Quarter-foldable rebounder with improved features

A quarter-foldable rebounder, comprising:

• (a) a frame of circular configuration having an upperside and underside spaced apart from one another and inner and outer peripheral sides spaced from one another, said inner peripheral side defining a central opening, said frame including
• (i) four one-piece molded quarter-frame segments having curved configurations and opposite ends and being successively arranged end-to-end with one another, each of said quarter-frame segments supporting a rod in an arcuate configuration,
• (ii) a pair of half-fold hinges integrally formed on first ends of said opposite ends of said quarter-frame segments such that said half-fold hinges are spaced apart about one hundred eighty degrees from one another and pivotally interconnect said first ends of said quarter-frame segments such that said quarter-frame segments can be pivoted relative to one another about a pair of half-fold axes defined by said half-fold hinges so that said frame can be folded between an unfolded erect condition and a half-folded condition, and
• (iii) a pair of quarter-fold hinges integrally formed on second ends of said opposite ends of said quarter-frame segments such that said quarter-fold hinges are spaced apart about one hundred eighty decrees from one another and located between and spaced apart about ninety decrees from said half-fold hinges and pivotally interconnect said second ends of said quarter-frame segments such that said quarter-frame segments can be pivoted relative to one another about a pair of quarter-fold axes defined by said quarter-fold hinges so that said frame can be folded between said half-folded condition and a quarter-folded storage condition;
• (b) a mat of resilient flexible material disposed in said opening of said frame and having an outer peripheral edge of a circular configuration spaced inwardly from said inner peripheral side of said frame so as to define an annular gap therebetween;
• (c) a plurality of pairs of yieldably resilient elements disposed in said opening of said frame and across said annular gap and spaced apart from one another circumferentially about said outer peripheral edge of said mat and said inner peripheral side of said frame and extending therebetween so as to interconnect said mat to said rods supported by said quarter-frame segments and thereby hold said mat under a preset magnitude of tension;
• and
• (d) a plurality of legs each having a pair of opposite ends and being connected to said frame for undergoing movement relative to said underside of said frame between erected positions in which said legs extend transverse to and below said underside of said frame so as to support said frame and mat substantially parallel to and above a support surface when said legs rest on the support surface and folded positions in which said legs extend along said underside of said frame so as to permit said frame to be folded between said unfolded erect condition and said quarter-folded storage condition, wherein two of said quarter-frame segments has one pair of wells formed in said underside thereof and two of said quarter-frame segments having two pairs of wells formed in said underside thereof, each of said legs being pivotally mounted at one end in one of said pair of wells of each pair thereof for undergoing movement between said erected and folded positions and being receivable at the other end within the other of said pair of wells of each pair thereof when said legs is disposed at said folded position.
