ABSTRACT:
A catapult toy includes a base plate, a mounting platform swivelably mounted on the base plate, a pair of arches positioned in a side-by-side relationship on the mounting platform at one end thereof to define an arching guide therebetween, a pivot arm pivotally mounted between the arches to move generally in a vertical plane in the arching guide, a cup disposed on the free end of the pivot arm for carrying a projectile, and a stop element attachable to the arches to bridge the arching guide at various locations therealong and thereby serve to stop upward movement of the pivot arm. Also included are a pair of upright standards mounted on the mounting platform on each side of the vertical plane in which the pivot arm moves, and an elastic band mounted on the upright standards to extend therebetween underneath the pivot arm. Finally, a latch is provided to hold the pivot arm in a latched position in which the arm is stretching or biasing the elastic band. The latch is operable to release the pivot arm so that the elastic band causes the pivot arm to move upwardly until it contacts the stop element at which time the projectile carried by the cup is thrown out of the cup.
