BeschreibunR: Tischtennisschläger mit gelochter SchlägerplatteDescription: Table tennis racket with a perforated racket plate
Zur Vereinfachung werden die Grundplatte und die Beläge des Tischtennisschlägers gemeinsam als achlägerplatte bezeichnet.To simplify matters, the base plate and the coverings of the table tennis racket are used collectively referred to as a racket plate.
Derzeit werden Tischtennisschläger mit geschlossener Schlägerplatte verwendet,wobei die oberfläche entweder plan ausgeführt ist oder Noppen trägt.Table tennis rackets with a closed racket plate are currently being used used, whereby the surface is either flat or has knobs.
Diese Art Schläger weisen bei horizontal gefLihrten,schnellen Schlägen folgenden Nachteil auf: i3eim Vorwärtsbewegen des Tischtennisschlägers wird die Luft vor der Schlägerplatte verdichtet und strömt,bedingt durch deren Stellung,meist ungleichmässig über die K;i.nte der achlägerplatte ab.This type of racket is useful for horizontally guided, fast strokes has the following disadvantage: When moving the table tennis racket forward, the Air in front of the racket plate compresses and flows, depending on its position, mostly unevenly over the edge of the racket plate.
Der Tischtennisball erfährt beim Durchdringen dieser verdichteten Luft vor dem Auftreffen auf die Schlägerplatte Ver-Snderungen seiner Bewegungsparameter (z.B.der Flugrichtung, der Geschwindigkeit),woraus eine Beeinträchtigung der Schlaggenauigkeit resultiert.The ping pong ball is compressed when it penetrates it Air before hitting the racket plate changes its movement parameters (e.g. the direction of flight, the speed), from which an impairment of the shot accuracy results.
Aufgabe der Erfindung ist es,eine achlagerplatte zu entwickeln, die die Bewegungsparameter des Tischtennisballes so wenig wie möglich verändert.The object of the invention is to develop a bearing plate that changes the movement parameters of the table tennis ball as little as possible.
Gegenstand der Erfindung ist ein Tischtennisschläger,der von der Vorderseite zur Rückseite der Schlägerplatte durchgehende Gffnungen besitzt.The invention is a table tennis racket from the front has continuous openings to the rear of the racket plate.
Prinzip: Durch die durchgehenden Öffnungen der Schlägerplatte wird beim Vorwärtsbewegen des Schlagers und Schlagen des Tischtennisballes die vor dem schläger befindliche Luft erheblich weniger verdichtet.Dadurch werden Veränderungen der Flugparameter (z.B.der Flugrichtung,der Geschwindigkeit) des Tischtennisballes durch Luftstau weitestgehend vermieden und eine erheblich höhere Schlaggenauigkeit erzielt.Principle: Through the through openings of the racket plate when moving the striker forward and hitting the table tennis ball before The air in the racket is much less compressed, causing changes the flight parameters (e.g. the flight direction, the speed) of the table tennis ball largely avoided by air congestion and a significantly higher impact accuracy achieved.
Die durchgehenden Offnungen der Schlägerplatte sind in ihrer Form in den Grundmodellen A und B kreisförmig,können jedoch auch andere Formen haben wie z.B.Ovale,Schlitze,Kechtecke, Quadrate.The through openings of the racket plate are in their shape circular in the basic models A and B, but can also have other shapes such as oval, slits, rectangles, squares.
Der Durchmesser der kreisförmigen Öffnungen der Schlägerplatte kann maximal bis zu 7 mm betragen,wobei das Grundmodell A mit 416 Öffnungen von 5 mm Durchmesser und das Grundmodell B mit 1150 Offnungeon 3 mm Durchmesser ausgestattet ist.Dadurch beträgt der luftdurchlässige Teil der Schlägerplatte ca. 40% der Gesamtfläche.The diameter of the circular openings of the racket plate can be maximum up to 7 mm, whereby the basic model A with 416 openings of 5 mm Diameter and the basic model B with 1150 openings of 3 mm diameter This means that the air-permeable part of the racket plate is approx. 40% of the total area.
Je nach gewünschter Verbesserung der Schlaggenauigkeit können die Größe,die Form,die Anzahl und die Anordnung der durchgehenden Öffnungen variiert werden.Depending on the desired improvement in impact accuracy, the The size, shape, number and arrangement of the through openings vary will.
Das Prinzip der gelochten Schlägerplatte ist auf alle Größen der Schlägerplatte von Tischtennisschlägern anwendbar.The principle of the perforated racket plate is applicable to all sizes of the racket plate of table tennis bats applicable.
Durch Variationen in der Anordnung und die Benutzung von verschiedene rößen und Formen der durchgehenden Cffnungen auch auf einer Schlägerplatte lassen sich diese in einer Vielzahl von Modellen mit ähnlichem Effekt herstellen.Through variations in the arrangement and the use of different ones The sizes and shapes of the through openings can also be left on a racket these can be produced in a variety of models with a similar effect.
