Abstract
Description
Die Erfindung betrifft einen Tischtennisschläger mit einem flächigen, an einem Griff befestigten Schlägerblatt, das aus einer ein- oder mehrschichtig ausgebildeten Holzseele und ein- oder beidseitig auf die Seele aufgeklebten Belägen aus Kunststoff, Kautschuk, Gummi oder dergleichen besteht.The invention relates to a table tennis racket with a flat, attached to a handle racquet blade, which consists of a single or multi-layered wooden core and one or both sides glued to the soul coverings of plastic, rubber, rubber or the like.
Bei den bekannten Tischtennisschlägern ist es zur optimalen Kontrolle des vom Schläger getroffenen und abspringenden Balls erforderlich, den Ball möglichst im Bereich des Schlägerschwerpunktes, des sogenannten „sweet spot's” zu treffen. Bei seitlich auf die Schlägerfläche auftretenden Bällen springen diese häufig nicht in der vom Spieler gewünschten Richtung ab und werden daher leicht verschlagen.In the known table tennis rackets, it is necessary for optimum control of the hit and dropped by the racket ball to hit the ball as possible in the area of the club's center of gravity, the so-called "sweet spot". With balls occurring laterally on the club surface, these often do not jump in the direction desired by the player and are therefore easily lost.
Die Ursache für dieses Verhalten des Schlägers liegt im Auftreten von Schwingungen mit unterschiedlicher Frequenz und Amplitude sowie in der Ausprägung verschiedener Schub- und Normalspannungszustände, die nach dem Auftreffen des Balles kurzzeitig auftreten und mit wachsender Entfernung vom „sweet spot”, die gewünschte Kontrolle des Balles erschweren.The reason for this behavior of the racket is the occurrence of oscillations with different frequency and amplitude and in the expression of various shear and normal stress states that occur briefly after the impact of the ball and with increasing distance from the "sweet spot", the desired control of the ball difficult.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Tischtennisschläger zu schaffen, mit dem das Absprungverhalten des Balles vom Spieler besser kontrollierbar ist.The invention is therefore an object of the invention to provide a table tennis racket, with the bounce of the ball is better controlled by the player.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Seele mindestens eine flächige Drahtgewebeeinlage aus Kupfer oder einer Kupferlegierung aufweist.According to the invention, this object is achieved in that the core has at least one flat wire mesh insert of copper or a copper alloy.
Erstaunlicherweise scheint das ein- oder beidseitig auf das Holz der Seele bzw. auf oder zwischen dessen furnierartige Lagen aufgeklebte Kupfergewebe in der Lage zu sein, die durch den Aufprall des Balles hervorgerufenen Schwingungen und Spannungen in der gesamten Schlägerfläche zu vergleichmäßigen, so daß sich der Spieler auf das Schlägerverhalten besser einstellen kann, auch wenn der Ball in größerem Abstand vom „sweet spot” auftrifft.Surprisingly, the one or both sides of the wood of the soul or on or between the veneer-like layers glued copper fabric seems to be able to equalize the vibrations and stresses caused by the impact of the ball in the entire club surface, so that the player can adjust better to the club behavior, even if the ball hits at a greater distance from the "sweet spot".
Dazu trägt offensichtlich die vergleichsweise hohe Massenträgheit des schweren Kupfers, seine gute Verformbarkeit aufgrund seiner kubisch-flächenzentrierten Kristallstruktur und andererseits seine Zähigkeit bei. Kupfer weist darüber hinaus auf Grund seiner Stellung in der elektrochemischen Spannungsreihe praktisch keine Oxidationsneigung auf.The relatively high mass inertia of the heavy copper, its good deformability due to its cubic-face-centered crystal structure, and its toughness, obviously contribute to this. Moreover, due to its position in the electrochemical series, copper has virtually no tendency to oxidize.
Versuche mit leichteren und extrem Sauerstoff affinen Aluminiumgewebe führten nicht zu spürbaren Verbesserungen.Experiments with lighter and extremely oxygen affine aluminum fabrics did not lead to noticeable improvements.
Neben Kupfer können auch Kupferlegierungen wie Messing oder Bronze mit annehmbaren Ergebnissen eingesetzt werden.In addition to copper, copper alloys such as brass or bronze can be used with acceptable results.
Die Kupferdrahtgewebeeinlage wird vorzugsweise symmetrisch zur Mittelebene des Schlägerblattes beidseitig eingeklebt. Dadurch wird ein annähernd gleiches, gut kontrollierbares Absprungverhalten des Balles sowohl in der Vorhand- wie auch der Rückhandposition des Schlägers erreicht.The copper wire mesh insert is preferably glued symmetrically to the center plane of the racquet blade on both sides. As a result, an approximately equal, easily controlled bounce of the ball is achieved both in the forehand and the backhand position of the racket.
Bei der Herstellung des erfindungsgemäßen Tischtennisschlägers wird das zum Einsatz vorgesehene Drahtgewebe vorzugsweise so ausgeschnitten, daß es die gesamte Fläche der Seele, also auch den Griffbereich überdeckt. Die beiden Griffschalen werden wie üblich auf die äußeren Schichten der Seele aufgeleimt.In the production of the table tennis racket according to the invention, the wire mesh provided for use is preferably cut out so that it covers the entire surface of the soul, including the handle area. The two handles are glued as usual on the outer layers of the soul.
Neben einem gewebten Drahtgeflecht, das mit Schuss- und Kettfaden auf den üblichen Drahtwebmaschinen hergestellt wird, kann als Drahtgewebe auch ein sogenanntes Gestrick eingesetzt werden. Diese aus lockeren Maschen bestehenden Gewebe weisen in diagonaler Maschenrichtung gegen angreifende Normalkräfte einen höheren Verformungswiderstand auf und können somit einfacher auf die Schlägergröße ausgeschnitten und aufgeklebt werden.In addition to a woven wire mesh, which is produced with weft and warp thread on the usual wire looms, can be used as a wire mesh and a so-called knitted fabric. These loosely meshed fabrics have a higher resistance to deformation in the diagonal mesh direction against attacking normal forces and thus can be more easily cut and adhered to the racket size.
Der Durchmesser des Drahtes der Kupfergewebe liegt vorzugsweise zwischen 0,05 und 0,4 mm, wobei die Maschenfläche zwischen 1 und 8 mm2 groß sein kann.The diameter of the wire of the copper mesh is preferably between 0.05 and 0.4 mm, the mesh area between 1 and 8 mm 2 may be large.
Zur Herstellung der Gewebe kann auch der preiswerte lackierte Kupferdraht verwendet werden, der in großen Mengen für die Wicklungen kleiner Elektromotoren oder Transformatoren produziert wird.For the production of the fabric, it is also possible to use the inexpensive lacquered copper wire which is produced in large quantities for the windings of small electric motors or transformers.
Darüber hinaus ist es auch möglich, insbesondere für gestrickte Gewebe, Flachdraht zu verwenden.Moreover, it is also possible to use flat wire, in particular for knitted fabrics.
Das Gesamtgewicht der Drahteinlagen eines Schlägers sollte 12 g nicht übersteigen, um die ausdauernde Handhabung durch den Spieler nicht zu beeinträchtigen.The total weight of a racket's wire inlays should not exceed 12g, so as not to interfere with player perseverance.
Zum Aufkleben des Drahtgewebes kann ein handelsüblicher Ein- oder Zweikomponentenkleber auf Kunststoffbasis verwendet werden.To stick the wire mesh, a commercially available one or two-component adhesive based on plastic can be used.
Die Erfindung ist in der Zeichnungsfigur beispielsweise veranschaulicht und wird anhand der Zeichnung im Einzelnen erläutert.The invention is illustrated in the drawing figure, for example, and will be explained in detail with reference to the drawing.
Die Zeichnungsfigur zeigt einen Schnitt durch die Schlägerfläche eines Tischtennisschlägers quer zur Schlägerebene.The drawing figure shows a section through the bat surface of a table tennis racket across the racket level.
