Below, based on FIGS. 1-4, the ball game training tool A of Embodiment 1 of this invention is demonstrated.
As shown in FIG. 1, which is a perspective view of the ball game training tool A of the first embodiment, the ball game training tool A includes an elastic net member (elastic net-like member) 10, a support frame 20, and leg members 30.

弾性ネット部材１０は、図２に示すように、網状に形成された本体部１１と、この本体部１１の外周部から外径方向に放射状に延びる紐状に形成された複数の連結用ライン部（連結用紐状部）１２と、を備える。 As shown in FIG. 2, the elastic net member 10 includes a main body portion 11 formed in a net shape and a plurality of connecting line portions formed in a string shape extending radially from the outer peripheral portion of the main body portion 11 in the outer diameter direction. (A string-like portion for connection) 12.

本体部１１は、天然ゴム、合成ゴムなどにより形成された細紐状の弾性材によりハニカム状に一体成形され、かつ、全体形状が円形に近い略多角形状（本実施の形態１では、１２角形状に近い形状）を成すように形成されている。
さらに、本体部１１の外周部分は、ハニカム同士をハニカムの１／２の形状の部分で連結した第１の連結部１１ａと、ハニカムの１つの角部を省略した５角形状として連結した第２の連結部１１ｂとが、周方向に交互に配置され、合計で１２箇所に両連結部１１ａ，１１ｂが設けられている。The main body 11 is integrally formed in a honeycomb shape with a thin string-like elastic material formed of natural rubber, synthetic rubber, and the like, and the overall shape is a substantially polygonal shape (in the first embodiment, 12 corners). A shape close to the shape).
Furthermore, the outer peripheral part of the main body part 11 is connected to the first connecting part 11a in which the honeycombs are connected to each other by a half-shaped part of the honeycomb, and the second connecting part in a pentagonal form in which one corner part of the honeycomb is omitted. The connecting portions 11b are alternately arranged in the circumferential direction, and the connecting portions 11a and 11b are provided at 12 locations in total.

連結用ライン部１２は、各連結部１１ａ，１１ｂの周方向の中央位置から外径方向に延在されており、本体部１１の外周の１２箇所に周方向で等間隔に設けられている。
そして、連結用ライン部１２は、細紐状のライン部本体１２ａと、ライン部本体１２ａにおいて延在方向に等間隔で配置されてライン部本体１２ａよりも大径の球状に形成された複数（本実施の形態１では４つ）の係止突起部１２ｂと、を備える。The connecting line portion 12 extends in the outer diameter direction from the center position in the circumferential direction of each of the connecting portions 11a and 11b, and is provided at twelve positions on the outer periphery of the main body portion 11 at equal intervals in the circumferential direction.
The connecting line portion 12 has a thin string-like line portion main body 12a and a plurality of (in a spherical shape having a larger diameter than the line portion main body 12a, which are arranged at equal intervals in the extending direction of the line portion main body 12a. In the first embodiment, there are four) locking projections 12b.

支持枠２０は、本実施の形態では、図３に示すように、円環状に形成されており、金属、樹脂、木材などにより形成されている。また、本実施の形態１では、支持枠２０は、周方向に三分割された分割枠２０ａ，２０ｂ，２０ｃを、それぞれ、周方向の端部同士を突き合わせて結合して形成されている。 In the present embodiment, the support frame 20 is formed in an annular shape as shown in FIG. 3 and is formed of metal, resin, wood, or the like. In the first embodiment, the support frame 20 is formed by joining the divided frames 20a, 20b, and 20c, which are divided into three in the circumferential direction, with their end portions in the circumferential direction butted together.

さらに、支持枠２０の外周部には、円周方向に等間隔で１２箇所に、支持枠２０の円弧の中心軸に沿う方向に延在された縦溝２１が形成されている。この縦溝２１は、溝幅が、ライン部本体１２ａの直径寸法程度であって係止突起部１２ｂより幅狭に形成されているとともに、外径側の開口部分が、ライン部本体１２ａの直径よりも幅を狭く形成されている。そして、縦溝２１の下端部の外周縁部の支持枠２０の下端面が、係止突起部１２ｂを前記中心軸に沿う方向に係止させることができるストッパ部２２とされている。 Further, on the outer peripheral portion of the support frame 20, longitudinal grooves 21 extending in the direction along the central axis of the arc of the support frame 20 are formed at 12 positions at equal intervals in the circumferential direction. The vertical groove 21 has a groove width that is about the diameter of the line portion main body 12a and is narrower than the locking projection 12b, and an opening portion on the outer diameter side has a diameter of the line portion main body 12a. The width is narrower than that. And the lower end surface of the support frame 20 of the outer peripheral edge part of the lower end part of the vertical groove 21 is made into the stopper part 22 which can latch the latching protrusion part 12b in the direction along the said central axis.

図１に戻り、脚部材３０は、支持枠２０を、所定の高さに保持するものであり、支持枠２０の周方向の３以上の複数箇所であって、実施の形態１では３箇所に等間隔で設けられている。
この脚部材３０は、金属製のブラケット部３１および脚本体３２と、発泡弾性材製のカバー材３３とを備える。
ブラケット部３１は、薄板状の第１片３１ａと第２片３１ｂとにより略Ｌ字断面形状に形成されている。そして、第１片３１ａを、支持枠２０の各分割枠２０ａ，２０ｂ，２０ｃの結合個所において分割枠２０ａ，２０ｂ，２０ｃに跨って支持枠２０の下面に沿わせて配置し、跨る両分割枠に螺子などで固定されている。したがって、ブラケット部３１は、支持枠２０に脚部材３０を固定するとともに、分割枠２０ａ，２０ｂ，２０ｃの隣り合うもの同士を結合する結合部材を兼ねている。Returning to FIG. 1, the leg member 30 holds the support frame 20 at a predetermined height, and there are three or more places in the circumferential direction of the support frame 20. It is provided at equal intervals.
The leg member 30 includes a metal bracket portion 31 and a leg main body 32, and a cover material 33 made of foamed elastic material.
The bracket portion 31 is formed in a substantially L-shaped cross section by a thin plate-like first piece 31a and a second piece 31b. And the 1st piece 31a is arrange | positioned along the lower surface of the support frame 20 straddling the division frames 20a, 20b, and 20c in the joining part of each division frame 20a, 20b, 20c of the support frame 20, and both division frames which straddle It is fixed with screws. Therefore, the bracket portion 31 serves as a coupling member that fixes the leg members 30 to the support frame 20 and couples adjacent ones of the divided frames 20a, 20b, and 20c.

脚本体３２は、上端部を前記ブラケット部３１の第２片３１ｂに螺子等により固定され、ブラケット部３１から下方に延在されている。 The leg main body 32 has an upper end fixed to the second piece 31 b of the bracket portion 31 by a screw or the like, and extends downward from the bracket portion 31.

カバー材３３は、発泡弾性材により形成され、脚本体３２の下端部の外周に装着され、脚部材３０から本球技練習具Ａを載置した床や地面などへの振動の伝達を抑制する。なお、発泡弾性材としては、発泡ゴム、発泡プラスチック（ＰＵフォーム、ＰＥフォーム、ＰＶＣフォームなど）を用いることができる。
また、カバー材３３は、側方から見た形状が円錐状に形成され、底面３３ａの面積が、脚本体３２の断面積よりも広く確保されている。The cover member 33 is formed of a foamed elastic material, and is attached to the outer periphery of the lower end portion of the leg main body 32, and suppresses transmission of vibration from the leg member 30 to the floor or the ground on which the ball game training tool A is placed. As the foamed elastic material, foamed rubber and foamed plastic (PU foam, PE foam, PVC foam, etc.) can be used.
Further, the cover member 33 is formed in a conical shape when viewed from the side, and the area of the bottom surface 33 a is secured wider than the cross-sectional area of the leg body 32.

次に、前述の弾性ネット部材１０の支持枠２０への取付構造について説明する。
弾性ネット部材１０は、中心から連結用ライン部１２の先端位置までの寸法（図２のＬｒに示す寸法）が、自然長で、支持枠２０の内径寸法程度の大きさに形成されており、弾性ネット部材１０を外径方向に伸長させた展張状態で、支持枠２０に連結支持されている。Next, a structure for attaching the elastic net member 10 to the support frame 20 will be described.
The elastic net member 10 has a natural length (dimension indicated by Lr in FIG. 2) from the center to the tip position of the connecting line portion 12 and is formed to have a size approximately equal to the inner diameter of the support frame 20. The elastic net member 10 is connected and supported by the support frame 20 in a stretched state in which the elastic net member 10 is extended in the outer diameter direction.

すなわち、各連結用ライン部１２をそれぞれ引張状態として支持枠２０の縦溝２１に連結することで、弾性ネット部材１０を全体的に伸長し、ボールを跳ね返すための弾性力が与えられる。
詳細には、図４に示すように、弾性ネット部材１０の各連結用ライン部１２のライン部本体１２ａを、支持枠２０の縦溝２１に挿通するとともに、係止突起部１２ｂを、ストッパ部２２に係止することで、連結用ライン部１２が支持枠２０に連結されている。図４に示す例では、各連結用ライン部１２は、先端側から３番目の係止突起部１２ｂが支持枠２０の下面のストッパ部２２に係止されている。なお、連結用ライン部１２のライン部本体１２ａを縦溝２１に挿通する際には、連結用ライン部１２を、伸長させて直径が細くなるように弾性変形させた状態で、縦溝２１の開口部分を通過させる。That is, by connecting the connecting line portions 12 to the longitudinal grooves 21 of the support frame 20 in a tension state, the elastic net member 10 is stretched as a whole, and an elastic force for rebounding the ball is applied.
Specifically, as shown in FIG. 4, the line portion main body 12 a of each connecting line portion 12 of the elastic net member 10 is inserted into the vertical groove 21 of the support frame 20, and the locking projection portion 12 b is inserted into the stopper portion. The connecting line portion 12 is connected to the support frame 20 by being locked to the support 22. In the example shown in FIG. 4, in each connecting line portion 12, the third locking projection 12 b from the tip side is locked to the stopper portion 22 on the lower surface of the support frame 20. In addition, when inserting the line part main body 12a of the connecting line part 12 into the longitudinal groove 21, the connecting line part 12 is stretched and elastically deformed so that the diameter becomes narrower. Let the opening pass.

また、縦溝２１の下端のストッパ部２２に係止させる係止突起部１２ｂの位置を変えることにより、弾性ネット部材１０の弾性力を段階的に調整することができる。
すなわち、支持枠２０の下面のストッパ部２２に係止する連結用ライン部１２の係止突起部１２ｂを、図４に示す状態から、その先端側から２番目あるいは１番目の係止突起部１２ｂに変更することにより、弾性ネット部材１０の弾性力を緩めることができる。逆に、支持枠２０の下面のストッパ部２２に連結用ライン部１２の先端側から４番目の係止突起部１２ｂとすることにより、弾性ネット部材１０の弾性力を強めることができる。Moreover, the elastic force of the elastic net member 10 can be adjusted stepwise by changing the position of the locking projection 12b to be locked to the stopper 22 at the lower end of the vertical groove 21.
That is, the locking protrusion 12b of the connecting line portion 12 locked to the stopper portion 22 on the lower surface of the support frame 20 is the second or first locking protrusion 12b from the distal end side from the state shown in FIG. By changing to, the elastic force of the elastic net member 10 can be loosened. Conversely, by making the stopper portion 22 on the lower surface of the support frame 20 the fourth locking projection 12b from the distal end side of the connecting line portion 12, the elastic force of the elastic net member 10 can be increased.

また、この弾性ネット部材１０における支持枠２０との係合状態は、全周で同一とすることに限定されるものではなく、周方向の場所により異なる係合状態とすることにより、上述の弾性ネット部材１０の弾性力を、さらに微調整することも可能である。例えば、連結用ライン部１２の係合状態を、支持枠２０の下面のストッパ部２２に係止する連結用ライン部１２の係止突起部１２ｂを、先端側から３番目としたものと４番目としたものとを交互に配置することで、弾性力を微調整することができる。このようにして、弾性ネット部材１０の弾性力を、使用するボールの弾性力に近い弾性力に設定することができる。 Further, the engagement state of the elastic net member 10 with the support frame 20 is not limited to being the same over the entire circumference, and the above-described elasticity can be achieved by changing the engagement state depending on the location in the circumferential direction. The elastic force of the net member 10 can be further finely adjusted. For example, the engaging state of the connecting line portion 12 is set such that the engaging protrusion 12b of the connecting line portion 12 that engages with the stopper portion 22 on the lower surface of the support frame 20 is the third from the tip side and the fourth. The elastic force can be finely adjusted by alternately arranging the above. In this way, the elastic force of the elastic net member 10 can be set to an elastic force close to the elastic force of the ball used.

次に、実施の形態の作用を説明する。
（使用時）
球技練習具Ａは、脚部材３０のカバー材３３の底面３３ａを、床、地面などに接触させ、支持枠２０および弾性ネット部材１０を、床、地面などから浮かせた状態として使用する。
この状態で、図外のバスケットボールなどのボールを、弾性ネット部材１０に対し、上方から突くと、弾性ネット部材１０が下方に伸張した後、その復元力でボールが上方に跳ね返される。これを連続的に行うことで、バスケットボールのドリブルや毬つきなどを行うことができる。Next, the operation of the embodiment will be described.
(while using it)
The ball game training tool A is used in a state where the bottom surface 33a of the cover member 33 of the leg member 30 is in contact with the floor, the ground, etc., and the support frame 20 and the elastic net member 10 are floated from the floor, the ground, etc.
In this state, when a ball such as a basketball (not shown) strikes the elastic net member 10 from above, the elastic net member 10 extends downward, and then the ball is rebounded upward by its restoring force. By doing this continuously, it is possible to perform basketball dribbling, mochi, and the like.

このとき、ボールは、地面や床に衝突して自身の弾性力により弾むのではなく、地面や床に衝突することなく弾性ネット部材１０の弾性力により弾むため、ボールを直接床や地面などにつく場合と比較して、ボールが跳ね返る際の音や振動の発生が抑制される。すなわち、ボールを突くときに発生する音や振動は、ボールが床や地面に衝突するのに伴って発生するとともに、ボール自身の弾性変形に伴う内部閉空間の圧力変化や共鳴により発生すると考えられる。 At this time, the ball does not collide with the ground or the floor and bounces with its own elastic force, but with the elastic force of the elastic net member 10 without colliding with the ground or the floor, the ball is directly applied to the floor or the ground. Compared to the case, generation of sound and vibration when the ball rebounds is suppressed. That is, it is considered that the sound and vibration generated when the ball is struck are generated as the ball collides with the floor or the ground, and also due to pressure change or resonance in the internal closed space due to elastic deformation of the ball itself.

それに対し、本実施の形態１の場合、ボールが衝突する相手は弾性ネット部材１０であり、地面や床と衝突するのと比較して、衝突音が小さく、また、弾性ネット部材１０は、大気中に開放されており、弾性変形および復元した際に、ボールのような閉空間での共鳴は生じることはなく、弾性ネット部材１０の伸縮変形に伴い発生される音や振動は極めて小さくなる。 On the other hand, in the case of the first embodiment, the opponent with which the ball collides is the elastic net member 10, and the collision sound is lower than that of the collision with the ground or the floor, and the elastic net member 10 When the elastic net member 10 is opened and elastically deformed and restored, resonance in a closed space such as a ball does not occur, and the sound and vibration generated with the expansion and contraction of the elastic net member 10 become extremely small.

さらに、弾性ネット部材１０は、網状を成しているため、弾性シートなどのシート状のものに衝突させる場合と比較して、ボールとの衝突音を抑えることができる。すなわち、ボールが弾性ネット部材１０に衝突した際の衝撃は、支持枠２０から床などに伝達され、その振動が衝突音を発生させる。この際、ボールとの衝突箇所から、支持枠２０への振動の伝達経路が、弾性シートの場合、直線的に伝達されるのに対し、弾性ネット部材１０では、網形状であることから、振動の伝達経路が何度も折れ曲がる経路となる。したがって、振動の伝達中の減衰量が多くなり、支持枠２０への振動伝達を抑え、結果、音、振動の発生を抑えることができる。 Furthermore, since the elastic net member 10 has a net shape, it is possible to suppress a collision sound with the ball as compared with a case where the elastic net member 10 collides with a sheet-like material such as an elastic sheet. That is, an impact when the ball collides with the elastic net member 10 is transmitted from the support frame 20 to the floor or the like, and the vibration generates a collision sound. At this time, the vibration transmission path from the collision point with the ball to the support frame 20 is linearly transmitted in the case of an elastic sheet, whereas the elastic net member 10 has a net shape, The transmission path is bent several times. Therefore, the amount of attenuation during the transmission of vibration increases, so that vibration transmission to the support frame 20 can be suppressed, and as a result, generation of sound and vibration can be suppressed.

また、弾性ネット部材１０は、網状に形成しているため、全体質量を抑えることができる。これにより、弾性ネット部材１０が、伸長して縮む際に支持枠２０に伝達されるエネルギーを抑え、このエネルギーにより支持枠２０が上下方向に移動するのを抑えることができ、支持枠２０がガタついて騒音が発生するのも抑えることができる。 Moreover, since the elastic net member 10 is formed in a net shape, the entire mass can be suppressed. As a result, the energy transmitted to the support frame 20 when the elastic net member 10 expands and contracts can be suppressed, and the support frame 20 can be prevented from moving up and down by this energy. In addition, noise can be suppressed.

加えて、脚部材３０の下端に発泡弾性材により形成されたカバー材３３を装着しているため、ボールを突いたときの入力が、脚部材３０を介して床や地面に伝達されることによる音、振動の発生を抑制できる。しかも、カバー材３３は、錐形状として底面３３ａの面積を広く確保しているため、この面積が狭いものよりもさらに、音、振動の発生を抑制できる。 In addition, since the cover member 33 formed of a foamed elastic material is attached to the lower end of the leg member 30, the sound generated when the input when the ball is struck is transmitted to the floor or the ground via the leg member 30. The occurrence of vibration can be suppressed. In addition, since the cover material 33 has a conical shape and a large area of the bottom surface 33a, the generation of sound and vibration can be further suppressed than those with a small area.

（ゴム疲労時）
経時的な使用により、弾性ネット部材１０の反発力が低下した場合、上述したように、支持枠２０の下面のストッパ部２２に係止する連結用ライン部１２の係止突起部１２ｂを、変更して弾性ネット部材１０の張力を強めることができる。(During rubber fatigue)
When the repulsive force of the elastic net member 10 is reduced due to use over time, the locking projection 12b of the connecting line portion 12 that locks to the stopper 22 on the lower surface of the support frame 20 is changed as described above. Thus, the tension of the elastic net member 10 can be increased.

あるいは、新しい弾性ネット部材１０と交換することも可能である。この場合、古い弾性ネット部材１０の連結用ライン部１２と支持枠２０との係合を外して弾性ネット部材１０を取り外し、新たな弾性ネット部材１０の連結用ライン部１２を、支持枠２０の縦溝２１に挿入して係止状態とすることで、交換することができる。 Alternatively, it can be replaced with a new elastic net member 10. In this case, the connection between the connection line portion 12 of the old elastic net member 10 and the support frame 20 is released, the elastic net member 10 is removed, and the connection line portion 12 of the new elastic net member 10 is connected to the support frame 20. It can be exchanged by inserting it into the longitudinal groove 21 to be in a locked state.

（実施の形態１の効果）
以上説明したように、実施の形態１の球技練習具Ａは、弾性素材により網状に形成された弾性ネット部材１０と、この弾性ネット部材１０を所定の張力で張った状態で弾性ネット部材１０の外周端縁部を支持する支持枠２０と、この支持枠２０に結合され、支持枠２０を所定の高さで略水平に保持する脚部材３０と、を備え、
前記弾性ネット部材１０が、上方から落ちてきた設定範囲の重さのボールを、前記伸縮による復元力で上方に跳ね返し可能な弾性力に設定されていることを特徴とする。
したがって、球技練習具の弾性ネット部材１０に連続的にボールをついてドリブルの練習や毬つきなどを行うことができるとともに、その際に、音、振動の発生を抑えることができる。しかも、弾性を有した網状の弾性ネット部材１０を用いたことにより、弾性シートを用いて場合と比較して、弾性ボールを突いた際の音、振動の発生をさらに抑えることが可能となった。(Effect of Embodiment 1)
As described above, the ball game training tool A according to Embodiment 1 includes the elastic net member 10 formed in a net shape by an elastic material, and the elastic net member 10 in a state where the elastic net member 10 is stretched with a predetermined tension. A support frame 20 that supports the outer peripheral edge, and a leg member 30 that is coupled to the support frame 20 and holds the support frame 20 substantially horizontally at a predetermined height;

Accordingly, it is possible to perform dribbling practice and tacking by continuously attaching the ball to the elastic net member 10 of the ball game practice tool, and at the same time, it is possible to suppress the generation of sound and vibration. In addition, the use of the elastic net-like elastic net member 10 makes it possible to further suppress the generation of sound and vibration when the elastic ball is struck, as compared to the case using an elastic sheet. .

また、実施の形態１の球技練習具Ａは、弾性ネット部材１０は、網状に形成された本体部１１と、この本体部１１から外方に延びる紐状に形成された連結用ライン部１２と、を備え、連結用ライン部１２が、本体部１１に張力を与えた状態で支持枠２０に係止されていることを特徴とする。
このように、連結用ライン部１２から弾性素材により網状に形成された本体部１１に直接張力を与え、本体部１１が弾性力を有するようにしたため、従来のトランポリンのように、別途、弾性力を有しないシートの外周に弾性力を有するコイルスプリングなどを追加設定する必要が無く、構造の簡略化を図り、コストダウンを達成可能である。
しかも、実施の形態１では、連結用ライン部１２は、本体部１１と一体に形成したものを用いたため、本体部１１とは別体の連結用紐状部を設けるものと比較して、部品点数を削減して、コストダウンを図ることができる。In the ball game training tool A according to the first embodiment, the elastic net member 10 includes a main body portion 11 formed in a net shape, and a connecting line portion 12 formed in a string shape extending outward from the main body portion 11. The connecting line portion 12 is locked to the support frame 20 in a state where tension is applied to the main body portion 11.
As described above, since the tension is directly applied to the main body 11 formed in a net shape by the elastic material from the connecting line portion 12 so that the main body 11 has an elastic force, the elastic force is separately provided like a conventional trampoline. There is no need to additionally set a coil spring or the like having elastic force on the outer periphery of the sheet that does not have, so that the structure can be simplified and the cost can be reduced.
In addition, in the first embodiment, since the connecting line portion 12 is formed integrally with the main body portion 11, the connecting line portion 12 is a component compared to a case in which a connecting string-like portion separate from the main body portion 11 is provided. Costs can be reduced by reducing the number of points.

さらに、実施の形態１の球技練習具Ａは、連結用ライン部１２は、その延在方向に支持枠２０に係止可能な係止突起部１２ｂを複数備え、支持枠２０に係止する係止突起部１２ｂの位置の違いにより、本体部１１の弾性力を変更可能に形成されていることを特徴とする。
このように、本体部１１の弾性力を変更可能であるため、使用者の好みに応じてボールを突いた時の跳ね返り具合を任意に調整可能であり、使い勝手に優れる。しかも、この張力の調整を、連結用ライン部１２に単に係止突起部１２ｂを複数設けることにより達成できるため、上記弾性力の調整を安価に達成可能である。Furthermore, in the ball game training tool A of the first embodiment, the connecting line portion 12 includes a plurality of locking projections 12b that can be locked to the support frame 20 in the extending direction, and the locking line portion 12 is locked to the support frame 20. The elastic force of the main body 11 can be changed depending on the position of the stop protrusion 12b.
Thus, since the elastic force of the main-body part 11 can be changed, it is possible to arbitrarily adjust the rebound state when the ball is struck according to the user's preference, and it is excellent in usability. In addition, the adjustment of the tension can be achieved by simply providing a plurality of the locking projections 12b on the connecting line portion 12, so that the adjustment of the elastic force can be achieved at a low cost.

加えて、実施の形態１の球技練習具Ａは、弾性ネット部材１０は、ハニカム状に形成されていることを特徴とする。
これにより、弾性ネット部材１０の強度を確保可能であり、これを安価に達成することができる。In addition, the ball game training tool A of Embodiment 1 is characterized in that the elastic net member 10 is formed in a honeycomb shape.
Thereby, the intensity | strength of the elastic net member 10 is securable, and this can be achieved at low cost.

さらに、実施の形態１の球技練習具Ａは、ハニカム状の本体部１１の外周に、ハニカム同士をハニカムの１／２の形状の部分で連結した第１の連結部１１ａと、ハニカムの１つの角部を省略した５角形状として連結した第２の連結部１１ｂとを、周方向に交互に配置し、各連結部１１ａ，１１ｂの周方向中央に、連結用ライン部１２を一体に形成したことを特徴とする。
したがって、弾性ネット部材１０の本体部１１をハニカム形状の網状に形成したものにおいて、連結用ライン部１２を放射状に外径方向に延ばすのにあたり、ハニカム同士の間の位置から本体部１１の強度を確保しつつ、連結用ライン部１２を外径方向に延在させることができる。Furthermore, the ball training equipment A according to the first embodiment includes a first connecting portion 11a in which the honeycombs are connected to each other at the outer periphery of the honeycomb-shaped main body portion 11 by a half-shaped portion of the honeycomb, and one honeycomb. The second connecting portions 11b connected as a pentagon shape with the corner portions omitted are alternately arranged in the circumferential direction, and the connecting line portion 12 is integrally formed at the center in the circumferential direction of each connecting portion 11a, 11b. It is characterized by that.
Therefore, in the case where the main body portion 11 of the elastic net member 10 is formed in a honeycomb-like net shape, the strength of the main body portion 11 is increased from the position between the honeycombs when the connecting line portions 12 are radially extended in the outer diameter direction. The connecting line portion 12 can be extended in the outer diameter direction while ensuring.

また、実施の形態１の球技練習具Ａは、支持枠２０は、円環状に形成され、かつ、周方向に複数に分割された分割枠２０ａ，２０ｂ，２０ｃを結合して形成されていることを特徴とする。
このように、支持枠２０を円環状に形成することにより、三角形状や四角形状などの角数の少ない多角形状に形成した場合と比較して、弾性ネット部材１０の張力の均一化を図り、跳ね返り性の安定化を図ることができる。
しかも、複数に分割された分割枠２０ａ，２０ｂ，２０ｃを結合して支持枠２０を形成したことにより、一体に形成したものよりも製造時の歩留まりを向上することができる。Further, in the ball game training tool A of the first embodiment, the support frame 20 is formed in an annular shape, and is formed by joining divided frames 20a, 20b, and 20c divided into a plurality in the circumferential direction. It is characterized by.
Thus, by forming the support frame 20 in an annular shape, the tension of the elastic net member 10 is made uniform compared to the case where the support frame 20 is formed in a polygonal shape with a small number of angles such as a triangular shape or a quadrangular shape, It is possible to stabilize the rebound characteristics.
In addition, since the support frames 20 are formed by joining the divided frames 20a, 20b, and 20c divided into a plurality of parts, it is possible to improve the manufacturing yield as compared with the case where the support frames 20 are integrally formed.

そして、実施の形態１の球技練習具Ａは、脚部材３０のブラケット部３１は、複数に分割された分割枠２０ａ，２０ｂ，２０ｃ同士を結合する部材を兼ねることを特徴とする。
したがって、分割枠２０ａ，２０ｂ，２０ｃ同士を結合するための単独の部材を追加設定するものと比較して、部品点数を削減してコストダウンを図ることができる。And the ball game training tool A of Embodiment 1 is characterized in that the bracket portion 31 of the leg member 30 also serves as a member that joins the divided frames 20a, 20b, and 20c divided into a plurality.
Therefore, the number of parts can be reduced and the cost can be reduced as compared with a case where a single member for connecting the divided frames 20a, 20b, and 20c is additionally set.

また、脚部材３０は、下端部の外周に発泡材製のカバー材３３が装着されていることを特徴とする。
したがって、ボールを突いた時の振動が、支持枠２０から脚部材３０を介して、実施の形態の球技練習具Ａを載置する床面などに伝達されるのをさらに抑え、音、振動の発生をさらに抑制することができる。
しかも、カバー材３３は、錐形状として底面３３ａを、その上方部分よりも広い面積を確保したため、上記の音、振動の抑制効果をさらに高めることができる。Further, the leg member 30 is characterized in that a foam cover material 33 is mounted on the outer periphery of the lower end portion.
Therefore, the vibration when the ball is struck is further suppressed from being transmitted from the support frame 20 through the leg member 30 to the floor surface on which the ball game training tool A of the embodiment is placed, and the sound and vibration are suppressed. Occurrence can be further suppressed.
In addition, since the cover member 33 has a conical shape and the bottom 33a has a larger area than its upper portion, the effect of suppressing the sound and vibration can be further enhanced.

次に、図５にその要部を示す実施の形態２の球技練習具について説明する。
この実施の形態２の球技練習具は、支持枠２００および脚部材２３０の構成が実施の形態１と異なる。
実施の形態２では、支持枠２００を複数に分割（例えば、実施の形態１と同様に三分割）した分割枠２０２ａ，２０２ｂ（三分割した２つのもののみを図示）は、それぞれ、周方向の両端部に、脚部２３１，２３２を一体に備える。(Other embodiments)
Next, a ball practice tool of another embodiment will be described.
In the description of the other embodiments, the same reference numerals are given to the same components as those already described, and the description will be omitted, and only the differences will be described.

Next, the ball game training tool of Embodiment 2 which shows the principal part in FIG. 5 is demonstrated.
The ball game training tool of the second embodiment is different from the first embodiment in the configuration of the support frame 200 and the leg member 230.
In the second embodiment, the divided frames 202a and 202b (only two of the three divided frames are shown) obtained by dividing the support frame 200 into a plurality of parts (for example, three parts in the same manner as in the first embodiment) are respectively provided in the circumferential direction. Leg portions 231 and 232 are integrally provided at both ends.

そして、各分割枠２０２ａ，２０２ｂを、周方向に連続して配置した状態で、対向して配置される各脚部２３１，２３２を、図示を省略したボルト・ナットやビスなどの締結具や接着剤や溶接などにより、一体に結合させることにより、脚部材２３０が形成されている。また、上記の各脚部２３１，２３２を結合させることにより、分割枠２０２ａ，２０２ｂが周状に連続して配置され、実施の形態１と同様に、円環状を成す支持枠２００が形成される。 Then, with the divided frames 202a and 202b continuously arranged in the circumferential direction, the leg portions 231 and 232 that are arranged to face each other are fastened with fasteners such as bolts, nuts, screws, and the like that are not shown. The leg member 230 is formed by integrally bonding with an agent or welding. Further, by combining the above leg portions 231 and 232, the divided frames 202a and 202b are continuously arranged in a circumferential shape, and the support frame 200 having an annular shape is formed as in the first embodiment. .

なお、上述の脚部材２３０の下端部には、実施の形態１と同様に、カバー材２３３が装着されている。また、上述のような脚部２３１，２３２が一体に形成された各分割枠２０２ａ、２０２ｂは、ステンレスなどの金属板により形成されているものとするが、樹脂など他の素材により形成することもできる。 Note that a cover member 233 is attached to the lower end portion of the leg member 230 as in the first embodiment. Each of the divided frames 202a and 202b in which the leg portions 231 and 232 are integrally formed as described above is formed of a metal plate such as stainless steel, but may be formed of other materials such as resin. it can.

以上のように、実施の形態２の球技練習具は、支持枠２００が、複数の分割枠２０２ａ，２０２ｂから形成され、各分割枠２０２ａ，２０２ｂは、周方向の両端に脚部２３１，２３２が一体に形成され、複数の分割枠２０２ａ，２０２ｂを、周方向に連続して配置し、隣り合う脚部２３１，２３２同士を結合して、支持枠２００および脚部材２３０が形成されていることを特徴とする。 As described above, in the ball game practice tool according to the second embodiment, the support frame 200 is formed of the plurality of divided frames 202a and 202b, and each of the divided frames 202a and 202b has the leg portions 231 and 232 at both ends in the circumferential direction. The support frame 200 and the leg member 230 are formed by integrally forming a plurality of divided frames 202a and 202b continuously arranged in the circumferential direction and connecting the adjacent leg portions 231 and 232 to each other. Features.

したがって、独立した脚部材が不要になり、部品点数を削減し製造のコストおよび手間を削減できる。
また、分割枠２０２ａ，２０２ｂおよびそれと一体の脚部２３１，２３２を金属により形成したため、支持枠２００の重量が確保でき、ボール突きを行った際に、弾性ネット部材１０の伸縮に伴って、支持枠２００が移動するのを抑制できる。これにより、音、振動の発生を、いっそう低減可能である。
なお、本実施の形態２の球技練習具においては、実施の形態１と同様に支持枠２００の外周部には、円周方向に等間隔で１２箇所に、支持枠２００の円弧の中心軸に沿う方向に延在された縦溝２２１が形成されている。この縦溝２２１は、溝幅が、ライン部本体１２ａの直径寸法程度であって係止突起部１２ｂより幅狭に形成されているとともに、外径側の開口部分が、ライン部本体１２ａの直径よりも幅を狭く形成されている。そして、縦溝２２１の下端部の外周縁部の支持枠２００の下端面が、係止突起部１２ｂを前記中心軸に沿う方向に係止させることができるストッパ部とされている。Therefore, an independent leg member is not required, and the number of parts can be reduced, and the manufacturing cost and labor can be reduced.
In addition, since the divided frames 202a and 202b and the leg portions 231 and 232 integrated therewith are formed of metal, the weight of the support frame 200 can be secured, and when the ball is hit, the elastic net member 10 is expanded and contracted. The movement of the frame 200 can be suppressed. Thereby, generation | occurrence | production of a sound and a vibration can be reduced further.
In the ball game practice tool of the second embodiment, as in the first embodiment, the outer periphery of the support frame 200 is arranged at twelve positions at equal intervals in the circumferential direction and the central axis of the arc of the support frame 200. A longitudinal groove 221 extending in the direction along the line is formed. The vertical groove 221 has a groove width that is about the diameter of the line main body 12a and is narrower than the locking projection 12b, and an opening on the outer diameter side has a diameter of the line main body 12a. The width is narrower than that. And the lower end surface of the support frame 200 of the outer peripheral edge part of the lower end part of the vertical groove 221 is made into the stopper part which can latch the latching protrusion part 12b in the direction along the said central axis.
