Abstract

The present invention is a telescoping plyometric exercise device which can be rapidly adjusted for height using a single lifting motion. The apparatus is incrementally height-adjusted and secured in a position capable of withstanding force. The apparatus requires a single lifting motion to securely and incrementally adjust the device, and to balance impact and force through the use of novel, contoured inner components and structural assemblies. These inner components and structural assemblies are engineered to provide the capability for rapid height adjustment of the apparatus.

Claims

1. A plyometric device comprised of:

at least one outer four-sided structure and at least one inner four-sided structure wherein said outer four-sided structure and said inner four-sided structure are telescoping;

at least one rod having a cylindrical face;

wherein at least a first side and a second side of said inner structure have at least one slot having a diameter equal to or larger than said cylindrical face of at least one rod;

wherein at least two sides of said outer four-sided structure have a plurality of circular contours , wherein said circular contours are adjoined by a straight segmented contour and wherein said straight segmented contour is down-ward sloping;

wherein said series of contours begins at an angled upper surface and ends at an angled lower surface;

wherein said semi-circular contours have a radius equal to or larger than said cylindrical face of at least one rod; and

wherein each of said downward sloping contours have a uniform angle between twenty and seventy degrees to guide said one rod in an upward and laterally outward direction.

2. The device of claim 1, wherein each at least one slot comprises at least a first region, a second region, and a third region, wherein said regions are contiguous and wherein said first region underlies said semi-circular contours.

3. The device of claim 2, wherein the position of said rod within said first region and said semi-circular contours operate as a stop to prevent downward movement of said outer structure relative to said inner structure.

4. The device of claim 2, wherein said downward sloping contours exert a physical pressure on said at least one rod into said second region when said outer structure is raised.

5. The device of claim 4, wherein said second region is smoothly continuous with said first region such that said at least one rod freely slides from said second region to said first region when said outer structure is lowered.

6. The device of claim 2, wherein said downward sloping contours push said rod into said third region when said outer structure is raised beyond a maximum point.

7. The device of claim 2, further including a raised ridge between said second and third regions to prevent said rod from leaving said third region.

8. The device of claim 7, wherein said contour pushes said rod from said third region into said second region of at least one downward sloping contour when said outer structure is lowered.

9. The device of claim 8, wherein said upper surface of said contour further includes an arc-shaped surface to push said rod into a first semi-circular contour when said outer structure is lowered.

10. The device of claim 1, wherein said at least one series of regions comprises a plurality of regions located at laterally opposite ends of the first side and at least two series of regions located at laterally opposite ends of the second side.

11. The device of claim 1, wherein said at least one rod is perpendicular to said first side and said second side of said inner structure.

12. The device of claim 1, wherein said at least one rod passes from said first side of said inner structure to said second side of said inner structure during vertical movement.

13. The device of claim 12, wherein said at least one rod comprises at least two rods, said rods parallel to each other.

14. The device of claim 1, wherein said plurality of semi-circular contours is comprised of nine semi-circular contours.

15. The device of claim 1, wherein said plurality of semi-circular contours are spaced one inch apart.

16. The apparatus of claim 1 wherein said wherein each of said downward sloping contours have a uniform angle between thirty and sixty degrees to guide said one rod in a upward and laterally outward direction.

17. The apparatus of claim 1 wherein all components are comprised of polymer.

18. The apparatus of claim 17 wherein said components are comprised of a hollow polymer

19. A height-adjustable plyometric system comprised of:

at least one outer four-sided structure and at least one inner four-sided structure wherein said outer four-sided structure and said inner four-sided structure are telescoping;

a cylindrical rod;

wherein at least a first side and a second side of said inner structure have at least one slot having a diameter equal to or larger than said cylindrical face of at least one rod;

wherein at least two sides of said outer four-sided structure have a plurality of circular contours, wherein said circular contours are adjoined by a straight segmented contour and wherein said straight segmented contour is down-ward sloping;

wherein said series of contours begins at an angled upper surface and ends at an angled lower surface;

wherein said semi-circular contours have a radius equal to or larger than said cylindrical face of at least one rod; and

wherein each of said downward sloping contours has a uniform angled between twenty and seventy degrees to guide said one rod in an upward and laterally outward direction.

20. The system of 19 which is comprised of engineered lumber having alternating grain layers.
