Abstract
A table tennis racket includes a rubber (4) attached onto a blade (3) and easily removable without releasing any air-polluting gas. Opposing surfaces of the blade (3) and the rubber (4) have fine pores and lands of a micro-foam material, and the rubber (4) is removably held on the blade (3) with a vacuum suction force produced between the blade (3) and rubber (4) when pressed together.
Claims8
A table tennis racket including a blade and a rubber attached to the blade, characterized in that:
- the rubber includes a bottom surface for contact with the blade, said bottom surface being composed of a porous surface of a first micro-foam material having numerous fine pores and lands,
- the blade includes at least one major surface for contact with the rubber, said major surface being composed of one of a smooth surface and a porous surface of a second micro-foam material having numerous fine pores and lands, and
- the rubber is removably held on said major surface of the blade by a vacuum suction force produced between the bottom surface thereof and said major surface of the blade by pressing the rubber onto the blade to evacuate the numerous fine pores.
A table tennis racket including a blade and a rubber attached to the blade, characterized in that:
- the rubber includes a bottom surface for contact with the blade, said bottom surface being composed of a smooth surface of a film or a coating,
- the blade includes at least one major surface for contact with the rubber, said major surface being composed of a porous surface of a micro-foam material having numerous fine pores and lands, and
