  • Patent number: 6692368
    Abstract: An infant's swing is disclosed. The swing is driven by an electric power to automatically operate the swing. The frame is A-shaped in a side view, and a pair of oscillation shafts are secured to a pair of securing bars respectively, the securing bars being installed in the peak portions of the frame 12 respectively. A pair of magnet boxes are provided to contain a pair of securing bars and a pair of electromagnets in each of them, and an oscillator is disposed between each pair of the electromagnets. An electric power is supplied alternately to the electromagnets to alternately magnetize them, thereby making the oscillators swing leftward and rightward.
