Description

  The present invention can practice swinging such as pushing a ball while receiving air resistance in baseball, tennis, badminton, golf, etc., and can also increase the number of swings by reducing vibration and impact. It relates to tools.

A swing exerciser that can feel the impact force, the hitting sound, the touch, and the realism as if they were actually hit in baseball, tennis, golf, etc. has been considered.
(For example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 08-024386 JP 2005-080912 A

  In Patent Document 1, although a good impact force, striking sound, feel and the like can be obtained, since the striking member has a short length, the feel of pushing the ball cannot be experienced.

  Further, in Patent Document 2, although good impact force, impact sound, feel, etc. can be obtained, when the striking member moves to the tip due to centrifugal force and inertia due to swinging, it is formed so that the hand side becomes heavier. As a result, it is possible to remove the force from the arms and elbows and perform a stable swing that does not shake the head. It was.

  In consideration of this point, the present invention considers this point, and in order to improve further, it is possible to feel the feel of pushing the ball with a bat when actually hitting the ball, and to further increase the number of swings. The purpose is to provide.

  In order to achieve the above object, the practice tool for swinging according to claim 1 is a shaft, a hit member at the tip of the shaft, a grip at the base end of the shaft, and a centrifugal force when gripping and gripping the grip. A striking member in a practice tool for swinging that has a striking member that moves to the tip side along the shaft due to force and inertia, and generates impact force and striking sound when the striking member moves and collides with the striking member The diameters of both ends in the axial direction are made smaller than the diameters other than both ends, and weights are attached to the inside of the shaft via joints.

  According to a second aspect of the present invention, the joint between the shaft and the weight is formed of a material that absorbs vibration and impact.

  The practice tool for swinging according to claim 3 is characterized in that there are one or more joint portions, and the shaft and the weight are formed so as not to contact except for the joint portions.

  The swing exercise tool according to claim 4 is characterized in that the weight is attached to any location from the distal end side to the proximal end side of the shaft.

  The swing exercise tool according to claim 5 is characterized in that the hitting member is wood.

  In the above-described swing exercise tool of the present invention, the striking member is formed in a long shape so as to receive the resistance of air by swinging, so that the air like when a ball is hit during swinging is formed. A feeling of weight is added by the resistance, and an excellent effect that the feeling of pushing the ball with the bat can be exhibited.

  Also, by making the diameter of both ends of the striking member smaller than the diameter of the other part, the person who swings can press and release the striking member with his / her finger, so the hitting point where the ball is to be hit is determined by himself The excellent effect of being able to be able to be exhibited can be exhibited.

  In addition, by forming the connecting part of the inner wall and the weight in the shaft with an elastic member that absorbs vibration and shock, when the striking member collides with the hit member, the weight and vibration are not easily transmitted to the weight. Because the vibration and shock are not easily transmitted, the weight can be kept independent. By keeping the weights independent, the weights can perform their own movements. When swinging, the centrifugal force acting on the practice tool for swinging and the centrifugal force acting on the weight alone appear, resulting in a stronger centrifugal force. It is possible to demonstrate the excellent effect of increased work-follow-through.

  In addition, the striking member collides with the striking member during swinging and gives vibration and impact. It is possible to demonstrate an excellent effect that the number of vibrations can be reduced and many practice exercises can be performed.

  In addition, since the striking member is made of wood, it can be formed lighter than Patent Documents 1 and 2, so that even if the striking member collides with the striking member due to swinging, the load such as vibration and impact is small. It is possible to swing out lightly with one hand from the impact, and to exhibit an excellent effect of being able to shift to a large follow-through.

Best Mode for Invention

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. However, the present invention is not limited by the present embodiment, and the following embodiment is described as an example of the practice tool for swinging of the present invention, and is limited to the content of this description. is not.

  FIG. 1 is a perspective view of a practice tool for swinging according to the present invention. The practice tool for swinging according to the present invention includes a shaft 1, a striking member 2, both end portions 2 ′ of the striking member, a striking member 3, and a grip 4.

  The striking member 2 is formed in a shape that is susceptible to air resistance. The longer the striking member 2 is, the easier it is to receive air resistance, and it is possible to obtain air resistance as when a ball is hit with a bat. It is possible to obtain a sense of resistance as if the bat was weighted, and to feel the feeling of pushing the ball with the bat.

  Further, since the diameters of both end portions 2 'of the striking member 2 are reduced, when the striking member collides with the hit member, the collision area becomes small so that the ball hits the bat core and hits the bat core. You can get the feeling of feeling the weight.

  FIG. 2 is a right side view of the practice tool for swinging according to the present invention. It comprises a shaft 1, a striking member 2, both end portions 2 ′, a striking member 3, a grip 4, a joint portion 5, and a weight 6. The weight 6 in FIG. 2 is an example attached to the tip end side of the shaft.

  FIG. 3 is an enlarged view of a portion where the weight 6 is attached to the shaft 1 via the joint 5. The shaft 1, the joint 5, the weight 6, and the space 7 are configured. The joint 5 is attached so as to be wound around the weight 6 while providing a space 7 using an elastic body that absorbs vibration and impact. Thus, the vibration and impact generated when the striking member 2 collides with the striking member 3 during swinging can be absorbed, and the weight 6 functions independently because the vibration and impact are not transmitted to the weight 6. Can do. When the weight 6 moves independently, the centrifugal force of the practice tool for swinging according to the present invention and the centrifugal force of the single weight of the weight 6 are added and amplified to further increase the centrifugal force and the strong centrifugal force. The torsion of the body is increased and a large follow-through can be obtained.

  Further, due to the presence of the space 7 and the joint portion 5 using an elastic body, the weight 6 and the practice tool for swinging according to the present invention are less likely to resonate with each other. Even if you practice swinging, you can reduce the vibration and shock transmitted to your hands and arms and increase the number of swings.

  FIG. 4 is a perspective view in which the striking member 2 of the practice tool for swinging according to the present invention is positioned on the grip 4 side. The shaft 1 is composed of a striking member 2, a striking member 3, and a grip 4.

  FIG. 5 is a comparison of the movement distances of the practice tool for swinging of the present invention and the striking member of Patent Documents 1 and 2. A of A is the moving distance of the striking member of the practice tool for swinging according to the present invention, and b of B is the moving distance of the striking member of Patent Documents 1 and 2. The moving distance of a is short and the moving distance of b is long. The reason why the movement distance of the striking member is shortened is that the body can be swung as much as possible using the torsion of the body. Performing a swing using body torsion means that a compact swing can be performed, and is intended to avoid swinging without using the torsion of the body, which is said to be a hand swinging with only an arm. By swinging with the torsion of the body, the force is effectively transmitted to the hit ball and a powerful hit becomes possible.

  FIG. 6 is a diagram of performing swinging with the swing training tool of the present invention. Since the movement distance of the striking member is short, training of swinging to push forward using torsion of the body can be performed.

  Although the present invention describes a baseball practice tool that generates impact force and impact sound, it can be formed into a shape such as a tennis or badminton racket, a golf club, or the like. .
