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. An impact anywhere on the fence causes the posts to flex inwardly, absorbing the force. Much of this impact injury is stored in system components and is subsequently returned, helping propel an errant jumper back onto to the rebounding surface. Numerous other embodiments and accessories are also detailed. Similar arrangements are suitable for use with above ground pools. |

DETAILED DESCRIPTION Trampoline Fence 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 ineleastic or elastic.
) 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 frame.
Many commercially available trampolines use 1.
92" O.
D.
frame tubing.
This can be covered by splitting 3.
0" I.
D.
extruded foam tubing, and securing a split half on top of the frame by tape or the like.
A plurality of spring members 39 tautly attach a sheet of sturdy fabric 40 to the frame 34 so that the fabric provides a rebounding surface or bed.
Other types of trampolines, having variations in structure such as individual legs secured by bolts or the like, will equally benefit from the present invention.
The foregoing trampoline is augmented by an enclosure system 30 that provides a protective and interactive environment for a trampoline user.
The illustrated system 30 includes a plurality of posts 44 which extend vertically.
Each post 44 is secured to a vertical section 37 of one of the legs 36.
For the purpose of this disclosure, each post 44 is referred to as having an upper end portion 46, a wall supported portion 48 located above the level of the rebounding surface 40, a lower portion 50 located below the surface 40, and a lower end portion 52 which extends to ground level
