ABSTRACT:
An apparatus (10) for propelling a projectile generally vertically upward includes a Y-shaped member (12) having a shaft (14) and a pair of elongated arms (16) attached to an upper end of the shaft and extending upward therefrom in spaced-apart relation. The shaft slides telescopingly into a hollow tubular ferrule (20) attached to the top end of an elongated pole (18) and is secured within the ferrule by a spring-biased pin (30), the shaft forming an extension of the pole. The arms have upper curved portions (42) each of which curves through an angle substantially greater than 90 degrees, so that the free ends (44) of the arms define a direction that has a substantial component parallel to the pole toward the bottom end (48) thereof. A sling assembly (34) is attached via elastic tubing (38) to the arms, free ends of the tubing being sleeved over the curved portions of the arms.
