ABSTRACT:
A catapult device for hurling objects towards a target includes a support structure and a pivot bracket pivotally mounted on the support structure and provided with a bearing arrangement. A lever arm is pivotally connected to the support structure and is engageable with the pivot bracket. A spring-biased motion translation arrangement is coupled to the lever arm and is engageable with the bearing arrangement on the pivot bracket. A pivot arm is pivotally secured to the support structure and the motion translation arrangement. The pivot arm is provided with a receiver for holding an object to be hurled. Pivotal movement of the lever arm develops a spring force in the motion translation arrangement and enables the pivot bracket to pivot such that the motion translation arrangement moves along the bearing arrangement, and releases the spring force causing the pivot arm to swing and hurl the object.
