Abstract

A trampoline has a trampoline bed, a set of trampoline springs, and a trampoline frame retaining the trampoline bed. The trampoline frame has a horizontal tube frame. The horizontal tube frame is made in sections. A corrugated upper surface is formed on the horizontal tube frame including an inside tube connected to an outside tube. An inside tube has an inside tube wave top and an outside view has an outside tube wave top. Preferably, the horizontal tube frame further includes a corrugated lower surface formed on the inside tube and on outside tube so that the inside tube has an inside tube wave bottom and the outside tube has an outside tube wave bottom.

First claim

The invention claimed is:

1. A trampoline comprising:
a trampoline frame;
a set of trampoline springs mounted to the trampoline frame;
a trampoline bed held in tension by the trampoline springs, wherein the set of trampoline springs retain the trampoline bed, wherein the trampoline frame has a horizontal tube frame as a portion of the trampoline frame, wherein the horizontal tube frame is made in sections including at least a first section and a second section; and
a corrugated upper surface formed on the horizontal tube frame first and second sections including an inside tube portion of the first section and an outside tube portion of the second section wherein the first and second sections are configured to be connected together, wherein the inside tube has the inside tube wave top and wherein the outside tube has an outside tube wave top that nest together to form corrugated interfaces, the corrugated interfaces configured to act as springs against each other to form a tighter engagement between the first and second sections.

2. The trampoline of claim 1 , wherein the inside tube wave top has an inside tube first top corner, and an inside tube second top corner.

3. The trampoline of claim 2 , wherein the outside tube has an outside tube first top corner and an outside tube second top corner.

4. The trampoline of claim 3 , wherein the inside tube first top corner engages to the outside tube first top corner; and wherein the inside tube second top corner engages to the outside tube second top corner.

5. The trampoline of claim 4 , further including a first inside tube crease that engages to a first outside tube crease; and further including a second inside tube crease that engages to a second outside tube crease.

6. The trampoline of claim 4 , wherein the inside tube wave top is aligned with the outside tube wave top and the outside tube wave top is aligned with a lower ridge that extends downwardly from a lower surface of the outside tube, wherein the lower ridge is formed opposite the outside tube wave top.

7. The trampoline of claim 4 , further including a weighted base that is configured to be filled by a liquid, wherein the weighted base is attached to the horizontal tube frame.

8. The trampoline of claim 1 , wherein the horizontal tube frame further includes a corrugated lower surface formed on the inside tube and on the outside tube, wherein the inside tube has an inside tube wave bottom and wherein the outside tube has an outside tube wave bottom.

9. The trampoline of claim 8 , wherein the inside tube wave top has an inside tube first top corner, and an inside tube second top corner.

10. The trampoline of claim 9 , wherein the outside tube has an outside tube first top corner and an outside tube second top corner.

11. The trampoline of claim 10 , wherein the inside tube first top corner engages to the outside tube first top corner; and wherein the inside tube second top corner engages to the outside tube second top corner.

12. The trampoline of claim 10 , further including a first inside tube crease that engages to a first outside tube crease; and further including a second inside tube crease that engages to a second outside tube crease.

13. The trampoline of claim 10 , wherein the inside tube wave top is aligned with the outside tube wave top and the outside tube wave top is aligned with a lower ridge that extends downwardly from a lower surface of the outside tube, wherein the lower ridge is formed opposite the outside tube wave top.

14. The trampoline of claim 10 , further including a weighted base that is configured to be filled by a liquid, wherein the weighted base is attached to the horizontal tube frame.
