Description

本発明は、ボールのコントロールを向上させる球技練習用具に関するものである。 The present invention relates to a ball game practice tool that improves ball control.

従来より、ボールのコントロールを向上させる球技練習用具として、打球の飛行線側に補給網袋を装着して打球方向に対向する大口径リングを移動可能な基台に架設したテニス練習用補球集器が知られている（例えば、特許文献１）。このテニス練習補給集器によれば、ボールの飛行コントロールの練習ができるとされる。 Conventionally, as a ball game practice tool to improve the control of the ball, a supplementary ball collection for tennis practice in which a supply net bag is attached to the flight line side of the hit ball and a large diameter ring facing the hit ball direction is mounted on a movable base A container is known (for example, Patent Document 1). According to this tennis practice supply collector, it is said that the flight control of the ball can be practiced.

実用新案登録第３０３２５０２号公報Utility Model Registration No. 3032502

しかしながら、このテニス練習用補球集器には、大口径リングに補球網袋が取り付けられているため、大口径リング内を通過したボールは補球網袋に収納され、その収納されたボールの重みで補給網袋が大口径リングを塞いでしまうので、連続して大口径リング内にボールを打ち込むことができなかった。 However, in this tennis practice compensator, a prosthetic mesh bag is attached to the large-diameter ring, so that the ball that has passed through the large-diameter ring is stored in the prosthetic net bag, and the stored ball Since the replenishment net bag blocked the large-diameter ring with the weight of, the ball could not be continuously driven into the large-diameter ring.

また、大口径リング内に打ち込まれたボールは、補給網袋内に収納されるので、打ち込まれたボールの着地点を確認することができないものであった。 In addition, since the ball driven into the large-diameter ring is stored in the supply net bag, it is impossible to confirm the landing point of the driven ball.

例えば、テニスのようにボールの着地点が非常に重要となる球技の場合、上述したような練習用具では、ボールの飛行コントロールの練習にはなったとしても、着地点を確認することができないため効果的な練習が出来なかった。 For example, in the case of a ball game in which the landing point of the ball is very important, such as tennis, it is not possible to confirm the landing point with the above-described training equipment even if the ball flight control is practiced. I could not practice effectively.

本発明は、上記課題に鑑みてなされたものであって、その目的とするところは、好ましい通過点にボールを打ち込む練習ができると共に、ボールの着地点を確認することができる球技練習用具を提供することにある。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a ball game training tool that can practice hitting a ball at a preferred passing point and can check the landing point of the ball.

以下、本発明に係る実施形態を図面に従って説明するが、本発明はこの実施形態に限定されるものではない。 Hereinafter, embodiments according to the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments.

〔第１実施形態について〕
図１は、本発明の第１実施形態に係る球技練習用具の正面図である。図２は、図１の一部拡大平面図である。なお、本明細書において、図２に示すように、ボールを打ち込む側を前側とし、枠体１に対してその反対側を後側とする。また、支持台２の長手方向を左右方向とする。 [About the first embodiment]
FIG. 1 is a front view of a ball game training tool according to a first embodiment of the present invention. FIG. 2 is a partially enlarged plan view of FIG. In this specification, as shown in FIG. 2, the side into which the ball is hit is the front side, and the opposite side of the frame 1 is the rear side. Moreover, let the longitudinal direction of the support stand 2 be the left-right direction.

この球技練習用具は、ボールを通過させる中空部１１が形成された枠体１を備える。枠体１は支持台２上に配されている。支持台２には、枠体１を支持するための支持部３と、枠体１を挟持する右側ホルダーＨＲと左側ホルダーＨＬとが備えられている。支持台２は、鉛直方向に立設させた支柱６の上部に設けられている。支柱６は基台７に連結されることにより鉛直方向に起立している。 This ball game training tool includes a frame 1 in which a hollow portion 11 through which a ball passes is formed. The frame 1 is disposed on the support base 2. The support base 2 includes a support portion 3 for supporting the frame body 1, a right holder HR and a left holder HL that sandwich the frame body 1. The support base 2 is provided on an upper portion of the support column 6 that is erected in the vertical direction. The support column 6 is erected in the vertical direction by being connected to the base 7.

図１に示すように、枠体１は、ボールが通過可能な中空部１１が形成された環状体である。つまり、中空部１１の形状が円であるが、これに限定されるものではなく、練習に使用されるボールが通過可能な中空部１１が形成されていれば良く、例えば、正方形、長方形、三角形、楕円形、多角形状等の中空部１１を有する枠体１でも構わない。この実施の形態では、枠体１は樹脂で形成されているが、これに限定されるものではなく、例えば金属等で形成されていてもよい。 As shown in FIG. 1, the frame 1 is an annular body in which a hollow portion 11 through which a ball can pass is formed. That is, the shape of the hollow portion 11 is a circle, but the shape is not limited to this, and it is only necessary to form the hollow portion 11 through which a ball used for practice can pass. For example, a square, a rectangle, a triangle Alternatively, the frame body 1 having the hollow portion 11 such as an elliptical shape or a polygonal shape may be used. In this embodiment, the frame 1 is made of resin, but is not limited to this, and may be made of, for example, metal.

この実施の形態の枠体１は、コストの低減や軽量化等を考慮し、市販されているフラフープを使用している。なお、フラフープの中空部１１は、特にテニスの練習用具として好ましい形状と大きさを有しているため、本発明の球技練習用具が、テニスの球技練習用具として用いられる場合に好ましい枠体１である。 The frame 1 of this embodiment uses a commercially available hula hoop in consideration of cost reduction and weight reduction. The hollow portion 11 of the hula hoop has a shape and size that are particularly preferable as a tennis training tool. Therefore, when the ball game training tool of the present invention is used as a tennis ball training tool, the frame 1 is preferable. is there.

なお、枠体１は、球技に使用されるボールの大きさ、練習の目的、練習の難易度等によって中空部１１の大きさ、形状が異なる枠体１に適宜変更することができる。 The frame 1 can be appropriately changed to the frame 1 having a different size and shape of the hollow portion 11 depending on the size of the ball used in the ball game, the purpose of the practice, the difficulty of the practice, and the like.

図１及び図２に示すように、支持台２は板体である。具体的には、支持台２は角丸略長方形の薄板体である。支持台２の上面略中央には、支持部３が設けられている。支持台２の長手方向両端近傍には、それぞれホルダー取付孔２１が設けられている。支持台２の下面略中央には支柱６を取り付けるための接続部２２が設けられている。支持台２の大きさは、支持部１１と左右のホルダー取り付け孔２１が設けられ、かつ、支持台２に枠体１を配したときに安定して起立できる適宜の大きさの板体であればよい。なお、接続部２２の位置は、支持台２の下面の略中央に限られず、球技練習用具が安定して起立可能であれば特に限定されない。 As shown in FIGS. 1 and 2, the support base 2 is a plate. Specifically, the support base 2 is a thin plate body having a substantially rectangular shape with rounded corners. A support portion 3 is provided substantially at the center of the upper surface of the support base 2. Holder attachment holes 21 are provided in the vicinity of both ends in the longitudinal direction of the support base 2. A connection portion 22 for attaching the support column 6 is provided at substantially the center of the lower surface of the support base 2. The size of the support 2 is a plate having an appropriate size that is provided with the support 11 and the left and right holder mounting holes 21 and that can stand up stably when the frame 1 is arranged on the support 2. That's fine. In addition, the position of the connection part 22 is not restricted to the approximate center of the lower surface of the support stand 2, and will not be specifically limited if the ball game training tool can stand up stably.

図３（ａ）は、支持台２にホルダーＨを取り付けた状態の拡大平面図であり、図３（ｂ）は図３（ａ）のＣ−Ｃ線断面図であり、図３（ｃ）は図３（ａ）のＤ−Ｄ線断面図である。これらの図に示すように、支持部３は、支持台２の略中央に２枚の板体が長手方向に沿って立設されている。したがって２枚の板体が平行に配置されている。その２枚の板体の間隙、つまり向かい合う支持部３の間隙の長さ（以下、「支持部間長さＬ１」という。）は、図４に示すように、支持台２に載置された状態の枠体１の前後方向断面の前後方向長さ（以下、「枠体前後長さＬ２」という。）と同一、又は、支持部間長さＬ１は枠体前後長さＬ２より僅かに長い。すなわち、枠体１がフラフープの場合、支持部間長さＬ１は、フラフープの円周枠体１の断面直径と同一又は僅かに長く形成されている。 3A is an enlarged plan view of a state in which the holder H is attached to the support base 2, and FIG. 3B is a cross-sectional view taken along the line CC of FIG. 3A, and FIG. FIG. 4 is a cross-sectional view taken along line DD of FIG. As shown in these drawings, the support portion 3 has two plate bodies erected along the longitudinal direction substantially at the center of the support base 2. Therefore, the two plates are arranged in parallel. The gap between the two plates, that is, the length of the gap between the support portions 3 facing each other (hereinafter referred to as “length L1 between the support portions”) was placed on the support base 2 as shown in FIG. It is the same as the length in the front-rear direction of the cross-section in the front-rear direction of the frame body 1 (hereinafter referred to as “frame body front-rear length L2”), or the inter-support length L1 is slightly longer than the frame front-rear length L2. . That is, when the frame body 1 is a hula hoop, the length L1 between the support portions is formed to be the same as or slightly longer than the cross-sectional diameter of the circumferential frame body 1 of the hula hoop.

なお、支持部３は前記構成に限られず、枠体１の少なくとも前後方向の動きを規制できればどのような構成でもよい。例えば、図５（ａ）に示すように、平行に向かい合う板体の底部を結ぶ底板３２を有する断面略コの字状部材を支持台２上に取り付けて支持部３としてもよい。また、図５（ｂ）に示すように、支持部３の長手方向に直線的に並べて配置された複数のピンと、その複数のピンに対して略平行となるように、直線状に並べて配置された複数のピンを支持部３としてもよい。 In addition, the support part 3 is not restricted to the said structure, What kind of structure may be sufficient if the movement of the frame 1 at least in the front-back direction can be controlled. For example, as shown in FIG. 5 (a), a substantially U-shaped member having a bottom plate 32 that connects the bottom portions of the plate members facing each other in parallel may be attached on the support base 2 to form the support portion 3. Further, as shown in FIG. 5B, a plurality of pins arranged linearly in the longitudinal direction of the support portion 3 and arranged in a straight line so as to be substantially parallel to the plurality of pins. A plurality of pins may be used as the support portion 3.

さらに、図５（ｃ）に示すように、断面略逆Ｕ字状のカバー部３６の端縁に板体３７を有する支持部３としてもよい。支持部のカバー部３６は、支持台２に載置された枠体１を覆う形状である。板体３７には、支持台２と接続するための接続部材３４が貫通するねじ孔３３が設けられている。このような支持部３であれば、枠体１の前後方向の動きを規制するだけでなく、上下方向の動きも規制できる。また、Ｕ字状のカバー部３６の断面形状を枠体１の断面形状と略対応する形状とし、枠体１と支持部３との接触面積を増やせば、枠体１を支持台２により固定した状態で支持することができる。 Furthermore, as shown in FIG. 5C, the support portion 3 may have a plate body 37 at the end edge of the cover portion 36 having a substantially inverted U-shaped cross section. The cover portion 36 of the support portion has a shape that covers the frame body 1 placed on the support base 2. The plate body 37 is provided with a screw hole 33 through which a connection member 34 for connecting to the support base 2 passes. With such a support portion 3, not only the movement of the frame body 1 in the front-rear direction but also the movement in the vertical direction can be restricted. In addition, if the cross-sectional shape of the U-shaped cover portion 36 is substantially the same as the cross-sectional shape of the frame body 1 and the contact area between the frame body 1 and the support portion 3 is increased, the frame body 1 is fixed by the support base 2. Can be supported.

図３（ａ）及び（ｂ）に示すように、ホルダー取付孔２１は、支持台２の両端近傍にそれぞれ形成されている。このホルダー取付孔２１は、ホルダーＨを支持台２に着脱自在に立設させるものである。この実施形態では、ホルダー取付孔２１は、略長方形状の貫通孔とされている。しかし、ホルダー取付孔２１は、ホルダーＨを着脱自在に立設できればよく、ホルダー取付孔２１の形状は特に限定されるものではない。 As shown in FIGS. 3A and 3B, the holder mounting holes 21 are formed in the vicinity of both ends of the support base 2. The holder mounting hole 21 allows the holder H to be detachably installed on the support base 2. In this embodiment, the holder mounting hole 21 is a substantially rectangular through hole. However, the holder mounting hole 21 only needs to be able to detachably mount the holder H, and the shape of the holder mounting hole 21 is not particularly limited.

図６に示すように、ホルダーＨは枠体１を挟持するものである。ホルダーＨは、支点部Ｈ２を介して第１挟持部４１と第１持ち手部４２とを有する第１部材４と、支点部Ｈ２を介して第２挟持部５１と第２持ち手部５２とを有する第２部材５とを備えている。ホルダーＨは、弾性部材によって、第１持ち手部４２と第２持ち手部５２とを内側方向に押圧し近接させることにより、第１挟持部４１と第２挟持部５１とが開き、第１持ち手部４２と第２持ち手部５２とを押圧しない状態では、第１持ち手部４２と第２持ち手部５２とが開き、第１挟持部４１と第２挟持部５１とが閉じる構造のものである。 As shown in FIG. 6, the holder H holds the frame body 1. The holder H includes a first member 4 having a first clamping part 41 and a first handle part 42 via a fulcrum part H2, and a second clamping part 51 and a second handle part 52 via a fulcrum part H2. The 2nd member 5 which has these. In the holder H, the first holding part 41 and the second holding part 51 are opened by pressing the first holding part 42 and the second holding part 52 inward by the elastic member, and the first holding part 41 and the second holding part 51 are opened. In a state where the handle portion 42 and the second handle portion 52 are not pressed, the first handle portion 42 and the second handle portion 52 are opened, and the first sandwiching portion 41 and the second sandwiching portion 51 are closed. belongs to.

また、第１挟持部４１と第２挟持部５１とは、互いに湾曲形状をしている。したがって、第１持ち手部４２と第２持ち手部５２とを押圧していない状態において、向い合う第１挟持部４１と第２挟持部５１の先端部Ｈ３どうしが当接し貫通孔Ｈ１が形成されている。第１挟持部４１と第２挟持部５１とはそれぞれ内側に向けて複数の突起５３が設けられている。第１持ち手部４２の外縁５４と第２持ち手部５２の外縁５４を結ぶ長さは、支点部Ｈ２から離れるに従って長くなっている。 Moreover, the 1st clamping part 41 and the 2nd clamping part 51 have mutually curved shape. Therefore, in a state where the first handle portion 42 and the second handle portion 52 are not pressed, the front end portions H3 of the first holding portion 41 and the second holding portion 51 facing each other come into contact with each other to form the through hole H1. Has been. Each of the first clamping part 41 and the second clamping part 51 is provided with a plurality of protrusions 53 facing inward. The length connecting the outer edge 54 of the first handle portion 42 and the outer edge 54 of the second handle portion 52 becomes longer as the distance from the fulcrum portion H2 increases.

図６に示すように、ホルダーＨを支持台２のホルダー取付孔２１に取り付けた状態において、ホルダーＨが支持台２と当接する箇所における第１部材４の外縁５４から第２部材５の外縁５４の長さ（以下、「固定部外縁長さＬ３」という。）は、ホルダー取付孔２１における、ホルダーＨの第１部材４の外縁５４と第２部材５の外縁５４が当接する方向の長さ、つまり、本実施の形態においては、ホルダー取付孔２１の長手方向の長さ（以下、「取付孔長さＬ４」という。）と略同じである。また、ホルダーＨが支持台２と当接する箇所よりも上方近傍の第１部材４の外縁５４から第２部材５の外縁５４の長さ（以下、「ホルダー外縁長さＬ５という。）は、取付孔長さＬ４よりも長い。さらに、ホルダーＨが支持台２と当接する箇所よりも下方近傍のホルダー外縁長さＬ５は、取付孔長さＬ４よりも長い。したがって、ホルダーＨは、上下方向の動きを規制され固定される。また、ホルダーＨが取り付けられる位置によっては、ホルダーＨに設けられた弾性部材の付勢力によっても支持台２に固定される。 As shown in FIG. 6, the outer edge 54 of the second member 5 is changed from the outer edge 54 of the first member 4 at a position where the holder H comes into contact with the support base 2 in a state where the holder H is mounted in the holder mounting hole 21 of the support base 2. Is the length in the direction in which the outer edge 54 of the first member 4 and the outer edge 54 of the second member 5 of the holder H are in contact with each other in the holder mounting hole 21. That is, in the present embodiment, it is substantially the same as the length of the holder mounting hole 21 in the longitudinal direction (hereinafter referred to as “mounting hole length L4”). Further, the length from the outer edge 54 of the first member 4 to the outer edge 54 of the second member 5 in the vicinity of the upper portion of the holder H in contact with the support base 2 (hereinafter referred to as “holder outer edge length L5”) is attached. It is longer than the hole length L4.Further, the holder outer edge length L5 in the vicinity below the portion where the holder H abuts the support base 2 is longer than the mounting hole length L4. The movement is restricted and fixed, and depending on the position where the holder H is attached, the holder H is also fixed by the urging force of the elastic member provided on the holder H.

さらに、図３（ａ）に示すように、ホルダー取付孔の短手方向長さＬ６を、ホルダーの幅Ｌ７と同一又は僅かに長く形成すれば、ホルダーＨの左右方向への動きを規制することができる。 Furthermore, as shown in FIG. 3A, if the length L6 in the short direction of the holder mounting hole is formed equal to or slightly longer than the width L7 of the holder, the movement of the holder H in the left-right direction is restricted. Can do.

図６に示すように、枠体１は、ホルダーＨの貫通孔Ｈ１部分に配置された状態にて挟持される。具体的には、枠体１は、第１挟持部４１と第２挟持部５１とに形成された突起５３に当接し挟持される。なお、突起５３を形成せずに、第１挟持部４１と第２挟持部５１の内側面にて枠体を挟持する構成とすることもできる。また、枠体１の径が大きい場合等、第１挟持部４１と第２挟持部５１の先端部Ｈ３が当接せず、第１挟持部４１と第２挟持部５１とが開いた状態にて挟持されることもある。 As shown in FIG. 6, the frame body 1 is sandwiched in a state where it is disposed in the through hole H1 portion of the holder H. Specifically, the frame body 1 is held in contact with the protrusions 53 formed on the first holding part 41 and the second holding part 51. Note that the frame body may be sandwiched between the inner surfaces of the first sandwiching portion 41 and the second sandwiching portion 51 without forming the protrusion 53. In addition, when the diameter of the frame 1 is large, the first clamping part 41 and the second clamping part 51 are not in contact with each other, and the first clamping part 41 and the second clamping part 51 are opened. May be pinched.

この実施の形態では、ホルダーＨは、洗濯物を留める洗濯バサミと同様の、スプリングの効果により被挟持物を挟持する構成の留め具を利用しており、洗濯バサミでいえば、竿を挟持する部分に枠体１を挟持させている。 In this embodiment, the holder H uses a fastener configured to hold the object to be clamped by the effect of the spring, similar to the clothespin for holding the laundry. In the case of the clothespin, the holder H holds the bag. The frame 1 is held between the portions.

以下に、球技練習用具の組み立て方法を説明する。 Below, the assembly method of a ball game training tool is demonstrated.

まず、基台７に設けられた取付部７１に支柱６を挿入し、支柱６を基台７に取り付ける。次いで、支柱６に支持台２の接続部２２を挿入し、支柱６と支持台２とを接続する。次いで、支持台２に設けられた左右のホルダー取付孔２１に、それぞれホルダーＨを取り付ける。具体的には、一方のホルダーＨの第１持ち手部４２と第２持ち手部５２とを内側に向けて押圧するように手で握る。そして、持ち手部側のホルダー外縁長さＬ５を取付孔長さＬ４よりも短くする。この状態のまま、挟持部４１，５１側を上側にして、ホルダーＨをホルダー取付孔２１の上方から下方に向けて挿入する。そして、ホルダーＨが適宜の位置に挿入されたところで、第１持ち手部４２と第２持ち手部５２から手を放して、ホルダーＨを支持台２に固定する。同様にして、もう一方のホルダーＨをホルダー取付孔２１に取り付ける。次いで、枠体１を支持台２に配する。具体的には、支持台２に取り付けられた状態の一方のホルダーＨの第１保持部と第２保持部を手で握り、第１挟持部４１と第２挟持部５１を開いて、貫通孔Ｈ１部分に枠体１を配置した後、手を離して第１挟持部４１と第２挟持部５１とを閉じて枠体１を挟持させる。次いで、枠体１を支持体の間隙に配置させる。最後に、もう一方のホルダーＨに、上記と同様にして枠体１を挟持させれば、支持台２上に枠体１が起立した状態で固定される。枠体１は、図１に示すように支持台２に当接していない状態で起立させることもできるし、支持台２に当接した状態で起立させることもできる。なお、上述した球技練習用具の組み立て方法の工程順は一例に過ぎず、球技練習用具が適切に組み上がれば、どのような組み立て工程順でも構わない。 First, the column 6 is inserted into the mounting portion 71 provided on the base 7, and the column 6 is attached to the base 7. Next, the connection portion 22 of the support base 2 is inserted into the support 6 to connect the support 6 and the support 2. Next, the holders H are respectively attached to the left and right holder attaching holes 21 provided in the support base 2. Specifically, the first handle portion 42 and the second handle portion 52 of one holder H are gripped by a hand so as to be pressed inward. And the holder outer edge length L5 by the side of a handle is made shorter than the attachment hole length L4. In this state, the holder H is inserted from the upper side to the lower side of the holder mounting hole 21 with the holding portions 41 and 51 side facing upward. Then, when the holder H is inserted at an appropriate position, the first handle portion 42 and the second handle portion 52 are released, and the holder H is fixed to the support base 2. Similarly, the other holder H is attached to the holder attachment hole 21. Next, the frame body 1 is arranged on the support base 2. Specifically, the first holding part and the second holding part of one of the holders H attached to the support base 2 are gripped by hand, the first holding part 41 and the second holding part 51 are opened, and the through hole After the frame body 1 is arranged in the H1 portion, the hand is released to close the first clamping part 41 and the second clamping part 51 to clamp the frame body 1. Next, the frame 1 is placed in the gap between the supports. Finally, if the frame 1 is sandwiched between the other holders H in the same manner as described above, the frame 1 is fixed on the support base 2 in an upright state. As shown in FIG. 1, the frame 1 can be erected in a state where it is not in contact with the support base 2, or can be erected in a state where it is in contact with the support base 2. In addition, the process order of the assembly method of the above-described ball game practice tool is only an example, and any assembly process order may be used as long as the ball game practice tool is appropriately assembled.

このようにして、支持台２上に配された枠体１は、支持部３と右側ホルダーＨＲと左側ホルダーＨＬとが、直線上に並んで配置されているため、図１に示すように支持台２の水平方向に対して垂直に起立する。具体的には、枠体１の中央下端部（中央下端部近傍を含むものとする）が支持部３と、右側ホルダーＨＲと、左側ホルダーＨＬとによって支持され起立する。さらに具体的には、枠体１の下方の円弧部が３点支持される。つまり、枠体１と支持台２との略接点部分Ｓが支持部３に支持され、その略接点部分Ｓからそれぞれ適宜離れた枠体１の円周上の一部が右側ホルダーＨＲと左側ホルダーＨＬとに挟持されている。なお、枠体１が、ホルダーＨによって挟持される箇所は、枠体１が支持台２上に安定した状態で起立可能であれば、その位置は特に限定されない。なお、枠体１を前後方向に回動させた状態で、ホルダーＨに挟持させることもできる。 In this manner, the frame body 1 arranged on the support base 2 is supported as shown in FIG. 1 because the support portion 3, the right holder HR, and the left holder HL are arranged side by side on a straight line. Stands vertically with respect to the horizontal direction of the table 2. Specifically, the central lower end portion (including the vicinity of the central lower end portion) of the frame body 1 is supported and stands by the support portion 3, the right holder HR, and the left holder HL. More specifically, the arc portion below the frame 1 is supported at three points. That is, a substantially contact portion S between the frame body 1 and the support base 2 is supported by the support portion 3, and a part of the circumference of the frame body 1 appropriately separated from the substantially contact portion S is a right holder HR and a left holder. It is sandwiched between HL. The position where the frame body 1 is held by the holder H is not particularly limited as long as the frame body 1 can stand up on the support base 2 in a stable state. In addition, the frame body 1 can also be clamped by the holder H in the state rotated in the front-back direction.

本実施形態に係る球技練習用具によれば、好ましい通過点にボールを打ち込む練習ができると共に、その打ち込んだボールの着地点を確認することが可能となるので、ボールにスピンがかかっているか否か又はスピンの掛かり具合を容易に知ることができる。したがって、特にテニスのような、ボールの着地点が重要となる球技の練習を効果的に行うことができる。具体的には、球技練習用具をコート内のネット際や、サービスライン、ベースライン近傍等練習の目的に合った適宜の位置に設置することで、種々の打ち方の練習を効果的に行うことができる。また、枠体１を少なくとも３点で支持しているので、枠体１が安定した状態で支持台２上に固定することが可能となる。また、この球技用練習用具は、枠体１、支持台２、ホルダーＨ、支柱６及び基台７の各部品を用いて簡易に組み立てることができると共に、簡易に分解可能である。したがって、コンパクトに収納でき、運搬も容易となる。 According to the ball game practice tool according to the present embodiment, it is possible to practice hitting the ball at a preferred passing point and to check the landing point of the hit ball, so whether or not the ball is spun. Alternatively, it is possible to easily know how the spin is applied. Therefore, it is possible to effectively practice ball games, such as tennis, in which the ball landing point is important. Specifically, various ball-practices can be practiced effectively by installing ball-practicing equipment at appropriate positions that match the purpose of the practice, such as near the net in the court, near the service line, and base line. Can do. Further, since the frame body 1 is supported at at least three points, the frame body 1 can be fixed on the support base 2 in a stable state. Further, this ball game training tool can be easily assembled using the parts of the frame 1, the support 2, the holder H, the support 6 and the base 7, and can be easily disassembled. Therefore, it can be stored compactly and is easy to transport.

〔第２実施形態について〕
第２実施形態に係る球技練習用具は、基本的な構成は第１実施形態と同様であるが、支持部３が前後方向に移動可能な構成となっている。したがって、図７に示すように、枠体１を任意の角度に固定することが容易となる。つまり、前後方向に回動させることができる。 [About the second embodiment]
The ball game practice tool according to the second embodiment has a basic configuration similar to that of the first embodiment, but has a configuration in which the support portion 3 is movable in the front-rear direction. Therefore, as shown in FIG. 7, it becomes easy to fix the frame 1 at an arbitrary angle. That is, it can be rotated in the front-rear direction.

図８（ａ）に示すように、支持台２の中央に、前後方向に向けて二つの長孔２５が設けられている。したがって、二つの長孔２５が平行に配置されている。図８（ｂ）及び（ｃ）に示すように、この実施の形態の支持部３は、平行に向かい合う板体の底部を結ぶ底板３２を有する断面略コの字状部材を、支持台２上に取り付けて支持部３を形成している。具体的には、断面略コの字状部材の底板３２を支持台２上に配置させる。この底板３２には、支持台２のそれぞれの長孔２５に対応する部分にそれぞれねじ孔３３が設けられている。このそれぞれのねじ孔３３と長孔２５とを対応させた状態でネジ等の接続部材３４に蝶ナット等の留め部材３５を螺合させて支持部３を支持台２に固定させている。したがって、長孔２５が支持台２の前後方向に向けて設けられているので、支持部３を支持台２の前後方向の適宜の位置に容易に移動させて固定することができる。 As shown in FIG. 8A, two long holes 25 are provided in the center of the support base 2 in the front-rear direction. Therefore, the two long holes 25 are arranged in parallel. As shown in FIGS. 8 (b) and 8 (c), the support portion 3 of this embodiment is a substantially U-shaped member having a bottom plate 32 that connects the bottom portions of plate members facing each other in parallel. The support part 3 is formed by attaching to the. Specifically, a bottom plate 32 having a substantially U-shaped cross section is disposed on the support base 2. The bottom plate 32 is provided with screw holes 33 at portions corresponding to the long holes 25 of the support base 2. A fixing member 35 such as a wing nut is screwed into a connection member 34 such as a screw in a state where the respective screw holes 33 and the long holes 25 correspond to each other, and the support portion 3 is fixed to the support base 2. Therefore, since the long hole 25 is provided in the front-rear direction of the support base 2, the support portion 3 can be easily moved and fixed to an appropriate position in the front-rear direction of the support base 2.

支持部３を前後方向に移動させる構成は、特に限定されるものではなく、例えば、図９（ａ）に示すように、前後方向に複数設けられた適宜のねじ孔２６に、支持部３となるピンを取り付けることによって、支持部３を移動させる構成とすることもできる。具体的には、支持台２の略中央に、平行となるように直線上に並べて複数のネジ孔２６が設けられている。図９（ｂ）及び（ｃ）に示すように、下方側にねじ切を設けたピンを、適宜のねじ孔２６に挿入し、蝶ナット等の留め部材２７を螺合させ、支持部３となるピンを支持台２に固定する。 The configuration for moving the support portion 3 in the front-rear direction is not particularly limited. For example, as shown in FIG. 9A, the support portion 3 and the appropriate screw hole 26 provided in the front-rear direction are connected to the support portion 3. It can also be set as the structure which moves the support part 3 by attaching the pin which becomes. Specifically, a plurality of screw holes 26 are provided in a substantially central position of the support base 2 so as to be parallel to each other. As shown in FIGS. 9B and 9C, a pin provided with a thread on the lower side is inserted into an appropriate screw hole 26, and a fastening member 27 such as a wing nut is screwed into the support portion 3. Fix the pin to the support 2.

以上のように、支持部３が支持台２の前後方向に移動する構成とすれば、枠体１の角度調整を容易に行うことができる。つまり、枠体１を前後方向に容易に回動させることができる。具体的には、図７に示すように、支持台２における、左右のホルダーＨＲ，ＨＬの貫通孔Ｈ１の位置よリも、前寄りに支持部３を配置させた場合、枠体１の重心がずれ、枠体１を後側に向けて回動させた状態で固定することができる。したがって、支持部３の位置を移動させることによって、枠体１の角度調整が容易にできる。 As described above, if the support portion 3 is configured to move in the front-rear direction of the support base 2, the angle adjustment of the frame body 1 can be easily performed. That is, the frame body 1 can be easily rotated in the front-rear direction. Specifically, as shown in FIG. 7, the center of gravity of the frame body 1 is obtained when the support portion 3 is arranged closer to the front than the position of the through holes H1 of the left and right holders HR and HL in the support base 2. The frame body 1 can be fixed in a state where the frame body 1 is shifted and rotated toward the rear side. Therefore, the angle adjustment of the frame 1 can be easily performed by moving the position of the support portion 3.

この実施の形態によれば、枠体１の角度を変化させることにより、練習に変化を持たせることができる。また、例えば、テニスのようなボールの着地点が非常に重要な球技の練習において、枠体１を後方側に回動させることによって、目的とする着地点を狙ってボールを打ち込む練習ができるので、特にボールにスピンをかける練習をより効果的に行うことが可能となる。 According to this embodiment, the practice can be changed by changing the angle of the frame 1. In addition, for example, in a ball game practice where the landing point of a ball such as tennis is very important, it is possible to practice driving the ball toward the target landing point by rotating the frame 1 backward. In particular, it is possible to more effectively practice spinning the ball.

〔第３実施形態について〕
第３実施形態に係る球技練習用具は、基本的な構成は、第１実施形態と同様であるが、以下の点で異なる。 [About the third embodiment]
The ball game practice tool according to the third embodiment has the same basic configuration as that of the first embodiment, but differs in the following points.

図１０に示すように、支持台２の左右方向の両端近傍がそれぞれ、上方に向かって傾斜する傾斜部２８を有する。この左右の傾斜部２８にそれぞれホルダー取付孔２１が設けられている。したがって、このホルダー取付孔２１にホルダーＨを取り付けた場合、支持台２が平坦な板体の場合と比べ、ホルダーＨの挟持部が上方に位置する。また、傾斜部２８の傾斜角度によって、左右のホルダー取付孔２１に取り付けられたホルダーＨがそれぞれ内側に向いた状態で取り付けられる。したがって、特に枠体１が環状体の場合、より安定した状態で枠体１を取り付けることが可能となる。また、環状体の枠体１の直径が小さい枠体１を固定する場合、支持台２に載置された枠体１の略接点部分Ｓ近傍の円弧の曲率が大きくなるが、このような枠体１であっても安定して取り付けることができる。また、枠体１を前後方向に傾斜しやすくなる。 As shown in FIG. 10, the vicinity of both ends in the left-right direction of the support base 2 has inclined portions 28 that are inclined upward. Holder attachment holes 21 are respectively provided in the left and right inclined portions 28. Therefore, when the holder H is attached to the holder attaching hole 21, the holding portion of the holder H is positioned above the support base 2 as compared with a flat plate. Further, depending on the inclination angle of the inclined portion 28, the holders H attached to the left and right holder attaching holes 21 are attached so as to face inward. Therefore, particularly when the frame body 1 is an annular body, the frame body 1 can be attached in a more stable state. Further, when the frame body 1 having a small diameter of the annular frame body 1 is fixed, the curvature of the arc near the substantially contact portion S of the frame body 1 placed on the support base 2 is increased. Even the body 1 can be attached stably. Moreover, it becomes easy to incline the frame 1 in the front-back direction.

以上、図面を参照しながら本発明の好適な実施形態を説明したが、例えば、前述した図５（ｃ）に示す断面略逆Ｕ字状のカバー部３６の端縁に板体３７を有する支持部３を、支持台２に対して移動可能な構成とする場合は、図１１に示すように、支持台２の長手方向の略中央位置に、支持台２の短手方向に向けて長孔２５を設けることで、支持部３を前後方向に移動させることができる。具体的には、支持部３の板体３７に設けられたねじ孔３３を長孔２５の適宜の位置に対応させ、蝶ねじ等の接続部材３４とナット等の留め部材３５によって適宜の位置に固定する構成とすることもできる。 The preferred embodiment of the present invention has been described above with reference to the drawings. For example, the support having the plate body 37 at the edge of the cover portion 36 having a substantially inverted U-shaped cross section shown in FIG. When the portion 3 is configured to be movable with respect to the support base 2, as shown in FIG. 11, a long hole is formed at a substantially central position in the longitudinal direction of the support base 2 toward the short direction of the support base 2. By providing 25, the support part 3 can be moved to the front-back direction. Specifically, the screw hole 33 provided in the plate body 37 of the support portion 3 is made to correspond to an appropriate position of the long hole 25, and the connecting member 34 such as a thumbscrew and a fastening member 35 such as a nut are placed at an appropriate position. It can also be set as the structure fixed.

このような構成の場合、支持台２の略中央位置に長孔２５が設けられるため、支持台２の下面略中央位置に接続部２２を設けることができない。よって、図１１（ａ）（ｂ）（ｃ）に示すように、支持台２における長孔２５が形成されていない部分、つまり、支持台２の長手方向略中央であって、支持台２の短手方向前方寄り又は後方寄りに接続部２２を設けることができる。 In the case of such a configuration, since the long hole 25 is provided at a substantially central position of the support base 2, the connection portion 22 cannot be provided at a substantially central position of the lower surface of the support base 2. Accordingly, as shown in FIGS. 11A, 11B, and 11C, the portion of the support base 2 where the long hole 25 is not formed, that is, the center of the support base 2 in the longitudinal direction, The connection part 22 can be provided at the front side or the rear side in the short direction.

また、接続部２２は、図１２（ａ）（ｂ）（ｃ）に示すように、断面Ｌ字状の固定板２２ａと固定部材２２ｂとを有する構成としてもよい。具体的には、固定板２２ａは、支持台２に当接させる当接板２２ｃと固定部材２２ｂを固定する接続板２２ｄによってＬ字状に形成される。当接板２２ｃには支持台２と接続するための接続部材８１が貫通する孔８２が設けられており、固定板２２ａには、固定部材２２ｂを接続するためのねじ孔８３が、固定板２２ａの下側寄りに設けられている。このねじ孔８３は、接続部２２に接続される支柱６の長手方向に対して略垂直方向に向けて直線状に並べて２箇所設けられている。固定部材２２ｂは、断面円弧部と円弧部８４の両端縁にそれぞれ板体８５が設けられ断面略ギリシャ文字のオメガのような形状をした部材とすることができる。このそれぞれの板体８５には、固定板２２ａに設けられたねじ孔８３に対応する位置に、ねじ孔８７が設けられている。 Moreover, the connection part 22 is good also as a structure which has the cross-sectional L-shaped fixing plate 22a and the fixing member 22b, as shown to Fig.12 (a) (b) (c). Specifically, the fixing plate 22a is formed in an L shape by a contact plate 22c that contacts the support base 2 and a connection plate 22d that fixes the fixing member 22b. The contact plate 22c is provided with a hole 82 through which the connection member 81 for connecting to the support base 2 passes, and the fixing plate 22a has a screw hole 83 for connecting the fixing member 22b to the fixing plate 22a. It is provided on the lower side. The screw holes 83 are provided in two locations arranged in a straight line in a direction substantially perpendicular to the longitudinal direction of the column 6 connected to the connection portion 22. The fixing member 22b may be a member having a plate-like body 85 provided at both end edges of the cross-section arc portion and the arc portion 84 and having a shape like an omega having a substantially Greek letter in cross section. Each plate body 85 is provided with a screw hole 87 at a position corresponding to the screw hole 83 provided in the fixed plate 22a.

支持台２に固定板２２ａの当接板２２ｃを接続部材８１によって固定し、支柱６の他端側を当接板２２ｃに当接した状態にて、固定部材２２ｂの円弧部８４に支柱６を配置させた状態で、固定部材２２ｂのそれぞれの板体８５を接続板２２ｄに接続部材８６によって固定することで、支柱６と支持台２とを接続することもできる。 In the state where the contact plate 22c of the fixed plate 22a is fixed to the support base 2 by the connecting member 81 and the other end side of the support 6 is in contact with the contact plate 22c, the support 6 is mounted on the arc portion 84 of the fixed member 22b. It is also possible to connect the support column 6 and the support base 2 by fixing each plate body 85 of the fixing member 22b to the connection plate 22d with the connection member 86 in the arranged state.

また、図１２（ａ）に示すように、ホルダー取り付け孔２１の形状を円形とすることもできる。このような構成にすれば、ホルダーＨがホルダー取付孔２１内において回動可能となり、ホルダーＨの取り付け位置を微調整することが容易となる。したがって、形状、大きさ等の異なる種々の枠体１に対応しやすくなる。また、枠体１を任意の角度に傾斜させた状態で挟持し易くなる。なお、この構成の場合、ホルダー取付孔２１の直径が、取付孔長さＬ４に相当する。 Moreover, as shown to Fig.12 (a), the shape of the holder attachment hole 21 can also be made circular. With such a configuration, the holder H can be rotated in the holder mounting hole 21, and it is easy to finely adjust the mounting position of the holder H. Therefore, it becomes easy to deal with various frame bodies 1 having different shapes and sizes. Moreover, it becomes easy to hold | grip the frame 1 in the state inclined to arbitrary angles. In this configuration, the diameter of the holder mounting hole 21 corresponds to the mounting hole length L4.

また、図１１（ｃ）に示すように、ホルダーＨの第１挟持部４１と第２挟持部５１とに、それぞれ内側に向けて突起５３を設けない構成とすることもできる。 Moreover, as shown in FIG.11 (c), it can also be set as the structure which does not provide the processus | protrusion 53 in the 1st clamping part 41 and the 2nd clamping part 51 of the holder H toward each inside.

また、支持台２の略中央に支持部３を複数個設ける構成とすることもできる。具体的には、図１２に示すように、支持台２の略中央に、前後方向に向けて二つの長孔２５を設ける。したがって、二つの長孔２５が平行に配置される。この二つの長孔２５の適宜の位置に、二つの支持部３をそれぞれ、蝶ネジ等の接続部材３４と蝶ナット等の留め部材３５よって固定すれば、二つの支持部３を前後方向に移動可能に取り付けることができる。このようにすれば、枠体１を、二つの支持部３、右側ホルダーＨＲ及び左側ホルダーＨＬの４点で支持することとなり、枠体１をより安定した状態にて支持台３に固定することができる。 Further, a plurality of support portions 3 may be provided in the approximate center of the support base 2. Specifically, as shown in FIG. 12, two long holes 25 are provided in the approximate center of the support base 2 in the front-rear direction. Accordingly, the two long holes 25 are arranged in parallel. If the two support portions 3 are fixed at appropriate positions of the two long holes 25 by connecting members 34 such as wing screws and fastening members 35 such as wing nuts, the two support portions 3 are moved in the front-rear direction. Can be attached as possible. In this way, the frame body 1 is supported at the four points of the two support portions 3, the right holder HR, and the left holder HL, and the frame body 1 is fixed to the support base 3 in a more stable state. Can do.

以上のとおり、本発明の趣旨を逸脱しない範囲内で、種々の追加、変更又は削除が可能である。したがって、そのようなものも本発明の範囲内に含まれる。 As described above, various additions, changes, or deletions are possible without departing from the spirit of the present invention. Therefore, such a thing is also included in the scope of the present invention.
