Description

Die vorliegende Erfindung bezieht sich auf einen Ballschläger, insbesondere Tennisschläger, gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a ball racket, in particular tennis racket, according to the preamble of claim 1.

Ein derartiger Ballschläger ist aus der DE-OS 20 30 998 bekannt. Dort besteht der Schaft nach einer Ausführungsvariante aus mehreren, entgegen der Kraft von Druckfedern teleskopartig ineinander verschiebbaren Hülsen. Von diesen Hülsen kann die endseitige Hülse als Schlägergriff ausgebildet sein. Hierdurch soll erreicht werden, daß sich der Schaft des Schlägers nach Lösen einer Arretierung plötzlich verlängert, damit der Spieler auch noch einen sonst nicht mehr erreichbaren Ball richtig schlagen kann. Aus diesem Grund sind die Hülsen in wenigstens einer Stellung arretierbar. Zuzüglich können die einzelnen Hülsen gegen solche mit anderem Gewicht oder unterschiedlicher Länge ausgetauscht werden.Such a ball racket is known from DE-OS 20 30 998. There, according to one embodiment variant, the shaft consists of a plurality of sleeves which can be telescoped into one another counter to the force of compression springs. Of these sleeves, the end sleeve can be designed as a club handle. This is to ensure that the shaft of the racket suddenly extends after releasing a lock, so that the player can also hit a ball that is otherwise no longer accessible. For this reason, the sleeves can be locked in at least one position. In addition, the individual sleeves can be exchanged for those with a different weight or different lengths.

Mit der vorliegenden Erfindung soll demgegenüber die Aufgabe gelöst werden, einen Ballschläger, insbesondere Tennisschläger, der genannten Art so auszugestalten, .daß die Länge des Schlägergriffes in einfacher Weise an das Können, die Spielweise und/oder die Kraft des Spielers, vorzugsweise auch stufenlos, angepaßt werden kann.In contrast, the present invention is intended to achieve the object of designing a ball racket, in particular tennis racket, of the type mentioned in such a way that the length of the racket grip in a simple manner depends on the skill, the playing style and / or the strength of the player, preferably also continuously. can be adjusted.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Es hat sich herausgestellt, daß für die gewünschte Längenanpassung eine Verstellung der Grifflänge von 2 cm bis 4 cm ausreicht. Durch die Verlängerung wirkt der Ballschläger für den Spieler "schwerer" und durch die Verkürzung "leichter". Durch die Verwendung unterschiedlich vieler und/oder unterschiedlich dicker Einstellscheiben kann dadurch ein "Medium"-Schläger in der Wirkung schwerer oder leichter gemacht werden. Es genügt daher grundsätzlich ein Ballschlägertyp für alle bisher als notwendig erachteten Ballschlägergewichte.It has been found that an adjustment of the handle length of 2 cm to 4 cm is sufficient for the desired length adjustment. The extension makes the ball racket "heavier" for the player and "lighter" due to the shortening. By using differently and / or differently thick shims, a "medium" racket can be made heavier or lighter in effect. One type of ball racket is therefore generally sufficient for all ball racket weights previously considered necessary.

In Weiterbildung der Erfindung kann bei Verwendung kompressibler Einstellscheiben und einer Einstellschraube auch eine stufenlose Verstellung der Länge des Schlägergriffes erzielt werden.In a further development of the invention, the use of compressible adjusting disks and an adjusting screw also enables the length of the club handle to be adjusted continuously.

Weitere vorteilhafte Einzelheiten der Erfindung sind in den Unteransprüchen angegeben und werden nachfolgend anhand der in der Zeichnung veranschaulichten Ausführungsbeispiele beschrieben. Dabei zeigen:

  • Figur 1 eine Seitenansicht eines Schläger-Griffschaftes im Schnitt und
  • Figur 2 eine gleiche Ansicht im Schnitt, wobei die obere Hälfte einen Griffkopf mit kurzem Hülsenansatz und die untere Hälfte einenGriffkopf mit der Grifflänge entsprechendem Hülsenansatz zeigt.
Further advantageous details of the invention are specified in the subclaims and are described below with reference to the exemplary embodiments illustrated in the drawing. Show:
  • Figure 1 is a side view of a club handle shaft in section and
  • Figure 2 is a similar sectional view, the upper half showing a handle head with a short sleeve attachment and the lower half a handle head with the handle length corresponding sleeve attachment.

In beiden Figuren ist mit 1 das Ende eines im Querschnitt unrunden, beispielsweise 4-eckigen oder 8-eckigen Griffschaftes 2 bezeichnet, der sich vorzugsweise aus zwei Halbschalen zusammensetzt und an den ein nicht dargestelltes Ballschlagfeld eines Ballschlägers, insbesondere Tennisschlägers, anschließt.In both figures, 1 denotes the end of a non-circular cross-section, for example a 4-sided or 8-sided handle shaft 2, which is preferably composed of two half-shells and which is followed by a ball racket field (not shown) of a ball racket, in particular a tennis racket.

In Figur 1 sind an der Frontseite 3 des Schaftendes 1 in Achsrichtung des Griffschaftes 2 verlaufende Stifte 4, insbesondere aus Metall oder zähelastischem Kunststoff, befestigt. Diese Stifte 4 ragen etwa 2 cm bis 5 cm aus der Frontseite 3 des Schaftendes 1 heraus. Auf die Stifte 4 ist eine mit einer zentrischen Bohrung 5 versehene Einstellscheibe 6 entweder aus kompaktem, nicht kompressiblem Material, wie Kunststoff, Holz, Metall oder dgl., oder aus kompressiblem, insbesondere volumenkompressiblem Material, wie geschäumtem Kunststoff, Natur-, Kunstgummi oder dgl. aufgefädelt. Die Außenkontur der Einstellscheibe 6 ist derjenigen des Griffschaftes 2 angepaßt. Wie dargestellt, können auch mehrere Einstellscheiben 61, 62, 63, vorzugsweise auch mit unterschiedlicher Scheibendicke, vorgesehen sein.In FIG. 1, pins 4, in particular made of metal or tough elastic plastic, are attached to the front 3 of the shaft end 1 in the axial direction of the handle shaft 2. These pins 4 protrude approximately 2 cm to 5 cm from the front 3 of the shaft end 1. On the pins 4 is provided with a central bore 5 shim 6 either made of compact, non-compressible material, such as plastic, wood, metal or the like, or from compressible, in particular volume-compressible material, such as foamed plastic, natural, synthetic rubber or the like threaded on. The outer contour of the shim 6 is adapted to that of the handle shaft 2. As shown, a plurality of shims 61, 62, 63 can also be provided, preferably also with different sheave thicknesses.

Die Einstellscheibe 6 bzw. Einstellscheiben 61, 62, 63 sind durch einen Griffkopf 7 abgedeckt, der mittels einer Schraube 9 fest mit dem Griffschaft 2 verbunden ist. Je nach Anzahl oder Dicke der verwendeten Einstellscheiben 6 bzw. 61, 62, 63 kann also die Grifflänge variabel eingestellt werden, wodurch eine Anpassung an die Spieleigenschaften, an das Können oder an die Kraft.des Spielers jederzeit möglich ist. Mit 14 ist das den Griffschaft 2 üblicherweise umgebende Griffband bezeichnet.The adjusting disc 6 or adjusting discs 61, 62, 63 are covered by a grip head 7 which is firmly connected to the grip shaft 2 by means of a screw 9. Depending on the number or thickness of the shims 6 or 61, 62, 63 used, the handle length can be variably adjusted, which means that it can be adapted to the playing characteristics, the skill or the strength of the player at any time. The handle band 2, which usually surrounds the handle shaft 2, is designated by 14.

Wie bereits einleitend erwähnt, kann durch die Verlängerung des Griffschaftes der Ballschläger für den Spieler "schwerer" oder durch die Verkürzung des Schaftes "leichter" gemacht werden. Bei Verwendung nicht zu dicker Einstellscheiben 61,62,63 von beispielsweise einer Dicke von nur wenigen Millimetern kann die Schlägerlänge für viele Anwendungsfälle bereits ausreichend feinstufig eingestellt werden.As already mentioned in the introduction, the extension of the handle shaft can make the ball racket "heavier" for the player or "lighter" by shortening the shaft. When using shims 61, 62, 63 that are not too thick, for example with a thickness of only a few millimeters, the racket length can already be set to a sufficiently fine level for many applications.

Im Falle der Verwendung kompressibler, insbesondere volumenkompressibler Einstellscheiben 6 bzw. 61,62,63 ist die Schraube 9 als Einstellschraube ausgebildet, die durch eine Öffnung 8 im Griffkopf 7 geführt ist. , Der Schraubenschaft 10 ist in ein Gewinde-Sackloch 11 am Ende des Griffschaftes 2 eingeschraubt, wobei der Schraubenkopf 12 von außen gegen die Stirnwand 13 des Griffkopfes 7 drückt und dabei die Einstellscheiben 6 bzw. 61,62,63 je nach Einschraubtiefe mehr oder weniger zusammendrückt.If compressible, in particular volume-compressible adjusting disks 6 or 61, 62, 63 are used, the screw 9 is designed as an adjusting screw which is guided through an opening 8 in the grip head 7. , The screw shaft 10 is screwed into a threaded blind hole 11 at the end of the handle shaft 2, the screw head 12 pressing from the outside against the end wall 13 of the handle head 7 and the adjusting washers 6 and 61, 62, 63 more or less depending on the screw-in depth squeezing.

Je nach Einstellung der Einstellschraube 9 werden die kompressiblen, vorzugsweise volumenkompressiblen Einstellscheiben 6 bzw. 61,62,63 mehr oder weniger zusammengedrückt, wodurch sich die Gesamtlänge des Griffschaftes 2 bzw. des Ballschlägers stufenlos verstellen läßt. Bei dieser Ausgestaltung der Erfindung dienen also die Einstellscheiben 6 bzw. 61, 62,63 nur zur groben Abstufung der Ballschlägerlänge, während die Feinabstufung durch die Einstellkraft der Einstellschraube 9 erzielt wird. Dadurch erhält man eine Gewichtsverlagerung, so daß beispielsweise ein "Medium"-Schläger in Richtung "low" oder "high" verstellbar ist, und damit an das Können, die Spielweise und/oder die Kraft des Spielers jederzeit angepaßt werden kann.Depending on the setting of the adjusting screw 9, the compressible, preferably volume-compressible adjusting disks 6 or 61, 62, 63 are more or less compressed, as a result of which the total length of the handle shaft 2 or of the ball racket can be adjusted continuously. In this embodiment of the invention, the shims 6 and 61, 62, 63 are used only for rough gradation of the length of the ball racket, while the fine gradation is achieved by the adjusting force of the adjusting screw 9. This results in a shift in weight, so that, for example, a "medium" racket can be adjusted in the "low" or "high" direction, and can thus be adapted to the skill, the style of play and / or the strength of the player at any time.

Das Griffende 1 bzw. der Griff 2 sind in an sich bekannter Weise mit einem Griffband 14 umwickelt.The handle end 1 or the handle 2 are wrapped in a manner known per se with a grip tape 14.

Anstelle der Stifte 4 oder zusätzlich zu diesen kann die Einstellscheibe 6 bzw. können die Einstellscheiben 61, 62, 63 eine selbstzentrierende Form aufweisen, so daß sie beim Aufsetzen an die entsprechend geformte Frontseite 3 des Schaftendes 1 und durch Andrücken des Griffkopfes 7 mit der den Einstellscheiben 6 bzw. 61, 62, 63 ebenfalls angepaßten inneren Stirnfläche 15 an die Einstellscheiben 6 bzw. 61, 62, 63 mittels der Einstellschraube 9 von selbst in die richtige axiale Lage gezogen bzw. gedrückt werden. Hierzu sind die Einstellscheiben 6 bzw. 61, 62, 63, die Frontseite 3 und die Stirnfläche 15 des Griffkopfes 7 tellerförmig ausgebildet. Der Tellerrand 16 bewirkt dabei die Zentrierung. Anstelle einer Tellerform kann auch eine Kegel- oder Pyramidenform vorgesehen sein oder eine Scheibenform mit konzentrischen Wellen- und Talringen oder ähnlichen Ausgestaltungen.Instead of the pins 4 or in addition to these, the shim 6 or the shims 61, 62, 63 can have a self-centering shape, so that when they are placed on the correspondingly shaped front 3 of the shaft end 1 and by pressing the handle head 7 with the Adjusting washers 6 or 61, 62, 63 also adapted inner end face 15 to the adjusting washers 6 or 61, 62, 63 by means of the adjusting screw 9 are automatically pulled or pressed into the correct axial position. For this purpose, the shims 6 and 61, 62, 63, the front 3 and the end face 15 of the handle head 7 are plate-shaped. The plate rim 16 causes centering. Instead of a plate shape, a cone or pyramid shape or a disk shape with concentric wave and valley rings or similar configurations can also be provided.

Gemäß der in Figur 2 gezeigten Ausgestaltung der Erfindung kann am Griffkopf 7 ein Hülsenansatz 17 angeformt sein, der gemäß der oberen Hälfte der Figur 2 nur die Einstellscheiben 6 bzw. 61, 62, 63 übergreift. Bei dieser Ausführung erfolgt die Einstellung der Schlägerlänge bei abgenommenem Griffband 14, das anschließend wieder in bekannter Weise befestigt wird.According to the embodiment of the invention shown in FIG. 2, a sleeve attachment 17 can be formed on the grip head 7, which, according to the upper half of FIG. 2, only overlaps the adjusting disks 6 or 61, 62, 63. In this embodiment, the racket length is adjusted with the grip tape 14 removed, which is then fastened again in a known manner.

Der Hülsenansatz 17 kann sich jedoch auch über die gesamte, beispielsweise 20 - 30 cm lange Grifflänge erstrecken, wie anhand der unteren Hälfte der Figur 2 gezeigt ist. Bei dieser Ausführung ist die Feineinstellung der Schlägerlänge ohne Abnahme des Griffbandes 14 möglich.The sleeve extension 17 can, however, also extend over the entire, for example 20-30 cm long handle length, as shown in the lower half of FIG. In this embodiment, the fine adjustment of the racket length is possible without removing the grip 14.

Vorteilhaft ist im Bereich des Endrandes 18 des Hülsenansatzes 17 auf dem Griffschaft 2 eine Markierung 19 eingeprägt und/oder aufgedruckt, die in Verbindung mit dem Endrand 18 des Hülsenansatzes 17 (gemäß Ausführung der unteren Hälfte der Figur 2) eine Einstellmarkierung, beispielsweise eine Skala, bildet. Dadurch kann der Spieler den Ballschläger leicht auf die gewünschte "Schwere" einstellen. Die Rückstellung des Griffkopfes 7 wird bei beiden Varianten der Figur 2 durch die Elastizität der Einstellscheibe (n) 6 bzw. 61, 62, 63 bewirkt.A mark 19 is advantageously embossed and / or printed on the handle shaft 2 in the region of the end edge 18 of the sleeve attachment 17, which, in conjunction with the end edge 18 of the sleeve attachment 17 (according to the design of the lower half of FIG. 2), has an adjustment mark, for example a scale, forms. This allows the player to easily adjust the racket to the desired "severity". The resetting of the grip head 7 is effected in both variants of FIG. 2 by the elasticity of the adjusting disc (s) 6 or 61, 62, 63.

Als Material für die Einstellscheiben 6 bzw. 61, 62, 63 eignet sich jeder nicht zu weiche, gummielastische Werkstoff, insbesondere Weich-Elastomere, wie Kautschuk, Weich-Polyvinylchlorid, Weich-Polyurethan, vorzugsweise in geschäumter Form, Schaum- oder Moosgummi oder auch kompressible Mischpolymerisate oder dgl..Any not too soft, rubber-elastic material, in particular soft elastomers such as rubber, soft polyvinyl chloride, soft polyurethane, preferably in foamed form, foam or foam rubber or else is suitable as material for the adjusting washers 6 or 61, 62, 63 compressible copolymers or the like ..

Der Griffkopf 7, gegebenenfalls mit dem Hülsenansatz 17, besteht vorteilhafterweise aus Metall, wie beispielsweise Aluminium, Zinkdruck- oder Zinkspdtzguß, Messing, Bronze etc., oder aus einem zähelastischen Kunststoff, wie Hart-Polyvinylchlorid, Hart-Polyurethan, Polyamid, Polyäthylen, Polypropylen, Polystyrol etc..The grip head 7, optionally with the sleeve extension 17, advantageously consists of metal, such as aluminum, die-cast zinc or die-cast zinc, brass, bronze, etc., or of a tough elastic plastic, such as hard polyvinyl chloride, hard polyurethane, polyamide, polyethylene, polypropylene , Polystyrene etc.

Der Hülsenansatz 17 besitzt am schlagfeldseitigem Ende des Griffschaftes 2 eine umlaufende Ausnehmung 20, deren Länge der maximalen Verstellung der Einstellscheiben 6 bzw. 61, 62, 63 durch Kompression entspricht. Die Ausnehmung 20 kann durch eineAbschlußscheibe 21 abgedeckt oder ebenfalls mit volumenkompressiblem Material, wie Schaumkunststoff, vollständig ausgefüllt sein.The sleeve extension 17 has a circumferential recess 20 at the end of the handle shaft 2 on the field of impact, the length of which corresponds to the maximum adjustment of the shims 6 or 61, 62, 63 by compression. The recess 20 can be covered by a cover plate 21 or can also be completely filled with volume-compressible material, such as foam plastic.
