Training device for adjusting basketball shooting angle

The present invention relates to a training device, and more particularly to a training device for a pitching angle.

Basketball is a kind of ball game in which two teams participate and compare the scores of the two teams. The goal is achieved by putting the ball into the opponent's ball frame to score, or preventing the opponent from getting the ball or scoring.

In order to effectively put the ball into the ball frame, it is known that some scholars calculate the minimum incident angle Am that can enter the basket after considering the diameter of the ball frame and the diameter of the ball. The minimum incident angle Am is about 32 degrees, that is, when It is possible to enter the basket directly from the angle of incidence between 32 and 90 degrees without touching the ball frame at all. Referring to FIG. 1 , when the incident angle of the sphere 11 is lower than 32 degrees, the sphere 11 must touch the front edge or the trailing edge of the ball frame 12, and then the frame is ejected, so that the incident angle is larger. The more easily the ball is directly into the frame; on the other hand, in the actual case, the larger the incident angle, the more waste is applied to the vertical component of the sphere 10 on the sphere 10. Therefore, considering the saving of the pitcher's strength and the scoring rate, the inventor of the present invention proposed that when the pitcher throws the ball, the elevation angle of the shot is preferably 45° to 65°, and 58 degrees is the most. Good shots on the elevation.

In view of this, the inventors have conceived and studied more deeply, The training pitcher shot at the best elevation angle and finally invented a training device to adjust the basketball shooting angle.

The invention provides a training device for adjusting the shooting angle of a basketball shooting, the main purpose of which is to train the pitcher to shoot at an elevation angle higher than 45° to improve the shooting rate of the shooting.

In order to achieve the foregoing objective, the present invention provides a training device for adjusting the angle of the basketball shooting shot, which is used in conjunction with a ball. The training device includes: a ball frame, which is attached to a frame, and the frame system is disposed on the ground. a shot position, the height of the shot position is lower than the ball frame, so that the trajectory of the ball from the shot position toward the ball frame starting from a hand elevation angle and entering the ball frame is an ideal parabola, wherein the shot angle is an ideal parabola The system is disposed between the ball frame and the hand-carrying position, the obstruction unit includes at least one obstacle member, and each of the obstacle members has a top end portion at the top of each of the obstacle members, and the top end of each of the obstacle members The pedestal is higher than the spherical frame and the shot position, and lower than the ideal parabola; the surface passing through the spherical frame and parallel to the ground plane is a first reference surface, the center of the spherical frame and the top of each obstacle member The connecting line is an inclined line, and the angle between each inclined line and the first reference surface is an inclination angle, and the surface passing through the shooting position and parallel to the ground plane is a second reference surface, and the shooting position and each of the positions obstacle The line connecting the top end of the piece is an elevation line, and the angle between each of the elevation line and the second reference surface is an elevation angle, wherein each of the inclination angles and each of the elevation angles is less than 45°; thereby, the sphere is self-contained After the shot position is thrown toward the ball frame, the sphere It must pass over the upper side of the obstruction unit.

A preferred embodiment of the training device for adjusting the angle of the basketball shot is shown in Figures 2 to 4, which is used in conjunction with a ball 71, which is preferably a basketball. The training device includes: a ball frame 20, a hand position 30, and a blocking unit 40, wherein the ball frame 20 is disposed on a frame body 21, the frame body 21 is disposed on the ground, and the frame body 21 is provided The ball 71 guides back to one of the ball guiding slanting plates 22 of the hand position 30. The height of the ball frame 20 from the ground is 1 meter to 3.05 meters. Preferably, the ball frame 20 is 3.05 meters away from the surface. The diameter of the ball frame 20 can be changed to a different size according to actual needs; the handle position 30 is lower than the height of the ball frame 20, and the hand position 30 is when the average person stands on the side of the frame body 21. At about 15 centimeters above the front of the forehead, a sign may be placed at the hand position 30 to inform the user that the hand position 30 is present, or a seat 31 is provided at the hand position 30 for the user to sit directly On the seat 31, the height of the seat 31 can be adjusted according to the height of the user. The height is adjusted to be about 15 cm in front of the forehead to the shot position 30. After the shot position 30 and the center of the ball frame 20 are projected to the ground, the length of the connection is between 1 and 6 meters. For the average adult, considering that the distance from the free throw line of the basketball to the bottom line is 5.8 meters, the preferred length is 5.8 meters and the other side. In the case of a user who is less energetic, such as a child, a closer distance, such as 1 meter, is suitable; the ball 71 is moved from the hand position 30 toward the ball frame 20 at a hand elevation angle SA. The trajectory that initially enters the ball frame 20 is an ideal parabola P, wherein the hand elevation angle SA is greater than 45°; more specifically, between 45° and 65°; preferably, the hand elevation angle SA is The obstruction unit 40 is disposed between the ball frame 20 and the hand position 30. In this embodiment, the obstruction unit 40 is disposed on the frame body 21, and may be directly disposed on the ground. The obstruction unit 40 includes at least one obstacle member 41. In this embodiment, the number of the obstruction members 41 is one, and the highest portion has a top end portion 411, and the top end portion 411 of the obstruction unit 41 has a cross bar shape. a structure, and extending from the two ends of the crossbar to the bottom and spanning on two sides of the frame body 21, the top end portion 411 of the obstacle member 41 is higher than the ball frame 20 and the hand position 30, and the obstacle member 41 The height can be adjusted to match the position of the shot 30.

Referring to FIG. 3 again, the surface passing through the ball frame 20 and parallel to the ground plane is a first reference surface F1, and the center of the ball frame 20 and the top end portion 411 of the obstacle member 41 are one. The inclined line L1, the angle between the inclined line L1 and the first reference plane F1 is an inclination angle A1, the surface passing through the shot position 30 and parallel to the ground plane is a second reference plane F2, the shot position 30 and the obstacle The line connecting the top end portion 411 of the member 41 is an elevation line L2, the angle between the elevation line L2 and the second reference surface F2 is an elevation angle A2, and the sphere 71 is connected to the ball frame 20 from the shot position 30. The line is an ideal parabola P, which is ideally thrown The angle between the object line P and the second reference plane F2 defines a hand elevation angle SA, and the hand elevation angle SA must be greater than the angle of inclination A1 and the elevation angle A2, so that the sphere trajectory of the sphere 71 is along the ideal parabola P. After the ball frame 20 is thrown out, the goal rate can be surely increased. Accordingly, the ideal parabola P must be formed by the angle of the hand elevation angle SA being greater than 45°, and the angle of inclination A1 and the elevation angle A2 are configured. The sphere trajectory after the shot position 30 is thrown coincides with the ideal parabola P; in other words, if the angle of the shot elevation angle SA is less than 45°, or the inclination angle A1 and the elevation angle A2, the sphere trajectory of the sphere 71 cannot be ideal. Parabola P coincides, and the scoring rate will decrease accordingly. It can be seen that regardless of whether the user is tall or low, the angle of the exit angle SA is greater than 45°, and the inclination A1 and the elevation angle A2 are both acceptable. Improve the scoring rate of the shot; Thereby, after the sphere 71 is ejected from the shot position 30 toward the bezel 20, the sphere 71 must pass over the upper side of the obstruction unit 40.

The above description is the main components of the embodiment of the present invention and their configuration description. For the use and function of the embodiment of the present invention, please refer to FIG. 3 and FIG. 2 . Generally, according to the present invention, a seat 31 is disposed on one side of the frame 21 , and the user sits on the seat. The chair 31 has a handle position 30 about 15 cm above the front of the forehead, and the user uses the force of the upper limb to throw the ball 71 toward the ball frame 20, and the obstruction unit 40 is disposed between the shot position 30 and the ball frame 20. Therefore, the user must raise the elevation angle of the shot to above 45°, otherwise the sphere 71 will be blocked by the obstruction unit 40 and cannot enter the frame; on the other hand, in order to save energy, the user will try to shoot at a lower elevation angle. With this, reach Train the pitcher to shoot at an elevation angle of 45°.

Please refer to Figure 4 in conjunction with Figure 3. Since the height and the arm of the user are not the same, and the user usually saves the effort, the shot will be shot at a lower angle of elevation SA. The effect of the training, the seat 31 can be adjusted in height in accordance with the height of the user. As shown in FIG. 4, the seat 31 can be raised for a user who is short or has a short arm length; The height of the obstruction unit 40 can also be adjusted together; in addition, regardless of whether the height of the user is high or low, the angle of elevation SA of the hand must be greater than 45° to truly achieve the goal of increasing the scoring rate.

Please refer to FIG. 5 , which is another embodiment of the present invention, wherein the obstruction unit 40 has three obstacle members 41 , and the top end portion 411 of each of the obstacle members 41 is higher than the ball frame 20 and the The shooting position 30 is lower than the ideal parabola P, and one of the obstacle members 41 is disposed on the axis of the ideal parabola P, and the other two obstacle members 41 are disposed on two sides of the axis of the ideal parabola P, thereby using It is possible to more clearly check whether the parabola of the sphere 71 that he has cast conforms to the ideal parabola P.

In addition, the obstruction unit 40 of the present invention may also exist in other forms. For example, as shown in FIG. 6, the obstruction unit 40 is a barrier plate 42 which is a transparent flat plate structure and is erected on the frame body. The guide ball slanting plate 22 of 21 can avoid affecting the user's line of sight, so that the user can completely see the ball frame 20. In addition, for users who are less energetic in their arms, they can also be implemented by standing or pitching and pitching as shown in the figure. When the height is hindered by the unit 40, the user who is less energetic in the arm can also use the present invention for training.

From the above, it is known that the present invention truly conforms to "industrial availability," "novelty," and "progressiveness", and submits an invention patent application in accordance with the law, praying for review and early granting of a patent, and it is truly sensible.
