Patent attributes
A changing table for a playard includes a front and rear rails, and a pair of side rails connected to each other to form a platform substantially rectangular or elliptical in shape. A first pivot joint with a button mounted at the exterior is provided at one end of one of the pair of side rails. One end of the rear rail is attached to a second pivot joint which corresponds to the first pivot joint in structure. The first and second pivot joints may be coupled to each other to define a space therein to receive a toothed disc and a compression spring. By means of the cooperation between the pivot joints, toothed disc and compression spring, the first pivot joint moved by the side rail is rotatable within a predetermined angular range and may be locked at a predetermined angle. By such arrangement, the user can readily actuate the button of the first pivot joint to swing the side rail attached to the first pivot joint, to thereby conveniently fold and/or unfold the changing table.
