Description

Tennisschläger Für Tennisschläger ist ,außer der üblichen Herstellung aus Holz eine ganze Reihe von Herstellungsarten aus ,anderen Stioffien bekanntgeworden, so aus Papiermachh, Kunstharzen und ähnlichen Stoffen. Da derartige Schläger zu schwer und dabei noch Glicht einmal fest genug wurden, hat man anderseits Stahlrohr oder ähnlichen hohlen Baustoff zum Rahmen gebogen und in einem Griffee hefestigt, ioder man hat auch ;einen hohlen Griff und seinen vollen Rahmen je für sich hergestellt und nlitein.ander vereinigt. Alle diese zusammengesetzten Schläger lassen aber an Festigkeit und insbesondere an Rüttelsicherhleit - viel zu wünschen übrig und habien sich daher nicht einführen können.Tennis racket For tennis rackets is, in addition to the usual manufacture a whole range of manufacturing methods from wood, other fabrics become known, made of paper mache, synthetic resins and similar materials. Because such rackets too Heavy and, at the same time, Glicht once become firm enough, on the other hand you have tubular steel or similar hollow building material bent to a frame and fastened in a handle, or one has also made a hollow handle and its full frame for itself and united together. However, all these composite clubs leave on Strength and in particular on vibration protection - much to be desired and habien therefore cannot introduce themselves.

Das Wesen der Erfindung besteht darin, daß ein Tennisschläger mit durchweg hohlem Querschnitt in einstückiger Herstellung von Griff und Rahmen aus Hartgummi hergestellt ist. Diese Herstellungsart erlaubt, den Schläger in der für Gummi üblichen Weise im unvulkanisierben Zustand als Hohlkörpler herzustellen, der überall genau die gewünschten Wandstärken erhält und der dann durch Vulkanisieren zu einem unlösbar einheitlichen Körper- zusammengeschlossen wird. Der Erfolg ist im Gegensatz zu allen mehrteiligen Schlägern eine restlose dauernde Rüttelsicherheit und völlig gleichförmige Elastizität bei zugleich ganz besonders gut abstimmbarem Gewicht, weil eben die Wandstärken beliebig genau auf jedes gewünschte Maß gebracht werden können. Die neuen Schläger sind ,an Feuchtigkeitsfestigkeit nicht nur den hölzernen, sondern ,auch allen etwa aus Preßmassen zusammiengeklebten Schlägern überlegen, weil sie restlos feuchtigkeitsunempfindlich sind, natürlich abgesehen von der Beanspruchung durch die Darmsaiten, die in üblichier Weisse bequem auswechselbar sind.The essence of the invention is that a tennis racket with consistently hollow cross-section in one-piece manufacture of handle and frame Hard rubber is made. This production method allows the racket in the for The usual way to produce rubber in the unvulcanized state as a hollow body Everywhere exactly the desired wall thickness is obtained and then through vulcanization is united to an indissolubly unified body. The success is In contrast to all multi-part clubs, it is completely and permanently vibration-proof and completely uniform elasticity while at the same time being particularly easy to tune Weight, because the wall thicknesses are brought to any desired size with any precision can be. The new rackets aren't just that, in terms of moisture resistance wooden, but also all clubs glued together from molding compounds superior because they are completely insensitive to moisture, of course apart from the stress of the gut strings, which can be easily exchanged in the usual white are.

Die Herstellung des neuen Schlagers @erfolgt durch Pressen in Formten. Die Wandstärken sind so bemessen, daß neben richtigem Gesamtgewicht auch richtige Verteilung .der Massen um die neutrale Achsre und ge- eignete Massenwirkung des Schlägers :erreicht wird. Erwünschtenfalls könnten Verstärkungsrippen innen oder ,außen angebracht sein, und ,auch die Einlagerung von Einlagen aus Metall ioder sonstigen Stoffen kann in der für Gummi üblichen Art erfolgen.The production of the new hit @ is done by pressing in molds. The wall thicknesses are such that in addition to correct total weight and proper distribution .the masses about the neutral Achsre and overall suitable mass action of the club: is achieved. If desired, reinforcing ribs could be attached inside or outside, and the inclusion of inserts made of metal or other materials can be done in the manner customary for rubber.
