| 摘要 |
This invention provides a toy ornithopter which has an elongated body and two pairs of wings at the front with a driving mechanism including a cranked drive member arranged so that the wings move in pairs in out-of-phase relation with one pair moving up as the other pair moves down. The driving mechanism includes either articulated linkages connected to the wings or a specially shaped fitment on which the wings are mounted so arranged as to cause the wings to undergo the desired motion.
