The present invention relates to a baseball bat having an internal moving member.

In general, the swinging posture using a baseball bat is subdivided into an address, a swing top, a down swing, an impact, a follow through, and a finish.

In particular, if you try to blow a long distance by hitting a baseball or a strong hitting a baseball bat over the shoulder and then hit the baseball bat hard to hit the baseball ball.

In this case, the distance of the baseball depends on the speed and force of the baseball player's rotation of the baseball, but basically the distance of the baseball is determined by the distance at impact. Posture and speed play an important role.

As a device for correcting the address posture and the speed of the impact, Korean Patent Registration Publication No. 10-0465781 'Baseball Bat' was devised.

Baseball bats as above is to install a weight inside the bat (30) inside, and to practice by correcting the position of the weight each time you practice.

Such a device allows the bettor to be able to detect the change in the center of gravity quickly and practice the swinging posture.

In other words, as far as baseball bats are concerned, the postures were not particularly corrected and the swing speed could not be adjusted.

Baseball bat having an internal moving member of the present invention is intended to solve this problem, simply forming a moving passage in the baseball bat, and inserting the moving member to move freely according to gravity or swing inside the moving passage when batting practice The purpose is to learn the correct swing posture and swing speed through the sound, vibration of the moving member according to the rotational speed and the phase of the bat.

In addition, there is a purpose to increase the practice effect through the sound of moving a plurality of moving members by installing a plurality of partitions.

In addition, it has a purpose to form a structure that can check the inside of the moving passage to enhance the practice effect.

In addition, there is also an object to check the inside and at the same time to form a moving member as a luminous member to enhance the visual practice effect at night.

The present invention relates to a baseball bat having an internal moving member.

The present baseball bat is formed with a moving passage therein, and a moving member is inserted into the moving passage to correct the swing posture through the sound and vibration of the moving member according to the swing.

In addition, by installing a plurality of partitions to enhance the practice effect through the sound of the movement of several moving members.

In addition, it is formed to a structure that can check the inside of the moving passage to increase the practice effect.

In particular, it is possible to check the inside and at the same time to form a moving member as a luminous member to enhance the visual practice effect at night.

Baseball bat having an internal moving member of the present invention for this purpose, the body is formed with a moving passage in the longitudinal direction therein; It is composed of; a moving member for moving the inside of the moving passage of the body.

Baseball bat having an internal moving member of the present invention is to move the moving member is always constant by making the width of the moving passage constant.

In addition, the baseball bat having an internal moving member of the present invention is a part of the body surrounding the moving passage is transparent so that the inside can be confirmed.

In particular, the moving member is formed as a luminous member in a configuration to check the inside, so that it is possible to practice effectively at night.

Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

However, the accompanying drawings are only one example for illustrating the technical idea of the present invention in more detail, and thus the technical idea of the present invention is not limited to the accompanying drawings.

Body 10, which is a component of the present invention, has a moving passage 11 formed in the longitudinal direction therein.

The body 10 is made of wood or aluminum, like baseball bats that are commonly used.

At this time, unlike the general baseball bat it is preferable to form the internal movement passage 11 to form the same as the actual baseball bat using the inner material and the center of gravity so that the change in the center of gravity does not occur.

The moving passage 11 formed inside the body 10 has a constant width to enable a smooth and constant movement of the member moving the passage.

Various embodiments of the method of forming the moving passage 11 inside the body 10 are illustrated in FIGS. 2, 3, 4, and 5.

First, FIG. 2 and FIG. 3 have a structure in which the inside is formed in an empty form when the initial body 10 is formed in the simplest form, and the cap 12 is covered only in the opening part.

In addition, although not shown, it is possible to form the moving passage 11 without installing the cap 12 by a method such as welding or internal insertion in the initial processing step.

4 has the advantage of installing a plurality of partitions and a plurality of moving objects therein as shown in FIG. 5 when the moving passage case 13 is installed in the body 10.

Although not shown, a groove may be formed in the inner wall surface of the body 10 forming the moving passage 11 without installing the moving passage case 13, and the partition may be formed and inserted into a member having elasticity. .

In the above, all baseball bats having a form in which an object can move in addition to those described will be included in the technical idea of the present invention.

In addition, the body 10 of the present application may be to check the mobile passage 11 in the outside.

To this end, one side of the body 10 may be formed of a transparent member 14 such as a transparent plastic or a transparent member 14 may be installed.

The moving member 20 which is a component of the present invention is installed inside the moving passage 11 of the body 10 so as to move the moving passage 11 freely.

The preferred shape of the moving member 20 is not limited to a spherical shape, but may be formed in a suitable shape according to the shape of the disk or the cross-sectional shape of the moving passage 11.

In addition, the material of the movable member 20 may be formed of various materials such as glass, plastic, and metal.

The moving member 20 is not to be pinched in the moving passage 11 is to be able to move freely.

Therefore, it is preferable to set the size of the movable member 20 to have a gap between the movable member 20 and the movable passage 11 as small as 0.1 mm to about 5 mm.

Looking at Figure 7 it can be seen that the moving member 20 is located at the bottom of the moving passage (11).

The moving member 20 is not in a state of swinging the baseball bat, that is, in the state in which the body 10 is fixed, and is positioned at the lowest position under the influence of gravity, and the moment the user swings the baseball bat, the effect of centrifugal force and gravity The position in the movement passage 11 is determined according to the influence.

As described above, the movable member 20 is formed as a luminous member when the transparent member can check the inside of the movable passage 11, so that the movable member 20 moves in the movable passage 11 during the night swing. You can also check.

Referring to the operation of the present invention configured as described above with reference to Figures 7 to 11 as follows.

7 illustrates a state in which the user takes a baseball bat and takes a swing ready position, that is, an address posture.

At this time, the body 10 is perpendicular to the ground or inclined state, the moving member 20 is located at the end of the handle side movement passage 11 by the influence of gravity.

FIG. 8 illustrates a time when the user starts the swing and the baseball bat starts to move. The moving member 20 at the end of the handle starts moving to the opposite side of the movement path 11 by the centrifugal force generated during the swing. .

9 shows the state at impact, the moving member 20 is located at the end of the movement passage 11 on the opposite side of the handle.

Figure 9 shows the body 10 when passing through a plane parallel to the ground at the time of impact using a baseball bat of the present invention.

That is, when the angle of the body 10 exceeds 90 degrees from the light perpendicular to the ground.

When the impact is normally fast, the moving member 20 moves quickly to the end of the moving passage 11 on the opposite side of the handle, and informs the user that the impact has been hit with the sound of 'taking'.

At this time, the body 10 and the ground is close to the parallel state.

On the other hand, if the impact at a slow speed the moving member 20 does not move from the handle side end of the movement passage 11 to the opposite end of the handle.

That is, when the impact swinging body 10 passes through a plane parallel to the ground, the moving member 20 quickly rolls the sound, so that the impact point can be known and the posture and swing speed can be corrected at impact.

On the other hand, as shown in Fig. 10, 11 when the finish after passing through the impact point when the moving member 20 moves to the end of the moving passage 11 of the handle side and the user with the sound of 'taking' eventually You will be informed that all swing moves are complete.

In the case of the palos-ru and the finish motion, as well as the impact, when the user swings at a slow speed, the moving member 20 rolls and vibrates to make the user recognize that he is making a wrong swing.

The baseball bat configured as described above is preferably used during practice, and it is also effective to be used in practice and practice games at night with a ball made of luminous.

In the baseball bat of the present invention, if the metal member or the wall surface is formed of a metal inside the moving passage, and the moving member is formed of a magnet can feel the sprinkling during the follow swing by the magnetic force is more effective.

According to the present invention, simply forming a moving passage inside the baseball bat, and inserting the moving member to move freely according to gravity or swing inside the moving passage, the sound of the moving member according to the rotational speed and the phase of the bat during the batting practice By vibrating, you can learn the correct swing posture and swing speed.

In addition, by installing a plurality of partitions, the practice effect is increased through the sound of the movement of several moving members.

In addition, it is formed into a structure that can confirm the inside of the moving passage, the practice effect is increased.

In addition, by allowing the inside to be checked, the moving member is formed as a luminous member, thereby increasing the visual practice effect at night.
