Description

本発明は、テニスの練習でコートにころがった大量のボールを、テニスの技術とフォームで素早く上品に拾うための、テニスの携帯球ひろいラケットに関するものである。  The present invention relates to a tennis racket racket for quickly and elegantly picking up a large number of balls that have fallen on a court in tennis practice using tennis technique and form.

技術背景Technical background

従来、テニスボールを拾うのに、まずしゃがんでボールを集め、ラケットのガット面にのせて、かごに運び入れていた。  Conventionally, to pick up a tennis ball, first squatting and collecting the ball, placing it on the gut surface of the racket and bringing it into the basket.

それには次のような問題点があった。
しゃがんで拾うため、腰に負担がかかって辛く、拾う姿は格好が悪いうえ、品もなかった。ラケットを汚したり傷つけたりした。テニスの上達に球拾いは無関係であった。
本発明は、以上の問題を解決しようとするものである。
There were the following problems.
The squat picks up and puts a strain on the hips, and the appearance of picking up was unsatisfactory and lacking quality. Dirty or damaged the racket. Picking up the ball was irrelevant to improving tennis.
The present invention is intended to solve the above problems.

二枚並べたフレーム板5の、前端を連結コマ4の溝に差し込み、それぞれ、固定ピン8を支点にして連結させる。後端を互いに反対方向に等分にねじって、グリップケース2内を摺動する中子6にもうけた取付部14に取り付ける。間に、網袋7の開口部を取り付け、網袋をたたんで、全体をグリップケース2に、押し込んで収納する。これを使用するときは、連結コマ4を持ってフレーム板5を引き出し、固定ピン8を支点に開口させ、ラケットのフレーム部を形成させると共に、網袋7を開口させてセットする。これをテニスのフォームで振り、フレーム部でボールの下半球を狙い打ち、ボールを回転させて網袋7に転がし入れる。以上を特徴とする、テニスの携帯球ひろいラケットである。  The front ends of the two frame plates 5 are inserted into the grooves of the connecting pieces 4 and are connected using the fixing pins 8 as fulcrums. The rear ends are equally twisted in opposite directions and attached to the attachment portion 14 provided on the core 6 that slides in the grip case 2. In the middle, the opening of the net bag 7 is attached, the net bag is folded, and the whole is pushed into the grip case 2 and stored. When this is used, the frame plate 5 is pulled out by holding the connecting piece 4, and the fixing pin 8 is opened at the fulcrum to form the frame portion of the racket, and the net bag 7 is opened and set. This is shaken with a tennis form, hits the lower hemisphere of the ball with the frame part, rotates the ball and rolls it into the net bag 7. This is a tennis racket wide racket characterized by the above.

本発明は、トップスピン、ストレート、スライス等テニスの技術で球拾いができるから、ボールを打つ時の打点技術が向上する。また、立ったまま楽に拾えるので腰の負担も解消できる。フォアハンドやバックハンドの美しいフォームで素早く球拾いができ、その姿が上品である。姿が上品なことから、練習では着ることが難しかったスコート、ワンピースも気兼ねなく着ることができる。練習がファッショナブルで楽しいものとなる。こうして、球拾いに新しく上品なスタイルが生まれ、イメージが向上する。試作した結果、重さが約200gと軽く、長さ42cmとラケットより30cm短く携帯に便利である。  According to the present invention, since the ball can be picked up by tennis techniques such as top spin, straight, and slice, the hitting technique when hitting a ball is improved. Also, you can easily pick up while standing, so you can eliminate the burden on your waist. Balls can be quickly picked up with beautiful forehand and backhand forms, and their appearance is elegant. Because of its elegant appearance, you can wear scoats and dresses that were difficult to wear in practice. Practice is fashionable and fun. In this way, a new and elegant style for picking up balls is born and the image is improved. As a result of the trial manufacture, the weight is as light as about 200 g, and the length is 42 cm, which is 30 cm shorter than the racket, and is convenient to carry.

以下、本発明の実施の形態を説明する。
(イ)グリップケース2に、中子6の位置を決めるための、位置ぎめ穴10を設ける。
(ロ)グリップケース2内を摺動する中子6の前方に、フレーム板5を取り付けるための取付部14を設け、後方には位置決めの段ピン12を設ける。
(ハ)グリップエンド1に、空気穴13を設ける。
(ニ)グリップケース2に蓋をするキャップ3を設ける。
(ホ)コの字形の連結コマ4の溝の下面両端に、小さな突起9を設ける。
(ヘ)2枚並べたフレーム板5の、前端を連結コマ4の溝に差し込み、それぞれ固定ピン8を支点にして連結させる。後端を互いに反対方向に等分にねじって、グリップケース2内を摺動する中子6の取付部14に取り付ける。間に、網袋7の開口部を取り付け、網袋7をたたみ、全体をグリップケース2に押し込んで収納し、キャップ3で蓋をする。
(ト)これを、球ひろいができるようにセットするには、まず、キャップ3を取り、連結コマ4を持って、段ピン12が位置ぎめ穴10に、はまるまで引き出す。次に、連結コマ4をグリップケース2の前端面と平行になるまで押し下げる。このときフレーム板5は、弓なりに曲がると共に図2のように、固定ピン8を支点として左右に開口する。さらに矢じるしの方向に押せば、フレーム板5は、それぞれ、連結コマ4の溝を広げて、突起9を乗り越し、パチンと溝の底に位置決めされ直列となって全開する。こうして、ねじれがゼロとなり輪となったフレーム板5は、グリップケース2の前端で強くしぼられ、くびれを作って、テニスのラケットに似たフレーム部を形成すると共に、網袋7を開口して、図3のようにセットされる。
(チ)連結コマに設けた小さな突起9は、フレーム板5の位置を決めると共に、簡単には戻らなくして、安全性を高めたものである。
(リ)フレーム板5の前端は、開閉の障害にならないよう、あらかじめ丸く面取りをしておく。フレーム板5の後端を、向かい合った縁が上になるように互いに90度反対方向にねじって、中子6に取り付けてある。これは、開口方向を決めると共に開口させやすくして、全開時には、ねじれをゼロにするためである。フレーム板5は、バネ板で薄くできているため、グリップケース2でしぼられると美しいフレームラインが形成される。また、その薄さゆえラケットを傾けても、ボールを打つことができるから、トップスピン、スライス等の技術を使うことができる。その上、フレーム板5を開口した時の大きさが、テニスのラケットのスウィートスポットより少し大きいくらいであるから、小さいラケットで、小さい的を打つことになり、技術の向上が見込める。
(ヌ)中子6に、もうけた取付部14は、ねじれ角が90度の場合を示している。フレーム板5の強さによっては、もっと小さい角度で取り付ける必要がある。こういう場合、取付部14をねじれ角に合わせて台形などにしただけでは、フレーム板5の全開時、ねじれをゼロにできない。しかし、これは、フレーム板5の後端を長穴にしてゆるやかに取り付けることで解決できる。ねじれがゼロになれば、フレーム板5は、グリップケース2の前端のアール部にぴたりと合ってしぼられ、ガタなくフレーム部が形成される。
(ル)グリップエンド1の空気穴13は、空気抜きの他に、中子6のスピードを調節したり、押さえて止めたりと安全にセットするためのものである。
(オ)網袋7の開口部は、フレーム板5の全開時の形に合わせて取り付け、閉じた時のフレーム板5の隙間は、網袋7の取付代を見込んである。
(ワ)試作品における、主な部品の材質を記載する。グリップケース2は、アルミニウムの形成品。フレーム板5は、鋼のバネ板。連結コマ4は、ステンレス鋼。中子6、グリップエンド1、キャップ3は、プラスチック。
本発明は、以上の構成よりなっている。
本発明を使用するときは、まず、キャップ3を取り、連結コマ4を持ってフレーム板5を引き出し、曲げ押して瞬時に開口させ、フレーム部を形成させると共に、網袋7を開口させ、図3のようにセットする。これをテニスのフォームで振り、フレーム部でボールの下半球を狙い打つと、ボールは表面の繊維がこすられて回転し、網袋7の底に向かって転がり込む。このようにしてフォアハンドやバックハンドで、フラット、トップスピン、スライスと打ち分けて拾ったり、ローボレーやハーフボレーのフォームで打ち拾ったりして、これをかごに運び入れる。使用後は、連結コマ4を水平に引いて、フレーム部を原形にもどし、押し込んで収納する。
Embodiments of the present invention will be described below.
(A) A positioning hole 10 for determining the position of the core 6 is provided in the grip case 2.
(B) A mounting portion 14 for mounting the frame plate 5 is provided in front of the core 6 that slides in the grip case 2, and a positioning step pin 12 is provided in the rear.
(C) An air hole 13 is provided in the grip end 1.
(D) A cap 3 that covers the grip case 2 is provided.
(E) Small protrusions 9 are provided at both ends of the groove of the U-shaped connecting piece 4.
(F) Insert the front ends of the two frame plates 5 arranged in the groove of the connecting piece 4 and connect them using the fixing pins 8 as fulcrums. The rear ends are twisted equally in opposite directions and attached to the attachment portion 14 of the core 6 that slides in the grip case 2. In the middle, the opening of the net bag 7 is attached, the net bag 7 is folded, the whole is pushed into the grip case 2 and stored, and the cap 3 is covered.
(G) To set the ball so that it can be expanded, first remove the cap 3, hold the connecting piece 4, and pull out the step pin 12 into the positioning hole 10 until it is fitted. Next, the connecting piece 4 is pushed down until it becomes parallel to the front end face of the grip case 2. At this time, the frame plate 5 bends like a bow and opens left and right with the fixing pin 8 as a fulcrum as shown in FIG. When pressed further in the direction of the arrow, the frame plate 5 widens the groove of the connecting piece 4, passes over the protrusion 9, is positioned at the bottom of the snap and the groove, and is fully opened in series. In this way, the frame plate 5 in which the torsion becomes zero and becomes a ring is strongly squeezed at the front end of the grip case 2 to form a constriction, forming a frame portion similar to a tennis racket, and opening the net bag 7. Are set as shown in FIG.
(H) The small protrusions 9 provided on the connecting pieces determine the position of the frame plate 5 and are not easily returned to improve safety.
(I) The front end of the frame plate 5 is chamfered in advance so as not to obstruct the opening and closing. The rear end of the frame plate 5 is attached to the core 6 by twisting them in opposite directions by 90 degrees so that the opposite edges are on top. This is to determine the opening direction and make it easy to open, so that the twist is zero when fully opened. Since the frame plate 5 is made of a spring plate, a beautiful frame line is formed when it is squeezed by the grip case 2. Further, since the ball can be hit even if the racket is tilted due to its thinness, techniques such as top spin and slicing can be used. In addition, since the size when the frame plate 5 is opened is slightly larger than the sweet spot of the tennis racket, a small target can be hit with a small racket, and improvement in technology can be expected.
(N) The mounting portion 14 provided on the core 6 shows a case where the twist angle is 90 degrees. Depending on the strength of the frame plate 5, it may be necessary to attach it at a smaller angle. In such a case, the twist cannot be made zero when the frame plate 5 is fully opened only by making the mounting portion 14 a trapezoid or the like according to the twist angle. However, this can be solved by gently attaching the rear end of the frame plate 5 to a long hole. When the twist becomes zero, the frame plate 5 is squeezed into the rounded portion at the front end of the grip case 2 and the frame portion is formed without play.
(L) The air holes 13 of the grip end 1 are for setting the speed of the core 6 in addition to removing air, or for safely setting it by holding it down.
(E) The opening of the mesh bag 7 is attached in accordance with the fully opened shape of the frame plate 5, and the clearance of the frame plate 5 when closed is expected to allow for the attachment of the mesh bag 7.
(W) Describe the material of the main parts in the prototype. The grip case 2 is formed of aluminum. The frame plate 5 is a steel spring plate. The connecting piece 4 is stainless steel. The core 6, the grip end 1, and the cap 3 are plastic.
The present invention has the above configuration.
When using the present invention, first, the cap 3 is removed, the frame 5 is pulled out by holding the connecting piece 4, bent and pressed to open it instantaneously to form the frame portion, and the net bag 7 is opened, and FIG. Set like this. When this is swung with a tennis form and hits the lower hemisphere of the ball with the frame part, the ball rotates by rubbing the surface fibers and rolls toward the bottom of the net bag 7. In this way, the forehand and backhand are picked up by flat, topspin and slice, or picked up in the form of a low volley or half volley and brought into the basket. After use, the connecting piece 4 is pulled horizontally, the frame part is returned to its original shape, and pushed in for storage.

網袋7の網目を魚用や昆虫用に変更、グリップケースの大きさを、それぞれに合わせると、容易に魚をすくう網、捕虫網を携帯化できる。  If the net of the net bag 7 is changed to fish or insect, and the size of the grip case is adjusted to each, the net for scooping fish and the insect net can be easily carried.
