ABSTRACT:
A hand catapult for throwing flying discs such as a Frisbee.TM. or a Flying Saucer.TM. is constructed with a yoke pivotally connected to a handle for a movement through an angle of not more than about 45 degrees to each side of the center line of the device. The yoke comprises an inner circumferentially channeled semicircular portion conforming to and adapted to receive the disc and having a long complementarily channeled arm projecting tangentially from one terminus of the semicircular portion and a short complementarily channeled arm projecting from the other terminus of the semicircular portion. The yoke is constructed of semirigid plastic material and the short arm extends beyond the semicircular portion a distance just sufficient to offer a slight resistance to the insertion and withdrawal of the disc in the channeled semicircular portion. The device is biased to the uncocked position and is provided with a pressure-releasable device for holding the yoke in the cocked position against said bias device. The pressure-releasable device is adjusted to be released by the pressure engendered thereon by the tendency of the yoke to rotate toward the uncocked position when it is swung in an arc by the person grasping the handle.
