Description

[Detailed Description of the Invention] The present invention relates to a batting practice tool for practicing batting in baseball.

Conventional batting practice equipment has a structure in which a retractable support made of metal is attached to the home base, and a rubber rod on which a ball can be placed can be attached replaceably to the top of the support.

Batting training equipment constructed in this manner has the following drawbacks.

(1) The strut structure is complicated and costly.

(2) The ball is supported by a rubber rod, so if you place the ball on the rubber rod, you must be careful or it will easily fall off.

(3) Tools such as spanners are required to replace the rubber rod, which is cumbersome.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the conventional art, the present invention aims to provide a batting practice tool that is simple in structure, easy to place balls on, and inexpensive.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

In the embodiments shown in FIGS. 1 and 2, reference numeral 1 denotes a base plate made of a metal plate, and approximately in the center of this base plate 1 is a circle in which a fitting part 2 is formed with a small diameter at the top. A columnar support member 3 is fixed by welding or the like. Reference numeral 4 denotes a home base that covers the base plate 1, and a through hole 5 through which the support member 3 passes is formed approximately at the center of the home base 4. Reference numeral 6 denotes a cylindrical first tube made of a flexible material such as rubber or vinyl, and the lower end of the first tube 6 is fitted and fixed to the fitting portion 2 of the support member 3. A coil spring 7 is screwed into and fixed to the upper part of the first tube 6. 8 is a cylindrical second tube made of flexible material such as rubber or vinyl;
The lower end of the second tube 8 is screwed into and fixed to the upper end of the coil spring 7, and a ball 9 is placed on the upper end.

In the above configuration, when practicing batting, a coil spring 7 is interposed between the first tube 6 and the second tube 8. After that,
The lower end of the first tube 6 is connected to the fitting part 2 of the support member 3.
Fit and fix. In this state, a ball 9 is placed on the top of the second tube 8, and the ball is hit with a bat for practice.

When practicing batting, the height of the ball can be adjusted by arbitrarily setting the dimensions between the first and second tubes 6 and 8 of the coil spring 7 interposed between the first and second tubes 6 and 8. You can practice batting. Adjusting the height is the first step.
This can be easily adjusted by adjusting the screwing condition between the second tube 6 and the coil spring 7 or the screwing condition between the second tube 8 and the coil spring 7.

Next, different embodiments of the present invention shown in FIGS. 3 to 5 will be explained. In the description of these embodiments, the same parts as those of the embodiments of the present invention are given the same reference numerals and redundant explanations will be omitted.

In the embodiment shown in FIG. 3, the main difference from the embodiment of the present invention is a support member 3A, which is fixed to the base plate 1 and has a threaded portion 1 on the upper inner wall.
A cylindrical support member main body 11 having a diameter 0 formed thereon, and a fitting member 13 into which a cylindrical first tube 6 having a threaded portion 12 that is threadedly engaged with the threaded portion 10 of this support member main body 11 is fitted. It consists of In the case of a device configured in this way, when the fitting member 13 of the support member 3A is removed during carrying or transportation, the height becomes the same as that of the base plate 1 and the support member main body 11, and the height is reduced. It can be carried and packed smaller.

The main difference between the embodiments shown in FIGS. 4 and 5 from the embodiment of the present invention is that the base plate 1A is formed in the shape of a home base. By configuring the base plate 1A in this way, the home base becomes unnecessary. Cost reduction can be achieved. Note that rubber or the like may be fixed onto the base plate 1A using an adhesive or the like.

As is clear from the above description, the present invention has the following effects.

(1) Since the first and second tubes are made of a flexible material such as rubber or vinyl, they are available at low cost and can reduce costs.

(2) Since a coil spring is interposed between the first and second tubes, it is possible to efficiently prevent the impact applied to the first tube during batting practice from being transmitted to the base plate, and it is durable. can improve sex.

(3) Assembling and disassembling is extremely easy because it is sufficient to interpose a coil spring in the first and second tubes and to fit the first tube into the support member.

(4) The height can be adjusted very easily by changing the length of the fit between the first tube and the coil spring or the length of the fit between the second tube and the coil spring.

(5) The structure is simple and inexpensive.

(6) The first tube and the second tube with the coil springs interposed therebetween can be removed from the support member, making it convenient to carry.

(7) Since the height can be adjusted arbitrarily according to (4) above, there is no need for a conventional locking mechanism that locks the butterfly screw or sliding rod at an arbitrary position, so the number of parts can be reduced. Therefore, it is possible to reduce costs.
