Abstract
A spring arrangement for a trampoline includes a rebounding surface, a frame structure having a top portion and a bottom portion, and a plurality of spring members that are mechanically coupled between the rebounding surface and the frame structure. A first group of spring members are mechanically coupled to the top portion of the frame structure and a second group of spring members are mechanically coupled to the bottom portion of the frame structure. In one exemplary embodiment, the spring members of the first group and the second group are alternately arranged along the frame structure. In another exemplary embodiment, the frame structure is formed by a plurality of frame members.
Claims30
A trampoline, comprising:
- a rebounding surface;
- a single frame structure comprising a top portion and a bottom portion;
- and
- a plurality of spring members mechanically coupled between the rebounding surface and the single frame structure, a first group of spring members being mechanically coupled to the top portion of the single frame structure through an aperture in the top portion of the single frame structure and a second group of spring members being mechanically coupled to the bottom portion of the single frame structure through an aperture in the bottom portion of the single frame structure, and an end of each of the first group and second group of spring members that is coupled to the rebounding surface being in substantially the same plane.
A trampoline, comprising:
- a single rebounding surface comprising a single edge;
- a frame structure comprising a top portion and a bottom portion;
- and
- a plurality of spring members mechanically coupled between the single edge of the single rebounding surface and the frame structure, a first group of spring members of the plurality of spring members being mechanically coupled to the top portion of the frame structure through an aperture in the top portion of the frame structure and a second group of spring members of the plurality of spring members being mechanically coupled to the bottom portion of the frame structure through an aperture in the bottom portion of the frame structure.
A trampoline, comprising:
- a rebounding surface;
- a frame structure having at least one frame member, the frame member comprising a top portion and a bottom portion;
- and
- a plurality of spring members mechanically coupled between the rebounding surface and the frame member, a first group of spring members being mechanically coupled to the top portion of the frame member through an aperture in the top portion of the frame structure and a second group of spring members being mechanically coupled to the bottom portion of the frame member through an aperture in the bottom portion of the single frame structure, and an end of each of the first group and second group of spring members that is coupled to the rebounding surface being in substantially the same plane.
