Multi-positioned angled step and risers
View Patent ↗An adjustable stepping structure for aerobic exercise is disclosed having a platform and a plurality of support elements. The support elements include a downwardly arcuate notch or channel for receiving a sidewall or endwall of the platform, allowing the platform to be arranged in multiple angled orientations.
1. An adjustable stepping structure for aerobic exercise, comprising:
an elongated platform having a top surface for stepping and sidewalls extending downward from the top surface; and
at least two support elements, said support elements having an upper portion and a base, said base extending laterally outward from said upper portion;
wherein the platform can be supported in a horizontal orientation relative to a floor surface by placing the platform on top of the at least two support elements, with the upper portion of the support elements formed to nest within a lower interior portion of the platform between said sidewalls;
wherein the platform can be supported in a first angled orientation relative to the floor surface by placing a first end of the platform on the floor surface and a second end of the platform on a first one of the support elements, the second end of the platform and the first support element secured together by a notch interface.
2. The adjustable stepping structure of claim 1 ,
wherein the platform is substantially rectangular having sidewalls and endwalls and can be supported in a second angled orientation relative to the floor surface by placing a first sidewall of the platform on the floor surface and a second sidewall of the platform on the at least two support elements; and
wherein a first angle of the top surface with respect to the floor surface in the first angled orientation is less than a second angle of the top surface with respect to the floor surface in the second angled orientation.
3. The adjustable stepping structure of claim 1 ,
wherein the at least one two support elements have an open center cavity.
4. The adjustable stepping structure of claim 1 ,
wherein the at least one two support elements have a telescoping relationship.
5. The adjustable stepping structure of claim 1 ,
wherein the upper portion of said support elements is formed to nest within a lower portion of an upper adjacent support element.
6. The adjustable stepping structure of claim 1 ,
wherein the platform can be supported in a third angled orientation relative to the floor surface by placing a first end of the platform on the floor surface and a second end of the platform on a first support element, said first support element being vertically stacked upon a second support element.
7. The adjustable stepping structure of claim 6 ,
wherein the upper portion of said second support element is formed to nest within a lower portion of said first support element.
8. The adjustable stepping structure of claim 1 ,
wherein said notch interface comprises a non-slip surface.
9. The adjustable stepping structure of claim 1 ,
wherein said notch interface comprises a tab-in-notch interface.
10. The adjustable stepping structure of claim 1 ,
wherein said notch interface comprises at least two notches.
11. An adjustable stepping structure for aerobic exercise, comprising:
an elongated platform having a top surface for stepping and sidewalls extending downward from the top surface; and
at least one support element, said support elements having an upper portion and a base, said base extending laterally outward from said upper portion;
wherein the platform can be supported in a horizontal orientation relative to a floor surface by placing the platform on top of the support element, with the upper portion of the support element formed to nest within a lower interior portion of the platform between said sidewalls;
wherein the platform can be supported in a first angled orientation relative to the floor surface by placing a first end of the platform on the floor surface and a second end of the platform on the support element, the second end of the platform and the first support element secured together by a notch interface between the sidewall of the platform the upper portion of the support element.
12. The adjustable stepping structure of claim 11 ,
wherein the platform is substantially rectangular having sidewalls and endwalls and can be supported in a second angled orientation relative to the floor surface by placing a first sidewall of the platform on the floor surface and a second sidewall of the platform on two support elements; and
wherein a first angle of the top surface with respect to the floor surface in the first angled orientation is less than a second angle of the top surface with respect to the floor surface in the second angled orientation.
13. The adjustable stepping structure of claim 11 ,
wherein the support element has an open center cavity.
14. The adjustable stepping structure of claim 11 ,
wherein the upper portion of the support element is formed to nest within a lower portion of an upper adjacent support element.
15. The adjustable stepping structure of claim 11 ,
wherein the platform can be supported in a third angled orientation relative to the floor surface by placing a first end of the platform on the floor surface and a second end of the platform on a first support element, said first support element being vertically stacked upon a second support element.
16. The adjustable stepping structure of claim 15 ,
wherein the upper portion of said second support element is formed to nest within a lower portion of said first support element.
17. The adjustable stepping structure of claim 11 ,
wherein said notch interface comprises a non-slip surface.
18. The adjustable stepping structure of claim 11 ,
wherein said notch interface comprises a tab-in-notch interface.
19. The adjustable stepping structure of claim 11 ,
wherein said notch interface comprises at least two notches.
20. An adjustable stepping structure for aerobic exercise, comprising:
an elongated platform having a top surface for stepping and sidewalls extending downward from the top surface; and
at least two support elements, said support elements having an upper portion, a base, and an open center, said base extending laterally outward from said upper portion;
wherein the platform can be supported in a horizontal orientation relative to a floor surface by placing the platform on top of the at least two support elements, with the upper portion of a first support element formed to nest within a first lower interior portion of a first end of the platform between said sidewalls and the upper portion of a second support element formed to nest within a second lower interior portion of a second end of the platform between said sidewalls;
wherein the platform can be supported in a first angled orientation relative to the floor surface by placing a first end of the platform on the floor surface and a second end of the platform on a first one of the support elements, the second end of the platform and the first support element secured together by notch interface.
