Abstract

A plyometric box for includes a platform, a first pair of opposed sidewalls, and a second pair of opposed sidewalls. Each sidewall extends downwardly from the platform, and includes a first side, an opposed second side, a first pair of stacking ribs on an interior surface of the sidewall proximate the first side, and a second pair of stacking ribs on an interior surface of the sidewall proximate the second side. Each stacking rib extends downwardly from the platform along the sidewall and a bottom surface of each stacking rib is spaced upwardly from a bottom edge of the sidewall.

First claim

What is claimed is:

1. A plyometric box, comprising:
a platform; and
a first pair of opposed sidewalls and a second pair of opposed sidewalls rotationally fixed with respect to one another, each sidewall extending downwardly from the platform and including a first side, an opposed second side, a first stacking rib on an interior surface of the sidewall proximate the first side, and a second stacking rib on an interior surface of the sidewall proximate the second side,
wherein each of the first and second stacking ribs extends downwardly from the platform along the respective sidewall and has a vertically-extending inner edge, an entirety of the inner edge being exposed, and
wherein each of the first and second stacking ribs has a bottom surface extending outwardly into an interior of the plyometric box, and wherein the bottom surface of each of the first and second stacking ribs is spaced upwardly from a bottom edge of the respective sidewall.

2. The plyometric box of claim 1 , wherein each sidewall further includes a plurality of vertical wall support ribs, and each of the first and second stacking ribs extends outwardly from one of the vertical wall support ribs into the interior of the plyometric box.

3. The plyometric box of claim 2 , further comprising a plurality of fillets, each fillet positioned at an intersection of the bottom surface of one of the first and second stacking ribs and an interior edge of one of the vertical wall support ribs.

4. The plyometric box of claim 2 , wherein an intersection of a top surface of the platform and an exterior surface of each sidewall is rounded over with a first radius, and a fillet positioned at an intersection of the bottom surface of one of the first and second stacking ribs and an interior edge of one of the vertical wall support ribs has a second radius that is substantially the same as the first radius.

5. The plyometric box of claim 1 , wherein an intersection of the bottom surface and an interior edge of each of the first and second stacking ribs is rounded over.

6. The plyometric box of claim 1 , wherein an intersection of a top surface of the platform and an exterior surface of each sidewall is rounded over.

7. The plyometric box of claim 1 , wherein the first side of each sidewall is connected to the second side of an adjacent sidewall to form a corner of the plyometric box.

8. The plyometric box of claim 1 , further comprising:
an upwardly facing shoulder at a top edge of each sidewall; and
a lip extending inwardly from the top edge of each sidewall beneath the platform,
wherein a bottom surface of a rounded over peripheral edge of the platform is seated on the upwardly facing shoulders of the sidewalls.

9. The plyometric box of claim 8 , wherein the platform is secured to each of the lips with a plurality of fasteners.

10. The plyometric box of claim 1 , wherein each sidewall extends downwardly and outwardly from the platform at an angle of approximately 2-10° with respect to vertical.

11. The plyometric box of claim 1 , further comprising a plurality of elongated apertures, each aperture formed proximate an upper edge of one of the sidewalls.

12. The plyometric box of claim 1 , further comprising a plurality of recesses formed in a top surface of the platform and arranged in an array.

13. The plyometric box of claim 1 , further comprising:
a curved arm formed along the first side of each sidewall and defining a corner of the plyometric box;
a shoulder formed at the second side of each sidewall; and
a lip extending laterally outwardly from the second side of each sidewall,
wherein an end of the curved arm of each sidewall is nested against one of the shoulders and an exterior surface of the lip of an adjacent sidewall.

14. The plyometric box of claim 13 , wherein each curved arm is secured to the lip of the adjacent sidewall with a plurality of fasteners.

15. The plyometric box of claim 1 , further comprising a notch formed in each of the sidewalls, the notch including a pair of opposed notch sidewalls extending upwardly from the bottom edge of the sidewall and an upper surface extending between the opposed notch sidewalls.

16. The plyometric box of claim 1 , wherein the first stacking rib of each sidewall is part of a first pair of stacking ribs proximate the first side of the sidewall, and the second stacking rib of each sidewall is part of a second pair of stacking ribs proximate the second side of the sidewall.

17. A stack of plyometric boxes including a plyometric box according to claim 1 and a second plyometric box, wherein the plyometric box is stacked on top of the second plyometric box such that a top surface of the second plyometric box engages the bottom surfaces of the first and second stacking ribs of the plyometric box.

18. The stack of plyometric boxes of claim 17 , wherein the plyometric box and the second plyometric box have different heights.

19. The stack of plyometric boxes of claim 17 , wherein the plyometric box and the second plyometric box are configured for stacking such that the second plyometric box is stacked upon the plyometric box.

20. A plyometric box, comprising:
a platform; and
a first pair of opposed sidewalls and a second pair of opposed sidewalls rotationally fixed with respect to one another, each sidewall extending downwardly from the platform and including a first side and an opposed second side,
wherein each sidewall comprises a curved arm formed along the first side of the sidewall and defining a corner of the plyometric box, a shoulder formed at the second side of the sidewall, and a lip extending laterally outwardly from the second side of the sidewall, such that the lip is recessed from an exterior surface of the sidewall, and the shoulder extends from the exterior surface to the lip, and
wherein an end of the curved arm of each sidewall is nested against one of the shoulders and an exterior surface of the lip of an adjacent sidewall.

21. The plyometric box of claim 20 , wherein each sidewall includes a plurality of stacking ribs each having a bottom surface extending outwardly into an interior of the plyometric box, and wherein the bottom surface of each of the stacking ribs is spaced upwardly from a bottom edge of one of the sidewalls.

22. The plyometric box of claim 20 , further comprising:
an upwardly facing shoulder at a top edge of each sidewall; and
a lip extending inwardly from the top edge of each sidewall beneath the platform,
wherein a bottom surface of a rounded over peripheral edge of the platform is seated on the upwardly facing shoulders of the sidewalls.

23. A plyometric box, comprising:
a platform;
a first pair of opposed sidewalls and a second pair of opposed sidewalls, each sidewall extending downwardly from the platform, including a first side, an opposed second side, a bottom edge, a top edge, an aperture extending through the sidewall proximate the top edge, a first stacking rib on an interior surface of the sidewall between the aperture and the first side, and a second stacking rib on the interior surface of the sidewall between the aperture and the second side; and
a plurality of vertical wall support ribs, each vertical wall support rib extending along one of the sidewalls,
wherein each of the first and second stacking ribs has a bottom surface extending outwardly into an interior of the plyometric box, and wherein the bottom surface of each of the first and second stacking ribs is spaced upwardly from the bo
