Abstract
Abstract A basketball game including a stand bearing a backboard and a net, a basketball, and a catapult. The ball fits in a cup at one end of the catapult lever. The lever pivots on a pin so that when one end of the lever is depressed the other end of the lever bearing the cup is elevated imparting upward and outward motion to the ball. An adjustable stop arm regulates the upward motion of the cup and hence the angle and height of motion of the ball, and the upward and downward position of the stop arm is adjusted by moving the arm so that a hole in a downward extending portion of the adjustable stop arm is aligned with the desired one of a series of holes in an upward extending portion of the catapult base, enabling a pin to be inserted through the aligned holes for interlocking.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
242 words
A basketball game comprising basketball goal means, a ball, and movable actuator means for projecting the ball towards the basketball goal means, said actuator means including limiter means for adjustably regulating the angle and height of projection of the ball, in which the actuator means includes a pivotally mounted lever having a ball receiving cup at one of its ends and a finger actuated key at its other end so that on depression of the key the cup is elevated to project the ball towards the goal and in which the limiter means includes a stop arm and an approximately L-shaped pivotally mounted lever having one component from which the stop arm protrudes at right angles and another component extending in a generally downward direction said stop arm limiting the upward movement of the ball receiving cup by acting against the portion of the pivotally mounted lever adjacent the ball receiving cup to prevent upward movement of that portion of the pivotally mounted lever and in which the generally downward extending component of the pivotally mounted limiter lever includes means for adjustably locking the downward extending component of the pivotally mounted limiter lever to the actuator means to provide for adjustably changing and fixing the position of the limiter means to regulate the angle and height of projection of the ball and said adjustable locking means includes structure defining a hole in the downward extending component of the pivotally mounted limiter lever.
Claim 2
Dependent Claim
242 words
A basketball game comprising basketball goal means, a ball, and movable actuator means for projecting the ball towards the basketball goal means, said actuator means including limiter means for adjustably regulating the angle and height of projection of the ball, in which the actuator means includes a pivotally mounted lever having a ball receiving cup at one of its ends and a finger actuated key at its other end so that on depression of the key the cup is elevated to project the ball towards the goal and in which the limiter means includes a stop arm and an approximately L-shaped pivotally mounted lever having one component from which the stop arm protrudes at right angles and another component extending in a generally downward direction said stop arm limiting the upward movement of the ball receiving cup by acting against the portion of the pivotally mounted lever adjacent the ball receiving cup to prevent upward movement of that portion of the pivotally mounted lever and in which the generally downward extending component of the pivotally mounted limiter lever includes means for adjustably locking the downward extending component of the pivotally mounted limiter lever to the actuator means to provide for adjustably changing and fixing the position of the limiter means to regulate the angle and height of projection of the ball and said adjustable locking means includes structure defining a hole in the downward extending component of the pivotally mounted limiter lever.
Claim 3
Dependent Claim
71 words
A basketball game as described in claim 1 in which the actuator means includes a base having an upward projecting portion and a pivot pin extending through the upward extending portion of the base near its upper extremity, the pivotally mounted ball cup bearing lever and the pivotally mounted limiter lever each being mounted on the pivot pin on opposite sides of the upward projecting portion of the actuator means base.
Claim 4
Dependent Claim
148 words
A basketball game as described in claim 2 including said hole being near the bottom extremity of the generally downward extending component of the pivotally mounted limiter lever, structure defining a series of holes in the upward extending portion of the base near its lower extremity and along the pivotal arc of the downward extending component of the pivotally mounted limiter lever, and a lock pin in which the position of the limiter means is adjustable changed to regulate the angle and height of projection of the ball by moving the stop arm to its desired position while lining up the hole in the generally downward extending component of the pivotally mounted limiter lever with the desired one of the series of holes in the upward extending portion of the base and then inserting the lock pin through the aligned holes to lock the stop arm in position.
