Three-point ball training rod

Abstract

A trisection training rod is an auxiliary training instrument for trisection shooting, is a training instrument researched and developed according to the necessary conditions of accurate trisection shooting, can help an athlete to improve the sensing ability and the control ability of fingers and wrists on the gravity center of an object moving on the hands, and meanwhile increases the strength of the fingers, the wrists and the arms. Through the training of the three-point ball training rod, the hit rate of the three-point ball can be greatly improved. The whole body is in a short and thick rod shape, and the whole surface is made of damping materials. The device is characterized by being adjustable in weight, adjustable in length and adjustable in diameter of a middle hand grabbing part.

Description

Technical Field

[0001] The invention discloses a three-point shooting training stick (hereinafter referred to as the training stick) which relates to the three-point shooting project in the field of basketball, and is specifically an auxiliary training device for three-point shooting. Background Art

[0002] Many basketball enthusiasts or basketball players have a low three-point shooting rate because the force exerted by the fingers on the basketball deviates from the center of gravity of the basketball at the moment when the fingers leave the surface of the basketball. Three-point shooting is a long-distance shooting, and its accuracy requirements are extremely strict, which requires the five fingers to accurately locate the center of gravity of the moving basketball and make the force exerted by the five fingers continuously act on the center of gravity of the basketball. During the training process, the center of gravity of the existing training equipment is stationary relative to the hand, and the trained force lacks directionality, which is far from meeting the needs of three-point shooting. Summary of the invention

[0003] The three-point training stick is a training device developed based on the necessary conditions for accurate three-point shooting. It can help athletes improve their finger and wrist perception and control of the center of gravity of objects moving in their hands, while increasing the strength of their fingers, wrists and arms. It is characterized by adjustable weight, adjustable length, and adjustable diameter of the middle grip. The three-point training stick is low-cost and easy to promote.

[0004] The three-point training stick is short and thick. To protect the ground, its surface is designed with shock-absorbing materials. To reduce enterprise costs, it can be divided into large, medium and small models. The overall weight is 2~4.5 kg, the overall length is 310~560 mm, and the overall diameter is 70~120 mm. The overall diameter of the training stick can be exactly the same, or the diameter of the middle hand grip is slightly larger than the two ends, with a diameter difference of 2~10 mm.

[0005] Components, specifications, and materials of the training stick: The training stick consists of a large rubber nut ❶ (with an embedded nut in the center), an embedded nut, a grip ❹, a thickened outer jacket at the grip ❻, a weight plate ❷, a position filling cake ❸, and a center shaft ❺. Among them, the large rubber nut is made of shock-absorbing materials such as rubber; the embedded nut is made of steel, plastic, etc.; the outer part of the grip is made of elastic and soft materials such as latex and knitwear (the feel is similar to the surface of a basketball), and the inner part is made of light materials such as foam and plastic; the thickened outer jacket at the grip is made of elastic and soft materials such as latex and knitwear; the weight plate is made of iron, rubber, etc.; the position filling cake is made of elastic and light materials such as sponge and pearl cotton foam; the center shaft is made of steel, plastic, etc. The length of the large rubber nut is 40~80 mm, the length of the center shaft is 310~480 mm, the length of the grip is 140~220 mm, the length and diameter of the thickened outer jacket at the grip are the same as the grip, and the thickness is 2~5 mm.

[0006] Adjustable method: weight adjustment: by replacing or increasing or decreasing the weight plate and the position filling cake, the weight can be adjusted by 1~2.5 kg; length adjustment: based on the characteristic of the large rubber nut itself being longer, the length can be adjusted by screwing in or out the thread and increasing or decreasing the position filling cake; the diameter adjustment at the grip: by increasing or decreasing the thickened jacket at the grip, the diameter can be adjusted according to the size of the individual's hand, so that the hand feels swollen when gripping the grip.

[0007] Description of the drawings: Figure 1 This is the overall appearance picture; Figure 2 It is the structural breakdown and accessories diagram; Figure 3 For training graph.

[0008] The training method is to imitate the shooting action, hold the training stick with one hand and raise it over the shoulder, and make the training stick rotate in the hand under the control of five fingers. After a period of training with the training stick, the three-point shooting rate can be greatly improved.

Claims

1. The structure of the three-point shooting training stick (hereinafter referred to as the training stick) is composed of a hand grip ❹ in the middle, large rubber nuts ❶ at both ends (the center is an embedded nut), a weight plate ❷, and a position filling cake ❸, which are combined together through a central axis ❺. The whole is in the shape of a short and thick stick, and the entire surface is designed with shock-absorbing materials.

2. The overall diameter of the training stick is 70~120 mm, the overall length is 310~560 mm, and the overall weight is 2~4.5 kg.

3. The overall diameter of the training stick can be exactly the same, or the diameter of the middle grip can be slightly larger than the two ends, with a diameter difference of 2 to 10 mm.

4. The length of the large rubber nut is 40~80 mm, and it is made of shock-absorbing materials such as rubber; the length of the hand grip is 160~220 mm, and the outer material is elastic and soft materials such as latex and knitwear, and the inner material is light materials such as foam and plastic; the length and diameter of the thickened jacket ❻ at the hand grip are the same as the hand grip, with a thickness of 2~5 mm, and it is made of elastic and soft materials such as latex and knitwear; the filling cake at the position is made of elastic and light materials such as sponge and pearl cotton.

5. The training stick features adjustable weight, adjustable length, and adjustable diameter at the middle grip. The adjustable methods are as follows: weight adjustment is achieved by replacing or increasing or decreasing the weight plate and the position filling cake; length adjustment is based on the long nature of the large rubber nut, by screwing in or out more or less threads and increasing or decreasing the position filling cake at the same time; the grip diameter is adjusted by increasing or decreasing the thickened outer jacket at the grip.
