Ball Storage Rack

Abstract

A ball storage rack comprises at least three support rods, two base members and a connecting member. When the ball storage rack stores balls, each base member can serves as a centre to be pivotally coupled to each support rod, as a result, the support rods can fold and unfold, in addition, the two base members are connected with each other by a connecting member. In such a manner, the whole structure strength can be improved; it is difficult to be damaged for the distortion caused by the weight of balls.
