A basketball goal apparatus has a basketball goal and an upright stand. The apparatus also includes a support assembly for supporting the goal on the stand at various heights spaced from the ground. The support assembly includes an elongated support member attached medially along the length thereof to the stand for swinging movement about a generally horizontal axis. The apparatus further includes a locking assembly for releasably locking the goal at the various heights, wherein the locking assembly includes a counterbalance body. The counterbalance body and basketball goal are pivotally connected to opposite ends of the support member such that raising and lowering of the counterbalance body swings the support member and thereby adjusts the height of the goal. The counterbalance body has a weight sufficient to substantially counterbalance the gravitational force of the basketball goal exerted on the support member. The locking assembly also includes a relatively stationary body and securing mechanism for releasably securing the counterbalance body to the stationary body to selectively prevent raising and lowering the counterbalance body. |
