Abstract
A ball-striking sole for a table tennis paddle comprises a flexible coating (118) of elastic material, one face (135) of which is lined with elastically deformable pimples (120) which protrude from said face. The cross section of said pimples is greater in their region (122) of attachment to this coating than in the region close to their opposite end (124) and the side wall (125) of these pimples has a concave curved profile over at least a part of the height of the pimple between these two regions. This sole is used particularly successfully in a table tennis paddle in which the face of said sole (112) lined with pimples (120) is directed towards the inner side of the blade (115) of the paddle such that the free ends (124) of the pimples, the lateral surface of which has a concave curved profile (125), are pressed against a layer (126) of elastic material, secured to the blade, the modulus of elasticity of which is much lower than that of the elastic coating (118) of the sole. The smooth face (115-1) of the sole on the opposite side from the pimples (120) forms the striking surface of the paddle.
