发明名称 Foldable sports goal structure
摘要 A foldable sports goal structure includes a horizontal crossbar member supported at each end by vertically extending posts. A pair of tubular shaped first support members rearwardly extend from the lower ends of the posts, and a pair of tubular shaped second support members have front ends that fit into and extend rearwardly from the rear ends of the first support members. A pivot member rotatably connects the front and rear ends together. The first supporting member has a circular aperture on a side surface thereof that is formed continuously with a slot that extends to and terminates at the rear end of the first support member. The slot has a width that is smaller than the diameter of the second support member and the circular aperture has a diameter substantially equal to the diameter of the second support member. The second support member travels through the slot and into the circular aperture when the second support member is rotated about the pivot member.
