Description

Mittel zum Raumachen und Rauhalten von Schläger-Bespannungen für Tennis, Badminton und Squash sowie Verfahren zu dessen Herstellung Means for making and holding rackets for tennis, badminton and squash, and methods of making the same
[0001] Die vorliegende Erfindung betrifft ein Mittel, um die Bespannung, das heisst die Saiten von Tennisrackets sowie Badminton- und Squash-Schlägem zu behandeln, sodass dieses Saiten eine raue Oberfläche aufweisen. Eine solche raue Oberfläche ist besonders wesentlich für das Ausführen von Schlägen, welche dem Ball einen Drall oder Spin verleihen sollen. Ausserdem betrifft die Erfindung das Verfahren zur Herstellung dieses Mittels.The present invention relates to a means to treat the fabric, that is the strings of tennis rackets and badminton and squash strokes, so that these strings have a rough surface. Such a rough surface is particularly important for making punches which are supposed to impart a spin or spin to the ball. In addition, the invention relates to the process for the preparation of this agent.
[0002] Der Tennissport hat in den letzten Jahren eine rasante Entwicklung durchgemacht, im Rahmen derer die Spieldynamik wie auch die Schnelligkeit des Spiels enorm zugenommen hat. Ähnliches gilt auch für verwandte Spielarten wie Badminton und Squash. Die Tennisrackets sind dabei einer grossen Beanspruchung ausgesetzt. Professionelle Spieler benützen ein Racket bloss für ein einziges Spiel. Die frisch aufgezogenen Saiten einer Tennis-Racket- Bespannung sind nämlich körnig und rau. Sie ermöglichen es, durch das Anschneiden des abzuspielenden Balles demselben einen Drall mitzugeben. Nur mit einer rauen Oberfläche der Bespannung kann eine Kraftkomponente auf den Ball übertragen werden, die etwa quer zur Flugbahn wirkt und längs der Bespannung verläuft. Die Rauheit einer Racket-Bespannung lässt jedoch durch die Abnützung der Saiten rasch nach. Je öfter mit Drall gespielt wird, was bei fortgeschrittenen Spielern häufiger der Fall ist, umso rascher werden die Saiten glatt und damit für ein entsprechend anspruchsvolles Spiel stumpf. Während die Profispieler deshalb für jeden Match auf ein frisch gespanntes Racket zurückgreifen, ist das den vielen Amateur- und Hobbyspielem zu aufwändig und zu teuer. Trotzdem besteht natürlich auch bei den Amateurspielern der Wunsch, über ein optimales Racket zu verfügen. Mit einem neuen Tennisracket lässt sich nachweisbar um eine Kategorie besser spielen als mit einem Racket mit ermüdeter und stumpfer Bespannung. Das Gleiche gilt auch für die Schläger zum Spielen von Badminton und Squash.The tennis has undergone rapid development in recent years, in the context of which the game dynamics as well as the speed of the game has increased enormously. The same applies to related games such as badminton and squash. The tennis rackets are exposed to great stress. Professional players only use a racket for a single game. The freshly wound strings of a tennis racquet string are grainy and rough. They make it possible to impart a spin by cutting the ball to be played. Only with a rough surface of the clothing, a force component can be transmitted to the ball, which acts approximately transversely to the trajectory and along the Covering runs. The roughness of a racquet string, however, decreases quickly due to the wear of the strings. The more you play with spin, which is more common in advanced players, the faster the strings become smooth and dull for a suitably challenging game. While the professional players therefore resort to a freshly stretched racket for each match, this is too time-consuming and too expensive for the many amateur and amateur games. Nevertheless, of course, there is also a desire among amateur players to have an optimal racquet. With a new tennis racket you can demonstrably play around a category better than with a racket with tired and blunt clothing. The same goes for the rackets for playing badminton and squash.
[0003] Es ist deshalb die Aufgabe dieser Erfindung, ein Mittel zum Raumachen und Rauhalten von Schläger-Bespannungen für Tennis, Badminton und Squash anzugeben, wobei dieses Mittel einfach und sicher anzuwenden sein soll und die Saiten der Bespannungen über längere Zeitperiode rau halten soll, sodass von einem bestimmten Spieler eine grossere Schlagkraft entfaltet und höhere Spins geschlagen werden können. Die Bespannungen sollen durch dieses Mittel geschont und daher langlebiger werden. Ausserdem ist es eine Aufgabe der Erfindung, das Verfahren zur Herstellung dieses Mittels anzugeben.It is therefore the object of this invention to provide a means for Raumachen and Rauhalten of rackets for tennis, badminton and squash, this means should be easy and safe to use and keep the strings of clothing over a long period of rough, so that a certain player can develop a greater power of impact and higher spins can be beaten. The coverings are to be spared by this means and therefore longer lasting. In addition, it is an object of the invention to provide the process for the preparation of this agent.
[0004] Diese Aufgabe wird gelöst von einem Mittel zum Raumachen und Rauhalten von Schläger-Bespannungen für Tennis, Badminton und Squash bestehend aus wenigstens den beiden Komponenten Saxolith, einem kristallinen Füllstoff auf Marmorbasis, sowie Erkamar, einem Bindemittel mit Hafteigenschaften.This object is achieved by a means for Raumachen and Rauhalten of rackets for tennis, badminton and squash consisting of at least the two components Saxolith, a crystalline filler marble-based, and Erkamar, a binder with adhesive properties.
[0005] Das Verfahren zur Herstellung des Mittels ist dadurch gekennzeichnet, dass Erkamar in mindestens ebensoviel Wasser gemischt und einige Stunden gerührt wird, hernach die Mischung auf Raumtemperatur abgekühlt wird, und dann mindestens gleichviel Saxolith wie vorher Erkamar zugegeben und umgerührt wird, bis eine homogene Mischung erzielt ist. [0006] Im Folgenden wird das Verfahren und das damit erzeugte Mittel anhand von Ausführungsbeispielen offenbart. Als wesentliche Komponenten enthält das Mittel eine körnige Masse, deren Körner scharfkantig sind und eine grosse Härte aufweisen, die sicherstellt, dass diese scharfen Körperkanten auch bei Beanspruchung möglichst lange scharf bleiben. Desweiteren enthält das Mittel einen Haftvermittler, der sicherstellt, dass die Körner in demselben eingebettet und gehalten sind, und dass eine innige und starke Verbindung mit der Oberfläche der Saiten entsteht, welche auch unter Beanspruchung anhält und dauerhaft ist.The process for the preparation of the composition is characterized in that Erkamar is mixed in at least as much water and stirred for a few hours, after which the mixture is cooled to room temperature, and then at least as much saxolite Erkamar as previously added and stirred until a homogeneous Mixture is achieved. In the following, the method and the means thus produced by means of embodiments will be disclosed. As essential components, the agent contains a granular mass whose grains are sharp-edged and have a high hardness, which ensures that these sharp body edges remain sharp as long as possible even under stress. Furthermore, the agent contains an adhesion promoter, which ensures that the grains are embedded and held in the same, and that an intimate and strong connection with the surface of the strings is produced, which also stops under stress and is durable.
[0007] Hierzu hat sich gezeigt, dass sich Saxolith als vorteilhaftes Mittel zur Beschaffung und Sicherstellung der Rauheit erweist. Bei Saxolith handelt es sich grundsätzlich um einen kristallinen Calciumcarbonatfüllstoff, der Marmor enthält. Er ist in verschiedenen Typen und Körnungen erhältlich, gemäss folgender Tabelle:For this purpose, it has been shown that saxolite proves to be an advantageous means for obtaining and ensuring the roughness. Saxolith is basically a crystalline calcium carbonate filler containing marble. It is available in different types and grits, according to the following table:
[0008] Grundsätzlich eignet sich jeder dieser Typen zur Erzielung der gewünschten Rauheit. Durch Zusammenmischung verschiedener Typen lässt sich sogar eine gezielte Mischung herstellen, wobei nicht überraschend gilt, dass, je rauer die Saitenoberflächen werden, umso weniger dauerhaft deren Rauheit ist.In principle, each of these types is suitable for achieving the desired roughness. By blending different types, you can even create a specific mix, and it's not surprising that the rougher the string surfaces are, the less durable their roughness is.
[0009] Zum Aufbringen dieses Saxoliths auf die Saiten einer Bespannung muss der Saxolith in einen Haftvermittler eingebracht werden, zum Beispiel in Form einer viskosen Flüssigkeit oder einer pastösen Masse, die hernach auf die Saiten aufgebracht werden kann und die eine starke Haftverbindung mit der Saitenoberfläche sicherstellt. Als vorteilhaftes Bindemittel mit Hafteigenschaften erweist sich Erkamar. Dabei handelt es sich um einen Haftvermittler in Form eines Harzes, genauer um einen höherschmelzenden Dispergierharz mit Pigmentbelegung, der in Alkohol und nach Neutralisation auch in Wasser löslich ist.To apply this saxolite to the strings of a stringing the saxolite must be introduced into a primer, for example in the form of a viscous liquid or a pasty mass, which can be applied afterwards to the strings and ensures a strong adhesive bond with the string surface , As an advantageous binder with adhesive properties Erkamar proves. This is an adhesion promoter in the form of a resin, more precisely a higher-melting dispersing resin Pigment occupancy, which is soluble in alcohol and after neutralization in water.
[0010] Um das Mittel zum Raumachen und Rauhalten der Saiten herzustellen, wird wie folgt vorgegangen: Zunächst wird Erkamar in mindestens ebensoviel Wasser gemischt und einige Stunden gerührt. Man nimmt ca. 2 Teile Erkamar und mischt es mit ca. 3 Teilen Wasser. Dann wird die Mischung während einiger Stunden gerührt, mindestens während vier Stunden. Die Mischung erwärmt sich dabei. Sobald eine homogene Mischung erzielt ist, lässt man sie auf Raumtemperatur abkühlen. Erst dann erfolgt das Untermischen von Saxolith, mindestens wiederum 2 Teile, vorzugsweise jedoch ca. 2.5 Teile. Dann wird erneut gerührt, bis eine homogene Mischung des Saxolith mit dem flüssigen Haftvermittler erzielt ist. Danach liegt das Mittel in Form eines flüssigen, weisslich bis ockerfarbigen Antirutschlacks vor und ist bereit zum Auftrag auf die Saiten einer Schlägerbespannung. Das Auftragen kann ganz einfach mit einem Pinsel erfolgen, bis alle Saitenoberflächen vom Mittel bedeckt und umschlossen sind. Hernach lässt man den Anstrich völlig austrocknen. Im Umgang mit diesem wässrigen Anstrichmittel bzw. -lack sollten die üblichen Massnahmen beim Umgang mit Chemikalien beachtet werden. Als Vorsichtsmassnahmen sollen Schutzhandschuhe getragen werden und eine Schutzbrille oder ein Gesichtsschutz sollte getragen werden. Ein Atemschutz ist allerdings nicht nötig. Dieser Anti rutsch lack sollte nicht unter 00C gelagert werden.To produce the means for Raumachen and Rauhalten the strings, proceed as follows: First Erkamar is mixed in at least as much water and stirred for several hours. Take about 2 parts Erkamar and mix it with about 3 parts of water. Then the mixture is stirred for a few hours, at least for four hours. The mixture heats up. Once a homogeneous mixture is achieved, allow to cool to room temperature. Only then does the intermixing of saxolite, at least in turn 2 parts, but preferably about 2.5 parts. Then it is stirred again until a homogeneous mixture of the saxolite is achieved with the liquid bonding agent. Thereafter, the agent is in the form of a liquid, whitish to ocher anti-slip and is ready to order on the strings of a racket. The application can be easily done with a brush until all the string surfaces are covered and enclosed by the medium. Afterwards, the paint is allowed to dry completely. When handling this aqueous paint or varnish, the usual measures should be observed when handling chemicals. Protective gloves should be worn as precautionary measures and goggles or face shield should be worn. A respiratory protection is not necessary. This anti-slip varnish should not be stored under 0 0 C.

[0012] Soll eine Menge von 100kg Anti rutsch lack mit diesen Komponenten hergestellt werden, so kommt folgendes Verfahren zur Anwendung: Zunächst wird eine Mischung aus folgenden Komponenten angesetzt:If an amount of 100kg anti-slip paint with these components are prepared, the following method is used: First, a mixture of the following components is used:
30.4 kg Wasser30.4 kg of water
8.1 kg Dimethylethanolamin 6 kg Isopropanol8.1 kg of dimethylethanolamine 6 kg of isopropanol
22.5 kg Erkamar 3280 Diese 69.5 kg-Mischung wird nun während 5 bis 6 Stunden maschinell umgerührt, bis eine schön homogene Mischung erzielt ist. Während des Umrührens erwärmt sich die Mischung, weswegen sie nach dem Umrühren für etwa 24 Stunden stehengelassen wird, damit sie wieder auf Raumtemperatur abkühlt.22.5 kg Erkamar 3280 This 69.5 kg mixture is then stirred mechanically for 5 to 6 hours until a nicely homogenous mixture is achieved. While stirring, the mixture heats up and, after stirring, it is allowed to stand for about 24 hours to cool back to room temperature.
[0013] Hernach, das heisst meistens am Folgetag, wird 27 kg Saxolith 5 HE und 5kg Sipernat 820AG zugegeben, sowie ca. 0.6kg Agitan E 120 und ca. 0.6kg Byk 420. Diese ganze Mischung wird dann weiter ca. 4 bis 5 Stunden umgerührt, was zur innigen Vermischung führt, sodass ein flüssiger, weisslicher bis ockerfarbiger, gut streichfähiger Anti rutsch lacks erhalten wird.Afterwards, that is usually the following day, 27 kg Saxolith 5 HE and 5kg Sipernat 820AG is added, as well as about 0.6kg Agitan E 120 and about 0.6kg Byk 420. This whole mixture will continue about 4 to 5 Stirred for hours, which leads to the intimate mixing, so that a liquid, whitish to ocher, well spreadable anti-slip varnish is obtained.
[0014] Die Körnung sowie die Zusammensetzung des Saxolith-Anteils kann im Rahmen ihre Gesamtanteils an der Mischung nach Belieben variiert werden. Dieser Anti rutsch lack kann dann mit einem Pinsel auf die Saiten einer Bespannung gestrichen werden, bis die Saiten allseits von ihm eingehüllt sind und somit ummantelt sind. Dann lässt man den Anstrich trocknen und richtig aushärten, was am besten über Nacht erfolgt. Anderntags ist das Racket bzw. der Badminton- oder Squash-Schläger spielbereit. Durch den Anstrich sind die Saitenoberflächen rau und bleiben für viele Stunden Spielzeit rau. Wenn diese Beschichtung der Saiten schliesslich abgenützt ist, so kann die Spannung einfach von neuem bestrichen werden. Man bestreicht dann nur jene Stellen der Bespannung, die abgenützt sind, also vorwiegend den Bereich um das Zentrum der Bespannung, und das kann wenn nötig viele Male wiederholt werden, bis die Saiten ohnhin ihre Spannkraft verloren haben und die Bespannung oder gar das ganze Racket ersetzt werden muss.The grain size and the composition of the saxolite content can be varied as desired within the scope of their total content of the mixture. This anti-slip varnish can then be brushed onto the strings of a string with a brush until the strings are wrapped around it on all sides and are therefore covered. Then let the paint dry and cure properly, which is best done overnight. The next day the racquet or the badminton or squash racket is ready to play. By painting the string surfaces are rough and remain rough for many hours of play. If those Finally, the coating of the strings is worn, so the tension can be easily repainted. You then only spreads those parts of the clothing that are worn out, ie predominantly the area around the center of the clothing, and this can be repeated many times if necessary, until the strings have lost their elasticity and replaced the clothing or even the whole racket anyway must become.
[0015] Mit diesem Antirutschlack behandelte Rackets erhöhen die Schlagkraft und den Spin bei einem bestimmten Spieler oder einer bestimmten Spielerin schlagartig, egal ob er/sie ATP-/WTA-Spieler(in) ist oder ein Club- oder Freizeitspieler(in). Ausserdem ist als positiver Nebeneffekt zu vermerken, dass Haltbarkeit der Bespannung deutlich verlängert wird. Die Saiten werden nämlich durch den Anstrich von Feuchtigkeit geschützt und beim Spielen geschont. Gebrauchte Saiten bzw. alte Bespannungen lassen sich durch die Beschichtung in ihrer Spannkraft und ihrer Spielwirksamkeit wesentlich verbessern. [0015] Rackets treated with this anti-slag abruptly increase the power and spin of a particular player or player, whether he / she is an ATP / WTA player or a club or recreational player. In addition, it should be noted as a positive side effect that durability of the fabric is significantly extended. The strings are protected by the coating of moisture and spared while playing. Used strings or old clothing can be significantly improved by the coating in their resilience and their game effectiveness.
