Abstract

A ball return device that enables a user to quickly and easily adjust the force with which a ball thrown into the device is returned. The ball return device includes a frame constructed from sections of plastic tubing joined by 90° elbows, forming a base and an elevatable portion. The elevatable portion of the frame is pivotally mounted to the base and adjustably positioned at a desired angle relative to the generally horizontal base by a pair of support members. The angle of the elevatable portion of the frame to the base determines the direction in which the ball is returned relative to a given incident path. The support members extend between the base and the elevatable portion of the frame, and each includes a smaller diameter tube slidably fitted into a larger diameter tube and selectively fixed at one a plurality of preset lengths by a pin that passes through orifices formed in the two tubes. In one preferred form of the invention, a net having hexagonal openings is suspended within the elevatable portion of the frame by lengths of an elastomeric cord that connect a periphery of the net to the frame. The hexagonal openings deform around a ball impacting the net in such a way as to ensure that the ball is consistently returned at a predictable angle relative to the angle at which the ball impacts the net. The elastomeric cord can be tightened or loosened to adjust the tension of the net, thereby determining the relative force with which a ball impacting the net is returned. A friction clip attached to the elastomeric cord retains the selected tension.

Claims

(a) a frame having a base portion and an elevatable portion;

(b) an elastomeric panel suspended within the elevatable portion by an elastomeric cord that extends between a periphery of the elastomeric panel and the elevatable portion of the frame, said elastomeric cord coupling the elastomeric panel to the elevatable portion of the frame so that the elastomeric panel defines an impact area for the sports projectile as the projectile travels along the incident path; and

(c) means for adjusting a tension of the elastomeric panel to enable a user to selectively change a force with which the sports projectile is deflected back along the return path relative to that at which the sports projectile traveling along the incident path strikes the elastomeric panel.

2. The apparatus of claim 1, wherein the elastomeric panel comprises a net having a plurality of hexagonal-shaped openings formed of knitted strands, said hexagonal openings conforming uniformly around the sports projectile when the net is impacted by the sports projectile so that the return path of the sports projectile is consistently predictable relative to the incident path of the sports projectile.

3. The apparatus of claim 1, wherein the frame comprises a plurality of tubing sections, at least some of which are joined by elbow connectors, said elevatable portion of the frame having a generally quadrilateral shape.

4. The apparatus of claim 3, wherein the plurality of tubing sections comprising the elevatable portion include an orifice into which a tag end of the elastomeric cord is inserted to hide any excess length of the elastomeric cord.

5. The apparatus of claim 1, wherein the elevatable portion of the frame is pivotally attached to the base portion and is selectively adjustable by the user by rotating the elevatable portion of the frame to a desired angle relative to the base portion.

6. The apparatus of claim 5, wherein the frame includes a support member that extends between the elevatable portion and the base portion, said support member having a length that is adjustable, the angle of the elevatable portion relative to the base portion being selectively varied as a function of the length to which the support member is adjusted.

7. The apparatus of claim 6, wherein said support member comprises a smaller diameter tube and a larger diameter tube, said smaller diameter tube sliding inside the larger diameter tube, further comprising a set pin that extends through an orifice in at least one of the smaller and larger diameter tubes, to fix the length of the support member.

8. The apparatus of claim 5, wherein a top of the elevatable portion of the frame can be set at a plurality of predefined angles relative to a horizontal plane, said plurality of predefined angles ranging between a first position in which the top is closer to the user than a bottom of the elevatable portion of the frame, and a second position in which the bottom of the elevatable portion of the frame is closer to the user than the top.

9. The apparatus of claim 1, wherein the elevatable portion of the frame includes a plurality of orifices through which the elastomeric cord is threaded to couple the elastomeric cord to the elevatable portion of the frame.

10. The apparatus of claim 1, wherein the means for adjusting the tension of the elastomeric panel comprise means for selectively changing a tension in the elastomeric cord.

11. The apparatus of claim 10, further comprising a clip that is releasably attached to the elastomeric cord to maintain said cord at a desired tension.

12. The apparatus of claim 1, wherein the elevatable portion of the frame includes a plurality of eyelets attached to the frame at spaced-apart intervals, said elastomeric cord being threaded through the plurality of eyelets to couple the elastomeric cord to the elevatable portion of the frame.

13. The apparatus of claim 1, wherein the elastomeric cord is repetitively looped around the elevatable portion of the frame to couple the elastomeric cord thereto.

14. The apparatus of claim 1, wherein ends of the elastomeric cord are drawn tight under tension and at least one end of the elastomeric cord is fastened in a clip to apply a desired tension to the elastomeric panel.
