  • Patent number: 6863588
    Abstract: A toy assembly and its method of manufacture. The toy assembly is a spherical object that can be temporarily compressed into a disc. A short time after compression, the toy pops back into its original ball-like shape. The toy assembly has shell sections that join along at least one joint line to form a generally spherical body. The shell sections are symmetrically disposed around a central axis. The spherical body is bisected by an imaginary equatorial plane that is perpendicular to the central axis. The joint lines between shell sections exist in meridian planes that are perpendicular to the equatorial plane. A connector mechanism is provided that temporarily connect opposite sides of the shell when the shell is compressed. The shell sections provide a spring bias that resists any compression and causes the shell sections to return to a spherical shape when the connector mechanism release.
