Definitions
- the present invention relates to a handle for tennis rackets and related impact sports equipment such as squash and badminton rackets, in which it is important that the object moving in the air with more or less high speed is hit precisely and, if necessary, powerfully, the stroke frequency and thus the muscle load can be very high.
- the handles for tennis rackets known today are designed so that their cross-section consists of a symmetrical, irregular octagon, in which the opposite legs are each parallel and of equal length.
- the octagon consists of four pairs of legs, with a first pair of legs parallel to the club face, a second at right angles and the third and fourth diagonally.
- the two legs arranged parallel to the face are somewhat longer than the ones lying transversely to it, the shortest are the legs arranged diagonally to the face.
- the known handle cross-sections which closely approximate the circle, offer a rotation resistance that is far too small and are therefore only suitable to a limited extent for sports equipment of the types mentioned at the beginning.
- the cross-section of current tennis racket handles is also disadvantageous because the grip of the fingers and thumbs is insufficient.
- the adjacent legs of the octagon do not form good conditions for optimal grip due to the obtuse angle they enclose, since the octagon is too close to the circle. Therefore, in order to be able to be held securely, the handle has to be gripped more positively than positively, which is tired and can lead to health damage if the sport is exercised frequently and intensively, the so-called "tennis elbow".
- shock absorption should be pointed out. Since the handle of modern tennis racquets has a relatively large cross-sectional width (across the face of the club face) and is also designed for double-handed shooting, so it is very long, it can make practically no contribution to shock absorption.
- the damping zone is limited to the shaft area, i.e. H. on the short part between the handle and the club head. The load on the arm muscles is therefore correspondingly high, especially with high impact cadence and great physical exertion.
- the present invention is therefore based on the object to provide a handle of the type mentioned above, which eliminates the disadvantages listed and yet meets all requirements.
- it should enable the club's face to be positioned securely on the basis of purely sensorimotor information, have a high resistance to the torques occurring on the handle and at the same time ensure that the punch is essential for vigorous hitting.
- it should be designed so that the grip area of the racket can take over an arm-protecting damping function.
- Such a design creates a clear position of the handle in the hand, and thus the striking surface in relation to the position of the hand, which can be easily sensed by the sensor motor and creates a high resistance to rotation, which means that the racket has to be clutched with less force than was previously the case and therefore largely spared from twists.
- the pronounced edges of the handle according to the invention are arranged in such a way that they fit optimally into the skeletal articulations of the hand with regard to non-positive and positive locking. The use of a racket with a handle according to the invention therefore leads to less fatigue and less sweating.
- the rear area of the handle according to the invention is designed in such a way that an optimal fist closure is guaranteed, ie the hand cavity with a clenched fist is completely supported, which is of great size It is important for performing powerful blows.
- This clasp is also when changing handles, z. B. received unchanged from forehand to backhand.
- the small cross-sectional width in the main area of the handle according to the invention considerably extends the damping zone of the racket shaft, whereby the risk of the tennis elbow symptom can be reduced.

Abstract
Description
HANDGRIFF FUER SCHLAGSPORTGERÄTE HANDLE FOR STRIKE SPORTS EQUIPMENT
Gegenstand der vorliegenden Erfindung ist ein Handgriff für Tennisschläger und verwandte Schlagsportgeräte wie Squash- und Federballschläger, bei denen es darauf ankommt, dass der sich in der Luft mit mehr oder weniger hohem Tempo bewegende Gegenstand präzise und nötigenfalls kraftvoll getroffen wird, wobei die Schlagfrequenz und damit die Muskelbelastung sehr hoch sein kann. The present invention relates to a handle for tennis rackets and related impact sports equipment such as squash and badminton rackets, in which it is important that the object moving in the air with more or less high speed is hit precisely and, if necessary, powerfully, the stroke frequency and thus the muscle load can be very high.
Die heute bekannten Handgriffe für Tennisschläger sind so ausgebildet, dass ihr Querschnitt aus einem symmetrischen, unregelmässigen Achteck besteht, bei dem die sich gegenüberliegenden Schenkel jeweils parallel und gleich lang sind. Das Achteck besteht demnach aus vier Schenkelpaaren, wobei ein erstes Schenkelpaar parallel zur Schlagfläche des Schlägers steht, ein zweites rechtwinklig und das dritte und vierte diagonal dazu. Die zwei parallel zur Schlagfläche angeordneten Schenkel sind etwas langer als die quer dazu liegenden, am kürzesten sind die diagonal zur Schlagfläche angeordneten Schenkel. The handles for tennis rackets known today are designed so that their cross-section consists of a symmetrical, irregular octagon, in which the opposite legs are each parallel and of equal length. The octagon consists of four pairs of legs, with a first pair of legs parallel to the club face, a second at right angles and the third and fourth diagonally. The two legs arranged parallel to the face are somewhat longer than the ones lying transversely to it, the shortest are the legs arranged diagonally to the face.
Der grosse Nachteil dieser achteckigen, mehrfach symmetrischen Ausbildung des Griffquerschnittes besteht darin, dass der wenig geübte Spieler nicht sensomotorisch und ohne daran zu denken spürt, in welcher Stellung er das Schlagsportgerät, und demnach die in einer bestimmten Lage bezüglich des Griffes liegende Schlagfläche desselben hält. Dies ist aber insbesondere in der unmittelbaren Schlagphase von ausschlaggebender Bedeutung, denn nur so ist die Abgabe eines korrekten Schlages möglich. Und da der Spieler nicht die Zeit hat, die Stellung des Schlagers von Beginn der Ausholbewegung an bis zum Aufprall, resp. Schlag des Balles visuell zu verfolgen, da er sich vielmehr darauf konzentrieren muss, den Ball ununterbrochen zu beobachten, richtig zum Ball zu stehen, richtig auszuholen, zu schlagen, zu führen etc., muss durch die Formgebung des Handgriffes sichergestellt werden, dass ihm die Stellung des Schlägers sensomotorisch automatisch und mit grösstmöglieher Sicherheit bewusst wird. The major disadvantage of this octagonal, multi-symmetrical design of the grip cross-section is that the inexperienced player does not feel sensor-motorically and without thinking about the position in which the striking sports device is held, and accordingly the striking surface of the striking device in a certain position with respect to the grip. However, this is of crucial importance, especially in the immediate striking phase, because this is the only way to deliver a correct punch. And since the player does not have the time to position the hit from the start of the outward movement until the impact, respectively. Track the ball visually as it hits Rather, it has to focus on continuously watching the ball, standing correctly at the ball, properly swinging, striking, guiding etc., the shape of the handle must ensure that the position of the racket is automatically senso-motorized and with the greatest possible safety becomes aware.
Durch die bekannte Form der Handgriffe mit der etwas grösseren Länge der parallel zur Schlagfläche stehenden Schenkel des achteckigen Griffquerschnittes ist zwar eine gewisse sensomotorische Differenzierung der Stellung des Schlägers gegeben. Diese reicht aber erfahrungsgemäss, zumindest beim ungeübten Spieler nicht aus, um die Stellung der Schlagfläche in der Schlagphase ohne visuelle Kontrolle zu orten, resp. zu spüren. Deshalb entstehen beim ungeübten Spieler sehr viele Fehler dadurch, dass die Stellung der Schlagfläche während der Schlagphase ungünstig ist. The known shape of the handles with the somewhat longer length of the legs of the octagonal grip cross section parallel to the striking surface does indeed provide a certain sensorimotor differentiation of the position of the racket. Experience has shown that this is not sufficient, at least for inexperienced players, to locate the position of the face in the striking phase without visual control, or to feel. Therefore, inexperienced players make a lot of mistakes due to the fact that the position of the face is unfavorable during the striking phase.
Ein weiterer Mangel derartiger bekannter Handgriffe mit achteckigem Querschnitt liegt daran, dass sie in der Hand einen relativ niedrigen Widerstand gegen Verdrehungen der Schlagfläche bieten. Wenn man davon ausgeht, dass der Ball sehr oft nicht genau in der Mitte der Schϊagfläche getroffen wird, d. h. nicht in der verlängerten Mittellinie des Handgriffes auftrift, ist es aber f ü r einen Handgriff von grosserAnother shortcoming of such known handles with an octagonal cross-section is that they offer a relatively low resistance to twisting of the face in the hand. If one assumes that the ball very often is not hit exactly in the middle of the striking surface, d. H. does not hit the extended center line of the handle, but it is larger for a handle
Wichtigkeit, dass er ohne übergrossen Kraftaufwand dem Spieler ermöglicht, die sich daraus ergebenden Drehmomente aufzufangen, ohne dass sich der Schläger in der Hand verdreht. Die bekannten Handgriffquerschnitte, die sich stark dem Kreis annähern, bieten dazu aber einen wesentlich zu kleinen Verdrehungswiderstand und sind daher für Sehlagsportgeräte der eingangs erwähnten Arten nur bedingt geeignet. Weiter ist der Querschnitt derzeitiger Handgriffe von Tennisschlägern auch deshalb nachteilig, weil die Griffigkeit der Finger und Daumen ungenügend ist. Die jeweils benachbarten Schenkel des Achtecks bilden aufgrund des von ihnen eingeschlossenen stumpfen Winkels keine guten Voraussetzungen für eine optimale Griffigkeit, liegt doch das Achteck zu nahe am Kreis. Daher muss der Handgriff, um sicher gehalten werden zu können, mehr kraftschlüssig als formschlύssig umgriffen werden, was ermüdet und bei häufiger und intensiver Ausübung des Sportes zu gesundheitlichen Schäden führen kann, zum sogenannten "Tennisarm". It is important that it enables the player to absorb the resulting torques without excessive force without the racket twisting in the hand. The known handle cross-sections, which closely approximate the circle, offer a rotation resistance that is far too small and are therefore only suitable to a limited extent for sports equipment of the types mentioned at the beginning. Furthermore, the cross-section of current tennis racket handles is also disadvantageous because the grip of the fingers and thumbs is insufficient. The adjacent legs of the octagon do not form good conditions for optimal grip due to the obtuse angle they enclose, since the octagon is too close to the circle. Therefore, in order to be able to be held securely, the handle has to be gripped more positively than positively, which is tired and can lead to health damage if the sport is exercised frequently and intensively, the so-called "tennis elbow".
In Zusammenhang mit dem recht häufig auftretenden Tennisarmproblem sei schliesslich noch auf die Bedeutung der Schlagdampfung hingewiesen. Da der Griff moderner Tennisschläger eine relativ grosse Querschnittsbreite aufweist (quer zur Schlagflächenebene) und zudem für den doppelhändigen Rüchhandschlag ausgelegt, also sehr lang ist, kann er praktisch keinen Beitrag zur Schlagdämpfung leisten. Die Dämpfungszone beschränkt sich auf den Schaftbereich, d. h. auf den kürzen Teil zwischen Griff und Schlägerkopf. Entsprechend gross ist daher die Belastung der Armmuskulatur, insbesondere bei hoher Schlagkadenz und grossem Krafteinsatz. Finally, in connection with the quite common tennis elbow problem, the importance of shock absorption should be pointed out. Since the handle of modern tennis racquets has a relatively large cross-sectional width (across the face of the club face) and is also designed for double-handed shooting, so it is very long, it can make practically no contribution to shock absorption. The damping zone is limited to the shaft area, i.e. H. on the short part between the handle and the club head. The load on the arm muscles is therefore correspondingly high, especially with high impact cadence and great physical exertion.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Handgriff der eingagns erwähnten Art zu schaffen, der die aufgeführten Nachteile eliminiert und dennoch allen Anforderungen gerecht wird. Insbesondere soll er ein sicheres Positionieren der Schlagfläche des Schlägers aufgrund rein sensomotorischer Informationen ermöglichen, einen hohen Widerstand gegen die am Griff auftretenden Drehmomente aufweisen und gleichzietig den für kräftiges Schlagen unerlässlichen Faustschluss gewährleisten. Ferner soll er so ausgebildet sein, dass der Griffbereich des Schlägers armschonende Dämpfungsfunktion übernehmen kann. The present invention is therefore based on the object to provide a handle of the type mentioned above, which eliminates the disadvantages listed and yet meets all requirements. In particular, it should enable the club's face to be positioned securely on the basis of purely sensorimotor information, have a high resistance to the torques occurring on the handle and at the same time ensure that the punch is essential for vigorous hitting. Furthermore, it should be designed so that the grip area of the racket can take over an arm-protecting damping function.
Erfindungsgemäss wird diese Aufgabe durch einen Handgriff gelöst, wie er im Patentanspruch 1 definiert ist. According to the invention, this object is achieved by a handle as defined in claim 1.
Durch eine solche Gestaltung wird eine sensomotorisch problemlos wahrnehmbare eindeutige Lage des Handgriffes in der Hand und damit der Schlagfläche gegenüber der Stellung der Hand, geschaffen und ein grosser Verdrehungswiderstand erzeugt, was dazu führt, dass der Schläger mit weniger Kraft umklammert werden muss, als bisher üblich und demnach weitgehend von Verdrehungen verschont bleibt. Zudem ist eine wesentlich verbesserte Lagekontrolle des Schlägers aufgrund der sensomotorischen Eindrücke. aus der Hand gewährleistet. Die ausgeprägten Kanten des erfindungsgemässen Handgriffs sind derart angeordnet, dass sie sich bezüglich Kraft - und Formschlüssigkeit optimal in die skelettbedingten Artikulationen der Hand einfügen. Die Verwendung eines Schlägers mit erfindungsgemässem Handgriff führt demnach zu weniger Ermüdung und geringerer Schweissbildung. Da die letzten Glieder der zwei grossen Finger einerseits und der Daumen andererseits diesen Handgriff optimal umklammern können, wird eine mehr formschlüssige als rein kraftschlüssige Verbindung zwischen der Hand und dem Handgriff ermöglicht, was dazu führt, dass auch grosse sich ergebende Drehmomente um die Handg r iffm i ttel achs e herum durch die Hand aufgefangen werden können, ohne dass sich der Handgriff gegenüber der Hand verdreht. Der hintere Bereich des erfindungsgemässen Griffes ist so ausgebildet, dass ein optimaler Faustschluss gewährleistet ist, d. h. die Handhöhle bei geballter Faust ist vollständig abgestützt, was von grosser Wichtigkeit ist für das Ausführen von kraftvollen Schlägen. Dieser Faustschluss ist auch bei Griffwechsel, z. B. von Vorhand- zu Rückhandgriff unverändert erhalten. Die geringe Querschnillsbreite im Hauptbereich des erfindungsgemässen Handgriffes verlängert die Dämpfungszone des Schlägerschaftes beträchtlich, womit die Gefahr des Tennisarmsymptomes reduziert werden kann. Such a design creates a clear position of the handle in the hand, and thus the striking surface in relation to the position of the hand, which can be easily sensed by the sensor motor and creates a high resistance to rotation, which means that the racket has to be clutched with less force than was previously the case and therefore largely spared from twists. In addition, there is a significantly improved position control of the racket due to the sensorimotor impressions. guaranteed from the hand. The pronounced edges of the handle according to the invention are arranged in such a way that they fit optimally into the skeletal articulations of the hand with regard to non-positive and positive locking. The use of a racket with a handle according to the invention therefore leads to less fatigue and less sweating. Since the last limbs of the two large fingers on the one hand and the thumb on the other hand can optimally clasp this handle, a more form-fitting than purely force-locking connection between the hand and the handle is made possible, which means that even large resulting torques around the handle iffm can be caught around the axis by the hand without the handle twisting relative to the hand. The rear area of the handle according to the invention is designed in such a way that an optimal fist closure is guaranteed, ie the hand cavity with a clenched fist is completely supported, which is of great size It is important for performing powerful blows. This clasp is also when changing handles, z. B. received unchanged from forehand to backhand. The small cross-sectional width in the main area of the handle according to the invention considerably extends the damping zone of the racket shaft, whereby the risk of the tennis elbow symptom can be reduced.
Der erf indungsgemasse Handgriff ist sozusagen in zwei Zonen geteilt, in die Faustschlusszone im hintern sowie die Steuer und Dämpfungszone im vorderen Bereich. The handle according to the invention is, so to speak, divided into two zones, the fist zone in the rear and the steering and damping zone in the front area.
