- Particularly advantageous properties result for a racket that both has a front and a rear damping element.
- rackets according to the invention Suitable for tennis, squash, badminton and other rackets for ball sports.
- rackets according to the invention are made of wood, metal, metal alloys, Plastic, carbon fiber composite material, fiber materials, composite materials and Combinations can be made from it.
- the invention further provides a method for producing a ball game racket with a frame having a handle section and in particular one Ball game racket according to the preferred described above Embodiments ready.
- a preferred method has the following steps. First done the layering of several layers of a material to form the frame of the Racket, wherein at least one layer of a in the grip portion of the racket Damping properties material to form the rear Damping element is placed between and / or around the material layers. Furthermore, the multi-layer structure thus created is inserted into a mold and then molded and solidified. Then remove the Ball game racket out of shape. Then the front one Damping element arranged on the racket. In a further step, further the grip shell is arranged in the grip section of the racket.
- the Frame by layering one or more layers of a material, insert this into a shape and then shaping and solidifying the structure, manufactured. After forming the frame become the front one Damping element, the rear damping element and / or the grip shell in Handle portion of the frame arranged.
- the attachment of the damping device or the damping elements on Rackets can be done in different ways. So they can Damping elements can be designed such that they are applied to the Frame need to be stretched and after being applied due to the elastic deformation are held by internal forces on the racket. This Fastening method is preferably used in the one-piece, the racket embodiment of the damping elements applied.
- the damping elements can still be glued to the frame or be fastened to it by mechanical fastening elements.
- the front and / or the rear damping element is connected to the handle shell this attached.
- the front and rear damping elements do not have to be attached the same way.
- the front and / or the rear Damping element both on the frame of the ball game racket and on the Handle shell attached.
- the damping elements are only by the handle and / or held by a grip tape wrapped around the grip portion.
- a ball game racket according to the invention guarantees one compared to those in the state rackets known in the art improved vibration or Damping behavior, especially with bending vibrations and on especially with their first mode.
- a racket according to the invention enables thus an improved absorption of the shock shock and exhibits improved Game features on. The player is thus a safer and easier Game allows, while further reducing the risk of injury.
- a ball game racket with the damping device according to the invention has also surprisingly about a particularly advantageous and for the player pleasant damping characteristics, is very easy to handle and low vibration. Furthermore, the damping device is simple, what the Keeps manufacturing costs low. The damping device can be installed accomplish in a simple way.
