Abstract: A projectile launcher for launching a projectile is provided. The projectile launcher is arranged to be connected to a trampoline having a frame and a jumping mat, the jumping mat connected to the frame by resilient members, the projectile launcher including a propulsion element adapted to provide a motive force to propel a projectile and an energy extraction element arranged to be connected to a trampoline and to extract energy from the action of a user bouncing on the trampoline to provide power to the propulsion element.

Abstract: This invention concerns a trampoline comprising a flexible bounce mat connected to a frame by one or more resilient members such that the flexible bounce mat is held above the ground in tension. A plurality of support poles is arranged, in use, to extend upwardly from the frame and a surround of flexible material is arranged to be connected to the support poles to extend around and above the flexible bounce. An interface between the flexible bounce mat and surround may be inward of the resilient members. A cover comprising a sheet of material may extend from the surround over the resilient members to the frame. The trampoline may be without foam/padding material over at least some of the resilient members.
