  • Patent number: 5438972
    Abstract: A washer shaped magnetic missile is combined with a launcher having a probe which supports the missile by extending through its aperture. The washer and launcher magnetically couple but relatively weakly so that deceleration of a travelling launcher will release the missile, off the probe toward a target. The forward face of the missile may be adapted for magnetic, or other couple to a target. There is also shown a flimsy target which may cling to a ferromagnetic surface for use with the missile.

  • Patent number: 5247920
    Abstract: A toy bow has a frame with a central aperture for a captive arrow shank and a rearwardly facing central space. An elastomeric string extends between standards and the arrow shank is apertured to receive the bow string. The arrow head is of magnetic material for cooperation with a missile also of magnetic material, these members providing mutual magnetic force to hold the missile on the arrowhead until released by the arrow's deceleration after forward movement. Preferably parts of the bow interfere with the forward excursion of the bow string to decrease the forward excursion of the arrow.
