Description

ball return device for training

The invention relates to a ball returning device, in particular to a ball returning device for training.

Ball games require not only sufficient endurance and explosive power, but also good skills. Therefore, in order to improve their skills, professional players not only have coaches to guide them, but also need to practice repeatedly.

Taking badminton as an example, there are currently two training methods for players:

1. Cooperate with coaches or other players to practice with other players: Since two players are playing against each other, there will be different ball paths under different thinking and different situations, so the ball path changes the most. However, the training time will be limited by the time of the accompanying players or coaches, and the mobility is low.

2. Serving from the ball machine: Players who can cooperate with training can train at any time, and the ball path can be changed in many ways according to the set mode. However, the ball machine cannot return the shuttlecock. Therefore, each ball fired can only be returned once by the player, and a large amount of shuttlecocks will be consumed in the training process. Train the player's on-the-spot reaction when receiving the ball.

Therefore, the object of the present invention is to provide a ball returning device for training that has unlimited use time, does not require opponent's self-simulation training, and can improve the player's on-the-spot response.

Therefore, the ball returning device for training of the present invention includes a support unit, a ball returning unit, and a limiting unit.

The supporting unit includes at least one bracket.

The ball returning unit is arranged on the at least one bracket, and forms a scalable first included angle with a first axis, and includes an elastic-plastic plate suitable for bouncing a ball.

The limiting unit is formed between the supporting unit and the ball returning unit, and is used for stabilizing the ball returning unit at the first included angle.

The effect of the present invention is that: through the angle-adjustable and elastic-plastic return unit, the player can not only continuously return the rebounding ball, but also when the rebounding angle and rebounding distance of the ball are not fixed, Train the immediate reaction when catching the ball, ball control strength, and return angle, and improve the diversity of training effects, including agility, muscle endurance, stability, ball control feel, and the fidelity of simulated playing.

Referring to FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , a first embodiment of the ball returning device for training of the present invention includes a support unit 1 , a ball returning unit 2 , and a position limiting unit 3 .

The support unit 1 includes two brackets 11 extending along a first axis Z direction and spaced apart along a second axis X direction, and a bracket 11 connected to one end of the brackets 11 and suitable for standing on a court (not shown). Base12. Each bracket 11 has a plurality of through holes 111 arranged along the first axis Z direction. The second axis X is substantially perpendicular to the first axis Z.

The ball returning unit 2 is pivotally arranged between the brackets 11, and forms a first angle θ1 with the first axis Z, and can pitch and swing relative to the brackets 11 with the second axis X as the center, and includes a An elastic-plastic plate 21 suitable for bouncing a ball 4 (as shown in FIG. 6 ), and a frame 22 around the periphery of the plate 21 . In this embodiment, the plate 21 has a supporting layer 211 and an elastic layer 212 stacked on the supporting layer 211 . The supporting layer 211 can be wood or strengthened glass for supporting the elastic layer 212 . The elastic layer 212 is made of high hardness foam. The frame 22 has two screw holes 221 formed on two sides. The first included angle θ1 is less than 90 degrees.

The limiting unit 3 is installed between the supporting unit 1 and the ball returning unit 2 and includes two first bolts 31 . Each of the first bolts 31 has a screw rod 311 and a bolt head 312 opposite to the screw rod 311 . The screw rods 311 are rotatably passed through the corresponding through holes 111 of the respective brackets 11 , and are screwed into the respective screw holes 221 of the frame 22 . The bolt head 312 is pressed against the respective bracket 11 .

Referring to Figure 1, Figure 4 and Figure 5, when adjusting and scaling the first included angle θ1 of the ball returning unit 2, it is only necessary to unscrew the first bolts 31 and move the ball returning unit 2 to the desired angle , and then screw into the first bolts 31, so that the screw rods 311 of the first bolts 31 are screwed into the screw holes 221 of the frame 22, until the bolt heads 312 press against the brackets 11 and press the frame After 22°, the ball returning unit 2 can be stabilized at the preset first included angle θ1.

When adjusting the height of the ball returning unit 2, it is only necessary to remove the first bolts 31, and then adjust the ball returning unit 2 to a predetermined height along the first axis Z direction, so that the screw holes of the frame 22 221 is aligned with the corresponding through holes 111 of the brackets 11, and then screwed into the first bolts 31, so that the screw rods 311 of the first bolts 31 pass through the through holes 111 of the brackets 11, and are screwed into the The screw holes 221 of the frame 22 can fix the ball returning unit 2 at a preset height.

Referring to Fig. 3, Fig. 4 and Fig. 6, taking the ball part 4 as a shuttlecock as an example, during training, only the present invention is placed in front of the player, and the ball part 4 can be hit by the player to the board part 21 When the elastic layer 212 of the elastic layer 212 is used, the ball 4 is rebounded through the elastic-plasticity of the elastic layer 212. At this time, the player can return the ball 4 bounced by the plate 21, and hit the ball 4 again to The elastic layer 212 of the panel 21 . So it goes round and round until the player misses the ball 4 and the ball 4 falls to the ground.

Since the first included angle θ1 between the plate 21 and the first axis Z will determine the rebound height of the ball 4, players can adjust the plate 21 to an appropriate angle according to training needs, for example, As shown in Figure 6, when the first included angle θ1 is larger, the height of the rebound of the ball 4 is higher, and the flight path of the ball 4 will be lifted upward by the plate 21, thereby, it can be repeated. The training of smashing the ball, as shown in Figure 7, when the first included angle θ1 is smaller, the height of the rebound of the ball part 4 is lower, and the flight path of the ball part 4 will be closer to a straight line, thereby, positive and negative can be repeated. Backhand or backhand pumping training, flat ball training.

In addition, because the angle and force at which the ball 4 hits the plate 21 will affect the angle and distance of the ball 4 when it bounces, therefore, the angle at which the ball 4 hits the ball 4 is different. , power is different, the ball part 4 of rebound just has different angle changes, and landing point also can change, therefore, except the skill when catching the ball can be trained, also can train the player's on-the-spot reaction.

Referring to Fig. 4 and Fig. 8, when the ball returning device of the present invention is to be accommodated, it is only necessary to adjust the first included angle θ1=0 degree of the ball returning unit 2, so that the ball returning unit 2 can be parallel to the brackets 11, And reduce the space occupied by the whole, and improve the space efficiency when storing.

Each swing arm 32 extends along a length direction L, and has a plurality of through holes 321 arranged along the length direction L. As shown in FIG. Each of the second bolts 33 is detachably inserted in the corresponding through hole 321 of the respective swing arm 32 .

In this way, when the ball returning unit 2 is stabilized at the preset first angle θ1, the swing arms 32 can be rotated until the corresponding through holes 321 of the swing arms 32 and the second bolts fixed on the frame 22 33, the ball returning unit 2 can be supported by the swing arms 32, and the angle of the ball returning unit 2 can be limited by the second bolts 33. In this way, further in the process of the player hitting the ball, the first included angle θ1 of the plate 21 is maintained, and there will be no angular deviation due to the excessive force of the ball 4 (not shown) hitting the plate 21 situation.

It is worth noting that, since the swing arms 32 have a position-limiting function, the first bolts 31 are not limited to be bolts, and may also be a pin in other variations of this embodiment.

Thereby, when adjusting the first included angle θ1 of the ball returning unit 2, it is also only necessary to unscrew the first bolts 31, and pull the ball returning unit 2 to drive the back frame 23 and the linking parts 24. It can be rotated around the second axis X to the required first included angle θ1, and then screwed into the first bolts 31 so that the screw rods 311 of the first bolts 31 are screwed to the brackets 11 After the screw holes 115 press the bolt heads 312 against the lugs 243 and press the linkages 24, the ball return unit 2 can be stabilized at the preset first included angle θ1.

When adjusting the height of the ball returning unit 2, it is only necessary to force the locking portions 131 of the elastic groups 13 to disengage from the positioning holes 114 of the first set 112 of the bracket 11, and then the second sets 113 can be stretched and stretched, and drive The ball returning unit 2 is raised and lowered to a predetermined height along the first axis Z direction, and then the elastic groups 13 are released, so that the locking portions 131 of the elastic groups 13 are locked against the corresponding positioning holes 114, and can be fixed. The ball returning unit 2 is at a preset height.

It should be noted that when adjusting the height of the ball returning unit 2, it is not limited to the way of expanding and contracting the second sleeves 113. In other variations of this embodiment, it can also be adjusted by means of hydraulic pressure, air pressure or electric power. Changing the heights of the brackets 11 is not further explained because those skilled in the art can deduce the expanded details based on the above description.

Referring to Figure 15, Figure 16 and Figure 17, it is a fourth embodiment of the present invention, which is roughly the same as the first embodiment, and also includes the support unit 1, the ball returning unit 2, and the limiting unit 3, the difference in:
