Abstract
Description
[0001] Technical field: The invention relates to a rubber for table tennis rackets, consisting of a top rubber and an underlying sponge.
[0002] State of the art: Conventional sponges consist of a homogeneous layer. These offer either a lot of control (soft) or a lot of speed (hard), but rarely both optimally in one surface.
[0003] Objective of the invention: To create a coating that dynamically adapts its catapult behavior to the impact force.
[0004] Solution: This is achieved by a sponge consisting of several superimposed individual layers with different physical properties (hardness and / or density), the sponge preferably being composed of five to nine individual layers.
[0005] Advantage: In passive strokes, the outer layers dampen the impact, while in hard attack strokes, the deeper layers provide maximum acceleration.
[0006] Brief description of the drawing: Fig. Figure 1 schematically shows a table tennis rubber with a top sheet (1) and a multi-layered sponge structure (2 to 8) arranged underneath. In the illustrated embodiment, the sponge structure has seven individual layers. However, the number of individual layers can vary and is preferably in the range of five to nine.
Claims
[1] Table tennis rubber consisting of a top rubber and a sponge, characterized by that the sponge consists of at least five superimposed individual layers of elastic material. [2] Table tennis rubber according to claim 1, characterized by that the individual layers have a hardness and / or density that varies from the outside to the inside. [3] Table tennis rubber according to claim 1 or 2, characterized by , that the layers are arranged in such a way that a different number of layers are activated to return force depending on the impact energy of the ball. [4] Table tennis rubber according to any one of the preceding claims, characterized by that the sponge is preferably composed of five to nine individual layers.
