Abstract

A racket for ball games and more specifically, a tennis racket, has a frame forming a racket head, a shank and a grip secured to the shank with a force fit so that the grip may be turned in relation to the racket head into different settings. The force fit connecting elements are simple to manufacture, yet permit an exact stepless setting and a satisfactory transmission of the forces produced while still avoiding a slip clutch effect. The grip and the racket shank are joined with each other by a surface area of substantial size which assures the required frictional engagement for the force fit in the angular direction while providing a form locking connection in the axial direction. The shank is part of an integral, one-piece handle bar which also has a cylindrical section and a conical section integrally interconnecting the shank to the cylindrical section.

Description

Die Erfindung betrifft einen Schläger für ein Ballspiel, insbesondere einen Tennisschläger mit einem aus Schlägerkopf, Schaft und Griff bestehenden Rahmen, dessen Griff relativ zum Schlägerkopf verstellbar ist.The invention relates to a racket for a ball game, in particular a tennis racket with a frame consisting of racket head, shaft and handle, the handle of which is adjustable relative to the racket head.

Ein Tennisschläger der genannten Art ist aus der deutschen Gebrauchsmusterschrift 77 17 463 bekannt. Hier ist der Griff über eine Rastverbindung stufenweise verstellbar, so daß der Schläger mit unterschiedlichen Einstellungen benutzbar ist. Dies ist vor allem zum Üben des Rückhandspieles vorteilhaft. Der bekannte Tennisschläger hat sich aber nicht bewährt, da die Verstellung zeitaufwendig ist und da sie nur stufenweise und somit in fest vorgegebenen Winkeln möglich ist. Ausserdem tritt bei längerem Gebrauch ein Verschleiß im Bereich der Verzahnung ein, wodurch sich die Griffteile lockern. Schließlich ist auch die Herstellung kostenaufwendig.A tennis racket of the type mentioned is known from German utility model 77 17 463. Here the handle is gradually adjustable via a snap connection, so that the racket can be used with different settings. This is particularly useful for practicing backhand play. The well-known tennis racket has not proven itself, however, since the adjustment is time-consuming and because it is only possible in stages and thus at predetermined angles. In addition, wear occurs in the area of the teeth with prolonged use, which loosens the handle parts. Finally, the manufacture is also expensive.

Des weiteren ist aus der US-PS 3 545 755 ein Tennisschläger mit starrem, relativ zur Schlagebene verdrehtem Griff bekannt. Dieser Tennisschläger hat sich aber in der Praxis nicht durchsetzen können.Furthermore, from US Pat. No. 3,545,755 a tennis racket with a rigid handle rotated relative to the playing plane is known. However, this tennis racket was not successful in practice.

Der Erfindung liegt die Aufgabe zugrunde, einen Schläger für ein Ballspiel, insbesondere Tennisschläger zu schaffen, dessen Griff sich relativ zum Schlägerkopf stufenlos verstellen läßt, der kostengünstig hergestellt werden kann und dessen Verstellmechanismus möglichst einfach zu handhaben ist.The invention has for its object to provide a racket for a ball game, in particular tennis racket, the handle can be adjusted continuously relative to the racket head, which can be manufactured inexpensively and the adjustment mechanism is as easy to use as possible.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß der Griff und der Schlägerkopf bezüglich ihrer Winkeleinstellung relativ zueinander kraftschlüssig miteinander verbindbar sind.To achieve this object, the invention provides that the handle and the club head can be non-positively connected with respect to one another with respect to their angle setting.

Die kraftschlüssige Verbindung erlaubt eine stufenlose Feineinstellung des relativ zum Schlägerkopf verdrehbaren Griffes. Sie ist darüber hinaus einfach und kostengünstig herzustellen, weil nur glatte Berührungsflächen benötigt werden.The non-positive connection allows the fine adjustment of the handle, which can be rotated relative to the club head. It is also easy and inexpensive to manufacture because only smooth contact surfaces are required.

Vorzugsweise sind am Schaft des Schlägers ein Konus und am Griff eine konische Bohrung bzw. ein Innenkonus angeordnet. Sie gestatten sowohl eine gute Übertragung der im Schlägerschaft bzw. Griff auftretenden Querkräfte als auch in gelockertem Zustand eine stufenlose Feineinstellung des Schlägerkopfes relativ zum Griff.A cone is preferably arranged on the shaft of the racket and a conical bore or an inner cone is arranged on the handle. They allow both a good transmission of the transverse forces occurring in the club shaft or handle and, in the relaxed state, a continuous fine adjustment of the club head relative to the handle.

Weitere Merkmale der Erfindung gehen aus der Beschreibung und den Ansprüchen im Zusammenhang mit der Zeichnung hervor.Further features of the invention emerge from the description and the claims in connection with the drawing.

Die Erfindung wird nachstehend anhand von Ausführungsbeispielen, die in der Zeichnung dargestellt sind, näher beschrieben. Dabei zeigen:

  • Fig. 1: einen Tennisschläger mit einem stufenlos verstellbaren Griff;
  • Fig. 2: einen Schnitt durch den Griff mit einem Teil des Schaftes in größerem Maßstab und
  • Fig. 3: einen Schnitt durch eine abgewandelte Ausführungsform.
The invention is described below with reference to exemplary embodiments which are shown in the drawing. Show:
  • Fig. 1: a tennis racket with a continuously adjustable handle;
  • Fig. 2: a section through the handle with part of the shaft on a larger scale and
  • 3: a section through a modified embodiment.

Ein erfindungsgemäßer Tennisschläger 1 besteht aus einem Rahmen 2 mit einem Griff 3, einem Schaft 4 und einem Schlägerkopf 5 mit Besaitung 6. Der Griff 3 ist relativ zum Schlägerkopf 5 um die Schlägerlängsachse 7 stufenlos verdrehbar und in jeder Stellung befestigbar. Bezüglich ihrer Winkeleinstellung und somit zur Aufnahme der Dreh- oder Torsionskräfte sind der Griff 3 und der Schlägerkopf 5 kraftschlüssig miteinander verbunden.A tennis racket 1 according to the invention consists of a frame 2 with a handle 3, a shaft 4 and a racket head 5 with strings 6. The handle 3 can be rotated continuously relative to the racket head 5 about the longitudinal axis 7 of the racket and can be fastened in any position. With regard to their angle setting and thus to absorb the torsional or torsional forces, the handle 3 and the racket head 5 are non-positively connected to one another.

Hierzu sind kegelförmige bzw. kegelstumpfförmige Flächen 8 und 9 zwischen dem Griff 3 und dem Schlägerkopf 5 vorgesehen. Zur Bildung dieser Flächen dienen ein Konus 1o am Schaft 4 und eine konische Bohrung 11 bzw. ein Innenkonus 11 am Griff 3.For this purpose, conical or frustoconical surfaces 8 and 9 are provided between the handle 3 and the club head 5. A cone 10 on the shaft 4 and a conical bore 11 or an inner cone 11 on the handle 3 serve to form these surfaces.

An dem Konus 1o des Schaftes 4 ist ferner ein Gewindebolzen 12 angeordnet, zu dem am Griff 3 ein Griffstück 13 mit einem Innengewinde 14 gehört.A threaded bolt 12 is also arranged on the cone 10 of the shaft 4, to which a grip piece 13 with an internal thread 14 belongs on the handle 3.

Der Griff 3 ist im wesentlichen hülsenförmig und übergreift mit seinem Innenkonus 11 den Konus 1o am Schaft 4 und nimmt mit einer Bohrung 15 den Gewindebolzen 12 auf. Mit Hilfe des auf den Gewindebolzen 12 nach Art einer Mutter aufschraubbaren Griffstückes 13 ist der Griff 3 am Schaft 4 befestigt, wobei dies nach Verdrehen von Griff 3 und Schaft 4 in jeder beliebigen Position möglich ist.The handle 3 is essentially sleeve-shaped and overlaps the cone 10 with its inner cone 11 Shaft 4 and receives the threaded bolt 12 with a bore 15. With the aid of the handle 13, which can be screwed onto the threaded bolt 12 in the manner of a nut, the handle 3 is fastened to the shaft 4, this being possible in any position after turning the handle 3 and shaft 4.

Das Griffstück 13 ist bei den in den Figuren dargestellten Ausführungsbeispielen am Griffende 16 angeordnet und stützt sich in Richtung der Schlägerlängsachse 7 auf diesem ab. An seinem Umfang ist das Griffstück 13 profiliert.In the exemplary embodiments shown in the figures, the grip piece 13 is arranged at the grip end 16 and is supported on the longitudinal axis 7 of the stick in the direction of the latter. The handle 13 is profiled on its circumference.

Die Fig. 3 zeigt eine abgewandelte Ausführungsform, gemäß der ein ebenfalls ein Innengewinde 17 für den Gewindebolzen 12 aufweisendes Griffstück 18 vorgesehen ist, das mit einem hülsenförmigen Teil 19 in die Bohrung 15 des Griffes 3 greift. Das hülsenförmige Teil 19 weist eine Ringnut 2o auf, in die sich mindestens ein mit dem Griff 3 verbundenes Halteelement 21 erstreckt. Das Halteelement 21 ist beispielsweise durch die Wand 22 des Griffes 3 geschraubt und dient als Widerlager beim Drehen bzw. Lösen und Festziehen des Griffstückes 18. Die Teile 2o und 21 bilden eine Kulissenführung.3 shows a modified embodiment, according to which a handle 18, which also has an internal thread 17 for the threaded bolt 12, is provided, which engages with a sleeve-shaped part 19 in the bore 15 of the handle 3. The sleeve-shaped part 19 has an annular groove 20, into which at least one holding element 21 connected to the handle 3 extends. The holding element 21 is, for example, screwed through the wall 22 of the handle 3 and serves as an abutment when turning or loosening and tightening the handle piece 18. The parts 2o and 21 form a link guide.

Hinsichtlich Form und Gestalt werden die konischen Teile und der Gewindebolzen entsprechend den auftretenden Kräften dimensioniert. Als Werkstoff dient zweckmäßigerweise ein Kunststoff, wobei wegen der Reibungskoeffiziaten unterschiedliche Werkstoffe für den Konus 1o und die Oberfläche der konischen Bohrung 11 vorteilhaft sind.With regard to shape and shape, the conical parts and the threaded bolts are dimensioned according to the forces that occur. A plastic is expediently used as the material, different materials for the cone 10 and the surface of the conical bore 11 being advantageous because of the coefficients of friction.
