Description

The present invention relates to an instrument used for practicing a game of hitting a ball with a bat or the like, and more particularly to an instrument for hitting a ball, which is preferably used for practicing baseball tee batting.

There is tee batting as a basic batting practice method in baseball. There are two ways to do this, one is to practice hitting the ball with the toss raised by the assistant toward the net, and the other is to hit the ball placed on the tip of an upright rod-shaped member called a so-called tea stand. It is said to be effective for learning.

On the other hand, there is an opinion that the former practice method is not practical and the latter practice method is effective because it hits a ball tossed from a direction different from the direction thrown from the pitcher. This method has the advantage that since the position of the ball is fixed, batting practice can be performed according to the height and course of the ball, and toss is not required, so that the player can practice alone.

As a prior art relating to the latter, Patent Document 1 has a rod-shaped tee in which the hollow portion of the outer shell member is slidably arranged, and the tee can be fixed at an arbitrary position in the height of the outer shell member. A stand device for tea batting provided with the above is disclosed.

Japanese Unexamined Patent Publication No. 2012-000417

In addition to this, several similar batting tee stands have been disclosed, but the practice method using these instruments is to hit the ball placed on the tip toward the separately installed net. It is necessary to collect the hit ball, so-called ball picking. Therefore, there is a problem that the efficiency of practice is lowered.

There is also a practice method of hitting a ball that is hung by joining a string in order to eliminate the need for picking up the ball, but in this case, it is necessary to stop the hit ball each time. Furthermore, there is room for improvement in the sense that it is not always sufficient to master the batting form of downswing and level swing, whether using a tee stand or a suspended ball.

The present invention has been made as a result of studying the improvement of the conventional tea stand in order to solve the above-mentioned problems.

One embodiment of the present invention comprises a pedestal, a strut having a ball mounting portion that is vertically planted on the upper surface of the pedestal, has a hollow portion, and is provided in an opening at the upper end. A ball striking practice device comprising an elastic string having one end joined to the lower end of the hollow portion of the support and the other end joined to the ball.

Further, one embodiment of the present invention has a coil-shaped tension spring having one end joined to the lower end of the hollow portion, and the other end of the coil-shaped tension spring has the elasticity. The ball striking practice device, characterized in that it is joined to the one end of the string to be held.

Further, in one embodiment of the present invention, a rod-shaped member is attached to an arbitrary position of the support column in the vertical direction of the support column, and the rod-shaped member is attached to the tip of the rod-shaped member in a direction parallel to the support column. The above-mentioned ball striking practice device is characterized by being provided with an elastic vertical rod-shaped member.

In the ball striking practice device according to the present invention, a ball joined to a stretchable string, one end of which is joined to the lower end of the strut, is placed on the upper end of the strut and hit. , It will return to the original position, so you can continue practicing.

Also, in general, in the form of a bat swing, compared to a downswing or a level swing, the upper swing is often instructed to be modified for the following reasons. (1) The possibility of meeting is lower than hitting the ball with a level swing. (2) It is difficult to hit a high ball. (3) Compared to a downswing or a level swing, the bat turns a lot, so a swing delay is likely to occur.

In the ball striking practice device according to the present invention, after passing over an elastic vertical rod-shaped member provided near the ball mounting portion, the bat is swung so as to hit the ball, thereby forming an upper swing. You can learn bat control.

The front view of an example of the ball striking practice device of this invention.

FIG. 1 is a front view of an example of a ball striking practice device of the present invention, and shows a partial cross section. The example shown here has a pedestal 5 and a support column 6 planted perpendicular to the pedestal 5, the support column 6 has a hollow portion in the center, and a base portion 6c formed by being directly joined to the pedestal 5 and a base portion. An intermediate portion 6b that is slidably arranged in the hollow portion of 6c and has a hollow portion and a top portion 6a that fits on the outer peripheral side of the intermediate portion 6b are constituent elements. Has an enlarged ball mounting portion 4. The pedestal 5, the base 6c, and the intermediate portion 6b can be made of metal, plastic, or the like, but it is desirable to use a soft material such as a rubber hose for the top 6c, assuming the impact of the bat hitting.

A coil-shaped tension spring 3 is arranged at the bottom of the base 6c of the support column 6, the lower end in the drawing of the tension spring 3 is joined to the pedestal 5, and the upper end is an elastic string, here. The elastic cord 2 is joined. A ball 1 is attached to the upper end of the rubber cord 2 in the drawing. The intermediate portion 6b of the support column 6 is slidably arranged in the hollow portion of the base portion 6c, and is fixed by a second fixing means 8b made of a thumbscrew. With such a configuration, the height of the support column 6 can be adjusted within a certain range.

The ball 1 can also be used as a normal baseball ball, but here, a ball 1 having a hollow inside, which is the size of a golf ball, is joined to the tip of a rubber cord 2. By using a small-diameter ball and narrowing the range of the bat's meet, you can learn accurate bat control. Also, for the same purpose, the effect of practice can be increased by using a bat that has almost the same weight as a normal bat and has a smaller outer diameter.

The ball 1 attached in such a state returns to its original position by the action of the rubber cord 2 and the tension spring 3 regardless of whether it is struck or flies, so catch it appropriately and place it on the ball mounting portion 4. You can place it and continue practicing. The tension spring 3 reinforces the action of the rubber cord 2, and eliminates the tension spring 3 so that, for example, a means for joining the lower end of the rubber cord 2 at an appropriate position in the figure of the rubber cord 2 is provided. As a matter of course, the structure is simplified and the work of assembling and disassembling becomes easy.

Further, the form of the bat swing is preferably a level swing or a downswing as described above, but in the ball striking practice device according to the present invention, as shown in FIG. 1, it is composed of thumbscrew attached to the support column 6. Since the vertical rod-shaped member 10 attached to the support column 6 is provided by the first fixing means 8a in a state where it can be slid in the vertical direction in the drawing in a certain range, a bat (FIG. 1) is provided from right to left in FIG. Practice level swing and downswing batting forms by swinging (not shown) so that the trajectory of the bat draws between the top of the vertical rod-shaped member 10 and the ball 1 when hitting the ball 1. can.

It is desirable that the vertical rod-shaped member 10 is made of soft rubber or the like in preparation for danger when the bat hits it. The rod-shaped member 10 is attached to the tip of the rod-shaped member having a bent portion attached via the joining annular member 7, and the height difference between the rod-shaped member 10 and the ball 1 can be adjusted.

As described above, according to the present invention, it is possible to provide a batting practice device capable of continuously practicing a bat swing with a simple structure. The present invention is not limited to the above-described embodiment, and can be conceived by a person having ordinary knowledge in the field of the present invention, for example, omitting a tension spring as described above. Of course, even if there is a design change within a range that does not deviate from the gist of the present invention, including various modifications and modifications, it is included in the present invention.
