Description

Technical Field

[0001] The invention belongs to the technical field of sports training, and in particular relates to a striking stick for sports training and a training method. Background Art

[0002] In the existing sports training methods, race walking and rope skipping are reciprocating movements. The coordination of hands and feet in double rope skipping is equally important, but when the rope skipping partners complete the exercise with the same action, they achieve the same frequency of the action according to the agreed rhythm, and the completion of different action choreography training methods is first based on the basic sports quality of the body.

[0003] In view of the above situation, a double stick exercise is designed with the reciprocating movement of the upper limbs as the main aspect of the exercise. The length and difficulty of the body's movement position memory are used to distinguish the different levels of the exercise. It aims to test and adjust the general activity ability of the upper limbs and arms, as well as the ability of the partners to cooperate in the sports environment in which the object of externalized movement memory (referring to the partner of the stick) participates in prompting and restricting the movement process.

[0004] The existing fighting sticks are wooden ash rods, rattan sticks, and artificial sticks, which have certain use value in fighting and striking each other. However, based on the characteristics of this sport, these previous equipments have shortcomings when used as the fighting sticks of this design. This is because, firstly, the movement mode of this fighting stick has been set to hold the stick with both hands, and use the two ends of the stick to strike quickly and cyclically for a certain period of time. The two hands will form torque on the stick body, causing the stick body to rotate. This tendency of the stick body rotation will cause continuous friction to the palm, especially the tiger's mouth, and damage the skin; secondly, the movement mode of this fighting stick is to draw on the idea of ​​the "strike" game of the previous "stick" action, select a process in which the offensive and defensive sides are in a balanced state, and both sides use the same offensive and defensive actions at the striking point, and avoid the direction of the force parallel to the straight section of the other side's stick body at the moment of striking. This "force transformation" method is presented in the form of "strike" that pursues speed, rather than the purpose of the power confrontation between the two sides. It aims to enable both sides to complete more strikes within a certain period of time. However, this "force transformation" method is very subtle. If it is not done well, it may damage the equipment, which is a safety hazard. Third, the sound of the strike is very rhythmic, but it is generally difficult to distinguish the different frequencies from the impact of the sticks. It is impossible to describe the striking position of the two people's equipment during the strike, and it is also impossible to describe the posture of the arm movement. Summary of the invention

[0005] The purpose of the present invention is to provide a striking stick for sports training and a training method. When the striking stick is used for rapid striking, the base of the hand of the trainee can receive a certain buffering force, thereby reducing the friction at the base of the hand of the trainee and avoiding damage to the skin of the hand. Using this striking stick training method, the striking method can be determined according to the different purposes of practice, competition, or testing, so as to train the ability of coordinated movement between companions.

[0034] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0035] Example 1

[0036] This embodiment provides a Figure 1 and Figure 2 The striking stick for sports training shown in the figure comprises a first column core 1, a second column core 2 is connected to the left end of the first column core 1, and a third column core 3 is connected to the right end of the first column core 1. Specifically, the first column core 1, the second column core 2 and the third column core 3 can be integrally formed, or can be connected by interference fit, thread, welding and the like. Specifically, in the present embodiment, the first column core 1, the second column core 2 and the third column core 3 are interference connections, and this connection method can avoid scratches on the user's hands at the connection; the first column core 1 of the striking stick is a hand grip area, the second column core 2 is a first striking area, and the third column core 3 is a second striking area.

[0037] An elastic airbag 4 is sleeved on the outside of the first column core 1. Specifically, the elastic airbag 4 is fixed on the side wall of the first column core 1. A support frame 5 for supporting the elastic airbag 4 is provided inside the elastic airbag 4. Specifically, the support frame 5 is located at the center of the elastic airbag 4, so that there is a gap between the left and right sides of the support frame 5 and the inner wall of the elastic airbag 4. The support frame 5 includes a plurality of semi-ring frames 501 distributed around the circumference of the first column core 1. Both ends of the semi-ring frames 501 are connected to the first column core 1, and the middle part of the semi-ring frames 501 is connected to the elastic airbag 4, preferably a fixed connection.

[0038] Further, such as Figure 2As shown, the left end of the second column core 2 is sleeved with a drum head 6, and a plurality of brackets 7 for supporting the drum head 6 are arranged inside the drum head 6. The plurality of brackets 7 are sleeved on the second column core 2. Specifically, the number of brackets 7 in the drum head 6 is not less than three, and the brackets 7 are fixedly connected to the drum head 6. The plurality of brackets 7 divide the drum head 6 into a plurality of striking areas, and each striking area is distinguished by a different color. The set drum heads 6 can make sounds when they strike each other, which is convenient for controlling the rhythm by following the sounds during training, and can improve the training efficiency.

[0039] Further, such as Figure 2 and Figure 3 As shown, the bracket 7 includes a first bearing 701 and a support ring 702. The first bearing 701 is sleeved on the second column core 2. Specifically, the first bearing 701 is connected to the second column core 2 by interference fit. The support ring 702 is located outside the first bearing 701. The support ring 702 and the first bearing 701 are coaxially arranged. A plurality of spokes 703 are connected between the inner side of the support ring 702 and the first bearing 701. The outer side of the support ring 702 is fixedly connected to the drum head 6. The right open end of the drum head 6 is fixedly connected to the second bearing 8. The second bearing 8 is sleeved on the second column core 2. Specifically, the second bearing 8 is connected to the second column core 2 by interference fit. The drum head 6 can be rotated around the second column core 2 to avoid the strong impact of the strike, which helps to experience the method of "transforming force" so that both parties can complete more strikes in a certain period of time, and is conducive to extending the service life of the striking stick.

[0040] Further, such as Figure 2 As shown, the lengths of the striking areas are different, and the tightness of the drumhead 6 in the striking areas is different, so that different frequencies and pitches can be emitted when striking each other. When striking each other, each predetermined striking method arrangement can strike different melodies, and the striking position of the third column core 3 can be determined by the sound, so that the trainee's arm movements can be judged by the sound.

[0041] Further, such as Figure 2 As shown, the pair of batons also includes three partitions 9 distributed in a circular array, the first column core 1, the second column core 2 and the third column core 3 are all hollow structures, and the three are internally connected, the left end of the second column core 2 and the right end of the third column core 3 are both closed ends, and the three partitions 9 separate the first column core 1, the second column core 2 and the third column core 3 into three independent cavities. The partitions 9 can improve the bearing strength of the pair of batons, and can effectively prevent the pair of batons from breaking when in use.

[0042] Further, such as Figure 2 and Figure 4 As shown, in order to improve the smoothness of the upper inner cavity, the lower inner cavity and the cavity in the elastic airbag 4, a connecting hole 14 is opened on the upper side of the upper inner cavity and the lower side of the lower inner cavity.

[0043] Further, such as Figure 2 and Figure 4 As shown, the number of the semi-ring frames 501 is three, and three circumferentially distributed diaphragms 401 are provided in the elastic airbag, and the diaphragms 401 are fixedly connected to the first core column 1. The three diaphragms 401 divide the interior of the elastic airbag 4 into three cavities, and the three cavities are not connected. The three semi-ring frames 501 are respectively located in the three cavities, and the side wall of the first column core 1 is provided with three mounting holes 502 for the open ends of the semi-ring frames 501 to pass through. The open ends of the three semi-ring frames 501 pass through the corresponding mounting holes 502 and are located inside the independent cavities. Specifically, there is always a gap between the mounting holes 502 and the semi-ring frames 501, so that the semi-ring frames 501 have an upward and downward range of movement in the mounting holes 502, so that when the elastic airbag 4 is contracted by force, the semi-ring frames 501 can contract into the independent cavity, and at the same time, the mounting holes 502 connect the corresponding independent cavity with the cavity.

[0044] Further, such as Figure 4 As shown, the end of the semi-ring frame 501 located inside the first column core 1 is provided with anti-skid and wear-resistant materials such as rubber, cotton yarn or anti-skid fiber, so that the end is larger than the diameter of the mounting hole 502, thereby preventing the semi-ring frame 501 from falling off the first column core 1, and the middle of the three semi-ring frames 501 are provided with air outlets 503, which are through holes, and there are sounding elements 504 in the air outlets 503, and the sounding elements 504 are used to make sounds when air flows through the air outlets 503. Specifically, the sounding elements 504 are whistles, and the elastic airbag 4 is also provided with a sounding hole 10 connected to the air outlet 503. With the above structure, when the elastic airbag 4 is deformed by the hand force during use, it can be ensured that at least one of the three sounding elements 504 can make sounds. Further, the inner side of the elastic airbag 4 is provided with anti-skid and wear-resistant materials such as rubber, cotton yarn or anti-skid fiber around the two sounding holes 10. When in use, two hands are used to twist and press the elastic airbag 4 to make the two sounding elements 504 emit sounds, and the consistency of the movements of the two hands can be judged based on the consistency of the sounds.

[0045] like Figure 5 As shown, the number of the semi-ring frames 501 is two. When there are two semi-ring frames 501, the number of the partition plate 9 is one. One partition plate 9 divides the interior of the first column core 1 into two independent cavities. If there are two diaphragms in the elastic airbag 4, the two diaphragms divide the elastic airbag 4 into two upper and lower cavities, and the two semi-ring frames 501 are respectively located in the two cavities. The number of the semi-ring frames 501 can also be 4, 5, 6..., the cavity inside the elastic airbag 4 and the independent cavity in the first core column 1 are always the same as the number of the semi-ring frames 501, and can be customized according to actual needs.

[0046] Further, such as Figure 4As shown, a plug 11 is inserted into the upper end of the air outlet 503, and the plug 11 can block the gas flowing out of the air outlet 503. When the air outlet 503 needs to make a sound, the plug 11 can be pulled out.

[0047] Further, such as Figure 4 As shown, the upper end of the plug 11 is fixedly connected with a buckle cover 12, and one side of the buckle cover 12 is hinged to the upper end of the air outlet 503, thereby effectively preventing the plug 11 from being lost.

[0048] When in use, the trainee holds the elastic airbag 4, and the elastic airbag 4 provides elastic support for the trainee's hand. When using the pair of hitting sticks to hit quickly, the trainee's hand base can receive a certain buffer force, reducing the friction of the trainee's hand base and avoiding damage to the hand skin; and when using the pair of hitting sticks to hit quickly, it can avoid the strong impact of hitting, which helps to experience the method of "transforming force" and enables both parties to complete more hitting times within a certain period of time. When two trainees use the hitting sticks to hit each other, they hold the hitting sticks in the same direction, and use the third column core 3 as a drumstick to hit the drum surface 6.

[0049] Example 2

[0050] This embodiment provides a Figure 6 The striking stick for sports training shown in the figure comprises a first column core 1, a second column core 2 and a third column core 3. The difference between this embodiment and the embodiment 1 is that the component connected to the second column core 2 is different. Specifically, a tuning fork 13 is provided at the left end of the second column core 2. In this embodiment, the second column core 2 and the tuning fork 13 are connected in a detachable manner. Specifically, the connection between the two is a threaded connection, so that the tuning fork 13 can be easily disassembled. When striking each other, the third column core 3 can make a sound when hitting the tuning fork 13.

[0051] Example 3

[0052] The present embodiment provides a training method using the above-mentioned striking sticks. First, the standing positions of two persons are determined. Then, each of the two persons holds a striking stick and an elastic air bag 4. The two persons twist and press the elastic air bag 4 with both hands to make the two sound producing elements 504 emit sounds. The symmetry of the movements of both hands is judged according to the consistency of the sounds emitted. Finally, a striking method is selected according to the training needs for mutual striking. When striking each other, one person holds the third column core 3 of the striking stick and strikes the drum head 6 of the striking stick held by another person. The drum head 6 emits sounds when striking, and the trainer counts by the sounds emitted by the drum head 6.

[0053] When the goal is striking speed, the number of times the sound is emitted through the drumhead is counted and scored; when the goal is music, the accuracy of the striking rhythm is scored, and those who strike the rhythm perfectly can get the highest score.

[0054] During training, you can also set a promotion mode based on the scores, and train multiple groups of trainees using a competition scoring method.

[0055] The four types of mutual striking mentioned in the above training methods are: upper left strike, upper right strike, lower left strike, and lower right strike. That is, when striking each other, there are four directions: upper left, upper right, lower left, and lower right, and the strikes collide between the two bodies.

[0056] The striking methods are also divided into:

[0057] ① Straight strike: the shoulder joint rotates internally, and the elbow joint moves outward to strike each other;

[0058] ② Counterattack: external rotation of the shoulder joint and inward movement of the elbow joint to strike each other;

[0059] The strokes are arranged as follows:

[0060] (1) The unit attack method is: upper left attack, upper right attack, lower left attack, lower right attack. The cycle time is set to T, and the cycle period is one attack.

[0061] ① Left upper click: left upper click;

[0062] ②Right click: right click;

[0063] ③ Left lower attack: left lower attack;

[0064] ④Right click: right click;

[0065] ⑤There are 1+1+1+1=4 arrangements in total, i.e., there are 4 ways of playing with a cycle as one attack.

[0066] (2) The unit attack method is: upper left attack, upper right attack, lower left attack, lower right attack. The cycle time is set to T, and the cycle period is two attacks.

[0067] ① Starting from the left upper click, there are: left upper click-right upper click, left upper click-left lower click, left upper click-right lower click;

[0068] ② Right-up click starts with: right-up click-left-up click, right-up click-left-down click, right-up click-right-down click;

[0069] ③ Starting from the lower left click, there are: lower left click-upper left click, lower left click-upper right click, lower left click-lower right click;

[0070] ④ Right click starts with: right click-upper left click, right click-upper right click, right click-lower left click;

[0071] ⑤ There are 3+3+3+3=12 ways of arrangement, that is, there are 12 ways of playing with two hits in a cycle;

[0072] (3) The unit attack method is: upper left attack, upper right attack, lower left attack, lower right attack. The cycle time is set to T, and the cycle period is three attacks.

[0073] ① Starting from the left upper hit, there are: left upper hit-right upper hit (-left upper hit, -right upper hit, -left lower hit, -right lower hit), left upper hit-left lower hit (-left upper hit, -right upper hit, -left lower hit, -right lower hit), left upper hit-right lower hit (-left upper hit, -right upper hit, -left lower hit, -right lower hit);

[0074] ② Right-up hit starts with: right-up hit-left-up hit (-left-up hit, -right-up hit, -left-down hit, -right-down hit), right-up hit-left-down hit (-left-up hit, -right-up hit, -left-down hit, -right-down hit), right-up hit-right-down hit (-left-up hit, -right-up hit, -left-down hit, -right-down hit);

[0075] ③ Starting from the left lower stroke, there are: left lower stroke-left upper stroke (-left upper stroke, -right upper stroke, -left lower stroke, -right lower stroke), left lower stroke-right upper stroke (-left upper stroke, -right upper stroke, -left lower stroke, -right lower stroke), left lower stroke-right lower stroke (-left upper stroke, -right upper stroke, -left lower stroke, -right lower stroke);

[0076] ④ Starting from right-down click: right-down click-upper-left click (-upper-left click,-upper-right click,-lower-left click,-lower-right click), right-down click-upper-right click (-upper-left click,-upper-right click,-lower-left click,-lower-right click), right-down click-lower-left click (-upper-left click,-upper-right click,-lower-left click,-lower-right click)

[0077] ⑤ There are 3×4+3×4+3×4+3×4=48 ways of arrangement, that is, there are 48 ways of playing with three hits in a cycle;

[0078] Infinite ways of playing: From the above, we can conclude that if there are n strokes per cycle, and if n>0 and increases infinitely, the function f(n) also increases infinitely, then it is said that when n→+∞, the function f(n)→+∞. Since the number of stroke arrangements is infinite, the number of comparable musical temperaments is also infinite.

[0079] The standing positions are as follows, and trainers can choose according to training needs.

[0080] ① Two people stand facing each other: one person's left shoulder to the other person's right shoulder, one person's right shoulder to the other person's left shoulder, with their chests facing each other;
