<p>An elastic toy ball (1) made up of a plurality of curved surfaces, the contour of which is defined by four convex spherical surfaces (21, 22, 23, 24) or four small spheres of equal or different radius, a plurality of concave curved surfaces (3a, 3b, 3c, 3d) connecting the four convex spherical surfaces and six saddle portions (41, 42, 43, 44, 45, 46). The elastic toy ball of a peculiar shape according to the present invention has the various advantages as follows: (1) the ball can be caught by one hand of a little children because of the presence of the concave surfaces, (2) the ball does not roll on excessively because of its peculiar shape, (3) the ball rotates or bounds in various directions at random because of its peculiar shape, (4) the ball can be used as sport goods for an old person or as rehabilitation apparatus for a physically-handicapped person, (5) the ball can be used as building blocks.</p> |
