Abstract

(57)【要約】 本発明は、低沸点有機溶剤中濃度１〜５０％のレツェンテ樹脂又は化石質樹脂の溶液からなる、緊張されたガットを有するラケットのための被覆剤に関する。   (57) [Summary] The present invention relates to a coating for racquets having a strained gut, comprising a solution of a rezente resin or a fossil resin at a concentration of 1 to 50% in a low boiling organic solvent.

Description

【発明の詳細な説明】 緊張されたガットを有するラケット用被覆剤 本発明の目的は、ラケットによるボール運びを改善することができるテニスラ ケット、スカッシュラケット又はバトミントンラケット用の新規被覆剤である。 緊張されたガットを有するラケット、例えばテニスラケット、スカッシュラケ ット又はバトミントンラケット（後記では「テニスラケット」と呼ぶ）は通常、 正確な角度で交差し、その素材、弾性及び張力がゲームの性質に重要である縦方 ガット及び横方ガットを張られている。当初使用された腸製ガットは殊に多くの スポーツで、今日ではますますプラスチックガットに換えられており、それとい うのも、これはかなり簡単に、かつ価格的に有利に製造することができるためで ある。しかしプラスチックガットは、比較的かなり平滑な表面を有し、その結果 、ボール運びはあまり良くない。腸製ガットでも、プラスチックガットでも、ス ピン又は旋回伴って打たれるショットは、横方圧力を縦方ガットにもたらし、そ の結果、その位置からずれて、緊張の弾性特性が代わり、かつボール運びはもは や正確ではない。いったんずれたガットは、後のショットでの相応する反力によ って再び均一になることは稀であるので、プレーヤーは打ち合いの終了後に初め て、張りを再び直して、理想的なヒット特性を再び生じさせることができる。 従って、課題は、一方で、ラケットによるボール運びを改善し、かつ他方で、 旋回を伴うショットによるガットのずれを阻止する可能性を発見することである 。 この課題は、メインクレームの特徴により解決され、かつ従属請求項により改 善される。 本発明では、ラケットのガットを殊に、ボール運びに特に重要な中心位置で、 レツェンテ樹脂(rezente Harze)又は化石質樹脂の溶液で薄く被覆し、かつ溶剤 を蒸発させる。残留した非常に薄い塗膜により、ガット相互のより良好な付着が 生じて、それほど簡単にはその位置から横方の力により動かされない、即ち、ス ピンを伴ったボールでもずれない。更に、ガットと打たれるボールとの接触も強 まり、ボールはより良好に送られ、従って、正確なヒット技術が可能になる。 樹脂としては殊に、針葉樹からのバルサムの蒸留残留物として得られ、かつラ ッカー、塗料、印刷用インキ、セッケン、接着剤を製造するための技術で、接着 の際の融剤として、バイオリンの弓の塗布等で使用されるロジンを選択する。ロ ジンは多くの有機溶剤に可溶性である。本発明の目的には、溶剤として、全ての 易揮発性溶剤がこれに該当する。ラケットに噴霧する場合に、蒸発した溶剤を部 分的に吸入しうるので、溶 剤は可能な限り健康に問題のないものであるべきである。エタノール、イソプロ パノール、アセトン、メチルエチルケトン及び酢酸エチルエステルが従って特に 有利である。 ロジンの代わりに、その特性、例えば硬度、溶融特性及び軟化特性、可溶性が ロジンに類似しているその他のレツェンテ又は化石質樹脂も使用することができ る。カナダバルサム、ペルーバルサム又は漆を木質樹脂として、シェラックを動 物に由来する重要な樹脂として、かつモンタン樹脂もしくはモンタンワックスを 化石質樹脂として挙げることができる。 例えば、誘導体化又は不飽和化合物、例えばマレイン酸又はフマル酸の添加に よりロジンの軟化点を７０〜８０℃に高めるのが有利であると判明しており、こ れにより、溶剤の蒸発の後に残留する塗膜が迅速に「乾燥」状態をもたらす（Ro empps Chemie‐Lexikon，9．Aufl.，p2305‐2306参照）。 使用される樹脂を、１〜５０％、有利に２〜２０％溶液（ｇ／ｍｌ）として使 用し、その際、約２〜５％溶液を噴霧するのが有利である。濃溶液は、ガット表 面上での樹脂の均一な分布を可能にするには、その粘度が高くなりすぎ、かつ施 与される溶液の量も僅かすぎるという欠点を有する。低すぎる濃度は、大量の溶 液を施与せねばならず、その結果大量の溶剤が過剰に蒸発するという欠点を有す る。約２〜５％の有利な範 囲が、双方の限界値の間の特に有利な妥協と判明している。 本発明の溶液を有利にスプレーとして施与し、その際、加圧ビン中での施与が 可能であるが、環境的な理由から、化粧品で慣用の噴出気を供給媒体として使用 するポンプ機構が有利である。 本発明では、ラケットに一度丁寧に、４〜５％溶液０．５〜１ｃｍ3で十分な 本発明のスプレー液を噴霧し、かつその後、ゲーム中に生じる樹脂の磨耗を、必 要な間隔で溶液０．１〜０．５ｍｌを用いての後スプレーにより補う。 本発明の溶液の噴霧は特に簡単で、場合によりゲームコート上で実施すること ができるが、勿論、相応する濃度の溶液を、ブラシで直接ガットに施与するか、 又はこれをラケットに張る前に溶液中に浸し、浸漬することも可能である。均一 な最初の施与にはその場合、大量のロジンの施与を必要とするので、この場合に は、濃度５〜２０％が有利である。この塗布技術は殊に、ラケットの予備製造の 際に有意義であり、それというのもその場合には、無駄に樹脂をガットに「通過 噴霧」しないためである。 フマル酸及び／又はマレイン酸の使用はその場合、特に有利と判明しており、 それというのも、それにより樹脂の軟化点が高まり、被覆されたガットの表面が より乾いて（粘着性が少なく）見えるだけでなく、例 えば５０％（ｇ／ｍｌ）までの濃溶液も使用することができるためである。The present invention is directed to a novel coating for tennis, squash or badminton racquets which can improve balling by racquets. Rackets with strained guts, such as tennis racquets, squash racquets or badminton racquets (hereinafter referred to as "tennis racquets") usually intersect at precise angles, and the material, elasticity and tension are important to the nature of the game. There are some vertical and horizontal guts. The gut guts originally used were replaced, especially in many sports, today with plastic guts, because they can be manufactured quite simply and cost-effectively. It is. However, plastic gut has a relatively fairly smooth surface, and consequently ball movement is not very good. In both intestinal and plastic guts, shots that are hit with spin or swirl introduce lateral pressure into the vertical gut, which shifts from its position, replacing the elastic properties of tension and ball movement. No longer accurate. It is rare for a displaced gut to re-equalize due to the corresponding reaction force in later shots, so that the player can only re-establish tension after the end of the match to re-establish ideal hit characteristics be able to. The challenge, therefore, is to find the possibility, on the one hand, of improving the ball transport by the racquet and, on the other hand, of preventing the gut from being displaced by shots with turning. This problem is solved by the features of the main claim and improved by the dependent claims. According to the invention, the gut of the racket is coated thinly with a solution of rezente resin or fossil resin and the solvent is evaporated, especially in the central position, which is particularly important for ball transport. The remaining very thin coating results in better adhesion of the guts to each other and is not so easily moved from its position by lateral forces, i.e. it does not slip even with spinning balls. Further, the contact between the gut and the ball being hit is increased, and the ball is better delivered, thus allowing for an accurate hit technique. Especially as a resin, it is obtained as a residue of distillation of balsam from conifers and is a technique for producing lacquers, paints, printing inks, soaps and adhesives. Select rosin to be used for application of Rosin is soluble in many organic solvents. For the purposes of the present invention, all volatile solvents correspond to this as solvent. When spraying the racket, the solvent should be as health-friendly as possible, as the evaporated solvent can be partially inhaled. Ethanol, isopropanol, acetone, methyl ethyl ketone and ethyl acetate are therefore particularly advantageous. Instead of rosin, other rezente or fossil resins whose properties, for example hardness, melting and softening properties, solubility are similar to rosin, can also be used. Canadian balsam, Peruvian balsam or lacquer can be mentioned as a wood resin, shellac as an important resin derived from animals, and montan resin or montan wax as a fossil resin. For example, it has been found to be advantageous to increase the softening point of the rosin to 70-80 ° C. by the addition of derivatized or unsaturated compounds, such as maleic acid or fumaric acid, which remains after evaporation of the solvent. The coating quickly gives a "dry" state (see Roemps Chemie-Lexikon, 9. Aufl., P2305-2306). The resin used is used as a 1 to 50%, preferably 2 to 20% solution (g / ml), it being advantageous to spray approximately 2 to 5% solution. Concentrated solutions have the disadvantage that their viscosity is too high and the amount of solution applied is too small to allow a uniform distribution of the resin on the gut surface. Concentrations that are too low have the disadvantage that large volumes of solution have to be applied, with the consequence that large volumes of solvent evaporate excessively. An advantageous range of about 2 to 5% has proven to be a particularly advantageous compromise between both limits. The solution according to the invention is advantageously applied as a spray, in which case it is possible to apply in a pressurized bottle, but for environmental reasons a pump mechanism which uses the customary bleeding air as supply medium for cosmetics Is advantageous. In the present invention, the racket is carefully sprayed once with a sufficient spray liquid of the present invention with 0.5 to 1 cm 3 of a 4 to 5% solution, and thereafter, the abrasion of the resin generated during the game is performed at required intervals. Make up by post-spray using 0.1-0.5 ml. The spraying of the solution according to the invention is particularly simple and can optionally be carried out on the game court, but of course the solution of the corresponding concentration is applied directly to the gut with a brush or before it is put on a racket. It is also possible to immerse in the solution and to immerse. A uniform initial application then requires the application of large amounts of rosin, so that a concentration of 5 to 20% is advantageous in this case. This application technique is particularly useful in the pre-production of rackets, since in that case the resin is not "pass-sprayed" on the gut unnecessarily. The use of fumaric acid and / or maleic acid has proved to be particularly advantageous in that case, because it increases the softening point of the resin and makes the surface of the coated gut dry (less tacky). This is because not only visible but also concentrated solutions, for example up to 50% (g / ml), can be used.
