Abstract

A portable basketball retrieval and return device includes a movable support platform having casters for allowing the positioning of the device on a playing surface adjacent a basketball backboard and rim, a slidable upright frame mounted to the platform and to which a plurality of telescoping arms are attached whereby both the frame and arms are selectively extensible and retractable for disposing netting material which collects shot basketballs from the basketball backboard and rim. In order to eject basketballs in varying directions and velocities, and within various selected time intervals, to players dispersed about the playing surface, the device includes a catapult arm that receives basketballs and pivots between cocked and ejection positions for throwing the basketballs, a cam powered by a main thrower motor for rotating a loading wheel whose rotation lowers the catapult arm to the cocked position and a selectively pivotable positioner plate upon which the drive motor, the catapult arm, the cam, and the wheel are mounted. The device also includes an electronic control system whereby the practicing player can set the ejection points during pivotable motion of the positioner plate, the distance and velocity for the ejected basketballs, and the time interval between successive basketball ejections.

Claims

1. A portable basketball retrieval and automatic return device for use on a playing surface, comprising:

a normally-stationary portable platform for disposition on the playing surface;

a substantially closed housing mounted to rotate on the platform and having a first opening facing generally upwardly for receiving successive basketballs therethrough, and a second opening facing generally outward from a side of the housing for the ejection of the successive basketballs in a trajectory over the playing surface;

means enclosed within the housing for diverting outwardly through the second opening the successive basketballs received through the first opening including a catapult arm mounted to pivot between a first cocked position and a second released position, and a rotatable cam operatively engaged to the catapult arm to cause the arm to pivot between the first cocked position and the second released position.

2. The device of claim 1 further comprising a first main thrower motor for rotating the cam and a second positioner motor mounted to the platform for selectively pivoting the housing.

3. The device of claim 2 further comprising a positioner plate mounted on the platform and capable of selective pivotable movement on a vertical axis with respect to the housing.

4. The device of claim 3 further comprising a linkage means operatively connected to the positioner motor and the positioner plate so that selective rotary motion can be transmitted by the positioner motor through the linkage means and to the positioner plate.

5. The device of claim 4 wherein the catapult arm includes a pair of catapult arm uprights mounted to the positioner plate and extending upwardly therefrom toward the first opening and on which the catapult arm pivots.

6. The device of claim 5 wherein the catapult arm includes a seating ring for receiving thereon one basketball at a time whereupon pivotable movement of the catapult arm from the cocked position to the released position causes the basketball to be ejected from the seating ring and thrown through the second opening.

7. The device of claim 6 wherein the positioner plate is capable of selective pivotable movement within an angular range between 0°

and 180°

relative to the platform.

8. For use in combination with a basketball backboard and rim, a portable basketball retrieval and automatic return device for disposition on a playing surface beneath the backboard and rim, comprising:

a support platform capable of being positioned and repositioned on the playing surface;

a housing mounted to the support platform for selective sequential and continuous back-and-forth pivotable movement on a vertical axis within a substantially wide angular range in order to eject basketballs therefrom coincident with the pivotable movement of the housing;

funneling means mounted to the platform for selective extension and retraction thereon so that the funneling means can be disposed about the basketball backboard and rim for collecting shot basketballs and directing the basketballs downwardly to the housing so that the basketballs can be ejected therefrom about the playing surface;

the housing having an upper opening for receiving basketballs from the funneling means and an ejection aperture through which the succession of basketballs are ejected to the practicing players; and

the housing enclosing;

a basketball thrower means including a catapult arm disposed beneath the upper opening for successively receiving basketballs that fall through the upper opening, the catapult arm selectively pivotable between a cocked position and a released position in order to continuously throw basketballs through the ejection aperture;

variable basketball distribution means mounted to the platform for pivoting the housing within the predetermined angular range including a positioner plate pivotably mounted to the platform and to which the housing is secured, a positioner motor mounted to the platform, linkage means operatively engaging the motor to the positioner plate for transmitting selective pivotable motion to the positioner plate;

a basketball ejection means mounted to the positioner plate and including a main thrower motor, and a cam operatively engaged by the main thrower motor for selective unidirectional rotation to cock and release the catapult arm; and

the basketball thrower means and the basketball ejection means both being mounted to the positioner plate so that the basketball thrower means and the basketball ejection means pivot concomitant with the pivotable motion of the housing.

9. The device of claim 8 further including spring means operatively connected to the catapult arm and responsive to rotation of the cam to apply a biasing force to urge the catapult arm toward the released position.

10. The device of claim 9 wherein the spring means includes a pair of spaced-apart springs that are selectively biased from a loaded position for cocking the catapult arm to a released position for pivoting the catapult arm to throw the basketball.

11. The device of claim 10 wherein the positioner plate is capable of selective pivotable movement throughout the angular range whereupon the positioner plate can momentarily stop at a series of predetermined positions to throw the basketball and then continue pivoting to the next position to throw the next basketball.

12. The device of claim 11 further comprising a means to selectively vary the number of sequential positions from which the basketballs can be thrown during pivotable movement of the housing throughout the angular range.

13. The device of claim 12 wherein the means to vary the number of sequential positions to throw the basketball includes at least one proximity switch mounted to the catapult arm upright adjacent the catapult arm and which is capable of selective upward and downward adjustment on the catapult arm with respect to the pivot point of the catapult arm.
