Description

Technology Field

[0001] The embodiments disclosed in this document relate to technology related to shooting training equipment in the field of basketball. Background Technology

[0002] Traditionally, the two-motion shooting method was primarily used, in which a player jumps high to avoid defensive blocking, pauses briefly at the peak of the air to secure height and aiming time, and then throws the ball. However, two-motion shooting is a shooting technique that relies excessively on the strength of the lower body and arms rather than full-body coordination, which can result in a loss of distance. Additionally, two-motion shooting has the disadvantage that defenders can easily catch up due to the delay that occurs when jumping after dribbling or changing direction, so it has limitations that make it advantageous only to shooters with excellent physical condition and athletic ability.

[0003] Accordingly, one-motion shooting is emerging as a key technique in modern basketball. One-motion shooting is a method of throwing the ball without delay following a dribble or a vigorous change of direction. To execute a one-motion shot, the shooter must complete their aim the moment they catch the ball and immediately shoot by rapidly lifting the ball from near the pelvis above their head. Since there is no delay from the shooter's ball-catching motion to the shooting motion, the shot is completed before the defender can react. The problem to be solved

[0004] One-motion shooting is a method in which the shooter stands near the pelvis, dips the ball, and then releases it by extending the entire body in one motion—in the order of the balls of the feet, ankles, knees, hips, shoulders, elbows, wrists, and fingertips—so the ball travels much farther than in two-motion shooting. Since shooting in one-motion shooting relies on such rapid full-body coordination, accurate aiming for the shot must be achieved from the very beginning of the preparation stance when dipping the ball.

[0005] Meanwhile, the shooter relies on their dominant eye to aim for the shot. The dominant eye refers to the eye that focuses among a person's two eyes, and the shooter obtains the depth perception necessary for shooting through the dominant eye and the other eye that serves as a backup. Additionally, the dominant hand refers to the hand primarily used when handling the ball.

[0006] In the case of a shooter whose dominant eye and dominant hand are aligned (hereinafter referred to as an Ipsilateral Dominant Shooter), if a follow-through is performed using the dominant hand near the dominant eye to throw the ball, the ball will fly along the path aimed through the dominant eye, and the success rate of the shot will increase. The shooter trains to extend the joints of the entire body in the direction aimed through the dominant eye, and by honing the optimal extension of the entire body, the shooter performs one-motion shooting training.

[0007] However, the above training method is difficult to apply to shooters whose hand dominance and eye dominance are opposite (hereinafter referred to as "cross-dominant shooters"). A cross-dominant shooter refers to a right-handed shooter whose left eye is dominant, or a left-handed shooter whose right eye is dominant. This is because the direction of the dominant eye and the dominant hand do not align in cross-dominant shooters; consequently, when shooting using the dominant hand along the path aimed through the dominant eye, it is difficult for them to perform the same full-body expansion as an ipsilateral dominant shooter. Consequently, cross-dominant shooters are often unable to execute one-motion shooting and frequently rely solely on a two-motion shooting method that overly depends on the strength of the wrists and lower body. Furthermore, many end their careers early due to issues with shooting accuracy.

[0008] According to one embodiment of the present invention, a shooting training device for cross-proactive shooters is provided that can hone a natural full-body spread, such as when a one-motion shooter performs a one-motion shoot. means of solving the problem

[0009] A shooting training device according to one embodiment disclosed in this document comprises a ball having a hole penetrating both ends, a guide rod disposed inside the penetrating hole and functioning as a rotation axis of the ball, a base platform including a first line of sight alignment point for guiding the dominant eye, a first string connected to one end of the guide rod and a first fixed point of the base platform, and a second string connected to the other end of the guide rod and a second fixed point of the base platform, wherein at least a portion of the first string and at least a portion of the second string can be aligned substantially parallel to a virtual line connecting the user's dominant eye and the line of sight alignment point during a shooting motion of the user. Effects of the invention

[0010] Through a shooting training device according to one embodiment disclosed in this document, a cross-dominant shooter can be trained to perform full-body coordination from a ready position to a shooting position similar to that of an ipsilateral dominant shooter. Additionally, through the shooting training device, the cross-dominant shooter can train a diagonal delivery that can have substantially the same shooting accuracy as the vertical delivery of an ipsilateral dominant shooter, as a ball path naturally formed from a ready position to a follow-through position.

[0011] In addition, various effects that can be identified directly or indirectly through this document may be provided. Brief explanation of the drawing

[0013] Hereinafter, various embodiments of the present invention are described with reference to the accompanying drawings. However, this is not intended to limit the present invention to specific embodiments and should be understood to include various modifications, equivalents, and / or alternatives of the embodiments of the present invention.

[0014] FIG. 1 is a structural diagram of a shooting training device (100) according to one embodiment. FIG. 2 is a cross-sectional view of a ball (10) included in the shooting training device (100) according to one embodiment and a plan view of a base platform (50). FIG. 3 is a diagram for explaining the operation method of the shooting training device (100) according to the progress of a user's shooting motion according to one embodiment. The structure and operation method of the shooting training device (100) will be explained below with reference to FIG. 1 to FIG. 3. The user in FIG. 1 and FIG. 3 below is an example of a right-handed cross-dominant shooter with a dominant left eye. However, not only cross-dominant shooters but also users who are homodominant shooters can perform shooting training through the shooting training device (100).

[0015] A shooting training device (100) according to one embodiment may include a ball (10), a guide rod (20), a first string (30), a second string (40), and a base platform (50).

[0016] A ball (10) according to one embodiment can be understood as a ball having substantially the same size as a basketball made for shooting training. The ball (10) may have holes (12) that penetrate through both ends.

[0017] A guide rod (20) according to one embodiment may be placed inside a hole (12) of a ball (10) and may function as a rotation axis of the ball (10). The ball (10) rotates around the guide rod (20) as an axis according to the user's shooting motion.

[0018] A base platform (50) according to one embodiment may include a first fixed point (52) for a first string (30), a second fixed point (54) for a second string (40), and a visual alignment point (56) for a dominant eye guide. An example of the base platform (50) in FIG. 1 is shown installed on a floor surface where the user's foot is positioned. The shape of the base platform (50) is not limited to the example in FIG. 1 and may be implemented in various forms including the first fixed point (52), the second fixed point (54), and the visual alignment point (56).

[0019] According to one embodiment, one end of the first string (30) may be connected to one end (22) of the guide rod (20), and the other end of the first string (30) may be connected to a first fixed point (52) of the base platform (50). One end of the second string (40) may be connected to the other end (24) of the guide rod (20), and the other end of the second string (40) may be connected to a second fixed point (54) of the base platform (50). The first string (30) and the second string (40) may be bent or stretched according to the movement of the ball (10). In various embodiments, the first string (30) and the second string (40) may be formed of an elastic material.

[0020] The user can assume a set position such that the user's dominant eye is positioned vertically parallel to the eye alignment point (56) of the base platform (50). Through the eye alignment point (56), unnecessary compensatory movements can be prevented, particularly when the user is a cross-dominant shooter, when preparing to shoot with the ball (10) placed near the pelvis. For example, a user who is left-dominant and right-handed is likely to perform compensatory movements that put unnecessary force on the shoulder, such as excessively narrowing the right shoulder to the left (toward the dominant eye) or pulling it toward the chest to throw the ball in front of the left eye. Because these compensatory movements put force on the user's shoulder, it becomes difficult for the user to perform effective full-body coordination. The shooting training device (100) allows the user to take a set position aligned with the dominant eye through the eye alignment point (56), thereby eliminating unnecessary compensatory movements that may occur during the set position. The shooting training device (100) can induce the user to comfortably hold the ball (10) and assume a ready position similar to that of an east-side dominant shooter.

[0021] Referring to FIG. 3, the one-motion shooting motion may include the actions of a ready position (310), a shooting pocket (320), and a follow-through (330). The user performs shooting training by repeating the ready position (310), the shooting pocket (320), and the follow-through (330). The ready position (310) can be understood as a posture in which the knees are bent and the ball (10) is placed near the pelvis. Aiming for the shot must be completed starting from the ready position (310). The shooting pocket (320) can be understood as a shooting ready position in which the ball (10) is raised to the front of the face (usually near the eyes or forehead) and held stably with both hands. The follow-through (330) can be understood as a finishing motion in which the wrists are gently bent toward the rim and the shooting trajectory is stable. FIG. 1 is an example illustrating a shooting training device (100) in the shooting pocket motion.

[0022] In one embodiment, at least a portion of the first string (30) and at least a portion of the second string (40) may be aligned substantially parallel to a virtual line (60) connecting the user's dominant eye and the gaze alignment point (56) as the user's shooting motion progresses. Additionally, the virtual line (60) may be aligned substantially parallel to the central axis (14) of the ball (10). Accordingly, the direction of the dominant eye of the cross-dominant shooter and the central axis (14) of the ball (10) become parallel, so that the follow-through in front of the dominant eye can be formed along a natural path similar to passing the ball toward the goal. Referring to FIGS. 1 and 3, a virtual line (60) extending from the user's dominant eye, the left eye, to the gaze alignment point (56) is illustrated.

[0023] In the case of a cross-dominant shooter, the ball moves along a diagonal delivery line extending from the shooter's dominant hand to the dominant eye according to the shooter's shooting motion. Accordingly, the delivery of the ball is carried out along the diagonal delivery line. Diagonal delivery is a concept corresponding to the vertical delivery extending from the dominant hand to the dominant eye of an east-dominant shooter, and cross-dominant shooters can repeatedly train the diagonal delivery of the ball for one-motion shooting through a shooting training device (100). This diagonal delivery line of the ball enables the shooter to continuously apply throwing force from the ready position (310) to the follow-through position (330), thereby making it possible to perform one-motion shooting with strong power, which was difficult for a cross-dominant shooter to perform. Unlike two-motion shooting, where there is a delay in the shooting pocket (320) position, the transmission of power through this diagonal delivery line allows the shooter to reduce wrist strain and use the lower body power condensed from the ready position (310) for shooting. Accordingly, cross-dominant shooters learn body coordination through diagonal delivery corresponding to body coordination through vertical delivery of east-side dominant shooters, and are able to perform one-motion shooting with increased accuracy and power.

[0024] Referring to FIG. 3, at least a portion of the first string (30) and at least a portion of the second string (40) may change from a bent state to a taut state depending on the movement of the ball caused by the user's shooting motion. Depending on the user's shooting motion, the ball (10) is lifted into the air while rotating with the through hole (12) as the axis of rotation, and at least a portion of the first string (30) and at least a portion of the second string (40) may change from a bent state to a taut state. The portions of the first string (30) and the second string (40) in the taut state may be aligned vertically with respect to the ground where the user is standing (see shooting pocket (320), follow-through (330)). For example, in the shooting pocket (320) and follow-through (330), the entire portion of the first string (30) and the second string (40) is shown in an extended state, but this is an example, and depending on the length of the first string (30) and the second string (40) and / or the user's height, a portion of the first string (30) and the second string (40) may be in an extended state and the remainder in a bent state. As the user's shooting motion is performed, at least a portion of the first string (30) and at least a portion of the second string (40) (the portion of the first string (30) and the second string (40) that is in an extended state) may be aligned substantially parallel to the imaginary line (60) connecting the user's dominant eye and the line of sight alignment point (56) and the central axis (14) of the ball (10). In particular, when the first string (30) and the second string (40) are in an extended state aligned vertically with the ground during the follow-through (330), it can be confirmed that the diagonal delivery through the shooting training device (100) has been trained.

[0025] Since the ball (10) is rotated with the guide rod (20) as the axis of rotation, the first string (30) and the second string (40) are not twisted according to the rotation of the ball (10). In various embodiments, the guide rod (20) may be formed of a material having flexural rigidity that can maintain a predetermined shape when the ball (10) rotates.

[0026] Referring to FIG. 2, the first distance (a) between the first fixed point (52) of the base platform (50) and the line of sight alignment point (56), and the second distance (b) between the second fixed point (54) and the line of sight alignment point (56) can be formed substantially identically. Here, substantially identical distance means identical distances ignoring error distances that may occur during the manufacturing process. Since the first fixed point (52) and the second fixed point (54) are connected to both ends of the ball (10) through the guide rod (20), the line of sight alignment point (56) is located on a line parallel to the central axis (14) of the ball (10). Accordingly, cross-dominant shooters can also position the central axis (14) of the ball (10) in front of their dominant eye through the shooting training device (100), thereby allowing them to train high-accuracy one-motion shooting through full-body coordination similar to the shooting motion of east-dominant shooters.

[0027] In various embodiments, the lengths of the first string (30) and the second string (40) may be configured to be adjustable. For example, the first string (30) and the second string (40) may be configured to be adjustable from 250 cm to 280 cm depending on the user's height.

[0028] In various embodiments, the auxiliary hand, rather than the user's main hand, may be aligned parallel to the first string (30) or the second string (40) located in the direction of the auxiliary hand. For example, referring to the follow-through (330) of FIG. 3, the user's auxiliary hand (3) is positioned parallel to the second string (40) in the direction of the auxiliary hand (30). In the one-motion shooting motion, training by extending the auxiliary hand (3) toward the goal can further enhance the training effect of the shooting training device (100). Similarly, training by extending the index finger of the main hand (2) toward the goal in parallel with the first string (30) in the direction of the main hand (2) can further enhance the training effect of the shooting training device (100).

[0029] In various embodiments, even if the user is a homocentric shooter, training can be performed by using the shooting training device (100) in the same way as a cross-centric shooter trains. A user who is a homocentric shooter can train by aligning their dominant eye through the gaze alignment point (56) of the shooting training device (100), assuming a ready position (310), and then performing shooting pocket (320) and follow-through (330) movements. As with the case of a cross-centric shooter, as the user's shooting movement progresses, at least a portion of the first string (30) and at least a portion of the second string (40) can be aligned substantially parallel to a virtual line (60) connecting the user's dominant eye and the gaze alignment point (56). As the first string (30) and the second string (40) change from a bent state to an extended state, and at least a portion of the first string (30) and at least a portion of the second string (40) become perpendicular to the ground where the user is located, a vertical delivery of the ball (10) from the dominant hand to the dominant eye is achieved. Through this process, the dominant shooter can also train one-motion shooting through the shooting training device (100).

[0030] FIG. 4 is a drawing for illustrating an auxiliary device (70) and auxiliary glasses (80) according to one embodiment. Referring to FIG. 4, the shooting training device (100) may further include an auxiliary device (70) positioned at a location spaced apart from the base platform (50). The auxiliary device (70) may include a panel (72) with a second line of sight alignment point (76) for guiding the dominant eye and a support (74). The support (74) may be configured to be height-adjustable. The height of the panel (72) may be adjusted so that the second line of sight alignment point (76) is located between 45 and 50 degrees from the user's dominant eye in the user's shooting pocket position. The second line of sight alignment point (76) of the panel (72) may form an elevation angle of 45 to 50 degrees from the ground when the user gazes at the second line of sight alignment point (72) in the shooting pocket position.

[0031] In various embodiments, the shooting training device (100) may further include auxiliary glasses (80). The auxiliary glasses (80) may assist in the alignment of the user's dominant eye with the eye alignment point (56) of the base platform (50). The auxiliary glasses (80) may include a laser module (80). The auxiliary glasses (80) may include a dominant eye corresponding portion formed at a position corresponding to the user's dominant eye. The laser module (80) may be installed in the dominant eye corresponding portion. The laser module (80) may assist in the alignment of the user's eyes by irradiating a laser toward the eye alignment point (56) of the base platform (50). By irradiating a laser, a laser line (84) connecting the user's dominant eye and the eye alignment point (56) may be formed. The laser line (84) may be parallel to the virtual line (60) of FIGS. 1 and FIGS. 3.

[0032] FIG. 5 is an example of a shooting training device (200) in a modified form according to various embodiments. Referring to FIG. 5, the belt (90) can be understood as a modified form of the base platform (50) of FIG. 1. The belt (90) may include a first fixed point (52) for a first string (30), a second fixed point (54) for a second string (40), and a gaze alignment point (56) for a gaze guide. The belt (90) may be positioned around the user's waist. The user wears the belt (90) around their waist and can perform one-motion shooting training using the training method described above through FIG. 1 to FIG. 3 in a standing position or a sitting position (not shown) as in FIG. 1 and FIG. 3.
