[0048] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A first embodiment of the ball returning device for training of the present invention comprises a supporting unit 1, a ball returning unit 2, and a limiting unit 3.

[0049] The support unit 1 includes two brackets 11 extending along a first axis Z and spaced apart along a second axis X, and a base 12 connected to one end of the brackets 11 and suitable for standing on a court (not shown). Each of the brackets 11 has a plurality of through holes 111 arranged along the first axis Z. The second axis X is substantially perpendicular to the first axis Z.

[0050] The ball return unit 2 is pivotally disposed between the brackets 11 and forms a first angle θ1 with the first axis Z, and can pitch and swing relative to the bracket 11 with the second axis X as the center, and includes an elastic-plastic member 4 (such as Figure 6) and a frame 22 surrounding the periphery of the plate 21. In this embodiment, the plate 21 has a support layer 211 and an elastic layer 212 stacked on the support layer 211. The support layer 211 can be wood or reinforced glass, and is used to support the elastic layer 212. The elastic layer 212 is made of high-hardness foam. The frame 22 has two screw holes 221 formed on both sides. The first angle θ1 is less than 90 degrees.

[0051] 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 rod 311 can rotatably pass through the corresponding through hole 111 of the respective bracket 11, and is screwed into the respective screw hole 221 of the frame 22. The bolt head 312 is pressed against the respective bracket 11.

[0052] See also Figure 1 , Figure 4 and Figure 5 When adjusting and scaling the first angle θ1 of the ball return unit 2, it is only necessary to unscrew the first bolt 31, turn the ball return unit 2 to the required angle, and then screw in the first bolt 31 so that the screw 311 of the first bolt 31 is screwed into the screw hole 221 of the frame 22. After the bolt head 312 is pressed against the bracket 11 to lock the frame 22, the ball return unit 2 can be stabilized at the default first angle θ1.

[0053] When adjusting the height of the ball return unit 2, it is only necessary to remove the first bolt 31, and then adjust the ball return unit 2 to a predetermined height along the first axis Z direction, so that the screw hole 221 of the frame 22 is aligned with the corresponding through hole 111 of the bracket 11, and then, screw in the first bolt 31, so that the screw 311 of the first bolt 31 passes through the through hole 111 of the bracket 11 and is screwed into the screw hole 221 of the frame 22, so that the ball return unit 2 can be fixed at a default height.

[0054] See also Figure 3 , Figure 4 and Figure 6 Taking the ball 4 as a badminton, during training, the present invention can be placed in front of the player, and when the player hits the ball 4 to the elastic layer 212 of the plate 21, the ball 4 can be rebounded by the elasticity of the elastic layer 212. At this time, the player can catch the ball 4 rebounded by the plate 21 and hit the ball 4 to the elastic layer 212 of the plate 21 again. This cycle is repeated until the player misses the ball 4 and the ball 4 falls to the ground.

[0055] Since the first angle θ1 between the plate 21 and the first axis Z determines the height of the ball 4's rebound, the player can adjust the plate 21 to a suitable angle according to training requirements. Figure 6 As shown in FIG. 1 , when the first angle θ1 is larger, the height of the ball 4 rebounding is higher, and the flight path of the ball 4 will fly upward from the plate 21, thereby repeatedly performing smash training, such as Figure 7 As shown, when the first angle θ1 is smaller, the rebound height of the ball 4 is lower, and the flight path of the ball 4 is closer to a straight line, thereby repeatedly performing forehand or backhand shot training and flat shot training.

[0056] In addition, 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 rebounds. Therefore, as the player hits the ball 4 at different angles and with different forces, the rebounding ball 4 will have different angles and landing points. Therefore, in addition to training the skills of catching the ball, it can also train the player's on-the-spot reaction.

[0057] See also Figure 4 and Figure 8 When the ball return device of the present invention is to be stored, it is only necessary to adjust the first angle θ1 of the ball return unit 2 to 0 degrees, so that the ball return unit 2 can be parallel to the bracket 11, thereby reducing the space occupied by the whole and improving the space efficiency when stored.

[0058] See also Fig. 9 and Fig.10 , is a second embodiment of the present invention, which is substantially the same as the first embodiment, and also includes the support unit 1, the ball return unit 2, and the limit unit 3, with the difference being:

[0059] The limiting unit 3 further includes two swing arms 32 pivotally mounted on the bracket 11, and two second bolts 33 mounted on the frame 22 and spaced apart along the second axis X. Each of the swing arms 32 extends along a length direction L, and has a plurality of through holes 321 arranged along the length direction L. Each of the second bolts 33 can be detachably inserted into the corresponding through hole 321 of the respective swing arm 32.

[0060] Thus, when the ball return unit 2 is stabilized at the default first angle θ1, the swing arm 32 can be rotated until the corresponding through hole 321 of the swing arm 32 is aligned with the second bolt 33 fixed on the frame 22, and the ball return unit 2 can be supported by the swing arm 32, and the angle of the ball return unit 2 can be limited by the second bolt 33. Thus, during the player's hitting process, the first angle θ1 of the plate 21 is maintained, and there will be no angle deviation due to excessive force of the ball 4 (not shown) hitting the plate 21.

[0061] It is worth noting that, since the swing arm 32 has a limiting function, the first bolt 31 is not limited to being a bolt, and in other variations of this embodiment, it may also be a latch.

[0062] See also Figure 11 to Figure 14 , is a third embodiment of the present invention, which is substantially the same as the first embodiment, and also includes the support unit 1, the ball return unit 2, and the limit unit 3, with the difference being:

[0063] The support unit 1 also includes two elastic groups 13 that can be compressed. Each of the brackets 11 has a first set 112 and a second set 113 that can be movably fitted on the first set 112 along the first axis Z direction. The first set 112 has a plurality of positioning holes 114 arranged along the first axis Z direction. The second set 113 is inserted into the first set 112 and has a screw hole 115 formed at one end and a broken hole 116. Each of the elastic groups 13 is installed in the second set 113 and has a locking portion 131 that passes through the broken hole 116 and can be elastically locked in the corresponding positioning hole 114.

[0064] The ball return unit 2 further includes a back frame 23 connected to the plate 21, and two linkage members 24 connected to the back frame 23 and pivotally connected to the bracket 11. Each linkage member 24 has a connecting section 241 connected to the back frame 23, and two ear seats 243 opposite to the connecting section 241 and defining a groove 242. The groove 242 is for the respective bracket 11 to pass through.

[0065] The screw rod 311 of each first bolt 31 of the limiting unit 3 can rotatably pass through the ear seat 243 of the respective linkage 24 along the second axis X direction and be screwed into the screw hole 115 of the respective bracket 11 , and the bolt head 312 of each first bolt 31 is pressed against the corresponding ear seat 243 .

[0066] Thus, when adjusting the first angle θ1 of the ball return unit 2, it is also only necessary to unscrew the first bolt 31 and pull the ball return unit 2 to drive the back frame 23 and the connecting member 24, so that it can be rotated to the required first angle θ1 around the second axis X, and then, the first bolt 31 is screwed in so that the screw 311 of the first bolt 31 is screwed into the screw hole 115 of the bracket 11, and after the bolt head 312 is pressed against the ear seat 243 to lock the connecting member 24, the ball return unit 2 can be stabilized at the default first angle θ1.

[0067] When adjusting the height of the ball return unit 2, it is only necessary to squeeze the abutting portion 131 of the elastic group 13 out of the positioning hole 114 of the first set 112 of the bracket 11, so that the second set 113 can be retracted and extended, and the ball return unit 2 can be driven to rise and fall to a predetermined height along the first axis Z direction. Then, the elastic group 13 is released, so that the abutting portion 131 of the elastic group 13 is abutted against the corresponding positioning hole 114, so that the ball return unit 2 can be fixed at a default height.

[0068] It should be noted that when adjusting the height of the ball return unit 2, it is not limited to the method of telescoping the second kit 113. In other variations of this embodiment, the height of the bracket 11 can also be changed by hydraulic, pneumatic or electric power. Since those with general knowledge in this field can infer the expanded details based on the above description, they will not be explained in detail.

[0069] See also Fig.15 , Fig.16 and Fig.17 , is a fourth embodiment of the present invention, which is substantially the same as the first embodiment, and also includes the support unit 1, the ball return unit 2, and the limit unit 3, with the difference being:

[0070] The support unit 1 further includes a connecting member 16 connected to the other end of the bracket 11 and extending along the second axis X direction, and a rotating group 17 .

[0071] The rotating group 17 has a first switching member 171 pivoted to the bracket 11 and swinging left and right around the first axis Z, and two second switching members 172 installed on the ball return unit 2 and spaced apart along the second axis X. The first switching member 171 and the connecting member 16 form a second scalable angle θ2. The second switching member 172 is pivoted to the first switching member 171 and swings relative to the first switching member 171 around the second axis X, and forms the first angle θ1 with the first axis Z.

[0072] The limiting unit 3 includes two pitch limiting groups 35 installed on the first switching member 171 and spaced apart along the second axis X direction, and a deflection limiting group 36 installed on the first switching member 171 and adjacent to one of the pitch limiting groups 35 .

[0073] Each of the pitch limiter groups 35 is used to scale the first angle θ1, and has a first linkage member 351 connected to the respective second reversing member 172 and extending and retracting along a third axis Y. Each of the pitch limiter groups 35 can be powered by hydraulic pressure, pneumatic pressure or electric power. In this embodiment, each of the pitch limiter groups 35 is an electric motor. Since it is a generally commercially available product, no further explanation is given here. The third axis Y is substantially perpendicular to the first axis Z and the second axis X.

[0074] The deflection limiter 36 is used to scale the second angle θ2, and has a second linkage 361 connected to the connection member 16 and extending and retracting along the third axis Y. The deflection limiter 36 can be powered by hydraulic pressure, pneumatic pressure or electric power. In this embodiment, the deflection limiter 36 is an electric motor, which is a commonly available product and will not be described in detail.

[0075] Thus, when adjusting the first angle θ1 of the ball return unit 2, it is only necessary to control the extension and retraction of the first connecting member 351 of the pitch limit group 35 through a switch (not shown), so that the ball return unit 2 can be pushed to rotate around the second axis X through the pivotal relationship between the second switching member 172 and the first switching member 171. After rotating to the required first angle θ1, the pitch limit group 35 abutting between the second switching member 172 and the first switching member 171 can stabilize the ball return unit 2 at the default first angle θ1.

[0076] In addition, in addition to being able to adjust the first angle θ1 of the ball return unit 2, the present embodiment can also adjust the second angle θ2 of the ball return unit 2. During adjustment, it is also only necessary to control the extension and retraction of the second connecting member 361 of the deflection limit group 36 through a switch (not shown). The first reversing member 171 and the connecting member 16 can be used to push the first reversing member 171 together with the second reversing member 172 and the ball return unit 2 to rotate around the first axis Z. After rotating to the required second angle θ2, the deflection limit group 36 that abuts against the first reversing member 171 and the connecting member 16 can stabilize the ball return unit 2 at the default second angle θ2.

[0077] It should be noted that the pitch limit group 35 and the yaw limit group 36 are not limited to being controlled by switches. In other variations of this embodiment, they may also be controlled by switches. Fig.18As shown, the limit unit 3 further includes a remote controller 37. Thus, the remote controller 37 can control the pitch limit group 35 to drive the ball return unit 2, or control the deflection limit group 36 to drive the ball return unit 2 by wireless remote control.

[0078] See also Fig.19 , is a fifth embodiment of the present invention, which, like the first embodiment, comprises the support unit 1, the ball return unit 2, and the limit unit 3, but differs in that:

[0079] The support unit 1 includes a back frame 14 suitable for being mounted on a wall 5, and a bracket 15 connected to the back frame 14 and forming a third angle θ3 with the back frame 14. The bracket 15 extends along a first axis Z. Preferably, the third angle θ3 is substantially 90 degrees, and of course, a different third angle θ3 can be used according to the site or usage requirements.

[0080] The limiting unit 3 includes a plurality of limiting members 34 connected to the bracket 15. The limiting members 34 are spaced apart along the first axis Z direction and extend along a second axis (not shown). In this embodiment, the limiting member 34 is a pyramid.

[0081] When in use, the ball return unit 2 only needs to be pressed against the back frame 14 and the bracket 15, and the ball return unit 2 can be stabilized between the back frame 14 and the bracket 15 by blocking and limiting the ball return unit 2 through one of the stoppers 34. When one end of the ball return unit 2 presses against the stopper 34 closer to the back frame 14, the other end of the ball return unit 2 is further away from the bracket 15, and the first angle θ1 between the ball return unit 2 and the bracket 15 is larger. On the contrary, when one end of the ball return unit 2 presses against the stopper 34 farther away from the back frame 14, the other end of the ball return unit 2 is closer to the bracket 15, and the first angle θ1 between the ball return unit 2 and the bracket 15 is smaller. In this way, the first angle θ1 of the ball return unit 2 can also be maintained during the player's hitting process.

[0082] It should be noted that the ball return unit 2 is not limited to abutting against the back frame 14. In other variations of this embodiment, the back frame 14 may also abut against the wall 5 when it is shorter or is only a connecting medium. In addition, the back frame 14 is not limited to being connected to the wall 5 by the back frame 14. In other variations of this embodiment, the back plate 14 may be omitted. Fig. 20 As shown, the ball return unit 2 is stably located between the wall 5 and the bracket 15 .

[0083] It should be noted that the ball 4 is not limited to badminton. In other variations of this embodiment, it can also be a billiard, a tennis ball, a football, etc., but is not limited to this.

[0084] Through the above description, the advantages of the above embodiments can be summarized as follows:

[0085] 1. The present invention has high mobility and can be used for self-simulation training without any restriction on the use time and without the need for an opponent, thereby improving the convenience and practicality of use.

[0086] 2. More importantly, the present invention can adjust the angle and height of the ball return unit 2 as required by training, so that the rebounded ball 4 can have different ball paths, and as long as the ball 4 does not fall to the ground, the ball 4 can be continuously returned.

[0087] 3. Furthermore, in addition to being able to continuously catch the rebounding ball 4, the player can also train the real-time reaction when catching the ball, the ball control strength, and the return angle when the rebound angle and the rebound distance of the ball 4 are not fixed, thereby improving the diversity of training effects, including agility, muscle endurance, stability, ball control feel, and the realism of simulated playing.

[0088] The above description is only a preferred embodiment of the present invention, but it is not intended to limit the scope of the present invention. Any person familiar with this technology can make further improvements and changes on this basis without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims of this application.
