| 摘要 |
A portable playyard includes a top frame defining a top opening, a bottom frame, a plurality of circular inflatable supporters spacedly bridging the top and bottom frames, a boundary shelter supported by the top frame to define a playyard cavity within the boundary shelter, the top frame, and the bottom frame; and an air valve provided at the inflatable supporters. Each of the inflatable supporters, having an air chamber, is outwardly and inclinedly extended from the top frame to the bottom frame to evenly distribute and support a downward force applied on the top frame so as to prevent the playyard from being accidentally collapsed.
