Abstract
A hinge bracket has a positioning disk adapted to be abutted to one side of the leg of the frame and having a first cutout and a second cutout peripherally defined around the positioning disk and a pad sandwiched between the positioning disk and one of the second leaf springs. The pad has a finger alternately corresponding to the first cutout and the second cutout so that the frame is able to be supported at a first position or the frame is able to be extended at a second position to be in parallel with the base to minimize space taken when stored or transported.
