Problems solved by technology
However, injuries have sometimes resulted when a person jumping on a trampoline would land too near the boundary of the rebounding surface and strike the trampoline frame or fall from the trampoline to the ground.
However, these devices suffer from various drawbacks, in some cases i

Embodiment Construction
[0026]Trampoline Fence
[0027]Trampolines come in a variety of configurations and sizes. A popular trampoline 20 is shown in FIGS. 1-2. The illustrated trampoline has a circular frame 34 supported by multiple U-shaped tubular legs 36. The U-shaped legs have two vertically-extending sections 37 connected by a horizontal section that rests on the ground. The upper ends of the vertical leg sections 37 are secured to the frame 34 by welds. For ease in storage, it is convenient for the legs to be removable. This is made possible by providing a swage joint 38 in each vertical leg section 37. (In some embodiments, the legs 36 are not removable but are fixedly secured to the frame 34. In such embodiments, it is sometimes desirable to secure the legs to the ground, as by coupling to screw-in ground anchors. The coupling can be inelastic or elastic.)
[0028]In the preferred embodiment, at least the top of frame 34 is covered with a resilient foam material to help cushion any impact against the fr...

Abstract
A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided in the preferred embodiment by a support system of independent poles, linked at their tops by a flexible strap or line. The trampoline may include a tubular frame supported by a plurality of legs with brackets securing the legs to the frame tube without welds. The trampoline may also include an electronic accessory that is activated or that produces an electrical signal as a result of jumping on the trampoline.
