A coating agent for stringed rackets consists of a solution of a recent or fossil resin in a concentration of 1-50 % in a low-boiling organic solvent.

Description

Beschichtungsmittel für Schläger mit Saitenbespannung Coating agent for strings with string covering
Gegenstand der vorliegenden Erfindung ist ein neues Beschichtungsmittel für Tennis-, Squash- oder Badmintonschläger, welches in der Lage ist, die Ballfüh¬ rung durch den Schläger zu verbessern.The present invention relates to a new coating composition for tennis, squash or badminton rackets, which is capable of improving the ball guidance by the racket.
Schläger mit Saitenbespannung, wie z.B. Tennis-, Squash- oder Badminton¬ schläger, im folgenden "Tennisschläger" genannt, werden üblicherweise mit Längs- und Quersaiten bespannt, welche sind in einem rechtem Winkel kreuzen, wobei das Material der Saite, seine Elastizität und die Spannkraft wesentlich für die Spieleigenschaften sind. Die ursprünglich verwendeten Darmsaiten werden insbesondere im Breitensport heute zunehmend durch Kunststoffsaiten ersetzt, da sie wesentlich einfacher und preiswerter herzustellen sind. Die Kunststoffsaite hat jedoch eine vergleichsweise wesentlich glattere Oberfläche, so daß die Ballfüh¬ rung weniger gut ist. Sowohl bei Darmsaiten als auch bei Kunststoffsaiten führen Schläge, die mit einem Spinn oder Drall geschlagen werden, zu einem Seitwärts¬ druck auf die Längssaiten, so daß diese sich aus ihrer Lage verschieben, wodurch sich die Federungseigenschaften der Bespannung verändern und die Ballführung nicht mehr präzise ist. Da die einmal verschobenen Saiten nur selten durch ent¬ sprechende Gegenkräften bei späteren Schlägen wieder ausgeglichen wird, kann der Spieier erst nach Beendigung des Schlagwechsels die Bespannung wieder einrichten und somit die idealen Schlagverhältnisse wieder herstellen.Strings with string covering, e.g. Tennis, squash or badminton rackets, hereinafter referred to as "tennis rackets", are usually strung with longitudinal and cross strings which cross at right angles, the material of the string, its elasticity and the tension being essential for the playing characteristics . The gut strings originally used are increasingly being replaced by plastic strings, especially in popular sports, since they are much easier and cheaper to manufacture. However, the plastic string has a comparatively much smoother surface, so that the ball guidance is less good. In the case of gut strings as well as plastic strings, strikes which are struck with a spinning or twisting lead to sideways pressure on the main strings, so that they move out of position, which changes the suspension properties of the stringing and the ball guidance is no longer precise is. Since the strings once shifted are rarely compensated for by corresponding counterforces in later beats, the spier can only re-establish the stringing after the end of the change of beats and thus restore the ideal beating conditions.
Es stellte sich daher die Aufgabe, eine Möglichkeit zu finden, die einerseits die Ballführung durch den Schläger verbessert und andererseits eine Verschiebung der Saiten durch Schläge mit einem Drall zu verhindern.It was therefore the task to find a way which on the one hand improves the ball guidance by the racket and on the other hand prevents the strings from being displaced by strikes with a twist.
Diese Aufgabe wird durch die Merkmale der Hauptansprüche gelöst und durch die der Unteransprüche verbessert.This object is achieved by the features of the main claims and improved by those of the subclaims.
Erfindungsgemäß werden die Saiten des Schlägers, insbesondere in dem für die Ballführung besonders wichtigen zentralen Bereich, dünn mit einer Lösung eines rezenten oder fossilen Harzes beschichtet und das Lösemittel verdunstet. Der zurückbleibende, sehr dünne Film bewirkt eine bessere Haftung der Saiten anein¬ ander, so daß diese durch Querkräfte nicht so leicht aus ihrer Lage gebracht wer¬ den, d.h. bei einem Ball mit Spinn nicht verrutschen. Weiterhin wird auch der Kontakt zwischen Saite und zu schlagendem Ball verstärkt, so daß der Ball besser geführt wird und damit eine präzisere Schlagtechnik erlaubt.According to the invention, the strings of the racket are coated thinly with a solution of a recent or fossil resin, in particular in the central area which is particularly important for the ball guidance, and the solvent evaporates. The remaining, very thin film causes the strings to adhere better to one another, so that they are not easily moved out of position by transverse forces, ie they do not slip on a ball with spinning. Furthermore, the contact between the string and the ball to be struck is strengthened, so that the ball is guided better and thus allows a more precise striking technique.
Als Harz hat sich insbesondere Kolophonium bewährt, welches als Destillations¬ rückstand des Balsams aus Nadelhölzern gewonnen wird und in der Technik zur Herstellung von Lacken, Anstrichen, Druckfarben, Seifen, Klebstoffen, als Flußmit¬ tel beim Löten, zum Bestreichen von Geigenbögen etc. verwendet wird. Kolopho¬ nium ist in vielen organischen Lösungsmitteln löslich. Für den erfindungsgemäßen Zweck kommen als Lösungsmittel alle leicht flüchtigen Lösungsmittel in Frage. Da beim Besprühen der Schläger das verdampfende Lösungsmittel teilweise einge¬ atmet werden könnte, sollte das Lösemittel möglichst gesundheitlich verträglich sein. Ethanol, Isopropanol, Aceton, Methylethylketon und Essigsäureethylester werden daher besonders bevorzugt.Rosin, which is obtained from coniferous wood as a distillation residue of the balm and is used as a resin and has been used in technology for the production of lacquers, paints, printing inks, soaps, adhesives, as a flux during soldering, for coating violin bows etc. becomes. Colophonium is soluble in many organic solvents. All readily volatile solvents are suitable as solvents for the purpose according to the invention. Since the evaporating solvent could be partially inhaled when the clubs were sprayed, the solvent should be as health-compatible as possible. Ethanol, isopropanol, acetone, methyl ethyl ketone and ethyl acetate are therefore particularly preferred.
Anstelle von Kolophonium lassen sich auch andere rezente oder fossile Harze einsetzen, die in den Eigenschaften wie Härte, Schmelz- und Erweichungseigen¬ schaften, Löslichkeit dem Kolophonium ähnlich sind. Kanadabalsam, Perubalsam oder Japanlack seien als Beispiele von Baumharzen, Schellack als wichtigstes Harz tierischen Ursprungs, und Montanharz bzw. Montanwachs als fossile Harze genannt.Instead of rosin, other recent or fossil resins can be used, which are similar to rosin in properties such as hardness, melting and softening properties, and solubility. Canada balsam, Peru balsam or Japanese lacquer are examples of tree resins, shellac as the most important resin of animal origin, and montane resin or montan wax as fossil resins.
Als vorteilhaft hat sich erwiesen, den Erweichungspunkt des Kolophoniums von 70 - 80°C, z. B. durch Derivatisierung oder Zusatz von ungesättigten Verbindun¬ gen wie Maleinsäure oder Fumarsäure, zu erhöhen, wodurch der nach dem Ab¬ dunsten des Lösungsmittels verbleibende Film schneller ein "trockenes" Gefühl vermittelt (vgl. Römpps Chemie-Lexikon, 9. Aufl., S. 2305 - 2306).It has proven to be advantageous to reduce the rosin softening point from 70 - 80 ° C, e.g. B. by derivatization or addition of unsaturated compounds such as maleic acid or fumaric acid, whereby the film remaining after evaporation of the solvent gives a "dry" feeling faster (cf. Römpps Chemie-Lexikon, 9th ed., Pp. 2305 - 2306).
Die verwendeten Harze werden als 1-50%ige, vorzugsweise 2 - 20%ige, Lösung (g/ml) eingesetzt, wobei etwa 2-5 %ige Lösungen zum Sprühen bevorzugt sind. Konzentrierte Lösungen haben den Nachteil, daß ihre Viskosität zu groß wird und auch die aufzutragende Menge der Lösung zu gering wird, um eine gleichmäßige Verteilung des Harzes über die Oberfläche der Saite zu erlauben. Zu niedere Konzentrationen haben den Nachteil, daß zu große Mengen der Lösung aufgetra¬ gen werden müssen, so daß große Mengen Lösemittel überflüssig verdampft werden. Der bevorzugte Bereich zwischen etwa 2 und 5 % hat sich als besonders günstiger Kompromiß zwischen beiden Grenzwerten erwiesen.The resins used are used as 1-50%, preferably 2-20%, solution (g / ml), with about 2-5% solutions being preferred for spraying. Concentrated solutions have the disadvantage that their viscosity becomes too large and the amount of solution to be applied is too small to be uniform Allow resin to spread over the surface of the string. Concentrations which are too low have the disadvantage that excessive amounts of the solution have to be applied, so that large amounts of solvent are evaporated unnecessarily. The preferred range between about 2 and 5% has proven to be a particularly favorable compromise between the two limit values.
Die erfindungsgemäße Lösung wird bevorzugt als Spray aufgetragen, wobei die Applikation in einer Druckflasche möglich ist, aus Umweltgründen jedoch ein in der Kosmetik üblicher Pumpmechanismus, welcher einen Luftstrahl als Trans¬ portmedium verwendet, bevorzugt wird.The solution according to the invention is preferably applied as a spray, application in a pressure bottle being possible, but for environmental reasons a pump mechanism which is customary in cosmetics and which uses an air jet as the transport medium is preferred.
Erfindungsgemäß werden die Schläger einmal gründlich mit der erfindungsgemä¬ ßen Sprayflüssigkeit eingesprüht, wozu 0,5 bis 1 cm3 einer 4-5 %igen Lösung ge¬ nügen und später der im Spiel auftretende Abrieb des Harzes durch Nachsprühen mit 0,1-0,5 ml einer Lösung in den notwendigen Abständen ersetzt.According to the invention, the clubs are thoroughly sprayed once with the spray liquid according to the invention, for which 0.5 to 1 cm 3 of a 4-5% solution are sufficient and later the abrasion of the resin which occurs in the game by spraying with 0.1-0. 5 ml of a solution replaced at the necessary intervals.
Obwohl das Aufsprühen der erfindungsgemäßen Lösungen besonders einfach ggf. auch auf dem Spielfeld durchgeführt werden kann, ist es natürlich auch mög¬ lich, eine entsprechend konzentrierte Lösung mittels eines Pinsels direkt auf die Saiten aufzubringen oder diese vor dem Bespannen des Schlägers in die Lösung zu tauchen und so zu imprägnieren. Da ein gleichmäßiger erster Auftrag dabei das Aufbringen größerer Mengen Kolophonium erfordert, sind Konzentrationen von 5 - 20 % in diesem Fall bevorzugt. Diese Auftragstechnik ist insbesondere beim Vorpräparieren der Schläger sinnvoll, da dabei nicht unnütz Harz an den Saiten "vorbeigesprüht" wird.Although the spraying of the solutions according to the invention can be carried out particularly easily and possibly also on the playing field, it is of course also possible to apply a correspondingly concentrated solution directly to the strings by means of a brush or to dip them into the solution before stringing the racket and so impregnate. Since a uniform first application requires the application of large amounts of rosin, concentrations of 5-20% are preferred in this case. This application technique is particularly useful when preparing the racket, since resin is not "wasted" on the strings.
Ein Zusatz von Fumarsäure und/oder Maleinsäure hat sich dabei als besonders vorteilhaft erwiesen, da nicht nur der Erweichungspunkt des Harzes dadurch er¬ höht wird, was die Oberfläche der beschichteten Saiten trockener (weniger kleb¬ rig) erscheinen läßt, sondern auch die Lösungen konzentrierter, z. B. bis 50 % (g/ml), angesetzt werden können. The addition of fumaric acid and / or maleic acid has proven to be particularly advantageous since not only the softening point of the resin is increased, which makes the surface of the coated strings appear drier (less sticky), but also the solutions are more concentrated , e.g. B. up to 50% (g / ml) can be applied.
