High-tension safety net in a trampoline
Embodiments of the invention provide a high-tension safety net that may be attached to a trampoline using a plurality of safety poles. The safety poles may be attached to the frame of the trampoline. The safety poles include a plurality of top caps, each top cap adapted to receive and hold a tether attached to the safety net. The safety net may include a high-tension line at its top that attaches to the plurality of tethers. The safe net may be attached to the trampoline following a set of assembly procedures that does not require trampoline assembly workers of average height to use a ladder to attach the safety net.
1. A trampoline, comprising:
a frame;
a flexible mat;
a plurality of resilient members attached to the frame and to the flexible mat, wherein the resilient members receive kinetic energy from a user jumping on the flexible mat, causing the user to rise above a surface of the flexible mat;
a plurality of safety poles attached to the frame and residing substantially above the surface of the flexible mat; and
a safety net removably attached at a top portion of each safety pole of the plurality of safety poles, the safety net having an upper high tension line attached at an upper end of the safety net and a lower high tension line removably attached to a mid-section of each safety pole of the plurality of safety poles, wherein a region of the safety net between the upper high tension line and the lower high tension line resides at a higher tension than other regions of the safety net.
2. The trampoline of claim 1 wherein the region of the safety net between the upper high-tension line and the lower high-tension line withstands forces in a vertical range of 20-30 N and in a horizontal range of 40-50 N.
3. The trampoline of claim 1 wherein the safety net is removably attached to the top portion of each safety pole of the plurality of safety poles by a tether of a plurality of tethers attached to the safety net.
4. The trampoline of claim 3 wherein the top portion of each safety pole of the plurality of safety poles comprises a removable top cap, wherein the removable top cap includes a hook configured for attachment to a loop on an end portion of the tether of the plurality of tethers.
5. The trampoline of claim 3 wherein the top portion of each safety pole of the plurality of safety poles further comprises a removable top cap, wherein the removable top cap includes an internal cylinder configured to retain a loop on an end of the tether of the plurality of tethers.
6. The trampoline of claim 1 wherein the lower high-tension line is removably attached to each safety pole of the plurality of safety poles by a plurality of tethers.
7. The trampoline of claim 1 , further comprising:
an edge pad resting on an upper surface of the frame and extending to the flexible mat, wherein the edge pad includes a material to absorb shock from the user falling on the edge pad; and
a connector attached at a lower end of the safety net below the lower high-tension line, wherein the connector may be removably attached to the edge pad.
8. The trampoline of claim 7 wherein the connector is removably attached by one of a zipper, buttons, a belt, string, rope, snaps, and hook and loop fasteners.
9. The trampoline of claim 1 wherein each pole of the plurality of safety poles leans outward from the frame by a predetermined degree.
10. The trampoline of claim 9 wherein the predetermined degree resides in a range from greater than 1 degree to greater than or equal to 20 degrees.
11. The trampoline of claim 10 wherein the predetermine degree resides in a range from greater than or equal to 6 degrees to greater than or equal to 10 degrees.
12. The trampoline of claim 1 wherein the frame is substantially shaped as one of a rectangle, square, circle, oval, and stadium.
