[Problem] A ball is provided which bounces even if compressed air above atmospheric pressure is not blown into the inside of the ball. [Solution] On inner wall surfaces of a plurality of divisional bodies 1 and 11 configured of a soft material made of resin or rubber, many recessed parts 4 and 14 are formed as being surrounded by many linear protruding parts 3 and 13 to form triangles or shapes in a geometric pattern other than triangles. With this, the protruding parts exert a function equivalent to that as a bobbin to make a ball have uniform hardness as a whole, allowing user as a ball irrespectively of attaching a skin body formed separately from the plurality of divisional bodies 1 and 11 to an outer wall surface of the ball. On the other hand, divisional end parts of the divisional bodies 1 and 11 forming circular openings or flange parts 5 and 15 provided to the divisional end parts are welded or bonded together, and do not protrude outside from the outer wall surface of the ball, thereby allowing use at ease as a ball irrespectively of attaching a skin body. |

A hollow rubber play ball is disclosed that uses a combination two or more fillers to produce desirable playing properties in a tennis ball as specified by the International Lawn Tennis Federation (ITF). The preferred play ball is a pressureless tennis ball. The specific fillers disclosed are mineral type particulate reinforcing fillers such as silicas and carbon black, polymeric fillers such as cellulose, a reaction product of grafting polyethylene with cellulose, and ethylene-vinyl acetate copolymers. These fillers can also have surface treatments to enhance the elastomer-filler interaction. Another reinforcing filler that can be introduced with the rubber components is the non-rubber constituents in skim rubber that serve to increase the modulus of a compounded rubber. |

An indoor golf game including a hole layout area (11) enclosed by netting (20, 21, 23) and a substantially planar rigid or solid rebound surface (19). A ball is hit from a tee (13) in the hole layout area towards the rebound surface so as to rebound therefrom towards a hole (18) in the green area (17) of the hole layout. The ball (26, 31) used in the game comprises a ball having a hard surface so as to provide the feel of a standard golf ball but a resilience substantially less than a standard golf ball so that the ball resiliently deforms and loses substantial kinetic energy upon striking the rebound surface (19). | ||||||

L'invention se rapporte à un jeu d'intérieur s'apparentant au golf, qui comprend une surface de parcours d'un trou (11) délimitée par de filets (20, 21, 23) et une surface de rebond rigide ou solide sensiblement plane (19). Le joueur frappe une balle à partir d'un tee (13) ou point de départ situé dans la surface de parcours du trou en direction de la surface de rebond, pour que celle-ci rebondisse contre cette surface et revienne vers un trou (18) ménagé dans la zone du green (17) de la surface de parcours du trou. La balle (26, 31) utilisée pour ce jeu se compose d'une balle présentant une surface dure qui donne au joueur la même sensation qu'une balle de golf standard, mais sa résilience est sensiblement inférieure à celle d'une balle de golf standard, de sorte qu'elle se déforme élastiquement et perd une majeure partie de sont énergie cinétique en heurtant la surface de rebond (19). | ||||||
