Description

Standard action shooting machine in narrow space

Technical Field

This patent belongs to the sports apparatus field, concretely relates to basketball shooting machine.

Background

Basketball sports are enjoyed by more and more people worldwide due to their entertainment, resistance, groupware, low requirements for the number of people and the field.

The basic motion of basketball is shooting, the front view of the standard backboard is shown in figure 1, the backboard is 1.05 m high and 1.8 m wide, the lower edge is 2.9 m from the ground, the diameter of the rim is 0.45 m, and the rim is 3.05 m from the ground. The correct shooting posture of 12 yards is that 12 yards jump or have a posture of jumping, the big arm is horizontal, and is ninety degrees with the truck, the forearm is perpendicular, becomes 90 degrees with the big arm, the palm holds in the palm, in the in-process that the ball rises, personally submits 45 ~ 50 degrees contained angles with the horizontal plane and stirs the basketball to the upper front for the basketball is the parabola, and the internal rotation flight is with great angle entering basket. The side view of the standard shooting action is shown in figure 2, wherein the backboard has the thickness of 0.03 meter, the height of 1.05 meter, the lower edge of 2.9 meters from the ground, the diameter of the basket is 0.45 meter, the distance from the ground is 3.05 meters, the height of a shooter is 1.7 meters, the arm length of the shooter is 0.6 meter, the basketball shooting device stands at the position of 12 yards, the distance from the center of the basket is 4.6 meters, the hand angle of the standard shooting action is about 50 degrees, the maximum height of the flight track of the basketball is 3.75 meters, and the height of an indoor shooting machine is 2.5 meters.

However, in practice, there are several problems as follows:

1. even if the ordinary basketball shooters know the action essentials, the basketball is easily shot towards the direction of the basketball hoop by themselves due to the fact that the backboard and the basketball hoop are attracted in the front direction, and therefore, the basketball cannot touch the basketball hoop due to the fact that the height of the basketball is not high enough, or even if the basketball touches the basketball hoop, the shooting angle of the basketball flying towards the basketball hoop is too small due to the fact that the shooting angle of the basketball is too small, and the basketball jumps out after touching the basketball hoop.

2. When children shoot the basket, the basket is too high and is not proportional to the size, so that the children are difficult to shoot the basket, or the children are easy to strengthen the wrong habit of forcefully shooting the ball towards the basket.

3. Shooting a basketball by using standard actions at 12-position opposite to a basket with the height of 3.05 meters, not considering air resistance, wherein the flight track of the basketball is a parabola, the maximum flight track of the basketball is 3.75 meters, then the radius of the standard basketball is 0.123 meter, the required space height is 3.873 meters, and the shooting cannot be practiced in a common house room because the net height in the common house room is only about 2.61 meters.

4. Shooting at outdoor standard basketball court, after the shooting, need run to pick up the basketball usually, consume physical power, vigor, interest and time for the shooting frequency reduces, and standard shooting action is difficult fixed and intensive, is difficult for forming muscle memory.

5. The standard basket is 3.05 meters high, the horizontal distance of 12 yards from the center of the basket is 4.6 meters, the ratio of the two is 0.66, while the current game hall has a shooting machine, the basket is 1.6 meters high, the shooting horizontal distance is 1.8 meters, the ratio of the two is 0.89, obviously, the shooting horizontal distance is shorter than the height of the basket. More seriously, if the standard basket with the height of 3.05 meters is suitable for most people with the height of about 1.7 meters, the basket of the shooting machine in the game hall with the height of 1.6 meters is suitable for children with the height of about 0.89 meters and is not suitable for most adults according to the proportional calculation. The shooting machine is used for shooting a basket, is just recreational and cannot be used as a tool for practicing shooting.

Detailed Description

1) The bottom cross arm support and the two bottom horizontal supports form a base of the shooting machine together, and the distance between the two bottom horizontal supports is determined according to the principle that the distance between the two bottom horizontal supports is as short as possible on the premise that the shooting action is not hindered to be completed, but the shooting machine cannot topple to the side surface under the impact of a basketball or a human body;

2) when the basketball shooting net cloth is fixed by the movable buckle, when the basketball does not roll down from the ball leaking hole, the movable buckle is loosened, so that the basketball shooting net cloth is loosened, and the basketball rolls down;

3) the heights of the rear cross arm support and the upper fixing support are determined according to the height of a basketball shooter, and the principle is that the shooting mesh supported by the front end upper fixing support and the rear cross arm support forms a 40-degree included angle with the horizontal plane, the basketball shooter jumps up to shoot at a hand-out angle of 50 degrees, a shot basketball vertically penetrates through a shooting hole of the shooting mesh, the height of the rear end upper fixing support is consistent with that of the front end upper fixing support, and the hand-out angle is an included angle between the flight direction of the basketball flying away from a hand and the horizontal plane when the basketball is shot;

4) the height of the vertical support bracket is ensured to meet the height requirement of the upper fixing bracket, and the vertical support bracket can be close to the top of a narrow indoor space and does not need to be higher than the highest point of a standard shooting action flight track;

5) the distance between the front end vertical support bracket and the rear end vertical support bracket ensures that a shot basketball vertically penetrates through a shooting hole of shooting net cloth, touches a blocking net cloth, then penetrates through a ball leaking hole of the shooting net cloth, and finally freely rolls into a receiving net cloth;

6) the middle part of the front end upper fixing bracket can be tied with an upper line selectively, the soft small ball XQ is hung down, and the soft small ball XQ is swung manually so as to practice shooting in an interference state;

7) the side inclined support is used for fixedly supporting the containing screen cloth in a winding mode through a wire, so that a basketball rolled down along the containing screen cloth is either stopped at the bottom of the containing screen cloth and is convenient for a basketball shooter to pick up, or flies up to the basketball shooter along the containing screen cloth and is convenient for the basketball shooter to receive, and the side inclined support is also used for fixing the four vertical supporting supports;

a design drawing of the basketball shooting machine is suitable for the basketball shooting machine with the height of 1.7 meters and the indoor clear height of 2.61 meters, and is shown in figures 3 to 5, wherein figure 3 is a side view of the basketball shooting machine, figure 4 is a front view of the basketball shooting machine, and figure 5 is a top view of the basketball shooting machine. Fig. 6 is a side view of a real basketball court standard action basketball shooting machine. The sizes are marked in detail, the description refers to the description of the attached drawings, and the length of the support can be adjusted when the height is not 1.7 meters.

Advantageous effects
