Joint structure for a collapsible play yard

Abstract

A joint structure for a collapsible play yard, includes a U-shaped housing, a button-mount, a sliding block and a button. The U-shaped housing has a pair of side walls for pivoting with a pair of frame bar members each having a length of substantially flattened undersurface. The button-mount is formed with a sliding way, attached to one of the side walls. The sliding block is movable transversally engaging with the substantially flattened undersurface of both of the frame bar members in an engaged position, and movable to a released position to release both of the frame bar members for folding the collapsible play yard. The button connects with the sliding block and is biased by a resilient element for reciprocally sliding along the sliding way so as to drive the sliding block to the engaged position and the released position.

Dependencies are inferred from the claim text.
