Abstract

Abstract A large basket shaped framework enclosed by an outer covering is positioned beneath a basketball basket. A chute leads from the bottom of this framework to a basketball return mechanism. The return mechanism comprises a motor driven rotating projecting arm and a transfer arm for transferring a basketball from the end of the chute to the projecting arm. The projecting arm is connected to the motor by a drive shaft and a torsion spring mount. A tension spring controlled arm engages the end of the projecting arm to prevent it from rotating while the transfer arm operates. When the force in the torsion spring increases to a force greater than that of the tension spring, due to the continued operation of the motor, the projecting arm is released and throws the basketball resting thereon to a user.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 272 words
A portable and automatic basketball retrieval and return device for use in the practice of the sport of basketball with a conventional basketball goal and conventional basketballs which comprises, in combination: a. a ball retrieval system comprising a base portion having a plurality of tubular members to form an upstanding frame attached to and extending therefrom, an outer covering attached to said frame whereby an enlarged upward opening is provided for the capture of a basketball and whereby said covering converges downwardly to guide the ball toward an opening in the lowest portion thereof; b. a ball return system; c. means for transferring a basketball from said ball retrieval system to said ball return system wherein said ball return system comprises: d. a housing, e. a reduction gear motor associated with said housing, f. a drive shaft driven by said motor, g. a basketball projectile arm, h. means for imparting rotational movement from said drive shaft to said basketball projectile arm, i. means for transferring a basketball to said projectile arm, j. tension means for momentarily halting rotational movement of said projectile arm, k. means for overcoming tension applied to said projectile arm wherein said means for overcoming tension comprises: l. at least one projectile spring mounted in said projectile arm wherein said reduction gear motor continues to drive said drive shaft, wherein rotational movement is thereby imparted from said drive shaft to said basketball projectile arm after said projectile arm has been retained momentarily by said tension means whereby said tension means is overcome by force of said reduction gear motor thereby providing the force required to activate said projectile arm.
Claim 2
Dependent Claim 272 words
A portable and automatic basketball retrieval and return device for use in the practice of the sport of basketball with a conventional basketball goal and conventional basketballs which comprises, in combination: a. a ball retrieval system comprising a base portion having a plurality of tubular members to form an upstanding frame attached to and extending therefrom, an outer covering attached to said frame whereby an enlarged upward opening is provided for the capture of a basketball and whereby said covering converges downwardly to guide the ball toward an opening in the lowest portion thereof; b. a ball return system; c. means for transferring a basketball from said ball retrieval system to said ball return system wherein said ball return system comprises: d. a housing, e. a reduction gear motor associated with said housing, f. a drive shaft driven by said motor, g. a basketball projectile arm, h. means for imparting rotational movement from said drive shaft to said basketball projectile arm, i. means for transferring a basketball to said projectile arm, j. tension means for momentarily halting rotational movement of said projectile arm, k. means for overcoming tension applied to said projectile arm wherein said means for overcoming tension comprises: l. at least one projectile spring mounted in said projectile arm wherein said reduction gear motor continues to drive said drive shaft, wherein rotational movement is thereby imparted from said drive shaft to said basketball projectile arm after said projectile arm has been retained momentarily by said tension means whereby said tension means is overcome by force of said reduction gear motor thereby providing the force required to activate said projectile arm.
Claim 3
Dependent Claim 67 words
A basketball retrieval and return device as recited in claim 1 wherein the means for transferring a basketball from the ball retrieval system to the ball return system comprises a chute having an elevated portion mounted directly beneath said ball retrieval system whereby the basketball can roll by force of gravity to a lower portion of the chute whereupon entrance is made to the ball return system.
Claim 4
Dependent Claim 50 words
A basketball retrieval and return device as recited in claim 1 wherein said tension means for halting rotational movement of said projectile arm consists of a holding spring attached to a pivotally mounted pressure stop whereby tension is applied thereto whereby said projectile arm is momentarily halted from rotational movement.
Claim 5
Dependent Claim 25 words
A basketball retrieval and return attached as recited in claim 3 further comprising a turnbuckle attahced to said holding spring for adjusting the tension thereof.
Claim 6
Dependent Claim 51 words
A basketball retrieval and return device as recited in claim 1 wherein said means for transferring a basketball to said projectile arm comprises a pivotally mounted loading arm and means interconnecting said drive shaft to said loading arm thereby converting rotary motion of the former to pivotal movement of the latter.
Claim 7
Dependent Claim 44 words
A basketball retrieval and return device as recited in claim 5 wherein said interconnecting means comprises a vertical member provided with a slot therein to provide a time delay for movement of the ball to said loading arm during activation of said loading arm.
Claim 8
Dependent Claim 48 words
A basketball retrieval and return device as recited in claim 5 further comprising a pivotally mounted loading ramp interconnected to said loading arm whereby said loading ramp can sequentially and intermittantly retain a ball until said projectile arm is activated, thereby forcefully projecting the ball to the shooter.
