Description

  The present invention relates to a pitching exercise tool that allows one person to practice the exercise of making the arm swing faster by increasing the follow-through while training the upper body and lower body of the wrist, elbow, arm, and shoulder.

  Conventionally, in pitching practice, there has been a shadow pitching method such as holding and shaking a towel by hand. In addition, a pitching training device that allows one person to practice pitching without a catching opponent has been considered (see, for example, Patent Document 1).

  JP 2006-218272 A

  In shadow pitching using towels, the arms were too light to swing out to follow-through because the towels were too light. Furthermore, with regard to catchers and fielders, it was impossible to practice throwing and throwing unless there was an opponent to catch. Further, according to Patent Document 1, the bending of the wrist can be adjusted so that the wrist does not return during the pitching. However, there were structural problems to increase the follow-through.

  An object of the present invention is to provide a pitching exercise tool that allows one person to practice swinging the arm faster by training the upper body and lower body of the wrist, elbow, arm, shoulder, etc. and increasing the follow-through. .

  In order to achieve the above object, in the pitching practice tool of the present invention, a spherical body, a mandrel fixed to a hole penetrating through the center of the spherical body and having a hole formed at an end thereof, and a string-shaped body, And a grip formed with a through hole in the inner longitudinal direction, the string-like body is movably attached to the through-hole inside the grip, and one end of the string-like body is formed at the end of the mandrel Forming a ring-shaped part to be anchored in the hole and fixing the wrist, grasping the spherical body and the grip with a finger in a state where the wrist is fixed to the ring-shaped part, performing a pitching operation, after throwing the spherical body, A pitching practice tool, wherein the grip is configured to be movable toward the wrist along the string-like body by gripping only the grip and swinging it to the end.

  One or a plurality of grooves or holes for inserting a finger are formed in the spherical body.

  Since the pitching practice tool of the present invention can perform pitching practice in a state where the ball is actually held, for example, the spherical body is supported by the first finger, the second finger, and the third finger, and the grip is held by the fourth finger and the fifth finger. By practicing pitching while holding the ball, it has a structure that allows the grip to be gripped and thrown out to the follow-through after throwing the spherical body. It is an excellent tool that can release the ball by the first action, hold the grip by the second action, and perform the action up to the follow-through. In the second operation, it is possible to take a large follow-through in order to grasp the grip and swing it out. By taking a large follow-through, a load is applied to the lower body, and the lower body is strengthened.

  The pitching practice tool of the present invention can be used not only for baseball but also for training for softball, handball, tennis, throwing, etc., because the weight and weight of the spherical body and mandrel can be determined by the material and shape. it can. When the spherical body is lightened, the material of the spherical body can be made of a resin such as plastic, and the mandrel can be made thin and short. Moreover, when making a spherical body heavy, it can form with raw materials, such as iron, for example, and a mandrel can be lengthened and lengthened. If you lighten it, you can swing out your arms quickly, and if you lighten it, you can stretch your wrists, elbows, shoulders, and strength training while swinging slowly. By adjusting the weight of the spherical body and the central part of the spherical body, it exhibits an excellent effect of being able to perform various exercises such as training to swing the arm quickly, stretching, warming up, and strengthening muscle strength.

  Since the pitching practice tool of the present invention can be fixed like a ring by protruding a string like a ring from the end side of the grip and passing through the wrist, the spherical body flies away from the body during pitching. This means that even if there is no catching partner, you can practice throwing and throwing by yourself. Also, by practicing pitching through the ring-shaped ring part up to the elbow, the elbow is raised and the lower body is used. It demonstrates the excellent effect of being able to throw with great ball power.

  By forming a hole or groove in the spherical body, the pitching practice tool of the present invention can grasp the spherical body lightly so that it can be supported by inserting a finger into the hole or groove instead of gripping it like a ball. By supporting the ball without gripping it, the upper body such as the shoulders and arms do not enter when throwing, and it is possible to throw using the lower half of the body that has been pulled from the upper body, delaying the release to the limit. Can do. In addition, when throwing the ball, it is possible to throw while assuming a higher ball, a lower ball, a changing ball, and the like, and an excellent effect of performing an image training of the pitch is exhibited.

  FIG. 1 is a perspective view of a pitching practice tool of the present invention. The pitching practice tool includes a spherical body 1 in which a mandrel 2 is fitted and fixed, rings 3, 3 'and one end side moored to the mandrel 2 via the rings 3, 3', and an arm is passed to the other end side. It is comprised from the string-like body 4 which has the ring-shaped part A fixed to a wrist, and the grip 5 which has the hole 5b which penetrated the string-like body 4 so that a movement was possible inside. A buffer material 6 is attached to the ring-shaped portion A of the string-like body 4. The spherical body 1 and the mandrel 2 can be formed of a hard material such as wood, iron, casting, stainless steel, rubber, etc. in order to maintain strength. It is also possible to reduce or increase the weight of the spherical body 1 by changing the thickness, length, and shape of the shaft of the mandrel 2 depending on the content of training.

  FIG. 2 is a front view of the pitching practice tool of the present invention. It consists of a spherical body 1 and a mandrel 2. In the front view, since the mandrel 2 is fixed to the hole penetrating through the center of the spherical body 1, the head portion of the mandrel 2 can be seen at the center of the surface of the spherical body. The head portion of the mandrel 2 may be a plug-like material or a paste so as to be covered.

  FIG. 3 is a rear view of the pitching practice tool of the present invention. It is composed of a spherical body 1, a string 4, a grip 5, and a buffer material 6. The role of the cushioning material 6 is to relieve the impact on the wrist, elbow, etc. when the spherical body 1 is pulled by a centrifugal force at the time of throwing, and the spherical body 1 and the string 4 do not fall out from the hole of the grip. It can also be used as a stopper.

  FIG. 4 is a left side sectional view of the pitching practice tool of the present invention. A spherical body 1, a mandrel 2 having a hole 2 a provided at one end, a ring 3, 3 ′, a string 4, a grip 5 having a through hole 5 a, a hole 1 a penetrating through the center of the spherical body 1, and a mandrel 2. It is comprised from the protrusion part 1b. The protruding portion 1b of the mandrel 2 is fitted toward the front side in the hole 1a penetrating the center of the spherical body 1. The diameter of the hole 1a formed at the center of the spherical body 1 is formed larger on the front side and smaller on the rear side. By forming the diameter of the hole 1a on the back side smaller than the diameter of the protrusion of the mandrel 2, the protrusion 1b of the mandrel 2 fits into the hole 1a and does not come off the spherical body 1. This is a structure for preventing the spherical body 1 from coming off the grip 5 and jumping out during the pitching practice.

  In FIG. 4, a hole 2a is formed on one end of the mandrel 2, and the hole 2a is connected to the spherical body 1 and the string 4 via the rings 3 and 3 '. It is also possible to connect the string 4 via the ring 2, and it is also possible to directly connect the hole 2a and the string 4 without using the rings 3, 3 '. When connecting the spherical body 1 and the string 4, it is important that the wrist that holds the spherical body 1 at the time of takeback or ball release is connected so that it can freely move 360 degrees back and forth and right and left. For example, by connecting two rings 3 and 3 ′ to the hole 2 a, there is a distance that allows the spherical body 1 to move freely between the spherical body 1 and the string 4, and the wrist can be held while holding the spherical body 1. You can move freely. When the rings 3 and 3 'are not used, the string 4 having high flexibility is directly passed through the hole 2a, and the spherical body 1 and the string 4 are connected. You can move and move your wrist freely.

  Also, the mandrel 2 in FIG. 4 can be adjusted in weight by changing the length, thickness, and shape. For example, there is a space portion 1a between the front side of the mandrel 2 and the surface of the spherical body 1, The amount of weight can be adjusted by determining the length of the mandrel 2 using the space portion 1a. Further, the back side of the mandrel 2 is fitted so as to protrude from the spherical body 1, a hole 2 a having a diameter larger than the diameter of the ring 3 is formed in the protruding portion, and the ring 3 and the string 4 are connected via the ring 3 ′. The body 1 and the grip 5 are connected. The grip 5 can be made of rubber, wood, synthetic resin, etc., and can be fixed without being moved. When the grip is fixed, it is formed by changing the ratio of the length of the ring-shaped portion A into which the arm and wrist are inserted, the grip 5, and the length of the string 4 protruding from the grip 5 toward the spherical body.

  In addition, when the mandrel 2 is fixed to the center of the spherical body 1 and the weight of the mandrel 2 is increased, the mandrel 2 serves as a weight, and the spherical body 1 is in front of the body in such a manner that the weight is led when throwing. It will be pulled to the state. By pulling the spherical body 1 forward, the arm extends straight forward at the same time, and the follow-through can be increased.

  FIG. 5 is a front view of the second embodiment of the spherical body 1 of the present invention. A spherical body 7, holes 8, 8 'formed in the spherical body 7, and a mandrel 9 provided with a hole 2a on one end side are constituted. The holes 8 and 8 'are formed in a cylindrical shape so that the fingers of the hand can be straightly inserted from the surface layer on the front side to the back side at a right angle to the mandrel 9, and the holes 8 and 8' are substantially parallel to each other. The holes 8 and 8 'are preferably provided on the center line of the spherical body. Holes 8 and 8 'are for practicing throwing with the 2nd and 3rd fingers of the hand. Since the holes are used for bending and stretching exercises with the fingers, the cross section of the hole is a perfect circle. However, the shape can be any shape such as an ellipse or a semicircle as long as the finger can be inserted.

  FIG. 6 is a front view of a third embodiment of the spherical body 1 of the present invention. A spherical body 10, a hole 11 formed in the spherical body 10, a mandrel 12, and a mandrel 12 having a hole 2 a provided on one end side are configured. The hole 11 can be cut from the surface layer on the front side to the back side so as to be perpendicular to the mandrel 12, and the hole 11 can be formed in an elliptical column shape so that several fingers can be inserted.

  FIG. 7 is a front view of a fourth embodiment of the spherical body 1 of the present invention. It consists of a spherical body 13, holes 14, 14 ′ formed in the spherical body 13, and a string 15.

  FIG. 8 is a side sectional view of the fourth embodiment of the spherical body 1 of the present invention. It consists of holes 14, 14 ', 14 "formed in the spherical body 13, a string 15, and a mooring portion 16. The spherical body 13 is formed by molding a material such as casting, iron, rubber or the like. Holes 14 and 14 'having a diameter enough to allow one string 15 to be inserted into the front surface of the spherical body 13, and holes 14 having a diameter enough to allow two strings 15 to be inserted into the back surface of the spherical body 13. Is formed so that two holes are seen when viewed from the front as shown in FIG. 7, and one hole is seen when viewed from the back as shown in FIG. The mooring part 16 of the spherical body 13 is formed, and the string 15 is inserted into the mooring part 16 so that the string 15 is hooked. The body 13 and the grip 5 can be connected.

  FIG. 9 is an example of use of the present invention. It consists of a spherical body 1 and a grip 5. Grasp the spherical body 1 and the grip 5, release the spherical body 1 at the release point, and then grip only the grip 5 and swing it all the way to the end. By grasping the grip 5 and swinging the arm with the centrifugal force, the follow-through increases, and the arm swings quickly. In addition, when the weight of the spherical body 1 is increased, the fingers 1, wrists, elbows, arms, shoulders, It can train the strength of the upper body such as the back muscles, and is also effective for warming up.

  FIG. 10 shows a usage example of the second embodiment of the spherical body of the present invention. It consists of a grip 5, a spherical body 7, and a hole 8. The second finger is put into the hole 8 of the spherical body, the third finger is put into the hole 8 ', and the grip 5 is grasped by the first finger, the fourth finger, and the fifth finger to perform the pitching operation. FIG. 10 is a diagram showing an intermediate position from the takeback to the release point. By holding the grip and throwing, the wrist can be thrown straight forward without bending, and the release point can be placed forward and slower than when throwing by holding a normal ball, slowing the release point be able to. By slowing down the release point, the swing trajectory becomes larger and you can practice pitching with weights on the lower body. By placing weight on the lower body, the lower body, which is the foundation necessary for throwing, is gradually trained, and a ball with increased ball power can be thrown.

  In addition, in order to train the finger pressure, grip strength, etc., which are indispensable for the pitcher, the fingers are gradually trained by throwing the fingers in the holes 8 and 8 'and pushing them out with the fingers using only the fingers. With this, you can train to reduce the decline in pressure due to a decrease in pressure to hold the ball and a decrease in grip strength.

  Also, when a finger is put into the holes 8 and 8 'of the spherical body 7 and taken back, the spherical body 1 is positioned tens of degrees behind the wrist than when the normal ball is gripped. The center of gravity of the spherical body 1 can be further placed behind the elbow, and the release point can be delayed by the distance that the center of gravity is behind. The slower the release point, the larger the trajectory for swinging the arm forward. The larger arm swing trajectory means that the distance that the ball is pushed from the takeback to the release point becomes longer, and the distance that the ball is pushed forward becomes longer. You can practice throwing a ball with the ball by putting your weight on the lower body to support your arms and upper body, and weight on your lower body.

  FIG. 11 is a usage example of the second embodiment of the spherical body of the present invention. It is composed of a spherical body 1, a string 4, a grip 5, and a hole 8. FIG. 11 is an operation following FIG. 10 and is a diagram immediately after the ball release. When the finger extends straight forward, the spherical body 1 is the position where the spherical body 1 comes out of the second and third fingers, which is the release point of the present invention. It is characterized in that the position at which the spherical body 1 is separated from the finger is later than the release point at which the normal ball is released. Further, when the side wall of the hole formed in the spherical body 1 comes into contact with the side surface of the finger, the point at which the spherical body 1 is separated from the finger is well understood, and the position of the release point can be grasped. Being able to accurately grasp the release point is suitable for practice of throwing a ball with stable control.

  FIG. 12 shows a change in the shape of the present invention. Before release, the ball is released, a after release, b, spherical body 1, string 4, grip 5, ring-shaped portion A for fixing the wrist, and grip movement distance B. a is the position of the grip 5 in a state of gripping the spherical body 1 before release from the takeback. b is the position of the grip 5 after release. After releasing the spherical body 1 from the finger, grasping the grip 5 and taking a follow-through posture, the string 4 moves away from the body by the centrifugal force and moves away from the body. Move to the side. In b, the distance from the wrist to the spherical body 1 is increased by the length of the distance B to which the grip has moved, the centrifugal force is stronger in the state of b than in the state of a, the swing speed is increased, and the follow-through is increased. . An increase in follow-through means that the arm swings faster and the ball speed increases when a normal ball is thrown.
