Abstract

A plyometric jump box includes a foam outer box having six sides. Each side includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³. The box defines a cavity therein. A support structure is disposed inside of the cavity and is coupled to each of the sides so as to provide support to each of the sides.

Claims

1. A plyometric jump box, comprising:

(a) a foam outer box having six sides, each side including a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³, the box defining a cavity therein; and

(b) a support structure disposed inside of the cavity and coupled to each of the sides so as to provide support to each of the sides.

2. The plyometric jump box of claim 1, wherein the support structure comprises:

(a) a first planar member that includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³; and

(b) a second planar member that includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³, the second planar member being transverse to the first planar member.

3. The plyometric jump box of claim 1, wherein at least two opposing sides of the six sides include a gripping member.

4. The plyometric jump box of claim 3, wherein at least one gripping member comprises a hole defined by one of the sides and passing therethrough.

5. The plyometric jump box of claim 4, wherein the hole has dimensions that are configured to prevent a user'"'"'s foot from passing therein.

6. The plyometric jump box of claim 1, wherein in the six sides comprise:

(a) a first pair of oppositely disposed sides in which each side has a first side height and a first side width, the first side width not being equal to the first side height;

(b) a second pair of oppositely disposed sides in which each side has a second side height and a second side length, the second height not being equal to the second side length, the second side height being equal to the first side height; and

(c) a third pair of oppositely disposed sides in which each side has a third side length and a third side width, the third side length not being equal to the third side width, the third side width being equal to the first side width, whereby the plyometric jump box provides three different jump heights depending on which of the six sides is placed down.

7. A jump box, comprising:

(a) a foam outer box having six sides, each side including a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³, the box defining a cavity therein;

(b) a first planar member that includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³, the first planar member disposed within the cavity and affixed to four of the six sides of the outer box; and

(c) a second planar member that includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³, the second planar member disposed within the cavity and being transverse to the first planar member, the second planar member affixed to four of the six sides of the outer box, but not affixed to two of the six sides to which the first planar member is affixed.

8. The jump box of claim 7, wherein at least two opposing sides of the six sides include a gripping member.

9. The jump box of claim 8, wherein at least one gripping member comprises a hole defined by one of the sides and passing therethrough.

10. The jump box of claim 9, wherein the hole has dimensions that are configured to prevent a user'"'"'s foot from passing therein.

11. The jump box of claim 7, wherein in the six sides comprise:

(a) a first pair of oppositely disposed sides in which each side has a first side height and a first side width, the first side width not being equal to the first side height;

(b) a second pair of oppositely disposed sides in which each side has a second side height and a second side length, the second height not being equal to the second side length, the second side height being equal to the first side height; and

(c) a third pair of oppositely disposed sides in which each side has a third side length and a third side width, the third side length not being equal to the third side width, the third side width being equal to the first side width, whereby the plyometric jump box provides three different jump heights depending on which of the six sides is placed down.

12. A method of making a plyometric jump box, comprising the steps of:

(a) forming a first pair of foam sides in which each side has a first side height and a first side width, the first side width not being equal to the first side height and in which each of the first pair of foam sides includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³;

(b) forming a second pair of foam sides in which each side has a second side height and a second side length, the second height not being equal to the second side length, the second side height being equal to the first side height and in which each of the second pair of foam sides includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³;

(c) forming a third pair of foam sides in which each side has a third side length and a third side width, the third side length not being equal to the third side width, the third side width being equal to the first side width and in which each of the third pair of foam sides includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³;

(d) affixing the first pair of foam sides to the second pair of foam sides and to the third pair of foam sides and affixing the second pair of foam sides to the third pair of foam sides so as to form a box that defines a cavity therein, wherein each of the first pair of foam sides is disposed oppositely of each other and wherein each of the second pair of foam sides is disposed oppositely of each other and wherein each of the third pair of foam sides is disposed oppositely of each other; and

(e) disposing a support structure inside of the cavity and affixing the support structure to each of the sides so as to provide support to each of the sides.

13. The method of claim 12, wherein the affixing step is accomplished using an adhesive.

14. The method of claim 13, wherein the adhesive comprises an acrylic adhesive.

15. The method of claim 12, step of disposing a support structure comprises the steps of:

(a) affixing a first planar member that includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³ to a a second planar member that includes a 4 inch thick cross-linked polyethylene closed cell foam sheet material having a density of between 4 lbs./ft.³ and 6 lbs./ft.³, the second planar member being transverse to the first planar member, thereby generating the support structure;

(b) affixing the support structure to the first pair of foam sides, the second pair of foam sides and the third pair of foam sides.

16. The method of claim 12, further comprising the step of forming a gripping member on at least two opposing foam sides of the box.

17. The method of claim 16, wherein the step of forming a gripping member comprises defining a hole so as to pass through the at least two sides.

18. The method of claim 17, wherein the step of defining a hole comprises cutting a hole that has dimensions that are configured to prevent a user'"'"'s foot from passing therein.
