  • the junior version is not shorter than the shortest women's adult tennis racket, has a minimum weight of 250 g, an inner frame area corresponding to an adult midsize tennis racket, string spacing in the sweet spot area corresponding to the string spacing in the sweet spot area of the adult tennis racket, and the balance point more than 1 cm inside the frame.
  • the extreme grip heaviness not only makes handling much more difficult, it also makes the children's tennis racket subjectively appear much heavier than it is.

  • the invention has for its object to provide a children's tennis racket that corresponds to the physical and physiological properties of the child and significantly facilitates the learning of the tennis game for children, and to create a children's tennis learning system with which the children learn the tennis game with as much as possible many and strong experiences of success quickly get past the initial threshold that previously required an unjustified selection.
  • the extremely lightweight, child-friendly and specially balanced children's tennis racket may still be a little heavier for a child than a modern adult tennis racket for an adult. Nevertheless, it turns out surprisingly that the children get along well with such child tennis rackets that are deliberately designed and designed for children and learn quickly to hit the balls, play the balls over the net, and are able to do so in a very short time, at least To play ball changes with the trainer and possibly even with other children because the weight disadvantage is largely absent and the balance is right, so that the children have intense and frequent successes that are fun and enjoyable for them when they learn the game of tennis and that they support the natural play instinct.
  • the children's tennis racket with the weight reduced to a maximum of 180 g compared to the previously available children's tennis rackets, the enlarged inner frame area of at least 600 cm 2 corresponding to at least the inner frame area of an adult oversize tennis racket and with string spacings of at least 18 mm in the sweet spot area is the first time a child-friendly tennis racket that makes handling considerably easier for children.
  • the children's tennis rackets are also child-friendly and can be played successfully if the string spacing in the sweet spot area is less than 18 mm.
  • the large frame inner surface creates an extra large striking surface with a large sweet spot area, so that balls can be controlled even if they are not hit cleanly.
  • the large string spacing at least in the sweet spot area, leads to a desirable trampoline requirement. perfect and reduces the string mass, whereby the string tension can also be low for children. Although this is not absolutely necessary, softer and / or larger children's tennis balls or corresponding foam balls should be played with such children's tennis racquets, because these make it easier for the children to learn the tennis game quickly, well and above all with joy.
  • the well-known tennis learning system with cross markings that can be moved on a standard playing field at a distance from the network, with which the learning children are gradually guided from the service fields to and finally to the baseline, leads to unexpectedly rapid learning progress when using children's tennis rackets be that weigh a maximum of 180 g, have a very large frame inner surface and a string spacing at least in the sweet spot area of at least 18 mm, and where the balance point max. 1 cm inside the face or closer to the end of the handle. Excellent learning progress can already be achieved when the children's tennis rackets are better balanced than conventional children's tennis rackets and, thanks to their lightweight construction, weigh no more than 180 g.
  • At least three categories of children's tennis racket are useful for e.g. three groups of children: these are beginners between the ages of 3 and 5 years, beginners between the ages of 5 and 7 years, and advanced students between the ages of around 6 and 7 years.
  • the little ones or the youngest play with the stubby club which is not only extremely light and very short, but also has an extremely large playing surface with a pronounced trampoline effect.

  • the string spacings are at least 18 mm at least in the sweet spot area.
  • the relatively rough string grid in String bed results in a pronounced trampoline effect and, of course, despite the large face, in a significantly reduced string mass, whereby the string tension can be chosen to be relatively low.
  • the string spacing can also be narrower than 18 mm.
  • the balance point is at most 1, 0 cm in the inner frame area or behind.
  • the balance point of the stub version could even be up to 2.0 cm in the inner surface of the frame, and the racket would still be much better to play than known stub versions due to the low weight, in which the balance point is set up to 5 cm and more inside is. Regardless of how far the balance point is in the inner surface of the frame, the stub version is in any case better balanced than known stub versions due to the lightweight construction.
  • the short version is suitable for children, for example for 5- to 7-year-old beginners. It weighs a maximum of 160 g, rather only 170 to 140 g, and has a striking area of at least 600 cm 2 .
  • the balance point may lie at the most in the bridge of the racket heart, better further to the end of the grip, so that the racket is well balanced. In the short version, however, the balance point can also lie slightly within the face, so that the short version is better balanced than known short versions thanks to the lightweight design.
  • the junior version for example, is around 63.8 cm long and is particularly suitable for advanced students aged between 6 and 7 years. Thanks to the center of gravity or balance point optimally placed behind the bridge, the feeling when playing is that the weight is almost only half the weight of a junior tennis racket known for this age and skill level group.
  • This low weight, the significantly larger playing surface for example, roughly corresponds to the playing surface of an adult oversize tennis racket, and the large string spacing, at least in the sweet spot area, means that children in this group of children not only quickly play well, but also hit hard.
  • the balance point could also be slightly within the frame area.
  • the string spacing in the sweet spot area could also be less than 18 mm.

  • the lightweight design of the new children's tennis racket means that the conventional construction of children's tennis rackets has been abandoned.
  • the frame is either made using only high-strength fiber materials such as carbon or aramid fibers, possibly in specially designed forms.

  • the lightweight frame can also be formed from a light metal hollow profile, preferably with frame dimensions that are only half to a third of the frame dimensions of adult light metal tennis rackets.
  • the lightweight construction reduces weight and optimizes the position of the balance point.
  • Another important feature is a handle with a minimum handle length corresponding to two children's hands, on the one hand, to be able to teach children to play with two hands, on the other hand, to enable the often instinctively chosen two-hand grip without any problems. It is important that the grip extends as close as possible to the face, at least in the stub version, because children initially tend to grip as shortly as possible.

  • the learning progress is particularly successful if the learning system uses the movable cross markings, the extremely light and balanced children's tennis rackets and balls suitable for children, ie larger foam balls or larger or lighter or softer children's tennis balls.
  • Successful should mean that the children not only get over the initial threshold faster but that more children who are curious about tennis will remain loyal to tennis later than before, which means that far fewer newcomers due to frustration or shame or because of parents' discontent will soon give up tennis again.
  • the tennis learning system for children which includes cross markings that can be offset from the network on a standard playing field, children's tennis rackets, and child-friendly tennis balls that are softer than standard tennis balls is particularly effective if stub versions, short versions and, depending on the body size and / or playing strength, are assigned to the children Junior versions of children's tennis rackets with a weight including stringing of a maximum of 180 g combined with differently soft tennis balls can be provided.
