Water trampoline

Abstract

A water trampoline includes an air cushion having predetermined size and buoyancy; a supporting ring detachably connected to a top surface of the air cushion, and including a lower ring having a diameter corresponding to that of the top surface of the air cushion, and an upper ring located above the lower ring by a predetermined height; and a jumping bed tightly stretched over the upper ring by a plurality of radially extended elastic elements. The jumping bed is located above the air cushion instead of in a central open space thereof, and therefore has effectively increased surface area and largely enhanced bearing strength to enable safer and more durable use of the water trampoline.

1 . A water trampoline, comprising: 
 an air cushion having predetermined size and buoyancy;    a supporting ring detachably connected to a top surface of said air cushion, said supporting ring including a lower ring having a diameter corresponding to that of said top surface of said air cushion, and an upper ring located above said lower ring by a predetermined height; and    a jumping bed tightly stretched over said upper ring by a plurality of radially extended elastic elements.    
   
   
       2 . The water trampoline as claimed in  claim 1 , wherein said supporting ring is detachably connected at said lower ring to said air cushion by a plurality of fastening straps provided on said top surface of said air cushion.  
   
   
       3 . The water trampoline as claimed in  claim 2 , wherein said fastening straps are provided on positions on said top surface of said air cushion having reinforcing patches provided thereat.  
   
   
       4 . The water trampoline as claimed in  claim 1 , wherein said elastic element comprises a coil spring having two connecting ends.  
   
   
       5 . The water trampoline as claimed in  claim 4 , wherein said elastic element is connected at one of said two connecting ends to an outer periphery of said jumping bed, and at the other said connecting end to said upper ring of said supporting ring.  
   
   
       6 . The water trampoline as claimed in  claim 1 , further comprising a protective cover adapted to cover a top of said supporting ring and said elastic elements.
