Abstract
A 180-degree folding support joint includes a pair of joint members each including an outer wall and an inner wall and defining an engaging slot therebetween for disposing the inner wall of the other joint member therein, wherein a frame leg is adapted to affix on each joint member in such a manner that in a folded condition, each frame leg is adapted for pivotally rotating 180 degrees from each other in order to pivotally fold the frame legs together, and in an unfolded condition, each joint member is biased against each other in order to lock up the rotation of the joint members, so as to align the frame legs with each other.
