ABSTRACT:
A trampoline includes a trampoline frame and a jumping bed. The trampoline frame includes a leg portion disposed uprightly on a ground surface, and a looped frame portion mounted on top of the leg portion so as to be supported spacedly from and parallel to the ground surface. The looped frame portion confines a bed mounting space therewithin. The jumping bed includes a bed member with a peripheral portion and of a dimension smaller than that of the bed mounting space, and an elastic support unit having a plurality of folded elastic straps. Each of the elastic straps has opposite ends secured to the peripheral portion of the bed member and confines a passage for extension of the looped frame portion therethrough, thereby suspending elastically the bed member relative to the looped frame portion.
