Claims10
A trampoline having a safety enclosure, comprising:
- a trampoline comprising a frame and a rebounding mat coupled to the frame via plural spring members;
- a safety enclosure comprising plural independent poles extending above the rebounding mat and a flexible material coupled to the poles;
- and
- a resilient mechanism connected between the poles and the frame (a) to store energy upon an impact to the enclosure which causes at least one entire pole to move downwardly and (b) to release energy to return the at least one pole upwardly once the impact force is removed.
