  • Patent number: 6666782
    Abstract: The present invention discloses a blinking spherical toy, comprising an internal sphere composed of an upper hemisphere and a lower hemisphere, and the lower hemisphere having a circuit board with a circuit connecting to at least one lamp and one battery module, and two electrode rods passing through the bottom of the lower hemisphere; an external sphere having a size larger than the internal sphere and composed of a bottom hemisphere and a top hemisphere for accommodating the internal sphere, and a contact end disposed on both sides of the bottom axial line of the bottom sphere and passing through and being exposed from the bottom hemisphere. A non-conductive liquid is injected into the external sphere to fill the space between the internal sphere and the external sphere. By means of the gravitational force of the internal sphere, its upper sphere finally faces upward, and the two electrode rods of its lower sphere touch both contact ends.

  • Patent number: 6268027
    Abstract: An improved ornament for placement includes an elastic plastic cover which is a tubular member formed from high molecular polymer material having elasticity, one end thereof being a closed end, the other end thereof being an open end, the periphery of the open end extending laterally to form an engaging ring having a substantially L-shaped cross-section; a connecting ring which is a hollow annular fixed member and has a top portion provided downwardly with a projecting ring of a substantially inverted-J cross-section at a position corresponding to the engaging ring, a lower end of the projecting ring being integrally provided with a connecting portion; an annular base which is a multi-step annular member provided respectively with an annular post and a pivotal portion at an upper end at positions corresponding to the open end and the connecting portion. The engaging ring is inserted into the projecting ring to achieve tight connection.
