Collapsible batting cage system

1. An apparatus comprising:

a plurality of upright frames, an upright frame of the plurality of upright frames comprising:

a first upright segment;

a second upright segment;

a lateral segment to connect a first end of the first upright segment to a first end of the second upright segment;

a first base segment to couple to a second end of the first upright segment;

a second base segment to couple to a second end of the second upright segment, wherein the first base segment and the second base segment are to interface with a ground surface to support the upright frame in an upright position; and

a cross member to couple to the first upright segment of the upright frame and to a first upright segment of a second upright frame of the plurality of upright frames, the cross member to provide lateral stability to the upright frame and the second upright frame, the cross member comprising a side connection joint having an elbow shape, wherein the side connection joint is adapted to slide over or into a cross member coupling attached to the first upright segment;

wherein the plurality of upright frames are adapted to support a batting cage net when in use and the plurality of upright frames are nestable together or may be placed directly adjacent each other when not in use.

2. The apparatus of claim 1 , wherein the upright frames are free standing in the upright position when supported by the first and second base segments without additional lateral support.

3. The apparatus of claim 1 , wherein, when the upright frame is in the upright position, the first upright segment extends further vertically than laterally and the lateral segment extends further laterally than vertically.

4. The apparatus of claim 1 , further comprising a cross member, a first end of the cross member to couple to the first upright segment of the upright frame and to a first upright segment of a second upright frame of the plurality of upright frames, the cross member to provide lateral stability to the upright frame and the second upright frame.

5. The apparatus of claim 4 , further comprising a second cross member, a first end of the second cross member to couple to the first upright segment of the upright frame and to the first upright segment of the second upright frame, the second cross member to provide additional lateral stability to the upright frame and the second upright frame.

6. The apparatus of claim 4 , wherein the first end of the cross member is adapted to be slid in a generally vertical direction to mate with a coupling attached to the first upright segment of the upright frame and the second end of the cross member is adapted to be slid in a generally vertical direction to mate with a coupling attached to the first upright segment of the second upright frame.

7. The apparatus of claim 1 , wherein a second upright frame of the plurality of upright frames is smaller than the upright frame and a third upright frame of the plurality of upright frames is smaller than the second upright frame, such that when the plurality of upright frames are nested together, the second upright frame nests within the upright frame, and the third upright frame nests within the second upright frame.

8. The apparatus of claim 1 , further comprising a track system comprising a first track and a second track, the first track to be placed parallel to the second track, the first track and the second track to guide movement of the plurality of upright frames and to allow the plurality of upright frames to be placed together when not in use.

9. The apparatus of claim 8 , wherein the first track comprises a first rail and the second track comprises a second rail.

10. The apparatus of claim 8 , wherein the first track and second track are to be installed below a ground surface.

11. The apparatus of claim 8 , further comprising one or more locking mechanisms to lock the upright frame in place at a desired position along the first track and the second track.

12. The apparatus of claim 1 , wherein the first base segment comprises a straight edge along a portion of a bottom of the base segment, a first rising edge from the straight edge to a top of the base segment on a first side of the base segment, and a second rising edge from the straight edge to the top of the base segment on a second side of the base segment.

13. The apparatus of claim 1 , wherein the first base segment comprises one or more cleats adapted to penetrate into the ground surface when the upright frame is placed in the upright position.

14. The apparatus of claim 1 , wherein the base segment comprises at least one wheel.

15. The apparatus of claim 1 , wherein the base segment comprises a flat plate.

16. The apparatus of claim 1 , wherein the first base segment comprises a pair of legs protruding at opposite angles from the second end of the first upright segment.

17. The apparatus of claim 1 , wherein the first base segment comprises a piece of tubing for placement perpendicular to the first upright segment.

18. The apparatus of claim 1 , further comprising the batting cage net.

19. The apparatus of claim 1 , wherein the first upright segment comprises a piece of tubing, the cross member coupling is attached along a portion of a side of the piece of tubing, and the side connection joint of the cross member mates with the cross member when placed above the cross member coupling and moved downward in a generally vertical direction.
