with a thread 28, fixed in the center of the cruciform frame - 27 and passing through a hole made in the mounting point of the transverse 19 and rear 18 beams, while screwed on the threaded rod 28 a nut 29 provided with handle levers 30. The frame 5 can be mounted on the mounting ring 15 at any angle. The rod 1 is equipped with stops 9, which are two rollers located in the initial position in the horizontal plane. Inside the frame 5, guides 10 for roller stops 9 are installed, made in the form of two circular arcs arranged in parallel, connected by ends to the front and upper beams. The guides 10 limit the oscillation of the rod in the transverse direction. A fixture 14 for securing the target 12 is located at the lower end of the rod 1. In the case of using a soccer ball, the fixture for securing the target is a platform 31 with a base 32 rigidly attached to the rod 1 at a right angle. The lower end of the rear beam 18 is connected to the guides 10 by means of a subframe 33, bent so that the rod 1 with the ball 12 can freely move from one shock absorber 11 to another. The insert 24 of the housing 22 of the rod 4 is designed to prevent oscillations (excessive vibration) after hitting the rod 1 with the target 12 about the shock absorbers of the limiter of the rod 11.

Work on the device as follows.

First, the fastening ring 15 is installed at the required height with the help of fasteners 6. Then, at the required angle, the supporting frame 5 is mounted, pressing it firmly against the ring 15 with the stops 26 using the rod 28 with nut 29. In the initial state, the pendulum in the form of a rod 1 is fixed near the front shock absorber 11 system of rollers 7 with a stretch 8 (elastic rubber cord-shock absorber). Since the target moves after an impact along an arc with a radius equal to the length of the rod, the smallest effort to the target to bring it out of its rest state must be applied along

tangent to an arc. Any other direction of impact movement of a racket, bat, club, arm or leg will be associated with great effort, which in turn will immediately feel the athlete, i.e. will receive information about the correctness of the blow and will be required to make adjustments on the next attempt. To adjust the effort to remove the target from the resting state, the tension of the stretch 8 is preloaded using element 13. If the target 12 was hit incorrectly, then forces arise that tend to rotate the rod 1 around its own axis and destroy its fastening to the frame 5. These forces are perceived by the roller stops 9, preventing unwanted movements of the rod 1. The athlete takes a position corresponding to the phase of the strike, with support standing or without support - in a jump. The impact on the target. The target, having received a significant charge of kinetic energy (momentum) and acceleration after impact, easily overcomes the stretch tension, moves along an arc of radius equal to the length of the rod 1, freely passes through the subframe 33 and collides with a shock absorber 11 mounted on the upper beam 20. Faced with shock absorber, the target loses speed to zero, and due to the tension force of the stretch the ball returns to its original position. Having exhausted inertial energy for 3-4 reciprocating oscillations (of the order of 1-1.5 sec), the target calms down in its initial position, abutting against the front shock absorber. The device is ready for use again. If necessary, change the position to practice other types of impact, loosen the nut 29 on the rod 28 and rotate the frame 5 until the target 12 is in the desired position, after which the nut is tightened again. If necessary, adjust the height of the position of the device by moving vertically a cruciform frame 27 with a ring 15 fixed to it.

This device allows in practice to implement training in shock movements and from the very beginning of training to begin to form not only the kinematic and rhythmic structures of shock movement, but more importantly - dynamic structures that form the basis of the entire shock movement. It allows you to practice not only the supply of the ball, but also side impacts both on the left and on the right. The device allows you to receive urgent information about the correctness of the strike.
