Description

Die Erfindung betrifft einen weiter verbesserten Ballschläger (Racket) für Ball- und Federballspiele, wie beispielsweise Tennis, Squash, Badminton, Speedminton, Racquetball.The invention relates to a further improved racket (racket) for ball and badminton games, such as tennis, squash, badminton, speedminton, racquetball.

Ballschläger für Ball- und Federballspiele , mit denen der Spielball geführt und die Schlagkraft des Spielers auf den Ball übertragen wird, sind bereits in den unterschiedlichsten Ausführungen bekannt.Ball bats for ball and badminton games, with which the game ball out and the clout of the player is transferred to the ball, are already known in a variety of versions.

Bei den am weitesten verbreiteten, herkömmlichen Ausführungen - DE 34 34 956 A1 , US 4 997 186 , US 4 919 438 - ist das Schlagteil bzw. die Schlagfläche in der Regel symmetrisch zur Griffachse angeordnet. Das heißt, der Masseschwerpunkt der Schlagfläche liegt auf der Griffachse, wobei die Verlängerung der Griffachse gleichzeitig die Längsachse des Ballschlägers bildet. Ein wesentlicher Nachteil dieser Ballschläger liegt in der ungünstigen Lage der Schlagfläche in Bezug auf die Hand- und Armhaltung des Spielers. Die herkömmlichen Ballschläger mit einer geraden Längsachse von Schlagteil, Schaft und Griff entsprechen nicht den ergonomischen Bedingungen einer effektiven Spieler-Ballschläger-Kombination.In the most widely used, conventional designs - DE 34 34 956 A1 . U.S. 4,997,186 . US 4,919,438 - The impact part or the striking surface is usually arranged symmetrically to the handle axis. That is, the center of gravity of the club face is on the handle axis, wherein the extension of the handle axis simultaneously forms the longitudinal axis of the ball racket. A major disadvantage of this racket lies in the unfavorable position of the club face in relation to the hand and arm posture of the player. The conventional ball bats with a straight longitudinal axis of striker, shaft and handle do not meet the ergonomic conditions of an effective player-ball racket combination.

Die geradlinig verlaufende Längsachse des Ballschlägers verlangt bei der Annahme und Wiedergabe von hohen Bällen eine entsprechend höhere Haltung des Spielarmes des Spielers. Für die optimale Ausführung eines Schlages hinsichtlich Koordinierung und Kraft sollte der Winkel von Spielarm und Ballschläger jedoch unter 45° liegen. Das bedeutet, dass schon leicht höhere Bälle Ballwiedergaben verlangen, die über diesen optimalen Bereich von 45° hinausgehen. Das hat eine extremere Koordinierung und erhöhten Kraftaufwand des Spielerarmes zur Folge.The rectilinear longitudinal axis of the ball racket requires in the acceptance and playback of high balls a correspondingly higher attitude of the game arm of the player. For optimal performance of a punch in terms of coordination and strength, however, the angle of the play arm and ball racket should be below 45 °. This means that even slightly higher balls play ball which exceed this optimum range of 45 °. This results in a more extreme coordination and increased effort of the player's arm.

Die gerade verlaufende, symmetrische Achse von Schlagteil, Schaft und Griff führt ferner dazu, dass der Ballschläger zu einem optimalen Resonanzschwingkörper wird, der die beim Aufnehmen und Schlagen des Balles entstehenden Schwingungen und/oder Vibrationen ungehindert an den Spielarm des Spielers weiterleitet. Dies löst bei jedem Schlag Irritationen des Schlägerarmes aus. Der Spieler versucht, diese Irritationen durch einen festeren Griff, dem sogenannten "betonierten" Handgriff, zu absorbieren, was wiederum zu Verkrampfungen des Handgelenkes bis hin zu krankhaften Erscheinungen, dem sogenannten Tennisarm, und zu Koordinations- und Energieverlusten führt. Infolge der Verkrampfungen müssen alle Muskelgruppen der einzelnen Finger über die des Armes bis zu denen der Schulter nach einem jeden Schlag entkrampft, neu koordiniert und wieder neu fixiert werden. Das bedeutet Zeit-, Konzentrations- und Energieverlust. Die Fixierung des Ballschlägers erfolgt im Handgriff und betrifft somit die Handmuskelgruppen und die damit verbunden Unterarmmuskeln und -sehnen. Der daraus resultierende sogenannte Tennisarm ist daher die Summe der ständigen Überstrapazierung und chronischen Ermüdungs- und Verschleißerscheinurigen, die bei jedem Schlag auftreten.The straight, symmetrical axis of the striker, shaft and handle further results in the ball-beater becoming an optimum resonant vibrating body, which smoothly propagates the vibration and / or vibration generated during picking up and hitting the ball to the player's playing arm. This triggers irritation of the racket arm with each stroke. The player tries to absorb these irritations by a firmer grip, the so-called "concreted" handle, which in turn leads to spasms of the wrist to pathological phenomena, the so-called tennis elbow, and to loss of coordination and energy. As a result of the cramps, all the muscle groups of the individual fingers over the arm up to those of the shoulder after each stroke must be relaxed, re-coordinated and re-fixed. This means loss of time, concentration and energy. The fixation of the ball racket takes place in the handle and thus affects the hand muscle groups and the associated forearm muscles and tendons. The resulting so-called tennis elbow is therefore the sum of the constant overuse and chronic fatigue and wear complaints that occur with every stroke.

Mit dem Ziel, die vorgenannten nachteiligen Eigenschaften zu vermeiden und eine Stabilisierung der Schlägerhaltung zu erreichen, die Trefferquote zu erhöhen, dem Spieler mehr Sicherheit für den gesamtem Spielablauf zu vermitteln und gleichzeitig den Bewegungsablauf im Spiel variabler zu gestalten, sind Ballschläger entwickelt worden, bei denen das Schlagteil bzw. die Schlagfläche oder der Griff des Schlägers zur geradlinig verlaufenden Symmetrie- bzw. Längsachse des Ballschlägers abgewinkelt sind - DE 24 07 213 C1 , FR 2 696 351 , US 4 131 278 , US 4 155 550 . US 4 478 416 , US 4 659 080 . Zu dieser Ausführungsform von Ballschlägern gehört auch der aus WO90/14870 bekannte Tennisschläger, der einen zur verlängerten Griffachse versetzt liegenden Schlägerkopfschwerpunkt aufweist. Hierzu ist der Schlagteile des Tennisschlägers so zu einem geraden Griffteile angeordnet, dass die verlängerte Griffachse weiterhin die Schlagfläche des Schlägerkopfes schneidet, der Schlägerkopfschwerpunkt zur verlängerten Griffachse aber um ein bestimmtes Maß versetzt ist. Die gewünschte Drehstabilität ist bei diesen Schlägern nur dann gewährleistet, wenn der Ball bei einer Schlägerhaltung, in der die Schlagfläche genau senkrecht steht, in einem Winkel von 90° auf die Schlagfläche auftrifft. Durch die versetzte Anordnung des Schlägerkopfschwerpunktes zur verlängerte Griffachse wird bei jedem Schlag, bei dem der Ball nicht unter einem Winkel von 90° auf die senkrecht gehaltene Schlagfläche auftrifft, das Aufkommen eines unerwünschten Drehmomentes, mit den nachteiligen Folgen, wie in den weiteren Ausführungen beschrieben, erhöht. Da in den seltesten Fällen die Bälle direkt in der Verlängerung der Griffachse auf die Schlagfläche auftreffen können die entstehenden Drehmomente infolge der konstruktiven Anordnung und Ausbildung von Schlagteil und Griff des Tennisschlägers über eine Änderung der Griffhaltung bzw. der Griffposition des Spielers nicht ausgeglichen oder diesen Drehmomenten entgegengewirkt werden. Dies ist bei allen Ballschläger mit einer geraden Griffachse, wie auch bei WO 01/87424 A2 der Fall.With the aim to avoid the aforementioned disadvantageous characteristics and to achieve a stabilization of the racket attitude, to increase the hit rate, to give the player more security for the entire course of the game and at the same time to make the course of movement more variable, ball bats have been developed in which the impact part or the striking surface or the handle of the racquet are angled to the rectilinear symmetry or longitudinal axis of the ball racquet - DE 24 07 213 C1 . FR 2 696 351 . US 4,131,278 . US 4 155 550 , US 4,478,416 . US 4,659,080 , To this embodiment of ball bats also includes the WO90 / 14870 known tennis rackets, which has a displaced to the extended handle axis clubhead center of gravity. For this purpose, the impact parts of the tennis racket is arranged to a straight handle parts, that the extended handle axis continues to cut the clubface of the club head, but the club head center of gravity is offset by a certain amount to the extended handle axis. The desired rotational stability is only guaranteed in these rackets when the ball at a racket attitude in which the club face is exactly vertical, impinges on the clubface at an angle of 90 °. Due to the staggered arrangement of the club head center of gravity to the extended handle axis is at any blow in which the ball does not hit at an angle of 90 ° to the vertically held club face, the advent of an undesirable torque, with the adverse consequences, as described in the other remarks elevated. Since in the most rare cases, the balls impinge on the striking surface directly in the extension of the handle axis, the resulting torques due to the structural arrangement and training of striker and handle of the tennis racket on a change in the grip position or the grip position of the player is not compensated or counteracted these torques become. This is with all ball bats with a straight handle axis, as well as with WO 01/87424 A2 the case.

Aus US 4 147 348 , WO 01/87424 A2 und BE 1005097 A5 sind auch bereits Tennisschläger mit einer S-förmigen Anordnung von Schlagteil, Steg und Handgriff bekannt. WO 01/87424 A2 offenbart einen Bellschläger gemäß dem Oberbegriff des Anspruchs 1. Während bei der Ausführung nach WO 01/87424 A2 die verlängerte Griffachse des gerade ausgebildeten Handgriffes den Schwerpunkt des Schlagteiles schneidet, liegt sie bei den Ausführungen nach US 4 147 348 und BE 1005097 A5 weit außerhalb der Schlagfläche und somit weit außerhalb des Sweetspots. Im Fall der BE 1005097 A5 verläuft die verlängerte Griffachse sogar parallel zur Längsachse des Schlagteiles. Der gemeinsame und entscheidende Nachteil dieser Ballschlägerausführungen besteht darin, dass beim Auftreffen und Retournieren des Balles ein extrem hohes Drehmoment entsteht und diesem hohen Drehmoment nur mit einem großen Kraftaufwand und einer noch stärkeren Fixierung des Schlägergriffes in der Hand des Spielers entgegengewirkt werden kann. Ein variables und kontrollierten Retournieren ist dadurch nahezu unmöglich.Out US 4,147,348 . WO 01/87424 A2 and BE 1005097 A5 Tennis rackets are also already known with an S-shaped arrangement of striker, bar and handle. WO 01/87424 A2 discloses a bell-beater according to the preamble of claim 1. While in the embodiment of WO 01/87424 A2 the extended handle axis of the handle formed just cuts the center of gravity of the impact part, it is in the embodiments US 4,147,348 and BE 1005097 A5 far outside of the clubface and thus far out of the sweet spot. In the case of BE 1005097 A5 the extended handle axis even runs parallel to the longitudinal axis of the impact part. The common and crucial disadvantage of these ball racket designs is that when hitting and returning the ball an extremely high torque is created and this high torque can be counteracted only with a great deal of effort and an even stronger fixation of the club grip in the hand of the player. A variable and controlled return is almost impossible.

Darüber hinaus sind bereits unsymmetrische Profilierungen des Handgriffes vorgeschlagen worden, die die Grifftechnik verbessern sollen, um den Schläger noch stärker in der Hand des Spielers zu fixieren und die Übertragung der Schlagkraft auf den Ballschläger zu erhöhen - DE 100 22 298 A1 , US 4 759 546 , DE 24 07 213 C1 .In addition, unsymmetrical profiles of the handle have been proposed to improve the grip technique to fix the racket even more in the hand of the player and to increase the transfer of power to the ball racket - DE 100 22 298 A1 . US 4,759,546 . DE 24 07 213 C1 ,

Eine ergonomische Profilierung des Handgriffes vor, die die Position der Hand zum Griff festlegt wird auch in US 4 147 348 und BE 1005097 A5 vorgeschlagen. Für die Fixierung des Ballschlägers in der Hand des Spielers und für die Übertragung der Schlagkraft sicherlich von Vorteil ist. Der Spielwinkel zwischen der Schlagfläche und dem Balleinschlag kann nur über das Verdrehen des Handgelenkes verändert werden und nicht durch eine variable Veränderung der Griffposition der Hand am Griffteil des Ballschlägers, was beispielsweise bei höher gespielten Bällen von Vorteil wäre.An ergonomic profiling of the handle in front which fixes the position of the hand to the handle is also in US 4,147,348 and BE 1005097 A5 proposed. For the fixation of the ball racket in the hand of the player and for the transmission of the striking power is certainly beneficial. The angle of play between the clubface and the Balleinschlag can only be changed by twisting the wrist and not by a variable change in the grip position of the hand on the handle of the ball racket, which would be advantageous, for example, in higher played balls.

Ein Ballschläger für Racquetball und Tennis mit einem ergonomisch, profiliertem Handgriff und einer zu einer verlängerten Griffachse asymmetrisch ausgebildeten und angeordnete Schlagfläche ist aus US 4 360 201 bekannt. Dieser Ballschläger weist im wesentlichen die gleichen, nachteiligen Spieleigenschaften auf, wie sie vorstehend beschrieben werden.A racquet for racquetball and tennis with an ergonomic, profiled handle and an asymmetrically designed and arranged to a prolonged handle axis club face is out US 4,360,201 known. This ball racquet has substantially the same adverse playing characteristics as described above.

Ein Ballschläger mit bogenförmig gestaltetem Handgriff ist bereits aus US 4 743 021 bekannt. Dieser Ballschläger besitzt wiederum eine Anordnung von Steg und Schlagfläche auf einer geraden Mittellinie, mit den Nachteilen, die beispielsweise vorstehend auf Seite 1 Abs. 3 ff näher beschrieben sind.A ball bat with bow-shaped handle is already off US 4,743,021 known. This ball bat in turn has an arrangement of web and club face on a straight center line, with the disadvantages, which are described in more detail above, for example, on page 1 paragraph 3 ff.

Für ein effektives Aufschlagen, Annehmen und Retournieren des Spielballes ist die Anordnung und Ausbildung des Sweetspots, der sich im Zentrum des Schlagteiles befindet und sich entsprechend den ungleichen Längen der Längs- und Querachse des Schlagteiles zum Rand des Schlagteiles hin ausdehnt, von entscheidender Bedeutung. Der Bereich außerhalb dieses Sweetspots ist wegen der zunehmenden Spannung der Besaitung und der ungünstigen Kräftehebel beim Retournieren des Balles zunehmend ungünstig. Ein Spiel mit diesen Abschnitten des Schlagteiles ist wesentlich unkoordinierter und erfordert einen höheren Krafteinsatz.For effective hitting, accepting and returning the ball is the arrangement and training of the sweet spot, which is located in the center of the percussion part and according to the unequal lengths of the longitudinal and transverse axis of the percussion part expands towards the edge of the percussion part, is of crucial importance. The area outside of this sweetspot is increasingly unfavorable because of the increasing tension of the strings and the unfavorable levers when returning the ball. A game with these sections of the strike part is much more uncoordinated and requires a greater use of force.

Bei der Ballwiedergabe geht es vor allem um die Führung des Balles, die möglichst lang sein sollte. Je länger die Längs- und Querachse des Sweetspots, umso geschmeidiger ist die mit dem Ball in Kontakt befindliche Saite der Bespannung des Schlagteiles. Hierdurch verlängert sich die Wegstrecke, die der Spielball auf der Besaitung des Schlagteiles zurücklegt und kann auf diese Weise länger geführt und kontrolliert werden. Ein Spiel über die Längsachse des Sweetspots ist daher wesentlich vorteilhafter als das Spiel entlang der kürzeren Querachse, was bei Slice- und Topspinbällen mit herkömmlichen Ballschlägern, die eine geradlinig verlaufende Längsachse aufweisen, regelmäßig der Fall ist. Die vorstehend beschriebenen, bekannten Ballschläger mit einem zur geraden Schlägerachse abgewinkelten Schlagteil, besitzen bereits eine verlängerte Wegstrecke für die Führung und Kontrolle des Balles nach dem Auftreffen auf die Besaitung des Schlagteiles und verfügen somit über einen vergrößerten Sweetspot mit den Vorteilen, die sich daraus für das Annehmen und Retournieren des Balles ergeben. Trifft jedoch der Ball auf die Flächen des Schlagteiles, die außerhalb des vergrößerten Sweetspots liegen, entsteht ein ungleich höheres Hebelmoment, dem nur mit einem erhöhten Krafteinsatz entgegengewirkt werden kann. Dieses höhere Hebelmoment ruft ein Verdrehen des Schaftes mit dem Griff hervor und führt zu Kontroll- und Kraftverlusten.When playing ball, it's all about the leadership of the ball, which should be as long as possible. The longer the longitudinal and transverse axis of the sweet spot, the smoother the string in contact with the ball is the covering of the striking part. This prolongs the distance covered by the game ball on the stringing of the striker and can be guided and controlled longer in this way. A game on the longitudinal axis of the sweet spot is therefore much more advantageous than the game along the shorter transverse axis, which is regularly the case for slice and top spin balls with conventional ball bats, which have a straight longitudinal axis. The above-described, known ball racquets with an angled to the straight racquet axis impact part, already have a prolonged path for the guidance and control of the ball after hitting the Besaitung the striker and thus have an enlarged sweet spot with the advantages that result from the Receiving and returning the ball revealed. But hits the ball on the surfaces of the impact part, which lie outside of the enlarged sweet spot, creates a much higher lever torque, which can be counteracted only with an increased use of force. This higher moment of leverage causes the shank to twist with the handle and leads to loss of control and power.

Bei den weiterentwickelten Ballschlägern mit einem zur geradlinig verlaufenden Längsachse abgewinkelten Griffteil sind die Verhältnisse ähnlich. Der abgewinkelte Griff entlastet zwar das Handgelenk, jedoch löst jeder auf das Schlagteil auftreffende Ball ein Hebelmoment aus, das außerhalb der Kraftlinie des Spielarmes liegt. Die Kraftlinien verlaufen bei einem abgewinkelten Griff weit außerhalb des Schlagteiles und können so nur zum Teil dem auftretenden Hebelmoment entgegenwirken.In the advanced ball racquets with an angled to the rectilinear longitudinal axis handle part, the conditions are similar. Although the angled handle relieves the wrist, but triggers each impact on the impact ball from a lever moment, which is outside the line of force of the play arm. The lines of force run at an angled handle far outside the percussion part and can counteract only part of the lever torque occurring.

Zusammenfassend bleibt daher festzustellen, dass durch das Abwinkeln des Schlagteiles oder des Griffes der Ergonomie des Bewegungsablaufes besser entsprochen werden kann. Diese Ausführungen des Ballschlägers rufen andererseits aber einen negativen Krafthebel hervor, der sich ungünstig auf das Aufnehmen und Retournieren des Balles auswirkt.In summary, therefore, it should be noted that the bending of the impact part or the handle of the ergonomics of the movement process can be better met. On the other hand, however, these embodiments of the ball-striking device produce a negative force lever, which has an unfavorable effect on the pick-up and return of the ball.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Ballschläger mit insgesamt verbesserten Spieleigenschaften zu entwickeln, der sich weitgehend an die ergonomischen Bewegungsabläufe des Spielers beim Aufnehmen und Retournieren des Spielballes anpasst und noch effektivere Ausnutzung der Schlagkraft ermöglicht.The invention is therefore an object of the invention to develop a ball racket with overall improved game characteristics, which largely adapts to the ergonomic movement of the player when recording and returning the game ball and even more effective use of the power allows.

Erfindungsgemäß wird diese Aufgabe durch einen Ballschläger nach den Merkmalen von Patentanspruch 1 gelöst. Vorteilhafte Weiterbildungen des erfindungsgemäßen Ballschlägers ergeben sich aus den Unteransprüchen 2 bis 8. Der erfindungsgemäße Ballschläger besitzt insgesamt eine S-förmige Konfiguration und weist eine für das Schlagteil-, den Schaft und den Griff gemeinsame s-förmig verlaufende Mittellinie in der Weise auf, dass der obere und der untere Scheitelpunkt des Kopfrahmens und des Schlagteiles auf der Mittellinie liegen, während die Anordnung von Schaft und Griff in ihrer Längserstreckung dem Verlauf der Mittellinie folgen, wobei die bogenförmige Ausbildung des Griffes sich in der konstruktiven Ausführung des Schaftes fortsetzt.According to the invention this object is achieved by a ball racket according to the features of claim 1. Advantageous developments of the ball bat according to the invention will become apparent from the dependent claims 2 to 8. The ball bat according to the invention has an overall S-shaped configuration and has an S-shaped centerline common to the striker, shank and grip such that the top and bottom vertices of the head frame and striker lie on the centerline , While the arrangement of the shaft and handle in their longitudinal extension follow the course of the center line, wherein the arcuate design of the handle continues in the structural design of the shaft.

Gemäß einer Ausführungsform sind die Querschnitte der Profile von Kopfrahmen und Schaft in den durch die Mittellinie getrennten Hälften des Schlägers unterschiedlich.According to one embodiment, the cross sections of the profiles of the head frame and the shank are different in the halves of the racket separated by the center line.

Einer der wesentlichen Vorteile des neuen Ballschlägers besteht darin, dass die beim Aufschlag, Annehmen und Retournieren des Balles auftretenden Schwingungen nicht in dem Maße an den Spielarm des Spielers weitergeleitet oder gar verstärkt werden, wie es bei Ballschlägern mit einer geraden Längsachse der Fall ist. Die s-förmige Konfiguration des Ballschlägers, insbesondere die des Schaftes wirkt wie eine Feder und zehrt einen großen Anteil der auftretenden Schwingungen auf. Der erfindungsgemäße Ballschläger dämpft die Resonanz der Schwingung und trägt so zu einer Schonung des Spielarmes bei. Die schwingungsdämpfenden Wirkungen können noch durch Erweiterungen des Profilquerschnittes verstärkt werden, die im Bereich des Endpunktes des Griffes vorgesehen werden - Anspruch 3.One of the main advantages of the new ball-racket is that the vibrations that occur when the ball is picked up, picked up and returned are not transmitted or amplified to the player's playing arm to the same extent as is the case with ball-beaters with a straight longitudinal axis. The s-shaped configuration of the ball-racket, in particular that of the shaft acts as a spring and consumes a large proportion of the vibrations occurring. The ball bat according to the invention dampens the resonance of the vibration and thus contributes to a protection of the game arm. The vibration damping effects can be reinforced by extensions of the profile cross-section, which are provided in the region of the end point of the handle - claim 3.

Die s-förmige Konfiguration des Ballschlägers führt nicht nur dazu, dass der vorgeschlagene Ballschläger gegenüber den bisher bekannten Ausführungen noch weitgehender an die ergonomischen Bewegungsabläufe beim Aufschlag, Annehmen und Retournieren des Balles angepasst wird, sondern führt vorteilhafter Weise zu einer Verschiebung des Schlagteils in Bezug zu einer durch den Schwerpunkt des Griffes gehenden Schwerpunktachse. Im Vergleich zu herkömmlichen Ballschlägern kann daher bei gleichem Winkel zwischen Spielerarm und Körper des Spielers der Ball höher gespielt werden. Diese Eigenschaft, die beim Spiel am Netz besonders von Vorteil ist, verringert den erforderlichen Krafteinsatz und erhöht die Kontrolle des Balles beim Schlag.The s-shaped configuration of the ball racket not only results in that the proposed racket is compared to the previously known versions even more adapted to the ergonomic movement sequences when serving, accepting and returning the ball, but advantageously leads to a shift of the percussion part in relation to a gravity axis passing through the center of gravity of the handle. Compared to conventional ball bats, therefore, the ball can be played higher at the same angle between the player's arm and the player's body. This feature, which is particularly beneficial when playing on the net, reduces the amount of power required and increases the control of the ball when hit.

Die Krümmung des Griffes, dessen Anfangs- und Endpunkt auf der s-förmig verlaufenden Mittellinie des Ballschlägers liegt, unterstützt zusätzlich den variablen Einsatz des erfindungsgemäßen Ballschlägers sowohl bei Vorhand- als auch bei Rückhandbällen und ermöglicht eine noch bessere Nutzung der Vorteile, die sich aus der Verschiebung bzw. Auslenkung des Schlagteils ergeben. Außerdem ist der Griff durch seine Krümmung noch besser an den Handbogen des Spielers angepasst. Es entsteht ein größerer Griffkontakt, durch den der Schläger noch besser in der Hand des Spielers fixiert wird. Gleichzeitig ist der gekrümmte Griff ein wirksamer Hebel gegen Verdrehungen des Schlägers, die durch Bälle entstehen, die nicht mit dem Sweetspot angenommen und geschlagen werden.The curvature of the handle, whose start and end point is on the s-shaped center line of the ball racket, additionally supports the variable use of the ball racket according to the invention both forehand and backhand balls and allows an even better use of the advantages arising from the Displacement or deflection of the percussion part result. Besides that is the handle is even better adapted to the player's bow due to its curvature. It creates a greater grip contact, through which the racket is better fixed in the hand of the player. At the same time, the curved handle is an effective lever against the racket's twisting, caused by balls that are not accepted and hit by the sweetspot.

Ein weiterer, wesentlicher Vorteil des erfindungsgemäßen Ballschlägers besteht vor allem darin, dass durch die s-förmige Konfiguration und die gemeinsame s-förmig verlaufende Mittellinie die unvorteilhaften Hebelmomente, die sich beispielsweise aus einer abgewinkelten Anordnung von Griff und/oder Schlagteil ergeben, kompensiert werden, d. h. sich gegenseitig aufheben.A further, significant advantage of the ball impactor according to the invention is, above all, that the unfavorable lever moments which result, for example, from an angled arrangement of the handle and / or impact part, are compensated by the S-shaped configuration and the common S-shaped center line, d. H. cancel each other out.

Mit der Verschiebung resp. Auslenkung des Schlagteiles, wie vorstehend beschrieben, verdreht sich auch das Achsenkreuz des Sweetspots in Bezug auf die Flugbahn des ankommenden Balles und verändert gleichzeitig die wirksame Fläche des Sweetspots. Der ankommende Flugball wird dadurch nicht vorrangig von den Längssaiten der Bespannung des Schlagteiles aufgenommen, wie es bei Ballschlägern mit einer geraden Längsachse allgemein der Fall ist, sondern wird von den Längs- und Quersaiten der Bespannung aufgenommen, die in etwa diagonal zur Flugbahn des Balles gerichtet sind - Anspruch 4. Dieser vorteilhafte Effekt lässt sich noch dadurch erhöhen, indem die Längssaiten der Bespannung nicht parallel zur einer Verbindungslinie zwischen den äußersten Punkten des Kopfrahmens des Schlagteiles verlaufen, sondern in etwa diagonal angeordnet werden - Anspruch 5. Der Ball muss dann einen längeren Weg auf der Bespannung des Schlagteiles zurücklegen und erhält dadurch eine längere Führung. Gleichzeitig erhöht sich die umfassende Kontrolle des Balles. Aus der quasi doppelten Führung des Balles entlang der Längs- und Quersaiten der Bespannung ergibt sich neben der verbesserten Kontrolle des Balles auch eine effizientere Übertagung der Schlagkraft auf den Ball.With the shift resp. Deflection of the impact part, as described above, also twists the axbox of the sweet spot with respect to the trajectory of the incoming ball and simultaneously changes the effective area of the sweet spot. The incoming flight ball is thereby not primarily absorbed by the strings of the strings of the striker, as is generally the case with ball-beaters with a straight longitudinal axis, but is taken up by the longitudinal and transverse strings of the string, which are directed approximately diagonally to the trajectory of the ball This advantageous effect can be further increased by the longitudinal strings of the fabric not parallel to a connecting line between the outermost points of the head frame of the striker, but are arranged approximately diagonally - claim 5. The ball must then a longer Travel back on the covering of the striker and thus receives a longer guide. At the same time, the overall control of the ball increases. From the quasi double leadership of the ball along the longitudinal and transverse strings of the clothing results in addition to the improved control of the ball and a more efficient transfer of the impact force on the ball.

Ein wirksames Aufschlagspiel und die Slice- und Tospin-gespielten Bälle erfordern ein Anschneiden des geschlagenen Balles. Hierzu wird in der Regel das Schlagteil des Ballschlägers durch den Spieler in Bezug auf die Flugbahn des Balles unter einem Winkel leicht angestellt, um die Flugbahn des Balles zu schneiden und den gespielten Ball mit einem Dralleffekt zu beaufschlagen. Die Schlagkraft wird dadurch nicht vollständig auf den Ball übertragen. Es entstehen Kraftverluste.An effective service game and the Slice and Tospin-played balls require a cut of the beaten ball. For this purpose, the impact part of the ball racket is usually made by the player with respect to the trajectory of the ball at an angle slightly to cut the trajectory of the ball and act on the ball played with a swirling effect. The impact is not completely transferred to the ball. There are power losses.

Durch die erfindungsgemäße s-förmige Konfiguration des Ballschlägers, die damit verbundene Auslenkung des Schlagteiles und die Führung des geschlagenen oder ankommenden Balles auf den Quer- und Längssaiten der Bespannung des Schlagteiles, ergänzt durch die Anordnung der Besaitung, wie vorstehend beschrieben, erhält der Ball eine Drehung um seine eigene Achse, die eine Beaufschlagung des Balles mit einem Dralleffekt auslöst, ohne dass der Spieler den Ball anschneiden muss. Die gesamte Schlagkraft des Schlages wird dabei auf den Ball übertragen.By the inventive S-shaped configuration of the ball racket, the associated deflection of the striker and the leadership of the beaten or incoming ball on the transverse and longitudinal strings of the string of the impact part, supplemented by the arrangement of the stringing, as described above, the ball receives a Rotation around its own axis, which triggers the ball with a swirling effect without the player having to cut the ball. The entire power of the blow is transferred to the ball.

Ohne die verbesserten Spiel- und sonstigen, vorteilhaften Eigenschaften negativ zu beeinflussen, kann der erfindungsgemäße Ballschläger mit einem symmetrisch oder asymmetrisch gestalteten Schlagteil ausgestattet sein. Der Ballschläger besitzt wiederum eine s-förmige Konfiguration. Mit der asymmetrischen Form des Schlagteiles verlängert sich gleichzeitig die Länge der Längssaiten der Bespannung und auch die Länge des Schlaghebels. Hieraus entsteht resultierend eine größere Schlagkraft und eine größere Fläche des Sweetspots, die die Führung und Kontrolle des Balles auf dem Schlagteil verbessert.Without negatively influencing the improved play and other advantageous properties, the ball racket according to the invention can be equipped with a symmetrically or asymmetrically designed striking part. The ball racket in turn has an s-shaped configuration. With the asymmetrical shape of the impact part lengthens the length of the strings of the strings and also the length of the hammer. This results in a greater impact force and a larger area of the sweet spot, which improves the guidance and control of the ball on the striker.

Andererseits entstehen mit der asymmetrischen Ausbildung des Schlagteiles Unwuchten, die im Bewegungsablauf beim Schlagen des Balles Drehmomente hervorrufen. Diese Drehmomente sind in soweit erwünscht, wenn auf den Ball dadurch ein Dralleffekt übertragen wird. Sie sind jedoch dann unerwünscht und von Nachteil, wenn diese Drehmomente se sehr stark werden und der Ballschläger in der Hand des Spielers zum Verdrehen neigt. Diesem Umstand wird nach der Erfindung dadurch entgegengewirkt, dass das Profil des Querschnittes von Schaft und Schlagteil in den durch die Längsachse getrennten, gegenüberliegenden Hälften des Ballschlägers ungleich ist - Anspruch 8.On the other hand arise with the asymmetric design of the impact part imbalances that cause torques in the movement when hitting the ball. These torques are desirable in so far, if on the ball thereby a swirl effect is transmitted. However, they are then undesirable and disadvantageous when these torques se are very strong and the ball bats in the hand of the player tends to twist. This circumstance is counteracted according to the invention in that the profile of the cross section of the shaft and impact member in the separated by the longitudinal axis, opposite halves of the ball racquet is unequal - claim 8.

Vorteilhafter Weise wird der erfindungsgemäße Ballschläger einstückig hergestellt - Anspruch 6. Um die Fertigung gegebenenfalls zu vereinfachen und zu dezentralisieren können die einzelnen Funktionsbaugruppen des Ballschlägers separat hergestellt und in einem Montageprozess durch Kraft- und/oder Formschlussverbindungen fest miteinander verbunden werden - Anspruch 7.Advantageously, the ball racket according to the invention is produced in one piece. Claim 6 To simplify and decentralize the production, the individual functional assemblies of the ball racket can be manufactured separately and firmly connected together in a mounting process by force and / or positive connection.

Wie aus Fig.1 hervorgeht, besitzt der nach der Erfindung hergestellte Ballschläger durchgehend eine s-förmige Konfiguration mit einer s-förmig verlaufenden Mittellinie 5, auf der die Anfangspunkte und Endpunkte der Funktionselemente des Ballschlägers Schlagteil 1, Schaft 2 und Griff 3 angeordnet sind. Der dargestellte Ballschläger weist ein symmetrisch geformtes Schlagteil 1 auf, das durch den Kopfrahmen 6 und die Besaitung 7 gebildet wird. Aus dieser neuen, konstruktiven Gestaltung ergeben sich eine Reihe vorteilhafter Eigenschaften, die in den vorangegangenen Ausführungen bereits umfassend dargestellt wurden. Um Wiederholungen zu vermeiden, wird im vorliegenden Teil der Erfindungsbeschreibung auf diese verbesserten Spiel- und sonstigen vorteilhaften Eigenschaften nicht mehr detailliert eingegangen.How out Fig.1 As can be seen, the ball bat produced according to the invention has a continuous S-shaped configuration with an S-shaped extending center line 5, on which the starting points and end points of the functional elements of the ball racket striker 1, shaft 2 and handle 3 are arranged. The ball bat shown has a symmetrically shaped impact member 1, which is formed by the head frame 6 and the string 7. This new, constructive design results in a number of advantageous properties, which have already been comprehensively represented in the preceding embodiments. In order to avoid repetition, this improved game and other advantageous properties will not be discussed in detail in the present part of the description of the invention.

Zur Stabilisierung und zu einer variablen Gestaltung der Schlägerhaltung trägt der bogenförmig ausgeführte Griff 3 bei, der zudem noch besser an den Handbogen des Spielers angepasst ist und dadurch noch stärker in der Hand des Spielers fixiert werden kann.For stabilization and a variable design of the racket attitude contributes to the arcuate handle 3, which is also better adapted to the hand of the player and thus can be fixed even more in the hand of the player.

Durch den s-förmigen Verlauf der Mittellinie 5 verdreht sich auch das Achsenkreuz des Sweetspots 9 im Zentrum des Schlagteiles 1 in Bezug auf die Flugbahn des ankommenden Balles. Wie bereits dargelegt, ergeben sich hieraus wesentliche Vorteile beim Annehmen und Retournieren des Balles, da dieser eine längere Wegstrecke auf der Besaitung des Schlagteiles 1 zurücklegt und dadurch besser geführt und kontrolliert werden kann. Durch die Verdrehung des Achsenkreuzes des Sweetspots 9 verlaufen die Längs- und Quersaiten in etwa diagonal zur Flugbahn des Balles. Im Gegensatz zu den bisher bekannten Ballschlägern wird der Ball über eine verlängerte Wegstrecke sowohl entlang der Längssaiten als auch der Quersaiten geführt. Hierdurch erhöht sich die Übertragung der Schlagkraft auf den Ball, wobei dieser gleichzeitig um seine eigene Achse gedreht wird. Der Ball erhält auf diese Weise einen zusätzlichen Dralleffekt, ohne dass der Spieler den Ball gesondert anschneiden muss. Diese vorteilhaften Wirkungen können noch dadurch verstärkt werden, indem die Längssaiten der Besaitung 7 nicht parallel zu einer Verbindungslinie 14 zwischen den äußersten Punkten des Kopfrahmens 6 des Schlagteiles 1 angeordnet sind, sondern in etwa diagonal zu dieser Linie 14 verlaufen.Due to the s-shaped course of the center line 5, the coordinate system of the sweet spot 9 in the center of the impact part 1 in relation to the trajectory of the incoming ball twisted. As already stated, this results in significant advantages when accepting and returning the ball, since it travels a longer distance on the stringing of the striker part 1 and thus can be better guided and controlled. Due to the rotation of the axbox of the sweet spot 9, the longitudinal and transverse strings run approximately diagonally to the trajectory of the ball. In contrast to the hitherto known ball bats, the ball over an extended distance both along the Long strings and the cross strings led. This increases the transmission of the impact force on the ball, which is simultaneously rotated about its own axis. The ball receives in this way an additional swirl effect, without the player having to cut the ball separately. These advantageous effects can be further enhanced by the longitudinal strings of the stringing 7 are not arranged parallel to a connecting line 14 between the outermost points of the head frame 6 of the impact member 1, but extend approximately diagonally to this line 14.

Eine weitere Maßnahme, die wirksame Fläche des Sweetspots 9 zu vergrößern, besteht darin, dass man in an sich bekannter Weise auf den Steg 4 des Kopfrahmens 6 verzichtet und die Längs- und Quersaiten der Bespannung des Schlagteiles 1 bis in den Kopfbereich des Schaftes 2 führt und dort verankert.Another measure to increase the effective area of the sweetspot 9 is that it dispenses with the web 4 of the head frame 6 in a manner known per se and guides the longitudinal and transverse strings of the clothing of the striking part 1 into the head region of the shaft 2 and anchored there.

Die bogenförmige Ausbildung des Griffes 3 setzt sich in der konstruktiven Ausführung des Schaftes 2 fort, wobei Anfangs- und Endpunkt des Griffes 2 ebenfalls auf der s-förmig verlaufenden Mittellinie 5 des Ballschlägers liegen. Die Ausführung des Schaftes 2 wirkt wie eine Feder und dämpft die beim Schlagen und Annehmen des Balles auftretenden Schwingungen. Die Dämpfungseigenschaften des vorgeschlagenen Ballschlägers können zusätzlich noch durch eine Erweiterung des Profilquerschnittes 8 im Bereich der Anschlussstelle von Steg 2 und Griff 3 verstärkt werden.The arcuate design of the handle 3 is continued in the structural design of the shaft 2, wherein the starting and ending point of the handle 2 are also on the s-shaped extending center line 5 of the ball racket. The design of the shaft 2 acts like a spring and dampens the vibrations occurring when hitting and picking up the ball. The damping properties of the proposed ball racket can be additionally reinforced by an extension of the profile cross-section 8 in the region of the junction of web 2 and handle 3.

Der nach der Erfindung hergestellte und in Fig. 3 dargestellte Ballschläger besitzt ein asymmetrisch ausgebildetes Schlagteil 1. Durch diese Konfiguration des Schlagteiles 1 vergrößert sich der Sweetspot 9 um die Sweetspotfläche 9.1. Gleichzeitig verlängert sich auch der Schlaghebel des Ballschlägers mit der Folge, dass eine höhere Schlagkraft auf den Ball übertragen werden kann. Aus der flächenmäßigen Vergrößerung des Sweetspots ergibt sich ferner eine bessere Führung und Kontrolle des Balles während seines Kontaktes mit der Bespannung des Schlagteiles 1.The produced according to the invention and in Fig. 3 shown ball bat has an asymmetrically formed impact member 1. By this configuration of the impact member 1, the sweet spot 9 increases to the sweet spot area 9.1. At the same time, the hammer of the ball racket is extended, with the result that a higher impact force can be transferred to the ball. From the areal enlargement of the sweetspot, there is also a better guidance and control of the ball during its contact with the covering of the striking part 1.

Um möglichen Problemen, die beim Schlagen des Balles durch hohe Drehmomente infolge der asymmetrischen Ausbildung des Schlagteiles 1 ausgelöst werden, zu begegnen, haben die Profile 6.1; 6.2 des Kopfrahmens 6 und des Schaftes 2 in den durch die Mittellinie 5 getrennten Balischlägerhälfte einen unterschiedlichen Profilquerschnitt. Durch eine geeignete Auswahl dieser, voneinander abweichenden Profilquerschnitte, können die Unwuchten des Ballschlägers, die sich aus der asymmetrischen Ausbildung des Schlagteiles 1 ergeben, kompensiert werden.To counteract possible problems that are triggered by high torques when hitting the ball as a result of the asymmetric design of the impact member 1, the profiles have 6.1; 6.2 of the head frame 6 and the shaft 2 in the separated by the center line 5 Balischlägerhälfte a different profile cross-section. By a suitable choice of these, from each other Deviating profile cross-sections, the imbalances of the ball-racket, resulting from the asymmetric design of the impact member 1, can be compensated.
