Abstract:
1. A foldable trampoline, comprising: a frame consisting of a plurality of frame sections; a jumping bed located within said frame; a plurality of elastic elements, each of which having an outer end fixedly connected to said frame, and an inner end fixedly connected to an outer periphery of said jumping bed, so that said jumping bed is tightly stretched over said frame to provide a required rebounding force; and a plurality of supporting legs separately connected to each joint of two said frame sections that are adjacent to one another; and at least two knuckle mechanisms provided at two opposite ones of said joints of said frame sections; said knuckle mechanism including two clamp brackets separately provided at two opposed ends of two said adjacent frame sections at said joint; said clamp brackets being fixedly connected at respective rear ends to said frame sections, and having a front end formed into two spaced arms; said front end of each said clamp bracket extending forward to project beyond said end of said frame sections by a predetermined length and then turned downward to form two lug portions; said lug portions of said two opposed clamp brackets being overlapped and pivotally connected to each other via a shaft pin extended therethrough; and said shaft pin also being extended through one said supporting leg located thereat, such that two said frame sections connected via said knuckle mechanism may be pivotally turned about said shaft pin toward two lateral sides of said supporting leg located thereat.
